Hollow Knight: Silksong Launch Causes Crash in Online Game Store | Games News

The enigmatic three-person game development team based in Adelaide has stirred up a storm on the global online gaming scene.

On Friday, major platforms like Steam, Nintendo’s eShop, PlayStation Store, and Microsoft Store all experienced crashes as they struggled to keep up with the demand for Hollow Knight: Silksong, the eagerly awaited sequel to the acclaimed 2017 indie sensation, Hollow Knight.

The game’s launch resulted in widespread outages, with thousands of players reporting difficulties in purchasing the game during the initial hours of its release. Many faced persistent error messages for almost three hours post-launch, preventing them from completing their transactions.


The spike in demand was evident on down detectors across troubleshooting platforms, which recorded a surge to 3,750 users immediately after the game’s launch, slowly diminishing thereafter.

Social media erupted with complaints about error codes and shared screenshots as frustrated gamers expressed their disappointment over the absence of pre-order options. Some labeled the situation as “absurd,” while others criticized the lack of measures to prevent such congestion.

Another digital retailer, Humble Bundle, indicated that the game was momentarily unavailable due to high traffic, although this notification was later removed once the situation stabilized.

Regardless of these technical challenges, Steam noted over 100,000 active players within just 30 minutes of launch, implying that many managed to secure their copies.

Hollow Knight was crafted by Ari Gibson, William Pellen, and Jack Vine, along with music from Christopher Larkin, representing the Adelaide-based indie studio, Team Cherry. Set in a vividly imagined realm of insect warriors, the game has garnered a passionate following since its debut in 2017, selling over 15 million copies globally.

The New York Times recently hailed the original Hollow Knight as a “Modern Metroidvania Classic,” praising its “engaging and detailed hand-drawn animations, challenging boss encounters, and twists with secret pathways.”

The original has achieved cult status, largely through word-of-mouth recommendations. Anticipation for a sequel focusing on Hornet, the sword-wielding princess who served as a supporting character in the first game, has grown, as highlighted by a recent New York Times report that discussed at least seven new game developments avoiding past conflicts and employing gaming demons in baby steps and tactical roles in Walking Sims.

The development of the game was financed independently, though a South Australian film company celebrated Team Cherry’s global success on Friday, stating, “This small team of combat developers in Adelaide showcases world-leading talent and the creative excellence that emerges from South Australia.”

In a recent Bloomberg interview, Gibson mentioned that the seven-year development timeline of Silksong is entirely attributed to the team’s choice of project.

“We’re a small team, and it takes us considerable time to create the game,” he explained. “There wasn’t any significant controversy surrounding it.”

In a previous discussion with ABC, Pellen attributed the original Hollow Knight’s lasting appeal to its blend of classic inspiration and modern aesthetics.

“What was gratifying about Hollow Knight was that we crafted something according to our tastes, leading to a slightly unique product,” Pellen stated in the ABC interview. “We hope Silksong can achieve something similar.”

White House Funding Cuts Endanger AI Weather Forecasting Institute

Funding for a $20 million artificial intelligence lab aimed at enhancing weather forecasts has been halted by the Trump administration. This decision threatens both the pipeline of scientists and the nation’s capability to evaluate the effects of hurricanes and other weather-related disasters.

According to Amy McGovern, the director of the Institute for AI2ES (AI Institute for Heather and Weather, Climate, and Coastal Oceanography), the National Science Foundation (NSF) informed the institute last month that it would not extend its five-year grant.

McGovern, who serves as a professor of meteorology and computer science at the University of Oklahoma, stated:

She emphasized that, without private funding, the institute may have to close its doors next year.

AI2ES collaborates with various universities to integrate AI into weather forecasting while evaluating its reliability.

This move to shut down AI2ES occurs as the Trump administration is heavily investing in AI and accelerating the establishment of data centers. The administration’s own AI plan advocates for the development of AI systems and programs aimed at fostering AI vocational training programs and specialized AI labs across various scientific fields.

In July, the administration unveiled an ambitious plan to achieve “global dominance” in artificial intelligence, emphasizing both innovation and its implementation—key areas of focus for AI2ES.

Alan Gerald, the former director of the National Intensive Storm Institute at the National Oceanic and Atmospheric Administration, described the cut as “dissonance” in light of this trend toward advancing technology.

The White House has not responded to requests for comments regarding this matter.

The institute was established in 2020 under the previous Trump administration as part of the NSF’s AI research labs, having received around $20 million in funding over the past five years. An NSF spokesperson, Michael England, stated that the agency holds the AI Institute’s groundbreaking work in high regard.

The National Science Foundation is fully committed to advancing artificial intelligence research through the National AI Research Institute Program, a pivotal aspect of the administration’s strategy to reinforce the US’s leadership in transformative AI.

NSF and its collaborating partners have provided funding for a network of 29 AI institutes. This year, AI2ES was one of five labs updated through the NSF, with three labs having received updates, while the status of the fourth remains pending, according to McGovern.

The Trump administration has proposed a 55% budget cut for the NSF; however, Congress has not yet ratified the budget. Senate and House appropriations have diverged from the Trump administration’s proposals, suggesting smaller cuts to scientific institutions like the NSF.

“We were an AI lab, so we believed we were secure, given our alignment with the president’s priorities,” McGovern noted.

The Trump administration’s AI plan aims for NSF and other organizations to expose K-12 students to AI careers, develop industry-driven training programs to generate AI jobs, and bolster workforce initiatives to enhance the nation’s AI talent pool.

“They desire a more robust AI-trained workforce. We were doing a significant amount of work,” McGovern emphasized.

She expressed concern that private AI firms are “poaching talent constantly,” as the institute funds around 70 positions each year at various universities, creating a talent pipeline. Among the institute’s achievements are over 130 academic publications and the development of AI tools used by the government today.

The center aided in the creation of AI tools that predict weather events potentially endangering sea turtles near Corpus Christi, Texas, making these animals susceptible to hazards onboard vessels.

Additionally, the institute developed an application enabling forecasters to “see” within hurricanes, even without a polar orbit satellite equipped with a microwave sensor capable of penetrating storm clouds. This application utilizes data from Earth-measuring satellites that cannot penetrate clouds and simulates the internal structure of a hurricane.

The center is also investigating how forecasters evaluate the reliability of AI tools developed by private companies, including Google.

“We have social scientists who engage with end-users to comprehend their trust in AI, their reservations, and what improvements are necessary,” remarked McGovern.

According to Gerald, if the center were to shut down, it wouldn’t adversely affect current weather forecasting but could limit innovation and place the nation at a disadvantage.

“Many other countries are heavily investing in AI-related weather research, like China. They risk falling behind many nations committed to enhancing weather forecasting,” Gerald concluded.

LCD Lenses: Enhancing Your Divine Glasses Experience

The inaugural prototype of LCD BeforeCal

Lin et al./APS 2025

Glasses featuring LCD lenses offer a convenient way to switch between correcting for near and distant vision.

Bifocal glasses have a history stretching back to the 18th century, with designs that haven’t changed significantly over time. Typically, the lower section of the lens is shaped for nearby viewing, while the upper section is designed for distance, requiring wearers to shift their gaze frequently. A team led by Yi-Hsin Lin at National Yang Ming Chiao Tung University and Chuo Tung University in Taiwan has developed a pair of glasses that can toggle between two modes at the press of a button.

Rather than traditional glass lenses, these new lenses utilize a thin layer of liquid crystals controlled by an electric field, which alters the arrangement of the molecules to bend light in different ways depending on their function.

The concept of adjustable glasses using this principle, which produces the necessary electric field through thin electrodes embedded in the frame, is nearly 50 years old. However, advancements have been slow due to various technical obstacles. Lin and her colleagues have addressed some of these challenges, creating a wearable prototype.

The current iteration of these glasses offers a limited power range, boasting a functional viewing area of about 10 millimeters (3 to 4 times larger than traditional bifocals) and a switch time of approximately 5 seconds upon pressing the button on the frame. Nonetheless, Lin’s team has successfully identified the physical principles enabling these glasses to function effectively, and they are optimistic about future improvements in areas such as reducing switching times through electronic optimization. “Almost everyone will need prescription eyewear at some point, so the market potential is enormous,” claims team member Victor Reshetnyak from Taras Shevchenko National University in Kiev, Ukraine.

Viola Kanevsky, an optometrist in New York, notes that those most likely to benefit from these adaptive glasses are in technical fields where small objects may occupy significant visual focus or in professions requiring a broad perspective—such as architects evaluating long, straight lines or stockbrokers monitoring multiple large screens both near and far without needing to constantly adjust their heads.

However, these new prototypes are still far from being ready for clinical application due to the limited operational areas of the lenses, according to Mark Rosenfield from SUNY Optometry University in New York. The inclusion of electronic components also raises both the cost and complexity of manufacturing LCD glasses. Similarly, Joshua Silver from Oxford University highlighted that in 2004, he and his colleagues developed alternative self-adjustable eyeglass designs utilizing liquids.

Single Doses of LSD Appear to Alleviate Anxiety

SEI 264621700

Can psychedelics be effective against common anxiety disorders?

Science Photo Library/Alamy

Research indicates that a single dose of LSD may alleviate anxiety without causing lasting side effects.

“We are conducting the first modern examination of LSD and its effects on common anxiety disorders,” says Dan Carlin from Mindmed in New York.

This disorder is marked by persistent worry about various issues, including work and relationships. Standard treatments often involve mood-enhancing medications and therapies, like selective serotonin reuptake inhibitors (SSRIs) and other antidepressants.

However, approximately half of patients do not respond to these treatments. “SSRIs are ineffective for many; they can produce side effects, such as emotional numbness, and must be taken daily to have any effect,” Carlin explains.

Previous studies propose that LSD might serve as an alternative treatment. Psychedelics are frequently used for their mind-altering hallucinations in recreational contexts. Carlin believes they may operate by enhancing serotonin levels in the brain, which improve mood, and may also encourage the brain’s capacity for rewiring and developing new thought patterns.

Nonetheless, so far, trials directly comparing LSD with a placebo have not specifically evaluated its effects on generalized anxiety disorder.

To address this issue, Carlin and his team recruited 198 adults with this condition. Participants gradually reduced their current anxiety medications, while those receiving psychotherapy continued their sessions.

In a standard clinical assessment, participants rated the intensity of 14 symptoms, including worry, tension, and difficulty focusing, on a scale from 0-4.

The team then randomly assigned participants into five groups—those receiving LSD (in doses of 25, 50, 100, or 200 micrograms) or placebo tablets. The following day, those who received doses of 100 and 200 micrograms reported greater symptom relief compared to other groups, according to Karlin.

One month later, participants who took the 100 and 200 microgram doses noted an average anxiety reduction of 21 and 19 points, respectively, with improvements sustained until the study’s conclusion three months later. Approximately 46% of these individuals were in remission.

In contrast, those receiving placebo and the lower doses experienced a 14-17 point reduction in anxiety over the same period, with about 20% achieving remission. This indicates that the lower doses did not yield significant benefits beyond the placebo effect.

The enhancements seen with the higher doses are significantly greater than those produced by the placebo, states Sunjeev Kamboj from University College London. “This marks a clinically meaningful improvement in terms of distress and disability,” he notes.

The progress observed in the placebo group is a common occurrence in anxiety studies, likely influenced by factors such as participants’ enthusiasm and attention during the trial, Kamboj adds.

The team noted that they could accurately ascertain whether most participants received LSD or placebo. Psychedelics typically produce hallucinations, which can affect many individuals. Across all groups, participants experienced nausea and headaches about 12 hours post-treatment.

At lower LSD doses, those on placebo reported hallucinations significantly less frequently than at higher psychedelics doses. This complicates the assessment of whether the benefits observed are due to individual expectations based on perceived effects or the direct influence of the drug on the brain, Kamboj explains.

Despite these caveats, the study offers compelling evidence that LSD could be a viable anxiety treatment, he states. “It’s a promising finding, indicating it can quickly alleviate symptoms. This is highly relevant for patients.”

The results have led the US Food and Drug Administration to classify MindMed’s LSD formulations as a breakthrough therapy, expediting the drug development process. Karlin mentions that the team has conducted thorough follow-up trials for over three months, with anticipated results forthcoming in the next few years.

Discovering a New Type of Black Hole: Insights from Mirror Technology and Insect-Inspired AI

Gravitational waves result from colliding black holes

Victor de Schwanberg/Science Photography Library

Researching the universe can be enhanced by AI created by Google DeepMind. With an algorithm capable of diminishing unwanted noise by as much as 100 times, the Gravitational Wave Observatory (LIGO), equipped with laser interferometers, can identify specific black hole types that are affecting our separation.

LIGO aims to detect gravitational waves generated when entities like black holes spiral and collide. These waves traverse the universe at light speed, yet the spacetime fluctuations are minimal—10,000 times smaller than an atomic nucleus. Since its initial detection a decade ago, LIGO has recorded signals from nearly 100 black hole collisions.

The experiment comprises two U.S. observatories, each with two perpendicular arms measuring 4 km. A laser is directed down each arm and bounced off precise mirrors, where an interferometer compares the beams. As gravitational waves pass through, the lengths of the arms fluctuate slightly, and these changes are meticulously documented to help visualize the signals’ origins.

However, achieving such precision is challenging, as even distant ocean waves or clouds can interfere with measurements. This noise can overwhelm the signal, rendering some observations unfeasible. To counterbalance this noise and accurately adjust the mirrors and other equipment, numerous critical tweaks are essential.

Lana Adhikari from the California Institute of Technology in Pasadena stated that his team has collaborated with DeepMind to innovate new AI methods. He mentions that even automating these adjustments can sometimes introduce noise. “That control noise has puzzled us for decades. All aspects in this space are hindered,” Adhikari explains. “How can you stabilize a mirror without creating noise? If left uncontrolled, the mirror tends to oscillate unpredictably.”

Laura Nuttall from the University of Portsmouth, UK, was involved in manually executing these adjustments at LIGO. “Changing one element causes a cascading effect; one change leads to another,” she points out. “It feels like an endless cycle of fine-tuning.”

DeepMind’s new AI, known as Deep Loop Shaping, aims to minimize noise by making up to 100 adjustments to LIGO’s mirrors. The AI is trained via simulations before being implemented in real-world scenarios, focusing on achieving two main objectives: limiting the number of adjustments it performs. “Over time, as it repeatedly operates, it’s like conducting hundreds or thousands of trials in a simulation. The controller learns what strategies work and identifies the best approach,” says Jonas Buchli from DeepMind.

Alberto Vecchio from the University of Birmingham, UK, expressed enthusiasm for the AI’s role in LIGO but mentioned that many challenges remain. The AI currently operates effectively for only an hour under real conditions, necessitating longer-term validation. Additionally, it’s only been applied to one control aspect, while many hundreds, if not thousands, of factors could assist in stabilizing the mirrors.

“This is clearly an initial step, but it’s certainly a fascinating one. There’s considerable scope for significant advancement,” Vecchio remarked.

If similar enhancements could be replicated elsewhere, it’s possible to detect medium-sized black holes—those around 1,000 times the mass of our sun—a category that has yet to see confirmed observations. Improvements are typically seen with the low-frequency gravitational waves generated by large bodies, where noise can obscure the signals.

“We’ve observed black holes up to 100 solar masses and more than a million solar masses in galaxies. What’s out there in between?” Vecchio pondered. “There’s a perception that black holes exist across a spectrum of masses, yet clear experimental evidence remains elusive.”

Nuttall commented that this new methodology could enhance identification of known black hole types. “This appears quite promising,” she stated. “I’m thrilled about this development.”

