Although wind turbines may be a valuable source of eco-friendly energy, they do have at least one drawback – bats are frequently killed by their spinning blades. A promising new system is designed to ...

It might not be able to monitor an entire city, but Steve Hoefer’s brilliant sonar glove will at least let you get to the bathroom at night without stubbing your toe, thanks to an ultrasonic emitter ...

Bats use a clever technique called echolocation to hunt down food in the dark, mapping their surroundings by emitting ultrasound waves from their mouths and analyzing those that bounce back.

"Lots of things fly at night," says Harlan Gough, a wildlife biologist with the U.S. Fish and Wildlife Service. Nightfall can set the stage for an acrobatic high-stakes drama in the air — a swirl of ...

Although bats are nocturnal, they’re hardly flying blind. Most bats see with sound thanks to echolocation: They emit ultrasonic calls that bounce back off physical objects in front of them.

Researchers at the University of Michigan have developed an AI-powered echolocation system that allows robots and drones to navigate in total darkness. No cameras, GPS, or laser sensors needed.

For many nocturnal moths, hearing sound waves is a matter of survival in the night sky. Their ability to detect ultrasonic calls emitted by bats determines whether they escape or become prey. This ...

Researchers played simulated bat echolocation calls in the laboratory and found that egg-bearing A. nigrisigna stopped flying when exposed to high pulse repetition rates. This behavior could be ...
