The “godfather of AI” believes that AI LLMs are a dead end. Meta has turned him into a vase scientist

November 17, 2025 by usatoday24

Yann LeCun has been warning for years that Generative AI is stupid. The current models, he claimed a year ago, are no more intelligent than a domestic cat. This speech has become especially uncomfortable especially because LeCun, considered one of the godfathers of AI, was until now one of the most responsible for this segment in Meta. Now everything seems to point to an imminent departure that will see LeCun found his own startup. Why is it important. While AI companies strive to train AI models by collecting more data and spending billions of dollars on computing power, LeCun is clear that this strategy is a dead end. It is something we have been talking about for a long time and that other experts like Andrej Karpathy have also have warned: This scaling of resources previously allowed notable leaps in performance. Not now. He knows what he’s talking about. In 2003 LeCun joined New York University and later founded the institution’s Data Science Center. In 2013, Mark Zuckerberg recruited him to lead his new AI division at Facebook called FAIR (Fundamental AI Research). In 2018, LeCun, along with Geoffrey Hinton and Yoshua Bengio, won the Turing Awardthe highest honor in computer science, for his contribution to the study of neural networks. LLMs must give way to “world models”. LeCun has prophesied that within three to five years no one in their right mind will be using today’s LLMs. Instead of them, the architecture that will triumph will be that of the so-called “world models”which learn from the environment through visual information, similar to how a baby does, in contrast to LLMs, which are predictive models based on vast text databases. Internal tension. That vision of LeCun has ended up being a problem in Meta. Mark Zuckerberg does not seem to have the same opinion, and in recent months he has made it clear. with a bet multimillionaire in which ended up signing talent and creating its new superintelligence division that precisely reinforced the role of the LLM that LeCun sees as useless. An uncomfortable situation. These signings have caused the FAIR Group that LeCun led to lose prestige, resources and weight in the organization compared to that new AI research organization led by the new rising star, Alexandr Wang. Exit in sight. Last week the first rumors appeared that LeCun is planning his departure from Meta to create his own startup. Precisely this new company would explore the creation of those models of the world that this scientist and researcher wants to develop in depth. If he executed that step, it is very likely that the investment world would support that vision and offer him sufficient funds to work on it. It has happened with startups Ilya Sutskever and Mira Muratithat without having visible product They have achieved multi-million dollar financing rounds. LeCun seems to be right. The evolution of LLMs seems to confirm LeCun’s theory that they are not the valid way to achieve truly notable advances in the field of AI. What current models do is not so much solve problems as locate past instances of solved problems to use probability and apply answers. Don’t even think about pursuing LLMs.. In recent months, LeCun’s work in Meta has become more blurred and he has been seen participating in several conferences. In one of them gave a message clear to those aspiring to get into this field: “if you are a PhD student in AI, you should never work with LLMs.” Image | Goal In Xataka | The only advantage Apple could have in AI was its private cloud.

The world keeps asking for more F-35 fighters, but China has turned off the tap to build them

