2017 Ig Nobel Prize honors cats' fluid dynamics, study on why old men have big ears, and more

The Ig Nobel Prizes honor “research that makes people laugh and then think.” Marc Abrahams, editor of the Annals of Improbable Research, founded this prize in 1991, which honors the most unusual and imaginative achievements. According to the Ig Nobel website, the main goal of the prize is to spur people’s curiosity and to raise the question: “How do you decide what's important and what's not, and what's real and what's not—in science and everywhere else?” This year ten prizes were handed out for research in various fields. Below is the list of the research projects that were honored in a ceremony in Boston:  

1. Are cats both solid and liquid?

The Physics Prize was handed to Marc-Antoine Fardin, “for using fluid dynamics to probe the question "Can a Cat Be Both a Solid and a Liquid?"

2. Playing didgeridoo to help with snoring and sleep apnea

The Peace Prize was awarded to Milo Puhan, Alex Suarez, Christian Lo Cascio, Alfred Zahn, Markus Heitz, and Otto Braendli, “for demonstrating that regular playing of a didgeridoo is an effective treatment for obstructive sleep apnea and snoring.”

3. How contact with a crocodile can affect willingness to gamble

The Economics Prize was given to Matthew Rockloff and Nancy Greer, “for their experiments to see how contact with a live crocodile affects a person's willingness to gamble.”

4. Is there a reason old men have big ears?

The Anatomy Prize went to James Heathcote, “for his medical research study "Why Do Old Men Have Big Ears?"”

6. What happens when you walk backwards with a cup of coffee?

The Fluid Dynamics Prize was awarded to Jiwon Han, “for studying the dynamics of liquid-sloshing, to learn what happens when a person walks backwards while carrying a cup of coffee.”

7. When vampire bats include human blood in their diet

The Nutrition Prize was given to Fernanda Ito, Enrico Bernard, and Rodrigo Torres, “for the first scientific report of human blood in the diet of the hairy-legged vampire bat.”

8. A study on people disgusted by cheese

The Medicine Prize went to Jean-Pierre Royet, David Meunier, Nicolas Torquet, Anne-Marie Mouly and Tao Jiang “for using advanced brain-scanning technology to measure the extent to which some people are disgusted by cheese.”

10. The best way to play music to human fetus

The Obstetrics Prize went to Marisa López-Teijón, Álex García-Faura, Alberto Prats-Galino, and Luis Pallarés Aniorte, “for showing that a developing human fetus responds more strongly to music that is played electromechanically inside the mother's vagina than to music that is played electromechanically on the mother's belly.”
