Sunlight May Help Lower Blood Pressure
2014-01-20 13:00:15

University of Southampton Exposing skin to sunlight may help to reduce blood pressure and thus cut the risk of heart attack and stroke, a study published in the Journal of Investigative Dermatology suggests. Research carried out at the Universities of Southampton and Edinburgh shows that sunlight alters levels of the small messenger molecule, nitric oxide (NO) in the skin and blood, reducing blood pressure. Martin Feelisch, Professor of Experimental Medicine and Integrative Biology...

Gerard LeBlond for redorbit.com - Your Universe Online Tanning beds have been used commercially for decades and according to a new study published in JAMA Dermatology, an estimated one million people use them daily. Use of these beds has been considered a high cancer risk and their use is being restricted in many states. Indoor tanning has been linked to melanoma and non-melanoma skin cancer, mainly before the age of 35. Forty percent of teenage girls use tanning beds and about 20...

Seasonal Depression typically begins in fall and ends in spring. Evans, GA (PRWEB) December 20, 2013 Seasonal depression, often called seasonal affective disorder (SAD), occurs each year at the same time, usually starting in fall, worsening in winter, and ending in spring. It is more than just "the winter blues" or "cabin fever." A rare form of SAD, known as "summer depression," begins in late spring or early summer and ends in fall. The Center for Primary...

New Instrument Continues To Gather Effects Of The Sun On Earth
2013-12-05 15:56:22

NASA Maintaining a record of solar measurements is important in understanding the sun's effect on Earth and the National Oceanic and Atmospheric Administration's (NOAA), Total solar irradiance Calibration Transfer Experiment, or TCTE, is now providing that information. Many natural conditions on Earth such as the surface temperature or air temperature depend on energy that comes from the sun in the form of electromagnetic radiation. A solar cycle lasts about 11 years and typically has...

Research on less-studied but ever-present UVA1 rays shows just two daily exposures can start skin-aging process A low level of daily exposure to a common component of sunlight can cause skin damage at the molecular level after just a few days, new University of Michigan Medical School research shows. The findings highlight the need for better sunscreens to protect against these damaging rays, and prevent the process that can cause skin to look old, wrinkled and sagging prematurely....

At some point, mostly everyone has spent a little too much time in the sun on a sunny winter vacation and experienced the painful reality of sunburn. The Joint Canadian Tanning Association (JCTA) wants to help reduce that risk. Kelowna, BC (PRWEB) November 29, 2013 At some point, mostly everyone has spent a little too much time in the sun and experienced the painful reality of sunburn. Even if it’s not a bad burn, it’s uncomfortable in the short term and definitely not good for your...

The University of Geneva, Switzerland, has generated UV-resistant transgenic plants which produce high levels of antioxidants Plants have a love-hate relationship with sunlight. While some wavelengths are indispensable to them for performing photosynthesis, others, such as UV-B, are deleterious. Therefore, plants are equipped to detect these highly toxic rays and mount their defenses. A team led by Roman Ulm, Professor at the Faculty of Sciences at the University of Geneva (UNIGE),...

Study results may help predict plant responses to light, temperature Shade nets are widely used in ornamental crop production systems to protect crops from radiation, wind, hail, and birds. According to a 2011 study from the United States Department of Agriculture, 43% of floricultural crop production in the United States occurred under shade or other temporary cover. Although black nets are most common, growers have begun experimenting with colored, gray, and white "dispersive" netting in...

Incoming Solar Radiation Impacts By Various Weather Cycles
2012-08-22 13:30:39

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...

Incoming Solar Radiation Impacts By Various Weather Cycles

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Sunglasses are protective eyewear designed to shield the eyes from damaging or discomforting sunlight and high-energy light. They can also work as a visual aid. The ultraviolet radiation from the sun can cause several serious eye problems and many healthcare professionals recommend eye protection. However, since the 1940s sunglasses have been associated with celebrities more so than eye protection. James Ayscough experimented with tinted lenses in the mid-18th century although they were...
