- Death is inevitable and mysterious, even in the microcosmos. Stentors, heliozoans, and yes, even tardigrades, experience death in many different ways.

Imagine if your death made you briefly famous among thousands of creatures of unimaginable size and intelligence, and of whose existence you never knew.
Comments like this are why i read the comments section. Bravo!

Omg I can only imagine a bigger creature recording and studying a guy getting groceries like.
“Here we see a creature just going along, collecting food, minding its own business, but as you watch it falls over and starts to shake. Other organisms notice this and one even intervenes. Setting the shaking organism to its side and seeming to communicate something to the others. Later on more organisms show up to help and eventually the original one stops shaking. We’ve never seen anything like this before and we’re not sure what caused this one to start this act in the first place or even if it was intentional, but we do get to watch the process of these beings working together just to help an individual. Perhaps we’re not as different as we thought we were”
Damn, now I want to read a sci-fi about that scenario. xD It would also make me feel a little better about the end, I think.
MayTheGamer 12 “here we see another organism, in it’s natural habitat. It rarely leaves, and it only does so to procure food or water.”
Imagine if you died your skin just burst open and leaks muscle and blood and organs everywhere
But then reassembled back again.
It was popular in Japan.
Except that's what happens. Your belly swells and your intestines rot away creating this gas that inflates you until you burst open and let the world see what's left of your dead carcass.
I can't die. Immortal.
@@estebancardoso8733 Yeah, but that's some time _after_ you die. It's one thing if you burst open when you're already dead, it's a whole other when you die because your skin just popped open somewhere and everything slid out of you all at once, still twitching and moving and writhing in a desperate but feeble attempt to stay alive, all because of something asinine like "it was too hot outside for skin to stay hydrated" or something similarly scientific but vague.
It doesn't help that, apparently, some cells can actually survive this by just... _sliding it all back in_ if they're really lucky.
When I was in grad school (neurobiology, in the zoology department), I had intracellular electrodes recording the electrical activity of a single nerve cell and outputting to a speaker. After my protocol was done, I decided to listen to the cell die, instead of just cleaning my bench and move on. For about 40 minutes, I heard that cell's activity get more and more irregular and disordered, until it finally fell silent.
a little bit late, but, can you share? Love to hear that
that's really interesting
(undergoes lysis) Mr. Hank I don't feel so good.....
Mr Green
This is so sad Alexa play deathpasito.
@@eyed3448 Tony Stank
*snap*
😆 lol, Was just about to make the same comment.
It actually made me a little sad seeing that cell die. It almost looked like it was trying to stay alive.
Instead of Divide, and Conquer , it was, Divide, and die.
@@Geoffr524 Sorry to be pedantic Geoff but I think you meant 'conquer.' Concur means to agree with. I do hope you 'concur' with me. 😉
I saw on another channel, no narration apart from text explaining what was happening and an Amoeba was trying to eat a pair of Stentors. The battle went on for quite some time, one Stentor escaped unharmed and the second was fighting to escape as the Amoeba was trying to engulf it. Eventually the Stentor tried to divide itself and have a small part escape and the Amoeba wanted it all.
Eventually about a quarter of the Stentor escaped.
It was like it split hoping half of it would survive, but it didn’t work. Nice try though.
It didn't almost look like it. It was trying to stay alive.
I'm still having a hard time wrapping my head around the fact that some single-cell organisms are much larger than the majority of the multi-cellular creatures.
Hank! I think just found an human head sized Amoeba!
@@jerrygu5316 It's got multiple nuclei! It's cheating!
@@jerrygu5316 I've got a paramecium the size of a labradoodle. It's pretty freaky smelling.
Did you use a password generator to generate your username?
@@TheFox517 I used some random hash generator of random length. This was dozens of years ago when I couldn't think up a name that wasn't taken. It sticks out like a sore thumb - that's the opposite of my original intention.
The mystery cell's mystery death was sad, but I also found it... sort of terrifying. Sometimes watching something in it's simplest context can provide a certain clarity: watching this living thing stop being living, it's guts spilling outside it's body, it's last convulsions as the molecular mechanisms of self-maintenance try and fail to fix the problem - it makes me think of how we really are the same, just more.
As I write this countless cells are dying in me, quite similarly to what I just saw, and at the same time others are being made to replace them. We're all rotting and growing in a great chain-reaction of processes and counter-processes, for as long as our molecular mechanisms of self-maintenance can keep up, until the rot finally outweighs the growth.
There really aren't any sharp edges in life; only gradients from a distance.
Could you do a vid specifically about the common type of organisms you'd find on the outside of a human body? I wanna see the lil guys hanging out on my skin/eyes/hair/etc.

