A federal advisory committee yesterday recommended increased biosafety precautions for research involving H5N1 avian influenza viruses that can spread among mammals, a step that stems from the ongoing controversy over studies involving lab-modified H5N1 strains that show increased transmissibili...

Forget chicken soup or hot tea. There is a new batch of home flu remedies — and they don’t skimp on the alcohol.
When Jeni Britton Bauer, owner of Jeni’s Splendid Ice Creams in Columbus, Ohio, was young, getting a cold or the flu meant her mother and grandmother would mix up a cocktail of the... Read More
Although the flu appears to be leveling off in the East, South and Midwest, numbers are still rising in the Southwest and Northwest, the Centers for Disease Control and Prevention reported.
The flu is widespread now in Washington state, said Donn Moyer of the Washington State Department of He... Read More
This episode: Figuring out which bacteria help fecal transplants work so well against C. difficile!
Vanderbilt biochemists have discovered that the process bacteria undergo when they become drug resistant can act as a powerful tool for drug discovery.
Their findings -- reported this week in the Online Early Edition of the Proceedings of the National Academy of Sciences -- should give a majo... Read More
If we are to believe a half-century of daytime TV commercials, housekeeping is war — a perpetual battle against the sneaky soldiers of nature. For decades, we’ve armed ourselves with cleaning products to slay bacteria, scrape away fungus and torture mites. As our household organisms move up the ... Read More
Some carbon nanotubes used for strengthening plastics may have an adverse effect on soil microbiology.
Specifically, these raw, non-functionalized single-walled carbon nanotubes were shown to damage the active microbes in low-organic soil.
Ron Turco, a professor of agronomy at Purdue Unive... Read More
A new study could provide the link that scientists have been looking for to confirm that reactivation of a latent herpes virus is a cause of some heart problems.
Looking at blood samples from 299 heart patients, researchers at Ohio State University found that those who had suffered a heart at... Read More
At least 20% of people, including half of schoolchildren, were infected with swine flu during the first year of the pandemic in 2009, according to data from 19 countries.
It is thought the virus killed 200,000 people around the world.
A World Health Organization-led study looked for eviden... Read More
Business Week interview with a fashion designer who makes her collection from bacteria:
This is really in its infancy, no?
I’m still very much focusing on apparel and luxury products—jewelry, things that use small amounts of material. The lab materials are quite expensive and are not being p... Read More
Researchers at the Paris Cardiovascular Research Center (PARCC) have shown how adhesion of Neisseria (N.) meningitidis to human microvessels in a humanized mouse model leads to the characteristic cutaneous lesions of meningococcal sepsis. This work, published on January 24 in the Open Access jou... Read More
Professors, you've discussed this idea before, but I thought you'd enjoy this nice summary from Nature:
Every minute of its existence, a living cell must assess and analyze myriad bits of information—everything from the temperature of its environment to the chemical makeup of its surroundings. Sometimes, these inputs cause a cell to change how it functions, but other times, the information may not... Read More
Researchers from computer firm IBM say they have invented a new non-toxic gel that can kill deadly drug-resistant bacteria by cutting through the sludge that shelters them and attacking the germ's cell membrane.
If verified, the finding could herald a breakthrough in the fight against the sup... Read More
The alarm system the helps immune system cells destroy invading bacteria points to a potentially new way to protect people from biological weapons, researchers report.
Cells in the immune system called macrophages normally engulf and kill intruding bacteria, holding them inside a membrane-bou... Read More
The highest rates of infection were in children, with 47 per cent of those aged five to 19 showing signs of having caught the virus. Older people were affected less, with only 11 per cent of people aged 65 or older becoming infected.
The findings come from an international collaboration led b... Read More
The polio virus has been found in the sewers of Cairo, and it appears to have come from Pakistan, the World Health Organization said Wednesday. Egypt has not had a case of polio since 2004. A vaccination drive is being planned for Feb. 25, and health workers are canvassing the neighborhoods wher... Read More
