WTF Fun Fact 13660 – Blue Light and Sleep

Scientists have made some interesting discoveries about the connection between blue light and sleep.

Artificial lighting, particularly blue light from LED devices, has a notable impact on us. It disrupts melatonin production, the hormone responsible for regulating sleep, leading to potential sleep issues. But not all blue light is equal.

Blue Light and Sleep

LED lights in our gadgets and homes emit blue light, which ranges in wavelength from 380 to 500 nanometers (nm). However, not all blue light has the same effect. Wavelengths between 460 and 500 nm are particularly disruptive to melatonin production, impacting our ability to fall asleep.

In response to these challenges, researchers have developed innovative “human-centric” LEDs. These lights are designed to support natural circadian rhythms regardless of the time of day they are used.

The researchers created two types of LEDs, each emitting different wavelengths of blue light. One is tailored for daytime use, emitting blue light close to 475 nm, while the other, intended for evening use, emits blue light near 450 nm. This latter wavelength is outside the range known to disturb sleep.

Testing the New LEDs

The research team integrated these LEDs into conventional light bulbs, converting some blue light into red and green with phosphors, to produce white light. They then conducted an experiment in a windowless room, furnished with a desk, treadmill, and bed, equipped with these innovative bulbs.

Over a three-day period, male volunteers stayed in the room, exposed to different lighting conditions controlled by a computer. This setup allowed for a direct comparison between conventional and new LED bulbs.

Saliva samples collected from 22 volunteers revealed significant differences in melatonin levels based on the type of LED exposure. The use of the new LEDs resulted in a 12.2% increase in nighttime melatonin levels and a 21.9% decrease in daytime melatonin compared to exposure to conventional LEDs.

This suggests that the innovative LEDs could promote alertness during the day and enhance relaxation and sleep quality at night.

Towards a Brighter Future with Blue Light

This groundbreaking research has the potential to revolutionize the way we use artificial lighting. By aligning our indoor lighting with our natural circadian rhythms, we could improve overall well-being, work efficiency, and sleep quality. The hope is that manufacturers of LED lamps and electronic displays will implement these findings, creating environments that nurture our natural sleep-wake cycles. As we continue to spend significant time indoors, these advancements in lighting technology could be key to maintaining our health and productivity in the digital age.

WTF Fun Fact 13659 – Hawaii Snow

While New York City and Boston are typically associated with snowy winters, Hawaii snow has surprisingly outpaced them in snowfall this winter.

Hawaii Snow

The Mauna Kea Weather Center on Hawaii Island experienced a significant snowstorm in late November. That resulted in approximately half a foot of snow. This event occurred on the peaks of the Mauna Kea and Mauna Loa volcanoes.

In contrast, Boston reported only a fraction of its average snowfall, receiving a mere 0.2 inches on December 6. New York City, often pictured with winter snowscapes, has yet to see its first snowfall of the season.

Social media buzzed with images of Hawaii’s snow-covered volcanic peaks. This surprised many who associate the Aloha State solely with sun and surf. However, snow on Hawaii’s higher altitudes is not as rare as one might think.

Hawaii’s High-Altitude Snow

Hawaii’s volcanic peaks, particularly the nearly 14,000-foot-tall Mauna Kea volcano, are known for their altitude and even receive snow occasionally in the summer. Mauna Kea is recognized as the world’s tallest mountain when measured from base to peak, extending about 20,000 feet below sea level. This significant elevation means that these mountains can experience winter conditions distinct from the tropical climate below.

Skiers sometimes venture to these Hawaiian peaks for a unique skiing experience, despite the absence of traditional ski resorts in the state. Blizzard warnings are not unheard of in these areas during the winter months.

On the East Coast, cities like Boston and New York City are experiencing an unusually mild winter. Boston’s most significant snow event in January produced only 3.5 inches, while New York City’s largest was a modest 1.8 inches in February. Tom Kines, a senior meteorologist at AccuWeather, highlighted that this level of snowfall is atypical for these cities. Boston’s average snowfall for November is 0.7 inches, escalating to 9 inches in December. New York City usually sees about half an inch in November and close to 5 inches in December.

