The 2026 Nobel Prize in Physiology or Medicine to Peter Hegemann, Georg Nagel and Karl Deisseroth
The Nobel Prize in Physiology or Medicine 2026 is awarded for optogenetics — a method that makes it possible to show how nerve cells shape memories, feelings and behaviours in the living brain. Peter Hegemann and Georg Nagel discovered a remarkable protein, channelrhodopsin, in a single-celled alga. Karl Deisseroth transformed the protein into a light-controlled switch for nerve cells. The laureates have laid the foundation of a new era in neuroscience.

In addition, we give our new adjunct and visiting professors a warm welcome, and honour recipients of several academic awards.
