Google Faces Déjà Vu as Second Exclusive Exam Launches in the U.S.

After successfully countering the US Department of Justice’s challenge regarding illegal monopoly in online searches, Google now faces another threat to its internet dominance in a trial centered around potentially abusive digital advertising practices.

This trial, which commenced on Monday in Alexandria, Virginia, focuses on the detrimental ruling by US District Judge Leonie Brinkema in April, who deemed certain aspects of Google’s digital advertising technology as an illegal monopoly. The judge concluded that Google’s actions were reducing competition and harming online publishers who depend on this system for revenue.

Over the next two weeks, Google and the Justice Department will present evidence in court and seek rulings on how to restore competitive market conditions, in what is being referred to as a “relief” trial according to Judge Brinkema.


As the Justice Department progresses, Brinkema has instructed Google to divest parts of its advertising technology. Google’s legal team argues that this could lead to “confusion and damage” to consumers and the overall internet ecosystem. However, the Justice Department contends that this is the most efficient and immediate approach to dismantling monopolies that have stifled competition and innovation for years.

“The goal of the relief is to take necessary steps to restore competition,” stated Julia Tarver Wood from the DOJ’s antitrust division during the opening remarks.

Wood accused Google of manipulating the market in a manner that conflicts with the principles of free competition.

“The means of fraud are hidden within computer code and algorithms,” Wood remarked.

In response, Google’s attorney Karen Dunn argued that the proposed government intervention was unreasonable and extreme, asserting that the DOJ aimed to eliminate Google from the competitive landscape entirely.

The Justice Department is “advocating for a solution that addresses a past overshadowed by technological advances and market shifts in digital advertising consumption,” Google’s attorneys contended during the trial.

Regardless of the judges’ verdict, Google plans to appeal any earlier decisions labeling its advertising networks as a monopoly, although an appeal can only proceed once a remedy is established.

This case was initiated under the Biden administration in 2023 and threatens the intricate network that Google has built over the last 17 years to bolster its dominant position in the digital advertising sector. Digital ad sales contribute significantly to the $350 billion revenue generated by Google’s services division for its parent company, Alphabet Inc.

Google asserts that it has made considerable adjustments to its “advertising manager” system, including more transparency and options for pricing, to address concerns highlighted in the judge’s ruling.

From the Frying Pan into the Fire

Google’s legal struggle regarding its advertising technology signifies another confrontation, following a recent case in which a federal judge condemned the major search engine as an illegal monopoly, leading to Remedy Hearings earlier this year aimed at combatting fraud.

In that scenario, the Justice Department suggested a strict enforcement measure that would mandate Google to sell its widely-used Chrome browser. However, US District Judge Amit Mehta opted for a more measured approach in a recent ruling that reshaped the search market, which is undergoing changes driven by artificial intelligence technology.


Google opposed all aspects of Mehta’s ruling, yet the outcome was generally perceived as a mere slap on the wrist. This sentiment contributed to a surge in Alphabet’s stock price, yielding a 20% increase since Mehta’s decision, elevating the company’s market valuation to over $3 trillion, making it one of only four publicly traded companies to achieve such a milestone.

With indications that the results of the Search Monopoly case could significantly impact advertising technology practices, Judge Brinkema has instructed both Google and the Department of Justice to incorporate Mehta’s decision into their arguments in forthcoming trials.

As seen in previous search cases, Google’s legal representatives have already asserted in court documents that the AI technologies applied by competitors in ad networks, like those operated by Meta, have transformed market dynamics, making a “radical” approach proposed by the Justice Department unnecessary.

Amazon Faces Legal Challenges in the US Over Claims of Subscription Cancellation Difficulties

Amazon faced a US government lawsuit on Monday, where it was accused of employing deceptive methods to enroll millions in its Prime subscription service, making cancellation nearly impossible.

A complaint from the Federal Trade Commission (FTC), filed in June 2023, alleges that Amazon deliberately used a “dark pattern” design to mislead consumers into subscribing to a $139 Prime service during checkout.

According to the complaint, “For years, Amazon has intentionally and subconsciously enrolled millions of consumers in the Amazon Prime service.”

The case pivots on two primary claims: that Amazon registered customers without their clear consent through a confusing checkout process, and that it established a convoluted cancellation system dubbed “Illid.”

Judge John Chun presided over the case in federal court in Seattle. He is also overseeing another FTC case accusing Amazon of operating an illegal monopoly.

This lawsuit is part of a broader initiative, with multiple lawsuits against major tech companies in a bipartisan bid to rein in the influence of US tech giants after years of governmental inaction.

Allegedly, Amazon was aware of the extensive non-consensual Prime registrations but resisted modifications that would lessen these sign-ups due to their adverse effect on company revenue.

The FTC claims that Amazon’s checkout process forced customers to navigate a confusing interface designed with prominent buttons, effectively hiding the option to decline while signing up. Crucial information regarding Prime pricing and automatic updates was often concealed or presented in fine print, forming a core part of Amazon’s business model.

Additionally, the lawsuit scrutinizes Amazon’s cancellation procedure, which the FTC describes as a complicated “maze” involving 4 pages and 6 clicks.

The FTC seeks financial penalties, monetary relief, and permanent injunctions to mandate changes in Amazon’s practices.

In its defense, Amazon argues that the FTC is overreaching its legal boundaries and asserts that it has made improvements to its registration and cancellation processes, dismissing the allegations as outdated.

The trial is anticipated to last around four weeks, relying heavily on internal Amazon communications and documents, as well as testimonies from company executives and expert witnesses.

Should the FTC prevail, Amazon could face significant financial repercussions and may be required to reform its subscription practices under court supervision.

Murdoch, Ellison, and China: Insights into the U.S. TikTok Trade | Technology

For a week now, the White House has indicated that a deal is on the horizon to transfer TikTok’s ownership to an American company. Donald Trump is set to sign an executive order this week that will establish a framework for a consortium of investors to take over the operations of the US-Chinese social media platform.


On Monday, officials from the White House revealed that US software company Oracle would license TikTok’s recommended algorithm as part of the agreement. This collaboration expands the existing management of TikTok data collected from US users.


The US president had a phone conversation with Chinese President Xi Jinping on Friday, sharing on Truth Social that the call was “very good” and expressing gratitude for “TikTok’s approval.” Earlier in the week, leaders from both countries met in Madrid, Spain, to discuss trade agreements related to TikTok’s ownership.

The status of popular apps in the US has been uncertain for over a year, stemming from a 2024 Congressional vote that overwhelmingly approved a law banning social media apps unless they could find US buyers. The Supreme Court upheld the law in January, but on his first day in office, Trump signed an executive order delaying the ban. He has consistently postponed TikTok’s ban, which was initially his proposal, until a deal could be finalized.

Here’s what we know about the forthcoming agreements, including the involvement of media moguls and Oracle’s Larry Ellison alongside the Murdoch family, who recently surpassed Elon Musk as the richest individuals globally:


What are the terms of the transaction?

The deal aims to keep TikTok operational in the US, but under new ownership that is not linked to China. Lawmakers argue that a popular social media app owned by a Chinese entity poses risks, enabling potential propaganda spread among its 180 million US users.


At least 12 investors have shown interest in acquiring TikTok, including a consortium led by software giant Oracle. A complete roster of investors has yet to be disclosed. According to White House officials, Oracle is responsible for managing data for US users and overseeing TikTok’s influential recommendation algorithms, ensuring that information remains outside the jurisdiction of Chinese authorities.

ByteDance will ultimately retain less than 20% ownership of the app, as White House officials told Reuters, with US TikTok operations managed by a blend of existing US and global firms, along with new investors devoid of ties to Chinese authorities.

The agreement mandates that all data pertaining to US users be stored domestically within cloud infrastructure managed by Oracle.


Who is involved?

Trump mentioned in a Fox News Sunday interview that media tycoon Rupert Murdoch and his son Lachlan, CEO of Fox Corporation, might join the deal. He also indicated that Michael Dell, CEO of Dell Technologies, is involved.


Larry Ellison, co-founder of Oracle, has been a key player among the potential buyers for quite some time. He leads a consortium that includes asset manager Blackstone, private equity firm Silverlake, Walmart, and billionaire Frank McCourt.

According to Reuters, the US government will not have a seat on the board or a golden share in the new entity that owns TikTok within the US. It remains uncertain if the US government will receive financial considerations as a condition for approval.


Why is this happening?

The prospect of banning TikTok began with Trump in 2020, citing that apps owned by China pose national security risks. This issue soon garnered bipartisan consensus, leading Congress to overwhelmingly pass a law last year that mandated the app’s ban unless sold by its Chinese owners. The initial deadline for TikTok’s ban was set for January 19th.


After embracing the app during his presidential campaign last year, Trump shifted his perspective on TikTok, gaining millions of followers and hosting TikTok CEO Shaw Chew at Mar-a-Lago and the White House. The president has praised social media platforms for enhancing his connection with younger voters in the 2024 election.

Trump issued the first executive order in January to delay the TikTok ban, subsequently signing three more orders to postpone enforcement until a deal could be reached. Currently, the president is delaying the enforcement of the law until mid-December, as transaction details are settled to ensure the new ownership is eligible for a complete sale.


What does the executive order do?

The order is expected to delineate the framework of the TikTok transaction and ensure the agreement complies with US law. The proposal reportedly includes a seven-member board comprised of Americans, and TikTok’s algorithm will be leased to the new US owner.


Trump’s executive order is anticipated to feature a new 120-day suspension of enforcement to facilitate investors and finalizing contracts.


Does China agree?

The US is optimistic about China’s approval of the deal and doesn’t plan further discussions with Beijing on the details, as White House officials explained to reporters during a conference call. However, they noted that additional documentation from both parties would be necessary for deal approval.


China has yet to confirm its approval of the transaction. ByteDance stated that while discussions about the app’s resolution are ongoing with the US government, any contracts will be “subject to approval under Chinese law.”

Optimizing Your Cortisol Rhythm: How to Make It Your New Normal

Feeling exhausted? Has bloating become a concern? Are sleepless nights troubling you? Your cortisol levels might be elevated – at least that’s the prevailing notion on social media.

Cortisol has recently garnered attention from various health and wellness influencers, who attribute all sorts of issues to it. Fortunately, this is a challenge that can often be addressed with the right blend of supplements.

But what is cortisol exactly? And why has it become a source of so much concern?

Cortisol is widely recognized as a stress hormone. When faced with a potential danger, the amygdala in your brain activates a “fight or flight” mechanism. This leads to the release of adrenaline and noradrenaline, preparing your body to either confront or flee from the threat. You might feel this rush when startled by a scary movie or while feeling anxious before a big presentation.

In most instances, stress is temporary – fear is immediate, and presentations are often short-lived – allowing our adrenaline levels to stabilize shortly afterward. Neuroscientists and psychologists refer to this as acute stress, which in moderation can actually be beneficial for us.

Cortisol comes into play when stress is prolonged or perceived as unmanageable. In these situations, cortisol is secreted from the adrenal glands situated above the kidneys.

This release peaks after about 15-20 minutes, during which it helps the body sustain its response to threats by ensuring energy availability, maintaining blood flow to muscles, and keeping the brain alert.

However, this isn’t the case for every instance of fear or stress. “It’s quite difficult to trigger a cortisol response from acute stress,” says Professor Stafford Reitman from the University of Bristol School of Medicine.

“While it’s easy to evoke an adrenaline response, initiating cortisol release is more complex, as it depends on how you personally perceive a situation as a genuine threat.”

A 2025 study involving 201 healthy volunteers found that cortisol levels peaked just before waking.

Nonetheless, cortisol’s role extends beyond stress responses. It has several essential functions, some of which are beneficial. For instance, cortisol plays a crucial role in helping you rise in the morning: your cortisol levels increase before you wake up. Without this morning boost, getting out of bed would be even more challenging.

Cortisol is involved in various functions, as Reitman notes. “Cortisol acts as a signaling molecule. Almost every tissue in the body possesses cortisol receptors, found in the muscles, liver, and brain.”

When organs and muscles receive cortisol signals, they trigger vital processes that stabilize the body. For example, when organs like the liver or pancreas detect cortisol, they help maintain stable blood sugar levels and consistent blood pressure. Additionally, cortisol can initiate anti-inflammatory responses within the body, providing short bursts of immune system support.

“Cortisol performs multiple tasks,” Lightman explains. “Its regulation is critically important, as it’s the only hormone essential for life – without cortisol, survival is impossible.”

Understanding Patterns

Clearly, some cortisol is necessary, but what if you’re concerned about having too much?

This can be tricky to assess because cortisol levels naturally fluctuate throughout the day (rising in the morning and declining by evening). The challenge is that home test kits used for measuring cortisol typically capture a single snapshot each day, labeling levels as “high” or “low.”

Lightman describes these tests as “utterly inadequate,” noting that “normal fluctuations can vary widely at any given moment, making it difficult to determine whether someone’s cortisol level is truly high or low. Levels could differ completely just 20 minutes later.”

For an accurate assessment, you’ll need to track cortisol over several days. This is how healthcare professionals diagnose conditions related to cortisol release abnormalities.

Moreover, cortisol tends to be released in bursts approximately every hour. This release pattern influences gene activity and is critical for numerous bodily functions. One study investigating this involved healthy volunteers undergoing cortisol suppression, then receiving matching doses that either mimicked a non-pulsed daily (circadian) pattern or a pulsatile circadian rhythm (akin to natural cortisol release).

Participants following the non-pulsed protocol exhibited declines in working memory tasks and sleep quality. However, those in the pulsed protocol were less adept at identifying facial expressions linked to improved mental health compared to their counterparts. The findings suggest that the release pattern may be crucial for functionality rather than merely the cortisol amount present.

Research involving mice indicates that higher cortisol levels may facilitate neuronal connections, aiding in more effective skill acquisition. However, adequate cortisol levels are imperative for learning new skills. These connections are retained in the brain for extended periods.

Even if continuous tracking of cortisol were possible, it wouldn’t necessarily inform your health status. “You first need to establish what’s considered normal for an individual,” Reitman emphasizes. “Then it becomes evident if their daily pattern deviates from that norm. No one has performed this assessment. Claims of ‘dysregulated patterns’ are misleading,” he asserts.

Incorporating the Japanese practice of “Shinrin Yoku” or forest bathing has consistently been shown to lower cortisol levels – Getty

Stay Calm

Scientists concur that chronic stress can negatively impact our health, and managing it can improve our quality of life. However, Reitman advises against hastily attributing health issues to cortisol.

“Experiencing long-term stress from events like divorce, job loss, or restless nights can lead to health problems, but this doesn’t necessarily mean cortisol is the culprit.”

Addressing the underlying causes of stress is often the most effective treatment, rather than relying on supplements to reduce cortisol levels, although this may not always be viable.

Fortunately, there are various strategies available for managing stress. For instance, a 2019 survey revealed that older adults who engaged in three months of dance training experienced lower peak cortisol levels. Dance has also been shown to reduce stress.

Additionally, physical affection can be effective in managing immediate stress levels. One study indicated that students receiving more hugs than usual experienced lower morning cortisol spikes the following day.

Spending time in nature, such as walking through forests, has also proven beneficial. One study found that forest bathing can reduce cortisol levels by 53%.

Unless you’re a villain, cortisol is crucial for our body and brain; for most of us, worrying about it is hardly necessary.

