The Origin of Language
Madeleine Beekman (Simon & Schuster)

Language remains one of the few attributes regarded as uniquely human. While animals like chimpanzees and songbirds exhibit advanced communication systems, they do not convey meaning on the same scale as humans. So, what prompted our ancestors to develop language?

Madeleine Beekman, an evolutionary biologist with a focus on insects, particularly honeybees, presents an engaging explanation in her first book aimed at general audiences regarding the evolution of human language.

Her hypothesis suggests that language emerged as a necessity to meet the challenges of parenting. In comparison to other mammals, human infants are quite helpless at birth and need around-the-clock care.

Echoing decades of paleontological research, Beekman links the vulnerable state of infants to two factors: a larger brain and a narrower pelvis. “As our bodies adapted for bipedalism, our hips narrowed,” she notes. As a result, our brains grew larger. “A big-headed baby and a mother with a narrow pelvis don’t work well together,” Beekman elaborates.

To circumvent this “obstetric dilemma,” infants are born at an earlier stage, leading to the situation where their heads are too large for a narrow birth canal. This adaptation allows for safer childbirth but necessitates extended care for the fragile young.

Thus far, the narrative is familiar. Beekman’s significant leap is to propose that the requirements of caring for human offspring spurred the development of complex languages. “Caring for human babies is incredibly challenging, leading evolution to craft entirely new tools to assist with this effort,” she asserts, “the design flaws that initiated the issue ultimately offered a solution.” While our brains made childbirth more complicated, we simultaneously developed our capacity for a richer, more flexible language.

In presenting this idea, Beekman navigates a bustling marketplace of theories on language evolution. Various hypotheses exist; some contend that language arose alongside toolmaking, where the development of advanced tools required more descriptive language for instruction. Others suggest language served as a means of social distinction, encompassing clever wordplay and insults. Additionally, it may have initially been a cognitive tool, primarily for individual thought before evolving to facilitate communication with others.

One intriguing element of Beekman’s theory is her emphasis on the roles of women and children. Science has historically leaned towards male-centered viewpoints, often overshadowing the significant evolutionary shifts linked to pregnancy (e.g., the “Hunter” model).

“
The authors contend that language is around 100,000 years old and unique to our species.
“

It’s essential to reflect on the contributions of women and children in the story of language’s origins. However, this doesn’t necessarily affirm Beekman’s thesis. She presents compelling evidence, notably showing that many large birds, including parrots and New Caledonian crows, produce underdeveloped offspring. Why? A 2023 study indicated that the primary predictor of avian brain size was the degree of parental care.

All of this resonates with Beekman’s narrative. Yet, the most pressing question remains: timing. Humans have been walking on two legs for at least 6 million years, and our brains have expanded rapidly for the last 2 million years. Given this extensive timeline, when did language actually develop?

Beekman posits that modern language is roughly 100,000 years old and specific to our species. She references 2020 research pinpointing “unique gene regulatory networks that shape the anatomy crucial for precise word production.” These networks appear to exist solely in our species, indicating that other human relatives, like Neanderthals, may not have possessed the same linguistic capabilities.

Beekman considers this “conclusive,” yet other scholars have unearthed evidence that suggests the possibility of complex language in other human species. The evolution surrounding human childbirth remains as intertwined as it is uncertain. In summary, robust ideas necessitate further proof.

Exploring ‘Silly, Fat, and Ugly’: A Personal Journey Through High School in Gaming

Posted on by

I visited the V&A Exhibition on design/play/confusion. Back in 2018, you may have experienced an intriguing set of mini-games. In this space, one could navigate a Tetris-like board to balance calories perfectly, while also battling quirky physics to nourish a character named Jenny, twisting her into a Pilates position.

Nearly seven years later, the complete version of Consume Me, which recently snagged the Grand Prize at the Independent Game Festival, is set to release this September. Developer Jenny Jiao Hsia explains that the game evolved into a semi-autobiographical narrative reflecting her high school feelings of being “silly, fat, and ugly.” What initially started as a series of mini-games focusing on Hsia’s struggles with restrictive dieting has transformed into an exploration of various aspects of her teenage life.

