Chernobyl Fungus Hints at Radiosynthesis: Melanin May Turn Radiation Into Energy
Scientists studying the black fungus Cladosporium sphaerospermum in the Chernobyl Exclusion Zone report it grows better in ionizing radiation, possibly via a radiosynthesis-like process in which melanin could harvest energy while shielding the fungus from damage; though earlier work suggested a photosynthesis‑like pathway and a 2022 ISS experiment showed radiation shielding, a concrete energy-harvesting mechanism remains unproven, leaving the exact purpose of radiation tolerance uncertain and highlighting life’s adaptations in extreme environments.
