A squishy Rubik`s Cube that chemists built from polymers holds promise for data storage
(PHYSorg.com Chemistry)

A team of chemists from the U.S. and China have constructed a cube of colored, hydrogel blocks, which looks and acts much like a Rubik`s Cube. The researchers say their work is more than just fun to play with: it might inspire new ways to store and detect information, and possibly even help patients monitor their medical conditions.
