A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

That's because the spicy is felt thru thermoreceptors that "feel" if there is any heat, it happened that capsaicin can bond with this receptor, making you feel the spicyness; That receptor is found in both your mouth and your butt, since we don't really digest capsaicin since it's not useful for us, it get in to the shit
Edit: just realized that i wrote this in a science meme sub
I love the fact that you wrote this in a science meme sub. I like getting learning alongside my memes
(I'm a biochemist, so I didn't learn anything in this particular instance, but I frequently find my day brightened by helpful people like yourself, who take the time to explain stuff)
I appreciate the explanations and "did you knows" that appear in science meme subs - so thank you for your answer. :)
Why is there a capsaicin receptor in the butt?
It's a pain perceiver where capsaicin activates it.
Our senses run on chemicals, and that means sometimes chemicals activate these senses. Capsaicin is similar to a different chemical that our bodies use as signal, and binds to the receptor instead.
You could imagine it like a vending machine that's supposed to dispense soda if you put Euro coins in, but it'll equally dispense soda if you put other flat pieces of metal in it.
Wait, so if I put a flat piece of metal in my butt, then I get euros? I love science!
Yes but thru your mouth
Superb explanation!
... bruh...
to keep us from doing stupid things with our butts.
idk why people calling communities "sublemmys" pisses me off, but it does.
But did they? Sub (forum) isn't exclusive to reddit.
