This makes me feel hopelessly large and ignorant of a whole story of cells and their lives as they live, die, and repeat, while I compare myself to the size of the universe and feel small, part of me wishes I was much smaller, and yet thankful I am not.
Okay, well keep in mind, there is no perspective of the universe that allows you to see the universe. Even out side the universe you would be blind to the inner workings at the center by the dense layers and ever changing scenes. Your position is as good as anything.
Hey Hank (and John), could you please ask James which microscope the first one was the he used in the beginning? Which 170$ used ebay microscope did he get? Thanks for doing all the great content you two do and congratulations to all your success!
She could very well be right. Maybe apoptosis genes were triggered in the first one which made caspases that it leaked out and the other cell swam into them. Very plausible!
I think the fact that the death of these unicellular deaths feel so viscerally violent says something about your amazing cinematography and story telling. I felt myself physically recoil at the death of a brainless organism. That’s amazing.
Thank you, Hank, James, everyone on the Journey to the Microcosmos team. Thank you for the chance to think about something other than the different, smaller, scarier part of the microcosmos that has been so limiting our lives and making us confront the fragility of our own survival for a little while. Thank you for leaving us with hope and a little more knowledge than we had a few minutes before. Never underestimate what you are giving us. Thank you.
I'm glad I found this channel, as my major is hopefully going into stuff like Microbiology (Technical name is AS Biology with Cell/Molecular emphasis) This is just...the kind of stuff I wanna do. Look at all the little things, observe...although I know there's a lot of paperwork involved as well.
It's so interesting. I've been obsessed with understanding the cosmos since I was a young kid. You have reminded me there's a whole other world in the Microcosmos.
I love that last kind of ciliate! They have many cilia fused into much bigger ones, and sometimes they seem to walk along the bottom of the cover glass like tiny tentacle feet.
I suppose you could compare it to a disemboweled person dancing around till all their innards moved back in place and their wound healed over! I'm quite amazed.
4:00 it’s A similar process To The necrosis processes that do happen in animal organisms, mostly activated via caspases which are liberated from dying mytochomdriae and are calcium dependant and tend To expand as a biochemical phenomenon trough a calcium disbalance in healthy cells through a massive calcium liberation when a dead necrotic cell liberates a whole lot of calcium when dies, enough for a neighbor one To just can’t manage that overwhelm in calcium osmolarity To maintain it’s owns’ mytochondriae going on
"The kindly voice of an elderly narrator..." Not sure whether you're referring to my naturalist documentary hero, Sir David Attenborough, or to my secondary one, Marlin Perkins ( _Mutual of Omaha's Wild Kingdom_ ), but either way, you get all my love for that line.
@3:29 I watched a ciliate die in a similar manner once. It was more rapid as well as explosive, its organelles spiraling out into the void. As I was tripping hard on lsd at the time the death of this microbe that I had been observing (I named it Cecil) was soul crushing. I yelled "Cecil, you had so much to live for!" My roommate asked me "Who the heck is Cecil?" "One of the ciliates that used to live with us." One of the magnificent aspects of microscopy is how such a tiny sliver of our own universe becomes your entire visual world; the dichotomy of looking at the drop of pond water as I place it on a slide and then experiencing it as an ocean through the microscope. You also mention the phenomenon of a healthy microbe dying after it encounters the fresh corpse of another. I've wondered if it is lysosomes from the deceased encountering and damaging the membrane of the healthy cell.
I love your videos. I’m not a teacher, I’m not even a scientist, or anything. I’m a 19 year old electrician 😂. I just have an interest in the micro cosmos, space, time, math, language, conspiracies, and just the way the universe works. People think I’m some sort of genius for it but I just have a natural curiosity and find excitement and interest in everything. Goes to show how cool science is I guess 🤙🏻
We are a lot who have been this early to these videos, flocking around it as predators! Our human response to corona virus seems oddly similar to what we saw in your video. And thank you once again for this beautiful footage and soothing speak, and of course to all of the people who made this possible! 💚
I really loved the beginning! Amazig corelation with macro world. We should always remember the microcosmos can be as much interesting as the being we see with our naked eyes.
Unless there's a specific reason to become large and macroscopic, life will always prefer to be microscopic and small. That is why the vast majority of lifeforms will be microscopic, with macroscopic life being an extremely rare exception to the rule. That is my solution to Fermi's paradox.
Still, on one planet known of has a percentage of multicellular life that has even reached mega fauna in dimensions. Life thrives where it can and ekes along where the going is tough to nearly impossible. Out of all the trillions and trillions of stars in our galaxy, billions of those have solar systems. Millions of those planets are earthlike, and in favorable zones for life. Earth is just one planet, with a long history of outlandish life forms. Multiply that × millions and do the math. (I'm low balling like hell on my numbers. There are countless stars in this galaxy, and countless galaxies in the Universe.) I think the answer to Fermi's Paradox is distance.
3:52 It may be that Ciliate's membraine is being stretched and ripped apart at the moment by some kind of changes in surface tention or molecular adhesion.