Hsia and co-designer Alec “AP” Thomson have been collaborating on games since their time at NYU Game Center. The idea for Consume Me emerged when Hsia shared her old diaries with Thomson, which contained her calorie charts and dieting notes. “I thought, ‘Hey, doesn’t this look like a game?'” she recalls. Thomson concurred, stating, “We started with a small prototype, and once we secured funding, the game really took off.”

The duo continued to refine their ideas, aiming to create a substantial game. “The last major project we worked on was essentially a student project,” Thomson mentions. This game was a match-3 puzzle released in 2016, and compared to that, “the entire process of Consume Me is completely different.” Hsia humorously reflects on the experience, saying, “I sat next to AP every day and was eager to guide him. With Consume Me, I had to take on more responsibility. I don’t consider myself very experienced, so it took me quite some time.”

Hsia clarifies that Consume Me was not meant as a means to address her challenges with dieting, as she left behind a phase of her life before the game’s development. Instead, she finds that crafting the narrative from her own experiences yields a richer story. “If you’re creating something from scratch without solid experiences to draw from—unless you have a strong imagination—I think it’s uninteresting,” she notes. “The character Jenny in the game isn’t solely based on me. She’s a blend of AP and me, depicting the enthusiasm for achieving goals beyond her to-do list.”

Hsia expresses her surprise that many players find Consume Me relatable and approachable. Individuals who struggle with focus might see themselves in the reading mini-games, where Jenny’s attention keeps spinning in circles with her books. Moreover, she often finds herself short on time. Additionally, Jenny’s financial woes are highlighted in a mini-game where she discovers a lucky $20 bill on the street while walking her dog, humorously dealing with its “tremendous” bowel movements. Jenny’s habit of discovering money on the streets of New York is a reflection of Hsia’s own life experiences.

“I’m curious about what people actually take away from the game,” she admits. “It’s fascinating to showcase a part of your life and let a stranger interpret it, then watch their reactions.”

Consume Me will be available for PC on September 25th.

Introverts, Extroverts, and Beyond: Exploring New Personality Types

An insightful scientist. Science News and extensive articles from expert journalists focusing on scientific, technological, health, and environmental advances.

Growing up, it was a tradition for my peers to join scouts when they turned 9 or 10. My parents gifted me a scout uniform accompanied by a matching scarf and a leather toggle to secure it at the collar.

We sat in a circle on the ground, each perched on small stools, as our leader spoke to us seriously. After discussing the essence of being a junior scout, he instructed us to pay close attention as he recited the scouting pledge, which we solemnly repeated.

It was the first moment I realized I was different; as I articulated those words, the others appeared captivated by this rite of passage. Yet, unlike them, I felt no emotional connection to the sacred bonds forged with fellow inductees or those who had come before us—just the emptiness of mere words.

Most people find it challenging to envision a state where one doesn’t feel a deep-seated affinity or loyalty to any group. This experience is rare; some consider such psychological tendencies as disorders to be addressed. However, over my 40 years as a clinical psychiatrist, I’ve come to understand that many of my patients (and I) being indifferent to group memberships isn’t necessarily a psychological issue.

Otroverts is a term embraced by individuals who don’t feel bound to merge their identities with others. We all begin life as otroverts until childhood cultural influences solidify our attachments to various identities and groups.

The struggle to identify with a group can lead to social implications in cultures structured around participation. However, being outside these groups can have its advantages: free from implicit rules and influences of belonging, unoften brings originality and emotional autonomy.

By being on the outside, you’re free to think and create unfettered. GroupThink loses its hold, allowing you to discern your thoughts from the collective’s gravitational pull, enabling you to explore ideas without the fear of undermining the group’s notion of what constitutes a “good” idea.

