Hunter-gatherer Societies May Be More Hierarchical Than They Seem

The Tsimané people of Bolivia believe that humility signifies a worthy person.

This metaphor is so overused that it has become a cliché. Hunter-gatherers share their resources equally among their tribes, demonstrating a noble generosity that is often absent in wealthier societies. However, a review of anthropological evidence suggests a more nuanced reality.

“No society exemplifies true equality,” asserts Chris von Ruden, an anthropologist at the University of Richmond in Virginia. What may seem like equality is instead a product of practical or even selfish behaviors.

Some researchers, observing the apparently equitable distribution of resources in traditional subsistence societies, have posited that humans inherently lean towards altruism and equality. For instance, 19th-century philosopher Friedrich Engels, a close associate of Karl Marx and a staunch advocate of Marxism, drew inspiration from reports highlighting the egalitarian nature of traditional cultures.

“Yet, it’s not merely about sharing everything with everyone,” notes von Ruden.

After analyzing the existing data, von Ruden and his colleagues, including Duncan Stebbard Hawkes from Durham University in the UK, contend that some anthropologists mistakenly interpret community wealth equality as an indication of a shared desire for equality. They argue that the pursuit of equality in some traditional societies may stem more from individuals’ desires to avoid constraints on their choices. For instance, the Mbenjele community in the Republic of Congo has a grievance mechanism called mosambo, where individuals vocalize to the entire camp about their perceived rights violations.

“People dislike bullying, coercion, and those who dominate,” remarks Manvir Singh, an anthropologist at UC Davis not involved in the study. He believes that von Ruden and Stebbard-Hawkes accurately highlight that societies focused on individual autonomy may appear egalitarian.

Researchers have observed that along with a desire for autonomy, equality can also emerge from self-serving actions. Instead of altruistically sharing hunting successes, hunters might distribute meat to avoid continued blame. Von Ruden and Stebbard-Hawkes cite evidence of frequent and vocal demands for food sharing among hunters in various foraging cultures. For example, it has been noted that over 34% of daytime conversations among the !Kung people, who inhabit regions in Angola, Botswana, and Namibia, involve complaints about others being stingy.

Additionally, a society characterized by individuals willing to share resources and assist each other isn’t necessarily devoid of social hierarchies. Certain cultures reward those who are more cooperative and community-focused. For example, the Tsimané people of Bolivia hold that humility and kindness are essential traits of worthy individuals. Thus, von Ruden and Stebbard-Hawkes suggest that the equality observed in traditional societies could result from intense competition to be viewed as the fairest among peers.

The study represents “a significant contribution that compiles various ethnographic cases to illustrate the diversity and complexity of egalitarianism,” notes Jerome Lewis, an anthropologist at University College London. He asserts that the 19th-century portrayal of Engels as a “noble savage” residing in an idyllic, principled society is outdated and represents a “very discriminatory and biased perspective.” Just like other human groups, hunter-gatherers compete, argue, and seek resolution for their conflicts.

Lewis emphasizes that traditional subsistence societies worldwide have created “impressive alternatives” to the ways high-income nations structure culture and justice. Some of these societies have thrived for over 50,000 years, offering valuable lessons and fresh perspectives on how we might organize ourselves.

Tesla Launches Affordable Model 3 in Europe Amid Criticism of Mask Sales

Tesla has introduced a more affordable version of its Model 3 in Europe, aiming to boost sales amid concerns over Elon Musk’s partnership with Donald Trump and a decline in electric car demand.

Musk, the CEO of the electric vehicle manufacturer, believes that this lower-priced variant, which was rolled out in the US last October, will stimulate demand by appealing to a broader audience.

The new Model 3 Standard is priced at €37,970 (£33,166), NOK 330,056 (£24,473), and SEK 449,990 (£35,859) in Germany. This release comes after Tesla’s successful launch of the affordable Model Y SUV in both Europe and the United States.

While the more affordable Model 3 and Model Y versions forgo some luxury finishes and features found in pricier models, they still provide over 300 miles (480 km) of range.

Tesla’s sales have decreased in Europe as it contends with growing competition from Chinese rival BYD, which became the first company in the area to outpace the U.S. electric car maker earlier this spring.

Additionally, buyer backlash against Musk’s support for Trump’s political endeavors has adversely affected sales across the EU.

Musk, who implemented significant layoffs while leading the Office of Government Efficiency, stepped down in May following disagreements with President Trump regarding the “big, beautiful” tax and spending legislation.

Furthermore, Musk has distanced potential clients through various controversial political actions, including a Nazi salute at Trump’s victory rally, endorsing Germany’s far-right AfD party, and accusing Keir Starmer and other prominent British politicians of concealing scandals related to gang raids.

Critics warn that a new tax on electric vehicles introduced in last month’s Budget could dampen demand in the UK. According to the Society of Motor Manufacturers and Traders (SMMT), UK electric vehicle sales rose by only 3.6% in November, marking the slowest growth in two years.

Mike Hawes, CEO of SMMT, stated: “[This] sustained increase in demand for EVs should be regarded as a wake-up call that we cannot take this for granted. Instead of penalizing drivers, we must seize every chance to motivate them to transition to electric vehicles.”

The Chancellor’s forthcoming pay-per-mile road tax for EVs will impose a charge of 3p per mile starting in April 2028, resulting in an average annual cost of about £250 for drivers.

Tattoos May Impact Local Immune System Function

Some researchers are concerned that tattoos might be hazardous to health

Research indicates that tattoo ink can accumulate in lymph nodes, potentially disrupting the immune system and leading to permanent alterations in the body’s disease defense mechanisms.

This conclusion arises from a study involving mice, which revealed chronic inflammation in the lymph nodes of tattooed animals—nodes that were stained with ink—and modified antibody responses to vaccinations. Similarly, studies have shown inflammation and discoloration in the lymph nodes of individuals with tattoos, persisting for years after the tattoo was applied.

The findings suggest that tattoos could increase disease risk and highlight the necessity for further investigation. Santiago González from the University of Lugano, Switzerland, asserts, “When you get a tattoo, you are essentially injecting ink into your body. This affects not only the skin’s appearance but also the immune system. Chronic inflammation, over time, can deplete the immune system, increasing susceptibility to infections and certain cancers—many questions remain that require additional research.”

Tattoos are becoming increasingly popular worldwide, with approximately 30 to 40 percent of individuals in Europe and the United States sporting at least one tattoo. Though Gonzalez does not have a tattoo, he admires them as an art form, stating, “I think they’re visually appealing.” Nonetheless, the long-term health implications of tattooing—particularly concerning the immune system—are still not well understood.

Gonzalez noted that he and his team were conducting an unrelated investigation into inflammation in mice when they observed a “crazy inflammatory response” after applying small identifying tattoos. Curious, they decided to delve deeper.

The team utilized standard commercial inks in black, red, and green to mark 25 square millimeter patches on the hind legs of several mice. With specialized imaging technologies, they tracked the ink traveling through lymph vessels towards nearby lymph nodes almost immediately, often within minutes.

In these nodes, the researchers found that macrophages (immune cells that eliminate debris, pathogens, and dead cells) absorbed the ink, turned the nodes discolored, and initiated acute inflammation. Within approximately 24 hours, these macrophages would perish and release the ink, which would then be taken up by other macrophages, creating a continuous cycle of chronic inflammation that outlasted the healing of the tattoo site.

After two months, during which the tattoos remained, the mice still exhibited inflammatory markers in their lymph nodes that were up to five times higher than typical, Gonzalez reported.

To comprehend how this inflammation affected immune functioning, the researchers administered a vaccine directly into the tattooed skin. Notably, the tattooed mice demonstrated a markedly weaker antibody response to the COVID-19 mRNA vaccine compared to control mice, while showing a stronger response to the influenza vaccine.

Further analysis revealed that the lymph node macrophages from tattooed mice were filled with ink and struggled to capture the COVID-19 vaccine. For mRNA vaccines to be effective, they must be processed by macrophages. Conversely, the protein-based influenza vaccines triggered an enhanced antibody response, likely due to an increase in immune cells drawn to the tattoo site. “The response may vary based on the type of vaccine,” Gonzalez explained.

Lastly, the researchers investigated a limited number of lymph node biopsies from individuals who had tattoos near their lymph nodes. Two years post-tattoo application, the lymph nodes retained visible pigment, housed within the same type of macrophages observed in the mouse research. “Their lymph nodes were entirely filled with ink,” noted Gonzalez.

Crucially, he emphasized that even if individuals undergo tattoo removal, the ink is likely to persist in the lymph nodes for a lifetime. “You can eliminate ink from your skin, but the ink in your lymph nodes remains,” he stated.

The research findings illuminate the long-suspected link between tattoos and immune response. Christel Nielsen at Lund University, Sweden, indicated that her team had recently published findings that suggest individuals with tattoos have a heightened melanoma risk. She believes that the findings from Gonzalez’s team may be explained by increased inflammation in lymph nodes. “This study provides compelling proof that this is indeed the case,” she remarked, calling it a significant advancement in our understanding of the relationship between tattoos and disease.

For Michael Jurbdazian, this study conducted at the German Federal Institute for Risk Assessment in Berlin paints a clearer picture of how tattoo pigments interact with the immune system. However, he notes that results from mouse studies might not precisely mirror human outcomes, especially considering the differences between human and mouse skin. “The correlation with human health, particularly once healing is complete, necessitates more investigation,” he stated.

Horror Game Horses Banned: Is the Controversy Bigger Than You Think?


On November 25th, Santa Ragione, the celebrated Italian developer known for acclaimed titles like MirrorMoon EP and Saturnalia, will
unveil their latest project “Horses”, which faced a ban from Steam, the largest digital marketplace for PC games. Shortly after, Epic Games Store also pulled the game just days before its intended release on December 2. Additionally, Horses was briefly removed from the Humble Store, though it was reinstated the following day.

This stirred-up controversy thrust the game into the spotlight on various digital platforms.
Teeth sells it on itch.io and GOG. Nevertheless, the pivotal question lingers—why was it banned? Horses tackles various highly sensitive subjects (the introduction notably warns of “physical violence, psychological abuse, graphic brutality, depictions of slavery, physical and psychological torture, domestic abuse, sexual assault, suicide, misogyny”), making it both disturbing and unsettling.




Controversial…horses. Photo: Santa Ragione

The storyline is straightforward but soon takes a dark turn. You step into the shoes of Anselmo, a 20-year-old Italian man who is sent to spend his summer on a farm for personal development. It rapidly becomes clear (so much so that I let out a startled “ha!”) that this is no ordinary farm. The “horses” present there are not real horses but naked humans with horse heads seemingly affixed to them.

Your task is to tend to the garden, the “horses,” and the “dog” (a human with a dog’s head). Throughout Horses’ three-hour duration, Anselmo engages in tedious and painfully slow daily chores, such as chopping wood and gathering vegetables. However, these mundane activities are peppered with disturbing tasks. On the first day, you stumble upon the corpse of a “horse” hanging from a tree and must assist the farmer in burying it.

While undeniably unsettling, Horses provides little in terms of horror nuance, and when it does, the severity is lessened by basic, crude graphics (when a farmer lashes a human horse and subsequently applies hydrogen peroxide to its back, the resulting marks on its skin appear blurred and unrealistic).




Anxiety…horses. Photo: Santa Ragione

The genitals and udders of the “horses” are obscured. Slaves are prohibited from fornicating, yet we observe they still partake in such acts (depicted in a simplistic and animalistic manner). You are compelled to “tame” them by returning them to their pen, but your interactions with them are limited to button presses, leaving what you’ve done to them ambiguous.

Valve, the owner of Steam,
informed PC Gamer that Horses underwent content review in 2023. “After our team played the build and reviewed the content, we provided feedback to the developer regarding why the game cannot be published on Steam in accordance with our onboarding rules and guidelines,” reads their statement. “After some time, the developer requested we reassess the review, leading our internal content review team to discuss it thoroughly and communicate our final decision to the developer not to publish the game on Steam.”

According to IGN, the Epic Games Store told Santa Ragione, “Upon investigation, we found violations of the Epic Games Store Content Guidelines, specifically in our ‘Inappropriate Content’ and ‘Hateful or Abusive Content’ policies, and as a result, the game cannot be published on the Epic Games Store.” Santa Ragione asserts that “the specifics of the contested content have not been clarified.”

The gameplay in Horses is grotesque but not without purpose. The horror is psychological, rooted in the unsettling sensation of performing mundane tasks in a hellish environment without understanding the reasons behind such bizarre occurrences. There’s minimal sound beyond the constant whir of a film camera (the game presents itself akin to a nearly silent Italian arthouse film), with sporadic cuts to ultra-close shots of mouths talking and chewing, disconcerting character models, and real-world visuals of water being poured into glasses or slop filling a dog’s bowl.

While there’s no explicit gore or overt violence, the discomfort, annoyance, and unease pervade throughout, exposing primal human fears without severely disturbing your lunch. Though this serves as an intriguing reflection on violence and power dynamics, it does not embody a shocking or excessive experience. The discussions it has sparked about video games as an art form and the censorship of art ultimately seem more profound than the game’s actual content.

Comet 3I/ATLAS from Beyond the Solar System Contains Essential Life-Creating Molecules

Comet 3I/ATLAS is the third known visitor from beyond our solar system

The interstellar comet 3I/ATLAS releases carbon-rich compounds at a higher rate than most comets in the solar system, including methanol. This compound plays a crucial role in prebiotic chemistry and is not commonly found in other interstellar objects.

Having made only three known visits to our solar system, 3I/ATLAS stands apart from comets found in our galactic neighborhood. While approaching the Sun, it developed a crust of water vapor and gas, containing significantly more carbon dioxide than typically found in Solar System comets. Additionally, the comet’s light appeared unusually red, hinting at atypical surface chemistry, and it began emitting gas well before reaching the Sun. This could indicate that it has not approached another star in hundreds of millions of years, or possibly since leaving its home system.

Recently, Martin Cordiner and a team using the Atacama Large Millimeter/Submillimeter Array (ALMA) in Chile discovered that 3I/ATLAS generates significant amounts of hydrogen cyanide gas, as well as even larger quantities of gaseous methanol. “Hydrogen cyanide and methanol are usually found in trace amounts and aren’t dominant components in our comets,” explained Cordiner. “However, they appear to be notably abundant in this alien comet.”

Cordiner’s research team observed that the hydrogen cyanide comes from near the comet’s core, producing around a quarter to half a kilogram per second. Methanol was also found in the core, indicating large quantities are produced even within the comet’s coma, which is the extensive trail of dust and gas extending miles away from the comet itself.

Methanol is emitted at approximately 40 kilograms per second, significantly more than hydrogen cyanide, which represents about 8 percent of the total vapor released (compared to roughly 2 percent from typical solar system comets). The different locations of these two molecules suggest that the comet’s core may not be uniform, which could provide insights into how comets are formed, according to Cordiner.

Cordiner noted that, while methanol is a relatively straightforward carbon-based compound, it plays an essential role in forming more complex molecules critical for life. Its production appears to be high when chemical reactions producing these larger molecules occur. “Chemically, it seems unlikely that we can progress toward highly complex substances without generating methanol,” Cordiner said.

Josep Trigo-Rodriguez and colleagues from Spain’s Institute of Space Sciences suggested that comets with substantial iron and metals are likely to produce considerable methanol as well. The presence of liquid water heated by the Sun could permeate the comet’s core and engage in chemical reactions with its iron, resulting in methanol production. Thus, discovering methanol in the coma might indicate a metal-rich composition of the comet, he adds.

I’ve Spent Hours Listening to Sabrina Carpenter This Year—So Why is My Spotify “Listening Age” 86?

“Age is merely a number, so try not to take it to heart.” Those words were my first signal that I was about to encounter some troubling news.

After celebrating my 44th birthday on Wednesday, I woke up nursing a slight hangover. Unfortunately for me, that day was also when Spotify unveiled its “Spotify Wrapped,” a breakdown of the 4,863 minutes (in my case) I spent enjoying music on their platform over the last year. For the first time, they introduced a feature calculating the “listening age” of all users.

