Very stupid (M.Wei *** erger/Live Science)

Science, it turns out, sounds stupid. That’s where the Ig Nobel Prizes come in: These awards honor research that first makes you laugh, and then makes you think. Here are the serious and interesting scientific studies that were honored at the 27th First Annual Ig Nobel Prize Ceremony at Harvard University's Sanders Theater. Why are crocodiles dangerous to gamblers (Chameleon Eyes/Blinds)

What do crocodiles and poker have in common? Well, not much, except that someone who holds a bit of alligator might be willing to pay a higher bet. Of course, there are some nuances. For the study, detailed in 2010 in the Journal of Gambling Research, researchers surveyed 62 men and 41 women, some of whom held a saltwater crocodile in Queensland before playing a video game console. Those who were risky gamblers and those with few "negative emotions" bet on average higher after holding the Alligator than those who did not. The reptilian study, titled "Never Smile at a Crocodile...," won a Nobel Prize in Economics. Didgeridoo (Erich Haubrich/Shutterstock)

The benefits of having a snoring partner? A bit of didgeridoo play might be in order. Really. A team of scientists wanted to see if playing the organ, invented by Australia's Aboriginal people, could be used to treat a form of obstructive sleep apnea - a condition in which a person repeatedly stops breathing during sleep , and then began breathing health disorders. One of the symptoms is loud snoring. Their study showed success, at least for those with moderate disease. Their music research was published online in the British Medical Journal in 2005 and won the Peace Prize. This year's "Rheology of Cats"

The physics prize was awarded to Marc Antoine Fardin of the Laboratory of Statistical Physics in Lyon, France. The award-winning study, titled "Can cats be both a solid and a liquid," is published in the journal Rheology Bulletin, "The Rheology of Cats." In this study, Fardeen explored how cats "flow" like liquids—think fluffy jumping into an oddly shaped container (that, of course, looks too small), only to True to its shape, the properties of a liquid. Fardeen said he got the idea from 15 pieces of evidence he read online about cats being liquid. He uses the alleged number of Deborah to get to the bottom of the matter. This figure is based on the idea that, given enough time, everything flows...even cats! "Why do old people have big ears" (Featureflash Photo Agency/Shutterstock)

The Anatomy Prize was awarded to James Heathcote for his research on ears. The research was published in the 1995 issue of the British Medical Journal (British Medical Journal), focusing on answering the question: Why do older people have big ears? Well...are they more likely to listen to you? Heathcote and three other GPs started measuring ears; they always*** The left ears of 206 patients, ranging in age from 30 to 93 years old, were actually found to have larger ears as they aged, showing that the ears grew 22 millimeters a year. The paper did not answer why this happened, just that. Says a person's ears continue to bloom even when the rest of the body appears to have stopped growing. Cave insect reproductive organs reverse (Current Biology, Yoshizawa et al.)

Cave insect reproductive organs gain biology. Award. The research team found the first cases of reproductive organ reversal in four species of the Brazilian cave insect genus Neotrogra, where males have vaginal discharge and females have vaginal discharge. They found that these females have what's known as a vaginal discharge. In contrast, males have gynoecium (pictured), a penis-like genitalia made up of muscles, ducts, membranes and spines. Researchers have suggested possible reasons for the reversal, including the structure. Allowing females to mate more frequently for a long period of time.

Their study was published in the journal Current Biology in 2014. How to Spill a Cup of Coffee (Bashutskyy/Shutterstock)

Any regular coffee drinker knows that spilling a cup of coffee is easy, especially on the way to work. What if you had to drink your morning coffee backwards? Enter Jiwon Han, a student at the University of Virginia. He won the fluid dynamics prize "for his studies of the dynamics of sloshing liquids and understanding what happens when a person walks backwards carrying a cup of coffee," according to a statement. Han Han was still a high school student when he completed this research in 2016 and published it in the journal Life Science Achievements. Vampire bat transformed into human blood (Gerry Carter)

Nutrition Award Winner Blood Straw. Three researchers first reported human blood in the diet of long-legged vampire bats (Diphylla ecaudata) in 2016 in the Journal of Pterodactylus. By analyzing the vampire bat's prey in the dry forests of Caatinga in northeastern Brazil, researchers found chicken and human blood in the mix. Their findings suggest that the bats consumed this novel "prey" (human blood) because there weren't enough of the usual suspects around: wild birds in the forest. Brains on Cheese (African Studios/Shutterstock)

Some people can't survive without cheese, while others, well, it turns them off. Now that "ew" feeling has a scientific backing. A team of scientists used brain scans to measure some people's aversion to cheese. Their study, published in the journal Frontiers in Human Neuroscience in 2016, showed that people who disliked eating cheese had more reward areas in the brain called the globus pallidus and the substantia nigra, which are part of the basal ganglia, than those who liked cheese. More active. To activate the brain, researchers used cheese smells and pictures. Is it me or my twin (Nikita Vishneveckiy/Shutterstock)

Really? ! Is it really hard to tell identical twins apart? According to a 2015 study published in Public Science Library General, the answer is. In the study, researchers asked a pair of identical male and female twins to look at a series of photos of themselves, their twin, and a friend's face (minus any hair, etc.); both upright and inverted. Most people are better at recognizing their own faces than others, but this is not the case with identical twins, who are just as good at recognizing their own faces as their twins. How fetuses like their own tunes (digitalskillet/Shutterstock)

The Ig Nobel Prize in Obstetrics is awarded to researchers for their findings showing "how the developing fetus responds to music played electromechanically in the mother's vagina" More intensely than the music played by the electromechanical device in the mother’s belly.”