El Niño’s Potential Impact

The weather pattern known as El Niño, characterized by warmer ocean waters in the Pacific, might change the East Coast’s winter outlook. Following the end of La Niña in March, El Niño began this summer.

The National Oceanic and Atmospheric Administration (NOAA) has predicted that El Niño could lead to near-normal or slightly above-normal precipitation for the East Coast.

This means there’s still a chance for cities like New York and Boston to catch up and experience their share of winter wonderland scenes. El Niño’s influence could bring more wet weather to these areas, potentially increasing their snowfall totals as the winter progresses.

WTF Fun Fact 13655 – Ice Age Fire Art

Surviving the Ice Age required more than just hunting and gathering – there was fire art. OK, hear us out.

As they gathered around fires for warmth and safety, something more than just physical comfort emerged. This was a time for them to indulge in an artistic pursuit that continues to fascinate us today.

The Paleolithic Animator and Ice Age Fire Art

In recent research published in PLOS ONE, a team led by archaeologist Andy Needham proposed an intriguing idea. They suggested that Ice Age artists used the flickering light of fire to bring their stone carvings to life.

These 15,000-year-old limestone plaquettes, adorned with animal figures, were not just static art. Instead, under the dynamic light of a fire, they appeared to move, animating the etched creatures. Fire art!

Needham’s team studied various limestone plaquettes found at the Montastruc rock shelter in southern France. These carvings, attributed to the Magdalenian culture, showcased a range of animals like horses, ibex, and reindeer.

Interestingly, these plaquettes showed signs of thermal damage, suggesting exposure to fire. But was this intentional?

Experimental Archaeology Sheds Light

To answer this, the researchers turned to experimental archaeology. They created replica plaquettes and subjected them to different fire scenarios. These experiments aimed to replicate the pinkish discoloration seen on the originals. The results? The patterns suggested that the artworks were deliberately placed near the hearth, likely as part of the creative process.

Further exploring this idea, the team used virtual reality to simulate firelight’s effect on the plaquettes. The results were fascinating. The irregular lighting from the fire brought an illusion of movement, making the animals seem like they were alive and moving across the stone surface.

The Role of Pareidolia in Ice Age Fire Art

This phenomenon can be partly explained by pareidolia, where the human brain perceives familiar patterns in random objects. In the flickering firelight, viewers would see incomplete forms on the plaquettes. Their brains would fill in the gaps, creating a dynamic viewing experience.

The Ice Age artists might have used this to their advantage. They could start with natural rock features to shape their animals, allowing the firelight to complete the picture. This interaction between the art, the rock’s natural form, and the dynamic firelight created a captivating experience, unique to the Paleolithic era.

Beyond survival, these artistic endeavors provided a social outlet. After a day of survival tasks, our ancestors likely gathered around the fire, not just for warmth but for a communal experience. Here, they could indulge in storytelling, companionship, and artistic expression.

The act of creating art by firelight was perhaps as important as the art itself. It wasn’t just about the final product but about the process of creation, the gathering of minds, and the sharing of ideas. This communal aspect of Ice Age art adds a deeply human dimension to our understanding of these ancient peoples.

Art as a Cultural Practice

Ice Age art wasn’t merely aesthetic; it was a cultural practice imbued with meaning. The process of drawing, the summoning of spirits, and even acts of destruction (like deliberate breakage or fire damage) could have had significant roles in their society.

These artistic sessions by the firelight might have served multiple purposes – from summoning spirits to strengthening community bonds. The plaquettes, once used, could have been discarded or intentionally destroyed, suggesting a transient nature to this art form.

WTF Fun Fact 13653 – Vomitoriums

The ancient vomitoriums apparently had nothing to do with vomiting at all!

The “vomitorium” has long been associated with images of ancient Romans indulging in excessive feasting only to purge themselves to eat more. However, this widespread belief is a historical misconception. The real meaning of vomitorium in Roman culture was quite different and far less grotesque.

Vomitorium are Exits

In reality, a vomitorium was an architectural feature in ancient Roman amphitheaters and stadiums. The word, derived from the Latin vomitus, which means to spew forth, referred to the large passageways that allowed crowds to exit rapidly into the streets.

