Strongly interacting Fermi condensates are put on trial Feb 2
An experimental technique that can test theories of strongly-interacting Fermi condensates has been developed in Austria. Physicists made precise time measurements of oscillations in the condensates to show that Monte Carlo simulations are the only current method available for accurately revealing their behaviour in the puzzling "BEC-BCS crossover" regime (Phys. Rev. Lett 98 040401).
Mankind to blame for global warming says IPCC Feb 2
The burning of fossil fuels and other human endeavours are causing global warming, says a major scientific report released today by the Intergovernmental Panel on Climate Change (IPCC). Written by about 600 climate experts, the UN-backed report also concluded that global warming is causing sea levels to rise and will bring drought and other extreme weather to many parts of the globe. The report, which is the IPCC's most forceful statement to date backing the scientific validity of manmade climate change, also warns that it may be too late to stop global warming by stabilizing greenhouse gas emissions.
Tiny mass detectors come out of the cold Feb 2
Physicists in the US have made the first "nanocantilever" that can measure extremely small masses under everyday conditions – unlike previous devices that needed a high vacuum or cryogenic temperatures to work. The result, which comes from Michael Roukes and colleagues at the California Institute of Technology, could revolutionize the way the masses of tiny particles are measured.
