New Depiction of Light Could Boost Telecommunications Channels
Physicists with the Institute of Ultrafast Spectroscopy and Lasers (IUSL) at The City College of New York have presented a new way to map spiraling light that could help harness untapped data channels in optical fibers. Increased bandwidth would ease the burden on fiber-optic telecommunications networks taxed by an ever-growing demand for audio, video and digital media. The new model, developed by graduate student Giovanni Milione, Professor Robert Alfano and colleagues, could even spur enhancements in quantum computing and other applications.

Free Radicals Crucial to Suppressing Appetite
Obesity is growing at alarming rates worldwide, and the biggest culprit is overeating. In a study of brain circuits that control hunger and satiety, Yale School of Medicine researchers have found that molecular mechanisms controlling free radicals -- molecules tied to aging and tissue damage -- are at the heart of increased appetite in diet-induced obesity.

Preserving 4 Percent of the Ocean Could Protect Most Marine Mammal Species, Study Finds
Preserving just 4 percent of the ocean could protect crucial habitat for the vast majority of marine mammal species, from sea otters to blue whales, according to researchers at Stanford University and the National Autonomous University of Mexico.

Panda Poop May Be a Treasure Trove of Microbes for Making Biofuels
Panda feces contains bacteria with potent effects in breaking down plant material in the way needed to tap biomass as a major new source of "biofuels" produced not from corn and other food sources, but from grass, wood chips and crop wastes, scientists reported in Denver at the 242nd National Meeting & Exposition of the American Chemical Society (ACS).

Discovery Sheds Light On the Ecosystem of Young Galaxies
A team of scientists, led by Michael Rauch from the Carnegie Observatories, has discovered a distant galaxy that may help elucidate two fundamental questions of galaxy formation: How galaxies take in matter and how they give off energetic radiation.

Bedrock Nitrogen May Help Forests Buffer Climate Change, Study Finds
For the first time, researchers at the University of California, Davis, have demonstrated that forest trees have the ability to tap into nitrogen found in rocks, boosting the trees' growth and their ability to pull more carbon dioxide from the atmosphere.

'Gene Overdose' Causes Extreme Thinness
Scientists have discovered a genetic cause of extreme thinness for the first time, in a study published August 30 in the journal Nature. The research shows that people with extra copies of certain genes are much more likely to be very skinny. In one in 2000 people, part of chromosome 16 is duplicated, making men 23 times and women five times more likely to be underweight.
