Defects in mitochondria may explain many health problems observed during space travel

For space exploration to be successful, it’s vital to understand—and find ways to address—underlying causes of the health issues that have been observed in astronauts who have spent extended periods of time off world. These problems include loss of bone and muscle mass, immune dysfunction, and heart and liver problems. Using data collected from a number of different resources, a multidisciplinary team is reporting discovery of a common thread that drives this damage: mitochondrial dysfunction. The researchers used a systems approach to look at widespread alterations affecting biological function. The findings are reported November 25 in the journal Cell.
