New Study Examines Paleolithic Shift: Transition from Neanderthals to Anatomically Modern Humans

The transition from the Middle to Upper Paleolithic, occurring approximately 50,000 to 38,000 years ago, was a pivotal period characterized by the decline and extinction of Neanderthals alongside the emergence and expansion of anatomically modern humans, known as Homo sapiens. Paleoanthropologists at the University of Cologne have created a high-resolution model of population dynamics to reconstruct this significant transition on the Iberian Peninsula. Their ensemble simulations investigated Neanderthal survival, the arrival of modern humans, and the potential for interbreeding.

During this critical transition from the Middle Paleolithic to the Upper Paleolithic, Neanderthal populations experienced a steady decline across Europe, particularly in the Iberian Peninsula, leading to their eventual extinction.

Simultaneously, anatomically modern humans spread throughout Europe, marking a significant shift in human history.

This era was further defined by dramatic climate fluctuations, featuring alternating cold and warm periods. Rapid warming events occurred within centuries, contrasting with gradual cooling phases, known as the Dansgaard-Eschger phenomenon, which were punctuated by severe cooling caused by iceberg releases into the North Atlantic (Heinrich phenomenon).

The precise timing of Neanderthal extinction and the arrival of modern humans remains uncertain, leaving open the possibility of interactions between the two species.

Genetic analyses of archaeological bones compared to modern populations indicate admixture events in eastern Europe during the early phases of modern human migration.

Given the uncertainty of these dates, it remains possible that the two populations on the Iberian Peninsula may have intermixed at a later time, though this has yet to be substantiated.

In this innovative study, Professor Yaping Hsiao and his colleagues from the University of Cologne utilized numerical models to exploratory simulate potential encounters between Neanderthals and modern humans on the Iberian Peninsula.

These models considered ongoing climate changes while simulating the populations of both groups, along with their interactions and connectivity.

“By running the model multiple times with varying parameters, we can assess the plausibility of different scenarios, such as the early extinction of Neanderthals, small at-risk populations, or prolonged survival leading to admixture,” explained Professor Hsiao.

“However, for the majority of the simulations, the two groups did not converge.”

Across all scenarios, the populations exhibited high sensitivity to climate change.

Mixing between the two species was plausible if both populations could maintain stability over an extended period.

At a low probability (1%), a small fraction of the total population—approximately 2-6%—could possess genes from both groups by the end of the simulation.

This admixture likely occurred in the northwestern region of the Iberian Peninsula, where modern humans may have arrived early enough to interact with still-surviving Neanderthal populations.

“By integrating climate, demography, and cultural factors, our dynamic model provides a comprehensive framework that enhances our interpretation of the archaeological and genomic records,” stated Professor Gerd Christian Weniger from the University of Cologne.

Falling Asleep: A Sudden Shift, Not a Gradual Process.

We never just drift off; we abruptly enter slumber.

Dead Mitiei/Shutterstock

The brain doesn’t transition into sleep gradually. Instead, we hit a critical moment where we swiftly shift from being awake to asleep within just minutes. This finding could enhance the understanding and treatment of sleep-related issues like insomnia.

“Sleep is crucial to our existence, yet the mechanisms behind how our brain falls asleep have remained elusive,” states Nil Grossman from Imperial College London. It’s commonly thought that this change occurs gradually, with the brain smoothly moving from wakefulness to sleep; however, evidence for this phenomenon is sparse.

Grossman and his team have created a novel method to investigate how the brain functions during sleep by utilizing electroencephalography (EEG) data. This technique captures the brain’s electrical activity and provides insights into various sleep stages and wakefulness. The researchers analyzed 47 EEG signals using an abstract mathematical framework, treating each data point as if it were plotted on a map. This enabled them to visualize brain activity in its transition towards the designated sleep onset zone, correlating with the second phase of non-rapid eye movement (NREM) sleep.

“Now we can accurately monitor brain activity and determine how close individuals are to falling asleep each second, with a level of precision never achieved before,” explains Grossman.

The method was applied to EEG data acquired during the sleep onset phase of over 1,000 participants, measuring the proximity of brain activity to sleep onset. Generally, this proximity remained stable until about 10 minutes prior to sleep, markedly decreasing in the final moments. Researchers determined that this critical transition occurs roughly 4.5 minutes before sleep, marking the distinct switch from wakefulness to slumber, as noted by Li Junheng, also from Imperial College London. “[This is] the point of no return,” he states.

These findings indicate that the shift from wakefulness to sleep is “not a slow progression, but rather a sudden, dramatic transformation occurring in the last few minutes,” asserts Grossman. Thus, when we “fall asleep,” it closely reflects the underlying activity in our brains. “This showcases nearly the feeling of entering a different state,” he adds.

The research team subsequently gathered brainwave information from another group of 36 individuals, tracking each participant’s sleep patterns over a week. They utilized some of those nights to accurately predict when participants would fall asleep, within a minute of the actual moment.

“This indicates that while individuals differ significantly, each person seems to follow a unique sleep trajectory that recurs night after night,” remarks Laura Lewis from the Massachusetts Institute of Technology. However, she notes that it remains uncertain if these patterns alter when external conditions vary, like sleeping in a new environment.

While this framework does not explicitly identify the brain mechanisms responsible for the sleep transition, Lewis believes it could pave the way for future discoveries. “Identifying the precise moment of falling asleep has been quite challenging,” she states. “Once that is established, we can delve into the brain regions and circuits that facilitate sustained sleep.” Understanding the nuances of this transition could also aid in recognizing variations among individuals with insomnia, leading to innovative treatments.

