Now, scientists have made a second important discovery about my favorite gene. It also leads to earwax that smells different. Ugh, I know, right? But yes, a team of researchers from Pennsylvania gathered samples of earwax, baked them to get them to release their volatile compounds, then analyzed those compounds with gas chromatrography and mass spectrometry. The earwax came from eight men of Asian descent with dry wax, and eight men of European descent with wet wax.
