Researchers are curious beings. They leave no stone unturned. Especially the funny ones. More recently, studies have been conducted on volunteers and clueless people.
Tests to determine their neurotic nature, honesty, and appreciation for bad jokes were boundlessly strange. The answers even more. They also threw the cold at cancer, were considered the extinction of chocolate and took Godzilla's growth rate very seriously.
10 Right way to pet a cat
Some cats are confusing. One second, they love to scratch their heads. Next time, they irritably scratch their owners to stop them. A recent study blamed its ancestors.
Cats have been milking milk for 4,000 years after a saucer. As they approached humans, their genes remained similar to those of their ancestor, the African wildcat. As domesticated cats are, one foot remains firmly planted in their wild past. This collides with human nature. People touch their pets to show affection. The African wildcat is lonely and actively avoids its own species.
The cat has to sit in the driver's seat. The study found that kittens allowed their owners to give them more physical affection for a longer time when they began to bind. They also enjoy it when their chin, ears and cheeks are scratching, though not so much back, stomach or tail.
The owner must also pay attention to the body language of his fuzzball to detect negative signs and then back away. In the end, it is important to respect the limits of your cat. 
9 Preserved Laughter Helps Bad Comedy
TV critics do not like riddles of laughter. They see it as a decades-old relic that should have disappeared with the bad actors and everyday stories of the time. However, viewers still hear traces of laughter as an indication of a comedy.
In 2019, a study selected 40 jokes. They were all bad. The researchers wanted to find out whether conserved laughter can improve their fun factor. First, 20 students were tortured with the flat lines, without a giggle was heard before. Predictably, the jokes were rated low. On a scale of 1 to 7, none was rated higher than 3.75.
Finally, 72 adults judged the jokes without laughter, then with obviously false laughter and finally with spontaneous laughter. The ratings were raised by forced humor by about 10 percent. However, the best peak – between 15 and 20 percent – came when the volunteers listened to laughter that gave real joy. 
Children's ratings may have been triggered by human reactions to what is laughing, a primitive signal that is crucial to human attachment. Inherently, it was more about joining the group than enjoying a bad joke.
8 Seducing People with Wallets
In 2015, a group of behavioral scientists decided to test people's honesty. More precisely, the better side of the citizens. The scientists all went out. They traveled the world visiting 40 countries with over 17,000 wallets, lots of cash, credit cards and around 400 keys.
Researchers pretended to be tourists grabbing a wallet. They gave it to employees of banks, museums, police stations and other institutions in 355 cities and asked the staff to find the owner.
Two questions were answered in the study. Do certain countries return more purses and influence the amount of cash they make?
When the result was published in 2019, 300 expert economists came to the fore, predicting that people would steal the purses with more money. However, those in charge of returning the wallets did so more likely to spend large sums of money. The country made no difference when it came to this unexpectedly healthy behavior. 
7 Phone Movements Reveal Personality
A reliable way to determine a person's personality is to measure that person by the Big Five test. The test is originally from the 1980s and is based on five main features. These include openness (curious vs. cautious), extraversion (sociable vs. reserved), conscience (compassionate vs. distant), conscientiousness (organized vs relaxed) and neuroticism (self-confidence vs. nervousness).
As of March 2010, scientists followed 52 volunteers for over a year. The group tried another variation of the Big Five – to see if their personality could be determined by using their phones.
Each phone was equipped with an accelerometer to track physical movement, as well as software that recorded calls and messages. Interestingly enough, the method agreed with certain characteristics of a Big Five survey conducted by the participants.
The data were well-suited to predict extraversion, conscientiousness, and neuroticism. These features increase physical activity, which may explain why the phones did not analyze their openness and tolerability. 
6 Spiders On Drugs
In 1948, spiders got annoyed about H.M. Peters. The zoologist studied spider webs at the University of Tübingen. The ball spiders in his study were early risers. To see her turn, Peters had to wake up between 2 and 5 o'clock in the morning.
He asked the pharmacologist Peter Witt to dose the arachnids with something that would later make them spin. To postpone the belt hours, Witt fed the spiders with sugar water. The sweet drink was mixed with caffeine, amphetamine, mescaline, strychnine or LSD.
The drugged spiders happily changed the patterns and sizes of their nets, but kept to the godless hours of the morning to do so. Peters gave up, but Witt continued his study on spider tips.
