Mold from Chernobyl seems to feed on radiation, and new research suggests it could help protect astronauts in space
Researchers took mold that grows in the Chernobyl exclusion zone and blasted it into space. It may help protect astronauts from radiation.

Geiger counters then measured radiation levels beneath the dishes every 110 seconds for 30 days. The results showed that radiation levels decreased at the height of the mold's growth: The counters measured a 2.4% decrease in average radiation levels beneath the mold-covered sides.
