Without aggressive action to reduce soot emissions, the time table for carbon dioxide emission reductions may need to be significantly accelerated in order to achieve international climate policy goals such as those set forth in last December's Copenhagen Accord, according to 'Assessing the climatic benefits of black carbon mitigation,' a study published online June 21 in the Proceedings of the National Academy of Sciences (PNAS)…
A mechanism that regulates stem-cell differentiation in mice testes suggests a similar process that may trigger degenerative disease in humans, according to a Penn State College of Agricultural Sciences reproductive physiologist…
Celia has exploded into a monster hurricane in the Eastern Pacific, and is now a Category 5 storm over open waters. NASA's Aqua satellite captured an infrared image (that shows temperature) of Celia's clouds and clearly shows an eye in the storm. Celia's eye appears well-defined and is between 15-20 nautical miles wide…
There are now two major hurricanes in the Eastern Pacific Ocean and they appear to be chasing each other in imagery from the GOES-13 satellite. Hurricane Celia is a Category Five hurricane on the Saffir-Simpson Scale, and Hurricane Darby to Celia's east has just become a Category Three hurricane (a major hurricane)…
What determines plant diversity in a forest? It's a question even Charles Darwin wanted to unravel. But most research into forest diversity demonstrates only patterns of species survival and abundance rather than the reason for them - until now…
Using an experimental mouse model for malaria, an international group of scientists has discovered that adding antioxidant therapy to traditional antimalarial treatment may prevent long-lasting cognitive impairment in cerebral malaria. Their findings were published online June 24, 2010, in the journal PLoS Pathogens…
Two actors wrapped in motion sensors circle each other, as engineering researchers stand at the perimeter of a USC Viterbi School of Engineering laboratory, taking note…
The University of Southampton has played a key role in a major new piece of research that challenges the belief that the biggest charities are becoming increasingly dominant in financial terms - a development sometimes known as 'Tescoisation.'…
On Sunday, NASA's historic Deep Impact spacecraft will fly past Earth for the fifth and last time on its current University of Maryland-led EPOXI mission. At time of closest approach to Earth, the spacecraft will be about 30,400 kilometres (18,900 miles) above the South Atlantic…
