NVIDIA and OpenAI’s relationship is disintegrating

by

We have to talk. It’s not you, it’s me. Our love broke. That’s just what seems to be happening between NVIDIA and OpenAI, who just four months ago were living an idyllic moment. The first announced a mammoth investment of 100,000 million dollars in the second and everything indicated that we could have before us a new great technological empire. It was the most ambitious marriage in the history of technology, but now that marriage is failing. a decade of love. It was August 2016 and everyone knew about NVIDIA but almost no one knew about OpenAI. Jensen Huang, CEO of NVIDIA, saw clearly that the company had potential, so gave Elon Musk a DGX-1 serverits first “desktop supercomputer” for AI. OpenAI was using more and more advanced NVIDIA GPUs to develop its work, and with the explosion of ChatGPT in 2022, OpenAI became one of the largest customers of NVIDIA GPUs, which in turn was buying shares of OpenAI. The quid pro quo began. August 2016. The idyll began. Jensen Huang handed a DGX-1 to the co-founder and still member of the board of directors of OpenAI at the time, Elon Musk. From where I said I say… In September 2025 NVIDIA announced a “strategic investment” of up to $100 billion in OpenAI. Was one more gigantic case of circular financing that apparently made these two companies stronger and the others weaker. For a few days there has been talk that this announcement is being blurred and the agreement according to The Wall Street Journal is frozen. There they indicate that according to Huang, said agreement was not binding and he privately criticized that OpenAI had a lack of discipline in its business strategy. …to where I say Diego. At a meeting with journalists in Taipei on Saturday Indian that NVIDIA will “absolutely be involved” in the new funding round that OpenAI is carrying out. In fact, he assured that “we will invest a large amount of money, probably the largest investment we have ever made,” but when asked that this investment would be over $100 billion, he said “No, no, nothing like that.” Furthermore, as shown in the video of the included tweet, he clarified that the investment “we never said we were going to invest $100 billion in a single round” and highlighted that “there was never a commitment.” “We were invited to invest up to $100 billion and we were honored,” he explained, but added that “we will consider each round of financing separately.” narrative clash. Huang’s statements made Sam Altman quickly want to downplay the matter saying that “we expect to be a gigantic customer (of NVIDIA) for a very long time” and adding that “I don’t know where all this madness is coming from.” However, the statements of both parties suggest that there are differences of opinion and a latent tension in that hypothetical commitment that they had reached and that perhaps was not communicated or clarified adequately in September. OpenAI has its own NVIDIA complaints. In Reuters they point out that OpenAI is “dissatisfied” with some of NVIDIA’s AI chips because while they are great for model training tasks—preparing them before we use them—they are not so great for inference. OpenAI is said to be looking for alternatives to inference chips and is in talks with Cerebras and Groq to provide them with advanced inference chips. Here’s a bonus chapter: NVIDIA reached an agreement with Groq to license (“pseudo-acquire”) the company’s technology for $20 billion, which has blocked OpenAI’s talks with Groq. And look for other girlfriends. Sam Altman doesn’t hesitate when it comes to looking for alternatives to prosper. He did it when the relationship broke down with Microsoft and He looked for other girlfriends like SoftBankOracle or NVIDIA itself. But in reality he plays several sides, because he has become a shareholder in AMD, one of NVIDIA’s biggest rivals. But there is more. A lot more. Polyamory. Not to mention that Amazon is in talks with Sam Atlman to close an investment of up to 50 billion dollars on OpenAI. Or that Altman is also in negotiations with Softbank that could result in a investment of 30,000 million additional payments by the Japanese company, which had already promised a investment of 40,000 million of dollars a year ago. The amounts are dizzying, but OpenAI handles them as if nothing had happened. Dependencies and reverse lock-in. Typically, companies fear being locked into dependence on a vendor like NVIDIA. Here NVIDIA seems to be suffering just the opposite: being trapped by a client (OpenAI). If NVIDIA invests 100 billion, it becomes too dependent on the success of OpenAI. If Altman’s company fails or changes course, the hole in NVIDIA’s balance sheet would be catastrophic. It is “mutual assured destruction.” Image | Hillel Steinberg | Village Global In Xataka | The leaks are shaping OpenAI’s physical device: headphones that sit behind the ears

