This has quickly become my favorite series, always a great way to start the week.
I agree entirely. Microbiology is riveting.
Absolutely agree!
Yes. This is the best channel.
Every night i watch this!!!
I really agree with you - sometimes I save it, if I am really tired or busy on Monday night I'll keep it as a treat for myself on Tuesday. I wish these guys would make a series on viruses, get James an electron microscope, I am studying virology right now and I feel like if Hank explained the big picture to me that all the little stuff would go a lot easier.

"Look at them, WANTING!" - Hank Green 2019
That is actually big question for me. Why stuff WANTS?
Like i the end molecules arranged themselves in a way that they WANT more atoms.
Yay, I was not the only one.
They want because those which did not stoped existing
@@anterprites That is too general answer. It still does not explain why those first of "half alive" WANTED to stay in that state and to make more of themselves instead of going to some dead state and exist as molecules.
@@marisduhtiks7835 yeah, as a Philosophycal question it's really interesting, but at a mechanical level it's the trivial "things that did not replicate no longer exist".
The interesting question is that when we can know that we want, how do we deal with that?
I find it particularly interesting that it's so popular to say that there's virtue in not wanting, going all the way to the extreme of some people living in preparation of dying:

My daily dose of microbiology. Grab a seat.
of course the singular of cilia is cilium. if it wasn't, it would be cili
You're being supercilious.
BOOOOOO get off the stage
GTFOutta here dad
YESSSSS
@@petergray2712, Don't be cili. What he said makes perfect sense. ☺
“Look at them wanting” is such a comical and beautiful way of observing life. That really made me smile. Loving the series so far!
Layman: primordial soup
Hank: soup that wants
Nope, the primordial soup had no life in it (it's also known as the "prebiotic soup"), Hank was talking about contemporary soup life. Which is an excellent name for a band :D
Piñata Oblongata, My bad, I got the names of the two periods mixed up. Thank you for correcting me. I wanted to say Single Cell Soup
😅
The bacterial flagellum is quite different from the eukaryotic flagellum, not just in structure but in how it’s used. Eukaryotes have a flappy flagellum, like a tail. It propels them.
Prokaryotes are so tiny, that at their scale, swimming is impossible. The bacterial flagellum is a rigid spiral with a rotary motor protein structure at its base. When it rotates one way, the bacterium tumbles around, the closest it can get to swimming at that scale. When it rotates the other way, it corkscrews through the water molecules. When a bacterium “runs” the flagellum is in the front, like a teeny, tiny drill!
What I find most fascinating about bacterial flagella is both the difference in how physics works at that scale and the fantastic protein motor that drives it! It’s a literal rotary motor... on a living thing!
It's not a rotary engine (or Wankel engine), but it is the only biological axle and shaft ;) (just being pedantic)
That motor! Thank you for this correction...yes, not flappy....like a corkscrew spinning through sludge!
Piñata Oblongata, it has an axle that passes through the cell wall and membrane, but it is driven by a ring of motor proteins just inside the cell. We’re both right!
@@evilsharkey8954 Alright, I'll go with that :D
@@PinataOblongata, the bacterial "biological axle and shaft" is, in fact, rotated by a molecular 'motor'. You can do an image search of 'bacterial flagellum' to see a representation of it.
I love this channel... I get to hear interesting things about Protozoa while feeling really chill.
This is the sort of stuff I wish we dived into more when I took biology.
And then you would have to take a test on it.
There's just too many words.
@@harrysvensson2610 Tests kill chill.
I love how Hank's calm voice really resembles to those magnificent documentaries narrated by David Attenborough, I see a future there Hank
It would be nice if scale bars would be added to the clips! It would help develop a sense of scale about the micrcosmos over time.
@k1w1 the magnification factor hard to grasp, a scale bar (i.e. a bar with "1 mm" or other) would help a lot
what a great idea
Yes, yes, this is beautiful stuff, please make it even better. A piece of hair, a mm scale, a half mm scale, or a anything that would make it easier to "scale" these little pets.
Seconded
i'm sorry but a banana would'nt fit in the frame
Been on this site for near a decade and already in my Top 5 favorite subs.

