WTF Fun Fact 13484 – Robots That Feel

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

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.

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

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

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

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

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

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

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

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.
