how do we know this isn’t just a closeup of a tardigrade butthole?

They’re well studied.

I clicked because of that hole but came here because of the tardigrade upskirt pics.

Hard to believe. To prepare a sample for an electron microscope you need to freeze it to nitrogen temperatures or below. You can fix it using glutaraldehyde, but again, you need to cut it accurately immediately after the penetration. My bet is that either stabbed dead skin or some sort of graphics.
MBech@feddit.dk 2 months ago
Also seems wildly overkill to use an electron microscope for this.
vivalapivo@lemmy.today 2 months ago
That’s an elephant in the room here
flora_explora@beehaw.org 2 months ago
Yes! When I did electron microscopy, we had to cover the fix the samples and cover them with a very thin gold layer beforehand.
vivalapivo@lemmy.today 2 months ago
Yeah, and it’s impossible to catch color!

In rationalist hell there is a special teapot for people who color SEM images
Phineaz@feddit.org 2 months ago
Thanks, I hate it. Not because of the hole, but because of how unhealthy the skin looks in this picture.
cRazi_man@europe.pub 2 months ago
Were you expecting it to be smooth like plastic? The top layer is basically a bunch of dead skin cells that keep flaking away from the top layer and building up again from the lower layers.

Not if you moisturize

I am aware, but it still looks very unsettling. The fake colour actually makes it worse I think, because I have seen plenty similar pictures in gray scale
angrystego@lemmy.world 2 months ago
It would only be smooth if it was shark skin.

Scanning electron microscopes image in a vacuum. Nothing looks 100% like it does at sea level when you suck all the air out.

Most SEMs use a vacuum chamber to get their photos. Also, it’s also not uncommon to sputter a conductive coating onto the surface you’re scanning.
How the hell did they get this photo?
Pulptastic@midwest.social 2 months ago
Environmental SEMs do not require vacuum and can be used for nonconductive samples. The beam ionizes the air which prevents the sample from charging. Magnification is limited but it is more than enough for this.
You can tell it is SEM and not optical by the depth of field. An optical image at this magnification would have much less DoF so the peaks/valleys would be blurry.
JayDee@lemmy.sdf.org 2 months ago
That’s very cool. I had not heard of ESEMs till you commented. I’ll have to look into them more.
ikidd@lemmy.world 2 months ago
Put a needle in someone, freeze them solid with liquid nitrogen, then take a picture. Throw body out with rest of specimens.
Easy peasy.
Duckingold@lemmy.world 2 months ago
It likely wasn’t done on an electron microscope, or at least there is no reason to. There is no scale bar, but quick look online tells me a very fine needle is about 0.016in. 500x magnification optical lens would give you more than enough resolution for a photo like that.
princessnorah@lemmy.blahaj.zone 2 months ago
I’m more intrigued by the fact there’s no blood, they must’ve taken this milliseconds after the needle was removed? Or it’s a dead body.
jaybone@lemmy.zip 2 months ago
They could have remained a portion of the skin. But as another commenter notes, this is too large to need an electron microscope.

Just about everything can seem big when you have an electron microscope

Wonder what it looks like after I scratch it for 50 minutes straight because my pain receptors are bad and I won’t stop till I see blood.
fox@hexbear.net 2 months ago
It’s from a series Anne Weston at the Francis Crick Institute did. Scanning electron microscopy. The full series is pretty cool.

Also why you don’t re-use needles:
