I love how Hank Green is trying to not sound like Hank Green

Diatoms: has oil US: Looks like these diatoms need some *freedom*

"[They] provide us with every fifth breath we take..." Wow that phrasing really puts it into perspective.

This channel is an absolute treasure. Please keep this series going for as long as possible. Fantastic narration and use of wonky underwater sci-fi music and sounds effects lends to the authenticity of ride. Like hopping on the Magic School Bus and watching everything up close.

Andrew Huang is really the unsung hero of this channel... the music is always so perfect for the video and narration, calm, clear and reserved, good job man

This is my favorite series on KZfaq right now! Beautiful shots and writing 😍

These little cuties are also important for dating rocks in geolgy! We see there cool silica structures in sedimentary rock sequences. They even form part of the makeup of chert! 😊 Nice to see them alive here though. Thank you for your video.

And they are called “Diatoms” because their frustules are always made of 2 halves that are nearly identical and interlocking. I say “nearly” because one side is slightly larger so that the other side can fit inside to form the interlock.

Is Mr green talking in this way because he's trying not to frighten the single cell organisms?

Diatomaceous Earth is also a natural pesticide - the glass frustules cut up ants and other insects as they walk through, making it an impassible barrier. Fascinating video, thanks for making this series.

Wow, these little glass friends are rad as hell.

every video you release brings me one step closer to buying a microscope and checking those little things out myself

Everybody drop what you’re doing! Journey to the Microcosmos video.

As someone who works on them on a daily basis, I thank you for making this wonderful video. Those tiny glass-encapsulated plants have remarkably complex shell (frustule) structures, with functions that are largely unknown to us (like how they use mucus and raphe to move). I always love seeing them under the microscope in my labs :)

My heart fills with joy every time i see one of those videos. On top of being extremely aesthetically pleasing it's just so neat how all those microorganisms manage to function on such a small scale

I don't remember this part of Spore.

As a germinating medical student passerby, I suddenly became curious as to whether the raphe of diatoms and the raphe of the raphe nuclei both describe a similar structural shape. I also found the actin-myosin movement hypothesis very interesting. I really love your videos by the way for their beautiful background music, offerings of artful microscope views of the elegant, mysterious creatures you describe to us, and superb, delicious and insightful narration that awakens my curiosity of the microcosm. ^^

I have no idea why the algorithm decided I might be interested in this channel. But I thank it for it.

3:12 Well, _one_ of the daughter cells is going to be smaller. The frustule is composed of two almost identical sections called "thecae" that overlap a bit--basically an expansion joint. However, one theca is slightly smaller than the other. When a diatom divides, each daughter cell gets one of the theca (which will become the larger theca for that daughter cell) and then each produces a second (smaller) theca. So, the daughter cell that gets the larger theca will be about the same size as the mother cell was.

After an extremely vexing weekend, it is so very nice to see a video from this channel. It's so much nicer than the macro world. It's so much quieter than "big life." I sometimes wish to reincarnate as a diatom or something. Being human, these last few days, has really really sucked. Thanks for making these videos. They make the larger world more bearable by drawing us into the smaller one and letting us remember why life is worth bothering with.

This is like a cup of hot cocoa in a form of a pop-science show. Soothing.

I think you should also write a book with some of the imagery you have captured,. it would be a fantastic learning tool.

I feel that Hank becoming a dad made this style and delivery possible. It’s good storytelling for bedtime. I wish I was your son, Mr. G

Hank talking like this simultaneously amuses, relaxes, and disturbs me.

When I die I want Hank Green to do my eulogy.

The best channel I've ever found about micro biologi. Lector is perfect, speeking witch love and passion about the subject. Visual representation is very clean and high quality, great job. Background music is exactly as it shude be. Thank you once again for your hard work. Greetings from Poland.

Hank's voice over and pacing is phenomenal, what a treat of a series.

the music, the narration, the imagery...no nonsense, nothing annoying - thank you !

"Through the Living Glass, and What James Found There"

Watching this is the microbiological equivalent of hearing Bob Ross' soft voice while he paints - top class, keep up the (relaxing) work

I’ve heard Hank almost everyday for as long as I have the internet and I’m 29 now. So I guess a LONG time. My first www obsession, Vlogbrothers. But this, this is my favourite version of Hanks voice. Thank you Hank. You are a true hero.

diatoms are what got me so into the "microcosmos" from a young age, I vividly remember seeing pictures of diatoms and thinking how beautiful they were.

