China has just resolved one of the biggest doubts about going to Mars with the birth of six space mice

by

For years, the great doubt of space biology It has not been whether we can have tomatoes and lettuce in orbit to be able to populate other planets, but whether our bodies will remain functional after returning from the vacuum of space. Something that above all interests us in order to reproduce. And in order to solve it, China sent a mouse who was in the Tiangong station to see if she was later capable of having babies and if they came with any serious alteration. Some babies for history. The result of this trip to Tiangong Station The truth is that it has been a successsince on December 10, 2025, a laboratory of the Chinese Academy of Sciences (CAS) witnessed an apparently everyday but scientifically extraordinary event: the birth of nine baby mice. The special thing, logically, was not the birth, but the fact that his mother had been in space for several weeks (although with some problems) subjected to microgravity and cosmic radiation. Now, six of these babies have survived and are growing normally. It was not without incident. The experiment was a priori quite simple: launch four mice (two males and two females) into space on October 31 and leave them there for two weeks. All this accompanied by adequate food for the duration of the mission. But in the end there were major problems that forced extend the stay in space. And this was a huge inconvenience, since the critical shortage of solid food for the mice could literally cause the mice to die and the mission to be a disaster. And that is why on Earth they began to look for the most suitable food to feed these animals and the result was liquid soy milk, which was the only thing available at the station. Completely monitored. In order to have good traceability of what the mice do in space, scientists kept the mice monitored with artificial intelligence at all times. In this way, it was possible to know at the moment what they ate and even the stress patterns they presented, circadian rhythms and possible anomalies in real time. And everything was taken care of in detail, to the point that the soy milk was supplied with a negative pressure pumping system to prevent liquid bubbles from floating around the cabin. The progression. Once this problem was resolved, on November 14, 2025, the animals returned to earth and natural conception occurred. The result was that 9 calves were born and only six survived in good health. The problem of microgravity. Until this experiment, there was a well-founded fear in the scientific community: that ionizing radiation and the absence of gravity would “break” something in the hormonal axis or in the integrity of the DNA of the gametes. Something that would prevent us from reproducing normally, which would prevent, for example, the colonization of Mars. Precisely, cosmic radiation acts as a shower of high-energy particles that can cause double-strand breaks in DNA. On Earth, our atmosphere protects us, but at 400 km altitude, mice (and humans) are exposed to a much higher dose. Researcher Wang Hongmei highlights that the fact that the offspring are viable suggests that the cellular repair mechanisms of mammals are capable of compensating for the damage suffered during short-duration flights. A competition. As with everything related to space, there is a great rivalry between the United States and China. In this way, if we look back we see that China He had already managed to partially develop mouse embryos in space in 2020. Subsequently, NASA in 2019 conducted researchers on the International Space Station to analyze the bone density loss and muscle in space. What’s next. The experiment does not end with childbirth. Now, scientists monitor what they call “second-generation effects.” The aim is to determine if these six mice will develop health problems in the medium term or if their fertility will be affected when they reach maturity. In this way, if these mice do not present infertility, we can see that space travel is not a sentence of sterility. China’s next big step will be to attempt the reproductive cycle in orbit: conception, gestation and birth without setting foot on Earth. Something that will be fundamental for to be able to understand if humans in space can have some kind of possibility of reproducing without the protection of our beloved atmosphere.

The runaway price of RAM threatens more expensive phones than ever. And that’s not even the biggest problem

