Helios 1: A Groundbreaking Quantum Computer Poised to Tackle Superconductivity Challenges

Helios-1 Quantum Computing Chip

Quantinum

At Quantinuum, researchers have harnessed the capabilities of the Helios-1 quantum computer to simulate a mathematical model traditionally used to analyze superconductivity. While classical computers can perform these simulations, this breakthrough indicates that quantum technology may soon become invaluable in the realm of materials science.

Superconductors can transmit electricity flawlessly, yet they only operate at exceedingly low temperatures, rendering them impractical. For decades, physicists have sought to modify the structural characteristics of superconductors to enable functionality at room temperature, and many believe the solution lies within a mathematical framework known as the Fermi-Hubbard model. This model is regarded by Quantinuum researchers as a significant component of condensed matter physics. For additional insights, see Henrik Dreyer.

While traditional computers excel at simulating the Fermi-Hubbard model, they struggle with large samples and fluctuating material properties. In comparison, quantum computers like Helios-1 are poised to excel in these areas. Dreyer and colleagues achieved a milestone by conducting the most extensive simulation of the Fermi-Hubbard model on a quantum platform.

The team employed the Helios-1, which operates with 98 qubits derived from barium ions. These qubits are manipulated using lasers and electromagnetic fields to execute the simulations. By adjusting the qubits through various quantum states, they collected data on their properties. Their simulation encompassed 36 fermions, the exact particles typical in superconductors, represented mathematically by the Fermi-Hubbard model.

Past experiments show that fermions must form pairs for superconductors to function, an effect that can be induced by laser light. The Quantinuum team modeled this scenario, applying laser pulses to the qubits and measuring the resulting states to detect signs of particle pairing. Although the simulation didn’t replicate the experiment precisely, it captured key dynamic processes that are often challenging to model using traditional computational methods with larger particle numbers.

Dreyer mentioned that while the experiment does not definitively establish an advantage for Helios-1 over classical computing, it gives the team assurance in the competitiveness of quantum computers compared to traditional simulation techniques. “Utilizing our methods, we found it practically impossible to reproduce the results consistently on classical systems, whereas it only takes hours with a quantum computer,” he stated. Essentially, the time estimates for classical calculations were so extended that determining equivalence with Helios’ performance became challenging.

The Trapped Ions Function as Qubits in the Helios-1 Chip

No other quantum computer has yet endeavored to simulate fermion pairs for superconductivity, with the researchers attributing their achievement to Helios’ advanced hardware. David Hayes from Quantinuum remarked on Helios’ qubits being exceptionally reliable and their proficiency in industry-standard benchmarking tasks. Preliminary experiments yielded maintenance of error-free qubits, including a feat of entangling 94 specialized qubits—setting a new record across all quantum platforms. The utilization of such qubits in subsequent simulations could enhance their precision.

Eduardo Ibarra Garcia Padilla, a researcher at California’s Harvey Mudd University, indicated that the new findings hold promise but require careful benchmarks against leading classical computer simulations. The Fermi-Hubbard model has intrigued physicists since the 1960s, so he’s eager for advanced tools to further its study.

Uncertainty surrounds the timeline for approaches like Helios-1 to rival the leading conventional computers, according to Steve White from the University of California, Irvine. He noted that many essential details remain unresolved, particularly ensuring that quantum simulations commence with the appropriate qubit properties. Nevertheless, White posits that quantum simulations could complement classical methods, particularly in exploring the dynamic behaviors of materials.

“They are progressing toward being valuable simulation tools for condensed matter physics,” he stated, but added, “It remains early days, and computational challenges persist.”

Amazon Files Lawsuit Against AI Startup Over Automated Shopping Features in Browser

On Tuesday, Amazon filed a lawsuit against a well-known artificial intelligence startup over a feature in its browser that enables users to automate purchases. Amazon alleged that Perplexity AI had illicitly accessed customer accounts and disguised the AI’s actions as human browsing.

“The misconduct by Perplexity must cease,” Amazon’s legal representatives stated. “Perplexity has no permission to act where it is forbidden. The intrusion involves a code rather than a lockpick, rendering it equally illegal.”

Perplexity, which has experienced significant growth in light of the AI assistant boom, previously accused Amazon of leveraging its dominant market position to suppress competition and dismissed Amazon’s allegations.


“Bullying occurs when larger companies employ legal threats and intimidation to stifle innovation and negatively impact people’s lives,” the company expressed in a blog post.

This dispute underscores new conversations regarding the regulation of the increasing use of AI agents, AI-powered autonomous digital assistants, and their interactions with websites.

In its legal action, Amazon accused Perplexity of secretly accessing Amazon’s private customer accounts via the Comet browser and associated AI agents, misrepresenting automated actions as human browsing. Amazon asserted that Perplexity’s systems endangered customer data and ignored repeated calls to shut them down.

“Instead of being transparent, Perplexity deliberately configures its CometAI software to mask Comet AI agent activity on Amazon’s platforms,” the company stated.

Amazon’s complaint also claimed that Perplexity’s Comet AI agent undermined the shopping experience for customers and hindered Amazon’s ability to guarantee that users benefiting from the agent receive the personalized shopping experience it has developed over decades.

In a previous statement, Amazon indicated that third-party applications making purchases on behalf of users should operate transparently and respect companies’ preferences for participation.

Perplexity had earlier revealed that it received legal threats from Amazon aimed at preventing Comet AI agents from shopping on its platform, asserting that this action poses a wider threat to user choice and the future of AI assistants.

Perplexity is among several AI startups that are restructuring web browsers to incorporate artificial intelligence, aiming to enhance user autonomy and simplify everyday online tasks, from composing emails to completing purchases.

Amazon is also developing similar functionalities, including Buy For Me, which enables users to shop across various brands within the app, and Rufus, an AI assistant that recommends products and manages shopping carts.

The Comet browser’s AI agent from Perplexity acts as a purchasing and comparison assistant for users. The company contends that user credentials are stored locally and not on its servers, asserting that users have the right to select their own AI assistant and framing Amazon’s actions as an attempt to safeguard its business model.

“Simplified shopping leads to more transactions and greater customer satisfaction,” Perplexity remarked. “However, Amazon is less focused on that and more on serving ads.”

‘Fortnite’ Creator and Google Resolve Five-Year Legal Dispute Over Android App Store

Epic Games, the creator of Fortnite, has come to a “comprehensive settlement” with Google, which may mark the end of a legal dispute lasting five years regarding Google’s Play Store for Android applications, as stated in joint legal filings by both parties.

Tim Sweeney, CEO of Epic, hailed the settlement as a “fantastic offer” in a post on social media.

In documents submitted on Tuesday to the federal court in San Francisco, both Google and Epic Games noted that the settlement “enables the parties to set aside their differences while fostering a more dynamic and competitive Android environment for users and developers.”

Skip past newsletter promotions

Epic secured a significant legal victory over Google earlier this summer when a federal appeals court upheld a jury’s verdict declaring the Android app store an illegal monopoly. The unanimous decision opens the door for federal judges to potentially mandate substantial restructuring to enhance consumer choices.

While the specific settlement terms remain confidential and require approval from U.S. District Judge James Donato, both companies provided an overview of the agreement in their joint filing. A public hearing is set for Thursday.

The settlement appears to align closely with the October 2024 ruling by Donato, which directed Google to dismantle barriers that protect the Android app store from competition. It also includes a provision requiring the company’s app stores to support the distribution of competing third-party app stores, allowing users to download apps freely.


Google had aimed to reverse these decisions through appeal, but the ruling from the 9th Circuit Court of Appeals in July posed a significant challenge to the tech giant, which is now facing three separate antitrust cases that could impact various aspects of its internet operations.

In 2020, Epic Games launched a lawsuit against both Google’s Play Store and Apple’s iPhone App Store, seeking to bypass proprietary payment processing systems that impose fees ranging from 15% to 30% on in-app transactions. The proposed settlement put forth on Tuesday aims to decrease those fees to a range between 9% and 20%, depending on the specific agreement.

Study Suggests Men Should Exercise Twice as Long as Women for Heart Health

Research indicates that men may need to engage in exercise for twice as long as women to obtain equivalent health benefits, according to a significant new study involving 85,000 participants.

Findings revealed that women performing approximately four hours of moderate to vigorous exercise weekly, such as brisk jogging, swimming, or dancing, could lower their risk of coronary heart disease by 30 percent. In contrast, men required nearly nine hours of physical activity per week to achieve the same risk reduction.

“In comparison to men, women allocate half the time to exercise for similar health outcomes,” the researchers noted in their publication. Nature cardiovascular research.






While the research team did not explore the reasons for this notable difference, they proposed several physiological explanations.

Women possess higher estrogen levels, a hormone linked to bone and muscle health along with fat metabolism rates.

Additionally, men and women have different types of skeletal muscles, which may make women more adept at endurance training.

“Heart disease is the primary cause of premature death in both genders, though men typically develop heart disease earlier, and women tend to ‘catch up’ later in life after menopause,” stated Professor Riyaz Patel, a cardiologist at University College London, who was not part of the study. BBC Science Focus.

“The takeaway is that everyone can benefit from exercise. Increased physical activity is advantageous for all.”

The study, led by Jiajin Chen from Xiamen University in China, monitored participants aged 37 to 73 using wrist-worn fitness trackers over an eight-year period.

For individuals with pre-existing cardiovascular conditions, women required just 51 minutes of exercise weekly to reduce their risk of death by 30 percent, compared to 85 minutes for men.

Heart disease remains the leading cause of early death globally. In the United States alone, about 100 out of every 100,000 women are anticipated to die from cardiovascular disease in 2023, while the figure for men is 60% higher.

The World Health Organization, along with the American Heart Association and NHS, advises individuals aged 16 to 64, regardless of gender, to engage in 150 minutes of moderate to vigorous physical activity per week.

Toxic Algae in South Australia: A Potential Global Threat

Algal Bloom Devastates Fish Populations in South Australia

Australian Associated Press/Alamy

A vast and lethal algal bloom has wreaked havoc in South Australia over the past eight months, impacting over 20,000 square kilometers of marine habitat. An estimated 1 million animals from more than 550 species have perished, significantly affecting human health as well.

Researchers have recently pinpointed the species responsible for this ecological calamity, cautioning that it represents a “new international threat with unpredictable outcomes.”

The alarming agent is a type of algae known as Karenia cristata. Previously, it was documented only in two locales near South Africa, where it resulted in fish die-offs in 1989 and the mid-1990s, as well as off the coast of Newfoundland, Canada.

The research team has also identified a novel toxin released by K. cristata, which belongs to a group of compounds called brevetoxins. These toxins can inflict neurological harm on marine creatures, damage fish gills, and lead to fatalities in various species, including sea dragons, great white sharks, and dolphins. Brevetoxins pose a risk to humans via inhalation or ingestion.

Team member Shona Murray, a professor at the University of Technology Sydney, expressed concern among international colleagues regarding the implications of a new toxin-producing species potentially appearing in their waters.

“We are aware that this algal bloom has the capacity to proliferate in other parts of the world,” she cautions. “Previously, we underestimated its ability to create extensive and destructive blooms that could persist for eight months.

“Now we have confirmation, and it’s evident that it’s already occurring in other global regions; thus, I consider it an international threat.”

Murray and her research team noted that nearly 850 instances of harmful marine algal blooms have been documented worldwide from 1985 to 2025, with the recent South Australian event considered “one of the most severe and widespread” ever recorded globally.

The researchers have yet to determine the reason for such a vast and lethal bloom. The rising frequency of harmful blooms globally has been linked to increasing ocean temperatures, and the outbreak coincided with a significant marine heatwave, where water temperatures soared up to 3 degrees Celsius above normal. Nevertheless, the unexpected expansion of the blooms occurred after May 2025 when ocean temperatures began to decline.

K. cristata researchers emphasize the urgent need to comprehend the triggers for the bloom, noting that, given the right circumstances, it could impact numerous countries.

Christopher Keneally from the University of Adelaide points out that the dominant Karenia species previously identified, Karenia mikimotoi, is not known for producing brevetoxins. “There are numerous uncertainties regarding how the specific toxins produced by this species influence humans,” he states.

He concurs that the discovery raises concerns about potential new threats arising beyond Australia. “Given this species’ wide global distribution, it’s likely already present in small quantities in various coastal areas worldwide,” he adds. “As nutrient levels rise in many urbanized coastal regions and sea surface temperatures escalate, we can rightly predict that a variety of bloom-forming organisms will become increasingly prevalent.”

Examining Gender Bias in Facebook’s Job Ads: Insights from France’s Equality Monitoring Regulations

France’s equality regulator has determined that Facebook’s job advertising algorithm is discriminatory towards women, following an investigation that revealed a bias in job ads for mechanics favoring men, while ads for kindergarten teaching positions were predominantly shown to women.

The watchdog group, Défenseur des Droits, contended that Facebook’s targeted job ad system discriminates based on gender, which constitutes indirect discrimination. The regulator advised Facebook and its parent company, Meta, to implement measures to eliminate discriminatory practices in advertising and granted the company three months to inform French authorities of its actions.

According to the regulator’s ruling, “The system implemented for distributing job listings treats Facebook users differently based on their gender, thereby resulting in indirect gender discrimination.”

This ruling followed an initiative from Global Witness, a campaign organization focused on examining the influence of major tech firms on human rights, which posted advertisements on Facebook that included links to various job opportunities across countries like France, the UK, Ireland, and South Africa.

The findings revealed that, notably in France, 90% of individuals seeing ads for mechanic positions were men, whereas the same percentage of those encountering kindergarten teacher ads were women. Additionally, 80% of viewers for psychologist job ads were women, while 70% of those seeing pilot job ads were men.

Global Witness, along with French women’s rights organizations La Fondation des Femmes and Femme Ingénue, which had reached out to the rights group, praised the ruling.

In a joint statement, they remarked, “This seems to be the first instance where a European regulator has ruled that a social media platform’s algorithms exhibit gender discrimination, marking significant progress in holding these platforms accountable under existing legislation.”

“This decision conveys a powerful message to all digital platforms that they will be held responsible for such biases,” stated attorney Josephine Sheffet, representing the plaintiffs. “This legal principle establishes a crucial precedent for future legal actions.”

Mr. Mehta disputed the ruling, with a spokesperson stating: “We disagree with this decision and are exploring our options.”

Meta had agreed to modify Facebook’s algorithms in 2022 after allegations from the U.S. Department of Justice suggested that the platform’s housing advertising system discriminated against users based on criteria like race, religion, and gender.

COP30: Key Agenda Items for the Belem Climate Summit

Solar power plants in South Africa – discussions on clean energy support at COP30

This year’s COP, commencing on November 10 in Belém, Brazil, is not expected to yield a substantial new global agreement for addressing climate change. The emphasis will be on clarifying the operational details of existing agreements.

Prior to the summit, nations were tasked with submitting revised pledges to lower emissions, called Nationally Determined Contributions (NDCs). However, only 67 out of 195 signatories of the Paris Agreement have done so. Countries have until the end of October to revise their plans; ones to watch are the European Union, which has set targets as a consortium, and India, which is currently lagging. Additionally, President Donald Trump’s exit from the Paris Agreement effectively rendered the United States’ commitments void. Goals submitted under President Joe Biden’s administration are expected in December 2024.

On a more optimistic note, China has committed to reducing net greenhouse gas emissions by 7 to 10 percent from their peak by 2035. While this falls short of curbing global warming to 2°C, it marks a progress towards the country’s initial absolute emissions reduction target. “This is a significant advance compared to what we’ve witnessed in the past, and it’s essential to view it positively,” remarked Manuel Pulgar Vidal, WWF’s global leader for climate and energy.

Adapting to climate change

Two agenda items may play critical roles in both mitigating and adapting to climate change.

Brazil is championing the Belém Action Mechanism for a Just Transition, a fresh approach that repositions the global shift to clean energy as an avenue for job creation and growth rather than just economic hardship. The initiative aims to aid nations in transforming key sectors such as energy, mining, and agriculture, anticipating pledges and systems to revamp industries while supporting communities impacted by these transitions.

However, in light of the severe backdrop of climate change, COP’s agenda seems to be transitioning from preventing climate change to adapting to its impacts. “COPs 1 through 29 unfolded under one climate paradigm; we now face a different climate reality, necessitating efforts to enhance safety for people,” noted Laurie Rayborn, a member of the climate think tank “Strategic Climate Risk Initiative.”

