NASA Learns More About Bone Loss in Space - Universe Today
New NASA-funded research has revealed how bone loss from long-duration spaceflight can increase the risk of injury to astronauts. A research team used three-dimensional X-ray scans to study the bones in 14 US and Russian crewmembers of the International Space Station. They found that the astronauts lost up to 2.7% of their bone mass every month, and additional exercise would be necessary to decrease the loss. This research will also help study the loss of bone density in the elderly.
