The intriguing phenomenon of quantum superposition has enabled scientists to surpass the limitations imposed by fundamental quantum mechanics, equipping quantum objects with properties advantageous for long-term quantum computing.

For over a century, physicists have wrestled with the challenge of distinguishing between the minuscule quantum world and the larger macroscopic universe. In 1985, physicists Anthony Leggett and Anupam Garg introduced a mathematical assessment for determining the size threshold at which an object transcends its quantum characteristics. Quantum objects are recognized by remarkably strong correlations of their properties over time, akin to surprising connections between actions of yesterday and tomorrow.

Objects that achieve a sufficient score in this assessment are classified as quantum, with the scores traditionally held back by a value known as the temporal Zirelson limit (TTB). Theorists believed that even distinctly quantum objects could not surpass this threshold. However, Arijit Chatterjee and his colleagues from the Indian Institute of Science Education and Research in Pune have discovered a method to significantly exceed the TTB using one of the most basic quantum elements.

They centered their research on qubits, the essential building blocks of quantum computers and other quantum information systems. While qubits can be produced through various methods, the team utilized a carbon-based molecule incorporating three qubits. The first qubit was employed to control the behavior of the second “target” qubit over time, with the third qubit employed to extract properties from the target.

Though three-qubit configurations are generally believed to be constrained by the TTB, Chatterjee and his team discovered a method to push the target qubits beyond this limitation dramatically. In fact, their technique resulted in one of the most significant deviations from mathematical plausibility. The key was for the first qubit to govern the target qubit while it was in a state of quantum superposition, where it can effectively embody two states or actions that seem mutually exclusive. For instance, in their experiment, the first qubit directed the target qubit to rotate both clockwise and counterclockwise simultaneously.

Qubits are usually susceptible to decoherence over time, diminishing their capacity to store quantum information. However, after the target qubit surpassed the TTB, decoherence set in, yet the ability to encode information persisted five times longer due to its time-controlled behavior influenced by superposition.

According to Chatterjee, this resilience is advantageous in any context requiring precise qubit control, such as in computational applications. Team member HS Kartik from Poland’s University of Gdańsk mentions that procedures in quantum metrology, including accurate sensing of electromagnetic fields, could benefit significantly from this level of qubit control.

Rakura and their colleagues from China’s Sun Yat-sen University indicate that this research not only has clear potential for enhancing quantum computing practices but also fundamentally broadens our comprehension of how quantum objects behave over time. This is significant because immensely surpassing the TTB indicates that the properties of the qubit are highly interconnected at two divergent time points, a phenomenon absent in non-quantum entities.

The substantial breach of the TTB strongly demonstrates the extent of quantum characteristics present throughout the three-qubit configuration and exemplifies how researchers are advancing the frontiers of the quantum domain, says Karthik.

Extended Use of Melatonin Linked to Negative Health Outcomes

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

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

Levels of melatonin rise in darkness and fall during daylight.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

OpenAI Finalizes Transition to Commercial Enterprise Following Extended Legal Proceedings

OpenAI declared on Tuesday that it has officially transformed its core business into a for-profit entity, concluding a lengthy and challenging legal dispute.

Delaware Attorney General Kathy Jennings, an essential regulatory figure, announced her approval of a plan for the startup, initially established as a nonprofit in 2015, to transition into a public benefit corporation. This type of for-profit organization highlights a commitment to societal betterment.

The company also revealed that it has restructured its ownership and inked a new agreement with its long-time supporter, Microsoft. The arrangement will provide the tech giant with about a 27% stake in OpenAI’s new commercial venture, altering some specifics of their close partnership. According to the deal, OpenAI is valued at $500 billion, making Microsoft’s stake worth over $100 billion.


This restructuring allows the creators of ChatGPT to raise funds more easily and profit from AI technology while remaining under the nominal oversight of the original nonprofit.

Jennings stated in a release that she does not oppose the proposal, marking the end of over a year of discussions and announcements regarding the oversight of OpenAI’s governance and the influence commercial investors and their nonprofit board will exert over the organization’s technology. The attorney generals of Delaware, where OpenAI is incorporated, and California, where its headquarters are located, both indicated they were investigating the proposed alterations.

OpenAI confirmed it completed the reorganization “after almost a year of productive discussions” with authorities in both states.

“OpenAI has finalized a recapitalization and streamlined its corporate framework,” Brett Taylor, chairman of the OpenAI board, stated in a blog post on Tuesday.

Elon Musk, one of the co-founders of OpenAI and a former ally of Mr. Altman, had contested the transition through a lawsuit, which he later dropped, then refiled, and made an unexpected bid of nearly $100 billion to take control of the startup.

Skip past newsletter promotions

“Nonprofits will continue to oversee for-profit corporations and now have direct access to essential resources before AGI arrives,” Taylor noted.

