Are astronauts aging faster in space? A groundbreaking new study from UC San Diego reveals that human stem cells — specifically the ones responsible for blood and immune system health — may age more rapidly during spaceflight aboard the International Space Station. The study observed DNA damage, reduced regenerative ability, and shortened telomeres, all signs of accelerated aging caused by microgravity and radiation.
But here’s the surprising twist — some of this aging may be reversible! When the cells were brought back to Earth and placed in a healthy environment, they started to recover.
This discovery doesn’t just change how we protect astronauts — it could also unlock secrets about human aging and diseases like cancer right here on Earth.
