Holy cow, what a coincidence! Just yesterday was just reading through a paper on ArXiv and my mind was absolutely blown when I followed a citation and came across this same 2005 paper. The idea of a photosynthetic organism that runs off of thermal radiation is insane to me!
Sulphur Photosyntheses was here way before us, and it will probably be one of the last things left at the end if the solar system. Just not on earth cause our fate is to burn.
I was about to say the same. I heard there were some detractors because they emit most on the infrared spectrum, but here we are, on Earth, doing the same thing.
Photosynthesis is also possible in the pitch-black Chernobyl reactor building using melanin. It even may be possible to "photosynthesize" off of cosmic rays.
It's absolutely possible because when the universe underwent cool down period to now we know of, from the big bang, there were at least hundred of million light years that met at exact "life thriving" condition temperature before it went cold. So at that moment onwards, not-needed-water lives would have formed (or might be there were already a water environment existed) and stuck around the cosmo. Water was just a medium, another opportunity for them to thrive in different condition. Our universe could already exist all kind of lives in the past, and many of them "float around" in asteroids for example just waiting for the right condition to thrive in different forms, just like "we" were fortunate enough to land on earth. So, if we ever met "alien", we are actually come from the same big "cosmo" family
I wonder if the existence of photosynthetic bacteria that use infrared light on Earth increases the odds of finding life on planets around red dwarf suns.
Infrared (heat) is light... sorta... Never thought of it before however. It makes total sense. I wish we could synthesize vitamin D from the heater as well... it'd make our life much easier.
it just makes me think that while these bacteria must be way less effective/much slower at their jobs... theyd be an efficient source of proteins and medication given enough gene altering
Deep, it's just perspective. I love it's just photosynthesizing light, just beyond our visible spectrum. Reminds me of the patterns in UV on flowers insects see that we don't.
My thoughts exactly. If you think about it, there's no reason why photosynthesis would be limited to the light we just happen to be able to see.... Energy is energy.
@@Ziorac Energy may be energy, but the amount of energy carried matters a lot. Too low and it can't bump particles around (so lower energy than microwaves is unlikely to be enough). Too high and it'll break up your DNA, RNA and proteins, which is what makes what we casually just call 'radiation' i.e. high energy particles dangerous.
@@ArawnOfAnnwn I wonder as we explore more of Earth, the Solar system and maybe one day bodies in other solar systems if we could see things like specific conditions attenuating more harmful radiation into useful forms, maybe even wilder things like Diatoms that create a little shell of something around themselves to do the same.
@@Tuberuser187 You don't need to leave Earth to see that. We've already found some fungi species living in highly radioactive places like Chernobyl. And they don't seem to be merely surviving to eke out an existence there, but actually thriving in it.
This just reminded me of some French dude I heard of a decade or so ago who was touting the future of cars being based on, not batteries, but compressed air! Unsurprisingly I never heard of him or his compressed air cars ever again, so I guess it was all just a load of hot air. 😅
@@ArawnOfAnnwn On a related topic, I've read online that researchers are trying to use gene splicing to grow a fuel-free automobile, but I'll believe it when I see it! (or when I read about it on the net😉)

