WTF Fun Fact 13536 – Digitizing Smell

by

In order to smell, our brains and noses have to work together, so the idea of digitizing smell seems pretty “out there.”

However, if you think about it, our noses are sensing molecules. Those molecules can be identified by a computer, and the smells the humans associated with them can be cataloged. It’s not quite teaching a computer to smell on its own, but maybe it’s best we don’t give them too many human abilities.

The Enigma of Olfaction

While we’ve successfully translated light into sight and sound into hearing, decoding the intricate world of smell remains a challenge.

Olfaction, compared to our other senses, is mysterious, diverse, and deeply rooted in both emotion and memory. Knowing this, can we teach machines to interpret this elusive sense?

Digitizing Smell

A collaboration between the Monell Chemical Senses Center and the startup Osmo aimed to bridge the gap between airborne chemicals and our brain’s odor perception. Their objective was not just to understand the science of smell better but to make a machine proficient enough to describe, in human terms, what various chemicals smell like.

Osmo, with roots in Google’s advanced research division, embarked on creating a machine-learning model. The foundation of this model was an industry dataset, which detailed the molecular structures and scent profiles of 5,000 known odorants.

The idea? Feed the model a molecule’s shape and get a descriptive prediction of its smell.

That might sound simple, but the team had to make sure they could ensure the model’s accuracy.

The Litmus Test: Man vs. Machine

To validate the machine’s “sense of smell,” a unique test was devised.

A group of 15 panelists, trained rigorously using specialized odor kits, was tasked with describing 400 unique odors. The model then predicted descriptions for the same set.

Astonishingly, the machine’s predictions often matched or even outperformed individual human assessments, showcasing its unprecedented accuracy.

Machines That Can ‘Smell’ vs. Digitizing Smell

Beyond its core training, the model displayed unexpected capabilities. It accurately predicted odor strength, a feature it wasn’t explicitly trained for, and identified distinct molecules with surprisingly similar scents. This accomplishment suggests we’re inching closer to a world where machines can reliably “smell.”

But for now, that’s overstating it. The team has made a major leap towards digitizing smell. But machines don’t have senses. They can only replicate the kind of information our brains produce when we smell things. Of course, they don’t have any sense of enjoyment (or repulsion) at certain smells.

In any case, the Monell and Osmo collaboration has significantly advanced our journey in understanding and replicating the sense of smell. As we move forward, this research could revolutionize industries from perfumery to food and beyond.

WTF Fun Fact 13534 – The Roundest Object in the World

by

When it comes to spherical perfection, nothing we’ve ever discovered in space beats Kepler-11145123, the roundest object in the world. This distant star is located about 5,000 light-years away from Earth.

What Defines “Round”?

Before diving into Kepler-11145123, it’s essential to understand what we mean by “round.” Most celestial objects take on a somewhat spherical shape due to the gravitational forces pulling matter toward their centers. However, the force of their rotation tends to squash them at the poles and widen them at the equator, causing an oblate spheroid shape. The difference between the equatorial and polar diameters of a celestial body measures its “roundness.”

Kepler-11145123 was initially discovered as part of NASA’s Kepler mission, designed to find exoplanets by observing stars and the tiny dimming caused by planets passing in front of them. While that was Kepler’s primary task, its trove of data fueled other groundbreaking research as well. Researchers from the Max Planck Institute for Solar System Research in Germany used these precise observations to study the star’s oscillations, which provided clues about its internal structure and, fascinatingly, its shape.

A Surprising Level of Perfection

What truly sets Kepler-11145123 apart is the astonishingly small difference between its equatorial and polar diameters. The star’s equatorial diameter exceeds its polar diameter by a mere 3 km, despite having a diameter of 1.5 million km overall. This difference is microscopic on a cosmic scale and represents an unprecedented level of spherical perfection. For context, the disparity between the Earth’s equatorial and polar diameters is about 42 km, a figure that suddenly feels gigantic compared to this distant star.

The Science Behind the Shape

Kepler-11145123’s almost-perfect roundness is intriguing and prompts the question: how did it get so round? One leading hypothesis is that magnetic fields within the star could be redistributing mass, making it more spherical. However, researchers also point out that the star’s slow rotation rate plays a significant role. The slower an object rotates, the less it gets flattened due to centrifugal forces. Kepler-11145123 spins at a much slower rate than our Sun, thus maintaining its almost perfect shape.

Broader Implications of Being the Roundest Object in the World

The discovery of Kepler-11145123’s unique shape has broader implications for our understanding of astrophysics. It forces scientists to reevaluate models of star evolution, as well as the role magnetic fields play in shaping celestial bodies. Furthermore, this finding might have implications for exoplanet studies. A star’s shape can influence the stability of its planetary orbits, which in turn could have consequences for planetary climates and habitability.

