Chemists Build Squishy Rubiks Cube From Self-Healing Hydrogel

A team of chemists from the U.S. and China have constructed a cube of colored, self-healing hydrogel blocks, which looks and acts like a Rubik’s Cube®. Not only is it fun to play with, the researchers say their work might inspire new ways to store information or be used in a range of medical applications. Lead researchers are Jonathan Sessler, professor of chemistry at The University of Texas at Austin, Xiofan Ji, a former postdoctoral researcher at UT Austin, and Ben Zhong Tang, a chemist at Hong Kong Uni