It’s best to steer clear of influencers selling the latest health trends and focus instead on the fundamentals of healthy living (diet, exercise, sleep) – especially when true joy can often be found in the real world.

Hubble Space Telescope Reveals Stunning New Images of NGC 2775

The prominent, yellowish bulge at the core of NGC 2775 is populated with older stars, encircled by tightly wound spiral arms adorned with areas of dark dust and young blue stars.



This Hubble image captures NGC 2775, a galaxy located approximately 67 million light years away in the Cancer constellation. Image credits: NASA/ESA/Hubble/F. Belfiore/J. Lee/Phangs-HST team.

NGC 2775 is situated about 67 million light years from the northern constellation of Cancer.

This galaxy was discovered on December 19, 1783, by British astronomer William Herschel, who was originally from Germany.

NGC 2775 is a principal member of the Galaxy’s Anti-Rahydra Cloud and part of a small group of galaxies known as the NGC 2775 group.

Also referred to as Caldwell 48, Leda 25861, or UGC 4820, NGC 2775 has a diameter of approximately 80,000 light years.

“NGC 2775 has an unusually smooth center that is devoid of gases, resembling an elliptical galaxy,” noted Hubble astronomers in a statement.

“It contains dusty rings with clusters of patchy stars, similar to spiral galaxies.

“Observing NGC 2775 from a single perspective makes it challenging to ascertain its true nature.”

“While some researchers classify NGC 2775 as a spiral galaxy due to its star and dust patterns resembling feathered rings, others categorize it as a lenticular galaxy.”

“Lenticular galaxies exhibit characteristics of both spiral and elliptical types.”

“The exact appearance of a lenticular galaxy remains uncertain, as they can form in various ways.”

“Some lenticular galaxies may have originated as spiral galaxies that fused with one another or may have lost their star-forming gas and prominent spiral arms.”

“They might also have accumulated gas in their surrounding discs, leading them to appear more oval-shaped.”

Astronomers suggest that NGC 2775 may have merged with other galaxies in the past.

“In the Hubble image, NGC 2775 features a hydrogen gas tail extending nearly 100,000 light years around the galaxy,” the researchers indicated.

“This faint tail could represent the remnants of one or more galaxies that ventured too close to NGC 2775 before being absorbed.”

“If NGC 2775 has indeed merged with other galaxies previously, it could help to explain the unusual appearance of the galaxy as we observe it today.”

“Hubble’s images of NGC 2775 were released earlier in 2020,” they added.

“The updated version includes observations of specific wavelengths of red light emitted by hydrogen gas clouds surrounding the young giant star.”

Fossils from the Oligocene Cycle Reveal Pollination Interactions Between Flowers and Marchalace

Paleontologists have examined fossilized flowers and bees dating back 24 million years, following the scarcity in Enspel, Germany, and unveiled new species of Linden. These include Tilia Magna Separa and two newly identified bumblebee species, Bombos (Chrono Bombos) Mesegas and Timebombus Palaeocrater. The presence of identical tyria pollen in both the flowers and on the outer surfaces of the bumblebees serves as direct evidence of their interactions, identifying Bombos as a pollinator of Tyria. At least due to the late decline, we remain anchored in the present.

Tilia Magna Separa. Image credit: Christian Geier.

“We analyzed countless fossil flowers and insect pollens in hopes of understanding the evolution of flowers, their visitors, and the pollination process,” stated Dr. Friðgeir Grímsson, a researcher at the University of Vienna.

“These microscopic pollen grains were made visible using UV and blue light, and then extracted individually from flower or insect hair, or aggregated from insects, with the aid of extremely thin needles and minimal invasive techniques.”

The pollen grains underwent careful washing and were analyzed using high-resolution light and electron microscopes.

Many of the flowers studied originated from Linden trees, with numerous bumblebees visiting Linden flowers prior to their fossilization in an ancient volcanic crater lake.

“The newly identified linden flower has been named Tilia Magna Separa,” said Christian Geier, a doctoral student at the University of Vienna.

“Additionally, two new bumblebee species have been identified: Bombos (Chrono Bombos) Mesegas and Bombos (Time Bombos) Pereoctor.”

The fossils were uncovered during the excavation of lake sediments from the former volcanic lake near Enspel in Rhineland-Palatinate, Germany.

Tilia Magna Separa marks the first recorded flowers from the European continent, characterized and described as per pollenological standards—the science of pollen,” the researchers noted.

“The fossil bumblebees rank among the oldest representatives of their genus, with only one species from Colorado, USA, predating them.”

“This is the first instance globally where a fossil flower and its pollinator bee have been described arising from the same deposits, with pollen linking them directly,” Geier remarked.

“Such research holds significant potential to enhance our understanding of past pollinator dynamics.”

The Fossil Record offers insights into the evolutionary developments of the past, revealing changes due to climate shifts, species extinction, and evolutionary adaptation.

By analyzing fossilized animal and plant groups, we can infer their behaviors and reactions to environmental changes.

“Our research allowed us to identify specific flower homeostasis among the bumblebees studied,” Geier explained.

“This indicates that they tend to visit only one type of plant during a single flight.”

“These findings are crucial for gaining a deeper understanding of the delicate interactions and resilience within today’s ecosystems.”

The study was published today in the journal New Botanist.

Astronomers Uncover the Most Distant Black Hole Ever Detected

A newly identified supermassive black hole resides in the center of the “Little Red Dot” galaxy, known as Capers-LRD-Z9, existing merely 500 million years after the Big Bang.



Artistic impressions of Capers-Lrd-Z9. Image credit: Erik Zumalt, University of Texas, Austin.

“Finding a black hole like this pushes the limits of what we can currently detect,” remarked Dr. Anthony Taylor, a postdoctoral researcher at the University of Texas at Austin.

“We’re truly expanding the boundaries of technological capability today.”

“While astronomers have identified more distant candidates, clear spectroscopic signatures for black holes have yet to be found,” noted Dr. Stephen Finkelstein from the University of Texas at Austin.

The astronomers conducted their research using data from the NASA/ESA/CSA James Webb Space Telescope, as part of the CAPERS (Candels-Area Prism Epoch of Reionization Survey) program.

Initially regarded as a mere speck in the program images, Capers-LRD-Z9 is now recognized as part of a newly classified category of galaxies called Little Red Dots.

“The find of the Little Red Dot was a surprising revelation from initial Webb data. It did not resemble the galaxies captured by the NASA/ESA Hubble Space Telescope,” Dr. Finkelstein explained.

“We are currently working to understand what they are and how they formed.”

Capers-Lrd-Z9 contributes to the growing evidence that the ultra-large black hole plays a critical role in the unusual luminosity of small red dots.

Typically, such brightness signifies a galaxy teeming with stars. However, in the absence of substantial stellar mass, these small red dots cease to exist.

These galaxies may also help clarify what causes the distinct red hue observed in small red dots, which is altered to a red wavelength as it passes through surrounding gas clouds encircling the black hole.

“I’ve observed these clouds in other galaxies,” Dr. Taylor stated.

“When I compared this object to others, it was unmistakable.”

Capers-LRD-Z9 merits attention due to the immense size of its black hole.

It’s estimated to be as massive as 300 million solar masses, equating to half the total star mass within the galaxy. This size is notably large, even among supermassive black holes.

By discovering such massive black holes early on, astronomers provide a unique opportunity to investigate the growth and evolution of these entities.

Black holes existing in later epochs had diverse opportunities for growth over their lifetimes, yet this was not the case during the initial hundreds of millions of years.

“This reinforces the increasing evidence that early black holes grew much faster than previously believed,” Dr. Finkelstein mentioned.

“Or they might have originated much larger than our models suggested.”

These findings are detailed in a paper published in the Astrophysical Journal.

Paleontologists Uncover a New Species of Iguanodon Dinosaur

A collaborative team of paleontologists from Portugal, Italy, the United States, and Belgium has enriched their paleontological records with the identification of a new herbivorous dinosaur species: Cariocecus bocagei.



Cariocecus bocagei. Image credit: Victor Feijó de Carvalho.

Cariocecus bocagei inhabited what is now known as Portugal during the Valemia period of the Cretaceous, approximately 125 million years ago.

This newly identified species belonged to the medium-sized Iguanodon group, which includes robust herbivorous dinosaurs with intricate teeth structures.

“The Iguanodon faction plays a significant role in the herbivorous dinosaur fauna across various ecosystems of the Cretaceous period,” stated Dr. Filippo Bertozzo, a paleontologist at the Royal Institute of Natural Sciences and ci2paleo (Centro de Perebierosia de Nature Ecology, Paleontology of Rehabilitation Therapy).

“At the conclusion of the Jurassic, the Iguanodon factions exhibited limited diversity and body size, with the largest being Camptosaurus.

“These dinosaurs were primarily restricted to the central part of the northern landmass of the Jurassic, which now includes modern-day Wyoming, Tanzania, and Portugal.”

“By the mid-Cretaceous, these clades had achieved a worldwide distribution,” they further commented.

“The selective pressures and environmental factors that drove this diversification during the Jurassic to Cretaceous transition remain poorly understood, largely due to the scarcity of iguanodontian fossils in various regions, such as South Africa.

“The Iguanodon faction was among the first dinosaurs to be discovered and researched, with ongoing studies aimed at exploring the anatomical features and their functions,” they remarked.

“Nonetheless, various aspects of the skull, from the function of the supraorbital bone to paleoneurology and sensory systems, continue to be elusive.”

The partial skull of Cariocecus bocagei was uncovered in 2016 along the cliffs of West Portugal from the Paposeco Formation.

This specimen, measuring approximately 37 cm long, is the first Iguanodontian skull recorded in the country.

“The specimen was excavated from the Seco Formation of Papo along the southern coast of the Setubal Peninsula, roughly 200 meters north of Praia de Areia do Mastro,” noted the paleontologist.

“A comprehensive sequence analysis indicates that the early Cretaceous layers found along this coastline were deposited during the fourth and final uplift episodes related to the formation of the Lusitania Basin.”

Upon examining the fossils, researchers identified anatomical characteristics not observed in other Iguanodon species.

“The upper jaw and Jugal bones are flawlessly fused. I have never encountered this in any other iguanodon,” Dr. Bertozzo expressed.

“This isn’t a random anomaly; it’s a genuinely unique feature, confirming it as a new species.”

MicroCT scans enabled scientists to explore the cranial nerves and inner ear with remarkable detail.

“A skull discovery is always significant. It reveals much more than isolated bones,” Dr. Bertozzo commented.

“In this instance, you can observe the impressions of the brain and nerves and even reconstruct parts of the inner ear.”

“The structure of the balance organs and auditory nerves offers insights into how this animal lived and oriented itself.”

“Another notable feature is the unusually low ‘brow’ bones, lower than those of other known Iguanodon factions.”

“This likely supported a heavy brow ridge akin to that of modern eagles.”

“Such structures may have implications for functionality or visibility.”

“The teeth of Cariocecus bocagei also provided remarkable insights,” he added.

“MicroCT scans uncovered not only visible teeth but also replacement teeth embedded within the jaw, designed to replace those that have worn down.”

“This tooth replacement mechanism is characteristic of iguanodons but is rarely observed in earlier species.”

The research team speculates that Cariocecus bocagei may have possessed a stronger bite relative to its kin.

“The discovery of Cariocecus bocagei enhances our understanding of the ecological dynamics within the Lusitania Basin’s early Cretaceous environment, indicating the presence of multiple Iguanodon species, reflecting trends seen in other symbiotic habitats in the UK, Belgium, Spain, and Central Africa,” the authors stated.

“The Valemian diversity in Iguanodon taxa resulted from island endemic events that emerged following the dispersal of dry morphs in North America during the Late Jurassic and Late Cretaceous periods.”

“In conclusion, the discovery of Cariocecus bocagei emphasizes the significance of the Balemian Psien of Hauteribia in the diversification and speciation of Iguanodonians, ultimately leading to the evolution of the more advanced Hadrosaurus in the Turonian period.”

Survey results were published in the Journal of Systematic Palaeontology.

U.S. Rivers Face Unprecedented and Severe Impacts from Global Warming

Rivers across the United States are experiencing increasing temperatures.

A recent analysis of nearly 1,500 river locations spanning over 40 years reveals a rise in the frequency, intensity, and duration of heat waves, posing risks to many species accustomed to cooler waters.

“The increase in river heat waves is actually outpacing that of air heat waves, which is quite surprising,” states Li Li, a professor of environmental engineering at Pennsylvania State University and the study’s author.

A new analysis published in the peer-reviewed journal Proceedings of the National Academy of Sciences is the first comprehensive study defining river heat waves as five consecutive hot days compared to seasonal averages.

The researchers identified climate change, which significantly impacts humans, as a major contributor to this trend, due to diminishing snowpacks and slower stream flows.

Human factors also play a role; for example, dams inhibit downstream flow, while urban structures absorb heat, warming both air and water.

Scientists are concerned that species reliant on cold water, such as salmon and trout, will increasingly struggle as river temperatures rise. Li emphasizes the necessity of tracking fish fatalities and ongoing trends.

Higher temperatures decrease the amount of dissolved oxygen in water. Additionally, cold water species generally exhibit increased metabolism in warmer conditions, leading to further oxygen depletion.

These findings could influence basin management strategies and help determine if adjustments in irrigation or dam releases can support aquatic life during elevated temperatures.

“Water management practices can significantly impact heat waves,” noted Jonathan Walter, a research scientist at UC Davis’ Center for Watershed Sciences, who was not part of the study. “If there is sufficient reservoir water, it may be feasible to moderate downstream temperatures by releasing water to mitigate extreme heat.”

While heat waves in oceans and lakes have been studied extensively, there has been limited research on the implications of rising temperatures in rivers until now.

Satellite data have advanced the study of ocean and lake heat, but river temperature research is challenged by reliance on often unusable river gauge sensors, resulting in significant data gaps.

For this new study, researchers analyzed data from 1,471 US Geological Survey monitoring sites from 1980 to 2022.

This data enabled an assessment of shifts in streams nationwide, revealing that by 2022, river heat waves were occurring more frequently than in 1980, with an average increase of 1.8 additional heatwave events per year. These heat waves were also more severe, with temperatures during these events being approximately 0.8 degrees Fahrenheit higher in 2022 than in 1980. Moreover, the duration of heat wave events extended by over three days.

Li noted that this extra heat caused an average of about 12 days of heat stress for cold water species. The study defined 59°F as the threshold for heat stress, as many species, including bull trout, face survival challenges at this temperature.

“When considering water, its visibility draws attention to its significance,” Li remarked. “We hope this research raises public awareness on water quality challenges stemming from climate change.”

Strange Discovery: Venus Features a Lava Tube

SEI 267222984

We are gaining knowledge about Venus, a high-pressure planet

JSC/NASA

There is compelling evidence that vast underground tunnels have been formed from lava on Venus. These formations are unusually wide and distinct from those found on other celestial bodies.

It is generally accepted that underground tunnels, carved through lava, exist as lava tubes on Earth, the Moon, and Mars. Smaller, low-gravity planets tend to develop more porous tubes as their rocky walls are less susceptible to collapse due to weaker gravity. For instance, the Moon has such large tubes that scientists have proposed utilizing them as habitats for astronauts, shielding them from intense solar winds.

Researchers have observed indications of these lava tubes on Venus, evident from surface holes that may have been formed by the underground features or by other geological activities associated with its active fault lines.

