WTF Fun Fact 13489 – Most Orangutans are Left Handed

by

If you’re a lefty, you have more in common with an orangutan than just 97% of your DNA since most orangutans are left-handed too. One neuroscientist, Bill Hopkins, said his research showed around 66% of orangutans to be lefties.

Studying Handedness in Orangutans

Curiosity sparked the investigation into orangutan handedness. Scientists found themselves wondering – do these creatures prefer one hand over the other, like us humans? It’s something we’ve all thought about, right? No? Ok, well anyway.

Researchers observed orangutans in their natural and semi-natural habitats. Hopkins appears to be the only one who suggested the specific 66% number. But plenty of other research has found that while some primates like chimpanzees and bonobos (our closest relatives) tend to be right-hand dominant, gorillas and orangutans are not.

What Does it Mean that Most Orangutans are Left-Handed?

Just like in humans, an orangutan’s hand preference comes from the brain. We call it “cerebral lateralization” – a fancy term for one side of the brain being bossier than the other.

The left hemisphere controls right-handedness, and the right hemisphere oversees left-handedness. Both genes and environment play a part in this.

But a mystery remains. Why do orangutans tend to be left-handed more often when compared to humans and other great apes?

Out in the wild, being left-handed doesn’t make the orangutans any less skillful. They foraged for food, made comfy nests, and swung from tree to tree with aplomb. Whether peeling fruit or brachiating through the forest, left-handed orangutans showed no signs of struggle.

Now here’s an intriguing question. We humans share 97% of our DNA with orangutans, so why aren’t more of us left-handed? Researchers are keen on finding an answer. They hope to understand how and why hand preference might have shifted during human evolution.

Orangutans, like us, are social animals. They have a rich array of communication methods at their disposal. This research is igniting interest in the connection between left-handedness and communication. Also, it has made scientists curious about the potential link between hand preference and cognitive abilities.

A Curious Conclusion

The higher percentage of left-handedness in orangutans adds an exciting twist to our understanding of these creatures. It opens up a new avenue for exploration: Why this hand preference? How does it affect their survival, adaptation, and mental prowess?

Researchers are now actively trying to link left-handedness to the species’ behavior and neural traits. They’re also excited to understand how this discovery could shape our understanding of human evolution.

WTF Fun Fact 13488 – Police Training in Norway

by

Police training in Norway is notorious rigorous. Unlike many countries where law enforcement training involves a few months in a police academy, Norway makes a three-year commitment at the Police University College (Politihøgskolen) a must.

Norway’s Police University College

Yes, you read that right – a university college just for police training. The Police University College, situated in Oslo, Stavern, and Kongsvinger, is the heart of Norway’s police education system.

Aspiring officers embark on a three-year bachelor’s degree program where they learn far more than just the basics of policing. The curriculum is thorough and multi-faceted, including subjects like law, ethics, criminology, and even foreign languages.

The first and third years of the bachelor’s program mainly focus on theoretical studies. Cadets dig deep into the theory of police work, criminal law, ethics, and social sciences. They are taught to respect human rights, to understand different cultures, and to uphold justice without bias. This holistic approach ensures that the officers graduate with a comprehensive understanding of both the practical and societal aspects of their role.

Field Training for Norwegian Police

What good would theoretical knowledge be without some practical application? That’s why the second year is dedicated to field training. Cadets spend this year across various police districts, getting their boots dirty and experiencing the real-world scenarios they’ve learned about in class. This year is invaluable, bridging the gap between theory and practice and providing hands-on experience in the field.

Norwegian police officers aren’t just confined to their patrol cars. Some have prosecutorial powers, handling minor offenses in court. This unique responsibility requires additional qualifications – a law degree, to be precise. Hence, those who wish to take on this dual role undertake further education, adding an extra layer of legal expertise to their enforcement abilities.

The Ethical and Emotional Aspects of Police Training in Norway

Police work can be as mentally challenging as it is physically, if not more. Norway understands this and includes psychological training to build resilience and mental fortitude. Ethical training is another cornerstone, ensuring officers know how to react respectfully and responsibly in every situation.