Powerful Image Captures the Hidden Struggles of Southeast Asia’s Fishing Industry

Fishermen unload their catch in the Philippines

Nicole Tung

These striking images capture the efforts of photographer Nicole Tung, who dedicated nine months to documenting the human and environmental toll of overfishing in Southeast Asia. Since the 1950s, fishing has rapidly evolved from a traditional craft into a global industry, primarily in developed nations. The rise in overfishing and illegal catch practices is alarming, driven by the increasing demand from a growing population.

Tung emphasizes the significance of the region as a vital part of the global fisheries market. Her project received funding from the €50,000 Kaminyak Photojournalism Award for fieldwork, which shifted her perspective on seafood consumption. Rather than suggesting complete abstention, she advocates for greater awareness and informed choices from consumers.

She expressed her distress over harrowing accounts from Indonesian fishermen, who detailed the violence and dreadful conditions they encounter at sea.

The image above illustrates a fisherman delivering a catch of tuna at General Santos fishport in the Philippines after a month at sea, including Bigger Tuna and Blue Marlin.

Should It Be “Space-Time” or “Space Time”? And Why Does It Matter?

“Even trying to explain ‘space’ feels challenging…”

ShutterStock/FastMotion

One of the most challenging aspects of writing a book is the need for authors to seek out blurbs. These endorsements, prominently featured on book covers, can entice readers to make a purchase. Right now, I’m at this stage with The Edge of Spacetime, reaching out for letters of recommendation, asking people to read my work and share positive thoughts in return for something more than just my good intentions.

It’s a bit nerve-wracking, yet it can also be fascinating. Those whose endorsements get published were asked in a specific format—what prompted you to use “space-time” with a hyphen rather than “spacetime”?

This seems like a question of simple grammar, but there’s a deeper issue at play. When discussing space or time individually, we have an intuitive grasp of what we mean. The term “space-time” is somewhat newer to scientific discourse. Historically, many cultures have embraced a unified concept that doesn’t differentiate between space and time as distinct entities.

For me, as a science communicator, explaining this concept is quite challenging. Even articulating “space” is complex. I might say space is where movement occurs, but movement also happens within time. I could define space as the realm where things exist, but a similar statement can be made for time. We even pondered describing space as a geographical location, yet that sounds overly academic and abstract. Essentially, we are referring to a site of spatial dimensions.

To elucidate, there are three dimensions of space and one dimension of time, but time only flows in one direction.

However, as Albert Einstein famously asserted, these aren’t separate phenomena. Observers moving at varying speeds, especially as they approach the speed of light, may disagree on when certain events transpire. They may also hold differing views on the size of objects. To truly understand everything, we must quantify space-time rather than merely space or time. This perspective might not feel intuitive, but it is the most effective way to comprehend the mechanics of the universe.

In this regard, it’s worth considering whether space-time represents a confluence of two familiar phenomena or signifies the emergence of something entirely new. This is where the nuances of grammar reflect our scientific understanding, at least from my viewpoint.


It’s worth considering whether space-time is a merger of two familiar phenomena or something new.

My last name includes the very first hyphen I encountered. My parents chose to keep both surnames, so to me, Prescod Weinstein signifies both identities.

The hyphenated version of space-time can be interpreted as indicating that what we discuss encompasses both space and time. Conversely, removing the hyphen to form “spacetime” may suggest we are addressing an entirely distinct entity. It embodies attributes of both space and time while existing as a separate third entity.

Are we contemplating something that is both space and time (space-time), or are space and time merely approximations of a fundamentally different conception of space-time? I find myself somewhat ambivalent. In my earlier book, The Blurbriter, I noted this distinction without employing hyphens, thus raising the question of why I chose to make a switch this time around.

The straightforward answer is that the title of the new book appears in the introductory sections of classic cosmology texts. Large-Scale Structure of Space-Time by Stephen Hawking and Father George Ellis states in the very first chapter that solving the equations that describe the universe “in a sense, involves contemplating the edges of space-time.” Just two pages later, they posit that locations where equations deconstruct (like at the heart of a black hole) can be viewed as “representing part of the edge of space-time.”

My book includes chapters that elucidate the types of equations they reference and the role of boundaries and edges in physics. Since I was about to borrow this phrase for my book’s title, I felt compelled to adhere to their terminology.

This is a surface-level explanation. However, at a deeper level, I am unsure where I stand. Like my request for endorsements, I feel inclined to prefer “spacetime” without a hyphen. Yet, I’m also aware of how habitual language can be, given my repeated use of hyphens in the subtitles of my previous work. Scientifically, I lean toward the notion that “space-time” encompasses both space and time, asserting that it is an entirely different fourth dimension: space-time. This may seem like a complex perspective, but I desire to embrace both aspects simultaneously!

Roblox Enhances Age Verification to Limit Adult-Child Interactions | Games

Roblox, the popular gaming platform, is set to restrict communication between adult strangers and children by the end of the year in an effort to eliminate “bad actors.”

With over 110 million users engaged in games like Grow a Garden and Brookhaven RP, the platform has faced scrutiny over child safety as studies have indicated that children can interact with adults during gameplay.

Last month, the platform announced a ban on vigilantes attempting to confront predators. In the previous year, Roblox submitted over 24,000 reports to the National Center for Missing & Exploited Children, addressing allegations of child sexual exploitation in the U.S.

On Wednesday, it was announced that by the end of 2025, all users will be required to utilize text and chat communication tools alongside thousands of games and pass age verification. Users who cannot prove they are over 18 must show that they know who they wish to communicate with. Currently, Roblox mandates proof that the user is over 13 years old to enable communication.

“We’re instituting two major changes,” stated Matt Kaufman, the chief safety officer of the $92 billion gaming company. “By the end of the year, we will require all users with access to Roblox communications to undergo an age verification or estimation process.”

“This process will provide better insight into the user’s age, rather than solely relying on self-reported age at registration. This is especially crucial for younger users, making it imperative to use communication features appropriately based on age.”

The platform continues to expand rapidly, recently allowing companies like Netflix, Lionsgate, and Sega to develop games using their intellectual property on Roblox.

In April, The Guardian published a “deeply intrusive” study highlighting how easily children can encounter inappropriate content and unmonitored interactions with adults. One parent reported that adult strangers could contact their child on the platform, soliciting them to share explicit images. Others have expressed concerns regarding exposure to violent and sexual content, leading to distress for their children.

Roblox stated in a blog post, “Our users, creator community, parents, partners, and lawmakers strive for the same goal as us: to ensure young people remain safe while using Roblox. We are committed to continually innovating and enhancing our safety systems, policies, and moderation tools.”

Ancient Penguins May Have Used Sharp Beaks to Impale Their Prey

Following the Cretaceous Mass Extinction, ancient penguin relatives rapidly diversified

Mark P. Witton/Science Photo Library

Four newly discovered fossil species in New Zealand demonstrate the significant diversity of early penguins, characterized by their long, dagger-like beaks for catching prey.

The latest findings provide “an unexpected insight into the early evolution of penguins,” states Gerald Mayle at the Senckenberg Research Institute in Germany.

The fossils were unearthed from the Waipara Greensand Formation in Canterbury, New Zealand, a region recognized for flourishing after the mass extinction that eradicated non-avian dinosaurs, preserving some of the early avian species that diversified.

“A notable aspect of ancient New Zealand is the lack of terrestrial predators, which enabled early penguins to lose their ability to fly,” explains Mayle. This absence of predators might also clarify why certain early penguins reached sizes as large as humans, he remarks.

In total, Mayr and colleagues detailed four new species, showcasing a remarkable variety of shapes and sizes. Many fossils reveal previously unknown skeletal characteristics; one specimen boasted an exceptionally long back toe, along with an incredibly intact skull and beak.

“Fossils with beaks that provide insight into avian diets are exceedingly rare among penguins from earlier epochs [23 million years ago],” says Tatsuro Ando, who was not part of the study at the Japanese Paleontology Museum.

Present-day penguins feature varied beak shapes tailored to their specific prey, which can include krill and small fish, as well as invertebrates like squid, Ando explains. While these beaks can be short, thick, or curved, they do not compare to those seen in early penguins.

“It appears that ancient penguins utilized their long beaks to grasp their prey,” says Mayle. After impaling the fish, they likely surfaced to toss it into the air and catch it, he adds.

Over a span of approximately 20 million years, penguins evolved to lose their elongated, slender beaks. This change was likely an adaptation to prolonged underwater periods. As they transitioned to a more aquatic lifestyle, their feeding strategies and beak structures also evolved.

The newfound fossils underscore the significance of New Zealand as a “cradle of penguin evolution,” remarked Mayle, indicating that the earliest penguins diversified and spread globally to regions including New Zealand, Antarctica, South Africa, and South America.

“Slap on the Wrist”: Critics Blast Lenient Penalties for Google Following Landmark Monopoly Trial

On Tuesday, the judge ruled that Google would not be required to sell its Chrome browser or Android operating system, a decision that shields the tech giant from the most severe penalties the US government has pursued. This same judge previously sided with US prosecutors nearly a year ago, determining that Google has established and continued an illegal monopoly over its namesake search engine.

Critics of Google’s dominance in the internet search and online advertising arena are outraged. They contend that the judges failed to implement significant reforms in an industry that has been stifled under the immense pressures of leading competitors. Conversely, groups within the tech industry and investors are feeling optimistic. Since Tuesday afternoon, shares of Google’s parent company Alphabet have surged by 9%.

Judge Amit Mehta mandated that Google share data with its competitors and its various search engines. Furthermore, he ordered the company to establish or sustain exclusive agreements for the distribution of its products, such as Chrome, Google Assistant, and the Gemini app. This penalty does not inhibit payment to distributors like Apple or Mozilla, which utilize Google as their default search engine. Google is also facing another hearing later this year regarding its monopoly in online advertising technology.

The Department of Justice heralded the ruling on Tuesday in a press release, calling Mehta’s suggested remedy “crucial.”

“Today, the court’s decision acknowledges the necessity for a remedy to rejuvenate the market for popular search services that has remained stagnant for over a decade,” the statement indicated.

Free market advocates argue, however, that the measures are insufficient.

Critics argue the judge granted Google a lenient victory

Mehta’s verdict has prompted substantial backlash from leading technology critics who have been observing antitrust laws for years. Many organizations and advocacy groups have long advocated for breaking up Google’s exclusive tactics, asserting that robust measures are essential to restoring genuine competition.


Instead of fostering an open online search industry, critics argue that while removing some of Google’s advantages, Big Tech sets a precedent indicating that serious repercussions for legal violations are not to be feared.

“For years, Google has been competing across all facets of the digital economy, overpowering its rivals, stalling innovation, and denying Americans their rights to read, view, and purchase without manipulation by one of the most potent corporations in history,” stated Barry Lynn, executive director of the Open Markets Institute ThinkTank. “The Mehta Order requiring Google to share its search data with competitors and cease exclusive agreements will do little to rectify those issues. It seems that even serious legal violations result in mere wrist slaps.”

Some organizations and analysts have reservations about Mehta’s ruling that Google maintained an illegal monopoly, suggesting that a more favorable decision may be filed this week.

“I would ask him to send a thank-you note to the robbers after finding someone guilty of robbing a bank,” remarked Nidhi Hegde, executive director of the nonprofit American Economic Freedom Project.

Several prominent tech leaders, including Yelp, DuckDuckGo, and Epic Games’ CEOs, criticized the decision, claiming it fails to level the playing field for their competitors. Both Yelp and Epic Games are engaged in legal actions against Google concerning antitrust issues, while DuckDuckGo’s CEO testified during the government’s antitrust trial against the search giant.

“It appears that the accused have committed a string of bank robberies, and the court’s decision has found them guilty and placed them on probation, allowing them to continue robbing banks but requiring them to share data on how the robbery works,” remarked Tim Sweeney, CEO of Epic Games, drawing on the bank robbery analogy.

Democrats advocating for stricter regulations on big tech companies have similarly condemned the ruling, with some calling for the Department of Justice to appeal the decision.

“The court previously determined that Google’s search operations constituted an illegal monopoly, but now the judge’s remedies do not hold Google accountable for violating the law,” stated Massachusetts Senator Elizabeth Warren in a statement. “Instead of reinstating competition and curtailing Google’s dominance, this ruling serves as a mere wrist slap for illegal behavior that ensures this tech giant remains intact.”

The chairs of the Monopoly Busters Caucus—US Representatives Chris Deluzio, Pramila Jayapal, Pat Ryan, and Angie Craig—issued a statement condemning the ruling as a “wrist slap,” arguing it undermines bipartisan efforts to tackle tech monopolies.

“This ruling effectively permits Google to retain its monopoly. Despite Google’s illegal actions regarding its search monopoly, the courts are allowing it to keep Chrome and Android, which are essential tools for Google’s market control,” the Caucus asserted.

Human rights organization Amnesty International also expressed outrage at the decision, highlighting that Google’s business model is fundamentally flawed. They emphasized that Chrome is a critical tool utilized for collecting personal data from Google users.

“Google’s infringement on the search industry and the imposition of a sale on Chrome could have signaled the initial step toward a digital landscape that respects our rights,” stated Agnès Callamard, executive director of Amnesty International.

Silicon Valley and Wall Street celebrate

The tech sector rejoiced while antitrust advocates lamented the verdict. Industry groups stated that Mehta’s ruling prevented a potential disaster for Silicon Valley. The Developers’ Alliance, a high-tech industry group, praised the judge for rejecting the severe structural relief sought by the Justice Department.

“The sale of Chrome and Android would have had catastrophic implications for web and app developers and the broader digital ecosystem,” the group stated. “Developers are relieved that this trial’s political theatrics have reached a conclusion.”

Another industry organization, the Consumer Choice Center, supported Google’s claim that its products are superior, justifying its market control. Stephen Kent, the group’s media director, likened the Justice Department’s “politicized incident” to a larger player enjoying popularity due to offering superior products rather than competing apps and services.

Many of these organizations referenced Mehta’s assertion that, over the years, Google has given rise to technically viable competitors within Chrome. “This new reality illustrates that if a strong competitor arises, Google should not be expected to outweigh them in distribution,” the judge’s ruling indicated.

“The debate around search engine market shares is particularly relevant in light of the dramatic and significant advancements in AI that are reshaping the landscape,” remarked the Developer Alliance.

Jennifer Huddleston, a senior fellow at the Libertarian Think Tank The Cato Institute, advised careful consideration, emphasizing that “innovation often remains our best competitive strategy.”

“The month between the initial ruling and the remedial decision underscores the rapid changes occurring in the tech industry,” Huddleston noted. “This is especially true considering the transformative nature of AI technologies in search. As Judge Mehta points out, courts must not only analyze historical facts but also forecast the future in a swiftly evolving market.”

Apple also experienced a boost, with Google’s stock rebounding following Mehta’s ruling. Historically, the iPhone manufacturer has received billions from Google annually, as Google serves as the default search engine for its devices. The arrangements between the two companies account for approximately 15% of Apple’s operating profits. Shares have risen nearly 4% since Tuesday.

“We’ve been eager to get started,” wrote Gene Munster, managing partner at Deepwater Asset Management, on X.

Critics of the ruling are not surprised that Wall Street has responded positively to Mehta’s decision. “There’s a reason Google stock skyrocketed following this ruling,” stated Christo Wilson, a professor of Computer Science at Northeastern University, who led a team that studied Google’s monopolistic practices in search. “This represents a historic failure to address the significant evidence that Google is an online search monopoly.”

Our New Vision for the Future Has Run Its Course and Needs Revamping

The 20th century was a vibrant era for future visions, yet the 21st century has not sparked the same enthusiasm. Sci-fi author William Gibson, known for his groundbreaking cyberpunk work Neuromancer, refers to this phenomenon as “Future fatigue”, suggesting we seldom mention the 22nd century.