Recently, Barbara de Tofoli from the University of Padova in Italy along with her colleagues uncovered direct evidence of these lava tubes on Venus. Remarkably, despite Venus’s similarities to Earth regarding its mass and gravity, its lava tubes appear to be surprisingly wide, with a volume comparable to those found on the Moon.

“While Earth has a small number of lava tubes, Mars has a slightly larger count, and the Moon has even more. Venus disrupts this trend by featuring incredibly large tubes, indicating its potential significance,” she stated at the Europlanet Science Congress in Helsinki, Finland, earlier this month.

De Tofoli and her team used radar and mapping data from previous missions to examine the alignment of these pits near large volcanoes. They identified four distinct sites where alternative geological explanations, such as structural activities, were implausible. The pits were also found to align with the steepest sections of volcanic slopes, consistent with the movement of lava. Their depth-to-width ratio corresponded with known lava tubes.

The unexpectedly large size of these tubes, especially their width, implies that the extreme conditions on Venus, characterized by high temperatures and pressure, can influence the movement of molten rock beneath the surface. “Due to the extremely high pressure, the floor of these tubes is not eroded as intensely as it typically is on other planets; instead, it remains largely flat throughout the tube.”

Scientists Reveal That Liquid Water Once Flowed Through the Parent Body of Asteroid Ryugu

This water flow took place on ancient asteroids over a billion years after their formation, likely due to the heat generated by melting ice, which caused rock fractures that facilitated water movement. JAXA’s Hayabusa-2 Spacecraft.

This image of the asteroid was taken on June 26, 2018, by JAXA’s Hayabusa-2 Spacecraft optical navigation camera – telescopic (ONC-T). Image credits: JAXA / University of Tokyo / Kochi University / Ricchiho University / Nagoya University / Chiba University of Technology / Nishimura University / Aizu University / AIST.

Ryugu is a CG-type asteroid close to Earth and part of the Polana family of impact asteroids.

The diamond-shaped body, also known as 1999 JU3, was identified by astronomers in May 1999 during asteroid studies near Lincoln.

Its diameter measures about 900 m (0.56 miles), and it orbits the Sun at a distance of 0.96-1.41 Astronomical Units (AU) every 474 days.

“We have a relatively good understanding of how the solar system was formed, though many gaps remain,” said Shiyoshijima, a researcher at the University of Tokyo.

“One gap in our knowledge is how Earth acquired its water.”

“It has long been known that carbonaceous asteroids, originating from ice and dust in the outer solar system, have contributed water to Earth.”

“We discovered that Ryugu preserves an unaltered record of water activity, indicating that liquid water moved through the rock much later than previously anticipated,” added Dr. Ikemoto.

“This shifts our understanding of the long-term fate of water on asteroids. The water has remained for an extended period and hasn’t been depleted as quickly as we thought.”

In this study, the authors examined the isotopes of lutetium (Lu) and hafnium (HF), with the radioactive decay from lutetium-176 to hafnium-176 serving as a sort of clock to gauge geological processes.

The expected presence of these isotopes in the studied sample was hypothesized to correlate with the asteroid’s age in a predictable manner.

However, the ratio of Hafnium-176 to Lutetium-176 was significantly unexpected.

This strongly suggests to researchers that the liquid effectively washed away lutetium from the rocks containing it.

“We anticipated that Ryugu’s chemical signatures would align with certain meteorites currently under examination on Earth,” Dr. Iizuka stated.

“However, the results were strikingly different, necessitating the careful elimination of other possible explanations, ultimately concluding that the Lu-HF system was hindered by a delayed liquid flow.”

“The most probable triggers involved the parent body of Ryugu’s larger asteroid, which disrupted the rocks, melting the embedded ice and allowing liquid water to permeate the body.”

“It was truly surprising! This impact event could be the catalyst for the parent body disruption.”

One of the crucial implications is that carbon-rich asteroids may be a significant source of water for Earth, supplying far more than previously estimated.

Ryugu’s parent body seems to have retained ice for over a billion years. This suggests that similar bodies impacting the young Earth could have delivered 2-3 times more water than standard models predict, significantly influencing the planet’s early oceans and atmosphere.

“The notion that a Ryugu-like object has preserved ice for such an extended time is remarkable,” Dr. Ikemoto remarked.

“It implies that Earth’s components were far wetter than we had imagined.”

“This prompts a reevaluation of the initial conditions for the planetary water system.”

“It’s still early to draw definitive conclusions, but my team and others may build on this research to clarify various aspects, including how our planet became habitable.”

The findings will be published in the journal Nature.

How Do Small Galaxies Acquire Their Magnetic Fields? – Sciworthy

Among the four fundamental forces in the universe, gravity often comes to mind when considering cosmic phenomena. This is quite logical, as gravity operates over vast distances, exerting its influence on massive objects, making it the most significant and far-reaching force. However, another essential force, known as electromagnetism, also plays a critical role in the study of space.

To begin with, all light is made up of electromagnetic radiation, which consists of oscillating electric and magnetic fields. This includes everything from radio waves to visible light and X-rays. Similar to Earth and the Sun, many celestial bodies are enveloped in magnetic fields. The Earth’s magnetic field serves as a shield against harmful radiation, while the solar magnetic field repels it. The generation of a magnetic field requires the movement of charged particles, such as protons and electrons. Consequently, a variety of objects, including entire galaxies, possess magnetic fields!

Researchers are aware that galaxies have magnetic fields, but it remains uncertain how various galaxies develop different magnetic intensities or how these fields influence their evolution over time. This investigation is further complicated by the fact that galaxies often exist in clusters. For instance, the Milky Way is surrounded by smaller galaxies known as satellites, which exert gravitational pull on each other and interfere with each other’s magnetic fields.

The research team explored how diverse environments in smaller galaxies affected the strength of their magnetic fields. They approached this by simulating the motion of materials within the galaxy as if they were liquids filled with striped particles. Two sets of simulations were conducted, the second of which also included the effects of high-energy particles known as cosmic rays.

In total, they simulated magnetic fields across 13 distinct scenarios, ranging from isolated galaxies with masses 10 billion times that of the Sun to those 10 trillion times greater, accompanied by up to 33 satellites. Each simulation commenced with galaxies exhibiting a magnetic field strength of 10-14 Gauss (g). For context, Earth’s magnetic field strength is about 0.3-0.6 g. The scenarios were evolved over 12 billion simulation years, allowing galaxies to interact, traverse space, and form stars, subsequently tracking the magnetic field strength in smaller galaxies.

Throughout the simulated timeline, the magnetic fields of all galaxies strengthened as star formation progressed. The birth of stars stirs the galactic matter, enhancing magnetic field strength and producing cosmic rays. Most galaxies concluded with magnetic fields ranging from 10-7 to 10-6 G, with larger galaxies typically achieving stronger fields. Interestingly, the researchers found that small galaxies passing in close proximity to larger companions exhibited stronger magnetic fields than equivalent isolated galaxies.

They monitored satellite galaxies over a series of simulations and discovered that, on average, magnetic field strength increased by 2-8 times as these galaxies approached their host. In extreme cases, the satellite’s magnetic field intensified by up to 15 times after nearing the host. In contrast, satellite galaxies that were more distant or had not yet approached their host did not show such significant increases in magnetic field strength.

The researchers interpret their findings to suggest that the more turbulent the interstellar medium (ISM) within a galaxy, the greater the strength of its magnetic field. Orbiting near a host galaxy tends to disturb the ISM of the satellite galaxy, rendering it more magnetic than a solitary small galaxy. Approaching a massive galaxy compresses the satellite, exposing it to magnetizing materials, and both interactions contribute to amplifying the magnetic field strength.

The team recommends that future studies utilize these results to inform radio and gamma-ray observations of galaxies, as these two segments of the electromagnetic spectrum can provide astronomers insights into the magnetic field properties of celestial bodies. They also caution that astronomers conducting simulations of isolated galaxies might yield skewed results since such a scenario does not accurately reflect the reality in which many galaxies are in proximity to companions.

Amazon Deforestation Leads to Severe Rain, Wind, and Heat Events

Illegal deforestation in the Amazon of Mato Grosso, Brazil

Paralaxis/Alamy

Life in the Amazon post-deforestation presents a grim scenario. Strong winds impede the recovery of the forest, while rising temperatures result in heat stress for both inhabitants and wildlife.

This contradicts the common belief that rainforest removal leads to a drier local climate.

Many studies suggest that deforestation in the Amazon will significantly reduce rainfall, but these studies often rely on low-resolution models that fail to accurately depict convection patterns in the region.

Recently, Alim Yun from the Max Planck Institute for Meteorology in Germany and her team have employed advanced climate models to represent rainforest rainfall dynamics and convection more accurately.

Dominic Spracklen, at the University of Leeds in the UK, which was not involved in the study, regards this methodology as “highly commendable,” suggesting it could “enhance predictions of climate responses to deforestation.”

Using this innovative approach, Yoon previously reported that under current climatic conditions, a complete deforestation of the Amazon would yield relatively stable average annual rainfall. The ongoing research aims to analyze how hourly patterns of rain, heat, and wind shift in this complete deforestation scenario.

The team’s findings indicate an increase in the frequency of dry spells, with a 54% rise in severe rainfall events. Concurrently, daily temperature extremes rise by 2.7°C (4.9°F) and 5.4°C (9.7°F), significantly heightening heat stress among local populations. Moreover, extremely strong winds are becoming more prevalent.

Over 30 million individuals reside in the Amazon region, including around 2.7 million indigenous people. “Expect intensified rainfall and extreme temperatures,” warns Lewis Catterrand from the University of Leeds. “This is alarming for everyone in the area.”

However, he cautions that further validation of this modeling approach is necessary. Additional research is essential to explore the effects of partial deforestation on the local climate in light of future projections for the region. “These extreme scenarios are meant to aid scientists in understanding the implications, but we know they don’t paint a complete picture,” says Catterrand.

Three Essential Guidelines for an Effective Post-Workout Diet

Are carbohydrates, proteins, and liquids the foundations of your post-exercise diet?

cream_ph/getty images

When it comes to exercise, I’m not particularly focused on enhancing my performance or optimizing my biology. My primary goal is simply to remain active. Consequently, I have not given much thought to my post-exercise nutrition. However, training for a half marathon has illustrated to me the significance of properly fueling my body, and that it doesn’t need to be complicated.

It’s essential to understand that your post-exercise nutritional requirements can differ based on several factors, including the type of exercise you engage in, your age, gender, genetics, and more. Nonetheless, an April review in Sports Medicine discovered compelling evidence regarding three key interventions that enhance muscle recovery and performance. I consider these as foundational elements of a post-exercise diet.

The first element is carbohydrates. During exercise, your body taps into energy stores found in the liver and muscles. Replenishing these stores is vital to prevent muscle breakdown and ensure adequate energy for your next workout. Carbohydrates serve as the most effective source of this energy because they are quickly converted into usable fuel.

The review suggests that after four hours of intense exertion, athletes should consume 1-1.2 grams of carbohydrates per kilogram of body weight per hour. While this guidance may be geared more toward athletes, it’s advisable for all adults to consider a carbohydrate-rich snack or meal post-exercise. Opt for options that include both glucose and fructose, as glucose helps restore muscle energy and replenishes liver stores. Fruits are perfect, as they provide both.

The second element is protein, which is crucial for muscle recovery. Combining protein with carbohydrates has been shown to enhance performance. A 2016 study involving eight athletes indicated that those who consumed both macronutrients within two hours after an intense cycling session could ride an average of 14 minutes longer in their subsequent workout compared to those who only ingested carbohydrates. The timing of protein intake matters less than the quantity consumed. Reviews in Sports Medicine recommend 20-40 grams of protein after exercise.

study involving 72 men (also published in 2016) demonstrated that oral supplement solutions, milk, and orange juice were found to be more hydrating than water due to their electrolyte content, which aids in hydration and retention. Beverages like tea, coffee, soft drinks, and even beer provided hydration levels similar to water. Though I’m not advocating for pints post-workout, if water isn’t appealing, choose something delicious that you enjoy.

I still prefer simplicity, but now I focus on these three core elements. My favorite choice is a smoothie made with frozen fruits, orange juice, and protein powder. Although it’s not perfectly optimized, it represents an improvement. And it always satisfies my cravings after a run.

Books vs. Audiobooks: Is Reading Always More Beneficial for the Brain Than Listening?

Engaging with information can alter how your brain processes and reacts to it

Tony Anderson/Getty Images

As a passionate reader and writer, I often find myself disheartened. Recent reports indicate a decline in reading for enjoyment among younger generations. When a friend asked if her use of audiobooks provided the same cognitive benefits as traditional reading for her daughter, my initial thought was, “Enjoyment matters more than the format.” However, exploring the science revealed that the medium indeed influences our cognitive process in important and distinct ways.

The Advantages of Reading

Reading unquestionably benefits us. Aside from the knowledge it imparts and the opportunities it opens up, numerous studies link childhood literacy with both physical and mental well-being – and even extended lifespans.

It is believed that reading exercises three crucial cognitive functions. Firstly, it promotes “Deep Reading,” allowing us to connect different sections of text, reflect on their relevance to our lives, and engage with the material critically.

Secondly, reading fosters empathy and bolsters our emotional intelligence—traits that are essential for coping with stress and navigating real-life difficulties. Thirdly, there exists a correlation between reading and cognitive development. The “Theory of Mind” refers to our ability to recognize that others may hold different thoughts and beliefs than we do.

However, discerning the impact of reading from other influences can be challenging. Moreover, readers may enjoy advantages like having leisure time, financial resources, or even genetic traits which can affect overall health, cognition, or longevity.

Nevertheless, a study involving over 3,500 participants attempted to account for these factors, revealing that individuals who read for approximately 30 minutes each day were 20% less likely to pass away in the subsequent 12 years. This benefit was more pronounced among book readers compared to those who primarily read newspapers and magazines.

Digital Media: E-readers and Audiobooks

Comparing print reading to digital formats complicates the research landscape. Some studies suggest that screen reading promotes a more superficial understanding compared to reading printed material.

There are also subtle differences. In a series of experiments conducted by Anne Mangen from Stavanger University, Norway, and Frank Hakemalder from Utrecht University in the Netherlands, it was found that frequent readers of short texts on screens tended to seek meaning less diligently than their paper-reading counterparts. Additionally, increased exposure to screen reading correlated with diminished persistence in tackling longer literary works.

Concerning audiobooks, while the evidence remains limited, I find some solace in the findings. Research indicates that comprehension levels are very similar whether one is reading or listening. However, some nuances exist—meta-analyses of 46 studies discovered that reading provides a slight advantage for interpreting the emotions of characters, among other interpretative skills. Thus, drawing inferences from the text is somewhat more effective when reading.

Diverse Cognitive Approaches

Interestingly, listening rather than reading seems to engage different cognitive aspects. For instance, research shows that individuals tended to think more intuitively when responding to verbal questions compared to written ones.

Listening to an audiobook provides the experience of hearing another person’s voice with its unique intonations, rhythms, and emotions, which can greatly influence interpretation. Janet Gaipel from the University of Exeter notes that contrastingly, reading relies on our inner voice, allowing for a more individualized and self-paced experience. These distinctions may significantly affect how information is perceived and utilized.

Nonetheless, “listening to audiobooks is not somehow detrimental,” Geipel argues. “The real issue lies in how you allocate your attention. Listening can be just as effective as reading if you are fully focused, but multitasking while listening can compromise depth compared to immersive reading without distractions.”

