I'm shocked and pleased. Seeing this video in 1440p makes it practically indistinguishable from what I remember seeing in my Master's research project, which was about the formation of bacterial biofilms on the head of C. elegans. So crisp, so detailed. James and Hank, well done!
You know the world is getting more interesting and accessible by the second when you realize master thesis level video material is being watched by over 50,000 people in less than a month basically for free.
I got a microscope the other day thanks to you guys! So far I've found 2 tardigrades, 3 rotifers and a bunch of little guys I'm not sure what are, but they were in a clump of moss on the roof of my garage! Not sure how they got up there but I'm happy I looked! Also got a sample from a local pond that I'm finding tons of little critters in! Can't wait to see what else I can find!
*Me: "Oh cool flatworms! Guess I'll learn some biology"* *Video: "It definitely looks like it had 3 minutes to prepare for a costume party and decided to go with the classic "old bedsheet with eyeholes" ghost costume."*
Primo, when you watch a nature show about tigers, do you expect a discussion of tiger bladders, see a cross-section of a tiger heart or brain, or the chemical composition of tiger mucus? Or do you expect to see a tiger in its habitat and hear a narrator waxing poetic about tiger movement? If someone says, "Journey to the Macrocosmos" or "Journey to Madagascar", do you get the sense that biology is what it's about? It's called "Journey to the Microcosmos", not "Journey Through Biology". They are just showing us the wonders in the microcosm.
Just discovered this channel when I heard it was discontinued. Hank and all - Thanks for your work on this, it's fascinating. I'm working my way through all the videos.
This - is what 4K TVs been made for. The picture quality is absolutely jaw-dropping. Thank you so much for doing this! Gosh, I’m so lucky I’ve stumbled across this channel.
Good thing to keep in mind though is that flatworms are secondarily acoelomate, they’re traditionally thought of as the “basic” branch of the animals leading up to more complex stuff but they’re really nested pretty close there with “complex” other spiralians like mollusks and annelids. They had a coelom once but got rid of it cuz they’re too cool for it 😎
This is one of the best shows on this platform. The microcosmos never fails to fascinate. Science is just awesome! This is right up there with Bill Nye and Carl Sagan!
A scientist once said that if all the matter on Earth was removed with the exception of the nematodes, we would be able to see the outlines of mountains, valleys, seas, rivers and other natural features formed by the masses of nematodes. Forests and cities would be dimly recognizable by the presence of specific kinds of nematodes, and we could even locate plants, animals and even ourselves based on the parasitic nematodes that infest each species.
This really brings me back to Gr. 11 biology when we covered the major phyla and each evolutionary advancement in each. It was amazing to see the complexity ramp up in each new phylum we covered, though each leap was enormous. Sponges to jellyfish to worms etc on to chordates. Our spiny phylum 🙃
*I remember when I was but a teenage larva in Planktonic High, my Gastrotrich buddy and I were part of the high school band. Later on we branched off and made a band of our own to impress the nematode babes at our school. We called ourselves the **_Mictic Sticks._** Quite the naughty name, I know, but let's just say that we were swimming in roundworm with each performance.*
Man, James has really upgraded his equipment... that's some amazing video. And flatworms are topologically a sphere, and we are topologically a torus, as is a coffee cup.
I love this show, it informs my visualization of my studies in ontology and ecology. Thank you so much for these. At the end when you say "Thank you for coming on this journey with us..." Every time, I say allowed "you are very welcome."
Whoa. What spectacular video with your new DIC microscope!! Obviously, James has been having a lot of practice and fun with these new incredible images!!
one of my lecturer's in uni was quite partial to invertebrates. She had giant snails and flatworms as pets and was very protective of them. Can't say I blame her, I love my red worms and spoil them rotten.
Wow. Not only are quality of these videos excellent, and the information facinating, but I gotta say your narration not only borders on poetry but often is poetry. Cudos.
Wow! Thank you I didn't know worms could be captured so beautifully. I see worms as I've never seen then before and they are captivating. Thank you °~.♡.~°
I know this isn't very specific, but they look like a type of euglenoid. Without more close-up or focused images it is hard for me to say for certain or with more granularity. I'm no expert on the subject, but I've looked at enough lake water and pond water under the microscope to at least call that an educated guess. Anyone who has a better idea or more experience with them, feel free to respond with it!
This is a nice video, but it makes a crucial mistake around 4:45: annelids and humans do not share a coelomate ancestor. Coeloms evolved independently in the two ancient rivaling branches of bilaterian animals, the deuterostomes and protostomes. Humans are deuterostomes; annelids, nematodes and flatworms are all protostomes, so despite having or not having a coelom to different extents, they're more closely related to one another than they are to humans. Actually, for those deuterostomes and protostomes that do have coeloms, one of the most recognizable features of the two groups is that the coelom is created in different ways during embryonic development. In deuterostomes a part of the gut pinches off and becomes the coelom; in protostomes the coelom is inflated like a balloon from a solid mass of embryonic tissue.
I just observed a small worm under microscope with 100X very similar to the worm pictured at 11:38 identified only as an annelid. It did have a segmented body and filaments or hairs along its length although they were more numerous.
Some time ago, I've observed an Annelida species that looked like it could be Stylaria lacustris. Very interesting to see it properly instead of in my very amateur microscope. And of course interesting to hear how it's built.
Seriously love these videos mate. Been watching from the birth of this channel and its never become any less fascinating. "A the inside a tube" will stay with me. :)
Emmy wished on a dragon scale And that's what started Dragon Tales Around the room, the dragons flew But Emmy and Max knew what to do They climbed on the backs of their dragon friends Now the adventures never end
Question for Sir James: What is the colorless, multi-chambered organism immediately below the flatworm egg, at 8:18? And are the moving entities near it's center internal to the organism, or are these bacteria behind/before the organism?
Is it possible to connect a highspeed camera to the microscope? It might be interesting to see those super fast moving "hairs" (I forget the correct term) in slow-motion of, for example, rotifers.
You show us auch fantastic pictures every two weeks of organisms in which I see all kinds of parts acting together. Unfortunately I, and I guess lots of other people too, have no idea what all these parts do in the body of these organisms. Could you maybe make a (series of) video(s) in which you describe their functions?
I wished you had footage of flatworms regurgitating their stomach's contents post-digestion, just to see how much is there to pass through one's mouth in one go.
Whoa, today I notice 60FPS. The sweet silk-smooth movement of flatworms is fascinating! EDIT: This is crazy. I'm now fairly sure this is your first episode with 60FPS, or at least the first that has both high framerate and speedy wiggly things?
Found this channel a few days ago, really digging your narration and footage, any chance you could you could do a video set in a context, for example, the micro cosmos of a drop of rain, a puddle of spit or even like part of a living plant/animal such as a fly trap or living human cell? Thank you for the content
I’m just a fancier tube inside of a tube with some fancy attachments and I’m on UA-cam watching a video about other less fancier tube-within-tubes.
How many holes does a human have?
_cue vsauce music_
And via a series of tubes a Londoner can watch it on the Tube.
Totally tubular!

