WTF Fun Fact 13558 – Mental Imagery

Teenagers are often vulnerable to spirals of negative thoughts, but new research suggests a possible solution: mental imagery.

The Study on Mental Imagery for Teens

Oregon State’s Hannah Lawrence, an assistant professor of psychology, spearheaded the study. The results indicated that shifting focus to mental imagery acts is a strong distractor. In fact, it’s more of a distraction than simple verbal thoughts for adolescents trapped in negative ruminations.

Lawrence’s insights shine a light on a significant issue. Drowning in past regrets not only deepens one’s sorrow but also makes emotional regulation a greater challenge.

Introducing brief diversions, especially in the form of mental imagery, offers a momentary break from these cyclic patterns. This could potentially facilitate a bridge to more extensive help through therapy, familial support, or friendships.

Experiment Procedure

Published in the Journal of Affective Disorders, the research aimed to contrast the impact of verbal thoughts and imagery-based thoughts on the general mood of adolescent participants.

The study encompassed 145 participants, aged 13 to 17, predominantly white, with 62% females. These individuals were from a rural New England area. A striking 39% displayed symptoms consistent with clinical depression.

The mood-setting phase involved an online game, inducing feelings of exclusion among the participants. Subsequently, they were divided into groups, engaging in either rumination or distraction exercises using either verbal or imagery-based prompts.

For rumination, a prompt might be “Imagine the kind of person you think you should be.” For distraction, it could be as mundane as “Think about your grocery list.”

Key Findings on the Power of Mental Imagery

The research found that both forms of rumination (verbal and imagery) affected the participants’ moods similarly. However, mental imagery stood out as a more potent form of distraction.

Lawrence noted, “Using mental imagery seems to help us improve our affect, as well as regulate our nervous system.” The form of negative thoughts, be it verbal or visual, may not matter as much as the relentless focus on distressing matters.

The potency of mental imagery is still not entirely understood. It may be the case that imagery demands more effort and is more immersive. Therefore, it elicits stronger emotional responses, thus serving as a better distraction.

There’s also evidence suggesting that visualizing mental images activates the same brain regions as witnessing those events firsthand.

The Evolution of Rumination

Lawrence has observed that while some adults stick to one form of rumination, most teenagers report employing both verbal thoughts and mental imagery. These patterns might solidify over time, becoming habitual and reinforcing the negative imagery or messages.

Lawrence highlights the crucial nature of her work with teenagers, expressing her hope that early interventions can help these youngsters navigate to adulthood without being tethered to detrimental thought patterns.

WTF Fun Fact 13556 – New Indo-European Language

Archaeologists may have discovered a new Indo-European language related to Hittite.

In the heart of north-central Turkey lies Boğazköy-Hattusha. This UNESCO World Heritage Site is a testament to the advanced urban architecture and artistry of the bygone Hittite Empire. These remnants of history not only provide a glimpse into an ancient civilization but its linguistic gems.

A Surprising Discovery

The Late Bronze Age, spanning from 1650 to 1200 BCE, saw the rise of the Hittite Empire as a dominant force in Anatolia. Beyond their prowess in warfare, the Hittites had a keen inclination towards documentation. From chronicling their monumental battles to codifying laws, they left no stone unturned. The medium? Clay tablets.

To date, researchers have discovered over 30,000 of these in Boğazköy-Hattusha, with most inscribed in the Hittite language.

A New Indo-European Language Related to Hittite

Among the vast array of Hittite tablets, researchers stumbled upon an anomaly: tablets inscribed in an unknown language.

Preliminary investigations suggest this language belonged to the people of Kalašma, near the north-western fringe of the Hittite heartland. The language’s nuances hint at similarities with Luwian, another tongue from the Hittite era.

Initial studies of the tablets indicate that they might detail ancient cultic rituals specific to Kalašma. Professor Daniel Schwemer from Julius-Maximilians-Universität Würzburg emphasizes the Hittites’ unique interest in foreign languages, especially when associated with rituals.