Why Should We Care About the Roundest Object in the World?

Apart from the sheer wonder of discovering such a perfectly round object in space, understanding Kepler-11145123 can help scientists refine their models of stellar behavior and evolution. These models are fundamental to our grasp of the universe, from the life cycles of stars to the forces that shape galaxies. The more accurate our models become, the better we can understand a host of other phenomena, including potentially habitable exoplanets.

WTF Fun Fact 13523 – Narwhal Tusks

by

The narwhal is often referred to as the “unicorn of the sea.” The creature has long fascinated scientists and the public alike with its iconic spiraling tusk. However, recent research reveals that these tusks are not just ornamental; they serve as invaluable biological records.

Just like tree rings can tell us about environmental conditions, the growth rings in a narwhal’s tusk can shed light on the animal’s diet and the changes in its environment.

Studying Narwhal Tusks

An international team of scientists conducted a study by examining ten narwhal tusks obtained from Inuit hunters in northwest Greenland. The tusks, which are actually elongated canine teeth found only in males, were cut in half lengthwise to reveal their growth rings. Each ring represented one year in the life of the narwhal. By analyzing these rings, scientists could gain a unique window into the life history of these Arctic mammals.

Scientists discovered that narwhals’ diets have changed in response to the environmental changes in the Arctic. This change is partly due to the shrinking of sea ice.

They measured levels of mercury, as well as stable isotopes of carbon and nitrogen within each ring. Doing so helped them decipher the types of prey the narwhals had consumed in different years. These markers provided a snapshot of the narwhals’ diets and indicated how high their prey sat on the food chain.

The Narwhal Diet

The researchers found that until the 1990s, when the ice cover in the Arctic was still “extensive but varying,” narwhals primarily fed on sea-ice-adjacent prey like halibut and Arctic cod. However, as the ice cover started to decline between 1990 and 2000, narwhals began to consume more open ocean species. These included such species as capelin and polar cod.

These open ocean species sit lower on the food chain. This was reflected in lower mercury levels in the tusk layers for those particular years.

What’s concerning is that even though narwhals’ diets remained relatively consistent after the year 2000, mercury levels in their tusks started to rise significantly. This increase is thought to be linked to increased coal combustion emissions from southeast Asia. This revelation raises concerns about how pollutants from human activities are affecting even the most remote ecosystems on Earth.

Prof. Rune Dietz of Denmark’s Aarhus University pointed out that tusks in museums around the world represent an untapped data bank. An analysis of these could provide critical insights into how narwhals have adapted to changes over different periods and in different regions. This could lay the foundation for assessing how they are likely to cope with ongoing environmental shifts.

What We Can Learn

This study underscores the importance of understanding how climate change and human activities are affecting marine ecosystems. It shows how even seemingly unrelated things—like coal combustion in one part of the world—can have a ripple effect that impacts the diet and health of animals living in a completely different region.

Narwhal tusks serve as natural archives. They can reveal the complex interplay between marine biology, environmental change, and even global industrial activities. And they’re helping researchers stitch together a more complete understanding of the Arctic ecosystem.

WTF Fun Fact 13510 – Stephen Hawking’s Wheelchair

by

Stephen Hawking’s wheelchair was auctioned off for a staggering $387,000 in 2018.

In addition to his groundbreaking contributions to our understanding of the universe, Hawking’s name evokes an image of a man in a wheelchair, speaking through a voice synthesizer—a testament to his fierce determination and willpower in the face of a debilitating motor neuron disease.

Stephen Hawking and His Legacy

Before diving into the story of the iconic wheelchair, it’s essential to grasp the breadth of Hawking’s influence. Born in 1942, he made substantial contributions to cosmology, particularly in black hole dynamics and the nature of the universe.

His best-selling book, A Brief History of Time, made intricate cosmological concepts accessible to the general public, ensuring his place not just within the scientific community but also in popular culture.

Hawking’s motor neuron disease diagnosis at the age of 21 was a life-altering moment. Doctors predicted a short lifespan, but he surpassed all expectations by living till the age of 76.

As the disease progressed, mobility became a challenge, and the wheelchair became an integral part of his life. It wasn’t just a tool for movement; it became synonymous with his identity, symbolizing his resilience and the human spirit’s triumph over adversity.

Auctioning Stephen Hawking’s Wheelchair

In 2018, Christie’s auction house in London announced “On the Shoulders of Giants,” an auction featuring items belonging to several renowned scientists, including Hawking. The most poignant item was undoubtedly Hawking’s wheelchair, a piece of modern history.

The wheelchair, used by Hawking in the late 1980s and early 1990s, garnered significant attention. While it was an older model and not the high-tech version he used later in life, its historical and symbolic value was immense. The mere fact that such a personal item from a living legend was up for grabs drew significant global attention.

