An ultra-high-resolution imaging technique using X-ray diffraction is a step closer to fulfilling its promise as a window on nanometer-scale structures in biological samples. In the Proceedings of the National Academy of Sciences, researchers report progress in applying an approach to "lensless"... Read More
An article published online first and in an upcoming edition of The Lancet reports that identification of sepsis-causing bacteria using a new microarray platform is highly accurate and delivers results an average of eighteen hours faster than the current gold-standard system. It uses techniques ... Read More
Scientists studying how bacteria under stress collectively weigh and initiate different survival strategies say they have gained new insights into how humans make strategic decisions that affect their health, wealth and the fate of others in society.

The first comprehensive study of pandemic H1N1 influenza from April to the end of July indicates that the pandemic may be the mildest ever, assuming that the virus doesn't mutate during the winter and come back stronger than before. The analysis suggests that the swine flu virus might directly c... Read More
The 2009 H1N1 influenza virus used a new strategy to cross from birds into humans, a warning that it has more than one trick up its sleeve to jump the species barrier and become virulent.
In a report in the journal Proceedings of the National Academy of Sciences, University of California, Ber... Read More
Made from a hodgepodge of genetic bits and pieces, the newly discovered Marseillevirus is the world’s largest virus.
But fame is fleeting: It’s almost sure to be supplanted by another, even bigger virus. What’s really special about Marseillevirus is where it comes from. Like other giant virus... Read More