Few questions: 1. Under the microscope, how much of the z-axis do we see (besides the x-y plane)? What's the DOF that we are dealing with? 2. How thick is the typical z-axis when samples are prepared? 3. So far all the movement we see is left-right up-down, all we learn in school and see everywhere is that the "microcosmos" world is "flat"; how different do the organisms react/move when it's in the "real" world (where z-axis is "infinite") vs on the limited depth of the samples that we are viewing? 4. Do micro organism even care about 3D space, or everything to them is 2D-ish. 5. Any technology available to have a more 3D representation of the microcosmos?
I'm not a microbiologist whatsoever, but maybe the first organism has some protein or chemical signal floating around inside that rips things apart, like a "self-destruct" command.
The mystery of the contagious death could be an enzyme that is released to dissolve the membrane and even the dilute remnants cascade a reaction in the living nearby.
In regards to the contagious death, I would recommend checking the temperature of the fluids in that region. Another thing you might want to check is the acidity
Hank, your voice is so soothing, even while hearing you describe the vicious death of microorganisms. I enjoy Journey To The Microcosmos 10x more than SciShow.
As to why the second *Cilliate* self-destructed, I'd suggest it was caused by a specific type of *_Messenger Molecule_* called a *Apoptotic Cytokine.* *Cytokines* are *_Signalling Molecules_* found in multicellular organisms (including humans) that are usually used to communicate between cells, but under rare circumstances can also be used by a cell on itself, in a form of communication called *Autocrine Signalling.* In it a *Ligand* (or molecule which triggers a specific *Receptor* ) is released from within the cell which attaches to a specific *Receptor* on the external cell wall, triggering it. One of the things cells can do is self-destruct: often due to severe damage, infection by a pathogen, or an identified internal defect. This is called *Apoptosis.* Unfortunately, when a cell is in severe distress, what can also happen (& I suspect is happening here) is enough of these *Apoptotic Cytokines* get released that it can trigger the effect on healthy neighboring cells. While *Cilliates* are only single celled organisms, they must still have ways to communicate with other members of their species (recognising another *Cilliate* & not trying to eat it, for example) & they have *Chemical Receptors* on their surface which are triggered by *Ligands* that may indicate either food, or a threat. When your only senses are that of *_"Smell/Taste"_* & perhaps *_Touch +_* (no Vision or Hearing), then there are going to be intense evolutionary pressures to get really good at them. + They certainly don't perceive touch the sophisticated way that we do, anyway.
Heres a very wild theory abaut that bursting ciliate: The porpuse of this reaction caused by another dead ciliate was distracting a potential predator that might have eaten this ciliate (just like the lizards tail but here its not caused by predator itself but rather by the remains of the potential predators meal)
3:36 are scientists still clueless as to why organisms die when they get close to other dead organisms? much like crabs, when a crab dies every crab around it dies too (presuming the first crab death releases ammonia or some other type of chemical that triggers a chain reaction killing all surrounding crabs in the area too)
its so weird clicking on a video for a channel this big and when you get there it has only 7 views but has 11 likes (I got here when I got the notification, but I'm not going to watch it until my mom gets home with supper, cause I enjoy watching these while I eat)
Today you showed us, that surviving each day, even each hour is a hard task in the microcosmos. This leads to the next topic: How fast and actually how do most of the microorganisms (especially the multi-cellular, where mitosis is not enough) reproduce? Have some organisms even some states of age, like growing up and adults ready to reproduce again?
Andre Lin, rotifers can actually move quickly if they need to. Amoebae are slow but steady. I’ve seen video of a large amoeba slowly engulfing a pair of resting paramecia, which don’t recognize the threat until they’re completely surrounded, and then they freak out.
This video was the one to make the realization of the 3 dimensional shapes these animals actually have that we just cant see exists bcus of the moments theyd turn upwards and stuff (i already knew but, it was a different level of reality hitting me )
Hank I feel you are a good person and I offer my opinion with respect for you and all the other viewers of this channel. For me, this video illustrates where humanity has lost humility. Experimenting on and eliminating what we perceive as a lower life form feels troubling. Can you think of other times in recent history where this has taken place? Before you say I am being dramatic please pause; the principle is exactly the same: humans act in ways that are unnecessary and careless because we think we ‘need’ to know about why things happen. Sometimes we do. Sometimes knowledge and discovery keeps us alive and sometimes actions are taken because that principle gets warped with a greed for fulfilled curiosity and we think we ‘deserve’ to know the why of something. We then take actions simply because we can, observing the death of an organism for example. Based on comments here you have multitudes of company forming an audience entertained by life, consumption and death which makes me incredibly sad and this is a group in which I do not belong. Thank you for letting me respectfully post my thoughts and feelings and I wish you well.
This makes me feel hopelessly large and ignorant of a whole story of cells and their lives as they live, die, and repeat, while I compare myself to the size of the universe and feel small, part of me wishes I was much smaller, and yet thankful I am not.
Okay, well keep in mind, there is no perspective of the universe that allows you to see the universe. Even out side the universe you would be blind to the inner workings at the center by the dense layers and ever changing scenes. Your position is as good as anything.

