Bacterial DVD Holds 50TB 268
CAMags 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.'"

It was a favourite model of protein scientists in the 80-es because it is one of the very few proteins that will easily form crystals. It is also extremely stable (for a protein) in its non-excited form. So if any photosensitive protein is ever used for storage it is possibly the best candidate.

Scientists should spend more time on figuring out how to leave the world of milliseconds and approach the nanoseconds. Remember, the only thing that's running on milliseconds in a computer is based on platters. I'd rather move on from that and get my 50 TB later.
