A new vaccine may be able to provide some protection against all strains of influenza.
Current immunizations create antibodies that target a specific piece of a molecule on the surface of the virus that researchers call its “head.” That piece of the hemaglutinin protein evolves very quickly... Read More
The last (and only) defense against the ongoing Deepwater Horizon oil spill in the Gulf of Mexico is tiny—billions of hydrocarbon-chewing microbes, such as Alcanivorax borkumensis. In fact, the primary motive for using the more than 830,000 gallons of chemical dispersants on the oil slick both a... Read More
Researchers report that germs living in your gut could affect your risk of developing colon cancer.
The findings suggest that signs of the existence of some germs "are more frequently detected in subjects with polyps, early lesions that can develop into cancer, while other bacterial signature... Read More
While reading my back issues of Applied and Environmental Microbiology (AEM), I came across an interesting paper that detailed an in-depth study on the effectiveness of hand cleaners to remove Norwalk virus (NV) from intentionally contaminated hands.
Yes that’s right – intentionally contamina... Read More
A closely watched experimental hepatitis C treatment being developed by Vertex Pharmaceuticals Inc led to a 75 percent cure rate in a pivotal late-stage trial of previously untreated patients, the company said on Tuesday.
The results from the first Phase III study of telaprevir were roughly i... Read More
I joined Marc Pelletier on episode 60 of Futures in Biotech for a conversation with Dave Brodbeck, George Farr, and Andre Nantel. We talked about primate face recognition, discovery of a new antiviral compound to treat hepatitis C virus infection, changing the length of a codon from three to fou... Read More
Now that the thimerosal-autism link has been thoroughly discredited, some autism advocates argue that neurodevelopmental problems are caused by overloading children's immune systems with too many vaccines too early in life. As a result, a growing number of parents are asking pediatricians to use... Read More
While Bones might be overestimating his skills there a mite bit, I think the simple "old country Doc" would see the potential for this therapy to move us more towards the sort of medicine he's accustomed to practicing. However, if he does work that rainy day cure out, I have need of him in subu... Read More
