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 ...

These mice are making gains in microgravity. Weightlessness makes it pretty hard to push, pull, lift or perform any other sort of athletic task. In less than two weeks of space travel, astronauts can ...

Back in December, a collection of 40 mice (as in rodents, not computer peripherals) was delivered to the International Space Station aboard a SpaceX rocket for a one-month stay. While some of these ...

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 ...

Findings from the “Mighty Mice” investigation on the International Space Station (ISS) may help “save the day” both for earthbound patients with muscle and bone loss as well as astronauts on prolonged ...

A sojourn in space is a great way to ruin one’s physique — the microgravity results in dramatic loss of muscle mass. Residents of the International Space Station exercise regularly to stave off the ...

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 ...

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 ...

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 ...

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 ...
