    That fungus is called Cladosporium sphaerospermum, and some scientists think its dark pigment – melanin – may allow it to harness ionizing radiation through a process similar to the way plants harness light for photosynthesis. This proposed mechanism is even referred to as radiosynthesis.

      And with a little CRISPR CAS-9, we can alter ourselves to become super-mutants or ghouls who can feed on ionizing radiation.

      Then, finally, I’ll be ready for the postapocalyptic nuclear wasteland.

      Proposed.

      I can’t find a single serious manuscript about radio synthesis.

      These fungi have robust DNA repair which allows them to grow without competition from yeast or bacteria.

      i mean, presumably the melanin just turns the radiation into heat? Which yeah is technically harnessing energy but it isn’t exactly creating ATP

    This is so cool - I interpret this to mean that life will be found throughout the universe, as this allows for some micro organisms to survive deep space

    Why else would life have this capability? Nature (evolution) prunes away unneeded features, so this capability, buried deep in various branches of life, is only useful when exposed to ionizing radiation…which only happens in deep space, or thru artificial means

    Buckle yer safety belts folks, we gonna find some crazy moulds and stuff every where its warm and wet, including places that are “warm and wet” in a nuclear sense

        …fine, they get “de-selected”, or whatever the correct term is, and it takes time a looooong time, I know

        Why else would DNA harbour an ability to eat gamma radiation if it had not been necessary?

        FYI: Adding some additional info, other than just saying “wrong” would def make for more interesting convos…just sayin

      i mean we are constantly bathed in ionizing radiation, just not that much of it.
      Plus, maybe life just evolved on earth a lot earlier than we thought? In that case it might well have been exposed to greater levels of radiation than we currently are.
