Researchers at Ohio State University have pinpointed a human gene product that helps to regulate wound healing and may control scarring in people recovering from severe injuries and damage to...

A variant in the gene IRF4 has been linked to hair graying in humans - a discovery that researchers say could lead to strategies that prevent or reverse hair graying.

MicroRNA can serve as a "decoder ring" for understanding complex biological processes, a team of New York University chemists has found.

Young animals recover from tissue damage better than adults, and from Charles Darwin's time until now, scientists have puzzled over why this is the case. A study published by Cell Press in the journal Cell has revealed that an evolutionarily conserved gene called Lin28a, which is very active in embryos but not in adults, enhances tissue repair after injury when reactivated in adult mice.

Why some people are troubled by cold sores while others are not has finally been explained by scientists. Cold sores affect around one in five people but, until now, no one has been sure why some are more prone to the virus that causes them...

In new findings published in the New England Journal of Medicine (Epub ahead of print), researchers from the Kennedy Krieger Institute reveal the discovery of the cause - a genetic mutation that occurs before birth - of Sturge-Weber syndrome (SWS) and port-wine stain birthmarks...
