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
Google Knol is a website similar in idea to wikipedia in which it encourages experts to "share what they know and a write a knol." What's a knol? Well it's a unit of knowledge, of course! (Disclaimer: I had to look it up myself).
What's interesting is that the Public Library of Science is now... Read More
Here's one for backyard grill-meisters and food safety experts:
Recently the American Chemical Society, as part of its semiannual meeting, staged a chemistry-themed barbecue reception on August 17 for reporters and other guests. (Great idea for getting press coverage, BTW)
"Cooking is as ... Read More
In a sign of heightened concern that the upcoming flu season could be severe, top national and local health officials warned Wednesday that employers should brace for worker absences and cautioned the public that as many as three shots this season may be needed to protect against the H1N1 strain...

In this article in the Huffington Post, Dr. Larry Dossey revisits the link between exposure to the microbes in dirt and self-reported happiness. 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

Immunology researchers at UT Southwestern Medical Center have found that bacteria present in the human gut help initiate the body's defense mechanisms against Toxoplasma gondii, the parasite responsible for toxoplasmosis.
Toxoplasmosis is generally a mild infection, but it can have serious an... Read More
It's not necessarily microbiology, but the fungus gnat does feed on algae and can be controlled in the garden with Bacillus thuringiensis, the bacterium that makes Mosquito Dunks effective.
Nevertheless it's a cool video. What I would like to know, and can't seem to find with a Google search,... Read More
In a presentation to the American Chemical Society meeting, Ankit Agarwal, a postdoctoral researcher at the University of Wisconsin-Madison, described an experimental approach to wound healing that could take advantage of silver's anti-bacterial properties, while sidestepping the damage silver c...

ABRCMS is the largest, professional conference for biomedical and behavioral students attracting approximately 2,900 individuals, including 1,800 students and 1,100 faculty and administrators. The conference is designed to encourage students to pursue advanced training in the biomedical and beha... Read More
According to a new report by Dr. Carlos Grijalva of Vanderbilt University, fewer US patients are receiving inappropriate antibiotics for coughs, colds, and other illnesses that do not benefit from antibiotic treatment.
Writing in the Journal of the American Medical Association, Dr. Grijalva ... Read More
A specific protein on the surface of a common bacterial pathogen allows the bacteria to leave the bloodstream and enter the brain, initiating the deadly infection known as meningitis. The new finding, which may guide development of improved vaccines to protect those most vulnerable, including yo... Read More
