WTF Fun Fact 13480 – Convinced of a Crime You Didn’t Commit

by

It only takes a few hours for you to be convinced of a crime you didn’t commit. It’s a well-known psychological phenomenon.

This isn’t so much a “fun fact” as one that’s kind of awful if you really think about it. And it certainly has implications for questioning crime suspects (or perpetrating psychological abuse).

The criminal justice system relies heavily on the accuracy of human memory and the credibility of its testimonies. Yet, human memory is highly malleable and susceptible to suggestions and false implants. Some wrongful conviction cases suggest that innocent suspects, when questioned using certain tactics, can be led to believe and confess to committing crimes they never did.

This concept goes beyond our typical understanding of “false confessions.” It underscores the potential of forming vivid, detailed false memories of perpetrating serious crimes.

Can You Really Be Convinced of a Crime You Didn’t Commit?

A 2015 study psychologists published in the journal Psychological Science explains it all. It shows how someone can convince innocent participants they had committed crimes as grave as assault with a weapon in their teenage years. (In the years since, more research has corroborated the possibility.)

Lead psychological scientist Julia Shaw from the University of Bedfordshire, UK led the study. She found that a certain type of questioning can help generate these false memories relatively easily. Her team used a friendly interview environment, introduced a few incorrect details, and applied poor memory-retrieval techniques. (Note – the students in the study volunteered, and an ethics review board assesses research plans).

For the study, the research team first contacted the caregivers of university students. They asked them to fill out questionnaires about specific events the students might have experienced from ages 11 to 14. And they instructed them not to discuss the questions with the student/subject.

The researchers then subjected the students to three 40-minute interviews about two events from their teenage years. One real and one was falsely constructed, but included some true details from their past.

The Surprising Results

The findings were startling. Out of the 30 participants told they had committed a crime as a teenager, 21 (or 71%) developed a false memory of the “crime”! A similar proportion, 76.67%, formed false memories of an emotional event they were told about.

The criminal false events seemed just as believable as the emotional ones. Students gave the same number of details, and reported similar levels of confidence, vividness, and sensory detail for both types of events.

Shaw and co-author Stephen Porter hypothesized that incorporating true details into a supposedly corroborated account probably provided enough familiarity to make the false event plausible.

However, there were slight differences in the memories for false events and true events. For example, participants reported more details and confidence in their descriptions of the true memories.

Implications and Applications

These findings emphasize the fundamental malleability of memory. The implications extend to various fields, notably criminal justice, legal procedures, and even therapeutic settings. They indicate the need for vigilance in situations where memory recollection is key. Clearly, the innocent can be led to generate rich false memories of emotional and criminal events!

The knowledge that innocent individuals can be led to create complex false memories quite easily serves as a cautionary tale. And it’s one that hopefully influences the interview techniques that could induce them.

This research also underscores the need for further investigations into the specific interview tactics that contribute to false memories. Understanding these factors can help improve interviewing procedures, and in turn, the integrity of our legal system.

Memory, a cornerstone of our identity and experiences, can be surprisingly plastic and fallible. By studying and understanding its limitations, we can better protect ourselves from the potential distortions. This is part of ensuring a more reliable justice system, and fostering better practices in situations where the accuracy of memory is critical.

WTF Fun Fact 13479 – Taylor Swift Makes Seattle Rumble

by

During two Taylor Swift performances in Seattle on July 22 and 23, 2023, an unexpected phenomenon occurred. Swift’s fans, through their sheer enthusiasm and collective dance movements, generated seismic activity equivalent to a 2.3 magnitude earthquake.

The discovery, made by seismologist Jackie Caplan-Auerbach, brings new meaning to the power of music and fan engagement.

Taylor Swift vs the “Beast Quake”

The local seismometer detected the activity produced by Swift’s fans, comparing it to the famous 2011 “Beast Quake.” The Beast Quake refers to the seismic activity triggered by ecstatic Seattle Seahawks fans. This occurred after Marshawn Lynch’s touchdown in an NFC wild-card game against the New Orleans Saints.

Swift’s performances didn’t just shake the ground – they also broke records. Swift sold out both nights in Seattle. 72,171 fans attended the Saturday show, surpassing the previous venue record of 70,000 set by U2 in 2011.

Although this incident is extraordinary, it’s not unprecedented. Concerts have sporadically registered seismic activity. Notable instances include a 2011 Foo Fighters concert in New Zealand and a 2022 Garth Brooks concert at Louisiana State University in Baton Rouge. However, seismic magnitudes from these concerts weren’t reported at the time.

The Power of Music

Caplan-Auerbach, a geology professor at Western Washington University, was first alerted to the Swift comparison through a Pacific north-west earthquake group she moderates. Upon scrutinizing seismic data from both concerts and the 2011 NFL event, she noticed striking similarities. “I grabbed the data from both nights of the concert and quickly noticed they were clearly the same pattern of signals,” she told CNN.

Despite the minor difference between the NFL event and the Swifties dancing, Swift’s fans still managed to outdo the Beast Quake. The seismic activity caused by their continuous cheering and dancing was twice as strong as that of the Beast Quake. Caplan-Auerbach shared that the shaking “absolutely doubled” that of the Beast Quake.