"These little folks..."
I love this channel.
I work with cells in a lab and call them "little guys" all the time 😁. Or something ruder if theyre not doing what I'd like them to. You get kinda protective 😂.
I can't tell if this is poetry, date night with Hank, or what, but I like it. This is like "Hank, After Dark."
He would make an excellent beat poet.
'Hank, after dark' I love it! lol
You too? [looks at other comments . okaaayyy] Yes, this is the super chill version of Hank; and 'Hank, After Dark' really, really describes the vocal tunings of this series well. Nice catch.
(Dropping this here because I know that Hank and the other producers like to correct things in their videos)
4:41 Pseudopodia is from Greek. Ps is a Greek-only letter, and although a is a common plural noun ending in both Greek and Latin, it is more likely Greek due to the i as well as the fact that the other part of the word is also Greek.
Both pseudo and podia are Greek, you are correct. "Pseudo" means fake and "podia" means foot - like in octopus/octopodes.
Greek,along with the other classical language,Latin,are widely used in scientific nomenclature.They,ve both been used in Scientific fields since the 16th,and 17thCenturies,friends.
@@derlinclaire1778 This is about the strongest contrast between well spoken words and wildly incorrect punctuation I have even seen in a sentence.
Are you channeling your inner Zefrank here Hank? Very relaxing. Love the narration style
YOU
Just wondering, can medical technologists send you videos of parasites?
if so, can we?
Does this make anyone else miss playing spore? Lmao
Spore,is that some kind of Video Game perhaps?Don,t know if I ever heard of it,my friend.Anyway,best wishes,Kudos,and Happy Labor Day,and God bless you.
@@derlinclaire1778 ಠ_ಠ
Actually this series inspired me to make something like the cell stage from spore, but more scientific accurate :D I'm not only a programmer, but also a micro biologist and it absolutly fits my favourite interests :D Maybe I'll upload some first ingame footage, when I reached a point where you can actually play the game/simulation
@@TMtheScratcher This sounds interesting. Do share when you have something working.
@@mikejg101 I will! However, I am also busy with my Master Thesis and some other stuff, so do not expect anything in the next few months
already my favorite channel on youtube, keep it up fellas.
"The soup that wants" That got me thinking... we are basically a giant self aware chemical reaction.
You have a whole ecosystem inside of you that has never existed outside of your body
I feel like I'm getting a science and philosophy lesson, as well as a spiritual experience, in every video. Keep up the great work guys!
Thank you for this, I've been finding Microbiology interesting but have no idea where to start.
Not sure if it helps. Chemistry can be a good starting point.
The only thing I know is that you shouldn't start in school.
@@TheFox517 Where should you start? I've been thinking of majoring in it and then mastering in something like virology or bacteriology
School, or if older, adult education is a great place to start. Only reason I suggest chemistry is because everything is made of chemicals. If it has mass it’s a chemical. If it is more then one. Type of chemical. It’s a chemical compound, such as water, or table salt. Life it self is simply a self replicating chemical reactions. Consuming and absorbing other chemicals to keep existing.
Doing research on cellular biology helps a lot when trying to understand the world of microbiology. Knowing how all the individual organelles work at a molecular level really helps you to understand how all the components of a cell work together to create what we call life. Some basic chemistry knowledge helps a lot, too.
Hank: Sporozoa move in a very weird, limited way
Us: How?
Hank:
I can't always follow the jargon or the explanations, but these visuals, are STUNNING! It's like art! It really amazes me and makes me happy just to look at it! Thank you for sharing them :)
(4:16 one celled organism clearly has the ZOOMIES hahaha)
Honestly one of the best TH-cam channels. Such interesting videos, great visuals, and super smart people making it easy to learn about this stuff.
Absolutely fabulous content that's beautiful but dense without assuming too much knowledge about microbiology. I never thought I would be drawn to the subject and had no idea that it's this interesting. These videos really convey just how amazing the microcosmos is. I adore the evolutionary bio that you incorporate as well, which makes every video even more profound. My mind is blown every time you post one of these
Mmh bet u do Karen
Seriously. Beautiful. Great voice, entertaining information, gorgeous visuals. Incredible. ❤️
Possibly the most clearly-spoken narrator on TH-cam.
Barely a few videos, and I'm hooked. How is this possible?
Just like you? :D
@@PinataOblongata just like you!
couldn't sum it up better :)
Im 13, but this series (and spore) but mostly this series has really inspired me to make a game based on the functions of single celled organisms, and they eventually evolve. (Again, like spore). I’ve learned Python well enough, since I’ve been trying to learn it for years, but I know im going to need to know more about programming. I am going to create this game when I’m older. I’m dead set on it. But anyway this series is freaking amazing!
