Scientists have built microscopic, light-powered robots that can think, swim, and operate independently at the scale of ...

Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

Researchers have created microscopic robots so small they’re barely visible, yet smart enough to sense, decide, and move completely on their own. Powered by light and equipped with tiny computers, the ...

Scientists have created robots smaller than a grain of salt that can sense their surroundings, make decisions, and move ...