Another significant initiative is the Global Goals on Adaptation (GGA), which aims to quantify and compare the vulnerability of nations to climate change. It is set to include approximately 100 indicators like flood risk and food security. The GGA will facilitate global decisions on which nations should receive financial support and is a critical step toward financing those most affected.

However, world leaders must avoid becoming overly fixated on adaptation at the expense of mitigation, cautioned Leyborn. “There are scenarios where mitigation takes a backseat, but that leads to nowhere. Less mitigation translates to more adaptation, and we could be caught in a destructive cycle.”

Addressing fiscal disparities

As affluent nations fall short in providing the necessary financing for developing countries to adapt and combat climate change, Brazil aims to maintain funding aligned with the Baku to Belém roadmap. The target is to escalate global climate finance to $1.3 trillion annually by 2035.

Low-income nations are looking to their wealthier counterparts for subsidies while they struggle with the impacts of significant emissions that harm their agriculture. Wealthy nations are exploring funding avenues via private investments, debt exchanges, development bank support, and innovative financing strategies such as Tropical Forest Forever Facilities (TFFFs).

The TFFF is anticipated to launch formally at COP30 to finance forest conservation through private investment. Brazil and other nations will secure initial investments into the fund, which can then borrow nearly $100 billion from major private investors at favorable interest rates. The TFFF will reinvest these borrowed funds into sustainable initiatives that yield higher returns, with profits directly benefiting nations that safeguard their forests.

Brazil is already committing a billion dollars while the World Bank has agreed to host the fund by the end of October. The TFFF has the potential to create a sustainable conservation model that could generate $4 billion each year for the preservation of the world’s diminishing forests.

With few ambitious declarations anticipated at the COP, the pressure on the TFFF to succeed is rising, necessitating substantial investments from many nations in the billions.

“The TFFF’s launch is likely to be a highlight amid the struggles faced in international climate negotiations. Its success will serve as a crucial indicator for the future we face with significant climate shifts,” stated Simon Zadek from Morphosys, a Swiss climate finance consulting firm.

Ancient DNA May Transform Our Understanding of Iceland’s Early Settlers

While historical accounts claim that Ingólfr Arnarson was the first Norse settler to reach Iceland in the 870s, this assertion might not hold true.

Public domain

Norsemen may have arrived in Iceland as much as 70 years earlier than previously believed, and their arrival might not have been the environmental catastrophe often depicted.

Traditionally, it’s stated that Iceland saw its first settlement in the 870s. This early migration is frequently viewed as an ecological calamity brought on by Viking raiders and Norse settlers who cleared the forests for fuel, construction materials, and arable land. Today, less than 2 percent of the country is still forested.

Finding concrete evidence regarding the arrival of these early settlers has been challenging. Archaeologists have discovered an ancient wooden longhouse, estimated to be from around 874 AD, located near Stódvarfjordur in eastern Iceland. This old longhouse is thought to have been a summer dwelling established in the 800s, though this finding has yet to be documented in scientific journals.

Currently, Eske Willerslev, a professor at the University of Copenhagen, and his team examined environmental DNA (eDNA) gathered from sediment cores drilled in Lake Tjörnin, an area in central Reykjavík, one of Iceland’s earliest and continuously inhabited locations, to identify which species existed and their timestamps. They analyzed volcanic ash layers, alongside radiocarbon dating and plutonium isotope assessments, to develop a timeline from about 200 AD up to contemporary times, integrating known historical events.

A significant marker in their research is the Randonham tephra layer, formed from volcanic ash deposited during eruptions around 877 AD. The bulk of evidence indicating human habitation in Iceland is found above this layer, indicating subsequent settlement.

“The signs beneath the tephra provide compelling evidence for earlier human activity,” Comments Chris Callow from the University of Birmingham, UK, who did not participate in the research.

Willerslev and his colleagues postulate that humans may have arrived as early as 810 AD. This inference is based on an observed rise in levoglucosan, a compound linked to biomass burning, and a subsequent increase in sewage-related viruses.

“If it were 850, I wouldn’t have been so surprised, but 810 represents rapid Viking expansion in the North Atlantic,” Callow remarks. “Overall, this aligns with our suspicions, but a date as early as 810 remains contentious.”

While piecing together a thorough environmental history of the region is noteworthy, the evidence supporting such an early arrival remains questionable. Kathryn Catlin from Jacksonville State University in Alabama stated, “The sewage biomarkers only show a slight increase around 800, nothing until 1900. Where are the indicators of sewage and human activity in between?” She also pointed out that while biomass burning could imply human presence, natural occurrences like lightning could also ignite fires.

Willerslev and his colleagues opted not to conduct interviews. New Scientist also noted that the settlers’ arrival corresponded with an uptick in local biodiversity. Genetic data imply they brought grazing animals, cultivated hay, and grew barley on a small scale for brewing purposes.

In contrast to the widespread narrative of swift deforestation, eDNA from pollen samples revealed that birch and willow trees expanded during the settlement era. Notably, birch pollen grains rose fivefold between 900 and 1200 AD, a shift researchers believe may have been influenced by settlers managing the area to protect timber and fuel sources.

“This significantly contradicts earlier claims that Vikings arrived in Iceland and immediately caused environmental destruction,” Katrin stated.

Although sheep, cattle, pigs, and horses do not appear in considerable numbers until decades after the initial settlement, Willerslev and his colleagues propose this lag may stem from the 20-year period required to build up detectable herds in eDNA records.

Callow posits another explanation: the first inhabitants may have only visited during the summer months for walrus ivory, possibly arriving without many animals. “They could have intended to hunt a few walruses and return home,” he suggested.

eDNA indicators imply the significant loss of biodiversity, including birch and willow trees, didn’t transpire until after 1200. Willerslev and his team associate this decline with the cooler climate associated with the Little Ice Age, rather than direct effects from settlers. This marked a period of colder temperatures from approximately 1250 to around 1860, compounded by volcanic eruptions and storm surges.

Global Stock Markets Dive Amid AI Bubble Fears

Global stock markets have seen a sharp decline as fears grow that the surge in valuations for artificial intelligence (AI) companies is losing steam.

U.S., Asian, and European markets all dropped following warnings from bank executives about a possible significant market correction, spurred by record highs that made several firms seem overvalued.

On Tuesday, the tech-centric Nasdaq and S&P 500 experienced their largest single-day drops in almost a month.

Tech stocks heavily influenced the Nasdaq’s decline, which closed down by 2%. The AI stocks of the “grand seven” companies—including Nvidia, Amazon, Apple, Microsoft, Tesla, Alphabet (the parent company of Google), and Meta (the owner of Facebook, Instagram, and WhatsApp)—all recorded losses.

The S&P 500 faced setbacks primarily from tech stocks, notably Palantir, which saw an almost 8% decrease despite raising its earnings expectations just a day prior, ultimately finishing the session down by more than 1%.

Palantir has also found itself in the crosshairs of prominent short sellers who wager on a decline in its stock value.

Michael Burry, the investor renowned for predicting the 2008 financial crisis and inspiring the film The Big Short, has taken positions on two major AI firms, Palantir and Nvidia, drawing backlash from Palantir’s management and contributing to a drop in its stock price.

In a CNBC interview, Alex Karp, the CEO of Palantir, criticized Burry and other short sellers for attempting to “cast doubt on the AI revolution.”

Asian markets mirrored the decline experienced in the United States, suffering their largest drop in seven months amid concerns regarding tech stock performance, with Japanese and South Korean indexes falling over 5% from record highs reached just a day before. European markets in the U.K., France, and Germany also saw slight declines on Wednesday morning.

The market downturn follows cautionary statements from the CEOs of Morgan Stanley and Goldman Sachs about a potential correction.

Their warnings echo concerns raised by Jamie Dimon, CEO of JPMorgan Chase, the largest U.S. bank, who predicted in October that the market might crash within the next six months to two years.

“The chorus is getting louder,” stated Jim Reid, an analyst at Deutsche Bank. “We’re having discussions about whether we are on the verge of a stock price correction.”

“The last 24 hours have revealed a clear risk-off trend, as apprehensions regarding high valuations of tech companies have negatively impacted investor confidence,” Reid remarked.

Other analysts have raised doubts about investing in AI companies, noting that while substantial funding has been directed to a handful of tech firms, like OpenAI and Nvidia, the returns on investment thus far remain minimal.

Bitcoin prices briefly dipped below $100,000 (£76,764) for the first time since June, as investors divested from high-risk assets like cryptocurrencies due to economic uncertainty.

While Bitcoin hit a peak of over $126,000 in early October, it fell 3.7% throughout the month, marking its worst monthly performance in a decade, according to CoinMarketCap statistics.

We Definitely Need a Sequel to PowerWash Simulator Right Now

Does the world truly require another PowerWash Simulator game? Many would argue against it, likely those who haven’t experienced the original and fail to grasp its charm, but who prefer to tilt their heads in confusion and disapproval and ask: “What do you do in the game? Just wash things?”

(It’s rather unfair that other hobbies don’t face this scrutiny. No one questions, “Wait, you’re just running in circles at a 5k?” or “So, you’re just playing with a ball?”)

The quick answer is yes. Simply direct the hose at the grime around you, be it a bungalow, a monster truck, or Lara Croft’s mansion, and obliterate it. After finishing each section, a calming “ding” sounds, and your brain gets a dopamine boost. This is the sole sound in the game apart from the rush of water and the sporadic clatter of metal ladders. The entire experience is wonderfully pleasant, deeply fulfilling, and captivating. I absolutely love it.

I was so enamored that in 2023, I streamed PowerWash Simulator on Twitch for 24 hours, 6 minutes, and 33 seconds – setting a Guinness World Record for the longest gaming marathon.

Wash this…PowerWash Simulator 2. Photo: FuturLab

Not recommended. While the game is enjoyable, the novelty tends to wear off after around 20 hours. I recall things getting strange around 4 AM. The vibrant colors of the children’s play area I was cleaning began swirling in a psychedelic whirlwind. My vision blurred, my fingers ached, and I felt a surge of frustration towards the local council for the state of the climbing frame.

I persevered, buoyed by the Twitch community’s support. They reminded me of the reality outside the game. Yet, I had lingering flashbacks for months. Occasionally, as I lay in bed at night, I’d think I could still hear the constant hissing of the jets, worried I might have a ringing in my ears. I still struggle to walk past a slide without checking for mold underneath.

Interestingly, after my record-setting marathon, I didn’t feel inclined to return to PowerWash Simulator for a while. However, diving into the sequel brought back that thrill of achievement that comes from erasing the final speck of grime from a chrome toilet bowl. Pure bliss.

This article helps you to be more forgiving about cleaning every nook and cranny. There’s also a new target icon that indicates missed spots, making mission completion less frustrating.

And of course, there are fresh objects to clean. PowerWash Simulator 2 offers a total of 38 missions, featuring airships, mobility scooters, shopping malls, and more. New tools include a surface cleaner for efficient floor scrubbing and a harness system for rappelling down buildings. Additionally, there’s a new home base to showcase your achievements. This is particularly appealing if you’re the type to display (three) Guinness World Record certificates prominently for delivery drivers to see upon entry.

While none of these enhancements create a substantial shift from the original game, it’s also unlikely that a sequel will attract those who didn’t understand the initial charm. Nevertheless, PowerWash Simulator 2 delivers what fans desire: fresh cleaning challenges, new toys to experiment with, and even less difficult but gratifying gameplay. Plus, there’s the option to occasionally draw crude representations of male genitalia in the grime for comedic effect. In a world filled with chaos, this is exactly the game we need right now.

AI Research Sheds Light on Why Super-Recognition Skills Excel in Face Identification

They are salisbury novichok addict uncovering a murder suspect or even identifying a sexual predator. The research offers fresh insights into why superrecognizers excel at facial recognition.

Previous studies indicate that individuals with exceptional facial recognition skills observe more regions of the entire face compared to average individuals.

Recently, researchers have employed advanced AI techniques to reveal how this perspective enhances their capabilities.

“It’s not solely about seeing everything, it’s about using your vision intelligently,” stated the lead author of the study, Dr. James Dunn from UNSW Sydney.


In a recent article published in Proceedings of the Royal Society B: Biological Sciences, Dunn et al. highlight how they extracted eye-tracking data from a previous study involving 37 superrecognizers and 68 typical recognizers.

In their experiment, participants viewed both images of entire faces and segmented images focusing on the regions they were examining.

In this new research, the team utilized this data to reconstruct the visual information that was available to the participants’ eyes.

This “retinal information” was processed through a deep neural network (DNN), an AI system trained for facial recognition. Participants provided the AI with either a complete image of the same face they had seen or a different one.

In all instances, the AI generated a score indicating how closely the retinal information matched a given complete facial image.

The research team compared outcomes between typical participants and super-recognizers, along with data drawn from randomly chosen areas of the initial facial images.

The findings indicated that the AI system’s effectiveness improved as the visibility of the observed facial feature increased.

Moreover, across all levels of visibility, the AI performed optimally when relying on retinal data from superrecognizers.

“This suggests that variations in facial recognition capability are partly due to our active exploration and sampling of visual data, rather than just post-processing by the brain,” Dunn remarked.

The team then examined whether their findings simply indicated that superrecognizers looked at more areas of the face and gathered more data.

However, they discovered that even when the same amount of retinal information was captured, the AI performed better with data from super-recognizers.

“Their advantage lies not only in the quantity but also in the quality of information,” says Dunn. “They focus on areas that provide more identity cues, making each ‘pixel’ they select significantly more valuable for facial recognition.”

Dr. Rachel Bennett, a facial processing expert from Brunel University in London who was not involved in the study, praised the research.

“The key contribution to understanding super-recognition is that effective facial recognition isn’t only about examining specific areas or spending more time looking at the face. Super-recognizers explore not just larger areas, but also gather more advantageous data,” she asserted.

Dr. Alejandro Estudillo from Bournemouth University noted that the study was conducted by showing participants still images in highly controlled environments.

“It will be crucial to see if the same patterns emerge in more natural, dynamic contexts,” he said.

This study implies there are strategies to enhance facial recognition; however, it seems unlikely that anyone can train to become a super-recognizer.

“At present, we cannot determine if these eye movement patterns can be effectively trained,” Bennett remarked.

Dunn stated that research indicates super-recognition is likely influenced by genetics and is often inherited.

“Superrecognizers appear to instinctively identify the most crucial features. This is challenging to teach, as it differs from one face to another,” he explained.

Researchers have created a free test to help identify supercognitive traits: New South Wales face test.

Chilling Effect: How Fear of ‘Naked’ Apps and AI Deepfakes is Driving Indian Women Away from the Internet

Gaatha Sarvaiya enjoys sharing her artistic endeavors on social media. As a law graduate from India in her early 20s, she is at the outset of her professional journey, striving to attract public interest. However, the emergence of AI-driven deepfakes poses a significant threat, making it uncertain whether the images she shares will be transformed into something inappropriate or unsettling.

“I immediately considered, ‘Okay, maybe this isn’t safe. People could take our pictures and manipulate them,'” Sarvaiya, who resides in Mumbai, expresses.

“There is certainly a chilling effect,” notes Rohini Lakshane, a gender rights and digital policy researcher based in Mysore. He too refrains from posting photos of himself online. “Given how easily it can be exploited, I remain particularly cautious.”

In recent years, India has emerged as a crucial testing ground for AI technologies, becoming the second-largest market for OpenAI with the technology being widely embraced across various professions.

However, a report released recently reveals that the growing usage of AI is generating formidable new avenues for harassment directed at women, according to data compiled by the Rati Foundation, which operates a national helpline for online abuse victims.

“Over the past three years, we’ve identified that a significant majority of AI-generated content is utilized to target women and sexual minorities,” the report, prepared by Tuttle, a company focused on curbing misinformation on social media in India, asserts.

The report highlights the increasing use of AI tools for digitally altering images and videos of women, including nudes and culturally sensitive content. While these images may be accepted in Western cultures, they are often rebuked in numerous Indian communities for their portrayal of public affection.

The findings indicated that approximately 10% of the numerous cases documented by the helpline involve such altered images. “AI significantly simplifies the creation of realistic-looking content,” the report notes.