This stagnation is partly due to the evolution of many iconic future concepts from the 20th century. For instance, plastic was once hailed as the material of the future. Although it has proven to be durable, versatile, and plentiful, its properties now pose significant environmental and health concerns.

Today’s predominant future imagery carries a legacy of historical influence. Themes such as space colonization, dystopian AI, and a yearning for an imaginary past persist, often shaped by the climate anxiety many people experience. The future begins to feel like a closed book rather than an open road.

Jean Louis Missica, former vice mayor of Paris, articulated it well in his writing: “When the future is bleak, people idealize past golden ages. Nostalgia becomes a refuge amid danger and a cocoon for anticipated decline.”

Another factor contributing to this stuck imagery is social media, which exposes users to a vast array of different time periods at once, fostering nostalgia and a continuous remixing of existing ideas.

However, new visions of the future have emerged this century. For example, the climate aspiration movement gained traction on Tumblr and blogs in the 2000s. Yet, as smartphones became our primary mode of communication, the collective imagination surrounding our vision of the future waned.

I reflect on the future of living, drawing from my experience that a cohesive vision can motivate individuals to drive change. Such visions serve as engines of inspiration and imagination. They enable us to envision the society we aspire to create and commit to working towards that future. Movements like Civil Rights have long recognized this. A unified future vision also manifests effectively in architecture, advertising, and television, with Star Trek inspiring engineers for decades.

As we transition from fossil fuels to renewable energy, we find ourselves in a transformative era. This period is daunting yet invigorating. Numerous hotspots of innovation are emerging, such as rooftop solar energy in Pakistan, where households and small businesses actively adopt renewable energy solutions, or the global initiatives like Transition Town, rethinking local economies and cultures.

Nevertheless, we lack a unified vision that integrates these innovations, embedding them within a social context and building pathways from the present to the future.

In my new book, I explore four visions for the future currently taking shape: DeGrowth, which reevaluates our economic roles; SolarPunk, which revitalizes cultural innovation; the Metaverse, which immerses us in a vibrant digital universe; and movements that encourage us to rethink our relationship with nature.

Yet, the future won’t stop evolving. We must cultivate and nurture more emerging visions, allowing them to take shape as we redefine our narrative of what the future could be.

Exploring Love’s Work: Insights from Psychoanalysis on Love and Heartbreak

Psychoanalysts Can Aid Couples in Clarifying Relationship Concerns

Carl Navarro Percesus/Getty Images

Labour of Love
Stephen Grosz (UK: Chatto & Windus, Available Now; US: Random House, February 10, 2026)

Psychoanalysts, with their deep understanding of human emotions, might seem to enjoy relationships devoid of the tumult that often impacts our romantic endeavors.

However, in his compelling memoir, Labour of Love, Grosz delves into over 40 years of discussions about love with his patients, observing the intricate web involving four of his colleagues. At first, Susan and Paul appear to be a blissfully married couple, just like Kora and Martin, until it’s revealed that Paul and Kora have maintained a secret affair for two years.

The ensuing critique strikes at the very essence of their profession. “I’ve never fully grasped what it means to be a psychoanalyst,” Susan confides to Kora. “I possess empathy, I care for others, I establish boundaries, I perceive reality. Avoid taking your friend’s husband.” For Susan, psychoanalysis seems to focus on accountability and self-regulation. Kora, on the other hand, believes her journey is about achieving complete self-awareness. To her, psychoanalysis serves the purpose of intentional self-discovery.

Grosz reflects on these paradoxes, arriving at ambiguous conclusions. He suggests that while psychoanalysis may target both objectives, neither should be a primary aim. “It benefits the patient and enhances her well-being. However, these goals may obscure the hidden desire to restrict the patient’s freedom,” he states. Psychoanalysts enable their patients to gain insights into their minds, but how they utilize that understanding remains their own decision.

Skeptics might contend that psychoanalysis lacks scientific validity. After all, how can one measure the effectiveness of interventions on mental processes? Initially pioneered by Sigmund Freud, psychoanalysis employs informal dialogues to uncover unconscious dynamics, often involving extended discussions that may last for years, including in-depth explorations of childhood. This contrasts sharply with cognitive behavioral therapy (CBT), which utilizes specific exercises aimed at altering immediate thoughts and behaviors, such as more aggressive strategies to “reconstruct” experiences.


Grosz has drawn comparisons to Anton Chekhov and Oliver Sacks.

Nowadays, CBT is often the preferred initial treatment for various mental health issues, yet clinical trials indicate that psychoanalysis effectively enhances well-being. Labour of Love offers a captivating exploration of this process through the stories of Gross’s patients and acquaintances.

Take Sophie, for example. When Gross first meets her, she’s engaged, but despite her hopes for a future marriage, she hesitates to send out any invitations. She is plagued by haunting dreams about her parents’ demise. Together, they eventually trace this fear back to her parents and their loss, which occurred before Sophie was born. She dreads any changes that might separate her from them.

Often, individuals’ issues stem from a fear of losing their identity. “A crucial distinction exists between surrendering to something (or someone) and submitting to it,” Gross asserts. Submissions equate to transactions and involve relinquishing control, whereas mutual surrender fosters vitality, empowerment, and acceptance. In that space, love can flourish.

The journey to comprehend Labour of Love is not straightforward. As the title implies, understanding both ourselves and our beloved requires consistent effort.

Grosz is a compelling writer whose thoughtful narratives frequently illuminate the complexities of human experiences. A review of his earlier work, Researched Life, likened him to literary figures such as Anton Chekhov and Oliver Sacks. His storytelling shines particularly when illustrating the intertwined lives of fellow psychoanalysts. For instance, during Cola’s death, Paul connects deeply with Cola’s family while sitting shiva. In this poignant moment, he finds solace in Susan’s presence.

This scene encapsulates the contradictions inherent in love, as Grosz elaborates: “Susan and Paul loved, resented, married, and divorced. Yet, even during this challenging period, they remained a couple. Their love continued to evolve.”

The Pioneering Map of Mammalian Brain Activity Might Have Revealed Intuition

Map of mouse brain showing 75,000 neurons

Dan Berman, International Brain Research Institute

The initial comprehensive activity map of the mammalian brain has unveiled groundbreaking revelations regarding decision-making processes.

For many years, neuroscientists aspired to capture neuronal activity throughout the brain at an individual level. However, challenges persist, including the limitations on the number of neurons an electrode can record, the number of electrodes deployable in a single brain, and the number of animals that a solitary lab can study.

To address these hurdles, a collaboration among 12 laboratories is underway, with each conducting identical experiments and recording duplicates to ensure consistency in collected data. This joint effort, tracking the activity of over 650,000 neurons, has resulted in the first comprehensive brain activity map related to complex behaviors.

“This research exemplifies a novel approach to addressing intricate inquiries in contemporary neuroscience,” stated Benedetto de Martino of University College London, who was not a part of this study. “Similar to CERN, which unites physicists to tackle profound issues in particle physics, this project will bring together global laboratories to confront challenges too expansive for individual teams.”

In each facility, mice were trained to maneuver a small LEGO steering wheel to direct a striped target towards the center of the display. The target was easily distinguishable when the stripes contrasted sharply. As contrast dwindled, the target nearly vanished, compelling the mice to rely on prior knowledge to respond accurately for a reward.

Bias was factored into the experiment, impacting the mice’s expectations about the target’s location. For instance, it could appear on either side of the screen. When the bias was inverted, the mice adjusted their expectations accordingly.

The resulting activity map indicates that decision-related processes are dispersed throughout the brain, rather than localized in one specific area. “Many assertions claimed, ‘this region is responsible for this function.’ However, our findings reveal that decision-making involves numerous regions collaborating through a consensus,” remarked team member Alexandre Pouget from the University of Geneva, Switzerland.

Furthermore, the findings support earlier research indicating that decision-related signals form long before an action is executed. Pouget noted that even prior to the commencement of individual experiments, signals linked to forthcoming decisions are evident. These signals accumulate when the target is presented, prompting the mice to move the wheels until a threshold is reached.

The second study reveals that beliefs regarding the target’s position are encoded very early in the brain’s activity. Researchers discovered that whether the signal emerged from the eye or journeyed to the thalamus, the brain’s relay center, advanced expectations regarding the target’s left or right positioning were already established.

This suggests that from the moment sensory information is processed by our brains, it is inherently influenced by knowledge, altering the conscious decision-making process unconsciously, according to Pouget. “While speculative, this may align with what we interpret as intuition,” he added.

Interestingly, the encoding not only captures recent sensory experiences but also seems to document the recent history of choices made. Lawrence Hunt from Oxford University pointed out, “This indicates that our actions and subjective experiences shape our perceptions, rather than the true objective reality.”

Does this imply our decisions are predestined? “The brain and its environment operate as a deterministic system. People often resist this idea, but it is accurate,” Pouget stated. “This means one can predict, to an extent, what actions will be taken before a decision is made. Nevertheless, when new information arises, expectations must be recalibrated, remaining unaware of how the surrounding world will evolve,” he explained.

Looking ahead, researchers are optimistic that the findings and collaborative methodologies will enhance the understanding of conditions like autism. A mouse model of autism suggests these animals struggle to update previous expectations with new information, according to Pouget, which resonates with our behaviors and perceptions.

Queen Ant Produces New Male Species for Daughter’s Mating

Male ants of distinct species laid by the same mother: Messor ibericus (left) and Messor structor (right)

Jonathan Romiguier

In the clutches of the Iberian Harvester Ant queens, another male species, the Builder Harvester Ant, emerges. These males are responsible for siring all the workers in the colony.

“This assertion appears utterly unbelievable, akin to the impossible,” remarks Jonathan Romiguier from the University of Montpellier, France. Nonetheless, he has confirmed its validity.

Romiguier’s curiosity was piqued by the Iberian harvester ants (Messor ibericus) after he discovered that all the workers were hybrids. About half of their DNA aligned with that of the builder harvester ant (Messor structor).

The most plausible explanation is that the queen of M. ibericus mated with a male of M. structor. This occurrence is seen in other ant species. The reasons remain unclear, but two main theories have emerged. One is that hybrids of closely related species could benefit from what’s known as hybrid vigor, where various genes can compensate for each other’s deficiencies.

Another theory suggests this may address a peculiar challenge faced by M. ibericus and several other harvester ant species: whenever M. ibericus queens mate with males of their own species, all offspring become queens. This might stem from a genetic tendency to secure their lineage, but it becomes detrimental for colonies that need worker ants for survival. Breeding with another species may provide a solution.

However, M. ibericus colonies are widespread across various Mediterranean locales, unlike M. structor colonies, which are exclusive to Sicily. Nonetheless, Romiguier and his team encountered peculiar, hairless males of M. structor within an M. ibericus nest. So, where did they originate?

The genetic examination of these unusual males yielded perplexing insights. A tiny segment of the mitochondrial DNA—passed solely from the mother—indicated that these males derive from the M. ibericus queen.

This hinted that the eggs produced by the queen of M. ibericus could encompass males of a different species. To verify this theory, Romiguier brought several M. ibericus colonies into his lab. “Under laboratory conditions, it’s nearly impossible to find a male,” he comments. “We maintained about 50 colonies and observed one male for two years without success. Then, fortune smiled upon us.”

From three M. structor males born in the lab, the evidence was undeniable: the queen of M. ibericus produced males from both species. The only explanation for this phenomenon is that the queen ant cloned M. structor males using stored sperm in specialized organs called spermathecae. The resulting eggs were almost entirely devoid of M. ibericus DNA, except for its mitochondrial component.

This also clarifies the origin of M. structor sperm: by producing two types of males, the queen guarantees that her daughters who evolve into queens can mate with both male types. The females use M. ibericus sperm to generate new queens, while M. structor sperm is utilized for hybrid workers and new male ants.

There are notable instances from other species—including ants, mollusks, and stick insects—where female eggs are manipulated by male sperm from different species, leading to the elimination of egg DNA and the production of unrelated individuals. However, this scenario mainly benefits males. This is the sole known instance where both male and female offspring from distinct species rely on each other for reproduction.

“The queen of M. ibericus is entirely dependent on her cloned males. Without them, she cannot produce workers,” states Romiguier. Moreover, the clones of M. structor need the males of M. ibericus for rearing workers and sustaining their colonies—there is no sign that they mate exclusively within their species.

While these findings may seem far-fetched, they have garnered the support of other specialists. “The researchers conducted thorough investigations into these ants,” comments Nathan Law from the University of Sydney. “Their results robustly affirm their conclusions.”

He speculates that cloned males could accumulate harmful genetic mutations that may not be purged over time due to the lack of interbreeding with other strains. “Eventually, this system may start to decline, especially as environmental conditions shift.”

Romiguier agrees that this exceptional situation might eventually lead to collapse. Yet, at present, it appears that M. ibericus and M. structor have navigated their relationship with ingenious adaptability, propelling their expansion throughout the Mediterranean, while M. structor colonies have not established themselves elsewhere.

It Could Have Up to 90% Less Carbon Storage Capacity Than You Realize

Icelandic geothermal power facilities engaged in the underground injection of carbon dioxide for extended storage

sigrg/carbfix

Recent studies indicate that the planet may exhaust its capacity for storing captured carbon dioxide within the next 200 years, revealing that our ability to retain CO.2 underground is significantly less than previously believed.

Government and industry advocates promote the underground storage of carbon dioxide as a viable solution to achieving net-zero emissions while still utilizing fossil fuels.

Previously estimated industry figures suggested a global geological storage capacity of about 14,000 Gigatonnes of CO.2. However, as noted by Jori Rogelj from Imperial College London, UK, this capacity was thought to be effectively limitless.

Through comprehensive analysis, Rogelj and his team discovered that the actual available storage space might be considerably lower. By assessing stable geological formations while excluding areas with significant risk factors, such as proximity to major urban centers, sensitive ecosystems, or regions prone to earthquakes, they concluded that only 1460 Gigatonnes of geological storage capacity is viable worldwide.

“From a situation where storage options appeared virtually boundless, we’ve transformed our perspective,” Rogelj explains. “The storage potential we can depend on requires careful management and represents a crucial asset,” he continues, emphasizing that the potential is now ten times more valuable than previously recognized.

Most climate projections indicate that adequate underground carbon storage is essential for the world to attain net-zero emissions. The extent of this storage relies fundamentally on reducing fossil fuel consumption. Researchers caution that if we continue to depend on geological storage to isolate significant emissions post-net zero, we could deplete carbon storage entirely by the year 2200.

Rogelj asserts that his findings suggest underground carbon storage should only be utilized as a last resort when all other options have been exhausted. He recommends relying on zero-emissions solutions whenever feasible, rather than capturing and storing emissions from fossil fuel power stations.

This strategy would preserve underground storage capacity for CO2 that could be utilized with technologies such as direct air capture (DAC), which extracts excess CO2 directly from the atmosphere. DACs, along with other “negative emissions” technologies, can potentially help the world achieve net negative emissions beyond reaching net zero, opening up pathways to effectively reverse climate change.

According to Rogelj and his colleagues, the 1460 Gigatonnes of accessible underground CO2 storage capacity could allow the world to counteract warming by as much as 0.7°C.

Nonetheless, Stuart Haszeldine from the University of Edinburgh warns that the actual usable geological storage capacity might be less than the industry’s 14,000 Gigatonnes estimate and suggests that these revised lower figures could still be overly optimistic.

He argues that the team’s approach to evaluating risk factors is “quite conservative,” pointing out that certain seismic regions, such as the North Sea, have been excluded from consideration but remain suitable for carbon isolation. “We understand enough about carbon storage and oil reserves. An oil field filled with oil, gas, or carbon dioxide can withstand quakes of magnitude 6 without any issues,” Haszeldine states.

He emphasizes that most analysts foresee carbon sequestration as an integral part of the transition away from fossil fuels. Therefore, he predicts that the volume of carbon injected underground yearly should diminish once net-zero emissions are achieved.

