The 2026 science Nobels: algae, Antarctic ice and mirror-image molecules
The prizes honored work on optogenetics, the IceCube neutrino observatory and molecular “handedness.”
Updated
Medicine (announced Oct. 5): Karl Deisseroth, Peter Hegemann and Georg Nagel won for discoveries concerning light-gated ion channels and optogenetics. Hegemann and Nagel found channelrhodopsin, a light-sensitive protein, in a single-celled alga; Deisseroth turned it into a switch that controls nerve cells with light, first in rat neurons in 2005 and two years later in the brains of living mice.
Physics (Oct. 6): Francis Halzen of the University of Wisconsin–Madison won for decisive contributions to the IceCube Neutrino Observatory, a cubic kilometer of South Pole ice fitted with light sensors and finished in 2011, and for the discovery of high-energy neutrinos from far outside our solar system. Halzen first pitched the idea in 1988.
Chemistry (Oct. 7): Henri B. Kagan and Kenso Soai won for discoveries showing how reactions can end up producing just one of a molecule’s two mirror-image forms. That matters because living things use only one mirror-image form of amino acids, and in medicines usually only one mirror image has the desired effect.
The economics prize (Oct. 12) went to Robert E. Hall and Michael Woodford for the microeconomic foundations of models that central banks around the world use to smooth out booms and busts.
Each science prize began with a curiosity-driven question. How does an alga swim toward light? Could ice catch particles from deep space? Why does nature pick one mirror image? The payoffs came later.