The mystery language, while distinct, showcases clear ties to the Indo-European family of languages.

This linguistic family spans across vast territories, enveloping languages like Hindi, Persian, Russian, and English. In Europe, apart from the unique Basque spoken in the Basque Country, most languages trace their origins back to the Indo-European lineage.

Ongoing Investigations

While the discovery of this new language has piqued the interest of linguists worldwide, much remains to be understood. Researchers are working tirelessly to decode the Kalasmaic text, which remains largely elusive.

The excavation in Boğazköy-Hattusha, spearheaded by the German Archaeological Institute, has garnered support from various organizations including the Thyssen Foundation, the GRH Foundation, the Volkswagen Foundation, and the Italian Ministry of Foreign Affairs. This collaborative effort brings together experts from different universities to interpret the vast wealth of information these tablets offer.

WTF Fun Fact 13554 – The Most Dangerous Jobs

When we think of the most dangerous jobs, our minds often drift to high-action roles, like police officers or firefighters. However, statistical data paints a different, more nuanced picture.

It’s not uncommon to hear discussions about the perils of patrolling the streets. However, data from the U.S. Bureau of Labor Statistics (BLS) sheds light on the occupations that statistically face higher risks daily, and they might not be the ones you’re thinking of.

The Real Most Dangerous Jobs in America

Various blue-collar roles often go unnoticed in their level of peril.

For example, mechanics – both supervisors and those specializing in heavy vehicles – face significant challenges in their workplaces. Heavy vehicle mechanics, dealing with substantial machinery like bulldozers and tractors, confront transportation incidents frequently, with many hazards stemming from the machines they’re entrusted to service.

It’s not just the machinery-oriented jobs that bear these dangers. Those who maintain our public and private spaces, grounds maintenance workers, also navigate risks. Their tasks might appear benign – manicuring lawns, trimming trees, and tending to parks – but their fatal injury rate is on par with heavy vehicle mechanics. Surprisingly, transportation incidents are their predominant threat.

Moreover, general maintenance workers and construction laborers experience considerable hazards. Accidental contact with objects, equipment malfunctions, and falls from significant heights are everyday threats they navigate, often without the same public acknowledgment of their risks.

Perspective on Peril

When juxtaposed with police officers’ fatal injury rate of 14 per 100,000 workers, it becomes evident that several other occupations face equal or even greater threats. The BLS data brings forth an intriguing perspective: while the dangers of law enforcement are well-publicized and recognized, many other workers face similar or heightened risks in relative obscurity.

So the real most dangerous jobs?

  • Logging workers
  • Airline pilot and flight engineers
  • Derrick operators in oil and gas
  • Roofers
  • Garbage collectors
  • Iron workers
  • Delivery drivers
  • Farmers

Even crossing guards rank higher on the deadly jobs list than police officers, which come in at #22. And it’s not that having the 22nd most dangerous job isn’t dangerous – it certainly is. The issue is we don’t often appreciate the extent to which the people who collect our trash or deliver our packages also put their lives on the line every day when they head to work.

Behind the Numbers

The BLS’s Census of Fatal Occupational Injuries is a treasure trove for understanding the nuances of workplace fatalities. This analysis spotlighted 263 professions, each boasting a workforce of at least 50,000 individuals.

To determine the fatal injury rate, fatalities were compared to the number of roles in that occupation. The average from 2014-2018 was then calculated to minimize the influence of yearly variations.

Information regarding the predominant causes of fatal accidents was extracted from this comprehensive census. Simultaneously, salary insights came from the Occupational Employment Statistics Survey.

Recognizing the latent dangers in these professions accentuates the importance of proper safety training and practices. It’s important to acknowledge the sacrifices and challenges faced by these unsung heroes in our everyday lives.

