In the United States you can buy a gun in a supermarket, but a Roscón de Reyes with a surprise inside is illegal

January 4, 2026 by usatoday24

In the Western collective imagination there is a preconceived idea: that in the United States you can buy anything. And of course, that image from the series and movies of a character buying a gun in a grocery store without much problem (later we will see that in practice this reality has a lot of fine print) and the hodgepodge of different slogans such as “The country of opportunities” or “the land of the free” do not help to think otherwise. However, if you are in the United States these days and the homesickness hits you so hard that you want a roscón de Reyes, you are going to be in for a surprise: although you can buy this popular sweet in some stores, it has lost a good part of the magic of the true ritual of eating a roscón: that someone randomly (more or less, we do not judge your expertise when moving figurines with the knife that splits) touches the figurine. Because although in the United States you can find the “King Cake”, most stores don’t take the risk and put the figurine aside, so that you can put it inside. They do it to comply with the law and avoid fines since, scrupulously speaking, the roscón de Reyes as it is known in Spain is illegal. There are roscones and roscones. First of all, the traditional roscón de Reyes that is consumed in Spain is neither the only one that exists nor is it only consumed here: France and Portugal also have their respective galette des rois with puff pastry or Gâteau des Roiswith almond cream and a figure. In Portugal there is the Bolo Rei with candied fruits and dried fruits. This European celebration was exported to America, adapting with other flavors and customs of each region. Thus, there are the Roscas de Reyes from Mexico, Colombia and Guatemala and there are also in the United States in the form of King Cakea popular candy in Louisiana for the Mardi Gras and also in Quebec, which has its own shades and glazes. In the case of the King Cake, the figurine in question was a baby that was once baked inside. In the past they were made of porcelain (“Frozen Charlotte”), but then they became plastic and generally, to stand outsideleaving the consumer the responsibility of hiding it inside before serving it, so there are those who who is disappointed. But it is better for a consumer to be disappointed than to face a fine or lawsuits. What the law says. The regulations that apply in this case are the Federal Food, Drug and Cosmetic Law (Federal Food, Drug, and Cosmetic Act or FD&C Act) in force since 1938. The section that interests us for this matter is in section 402where it details that “confectionery that is partially or completely embedded with any non-nutritive object is adulterated, unless the FDA has issued a regulation that recognizes that the non-nutritive object has practical functional value to the confectionery product and would not render it harmful or dangerous to health.” The most famous example is Kinder eggs. And spoiler: neither the bean nor the roscón figurine is considered to have any practical functional value. Worse than fines are lawsuits. The fine in question for disobeying the law and integrating the figurine into the roscón is moderately low (to give us an idea, that of smuggled Kinder eggs it’s 2,500 dollars), that is why over the years there have been bakeries that have dared to challenge the law, arguing that culturally, whoever buys a Three Kings roscón, you already know that there are objects inside. However, possible cases of suffocation or injuries such as breaking a tooth that lead to lawsuits can be much more expensive. So there are those who deliver the roscón alone, others who place a large warning label and the figure in a separate bag and in plain sightin places like in the center of the cake or sitting on it. This is the most common practice in industrial bakeries or supermarket chains such as Walmart. It is easier to buy a gun than a roscón with a figurine inside. Returning to the purchase of weapons from the intro, sales in physical stores are centralized in gun stores and large stores with a sports and outdoor section. In the case of Walmartthey have stopped marketing pistols and military rifles to focus on hunting rifles and shotguns and in any case, the process is the same: with a separate counter, specialized personnel, you must be 21 years old and you have to fill out the federal form 4473 accompanied by your identification and they will accompany you to the door to make sure that you do not take it out of the box there.

Europe is months away from registering a demographic milestone that has not occurred since the Black Death: it is literally shrinking

