WTF Fun Fact 13668 – Chimpanzees Go Through Menopause

by

Chimpanzees go through menopause? Well, it makes sense considering all our similarities, right?

Menopause has been a phenomenon largely associated with human existence. However, recent findings have expanded our understanding, revealing that wild female chimpanzees undergo a similar process. This groundbreaking discovery challenges our previous beliefs and opens a new chapter in evolutionary biology.

Finding Out That Chimpanzees Go Through Menopause

Over two decades of meticulous research in Uganda’s Kibale National Park have provided us with invaluable insights. Scientists monitored 185 female chimpanzees, observing their reproductive patterns and hormonal changes. The study’s longevity and depth offer a rare glimpse into the lives of these fascinating creatures.

The study found a clear decline in fertility as the chimpanzees aged, particularly after the age of 30. Notably, none of the observed females gave birth beyond the age of 50, marking a distinct phase akin to human menopause. This shift is not merely a reproductive halt but a complex biological transition.

Mirroring human menopause, older female chimpanzees exhibited significant hormonal changes. An increase in follicle-stimulating hormone and luteinizing hormone, coupled with a decrease in estrogens and progestins, paints a picture strikingly similar to the human experience.

These hormonal fluctuations are more than mere numbers; they signify a profound shift in the chimpanzee’s life stage.

Implications for Evolutionary Biology

The discovery of menopause in wild chimpanzees raises intriguing questions about the evolutionary roots of this phenomenon. If our closest living relatives also experience menopause, it suggests a shared evolutionary path. This revelation compels us to reconsider the “grandmother hypothesis” and other theories explaining why certain species live significantly beyond their reproductive years.

Is the occurrence of menopause in the Ngogo chimpanzee community an anomaly or a common trait among other communities? Factors such as abundant food supply and fewer predators in Ngogo might contribute to their longer lifespans and the occurrence of menopause. To understand this better, comparative studies across various chimpanzee habitats are essential.

The Grandmother Hypothesis and Kin Competition

The “grandmother hypothesis,” suggesting older individuals assist in raising their grandchildren, doesn’t quite fit the chimpanzee social structure. An alternative theory is the “kin competition” hypothesis, where ceasing reproduction might reduce competition for resources among related individuals. Understanding the social dynamics of these primates is key to unraveling the purpose and evolution of menopause.

Expanding research to include bonobos, another close relative to humans, could provide further insights into the evolution of menopause. Do these primates also experience a similar phase, and if so, what can it tell us about our ancestral lineage?

WTF Fun Fact 13667 – AI Predicts Life Events

by

Artificial intelligence (AI) continues to push the boundaries of what we believe is possible – in fact, now AI predicts human life events.

A groundbreaking study recently revealed the potential of AI to forecast significant life occurrences with notable precision.

AI Predicts Life’s Complex Patterns

At the heart of this innovative research is a model known as “ife2vec.” This transformative AI tool was trained using vast amounts of data about people’s lives. This includes their residence, education, income, health, and work conditions. By employing ‘transformer models’ akin to the renowned ChatGPT, life2vec systematically organized this data to predict future events. This includes their time of death.

The researchers’ approach was to treat human life as a sequence of events, much like words in a sentence. This method allowed the AI to identify patterns and make predictions about future occurrences. Surprisingly, life2vec demonstrated a superior ability to predict outcomes such as personality traits and time of death compared to other advanced neural networks.

The Ethical Implications of Predictive AI

The promise of predictive AI in enhancing our understanding of life patterns is undeniable. But it also raises significant ethical questions. Issues around data protection, privacy, and potential biases inherent in the data are crucial considerations. Before such models can be applied in practical settings, like assessing individual disease risks or other significant life events, these ethical challenges must be thoroughly understood and addressed.

Looking ahead, the research team envisions incorporating various data forms into their model, such as text, images, or information about social connections. This expansion could revolutionize the interaction between social and health sciences, offering a more holistic view of human life and its potential trajectories.

WTF Fun Fact 13663 – Dog Longevity Drug

by

For dog lovers, the prospect of a dog longevity drug sounds fantastic. Who doesn’t want their furry friends to live longer, healthier lives?

Recent developments from a San Francisco-based biotech company, Loyal, bring this dream closer to reality. They’ve announced an anti-aging drug for dogs that has cleared its first hurdle for FDA approval. This marks a pivotal moment in veterinary medicine, as it’s the first time the FDA has shown openness to endorsing longevity drugs for pets.

