At KAIST in South Korea, a research team has developed a computational framework called NUDGE that guides cells toward desired biological states through a single, temporary intervention rather than permanent genetic modification. The work addresses one of regenerative medicine's deepest tensions: how to direct a cell's fate without stripping away the adaptive flexibility that makes life resilient. By mapping the logical grammar of gene regulation and identifying the minimal nudge required, the system allows the cell's own machinery to complete the journey — then lets it remain free. It is, in