While the ground-shaking cheer after the Seahawks touchdown lasted for just a moment, the energy driven into the ground by the dancing and cheering Swift fans (in addition to the music) generated seismic activity for a more extended period.

Swift’s Seattle concerts exemplify how her fans’ passion and engagement can literally shake the ground. As Swift’s Eras Tour continues, who knows what other records – or seismic readings – her dedicated fanbase will break.

WTF Fun Fact 13477 – The Sonoran Desert Toad

by

When it comes to the world of psychedelic fauna, few species are as intriguing as the Sonoran Desert toad. It’s technically known as Incilius alvarius. But licking the toad won’t get you high – instead, it might kill you.

Don’t Lick The Toads

Last fall, a plea from the U.S. National Park Service urged visitors to abstain from licking this particular species. The reason? A potent psychedelic compound excreted through its skin has led to increasing instances of poaching, over-harvesting, and illegal trafficking.

Despite the warnings, the toad’s secretions don’t typically induce psychedelic experiences when ingested directly. In fact, they’re toxic when ingested and could lead to cardiac arrest.

When the secretions are collected, dried, and smoked, however, they may elicit auditory and visual hallucinations. Or they may do nothing except get you in a lot of trouble.

The Sonoran Toad and the “God molecule”

The compound responsible for these effects is called 5-MeO-DMT. It’s also in plants as well as the Colorado River toad. And it’s so potent some people have dubbed it the “God molecule.”

The growing demand for powerful hallucinogenic substances now poses a risk to toad populations. These toads often die when humans relocate them outside of their home territory, and it’s common for diseases to spread when smuggler store them together.

All toads secrete toxins, which originally evolved to keep their bodies moist and later evolved as a method of self-defense. What sets the Sonoran Desert toad apart is its unique ability to convert bufotenine, a compound produced by many toads, into 5-MeO-DMT. When threatened, the toad excretes its potent mixture from glands behind each eye and on its legs as a defense mechanism.

The Sonoran Toad’s Toxic Friends

The Sonoran Desert toad isn’t the only species with psychedelic potential. The giant monkey frog from the Amazon Basin produces a toxic secretion called kambô. Its use as a psychedelic is debated. But some users report spiritual experiences similar to those induced by classic hallucinogens, Nevertheless, kambô does not activate the 5-HT2A receptor, a characteristic of traditional psychedelics. Indigenous populations have used kambô for centuries in shamanistic rituals to boost stamina.

Humans have a long history of seeking altered states of consciousness, often guided by the natural world. But our pursuit of these experiences should never come at the expense of the very creatures that offer us these extraordinary glimpses into other realms.

It’s important to balance our curiosity and respect for the natural world with conservation efforts to protect these species and their habitats from exploitation.

If you want to see and hear the toad in question, we found a reliable YouTube video. When it comes to this species, we urge you only to get information from reliable sources!

WTF Fun Fact 13474 – Once There Were No Mosquitos in Hawaii

by

Believe it or not, there were no mosquitoes in Hawaii until the 19th century.

In its early days, Hawaii was a natural utopia, a paradise that existed free of the annoying whine and itchy bites of mosquitoes. Native flora and fauna thrived without the interference of these bloodsuckers. This absence wasn’t by chance, though. Hawaii’s remoteness, surrounded by thousands of miles of open ocean, formed a natural barrier that kept mosquitoes, among other things, away.

The End of No Mosquitos in Hawaii

Everything changed in the early 19th century when mosquitoes finally found their way to the Hawaiian Islands. Brought inadvertently by humans, the first recorded arrival was in 1826 on a trading ship. The invasive species soon adapted to the tropical climate and began to breed in the islands’ plentiful standing water sources, spelling trouble for both the local ecosystem and the human population.

The Mosquito’s Impact on the Hawaiian Ecosystem

Once mosquitoes gained a foothold, the repercussions were significant. Hawaii’s native bird populations suffered drastically. Mosquitoes brought avian malaria and avian pox, diseases to which the indigenous birds had no immunity. This resulted in a significant decrease in bird populations, leading some species to the brink of extinction. The Hawaiian honeycreeper, for example, experienced a substantial decline, with some species entirely wiped out.

Humans also felt the effects of the mosquito invasion. Initially, the islands’ residents were not accustomed to the nuisance of mosquitoes. However, more than just a nuisance, mosquitoes brought diseases like dengue fever and the Zika virus, threatening public health. Moreover, tourism, a significant part of Hawaii’s economy, took a hit as the presence of these pests and the diseases they carried became a deterrent for some tourists.

Current Efforts to Control Mosquito Populations

Today, efforts are underway to control mosquito populations and mitigate their impacts on Hawaii’s ecosystem. Measures such as eliminating standing water, using mosquito repellents, and introducing mosquito predators like dragonflies are part of the strategy. In addition, genetic modification technologies are being explored to reduce the ability of mosquitoes to reproduce or carry diseases.

The late arrival of mosquitoes in Hawaii is a stark reminder of the profound effects human activities can have on isolated ecosystems. Even an event as seemingly minor as a mosquito stowing away on a ship can disrupt a delicate balance, causing ripple effects that last for centuries.

