The results of a new study suggest that bacteria that cause diseases like bubonic plague and serious gastric illness can turn the genes that make them infectious on or off. Knowing how disease-…

Up to 15 percent of couples of childbearing age struggle with the heartache of infertility. Now there is the promise of new hope with Cornell researchers' identification of a mutation in a gene that…

University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were…

Starting to breed late in life is a bad idea if you want to maximise the number of offspring that you produce - or so the theory goes. But doubt has now been cast on this hypothesis - one of the…

Given the choice, many of us would opt for warmer climes during the bleak midwinter. However, most of us cannot afford to move abroad for a few months, so instead we pile on extra layers of clothing…

Tree frogs have the unique ability to stick to smooth surfaces even when they are tilted well beyond the vertical - some small tree frogs can even adhere when completely upside down. Conversely when…

The ribosome is the protein-producing nanomachine in cells that keeps the human body cranking along. A discovery by University of Maryland researchers has provided a clue that could lead to…

Researchers at Purdue University and The Catholic University of America have discovered the structure of an enzyme essential for the operation of "molecular motors" that package DNA into the head…

Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign…

Researchers have identified a novel gene mutation that causes X-linked mental retardation for which there was no previously known molecular diagnosis, according to an article to be published…
