17 Tips To Cure fibromyalgia symptoms

Introduction to Fibromyalgia Symptoms and Possible Causes

Fibromyalgia surely ranks with the most annoying, if not the most debilitating of the long-term, chronic medical conditions. The symptoms run the gamut from nerve and muscle pain to nausea, constipation, and diarrhea. WebMD.com gives the following list of potential symptoms:

  • Muscle pain/spasms/tightness
  • Fatigue, decreased, or low energy
  • Insomnia and/or fatigue on awakening
  • Waking stiffness or stiffness after staying in one position
  • Reduced memory, concentration, or cognition
  • Irritable bowel syndrome, bloating, cramps, constipation, and diarrhea
  • Tension or migraine headaches
  • Temporomandibular Joint Disorders (TMJ) or tenderness of jaw muscles
  • Odor, food, or light sensitivities
  • Depression or anxiety
  • Tingling or numbness in the extremities
  • Irritable bladder syndrome, i.e., needing to go frequently
  • Low or reduced tolerance for exercise
  • A sense of swelling of hands or feet without actual swelling

Fibromyalgia suffers may experience one, some, or all of these symptoms but, and this is the real rub, no one really knows why. Speculation focuses on factors from genetics to pollution and from stress to hormonal imbalances. Medical science performs very well in identifying the causes and treatments for specific issues, but not well at all when symptoms are diffuse and non-specific. Still, while doctors don’t offer a magic bullet for fibromyalgia their approach to treating generic illness, trial and error, nevertheless offers sufferers hope. Discuss all speculative self-treatments with your doctor.

Part I: Diet

1 Exclude Inflammatory Foods

Since fibromyalgia often presents with food testing an exclusionary diet might help. The big seven known inflammatory foods are: tomatoes, potatoes, eggplant, honey, milk, wheat, and peanuts. Most of the trouble with tomatoes comes from the skin and seeds. If you have inflammation, difficulty concentrating, or ADD/ADHD it’s not a bad idea to try excluding them instead of taking drugs. Allergenic and inflammatory foods can sometimes be reintroduced to the diet later.

2 Eat Cooked Foods

It’s hard to extract much nutrition from raw veggies and the brain only runs on glucose from the liver. One of the problems with a raw food diet is that its associated weight loss amounts to starvation. How you cook food matters, too. For example, a low-inflammation diet calls for a lot of soups and stews because they are cooked at low temperatures. In turn, that means less cross-glycolated proteins to put pressure on the liver and cause inflammation.

3 Try eating seafood regularly

Most people do fine without meat protein. The problem is that our soils and waters are minerally depleted. That has been known since the 1930s. Two things came from the US Senate-commissioned studies of soil demineralization . First, we reorganized the processed food industry to produce minerally fortified products, hence all the additives. Most of that happened in the 1940s and 1950s, though salt was iodized after 1924. Second, the livestock growers started feeding minerals. That causes other problems. In particular, they overfeed by about 10-to-1 to get enough bioavailable minerals. Most people get their minerals from meat. However, although nutritionists usually tell vegetarians that they have to take vitamin B-12 supplements–it’s bioavailable cobalt bound by a protein–most of them ignore the other trace minerals. Ocean fish provides those trace minerals, but it’s a good idea to avoid large fish like tuna in favor of smaller fish like salmon or sardines because of their lower levels of mercury.

4 Watch, but Don’t Worry Your Fats

The human body produces it’s own healthy fats. The brain is mostly fat. Maintaining it requires the body to manufacture very high quality phospholipids like DHA. Retinal cells use a lot of high quality phospholipids, too. Likewise all cell walls contain phospholipids. By contrast, fish oil is mostly triglycerides. Krill oil is an excellent source of choline, but you can easily get all the choline you need from two eggs and a slice of bacon, or by eating plenty of meat, and/or wheat germ. Most dietary fat gets digested, not absorbed. Most of what doesn’t get digested passes in bowel movements. A quick look into the toilet serves as a simple test of whether you’re eating too much dietary fat—greasy stools float.

5 Balance Your Proteins

Nutritionists can be quite vague about protein intake. However, in their book Protein Power, medical doctors Michael and Mary Dan Eades give more specific advice. Here’s an approximate formula as it relates to exercise:

Grams protein per day per pound of lean body mass
0 exercise: 0.5
1: 0.6
2: 0.7
3: 0.8
4: 0.9
5 athletic training: 1.0

Notice that you’ll need a body composition test to follow this advice accurately. Electrical impedance tests of lean body mass aren’t very accurate. Water displacement tests are better. These days, vendors provide lean body mass tests in most cities. Then it’s just plug-chug-go

6 Overall Diets

Until very recently most diet studies were of very modest quality. However, some researchers have begun to break that mold. In particular, Stanford’s A-to-Z study, while preliminary, tracked more than 300 pre-menopausal, overweight women for a full year. The participants were assigned randomly to follow Atkins (extremely low carbohydrate), Zone (low-carbohydrate, high protein), Ornish (very low fat), or USDA/Food LEARN (high carbohydrate/moderate-low fat) diet. The researches found that the women assigned to follow the Atkins diet both lost more weight (~10 pounds average weight lost in 1 year) and recorded metabolic effects as good or better than the other diets.

7 Spice Things Up

Countries with underdeveloped healthcare systems rely on eating a variety of foods to maintain good health. Remember the Big 5 spices: cinnamon, turmeric, ground coriander seed, ground fennel, and ground ginger. Research finds benefits to all five.

Part II: Sleep

Like diet, the topic of sleep attracts a lot of bad information. For example, while the modern 8-hour sleep cycle conforms to the modern work environment and the dominance of the electric light, that doesn’t make it ‘natural’ in the sense that most people use that term. From colonial records, we know that in the absence of electric lights, within a short period the sleep pattern deviates from the modern norm, often splitting into two sleeps divided by a period awake. Be that as it may, most people don’t enjoy the option of following their own natural sleeping pattern. Unfortunately, that means finding a way to conform to someone else’s schedule. Some tips:

8 Maintain Good Sleep Hygiene

In most cases, maintaining good sleep hygiene means avoiding daytime napping, and stimulants like coffee, tea, or chocolate before bed, as well as, sticking to a set waking time, and spending an adequate amount of time in bed. In addition, good sleepers associate their beds with sleep. That means no TV, reading, or radio in bed. Since alcohol disrupts deep sleep, avoid drinking before bed. Also, take the time to discuss any problems like sleep apnea or gastric reflux with a qualified doctor.

9 Get a Better Bed

Another factor within our control that often gets overlooked is a worn out or otherwise uncomfortable bed. An inadequate bed puts extra stress on pressure points and leads to the sort of tossing and turning that can cause the sort of micro-tears in muscles associated with fibromyalgia. Similarly, a physical therapist, doctor, or chiropractor can recommend a perfect, water-filled pillow that’s right for you.

10 Stay Warm at Night

This one is tough. Experts warn that using electric heating pads and blankets can lead to permanent loss of the body’s ability to regulate temperature. However, in their highly recommended manual The Arthritis Helpbook, Kate Loring and James Fries take the opposite tack saying: “Heat is most effective for reducing the pain associated with muscle tension and stiffness, and when there is little or no inflammation. It works by increasing the blood flow to the skin and muscles around the painful area. This, in turn, enhances muscle nutrition and relaxation. When the muscles relax, pain and stiffness decrease…. Warm baths, showers, a hot tub, sauna, or electric mattress pads are good ways to help soothe the whole body; these methods may be particularly beneficial for the person with fibromyalgia.” Alternatively, for those worried about body temperature self-regulation, pre-warming the bed or using microwavable foot warmers may reduce muscle spasms and other sleep disrupting problems with cold feet.

11 Self-Hypnosis/Sleep Recordings/White Noise

Psychologists and professional hypnotherapists have produced positively affirming sleep recordings for the mass market, many of which are freely available online or at low cost. Similarly, just as a sleep mask cuts off excess light, commercially available white noise generators mask distracting sound that could disrupt sleep.

Part III: Stress Management

In addition to evidence that fibromyalgia stems from general dietary issues, genetic factors, and sleep disorders, evidence suggests that some sufferers benefit significantly from techniques designed to decrease stress and increase a sense of well-being. These fall into two broad categories, balneotherapy/heat therapy/therapeutic massage, and brain oxygenation.

12 Massage and Heat Therapy

Balneotherapy, the scientific term for bath therapy covers a lot of ground from just taking a regular warm bath to a routine part of physical therapy. As a common element, these techniques heal and relax the body using heat, commonly through the use of an appliance like a hot tub, Jacuzzi, heated pool, or a heated float tank. Modern saunas and steam rooms often incorporate infrared heat therapy, which penetrates beyond the surface of the skin. Infrared pads and handheld self-massage appliances have become much more available. Standard massage and ultrasound may help, as well.

12 Brain Oxygenation

The old saying that laughter is the bed medicine holds a lot of truth. According to the Mayo Clinic laughter, it turns out releases endorphins, the body’s natural pain meds. Other entertainments like music induce the same effect. That in turn suggests a strategy that is at once new and very old, meditation. Newcomers to meditation general agree that while it won’t heal all ills, it will make most people feel at least 10% better. The real benefits often come from the practice of both deep regular breathing and bioenergetic breathing. Most people know about deep breathing. Bioenergetic breathing adds the additional element of breathing fast, rather than just deep. It’s an assertive, explosive form of breathing, not unlike laughing, that releases endorphins while realigning the ribs, shoulders and spine.

yoga To Cure fibromyalgia symptoms

Part IV: Exercise

Everyone recommends exercise to help fibromyalgia symptoms. The trouble is that exercise often hurts. It might be useful to consider exercise in gradual stages from the very light to the moderate.

13 Exercise In Bed

That’s right. Ever since Sanford Bennett (The Man Who Grew Young) wrote Exercising in Bed back in 1907, some people have taken his advice. The range of gentle self-massage and exercises that can be performed while warm and comfortable is really limited only by the imagination. Granted, it won’t turn you into an aerobics instructor, at least not overnight, but it can help to relieve muscle strain and improve joint mobility.

14 Myofascial Self-Release

The next step up from light exercise in bed, myofascial self-release focuses on maintaining skeletal alignment and releasing tension at muscular pressure points all over the body. Despite the hype, the truth about stretching is that it takes a long time to make any progress.

15 Yoga, etc.

Most people don’t realize it, but the original purpose of yoga was gentle, self-help for healing. Practices like yoga, Tai Chi, Qigong, gentle walks, and light swimming all help the body heal itself. If it’s too hard, remember that you can limit the amount of time you exercise between periods of rest.

supplements for fibromyalgia symptoms

Part V: Supplements

Never mind the echo chamber on the pharmaceutical companies dietary supplements make the companies that sell them a lot of money, too. Here’s one that might matter, either in the form of nicotinic acid or nicotinamide:

16 Niacin

In a 2008 study in the Journal of Neuroscience, researchers at the University of California at Irvine gave the human dose equivalent of 2,000 to 3,000 mg of vitamin B3 to mice with Alzheimer’s. (2) It worked. Kim Green, one of the researchers, is quoted as saying, “Cognitively, they were cured. They performed as if they’d never developed the disease.”

Now, let’s agree that Alzheimer’s is not quite the same as fibromyalgia. However, both affect the nervous system. And both conditions may be helped by niacin. Beware of pills, though. Fibromyalgia sufferers may be sensitive to the bulk fillers pill manufacturers use. Both nicotinic acid and niacinamide/nicotinamide are available in bulk in their pure form.

17 Other Supplements That Might Help

Some of the more common supplements that fibromyalgia sufferers recommend include Vitamin D-3, ginseng, reishi mushroom, cordyceps mushroom extract, and iodine. Vitamin D affects circadian rhythm so remember to take it in the morning, not at bedtime. Iodine may help if fibromyalgia symptoms are associated with a thyroid issue. The others may affect other hormone levels. Talk to your doctor before taking any supplements.

Walking to Manage the Symptoms of Fibromyalgia

Fibromyalgia is a condition that is known for the widespread pain that it causes. There are also some other signs and symptoms that go along with fibromyalgia:

  • Deep muscle pain
  • Tender points
  • Stiffness upon waking in the mornings
  • Problems sleeping
  • Fatigue
  • Depression/anxiety

There’s no doubt about it. The pain, fatigue, and other symptoms of fibromyalgia can make it quite difficult to do any sort of physical activity- even something as simple as walking. However, exercise- if done properly and you don’t overexert yourself- can actually be a very effective treatment for managing the symptoms of fibromyalgia.

Treatments for Managing Fibromyalgia Symptoms

There are several things that you can do to manage the signs and symptoms of fibromyalgia. Your doctor may recommend one or several of the following:

Medications- There are several medications that have been approved for the treatment of fibromyalgia symptoms like Lyrica, Cymbalta, and Savella.

Changes in lifestyle- You can do things such as: learn to manage stress, get more sleep, exercise more, eat better, and other changes you can make to manage the symptoms of fibromyalgia.

Physical therapy- Treatments such as massage therapy, ultrasound, heat therapy, hydrotherapy, and many more things are being used to assist in controlling the signs and symptoms of fibromyalgia.

Mental/emotional therapy- Visit a trained counselor or join a fibromyalgia support group- it helps to know that there are others who are experiencing the same things you are. If there’s not a group in your area, consider starting one.

Changes in diet- Know that there are specific foods that are thought to trigger fibromyalgia flares– you will want to get these out of your diet for good!

Alternative treatments- Try things such as acupuncture, massage, biofeedback, and more are being used in the treatment of fibromyalgia symptoms- just make sure that you go to a trained professional.

Walking For Fibromyalgia Symptoms

Exercise

Yes- exercise. It can actually be an extremely effective way to treat the signs and symptoms of fibromyalgia, including pain and problems with sleep. Exercise can offer a plethora of benefits including:

  • Boosting energy
  • Decreasing muscle stiffness/tension
  • Maintaining a healthy weight
  • Improvement in mood and overall feeling of well-being
  • Promoting a deep and restorative sleep
  • Muscle strengthening
  • Support of a healthy immune system

How to Begin an Exercise Program to Treat Fibromyalgia Symptoms

One of the most effective treatments for fibromyalgia signs and symptoms is participating in a regular, and low-intensity exercise program. However, as with any other fibromyalgia treatment program, you will need to consult with your physician, physical therapist, or a certified personal trainer. He/she will be able to come up with an exercise plan that is just for you. Since it will be tailored to fit your needs and abilities, it is one that you will be much more likely to stick with in the long run.

Additionally, it is vital that you start out slow with your new exercise plan. Of course, over time, you can increase your level of physical activity, but you don’t want to rush into anything. This is especially necessary if it’s been awhile since you have been physically active or if you have never participated in an exercise program before. You will want to take the time to build up your strength and stamina.

Keep in mind that you will most likely experience some increase in your pain and soreness when you first get started with your fibromyalgia treatment exercise program. That is completely normal. In a few days, this exercise-related pain should dissipate.

Over time, you’ll begin to notice that the fibromyalgia treatment exercise program is having a positive impact on both your physical and mental health. The mental benefits are likely to be pretty significant. Taking part in an exercise program will boost the levels of endorphins in the brain, which can help with pain reduction as well as reduce any anxiety/depression you may be experiencing.

Exercises You can Do to Manage Fibromyalgia Symptoms

The Center for Disease Control and Prevention, or CDC, recommends that adults aim to get at least 150 minutes each week of aerobic exercise of moderate intensity. This includes things such as swimming or walking. Additionally, adults should be getting two or more days each week of muscle strengthening exercises. This includes things such as push-ups and light weight lifting. Adults must also work in some exercises to promote flexibility. This includes exercises such as stretching, gentle yoga, and even Pilates.

Of course, you can keep this CDC goal in mind, but you must also pay close attention to your body. If you can’t quite reach the 150 minutes per week- that’s perfectly fine. It’s something you can try to build up to.

To ensure that you are participating in a well-rounded exercise program to help manage the signs and symptoms of fibromyalgia, you should try to incorporate a mix of the three: flexibility, aerobic, and strengthening exercises.

Exercising to Help you Thrive with Fibromyalgia

You really don’t have to spend hours in the gym to be able to manage the signs and symptoms of fibromyalgia. Know that the more you get into exercising, the more you will experience the benefits of the exercise.

It is possible that your physician may make some other suggestions in addition to exercise for managing the signs and symptoms of fibromyalgia. However, there’s truly nothing quite like regular exercise. Also, there are very few side effects with exercise. Sure, you’ll feel tired- but at least you’ll be able to sleep! Just make sure that whatever you do, you pay attention to what your body is telling you. If you feel that you need to stop- then stop. Don’t overwork yourself and trigger a fibromyalgia flare- then, you’ll be setback and have to start all over.

Take some time to discuss with your physician about incorporating exercise into your personal fibromyalgia treatment plan.

Interstellar’s Black Hole Imagery – ‘Blockbuster’ Science

Provided by Anna Carmichael, Cornell University

NSF-funded grad students, scientists publish research, play role in Interstellar’s black hole imagery

At this point, the blockbuster movie Interstellar has created such a stir that one would almost have to be inside a black hole not to know about it. And while the science fiction thriller may have taken some liberties with science to make its Hollywood plot work, the imagery comes straight from science–National Science Foundation (NSF)-funded science, in fact.

Similar in premise to many other science fiction films, something sets Interstellar apart: Many of the images are–for the most part–scientifically accurate, based on lensing calculations produced by Cornell University and California Institute of Technology scientists that show what black holes or wormholes look like.

“Gravity bends the path that light follows in space,” said Pedro Marronetti, an NSF program director for gravitational physics. “The stronger the gravitation, the more dramatic its effect.”

Four graduate students who work in NSF-funded, Cornell astronomy professor Saul Teukolsky’s group–Andy Bohn, François Hébert, William Throwe and Katherine Henriksson–as well as NSF-funded Caltech researchers Mark A. Scheel, Nicholas W. Taylor and undergraduate Darius Bunandar–have been doing related research and recently published their work about binary black holes on an online repository for scientific papers called ArXiv. The paper, “What Would a Binary Black Hole Merger Look Like?” immediately garnered media attention, including in Nature.

In the plot of Interstellar, Earth is dying; to save the human race, astronauts and scientists search for a new planet via a wormhole, essentially a shortcut through space to find a giant black hole at the other end.

Interstellar producers sought to make visual representations of the wormhole as accurate as possible. They worked closely with Kip Thorne, a theoretical physicist at Caltech and the film’s executive producer, who gave the special effects team the scientific equations to create a reasonable facsimile of a wormhole.

Thorne’s involvement in this gravitational lensing project led him to talk with the three Cornell grad students and their Caltech collaborators. The research of Bohn, Hébert and Throwe “on visualizing colliding black holes by gravitational lensing is very interesting and important,” Thorne said.

Wormholes do not actually exist in space, but black holes do, Throwe said, so the students created two short videos for Thorne, which showed what moving by a black hole in space would look like. It would be impossible to move through an actual black hole, they said, because the pull of gravity would tear a person apart.

