Seven cuttlefish glow red under fluorescent light in a reported first addition of a new gene to a cephalopod

NewsfromScience reports that Columbia University neuroscientist Tessa Montague produced seven cuttlefish that glow red under fluorescent light after six years and thousands of embryos. It describes the work, posted as a preprint, as the first successful addition of a new gene to a cephalopod. Montague had hoped to make neurons fluoresce as they fired, to track how cuttlefish brains control camouflage.