by

Neither the car nor the house, the new indicator that someone is good pasta is the RAM memory that you have available. The RAM crisis is extremea price increase planned for 2026 that will hit the entire industry. Such is the seriousness of the matterthere are already those who predict that the manufacturers of telephones are considering returning to figures of the past: the 4 GB of unified RAM for smartphones of the next year. Samsung has doubled the price of DDR5 RAM after running out of stock, a movement that completely threatens the entire smartphone industry. And no, RAM is not just an element to ensure the fluidity of the mobile phone and efficient multitasking: RAM is a pillar on which the advancement of technology itself depends. How to know the components of your PC (RAM, Graphics, CPU…) and the state they are in The rise in prices. In just six months, RAM prices have skyrocketed between 100% and 400%. Giants like Samsung and SK Hynix are allocating around 40% of its resources to supply RAM to Stargatethe OpenAI infrastructure. Consequence: the RAM market has entered a valley of scarcity. The 4 GB of RAM. There are clear pillars for not recommending a phone even to my worst enemy: That it does not have good update support. That has a processor that can’t handle basic apps. That has less than 6 GB of RAM There are already those who predict that 4 GB of RAM will return in 2026a significant leap back even for entry-level devices, where 6GB of RAM was starting to become the standard. What they didn’t tell you about RAM. Advances in RAM go far beyond basic performance in multitasking and everyday apps. RAM memory is one of the vital organs of any smartphone, and the advances in it are what have allowed us, today, to have smartphones that are much more capable than those of years ago. Local AI processing– Without sufficient RAM, it is not possible to run local AI models. He iPhone 15 is the best example. Photographic quality: functions such as processing HDRcomputational zoom, and even the processing of the photograph itself (subsequently processed RAW data) depend largely on the mobile phone’s ability to move all that data in RAM. Exactly the same applies to video recording. Multi-window and multitasking: Multitasking is not just about not having a heavy game crash while you browse in Chrome. It’s that Google Maps can run in the background without slowing down your phone, that YouTube can run in mode PiP (window), that your keyboard is capable of managing translations and corrections in real time in any heavy app, etc. Gaming experience: We usually focus on CPU and GPU when thinking about a mobile phone capable of running a heavy game, but RAM is essential to avoid microcuts, speed up loading times despite having open apps, and ensure that the game will not close in the middle of a game. The consequences. We have been complaining for the last few years that there is hardly any real progress in smartphones and that, perhaps, we are close to their peak. But there are nuances in this interpretation. We have never had humble mobile phones with AI implementation, the ability to move triple A games on budget devicesand such a positive experience in practically any product range. The RAM crisis is a major brake on the advancement of upcoming proposals, and may make it more than likely that some 2026 phones will end up performing worse than their predecessors. There is no solution in sight. DDR5 RAM, although it has been on the market since SK Hynix released it in 2020is not common in entry-level proposals. DDR4 RAM is still the standard here and, unfortunately, so is its price. has been increasing by close to 200% in recent months. More expensive RAM, more expensive mobile phones or mobile phones with less RAM. Image | Xataka In Xataka | How to know how much RAM you have and what type it is, in Windows, macOS and GNU/Linux

Ukraine’s biggest problem is not Russia. There are three European countries trapped in a perverse mechanism: type C accounts

by

Europe faces a decision that goes far beyond an accounting discussion and that defines its strategic credibility: what to do with the more than 210,000 million of euros of Russian assets frozen since the beginning of the invasion of Ukraine. The problem is twofold, because it is not just about figures, but about what comes after activating the operation. The European crossroads. Yes, because the question is not only whether that money should be used to support kyiv at a critical moment, but whether the European Union is capable to take the risks political, legal and economic implications of doing so. As Washington presses for a quick exit to the conflict and reduces its financial support, Brussels finds itself caught between the urgency of avoiding a Ukrainian defeat and the fear of unleashing a russian retaliation that directly hits several of its Member States. Putin clearly. Statements this week by Vladimir Putinloaded with contempt for European elites and confidence in a protracted war, are not simple rhetoric. Moscow makes it clear that it is not contemplating real concessions and that it considers the use of its frozen assets as theft that demands a response. That response would not be symbolic, but surgical: selective seizures, accelerated nationalizations, endless litigation and the use of the Russian financial system as a weapon. The message, a priori, is unequivocal: if Europe crosses the line, Russia will not only punish Ukraine on the battlefield, but also European countries that still have exposed economic interests within their territory. The real blockage. I remembered this morning the financial times he crux of the whole situation. Although the debate is presented as a struggle between hawks and cautions, the real blockage comes from a handful of countries specific, with Belgium, Italy and Austria at the head. It is not a question of ideology, but of direct vulnerability. Belgium hosts Euroclear, the warehouse that guards most of the frozen Russian assets, and fears becoming the first target of retaliation judicial and economic. Italy and Austria, for their part, maintain banks and companies with billions trapped in Russia, benefits included, which they cannot repatriate. For these countries, authorizing the use of Russian money is not an abstract foreign policy decision, but rather an immediate risk to their financial and corporate systems. Type C accounts: the ace of Moscow. At the center of this fear are the calls type C accountsthe mechanism created by Moscow to withhold dividends, interest and assets from Western companies. That money, formally owned by European and American companies, is under Russian control and can be frozen, redistributed or directly transferred to the state budget with a simple decree. For the Kremlin, these accounts are a retaliation tool fast and effective, far superior in agility to slow Western judicial processes. For Europe, they are an invisible chain that binds entire governments when making strategic decisions, because any false step can translate into lost billions and internal political crises. Germany pushes, Europe hesitates. Germany has become the main political engine of the plan to use Russian assets, convinced that without that money there is no realistic way to support Ukraine for another two years without skyrocketing the European debt or depending on impossible unanimity. Berlin insists that the risk must be shared among everyone and that failure to act would send a devastating sign: Europe is not capable of defending its own security. However, this logic collides with the reality of countries that feel that the risk is not distributed, but rather concentrated in their national balance sheetsits banks and its courts. A (bad) peace as a threat. This financial blockade occurs in an even more disturbing context: European fear to an imposed peace on terms favorable to Russia. For many capitals, an agreement that consolidates Moscow’s territorial gains would not only leave Ukraine defenseless, but would force Europe to prepare for a scenario direct confrontation in the medium term, with longer borders, a strengthened Russian army and a weakened European deterrent. In this framework, the frozen Russian money stops being a tactical lever and becomes a strategic investment: either it is used now to support Ukraine, or it is paid for later in the form of massive rearmament and risk of war. The final dilemma. In short, the European Union has frozen Russian assets to prevent them from returning to Moscow without reparations, but now it must decide whether it dares to give the next step. Without that money, Ukraine could run out of liquidity in a matter of months, losing all negotiating power and forcing a deal from weakness. With him, Europe is exposed to reprisals, litigation and immediate economic losses, concentrated in a few countries that are currently holding back the decision. The crossroads are clear: assume the political and financial cost now, or accept that the fear of type C accounts determine European security policy. Not only the future of Ukraine is at stake in that election, but also Europe’s ability to act as a coherent geopolitical actor when your own interests are at risk.

