Researchers catch a whiff of "aroma fingerprints"

While we've already seen just how savvy dogs are at scouting out cellphones, researchers around the globe have teamed up to find out how pups distinguish the aromas that each individual emits, and the result is a highly influential electronic nose. Now if the boys in blue can't track you down via fingerprint, EEG signatures, or just looking at those guilt-filled eyes, it looks like your "aroma fingerprint" just might find you out anyway. The team has uncovered that each human has at least 44 chemical compounds in their odors that can be distinguished, and aside from assisting in identification, can be used in forensic studies to determine true causes behind crimes, deaths, or other misdemeanors. It's even stated that this new technique can assist officials in learning about one's "gender, lifestyle, whether or not they smoke, recent meals, and stress levels." Of course, criminals could be shaking in their boots, but until the scientists find a way to sniff through "deodorant and perfume," we can't exactly count on this being reliable.
