Bioinformatics technology provides new insight into microbial activities (3/15/2008)

Scientists may gain a new insight into the relationship between viruses and their environments thanks to a new computational technology developed by researchers at the U.S. Department of Energy's Argonne National Laboratory. This technology has already been used to identify subtle differences in the metabolic processes of microbial communities. ...> Full Article

Short RNA strand helps exposed skin cells protect body from bacteria, dehydration and even cancer (3/4/2008)

Every minute, 30,000 of our outermost skin cells die so that we can live. When they do, new cells migrate from the inner layer of the skin to the surface of it, where they form a tough protective barrier. In a series of elegant experiments in mice, researchers at Rockefeller University have now discovered a tiny RNA molecule that helps create this barrier. The results not only yield new insight into how skin first evolved, but also suggest how healthy cells can turn cancerous. ...> Full Article

New Control Mechanism For Genetic Code Translation Discovered In Bacteria (2/17/2008)

Almost all organisms, from bacteria to human beings, share the same genetic code, a group of universal instructions used to convert DNA or RNA sequences into proteins, the "building blocks" of life. Identification of the evolutionary differences between the system for the translation of the genetic code in humans and other organisms, such as bacteria in this case, are useful, for example, for the design of new antibiotics. ...> Full Article

Killers in the kitchen: DNA helps track down foodborne disease (2/15/2008)

A rash of recent headlines hits close to home: Salmonella in peanut butter. E. coli in spinach and ground beef. In the United States alone, foodborne illnesses cause hundreds of thousands of hospitalizations and 5,000 deaths a year. ...> Full Article

Bacterium sequenced makes rare form of chlorophyll (2/9/2008)

Researchers have sequenced the genome of a rare bacterium that harvests light energy by making an even rarer form of chlorophyll, chlorophyll d. Chlorophyll d absorbs "red edge," near infrared, long wave length light that is invisible to the naked eye. ...> Full Article
