WTF Fun Fact 13742 – Humming While Holding Your Nose

Ever tried humming while holding your nose? Spoiler alert: it doesn’t work, and here’s why.

The Mechanics of Humming While Holding Your Nose

Humming involves sound produced by vocal fold vibrations in your throat. Normally, when you hum, the sound exits through your nose. Yes, your nose is more than just a place to hang glasses or catch a cold; it’s a vital part of your vocal instrument.

When you hum, your mouth stays closed, so the only exit route for the air is through your nasal passages. This airflow through the nose helps to amplify and modify the sound, creating that familiar humming tone.

What Happens When Try Humming While Holding Your Nose

So, what goes down when you clamp shut your nostrils? Simply put, you block the only air escape route. When your nose is pinched shut, the air that vibrates in your vocal cords can’t escape your body easily. This disruption stops the sound from developing into a hum.

Trying to hum with your nose closed might make you feel a bit silly as you realize no sound comes out. Instead, you might just hear a muffled, nasal sound or nothing at all. It turns out that your body can’t outsmart the basics of sound physics, no matter how hard you try.

A Dive into the Science of Sound

Humming is a demonstration of sound waves being carried through air. When these waves have a clear path to travel, you hear the hum loud and clear. Block that path, and the sound waves get stifled. This is basic physics in action, showing how sound transmission needs a medium (like air) to travel effectively.

When you hold your nose and attempt to hum, you’re essentially trapping the sound waves in your head. Since they can’t escape or be properly projected, the humming just doesn’t happen.

Fun Experiments and Party Tricks

Next time you’re at a party and run out of small talk, why not pull out the “try to hum with your nose pinched” challenge? It’s a fun, quirky trick that can break the ice and spark a conversation about the weird and wonderful ways our bodies work.

Humming with your nose pinched is one of those things that sounds like it might be possible until you actually try it. It’s a neat demonstration of how interconnected our bodily functions are—even something as simple as humming involves multiple parts of our respiratory and vocal systems.

WTF Fun Fact 13740 – The Vatican Regulates the Divine

The Vatican introduced a new set of guidelines aimed at scrutinizing claims of supernatural phenomena more rigorously. From weeping statues to miraculous healings, the Catholic Church is setting the bar high for what passes as a divine occurrence.

The Vatican’s Dicastery for the Doctrine of the Faith, responsible for promoting and safeguarding doctrine, has crafted these rules. They replace the older guidelines from 1978, marking a significant update in how the Church handles these mysterious claims.

A Call for Rigor and Rationality at the Vatican

At a media briefing last Friday, the Vatican made its stance clear: supernatural claims must undergo a thorough investigation to prevent fraud and exploitation. The Church aims to protect its credibility and unity, steering clear of scandals that could tarnish its image.

In an era where viral news can spread falsehoods in an instant, the guidelines stress the importance of careful validation. Reports of supernatural events have surged, propelled by the rapid spread of information online. The new protocol includes issuing a “nihil obstat,” meaning “no obstacle,” for unverified but harmless claims, allowing worship without formal recognition of the supernatural.

The Vatican’s Verdicts

Under the updated rules, bishops can make one of six decisions regarding supernatural claims. These range from outright rejection to prohibiting the worship associated with certain phenomena. To ensure consistency, bishops must seek approval from the Vatican before going public with any supernatural endorsements, with the Pope stepping in for exceptional cases.

This rigorous approach is not about stifling faith but about safeguarding it from the distortions of modern myth-making. The Vatican recognizes the powerful draw of pilgrimage sites, like Lourdes in France and Fatima in Portugal, where millions visit annually, drawn by tales of Marian apparitions and miracles recognized by the Church decades ago.

The Challenge of Modern Miracles

Not all supernatural claims make the cut. Take the 2016 incident in Italy, where a woman claimed regular visions of Jesus and Mary. It took eight years for the Church to investigate and dismiss the claims, which included contentious messages on social issues like same-sex marriage and abortion. This case underscores the challenges the Church faces in distinguishing genuine spiritual phenomena from well-crafted hoaxes.

The new guidelines aim to streamline this process, ensuring that any claim of a heavenly apparition or miraculous event receives the scrutiny it deserves before being accepted or rejected.

WTF Fun Fact 13734 – Bigger Brains, Longer Yawns

Researchers have discovered that vertebrates with larger brains and more neurons tend to have longer yawns. This fascinating correlation sheds light on the complexity of yawning and its ties to brain function.

Yawning involves a deep inhalation followed by a slow exhalation, stretching the jaw and increasing blood flow to the brain. This process helps cool the brain, promoting alertness and cognitive function. The duration of a yawn appears linked to the brain’s size and neuron count, making it more than just a sign of boredom or tiredness.

The Science Behind Yawning

Scientists have studied yawning across various species to understand its role and significance. Research shows that yawning increases with brain size and neuron density. Vertebrates, like mammals and birds, exhibit yawning behaviors, with larger-brained species showing notably longer yawns.

Yawning likely serves to regulate brain temperature and promote alertness. When we yawn, the stretching of the jaw and the intake of cool air help reduce brain temperature. This cooling effect can enhance cognitive function, making yawning an essential mechanism for maintaining brain efficiency.

