Chernobyl Fungus Eats Radiation, Offers Space Shield

In the shadow of the Chernobyl nuclear disaster, scientists have identified a remarkable black fungus, Cladosporium sphaerospermum, that not only survives but actively thrives on radiation. This radiotrophic organism possesses the unique ability to convert gamma rays into chemical energy, a process scientists are calling 'radiosynthesis.' Its resilience and growth are significantly enhanced by radiation exposure.

NASA is now investigating the potential of this fungus for groundbreaking applications, including the development of 'fungal bricks.' These could serve as lightweight yet highly effective building materials for lunar and Martian habitats, offering superior protection against cosmic radiation compared to traditional heavy shielding. Studies on the International Space Station have already demonstrated the mold's rapid growth and significant radiation-blocking capabilities.
