The purpose of the research was to see if humans sent chemical messages to each other, just like animals do.  Scientific studies showed that women who spent time together had menstrual synchronization.  Further study showed that people could actually sense each other's feelings by the smell of their sweat.  In an experiment people's sweat was collected from their armpits while they were watching a scary film.  Another group of people was given the gauze pads with the scent of the sweat.  They were able to tell that the person that sweated was is a scary stressful situation.  This experiment proposed that humans can detect fear or stress of others through smell.  The researchers are trying to identify the compounds of our chemical messages.  They estimated that body odor is derived from about 120 compounds.  The chemical compounds were not identified yet, but with further research we will soon find out the compounds and solve the mystery of the human chemical message.
