Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

MIT scientists find that motor neuron growth increased significantly over 5 days in response to biochemical (left) and mechanical (right) signals related to exercise. The green ball represents cluster ...

There’s a robust molecular language being spoken between your muscles and your brain. We’ve often thought about muscle as a thing that exists separately from intellect—and perhaps that is even ...
