50 Terabyte DVD

Professor V Renugopalakrishnan (yeah I didnt bother either), of the Harvard Medical School in Boston, claims to have developed a system that will allow the capacity of DVD’s to increase to an exponential 50 Terabytes using a thin layer of a protein named Bacteriorhodopsin (bR).

From the Yahoo article, “The light-activated protein is found in the membrane of a salt marsh microbe Halobacterium salinarum and is also known as bacteriorhodopsin (bR). It captures and stores sunlight to convert it to chemical energy. When light shines on bR, it is converted to a series of intermediate molecules each with a unique shape and colour before returning to its ‘ground state’.”