Since you can’t be expelled from a group you aren’t part of, fears of social rejection diminish. There’s no need for external validation or relying on others for emotional support; you don’t feel compelled to prove your worth to anyone.

Our society often blurs the line between connection and belonging. Yet it’s essential to recognize that those who find it challenging to connect may struggle to foster a sense of belonging, but that doesn’t mean they lack connection entirely. In reality, free from the distractions of pop culture, cliques, family disputes, and political factions (all of which relate to otroverts), one can truly bond with those who resonate on a deeper level.

History showcases many independent thinkers who maintain emotional detachment from any group, allowing them to recognize the fanaticism of groupthink long before deviating into it. Orwell is a notable example.

Sadly, it appears that individuals often need to rise from the ashes of destructive group dynamics before they can grasp their rightful path as independent thinkers.

We might learn from the otrovert perspective that while community has its merits, we must remain acutely aware of its darker tribal undercurrents.

Denisovans: Exploring Why Mysterious Ancient Groups Lack Species Names

Posted on by

This excerpt is from our human stories newsletter, focused on the archaeological revolution—sign up to receive it monthly.

In human stories, I aim to address common questions about human evolution. In February 2021, I tackled a query that many find perplexing—whether Neanderthals and modern humans are distinct species (short answer: species boundaries are ambiguous).

This month, we confront another frequently asked question: Do Denisovans, the extinct human group once prevalent in Asia, have a designated species name? If so, what should that name be?

The debate regarding the “official” name of the Denisovans has been lively since their discovery in 2010. Notably, in June, the skull of Harbin, dubbed the Dragon Man from northern China, was classified as Denisovan through molecular evidence. This marked the first acquisition of a Denisovan skull, giving us insights into their facial features.

While participating in New Scientist discussions, host Rowan Hooper asked why Denisovans lack a species name. Why can’t we refer to them as Homo Denisovanensis, similar to how Neanderthals are called Homo Neanderthalensis?

I preferred a straightforward explanation: insufficient information has hindered a definitive classification of Denisovans. Their DNA shows significant divergence from Neanderthal DNA; yet, we require detailed insights into their anatomy and skeletal structure.

However, this inquiry is multifaceted. First, we must identify which fossils unequivocally belong to Denisovans. This involves analyzing numerous specimens and decades of research, complicating the resolution. Secondly, we need to determine which of the assigned names should take precedence under our classification norms—a legal question that adds to the complexity.

Who’s Included and Who’s Excluded?

A brief reminder about Denisovans: they are an enigmatic group of humans initially identified in 2010 from fragments of a finger bone discovered in the Denisova Cave in Siberia’s Altai Mountains. Genetic analysis revealed they were distinct from both modern humans and Neanderthals. Moreover, many contemporary individuals, especially in Southeast Asia and Melanesia, carry Denisovan DNA.

This suggests that Denisovans were quite widespread in East Asia over the past several hundred thousand years. So, where are the Denisovan fossils?

Fifteen years later, a handful of Denisovan fossils have been actively categorized. For example, mandibles discovered on the Tibetan Plateau were identified through fossil proteins and sediment DNA. Similarly, a jawbone retrieved from the Pengle waterway off the coast of Taiwan was confirmed as Denisovan in April.

Nonetheless, we still lack a complete skeleton. Identifying the Harbin skull as Denisovan brought us closer to understanding their appearance, yet many more discoveries are necessary.

Numerous human fossils in East Asia potentially belong to Denisovans. However, categorizing these remains has proven challenging, as they often do not resemble established species like modern humans, Neanderthals, or even Homo Erectus. If adequate specimens surface, thus confirming their Denisovan identity, our understanding could significantly improve, leading to a formal classification.

But how do we determine which fossils are Denisovan? Ideally, we seek molecular evidence of preserved DNA or protein for comparison with the original Denisovan remnants. However, many fossils remain unanalyzed or inaccessible.

One notable effort to address this issue was a preliminary study submitted by a team led by Xijun Ni from the Chinese Academy of Sciences in March 2024. By comparing 57 human fossils for various physical traits, they constructed familial relationships between these findings.

