Just for your information, the heliozoon at 07:03 was eating two Vorticella cells. One of them was already ingested and the other one was trying to escape, well, it couldn't!

Finally... I created this account to ask for this very video
Do you feel you're being accurately represented in the media?
how does it feel to be talked about by beings of infinitely more power and complexion
It only took a year too!
@@zulimations "COMPLEXION"!
I'm sorry, I don't mean to be mean. Just. That's an unintentionally hilarious wrong word. We have SO much more melanin than heliozoa do!
@@neolexiousneolexian6079 LMFAOO I’m not even correcting it, it’s hilarious
"...they lowered the temperatures, they found that the organism's axapodia shortened until they disappeared."
I think we've all been there, right guys?
I'm glad I'm not the only one who thought of that...
George: I was in the pool! I was in the pool! It's a result of the chemical connections holding the microtubials breaking down and the structure depolymerizing!

Specially the disappear part
Yesterday I was reading about the Victorian age. The Victorians had a particular hobby. They made art from diatoms and such. Really beautiful tiny tableaux only visible under a microscope. The patience and time these people invested in their art is not from this time. Diatom art as way to out your love and fascination for the microcosmos who would have thought that.
wait that is actually so ridiculously creative and unique and weird... im obsessed with this now thank you
6:03 "Look, babe... this is completely normal... it's... got to do with microtubules and stuff!"
Does it reflect poorly on me that I enjoy watching these little dudes eat? I mean sometimes Hank makes capturing and eating sound pretty brutal, but I'm over here cheering for the hunters.
We always root for the subject of the documentary!
Not only do they eat, but what goes in, must come out. I always giggle when they poop.
While we're confessing stuff, I always get hungry when watching undersea nature docs, especially the bits when predators are chasing "bait balls" of anchovies or such. I can't even watch "Finding Nemo" without craving fish & chips.
I always loved these things when I studied microbiology, not sure why. But I'm definitely a heliozoan fangirl.
Then surely you must know a lot about the formation and maintenance of axopodia
Ooooh, about time our spiky sunny bois get their own episode.
I think the real question is "Is it hunting if you're just waiting for something to land on you?" . XD
*trap door spider would like to know ur location*
"Hunting is the practice of seeking, pursuing and capturing or killing"..of prey. It's a useful but broad term, that can be split into active and passive categoties of hunting, and then split into more specific kinds, like trap hunting, which the heliozoans have in common with spiders, for instance. Then there's trap-door spiders and many different uses of web.
It's not that different spinning a web to trap prey, to growing appendages that do similar job. It might look funny/different but not to dissimilar to a spider hunting with a web etc.
If its consciously waiting for just that then yes it is hunting.
@@Galaxyofbrian : not to sure consciousness is either required or can be easily established/measured to any level of confidence. consciousness seems to be various brain related activities lumped conveniently together, in a human centric fashion.
@@bosscom6910 Big deal, they never leave moms basement
I am always happy to sees new Journey video! Thanks for the amazing way to see the tiny world all around us!
Some days i like Alan Watts lectures other days i paint with Bob Ross but Journey To The Microcosmos is something i almost come back to daily and my heart is very content with that
I want to see the microtubules grow in that spiral. I guess that is beyond the microscopic power of this channel's equipment. That would be interesting in a geometric sense. Perhaps there is a some paper somewhere that describes how it works?
It's always a good day when Journey to the Microcosmos uploads!
Lies! it is always a Monday.
@@ammendum9044 beat me to it!
My thoughts also
Yep! I look forward to them 🙂
True, their videos are quite calming.
You guys make the beginning of the week bearable
Every time I sit down and try to watch a new video I end up passing out about halfway through. It doesn't matter what time of day or night it is. It's just so relaxing.
Sir, you talk so beautifully.
As a student of biology, this is exactly what I want to watch on YT.
I just discovered the channel today and I Absolutely Love it.
Thank You Sir!
I love how fascinating and unique these videos are. Not every TH-cam channel gives you vivid mental images of a heliozoan riding a golden chariot in the sky.
As poetic as one can get... starts reciting scientific poems. Experiment was a success. None survived.
The shots you guys get with your new microscope are breathtaking and continue to surprise me. Keep up the amazing work!
Thank you for taking us on these journeys with you.
That water sample, is amazing; there's so much activity, plants, & animals, zipping around; I loved it!
Thank you!
i was so hyped when i first saw one and i love these guys ever since :D
I study English and biology. Your work makes the studing much better. Thank you for cool movies!
This video made my day infinitly better.
The beeping in the music behind the Brilliant plug sounds exactly like my alarm clock. I was very concerned that I was going to have to wake up and leave for work just after returning from work in a dream.
Thank you Team Hank & James.....Cool School as usual!!
So what you're telling me is that these amoeba like things actually have bones but they can expand and contract them at will! That's some SCP shit XD I don't know I haven't had my coffee yet
Amazing research when applied to ideas regarding hydraulic systems and structures.
Thank you for the content!! Can't wait to get my neices into the microcosmos!
🎶 Spikey, sticky sun.. won't you come.. and wash away the paiiiin 🎶
YOOOOOOOOOO NEW JOURNEY TO THE MICROCOSMOS VIDEO
I love these videos so much
I adore this channel, than you for making the mirco magic ;)
Nice footage.
Is it just me or does Hank speak significantly faster in this video? I mean ... not vlogbrothers-fast, but towards the end, when he gets really into the meaty science, he seems to be back to "regular-page-for-a-normal-human-being-without-ADHD". Almost as if the increasing density of science makes him excited again!
People with ADHD actually usually speak at a faster pace due to their racing minds and how excited they get when they actually care about something enough to talk about it, so I'd say him going faster makes him more ADHD-like, rather than less, haha!
Amazing, thanks for sharing :)
How much energy do the heliozoa use to rebuild their microtubules? Are they an actively maintained structure that the organism has to aggressively invest resources in, or are they a stable low-energy state that mostly automatically reforms on its own once conditions are favourable for it?
I love how much of science is just "let's break it to see how it works"
I love every frame of your videos!
pretty badass little creatures actually
Wow, I just now realized Hank Green is narrating this show...
But what are these funky critters bumbling around at 6:00 ? They're quite lively!