Finding What Works for You

Listening alongside reading introduces yet another layer. A meta-analysis conducted by Virginia Clinton Lisell at the University of North Dakota found that while combining listening with reading might yield slight improvements in understanding, this is likely only true for those who struggle with decoding text, such as individuals with low literacy or those learning to read in a non-native language. For skilled readers, however, this dual engagement may lead to diminished comprehension due to “cognitive load theory,” where presenting information in two formats can create redundancy and overwhelm cognitive resources.

Ultimately, various factors—dyslexia, visual impairments, lengthy commutes, or personal preference—can drive the choice for audiobooks rather than print. As for whether you derive equivalent benefits, “there’s no straightforward answer,” Geipel acknowledges.

If options are available, I suggest reserving an engaging podcast or a thought-provoking book for moments of focus, rather than while preparing dinner. However, if someone is immersed in a story purely for enjoyment, as in the case of my friend’s daughter, choosing an audiobook appears to be a far better alternative than missing out altogether.

Trump Claims Rupert and Lachlan Murdoch Are Involved in Our TikTok Deal

Rupert Murdoch and his son, Lachlan Murdoch, are expected to acquire TikTok in the US, as Donald Trump mentioned during an interview on Sunday.

In an interview with Peter Doocy at Fox News’ Sunday briefing, the president was asked about the app’s sales status. Officials from the Trump administration indicated that transactions involving China-owned social media platforms are forthcoming, resulting in some confusion regarding the status of the contract.

Trump stated that moguls Larry Ellison and Michael Dell were participating in the deal, adding:

“Rupert will likely be part of the group. I believe they will join the team. They are fantastic individuals, well-known in their fields, and they are true American patriots. They care about this country, which will ensure they perform admirably.”

Part of these transactions includes Fox Corporation as one of TikTok’s investing entities. According to a report by CNN on Sunday, Rupert and Lachlan are not participating as individual investors.


Representatives from Fox, which is owned by Rupert Murdoch and led by his son Lachlan Murdoch, did not respond to a request for comment. Trump’s remarks followed his lawsuit against Rupert Murdoch’s Wall Street Journal regarding the publication revealing that he wrote crude poems and graffiti for a book edited for Jeffrey Epstein’s 50th birthday back in 2003.

In 2024, Congress enacted a law banning TikTok, owned by the China-based company ByteDance, unless it was sold to a US entity, citing national security and privacy issues. The Trump administration delayed the law and extended the deadline for the transfer multiple times. Currently, the app has approximately 170 million users in the US, and feels Trump contributed to his re-election in 2024 on Sunday.

White House Press Secretary Caroline Leavitt reported to Fox News on Saturday that six Americans will hold seats on the company’s seven-member committee, managing data and privacy through Oracle, Ellison’s firm. Leavitt indicated that the US also governs data and algorithms for American applications.

“This deal prioritizes America,” Leavitt affirmed on Saturday. “Let me clarify: this transaction ensures that TikTok is predominantly owned by Americans.”

More Britons View AI as an Economic Threat Instead of an Opportunity, Tony Blair’s Think Tank Finds

A think tank associated with Tony Blair suggests that the public perceives artificial intelligence more as an economic threat rather than a benefit.

The Tony Blair Institute cautioned that these poll findings could jeopardize Keir Starmer’s vision for the UK to become an AI “superpower,” urging the government to persuade the populace about the positive impacts of this technology.

According to a survey conducted by TBI, 38% of Britons see AI as a potential economic risk, while only 20% regard it as an opportunity. The survey, which included over 3,700 adults, also revealed that a lack of trust is the primary barrier to AI adoption.

Jakob Mökander, the director of science and technology policy at TBI, stated that the UK’s primary path to becoming an AI superpower lies in adopting cutting-edge technology. He expressed concerns that the current poll results jeopardize this aspiration.

Mökander noted, “A nation can achieve AI superpower status either by leading in development or by being a frontrunner in adoption.” He acknowledged that while the UK will not lead in development—domains dominated by the US and China—it can excel in adoption. However, he emphasized that without fostering public trust in technology, this goal is unattainable.

The UK government has identified AI as a cornerstone of its economic growth strategy, aiming for the country to become “one of the great AI superpowers” in the near future.

Nonetheless, there is considerable voter concern regarding the economic ramifications and job implications associated with AI. Entities such as TBI, the International Monetary Fund, and the Organisation for Economic Co-operation and Development predict that AI—defined as systems that can undertake tasks typically requiring human intelligence—will profoundly affect the labor market. TBI estimates that AI may lead to a shift of between 1 million and 3 million private sector jobs in the UK, although they anticipate that the total job loss will be mitigated as technology creates new positions.

Meanwhile, recruitment agencies have indicated that sectors expected to be influenced by AI, like graduate recruitment, have not yet experienced significant changes attributable to AI.

Furthermore, TBI’s polling indicates a divide between AI users and non-users, revealing that more than half of those unacquainted with the technology perceive it as a risk. In contrast, only a quarter of those who regularly use AI regard it as a threat.

Mökander stated that there is a pressing need to articulate potential benefits, like establishing AI reliability through regulations, shortening NHS wait times, and allowing individuals more family time.

Skip past newsletter promotions

Regarding the need for regulations akin to those for vaccines, Mökander emphasized educating the public and promoting positive campaigns to cultivate healthy perceptions.

The TBI has garnered significant funding from tech magnate Larry Ellison and released findings indicating the advantageous applications of AI. The report suggests measuring AI’s beneficial impact accurately and promoting responsible regulations to foster AI skill development.

A spokesperson for the UK government stated that public trust is vital for effective AI utilization and highlighted initiatives aimed at enhancing AI skills and recruitment.

“With approximately 10 million workers projected to use AI in their daily roles by 2035, it is crucial that the workforce is equipped with both the skills and confidence to engage with this technology,” the spokesperson remarked.

Strange Encounters: Exploring Chuck Tingle’s Erotic Universe with Sexy Dinosaurs, Fiery Tigers, and a Dashing Boat

In one of the regular segments of John Mulaney’s Netflix show, every week features live interactions with the comedian and his guests as they take calls on the week’s theme. This time, the topic is dinosaurs, and one caller—a surprisingly enthusiastic young boy and noted paleontologist—introduces himself as Chuck, among others. He discusses his book, Dinosaur erotica. “I think that’s my most recognized and award-winning book,” he elaborates. “It was nominated for the Hugo Prize.”

Actor Ayo Edebiri, one of Mulaney’s guests, inquires whether he won. “I didn’t win, but I went on to write a book called Pound after my Hugo Prize loss.”

Edebiri and fellow guest Conan O’Brien react with a mix of delight and confusion, but the call wraps up before Mulaney can delve into the comedic possibilities of their discussion.

Mulaney’s fans, often a quirky and socially active group, rushed to the comments, expressing that he missed a golden opportunity. The eccentricity isn’t just a relic of the internet’s past; it’s exemplified by the Elite class figure, Chuck Tingle. He initially went viral thanks to his uniquely self-published erotica, complete with endearingly bizarre Photoshop covers and titles that seem as if they were slapped together by an alluring Velociraptor. Tingle’s work even earned a Hugo Award nomination from the far-right Cultural War fringes.


He has consistently shared cover after cover on Twitter, producing increasingly elaborate titles that incorporate creatures of myth. From the absurd (Open wide for a handsome Sabertooth dentist who is also a ghost) to philosophical musings (I became gay by existential horror that I could actually be a character in a Chuck Tingle book), topical references (I have released this handsome cargo ship from the Suez Canal and now he is stuck on my ass), and recursive metatextual adventures (being slapped on the backside in his book “Spanked by My Own Ass”), Tingle’s work is truly multi-layered (with at least six such layered concepts).

If these titles sound outrageous, take a trip through your favorite ebook store to remind yourself that romance and erotica can be surprisingly utilitarian in their own right.

To date, Tingle has released “Tingle’s Gone Legate,” novellas, and three mainstream horror novels throughout the years.

He has also begun appearing in person at fan events and conventions. Similar to the enigmatic author Elena Ferrante, whose audience largely enjoys indie horror video games, Tingle maintains his anonymity. However, unlike Ferrante, he flamboyantly showcases himself with a pink pillowcase and a bag over his head, obscuring his features while exuberantly declaring his mantra, “love is real.” Sporting a colorful ensemble of a big blazer, sequined shorts, band tees, and sometimes light-up sneakers, he energetically dashes through theaters and bookstores.


Online, Tingle engages with his audience and celebrates his work with an innocent earnestness, using a unique mix of whimsical language that falls between highbrow and fandom lingo. He refers to readers, fans, and curious onlookers as “Bakaroo.” Life experiences, stories, beliefs, and careers are his “trot.” Tingle notes that his Orbit Bakarus never truly die but are merely visiting and riding a “lonely train” of existence. He expresses thoughts on the “existential dread of choking” and the notion that love is real—whether in eroticism or existentialism, his stories affirm this principle.

Tingle has openly discussed his sexuality and sexual experiences in relation to neurodivergence. His storytelling often reflects his experiences being queer, depicting characters who navigate the challenges of revealing their true selves to family and friends in small-town America. His recent horror novels are set in a shared universe, intertwining narratives like Camp Damascus and Bury Your Gays, exploring themes of capitalism, chaos, and radical acceptance as monstrous forces. He emphasizes that authenticity in love and experience is paramount.

This approach is unabashedly direct. To borrow a line from The Great Garth Marengi, I know of writers who employ subtext—yet they all seem rather unwell.

The physical mask Tingle described serves to allow his true self to shine through, as it means less effort concealing his autism. He has maintained a colorful career persona, hinting at the possibility of a performance artist or character he has created since he was young. Rumors abound that he is, in fact, a well-known sturdy actor (and one of the most likable Hollywood Chrises) named Chris Pine.

However, most ardent Bakarus recognize that Chuck leads his own trot.

The Only Earth Creatures Capable of Surviving on Mars

Mars is a quite an intimidating environment for life forms accustomed to Earth. The average surface temperature hovers around -63°C (-81°F), and temperatures only manage to rise slightly above freezing near the equator during summer.

Moreover, the atmospheric pressure is equivalent to that found on Earth at an altitude of 35km (almost 115,000 feet), well above the cruising altitude of commercial flights. This sparse atmosphere is predominantly carbon dioxide, containing only minimal amounts of oxygen.

Additionally, liquid water is virtually nonexistent on Mars, with radiation levels being 400 times greater than those on Earth, and only rare instances of extremely saline trickles.

Nonetheless, certain Earth organisms have shown a remarkable ability to endure such harsh conditions.

The European Space Agency conducted a series of experiments between 2008 and 2016, exposing various organisms and seeds to simulated Martian conditions aboard the International Space Station.

Tardigrades, fungi, and some bacteria survived for over a year, but solely in dormant forms, such as spores and cysts.

Some lichens and algae went a step further, demonstrating actual metabolic activity when partially shielded from radiation—this could occur on Mars if they are embedded in soil or hidden within rock crevices.

In 2024, Chinese researchers discovered that various desert moss species (Syntrichia caninervis) could endure simulated Martian conditions. However, “tolerance” is far from thriving in such an environment.

Although the moss was able to recover after a week in the simulated Martian environment and returned to normal growth, researchers did not find evidence of metabolic activity, such as oxygen production, within the Martian setting.

But the challenges are even greater.

Mars has an average surface temperature of -63°C (-81°F) and an atmospheric pressure that corresponds to 35km (nearly 115,000 feet), along with radiation levels that are 400 times higher than on Earth.

Mars soil contains perchlorate, a problematic oxidizer that is toxic to cell functions and leads to DNA damage. Exposure to the ultraviolet radiation prevalent on Mars makes it even more reactive.

The Chinese experiments did not simulate perchlorate presence in the Martian environment. Had it been included, it likely would have obliterated the moss entirely.

Some fungi survive perchlorate, and several bacterial species can utilize it as an energy source, even breaking it down into harmless by-products. However, these species still require water and warmth to thrive.

Typically, when we store items, we employ various methods to eliminate bacteria and fungi or inhibit their growth.

We freeze food, dehydrate it, sterilize with UV light, soak it in saline solutions, or seal it in oxygen-removing containers. On Mars, all these methods are naturally enforced!

If we aimed to sterilize a planet, we could hardly surpass the existing conditions on Mars.


This article addresses the inquiry posed by Robin Mason of Manchester: “Is there anything on Earth that can withstand Martian conditions?”

Ofcom’s Call to Action: Ensuring Porn Sites Comply with Online Safety Regulations

TThe Ofcom regulators, equipped with clipboards, navigated the exhibition space during the International Adult Industry Conference in Prague over the weekend, aiming to motivate 1,700 attendees to adhere to the UK’s newly implemented online safety regulations.

“Be truthful,” a regulator addressed a crowd of porn site operators and staff during a midday seminar discussing the age verification requirements that were set in motion in July as part of the legislative framework for accessing adult content. “Be transparent. If your efforts fall short, include them in the risk assessment.”

Attendees enjoying complimentary champagne offered by conference sponsors posed some uneasy inquiries. What steps should a company take if it lacks the funds for age verification? How hefty are the penalties? Can a site circumvent regulations by blocking traffic from the UK? Were Ofcom officials aware that some site owners might be trying to undermine their competitors by reporting them for non-compliance?

“We are here to assist you,” another Ofcom regulator explained to an audience of around 50 men and seven women. “It’s a challenge. There’s a wealth of information to absorb, but we exist to assist members of the adult industry in achieving compliance.”

Seven weeks following the activation of the online safety law, Ofcom officials seek to portray the adult industry’s response to this legislation in a positive light. They noted that most of the leading 10 and top 100 adult websites have either implemented age verification checks or restricted access within the UK. Platforms like X and Reddit, which feature pornographic content, also provide age verification guarantees. In August, views surged to 7.5 million on the top five age verification websites, up from 1 million in June.

Regulators intend to frame the introduction of age verification on July 27 as a pivotal moment for the industry, dubbing it “AV Day,” when children’s access to British porn would be unequivocally obstructed. The situation, however, is more nuanced.

In the days following the law’s enactment, there was a notable spike in VPN downloads, enabling users to disguise their locations and bypass age verification prompts.

“This development was quite unfortunate,” commented Mike Stabile, director of public policy for the Free Speech Coalition, representing American adult entertainment. He mentioned moving to a location that did not comply and opted for a non-compliant site. “VPN usage has surged. People are not compliant. Traffic is redirecting to piracy sites. I don’t think Ofcom will regard this outcome as what they intended.”

Corey Silverstein, an American attorney representing several companies in the adult industry and who has encountered numerous failed attempts at enforcing age verification laws in the U.S., noted a significant skepticism towards regulators. “While people maintain professionalism and politeness, this is not the most agreeable audience. Some display overt disdain. You can sense the discomfort in participating in an event like this.”

Despite this, he delivered a presentation for site owners, advising them to confront their aversion to regulators and collaborate with Ofcom to implement new guidelines.

“Their intent is not to harm your business. They are quite friendly. They aren’t out to eliminate you,” he stated. “As I understand it, they do not even impose financial fines. Their goal is to guide you towards compliance.”

Ofcom officials were dressed in neatly pressed white shirts, working amid the ambient sounds of steel drums, distributing A4 printed questionnaires while sponsors served cocktails and a troupe of feather-clad dancers entertained attendees.