Studies suggest that longer yawns in larger-brained vertebrates may facilitate more effective brain cooling. The increased neuron density in these animals requires more robust cooling mechanisms to maintain optimal brain function. Thus, a longer yawn duration could be an adaptive trait to support the needs of a more complex brain.

Comparative Yawning Across Species

Research comparing yawning durations among different species reveals intriguing patterns. For instance, humans, with relatively large brains and high neuron counts, have yawns lasting around six seconds. In contrast, smaller-brained animals, like mice, have yawns lasting just one to two seconds.

Birds also demonstrate this trend, with larger species, such as owls, exhibiting longer yawns than smaller birds, like sparrows. This pattern supports the idea that brain size and neuron density influence yawn duration across vertebrates.

The correlation between brain complexity and yawning duration highlights the evolutionary significance of this behavior. Yawning may have evolved to enhance brain function, particularly in species with larger, more complex brains. This adaptive mechanism likely provides a selective advantage by supporting higher cognitive abilities and alertness.

Longer Yawns and Brain Health

Understanding the link between yawning and brain function has implications for brain health research. Yawning could serve as an indicator of brain activity and cognitive function in both humans and animals. For example, changes in yawning frequency or duration could reflect alterations in brain health or function.

In humans, excessive yawning may signal underlying medical conditions affecting the brain, such as multiple sclerosis or brain injury. Conversely, reduced yawning could indicate diminished brain function or alertness. Monitoring yawning patterns could thus provide valuable insights into brain health and function.

Furthermore, studying yawning in animals can enhance our understanding of their cognitive abilities and brain function. By analyzing yawning behaviors, researchers can gain insights into the neural and physiological mechanisms underlying brain function across different species.

WTF Fun Fact 13666 – Sniffing Women’s Tears

Recent groundbreaking research has uncovered a fascinating facet of human interaction: the power of women’s tears to reduce aggressive behavior in men.

The study explores social chemosignaling—a process well-documented in animals but lesser-known in humans. The findings, published in PLOS Biology, suggest that emotional tears from women contain chemicals that significantly diminish aggression-related brain activity and behavior in men.

The Study: Exploring the Influence of Women’s Tears

The researchers embarked on a unique experiment, exposing a group of men to women’s emotional tears and saline solution, both odorless, while engaging them in a two-person game designed to provoke aggressive responses. The players believed they were competing against a cheating opponent and had the chance to retaliate by financially penalizing them.

Intriguingly, when these men were exposed to women’s tears, their tendency to seek revenge plummeted by over 40%.

Brain Activity and Behavioral Change

The study didn’t just stop at observing behavioral changes; it also examined how the brain reacts to these chemical signals. When the experiment was conducted within an MRI scanner, it revealed significant findings. Two critical aggression-related areas in the brain—the prefrontal cortex and anterior insula—showed heightened activity during provocation.

However, this activity was noticeably subdued when the men sniffed the tears. The connection between reduced brain activity in these regions and decreased aggressive behavior was unmistakable.

This research is more than just an academic curiosity; it has profound implications for understanding human interactions and the subtle ways we influence each other’s behaviors.

The fact that a simple, invisible chemical in women’s tears can have such a tangible effect on men’s aggression is a testament to the complex and nuanced nature of human communication and social relationships.

This challenges the previously held belief that emotional tears are a uniquely human trait without a functional purpose.

Exploring Tears

While this study opens up a new avenue in understanding human behavior, it also raises numerous questions. What specific chemicals in tears influence aggression? Are there other emotional states or signals that can similarly affect behavior? How does this chemosignaling interact with other forms of communication?

As researchers continue to explore these questions, we can expect to uncover even more about the intricate tapestry of human emotions and interactions.

WTF Fun Fact 13652 – The Grey Hulk Origin

Do you know the grey Hulk origin story? Wait…did you even know there was once a GREY Hulk?

The Incredible Hulk, known for his iconic green skin and colossal strength, didn’t start off green. In 1962, Marvel Comics debuted the Hulk as a grey-skinned goliath.

Created by Stan Lee and Jack Kirby, the Hulk was envisioned as a misunderstood creature, akin to Quasimodo or Frankenstein’s monster. The aim was to make him relatable and devoid of any specific ethnic association.

The Unplanned Transition to Green from the Grey Hulk Origin

During the initial comic series, the colorist faced challenges with the grey ink. This inconsistency led to the Hulk’s skin appearing green in some editions. Interestingly, Stan Lee embraced this accidental green hue, and it became a defining feature of the Hulk’s character. Interestingly, the serendipitous twist gave the Hulk a distinct and now-iconic appearance.

In the world of comics, changes often get woven into the storyline. The Hulk’s color change was explained as a consequence of ongoing gamma exposure affecting Bruce Banner, the Hulk’s alter ego. As a result, the simple narrative device allowed the transition from grey to green to fit seamlessly into the Hulk’s story.