November 12, 2025 by usatoday24

He F-35 Lightning IIthe fighter more expensive and complex never built, is going through a critical point in its history. In September 2025, a report of the United States Government Accountability Office (GAO) revealed that all deliveries in 2024 arrived late, accumulating an average of 238 days late. Now, a leak has revealed that delays can multiply, and China plays a fundamental role. The problem of the largest military program. They remembered a few months ago on Insider that the 2024 delays had one main cause: the stagnation of the Technology Refresh 3 technology package (TR-3), an essential hardware and software update on which the block 4 modernizationalready with an extra cost of 6,000 million dollars and five years behind schedule. The paradox was that, despite maintenance failures, deficiencies in availability and costs that already exceed 2 trillion dollars Throughout its service life, the F-35 remains the cornerstone of American and allied air defense. More than 2,500 units remain in the Pentagon’s planning, while the current fleet is barely “operational” half of the time. More money. Lockheed Martin, its prime contractor, continues to receive incentives even for late deliveriesin a program that no longer only faces technical delays, but a much more structural threat: global dependence on its supply chain. A global network. The F-35 is, by definition, a multinational aircraft. Of the more than 1,200 devices manufactured to date, about 42% of its components are produced outside the United States, in an industrial network that involves more than twenty countries. The United Kingdom, the only Tier 1 partner, manufactures in Lancashire the rear fuselages of all the F-35s in the world, as well as their tails, ejection seats and part of the electronic warfare system code. Italy and the Netherlands assemble structures and optical systems, while Australia, Canada, Norway or Denmark provide fuselage sections, wings or specialized electronics. Germany, Japan and Israel also contribute critical parts: from fuel tanks to helmet-mounted visors. This ecosystem, which combines thousands of suppliers under a single oversight, has made the F-35 the largest industrial cooperation project of defense of the planet. The small print. But, despite the geographical dispersion, total control The United States preserves it: the Department of Defense and Lockheed Martin jealously guard it the source codemaintenance keys, stealth algorithms and the ALIS logistics system, without which no country can operate the aircraft independently. Each export includes clauses that maneuvers are prohibited joint with Russian or Chinese systems and allow Washington to supervise every flight, every review and every software update. You hunt like hotcakes. By 2025, Lockheed Martin has opted to reverse the narrative of delays with a figure that reflects both ambition and vulnerability: manufacturing 200 fighters in a single yearone for each working day. In its third quarter earnings call, CEO Jim Taiclet announced that 143 units had already been delivered, with an order book valued at 179 billion dollars, the largest in the company’s history. The boom responds to the global increase in defense spending, with European countries accelerating its rearmament and new buyers (such as Finland or Japan) incorporating the F-35 as the central axis of their fleets. The plane has become a tool deterrence and cohesion between allies, a symbol of interoperability under the umbrella of Washington. But industrial success hides a strategic fragility: the complex network of components of the F-35 depends, directly or indirectly, on materials that almost entirely come from Chinafrom rare earth magnets to elements for critical sensors, servomotors and actuators. Beijing’s silent weapon. Through a Wall Street Journal exclusive We have learned that, while Lockheed Martin celebrated its best year for deliveries, China moved its own parts with surgical precision. Beijing announced the creation of a system of “validated end users” (VEU) to regulate the export of magnets and rare earth metals: essential materials for both F-35 fighters and submarines, drones or electric vehicles. The plan, presented as a measure of trade opening after the tariff truce between Xi Jinping and Donald Trump, in reality aims to exclude any company from the flow of exports. linked to the military complex United States. In other words, the companies that supply the F-35 (from engine manufacturers to aerospace subcontractors) will be blocked, while supplies to civilian industries are prioritized. Strategic deterrence. With this system, Beijing can formally fulfill its promise of liberalize tradewhile suffocating the critical chains of the North American defense sector. The VEU architecture, inspired by the United States’ own export control mechanisms, turns industrial policy into a deterrent instrument strategic. The bottleneck. Chinese control over rare earths (70% of the extraction and more than 90% of the world’s processing) places Washington before a structural dilemma: Your most advanced hunting depends on a monopolized resource by its main geopolitical rival. Although the White House seeks to diversify sources through agreements with countries such as Kazakhstan, Greenland or Ukraine, replacing Chinese capacity will take years. In recent months, Chinese magnet exports to the United States fell 29%which has already begun to affect engine and guidance system manufacturers. If Beijing strictly implements its new system, it would not only slow down F-35 production, but could temporarily interrupt the logistics chain for maintaining fleets already deployed. In that scenario, the program that symbolizes Western technological supremacy would be conditioned by dependence on a strategic enemy. The paradox of a fighter. The F-35 was born as an emblem of interoperability and technological masterybut its evolution shows that military superiority is no longer measured only in radars or missiles, but also in access to mineralschips and advanced materials. As the world’s most expensive plane is assembled from parts manufactured on three continents and with magnets processed in China, its story becomes a metaphor for the 21st century: a war of interdependencies where each fighter that takes off carries within it a dose of global vulnerability. Thus, while Lockheed Martin tries to maintain its record pace of production and the Pentagon reinforces its leadership narrative, the real battlefield is being fought in the mines, laboratories … Read more

A tiny Spanish town with 13 houses can’t take it anymore. A murder has turned it into the capital of crime tourism

