The area of the olfactory epithelium (red) in dogs is some forty times larger than in humans. Mice – the species Axel and Buck studied – have about one thousand different odorant receptor types.
Humans have a smaller number than mice; some of the genes have been lost during evolution. There are several millions of olfactory receptor cells in our olfactory epithelium.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
