Every Person Has Their Own Unique Scent, Duke University Study

Just as everyone has their own individual and unique fingerprint, so does every individual when it comes to body odor. A recent study lead by researchers at Duke University analyzes amino acids that give off certain odors that make each person smell different. Background information from the study notes that there are around 400 genes coding for the receptors in our noses, and according to the 1000 Genomes Project, there are more than 900,000 variations of just those genes. These receptors help us distinguish different ordor through signals fired in the brain when certain scents enter our nostrils.
