Scientists had previously observed that some species of shrews undergo a form of biological plasticity in which their bodies, skulls, brains and some organs shrink in the winter, then regrow in the spring. Now, a new study ...
Between 29,000 and 19,000 years ago, the planet experienced some of its coldest temperatures and drastic landscape changes at the peak of the Ice Age, during the Last Glacial Maximum (LGM), the period of most extensive global ...
