The mysterious black fungus from Chernobyl that may eat radiation

Mould discovered at the Chernobyl nuclear disaster site seems to thrive by consuming radiation. This discovery raises the question of whether it could be used to protect space travelers from cosmic radiation.

Radiation-eating fungus

At Chernobyl’s highly radioactive environment, scientists found a type of black fungus growing on the walls. Unlike most organisms harmed by radiation, this fungus appears to absorb and feed on it.

The fungus contains melanin, a pigment also found in human skin, which may convert radiation into chemical energy, similar to how plants use chlorophyll for photosynthesis.

Potential applications in space travel

Researchers are intrigued by the possibility of using this fungus as a natural radiation shield for astronauts. The idea is that it could be grown on spacecraft surfaces or astronaut suits, providing a biological barrier against harmful cosmic rays during deep space missions.

Scientific observations and challenges

Studies have observed that the fungus grows faster in the presence of radiation. However, there are challenges before it can be applied in space, such as understanding its growth limits, survival under different conditions, and ensuring safety for humans.

“This fungus seems to transform radiation into energy, much like plants use sunlight,” said one scientist involved in the research.

Implications beyond space

Beyond astronaut protection, understanding how this fungus thrives in radioactive zones could help in bioremediation — the use of living organisms to clean up contaminated sites on Earth.

This fungus from Chernobyl’s dangerous environment highlights the potential of nature to adapt uniquely, opening doors to innovative radiation protection strategies in space and on Earth.
