Scientists turned simple knots into tiny robots that jump, spin, and plant seeds, offering a new tool for ecosystem restoration.

A simple idea has led to a surprising invention: tiny robots made from knotted fibers that can jump, spin, glide and even ...

However, if the elasticity and material are carefully selected, the knot itself becomes an active system, explains Shu Ya ...

When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot ...

Using a dual-material fiber that consists of a stiff Kevlar core and a surrounding shell of liquid crystal elastomer (LCE), ...
