Green tea may help protect against autoimmune disease, Medical College of Georgia researchers say.

Researchers studied an animal model for type I diabetes and primary Sjogren's Syndrome, which damages the glands that produce tears and saliva.

There's a "First Light Fiesta" in the works at Mt. Hopkins near Amado, Ariz. And Iowa State University astrophysicists will be among those enjoying the celebration of a new telescope system and all the science it will produce.

The global search for a sustainable energy supply is making significant strides at Wake Forest University as researchers at the university's Center for Nanotechnology and Molecular Materials have announced that they have pushed the efficiency of plastic solar cells to more than 6 percent.

Wake Forest researchers describe how they have achieved record efficiency for organic or flexible, plastic solar cells by creating "nano-filaments" within light absorbing plastic, similar to the veins in tree leaves. This allows for the use of thicker absorbing layers in the devices, which capture more of the sun's light.

A few days ago we told you about the new hydrothermal vent named Medusa.

They chose that name because that name because they also found a unique pink form of the jellyfish order stauromedusae.

The bell-shaped jellyfish sighted near the vents may be of a new species "because no one has seen this color before," said Karen Von Damm, a geologist at the University of New Hampshire.

The first phase of a caloric restriction study in human subjects found evidence that calorie-restricted diets differing substantially in glycemic load can result in comparable long-term weight loss. In other words, calories matter more than carbohydrates.

The study, at the Jean Mayer US Department of Agriculture Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University and part of the multi-center Comprehensive Assessment of Long-term Effects of Restricting Intake of Energy (CALERIE) trial, accounted for dietary factors that affect hunger and satiety, used laboratory techniques to measure adherence, and was the first of its kind to provide a complete set of meals and snacks to its participants.

Yes, a television broadcast on global warming is going to highlight the one section of the planet that is not warming.

Stephen Padin, the South Pole station science leader, will be featured on the ABC broadcast "Planet Earth 2007: Seven Ways to Help Save the World." Padin is spending the southern winter at the world's most remote scientific observatory.
