A man-made bat cave in Tennessee is looking for tenants. An hour northwest of Nashville, the artificial cave is built to give thousands of bats a haven from a devastating infection called white-nose syndrome.
Millions of bats in the Northeast have died from the infection since it first showed up a few years ago. The culprit is an invasive fungus that grows in caves. When bats hibernate inside, they wake up with faces covered in white fuzz and often wind up starving or freezing to death.
