Henri B. Kagan and Kenso Soai were awarded the 2026 Nobel Prize in Chemistry on Wednesday for discoveries involving asymmetric organic synthesis.
The prize recognized them “for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis.” Kagan, 95, was born in France and is affiliated with Université Paris-Sud, Deutsche Welle reported. Soai, 76, was born in Japan and is based at Tokyo University of Science.
Their work addresses chirality, in which molecules can be mirror-image forms of one another. Ars Technica reported that many chemical reactions produce equal amounts of the two forms, while living organisms use only one form in many cases. The discoveries showed that chemical reactions can become biased toward one form.
