Summary:
- Spending time in space can have significant effects on the human body, including changes to our cells. Researchers have studied astronauts aboard the International Space Station (ISS) to better understand these changes.
- One key finding is that space travel can cause DNA damage and alter gene expression in human cells. This is likely due to the increased radiation exposure and microgravity conditions experienced in space.
- The insights gained from studying how space affects our cells can help scientists develop countermeasures to protect astronauts' health during long-duration space missions, such as future trips to Mars.
