Inside the abandoned, radioactive ruins of Chernobyl, scientists discovered a unique black fungus that doesn’t just survive radiation—it actually grows stronger because of it. Known as Cladosporium sphaerospermum, this fungus contains high levels of melanin, the same pigment found in human skin. But instead of protecting against sunlight, the melanin in this fungus acts like a natural solar panel, absorbing harmful ionizing radiation and turning it into energy the fungus can use.
This process, called radiosynthesis, works similarly to photosynthesis in plants, but it uses radiation instead of sunlight. First found in 1991 and studied more deeply since 2007, the fungus has shown remarkable ability to survive in extreme environments. Scientists even sent it to the International Space Station, where it grew quickly and showed potential as a natural shield against space radiation for astronauts.
Beyond space, this fungus could have real-world applications on Earth. It might help clean up explosive waste sites, protect people working in radioactive areas, or even assist future Mars missions by providing natural radiation protection. Its ability to thrive in one of the most riskiest environments on the planet makes it an extraordinary example of how life can adapt in unexpected ways.