AGI, or artificial general intelligence, is defined by OpenAI as “a highly autonomous system that surpasses humans at the most economically significant tasks.” OpenAI was founded as a nonprofit in 2015 with the goal of safely creating AGI for the betterment of humanity.

Previously, OpenAI stated that its own board would determine when AGI would be achieved, effectively ending its partnership with Microsoft. However, now “Once AGI is announced by OpenAI, this declaration will be confirmed by an independent panel of experts,” and Microsoft’s rights to OpenAI’s proprietary research methodologies will “persist until the panel of experts confirms the AGI or until 2030, whichever occurs first.” Microsoft also retains commercial rights to certain “post-AGI” products from OpenAI.

Microsoft also released a related statement on Tuesday regarding the revised partnership, but opted not to provide additional comments.

The nonprofit will be rebranded as the OpenAI Foundation, and Taylor mentioned it will allocate $25 billion in grants for health and disease treatment and to safeguard against AI-related cybersecurity threats. He did not specify the timeline for disbursing these funds.

Robert Wiseman, co-director of the nonprofit organization Public Citizen, remarked that this setup does not ensure autonomy for nonprofits, comparing them to corporate foundations that cater to the interests of for-profit entities.

Wiseman stated that while a nonprofit’s board may formally retain oversight, “control is illusory because there is no evidence that the nonprofit has enforced its values on the for-profit.”

Encounter Your Descendants and Future Self! Extended Travel to Reality Island at the Venice Film Festival

In Guests, the largest cinema at the Venice Film Festival, will converge for the premiere of Frankenstein. The stunning portrayal of Guillermo del Toro mirrors that of the creator who played God and crafted a monster. When a young scientist resurrects a body for his peers, some see it as a deceit, while others react with anger. “It’s hateful and grotesque,” shouts a hidden elder, and his concern is partially warranted. Every technological advancement unseals Pandora’s box. I’m uncertain about what will be craved or where this will lead me.

Behind the main festival venue lies Lazarete Vecchio, a small, forsaken island. Since 2017, it has hosted Venice Immersive, an innovative section dedicated to showcasing and promoting XR (Extended Reality) storytelling. Previously, it served as a storage facility, and before that, as a plague quarantine zone. This year’s judge, Eliza McNitt, recalls a time when construction halted as human bones were uncovered. “There’s something unforgettable about presenting this new form of film at the world’s oldest film festival,” she remarks. “We are delving into the medium of the future, while conversing with ghosts.”

This year, the island is home to 69 distinct monsters, ranging from expansive walk-through installations to intricate virtual realms accessible via headsets. Naturally, Frankenstein’s creations draw the attention of its makers, and McNitt acknowledges similar worries surrounding immersive art, which is often intertwined with runaway technology that poses a threat to all of us, frequently associated with AI.

“Immersive storytelling is a fundamentally different discussion than AI,” she states. “Yet, there’s a palpable anxiety regarding what AI signifies for the film industry. It largely stems from the false belief that a mere prompt can conjure something magical. The reality is that utilizing AI tools to cultivate something personal and unique is a collaborative effort involving large teams of dedicated artists. AI is not a substitute for humans,” she emphasizes, “because AI lacks taste.”




“Each experience requires a leap of faith”… Zan Brooks, left, experiencing the reflection of a small red dot. Photo: Venice immersion

McNitt has embraced AI tools early on and recently employed them in the autobiographical film Ancestra, set for release in 2025. She suspects that other filmmakers are not far behind. “I believe this experience here is merely the beginning of experimenting with these tools,” she says. “But next year, we will likely see deeper involvement in all aspects of these projects.”

The immersive storytelling segment at the Venice Film Festival aligns seamlessly with the film itself, encouraging attendees to view it as a natural progression or heir to traditional cinema. Various mainstream Hollywood directors have already explored this avenue. For instance, Asteroids, a high-stakes space thriller about disastrous mining expeditions, led by Dagriman, the Swingers director, reflects this trend. His production partner, Julina Tatlock, states that the interactive short films effectively brought Liman back to his independent roots, allowing him to conceive and create projects free from studio constraints. Asteroids is a labor of love, entwining elements of a larger narrative that could still be recognized as a feature of conventional cinema. “Doug is fascinated by space,” she adds.

The clouds possess a similar cinematic quality, floating above 2000 meters. This passionate arthouse drama depicts a grieving family pursuing the spirits of their deceased wives through the pages of uncompleted novels. Taiwanese director Singing Chen, adept in both traditional film and VR, believes each medium possesses unique strengths. “Immersive art was a pathway to film,” she remarks. “Even with the arrival of film, still images retain their potency and significance; they do not overshadow photographs. They affect us in ways distinct from moving images.”