The paper form, which allowed for anonymous responses, requested representatives to indicate whether they had adopted age verification in the UK and to discuss reasons for inaction regarding non-compliant businesses. By Saturday evening, Ofcom officials noted that an insufficient number of representatives had completed the form but remained hopeful for better participation on Sunday.

Though no fines have yet been issued under the Online Safety Act, Ofcom has initiated 12 investigations into over 60 porn services, including websites and applications.

Skip past newsletter promotions

Updates from these investigations have fueled discontent among adult site proprietors, who are also advocating for stricter regulations in the U.S. and France. Yet, there was some begrudging acknowledgment of Ofcom’s effort to engage with the industry in events and dialogues.

“In the U.S., regulatory bodies often shy away from engaging with us,” remarked Alex Kekeshi, vice president of PornHub’s brand and community. “I appreciate Ofcom’s invitation to the table. Such engagement is often overlooked in discussions on industry regulations.”

Before July 27, Ofcom established a specialized porn portfolio team consisting of six compliance officers to encourage businesses to meet regulatory standards. These team members requested anonymity due to conservative reasons but participated in similar discussions in Berlin, Amsterdam, and LA. Additionally, a larger team of over 40 staff members is focused on investigating organizations that fail to comply.

“We are acutely aware of the industry’s scale and the ease of establishing services for distributing pornographic content indiscriminately,” one regulator remarked. “We are not claiming to lead every service towards compliance; our strategy is to allocate resources where children face the highest risk of harm.” When penalties are applied, they are designed with a deterrent effect, potentially reaching up to £18 million or 10% of global revenue.

“Companies can opt not to risk being pursued by us or facing penalties. We aim to shift the incentive balance so that compliance is deemed less risky.”

Another Ofcom representative avoided commenting on the increase in VPN downloads, asserting that the law’s purpose is to prevent children from inadvertently encountering pornographic content (rather than going after those who deliberately seek it).

In their bid to comply with the new age verification requirements, site owners are also addressing the challenges posed by AI-generated content, urging users to engage of Ofcom’s attention and seeking to prevent companies like Visa and MasterCard from processing payments linked to violent and illegal content. Sites and applications featuring AI-generated pornography also fall under the scope of this legislation.

“How can we distinguish between a 15-year-old AI model and one that represents an 18- or 19-year-old within compliance frameworks?” one attendee questioned, expressing concerns about the potential for AI to inadvertently generate child sexual abuse material.

Steve Jones, who operates an AI porn site, stressed that AI systems need to be programmed to acknowledge what is deemed inappropriate. “We must ensure that depictions are not too youthful or flat. We will disallow pigtails, braces, and toys typically associated with children,” he stated. “AI lacks the ability to differentiate between youthful-looking adults and minors. It’s crucial to teach these distinctions.”

Mars’ Mysterious Markings: The ‘Most Obvious Signs’ of Alien Life, According to NASA

The unusual “leopard spot” markings on Mars’ rocks might finally indicate that alien microbes could have existed on the Red Planet.

A comprehensive analysis of these rocks has shown that the intricate patterns are “the clearest signs ever found on Mars,” as stated by Sean Duffy, a NASA representative.

These rocks, estimated to be about 3.5 billion years old, were discovered in July 2024 by NASA’s Perseverance rover. Since then, planetary scientists have been exploring various hypotheses to explain these markings.

Recent information from a Nature paper suggests that while the patterns may have a geological origin, the prevailing theory now points toward ancient Martian microbes as the likely culprits.

Perseverance collected rock samples, hoping to yield a more definitive answer. If all goes well, these samples will eventually return to Earth for a thorough examination of potential signs of past life.

Leopard Spots on Bright Angel

Currently, Mars is a barren, lifeless world, but this hasn’t always been the case. Until around 3 billion years ago, Mars’ surface was rich with flowing rivers and expansive lakes.

Wherever there is water on Earth, signs of life typically follow. For two decades, NASA’s rovers have been scouring Mars for evidence suggesting that the Red Planet could have once supported life.

The Perseverance rover is exploring a site known as Jezero Crater, which was a lake in Mars’ ancient history. Similar environments on Earth often serve as habitats for microorganisms.

Within rock formations referred to as the Bright Angel formation, Perseverance uncovered stunning patterns resembling leopard spots.

“We conducted extensive observations of the entire rock formation at Bright Angel,” said Professor Joel Hurowitz of Stony Brook University in the US, in an interview with BBC Science Focus.

While Perseverance’s cameras captured detailed images of the patterns, a spectrometer analyzed the mineral composition. The rover even utilized radar to map the structure of the subsurface outcrop.

“Essentially, we used every tool available on these rocks except for the kitchen sink,” Hurowitz remarked.

The analysis indicated that the patterns were formed by iron-rich minerals called vivianite and greygite. On Earth, these minerals typically arise from “redox reactions,” a process in which microorganisms exchange electrons with their environment.

“On Earth, these reactions are often facilitated by microorganisms residing in sediments, which derive energy from them for metabolic activity,” Hurowitz explained. The residuals from these processes create distinctive patterns in sedimentary rocks.

However, this doesn’t mean we should rush to celebrate the discovery of alien life just yet. There are other mechanisms that could account for the leopard spot patterns without any biological influence.

For instance, heat could have driven reactions between mud and organic matter, resulting in new minerals.

Yet, the research team did not find evidence indicating that the rocks were subjected to heat. Additionally, other methods they investigated also did not seem viable. Nonetheless, Hurowitz cautioned, “We cannot dismiss these entirely.”

One of the most surprising findings is the relatively young age of these rocks. At only 3.5 billion years old, the patterns formed while Mars was already entering a phase of decline, suggesting that the planet may have been habitable for much longer than previously assumed.

Unfortunately, Perseverance has an entire planet to explore and we continue our quest to find life beyond Earth.

“If I could revisit Jezero in the future, I would have follow-up questions that I would like to address using the rover’s instruments,” Hurowitz remarked.

“However, these follow-up analyses may not necessarily provide a more conclusive answer regarding whether these features were shaped by life.”

“Ultimately, determining whether life was involved will necessitate laboratory analysis back on Earth.”

Bringing Mars to Earth

Fortunately, Perseverance is part of the initial phase of Mars’ sample return mission. Not only is it studying the rocks on Mars, but it’s also preparing to bring samples back to Earth.

Before departing from Bright Angel, the rover collected and stored samples from the rocks along with numerous similar fragments obtained during its mission on Mars.

NASA aims to collaborate with the European Space Agency on follow-up missions to retrieve these samples and return them to Earth where they can be analyzed in top-tier laboratories.

After 3.5 billion years, finding definitive evidence is challenging. Instead, researchers will seek additional signs that microbes may have left behind.

“The first logical step is to analyze the isotopic composition of iron, sulfur, and carbon in the various mineral and organic components of the rock,” Hurowitz stated.

Isotopes can be thought of as different variants of the same element. Microorganisms tend to retain particular isotopes more than their non-biological counterparts, enabling researchers to narrow down their search for evidence of life.

“These variations in isotopic composition are essential tools for investigating biological signals in ancient rocks on Earth, and we aim to apply similar methods to this Martian sample,” Hurowitz noted.

The return mission is tentatively scheduled for the 2030s, although there is a risk of cancellation due to cuts to NASA’s planetary exploration budget during the Trump administration.

“NASA is examining strategies for retrieving these samples and others,” a NASA spokesperson told BBC Science Focus. “Having explored Mars for 60 years, we will continue to look into budgetary and timing considerations for a quick and cost-effective return of these samples.”

“We hope these findings will further motivate the sample return mission,” Hurowitz added. “This will allow us to scrutinize the sample with the detail necessary to determine its historical record of life on Mars.”

“If it’s indeed life, that would suggest our planet is not the only one where life has evolved,” Frowitz concluded. “If life originated twice, how many other places might it have occurred?”

Rise of AI Chatbot Sites Featuring Child Sexual Abuse Imagery Sparks Concerns Over Misuse

A chatbot platform featuring explicit scenarios involving preteen characters in illegal abuse images has raised significant concerns over the potential misuse of artificial intelligence.

A report from the Child Safety Monitoring Agency urged the UK government to establish safety guidelines for AI companies in light of an increase in technology-generated child sexual abuse materials (CSAM).

The Internet Watch Foundation (IWF) reported that they were alerted by chatbot sites offering various scenarios, including “child prostitutes in hotels,” “wife engaging in sexual acts with children while on vacation,” and “children and teachers together after school.”

In certain instances, the IWF noted that clicking the chatbot icon led to full-screen representations of child sexual abuse images, serving as a background for subsequent interactions between the bot and the user.

The IWF discovered 17 images created by AI that appeared realistic enough to be classified as child sex abuse material under the Child Protection Act.

Users of unnamed sites for security reasons also had the capability to generate additional images resembling the illegal content already accessible.

Operating from the UK and possessing global authority to monitor child sexual exploitation, the IWF stated that future AI regulations should incorporate child protection guidelines from the outset.

The government has revealed plans for AI legislation that is anticipated to concentrate on the future advancement of cutting-edge models, prohibiting the ownership and distribution of models that produce child sexual abuse in crime and police bills.

“We welcome the UK government’s initiative to combat AI-generated images and videos of child sexual abuse, along with the tools to create them. While new criminal offenses related to these issues will not be implemented immediately, it is critical to expedite this process,”

stated Chris Sherwood, Chief Executive Officer of NSPCC, as the charity emphasized the need for guidelines.

User-generated chatbots fall under the UK’s online safety regulations, which allow for substantial fines for non-compliance. The IWF indicated that the sexual abuse chatbot was created by users and site developers.

Ofcom, the UK regulator responsible for enforcing the law, remarked, “Combating child sexual exploitation and abuse remains a top priority, and online service providers failing to implement necessary safeguards should be prepared for enforcement actions.”

The IWF reported a staggering 400% rise in AI-generated abuse material reports in the first half of this year compared to the same timeframe last year, attributing this surge to advancements in technology.

While the chatbot content is accessible from the UK, it is hosted on a U.S. server and has been reported to the National Center for Missing and Exploited Children (NCMEC), the U.S. equivalent of the IWF. NCMEC stated that the report on the Cyber Tipline has been forwarded to law enforcement. The IWF mentioned that the site appears to be operated by a company based in China.

The IWF noted that some chatbot scenarios included an 8-year-old girl trapped in an adult’s basement and a preteen homeless girl being invited to a stranger’s home. In these scenarios, the chatbot presented itself as the girl while the user portrayed an adult.

IWF analysts reported accessing explicit chatbots through links in social media ads that directed users to sections containing illegal material. Other areas of the site offered legal chatbots and non-sexual scenarios.

According to the IWF, one chatbot that displayed CSAM images revealed in an interaction that it was designed to mimic preteen behavior. In contrast, other chatbots not showing CSAM indicated that they were neither dressed nor suppressed when inquiries were made by analysts.

The site recorded tens of thousands of visits, including 60,000 in July alone.

A spokesperson for the UK government stated, “UK law is explicit: creating, owning, or distributing images of child sexual abuse, including AI-generated content, is illegal… We recognize thatmore needs to be done. The government will utilize all available resources to confront this appalling crime.”

MetaExpose Authors Risk Bankruptcy Following Company Criticism Ban | Meta

The former Meta executive, who authored a provocative book highlighting social media companies’ interactions with China and their treatment of teenagers, is reportedly facing bankruptcy after its release.

Lawmakers in Congress have contended that Mark Zuckerberg’s company is trying to “silence and punish” Sarah Wynn Williams, the former director of global public policy at Facebook, Meta’s predecessor.

Former Labor Transport Secretary Louise Hayes stated that Wynn Williams may incur a fine of $50,000 (£37,000) for each breach of an order obtained by Meta.


In her book, Eardaling People, published this year, Wynn-Williams made several claims regarding the conduct and culture of social media firms, including allegations of sexual harassment that the company denied. She asserts that her dismissal was due to “poor performance and toxic behavior.”

Nevertheless, the former diplomat has been prohibited from publishing memoirs after Meta secured a ruling against her. She later testified before the US Senate Judiciary Subcommittee, claiming Meta collaborated “with gloves” with Beijing regarding censorship tools.

Pan Macmillan, which published the memoir, reported over 150,000 copies sold across all formats. The book was also recognized as a Sunday Times bestseller in Hardback for 2025, with a paperback edition due for release early next year.

Haigh pointed out Wynn-Williams’ situation during a House of Representatives debate on employment rights on Monday, asserting that her decision has led to significant financial jeopardy.

“Despite previous official statements indicating that Meta had ceased using NDAs [non-disclosure agreements] in cases of sexual harassment,” she noted, “Sarah is being pushed towards financial ruin within the UK arbitration system.

“Meta has given Sarah a disturbing order and is gearing up to impose a $50,000 fine for any violations. She is on the brink of bankruptcy, and I am confident that the home and government will push this legislation to protect individuals with moral courage.”

It’s understood that the $50,000 figure pertains to damages Wynn-Williams must pay for violating a separation agreement she signed when leaving Meta in 2017, with Meta asserting that she voluntarily agreed to the terms.

Mehta indicated that, as of now, Wynn-Williams has not been compelled to adhere to the contract.

The company refrained from commenting on Hayes’ intervention. Senate testimony from Wynn-Williams previously asserted that the company has been “disconnected from reality” and is plagued by false claims.

Meta characterized the book as “an outdated, previously reported compilation of company claims and unfounded allegations against executives.” She claimed she was dismissed for “poor performance and toxic behavior,” with investigations concluding that she made misleading harassment allegations.

The ruling that barred her memoir’s publication affirmed that “the false narrative should never have seen the light of day.”

The order dictated that Wynn-Williams must halt promotion of the book and minimize any further publications, though no actions were mandated against Pan Macmillan.

Since her Senate hearing in April, Wynn-Williams has remained publicly silent. In a statement this month, she expressed gratitude for the continued investigation into Meta’s actions by the US Senate.

“I wish I could elaborate,” she stated. “I urge other tech employees and potential whistleblowers to share their insights before more harm comes to children.”

Her attorney mentioned that Wynn-Williams “will remain silent regarding the matters currently under Congressional investigation.”

Five Incredible Inventions that Turn Humans into True Cyborgs

We already understand how to artificially bring our bodies back to their natural optimal state. Prescription glasses can help correct vision, while hearing aids aid those with hearing loss.

Today, emerging technologies are advancing to enhance the human body more than ever before.

Those who utilize these innovations embody a blend of human and machine, elevating their capabilities to reach what once seemed unattainable.

These are not merely futuristic concepts; they are new technologies available on the market or soon to be released.

I’ll take you to the sky

Flight has been a long-held human aspiration, from Icarus in Greek mythology to flying cars in sci-fi films like Blade Runner. Though personal flight technology may seem fanciful, it exists today in the form of a gravity jet suit.

We once envisioned rocket boots that could lift us off the ground, but such designs would be inherently unstable due to thrust being directed away from the wearer’s center of gravity.

Instead, the Gravity Jetsuit employs five engines that gently assist the wearer in navigating the air. Pilots can hover, spin, and even glide short distances above land or water.

The 1,050 horsepower gas turbine on the back provides essential lift, while two small jet turbines on each arm ensure stability and control.

In 2021, the Royal Navy tested the suit in a training exercise to explore its onboarding potential.