OpenAI Expected to Navigate a $1 Trillion Market Shift

OpenAI is said to be gearing up for a stock market debut, potentially becoming the largest initial public offering (IPO) ever, with a valuation of $1 trillion (£760 billion) expected as soon as next year.

The creator of the popular AI chatbot ChatGPT is contemplating an IPO filing in the latter half of 2026, as reported by Reuters, based on information from sources close to the matter. The company aims to raise at least $60 billion.

The fluctuations in stock market shares offer OpenAI an additional avenue for funding, supporting CEO Sam Altman’s vision of investing trillions in the construction of data centers and other necessary infrastructure to accelerate chatbot development.

During a livestream on Tuesday, Altman reportedly stated: “Given our future funding needs, this is the most likely path for us.”

An OpenAI representative noted, “We cannot set a date as the IPO is not our priority. Our focus is on building a sustainable business and advancing our mission for the benefit of all through AGI.”

AGI, or artificial general intelligence, is defined by OpenAI as “a highly autonomous system that surpasses humans in performing the most economically valuable tasks.”

Founded in 2015 as a nonprofit, OpenAI aims to securely develop AGI for the benefit of humanity. Recently, the company underwent a major restructuring, transitioning its core operations to a for-profit model. Although still overseen by a nonprofit, this change facilitates capital raising and prepares the ground for an IPO.

As it stands, Microsoft holds approximately a 27% stake in the commercial entity, valuing OpenAI at $500 billion under the terms of their deal. Following the restructuring announcement, Microsoft’s valuation reached over $4 trillion for the first time.

Technology news outlet Information reported that OpenAI recorded revenues of $4.3 billion alongside an operating loss of $7.8 billion in the first half of this year.

Such enormous valuations do not ease concerns that the AI sector may be in a bubble. Bank of England officials have recently warned that tech stocks driven by the AI surge face heightened risk, noting market vulnerability if expectations about AI impact wane.

OpenAI’s Chief Financial Officer Sarah Friar has reportedly informed colleagues that the company is targeting a public offering in 2027, although some advisers speculate it could occur in the year prior, as reported by Reuters.

Your Happiness in Life May Not Follow a U-Shaped Curve—Here’s How It Can Shift

Our happiness levels vary throughout life

Ippei & Janine Photography/Getty Images

The widely accepted notion that happiness follows a U-shaped trajectory—with peaks in early and late life—may be misleading.

This idea gained traction from an original study by researchers David Blanchflower and Andrew Oswald, based on data from 500,000 individuals in 2008. Since then, it has permeated popular culture through mainstream literature.

However, researchers Fabian Kratz and Josef Brüderl at Ludwig Maximilian University in Munich argue that this belief may not hold true.

Kratz feels compelled to reevaluate the U-curve claim. The researchers analyzed self-reported happiness data from 70,922 adults who took part in the Socio-Economic Panel Survey in Germany from 1984 to 2017, modeling how happiness evolved over individuals’ lifetimes.

Contrary to the U-shaped model, they discovered that happiness typically declines during adulthood, only beginning to rise again in the late 50s.

Kratz believes that prior research may have drawn erroneous conclusions by oversimplifying the happiness trajectory and neglecting deaths due to suicide or illness. “It can seem that happiness increases after a certain age simply because those who are unhappy have already passed away,” Kratz explains.

“In the social sciences, there’s been considerable debate over conflicting findings—results often evaporate with new data collection,” says Julia Roller at the University of Leipzig. “Yet, another overlooked issue is that researchers may analyze data in ways that are systematically flawed. This can yield replicable findings, but still mislead.”

Others posit that these findings raise important questions. “This study provides an excellent opportunity to reconsider our understanding in this field,” remarks Philip Cohen at the University of Maryland, highlighting the need to explore why our happiness shifts throughout life and how we can ameliorate low points. Both Kratz and Brüderl express a desire to avoid speculation on the reasons behind these observed changes.

Oswald notes that the study presents “interesting results” worthy of consideration, but he emphasizes that factors such as marriage and income are beyond his control.

Furthermore, he points out that the study focuses on a single country, leaving it unclear whether these results are applicable elsewhere. Kratz suggests this may provide a useful foundation for future research. Notably, the findings could inform policy. “Previous scholars argued for the importance of proactive policies to help individuals navigate mid-life crises,” Kratz mentions. “While we do not dismiss this urgency, our results indicate that addressing declining well-being in older adults should be a priority.”

Breakthroughs in Body Clock Measurement Help Reduce Shift Work-Related Illnesses

EMS's ambulance team delivers medical aid to injured individuals and transports them on stretchers. Emergency medical personnel arrived at the traffic accident site.

Cemetery shifts earn their name for a reason. Individuals working night shifts face heightened health risks, including heart disease, type 2 diabetes, and depression. The World Health Organization has identified shift work as a potential carcinogen, given the increased likelihood of cancer.

While the rest of us are asleep, these night workers often go unnoticed, yet their efforts are vital to the medical and emergency services on which we rely. Though we depend on them for our very survival, the irony lies in how their work impacts their own health.

This situation could evolve with the advent of a test that accurately measures one’s internal biological clock in relation to external time (see “How innovative new tests can unleash the power of your body clock”). Such advancements in medicine promise to benefit a larger population.

