Researchers have created the world's fastest nanoscale motor with "DNA origami." It could be the first step to nanobots that can deliver drugs and more.

Fish swimming in schools use less energy and move faster than those that swim alone. But school shape matters, too.

The way chameleons catch live insects in the blink of an eye could one day lead to soft robots capable of quickly and accurately completing automated tasks.

A long-term study finds that a simple test of walking speed may detect signs of aging at age 45, and that the brains of slower walkers were different in preschool.

A test of mobile typing speed reveals that the gap between mobile and desktop has narrowed. You can try the texting speed assessment for yourself.

Slothbot suggests fast isn't necessarily better—especially when it comes to monitoring the enviroment.

Flying cars could soon move from science fiction to reality. But how sustainable will they be?

Setting speed limits too far below engineering recommendations carries risks, new research finds.
