Long-duration space flight equal to decade of bone loss in astronauts, study says

Science
July 1 (UPI) -- Scientists have long known that astronauts lose bone density while in space, but a study published this week found they only partially recover this loss one year after returning to Earth. The researchers said the findings suggest long-duration spaceflight is equal to decades of bone loss in weight-bearing bones on Earth. The extent of the impact, though, varies depending upon the subject. Bone loss happens because bones don't have to carry your weight in microgravity, meaning astronauts use them less, leading to weakening. "Bone loss happens in humans -- as we age, get injured, or any scenario where we can't move the body, we lose bone," said Leigh Gabel, assistant professor in kinesiology at the University of Calgary and lead author of the study. The researchers scanned ...