Human vision is relatively limited; without light, we are nearly blind. Night vision goggles have allowed us to see red light wavelengths for some time, but this technology has now been miniaturized.

Chinese scientist developed contact lenses coated with nanoparticles that absorb infrared rays and re-emitt them as visible red, green, or blue light.

In trials, these lenses enabled users to see flashes from an infrared LED.

Interestingly, participants found it easier to see these flashes with their eyes closed, as the visible interference from light was blocked by their eyelids.

In the future, this technology may be adapted to assist those with color blindness in experiencing a wider range of colors.

I’m walking towards the future

Exoskeleton suits are wearable machines designed to enhance natural strength. Think of them as a type of powered suit or wearable forklift.

Many associate them with sci-fi movies like Alien, but they are already in use today.

Exoskeleton sensors detect the wearer’s movement and activate joint motors to provide additional strength.

Exoskeleton technology currently assists some individuals with disabilities, enabling them to function without assistance. It is also being developed to help warehouse workers lift and move heavier objects safely.

Moreover, this technology has everyday applications, such as aiding individuals in hiking longer distances or navigating stairs that might otherwise be challenging.

Get a better grip

Scientists at University College London recently created a glove-like device that provides the wearer with an additional thumb.

While this may appear redundant (as most of us already possess two), tests show that the additional thumb enhances dexterity, allowing tasks to be completed more easily with two hands.

Sensors located beneath the wearer’s toe control the movement of the third thumb. Currently, there is no tactile feedback, meaning the wearer cannot yet use it for delicate tasks, like carrying eggs.

Though the third thumb is not part of our natural anatomy, participants have quickly adapted to using it; only four out of nearly 600 individuals could not operate it successfully.

Control things with your thoughts

Brain Control Interface (BCI) is an innovative technology that enables individuals to control computers using their thoughts.

By embedding microelectrodes into the brain, nerve signals associated with limb movement can be decoded by computers and used to manipulate external devices.

This technology enhances far more than just computer usability; it offers those with neurodegenerative conditions reliable control over their environment.

So far, this technology has allowed volunteers with spinal cord injuries to control computer cursors merely by thinking of movements associated with their paralyzed hands or arms.

The next evolution for these devices is the precise control of robotic limbs. With BCI technology, scientists envision a future where patients with muscle atrophy or other degenerative conditions fully regain their motor capabilities.

Experts Caution Against Earlier and Shorter Seasons

This autumn, New England’s renowned leaf spectacle may not extend as long as Leaf Peepers hope. Following a summer marked by drought and fluctuating rainfall, experts anticipate that colors will emerge early, shine brightly, and fade more quickly than usual.

Timing is not just essential for Instagram-worthy shots. Annually, millions flock to New York, Vermont, Massachusetts, New Hampshire, and Maine to hike, drive, and explore under the vibrant canopy, contributing an estimated $8 billion to the local economy, according to the US Forest Service.

However, this year, scientists say the iconic display is less predictable, with sporadic bursts of color replacing the usual weeks of vibrant waves of red, orange, and gold.

“Bright, Short, Early” season

Jim Salge, an autumn leaves predictor for Yankee magazine, forecasts the transition to be “bright, short, and fast.” Some leaves have already turned brown before showcasing their vibrant hues.

“Traditionally, we observe changes moving northward, inland, and in coastal areas, but as trees become stressed and change rapidly, we expect to see more patchwork patterns this year,” Sarji noted.

When trees do not receive adequate water, they become “stressed,” impairing the process of photosynthesis, which converts sunlight into energy. Conversely, excessive water can suffocate roots.

For optimal viewing, I suggest heading to the western parts of Maine, southern New Hampshire, and northern Massachusetts, as well as the White Mountains in Vermont.

Peak colors are expected to shift to Vermont, New Hampshire, and Western Maine by early October, with higher elevations predicted to peak about a week earlier than usual.

“The silver lining about New England is that if you miss it, you can always head further south,” he said. “If it’s too early, go north or ascend to the mountains.”

Travelers can keep track of leaf changes with tools like the Peak leaf map by Yankee Magazine and I Love New York’s weekly reports.

Why are the leaves changing?

Nonetheless, climate change has generally intensified over recent decades, and this year’s dry summer has accelerated the timeline.

“Ideally, our forests would benefit from a mild rain event evenly spread throughout the year,” explained Mukundrao, assistant professor at Columbia University’s Lamont-Doherty Earth Observatory. “However, a series of extreme storms, followed by dry spells, makes it too rapid for the soil to absorb the water.”

Vibrant leaf colors thrive on warm days and cool nights, but stressful conditions for trees can hasten leaf drop. Stressed or unhealthy trees often exhibit shorter transitions and dull foliage, Rao mentioned. In contrast, urban trees typically retain color longer, as buildings and pavement hold heat while streetlights provide extra illumination.

Additional threats include fungal diseases from heavy spring rains and diseases affecting beech trees.

“We are witnessing invasive insects altering forests and decimating various tree species, alongside invasive plants disrupting native growth and patterns,” Sarji stated.

Tracking changes

To make predictions, Salge depends on weather forecasts and phenotype data, which involves tracking seasonal life cycles.

Notably, Polly’s Pancake Parlor in Sugar Hill, New Hampshire, has been monitoring local foliage since 1975. Records indicate that peak colors appeared for two weeks in late September that year; however, in 2024, it shifted to just two days in early October.

The US National Phenology Network gathers and shares observations from across the country. Its Nature’s Notebook app invites volunteers to document seasonal changes, bolstering over 200 scientific studies, according to director Theresa Crimmins.

“We have a general understanding of nature,” Crimmins remarked. “However, when focusing on specific species in particular locations, there remains much we do not comprehend.”

The revamped version of the app, launching this spring, allows users to upload photos for even one-time observations.

“More people can now become citizen scientists,” Sarji commented. “Their perspectives on the world contribute valuable data.”

The Roborock Saros 10 takes care of all your floor cleaning needs. It’s not merely a vacuum and mop; it empties its own dust bin and cleans its mop, allowing for weeks of hassle-free operation. With a tangle-free brush, vibrating warm water mop, and unmatched suction power, your floors will be sparkling clean.

Setting it up goes beyond just plugging it in and connecting it to your phone. Initially, you’ll take it around your home to map the floor plan, and when it transitions onto carpet, you can keep the mopping pad docked or store it automatically.

The only manual tasks required are filling the clean water tank, emptying the dirty water tank, and replacing the large dock dust bin when necessary. Depending on your home’s size and dirtiness, you’ll typically need to address the aquarium weekly, while the dust bin can go months before needing a change.

Though it’s the priciest item on this list, for those with a busy lifestyle, it’s worth every cent.

It seems like everyone in the neighborhood has a Ring Video Doorbell— and with good reason. They offer utilities that you might not realize until you own one. Do you need to monitor package deliveries when away? Want to communicate with your pets while you’re out? Looking to capture amusing videos for social media? The Ring doorbell is versatile.

I personally have an older model (the Wired Doorbell Plus) that has treated me well for four years, and the newest models, like the Wired Doorbell Pro, appear even better. All of them provide motion alerts to your smartphone whenever movement is detected, notifying you of doorbell rings and allowing you to converse with guests via two-way audio without opening the door.

If you have existing doorbell wiring, the entry-level Video Doorbell Wired meets most needs; Battery Doorbell Pro and Wired Doorbell Pro offer additional wireless convenience and enhanced video quality.

If you’re hesitant about subscribing for video storage, consider Eufy C210, which stores video locally, eliminating subscription requirements.

Be cautious of becoming overly reliant on the video doorbell’s features.

Implications of Trump’s Space Strategy for Future Mars Missions

Since January 2025, when Donald Trump returned to the White House, his administration has enacted severe funding cuts across various federal agencies, including NASA. The proposed 2026 Budget plans to decrease NASA’s institutional funding by as much as 24.3%.

This translates to a financial drop from $24.8 billion (£18.4 billion) allocated by Congress in 2025, to $18.8 billion (£13.9 billion) in 2026.

The president’s proposals are not law until they pass through Congress, where they will be scrutinized, debated, and revised in the coming months.

Nonetheless, this situation focuses attention on some key priorities Trump has outlined during his two terms in office.

Focus on Human Spaceflight

During Trump’s first term from 2017 to 2021, NASA’s budget increased from $19.5 billion (£15.5 billion) to $23.3 billion (£18.5 billion), which constitutes about 0.48% of federal spending.

Trump has reinstated the National Space Council, shaping US space policies with the US Space Force consolidating national security assets in the latest military setup.

His administration emphasizes human spaceflight, launching NASA’s Artemis program aimed at returning humans to the moon by 2024.

Although this timeline appears overly ambitious, Artemis II is still scheduled for a crewed mission around the moon in 2026. If all goes well, Artemis III may land on the lunar surface a few years later.

Near the close of his first term, Trump formalized the National Space Policy, committing to lunar exploration and future missions to Mars. This policy streamlined regulatory frameworks, increasing accessibility for the private sector.

Support for human spaceflight and exploration carried on into his second term.

In April, when announcing the NASA Budget, the White House asserted its intention to return American astronauts to the moon “before China,” which has ambitious plans for a lunar base by the 2030s.

“The proposal includes investments to pursue lunar and Mars exploration simultaneously but prioritizes vital science and technology research,” stated NASA Administrator Janet Petro, reinforcing that the agency would “continue to progress towards achieving the impossible.”

Risk Projects Due to Budget Cuts

However, the budget cuts may hinder NASA’s ability to meet its goals, as it calls for “rationalizing the institutional workforce” while cutting many support services, including IT and maintenance.

The budget suggests cancelling the costly and delayed Space Launch System (SLS) rocket and the Orion Crew Capsule, both essential for long-range space missions like Artemis.

Instead, it proposes replacing them with “a more cost-effective commercial system” to facilitate subsequent missions.

According to the White House, SLS is operating at 140% over budget, costing $4 billion (£3.2 billion) per launch.

The SLS rocket completed an unmanned Artemis I mission in 2022, but as Trump’s budget advances, Artemis II will send astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen around the moon in 2026, with plans for lunar landings to follow.

Eliminating SLS and Orion, referred to as the “Legacy Human Exploration System” in Trump’s budget, could save $879 million (£698.5 million).

However, US lawmakers have expressed concerns about terminating the program, despite its notable expenses, as it has taken a decade to prepare for the flight, and cancellation could grant China a competitive advantage.

This sentiment was echoed by Texas Senator Ted Cruz: “It’s hard to think of more devastating mistakes,” he remarked during an April Senate hearing.

Another project earmarked for termination is the Lunar Gateway, a new space station intended to orbit the moon. Key hardware for this initiative has already been constructed in the US, Europe, Canada, and Japan.

While some missions might be salvaged, these cancellations risk alienating international partners that NASA has built relations with over decades.

Is There No More NASA Science?

The budget also threatens significant cuts to NASA’s Earth and Space Science Programs, with funding for the former at £1.16 billion (£921.7 million) and the latter at £2.655 billion (£2.1 billion).

“Are Mars and Venus habitable? How many Earth-like planets exist? We’re opting not to find out; such questions will remain unanswered,” the critique suggests.

The budget aims to terminate “multiple, affordable missions,” including long-term endeavors like the Mars Sample Return (MSR), which was deemed unsustainable.

This mission aims to uncover significant information about Mars’ past by analyzing rock and soil samples already collected by rovers currently exploring the planet.

Nonetheless, NASA acknowledged last year that the estimated cost of the MSR mission ballooned from $7 billion (£5.6 billion) to $11 billion (£8.7 billion), with its timeline pushed back from 2033 to 2040.

The proposed budget suggests that MSR goals may be achieved through crewed missions to Mars, aligning with Trump’s promise to “send American astronauts to plant the stars and stripes on Mars.”

However, China’s plans for a Mars sample return mission remain robust, with aspirations for execution in 2028, potentially prompting Congressional pushback against the MSR budget cancellation.

In Earth Sciences, the budget proposes cuts to various Earth monitoring satellites, many vital for tracking climate change.

The future of NASA’s Landsat Next is in question, which includes a trio of satellites set to launch in 2031 for monitoring Earth’s dynamic landscapes.

Meanwhile, several climate satellites and instruments currently operational, such as orbital carbon observatories and deep-sea climate stations, face closures even though they remain fully functional.

Another mission facing uncertainty is the Nancy Grace Roman Space Telescope, scheduled for launch between 2026 and 2027, aimed at planetary exploration and investigating cosmic evolution.

This initiative is expected to be pivotal in understanding dark matter, dark energy, and answering fundamental questions about the universe.

Though Roman’s costs have escalated from an initial $2 billion (£1.6 billion) to over $3.2 billion (£2.5 billion), with 90% of the projected expenditure already incurred, the budget proposes reducing its development funding by $244 million (£133.9 million).

Ultimately, it remains unclear how the budget will be finalized as it awaits Congressional approval. Will these cuts devastate scientific progress, or usher in a new era of human exploration?

Outrage from Parents: Meta Features Female Students’ Photos in Ads Aimed at Men

Meta has sparked controversy by utilizing a female student’s back-to-school photo to market one of its social media platforms to a 37-year-old man, a decision deemed “outrageous” and “upsetting.”

The man is pitted against Mark Zuckerberg’s Elon Musk’s X, receiving a post urging him to “get the thread.”

Meta employed the child’s images after they were shared on Instagram by their parents as school started back up. The parents were unaware that the meta setting allowed for this usage. One mother noted her account was private, yet the posts were automatically visible in public threads. Another mother mentioned that she posted the photo on her public Instagram account. Stranger interactions highlighted their child’s posts as “suggested threads.”

The recipient conveyed to the Guardian that the post felt “deliberately provocative and ultimately exploitative of the children and families involved.”

The father of the13-year-old girl featured in the post expressed that it was “absolutely outrageous.” All images portrayed female students in short skirts, showcasing bare legs or stockings.

“Discovering her image used by such a large company in a context that felt sexualized for product promotion made me feel quite sick,” he stated.

Meta, a massive company valued at £1.5TN, based in Menlo Park, California, defended its actions, stating the images did not breach their policies. They encouraged users to explore the thread by highlighting public posts that adhere to community standards and recommended guidelines. Although their system does not recommend threads shared by teenagers, these posts were generated from adult accounts that permitted public viewing.

The man who received the post noted that he was solely sent promotional content featuring female students, with no representation of boys in school uniforms, which he felt added a “sexualization aspect.”

One mother of a 15-year-old said the images were used in a promotional post featuring a prominent “thread” button. “It was a photo of my daughter heading to school. I never anticipated Instagram would utilize it for promotion. I absolutely hate it. She’s a minor,” she lamented.

She firmly rejected any agreement, stating, “It wasn’t for the money of the world. [its platform].”

Her Instagram account, typically modest with 267 followers, saw her child’s post attract nearly 7,000 viewers.

Another mother whose 13-year-old child’s photo was similarly featured remarked:

Meta categorized such posts as “recommended tools,” insisting that public posts should serve this function.

A corporate representative stated, “The shared images do not violate our policy and are postings from schools published by parents. There are systems in place to prevent teenagers from recommending shared threads.”

The 37-year-old London Instagram user who received the post requested to remain anonymous.

Skip past newsletter promotions

He noted he had not liked or posted similar images prior to receiving photos of the schoolgirl.

“To me, this feels intentionally provocative, introducing trendy and popular content, ultimately exploiting the children and families involved and jeopardizing online safety.”