Dismythed & JWA technically this still is educational description.
The real time tracking shot as the flatworm is swimming at 6:00 is impressive!
Yes, how'd James do that?? Beyond cool.
So now comes the question, do they think?
@@rameyzamora1018 i think it's based on the controls of the microscope they use.
it's probably sped-up footage
@@Musicsage They are usually pretty good about annotating when it is sped up.
Just discovered this channel when I heard it was discontinued. Hank and all - Thanks for your work on this, it's fascinating. I'm working my way through all the videos.
its difficult to remember that these organisms are 3 dimensional. i always tend to think of them as 2D creatures
Well, these *are* flatworms.
@@ivy_47 being flat =/=2d

"That flatworm is a marvel, an almost unbelievable testament to the power of evolution."
Why did this line make me tear up?
Just found your channel from a comment on PBS Eons - very glad I did! ❤️
Welcome!!
This - is what 4K TVs been made for.

Thank you so much for doing this!
Gosh, I’m so lucky I’ve stumbled across this channel.
I’ve been begging for this one for a year lol
Next vid should be on nematodes
Your wish has come true :)
Me too :)
They loved it so much they wanted to wait for the better equipment
@Gupie Dziecko nice
I love their little eye spots. Blows my mind that they can have a functioning eye and interpret information from it.
Good thing to keep in mind though is that flatworms are secondarily acoelomate, they’re traditionally thought of as the “basic” branch of the animals leading up to more complex stuff but they’re really nested pretty close there with “complex” other spiralians like mollusks and annelids.

Its actually incredible how zen these videos always are. It's as relaxing as meditating for five minutes tbh

No guns or loud noises here. Love it. Cheers to the worm in all of us!
Wow the images here brought back some memories
Your new microscope tech is absolutely amazing! I'd love to see some of the earlier episodes remade with it.