January 4, 2026 by usatoday24

In June the latest Eurostat data putting the EU median age at 44.7 years (and growing). The reading then seemed more or less clear. Europe’s demographic collapse was bringing it closer to an invisible threshold that was once unthinkable: the Middle Ages. 50 years old. Half a year later, the data has not improved. Historical contraction. Yes, Europe is heading towards a demographic turning point unprecedented since the black plague from the 14th century. After decades of sustained decline in birth rates, the population of the European Union will reach its maximum next year and it will start after a prolonged fallthe first of its kind in centuries. This is not a temporary adjustment, but rather a deep structural change that threatens to redefine the economy, the welfare state and the social balance of the continent. The alarm does not arise only from the total number of inhabitants, but from the aging speed and the thinning of the working-age population, on which the pension, health and care systems built over generations rest. Political panic and a race. counted the Washington Post that, given this panorama, governments of all ideological stripes have entered into a race against time to see if a combination of economic incentives, public policies and cultural messages can reverse (or at least stop) the decline in birth rates. In the Nordic countries, for decades exhibited as a model of conciliation and well-being, commissions of experts have been created to understand why their systems did not prevent the collapse of fertility. In France, the discourse has acquired a almost military tonewith calls for “demographic rearmament” after a drop of 18% in births in just ten years. In the east and south of the continent, especially in countries governed by nationalist forces, the response has been more direct: money, tax advantages and an explicit exaltation of the traditional family as a pillar of the nation. Incentives and results. Italy offers bonuses to working mothers with two or more children. Poland has increased notably the monthly transfers per child and has expanded tax breaks for large families. On paper, these policies seem compelling, even enviable from countries like the United States, where the cost of raising children is systematically cited as the main brake to birth. However, the European experience shows a repeated pattern: even the most ambitious programs barely succeed in slowing the decline, don’t invest it. The problem is not the lack of public effort, but the magnitude of the phenomenon they face. Hungary, the laboratory. No country better embodies the ambitions and limits of this strategy than Hungary. For more than a decade, the government has deployed a support system of a generosity comparable to that of Scandinavia, allocating around 5% of its GDP to family policies, a higher proportion than the United States dedicates to defense. The range of measures it’s wide: leave for grandparents, subsidized mortgages for young married couples, loans of up to $30,000 that become subsidies if the family has three or more children, and lifetime tax exemptions for women with three children, extended to mothers of two children under 40 starting next year. The message is clear: having children is not only desirable, it is a matter of national survival. Initial successes. They remembered in the post that for a time, the data seemed to prove this bet right. Hungary’s fertility rate went from one of the lowest levels in Europe to figures that suggested a sustained recovery. But the relief was short-lived. In recent years, the trend has been reversed and the country has practically returned to the European average. For some demographers, the program did not generate new births, but rather advanced decisions by those who were already planning to have children. Others point out that, although the impact on fertility is limited, the policies have coincided with an increase in marriage, a reduction in child poverty and greater female labor participation. The key question is whether these collateral benefits justify the enormous public spending. State limits. Beyond the checks and exemptions prosecutors, the decision to have children remains deeply personal and increasingly complex. The rise in housing prices, persistent inflation and job insecurity they weigh as much or more than any incentive. Added to this is a factor that is rarely recognized in the political debate: many of the drivers of the decline in birth rates are social advances that no one wants to reverse. Widespread access to contraception, decline in teen pregnancy, and increased education and career opportunities for women have transformed motherhood and fatherhood in a late choice, carefully calculated and, for many, expendable. Modernity as a trap. The fertility drop has spread so widely that many experts interpret it as a consequence inherent to modernity. Parenthood is delayed until one’s thirties, when one has achieved job and economic stability that comes later and later. Social media idealizes a life focused on the individual, travel, and personal freedom. dating apps multiply apparent options, but they make lasting commitment difficult. And a generation raised in small families has less daily contact with babies and children, fueling overly negative perceptions about the sacrifice involved in raising children. A politicized debate. Not everyone considers the population decline to be a tragedy. Some defend assuming it as a gradual transition towards more sustainable societies, questioning apocalyptic visions who talk about “demographic collapse.” In the long term, even in the most pessimistic scenarios, Europe would still have hundreds of millions of inhabitants. But these global figures hide a much more immediate structural problem: the imbalance between workers and retirees. In just a few decades, the ratio of people of working age to each elderly person will increase. will have drastically reducedputting under strain systems designed for a demographic pyramid that no longer exists. The fragility of immigration. For years, immigration has been presented as Europe’s demographic lifeline. However, this option is becomes more uncertain as fertility falls across almost the entire planet. Even countries that until now were large demographic reserves … Read more

Someone bet $30,000 that Maduro would fall the night before he fell. He has won $400,000

