“Don’t worry it only eats algae and fungi” tell that to the algae peacefully providing another cell with food

"Our bodies, after all, are built out of the lessons that nature learned with them." that was a dope-ass line you just casually threw down at the end there my dude

"There's no mytochondria powering the cell" made me laugh

Trick for imaging things that are too thick/break when a coverslip is applied: Cut a coverslip into 4 thin glass strips (diamond knife is useful, but it goes not necessarily need to be super precise). Glue a stack of 2 glass strips on each side of a slide (these serve as spacers). Apply sample in the middle. Place intact coverslip on top (resting on top of the spacers). If your sample still gets crushed, glue on additional spacers on top of the others. This is how zebrafish embryos are imaged.

7:50 *- Yup, that's me. You're probably wondering how I ended up in this situation.*

*Pseudopodias are overrated. Wheel bearing mouth-parts are all the rage now.*

I have to say not since Carl Sagan have I enjoyed the sound of a science narrative as much as I do hearing your style and voice Hank.

"Primitive..." it's worth remembering that _everything_ we can see today has been evolving for 4 billion years or so, even the most 'primitive' organisms. It's no wonder that even the simplest organisms most similar to their ancient ancestors have developed some fascinating complexity.

The one dislike is a rotipher being slowly eaten by a heliozoan.

I love this channel, this is like something I would have watched if this was on TV when I was a kid

I have a fun story about amoebas. Back when I had my first microscope around age 12, I started to get serious about culturing protozoans. My scope was just a cheap piece of crap Tasco, but it could do protozoa just fine, so I did a lot of pond, ditch and creek water samples, cataloguing everything I could find. Ever voracious for more and more to see, I decided to experiment with culturing by first taking a sample of water and then adding broth to it and seeing what would happen over several days. My nightmares awoke fully in me after I mixed some beef bouillon to a quart jar pond water sample and leaving it loosely covered in our barn in summer. I would go out every day, make a slide from the jar and observe on site, using sunlight with the microscope's mirror for illumination. Eventually, the jar took on the smell of dirty socks. One day, I stood there in the barn, squinting to see, and noting that nothing was visibly moving nor alive. BUT, I did notice a strange sort of speckle appearance to the entire sample, and it seemed to glisten strangely. Whatever it was, it was _tiny,_ at the limits of the microscope, and seemed to be _moving._ I upped the power all the way, got the best light I could, and tried again. Carefully focusing, I finally got it, and was horror struck to note not a few, not dozens, but hundreds, perhaps thousands of tiny, tiny amoebas slowly oozing around the sample. At the time, my mom was taking college courses for her RN license, and I was constantly reading her medical books, which often included graphic photos of various diseases. In one illustration, amoebas had infected a patient's intestines, which then breached their liver, diaphraham and infected the lung as well on a path of rampant destruction. There I stood in the barn, and it all clicked hard in my head - the smell of dirty socks meant at least _something_ was getting in the air from a jar full of amoebas scarcely bigger than red blood cells, and I was breathing that something in. I did a quick sketch of what I saw, then immediately dumped the jar and vigorously washed my hands, fearing that I would die of amoebic dysentery any day, lol. I also stopped the beef broth experiments entirely, despite that they had so often provided such amazing results. Now that I have a vastly better microscope setup, I really wish I had a sample of those tiny, tiny guys. I've seen plenty of common amoebas with it, but those were definitely something more interesting.

This is a *severely* underrated channel. Brilliantly narrated and written, and who can argue against how awesome the visuals of the microcosmos are. Thank you for the fantastic content

"Our bodies, after all, are build with the lessons that nature learned with them" What a lovely sentence.

I love amoebas. They're the first thing I ever remember researching outside of school on my own volition. Thanks for taking the time to make these. I didn't even realize it was Hank narrating these until I'd seen 5 or 6 of them.

I love that the advert algorithm has no idea how to classify these videos, i keep getting adverts for biochemical lab equipment and other random similar stuff!

You lost me in the first minute when I realized that I didn't know nearly enough about brain eating amoebas. And now I know WAY TOO MUCH about brain eating amoebas. Thanks, Hank...

If there are awards for perfectly made yt video, this channel should get em for all of these series... Graphics, background music, narrative voice and dynamic...all perfect. Length of video long enough to teach you and relax you, short enough not to put you to sleep. Respect.

Amoeba have a "movement by flow" that I find hard to understand, it's fascinating to watch.

Hey ive been a fan of this channel for a while and i just wanted to say keep it up! I love your work!

8:30 you just gave me an idea for my thesis

This series is amazing. A realm of science I never knew I loved.

