Bat-killing fungus is a European import
Tracing the origins of the strain that causes white-nose syndrome in U.S. animals to Europe, scientists show that infection ups arousal rate during hibernation, depleting energy stores.

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. But the sharp jump in the cumulative death toll isn’t the only disturbing new development. 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.

Yet another study links insecticide to bee losses
Since 2006, honeybee populations across North America have been hammered by catastrophic losses. Although this pandemic has a name — colony collapse disorder, or CCD — its cause has remained open to speculation. New experiments now strengthen the case for pesticide poisoning as a likely contributor.
