Astronauts have been able to track their muscle health in spaceflight for the first time using a handheld device, revealing which muscles are most at risk of weakening in low gravity conditions. An ...

Most kids dream of growing up to be astronauts; but the downside of spending extended amounts of time in low gravity is that astronauts’ muscles tend to shrink and weaken through disuse. Now, ...

Humans were not designed for space. Ironically, because we insist on going there anyway, scientists now know from studying astronauts that the lack of Earth’s gravity can wreak health havoc, such as ...

Early indications show that nutritional supplements may lessen muscle atrophy brought on by space travel, prolonged bed confinement or immobility. To study space travel’s effect on muscles, Dr. Robert ...

How can microgravity influence muscle regeneration and overall muscle loss in astronauts? This is what a recent study published in Stem Cell Reports hopes to address as an international team of ...

As astronauts lose muscle mass due to the microgravity environment in space, could there be a way to monitor it so they can take necessary steps to prevent further muscle loss? This is what a recent ...

On the Moon, taking a simple step could quietly damage your body. With weaker gravity, your muscles do less work, your bones carry less weight and, over time, both start to fade. That problem does not ...

A gentle rumble ran under a researcher's feet as a rocket carrying her research -- live, human muscle cells grown on scaffolds fixed on tiny chips -- lifted off, climbed, and disappeared into the sky ...

Sarcopenia, which is a progressive and extensive decline in muscle mass and strength, is common with aging and estimated to affect up to 50% of people aged 80 and older. It can lead to disability and ...
