Bat killer is still spreading
Since 2006, some 6 million to 7 million North American bats have succumbed to white-nose syndrome, a virulent fungal disease. That figure, issued in January by the U.S. Fish & Wildlife Service, at least sextupled the former estimate that biologists had been touting.

On April 2, scientists confirmed that white-nose fungus has apparently struck bats hibernating in two small Missouri caves. The first signs of clinical disease have also just emerged in Europe.
