Scientists Create a New Kind of Liquid That Can Push Itself Along a Flat Surface - PHYSICS

Moving a liquid from point A to point B typically requires either a sloping surface or a pump of some sort to apply pressure.

A new kind of material that is in early development requires neither, instead relying on a squirming skeleton of microscopic fibres to move it in a direction, opening the way for a class of fluid capable of worming itself through a channel.

Researchers from Brandeis University in Massachusetts took a hint from nature and investigated how the biomechanical properties of materials called microtubules could be applied to a mixture to make it move in a single direction around a container.
