A new study reports that a vaccine-induced cellular immune response reduced simian immunodeficiency virus (SIV) levels in the semen of rhesus monkeys during the period of primary infection, a discovery that may ultimately aid in the fight against HIV-1 transmission in humans. The researchers fro... Read More
Some people eat to avoid being bored. Others to avoid doing something they’d rather not, like preparing a podcast. Now a report says we might eat to avoid fungi. Because warm-bloodedness, a condition that requires a lot of calories, may have evolved to keep fungal infections at bay.

Creating an original organism required no bolt of lightning for a team of University of Virginia students. But it did take buckets of ice, vials of bacteria and a FedEx delivery.
Nestled in the package were bits of DNA, whipped up in California and ordered online. When they arrived at a lab c... Read More
About 1 in 5 U.S. children had a flu-like illness earlier this month — and most of those cases likely were swine flu, according to a new government health survey. About 7 percent of surveyed adults said they'd had a flu-like illness, the survey found.
The information comes from a household su... Read More
Scientists who study RNA have faced a formidable roadblock: trying to examine RNA's movements in a living cell when they can't see the RNA. Now, a new technology has given scientists the first look ever at RNA in a live bacteria cell -- a sight that could offer new information about how the mole... Read More
Streptococcus agalactiae (also called Group B Streptococcus, or GBS) is a versatile pathogen that affects a variety of animals. Now studies by Agricultural Research Service (ARS) scientists and their university colleagues are revealing new information about this pathogen.