In 1995, NASA successfully replicated Witt's work. This time, the spiders produced certain patterns after being soaked in caffeine, marijuana, speed, or chloral hydrate. 
The severity of the deformity of the net depended on how toxic the chemical was. This reaction could change the way that laboratories test poison. The use of spiders instead of complex mammals such as mice is a cheaper and more humane alternative.
5 Extinction of Chocolate
Chocolate addicts reacted with horror as news agencies claimed that their favorite snack could die out by 2050. The reason for this was that cocoa trees, the source of chocolate, continued to face a tough fight against the usual evils.
Several studies have detected fungal diseases in the destruction of cocoa trees in Central America, and it has been suggested that these diseases may spread to other cocoa pills in the world. As a harbinger of epic weather events, climate change can also slow down plantations.
Worryingly, half of the planet's chocolate is produced by two African countries. If Ghana and the Ivory Coast experience climate change, it could make the entire industry vulnerable.
Cocoa trees are sensitive to temperature fluctuations and love to rest in the rainforest. As predicted for 2050, a rise in temperature and drought could mean trouble for chocolate lovers. Scientists are exploring the road of genetically enhanced cocoa trees, but then chocolate would not be as natural as some would like it to be. 
4 Climate apartheid
A scary study from 2019 suggested that climate change could divide humanity. This hypothetical future scenario is called "climate change apartheid". The United Nations Human Rights Council (HRC) has published a report outlining how the dark side of human nature would rise when nature drives to hell affecting every living thing on earth. A frightening thought, considering that the cards predict famine, widespread death and natural disasters. As conditions worsen, people are divided into those who can afford to protect themselves and those who can not afford it.
The HRC report was the concentrated opinion of over 100 studies focused on how climate change threatens the basic needs of human life. These included living, eating, water and health. 
The conclusion warned that millions are sentenced to death without any radical change in environmental policy and immediate plans to safeguard the vulnerable. Ironically, these citizens live in the poorest countries, the least responsible for the pollution that fuels climate change.
3 Godzilla makes fear grow
In 2019, scientists grappled with Godzilla's growth rate. The monster has grown significantly since the first movie in the 1950s, when it was 50 feet high. In the latest version of 2019 it was 120 meters high. This boost is 30 times faster than anything alive on Earth. Had the creature been real, it would have destroyed growth and evolutionary records.
The study looked at ways to explain why the creature seemed to get bigger with each movie. It came to the conclusion that Godzilla was a metaphor for people's existential fear. Politics, environmental issues and personal issues keep stress alive and healthy. 
Godzilla evidently posed great problems that humanity must unite – such as climate change and terrorists. Godzilla, however, could only compete against himself. As moviegoers crave more and more, the classic creature needs to evolve at will.
2 An Unknown Form
Epithelial cells form our skin, line organs and help embryos to develop their innumerable structures. As important as these cells are, scientists can never pinpoint their shape. For lack of a better understanding, it was assumed that they resemble tubular prisms or a truncated cone – a kind of bottle-shaped pyramid.
In 2018, scientists decided to conduct a study to find out which one was involved. They turned to computers to unravel the shape of the epithelial cells. The result was funny. Not only was it not suspicious nor was the form of math and science unknown.
Strangely, it resembled a Y-shaped prism. The top of one branch had five surfaces and the other had six. The new geometric shape was called scutoid. The data suggested that the particular shape helped the epithelial cells flex with curved tissue. 
The discovery has a broader application than merely adding a new form to science. Understanding how Scutoids build tissue could improve the production of artificial organs for transplant patients.
1 The common cold
The idea of attacking cancer cells with a virus is almost a century old. However, the assumption proved correct only in 2019. In one study, 15 patients with early-stage bladder cancer were studied. A catheter was used to infect each person with Coxsackievirus A21. This is one of the viruses that people with common cold beat.
You kept the catheters for one hour before repeating the procedure. This should allow higher virus concentrations to be pumped into the bladder than is normally the case with a natural infection. Then the patients were taken to the surgery to remove their tumors. 
Getting a cold in cancer sounds weak, but the results were stunning. In many patients, coxsackie virus severely damaged the tumors and attracted a legion of immune cells to attack them. Best of all, a patient's tumor has been completely destroyed.
Overall, the onset of cancer could be as simple as using a naturally occurring virus to refine effective treatment. Interestingly, none of the super-infected patients in the study developed a cold.
