Hmmm... I found this article, and it seems interesting. Seems like we're trying to make Time Lords (It's a Doctor Who reference). I wonder, though: How exactly would humans obtain this trait? Would genes have to be added to make it work, or is that possible?

Honestly, I don't think we should be trying this. It's unnatural for humans to change genetics.

You could argue every scientific advance ever is unnatural. That's a dumb argument.

Well when the article says "regenerate human tissues, such as damaged spinal chords and even lost limbs" they don't mean extreme regeneration like a whole new arm... most likely... Maybe if you sever your flexor tendon in your finger, which happened to my mother, you can grow it back. As for the spinal regrowth, the regeneration might help MS (Multiple Sclerosis), which my mother also has, and fix other things we don't know much about, like Lou Gehrig's disease.

What about soldiers that lose their limbs in combat? (Or anyone else who loses limbs doing whatever)