our microbiom contains of millions of unknown species
This would be incredible!
The life of our life. The microbes we owe our existence too.
Yikes!
The inhabitants of this planet "Me" 😎
Wow. The way the cell membrane seemingly reassembles at the end before suddenly bursting is really fascinating. Poor lil dude. Thanks for sharing, guys!
One last try...
I like how Hank narrated this channel with very different style compared to SciShow
I didnt even thought it's Hank the first time I listened to him here
The lilting voiceover goes really well with the imagery and backing sounds.
ASMR
@@precumming N O
@@precumming yeah, no, NO.
The lacyrmaria is creepy wtf. You saw it poking OUT of the slide??
Lacramaria Olor is awesome, and there are lots of great videos of them terrorizing the local environment.
Tying videos together...part of how that little head at the end moves is little bands of cilia. There pushing and pulling going on!
That is a thing to search for food
that's how horror sci-fi movies start...o.0
damn that long tentacle just impaling everyone left and right
Its a zerg crawler
I adore this channel.
Wtf ShoddyCast, so little comments and likes. Here before, by any chance, this comment blows up
Me too!!
Same
Shoddy! Are ya still making videos?
Only god can be adored !! 🤲🤲
Best content on RUclips, hands down.
If you like this channel check out the channel "ibiology" if you haven't already.
Idk have you seen those unboxing videos?
I feel this is the best microbe channel. You should also watch Petrolicious if you're into cars.
@@ominous-omnipresent-they I feel like this is the best microbe channel. Now go to my channel so I can make more money!
If you like this, go to iBiology and sit through a few of their lectures. My whole world has changed with that channel.
I love how you refine our childlike curiosity for our reality that has always been within us
Perfectly summarised.
I am growing bacterias in glass cup, I watch sometimes there and understand what a big game is going on in it, some species extinct, hunters for hunters, everybody tries to survive.
Yes!

“It is only ever in the mysteries that knowledge is able to be found.”
It is known
UltimateKyuubiFox
Sounds incredibly deep, but is incredibly shallow. It's identical to stating: "You can only gain knowledge about something not yet fully understood". Quacks often use tsuch kind of mythological phrasing to sell their obscure antiscientific bullshit. For the same reason, scientists usually refrain from using it.
Frank Schneider It’s... literally a quote from Hank in this video.
UltimateKyuubiFox
Yes I know, but just because he talks metaphysical nonsense, doesn't make it true.
@@frankschneider6156 macrophage is gay
..............is it weird that i want hank to speak at my funeral like this
calmly, quietly, clinically yet also with sympathy
Just a matter of how big of a patreon you are. And if you are a BIG enough patreon of his channels, his sorrow and sadness will also be very sincere.
@@frankschneider6156 lololol
Judging by the way that he evaporated into nothing, I’d say this has something to do with *Micro Thanos*
There is probably a micro Thanos everytime you wash your hands

i dont see any thanites
Hank doesn't sound so happy this episode, awww.
I'm not happy either ):
Death everywhere...
Whos hank? The narrator?
@@sauviel6296 Yeah
Lacrymaria olor's extension was crazy just slicing that larger organism like that
The Paradileptus died due to an endoparasite. At first the tip looks like it's part of the Paradileptus itself, but you can see that little stick like portion is still moving around after the Paradileptus lyses. I guess it was like a "chest-burster" moment, when the parasite pierced its membrane to escape, the Paradileptus was done.
Wonderful content! One little thing though, I never really stop to think how big "200x" magnification is, if I see a measure of length I think it would be much more intuitive to think how big the thing you're looking at is. Just a little line under or next to the magnification that shows the length of for example 1mm or 100μm. Either way, love this series!
@Yevhenii Diomidov I would agree that a unit of length would be interesting, but I don't think it really matters what screen it's portrayed on since 200x just indicates the magnification of the microscope, you're not going to be able to get a 400x focused image out of that on a different screen.
Cut out some strips of paper to signify a millimetre at the popular magnifications. You'll probably have to contact James on Twitter to get info on how the video and your screen compares to his view.
Yeah, like a map scale, in the corner of the video. As far as magnification, it is true, that you would want, to view on a larger screen, than a phone screen, especially, for older eyes, like mine.
@Yevhenii Diomidov dude your comment is pure retardation, since 200x is the microscope magnification, is not a zoom in video or picture, so it doesnt matter in which device you watch the video.
@@mmtruooao8377 It's not about focus, it's that you can't know what scale you're looking at only knowing the magnification. Intuitively you'd want to do 1mm(on your screen)/magnification = actual size. If you have different screen sizes that will give different results of course. So I guess I was wrong too since this is what I was thinking at first, but seems the magnification really is a useless measure because there are no reference objects we can compare it to.
Ciliate: **undergoes lysis**
Also ciliate: change da world, my final message, goodbye
I rate this a “surprisingly-heartbreaking/10”.
Screw tardigrades, Lacrymaria is my new favourite microscopic badass gangsta. I can't believe that cytoskeleton is able to do something like this.
Also, the way that after lysis the dying cell somehow manages to come back together for a while is interesting. I wonder if it was an event like this how cellular division could have evolved long time ago.
I think everyone ends up nerding out over Lacramaria, Dileptus, or Euplotes. It seems like each has a bunch of people who just squee about them. :)
Wait until we get to amoebas in chainmail!
I don't know why I feel so sad after watching this video.....that second mysterious struggle to stabilize life....albeit momentarily. Death......oh that most debilitating part of life.