January 4, 2026 by usatoday24

Early on Saturday, January 3, a raid by the United States Delta Force broke into the Fuerte Tiuna military complex, located in the south of Caracas, to arrest Nicolás Maduro and Cilia Flores, the president of Venezuela and his wife. Shortly after, someone was looking at his account. Polymarket and he rubbed his hands: that same Friday he had invested $30,000 betting on Maduro’s departure. With his arrest on Saturday, he had obtained a profit of $436,759.61. How lucky. A new account and a lucrative “hunch”. Polymarket’s Burdensome-Mix account barely I was a week old on the PolyMarket platform, but in record time it became one of the most fervent and active in “predict”“ Maduro’s departure during the hours before the operation. In a few hours he had gone from injecting money when the bet investment was at bargain prices to skyrocket: his participation had obtained a total return of more than 1,333.33% and a profit of at least 1,233.33% more than what he bet in less than 24 hours. PolyMarket. Tyson Brody Many people may have been caught off guard by Maduro’s arrest, but it certainly wasn’t for everyone: there are people who anticipated events and earned thousands of dollars as a result. Whether for him pizzometer or looking at Polymarket and company, something was brewing. In fact, there are already those has developed a tool to track suspicious activity on Polymarket because yes, there are those who decide to invest in what Elon Musk will become president of the United States and throw away his money like that (spoiler: he is South African and the US Constitution vetoes the presidency to foreigners), but he has long since emerged as one of the best seers of immediate events. As explained one of the creatorsPolymarket API keys are available to everyone and from here, it’s a matter of analyzing new wallets, unusual sizes and repeat entries into certain market niches. Suspicious behavior like the one that took place on Friday, when his tracker flagged five different alerts hours before Operation Absolute Resolve happened. The market that was betting on Maduro’s departure rose strongly before 10 p.m. on Friday after being at very low figures during the previous weeks, as picks up The Wall Street Journal. Polymarket What has happened in Venezuela. Nicolás Maduro was captured by US special forces following Operation Absolute Resolve in an intervention that threatens international lawalthough the United States relies on its domestic jurisdiction. Yesterday he was transferred to Stewart Air National Guard Base, a military airport in New York, and later landed at the Metropolitan Detention Center in Brooklyn, where he will face trial for drug trafficking and weapons possession. Donald Trump gave the details of the operation at the relevant press conference ensuring that “We are going to govern Venezuela until there is a safe transition” and that after the operation, American energy companies will take care of Venezuela’s oil industry. The official White House rapid response support account published a video where Nicolás Maduro was seen detained, being escorted through a hallway while he congratulated the new year to the people who were in his path. Tap to go to the post The insider trading of the prediction market. The Polymarket user’s operation draws so much attention that it seems evident that he knew what was going to happen in some way, which closes the circle to spheres very close to the president insofar as neither Congress nor his Defense Committee knew about this operation (much less had they authorized it, as he complained the governor of New York State on Twitter). Needless to say, what is known in financial markets as insider trading (trafficking of privileged information) It also happens in prediction markets like Polymarket, Kalshi either PredictIt and it is not only that it is allowed, but it is an ecosystem that favors it: Polymarket accounts are anonymous, global and transparent using technology from the blockchainso from there it is not possible to pull the thread of that lucrative operation.

The Polymarket phenomenon returns to its old ways. This is not the first time we have talked about Polymarket in terms of striking movements linked to politics, so Maduro’s thing is not something that is new.

Polymarket and company are not a mere betting platform like those for sporting events, but they have changed the discourse from betting to investmentwhich affects both linguistics and regulation. Thus, they are defined as “event contracts”, which allows them to sneak into the traditional financial system with the approval of leading players in the sector. like the owners of the New York Stock Exchange. The idea on paper is simple: as a user, you can express your opinion by buying or selling shares in eventual outcomes of events in operations executed between peers using smart contracts.