“[Carbon capture and storage] encompasses a wide range of climate pessimism and challenges, which have often been overlooked, explaining why we don’t really require a tremendous amount of joint CO2 storage capacity,” Haszeldine concludes.

Using a Smartphone While on the Toilet May Raise Bleeding Risks

It may be wise to keep your phone out of the bathroom

Ekaterina Demidova/Getty Images

Do you find yourself using your smartphone while on the toilet? If that’s the case, you might be spending more time there than anticipated, which could increase your risk of bleeding by nearly 50%.

“Our gastroenterologists consistently advise patients, ‘Limit your time in the bathroom,'” says Trisha Pasricha from Beth Israel Deaconess Medical Center in Boston, Massachusetts. “However, upon exploring the literature, I discovered substantial data backing this advice.”

Pasricha and her team are currently conducting their own study, asking 125 individuals scheduled for colonoscopy to complete a questionnaire regarding their bathroom habits, overall health, and physical activity. They then analyze the colonoscopy images to check for signs of bleeding, also referred to as a mass in the lower region.

“These conditions can be quite challenging for individuals to identify on their own,” Pasricha explains. “Sometimes they are internal and may not be felt, and what may be perceived externally doesn’t always correlate with actual bleeding.”

Among participants over 45, two-thirds reported using their smartphones in the bathroom. “If we surveyed college students, I suspect almost no one would skip bringing their phones to the restroom,” Pasricha remarked.

The study revealed that 37% of individuals who used smartphones in the bathroom averaged five or more minutes spent in there, whereas only 7% of non-users spent the same duration. Thus, phone users were about five times more likely to linger for five minutes or longer.

However, most participants seemed unaware of this, with only 5% acknowledging that smartphone usage extended their time spent in the bathroom. The data did not show any significant correlation between the participants’ gender and the time spent on the toilet.

After adjusting for age and physical activity levels, the research team concluded that smartphone use in the bathroom correlated with a 46% increase in bleeding risk. “It’s important to clarify that our study doesn’t establish a cause-and-effect relationship,” Pasricha noted. Moving forward, future research will involve interventions, asking some participants to refrain from using their phones while in the restroom.

The research also found no connection between tension and bleeding risk. This might seem surprising given common beliefs; however, the existing evidence is quite limited. In fact, some studies have indicated that the risk of bleeding correlates more with diarrhea rather than constipation.

Pasricha’s research suggests that the main risk factor is the prolonged time spent seated on the toilet. The consensus is that this position offers less pelvic support compared to sitting on a flat surface. “This leads to a passive rise in pressure affecting these muscles due to the lack of pelvic floor support,” she explained.

Lucinda Harris at the Mayo Clinic in Arizona agrees, noting that long durations in the bathroom can mimic the pressure experienced during pregnancy in the pelvic region.

If these findings hold true, the widespread use of smartphones might be contributing to increasing rates of bowel issues globally. Diagnosing such conditions can be tricky, so it remains unclear if the incidence rates are truly changing, Pasricha pointed out. Additionally, dietary changes could also be influencing these rates.

Pasricha advises keeping your smartphone outside the bathroom, although reading materials that aren’t designed to be addictive might be acceptable. “Consider reading things that promote moderation, and keep track of your time,” she suggested. Financial Times

Why Solar Power is the Most Sustainable Energy Source for the Future

Only 0.3% of the Earth’s land area needs solar panels to fulfill all energy requirements

VCG via Getty Images

Solar energy has been gaining traction for years, and it’s easy to see why. It represents one of the most economical ways to produce energy almost anywhere and stands as a vital measure against climate change.

However, there are skeptics. U.S. Energy Secretary Chris Wright asserts that solar energy cannot meet global energy demands. Many experts highlight that this claim is fundamentally misguided. Over time, sunlight—along with wind energy—offers the only reliable power source capable of satisfying escalating energy demands without harming the planet.

On September 2nd, Wright posted on social media platform x, stating, “Even if we covered the entire planet with solar panels, it would only generate 20% of the world’s energy. One of the greatest mistakes politicians make is equating electricity with energy!”

First and foremost, electricity is quantified based on the energy it delivers, making it practical to consider electricity as equivalent to energy.

Climate scientist Gavin Schmidt from NASA’s Goddard Space Research Institute remarked on Bluesky that the total energy content utilized by all fuels globally in 2024 was approximately 186,000 terawatt hours. He emphasized that the Earth receives 6,000 times that amount in energy each year.

Moreover, Schmidt noted that since 60% of fossil fuel energy is typically wasted in the conversion process to usable electricity, the Earth receives 18,000 times more energy than is needed to satisfy current energy consumption levels.

While existing solar panels only capture around 20% of available solar energy and can’t be installed everywhere, a 2021 report by Carbon Tracker estimated that merely 0.3% of the world’s land area (limited to land) is required to address current energy needs through solar energy alone. This footprint is smaller than that of existing fossil fuel infrastructure. In essence, the report indicates that solar and wind can provide over 100 times the current global energy demand.

We are fortunate, as the current reliance on fossil fuels is already contributing to hazardous climate change with fossil fuels alone supplying 100 times more energy than the planet can sustainably handle. But what about nuclear fusion? If it becomes a feasible option, would it surpass solar energy?

The answer is negative. Eric Chaisson from Harvard University anticipates minimal growth in global energy demand; however, the waste heat generated could potentially elevate global temperatures by 3°C within three centuries. This refers to waste heat from everyday activities like boiling a kettle or using a computer, which consumes the energy produced.

Solar energy—along with wind, tides, and waves—functions fundamentally as a source harnessed from the sun, rendering waste heat irrelevant. The energy we utilize, whether it ends up as waste heat or not, determines its practical value. In contrast, other energy sources, like nuclear fission, do not currently address waste heat management.

“[Carl] Sagan preached to me, and I now relay that message to students. Any planet must ultimately utilize the energy it possesses,” Chaisson remarked in an interview with New Scientist in 2012.

Though three centuries is a long time, the implications of waste heat are already significant. Studies indicate that maximum temperatures in Europe’s summers have increased by 0.4°C. By 2100, average annual temperatures in certain industrialized regions may rise by nearly 1°C due to waste heat—effects not currently considered in climate models.

Ultimately, the only technology that can sustainably harness solar and wind energy to meet global energy demands for centuries, without triggering catastrophic warming, is these renewable sources. The projections couldn’t be more misguided.

Plant-Based Dog Foods Offer Nearly All Essential Nutrients for Your Pet

Plant-based and meat kibbles might both be deficient in crucial nutrients

Snizhana Halytska/Alamy

To ensure a balanced diet, vegetarian and vegan dog foods need specific adjustments.

Research indicates that meat-free dry kibble fulfills dogs’ protein and fat needs but is typically short on iodine and vitamin B. With the right supplements or improved commercial options, plant-based dog foods can maintain pets’ health while minimizing the ecological footprint of the pet food industry Rebecca Broseyk from the University of Nottingham, UK.

“Provided they get all necessary nutrients from their food, dogs will thrive,” she explains.

Many vegans and vegetarians who have dogs often grapple with the ethics of feeding meat to carnivorous pets David Gardner at the University of Nottingham. In light of this concern, manufacturers are beginning to offer plant-based options.

Organizations such as the European Federation of Pet Food Industry and the American Association for Feed Management are advocating for standardized assessments of commercial pet foods and additives to guarantee nutritional adequacy. Nonetheless, most pet foods globally lack thorough nutritional evaluations by independent experts, according to Gardner.

Brociek, Gardner, and their team examined 25 types of commercially available dry foods for healthy adult dogs, of which 19 were formulated with either meat or plants. Among these, two were labeled vegetarian and four were vegan.

Researchers assert that although marketed as nutritionally complete, none of the official dog dietary guidelines were entirely met. However, all foods did manage to provide appropriate levels of protein, fatty acids, and essential amino acids.

The majority, including five out of six plant-based options, fell short on iodine, although seaweed served as a beneficial remedy for these deficiencies.

The vitamins were generally sufficient, except for vitamin B, which was especially deficient in plant-based options. Dogs lacking vitamin B can experience skin, nerve, and digestive issues, suggesting that manufacturers should bolster their formulations, the researchers state.

The results indicate a need for oversight in dog food production across all types, not just those that are plant-based. Andrew Knight from Murdoch University, Australia, stresses, “Consumers expect that if a product claims to be nutritionally healthy, it should be accurate, but that’s often not the case.”

“A vegetarian diet can be beneficial if nutrients lacking in plant sources are adequately replaced, similar to the considerations for humans choosing vegetarian diets,” says Lucia Casini from the University of Pisa, Italy, who adds that pet owners should refrain from making their own plant-based meals for their pets.

Dogs have evolved to consume a variety of foods, so a well-rounded plant-based diet can fulfill their nutritional needs, which can also lower the environmental impact associated with meat production, including greenhouse gas emissions, according to Gardner.

“They are genuine omnivores,” he remarks. “As many Labrador owners (myself included) will attest, they will eat just about anything.”

It Bans Social Media While Embracing AI, Leaving Teens Disappointed

While someone in their 70s didn’t serve in World War II, this statement holds truth, as even the oldest Scepter Agerians were born post-war. Yet, a cultural link persists between this demographic and the era of Vera Lynn and the Blitz.

When discussing parents and technology, similar misconceptions arise. The prevailing belief is that social media and the internet are a realm beyond the understanding of parents, prompting calls for national intervention to shield children from tech giants. This month, Australia plans to outline its forthcoming restrictions. However, the parents of today’s teens are increasingly digitally savvy, having grown up in the age of MySpace and Habbo Hotel. Why have we come to think that these individuals can’t comprehend how their kids engage with TikTok and Fortnite?

There are already straightforward methods for managing children’s online access, such as adjusting router configurations or mandating parental approval for app installations. Yet politicians seem to believe these tasks require advanced technical skills, resulting in overly broad restrictions. If you could customize your Facebook profile in college, fine-tuning some settings shouldn’t be beyond reach. Instead of asking everyone to verify their age and identity online, why not trust the judgment of parents?


If you customized your Facebook page in university, you should be able to tweak a few settings

Failing to adapt to generational shifts can lead to broader issues. Like veterans who narrowly focus on historical battles from the past, there’s a risk of misdirecting attention. While lawmakers clamp down on social media, they’re simultaneously rushing to embrace AI technologies that rely on sophisticated language models, which significantly affect today’s youth, leaving educators pondering how to create ChatGPT-proof assignments.

Rather than issuing outright bans, we should facilitate open discussions about emerging technologies, encompassing social media, AI, and their societal implications while engaging families in the conversation.

Parents Can Receive Alerts If Their Child Experiences Acute Distress While Using ChatGPT | OpenAI

When a teenager exhibits significant distress while interacting with ChatGPT, parents might receive a notification if their child displays signs of distress, particularly in light of child safety concerns, as more young individuals seek support and advice from AI chatbots.

This alert is part of new protective measures for children that OpenAI plans to roll out next month, following a lawsuit from a family whose son reportedly received “months of encouragement” from the chatbot.

Among the new safeguards is a feature that allows parents to link their accounts with their teenagers’, enabling them to manage how AI models respond to their children through “age-appropriate model behavior rules.” However, internet safety advocates argue that progress on these initiatives has been slow and assert that AI chatbots should not be released until they are deemed safe for young users.

Adam Lane, a 16-year-old from California, tragically took his life in April after discussing methods of suicide with ChatGPT, which allegedly offered to assist him in crafting a suicide note. OpenAI has acknowledged deficiencies in its system and admits that safety training for AI models has declined throughout extended conversations.

Raine’s family contends that the chatbot was “released to the market despite evident safety concerns.”

“Many young people are already interacting with AI,” OpenAI stated. The blog outlines their latest initiatives. “They are among the first ‘AI natives’ who have grown up with these tools embedded in their daily lives, similar to earlier generations with the internet and smartphones. This presents genuine opportunities for support, learning, and creativity; however, it also necessitates that families and teens receive guidance to establish healthy boundaries corresponding to the unique developmental stages of adolescence.”

A significant change will allow parents to disable AI memory and chat history, preventing past comments about personal struggles from resurfacing in ways that could exacerbate risk and negatively impact a child’s long-term profile and mental well-being.

In the UK, the Intelligence Committee has established a Code of Practice regarding the design of online services that are suitable for children, advising tech companies to “collect and retain only the minimum personal data necessary for providing services that children are actively and knowingly involved in.”

Around one-third of American teens utilize AI companions for social interactions and relationships, including role-playing, romance, and emotional support, according to a study. In the UK, 71% of vulnerable children engage with AI chatbots, with six in ten parents reporting their children believe these chatbots are real people, as highlighted in another study.

The Molly Rose Foundation, established by the father of Molly Russell, who took her life after succumbing to despair on social media, emphasized that “we shouldn’t introduce products to the market before confirming they are safe for young people; efforts to enhance safety should occur beforehand.”

Andy Burrows, the foundation’s CEO, stated, “We look forward to future developments.”

“OFCOM must be prepared to investigate violations committed by ChatGPT, prompting the company to adhere to online safety laws that must ensure user safety,” he continued.


Anthropic, the company behind the popular Claude chatbot, states that its platform is not intended for individuals under 18. In May, Google permitted children under 13 to access its app using the Gemini AI system. Google also advises parents to inform their children that Gemini is not human and cannot think or feel and warns that “your child may come across content you might prefer them to avoid.”

The NSPCC, a child protection charity, has welcomed OpenAI’s initiatives as “a positive step forward, but it’s insufficient.”

“Without robust age verification, they cannot ascertain who is using their platform,” stated senior policy officer Toni Brunton Douglas. “This leaves vulnerable children at risk. Technology companies should prioritize child safety rather than treating it as an afterthought. It’s time to establish protective defaults.”

Meta has implemented protection measures for teenagers in its AI offerings, stating that for sensitive topics like self-harm, suicide, and disability, it will “incorporate additional safeguards, training AI to redirect teens to expert resources instead.”

“These updates are in progress, and we will continue to adjust our approach to ensure teenagers have a secure and age-appropriate experience with AI,” a spokesperson mentioned.

Trump’s Billion-Dollar Fortune: Guns, Family, and the Rise of Corporate Crypto Tokens

World Liberty Financial, a cryptocurrency initiative by the Trump family, launched its digital token on Monday, which reportedly added around $5 billion in paper wealth to the family’s fortune. The token, named $WLFI, experienced a drop in value on its opening day.

The global Liberty Token was introduced to investors following the Trump family’s partnership with business associates to create a decentralized finance platform last year, which issued Stablecoin intended to stabilize its price by pegging it to a specific asset.

Investors in the token will have the opportunity to vote in July to permit trading, which may enhance the value of the president’s assets.

According to World Liberty, early backers can liquidate up to 20% of their holdings. The token debuted trading above $0.30 on Monday, but its price subsequently declined to $0.20. Data from CoinMarketCap indicates that nearly $1 billion worth of tokens were exchanged within the first hour of trading.

This brings the token’s market capitalization to below $7 billion, classifying it as the 31st largest cryptocurrency in circulation, as per analytics from Coingecko.

Major global cryptocurrency exchanges such as Binance, OKX, and Bybit are listing $WLFI tokens on their platforms.


Since the inception of World Liberty last year, the Trump family is reported to have earned approximately $500 million from the venture, according to calculations by Reuters, which are based on contract terms, transactional data from crypto analysis firms, and publicly available records.

Holding around 25% of the global Liberty tokens has reportedly contributed about $5 billion to the Trump family’s wealth, as noted by the Wall Street Journal. World Liberty states that Trump himself possesses an unspecified amount, referred to on the company’s site as “co-founder honor,” but, like other team members, including his son, he is prohibited from selling them. Trump utilized the Oval Office to advocate for U.S. regulations favorable to the industry.