Hawking’s decision to auction his wheelchair was rooted in his commitment to giving back to the community. The proceeds from the sale were designated for two charitable causes close to his heart: The Stephen Hawking Foundation, which supports neurological research and promotes science education, and the Motor Neurone Disease Association, dedicated to supporting individuals like Hawking who face the challenges of this condition.

Bidding on History

The auction saw fervent bidding, with the wheelchair eventually selling for approximately $387,000 – a figure far surpassing initial estimates. The winning bid was not just for a mobility device but a piece of history. The buyer, whose identity remained anonymous, now owned a symbol of determination, brilliance, and the indomitable human spirit.

WTF Fun Fact 13508 – Mamenchisaurus sinocanadorum

by

If you know a kid obsessed with dinosaurs, you may have heard of Mamenchisaurus sinocanadorum. If not, you should let that kid know about this creature immediately because it’s pretty cool.

The Discovery and Classification of Mamenchisaurus sinocanadorum

When we think of the most impressive creatures that ever roamed the Earth, our minds often dart to the giants of the Mesozoic Era – the mighty dinosaurs. Among these behemoths, one dinosaur stands out for the astounding length of just one part of its anatomy: its neck.

Meet the Mamenchisaurus sinocanadorum, a species of dinosaur that boasted a neck almost 50 feet long. That’s a neck six times longer than that of today’s tallest land animal, the giraffe!

Mamenchisaurus sinocanadorum belongs to a group of dinosaurs called the sauropods. They are recognized by their long necks, long tails, and massive bodies supported by four thick, pillar-like legs. Although several sauropods had impressively long necks, the Mamenchisaurus goes well beyond the rest!

The species was unearthed in China and was a significant find for paleontologists. These findings provided more information about the diverse world of sauropods and the different evolutionary paths they might have taken.

A Neck to Marvel At

At nearly 50 feet long, the neck of Mamenchisaurus sinocanadorum was a true wonder of nature. To put it into perspective, that’s longer than a school bus and almost as long as a bowling lane! But what evolutionary benefits did such a lengthy neck provide?

Foraging Strategy
With such an extended reach, this dinosaur could access food sources that were out of reach for other herbivores. This reduced the competition for food. It also allowed the creature to graze over a larger area without having to move its massive body frequently.

Cooling Mechanism
Some theories suggest that a long neck could have served as a cooling mechanism. The large surface area could have helped dissipate heat. This may have been vital for such massive creatures that might have struggled to maintain an optimal body temperature.

Display and Mating
In the animal kingdom, impressive physical features often play a role in mating displays. Though speculative, it’s possible that longer necks might have been seen as more attractive or dominant. This would help individuals with longer necks secure a mate.

The Anatomy Behind the Length

The length and weight of such a neck would require robust support and respiratory systems. Vertebrae would have been elongated and possibly hollowed in sections to reduce weight. Air sacs might have been present to aid in breathing, similar to modern birds. The neck’s muscle and tendon structure would also need to be incredibly strong. But it would also have to be flexible to support and maneuver this impressive length.

Comparing Mamenchisaurus sinocanadorum to the Modern Giraffe

Modern-day giraffe necks measure approximately 8 feet in length and pale in comparison to the neck of the Mamenchisaurus sinocanadorum. However, both animals show that evolution can lead to some astounding anatomical features when they provide an advantage.

It’s intriguing to imagine how these two creatures, separated by millions of years, navigated their habitats with such long necks.

WTF Fun Fact 13506 – Human Hair Can Hold Two Elephants

by

When considered collectively (by the head), human hair can hold two elephants! That’s right, it can support the weight of two giant creatures.

Let’s explain.

The Anatomy of a Hair Strand

To truly grasp the astonishing strength of human hair, we must first delve into its structure. Each strand is composed of keratin, a type of protein. This protein is arranged in coiled coils, a configuration that provides both flexibility and strength to the hair.

The innermost layer, known as the medulla, is surrounded by the cortex, which in turn is encased by the outermost layer, the cuticle. Each of these layers contributes to the hair’s overall resilience.

One individual hair strand, despite its tensile strength, is unlikely to impress anyone with its ability to support weight. However, the collective strength of hair is where the true marvel lies.

The average human head has approximately 100,000 to 150,000 hair strands. When working in tandem, these hairs can exhibit strength that belies their delicate appearance.

Why Human Hair Can Hold Two Elephants

So, how do we arrive at the claim that human hair can hold two elephants? Let’s break it down:

  • An average strand of hair can support about 100 grams in weight. This might not seem like much, but when multiplied by the average number of hairs on a human head (let’s take the midpoint of 125,000 strands), we get a total weight of approximately 12.5 tons.
  • An average adult elephant weighs about 6 tons. So, theoretically, the combined strength of the hair on a human head could support two elephants, amounting to 12 tons!

