Al Jazeera reports: Scientists 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”.

The Details

Yet living organisms almost exclusively use only one version, a phenomenon known as “homochirality” – from the Greek word for hand – that has puzzled chemists for more than a century. Soai, speaking by phone to the Nobel Prize news conference, said he had been out shopping when he received the news.