Gone are the days when there were no mosquitos in Hawaii. As the islands grapple with the ongoing challenges presented by mosquitoes, this tale provides valuable lessons about the importance of protecting the world’s unique environments from invasive species.

WTF Fun Fact 13468 – The Streisand Effect

by

The term “Streisand Effect” may sound like it’s tied to some groundbreaking scientific discovery, but it’s actually named after the famous American singer and actress, Barbra Streisand. The term was coined in 2005 and refers to an unexpected and counter-intuitive social phenomenon where efforts to suppress or censor information backfire, leading to the unintended consequence of the information being widely publicized and shared even more than before.

2. The Origin Story

The Streisand Effect was named after an incident involving Barbra Streisand in 2003. A photographer named Kenneth Adelman had taken aerial shots of the California coastline for the California Coastal Records Project. He intended to document coastal erosion. One of these photographs included Streisand’s Malibu home. Despite the image being among 12,000 others and not specifically identifying her home, Streisand sued Adelman and the associated website for $50 million. She asserted that the photo violated her privacy rights.

However, Streisand’s efforts to maintain her privacy unintentionally drew more attention to the photograph. Prior to the lawsuit, the picture had only been downloaded from Adelman’s website six times; two of those downloads were by Streisand’s lawyers. After the lawsuit became public, the photograph gained widespread attention, receiving over 420,000 views in the following month.

3. Examples of The Streisand Effect in Action

Since the original incident, the Streisand Effect has occurred multiple times, especially in the digital age where information spreads quickly.

In 2008, a blog post detailing weaknesses in the Church of Scientology’s operations resulted in a takedown notice from the Church. Instead of disappearing, the information proliferated across other sites, leading to more awareness and criticism of the Church.

In 2009, the UK law firm Carter-Ruck tried to suppress a report about its client Trafigura, a commodity trading company involved in a toxic waste scandal. A gag order initially prevented The Guardian from reporting on the issue. A judge lifted the order after intense public outcry and online sharing of the information.

The Power of the Streisand Effect

The Streisand Effect highlights the immense power of the internet and social media in the spread of information. It also illustrates the backlash that can result from attempts to suppress it. The digital age has shifted control over information from those with traditional power (like celebrities, corporations, governments) to the broader public.

This phenomenon raises important considerations for public figures, companies, and institutions in how they handle potentially damaging information. Attempting to suppress such information can often make matters worse. It can even cause more harm to a reputation than ignoring it or addressed it openly.

WTF Fun Fact 13467 – The Baghdad Battery

by

When we think about the birth of electricity, names like Benjamin Franklin, Thomas Edison, and Nikola Tesla might come to mind. But if we venture even further back in time, we stumble upon a curious artifact known as the Baghdad Battery.

This ancient piece, found in the vicinity of modern-day Iraq and believed to date back to the Parthian or Sassanid era (between 225 BC and AD 650), challenges our understanding of technological development. It’s a story that connects the ancient world with our modern one in a fascinating tale of science and history.

Discovery of the Baghdad Battery

The story of the Baghdad Battery begins in 1936. German archaeologist Wilhelm König discovered a set of 12 peculiar artifacts in the basement of the National Museum of Iraq. The artifacts, assumed to be about 2,000 years old, consisted of terracotta pots with a copper cylinder and a single iron rod inside.

Each “battery” was about 14 cm high, with a one-inch-wide mouth. The copper cylinder, carefully soldered with a 60-40 lead-tin alloy, encapsulated the iron rod. Evidence of an acidic residue such as vinegar or wine in some of the pots led König to propose that these were ancient electric cells.

The theory suggests that when the jars were filled with an electrolytic solution (like vinegar or lemon juice), they produced a potential difference between the copper and the iron — about 1.1 volts. This setup is remarkably similar to a basic school experiment to create a simple voltaic cell.

The primary controversy lies in the purpose of these devices. Some researchers propose that these ancient cells powered electroplating objects with gold. Others suggest a more spiritual role, possibly linked to pain relief. The sensation of a mild electric shock could have been interpreted as a divine intervention or magical experience.

Debates and Controversies

The theory of the Baghdad Battery as a tool for electroplating or electrotherapy is not without its critics. Skeptics argue that there’s no recorded evidence that ancient people had knowledge of electricity. Furthermore, there is no evidence of wires, conductors, or additional devices that could demonstrate a practical application for this alleged ancient technology.

Another point of contention lies in the design. If the intent was to generate an electric current, the iron rod would have quickly corroded due to the acidic solution. However, some of the recovered artifacts still have uncorroded iron rods, suggesting they might never have been used as proposed.

WTF Fun Fact 13463 – Dog Poop DNA Test

by

If you live near a dog owner who doesn’t clean up after their pup, you can now get a dog poop DNA test to track them down.

A company named PooPrints is one of a growing number of companies that will let you send in dog poop for detective work.

Poo Prints Dog Poop DNA Test

The concept is simple, yet genius. When dogs move into a participating apartment complex or housing community, they undergo a quick DNA cheek swab. The information is then stored in PooPrints’ vast database. If someone stumbles across an abandoned pile of dog poop, a small sample can be sent to PooPrints for DNA analysis.

