In 2014, NASA sent young and older mice into space; within 9 to 11 days, the younger ones began running group laps in zero gravity

In 2014, NASA launched a group of twenty mice to the International Space Station for groundbreaking research. Remarkably, the young mice exhibited coordinated circling behavior just two weeks after their arrival. In contrast, older mice showed little interest in this peculiar behavior, a mystery that intrigued scientists. This phenomenon could be connected to factors like stress, motivation, or the vestibular system.
