Ira Flatow of Science Friday will host a panel discussion on the issues surrounding a federal advisory board that has urged scientific journals not to publish the research from two labs that have developed an airborne bird flu virus (H5N1). Virologist Vincent Racaniello and Biosecurity expert D.... Read More
The controversial Andrew Wakefield, MBBS, whose now largely discredited research ignited the vaccine-autism furor, has filed a defamation suit in a Texas court against BMJ, its editor, and an investigative journalist over a series of articles published last January.
The articles, by Brian Dee... Read More
For years, medical professionals and the livestock industry have made great efforts not to overuse antibiotics, but drug-resistant microorganisms continue to thrive.
Hua Wang thinks she knows why: Antibiotic usage is just one of the factors causing resistance, she said.
"Antibiotic resista... Read More
The FDA is sending mixed signals: It unveiled new limits this week on one class of livestock antibiotics, two weeks after scrapping a 34-year push to limit two others. All three can promote drug-resistant bacteria, aka superbugs.
If you didn't keep up with the Federal Register over the holida... Read More
U.S. Early Career Scientists: Submit your application by January 10 for the opportunity to collaborate with Australian colleagues!
Managed jointly by the ASM and the Australian Society for Microbiology, the Millis-Colwell Exchange Program for Early Career Scientists will provide a U.S. scient... Read More
Recent reports that two teams of scientists had genetically altered a deadly flu virus to make it more contagious have provoked fear, even outrage, in some quarters.
Biosecurity advisers to the American government, which paid for the research, have urged that full details not be published for... Read More
Of the top 10 most blogged articles in 2011 from the Chronicle of Higher Education, one article is on Johne’s disease, a contagious, chronic and sometimes fatal infection that primarily affects the small intestine of cows, sheep and other ruminants. It is caused by the bacterium Mycobacterium av... Read More
A team of scientists from Boston University School of Medicine (BUSM) have identified a novel compound that inhibits viruses from replicating. The findings, which are published online in the Journal of Virology, could lead to the development of highly targeted compounds to block the replication ... Read More
To eke out even the barest subsistence on Mars, a living thing would have to adapt to a formidable set of environmental challenges: an arid, often extremely cold landscape with miniscule amounts of oxygen in the atmosphere and no organic matter to eat. During a recent foray into a similarly inho... Read More
A bacteria-filled filter is being perfected to prevent bad industrial smells from spreading over a whole town.
A biofilter laden with bacteria is designed to stop bad industrial smells at the source.
The bacteria can eat most of the compounds that produce the worst odors.

An experimental herpes vaccine protected young women against only one of the two types of the sexually transmitted virus, dashing hopes for widespread use of the treatment, researchers reported in the latest issue of the New England Journal of Medicine.
For reasons that aren’t clear, the vacc... Read More
Tempting fate is never wise; tempting a flu pandemic is downright foolish. Yet it is impossible for scientists to understand influenza or create vaccines without at least some risk. The question, then, is what level of risk is acceptable.
On December 20th the American authorities said they ha... Read More
Should a study by a team of students from Missouri University of Science and Technology become reality, individuals suffering with diabetes will be able to monitor their blood sugar levels in a more cost-effective way.
Recently, the team of students at the Missouri S&T chapter of iGEM - the ... Read More
For centuries tansy has been used as a folk remedy, but now scientists from Britain and Spain believe the plant may have medical benefits after all, as a treatment for herpes. The team's findings, published in Phytotherapy Research, are the result of joint work between two teams to established s... Read More
Under a high magnification of 21930x, this scanning electron micrograph (SEM) depicted some of the ultrastructural morphologic features displayed by this group of Gram-positive Micrococcus luteus bacteria. The specimen was obtained from a pure culture that was raised on a polycarbonate filter, f... Read More
WE ARE now privy to the ways bacteria outsmart antibiotics, thanks to a technique which measures the evolution of antibiotic resistance.
A team led by Erdal Toprak and Adrian Veres at Harvard University developed the "morbidostat", a device that constantly monitors the growth of bacteria in t... Read More
For NASA’s Martian rovers, it seems that bigger is better. The $2.5 billion (£1.6 billion) Curiosity — which is currently whizzing towards the red planet following its November 2011 launch — is five times bigger than twin predecessors Spirit and Opportunity.
In fact it’s taller than most bas... Read More
Why is there such widespread fear of avian H5N1 influenza virus?
Why did Paul Keim, chair of the National Science Advisory Board for Biosecurity (NSABB) say “I can’t think of another pathogenic organism that is as scary as this one”. What lead Donald McNeil, writing about H5N1 in the New Yor... Read More

Virus-bacterium associations were examined in the natural environment of a termite's hindgut. Three general scenarios were seen. In the first (1) there was a one-to-one association: one type of virus matched one type of bacterium host. In the second (2) the host bacterium was associated wi... Read More