NNI7 Python is not a particularly good programming language for anything with graphics. For making games I sincerely advise you learn C++.
Marcus Bergman alright thanks!
NNI7 NP. :) I figured it's a good thing to know, so you don't realize it hundreds+ hours into the project :D
"They are each a little soup that wants. Look at them... wanting."
Gives me chills
I cannot imagine how wonderful this gem would look in 4K!
I had to watch this video like 4 times, because I kept falling asleep. Not because it's boring but because this series is so soothing and wonderful to listen to.
It's so nice.
It's like a lullaby.
10:00
I want a poster that says, 'a little soup that wants'
This gives me nostalgia from Spore.
The first stage was one of the best ones
These have been more informative and tangible than my classes as a microbiology major haha
This narrator is due for an award if you ask me. The character, wit and pacing are artful. Keep it up!
Yesss so stress relieving learning about the characteristics of micro organisms! Always wondered how they moved in such a sticky liquid as H2O
Hank on Sci-show, like a triple shot of espresso.
Hank on Journey to the Microcosmos, a cup of chamomile tea.
Welp, this is my new favorite youtube channel. Great hd images of the organism actually doing things instead of stained on a slide, educational narration and relaxing pleasant music, Im completely hooked. My only complaint is theres only a month and a half of vids and I watched them all! Cant wait for the next one.
I love everything about this channel. The photography is absolutely gorgeous, the narration is both soothing and superbly informative. It’s always a treat when a new video notification pops up.
"Look at them, w a n t i n g." Hank is ether enraptured by science or he has developed a god complex.
I think its both
I'm inclined to choose the latter.
Yes.
Yes.
This channel is the best.
Helpin insomniacs pick up some knowledge while their meds kick in. Thanks for the chill ride Hank, your voice with the music is so soothing
Absolutely in love with this series. The production, narration, all of it.
Bruce Lee: be like water
Amoeba: hold my beer
i’m always so excited for new videos from y’all :D
I'm an undergrad biology student so i know most of the stuff that's discussed in this series but this is so well presented that i cant help but be awestruck. The script is beautifully lucid and informative, Hank's narration is almost therapeutic and the microscopic footage is sublime. I love this channel. It's like my ASMR-y revision after a week of bio classes lol.
TH-cam algorithms brought me to this channel. A rare thing for YT to actually promote quality content.
Ah I love this series, so good x)
Can yall do viruses next?? So many different kinds and interesting
Such a beautiful series. Very informative while somehow being so relaxing and almost cathartic. I absolutely love it. Don't stop doing what you're doing, y'all!
I haven’t had much time for watching TH-cam videos the past 6months... but this series has single handedly brought me back. I even showed it to my grandpa 😂
What a great channel! Would yall ever do a video on virus/ bacteriophage? I'd love to see it!
They wouldn't be able to see them like the structures bacteria and archaea use to move viruses are too small to see with optical microscopes. You need far higher magnification than the level of bacteria if you want to see most viruses the only exceptions would be a girus (i.e. giant virus) that infects Eukaryotes with massive genomes that code for their own machinery rather than just hijacking their host.
I agree with the comment above about how difficult viruses would be to see since they're usually tiny. Also, being parasitic in nature, it would be tricky to grow them and they would spend some of their life cycle inside their host where they would be even harder to see
Ah, thats disappointing. Makes sense though.
thank you Hank, very cool
thank you Grimtin10, very cool
Thank James instead. He is the actual real deal here.
Your program is an itch I've never gotten around to scratching. Thanks so much.
In the closing seconds of this footage I loved the use of the word 'wanting' to describe these tiny packages of chemicals going about their survival processes.
I love this!
But I would have liked to see more of the flagella. I feel like it only showed one, and that one didn't really even move the cell.
At the very end of the video there's a cell swimming along. If you look slowly you'll notice it has a flagella
He's like the Bob Ross of microcosm 😂👍
Awww man, I binged all of these. Great work!
Now give us more, we NEED more!
After an annoying night, had an argument, felt ill and couldn't sleep my favourite new channel posted! It was like mana from the Heavens, the relaxing music and Hanks quiet narration. This channel is fuelling an interest into microbiology that I never really had.
I've always really liked Hanks voice for some reason also would be the bomb to see a video on the Hydra or maybe yeast. Keep up the great content.
I wish I could shrink down and ride one of these puppers.
Best comment I've seen all day ❤
No, Everything eats everything else you will be asorbed.