is to have become one of the biggest attention grabbers in history

Even though the accounts at OpenAI are not so healthy as Sam Altman would likeit’s really not being a problem for continue raising money from your investors. The rain of millions being spent on ChatGPT It draws attention for the way in which they seek to obtain a return: through the attention of users. And it makes more sense than it may seem at first. 7,000 million visits per month. A recent analysis by Similarweb about generative AI has put very interesting figures on the table that are very useful for us to measure the pulse of the internet of our days. In September 2025, AI services added 7 billion visits per monthwhich represents a growth of 76% compared to the previous year and crowns AIs as one of the main rivals of social networks in terms of traffic. ChatGPT remains the undisputed leader: in the aforementioned month it reached 5.9 billion visits, very close to Instagram, with 6.5 billion. The first positions are for Google (with 82.6 billion), YouTube (28.7 billion) and Facebook (11.4 billion). All for our attention. In the age of the Internet, there is something more valuable than money itself: capture users’ attention. It is the reason why social networks are so attractive for companies of any size, becoming more of a commercial showcase that is a place where we can tell our lives. Also, this is the same reason why chatbots are still around, even though they lose money every time someone uses them. Meanwhile, big technology They are resorting to debt. They don’t want to be left out of the AI ​​bubble and the reason is now clearer than ever. The “backbone” of the internet. Not only has ChatGPT managed to become the fastest-rising platform in modern digital history, placing itself on the podium of the five most important websites in the world. The truly important thing about this is that they have managed to capture the most valuable thing: the user’s attention. The next step: fill the ‘chatbots’ with ads. Faced with this paradigm, OpenAI is considering something that was already an open secret: dress up ChatGPT with ads. A possibility that would serve to monetize the tool, especially to obtain financial returns from users of the free plans, but which raises many doubts in the field of privacy and the neutrality of the answers offered. Benefits for when? While, technology companies continue to increase investmenteven if the benefits do not come directly. The bonus, in this case, comes in the form of meteoric growth and several billion views that show that there is a reason to be optimistic about AI.