November 10, 2025 by usatoday24

High in the Catalan Pyrenees, among clouds, forests and cows grazing in the rain, Tor risesa village of just thirteen houses where three decades ago a crime occurred that forever marked its inhabitants. In 1995 appeared the body of Josep Montanéknown as Sansa, with an electric cable around his neck and the corpse dragged to his kitchen. It was the third murder in fifteen years in a place too small for so many deaths. Today it seems the decoration of the mythical “A crime has been written”. National myth. History recovered this weekend the new york times as an example of a type of tourism which has been added in parallel to that of sun and beach. What seemed like a rural reckoning became, over time, a a national story about greed, secrets and institutional abandonment. the mountain, shared since 1896 by the town’s families under an ancestral agreement, had become the object of dispute between those who dreamed of a lucrative ski resort and those who wanted to preserve their peasant life. The conflict, fueled by smuggling interests and disputes over ownership, culminated in the judicial grant of the mountain to Sansa and, five months later, in her death. Then came the cultural phenomenon. From tragedy to true crime. The Catalan journalist Carles Porta, then a young reporter, was the one who turned the Tor crime into a media obsession. It started with a television report In 1997, he continued with a book in 2005, a podcast very successful in 2018 and a documentary series in 2023 that transformed the small town into the epicenter of Spanish “true crime.” Porta, fascinated by Truman Capote’s In Cold Blood, found his own Holcomb in that Pyrenean valley and turned the story in an industry. Over the years, the public’s fascination with unsolved crimes attracted visitors from all over the country: curious people, mystery fans and hikers who wanted walk the stage of the murder, staying at Sansa’s old house or posing in the places where the police found evidence. Some even recreated the crime scene. with cables around the necka morbid parody that the neighbors watch with a mixture of bewilderment and resignation. Tor Municipality Crime tourism. The Times remembered that media notoriety brought money, but also disfigured life in Tor. In summer, the streets are filled of cars, the houses become scenery and the neighbors become involuntary characters in a story that never ends. In the Alins family hostel, at the foot of the mountain, phrases by Porta and bottles of liquor with quotes from his book hang, while the visitors ask relentlessly “who killed Sansa.” Merce Turallols, who was a girl when the body appeared, admits that fame has benefited the family business, but he confesses that the residents can no longer stand the circus: in the busiest months, you can’t even park and eccentric tourists tour the town disguised as victims. And more. “One arrived with a rope around his neck,” they remembered in the report. Porta himself, now producer of documentaries for Disney Regarding other cases, he recognizes that Tor’s has become his personal legacy, a phenomenon without end. The man assures have new clues (a possible hitman who lives in Miami) and the intention to close the case with a fiction series, but the people, who never saw justice or rest, feel that the journalist has exploded its tragedy to the limit. Town turned into a stage. Thus, going through Tor today is like going through a museum of rural crime: the local guide point out the places where the body was dragged, the house where a hippie committed suicide, the abandoned car of some smugglers, the meadows where neighbors charged tolls to those who crossed with goods from Andorra. Everything has become anecdote for visitors who seek excitement, while local people demand something as simple as mobile coverage or tranquility. Pilar Tomàs, who lives across the street from Sansa’s old house and was the one who found him dead, serves homemade food in her restaurant full of strangers. He appreciates the increase in clients, but would like a life without cameras nor curious. He joked in the media that if Porta has benefited so much from the case, he could donate at least enough for a telephone antenna. The rise of crime tourism. The call “dark tourism”sordid or thanatotourism has ceased to be a rarity and has consolidated itself as a global trend that turns tragedy into destiny. From the streets of Barcelona’s Raval, where the crimes of Enriqueta Martí either of the “Arropiero”even the towns devastated by the civil war like Belchitethe tourism industry has been able to capitalize on human fascination with death and evil, an interest as old as the shows of the Roman circus. According to the criminologist Vicente Garridothis attraction responds to the mixture of fear and curiosity in the face of the unknown, but today it takes the form of guided routes, theatrical visits and immersive experiences where the visitor seeks to understand (or feel) the echo of horror. New narratives to enhance it. Series and podcasts true crime have reinforced this phenomenon, generating a media aesthetic that romanticizes murder and transforms the victims and executioners into cultural characters. In Spain, theplaces like Torwith their story of unresolved deaths, symbolize that dilemma between memory and commodification: what for some is an economic opportunity and visibility, for others is the trivialization of a tragedy that is still alive. He crime tourism It grows, and with it the ethical question that accompanies it: how much knowledge and how much morbidity there is in looking head-on at the scenes of horror.

