Giant single-celled organism contracts 10 times faster than human muscle
In under five milliseconds, the giant single-celled organism Spirostomum ambiguum can shrink to one quarter of its length, contracting ten times faster than human muscle fibers. Driven by a fishnet-like, calcium-activated protein network rather than conventional muscle, this rapid mechanism helps the ciliate escape predators and communicate. Decoding this capability offers inspiration for engineering faster artificial muscles and advanced...
