SHARE Coral Reef Bleaching In Hawaii; Dog Aging Project

Record-breaking temperatures in Hawaii this past summer may lead to unprecedented coral bleaching. It's caused by changes in water temperature, light or nutrients and it can kill coral. Scientists on an island in Oahu are taking underwater photos to create a one-of-a-kind, time-lapsed documentation of bleaching. And, the Dog Aging Project is seeking canine participants in what could be the largest study on aging ever conducted. The goal is to discover more about human aging by studying dogs, which share many of the same genetic markers with humans.