“We know [interstellar travel through wormholes is] kind of crazy, but it makes a good story,” Throwe said.

Thorne used the students’ videos to help explain to the special effects team what kinds of information would be needed to make the visualizations believable.

“It’s a really small part of what they were doing, but it was really fun for us to do,” Bohn said.

While much is known about what a single black hole would look like in space, little was known about what two merging black holes would look like. New technology allowed the students to do that for their paper.

“The idea that you’re going to be one of the first people to look at what a merging pair of black holes would look like is a good incentive to keep going,” Hébert said.

Astronomers haven’t been able to visually observe black holes because nothing can escape from them, not even light or radiation. They can only be studied by noting their effects on nearby objects. That’s what makes this recent research so important–because it creates a new visualization.

The team is excited about their research and hopes it will inspire even more studies. “It will be a stepping-stone for us to look into more complicated problems,” Bohn said.

NSF’s Marronetti added, “It is very exciting to see young researchers’ work contributing to and represented in a blockbuster movie. I hope it will inspire more film directors to incorporate scientifically-based visualization in their movies.”

NSF’s Ivy Kupec contributed to this story.

Sick Of Ads? Crowdsource Your Favorite Websites Via Google

Chuck Bednar for redOrbit.com – Your Universe Online
If you’re tired of being inundated by banners and pop-ups when you visit your favorite websites, then you’ll be happy to hear that Google is launching a new project which will allow Internet users to pay to make those ads disappear.
It’s called Contributor, and it allows members to pay between $1 and $3 per month to support participating websites. Doing so will not only support the creators of those websites, but will cause a special “thank you” message to appear where there normally would be an advertisement.
According to Chris Velazco of Engadget, the program is currently in its beta stage, but websites such as Imgur, The Onion, Mashable and Urban Dictionary have already become involved in the program. Velazco called it “heartening” to see that Google, which earned $15 billion in ad revenue last quarter, was letting content creators choose another option.
Participation in Google Contributor is currently on an invitation-only basis and is currently limited to US residents, said GigaOM’s Mathew Ingram. Payments are handled through a user’s Google account, and the contribution is not divided evenly to all websites enrolled in the program, he explained. Instead, it is only triggered when a user visits a specific website, thus ensuring that readers only support the publishers whose websites they frequently visit.
“For publishers, the contributions are handled through their existing Google advertising accounts, with the search giant taking a small cut of the proceeds,” Ingram added, calling them an alternative to Google AdSense. “The company said it chose partners who didn’t have too much traffic (with the exception of Mashable, which gets 40 million uniques a month) because it wanted to start small and see how much the feature would get used.”
PC Magazine’s Mark Hachman said, there is currently no indication the websites would deny access to visitors who do not participate in Contributor. He noted that recent statistics indicate higher-end ads cost just $2.90 per 1,000 impressions, and considering that even the most dedicated readers likely aren’t visiting the same website 1,000 times per month, it appears as though the new program could be more lucrative to content producers.
“I think the bigger narrative is publishers are the lifeblood of the Web, and to have a healthy Web, you need to have publishers that are able to thrive and fund their content,” a Google spokeswoman told VentureBeat’s Jordan Novet in an interview about the new service Thursday. “We’ve made it a priority since the beginning of our business to provide different ways for them to do just that.”
“Could Google Contributor become a realistic alternative to a paywall for large news sites or even individual content creators? That remains to be seen, but Google deserves some credit for continuing to experiment with different forms of monetization,” Ingram said. “Some may see it as yet another attempt by the web giant to lock them into its platform, but others will likely be willing to try just about anything to find a way of generating income from their content.”

Most Excessive Drinkers Are Not Alcoholics

Chuck Bednar for redOrbit.com – Your Universe Online
Only 10 percent of men and women who consume too much alcohol are actually alcoholics or alcohol dependent, according to a new government study published Thursday in the US Centers for Disease Control and Prevention (CDC) journal Preventing Chronic Disease.
While excessive drinking can cause serious health problems and is responsible for an average of 88,000 deaths each year, Elahe Izadi of The Washington Post explains that the new study debunks the notion that most excessive drinkers are not alcohol dependent. The report is said to be one of the first national, multi-year investigations of alcoholism among excessive drinkers, she added.
The study, prepared by the CDC and the Substance Abuse and Mental Health Services Administration (SAMHSA), found that nearly one-third of all adults is an excessive drinker, meaning that they are binge drinkers (consuming four or more alcoholic beverages at a time for women, five or more for men), that they consume a certain amount of drinks per week (eight for women, 15 for men) or are alcohol-consuming minors or pregnant women.
Alcohol dependence, on the other hand, is described as a chronic medical condition typically including a current or past history of excessive alcohol consumption, a strong craving for alcohol, the continued consumption of such beverages despite repeated problems with drinking, and/or an inability to control alcohol consumption.

Image Above Credit CDC. Click here for the full infographic.

“This study shows that, contrary to popular opinion, most people who drink too much are not alcohol dependent or alcoholics,” Robert Brewer, head of the CDC’s alcohol program and one of the study authors, said in a statement. “It also emphasizes the importance of taking a comprehensive approach to reducing excessive drinking that includes evidence-based community strategies, screening and counseling in healthcare settings, and high-quality substance abuse treatment for those who need it.”
“A lot of people mistakenly assume that people who drink too much are alcoholics,” he added in an interview with Stephen Reinberg of HealthDay News. While Brewer said that some excessive drinkers are “self-medicating,” he added that “a lot of it is a reflection of the fact that we live in a society where people… have been led to believe that drinking, and often drinking a large amount, is part of having a good time. What we need to do is change the environment in which people make their drinking decisions.”
The message being sent by the CDC study isn’t that people who drink too much should not worry about their habits, Izadi explained, only that efforts to combat excessive drinking as a public health issue needs to focus on more than just alcoholism, a chronic medical condition. As Reinberg pointed out, excessive drinking can result in alcohol poisoning, as well as long-term effects such as breast cancer, liver disease and heart disease.
“Anybody who takes from this paper that excessive drinking is not dangerous unless you are dependent is simply not getting the message, which is that drinking too much is bad, period,” Brewer told Reuters, noting that it was important to quantify how many heavy drinkers were alcoholics to effectively treat both groups. “The great preponderance of people who are drinking too much are not candidates for specialized treatment but they can be helped in other ways.”

Atmospheric CO2 Levels Affected By Increased Crop Growth

Chuck Bednar for redOrbit.com – Your Universe Online

Decomposing crops could be responsible for one-fourth of the post-summer increase in atmospheric carbon dioxide levels, and this discovery could help scientists better understand and predict how the planet’s vegetation will react to warming temperatures, researchers from Boston University and elsewhere report in a new study.

Scientists have long known that atmospheric CO2 levels drop in the Northern Hemisphere every summer as plants inhale the substance, then climb again when they exhale following their growing season, but the exact reasons for this phenomenon have remained unclear. Now, however, they report in the journal Nature that agricultural production may play a vital role.

“In the Northern Hemisphere, there is a strong seasonal cycle of vegetation,” Mark Friedl, a professor in the Boston University (BU) Department of Earth and Environment and senior author of the new paper, said in a statement Wednesday. “Something is changing about this cycle; the ecosystems are becoming more productive, pulling in more atmospheric carbon during the summer and releasing more during the dormant period.”

While the majority of the annual change is attributed to the impact of higher temperatures being driven by global climate change – an impact which includes longer growing seasons, a more rapid uptake of carbon by crops, and the so-called greening of higher latitude regions with increasing amounts of vegetation – lead author and BU assistant professor Josh Gray explains that this is “not the whole story,” and that human factors need to be considered.

Friedl, Gray and their colleagues collected global production data for corn, wheat, rice and soybeans – four crops that together account for nearly two-thirds of all calories consumed worldwide. They discovered that the production of these crops in the Northern Hemisphere above the tropics has more than doubled since 1961, and that the increase growth effectively translates into one billion tons of carbon captured and released each year.

These crop areas are “ecosystems on steroids,” Gray said, explaining that while they only occupy approximately six percent of the vegetated land area in the Northern Hemisphere, they are responsible for at least 25 percent of the total increase in seasonal carbon exchange of atmospheric carbon dioxide. However, the authors noted that these seasonal effects are separate and distinct from the overall upward trend in CO2 that is driving climate change.

Image Above: The Keeling curve plots atmospheric carbon dioxide. The upward slope represents increases in CO2 levels caused by burning fossil fuels.

“A simple picture is that plants breathe. You can see the seasonal impact of this in the Keeling curve, the famous graph that shows atmospheric CO2 levels measured from a mountaintop in Hawaii since the late 1950s,” explained co-author Eric Kort, an assistant professor at the University of Michigan. “While it’s been continually increasing, it wiggles up and down a bit each year, and that’s this seasonal breathing of the biosphere.”

Those wiggles have been growing larger over the past five decades, increasing by as much as 50 percent at half at higher northern latitudes, and scientists have not fully understood why. Much of the change is believed to be caused by the natural system reacting to an altered climate, with changes in photosynthesis, respiration and expansion of woody vegetation potentially involved. Again, though, the authors said that mankind was also likely involved.

“This is another piece of evidence suggesting that when we (humans) do things at a large scale, we have the ability to greatly influence the composition of the atmosphere,” said co-author Chris Kucharik, a professor in the University of Wisconsin College of Agricultural and Life Sciences Department of Agronomy and the Nelson Institute for Environmental Studies.

“This study shows the power of modeling and data mining in addressing potential sources contributing to seasonal changes in carbon dioxide,” added Liz Blood, program director for the National Science Foundation’s MacroSystems Biology Program, which funded the recently-published study. “It points to the role of basic research in finding answers to complex problems.”

A separate study, also published this week in Nature, researchers at the University of Maryland (UMD) used a new atmospheric model developed at the university to determine that the intense farming practices of the so-called Green Revolution have been strong enough to boost the seasonal amplitude in atmospheric carbon dioxide to about 15 percent over the past five decades. The amplitude of season CO2 oscillation is increasing at a rate of 0.3 percent each year, they added.

“What we are seeing is the effect of the Green Revolution on Earth’s metabolism,” Ning Zeng, a UMD Atmospheric and Ocean Science Professor and the lead developer of VEGAS, a terrestrial carbon cycle model that factors in changes in 20th and 21st century farming practices, said in a statement. “Changes in the way we manage the land can literally alter the breathing of the biosphere.”

Unusual ‘Glow Worm’ Discovered In Peruvian Rainforest

Chuck Bednar for redOrbit.com – Your Universe Online
A mysterious, worm-like, glowing green larvae that lives in the Peruvian rainforest and uses its phosphorescence to lure unsuspecting prey into its waiting jaws might sound like something out of a horror story – but it’s very real.
These unusual glow worms were discovered by members of a rainforest expedition company near the Tambopata Research Center in Peru, and according to LiveScience staff writer Tia Ghose, it is believed to be the larval stage of a not-yet-identified species of beetle.
The creature was discovered by accident by wildlife photographer Jeff Cremer. While on a night hike in the rainforest of Tambopata, he reportedly noticed “several glowing green dots embedded within a dirt wall,” entomologist Aaron Pomerantz, who would accompany Cremer on a return journey to Peru this past October, wrote in a blog posted earlier this month.
Upon taking a closer look, it turned out that there were several dozen of the miniature insects, each of which glowed green in the night and were approximately 0.5 inches (1.2 centimeters) long. Cremer snapped some photos of the creatures and posted them online in the hopes that he would learn more about it.
While he was able to find out that the dots most likely belonged to some type of insect larvae, possibly a type of click beetle, little else was known about the creatures. So Cremer, Pomerantz and University of Florida graduate students Mike Bentley and Geoff Gallice made a return trip to discover more about this mysterious, glowing larvae.
According to Ghose, the researchers found that these glow worms eagerly consumed stick insects and termites in tests, and their style of attack was described as being reminiscent of the massive man-eating worms featured in the 1990 movie “Tremors” in that they live underground and “burst from the earth,” Pomerantz told the LiveScience reporter.
Click beetles, which belong to the family Elateridae, use a fast popping or “clicking” motion to escape predators, Pomerantz said. There are over 10,000 species of click beetles, approximately 200 of which are bioluminescent. While adults may feed on flowers and nectar, the larvae are most likely predatory, Ghose added.
“Bioluminescent animals usually glow to either lure in prey or to warn predators that they contain noxious chemicals. But the glowing also occasionally serves other purposes,” the LiveScience reporter said. In the case of the click-beetle larvae, Pomerantz said that it appears to glow to attract prey.
Pomerantz said that it was not certain at this point whether the creature first spotted by Cremer is an entirely new species or a subspecies of an existing type of beetle. However, the researchers are contacting experts in Brazil in order to find out, the entomologist noted. He also said that he and his colleagues plan to “investigate these amazing glow worms further to see what more we can learn while seeking to protect them and their environment.”
“At the end of the day, why should we care about these critters? Aside from the fact that they are downright bizarre and extraordinarily cool looking, the science behind bioluminescent click beetles is still lacking. What role do they play in the complex environment and ecosystem of the Amazon rainforest? Why exactly did they develop the ability to produce their own light, and how did this trait evolve?” he added. “These questions are far from answered, but perhaps a curious naturalist will come along and help to solve this, and many other, Amazonian mysteries.”

Workplace Authority Affects Men And Women Differently

Chuck Bednar for redOrbit.com – Your Universe Online
Females with workplace authority are often faced with resistance and negative stereotypes which can lead to depression
Men and women respond differently to being placed in a position of power at work, with female bosses experiencing an increase in symptoms of depression and their male counterparts experiencing a decrease in such symptoms when being able to hire and fire employees, scientists at the University of Texas at Austin claim in a new study.
According to BBC News health reporter Pippa Stephens, lead author Tetyana Pudrovska, an assistant professor in the Department of Sociology, and her colleagues interviewed 2,800 middle-aged men and women (1,300 males and 1,500 females) between 1993 and 2004. The subjects were between the ages of 54 and 64, and each of them graduated from high schools in Wisconsin, Stephens added.
Each participant was asked about workplace authority and the number of days they experienced symptoms of depression, including feeling melancholy and believing that one’s life was a failure, over the past week. They found that women who were placed in a position to hire/fire employees and influence pay, women were predicted to have a 9 percent increased rate of symptoms than female professionals who lacked such authority.
Conversely, men in such positions were predicted to have a 10 percent decreased rate of depression symptoms. The researchers said their work controlled for other factors that could cause depression, such as number of hours worked per week, whether people had flexible hours, and how often workers were checked by a supervisor.
Pudrovska and co-author Amelia Karraker from Iowa State University, who published their findings in the Journal of Health and Social Behaviour, report that the processes of gender stratification help create a workplace in which exercising job authority exposes female employees to interpersonal stressors which ultimately undermine the health benefits typically associated with job authority.
“What’s striking is that women with job authority in our study are advantaged in terms of most characteristics that are strong predictors of positive mental health,” Pudrovska explained in a statement Thursday. “These women have more education, higher incomes, more prestigious occupations, and higher levels of job satisfaction and autonomy than women without job authority. Yet, they have worse mental health than lower-status women.”
“Years of social science research suggests that women in authority positions deal with interpersonal tension, negative social interactions, negative stereotypes, prejudice, social isolation, as well as resistance from subordinates, colleagues, and superiors,” she added. “Women in authority positions are viewed as lacking the assertiveness and confidence of strong leaders. But when these women display such characteristics, they are judged negatively for being unfeminine. This contributes to chronic stress.”
Men placed in positions of authority, however, typically deal with fewer stressors because they do not have to overcome the workplace resistance and negative stereotypes often faced by their female counterparts, Pudrovska said. Instead, male authority figures are accepted as normative and legitimate, consistent with the status quo, and this in turn increases the power and effectiveness of the male authority figure, diminishing interpersonal conflict.
Dr. Ruth Sealy from the City University London Department of Psychology told BBC News that women were often “trapped” by the gendered ideal of what a good leader is, but when those same women adopted traditionally masculine behaviors as leaders, they are often criticized for being unfeminine.
She added that people naturally assume men are competent leaders, and women have had to traditionally work much harder to get to those positions, meaning that their “right” to such status “is continuously questioned.” Dr. Sealey concluded that it was essential for female leaders to be viewed as natural as male leaders.

Celiac Disease Researchers Say Oats May Be Bad As Well

Rayshell Clapper for redOrbit.com – Your Universe Online

Celiac disease is one of the main diseases associated with a gluten-free lifestyle. Of course, other health issues and autoimmune diseases require people to watch out for gluten as well, but celiac disease is the one that most have heard of and know about.

As defined by Celiac.com: “Celiac disease, also known as gluten intolerance, is a genetic disorder that affects at least 1 in 133 Americans.” The symptoms include serious gastrointestinal and health issues including vomiting, diarrhea, weight loss, malnutrition, and even nutrient deficiencies, just to name a few.

Currently no cure exists, so those who suffer from celiac disease must eat a gluten-free diet, meaning they cannot ingest wheat, barley or rye because these all contain gluten.

Seems easy, right? Well, it’s not.

These three grains are often found in hidden places – including soy sauce, spices, desserts and chips. On top of these, a recent Australian study found that a small percentage of those who have celiac disease also cannot ingest oats.

Most people who eat a gluten-free diet have no problems with oats, however, according to a statement: “Researchers from the Walter and Eliza Hall Institute, Monash University and US biotechnology company ImmusanT, led the 10-year study, published this month in the Journal of Autoimmunity. They revealed that oat consumption triggered an immune response in eight percent of the 73 participants with celiac disease.”

While that number doesn’t seem like much, knowing that oats may also trigger an autoimmune response could mean the difference between living a healthy life versus being unhealthy, unhappy and ill.

The study showed the relationship to celiac disease and other grains besides those with gluten. It also adds a greater understanding of celiac disease in general as well as informs those with the disease of what is safe to consume.

Knowing what is safe to consume is critical for many who suffer from gluten allergies. Since the current treatment for celiac disease relies solely on eating a gluten-free diet, one must know what will trigger symptoms in order to control them. Eating gluten-free is the only treatment option currently available, but there is good news. Scientists and doctors continue to search for treatments beyond just the special diet requirements.

In fact, in a joint PNAS study conducted by the University of Southern Denmark and the University of Oslo/ Oslo University Hospital, researchers have “managed to retrieve hitherto unknown details about what is happening in the body of a celiac patient who eats gluten.” This knowledge could ideally lead to the development of a drug treatment against the disease.

As the University of Southern Denmark explains: “When the immune system is activated, it produces antibodies that attack a particular enzyme in the body. Exactly how this interaction between antibodies and enzyme plays out has until now been unclear, but now the research team presents new details about how the antibodies are formed and behave as well as how the enzyme reacts to different stimuli.”

Between the Australian study’s findings on oats and the Danish/Norwegian study’s findings on antibodies and enzymes, this new information provides hope for the many who suffer from celiac disease.