Films in the Venice lineup are largely familiar. We often recognize the actors and directors, allowing for intuitive engagement with the storylines. In contrast, the artwork on the island can span a vast range—from immersive videos and installations to interactive adventures and virtual worlds. In the afternoon space, visitors can engage with the interactivity of an arcade game featuring Samantha Gorman and Danny Canisarro’s faces, along with a whistletop tour of Singapore’s cultural history. Every experience demands a leap of faith and hinges on a willingness to get lost. You might stumble, but you may also soar.




Visitors often meander through a dazzling…dark room. Photo: Venice immersion

Three projects stand out from this year’s Venice showcase. The Ancestors by Steye Hallema are lively ensemble interactives where visitors first form pairs, then expand into large families, viewing photos of their descendants on synchronized smartphones. This experience is unique in its pure focus on community, joyful yet slightly chaotic, embodying the essence of a good family. If Ancestors emphasizes relationship significance, here the form and content are beautifully synchronized.

The extraordinary blur by Craig Quintero and Phoebe Greenberg (likely the most sought-after ticket on the island) explores themes of cloning and identity, Genesis and extinction, requiring an impromptu immersive theater approach. It shifts perspectives, creating a bizarre, provocative, and enticing experience. As it concludes, users face a chilling VR representation of aging—a messenger from the future. The eerie, decrepit figure approaching me made me feel a year or two older than I actually am.

If there’s a real-world parallel to the Frankenstein scene, where an enraged scientist screams “hate” and “obscene,” it occurs when a middle-aged Italian finds himself in a dispute with the producer of sensory installations dubbed the Dark Room as he ferries to the island. He accuses the producer of being a Satanist. They assure him it’s not the case. “Maybe it’s not,” he responds. “But you did Satan’s bidding.” In truth, dark rooms are splendid and not at all demonic. Co-directed by Mads Damsbo, Laurits Flensted-Jensen, and Anne Sofie Steen Sverdrup, this vivid ritual tale immerses participants in a dynamic, intense journey through various corners of queer subculture, nightclubs, and backrooms, ultimately leading them across the sea. It’s captivating, disquieting, and profoundly moving. Visitors often navigate aimlessly, as I noted.

Initially, many stories at Venice oversimplified the experiences to comfort newcomers intimidated by technology. However, the medium is now gaining assurance. It has matured from its infancy to adolescence. This art form has evolved to become more robust, daring, and psychologically intricate. It’s no coincidence that many immersive experiences at Venice explore themes of ancestors and descendants, examining the connections between both. Moreover, numerous experiences unfold in mobile environments, fragile bridges, and open elevators. The medium reveals its current state—somewhere between stages of transit, perpetually evolving. It journeys between worlds, fervently seeking its future trajectory.

Is Ireland’s Extended Neutrality Putting It at Risk for Infrastructure Attacks? |Ireland

The internet’s foundation is crucial for various services, from entertainment platforms like TikTok to essential functions like emergency services, banking systems, and political and military communications.

However, the network of undersea cables around the coasts of Great Britain and Ireland has been targeted by military, terrorist, or criminal actors, leading to incidents where internet cables were cut, disrupting communication in the Baltics. As 75% of transatlantic cables pass through or are near Ireland, the strategic importance of these cables is significant for the UK and Europe.

Recent incidents, such as cable cuts between Finland and Estonia, have raised concerns about the security of Ireland’s exclusive economic zone (EEZ) that extends beyond its coast.

Ireland’s neutrality and limited defense capabilities have left the country vulnerable to potential threats. Calls have been made for a reassessment of Irish defense policies and the need to secure vital infrastructure.

There is growing recognition that Ireland’s neutrality may not shield it from modern threats, and steps must be taken to protect against potential attacks on critical infrastructure.

Remaining Accountable: Understanding the Extended Range of Plug-in Hybrids

Despite the growing number of electric and hybrid vehicles on the roads, some individuals remain apprehensive about range and access to charging points, particularly if they rely on their vehicles for work. These concerns persist.

Fleet managers and business owners, with myriad responsibilities, may find the transition away from gasoline daunting. Nevertheless, advancements in battery technology and substantial investments in charging infrastructure have made the switch to electric or hybrid more feasible and potentially cost-effective for businesses than ever before. So, what factors should you consider to extend your battery-powered driving range?

Have you thought about a plug-in hybrid?
It’s advisable to explore plug-in hybrid electric vehicles (PHEVs) first. These vehicles feature rechargeable batteries and gasoline engines, with only a few running on diesel. They can be charged at both domestic and public charging points and now offer impressive pure electric ranges.

On the other hand, hybrid electric vehicles (HEVs) rely on the car’s movement to generate electricity and use battery power to reduce gasoline consumption and emissions. They cannot be charged by plugging into a power outlet.

