Wow, this is just too cool. A material, made from artificial DNA, that “remembers” its shape after being dehydrated? Sounds like the beginnings of some kind of awesome shape-shifting, amorphous robot to me! Sorta:

Mysterious Material Remembers Its Shape: “The new stuff is a metamaterial, scientists’ word for a lab-made material that has properties uncommon in nature. Even among metamaterials, however, this material is unusual — it’s composed of artificial DNA, while most metamaterials are composed of nonbiological chemicals such as silicon or copper. Its creators are calling it a “meta-hydrogel.”