The capacity of hair to support immense weight is just one facet of its remarkable nature. Hair can stretch up to 30% of its original length without breaking when wet. This elasticity is yet another testament to its durability.

But beyond its tensile strength and elasticity, hair also serves as an indicator of our health, reacts to emotional stimuli (like standing on end when we’re frightened), and plays a vital role in regulating body temperature.

WTF Fun Fact 13504 – The Dots on Strawberries

by

What are the dots on strawberries? You might believe they’re seeds, but you’d be wrong.

It’s not just the layperson who’s been fooled. Even certain educational platforms have, over the years, inadvertently misinformed generations into believing that strawberries carry their seeds on the outside. The truth, however, is far more intriguing.

The small dotted entities on strawberries are known as “drupelets.” But these do contain seeds.

Strawberry Drupelets

Now, the concept of a drupelet can be somewhat counter-intuitive. Each of these tiny fruits contains an actual seed. So, when you look at a strawberry, you’re essentially looking at a collective of multiple fruits.

The evolutionary strategy that led strawberries to develop this unique external fruit-bearing method is fascinating.

The external drupelets potentially increase the chances of seed dispersion. The strawberry’s vibrant red coloration acts as a visual cue for animals, signaling ripeness and inviting consumption. When animals eat these fruits, the seeds within the drupelets get dispersed in the environment, ensuring the strawberry plant’s survival and proliferation.

We’ve Been Misled about the Dots on Strawberries

The strawberry, despite its unique botanical makeup, has earned its place in various cultures worldwide. Its iconic appearance and misinterpreted “seeds” have inspired art, literature, and even fashion. This misrepresentation, while innocent, makes one ponder how many other natural elements we might have misread or misunderstood.

Modern commercial strawberry production seldom concerns itself with the seeds inside the drupelets, as they propagate strawberries using runners, ensuring consistent fruit quality. However, understanding the strawberry’s unique structure has implications for genetic research and potential breeding programs.

By diving deep into the genetic makeup of the actual seeds, scientists could unlock new strawberry varieties or even develop strains more resistant to pests and diseases.

Beyond Strawberries

Strawberries aren’t the only fruits that challenge our conventional understanding. The raspberry, similar in its external seed presentation, also relies on drupelets. Pineberries, which are a blend between strawberries and pineapples in taste, carry the same deceptive exterior. It’s a testament to nature’s ability to consistently surprise and challenge our knowledge.

As the true nature of strawberry “seeds” becomes more widely known, it becomes imperative to adjust educational materials. This ensures future generations have accurate information. Such discoveries, though seemingly minute, underscore the importance of continuous learning and the revision of established knowledge bases.

WTF Fun Fact 13503 – Antarctic Feather Star

by

In the dark waters of the Antarctic, an unknown “sea monster” with an astonishing 20 arms recently emerged – the Antarctic feather star. The researchers had this specimen on ice for years after a near-decade-long expedition during which they collected samples. Only in 2023 did they uncover the latest creature from the deep.

The Antarctic Expedition

This journey into the Antarctic waters spanned almost a decade, from 2008 to 2017. Its primary objective was to study elusive or cryptic sea creatures, especially those belonging to the genus Promachocrinus – commonly referred to as Antarctic feather stars.

While Antarctic Feather Stars bear similarities to starfish and sea cucumbers, they possess a distinct otherworldly appearance, notably when swimming. Their movement, combined with their considerable size, sets them apart in the marine world.

These creatures reside in varying depths, from a relatively shallow 65 feet to an astounding 6,500 feet beneath the waves.

Eight unique species were identified during the expeditions, with half being entirely novel to science. Earlier, only Promachocrinus kerguelensis was unmistakably linked to this genus. A combination of DNA analysis and physical morphology studies led to these recent classifications.

The Strawberry Feather Star

Named Promachocrinus fragarius, this particular discovery stands out. Its body, curiously enough, resembles a strawberry and showcases a range of colors from muted purples to rich reds.

Boasting a staggering 20 arms, this “sea monster” is unlike any other in its category.

The vast number of arms, each intricately designed, adds to its otherworldly presence, particularly when the creature is in motion. When swimming, the feather star presents an ethereal dance in the deep sea, making it a sight to behold.

Unlike other invertebrate ocean animals, the Antarctic Strawberry Feather Star stands out both due to its substantial size and its unique appearance, which is reminiscent of the delicate feathers of a bird, but with a marine twist.

Its habitat in the frozen depths of Antarctica makes its discovery particularly fascinating. Antarctica’s waters are among the least explored due to their harsh and inaccessible nature, making every discovery from this region a notable contribution to marine biology.

The Antarctic Strawberry Feather Star offers a glimpse into the rich biodiversity of our oceans, reminding us of the endless mysteries that lie beneath the waves, waiting to be discovered.