It’s clear that the journey to becoming a police officer in Norway is a commitment to rigorous education, intense field training, and personal development. It’s about shaping individuals who are not just law enforcers, but educated, empathetic, and ethical members of the community they serve.

WTF Fun Fact 13487 – Happy Couples Post Less on Social Media

by

We’re all familiar with that couple who constantly posts pictures of their romantic getaways, perfect dinners, and seemingly idyllic moments – but a study showed that happy couples post less on social media.

It appears that couples who frequently share selfies and other relationship-related content on social media platforms aren’t living quite the life they claim to be. Go figure.

The Study and Its Findings

An online photography platform, Shotkit, conducted an intriguing study involving over 2,000 individuals aged between 18 to 50. The participants were asked to rate their relationship’s overall happiness, intimacy, communication, and trust. They were also asked about their frequency of sharing relationship-related content on social media.

The study revealed that couples who posted three or more selfies per week were, on average, 128% less happy compared to those who refrained from broadcasting their relationship on the internet. In fact, only 10% of frequent social media sharers categorized themselves as “very happy.”

In contrast, nearly half (46%) of those who don’t publicize their relationships online perceived themselves as happier. The unhappiest group was couples who posted more than three times a week, with merely 32% classifying their relationship as “happy” or “very happy.”

Reasons Happy Couples Post Less on Social Media

This study’s findings hint at potential underlying issues. One compelling inference is that trust issues could be prompting couples to post more frequently on social media. The main reason identified for couples sharing their relationship online was to signify that they or their partner were ‘taken.’

Interestingly, the top three reasons why couples refrained from sharing their relationships online were: “privacy,” “embarrassment,” and being “not regular social media users.”

Of course, not all social media sharing is detrimental but hinted at the danger of overdoing it.

The results suggest a potent social media paradox. In a world where social platforms allow us to share our lives with a broader audience, we might unknowingly be sacrificing the intimacy and privacy that nourish a truly fulfilling relationship.

WTF Fun Fact 13486 – Mamihlapinatapai, the Most Succinct Word

by

Certain words defy easy translation since they embody ideas or emotions so complex – one such word is “mamihlapinatapai.”

This word hails from the Yaghan language of Tierra del Fuego, an archipelago split between Chile and Argentina. The term was recognized in the 1994 Guinness Book of World Records as the world’s most “succinct word.” (Unfortunately, today, their tribe has dwindled to fewer than 2,000 members, with most speaking Spanish instead of their native tongue.)

Mamihlapinatapai, the Untranslatable Emotion

Mamihlapinatapai is defined as “a look shared by two people, each wishing that the other would initiate something that they both desire but which neither wants to begin.”

The word’s complexity and its lack of a direct translation into English or other major languages have earned it a spot among the world’s favorite “untranslatables.”

It wasn’t until the late 2000s that the term mamihlapinatapai started appearing all over the internet. People were fascinated. Artists found inspiration in the term, incorporating it into their songs, exhibitions, and books.

More Than Just Romance

Of course, just as internet fame changes a person, it can change a word. While mamihlapinatapai often evokes romantic notions, its application now extends to other areas. For example, in gaming theory, it refers to the volunteer’s dilemma, where an individual player might have to make a sacrifice for the collective benefit.

Despite the global recognition of mamihlapinatapai, the Yaghan language is teetering on the brink of extinction. It has no linguistic relatives. The last guardian of this language is Cristina Calderon, the only fluent living speaker of Yaghan!

Despite the impending threat to the Yaghan language, there’s hope. Calderon has been teaching her granddaughter some Yaghan, and they have published books to preserve Yaghan culture and history. This effort to pass on the language and culture to the next generation is a critical step in preserving this endangered language.

Internet Fame: A Blessing or a Curse?

While the global recognition of mamihlapinatapai has introduced the world to the Yaghan language and culture, it has also brought unwanted media attention to the Yaghan community. The fame of a single word, however, does not ensure the survival of the language.

