Seven cuttlefish with an added gene reportedly glow red under fluorescent light

News from Science reports that Columbia neuroscientist Tessa Montague spent six years and worked with thousands of embryos to produce seven cuttlefish carrying a synthetic fluorescent-protein gene in every cell. They glow red under fluorescent light, and their offspring glow too. The outlet describes the work, posted as a preprint, as the first successful addition of a new gene to a cephalopod. Montague wants to study how cuttlefish brains control camouflage.
