Researchers are endlessly curious, and they often chase down the strangest questions imaginable. In fact, 10 unusual studies have surfaced recently that showcase just how quirky scientific inquiry can get, ranging from the perfect way to pet a feline to the astonishing use of a common cold virus against cancer.
10 Unusual Studies Overview
10 Correct Way To Pet A Cat
Felines can be baffling creatures. One moment they adore a gentle scratch behind the ears, and the next they swat at their human with sudden irritation. A recent investigation traced this puzzling behavior back to their wild ancestry.
Domestic cats have been living alongside humans for roughly four millennia, yet their DNA remains strikingly similar to that of the African wildcat, their untamed forebear. While we humans tend to show affection through touch, the African wildcat is a solitary animal that actively avoids close contact with its own kind.
The researchers propose a simple solution.
When a cat takes the initiative to bond, it prefers to be in the driver’s seat, metaphorically speaking. In those moments, cats allow owners to extend physical affection for longer periods. They particularly relish having their chins, ears, and cheeks stroked, while they are less fond of having their backs, bellies, or the base of their tails touched.
Owners should stay vigilant for any negative body‑language cues from their whiskered companions and back off when needed. Ultimately, the key lies in honoring each cat’s lingering wild instincts while offering affection on their terms.
9 Canned Laughter Helps Bad Comedy
Television critics have long dismissed laugh tracks as antiquated relics that belong to an era of subpar acting and stale storylines. Yet viewers continue to rely on those canned giggles as a cue that something is meant to be funny.
In 2019, investigators selected 40 notoriously bad jokes and asked participants to evaluate them under three conditions. First, 20 students heard the jokes without any pre‑recorded laughter, resulting in predictably low scores—none rose above a 3.75 on a seven‑point scale.
Subsequently, 72 adults rated the same jokes three times: once with no laughter, once with obvious, forced laughter, and finally with genuine, spontaneous laughter. The forced track nudged ratings upward by roughly ten percent, but the most striking boost—between fifteen and twenty percent—occurred when volunteers heard authentic, enthusiastic laughs.
The researchers suggest that this uplift stems from humanity’s deep‑seated response to laughter as a primitive social signal. In other words, we are more inclined to enjoy a joke when we sense that others are collectively sharing the amusement.
8 Tempting People With Wallets
Back in 2015, a cadre of behavioral scientists set out to probe the honesty of civic workers around the globe. Their mission involved traveling to 40 countries and distributing more than 17,000 wallets stuffed with cash, credit cards, and a few hundred keys.
Research assistants masqueraded as tourists who “found” a wallet and handed it to staff members at banks, museums, police stations, and other public institutions, requesting that the employee locate the wallet’s owner.
The experiment aimed to answer two questions: Do certain nations exhibit higher rates of wallet return, and does the amount of money inside sway the decision?
When the findings were published in 2019, they upended the expectations of 300 seasoned economists who had predicted that larger sums would tempt more theft. Instead, the data revealed that participants were actually more likely to return wallets that contained more cash, and the country of origin made no discernible difference.
7 Phone Movements Reveal Personality
One trusted method for assessing personality involves the classic Big Five questionnaire, which gauges openness, extraversion, agreeableness, conscientiousness, and neuroticism.
Starting in March 2010, researchers tracked 52 volunteers for over a year, exploring a novel angle: could a person’s smartphone usage patterns serve as a proxy for the Big Five traits?
Each device was equipped with an accelerometer to capture physical movements, while custom software logged calls and messages. When the researchers compared these metrics to participants’ self‑reported Big Five scores, they discovered notable overlaps.
The data proved especially adept at predicting extraversion, conscientiousness, and neuroticism—traits that tend to manifest in more vigorous physical activity. Conversely, the method fell short for openness and agreeableness, likely because those traits are less tied to overt motor behavior.
6 Spiders On Drugs
In 1948, German zoologist H.M. Peters grew frustrated with the nocturnal habits of orb‑web spiders he was studying at the University of Tübingen. To observe their web‑spinning, he had to rise at ungodly hours between two and five in the morning.
He enlisted pharmacologist Peter Witt to experiment with substances that might shift the spiders’ active period. Witt prepared a sugar‑water mixture laced with caffeine, amphetamine, mescaline, strychnine, or LSD, hoping the chemicals would delay the spiders’ web‑building to more convenient times.
While the drug‑infused spiders indeed altered the size and pattern of their webs, they stubbornly continued to spin during the early morning hours. Peters eventually abandoned the project, but Witt pressed on, conducting further trials.