Now their biggest challenge is to convince Beijing to let them use them

by

China is experiencing an unexpected situation in the midst of the race for artificial intelligence: the country’s big technology companies want access to the chip NVIDIA H200but this time it is not Washington that sets the pace, but Beijing. The American government has opened the door to its export under clear conditions, although the final permit now depends on China, that has been tightening its policy for months on foreign semiconductors. Alibaba and ByteDance move in this delicate balance, aware that their ability to advance in AI in the immediate future will depend on what their own regulator decides. Two giants with enormous needs: Alibaba and ByteDance are not simple technology companies, but two of the companies with the greatest demand for computing capacity in China. Alibaba maintains an e-commerce network and cloud services that centralizes a good part of the purchases and sales that go through Taobao, Tmall or AliExpress, both in China and abroad. ByteDance operates TikTok and its Chinese version, Douyin, in addition to maintaining Doubao, its own AI chatbot. This combination of platforms with massive loads turns each jump in power into more than just a technical improvement: it conditions their ability to keep up with the pace of the sector. The change of course in Washington: On December 8, President Donald Trump announced that the United States would allow H200 to be exported to “approved customers” in China, a move that marked a turn from previous restrictions. The agreement contemplates that the US government receives 25% of the income from these sales, above the 15% applied to H20. The White House presented the decision as a formula to strengthen domestic manufacturing and sustain high-skilled jobs, while maintaining direct control over the flow of chips to China. Where the H200 fits into the NVIDIA lineup: The H200 belongs to the Hopper architecture, presented in 2022, and occupies an intermediate position between the generations already established in the market and the new Blackwell line, which is NVIDIA’s priority today. Blackwell-based servers can achieve tenfold performance gains on certain models compared to systems using H200, according to recent company data. Still, the H200 remains a relevant product for advanced training, especially in markets where access to newer hardware is restricted by export controls or limited supply capacity. NVIDIA H200 Why the H200 makes such a difference: The distance between the H200 and the H20 is still notable. According to the Institute for Progressthe H200 achieves a total throughput of 15,840 TPP, almost six times more than the 2,368 TPP of the H20. Compared to the most advanced domestic chips, the gap continues. He Huawei Ascend 910C It reaches 12,032 TPP and offers a memory bandwidth of 3.2 TB/s, while the H200 reaches 4.8 TB/s. That combination of power and speed explains why this chip is so coveted for training large-scale models. Alibaba and ByteDance have conveyed to NVIDIA their willingness to acquire large batches of the H200 if they receive approval from Beijing, according to information shared with Reuters by several sources. Chip availability is reduced because some manufacturing capacity is geared toward newer generations, increasing pressure on the purchasing window. In this scenario, both companies are trying to anticipate whether the Chinese regulator will allow a processor of this level to be incorporated into their training systems without additional restrictions. Access conditioned by the Chinese strategy: Authorization to purchase H200 depends not only on company demand, but on how it fits into the self-sufficiency goals set by Beijing. According to sources cited by the aforementioned agency, regulators are likely to demand precise details about the purpose of each order. In all this, it is no secret that China tries to accelerate the development of its own products through manufacturers such as Huawei and Cambricon, and any import of advanced hardware is examined in light of that strategic horizon. The situation leaves a market in which the rules seem inverted: chips like A100 and H100 They remain under export control, while the H200, more powerful and recent, could arrive in China under an exceptional framework. This asymmetry conditions the advancement of the country’s most ambitious models, which need competitive hardware to continue evolving. The outcome will depend on what Beijing decides in the coming days. Images | NVIDIA | Arthur Wang | In Xataka | Media China is talking about a feature of the ZTE Nubia M153.

One of the biggest wine critics is French and has toured China. There is no good news for French wine

