The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role ...

Muscle-on-chip systems are three-dimensional human muscle cell bundles cultured on collagen scaffolds. A Stanford University research team sent some of these systems to the International Space Station ...

Ancient human relatives ran on two legs, like modern humans, but at a much slower pace, suggest 3D computer simulations of Australopithecus afarensis – a small hominin that lived more than three ...

Digital modelling of legendary fossil's soft tissue suggests Australopithecus afarensis had powerful leg and pelvic muscles suited to tree dwelling, but knee muscles that allowed fully erect walking.

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

It's no secret that our muscles begin to weaken as we age. But scientists are only just beginning to understand the mechanisms underlying these changes, and what our muscles can do to combat them. Our ...