Dog Longevity Drug Holds Promise of Longer Lives for Man’s Best Friend

Loyal’s groundbreaking drug, LOY-001, targets a growth and metabolism hormone called IGF-1. This hormone, linked with size, appears in higher levels in larger dogs and lower in smaller ones. Studies on other species suggest inhibiting IGF-1 can increase lifespans. LOY-001 is aimed at healthy dogs over seven years old and weighing more than 40 pounds. Administered every three to six months by a vet, it holds the potential to slow down the aging process in dogs.

Parallel to this, Loyal is developing LOY-003, a daily pill form of the treatment. CEO Celine Halioua emphasizes that they’re not creating immortal dogs. The goal is to slow their rate of aging, thus maintaining a healthier state for a longer period.

As promising as these developments are, they raise significant ethical questions, particularly concerning the quality of extended life for these animals. Veterinarian Kate Creevy, involved in a similar trial for an anti-aging drug called rapamycin, stresses the importance of ensuring that any extended lifespan is accompanied by good health and quality of life.

Moreover, the human manipulation of dogs through selective breeding, which may have contributed to accelerated aging in larger breeds, underlines the ethical complexities in altering canine aging processes.

Trials and the Future of Canine Health

Loyal plans to start a large clinical trial for LOY-001 with around 1,000 large and giant dogs by either 2024 or 2025. The ultimate aim is to have a market-ready product by 2026. This trial not only represents a major step in veterinary medicine but also opens doors to understanding aging in more complex organisms like humans.

The success of Loyal’s drug could potentially revolutionize how we approach canine health and aging. It offers a glimpse into a future where our canine companions can enjoy longer, healthier lives alongside us. However, it’s crucial to balance this scientific advancement with ethical considerations to ensure the well-being of these beloved animals.

WTF Fun Fact 13662 – What Shapes Our Worldview

by

Conventional wisdom often suggests that what shapes our worldview is significantly impacted by our background. Specifically, it’s a common assumption that privilege, encompassing factors like socioeconomic status, health, and safety, heavily influences one’s perspective of the world.

However, recent research from the University of Pennsylvania challenges this notion, revealing surprising insights about the relationship between privilege and a positive worldview.

Unraveling Assumptions about What Shapes Our Worldview

This intriguing study, conducted by The Primals Project at Penn’s Positive Psychology Center, looked into primal world beliefs (or “primals”). Primals are fundamental beliefs about the world, such as viewing it as progressing or declining, harmless or threatening, interesting or boring.

Contrary to expectations, the study found that positive primals were not strong indicators of a privileged background.

Methodology and Results

Researchers surveyed over 14,000 individuals, examining their agreement with statements like “Life overflows with opportunity and abundance” and “The world is going downhill.” They also asked laypeople and psychology researchers to predict how different groups would respond based on their socioeconomic status, neighborhood safety, and other factors.

The predicted correlation between privilege and positive worldviews was significantly higher than the actual survey results. This disconnect suggests that positive worldviews may not be as closely tied to privilege as previously thought.

Shifting Perspectives on Trauma and Privilege

The study’s findings indicate that experiencing hardship or adversity doesn’t necessarily result in a negative view of the world.

For example, patients with cystic fibrosis showed a slightly more positive worldview compared to controls. This counters the narrative that those facing significant challenges are destined to view the world negatively.

Interestingly, the study found that women were slightly more likely to view the world as safe, defying the conventional assumption that women perceive the world as more dangerous due to societal and safety concerns.

The University of Pennsylvania’s study opens up new avenues for research. Teams are exploring genetic components and other factors that might influence one’s primal beliefs. With numerous independent research efforts underway, there’s a growing interest in understanding the origins and impacts of these fundamental worldviews.

WTF Fun Fact 13661 – Faith and Risk Taking

by

A recent study from York University’s Faculty of Health reveals an intriguing link between faith and risk-taking. The research, led by Assistant Professor Cindel White, looked into how beliefs about a protective God influence Christians’ willingness to take risks.

The study, published in the Journal of Experimental Social Psychology, suggests that the belief in a benevolent deity can boost confidence in pursuing uncertain or potentially dangerous activities.

Findings About Faith and Risk Taking

White, along with collaborators Chloe Dean and Kristin Laurin from The University of British Columbia, focused on Christian Americans known for their belief in a protective God. The study avoided risks with moral connotations, like drug use, and instead examined ‘morally neutral’ risks.

