Imagine being chased by a swarm of robots that just would not stop no matter how many of its parts have already been destroyed. It sounds like a scene from science fiction, but the technology is ...

Particle robots are made of identical particles that interact weakly via magnets. These particles do not have individual locomotion abilities but can only expand and contract. Collectively, the robot ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

Taking a cue from biological cells, researchers from MIT, Columbia University, and elsewhere have developed computationally simple robots that connect in large groups to move around, transport objects ...

In physics, particles are small localized objects with physical characteristics like mass or volume. From those humble ingredients, our virtually limitless universe is built. The concept, presented in ...