Research indicates that many frequently used medications affect the body’s system, which operates on a 24-hour cycle, and are more effective when administered in harmony with this rhythm. Surgeries and vaccinations also yield better results at specific times of the day. Initial strategies often rely on standardized biological clocks, but for those whose circadian rhythms are misaligned, this approach may prove ineffective or even detrimental. This is where the new tests come into play.

Night workers may remain in the shadows, yet they are the backbone of essential services we all rely on.

Fortunately, these tests are expected to become more affordable and widely accessible. However, there is a concern that they could be misused by those anxiously trying to optimize their health, perhaps alongside other fitness metrics like step counts (refer to page 16).

The genuine potential lies in using these tests to gain insights into the biological processes of those in challenging situations, ensuring that in the future, the effects of nighttime work and improved strategies for managing shift patterns are addressed. One day, your biological clock may finally align with the external clock.

This could mitigate the health repercussions associated with night shifts and provide these employees with a chance to revitalize their lives. Employers must recognize this opportunity.

Microwave Tea? The Shift Among Generation Z from Kettles to Quick Brews

Item: A kettle.

Established: 132. First appeared in the catalog in 1893.

Outer appearance: It’s gradually becoming less common.

I’m not sure where this is going. Get with the times. Young people in the UK seem to have moved away from using kettles for tea.

Are they boiling water in a pot? Not ideal.

You can’t mean… I don’t want to say this, but they might be using a microwave now.

Can you hear that? King Arthur is weeping. Or perhaps they have a point. Maybe they are tired of brewing tea with disposable appliances clogged with old lime scale.

But it’s a tradition! That’s irrelevant. A survey of over 2,000 UK energy bill payers conducted by Uswitch revealed that 58% of individuals under 30 use microwaves for their tea. One in six admits to doing this daily.

Why’s that? Is it quicker? Not really. Boiling water for a mug takes 48 seconds in a kettle and almost 3 minutes in a microwave.

So, is the drink quality any better? No, it’s not. Dr. Tim Bond from the Tea Advisory Panel states that microwaves heat water unevenly, causing inconsistent tea extraction and a stewed flavor.

Why use the microwave then? There are two main reasons. Some students are forced to use microwaves due to university restrictions on kettles.

What’s the other reason? American influence.

What do you mean? Americans typically don’t use electric kettles, making them more likely to microwave water. Those influenced by American culture may start seeing this as the norm.

Oh. First, they picked Trump, and now this? It’s alright. This means owning an electric kettle has become a badge of defiance. The UK may have its flaws, but at least we know how to properly boil water.

Indeed! Our national chant is, “Tea before the milk!” Speaking of which…

What now? Years ago, scientists from the University of Leeds found that adding milk before the tea can actually enhance the taste.

This feels like a betrayal of all I hold dear. Don’t worry, it’s understandable; your struggle to change a light bulb and your discontent with their political system are perhaps more concerning.

All this makes microwave tea seem trivial. Absolutely.

Say: “I’ll brew a kettle…”

Don’t say: “… Sell it on eBay. Who drinks a refreshing cup of microwave tea?”

Police Expansion of Live Facial Recognition Cameras: A Shift Towards ‘General’ Surveillance

Authorities anticipate that live facial recognition cameras may soon be “prevalent” across England and Wales, as indicated by internal documents revealing nearly 5 million face scans conducted last year.

A joint investigation by the Guardian and Liberty investigates showcases the rapid integration of this technology into UK law enforcement practices.

The government is simplifying police access to a wide range of image repositories, including passports and immigration databases, for past facial recognition searches, alongside significant financial investments in new hardware.

Live facial recognition entails real-time identification of faces captured by surveillance cameras, compared against a police watch list.

Conversely, retrospective facial recognition software allows police to match archived images from databases with those recorded on CCTV or similar systems.

The implementation of this technology is believed to be widespread in urban areas and transportation hubs across England and Wales, as noted in funding documents produced by South Wales Police and shared by the Metropolitan Police under the Freedom of Information Act.

The inaugural fixed live facial recognition camera is set to be trialed this summer in Croydon, located south of London.

This expansion comes despite the absence of any mention of facial recognition in the relevant congressional legislation.

Critics contend that police are permitted to “self-regulate” this technology, while there have been instances where previous algorithms disproportionately misidentified individuals from Black communities.

Following a 2020 Court of Appeals ruling that deemed South Wales Police’s live facial recognition practices unlawful, the Police College issued guidance emphasizing that “thresholds must be carefully set to enhance the likelihood of accurate alerts while keeping false alert rates within acceptable limits.”

There remains no statutory framework directing the standards or technology applied in this context.

Earlier this month, Police Minister Diane Johnson informed Congress that “we must evaluate whether a tailored legislative framework is necessary to govern the deployment of live facial recognition technology for law enforcement,” but further details from the Home Office are still pending.

Facial recognition cameras have been tested in London and South Wales since 2016; however, the pace at which police have adopted this technology has surged over the past year.

A survey conducted by the Guardian and Liberty revealed:

  • Last year, police scanned nearly 4.7 million faces using live facial recognition cameras—over double the figures from 2023. Data indicates that a minimum of 256 live recognition vans were operational in 2024.

  • Mobile units comprising 10 live facial recognition vans can be dispatched anywhere in the UK within a matter of days to bolster national capabilities, with eight police forces having deployed this technology, while the Met has four such vans.