“We advocate for children’s rights online,” said Beeban Kidron, a crossbench peer and advocate.

“Meta prioritizes corporate growth over children’s rights to privacy, which is the only reason we can fathom for sending a photograph of a female student to a 37-year-old man.”

She urged the Regulator of Communications to consider implementing measures this summer to prevent unidentified adults from contacting children, stating that “companies should not have the right to feed sensitive content to children.”

Ofcom’s illegal harm initiatives aim to combat online grooming, emphasizing that “Your child’s profile, location, and connections should not be visible to others.”

Meta’s system suggests that if a thread profile is public, posts from an adult profile could be recommended on Facebook or Instagram, allowing others to “discover, follow, and interact with you.” Users can turn this off or switch a thread profile to private.

Early Findings Indicate Elevated Risk of Colon Cancer in Long-Distance Runners

Researchers may have identified a potential connection between extreme endurance running and colorectal cancer, as nearly half of marathon and ultra-marathon participants have undergone screening.

Initial research assembled 100 long-distance runners aged 35-50 for colonoscopy, though these findings have not yet been peer-reviewed.

Close to 50% were found to have polyps (growths), with 15% diagnosed with advanced adenomas—growths that are likely to progress to cancer.

In contrast, recent studies indicate that only about 4.5 to 6 percent of adults in their late 40s from the general population have these advanced adenomas. However, it’s important to note that these studies included significantly larger sample sizes.

“I was quite concerned when I observed a group of ultra-marathon runners in their 30s diagnosed with stage 4, very advanced colorectal cancer,” said Dr. Timothy Cannon, who led the study at the Inova Schar Cancer Institute in Virginia. BBC Science Focus.

“They reported experiencing bleeding and convulsions post-race. At least one or two mentioned that they were told this was normal following their runs.”

Such symptoms can result from ischemic colitis, where blood flow is diverted from the colon to supply oxygen to the legs and other muscles during intense activity. This can lead to swelling and bleeding but typically resolves spontaneously.

Dr. Cannon speculated whether repeated cycles of damage and healing could create conditions conducive to cancer development.

Blood flow to the legs deprives the intestines of oxygen.

“There is currently no evidence that ischemic colitis directly causes cancer,” he stated. “However, it’s not difficult to imagine the potential outcomes. When numerous cells die and regenerate chaotically, there are ample chances for DNA replication errors.”

Alternative explanations exist as well. Endurance athletes are known to possess distinct gut microbiota compared to non-runners, and they often consume considerable amounts of ultra-processed foods, such as bottled energy drinks.

Dr. Cannon’s team is preparing to compare the gut bacteria of runners with and without adenomas to that of non-runners.

The findings were presented at the American Society of Clinical Oncology’s annual meeting, yet researchers cautioned that these are merely preliminary results, necessitating further investigation. They also highlighted that the screening study lacked a control group of non-runners.

“This leans more toward hypothesis than definitive answers,” Cannon remarked.

“I definitely don’t want people to walk away thinking exercise is harmful because it is beneficial overall. The inquiry is whether high levels of exercise could elevate the risk of colon cancer—and I believe they might.”

British AI Startup Outperforms Humans in Global Forecasting Competition

The artificial intelligence system has outperformed numerous prediction enthusiasts, including a number of experts. A competition focused on event predictions spanned events from the fallout between Donald Trump and Elon Musk to Kemi Badenok being dismissed as a potential Conservative leader.

The UK-based AI startup, established by former Google DeepMind researchers, ranks among the top 10 in international forecasting competitions, with participants tasked with predicting the probabilities of 60 events occurring over the summer.

Manticai secured 8th place in the Metaculus Cup, operated by a forecasting firm based in San Francisco aiming to predict the futures of investment funds and corporations.

While AI performance still lags behind the top human predictors, some contend that it could surpass human capabilities sooner than anticipated.

“It feels odd to be outperformed by a few bots at this stage,” remarked Ben Sindel, one of the professional predictors who ended up behind the AI during the competition, eventually finishing on Mantic’s team. “We’ve made significant progress compared to a year ago when the best bots were ranked around 300.”

The Metaculus Cup included questions like which party would win the most seats in the Samoan general election, and how many acres of the US would be affected by fires from January to August. Contestants were graded based on their predictions as of September 1st.

“What Munch achieved is remarkable,” stated Degar Turan, CEO of Metaculus.

Turan estimated that AI would perform at par or even surpass top human predictors by 2029, but also acknowledged that “human predictors currently outshine AI predictors.”

In complex predictions reliant on interrelated events, AI systems tend to struggle with logical validation checks when interpreting knowledge into final forecasts.

Mantic effectively dissects prediction challenges into distinct tasks and assigns them to various machine learning models such as OpenAI, Google, and DeepSeek based on their capabilities.

Co-founder Toby Shevlane indicated that their achievements mark a significant milestone for the AI community, utilizing large language models for predictive analytics.

“Some argue that LLMs merely replicate training data, but we can’t predict such futures,” he noted. “We require genuine inference. We can assert that our system’s forecasts are more original than those of most human contenders, as individuals often compile average community predictions. AI systems frequently differ from these averages.”

Mantic’s systems deploy a range of AI agents to evaluate current events, conduct historical analyses, simulate scenarios, and make future predictions. The strength of AI prediction lies in its capacity for hard work and endurance, vital for effective forecasting.

AI can simultaneously tackle numerous complex challenges, revisiting each daily to adapt based on evolving information. Human predictors also leverage intuition, but Sindel suggests this may emerge in AI as well.

“Intuition is crucial, but I don’t think it’s inherently human,” he commented.

Top-tier human super forecasters assert their superiority. Philip Tetlock, co-author of the bestseller SuperForecasting, recently published research indicating that, on average, experts continue to outperform the best bots.

Turan reiterated that AI systems face challenges in complex predictions involving interdependent events, struggling to identify logical inconsistencies in output during validation checks.

“We’ve witnessed substantial effort and investment,” remarked Warren Hatch, CEO of Good Judgement, a forecasting firm co-founded by Tetlock. “We anticipate AI excelling in specific question categories, such as monthly inflation.

Or, as Lubos Saloky, the human forecaster who placed third in the Metaculus Cup, expressed, “I’m not retiring. If you can’t beat them, I’ll collaborate with them.”

Revolutionary Quantum Funds Stored on Ultra-Cold ‘Debit Card’

Quantum Debit Card Ensures Financial Security

GlobalImages101/alamy

New quantum debit cards, which can hold unforgeable quantum funds, are constructed using extremely cooled atoms and light particles.

While standard banks often rely on the skill of counterfeiters to detect fake banknotes, quantum banks utilize the no-cloning theorem from physics, rendering counterfeiting impossible. This principle, which states that creating identical copies of quantum information is not feasible, led physicist Stephen Wiessner to propose a protocol in 1983 for generating secure currencies. Julian Laurat and his team at the Kastler Brossel Laboratory in France are actively implementing this groundbreaking concept in advanced experiments.

According to this protocol, banks create banknotes composed of quantum particles, possessing unique properties and existing in specific quantum states, thus ensuring protection against forgery through the no-cloning theorem. Laurat remarks that the protocol showcases an impressive feat of quantum cryptography, though it has not yet been put into practice for actual quantum fund storage.

The research team has made storage feasible by combining memory devices with hard drives. In their experiments, users interact with quantum systems that act as banks by exchanging photons. Each photon can be stored similarly to loading money onto a debit card.

The memory devices used by the team consist of hundreds of millions of cesium atoms, which researchers cool down to nearly absolute zero by bombarding them with lasers. At such extreme temperatures, light can precisely manipulate the quantum state of atoms, but Laurat notes that years were spent identifying the optimal cooling needed for atomic memory to serve as a quantum debit card. Through extensive testing, he and his colleagues demonstrated that users can retrieve photons from atoms without corrupting their states, as long as the process is not tampered with.

Christophe Simon from the University of Calgary emphasizes that the new experiment marks progress toward fully realizing quantum funding. However, the current quantum memory storage time of around six million seconds remains insufficient for practical application. “Another future step is to enhance portability. The long-term goal is to develop quantum memory that can be easily carried, particularly for Quantum Money applications. But we are not there yet,” he states.

The team is focused on extending storage durations, asserting that the protocol can be employed within quantum networks already being established in metropolitan areas across the globe. Additionally, cutting-edge quantum memory not only facilitates ultra-secure long-distance quantum communication but is also instrumental in connecting various quantum computers to more powerful systems.

Webb Discovers Intricate Structures in Saturn’s Upper Atmosphere

Astronomers utilizing the NASA/ESA James Webb Space Telescope have identified a series of dark, bead-like star formations within Saturn’s ionosphere and stratosphere.

Detection of near-infrared emissions in Saturn’s ionosphere (left) reveals dark bead-like features embedded in bright auroras. In the stratosphere (right), below 500 km, an asymmetric star pattern extends toward the equator. Image credit: NASA/ESA/CSA/WEBB/STALLARD et al.

“This was the first opportunity for me to make such detailed near-infrared observations of Saturn’s aurora and upper atmosphere,” said the researcher.

“We anticipated seeing emissions across various levels.”

“Instead, we observed intricate patterns of beads and stars, which might be interconnected despite their considerable height separation and could relate to the iconic hexagon within Saturn’s clouds.”

“These features were entirely unforeseen and remain unexplained.”

The research team concentrated on detecting infrared emissions from charged molecular hydrogen, which plays a significant role in Saturn’s atmospheric dynamics, offering valuable insights into the chemical and physical processes at work.

Using Webb’s near-infrared spectrograph, scientists observed H3+ ions at an altitude of 600 km, 1,100 km above Saturn’s nominal surface, alongside lower stratospheric methane molecules.

Within the ionosphere’s electrically charged plasma, a series of dark bead-like features intermingled within bright aurora halos were detected.

These structures maintained stability for several hours but seemed to drift slowly over time.

In the stratosphere of Saturn, researchers identified asymmetric star-shaped features, dropping approximately 500 km.

This remarkable formation extended from Saturn’s North Pole down toward the equator.

Only four of the star’s six arms were visible, with two mysteriously absent, resulting in a biased pattern.

“Studying Saturn’s atmosphere has always posed challenges due to the faint emissions from that region,” remarked Professor Stallard.

“Webb’s remarkable sensitivity transforms our capacity to observe these atmospheric layers, unveiling a wholly different structural configuration than previously noted.”

The authors meticulously mapped the precise locations of features, overlaying data for the same Saturn area, discovering that the arms of the star seem to emanate from a point just above the hexagonal structure at the Stormcloud level.

This implies that the mechanisms driving the pattern could influence structures penetrating through Saturn’s atmosphere.

“We believe the dark beads arise from the intricate interactions between Saturn’s magnetosphere and its dynamic atmosphere, potentially providing new insights into the energy exchanges that fuel Saturn’s auroras,” stated Professor Stallard.

“The asymmetric star formations suggest previously unknown atmospheric processes functioning within Saturn’s stratosphere and are likely connected to the hexagonal storm pattern observed deeper in Saturn’s atmosphere.”

“Interestingly, the dark beads in the ionosphere seem to align with the arms of the strongest stars in the stratosphere, though it’s unclear whether this connection is genuine or merely coincidental.”

Both phenomena may have significant implications for our comprehension of atmospheric dynamics within the gas giant, although further investigation is needed to elucidate their underlying causes.

The team aspires for additional time to conduct follow-up observations of Saturn using Webb to explore further features.

As planets align approximately every 15 years, the structure can undergo dramatic changes as Saturn’s orientation shifts toward the Sun, moving the Northern Hemisphere into autumn.

“The necessity for follow-up Webb observations during this pivotal phase of Saturn’s seasonal transition is evident, as neither atmospheric layer can be examined using ground-based telescopes.” Paper published in the journal Geophysical Research Book.

The findings were also presented as a result this month at the EPSC-DPS2025 Joint Meeting in Helsinki, Finland.

How Fat Storage Locations Impact Brain Function

Our brain activity and health is influenced by various bodily events

Cavallini James/BSIP/Getty Images

The impact of body fat on our movements, emotions, and even the likelihood of developing Alzheimer’s disease varies based on its location within the body.

While many studies emphasize abdominal fat due to its correlation with cognitive decline and heart disease, few have explored fat distribution in other regions, usually with limited participant numbers.

To broaden understanding, Qiu from the Hong Kong Polytechnic University and her team investigated the effects of fat in the arms, legs, torso, and around internal organs on brain health.

The research team analyzed body composition scans and Brain Imaging data of over 18,000 adults with an average age of 62 involved in the UK Biobank Project. After taking age and other factors into account, they associated excess fat in different body regions with specific brain changes.

For instance, higher fat levels in the arms and torso correlated with thinning in the sensorimotor cortex, which is involved in movement. Increased arm fat was also linked to reduced hippocampal volume, a crucial area for memory that is traditionally affected in Alzheimer’s disease, potentially explaining why arm fat is associated with a higher risk of neurodegenerative disorders.

The researchers found that excess leg fat correlated with diminished connectivity in the brain’s limbic network, which is responsible for emotion and reward processing. This may be due to the fact that fat in the lower body releases leptin, a hormone that regulates hunger, with higher leptin levels connected to reduced limbic connectivity.

Conversely, visceral fat (around internal organs) was the type most strongly linked to functional changes in the brain, uniquely associated with white matter degradation—a characteristic of Alzheimer’s disease—rather than its preservation.

This may arise from the fact that visceral fat produces more inflammatory substances compared to fat located elsewhere in the body, according to Sonia Anand from McMaster University in Canada, which can contribute to brain inflammation.

It remains unclear why arm fat appeared to have both protective and detrimental effects on the brain. “Observing such divergent impacts was intriguing,” noted Mikal Schneider Biary from Rutgers University, New Jersey. This complexity underscores the intricate relationship between body fat and brain health, she added.

The research only established correlations between body fat and brain function, so “we can’t infer any causal connections,” Biary cautions. Some brain changes may indeed influence the distribution of body fat. Moreover, the findings might not apply to the broader population, as there was a notable lack of diversity among participants.

Nevertheless, the study emphasizes that different types and locations of fat exert varying effects, according to Anand. This suggests that treatments focusing on reducing visceral fat could have a more significant impact on brain health than generalized weight loss approaches.

Rising Atmospheric Hydrogen: A Potential Climate Concern

Hydrogen can indirectly warm the atmosphere

axa/esa

Hydrogen levels in the atmosphere have surged by 60% since the pre-industrial era, underscoring the significant influence of fossil fuel use on the Earth’s atmospheric makeup. While hydrogen itself isn’t a greenhouse gas, it contributes to warming indirectly through its interactions with other substances.

The research findings stem from the first comprehensive long-term observations of atmospheric hydrogen, which are derived from ice core data collected in Greenland in 2024. “Ice core records are incredible,” notes Alex Archibald from Cambridge University.

Being a small and lightweight molecule, hydrogen tends to escape into the atmosphere easily, often leaking from the ice core before it is analyzed in the lab.

To tackle this issue, John Patterson from the University of California, Irvine, and his team examined the ice core samples right after extraction. “We took our equipment out onto the ice. As soon as we extracted the samples, we cleaned and sealed them in a melted chamber for analysis,” he explains.