These passageways were efficient in dispersing large groups of people from the venues, similar to how food is expelled from the stomach.

The false notion of the vomitorium as a place for purging after excessive eating likely stemmed from a misunderstanding of the Latin language.

It was an easy jump from “vomitorium,” a term describing the spewing of crowds, to a place for vomiting. The misinterpretation was possibly fueled by modern literature and an already existing stereotype of ancient Romans as excessively indulgent.

Literary Exaggerations

Classical texts that described Roman feasts and excesses played a role in cementing this myth. Works like Seneca’s Letters and the satirical ‘Satyricon’ by Petronius depicted scenes of lavish Roman feasts and debauchery. These descriptions, often satirical and exaggerated, influenced modern interpretations and led to the vomitorium myth.

Roman feasts, especially among the upper class, were indeed grand. They involved elaborate dishes and communal eating. Entertainment was common, with dancers and musicians adding to the festivities. Women and men dined together, which was a departure from the Greek tradition.

The feasts could include extravagant presentations, but there is no historical evidence to suggest that these gatherings included rooms specifically designated for purging.

Contrary to the image of constant overindulgence, the diets of both wealthy and poorer Romans were predominantly grain-based. The wealthy had more access to wheat and meats, while the poorer sections of society consumed more millet.

This dietary pattern indicates that while the rich could afford more lavish meals, their eating habits were not as extreme as the myth of the vomitorium would suggest.

Debunking the Myth of Vomitoriums

The vomitorium is a great example of how misconceptions can arise from misinterpretations and satirical representations. It wasn’t a space for bingeing and purging but rather an architectural innovation for crowd management.

WTF Fun Fact 13543 – Final Days of the Pony Express

In the 1860s, the Pony Express emerged as a revolutionary mail service, connecting the East and West coasts of the United States.

This legendary system, although short-lived, played a crucial role in American history, especially during its turbulent Civil War era. Its establishment was a response to the dire need for faster communication across the vast expanse of the country.

Challenges and Downfall

The demise of the Pony Express was a result of several factors, not just the advent of the transcontinental telegraph. Key among these was the deteriorating financial state of its parent company, Russell, Majors, and Waddell. This company had already been financially strained due to various misfortunes, including the loss of a large oxen herd and the impact of the Pyramid Lake War, which led to the destruction of many stations and the loss of essential resources.

The operating costs of the Pony Express were substantial. It needed about $1,000 daily to function, but its income fell short. Despite an initial charge of $5 per ounce for mail (later reduced to $1), the service was too expensive for the general public, limiting its use to newspapers and businesses. The company’s total expenses amounted to $700,000 against receipts of about $500,000.

Internal conflicts within the company and external pressures further aggravated the situation. The arrest of William Russell on charges related to stolen government bonds was a significant blow. Alexander Majors’ preparation for bankruptcy sent shockwaves through the business community, undermining confidence in the company.

Transition and Closure of the Pony Express

Despite these challenges, the Pony Express continued to operate, albeit at a loss. The government attempted to salvage the situation by merging the Pony Express with the Butterfield Overland Mail Company, but the effort was short-lived. The completion of the transcontinental telegraph line in October 1861 made the Pony Express obsolete, leading to its closure two days after the telegraph’s completion.

In its 18 months of operation, the Pony Express completed 308 runs, covering around 616,000 miles. This distance is equivalent to circling the Earth over 30 times. It successfully delivered 34,753 letters, losing only one mail bag throughout its operation. The primary issue, however, remained its financial non-viability.

Historical Significance

Despite its financial failure, the Pony Express is remembered for its significant impact. It was a testament to the courage, determination, and ingenuity of its founders and workers. The service played a vital role in keeping California and the West connected to the rest of the country, especially as the nation was on the brink of war. It filled an urgent need of its time and etched its name in the annals of American history.

The Pony Express’s closure marked the end of an adventurous and bold experiment in American communication history. It paved the way for more sustainable and technologically advanced means of communication, signifying the nation’s progress. Yet, the story of the Pony Express continues to captivate the imagination of many, symbolizing the relentless American spirit.