  • Authorities are exploring a fixed infrastructure to establish a “safety zone” by deploying a network of live facial recognition cameras throughout London’s West End. Met officials indicated that this remains a viable option.

  • The force has nearly doubled the number of retrospective facial recognition searches on the National Police Database (PND) from 138,720 in 2023 to 252,798. The PND contains administrative mug shots, including many held unlawfully for individuals not formally charged or convicted of any offenses.

  • Over the past two years, more than 1,000 facial recognition searches have utilized the UK passport database, with officers increasingly accessing 110 matches from the Home Office immigration database last year. Authorities concluded that using a passport database for facial recognition “presents no risk.”

  • The Home Office is collaborating with the police to develop a new national facial recognition system termed strategic facial matchers, which will enable searches across various databases, including custody images and immigration records.

Lindsey Chiswick, Met’s Intelligence Director General and the National Police Chiefs’ Council’s Facial Recognition lead, stated that five out of five London residents support the police’s utilization of advanced technologies like facial recognition cameras, based on the survey findings.

Recently, registered sex offender David Chenelle, a 73-year-old from Lewisham, was sentenced to two years after being caught alone with a 6-year-old girl through live facial recognition technology. He had previously served nine years for 21 offenses involving children.

In 2024, the Met arrested 587 individuals, with 424 of those arrests backed by live facial recognition technology, leading to formal charges.

Among those arrested, 58 registered sex offenders faced serious violations of their conditions, with 38 subsequently charged.

Chiswick noted: “Given the limited resources and time available, the demand is high, and we see criminals exploiting technology on an expansive scale.

“There’s a chance for law enforcement to evolve. Discussions about leveraging AI are abundant, but we must embrace the opportunities presented by technology and data.”

Chiswick emphasized that the Met’s approach is to “proceed cautiously and evaluate at each phase,” while noting that “there may be advantages to some form of framework or statutory guidance.”

The MET employs facial recognition cameras in contexts aimed at ensuring statistical significance regarding gender or ethnic bias in misidentification instances.

Chiswick remarked: “I refuse to utilize biased algorithms in London. Each instance carries weight. The government raises concerns: Is there no issue regarding artificial intelligence?

“When selecting an algorithm’s purchaser, determining the training data employed, and assessing the origin of the technology, testing it thoroughly is paramount; you are obliged to operate within a specific context.”

The Ministry of Home Affairs did not provide a comment upon request.

Wordplay in Transition: Exploring the Shift Between Novelists and Video Game Writers

I“I’ve spent over 15 years in the gaming industry, and one of the most frustrating aspects is explaining it at social gatherings. People frequently respond with, ‘Oh, I’m not really into gaming.’ I don’t particularly enjoy croissants, but that’s not the first thing I mention to a pastry chef I meet.”

One of the highlights of publishing my debut novel last year was the chance to sidestep that entirely and say, “Oh, I’m a writer.” I penned a novel. I’m currently working on another project. Now that you’ve wrapped up with work, we can continue our conversation. Nobody says, “Oh, I’m not really reading a book,” which is at least somewhat unlikely to be true.

It’s become evident that I’m not alone in transitioning between these two mediums. Why is that? For many, it boils down to finances. Writing novels is notoriously challenging as a source of income, and novelists have traditionally depicted careers across various fields. A 2022 report by the Author’s License and Collection Association (ALCS) revealed that professional authors earn a median of £7,000 annually from writing. Romance author Mallory Marlowe, whose debut love story became a bestseller last year, notes that her day job in video games supports her writing endeavors. “Fortunately, I receive a steady paycheck,” she states.

At the same time, game writers are facing their own struggles. GDC’s 2025 Game Industry Report indicates that one story designer and writer was let go last year. Naturally, some game writers are now exploring opportunities in other sectors.

Occasionally, writers create a direct connection between the two mediums, allowing them to influence one another. Written in both Scottish and English, Harry Josephine Giles’ “Game Like” serves as a precursor to her book “Deep Wheel Orcadia,” a poetry novel capably expressed in the 2022 Arthur C. Clarke Award-winning Orkney dialect. Meanwhile, John Ingold, co-founder of Narrative Game Studio Inkle (known for “80 Days!”), has released two novels set within the studio’s “Game Heaven Vault” universe. Ingold self-published these works. For him, writing them was a means to immerse himself more in the gaming world, but he remarked that “the novel’s plot proved challenging to construct. The main character consistently hesitates to abandon things.”

When I inquire about the primary differences in form from fellow novelist game writers, I’m often surprised by the diversity of responses. For some, it relates to the creative process. The act of writing a novel can serve as an escape from collaborative compromises, while games require immersive teamwork. Joe Dunthorne (author of “Submarine,” “The Tullterants”) has written novels, poetry, and most recently, a memoir titled “Radium’s Child.” Despite setbacks in the gaming industry, he commented, “After the solitude and madness of novel writing, I found relief going into the office each day. Collaborating with game designers was especially inspiring; I marveled at their ability to conceptualize complex, dizzying structures.”

Sharna Jackson creates children’s novels, including high-rise mysteries and nine-night quests. She has also contributed to the audio experiences of Die Gute Fabrik’s post-apocalyptic mystery games “Saltsea Chronicles” and “Yoto.” For her, the crucial difference lies in the volume of text available in games: “Many words remain unread or unheard, depending on the player’s choices within the experience.” Some of the most rewarding moments result in “rare occurrences and Easter eggs” that only a select few players may discover. Mallory Marlowe emphasizes the “strange independence” afforded to writers in gaming, yet acknowledges that novelists might take time to adapt to crafting narratives for players who approach story engagement with varying levels of commitment. “Some people just want to press a button and cause chaos,” she points out. “Others dive deep into the narrative.”

