For the last year and a half, sea stars all along North America's Pacific coast - from Baja California all the way to Alaska - have been withering away into nothingness. Today, researchers announced they've found the culprit: it's a virus. » 11/17/14 4:20pm 11/17/14 4:20pm

Why Scientists Need Surfers to Study the Ocean

Earth's oceans remain largely unexplored. But some of the most difficult waters to study aren't in the middle of nowhere, but just off shore, where crashing waves can make data collection dangerous. Engineer Benjamin Thompson thinks he has a solution: water-monitoring surfboard fins. » 11/05/14 1:40pm 11/05/14 1:40pm

The Art on These Endangered Species Stamps Is Incredible

Since 1993, the United Nations has worked to increase global awareness of endangered species through a special set of commemorative postal stamps released each year.