On the initial sale, the tokens were non-tradable. Instead, they granted holders voting rights for various business modifications, including adjustments to the underlying code. Early investors highlight that the primary allure of $WLFI lies in its association with Trump, fostering expectations that its value will appreciate through his endorsement.

Making the tokens tradable allows investors to set prices, speculate effectively, accrue trading fees for exchanges that list them, and draw the interest of a broader spectrum of cryptocurrency investors compared to when they were solely personally accessible.

World Liberty and other Trump-backed cryptocurrency endeavors exemplify a significant conflict of interest as the president revises regulatory frameworks governing digital currency, which has drawn criticism from Democrats and ethics experts regarding Trump’s involvement in cryptocurrency enterprises.

The White House has consistently asserted that Trump’s assets are managed through a trust, claiming there is no conflict of interest.

A New Wave of Unannounced Archaeology Games Inspired by the Forgotten Tomb Raider

The game I’m eagerly anticipating at the moment is Big Walk, the newest creation from House House, the developers behind the beautiful Untitled Goose Game. This cooperative multiplayer adventure invites players to explore an expansive world, and I’m excited to see what intense gameplay arises from it. Will Big Walk allow for a unique form of community archaeology with friends? I genuinely hope so.

From the placement of objects to audio recordings and graffiti, if the game effectively employs environmental storytelling, it encourages players to embody the role of archaeologists. Game designer Ben Esposito characterized environmental storytelling in 2016 as “the technique of placing a skull near a toilet.” This might have been a critique directed at games like the Fallout series, but his quick remark illustrates how an archaeological narrative can unfold within a game. After all, the contrast between the skull and the toilet can provoke numerous questions and interpretations about the past within that game world, albeit a rather absurd one.

I have worked as an archaeologist in the tangible world, where I was involved in excavations, fieldwork, and site evaluations across the UK. Currently, I’m pursuing a PhD in Computer Science with a focus on video game archaeology. We are developing innovative methods to document gameplay experiences, including conducting in-game interviews with players and tracking in-game messages in Elden Ring.

Given my background, I often find myself contemplating the games where you play roles akin to an archaeologist, whether as a grave robber or an unknown entity, as well as those that simulate the tasks we perform in the field. Games like What Remains of Edith Finch encourage players to immerse themselves in the environment and contemplate what the objects scattered throughout signify. Dr. Melissa Kägen, an assistant professor of interactive media and game development at Worcester Polytechnic Institute, refers to this type of interpretive gameplay in Walking Simulators as “archive adventure.”




Ready to play the role… Outer Wilds: Archaeologist’s Edition. Photo: Nintendo Switch

However, it’s not limited to Sims; there are various puzzle games where one can take on the role of an archaeologist, piecing together remnants of the past from archived materials and clues. While some may label these games as “Metroidvanias,” I have a personal affinity for them. Essentially, “information games” (a term coined by developer Tom Francis) require players to formulate theories based on available information and utilize those theories to gain further insights. Heaven’s Vault stands out with its core mechanic of deciphering ancient languages, while other information games like Return of the Obra Dinn, Her Story, and Outer Wilds (which even has a dedicated “archaeologist edition”) encourage players to excavate clues related to their environments and histories.

In my research, I aim to explore how modern gaming can be documented as meticulously as ancient artifacts. I’ve noticed numerous parallels in the gaming landscape. The methods players use to document their experiences—such as screenshots, mapping, and journaling—mirror techniques employed by real-world archaeologists. Some games integrate these documentation methods as central mechanics. A prime example is Season: A Letter to the Future, where players capture the world’s essence just before a cataclysm through their diary entries. Games that prompt note-taking certainly enhance the recording of gameplay experiences, such as the anticipated 2025 puzzle sensation, Blue Prince.

If you’re interested in becoming a video game archaeologist rather than just Tomb Raider-ing, look for the skull next to the toilet. Better yet, document your findings. Future gaming archaeologists will be grateful!

Console Wars… Indiana Jones and the Big Circle. Photo: Game Press

This week’s question comes from Richard B. via email.

“Does the console war still exist?”

This is a topic currently under scrutiny throughout the industry. In February, Xbox Chief Phil Spencer told Xboxera that he’s no longer focused on attracting players from PlayStation or PC. Just three months later, previously exclusive titles like Indiana Jones and the Big Circle have been announced for PS5, alongside Gears of War: Reloaded being linked to Sony’s platform. In return, Sony will release Helldivers 2 on Xbox, with more collaborations likely to follow. A recent Sony job listing suggests they are indeed open to this.

Cross Play—features available in games like Fortnite and Apex Legends—allows players across different systems to compete. In an industry where mobile gaming is increasingly dominant, with NewZoo projecting a worth of $92.5 billion for mobile games in 2024, the competitive landscape is changing.

Still, gamers are inherently territorial in nature. Brand loyalty remains a significant facet of fandom (think Nikon vs. Canon, Nike vs. Reebok, or Android vs. iPhone). Technical specifications are merely one aspect of these rivalries, with style, image, and identity also playing vital roles. Thus, don’t anticipate Xbox and PlayStation to transform into mere apps across various platforms anytime soon. Some battles may come to a close, yet the war rages on.

Federal Judge Rules Google Not Required to Sell Chrome

Google will not be compelled to divest its Chrome browsers. A federal judge ruled last year’s monopoly case in the ongoing legal dispute involving the tech giant.

The company is prohibited from specific monopolistic transactions with device manufacturers and is required to share data from search engines with competitors, according to the judge’s decision.

Judge Amit Mehta’s ruling comes after months of speculation regarding the penalties Google might face, following a judgment last year which found that Google violated antitrust laws, establishing what the company referred to as an online search monopoly. This case is considered one of the most significant antitrust proceedings in decades, resulting in further hearings in April to ascertain appropriate government actions for relief.

Mehta’s decision to let Google retain Chrome reflects a more favorable outcome for the company than what federal prosecutors had sought. The prosecution had proposed that Google divest its marquee search products and barred it from entering the browser market for a period of five years. In his extensive 230-page ruling, Mehta stated that the prosecutors had “overvalued by seeking mandatory sales of these key assets.”

While Google averted the most severe repercussions for antitrust violations, Mehta’s ruling supported prosecutors by forbidding the establishment or continuation of exclusive agreements regarding the distribution of products such as Chrome, Google Assistant, and Gemini apps. However, this ruling does not restrict Google from compensating distributors.

Following Mehta’s decision, Google’s shares experienced a rise in after-hours trading, indicating investor confidence in the favorable outcomes for the company.

The ruling was critiqued as “a complete failure” by the nonprofit advocacy group, the American Economic Freedom Project.

“It’s akin to finding someone who robbed a bank, only to tell him to write a thank-you note to the robber,” remarked Nidhi Hegde, the executive director of the American Economic Freedom Project. “Likewise, Google is not held accountable for monopolistic behavior, while a remedy is drafted to safeguard that monopoly.”

Google contended that under the Antimonopoly Act, which was first tried in 2023, its advantage in search is not a product of anticompetitive actions but stems from the creation of superior products.

Meanwhile, prosecutors have demonstrated that Google has invested billions in agreements with device manufacturers like Samsung and Apple to establish the browser as the default search for their products, allowing it to secure approximately 90% of the U.S. search market.

“After thorough deliberation and consideration of witness testimonies and evidence, the court concluded that Google was the monopoly and acted to preserve its monopoly,” Mehta ruled last year.

Mehta’s relief decision this week acknowledged that there have been significant transformations in the internet search industry since last year’s case concluded, indicating that his ruling was designed to address both popular search engines and the recent emergence of AI search engines and chatbots developed by Google.

“The procedures for these remedies were aimed at fostering competition among general search engines (GSEs) as much as ensuring that the advantages in search were not overshadowed by developments in the AI space,” Mehta stated.

Additionally, Google is set to face another hearing later this year regarding how the government will manage antitrust violations connected to its monopoly in online advertising technology.

Lawyers Disciplined for Using AI-Generated False Quotes in Australian Trial | Legal News

A Victorian lawyer has made history as the first in Australia to garner professional sanctions for utilizing artificial intelligence in court, losing his right to practice as a leading attorney after generating unverified citations from AI.

According to a report by Guardian Australia, during a hearing last October on July 19, 2024, an unnamed lawyer representing her husband in a marital dispute provided the court with a list of prior cases that Judge Amanda Humphreys had requested regarding the enforcement of applications in this case.

Upon returning to her chamber, Humphreys stated in her ruling that neither she nor her colleagues could find any cases listed. When the issue was revisited in court, the lawyer disclosed that the list had been generated using AI-based legal software.

He confessed to not verifying the accuracy of the information before submitting it to the court.

The attorney extended an “unconditional apology” to the court, requesting not to be referred for investigation, saying he would “integrate lessons that he has taken to heart.”

He acknowledged his lack of understanding of how the software operated and recognized the necessity to verify the accuracy of AI-assisted research. He agreed to cover the costs incurred by the opposing lawyer due to the canceled hearing.

Humphreys accepted the apology, admitting that the stress it caused was unlikely to be repeated. However, given the prevalence of AI tools in the legal field, she noted that referrals for investigation were crucial due to the role of the Victorian Legal Services Commission in examining professional conduct.

The lawyer was subsequently referred to the Victorian Legal Services Commission for investigation, marking one of the first reported cases in Australia involving a lawyer using AI in court to produce fabricated citations.

The Victoria Legal Services Board confirmed on Tuesday that the lawyer’s practice certificate was altered on August 19 due to the findings of the investigation. This action means he no longer has the right to practice as a primary attorney, cannot handle trust funds, and is restricted to working solely as an employee’s lawyer.

The lawyer is required to undergo two years of supervised legal practice, with quarterly reports to the board from both him and his supervisor during this period.

A spokesman remarked, “The board’s regulatory actions on this matter reflect our commitment to ensuring that legal professionals using AI in their practices do so responsibly and in alignment with their obligations.”

Since this incident, over 20 additional cases have been reported in Australian courts where litigants or self-represented individuals used artificial intelligence to prepare court documents, leading to the inclusion of false citations.

The lawyer in Western Australia is also under scrutiny by its state regulatory body regarding practice standards.

In Australia, there was at least one instance where a document was claimed to have been prepared using ChatGPT solely for the court, even though the document was generated before ChatGPT became publicly accessible.

The courts and legal associations acknowledge the role of AI in legal proceedings but continue to caution that this does not diminish lawyers’ professional judgment.

Juliana Warner of Australia’s Legal Council told Guardian Australia last month, “If lawyers are using these tools, it must be done with utmost care, always keeping in mind their professional and ethical obligations to the court and their clients.”

Warner further noted that while the court’s relation to cases involving AI-generated false citations raises “serious concerns,” a blanket ban on the use of generative AI in legal proceedings “is neither practical nor proportional and risks hindering access to both innovation and justice.”

The Ghost of Yotei: Vengeful Outsiders in Feudal Japan | Gaming

Atsu is not a Samurai. The protagonist of Ghost of Yōtei is a wandering sellsword from a humble background. Her absence of gender and status means that after her family’s murder, she has no secure position in 17th-century Japanese society and no options to seek revenge on the six Yotei, the man responsible for her loss. As Nate Fox, the game’s co-director, puts it, “Atsu is not the one who walks into a room; people are respectful.”

Yotei follows the legacy of Sucker Punch Productions’ 2020 expansive open-world game, Ghost of Tsushima, which narrates the tale of Jin Sakai, a samurai who embodies honor while defending his homeland. Jin is unable to fend off the Mongol invasion as a noble warrior, but as a “ghost,” he employs terrifying legendary tactics to gain the upper hand. While Tsushima’s ghost portrays someone maneuvering through varying types of power dynamics, Yōtei showcases Atsu harnessing the singular power achievable with both hands.




The pinnacle of achievement… Yotei’s ghost. Photo: Sony Interactive Entertainment

ATSU adopts the mantle of Onryō, a spirit of vengeance from Japanese folklore. By embracing this myth, she becomes a figure of terror to her adversaries. The gameplay is akin to Tsushima, yet in Yotei’s Ghost, players ride horses and navigate through a beautifully crafted open-world Japan, striking foes with the precise strokes of a katana.

“She leads a life distinctly different from Jin’s, and we aim to highlight that through interactivity,” Fox explains. This involves subtracting the contemplative moments present in Tsushima, where Jin takes time to meditate and transforms his struggles into haiku. “Jin was an intellectual samurai, pausing to appreciate the beauty of nature and weave it into his existence. Atsu is not that person.” These reflective moments soften the harsher aspects of Tsushima, traits that Fox and his team consciously avoided in Yotei’s vibrant landscape. Atsu is focused on collecting trophies while pursuing warriors across Hokkaido.

Sucker Punch highlights the contrasts between the main characters through a mobile campsite, a subtle advancement in the open-world genre. “We enjoy creating features that enhance the tone,” remarks Jason Connell, another game director at Yōtei. “Camping is a feature you can expect in a world like this,” Fox adds, “Atsu is a sellsword who has found a place to rest.”


As the game’s world expanded and the number of questlines and upgrade options grew, a management barrier emerged between players and the universe they were exploring. Instead of venturing on foot, fast travel is utilized between mapped markers. “That creates a disconnect,” asserts Connell. One moment you could be battling a mercenary in an exotic forest. Atsu’s camp aims to mend this discrepancy and reinforce player immersion. Quest givers, shopkeepers, and vital characters offer ways to engage and progress in the narrative without interrupting the story’s flow. “That’s beneficial,” Connell states.

In this fashion, Yōtei is poised to be both an evolution and a counterpart to Tsushima. Three hundred years after the original tale, on the opposite side of Japan, players will inhabit a world viewed through the sandals of characters from the lower echelons of society, creating a familiar yet intriguingly transformed landscape.

Ghost of Yōtei will be available on PlayStation 5 on October 2nd

I Felt It Was My Destiny: Social Media Rumors Sparked Pregnancy Speculation, Leading to Unforeseen Consequences

I cannot recall the exact moment my TikTok feed presented me with a video of a woman cradling her stillborn baby, but I do remember the wave of emotion that hit me. Initially, it resembled the joyous clips of mothers holding their newborns, all wrapped up and snug in blankets, with mothers weeping—just like many in those postnatal clips. However, the true nature of the video became clear when I glanced at the caption: her baby was born at just 23 weeks. I was at 22 weeks pregnant. A mere coincidence.

My social media algorithms seemed to know about my pregnancy even before my family, friends, or doctor did. Within a day, my feed transformed. On both Instagram and TikTok, videos emerged featuring women documenting their journeys as if they were conducting pregnancy tests. I began to “like,” “save,” and “share” these posts, feeding the algorithm and indicating my interest, and it responded with more content. But it didn’t take long for the initial joy to be overtaken by dread.

The algorithm quickly adapted to my deepest fears related to pregnancy, introducing clips about miscarriage stories. In them, women shared their heartbreaking experiences after being told their babies had no heartbeat. Soon, posts detailing complications and horror stories started flooding my feed.

One night, after watching a woman document her painful birthing experience with a stillbirth, I uninstalled the app amidst tears. But I reinstalled it shortly after; work commitments and social habits dictated I should. I attempted to block unwanted content, but my efforts were mostly futile.

On TikTok alone, over 300,000 videos are tagged with “miscarriage,” and another 260,000 are linked under related terms. A specific video titled “Live footage of me finding out I had a miscarriage” has garnered almost 500,000 views, while fewer than 5 million have been dedicated to women giving birth to stillborns.

Had I encountered such content before pregnancy, I might have viewed the widespread sharing of these experiences as essential. I don’t believe individuals sharing these deeply personal moments are in the wrong; for some, these narratives could offer solace. Yet, amid the endless stream of anxiety-inducing content, I couldn’t shake the discomfort of the algorithm prioritizing such overwhelming themes.

