For as long as medicine has confronted paralysis and blindness, the central nervous system's refusal to repair itself has stood as one of biology's most stubborn walls. Now, a team of researchers working across fruit flies and mice has charted a molecular brake system—built from three proteins called Rtca, Rab10, and integrin β1—that actively suppresses nerve regrowth after injury. By disabling components of this pathway, scientists coaxed severed axons in mice to regenerate beyond spinal cord and optic nerve injury sites, suggesting that what has long looked like biological fate may, in fact,