With the precise accuracy of these tests, annoyed residents can ask their apartment complex to quickly ID and appropriately dealt with a rude dog owner, usually through a fine.

The man behind the mission, Tom Boyd, found inspiration in his own annoyance with irresponsible pet owners. He transformed his personal pet peeve into a thriving business with PooPrints now serving clients across the US, Canada, and the UK.

Unleashing Controversy

But this is more than just a business. PooPrints is making a significant environmental impact. According to the Environmental Protection Agency, pet waste is as toxic to the environment as chemical spills. It’s not just an eyesore; it’s a health hazard. By helping to enforce clean-up rules, PooPrints aids in reducing these environmental hazards.

However, as with any disruptive idea, PooPrints has also seen its share of controversy. For example, people have raised privacy concerns about collecting and storing pet DNA. Critics also point out that fines can disproportionately impact lower-income pet owners.

Despite the debate, PooPrints continues to grow. While the concept might seem absurd at first, it’s an innovative solution to an everyday problem. By holding pet owners accountable, PooPrints is turning unwelcome dog poop into a tool for cleaner, more harmonious communities.

WTF Fun Fact 13458 – Taxidermied Bird Drones

by

Researchers often look to nature for inspiration when designing machines and devices – now scientists from the New Mexico Institute of Mining and Technology are taking this concept a step further, building taxidermied bird drones.

Why use taxidermy bird drones?

The idea might seem disturbing or bizarre at first. A decade ago, a Dutch artist, Bart Jansen, had stirred conversation by turning a deceased, taxidermied cat into a furry quadcopter. However, the researchers from New Mexico Tech have a practical reason for their unique approach to creating ornithopters—drones that fly by flapping their wings like a bird.

Their aim is to harness the flight capabilities of birds whose lightweight bodies and flexible feathers give them remarkable maneuverability that outmatches the most sophisticated aircraft we’ve built.

According to a study presented at the American Institute of Aeronautics and Astronautics SciTech 2023 Forum, using actual bird parts can offer significant advantages over artificial materials engineered to mimic bird behavior.

The researchers believe that their bird-built drones can effectively camouflage in the air, being more likely to be ignored due to their realistic appearance. These drones may not excel in performing complex aerial maneuvers like a living bird, but they could become an essential tool in espionage or wildlife study.

From stealth to espionage

One unique advantage of using bird feathers in these taxidermied bird drones is the stealth capabilities they offer. Unlike the noticeable hum of an electric motor propelling a typical drone, a bird drone with flapping feathered wings could potentially sneak up on targets quietly without alarming them. This would be particularly useful in studying and observing wildlife in their natural habitats, without disturbing their normal behaviors. Military applications could also benefit from the stealth properties of these feathered drones, providing an innovative approach to surveillance and reconnaissance.

The current bird-built drones, however, have limitations. Unlike real birds that use their muscles to flex and shape their wings for executing intricate aerial maneuvers, these drones can only flap their stiff wings up and down to stay airborne. The challenge for the researchers lies in advancing the technology to imbue their bird drones with greater agility in flight.

The research from New Mexico Tech presents an intriguing intersection of biology and technology, pushing the boundaries of how we perceive and utilize drones. As they continue to refine their design, these bird-built drones could revolutionize areas from espionage to wildlife observation. Yet, ethical considerations, including the use of taxidermied birds, will undoubtedly be part of the ongoing discourse as this technology evolves.

WTF Fun Fact 13457 – Crocodile’s Virgin Birth

by

In a scientific breakthrough, researchers have recorded the first known instance of a crocodile’s virgin birth. The female American crocodile lived in isolation for 16 years at a zoo in Costa Rica.

What’s the story behind the crocodile’s virgin birth?

This incredible discovery has revealed a surprising reproductive capability in crocodiles and could provide insight into their prehistoric relatives.

In 2018, the female American crocodile, despite her solitary existence, laid 14 eggs in her enclosure, which is not an uncommon occurrence among captive reptiles. However, things took an unexpected turn when, after three months of incubation, scientists discovered a fully formed, stillborn baby crocodile in one of the eggs.

Genetic analysis of the fetus revealed that this was a result of facultative parthenogenesis (FP), a type of reproduction that occurs without the genetic contribution of males. Essentially, the mother’s egg cell developed into a baby without being fertilized by a male’s sperm cell.

Facultative parthenogenesis explained

In FP, the process of egg cell formation divides a precursor cell into four cells. One of these becomes the egg cell, retaining key cellular structures and the gel-like cytoplasm, while the others contain extra genetic material. Interestingly, one of these cells acts like a sperm cell, fusing with the egg to facilitate fertilization.

While this type of reproduction, colloquially known as a “virgin birth,” has been documented in various species of fish, birds, lizards, and snakes, this is the first-known instance in a crocodile.

The American crocodile is a vulnerable species at risk of extinction. According to one hypothesis, FP may be more prevalent among species on the brink of extinction. The discovery of this unusual reproductive strategy could have significant implications for the conservation of endangered crocodile populations.

A glimpse into the prehistoric past

This astounding discovery in Costa Rica could also open new windows into the ancient past. As the study suggests, the “virgin birth” phenomenon might offer insights into the possible reproductive capabilities of extinct archosaurian relatives of crocodilians and birds, specifically members of Pterosauria and Dinosauria that roamed the earth during the Triassic Period about 250 million years ago.

