...in the mountains. The rain has led to a heavy snow pack in the Sierra Nevada, which typically means a good year for butterflies in the high country. Snow protects the dormant insects from cold and drying. But the snow came late in the season, meaning that many of the overwintering insects may have been ki...Imbalance may trigger advance from fatty liver to liver failure

The Arctic ice pack is home to thousands of Pacific walrus. Their preferred habitat is an ice floe that has enough density and surface area to support a herd of 12-foot-long, 3,000 pound mammals. In the spring, walrus haul out on this floating ice to rest, mate and rear...Stanford discovery may help predict when toxoplasma can be deadly