WTF Fun Fact 13498 – Record High Temperature

by

Both Alaska and Hawaii share the same record high temperature of 100°F (37.8°C). It’s quite the surprise for many since Hawaii is a tropical paradise, while Alaska is often associated with icy landscapes and freezing temperatures. Let’s dive into this.

Setting the Stage for a Record-High Temperature

Alaska: Often termed “The Last Frontier,” Alaska is known for its vast wilderness, glacial landscapes, and cold climate. Its Arctic and subarctic climates lead to long, harsh winters and brief summers. However, Alaska isn’t just a frozen wasteland. It has a variety of microclimates, and during its short summer, some regions can get quite warm.

Hawaii: The Aloha State is synonymous with tropical paradise, boasting a warm climate year-round. Hawaii’s location in the central Pacific Ocean ensures it has a tropical climate moderated by oceanic influences. This results in balmy, warm temperatures throughout the year but rarely sees extremes.

The 100-Degree Record-Setting Days

For Alaska, the record was set on June 27, 1915, in Fort Yukon. This town lies just inside the Arctic Circle—a region more associated with sub-zero temperatures than scorching heat. A combination of clear skies, long daylight hours (thanks to its position close to the Arctic Circle), and specific atmospheric conditions allowed for this record-setting temperature.

Hawaii, on the other hand, saw its record 100°F on April 27, 1931, in Pahala, a small town on the Big Island. This record is especially remarkable considering Hawaii’s consistent climate. The island’s oceanic surroundings and regular trade winds generally keep extreme temperatures at bay.

Why Do Hawaii and Alaska Have the Same Record High Temperature?

The Extremes of Latitude: Alaska’s high temperature record may seem surprising, but it’s important to remember that during the summer months, areas close to the Arctic Circle experience almost continuous daylight. This phenomenon, known as the Midnight Sun, means that the ground and the air can continue warming throughout the day and night.

Oceanic Moderation in Hawaii: The vast Pacific Ocean surrounding the Hawaiian Islands plays a crucial role in keeping the state’s temperatures relatively consistent. Water has a high heat capacity, meaning it can absorb and release heat slowly. As a result, areas close to large bodies of water—like Hawaii—tend to have milder, more stable temperatures. While Hawaii does experience warmth, it’s the consistency rather than the extremes that characterizes its climate.

Microclimates and Atmospheric Anomalies: Both states have diverse topographies and climates within their borders. In Alaska, interior regions, shielded from the marine influences, can see more significant temperature fluctuations. Hawaii has elevation changes, leading to cooler areas atop Mauna Kea and Mauna Loa compared to coastal regions. Specific atmospheric conditions, such as high-pressure systems, can lead to unusually high temperatures, even in areas where they might seem out of place.

The Bigger Picture

While this shared record is an interesting climatic quirk, it also underscores the complexity of our planet’s weather and climate systems. Two states, with seemingly opposite general climates, can have moments of convergence due to a multitude of factors.

Moreover, such records emphasize the importance of understanding local weather patterns and anomalies when considering broader climate trends. Just as one cold day doesn’t negate global warming, a single hot day in Alaska doesn’t define its typical climate. It’s the broader patterns and consistent data over time that give us insight into our changing world.

WTF Fun Fact 13496 – Parachuting Beavers

by

Conservation strategies can take on a wide variety of shapes and forms – sometimes they’re scientific breakthroughs or well-planned reintroduction programs; and other times, they are, well, parachuting beavers.

Yes, you read that right.

During the 1950s, in one of the most peculiar conservation efforts, beavers in Idaho were parachuted from planes to aid in repopulation efforts. Here’s the fascinating story.

The Problem: Beaver Overpopulation

Post World War II, Idaho faced a conundrum. With the growth of human settlements and the rise in agriculture, the state found that some regions had an overpopulation of beavers.

These industrious animals, known for their dam-building abilities, often clashed with human development. Their dams would flood roads and farmland, creating challenges for the human inhabitants of the area.

At the same time, other remote regions of Idaho suffered from a lack of beavers.

Historically, beavers played a pivotal role in these ecosystems, creating wetlands that benefited various forms of wildlife. Without them, these ecosystems began to degrade.

The Solution: Aerial Beaver Relocation

To address this imbalance, the Idaho Department of Fish and Game (IDFG) devised a novel solution. Why not relocate the beavers to the regions where they were needed?

But there was a hitch. Many of these areas were so remote that traditional methods of transportation were unfeasible.

Enter Geronimo, the beaver that would pave the way for a unique conservation strategy. As a test subject, Geronimo took several flights, gently floating down via parachute to ensure the safety of the process. After repeated tests (and presumed beaver approval), the IDFG decided to move forward with their parachuting beaver operation.