I think that response speaks deeply about the human capacity for empathy.
It is in this death we see our own death
Me too...after four or five rewiews
Well Hank, you did it. You made the best channel on RUclips.
The chemistry of it all really shows when the innards of one microbe triggers the death of other microbes it touches. A single touch with a certain molecule and the entire complicated system of a cell falls apart. It makes me appreciate my skin a lot more
The only thing I'll click on so fast is an Eons upload. This is some of the best content on RUclips.
I feel like they're doing what the Discovery channel used to do - pursue scientific topics for the joy of knowing and learning. I missed this kind of content so much in my media!
This is my favourite RUclips channel now. Love you uncle Hank
And Love you... my guy Hank, I could be your mother, maybe your grandmother!!! GO ON on your channel with the other nice hosts!
My opinion this is up there with Werner Herzog, and David Attenborough.
Rest in peace little mystery buddy 😭
What about the poor green cell. He was just minding his own business and died for seemingly no reason when the paradileptus died.
This is the best series on RUclips at the moment. Thank you so much for your hard work in writing these videos and getting this footage! It's wonderful to find a new appreciation for microbiology.
I think it'd be awesome if this channel started a series of the micro universe inside our own bodies, and how it all works together.
would be cool but probably really hard to film though lol
Surely one of the most interesting, and calming channels on RUclips
4:53 -- Dunno why, but the way it just kinda 'pops' and dissolves fascinates the hell out of me.
Yeah it popped like a soap bubble, makes you think about how fragile the membrane actually is
Damn I'm just addicted to watching these. The narration, the music, the subtle movements of the cells in their environment.
All of it is just so alien! I love it man, don't ever stop making these kinda videos. They're educational and entertaining,
Growing up bio was always a personal interest of mine.
But it was always presented in such a dry and boring way.
This is exactly the kinda educational content we should be teaching with! 💎
I've never opened a video faster in my life!
Love the new channel, binged all the “older” videos yesterday.
Such a calm, soothing voice, compared to some of the other channels :-) Keep up the good work !
After an astonishing and hectic ten days - getting ready for, traveling to (and from), and most of all attending (or maybe enduring) DragonCon...
It's so, so nice to be home again and to listen to Calm Hank.
The cell dying may be mysterious but there's a strange harmony to it, to my eyes. A sense of "but of course," inevitability and sadness, but also an ephemeral rightness. As if, in a way, the creature is just - letting go at last. A very final relaxation, releasing one's grip on life, with neither a bang nor a whimper - just a silent sigh.
Once again, wonderful images, and a fascinating script - thank you both so very much for making this series.
*Screams microscopically*
ah.
These are the videos that make me put down whatever I'm doing, and watch them.

