The 2026 Nobel Prize in Physiology or Medicine has been awarded to Karl Deisseroth of the United States and Germans Peter Hegemann and Georg Nagel for their discoveries concerning light-gated ion channels and optogenetics, the Nobel Assembly at Sweden's Karolinska Institute announced on Monday. The technique combines optics and genetics to control nerve cell activity with light, and researchers say it has advanced understanding of how the brain works, with potential applications in treating blindness, depression, addiction, dementia and Alzheimer's. The three scientists will share a prize of 12 million Swedish kronor, about $1.2 million. It is the first of this year's Nobel Prizes to be announced, with physics, chemistry, literature, peace and economics prizes following later in the week.

How each side tells it

Compare views

  • the left

    6 outlets

    Left-leaning outlets largely use straightforward descriptive headlines naming the winners and the research field, with some (NPR, New York Post) running an identical AP report while others (Guardian, NYT, Washington Post, Al Jazeera) wrote their own.

    Center outlets similarly emphasize the scientific achievement in neutral, factual headlines, with some outlets publishing multiple versions of the same story as it developed.
