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!
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.
"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.

I love how fascinating and unique these videos are. Not every UA-cam channel gives you vivid mental images of a heliozoan riding a golden chariot in the sky.
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?
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.
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!
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
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?
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!
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?
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
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..
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.
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). (ua-cam.com/video/5rqbmLiSkpk/v-deo.html for instance)
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.
@@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.)

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

Some heliozoans have a silica shell, it could be that.

Nice footage.
What is the microscope you use?
pretty badass little creatures actually
They make me think of the "tanks" in the kraken wakes, I assume they may have been a direct inspiration.
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.
You should have added magnification scale to 0:37

Harry Potter & The effect of low temperature on these structures in the formation and maintenance of axopodia
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.
Microtubules are basically carbon nanotubes.
I wonder if we could use those organisms to create massive amounts of them for us.
Do they eat each other?
One heliozoon, two or more heliozoa. Something that belongs to a heliozoon is heliozoan.
