In the March 2007 issue of BioScience, an international team of 19 researchers calls for better forecasting of the effects of global warming on extinction rates. The researchers, led by Daniel B. Botkin, note that although current mathematical models indicate that many species could be at risk from global warming, surprisingly few species became extinct during the past 2.5 million years, a period encompassing several ice ages. They suggest that this "Quaternary conundrum" arises because the models fail to take adequate account of the mechanisms by which species persist in adverse conditions.

A 17-year University of Utah study of ground movements shows that the power of the huge volcanic hotspot beneath Yellowstone National Park is much greater than previously thought during times when the giant volcano is slumbering.

Researchers at Yale have identified multiple pathogenic "alien islands" in the genome of the A. baumannii, bacteria that has been responsible for new and highly drug-resistant infections in combat troops in the Middle East, according to a report in the March 1 issue of Genes and Development.

"Drug resistant bacterial infections are a rapidly growing problem in hospital settings, and now in difficult conditions of combat. We targeted A. baumannii as a growing threat for our troops in Iraq," said s principal investigator Michael Snyder, the Lewis B Cullman Professor of Molecular Cellular & Developmental Biology.

During Rosetta's recent Mars swingby, the OSIRIS cameras captured a series of images of Mars and of Phobos transiting Mars' disk. The OSIRIS team have produced a cool animated sequence and a 3D view of the Red Planet.

The animated sequences (one faster, one slower) show the shadow of Phobos transiting Mars' disk on 24 February; the images were captured around 22:08 CET, a few hours prior to Rosetta's successful Mars swingby on 25 February.

Researchers have used the world's thinnest material to create the world's smallest transistor – a breakthrough that could spark the development of a new type of super-fast computer chip.

Professor Andre Geim and Dr Kostya Novoselov from The School of Physics and Astronomy at The University of Manchester, reveal details of transistors that are only one atom thick and less than 50 atoms wide, in the March issue of Nature Materials.

They believe this innovation will allow the rapid miniaturisation of electronics to continue when the current silicon-based technology runs out of steam.

In recent decades, manufacturers have crammed more and more components onto integrated circuits.

Among the central mysteries of neurobiology is what properties of the young brain enable it to so adeptly wire itself to adapt to experience—a quality known as plasticity. The extraordinary plasticity of the young brain occurs only during a narrow window of time known as the critical period.