For those who suffer from celiac disease, gluten-free is not a fad diet. It is mandatory for the body’s health, which is why it is so important to stay abreast of research and updated information on celiac disease and gluten-free diets.

2014 On Track To Be Hottest Year Ever, Thanks To Record-Breaking October Temps

Chuck Bednar for redOrbit.com – Your Universe Online
This October was the warmest ever recorded, National Oceanic and Atmospheric Administration (NOAA) scientists announced on Thursday, all but assuring that 2014 will be our planet’s hottest year in more than 100 years.
According to the NOAA October 2014 Global Analysis, the combined average temperature over global land and ocean surfaces for last month was 0.74 degrees Celsius (1.33 degrees Fahrenheit) above the 20th century average of 14.0 degrees Celsius (57.1 degrees Fahrenheit).
The global land surface temperature was 1.05 degrees Celsius (1.89 degrees Fahrenheit) above the 20th century average of 9.3 degrees Celsius (48.7 degrees Fahrenheit), making it the fifth highest for October on record. In addition, global sea surface temperatures were the highest ever recorded for the month, 0.62 degrees Celsius (1.12 degrees Fahrenheit) above the 20th century average of 15.9 degrees Celsius (60.6 degrees Fahrenheit).
In addition, NOAA officials said that the period of January through October of this year was the hottest stretch of its kind ever, said Mashable’s Andrew Freedman. It confirms data previously released by Japanese climate scientists and NASA, he added, and confirms that it would be next to impossible for this year to not set a new all-time annual temperature record.

Deke Arndt, chief of the climate monitoring division at the National Climatic Data Center (NCDC) in Asheville, North Carolina, told Freedman that in order for 2014 to fail to become the warmest year in recorded history, the months of November and December would each have to be colder than the 10th-warmest such months on record.
USA Today’s Doyle Rice added that this year is on pace to beat 2010 and 1998, the previous warmest years since such records were first kept back in 1880. One of the few places having a colder-than-average year is eastern North America, NOAA said, while five of the last six months (all but July) have established new monthly heat records.
“Last month also marked the 38th consecutive October – and the 356th month in a row overall – with a global temperature that was above average. The last below-average global temperature for October was in 1976,” Rice said. “NASA and Japan’s weather agency, which monitor global temperatures, also called it the hottest October on record. The trend extended to the USA, as well, which notched its fourth-warmest October, NOAA said.”
The USA Today reporter added that the Climate Prediction Center (CPC) is forecasting the above-average warmth trend will continue in December, although the southern plains are expected to see a cooler-than-average month. The best chance for above-average precipitation next month will be in the south, from California through the Carolinas, and the CPC said that there is a 60 percent chance that an El Niño will form over the next few months.
“A record warm 2014 could mark an end in a temporary slowdown in the rate of warming, which scientists think has been caused by a mix of manmade and natural factors, which has lasted for about the past 15 years. One of those factors was cooling ocean waters in parts of the Pacific, which appears to be reversing in a big way,” Freedman said, adding that the US has also just experienced its warmest 12-month period ever, breaking a record set last month.
“Globally, the Southern Hemisphere was record warm for October, while the Northern Hemisphere was third-warmest on record with a record high sea surface temperature,” he added. “Record warmth occurred across much of southern South America and much of southern and western Australia, NOAA said. Record warmth was also observed in parts of southern Europe, the West Coast of the U.S., where California is going to have its warmest year on record.”

Audio Clip Shows What Landing On A Comet Sounds Like

Chuck Bednar for redOrbit.com – Your Universe Online
It might just be a two second clip of what sounds like some rustling paper or a dull thud, but the recording of the Philae lander’s touchdown on Comet 67P/Churyumov-Gerasimenko (67P/C-G) released by the German Aerospace Center (DLR) on Thursday allows astronomy enthusiasts to hear just what making history sounds like.
The brief sound bite was captured by the Cometary Acoustic Surface Sounding Experiment (CASSE) instrument sensors, which are located in the feet at the base of the Philae’s three legs, DLR officials explained in a statement. The sensors were active as the lander made its historic first touchdown on November 12, the agency added.

While CNET’s Eric Mack admits that the recording “may not sound like much,” he emphasizes there is “a lot in the two-second recording for scientists to digest.” For instance, DLR scientists said that the Philae probe made initial contact with a soft layer several centimeters thick, then milliseconds later, it encountered a hard, possibly icy part of the comet’s surface.
According to DLR, CASSE first detected vibrations from the flywheel used to stabilize the flight. Upon its first contact with the comet’s surface, the lander rebounded off of the surface because the harpoons designed to anchor it as it touched down failed to deploy. Scientists from the German space agency said that, based on their data, Philae did not immediately return to the comet after it bounced off 67P/C-G’s surface.
Philae landed a total of three times, and after it finally came to rest, it immediately began making scientific measurements. Afterwards, CASSE transmitted and received vibrations from the lander’s feet in order to determine the properties of the comet’s surface, and was also able to detect vibrations as the Multi-Purpose Sensors for Surface and Subsurface Science (MUPUS) tool attempted to hammer a probe into the ground.
While Rachel Feltman of The Washington Post noted that data regarding the second post-bounce landing only confirmed what mission scientists already knew, Philae project scientist Klaus Seidensticker said that he and his DLR colleagues were initially worried their instruments would be unable to collect any data from the comet. Now, however, he said they have “much more data than I had hoped for.”
Rosetta begins science phase
Meanwhile, in related news, ESA announced that the Rosetta orbiter had continued into its own full-science phase now that Philae’s part of the mission has come to a close. This week, the spacecraft has performed a series of maneuvers, using its thrusters to optimize its orbit around 67P/C-G for its 11 onboard scientific instruments, the agency noted.
Additional burns were planned for Wednesday, November 22 and November 26 in order to further adjust the orbit to bring it to approximately 30 kilometers above the comet, explained Spacecraft Operations Manager Sylvain Lodiot. Starting next week, Rosetta’s orbit will be altered based on the needs of the scientific sensors, and on December 3, it will move down to a height of 20 km for about 10 days, after which time it will return to 30 km.
“The desire is to place the spacecraft as close as feasible to the comet before the activity becomes too high to maintain closed orbits,” said Laurence O’Rourke of the Rosetta Science Operations Centre near Madrid, Spain. “This 20 km orbit will be used by the science teams to map large parts of the nucleus at high resolution and to collect gas, dust and plasma at increasing activity.”
“Science will now take front seat in this great mission. It’s why we are there in the first place!” added Rosetta Project Scientist Matt Taylor. “The science teams have been working intensively over the last number of years with the science operations centre to prepare the dual planning for this phase.”
Rosetta, which launched in March 2004 and spent a total of 957 days in a hibernation-like state while traveling through space before being reactivated, is scheduled to spend the next several months analyzing the comet. It will maintain orbit around the comet through the end of 2015, performing ongoing analysis of the comet as it approaches the sun and then moves further out into deep space.

Scientists Get To The Heart Of Fool’s Gold As A Solar Material

Provided by David Tenenbaum, University of Wisconsin-Madison

As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into electricity.

Theoretically, iron pyrite — a cheap compound that makes a common mineral known as fool’s gold — could do the job, but when it works at all, the conversion efficiency remains frustratingly low. Now, a University of Wisconsin-Madison research team explains why that is, in a discovery that suggests how improvements in this promising material could lead to inexpensive yet efficient solar cells.

“We think we now understand why pyrite hasn’t worked,” says chemistry Professor Song Jin, “and that provides the hope, based on our understanding, for figuring out how to make it work. This could be even more difficult, but exciting and rewarding.”

Although most commercial photovoltaic cells nowadays are based on silicon, the light-collecting film must be relatively thick and pure, which makes the production process costly and energy-intensive, says Jin.

A film of iron pyrite — a compound built of iron and sulfur atoms — could be 1,000 times thinner than silicon and still efficiently absorb sunlight.

Like silicon, iron and sulfur are common elements in the Earth’s crust, so solar cells made of iron pyrite could have a significant material cost advantage in large scale deployment. In fact, previous research that balanced factors like theoretical efficiency, materials availability, and extraction cost put iron pyrite at the top of the list of candidates for low-cost and large-scale photovoltaic materials.

In the current online edition of the Journal of the American Chemical Society, Jin and first author Miguel Cabán-Acevedo, a chemistry Ph.D. student, together with other scientists at UW-Madison, explain how they identified defects in the body of the iron pyrite material as the source of inefficiency. The research was supported by the U.S. Department of Energy.

In a photovoltaic material, absorption of sunlight creates oppositely charged carriers, called electrons and holes, that must be separated in order for sunlight to be converted to electricity. The efficiency of a photovoltaic solar cell can be judged by three parameters, Jin says, and the solar cells made of pyrite were almost totally deficient in one: voltage. Without a voltage, a cell cannot produce any power, he points out. Yet based on its essential parameters, iron pyrite should be a reasonably good solar material. “We wanted to know, why is the photovoltage so low,” Jin says.

“We did a lot of different measurements and studies to look comprehensively at the problem,” says Cabán-Acevedo, “and we think we have fully and definitively shown why pyrite, as a solar material, has not been efficient.”

In exploring why pyrite was practically unable to make photovoltaic electricity, many researchers have looked at the surface of the crystals, but Cabán-Acevedo and Jin also looked inside. “If you think of this as a body, many have focused on the skin, but we also looked at the heart,” says Cabán-Acevedo, “and we think the major problems lie inside, although there are also problems on the skin.”

The internal problems, called “bulk defects,” occur when a sulfur atom is missing from its expected place in the crystal structure. These defects are intrinsic to the material properties of iron pyrite and are present even in ultra-pure crystals. Their presence in large numbers eventually leads to the lack of photovoltage for solar cells based on iron pyrite crystals.

Science advances by comprehending causes, Jin says. “Our message is that now we understand why pyrite does not work. If you don’t understand something, you must try to solve it by trial and error. Once you understand it, you can use rational design to overcome the obstacle. You don’t have to stumble around in the dark.”

Alcoholism Found To Harm Parts Of The Brain Governing Self-Control

Chuck Bednar for redOrbit.com – Your Universe Online
Regularly drinking too much alcohol can cause measurable damage to the brain’s frontal and superior white matter tracts, according to new research appearing in the December 2014 online-only edition of the journal Alcoholism: Clinical & Experimental Research.
In the study, corresponding author Catherine Brawn Fortier, a neuropsychologist and researcher at the VA Boston Healthcare System and an assistant professor at Harvard Medical School, and her colleagues used high-resolution structural magnetic resonance (MR) scans to determine the brain’s regional vulnerability to chronic alcohol abuse.
The brain scans revealed that the excessive alcohol consumption caused particular damage to the white matter tracts in the frontal lobes, the part of the brain that helps govern behaviors such as self-control, planning, and judgment, reasoning and learning new behaviors, Madlen Davies of The Daily Mail explained.
“Damaging the white tracts in this area interferes with impulse control, which is needed to achieve and maintain abstinence from an addictive substance like alcohol,” Davies noted. As such, Fortier and her colleagues believe that their research may help explain the reason that it is so difficult for alcoholics to kick the drinking habit.
“The idea that alcohol affects the brain has been established for decades,” Fortier added in a statement. “Before advances in neuroimaging technology, the degree to which alcohol affects the brain across different levels of alcohol use, and how it may interact with other health factors, could only be inferred from behavior and through post-mortem studies. We now can use neuroimaging techniques to see, in vivo, that alcohol has wide ranging effects across the entire brain that contribute to a wide range of changes in psychological abilities and intellectual functions.”
The authors noted that the human brain is usually divided into two broad types of tissues – gray matter and white matter. Gray matter, or the cortex consisting of neurons, contains the critical cells which support brain function, while white matter is the connection among large groups of those cells. Alcohol affects both types of matters, but has the greatest impact on the frontal lobes.
“These brain areas are critical to learning new information and, even more importantly, in self-regulation, impulse control, and the modification of all complicated human behaviors. In other words, the very parts of the brain that may be most important for controlling problem drinking are damaged by alcohol, and the more alcohol consumed, the greater the damage,” Fortier said.
The frontal white matter tracts connect the frontal lobes to the rest of the brain, she added, and the frontal cortex “is the integration center for all other parts of the brain that are important to behavior and cognitive function. These pathways support self-monitoring, planning, judgment, and reasoning. Frontal pathways also allow flexibility in learning and memory, and allow us to change and learn new patterns of behavior. Most importantly, frontal pathways underlie impulse control, which is essential to achieve and maintain abstinence.”
She and her colleagues assessed both global and white matter microstructure in two groups using diffusion MR measures of fractional anisotropy (FA) to create a three-dimensional measurement of white matter tissue. Of the subjects, 31 were abstinent alcoholics (20 men, 11 women) with an average of 25 years of abuse and approximately five years of sobriety, while the other 20 were nonalcoholic control participants (13 men, 7 women).
“There were two key findings to our study,” Fortier explained. “First, recovered alcoholics showed reductions in white matter pathways across the entire brain as compared to healthy light drinkers. This means that the pathways that allow the different parts of their brains to communicate efficiently and effectively are disrupted by alcoholism. Second, the effect of alcohol on the brain appears to be dose specific.”
“Pathology is often thought of as occurring as an all-or-none phenomenon – you either have brain damage or you don’t, similar to a stroke. Alcohol, however, is more like sunburn,” she added. “Our study shows that the damage occurs as a function of quantity and exposure; the more you drink, the greater the damage to key structures of the brain… so tragically, it appears that some of the areas of the brain that are most effected by alcohol are important for self-control and judgment, the very things needed to recover from misuse of alcohol.”

FTC Claims Two Bogus Tech Support Firms Conned Customers Out Of $120M

Chuck Bednar for redOrbit.com – Your Universe Online
At the behest of the US Federal Trade Commission (FTC), a federal court has ordered a pair of telemarketing firms to be shut down, accusing them of scamming customers out of $120 million by providing bogus technical support.
According to Hayley Tsukayama of The Washington Post, the FTC’s action comes against two different Florida-based companies: one against the firm that makes and markets PC Cleaner software, and another doing business as Boost Software Inc. and OMG Tech Help.
In a statement, the FTC said that it had received complaints dating back to at least 2012 accusing the defendants of using software to trick consumers into believing that there were problems with their computers, then subjecting those individuals to “high-pressure deceptive sales pitches” for services to fix those non-existent problems.
“These operations prey on consumers’ lack of technical knowledge with deceptive pitches and high-pressure tactics to sell useless software and services to the tune of millions of dollars,” said Jessica Rich, director of the FTC’s Bureau of Consumer Protection “There’s no excuse for it, and we are pleased the court has taken steps to temporarily shut down these scams while our lawsuit proceeds.”
The court order places a temporary freeze on the defendants’ assets, and orders that both firms be placed under the control of a court-appointed receiver, the Commission said. The cases mark the third in a series of actions brought by against purveyors of computer repair schemes, following a law enforcement sweep of cases in 2011 and action brought against a New York-based scammer earlier this year, FTC officials added.
“Offering false technical support is an all-too common way that scammers prey on computer users – often older computer users – who fear their computers have been infected with malicious software,” Tsukayama explained. “In a standard scam, criminals will call and claim to have found a virus on a person’s computer and ‘prove’ it to the call recipients by instructing them to navigate to harmless but little-used menus that they claim are evidence of a virus. From there, scammers then convince users to pay them to remove the ‘virus.’”
The scams perpetrated by these companies were similar in nature, Reuters reporter Diane Bartz noted, involving salespeople who called homes to convince people to download and run a so-called free computer security scan. That scan would typically discover several non-existent issues, and the caller would urge customers to purchase software for $29 or $49 – though the FTC said that in some cases, customers were scammed for tech support services of up to $500.
According to Jon Brodkin of Ars Technica, the FTC and the State of Florida are accusing both companies of violating the Telemarketing Sales Rule of the FTC Act and the Florida Deceptive and Unfair Trade Practices Act. The Commission is seeking permanent injunctions to prevent future violations, as well as refunds for all victims of the schemes and reimbursement for the government’s cost of bringing the actions.
The defendants in the first case include PC Cleaner Inc.; Netcom3 Global Inc.; Netcom3 Inc., also doing business as Netcom3 Software Inc.; and Cashier Myricks, Jr. The telemarketing defendants include Inbound Call Experts LLC; Advanced Tech Supportco. LLC; PC Vitalware LLC; Super PC Support LLC; Robert D. Deignan, Paul M. Herdsman, and Justin M. Wright.
The defendants in the second case include Boost Software Inc. and Amit Mehta, and the telemarketing defendants include Vast Tech Support LLC, also doing business as OMG Tech Help, OMG Total Protection, OMG Back Up, downloadsoftware.com, and softwaresupport.com; OMG Tech Help LLC; Success Capital LLC; Jon Paul Holdings LLC; Elliot Loewenstern; Jon-Paul Vasta; and Mark Donahue.
Rich McCormick of The Verge reported that Boost Software’s website was still in operation as of late Wednesday night, promoting several software products claiming that they can keep your computers safe. One of those products was PC Healthboost, the company said can speed up your machine by “216 percent,” he added, and the company claimed to be “the 646th fastest growing company in the US,” with 2013 revenues of $11.5 million.

