@Richard Joyce That's the square cube law. Ants being able to lift five times their body weight sounds impressive until you realize that if humans were their size we could lift a lot more than that. We need so much muscle because we're big.
The little Stentor home shopping at the end is so adorable to me! How in the world do I actually manage to look at these small tiny organisms and actually find them cute? I don't know, but I love it! Also, as a brain damaged person (TBI), this subject/video is particularly fascinating to me. I feel like i'm on auto pilot sometimes without realizing that I switched over and I don't even notice what I'm doing while I'm doing it. I guess maybe I'm not alone :D
A possible answer to why you find them cute might be an abstract association with cultural forms of art, like cartoons. Unconsciously (or sub-consciously) you enjoy and find them cute because they resemble relatable aspects of living organisms that you find cute, or perhaps fictional artwork that you also find cute. It is weird how a brain can co-relate a cute living organism with an abstract piece of art and then further make connections to these tiny creatures. At least according to me, this seems to be the simplest answer my limited knowledge can come up with. Also, you are definitely not alone about the autopilot bit! Nature seems to control even the most self-aware organisms, for example, the simple adrenaline rush in a fight or flight response, your TBI in fact brings you closer to nature and every other living organism! I hope you have fun at every moment, though!
Steph P. What you described sounds pretty normal to me. I don’t think I’ve ever met anyone who doesn’t space out. Must be a lot of parents lying about dropping their babies.🤷♂️😂
This has to be one of the most fascinating among all of these wonderful videos. All of my life I have been intrigued by single cells doing what many people thought that ONLY humans could do. It seems infinitely more difficult to understand how humans think and decide. But here, reduced to the "simplest" unit of life, single cells seem to do everything that we do except talk and play chess. This seems so profound, mysterious, awesome. Now I'm a senior citizen at risk of being terminated by something that probably isn't even alive. I do hope that I will live long enough to learn more about how single cells can interact with the universe in such a complex ways. Keep up the good work guys.
It’s because life is the one at the helm. Not us with our brains . I think our brains just give us the silly idea that we are the ones doing everything . 😆
The way the bit at 6:10 with the two stentors juggling a paramecium was filmed is so beautiful and detailed compared to the rest. The depth it provides lets me visualize and understand how these creatures look so much more than the regular 2d slides. I wish more of these videos were done like that.
*Sometimes me and my paramecium buds would have a carmine drinking contest at my fellow Stentor's pad. Gnarly stuff let me tell you. After a few drinks in you'll feel so wasted you'd think your mastax was on fire from all the burning.*
You guys are absolutely blowing my mind with these videos I really appreciate it. It's incredible that even at the microscopic level there is predator and prey. It seems like the African Savanna, so much variation. Tiny plant life photosynthesising, animals eating the plants, the predators that eat them, and rudimentary eyes to perceive light and circadian rhythms. It looks as if life just grew more complex and larger, but the evolutionary basis of finding food and reproduction have remained the same. There must be biological laws to life its self, similar to the laws of physics.
As a cell biologist this is absolutely fascinating. These single celled organisms appear to be making "decisions" but they're really just spontaneously reacting to the environment through various receptors and the subsequent changes in protein organization (shifting the cytoskeleton to change shape), protein function (like waving cilia) as well as transcription and translation of new proteins to change what the cell is doing at any given time.
These videos are mesmerizing - hypnotic even. A ten minute video seems to pass in less than a minute. I’m always disappointed there isn’t more. I can’t say that about any other video channel..

I love that even though you could hurt or kill the organisms for the sake of curiosity and science, but you don't-- ethics are just as important as curiosity and experimentation. You have always been able to demonstrate and explain what you're talking about without doing permanent damage.
This is fascinating! There seem to be many parallels between microorganisms and the way simple programs/robots work. But i never thought of how these microorganisms are even able to do these simple tasks and especially loved the part that even different specimen have different behaviour hierarchies.
I don't know why, but the Stentor's decision-making process is so damn relatable that I think it is my new favorite protist. I don't know how it made the decisions it made, but that it made decisions I think I might have made in its place makes it easy to sympathize with its plight.
"Moments ago, you made a decision to click on this video." >me, who clicked this hours ago and only tabbed over after gaming a bunch Yeah...moments ago.
Thing is, single cells seem to show some capability of being computationally complete. And that goes for nerve cells too. So the brain as an organ is actually an entire computational network processing information and not just a single computer. So think of this kind of thing as being akin to scaling parallel processing, and how that affects the ability to deal with information. Single cells of course may not be able to compute much in terms of stimulus vs. response, but perhaps they're able to respond a lot faster since thy don't have to do a poll and come to a consensus for their decision like the brain of some multi-cellular organism.
