The recently emerged field of bacterial riboswitches may be a good hunting ground for effective targets against bacterial infection, according to a report by Yale researchers in the journal Chemistry and Biology.

University of North Carolina at Chapel Hill scientists have demonstrated in a living organism that cancers may cause surrounding supportive cells to evolve and ultimately promote cancer growth.

The same satellite system used by the U.S. military to track vehicle convoys in Iraq is helping World Wildlife Fund shed light on the little-known world of pygmy elephants in Borneo.

One of the most commonly prescribed drugs for breast cancer, tamoxifen, may not be as effective for women who inherit a common genetic variation, according to researchers at the University of Michigan and the Mayo Clinic.

Millions of poor rice farmers and consumers in Asia have received a little good news just in time for Christmas.

When threatened by predators, sea slugs defend themselves by ejecting a potent inky secretion into the water consisting of hydrogen peroxide, ammonia and several types of acids. A team of researchers with the Atlanta-based Center for Behavioral Neuroscience (CBN) has found that this secretion is produced from normally inert chemicals stored separately in two glands. The discovery, published in the Dec. 16 on-line edition of the Journal of Experimental Biology, provides insight into a natural chemical process with potential industrial applications.