So, the next time you see a mechanic working under a vehicle, a roofer working on a house, or your local trash collector, take a moment to appreciate their dedication and the risks they take daily.

WTF Fun Fact 13552 – Blue Whale’s Heartbeat

A blue whale’s heartbeat can be detected from an astonishing distance of two miles away!

The Mighty Pulse of the Blue Whale

The blue whale, known as Balaenoptera musculus, reigns as the largest creature on our planet. Its size surpasses even the mightiest dinosaurs. One of its awe-inspiring attributes? Under the right conditions, you can detect a blue whale’s heartbeat from an incredible distance of two miles away.

The Heart: Size and Scale

First, consider the immense size of the blue whale’s heart. It weighs around 400 pounds (181 kilograms) and is about as large as a small car. This massive organ pumps blood through a creature that can be up to 100 feet long and weigh as much as 200 tons. Each beat sends gallons of blood throughout its enormous body, delivering oxygen to muscles and vital organs.

Mechanics of Each Beat

The rate of the blue whale’s heartbeat also intrigues researchers. When a blue whale surfaces, its heart beats eight to ten times per minute. Yet, during a deep dive, this rate can plummet to a mere two beats per minute. This drop in heartbeat allows the whale to conserve oxygen and stay underwater for durations that can reach 90 minutes.

Each heartbeat exerts tremendous force. As the heart contracts, it generates strong pressure waves. Given the power and size behind each beat, these waves can travel for miles.

Tools of Detection: Hydrophones

Researchers use hydrophones, underwater microphones, to tap into the ocean’s soundscape. These devices pick up a range of sounds, from the melodies of humpback whales to the conversations of dolphins and the distant rumblings of underwater earthquakes. Amid these myriad sounds, the rhythmic thud of the blue whale’s heartbeat offers valuable information.

Water conditions, including temperature, salinity, and depth, affect how sound travels underwater. However, the unique rhythm of the blue whale’s heartbeat stands out, even in this busy sonic environment.

Heartbeat and Conservation

Studying the blue whale’s heartbeat has implications for conservation. Tracking the heart rate can give insights into the health of the species. Human activities, such as shipping or underwater drilling, can stress whales and alter their heart rates. By listening to the ocean’s pulse, scientists can determine the effects of human-caused noise on these marine giants and adjust conservation strategies accordingly.

Additionally, by understanding the blue whale’s heart, we can explore the limits of size in the animal kingdom. This knowledge might explain the maximum potential size of living organisms and provide insights into the evolution of marine giants.

WTF Fun Fact 13545 – Stanford Taylor Swift Course

A Stanford Taylor Swift Course is on the books at Stanford. The aim? To explore the storytelling prowess of Taylor Swift, an artist who has, over a decade, deftly blended musicality with intricate narratives.

A Literary Dive: The Stanford Taylor Swift Course

Every week, students in this course will deep dive into one of Swift’s 10 albums. They’ll not just listen but dissect, focusing keenly on lyricism, storytelling, and oblique literary references.

Ava Jeffs, a sophomore at Stanford, championed this course offering. Her vision? “Situate it in the English department,” she emphasized to SFGATE. Jeffs believes in drawing parallels between Swift’s lyrical content and classic literature. For her, this course is a journey, one that maps the intricate lanes of literature onto the vast avenues of Swift’s music.

Swift’s musical repertoire often nods to literary giants. A striking example is the track “Ivy,” which echoes a phrase from Miller Williams’ poem “Compassion.” Even the album title, “Evermore,” has fans drawing connections to an Emily Dickinson poem.

These literary tie-ins signify the depth and breadth of Swift’s artistic canvas, and this course intends to highlight and celebrate these connections.

The Making of the Course

This new course is part of Stanford’s Student-Initiated Courses, a unique initiative where students pitch activity courses on a credit/no credit basis. Every SIC requires the backing of a faculty member, and for Jeffs, that support comes from Mark McGurl.

