Why Young Are Most Affected by Swine Flu Revealed in Virus Structure

A team of scientists from The Scripps Research Institute and other institutions has solved the structure of a key protein from the virus that caused last year's "swine flu" influenza epidemic. The structure reveals that the virus shares many features with influenza viruses common in the early 20... Read More

Do Low-Level Antibiotics Create Mutant “Zoos”?

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

Colonies of Bacteria Fight for Resources with Lethal Protein

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

10 Tips for the Isolation of High Quality RNA from Soil

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

Porcine circovirus DNA in rotavirus vaccine

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

Futures in Biotech 56: RNA viruses and more

Vincent Racaniello, host of This Week in Virology, appears in the latest episode of Futures in Biotech with Marc Pelletier.

Fight against superbugs goes underground

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

Microbes implicated in Alzheimer's

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

French hospitals make progress in battle against MRSA through large-scale prevention and monitoring

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.

Tuberculosis: Drug-Resistant Strains Still Spreading at Deadly Rates, W.H.O. Report Says

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

Sucker-Like Structures on the Pathogenic Amoeba Naegleria fowleri

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

Time's Up

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