WTF Fun Fact 13453 – Shark GPS Tracker Draws Shark

by

A great white shark with a GPS tracker drew a shark in the waters off the eastern coast of North America. Was he “punking” researchers? Telling us he knows what we’re up to? Do sharks mysteriously swim in shark-shaped patterns? Or are we just seeing what we want to see?

Don’t answer that – it’s not as funny if you do.

The unconventional artist

Art and creativity are typically deemed human endeavors. But perhaps they also belong to the great white shark who unwittingly sketched a self-portrait, using tracking data as its brush.

Our artist is a mature male great white shark, named Breton by the OCEARCH team. He’s a frequent wanderer off the Atlantic Ocean coast of Long Island, New York. As part of the shark tracking initiative, he carries a tracker affixed to his dorsal fin. This tracker collects and relays data whenever the shark surfaces, providing an almost real-time map of the shark’s movement.

Did the shark GPS tracker draw a shark?

A May 2022 observation of Breton’s tracking data offered an unexpected delight to the researchers. It seemed as though Breton had swum in a pattern that mirrored the outline of a great white shark when seen from above.

OCEARCH shared the data on its social media, and the internet quickly took notice.

The tracking path captured not only the body’s curve but also the classic angular shape of the tail and the pectoral fins. It sure looks like a shark!

Coincidence or Design?

As fascinating as Breton’s journey may seem, it is essential to underline that the ‘self-portrait’ was purely coincidental. Sharks navigate based on instincts and sensory information, not a predetermined design. Sorry if you needed to be told that – but people have been studying sharks for a long time. That doesn’t mean we can’t enjoy the coincidence!

While the artistic byproduct is captivating, the primary purpose of tracking sharks like Breton is conservation. By learning about migration patterns, feeding areas, and breeding grounds, scientists can devise effective strategies to safeguard these creatures. The knowledge gained from such tracking can inform the establishment of marine protected areas and fishing regulations.

The good news is that Breton’s self-portrait can serve as a symbol for raising awareness about the threats facing great white sharks.

Issues like overfishing, habitat degradation, and climate change pose significant threats to these magnificent creatures. Breton’s story is an opportunity to engage the public and rally support for shark conservation.

WTF Fun Fact 13451 – Shape-Shifting Robot

by

You’ve seen robotic dogs, humanoid robots that can do backflips, etc. – but have you seen the new shape-shifting robots? Just what the world needs, right? Well…maybe!

Do shape-shifting robots really exist?

They do exist, but they’re small – and they’re certainly not a threat. Although we don’t exactly love the headline from EurekAlert “Watch this person-shaped robot liquify and escape jail, all with the power of magnets.” But whatever. Like all robots, they’re pretty cool, aside from their (granted, far-fetched) potential to destroy us all.

This robot can indeed transform, liquefy itself, slip into the smallest crevices, and then reassemble with absolute precision. The shape-shifting robot creators drew inspiration from a sea cucumber.

What do a sea cucumber and a shape-shifting robot have in common?

Sea cucumbers have a unique ability—they can alter their stiffness rapidly and reversibly. This is the fascinating biological phenomenon that the researchers hoped to replicate in their robotic system.

Traditional robots, with their rigid bodies, lack the flexibility to navigate small spaces. There are “softer” robots, but while they’re more pliable, are often weaker and harder to control. So, to overcome these challenges, the team aimed to create a robot that could oscillate between being a solid and a liquid.

The new breed of robot is an alloy of gallium—a metal with a low melting point—and includes embedded magnetic particles. The particles allow the robot to respond to magnetic fields, which scientists can use to control its movement and induce changes in its state—from solid to liquid and vice versa.

The team from Carnegie Mellon University christened their groundbreaking creation the “magnetoactive solid-liquid phase transitional machine.” Catchy!

The power of transformation

In a magnetic field, the robot can jump, stretch, climb walls, and even solder a circuit board. Its most impressive trick? The ability to liquefy and squeeze itself out of a mock prison—only to solidify once again on the outside. When in solid state, this robot can bear weights 30 times its own, demonstrating remarkable strength and flexibility.

Interestingly, the shapeshifting robot might have potential applications in the medical field. In a proof-of-concept experiment, the robot successfully removed a ball from a model of a human stomach. It quickly moved to the ball, melted around it, reformed, and exited the model stomach—ball in tow.

Although gallium was the metal of choice in these experiments, other metals could be introduced to adjust the melting point for real-life applications.

Future applications

Looking ahead, the gallium robots could serve a variety of purposes. From assembling and repairing hard-to-reach circuits to acting as a universal screw that melts and reforms to fit any socket, the possibilities seem endless.

The technology might have significant biomedical applications as well. For instance, these robots could deliver drugs inside a patient’s body or remove foreign objects. However, before any in-human application, tracking the robot’s position within a patient’s body is a hurdle scientists need to overcome.

Who knows, maybe a doctor will ask you to swallow a shape-shifting robot someday. What a thing to look forward to!