While Swift released her debut album in 2006, Jeffs’ admiration for the singer spans almost her entire life, creating a personal resonance and passion for this academic endeavor.

While Stanford’s course might sound avant-garde, it isn’t the first academic foray into Swift’s art.

In 2022, both New York University and the University of Texas at Austin explored Swift’s artistry in their courses. Stanford, however, aims to go a step further. Jeffs sees her course as a challenge to higher education norms, urging institutions to place popular music on the same pedestal as classical literary works.

For Jeffs, Swift’s narrative style holds immense academic value. She believes that Swift’s focus on storytelling mirrors the intricacies found in classic literature.

WTF Fun Fact 13539 – Male Menstruation in Egypt

While male menstruation sounds like an anomaly, accounts from Egypt painted a curious picture.

During the Napoleonic campaigns in the early 19th century, French soldiers noted a peculiar condition among the local Egyptian men: many reported blood in their urine, leading to the label “the land of the menstruating men.”

Deciphering Male Menstruation

The actual cause behind this perplexing phenomenon is a parasitic disease named schistosomiasis. It originates from Schistosoma worms.

When freshwater snails infected with these parasites release larvae, those larvae can penetrate the skin of humans who come into contact with the water.

Once the larvae invade a human host, they mature into adult worms that live in the blood vessels. The female worms lay eggs, some of which the body excretes through urine or feces, and some remain in the body.

It’s these eggs that can cause inflammation, tissue damage, and bleeding when they lodge in the bladder or intestine.

The presence of blood in urine, or hematuria, became a characteristic symptom among many Egyptian men. This sign of schistosomiasis was the source of the “male menstruation” confusion.

The disease not only caused physical distress but also carried a significant cultural and psychological burden given the societal perceptions of the symptoms.

French Soldiers and Schistosomiasis

In the late 18th century, under the leadership of Napoleon Bonaparte, French ambitions extended beyond Europe, aiming to challenge the British Empire’s growing dominance.

The French campaign in Egypt, which began in 1798, was a strategic endeavor to disrupt British trade routes to India and spread revolutionary ideals. Napoleon, with an army of approximately 35,000 soldiers, invaded Egypt, capturing Alexandria and later Cairo.

This expedition was not purely military; it also included scholars and scientists who studied the ancient and contemporary culture of Egypt. Their presence led to significant discoveries, including the famed Rosetta Stone.

However, while the campaign had initial successes, it faced challenges, such as an encounter with schistosomiasis.

While the local Egyptians bore the “menstruating men” moniker, the French soldiers were not immune. Many who waded in the Nile for bathing or other activities also contracted the disease. However, the term likely stuck more with the Egyptians due to pre-existing observations.

Unraveling the Mystery of Menstruating Men

It took some time before medical professionals connected the dots. The visible blood in urine, a clear symptom of a severe schistosomiasis infection, was initially misunderstood. (However, both men and women suffered from this symptom.)

Eventually, with advancements in medical knowledge and further studies in parasitology, the real nature of the disease became apparent. Scientists and doctors recognized that the “male menstruation” was actually a manifestation of schistosomiasis.

Modern medicine offers effective treatments for schistosomiasis, primarily using the drug praziquantel. Efforts to control the disease also focus on reducing the population of infected snails and improving sanitation to prevent contamination of freshwater sources. Education campaigns aim to reduce human contact with infested water.

Today, the disease remains endemic in many parts of Africa, including Egypt, but global health initiatives strive to reduce its impact.

Recognizing the history and myths surrounding schistosomiasis can help in understanding its cultural implications and the importance of continued efforts to combat it.

WTF Fun Fact 13538 – The Power of Smelling Coffee

Do you perk up in the morning after smelling coffee? Maybe you start to feel it working even before you’ve had a sip. Or perhaps you do some of your best work at the coffee shop when you can smell those invigorating beans all day.

Well, that makes sense!