Operation Beaver Drop: Parachuting Beavers into Idaho

The process was relatively straightforward, albeit unorthodox. Beavers were trapped in overpopulated areas, placed inside protective boxes, and attached to parachutes. An airplane would then fly over the designated release area, and these furry engineers would descend to their new homes.

Between 1948 and 1950, this project saw the successful relocation of over 70 beavers. The majority of them adapted quickly to their new environments, immediately setting to work building dams and establishing new colonies.

The parachuting beaver strategy, despite its odd nature, was deemed a significant success. The relocated beavers transformed the landscapes, aiding in the creation of wetlands and benefiting countless other species in the process. Birds, fish, and mammals found better habitats thanks to the beaver’s natural dam-building tendencies.

Other states didn’t adopt the parachuting strategy (due in part to the development of better transportation methods and roads). But it showcased the lengths to which conservationists were willing to go to ensure the survival and prosperity of a species.

Revisiting the Tale of Parachuting Beavers

For many years, the tale of Idaho’s parachuting beavers was considered an exaggerated myth of the West. That was until 2015, when a film from the IDFG archives was rediscovered. This film, titled “Fur for the Future,” documented the entire process, turning local legend into verifiable history.

Suddenly, a story that sounded like a tall tale had evidence to back it up, and it captured the imagination of people worldwide.

WTF Fun Fact 13495 – Haunted House Carbon Monoxide Theory

by

The haunted house carbon monoxide theory takes a little bit of the ghoulishness out of Halloween. But it its place is something much scarier. Those ghosts might be a sign that you’re being poisoned!

Now, we’re not talking about the haunted houses that you go to for Halloween fun. We’re talking about people who actually feel and hear and see ghosts that they think are coming from beyond the grave.

What’s the Haunted House Carbon Monoxide Theory?

There’s a saying: “When you hear hoofbeats, think horses, not zebras.” Yet, when it comes to stories of haunted houses, the supernatural often takes precedence over the logical.

Such tales have captivated our imagination for centuries, with eerie apparitions, whispered voices, and otherworldly sensations. But could there be a more down-to-earth explanation for these ghostly experiences?

Enter carbon monoxide.

Carbon monoxide (CO) is a colorless, odorless gas that can cause a wide range of health problems and even death when inhaled in large amounts. It affects the body by preventing oxygen from entering cells and tissues, leading to a condition called hypoxia.

The Unusual Cases of “Hauntings”

There’s been a growing awareness of how carbon monoxide poisoning can cause symptoms eerily similar to those described in paranormal encounters.

Take the example from an American Journal of Ophthalmology report from 1921. A family started seeing apparitions and experiencing a constant sensation of being watched. The children lost interest in play, became ill, and the father even witnessed a mysterious woman in black. The mother, too, had her own harrowing encounters. (This example is cited in IFL Science, cited below).

It wasn’t until the father’s brother suggested a more rational cause that the mystery was solved: carbon monoxide poisoning, originating from a broken furnace.

Writer Carrie Poppy described an unnerving presence in her house, complete with auditory hallucinations and a peculiar pressure on her chest to to NPR (via IFL Science). She felt watched and perceived an ominous “whoosh” sound. To her, this was no mere haunting; she believed a demon occupied her home.

The distress became so overwhelming that she found herself in tears nightly. However, a group of skeptical ghost hunters steered her towards a more plausible explanation: carbon monoxide. And sure enough, a gas leak was identified as the root cause.

Haunted Houses and Carbon Monoxide: A Tale Of Ghosts and Gas Lamps?

There’s an intriguing theory that the Victorian era, known for its plethora of ghost stories and an intense fascination with the supernatural, might have had a carbon monoxide connection.

Toxicologist Albert Donnay suggests that carbon monoxide and other toxins could be responsible for a large number of these hauntings.

The Victorians, with their gas lamps and toxic wallpaper, could have inadvertently been subjecting themselves to low doses of poison, leading to hallucinations and the perception of hauntings.

A Logical Explanation in a Paranormal World

While it’s true that not every ghostly encounter can be chalked up to carbon monoxide — some might be hoaxes, products of sleep paralysis, or even crafty hotel managers attempting to boost business — it’s essential to consider the possibility. Often, the answers we seek lie not in the realm of the otherworldly, but in the tangible world around us.

In essence, if you believe you’ve encountered a spectral presence or feel like something’s not quite right in your home, it might not be a ghostly visitor. Instead, it could be a silent and deadly gas.

So, before calling in the paranormal investigators, IFL Science writer Andrew Felton suggests you ring up a technician to inspect your home’s heating system. Your “haunting” might just be a malfunctioning boiler or furnace.

WTF Fun Fact 13494 – John Wilkins’ 17th-Century Moon Mission

by

The first “moon mission” was dreamed up in the 17th century by a clergyman named John Wilkins.

