Ever the cagey foe, Salmonella has been around for millions of years and has managed to beat thousands of attempts to eradicate it. An amazingly “smart” and resilient germ but always totally ruthless, Salmonella and its more than 2,500 different strains are always looking for new ways to survive... Read More
Swine flu no longer represents a major threat to the U.S. population, because most people are immune to the virus that caused last season's pandemic, health officials report Tuesday.
Of the 310 million people in the USA, 59% are now believed to be immune to pandemic H1N1 flu, the researchers ... Read More
Amyloid protein structures are best known for the troubles they pose in the brains of Alzheimer's patients. Now researchers are trying to exploit their presence in a very different place – in semen – to find a new way to stop HIV.
Scientists have created a substance that targets amyloid struc... Read More
Abstract - A crucial transition in the origin of life was the emergence of an informational polymer capable of self-replication and its compartmentalization within protocellular structures. We show that the physicochemical properties of ice, a simple medium widespread on a temperate early Earth,... Read More

The 2009 swine flu virus faces two probable fates: it will either continue to cause low or moderate mortality or it will go extinct. That’s the judgment of the authors of a new Perspectives piece in mBio, which points out that the impact of the virus this flu season will depend largely on the d... Read More