You've shown so few shapes. They come in so many beautiful shapes.

fometimef thefe videof can really fuprife me with interefting Factf! (ca.1499)

You literally can't make these videos fast enough for me. Absolutely captivating. Spellbinding, even.

I love Hank's narration style

These are the base of food chain in sea, everything from small arthropods to big whales feed on them. They sustain life in the sea

I am ready to be scared of drinking water again

Diatoms: Beautiful, good for the environment and thoroughly absorbent.

I appreciate this show so much, especially because it always puts things in my sometimes complicated, sometimes stupid macro life into perspective

Bruh, muscular jewel plants. That's what I call an epic gamer moment.

Diatoms are the craziest thing I've heard of in, truly, years. I'm so glad they're a cool thing too! This channel has totally impressed me. I like sciencey stuff but had no idea I'd be THIS into microscopic little dudes.

You have one of the most pleasant to listen to voices ever. If all teachers were so engaging a lifetime of learning would be our ultimate goal

Diatoms are my favorite unicellular organisms. I’ve seen beautiful art created using individual frustules. I’ve also sprinkled D.E. around my apartment to stop carpet beetles. They’re also so incredibly important to micropaleontology. Diatoms are just so great.

So we have Andrew Huang on the music and Hank Green of SciShow on the narration. Truly majestic.

The narrator's voice is so gentle and pleasant, he is probably the only person in the world that could sell me some outlandish idea such as "cockroaches are not the spawn of Satan". On a serious note, this earth is absolutely mindblowing. There is magic everywhere, if only one has eyes to see it. Thank you for the videos.

Its amazing how much we depend on this tiny organism. They help provide us with the beer we drink on the Superbowl, the wine we drink when we take our wives out for dinner, and the cat litter that keeps our homes from smelling like an allyway. yet they know nothing of who we are and what we do to in our day to day lives, its important we treasure these micro gems and there roll in the world.

Their frustules are extraordinarily fascinating, both as structures biologically manufactured by microscopic organisms out of silica & as stunningly beautiful examples of mathematical - & especially fractal - symmetries. As you alluded to, they are actually extremely porous, with the frustule surfaces of some species composed of a pseudo-honeycomb of perfectly circular holes (themselves filled with even tinier hole mesh patterns) organised to use the space in the most optimum arrangement possible. They're also being investigated by scientists for the optic effects (similiar to that of a butterfly's wing) that are produced by these porous structures, as well as the long-term potential of using genetically engineered organisms (perhaps derived from Diatoms) to make both nanoscale & macroscale structures using biologically derived silicates. eg: Structures composed of soap-bubble thin silicate films, stacked in layers of varying porousity, which could be used to purify water for drinking. ~ ~ ~ How badly their numbers - & necessary oxygen output - are going to be affected by Global Warming induced Ocean Acidification, is also a major concern.

This series is absolutely wonderful. Always looking forward to the next installment. Keep up the great work!

Thanks Hank and James! I'm learning a ton from this channel, as well as taking in a few zen moments.

2:23 wait...... I think I've seen one of those in science class! We didn't know what they were so we just shrugged them off like they were some debris or dirt. Thanks for letting me actually know what they are!

this video is so meta. the narration, the images, the music... chefs kiss from me.

Wait what? 1/5 of the oxygen I have breathe in my entire life came form them... Thank you tiny little things.

Beautiful creatures that *make Oxygen for us.* We can be happy to have them on our planet !

Hank!! Your voice!! How can it be so sweet?

I really want more hosts to speak slowly and pause between sentences as you do in these videos. They're both deep and simplified to a degree I can comprehend this foreign world. Love them dearly. Thanks!!

This channel is absolutely amazing, I hope it sees lots of growth. Keep it up!

HERE THEY ARE!!! HERE THEY ARE!!! I've been waiting for this!!! Diatoms are my absolute favorite microorganism, I love them. ;u;

Thank you Microcosmos team and thank you Diatoms!

that was the longest 7 minutes of my life, and the most relaxing

Microcosmos and the Valleyfolk are my two favorite channels on KZfaq currently, so that gives you an idea of my personality lol

My husband as he looked over my shoulder: "Why is that rice running so fast?"

