Scientists actually do crazy studies from time to time and end up relating things to factors you would never have imagined, such as the link between having good oral hygiene and taking less risk of heart attack.
The point is that weirdness and science seem to go hand in hand. Mental Floss has put together a series of completely unusual research. Check out some of the following:
1 - In 2010 a scientist trained pigeons so that animals could identify good and bad children's drawings. Yeah. The fact is that after a while the birds could already choose the best designs based on the quality of the paintings, the strokes and other aesthetic patterns.
2 - In 2001, scientists concluded satisfied research by the Babraham Institute. The study found: sheep can recognize the face of other sheep 80% of the time. What's more, these little animals remember similar ones for a period of two years.
3 - Researchers at Albany Medical College found in 2011 that mice don't enjoy music, but if they are forced to listen to something, they prefer Beethoven to Miles Davis. The opposite is true of cocaine mice, who, after trying the drug and listening to jazz, end up choosing Davis sound even when sober.
4 - In the 1990s the veterinarian Robert Lopez published a study by the American Veterinary Medical Association that was based on an experience in which Lopez was the "guinea pig" herself. In an attempt to prove that humans could catch cat ticks, the vet inserted this type of mite in its own ear. Twice. And yes, it's really possible that feline ticks end up in people.
5 - The Missing Information to Change Your Life: In 2012 a group of scientists found that male athletes have higher levels of saliva testosterone when they squat after watching videos of erotic, funny or violent content.
6 - Does the speed with which the pee exits a man's urinary canal have any relation to the proximity of other guys in the urinal? Maybe it's kind of obvious, but a group of scientists wanted to sort it out in 1976. After observing the behavior of underpants in public toilets, the conclusion: the closer a man was to another man in the urinal, the longer the pee took longer. to get out. In terms of quantity, the proximity of another man also seemed to decrease urine volume.
7 - Look how cool: A 2012 survey found that those who lean to the left have the feeling that the Eiffel Tower is smaller. This is because when people lean, they have their ability to estimate the size of things affected - this is because the human brain tends to interpret objects and people as small when we lean the body to the left. The opposite happens when we lean to the right.
8 - And for this you really did not expect, but chickens like more beautiful people. Yeah. This conclusion was published in 2004 in the Zoology section of Stockholm University.
9 - In 2011, Dr. Anna Wilkinson of the University of Lincoln in the United Kingdom simply trained some tortoises so that these animals would yawn when instructed, so that you could see if yawning is also contagious among these animals. The result? It is not.
10 - In 2003 we were able to learn more about penguin poop. At the time, the journal Polar Biology published the result of a research that evaluated the way the manure was expelled from these cute animals. The fact is, because of really strong intestinal pressure, the penguin poop is thrown out hard and will usually stop 40 cm away.
11 - In the early 1900s, Romanian scientist Nicolae Minovici decided to study hanging in too much an empirical manner. To find out what the hanged people were going through, the guy hung himself 12 times - yes, 12 - with the help of an assistant, who untied him after 25 seconds. Thanks to Minovici's bizarre experiment, many hanging symptoms have been discovered, such as vision problems and ringing in the ear.
12 - A team of researchers at the University of Minnesota decided to show that it was possible to swim in a honey-like substance as easily as anyone swims in water. To prove this, a 25-meter pool was filled with a guar gum fluid - a liquid twice as thick as water. In the end, it is really possible to swim without difficulty.
13 - In 1986, 11 Russian scientists agreed to conduct a crazy experiment, lying 370 days in a bed. The idea was to create a way to help future space expeditions, since after a year lying in a bed these men would be accustomed to a sensation similar to the lack of gravity.
Still regarding bizarre experiences involving sleep issues, in the early 1900s, Dr. Nathaniel Kleitman was studying the consequences of sleep deprivation, analyzing the symptoms in six men who were awake for a few days at a time. The longest sleepless time, however, was faced by himself, who was 115 hours without even taking a nap. The result? Hallucination seizures. In another experiment, Kleitman spent six weeks living on 28-hour days - it was one of the guy's ambitions: to change the length of a day. Little thing.
In the 1970s and 1980s, a group of professors at Florida State University decided to compare the responses of men and women to strangers who suddenly approached and asked, "Would you go to bed with me?" " Most men said yes, and as for women, they all said no.
16 - A group of researchers decided to listen to drunk people in 2013 and found that the more drunk they were, the more they considered themselves attractive.
17 - Much is said about dogs that look like their owners, but is the opposite also true? In 2004, Michael Roy and Nicholas Christenfeld decided to research this and evaluated photos of people and their pet dogs. Guess what? In 64% of cases, the owners were similar to their dogs. What's more, guys have found that it is easier to find similarities between purebred people and dogs.
18 - In the 1980s, psychologist Robert Zions was able to prove that married people begin to resemble each other over time. To reach this conclusion, a group of volunteers received photos to analyze. Of these images, 24 were of newly married couples and 24 were photos of these same couples 25 years later. Next, the volunteers were to group the images of men and women who most closely resembled each other. The volunteers eventually identified much more similarities between married couples longer - it was also easier to guess who was married to whom.
19 - At the University of Quilmes in 2007, research revealed that hamsters recover more easily after time zone changes when under the influence of Viagra.