by

TO Michel Bettane he likes wine. In fact, it is more than a hobby: he has developed a career around it, until it became one of the wine critics most influential in the world. For two decades he worked at ‘La Revue du vin de France’, a prestigious magazine that covers current events in the wine industry, until he decided to become independent and, together with a colleague from the magazine, founded the Betanne and Desseauve Guide. Bettane is one of the most authoritative voices worldwide in terms of wines and one with weight within the sector. He recently completed a tour of China in which has tasted more than 300 premium Chinese wines and its conclusion is as resounding as it is hurtful to French pride. The chinese wines They are superior to many of those found in France. And this guy doesn’t try cheap wines, but rather high-end ones. Chinese wines >> French wines These incendiary statements came after the sixth edition of the Bettane + Desseauve Wine Tasting in China. Held in Beijing and Shangri-La (Yunnan), the critic and five other international wine experts tasted more than 300 premium wines produced in China. Bettane has indicated that China is experimenting an “amazing awakening of the terroir”, and it is something that is not out of place if we take into account the international position of the country’s industry. If just 15 years ago it was a desert, now They are sneaking into the conversation like a power. The strategy of the Chinese industry is not to attack in quantity, but in quality, and for this there are wineries that have studied in the most powerful wine and wine regions in Europe to learn and then apply that knowledge to their field. Taking advantage of the particularities of each of its regions, there are wines that are becoming some of the most sought-after without having a French surname. Bettane stated that what has impressed him most is the technical precision when controlling the grape ripening and fermentation processes. “We found almost no wine with serious defects”he assured, adding that “the overall strength of the production standard is, in fact, higher than what we often find in our annual tastings in France.” It looks like a Scottish castle, but it’s a Chinese winery Above all, he highlighted two wine regions: Ningxia and Yunnan. We have already talked about Ningxia recently in Xatakaa very complicated area in winter for which they have developed a technique that consists of burying the vines so that the snow does not affect them. Those responsible have “copied” Bordeauxand it is something that catches the critic’s attention. The other is Yunnan, one that, he says, left him speechless. Especially for a white wine, a ‘Shangri-La Chardonnay‘ which, for Bettane, “can play in the league of the world’s great whites”. A wine strategy modeled on that of smartphones The interesting thing is something that the critic comments about the change in strategy of the Chinese producers, and it is something similar to what has happened in the technological world, especially with the smartphone industry. At first, as happened with Ningxia producers, they dedicated themselves to “copying” Bordeaux, but now Bettane has seen how are beginning to experiment and discover synergies between the grapes, the land and its climatic conditions instead of simply continuing to imitate the European model. As I say, it is similar to what happens with the mobile phone industry and, specifically, with an Apple with which all Chinese brands are compared at any given time. When Apple presents a new feature for the iPhone, we begin to see a rapid adaptation of Chinese mobile phones to include those features, while adding some new functions. The iPhone dynamic island and his twin in other brandsvisual elements in the operating system or the photo button (which existed long before Apple integrated it, but the influence of the apple brand is what it is) are three examples. For Bettane, the possibilities that China’s vast territory offers when it comes to creating and perfecting grape varieties are “unlimited.” And if you read me from France or are a lover of La Mancha wine and right now your fist is clenched… at least we have the cheese left. That, at the moment, has no Asian rival. Images | WBC, Treaty Port In Xataka | If the question is what is the future of wine, more and more Bordeaux wineries are clear about it: non-alcoholic wine

Shahed drones were a piece of cake for Ukraine’s helicopters. Russia has just transformed them into its biggest nightmare

by

In it huge catalog of innovations improvised measures brought by the war in ukrainefew are as revealing as the decision that Russia has taken to address one of the main vulnerabilities of its drones. In essence, they have turned the Shahed-136 (symbol of its saturation strategy through cheap and disposable platforms) in a rudimentary anti-aircraft fighter. The mutation. What was born as a suicide drone with autonomy to travel hundreds of kilometers following pre-programmed routes has been transformed, in some variants, into a system piloted in real timeequipped with cameras, modems and now with the R-60 missilea veteran infrared-guided missile from the 1970s that, despite its compact size, retains the lethality of a weapon capable of cutting a helicopter in two with its load of continuous rods. The broadcast images by Ukrainian organizations and electronic warfare experts confirm the presence of the R-60 mounted on the Shahed’s noseand the interception of one of them by a Ukrainian Sting drone illustrates that Russia is experimenting with the idea of ​​​​transforming a disposable projectile in a reactive vectorcapable of confronting the devices that, until now, acted as unpunished hunters of these platforms. The new tactical ecosystem. The success of the Ukrainian helicopters in intercepting Shaheds (with devices sporting dozens of shoot-down marks and crews accredited with hundreds of downed drones) had turned these aircraft in key pieces of low-level air defense. The combination of moderate speed, predictable trajectory and total lack of situational awareness made the drone a almost static whitevulnerable to cannon blasts or volleys used at close range. But the introduction of the R-60 upsets that balance: although the platform remains clumsy, slow and limited in maneuver, the simple fact that some drones can carry missiles will force Ukrainian pilots to rethink their proximity to the target. Each interception stops being a procedure and becomes in an unknown about what version of the enemy they will encounter. Extra ball. Even if the actual kill capability of the armed Shahed is small (and the operational window for targeting with a short-range missile is narrow) the statistical nature of swarm warfare change the calculation: In thousands of launches, just getting into a good position will be enough to cause the loss of a valuable helicopter. Technical limitations. The R-60, known by NATO as Aphidwas designed for supersonic fighters, not slow drones intended as loitering munitions. Its integration into the Shahed poses obvious challenges: the operator must manually retarget the drone until it is pointed at the target, achieving an adequate angle to allow the infrared seeker to acquire the thermal signature and maintain alignment long enough to authorize the shot. He narrow field of vision of the missile, the Shahed’s low maneuverability and the possibility of helicopters using infrared flares reduce the chances of success. However, historical experience shows that even imperfect weaponry can achieve victories if the tactical environment favors it. Remains of an intercepted Shahed with the R-60 attached The precedent. If we go back we have the Predator armed american with Stingers in 2002 (failed but deterrent), which reveals that these configurations do not seek air superiority, but rather force the enemy to act with caution. Just as Ukrainian unmanned ships were armed with missiles To scare away the Russian helicopters that were harassing them, Russia adopts the same defensive-offensive logic: a single one of these armed drones, hidden among a swarm of externally identical devices, forces the adversary to increase distance, use more expensive means or modify its interception doctrine. Drones against drones. The Shahed armed with an R-60 is not, by itself, a transformative weapon. It is, however, as symptom of evolution continued unmanned combat. Russia has expanded the Shahed family into versions with real time controljet variants already produced in its own factories and possible improvements based on artificial intelligence for dynamic target identification. Ukraine, for its part, develops interceptors low-cost that allow us to shoot down Russian drones without risking manned aircraft or spending expensive missiles. Every innovation generates a countermeasure: if Ukraine popularizes cheap hunting drones, Russia studies equipping the Shaheds of tiny turrets or new sensors, and if these become reactive, Ukraine adapts its doctrines and strengthens its electronic warfare. The conflict has entered a phase where the value is not in the perfection of each platform, but in the ability to produceadapt and deploy thousands of them in an environment where the line between offensive and defensive becomes blurred. The most dangerous sky. It is the result of these advances. The introduction of Shahed-R-60 marks a turning point because it erodes one of the few stable advantages that Ukraine had maintained: the capacity of its helicopters to hunt drones with relative safety. Now each aircraft must consider the possibility, however remote, of facing a missile that was not foreseen in the original mission design. This not only complicates interceptions, but forces disperse risks and rethink routes, altitudes and speeds. The Ukrainian sky, already saturated with suicide drones, cruise missiles, loitering munitions and manned aircraft operating in densely contested airspace, add another variable to an operational equation in constant mutation. And it is likely that this is just the beginning: the integration of missiles is a first step towards drones that, in addition to attacking by saturation, can defend themselves or even escort other devices in combined waves.

