    Unusual property of the ultrastrong material could be harnessed for twisting or pulling motions. Researchers have found that spider silk produces a strong twisting motion when exposed to humidity, and may be usable for future artificial muscles or actuators. Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found.

    The resilient fibers, the team discovered, respond very strongly to ...
