University of Georgia professor Richard Hussey has spent 20 years studying a worm-shaped parasite too small to see without a microscope. His discovery is vastly bigger. Hussey and his research team have found a way to halt the damage caused by one of the world's most destructive groups of plant pathogens.

Thanks to the many blood-safety interventions introduced since 1984, the overall risk for most transfusion-transmitted infections has become exceedingly small.

Parasitic flies introduced to control red imported fire ants have spread over four million acres in central and southeast Texas since the flies' introduction in 1999, researchers at The University of Texas at Austin have discovered using new flytraps they developed.

A Howard Hughes Medical Institute (HHMI) international research scholar in Israel has discovered one reason why so-called "flesh-eating" bacteria are so hard to stop.

Researchers have found for the first time that tarantulas can produce silk from their feet as well as their spinnerets, a discovery with profound implications for why spiders began to spin silk in the first place.

The phrase "easy on the eyes" may hit closer to the mark than we suspected.

A newly published study by investigators at the Center for AIDS Research at Case Medical Center, led by Benigno Rodríguez, MD, along with a nationwide team of AIDS/HIV experts, strongly challenges conventional thinking about the role of measurements of the amount of HIV particles in the blood as a method of predicting a patient's ability to fight off the disease. The study, published in the current issue of JAMA (Journal of the American Medical Association), indicates that the amount of HIV in a patient's blood (commonly known as the viral load) is much less reliable as a tool for determining the rate at which he or she will lose infection-fighting CD4 cells than previously thought.

Men who paint for a living may be placing their unborn children at increased risk of birth defects and low birth weight.