These included recreational activities like mountain climbing and life decisions such as relocating for a job. The research revealed a reliable connection between these beliefs and an increased willingness to take such risks.

The findings do not necessarily suggest that religious individuals are more inclined to take risks than non-religious people. However, they highlight the role of religious beliefs in creating a sense of safety and positivity. Belief in a protective God appears to help believers cope with life’s uncertainties and stressors. This sense of security and positive outlook may encourage them to seize opportunities they might otherwise avoid.

Understanding the Psychological Safety Net

The study provides insights into how religious beliefs function as coping mechanisms. For many believers, the idea of a protective God offers a psychological safety net.

This belief may empower them to face challenges and uncertainties with more confidence. It’s not just about risk-taking; it’s about how faith shapes the approach to life’s varied situations.

The research has significant implications for understanding the decision-making process of religious individuals. It suggests that their faith could subtly influence choices in everyday life, from career moves to leisure activities.

This understanding could be crucial for psychologists, counselors, and even employers in recognizing the factors that drive the actions and choices of religious individuals.

Broader Perspective on Religious Beliefs

These findings open up a broader perspective on the role of religious beliefs in modern society. They shed light on the nuanced ways faith intersects with daily life, influencing not just moral decisions but also personal and professional risks.

As society becomes increasingly aware of diverse belief systems, such insights are vital for fostering understanding and respect across different cultural and religious backgrounds.

WTF Fun Fact 13660 – Blue Light and Sleep

by

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

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

Blue Light and Sleep

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

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

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

Testing the New LEDs

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

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

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

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

Towards a Brighter Future with Blue Light

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

WTF Fun Fact 13659 – Hawaii Snow

by

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

Hawaii Snow

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

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

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

Hawaii’s High-Altitude Snow

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

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

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

El Niño’s Potential Impact

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

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

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

WTF Fun Fact 13658 – Viking Dentistry

by

You probably haven’t pondered Viking dentistry. However, a recent study at the University of Gothenburg revealed that Viking dental practices were surprisingly advanced.

The study examined 3,293 teeth from 171 individuals in Varnhem, Sweden, dating back to the Viking Age. This region is renowned for well-preserved skeletal remains, offering a unique glimpse into ancient dental health.

Caries and Tooth Loss in Viking Dentistry

The findings, published in PLOS ONE, show a widespread occurrence of dental issues among the Vikings. About 49% of the population had one or more caries lesions, with 13% of adult teeth affected, often at the roots. Interestingly, children’s milk teeth were free from caries. Adults frequently experienced tooth loss, averaging a 6% loss over their lifetimes, excluding wisdom teeth.

These results suggest that tooth infections and aches were common, likely impacting daily life.

The Vikings weren’t just suffering in silence; they actively attempted dental care. Evidence of toothpick use, front teeth filing, and even treatment for infected teeth were found. Molars showed filed holes from the crown to the pulp, probably to relieve toothache caused by infection.

This method mirrors modern dental treatments, where drilling into infected teeth relieves pressure. It’s unclear whether Vikings conducted these procedures themselves or sought help.

Cultural Significance of Teeth

Filed front teeth, found predominantly in males, may have served as identity markers. This practice indicates that teeth held significant cultural importance in Viking society. The study suggests that Viking Age dentistry might have been more sophisticated than previously thought, with a better understanding of oral health than assumed.

This study offers more than just a medical perspective; it sheds light on the cultural aspects of Viking life. The care and attention given to teeth, from practical health to aesthetic modifications, reflect a society that valued oral health and appearance.

Such findings challenge the stereotypical image of Vikings and offer a more nuanced view of their daily lives.

Advancements in Viking Dentistry

The dental techniques observed in Viking remains were not rudimentary. The evidence of infection treatment and cosmetic modifications speaks to a level of sophistication in their dental knowledge.

These practices show parallels with modern dentistry, highlighting an unexpected advancement in medical understanding during the Viking Age.

This groundbreaking research opens doors for further study into the health and cultural practices of ancient civilizations. Understanding the significance of oral health in Viking society could lead to more discoveries about their lifestyle, medical practices, and societal norms.

As we uncover more about the Vikings, our perception of them evolves from mere warriors to a complex society with advanced practices.

WTF Fun Fact 13655 – Ice Age Fire Art

by

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

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

The Paleolithic Animator and Ice Age Fire Art

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

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

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

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

Experimental Archaeology Sheds Light

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

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

The Role of Pareidolia in Ice Age Fire Art

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

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

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

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

Art as a Cultural Practice

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

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