Comparing The Genomes Of Mice And Humans To Aid Clinical Research

Chuck Bednar for redOrbit.com – Your Universe Online
An international research consortium investigating the functional genome of the mouse have managed to map the creature’s so-called “mission control” centers, and found new clues as to why certain processes and systems in the rodents prevent the results of mouse studies from being successfully replicated in humans.
Members of the Mouse ENCODE project, a project designed to complement the National Human Genome Research Institute’s (NHGRI) Encyclopedia of DNA Elements (ENCODE) program, were able to produce an exhaustive description of the functional genome elements of mice, and compared that information to the human genome. Their findings produced similarities between the two mammals, as well as some significant differences.
ENCODE, which began in 2003, analyzed specific components in the human genome responsible for gene expression, or the process of coding for proteins that carry out a cell’s function. The Mouse ENCODE study looked at 100 mouse cell types and tissues to annotate the regulatory elements of the mouse genome and compared them to the human genome – useful research, since mice are so often used as model organisms in clinical studies.
According to the National Institutes of Health (NIH), which oversees the NHGRI, the researchers reported their findings in four separate studies published in the journal Nature and other prominent scientific journals. In those papers, the authors examined the genetic and biochemical programs involved in regulating both mouse and human genomes, finding that the systems responsible for controlling gene activity in each have many similarities that have been conserved through the evolutionary process.
Their findings could provide new insight into genetic regulation and other systems essential to mammalian biology, the NIH said. Furthermore, their work could provide new information to determine in which cases the mouse will continue to be an appropriate model for studies involving the effect of drugs and disease on humans, as well as help explain some of the limitations of this model and why the results of such studies sometimes fail to translate to people.
“The mouse has long been a mainstay of biological research models,” said NHGRI Director Dr. Eric Green. “These results provide a wealth of information about how the mouse genome works, and a foundation on which scientists can build to further understand both mouse and human biology. The collection of mouse ENCODE data is a tremendously useful resource for the research community.”
“This is the first systematic comparison of the mouse and human at the genomic level,” added Dr. Bing Ren, a professor of cellular and molecular medicine at University of California, San Diego (UCSD) and co-senior author of the Consortium’s primary Nature study. “We have known that the mouse was mostly a good model for humans… [and] this allows us to study human disease by studying those aspects of mouse biology that reflect human biology.”
Among the discoveries made during the course of the research was the discovery as to why the immune system, metabolism and stress response of mice are so different from humans, the Centre for Genome Regulation (CGR), one of the institutions involved in the project, explained. They compared various processes involved in gene expression, including gene transcription and chromatin modification, and repeated those investigations in various different tissues and cell types from both mice and humans.
“Our lab took part in analyzing the group of RNA or transcriptome, that results from transcription, the process by which the instructions in the genes are read,” said Alessandra Breschi, a CGR researcher and one of the first co-authors of the main study. “We have discovered that human and mice transcriptome contains both preserved and divergent elements. Surprisingly we have found that the differences seem bigger between species rather than between fabrics when initially we thought that the gene activity in the same kinds of tissues would be similar.”
The Mouse ENCODE research revealed there is a common “language” used by cells at the molecular level that is at the same time immensely flexible and has varied greatly during the evolutionary process. For instance, by using electrical circuits as an analogy, you would find that they all have the same parts (cables, plugs, switches, etc.), that that circuits can differ greatly if those pieces are combined in different ways. Similarly, while the basic mechanisms covering both mice and humans are similar, there are obvious differences between the two creatures.
“Most of the differences between mice and humans come from regulation of gene activity, not from genes themselves,” explained Dr. Michael Beer, an assistant professor of biomedical engineering at the Johns Hopkins University School of Medicine and a member of the research team. “Because mice are an important model for human biology, we have to understand these differences to better interpret our results.”
Similarly, the researchers compared 15 tissue types between humans and mice, and found that on the whole gene expression profiles in mouse tissues are more similar to one another than to their human counterparts – in other words, in terms of how genes are expressed, a mouse liver is more similar to a mouse kidney than to a human liver. However, some gene regions were found to transfer from mouse to human more easily than others.
“The mouse is the premier organism for modeling human disease and many other things – a lot of what we know about human biology does come from the mouse,” said Dr. Michael Snyder, professor and chair of genetics at Stanford University. “The genome is what controls everything at some level. We’re interested in trying to understand the basic processes about how they’re similar or different across some of the most important species people are studying. It’s just fundamentally important.”

Mozilla announced on Wednesday that it was ending its 10-year relationship with Google, and had signed a five-year deal to make Yahoo the default search-engine provider for its Firefox web browser in the US.
“Google has been the Firefox global search default since 2004. Our agreement came up for renewal this year, and we took this as an opportunity to review our competitive strategy and explore our options,” Mozilla CEO Chris Beard wrote in a blog post.
“In evaluating our search partnerships, our primary consideration was to ensure our strategy aligned with our values of choice and independence, and positions us to innovate and advance our mission in ways that best serve our users and the Web. In the end… one strategy stood out from the rest,” he added, explaining that Mozilla was “ending our practice of having a single global default search provider” in favor of a country-by-country approach.
In addition to switching to Yahoo in the US, Mozilla also announced that it would be using Yandex in Russia and Baidu in China, said Peter Bright of Ars Technica. As part of its new contract with Yahoo, the search engine will begin honoring the Do Not Track feature used by Firefox (which will limit the search portal’s ability to monitor user activity) and will unveil a new search interface for the web browser starting in December.
Bright reported that financial terms of the deal between Mozilla and Yahoo were not revealed. Over the course of its 10 year relationship with Google, the Mountain View, California-based company paid an estimated $100 million to be the default Firefox search engine – a sum which Bright said represented up to 85 percent of Mozilla’s total income.
Yahoo CEO Marissa Mayer released a statement calling the new deal “the most significant partnership for Yahoo in five years” stating the company was “proud that Mozilla has chosen us as their long-term partner in search.” Mayer also called Mozilla “an inspirational industry leader who puts users first” and that their new Firefox interface would provide “a clean, modern, and immersive search experience.”
As for the impact the new partnership will have on Google, CNET’s Stephen Shankland said that, even though Firefox has “millions of users who perform about 100 billion searches a year” and “is a major source of the search traffic that’s Google’s bread and butter,” the company now has its own web browser, Chrome, and does not need to share search-ad revenue earned through that browser with any other company.
Beard confirmed that Firefox users will still be able to switch to other search engines, and that Google, Bing, DuckDuckGo, eBay, Amazon, Twitter and Wikipedia would be built-in alternatives. In Russia, Yandex Search will be the default and Google, DuckDuckGo, OZON.ru, Price.ru, Mail.ru, and Wikipedia will be alternatives, while in China, Baidu will be the default, while Google, Bing, Youdao, Taobao and other local options will also be available.
“Our new search strategy doubles down on our commitment to make Firefox a browser for everyone. We believe it will empower more people, in more places with more choice and opportunity to innovate and ultimately put even more people in control over their lives online,” the Mozilla CEO said. “Being non-profit lets us make different choices. Choices that keep the Web open, everywhere and independent. We think today is a big step in that direction.”

Texting Affects Your Spine And Posture

Chuck Bednar for redOrbit.com – Your Universe Online
Frequently hunching over to read or write text messages could be damaging your spine, according to a new Surgical Technology International study that compares looking down at a cell phone to placing a 60-pound weight on your neck.
In the new study, author Dr. Kenneth K. Hansraj, Chief of Spine Surgery at New York Spine Surgery & Rehabilitation Medicine, set out to explain that people were demonstrating poor posture while using their mobile devices. To illustrate his point, he assessed the forces incrementally experienced by the cervical spine as the head is tilted forward while texting.
Dr. Hansraj built a realistic model of the cervical spine in a finite element assessment package known as Cosmosworks. He then made calculations for both the head and neck in which the forces of bending down to text were extracted in Newtons and then converted to pounds. The doctor said that the average weight was 60 Newtons (13.2 pounds or 6 kilograms), with the center of mass was located 16cm above the C7 vertebrae.

“The weight seen by the spine dramatically increases when flexing the head forward at varying degrees,” he wrote. “An adult head weighs 10 to 12 pounds in the neutral position. As the head tilts forward the forces seen by the neck surges to 27 pounds at 15 degrees, 40 pounds at 30 degrees, 49 pounds at 45 degrees and 60 pounds at 60 degrees. At 90 degrees the model prediction was not reliable.”
Nielsen claims that the average American spends about one hour per day on their smartphones, explained Olga Khazan of The Atlantic. Dr. Hansraj, however, wrote in his report that people spend an average of two to four hours each day with their heads tilted forward reading and texting using smartphones and other mobile devices.
Based on his figures, that means the average individual spends up to 1,400 hours per year placing extra stress on the cervical spine, and that a high school student could potentially spend an extra 5,000 hours in poor posture positions. Unless people train themselves to stare straight ahead into their mobile device without bending their spines, he said that the cumulative stress could “lead to early wear, tear, degeneration, and possibly surgeries.”
Dr. Hansraj, who said he believes that his is the first study to analyze the stresses in the neck region that result from incrementally moving the head forward, noted that it was “nearly impossible” to avoid using the technology that causes these problems. However, he also suggested that individuals should “make an effort to look at their phones with a neutral spine and to avoid spending hours each day hunched over.”
However, as NY Magazine’s Melissa Dahl noted, “there’s a psychological component here, too. Hunching over your phone creates a closed-off posture that’s kind of the opposite of power posing, the expansive body positioning (shoulders back, chest puffed out) that social psychologists say makes us feel and act more confident. So, for the sake of your spine and your self-confidence, when you’re staring at your smartphone, try to un-hunch.”
In January of this year, another study by University of Queensland researchers showed that texting while walking “causes us to slow the pace of our walk, swerve slightly and move more robotically.”
“If you’re walking along and texting, the key issue is that you think you’re walking in a straight line. But you’re actually not,” said study author Siobhan Schabrun. “You can end up having an accident.”

Observing Physics Of Cooling Liquid Metals

Provided by Laura Niles, NASA

Sure, it’s easy to say that research in microgravity is cool, but the European Space Agency’s (ESA) new electromagnetic levitator brings new meaning to the word. A new ESA facility aboard the International Space Station will serve as a furnace capable of levitating and heating metals up to 3,632 degrees Fahrenheit. Having such a facility in microgravity will allow scientists to observe fundamental physical processes that occur as liquid metals cool.

ESA’s final Automated Transfer Vehicle (ATV-5) mission to the space station delivered the Materials Science Laboratory Electromagnetic Levitator (MSL-EML) and its first batch of new materials science investigations. EML research will provide insight into how liquid metals cool without the influence of gravity or the mold that encases the cooling metals.

“In all of the experiments, microgravity enables access to conditions and measurements that are difficult or impossible on the ground,” explained Robert Hyers, Ph.D., professor of Mechanical Engineering at the University of Massachusetts, Amherst, and co-investigator of EML Thermolab.

Most metals used in our daily lives are alloys, mixtures of two or more metals or metal and another material. A well-known alloy is stainless steel, used to make utensils and kitchen appliances, among other items.

The traditional process of casting alloys includes heating, shaping and then rapidly cooling them to create a specific form. Rapid cooling hardens the alloys into a solid structure while also forming their microstructure. Solid alloys form mixed structures composed of crystals that make up their microstructure, which impacts the characteristics of strength, flexibility and resistance to fatigue.

EML processes one sample at a time. Each sample is suspended in weightlessness and supported by magnetic repulsion, the force that pushes like ends of magnets apart. The sample is heated to liquefaction. No containers are used to hold the metals during experiments in the EML so measurements of the heated metals can be taken in purest form. In contrast, ground studies of alloys must use containers to hold the heated liquid forms.

One of the studies in this first batch of EML investigations is Thermolab. This collaboration involves 15 countries on three continents and is led by Professor Hans Fecht at Ulm University in Germany. Thermolab includes a number of samples with multiple experiments per sample occurring during the next two to five years.

“The basic goal is to provide the fundamental information needed to use modern computers to accelerate the rate of innovation in manufacturing and materials engineering,” said Hyers.

To accomplish that goal, Thermolab will investigate temperatures and physical properties of industrial alloys in the liquid phase. This helps scientists improve models of industrial casting and solidification processes for materials used in the aerospace, automotive and consumer electronics industries.

These new EML investigations have the potential to impact how scientists develop lighter, higher-performing alloys for use both on Earth and in space travel. This first batch of at least seven investigations, including Thermolab, share samples to be processed in MSL-EML and the resulting data. Several of the studies will be conducted during 2015.

“Space exploration benefits even more from the better understanding of materials processing,” explained Hyers. “3-D printing is getting a lot of current attention, including for the production of low-volume, complex parts like those used in rockets or potentially new parts for the space station. Making those parts in microgravity will require the kinds of models that Thermolab enables.”

Although the metals heated in the EML during these studies might find this research to be red hot, scientists who study these materials and the people who may one day benefit from the results might say levitating liquefied metals in space is pretty cool.

Iguanas Breathe Just Like Birds, Scientists Find

Lisa Powers for redOrbit.com – Your Universe Online

Scientists have known for years that birds breathe differently from mammals, exhibiting a unidirectional airflow in their lungs. This was thought to occur only in the class Aves (birds), and scientists hypothesized it was due to the high energy demand required for flying.

But science is a dynamic process and thanks to new research, which has found that iguanas also breathe in a unidirectional manner, we are reminded of just how similar birds and reptiles actually are.

Published in the Proceedings of the National Academy of Science, the study was performed by Colleen Farmer and her colleagues at the University of Utah—following on the heels of several other reptile studies produced by the team. In 2010, they also determined that alligators exhibited a unidirectional air flow.

The findings of the 2010 study inspired Farmer and her colleagues to investigate airflow in other groups of reptiles. While alligators are reptiles, they are not lizards. Instead, they belong to the group classified as crocodilians. First focusing on monitors, a primitive and ancient lineage of lizards, they found the same airflow pattern as in the crocodilians.

Sometimes different groups of animals develop similar structures, features or characteristics because of pressures from the environment. This is called convergent evolution. But sometimes, the code is already programmed into the genes and passed down from the ancestors. In examining the two different reptiles (crocodiles and monitors) and comparing them with birds, this was the big question: Were these similarities in breathing pattern convergent evolution, or simply a genetic trait passed down from a common ancestor?

Scientific evidence shows the first reptiles appeared around 300 million years ago. Dinosaurs evolved over the next 120 million years and then were mostly wiped out during the Cretaceous–Paleogene (K–Pg) extinction event around 65 million years ago, except for a few feathered dinosaurs that have evolved into our present day birds. In a 1998 paper published in Nature, the authors noted, “The fossils of two new species of dinosaur have been discovered in China – dinosaurs with feathers. These creatures effectively close the debate on whether or not birds and dinosaurs share a close evolutionary heritage. The answer is a resounding ‘yes’.”

While we’re excited this new research adds to the growing reptiles-and-birds-descended-from-a-common-ancestor evidence, we’ve been convinced of this for like two decades now, and wonder where the rest of the science world has been. Did they not see Jurassic Park?

Mysterious Fireball Lights Up Russian Sky, Baffles Experts

Christopher Pilny for redOrbit.com – Your Universe Online

Since being published on YouTube on Monday, a dashcam video showing a fireball lighting up the Russian sky has been causing quite a debate amongst experts–namely: What the hell is it?

Thus far, we’ve seen an array of theories: ammunitions explosion, falling satellite, meteor, small nuclear device, and our personal favorite, “a mass build-up of Mountain Dew and Doritos being suddenly released.” Because, well, who hasn’t been there?

But the best (and most logical) explanation we’ve seen has come from astronomer and author Phil Plait in an article he wrote for Slate.

“The first obvious guess is that this was a bolide,” he writes, “a fireball caused by a chunk of debris entering our atmosphere from space at high speed. These happen pretty often.”

Plait goes on to admit that the color and trajectory are off if it is indeed space junk, though. Bolides often burn white, green or blue, and they generally don’t sit still, which is what the fireball seems to be doing in the video. But that, Plait concedes, could just be because it was flying right at the photographer–something to keep in mind if you’re ever filming burning fireballs in the future.

Other video seems to show the object breaking up as it enters the atmosphere, reinforcing the theory that it is, indeed, just space junk. But Plait isn’t certain–just like the rest of the world.

The greater question, at least for us, doesn’t involve what it was, or why meteors/explosions always seem to end up over Russia, but why so many Russians feel the need for dashcams? Do they enjoy, at a cultural level, looking out over their dashboards and through their windshields for hours on end? Are Russian automakers required by law to build them into every vehicle? Or do Russians simply enjoy watching COPS and want to get in on the action?

Who knows? But we’re interested in any and all insight.

Editor’s Note: Thanks to Wired (and the redOrbit social media staff) for this explanation of Russian dashcam prevalence.

Biochemists Build Largest Synthetic Molecular “Cage” Ever

Brett Smith for redOrbit.com – Your Universe Online

Biochemists at UCLA have been working to develop a ‘cage-like’ structure made of proteins to deliver materials into cells, and on Monday, the scientists announced they have successfully developed the largest-ever self-assembling molecular cage.

According to a report from the team published in Nature Chemistry, the tiny structure is made of 24 copies of a single protein and has large openings that allow for easy entrance and exit.

UCLA professor Todd Yeates has been trying to build a self-assembling protein structure since first publishing research on them on 2001. Yeates and his peers created a self-assembling cage produced from 12 pieces that fit together like pieces of a jigsaw puzzle.

“This is the first decisive demonstration of an approach that can be used to combine protein molecules together to create a whole array of nanoscale materials,” Yeates said back in 2012.

More recently, the team has been able to build a molecular cage with 24 parts, according to their Nature Chemistry report. They are presently trying to layout a molecular cage with 60 sections. Constructing ever-larger cages presented new scientific difficulties, but the even bigger sizes could carry a lot more “cargo,” the study team said.

“If you just connect two random proteins together, you expect to get an irregular network,” Yeates said in discussing his 12-piece cage. “In order to control the geometry, the idea was to make a rigid link holding the two proteins in place as if they were parts of a toy puzzle.”

In theory, the structures being built by the UCLA scientists should be able to deliver some kind of cargo to the interior of a cell. However, the current structures are far too porous to pull that off.

“But the design principles for making a cage that is more closed would be the same,” Yeates said.

The UCLA scientist also noted that his team could make a cage that is less secure, so when it enters a cell, it would discharge its medicine, nutrients or other cargo.

“In principle, it would be possible to attach a recognition sequence for cancer cells on the outside of the cage, with a toxin or some other ‘magic bullet’ contained inside,” Yeates said in 2012. “That way, the drug could be delivered directly to certain targets like tumor cells.”

Yeates also mentioned that his lab’s technique could also result in the creation of artificial vaccines that would mirror what a cell sees when it’s contaminated by a virus. This new kind of vaccine would trigger a solid reaction from the immune system and possibly supply better defense against diseases than conventional vaccines.

So far, the UCLA team has only used bacterial proteins to build their structures and has expressed a desire to eventually start using human proteins.

“Our first challenge will be repeating these kinds of designs with molecules that are less likely to generate a host immune response,” Yeates said. “Generally, we want to use proteins that look like human proteins so the body does not recognize them as foreign.”

Did Russia Secretly Launch A Satellite-Killer Into Orbit?

