In dark skies around the world there unfolds a nightly battle between bats and the nocturnal insects upon which they feast. You’d have thought bats, equipped as they are with echolocation — in which ...

The ability of bats to understand and use sound has always been essential to their survival. Though these winged creatures have eyes, they rely heavily on echolocation, which means that they use the ...

It’s not easy being deaf in the dark—especially when your greatest enemy is a master of sound. Such is the twilight plight of the humble cabbage tree emperor moth (Bunaea alcinoe): It’s all these ...

Dolphins do it. Big brown bats do it. And sometime soon, the Office of Naval Research hopes its researchers will be able to do it too. Echolocation, that is, and turning the processing of such signals ...

The Bat-Bot, developed by IST project CIRCE, can also wriggle its ears, a technique often used by bats to modulate the characteristics of the echo. CIRCE developed the Bat-Bot to closely mimic the ...

Scientists have known for years that bats navigate by sonar. Like destroyers hunting down a submarine, they send out pulses of sound and steer by the echoes that bounce back from obstacles or prey. In ...

Bioengineers have developed a new class of bionic 3D camera systems that can mimic flies' multiview vision and bats' natural sonar sensing, resulting in multidimensional imaging with extraordinary ...

Using sound to hunt for food is a pretty ingenious adaptation for bats flying at night. But it doesn’t work if another bat is messing with you. Scientists have discovered that a species of bats can ...
