Summary

Story summary

The fungus Cladosporium sphaerospermum, found at the Chernobyl disaster site, grows faster in radioactive environments and may use radiation for energy through radiosynthesis.
Researchers initially credited melanin for protection, but newer studies indicate other biological components may also contribute.
Experiments aboard the International Space Station show the fungus could act as a protective barrier against cosmic radiation.
This suggests a potential biological shielding approach for future Moon or Mars habitats.
