When temperatures get colder and the days get shorter, many mammals settle into a period of hibernation. But what effect will climate change — and the associated changes in weather patterns — have on this annual behavior? [Read more…]

In 2008, scientists at the National Institute of Deafness and Other Communication Disorders identified that those who stuttered often had a mutation in the gene Gnptab. The discovery was particularly interesting, because, previously, the gene had only been believed to be related to “general housekeeping” of the body, such as digestion. How could a gene that affects every cell of the body cause something so mechanical as stuttering? [Read more…]
