There Is a Species of Fungus That Eats Radiation

In the aftermath of the 1986 Chernobyl nuclear disaster, within the ruins of the highly radioactive reactor, scientists made an astonishing discovery. Black-pigmented fungi were not only surviving but appeared to be flourishing, with some growing directly towards the sources of intense radiation. First identified in 1991, these organisms, including species like *Cryptococcus neoformans* and *Cladosporium sphaerospermum*, demonstrated a remarkable adaptation to an environment lethal to most life forms. This phenomenon, termed radiotropism, suggested that the fungi weren't just resisting the radiation but were actively drawn to it.

The secret to this unusual ability lies in melanin, the same pigment that gives human skin its color. In these fungi, melanin absorbs the harmful gamma radiation and converts it into a usable form of chemical energy. This process, known as radiosynthesis, is analogous to how plants use the green pigment chlorophyll to convert sunlight into energy through photosynthesis. Essentially, the fungi are "eating" the radiation and using it to fuel their growth, a capability that has opened up new avenues of scientific research.

This unique biological process has profound implications, particularly for the future of space exploration. The harsh radiation of space is a major obstacle for long-term missions. Scientists are now investigating how these radiotrophic fungi could be used to create living, self-replicating radiation shields to protect astronauts and equipment. Experiments conducted aboard the International Space Station have already shown promising results, suggesting a thin layer of this fungus could significantly reduce radiation levels, potentially making long-duration travel to destinations like Mars safer for humans.