Ultimately, nearly everyone I converse with raises the distinct cultural status disparity between games and literature. Jim Munroe (author of “We Are Raccoons,” “Unmanned”) has been crafting games and books for over 25 years. He notes that books are culturally revered in a way that games are not. “Creators are engaged in gaming, despite its lower status,” he observes. Naomi Alderman, author of “Disobedience” and “Future,” echoes these sentiments. During a week when both her novel “The Power” and the game “zombies run!” (a co-creation involving six individuals) garnered awards, her book received attention on the front page of India’s Times, while “zombies run!” barely made a ripple within the specialized gaming press.

Conversations often circle back to the contrasting societal roles of gaming and literature, with varying responses to this reality. Munroe suggests that the gaming industry often attracts those with a penchant for independence. Marlowe appreciates the curiosity and confusion surrounding the notion of writing for games, cherishing the subsequent discussions. For Harry Josephine Giles, the unique space gaming occupies brings her joy; she underscores that games, being a newer form, have less rigid conventions. Early English novelists like Aphra Behn and Laurence Sterne disrupted norms, fundamentally altering the landscape, while today, only the most experimental novels enjoy similar flexibility. Games—carrying a lower cultural status—remain adaptable. As Dunthorne puts it, “Writing is often a lower priority in game design, and that’s alright. Games aren’t novels.”

Clearly, a new wave of young writers has emerged who grew up as native gamers, seamlessly transitioning between the two cultural forms without perceiving one as inherently superior to the other. Indeed, even in gaming, one might still encounter individuals at social events declaring, “Oh, I’m not really into them.” However, this might simply indicate the opportunity to create something extraordinary and unique while remaining unnoticed.

Judges reject initial attempt to halt commercial shift without masks, but schedule autumn trials for AI.

A United States judge denied a request for a preliminary injunction on Tuesday to halt the transition to an open commercial model, but agreed to hear the case this autumn.

Yvonne Gonzalez Rogers, a US District Judge in Oakland, California, stated that the tech billionaire did not meet the “high burden necessary for a temporary injunction” to stop the conversion to openness.

Nevertheless, Rogers expressed the importance of quickly resolving the lawsuit, considering “the potential for crisis and harm if conversion takes place unlawfully.”

Elon Musk and Openai, co-founded as a nonprofit in 2015 but left before it gained momentum, have been embroiled in a year-long legal dispute. CEOs of Tesla and X (formerly Twitter) have accused Openai of deviating from its original goal of developing artificial intelligence for the betterment of humanity, rather than corporate profits.

Openai and its CEO, Sam Altman, have denied these allegations. The lawsuit revolves around the shift to a for-profit model for chat developers, with Altman citing the need for more capital and competitiveness in the costly AI industry.

Openai welcomed the judge’s ruling, stating that Musk’s lawsuit, who launched rival startup Xai in 2023, was always about competition. Microsoft, the primary supporter of Openai, did not provide a comment.

Musk’s lawyer, Marc Toberoff, commended the judge for promising a swift trial on the core claims of the case. Toberoff emphasized the importance of ensuring Altman utilizes Musk’s charitable contributions for the benefit of the masses, not personal gain.

The ruling comes after Altman rejected a $97.4 million acquisition offer from a consortium led by Musk, claiming Openai is not for sale and accusing Musk of attempting to hinder its competitors.

OpenAI to Shift to For-Profit Company Structure, Announces Transition Plans

OpenAI has announced plans to reorganize its corporate structure in the coming year, noting that it will establish a public benefit corporation to oversee its expanding operations and alleviate constraints imposed by its current nonprofit parent company.

Speculations are circulating about OpenAI’s transition to a commercial entity. Details of the proposal have now been revealed for the first time.

According to the proposed framework, a for-profit public interest corporation will manage OpenAI’s business activities, while a nonprofit entity will oversee the organization’s philanthropic endeavors in fields like healthcare, education, and science.

This new structure grants greater authority to OpenAI’s commercial division. The company stated in a blog post that it aims to create a “more robust nonprofit entity supported by the accomplishments of a for-profit entity.” OpenAI also mentioned that this setup will enable them to “secure the necessary funding” comparable to other companies in the industry.

Initially established as a nonprofit research-focused organization in 2015, OpenAI is the creator of the popular ChatGPT chatbot and is considered one of the most valuable startups globally.

In pursuit of artificial general intelligence (AGI), a form of AI surpassing human intellect, OpenAI has been exploring structural modifications over the past year to attract additional investment. The success of the latest $6.6 billion funding round (valuing the company at $157 billion) hinged on restructuring and eliminating profit restrictions for investors.

“Investors are willing to back us, but at this scale of capital, we no longer require traditional funding with extensive structural constraints,” stated OpenAI in a blog post.

Microsoft holds the largest stake in OpenAI at 49%, a situation that could become intricate if OpenAI transitions into a commercial entity. Investment banks have been engaged to facilitate the process and determine Microsoft’s future ownership stake in the reorganized OpenAI. As reported by the Wall Street Journal.

OpenAI’s competitors in the generative AI sector, including Anthropic and Elon Musk’s xAI, have adopted a similar public benefit corporation model. OpenAI believes that adopting this structure can enhance its competitiveness in the market.