The team found three primary groups among Eurasian hominins: Modern Humans, Neanderthals, and a third group composed of the original Denisovan fossil, the Tibetan cave jawbone, the Pengle jawbone, and the Harbin skull. This third category appears to represent those we refer to as Denisovans.

This is an intriguing proposition, but others disagree.

A collection of contentious fossils from Hualongdong, southern China, offers a wealth of material: an almost complete skull, 14 teeth, an upper jaw, six isolated teeth, and additional fragments dating back around 300,000 years.

While the NI team classified the Hualongdong specimens as part of the Denisovan group, a study led by Xiujie Wu in July suggested that these teeth did not show clear correlations, proposing instead that they may belong to a different hominin group. Another interpretation could be that the Denisovans at Hualongdong were somewhat disparate from those in other regions.

In the meantime, other intriguing fossils from Asia continue to emerge. Among them are specimens from Dariscal and Jinniushan, both around 260,000 years old, which Ni’s team has suggested might also belong to the Denisovan lineage.

As the list of contending Denisovan fossils grows, we must decide how to categorize them.

The Harbin Skull

Hebei Geo University

Homo — What Does It Mean?

Interestingly, I was part of the team that described the Harbin skull in 2021, and we named it Homo Longhi. So, could that be the name we assign to Denisovans?

However, last year a competing proposition was put forth by Woo and Christopher Beh from the University of Hawaii, who suggested that we should center around fossils from Xujiayao in northern China, proposing to call this new species Homo Jurensis—fossils that would include the original Denisovan findings.

This idea’s strength lies in the resemblance of Xujiayao fossils to Denisovan remains, a point also observed by the NI team. However, Bae and Wu aimed to designate the Xujiayao fossils as “type specimens.”

This raises two issues: the classification of fossils and the naming protocols. Let’s examine each aspect separately.

In classification, the Homo Jurensis proposal faces challenges. Bae and Wu classify the Harbin skull as Homo Jurensis or Denisovan, yet it lacks sufficient resemblance to warrant such designation. A study published in June demonstrated molecular evidence clearly linking the Harbin skull to Denisovans. Hence, identifying those fossils as Denisovan would contravene objective realities, making Homo Jurensis seem unfounded.

What about taxonomy? This area is intricate. A crucial factor is the concept of priority, where the first proposed name tends to gain precedence. Hence, Homo Longhi might likely take precedence over Homo Jurensis as it was suggested three years earlier.

Are there alternative names for Denisovans?

The excavators of Denisova Cave never formally classified Denisovans as a distinct species. Anatoly Derebianco, part of that team, suggested the name Homo Sapiens Altaiensis, implying they would serve as a modern human subspecies—yet this proposal lacked formal status, rendering it typically insignificant.

This year, Derebianco has published a series of papers discussing what Denisovans could be. His references include locations in Mongolia, Uzbekistan, Tajikistan, and Iran, referring to them collectively as Homo sapiens denisovan. I remain unsure if formal explanations were provided, as only abstracts were published, and if completed, it occurred post the naming of Homo Longhi.

In deeper investigations, a few additional designations emerge. A 2015 study proposed Homo Denisovensis, while a 2018 paper considered Homo Denissys. Neither is widely accepted.

Lastly, it’s possible that one of the names was assigned to an Asian human fossil within an obscure publication decades ago. If the fossil is ultimately identified as Denisovan, the name takes precedence (assuming it was adequately introduced). Nevertheless, Wu, Bae, Ni, and others assessed this notion in 2023 and concluded that many crucial fossils were not appropriately named. For instance, there was a suggestion to label Dali’s skull as Homo Dariensis, yet such ideas amounted to informal statements rather than formally recognized classifications.

Your head might be swirling from this cascade of names and species classifications, so let’s recap: the critical takeaway is our evolving understanding of Denisovans, which brings us closer to officially designating their name.

