writes to tell us that a Harvard Professor is claiming to have developed a new variant of a protein called bacteriorhodopsin (bR) that, when layered on a DVD, can store up to 50TB of data
. From the 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 color before returning to its 'ground state.'"
