"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."

You want Hulk fungi?

Because this is how you get Hulk fungi.

It's even approximately that shade of green.

    3.6? Well it's not great, but it's not terrible.

    And the high-range dosimeter from the safe burned out immediately. It must have been faulty!

    Funniest/saddest moment from that miniseries was when their officials have the West the propaganda numbers to build the robot. Fucking lol...

    Does this fungus "eat" the radiation, as in we can use it to clean up radioactive areas? Cause that'd be nice.

    Sadly, no. Radioactive processes happen without any external control (at least not on this level, they don't run a reactor or accelerator), and this fungus only harvests the energy.

    Akin to how plants photosynthesize without doing anything to the sun.

    At least there it does provide shade, though I doubt the fungus would provide a whole lot of shielding...

    If it's absorbing the energy, then it's not passing through. That's shielding.

    But like light shining through a plant's leaves, it probably doesn't absorb anywhere near all the energy, so probably not useful as actual shielding material.

    Well if it just evolved this ability that suggests it found a unique niche. But it probably hasn't optimized this, since it doesn't have any pressure to compete against other organisms for the radiation source.

    But the good news is that we could selectively breed the fungus, or even generically engineer it (once the genes are isolated) to maximize the ability much faster.

    I don't know how useful it would be for site cleanup but it might at least become good insulation (like the idea of space station shielding mentioned in the article).

    One potentially useful thing that they could be used for is finding radioactive contamination. Presumably it grows best at higher radiation, so instead searching with ginger Geiger counters for radioactive contaminants you could spread this stuff out over the environment, then just look for where it is growing a while later. Engineer it to be bright orange or something.

    It eats the radiation, not its source though. The emitter would have to be removed. Maybe it could be used in shielding ? Like in space where background radiation seems to be a problem.

    It needs carbon to grow, so it would be a CO2 scrubber AND a source of food assuming it's edible. 🤔🤔🤔

    I would not be eating something with a radioactive-based diet in space… that’s like 2 steps away from opening the gates of hell of something like that xD

    Fantastic thing though: It doesn't "eat" radiation in the sense that it becomes radioactive itself. It just absorbs the energy from the radiation, like plants absorb sunlight, to power a synthesis that lets it convert CO2 to organic material.

    Like everything nuclear, it's a double edge sword. Clearing up nuclear power would be amazing. People knowing they can Nuke something and eradicate the after effects quickly

    Why would you want to take something that's cheap and make something that's wayy more expensive?

    I love the idea of cracking methane brought in from Kuiper belt objects, and growing massive cubes of artificial wood with giant orbital solar arrays. In some future where this was possible, with a delivery system to the surface (maybe deorbiting into the ocean), we could theoretically curtail most deforestation on the planet.

    Returns are gonna be rough when Home Depot Orbital/Galactic drops a huge stack of bent 2x4s from orbit directly into your backyard. "Just take them back where you bought them."

    Having said that, "tree" satellites sound pretty cool.

    Extract the gene and inject it into a roach. Then encode human DNA into roach eggs and fly those roaches to Mars. After a few generations we would have a fully grown man roach able to feed off the radiation. That's as far as I've gotten that idea. Oh man, tomorrow is another fuckin Monday. But we're just 5 more weeks from 2026 can't wait to 2029 when we'll have a new president. Thanks electoral college! Without you we wouldn't be able to choose the most retarded possible person for the job. I hope you guys eat some psychedelics this time around. Sure we could also choose whatever the public picks. Wait, what was the question?

    What was it again. A bacteria in a pocket in some Uran mine, that directly uses radiation as energy source? Might be yet another mechanism.