Given our comprehension of taxonomic norms and their significance, Homo Longhi could emerge as the official designation. Although I can’t influence the decision, they will always remain Denisovans in my mind.

AI Slop: The Soap Opera of Space-Trapped Kittens Set to Conquer YouTube

Posted on by

Welcome to YouTube in the era of AI-generated videos: featuring a baby stranded in space, a zombie football star, and a cat drama set among the stars.

Currently, one in ten of the fastest-growing YouTube channels globally is dedicated entirely to AI-generated content, highlighting advances in technology that have led to an influx of artificial media.

According to an analysis by the Guardian, which utilized data from analytics firms like Playboard, nine of the top 100 fastest-growing channels this July featured solely AI-generated content.

These channels offer bizarre narratives, such as babies aboard pre-launch rockets, an undead Cristiano Ronaldo, and melodramas starring anthropomorphized cats. The surge in AI video creation is propelled by powerful new tools like Google’s VEO 3 and Elon Musk’s Grok Imagine.

One channel has garnered 1.6 million views and 3.9 million subscribers, called Space Chain, while the Super Cat League features a human-like cat in surreal scenarios, including a scene where it confronts an eagle.

Many of these videos are labeled “AI Slop,” indicating their low quality and mass production. Despite this, some offer a rudimentary plot, signaling advances in the sophistication of AI-generated content.

YouTube has attempted to manage this influx of low-quality AI content by implementing a policy to block advertising revenue sharing from channels that primarily post repetitive or “fraudulent” content.

A YouTube spokesperson emphasized that all uploaded content must adhere to Community Guidelines.

After the Guardian inquired about certain channels from June’s fastest-growing list, YouTube confirmed the removal of three such channels and the blocking of two others, though they did not disclose specifics.

Experts indicate that AI-generated videos signal a new phase of internet “Enshittification,” a term coined by Doctorow in 2022 to describe the decline in online user experiences as platforms prioritize their own gains over quality content delivery.

“AI Slop is flooding the platform with content that is essentially worthless,” noted Dr. Akhil Bhardwaj, an associate professor at Bath University. “This enshittification has damaged the quality of the Pinterest community and overwhelmed YouTube with subpar content aimed solely at revenue generation.”

“One way social media companies could regulate AI Slop is by ensuring it remains unmonetizable.”

Ryan Broderick, who writes the popular Garbage Day Newsletter on internet culture, described YouTube last week as a “dumping ground for AI shorts utterly devoid of substance.”

Other platforms like Instagram also showcase a plethora of AI-generated content. For instance, one popular video features a blend of celebrity heads and animal bodies, such as “rophant” (Dwayne Johnson paired with an elephant) and “Emira” (Eminem as a gorilla), attracting 3.7 million views here.

On TikTok, numerous AI-generated videos are going viral, including one titled “Abraham Lincoln Blogging”, showcasing his unfortunate trip to the opera, and another with cats in Olympic diving events. These videos capture the playful, quirky spirit characteristic of the internet.

Instagram and TikTok have announced that all realistic AI content should be labeled. Videos suspected of being AI-generated from these platforms are cross-verified with the DeepFake Detection Service provider Real Defender.

Here are the channels showcasing AI videos for July:

Exploring Black Holes with Interstellar Nanocrafts: A Guide

Posted on by
Reply

Conceptual image of a spacecraft navigating near a black hole

An interstellar spacecraft designed to explore a black hole could transmit data back to Earth in roughly 100 years.

Cosimo Bambi from the University of Hudang in Shanghai has devised a framework for such missions utilizing technologies projected to be available within the next 20 to 30 years.

By approaching a black hole, we can validate Albert Einstein’s theory of general relativity and uncover the behavior of fundamental physical constants in extreme gravitational fields.

The nearest well-known black hole is approximately 1500 light years away. However, within our Milky Way galaxy, there is estimated to be one black hole for every 100 ordinary stars. This suggests a significant likelihood of locating a black hole within 20 to 25 light years, says Bambi.

