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
The incidence of tuberculosis infections in the United States dropped by an unusual and unexpectedly large 11.4% in 2009, the largest one-year decrease since federal agencies began tracking the disease in 1953, the Centers for Disease Control and Prevention reported Thursday in its Morbidity and...

When a bacterium goes over the top with making a particular gene transcript, it needs a way to degrade that mRNA before it invests too much energy and resources in creating unneeded proteins. A new Observation piece accepted for the inaugural issue of mBio reveals that antisense RNAs may be an ... Read More
A team of scientists based at San Diego State University, the University of Chicago, and the University of South Florida have analyzed all sequence data available in public databases from complete genomes and environmental community genomes, and found out that jumping genes (known as transposase...

Duke Univ. researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology.
They are exploring whether their glassification technique could bring about protein-based drugs that are cheaper to make and ... Read More
It’s wondrous how the vast and the infinitesimal combine to make our planet work. Scientists at Woods Hole Oceanographic Institution (WHOI) have found that bacteria in the ocean, gathering in sort of “microbial block parties,” communicate and cooperate with each other to have a significant impac...

Perhaps Jerry Lee Lewis's rock n' roll classic will soon be topping the charts of virologists world wide! Read More
Talk about green jobs! The California company Microvi Biotech has developed a low cost, low impact, energy efficient system that puts billions of microorganisms to work, cleaning up notorious soil and groundwater pollutants like perchlorate, a rocket fuel additive that is also used to make expl...

Agricultural researchers at the Hebrew University of Jerusalem are developing an improved method for sustainable pest control using "super-sexed" but sterile male insects to copulate with female ones.
The scientists thus hope to offer yet another efficient and promising avenue for supplying ... Read More
Researchers have come up with a new way of sterilising medical equipment - by using a microwave.
Low-cost technology to kill harmful bacteria has been developed at Glyndŵr University in Wrexham.
Researchers found that by attaching a vacuum vessel to a microwave oven, atomic oxygen and ozon... Read More
As the first influenza pandemic of this century appears to have turned a corner, preparations are already under way for next flu season.
Today the World Health Organization picked the strains to go in next fall's Northern Hemisphere flu vaccine. The ingredients: the pandemic H1N1, or swine fl... Read More
A study has investigated whether a commercial real-time polymerase chain reaction test for MRSA could be used as a point of care test.
GeneXpert systems, used to carry out the MRSA test, were installed on four wards at the Sandwell and West Birmingham Hospitals NHS Trust and in the microbiolo... Read More
As if another reason was needed to quit smoking, though this one is certainly a doozy. Read More
The Haydel-Summers collaborative has added clarity to these distinctly muddy waters by screening more than 50 mineral mixtures (and aqueous extractions from them, known as leachates) marketed as health and cosmetic products using pathogens Escherichia coli, Salmonella enterica serovar Typhimuriu...

Swabbing down trauma patients with disposable, antiseptic-laced cloths appears to pay off in terms of infection control.
Doctors at Harborview Medical Center in Seattle found that patients given a daily antiseptic wipe down were much less likely to develop a catheter-related bloodstream infe... 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.
When the intestinal bacterium E. coli and the diarrheal pathogen ... Read More
Five states reported regional H1N1 influenza activity, and Puerto Rico and six states reported local influenza activity, U.S. health officials said Friday.
The weekly flu surveillance report -- completed during flu season by the Centers for Disease Control and Prevention -- said for the week ... Read More
