After 17 years underground, cicadas will return by the millions this summer. Here, an expert breaks down their life cycle and why they emerge when they do.

A tiny sensor chip smaller than a ladybug detects vibrations from sounds inside the body. It could warn of heart failure or lung problems.

Male treefrogs throw off predators teaming up with others to sing out their mating calls in quick succession, researchers say.

Researchers have shown light and sound could replace radiation to image the heart. They say the method has potential for other procedures as well.

Materials made from tapered chains of spherical beads could help dampen high-pitched sounds, say theoretical physicists.

Sensory danger zones, where light, noise, and chemical pollution overlap with animal habitats, put animals at serious risk, researchers say.

Throat singing produces two tones at the same time—a low rumble and a high whistle-like tone. Now researchers know how it works.

Surfing attacks use ultrasonic waves to control your phone from afar. They could let hackers make calls or read texts, all without you knowing.

Researchers have used 100 recordings of a cappella singing to better understand why the brain decodes music and speech in separate hemispheres.

Using a hearing aid could help people ward off cognitive decline or even help them improve their thinking, researchers find.
