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
In this show, I report on four exciting stories: a plant-fungus symbiosis, making algae make medicine, fighting cancer with a virus, and making biofuels out of wood scraps.

As researchers, sneakers on, trickled out of UC San Francisco’s Genentech Hall on a warm, windless evening this week, assorted persons with stylish glasses and prettier footwear made their way against the flow and into the building’s marble atrium.
The California College of the Arts and the ... 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.
That's the idea behind a study to observe a specific bacteria that infects tomatoes but normally does not bother the... Read More
Researchers have devised a way to attach sugars to proteins using unique biological and chemical methods. This means that large quantities of different glycoproteins can be generated for various medical and biological studies.
The E. coli bacterium produces a protein to which a sugar is attac... Read More
A virus first discovered in primates living in the Tana River Valley in Kenya is being tested by a London company as a treatment for rheumatoid arthritis.
Viron Therapeutics is reporting that in tests with mice, VT-346 -- derived from the Tanapox virus -- has been up to 100 times more potent ... Read More
For two decades, scientists have been pursuing a potential new way to treat bacterial infections, using naturally occurring proteins known as antimicrobial peptides (AMPs). Now, MIT scientists have recorded the first microscopic images showing the deadly effects of AMPs, most of which kill by po... Read More
Alternative approaches to medicine are stock-in-trade in the ASU laboratory of microbiologist Shelley Haydel.
So when ASU senior Jenny Koehl joined Haydel's investigative team seeking firsthand knowledge of how basic research is done, how drugs are tested and potential cures produced, she fou... Read More
A cheap acne drug that's been used for decades appears to target infected immune-system cells in which HIV lies dormant before coming back to life and spreading infection, researchers have found.
The authors of a new study say the antibiotic drug, minocycline, sold under names such as Minocin... Read More
Really though, even Yakov Smirnoff would be worried about this one - bacteria put Big Pharma's R&D to shame, evolving resistances much faster than we develop new antibiotics. Read More
Last year a mutation in the HA gene of the 2009 H1N1 influenza virus was identified in isolates from patients with severe disease. At the time I concluded that the emergence of this change was not a concern. Recently the Norwegian Institute of Public Health reported that the mutation, which caus... Read More
Kathy Hudson has been worrying about the quality of genetic tests for years, and now—after becoming chief of staff to National Institutes of Health Director Francis Collins—she's doing something about it.
More than 1600 genetic tests are on the market, and there aren't enough regulations to e... Read More
An estimated 440,000 people had multi-drug resistant tuberculosis in 2008 and a third of them died as the new variant of the TB mycobacterium continues to spread, the World Health Organization said Thursday. Nearly half of the cases were in China and India, which have been hit hardest by the out... Read More
It’s well established that critical human body functions, including sleep, hormone production and regulation of body temperature, follow a circadian (24-hour) cycle. These genetically programmed patterns stay in effect even under isolation from the naturally occurring daily light-dark cycles of ... Read More
