The concept of delaying global warming by adding particles into the upper atmosphere to cool the climate could unintentionally reduce peak electricity generated by large solar power plants by as much as one-fifth, according to a new NOAA study. The findings appear in this week's issue of Environmental Science and Technology."Injecting particles into the stratosphere could have unintended consequences for one alternative energy source expected to play a role in the transition away from fossil...

Canopy light interception (LI) is an important factor for crop growth and fruit yield. Crop yield depends on a canopy's ability to intercept incident solar radiation, which in turn depends on the available leaf area, its structure, and its efficiency in the process of photosynthesis.Maximizing leaf growth through light interception is an important consideration when studying different agricultural or environmental factors on crop yield, and it is the main source of data in the most widely...
A leading expert said today that people with "seasonal affective disorder", or SAD, cannot be cured with tanning. The condition, also known as "winter depression" or "winter blues" in its less severe form, is often treated with daily sessions of exposure to bright light. And while some reports have linked tanning to improvements in mood, real light therapy uses a completely differently type of light and works through the eyes, a Reuters report quoted Dr....

Some people sneeze when they think about sex, have a full stomach or walk into sunlight, says a British doctor who investigated sneezing phenomena. It certainly seems odd, but I think this reflex demonstrates evolutionary relics in the wiring of a part of the nervous system called the autonomic nervous system, said Dr. Mahmood Bhutta, an ear, nose and throat specialist at John Radcliffe Hospital in Oxford. Sneezing caused by sexual thoughts may be under-reported because people are...
Solar panels may gain a boost in ability to capture the sun's rays thanks to a newly developed reflective coating.Researchers at Rensselaer Polytechnic Institute in Troy, New York say the new coating allows solar panels to soak up 96.2 percent of sunlight.Current solar panels -- which convert energy from the sun into electricity -- absorb only about two-thirds of available sunlight."That is a tremendous savings," Rensselaer's Shawn-Yu Lin, whose study appears in the journal Optics...
By Bacqueville, Daniel Mavon, Alain ABSTRACT In the present study, a convenient and easy-to-handle skin organ culture was developed from domestic pig ears using polycarbonate Transwell(R) culture inserts in 12-well plate. This alternative model was then tested for its suitability in analyzing the shortterm effects of a single solar radiation dose (from 55 to 275 kJ m^sup -2^). Differentiation of the pig skin was maintained for up to 48 h in culture, and its morphology was similar to that of...
Alternative energy is more than a popular buzzword for pupils at Sego Middle School. Because of a $20,000 solar panel provided by Georgia Power, Sego is one of fewer than a dozen schools in the state where pupils are learning hands-on lessons about capturing light from the sun and turning it into energy. "It's opened a whole world to them they didn't know existed," Assistant Principal Sonya Bailey said. The solar panel was erected in one of Sego's courtyards in the spring and became...
By ELIZABETH McMEEKIN This week: Vitamin D Scientist and writer Oliver Gillie has found that a lack of sunshine - and a lack of vitamin D as a result - contributes to Scotland's higher rates of diabetes, high blood pressure, cancer, cardiovascular disease and multiple sclerosis (MS). What about our bad diet, alcohol problems and genetics? Don't they have something to do with it as well? While cancer and heart disease can come as a result of many factors, including genetic predisposition...

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...
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...