I love when the little bugger paws and seems to look at and communicate with us.
Observing microorganisms has been a dream of mine since I was a child. Fast forward 2 decades, I am now an undergraduate in physics(I like physics, too) and I have almost forgotten about this dream of mine until I discovered this channel. You and your team rekindled my curiosity for the wonderful world of microcosmos and I am so incredibly elated. Please never stop making these amazing and priceless videos. Keep it up!
I love how the music in these videos sounds like if it was made by a band of slimy translucent DJs
We don’t keep parasites around because they mess with animals.

Not all Ameobas are brain eating... Just like not all human... are vegan... You get the idea.
Is there a “That Brain Eating Amoeba”
This has been the most visually stunning ep so far. Many scenes just beautiful artworks that would make cool desktop wallpapers.
I love the slower, whispering pace. It's so relaxing and peaceful.
"They are each a little soup... that wants." - that's straight up poetic right there.
Though you do not have pictures of them, how do the Sporozoa move? Also do any occur maybe in plants? By their name they sound like Fungus.
Sporozoa often have flagella during the mobile part of their life cycle. Others drag themselves along over other cells. Some turned out to be fungi, and others are apicomplexans like malaria.
@@honourabledoctoredwinmoria3126 Ooooh I see. So I am guessing like Viruses they are largely mobile during their spread to other cells/hosts?
Not only are these videos fascinating but the typography and music is spot on; they fit the images perfectly.
The best episode in terms of narration, that last bit - really majestic. Amazing work
Edutainment worthy of Sesame Street and Mr. Rogers... for big kids.
pseudopodia is Greek not Latin, pseudo in Greek means false and podia is the plural of pous (like Octa-PUS, meaning eight legged). Pous or podion was later latinized to Podium but that doesn't make it a latin word, especially when the etymology of both words (pseudo and podia) derives from Greek.
Dimitrios Spyridon Chytiris Hence where “Greco-Roman” comes from. When Rome devoured Greece, Greece became a symbiotic organelle of the larger Empire. The two ancient cultures merged so completely over the next 2000 years they became a new thing altogether by their shared DNA (knowledge, language, art, science, etc) with each other, yet still containing their original strands like mitochondria. When the city of Rome fell in the fifth century the Empire didn’t die, it just packed up shop and moved to Constantinople for the next 1000 years.
@@LordTelperion how is tha reply changing the fact that the word is greek? and also i am familiar with my history, i am Greek..
i really look forward to every episode.. thank you Hank and Jam
Yes, this series had quickly become a favorite of mine. The narrator and choice of music work so well together. Also it's very well written. 💚 Thank you so much and please keep this going!
Hi
hi
Hey
Nooo, Hank! Pseudopodia is Greek, not Latin! This isn't the first time you've made that mistake, either - in Crash Course Psychology, you said that Psychology was Latin instead of Greek as well. I know it seems pedantic and nitpicky to point this out, but that Crash Course video was one of the first videos I ever saw of yours, and having that mistake within the first thirty seconds of the video made me not trust your information for a couple years. I know better now, thankfully, and love all your channels. I just feel like you should know about this stumble if you feel the need to point out etymology.
Signed, a pedantic Classicist
One need not be a classicist, pedantic or otherwise, to take your point of view. One need only be pedantic about language in general.
I almost typed out a very similar message. :')
I've had a very similar experience with Hank's content.
I adore the videos he's involved in. Etymology has been a relatively consistent source of "Nooo, Hank!" moments though haha.
"Leukocyte" comes to mind. Poor Greek... Don't neglect it!
Don't apologize. After a few compliments, some people with superiority complexes tend to believe they can say whatever they think they know as truth without even bothering to double check if they may be actually mistaken.
@@adjiar lol 'superiority complex'? Me thinks thou doth protest too much....
@@AdamTait-hy2qh I do lol. If you follow this guy's channels, you'll see he thinks way too much of himself now.