When discussing this experience with others who were also pregnant at the same time, I found shared nods of understanding and similar narratives. They too recounted their personalized concoctions of fears, as their algorithms zeroed in on their unique anxieties. Our experiences felt radical as we were bombarded with such harrowing content, expanding the range of what is deemed normal concern. This is what pregnancy and motherhood are like in 2025.

“Some posts are supportive, but others are extreme and troubling. I don’t want to relive that,” remarks 8-month-pregnant Cerel Mukoko. Mukoko primarily engages with this content on Facebook and Instagram but deleted TikTok after becoming overwhelmed. “My eldest son is 4 years old, and during my pregnancy, I stumbled upon upsetting posts. They hit closer to home, and it seems to be spiraling out of control.” She adds that the disturbing graphics in this content are growing increasingly hard to cope with.

As a 35-year-old woman of color, Mukoko noticed specific portrayals of pregnant Black women in this content. A 2024 analysis of NHS data indicated that Black women faced up to six times the rate of severe complications compared to their white counterparts during childbirth. “This wasn’t my direct experience, but it certainly raises questions about my treatment and makes me feel more vigilant during appointments,” she states.

“They truly instill fear in us,” she observes. “You start to wonder: ‘Could this happen to me? Am I part of that unfortunate statistic?’ Given the complications I’ve experienced during this pregnancy, those intrusive thoughts can be quite consuming.”

For Dr. Alice Ashcroft, a 29-year-old researcher and consultant analyzing the impacts of identity, gender, language, and technology, this phenomenon began when she was expecting. “Seeing my pregnancy announcement was difficult.”

This onslaught didn’t cease once she was pregnant. “By the end of my pregnancy, around 36 weeks, I was facing stressful scans. I began noticing links shared by my midwife. I was fully aware that the cookies I’d created (my digital footprint) influenced this feed, which swayed towards apocalyptic themes and severe issues. Now with a 6-month-old, her experience continues to haunt her.

The ability of these algorithms to hone in on our most intimate fears is both unsettling and cruel. “For years, I’ve been convinced that social media reads my mind,” says 36-year-old Jade Asha, who welcomed her second child in January. “For me, it was primarily about body image. I’d see posts of women who were still gym-ready during their 9th month, which made me feel inadequate.”

Navigating motherhood has brought its own set of anxieties for Asha. “My feed is filled with posts stating that breastfeeding is the only valid option, and the comment sections are overloaded with opinions presented as facts.”

Dr. Christina Inge, a Harvard researcher specializing in tech ethics, isn’t surprised by these experiences. “Social media platforms are designed for engagement, and fear is a powerful motivator,” she observes. “Once the algorithm identifies someone who is pregnant or might be, it begins testing content similar to how it handles any user data.”

“This content is not a glitch; it’s about engagement, and engagement equals revenue,” Inge continues. “Fear-based content keeps users hooked, creating a sense of urgency to continue watching, even when it’s distressing. Despite the growing psychological toll, these platforms profit.”

The negative impact of social media on pregnant women has been a subject of extensive research. A systematic review examining social media use during pregnancy highlights both benefits and challenges. While it offers peer guidance and support, it also concludes that “issues such as misinformation, anxiety, and excessive use persist.” Dr. Nida Aftab, an obstetrician and the review’s author, emphasizes the critical role healthcare professionals should play in guiding women towards healthier digital habits.

Pregnant women may not only be uniquely vulnerable social media consumers, but studies show they often spend significantly more time online. A research article published in midwife last year indicated a marked increase in social media use during pregnancy, particularly peaking around week 20. Moreover, 10.5% of participants reported experiencing symptoms of social media addiction, as defined by the Bergen Social Media Addiction Scale.

In the broader context, Inge proposes several improvements. A redesigned approach could push platforms to feature positive, evidence-based content in sensitive areas like pregnancy and health. Increased transparency regarding what users are viewing (with options to adjust their feeds) could help minimize harm while empowering policymakers to establish stronger safeguards around sensitive subjects.

“It’s imperative users understand that feeds are algorithmic constructs rather than accurate portrayals of reality,” Inge asserts. “Pregnancy and early parent-child interactions should enjoy protective digital spaces, but they are frequently monetized and treated as discrete data points.”

For Ashcroft, resolving this dilemma is complex. “A primary challenge is that technological advancements are outpacing legislative measures,” she notes. “We wander into murky waters regarding responsibility. Ultimately, it may fall to governments to accurately regulate social media information, but that could come off as heavy-handed. While some platforms incorporate fact-checking through AI, these measures aren’t foolproof and may carry inherent biases.” She suggests using the “I’m not interested in this” feature may be beneficial, even if imperfect. “My foremost advice is to reduce social media consumption,” she concludes.

My baby arrived at the start of the year, and I finally had a moment to breathe as she emerged healthy. However, that relief was brief. In the months following my transition into motherhood, my feed shifted yet again, introducing new fears. Each time I logged onto Instagram, the suggested reels displayed titles like: Another baby falls victim to danger, accompanied by the text “This is not safe.” Soon after, there was a clip featuring a toddler with a LEGO in their mouth and a caption reading, “This could happen to your child if you don’t know how to respond.”

Will this content ultimately make me a superior, well-informed parent? Some might argue yes. But at what cost? Recent online safety legislation emphasizes the necessity for social responsibility to protect vulnerable populations in their online journeys. Yet, as long as the ceaseless threat of misfortune, despair, and misinformation assails the screens of new and expecting mothers, social media firms will profit from perpetuating fear while we continue to falter.

Archaeologists Discover That Rivers and Tides Fueled the Rise of Ancient Schmer

The latest study presents paleoenvironmental models indicating how tidal dynamics played a crucial role in the early evolution of Sumerian agriculture and sociopolitical intricacies.

The earliest known network of city-states, intricately linked by common cultural practices and economic ties, emerged in southern Mesopotamia approximately 5,000 years ago.

The prosperity of this urban center, collectively referred to as Schmer, was fundamentally based on agriculture, supported by extensive irrigation systems.

The urbanization of Schmah, following the long-standing rural Ubaid culture, was part of a process that began at least prior to the millennium during the Uruk period (6,000-5,200 years ago).

The concurrent rise in population, innovation, and professional specialization during this time led to the formation of a state system with a complex economy, interlinking urban centers with their rural surroundings.

This “Sumerian takeoff” could not have happened in the challenging, arid tropical region between the Arabian and Iranian deserts without access to the perennial freshwater provided by the Euphrates and Tigris rivers.

However, questions remain about how, and when, labor-intensive large-scale irrigation became prevalent in the area, and how the abundance of water transformed into social prosperity.

“Our findings indicate that Sumer was literally built upon the rhythm of water, culturally,” states Dr. Lviv Giosan, a researcher at Woods Hole Marine Facilities.

“The cyclical tidal patterns and the morphodynamics of deltas—how landscapes evolve over time due to dynamic processes—were intricately woven into Sumerian mythology, innovation, and daily life.”

This research reveals that between 7,000 to 5,000 years ago, the Persian Gulf was expanding inland, with tides pushing freshwater into the lower Tigris and Euphrates twice daily.

Scholars propose that early communities harnessed this reliable hydrology through short canals to irrigate crops and cultivate dates, allowing for high-yield farming without the need for vast infrastructure.

As the river created a delta at the bay’s head, tidal access to the interior was obstructed.

The subsequent loss of tidal influence may have sparked ecological and economic crises, necessitating a significant social response.

The extensive efforts for irrigation and flood management that followed ultimately characterized Schmer’s golden age.

Dr. Reed Goodman, a researcher at Clemson University, remarked:

“The Mesopotamian delta was distinct. Its constantly shifting land spurred some of the earliest intensive agriculture in history and led to ambitious social experiments, driven by that restless land.”

In addition to environmental factors, this study also investigates the cultural impact of this aquatic foundation, linking Mesopotamia to the Sumerian pantheon’s flood myth.

“The key conclusions of this research highlight what we discovered in Ragash,” notes Dr. Holly Pittman, director of the Ragash Archaeology Project at the Penn Museum.

“Rapid environmental changes fueled inequality, political integration, and the ideology of the world’s first urban societies.”

Leveraging ancient environmental and landscape data, new samples from historic Ragash archaeological sites, and detailed satellite imagery, the authors reconstructed what Sumerian coasts may have looked like long ago and envisioned how its inhabitants adapted to their ever-changing environment.

“Our work underscores both the opportunities and risks associated with social transformation in response to significant environmental crises,” Dr. Giosan added.

“It is always fascinating to uncover genuine history hidden within mythology, and interdisciplinary research like ours plays a crucial role in revealing it.”

Hepatitis B Vaccination Linked to Reduced Diabetes Risk

Daily vaccinations for hepatitis B are administered worldwide

Mehmet Salih Guler / Getty Images

The hepatitis B vaccine not only prevents infection but also appears to lower the chances of developing diabetes.

In most countries, infants receive this vaccine routinely, typically as part of a three-dose series. In the US, it was incorporated into vaccination schedules in 1991. By 2018, around 30% of adults were fully vaccinated.

Researchers previously noted that vaccination may decrease diabetes risk. This is related to hepatitis B, which infects the liver and is transmitted through blood, semen, and vaginal fluids – impairing the liver’s ability to manage glucose. Elevated blood sugar levels can lead to diabetes.

However, earlier studies didn’t investigate whether vaccination could lower diabetes risk in individuals who were not infected with hepatitis B.

To address this gap, Nhu-Quynh Phan from Taipei Medical University in Taiwan and her team examined health data from over 580,000 people across the US, Europe, Africa, Latin America, the Middle East, and Asia-Pacific. These records averaged almost four years for each individual, covering the period from 2005 to 2023.

Participants aged 18 to 90 had no types of diabetes and were not infected with hepatitis B. About half were vaccinated, determined by measuring virus-specific antibodies in their blood.

The study revealed that diabetes prevalence among vaccinated individuals was 15% lower than in the unvaccinated group, with most cases being type 2 diabetes, the most prevalent form. The findings will be shared at the upcoming annual meeting of the Diabetes Association in Vienna, Austria.

This observational study also indicated a dose-response correlation. Participants with higher levels of hepatitis B-specific antibodies were less likely to develop diabetes compared to those with lower levels. Variations in antibody levels might correlate with the number of vaccinations received, timing of immunization, or individual immune responses.

No participants were purposefully infected with hepatitis B, suggesting that vaccination not only wards off the virus but may also lower diabetes risk, Fan notes. One explanation could be that vaccines help alleviate chronic inflammation damaging the liver and pancreas, which produce hormones like insulin regulate blood sugar levels.

Nonetheless, researchers cannot dismiss the theory that some protective benefits of vaccines might stem from their role in preventing infections, she adds. They are keen to investigate credible pathways and how mouse models can elucidate distinctions between diabetes types, Fan states.

Vaccinated individuals might also engage in healthier lifestyle choices, such as maintaining a nutritious diet and staying active. “Those likely to get vaccinated often exhibit greater awareness of health,” states Albert Osterhouse from the University of Veterinary Medicine in Hanover, Germany.

The research team considered factors including participants’ age, gender, and lifestyle choices like smoking, along with conditions such as obesity and hypertension. However, Osterhouse emphasizes the difficulty in ruling out the impact of these variables.

Introducing the Revenge Quitters: Why Workers are Walking Away and Refusing to Stay Silent

In 2011, Joey Lanev de Francesco spent nearly four years working in room service at a luxury hotel in Providence, Rhode Island, earning a mere $5.50 (£4) per hour. He endured long shifts that took a toll on him and reduced his hard-earned tips.

The inadequate treatment escalated when De Francesco and his coworkers attempted to unionize. The manager responded harshly, punishing employees for minor infractions. In fact, shift workers who needed to call guests were prohibited from sitting down.

De Francesco ultimately decided to resign. On his final day, he secretly entered the hotel staff quarters with a herd of seven powerful marching bands, surprising his boss with a musical farewell. “I’m here to tell you I’m not going,” he proclaimed, exiting while his band played triumphant tunes and chanted “Joey Quits.”

At 22 years old, De Francesco quickly enlisted friends to record the event. After sitting on the video for a few days, he uploaded it to YouTube, where it rapidly gained traction. Fast forward 13 years, and the video has garnered nearly 10 million views.

“We didn’t think it would gain much attention,” De Francesco, now 36 and living in New York, stated. The musician expressed feeling “liberated” after resigning and turning the tables on his manager. “Now, I’m ashamed of you for treating everyone so poorly,” he remarked.

Did his viral exit hinder his job prospects? Not at all. Shortly thereafter, De Francesco found work at a museum, noting that the incident “will never come up” in job interviews—perhaps even something worth adding to his resume.

De Francesco’s story remains iconic in the Hall of Fame of Resignation, but it faces stiff competition from a new wave of employees. More workers are staging revenge resignations, demonstrating their discontent with their workplaces. Even clergy members are partaking in this trend: In July, Father Pat Brennan delivered a “farewell gift” to his congregation in the form of a poem that doubled as his resignation letter, aiming to be an “uncomplaining, undesirable” parishioner who spread “gossip” using “holy lips.”

Employer review site Glassdoor warned at the end of last year about a “wave of revenge” shaping the future of employee satisfaction by 2025. A survey of 2,008 workers in the UK released in July revealed that 15% have left their jobs out of revenge. Social media has accelerated this trend, with many sharing their stories online. Brianna’s resignation video concluded with a rallying cry: “These companies will fire you in a day and leave nothing behind.

The 26-year-old American, living in Kyoto, Japan, was just two hours away from teaching his next English class when he quit. Initially, things were manageable, but it quickly changed. “If I finished a lesson a minute early or late, she’d become upset,” Slaughter recounted.

As Slaughter began to work, he found lots of free time, but his coworkers were mostly “cold,” and soon, problems began to arise. They earned 2,000 yen (£10) per class instead of hourly wages, forcing them to endure unpaid hours between classes for minimal compensation. Schedules were often given out just a day before, making planning nearly impossible. Due to the sedentary nature of the job, Slaughter developed health issues: “I went to the doctor, and they said, you’re sitting all the time, so you’re getting inflammation in your neck,” he noted.

Slaughter’s breaking point occurred with the arrival of a new manager, who insisted he wear long sleeves to cover his “aggressive tattoos” and often sat in on classes. It escalated to the point where Slaughter was crying every night. After receiving an unimpressive 100,000 yen (£500) for a month of “Hardcore Classroom Lessons” last May, he had had enough.

Slaughter sent his resignation letter into the digital ether before quickly recalling that a two-month notice was required. In a TikTok video that has amassed 1.2 million views, Slaughter addressed his manager:

Far from hindering their careers, these stories have gone viral, unlocking new opportunities. “I made $7,000 on TikTok in the month I left,” Slaughter remarked. Many reached out, expressing that his video inspired them to leave their toxic workplaces: “They said: I think I’ll quit my job too. This was my sign.” For those undecided, Slaughter advised:

Younger generations are more likely to execute revenge resignations. A report revealed that 26% of individuals aged 18-34 and 22% of those aged 35-44 in the UK have done so, compared to just 8% of people aged 45-54. In June, a survey by the Business Research Group found a 15% difference in this regard between younger and older workers in the United States.

Four years ago, 25-year-old Carly, residing in Alabama, was jobless. After contacting a temp agency, she was immediately offered a receptionist position based solely on her resume, with instructions to start the next day. “It might not have been the ideal job, but I was desperate, so I accepted,” she reflected.

The initial three months were “wonderful,” leading to a promotion as the HR pay manager, but things soon took a downturn. A new colleague aligned with the boss began to spread false rumors that Carly was an alcoholic due to her use of a lamp instead of overhead lights in her office. “I liked the ambiance,” she noted.

