Algae is one of the oldest and most abundant forms of life on planet Earth, so it only makes sense that it offers a ton of solutions to unsustainable modern problems. Here are five ways in which algae continues to reshape the world.

Based on the title I was really hoping for evidence that algae might surpass humans as the dominant species. But this is cool too.
Bro we are humans, nothing can take over this planet until we're here abusing destroying every species for our own needs. 🤣🤣
@@ArawnOfAnnwn craaaab people
Craaab people
@@ArawnOfAnnwn crab rave
@@sicfxmusic like most species does then? using the environment to THEIR advantage. humans aren't the dominant species. plants are, they outnumber and weigh more than all humans if they where to be piled up.
@@no1Liikeglenn You are the smartest person I have seen on TH-cam, your IQ must be 6969 😲
You had me at biofilm. I dealt with it clinically on prosthetic heart valves, vascular catheters, ECMO tubing, VADs, etc. These pure science discoveries make me optimistic (and happy).
Me too I’m on dialysis and have also had many skin grafts for wounds from my autoimmune disease wegeners granulomatosis.
And hopelessly deluded.
Hearing the words "photosynthetic skin-graft" immediately conjures a mental image of science-fiction-y plant-people who can go for longer without eating and stuff. I'm sure this technology is nowhere near that level, but it's at least a fun thing to imagine.
@@ArawnOfAnnwn
And by “energy efficient” I assume that primarily means “no brains or muscles or the fun stuff that makes for a sapient being”
I also immediately thought of some sci-fi future where humans are grafted with some sort of SUPER algae (enough to power the complexities of the brain) and these half-plant humans survive where non-grafted humans cannot. OFF TO THE KEYBOARD I GO!!!!
@@ArawnOfAnnwn I have, any deciduous plant gets depressed every winter
Wasn't that Quiet from metal gear ?
The skin graft application is particularly interesting to me, since something like that would conceivably ALSO be very helpful for people who have had diabetes a long time. A frequent and common problem for diabetics involves diabetic ulcers - places on the skin that get too much pressure (ie the feet), or even just places on their extremities getting injured and then not healing properly. The major cause of that problem with healing back is down to blood flow: in other words, not enough oxygen getting to those cells. So a graft of this kind might make a much better treatment for such wounds. Maybe it could also be used to help cover burn wounds too.
When my husband burned his hand they used a sterilized pig skin graft. The plant based solution would be cruelty free.
@@marjohnsmusings3222 Scientific Watch-Suggests cause the Learning never Ends:
Want such?
And here I was just thinking how cool it would have been to have the ability to breathe using your skin... Coz as an asthmatic person, it would literally save me from this incurable disease and finally start doing stuff I couldn't before
Do you want a Swamp Thing? Because that's how you get a Swamp Thing.
I thought this would be about some catastrophic algae overgrowth scenario.
Lol yeah like attack of the big green algae blob.
Green goo
That’s why eutrophication happens after algae grows rampant.
Same here.. even their thumbnail was misleading
I thought it would evolve and become sapient.. now I’ve got an idea for a speculative evolution scenario!
Why is there evil laughter coming from my fish tank?
😂
I, for one, welcome our new autotrophic overlords.
Nah fam, robots gonna be our masters
@@BLOODKINGbro The A.I. in those robots are our new gods.
Yes! Proud to be contributing to the development of feasible large scale production systems for algae with a MSc thesis @ Wageningen University & Research! 😃
I help produce algae by taking too long to clean the fish pond in my yard.
From what I could understand, the "self cleaning" one may explain why feeding algae to cattle reduces their methane emission. It probably affects their rumen microbiome. I would like to see more research on that, looks interesting.
I am yet to recheck that paper though, but there are experiments on algae fed cattle and the clear drawback is that although it decrease methane emissions, so does the weight gain of the cattle.
Although there are arguments saying that we haven't had enough research on the algae that can reduce cow gas emissions without sacrificing weight gain.
I find it fascinating how stressed organisms - like algae with omega-3s and turning red when exposed to excess sunlight - evolve and devote mechanisms to protecting themselves from negative effects, like how the Chernobyl exclusion zone fungi produced copious amounts of melanin in order to protect themselves from radiation and devote its energy for growth and even DNA repair (which is likely going to be highly useful in any Mars expedition in the future due to fungi’s ability to “eat” metal/rocks and transform them into usable dirt while also producing useable substances in their mycelium. The addition of radiation to their diets can further allow them to grow and shield astronauts from radioactive damage). Melanin seems to be a common molecule for remediation - everything from eels in highly heavy metal rich areas and pigeons with similar conditions will use melanin to bind to bio toxins in order to secrete or augment their effects. In the future, I believe melanin could be used to capture heavy metals/toxins in the bloodstream (or simply in the hair) and be reappropriated to the skin where they would be sweated out and thus removed from the body - much like how melanated pigeons capture heavy metals in their darkened feathers where they are then shed and thus removed.