6:15 i LOVE this music.. Hits my soul so deep I can almost see the beginning
The start of the explanation of the worms sounded like a zefrank vid
The new microscope is amazing and the video is incredible. Congratulations!
I love this channel so much it's so calming that I've watched this video about four times and still aren't bored of it
Wow. Not only are quality of these videos excellent, and the information facinating, but I gotta say your narration not only borders on poetry but often is poetry. Cudos.
2:42: "... beyond the *scope* of the *micro*..."
Hank, we can hear your big grin.
Mid roll ads ruin the experience of watching these beautiful videos
Sorry about that! UA-cam now turns those on by default and I forgot to turn them off - Matt (Producer)
I didn’t expect this video to be a review for my Animal Structure and Function university final exam. Thank you guys!
The footage in this video is Absolutely Brilliant! So sharp and vibrant. You guy's are Amazing. Thank You yet again for the wonderful content.👍
I fought my worm phobia to watch this episode bc I just love this channel so much.
These should be used in EVERY Jr. Hs. Biology program. Well done to all involved.
This really puts into perspective how lucky we are to live on a planet with such complex organisms
I see what you mean, but it's not really lucky. If pur planet couldn't/didn't support complex life, then we wouldn't be living here.
Leeuwenhoek would be so pleased to see how far we've come in understanding and viewing his little "animalcules".
This is my favourite series on UA-cam
Wow!
Thank you I didn't know worms could be captured so beautifully.
I see worms as I've never seen then before and they are captivating.
Thank you °~.♡.~°
one of my fav channels on youtube, always exited to see you upload, thanks :)
Awesome quality and 60fps?!!, its Christmas everybody
Are we ever going to tire of DIC? Ooooooooooooooo! Aaaaaaaaaaa! [how will we ever do brightfield again?]
phase contrast is still cool in how it lights things and emphasizes the blurry under standing of the microcosmos
An improvement in the visuals. Very good, thank you.
THOSE LITTLE GREEN DUDES AT 1:46
What are those?? I have them in all my pondwater samples and I haven't been able to identify them.
I know this isn't very specific, but they look like a type of euglenoid. Without more close-up or focused images it is hard for me to say for certain or with more granularity. I'm no expert on the subject, but I've looked at enough lake water and pond water under the microscope to at least call that an educated guess.

Could be Euglena viridis or possibly be grasilis. Unfortunately I'm no expert either just an observer.
Any chance a future video will go into the "eye dots" on some of the creatures featured up to the present?
Wow, such amazing detail now...these videos just get more and more amazing.
The visuals presented by the new microscope are truly and utterly mindblowing, and I look forward to the next video.

Would mind making a video should the microcosmos of our bodies? Like blood or skin tissue?
Could you do a video on the very largest of single cell organisms and bacteria?
Hi, what kind of microscope do you use?
I love your channel. I've been watching since the first video. Educational and the narration is soothing.
The creatures in this messy world are so beautiful.
How to do you start your microbe cutures?

Is it possible to connect a highspeed camera to the microscope? It might be interesting to see those super fast moving "hairs" (I forget the correct term) in slow-motion of, for example, rotifers.

what are all of those other organisms swimming around the rhabdocoela?
Wiggle, wiggle, wiggle...wiggle, wigle.
This flatworm got a bright future behind it!
Your videos are absolutely profound!!!! ❤️
Do annelids have top & bottom sides?
Can you explain the structure and function of eyes on some of these microbes? How useful is light at such a scale?
My skin crawled the entire time watching this... I have a phobia of worms but I couldn't stop watching
Only one of 2 channels I hit the bell on.
3 for me. This, PBS Eons, and Graystillplays.
If you play this at 1.5x speed, you get regular speed Hank in SciShow.
6:40 what is the other organism on the right of the dalyellia??
Absolutely stunning DIC!!
Finally Plathelminthes 😍
Can you provide the microscope model used for recording these images? And type of optical technique, PC, DIC, etc. Thank you in advance!
Thanks for the amazing episode as always!
"I'll watch some video while eating" great idea...
Are those spirochetes at 8:29 in the lower left?
can you take a lateral view of the microcosmos?

I would love to see a video on dieffenbachia idioblasts. the dieffenbachia have cells that shoot crystals and its crazy. ive never seen a video of it.
How does this channel turn the ickiest thing into something soothing
I vote for a collab with Ze Frank - "True Facts About There Flat Worm".
Cause that's how the flat worm do.
I liked the worm-music in the background of this episode
6:40 looks like a smashed down platypus- also great video!
That first flatworm is like the ghost of worm on a string.