Identifying a black hole poses challenges, as these entities do not emit light; astronomers must infer their existence by observing their gravitational influence on surrounding stars.

Reaching a black hole within 25 light years of our solar system will require advanced technological developments, but according to Bambi, “it’s achievable.” Within a century, spacecraft could be minuscule, featuring sails that cover 10 square meters and propelled by light. Such crafts could theoretically accelerate to about one-third the speed of light through pulses from high-powered lasers.

“Currently, light sails and nanocrafts appear to be the most viable options for interstellar travel since they can achieve speeds approaching that of light,” Bambi states. However, he estimates that the power required for an effective laser system could reach approximately 1 trillion euros today.

To validate predictions concerning general relativity, it may be necessary to dispatch two miniature spacecraft or release a secondary probe as the primary nanocraft nears a black hole. The secondary craft would venture closer to the black hole, while the primary craft remains at a safe distance, gathering data and relaying it back to Earth.

Gerlan Lewis from the University of Sydney acknowledges that while the challenges are significant, the proposal is far from impossible.

However, the extensive time frame for the proposed mission introduces a possibility that nanocrafts could become outdated by the time they reach their destination. Lewis remarks, “Considering 100 years of technological advancement, can we truly predict what kind of propulsion system might exist then?”

“A mission to black holes would likely resemble this proposal, akin to how we might imagine the advancements of the 20th century, 500 years in the past,” he adds.

Lewis points out that Bambi’s plans do not address how to decelerate the nanocrafts upon arrival at the black hole. Bambi suggests that the simplest approach is to not slow the vehicle at all, but rather deploy a probe to transmit data back to the main craft for Earth delivery.

“In such scenarios, the probes won’t stop around the black hole; they will merely pass by. Some may be drawn into the black hole, which should provide sufficient data to analyze the black hole’s gravitational field,” he explains.

Sam Baron at the University of Melbourne describes Bambi’s framework as one of the most “speculative” research papers he has encountered, but notes that a century ago, the construction of the Large Hadron Collider would have seemed like science fiction.

“I believe utilizing small-scale technologies is likely the way forward,” he observes. “The question remains whether we can indeed engineer something that meets all the criteria outlined in this paper.”

Bambi emphasizes that human beings cannot personally venture to black holes due to the extreme accelerative forces—around 10,000 g—that nanocraft would need to endure. “Unless we discover a wormhole in the fabric of space-time to provide a shortcut,” he notes.

“We really need a nearby wormhole like in the movie Interstellar” to facilitate human missions,” he concludes. “Unfortunately, my assessment is that wormholes are purely theoretical at this point.”

Mark Twain famously remarked, “If you were born at the age of 80 and gradually refined down to 18, life would be perpetually joyous.” The quest for youth has captivated stories and myths throughout the ages; what if we could finally achieve it?

Recent research indicates that the GLP-1 medication Ozempic, containing semaglutide, might effectively reverse biological aging by around three years. This effect is notably observed in the brain, suggesting that medications like Ozempic could help mitigate conditions such as dementia. Additionally, it seems to reduce inflammation tied to various health concerns, including heart disease, chronic pain, and depression.

Originally developed for type 2 diabetes, semaglutide has changed the landscape of obesity treatment. It’s important to highlight that its anti-aging effects are particularly noted in individuals with HIV-related fat hypertrophy, though researchers believe its benefits may extend to a broader population.

Ozempic seems to have eradicated the inflammatory system associated with numerous health conditions.

It’s intriguing to consider whether we should all be using these drugs to reverse aging and reap the rewards of better health. However, we cannot assume this is wise without substantial evidence from large placebo-controlled trials involving healthy individuals. Conducting such studies may be contentious, as there are potential side effects to monitor. Moreover, when supplies are limited, it’s crucial to prioritize those in dire need.

Nevertheless, it appears that a number of healthy individuals are already utilizing these medications—largely “off-label”—without clarity on their safety. Future research should unveil a clearer understanding of these risks and provide insights into how weight loss affects muscle mass retention.

