Scientists have discovered a signaling pathway that tuberculosis bacteria use to coerce disease-fighting cells to switch allegiance and work on their behalf. Epithelial cells line the airways and other surfaces to protect and defend the body. Tuberculosis bacteria co-opt these epithelial cells i... Read More

Suicide among AIDS patients in Switzerland dropped by more than 50 percent after they started getting antiretroviral drugs in 1996, a recent Swiss study has found.
Virtually all Swiss AIDS patients get the medicine they need, but the study may prove significant in the third world as well. Th... Read More
In the swimming motions of aerobic bacteria against asymmetric gears, apparent randomness can yield directed motion. The collective random motion of tiny bacteria can be harnessed to turn much larger mechanical gears in a preestablished direction, a new study demonstrates. The research, set to b... Read More
There is some evidence that viruses are involved in colony collapse disorder, a phenomenon in which worker bees disappear. This condition is receiving a great deal of attention ranging from basic scientific research (summarized on TWiV 46) to a PBS episode to a documentary entitled 'Colony' whic... Read More

A vital gene that defends us against cancer has been found in one of the simplest of animals – a flat, amoeba-like creature called a placozoan. The discovery shows that p53, sometimes described as the "guardian of the genome", has been around for over 1 billion years.
The Placozoa are among t... Read More
Athletes be warned: the way illegal doping is detected is on the cusp of a radical change.