“You can’t define your musical taste,” the Spotify report informed me. “But let’s give it a shot… Your hearing age is 86.” The figure flashed on the screen in bold pink letters.

It took my 13-year-old daughter (listening age: 19) and my 46-year-old husband (listening age: 38) quite a while to stop chuckling at my expense. I felt much older than my 44 years, pondering where I had gone wrong.

But it seems I’m not alone. “Raise your hand if you feel personally attacked by the Spotify Wrapped listening age,” one user remarked on X. Another post featured a humorous video of Judi Dench exclaiming “not young” at Cate Blanchett, which has garnered over 26,000 likes. The 22-year-old actor Louis Partridge perfectly captured my sentiments when he shared on his Instagram Stories that his listening age was 100, captioned: “Ugh.”

“Rage bait” (defined as online content crafted to provoke anger to boost web traffic) has been designated as the Oxford English Dictionary’s word of the year. To me, that cheeky message from Spotify advising me to not take personal assessments of my listening habits felt like a prime example of this.

“How can I still enjoy it at 86?” I was infuriated with my family and friends, questioning whether my most listened-to artist this year was the 26-year-old Sabrina Carpenter. After taking my daughter to Carpenter’s concert in Hyde Park this summer, I had listened to her tracks for 722 minutes, placing me “in the top 3% of fans worldwide.”

The only justification Spotify provided for my 86-year listening age was that I “embraced late 50s music” this year. Yet, my top 10 songs were all released within the last five years, and my top five artists included Olivia Dean and Chapel Lawn (who just released her debut album in 2023).

Sure, Ella Fitzgerald is among them. But her music is eternal, which made me even angrier. “Isn’t it true that everyone listens to Ella Fitzgerald?” I questioned. “That’s not accurate,” my daughter kindly retorted. “No way,” my husband added.

It’s also true that I occasionally enjoy folk music from the legendary 50s and 60s, like Pete Seeger, Bob Dylan, and Joan Baez. However, when we examined the top 50 “most listened to” songs, almost all of them (80%) were from the last five years.

What’s particularly aggravating is that Spotify recognizes my musical preferences as “eclectic.” That’s how they characterize my tastes. Apparently, I listened to 210 genres and 409 artists this past year.

None of this holds any weight until we see how much Spotify benefits from triggering the outrage of users like me. Within the first 24 hours, this year’s Wrapped campaign saw 500 million shares across social media, marking a 41% increase from last year.

According to Spotify, the concept of listening age stems from the “reminiscence bump,” which they describe as “the tendency for individuals to connect most with music from their youth.” To determine this, they analyzed the release dates of all the songs I played this year and identified five years of music that resonated with me more than with other listeners my age, then “jokingly” suggested that I share the same age as those who enjoyed that music during its prime.

In other words, irrespective of your actual age, the more unique, peculiar, and outdated your musical preferences are compared to others, the more likely Spotify will mock some of the tracks you love.

But now that you comprehend this, you know precisely how to respond instead of falling for the bait. I approach a dusty old CD player. I insert a beloved CD I bought during my teenage years. I crank the volume to maximum and then play one of my favorite tracks. This song is Ella Fitzgerald’s “You Make Me Feel So Young,” a tune that every listener over the age of 86 surely knows by heart, just like I do.

How Noise Reduction Technology May Subtly Alter Your Brain Function

Noise-canceling headphones function by utilizing a microphone that detects external sounds. Through sophisticated electronics, these sounds are ‘cancelled’ by playing an inverted wave to the listener, which diminishes the audio signal reaching the eardrum.

This mechanism is akin to how a car’s active suspension mitigates vibrations from uneven roads.

The outcome is that listeners enjoy crystal-clear audio with almost no interference from background noise.

Moreover, these headphones help safeguard your ears from high volume levels. By reducing background noise, your device doesn’t need to produce sound as loudly. Hence, parents globally often encourage their children to wear headphones.










Sounds advantageous, right? But then I began hearing stories about young people facing increasing challenges, such as Auditory Processing Disorder (APD).

These individuals frequently struggle to comprehend sounds and speech amidst distracting background noise.

The underlying causes may be linked to a notable rise in young people using noise-canceling headphones and relying on subtitles while watching videos.

Instead of their brains developing typically and learning to filter the noisy environment, they wear noise-canceling headphones for extended periods, regardless of their location, thereby not allowing their brains to adapt properly.

Our brains function like muscles; they evolve in response to external stimuli.

Just as biking 100 miles a day will sculpt your thighs, your auditory processing skills may weaken if you expose yourself solely to pure audio without any background noise, leaving you unable to process multiple sounds simultaneously.

Auditory therapy can be beneficial in retraining the brain, but the optimal approach is to engage more with the world around you before complications develop. Over-isolating ourselves may lead to greater issues.


This article addresses the question (submitted by Mary Watkins): “Can noise-canceling headphones harm your ears?”

Microscopic Images Unveil the Remarkable Complexity of the Tiny World

Michael Benson’s photograph of an insect fly, with the flower and fly measuring just over 1 cm in diameter.

© 2025 Michael Benson

Inside a drawstring bag, you’ll find equipment like bug nets, tweezers, and small plastic vials. This may seem unusual for a photographer, but for Michael Benson, it’s just part of his routine. He dedicated over six years to gathering specimens for his latest publication, Nanocosmos: A Journey Through Electronic Space, a collection showcasing the microscopic realm in exquisite detail.

“I’m fascinated by the boundary between known and unknown territories—an area often linked to science,” he shares. “However, I approach it as an artist, not a scientist.”

That didn’t deter Benson from utilizing tools typically reserved for physicists and biologists. He produced all images for Nanocosmos using a formidable scanning electron microscope (SEM). This advanced technique employs a highly focused electron beam to intricately map surface contours. The resulting images portray submillimeter objects with such clarity that they appear almost extraterrestrial.

Take, for instance, the Acilidae musbifolia (as seen in the main image) alongside a flowering plant in Alberta, Canada. Even together, they span only slightly more than 1 cm. But with SEM technology, we can observe nearly every hair on the fly’s body, each claw on its legs, and even some of the countless individual receptors forming its bulging eyes.

Benson first utilized SEM in 2013 at the Massachusetts Institute of Technology’s Media Lab. “Learning to master SEM was challenging, requiring several years of practice,” he notes. Every specimen must be coated with “a molecularly thin layer of platinum to prevent charging by the electron beam,” and meticulously dried to maintain surface details.

Cloudflare Outage Disrupts Websites Including LinkedIn and Zoom

A variety of websites, such as LinkedIn, Zoom, and Downdetector, experienced outages on Friday morning due to another incident involving Cloudflare. This marks the company’s second disruption within a month.

Cloudflare reported that the outage was triggered by adjustments made to their firewalls intended to protect customers from a widespread software vulnerability disclosed earlier this week, clarifying it was not the result of a cyber attack. Previously, another issue was observed concerning their application programming interface.

The incident lasted approximately 30 minutes, concluding shortly after 9 a.m. Japan time. This follows a larger Cloudflare outage in mid-November that impacted platforms like X, OpenAI, and Spotify, along with online games such as League of Legends.

The underlying issue was identified as “configuration files that are automatically generated to manage threat traffic,” which exceeded expected sizes, leading to a crash of the software system responsible for handling traffic across various Cloudflare services.

Friday’s malfunction appeared relatively minor, affecting sites including Canva, Shopify, and the India-based brokerage firm Groww, alongside LinkedIn, Zoom, and Downdetector, which tracks online service issues. Downdetector recorded over 4,500 reports related to Cloudflare once the services resumed.

Given the recent series of prominent internet outages, some businesses might be reevaluating their reliance on Cloudflare’s offerings.

Stephen Murdoch, a computer science professor at University College London, noted, “Given these two outages within such a brief timeframe, it’s likely people will begin to question their reliability. They’re not satisfied, and Cloudflare isn’t happy either. They apologize, but it’s premature to determine if there’s a systemic problem, like software misuse, or just unfortunate timing.”

Murdoch emphasized that Cloudflare, known for its global cloud services and cybersecurity, promotes itself on its reliability. Businesses utilize its services for enhanced immunity against specific cyber threats, improved website performance, faster load times, and greater resilience to server failures.

The recent outages from Amazon Web Services, including one in October that affected over 2,000 businesses globally, have sparked discussions among experts about whether major internet services are becoming overly centralized and thus more vulnerable.

“There’s significant centralization occurring,” Murdoch stated. “Cloudflare offers an excellent product and is widely used, which introduces potential vulnerabilities.”

“This highlights yet again how exposed the major tech internet is,” remarked Michał “Risiek” Wojniak, an expert on DNS and internet infrastructure. “This marks the fourth major global outage since October 20th that has drawn the attention of media outside of the tech sphere and affected everyday users around the globe.”

Skip past newsletter promotions

According to Cloudflare, around 20% of all websites utilize its services in one form or another. The company boasts nearly 300,000 clients in 125 countries and claims to thwart billions of cyberattacks against its users on a daily basis, generating over $500 million (£440 million) each quarter.

Wojniak stated that the recent outages raise questions about Cloudflare’s marketing strategy, which promotes reliability and resilience alongside the common belief that larger enterprises are safer partners than smaller infrastructure providers.

“These companies are growing too large to fail, and their extensive traffic handling means that when they do encounter issues, it leads to significant problems very quickly,” he added.

Conversely, Murdoch suggested that the outages could be an opportunity for Cloudflare. “When AWS went down, its stock price actually increased because people recognized the scale of its usage. [The outage] serves as effective marketing, demonstrating the widespread reliance on Cloudflare.”

How Australian Teens Are Finding Ways to Navigate Social Media Bans

SEI 276876107

Australia will restrict social media use for individuals under 16 starting December 10th.

Mick Tsikas/Australian Associated Press/Alamy

A historic initiative to prohibit all children under 16 from accessing social media is about to unfold in Australia, but teens are already pushing back.

Initially announced last November, this prohibition, proposed by Australian Prime Minister Anthony Albanese, will commence on December 10th. On this date, all underaged users of platforms like Instagram, Facebook, TikTok, YouTube, and Snapchat will have their accounts removed.

Companies operating social media platforms may incur fines up to A$49.5 million (£25 million) if they do not comply by expelling underage users. Nonetheless, neither parents nor children face penalties.

This regulation is garnering global attention. The European Commission is considering a similar rule. So far, discussions have centered on implementation methods, potential age verification technologies, and the possible adverse effects on teens who depend on social media to engage with their peers.

As the deadline approaches, teens preparations are underway to defy these restrictions. A significant illustration is of two 15-year-old boys from New South Wales, Noah Jones and Macy Neyland, who are challenging the social media ban in the nation’s highest court.

“The truth is, kids have been devising ways to bypass this ban for months, but the media is only catching on now that the countdown has begun,” Jones remarked.

“I know kids who stash their family’s old devices in lockers at school. They transferred the account to a parent or older sibling years ago and verified it using an adult ID without their parents knowing. We understand algorithms, so we follow groups with older demographics like gardening or walking for those over 50. We engage in professional discussions to avoid detection.”

Jones and Neyland first sought an injunction to postpone the ban but opted instead to present their opposition as a specific constitutional challenge.

On December 4, they secured a crucial victory as the High Court of Australia agreed to hear their case as early as February. Their primary argument contends that the ban imposes an undue burden on their implied freedom of political speech. They argue this policy would compromise “significant zones of expression and engagement in social media interactions for 13- to 15-year-olds.”

Supported by the Digital Freedom Project, led by New South Wales politician John Ruddick, the duo is rallying for their cause. “I’ve got an 11-year-old and a 13-year-old, and they’ve been mentioning for months that it’s a hot topic on the playground. They’re all active on social media, reaping its benefits,” Ruddick shared.

Ruddick noted that children are already brainstorming methods to circumvent the ban, exploring options like virtual private networks (VPNs), new social media platforms, and tactics to outsmart age verification processes.

Katherine Page Jeffrey, a researcher at the University of Sydney, mentioned that the impending ban is starting to feel tangible for teenagers. “Up until now, it seems young people hadn’t quite believed that this was actually happening,” she commented.

She adds that her children have already begun discussing alternatives with peers. Her younger daughter has downloaded another social media app called Yope, which is not listed on the government’s watch list yet, unlike several others like Coverstar and Lemon8 that have been warned to self-regulate.

Lisa Given, a researcher at RMIT University in Melbourne, believes that as children drift to newer, less known social media platforms, parents will struggle to monitor their children’s online activities. She speculated that many parents may even assist their children in passing age verification hurdles.

Susan McLean, a foremost cybersecurity expert in Australia, argued that this situation will lead to a “whack-a-mole” scenario as new apps emerge, kids flock to them, and the government continually adds them to the banned list. She insists that rather than taking social media away from teenagers, governments should compel large companies to rectify algorithms that expose children to inappropriate content.

“The government’s logic is deeply flawed,” she pointed out. “You can’t prohibit a pathway to safety unless you ban all communications platforms for kids.”

McLean shared a poignant quote from a teenager who remarked, “If the aim of this ban is to protect children from harmful adults, why should I have to leave while those harmful adults remain?”

Noah Jones, one of the teen complainants, stated it bluntly: “There’s no greater news source than what you can find in just 10 minutes on Instagram,” he insisted. “Yet, we faced bans while perpetrators went unpunished.”

Home Office Acknowledges Issues with Facial Recognition Technology for Black and Asian Individuals

Ministers are under pressure to implement more robust safeguards for facial recognition technology, as the Home Office has acknowledged that it may mistakenly identify Black and Asian individuals more frequently than white people in certain contexts.

Recent tests conducted by the National Physical Laboratory (NPL) on how this technology functions within police national databases revealed that “some demographic groups are likely to be incorrectly included in search results,” according to the Home Office.

The Police and Crime Commissioner stated that the release of the NPL’s results “reveals concerning underlying bias” and urged caution regarding plans for a nationwide implementation.

These findings were made public on Thursday, shortly after Police Minister Sarah Jones characterized the technology as “the most significant advancement since DNA matching.”

Facial recognition technology analyzes individuals’ faces and cross-references the images against a watchlist of known or wanted criminals. It can be employed to scrutinize live footage of people passing in front of cameras, match faces with wanted persons, or assist police in targeting individuals on surveillance.

Images of suspects can be compared against police, passport, or immigration databases to identify them and review their backgrounds.

Analysts who evaluated the Police National Database’s retrospective facial recognition tool at lower settings discovered that “white subjects exhibited a lower false positive identification rate (FPIR) (0.04%) compared to Asian subjects (4.0%) and Black subjects (5.5%).”

Further testing revealed that Black women experienced notably high false positives. “The FPIR for Black male subjects (0.4%) is lower than that for Black female subjects (9.9%),” the report detailed.

The Police and Crime Commissioners Association stated that these findings reflect internalized bias. “This indicates that, in certain scenarios, Black and Asian individuals are more prone to incorrect matches than their white counterparts. Although the terminology is technical, it is evident that this technology is being integrated into police operations without adequate safeguards,” the report noted.

The statement, signed by APCC leaders Darryl Preston, Alison Rowe, John Tizard, and Chris Nelson, raised concerns why these findings were not disclosed sooner and shared with Black and Asian communities.

The report concluded: “While there is no evidence of adverse effects in individual cases, this is due to chance rather than a systematic approach. System failures have been known for a while, but the information was not conveyed to the communities impacted and key stakeholders.”

The government has initiated a 10-week public consultation aimed at facilitating more frequent usage of the technology. The public will be asked if police should have permission to go beyond records and access additional databases, such as images from passports and driving licenses, to track criminals.

Civil servants are collaborating with police to create a new national facial recognition system that will house millions of images.