The Emergence of Grey Hulk’s Persona

The Hulk’s color change wasn’t just cosmetic. It introduced a new aspect to Bruce Banner’s persona. The Grey Hulk, also known as Joe Fixit, was an intelligent, calculating figure, quite different from the savage and primal Green Hulk. As a result, the new identity even saw the Grey Hulk working as a gangster in Las Vegas, showcasing a complex character far removed from the original concept.

Bruce Banner’s struggle with his dual identities led to a significant storyline involving therapy sessions with Doc Sampson. These sessions aimed to integrate Banner’s personalities. Eventually, they led to the creation of “The Professor,” a persona where Banner’s intellect controlled the Hulk’s strength. This concept found its way into the MCU’s “Avengers: Endgame,” where Banner and the Hulk merge into a single entity, illustrating how the character has evolved over the years.

The Impact of a Coloring Error

The Hulk’s journey from grey to green highlights how creative decisions can shape a character’s legacy. What began as a coloring issue led to an iconic change that deeply influenced the Hulk’s character development. This change not only established the Hulk’s visual identity but also paved the way for exploring multiple facets of Bruce Banner’s personality.

WTF Fun Fact 13556 – Quebec’s Civil Code

Since 1981, Section 393 of Quebec’s Civil Code has forbidden women from legally taking their husbands’ surnames post-marriage.

Quebec established the law to combat societal pressure on women and to promote gender equality. However, not all women agree with the law and some find it restricting.

With this law, a woman’s maiden name remains her legal name after marriage, and she cannot change it without the authorization of the court—which isn’t an easy task.

A married couple may hyphenate each other’s surnames, and women can call themselves whatever name they’d like in an unofficial capacity. But only their birth name is legally recognized by law.

Quebec’s Civil Code Intent and Reception

The law’s primary intent was to protect women from societal pressures and ensure their freedom. However, as Dubé notes, it’s a delicate balance between protecting and improving freedom. Exceptions to the law exist, but they are rare and only apply in extreme cases. This rigidity applies even to Canadian women who relocate to Quebec after marrying in other provinces.

Sophie Grégoire-Trudeau, Canada’s de facto first lady, recently used a hyphenated version of her name, igniting a discussion on this topic. Despite the legal stipulations, she chooses to use both her maiden name and her husband’s surname, symbolizing her personal identity and partnership.

For many Quebec women retaining their birth names may be a significant aspect of their cultural identity. This practice signifies autonomy and self-belonging.

Cultural Shifts and Modern Perspectives

Over the years, Quebec’s approach to married names has influenced cultural norms, including the trend of parents giving children two last names. While this was popular for a time after the 1981 law, its prevalence has decreased. The law’s existence remains a crucial part of Quebec’s identity, reflecting the province’s commitment to gender equality and individual autonomy.

In the broader context, Quebec’s approach to married names remains a unique case, raising important questions about personal freedom, cultural norms, and the evolving nature of marriage and identity in modern society.

As discussions around these issues continue, it becomes evident that the choice of a name, far from being a mere formality, is deeply rooted in notions of identity, tradition, and personal freedom. Perhaps Quebec’s Civil Code will be changed to allow more women freedom over their names in the future.

WTF Fun Fact 13645 – Electric Eels & Electroporation

Researchers at Nagoya University in Japan have found that electric eels, known for their ability to generate powerful electric shocks, can influence the genetic makeup of nearby organisms. This study sheds new light on the process of electroporation – a technique typically associated with laboratory settings.

Electroporation involves using an electric field to create temporary openings in cell membranes. This process allows molecules like DNA or proteins to enter cells. The research team hypothesized that the electric eels’ discharge could naturally induce this process in the environment.

Electric Eels – From Laboratory to Riverbanks

The team’s experiment involved exposing young fish larvae to a DNA solution marked with a glowing indicator. They then introduced an electric eel, which discharged electricity as it bit a feeder. The results were remarkable: about 5% of the larvae showed evidence of successful gene transfer.

“I always believed that electroporation might occur in nature,” says Assistant Professor Iida. “The electric eels in the Amazon could be natural power sources, causing genetic modifications in other organisms through environmental DNA and electric discharge.”

This discovery challenges the conventional understanding of electroporation as solely a man-made process. It opens up exciting possibilities for further exploration of electric fields’ natural impacts on living organisms.

Other studies have noted similar natural phenomena, where environmental electric fields like lightning can affect organisms such as nematodes and soil bacteria. This insight into electric eels’ role in gene transfer adds a new dimension to our understanding of natural genetic processes.

Professor Iida is enthusiastic about the future of this research area. “The natural world holds complexities that our current knowledge may not fully grasp. Discovering new biological phenomena based on unconventional ideas can lead to groundbreaking advancements in science,” he asserts.

Nature’s Electrifying Influence on Genetics

The Nagoya University study not only expands our understanding of electroporation but also highlights nature’s ingenious methods of genetic transfer.

Electric eels now emerge as potential agents of natural gene editing. This research paves the way for a deeper understanding of how electric fields, both man-made and natural, can influence life on Earth.

The findings from Nagoya University provide a striking example of how nature can mirror processes usually confined to controlled laboratory settings. The ability of electric eels to induce genetic changes in their environment opens up new avenues for understanding and potentially harnessing natural processes for scientific and medical breakthroughs.
