Summary:
- A new study suggests that the International Space Station (ISS) may have too few germs, which could be a concern for astronauts' health.
- Researchers found that the microbial diversity on the ISS is lower compared to similar built environments on Earth, potentially leading to an imbalance in the microbiome.
- The study highlights the importance of maintaining a healthy microbial environment on the ISS to support the well-being of astronauts during long-duration space missions.
