A person prepares to hit a squash ball with a racket.

No player can return this killer shot. Physics explains how it works

Squash’s killer “nick shot” has a formula. It’s all about height and timing, a new study shows.

Two killer whales are shown rubbing a small piece of brown kelp between their bodies. One whale is to the upper left. The other is to the bottom right. The second whale's nose comes about halfway up the first's body, lining up with its dorsal fin.

Killer whales may use kelp brushes to slough off rough skin

A black circle perfectly blocks the sun in an artificial solar eclipse. The sun's corona and wispy rays radiate from it in lime green.

Two spacecraft created their first images of an artificial solar eclipse

A whale shark looks toward the camera in an underwater photograph. Black-and-white striped fish swim in front of the shark and a scuba diver is in the distance.

50 years after ‘Jaws,’ sharks face their own terror

A seal with speckled gray and black fur swims through an underwater kelp forest, facing the camera.

U.S. seal populations have rebounded — and so have their conflicts with humans
