Scientists Henri Kagan and Kenso Soai won the 2026 Nobel Prize in Chemistry "for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis," the award-giving body said on Wednesday. The chemistry Nobel, always the third prize to be awarded during Nobel week, followed those for medicine and physics announced on Monday and Tuesday. "So this year's prize is about foundational chemistry. Many molecules occur in two different versions. Like my hands. They are one another's mirror image, they look alike, but they are not identical. I cannot put my hands on top of one another. Such molecules are called chiral, from the Greek word for hand, Heiner Linke, Chair of the Nobel Committee for Chemistry, said. Established in the will of Swedish inventor and businessman Alfred Nobel, the prizes for achievements in science, literature and peace have been awarded since 1901, with a few interruptions mostly due to the world wars.