Ozempic came to simplify the relationship with food. Christmas is proving how wrong we were

by

Christmas has always been a delicate territory for the relationship with food. Family reunions, full tables and seemingly harmless comments turn these dates into a kind of silent examination of the body. For years the answer was the express diet before the holidays. Today, in many cases, the conversation revolves around a weekly injection. In the United States, there were cases of people skipping their Ozempic shot to enjoy Thanksgiving, according to The Wall Street Journal. The phenomenon in Spain is less visible, but the question is inevitable: what will happen this Christmas and what consequences could this jump have? Ozempic in Spain: a discreet use on the rise. Ozempic or other drugs based on semaglutide or tirzepatide have restricted access, require a prescription and, in theory, priority for patients with diabetes. Even so, its use for weight loss exists and is increasing, especially in the private sector. “In consultation, doubts begin to appear about what to do with these drugs on special dates such as Christmas,” explains Dr. Víctor Bravoendocrinologist interviewed in Xataka. “It is not always verbalized as ‘I’m going to skip the dose’, but the idea of ​​’stopping a little’, ‘adjusting’ or ‘I’ll see after the holidays’ does appear.” The difference with the United States is one of degree, not nature. There the debate It is public and massive. Here it begins more quietly, but with the same roots: fear of losing control, social pressure and a complex relationship with food that the holidays intensify. Understand well what it is. Ozempic is neither a one-time appetite suppressant nor a cosmetic aid. Its active ingredient is semaglutide, a drug that replicates the action of the hormone GLP-1 that the body releases after meals. This hormone intervenes in the regulation of insulin and satiety signals, so the treatment reduces appetite and prolongs the feeling of being full. “This is important to understand well,” emphasizes Laura Albó, psychologist specialized in eating disorders and EMDR traumawith whom we have chatted in Xataka. “It is not a pill that takes away the desire to eat only that day. It is a treatment that modifies the signaling of hunger and satiety on a continuous basis. Interrupting it is not neutral.” Besides, as recalled by the scientific reviews recently analyzed by the WHOthese drugs work to lose weight, but they are not free of side effects nor is their long-term impact still known with certainty. Nausea, digestive discomfort and, in some cases, abandonment of treatment are part of the real picture. The Christmas dilemma: enjoy without losing control. One of the most repeated promises of GLP-1 is peace of mind: eating without fear of overflowing. Precisely for this reason, Christmas is experienced as a paradox. “What we observed is that many people consider these dates as an exception,” explains Albó. “It’s the same mental scheme of diets as always: now I can relax, now it’s time to enjoy, and then I’ll control myself again. The tool changes, but not the logic.” According to the psychologist, the conflict is not so much in the amount of food as in the meaning attributed to it. “When someone feels like they need to skip treatment to enjoy themselves, they are reinforcing the idea that eating with pleasure and eating with control are incompatible. And that dichotomy is a clear basis for eating discomfort.” From a medical point of view, Dr. Bravo agrees that expectations are often unrealistic. “Some people hope that by stopping the medication for a few days the body will function as before the treatment. But what usually returns is not a ‘normal’ relationship with food, but a sharp increase in hunger and constant worry about eating.” As we have previously mentioned, in the United States, some patients delayed the weekly dose to arrive with a greater appetite for holiday meals. But Laura Albó warns that this approach displaces the problem: “It’s not just physical hunger. It’s mental noise, paying attention to the menu, the dessert, how much is left. Just what many people had managed to silence.” What happens if you skip Ozempic? From a physiological point of view, interrupting or delaying a dose can cause a return of hunger that is more intense than expected. “The body once again receives signals that had been dampened for weeks or months,” says the endocrinologist. “This does not mean that the person eats ‘normal’, but rather that they may experience a sharp increase in appetite and greater difficulty in self-regulation.” But the impact is not just physical. “On an emotional level, the effect is usually a swing,” adds Laura Albó. “First the idea of ​​permission appears—now I can eat—and then, if the person feels that it has gone too far, guilt and shame come. This cycle is well known in consultations.” Scientific evidence supports this risk. Studies on hormonal regulation of appetite show that the body’s adaptations after weight loss do not disappear immediately. Skipping treatment does not eliminate that vulnerability; in some cases it intensifies it. So what do the experts recommend? There is no single answer, but there is clear consensus among the professionals consulted: Do not make impulsive or guilt-based decisions. Do not use medication as punishment or as permission to eat. Maintain basic schedules and routines to avoid arriving extremely hungry. Understand that two or three meals do not determine the success or failure of a treatment. “The important thing is not to turn Christmas into a test,” summarizes psychologist Laura Albó. “Two meals do not change a body, but they can greatly alter the emotional state.” For its part, Dr. Victor Bravo He insists that any adjustment should be discussed with the professional who prescribes the treatment: “Not so much because of the specific meal of a day, but because of what that decision can trigger later.” The role of the family: the noise that cannot be seen. Although the focus is usually on who takes the drug, the environment has a decisive weight. Comments such as “how little you … Read more