Charlie Welton, head of policy and campaigns at Liberty, stated: “The racial bias indicated by these statistics demonstrates that allowing police to utilize facial recognition without sufficient safeguards leads to actual negative consequences. There are pressing questions regarding how many individuals of color were wrongly identified in the thousands of monthly searches utilizing this biased algorithm and the ramifications it might have.”

“This report further underscores that this powerful and opaque technology cannot be deployed without substantial safeguards to protect all individuals, which includes genuine transparency and significant oversight. Governments must halt the accelerated rollout of facial recognition technology until protections are established that prioritize our rights, aligning with public expectations.”

Former cabinet minister David Davis expressed worries after police officials indicated that cameras could be installed at shopping centers, stadiums, and transport hubs to locate wanted criminals. He told the Daily Mail: “Brother, welcome to the UK. It is evident that the Government is implementing this dystopian technology nationwide. There is no way such a significant measure could proceed without a comprehensive and detailed discussion in the House of Commons.”

Officials argue that the technology is essential for apprehending serious criminals, asserting that there are manual safeguards embedded within police training, operational guidelines, and practices that require trained personnel to visually evaluate all potential matches derived from the police national database.

A Home Office representative said: “The Home Office takes these findings seriously and has already acted. The new algorithm has undergone independent testing and has shown no statistically significant bias. It will be subjected to further testing and evaluation early next year.”

“In light of the significance of this issue, we have requested the Office of the Inspector General and the Forensic Regulator to review the application of facial recognition by law enforcement. They will evaluate the effectiveness of the mitigation measures, and the National Council of Chiefs of Police backs this initiative.”

Study Shows Humans Struggle to Accurately Interpret Dog Emotions

We often believe we can accurately gauge our dogs’ emotions, yet recent studies indicate that many of us may be misunderstanding their feelings.

Researchers at Arizona State University (ASU) discovered that when individuals are in a good mood, they are more prone to perceive their dog as looking sad. Conversely, when experiencing mild depression, they are likely to view the same dog as happy.

This contrasts with how we interpret human emotions. In social interactions, we generally perceive others’ feelings as mirroring our own.

“I am continually fascinated by how people interpret emotions in dogs,” stated the study’s co-author, Clive Wynn. “We have only begun to uncover what is shaping up to be a significant mystery.”

The researchers believe these findings could greatly influence how we care for our pets.

“By enhancing our understanding of how we recognize emotions in animals, we can improve their care,” explained the first author, Dr. Holly Molinaro, who was a doctoral student at ASU focused on animal behavior at the time.

Dogs involved in the study, from left to right: Canyon, a 1-year-old Catahoula; Henry, a 3-year-old French Bulldog; and Oliver, a 14-year-old mongrel. The video background was black, ensuring only the dogs were visible. – Credit: Arizona State University

The research stemmed from two experiments with about 300 undergraduate students.

Participants first viewed images designed to evoke positive, negative, or neutral moods. They then watched a brief video featuring an adorable dog to assess its emotional state.

Those who saw uplifting images rated the dog in the video as sadder, while participants who viewed more somber images rated it as happier.

The video included three dogs—Oliver, Canyon, and Henry—depicted in scenarios reflecting cheerful, anxious, or neutral moods. Factors like snacks, toys, and the promise of visiting “Grandma” elevated their spirits, while a vacuum cleaner and a photo of a cat were used to bring them down.

Scientists are still puzzled about why humans misinterpret dogs’ emotions. “Humans and dogs have coexisted closely for at least 14,000 years,” Wynn noted.

“Over this time, dogs have learned much about cohabitation with humans. However, our research indicates significant gaps in our understanding of how dogs truly feel.”

EU Fines Elon Musk’s X €120 Million in First Enforcement of New Digital Law

Elon Musk’s social media platform X has received a €120m (£105m) fine from the European Commission after being found in violation of new EU digital laws. This high-profile ruling is expected to cause friction with US billionaire Donald Trump.

The violations include what the EU described as “misleading” blue checkmark verification badges given to users, as well as insufficient transparency in advertising practices, which have been under investigation for two years.

The EU’s regulations mandate that tech companies maintain public lists of advertisers to ensure their structures prevent illegal fraud, false advertising, and organized political campaign manipulations.

Additionally, the EU found that X had not granted sufficient access to public data typically available to researchers observing critical topics like political content.

This significant ruling marks the conclusion of an inquiry that started two years ago.

On Friday, the commission announced that X had failed to meet its transparency responsibilities under the Digital Services Act (DSA), marking the first judgment against the platform since the enforcement of regulations on social media and major tech platforms began in 2023.

In December 2023, the Commission began formal proceedings to determine if X violated the DSA regarding illegal content distribution and the effectiveness of measures to address information manipulation, with the investigation ongoing.

Under the DSA, X could face fines of up to 6% of its global revenue, which is projected to be between $2.5bn and $2.7bn (£1.9bn and £2bn) in 2024.

There are still three additional investigations underway, two of which examine alterations to content and algorithms implemented after Musk’s acquisition of Twitter in October 2022, when it was rebranded to “X.”

The commission is also exploring whether laws against inciting violence or terrorism have been violated.

Moreover, the company is evaluating a system that would permit users to report and flag content they suspect to be illegal.

The fine, divided into three components, includes a €45 million penalty for the introduction of a blue “authentication” checkmark that users could purchase, which obscured the reliability of account holders, according to senior officials.

Prior to Musk’s takeover, blue checkmarks were exclusively awarded to verified account holders, including politicians, celebrities, public bodies, and established journalists from mainstream and emerging media like bloggers and YouTubers. Following the acquisition, users subscribing to X Premium can now obtain blue check status.

“With the DSA’s first compliance decision, we aim to hold Company X accountable for infringing on users’ rights and evading responsibility,” stated Hena Virkunen, executive vice president of the European Commission overseeing technology regulation.

“Deceiving users with blue checkmarks, obscuring information in advertisements, or restricting access for researchers is unacceptable online within the EU.”

X was also fined €35 million for advertising violations and €40 million for failures related to data access for researchers.

This ruling could provoke backlash from the Trump administration. Recently, US Commerce Secretary Howard Lutnick stated that the EU might have to explore technical regulations to cut steel tariffs by 50%.

His statement was labeled “blackmail” by Spanish commissioner Teresa Rivera.

EU officials asserted that the ruling stands independent of allegations brought forth by a US delegation meeting with trade ministers in Brussels last week. The EU emphasized its right to regulate US tech firms, noting that 25 companies, including non-US entities like TikTok, must adhere to the DSA.

Musk, who is on the path to becoming the first trillionaire, has 90 days to draft an “action plan” to address the fine, though he remains free to contest the EU’s decision, similar to appeals made by other corporations like Apple to the European Court of Justice.

In contrast, the EU announced it had secured a commitment from TikTok to establish an advertising repository, addressing transparency concerns raised with the European Commission earlier this year.

The DSA mandates that platforms maintain accessible and searchable ad repositories to enable researchers and civil society representatives to detect fraudulent, illegal, or age-inappropriate advertisements.

Government officials indicated that the emerging issue of fraudulent political ads and ads featuring impersonated celebrities cannot be adequately analyzed without compliance from social media companies.

Mr. X has been contacted for commentary. The EU confirmed that the company has been made aware of the decision.

Teens Seek Alternatives to Australia’s Social Media Ban: Where Will They Turn?

As Australia readies itself to restrict access to 10 major social media platforms for users under 16, lesser-known companies are targeting the teen demographic, often engaging underage influencers for promotional content.

“With a social media ban on the horizon, I’ve discovered a cool new app we can switch to,” stated one teenage TikTok influencer during a sponsored “collaboration” video on the platform Coverstar.

New social media regulations in Australia will take effect, effectively prohibiting all users under 16 from accessing TikTok, Instagram, Snapchat, YouTube, Reddit, Twitch, Kick, and X starting December 10.

It remains uncertain how effective this ban will be, as numerous young users may attempt to bypass it. Some are actively seeking alternative social media platforms.

Sign up: AU breaking news email

Alongside Coverstar, other lesser-known apps like Lemon8 and Yope have recently surged in popularity, currently sitting at the top two spots in Apple’s lifestyle category in Australia.


The government has stated that the list of banned apps is “dynamic,” meaning additional platforms may be added over time. Experts have voiced concerns that this initiative might lead to a game of “whack-a-mole,” pushing children and teens into less visible corners of the internet.

Dr. Catherine Page-Jeffrey, a specialist in digital media and technology at the University of Sydney, remarked, “This legislation may inadvertently create more dangers for young people. As they migrate to less regulated platforms, they might become more secretive about their social media activities, making them less likely to report troubling content or harmful experiences to their parents.”

Here’s what we know about some of the apps that kids are opting for.

Coverstar

Coverstar, a video-sharing app based in the U.S., identifies itself as “a new social app for Generation Alpha that emphasizes creativity, utilizes AI, and is deemed safer than TikTok.” Notably, it is not subject to the social media ban and currently holds the 45th position in Apple’s Australian download rankings.

Children as young as 4 can use this platform to livestream, post videos, and comment. For users under 13, the app requires them to record themselves stating, “My name is ____. I give you permission to use Coverstar,” which the app then verifies. Adults are also permitted to create accounts, post content, and engage in comments.

Similar to TikTok and Instagram, users can spend real money on virtual “gifts” for creators during live streams. Coverstar also offers a “premium” subscription featuring additional functionalities.

The app highlights its absence of direct messaging, adherence to an anti-bullying policy, and constant monitoring by AI and human moderators as key safety measures.

Dr. Jennifer Beckett, an authority on online governance and social media moderation at the University of Melbourne, raised concerns regarding Coverstar’s emphasis on AI: “While AI use is indeed promising, there are significant limitations. It’s not adept at understanding nuance or context, which is why human oversight is necessary. The critical question is: how many human moderators are there?”

Coverstar has been reached for comments.

Lemon8

Lemon8, a photo and video sharing platform reminiscent of Instagram and owned by TikTok’s parent company, ByteDance, has experienced a notable rise in user engagement recently.

Users can connect their TikTok accounts to easily transfer content and follow their favorite TikTok creators with a single click.

However, on Tuesday, Australian eSafety Commissioner Julie Inman-Grant revealed that her office has advised Lemon8 to conduct a self-assessment to ascertain if it falls under the new regulations.

Yope

With only 1,400 reviews on the Apple App Store, Yope has emerged as a “friends-only private photo messaging app” that is positioned as an alternative to Snapchat after the ban.

Bahram Ismailau, co-founder and CEO of Yope, described the company as “a small team dedicated to creating the ideal environment for teenagers to share images with friends.”

Similar to Lemon8, Australia’s eSafety Commissioner also reached out to Yope, advising a self-assessment. Ismailau informed the Guardian that he had not received any communication but is “prepared to publicly express our overall eSafety policy concerning age-restricted social media platforms.”

He claimed that after conducting a self-assessment, Yope determines it fully meets the law’s exemption for apps designed solely for messaging, email, video calls, and voice calls.


Australian government adds Reddit and Kick to social media ban for under-16s – video


“Yope functions as a private photo messenger devoid of public content,” asserted Ismailau. “It’s comparable in security to iMessage or WhatsApp.”

According to Yope’s website, the app is designed for users aged 13 and above, with those between 13 and 18 required to engage a parent or guardian. However, the Guardian successfully created an account for a fictitious four-year-old named Child Babyface without needing parental consent.

A mobile number is mandatory for account creation.

Ismailau did not address inquiries about under-13 accounts directly but confirmed that plans are underway to update the privacy policy and terms of service to better reflect the app’s actual usage and intended audience.


Red Note

The Chinese app Red Note, also referred to as Xiaohongshu, attracted American users when TikTok faced a temporary ban in the U.S. earlier this year.

Beckett noted that the app might provide a safe space, considering that “Social media is heavily regulated in China, which is reflected in the content requiring moderation.”

“Given TikTok’s previous issues with pro-anorexia content, it’s clear that the platform has faced its own challenges,” she added.

Nonetheless, cybersecurity experts highlight that the app collects extensive personal information and could be legally obligated to share it with third parties, including the Chinese government.

Despite the increasing number of restricted social media services, specialists assert that governments are underestimating children’s eagerness to engage with social media and their resourcefulness in doing so.

“We often overlook the intelligence of young people,” Beckett remarked. “They are truly adept at finding ways to navigate restrictions.”

Anecdotal evidence suggests that some kids are even exploring website builders to create their own forums and chat rooms; alternatives include using shared Google Docs for communication.

“They will find ways to circumvent these restrictions,” Beckett asserted. “They will be clever about it.”

Exposing Degradation: The Tale of Deepfakes, the Infamous AI Porn Hub | Technology

Patrizia Schlosser’s ordeal began with a regretful call from a colleague. “I found this. Did you know?” he said, sharing a link that led her to a site called Mr. DeepFakes. Here, she was horrified to discover fabricated images portraying her in degrading scenarios, labeled “Patrizia Schlosser’s slutty FUNK whore” (sic).

“They were highly explicit and humiliating,” noted Schlosser, a journalist for North German Radio (NDR) and funk. “Their tactics were disturbing and facilitated their ability to distance themselves from the reality of the fakes. It was unsettling to think about someone scouring the internet for my pictures and compiling such content.”

Despite her previous investigations into the adult film sector, this particular site was unfamiliar. “I had never come across Mr. DeepFakes before. It’s a platform dedicated to fake pornographic videos and images. I was taken aback by its size and the extensive collection of videos featuring every celebrity I knew.” Initially, Schlosser attempted to ignore the images. “I shoved it to the back of my mind as a coping mechanism,” she explained. “Yet, even knowing it was fake, it felt unsettling. It’s not you, but it is you—depicted alongside a dog and a chain. I felt violated and confused. Finally, I resolved to act. I was upset and wanted those images removed.”

With the help of NDR’s STRG_F program, Schlosser successfully eliminated the images. She located the young man responsible for their creation, even visiting his home and conversing with his mother (the perpetrator himself remained hidden away). However, despite collaboration with Bellingcat, she could not identify the individual behind Mr. Deepfake. Ross Higgins, a member of the Bellingcat team, noted, “My background is in money laundering investigations. When we scrutinized the site’s structure, we discovered it shared an internet service provider (ISP) with a legitimate organized crime group.” These ISPs hinted at connections to the Russian mercenary group Wagner and individuals mentioned in the Panama Papers. Additionally, advertisements on the site featured apps owned by Chinese tech companies that provided the Chinese government with access to user data. “This seemed too advanced for a mere hobbyist site,” Higgins remarked.

And indeed, that was just the beginning of what unfolded.

The narrative of Mr. Deepfakes, recognized as the largest and most infamous non-consensual deepfake porn platform, aligns closely with the broader story of AI-generated adult content. The term “deepfake” itself is believed to have originated with its creator. This hub of AI pornography, which has been viewed over 2 billion times, features numerous female celebrities, politicians, European royals, and even relatives of US presidents in distressing scenarios including abductions, tortures, and extreme forms of sexual violence. Yet, the content was merely a “shop window” for the site; the actual “engine room” was the forum. Here, anyone wishing to commission a deepfake of a known person (be it a girlfriend, sister, classmate, colleague, etc.) could easily find a vendor to do so at a reasonable price. This forum also served as a “training ground,” where enthusiasts exchanged knowledge, tips, academic papers, and problem-solving techniques. One common challenge was how to create deepfakes without an extensive “dataset,” focusing instead on individuals with limited online images, like acquaintances.

Filmmaker and activist Sophie Compton invested considerable time monitoring deepfakes while developing her acclaimed 2023 documentary, Another Body (available on iPlayer). “In retrospect, that site significantly contributed to the proliferation of deepfakes,” she stated. “There was a point at which such platforms could have been prevented from existing. Deepfake porn is merely one facet of the pervasive issue we face today. Had it not been for that site, I doubt we would have witnessed such an explosion in similar content.”

