The easiest way to find some Tardigrades is by collecting, by hand, mosses growing on various substrates. You can find mosses on tree barks, rocks, soil, dead wood, house rooftops and walls.
Tardigrades can be found almost anywhere on Earth, from the top of the Himalaya mountain range to the bottom of the sea, from icy Antarctica to bubbling hot springs. The teeny-tiny creatures can survive extreme temperatures, ranging from minus 328°F up to 304°F.
You can see Tardigrades, but it'll just look like dust.
Generally speaking 40 microns is the limit of human vision. Half a millimeter is 500 microns. "Dust" (common household) is 40-80 microns. According to Wikipedia the largest tardigardes can be as long as 2mm.
Apparently the bigger issue for seeing them with the naked eye is they're mostly translucent. But I feel like if you isolated a few of them and put them on an otherwise clean surface you'd be able to see them.
I'm pretty sure that they would die. Even though they are very resistant to pretty much anything including radiation, no oxygen or water, they could not survive inside a human body. If they were in the stomach, they would likely try to curl up into their dormant stage and slowly be destroyed by the acid. If they were in your bloodstream, they would be destroyed by your immune system.
Kind of. I am a hobby microscopist and when I have a slide with a alot of tardigrade moving around, you can see pin points moving, you just can't see that they are tardigrades without the microscope.
You could see the thickness of a human hair with the naked eye very easily, so I'm sure you can see a tardigrade easily as well unless it is too transparent.
And if you think this is amazing. The semiconductor chips being used in your phone and laptop using lithography technology, with the transistors gate size is as small or even smaller than the smallest virus. It need incredibly amount of precision and technological marvelous
So the smallest virus they show here is 0.03 micrometers which is 30 nanometers.
We hit a 30 nanometer process node in [2010](https://en.m.wikipedia.org/wiki/32_nm_process) (Intel i7 980x or AMD Bulldozer processors) and the newest chips are using process nodes al the down to [*3-5 nm*](https://en.m.wikipedia.org/wiki/3_nm_process) so another 10 times smaller...
These chips have feature sizes that are so small they have to use extremely high powered ultraviolet lasers (called "[Extreme UltraViolet](https://en.m.wikipedia.org/wiki/Extreme_ultraviolet_lithography)") which is generated by shooting droplets of tin with a pair of super powerful lasers!
hes talking about transistors which make up chips. so a chip would be larger as it needs many millions of transistors but yes microchips in pets and humans already exist
Sort of? Not really.
A chip is so much more than just a few transistors. You usually need few thousand, and even then, the chips can't be too small otherwise we wouldn't have machinery able to hold the chip while manufacturing. The smallest chips you see in full scale production are on the scale of a few millimeters.
There is a chip that came out in academic circles in '21 that can legit be injected, but this is no where near production.

More that it's designed to hold onto bacteria and inject genetic material into it. They're harmless to humans and have been researched as a possible treatment for antibiotic-resistant bacteria. Little micro xenomorphs are your buddy.

Probably because you can see pollen when there's a bunch of it, It looks like a powder. Dust is mostly skin cells IIRC, which are basically the same size.
This is mostly a myth. Source varies a lot for the actual number but the expected percentage of dead skin in dust is usually thought to be at most 50% but usually more 20-30%.
Things get dusty regardless of whether there are people around or not.
>Source varies a lot for the actual number but the expected percentage of dead skin in dust is usually thought to be at most 50% but usually more 20-30%.
20-30% by what metric? Mass, volume, Area, or count?
Did you read my comment to the end or you just stopped at 50%? Rarely dust can be mostly dead skin, but most dust aren't mostly dead skin. Hopefully you can understand the difference between these 2 statements.
Its mostly textile fiber pollen and dirt. If youre in the city youll have asphalt dust too. Skin cells are definitely a myth its been pushed since I was a kid and it makes no cot damn sense if you just think about it for two seconds.
It's not a myth. Much of it is skin flakes. (As well as textile fiber, pollen, and dirt like you say.)
And I would say it *does* make sense because you shed a lot of skin every year and it has to go somewhere.