The story of mamihlapinatapai is a testament to language’s ability to capture the subtleties of human experience. It serves as a stark reminder of the loss we face as languages dwindle and disappear, taking with them unique cultural perspectives and understanding.

The tale of this word reminds us that each language offers its unique prism through which we can view and understand the world.

WTF Fun Fact 13485 – People Who Read Live Longer

by

In 2016, Yale researcher first published a study that found a connection between longevity and reading – in other words, people who read live longer. It’s a correlation, but there’s no clear causation (that is, there’s no proof that reading is precisely what adds years to your life). Still, it felt validating for those of us who love the written word. And even better, it’s a free activity (if you have access to a library) that’s available to lots of people!

So, Do People Who Read Live Longer?

In an increasingly digitized world, it might be easy to dismiss reading as a leisurely pastime of bygone eras. Yet, plenty of people still do it. So, researchers from Yale University’s School of Public Health decided to expore the benefits of reading to try and understand whether engaging in this mental exercise could have real, tangible effects on longevity.

The study analyzed data from 3,635 individuals aged 50 and above. It divided them into three groups.
1) those who didn’t read books
2) those who read for up to three and a half hours a week,
3) and those who read more than that.

The results? Book readers, regardless of gender, wealth, education, or health, had a 20% reduction in risk of mortality over a 12-year period compared to non-book readers!

Even reading less than 3.5 hours per week benefitted. Reading came with a significant survival advantage over those who didn’t read at all.

Why Does Reading Enhance Longevity?

The exact mechanisms that would explain why people who read live longer are still being explored. But the hypothesis is as fascinating as the result itself.

Reading books, particularly those with complex narratives, demands cognitive engagement and promotes empathetic understanding and emotional intelligence. This intellectual stimulation boosts brain power, much like how physical exercise strengthens the body.

Reading can also provide a healthy form of escapism, reducing stress, and promoting better mental health. This “workout” for the mind might increase resilience against age-related cognitive decline and diseases, leading to an overall longer lifespan.

Not All Reading Is Equal

While all reading is beneficial, the study found that reading books, as opposed to magazines or newspapers, provided a larger survival advantage. This could be because books involve more immersive and cognitive processes, like the use of imagination and critical thinking. They also encourage the reader to make connections between different plot elements spread out over hundreds of pages, creating a greater neural stimulus.

We know what you’re wondering. We’re wondering about it too. What about reading online or on an e-reader? And researchers aren’t sure. But older research found that people who read physical books were more engaged and remembered more plot points. However, we need more research – and those results wouldn’t apply to everyone anyway.

Further research is needed to solidify the connection and understand the exact mechanisms behind why people who read live longer. For instance, how different genres might impact longevity is still an open question. Does a suspense thriller provide the same benefit as a heartfelt romance?

And, of course, as digital reading becomes more popular, future research will need to explore whether reading eBooks – or even listening to audiobooks – provides the same benefits as “traditional reading.”

WTF Fun Fact 13484 – Robots That Feel

by

Robots that feel?! Ok, no. We don’t mean robots that have feelings. We mean robots that have a “sense” of touch. Or at the very least robots programmed not to crush things they pick up. That’s still progress!

The modern robotics field is continuously pushing the boundaries of technology and automation. As a part of this ongoing exploration, scientists from the Queen Mary University of London, alongside their international colleagues from China and USA, have developed an innovative, affordable sensor called the L3 F-TOUCH. This unique invention enhances a robot’s tactile abilities, granting it a human-like sense of touch.

Robots That Feel Thanks to the L3 F-TOUCH Sensor

A principal objective in robotics has been achieving human-level dexterity, specifically during manipulation and grasping tasks. The human hand’s ability to sense factors such as pressure, temperature, texture, and pain, in addition to distinguishing objects based on properties like shape, size, and weight, has set the standard.

Until now, many robot hands or graspers have fallen short, lacking these vital haptic capabilities. As you might imagine, this makes handling objects a complicated task. Robots’ fingers lack the “feel of touch,” resulting in objects slipping away or being unintentionally crushed if fragile. And that’s not something we want if we’re ever going to let them work with people, like the elderly.

