Exciting or Funny?

Does a thriller smell different than a comedy? Of course not; after all, olfactory cinema has not yet been invented and emotions are created by images and sounds. However, it is now known that plants and insects pass on information via chemical substances. So, why wouldn’t humans do the same as well? Scientists from the Max Planck Institute for Chemistry and the Johannes Gutenberg University of Mainz have investigated this question. For this purpose, they have chosen a place where many people feel the same feelings simultaneously: the cinema.