There was a notable case where an Indian woman’s likeness was manipulated by an AI tool in a public location. Bollywood singer Asha Bhosle‘s image and voice were replicated using AI and distributed on YouTube. Journalist Rana Ayyub faced a campaign targeting her personal information last year, with deepfake sexual images appearing of her on social media.

These instances sparked widespread societal discussions, with some public figures like Bhosle asserting that they have successfully claimed legal rights concerning their voice and image. However, the broader implications for everyday women like Sarvaiya, who increasingly fear engaging online, are less frequently discussed.

“When individuals encounter online harassment, they often self-censor or become less active online as a direct consequence,” explains Tarunima Prabhakar, co-founder of Tattle. Her organization conducted focus group research for two years across India to gauge the societal impacts of digital abuse.

“The predominant emotion we identified is one of fatigue,” she remarks. “This fatigue often leads them to withdraw entirely from online platforms.”

In recent years, Sarvaiya and her peers have monitored high-profile deepfake abuse cases, including those of Ayyub and Bollywood actress Rashmika Mandanna. “It’s a bit frightening for women here,” she admits.

Currently, Sarvaiya is reluctant to share anything on social media and has opted to keep her Instagram account private. She fears this measure may not suffice to safeguard her. Women are sometimes captured in public places, such as subways, with their photos potentially surfacing online later.

“It’s not as prevalent as some might believe, but luck can be unpredictable,” she observes. “A friend of a friend is actually facing threats online.”

Lakshane mentions that she often requests not to be photographed at events where she speaks. Despite her precautions, she is mentally preparing for the possibility that a deepfake image or video of her could emerge. In the app, her profile image is an illustration of herself, rather than a photo.

“Women with a public platform, an online presence, and those who express political opinions face a significant risk of image misuse,” she highlights.

Rati’s report details how AI applications, such as “nudification” and nudity apps designed to remove clothing from images, have normalized behaviors that were once seen as extreme. In one reported case, a woman approached the helpline after her photo, originally submitted for a loan application, was misused for extortion.

“When she declined to continue payments, her uploaded photo was digitally altered with the nudify app and superimposed onto a pornographic image,” the report details.

This altered image, accompanied by her phone number, was circulated on WhatsApp, resulting in a flood of sexually explicit calls and messages from strangers. The woman expressed to the helpline that she felt “humiliated and socially stigmatized, as though I had ‘become involved in something sordid’.”

In India, similar to many regions globally, deepfakes exist within a legal gray area. Although certain statutes may prohibit them, Rati’s report highlights existing laws in India that could apply to online harassment and intimidation, enabling women to report AI deepfakes as well.

“However, the process is often lengthy,” Sarvaiya shares, emphasizing that India’s legal framework is not adequately prepared to address issues surrounding AI deepfakes. “There is a significant amount of bureaucracy involved in seeking justice for what has occurred.”

A significant part of the problem lies with the platforms through which such images are disseminated, including YouTube, Meta, X, Instagram, and WhatsApp. Indian law enforcement agencies describe the process of compelling these companies to eliminate abusive content as “often opaque, resource-draining, inconsistent, and ineffective,” according to a report published by Equality Now, an organization advocating for women’s rights.

Meanwhile, Apple and Meta have recently responded accordingly. Rati’s report uncovers multiple instances where these platforms inadequately addressed online abuse, thereby exacerbating the spread of the nudify app.

Although WhatsApp did respond in the extortion scenario, the action was deemed “insufficient” since the altered images had already proliferated across the internet, Rati indicated. In another instance, an Instagram creator in India was targeted by a troll who shared nude clips, yet Instagram only reacted after “persistent efforts” and with a “delayed and inadequate” response.


The report indicates that victims reporting harassment on these platforms often go unheard, prompting them to reach out to helplines. Furthermore, even when accounts disseminating abusive material are removed, such content tends to resurface, a phenomenon Rati describes as “content recidivism.”

“One persistent characteristic of AI abuse is its tendency to proliferate: it is easily produced, broadly shared, and repeated multiple times,” Rati states. Confronting this issue “will necessitate much greater transparency and data accessibility from the platforms themselves.”

Elon Musk, AI, and ‘Radical Left Activism’: Insights from Wikipedia’s Creator on Its Greatest Threat

Few websites are as essential to the internet as Wikipedia.

This digital encyclopedia was established by Jimmy Wales roughly 25 years ago while he was involved with the expert-driven initiative “Nupedia.”

Although Nupedia didn’t gain traction, its successor evolved into one of the most significant platforms online. Currently, there are over 7 million articles available in English alone.

So, where does Wikipedia stand as distinguishing fact from fiction becomes increasingly challenging and artificial intelligence (AI) transforms how we generate and access knowledge?

To explore this, BBC Science Focus held a discussion with Wales. He shared insights on the evolution of platforms over the last two decades, the challenge of sustaining trust and neutrality amidst misinformation, and how AI might shape the future.







SF: You’ve mentioned that social media contributes to a decline in trust. Can Wikipedia still thrive in such an environment?

JW: I believe we can certainly hold our own. I don’t necessarily view it as a competition, akin to business rivalries or transportation competition.

There’s a growing sentiment advocating for a shift from cultural conflicts to more thoughtful and respectful interactions, embracing differences, and promoting dialogue across divides.

Yet, division is an inherent aspect of human nature. For instance, when people discuss today’s youth, they often claim they lack attention spans and are perpetually glued to their phones. However, it’s evident that while they enjoy captivating short-form content, they can also binge-watch intricate TV series for extended hours.

Both represent facets of the human experience and can exist simultaneously—light-hearted social media and serious inquiry. Much like our dietary habits, we should ensure a balance, avoiding just junk food while incorporating nutritious options.

SF: How has Wikipedia managed to foster a relatively constructive culture while the rest of the internet seems to decline?

JW: I appreciate your use of “relatively constructive,” which recognizes that we face internal disputes and occasional anger—it’s part of being human.

It’s fundamentally about design—both in terms of software and what I term community design. It’s a blend of various factors.

When a business model relies heavily on ad revenue and user engagement, it becomes tempting to promote content that elicits longer viewing times, anger, or arguments, rather than happiness. This approach can be unhealthy in the long term.

Conversely, Wikipedia operates without ads and is funded by public donations. Thus, our model positions us as a charity, which means we aim to minimize clicks and keep users engaged without overwhelming them.

This necessitates a divergent approach to site design and community guidelines.

Civilized discussion is crucial. Without it, Wikipedia could become rampant with misinformation. I believe numerous foundational elements contribute to our success.

SF: Recently, Wikipedia has encountered increased criticism—Elon Musk even referred to it as “Walkpedia.” How do you feel about that?

JW: That’s unfortunate. When Elon labels us “Walkpedia,” he’s mistaken and misinformed. That assertion is baseless.

For instance, regarding transgender topics, there’s a common “gotcha” question: “What is a woman?” Wikipedia’s entry for “female” defines it as “an adult female human being.” This is indisputable, isn’t it?

Furthermore, the entry also addresses more nuanced discussions surrounding gender in society, which add depth.

Claiming that we’ve turned into some sort of radical leftist organization is simply misguided. Of course, there are areas worthy of refinement. At times, you may examine an article and feel it’s unjust towards one party, and these instances require critical reflection and effort.

The solution lies in engaging more individuals. I would welcome more compassionate and thoughtful individuals who recognize bias in Wikipedia articles to realize that contributions stem from source material, rather than assuming it’s the work of some radical activist ready to block dissenters.

While certain perspectives may lack representation, we can incorporate them and work toward a more balanced viewpoint.

SF: As reliance on AI for information grows, could Wikipedia face obsolescence?

JW: I hesitate to say “never,” as the future of technology is unpredictable. However, at present, we don’t foresee a significant impact in that regard.

A Pew Research study indicates that Wikipedia appears in about 3% of the top 10 results in standard Google searches, whereas Google’s AI summaries link to Wikipedia approximately 6% of the time.

This dynamic means Wikipedia is frequently referenced in Google AI summaries, although fewer users are inclined to click those links. We’re not overly concerned about clicks, but it remains a trend to monitor.

Personally, I utilize AI extensively and have discovered that its strengths lie in scenarios that wouldn’t typically generate interest on Wikipedia.

Forty years ago, I would have assumed that the first AI able to write in English would be dull and purely factual, merely regurgitating information. Surprisingly, I find that AI excels in creative brainstorming. It’s impressively effective.

Jimmy Wales was the first individual to edit Wikipedia, writing “Hello, World!” right after its launch in 2001. – Credit: Getty

SF: Are you concerned that Wikipedia’s biases could influence the AI models trained on its extensive content?

JW: Absolutely. This is a crucial focus, particularly for those developing AI models.

From what I’ve observed, the largest data sources for most advanced language models (LLMs) are Wikipedia and Reddit. While both are valuable, they have inherent limitations, particularly since both are predominantly male-dominated.

We are striving for awareness, as Wikipedia prioritizes neutrality. Yet, if we’re not vigilant, we risk unintentionally reinforcing existing biases.

At the same time, LLMs can be trained and directed, making it feasible to envision an AI continuously navigating through Wikipedia, identifying biases, and flagging articles in need of revision.

If utilized appropriately, this process could highlight instances where, for example, articles about male Nobel Prize-winning economists mention their families, while articles about female winners do not. Such insights are intriguing and may go unnoticed.

This conversation has been condensed for brevity and clarity.

Archaeologists Unearth 2.75 Million-Year-Old Stone Tools in Kenya

Archaeologists have unearthed Oldowan stone tools across three distinct archaeological layers at the Namorotuknan site, dated to roughly 300,000 years (2.75 million to 2.44 million years ago) within the Koobifora Formation in northeastern Turkana Basin, Marsabit District, Kenya. This discovery, indicating careful selection of rock materials, points to the sustained practice of toolmaking across epochs.

A 2.58 million year old stone tool excavated from the Namorotuknan ruins in Kenya. Image credit: Brown others., doi: 10.1038/s41467-025-64244-x.

The initial phases of toolmaking, which date back over 3 million years, emphasize percussion techniques that are prevalent in the human lineage and shared with other primates.

The practice of tool use associated with extractive foraging continues to be a notable aspect of certain modern primate species.

The earliest structured creation of sharp stone tools, referred to as Oldowan, has been documented at hominin sites in eastern Africa: Lady Gerar and Gona in the Afar Basin (2.6 million years ago), Ethiopia, and Nyayanga in western Kenya (2.6 to 2.9 million years ago).

Professor David R. Brown, an anthropologist at George Washington University and the Max Planck Institute for Evolutionary Anthropology, along with his team, discovered stone tools across three archaeological horizons at the Namorotuknan site, estimated to be 2.75 million years ago, 2.58 million years ago, and 2.44 million years ago.

“This site tells an extraordinary story of cultural continuity,” Professor Brown remarked.

“What we observe is a long-standing tradition of technology rather than a singular innovation.”

“Our findings imply that tool usage might have been a more widespread adaptation among our primate ancestors,” stated Dr. Susana Carvalho, science director at Gorongosa National Park in Mozambique.

“Namorotsukunan offers a unique perspective into a transforming world: flowing rivers, fierce fires, expanding arid regions, and resilient tools.”

Stone tools discovered at the Three Horizons site at the Namorotuknan site in Kenya. Image credit: Brown others., doi: 10.1038/s41467-025-64244-x.

“For 300,000 years, the same tools have endured, possibly revealing the origins of our fundamental habit of using technology to adapt to change,” remarked Dr. Dan V. Parc Laurier, a researcher at GeoEcoMar, Utrecht University, and the University of São Paulo.

“Early humans showed remarkable consistency in creating sharp stone tools, reflecting advanced technology and knowledge handed down through numerous generations.”

Researchers have utilized volcanic ash dating, ancient sediment magnetic signals, chemical signatures in rocks, and microscopic plant remains to construct a broad narrative of climate change, providing context for the influence of technology on human evolution.

These toolmakers managed to persevere through significant environmental transformations. Their innovative technology facilitated new dietary practices, including the consumption of meat, transforming challenges into survival advantages.

“These discoveries indicate that humans had already mastered the creation of sharp stone tools by approximately 2.75 million years ago, suggesting that the inception of Oldowan technology is older than previously believed,” stated Dr. Nigas Baraki, a researcher at George Washington University.

Dr. Francis Forrest, a researcher at Fairfield University, added: “At Namorotuknan, cut marks connect stone tools with carnivory, indicating a diverse diet that thrived amidst shifting landscapes.”

“The record of plant fossils narrates a fascinating tale: the landscape transitioned from rich wetlands to fire-prone arid grasslands and semi-deserts,” noted Dr. Rahab N. Kinyanjui, a researcher at the National Museum of Kenya and the Max Planck Institute for Geoanthropology.

“Despite changes in vegetation, the production of tools remained consistent. This reflects resilience.”

Discovery of a New Shell-Producing Sea Anemone Species in Japanese Waters

A newly identified species of hermit crab-associated sea anemone, Paracalliactis, has been described by a group of marine biologists from Japan and Australia. This crab creates and maintains a distinctive shell-like structure known as a carcinodecium, which enhances the living space for its hermit crab host.

Paracalliactis. Image credit: Yoshikawa et al., doi: 10.1098/rsos.250789.

Paracalliactis is the ninth recognized species within its genus, Paracalliactis.

The genus previously included eight species, one of which was unverified; Involves Paracalliactis and one yet-to-be-described species inhabit shells occupied by hermit crabs.

Most Paracalliactis species thrive on the deep-sea floor (at depths of approximately 200 to 4,700 meters), while Paracalliactis rosea and Paracalliactis sinica are noted at varying depths from shallow to deep (50–3,000 m and shallow depths of 39–40 m, respectively).

“Our findings indicate that even simple organisms like sea anemones can exhibit unexpectedly complex behaviors,” stated the first author, Dr. Akihiro Yoshikawa, a researcher at Kumamoto University.

“The capacity of animals to construct shell-like structures offers intriguing insights into how they navigate and perceive their environment.”

The Paracalliactis hermit crabs have been found inhabiting the shells of Oncopagurus monstrosus, which resides at depths ranging from 200 to 500 meters along the Pacific coast of Mie and Shizuoka prefectures.

Unlike typical sea anemones, which lack a hard skeleton, this species secretes a carcinogen that fortifies and enlarges the crab’s shell.

The research team’s stable isotope analysis indicated that the sea anemones derive a portion of their nutrition from organic particles and crab feces, demonstrating an unusual yet effective recycling method on the deep sea floor.

Additionally, 3D imaging using micro-CT scans revealed that sea anemones attach to their shells in a consistent, unidirectional manner, potentially linked to both feeding and shell formation.

Consequently, hermit crabs gain the advantage of increased body size through this association, underscoring a true symbiotic relationship between the two species.

“Our study provides the first quantitative evidence of mutualism within the carcinogen-forming context, illustrating a remarkable case of deep-sea symbiosis and hypothesizing how mutual benefits evolve over time, fostering the development of carcinogen-forming abilities and species-specific mutualisms,” the authors concluded.

Their paper was published on October 22nd in Royal Society Open Science.

Orange Lichen Aids Paleontologists in Locating Dinosaur Fossils

Lichens, comprising symbiotic fungi and algae (and/or cyanobacteria), are crucial ecological components that inhabit various substrates, including fossils. A recent study highlights their role as biological indicators of fossils in western North America, and demonstrates that they can be identified through remote sensing techniques.

Preferential colonization of dinosaur bones by lichens. Image credit: Pickles et al., doi: 10.1016/j.cub.2025.09.036.

Dr. Brian Pickles from the University of Reading noted, “This research showcases how extant organisms can assist in uncovering ancient life forms.”

“It’s fascinating to realize that these lichens, which essentially represent miniature ecosystems, thrive on the remains of dinosaurs that went extinct over 75 million years ago.”

“Utilizing drone technology to identify spectral signatures in lichens could transform how paleontologists search for fossils.”

In their research, Dr. Pickles and his team identified two lichen species, Rusabschia elegans and Xanthomendoza trachyphylla, which colonized 50% of exposed fossil bones while affecting less than 1% of nearby rock fragments.

This preference can be attributed to the alkaline, calcareous, and porous nature of dinosaur bones that these lichens favor.

“Although the tendency of lichens to thrive on fossil bones has been observed for decades, it has never been quantitatively assessed until now,” stated Dr. Caleb Brown, a researcher at the Royal Tyrrell Museum of Paleontology.

