Scientists have shown the method to develop tiny, self-powered swimming micro-robots, and just from the use of three simple ingredients. The method involves combining oil drops with water containing a ...

Researchers introduces the first toroidal, light-driven micro-robot that can move autonomously in viscous liquids, such as mucus. This innovation marks a major step forward in developing micro-robots ...

When you're just a few microns long, swimming can be difficult. At that size scale, the viscosity of water is more like that of honey, and momentum can't be relied upon to maintain forward motion.

The oil droplets use fluctuating temperature changes in their surrounding environment to store energy and to swim. When cooled, the droplets release thin 'tail-like' threads into the environment. The ...

Just a few short years ago the popular Uncle Kracker song that included the (somewhat creepy) lyrics:: “… swim through your veins like a fish in the sea…” was a figurative, rather than a literal image ...