Einstein is the biggest rock star of the 20th century

by

Every now and then a news story is published where this or that scientist claims to have achieved something surprising: deny or confirm a theory put forward by Albert Einstein more than a hundred years ago. The unusual interest that the physicist arouses today is only the result of a process that already occurred while he was still alive: his status as a “star”, his status as celebrity. How is it possible that a theoretical physicist has achieved such fame and recognition? At Xataka we believe we have the answer: remove Adele and Taylor Swift because, behind Einstein’s casual hair, hides the biggest pop-rock star of the 20th century. Einstein’s story has everything to succeed, a story that could be called “the gravitational physics equation that made Spielberg cry”: that of a young Jewish man, shy, somewhat clumsy and with speech problems who fails his exams and, as he finishes his degree, cannot find a job. in yourshas to get to work in a gray patent office. That young man will take three years to revolutionize the world of physics and, by extension, the world in general. The tours Einstein spent much of the 1920s and 1930s on tour. Precisely, he was outside Germany when the Nazis took power and that, taking into account the desire they had for himsurely saved his life. He visited many places and there are hilarious anecdotes. Of course he was also in Spain. And the media and society at the time went a little crazy. Julio Camba wrote in El Sol that “the public that filled the classroom of the Faculty of Sciences. Mr. Einstein was welcomed with a great round of applause. Undoubtedly, all of us gathered there admired him a lot; but if someone asks us why we admired him, they will put us in quite a serious situation.” Cartoons like this image of Bagaria that we attach below filled the front pages of the newspapers in Madrid, Zaragoza and Barcelona. After all, he was already a Nobel Prize winner (the diamond disk of science). Thanks to that it became popular even among the popular classes, such as says historian Thomas Glickwalking down the street, a chestnut seller recognized him on the street and shouted to him “Long live the inventor of the automobile!“How long live it!” The groupies and the haters There is no rock star without groupies. That’s how it is. Fans sneaking into the singer’s house to steal a souvenir are a classic in the world of music. It also happened to Einstein. In late May or early June 1978, Michel Aron (newly named editor of New Jersey Monthly) approached a 27-year-old editor named Steven Levy and said, “I want you to find Einstein’s brain.” Rumors had been circulating for years about the brain in question. Steven Levy scoured the entire United States to find the coroner who performed the physicist’s autopsy. When he found Thomas S. Harvey He confessed that he had stolen the organ without the family’s permission and had been taking it around the United States for more than 30 years. Undoubtedly, Einstein also took the fan phenomenon to another level. Einstein some strong smear campaigns. It is logical, taking into account that among his detractors were some of the greatest experts on haterism in history. “100 scientists against Einstein“was perhaps the most aggressive campaign. But he resolved it with a phrase: “One hundred? Why so many? If I were wrong, only one would be enough…”. For the rest, the truth is that it must be recognized that he quickly became an endearing, distracted and somewhat crazy being. Einstein for a while They say that at a social gathering, Marilyn Monroe crossed paths with Albert Einstein, they started talking and, at some point, she said to him: “Professor, we should get married and have a child together. Can you imagine a baby with my beauty and intelligence?” Einstein very seriously responded: “Unfortunately I fear that the experiment will go the other way and we will end up with a son with my beauty and intelligence.” The anecdote, which is almost certainly lieshows the social and cultural stature of that Jew from Ulm called Albert Einstein. A carving that has generated countless cultural products. Some tremendously good. Become a symbol of peace, creativity and the use of science to help humanity, any excuse is good to celebrate it publicly. For our part, we just need to finish with what is perhaps the most important quote that Einstein said in his life. “Rest and be relatively good.” In Xataka | Einstein’s first violin had passed unnoticed.

