Keeping the flu away: Synthetic protein activates immune system within two hours Posted: 06 Jul 2012 08:47 PM PDT Researchers may have found the secret to helping the immune system fight off the flu before it gets you sick. A new study finds that EP67, a powerful synthetic protein, is able to activate the innate immune system within just two hours of being administered.

Heat, rainfall affect pathogenic mosquito abundance in catch basins Posted: 06 Jul 2012 01:55 PM PDT Rainfall and temperature affect the abundance of two mosquito species linked to West Nile Virus in storm catch basins in suburban Chicago, researchers report.

Arctic warming linked to combination of reduced sea ice and global atmospheric warming Posted: 06 Jul 2012 01:42 PM PDT The combination of melting sea ice and global atmospheric warming are contributing to the high rate of warming in the Arctic, where temperatures are increasing up to four times faster than the global average, a new study has shown.

Spaceflight may extend the lifespan of microscopic worm Posted: 06 Jul 2012 07:55 AM PDT The effect of spaceflight on a microscopic worm -- Caenorhabditis elegans (C. elegans) -- could help it live longer. The discovery was made by scientists studying the loss of bone and muscle mass experienced by astronauts after extended flights in space.

Increased growth responsible for color changes in coral reefs Posted: 06 Jul 2012 07:54 AM PDT New insight has been provided into the basic immune response and repair mechanisms of corals to disease and changing environmental conditions. The study found that increased growth is the underlying physiological process associated with disease, wounding and stress-related color changes in reef-building corals.

How bacteria sense salt stress Posted: 06 Jul 2012 07:54 AM PDT Scientists' finding is a major breakthrough in understanding a decades-old problem of how bacteria detect environmental changes.

Stop and go: ‘Traffic officer’ protein directs crucial step in cell division Posted: 06 Jul 2012 07:54 AM PDT A traffic officer standing at a busy intersection directing the flow of vehicles may be a rare sight these days, but a similar scene appears to still frequently play out in our cells. A protein called Lem4 directs a crucial step of cell division by preventing the progress of one molecule while waving another through, scientists have found.

First 'bottom-up' estimates of China's CO2 emissions Posted: 06 Jul 2012 07:54 AM PDT Atmospheric scientists have produced the first "bottom-up" estimates of China's carbon dioxide (CO2) emissions, for 2005 to 2009, and the first statistically rigorous estimates of the uncertainties surrounding China's CO2 emissions.
