Curious about why geologists lick rocks or how many nose hairs there are on a human cadaver? Perhaps you’d like a snazzy dead wolf spider to use as a biodegradable robotic gripper? How about a “smart toilet” that analyzes your urine stream and fecal deposits while taking a picture of your anus for good measure? These and other unusual research endeavors were honored tonight in a virtual ceremony to announce the 2022 recipients of the annual Ig Nobel Prizes. Yes, it’s that time of year again, when the serious and the silly converge—for science.

Established in 1991, the Ig Nobels are a good-natured parody of the Nobel Prizes; they honor “achievements that first make people laugh and then make them think.” The unapologetically campy awards ceremony features miniature operas, scientific demos, and the 24/7 lectures whereby experts must explain their work twice: once in 24 seconds and the second in just seven words. Acceptance speeches are limited to 60 seconds. And as the motto implies, the research being honored might seem ridiculous at first glance, but that doesn’t mean it’s devoid of scientific merit.

Citation: “Christine Pham, Bobak Hedayati, Kiana Hashemi, Ella Csuka, Tiana Mamaghani, Margit Juhasz, Jamie Wikenheiser, and Natasha Mesinkovska, for using cadavers to explore whether there is an equal number of hairs in each of a person’s two nostrils.”

This study was triggered by an interest in alopecia areata, a condition marked by hair loss on one’s scalp, eyelashes, eyebrows, and nostrils. Pham et al. noted that many people who suffer from this condition are more prone to upper respiratory infections, allergies, and dryness because the condition also depletes the nose hair lining each nostril. And they realized that nobody had actually gotten around to counting the average number of nose hairs in humans, a first step in assessing what effects the lack thereof could have on patients’ quality of life.

So that’s what they did, using 20 cadavers (10 male and 10 female) from the medical school at the University of California, Irvine. Not only were the hairs counted in each nostril, but they used a measuring tape to determine the distance of hair growth at the upper, lateral, and lower nostril. The results: The average nose hair count per nostril is between 120 and 122 hairs, and nose hairs typically grow over a range of 0.81 to 1.035 centimeters. Trot out those statistics next time you’re desperate to make small talk at a cocktail party.
