    Chemists from Monell Chemical Senses Center in Philadelphia found that earwax can identify if someone is of Caucasian or East Asian origins.

    Chemists from the Monell Chemical Senses Center in Philadelphia found that your earwax can tell a lot about you—for instance...where you came from.  Their research showed that earwax substances varied between individuals of East Asian origin and Caucasians.  Their previous work found that underarm body odors convey a lot of info about a person, like identity and health issues, and now they think earwax can too.  They analyzed the release of volatile organic compounds from earwax samples taken from males of both East Asian and Caucasian descent.  They found that 12 VOCs were present in all of the men, but that the Caucasians possessed greater amounts of 11 of 12 VOCs than East Asians.  They said, “In essence, we could obtain information about a person’s ethnicity simply by looking in his ears.”
