Google has used an artificial intelligence to produce a map that relates smells to the structures of molecules. It is as reliable as a human in describing the odour of a substance and the researchers behind the work say it is a crucial step towards digitising odours.

The hope is that the AI model could eventually be used to identify new scents for fragrances and flavours for food science, or come …