Carly was soon assigned additional duties as an accounts payable manager. “It was too much for a 21-year-old to handle alone,” she explained. The company briefly hired a man who was paid $10 more per hour than her to assist, but he was fired after mishandling payroll. Carly was forced to juggle both roles once more.

“I was perpetually stressed, distressed, and crying,” she admitted. The situation reached a boiling point during a management meeting when a colleague expected her to “flap frustration” in front of everyone. “It was an absurd request,” she remarked. “He essentially aimed to bully me publicly,” but Carly had different plans.

On the day of the meeting, Carly awoke early, went to the office, and scheduled an email to all managers conveying, “Let them know how messed up their business is,” she stated. It began cautiously: “I decided it was time to pursue a different path,” but quickly escalated. She bluntly labeled one manager as “literally a rock” and mentioned that her heavy workload caused “daily stress that often culminated in anxiety attacks and tearful nights.” She concluded with, “My laptop and keys are on my desk.”

After hitting send, her boss attempted to call; Carly didn’t answer. “I never heard from them again,” she recounted. Upon leaving the office for the last time, she felt euphoric: “I could have stripped my clothes off and raced home naked. All my anxiety and stress melted away,” she claimed.

She quickly secured another job, although she had some reservations about future interviews. “If they ask, I’ll be honest. If you treat me well, I won’t do this to you,” Carly assured.

While most are no longer engaging in dramatic revenge resignations, some new workers may be motivated to share their own experiences. Katie Ostler left her job after two years at a supermarket in Melbourne, Australia, where she began working at 16. “It was a very toxic, high-pressure environment with significant sales,” she explained.

Now 29 and living in Manchester, UK, Ostler wasn’t concerned about her boss knowing her name for the first six months. “It wasn’t ideal, but I kept my head down and did what was required,” she expressed.

As she approached 18, new job opportunities, particularly in bars, opened up. When the toxic supermarket experience pushed her to the edge, she had already submitted her resume to a local pub. One day, a customer angrily yelled at one of Ostler’s 15-year-old colleagues over a refund. Rather than support the young employee, the manager sided with the customer and also shouted. “I decided it was time to leave,” she remarked.

Not long after, she received a bar job offer and went to the supermarket to submit her resignation during the mandatory week’s notice. Attempting to give her letter to the supervisor, she was directed to hand it directly to the manager, who was supposedly in an interview. After following the supervisor’s instructions on location, Ostler seized the opportunity. She delivered the letter and announced her departure. The room fell silent, and the interviewees stared at her in confusion. “It took a lot of courage. I left before my manager could respond,” she said.

That wasn’t the last she would hear from him. She received a call on her way to begin her new job, instructing her not to finish her final week because she “didn’t want my toxic energy” around the team. “I remember thinking, did you look in the mirror?” she recalled. She had to return to the supermarket several times for groceries. “I avoided it when possible, but people recognized me and said hello. Unfortunately, no one cheered for me when I entered,” she said. Nonetheless, the resignation felt empowering: “I felt like a boss. It was a very powerful moment.”

Revolutionary Optical Fibers Could Enhance Communication Capabilities

In a departure from conventional solid glass cores, the innovative optical fibers now incorporate an air core encased in precisely crafted glass microstructures to guide light. This advancement boosts transmission speeds by 45%, enabling greater data transfer over longer distances before amplification is required.

Petrovich et al. We report microstructured optical waveguides with unprecedented transmission bandwidth and attenuation. Image credit: Gemini AI.

Optical fibers in telecommunications have typically relied on solid silica glass constructs, and despite extensive refinements, their signal loss remains a critical challenge.

This results in about half of the light traveling through the fiber being lost after approximately 20 km, necessitating the use of optical amplifiers for extended distance communication, such as intercontinental terrestrial and undersea connections.

Minimizing signal loss can be achieved within a limited spectrum of wavelengths. This has constrained the data capacity in optical communications over recent decades.

Francesco Poletti and his team from the University of Southampton developed a new type of fiber optic featuring a hollow air core surrounded by intricately designed thin silica rings to effectively guide light.

Laboratory tests revealed that these fibers exhibit an optical loss of 0.091 decibels per kilometer at the commonly utilized optical wavelengths in communications.

Consequently, optical signals with appropriate wavelengths can travel approximately 50% farther before needing amplification.

This configuration offers a broader transmission window (the range of wavelengths where light propagates with minimal signal loss and distortion) than previous fiber optic technologies.

While this novel optical fiber may demonstrate lower losses due to the use of larger air cores, further investigation is necessary to validate these findings.

“We anticipate that advancements in manufacturing, geometric consistency, and reduced levels of absorbent gases in the core will solidify these new fibers as essential wave guiding technologies,” Reservers remarked.

“This breakthrough could pave the way for the next major advancement in data communication.”

Their study will be published in the journal Nature Photonics.

Archaeologists Discover Indigo Dye Residues on 34,000-Year-Old Grinding Tool in Georgia

Researchers from CA ‘Foscari University have discovered Indigotin, a blue secondary compound also known as indigo, on a non-nanoparticle ground stone tool unearthed from the Zuziana Cave at the foot of the Caucasus in Georgia. Indigotin forms through reactions with atmospheric oxygen and natural glycoside precursors from leaves of the Isatis Tinctoria. This indicates that the plant was deliberately processed as far back as 34,000 years ago, despite its non-educational applications.



Five pebbles from Zugiana Cave, Georgia. Image credit: Longo et al., doi: 10.1371/journal.pone.0321262.

Modern humans first appeared in archaeological records approximately 300,000 years ago in Africa.

Much of the evidence regarding their cognitive and technical skills is derived from the limited existence of stone artifacts and the remains of animals, as these endure far longer in the archaeological record compared to plant materials.

As a result, Paleolithic narratives predominantly emphasize animal hunting and the production of stone tools.

The so-called “majority,” particularly plants that lack significant mentions, especially those increasingly shown to be utilized for food, cordage, weaving, and medicine, create incomplete accounts.

This underscores the need to identify and illustrate the roles of plants in an array of activities, many of which may still be undiscovered.

“It’s not solely about viewing plants as food resources; that’s common. We emphasize their involvement in complex processes. It possibly involves transforming perishable materials for use at various stages of Homo sapiens 34,000 years ago.”

“While the identification of elusive plant residues not typically highlighted in traditional research continually improves, our multi-analytical approach unveils fresh perspectives on the technical and cultural sophistication of Upper Paleolithic tools, designed to skillfully exploit the vast resources of plants and fully acknowledge their significance.”

In their investigation, researchers examined stone tools dating back 34,000 years, discovered in Zugiana Cave, Georgia.

They identified signs of mechanical processing of soft, wet materials consistent with plant matter such as leaves.

Employing an array of microscopic techniques (both optical and confocal), blue residues (occasionally fibrous) alongside starch grains were unexpectedly revealed.

These residues were particularly prevalent in the areas of the tools that displayed significant wear.

To ascertain the blue residues’ nature, scientists used advanced microscopy techniques, specifically Raman and FTIR spectroscopy.

These analyses confirmed the existence of indigotin chromophores in several samples.

“Once the molecules responsible for the blue coloration were identified, new questions arose. How and why were these residues associated with the tool’s working surface?” the author remarked.

They subsequently investigated the porosity of the stone, a crucial factor for trapping and retaining biological residues.

Both microscopic fragments of the archaeological tool and larger samples of experimental replicas underwent analysis using Micro-CT tomography.

This analysis confirmed the presence of pores capable of holding trace biological remnants.

Consequently, the team devised a series of replication experiments.

Initially, raw rock materials resembling those used by prehistoric inhabitants of Zuziana were sourced.

The pebbles were collected by Nino Jakeli from the Nikrisi River, located just beneath the cave.

Following this, controlled experiments were conducted, mechanically treating a range of plants, including fiber sources (such as bast fiber) and potentially indigotin-yielding species.

“We employed a rigorous approach to pollution control and biomolecular analysis to provide insights into contemporary human behaviors and the technical and ecological knowledge likely prioritized during the Upper Paleolithic era,” the researchers stated.

“Whether this plant remains serve medicinal purposes or have other uses presents a new perspective on the intriguing potential for diverse plant utilization.”

Survey results have been published online in the journal PLOS 1.

New Research Uncovers the Secrets of Burgess Shale Trilobites

Appendages of arthropods serve various functions, including feeding, locomotion, and reproduction. Fossils dating back to the Cambrian period (539-487 million years ago) provide remarkable details of extinct arthropod appendages, enhancing our understanding of their anatomy and ecological roles. However, due to the limited number of fossils and often incomplete preservation, studies on appendage functions typically depend on idealized reconstructions. This new research focuses on the paleontological species Olenoides serratus, a prolific trilobite from the Cambrian Burgess Shale, noteworthy for its numerous well-preserved specimens featuring soft tissue that allow for a detailed analysis of appendage functionality.

Situated in British Columbia, Canada, the Burgess Shale is renowned for its exceptional fossil preservation, including soft tissues such as limbs and internal organs.

While trilobites are common in fossil records, their soft limbs are seldom preserved due to their hard exoskeleton, leading to a limited understanding of these structures.

The trilobite species Olenoides serratus offers a unique chance to investigate these appendages further.

Harvard paleontologist Sarah Ross and her team examined 156 limbs from 28 fossil specimens of Olenoides serratus to reconstruct the precise movements and functions of these ancient arthropod appendages, shedding light on one of the earliest successful aquatic animals.

“Understanding the behavior and movement of fossils poses challenges, as we cannot observe their activities like we do with living organisms,” stated Dr. Ross.

“Instead, we meticulously analyzed the morphology of numerous specimens while also utilizing modern analogues to infer how these ancient creatures lived.”

The researchers also assessed the range of motion of the legs of living horseshoe crab species Limulus polyphemus.

“Arthropods possess articulated legs composed of multiple segments that can flex upwards or downwards,” they noted.

“The range of motion is influenced by the specific directional capabilities of each joint.”

“This range, combined with the limbs’ shape and segment configuration, determines how the animal utilizes its appendages for walking, grasping, and burrowing.”

Horseshoe crabs, commonly found along the eastern coast of North America, are compared with trilobites due to their analogous behaviors.

“Despite their close relation to spiders and scorpions, horseshoe crabs are part of a different branch of the arthropod tree, whereas trilobite relationships remain ambiguous.”

The comparison arises from both animals’ adaptation of articulated limbs for navigating the seafloor.

However, the findings revealed that their similarities were minimal.

In contrast to horseshoe crabs, characterized by specialized limb joints for bending and expanding—facilitating feeding and protection—Olenoides serratus exhibited a simpler yet highly functional limb structure.

“We found that the limbs of Olenoides serratus had minimal extension, primarily far from the body,” Dr. Ross explained.

“Their limbs functioned differently than those of horseshoe crabs. Olenoides serratus could walk, dig, bring food to their mouths, and even elevate their bodies above the seafloor.”

To realize these findings, the scientists constructed advanced 3D digital models based on hundreds of fossil images captured from various angles.

Since trilobite limbs are often crushed and flattened, reconstructing them in three dimensions presents a significant challenge.

“We depend on exceptionally well-preserved specimens, comparing limb structures from multiple angles while leveraging related fossils to fill in any missing details,” said Professor Javier Ortega-Hernandez of Harvard University.

The team correlated the morphology of trace fossils to the movements of the limbs.

“The different movements of Olenoides serratus could create trace fossils with varying depths,” Dr. Ross elaborated.

“They were capable of raising their bodies on deposits, allowing them to traverse obstacles and navigate efficiently through swift currents.”

Remarkably, the researchers found that males possessed specialized appendages for mating, and each leg featured gills for respiration.

The findings were published in the journal BMC Biology on August 4th, 2025.

1,600 Years of Samaritan Reconciliation Discovered in Israel

Archaeologists from the Israeli Ancient Bureau (IAA) have discovered historical agricultural archaeological sites at the KH site, located in Kahru Chatta of central Israel.

“The grandeur of the discovered structures, the exquisite quality of the mosaic floors, and the remarkable agricultural facilities indicate the significant wealth and prosperity of the local Samaritan community over time.”

“The Kh. KafrHatta site is noted as the birthplace of Menander, the Samaritan magician, a precursor to the Gnostics and a successor to Simon Magus, regarded as one of the first converts to Christianity.”

In one of the structures, archaeologists uncovered a stunning mosaic floor adorned with intricate geometric patterns and representations of plants.

“Alongside the central medallion, the acanthus leaves are interwoven with distinctive motifs of fruits and vegetables, including grapes, dates, watermelons, artichokes, and asparagus,” they noted.

“At the doorway of this room, a partially preserved Greek inscription wishes good fortune to the building’s owner!”

“The name of the owner was prevalent in the Samaritan community.”

https://www.youtube.com/watch?v=wmrz8wqpfe0

In the northern area of the estate, researchers discovered olive presses, large storage buildings, and Mikube (public bathing facilities).

“The close proximity of the oil press to Mikube likely facilitated the production of high-quality olive oil,” they mentioned.

“The olive press was meticulously designed, comprising two wings.”

“The Northern Wing featured a major production area, while the Southern Wing included auxiliary facilities.”

“Within the production area, two screw presses and a large basin for crushed olives were found.”

“This type of olive press is more characteristic of the Jerusalem region and the Jewish Shephela, making it less common in Samaria,” explained Dr. Nagorsky.

“Over the years, the estate has experienced significant transformations.”

“The opulence and grandeur of the structures have been supplanted by oil production and agricultural infrastructure.”

“New walls damaged the mosaic floors, incorporating grand capitals and pillars into the updated structures.”

The team suggests these changes are connected to the Samaritan uprisings during Byzantine rule, which occurred in the 5th and 6th centuries, against Byzantine emperors who enforced restrictive laws on non-Christian communities.

“What makes this site particularly fascinating is that, unlike other Samaritan locations that were destroyed during these rebellions, the Kahru Kasim estate has continued to be used, preserving the Samaritan identity.

“It is a captivating site that illustrates the historical contrast between the era of prosperity and the decline of the Samaritan community,” remarked Dr. Nagorsky.

“Its longevity and remarkable findings enable us to reconstruct its history across centuries, enhancing our understanding of this ancient population.”

Rapamycin May Extend Lifespan by Safeguarding Against DNA Damage

Illustration of rapamycin (red), a drug that inhibits proteins known as MTOR (blue)

Science Photo Library/Alamy

The anti-aging benefits of rapamycin may be related, at least in part, to its ability to prevent DNA damage in immune cells.

Initially created as an immunosuppressant for organ transplant patients, rapamycin blocks the function of the MTOR protein, which is crucial for cell growth and division. Studies suggest that low doses can extend the lifespan of various organisms, including the mouse, potentially by disrupting processes associated with aging, such as inflammation, intracellular breakdown, and decline in mitochondrial function.

Recent research by Lynn Cox and colleagues at Oxford University has demonstrated that rapamycin also appears to prevent DNA damage in certain types of immune cells. DNA damage is one of the key factors contributing to aging in our immune system, accelerating the aging process throughout the body.

The researchers conducted experiments with human T cells, a type of white blood cell responsible for fighting infections. When T cells were exposed to an antibiotic named zeocin alongside rapamycin, significant DNA damage occurred.

Results showed that rapamycin lowered DNA damage and tripled cell survival rates compared to T cells exposed to zeocin alone.

The researchers found no indication that the observed effects were due to other actions of rapamycin, such as preventing cell failure. “We consistently observe this effect regardless of whether rapamycin is administered prior to, during, or post-injury,” noted team member Ghada Arsare at Oxford University.

The rapid response suggests a direct impact. “The effect is very swift, indicating it influences the DNA damage response and accumulation. The lesions observed last about four hours, so it’s unlikely that there are downstream effects impacting other processes,” explained Cox.