The origins of Mr. Deepfakes trace back to 2017-18 when AI-generated adult content was first emerging on platforms like Reddit. An anonymous user known as “Deepfake,” recognized as a “pioneer” in AI porn, mentioned in early interviews with Vice the potential for such material. However, after Reddit prohibited deepfake pornography in early 2018, the nascent community reacted vigorously. Compton noted, “We have records of discussions from that period illustrating how the small deepfake community was in uproar.” This prompted the creation of Mr. DeepFakes, which initially operated under the domain dpfks.com. The administrator retained the same username, gathered moderators, and outlined regulations, guidelines, and comprehensive instructions for using deepfake technology.

“It’s disheartening to reflect on this chapter and realize how straightforward it could have been for authorities to curb this phenomenon,” Compton lamented. “Participants in this process believed they were invulnerable, expressing thoughts like, ‘They’ll come for us!’ and ‘They’ll never allow us this freedom!'” Yet, as they continued with minimal repercussions, their confidence grew. Moderation efforts dwindled amid the surge in popularity of their work, which often involved humiliating and degrading imagery. Many of the popular figures exploited were quite young, ranging from Emma Watson to Billie Eilish and Millie Bobby Brown, with individuals like Greta Thunberg also being targeted.

Who stands behind this project? Mr. Deepfakes occasionally granted anonymous interviews, including one in a 2022 BBC documentary entitled ‘Deepfake Porn: Can You Be Next?’, where the ‘web developer’ behind the site, who operates under the alias ‘Deepfake,’ asserted that consent from women was unnecessary because “it’s fantasy, not reality.”

Was financial gain a driving force? DeepFakes hosted advertisements and offered paid memberships in cryptocurrencies. One forum post from 2020 mentioned a monthly profit of between $4,000 and $7,000. “There was a commercial aspect to this,” Higgins stated, elaborating that it was “a side venture, yet so much more.” This contributed to its infamy.

At one time, the site showcased over 6,000 images of Alexandria Ocasio-Cortez (AOC), allowing users to create deepfake pornography featuring her likeness. “The implication is that in today’s society, if you rise to prominence as a woman, you can expect your image to be misused for baseless exploitation,” Higgins noted. “The language utilized regarding women on that platform was particularly striking,” he added. “I had to adjust the tone in the online report to avoid sounding provocative, but it was emblematic of raw misogyny and hatred.”

In April of this year, law enforcement began investigating the site, believing it had provided evidence in its communications with suspects.

On May 4th, Mr. DeepFakes was taken offline. The notice issued on the site blamed “data loss” due to the withdrawal of a “key service provider.” The message concluded with an assertion that “I will not restart this operation.” Any website claiming to be the same is false, and while this domain will eventually lapse, they distanced themselves from any future use.

Mr. Deepfake has ended—but Compton suggests it could have concluded sooner. “All indicators were present,” she commented. In April 2024, the UK government detailed plans to criminalize the creation and distribution of deepfake sexual abuse content. In response, Mr. Deepfake promptly restricted access for users based in the UK (this initiative was later abandoned amidst the 2024 election campaign). “This clearly demonstrated that Mr. Deepfakes wasn’t immune to government intervention—if it posed too much risk, they weren’t willing to continue,” Compton stated.

However, deepfake pornography has grown so widespread and normalized that it no longer relies on a singular “base camp.” “The techniques and knowledge that they were proud to share have now become so common that anyone can access them via an app at the push of a button,” Compton remarked.

For those seeking more sophisticated creations, self-proclaimed experts who once frequented forums are now marketing their services. Patrizia Schlosser has firsthand knowledge of this trend. “In my investigative work, I went undercover and reached out to several forum members, requesting deepfakes of their ex-girlfriends,” Schlosser recounted. “Many people claim this phenomenon is exclusive to celebrities, but that’s not accurate. The responses were always along the lines of ‘sure…’

“Following the shutdown of Mr. DeepFakes, I received an automated response from one of them saying something akin to: ‘If you want anything created, don’t hesitate to reach out… Mr. DeepFakes may be gone, but we’re still here providing services.’

A Major Volcanic Eruption Could Have Triggered the Black Death

A recent study suggests that volcanic eruptions from several years prior may have contributed to the devastating impact of the Black Death on medieval Europe’s population.

The researchers discovered that a period of abnormally cold summers in the mid-1340s, potentially linked to one significant volcanic eruption or several smaller ones, led to severe famines throughout the Mediterranean.

They argue that this chain reaction ultimately caused disease-carrying fleas to arrive at European ports, resulting in mortality rates of up to 60 percent.

“This is something I’ve wanted to understand for a long time,” stated Professor Wolf Bungen, a paleoclimatologist from the Department of Geography at the University of Cambridge. “What were the origins and transmission factors of the Black Death, and how extraordinary were they?”

“Why did this event occur in this specific region, at this precise moment in European history? That is a fascinating question, yet one that requires collective insights to answer.”

Bungen noted that BBC Science Focus has provided clues through tree rings and ice cores—ancient ice layers that have preserved chemicals from historic volcanic eruptions—indicating that volcanic activity contributed to the extreme climatic conditions.

“If a particular year experiences unusual cold, heat, dryness, or wetness, we aim to uncover the reasons behind it,” Bungen remarked to BBC Science Focus.

“Volcanoes emit substantial amounts of sulfur into the upper atmosphere, prompting collaborations with ice core experts to gain insights on past eruptions.

“This can lead to subsequent cold summers, a phenomenon known as post-eruption cooling.”

It was left to climate historian Dr. Martin Bauch from the Leibniz Institute for the History and Culture of Eastern Europe in Germany to correlate this climate data with historical events.

He found that the harsh cold resulted in significant famine across the Mediterranean, and the responses of the Italian republics of Venice, Genoa, and Pisa eventually facilitated the plague’s arrival in Europe.

“For over a century, these influential Italian city-states established extensive trade networks throughout the Mediterranean and Black Seas, employing an effective system to stave off starvation,” Bauch explained. “However, this ultimately contributed to even greater disasters.”

The fleas carrying the plague bacterium Y. pestis likely reached Mediterranean ports aboard these grain ships, transferring to rats, cats, and humans, and quickly propagating the disease across Europe, decimating its population.

The study concluded that volcanic activity initiated a sequence of events culminating in the plague throughout medieval Europe.

Bungen noted that this narrative continues to resonate in today’s world, over seven centuries later.

“While the coincidental convergence of factors leading to the Black Death may be rare, the probability of zoonotic disease outbreaks and pandemics amidst climate change is likely to escalate in our interconnected world,” he explained.

“This is particularly crucial in light of our recent experiences with COVID-19.”

Bolivian Fossil Site Captures Thousands of Cretaceous Dinosaur Footprints, Tail Marks, and Swim Trails

The Carreras Pampas archaeological site within Bolivia’s Toro Toro National Park has documented 1,321 tracks and 289 isolated footprints, totaling 16,600 theropod dinosaur footprints. Additionally, 280 swim tracks have been identified, amounting to 1,378 swim tracks in total. Some of the tracks include tail traces.

Bolivia boasts one of the most comprehensive and diverse records of dinosaur footprints globally, covering the Triassic, Jurassic, and Cretaceous periods.

Despite the abundance of track sites, there has been limited scientific research published.

A recent study led by paleontologist Raul Esperante from the Institute of Geosciences, along with his colleagues, has documented an extraordinary variety of dinosaur footprints at the Carreras Pampas site in Toro Toro National Park.

In nine different study areas, the research team uncovered 16,600 footprints left by three-toed theropod dinosaurs from the late Cretaceous.

These footprints vary in size from small (less than 10 cm) to large (over 30 cm) and capture a range of dinosaur behaviors, including running, swimming, tail dragging, and abrupt turns.

“The waist height of most (80%) of the trackmakers was between 65 cm and 1.15 meters, with a significant portion measuring between 75 cm and 1.05 meters,” stated the paleontologist.

“Interestingly, very few trackmakers exceeded 1.25 meters in height.”

The majority of these footprints are oriented approximately northwest to southeast, and the sediments retain ripple marks, indicating that these dinosaurs traversed ancient shorelines.

“The Carreras Pampas track set a new world record for the number of individual dinosaur footprints, continuous tracks, tail marks, and swimming marks,” the researchers noted.

“This exceptional frequency suggests it was a heavily trafficked area, and the parallel alignment of some footprints may imply groups of dinosaurs traveled together.”

“Numerous more footprints at this site and other locations in Bolivia remain to be studied,” they added.

“This site offers a remarkable glimpse into the region’s past. It reveals not only how many dinosaurs inhabited the area but also their behaviors during migration.”

“It’s truly incredible to work here, as the ground is covered with dinosaur footprints wherever you look.”

The team’s findings were published in the online journal PLoS ONE.

ESA’s JUICE Spacecraft Sends Back New Images of 3I/ATLAS

In November 2025, ESA’s Jupiter Ice Satellite Probe (Juice) utilized five scientific instruments to study 3I/ATLAS, marking the second interstellar comet ever identified in our neighboring universe. The spacecraft also captured fresh images of this interstellar traveler using its navigation camera (NavCam).

This image from ESA’s Juice spacecraft captures the interstellar comet 3I/ATLAS. Image credit: ESA / Juice / NavCam / CC BY-SA 3.0 IGO.

“Though the data from the scientific instruments won’t reach Earth until February 2026, our team was eager to see what we could find,” stated members of the Juice team.

“We opted to download just a quarter of a single NavCam image to test the waters.”

“To our astonishment, we clearly observed a comet, notably surrounded by signs of activity.”

“You can distinctly see the glowing gas surrounding the comet, referred to as the coma, along with indications of its two tails.”

“The comet’s ‘plasma tail,’ composed of electrically charged gas, stretches toward the top of the image.”

“A fainter ‘dust tail,’ made of tiny solid particles, can also be seen extending to the bottom left.”

The image of 3I/ATLAS was captured on November 2, during the initial observation window of Comet Juice.

This observation took place on November 4, just two days before Juice’s closest approach to the comet, approximately 66 million kilometers (41 million miles) away.

“On February 18 and 20, 2026, we will receive data from the five scientific instruments (JANUS, MAJIS, UVS, SWI, PEP) activated during the observation,” the researchers mentioned.

“This delay results from Juice currently using its main high-gain antenna as a heat shield against the sun, while a smaller medium-gain antenna transmits data to Earth at a slower rate.”

Even though Juice was situated farther from 3I/ATLAS than ESA’s Mars rover—which returned in October—it observed 3I/ATLAS shortly after the comet’s closest proximity to the Sun, suggesting a more active state.

“We anticipate clearer indications of this activity with data from our scientific instruments,” the scientists elaborated.

“This will encompass not only visuals from JANUS (Juice’s high-resolution optical camera), but also spectrometry data from MAJIS and UVS, compositional insights from SWI, and particle data from PEP.”

Why Is AI Driving Up the Cost of Computers and Game Consoles?

Machines for Semiconductor Chip Production

David Talukdar/Alamy

The AI industry is now heavily investing in computer memory, directly collaborating with manufacturers to develop chips worth billions. These chips are the same ones found in smartphones, laptops, and gaming consoles. This could either drive prices up significantly or cause shortages, hindering production.

What drives AI’s need for memory?

AI models are tremendously large, consisting of grids filled with billions or trillions of parameters (values stored in memory) that undergo complex and repetitive calculations. This process forms the basis of how large language models process input and generate output.

Transferring this expansive data between affordable yet slower hard drives (often referred to as storage) and the processor results in a significant bottleneck. To mitigate this, a considerable amount of faster RAM (commonly termed computer memory) is utilized.

Additionally, the models created by AI companies operate at a grand scale. This necessitates computers capable of managing hundreds, thousands, or even millions of iterations of these models to cater to numerous users simultaneously.

The growing need for handling compute-intensive activities, scaling to accommodate a large user base, and minimizing limitations on expansion through virtually limitless investments results in an unquenchable thirst for hardware. Competing with firms that produce millions of laptops annually is increasingly challenging.

Why can’t chip manufacturers increase output?

It’s more complex than it appears. Semiconductor factories face production capacity limits, and establishing a new facility demands substantial investment and often spans several years.

Additionally, there are indications that manufacturers may not wish for the current scarcity to subside. Reports from Korean media suggest that Samsung Electronics and SK Hynix dominate chip production, collectively accounting for roughly 70 percent. Averse to augmenting supply, they risk having new chip factories remain underutilized during a downturn in the AI sector.

With current demand flourishing, Samsung is in a position to: raise prices as much as 60%. Why would they disrupt this momentum? For instance, a 32-gigabyte chip sold by Samsung for $149 in September is priced at $239 by November.

Have shortages like this been experienced before?

Indeed. The surge in AI has compelled firms to aggressively accumulate graphics processing unit (GPU) chips to construct extensive data centers for training and running increasingly larger models. This persistent demand has driven Nvidia’s stock price up from $13 at the beginning of 2021 to over $200 recently.

The year 2021 also witnessed widespread chip shortages across the board, triggered by a combination of the global pandemic, trade disputes, natural disasters, and extreme weather events. This disruption impacted the production of items ranging from pickup trucks to microwave ovens.

That same year experienced storage shortages as a new cryptocurrency known as Chia, which depends on storage space rather than raw computing power, gained rapid popularity.

In summary, technological advancements are outpacing developments in global supply chains.

When could this shortage end?

Not in the immediate future. OpenAI has entered into contracts with Samsung and SK Hynix that will likely dictate delivery timelines, possibly consuming 40% of global memory supply. However, this represents just one AI entity; Microsoft, Google, ByteDance, and others are similarly seeking to acquire as many chips as possible.

The resolution of this shortage may hinge on whether the anticipated AI downturn, frequently mentioned by economists and industry leaders, actually materializes, potentially leading to a surplus. However, this scenario poses risks of severe financial repercussions.

Should such a downturn not occur, projections suggest it may not settle until 2028, when new factories from smaller firms begin to contribute, allowing supply and demand to reach some semblance of balance.

Some experts indicate that this prolonged shortage could become a broader manufacturing challenge. Sanchit Vir Gogia, an industry analyst at Greyhound Research, noted to Reuters, “Memory shortages have evolved from a component-level issue to a macroeconomic concern.”

AI’s Impact on Voter Sentiment: Implications for Democracy

AI chatbots may have the potential to sway voter opinions

Enrique Shore / Alamy

Could the persuasive abilities of AI chatbots signal the decline of democracy? A substantial study investigating the impact of these tools on voter sentiments revealed that AI chatbots surpass traditional political campaign methods, such as advertisements and pamphlets, in persuasiveness, rivaling seasoned campaigners as well. However, researchers see reasons for cautious optimism regarding how AI influences public opinion.

Evidence shows that AI chatbots, like ChatGPT, can migrate the beliefs of conspiracy theorists, winning converts to more reasonable positions and attracting support during human debates. This capability raises valid worries about AI possibly skewing the digital scales that determine election results or being misused by malicious entities to manipulate users towards certain political figures.

The concerning part is that these fears have merit. A survey involving thousands of voters who participated in recent elections in the US, Canada, and Poland found that David Rand and researchers at MIT discovered that AI chatbots effectively swayed individuals to back specific candidates or alter their stance on certain issues.

“Conversations with these models can influence attitudes towards presidential candidates—contributions often deemed deeply entrenched—more than previous studies would suggest,” Rand remarks.

In their American election analysis, Rand’s team surveyed 2,400 voters, asking them about the most significant policy issues or characteristics of a potential president. Subsequently, voters rated their preferences for the leading candidates, Donald Trump and Kamala Harris, on a 100-point scale and answered additional questions to clarify their choices.

The answers were inputted into a chatbot, such as ChatGPT, with the objective of persuading the voters to support an already favored candidate or switch their support to a less favored one. The interaction took about six minutes, consisting of three question-and-answer exchanges.

Following the AI interaction and a one-month follow-up, Rand’s team discovered that voters adjusted their candidate preferences by an average of 2.9 points.

Furthermore, the researchers examined AI’s capacity to influence views on specific policies and noticed a substantial change in opinions regarding the legalization of psychedelics, shifting voter support by approximately 10 points. In comparison, video ads impacted views by only about 4.5 points, and text ads swayed opinions by merely 2.25 points.