“The substantial investment being made by leading companies in AI development underscores the level of commitment needed for OpenAI to advance its mission,” mentioned OpenAI in a blog post. “We once again find ourselves in need of raising more funds than we had anticipated.”

Explanation of UK time shift and when clocks will go back to 2024


As the UK prepares for the clocks to change, two major shifts are on the horizon. Unfortunately, summer is coming to an end, but on the bright side, you’ll get an extra hour of sleep when the clocks go back in October.

But when exactly will this happen? And why do we turn the clocks back to March? Here’s everything you need to know.


undefined


When will the clocks change in October 2024?

The clocks will go back to 2am on Sunday, October 27, 2024, marking the end of Daylight Saving Time (DST) or British Summer Time (BST) and the switch to Greenwich Mean Time (GMT).

This adjustment means that the sun will set an hour earlier in London at 4:41pm on Sunday. However, the sunrise in London will also move back an hour from 7:45am to 6:45am, so you can expect a brighter morning.

Your smartphone will automatically update the time while you sleep, but get ready to reset your car, wall, and oven clocks the next day.

I hope this year I won’t have to keep pressing the minute button repeatedly to reset the time…

Why do the clocks change?

The practice of changing the clocks is more practical than scientific, allowing people to maximize daylight. Turning back the clocks in autumn means the sun sets earlier, giving us a head start on winter.

Where did daylight saving time originate?

The concept of daylight saving time can be traced back to George Hudson in New Zealand in 1895. He proposed adjusting the clocks to have more sunlight for activities. The idea was later supported by William Willett in the UK in 1907 to make better use of daylight hours.

Britain implemented daylight saving time in 1916 for energy conservation during World War I.

Why do some people want to end daylight saving time?

While many enjoy an extra hour in the fall, the spring clock change can disrupt sleep patterns and impact health. Studies have shown an increased risk of heart attack and decreased sleep quality during time transitions.

Experts suggest soaking up natural light and avoiding hitting the snooze button to adjust to the time change.

Are there benefits to abolishing daylight saving time?

Research has shown that serious traffic accidents decrease and crime rates lower with the adjustment of daylight saving time. Countries differ in their adoption of this practice.

Which countries do not use daylight saving time?

Most countries do not observe daylight saving time, including many in Africa. The EU is undecided on abolishing daylight saving time, while countries near the equator enjoy stable daylight hours.

Melting Ice Causing Earth’s Rotation to Slow and Axis to Shift, Research Finds

A recent study reveals that climate change is fundamentally reshaping the Earth, impacting its core. The melting of polar ice caps and glaciers due to global warming is causing a redistribution of water towards the equator, resulting in a shift in the Earth’s rotation and leading to increased daylight hours. This phenomenon is supported by new evidence suggesting that changes in the Earth’s ice could potentially affect its axis. These alterations create feedback loops within the Earth’s molten core, as highlighted in studies published in Nature Geoscience and the Proceedings of the National Academy of Sciences.

According to Benedict Soja, an assistant professor at ETH Zurich in Switzerland, human activities are significantly influencing the Earth’s rotation. Changes in the planet’s shape and mass distribution, influenced historically by forces like the moon’s gravitational pull and rebounding of crust after ice age glaciers disappeared, are now being accelerated by rapid ice melting caused by climate change. Soja warns that continued carbon emissions could make ice loss a more significant factor in Earth’s rotation than the moon.


In addition to external factors like gravity and ice loss, fluid movements in the Earth’s core also play a role in affecting the planet’s rotation. These movements can speed up or slow down the Earth’s rotation and are currently compensating for the slowdown caused by climate change. The new study suggests that climate change is leading to small variations in polar motion due to changes in mass distribution, estimated to be about one meter per decade.

These changes in rotation are expected to have implications for space missions, navigation, and timekeeping. Understanding how Earth’s rotation and axis are affected by climate change will be crucial for accurate space exploration and maintaining global time standards. The research emphasizes the interconnectedness of surface processes with the Earth’s core, shedding light on the complex relationship between human activities and the planet’s inner workings.

Paris Olympics to showcase city’s shift towards reducing air pollution by limiting car usage.

Paris, the host city for the 2024 Summer Olympics, has undergone a significant transformation in recent years. The city has made efforts to become greener by reducing its reliance on cars, setting an example for cities around the world.

Under the leadership of Mayor Anne Hidalgo, Paris has enacted several changes to promote sustainability. Over 100 roads have been closed to automobiles, parking fees have tripled, SUVs have been restricted, around 50,000 parking spaces have been removed, and over 1,300 kilometers of bike lanes have been built.

These efforts have resulted in a 40% reduction in air pollution, according to city officials. Hidalgo expressed that Paris would end its dependency on cars through disruptive changes.

Although European cities like Paris have been leading the way in reducing car use, similar reforms in the U.S. have been slow to materialize. The American infrastructure has historically been built around cars, making it challenging to transition to alternative modes of transportation.

The environmental reforms in Paris have garnered support from residents like Louise Kraustl, who believes that fewer cars and more walking and cycling make the city safer and less polluted. Inspired by the concept of the “15-minute city,” Paris aims to create pedestrian and bike-friendly neighborhoods where daily necessities are within easy reach.

While some cities in the U.S. have made progress in promoting biking and public transport, car dependency remains prevalent. Despite the challenges, experts emphasize the importance of reducing transportation emissions to combat climate change and improve air quality.

