HIV infects women by weakening a cell barrier in the reproductive tract that normally keeps viruses out, Canadian researchers have discovered. HIV breaks down the tight bonds between epithelial cells, which usually form a protective layer that prevents viruses from infecting other cells.

Massachusetts Institute of Technology (MIT) researchers have found a novel way to mimic the process by which plants use sunlight to split water into hydrogen and oxygen. They used a modified virus as a "biological scaffold" that can assemble the nanoscale components needed to split a water molec... Read More
Agricultural Research Service (ARS) scientists are figuring out how to turn wheat straw into ethanol "gold," and learning more about the bacteria that can "infect" ethanol plants and interfere with fuel production.
At the ARS National Center for Agricultural Utilization Research (NCAUR) in Pe... Read More
An experimental vaccine could be the newest weapon against a dangerous bacterial infection on the rise in hospitals and nursing homes around the United States.
Doctors at the University of Cincinnati and University Hospital are part of a national clinical trial testing a C. difficile - or C. ... Read More
In regard to your question as to cases of known alteration of host behavior by virus that increases the rate of contact among hosts (Twiv 70), the most dramatic example is given by rabies. This extraordinary virus can convert a neurologically and behaviorally... Read More
On episode #77 of the podcast This Week in Virology, Vincent, Alan, and Rich revisit circovirus contamination of Rotarix, then discuss poxvirus-like replication of mimivirus in the cell cytoplasm, a... Read More
The contamination of the rotavirus vaccine Rotarix with porcine circovirus 1 DNA was revealed by deep sequencing. The same technique was also used to demonstrate that oral poliovirus vaccine does not contain viruses that can cause poliomyelitis. Read More
A brewing trick could enable cask ales, unfiltered and unpasteurized beer, to be served on trains, aircraft and cruise ships. While ale normally takes two days to settle after each jolt, British brewer Marston's has developed a cask beer that can be poured a minute after the barrel has been move... Read More
Patients with chronic genotype 1 hepatitis C fared better when given an investigational drug developed by Johnson & Johnson division Tibotec and Vertex Pharmaceuticals than when given the standard therapy, after they had failed previous treatments, according to results of a mid-stage trial publi...

The U.S. Department of Agriculture recommends not washing raw poultry, beef, pork, lamb, or veal before cooking it. Chicken, too.
Bacteria in raw meat and poultry juices can be spread to other foods, utensils, and surfaces, the USDA says in its fact sheet "Washing Food: Do... Read More
Scientists are learning how our immune system senses and tracks down infection in the body by responding to chemical "scents" emitted by bacteria. Studying how immune cells manipulate their movement in response to external signals could shed light not only on how our immune system functions but ... Read More
Researchers are finding clever ways to explore nanotechnology for medical therapies. In a study published Thursday in the journal Immunity, researchers used a "nanovaccine" to reverse diabetes in mice with the disease.
Nanoparticles are spheres that are thousands of times smaller than any typ... Read More
