Bats are masters of echolocation, a skill that allows them to identify objects around them using sound. But not every bat species tunes into this superpower the same way. Scientists are just ...

A bat vibrating at its fundamental frequency (above, in black) has a node of zero vibration about 6 1/2 in. from the barrel end (Node 1). This was long thought to be the bat's sweet spot.

Analysis of bats’ inner ear anatomy supports a previously proposed arrangement that was based on DNA analysis. The findings also shed light on the evolution of echolocation.
