Could Squirrels Be the Key to Long Distance Spaceflight?

The video explores the challenge of muscle loss in astronauts due to microgravity and examines how hibernating animals like bears and ground squirrels maintain muscle mass. Research on bears and mice has shown that hormones and genes play a role in muscle preservation. Ground squirrels use gut microbes to recycle nitrogen, preventing muscle atrophy. This process could potentially be applied to humans, offering a way to maintain muscle mass during long space flights or for those who are bedridden. Further research is needed to develop practical solutions for humans.