I love this channel so much! I didn't realize how interesting and beautiful microorganisms could be. Can't get enough of them and the chill vibe of this channel. Keep up the good work!
Absolutely loving this series , it's a world rarely explored but just as fascinating and diverse as watching a documentary on the Serengeti. Keep up the amazing work !
How do Protozoa get around? Eukaryote.
What microorganisms are on top of their own foodchains?
Zach Hauser, the huge amoebae are up there, like Amoeba proteus. They’re so big that other microbes would have a hard time eating them.
On a binge of all your videos,
So informative and fun to watch!!

I love people that explain things in English like this, slow but steady and comprehensible. Most English education videos, they talk fast and I unable to understand a thing especially when the subtitles are auto generated. I'm not English native speaker and I find this way in delivering idea is fascinating and understandable. Well done, Journey To Microcosmos, you earned another new subscriber !
I’m curious as to why you don’t use “amoebae” (uh-me-bee) as the plural form of “amoeba”. It’s just a fun word to say!
Evi1M4chine, these organisms were named in Latin. Most don’t even have common names. “Amoebae” is also just a fun word to pronounce, and it’s much less of a mouthful than paramecium and half the other organisms that show up under a microscope. Since it’s just Hank narrating, the weird spelling wouldn’t even have to be shown.
Ive been calling them "Amoebas" thought my whole life ._.
AlphaAmoeba, you can still do so. It’s not really wrong, and non-biologists will give you a weird look if you say “amoebae”.
@Evi1M4chine- Im curious how you came to the conclusion that constructs like 'aeae' are 'deliberately' hard to pronunce. You also said English was a 'silly and limited' language.... but part of that is because of alcoholism, somehow?! And using Latin is even sillier, and of all things 'Snobist'?! Im just sooo confused right now. I mean, the OP was just commenting about the pronunciaton of a word, and how they thought it was fun to say.... but, ya kno, dont hold back, let us know how you *really* feel! lol
They all drive Teslas 🤑😂

This might be my cellular biology degree talking but this is absolutely one of the best channels out here!!!
love this channel, it reminds me of my first year of ecology and enviormental protection.......especialy it reminds me of one proffessor that was so freaking amazing you could listen to him for 6 hours straight and not get bored, sleapy and still be able to memorise all stuff he talks about....
pseudopodia comes from greek actually. Pseudos: fake and Podia: feet
I just dont see how [insert x number of years] is a sufficient explanation for how these things develop, or how you can move from a single cell to a multi-cellular organism like humans when the micro world is already this staggeringly complex to deal with in its own right. Just doesnt add up and a rather cheap explanation.
It's because everybody keeps forgetting that all things evolved from a common ancestor; and these aren't it. These are what we imagine it looked like after they got to the moving phase; but in truth these wee things are as evolved as us, from longer lineage too.
Am I the only one who ends up getting closer and closer to the screen during these videos, to see more, closer...more! I love these wee beasties, and the nice narratives. Thanks!
Was struggling to find good microbio content on youtube before this channel started, this is so awesome! Greatly expanding my understanding of the literal HOW single celled organisms DO anything

was thinking to myself "cmon man, I want to see a sporozoa, they can't be that bad." Then I googled it. Woah, those are some nasty parasites. Definitely a fantastic idea to keep them as far away as possible.
Best series on youtube at the moment, hands down.
I wouldn't want to risk getting malaria for a youtube video lol
