By isolating these specific odors, scientists have give us the ability to better articulate the specific ways in which other people are disgusting to us (“Frank smells like rotting fruit because of his butryic acid problem”), but no clear way to solve the problem. The issue remains that odors are intensely complicated. The arise from the compounds, sure but also from the way compounds and bacteria react to heat and sweat and the presence of substances secreted by human glands. Body odor is a cocktail and the ability to name some of the ingredients does not a recipe, make less a chaser, make.

The bees from the genus Euglossa formulate their unique perfumes for reasons similar to ours: to attract mates, establish a signature identity, and smell good in a crowd. They do this by gathering a variety of carefully selected scents from their environment, and then douse their bodies with the perfume.
“The males expose them at the places where mating occurs,” said co-author Thomas Eltz of Ruhr-University Bochum, “so the perfumes may be chemical signals to females.”