The magnitude of these findings is remarkable. Sasha Altai of the University of Zurich stated, “These effects are considerably larger than those typically observed with traditional political campaigning and are comparable to the influence stemming from expert discussions.”

Nevertheless, the study reveals a more hopeful insight: these persuasive interactions predominantly stemmed from fact-based arguments rather than personalized content, which tends to exploit users’ personal information available to political operatives.

Another study of approximately 77,000 individuals in the UK assessed 19 extensive language models across 707 distinct political issues, concluding that AI performed best when employing fact-based arguments, as opposed to tailoring its discussions to the individual.

“Essentially, it’s about creating a compelling argument that prompts a mindset shift,” Rand explains.

“This bodes well for democracy,” notes Altai. “It indicates that individuals are often more influenced by factual evidence than by personalized or manipulative strategies.”

There is a need for further research to confirm these findings, asserts Claes de Vries at the University of Amsterdam. He adds that if replicated, the controlled environments of these studies—where participants engaged with chatbots extensively—might differ significantly from individuals’ typical political interactions with friends or colleagues.

“The structured setting of interaction about politics with a chatbot is quite different from how people usually engage with political matters,” he mentions.

Despite this, De Vries notes growing evidence that individuals are indeed turning to AI chatbots for political advice. A recent survey of over 1,000 voters in the Netherlands ahead of the 2025 national elections found that about 10% sought AI guidance regarding candidates, political parties, and election matters. “This trend is particularly noteworthy as the elections approach,” De Vries points out.

Even if people’s engagements with chatbots are brief, De Vries asserts that the integration of AI into political processes seems unavoidable, as politicians seek tools for policy recommendations or as AI generates political advertisements. “As researchers and as a society, we must recognize that generative AI is now a vital aspect of the electoral process,” he states.

Stop Treating Your Pet Like a Toy: It Could Harm Their Health.

New Scientist. Our website and magazine provide science news and in-depth articles by expert journalists focusing on advancements in science, technology, health, and the environment.

Once commonplace pets in our yards have transitioned, for better or worse, into pampered “fur babies.” The American Veterinary Medical Association recently noted that pet owners are anticipated to spend nearly $1 billion on pet costumes this year. While many consider this harmless entertainment, the increasing trend of treating pets like surrogate children can pose significant risks to the health and well-being of the animals involved.

The ancestors of today’s fur babies belonged to a group of small, domesticated carnivores within the Canis and Felis genera, distributed worldwide. Even though these pets often have a shorter lifespan, they provide immense joy, companionship, and health benefits to their human companions, teaching children respect for animals and their basic needs.

Additionally, pets offer educational advantages, such as helping individuals experience and process non-human death, preparing them for the loss of human loved ones. Most pets receive basic necessities like food, water, shelter, and vaccinations, along with names that represent their traits or characteristics (e.g., Fido, Sooty, Rover). Crucially, many are assured a relatively peaceful end before the wear of old age diminishes their quality of life.

The shift from pets to fur babies can be attributed to various factors, including an overemphasis on the human-animal bond, rising affluence, lack of understanding of animals’ biological requirements, rampant consumerism, and reckless (though well-intentioned) anthropomorphism. The principal causes and effects of fur baby culture are intensifying and spreading globally. This is evident not only in the availability of costumes for special occasions but also in items like strollers, jewelry, perfumes, diapers, nail polish, hair dye, elaborate birthday cakes, and designer shoes, all coupled with access to “gold standard” veterinary care.

Research indicates that fur babyism negatively impacts both physical and psychological health. For example, while strollers may assist injured or arthritic pets, excessive use for otherwise healthy dogs can result in muscle atrophy, joint issues, and obesity. Limiting a fur baby’s mobility curtails their instinct to explore, mark territory, and interact with their environment, which can lead to anxiety and fear.

Given these potential risks, one might expect the veterinary community to collectively oppose the fur baby trend. Surprisingly, this isn’t always the case. There’s a shift from outright condemnation to capitalizing on it, which is concerning. Encouraging excessive treatments, like radiotherapy for older animals, can further jeopardize animal welfare without necessarily enhancing health.

A pet owner’s affection is commendable as long as it prioritizes the animal’s well-being, ensuring they are free from pain and suffering. However, veterinarians who exploit an owner’s misplaced affection for profit through unnecessary, invasive, and costly tests and procedures lack ethical justification.

All caregivers should contemplate the distress caused by misclassifying an animal’s needs—treating them as a human child rather than as a pet. Veterinarians who cater to the fur baby trend ought to know better.

Where Did You Store It? Losing the Crucial Encryption Key Could Nullify the Election.

Feedback A weekly column filled with strange stories, unbelievable marketing claims, and perplexing instructions.

Locked Out

Feedback believes that the expression “couldn’t make up for it” is frequently misinterpreted. This doesn’t imply a limit to creativity; rather, it signifies that some developments can’t fit into a fictional narrative because people insist, “That will never happen.” The issue is, those individuals are mistaken, as reality can be quite absurd.

One of the key organizations in cryptography is the International Association for Cryptographic Research. This non-profit organization is committed to advancing cryptographic science. Recently, the IACR held elections for new officers and board directors while also adjusting its bylaws. They executed this ingeniously, leveraging their expertise as cryptographers. They utilized an online voting platform called Helios, promising “verifiable online elections.”

Helios is remarkably efficient. Every vote is recorded, ensuring that your vote is counted and remains unchanged. Tampering is thus rendered impossible. Simultaneously, every vote is kept confidential. The system employs advanced encryption technology, where all encrypted votes are compiled into an encrypted tally, and only the tally is decrypted.

But how is this tally decrypted? An organization has to appoint multiple directors. The IACR chose three individuals, each granted one-third of the cryptographic keys. All three needed to enter their portions of the keys to decipher the tally and view the results. This was a complete process—partial decryption wasn’t an option.

Then the expected occurred. “Unfortunately, one of the three trustees lost their private key irretrievably, an honest but unfortunate mistake, and as a result, we are unable to compute the decryption share.” I wrote to the IACR on November 21st. “Consequently, Helios was unable to finalize the decryption process, making it technically impossible to obtain or verify the election’s final outcomes.”

The IACR was compelled to: void the elections and restart the entire process. They now plan to “implement a two-out-of-three threshold mechanism for managing private keys and distribute clear written procedures for all trustees to follow before and during elections.” Feedback is eager to scrutinize that “documented procedure” even if its sole instruction is “Remember” in large bold letters on the cover page.

We are also intrigued by how what the IACR calls “human error” can undermine even the most meticulously designed systems. Each time a Silicon Valley entrepreneur speaks of the imminent emergence of human-level artificial intelligence, we internally cringe. The first iteration of such AI will probably align with the average human’s capabilities.

Floating Like a Raisin

The creativity of science journalists in coming up with new and engaging units of measure is always impressive. On November 17th, New York Times featured a story about “a small radio-frequency tag powered by solar energy that weighs just 60 milligrams and retails for $200.” Entomologists utilize this tag to monitor monarch butterflies during their migration across North America.

Anthony Weaver highlighted a sentence aimed at illustrating how heavy the tag is compared to the butterfly. “Most monarchs weigh between 500 and 600 milligrams, meaning each tagged transcontinental traveler is like half a raisin carrying three grains of uncooked rice.”

In the feedback section, we can all agree that this explanation is far clearer than stating “about 1/10 of body weight” could manage. Or as Anthony phrased it, “When I envisioned myself as a half-raisin on a cross-continental trek with rice to Mexico, I genuinely grasped how butterflies relate to science.”

No, this is not a call for you to submit similar examples from your page. New Scientist. Don’t even think about it.

Boys Club

The reason you may not receive feedback on social media is simply because you lack the mental bandwidth to figure out how to stand out on six different platforms with entirely different algorithms. Nonetheless, we half-watch things, which is why I found the spontaneous experiment on LinkedIn intriguing. Women in the field altered their names and pronouns to appear male, resulting in a spike in engagement.

For instance, social media consultant Simone Bonnet observed a 1600 percent rise in profile views after changing her pronouns to “he/him” and her name to “Simon E.” According to The Guardian, others experienced similar increases. Meanwhile, Daniel Hyers, who possesses an ideal LinkedIn name, attempted the reverse by “changing his name to Daniela for 4 days.” Day 1: a -26% drop.”

Sakshi Jain from LinkedIn stated that feedback indicates the platform’s “algorithms and AI systems are not utilized.” Demographic data (age, race, gender, etc.) are factored in as signals to assess the visibility of content, profiles, and posts in users’ feeds. We don’t dispute that, but we also theorize that unintended emergent outcomes play a significant role. Algorithm bias.

Meanwhile, Feedback is in the midst of creating a new LinkedIn page, which we will dub Mansplaining.

Top 6 Sci-Fi Series to Watch in 2025

In “Common Side Effects” Marshall makes an important discovery

Warner Bros. Discovery

2025 has brought many captivating sci-fi shows showcasing themes of chaos, intrigue, and resistance. This unrest may mirror our world’s current state, but it certainly has led to some incredible television. Here are six series you should consider adding to your watch list.

Two of the standout shows have returned with new seasons. Initially, when Andor (Disney+) premiered in 2022, it felt somewhat unreal. Was it just a fun ride for both loyal fans and newcomers? A prequel focusing on Rebel Alliance spy Cassian Andor, written and performed with Shakespearean intensity? The question lingered in my mind.

However, it truly is fantastic. Remarkably, the second and final season (sadly) of Andor is even better than the first. Now centered on the battle against the Galactic Empire, Cassian, under the direction of a shadowy spymaster Lusen, steals a ship to rescue operatives, amidst a larger conflict. A timely and beautifully narrated tale amidst an era of rising authoritarianism, Andor undoubtedly stands out as the year’s finest show.

Another worthy contender from 2022 is Severance (Apple TV), which presents a starkly different set of rebels. Nestled within the enigmatic Lumon Industries, it showcases employees who opt for “separation.” Their professional memories are cut off from their true selves, generating a new entity known as “innie,” who knows nothing outside their work existence.


The instability present in numerous 2025 sci-fi series negatively portrays our reality, yet translates into remarkable television.

These innies endure relentless horrors orchestrated by Lumon’s middle management, while the “outies” who cast them into this predicament remain blissfully unaware. Their only escape? Resigning to death. The second season takes a spine-chilling turn, unveiling deeper aspects of Lumon’s bizarre operations. Severance is a thoroughly satisfying mystery, intelligently unraveling its plot while adequately addressing the intricacies behind it.

James Marsden as President Cal Bradford in Paradise

Disney Copyright: Disney/Brian Roedel

Now, let’s talk about shows that may seem ordinary at first glance. New Scientist suggests Paradise (Disney+/Hulu), which skyrocketed to popularity in January. Initially a standard political thriller, the casting of Sterling K. Brown as U.S. secret agent Xavier Collins and James Marsden as Cal Bradford, a suspected presidential murderer, proves clever. Their on-screen chemistry is outstanding, and the fast-paced plot keeps viewers guessing.

What seemed like a light binge-watch took a captivating turn towards sci-fi by the end of an unforgettable first episode. Paradise brilliantly transitions from mere entertainment to something truly engaging. Without giving away spoilers, it casts an eerie shadow over the investigation, preventing the narrative from spiraling into absurdity. Absurdity is present—many pivotal moments are underscored with airy renditions of 1980s power ballads—but it’s just the right touch.

Every year, numerous end-of-the-world narratives unfold on screens, but inevitably, some stand out more than others. Among the top shows of 2025 is El Eternaut (Netflix), which breathes life into the classic comic by Héctor Germán Oesterheld.

As heavy snow descends upon Buenos Aires, former soldier Juan Salvo dons a gas mask and waders, venturing out to locate his family. It quickly becomes clear that the snowfall is just the tip of the iceberg. Juan and other survivors must unravel the mystery of what’s happening and how to thwart it.

Delve into the grim historical backdrop of Argentina’s late 1970s military dictatorship and the assassination of Oesterheld. El Eternaut pays appropriate homage to its source material, crafting a haunting series. One of the standout scenes this year takes place in a confined apartment where survivors must huddle together and strip Juan’s clothing, realizing their survival relies on outside elements.

If you lean towards warmer dystopian narratives, consider Pluribus (Apple TV), written by Breaking Bad’s Vince Gilligan. Set against the backdrop of sunny New Mexico, it follows the tale of jaded romance novelist Carol Starka, who is anything but a hero. In a world where most of humanity becomes overwhelmed by a sudden wave of happiness, everyone clamors to serve Carol, one of the few unaffected individuals.

What if a utopia existed, but not all could bask in its light? Carol is uninterested in participating in this enforced joy, yet discovering a path to normalcy proves challenging, especially considering how lovely a world free of conflict and selfishness can be.

Pluribus exhibits excruciating confidence and leads you through unexpected twists, anchored by an impressive central performance.

Surprises Await

Let’s shift to a more uplifting topic about joy. Common Side Effects (Channel 4/Cartoon Network) has been the biggest surprise for me this year, not just for its quality—thanks to co-creator Joe Bennett, known for the remarkable Scavenger’s Rain—but because it garnered enough viewers to warrant a second season.

This animated series follows fungi expert Marshall, who stumbles upon a shocking finding—a mushroom that seems to possess the power to cure various ailments. Unsurprisingly, this mushroom, dubbed Blue Angel, quickly becomes a sought-after commodity that nefariously falls into the hands of Leutical Pharmaceuticals, a company whose newest employee is Frances, a childhood friend recently reconnected with Marshall.

With enemies in pursuit, the show transcends mere conspiracy thriller tropes or critiques of Big Pharma. Common Side Effects weaves a thoughtful, engaging narrative about envisioning a brighter future. Let’s take inspiration from this for 2026.

Volcanic Eruptions Could Have Triggered the Black Death’s Arrival in Europe

Bubonic plague entered Europe in the late 1340s.

CPA Media / Alamy

The Black Death, a devastating outbreak of bubonic plague that decimated up to 60 percent of medieval Europe’s population, may have been triggered by volcanic eruptions around 1345.

The bacterium responsible for the plague is Yersinia pestis, transmitted by fleas that infest rodents and infect humans through bites. The origin of the 14th-century epidemic in Europe remains unclear, though historical accounts indicate that grain shipments from the Black Sea to Italy could have played a role.

“The Black Death was pivotal in the Middle Ages, and we sought to understand why such immense quantities of grain were transported to Italy, particularly in 1347,” states Martin Bauch of the Leibniz Institute for the History and Culture of Eastern Europe, Germany.

To explore this, Bork and his colleagues, including Wolf Bungen from the University of Cambridge, examined climate data stemming from tree rings, ice cores, and historical accounts.

Reports from Japan, China, Germany, France, and Italy revealed a decline in sunlight and an increase in cloud cover from 1345 to 1349, likely due to a sulfur-rich volcanic eruption or multiple eruptions in an unidentified tropical region, according to Bauch and Büngen.

Data from Greenland and Antarctica’s ice cores and thousands of tree-ring samples across eight native European areas indicate significant climate shifts may have occurred during this period.

Moreover, researchers uncovered records showing that Italian officials, faced with famine due to harsh weather and poor harvests, took preemptive measures in 1347 to import grain from the Mongols of the Golden Horde near the Sea of Azov.

“They operated with exceptional professionalism and efficiency to mitigate soaring prices and impending starvation through grain imports before hunger led to mortality,” Bauch explained. “As these societies had effective famine-response strategies, the plague bacterium likely traveled alongside the grain.”

During that era, the causes of the plague were shrouded in mystery, with many attributing the outbreak to “astral alignments and toxic vapors emitted by earthquakes.”

Though the plague might have eventually invaded Europe, Bauch suggests the population decline would have been less severe without this proactive approach. “My point isn’t against preparedness but rather to highlight that successful measures in one area can inadvertently create challenges in others.”