“During our first encounter with a high concentration of exposed fossil bone, such as in a bone bed, our attention often shifts from the bones themselves to the vibrant orange lichen ‘meadows.’

The researchers deployed a drone fitted with specialized sensors to pinpoint lichen-colonized fossils from aerial imagery boasting a resolution of 2.5 cm.

Lichens reveal distinct spectral characteristics, exhibiting lower reflectance in blue wavelengths and increased reflectance in the infrared spectrum.

This innovative method presents considerable benefits for exploration in paleontology, particularly in remote locations where conventional ground surveys are challenging.

This strategy could expedite fossil discoveries while minimizing field expenses and ecological impacts.

The findings are rooted in decades of anecdotal observations made by paleontologists.

In 1980, paleontologist Darren H. Tanke observed that the orange pigmentation of lichens on centrosaurus bones might soon be detectable via satellite. The potential for locating bones using aerial drone technology appears more achievable than ever.

“This drone study sets the foundation for employing aircraft and satellites to map larger expanses,” remarked Dr. Derek Peddle, a researcher at the University of Lethbridge.

“Our newly developed lichen index will aid in fossil identification across vast terrains.”

“It’s exhilarating to merge our imaging technology with the expertise of this international team to enhance dinosaur discovery through remote sensing of lichens.”

The team’s publication appears in this week’s issue of Current Biology.

Trump Reappoints Billionaire Jared Isaacman as NASA Head

On Tuesday, President Donald Trump revealed his intention to renominate billionaire entrepreneur Jared Isaacman to head NASA, just months after abruptly removing Isaacman’s name from consideration in May.

“Jared’s enthusiasm for space, his astronaut experience, and his commitment to advancing exploration and unlocking the secrets of space make him the perfect candidate to guide NASA into a new and daring era,” stated President Trump. View on Truth Social.

Should he be confirmed, Isaacman would succeed Transportation Secretary Sean Duffy, who has been serving as interim administrator of the space agency since July.

At 42, Isaacman is considered somewhat of an outsider for leading the space agency. As the founder and CEO of payment processing company Shift4, he has never held a position with NASA or the federal government.

Nonetheless, he has completed two spaceflights on commercial SpaceX missions, having personally financed both endeavors for undisclosed amounts.

Trump initially nominated Isaacman in December 2024 but retracted his nomination five months later, citing a “thorough review of our existing relationship.” Details were scarce, although some Republicans expressed concern over Isaacman’s past contributions to Democratic campaigns.

If confirmed, Isaacman would take charge of NASA during a time of significant turmoil for the agency. Like other federal departments, NASA has seen major cuts in funding and personnel as part of the Trump administration’s downsizing strategies.

Since Trump’s return to office, NASA has reduced its workforce by about 20%, including over 2,000 senior positions. Last month, the Jet Propulsion Laboratory announced a reduction of 550 jobs, approximately 10% of its workforce.

Additionally, space agencies are bracing for potential budget cuts, as President Trump’s proposed budget indicates a reduction of more than $6 billion (roughly 24%) in NASA funding. With the ongoing government shutdown, many uncertainties surrounding NASA’s future remain.

The situation is complicated by a renewed space race between the U.S. and China, both vying to establish a sustained human presence on the moon. NASA aims to land astronauts by 2027, although delays are likely. Conversely, China has set its sights on landing its astronauts on the moon by 2030.

Elon Musk, founder and CEO of SpaceX and once an ally of Trump, had shown support for Isaacman’s initial nomination. Trump’s choice to withdraw Isaacman’s nomination coincided with a public dispute between Musk and the president.

Trump’s announcement of Isaacman’s renomination comes just weeks after Musk criticized Duffy on the social media platform X, which he owns.

The interim administrator of NASA revealed plans to open SpaceX’s current lunar lander contract to bids from competitors, sparking Musk’s frustration.

In 2021, SpaceX secured a $2.9 billion contract to use its Starship rocket system for NASA’s Artemis III mission, scheduled for 2027. However, Duffy indicated that SpaceX is falling behind and the government aims to foster competition.

Musk expressed his dissatisfaction with Duffy’s remarks, referring to him as a “Sean dummy” and accusing the acting administrator of undermining NASA.

SpaceX’s operations are closely linked to NASA, as the agency depends on Musk’s company for the transportation of astronauts and cargo to the International Space Station, along with upcoming lunar missions.

Coronavirus Poses Greater Heart Disease Risk for Children Than Vaccination

Vaccination against covid-19 is safer than infection

Recent findings highlight that vaccinating children is more beneficial than exposing them to the coronavirus. A comprehensive study involving nearly 14 million children revealed that the likelihood of experiencing serious, albeit uncommon, side effects related to the heart and blood vessels was considerably greater following an infection compared to a vaccination.

Specifically, children aged 5 to 18 experienced 17 additional infections per 100,000 with inflammatory conditions such as Kawasaki disease in the six months after contracting SARS-CoV-2, as opposed to other periods. Conversely, among children first vaccinated with the Pfizer/BioNTech mRNA vaccine, infections per 100,000 dropped by almost two.

Myocarditis, which is inflammation of the heart muscle, resulted in over two extra cases per 100,000 individuals in the six months post-infection. In comparison, there was less than one additional case among vaccinated individuals, indicating that the risk of myocarditis is more than double following infection relative to vaccination.

A report highlighting a new coronavirus infection causing myocarditis has been made known. As early as April 2020, reports began surfacing even after vaccinations commenced in December. Vaccines associated with myocarditis tend to present milder symptoms, particularly in young men, and most individuals recover swiftly.

The uncommon side effects of this vaccine have garnered substantial media focus and stirred significant concern, contributing to delays in introducing routine childhood vaccinations in the UK until April 2022.

The latest findings reinforce earlier research indicating that vaccinated children face a lower risk of myocarditis compared to their unvaccinated peers, despite the rarity of this side effect. A majority of children contracted the virus, placing them at an elevated risk of adverse effects.

“It’s important to note that severe complications are highly uncommon among children and adolescents in general,” states Angela Wood from Cambridge, UK, a part of the HDR UK regional network. “Nevertheless, evidence suggests that the risk is generally higher following COVID-19 compared to vaccination.”

Wood’s team evaluated data from the UK’s National Health Service (NHS) encompassing approximately 14 million children under 18 from January 2020 to December 2021. During the latter half of this timeframe, 3.9 million children received the Pfizer/BioNTech vaccine, while 3.4 million were diagnosed with COVID-19 for the first time. Subsequent periods could not be analyzed due to insufficient testing.

This approach does have its limitations. For instance, the data does not indicate whether children who experienced these complications made a full recovery, and many mild COVID-19 cases amongst children may not have been formally recognized. “However, despite these constraints, the scale of the data and the comprehensive connection across all NHS data instills great confidence in our overall conclusions today,” says Wood.

“It’s crucial to understand that findings relevant to the strain of the coronavirus prevalent during the peak of the pandemic may differ for the current strain,” advises William Whiteley from the University of Edinburgh, UK, who was not involved in the study. His team previously reported that COVID-19 vaccines reduce the risk of heart attacks and strokes for at least six months post-vaccination.

The fact that nearly all individuals, apart from very young children, now possess some level of immunity to COVID-19 means they may respond differently to both booster shots and reinfections, according to team members including Peer Hardelid from University College London. “Ongoing research is essential,” she emphasizes.

OpenAI Enters $38 Billion Cloud Computing Agreement with Amazon

OpenAI has secured a $38 billion (£29 billion) agreement to leverage Amazon’s infrastructure for its artificial intelligence offerings, part of a broader initiative exceeding $1 trillion in investments in computing resources.

This partnership with Amazon Web Services provides OpenAI with immediate access to AWS data centers and the Nvidia chips utilized within them.

Last week, OpenAI CEO Sam Altman stated that the company is committed to an investment of $1.4 trillion in AI infrastructure, highlighting concerns over the sustainability of the expanding data center ecosystem, which serves as the backbone of AI applications such as ChatGPT.

“To scale frontier AI, we need large-scale, dependable computing,” Altman remarked on Monday. “Our collaboration with AWS enhances the computing ecosystem that fuels this new era and makes sophisticated AI accessible to all.”

OpenAI indicated that this deal will provide access to hundreds of thousands of Nvidia graphics processors for training and deploying its AI models. Amazon plans to incorporate these chips into its data centers to enhance ChatGPT’s performance and develop OpenAI’s upcoming models.

AWS CEO Matt Garman reaffirmed that OpenAI is continuously pushing technological boundaries, with Amazon’s infrastructure forming the foundation of these ambitions.

OpenAI aims to develop 30 gigawatts of computing capacity, enough to supply power to approximately 25 million homes in the U.S.

Recently, OpenAI declared its transformation into a for-profit entity as part of a restructuring effort that values the startup at $500 billion. Microsoft, a long-time supporter, will hold roughly 27% of the new commercial organization.

The race for computing resources among AI firms has sparked worries among market analysts regarding financing methods. The Financial Times reported that OpenAI’s annual revenue is approximately $13 billion, a figure starkly contrasted by its $1.4 trillion infrastructure expenditures. Other data center deals OpenAI has entered include a massive $300 billion agreement with Oracle.

During a podcast with Microsoft CEO Satya Nadella, Altman addressed concerns regarding spending, stating “enough is enough” when prompted by host Brad Gerstner about the disparity between OpenAI’s revenue and its infrastructure costs.

Altman claimed that OpenAI generates revenue “well above” the reported $13 billion but did not disclose specific figures. He added: “Enough is enough…I believe there are many who wish to invest in OpenAI shares.”

Analysts at Morgan Stanley have forecast that global data center investment will approach $3 trillion from now until 2028, with half of this spending expected to come from major U.S. tech firms, while the remainder will be sourced from private credit and other avenues. The private credit market is an expanding segment of the shadow banking industry, raising concerns for regulators such as the Bank of England.

Unraveling Polycystic Ovary Syndrome: New Insights into the Genetic Causes of PCOS

Visual representation of polycystic ovary syndrome showing enlarged ovaries

Science Photo Library / Alamy

Recent research has begun to shed light on the genetics behind polycystic ovary syndrome (PCOS), paving the way for potential new therapies.

PCOS affects up to 20% of women, leading to disrupted ovarian function characterized by at least two of the following: irregular or absent periods, elevated male hormones like testosterone, and the accumulation of immature eggs within cyst-like ovaries. Consequently, it can result in fertility challenges.

While the exact causes remain unclear, PCOS is believed to correlate with changes in the gut microbiome and hormonal imbalances during prenatal development. The condition also appears to have a hereditary component, with studies indicating that 70% of the risk is genetic. However, researchers have only pinpointed about 25 genetic mutations impacting sex hormone production and ovarian function, explaining roughly 10% of an individual’s risk.

To address this knowledge gap, Qiao Shigang and colleagues at Shandong University in Jinan, China, conducted a genomic study involving over 440,000 women from China and Europe, out of which 25,000 were diagnosed with PCOS, marking the largest gene analysis related to the condition to date.

The researchers discovered 94 genetic variants that appear to contribute to PCOS risk, with 73 being previously unrecognized. Notably, one mutation affects the gene responsible for the mitochondrial ribosomal protein S22, essential for mitochondrial function, an area that Zhao points out has connections in earlier studies discussing the link between PCOS and mitochondrial dysfunction.

Another newly identified variant impacts sex hormone-binding globulin, a protein that moderates the activity of sex hormones and is often found at reduced levels in women with PCOS.

Several of the remaining variants influence the function of granulosa cells in the ovaries, responsible for producing estrogen and progesterone and aiding in egg development during the menstrual cycle. This supports the hypothesis that PCOS is genetically influenced by fluctuations in sex hormone levels, according to Zhao.

In summary, the research indicated that these 94 mutations account for around 27% of the risk variation in PCOS among European participants and about 34% in the Chinese cohort.

“This study is significant because it enhances our understanding of the genetic factors associated with this condition,” remarks Elisabeth Stenner-Victorin from Karolinska Institutet, Sweden. Furthermore, it underscores the necessity of including diverse ancestral backgrounds in PCOS genetic research, according to Zhao.

Ultimately, the team identified medications that could modify the pathways affected by the recognized mutations. Some of these, like clomiphene, are already used for PCOS treatment; they stimulate ovulation which is often hampered by the syndrome. Additionally, the team discovered that betaine—sometimes utilized for homocystinuria treatment—might also benefit PCOS patients. Future studies using mice exhibiting PCOS-like symptoms could explore this treatment potential.

“Current treatments focus on alleviating symptoms, as there aren’t any medications that can cure PCOS,” states Stenner-Victorin. Typical interventions include clomiphene, contraceptive pills to manage periods, and metformin, a type 2 diabetes medication that may enhance fertility. However, effectiveness varies among individuals. “Identifying genetic clusters that affect PCOS risk will be essential for developing more targeted treatment strategies for these women,” she adds.

Fascinating Tale of the Supreme Cosmic Principle

Where did the speed of light come from and why is it so stubborn?

NASA, ESA, CXC, SSC

This excerpt is from the Lost in Space-Time newsletter, where we share intriguing ideas every month. You can Click here to register for Lost in Time and Space.

If you’ve taken a physics class, you likely have “memorable” instances of measuring light speed, spending hours setting mirrors, lenses, and light sources just right to achieve the result: just under 300 million meters per second. This figure is a fundamental constant in physics and vital for comprehending the universe.

When observing space, light is our primary resource. While we have other means, like gravitational waves, they currently offer limited insights, so I might be exaggerating a tad. Almost all advancements in astronomy and cosmology derive from collecting light that has traversed from the edge of reality over millions, or even billions, of years. Light from our nearest star takes over four years to reach us. The duration it takes for light to travel may be one of the most practical yet least intuitive aspects of physics.

Humans have debated light’s speed long before we truly understood light itself. For centuries, many intellectuals believed that the glowing in certain animals’ eyes at particular angles indicated they emitted light, resembling a lantern. Nonetheless, they debated whether light traveled instantaneously or required time to propagate, a question not thoroughly tested until the 17th century.

An early endeavor to quantify it involved placing a lantern at a distance and measuring the time difference between it lighting up and the observer seeing the light. This method proved ineffective (Galileo and his peers failed to attain conclusive measurements because the lantern was too close), leading scientists to explore more complex and accurate approaches. The first effective instrument was developed in 1675 by Ole Römer while measuring Jupiter’s moon Io’s orbital period. He observed that the period seemed to vary as the distance from Earth to Jupiter fluctuated, which seemed perplexing. Why would Io’s orbit correlate with Earth’s positioning? The only variation was the time it took for light to travel from Io to Earth, diminishing as the two grew closer. A colleague, Christian Huygens, calculated that light’s speed was around 220,000,000 meters per second. Although this estimate lacked precision due to unknown earthly movements, it established a foundation for later refinements. By the early 18th century, measurements were within a few percent of the current consensus of light’s speed in vacuum: 299,792,458 meters per second.

This prompts two inquiries: Why is the speed of light seemingly arbitrary, and why is there a speed limit at all? The first question is straightforward, linked to our units. Meters and seconds (or miles and hours) originated from human experiences. For instance, a mile equals 1,000 steps and has no relation to fundamental constants. The second question is more complex, entwined with special relativity.

The answer lies in perhaps the most recognizable equation: e=mc2. This equation implies that energy and mass can be interchanged. When objects move at extremely high or relativistic speeds, I like to think of them possessing momentum, blending mass and velocity. To increase an object’s speed, we must continually supply more energy. A massive object achieving light speed would require infinite momentum, equating to infinite energy or mass. This situation is unattainable. As an object nears light speed, its mass escalates, making further acceleration unfeasible. Light, having no mass, circumvents this dilemma.

Moreover, special relativity illustrates that an outside, stationary observer would perceive something quite unusual. When an object travels at relativistic speeds, time appears to slow down from an external viewpoint. If I were moving away from you at 99% of light speed, I’d observe my aging decelerating. This phenomenon is termed time dilation. Concurrently, another effect, length contraction, would have you notice that I’m shrinking increasingly as I accelerate. From my frame of reference, I wouldn’t perceive time slowing down or my stature diminishing, but from your outlook, the closer I get to light speed, the shorter and more ageless I appear.