WTF Fun Fact 13450 – The Hunter Gatherer Woman

by

Archaeologists have discovered the hunter-gatherer woman. So while our general assumption is that men took on the role of hunters in prehistoric times while women gathered resources and cared for offspring, recent discoveries are challenging this age-old belief. We now have a new picture of gender roles in prehistoric societies.

Archaeological insights into the hunter gatherer woman

The discovery of a 9,000-year-old female skeleton buried with her hunting toolkit in the Andean highlands suggests women might have hunted big game right alongside men. The burial site, located in what is now Peru, was rich in hunting artifacts, from spear points to butchering tools.

Upon examining the skeleton and associated tools, archaeologists concluded that this prehistoric woman was likely a hunter. This conclusion stemmed from the diversity of hunting tools buried alongside her, which would have been used to kill and butcher large game, not just small animals.

Broadening perspectives

The discovery sparked a wider investigation, prompting researchers to reanalyze burials from around the same period. Their analysis yielded more surprises: out of 429 burials from across the Americas, they found 27 individuals associated with big-game hunting tools, and 11 of these were women. This data suggests that in these communities, both men and women were likely to be hunters.

These findings upend the prevailing narrative of prehistoric gender roles. The assumption that men were the hunters while women were the gatherers has shaped our understanding of prehistoric societies for generations. However, these new findings suggest a more equitable distribution of roles than previously thought.

Implications for our understanding of prehistoric societies

These findings have crucial implications for our understanding of social organization and labor division in ancient hunter-gatherer societies. They not only shift our perspective on gender roles but also reshape the way we interpret archaeological data. For instance, when we unearth hunting tools in future excavations, we should consider the possibility that they may have belonged to women.

In the face of new archaeological evidence, we are rethinking long-held assumptions about prehistoric societies. The discovery of women hunters suggests a more egalitarian division of labor than previously assumed. As we continue to unearth clues from our past, we gain a richer, more nuanced understanding of human history.

WTF Fun Fact 13446 – Danish AI Political Party

by

The Synthetic Party is a Danish AI political party led by an AI chatbot named Leader Lars.

How does an AI political party work?

Denmark’s political landscape is making an intriguing pivot towards artificial intelligence. Leader Lars was brought to life by artist collective Computer Lars and the non-profit art and tech organization MindFuture Foundation. Is this a new era in political representation?

The Synthetic Party, established in May 2022, aspires to represent the values of the 20% of Danes who do not vote. This AI chatbot is not just a figurehead. It’s equipped with policies drawn from Danish fringe parties since 1970. And its human members are committed to executing these AI-derived platforms.

Why involve an AI in politics?

The Synthetic Party seeks to represent data from all fringe parties striving for a parliamentary seat. It’s a novel concept that allows individual political visions, usually limited by financial and logistical constraints, to gain representation. The unique aspect of this political approach is the interaction between citizens and Leader Lars on Discord, a platform where people can speak directly to the AI. This feature fosters a unique form of democratic engagement.

The party’s AI-led political approach raises questions about the viability and accountability of machine learning in government. For instance, can an AI truly grasp and represent human needs and values? How do we hold an AI accountable for its decisions? The Synthetic Party’s response to these questions lies in the transparency and auditability of AI decision-making processes.

Party policy

The Synthetic Party’s policies are bold, to say the least. From establishing a universal basic income of 100,000 Danish kroner per month (equivalent to $13,700, and over double the Danish average salary) to creating a jointly-owned internet and IT sector within the government, the party seeks to innovate and challenge the status quo.

Crucially, the Synthetic Party is not about putting a chatbot in charge. Instead, it’s about exploring the democratic potential of AI and machine learning. The party sees AI as a tool to amplify and understand a wide range of opinions, even if those opinions sometimes contradict each other.

In addition to offering fresh political perspectives, the Synthetic Party aims to raise awareness about the role of AI in our lives and the importance of AI accountability. For example, it advocates for the addition of an 18th Sustainable Development Goal. This would focus on the relationship between humans and AI to the United Nations’ SDGs.

The Synthetic Party seeks to promote a more democratic, accountable, and transparent use of AI in politics. The party needs 20,000 signatures to run in the 2023 November general election. If it gets those, it could introduce a novel form of political representation in Denmark. It would be one that goes beyond a simple figurehead and instead uses AI as a tool for political change.

Our sense of smell is strongest at night. So if you feel like your pets seem extra smelly, or your bubble bath is a bit too fragrant in the evening hours, you’re not just imagining things. You’re picking up on scents that are somewhat dampened during the day.

Why is smell important?

Smell influences everything from taste perception to memory formation. However, what you may not know is that our ability to detect and discern scents fluctuates throughout the day, peaking during the late hours. This might seem trivial or even surprising, but it is a fascinating aspect of our biology. And it’s linked to our circadian rhythms.

The circadian rhythm is an internal process that regulates our sleep-wake cycle. It repeats roughly every 24 hours and impacts many physiological processes, including hormone release, body temperature, and various neural functions. Interestingly, this includes our olfactory sensitivity – our ability to perceive smells.

During the daytime, our brains process a multitude of sensory inputs. The sights, sounds, and tactile sensations we encounter are processed and analyzed, taking up significant neural resources. Consequently, our sensitivity to smells is somewhat overshadowed by this barrage of information.