the first pilot line to recycle rare earth magnets

January 4, 2026 by usatoday24

Europe has learned an uncomfortable lesson in recent years: the energy transition does not depend only on political will or investments in renewables, but on materials that it does not control. After achieving —not without difficulties— reduce its dependence on Russian gas, the European Union is facing now to a deeper, more structural vulnerability: China’s near-absolute dominance over critical metals and, in particular, rare earth permanent magnets. Without these magnets there are no electric cars, no wind turbines, no advanced robotics, nor much of the defense industry. However, France has taken a step that goes beyond political discourse and can turn the tables. The inauguration of a pioneering pilot line. The Orano group and the Alternative Energies and Atomic Energy Commission (CEA) inaugurated at the CEA-Liten facilities in Grenoble, a pilot line dedicated to the recycling and remanufacturing of high-performance permanent magnets from rare earths. As Orano explained, The infrastructure has a pilot capacity of up to four tons and is equipped with technologies representative of an industrial scale, operated by a joint Orano–CEA team. The technical results of the project are expected by the end of 2026, with a view to subsequent large-scale implementation by an external industrial operator. A response to a critical dependency. The importance of the project goes far beyond its technical dimension. Permanent magnets based on neodymium-iron-boron have become key pieces for the European industrial future, but today the EU matters more than 95% of those you need. and the demand it doesn’t stop growing: The market has grown from around 250,000 tonnes of magnets this year to around 350,000 in 2030, with a growing proportion of high-performance applications. The problem is not only volume, but control of the value chain. China not only concentrates a good part of the world reserves of rare earthsbut between 70% and 90% of its processing and up to 99% in the case of heavy rare earths. This gives it a capacity for geopolitical pressure that has already translated into export restrictions and real supply interruptions for European industries. In this context, the Grenoble pilot line is fully part of the Critical Raw Materials Actwhich sets the goal that at least 25% of critical raw materials are recycled in Europe by 2030. “Short circuit” recycling. This is what the technological core of the project is called. Unlike traditional recycling – the so-called “long loop” – this approach allows rare earths to be recovered directly in metallic form from magnets at the end of their useful life, without going through complex chemical steps of dissolution, reoxidation and reconstitution. “This recycling offers an optimal compromise between magnetic performance, circularity and decarbonization,” explains Benoît Richebé, project manager for Rare Earths and Magnet Recycling at Orano, in statements collected by El Periódico de la Energía. The approach allows critical metals to be directly reused and reconstructed new high-performance magnets, suitable for demanding applications such as electric vehicle traction motors or offshore wind turbines. Orano defends, however, a hybrid approach. According to Richebé, short loop and long loop recycling are complementary, and Europe must be able to have both to build a flexible and resilient industry. The mixture of secondary raw materials with new alloys ensures maximum technical performance. Beyond the pilot. Currently, the recycling rate of rare earth magnets in Europe is just 1%, according to data cited by the German Mineral Resources Agency (DERA). For years, the combination of low prices for Chinese primary products and irregular availability of waste has slowed the development of a large-scale recycling industry. However, how RawMaterials collectsthe largest magnet recycling plant in Eastern Europe, operated by Heraeusand in the south of France the company Caremag plans to establish a rare earth recycling and refining plant in the coming years. However, here comes the key point: the Orano and CEA project is also supported by two collaborative consortia financed by France and the European Union —Magellan 1 and Magnolia 2—, which develop complementary technologies for the manufacture of magnets from recycled critical metals. One of the differentiating elements of the project is the application of Orano’s nuclear know-how to the magnets industry: powder metallurgy, processes in controlled atmospheres, sintering and management of highly regulated facilities. Experiences accumulated in plants such as Orano Melox, dedicated to nuclear fuel recycling, are now transferred to a key sector for electrification. A crack in the monopoly. France is not going to compete with China in production volume of rare earths or magnets in the short term. But with this pilot line, something perhaps more important has begun to be disputed: the control of industrial knowledge and processes. As Benoît Richebé summarizes“mastering the recycling of magnets will be essential for the ecological, digital and technological transitions.” It is not just about materials, but about industrial sovereignty. If the pilot meets its objectives and the processes are successfully transferred to an industrial scale, Europe could recover part of a value chain that it lost decades ago. In a world where critical metals have become instruments of power, recycling magnets is not just an environmental solution: it is a strategic act.