I think the reason I absolutely love this channel is (other than the incredibly soothing voice and music) is the fact that they are more than willing to admit what we don’t know, even asking people to go figure out stuff, and because of this, because they show all the cool things we know as well as the countless multitude of stuff still to discover. It just fills me with curiosity and keeps me hooked. Absolutely love this channel, never change.

8:17 Might it be better to ask "if they are better off" without mitochondria? Evolution tends to get better, but that's a trend, not a constant :) Fascinating hypothesis, which is probably right, however!

Thank you for taking me on this journey, ever since I subscribed I have not been able to satiate my craving for your videos. I can honestly say they are the most interesting and relaxing videos that come into my feed. I just wish I could support you with a donation, for now however, a simple share must suffice.

I wish your videos were longer! I absolutely love the structure and the narration is top notch! I would like to see some longer videos on certain things. I don't have anything specific in mind and I'm not suggesting every video be long. Perhaps one here or there on really interesting topics. Your production is amazing and I would love more in depth coverage.

"Our bodies, after all, are built out of the lessons that nature learned with them." Such a powerful statement!!!!

This is the most relaxing channel on UKposts

The tone, pace, phrasing, and everything else about the narration is luxurious. The videography is mesmerizing. Thank you!

I really love that you guys use Andrew's work as the soothing atmosphere for these videos. It adds a whole new degree to these videos that I never thought necessary until I heard it. There should be more ambient science videos like these. They're very nice to watch after coming home from work.

Brilliant channel. Have loved every single vid. Thank you so much. Excellent soundtracks and Hank is mellow, not shouty. Thank you James for such a visually delicious feast.

I must say that, the content, writing, sound design keeps improving exponentially on this channel! Please never stop!

So glad that this channel is here. It's soothing, fascinating, groovy, all at once.

To avoid crushing samples, buy some of those glass spacer rings or rectangles which are made for protecting fragile microscopic organisms. Alternatively, a ring of lacquer or gum can be used: Paint the ring, allow it to become almost dry, add the sample, and then the cover slip.

Funnily enough these so-called Brain-Eating "Amoebas" are not an Amoeba species

I would love the Journey to the Microcosmos to come up with a recommended reading list. Like having a book club centered on microbiology.

Pelomyxa losing mitochondria after previously having it is now going to haunt me in my dreams if I don’t research this topic. This is mind-blowing.

That blue background with the green cells is sooo relaxing, almost hipnotic.

Could you do an episode on Gastrotrichs? I recently saw one in some pond water and it was an amazing find. I took pictures under high power, and they turned out really well.

Always look forward to Mondays and Tuesdays for this it's the best thing ever

I love this channel, the journeys are educative and relaxing at the same time. Just a little idea: have you considered putting a bar scale into the corner, in addition to magnification? Maybe it would help to imagine how big the cells are, more than the magnification (and it would be independent of screen resolution). Anyway thanks a lot, continue great work! :)

This is without question one of the most interesting series on this platform; that deserves a full length documentary series.

This has to be the cutest channel. And Hank's sleepy voice hits just right.

This channel is like a fresh breeze blowing through the desolate and shallow landscape of UKposts. I am waiting with utter excitement for the next episode. The Microcosmos really is of a rare beauty. Thanks fir sharing it with us.

I love this channel. It is an escape into wonder, and and invitation to ponder at the complexity of our biological world - even at such small scales. These are our building blocks, offshoots of our very early progenitors. The most incredible thing I learned in Neuroscience was that early human fetus developments look like transitioning through other, ancestral species to mankind. It's humbling and incredibly informative at the same time.

Heh, I work in a lab that tests for N. fowleri in drinking water! Nice to see this mentioned :)

Classy af Hank. Keep it up.

I just discovered this channel, and I'm instantly a subscriber! Excellent content! Also, if I ever need a voice actor for a cat, this narrator is my first choice.

Im loving this series so much. Thank you for it.

one of your best episodes especially with that intro about the literary references to amoeba. So good man

The amount of subs you have doesnt do justice to the quality of your content. Amazing guys.

I have a video request. I want you to talk about the micro marvel that is the bacterial flagellum. It is not connected to the bacteria and still lives. My friend is into speculative biology and has designed a creature with helicopter-like blades on its serpentine body. Not attached, like the flagellum. She looked up the issues and believes she has solutions to a few. To make them spin, this creature creates electricity. Lubrication liquids greatly cut down on friction. And the spinny parts reconnect to the rest of the body periodically so they can be resupplied.

Keep up the Great work Hank and the Team!

Your voice is soothing but it doesn't put me to sleep and keep me spiked and interested I love it!

