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 ...

Astronaut muscles waste away on long space flights reducing their capacity for physical work by more than 40%, according to research published online in the Journal of Physiology. This is the ...

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, ...

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 ...

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 ...

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 ...

SpaceX is set to launch human muscle cells into space on Tuesday as part of a study that aims to further the understanding of the effects of ageing, according to scientists. The MicroAge study, led by ...

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 ...

Floating through the weightlessness of space, astronauts seldom need to flex their muscles. Slowly diminishing in size and strength, their wasting muscles struggle to support their weight when they ...

SpaceX is sending muscle cells to the International Space Station on Tuesday via a Falcon 9. It's part of a study by UK researchers who want to understand why muscles get weaker as people age. The ...

Researchers have found that nuclear factor E2-related factor 2, a master regulator of the oxidative stress response, affects muscle composition in microgravity. Targeting this protein could help ...