the projects that still keep the free and free web alive just as we dream of it

January 4, 2026 by usatoday24

The Internet has never had so many users or so much content, and yet it increasingly looks like a handful of repeated screens. Much of what we read, watch or search for goes through the algorithms of a few large platformswho compete for our attention and they convert many of our clicks into measurable data. In the midst of this standardized landscape, projects survive that operate with a different logic, such as Wikipedia, OpenStreetMap or the Internet Archivewhich are not financed by ads, do not sell detailed profiles of their users and continue to support a simple and demanding idea at the same time: that information and knowledge should be a shared good. The web did not begin as a showcase for large platforms, but rather a dispersed and almost artisanal laboratory. In the early nineties, those who published on the web They did it from university serversinstitutional or domestic, using open standards such as HTML, HTTP and URIs. They were fundamental pieces of a network designed so that information could circulate without depending on technological owners or closed systems. This technical architecture fueled the idea that the Internet could be an open and accessible space. The Internet was not born to sell data: the market found how to do it That enthusiasm, however, lived with obvious limits. As we say, participation was concentrated in universities, research centers and a minority of enthusiasts with technical knowledge and resources. The figures of the time show that just one minimum fraction of the world’s population had access to the Internet, which means that this supposed openness was real in technological terms, but not socially widespread. Starting in the mid-nineties, and especially at the end of that decade, the Internet began to receive more attention. Companies saw economic potential in a network that connected millions of people and allowed information and services to be distributed on a global scale. Commercial providers, popular browsers and the first portals emerged, and with them came the logic of the market: there was traffic, there were users and, therefore, there were business opportunities. Access to the web stopped being an experiment and began to become a massive, measurable and profitable activity. This change promoted a model that would quickly consolidate: segmented advertising. It was not just about showing ads, but about analyzing user behavior and obtain data about your interestshabits and preferences. It was the moment when human attention began to acquire a concrete economic value. Clicks, dwell time and browsing patterns ceased to be technical traces and became raw material for a new digital market. In this increasingly commercialized context, some projects maintained another way of understanding the Internet. They were not born to attract traffic or to compete for attention, but to build public information infrastructures. Wikipedia was launched in 2001 with a goal that seemed unrealistic at the time: to create a free, collectively written encyclopedia available to anyone with an Internet connection. OpenStreetMap began its journey in 2004 with a similar idea, but applied to the territory, collaboratively documenting the streets, roads and places of the world. Since 1996, the Internet Archive had been preserving pages, documents, audio and video so that they would not disappear over time. Two decades later, these projects are not only still active, but are central pieces of the current web. Millions of people consult Wikipedia every day to check a fact, understand a context or learn something new. OpenStreetMap maps power everything from mobile applications to public services and humanitarian projects. And the Internet Archive has become a long-term digital memory, a place where the web is not deleted, but preserved. They are initiatives collectively built that have achieved global impact without adopting the dominant business model. Wikipedia is supported by millions of small donors, most of them are readers who contribute small amounts, usually around ten euros a year. The Wikimedia Foundation manages these resources and maintains the technical infrastructure, including servers, software development and security systems. He also manages the Wikimedia Endowmentan independent fund created in 2016 to ensure that the project can continue operating even if revenue drops one year. Since 2021, there is also Wikimedia Enterprisea way for organizations that intensively reuse content, such as search engines or artificial intelligence companies, to access structured and stable versions of the data. Financed on the backs of the people OpenStreetMap has a different and much more decentralized structure. The OpenStreetMap Foundation is responsible for servers and general coordination, but much of the work comes from local communities organizing events, training and collaborative mapping tasks. The financing comes in the form of voluntary duestechnical sponsorships and support from organizations that use the data in logistical, humanitarian or educational projects. In the case of Internet Archive, the costs fall on an infrastructure that stores millions of pages, documents and files, financed through individual donations, grants from foundations and public organizations, and archiving and digitization services for institutions. When we talk about open projects, we can confuse openness with absence of organization. However, its operation is based on explicit rules and distributed structures. Wikipedia exemplifies this better than anyone. Editorial decisions are not made by a small group, but by thousands of people who apply public standards such as neutral point of view or verifiable content. The profile of the person contributing does not matter, but rather whether their contribution meets those criteria. Administrators can intervene to protect pages or resolve disputes, but their role is primarily technical and maintenance, with no hierarchical editorial authority over content. OpenStreetMap works with a similar logic, but on geographic data: the information is built from the local and is review collectively to ensure consistency. There are regional communities They coordinate tasks, organize meetings and define practices, but the base remains open. In the case of Internet Archive, the process is not so much editing as cataloging and preservation, and external collaboration focuses on improving the quality of records and avoiding the loss of digital documents.

