Halfassed addition, now with almost some content! Most of which is by way of IFLScience, because I'm a lazy shit and these are mostly just whatever new tech related stuff comes across my desk.

First we figure out how to get hearing damage caused by noise to heal (pending more testing before it gets to people. Very useful for people into guns and such), now we've identified what allows body parts to grow back. Perhaps in the near future, you'll have the options of a chrome replacement or just growing a new one in case of losing a bit of you.
