Research suggests women lose more muscle than men in spaceflight

New research published ahead of print in the Journal of Applied Physiology suggests women lose more muscle than men in a microgravity environment such as spaceflight. The study "represent[s] the longest bed rest study on ...

Counteracting bone and muscle loss in microgravity

In microgravity, without the continuous load of Earth's gravity, the tissues that make up bones reshape themselves. Bone cells readjust their behaviors—the cells that build new bone slow down, while the cells that break ...