Coffee’s Olfactory Power

Many of us start our day with the intoxicating aroma of coffee. But there’s more to this scent than just an olfactory delight. In 2008, a group of researchers led by scientist Han-Seok Seo looked into the science behind this phenomenon. Their findings reveal that coffee’s aroma doesn’t just wake up the senses but might also rejuvenate the brain.

Smelling Coffee vs. Sleep Deprivation and Stress

Lack of sleep stresses the body and mind. Sleep-deprived individuals often grapple with cognitive and physical health challenges.

Given these effects, Seo’s team wondered if coffee’s aroma could counteract the negative impacts of sleep deprivation. Their subject of choice for this exploration? Laboratory rats.

The team exposed both well-rested and sleep-deprived rats to the scent of coffee. They then examined gene and protein expressions in the brains of these rats. The results were astonishing.

Rats exposed to the coffee aroma showed varied activity in 17 genes. Out of these, 13 exhibited different mRNA expressions when comparing the sleep-deprived group to the group that inhaled coffee while sleep-deprived.

Translating Science: What it Means for Us

In simple terms, inhaling coffee aroma seemed to recalibrate the brain’s workings. It potentially offsets the harmful impacts of sleep deprivation.

Among the impacted genes, some are linked to proteins with antioxidant properties. These antioxidants help protect nerve cells from stress-induced damage.

So, the smell of coffee might do more than just perk us up; it could protect our brain cells from stress-related harm.

The Power of Smelling Coffee Goes Beyond Coffee

Seo’s groundbreaking findings pave the way for more questions. If the aroma of coffee yields such benefits, what about other scents? Could the whiff of freshly baked bread or the scent of rain bring their own set of health benefits?

Next time the weight of sleeplessness bears down on you, remember the power of scent. As you pass a café or brew your morning cup, take a moment to inhale deeply. Behind that sense of alertness and the smile that follows lies a fascinating dance of molecules and biology.

WTF Fun Fact 13537 – Black Hole Eating A Star

There’s a black hole eating a star out there at an astonishing rate.

University of Leicester astronomers discovered a star, similar to our Sun, that a relatively small black hole is devouring. Every close orbit results in the star losing a mass equivalent to three Earths!

Watching a Black Hole Eating a Star

The research, chronicled in Nature Astronomy, could be the “missing link” in understanding how black holes disrupt the stars that orbit them. Funded by the UK Space Agency and the UK Science and Technology Facilities Council, this discovery is instrumental in propelling our grasp of celestial phenomena.

An intense X-ray flash originating from the center of galaxy 2MASX J02301709+2836050 is what initially captured the team’s attention. That galaxy is approximately 500 million light-years from the Milky Way.

The anomaly has been designated as Swift J0230. And it was detected in real-time thanks to a pioneering tool designed for the Neil Gehrels Swift Observatory.

Further investigations revealed a curious pattern: Swift J0230 would radiate intensely for about a week, then go dark, resuming its cycle roughly every 25 days.

How a Black Holes “Eats” Star

This behavior parallels certain phenomena involving stars having materials torn by black holes due to close orbits. However, the Swift J0230’s emission pattern positioned it as a bridge between two known categories of these eruptions.

Drawing from existing models, researchers concluded that Swift J0230 demonstrates a Sun-sized star, trapped in an elliptical orbit around a black hole with low mass, situated at the core of its galaxy.

As this star nears the black hole, a gravitational tug wrests away material equivalent to three Earth masses. This process superheats the material to about 2 million degrees Celsius, triggering the massive X-ray emissions detected by the Swift satellite.

Unprecedented Research

Dr. Phil Evans, the lead author, remarked on the unprecedented nature of this find: a Sun-like star being intermittently torn apart by a relatively small black hole. Labeling the phenomenon as “repeated, partial tidal disruption,” Dr. Evans highlighted that such events had been rare finds until now, falling into one of two categories based on their frequency. This new discovery bridges the gap, providing a more comprehensive understanding.

