Medicine Nobel announced Optogenetics pioneers win

Oct 5

Tagesschau reports that Peter Hegemann, Georg Nagel and Karl Deisseroth will receive the 2026 Nobel Prize in Physiology or Medicine for pioneering optogenetics. Veronika Simon reports Hegemann's reaction and explains the light-sensitive algal channels studied by Hegemann and Nagel and Deisseroth's use of them as switches in nerve cells. Nobel Committee member Abdel El Manira describes the research's use in investigating disrupted brain circuits, blindness, depression, addiction and dementia. The package says initial blindness therapies based on the research are being investigated in clinical trials, and that the three laureates share about €1 million. It does not announce an approved treatment or a new trial result.

Tagesthemen announces the 2026 Medicine Nobel for Peter Hegemann, Georg Nagel and Karl Deisseroth for the work underlying optogenetics. Its package explains light-sensitive ion channels, selective activation or inhibition of nerve cells and research applications. Hegemann's direct interview emphasizes circuit understanding and warns that many therapies may remain years or decades away; early blindness applications do not establish cures for other disorders. Tagesschau's earlier award package adds Hegemann's reaction and Abdel El Manira's circuit-research explanation, describing blindness applications as clinical trials and prize money of about €1 million. DD India airs Thomas Perlmann's original award announcement and reports 12 million Swedish crowns. The source amounts remain attributed; no approved therapy, clinical outcome or completed prize presentation is established. AP's original excerpt in show 354 records Thomas Perlmann reading the Nobel Assembly's decision on October 5: the joint award to Karl Deisseroth, Peter Hegemann and Georg Nagel for discoveries concerning light-gated ion channels and optogenetics. This formal result supports the same award occurrence; the edited biographical tail's omitted identifying setup remains ambiguous in its source story. Repubblica's original announcement excerpt in show 365 supplies Perlmann's complete formal decision and all three laureates' introductions. He identifies Deisseroth's recognized work at Stanford, Hegemann's at the Max Planck Institute for Biochemistry in Martinsried and Nagel's at the Max Planck Institute for Biophysics in Frankfurt, together with their current affiliations. This fuller direct excerpt complements the AP edit without silently repairing words or identifying setup absent from AP's own recording.