Years ago Alicante opted for an artificial island with a luxurious restaurant and taxi boat. It hasn’t turned out as I expected

November 6, 2025 by usatoday24

The idea was good. AND on paper It was fable. Set up a restaurant an artificial island in the heart of the port of Alicante, a benchmark in the Valencian hospitality industry where people could eat paella or have a drink with views of the Mediterranean (directly on it, rather), surrounded by sailboats. So that clients could reach the island, it was even thought to build a taxi boat. The idea sounded so good, in fact, that the Port of Alicante decided to invest heavily in it, dedicating millions of euros to it. Now instead of an idyllic island to drink mojitos and coffees in the middle of the mouth what it has is a huge mess. An artificial island? That’s how it is. To understand it you have to go back a few years, to beginning of 2022when the Alicante Port Authority awarded Vías y Construcciones (subsidiary of the ACS Group) one of its most ambitious projects, at least as far as the interrelation between the docks and the city is concerned. What the Port entrusted to the company was the construction of a large platform at the mouth of its inner dock, a sort of artificial island of 669 m2 (34.8 x 20m) that would be supported with the help of three large 14 m concrete piles anchored to the seabed. The contest was launched with a budget of 2.7 million (taxes apart) and aroused the interest of several companies. The AC Group firm ended up imposing itself on the rest with a project of 2.1 million. And what did they want it for? The platform was just a means, not an end in itself. Its objective was to support a future restaurant located in a privileged enclave, a place that would offer food and drinks not with views of the sea (many bars in Alicante already have that) but directly over the sea. If the island measured 669 m2, the idea was that the building dedicated to hospitality uses would occupy 393 m2 on the ground floor and rise two levels (ground and first floor). The remaining 260 m2 would be dedicated to public access, with a three-meter wide promenade. So that people could reach that privileged enclave, it was also planned a taxi boat. The idea was once again ambitious: a purpose-built, sustainable boat managed directly by the restaurant. Did it stay in theory? No. The Port of Alicante took important steps to make the project a reality. The main one was the awarding of the works for the island platform, which ended up being erected, as can be verified today on the docks. The problem is that what should have been a simple work in theory ended up becoming complicated in a bad way, as recently recognized the Port itself. In 2023 one of the support pillars partially sank, requiring reinforcement work to be carried out on the seabed. From there the project entered a loop that now threatens to condemn it. In fact, the Port insists that it “has never received” the work, which is why it has not considered it good. “Once the work was completed, the contractor company refused to carry out a load test that would allow its stability to be evaluated, as provided for in the contract, and as an essential procedure for the port to sign the acceptance of the work,” remember from the organism. What’s more, he claims to have a report of CEDEX (an entity linked to the Ministry of Transportation) that “strongly advises against” carrying out the tests due to “the high risk of collapse of the structure.” And now what? After years of the open platform crisis and after the latest CEDEX report, the Port has decided to make a radical decision. Its last Board of Directors has given the green light to activate the procedures to “resolve” the construction contract for the island. That is, the organism wants break the agreementsomething that has been communicated to those responsible for Roads and Construction. Now the company has ten days to present allegations. Once that period has passed, “and after years of technical and negative incidents”, the proposal will return to the Board of Directors, something that will probably happen before 2026. “In recent years the Port has commissioned audits and expert reports that confirm the irreversible deterioration of the structure and the impossibility of meeting safety standards to locate the restaurant proposed in the original project,” the organization argueswhich in its 2024 accounts already contemplated “impairment losses” of 2.7 million euros, which it has invested in the platform. Is there anything else? Yes. The Port does not only propose to terminate the contract. He also wants the original seabed to be “restored” to “recover the navigable conditions” that existed before the platform works. If the contract finally ends up being broken, it is not unreasonable to think that the conflict will reach court, but the Port Authority assures that it has already touched all possible sticks, so it sees “all avenues to remedy the situation exhausted.” Are there more affected? The Port of Alicante not only awarded the works on the platform. In April 2022 it launched another contest which completed the project with its second fundamental piece: the building that was to rise above the artificial island to act as a restaurant. The one selected for its construction and management was a business alliance between Alicante Gastronómica SL and Restaura Gestión Forty SL, which from that moment became co-protagonists of the project. In fact, they would not only be in charge of the building, an elliptical, glass-enclosed block with a large interior garden patio, a restaurant with views of Alicante and a terrace for cocktails. Another of its functions would be to assume the “maintenance and governance” of the taxi boat that would connect the island, a ship whose investment, precise Alicante Plazatook over the Port and was commissioned for 460,000 euros (taxes included). In January the organization started to try it. Now … Read more

