Very interesting indeed. I wonder how they made it self-regenerate. I think I've seen something like this before. It was in a presentation on nanoscience presented to us in the school. There are polymers that retain their shape after they've been contorted, twisted, or damaged. However, I've never heard of any polymers REGNERATING. Hmmm.... regenerating? Sounds like we're one step away from inventing the Borg. Self-regenerating compounds could lead to implants, could lead to nanoprobes, could lead to the end of the world! Well, maybe, but more likely service drones . Anywho, that's my input about this.