Herein lies a paradox: if I somehow reached light speed, time would seemingly stop for an outside observer as my height approaches zero. I would cease to exist, along with time and space. Luckily, the laws of physics preclude that scenario. Only massless entities can attain that speed limit: photons, gluons, and gravitational effects. Nothing surpasses light speed through space and time.

Rather than feeling disheartened by the universe’s speed limitations, we should celebrate them. The speed of light carries a crucial consequence: it underpins the whole notion of causality. All physics, and our comprehensive understanding of everything, hinges on the principle that effects always follow causes, never the other way around.

Consider this: as I approach light speed, you observe my time slowing down. It will cease entirely when I attain light speed. Should I exceed light speed, from your perspective, I’d be reversing time. If I transmitted a signal faster than light, a hypothetical message defying physics, you’d receive it before I sent it. Absent a universal speed limit, discerning which events caused which effects would be impossible, rendering the universe largely incomprehensible.

Finally, here’s a thought-provoking notion: if all signals require time to travel, and time progresses variably in frames of reference moving at different speeds, what does simultaneous meaning? If I wink at my reflection, the reflected wink arrives slightly later than my physical action, due to light needing to bounce off my face, towards the mirror, and back into my eyes. If two events simultaneously occurred across the universe, I must ask, “By whose standard?” Depending on the distance separating two locations, event 1 might have occurred first for one observer, while event 2 happened prior to event 1 for another. There is no objective simultaneity, no definitive “same time.” This reality stems solely from light’s finite speed. Fascinating, right?

Extended Use of Melatonin Linked to Negative Health Outcomes

An analysis of five-year health data from over 130,000 adults suffering from insomnia who had been taking melatonin for at least a year indicated that these individuals were at an increased risk of being diagnosed with heart failure, needing hospitalization for the condition, or dying from any cause.



Long-term use of melatonin supplements, often utilized to enhance sleep and treat insomnia, was linked to a higher risk of heart failure diagnosis. Image credit: Gemini AI.

Melatonin is a hormone naturally generated by the pineal gland, aiding in the regulation of the sleep-wake cycle.

Levels of melatonin rise in darkness and fall during daylight.

Synthetic hormones, chemically identical to natural melatonin, are frequently prescribed to address insomnia (difficulties in initiating or maintaining sleep) and jet lag.

This supplement is widely available over-the-counter in several countries, including the United States.

In the recent study, researchers identified individuals with long-term melatonin use (defined as over a year recorded in electronic health records) as part of the melatonin group.

Conversely, those without any recorded use of melatonin in their medical history were classified as the non-melatonin group.

“The perception that melatonin supplements are harmless may not be accurate,” asserts Dr. Ekenedirichukwu-Nnadi from the State University of New York Downstate/Kings County Primary Care.

“If validated, our findings could significantly impact how healthcare providers counsel patients regarding sleep aids.”

Although melatonin supplements are marketed as safe sleep aids, there is insufficient evidence regarding their long-term cardiovascular safety, prompting researchers to investigate whether melatonin use elevates the risk of heart failure, particularly in chronic insomnia patients.

Heart failure, which arises when the heart is unable to pump sufficient oxygenated blood for the body’s organs to operate effectively, affects 6.7 million adults in the United States, according to the American Heart Association’s 2025 Heart Disease and Stroke Statistics.

The researchers utilized a large international database to analyze five years of electronic health records of adults with chronic insomnia who had documented melatonin use exceeding one year.

They were compared with colleagues in the database who also suffered from insomnia but did not have melatonin recorded in their medical files.

Participants with a prior heart failure diagnosis or those prescribed other sleep medications were excluded from the study.

The analysis revealed that among insomnia sufferers, those whose records indicated long-term melatonin use (over 12 months) were roughly 90% more likely to develop heart failure over five years compared to non-users (4.6% vs. 2.7%, respectively).

Similar outcomes (an 82% higher incidence) were observed for individuals who received at least two melatonin prescriptions spaced 90 days or more apart.

In a further analysis, researchers noted that melatonin users were nearly 3.5 times more likely to be hospitalized for heart failure compared to non-users (19.0% vs. 6.6%, respectively).

Melatonin group participants were almost twice as likely to die from any cause over a five-year duration compared to those in the non-melatonin group (7.8% vs. 4.3%, respectively).

“Melatonin supplements are generally regarded as a safe, ‘natural’ solution for improving sleep quality, so the consistent and significant rise in serious health issues was unexpected,” stated Dr. Nadi.

“Since melatonin isn’t officially approved for treating insomnia in the U.S., it’s surprising that physicians would prescribe it for more than 365 days,” remarked Dr. Marie-Pierre St-Onge from Columbia University.

“While melatonin is available as an over-the-counter supplement in the U.S., individuals should be cautious about using it chronically without proper guidance.”

The research findings are expected to be presented at an upcoming conference this week at the American Heart Association 2025 Academic Session.

Webb Takes Stunning Images of the Red Spider Nebula.

Utilizing the Near Infrared Camera (NIRCam) aboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have obtained fresh images of the Red Spider Nebula, a prominent planetary nebula located in the constellation Sagittarius.



This web image showcases the Red Spider Nebula. Image credit: NASA/ESA/CSA/Webb/JH Kastner, Rochester Institute of Technology.

The Red Spider Nebula was identified by American astronomer and physicist Edward Charles Pickering on July 15, 1882.

This astronomical object is located roughly 12,420 light-years away from Earth in the constellation Sagittarius.

Commonly referred to as NGC 6537, ESO 590-1, and IRAS 18021-1950, it has an approximate radius of 3.6 light-years.

“Planetary nebulae, like the Red Spider Nebula, form when average stars, such as our Sun, reach the conclusion of their life cycles,” Webb astronomers noted in a statement.

“As these stars expand into cool red giants, they shed their outer layers, propelling them into space and revealing their hot white cores.”

“Ultraviolet radiation from the central star ionizes the ejected material, causing it to emit light.”

“The planetary nebula stage of a star’s lifecycle is both spectacular and brief, lasting only tens of thousands of years.”

“This Webb image displays the central star of the Red Spider Nebula, which shines slightly brighter than the dusty gas web surrounding it.”

In optical images from telescopes such as Hubble, the stars appear faintly blue.

However, in the NIRCam image, it appears red. Webb’s sensitive near-infrared capabilities have unveiled the hot dust enveloping the central star.

“This hot dust likely orbits the central star in a disk-like formation,” the astronomers explained.

“Even though only one star is visible at the nebula’s center, a concealed companion star may exist there.”

“Such a stellar companion could account for the nebula’s shape, including its distinctive narrow waist and broad jets.”

“This hourglass configuration is also observed in other planetary nebulae, like the Butterfly Nebula, which Webb has also recently studied.”

“Webb’s fresh perspective on the Red Spider Nebula reveals, for the first time, the complete extent of the nebula’s extended lobes that resemble the spider’s ‘legs,'” researchers stated.

“These lobes, depicted in blue, are traced by light emitted from H.2, a molecule consisting of two hydrogen atoms bonded together.”

“These lobes, which are visible across NIRCam’s field of view, are shown to be closed, bubble-like structures, each stretching about three light-years.”

“Gas streaming from the core of the nebula has inflated these massive bubbles over countless years.”

“New observations from Webb indicate that gas is also actively being ejected from the nebula’s center.”

“A protracted purple ‘S’ shape at the nebula’s center follows light from ionized iron atoms.”

“This feature illustrates where a fast-moving jet has emerged near the nebula’s central star, colliding with previously ejected material and shaping the nebula’s undulating structure that we observe today.”

Football Manager 26 Review – A Contemporary Simulation for Today’s Gaming World

YYou can picture the home fans belting out their chants at the Stadium of Light. “Top of the league, you’re smiling!” Until this afternoon, your Liverpool squad boasted a five-point advantage at the summit, but in the 82nd minute, they’re trailing by two. You might question where Mo Salah misplaced his finishing skills or why Virgil van Dijk has seemingly forgotten how to tackle. However, this is not on the players; the responsibility lies with you. You fix your gaze on the tactical screen, pondering which of the numerous adjustments could potentially alter the course of this disheartening match.

Football Manager has consistently served as a data-centric alternative to the visually stunning FIFA series (now EA Sports FC), yet the latest versions are beginning to close the visual gap. The 3D rendered match highlights have been revamped using the new Unity engine, and the results are remarkable. Premier League derbies, Champions League finals, and even away clashes in the North East now carry visual significance, despite replays and key moments occasionally dragging on. While you won’t hear fully orchestrated FIFA-style chants ringing throughout the stadium, the atmosphere is tangible, with your imagination filling in the empty spaces.




Specific influences on tactics …Football Manager 26. Photo: Sega

This new engine and enhanced match experience are the most significant indicators of Football Manager’s future direction. Nevertheless, visual improvements go beyond mere aesthetics; they have a substantial effect on tactical decisions. As you observe the match, you can analyze player movements on the field and make real-time adjustments. Yet, data-driven metrics remain crucial when you’re desperately aiming to turn the tide in front of a raucous crowd of 45,000 Mackems. You can also modify your build-up tactics to counter the press or overload one side with overlapping runs. The possibilities are endless, and you’ll be eager to experiment with them all.

The most significant change lies in the differentiation of tactical strategies when in possession versus when not in possession. This marks the most substantial overhaul in a decade and appropriately reflects the intricacies of modern gaming. You can now completely alter formations, rearrange player positions, and issue detailed instructions that vary based on which team controls the ball. Want to switch your full-backs as you enter the final third? Not only can you do this, but they’ll promptly revert to their original positions when Alexander Isak is taken down on the edge of the box.

However, there is a notable teeth problem. Following a year off to transition to a new engine, Football Manager 26 still feels somewhat unrefined. A series of hotfixes have been rolled out to address some of the more glaring bugs, yet several persist, such as duplicated UI elements, secondary players entering the pitch in jerseys, and menu glitches that hinder progress.

Between matches, adapting to the new UI will take some time. Notably, key screens that were once easy to access are now a few clicks away. All the same information is available, just in slightly altered positions (especially with the introduction of a women’s league). Re-learning years of muscle memory can be frustrating, and additional customization options would be beneficial, but this is a minor grievance that will be resolved over time.

Despite these challenges, this is still Football Manager, complete with intricate tactics that will keep you engaged. Thanks to an updated tactic and match engine, it has never been simpler to make the perfect tactical adjustments to stage a dramatic comeback and silence overconfident home fans. Football Manager 26 offers immediate feedback on split-second choices and allows you to envision enduring rivalries that can stretch across several seasons. And the exhilaration of scoring three goals in the final five minutes to triumph over Sunderland is unparalleled.

Football Manager 26 is currently available for £49.99

The Ultimate Texting Blunder: What to Use Instead?

Name: “lol”.

Year: The Oxford English Dictionary featured lol for the first time in 1997.

Don’t confuse: LOL, as in what dogs might do at times.

Is it similar to “laugh out loud”? Yes, but David Cameron once thought it meant “a lot of love,” leading to a big laugh with former Sun and News of the World editor Rebecca Brooks.

I find his comical blunders hilarious. You probably shouldn’t.

Why not? Because those who still smile aren’t considered cool.

Is laughing out loud now forbidden? Yes, using LOL in texts or WhatsApp is no longer in vogue.

Who claims this? According to Gen Z, a Sky Mobile survey revealed that 26% of 18 to 28-year-olds feel offended by “LOL” in messages, making it their second biggest grievance.

What tops the list? Ix’s? A bland response. Closely related is the impatient “??” that appears when one doesn’t get an instant reply to their initial message. Interestingly, 79% admitted to ignoring such messages.

It’s as if I despise myself! In reality, 61% said they feel embarrassed by their texting habits.

I’d probably opt for something simple like a good emoji, just to be safe 👍 However, that often feels off-putting. Likewise, the unsightly monkey 🙈, the awkward grimace 😬, and the happy poop 💩.

Eh! What about the tears of joy emoji 😂? Instead of laughter, is that also passe? It seems to be favored by older generations. Gen Z (and younger) often prefer sending a skull 💀 or a coffin ⚰️.

So die together in sorrow, instead of sharing laughter? That’s correct.

What’s the deal with abbreviations like “hru” and “wyd”? As for me? I’m doing fine. And I’m probably ignoring those queries.

Ruri? Seriously. Research published in the Journal of Experimental Psychology indicates that while abbreviations may save time for senders, they can be perceived as insincere by recipients. It’s a bother for people of all ages and genders.

Goodness, it’s intricate! Keeping up is tough, isn’t it? Believe me, it’s true. There is an ABC News video showcasing children expressing discomfort to their teachers.

“Cringe” is indeed cringe-worthy! And “ick” will likely leave them unsettled.

Are any of these phrases meaningful? I hope individuals can perceive beyond texts and emojis to see the real person. Let’s hope for that! Referring back to the Sky Mobile research, 58% of Gen Z confessed to pondering a breakup because they felt their partner had poor texting manners. Who’s laughing now?

Do tell: “That was clearly ironic (laughs).”

Please avoid statements like: “Happy Valentine’s Day, Samantha, lol!”

COP30: Will the Brazil Summit Revitalize Climate Change Negotiations?

SEI 272284218

Preparatory ministerial meeting in Brasilia, Brazil ahead of COP30

As world leaders converge for the latest United Nations climate change conference a decade after the landmark COP21 summit in Paris, pessimism looms large. With the pivotal 1.5°C target already deemed unattainable and even the more lenient 2°C objective appearing increasingly elusive, the atmosphere is charged with concern.

The United Nations Environment Programme suggests, based on current national commitments, that the world is on track for a temperature rise of 2.3 to 2.5 degrees Celsius this century. Climatologists emphasize that the upcoming 30th United Nations Conference of the Parties in Belem, Brazil, could be crucial in altering the course of global warming, with oceans, forests, and polar ice sheets nearing tipping points. Significant action is essential to assist poorer nations in securing the estimated $1.3 trillion necessary each year by 2030 to transition away from fossil fuels, mitigate climate change, and adapt to its consequences.

Manuel Pulgar Vidal, WWF’s global leader in climate and energy, states, “The climate debate is under serious threat from not just political decisions but also economic, financial, and trade factors.” He adds that this makes the upcoming COP perhaps one of the most consequential since 2009, as vital as Paris but in an entirely different context.

In reality, however, the expectations held by negotiators are muted. The prospect of a groundbreaking multilateral agreement akin to that of Paris seems far-fetched in the current fragmented political landscape.

The previous COP29 held in Baku, Azerbaijan, concluded with disappointing outcomes, as wealthier nations pledged considerably fewer fiscal contributions than poorer counterparts anticipated. Consequently, trust in the COP process has diminished, leading to discussions on whether the existing framework is still viable.

“Private investment is lacking, nations appear to be retreating on their commitments to move away from fossil fuels, and there are no new Nationally Determined Contributions (NDCs) offered,” remarks Claudio Angelo from Brazilian NGO Klima Observatory. “The atmosphere surrounding climate action feels incredibly strained.”

Tensions ignited by trade disputes and geopolitical conflicts have infiltrated climate negotiations, with former President Trump actively opposing climate initiatives. He notably withdrew the U.S. from the Paris Agreement and curtailed efforts to limit fossil fuel use, urging other nations to do the same. On October 17, the International Maritime Organization postponed the formal endorsement of a plan aimed at reducing maritime emissions, incited by Trump’s threats of sanctions against supportive countries.

Economic sluggishness, rising living costs, and a rise in populist sentiments are complicating the implementation of climate-friendly policies. “2025 is shaping up to be the worst year for global climate action,” concludes Angelo.

Europe was initially anticipated to take a leadership role in climate diplomacy following the withdrawal of U.S. support; however, the continent remains divided as defense priorities, trade issues, and escalating energy expenses dominate discussions.

In Brazil, the host nation, President Luiz Inácio Lula da Silva—who campaigned on environmental protection—has approved new highway constructions in the Amazon and oil prospecting in the region, with an eye towards the upcoming elections.

Bringing the COP to Belem is also a contentious choice. This first-ever Amazon COP aims to highlight the stories of those and the forests affected by climate change, underscoring the bold vision necessary for global salvation. The Ministry of the Environment has declared that a greater number of indigenous delegates than ever before will attend COP30.

