Little brown bat; close-up of nose with fungus.

No one is sure exactly how white-nose syndrome works or where it came from, but apparently the "white nose" results from a fungus that infects the bats while they hibernate. Researchers are trying to figure out how white-nose syndrome spreads, why it kills the bats, and how it can be prevented before bats become entirely extinct.
Not a bat fan? Consider this: Bats eat about 600 insects a night. (And you thought your potato-chip binge was bad!) That means the fewer bats there are, the more bugs. And that's sure to bug even the biggest bat-hater.
