The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Chemistry to Henri B. Kagan and Kenso Soai for their research into nonlinear effects and autocatalysis in asymmetric organic synthesis. Their work addresses homochirality, providing methods to selectively drive reactions toward a single mirror-image molecular form, which is vital for the pharmaceutical industry to ensure drug efficacy and avoid toxic side effects.

Kagan, a professor emeritus at Université Paris-Sud in France, made significant strides in the 1980s by discovering how minimal asymmetry in a catalyst can be amplified through nonlinear effects. Kenso Soai, a professor emeritus at the Tokyo University of Science in Japan, advanced this field by describing asymmetric autocatalytic reactions between 1995 and 2003, where the product helps catalyze its own formation to produce a single mirror-image form.

The announcement has sparked celebrations in Japan, including a surge in sales of original mineral water at the Tokyo University of Science. In response, Japan’s Minister of Education, Culture, Sports, Science and Technology, Yoshihiro Seki, pledged to expand fundamental research funding and support policies that foster basic research to strengthen the nation’s research capabilities. The achievement has also prompted discussions regarding Japanese research environments and the academic ties between the University of Tokyo and the Tokyo University of Science.
