The gel can flow freely as a liquid until poure back into water, where it reforms its original shapeIt might look like a pink gloopy liquid to begin with but when you pour Dan Lou's DNA hydrogel into water it spontaneously reforms into its original shape. Even the Cornell researchers aren't exactly sure why their new material does what it does, but the potential applications are causing excitement.The hydrogels are made from incredibly long strands of DNA that tangle up, trapping water in its structure. The researchers think that once the hydrogels are taken out of water they collapse under...
