Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere. But a new study led by a University of Georgia researcher shows that while the rate of decomposition increases for a brief period in response to warmer temperatures, elevated levels of decomposition don't persist.

An international team of researchers at the University of California, San Diego School of Medicine and the University of Basel in Switzerland have issued a report on the mechanism of toxicity of a chemical compound called Dibutyltin (DBT).

DBT is part of a class of high toxic and widely distributed chemical compounds called organotins, DBT is most commonly used as an anti-fouling agent in paint, for example in the fishing and shipbuilding industries. It is also used in the production of polyvinyl chloride (PVC) plastic tubes and bottles.

The thickness of sea ice in large parts of the Arctic declined by as much as 19% last winter compared to the previous five winters, according to data from ESA's Envisat satellite.

Using Envisat radar altimeter data, scientists from the Centre for Polar Observation and Modelling at University College London (UCL) measured sea ice thickness over the Arctic from 2002 to 2008 and found that it had been fairly constant until the record loss of ice in the summer of 2007. Unusually warm weather conditions were present over the Arctic in 2007, which some scientists have said explain that summer ice loss. However, this summer reached the second-lowest extent ever recorded with cooler weather conditions present. 

Armadillo Aerospace of Rockwall, Texas, earned $350,000 in NASA prize money during the Northrop Grumman Lunar Lander Challenge in Las Cruces, N.M. 

The challenge is a two-level, $2 million competition designed to accelerate commercial space technology and is sponsored by NASA's Centennial Challenges program. After Armadillo's $350,000 first place win for level one this year, $1.65 million remains as available prize money for future competitions. 

It seems not everyone can forget the "Friends" television show.   Angelina Jolie may have gotten Brad Pitt but Jennifer Aniston is the one with her own namesake neuron.

Professor Rodrigo Quian Quiroga, neuroscientist and bio-engineer, whose research was recently cited among the top papers in the world, is to reveal details of his studies into what has been dubbed the ‘Jennifer Aniston neuron’ during a public presentation at the University of Leicester.

Political polls show Barack Obama ahead in the minds of confirmed voters but a nebulous grey area, the 'undecided' voter, coupled with margin of error, means anything can happen

Political parties spend a great deal of money trying to appeal who declare themselves undecided and there is a great deal of research that goes into figuring them out. The biggest question for psychologists; do undecided voters actually make their choices before they realize? University of Virginia psychology professor Brian Nosek and colleagues set out to find an answer.