OpenAI’s biggest fear is not that the bubble will burst. It’s just that I do it ahead of time

by

Sam Altman has admitted in an internal memo published by The Information that Google is catching up technologically with Gemini 3. That’s a real problem for OpenAI, but OpenAI’s real concern isn’t that. It’s just that he needs the party to last long enough to give him time to build his own infrastructure. Why is it important. OpenAI plans to burn more than $100 billion in the coming years pursuing AGI. But it is completely dependent on Microsoft for servers, NVIDIA for chips, and external investors for financing. Google, on the other hand, already has its own TPUs and generates 70 billion in free cash flow per year thanks to Search, YouTube and Google Cloud. If the music stops early, one survives and the other doesn’t. The paradox of timing. OpenAI faces a very peculiar race against time: If investment in AI slows in 2026 or 2027, it will have spent tens of billions but will not have completed its own infrastructure. You will remain tied to expensive suppliers. You will not be able to compete on costs with Google. Staying halfway is the worst possible scenario. Instead, if the bubble lasts until 2030 or beyond, OpenAI will probably have reached the threshold of self-sufficiency. It will have its own chips, its own data centers, economies of scale. It will be able to survive even when the investment tap is turned off. It’s like building a bridge: it doesn’t matter how much you’ve spent a lot. If you only get halfway, it’s of no use. The absence of moat. OpenAI cannot protect itself with sustainable technological advantage. In AI there are no defensive moats (moats) real. Every time OpenAI or any other lab makes a breakthrough, the rest replicate it within months. The only sustainable advantage OpenAI has left is cost. If you control your infrastructure, you can offer prices that no one else can match. If you do not control it, you become a dispensable intermediary between the end customer and whoever does have the chips and servers. The context of the memo. The document published by The Information reveals that Altman anticipated turbulence after the launch of Gemini 3. Google’s new model stands out precisely in the areas that generate the most revenue for OpenAI: automation of web design and programming. Altman acknowledged to his team that “Google has been doing an excellent job lately” and warned that he expects “the environment to be tough for a while.” But he urged them to stay focused on “achieving superintelligence”, admitting this would mean being left “temporarily behind in the current regime”. The figures. OpenAI went from almost non-existent revenue in 2022 to projecting 13 billion this year. It is one of the fastest business growth in history. But it plans to earn 200 billion in 2030. To achieve this, it will need to multiply its current income by 13 in less than five years. Meanwhile, it plans to spend $90 billion on R&D alone through 2030. That represents 45% of its projected revenue. Large technology companies allocate between 15% and 30% of their gross profit to research, not their total income. If OpenAI falls short of its billing goal, that percentage will be even higher. Yes, but. Google has structural advantages that are difficult to overcome: Generates a huge cash flow thanks to consolidated and very profitable products. You can afford to burn money on AI for years without too much trouble. And it already has its own infrastructure after a decade developing TPUs. OpenAI, on the other hand, lives off external funding. His recent agreement with Oracle to design data center components in the United States is an attempt to build that self-sufficiency. Altman presented it as “a step to ensure that the core technologies of the AI ​​era are built here.” At stake. OpenAI’s technological advantage over rivals such as Google and Anthropic has narrowed. Investors have sunk more than $60 billion into OpenAI, recently valuing it at $500 billion, betting that it will continue to dominate the market for AI that creates content and reasons like humans. That bet falters. Anthropic, founded four years ago by former OpenAI employees, is skyrocketing its valuation and aiming to generate more revenue than its former home selling AI to developers and companies. Their models specialize in generating computer code. And ChatGPT is still far ahead of Gemini in usage and revenue, but the gap is narrowing. Between the lines. Altman concluded his memo by acknowledging the pressure: “It sucks that we have to do so many hard things at the same time: the best research lab, the best AI infrastructure company, and the best AI platform/product company. But it’s our destiny in life. And I wouldn’t trade positions with any other company.” The question is not whether OpenAI can technically compete with Google. It’s whether you can hold on financially long enough to stop depending on others.

