A structural model of green fluorescent protein, a workhorse of biotechnology.Credit: Laguna Design/Science Photo Library An artificial intelligence (AI) model that speaks the language of proteins — one of the largest yet developed for biology — has been used to create new fluorescent molecules.The proof-of-principle demonstration was announced this month by EvolutionaryScale in New York City, alongside US$142 million in new funding to apply its model to drug development, sustainability and othe...