Mechanics and Functionality

Leading the groundbreaking study, Professor Kaspar Althoefer of Queen Mary University of London and his team, introduces the L3 F-TOUCH. The name stands for Lightweight, Low-cost, and wireless communication. It’s a high-resolution fingertip sensor that directly measures an object’s geometry and the forces necessary to interact with it.

This sensor sets itself apart from others in its league that estimate interaction forces via camera-acquired tactile information. The L3 F-TOUCH takes a direct approach, achieving a higher measurement accuracy.

Professor Althoefer and his team plan to further enhance the sensor’s capabilities. They aim to add rotational forces such as twists, vital in tasks like screw fastening.

These advancements could extend the sense of touch to more dynamic and agile robots, improving their functionality in manipulation tasks and even in human-robot interaction settings, such as patient rehabilitation or physical support for the elderly.

WTF Fun Fact 13483 – Lifespan of a Cat Increasing

by

The average lifespan of a cat (well, an indoor cat) is around 12 to 15 years, but many cats now can live to be 20. These numbers seem to be trending upward. (Although we have to admit that we haven’t seen this confirmed by researchers anywhere – the evidence appears to be anecdotal).

Factors Influencing the Lifespan of a Cat

Today’s cats appear to be living longer, healthier lives. This is aided by advancements in veterinary medicine and growing awareness about the importance of preventive care.

From lifestyle choices to genetics, every aspect has an influence on how long our fur-buddies can thrive. The following are some of the most significant contributors:

Indoor Versus Outdoor Cats

Like humans, cats’ lifestyles profoundly affect their longevity. It’s no secret that indoor cats tend to live longer than their outdoor counterparts. They are shielded from various risks like diseases, accidents, predators, and harsh weather

The protected environment ensures they enjoy a higher average lifespan, usually about 15-20 years. In stark contrast, outdoor cats face myriad threats that can often cut their lifespan to just 2-5 years.

Preventive Care

Preventive care, like routine check-ups, vaccinations, and flea and tick preventatives, plays a key role in cat longevity. Regular veterinary examinations can help detect potential health problems early, improving the odds of successful treatment.

Early diagnosis and treatment can be life-saving, especially for chronic conditions like kidney disease, common in cats.

Diet and Weight Management

Another significant factor influencing cat lifespan is diet and weight management. Proper nutrition is crucial for the overall well-being of cats. A balanced diet containing all necessary nutrients contributes to longevity.

On the other hand, obesity is a severe issue that can lead to various health problems like diabetes, arthritis, and heart diseases, reducing a cat’s lifespan.

This is starting to sound a lot like people…or any other living thing, really. Don’t play in the road, eat healthy, get exercise, see a doctor when you’re sick…

Genetics and Breeds

Genetics and specific breed characteristics can influence how long a cat lives.

Some breeds are prone to specific health conditions that can affect their lifespan, while others are generally known for their longevity. For instance, Siamese and Maine Coon cats often live well into their teens, with many reaching their early 20s.

The Lifespan of the Oldest Cat

Now, all of this talk of health might have you thinking that it’s the only way to live a healthy life. But let’s think about humans for a moment. Ever read an interview with someone over 100 who insists the secret is bacon or cigarettes or something? Some of this is just random.

The oldest cat on record, Creme Puff, was well-cared for though. She was an astonishing 38 years and 3 days at her death. Her owner also owned the previous oldest living cat! The secret? Some things you really aren’t supposed to give a cat – like caffeine. The diet fed to these cats was largely commercial cat food with some eggs, turkey bacon, broccoli, coffee with creme, and an eye dropper of ref wine every two days!

Don’t try that at home, but maybe do take the owner’s advice to play with your cat as much as possible if you want them to live a long and active life.

WTF Fun Fact 13482 – GPT-3 Reasoning Skills

by

Research from UCLA psychologists has discovered a surprising new contender in our analogical reasoning battles – the artificial intelligence language model, GPT-3. Apparently, it holds its own against college undergraduates on reasoning problems typical of intelligence tests and the SAT.