This approach enabled the researchers to establish a long-term record of atmospheric hydrogen stretching back 1,100 years, marking a significant improvement over previous records that reached only 100 years, largely based on observational data and snowfall analyses. “It’s quite an impressive feat logistically. We’re excited to share these findings,” remarks David Stevenson from the University of Edinburgh, UK.

The study discovered that hydrogen concentrations have risen from roughly 280 parts per billion in the early 19th century to around 530 parts per billion today. According to Patterson, this is not surprising given the rapid increase in fossil fuel usage since the pre-industrial period—when fossil fuels or biomass burn, hydrogen is released as a by-product.

Patterson and his team merged data from ice core records with modeling efforts to illustrate the fluctuations in hydrogen levels over the millennium. “Our data reveals changes in atmospheric composition, but the reasons behind these changes remain unclear,” says Patterson. “We aim to utilize biogeochemical models to investigate these variations.”

Ice cores can reveal historical hydrogen levels in the atmosphere

John Patterson

For instance, evidence from ice cores indicates that atmospheric hydrogen levels dipped by 16% during the so-called Little Ice Age, a cold period from the 16th to the 19th century. The decrease in wildfire emissions during this time does not completely account for the notable drop in hydrogen concentrations, according to Patterson. “This suggests that natural hydrogen biogeochemistry is adapting to climate change in ways we still don’t fully comprehend. This unexpected finding could be significant for future scenarios, indicating that atmospheric hydrogen levels might be more sensitive to climate fluctuations than previously believed,” Patterson cautions.

In the atmosphere, hydrogen competes with methane and engages with hydroxyl radicals, which play a crucial role in eliminating methane from the atmosphere, a potent greenhouse gas. “As hydrogen levels rise, the amount of hydroxyl available to react with methane decreases,” explains Patterson, potentially enhancing methane’s warming effect. “Currently, hydrogen constitutes about half of the total in the atmosphere, contributing approximately 2% to the overall anthropogenic warming effect according to our best estimates.”

Gaining a deeper understanding of the hydrogen cycle is essential to assess whether the widespread adoption of hydrogen fuels, as a transition away from fossil fuels, might lead to unanticipated consequences. For instance, a sudden spike in atmospheric hydrogen could magnify the warming impact of methane. Methane emissions have consistently risen since 2007, influenced by fossil fuel production, agriculture, and warming that releases stored methane from wetlands and permafrost.

“Methane is a significant factor causing us to hesitate in endorsing a hydrogen economy, as it inevitably leads to hydrogen leaks into the atmosphere,” emphasizes Archibald. “If hydrogen escapes into the atmosphere, it worsens the methane issue.”

It might spark discussion over the cautious use of hydrogen, especially if renewable energy cannot sufficiently replace fossil fuels, according to Archibald. Nonetheless, Patterson and other experts highlight that the warming effects from increased hydrogen use are expected to be minimal compared to the considerable warming impact of fossil fuels. “We don’t want to discourage people from pursuing hydrogen energy, as it’s a much cleaner option than its fossil fuel counterparts,” emphasizes Patterson.

A single blood test can unveil the biological ages of 11 distinct organs and systems in the body, potentially indicating disease risks in those areas.

“Our objective is to enhance care using one test that reflects not just the overall biological age, but identifies which system is primarily influencing it,” explains Raghav Sehgal from Yale University. “This way, individuals can receive tailored lifestyle or treatment recommendations based on their profiles.”

To evaluate an individual’s lifespan and health risks, biological age serves as an indicator of the rate at which their body ages, contrasting this with chronological age, according to Morgan Levine at Altos Labs in California. Researchers have designed an epigenetic watch to assess DNA methylation, which involves the addition or removal of chemical tags that toggle genes on and off.

While it’s convenient, its accuracy is questioned by Levine. Different organs and systems age at varied rates, heavily influenced by genetics and medical history, she highlights.

“There is a common belief that within an individual, organs and systems can be distinct.” Vadim Gladyshev from Harvard University, who did not partake in the research, notes. “Some brains may exhibit older characteristics, while kidneys may age differently compared to other organs.”

Thus, Sehgal, Levine, and their colleagues embarked on creating methylation tests that target aging states in various body parts. Initially, they assessed physical measurements, including blood tests, medical histories, and grip strength from around 7,500 individuals involved in two major research programs, namely the Health and Retirement Study—a database of U.S. residents over 50 and some U.S. families contributing DNA for genomic research.

Researchers searched for clear connections between age-related conditions, encompassing immune, inflammatory, hematological, musculoskeletal, hormonal, and metabolic systems along with five key organs linked to the heart, lungs, kidneys, liver, and brain. They then correlated these findings with DNA methylation patterns, trained computer models to recognize those patterns, calculated the biological age of each system, and generated an overall biological age.

After training their models, the team tested it on blood samples from another 8,125 individuals whose data originated from four other studies. They discovered, for instance, that the model’s heart score could predict heart disease, brain scores were associated with cognitive decline, and musculoskeletal scores indicated whether individuals were likely to have arthritis-like conditions.

Comparing their findings with established epigenetic clocks, the researchers noted that organ-specific scores demonstrated strong accuracy, with many yielding excellent results. “It’s quite remarkable that a single factor measured through a blood test can effectively estimate aging across multiple systems,” remarks Levine.

Daniel Belsky from Columbia University in New York describes the epigenetic clock as representing “significant” advancements in aging research. “This marks the initial foray into developing interpretable measures of biological aging that allow for simultaneous analysis of multiple systems, guiding back to specific tissues or organs,” he explains. “It provides a pathway for reverse-engineering from aggregate measurements to pinpoint where health issues may emerge.”

Nonetheless, he cautions that this method might deviate from the overarching objectives of the field. “The essence of genetic science and the potential of aging biology resides in perceiving humans as coherent systems where we seek to identify the weakest links to bolster and avert failures,” Belsky asserts. “Maintaining this integrated perspective is crucial.”

Crucially, Levine clarifies that this test is not intended for diagnostic purposes but for risk assessment. “All assessments, including those in our studies, aim to provide estimates and insights into the inner workings of our bodies,” she emphasizes. “Future research should yield stronger and more precise estimates of aging by integrating various approaches, capturing the complexity and diversity of the aging process.”

Gladyshev envisions that this research could lead to personalized disease prevention strategies. “This represents the core implication of this series of studies,” Belsky adds, while emphasizing the need for further investigation. “We’re not quite there yet.”

Unveiling the Reality of Borneo’s “Vampire Squirrel” and Its Enormous Tail

Ever find yourself gazing at adorable things until they start to seem a bit creepy? Think of garden gnomes, baby dolls, kids dressed as princesses, and all cats. Well, there’s one more addition to this peculiar list.

The tufted ground squirrel (Rheithrosciurus macrotis) may appear cute with its bright eyes and bushy tail, but the Dayak hunters of Borneo view it as a cold-blooded killer.

This ruthless rodent, nicknamed “Vampire Alice,” is infamous for allegedly flipping deer onto their backs, using its razor-sharp teeth to sever their jugular veins, causing the animals to bleed out.

Those who discovered the remains of a deer in the woods suspect that the squirrel returns to the scene to feast on the deer’s heart, liver, and stomach.

In villages bordering the forest, tufted ground squirrels are also known to prey on domestic chickens and consume their hearts and livers.

The squirrel gained notoriety in 2014 thanks to a paper written by 15-year-old Emily Meyard, titled Academic Paper, which revealed folk tales about animals with a bloodthirsty reputation.

The paper was published in Taprobanica: Journal of Biodiversity in Asia and has since made these once-overlooked creatures go viral. Articles have been written, videos shared, perhaps making Beatrix Potter reconsider her legacy.

In 2015, footage of one caught on camera went viral for the first time, however, it did not catch any herbivores in the act.

Instead, they were seen foraging in Gunungparun National Park in West Kalimantan, where action from the killer critter remained elusive, but new revelations emerged.

In 2020, researchers discovered that the unusual teeth of these squirrels—long incisors with intricate ridges—are adapted for cracking open tough nuts.

Tufted ground squirrels are highly specialized seed predators, with a strong preference for canarium tree nuts.

It turns out the perception of tufted ground squirrels as fearsome creatures is a misconception. They truly have bright eyes and fluffy tails.

In fact, their bushy tails are among the largest proportionally of any mammal, being 30% larger than their bodies.

The reason for this unusual trait remains uncertain. Since they spend most of their time on the forest floor seeking food, it’s not for warmth, as it rarely gets cold in Borneo.

This could be related to attracting mates, deterring predators, or perhaps serving a mysterious form of camouflage. Their tail, which features a charcoal hue with frosty accents, helps them blend into the forest floor.

Regardless, I’ve stopped disparaging tufted ground squirrels and have learned to appreciate them as genuinely fascinating creatures.

Quantum Computers: Finally Attaining Unchallenged Dominance

SEI 232816755

Quantinuum’s Quantum Computer

Quantinuum

What unique capabilities do quantum computers possess that traditional computers cannot replicate? This question is central to a swiftly evolving industry, and recent findings aim to provide clarity on this topic.

Unlike classical bits, quantum computers utilize qubits that can occupy multiple states beyond just “0” or “1”, offering potential computational advantages. However, the debate on whether quantum computers can accomplish tasks beyond the reach of the most advanced traditional computers, including the notion of quantum supremacy, remains complex and contentious. This is primarily due to the stipulation that genuine demonstrations of quantum advantage must involve practical computational tasks, achievable with realistic quantum technology, while explicitly excluding any mathematical or algorithmic enhancements that may allow classical computers to eventually catch up.

William Crescher from The University of Texas at Austin and his colleagues are presently conducting experiments that satisfy both criteria. In contrast to earlier claims of quantum dominance, which were ultimately bridged by classical computing advancements, the researchers assert, “Our results are clear and enduring: no future classical algorithm development will close this gap.”

The team executed a complex mathematical experiment addressing communication challenges using 12 qubits created from laser-controlled ions by the Quantum Computing Company Quantinuum. The experiment’s objective was for two virtual participants, referred to as Alice and Bob, to devise the most efficient method for exchanging messages and performing calculations.

One section of the quantum computer, acting as Alice, prepares a specific quantum state and transmits it to Bob, another segment of the machine. Bob must discern its properties and determine how to measure Alice’s state to produce an output. By iterating this process, the duo can establish a means to forecast Bob’s output before Alice discloses her state.

The researchers conducted the procedure 10,000 times to refine the way Alice and Bob execute their tasks. With an analysis of these iterations and a rigorous mathematical examination of the protocol involved, it was found that classical algorithms with fewer than 62 bits could not compete with the performance of a 12-qubit quantum computer in this particular task. For a classical algorithm to achieve equivalent performance, it would require a performance threshold of about 330 bits, representing a nearly 30-fold difference in computational capability.

“This is an extraordinary scientific achievement that illustrates the extent of the ‘quantum advantage’ landscape, which may be broader than previously understood,” said Ashley Montanaro from the University of Bristol, UK. “Unlike most demonstrations of quantum superiority, the prospect of discovering a superior classical algorithm is virtually impossible.”

Ronald de Wolf from the Dutch Institute for Mathematics and Computer Science highlights that this experiment effectively leverages the recent rapid enhancements in existing quantum technologies while drawing upon theories of communication complexity that have been explored for years.

“The intricacies of communication are known to contribute to a verifiable and realistic distinction between quantum and classical systems. The difference is that advancements in hardware have made it feasible to implement the model for the first time,” he explains. “Moreover, they tackled a novel challenge in communication complexity, revealing a significant gap between classical and quantum capabilities even with just 12 qubits.”

These new findings differentiate themselves from earlier demonstrations of quantum superiority, but share a crucial element: their immediate practicality remains uncertain. Notable examples of quantum advantage that could produce substantial real-world benefits, such as Shor’s algorithm which could revolutionize encryption, still await confirmation regarding their applicability.

In the future, research teams might enhance their findings further by separating Alice and Bob into distinct computers. While this limits the chances of unmonitored interactions affecting outcomes of the quantum computer, the true utility of quantum dominance remains a critical issue, according to De Wolf.

“Progress beyond mere [quantum] dominance is essential for achieving [quantum] utility. Quantum computers currently outperform classical ones in specific areas of genuine interest, like some chemical computations and logistics optimization,” he suggests.

Amazon’s Deforestation Surges at Alarming Rates, Nearing a Critical Tipping Point

Scientists warn that the Amazon Rainforest has experienced a loss of the rainfall necessary to sustain it, pushing the world’s largest tropical ecosystem toward a potential tipping point.

A recent study published in Nature Communications indicates that deforestation is causing a significant decline in rainfall during the Amazon’s dry season, thereby increasing heat across the region.

Researchers suggest these changes could signify “early signs of biome destabilization,” implying that the forests are beginning to struggle to maintain their balance.

The study analyzed satellite and climate data from 1985 to 2020, encompassing an area of 2.6 million km² (1,000,000 square miles) in Brazil’s Amazon. This is nearly four times larger than Texas.

The data revealed that dry season rainfall has decreased by approximately 21mm (0.8 inches), with about three-quarters of this decline directly associated with deforestation.

During the same period, maximum daily temperatures increased by around 2°C (3.6°F), with 16.5% of this rise attributable to forest loss, while the remainder results from global climate change.

Plants play a crucial role in the Amazon’s rain cycle by extracting water from the soil and releasing it through a process known as transpiration.

When trees are removed, this cycle weakens, leading to fewer clouds and less rainfall. Consequently, the forest becomes hotter and drier, creating a harmful feedback loop.

If the Amazon reaches a tipping point, it may no longer be able to sustain itself, resulting in a rapid and irreversible collapse of the ecosystem and converting the region into a savanna.

This shift would significantly impact the entire water cycle in South America and release the carbon stored in the rainforests.

“These findings underscore the necessity of preserving and restoring Amazonian forest cover as a vital strategy for mitigating climate change and ensuring ecosystem stability,” the scientists conclude.

The Importance of Breakfast Timing for Longevity, According to Major Studies

As individuals age, having breakfast may be linked to a higher risk of early death, particularly for those in poor health. Recent research involving 3,000 adults indicates this connection.

After tracking participants for an average of 22 years, scientists observed that those who usually ate breakfast later in the morning had a slightly better survival rate in the following year compared to those who ate earlier.

Study participants typically consumed breakfast around 8:20 am, but those who waited until after 9 am were more prone to issues like depression, fatigue, or oral health problems.

“These findings provide new insight into the saying ‘breakfast is the most important meal of the day,’ especially for seniors,” stated the authors, including Dr. Hassan Dashti, a nutrition scientist at Massachusetts General Hospital.

“Our research implies that the timing of meals, particularly breakfast for older adults, can be a simple marker for assessing overall health.”

“Moreover, promoting a regular dietary schedule among older adults could be part of a larger strategy to enhance healthy aging and longevity.”

Participants were observed for over 20 years, during which they reported their health status, meal times, and occasionally provided blood samples.

Over time, researchers noticed that people were shifting their breakfast and dinner times later in the day, thereby shortening their overall eating window.

Since this study was observational, it does not definitively prove that delaying breakfast leads to health issues or early mortality; rather, it hints at a potential correlation.

Furthermore, researchers have determined that individuals genetically predisposed to “night owl” behavior are likely to rise and sleep later, consequently eating their meals later as well.

The authors emphasized the significance of their findings, especially considering the rising trend of intermittent fasting.

“The timing of subsequent meals, particularly delayed breakfast, is connected to health challenges and an increased risk of death among older adults,” Dashti concluded.