Paris’ efforts to prioritize sustainable urban planning serve as a model for other cities to follow. As cities worldwide grapple with the effects of climate change, the need for transportation reform becomes increasingly urgent.

The upcoming elections in Paris will be crucial in determining the city’s continued commitment to reducing car use and combating climate change.

Microsoft makes strategic shift, offers Xbox games to PlayStation and Nintendo | Games industry

Microsoft has announced that four previously exclusive Xbox games are being made available on PlayStation and Nintendo consoles. Additionally, the company plans to reveal details about the next version of its Xbox console by the end of 2024.

In a video podcast with other Xbox executives, Phil Spencer, Microsoft gaming CEO, did not reveal the names of the four games but mentioned that each is over a year old. Two of them are live service games and the other two are smaller titles. Spencer shared that his favorite games from the selection are the multiplayer pirate adventure Sea of Thieves and the musical action game Hi-Fi Rush. It has also been confirmed that the space epic Starfield from last year and the upcoming Indiana Jones game will remain exclusive to Xbox.

This move signifies a significant shift in strategy for Microsoft, focusing on increasing sales of first-party games rather than emphasizing hardware sales for Xbox. The company has faced tough competition from PlayStation ever since the original launch of Xbox in 2001.

To strengthen its gaming business, Microsoft has been actively acquiring various studios and gaming companies, such as Minecraft developer Mojang, Elder Scrolls and Fallout studio Bethesda, and Candy Crush publisher Activision Blizzard King. The acquisition process for Activision Blizzard involved extensive legal and regulatory procedures, but Microsoft is committed to making its popular games, including Call of Duty, available on other consoles.

Researchers Discover the Root Cause of a Historic, Lethal Climate Shift Millions of Years in the Past

Scientists have linked mass extinctions and climate change over the past 260 million years to massive volcanic eruptions and Earth’s astronomical cycles. The study highlights the role of CO2 emissions in climate change and reveals a complex relationship between Earth’s geology and position in space that is distinct from modern anthropogenic climate change.

New research reveals that Earth’s geological history is tied not only to the planet’s interior, but also to its astronomical movements.

The team of scientists concluded that it has occurred over the past 260 million years and that the mass extinction of life caused during these periods was primarily caused by large-scale volcanic eruptions and the resulting environmental crisis.

The analysis published in the magazine earth science reviews indicate that these eruptions released large amounts of carbon dioxide into the Earth’s atmosphere, resulting in extreme greenhouse climate warming and creating lethal or deadly conditions on Earth.

Astronomical cycles and Earth’s climate

Importantly, these phenomena occur every 26 to 33 million years and coincide with significant changes in the orbits of the solar system’s planets, which follow the same periodic pattern, the researchers added.

“Earth’s geological processes, long thought to be strictly determined by events inside the planet, may actually be controlled by the solar system and Earth’s astronomical cycles. milky way Galaxy,” says Professor Michael Lampino. new york university Department of Biology and senior author of the paper. “Importantly, these forces have converged many times in Earth’s past to predict dramatic changes in climate.”

The researchers, including Ken Caldeira of the Carnegie Institution for Science and geologist Sederia Rodriguez of Barnard College, say their conclusions are unrelated to climate change in the 20th and 21st centuries, and that scientists believe that human It warns that it shows that it is caused by activity. The last studied pulse of volcanic eruptions occurred about 16 million years ago.

But they added that the analysis nevertheless supports the well-established impact of carbon dioxide emissions on climate warming.

Volcanic eruptions and geological phenomena

Researchers have identified Continental Flood Basalt (CFB) eruptions, the largest volcanic eruptions on Earth with lava flows covering nearly 500,000 square miles, and other major geological events over the past 260 million years. focused. These include ocean anoxic events (periods during which the Earth’s oceans are depleted of oxygen, thereby producing toxic water) and the hyperthermal climate pulse, a sudden increase in global temperature and the resulting ocean and periods of mass extinction of non-marine life. .

They found that CFB eruptions frequently coincided with these other deadly geological phenomena, revealing the larger impact of volcanic activity. Its relevance to astronomy is evidenced by its regular, multimillion-year cycles of volcanic activity and extreme weather events, and its similarities with the known orbital periods of the Earth in our solar system and Milky Way galaxy.

The authors found that the correspondence between geological and astrophysical cycles was too close to be a mere coincidence. The big problem they were left with was how The astronomical movements of the planets disrupt the geological engines inside the Earth.

“This is an unexpected connection and predicts a convergence of both astronomy and geology. Events that occur on Earth occur within the context of our astronomical environment,” Rampino said. Observe.

Preparing Staff for the Shift to Clean Energy

clean innovation Technology and renewable energy are moving quickly, maybe a little too fast.

While there is no shortage of clean technology solutions available in today’s market (and we are developing them for the future), a new problem is emerging: a lack of talent to install and maintain the technology.

According to one study, the clean technology industry is expected to create 8 million jobs by the end of 2030. recent reports By the International Energy Agency. These numbers are clearly based on current policies, and the report’s authors expect these numbers to rise as more resources are directed to the clean energy transition. But just because more jobs are created doesn’t mean there are enough trained people to fill them.

Berlin-based Montamo wants to solve this problem. The startup hires and trains people to install and maintain sustainable heat pumps. We train people new to the industry, provide upskilling training to those with some experience, and have our employees install and maintain other companies’ equipment. As the company grows, it hopes to expand into other areas such as solar power generation.

