Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat ...

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 ...

What do bats, dolphins, shrews, and whales have in common? Echolocation! Echolocation is the ability to use sound to navigate. Many animals, and even some humans, are able to use sounds in order to ...

Bats have been using sonar to navigate and communicate for ages, and now humans can do the same, thanks to lightweight and efficient ultrasound microphones and loudspeakers developed by physicists.

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 ...

In yet another first for graphene, physicists from the University of California, Berkeley, have employed this versatile material to create ultra-thin, lightweight ultrasonic microphones and speakers ...

“Ultrasonic,” Stuart Hyatt’s eighth recording as Field Works, turns their high-frequency sounds into haunting music. By Grayson Haver Currin On an unseasonably cool evening in late May, Stuart Hyatt ...
