@scientificamerican: Karl Deisseroth won the Nobel Prize TODAY. Here's his reaction. #nobel #Science #breakingnews The 2026 Nobel Prize in Physiology or Medicine is awarded to Deisseroth, along with Georg Nagel and Peter Hegemann, for their discovery of channelrhodopsin and optogenetics, the ability to control cells using light and genetics. Optogenetics allows scientists to use light to switch cells on and off. Using light-sensing proteins called rhodopsins, optogenetics enables precise targeting of cells, such as brain cells, to understand what they do. 📝: Jackie Flynn Mogensen 🎞️: @jeffdelscience
