British Atlantic Survey -- Large colonies of micro-organisms living under rocks have been discovered in the most hostile and extreme regions of the Arctic and Antarctic Ã¢ÂÂ giving new insights on survival of life on other planets.     Reporting in this week's Nature, scientists from British Antarctic Survey (BAS) and Scripps Institution of Oceanography reveal their surprise findings that rock-dwelling micro-organisms can photosynthesise and store carbon just as much as the plants, lichens and mosses that live above ground...

There's new evidence from an Antarctic ice core that the popular image of the melting poles doesn't quite fit reality at the southern one. Elizabeth R. Thomas of the British Antarctic Survey and colleagues report in Geophysical Research Letters that snow accumulation has doubled since 1850 in the western Antarctic peninsula, and that the trend [...].

Astronomers using a giant telescope atop a volcano have discovered a hot spot at the tip of Saturn's south pole. The infrared images captured by the Keck I telescope at the W.M. Keck Observatory atop Mauna Kea on the Big Island suggest a warm polar vortex &#151; a large-scale weather pattern likened to a jet stream on Earth that occurs in the upper atmosphere. It's the first such hot vortex ever discovered in the solar system.