Modern plug-in hybrids like the Škoda Superb offer impressive range

The latest plug-in models showcase the significant technological advancements, with fast charging capabilities, remarkable range, and battery capacity. “For instance, the Škoda Superb Estate can travel up to 84 miles on pure electricity,” says Alan Barrowman, Skoda’s national contract employment and leasing manager. He also noted that this mileage qualifies for the 5% benefit-in-kind (BiK) tax for company car drivers.

Changes in charging
Charging networks are crucial for PHEV drivers looking to minimize their petrol (or diesel) usage. Fortunately, the number of public charging points is constantly increasing. In October 2023, approximately 50,000 points were installed at various service stations, with the installation rate continuing to rise. According to Zapmap, a data firm, there were 68,273 electric vehicle charging points across the UK by the end of August this year, representing a 41% year-on-year increase. Additionally, there are an estimated 700,000+ home and workplace charging points.

Charging points supply either alternating current (AC) or direct current (DC) power. Electric car batteries can only store DC power, so connecting to an AC charger involves converting the current, which can be time-consuming. Vehicles that support both AC and DC charging points, such as the all-new Škoda Superb, can charge even faster. The Skoda www.theguardian.com

Research reveals that Mycenaean armor was created for extended battles

A 3,500-year-old Mycenaean bronze suit of armour discovered in the Greek village of Dendra may have been used in combat and not just for ritual purposes as previously thought.

One of the oldest armors discovered in Europe is a 3,500-year-old suit of armor found near the village of Dendra, a few kilometers from ancient Mycenae in southern Greece.

Since its discovery in 1960 by a team of Greek and Swedish archaeologists, it has been unclear whether it was ceremonial clothing or gear suitable for combat.

This question has important implications for understanding warfare in Late Bronze Age Europe, yet there is no historical record of the use of this style of armour.

In a new study, Professor Andreas Floris from the University of Thessaly and his colleagues combined historical and experimental evidence to investigate the combat suitability of Dendra armour.

The researchers recruited 13 volunteers from the Greek Marine Corps, outfitted them with replica Dendra armour and Bronze Age weapons, and had them carry out 11 hours of simulated Bronze Age combat protocols.

This battle simulation was developed based on the historical records of Homer. Iliad Additionally, we add physiological and environmental evidence to approximate the typical diet, activities, and operations of a Mycenaean army.

Testing has shown that the replicated Dendra Armor does not restrict a warrior's combat capabilities, nor does it place undue strain on the wearer.

These results suggest that Dendra armour was battle-hardened and that the Mycenaeans' powerful influence on Mediterranean history was due in part to their armour technology.

To complement these results, the authors developed freely available software that allows for the simulation of combat conditions and allows testing the hypothetical effectiveness of the armor in more diverse scenarios.

“The armour worn by our volunteers had the same dimensions as the Bronze Age originals and weighed roughly the same,” Professor Floris said.

“We also monitored calorie intake based on the Homeric diet (about 4,443 calories), which Iliad“It linked calorie expenditure and the stress placed on the volunteers' bodies in typical Greek summer temperatures of 30-36°C.”

“As the 11-hour combat protocol began, we measured heart rate, oxygen consumption, core body temperature, fluid loss and muscle function.”

“We found that this armor allows complete flexibility of movement and does not place undue physiological stress on the body.”

“This means that, despite previous views that classified the armour as ceremonial clothing, it could have been worn for extended periods during battle by healthy individuals.”

“Sixty years have passed since the discovery of Dendra armour, and we now know that, although seemingly cumbersome, it was not only flexible enough to permit nearly all of a warrior's movements on foot, but also durable enough to protect the wearer from most blows.”

The unexpected explanation for why humans experience an unusually extended period of childhood

I was going to start this article differently. But that was before my 10-year-old daughter intervened. In fact, I had already started writing when she got up and tried to trick me. She offered to bet me her ten pounds that I could write red with a regular pencil. Unfortunately for this budding entrepreneur, I turned down the bet. She was so confident that she suspected he was up to something. But I let her reveal the trick. She took her lead pencil in her hand and she wrote, “In red color.” Then she laughed like a hyena and went out to fool her mother.

Our bright little sparks have opinions on everything from video games to sports to books. She’s learning basic algebra and coding, but her Taylor Swift expertise far exceeds mine. But even with all this knowledge, she still has many years to go before she reaches adulthood. If she lives out her average lifespan, she will spend a quarter of her year as a minor.

It is truly strange that humans have long childhoods. No other primate takes this long to reach adulthood. During the evolution of our species, childhood has become significantly longer, along with more obvious physical changes. Traditionally, paleoanthropologists have paid little attention to children, but that is now changing. A series of interesting discoveries over the past few years are building a complete picture of human childhood. When did this seemingly unproductive life stage expand, why was it so long, and what did prehistoric children do? This discovery does more than just shed light on a dark corner…