Interesting comment that will lead you down a proverbial rabbit hole, Thank you for that.
@@ArawnOfAnnwn they can store and sequester it/incorporate it in their mycelium - and thus are great for storing/moving heavy metals or radioactive materials. They can’t actually use it for energy like they can - and lichen can - with rocks.
The fungi in the nuclear reactor actually feed of the nuclear radiation. The melanin is able to produce electrons that power biological reactions. They are called radiotropic fungi and there are a few of them and are excellent living radiation shields that could also potentially produce food and medicine.
Nasa is investigating its use in outer space.
This could also be used in nuclear waste storage facilities or even protective suits.
Also the electrochemical properties of melanin make it a potential candidate for solar panel doping and microchip doping. The future is wild.
@@ArawnOfAnnwn they produce 97 percent of the oxygen you breathe and almsot 90 percent of the soil you use to plants crops.
Pretty cool stuff, though, it is worth pointing out that most (if not all?) algae are not plants; they're protists.
Algae are not plants. Thanks for pointing this out.
I think the show is kinda using this language to be more audible for people who arent aware that algae arent plants, i was today years old when I found out through your comment 😅
On the sunscreen tip, no need to wait for algea sunscreen to avoid oxybenzone...use zinc/mineral sunscreen! Perfectly natural and non harmful
Algae has always ruled the world, and likely always will. Next to it, all other plant life is insignificant.
Scientific Watch-Suggests cause the Learning never Ends:
Want such?
I agree!
This is awesome. Photosynthetic skin grafts are very promising. Alge is awesome 😎
Now on to a silly question. Could we one day be able to use those skin grafts to make humans able to photosynthesize? All of the time
@@ArawnOfAnnwn Maybe the extra oxygen could be nice for prolonged aerobic activity, as in being an endurance enhancer?
@@ArawnOfAnnwn That's actually only true because they spend a lot of their time GROWING.
Growth is extremely energy intensive, which is why baby animals eat so much more than adults.
@@omegahaxors3306 but aren't humans growing too? Even after puberty, the body still replaces cells
@@someyetiwithinternetaccess1253 True but maintaining an existing body is a lot cheaper than doubling in size over a few years.
@@omegahaxors3306 if we are just looking at that, then yes, you are correct. But humans have to do much more than that, we have sentient thoughts unlike plants, and those consume much, much more energy
Amazing, I was just randomly wanting to know more about algae, and here this video is!
Simplay wow thank you so much for all you guys hard work !
Always interesting, thanks.
This is a great lecture.
Structural features of Marine algae (Green seaweed).
1. Cells have nine pigments.
2. Cell pigments are converting chromaticity into a signal transduction system.
3. Cellulose is living cells.
Love these shows
This is an excellent episode.
They capture more of the sun's energy and produce more oxygen than all plants combined. They form the foundation of most aquatic food webs, which support an abundance of animals.👍
This is really cool. Makes me want to join up with GreenWave and become an ocean farmer. There's so much potential there. Also, an algal based skin graft sounds really cool.
This is exciting stuff
Plants survived an extinction event of their own creation, and they will survive the one of our creation as well
Plönts: "First time?"
The segues and the puns are spot on this episode
This is fantastic!This proves that we have game-changing,sci-fi technology.All it needs is a bit of innovation from us to take humanity to the next level!
SciShow is getting better again.
that is so cool!
I love it!
Realy excited about self cleaning
Algae are amazing there used for housing and windows ECT aswell
Epic video
the thumbnail is really cool.
Algae are fascinating!
Wow! Flipping wow
You did an episode on phytoplankton a couple of years ago. It is surprising that you didn't seem to mention it, unless I missed it.
I love Scishow so much.
I know you don't have any context for why that's alot for me to say but much like my namesake I'm quite bitter.
Ahh, this is the content that I live for: Good ol' Scrotal Acidosis
That skin graft could give rise to the next Marvel superhero.
I'm never gonna look at the alge in my terrarium the same way ever again
Michael with long hair is a mood that I wasn't prepared for. 😘
Algae have actually been playing this role for thousands of years. Hopefully they will resignify the fuel of the future. 🌱♻️💚