Though the technologies of his time were rudimentary, Wilkins’ imagination and theories displayed a unique combination of audacity and scientific curiosity.

Early Life and Philosophical Leanings

John Wilkins was born in 1614. He was an Anglican clergyman and a founding member of the Royal Society, a body dedicated to the promotion of natural science. Wilkins was a polymath with interests ranging from theology to mathematics and cryptography. These varied interests equipped him with a unique perspective when it came to observing and understanding the cosmos.

John Wilkins’ Plurality of Worlds

Central to Wilkins’ astronomical ideas was the belief in a “plurality of worlds.” This concept was embraced by several thinkers of the era. It postulated that planets and celestial bodies, including the moon, were worlds much like Earth.

By this logic, the moon wasn’t just a shining orb in the sky. It was a place with landscapes, atmospheres, and perhaps even inhabitants. This revolutionary idea was radical and contrary to the predominant geocentric worldview upheld by many in the church.

In 1640, Wilkins published “A Discourse Concerning a New World and Another Planet.” In it, he explored the feasibility of humans traveling to the moon and other planets. He argued that if the moon were a world similar to Earth, humans should be able to travel there. Given the technological constraints of the 17th century, this was a bold proposition. His methods, in hindsight, were understandably primitive.

John Wilkins and the Flying Chariot

Wilkins believed that a “flying chariot” could take humans to the moon. This vehicle would be propelled by wings attached to it, a bit like the way birds fly. He theorized that the chariot’s wings would require less flapping the further it got from Earth due to the thinning atmosphere.

Additionally, he speculated on the absence of gravity in space. He noted that as one ascended, the pull of Earth’s gravitational force would diminish, making it easier to move around. Though rudimentary, such thoughts were a precursor to our modern understanding of the vacuum of space and microgravity environments.

Of course, not everyone was taken in by Wilkins’ ideas. His contemporaries raised various objections. Some focused on the theological implications. If there were beings on other planets, how did they fit into the Biblical narrative? Others doubted the physical feasibility. How would one breathe? How could wings work in the vacuum of space?

Wilkins tackled these questions head-on. He hypothesized that space wasn’t entirely devoid of air. Instead, the atmosphere thinned out but never completely disappeared, providing just enough air for breathing.

Legacy and the Dawn of Space Exploration

Though Wilkins’ moon mission ideas were not actualized in his lifetime, his speculations played a pivotal role in sparking interest in interplanetary exploration. His works represented a significant shift from purely observational astronomy to a more practical, exploration-driven approach.

Space exploration took another three centuries to become a reality. However, the philosophical and theoretical foundation was set in Wilkins’ era.

His thoughts, radical as they were, underscore the human spirit’s relentless quest for knowledge and exploration.

WTF Fun Fact 13492 – Information Seeking Behavior

by

Normally, when we think of smartphone addiction, we think of video games or social media, but information-seeking behavior, such as constantly scrolling through the news, can be hazardous to your health as well.

In our digital age, many people often hear notifications, see never-ending news feeds, and feel the pull to browse news apps daily. This behavior ties into our brain chemistry. Dopamine, a key neurotransmitter, drives our desire to seek information and rewards.

The Role of Dopamine in Information-Seeking Behavior

People often call dopamine the “feel-good” chemical. But it’s better to think of it as a messenger for reward-seeking, motivation, and pleasure. When we experience something pleasurable, our brain releases dopamine. This makes us want to repeat that action.

In the past, dopamine helped us survive. For instance, when our ancestors found food or water, a dopamine rush would push them to keep searching for these essentials.

Why We Seek Information

As societies evolved, so did our dopamine triggers. Now, our brain doesn’t only release dopamine for physical rewards but also for intangible ones like information. Discovering new information gives our brain a dopamine boost. Historically, this made sense. Early humans needed new knowledge for survival, like learning about potential dangers.

Today, each piece of news or an article can trigger dopamine, making us crave more. It’s like how we yearn for food or other activities that make us feel good.

Smartphones: Dopamine Machines

Smartphones and apps capitalize on our dopamine system. Every swipe or notification can be a dopamine rush. The element of surprise—whether the next swipe reveals a meme, a news update, or a message—boosts our dopamine even more.

This unpredictability mirrors slot machines. You never know when you’ll hit the jackpot, making you play more. Likewise, not knowing what the next notification holds keeps us glued to our screens.

However, too much dopamine has its downsides. Over time, frequent dopamine hits from constant scrolling can dull our response. Like how drug users need more drugs over time, we might need more screen time or new information for the same dopamine kick.

This never-ending search for information can overload us. We might struggle to understand or remember what we read. We can even feel mentally exhausted.