WTF Fun Fact 13617 – The Stolen Gold Toilet

On a quiet morning in early 2019, Blenheim Palace became the scene of the theft of an 18-karat gold toilet. The piece, named “America,” was crafted by Italian artist Maurizio Cattelan. This functional piece of art was valued at a staggering $6 million. It was not only a statement on wealth but also open for palace visitors to use.

The Plot of the Gold Toilet Heist

Four men—James Sheen, Michael Jones, Fred Doe, and Bora Guccuk—executed the heist at the ancestral home of Winston Churchill. They snatched the golden toilet, leaving behind a trail of destruction and water damage. This act spurred a nationwide manhunt that resulted in their capture and subsequent charges ranging from burglary to conspiracy.

The aftermath of the theft left the palace with substantial flood damage. Of course, the audacity of the crime has both baffled and captivated the public. The men face a court date in late November. But the fate of the toilet remains shrouded in mystery. Authorities speculate that they may have melted down the golden throne, its form forever lost to greed.

“America”

The golden toilet, on display for visitors to use, questioned the art market’s extravagance. It stood as a challenge, blurring the lines between high art and everyday objects. The theft of the piece has stirred a debate about the value we place on art and the lengths some will go to own or destroy it.

“America” was more than a dazzling fixture; it was an interactive installation that invited contemplation on opulence and art’s accessibility. By making such a luxury available to all, the artwork broke down barriers. It allowed the public to partake in what is typically exclusive to the affluent. Cattelan’s work not only nods to the excesses of the art market but also poses questions about the value society places on material wealth.

The art community and the public alike await with bated breath for any news of the lost masterpiece. Will it resurface, or has it been irreversibly lost to the annals of infamous art heists?

This tale of ambition, art, and audacity continues to evolve. It reminds us of the potent allure that art holds and the powerful statements it can make—even when it comes in the form of a gold toilet.

WTF Fun Fact 13616 – Belly Flop Science

In a splash of scientific curiosity, researchers from Brown University have dived into the mechanics of the belly flop. They’ve emerged with insights that could ripple through the field of marine engineering. Their research didn’t just skim the surface. The air-to-water impact dynamics resonate beyond the poolside into naval design and safety.

The Sting of Impact: A Fluid Problem

Assistant Professor Daniel Harris explained the painful truth behind the belly flop’s notorious smack. The sudden halt of a body moving from air to still water creates a formidable reaction force. This results in the body’s shockingly painful reception. This resistance, familiar to any brave soul attempting a belly flop, also poses serious considerations for naval engineering, where structures frequently endure similar high-impact forces.

The research team conducted experiments that replicated the belly flop using a blunt cylinder that vibrated upon impact. Previous studies have often focused on rigid bodies hitting the water. But Harris’s team explored the effects when the object is flexible, allowing for shape change or deformation under force.

Springing into Safer Belly Flop Landings

The researchers attached a soft “nose” to their impactor, buffered by a system of springs designed to soften the blow. It works much like a car’s suspension system. The assumption was that a more flexible system would distribute the impact over a longer period. This would reduce the maximum force felt during the splashdown.

However, their findings defied expectations. Instead of consistently cushioning the blow, the flexible system sometimes intensified the impact force. The culprit? The springs themselves. If not perfectly tuned, the springs’ softness could lead to increased vibrations, adding to the slamming force rather than mitigating it.

The key to a less painful impact lies in the delicate balance of the springs’ stiffness and the height from which the object is dropped. The springs must be just soft enough to absorb the impact gently without causing additional rapid oscillations.

The experiments, while causing a few wet lab coats, have paved the way for innovative approaches to entering water smoothly. Taking cues from nature, the researchers are now exploring how diving birds maneuver to lessen the blow of water entry. Their aim is to design a robotic impactor that mimics these biological techniques for blunt objects.

Implications Beyond the Belly Flop

This study, supported by the Office of Naval Research and Naval Undersea Warfare Center, has far-reaching implications. By understanding the vibrational interplay between structure flexibility and impact forces, engineers can develop safer, more resilient marine vessels and structures. They’ve effectively turned the dreaded belly flop into a lesson in sophisticated design and safety.

The research not only offers a recipe for less painful pool antics but equips marine engineers with the knowledge to better navigate air-to-water transitions.