Nonetheless, many participants regard this decision as imprudent. A shortage of available accommodation has driven up prices, forcing NGOs, diplomats, and businesses to seek alternative sleeping arrangements like tents, shipping containers, or hammocks.

The United Nations also restricts accreditation, leading to concerns that rather than being an “implementing COP,” this one may turn out to be an “empty COP.”

“An organization that had eight certifications last year only secured two this time,” notes Carla Cardenas from the Rights and Resources Initiative, a coalition advocating for land rights for indigenous peoples. Cardenas raised worries that civil society groups aiming to hold leaders accountable may face restrictions in attendance while oil and gas lobbying organizations, which possess larger budgets, remain unaffected.

Ahead of the summit, there are some indications of a positive shift. Fears that not enough leaders would attend to achieve a quorum have lessened, as high-profile figures like Britain’s Keir Starmer decide to make last-minute trips.

Amid declining multilateralism, Brazil, known for its mediating role on the global stage, could serve as an ideal host to unite divergent perspectives within climate diplomacy.

The president’s office is adopting a practical stance in negotiations, indicating that no major headline-making declarations are anticipated this time. Brazil’s focus will likely be on implementing existing agreements rather than chasing media-friendly headlines.

While substantial international breakthroughs in Belém are unlikely, there remains potential for cities, regions, and businesses committed to climate action to step forward, according to Thomas Hale from Oxford University. Groups of states collaborating to announce environmental initiatives could still have a significant influence.

“Countries resistant to change, like the U.S., may stay on the sidelines, but that won’t define where the real action occurs,” he explains. “Although we may not see international decisions made at COP that will move us forward fundamentally, it can still provide a framework for many positive initiatives to arise.”

Incredible Valuations of AI Firms

Greetings! Welcome to TechScape. I’m your host, Blake Montgomery. If you wish to subscribe to our newsletter, please share this email with 5 friends and encourage them to sign up, much like a chain letter promising 5 years of bad luck. This week in news, AI companies have reached astonishing financial highs, with valuations soaring to $5 trillion, a record $100 billion quarterly earnings, and a series of agreements totaling close to $600 billion.

The staggering numbers of the AI boom make criticism challenging.

Last week, Nvidia’s market valuation hit the $5 trillion mark. Just three months earlier, it had become the first company ever to reach a $4 trillion valuation. Similarly, Microsoft joined Apple in hitting the $4 trillion valuation last week. In addition, companies like Meta, Microsoft, Amazon, and Alphabet reported massive quarterly earnings. Notably, Google’s parent company generated $100 billion in its first quarter. Amazon experienced remarkable expansion in its cloud computing sector, leading to a 13% increase in its stock price. However, Meta faced an unexpected tax bill of $16 billion. All major tech firms except Apple have increased their capital spending forecasts, indicating plans to invest billions more in the essential infrastructure that backs AI. These revisions alone add tens of billions to an already staggering total in the hundreds of billions. For instance, Alphabet has projected capital expenditures of $91 billion to $93 billion for next year, an increase from the $75 billion initially stated in February and the revised $85 billion announced in July.

Not to be outdone by its publicly traded competitor, OpenAI has transitioned to a for-profit model and is contemplating an initial public offering with a potential valuation of $1 trillion. The world’s highest-valued startups are actively making deals, including a partnership with Nvidia that involves an investment of $100 billion in OpenAI as of September. Furthermore, Microsoft recently entered a contract with OpenAI for $250 billion in Azure cloud services. Oracle, another cloud services giant, also struck a $300 billion investment agreement with OpenAI in September. On Monday, the creator of ChatGPT announced a $38 billion deal with Amazon Web Services, as OpenAI commits to a staggering total of $588 billion in expenditures over the coming years.

Nvidia is now valued higher than Germany’s total annual economic output projected for 2025, estimated at $4.66 billion. To put this into perspective, Nvidia’s market capitalization surpasses the collective valuation of all German companies, which is expected to be approximately $2.4 trillion in 2024, according to the World Bank. No single company should eclipse the world’s third-largest economy, a nation with 83.5 million residents whose economic landscape supports an entire continent.

Understanding the economics surrounding the AI boom poses significant challenges, hindering straightforward criticism. How should one respond to such overwhelming data? Even the keenest analyses can feel dwarfed by the magnitude of a billion-dollar data center. The scale of these figures defies comprehension; there’s hardly a personal context with which to relate. How do we consider a spending plan of $91 billion? What does it mean to make choices in the realm of hundreds of billions? It’s bewildering. Describing Meta’s earnings as “mixed” feels odd, yet that’s the assessment from Wall Street experts.

The boom has seen billions circulating in transactions between these corporations, raising red flags regarding inflated valuations and financial risk. If one entity stumbles, a domino effect could ensue, potentially dragging the U.S. economy down with it. Nonetheless, these companies show no signs of diminishing their collective enthusiasm.

On the populist front, critics argue that AI has failed to establish any significant use cases beyond something as trivial as assisting with homework. Regardless of how many jobs a CEO might eliminate, replacements will remain inadequate. Approximately 95% of AI pilots that companies have undertaken have faltered, as MIT researchers discovered in August.

The economic magnitude of the AI boom is unfathomably vast, corresponding with its digital scale. Large language models like ChatGPT and Claude Sonnet operate partially through parameters—variables that help the model predict subsequent words. These invisible adjusters can modulate responses by the hundreds of billions, with projections indicating that GPT-5 could reach into trillions.

The physical ramifications of AI mirror the considerable economic scale of this technology. Dara Kerr, a technology reporter for the Guardian, recently reported from the Tahoe-Reno Industrial Center, which houses the largest data center in the nation along with several smaller establishments. She detailed its extraordinary scale:

The Tahoe-Reno Industrial Center stretches from Interstate 80 to the mountains of the arid Nevada desert. This vast complex encompasses tens of thousands of acres and houses roughly 200 companies involved in logistics, fulfillment, and data center technology, including Google, Microsoft, and Tesla. Some firms maintain multiple data centers spanning several times the length of a football field throughout desert valleys. This industrial area occupies 65% of the county’s land, creating a scale that’s nearly incomprehensible.

You can now wager on American elections by contributing to the President of the United States




US President Donald Trump
Photo: President Donald Trump via Truth Social and Reuters

Donald Trump’s Truth Social is collaborating with Crypto.com to facilitate betting on election outcomes, as announced by its parent company last week. Trump Media and Technology Group is set to launch a “Truth Prediction” feature allowing users to “trade predictive contracts on major events and milestones, ranging from political elections to changes in interest rates, inflation, commodity prices, and significant sports events,” although a launch date remains uncertain.

TMTG Director Devin Nunes stated regarding the feature, “For too long, elites have strictly controlled these markets. With Truth Prediction, we’re democratizing information, enabling regular Americans to harness collective wisdom and converting free speech into actionable foresight.” Ironically, Nunes criticizes the “global elite” from a position of notable power within the government.

There’s something unsettling about this arrangement, as if the contender in a match is simultaneously the bookmaker. Mr. Trump, as President, invites voters to invest in his campaign while implementing policies that directly impact the interest rates users can wager on. As he flirts with the notion of an unprecedented third term, does the American public want to take bets on his potential to achieve it?

Even creating the truth prediction feature seems like a dubious endeavor. Crypto.com has contributed $11 million to Trump’s initiatives, as reported by the Financial Times. Additionally, the U.S. Securities and Exchange Commission closed its investigation during Trump’s administration while the company sought banking authorization from regulators. Trump Media and Technology Group signed a substantial deal to acquire billions of dollars’ worth of Kronos, the token associated with Crypto.com.

Gambling has become increasingly ingrained in American culture, with trading on election outcomes only legalized last year. A recent analysis by the Financial Times observed that the betting volume on prediction markets like Karshi averages $1 billion each week. This trend initiated with sports betting, which has reached unprecedented levels. My colleague Brian Armen Graham discussed the fallout from a scandal that shook the professional basketball world before Halloween, dubbed Operation No Bet, leading to the arrest of NBA players, coaches, and dozens of others.

The NBA gambling scandal marks the peak of a lengthy relationship between professional leagues and the massive gambling industry, which has transitioned from partnership to controversy. This represents the most significant corruption crisis in Major League Baseball following the legalization of gambling in numerous U.S. states and serves as a clear reflection of how embedded gambling has become within professional sports.

When will politics face its own “no-bets strategy”?

Gel That Restores Tooth Enamel Could Help Prevent Decay

Enamel shields teeth from harm, yet can be easily compromised

Agrobacter/Getty Images

The gel incorporates compounds found in saliva to aid in the repair and regeneration of tooth enamel while preventing cavity formation that necessitates fillings.

Enamel, the tough and glossy outer layer of teeth, safeguards the sensitive inner part from wear, acids, and bacteria. “Enamel serves as your initial defense; when it starts to deteriorate, tooth decay accelerates,” explains Dr. Alvaro Mata from the University of Nottingham, UK. Since enamel does not self-repair, methods like fluoride varnishes and remineralizing treatments merely prevent further deterioration.

In search of a solution, Mata and his team engineered a gel that contains a modified protein designed to mimic amelogenin, which is vital for enamel growth in early development.

Tests revealed that applying the gel to human teeth under a microscope in a calcium and phosphate solution—the essential components of enamel—yielded a thin, robust layer that persisted for weeks, even during brushing.

This gel establishes a framework that utilizes calcium and phosphate to fill imperfections and encourage the organized development of new crystals in the enamel beneath the gel layer, even if a significant portion of the dentin is exposed.

“The gel successfully grew crystals epitaxially, meaning it mirrored the crystal orientation of the existing enamel,” Mata states.

This alignment allows the new growth, achieving thicknesses of up to 10 micrometers, to integrate with the underlying natural tissue, reconstructing both the structure and functionality of the enamel. “Growth occurs within a week,” remarks Mata. The method proved effective not only with the specific solution employed but also with donated saliva, which naturally contains calcium and phosphate.

A comparable approach was noted in 2019, but it resulted in a thinner coating, only partially restoring the inner enamel structure.

Clinical trials on humans are set to commence early next year. Mata is also establishing a company named Mintech-Bio, hoping to launch its first product by late 2026 for use by dentists.

Most Intense Black Hole Flare Recorded as Massive Star Gets Torn Apart

A supermassive black hole in the process of engulfing a massive star

California Institute of Technology/R. Hurt (IPAC)

Astronomers have made an astounding discovery of the brightest flare ever observed from a supermassive black hole. This flare was so intense that it can only be attributed to a tidal disruption event (TDE), where a colossal star was torn apart by a distant galaxy’s black hole, unleashing an extraordinary burst of energy that is still resonating.

Originating from an active galactic nucleus (AGN) — a supermassive black hole at the core of a galaxy consuming matter — this event is approximately 20 billion light-years from Earth, marking it as one of the most distant TDEs recorded. Notably, many TDEs remain undetected in AGNs due to the fluctuating brightness near these active black holes, which obscures the distinction between a TDE and other phenomena.

“For the last 60 years, we have understood AGNs to be highly volatile, but we lacked clarity about their variability,” explains Matthew Graham from the California Institute of Technology. “Currently, we are aware of millions of AGNs, yet their variability remains largely a mystery.” The event, dubbed “Superman” due to its remarkable brightness, holds the potential to unravel some of these cosmic enigmas.

Initially identified in 2018, astronomers speculated that Superman might merely be a bright explosion from a relatively nearby galaxy. It wasn’t until 2023 that subsequent observations unveiled its true distance and revealed that its brightness was significantly more intense than initially estimated.

This first flare enhanced AGN visibility to over 40 times greater and was 30 times more powerful than any other flare recorded from AGN. Graham and his research team concluded that the most plausible explanation is the disintegration of a massive star, possibly over 30 times the mass of the Sun.

All active supermassive black holes are surrounded by a region of infalling material known as an accretion disk. The matter density in this area is expected to yield substantial stars, although they have never been directly observed. “If our interpretation of this as a TDE is correct, it substantiates our hypothesis regarding the existence of these massive stars in such environments,” noted Graham.

“We once believed that active supermassive black holes simply housed gas disks that meandered about. However, this scenario is much more dynamic and active,” he adds. By examining the fading Superman, we may uncover a deeper understanding of its environment.

Moreover, it may lead to the establishment of a model for TDEs in AGNs, enhancing future detection efforts. “When a potential TDE is identified in an AGN, it remains uncertain whether it is merely an active galactic nucleus or if a true TDE is occurring, so having such unambiguous evidence is invaluable,” states Vivian Baldassare from Washington State University. “This will greatly aid in revealing future TDEs and understanding various AGN variability sources.”

AI Firm Secures High Court Victory in Copyright Dispute with Photo Agency

An artificial intelligence company based in London has achieved a significant victory in a High Court case that scrutinized the legality of an AI model using extensive copyrighted data without authorization.

Stability AI, led by Oscar-winning Avatar director James Cameron, successfully defended itself against allegations from Getty Images, claiming that it infringed on the international photography agency’s copyright.

This ruling is seen as a setback for copyright holders’ exclusive rights to benefit from their creations. Rebecca Newman, a legal director at Addleshaw Goddard, cautioned that it suggests “the UK derivative copyright system is inadequate to protect creators”.

There was evidence indicating that Getty Images were utilized in training Stability’s model, which enables users to generate images via text prompts. In certain instances, Stability was also found to violate Getty’s trademarks.

Judge Joanna Smith remarked that determining the balance between the interests of the creative industries and AI sectors holds “real social significance.” However, she could only address relatively limited claims as Getty had to withdraw parts of its case during the trial this summer.

Getty Images initiated legal action against Stability AI for violations of its intellectual property rights, claiming the AI company scraped and replicated millions of images with “complete indifference to the content of the training data.”


This ruling comes amid ongoing debates about how the Labour government should legislate on copyright and AI matters, with artists and authors like Elton John, Kate Bush, Dua Lipa, and Kazuo Ishiguro advocating for protections. In contrast, tech firms are seeking broader access to copyrighted material to develop more powerful generative AI systems.

The government is conducting a consultation regarding copyright and AI, stating: “The uncertainty surrounding the copyright framework is hindering the growth of both the AI and creative sectors. This situation must not persist.”

Lawyers at Mishcon de Reya, pursuing this matter, are contemplating introducing a “text and data mining exception” to the UK copyright law, which would enable copyrighted works to be utilized for training AI models unless rights holders opt-out.

Due to a lack of evidence indicating that the training took place in the UK, Getty was compelled to retract its original copyright claim. Nevertheless, the company proceeded with its lawsuit, asserting that Stability continues to use copies of visual assets, which it describes as the “lifeblood” of its business. The lawsuit alleges trademark infringement and “spoofing,” as some generated images bore Getty’s watermark.

Highlighting the complexities of AI copyright litigation, the group essentially argued that Stability’s image generation model, known as Stable Diffusion, constitutes an infringing copy, as its creation would represent copyright infringement if produced in the UK.

The judge determined that “AI models like Stable Diffusion that do not (and never have) stored or reproduced copyrighted works are not ‘infringing copies.'” She declined to adjudicate on the misrepresentation claims but ruled in favor of some of Getty’s trademark infringement claims regarding the watermark.

In a statement, Getty Images remarked: “We are profoundly worried that even well-resourced organizations like Getty Images face considerable challenges in safeguarding creative works due to the absence of transparency requirements. We have invested millions with one provider alone, but we must continue our pursuit elsewhere.”

“We urge governments, including the UK, to establish more robust transparency regulations. This is crucial to avoid expensive legal disputes and ensure creators can uphold their rights.”

Stability AI’s General Counsel, Christian Dowell, stated, “We are pleased with the court’s ruling on the remaining claims in this case. Although Getty’s decision to voluntarily withdraw most of the copyright claims at the trial’s conclusion left the court with only a fraction of the claims, this final decision addresses the core copyright issues. We appreciate the time and effort the court has dedicated to resolving the significant matters in this case.”

Next-Gen Quantum Networks: Paving the Way for a Quantum Internet Prototype

Quantum Internet could provide secure communications globally

Sakumstarke / Alamy

One of the most sophisticated quantum networks constructed to date will enable 18 individuals to communicate securely through the principles of quantum physics. The researchers affirm that this represents a feasible step towards realizing a global quantum internet, although some experts express doubt.