Balancing Out Information Seeking Behavior

Knowing dopamine’s role in our online habits can help us use tech wisely. Here’s how:

  • Set Limits: Designate times for browsing news or social media. This reduces the impulse to always check for news.
  • Take Digital Breaks: Stepping away from screens occasionally can help reset our brain’s dopamine response.
  • Choose Wisely: Don’t just scroll. Engage deeply with a few key topics.
  • Control Notifications: Fewer non-urgent notifications mean fewer urges to check your device.

Our relationship with dopamine and information seeking shines a light on our tech habits. Technology offers us endless information, but understanding the dopamine effect helps us use it wisely. By realizing how our brains work in this digital era, we can enjoy tech without letting it control us.

WTF Fun Fact 13491 – Loneliness Kills

by

We can all think of a long list of stuff that’s bad for our health – but did you know loneliness kills as well?

Loneliness Kills in the Age of Connectivity

The dangers of smoking have been widely acknowledged and documented for years. From lung cancer to heart diseases, the repercussions of this habit are severe. Yet, there’s another rising health concern that many might not associate with physical harm: loneliness. Recent studies are revealing that the health risks of prolonged isolation might be as detrimental as smoking.

Ironically, we live in an era termed the “age of connectivity.” Technology has bridged continents, enabling face-to-face conversations without the need for physical proximity. Yet, as we increasingly immerse ourselves in the digital world, it seems we’re drifting apart in the real one. This paradox is contributing to what experts now call an “epidemic of loneliness.”

Loneliness vs. Being Alone

It’s vital to understand that loneliness and being alone aren’t synonymous. One can feel lonely in a crowded room, while another might cherish solitude without feeling isolated. Loneliness is the subjective feeling of being isolated, regardless of the actual social situation.

Loneliness does not merely affect mental well-being; it has severe physical repercussions. Just like smoking, prolonged feelings of isolation can lead to an array of health complications:

  1. Cardiovascular Issues: Loneliness can increase the risk of heart diseases. A lack of social connection has been found to be a significant factor in heart attacks, strokes, and other cardiovascular events.
  2. Reduced Immune Function: Chronic loneliness might diminish the immune system’s efficiency, making individuals more susceptible to illnesses.
  3. Higher Blood Pressure: There’s a growing body of evidence suggesting that lonely individuals might have higher blood pressure than their more socially-connected counterparts.
  4. Shortened Life Expectancy: Perhaps the most alarming revelation is that loneliness can shorten one’s lifespan. It’s on par with other well-established risk factors like obesity and smoking.

The Role of Dopamine

The human brain operates on rewards. Dopamine, the “feel good” neurotransmitter, plays a crucial role in this. When we engage in social interactions, our brain rewards us with dopamine. This encourages us to seek more interactions, fostering bonds and relationships.

When isolated, our dopamine levels can plummet. This can initiate a vicious cycle where the lack of dopamine makes us less inclined to seek out interactions, further exacerbating feelings of loneliness. The pleasure we derive from screens, though momentarily boosting dopamine, lacks the depth and warmth of genuine human connection, often leaving us feeling emptier.

The Modern Loneliness Epidemic

A report by Cigna, a global health service company, emphasized the modern loneliness epidemic, especially in the United States. The findings suggest that most Americans are classified as lonely. Younger generations seem to be at higher risk, which is surprising given their tech-savviness and online connectivity.

Factors contributing to this epidemic include increased screen time, decreased face-to-face social interactions, and the cultural shift towards individualism. The structure of modern life, where both family units and communities are less tight-knit than in previous generations, further fuels the crisis.

Tips for Combatting Loneliness

It’s not all doom and gloom, though. Recognizing loneliness as a genuine health concern is the first step in addressing it. Here are some strategies to combat this silent epidemic:

  1. Community Engagement: Engage in community activities. Joining clubs, organizations, or even group fitness classes can foster new connections.
  2. Digital Detox: Allocate specific times in the day to disconnect from digital devices. Use this time to engage in hobbies, read, or take nature walks.
  3. Seek Professional Help: Just as one would consult a doctor for a persistent cough, seeking therapy for chronic loneliness is vital.
  4. Volunteer: Volunteering can provide a dual benefit. It can reduce feelings of isolation while giving individuals a sense of purpose.
  5. Pet Companionship: Animals, especially dogs and cats, can offer comfort and reduce feelings of isolation.
  6. Establish a Routine: Having a daily routine can provide structure, reducing feelings of aimlessness, which can compound loneliness.

Loneliness Kills: Don’t Let It Ruin Your Life

In an age where we can reach out to someone thousands of miles away with a click, it’s paradoxical to witness a surge in loneliness. Recognizing and understanding its profound effects on our physical and mental health is crucial. As with all health risks, prevention and early intervention are key. We must prioritize genuine human connections, value our well-being, and remember that our health encompasses not just our bodies, but our minds and souls as well.

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 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 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.