The opening of Shein in Paris should have been a triumph. It has ended up causing the biggest slowdown for the Chinese giant in Europe

by

Days after Shein’s controversial arrival at the historic BHV Marais in Paris —an opening as massive as it is controversial—, the story takes a turn that no one in the Chinese company expected. France has decided to postpone the opening of the rest of the Shein stores scheduled for November and December, a slowdown that reveals the extent to which the physical commitment of the ultra-fast fashion giant is shaking the sector and French politics. In a nutshell. The SGM group, owner of BHV, announced that the planned openings in Dijon, Reims, Grenoble, Angers and Limoges are postponed indefinitely. The inaugurations were to start on November 18 and extend until the beginning of December, but according to BFMTVSGM prefers to postpone them “a few days or a few weeks.” Today, the only operational Shein store in the country is the one in Paris, open November 5. A postponement that accumulates reasons. The delay does not respond to a single factor: it is a cocktail of commercial problems, reputational crisis, political pressure and regulatory turbulence. First, the Paris store disappointed its own customers. As reported days later by Le Mondedespite the more than 50,000 visitors on the first day, the result was frustrating: no men’s clothing, no children’s fashion, no large sizes, nor the ultra-low prices usual on the web. Added to this was insufficient space to manage the influx. But the hardest blow, according to the French media, did not come from the clients, but from the brands that have decided to leave BHV after the arrival of Shein and due to accumulated non-payments. Dior, Chanel, Guerlain and Lancôme – four pillars of French perfumery – leave the department store, along with more than 20 fashion and home brands. The departure comes at the worst possible time: the Christmas campaign, the month in which BHV rebalances its accounts. Furthermore, the image crisis is amplified by the breakup between SGM and Galeries Lafayette. According to Fashion Networkthe French chain has ended its agreement with SGM to avoid any link with Shein, which implies that all these centers will be called BHV, not Galeries Lafayette. Expansion meets politics. Shein’s arrival has unleashed unprecedented municipal rejection. From Liberation have pointed out that several mayors – Dijon, Reims, Grenoble, Angers and Limoges – are explicitly opposed to the implementation. Specifically, in Grenoble, Mayor Éric Piolle even asked to suspend opening until all products were legally verified. And the straw that broke the camel’s back. As different media have describedthe French Government discovered child-like sex dolls, prohibited weapons and other illicit products on the platform. This activated a process of temporary suspension of the marketplace, exhaustive customs controls and a judicial procedure that is still open. “The postponement is temporary.” Frédéric Merlin, president of SGM, insisted: in an interview for BFMTV. In it, he explained that the group needs to adapt the offer, adjust the pricing policy, gain space in regional stores and work on “more personalized orders.” But, as Le Monde recallsits management simultaneously faces non-payments to suppliers and the largest brand flight that BHV has experienced in decades. For its part, Shein maintains a different discourse. According to Reutersthe company says the Paris store has been “a great success.” He accepts that he must adjust prices and improve the experience, but he assures that for now his priority is to optimize that first physical point before opening the following ones. However, it does not offer new dates. Meanwhile, the company will have to face a key event: a mandatory appearance at the National Assembly and a court hearing on November 26, the same day on which the Paris court must examine the request to suspend the platform. In parallel, as the French media highlightsthe European Union has agreed to advance the application of taxes on small imported packages to 2026 – an essential pillar of Shein’s logistics model –, further increasing the pressure. Downshifting. France has become the first European country to put a real brake on Shein’s physical expansion. The openings have been postponed “a few days or weeks,” but the context—investigations, protests, brand leaks and regulatory pressures—suggests that the pause could last longer than SGM and Shein would like to admit. The question now is whether Shein will manage to adapt to a market that demands transparency, legality and social commitments or if the Paris store will be remembered as the beginning of the biggest clash between ultra-fast fashion and a country that, for the first time, has decided to put a stop to its advance.
