Axolotls are famous for their extraordinary ability to regrow entire limbs along with tails, spinal cord tissue, and parts of organs including the heart, brain, lungs, liver, and jaw.

Woah, that's a lot of regeneration.

Mice can regenerate the tips of their digits, and humans can sometimes regrow fingertips if the nailbed remains intact after injury, allowing skin, flesh, and bone to regenerate.

TIL.

Unwritten here is how exactly they go about snipping mouse fingers and axolotl tails off. I hope there's at least anesthetic involved.

In mice, the treatment encouraged bone regrowth in damaged digits and partially restored some regenerative abilities lost when the SP genes were absent.

So, sounds like small steps towards identifying part of the puzzle. Cool discovery, but plenty still to do before we're regrowing mouse arms much less human arms.

I always figured them as more of a nipple dick man. You know.. nipples being feminine or whatever he'd get them replaced with two flacid micropenes

I can't remember author or short story name, but this evoked the memory of having read a short story I read some three decades or so ago who had vaginas surgically created all over his wife's body, including several on her face, then invited his friends over to for orgies with her. I don't recall much else about it either, except her sadness and his ultimate disgust with her, even she merely acquiesced; and in some ways, it sort of reminds me of the orisha who cut off her ear to secure the devotion of her beloved, and found herself banished from him.

You never heard that Musk had a botched penis enlargement?

The women he "impregnates" mostly use IVF.

I heard he doesn't even use the one dick he has. Allegedly all his kids are IVF babies.

God I hope that's true and that it bothers him.

In a shock twist the machine is hacked and makes a penis grow out of Bezos’s forehead.

I'm reasonably sure he's just one giant misshapen dick.

[...] humans can sometimes regrow fingertips if the nailbed remains intact after injury, allowing skin, flesh, and bone to regenerate.

The process is established and described e.g. here: https://www.nature.com/articles/s41536-025-00441-y

The original study is over 50 years old and was focussed on children: https://www.docdroid.net/LYIhrKu/1972-child-fingertip-regeneration-pdf