Chuck Bednar for redOrbit.com – Your Universe Online
A mysterious object launched by Russia last Christmas is being tracked by western space agencies and other officials, and there are concerns that the probe could be part of a program to capture or destroy other satellites.
According to Sam Jones, Defense and Security Editor for Financial Times, amateur astronomers and satellite-trackers all across the globe have been following the unusual maneuvers of the object, which has officially been designated Object 2014-28E. It is also being tracked by the US military under NORAD designation 39765.
Experts had originally dismissed the object as space debris that was carried into orbit as part of a Russian launch back in May. However, BBC News online science editor Paul Rincon reported that Roscosmos officials told the UN that the May launch contained four satellites, not the customary three, leading to concerns that Object 2014-28E may be a revived Cold War-era project.
The object, which Rincon said is known as the Kosmos 2499 satellite, could be part of a Russian program to test a probe capable of chasing down orbiting spacecraft, possibly to repair or disable them. Witnesses have seen Kosmos 2499 perform a series of unusual maneuvers in space that changed its orbit – maneuvers which culminated on November 9 with a close approach to part of the rocket used to originally place it in orbit, he added.
Jones noted that the purpose of this object is “unknown” and “could be civilian: a project to hoover up space junk, for example. Or a vehicle to repair or refuel existing satellites. But interest has been piqued because Russia did not declare its launch – and by the object’s peculiar, and very active, precision movements across the skies.”
The country had previously been working on an anti-satellite weaponry program known as “Istrebitel Sputnikov” or “satellite killer,” he added, and while work on the project was officially “mothballed… after the fall of the iron curtain,” Russian military officials had threatened in the past that they would resume work on the project should relations with the US over anti-missile defense treaties stall.
“Whatever it is, [Object 2014-28E] looks experimental,” Patricia Lewis, research director at think-tank Chatham House and an expert in space security, told The Financial Times. “It could have a number of functions, some civilian and some military. One possibility is for some kind of grabber bar. Another would be kinetic pellets which shoot out at another satellite. Or possibly there could be a satellite-to-satellite cyber attack or jamming.”
Business Insider reporter Pierre Bienaimé said that both the US and Soviet Union had experimented with satellite-killing technology in the 1980s, but had let such projects lapse following the Cold War. In 2007, China used an anti-satellite device mounted on a ballistic missile to destroy one of its own aging weather probes, and the US destroyed an already de-commissioned spy satellite by ramming a non-explosive missile into it the following year.
“The difference here, of course, is that Russia’s experiment could involve an asset with more longevity, rather than a missile used just once,” Bienaimé explained. “If it is indeed a weapon, it could lend new urgency to the previously tentative race to weaponize not just air, land, and sea, but space as well.”
However, as Newsweek’s Polly Mosendz noted, the New Start Treaty signed by Russia and the US in 2010 limited “strategic offensive arms,” which likely means it prohibits a Russian satellite from purposefully disarming an American one. Furthermore, she said that the probe would be governed by the Outer Space Treaty, bars countries from placing weapons of mass description in orbit or installing such weapons on celestial bodies.
“Though experts and trackers are speculating that 2014-28E is involved in an act outlawed by the Outer Space Treaty, there is no evidence to concretely support their claim,” she added. “It may be a piece of space junk after all.”

Spice Things Up A Bit At Mealtime For Better Health And Memory

Chuck Bednar for redOrbit.com – Your Universe Online
While the old proverb claims that variety is the spice of life, a pair of recently-published studies offers a different take on things by indicating that spices can actually enhance your life in a variety of ways – specifically, by boosting the memory of those at risk of cognitive impairment and by reducing heart disease risk.
In one study, which appears in the Asia Pacific Journal of Clinical Nutrition, Emeritus Professor Mark Wahlqvist from the Monash Asia Institute at Monash University and his colleagues indicated that adding one gram of the spice turmeric to breakfast could enhance the cognitive function of those who are in the early stages of diabetes, a disease which has been linked to dementia.
Wahlqvist explained that the world’s aging population means that the factors which predispose people to diabetes are on the rise, and that early intervention could help prevent or reduce the impact of the disease. In their study, the authors tested the working memory of people who were at least 60 years of age and had untreated pre-diabetes.
“Working memory is widely thought to be one of the most important mental faculties, critical for cognitive abilities such as planning, problem solving and reasoning,” the professor explained in a statement. “Assessment of working memory is simple and convenient, but it is also very useful in the appraisal of cognition and in predicting future impairment and dementia.”
In their placebo-controlled study, the research team gave subjects one gram of turmeric with a breakfast of white bread, testing their memory both before and after the meal. Turmeric, a yellow spice commonly used in Asian cooking, contains a substance known as curcumin that previous studies have found reduces the risk of dementia.
“We found that this modest addition to breakfast improved working memory over six hours in older people with pre-diabetes,” Professor Wahlqvist said. “Our findings with turmeric are consistent with these observations, insofar as they appear to influence cognitive function where there is disordered energy metabolism and insulin resistance.”
In a separate study, a team of nutritionists from Penn State University found that spices and herbs that are rich in antioxidants could help improve triglyceride concentrations and other blood lipids. Triglyceride levels rise after eating a high-fat meal, they explained, which could increase a person’s risk of heart disease.
By adding garlic powder, rosemary, oregano, cinnamon, cloves, paprika, turmeric, ginger and black pepper into a meal, however, the study authors found that a person’s triglyceride levels could be reduced by up 30 percent versus an identical meal prepared without the special spice blend.
“The metabolic effects of spices and herbs and their efficacy and safety relative to traditional drug therapy represent an exciting area for future research given the public health significance of cardiovascular disease,” biobehavioral health and nutritional sciences professor Sheila G. West and nutritional sciences research associate Ann C. Skulas-Ray wrote in the latest edition of the journal Nutrition Today.
West and Skulas-Ray analyzed three different types of substances – spice blends, cinnamon and garlic. They reviewed several cinnamon studies which looked at the impact of the spice on both diabetics and non-diabetics, and found that it could help diabetics by significantly reducing cholesterol and other blood lipids in the study participants. However, it appeared to have no effect on those without diabetes.
The garlic studies proved inconclusive, and the researchers believe the reason was that the trials used a wide range of garlic doses, ranging from nine milligrams of garlic oil to 10 grams of raw garlic. However, West and Skulas-Ray said that, across the research studies, there was an eight percent decrease in total cholesterol reported with garlic consumption, accounting for a 38 percent decrease in risk of heart problems in 50-year-old adults.
As for the spice-blend study, West, Skulas-Ray and their colleagues prepared meals on two separate days for six men, ages 30 to 65, who were overweight but were otherwise in good health. The meals were identical (chicken, bread and a dessert biscuit), except that two tablespoons of a high-antioxidant culinary spice blend was added to the test meal.
“The researchers followed the participants for three hours after each meal, drawing blood every 30 minutes,” the university said in a statement. “Antioxidant activity in the blood increased by 13 percent after the men ate the test meal when compared to the control meal, which may help prevent cardiovascular disease and other chronic diseases.”

High Trans Fat Diets Linked To Diminished Memory In Men

Chuck Bednar for redOrbit.com – Your Universe Online

Researchers from the University of California, San Diego (UCSD) School of Medicine have found that eating a diet high in trans fats could potentially damage the memory of men under the age of 45.

Lead author Dr. Beatrice A. Golomb and her colleagues, who reported their findings at the American Heart Association’s Scientific Sessions 2014 conference in Chicago on Tuesday, studied approximately 1,000 healthy men and found that those who consumed the most trans fat performed the worst on word-based memory tests.

“People were presented with a series of cards with words on them, and they had to decide if they were repeats, or newly-presented words,” Dr. Golomb, a professor of medicine at UCSD, told WebMD Health News reporter Matt Sloane. “Each additional gram of trans fat consumed per day was associated with .76 fewer words recalled.”

At first glance, that might not seem like a high figure, but the researchers said that highest consumers of trans fat were getting roughly 15 grams per day, which would be associated with 11 or 12 fewer words recalled, or a 10 percent drop in memory. The strength of the association remained, even after factors such as age, education, ethnicity and depression were taken into consideration, they added.

“Trans fats were most strongly linked to worse memory, in young and middle-aged men, during their working and career-building years,” Dr. Golomb said in an American Heart Association blog post. “From a health standpoint, trans fat consumption has been linked to higher body weight, more aggression and heart disease. As I tell patients, while trans fats increase the shelf life of foods, they reduce the shelf life of people.”

She and her associates recruited adults that had not been diagnosed with heart disease – including men who were at least 20 years of age and postmenopausal women – and had them complete a questionnaire about their eating habits. Using that information, they estimated trans fat consumption, then used the word test to assess memory.

The study authors believe that the possible link they discovered between trans fat consumption and loss of recall is due to the impact of trans fat on a person’s cells, which can reduce blood flow to some of the most essential regions of the brain. This effect has also been linked to an increased risk of heart disease, stroke, and some cancers.

“Trans fats increase the shelf life of the food but reduce the shelf life of the person,” Dr. Golomb told USA Today. “They’re a metabolic poison and that’s not a good thing to be putting into your body. They don’t provide anything the body needs.”

“Foods have different effects on oxidative stress and cell energy,” she added. “In a previous study, we found chocolate, which is rich in antioxidants and positively impacts cell energy, is linked to better word memory in young to middle-aged adults. In this study, we looked at whether trans fats, which are prooxidant and linked adversely to cell energy, might show the opposite effect. And they did.”

The research was supported by the National Heart, Lung, and Blood Institute (NHLBI).

Tired, Overworked And Irritable? You May Need To Watch Out For Your Heart Health

Brett Smith for redOrbit.com – Your Universe Online

Chronic fatigue, irritability and dejection are hard enough to deal with on their own, but even harder as a collective group known as vital exhaustion.

Unfortunately, vital exhaustion can lead to increased risk of a heart attack or stroke, according to a new study presented at the American Heart Association’s annual meeting this week in Chicago.

“Our study shows vital exhaustion is an important risk factor for the development of cardiovascular disease in otherwise healthy people,” said study author Dr. Randy Cohen, medical director of the University Medical Practice Associates at Mount Sinai St. Luke’s. “Loss of vitality thus adds to a growing number of psychosocial risk factors that have now been linked to the development of cardiovascular disease, including anxiety, depression, and social isolation.”

To reach their conclusion, the study team looked at the connection between vital exhaustion and the development of heart disease in 11 preliminary research studies, which included greater than 60,000 people without cardiovascular disease.

The study team saw that there was a 36-percent risk increase of first-time cardiovascular disease for patients with vital exhaustion.

“The identification of vital exhaustion as a coronary artery disease (CAD) risk factor appears timely,” said co-author Dr. Alan Rozanski, chief of cardiology at Mount Sinai St. Luke’s and Mount Sinai Roosevelt. “As society becomes increasingly fast paced, there is an increasing tendency for people to overwork while cutting back on sleep, exercise, and the rest and relaxation we all need to renew ourselves and prevent the factors that cause vital exhaustion.”

Researchers are also increasingly becoming worried about chronic fatigue and a study published several weeks ago revealed that intense exhaustion is connected to structural abnormalities in the brain.

“This is a very common and debilitating disease,” said study author Dr. Michael M. Zeineh, an assistant professor of radiology at Stanford University. “It’s very frustrating for patients, because they feel tired and are experiencing difficulty thinking, and the science has yet to determine what has gone wrong.”

Using magnetic resonance imaging (MRI) technology, the study team saw that total white-matter content in chronic fatigue patients’ brains was lower as opposed to that of control subjects’ brains. “White matter” refers to the long, cable-like nerve areas transporting signals among generally dispersed quantities of “gray matter,” which specializes in handling data.

The scientists regularly saw an abnormality in a section of the right hemisphere of fatigue patients’ brains known as the right arcuate fasciculus. The study team noted a correlation between the amount of abnormality in a patient’s right arcuate fasciculus and the degree of their chronic fatigue.

The researchers said their results support the use of right arcuate fasciculus size as a biomarker for chronic fatigue syndrome (CFS).

“We used automated techniques to look at these tracts and were able to achieve 80 percent accuracy for CFS detection,” Zeineh said.

“This is the first study to look at white matter tracts in CFS and correlate them with cortical findings,” he added. “It’s not something you could see with conventional imaging.”

Uber Exec Blasted For Remarks Made Regarding Journalists

Chuck Bednar for redOrbit.com – Your Universe Online
A senior executive at ride-sharing service Uber has taken a wrong turn down a somewhat precarious road after suggesting that the company should consider hiring “opposition researchers” to investigate media personnel who were critical of the company, various media outlets reported on Monday,
According to Chris Taylor of Mashable, the comments were made by Senior Vice President Emil Michael at what was described as “a private off-the-record dinner” held Friday in New York. Michael reportedly said that Uber could spend up to $1 million to investigate the personal lives and families of journalists, and that “nobody would know” the firm was behind it.
“During the dinner, Michael specifically attacked PandoDaily editor Sarah Lacy for writing an editorial accusing Uber of ‘sexism and misogyny’ for running a promotion featuring ‘hot chick’ drivers,” added Ars Technica reporter Casey Johnston. Michael went on to state that Lacy should be held “personally responsible” if a woman deleted Uber and was then sexually assaulted, and that there was “a particular and very specific claim” about her life that could be exposed.
Michael’s comments were overheard by an unnamed editor at BuzzFeed, reporter Ben Smith wrote on Monday. That editor was invited to the dinner by journalist Michael Wolff, who later said that he had failed to properly convey that the gathering was intended to be off-the-record. Smith said that nobody, including Uber CEO Travis Kalanick or the company’s communication director, gave any indication that the event was not to be reported on.
“Over dinner, he outlined the notion of spending ‘a million dollars’ to hire four top opposition researchers and four journalists. That team could, he said, help Uber fight back against the press – they’d look into ‘your personal lives, your families,’ and give the media a taste of its own medicine,” Smith said, adding that the VP gave no indication that Uber had hired opposition researchers, or had any plans to, just that they would be justified in doing so.
In a statement issued through an Uber spokeswoman and reprinted by BuzzFeed, Michael said, “The remarks attributed to me at a private dinner – borne out of frustration during an informal debate over what I feel is sensationalistic media coverage of the company I am proud to work for – do not reflect my actual views and have no relation to the company’s views or approach. They were wrong no matter the circumstance and I regret them.”
Kalanick also condemned the remarks, calling them “terrible” and noting that they do not represent the company, according to USA Today. He added that Michael’s remarks “showed a lack of leadership, a lack of humanity, and a departure from our values and ideals,” but did not mention whether or not he still worked at Uber or had been in any way disciplined.
“It’s not the first time the company has been under fire for overly aggressive tactics,” Taylor said. “This summer the company reportedly assembled a ‘street team’ tasked with signing up for accounts with its rival service, Lyft, then ordering rides and canceling them. Lyft said it had lost 5,000 rides over a 10-month period to such tactics; another startup called Gett said it had fallen victim to the same tactics from Uber, for which Uber later apologized.”
On Wednesday morning, the non-profit Consumer Federation of California called on Uber to fire Michael.
“Uber’s arrogance knows no bounds. Uber’s contempt for privacy and a free press begins in its executive suite. The company endangers passengers by evading well-established transportation industry insurance, safety and fare regulations. It runs ads that are an invitation to sexual abuse of female drivers, and it contemplates dirty trick campaigns against those who dare to point out the company’s many flaws,” stated Richard Holober, Executive Director of the Consumer Federation of California. “Uber should fire Emil Michael. It’s time for Uber to learn the rules of fair play that Americans expect.”

Exploring Link Between Memory Deficit And Misfiring Circadian Clock

Provided by Bjorn Carey, Stanford University
By disrupting Siberian hamsters’ circadian rhythms, Stanford scientists have identified a part of the brain that, when misfiring, inhibits memory. The work could lead to therapies for neurodegenerative diseases in humans.
Anyone who has struggled with a foggy brain while adjusting to daylight saving time knows first-hand how an out-of-sync circadian clock can impair brain function.
Now, by manipulating the circadian clocks of Siberian hamsters, Stanford scientists may have identified a brain structure that disrupts memory when circadian rhythms fall apart, as they often do in patients with neurodegenerative diseases such as Alzheimer’s.
“What we’ve been able to show is that the part of the brain that we absolutely know contains the circadian clock, the suprachiasmatic nucleus (SCN), also has an important role in learning and memory,” said Norman Ruby, a senior research scientist of biology at Stanford and senior author on the study. “When that clock doesn’t work well, memory deficits show up.”
Importantly, the researchers found that a broken clock impairs memory, but when they surgically removed the SCN from the hamsters, their memory abilities returned in full force, creating the possibility for new therapies.
Ruby and his colleagues designed an elegant experiment to zero in on the SCN’s role in memory. First, they trained Siberian hamsters in a standard learning and memory task, which involved familiarizing them with two objects and then, some time later, changing up one of the objects and seeing if the rodents noticed. On the whole, the animals excelled at the test.
Once the animals had mastered the task, the researchers exposed them to light at odd intervals, which threw off their circadian rhythms. The arrhythmic hamsters were then given the same memory task, and failed miserably.
Next, the researchers surgically removed each hamsters’ SCN, essentially eliminating it from the memory circuit, and gave the memory test a third time. Even though the animals’ circadian rhythms were still out of sync, the animals performed the test as well as they had at the beginning of the experiment.
The reason this works isn’t entirely understood, Ruby said, but this experiment shows that when an arrhythmic SCN is misfiring, it chronically inhibits learning and memory.
Elderly people with neurodegenerative memory deficiencies also often complain of poor sleep, which can be associated with weakened circadian timing. These symptoms were believed to be coincidental, Ruby said, but recently scientists have begun to connect the two, and have tried to treat memory disorders by fixing the circadian clock.
These approaches have proven complex and are not always easy to implement, Ruby said. The new work suggests that rather than repairing the systems responsible for a misfiring SCN, it might be more productive to simply remove it from the equation.
“The more I investigate it, the idea of shutting off the SCN as a way of restoring memory ability in humans seems more provocative and possibly doable,” Ruby said. “If you are treating a a neurodegenerative brain, rather than fixing the circadian clock, it might be easier to just pharmacologically shut down the SCN.
“I’m pretty excited about exploring this as a new target for treating some types of adult memory disorders.”
The research, published in the current issue of Science, was co-authored by Fabian Fernandez, who conducted the work while earning his PhD in neuroscience at Stanford, and biology professor H. Craig Heller. Four of Ruby’s former undergraduate students – Derek Lu, Phong Ha, Patricia Costacurta and Renee Chavez – contributed to the work and are also named as co-authors.

The Dirty Side Of Personal Hygiene Products

Provided by Heather Buschman, PhD, University of California – San Diego

Triclosan is an antimicrobial commonly found in soaps, shampoos, toothpastes and many other household items. Despite its widespread use, researchers at University of California, San Diego School of Medicine report potentially serious consequences of long-term exposure to the chemical. The study, published Nov. 17 by Proceedings of the National Academy of Sciences, shows that triclosan causes liver fibrosis and cancer in laboratory mice through molecular mechanisms that are also relevant in humans.

“Triclosan’s increasing detection in environmental samples and its increasingly broad use in consumer products may overcome its moderate benefit and present a very real risk of liver toxicity for people, as it does in mice, particularly when combined with other compounds with similar action,” said Robert H. Tukey, PhD, professor in the departments of Chemistry and Biochemistry and Pharmacology. Tukey led the study, together with Bruce D. Hammock, PhD, professor at University of California, Davis. Both Tukey and Hammock are directors of National Institute of Environmental Health Sciences (NIEHS) Superfund Programs at their respective campuses.

Tukey, Hammock and their teams, including Mei-Fei Yueh, PhD, found that triclosan disrupted liver integrity and compromised liver function in mouse models. Mice exposed to triclosan for six months (roughly equivalent to 18 human years) were more susceptible to chemical-induced liver tumors. Their tumors were also larger and more frequent than in mice not exposed to triclosan.

The study suggests triclosan may do its damage by interfering with the constitutive androstane receptor, a protein responsible for detoxifying (clearing away) foreign chemicals in the body. To compensate for this stress, liver cells proliferate and turn fibrotic over time. Repeated triclosan exposure and continued liver fibrosis eventually promote tumor formation.

