Self-healing material twitches like muscle

Jolting a super-stretchy, self-healing material with an electrical field causes it to twitch or pulse in a muscle-like fashion. The polymer can also stretch to 100 times its original length, and even repair itself if punctured.

Predicting self-assembly in natural materials

Nature’s toolkit includes its still-matchless ability to effortlessly assemble proteins, membranes, and other complex structures from parts lists of atoms, molecules and particles of various sizes and shapes.