I like watching this sort of stuff while i take a nap. I get some crazy dreams sometimes. Thanks, have fun and stay safe.

The tone and cadence of your voice is perfect for narrating ....peace out

Compared to Hank's usual enthusiasm he seems sedated in these ones :) . And,,,, this is an awesome channel.

Wow, I love this channel so much! I've always wondered what amoebas are exactly, and their behaviors and what they eat exesdra.

I just had a science class where we observed pond water. I SAW SO MUCH

Beautiful work. Ty

It's so pleasantly weird when the video zooms out, and you simultaneously lose focus on what you were looking at and immediately see something else coming into focus you didn't notice before.

Tardigrades and hydras and stentors! Oh my!

This channel is surprisingly very effective to help me sleep. And I can learn something at the same time! (at least before I fell asleep)

This channel makes Mondays bearable!

Super fascinating, thanks for the info.

This is beautifull in so many ways. Thanks for sharing

This series have made me understand how cancer occurs and why. I am not a medical expert but I have read a lot about DNA, life, simply put. Your effort is greatly appreciated. You have enlightened me in the greatest way possible. Thank you guys and your sponsors of course!

I enjoy your movies, narration and music. I also like the background research you do and I hope that your movies inspire more interest in microscopy and the microuniverse.

I love this channel! Regards from Italy

the various colored backgrounds are very nice, offer variety, and give the eyes a break from the stark white. as such i highly encourage their use. thank you all for this wonderful and amazing series.

Great video, this microbiology content is top-notch.

I thoroughly enjoy your videos.

Gave myself a high five when I knew it was an Ameoba before it came up in the corner. I'm finding these videos TOO full of info in many ways. Too many new names and then classifications are a bit overwhelming at times and I feel its hindering my learning. I hope that eventually this channel will have individual creature videos so we can see just one species and get to know that better. If this doesn't happen however I am more than happy to take what I can get because this is THE best channel I've seen for a loooong time.

my first encounter with the concept of an amoeba was from a babymouse comic that i got from the school library. that was one of my favorites. i remember that book was colored partially in green when babymouse comics usually only used pink.

Great video as always...

Best episode yet!

You found the perfect music for this channel. :)

I like to watch your videos before sleeping. Its amazing to explore the microscopic world

You describe music so well! 😉

always enjoy the content here, Could you please do a series of video's surrounding the crispr process. with the wave of home made "medication" being produced and the genetics traits that people are trying to move from one species to another, it would be interesting to find out how effective it currently is. Id be interested to find out weather the gene that causes the development of wings could be transferred over to humans and how long it could realistically take to see an effect.

Love the channel so much! So I hate to quibble, but when a word I know amid the tens of thousands I don't is mispronounced I feel I must cry out, or clack out anyway. I knew Marc Weinstein of Amoebe Music when he was a manager at a SF record shop down the street from the one I managed at the time. His name is pronounced Wine-STINE. The syllables rhyme. Don't know why this German syllable (meaning "stone") is so often pronounced wrong. We say Franken-Stine, not Steen. We call it a Stine of beer. Google a video interview with Marc and you'll hear him say it correctly. Afterward, keep making more of these incredible videos. They're gorgeous and fascinating and the music is perfect, Mr. Huang.

I'm so chilled out after watching this.

"In terms of size, amoebas can range from microns to centimetres" Wait WHAT

I love how casual talk about brain eating creatures

I love the final message, so true.

I think the main point here is that even tiny life is immensely more complex than most folks give it credit for having. Great video, one of my faves, so far.

This is legit the most underrated UKposts channel?? Like I’d expect the channel to have 2 million subs 😳

Hmmm, interesting. Wouldn't want to be one though.

Yay, a new video! With an epic title! Thx :)

This is an amazing channel

BEST YT CHANNEL OUT THERE 👏🏼👏🏼👏🏼

I almost spit out my soup when Amoeba Records came up because I was already thinking about that store when I clicked on the video. I've always felt like amoebas are the cool kids of the microscopic realm for that reason hahaha

7:53 just chilling and suddenly bolts out of there 😄

this is the most satisfying series ive ever seen

Hank's voice is smooth as butter in this video

This channel voices a poetry of science and it is beautiful

Hank Green is like scientific Mr. Rogers- so calming and friendly, but could explain anything to you.

Very fitting narration voice. Tops.

An episode dedicated to eating and digesting would be amazing. I'd love to see the stages of digestion inside of a food vacuole.

His voice sounds so calming- imma fall asleep ;u;

I had no idea the commentator/writer for this show was Hank Green from Scishow...