As the array of health advantages associated with these drugs continues to expand, it may be time to investigate their efficacy in healthy individuals, aiming to determine if they genuinely have the capacity to slow aging rather than speculating about youthful elixirs.

Exploring How Homona Lady’s Burial Practices Redefine Humanity

Posted on by
Reply

From an early age, the inevitability and finality of death profoundly shape our lives. Our capacity to comprehend the sorrow of our eventual end, as well as the loss of connection, is a fundamental aspect of what it means to be human. These understandings have fostered iconic rituals that are deeply embedded in human culture.

Historically, we have presumed that Homo sapiens is the only human species aware of the mortality inherent in living beings. However, as detailed in “What Ancient Humans Thought When They Began Burying the Dead,” archaeologists are challenging the notion that a significant emotional response to death is uniquely ours.

A particularly provocative assertion is that ancient humans, vastly different from us, established the death ritual. But evidence points to Homo naledi, an ancient human from southern Africa, whose brain was only one-third the size of ours and who lived at least 245,000 years ago. It remains unclear what drove these early humans to develop a culture surrounding death; one intriguing, though speculative, theory posits they did so to help younger members of their community cope with the loss of others.

Many controversies surround claims regarding H. naledi and their burial practices, primarily concerning the evidence’s quality. Nevertheless, since the mid-20th century, researchers have worked to bridge the behavioral gap between our species and others, propelled by studies revealing that many animals lead emotionally complex lives. Some even create their own rituals when encountering death within their communities. This adds weight to the argument that our ancestors may have developed their own cultural practices surrounding death as far back as 500,000 years ago, suggesting that H. naledi might also have established a burial tradition.

Archaeologists question whether a profound response to death is exclusively our domain.

A striking reflection of melancholy regarding H. naledi suggests that they may have aided the younger generation in confronting the weight of loss. This consideration brings into question our understanding of what it means to be human, and whether our ancestors were as unique as we assume in processing the concept of loss.

Exploring the 11 Types of Obesity and Their Distinct Causes

Posted on by
Reply

We might finally grasp why weight loss methods, such as exercise, often don’t succeed for all individuals with obesity

Science Photo Library/Alamy

Understanding obesity is proving to be more complex than previously recognized, with various types potentially stemming from different biological mechanisms.

“It transcends just body mass index and physical appearance; it delves into the biology driving it and its connection to health risks,” says Akl Fahed from the Broad Institute in Cambridge, Massachusetts.

The World Health Organization defines obesity as accumulating fat that poses a health threat. Determining if someone is obese involves calculating their Body Mass Index (BMI), which compares weight to height.

Since not all individuals with obesity experience health issues, some researchers have recently suggested introducing a “preclinical” obesity category. This approach separates individuals with medical complications related to excess fat, such as breathing difficulties or heart conditions, from those who currently show no symptoms but may develop them in the future. Yet, according to research by Fahed and his team, these classifications are still evolving.

The scientists executed genome-wide association studies involving over 2 million obese individuals, seeking connections between genetics and metrics such as BMI, waist circumference, waist-to-hip ratios, and hip circumference across diverse ancestry. They identified 743 genetic regions linked to obesity, with 86 of them being novel discoveries.

Subsequently, researchers investigated which tissues showed obesity-related effects from genetic alterations in these regions, focusing on processes like insulin production, the hormone that regulates blood sugar levels. They found that these genes fall into 11 distinct clusters, each linked to a unique biological pathway.

The pathways include: metabolically unhealthy obesity, metabolically healthy obesity, and six types associated with insulin secretion, immune system regulation, appetite control, body weight management, and lipid metabolism.

The team designates these clusters as “endotypes” rather than “subtypes” to highlight that while subtypes are typically mutually exclusive, endotypes reflect identifiable biological mechanisms that can coexist in individuals with varying impacts.

Using data from over 48,000 individuals, the researchers validated their endotypes through the Mass General Brigham Biobank.

