"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.

How it could work in a future: they pre-grow limbs in labs for a few months/yearst, then when somebody needs it, they attach one that matches closely. After that, you get the treatment and the limb continues growing until it reaches the size needed.

Isn't that a Michael Bay film?