Cover letters were a treasure for recruiters, until AI turned them into wet paper

November 5, 2025 by usatoday24

AI promised to speed up the processes of staff recruitmentbut after a period of intensive use of AI by both companies and candidates, it has been shown that It’s more broken than ever. Further proof of this degradation are cover letters which, although before the arrival of AI models were a clear differentiating factor, are currently worthless, as a study by Princeton University and Dartmouth College has shown. Cover letters made a difference. The study ‘Making Talk Cheap: generative AI and Labor Market Signaling‘ carried out by Princeton researchers analyzed more than 2.7 million proposals on the Freelancer.com platform before and after the implementation of the LLM text generation models to create these cover letters. Their conclusion is that, before using AI, attach a well-written and to show interest and knowledge of the position and the company to which one was applying, considerably increased the hiring options because the recruiters perceived that this was a very capable candidate. Now they are wet paper. However, as the use of AI tools to generate these cover letters has spread, the appreciation of quality has improved so that candidates in the top 20% of writing skills were 19% less likely to be hired, while those in the lowest 20% increased their chances by 14%. In other words, employers stopped associating a well-written letter with a competent candidate. This has meant that the differentiating factor that a well-written cover letter previously provided has disappeared, reducing the curve of possibilities between the best-trained candidates and those who are not so well-trained. Letters submitted before the LLM models had a better chance of being hired than those post-LLM AI makes hiring more difficult. The effect observed in cover letters has been extended to other areas of personnel selection, since AI distorts real capabilities of the candidates. It is true that its use increases the perception of quality of the candidates, but as the average quality of the group increased, companies began to trust less in the information provided by the applications. He study ‘Does AI devalue communication? Theory and evidence of entrepreneurship and contracting at a global level’ carried out by researchers at Columbia University and Yeshiva, found a similar pattern in selection and entrepreneurship processes: access to AI reduced the accuracy with which recruiters identified the best profiles to fill a given vacancy by between 4% and 9%. If everything is good, nothing is good. For decades, a letter well tailored to the offer served as proof of interest and commitment on the part of candidates. In labor economics, this is known as “signalling”: the candidate conveys their effort through the quality of the text. Generative models have thrown that signal to the ground. The meta-analysis ‘The role of artificial intelligence in personnel selection’ concluded that the automation of selection processes with AI is eroding the traditional signals of merit that were transmitted through cover letters, emails or applications received by the hiring and human resources departments. In that sense, while it is true that AI has democratized competition in the job search, it has also made genuine talent less visible. Who is behind the algorithm? The current degradation of those “clues” that allowed recruiters to locate the best talent, forces us to look for new ways to evaluate candidates. As and as they pointed From the technological employment platform Manfred, the use of AI has multiplied the number of applications, but the perceived quality has not improved at the same pace. For this reason, many companies are choosing to implement more practical tests and face-to-face interviews in their selection processes. That is, eliminate from the equation the presence of AI for the last stage of the selection process. The unknown of this practice is knowing how much talent has succumbed to AI resume filtering prior to that first face-to-face interview.

