All runners, according to a popular school of training thought, can be divided into two categories: slow-twitch and fast-twitch. Physiologically, this idea rests on pretty shaky ground. The old view ...

The research team anesthetized a set of mice and then either injected the animals’ hind limb muscles with a cardiotoxin or made manual incisions into the muscle. The striated muscle tissue began ...

Artificial muscles made from twisted fibers could offer a compact and lightweight alternative to conventional motors in applications such as miniature robots or medical implants. But these synthetic ...
