The treatment is for bowel disorders such as inflammatory bowel disease, which affects one in 400 people in the UK and for which there is no cure. The bacterium Bacteroides ovatus acti... Read More
By studying the intricate mechanisms at work in protein production, a Princeton-led team has discovered why certain kinds of antibiotics are so effective. In doing so, they also have discovered how one protein protects against cell death, shedding light on a natural cancer-fighting process.

Genome-sequencing pioneer Craig Venter and his team have devised a way of smuggling an "alien" genome into unwitting bacterial cells. The new technique takes the scientists one step closer to their goal of creating novel microorganisms with entirely synthetic genomes.
So Craig Venter, the guy who helped map the human genome in the 1990s, has created a completely novel life form by smuggling and alien genome into an unsuspecting bacterium. Read More
New federal guidelines released today recommend actions that non-healthcare employers should take now to decrease the spread of seasonal flu and 2009 H1N1 flu in the workplace and to help maintain business continuity during the 2009–2010 flu season. Read More

Bacteria commonly found in soil, Mycobacterium vaccae, have proved to stimulate the same areas of the brain as common antidepressants, such as Prozac. Read More
Scientists have used a new vaccine production technology to develop a vaccine for norovirus, a dreaded cause of diarrhea and vomiting that may be the second most common viral infection in the United States after the flu. Sometimes called the "cruise ship virus," this microbe can spread like wild... Read More
Engineers at Ohio State University have found a way to double the production of the biofuel butanol, which might someday replace gasoline in automobiles.
The process improves on the conventional method for brewing butanol in a bacterial fermentation tank.
Normally, bacteria could only prod... Read More
