Methane sources over the last 30,000 years
Using novel isotopic studies, scientists from the European Project for Ice Coring In Antarctica were now able to identify the most important processes responsible for changes in natural methane concentrations over the transition from the last ice age into our warm period. The study now published in the scientific magazine nature shows that wetland regions emitted significantly less methane during glacial times. In contrast methane emissions by forest fire activity remained surprisingly constant from glacial to interglacial times. (2008-04-16)

The theorists analyzed two years of biocomputation and simulation to uncover a surprisingly simple mechanism describing how this protein fragment penetrates the cell membrane. The discovery could help scientists treat other human illnesses by exploiting the same molecules that make HIV so deadly proficient. (2008-01-17)

North Atlantic warming tied to natural variability; but global warming may be at play elsewhere
A Duke University-led analysis of available records shows that while the North Atlantic Ocean's surface waters warmed in the 50 years between 1950 and 2000, the change was not uniform. In fact, the subpolar regions cooled at the same time that subtropical and tropical waters warmed. (2008-01-03)

In search for water on Mars, clues from Antarctica
Scientists have gathered more evidence that suggests flowing water on Mars -- by comparing images of the red planet to an otherworldly landscape on Earth. In recent years, scientists have examined images of several sites on Mars where water appears to have flowed to the surface and left behind a trail of sediment. Those sites closely resemble places where water flows today in the McMurdo Dry Valleys in Antarctica , the new study has found. (2007-12-09)

Aurora Borealis breaks new grounds -- and old ice
It can crush ice sideways and stay precisely on station to an accuracy of a metre. It can drill a hole 1,000 meters deep into the seabed while floating above 5,000 meters of ocean and it can generate 55 megawatts of power. So far, Aurora Borealis is the most unusual ship that has never been built, and it represents a floating laboratory for European science, a breakthrough for polar research and a very big headache for international lawyers.
