Kenso Soai and Henri B. Kagan won the Nobel Prize in Chemistry 2026 after the Royal Swedish Academy of Sciences awarded them for a solution to a chemical mystery that has lasted for over 100 years. Soai learned the news while out indulging in recreational consumerism, not while waiting by a phone for the call.
Homochirality and life
The award centers on homochirality, the fact that life favors one handedness of molecules over another. Molecules used by life, including amino acids, are chiral, which means they exist as two enantiomers that are mirror images of one another. Life is highly selective and uses only one enantiomer for sugars or amino acids.
Patrick Walter on the call
Patrick Walter wrote, “It seems Kenso Soai was indulging in a spot of recreational consumerism when he got the call from the Swedish Academy of Sciences.” He added, “He clearly wasn’t sitting by his phone hoping for that call!”
The live update from 2026-10-07 placed the announcement at the center of the Nobel Prize in Chemistry 2026 coverage. That report also noted four chemistry laureates who died in 2026: Rudy Marcus, Louis Brus, Ada Yonath and Hideki Shirakawa.
Royal Swedish Academy of Sciences
The Royal Swedish Academy of Sciences made the award decision on 2026-10-07. The result puts Kenso Soai and Henri B. Kagan in the Nobel Prize record for work tied to a longstanding question about why life uses one molecular handedness, and the source does not set out any further procedural step after the announcement.