Triclosan is perhaps the most ubiquitous consumer antibacterial. Studies have found traces in 97 percent of breast milk samples from lactating women and in the urine of nearly 75 percent of people tested. Triclosan is also common in the environment: It is one of the seven most frequently detected compounds in streams across the United States.

“We could reduce most human and environmental exposures by eliminating uses of triclosan that are high volume, but of low benefit, such as inclusion in liquid hand soaps,” Hammock said. “Yet we could also for now retain uses shown to have health value — as in toothpaste, where the amount used is small.”

Triclosan is already under scrutiny by the FDA, thanks to its widespread use and recent reports that it can disrupt hormones and impair muscle contraction.

Young Teen Smokers May Run Heightened Risk Of Chronic Severe Period Pain

Provided by Emma Dickinson, BMJ-British Medical Journal

Starting smoking by age of 13 may have greatest impact

Most women will experience period pain (dysmenorrhoea) during their reproductive life, with the pain severe in up to 29%.

Smoking has been mooted as a potential risk factor, but the research to date has been inconclusive.

The study authors studied a large population sample of 9000 women, all of whom were taking part in the Australian Longitudinal Study on Women’s Health, from 1996 onwards.

Every 3-4 years between 2000 and 2012, the women were asked about the frequency of severe period pain they had experienced, and whether they currently or had ever smoked. Current and ex-smokers were asked at what age they started.

Information was also collected on other key influential factors, such as educational attainment, marital status, employment, residential area, weight, lifestyle and reproductive history.

In 2000, when the women were aged between 22 and 27, over half (59%) were non-smokers and around one in four (26%) were current smokers.

Around 7% of the women had started smoking by the age of 13, with a further 14% starting their habit at the age of 14-15. And 8% said they had started smoking before they began having monthly periods.

In 2000, one in four women said they regularly experienced period pain every month. The prevalence of period pain was slightly higher in current smokers (29%) than in non-smokers (23%).

The women were divided into four groups according to the type and duration of period pain they had.

The ‘normative’ group comprised 42% of the total sample, defined by no or few symptoms throughout the monitoring period; 11% of the women were categorized as ‘late onset,’ defined by an increasing prevalence of period pain from 15% to nearly 70%.

The ‘recovering’ group comprised 33% of the women, defined by a decreasing prevalence of period pain from 40% at the age of 22-27, to 10% by the age of 34-39.

Some 14% of the women were categorized as the ‘chronic’ group, defined as a high prevalence of period pain of between 70% and 80% throughout the monitoring period.

Compared with women who had never smoked, current smokers who had started smoking by the age of 13 were more likely to be in the chronic group, as were women who were unemployed, had started their periods early, who were obese, and who spoke a European language at home.

After taking account of influential factors, current smokers who had started smoking by the age of 13, were 60% more likely to fall into the chronic group than non-smokers.

This is an observational study so no definitive conclusions can be drawn about cause and effect, but there are possible explanations for the association, say the authors.

Cigarette smoking is known to constrict arterial blood flow, which could potentially cause pain. Alternatively, it might have a direct effect on the hormones involved in menstruation, which may be particularly important before the onset of puberty and regular monthly periods, say the authors.

Vape Named Oxford Dictionary’s Word Of The Year For 2014

Chuck Bednar for redOrbit.com – Your Universe Online
Thanks to the growing popularity of e-cigarettes, ‘vape’ beat out the likes of ‘bae’ and ‘contactless’ to take top honors as the Oxford Dictionaries Word of the Year for 2014, officials at the popular language compendium announced on Monday
The term vape “originated as an abbreviation of vapor or vaporize,” they explained. “The OxfordDictionaries.com definition was added in August 2014: the verb means ‘to inhale and exhale the vapor produced by an electronic cigarette or similar device’, while both the device and the action can also be known as a vape.”
According to BBC News, readers are now 30 times more likely to encounter the word vape than they were two years ago. However, the earliest known use of the term dates back to a 1983 article entitled “Why Do People Smoke?” in which the author described “an inhaler or non-combustible cigarette” capable of “delivering a metered dose of nicotine vapor,” a “new habit… known as vaping.”
While e-cigarettes themselves were invented over 10 years ago, Gail Sullivan of The Washington Post explained that the increased popularity of the devices as of late has had a noticeable impact on the English language, spurring the retronym “tobacco cigarette” to distinguish electronic from traditional ones, as well as “throat hit” to describe the sensation experienced by the user and several other new terms associated with the habit.
“Traditional cigarettes are also referred to as ‘analog’ or ‘hot cigarettes,’” Sullivan said, noting that the e-cig community also uses such terminology as “e-juice” for the liquid that turns to vapor, “carto” which is short for the cartomizer or the disposable cartridge that holds e-juice, and “vaporium” for a place that markets e-cigarettes.
Some of the other words edged out by vape, include: bae, a noun used as “a term of endearment for one’s romantic partner” (and a work that was also a candidate for Time magazine’s recent “Which Word Should Be Banned in 2015?” poll, according to Sullivan); budtender, a term used to refer to a person to serves customers at a cannabis dispensary; contactless, an adjective used to describe technologies that allow smart cards or mobile devices to send wireless payments to an electronic reader.
Rounding out the shortlist are indyref, an abbreviation of “independence referendum” used to describe the September vote for independence in Scotland; normcore, a noun used to describe the trend of wearing ordinary, unfashionable clothing in order to make an intentional fashion statement; and slacktivism, a blend of slacker and activism used to refer to informal actions performed online in support of political or social causes, but which require little actual time or effort (for example, signing an online petition or joining a campaign group on a social media website).
Vape joins the likes of ‘selfie,’ which was named the 2013 Word of the Year last November and was defined by the dictionary as “a photograph that one has taken of oneself, typically with a smartphone or webcam and uploaded to a social media website.” Selfie ultimately became so popular that it “became the name of an ABC sitcom (albeit now a canceled one),” said Mashable’s Chris Taylor.

Elon Musk Predicts Catastrophic AI Event Will Occur Within 10 Years

Chuck Bednar for redOrbit.com – Your Universe Online
Tesla CEO and SpaceX co-founder Elon Musk is once again sounding the alarm about artificial intelligence (AI), stating that “the risk of something seriously dangerous happening” could be as little as five years away.
According to re/code’s John Paczkowski, Musk responded to a post about AI at the website Edge.org with a comment that has since been deleted. In it, Musk essentially said that research into artificial intelligence was moving forward so quickly that he predicted a negative event would occur within the next decade.
He also went on to defend himself from potential criticism by stating that his views were “not a case of crying wolf about something I don’t understand,” added James Cook of Business Insider. Musk added by saying that he is “not alone in thinking we should be worried. The leading AI companies… recognize the danger, but believe that they can shape and control the digital superintelligences and prevent bad ones from escaping into the Internet. That remains to be seen.”
Musk’s representatives confirmed the authenticity of the comments to Paczkowski. A spokesperson said that Musk sent his views to Edge.org founder John Brockman via email and did not intend for them to be published. The individual added that Musk planned to write a longer blog post addressing the issue at a later date.
The South African-born inventor and entrepreneur has shared his views on the dangers of AI technology on multiple occasions. In October, while addressing those in attendance at the MIT Aeronautics and Astronautics Department’s 2014 Centennial Symposium, he compared AI to summoning demons and referred to it as the “biggest existential threat” currently faced by mankind.
Likewise, as Justin Moyer of The Washington Post pointed out, Musk said that AI was “potentially more dangerous than nukes” in August, and in June, he cautioned that the scientists in the movie The Terminator did not expect to be developing a killing machine – that they simply made the technology and were surprised by the outcome.
“It gets weirder: Musk has invested in at least two artificial intelligence companies – one of which, DeepMind, he appeared to slight in his recent deleted blog post,” Moyer said, adding that while DeepMind “was acquired by Google in January,” it appears as though Musk was “just supporting AI companies to keep an eye on them.”
“Unless you have direct exposure to groups like DeepMind, you have no idea how fast-it is growing at a pace close to exponential,” Musk wrote, according to The Washington Post. “It’s not from the standpoint of actually trying to make any investment return. It’s purely I would just like to keep an eye on what’s going on with artificial intelligence.”
Musk also recently invested in Vicarious, a firm working to design a computer capable of thinking like a person, Paczkowski noted. His involvement in such projects and his views on artificial intelligence led Moyer to ponder exactly what these firms are working on that has him so concerned – or, as Paczkowski put it, “Makes you wonder just what the hell is going on over there that has so unsettled him, doesn’t it?”

Most Parents Believe All Children In Daycare Should Be Vaccinated

Chuck Bednar for redOrbit.com – Your Universe Online
Nearly three-fourths of all parents in the US said that they would consider removing their children from a daycare center if they knew that other youngsters there had not been vaccinated, according to the University of Michigan C.S. Mott Children’s Hospital National Poll on Children’s Health.
While all states require children who attend daycare to receive vaccines, those requirements may not necessarily include every vaccine from birth through age five, the researchers said. As a result, some kids still do not receive all recommended immunizations, leaving parents and daycare providers left to decide how to deal when a situation arises involving a child who is not fully up-to-date on all of their booster shots.
In June 2014, experts from the C.S. Mott Children’s Hospital polled a national sample of parents of children aged birth through 5-years-old, and found that 81 percent of parents agree or strongly agree that all children in daycare centers should be vaccinated, and that the majority of them (74 percent) agree or strongly agree that daycare providers should ensure that all participating children’s immunization status is up to date every year.
[ Watch the Video: Many Parents Would Remove Kids From Daycare If Others Are Unvaccinated ]
“Results of this poll indicate that most parents want strong policies around making sure children in daycare are up-to-date on vaccines,” Sarah J. Clark, associate director of the National Poll on Children’s Health and associate research scientist in the University of Michigan Department of Pediatrics, said in a statement Monday.
“Checking vaccination records every year is beyond the scope of many state requirements, and may represent a significant change in practice at many daycares,” she added. “Our poll finding that parents want to know the number of children lacking vaccines makes sense. That information might help parents understand the risk that their child could contract a vaccine-preventable disease – or transmit the disease to a vulnerable family member.”
Parents who participated in the survey were presented with a scenario in which one-fourth of the children in their kids’ daycare center were not up-to-date on vaccines – a situation which Clark said mirrors national statistics indicating that roughly 25 percent of preschool children in American have not been fully vaccinated.
When asked how they felt daycare facilities should deal with a situation involving a child who did not have up-to-date vaccines, 41 percent of parents said they were in favor of excluding the youngster until all of his/her vaccines were received, while 28 percent said there should be a grace period and 21 percent insisted that the parent provide a waiver from the child’s doctor. Only 10 percent were in favor of allowing the child to continue attending as-is.
In addition, Clark revealed that 39 percent of parents said they would definitely consider pulling their children out of that daycare center in this particular situation, and another 35 percent said that they probably would consider doing so. She said this indicates how seriously parents take the risk of disease spreading through unvaccinated children, and that it was perfectly legitimate to ask daycare providers questions about this issue.
“Our poll finding that parents want to know the number of children lacking vaccines makes sense. That information might help parents understand the risk that their child could contract a vaccine-preventable disease – or transmit the disease to a vulnerable family member, such as a person with cancer,” Clark said. “Parents should feel empowered to ask about daycare vaccination policies, such as how the daycare handles the situation of children who are not up-to-date, and whether they check children’s vaccination status every year.”

Virus Responsible For Sea Star Wasting Disease Discovered

Chuck Bednar for redOrbit.com – Your Universe Online
Over the past 18 months, experts have been puzzled by the unusual and gruesome deaths of millions of starfish along the Pacific Coast of North America, but now the authors of a new Proceedings of the National Academy of Sciences study have discovered the pathogen responsible for the phenomenon.
Ian Hewson, a professor of microbiology in the Cornell University College of Agriculture and Life Sciences, and his colleagues have identified the mysterious disease that causes the limbs of the sea stars to pull away from their bodies and their organs to exude through their skins as Star Associated Densovirus (SSaDV).
[ Watch the Video: Researchers Examine Sea Star Associated Densovirus ]
SSaDV is a type of parvovirus commonly found in invertebrates, and according to Jane J. Lee of National Geographic, it is a type of parvovirus similar to the pathogen that cause gastrointestinal problems in unvaccinated dogs. The bad news is that, even though the researchers now know the cause, there’s little they can do to stop the virus.
“We can’t quarantine, we can’t effectively cull, and we can’t vaccinate,” co-author Drew Harvell, a marine ecologist at Cornell, told Lee during an interview earlier this year. However, in a statement released Monday, Harvell said that the research does lay the groundwork for learning more about how the densovirus kills sea stars and what exactly causes outbreaks of the disease known as Sea Star Wasting Disease (SSWD).
“It’s the experiment of the century for marine ecologists,” Harvell said, explaining that the ocean floor-dwelling sea stars are voracious predators and play a vital role in maintaining the biodiversity of their ecosystem. “It is happening at such a large scale to the most important predators of the tidal and sub-tidal zones. Their disappearance is an experiment in ecological upheaval the likes of which we’ve never seen.”
According to the Natural History Museum of Los Angeles County, which provided specimens for the researchers to analyze, the study indicates the virus has survived at a low level for more than seven decades. It was detected in preserved sea stars that were collected as early as 1942 and as recently as 1991, and the study suggests that SSaDV may have recently risen to epidemic levels due to starfish overpopulation, environmental changes, or mutation of the virus.
While Lee said that the long-term impact of the virus remains to be seen, currently infected sea stars such as the sunflower star and the purple or ochre star wind up meeting a gruesome end. SSaDV weakens the creature, leaving it vulnerable to bacterial infection that ultimately kills the starfish, Hewson explained. Within eight to 17 days after becoming infected, their bodies become covered in white lesions and they become lethargic. Sometimes, their arms rip themselves off and walk away, Lee said, and ultimately it winds up deflating into a pile of white slime.
“The recent outbreak of sea star wasting disease on the U.S. West Coast has been a concern for coastal residents and marine ecologists,” said David Garrison, program director at the National Science Foundation (NSF) Division of Ocean Sciences. “This study… has made a significant contribution to understanding the disease.”

X-ray Laser Imaging Method Successfully Tested On Nanoscale Biological Samples

Provided by Linda Koffmar, Uppsala University

An international team of scientists led by Uppsala University has developed a high-throughput method of imaging biological particles using an X-ray laser. The images show projections of the carboxysome particle, a delicate and tiny cell compartment in photosynthetic bacteria.

The experiment, described in a paper published today in the scientific journal Nature Photonics, represents a major milestone for studies of individual biological structures using X-ray lasers. The technique paves the way for 3D imaging of parts of the cell, and even small viruses, to develop a deeper understanding of life’s smallest units.

To test the method, scientists from Uppsala University, the European XFEL, DESY and a number of other institutions used the carboxysome. The carboxysome is a cell organelle for CO2 assimilation in cyanobacteria that has been extensively studied in Uppsala by Dirk Hasse and Inger Andersson. Carboxysomes contain protein machinery that incorporates carbon from carbon dioxide into biomolecules. About a third of global carbon fixation happens in carboxysomes.

The carboxysome is a tiny structure — only about 115 nanometers across, too small to clearly see with an optical microscope. A nanometer is a millionth of a millimeter.

Using a specially designed injector that produces a particle stream thinner than a human hair, the scientists sprayed an aerosol of carboxysomes across the beam of the LCLS X-ray laser at the SLAC National Accelerator Laboratory in the US. The scientists calculated the structure of the organelles by analyzing the way the carboxysomes scatter the extremely short and ultra bright X-ray flashes of the LCLS. Up until now, this method required crystals of the sample material to get sufficient signal. Thanks to the extreme brightness of the X-ray laser and clever analysis of the diffraction patterns, the researchers could reconstruct individual samples without having to crystallize them. Carboxysomes like many other biological samples vary in shape and size and therefore cannot be crystallized.

Within 12 minutes, the researchers collected 70,000 scattering patterns from individual particles. The analysis returned an icosahedral shape (a structure with 20 triangle-shaped sides) for carboxysomes, in line with expectations. The results also showed considerable variation in size.

“Our method allows single-particle imaging of objects which can be different in size and shape,” says Max Hantke, a doctoral student in molecular biophysics at Uppsala University in Sweden who led the research.

While electron microscopy usually requires samples to be frozen, X-ray lasers like the LCLS or the European XFEL, which is currently being built in Germany, can analyze biological samples without freezing. This method also offers the possibility to image whole living cells at unprecedented resolution.

“With the carboxysomes we have reconstructed the smallest single biological particles ever imaged with an X-ray laser, and we were also able to improve resolution. The reconstruction shows details as small as about 18 nanometres. For the first time we access a very interesting size regime with an X-ray laser. Large pathogenic viruses like HIV, influenza-, and herpes virus are in the same size domain as the carboxysome,” says Max Hantke.

“These advances lay the foundations for accurate, high-throughput structure determination by flash-diffractive imaging and offer a means to study structure and structural heterogeneity in biology and elsewhere,” says Professor Janos Hajdu, who is also one of the lead authors on the paper and one of Hantke’s mentors as well as an advisor to European XFEL.

“Additionally, the size distribution of the carboxysomes before the experiment and what was seen in the resulting data matched almost perfectly,” says Max Hantke, suggesting the organelles that were imaged were structurally intact.

While the intense X-ray pulse destroys the sample, an accurate diffraction pattern can be acquired before it disintegrates. This method, called “diffraction-before-destruction,” was proposed in 2000 by the Uppsala group and was demonstrated with non-biological samples at DESY’s FLASH facility in 2006.

Such single-particle imaging will be possible at the European XFEL when the facility opens to users in 2017. Two dedicated instruments will be available for such studies, the SPB instrument (Single Particles and Biomolecules) and the SFX instrument (Serial Femtosecond Crystallography), which will incorporate a similar sample injector to the one used in this experiment. With its 27,000 X-ray flashes per second and even higher intensity, the European XFEL will open up more opportunities and possibilities for researchers.

“In biology, there is heterogeneity at all levels, and we wanted a method for seeing it below the cellular level,” says Janos Hajdu.

“We hope this research could lead to three-dimensional models showing the diversity of nanoscale cell parts,” Max Hantke adds.

“These results show the way to high-throughput imaging of biological samples at high resolution. High data rates and very short exposures allow studies on the dynamics of particles and permit the analysis of structural variations, which are crucially important for life,” says Filipe Maia, supervisor of Max Hantke.

Ferret Genome Sequenced, Holds Clues To Respiratory Diseases

Genetic analysis unveils airway and lung responses to pandemic flu and cystic fibrosis

In what is likely to be a major step forward in the study of influenza, cystic fibrosis and other human diseases, an international research effort has sequenced the ferret genome. The sequence was then used to analyze how the flu and cystic fibrosis affect respiratory tissues at the cellular level.

The National Institute of Allergy and Infectious Diseases, of the National Institutes of Health, funded the project, which was coordinated by Michael Katze and Xinxia Peng at the University of Washington in Seattle and Federica Di Palma and Jessica Alfoldi at the Broad Institute of MIT and Harvard.

