New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosyste

National Science Foundation-funded scientists working in an ice-free region of Antarctica have discovered the last traces of tundra--in the form of fossilized plants and insects--on the interior of the southernmost continent before temperatures began

Scientists in Illinois and Pennsylvania are reporting development of a way to make the antifreeze protein that enables billions of Canadian snow fleas to survive frigid winter temperatures.

By KENNETH CHANG. Researchers working on a NASA mission to understand the interplay of magnetic fields and charged particles blown outward from the Sun have identified the trigger for the colorful electrical storms in the polar regions.

"The machine is different from all the other projects that aim to derive energy out of waves. It can be used in a calm sea as the Mediterranean, even if its efficiency in the ocean could be five times bigger" Grassi said.

Coat color of wild and domestic animals is a critical trait that has significant biological and economic impact. Researchers have now identified the genetic basis for black coat color, and white, in a breed of domestic sheep.

Scientists have devised an efficient and practical solar power device they believe will make the renewable energy source more affordable. They used glass sheets coated in organic dyes to concentrate light hitting the panes.