Can't but to ask why would the green sulphur need to be shielded from oxygen and does the purple-green use the oxygen? Only thing I can think of is that the oxygen by-product is poisonous just like booze is to yeast during fermentation.
Just goes to show that no matter how high entropy is (infrared light), it can always be driven even higher. Green sulfur bacteria extracting energy from what should be the noise.
Not convinced. If bacteria could synthesize using thermal IR say 1200K ~ 0.1 eV they could compete with visible region photosynthetic organisms. H2S as electron donor could be a restriction.
The relationship between cyanobacteria photosynthesis and green sulphur bacteria, purple sulphur bacteria and purple non sulphur bacteria is needed. I understand that our mitochondria are derived from purple non sulphur bacteria.
Infrared Radiation! It’s still technically Photons, but man, that’s like an order of Magnitude less energy than Green visible light! But in a vent, I suppose it’s about quantity of Photons over Quality. It never goes dark, and it never gets cloudy.
This is the first time i ever heard of a bacterium having an organelle within it. I never imagined that that was possible. Im wondering if there are any other examples of bacteria containing organelles. Is a bacterium that contains an organelle really a bacterium? Amazing.
@@jimzielinski946 I mean, ribosomes are pretty important, since their job is to read DNA/RNA and make proteins out of those instructions. It'd make sense that bacteria have them. I think flagella are also considered organelles, so those flagellates are indeed automatically bacteria with organelles :)
@jimzielinski946 that's literally the textbook definition of the difference between prokaryote and eukaryotes... lacking a nucleus and membrane bound organelles. It was definitely taught to you at some point because that's always in the first 3 chapters of any biology course
I’ve found algae growing in complete darkness. Inside our water storage tanks, that have never been opened since installation, we often get large swaths of algae with the water.
This made me wonder if these can use low energy infrared photons to produce energy, is it possible to use even lower energy photons like microwaves or even FM radio waves. xD
I think there's some lower limit here because a pigment molecule is going to have a hard time absorbing light that has a wavelength significantly longer than the size of the molecule or complex doing the absorbing. I think the limit is somewhere around half a wavelength, which would make anything larger than infrared really hard for a cell to absorb.
Aren't the 'vacuoles' in the purple sulfur bacteria just reserves of elemental sulfur, which can store energy for them they can then regain via sulfur oxidation? Not "gas bladders" as you say?
I was watching Children of Fire Mountain yesterday and wondering whether cooking your dinner in the hot springs would introduce bacteria,so this was fascinating.
You're probably thinking of sulfur-reducing bacteria like Desulfotomaculum nigrificans which convert amino acids like cysteine into hydrogen sulfide (H2S)
@@kailawkamo1568 I just never heard of anything that digests sulfates or sulfuric acid to sulphur or hydrogen sulfide, if such an organism existed it with have good synergism with these guys. Energetically speaking I'm not even sure it's possible
This seems to have implications for extraterrestrial life. Red dwarfs emit not much visible light but a lot of infrared. I heard it said this makes life unlikely on a planet around a red dwarf.
Man if you are capable of founding so much joy on vents that go on and off, the day you discover the "dark side" of Uranus you will die of euphoria. Knowing that, I have to say that your comments are a little bit self-centered...
So the green sulfur bacteria needs a purple Soldier bacteria to keep it safe from the oxygen or the purple like to move purple silver bacteria needs the green rest area or till needs the screen a symbiotic relationship with the two😎😎😎😎😎👍👍👍👍👍👍👍👍👍👍👏👏👏👏👏👏
It nay not be creative to name purple/green sulfur bacteria the same way, but it is convenient.
Most scientific names are equally uncreative, but in Latin or Greek.
Chlorosome just means "green body" in greek.
Chloroplast is "leafy green."

This is exactly the proof that photosynthesis is possible around Red Dwarf stars

Seems like a strong counterpoint to that claim that red dwarf stars couldn’t support photosynthesis.
The color contrast between the bacteria is so pretty
Water is pretty opaque in the IR spectrum. They wouldn't be able to wander much.
7:40 onward on the left side look at that spinny little guy go :D

Poor tardigrades.
Photosynthesis from infrared is absolutely mindblowing.
The molecules absorbing the radition must be huge!
Not really larger than visible light photosynthesisers

By definition; photosynthesis requires light.

This made me wonder if these can use low energy infrared photons to produce energy, is it possible to use even lower energy photons like microwaves or even FM radio waves. xD
First Law of Thermodynamics - energy isn't produced, it's transformed. Yes microwaves and radio waves carry energy. Very little.
I think there's some lower limit here because a pigment molecule is going to have a hard time absorbing light that has a wavelength significantly longer than the size of the molecule or complex doing the absorbing. I think the limit is somewhere around half a wavelength, which would make anything larger than infrared really hard for a cell to absorb.

Knowing very little of biology but a bit more about physics my answer was "yes" though I didn't know it would be infrared.
