"In a study published in Nature Communications, the researchers reveal an elegant molecular mechanism that acts like a GPS coordinate system for regenerating cells.... the puzzle was how the cells in the regenerating limb-stump controlled their levels so precisely to know exactly where they were on the axis from shoulder to hand.”

Woah, fascinating. Of course very far out, but manipulating and regenerating human limbs in a similar way would be serious sci-fi stuff. Just impressive

Not that I would be an expert, but limbs start forming so early on in the womb, that that will probably be a very difficult thing to do. Nevertheless, never say never.

Hmm, I think I’d rather have a cool cyberpunk robot limb then just regrowing my shitty old flesh and blood one

With a built-in ice cream freezer!
