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.

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
Researchers have looked deeper into the makeup of DNA to get clues about why people might have different colors of hair or eyes, why some are taller or heavier and why some are more susceptible to certain diseases.
They found that changes in chromatin structure and transcription factor bindin... Read More
The ability of microbes, tiny organisms that do big jobs in our environment, to go dormant not only can save them from death and possible extinction but may also play a key role in promoting biodiversity and ecosystem stability.
In a paper published this week in the Proceedings of National Ac... Read More

Researchers at CIRES at the University of Colorado Boulder Campus found a connection between the unique bacteria found on an individual's hand and the bacteria left on commonly used devices such as computer keyboards and mice. The study holds future promise for forensic uses. Listen to CU Resear... Read More
Countries producing food containing harmful bacteria and toxins could be named and shamed more quickly using a worldwide alert system devised by a team of scientists from Kingston University in South West London. The team, led by Professor Declan Naughton, says the easy to use computer tool can ... Read More
Understanding how plants defend themselves from bacterial infections may help researchers understand how people and other animals could be better protected from such pathogens.
