Misinformation Can Spread Like Wildfire On Twitter
2014-03-19 05:40:39

redOrbit Staff & Wire Reports - Your Universe Online Twitter can be enormously helpful during an emergency, but it can be just as detrimental when misinformation is rapidly spread during a crisis. Researchers from University of Washington studied last year’s Boston Marathon bombings and found that significant amounts of misinformation spread widely on Twitter despite efforts by users to correct rumors that were inaccurate. The bombings, which took place on April 15, 2013 when...

Scientists Build Thinnest-possible LEDs To Be Stronger And More Energy Efficient
2014-03-11 08:26:27

[ Watch The Video: Extracting Two-Dimensional Materials ] Michelle Ma, University of Washington Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy efficient. University...

Exoplanet Atmospheres

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is the search for a potentially habitable planet, or even better, one that is shown to already contain life. There are various parameters that are needed in order to ascertain the habitability of worlds, such as whether liquid water can be sustained on its surface. Recent studies, however, have found that identifying some of these characteristics is rather difficult, and we may in fact...

Battery-free Technology Brings Gesture Recognition System To Electronics
2014-03-03 09:59:42

[ Watch The Video: AllSee: Bringing Gesture Recognition to All Devices ] Michelle Ma, University of Washington Mute the song playing on your smartphone in your pocket by flicking your index finger in the air, or pause your “This American Life” podcast with a small wave of the hand. This kind of gesture control for electronics could soon become an alternative to touchscreens and sensing technologies that consume a lot of power and only work when users can see their smartphones and...

when a pine-scented molecule combines with ozone in the surrounding air, some of the free radicals created in the process grab oxygen with unprecedented speed
2014-02-27 06:28:35

April Flowers for redOrbit.com - Your Universe Online For atmospheric scientists, pine forests are magical places where coniferous trees give off pine-scented vapors. These vapors form particles, rapidly and seemingly out of nowhere. A new study from an international group of scientists illuminates the process by which gas wafting from coniferous trees creates particles that can reflect sunlight or promote cloud formation. Both are important climate feedbacks. The findings, led by the...

Hannah Hickey, University of Washington The phrase, 'Eat your vitamins,' applies to marine animals just like humans. Many vitamins, including B-12, are elusive in the ocean environment. University of Washington researchers used new tools to measure and track B-12 vitamins in the ocean. Once believed to be manufactured only by marine bacteria, the new results show that a whole different class of organism, archaea, can supply this essential vitamin. The results were presented Feb. 24 at...

Credit Card-sized Device Could Analyze Biopsy And Help Diagnose Pancreatic Cancer In Minutes
2014-02-07 13:01:23

University of Washington Pancreatic cancer is a particularly devastating disease. At least 94 percent of patients will die within five years, and in 2013 it was ranked as one of the top 10 deadliest cancers. Routine screenings for breast, colon and lung cancers have improved treatment and outcomes for patients with these diseases, largely because the cancer can be detected early. But because little is known about how pancreatic cancer behaves, patients often receive a diagnosis when...

Fruit Flies Are Relentless Party Crashers
2014-02-05 13:30:09

University of Washington That fruit fly joining you just moments after you poured that first glass of cabernet, has just used its poppy-seed-sized brain to conduct a finely-choreographed search, one that’s been described for the first time by researchers at the University of Washington. The search mission is another example of fruit flies executing complex behaviors with very little “computational” power, their brains having 100,000 neurons compared to house flies with 300,000...

Complications From Facelifts Eased With Help Of New 3-D Imaging Technique
2014-01-28 11:47:02

University of Washington Millions of people each year remove wrinkles, soften creases and plump up their lips by injecting a gel-like material into their facial tissue. These cosmetic procedures are sometimes called “liquid facelifts” and are said to be minimally invasive. It’s rare, but sometimes things go wrong. In a matter of minutes, patients’ skin can turn red or blotchy white and the injected area becomes painful. Vital blood supply to the face is restricted and if...

Study Shows Rock Can Turn Into Soil Faster Than Previously Thought
2014-01-17 11:09:55

University of Washington Geologic time is shorthand for slow-paced. But new measurements from steep mountaintops in New Zealand show that rock can transform into soil more than twice as fast as previously believed possible. The findings were published Jan. 16 in the early online edition of Science. "Some previous work had argued that there were limits to soil production," said first author Isaac Larsen, who did the work as part of his doctoral research in Earth sciences at the...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
