"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 17 points 19 hours ago

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

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

[–] ExhaleSmile@lemmy.world 26 points 1 day ago (2 children)

The meter only goes to 3.6!

[–] Madrigal@lemmy.world 24 points 1 day ago (1 children)

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...

[–] Madrigal@lemmy.world 3 points 1 day ago

West Germany, though, so you can imagine how that conversation went.”

[–] Black616Angel@discuss.tchncs.de 2 points 21 hours ago

I don't know it for sure, but I understood that the Germans built a robot capable of withstanding the propaganda number not explicitly for the Russians. It just happens to withstand those, but not the real numbers...

This looks like one of those bad conversions to imperial- instead of 3.28 feet per meter, your spaceship crashes into the surface

[–] Zachariah@lemmy.world 5 points 1 day ago

it’s out of 3

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 34 points 23 hours 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 20 points 17 hours 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 6 points 15 hours ago* (last edited 15 hours 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 2 points 11 hours 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.

[–] Deconceptualist@leminal.space 23 points 23 hours ago* (last edited 23 hours ago) (2 children)

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).

[–] AA5B@lemmy.world 1 points 18 hours ago

We could breed it to incorporate radioactive particles to make it independently self-sustaining

[–] Cethin@lemmy.zip 1 points 11 hours ago* (last edited 3 hours ago)

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.

[–] a4ng3l@lemmy.world 22 points 16 hours 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 1 points 10 hours 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 5 points 10 hours ago (1 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 10 hours ago (1 children)

bonus: you won't need eyes?

[–] a4ng3l@lemmy.world 2 points 7 hours ago

Damn that was a rough one

[–] sirico@feddit.uk 2 points 22 hours ago

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 20 hours ago* (last edited 20 hours 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 21 hours ago

Can’t go worse than the spray tanned ones.

[–] Windex007@lemmy.world 17 points 1 day ago

Life... uhhh...

[–] DandomRude@lemmy.world 17 points 1 day 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...

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

[–] quick_snail@feddit.nl 5 points 16 hours 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 13 points 16 hours ago (2 children)

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

[–] Heliumfart@sh.itjust.works 4 points 14 hours ago (1 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.

Too bad that humanity is obsessed with such stupd shit.i

It's cool that that letter migrated seven spaces over.

They have a life of ther own. i

I hope you're able to get mental health services

[–] SlartyBartFast@sh.itjust.works 4 points 10 hours ago

what, in space? I don't think that falls under the scope of "universal" health care

[–] MonkderVierte@lemmy.zip 6 points 20 hours ago* (last edited 20 hours 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.

[–] altphoto@lemmy.today -2 points 23 hours ago

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?
