The pores on my face as seen by the naked eye.

Everything reminds me of her

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.

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

[–] LordWiggle@lemmy.world 4 points 6 days ago

It also happens to be just big enough for Trump his penis.

Uh-huh.uh-huh. Yip yip yip yip yip

Looks like the hole they dragged the Brain Bug out of.

Also why you don't re-use needles:

[–] leds@feddit.dk 1 points 4 days ago (1 children)

So when nurse misses a vein and want to try again you should ask them to uae a new needle?

[–] jordanlund@lemmy.world 1 points 4 days ago

For good procedure, yes.

[–] LodeMike 171 points 1 week ago (2 children)

That's not the main reason why we don't reuse needles.

One of the many

It's a little misleading in that the last photo is zoomed in a lot more than the previous ones. This one has that without the extra zoom in.

[–] bluesheep@sh.itjust.works 2 points 6 days ago

Comparing the pictures it looks like the exact same set of photos except like you said, more zoomed in.

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

[–] Zacryon@feddit.org 107 points 1 week ago (1 children)

There was missing something...

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.

Thanks, I hate it. Not because of the hole, but because of how unhealthy the skin looks in this picture.

I knit, tiny? makes me want to use a bandaid after I inject black yat heroim these days

[–] cRazi_man@europe.pub 51 points 1 week ago (6 children)

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.

[–] sem@lemmy.blahaj.zone 1 points 4 days ago

Mmm, skin flakes.

[–] angrystego@lemmy.world 2 points 6 days ago

It would only be smooth if it was shark skin.
