2026 Nobel Prize in Physiology or Medicine Awarded for Optogenetics, Nearing First Drug Approval for Blindness

Karl Deisseroth, Peter Hegemann, and Georg Nagel have been awarded the 2026 Nobel Prize in Physiology or Medicine for their discoveries in light-gated ion channels and optogenetics. This breakthrough has revolutionized brain science by allowing researchers to control nerve cells with light, and a trial in blind patients has already reported partial sight restoration, with the first optogenetic gene therapy under FDA consideration.