“Clearly, there are numerous forms of obesity,” states Frank Greenway of Louisiana State University in Baton Rouge. Some obese individuals may not lose weight even with GLP-1 medications like Ozempic or Wegovy.

Gaining a deeper understanding of obesity and its various forms might refine our approach to treatment. “Recognizing the diverse types of obesity may lead to more targeted interventions and personalized care,” says Laura Gray from the University of Sheffield, UK.

Six of the 11 endotypes relate to insulin regulation, suggesting that some interventions might be effective across multiple clusters, according to team member Min Seo Kim at the Broad Institute.

The findings could reshape our understanding of research exploring the interplay of genetics and lifestyle in obesity, traditionally regarded as a singular condition, potentially influencing future research methodologies, Kim remarks.

Gray suggests that there may exist more than 11 endotypes. This figure was constrained by the genetic regions currently known to affect obesity, she notes. Kim shares this sentiment, expressing the likelihood of discovering additional endotypes as genetic research progresses.

Conversely, Henriet Kirchner from the University of Lübeck in Germany believes there could be fewer than 11 endotypes. She emphasizes the need for further replication of these findings in the scientific community to enhance understanding. “The concept of obesity clusters is appealing, but it must be refined in the future to be beneficial in clinical settings,” she states.

Initially, videos of this genre—a retelling of biblical tales through the lens of Americanized video blog culture—may seem bizarre and sacrilegious. However, might they represent a unique synthesis of the Holy Trinity of 2025: AI, influencer culture, and rising conservatism? Are these videos indicative of our era? Do they reflect the concerns of American conservatism? Am I being subtly influenced towards Christianity? Why do these Biblical inspirations feel oddly alluring? Why can’t I look away? What’s happening to my brain?!

My first encounter with these biblical video blogs was while I lounged in bed. When the algorithm unveiled Joseph of Nazareth, I momentarily halted my endless scrolling. “Whoa, look at that fit! Ancient rock vibes.” I wiped the drool from my chin and took a moment. Although mindlessly scrolling may not usually be a cure for mental fatigue, that day, I felt like Daniel in the lion’s den or Jonah in the whale. My commitment to scrolling brought me a sense of salvation.

In my younger days, I flirted with religion. When my grandparents visited, I would kneel in prayer, attend Bible studies, and socialize with youth groups to meet friends and boys. I had a brief infatuation with Hillsong (I was 13 and just wanted to plan for a Friday night). a) The girl before me screamed, “I’ve been captured by the devil.” And b) I sneaked behind the church curtains to find the teenagers locked in each other’s glances.

My attitudes towards both faithfulness and spirituality have transformed. Now, my spiritual routine consists of exclamations like, “Jesus take the wheel!” or “What a deity!” as I snap photos of church art while traversing Catholic nations, sharing through Instagram later on.

Yet, every night, I find myself scrolling past clothing and dining suggestions while immersing myself in the cultures that birthed them. Vibrator check from last night’s gathering. Then I slide into a video blog Unboxing Trojan horses. Or perhaps a Vox Pop from Easter Monday. Followed by a series of street reactions David defeats Goliath. Something totally fascinating.

Recently, I came clean to a friend about my obsession. I was evangelizing to a fellow enthusiast. She mentioned that Jesus resembled the first influencer and that Mary and Joseph embodied the archetypal toxic vlog parents. If Judas were alive today, he would upload lengthy unedited rants on YouTube.

Momentarily, I ponder the environmental ramifications. How much water was used for Mary’s perfect dab? What resources were consumed so AI Jesus could jokingly narrate a tutorial on wine making? And how long have we been off-planet? Hold on! Shhh, the next video starts.

Adam is now seated in a podcast studio, headphones on, microphone positioned, dressed informally with leaf-patterned fabric. “So, God creates me? Boom. The first man, the parents, nothing. I… ‘Ah… I’m literally going to be everyone’s dad! When they split up, I’ll ensure they clash endlessly. Another! Another! Another! Another!”