a third of the world’s data centers are in a single country

January 4, 2026 by usatoday24

Currently there are more than 11,000 data centers operating worldwidewhich is said soon. Seeing the huge investment by technology companies, The figure is going to grow exponentially in the coming years. Now, thanks to the interactive map of Data Center Map We know where they are. An overwhelming majority of them are in the northern hemisphere, with one country accounting for almost a third of the total. United States rules USA To no one’s surprise, the country with the largest number of data centers is the United States. Considering that the major cloud infrastructure companies are American, this is also not surprising. In total they have 4,303 data centers spread throughout the territory, but not on a regular basis: there are regions in which the concentration is brutal. In the state of Virginia alone there are a whopping 668 data centers, which is more than Germany, the second country on the list with 494 centers. The weather too We already know that data centers consume a lot of energy and much of it goes into cooling their components. The hotter it is outside, the more it will cost to cool it and therefore the more energy is consumed, as well as water. According to the American Society of Heating, Refrigerating and Air Conditioning Engineers, The ideal temperature for a data center is between 18 and 27 degrees Celsius. Location has a notable impact on electricity and water expenses, which is why technology companies usually choose places with lower temperatures to set up their infrastructure. The south also wants its piece of the pie Indonesia It is striking that, despite the temperature recommendation, there are many data centers in countries where heat is a problem. Rest of World has done an extensive analysis about this phenomenon and estimates that at least 600 facilities are operating in areas outside the optimal range. In fact, following the list of countries with the highest number of data centers, we see that Indonesia is in third place with 184 facilities, followed by Brazil with 196. Both have a average temperature of more than 26 degrees, which means that for much of the year temperatures exceed that threshold. Singapore A striking case is that of Singapore, where the average temperature is more than 28 degrees. It has 78 data centers, a low figure compared to those we have mentioned, but they are concentrated in a very small area, which makes it one of the countries with a higher data center density. Other countries where demand for data centers is increasing are IndiaVietnam and the Philippines, all of them with quite hot climates. The heat challenge Why build in such hot areas? For many countries, data being within their own borders is more important than optimal operating temperature. The risk that arises is that, with the temperatures increasing year after yearwhat is now a manageable situation can become a difficult problem to solve, especially in areas such as Southeast Asia and the Middle East. They say in Rest of World that precisely in Singapore there is an initiative in which more than 20 technology companies and universities participate with one objective: to develop a refrigeration system Specific for humid and hot climates. The most common cooling system is air, but in these areas it is most effective to use a hybrid cooling system that uses air when possible and water when it is hotter. In some areas with extreme temperatures such as the United Arab Emirates, they are even considering build them underground. In China they are testing an even more radical solution: build a data center under the sea.

“You can’t trust your eyes to know what’s real anymore.” Instagram CEO announces that the feed is dead

January 4, 2026 by usatoday24

That the Internet as we knew it no longer exists is not a surprise: it has been filled with search results generated by artificial intelligence and from ‘slop‘. The consequences are already visible: clicks have been reduced by halfwhich is catastrophic for the media. But not only the text is suffering from this barrage of AI that blurs everything: already We do not know how to distinguish if an image is real or notwe have gone from document our life on social networks to the era of influencer content favored by the algorithm to videos and images that are not real, but can pass as such. There are no longer four fingers that are worth it. Instagrammers, the feed is dead. And this is also going to take its toll on social networks. Adam Mosseri, CEO of Instagram, closed 2025 with a publication in the form of a presentation of 20 images where he reflected in depth on what is coming: “the era of infinite synthetic content”, the antithesis of a more personal Instagram that has been dead for years. For Mosseri, AI has turned the carefully maintained grid with its algorithm into something of the past: “Unless you are under 25 years old and use Instagram, you probably think of the app as a feed of square photos. The aesthetics are careful: a lot of makeup, skin softening, high-contrast photography, beautiful landscapes,” Mosseri’s sentence falls like a stone on this millennial, who still uses Instagram as a kind of photo album. “That feed is dead. People largely stopped sharing personal moments on the feed years ago.” Tap to go to the post In search of something real. Mosseri explains that now its users keep their contacts up to date on their personal lives with “improvised photos of unflattering shoes and poses” shared via DM. And this also affects content creators: the omnipresence of images made by AI is going to bring a change: goodbye to those pro-looking photographs in favor of a more real and improvised aesthetic: “Flattering images are cheap to produce and boring to consume. People want content that feels real.” In fact, the CEO of Instagram points to manufacturers, applicable to cameras and mobile phones, who he says are making a mistake by democratizing the ability to “look like a professional photographer from 2015.” Because RAW images with defects are still a sign of reality until AI is able to copy them. But what is real? The time has come to unlearn to believe what our eyes see, something we have been doing all our lives. Javier Lacort explained that our entire epistemology (ranging from court testimony to photo albums) is based on the fact that seeing is a way of knowing. If you see a tiger, there is a tiger. If you see a photo of a tiger, someone has been close to one. This no longer applies: the era of uncover organized fake news has made way for anyone with Nano Banana Pro can get such an absurdly realistic image with a basic prompt in just a few seconds. Now creating a deepfake is trivial. Adam Mosseri think equal. “For most of my life I was able to safely assume that photographs or videos were largely faithful captures of moments that actually happened. That’s clearly no longer the case, and it’s going to take years to adjust. We’re going to go from defaulting to assuming that what we see is real to starting from skepticism. To paying attention to who’s sharing something and why. This will be uncomfortable: we’re genetically predisposed to believe our eyes.” If you can’t beat them… The paradigm shift has already occurred, so now Instagram and other platforms have to adapt to this new reality: “we have to build the best creative tools. Label AI-generated content and verify authentic content. Show credibility signals about who is posting. Continue to improve the ranking of originality.” It is the apocalypse of what is a photo that we have been predicting for years. Focusing on Instagram, Mosseri talks about how “we like to complain about ‘AI junk content,’ but there is a lot of amazing content created with AI.” He doesn’t give concrete examples or talk about Meta tools to make this possible, but Meta has already added AI tools on Instagram and Facebook. Without going any further, his AI Studio allows you to create personalized chatbots to deal with your followers. New times, new identification measures. It is increasingly difficult to identify content in AI, so it proposes fingerprints and cryptographic signatures in cameras to identify real content, forgetting about labels or watermarks. In any case, it advocates greater transparency about who publishes on the platform and improve creativity so that its human users can compete with content made in AI.