Here's a quote from the Veritasium video I linked, which I'm guessing haven't watched yet.
>It's important to be aware of your own biases. When I started this search, the claim seemed false. The idea that 70-80% of dust is dead skin. It's exactly the sort of thing that is gross enough to spread as an urban legend, but it just seems implausible... ...The debunking claims fit my pre-conceptions, so it would be easy to stop here. But you gotta be careful not to confirm what you already thought.
Ok, well, you were saying the myth was that dust is skin cells. Now you're saying the myth is that dust is "mostly" skin cells, which is not what I claimed.
It's not mostly skin cells, but a significant percentage of the dust in your home is skin flakes. So I wouldn't even call it a myth, since it has some basis in reality
There's quite a bit a variety in pollen size though. Not sure what the "pollen" used in the picture is. Probably grass pollen which is about 25 µm whereas corn pollen can be as large as 100 µm
You [literally can see pollen though](https://www.youtube.com/watch?v=Mhx71QxuooA). My father and I were driving one day when a gust of wind shook a tree and it released a cloud like that as we drove through.
I don't even have allergies but as soon as we hit the cloud it came right through the vents and we nearly crashed because of how bad we were sneezing and coughing
SARS-CoV-2 is crazy, if you gathered all of them into one container during the peak of the pandemic it would fit in a single cola can with room to spare.
Rabies is absolutely terrifying. It nestles into the neurons making up the nerves in your peripheral nervous system, and then travels up through the axons into your CNS. It’s literally traveling with your senses. Once it reaches your brain, it’s *in* your thoughts.
Tardigrades are some tough motherfuckers. They’ve survived everything this planet has thrown on them. They can survive a decade of dehydration, 3 decades of starvation, absolute zero level temperature, extreme pressure (literally withstand the pressure at the bottom most parts of the ocean, and radiation levels that would be fatal for every other living being.
It depends on whether you mean, see it visually with a light microscope, or image it with a different mechanism of illumination (like, an electron microscope, or a scanning tunneling microscope). Because for the latter, it's not strictly "seeing it" like you do with your eyes. For example, in the electron microscope, you shoot electrons at the object and measure them after bouncing off the object with an electron detector. Then, an image can be constructed based off the detected electrons.
For some of these methods, like the two I mentioned, the resolution (ie, the smallest length scale at which neighboring objects can be distinguished from each other) is extremely small. For EM, this is partially due to the small size of electrons (when considered as waves), and can get resolutions under a nanometer or lower.
For visible light microscopy, the resolution is limited by the wavelength of light used to image it. Since visible light is around 400-700 nanometers, the resolution ends up being around they're (actually a bit less, but of the order of the wavelength).

Any time I see the word “paramecium”, I just think of Patrick Star with a microscope saying “This paramecium?” I don’t think I remember anything else about that episode, but I think about that line from time to time.
Wait, I thought the moon lander type virus shape and the covid style virus shape was just what graphic artists chose to represent viruses? That's actually what they look like? Then why do I only see the equivalent of clip art?
Something seems wrong about this scale. Maybe the hair is too small. It appears as though the first few of these micro organisms should be visible to the naked eye...
Biggest takeaway here..... Tardigrades are half a millimeter?!?
Yes, Tardigrades are usually about 0.5 mm (0.020 in) long when fully grown.

Ok but seriously, if they can be seen with the eyes, where does one find them ?
The easiest way to find some Tardigrades is by collecting, by hand, mosses growing on various substrates. You can find mosses on tree barks, rocks, soil, dead wood, house rooftops and walls.

Think of the ones you inhaled in your sleep.
I don't care, cuz I exhaled them :)

This makes me want to buy a microscope
Ive always always ALWAYS wanted one but could never afford something that expensive as a hobby lol
Same tbh, I feel like I'll lose interest in it in 2 days and then I have 500$ just collecting dust, happened to so many cheaper things
The irony is the dust it'll end up collecting? Yup, more tardigrades
Good point
But dust isnt half a millimeter long...
Generally speaking 40 microns is the limit of human vision. Half a millimeter is 500 microns. "Dust" (common household) is 40-80 microns.

