New tenants wanted: must be quiet during the day, must enjoy bugs.

It might not sound like your kind of real estate, but the architects of a new manmade cave near Clarksville, Tennessee are hoping it will attract bats. The bats need a haven because they are threatened by a devastating and mysterious fungus that grows like white fuzz on their faces and wings as they hibernate. The fungal infection is called white-nose syndrome.