But it fails to answer a key question: Is GPT-3 merely parroting human reasoning, or has it stumbled onto a brand-new cognitive process? (And, does this research say more about technology, college students, or intelligence tests?!)

Humans vs GPT-3

OpenAI holds GPT-3’s secrets under tight wraps, so they aren’t going to be much help in figuring out how the algorithm works its “magic.” Despite the mystery, the UCLA researchers found that GPT-3 outperformed their expectations on some tasks. Yet, other tasks saw it crash and burn.

Despite its ability to embarrass some college students, the study’s first author, Taylor Webb, emphasized GPT-3’s limitations. While it excels at analogical reasoning, it fails spectacularly at tasks simple for humans, like using tools to solve physical problems.

Webb and his colleagues tested GPT-3 on problems inspired by Raven’s Progressive Matrices. They translated the visual problems into text and gave the same problems to 40 UCLA undergraduate students.

Not only did GPT-3 perform as well as humans, but it also made similar mistakes.

What the Study Results Mean

GPT-3 solved 80% of the problems correctly, while the human average score was below 60%. The team then tested GPT-3 with SAT analogy questions they believed had never been on the internet (which would mean they weren’t part of the GPT training data). Again, GPT-3 outperformed the average college applicant’s score (then again, we know these tests aren’t really a measure of intelligence).

However, when the researchers tested the program against student volunteers on analogy problems based on short stories, GPT-3 struggled.

And tasks that require understanding physical space continue to baffle the so-called “artificial intelligence.”

“No matter how impressive our results, it’s important to emphasize that this system has major limitations,” said Taylor Webb, the study’s first author. “It can do analogical reasoning, but it can’t do things that are very easy for people, such as using tools to solve a physical task. When we gave it those sorts of problems — some of which children can solve quickly — the things it suggested were nonsensical.”

WTF Fun Fact 13481 – Shanidar 1

by

Shanidar 1, affectionately known as “Nandy” to some, lived approximately 45,000 to 35,000 years ago. His Neanderthal remains, found in Iraq’s Shanidar Cave, provide researchers with a wealth of information about Neanderthal life and society. These findings challenge our preconceptions and encourage a fresh understanding of our ancient relatives.

The Life of Shanidar 1

American archaeologist Ralph Solecki and his team discovered Shanidar 1 during excavations from 1957 to 1961. The cave, located in the Zagros Mountains, held a plethora of archaeological treasures. The team unearthed remains of eight adult and two infant Neanderthals, identifying Shanidar 1 first.

Shanidar 1’s remains reveal a life of hardship and resilience. He was an older adult, likely around 40-50 years old when he died, an advanced age for a Neanderthal. Remarkably, Shanidar 1 suffered several injuries and health issues. His right arm withered, likely due to nerve damage, and he probably lost the use of it several years before his death. He also had a damaged left eye that might have caused blindness. Signs of a significant blow to his face suggest that he lived with considerable pain.

Shanidar 1’s traumas and his survival into adulthood suggest that Neanderthal societies likely provided social care. His disabilities would have made self-care and hunting difficult, so it’s plausible that his group cared for him. This observation challenges previous notions of Neanderthals as primitive beings and suggests a society with empathy and cooperative care.

Understanding Neanderthal Health

Shanidar 1’s remains also offer insights into Neanderthal health. He displayed significant wear and tear, such as degenerative joint disease, likely common in Neanderthal populations due to a physically demanding lifestyle. His dental health, with several lost and worn teeth, hints at the Neanderthal diet, which was probably abrasive and tough.

Shanidar 1’s discovery in the cave sparked interest in Neanderthal burial practices. Pollen found around his body hinted at the possibility of a burial ritual with flowers, though this interpretation has sparked debate. Despite the controversy, the idea has become popular, creating an image of Neanderthals as “flower-buriers,” capable of symbolic thought and ritualistic behavior.
