Diagnosing some diseases , detecting landmines , detecting food safety, detecting tracks(like dogs), analysis of biocompatiblity of couples(through pheromons),improved robotic chefs can all achieved by smelling. In general , smelling , i.e. analyzing the volatile compounds materials emit can teach us some things about those materials and what processes they are going through.Those seem like usefull capabilities for many industries.
