Losing muscle strength is a natural part of aging. At the core of this decline is a drop in the number of muscle stem cells ...

When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

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 ...

Muscle stem cells, which are crucial for building new muscle, don’t work as well as we get older, but giving them an ...

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 ...

In a recent study published in NPJ Microgravity, scientists explore the impact of spaceflight on human vascular smooth muscle cells at the transcriptomic level. Study: Spaceflight effects on human ...

Sometimes nature provides the best blueprints for building effective robots. It also can provide the best material. Billions of years of natural selection has built some pretty impressive machinery, ...