The “foodies” have turned the historic centers of Italy into hell, so the cities are getting serious

November 1, 2025 by usatoday24

Italy is at war. In a not so particular one that it shares with other countries and cities: the battle to stop mass tourism. He is trying with all his might through higher rates, entrance fees that they folded After initial success, a veto key boxes and even taxes on tourist dogs. Now, several cities have agreed on one thing: stop the ‘foodies’. As? Prohibiting the opening of new restaurants in historic centers. In short. Going through the historic center of any Italian city is like entering a culinary amusement park. There is not only restaurants wherever you lookbut these constitute a fair in which eye-catching posters appealing to tradition and artisans who prepare fresh pasta in front of the windows of the premises, like circus animals, are a constant. Now, cities like Rome, Turin, Florence, Palermo and Bologna have launched restrictions when opening new restaurants in their historic centers. Displacing the population. Although Italians love their traditional cuisine as much as anyone, they are getting tired of their city centers becoming theme parks. There are especially bleeding streets, like Via Maqueda in Palermo or Via del Pellegrino in Rome (to a lesser extent), which are basically a succession of premises. As he comments The New York Timeshundreds of new restaurants have opened over the last decade in just a few streets of those tourist spots, establishments that dress in tradition, but are not and displace the local population far from their homes. It is something that is seen in many other cities in the world in which the tourism is doing that the price of land rises in very specific points, also that of rents, and the locals see how traditional businesses disappear while others linked to that consumerism flourish. “We must protect the center”. In the case of Italy, the aim is to fight against gastronomic gentrification, which is replacing historical markets and local stores with businesses aimed at mass tourists, and they also want to protect the authenticity and daily life of citizens. But we also want to preserve tradition and diversity compared to more homogeneous or franchised models. Luisa Guidone, Councilor for Commerce of Bologna, comment that “the center must be protected, maintaining the mix of existing stores that allow citizens to have their daily experience when shopping.” Everyone makes their war. As we say, the prohibition or limitation on opening premises is not part of a national initiative, but rather of each municipality. In Palermo, new restaurant licenses have been expressly prohibited in emblematic areas such as Via Maqueda. In Florence, no new openings of bars, restaurants or any food establishments in more than 50 streets in the center and some peripheral ones. In the aforementioned Bologna, until June 2028, new projects aimed at commercial activities that want to open in the historic center and in Rome or Turin will be carefully studied. more of the same (especially around the Vatican). Then, there are exceptions. For example, Florence allows you to open establishments such as art galleries, bookstores or crafts, anyone that is not focused on mass hospitality. Not just food. But this goes beyond gastronomic gentrification. In it Corriete di Bologna we can read that the restrictions They imply that, until 2028, it will be prohibited to open new money exchange stores, call centers (which are telephone centers, Internet connection points and money transfer points) in the historic center, as well as “buy gold” or automatic cash machines.slot machine‘. Debate. Now, promoting something like this is complicated when tourism represents almost 12% of the Italian economy and the gastronomic tourism It is an important source of income. In fact, in the NYP article they include statements from tourists who only want to eat. Also those responsible for FIPE, the Italian Federation of Food and Tourism Companies, who point out that “sometimes, the Coliseum is an excuse for an American among a cacio e pepe and one amatriciana“In addition, it is criticized that each city is waging war on its own and there is no law promoted at the national level. In any case, as we said at the beginning, it is evident that Italy has a problem with this mass tourism that is displacing the population that really lives in those cities. Traditional businesses have closed or have been converted, going from selling useful foods for citizens to traditional dishes wrapped in a striking way for tourists. And finding the balance seems tremendously complicated.

OpenAI has turned ChatGPT into mainstream AI. In the business world the game is being won by its great rival