"Your body had to go through very complex processes for you to make and execute your decision" Me: Okay, the thought of the complexity of my thought just made me exhausted.
Mind = blown. Unicellular organisms have preferences, and respond to stimuli in a sophisticated manner, in a way even *learning*. Wtf. No idea they could do any of these things. I'm in absolute awe.
basically the complexity of any videogame (except minecraft) has about the same interactome as the microcosmos: go somewhere, do something, eat, avoid and so on. to think a single celled organism would be smart enough for those basic concepts.
How prescient of you to know!! my steps to get to this video, which I did select, began with selecting video earlier, then two newer, until I came here. My brain is pretty cool! Great introduction to this vlog episode!!
Hank, this vid is part of my routine, usually before bed on a work night because I learn things and your narration is quite soothing. Thank you and keep up the good work.
I love the sheer poetry in these videos. As someone who doesn't like inspirational quotes, such videos like this give me some cool quotes to practice my fugly handwriting.
5:53 I had to rewind this entire clip section because I was too busy watching the Paramecium narrowly avoid death as it repeatedly ping ponged back and forth between the two Stentors. I was literally clenching my abs and like, holding my breath the way you sometimes do playing a video game or during an action scene in a movie rooting for the good guy to make the jump to the roof lol. Then at 6:27 I was like oh wait what were you saying Hank?
"Contract like nobody's poking you. Inspect like you're never moving away. Eat like the next decision's never coming." -- Mark Twain, Stentorian writer
5:43... the look like little mini swimming tropical islands all bumping around on the ocean lol ..just the way they look like statalite images of lake and forrest.
What I want to know is HOW they (e.g. a paramecium) make these decisions? How do the cilia coordinate to go in one particular direction based on where the thing WANTS to go. How does it know it is being poked? Is there something equivalent to a tiny brain and nervous system going on in that chemical soup of the single cell? Do each cilia 'decide' what to do independently and the combination results in coordinated movement? Just how does this work on such a small scale? Understanding this is vital to understanding consciousness, I think. When/how does a chemical reaction become a decision?
"Is there something equivalent to a tiny brain and nervous system going on in that chemical soup of the single cell?" Brains and nervous systems aren't magic. They are just specialized cells doing electrochemical signaling between each other that ultimately work just like any other cells. They just network the information processing power of many cells. It's like asking "how did 1950s transistor computers work, did they have tiny microprocessors in their transistors"?
If I were to have to engineer such behaviour into a simply system like a uni-cellular organism then I would: Design subsets of reactions. And with actions I mean the most minute effects such as a single silia rotating clockwise or anti-clockwise. Each subset when active, being a collection of actions which together lead to a certain mode of behaviour. Then I'd make all the subsets sensitive to the concentration of a particular chemical signal carrier. The concentration of sensitivity dictating the order in which these behavioural subsets activate in. Each subset being active only while the concentration of the chemical signal carrier is within a specific band. The default behavioural subset being active only while none, or very little, of the chemical signal carry is present. The final behavioural subset only activating once a very high concentration of the chemical signal carrier is present. Then I would simply let each instance of a particular stimulus (mechanical irritation in this case) release incremental amounts of said chemical signal carrier. Top it off with a mechanism constantly scrubbing the chemical signal carrier present within the cell. Possibly even by metabolising it into another substance that can serve as a signal carrier for another range of behavioural subsets to allow for for a series of behaviours leading to a climax (maybe a flight behaviour), and then to another set of behaviours to recover back to the default behaviour (settling down and getting on with things again maybe). A truly wide range of behaviours could evolve through subsets being sensitive to various concentration bands and ratios of both the postulated chemical signal carriers - Via mutation of the signal carrier sensitivity couple with natural selection. Et Viola.
it really causes reflection on what it means to be conscious and what consciousness is. Many will say "well it's in the brain" but something without a brain or even a nervous system... is aware. it is conscious.
Intellect without a brain is the most fascinating curiosity within my wondrous repertoire so I adore any/all pertinent information.. indeed, Journey to the Microcosmos is a treasured pleasure but I have a genuine question (re 0:30): What the heck is a comfortable position?. how is such possible when built on bone, made of meat, and frilled within itchy skin? 🤷♂️
You should read “the price of altruism” along the similar lines, the author follows the work and tragic story of George Price who set out to disprove his own theory on the statistical basis of altruism. He is consumed by the idea that kindness cannot possibly be predetermined, he was unable to prove himself wrong and eventually committed suicide.
