Henri Kagan, Kenso Soai win chemistry Nobel for ‘mirror image’ breakthrough

Scientists honoured for solving mystery of asymmetric ‘mirror image’ molecules that has helped in manufacture of pharmaceuticals.Published On 7 Oct 20267 Oct 2026Scientists Henri Kagan and Kenso Soai have won the 2026 Nobel Prize in Chemistry for solving a longstanding riddle of asymmetric “mirror image” molecules, a discovery hugely important for pharmaceutical manufacturing.The Royal Swedish Academy of Sciences said on Wednesday the pair – Kagan, 95, from France; and Soai, 76, from Japan – were honoured “for the discovery of nonlinear effects and autocatalysis in asymmetric organic synthesis”.Recommended Stories list of 2 itemslist 1 of 2US support for Israel continues three years into the genocide in Gazalist 2 of 2Justina Shiroka Pula: Kosovo’s new president, elected during a crisisend of listTheir findings showed how chemical reactions can be driven to favour a single molecular mirror image, work that has been key for chemists who design reactions for the manufacture of pharmaceuticals.Many of the molecules essential to life exist in two forms that are mirror images of each other, like left and right hands.