Why is our sense of smell strongest at night?

However, the scenario changes at night. As the environmental stimuli decrease and our focus shifts inward, our sensitivity to smells becomes more pronounced. This shift is likely due to changes in body temperature and brain activity that occur during our sleep-wake transition.

The nocturnal enhancement of olfaction has implications beyond being a mere biological curiosity. For one, it directly influences our sleep quality. We are more susceptible to disturbances from unpleasant or potent odors at night. Therefore, the significance of maintaining a fresh and pleasant sleeping environment becomes clear for a good night’s sleep.

Moreover, this increased olfactory sensitivity might have roots in our evolutionary history. Our ancestors needed to be alert to dangers like predators or fires, especially during the night. A heightened sense of smell would have been advantageous in such scenarios, leading to better survival and reproductive success.

On a practical level, this knowledge can be advantageous to various industries, especially those involved in perfume and scent manufacturing. By understanding our olfactory system’s functioning, businesses can tailor their products for maximum impact during the evening hours.

WTF Fun Fact 13443 – Dead Fruit Flies

by

When fruit flies see or smell their dead comrades, their own lives are cut short. Talk about putting a damper on your day!

Fruit flies stress after seeing other dead fruit flies

If you’re a fruit fly, seeing one of your fallen is not just unsettling. It’s downright harmful to your health. Despite their diminutive size, experience stress and negative health effects when they witness the remains of their kin.

Neuroscientists have found that when fruit flies (Drosophila melanogaster) see their deceased fellow flies, specific brain cells are triggered.

And these aren’t just any brain cells. They are neurons that respond to visual stimuli, known as visual projection neurons (VPNs). These cells relay information from the flies’ eyes to their brains, helping them interpret and react to what they see.

What’s going on in a fruit fly’s brain?

But let’s add a pinch of intrigue to the mix. These neuroscientists didn’t stop at merely identifying the type of neurons involved. They zeroed in on the specific group of neurons that reacts to the sight of dead flies. The neurons in question are part of a cluster known as the “globus pallidus.” This is an area associated with movement and learning.

These scientists have discovered the precise neighborhood in the fruit fly’s brain where the “dead fly sighting stress response” takes place.

So, what happens when these neurons fire? In short, they trigger a series of stress responses that have a tangible impact on the fruit flies’ health and lifespan. As the sight of a dead fellow fly becomes ingrained in the fly’s brain, it alters the expression of stress-related genes, tipping the physiological balance and leading to a shorter lifespan.

This discovery has raised intriguing questions about the evolution of empathy and social responses in insects. While fruit flies may not experience empathy in the way humans do, their stress response to seeing dead comrades suggests a level of social awareness. This raises the question: why would such a response evolve? One possibility is that the sight of death serves as a warning signal, indicating the presence of potential threats or diseases, thus prompting the fly to modify its behavior.

However, this remarkable finding does more than just throw light on fruit flies’ stress responses. It could also contribute to our understanding of how human brains process stress and trauma. Humans, like fruit flies, have neurons that respond to visual stimuli. Therefore, these findings could lead to a better understanding of how our brains respond to stressful visual experiences, and potentially inform treatments for stress-related disorders.

WTF Fun Fact 13442 – We Have More Bacterial Cells Than Human

by

The human body contains more bacterial cells than human cells. Weird, right?

The majority of the cells that constitute “you” are, in fact, not human. They are microscopic organisms that are hitching a ride, making a living off your body. It might sound like science fiction, but this is a confirmed scientific fact. The human body contains ten times more bacterial cells than human cells.

How can we contain more bacterial cells than human cells?

Now, before we allow our imagination to scare us into a frenzy, let’s unpack this a bit.

These bacterial cells, collectively known as the human microbiota, live mostly in harmony with our bodies. We provide them with a suitable habitat, and they return the favor by aiding in bodily functions like digestion and immune response. Our gut houses the vast majority of these organisms.

This raises some provocative questions: With our bodies being made up predominantly of non-human cells, what does that imply about our identity? What actually makes us human?

How are we fully human if we contain so many non-human cells?

Biologically speaking, being human is about more than just the number of cells. Human cells, while fewer in number, are much larger and more complex than bacterial cells. So, in terms of volume and genetic material, we are predominantly human.

But the philosophical implications are still fascinating to consider. We ten to link our human identity to our biological makeup. But the massive presence of non-human cells introduces an intriguing paradox.

Science has often categorized organisms based on their cellular composition. However, this fact might prompt us to reconsider such traditional boundaries. We need to acknowledge the complex symbiosis that constitutes our “self.” We are, in essence, a walking, talking microbiome.

Teamwork makes the dream work

These non-human inhabitants of our body have a far-reaching impact on our health and well-being. There’s a dynamic relationship between our human cells and these bacterial cells. When this relationship is in balance, we thrive. But when it’s out of whack, we may face health issues. This fact has driven researchers to explore the potential of microbiota in shaping future treatments for various diseases.

Yet, as we learn more about our microbial inhabitants, we also uncover deeper layers of what it means to be human. Are we individual entities, or are we, as some philosophers might argue, a “superorganism” made up of numerous symbiotic relationships?