The eagerly awaited quantum internet aims to allow quantum computers to communicate over distances by exchanging light particles, known as photons, that are interconnected through quantum entanglement. Additionally, it will facilitate the linkage of quantum sensor networks, enabling communications impervious to classical computer hacking. However, connecting different segments of the quantum realm is not as straightforward as laying down cables due to the challenges in ensuring seamless interactions between network nodes.

Recently, Chen Shenfeng from Shanghai Jiao Tong University in China demonstrated a method to interconnect two quantum networks. Initially, they established two networks containing 10 nodes each, both sharing quantum entanglement and functioning as smaller iterations of a quantum internet. They then combined one node from each network, resulting in a larger, fully integrated network that enables communication across all pairs of the 18 remaining nodes.

Networking 18 classical computers is a straightforward endeavor involving inexpensive components, but in the quantum sphere, where specific timing is crucial for sharing individual photons among several users, advanced technology and specialized knowledge are required. Even establishing communication between pairs is intricate, yet facilitating communication among any pair of 18 users is unprecedented.

“Our method provides essential capabilities for quantum communication across disparate networks and is pivotal for creating a large-scale quantum internet that enables interactions among all participants,” the researchers stated in their paper, which has not responded to inquiries for comments.

As the researchers clarify, this network integration hinges on a process termed entanglement swapping. Photons can be intertwined by conducting a specific observation known as the Bell measurement. By simultaneously measuring the status of one photon from each of two pairs of entangled photons, the most distant photons in the arrangement become linked. However, attempting to observe their states disrupts the delicate quantum balance and thus depletes the measured photon states.

“This isn’t the initial demonstration of entanglement exchange,” remarks Sidharth Joshi from the University of Bristol, UK. “What they have achieved is a framework that simplifies inter-network exchanges.”

Joshi notes that current quantum communication research is divided between extending the range of information transmission between two devices, occasionally utilizing satellites, and developing protocols and strategies for reliably networking numerous devices over shorter distances. This study pertains to the latter. “Both areas are critically important,” he asserts.

Conversely, Robert Young, a professor at Lancaster University in the UK, commented that while the results showcase a remarkable technical feat demanding expertise and extensive resources, he deems it improbable as a blueprint for future large-scale quantum networks, considering the expense and intricacy involved.

“This is far from practical and not something readily applicable in real-world scenarios,” Young states. “The paper’s claim is that this is the future of quantum network integration, but many formidable challenges remain to be addressed.”

One significant issue is the necessity for quantum repeaters to convey information across extensive distances. As distance increases, photons are frequently lost in fiber optic cables, and measurements can jeopardize the state of a photon, rendering the quantum information unreadable or untransmittable, thereby preventing signal amplification along its route. If quantum repeaters functioned effectively, they could transmit signals over longer distances, yet constructing such devices has been challenging.

“We understand that to build a viable quantum network, some method of quantum repeater is essential,” Young points out, emphasizing that this was absent in the current network demonstration.

‘It Felt Disposable’: Models (Aged 27 and 62) Discuss Botox, Weight Loss, Creativity, and the Impact of AI

I
When we imagine models, they often appear as glamorous individuals who command high fees for their work. However, New York’s Daniel Maleka, 27, and London’s Dee O, 62, reveal that the reality is often a challenging quest for visibility.

The fashion industry is also rapidly evolving. Since O began her modeling career in 1983, the internet and social media have dramatically altered its dynamics. Currently, she’s adapting to trends such as:
AI models appearing in “VOGUE” and
the effects of GLP-1 weight loss drugs.
O and Maleka recently convened to reflect on their careers across different eras.

What’s your story?
D-O: I grew up in Birmingham, from a working-class Irish immigrant family. My boyfriend entered me in the “Face of 1983” contest without telling me. I was about 17 or 18 then. Out of the blue, Look Now magazine called, inviting me as a finalist in Birmingham. Though I didn’t win, the agency still wanted me to represent them, leading me to travel frequently from Birmingham and catch a bus from Victoria at 2 AM after a less than appetizing sandwich.




Composition: Christian Sinibaldi, The Guardian

Daniel Maleka: I was raised in New York by Guyanese-American parents and was inspired to model by watching America’s Next Top Model. Though my family urged me to focus on university first, I explored modeling a little during my teenage years. While studying public health at New York University and running track, a teammate who loved photography helped me take my first photos. As fashion week approached, we reached out to casting directors and designers via Instagram. I eventually signed with WeSpeak, a boutique agency founded by models.

How has your career evolved since then?
D-O:
At 29, I decided to step away from modeling for a regular job. I pursued education, but my daughter, now 27, inspired me to return to modeling, something I initially disliked. Five years later, I found my passion again and signed with Gray Agency, which offers a diverse range of models and continuing opportunities without the stress I once felt.

DM: After five years at WeSpeak, I felt I hadn’t reached my full potential, so I tried a more traditional agency for a year and a half. We clashed often, eventually parting ways. I found my way back to WeSpeak while scouting for a UK agent during a London show with a New York client. Many agencies don’t provide feedback, often leaving me to feel undervalued.

Do: The situation is always murky! It’s challenging to navigate since I desire clarity, yet often, with competition being high, I wonder if I’m overlooked because there are countless others who resemble me.

Dee, how has modeling transformed since your initial days?
Do:
Back then, conversation was minimal. The agent handled all communications, often taking 20% commission. Models just needed to show up with looks. While there’s a surge of writers and stylists in the industry now, not all models fit the same mold. Leveraging platforms like social media is essential for job hunting today.

DM: I’ve cultivated a solid social media presence and experienced waves of viral moments during COVID-19. Much of my career has revolved around online networking and connections.

Does modeling affect how you perceive yourself?
DM:
Some shoots led me to question if others appreciated my looks. For a while, I struggled with my sense of beauty, which is quite a burden.

Do: It’s subtle but impactful. Prioritizing others’ needs and identity over our own can affect mental health significantly over time. When I began in the early 1980s, there was an evident class structure, making me feel like an outsider. There’s also the personal challenge of comparing oneself to other women.




Composition: Christian Sinibaldi, The Guardian

I think models are often seen and not heard, but does this lead to exploitation?
Do:
We witnessed predatory behaviors pre-MeToo in the ’80s. I was fortunate to have a strong voice, which made others wary of me. Yet, I recognized that social invitations might have led to more work, highlighting a power dynamic dominated by men, which made me feel expendable.

DM: I’ve always been progressive. At NYU, I collaborated with organizations on family planning and women’s rights. However, in that previous corporate environment, I often held back my opinions out of fear of agency rejection. Now, I advocate with the
Model Alliance, which fights for model rights. The
Fashion Worker Law passed in New York last year, enhancing protections. Despite this, I still see models being asked to sign contracts that exceed legal requirements, suggesting some continue to exploit the inexperience of newcomers.

Do: Absolutely, naivety, aspirations, and disillusionment.

DM: Joining the Model Alliance Worker Council comes with a warning: your agency could terminate you for being part of it. I had no idea such implications existed.

The Fashion Workers Act: What an impressive step forward!
Is progress occurring elsewhere?
Do:
There’s still a dominance of typical models in runway shows, often standing at 6 feet tall and size 8 or 6. Occasionally, I do see designers like
Ashish Gupta intentionally showcasing diverse models. His recent London Fashion Week show incorporated a troupe of dancers, a creative idea that excites me. It’s also gratifying to see growing awareness about ethical sourcing and environmental concerns in fashion, with greater salary attention for workers. I’m passionate about fashion and proudly represent vintage clothing.

DM: 2020 truly felt like a turning point in Black representation within modeling. After the Black Lives Matter protests, my bookings surged, creating a narrative of inclusivity. Now, however, it appears the trend is regressing, with fewer Black models in the spotlight. Additionally, I often find that stylists aren’t equipped to handle black hair, leading to detrimental outcomes, such as heat damage I experienced.

I’ve heard that models face pressure to remain thin. Have you experienced that?
Do:
I once knew a roommate who was an unhealthy size 12 in the UK (8 in the US). She lived on apples, battled rotting teeth, and suffered from bulimia, all in pursuit of agency approval for the desired height and size. Ultimately, she became sick and had to return home, a memory I’ll never forget.

DM: This issue has long affected model standards, and while I maintain a fit physique, I’ve gradually come to realize the pressures of being thinner. Initially, I was more muscular due to my athletics, but feedback like, “You need to change your dimensions,” during meetings hit me hard emotionally.

Do: Such standards have a profound impact on your mental state. Yet, we’re witnessing an emergence of diverse body shapes and sizes. Although it appears better than before, curvy models still face stereotypes, often expected to have hourglass figures.

With innovations like Botox and weight loss medications, have you noticed changes in the industry?
DM:
My peers who model plus sizes have expressed that these developments affect their runway bookings.


Do: On one job, they even taped my face to alter my skin. If my face isn’t good enough, why book someone older? These thoughts persist. I find myself torn about it; I have never undergone Botox or surgery, yet contemplate it. Models of my age at that shoot often shared similar feelings, emphasizing the contradictions we navigate.

Are you concerned about your images being used for deepfakes or AI training?
DM:
The Model Alliance included a clause in their legislation requiring written consent from models for such uses. There’s apprehension about the risk of my image being misused, especially with the vulnerability posed by sharing on platforms like Instagram.

Would you recommend modeling as a career?
DM:
Yes, it offers fulfillment and is often playful and fun, allowing you to embrace your inner child. However, if I had children, I’d prefer they start their modeling journey later, not at 15 or 16.

Do: I mirrored my parents’ approach with my daughter, insisting she finish college first. Nevertheless, her determination prevailed. I’m grateful for her resolve, especially as we now collaborate in the industry.

DM: I urge pursuing interests outside of modeling. After gaining recognition through TikTok, I perceived it as my sole identity for a while, which left me feeling disoriented.

Do: Traveling worldwide has been invaluable; even those experiences justify the journey. However, it’s critical to remember that success can vanish overnight.

Norwegian Wealth Fund Rejects Elon Musk’s $1 Trillion Compensation Package for Tesla

Norway’s sovereign wealth fund has declared its intention to oppose Tesla’s proposed $1 trillion (£765 billion) compensation package for Chief Executive Elon Musk.

The largest national wealth fund stated that it acknowledges “the remarkable value created under Mr. Musk’s visionary leadership” but will vote against his performance-based award.

“In line with our stance on executive compensation, we are worried about the total remuneration, dilution, and the absence of risk mitigation for essential personnel.” “We remain eager to engage in constructive discussions with Tesla on this and other matters.”

The alert from Norges Bank, Tesla’s seventh-largest single shareholder with $17 billion in stock, arrived just two days prior to Tesla’s annual shareholder meeting.

On Thursday, shareholders are expected to vote on an extraordinary incentive proposal that could propel Elon Musk to become the world’s first trillionaire.

If Musk escalates Tesla’s valuation from approximately $1 trillion to $8.5 trillion over the next decade, he would be granted new shares, and his ownership stake would increase from nearly 16% to over 25%.

This would boost the wealth of the world’s richest man to over $2 trillion.

Tesla Chairman Robin Denholm emphasized that this vote is crucial to retaining Musk, 54, as the company’s CEO, stating in a letter to shareholders that the company might lose “significant value” should he depart.

Last year, the Norwegian Oil Fund opposed Musk’s $56 billion compensation plan, which was the largest in U.S. corporate history at the time. Although it was approved by shareholders in June, a Delaware court later rejected it a second time in December.

Nikolai Tangen, the chief executive of the Norwegian fund, had invited Musk and other CEOs to a dinner in Oslo last year, but Musk declined after the fund voted against the $56 billion compensation package.

Text exchanges between Tangen and Musk were disclosed in a Freedom of Information request by Norwegian business magazine DN. The newspaper reported that Musk texted Tangen in October last year: “It’s not often that I ask you for a favor and you say no. Then you shouldn’t ask me for a favor until I do something more than make up for it. A friend is a friend.”

Shareholders are split on the proposed deal, with two significant shareholder advisory firms, Glass Lewis and ISS, both advising investors to reject the $1 trillion package.

Several major pension funds are also against the pay structure, including the American Federation of Teachers and the California Public Employees’ Retirement System, the largest public system in the nation.

Musk, being Tesla’s largest single shareholder, also has a vote on the proposal.

Last month, Tesla’s president stated on the social media platform X, which he acquired in 2022, “Tesla is worth more than all the other car companies combined. Which CEO would want to run Tesla? It wouldn’t be me.”

Tesla was approached for comment.

Scientists Discover Largest Black Hole Flare Ever Recorded, Emitting 10 Trillion Solar Rays

A supermassive black hole has violently consumed a massive star, resulting in a cosmic explosion that shone as brightly as 10 trillion suns, according to a recent study.

This event, referred to as a black hole flare, is believed to be the largest and most remote ever detected.

“This is genuinely a one-in-a-million occurrence,” stated Matthew Graham, a research professor of astronomy at the California Institute of Technology and the lead author of the study published Tuesday in Nature Astronomy.

Graham indicated that based on the explosion’s intensity and duration, a black hole flare is likely the explanation, but further studies will be necessary to validate this conclusion.

While it is common for black holes to devour nearby stars, gas, dust, and other materials, such significant flare events are exceptionally rare, according to Graham.

“This enormous flare is far more energetic than anything we’ve encountered previously,” he remarked, noting that the explosion’s peak luminosity was 30 times that of any black hole flare documented so far.

Its extreme intensity is partly due to the massive size of the celestial objects involved. The star that came too close to the black hole is estimated to possess at least 30 times the mass of the Sun, while the supermassive black hole and its surrounding matter disk are estimated to be 500 million times more massive than the Sun.

Graham mentioned that these powerful explosions have persisted for more than seven years and are likely still ongoing.

The flare was initially detected in 2018 during a comprehensive sky survey using three ground-based telescopes. At the time, it was identified as a “particularly bright object,” but follow-up observations months later yielded little valuable data.

Consequently, black hole flares were mostly overlooked until 2023, when Graham and his team opted to revisit some intriguing findings from their earlier research. Astronomers have since managed to roughly ascertain the distance to this exceptionally bright object, and the results were astonishing.

“Suddenly, I thought, ‘Wow, this is actually quite far away,'” Graham explained. “And if it’s this far away and this bright, how much energy is it emitting? This is both unusual and intriguing.”

While the exact circumstances of the star’s demise remain unclear, Graham hypothesized that a cosmic collision might have nudged the star from its typical orbit around the black hole, leading to a close encounter.

This finding enhances our understanding of black hole behavior and evolution.

“Our perspective on supermassive black holes and their environments has dramatically transformed over the past five to ten years,” Graham stated. “We once pictured most galaxies in the universe with a supermassive black hole at the center, idly rumbling away. We now recognize it as a much more dynamic setting, and we are just beginning to explore its complexities.”

He noted that while the flares are gradually diminishing over time, they will remain detectable with ground-based telescopes for several more years.

UK Criminalizes Pornographic Content Involving Strangulation

The act of choking in pornography, often referred to as ‘choking,’ will be criminalized, with legal obligations imposed on technology platforms to prevent users in the UK from accessing such content.

Proposed amendments to the Crime and Policing Bill introduced in Parliament on Monday will make it illegal to possess or distribute pornography that features choking.

An additional amendment aims to extend the timeframe for victims of intimate image abuse to come forward, increasing the prosecution limit from six months to three years.

The government stated that these changes would eliminate unnecessary obstacles for victims reporting crimes, thus “enhancing access to justice for those in need.”

The choking ban follows a government review that suggested pornography was fostering the normalization of strangulation as a “sexual norm.”

The Independent Pornography Review, initiated by former chancellor Rishi Sunak and conducted by Baroness Gabby Bertin, published its findings in February, recommending a prohibition on pornography featuring strangulation.

Despite the common belief that strangulation can be performed safely, studies indicate that it poses significant risks. While there may be no visible injuries, oxygen deprivation—even for brief moments—can cause detrimental changes to the brain’s delicate structures.

Research has revealed specific alterations in the brains of women who have been subjected to choking during sexual activities, showing indicators of brain damage; Hemisphere disruption associated with depression and anxiety.

Given these dangers, non-fatal strangulation and non-fatal asphyxiation were categorized as criminal offenses in the Domestic Abuse Act 2021, amid concerns that offenders often escape punishment due to the absence of visible injuries.

The new amendments will mandate platforms to take proactive measures to block users’ access to illegal content involving strangulation and suffocation.

