Pandemic flu activity remained at uncharacteristically low levels for week 10 of the season, the US Centers for Disease Control and Prevention (CDC) said in its most recent update, though the virus is still circulating amid anecdotal reports of increased activity in a few southern locations.

A new generation of drug-resistant bacteria could be coming faster, and through a different mechanism, than researchers had expected.
That is the scary finding of a new study by William Fairfield Warren Distinguished Professor James J. Collins, a College of Engineering professor of biomedical... Read More
Rival colonies of bacteria can produce a lethal chemical that keeps competitors at bay, scientists at UC San Diego, University of Texas and Tel Aviv University report this week.
By halting the growth of nearby colonies and even killing some of the cells, groups of bacteria preserve scarce r... Read More
RNA Isolation from soil is one of the most difficult applications we perform in environmental molecular biology. RNA purification is always an arduous task and from soil it becomes a bigger challenge. One of the biggest problems is the yield of RNA from soil. Because typical yields of RNA are s... Read More
The American Society for Microbiology (ASM) will hold its 110th General Meeting May 23-27, 2010 in San Diego, California. The meeting will feature approximately 3,000 individual scientific presentations spanning the breadth of microbiology and has an expected attendance of 10,000.

The US Food and Drug Administration has recommended that administration of the Rotarix vaccine, which protects against rotavirus infection, be suspended. This action comes after an independent research group found that the vaccine contains DNA of porcine circovirus type 1. Read More
Vincent Racaniello, host of This Week in Virology, appears in the latest episode of Futures in Biotech with Marc Pelletier.
With a focus on RNA viruses, Vincent and and Marc are joined by Stanford University School of Medicine Professor Karla Kirkegaard and discuss where RNA viruses came from... Read More
Scientists are pioneering a way of discovering new antibiotics by analysing the entire genetic blueprint of soil microbes which kill their competitors by producing natural toxins. Screening soil microbes for novel antibiotics is a traditional method of discovering new drugs but the rise of resis... Read More
The peptide beta amyloid has long been thought to be involved in Alzheimer's disease, though there is a great deal of controversy about whether it's a primary cause of the disease, or merely a symptom. Now, Rudolph Tanzi and his group at Massachusetts General Hospital have shown it might not be ... Read More
A group of French hospitals has reduced the burden of MRSA (methicillin resistant Staphylococcus aureus) among patients by more than a third after a 15-year-long multi-prong control program, according to a new report published online March 22 in the Archives of Internal Medicine.
The 38 teach... Read More
The National Institutes of Health will use its Small Research Grant program to fund science into rare immunodeficiency diseases, including studies focused on molecular knowledge, biomarkers, and diagnostic technologies.
Funded by the National Institute of Allergy and Infectious Diseases and t... Read More
Drug-resistant tuberculosis killed about 150,000 people in 2008, and half of all the world’s cases are thought in be in China and India, the World Health Organization said in a report last week.
No one knows the exact number of cases of the two types of drug-resistant TB, called MDR and XDR f... Read More
Scanning electron microscopy photograph of a human isolate of Naegleria fowleri amoeba grown in axenic culture displaying sucker-like structures, called amoebastome, used for a novel form of phagocytosis. There appears to be an inverse correlation between the mean number of suckers per amoeba an... Read More
Merry Youle of the Small Things Considered blog has a new post up that looks at the phage-encoded holin timer and its function in a lytic infection.
"Holins are the smallest known biological timers. Timers, not clocks. Timers tick along, then go off after the specified interval. These small, ... Read More

The Food and Drug Administration on Monday warned doctors and parents against using the Rotarix rotavirus vaccine until further testing can confirm that it is safe. The warning follows the discovery by an academic research group--subsequently confirmed by the FDA and Rotarix manufacturer GlaxoSm... Read More
Scientists have unveiled a new natural sourdough ingredient that could replace conventional additives in a variety of other breads, while making them tastier and more healthful.
They described their achievements at the American Chemical Society's 239th National Meeting, being held in San Fran... Read More
Scientists have discovered two novel ways of killing the bacteria that cause tuberculosis (TB).
According to researchers at Albert Einstein College of Medicine of Yeshiva University, their findings could lead to a potent TB therapy that would also prevent resistant TB strains from developing... Read More