For more than a decade, the world became accustomed to an idea that seemed unquestionable: batteries—the heart of electric cars, of renewable energies, of data centers and of modern warfare— would be increasingly cheaper. China mass-produced them, dominated the technology, controlled critical materials and accepted minimal margins, even losses. For the West, the model was comfortable: import, reduce costs and accelerate the energy transition. That normality, however, has begun to crack. A turning point in the Chinese market. In recent months, several lithium battery manufacturers have begun to announce price increases after almost three years of fierce competition and below-cost sales. According to South China Morning Postthe most visible case is that of Deegares, which reported an increase of 15%, opening a debate on whether the sector is beginning to emerge from the “involution” cycle, a dynamic in which producing more, selling cheaper and earning less had become the norm. The immediate trigger has been the rise in the price of lithium, which has risen around a 70% from its annual minimum. This rebound responds to several overlapping factors: the rise of data centers for artificial intelligence, a rebound in demand for electric vehicles in China and an increasingly explicit intervention by the State to organize the sector. The Chinese Ministry of Industry itself has gathered to the main market players and has promised to accelerate measures to stop the so-called “irrational competition”. A stressed model. Sales prices for energy storage systems in China have plummeted by up to 80% in just three years. Some companies operate with gross margins of 15% to 20% in the domestic market, a far cry from the 40% or 50% common in the United States. The real profitability, analysts cited by SCMP admitwas in exports. And exporting, China has continued to dominate. This year it has managed to sell lithium batteries worth more than $69 billion. According to the analysis of energy expert Gavin Maguire in Reutersthis milestone is explained by the voracious hunger of Germany and the United States for large-scale storage systems, essential to stabilize electrical networks saturated by renewables and data centers. In practice, every new AI data center in Europe or North America starts with a silent dependency: thousands of batteries designed, manufactured and assembled in China. The low price hid an uncomfortable reality. All this time there was a truth that no one said out loud, perhaps because it was so obvious: there was no real Chinese alternative. This new year 2026 will be marked by the massive expansion of data centers that power artificial intelligence, facilities that consume amounts of electricity comparable to that of a small city and that need large-scale batteries to guarantee a continuous supply. Google has installed more than 100 million lithium-ion cells in its data centers, while Microsoft plans to eliminate diesel generators before 2030, replacing them with batteries to meet their climate goals. The forecasts confirm that the risk is not theoretical. The International Energy Agency sums it up crudely. If in 2024 China manufactured 99% of the world’s LFP cells and refined most of the critical materials such as lithium and graphite. For its executive director, Fatih Birol, depend on a single country For a strategic technology, it is a risk comparable to that posed to Europe by its dependence on Russian gas. The Chinese adjustment. Far from retreating, Beijing now seeks to organize the sector without losing its dominance. State intervention translates to braking the most extreme overcapacity, review mining licenses, limit sales at a loss and allow prices to rise to sustainable levels. The objective is not to make batteries abruptly more expensive, but to prevent a strategic industry from self-destructing by competing with itself. Control of raw materials remains the central lever. China process around of 80% of the world’s lithium and produces nearly 90% of the anodes and electrolytes used in batteries. When the United States or Europe impose tariffs, China responds by restricting exports of critical metals. The message is unmistakable: the power lies not only in making batteries, but in controlling every link in the chain. The Western Response. In parallel, the United States and Europe are trying to react. According to Sprott’s reportWestern governments have begun to treat lithium and batteries as strategic assets. Washington has invested directly in mining projectshas multiplied the number of planned gigafactories and has included restrictions on the purchase of Chinese batteries in defense legislation. Europe is following a similar, albeit slower path, supporting local extraction and refining projects and seeking to reduce its dependence on China. Big oil companies like Exxon either Chevron have entered the lithium business, and countries like Germany finance domestic production to ensure supply and reduce geopolitical risks. Still, the consensus among analysts it is clear: replicating the Chinese model will take years. Environmental regulations, labor costs and the absence of centralized industrial planning make competing on price impossible for now. Decoupling, if it comes, will be slow, expensive and politically uncomfortable. A planned domain. It is the direct result of the plan Made in China 2025with which Beijing decided to stop being the world’s cheap factory to become a technological leader. China already dominates solar panels, wind turbines, electric vehicles and lithium batteries. In addition, it controls strategic minerals such as graphite and has vertically integrated the entire value chain. In fact, the Asian giant It is the first “electrostate” in the world: a power whose power is no longer based on oil, but on renewable gigawatts, electrons and batteries. This strategy has reduced its emissions, weakened petrostates and turned its energy industry into a tool of global influence. The true cost of batteries. For years, this low price allowed us to accelerate the global energy transition, but it also created a deep and silent dependency. Now that China begins to organize its market, raise prices and prioritize its own industrial strategy, the world begins to discover the real cost of having delegated the heart of its energy system.

