Radiosynthesis

Using a robot to explore the inside of the reactor at Chernobyl, scientist came across a black fungus that was able to live inside the abandoned facility where the radiation level is 500 times the background level. Many fungi are pretty resistant to radiation, so that's not the extraordinary part. Scientist think that the fungus is actually converting radioactive energy into biological energy it can use to grow. The reason the fungus is black is due to a large amount of melanin which scientists believe is being used in a similar way as chlorophyll is used in plants to convert solar energy into biological energy.