I clicked this by accident, then turned off my phone because I had to do something. When I came back, I was pleasantly surprised and decided to watch the video. No real choice in selecting the video, just random.
It's crazy to think that behaviours at the lowest levels are directed purely through electromagnetic forces between atoms and molecules. How such behavioural patterns come to be is a fascinating thing to ponder. From chemical soup emerges. Emerges what, conciousness? Or was conciousness already there to begin with?
10 to 20% of the genome of organisms code for genes which order protein production. The other 80 to 90% is an "operating system" which is a massively parallel groupings of AND, OR, and NOR gates which serve to create rapid "decisions" which permit survival. We humans simply fail to grasp the utterly fantastic constant information processing , the dance of rapid protein cascades affecting cytoskeleton shape and ciliary motion (even in the simplest flagellated bacterium) And, the dance of RNA with DNA/histones for gene promotion and silencing is so utterly incredible, only tiny portions cannot be grasped.
Where can I listen to more of the soundtrack used in these videos? I looked through Andrew Huang's channel and Spotify, but I couldn't find the same music as used here.
Piece of hair helped me a lot to understand size of these creatures finally, because I couldn't visualize how big or small with magnification level or micron measures.

I was looking for a 10 hour version of some music video, but then I saw this and thought: "Let's procrastinate!"
Intellect without a brain is the most fascinating curiosity within my wondrous repertoire so I adore any/all pertinent information.. indeed, Journey to the Microcosmos is a treasured pleasure but I have a genuine question (re 0:30):
What the heck is a comfortable position?. how is such possible when built on bone, made of meat, and frilled within itchy skin? 🤷♂️
*nobody* :
*scientists* : "lets poke some microorganisms!"
Of course I know him, he's me
These creatures are much more sensible than humans
*They didn't show footage of me being poked. It's because I required them to take me out to dinner first!*
Good job Rotifer, way to stick to your dating ethics :D
Some things have to stay private...
It's simple, i see nature documentaries or cat videos, i click.
The parameciums are so green and sparkly!
Yay a video! and thanks for assuming I easily performed these tasks.
7:35 favourite part... *stab stab stab*
Do you know of a non-reproduction copy of the Behavior of the Lower Organisms? Amazon at least only has the artifact reproduction reprints
nice. I love this channel so much
You should read “the price of altruism” along the similar lines, the author follows the work and tragic story of George Price who set out to disprove his own theory on the statistical basis of altruism. He is consumed by the idea that kindness cannot possibly be predetermined, he was unable to prove himself wrong and eventually committed suicide.
Your videos are my favorite biological rabbit hole to go down. These vids are like potato chips: just one is not possible
I clicked this by accident, then turned off my phone because I had to do something. When I came back, I was pleasantly surprised and decided to watch the video. No real choice in selecting the video, just random.
It's crazy to think that behaviours at the lowest levels are directed purely through electromagnetic forces between atoms and molecules. How such behavioural patterns come to be is a fascinating thing to ponder. From chemical soup emerges. Emerges what, conciousness? Or was conciousness already there to begin with?
10 to 20% of the genome of organisms code for genes which order protein production.
The other 80 to 90% is an "operating system" which is a massively parallel groupings of AND, OR, and NOR gates which serve to create rapid "decisions" which permit survival. We humans simply fail to grasp the utterly fantastic constant information processing , the dance of rapid protein cascades affecting cytoskeleton shape and ciliary motion (even in the simplest flagellated bacterium)
And, the dance of RNA with DNA/histones for gene promotion and silencing is so utterly incredible, only tiny portions cannot be grasped.
Amazing video guys! Any chance you guys can show Symbiosis in Microcosmos?
What's the little tube at the bottom of the screen @2:57 with the helical structure? is that DNA?
Lovely video. Glad the Stentor got a happy new home at the end, haha! But if poking it to see what happens isn't science, I dunno what is!
Where can I listen to more of the soundtrack used in these videos? I looked through Andrew Huang's channel and Spotify, but I couldn't find the same music as used here.
Piece of hair helped me a lot to understand size of these creatures finally, because I couldn't visualize how big or small with magnification level or micron measures.
Bottom right
@@profpuffofficial2 I know that already, thank you. What I'm saying, it is hard to visualize size of a 100 micron creature without a piece of hair next to it.
That last slide of white tendrils and the green stentor was mesmerizing!
Oooooh this is something I was super curious about. Yuussss
are those things flat (2D) or do they have significant thickness?
Wow this channel is purely awesome! Have you thought of doing translations in other languages to raise awareness about the microcosmos?
Great 👍 information. Many thanks 🙏