Aparna Lal, a researcher at the Australian National University in Canberra, asserts that a “perfect storm of conditions” likely facilitated the Black Death’s arrival in Europe. “Rising food prices, well-documented hunger issues, and colder, wetter climates could have impaired immune defenses due to nutritional deficiencies and behavioral changes, including increased indoor congregation,” she says.

However, she notes that further research is necessary to clarify cause-and-effect dynamics. “The immediate disturbances caused by the eruptions seem to have significantly influenced local weather patterns, but, as mentioned previously, additional evidence is essential to confirm their role in the Black Death’s entry into Europe,” Lal emphasizes.

Job Crisis: The Impact of Large Data Centers on Australia’s Freshwater Resources

a■ Australia is capitalizing on the AI boom, with numerous new investments in data centers located in Sydney and Melbourne. However, experts caution about the strain these large-scale projects may impose on already limited water resources.

The projected water demand for servicing Sydney’s data centers is anticipated to surpass the total drinking water supply in Canberra within the next decade.

In Melbourne, the Victorian government has pledged a $5.5 million investment to transform the city into Australia’s data center hub. Currently, hyperscale data center applications already exceed the collective water demands of nearly all of the top 30 business customers in the state.

Tech giants like Open AI and Atlassian are advocating for Australia to evolve into a data processing and storage hub. With 260 data centers currently operational and numerous others planned, experts express concern regarding the repercussions for drinking water resources.

Sydney Water projects that it will require as much as 250 megalitres daily to support the industry by 2035—more than the total drinking water supply in Canberra drinking water).

Cooling Requires Significant Water

Professor Priya Rajagopalan, director of RMIT’s Center for Post Carbon Research, points out that a data center’s water and energy requirements are largely dictated by the cooling technology implemented.

“Using evaporative cooling leads to significant water loss due to evaporation, while a sealed system conserves water but requires substantial amounts for cooling,” she explains.

Older data centers typically depend on air cooling. However, the increased demand for computational power means greater server rack densities, resulting in higher temperatures. Hence, these centers rely more heavily on water for cooling solutions.

Water consumption in data centers varies significantly. For instance, NextDC has transitioned to liquid-to-chip cooling, which cools processors and GPUs directly, as opposed to cooling entire rooms with air or water.

NextDC reports that while initial trials of this cooling technology have been concluded, liquid cooling is far more efficient and can scale to ultra-dense environments, improving processing power without a proportional increase in energy consumption. Their modeling suggests that the power usage efficiency (PUE) could decline to as low as 1.15.

Subscribe to Climate and Environment Editor Adam Morton’s Clear Air column for free!

The data center sector measures its sustainability using two key metrics: water usage efficiency (WUE) and power usage efficiency (PUE). These metrics gauge the levels of water or power consumed per unit of computing work.

WUE is calculated by dividing annual water usage by annual IT energy usage (kWh). For instance, a 100MW data center that uses 3ML daily would yield a WUE of 1.25. A number closer to 1 indicates greater efficiency. Certain countries enforce minimum standards; for example, Malaysia recommends a WUE of 1.8.

Even facilities that are efficient can still consume substantial amounts of water and energy at scale.

NextDC’s last fiscal year’s PUE stood at 1.44, up from 1.42 the previous year. The company indicates that this reflects the changing nature of customer activity across its facilities and the onboarding of new centers.

Calls to Ban Drinking Water Usage

Sydney Water states that estimates regarding data center water usage are continually reassessed. To prepare for future demands, the organization is investigating alternative, climate-resilient water sources like recycled water and rainwater harvesting.

“Every proposed connection for data centers will undergo case-by-case evaluations to guarantee adequate local network capacity. If additional services are necessary, operators might need to fund upgrades,” a Sydney Water representative said.

In its submission to the 2026-2031 rate review in Victoria, Melbourne Water observed that hyperscale data center operators seeking connectivity “expect instantaneous and annual demand to surpass nearly all of Melbourne’s leading 30 non-residential customers.”

Melbourne Water mentioned, “This has not been factored into our demand forecasting or expenditure plans.”

The agency is requesting upfront capital contributions from companies to mitigate the financial burden of necessary infrastructure improvements, ensuring those costs do not fall solely on the broader customer base.

Documents show that Greater Western Water in Victoria has received 19 data center applications. See more from ABC provided to the Guardian.

The Concerned Waterways Alliance, composed of various Victorian community and environmental organizations, has expressed concerns regarding the potential diversion of drinking water for cooling servers when the state’s water supplies are already under stress.

Alliance spokesperson Cameron Steele emphasized that expanding data centers would create a greater reliance on desalinated water, thereby diminishing availability for ecological streams and possibly imposing costs on local communities. The group is advocating for a ban on potable water usage for cooling and demanding that all centers transparently report their water consumption.

“We strongly promote the use of recycled water over potable water within our data centers.”

Closed Loop Cooling

In hotter regions, like much of Australia during summer, data centers require additional energy or water to remain cool.

Daniel Francis, customer and policy manager at the Australian Water Works Association, highlights that there is no universal solution for the energy and water consumption of data centers, as local factors such as land availability, noise restrictions, and water resources play significant roles.

“We constantly balance the needs of residential and non-residential customers, as well as environmental considerations,” says Francis.

“Indeed, there is a considerable number of data center applications, and it’s the cumulative effect we need to strategize for… It’s paramount to consider the implications for the community.”

“Often, they prefer to cluster together in specific locations.”

One of the data centers currently under construction in Sydney’s Marsden Park is a 504MW facility spanning 20 hectares with six four-story buildings. The company claims this CDC center will be the largest data campus in the southern hemisphere.

Last year, CDC operated its data centers with 95.8% renewable electricity, achieving a PUE of 1.38 and a WUE of 0.01. A company representative stated that this level of efficiency was made possible through a closed-loop cooling system that does not require continuous water extraction, in contrast to traditional evaporative cooling systems.

“CDC’s closed-loop system is filled only once at its inception and functions without ongoing water extraction, evaporation, or waste generation, thereby conserving water while ensuring optimal thermal performance,” the spokesperson noted.

“This model is specifically designed for Australia, a nation characterized by drought and water shortages, focusing on long-term sustainability and establishing industry benchmarks.”

Despite CDC’s initiatives, community concerns regarding the project persist.

Peter Rofile, acting chief executive of the Western NSW Health District, expressed in a letter last June that the development’s proximity to vulnerable communities and its unprecedented scale posed untested risks to residents in western Sydney.

“This proposal does not guarantee that this operation can adequately mitigate environmental exposure during extreme heat events, potentially posing an unreasonable health risk to the public,” Rofile stated.

Is “Brain Rot” a Reality? Researchers Highlight Emerging Risks Linked to Short-Form Videos

Short-form videos are dominating social media, prompting researchers to explore their impact on engagement and cognitive function. Your brain may even be changing.

From TikTok to Instagram Reels to YouTube Shorts, short videos are integral to platforms like LinkedIn and Substack. However, emerging research indicates a link between heavy short-form video consumption and issues with concentration and self-control.

The initial findings resonate with concerns about “brain rot,” defined by Oxford University Press as “the perceived deterioration of a person’s mental or intellectual condition.” This term has gained such popularity that it was named the word of the year for 2024.

In September, a review of 71 studies found that extensive short-form video use was correlated with cognitive decline, especially in attention span and impulse control, involving nearly 100,000 participants. Published in the American Psychological Association’s Psychological Bulletin, this review also connected heavy consumption to heightened symptoms of depression, anxiety, stress, and loneliness.

Similarly, a paper released in October summarized 14 studies that indicated frequent consumption of short-form videos is linked to shorter attention spans and poorer academic performance. Despite rising concerns, some researchers caution that the long-term effects remain unclear.

James Jackson, a neuropsychologist at Vanderbilt University Medical Center, noted that fear of new technologies is longstanding, whether regarding video games or iconic concerts. He acknowledges legitimate concerns but warns against overreacting. “It’s naive to dismiss worries as just grumpy complaints,” he said.

Jackson emphasized that research indicates extensive short-form video consumption could adversely affect brain function, yet further studies are needed to identify who is most at risk, the long-lasting impact, and the specific harmful mechanisms involved.

ADHD diagnoses in the U.S. are on the rise, with about 1 in 9 children diagnosed by 2022, according to the CDC. Keith Robert Head, a doctoral student at Capella University, suggests that the overlap between ADHD symptoms and risks from short videos deserves attention. “Are these ADHD diagnoses truly ADHD, or merely effects of short video use?” he questioned.

Three experts noted that research on the long-term effects of excessive short-form video use is in its early stages, with international studies revealing links to attention deficits, memory issues, and cognitive fatigue. However, these studies do not establish causation, often capturing only a snapshot in time.

Dr. Nidhi Gupta, a pediatric endocrinologist focused on screen time effects, argues that more research is necessary, particularly concerning older adults who may be more vulnerable. Gupta cautions that cognitive changes associated with short-form media may lead to a new addiction, likening it to “video games and TV on steroids.” She speculated that, just as research on alcohol and drugs took decades to evolve, a similar moral panic around short videos could emerge within the next 5 to 10 years.

Nevertheless, Jackson contends that short-form videos can be beneficial for online learning and community engagement: “The key is balance. If this engagement detracts from healthier practices or fosters isolation, then that becomes a problem.”

Irish Authorities Request Microsoft to Investigate Alleged Illegal Data Processing by IDF

Irish officials have received a formal request to look into Microsoft regarding claims of unlawful data processing by the Israel Defense Forces.

The Irish Council for Civil Liberties (ICCL), a human rights organization, filed the complaint with the Data Protection Commissioner, who is legally charged with overseeing all data processing activities within the European Union.

This comes after reports in August from the Guardian, along with Israeli-Palestinian publication +972 Magazine and Hebrew media Local Call, highlighted that substantial amounts of Palestinian phone communications were stored on Microsoft’s Azure cloud platform as part of an extensive surveillance initiative by the Israeli military.

The ICCL asserts that the handling of personal data “aided in the commission of war crimes, crimes against humanity, and genocide by Israeli forces.” Microsoft’s European headquarters are located in Ireland.

“Microsoft’s technologies are endangering millions of Palestinians. These are not just theoretical data protection issues,” said Joe O’Brien, executive director of ICCL.

He remarked that cloud services “enable tangible violence” and emphasized the need for the “DPC to respond swiftly and decisively” given the “risk to life involved in the matter at hand.”

He further stated, “When European infrastructure is used to facilitate surveillance and targeting, the Irish Data Protection Commissioner must step in and utilize its full authority to hold Microsoft accountable.”

A collection of leaked documents reviewed by the Guardian has indicated that as early as 2021, the Israeli military’s intelligence unit, Unit 8200, started discussions to transfer large amounts of classified intelligence data to a cloud service operated by a US company.

The documents revealed that Microsoft’s storage facilities were employed by Unit 8200 to archive extensive records of Palestinian daily communications, which facilitated specific airstrikes and other military actions.

Following this revelation, Microsoft initiated an urgent external inquiry into its connections with Unit 8200. Preliminary findings led the company to suspend this unit’s access to certain cloud storage and AI services.

ICCL contends that Microsoft played a crucial role in enabling Israel’s military surveillance system known as “Al-Minasek.”

The organization claims that records of intercepted conversations between EU servers and Israel were reportedly “deleted,” obstructing evidence of unlawful processing before an EU inquiry could commence, violating the EU’s General Data Protection Regulation (GDPR) that regulates personal data usage.

With Azure’s vast storage and computational capabilities, Unit 8200 was establishing an indiscriminate system allowing agents to collect, replay, and analyze cell phone calls from entire populations.

A spokesperson for the DPC stated, “We can confirm that the DPC has received the complaint and is currently evaluating it.”

Microsoft has been approached for a response.

Porn Company Fined £1 Million by Ofcom for Inadequate Age Verification

A pornography company managing 18 adult websites has incurred a £1 million fine from the regulatory body Ofcom for inadequate age verification measures, marking the largest penalty issued thus far under the UK’s Online Safety Act.

The Belize-based AVS Group has also faced an additional fine of £50,000 for not adhering to information request protocols.

This incident represents the third time the communications regulator has enforced fines on a company regarding the UK’s Online Safety Act, which implemented stringent age verification rules in July.

AVS has implemented what it describes as an age verification system; however, regulatory assessments have deemed it to be ineffective.

The company finds itself facing a £1,000 penalty for each day Ofcom considers the circumstance valid within a 72-hour window of the age check being introduced. This leads to a cumulative fine of £300 daily until they comply with the information request or for as much as 60 days.

Since the implementation of the new regulations, Ofcom has initiated investigations into 92 online services, giving priority to sites attracting millions of monthly visitors, considering the potential harm these sites pose.

Oliver Griffiths, Ofcom’s group director for online safety, shared with BBC Radio 4’s Today program that the fines are part of a “broader shift” focused on platform accountability, which includes the “large scale” rollout of age verification on adult sites to combat child sexual abuse material.

Mr. Griffiths noted that more than 90 websites, inclusive of 83 adult sites, are still under scrutiny for possible infringements of the law, and further penalties are expected.

Ofcom also indicated that a significant social media platform, unnamed, could face formal repercussions should it fail to enhance its compliance measures. This platform has reportedly provided insufficient risk assessments needed to evaluate the potential appearance of illegal content, such as scams and unlawful pornography, to its users.

“We reached back out to inform them a re-evaluation was necessary,” Griffiths stated. “Should they fail to treat this matter with due seriousness again, we will promptly escalate to enforcement.”

Furthermore, Ofcom disclosed its review of major anonymous platforms’ capabilities to eliminate illegal terrorist and hate-driven content, including anti-Semitic and anti-Muslim material, with possible enforcement actions on the horizon.

The Online Safety Act brings forth several new regulations designed to shield children and adults from harmful content, with violations potentially costing up to £18 million or 10% of annual UK revenue, or even business closures.

More than half of the UK’s 100 most frequented adult services have instituted age verification since the rule changes in July, alongside social media sites like X, TikTok, and Reddit, according to the regulator. Mr. Griffiths acknowledged a rapid increase in the usage of virtual private networks (VPNs), which enable users to bypass regional restrictions on certain sites, noting that this number had peaked at between 600,000 to over 1 million users when the age verification was assessed but has since declined “significantly” below 1 million.

“There has been a slight uptick in VPN usage; however, several elements were not sold wholesale. Interesting research …indicates that children do not seem to constitute a large proportion,” he noted.

Technology Secretary Liz Kendall stated: “Since the Online Safety Act was enacted, platforms are indeed beginning to accept responsibility for safeguarding children and eradicating illegal and hateful content.”

“Ofcom has the full backing of the Government and is leveraging every authority at its disposal to ensure a service prioritizing user safety. Ensuring the online safety of children remains a top priority for this Government and for me personally.”

Human Cloning: Are the Ultra-Wealthy Engaging in Secret Experiments?

Is it conceivable that the ultra-wealthy are covertly cloning humans?

Juan Lovaro/Shutterstock

Throughout my extensive career reporting on extraordinary breakthroughs in biology, I’ve observed numerous concepts gaining massive attention, receiving thorough media scrutiny for years, and later fading from the public consciousness. Take, for instance, human cloning.

Following the landmark birth of Dolly the sheep in 1997—the first cloned mammal—speculation soared about the potential for human cloning. There were even some implausible claims about human clones existing. Yet, in recent years, such fervor has significantly diminished.

Nonetheless, reproductive technologies have evolved remarkably since the 1990s. Notably, just six years after CRISPR was unveiled, the world saw the first unlawful creation of a gene-edited child. This raises questions about what might be occurring behind closed doors. Are human clones already out there, undetected? Of course, identical twins don’t count.

What could motivate someone to engage in this? Recently, in a discussion between Vladimir Putin and Xi Jinping, the topic of extending life via organ transplants emerged. The most effective method could involve cloning individuals for organ harvesting, thereby eliminating the common issue of immune rejection often depicted in science fiction narratives. Consider Island or the book Never Let Me Go.