Indeed, we might be more ‘alien’ than we ever imagined, yet this very fact underscores our extraordinary complexity as living beings.

So next time you glance at your reflection, remember: You’re not just looking at ‘you.’ You’re seeing an intricate ecosystem.

WTF Fun Fact 13441 – Dopamine Reward Prediction Error

by

The concept of the dopamine reward prediction error is important for understanding the roots of learning, motivation, and even addiction. It’s all about how our brains respond to rewards (and how we get bored with the same reward over time).

What’s the point of dopamine?

Dopamine is a neurotransmitter (or “chemical messenger”) that plays a role in our brains’ reward system. In other words, it’s the star of the show when it comes to feelings of pleasure and satisfaction.

Think about how you feel when you sit down to your favorite meal. Or approach the counter with a long-sought item you saved up money to buy. Happy times! Right?

Well, one particularly interesting (and, frankly, kind of unfair) element of how dopamine functions is that once we already know what a reward will feel like, our brains don’t send out as much dopamine. This is the concept of the dopamine reward prediction error.

What is the dopamine reward prediction error?

Let’s dive a little deeper.

Imagine you’re at a new restaurant for the first time. You order a dish you’ve never tried before. To your pleasant surprise, it turns out to be delicious. Your brain rewards you with a burst of dopamine, creating a sense of pleasure and satisfaction. In essence, your brain is saying, “Good job! Let’s remember this for next time.”

Now, let’s fast-forward to your next visit to the same restaurant. You order the same dish, this time expecting it to be tasty. But here’s the catch – when you take the first bite, your brain’s dopamine release is less intense than the first time. This is because the pleasure derived from the meal was expected. This concept is known as reward prediction error.

Even when you’re eating your favorite meal, it may never taste as marvelous as the first time you had it.

What’s going on in the brain when there’s a dopamine reward prediction error?

Reward prediction error is your brain’s way of comparing the predicted reward (expectation) with the actual outcome. When reality exceeds your expectations, a positive prediction error occurs. And your brain increases its dopamine release.

Conversely, when the actual reward is less than expected (as so often happens in life!), a negative prediction error occurs. Few things are as good as we imagine them to be, and this results in a decrease in dopamine release. (Why did our brains stop playing nice?!)

Why is your brain being a jerk about dopamine?

This dopamine release mechanism seems to play a role in how we adjust our predictions based on outcomes. Technically, it helps us learn from our mistakes and successes. But clearly, it’s not all fun and games. Your brain doesn’t give you a trophy every time you do something good (at least not a big one).

This dopamine-driven learning process can be exploited in harmful ways too. Just think about addiction.

Some drugs generate a significant positive prediction error in our brains. In other words, we take them and (if we survive) we may get a massive release of dopamine that makes us feel great. But this tricks the brain into overvaluing the substance. And this can drive intense cravings and compulsive behavior.

The down side of dopamine

Whether it’s drugs or food or destructive behavior, repeated exposure leads to a decrease in the dopamine response. Unfortunately, this means our bodies require more of the substance to achieve the same effect. That’s addiction.

But here’s the good news – understanding the way our brains respond to reward prediction errors can open up possibilities for new therapeutic approaches. It is helping researchers develop interventions that ‘retrain’ the brain’s reward system to reduce the impact of negative prediction errors and boost our ability to learn from positive experiences.

WTF Fun Fact 13439 – The Dog Days of Summer Explained

by


Does the phrase “Dog Days of Summer” conjure images of lethargic canines lazing in the heat? Well, the origins of this term reach far beyond our four-legged friends and into space.

What are the dog days of summer?

Ok, technically, it does have to do with a dog – Sirius, the Dog Star. Sirius is part of the constellation Canis Major, and it’s the brightest star in the Earth’s night sky.

The term “Dog Days” stems from the ancients, both Greeks and Romans, who noticed the coincidence of the hottest time of the year with the period when Sirius rose and set with the Sun. They hypothesized that the added radiance of Sirius was the cause of the intensified summer heat. Thus the phrase “Dog Days” in reference to Sirius’s constellation.

But the “Dog Days” are more than just a celestial phenomenon and a synonym for summer swelter. They have cultural and historical significance dating back thousands of years. The Greeks, for instance, saw the period as a time of potential disaster, heralding fever, catastrophe, and even the downfall of empires.

Wobbling dog days

Fast forward to the present, and the “Dog Days” still persist in our lexicon. However, due to a phenomenon called precession (the slow wobble of Earth’s rotational axis), the dates during which Sirius rises and sets with the Sun have slowly shifted over centuries. Yet, the phrase “Dog Days” remains tethered to the heart of the summer. It’s recognized in the Northern Hemisphere primarily from July 3 to August 11.

The warmest days of summer, those long afternoons that stretch languidly towards the evening, are connected to a distant cosmic spectacle occurring about 8.6 light-years away. That is the beauty of astronomy and the power of human observation, linking us to the stars and the seasons in unexpected ways.

So, next time you’re feeling the heat of summer bearing down, spare a thought for Sirius and its ancient connection to these sultry days. The “Dog Days” are a cosmic link, a reminder that even on the hottest days of summer, we are all under the same sky.
