Genetic model reveals a form of calcium release is unnecessary for normal muscle contraction
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 ...
First hominin muscle reconstruction shows 3.2 million-year-old ‘Lucy’ could stand as erect as we can
A Cambridge University researcher has digitally reconstructed the missing soft tissue of an early human ancestor – or hominin – for the first time, revealing a capability to stand as erect as we do ...
One of the most famous fossils in human evolutionary history is known as "Lucy," who belonged to an extinct species called Australopithecus afarensis—an early relative of Homo sapiens who was among ...
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 ...
First hominin muscle reconstruction shows 3.2 million-year-old 'Lucy' could stand as erect as we can
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.
