"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.

[–] MyTurtleSwimsUpsideDown@fedia.io 22 points 3 months ago

It’s not the fungi we asked for, but it’s the fungi we deserve.

The thumbnail looks like a sphincter

Radiation turns you black, instead of green, who knew..

[–] Goretantath@lemmy.world 41 points 3 months ago (5 children)

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

[–] Treczoks@lemmy.world 39 points 3 months ago (1 children)

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.

[–] jj4211@lemmy.world 27 points 3 months ago (1 children)

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...

[–] frongt@lemmy.zip 11 points 3 months ago* (last edited 3 months ago) (1 children)

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.

[–] village604@adultswim.fan 3 points 3 months ago

But, like any shielding, the thickness matters. And if this stuff could also convert CO2 to oxygen, having a bunch would be a good thing.

[–] a4ng3l@lemmy.world 30 points 3 months ago (1 children)

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.

[–] _stranger_@lemmy.world 6 points 3 months ago (1 children)

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

[–] a4ng3l@lemmy.world 9 points 3 months ago (3 children)

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

[–] _stranger_@lemmy.world 3 points 3 months ago (1 children)

bonus: you won't need eyes?

[–] a4ng3l@lemmy.world 2 points 3 months ago

Damn that was a rough one

[–] thebestaquaman@lemmy.world 3 points 3 months ago

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.

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).

In the future, instead of shooting up shiny silver rockets, we'll be firing up rockets covered in gross mold.

[–] qarbone@lemmy.world 2 points 3 months ago

Obviously you hide the gross fungi under a nice silvery façade. You don't compromise aesthetics in space or all the other stellar societies will laugh at us, and uninvite us from the quasar parties.

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

[–] MonkderVierte@lemmy.zip 2 points 3 months ago* (last edited 3 months ago)

You mean, digesting one of the dotzens of toxic Uran derivatives to thin air? I don't think so.

I for one welcome our melanin-pigmented overlords.

[–] anomnom@sh.itjust.works 7 points 3 months ago

Can’t go worse than the spray tanned ones.

[–] Windex007@lemmy.world 21 points 3 months ago

Life... uhhh...

[–] DandomRude@lemmy.world 20 points 3 months ago

The evidence that the fungi overlords will soon take over continues to mount...that's why I don't eat mushrooms...better safe than sorry...

[–] SlartyBartFast@sh.itjust.works 16 points 3 months ago (1 children)

I can't wait until we can lab-grow lignin, I'm talking 3D printed wood, mofuckas

[–] quick_snail@feddit.nl 5 points 3 months ago (1 children)

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

[–] SlartyBartFast@sh.itjust.works 17 points 3 months ago (4 children)

Because it won't be cheap when I escape into space

[–] Heliumfart@sh.itjust.works 5 points 3 months ago (5 children)

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.

You should call her a doctor

Everything reminds me of him

[–] MonkderVierte@lemmy.zip 6 points 3 months ago* (last edited 3 months ago)

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.

[–] t_berium@lemmy.world 3 points 3 months ago

So this is how the 40K Orks came to be! Makes sense.
