The Royal Swedish Academy of Sciences announced the 2026 Nobel Prize in Chemistry will be awarded to Henri B. Kagan of Université Paris-Sud, France, and Kenso Soai of Tokyo University of Science, Japan. They were recognized "for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis." The award addresses the century-old scientific puzzle of homochirality—the phenomenon where life uses only one mirror-image variant of molecules, despite both variants being chemically identical.
The Nobel Committee highlighted that Kagan and Soai provided the solution to how homochirality can emerge spontaneously through specific chemical reactions. Kagan's 1986 discovery enabled greater excess of one mirror image, while Soai's 1995-2003 work developed the first reaction capable of producing only one mirror image, a feat never before achieved outside of living systems. Their research has transformed pharmaceutical manufacturing, where precise control over molecular mirror images is critical for drug efficacy and safety.
The prize amount is 12 million Swedish kronor, to be shared equally. Illustrations related to the discoveries, including 'The Soai reaction' and 'An asymmetric reaction,' are available for non-commercial use. This announcement, dated October 7, 2026, marks a pivotal moment in understanding life's chemical foundations.
