US-German trio wins medicine Nobel for illuminating the brain
Summary
The 2026 Nobel Prize in medicine has been awarded to Karl Deisseroth, Peter Hegemann and Georg Nagel for pioneering optogenetics, a technique that uses light to control nerve cells. Their discovery has transformed neuroscience and may eventually help treat conditions such as blindness, Parkinson’s disease and epilepsy.
Key Points
- Karl Deisseroth, Peter Hegemann and Georg Nagel won the Nobel medicine prize for their work on optogenetics.
- Optogenetics uses light to control nerve signals and has helped scientists map brain circuits linked to memory, behavior and disease.
- The method has already seen limited clinical use and could one day support treatments for blindness, Parkinson’s disease and epilepsy.
- German Chancellor Friedrich Merz praised the award as evidence of Germany’s strong research base and the importance of international collaboration.
