Glow of Jellyfish May Light Way toward New Optical Storage Device

Researchers have found a way of controlling a tailor-made version of a protein that gives the glow to the Pacific Northwest jellyfish. The discovery not only sheds light on the inner workings of the green fluorescent protein (GFP) of the jellyfish Aequorea victoria, it also suggests a potential new way for storing and accessing computer memories in packages the size of a single molecule.