Co-founder Alexander Boehm told TechCrunch+. Boehm said the company wants to be intentional about hiring and training migrant workers because it is difficult for immigrants to get good jobs in Germany, regardless of their skills or background. This is something Boehm witnessed firsthand when he worked as operations director for fast grocery delivery startup Gorillaz, and he doesn’t want their skills to go to waste.

Unveiling the Reality of Sleep Disorders: When a Night Shift Becomes a Nightmare

A new study investigated the relationship between shift work patterns, sociodemographic factors, and sleep disorders. They found that shift work, especially night shifts, significantly disrupted sleep, with about a third of all participants reporting at least one sleep disorder. The study also found that demographic factors such as gender, age, and education level influence sleep health.

A new study shows that working night shifts increases the incidence of sleep disorders, especially in young people with low levels of education.

Sleep is important not only for physical and mental health, but also for daytime and neurocognitive function. When people work in shifts (21% of workers in the European Union worked shifts in 2015), their circadian sleep-wake rhythms are often disrupted. Now, Dutch researchers have investigated the relationship between different shift work patterns, sociodemographic factors, and sleep disorders.

“Compared to working regular shifts during the day, working other shift types has been shown to have a higher incidence of sleep disturbances, especially those working rotational or regular night shifts,” GGZ Drenthe said Dr. Marike Lancel, a state mental health researcher.Institute and lead author of the study published in frontiers of psychiatry. “Notably, 51% of those working night shifts tested positive for at least one sleep disorder.”

ask about sleep

“There is a lot of evidence that shift work reduces sleep quality. However, there is little evidence of the impact that different types of shifts have on the prevalence of different sleep disorders and how this varies depending on demographic characteristics. “We know very little about whether they will,” Lancel continued.

To fill these gaps, researchers recruited more than 37,000 participants and provided demographic information indicating their shift work patterns (regular morning, evening, night, or switching between shifts).

They also completed a questionnaire screening on six common sleep disorder categories: insomnia, hypersomnia, parasomnias, sleep-related breathing disorders, sleep-related movement disorders, and circadian rhythm sleep-wake disorders.

Responses suggested that regular night shifts are the most debilitating condition when it comes to sleep. Half of night shift workers reported sleeping less than 6 hours in a 24-hour period, 51% reported one sleep disorder, and 26% reported two or more sleep disorders.

In the overall study population, approximately one-third tested positive for at least one sleep disorder and 12.6% tested positive for two or more sleep disorders.

Demographic factors and sleep health

Researchers also investigated whether demographic factors such as gender, age, and highest level of education influenced sleep health. We also considered whether participants lived alone, with a partner or children, or with others, such as friends or parents.

The results showed that although men slept less than women, sleep problems were more common in women. Age also affected sleep health. Although older participants tended to sleep less, most sleep disorders and their comorbidities were found to be more prevalent in the youngest participant group, those under 30 years of age.

Researchers found a correlation between education level and the likelihood of having disrupted sleep. “The effects of shift work on sleep are most pronounced among young people with low levels of education,” Lancel said. This group had shorter sleep duration and significantly higher prevalence of sleep disorders and their comorbidities.

Night shifts and sleep challenges

Researchers found that some people who work night shifts may have fewer sleep-related problems than others, but for the average night shift worker, this irregular work pattern can lead to less regular sleep-related problems. They said they would be more likely to struggle with healthy sleep. sleep. “People who work night shifts are unlikely to be completely immune to all the negative effects of night shifts, as they remain focused on their day jobs and out of sync with the environment in which they live,” Lancell said. explained.

The researchers also noted that their study had certain limitations. For example, people with sleep disorders may be more likely to participate in studies focused on sleep than people who sleep well. Nevertheless, the authors said their findings may provide important information for employers in occupations where shift work is common. It may also be used to educate strategies on how to best address and reduce the effects of night work and sleep days.

Climactic launches inaugural fund as partners shift focus to upcoming surge in climate technology M&A activity

A few years Earlier, when the pandemic was still in full swing, Raj Kapoor and Josh Felser started investing in climate change technology startups.they called their operation climax, and initially placed bets using their own money. Although we are both experienced founders, managers, and investors, this is our first time focusing on this specific sector and we started by testing the waters.

The company announced today that it has closed a $65 million founding fund and used it to support founders launching a climate technology software company.

Mr. Kapur and Mr. Felser both have long histories as investors, with Mr. Felser co-founding Freestyle Capital and Mr. Kapur spending seven years as a managing director at Mayfield Funds. They also founded and sold their own software startup.

It’s a little surprising that it took this long for the two to work together. Their resumes are strikingly similar. Felser said that in 1997 he founded Spinner (sold to AOL) and in 2004 he founded Crackle (sold to Sony). He also launched the #Climate nonprofit in 2014 and created a public-private coronavirus task force during the pandemic. Mr. Kapur previously served as chief strategy officer at Lyft, and before that he founded Snapfish (acquired by HP) and FitMob (acquired by ClassPass). He also launched a nonprofit climate social app in 2007.

Those experiences, combined with a growing concern about the state of the Earth’s climate, led the two to form Climactic.

“If we can get the top 50 supply chains to meet their net-zero goals, rather than just pay lip service, we’ll have the biggest impact,” Kapur told TechCrunch+. “To get there, we think the low-hanging fruit is software, because there are a lot of efficiencies to be gained.”
