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 13449 – How Google reCAPTCHA works

by

Do you know how Google reCAPTCHA works? Maybe you’ve thought about it if you’ve ever been annoyed at having to prove to a machine that you’re human.

How Google reCAPTCHA works?

Google’s reCAPTCHA is a type of CAPTCHA, an acronym that stands for Completely Automated Public Turing test to tell Computers and Humans Apart. By serving as a litmus test for human-like interaction, CAPTCHAs are designed to protect websites against spam and online fraud. However, the “I am not a robot” prompt is far more than your run-of-the-mill CAPTCHA.

This advanced version does not solely rely on deciphering distorted text or identifying objects within images. When you click on that “I am not a robot” box, a risk analysis engine kicks into gear. It considers numerous factors that distinguish humans from bots.

This system notes the time it takes to interact with the checkbox and your IP address. It even tracks the peculiarities of your mouse movements. The mechanics of how you type, known as keystroke dynamics, is another vital piece of data used in this process.

All these factors collaborate to create a risk profile, allowing reCAPTCHA to make an informed decision about your human-ness.

Why clicking the box doesn’t prove you’re human

However, it’s worth addressing a common myth here. Some believe that when they engage with the “I am not a robot” checkbox, reCAPTCHA goes through their browsing history. It’s true that reCAPTCHA collects certain user data like cookies for abuse detection and prevention. However, it doesn’t comb through your individual browsing history. Google, the provider of reCAPTCHA, has robust privacy measures to ensure user data isn’t misused.

But that’s not to say that reCAPTCHA doesn’t consider your past interactions. As part of Google’s services, it can use cookies and session data to understand if you’ve frequently interacted with CAPTCHAs in the past. This information can influence the risk analysis engine’s decision-making (but it’s a far cry from inspecting your browsing history).

As we’ve uncovered, the “I am not a robot” checkbox is more than a simple statement. It’s a potent piece of technology.

As we continue to use the internet , it’s vital to understand these unseen mechanisms.

WTF Fun Fact 13448 – White Crustless Bread

by

Apparently, the best thing since sliced bread is white crustless bread.

Known as “mujipan,” or “crustless bread,” it has become a staple of Japanese kitchens, popular among both young and old. With its fluffy texture and mild flavor, it’s ideal for making sandwiches, toast, and various other dishes that the Japanese have ingeniously adapted to their cuisine.

Creating white crustless bread

The creation of crustless bread is not merely about slicing off the browned edges. Japanese bakers have perfected the technique of baking loaves where the crust is almost non-existent. This process involves using soft wheat flour, a lot of water, and a precise amount of yeast. The dough is then kneaded and left to rise multiple times before it’s finally baked at a lower temperature compared to traditional bread. The result is a soft, pillowy loaf with a very thin crust that is almost indistinguishable from the rest of the bread.

The crustless bread trend in Japan originated from the desire to create a perfect sandwich. In the Japanese context, sandwiches aren’t just a quick lunch option; they are an art form. The aesthetic appeal of the sandwich is as important as its taste. A sandwich made with crustless bread looks neat and elegant, the filling is the star, and nothing detracts from its visual appeal. This focus on visual presentation extends to all aspects of Japanese cuisine, from sushi to bento boxes.

Cutting off the flavor?

However, the popularity of crustless bread is not without its critics. Some bakers and food connoisseurs argue that the crust is where the flavor is. It’s the part of the bread that caramelizes during baking, creating a complex taste profile that the soft, white interior lacks. Yet, the demand continues to be strong, proving that its appeal goes beyond mere aesthetics.

Another interesting cultural aspect is the practicality of crustless bread. Japanese homes are often smaller with minimal storage space. The compact size of the loaves makes them easy to store. Additionally, they’re also more convenient for children and the elderly to eat.

In recent years, the trend has spread beyond Japan. Crustless bread is now available in various other countries, and the international market is growing. Its appeal lies in its convenience and its suitability for a variety of culinary applications, from breakfast toast to gourmet sandwiches.

Yet, despite its global reach, white crustless bread remains quintessentially Japanese. It encapsulates the Japanese approach to food, where taste, aesthetics, and practicality are all intimately connected. Like sushi, ramen, and matcha, this bread is a culinary innovation that reflects the culture from which it originated. In a world where cuisine is increasingly globalized, these unique cultural expressions provide a sense of connection to a particular place and way of life.

WTF Fun Fact 13447 – Law Student Caught Cheating

by

A law student was caught cheating on an exam – but the tactic was pretty creative. It didn’t involve AI; rather, it involved etching the answers onto pens.

Law student caught cheating, creatively

In academia’s high-stakes environment, students are often driven to develop ingenious, albeit misguided, strategies to gain an edge. An incident involving a Spanish law student serves as a perfect example. Their unorthodox approach to cheating sparked a wave of both surprise and begrudging admiration for the student’s inventiveness.

The student, instead of sticking to traditional study methods, opted for a novel approach: etching exam notes onto pens.

Yolanda de Lucchi, a law professor at the University of Malaga in Spain, found the blue Bic pens while cleaning her office recently. She recalled the incident on Twitter along with a photo.

Catching the culprit

During the nerve-racking examination, among the focused faces and hurried scribblings, one student stood out. The object of his intense scrutiny was not a perplexing question paper but an unassuming blue pen. What set this pen apart was its transformation into a tool of deception. Its sides, etched with minuscule text, carried a condensed version of course notes.

The ingenuity of the plan was remarkable but flawed. An observer, drawn by the student’s excessive focus on the pen, unveiled its secret. Methodical scrutiny of the pen exposed the cheat sheet, unraveled the student’s plan, and landed them in a situation that resulted in severe academic consequences.

Why not just study?

The irony of the situation wasn’t lost on the public. The creativity and determination that went into crafting this deceptive tool could have been well-spent in studying the law subject matter. Instead, the attempt at taking a shortcut led the student to face the consequences, which included repeating the entire academic year.

This tale of intrigue and downfall serves as a cautionary tale to students globally. The incident emphasizes that shortcuts, however ingenious, rarely lead to the desired destination in academia. A lesson learned the hard way by the student who, according to Professor De Lucchi, is “probably a lawyer today.”

The story underscores the importance of integrity and diligence in the face of academic pressure. The creativity exhibited in crafting the cheat-sheet could be commended if it were applied ethically and productively.

In the grand scheme of things, the tale of the etched pens sends a clear message: genuine success in education comes from honest hard work, not from clever shortcuts. The real reward of learning lies in the understanding of the subject matter, not merely in passing an exam.

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.

WTF Fun Fact 13444 – Sense of Smell Strongest at Night

by

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.