Moreover, cloning brings forth the notion of creating a duplicate of a person, offering a semblance of immortality, as illustrated in the television series Foundation, where the empire is governed by successive clones. However, our experiences with identical twins tell us that sharing the same genome does not equate to being the same person. As shown by Tatiana Maslany in the series Orphan Black, each clone evolves into a distinct individual. Nevertheless, wealthy individuals can hold irrational beliefs similar to others and often display a particular desire to extend their lifespans.

For scientists, there’s also the allure of being the first to achieve a groundbreaking feat. A report from a Chinese commission determined that the creators of CRISPR children “conducted research illegally in pursuit of personal fame and profit.”

Goals of Therapeutic Cloning

So, could human clones exist? For many years, the notion of cloning mammals was deemed unfeasible. Early embryo cells have the ability to differentiate into any bodily part but quickly become specialized—a process previously thought irreversible.

Dolly’s existence disproved that theory. She was produced by fusing cells from an adult ewe’s udder with a DNA-depleted egg. Her announcement in February 1997 led to a frenzy of attempts to generate cloned human embryos. The objective wasn’t to create cloned infants, but rather to harvest embryonic stem cells for novel medical therapies. As cloned cells are a perfect match for an individual, they could theoretically be employed to produce replacement tissues and organs with no risk of immune rejection.

However, extracting stem cells from cloned human embryos has proven more challenging than anticipated. It wasn’t until 2004 that Hwang Woo-seok claimed success. At that time, I found his paper impressive, as it addressed all conceivable objections effectively. Unfortunately, the study was later revealed to be fraudulent, resulting in its retraction. This experience remains ingrained in my memory. Nowadays, whenever a thesis appears too good to be true, my initial instinct is to be skeptical.

Ultimately, true embryonic stem cells from cloned human embryos weren’t obtained until 2013. By then, alternative methods for generating compatible stem cells through the activation of specific genes had emerged, leading to a decline in interest in therapeutic cloning.

Cloned Pets and Other Animals

Conversely, animal cloning has become increasingly established. Occasionally, headlines emerge when celebrities disclose that they’ve cloned their pets. Recently, former NFL player Tom Brady made news by revealing that his dog is a clone, produced by a company acquired by Colossal Biosciences.

Apart from serving as a way to “revive” cherished pets, cloning is also utilized in agriculture and horse breeding. For instance, male horses are often castrated, meaning that if they excel in show jumping, the only method to utilize their genetic material for future breeding is through cloning.

Nonetheless, animal cloning continues to pose significant challenges. A 2022 study of the first 1000 dog clones found that the cloning process is still highly inefficient, with merely 2 percent of implanted cloned embryos resulting in live births. This inefficiency contributes to the high cost of pet cloning, around $50,000.

Moreover, about 20% of cloned dogs presented noticeable physical anomalies, including enlarged tongues, unusual eye colors, cleft palates, and excessive muscle mass. Some male dog clones even exhibited female physical traits.

But what if the wealthy and powerful could clone themselves, unburdened by such concerns?

Challenges in Adult Cloning

Multiple sources have indicated several successful monkey cloning endeavors since 2017, suggesting potential applicability for humans as well. However, these sources often fail to mention that all these primate clones have been derived from fetal cells, not adult ones.

The crux of the issue lies in the fact that reprogramming adult cells to mimic a fetal state is far more complex than reprogramming fetal cells. To me, cloning signifies creating a genetically identical replica of an adult, which is what made Dolly’s achievement exceptional.

In essence, I remain convinced that cloning an adult is still unattainable. In a world filled with dictators and eccentric billionaires, this might be a fortunate circumstance.

Tigers Seems to Be Making a Comeback in Sumatra’s Isolated Jungles

Camera trap photo of a Sumatran tiger in the Leuser Ecosystem, Indonesia

Figel et al. 2025, BKSDA-Aceh, DLHK

Camera trap studies have discovered over double the count of endangered Sumatran tigers compared to those recorded on other Indonesian islands, signaling a positive outcome for conservation initiatives.

The Sumatran tiger represents the last surviving population of the subspecies panthera tigris sondaica, one of the two subspecies of tigers.

Collaborating with the Gayo indigenous community, researchers positioned 60 camera traps on trees within a previously unexplored area of the Leuser ecosystem on Sumatra, one of Southeast Asia’s largest remaining rainforests.

These traps captured images of 17 tigers over 90 days in 2023 and 18 in 2024, in stark contrast to earlier 90-day assessments in Sumatra, which reported an average of seven tigers. The survey documented 14 adult female tigers, 12 males, three cub pairs, and one tiger of unknown gender.

“This surpassed my expectations because previous research indicated that tigers wouldn’t be found in such densities,” stated Joe Figel from the conservation group Hutan Harimau. “This is a very promising finding and highlights the significant conservation efforts in this region.”

Sumatran tigers face threats such as poaching for trophies and traditional medicine, alongside logging activities depleting their vital dipterocarp tree habitats. Due to insufficient data, estimates for their population range from 173 to 883.

While a 90-day period was utilized for initial comparisons, researchers ultimately extended their study to 180 days in both 2023 and 2024, delivering a more comprehensive seasonal record, noted Deborah Marter from Flora and Fauna International, who was not a part of the study.

The unexpectedly high tiger population in the Leuser Ecosystem indicates that the lowland forests are abundant in prey, particularly sambar deer, according to Figel. It also implies that monthly ranger patrols are effective in curbing poaching activities.

Located near Gunung Leuser National Park, the study area is overseen by rangers funded by the NGOs Forum Conservasi Roussel and Hutan Harimau, in partnership with the Environment and Forestry Department of the previously conflict-affected Aceh region.

However, research indicates a need for additional ranger support. Recently, tigers have vanished from Vietnam, Cambodia, and Laos.

“Do we need any further warning signs?” asks Figel. “Tiger populations throughout Southeast Asia are facing a critical crisis.”

Mars Was Once Warmer and Wetter, Say Planetary Scientists

NASA’s Perseverance spacecraft has identified thousands of light-toned rock fragments, also known as floating rocks, several of which exhibit spectral characteristics of an aluminum-rich clay mineral known as kaolinite. To understand their origins, planetary scientists utilized data from Perseverance’s SuperCam and Mastcam-Z instruments to analyze the chemistry and reflectance spectra of the floating rocks in relation to deeply weathered paleosols (ancient soils) and hydrothermal kaolin deposits recorded in Earth’s geological archives. The increased levels of aluminum and titanium, along with the reduced amounts of iron and magnesium, differentiate these rocks from hydrothermal deposits, aligning them more closely with the bleached layers of paleosoils formed during periods of significant rainfall in Earth’s past greenhouse climates. Thus, these rocks may signify some of the most aqueous periods in Mars’ history.

“Rocks like these are likely among the most significant outcrops we’ve observed from orbit because their formation is challenging to replicate elsewhere on Mars,” stated Dr. Bryony Hogan, Perseverance’s long-term planner and a researcher at Purdue University.

“Given that these require substantial water, we believe they could be indicative of an ancient, warmer, wetter climate that experienced prolonged periods of rainfall.”

“Tropical environments, such as rainforests, are where kaolinite clays are predominantly found on Earth,” added Adrian Broz, Ph.D., a postdoctoral researcher at Purdue University.

“Thus, when finding kaolinite on Mars, which is desolate and frigid with no surface liquid water, it suggests that there used to be significantly more water than is present today.”

Kaolinite fragments, varying in size from pebbles to larger rocks, contribute to the ongoing discussion about the climate of Mars billions of years ago.

Initial analyses using the SuperCam and Mastcam-Z instruments have involved comparing kaolinite to analogous rocks on Earth.

Debris from Mars could yield crucial insights into not only the planet’s historical environmental conditions but also how it transitioned to its current desolate state.

“Kaolinite carries its own enigmas,” emphasized Dr. Hogan.

“Currently, there are no significant outcrops nearby that could explain the presence of these light-colored rocks, despite their distribution along the mission’s path since Perseverance’s landing in Jezero Crater in February 2021.”

“This crater once housed a lake that was approximately twice the size of Lake Tahoe.”

“While there are compelling indicators of significant water events, the origin of these rocks remains uncertain.”

“It’s possible they were transported into the Jezero lake by rivers that formed the delta regions, or they may have been ejected into Jezero by a meteorite impact. The complete picture is still unclear.”

Satellite imaging has revealed substantial kaolinite outcrops in various regions of Mars.

“However, until we can physically reach these large outcrops with spacecraft, these small rocks are the only tangible evidence we have regarding their formation,” Dr. Hogan noted.

“Currently, the findings in these rocks suggest a historically warmer and wetter environment.”

The researchers compared the Martian kaolinite samples studied by Perseverance to rock samples located near San Diego, California, and in South Africa. The similarities between the rocks from both planets were striking.

On Earth, kaolinite forms in both rainy tropical climates and hydrothermal systems where hot water permeates into rocks.

Nonetheless, this process leaves behind chemical signatures that differ from the effects of cold leaching from rain over extended periods.

Scientists evaluated various hydrothermal leaching scenarios against Martian rocks using datasets from three distinct sites.

Rocks like kaolinite from Mars act as time capsules, potentially preserving billions of years of information regarding environmental conditions throughout Earth’s history.

“All life requires water, so if these Martian rocks signify a rainfall-driven environment, that’s an extraordinary indication of a potentially habitable space where life could have flourished on Mars,” stated Dr. Broz.

The team’s paper has been published in the journal Communication Earth and Environment.

Psyche Captures Sight of Interstellar Comet 3I/ATLAS

NASA’s Psyche spacecraft has obtained fresh images of 3I/ATLAS, marking it as the third astronomical object and the second comet observed from outside our solar system.



Psyche secured four observations of 3I/ATLAS over an 8-hour period on September 8 and 9, 2025. Image credit: NASA/JPL-Caltech/ASU.

3I/ATLAS was found on July 1, 2025, by the ATLAS survey telescope located in Rio Hurtado, Chile.

The orbits of interstellar comets represent the most dynamically extreme pathways of any astronomical object recorded within our solar system.

Known also as C/2025 N1 (ATLAS) and A11pl3Z, 3I/ATLAS reached its closest point to the Sun on October 30, 2025.

The latest images of the comet were captured during an eight-hour window on September 8 and 9, 2025, when 3I/ATLAS was roughly 53 million kilometers (33 million miles) away from NASA’s Psyche spacecraft.

“The observations collected by the mission’s multispectral imager will assist in refining the trajectory of 3I/ATLAS,” stated members of the Psyche team.

“Psyche’s multispectral imager consists of a pair of identical cameras fitted with filters and telephoto lenses to photograph the surface of the metal-rich asteroid Psyche across various wavelengths of light.”

“During these observations, Comet 3I/ATLAS was moving away from the spacecraft, but the imager’s sensitivity to the comet’s reflected sunlight allowed for accurate tracking of the object.”

The recent observations further illuminate the faint coma—a cloud of gas and dust—surrounding 3I/ATLAS’ core, which is a frozen mixture of ice and rock.

“Psyche will collaborate with numerous other NASA missions to track the positions of comets over time, aiding astronomers in comprehending the movement of such objects within our solar system,” researchers stated.

“Though comets do not pose a direct threat to Earth, NASA’s space missions contribute to ongoing efforts to discover, monitor, and better understand objects in our Solar System.”

Scientists Uncover Alien Bioessential Sugars in Asteroid Bennu Samples

A collaborative effort by researchers from the U.S. and Japan examined extracts from near-Earth asteroid (101955) Bennu, gathered by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security Regolith Explorer) spacecraft, and uncovered several bioessential sugars, such as ribose (an RNA sugar) and glucose (a metabolic substrate).

This mosaic image of asteroid Bennu consists of 12 images collected by OSIRIS-REx’s PolyCam instrument on December 2, 2018 from a range of 15 miles (24 km). Image credit: NASA / NASA Goddard Space Flight Center / University of Arizona.

“The OSIRIS-REx mission successfully returned 121.6 g of regolith (unconsolidated granular material) from Bennu to Earth on September 24, 2023, under stringent conditions,” stated Yoshihiro Furukawa, a researcher at Tohoku University, along with his team.

“The samples were preserved in high-purity nitrogen at NASA’s Johnson Space Center.”

“Initial studies revealed that Bennu possesses mineralogical and elemental traits similar to carbonaceous chondrites, is enriched in carbon and nitrogen compared to most meteorites, but resembles ungrouped carbonaceous chondrites, and has undergone extensive aqueous alteration.”

“The analyzed samples from Bennu so far include soluble organic compounds like amino acids, amines, carboxylic acids, aldehydes, nucleobases, polycyclic aromatic hydrocarbons, and a diverse array of soluble molecules comprising carbon, hydrogen, nitrogen, oxygen, and sulfur.”

“We utilized this pristine asteroid material to investigate extraterrestrial bioessential sugars.”

The research team made a notable discovery of ribose, which contains five carbon atoms, and glucose, which has six, marking the first time these sugars have been identified in extraterrestrial samples.

While these sugars do not serve as direct evidence of life, their detection—along with previously identified amino acids, nucleobases, and carboxylic acids in Bennu samples—suggests that the fundamental building blocks of biomolecules were widely distributed throughout the solar system.

Furukawa et al. We discovered the essential sugars ribose and glucose in samples from the near-Earth asteroid Bennu collected by NASA’s OSIRIS-REx mission. Image credit: NASA / Goddard / University of Arizona / Dan Gallagher.

In Earth life, deoxyribose and ribose serve as critical components of DNA and RNA, respectively.

DNA is the primary vehicle for genetic information within cells. RNA, on the other hand, has various roles, and its presence is vital for life as we know it.

The ribose in RNA forms the sugar-phosphate “backbone” of the molecule, linking together nucleobases that carry genetic information.

“All five nucleobases that constitute DNA and RNA, along with phosphate, have already been identified in the Bennu samples brought back by OSIRIS-REx,” Dr. Furukawa noted.

“The recent discovery of ribose confirms that all elements required to form RNA molecules are present in Bennu.”

“Finding ribose in an asteroid sample is not unexpected.”

“Ribose has previously been found in two meteorites on Earth.”

“What’s significant about the Bennu sample is that researchers did not identify any deoxyribose.”

“If Bennu is indicative of conditions, it suggests that ribose may have been more abundant than deoxyribose in the early solar system environment.”

The researchers theorize that the detected ribose, along with the absence of deoxyribose, bolsters the RNA world hypothesis. This hypothesis posits that the first forms of life relied on RNA as the main molecule for storing information and facilitating the chemical reactions crucial for survival.

“Modern life relies on a complex system organized primarily by three types of functional biopolymers: DNA, RNA, and proteins,” Dr. Furukawa elaborated.

“However, early forms of life may have been simpler. RNA not only stores genetic information but can also catalyze numerous biological reactions, making it a strong candidate for the earliest functional biomacromolecule.”

“Bennu’s samples also contain glucose, a fundamental energy source for life on Earth, providing the first evidence that an essential energy source was present in the early solar system as well.”

a paper detailing these findings was published in this week’s edition of Nature Earth Science.

Upcoming Satellite Launch May Distort Hubble Space Telescope Images

Simulated representation of satellite trails contaminating images from future space telescopes

NASA/Boruff, Markham, Howell

Should space companies proceed with plans to deploy hundreds of thousands of satellites, up to a third of the images captured by the Hubble Space Telescope may be compromised.

In the last five years alone, over 75% of the approximate 14,000 satellites now orbiting Earth have been launched, many as part of megaconstellations, notably Elon Musk’s Starlink. Proposals indicate that we could see the deployment of as many as 500,000 satellites by the end of the 2030s, according to submissions to the US Federal Communications Commission (FCC).

Astronomers have long raised concerns regarding the potential impact of these satellites on ground-based telescopes. However, research by Alejandro Borlaf and his team at NASA’s Ames Research Center indicates that space telescopes are at risk as well.

