    Man with many piercings denied entry to Dubai

    A heavily tattooed German man whose face is embellished with horn implants and more than 100 piercings said Sunday he was refused entry to Dubai without reason, forcing him to skip a planned appearance at a nightclub.  His look may have been a step too far for the Gulf's most liberal city, where a carefully cultivated reputation for tolerance and cutting-edge cosmopolitanism occasionally clashes with the region's conservative Islamic values.

It turns out clues about a person’s identity and ethnicity can come from a surprising source: earwax.

Researchers from the Monell Chemical Senses Center in Philadelphia decided to analyze earwax as a possible source of personal information based on previous studies in which researchers analyzed underarm odor to unlock clues about a person’s identity.

"Our previous research has shown that underarm odors can convey a great deal of information about an individual, including personal identity, gender, sexual orientation and health status," study author George Preti, an organic chemist at Monell, said in a press release. "We think it possible that earwax may contain similar information."

For their study, Preti and his colleagues identified odor-producing compounds contained in earwax obtained from 16 healthy men. Eight of the men were Caucasian while the remainder of the men were of East Asian descent.

Researchers then heated the earwax samples to prompt them to produce odorous volatile organic compounds (VOCs). Though all of the men’s earwax samples tested positive for VOCs, Caucasian men had greater amounts of 11 out of the 12 VOCs tested compared to the men of East Asian origin.

"In essence, we could obtain information about a person's ethnicity simply by looking in his ears,” study author Katharine Prokop-Prigge, a Monell chemist, said. “While the types of odorants were similar, the amounts were very different.”

Furthermore, they suspect earwax may be a source of even more clues about a person’s identity and habits.

The researchers suspect that the fatty nature of earwax makes it a likely repository for lipid-soluble odorants produced by certain diseases and the environment.

Monell chemist Katharine Prokop-Prigge points out that at least two odor-producing metabolic diseases (maple syrup urine disease and alkaptonuria) can be identified in earwax before they can be diagnosed using traditional techniques such as blood and urine analysis.

“Odors in earwax may be able to tell us what a person has eaten and where they have been,” said Preti. “Earwax is a neglected body secretion whose potential as an information source has yet to be explored.”

Future studies will examine these possibilities.

  • Why we yawn

    Why we yawn

    Tuesday, August 19 2014 10:53 PM EDT2014-08-20 02:53:59 GMT
    We all yawn, but why we do it has long been a mysterious phenomenon. Turns out scientists have disproved the old "getting oxygen to our brain" theory. While we often yawn when we're sleepy, it may not be the sleepiness that's causing the yawn. "It's not surprising that there's a heightened level of yawning associated with being sleepy," says Dr. Andrew Gallup, an assistant professor of psychology at SUNY Oneonta and a leading researcher on the subject of yawning.