Choking-related offenses will be prioritized, imposing a legal responsibility on pornographic sites and tech platforms to ensure UK users cannot view such material.

The Ministry of Justice indicated that this might involve the use of automated systems for the detection and removal of images, moderation tools, or stricter content policies to hinder the spread of abusive material.

Failure to comply could result in fines of up to £18 million imposed by Ofcom.

Barney Ryan, CEO of the Strangulation Research Institute, expressed support for the ban, stating, “While consenting adults should have the freedom to safely explore their sexuality, we must recognize the severe risks posed by unregulated online content, particularly to children and young people.

“Strangulation represents a severe form of violence, often employed in domestic violence for control, silence, or to induce fear. Its portrayal in pornography, especially without context, can impart confusing and harmful messages to youth regarding what is normal and acceptable in intimate relationships. Our research confirms that there is no safe way to strangle.”

Alex Davis-Jones, Minister for Victims and Violence Against Women and Girls, emphasized that online misogyny “has devastating real-world impacts on all of us.” Daily, women and girls have their lives disrupted by cowards who abuse and exploit them from behind screens.

“This government will not remain passive while women face online violations and become victims of normalized and violent pornography.

“We are delivering a strong message that dangerous and sexist behavior will not be tolerated.”

This initiative comes on the heels of a government-commissioned inquiry in 2020 that revealed “significant evidence.” The link between pornography use and harmful sexual attitudes and behaviors toward women.

Additionally, a study conducted that year found that many children had encountered violent or offensive pornography, which left them feeling upset or anxious; some even mimicked the behaviors observed online. Children who engaged with pornography were three to six times more likely to participate in “potentially risky behavior” concerning consent, according to a study by the British Board of Film Classification. .

Apple Watch SE 3 Review: An Excellent Value Smartwatch for iPhone Users

Apple’s affordable Watch SE has received almost all the enhancements of the superb mid-range Series 11, yet it is priced around 40% less, making it an excellent value smartwatch for iPhone users.


The new Watch SE 3 begins at £219 (€269/$249/AU$399), positioning it as one of the most affordable fully-featured smartwatches compatible with iPhones, significantly cheaper than the £369 Series 11 and the premium Apple Watch Ultra 3 at £749.

The SE series has seen periodic updates, and while it has offered good value, it has missed key features that enhance Apple’s other watches. The most significant improvement in the Watch SE 3 is the always-on display, aligning it with the Series line and allowing you to view the time and notifications at a glance, eliminating the need to raise your wrist to activate the screen.

The SE 3 follows the older Apple Watch design seen in the 2020 Series 6, featuring a smaller display and thicker bezels, with options for 40mm or 44mm case sizes compared to the latest series watches. While it doesn’t shine as bright as the pricier models in direct sunlight, it remains sharp and appealing.

Equipped with the same S10 chip as the Series 11 and Ultra 3, the SE 3 provides a similar responsive experience. It also includes excellent touch-free gestures like double-tap and wrist flick to effortlessly dismiss notifications, timers, and alarms.

Furthermore, the watch supports all the standard Apple Watch functionalities found in watchOS 26, such as contactless payments via Apple Pay, detailed notifications, music playback controls, third-party apps, and various watch face options.




The SE 3 runs all the same applications and services as its pricier counterpart. Photo: Samuel Gibbs/The Guardian

The SE 3’s battery life falls slightly short of that of the Series 11, lasting approximately a day and a half under typical usage, which includes one night of sleep tracking. Many users may need to recharge it every other day, especially if they monitor workouts. The SE 3 allows for up to 7 hours of GPS and heart rate tracking during running, which is sufficient for a marathon. Charging fully with the magnetic charger takes about 1 hour, reaching 70% in 30 minutes.

Specifications

  • Case size: 40mm or 44mm

  • Case thickness: 10.7mm

  • Weight: Approximately 26g or 33g

  • Processor: S10

  • Storage: 64GB

  • Operating system: watchOS 26

  • Water resistance: 50 meters (5ATM)

  • Sensors: HR (2nd generation), skin temperature, NFC, GNSS, compass, altimeter

  • Connectivity: Bluetooth 5.3, Wi-Fi 4, NFC, optional 5G

Health and Workout Tracking

A significant drawback of the SE 3 is the absence of the electrical sensor on the watch’s back, which enables ECG monitoring on the Series and Ultra models. It also lacks blood oxygen monitoring and blood pressure alerts, but it does feature an accurate optical heart rate sensor with most related capabilities, such as high and low heart rate notifications.

The SE 3 includes a skin temperature sensor. Its Vital app provides sleep tracking, along with retrospective ovulation estimates for cycle tracking applications. This smartwatch excels in tracking popular workouts using GPS, including walking, running, and cycling, among others.

Additionally, the watch supports offline music playback via Bluetooth headphones from subscription services like Spotify and offers offline access to Apple Maps in case you lose your phone.

Sustainability

According to Apple, the battery can last more than 1,000 full charge cycles while retaining at least 80% of its original capacity and is replaceable at a cost of £95. Repair costs range from £195 to £229, depending on the model.

The watch contains over 40% recycled materials, including aluminum, cobalt, copper, glass, gold, lithium, rare earth elements, steel, tin, titanium, and tungsten. Apple also provides device trade-ins and free recycling options, while its report details the environmental impact of its products.

Price

The Apple Watch SE 3 starts at £219 (€269/$249/AU$399) for the 40mm variant and £249 (€299/$279/AU$449) for the 44mm variant.

For reference, the Apple Watch Series 11 is priced at £369, and the Apple Watch Ultra 3 retails for £749.

Verdict

The Apple Watch SE 3 stands out as the best value in Apple’s smartwatch lineup this year, delivering nearly all of the remarkable features found in the Series 11 at a much lower price point.

With its new always-on display, S10 chip, and watchOS 26, the SE 3 is equally user-friendly for daily tasks. The main feature missing is the EKG capability, but this may not be a concern for those who don’t require it. The 40mm version’s battery life of 1.5 days is decent, while the larger 44mm model should provide slightly longer use.

Limited color selections can be easily improved with brighter bands, but the older design featuring a smaller display, larger bezels, and thicker body is acceptable considering the pricing.

Pros: Excellent value Apple Watch, always-on display, Apple Pay, double-tap and wrist flick gestures, solid health and fitness tracking, long-lasting software support, environmentally friendly materials, and 50 meters of water resistance.

Cons: Lacks EKG, no blood oxygen monitoring, no blood pressure alerts, older design, compatible only with iPhone, no third-party watch faces, and display can be dim in bright sunlight.

This intermediate spiral galaxy was discovered on April 12, 1789, by the German-British astronomer William Herschel.

Also known as UGC 7096, NGC 4102 features an active galactic nucleus.

“Active galactic nuclei are luminous centers within galaxies, powered by supermassive black holes with masses millions to billions of times greater than that of the Sun,” stated Hubble astronomers.

“When these black holes attract surrounding gas, the intense gravitational forces cause the gas to heat up and emit light across various wavelengths, from X-rays to radio,” they added.

“NGC 4102 stands as a prime candidate for examining the interaction between active galactic nuclei and their host galaxies,” noted the researchers.

“These active galactic nuclei range from very powerful variants that consume significant amounts of matter and produce jets of charged particles to more subdued types that gently draw in gas and emit less intense light.”

“NGC 4102 is likely categorized among the latter; it falls within the Compton-thickness classification, indicating a dense gas environment surrounding its nucleus, and is identified as a low-ionization nuclear emission line region (LINER).”

“LINER galaxies are recognized by emission lines from weakly ionized elements and may be sustained by supermassive black holes gradually accumulating gas from their vicinity.”

Previous imaging of NGC 4102, derived from observations with Hubble’s Wide Field Planetary Camera 2 (WFPC2), was released in 2014.

“The latest imaging offers an enhanced view of the galaxy, utilizing data from Hubble’s Wide Field Camera 3 (WFC3), which replaced WFPC2 in 2009, providing improved resolution and a larger field of view,” according to the researchers.

“These new observations are part of a program that integrates visible-light imagery from Hubble with X-ray data from the Chandra X-ray Observatory, aimed at exploring NGC 4102 and its relationship with active galactic nuclei.”

Ancient Crimean Neanderthal from 45,000 Years Ago Uncovers Extensive Eurasian Connections

Recent discoveries by archaeologists in Ukraine’s Crimean Peninsula, home to significant Middle to Late Paleolithic sites like Starosele, include a 5-centimeter-long bone fragment from a Neanderthal man, dating between 46,000 and 44,000 years ago. Genetic analysis shows this individual to be closely related to Altai Neanderthals through mitochondrial DNA, indicating that Neanderthal populations traveled great distances across Eurasia. Under favorable climatic conditions, these migrations likely involved the spread of the Micocchia stone tool industry, highlighting cultural continuity and regional adaptability during the Late Pleistocene.

Crimea is rich in well-preserved layered Paleolithic sites, many reflecting the biocultural and human occupation transition that occurred approximately 47,000 to 42,000 years ago.

According to earlier radiocarbon dating studies, the peninsula has been recognized as a refuge for late Neanderthals who survived just before their extinction.

Starosele, a rock shelter located in a steep valley, features four distinct cultural layers and has been researched since 1952.

“The archaeological layers of this site are rich in cultural artifacts,” stated Emily Piggott, a PhD student at the University of Vienna, along with her colleagues.

“Levels 1, 2, and 4 are linked to stone tools from the Crimean Mikokian stone tool industry, associated with Neanderthals.”

This study aimed to identify potential human remains from the thousands of fragmented bones excavated from the Starosele site.

From the 150 bone fragments analyzed, 97.3% contained sufficient collagen for taxonomic identification.

Approximately 93% of the remains belonged to horses and deer, with fewer found from mammoths and wolves, indicating that Paleolithic humans in Crimea heavily relied on horse hunting.

Notably, one bone fragment, measuring 49.8 mm in length and 18.8 mm in width, was classified as hominin.

Radiocarbon dating indicated an age range of 46,000 to 45,000 years, coinciding with the transitional period before the extinction of Neanderthals and the emergence of Homo sapiens in Western Europe.

“Particularly the remains of humans before Starosele are from a much later era of Homo sapiens,” Piggott remarked.

“Upon receiving the radiocarbon results, we realized we had uncovered a true Paleolithic hominin.”

“Neanderthals went extinct across Eurasia, replaced by Homo sapiens, yet genetic information about these earlier human populations is scarce.”

Researchers then sequenced the mitochondrial genome from this bone, confirming the individual was part of the Neanderthal lineage.

The mitogenome of this individual aligns with other Neanderthal mitogenomes previously documented in the Altai region of Siberia.

“Surprisingly, this individual shared the closest genetic ties with Neanderthals from Altai, over 3,000 kilometers to the east, as well as with Neanderthals that once roamed areas of Europe such as Croatia,” highlighted the researchers.

“This finding reaffirms previous studies suggesting that Neanderthals migrated extensively across Eurasia, traversing from central Europe to central Eurasia during the late Pleistocene.”

“This research highlights Crimea as a crucial junction in the Neanderthal migration routes.”

The findings of this study will be published in Proceedings of the National Academy of Sciences.

Revolutionary Paint-Like Coating Harvests Water from Air

Researchers at the University of Sydney, in collaboration with Dewpoint Innovations, have engineered a porous polymer coating that can reflect as much as 97% of sunlight, dissipate heat into the atmosphere, and maintain surface temperatures up to 6 degrees cooler than the ambient air—even in direct sunlight. This mechanism fosters ideal conditions for atmospheric water vapor to transform into water droplets on these cooler surfaces, much like the condensation seen on a bathroom mirror.

Professor Chiara Neto from the University of Sydney stated: “This innovation not only advances cool roof coating technology, but also paves the way for sustainable, low-cost, decentralized freshwater sources—an essential requirement given the challenges of climate change and rising water scarcity.”

A six-month field study conducted on the roof of the Sydney Nanoscience Hub demonstrated that dew was collected for 32% of the year, enabling a sustainable and reliable water source even during dry spells.

Under optimal conditions, this coating can yield up to 390 mL of water per square meter daily—sufficient for a 12-square-meter home, meeting one person’s daily hydration needs.

This research illustrates the integration of passive cooling techniques and atmospheric moisture collection into scalable paint-like solutions.

The extensive collection area suggests that this coating could have diverse applications in various industries, including water supply for livestock, horticulture for premium crops, cooling through spraying, and hydrogen production.

Contrary to conventional white paints, the porous coatings utilizing polyvinylidene fluoride-co-hexafluoropropene (PVDF-HFP) do not depend on UV-reflective pigments like titanium dioxide.

Dr. Ming Chiu, Chief Technology Officer of Dewpoint Innovations, remarked, “Our design achieves superior reflectiveness through an internal porous structure, ensuring longevity without the environmental downsides of pigment-based coatings.”

“By eliminating UV-absorbing materials, we have surmounted traditional limitations of solar reflectance while avoiding glare from diffuse reflection.”

“This equilibrium between performance and visual comfort enhances its ease of integration and appeal for real-world applications.”

Throughout six months of outdoor examination, researchers documented minute-by-minute data on cooling and water collection, confirming solid performance that remained stable under the harsh Australian sun—unlike similar technologies that often degrade quickly.

In addition to water harvesting, these coatings could help mitigate urban heat islands, lower energy needs for air conditioning, and provide climate-resilient water sources for regions facing heightened heat and water stress.

“This research also challenges the notion that dew collection is confined to humid environments,” noted Professor Neto.

“While humid conditions are optimal, condensation can also occur in arid and semi-arid areas where humidity increases during the night.”

“It isn’t a substitute for rainfall; rather, it serves as a water source when other supplies are scarce.”

The team’s work was published in the October 30th issue of Advanced Functional Materials.

Rhinos Roamed the High Arctic 23 Million Years Ago

Paleontologists have identified a new early Miocene species of rhinoceros from the genus Epiaceratherium, based on fossilized remains uncovered in the Canadian Highlands Arctic.

This new rhinoceros existed in present-day Canada around 23 million years ago during the early Miocene epoch.

Named Epiaceratherium ijirik, it is most closely related to other rhinoceros species that thrived in Europe millions of years ago.

“Currently, there are only five species of rhinos found in Africa and Asia, but they were once widespread in Europe and North America, with over 50 species documented in the fossil record,” stated Dr. Daniel Fraser, a researcher from the Canadian Museum of Nature, Carleton University, and the Smithsonian’s National Museum of Natural History.

“The inclusion of this Arctic species enriches our understanding of the evolutionary history of rhinoceroses.”

Epiaceratherium ijirik was relatively small and slender, comparable in size to a modern Indian rhinoceros, but notably lacked a horn.

The fossilized remains were excavated from the sediments of a fossil-abundant lake in Horton Crater on Devon Island, Nunavut.

“What’s impressive about this Arctic rhinoceros is the excellent condition of the fossilized bones,” remarked Dr. Marisa Gilbert, also from the Canadian Museum of Nature.

“They are three-dimensionally preserved and only partially mineralized.”

“Approximately 75 percent of the skeleton has been recovered, which is remarkably complete for a fossil.”

By analyzing the occurrences of 57 other now-extinct rhino species, researchers traced the family tree of Epiaceratherium ijirik.

The findings were derived from visits to museum collections, reviews of scientific literature, and database analyses.

The researchers were also able to geographically categorize each rhino species across five continental regions.

This exhaustive process employed mathematical modeling techniques to gauge dispersal rates among different continents within the Rhinocerotidae family, with scoring based on their locations.

The analysis sheds light on how rhinoceroses utilized the North Atlantic land bridge for migration between North America and Europe (via Greenland) over millions of years.

Previous studies indicated that the land bridge may have served solely as a migration route until about 56 million years ago.

However, the new analysis implies that Epiaceratherium ijirik and its relatives suggest that these migrations from Europe to North America could have occurred much more recently, potentially as late as the Miocene.

“Discovering and describing new species is always thrilling and enlightening,” noted Dr. Fraser.

“But there is more to be gleaned from this identification: Epiaceratherium ijirik reveals that the North Atlantic played a more significant role in rhinoceros evolution than previously acknowledged.”

“Overall, this study reaffirms that the Arctic continues to unveil new insights and discoveries, enhancing our understanding of mammalian diversification across epochs.”

Results of this research are published in the journal Nature Ecology and Evolution.
