Bear or chipmunk? Engineer finds how brain encodes sounds

When you are out in the woods and hear a cracking sound, your brain needs to process quickly whether the sound is coming from, say, a bear or a chipmunk. In new research published in PLoS Biology, a biomedical engineer at Washington University in St. Louis has a new interpretation for an old observation, debunking an established theory in the process.

Two drugs protect hearing better than one

Whether on a battlefield, in a factory or at a rock concert, noise-induced hearing loss is one of the most common hazards people face. Jianxin Bao, PhD, and other researchers at Washington University School of Medicine in St. Louis have identified a low-dose, two-drug cocktail that reduces hearing loss in mice when given before they are exposed to loud noise.
