Imagine a liquid that could move on its own.

No need for human effort or the pull of gravity. You could put it in a container flat on a table, not touch it in any way, and it would still flow.

Brandeis researchers report in a new article in Science that they have taken the first step in creating a self-propelling liquid. The finding holds out the promise of developing an entirely new class of fluids that can flow without human or mechanical effort. One possible real-world application: Oil might be able to move through a pipeline without needing to be pumped.

Researchers recreate the system that causes cells to change shape. The result: a liquid that can move by itself.
