I am Rubber, I am Glue...

So they came out with this nifty new kind of rubber that can knit itself back together after being cut, eventually becoming as good as new! Not only can you put it back together just by kinda pushing and squeezing it like clay, but THEN YOU CAN STRETCH IT AGAIN. Full healing takes about 6 hours, but you can get it to hold together almost immediately, and start stretching it again after about an hour.

According to the Scientific American article, the way it works is by utilizing the same sort of weak hydrogen bonds that exist in water -- after the bonds are broken, they still have a latent attraction to one another and can be recombined.

What remains to be seen is how we'll use this. Proposed applications include "rubber duckies" and "healing tires." Surely we can do better than that? As far as I know, we've never really had a material that combined durability with the ability to squish back into its original state, so there ought to be great new things to do with it.

I have to admit, my first thought was "androids..."