Thank you
Very much
I get annoyed when people try to act all superior by talk of "tha *vastness* of the cosmos"
imagine if a person goes for a ice bath and then goes a to a sauna and then explodes
XD
We would have to be single cell lol
there are family stories of a great-uncle who died of heatshock from that! cells exploding
DONT SAY THAT
The microscopic world is full of wonderful and fascinating things. I'm glad a major youtuber finally put them on the spotlight.
I feel exactly the same. I'd been waiting for something like this channel for a long time.

*How to Survive the Microcosmos:*
*Step 1. Become as Rotifer*

My youngest daughter suspects a 'self destruct' enzyme in the spilled cytoplasm.
I suspect she'll be explaining my taxes to me by age 14.

She'll be writing the next tax code by age 18
She could very well be right. Maybe apoptosis genes were triggered in the first one which made caspases that it leaked out and the other cell swam into them. Very plausible!
that happened.

Poisoned harpoons might be more generally applicable than just in the microcosmos.
Wow these videos are just wow. Narration is amazing! Thank you for making and plz keep uploading.
3:41 Is it possible that the original cell's lysosomes ruptured and their contents lysed open the passing cell?
Lysosomal enzymes are mostly active in acidic ph, so that is not very likely as ruptured lysosomal enzymes would not be very active.
maybe because of caspases?
This episode has been amazing. Thank you guys for your job, thanks to al the patreons who allow us to enjoy such a great show!
that ciliate healing is so god damn cool, and an EXCELLENT sight to finish on.
I suppose you could compare it to a disemboweled person dancing around till all their innards moved back in place and their wound healed over! I'm quite amazed.
This was great like every one of them you guys do but this one had me especially glued to the screen thank you
Congratulations guys! For sure one of the best material I have ever seen on your channel!

The pictures in the textbook don't show the floaty motions of the microbes.

"The ciliate has survived this day." * rinses slide off in the sink *
You channel has introduced me to a brilliant world of life I had not known to exist. This inspires me to get a microscope of my own.
As to why the second *Cilliate* self-destructed, I'd suggest it was caused by a specific type of *_Messenger Molecule_* called a *Apoptotic Cytokine.*

It always amazed me how such a slow-moving amoeba or rotifer could capture the ciliates zipping around it.
Andre Lin, rotifers can actually move quickly if they need to. Amoebae are slow but steady. I’ve seen video of a large amoeba slowly engulfing a pair of resting paramecia, which don’t recognize the threat until they’re completely surrounded, and then they freak out.
The rotifer is sucking them in like a vaccuum cleaner.
bro nice voice :P and thanks , super interesting visuals
I heard that Sarracenia and nepenthes have miniature ecosystems in their pools of digestive fluids.
Ever watch Crime Pays but Botany Doesn't? You might like.
Wonder if you guys could get David Attenborough

. That would be really cool.
Can you recommend a book on how to do this kind of work? Preparing slides and observing microscopic life.
