A yeast named Candida glabrata commonly occurs in humans, usually on our skin. It does little harm there. But if it enters the blood system, it can be directly…
The findings have important implications for biologists and geneticists using C. elegans for their research. Until recently scientists have largely limited…
The International Polar Year (IPY) concluded in March 2009 with a tangible legacy in the form of a network of databases on marine biodiversity that will serve…
A new study published as the cover article for the April 2009 issue of The FASEB Journal promises to give physicians new ways to reduce deadly responses to…
