Researchers say they have been able to store the digital data of thumbnail-sized images on molecules smaller than DNA and retrieve it with ~99% accuracy  —  DNA isn't the only molecule we could use for digital storage.  It turns out that solutions containing sugars, amino acids and other small molecules could replace hard drives too.
