The Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Chemistry equally to French chemist Henri B. Kagan and Japanese chemist Kensō Soai for discovering nonlinear effects and autocatalysis in asymmetric organic synthesis. Many molecules exist as mirror-image forms like left and right hands, yet biology and medicine often require only one. Kagan established principles for producing one configuration with high selectivity, while Soai discovered that some chiral molecules can catalyze their own formation and amplify a tiny initial imbalance. The work advanced chiral drugs and fine chemicals and helps explain life's preference for one handedness. It is a foundational mechanism, not proof that every medicine is directly made through these reactions.
Controlling which side a molecule takes turns a mixture into chemistry that can be designed with precision.
Doudoulong, in plain words
A foundational mechanism changes the toolbox, but it is not the single source of every modern medicine.