“The sequencing of the ferret genome is a big deal,” said Michael Katze, UW professor of microbiology, who led the research effort. “Every time you sequence a genome, it allows you to answer a wide range of questions you couldn’t before. Having the genome changes a field forever.”

Ferrets have long been considered the best animal model for studying a number of human diseases, particularly influenza, because the strains that infect humans also infect ferrets, These infections spread from ferret to ferret much as they do from human to human.

In the study, scientists at Di Palma and Alfoldi of the Broad Institute first sequenced and annotated the genome of a domestic sable ferret (Mustela putorius furo). They then collaborated with the Katze group on the subsequent analysis. A technique called transcriptome analysis identifies all the RNA that is being produced, or “transcribed,” from areas of the genome that are activated at any moment. This makes it possible to see how the ferret cells are responding when challenged by influenza and cystic fibrosis.

“By creating a high quality genome and transcriptome resource for the ferret, we have demonstrated how studies in non-conventional model organisms can facilitate essential bioscience research underpinning health,” said Di Palma, director of Science in Vertebrate & Health Genomics at The Genome Analysis Centre.

Pucker Up! Swapping Spit Shares More Than Just Your Feelings For Someone

Brett Smith for redOrbit.com – Your Universe Online
From dessert at a fancy restaurant to a taxi across town, two people in a loving, passionate relationship might share many things and, according to a new study, they also probably share the same community of oral bacteria.
Published in the journal Microbiome, the new study found that up to 80 million bacteria are passed from mouth-to-mouth during a 10-second kiss. The study team also found that romantic partners who kiss each other at least nine times a day have nearly identical oral bacteria communities.
“Intimate kissing involving full tongue contact and saliva exchange appears to be a courtship behavior unique to humans and is common in over 90 percent of known cultures,” noted study author Remco Kort, a cell physiologist at VU University Amsterdam. “Interestingly, the current explanations for the function of intimate kissing in humans include an important role for the microbiota present in the oral cavity, although to our knowledge, the exact effects of intimate kissing on the oral microbiota have never been studied.”
“We wanted to find out the extent to which partners share their oral microbiota, and it turns out, the more a couple kiss, the more similar they are,” Kort added.
In the study, researchers asked 21 couples to complete surveys on their kissing habits, including their average intimate kiss regularity. The team also acquired swab samples to research the make-up of participants’ oral bacteria community.
The researchers saw that when romantic partners intimately kiss fairly often, their salivary bacteria turn out to be highly comparable. Typically, it was discovered that nine intimate kisses or more per day led to partners having similar salivary communities.
The study team also conducted an experiment to measure the exchange of microorganisms caused by a kiss. In the experiment, one person from each couple drank a probiotic beverage containing distinct varieties of microorganisms; including the benign Lactobacillus and Bifidobacteria bacteria. After a lengthy kiss, the scientists assessed that the amount of probiotic bacteria in the receiver’s mouth tripled, meaning 80 million bacteria overall would have been shifted within a 10 second kiss.
The study also revealed that while tongue bacteria were more similar among partners than unrelated individuals, their likeness did not switch with more common kissing, in comparison to the results for salivary bacteria.
“French kissing is a great example of exposure to a gigantic number of bacteria in a short time,” Kort told BBC News reporter Smitha Mundasad. “But only some bacteria transferred from a kiss seemed to take hold on the tongue.”
As a side note, the study revealed that 74 percent of male respondents reported greater intimate kiss frequencies than a female partner, an average of ten kisses per day reported from the males compared to an average of five per day from their partner.
“Further research should look at the properties of the bacteria and the tongue that contribute to this sticking power,” Kort told Mundasad. “These types of investigations may help us design future bacterial therapies and help people with troublesome bacterial problems.”

Impact Of Secondhand Pot Smoke On Heart Health

Chuck Bednar for redOrbit.com – Your Universe Online
Secondhand marijuana smoke could be as damaging to your heart and blood vessels as secondhand cigarette smoke, researchers from the University of California, San Francisco (UCSF) reported at the American Heart Association’s Scientific Sessions 2014 in Chicago on Sunday.
In the preliminary study, the authors reported that blood vessel function in laboratory rats that had been exposed to secondhand marijuana smoke for 30 minutes dropped 70 percent, even when it did not contain tetrahydrocannabinol (THC), the compound in marijuana that produces intoxication. That reduced blood vessel function could increase the chances of developing atherosclerosis, which causes plaque built-up in the arteries and could result in a heart attack.
“Smoke is smoke,” senior author Matthew Springer, a cardiovascular researcher and associate professor of medicine in the UCSF cardiology division, told Dennis Thompson of HealthDay News. “Both tobacco and marijuana smoke impair blood vessel function similarly. People should avoid both, and governments who are protecting people against secondhand smoke exposure should include marijuana in those rules.”
“Marijuana for a long time was viewed as a relatively innocuous drug, but a lot of that came from a lack of information,” added Dr. Stephen Thornton, a toxicologist and medical director of the Poison Control Center at the University of Kansas Hospital. “Now, as more and more people are using it, we’re finding more and more detrimental effects. People just need to be cautious.”
Currently, medical marijuana use is legal in 23 states and Washington DC, and recreational use of the drug is permissible in Alaska, Colorado, Oregon, Washington and the District of Columbia, Thompson said. The US Surgeon General’s office reported in 2014 that secondhand tobacco smoke is responsible for approximately 34,000 premature deaths due to heart disease in nonsmokers.
Springer and his colleagues report that marijuana and tobacco are chemically similar except for THC, and the fact that the rodents experienced a reduction in blood vessel function in THC-free marijuana suggests that the compound itself is not responsible for the effect. Previous studies have found the same is true with nicotine in cigarettes.
In their research, the UCSF scientists used a modified cigarette smoking machine to expose rats to the marijuana smoke, then used a high-resolution ultrasound machine to measure the function of their main leg artery. Blood vessel dilation was recorded both before exposure to the smoke, 10 minutes afterwards, and again 40 minutes post-exposure. Separate tests were conducted with THC-free marijuana and plain air.
No difference in blood vessel function was detected when the rats were exposed to plain air, the authors said. While previous tobacco studies found that blood vessel function returned to normal 30 minutes after exposure, it had not normalized when measured 40 minutes after exposure in the marijuana study, they added.
Springer told Thompson that he came up with the idea for the study, which has not yet been peer-reviewed and was funded by the National Institute on Drug Abuse and the Elfenworks Foundation, while attending a Paul McCartney concert at which cannabis consumption was rampant.
“We were already studying the effect of secondhand tobacco smoke on vascular function, and in the middle of the concert, a bunch of people started lighting up. My first instinct was to say they can’t do that here. But then I realized it was marijuana,” he told the HealthDay reporter. “I think if people started lighting cigarettes in the middle of a stadium, people would tell them to stop. But because they were smoking marijuana, it was OK.”
“Tobacco smoke and marijuana smoke both contain thousands of chemicals, many of which are toxic,” Springer added, noting that government officials should review laws governing indoor and/or outdoor smoking to go back and see if they specifically prohibit tobacco use, or if they would also apply to marijuana smoke.

New Bird Flu Cases Confirmed In The UK And The Netherlands

Chuck Bednar for redOrbit.com – Your Universe Online
Cases of bird flu were confirmed at a UK duck breeding farm and a chicken farm in the Netherlands over the weekend, though public health officials are assuring people that the disease poses little risk to humans.
According to Maarten van Tartwijk of The Wall Street Journal, the Dutch government reported that a strain of bird flu at a farm in Hekendorp (a town located 23 miles south of Amsterdam) had been identified as the highly contagious H5N8 strain.
Government officials have prohibited the transport of poultry and eggs for the next 72 hours, and have also issued a temporary ban on hunting and poultry exhibitions, van Tartwijk added. All 150,000 chickens at the farm are being culled, representatives of the Dutch government told The Wall Street Journal.
On Monday, officials at East Yorkshire said that a case of bird flu had been confirmed at the duck breeding farm. While the exact strain had not been confirmed, the Department for Environment, Food and Rural Affairs (DEFRA) said that it is not the potentially deadly H5N1 form, according to BBC News.
The case is the first to be reported in the UK since 2008, when chickens at a Banbury, Oxfordshire farm tested positive for the virus, the British news organization added. DEFRA officials said that the risk to public health was extremely low, that 6,000 birds would be culled, and that a six-mile (10 kilometer) exclusion zone would be in effect.
UK chief veterinary officer Nigel Gibbens told the BBC that the two cases may be related, and could also be linked to a case of bird flu reported in Germany earlier this month. He went on to say that additional cases could not be ruled out, and that farmers and veterinarians needed to be alert for diseases and symptoms they cannot explain.
Gibbens also told the UK Press Association that the risk of the disease being spread was “probably quite low” because of the “quick action” taken “to remove the birds as a possible source of further infection,” as well as the exclusion zone, which restricts other farms in the area “to look for possible further spread or possible other infected farms.”
The Press Association noted that most forms of avian flu are harmless to humans, but two types – H5N1 and H7N9 – could be potentially harmful to people. World Health Organization statistics said that there have been 377 H5N1-related deaths in 15 countries as of last July, though there have been no cases of human bird flu infection to date in the UK.
“We understand that there has been an outbreak of bird flu at a Yorkshire duck farm,” a spokesman for the National Farmers’ Union told the Press Association. “We understand from Public Health England that the risk to public health is very low. DEFRA has introduced a restriction zone and there will be a cull of birds on the farm. We will give any further updates when we have more information.”

Chocolate Shortage Looms – What Are Scientists Doing About It?

Chuck Bednar for redOrbit.com – Your Universe Online
Two of the world’s largest confectioners are warning that global chocolate supplies are running out and there could be a global deficit within the next six years.
According to Washington Post blogger Roberto A. Ferdman, both McLean, Virginia-based Mars Inc. (makers of such treats as M&Ms, 3 Musketeers and Milky Way bars) and Zurich, Switzerland-based Barry Callebaut (the world’s largest chocolate manufacturer) are warning that demand for the products is outpacing supply.
“Chocolate deficits, whereby farmers produce less cocoa than the world eats, are becoming the norm,” Ferdman wrote. “Already, we are in the midst of what could be the longest streak of consecutive chocolate deficits in more than 50 years. It also looks like deficits aren’t just carrying over from year-to-year – the industry expects them to grow.”
Last year, global consumption of cocoa outpaced production by approximately 70,000 metric tons, he explained. By 2020, the two chocolate makers believe the difference could experience a nearly 15-fold increase to one million metric tons, and by 2030 the discrepancy could balloon to more than two million metric tons.
Barry Callebaut said that its sales had increased by 11.7 percent over the past year, according to Dan Bloom of the Daily Mail, but due to what experts are calling the largest cocoa production shortage in five decades, candy companies and chocolatiers claim that they have no choice but to raise prices on their goods.
“The global cocoa sector may suffer a one million metric ton shortfall by 2020 because of increasing economic and environmental pressures on cocoa farms around the world,” the company said, according to Bloom. “Our long-term business depends on a sustainable supply of high quality cocoa, and we believe that securing cocoa’s future begins with increasing yield for the smallholder farmers.”
There are multiple reasons for the phenomenon, explained Ferdman. On the demand side, the increased consumption of chocolate of China and the increased popularity of dark chocolate has led to a shortage, causing cocoa prices to increase by over 60 percent since 2012.
On the supply side, dry weather in regions of West Africa responsible for producing over 70 percent of the world’s cocoa supply has led to decreased production, and a fungal disease known as frosty pod has wiped out an estimated 30 to 40 percent of global crops. Fortunately, scientists are working on a solution to some of these issues.
“To start, the Ivory Coast is planting new hybrid plants called mercedes, which produce more cocoa than average crops,” said Coleen Jose of the website World Mic. “Additionally, a batch of newly introduced strains, the most renowned of which comes from Ecuador, are seeping into the cocoa culture. One breed named CCN-51 is resistant to the frosty pod fungus and produces roughly seven times more beans than its traditional Ecuadorian counterpart.”
Jose notes that CCN-51 comes with one major trade off: taste. Experts have said the taste is on the weak side, and though as Ferdman notes, it is “unclear” if the “milder flavor” will bother consumers, it is clear that “the industry certainly won’t mind, so long as it keeps the potential for a gargantuan shortage at bay.”

Facebook Developing New Social Network For Professionals

Chuck Bednar for redOrbit.com – Your Universe Online
Facebook is reportedly working on a secret new productivity-related website that will allow users to chat with co-workers, connect with their professional colleagues and collaborate on documents online with other users.
As first reported by Hannah Kuchler of the Financial Times on Sunday, the website will be known as “Facebook at Work” and according to what sources told her, it will look to compete with Google Drive and Microsoft Office.
Sources told Kuchler that the website will still look like the traditional Facebook, and will still feature groups and a newsfeed. However, it will allow users to keep their personal and professional files separate from one another.
“Facebook employees have long used the site in their daily work and expanding this to other companies has been discussed internally for some time. The project began in earnest during the past year and is now being tested with companies as its launch approaches,” she said, noting that the social network declined to comment.
As Laura Mandaro of USA Today noted, “A site that would allow users to chat in select groups and collaborate over shared projects would be a direct competitor to… Microsoft’s Office 365 offering, which operates off the cloud,” and that Google Drive’s shared document capabilities and LinkedIn’s focus on connecting users with future jobs, employees and clients could also be seriously challenged by Facebook’s new social network for professionals.
According to Scott Campbell of The Telegraph, the Facebook at Work concept was first discussed earlier this year when media reports surfaced quoting members of the development team as stating they were looking at making work “more fun and efficient” by building an on-the-clock version of the popular social media website.
While it is not clear when Facebook at Work will launch, Campbell said the plan is to release it on the web and mobile platforms (including Android and iOS) and to offer if for free at launch (though that is apparently subject to change). Reuters notes that Facebook’s own employees have already been using the site during their daily work duties for a considerable amount of time, and that it was now being tested with other companies.
“To become an integral part of office life, Facebook will need to win the trust of companies and organizations, which will expect to be able to conduct confidential conversations and share important information on the site, without it falling into the hands of rivals,” Kuchler said. “Many companies, concerned about falling productivity as employees spend work time checking personal messages and internet gossip, currently ban Facebook from the workplace.”
She added that the decision to offer the service for free to begin with “will boost the amount of time spent on the platform, as employees previously banned from using the site in the office may now be encouraged to use it. Facebook generates the vast majority of its revenue from advertising, and the longer people spend on the site, the more opportunities it will have to show adverts.”

Spotters Guide Could Help Astronomers Locate Black Hole Collisions

Chuck Bednar for redOrbit.com – Your Universe Online
A team of UK astronomers has developed what they are calling a “spotters guide” to black holes that, when used in collaboration with observatories due to be activated in the US next year, could help scientists better detect the faint ripples of gravitational waves caused by black holes colliding millions of years ago.
Black holes cannot be seen, the Cardiff University researchers behind the project said, but they can be pinpointed using the Laser Interferometer Gravitational-Wave Observatory (LIGO) once activated in 2015. The new theoretical model could be used to predict all potential gravitational-wave signals which might be found by the detectors, helping astronomers gain new insight into how black holes orbit into each other and collide.
“The rapid spinning of black holes will cause the orbits to wobble, just like the last wobbles of a spinning top before it falls over,” lead investigator Dr. Mark Hannam from the Cardiff University School of Physics and Astronomy said in a statement. “These wobbles can make the black holes trace out wild paths around each other, leading to extremely complicated gravitational-wave signals. Our model aims to predict this behavior and help scientists find the signals in the detector data.”
Dr. Hannam and his Cardiff University co-authors were joined on the project by a team of postdoctoral researchers, PhD students, and collaborators from universities throughout Europe and the US. Essentially, the model they developed shows how black holes distort energy waves around them as they collide, BBC News explained on Friday, and their work could potentially help scientists detect hundreds of black holes.
This new model has already been programmed into the computer codes that LIGO scientists throughout the world will use in their hunt for black-hole mergers once the detectors become activated. Hannam and the members of his team will be working with scientists who hope to use the observatories to unravel the mysteries of the cosmos.
“Sometimes the orbits of these spinning black holes look completely tangled up, like a ball of string. But if you imagine whirling around with the black holes, then it all looks much clearer, and we can write down equations to describe what is happening,” Dr. Hannam said. “It’s like watching a kid on a high-speed spinning amusement park ride, apparently waving their hands around. From the side lines, it’s impossible to tell what they’re doing. But if you sit next to them, they might be sitting perfectly still, just giving you the thumbs up.”
However, he noted there is still much work that needs to be done.
“So far we’ve only included these precession effects while the black holes spiral towards each other. We still need to work out exactly what the spins do when the black holes collide,” the Cardiff researcher explained. “For that they need to perform large computer simulations to solve Einstein’s equations for the moments before and after the collision. They’ll need to produce many simulations to capture enough combinations of black-hole masses and spin directions to understand the overall behavior of these complicated systems.”
A paper outlining the research is published in Physical Review Letters.

Young Children Take But Often Barely Touch Healthy School Cafeteria Food Options

Provided by Stephanie Desmon, Johns Hopkins University Bloomberg School of Public Health
Nearly 6 in 10 put a vegetable on their tray, but only a quarter actually eat even a single bite
You can offer young children healthier food choices in the elementary school cafeteria, but will they actually put it on their trays and eat it?
Probably not, suggests a new Johns Hopkins Bloomberg School of Public Health study.
Researchers observed 274 children in kindergarten through second grade in 10 New York City public schools as they selected from the offerings during one lunch period when a chicken-and-vegetable entrée was on the menu. They watched to see whether each of the six-through-eight-year-olds chose a fruit, vegetable, whole grain, low-fat milk and/or a lean protein, taking before and after photos of the trays. They found that while 75 percent of the kids chose the lean protein (the entrée), only 58 percent chose a fruit and 59 percent chose a vegetable. And among those who put the various types of food on their trays, only 75 percent took even a single bite of the protein, while only 24 percent ate a bite of their vegetables.
“We have been thinking that if young children choose healthy food, they will eat it,” says Susan M. Gross, PhD, MPH, a research associate in the Department of Population, Family and Reproductive Health at the Johns Hopkins Bloomberg School of Public Health. “But our research shows that is not necessarily so.”
Gross is scheduled to present the research at the American Public Health Association’s Annual Meeting in New Orleans, La., on Nov. 17.
She says the environment in the cafeteria had a major impact on whether the children ate their lunches. Along with recording how much food the children selected and ate, the researchers also examined the noise level, supervision level, how full the cafeteria was, the length of the lunch period and the packaging of foods.
They found that children were much more likely to finish their food if a teacher ate in the cafeteria with them. They found that more children ate their vegetables and whole grains when it was quieter in the cafeteria, though noise had little effect on consumption in the other food groups. The children were more likely to eat when their food was cut up into smaller pieces and when lunch periods were longer.
The findings come as Congress prepares in 2015 to reauthorize the Child Nutrition Act, which funds the National School Lunch Program and National School Breakfast Program. Several years ago, new dietary guidelines were adopted by the U.S. Department of Agriculture for school feeding programs requiring schools to provide healthier lunches including whole grains, lean protein and low-fat milk. There was pushback in many circles because mass production of those foods can be more difficult and more costly.
“As much as we are focused on menus in the school lunch program, we need to look more at our cafeteria environments, especially with our youngest children,” Gross says. “We can give kids the healthiest food possible, but if they don’t have time to eat it or they are distracted by how noisy the cafeteria is, they’re not going to eat it. They’re on their own and we need to do as much as possible to help them through that lunch period.”
“Does selection of foods in the school cafeteria by 6-8 year olds translate into consumption? Results of a cafeteria observation study” was written by Susan M. Gross, Allison Zucker, Erin Biehl, Sahnah Lim, Beth Marshall, Marycatherine Augustyn, David M. Paige and Kristin N. Mmari.