According to Matt Kaeberlein from Washington University in Seattle, the findings support the notion that rapamycin can directly protect DNA, but “this is not the critical mechanism.” Researchers aim to explore rapamycin-induced alterations in RNA and proteins produced in immune cells.

In a separate part of the study, nine men aged 50 to 80 were assigned to receive either 1 milligram of rapamycin or a placebo daily. Blood tests conducted eight weeks later revealed that T cells from men taking rapamycin exhibited less DNA damage. Furthermore, neither group experienced a decrease in overall white blood cell counts, indicating that rapamycin does not negatively impact immune functionality. “Our findings confirm that low doses are safe, which is crucial,” stated Cox.

Mitigating DNA damage in the immune system may provide a pathway for reducing overall aging, according to Cox. Arsare highlighted the potential for rapamycin to be used preventively, such as for astronauts exposed to cosmic radiation.

“Rapamycin is particularly promising in addressing aging-related issues where DNA damage is a significant factor, such as skin aging,” noted Kaeberlein. Referring to a study, he added that local use of rapamycin reduces aging markers in human skin. However, he cautioned against generalizing results to other types of damage, such as radiation, given that Cox’s team used antibiotics to create DNA damage.

Zahida Sultanova from the University of East Anglia emphasized the necessity for trials involving women and individuals across various age groups, as the placebo-controlled experiments were limited to older men. Evidence from non-human animal studies indicates that rapamycin may have sex-specific and age-specific effects.

Study Suggests Common Nasal Antihistamine Sprays Could Help Prevent Community Infections

Nasal sprays available over-the-counter, historically noted for their safety and efficacy in treating seasonal allergies, could be perceived in a new light following clinical trial results released on Tuesday.

The antihistamine azelastine has been observed to have antiviral properties against various respiratory infections, including Influenza, RSV, and viruses responsible for COVID, according to a growing body of research.

Researchers from Saarland University Hospital in Germany conducted a study involving 450 adults, predominantly in their early 30s. One group of 227 participants used a nasal spray three times daily, while the other 223 received a placebo spray under the same regimen.

Throughout nearly two months, all participants underwent COVID rapid testing twice weekly. The results indicated that the incidence of symptomatic infections was 2.2% in the azelastine group, markedly lower than the 6.7% infection rate in the placebo group.

Furthermore, azelastine seemed to diminish the incidence of other symptomatic respiratory infections, as highlighted in a study published in JAMA Internal Medicine.

While researchers remain uncertain about the exact mechanism by which azelastine limits infections, they hypothesize that it may bind to the virus in the nasal mucosa.

Another possibility is that azelastine interacts with the ACE2 receptor, the primary entry point for COVID viruses into human cells, thereby preventing their attachment.

“Our findings imply that azelastine could serve as a scalable and commercially viable preventive measure against COVID, especially in high-risk scenarios such as crowded indoor events and travel,” the researchers noted.

However, the study had limitations, including that all participants were relatively young and healthy, according to the researchers.

Valz emphasized that azelastine should not replace vaccination and further research is essential before considering it as a standard precautionary measure for the public, particularly for vulnerable groups.

Dr. William Messer, associate professor at Oregon Health & Science University, found the results “rationally convincing” in terms of risk reduction, but pointed out the intensive regimen of daily sprays in the trial.

He questioned whether wearing a mask might be a simpler approach to preventing COVID infection.

“Masks can be inconvenient and bothersome, yet may be easier to adhere to than remembering to use three nasal sprays daily,” Messer remarked.

Nevertheless, he added, “I do not discourage anyone who wishes to try it.”

Other researchers are seeking more data to ascertain the effectiveness of nasal sprays in high-risk populations, such as the elderly and immunocompromised individuals who require additional preventive measures.

Dr. Peter Chin-Hong, a professor at UCSF Health specializing in Infectious Diseases, speculated that azelastine could serve as an additional COVID-blocking tool for individuals already using nasal sprays for seasonal allergies, although he believes the evidence is insufficient for broader recommendations.

“While the potential is promising, I believe now is not the appropriate time to recommend it as a COVID preventative,” he stated in an email. “For those over 65, I continue to advocate for vaccination as the primary defense against COVID.”

Nonetheless, Chin-Hong highlighted that the trial results underscore the importance of targeting the nasal mucosa in developing future vaccines against COVID and other respiratory viruses as a more effective means of infection prevention.

“Current COVID vaccines have not proven to be highly effective in preventing infection,” he remarked. “There is a need for more mucosal vaccines for respiratory viruses. While flu vaccines are widely used, ongoing efforts are being made to create mucosal vaccines for coronaviruses, necessitating continued advocacy for federal support and prioritization for these initiatives.”

Can Every Metal Be Recycled from a Scrap Car?

Scrap vehicles are composed of various metal alloys, posing recycling challenges.

Innovative recycling methods for metals extracted from scrap cars can potentially eliminate millions of tons of waste annually while decreasing carbon emissions associated with the production of new aluminum.

Historically, a significant portion of scrap aluminum from cars has been repurposed into lower-grade cast alloys for engine blocks in traditional combustion engines. Yet, as the auto industry shifts towards electric vehicles, this low-grade metal no longer has utility.

Without effective strategies, there is a risk of generating millions of additional tons of carbon dioxide by accumulating “mountains” of unusable scrap and increasing the production of virgin aluminum for new vehicle manufacturing, warns Stephen Pogatcher from Leven University in Austria.

“As engine blocks become obsolete with electrification, we lack current paths for scrap utilization,” he cautions. “This constrains our recycling capabilities.”

Pogatscher and his team have developed a novel approach for recycling metals from scrap vehicles, which could convert approximately 7-9 million tons of waste annually into high-quality aluminum alloys suitable for various components of new cars.

The key lies in generating new products by harnessing a variety of alloy materials sourced from scrap vehicles, he elaborates.

Typically, when a car is discarded, its materials—plastic, fabric, steel, and aluminum—are processed separately. Moreover, as many as 40 different aluminum alloys are extracted from each vehicle across various recycling streams. Any non-separable components tend to blend into the engine block, associated with combustion engines.

The innovative recycling method pioneered by Pogatscher’s team involves melting all the scrap aluminum from the car simultaneously.

This results in a block of highly brittle material that resembles a metal ceramic, according to Pogatscher. Interestingly, the team found that reheating this block at approximately 500°C for 24 hours can restructure the metal, enhancing its strength and toughness. “Ultimately, it offers improved mechanical properties compared to conventional alloys,” he notes.

The team asserts that this new material rivals traditional automotive alloys, featuring “impressive” strength and versatility for fabricating various car components, including chassis and frames. Pogatscher emphasizes that it can be produced using standard industrial practices and has the potential for rapid scalability. While he recognizes the challenges in mainstream adoption of new alloys within the conservative manufacturing sector, discussions with industry partners regarding process development are already underway.

Jeffrey Scamans at Brunel University in London finds the concept “very intriguing,” but he stresses that further validation is essential, particularly to ensure the new alloy meets the stringent testing requirements for automotive applications.

He also cautions that achieving consistent high-quality alloys may be difficult since vehicles are discarded in a varied manner, not according to specific types. “It’s challenging to envision how to collect individual alloy compositions practically,” he remarks. “Scaling from laboratory experiments to full-scale metal production is notoriously complex.”

Mark Schlesinger at the Missouri University of Science and Technology states that commercial production must delineate and manage the composition of the new alloy. “Randomly mixing scrap in the furnace won’t yield acceptable results,” he says. “This necessitates precise scrap chemistry assessments, which subsequently raises handling costs.”

The Ubiquity of Steroids on Social Media: Understanding the Risks

If you’ve recently browsed fitness content on platforms like Instagram, Facebook, or TikTok, you might have encountered influencers who have used steroids. A recent global meta-analysis suggests that steroid usage among gym-goers varies from 6% to a shocking 29% across different countries.

This statistic might come as a shock. According to Timothy Piatkovski from Griffith University, the landscape of steroid use has evolved over the last decade. Many fitness influencers now present themselves as knowledgeable figures, openly discussing their drug use and advising followers on steroid usage.

“Regrettably, the level of medical knowledge and judgment varies significantly among these influencers,” states Piatkowski.

Influencers’ perceptions of health risks differ greatly, he observes. While some acknowledge the dangers of steroid use, asserting that risks can be managed sensibly, others are more reckless, promoting drugs like trenbolone, which is typically used to prevent muscle wastage in livestock, branding themselves as “Trenfluencers.”

Millions may question whether these substances are actually safe, or if influencers are leading them into perilous situations. What is the truth regarding the dangers associated with steroids? Is there a safer way to use them?

Piatkowski notes that research on the long-term health consequences of steroids is sparse. This is largely due to the mismatch between doses and usage patterns studied by researchers and those employed by actual users. He and his colleagues seek to bridge this gap by collaborating closely with steroid users to create more relevant and realistic studies.

However, this mismatch has already led to some influencers losing faith in mainstream scientific and medical perspectives, prompting users to seek advice from fitness and bodybuilding forums instead. These social media channels have become a major contributor to both the support network and the marketplace in the surge of steroid usage.

Users now have quick access to a range of substances that can be obtained illicitly. This includes oral anabolic steroids known as SARMs (selective androgen receptor modulators) and synthetic human growth hormone, naturally produced by the pituitary gland during adolescence. Collectively, they improve physique and performance, but their mechanisms can vary significantly.

One of the most prevalent substances is anabolic steroids, potent synthetic derivatives of testosterone. A 2022 study estimated that around half a million men and boys in the UK used them for non-medical purposes in the previous year.

Understanding Steroids

To determine whether steroids are safe, one must first grasp their effects on the body. Anabolic androgen steroids work by interacting with hormonal receptors that promote male sexual traits, particularly in muscle and bone tissues. “They aid in muscle growth and are vital for bone development; they guide boys through puberty and literally transform them into men,” explains Channa Jayasena from Imperial College London.

The desired result is evident: a bigger, stronger physique in a shorter timeframe. Medically, some of these substances are prescribed to treat conditions like muscle wasting associated with HIV. At lower doses, investigations suggest that steroids can be well tolerated. However, this is not a strategy commonly employed outside clinical settings.

Non-medical steroid use rarely mimics regulated clinical trials. Many users resort to “stacking” various drugs and alternate between cycles to allow bodily recovery, adopting practices like the “blast and cruise” regimen. Although these methods lack comprehensive scientific scrutiny, influencers often tout them as ways to minimize health risks or achieve effective muscle growth. This could explain why many users turn to influencers and online forums instead of healthcare professionals for advice.

The Risks of Unregulated Use

The temptation to test various drug combinations or follow cycling protocols stems from the belief that such strategies mitigate the adverse effects of anabolic steroids. The best-documented side effect is cardiovascular complications. Anabolic steroids are known to lower levels of high-density lipoproteins, or “good” cholesterol, while raising blood pressure and increasing low-density lipoproteins, known as “bad” cholesterol. This can thicken the heart muscle, potentially leading to cardiomyopathy—severe heart dysfunction and a lethal condition, as noted by Jayasena.

A Danish population study revealed that anabolic steroid users were three times more likely to die than other males during the study’s duration. “It’s akin to cocaine,” asserts Jayasena. Cardiovascular disease and cancer emerged as the most prevalent natural causes of death among these individuals.

Beyond cardiovascular matters, Jayasena highlights that the psychosocial implications of steroid use are significant and well-documented. The term “Roid Rage” encompasses various mental issues including aggression, mania, and mental illness—particularly among individuals consuming high doses. “When observing why steroid users have fatal outcomes, one notes three primary causes: cardiomyopathy, suicide, and aggression,” he notes, suggesting a possible correlation between steroid use and heightened tendencies toward criminal behavior.

This relationship remains contentious, as it’s challenging to differentiate the effects of steroid use from other contributing factors like recreational drug usage or pre-existing mental health issues. Nonetheless, it indicates that discontinuing steroid use may precipitate depression and suicidal thoughts. “The mind becomes lethargic,” explains Jayasena. “The recovery period can extend over months, sometimes even years.”

Research led by Jayasena revealed that nearly 30% of men who ceased steroid use experienced suicidal thoughts and major depression, possibly due to lingering steroid residues in brain areas responsible for emotional regulation. Additional studies indicate that steroids can impair kidney function and elevate cancer risks, although the data is less conclusive and heavily reliant on isolated medical case reports.

Several investigations have demonstrated that some of these health concerns might be reversible. For instance, the liver appears adept at self-repair and can manage lower clinical doses of certain steroids. Conversely, effects like high cholesterol and hypertension can be reversible post-steroid cessation; in contrast, others may require long-term or costly interventions to address, such as mood disorders and infertility.

The most severe repercussions of steroid use tend to be the hardest to treat. Structural alterations in the heart, along with research indicating lasting blood flow impairments to vital organs, is a concern that may linger long after users cease taking steroids.

Seeking “Safer” Steroids

Given the extensive and complex list of potential harms, many users experiment with steroid protocols aimed at risk reduction. This includes altering doses, timing, or combining them with other substances. However, there is a dearth of research examining the safety of these “protocols,” asserts Piatkowski.

One of Jayasena’s studies indicated that post-cycle therapy, where users take medications to restore natural testosterone production following steroid cycles, significantly lowered the risk of suicidal thoughts. Piatkowski’s research compares high-dose cycles and gradual tapering, identifying that those following a Blast Cruise approach reported fewer adverse health effects once they stopped using.

High-quality, controlled studies evaluating the effects of recreational steroid use are sparse, often characterized by small sample sizes or case reports that complicate the establishment of causal relationships. The evidence supporting specific protocols is also thin, particularly as patterns of steroid use evolve more rapidly than researchers can track.

Anabolic steroids are commonly injected into the subcutaneous fat layer located between the skin and muscle.

“Further longitudinal and cohort studies are essential,” Piatkowski asserts. Such studies track individuals’ health and wellbeing over time, ultimately clarifying real risks and potentially providing strategies for risk mitigation. Nevertheless, in the absence of robust evidence, healthcare providers often struggle to offer guidance to steroid users.

Greg James, a clinician at Kratos Medical in Cardiff, UK, mentions that he provides private health and blood testing services. Some patients even inquire about combining steroids with GLP-1 drugs that suppress appetite, as well as other peptides that regulate hunger. “They ask me if these peptides are safe,” James notes. “And I respond that I cannot confirm their safety due to the lack of long-term data.”

Researchers like Piatkowski are beginning to directly engage with users in realistic settings, navigating the challenges posed by inadequate clinical data and rapidly changing user behaviors. Rather than viewing users as patients or outliers, this method considers them as valuable sources of real-life experience, contributing to the development of more relevant and realistic research.

A recent study conducted by Piatkowski and collaborators examined steroid samples from users, revealing that over 20% were contaminated with toxic substances such as lead, arsenic, and mercury. More than half were incorrectly administered, meaning users may have been taking far more potent agents intended for livestock use.

Another study involving interviews with diverse steroid users identified trenbolone as having the most negative consequences, particularly for psychological and social health. This suggests that focusing on trenbolone as a distinct harmful substance, along with targeted screening and intervention strategies, could be more effective for harm reduction compared to broad-ranging methods.

Fitness influencers are frequently regarded as authorities who provide guidance on anabolic steroid use to their followers.

This open and collaborative methodology in drug research mirrors approaches seen in other recreational drug strategies, like psychedelic research. By engaging with real users, insight can be gained not only into harm reduction techniques but also previously unrecognized medicinal applications.

They may also collaborate with influencers and users to promote safer behaviors, rather than outright condemning drug usage, Piatkowski emphasizes. “Enhancing knowledge within these communities and legalizing information is crucial. It’s an ongoing experimental endeavor. The more we stimulate this discussion, the more we can advance the field.”