There is an age at which we should stop drinking alcohol forever. Neuroscience is clear why

January 4, 2026 by usatoday24

For years, popular culture and certain observational studies have sold us a comfortable idea: moderate alcohol consumption could be harmless and even beneficial for the heart. However, when we focus on the brainthe story changes radically. It is neurotoxic. A growing stream of neurologists and new epidemiological evidence point to an uncomfortable reality: alcohol is a neurotoxinand there is a biological age from which our brain loses the ability to tolerate it. Although official guidelines do not prohibit retirees from drinking, scientific literature suggests that The ages of 65-70 mark a critical boundary. Crossing it with a drink in hand could be accelerating cognitive decline and dementiawhich are very prevalent diseases at that time of life. Although there are exceptions, with people who are very long-lived and point out that their ‘secret’ is having a glass of alcohol daily. Although genetics may play an important role here. The neuronal reserve. Neurologist Richard Restak popularized a strong clinical recommendation: you should stop drinking completely at 70 years old. Is it an arbitrary number? Not at all. It is based on the concept of “neural reserve”. According to science, a young brain has room for maneuver before the arrival of these toxins. It has enough neurons and plasticity to compensate for the slight damage caused by ethanol, but, however, natural aging leads to a loss of neurons. That is why drinking in old age is, basically, burning fuel from a tank that is already in reserve and that is not going to be refilled. It is accelerating. Science in this case is quite clear that alcohol-related brain damage along with intense and prolonged consumption accelerates brain aging. And the fact is that with the same alcohol consumption, an aged brain has greater damage than a young one. Something that is explained because the neuronal repair mechanisms are also aged and do not have the same capacity as when a person is 20 years old to compensate. The data. The biggest blow to the idea that a little drinking “doesn’t hurt” comes from large cohort studies, such as the famous Whitehall II studiowhich followed thousands of people for 23 years. In this case, it was seen that people who drank between 14 and 21 glasses of alcohol per week were three times more likely to suffer from hippocampal atrophy compared to those who did not drink. And this is the fundamental region to have memory. For those who exceeded 30 units per week, the probability of atrophy shot up to almost six times more. But the most worrying thing is that no protective benefit was observed in the light consumption group (less than seven drinks a week) compared to general abstinence. Zero alcohol. These data along with brain imaging studies They point out that even ‘moderate’ consumption is associated with a significant brain alteration. This means that it can be stated that the safety margin for the brain is practically non-existent. The limit age. Why can 65 be a turning point? Although there is no international “dry law” for people over 70, organizations such as the Alzheimer’s Society from the UK warn that those over 65 are a special risk group. This is because there is already an aging liver that processes alcohol slowly, which means that the alcohol circulates through the body for longer. This is also added to the interactions that alcohol has with medications that can increase its toxicity and most importantly: increases the risk of dementia. You have to be careful. With all this data, science is quite clear that any consumption increases the risk of health problems, especially in regards to the brain. Although clinical guidelines still recommend simply “not exceeding 14 units per week,” the recommendation of experts like Restak and reading the most current evidence suggest a more aggressive prevention strategy. Given that we have no cure for dementia and that neuronal reserve is our only shield, giving up alcohol when entering old age is not an option, it is a logical cognitive survival strategy.