October 29, 2025 by usatoday24

Anthropic is nowhere near as well-known as OpenAI, but its AI model, Claude, is gaining traction almost unnoticed. Perhaps because he is doing it in a somewhat more opaque sector like that of companies. at least like this I pointed it out this summer a study by Menlo Ventures that certainly paints an interesting picture for this corporate AI war. Overtaking on the right. The data of that company venture capital companies reveal that at the beginning of 2023 OpenAI dominated the business segment with its AI models: it had a 50% share, when Anthropic barely had 12%. In July the situation had changed radically, and while OpenAI had reduced its share to 25%, Anthropic had managed to grow it to 32%. Source: Menlo Ventures. Companies bet on Claude. According to data from OpenAI itself, the company already has 800 million users. A small part of them already use a paid subscription, and that has allowed annual revenue to rise to $13 billion by 2025. Of them, 30% come from companies. Anthropic itself points out that revenues in 2025 will be about 5,000 million dollars – although they may end the year with 9,000 – but 80% of them come from business clients, whose number now amounts to 300,000. The difference is notable. The programmers, protagonists. The Menlo Ventures report further argues that there is one type of professional user that is especially important in those numbers: programmers. In fact, Anthropic’s market share among developers is 42%, while OpenAI’s is 21%. A priori and according to this data, the developers’ preference is clear: they like Claude more than ChatGPT—and specific products, Claude Code and OpenAI Codex—when it comes to programming. Source: Menlo Ventures. Companies pay more easily. This reality seems to make it clear that for business users the benefits seem to be clearer and that is why companies do not seem to have qualms when it comes to paying for subscriptions to these AI models. Not only in programming, but for example in legal or administrative departments is where ChatGPT or Claude can improve productivity and save work for professionals, who pay to be able to use these options without the limitations of free plans. Even Microsoft signs up. Anthropic’s reputation is making companies traditionally linked to OpenAI also want to start betting on its models. This is what happened with Microsoft, which in September announced that Claude would be available in the Copilot suite in addition to ChatGPT. Meanwhile, OpenAI conquers the ordinary user. OpenAI’s approach is quite different. Although it obviously has part of its business focused on companies, its latest movements are very focused on attracting the largest possible number of users. The launch of Sora 2 and its social network Sora, and the recent presentation of the ChatGPT Atlas browser – which of course can also be used by professionals – indicate this. But. The data that puts Anthropic in this excellent position among companies comes from the Menlo Ventures study, but this company is an interested party because one of the startups in which it has invested is precisely Anthropic. Not only that, it is a common criticism among Anthropic users that their models are comparatively more expensive than those of competitors like OpenAI. These conclusions from the Menlo Ventures study may therefore be subject to suspicion.

How wellness marketing turned a vegetable into a potion

October 28, 2025 by usatoday24

From time to time, the algorithm decides which will be the new elixir of eternal youth. He did it with him water with lemon, with coconut oil on an empty stomach, with shots of weed and with apple cider vinegar. Now it’s the beet’s turn. On TikTok and in wellness magazines is presented in format shot morning that promises energy, luminous skin, sports performance and—of course—preventing premature aging. But is it really the new miracle superfood or just another example of health marketing wrapped in scientific language? All part of social networks. In just a few weeks, the so-called beet shots —the traditional beet shots—sneaked into the breakfasts of influencers and wellness devotees. The nutritionist Itziar Digón, in an interview with Vogueargued that this vegetable is “anti-inflammatory, improves circulation and helps prevent premature aging.” His recommendation was simple: a small glass, about 250 milliliters of blended raw beets every morning, to “activate the production of nitric oxide” and strengthen the immune system. The proposal did not take long to go viral. On social networks, the story fit perfectly with that modern idea of quick and natural health: a miraculous molecule, a morning gesture and an almost immediate effect. The nitrates in beets, enthusiasts explained, are transformed into nitric oxide, which relaxes blood vessels and improves oxygenation. In practice, it promised more fluid circulation, less inflammation and extra energy to start the day. Under the promise. There is some truth behind fashion. Some studies —published in Frontiers in Nutrition either ScienceDirect— have seen that beet juice can slightly lower blood pressure or improve physical performance in certain cases, especially in athletes. Also Healthline explains that its red pigments, betalains, together with natural nitrates, provide a slight anti-inflammatory effect. Besides, according to WebMDthese compounds help reduce inflammation by removing reactive substances from the bloodstream and protecting cardiovascular health. In short, beets are healthy, rich in fiber, vitamins and minerals, and have real benefits for blood pressure and vascular function. However, it is one thing to include it as part of a balanced diet and quite another to believe that a morning shot will rejuvenate the body or strengthen the immune system. The other side The clinical studies are clear: there is no evidence that beets “prevent premature aging”, “reduce inflammation of the gut-brain” or “strengthen the immune system” directly. An essay collected in PubMed showed thatafter 13 weeks of regular consumption, no significant cognitive or metabolic improvements were observed. There is also no scientific basis to claim that it “detoxifies” the body. As we have explained in Xatakadetoxification is a function carried out naturally by the liver and kidneys; It does not blend in a blender. And, as if that were not enough, excess beets can have unwanted effects. According to Healthlineits high oxalate content can increase the risk of gout in predisposed people. So no, not everything natural is harmless. The pattern repeats. If the script sounds familiar, it is because we have already seen it with other express remedies. It’s not that beets don’t have benefits—they do—but because the discourse surrounding them exaggerates, simplifies, and generalizes. The mix of scientific jargon (“nitric oxide,” “microbiota,” “low-grade inflammation”) and aspirational testimonials builds an illusion of rigor that sells more than reality. Behind the craze for morning shots is something deeper than a vegetable smoothie: a culture that seeks quick, instant, and visually shareable results. In an environment dominated by immediacy, well-being becomes contained; and the content, an emotional commodity. The critical point. The beet is not the problem. The problematic thing is believing that well-being fits in a 250 milliliter glass. Incorporating it into your diet may be a good idea—because of its fiber, iron, and antioxidants—but it won’t magically make you age slower or make your cells work better. So, if you really want to take care of your body, it’s better to stick to the usual things: eat a variety of foods, move, rest and not believe everything that shines magenta in your feed.

