Mice sent to space for understanding ageing process


Washington: The National Aeronautics and Space Administration (NASA) said  mice sent aboard the International Space Station (ISS) will help understand ageing.

According to reports, the Rodent Research-8 (RR-8) will examine the physiology of ageing and  its effect of age on disease progression.

NASA said in a statement that groups of young and old mice flown in space and kept on Earth for the purpose of investigation.

“The objective is to expose the mice to microgravity and track physiological changes,” said Michael S Roberts, deputy chief scientist at the US National Laboratory, a sponsor of the investigation.

“Tissue samples from space-flown animals are extremely valuable to biomedical research and opportunities to use the space station are limited to a few missions each year,” Roberts said.

The reports said previous research has shown that spending time in space causes bone density loss, immune dysfunction, cardiovascular issues such as stiffening of arteries, and loss of skeletal muscle mass and strength in both humans and rodent models.
