Sleep remains one of the big mysteries in biology. All animals sleep, and people who are deprived of sleep suffer physically, emotionally and intellectually. But nobody knows how sleep restores the…

Scientists at the Salk Institute for Biological Studies have identified an enzyme that pumps up a cell’s ability to maintain healthy muscle and restores normal muscle function in genetically…

Dr. Yijun Qi (National Institute of Biological Sciences, China), reports his discovery of microRNAs in the unicellular green alga, Chlamydomonas reinhardtii. This is the first finding of microRNAs in…

Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. These reservists normally lie around and do…

Brains are able to adjust automatically to the demands of distinguishing between small differences in smell, new research at the University of Chicago shows. The research, which was conducted on…

Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine—a future where advanced organ damage can be repaired by the…

Oregon Health & Science University neuroscientists are eyeing a protein as a potential therapeutic target for multiple sclerosis because de-activating it protects nerve fibers from damage. OHSU…

Marvin Chun of Yale University and colleagues have pinpointed brain regions critical to one of the brain’s more remarkable feats — piecing together a continuous view of the world by integrating…

Cells constantly swap cargo bound in vesicles, miniscule membrane-enclosed packages of proteins and other chemicals. Before the swap can take place, the vesicle membrane must fuse with another…

Researchers have discovered how a defect in a single master gene disrupts the process by which several genes interact to create myelin, a fatty coating that covers nerve cells and increases the…
