French chemist Henri Kagan and Japanese chemist Kensō Soai were awarded the Nobel Prize in Chemistry. They were recognized for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis. Their work concerned mirror-image variants of molecules, which can have different effects despite having the same composition. Reports said the research is important for, among other things, the development and production of medicines.

The Nobel Prize in Medicine was awarded to German researchers Peter Hegemann and Georg Nagel and American researcher Karl Deisseroth for discoveries in optogenetics. The technique uses light to activate or switch off nerve cells and enables researchers to study brain activity with precision. The work has helped researchers examine how nerve cells are involved in memory, feelings and behaviour.