4:24 that one is having the time of their life.
2:41 I liked these tiny dancers.
2:05 This guy looks multi-cellular, even though I'm sure it isn't. Any guess as to what those are?
Some heliozoans have a silica shell, it could be that.
Looks likes the ectoplasmic net of thraustochytrids
I think they are maybe vacuoles waiting to fuse with the outside and fill with food?
Looking down on axopodia that are pointing up at the lens ?
I need a 10 hour edit of 2:57
Can you cover what autophagy does? Many people don't know how it works.
🇧🇷AWESOME !
Dope
They make me think of the "tanks" in the kraken wakes, I assume they may have been a direct inspiration.
nice
My life is happy (:
Why are the microtubules in a spiral pattern? And were those experiments just to determine things about the microtubules themselves, or did they reveal any behaviors of the organisms or mechanisms of the axopodia?
could some form of heliozoan life, with its resistance to cold & uv and ability to extend and retract its membrane, survive or even be successful living in bubbles in Venus' upper atmosphere?
What is the microscope you use?
I know that Lionel Richie didn't _actually_ write "Stuck on You" as a tribute to _heliozoa,_ but I'd like to pretend that he did.
Will you guys be offering the starter kits again? I regret not having the money to buy in before. Now I have it and it is closed😢
Same 😞
Just give us a bit of time and the microscopes will be available for everyone who wants to start their own journey! :)

@@JamsGerms thank you!
Fascinating. One wonders if there are ways in which the information gleaned from these studies will be used in the macro world. Recent experiments in materials science and architecture and engineering are "inspired by biology" - what might these spikes and their micro tubules inspire?
And how many pointed jokes can we make while discussing it, hmmm
A revolution is forthcoming in the polearm industry.
Imagine sewing, but with a pincushion that creates needles instead of storing them.
"Extrusomes." New fave word. Also "tubulin."
You should have added magnification scale to 0:37
A little living trap looking like a sea mine. Nice.
Do they eat each other?
Harry Potter & The effect of low temperature on these structures in the formation and maintenance of axopodia
Microtubules are basically carbon nanotubes.
I wonder if we could use those organisms to create massive amounts of them for us.
One heliozoon, two or more heliozoa. Something that belongs to a heliozoon is heliozoan.
Tubular!
A bunch of grad students wrote dissertations based on those microtubules
This is us ask why we do what we do at a fundamental lvl
It was not clear that these are unicellular creatures, they look like a ball of cells but they are not.
I think that when describing a microscopic creature you should emphasize whether it is unicellular or multicellular.
Is it possible in the future to indicate the type of microscopy used for each image alongside the magnification? E.g. light field, dark field etc.
That micro Organism could share some of its DNA with jelly fish.
It's weird to see the name Aleksandra as the last one in the alphabetical list, after the Z. I get it's in Cyrillic and that's why the position, but still..
Now I still don't know how those axopodia retract...
It seems that one end or the other of these microtubules that make up the "backbone" of the axopodia can be disassembled/eroded at will.
Similar microtubules are assembled and disassembled inside your own cells, to move things around (like chromosomes during mitosis).
(th-cam.com/video/5rqbmLiSkpk/w-d-xo.html for instance)
7:15 Somebody's doing something here on the upper left.

Heal leo so ah
Look up the Orch-OR theory of consciousness by Roger Penrose and Stuart Hameroff. Pretty interesting ideas about the role of microtubules in the brain And their potential role in consciousness.
I study neuronal microtubules and I can flat out tell you that orch-or theory is straight up bs, as will every other microtubule researchers will when asked.
@@leejuicy Any specific critiques of the theory? There are actually quite a few people who support it. I'm not asking for a super in-depth explanation, just a little more than the typical "I study it so I know what I'm talking about" argument.
@@ericpowell96 1. many MT-associated proteins and MT-modifying enzymes, which are central modulators in orch-or theory, are often dispensable for neuronal function. A good example is tubulin acetyltransferase MEC-17, where its loss-of-function phenotypes are limited to mechanosensation, despite acetylated tubulin being the predominant form of axonal MTs. Similarly, loss of many MAPs don't show overt behavioral phenotypes in model organisms.
2. Computer simulations of C elegans brain, the only animal so far to have every synaptic connections mapped, faithfully recapitulates its behavior. This simulation does not take account of any quantum effects, strongly arguing that quantum effects are unnecessary for the function of C elegans brain. Structures of MT and neurons are largely conserved between C elegans and humans, suggesting that qunatum effects are unlikely to play a central role in human behavior.

Sadly rotifers have a short life span.. I miss the humourous anecdotes
(They left a comment on the recent livestream! #NotAStalker)
Yeah, those papers were entertaining until Disney made the sequels.
Don't recall seeing animation in previous video, seems a little out of place.
I think the brownian motion video had some.

Virus structures are exponentially smaller than the smallest microorganisms. They require ridiculously powerful electron microscopes
@@purplepowerranger23 Yeah, they'd also need to get their hands on the virus, which while probably not difficult.... (Though I guess they could just use any old coronavirus.)
