@Green Ghouls You know that's what I thought, but I am now hazy about the "Under microscope" world after so many many decades away from my old zoology classes. Thanks for the verification! :-)
Imagine being considered a "celebrity" among beings of unimaginable size and intelligence, who think of you as a cute tiny immortal being. Mind bending to say the least.
@Stellvia Heonheim He is a very laid-back (calm) painter on US television who showed people how to paint on a show called "The Joy Of Painting". It's become an overused cliché to say anyone who is calm and has a measured delivery is "the Bob Ross of [whatever they do]".
I showed this to my mom last night while we were in the ER (she broke her wrist). She was pretty upset that she hurt herself and couldn't stop panicking until I showed her this video. She's a first grade science teacher and absolutely ADORES tardigrades, and this video was super captivating for her, to the point that she was able to calm down and go back feeling less anxious. Thank you so much for making something both informative and fascinating!
My elementary science teacher used to call me "tardigrade" every time I couldn't figure something out. I would ask her what it meant, and she would just snicker and said it was only her little joke. That always made me feel kind of stupid.
I was looking under a microscope in a Cell Biology lab last year, and I was trying to observe cytoplasmic streaming in a sprig of Chara. I didn’t see cytoplasmic streaming that day, what I did see was a tardigrade, eating the Chara cells I was supposed to be studying. That’s the moment I realized that I chose the right major. Thank you Tardigrades!
I love this. This is what I hope everyone who studies science experiences in their respective interests. Mine is physics, but I totally understand your happiness with your choice in major
Humphihzly yeah, id have never known if i hadn’t read the description. I like this Hank though, the narration supports the trippy space/ocean vibe of the video.
Ya in this type of video, it's great but most RU-vid videos I watch at x1.5 or x2. These people take so long to get to the damn point. But these micro vids, it works very well to keep it relaxed.
It boggles my mind as a nurse that they are born with a set number of cells, and for them to grow the cells get bigger It feels like the rules of biology somehow got turned upside-down 🙃🤣
I mean, calling their eye and eye is being generous with the definition. It's like calling a jellyfish brain a brain and comparing it to a human brain.
@@aydinsha indeed. Those two cell might have some visual sensory to the environment when it comes to perceiving light, it's probably the most bare minimum. Their "vision" probably consists of "is there light where I'm facing?" If there isn't, it tells them there's an object immediately in front of them.
one of my early memories is my dad taking me to a pond to collect these, and making up slides to view them under a microscope. He used to also sneak thermos-flasks full of liquid-nitrogen home from work to play with. good times :)
@@ASMRChemistry sadly not... before the internet so I don't think it was well known. He's a retired immunologist, so we've had a lot of good chats over the last year :) (he's also really into his calligraphy! small world) *edit, you just got a new subscriber.
If I had to make a guess, I'd probably say it's full of light sensing structures that only really tell the tardigrade about the directionality and intensity of light. Small proteins that send signals to other parts of the cell, or directly to the rest of the organism, whenever they are excited by light rays through some sort of chemical change
At one point in our evolution we probably had one single photoreceptor to sense light, as it is advantageous to know your orientation to the sun. The better question would be, how do our eyes work with billions of cells?
There is a great TED-ED video explaining the evolution of the eye. It explains the single cell light sensor eye thing - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qrKZBh8BL_U.html
How did I not know they had eyes, it’s sooooo cute! Edit: I am very well aware that they are not actually eyes, but “How did I not know some of them have two photosensitive cells that resemble eyes...” just doesn’t have the same ring to it.
@@journeytomicro thank you for this channel. I have a newborn son, will watch this entire series with him again when he's older. This is like cosmos by Carl Sagan.
Like they said they're not eyes as they're two single celled light receptors, they're eye-like, but certainly not eyes. As they said eyes is an organ, in order for something to be an organ it must be made up of tissue and tissue is made up of multiple cells not just one.
I liked this video and I especially liked it when it tried to find examples of tardigrades dying but in both cases they just refused to die and injured one of their predators severely instead
Still not over Hank's soft voice, he's usually so enthusiastic and all over the place with joy and amazement ! But with a bit of getting used to, I love it as well !
I’m a big fan of this project! Despite I speak a little english (I’m from México) I hope this could be translated to many languages, more people around the world need to enjoy this
I love everything about this show: The mesmerizing things we get to see and discover. The interesting information we get to learn. The inspiring script writing. Hank's splendid and soothing storytelling. The calming but sometimes funky music. All blended together producing a gem of a show. This is literally since and art combined which is just a beautiful thing to exist 💚💙 Also: Tardigrades appear to be one route of evolution hitting it's climax.