In 1995, NASA replicated Witt’s experiments, this time feeding spiders caffeine, marijuana, speed, and chloral hydrate. The spiders produced distinctly altered web designs depending on the compound consumed.
The degree of web deformation correlated with the toxicity of the drug, suggesting that spiders could serve as a low‑cost, humane model for testing poisonous substances, potentially reducing reliance on mammalian subjects.
5 Chocolate Extinction
Chocolate lovers were alarmed when headlines warned that their beloved treat could vanish by 2050. The threat stems from mounting pressures on cacao trees, the plant that yields cocoa beans.
Multiple studies have tracked fungal diseases ravaging Central American cacao plantations, and they warn that these pathogens could spread to the remaining cacao regions worldwide. Climate change compounds the danger by fostering harsher weather patterns that stress the trees.
Adding urgency, half of the global chocolate supply originates from just two African nations—Ghana and the Ivory Coast. Should climate shifts impair production in these countries, the entire industry could face a severe shortfall.
Cacao trees thrive in stable, humid rainforest conditions and are highly sensitive to temperature fluctuations. Projections for 2050 anticipate higher temperatures and increased dryness, conditions that could cripple chocolate production.
Scientists are investigating genetically fortified cacao varieties to bolster resilience, though such modifications may alter the traditional, natural profile of chocolate that consumers cherish.
4 Climate Apartheid
A 2019 study introduced the chilling concept of “climate apartheid,” a scenario where climate change fractures humanity into two distinct classes: those who can afford protection and those who cannot.
The United Nations Human Rights Council compiled findings from over a hundred investigations, all pointing to the dire ways climate change threatens fundamental human needs—housing, food, water, and health.
The report warned that, as conditions deteriorate, the wealthier segment of the population will retreat into fortified enclaves, while the poorer majority will face famine, disease, and displacement.
Without a rapid, radical shift in environmental policy and immediate safeguards for the most vulnerable, millions could perish. Ironically, those most at risk live in the poorest nations, which have contributed the least to the greenhouse gases driving climate change.
3 Anxiety Makes Godzilla Grow
In 2019, scientists turned their attention to the escalating size of Godzilla across cinematic history. The monster stood at a modest 50 meters (164 ft) in the 1950s, but by the 2019 reboot, it towered at 120 meters (393 ft)—a growth rate far beyond any known organism.
The researchers explored several explanations and concluded that Godzilla’s expanding stature serves as a metaphor for collective human anxiety. Societal pressures such as political turmoil, environmental crises, and personal stressors fuel the monster’s symbolic growth.
They argue that Godzilla embodies the massive challenges humanity must confront together—climate change, terrorism, and other existential threats. At the same time, the creature’s ever‑larger presence may simply reflect audience demand for ever‑bigger spectacle.
2 An Unknown Shape
Epithelial cells line our skin, line organs, and guide embryonic development, yet scientists long assumed their geometry resembled simple tubular prisms or frustum‑shaped structures.
In 2018, a team of researchers turned to computational modeling to uncover the true shape of these cells. Their analysis revealed an entirely novel geometric form that had never before been catalogued in mathematics.
The newly identified shape, dubbed the “scutoid,” resembles a Y‑shaped prism: one branch terminates with five surfaces, the other with six. This configuration appears to enable epithelial cells to pack together efficiently while bending around curved tissue.
Beyond adding a fresh entry to the lexicon of geometry, the discovery holds promise for tissue engineering. Understanding how scutoids assemble could improve the design of artificial organs destined for transplantation.
1 The Common Cold Beat Cancer
For decades, scientists have entertained the notion of using viruses to attack cancer cells, but it wasn’t until 2019 that a concrete proof‑of‑concept emerged. Researchers enrolled 15 patients with early‑stage bladder cancer and introduced coxsackievirus A21—a virus that typically causes the common cold—directly into their bladders via catheter.
Each participant’s catheter remained in place for an hour, allowing a higher concentration of the virus to flood the tumor site than would occur during a natural infection. After the viral infusion, the patients underwent surgical removal of their tumors.
Remarkably, the cold virus inflicted severe damage on many of the tumors and summoned a swarm of immune cells to join the assault. In one standout case, the virus eradicated the tumor entirely.
Overall, the study suggests that a benign, naturally occurring virus can be harnessed to bolster cancer treatment without causing the patients to develop actual cold symptoms.