Things can't get beautiful than this 😍😍😍😍😍 I'm very lucky to hv found this channel.... Thank you sooooooooooooooooo much Hank 💓💓💓💓

Watched it at 1:25 playback speed. Made it much nicer to listen to.

Was peacefully enjoying this video untill he said that these lil dudes had oil in them. Now the US government is here to give me some freedom.

Diatomaceous earth is also a very effective environmentally friendly insecticide.

Little did I knew that someday I would crave more video about the microcosmos! I tried other similar channel since I discovered this one, but this one is definitely the best.

I can't believe I didn't know about this channel until now! I love Hank on many other programs including scishow! 💚

This channel hits all the spots

The background music and imagery remind me so much of the anime Mushishi. It's unreal.

My first real experience with a good microscope was in my High School Biology class. I was hooked on microscopic pond creatures and algae ever since. My first scopes would be considered toys, but I did find satisfying results. I now own a laboratory grade microscope... but never obtained visual quality like I see on this page. Thank you!

These videos make it easier to deal with the world today. Hank, your narration is soothing and patient and this content gives me something else to focus on. Thank you all for your work on MiCo.

I love this episode! ♥️

God damn i love this channel so much.

These things are incredible. They are a beautiful reminder of how connected everything on our planet is. Every system, every living thing, every substance.

This is the greatest chennel ever. You guys should be getting film making awards....

This is beautiful, such an underrated channel.

learned it from high school : didnt remember shit learned it from this channel : waw this will forever be remembered

Wow, I kept thinking, "This guy has certain mannerisms just like Hank Green" but I was like "Hank green doesn't sit still like this or be this calm and soothing..." then at the end I was nearly certain it was Hank Green and had to check the description; it IS you! :D

I watched this with my cats and they would like to express their gratitude to the diatoms for helping to make their cat litter. I, however, am much more thankful for the beer.

Am I watching some kind of sciency asmr ? :o

Not only did they craft glass armour but they didn't even collect sand and smelt it for the glass... AND THEY'RE NOT IN CREATIVE MODE EITHER! Just how? They must be hacking...

hank green has such a distinct, recognizable voice.

This channel has caused me to begin looking at buying a microscope. After your 500k livestream and finding a microbe that has a symbiotic relationship rarely discovered/studied, I was sold. I have many glass jars for samples. I have started to sink money into texts about microbes and freshwater ecology. Next imma buy a microbial ecology text. And then the microscope. I’m ready. In my microbial ecology class I learned that the “ecosystem” that microbes live in are ~2-4cm. There is a lot to discover simply by observation and time. Thank you for your work, Hank. Amazing stuff.

I had been longing for this episode. I've built a simple microscope, I'll be visiting a pond soon.

watched the entire thing. very nice.

Wow! An informative scientific presentation without a single word promoting the Evolutionary theory. Well done!

I love this show!! Every episode get me so invested, and I always come away having learned at least a few new things. Thanks, Microcosmonauts!

They remind me of floaters that are on the surface of our eyes

OMG!! they're the minecraft beds! There are some villagers fr*cking down there!

Another awesome video- thanks, team! And a special shout-out to Andrew Huang for his really great soundscapes- they are the perfect compliment to the videos and Hank's narrations!

For I can't help.....falling in love with this channel.

I'm wondering if they move though a similar system as airplanes. Maybe the mucus they excrete somehow reduces the fluid pressure in front of them causing the pressure behind them to push them forward.

Still waiting on you releasing still shots that I can use as wallpaper backgrounds

Im always fascinated whenever I hear diatoms....I first heard about diatoms in pre university education or school maybe and at the moment I heard about them, I suddenly wanted to know more and more about them, and now I'm studying a whole topic on these species in masters...feels so happy...

Something about this channel hits a perfect balance of relaxation and education that I never knew existed. This is definitely Hank's best work.

Diatomaceous earth also helps us to produce dynamyte. 💣

".. and also they're just really nice to look at." Yeah, I'd appreciate uploads of longer uncut footage to just zone out to

I LOVE SCIENCE! I LOVE BIOLOGY! I LOVE LEARNING!!!

yay! I have searching for diatoms videos the past week. This is a treat!