Dr. Rob Eyles-Ferris, who contributed to the Swift satellite study, emphasized the singularity of Swift J0230. Unlike most observed systems where stars are entirely destroyed, this system offers insights into a middle ground. The finding unifies the two previously identified categories of partially disrupted stars.

Further, Dr. Kim Page, part of the study’s data analysis team, is confident that many more similar objects await discovery.

In terms of mass, the team estimates that the black hole is between 10,000 to 100,000 times that of our Sun. That’s a mere fraction when compared to supermassive black holes typically anchoring galaxies. For perspective, our galaxy’s central black hole weighs in at 4 million solar masses.

The Tool That Helped Detect the Black Hole Eating a Star

The University of Leicester team conceptualized and designed a novel transient detector for the Swift satellite, facilitating this breakthrough. This tool instantly detects astronomical X-ray transients—rare and extreme X-ray bursts in previously silent sky regions.

Dr. Caroline Harper, the Head of Space Science at the UK Space Agency, praised the globally-acclaimed Swift mission, shedding light on a minuscule black hole periodically “snacking” on a Sun-like star. The mission’s continued partnership with NASA promises further invaluable cosmic insights.

WTF Fun Fact 13535 – Vampire Bats French Kiss

Did you know that vampire bats French kiss? Don’t worry – it gets weirder from there. They kiss with mouthfuls of blood.

Bats “kissing” with mouthfuls of blood may seem strange. Yet, it tells a story of survival and deep bonds. It’s nature’s way of ensuring that in a world full of challenges, no bat is left behind. Through their blood-sharing rituals, vampire bats teach us about trust, cooperation, and the essence of life. Who knew?

The Vampire Bat

Bats rule the night skies and stand out as the only flying mammals. Their unique abilities, like echolocation, have always intrigued scientists. But among their many attributes, one behavior stands out as both peculiar and endearing. It’s their method of sharing food. In the case of the vampire bat, it means regurgitating blood.

Of the 1,300 bat species worldwide, only three have a taste for blood. These vampire bats hail from the Americas. Unlike the myths that surround them, these creatures have evolved to consume the blood of either birds or mammals, not humans.

For a vampire bat, finding a meal involves skill. They hunt using a combination of heat sensors and a keen sense of smell.

Once they locate their prey, they make a precise cut to access the blood, ensuring minimal harm to the host. Their saliva contains unique enzymes that prevent the blood from clotting, allowing them to feed efficiently.

Vampire Bats French Kiss for Solidarity

Vampire bats exist in a system of reciprocity. They thrive in closely bonded colonies where sharing is not just caring; it’s a matter of life and death.

A bat that goes two days without a blood meal is at risk of starvation. However, in these communities, a bat that has fed for the night will often regurgitate and share its meal with a less fortunate mate.

This isn’t random charity. Bats remember past favors and are more likely to share with bats that have previously shared with them. Among mates, this sharing ritual cements their bond, a sign of trust and affection.

The Role of Hormones

Oxytocin, commonly known as the “love hormone,” plays a part in this sharing ritual. In many mammals, oxytocin fosters a bond between mothers and their young. In vampire bats, elevated oxytocin levels coincide with their blood-sharing behavior. It strengthens the sense of trust and community among bats in a colony.

The act of vampire bats “kissing” with blood might unsettle some. But there’s a profound message embedded in this behavior. In the harsh realities of nature, where survival is a daily challenge, vampire bats prioritize community. They understand the significance of trust and cooperation. Through their unique rituals, they highlight the importance of unity, reminding us that in the face of adversity, no one should be left behind.

It’s easy to misunderstand or fear vampire bats. They’re often painted as malevolent creatures in legends and folklore. The reality is quite different. While they do consume blood, vampire bats are integral to their ecosystems. They’re not villains but rather creatures of survival, teamwork, and kinship.