I love Hank on the Sci Show. I did not realize this channel was on his resume as well, but recognized his voice instantly. But here, he is delivering awesome ASMR. His soft, quiet delivery is so relaxing. Great stuff. Never stop.
I'd love a channel that treats these like pets, chronicles their lil adventures and stuff Wanna see them hunt, be hunted, mate, explore, vibe, for hours
Between my back injury, potty training twins, and very sick family members, this channel brings me a few minutes of pure enjoyment. Which I desperately need. Thank you for all that you do Hank. I love your content and appreciate you.
Hank, I love all your channels. I just want to know how many Valium you need before shooting these? Seriously though, yet another awesome channel with great content!!
Please tell us about the variety of Ciliophora. This group is so interesting but nobody could tell a complex information about their diversity: about the biggest and smallest, who swim and who walk, who eat bacteria and who feeds by symbiotic algae... It could be amazing!!!
Two things that amazes the most about microbiology: huge unicelular organisms and tiny multicelular organisms. Like, how do they even exists? It's sooo counter-intuitive to me how can there be a multicelular organism with digestive tract and nervous system which is smaller than a single cell.
Well, thats not entirely true. There is a limit to cell size and although technically you could say an ostrich egg is a single egg, it houses the actual living being, which is multicellular, the embryo. It is not an alive, working cell in that regard anymore, just a container doing its duty. Imagine different bird sizes, from hummingbird to osprey. Quite the size difference. Now apply the same to cells and imagine both being single celled creatures.
Three years back I saw Tardigrades for the first time in a bio lab. I spent way too much time during the 1hr50min lab period infatuated by them. Gotta love biology!!
@@3AMJH Face mites do indeed not poop. They just keep eating until they die... at which point all their waste explodes from their bodies... on your face.
Narrator: And just in case you wanted to see it again... Me: Yay another close up of its cute face! *Tardigrade pooping* Me: *OH* ... kay that works too.
@@thedeathcake Immortal vs Invulnerable: "Will live forever if not harmed" vs "Too tough to be harmed". They can be eaten, and he said they don't *prefer* extreme conditions (like extremophiles). Which means if you boil or acidify or salt them faster than they can go into cryptobiosis, they'll die. They're still tough little critters tho. I want to be able to dry myself out for future scientists to revive me!
This channel is intellectually challenging me in ways I’ve never identified before and I love it. Thank you for teaching us philosophies about our favorite little “immortal” friend
Suggestion: Rather than showing just the magnification, I think it would be really nice to show a little distance legend. This would both be more accurate (screen-sizes vary so magnification doesn't make sense here), and easier to understand the real scale. EXAMPLE: 200x _____________________________________ 300μm
I fell so in love with these precious little creatures when I first saw them on a microcosmos video on You Tube, that I bought a Tee with a picture of one. Their abilities are beyond amazing for such tiny creatures. 💖🥰
You choose to linger more on the edits, which is imo a great creative decision. It feels very relaxing and just feels right to present life in microcosmos.
This is perhaps the most humane explainer I have seen regarding these curiously endearing creatures. I find the narrator's voice to be greatly comforting and eminently trustworthy. What a worthwhile channel this is! Many thanks to the creators for sharing with us.
Oh my goodness, tardigrades are so tiny and adorable... those eye spots ❤ I'm loving this channel. So interesting!! And between the narration and background music, it's also quite soothing 😊
Slimes are powerful beings. We are just lucky the largest only gets to be about 100 grams or so, if feed and taken care of. Could you imagine an actual 70kg slime. It'd be either d&d, Dragon Quest, or we'd better hope they're as gentle as Rimuru.
How do the single-cell "eyes" help the moss piglet? What are they looking at? They can't form an image because there is no lens, it's just a photoreceptor. Are they color sensitive, can they head towards green stuff? Maybe to use it to figure out where the "ground" is. But do they need to navigate places in their little world? I feel like I know less the more I learn?
They must just be light sensing organs using specialized proteins, they can't see where there prey is but if they know where light is they can probably figure where to move to.
You guys are so awesome for giving out respect to the little fellas toward the end of your video! Great documentary thank you! It’s amazing they even have little brains.
I really love your voice bud, smooth not too much, submit and calm but not monotone not boring, and super personable. A notable honest and authentic delivery my friend... Real neat video, incredibly cute bears! : D