“A telescope in space benefits from an unblemished environment; there’s no atmosphere or city lights,” Borlaf explains. “For the first time, we’re facing the issue of a man-made object contaminating our observations. This discovery was startling.”

By analyzing filings from the FCC and the International Telecommunication Union, Borlaf’s team estimated the anticipated number of satellites and their orbits over the next decade. They simulated the effect of these satellites blocking observations from four space observatories, including Hubble and China’s Shuntian telescope, as well as the Arrakis dark matter telescope set to launch in 2030, and the already launched SPHEREx galaxy telescope.

The researchers found that if 560,000 satellites are launched as projected, Hubble photos may capture an average of two satellite orbits, while Xuntian images could have approximately 90 satellite orbits due to a broader field of view and orbital altitude.

They validated their simulations by demonstrating that with the existing number of satellites, 4% of Hubble’s images would be influenced by the trajectories of these satellites, consistent with analyses of actual images.

These predictions could materialize if satellite launches proceed as planned. According to John Valentine from Dark Sky Consulting, a Tucson-based firm, it’s uncertain how many satellites will ultimately launch. “Many experts believe that over the next 15 years, the number of operational satellites could stabilize between 50,000 and 100,000.”

If the final number turns out to be only a fraction of the proposed figures, Valentine suggests, the impact on space telescopes would be notably reduced. “The number of trajectories per image would increase only slightly for ARRACHIS and Xuntian, while remaining relatively unchanged for SPHEREx and HST.”

How Dogs Can Enhance Our Consideration and Sociability by Altering Our Microbiome

Fetch! Dogs can enhance our happiness in various ways

Monica Click/Shutterstock

Dogs have long been celebrated as beloved companions. However, recent studies suggest they may also improve our well-being by influencing our microbiomes. Experiments conducted on mice indicate that dog owners possess unique bacterial species that promote both empathic and social behaviors.

It’s evident that pets significantly enhance life satisfaction while also impacting our gut microbiome. Research highlights how this microbiome affects our mental health and plays a role in shaping our personalities. With dogs often topping the list of preferred pets, Takefumi Kikusui and his team from Azabu University in Japan sought to investigate whether pets influence our microbiomes and enhance our overall well-being.

To delve into this, researchers analyzed a survey where caregivers of 343 adolescents aged 12 to 14 in Tokyo reported on their social behaviors, including feelings of loneliness, tendencies toward aggression, and peer interactions. It was noted that approximately a third of these adolescents own pet dogs.

Findings revealed that, on average, dog owners perceived themselves as less socially withdrawn and exhibited less aggressive tendencies compared to their non-dog-owning peers. The research team also examined potential influencing factors such as gender and household income.

Saliva samples indicated that several types of streptococcus bacteria were more abundant among adolescents who owned dogs, which is associated with lower levels of depressive symptoms.


“Engaging frequently with your dog exposes you to their microorganisms (like licking),” explains Gerald Clarke from University College Cork, Dublin, Ireland. These bacteria can migrate to the gastrointestinal tract, potentially causing infections. They can also produce anti-inflammatory substances like short-chain fatty acids, which may improve mental health.

An essential part of the study involved transplanting oral microbes from dog owners and non-dog owners into germ-free mice. Fecal analysis showed that the introduced microorganisms successfully colonized the mice’s intestines.

In subsequent weeks, the researchers conducted various behavioral tests on the mice. In one test, a mouse was placed in a cage alongside another mouse trapped in a tube. Results indicated that mice transplanted with microbes from dog owners were significantly more inclined to interact with the tube than those who received microbes from non-dog owners.

This behavior suggests that the original mice displayed greater empathy and a willingness to help, Kikusui noted. Recent research has also revealed that mice can assist their pregnant partners in giving birth and even provide rudimentary first aid.

In another experiment, dog-owner transplants exhibited a tendency to sniff unknown mice in their cages more frequently than the other groups, indicating increased sociability, according to Clarke. “Such social behaviors can have implications across species, including humans,” he asserts. “Robust social networks are beneficial for mental health; having limited social exposure can be detrimental.”

Gaining further insights into these microbial shifts and developing probiotics that replicate these effects could potentially benefit individuals without dogs, Clarke suggests. However, studies in other regions with different microbial exposures are necessary.

Experimental Vaccine Provides Year-long Protection Against Severe Allergy Attacks

Warning signs of food allergies and intolerances

Innovative vaccines may provide a new approach to combat severe food allergies

Researchers have developed an experimental vaccine that successfully protects mice from anaphylaxis, a potentially life-threatening allergic reaction, for at least one year. There is optimism that this vaccine will also be effective in humans.

Anaphylaxis poses a persistent threat to millions worldwide, particularly for individuals allergic to foods like peanuts and shellfish. In the UK alone, around 6% of adults, or about 2.4 million people, are believed to have clinically confirmed food allergies.

Allergic reactions can occur from consuming contaminated food or even from kissing someone who has recently eaten the allergenic food. This triggers a surge of immunoglobulin E (IgE) antibodies, leading to symptoms such as throat swelling, breathing difficulties, and a drop in blood pressure. Despite having an epinephrine auto-injector (like an EpiPen) at hand, many still need emergency treatment, and severe cases may be fatal.

Currently, avoiding allergens is the primary method of prevention, with limited alternatives available. Individuals can consider oral immunotherapy, where the allergen is gradually introduced under supervision to build up tolerance. There is also an anti-IgE monoclonal antibody drug, like omalizumab, which binds to IgE to block allergic responses. However, omalizumab is costly and requires injections every few weeks, sometimes indefinitely.

Recently, Laurent Reber and colleagues at the Toulouse Institute of Infection and Inflammation in France developed a vaccine named IgE-K. This vaccine encourages the immune system to produce antibodies that target IgE, preventing it from attaching to receptors on immune cells and averting severe allergic reactions.

“Our goal was to create a long-term solution, as individuals with food allergies face unintentional exposure at any time, necessitating ongoing protection,” says Reber.

In experiments with mice engineered to produce the human variant of IgE, the team discovered that two doses of the vaccine led to the generation of neutralizing antibodies against IgE.

“It blocks the molecules responsible for allergic reactions,” says Josh Koenig from McMaster University in Ontario, Canada.

Upon exposing the mice to a substance that triggered an allergic reaction, the unvaccinated mice experienced significant reactions, while the vaccinated mice exhibited no symptoms and were shielded from anaphylaxis for up to a year.

“It might last longer, but we have yet to conduct further testing,” noted Reber.

IgE forms part of the immune system, activated in response to toxins and certain intestinal parasites apart from allergens. “This mechanism is likely an evolutionary adaptation to combat toxins,” suggests Lever.

Lever asserts there is strong evidence supporting the long-term safety of targeting this molecule, as many individuals with severe allergies have been on anti-IgE therapy for years without negative effects. To assess if reducing IgE would diminish the body’s protective response to parasites, further tests were conducted on mice. The results indicated that the vaccine did not hinder their immune response to infections involving mouse feline, a parasitic nematode.

Koenig expresses hope regarding the vaccine’s efficacy in humans. “Research shows that the mouse-generated antibodies attach effectively to human IgE molecules. If humans can produce similar antibodies, there’s a promising chance it will be highly effective.”

Despite this optimism, Lever emphasizes that clinical trials are necessary to assess the vaccine’s safety, effectiveness, and duration in humans. If it can be commercialized, it may provide a cost-effective treatment alternative for individuals with severe allergies, requiring far fewer injections than anti-IgE monoclonal antibodies such as omalizumab.

Rising Tuberculosis Rates: Who Is Most Vulnerable?

Tuberculosis (TB) is an airborne illness that many deem to be a relic of the past. Yet, after years of decline in high-income nations like the UK and US, TB diagnoses are on the rise.

According to the UK Health and Safety Executive, tuberculosis cases in the UK are projected to increase by 13% in 2024, reaching a total of 5,480 diagnoses.

Although this number is relatively modest compared to other high-burden nations, England remains just below the World Health Organization (WHO) threshold for “low incidence” status, which is defined as 10 cases per 100,000 people.

These statistics, along with similar trends in the US, indicate that our progress has plateaued, hindering our path to TB eradication.

A Wake-Up Call

So, is tuberculosis making a resurgence? In short, it never fully disappeared.

Tuberculosis remains the deadliest infectious disease globally, claiming approximately 1.23 million lives in 2024 alone—more than HIV and malaria combined—and ranks among the top 10 causes of death worldwide.

According to WHO, over 10 million individuals contract tuberculosis each year, with a shocking quarter of these going undiagnosed and untreated. The COVID-19 pandemic has further hampered years of progress in TB control, but it’s only part of the picture.

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis, spreading through the air when an infectious person coughs, sneezes, sings, or speaks.

Common symptoms include a persistent cough lasting three weeks or more, fever, night sweats, weight loss, and fatigue. While TB commonly affects the lungs, it can impact any organ in the body.

Despite the availability of effective treatments for decades, they remain imperfect. A cure requires months of antibiotics, which can be difficult to access in certain regions. The Bacillus Calmette-Guérin (BCG) vaccine offers some protection to young children against severe forms of TB, but it does not reliably prevent the contagious lung disease prevalent in adults.

It’s crucial to note that most individuals who inhale the bacteria do not fall ill. An estimated a quarter of the global population is infected with tuberculosis, with their immune systems keeping it dormant. Latent tuberculosis can be detected through skin and blood tests, and preventive antibiotics are often prescribed to avert progression.

Individuals with weakened immune systems, including those with HIV or diabetes, those undergoing cancer treatments, and those on specific medications for conditions like rheumatoid arthritis, are at heightened risk of developing TB.

Tuberculosis primarily affects the lungs but can also impact lymph nodes, bones, brain, kidneys, and spine.

An Unbalanced Burden

Tuberculosis is closely linked to poverty and the living and working conditions of individuals. Factors like overcrowded or poorly ventilated housing, homelessness, low income, malnutrition, smoking, and alcohol dependence can elevate vulnerability to TB.

People in disadvantaged communities tend to be more frequently infected and less often diagnosed early, resulting in generally poorer health outcomes. Social stigma, healthcare system gaps, and misinterpretation of symptoms can also delay treatment.

Consequently, a human-centered model that merges medical care with psychotherapy and financial and social support is increasingly recognized as vital for effectively combating tuberculosis.

While TB impacts individuals of all genders, WHO data indicates that men aged 15 and older carry a disproportionately heavy burden, with an estimated 54% of TB cases in 2024 occurring in men, compared to 35% in women and 11% in children and adolescents.

Men also encounter greater barriers to diagnosis and treatment, with a 45% higher mortality rate after initiating treatment compared to women.

These disparities stem from various factors, including elevated rates of smoking and alcohol consumption among men, as well as occupational hazards and gender norms that deter them from seeking care.

Women and individuals of diverse sexual orientations and gender identities face their own distinct challenges. A gender-sensitive and human-centered approach is crucial for achieving the goal of tuberculosis elimination for everyone.

The WHO’s first rapid diagnostic test for tuberculosis revolutionized detection, offering results in under two hours and identifying rifampicin resistance, one of TB’s most effective treatment drugs.

A Turning Point

The good news is that scientific advancements are leading the fight against tuberculosis to new heights, with quicker diagnoses, shorter treatments, and promising vaccines.

Rapid molecular tests like Xpert MTB/RIF and Truenat can identify tuberculosis and drug resistance within hours instead of weeks. AI-assisted chest X-rays are also enhancing early detection in areas lacking radiologists.

Treatment regimens have become both shorter and safer. Current TB treatments may only take one month, while some drug-sensitive cases require four months, and drug-resistant cases can be treated in six months.

Vaccine research is progressing as well, with candidates like M72/AS01E entering late-stage clinical trials. Although these advancements signify considerable progress, ensuring equitable access for all, especially in low-resource settings, remains a significant challenge.

Research from Liverpool’s Tuberculosis Research Center highlights that stigma, discrimination, poverty, and structural barriers significantly affect the experiences of those living with TB.

Understanding the lived experiences of TB patients, as well as the obstacles and enablers in their treatment trajectories, is essential to ensure that no one is left behind.

For effective human-centered TB care, collaborations between governments, researchers, and affected communities are underway, integrating clinical care with education, mental health support, and financial assistance. Yet, there’s still much more to achieve.

The UK’s recent pledge of £850 million to the Global Fund to Fight AIDS, Tuberculosis and Malaria from 2027 to 2029 reaffirms this commitment, contributing to efforts that have reportedly saved 70 million lives since 2002.

However, it is important to note that this pledge reflects a 15% decrease from the previous financial cycle, which adds to the sobering reality of diminishing development funding impacting progress in the fight against tuberculosis.

Reductions in international aid have weakened tuberculosis programs in heavily burdened nations, with repercussions likely to extend beyond borders. Persistent political will and investment in locally relevant, people-centered strategies are crucial to achieving the goal of TB elimination for all.

So, should you be concerned about contracting tuberculosis? If you reside in the UK, generally the answer is no. TB remains rare, and infection risk for most individuals is minimal unless they have had extended, close contact with someone infected.

If your cough persists for over three weeks, particularly when accompanied by symptoms such as fever, weight loss, or night sweats, consult your physician.

RNA Molecules Discovered in 39,000-Year-Old Woolly Mammoth Tissue

Researchers have successfully extracted and sequenced ancient RNA from the tissues of 10 woolly mammoths preserved in permafrost. One of these specimens is estimated to be 39,000 years old, making it the oldest ancient RNA sequence recorded to date.

Investigating prehistoric genes and their activation is crucial for understanding the biology and evolution of extinct species.

For years, scientists have been piecing together the mammoth genome and their evolutionary history through DNA analysis.

However, RNA, which indicates active genes, has remained elusive until now.

“With RNA, we can provide direct evidence of which genes are ‘turned on’ and gain insights into the final moments of mammoths that lived during the last Ice Age,” stated Dr. Emilio Marmol, a researcher at the Globe Institute.

“This kind of information cannot be obtained from DNA alone.”

In this study, Dr. Marmol and colleagues analyzed permafrost-preserved tissue from 10 late Pleistocene woolly mammoths discovered in northeastern Siberia, spanning from the central Indigirka region to the Oyogos Yar coast and the New Siberian Islands.

“We accessed exceptionally well-preserved mammoth tissue excavated from the Siberian permafrost, expecting it to contain RNA molecules that had remained frozen over millennia,” Marmol mentioned.

“We have pushed the limits of DNA recovery for over a million years,” said Professor Rav Dalen from Stockholm University and the Center for Paleogenetics.

“Now we aimed to determine if RNA sequencing could go further back than prior research.”

Researchers successfully identified tissue-specific gene expression patterns in the muscular remains of Yuka, a 39,000-year-old juvenile mammoth.

There are over 20,000 protein-coding genes in the mammoth genome, but not all are actively expressed.

The detected RNA molecules relate to proteins crucial for muscle contraction and metabolic regulation under stress.

Researchers also discovered several RNA molecules that regulate gene activity in mammoth muscle samples.

“We found non-protein-coding RNAs, such as microRNAs, which were among our most intriguing discoveries,” Dr. Mark Friedlander from Stockholm University’s Wenner-Gren Institute remarked.

“The muscle-specific microRNAs identified in mammoth tissue provide concrete evidence of gene regulation occurring in real-time in ancient eras. This is a groundbreaking achievement.”

The identified microRNAs also enabled the authors to confirm their findings originated from mammoths.

“We found a rare mutation in a specific microRNA, providing evidence that it is of mammoth origin,” noted Dr. Bastian Flom from the Norwegian Arctic University Museum.

“We also uncovered novel genes solely based on RNA evidence, a feat not attempted before at such ancient sites.”

“RNA molecules can endure for much longer than previously assumed.”

“Our findings demonstrate that RNA can survive much longer than previously thought,” Professor Dalen added.

“This allows us to not only explore which genes are ‘turned on’ in various extinct creatures but also to sequence RNA viruses like influenza and coronaviruses that are preserved in Ice Age remains.”

These findings were published in the Journal of Cell on November 14, 2025.