A 4.4 million-year-old ankle has turned the history of bipedalism and everything we knew about our ancestors upside down.

October 24, 2025 by usatoday24

The origin of human bipedalism, the ability to walk on two legs, is one of the great debates in science today. For decades, scientists have wondered what the last common ancestor we share with us was like. chimpanzees and its characteristics. Now an ankle bone has ended up giving us the key we were looking for to rethink everything what we knew about our ancestors. The study. Published in Communications Biology and as the protagonist a 4.4 million year old ankle bone that belonged to a Ardipithecus ramidus. a hominid which was discovered in Ethiopia and which gives us many data about the history of human evolution. And this is because the conclusion is surprising: the ankle of this ancient hominid has surprising similarities with those of modern chimpanzees and gorillas. Something that makes us think that humans evolve from an ancestor similar to African apes, which makes us wonder about how and why we began to walk upright. The great debate. He Ardipithecus ramidusor “Ardi”, is essential in this case. It lived 4.4 million years ago and already displayed hominid characteristics, but combined primitive features such as a prehensile, ape-like big toe with human-derived features in the pelvis and skull. This is what suggests right now that an “early form of bipedalism” was used. The key is in the morphology of the talus, which in Ardi resembles that of African apes more than that of any other fossil hominin analyzed. The objective in this case is to know how our ancestors moved on the surface, but they also climbed trees vertically. This suggests that it made use of both early bipedalism and skills typical of arboreal life, placing Ardi in an intermediate position between Australopithecus and the great apes. And this bone is the fundamental key to knowing how the evolution to bipedalism took place. The challenge. This finding broadly challenges the traditional model of human evolution, which assumed that the last common ancestor with chimpanzees was a generalist and arboreal ape, alien to terrestrial life and bipedalism. New evidence indicates that humans most likely evolved from an African ancestor specialized in vertical climbing and also had plantigrade terrestrial locomotion. That is, with the soles of the feet completely supported like current gorillas and chimpanzees. A true hybrid between the two automotive models. The authors maintain that several lineages (humans, chimpanzees, bonobos and gorillas) share a past adapted to mixed life between trees and soil. The subsequent evolution of bipedalism would have been built on that basis, little by little modifying the anatomy and locomotor abilities to stop climbing trees and move on to what we now all use in our daily lives. Its implications. The morphometric data of the ankle of Ardipithecus demonstrate the presence of a structure designed to “push” when walking and improve balance, but without completely losing the ability to grip. The evolutionary process towards complete bipedalism was much more gradual and less linear than what had originally been proposed by experts. Furthermore, the most recent studies not only focus on the talus, but also on the metatarsus and pelvis, confirming that Ardi could walk upright during his short journeys and return to trees to climb and take shelter. This duality is key to understanding how our ancestors adapted to different environments and ecological pressures. What changes. The hybrid anatomy of Ardipithecus ramidus dismantles the chimpanzee ancestor myth, and presents a new branch on our human evolutionary tree. Far from being a rarity, Ardi represents an example of evolutionary transition and the complexities that may exist in the origins of our species. Thus, scientists propose abandoning this concept of a straight line in evolution and embracing an adaptive mosaic between different species.