Can Wikipedia Be Used To Track Disease Outbreaks?

Chuck Bednar for redOrbit.com – Your Universe Online

Wikipedia page views could help predict potential disease outbreaks weeks before official health advisories are issued, researchers from Los Alamos National Laboratory report in a recently-published study.

Their research, which was published Thursday in the journal PLOS Computational Biology, indicates that they were able to forecast flu and tuberculosis outbreaks four weeks in advance by monitoring articles on the collaboratively-edited online encyclopedia.

Dr. Sara Del Valle and her Los Alamos colleagues said they were able to successfully monitor outbreaks of influenza in the US, Poland, Japan and Thailand, dengue fever in Brazil and Thailand and tuberculosis in China and Thailand. They also said they were able to forecast all but one of those outbreaks at least 28 days in advance.

Their findings suggest that people have the habit of searching websites such as Wikipedia for disease-related information before actually seeking medical attention, and shows the potential for “training” computer models using public health data in one location and then implementing it in another part of the world.

“A global disease-forecasting system will improve the way we respond to epidemics,” Del Valle said in a statement. “In the same way we check the weather each morning, individuals and public health officials can monitor disease incidence and plan for the future based on today’s forecast.”

According to BBC News, Del Valle and her colleagues tracked the page views of disease-related Wikipedia pages from 2010 and 2013. They tracked the languages that the information on those pages was written in, using that as a way to approximate where those individuals lived.

The data was then compared to actual disease outbreak information provided to the research team by various national health surveillance officials. In eight out of 14 cases, the British news organization said that there was a clear increase in page views in the four week period before health officials declared an outbreak.

Furthermore, the model was able to predict every outbreak except the tuberculosis one in China, but as Del Valle explained, “the goal of this research is to build an operational disease monitoring and forecasting system with open data and open source code,” and that their new study “shows we can achieve that goal.”

Others, however, are not so sure. Dr. Heidi Larson of the London School of Hygiene and Tropical Medicine told BBC that the Los Alamos team’s findings were “compelling,” but that she would still be “wary” about using this method as a tool for predicting outbreaks of all types of diseases.

Dr. Larson explained that, in order for this technique to be effective, the individual would have to have Internet access, be literate, understand how Wikipedia works and have knowledge about the condition itself. She also said that other factors could drive people to check Wikipedia, such as a research paper.

In addition, while online trends could provide valuable signals about disease, Dr. Larson said there were still doubts that the data could be used in policy-making or for intervention, especially in some parts of the world. “I’m not sure how much Wikipedia is used in Africa,” she said. “For issues like Ebola, I don’t think people at the beginning of the outbreak in West Africa would have [been searching], because they wouldn’t have had it [Ebola] before.”

Leonid Meteor Shower Expected To Peak Monday

Chuck Bednar for redOrbit.com – Your Universe Online
The Leonid meteor shower, the result of debris left in the orbit of Comet Tempel-Tuttle that hits Earth’s atmosphere each year around mid-November, is expected to peak on Monday.
According to Calla Cofield of Scientific American and Space.com, stargazers living in the US will get their best look at the meteor shower between midnight and dawn on Monday and Tuesday morning, November 17 and 18.
Cofield said that this year’s edition of the meteor shower should produce between 10 and 15 meteors per hour. While that would be a decent rate for many meteor showers, she adds that the Leonids “have a lot to live up to,” as they have been known to produce meteors at a rate of 1,000 or more per hour in previous years.
A shower like that is not expected to occur again for another 20 years, but that doesn’t mean enthusiasts can’t enjoy this year’s version of the Leonids – and Cofield notes that the best way to do so is to go to an area far from city lights, lie flat on your back and look straight up. No special equipment is required, but you might want to dress warmly!
“The Leonids are a reliable annual shower,” EarthSky’s Eleanor Imster explained, noting that the moon “is out of the way” and that Jupiter, the “brightest planet in the nighttime sky now.. is near the Leonid’s radiant point.” She recommended viewing during pre-dawn hours on Tuesday.
Those who don’t want to brave the cold (and possibly snowy) conditions can watch the Leonids from the comfort of their own home by watching live streams from both the NASA’s Meteorite Environment Office and the Slooh Community Observatory, Cofield said. NASA’s broadcast will begin Monday night at 7:30pm EST and will run through sunrise on Tuesday, while the Slooh live stream is scheduled to start at 8:00pm EST on November 17.
Bill Cook, head of the Meteoroid Environment Office, also noted that some experts believe the 2014 Leonids could actually have a second peak, which would occur on Thursday, November 20, Scientific American said. Last year, the meteor shower peaked between November 16 and November 17, Space.com’s Robert Roy Britt reported back in November 2013.
So how are the Leonids produced? Britt explains that every 33 years, Comet Tempel-Tuttle travels around the sun and heads back towards the outer solar system. On each passage across the Earth’s orbit, it releases a trail of debris in a slightly different area than before, and that debris spreads out as time passes.
“Each year, Earth passes through different streams, and different parts of the streams, creating bursts of activity and slack periods in the nights surrounding the event’s peak,” he said, adding that “most of the shooting stars” in the Leonids “are the result of tiny bits of material, the size of sand grains or peas” that blow off the comet and travel through space for centuries at a time. They are vaporized in the atmosphere and never hit the ground, Britt added.
One of the most active Leonid meteor showers took place in 1833, long before scientists fully understood it, the Space.com writer explained. “For several hours… thousands and thousands of meteors at a time rained down,” he said. “That’s more shooting stars in few minutes than you’ll probably see in your whole life.” The phenomenon was so bright it woke people up, and led many to believe that the spectacular light show marked the end of the world.

US Officials Make $425 Million Investment In Supercomputer R&D

Chuck Bednar for redOrbit.com – Your Universe Online
The US Department of Energy announced Friday that it had awarded $425 million for research and the development of next-generation supercomputers at the Oak Ridge and Lawrence Livermore National Laboratories (LLNL).
According to the Wall Street Journal, $325 million of that will be used to install new, cutting-edge supercomputers at the Tennessee and California-based research centers. The machines will utilize Nvidia processors and will be capable of completing calculations between five and seven times faster than the country’s current top computers, officials said.
The supercomputers will be built as part of the CORAL (Collaboration of Oak Ridge, Argonne, and Lawrence Livermore) initiative, which was established earlier this year to leverage supercomputer investments and reduce development costs. The Oak Ridge computer has been dubbed “Summit” and will operate at 150 petaflops, while the LLNL one has been named “Sierra” and will function at 100 petaflops, said Reuters reporter Noel Randewich.
The remaining $100 million will go towards the development of extreme-scale supercomputing technologies as part of the FastForward 2 research and development project, the Department of Energy said in a statement. The goal of FastForward 2 will be “to deliver next-generation capabilities that will enable affordable and energy-efficient advanced extreme scale computing research and development for the next decade.”
“High-performance computing is an essential component of the science and technology portfolio required to maintain U.S. competitiveness and ensure our economic and national security,” said Energy Ernest Secretary Moniz. “We expect that critical supercomputing investments like CORAL and FastForward 2 will again lead to transformational advancements in basic science, national defense, environmental and energy research that rely on simulations of complex physical systems and analysis of massive amounts of data.”
“In an era of increasing global competition in high-performance computing, advancing the Department of Energy’s computing capabilities is key to sustaining the innovation edge in science and technology that underpins US national and economic security while driving down the energy and costs of computing,” the agency added. “The overall goal of both CORAL and FastForward 2 is to establish the foundation for the development of exascale computing systems that would be 20-40 times faster than today’s leading supercomputers.”
Currently, the world’s fastest machine is China’s Tianhe-2 machine, which PC Magazine’s Michael J Miller said has a peak performance of just 54.9 peak petaflops. Furthermore, Miller noted that the total computing power of the 500 most powerful systems as of just a few months ago was only 274 petaflops, while IBM assured him that both Summit and Sierra will have peak performance capabilities that are “well in excess of 100 petaflops.”
Installation of the two computers is expected to begin in 2017, said WSJ reporter Don Clark, and Randewich noted that both domestic researchers and those located throughout the world will be able to apply to use the Summit computer. Sierra, on the other hand, will be used by the National Nuclear Security Administration to ensure that the country’s nuclear arsenal is safe, secure and effective without the need for testing, Nvidia told him.

Autism Researchers Get A Little Help From The Tooth Fairy

Rayshell Clapper for redOrbit.com – Your Universe Online

Every day, across the United States, some little kid loses a tooth, which means every night that same little kid has a magical visit from the tooth fairy who replaces it with money. But what happens to those teeth? Sure, they may be stored away as keepsakes, but that’s a lot of baby teeth for parents to pack away.

Scientifically, there are some serious benefits in studying those teeth. In fact, the Radiation and Public Health Project started a program called the Tooth Fairy Project. This project has participating families send the baby teeth in so that they can study them, specifically looking at elements the teeth have been exposed to since inception. The program looks for Radioactive Strontium-90 (Sr-90) because it is so deadly, and like calcium the body stores it in the bones and teeth indefinitely. Sr-90 will continue to emit cancer-causing radiation, so studying baby teeth will help researchers “accurately determine when and where radioactivity was absorbed from the environment.”

But this is not the only study for which the Tooth Fairy Project has proven to be a benefit. According to the University of California San Diego (UCSD), the Tooth Fairy Project has recently benefited studies on autism. The teeth also go to other researchers, and these scientists “extract dental pulp cells from the tooth and differentiate them into iPSC-derived neurons.”

iPSC – or induced pluripotent stem cells – have implicated a new gene on the autism spectrum disorder (ASD) that falls under the idiopathic category. Idiopathic means non-syndromic autism or autism in which the cause is unknown as defined by the National Human Genome Research Institute. About 85 percent of those who have been diagnosed with autism have idiopathic autism.

The gene discovered by UCSD scientists lead by Alysson Muotri, PhD, associate professor in the UCSD departments of Pediatrics and Cellular and Molecular Medicine, shows an association to Rett syndrome, one of the ASDs, but also supports the idea that different types of ASDs could likely share similar molecular pathways.

As UCSD’s Scott LaFee explains, “The latest findings, in fact, are the result of Muotri’s first tooth fairy donor. He and colleagues identified a de novo or new disruption in one of the two copies of the TRPC6 gene in iPSC-derived neurons of a non-syndromic autistic child. They confirmed with mouse models that mutations in TRPC6 resulted in altered neuronal development, morphology and function. They also noted that the damaging effects of reduced TRPC6 could be rectified with a treatment of hyperforin, a TRPC6-specific agonist that acts by stimulating the functional TRPC6 in neurons, suggesting a potential drug therapy for some ASD patients.”

So, thanks to the tooth fairy, these new findings may help those who have been diagnosed themselves or have a family member diagnosed with an autism spectrum disorder to treat the disorder and cope with the symptoms. By studying the genomics, scientists, doctors, and patients can find greater understandings of the who, what, why and how of genes related to different issues include ASD. Ideally, this can only lead to greater prevention, treatment and healing.

In the words of Dr. Muotri, “I see this research as an example of what can be done for cases of non-syndromic autism, which lack a definitive group of identifying symptoms or characteristics. One can take advantage of genomics to map all mutant genes in the patient and then use their own iPSCs to measure the impact of these mutations in relevant cell types. Moreover, the study of brain cells derived from these iPSCs can reveal potential therapeutic drugs tailored to the individual. It is the rise of personalized medicine for mental/neurological disorders.”

Findings of this study were published in the Nov. 11, 2014 online issue of Molecular Psychiatry.

AT&T To No Longer Insert Tracking Cookies On Your Smartphone

Chuck Bednar for redOrbit.com – Your Universe Online
AT&T Mobility announced on Friday that it would no longer be attaching hidden, unblockable tracking codes to online data transmitted from their customer’s smartphones, various media outlets are reporting.
According to Jack Gillum of the Associated Press (AP), the second-largest cellular provider in the US said that it would be removing a hidden string of numbers and letters transmitted to websites visited by its subscribers.
Those tracking codes “made it nearly impossible to shield its subscribers’ identities online” by tracking their activity across the Internet, Gillum said. The practice is “a lucrative data-mining opportunity for advertisers that could still reveal users’ identities based on their browsing habits,” the AP reporter added.
The use of these codes, which are also known as “perma-cookies,” came to light in late October when it was revealed that AT&T’s rival Verizon Wireless had been quietly inserting a string of approximately 50 letters, numbers and characters into data transmitted from customers to each website they had visited during the past two years.
AT&T’s customer tracking system was known by the name “Relevant Advertising,” and according to MacRumors reporter Juli Clover, it was the result of a pilot program the company had been experimenting with. She added that the company terminated the program in the wake of the negative press such practices received last month.
Verizon referred to their “perma-cookie” code as a “Unique Identifier Header (UIDH),” but experts said that it basically acted like a short-term serial number used by advertisers to identify specific subscribers over the Internet. Unlike AT&T, however, the company told Gillum that they have no plans to discontinue use of the UIDH program.
Verizon spokeswoman Debra Lewis told the AP that the code is not inserted into business and government customers, and that “as with any program, we’re constantly evaluating.” Lewis also noted that subscribers can request their codes not be used for ad-related tracking, but Gillum said the data will still be sent to websites, even if customers explicitly state they do not want their information to be used for marketing purposes.
“The tracking codes are part of the latest plan by the cellular industry to keep tabs on users and their devices,” Gillum said, adding that the codes “don’t explicitly contain personal information” but are “unique and nonetheless sent to websites alongside personal details that a user may submit voluntarily… That means enough data can transform a large chunk of random digits into a digital fingerprint that’s as identifying as a Social Security number.”
“This is more like a license plate for your brain,” Jacob Hoffman-Andrews, a senior staff technologist with the nonprofit digital-rights advocacy group the Electronic Frontier Foundation (EFF), told the AP. “Everything you wonder about, and read, and ask the Internet about gets this header attached to it. And there are ad agencies out there that try to associate that browsing history with anything that identifies you.”
Mobile customers looking to avoid being tracked by these “perma-cookies” could only use their mobile device’s Internet functions while connected to Wi-Fi, though as noted in October by PC World’s Ian Paul, it would be rather inconvenient to avoid wireless networks completely. Alternatively, they could use SSL (HTTPS) encryption while visiting websites, or connecting to the Internet through a virtual private network.

AT&T To No Longer Insert Tracking Cookies On Your Smartphone

AT&T Mobility announced on Friday that it would no longer be attaching hidden, unblockable tracking codes to online data transmitted from their customer’s smartphones, various media outlets are reporting.

According to Jack Gillum of the Associated Press (AP), the second-largest cellular provider in the US said that it would be removing a hidden string of numbers and letters transmitted to websites visited by its subscribers.

Magnetic Field Of Meteorite Provides Clues Of Solar System Formation

Chuck Bednar for redOrbit.com – Your Universe Online
By analyzing a meteorite that crash-landed in India eight decades ago, researchers have discovered the first experimental evidence suggesting that our solar system’s protoplanetary disk was shaped by an intense magnetic field which propelled massive amounts of gas into the sun over the course of just a few million years.
In the study, MIT graduate student Roger Fu and colleagues from Cambridge University, Arizona State University and elsewhere studied a space rock known as a Semarkona, which fell to Earth in northern India back in 1940 and is said to be one of the most pristine relics of the early solar system. They extracted individual pellets known as chondrules from a small sample of the meteorite and measured the magnetic orientations of each grain.
As the study authors reported Friday in the journal Science, they found that the meteorite had not been altered since its formation. With that established, they then measured the magnetic strength of each chondrule and calculated the original magnetic field in which those grains were created. Their calculations revealed the early solar system’s magnetic field was between five and 54 microteslas, or up to 100,000 times stronger than what currently exists in interstellar space.
While astronomers have long observed the process of protoplanetary disk evolution throughout the galaxy, the mechanism by which planetary disks evolved has remained a mystery to scientists for several decades, the researchers said. Based on their measurements, however, the researchers believe that the magnetic field would likely have played a major role in the formation of the solar system and of Earth-like planets.

“Explaining the rapid timescale in which these disks evolve – in only a few million years – has always been a big mystery,” Fu, a graduate student in MIT’s Department of Earth, Atmospheric and Planetary Sciences, said in a statement Friday. “It turns out that this magnetic field is strong enough to affect the motion of gas at a large scale, in a very significant way.”
The chondrules which comprise the Semarkona meteorite would have formed as a result of quick melting events in the solar nebula, the thick cloud of gas and dust that surrounded the newborn Sun, the researchers explained. Regions of the solar nebula would have had to have been heated above the melting point of rock for a period of several hours up to days, causing trapped dustballs to become molten rock, cool and crystallize.
As the pellets cooled, iron-bearing minerals contained within them would have become magnetized by the local magnetic field in the gas, and those properties have been preserved in the chondrules even today. Fu and his colleagues focused specifically on the embedded magnetic fields captured by “dusty” olivine grains that contain abundant iron-bearing minerals, which had a magnetic field of 54 microtesla – similar to that found at Earth’s surface (which varied from 25 to 65 microtesla).
While previous measurements of meteorites suggested that they had magnetic fields of similar strength, it has now been realized that those data had detected magnetic minerals which had been contaminated by Earth’s magnetic field or by hand magnets used by meteorite collectors. The new experiments, the study authors said, use chondrules that had never been measured before, and that they had become magnetized before becoming part of the meteorite.
“The measurements made by Fu and Weiss are astounding and unprecedented,” said co-author Steve Desch of Arizona State University’s School of Earth and Space Exploration. “Not only have they measured tiny magnetic fields thousands of times weaker than a compass feels, they have mapped the magnetic fields’ variation recorded by the meteorite, millimeter by millimeter.”
“The new experiments probe magnetic minerals in chondrules never measured before. They also show that each chondrule is magnetized like a little bar magnet, but with ‘north’ pointing in random directions,” he added, noting that the shock waves traveling through the solar nebula was what melted most of the chondrules, amplifying the background field by as much as 30 times depending on their size and shape. “This is the first really accurate and reliable measurement of the magnetic field in the gas from which our planets formed.”