Shameless plug for my homies over at Wander Alpine! They're making skis and snowboards out of algae
I don't know, man. 3:26 I've seen this movie before...
The lake beach I lifeguard at always has an algae bloom, is it really that toxic?
Photosynthetic skin grafts brings John Scalzi's Old Man's War Series back to memory.
I welcome my new overlords what a glorious future.
Up next is alge "chicken" nuggets. And alge burgers.
One step closer to Dr. Reginald Bushroot from Darkwing Duck.

Waiting there time...
Villain of swimming pools, hero to science
Wait.. a lot of skincare chemists and derms say that there is no link with oxybenzone and coral reef .. so.. curious how SciHow would respond to that?
It always has, and always will.
I am truly impressed by algae. I am a bit disappointed with the lack of respect that I have hand for them.
My brain shorting out every time the host says plant.
I once saw one of those survivalist shows, and the guy was on a desert island. He used a sea sponge secretion for sunblock. He said it was extremely strong. Maybe that's a possibility?
Another product produced using algae is agar, which is used in growth media due to the fact that very few things can decompose it.
Wouldnt the bacteria/fungi interrupting algae chemical be really beneficial for plant tissue culture?
In the anime Knights of Sidonia, humans have modified thier genetics so thier skin is able to photosynthesize.
Anime is becoming real people.
This is awesome.
I'm down to be a Chimera!
*six months later, "Edward...?"
First thing that came to mind was full metal alchemist lol
Algae would certainly make better biofuels than certainly corn-based or probably even sugarcane-based biofuel, in terms of taking up much less land and not taking away from the main food supplies. The trick, obviously, would be to make it economical on a large scale!
Next to yeast, algae might be one of my favorite single-celled organisms.
I like beer and bread too, but my gf isn't so crazy about yeast.
@@squirlmy 😂🤣😂 I'm a pastry chef.
I for one welcome our new algae overlords
A more accurate title might be, "Algae Might One Day Rule The World - AGAIN."
I'm most interested in oxygen-producing grafts. For many bacteria, oxygen is toxic, so simply exposing those bacteria to oxygen is enough to keep the bacteria population down. This has obvious benefits when dealing with bodily tissues that can get infected. The presence of oxygen could help prevent infection.
Darkest green i've ever seen !-)

6:36 Every time you plant fresh food in your garden. The plant takes in nitrogen 777 to create its food from the sun through photosynthesis and it breathes in Carbon 666 and it out Oxygen 888. (While we do the opposite as carbon based lifeforms we are co-dependent upon one another so it is in our interest to care for our planet and all its diverse life) Also you may be asking. What are the numbers about? Well here is an example and you can extrapolate from there.. (666 = Carbon = 6 neutrons , 6 electrons , 6 protons) The periodic Table can teach us much

Cool
I am not surprised, algae is playing long game
Daaaang algae is looking sexier than normal
I look forward to our new algae overlords.
I thought algae is a plant-like protist.
They're more like not-animals than plant like protists. There are plants, Cyanobacteria, Dinoflagelates and they're all very different, but conveniently fit in the same category because of how similarly they operate
If youve ever owned a pool that’s gone bad. This isn’t a surprise. Haha
i can imagine people getting full bodies skin graft so they wont have to breath or maybe even eat if the algae cell over produce some kind of food source for their bodies
Algae are amazing
its ruling over my aquarium, thats for sure
How do you conquer Asia? One steppe at a time.
There is no Russian it
Photosynthetic skin sounds really cool. We could be almost like that original proto-plant organism that ate some cyanobacteria some million years ago (that might not be exactly what happened). If there was one evolutionary trait that we should adopt as humans, it's probably this one.
They already do.
Rationality rules sci show edition
"It's more epensive to process the oils extracted from algae than palms, which is why palm oil is still more enticing to producers, despite the havoc it wreaks on nature"
Yes, that is the root of the problem, isn't it? Our civilization is currently run by profit margins, not intelligence.
Why would we do anything good, when we can profit.
Stonks
Expensive not only implies it costs more money, it costs more of everything, it means producing algae oil is terribly inefficient and the resources needed to replace the palm oil today with algae oil would be more destructive than killing the jungle! (Which is unacceptable).
I for one read the labels and don't consume anything with palm oil in it.
@@fenrirgg source on it destroying more of the environment?
Considering the video said it takes up less room, and can be done anywhere this claim seems off base.
@@Somebeanwhoexists it's not being commercialy produced yet because the explanation I said. The source is open for everyone looking for information on the internet.
@@fenrirgg the internet is a big place.. some might say it just looks like you're making up stuff if you can't show to a source.
We made a chimera? I'm so hoping it didn't go down like Edward in FMA.

Tony Heller !
They've been touting algae as a cure-all since the 90s as far as I can remember, still waiting... :P
What about hair algae what is the product we can make out of it
I notice hair algae is also high in fiber
I'm surprised they didn't include shoes.
Mix biofilm with tooth paste ?
It doesn't already? Sure, it's one of the lowest life forms, but it's widespread and a lot of life depends on it.
Being eaten doesn't suggest you are 'rulling"
@@julianshepherd2038 when you out-reproduce and outlast most of the species that eat you, you're ruling.
All Hail Algae!
I am pretty sure there are already artificial Algae vats for harvesting them commercially and sustainably. So I don't see why we would not be able to harvest them in a sustainable fashion.
Because they don't produce enough of the compounds we want. If we genetically modify them to increase the amount of those substances they make, purification becomes easier and the higher yields make it less expensive per gram of the produced compounds.
