Scientists Probe Deaths of Thousands of Bats

Bats in New York and Vermont are mysteriously dying off by the thousands, often with a white ring of fungus around their noses, and scientists in hazmat suits are crawling into dank caves to find out why. "White nose syndrome" as the killer has been dubbed, is spreading at an alarming rate with researchers calling it the gravest threat in memory to bats in the U.S. You may ask yourself, why worry about bats. Bats feed on insects that can damage dozens of crops, including wheat and apples, so they are needed.