The content in this video is the most fascinating, interesting and informative I have ever witnessed. It has answered many of my questions I've pondered for a long time. Thank you for creating the video and posting it.
Great video! Very nicely narrated, smooth and unrushed, and very informative, you really did take me on a journey through the microcosmos. And excellent footage of course from "Jam's germs", his footage was always good but got even better when he upgraded his microscope.
Actually one of my favorite channels on youtube. I love these unknown, unexplored fields of science!
While I believe that all sciences are still filled with many mysteries (it's what I love about the sciences) I don't think it fair of you to think of microbiology as unknown or unexplored. Far from it as it has long been the focus of lots and lots of great science. There was a time when I fancied it as it is close as I would ever get to exploring an alien world. In the end, however, I picked marine studies as the oceans are also alien worlds to us and one can visit them in a more tactile way.
NonExistingName
Microbiology is far from unknown or unexplored. It's actually one of the oldest systematic natural sciences, starting more or less immediately after the invention of the microscope (1650 or so)
Like many, I'm just here to say great content ! Beautiful pictures and superb narration.
I think this is my favorite channel here.
Keep up the good work !
I watch this channel all the time! I love it! But I watch on my TV so this is an extra effort on my part to leave a comment to say this channel has changed how I feel about life. It is way more miraculous than I thought. THANK YOU SO MUCH !!!!
Thanks for making this channel hank. Its amazing. Im sure youll never run out of information on the microcosmos.
Tardigrade: "The humans say I'm immortal."
Vorticella: "Is that a challenge?"
4:50 looks like what happens when you use the "kill" console command on an Elder Scrolls Game
This is my first time at the channel and each video is a treasure. I have never imagine how much similar micro organism looks like the human being. They eat (even more than they really need), reproduce and die too. And its pretty Amazing watch all the kinds of death, killed, diseases, and natural causes.
Greatings from Peru and sorry for my english
I love this channel. Everything about it... Thank you so much for taking the time to give us little people a grand look inside of this amazing place we all know as life.
*A thousand THANK YOUs!!!!!

Stop.
This is the only youtube channel where I stop everything and focus only on the video. It captures me and sooths away the chaos of my life. Thanks for making this.
Thank you for listening to our feedback on missing things on the screen sometimes and providing with the attention catching circle. Very useful and tasteful!
AH! I was doing homework and I didn’t see the upload!
It's crazy how complex these cells can be even though they are so small. The cell walls are only a few atoms thick aren't they?
Cell walls are much, much larger than atoms though. Atoms are on a whole different scale.
A few molecules thick, but they're pretty large molecules.
Not exactly what you asked, but you should be aware that only some cells have cell walls, but all cells have membranes, so cells with a cell wall will also be surrounded by a membrane, adding to the general thickness of their envelope
It's a phospholipid bilayer which is consists of two phospholipid molecules that are pretty big on their own.
Great stuff as ever James, Hank and Andrew. One of the best channels on RUclips ever... Keep up The Great Work.
New content from this channel is now what I look forward to every week!
Don’t you hate it when your notification arrives a couple seconds late?
I don't feel so good

"Death by proximity" seems like a really scary cause of death
This is one of the more polarizing videos I’ve seen in a while. I think about it all the time, and it’s so wickedly gripping.
I never expected death to look so beautiful! Thank you for your wonderful channel
Yea its beautifull couse you are not the one exploding XD
#Ale Dro Nice one! XD
If I was the one exploding I don't think I'll feel anything anyway...But you're right, who knows! Or are you implying that it'll look gross? As contrasting with this beauty... still there will be millions of cells that'll die beautifully in me u_u
Can't not watch a notification of this channel
I love this series! Thank you for exposing more of the beauty of nature.
This is definitely my favorite science channel right now.
I watched this on my cell phone then on my 43" television. The microbes were definitely much larger on the television, but in both cases, it said 200x

It's like life within life makes me think of the movie Horton here's a who
Well, this episode will set John off.
So glad I found this. Watched a few episodes and on 3rd realized who the voice is haha! Subscribed and sharing these vids around. This stuff is SUPER interesting, I can't get over how amazing the tiny stuff is around/on/in us is.
I'm loving this channel so much
The only thing better I could hope for is if you guys uploaded these in 4k
some of the most relaxing death i have ever experienced
There's a 'Micro Murder Mysteries' channel idea in here somewhere.
This channel is blowing my mind. Every episode is just amazing!
Great content as usual
I just picked this video instead of a dota gameplay. Not many channels do that
You'll find yourself doing it more and more
This is wonderful content and a very fitting homage to Carl Sagan. Hank, you do a great job capturing both the softness in Sagan´s voice from the original series as well as the joy there is in understanding a little more about the world around us. Bravo.
Love this channel!!! Love all of your channels!!!
I love this channel already. Thank you for uploading high quality microscopy video.
Can't get enough of this stuff. Thank you.
omg there is no video other then this about micro organism. Thank you for sharing this!
my favourite new channel. keep it up. blows my mind this stuff can exist like it does while being so tiny
Awesome! I love these, keep it up!
Amazing. :) As always: amazing videos.
This is fast becoming my favourite youtube channel. And I absolutely love the narrators voice - great work :)
This is so poetic. Great job y’all!
This is a fantastic series, thank you!
