Squid protein makes textiles self-healing
You might be able to repair your ripped jeans one day just be adding water, thanks to a breakthrough from Penn State researchers.

If the material is torn, you just need to put the edges together, apply warm water and it magically "heals," as flexible and strong as before -- even after being laundered.
