Chernobyl‘s Radiation-Eating fungus: A Potential Shield for Space Travel?
Table of Contents
A remarkable revelation within the ruins of the Chernobyl Nuclear Power Plant has captivated scientists: a black fungus that appears to not only tolerate, but actively thrive on, radiation. This resilient organism, identified as Cladosporium sphaerospermum, is now the subject of research exploring its potential to shield astronauts from the dangers of cosmic radiation during space travel.
Discovery Inside the Reactor
The fungus was first identified in May 1997 by Ukrainian scientist Nelli Zhdanova during a survey of the destroyed reactor building. Zhdanova observed the melanin-rich mould colonizing the walls and ceilings, and her initial research revealed a surprising characteristic: the fungal hyphae were growing towards sources of ionizing radiation, rather than simply surviving in their presence.
Radiosynthesis: Converting Radiation into Energy?
Further inquiry in 2007 by nuclear scientist Ekaterina Dadachova at the Albert Einstein College of Medicine demonstrated that melanised fungi grew 10% faster when exposed to radioactive caesium compared to control samples. This led Dadachova to propose the concept of “radiosynthesis”-a process by which organisms could possibly convert radiation into metabolic energy.
Testing in Space: The International Space Station Experiment
To explore this possibility further,samples of Cladosporium sphaerospermum were sent to the International Space Station (ISS) in December 2018. Over a period of 26 days, the fungus grew an average of 1.21 times faster in space compared to identical samples maintained on Earth.
Cautious Optimism and Future Research
While thes results are promising, researchers remain cautious about definitively attributing the accelerated growth solely to radiation harvesting. Nils Averesch, a biochemist at the University of Florida and co-author of the ISS study, notes that the unique conditions of zero gravity could also be a contributing factor. Further research is needed to fully understand the mechanisms at play and determine the true potential of this remarkable fungus.
The implications of this research are significant. If scientists can unlock the secrets of radiosynthesis, it could pave the way for developing innovative radiation shielding technologies, not only for space exploration but also for applications in nuclear remediation and medicine.
