Dispute Over Life In Antarctic Lake - SpaceDaily  Left:  'It'd be bigger news if Lake Vostok were found to be sterile'  Controversy has erupted over Lake Vostok, one of Earth's last unexplored frontiers, which lies deep under the Antarctic ice. Last week a team of Russian and French scientists claimed the lake is sterile. But American scientists insist that it is a potential source of undiscovered life forms, and are worried that Russian plans to drill right through the ice will contaminate it. At the heart of the dispute is a small but diverse group of microbes found in the single core that has been drilled from the ice above the lake. The Russians and French say these are contaminants from the drilling and testing of samples in the labs.  
World's Smallest Autonomous Submarine - SpaceDaily  Left:  The Serafina is 40 centimetres long, with five propellers and a plastic hull crammed with rechargeable batteries and circuitry. The craft is able to travel at a relatively fast underwater speed of one metre per second equivalent to fast walking pace but can also hover, tilt and right itself if overturned.  Most importantly, the team have managed to refine the design so Serafina can be produced relatively cheaply - starting at around A$1,000 per basic unit. This raises the potential for large numbers of Serafinas to be deployed, travelling together in swarm formation, like a school of fish. "Small and versatile submersibles, such as Serafina, are an important leap towards making underwater exploration affordable and effective.

NASA Selects Proposals To Study Global Carbon Cycling - SpaceDaily  NASA, in partnership with the Department of Agriculture and Department of Energy, recently awarded 59 research grants to study changes in the distribution and cycling of carbon among land, ocean, and atmospheric reservoirs, with emphasis on North America. These new research activities are funded as part of the U.S. Climate Change Science Program (CCSP). The global carbon cycle affects Earth's climate. Of special interest are factors that control changes in atmospheric carbon dioxide and methane concentrations.
