USC (US) - Scientists have discovered tiny, filamentous bacteria that link up like living power cables to transmit electrons thousands of cell lengths away. The Desulfobulbus bacterial cells, which are only a few thousandths of a millimeter long each, are so tiny that they are invisible to the naked eye.

PRINCETON (US) - "Is evolution predictable? To a surprising extent the answer is 'yes'," says Princeton professor Peter Andolfatto. New research by Andolfatto and colleagues published in the journal suggests that knowledge of a species' genes-and how certain external conditions affect the proteins encoded by those genes-could be used to determine a predictable evolutionary pattern driven by outside factors.

By Gretchen Cuda Kroen Frozen water droplets take on a whole new shape when they freeze: Instead of staying round, they form a pointy tip, and eventually sprout a tiny forest of ice crystals on their surface. In order to observe these effects, researchers dripped tiny beads of water on a plate kept at a chilly -20°C.

Alaska and other plaintiffs that include hunters and the California Cattlemen's Association are appealing a federal court ruling last year that upheld the Interior Department's 2008 designation of the bears as threatened because their icy habitat is melting away. Murray Feldman, a lawyer for Alaska and other appellants, told the U.S.

By Alister Doyle OSLO (Reuters) - Pesticides used in farming are also killing worker bumblebees and damaging their ability to gather food, meaning colonies that are vital for plant pollination are more likely to fail when they are used, a study showed on Sunday.