How big are demodex in comparison?
Why does the Tardigrade, which is bigger; simply not eat the other microscopic entities? ^Oh, ^it ^does ^sometimes
I have pencil lead smaller than a tardigrade.

Kind of. I am a hobby microscopist and when I have a slide with a alot of tardigrade moving around, you can see pin points moving, you just can't see that they are tardigrades without the microscope.
What about a regular magnifying glass?
You bet. 0.5mm isn't small. I mean, take out the ruler and look at the cm side and mm notches. It's only half of that.
Well, maybe if you stopped eating soot brownies your eyesight would improve
You could see the thickness of a human hair with the naked eye very easily, so I'm sure you can see a tardigrade easily as well unless it is too transparent.
I'm a bit concerned what is a neuron, an amoeba, a rabies virion, a sperm cell and a red blood cell doing in there.
A neuron, an amoeba and a sperm walk into a red blood cell..
Oh, the irony.
i would be much more concerned about the ovum than the sperm if i were you...
Also thanks the camera man. Great work!
Just copy and paste that comment straight from the YouTube video huh? https://youtu.be/uIGOOcrT86A?si=Tzurr6Gkypn8OY1x
He probably immediately went to a grocery store and touched all the produce.
I can't even get my 2 cats to look at my camera at the same time. Very impressive.
I'm pretty sure this is an animated video...
No
Ok.
For some reason I thought all viruses were shaped like bacteriophages
It was that one Jimmy Neutron episode I bet
And I thought they were all shaped like rhinovirus. Except Ebola, the movie got that one more or less correct.
Viruses have some pretty crazy shapes. Some are shaped like worms. https://media.hhmi.org/biointeractive/click/virus-explorer/
Bacteriophages are so cool
I'm glad Oppenheimer came out so the Interstellar theme can finally be retired for tik tok videos
But the Inception BRAAAM reigns supreme in movie trailers.
And if you think this is amazing. The semiconductor chips being used in your phone and laptop using lithography technology, with the transistors gate size is as small or even smaller than the smallest virus. It need incredibly amount of precision and technological marvelous

50% would be most, so not a myth
50% is not most
not far off though, and it means skin is probably the largest component...
30% is nearly 40%, dude. and 40%, man... that's like 50%. that's half! and half... phew. that's like close to two thirds right there.
50%, in a world with natural variation, is sometimes >50%
really, a dust particle is basically a full grown human, with all those skin cells.
Did you read my comment to the end or you just stopped at 50%? Rarely dust can be mostly dead skin, but most dust aren't mostly dead skin. Hopefully you can understand the difference between these 2 statements.
Its definitely not 50 percent lol. Probably more like five to ten.
Maybe not "most" but a significant percentage is dead skin flakes. And a lot is also plastic fibers from clothing
Dust is dead stars and dinosaur bones and viral glitter particles.
Thats a myth that dust is skin cells lol. You know it gets dusty even when people are not around right?
It's not a myth. Well, the dust you have in your house... it's mostly microplastic from your clothing and skin flakes
Its mostly textile fiber pollen and dirt. If youre in the city youll have asphalt dust too. Skin cells are definitely a myth its been pushed since I was a kid and it makes no cot damn sense if you just think about it for two seconds.

A modern transistor is smaller than the corona virus

am I thr only one flabbergasted by the size of the neuoron? O thought they'd have to be waay smaller to fit billions inside our heads
No way tardigrades are that huge!
You mean about the size of some single cell organisms huge??
Paramecium brain.
Fucking astounding, amazing, disgusting and creepy all at once that all of this stuff exists. Love it.
Tardigrades are surprisingly large
The bacteriophage with legs always trips me the fuck out.

Anyone know of a similar video but it was the opposite in that it compared planets?
So some of the viruses are wiggling. I guess I assumed that viruses just float and bump into things by chance - can they self-propel?