After a love-hate relationship with cinemas that has lasted for years, Netflix has finally decided what it wants them for

by

Netflix finally seems to have assumed what its relationship with cinemas is: using theaters as promotion and as a way to create community with specific and very striking releases, which includes the theatrical release of the sumptuous ‘Frankenstein’ from Guillermo del Toro to the latest and highly anticipated episodes of ‘Stranger Things’. But although now there is complete calm, this relationship has gone through notable ups and downs: from the initial devotion and wanting to become a major of Hollywood to confront the old guard head-on, reaching this current middle ground that benefits both cinemas and the platform. Many moves. For more than a decade, Netflix has radically transformed the audiovisual industryfirst revolutionizing the home consumption model and then challenging traditional film distribution and exhibition systems. Currently, Netflix is ​​a giant available in more than 190 countries, with its own production that competes directly with the majors from Hollywood. And until reaching that point, Netflix has gone through very diverse stages: it tried to position itself as a conventional super-producer, there were controversies, triumphs at the Oscars, a certain cold phase of disagreement and, finally, a more pragmatic adoption of the theatrical space. Devotion and confrontation. In its first years of original production, Netflix wanted to play an important role within the conventional film industry. One of its first early milestones was the 2015 release of the film ‘Beasts of No Nation‘, both in selected rooms and on the platform itself. streaming. A bold move, since it involved challenging the traditional model of release windows that until then gave up an exclusive period of time in theaters before reaching other formats: Traditionally, this window could last between 90 and 180 days. The conflict begins. The powerful North American cinema chains and the most prestigious festivals began to openly reject Netflix moviessince they considered that the absence of a long theatrical window affected the overall profitability of the releases, and would end up damaging the theatrical experience. This situation led to public tensions given that Netflix excluded from some major film festivals for several years. Netflix he defended himself saying that their model prioritized the viewer’s experience at home and that they understood the theaters as a complement and not the core of their business. At the same time, it was generating more and more original production, of increasingly higher quality and budget. And COVID arrived. Netflix’s position backed by traveling companions like HBO (paradoxically, property of a majorWarner, which was beginning to see a clearer benefit in the streaming that in the rooms) had as its fruit a crisis of the film distribution model. The situation became particularly acute during the COVID-19 pandemic, which accelerated the decline in viewers, completely settled the streaming experience and gave rise to decisions that were, in a certain sense, the final straw for classic distribution: majors traditional companies such as Disney and Warner releasing blockbusters of the caliber of ‘Mulan’, ‘Black Widow’ or ‘Kong vs. Godzilla’ at the same time on their newborn platforms. streaming and the cinemas. Have a mania Significantly, in May of this same yearTed Sarandos, executive director of the platform, criticized the theatrical experience, which he defined as “outdated” and “restricted.” He stated that the long-running theatrical window, traditionally defended by cinema chains, is not compatible with their business model. And although Netflix recognizes the cultural value of theatrical cinema, for many of its releases, “streaming first” is what drives success and the construction of fandoms. Already then he stated that each film has a “tailored” strategy regarding its relationship with theaters, and that is what we are seeing now. Of course, without passing up the opportunity to say that Netflix is ​​not destroying Hollywood, but “saving” it. Change of strategy. In recent years, Netflix has begun to show an evolution in its strategy regarding movie theaters, adopting a more pragmatic approach. One of the milestones that mark this change, and which was already mentioned in the aforementioned interview with Sarandos, is the decision to make outstanding theatrical premieres for productions with a high potential for cultural and popular impact. Significant example: the premiere of the final season of “Stranger Things” in select theaters, a move that combines the platform’s drawing power with the community and promotional effect of the theatrical experience. Netflix knows well that the theaters are remnants of the past, but they still have an indisputable communal power of attraction: there are films that appeal to specific audiences and very juicy areas of the fandom, as was the case with ‘The K-pop Warriors’. This film was a milestone: the first Netflix title to reach number one at the US box office, which makes clear the company’s ability to use theaters not only as a traditional distribution channel, but as a space to amplify platform phenomena. Hybrid model. Netflix’s current strategy is a hybrid model: it combines the strength of streaming with the cultural and promotional value of the cinema experience. Instead of seeing the rooms as a distribution channel, Netflix uses them as a speaker. Not as competition, but as strategic promotion allies. It is clear that Netflix has discovered what it can get out of traditional exhibition: Now it remains to be seen if the theaters understand what they can get out of a hypothetical (and much-needed) symbiotic relationship.

Marcos Llorente has an eccentric and disturbing relationship with light. And science has things to say about it.

by

Marcos Llorente is news. Again. And not because of football or anything remotely related to sports. It is because a video of almost four minutes recorded (and published) by the RFEF during the Red concentration in which the man from Madrid reveals some of his “healthy” habits, practices that include the use of red lights inside the house or glasses with yellow lenses to filter blue light. Opinions that highlight its eccentric appearance and raise the eyebrows of the experts. What has happened? That Marcos Llorente has become news beyond the sports pages. And he has done it on account of a video published by the RFEF in which he does not talk about techniques, his play on the field or how he sees the National Team facing the next World Cup. No. What he’s talking about is his personal health routines. More specifically those related to light and sight. What exactly did he say? First of all, at home you only use certain lights. “During the day I don’t turn on the light because either I’m always in the garden or, if I go into the kitchen or living room for anything, light comes in through the windows,” explains in the video under intense reddish lighting. “When the sun goes down, this is the light I have throughout the house. What this lamp does is bring that red and infrared into the room and makes it more similar to the light outside.” Click on the image to go to the tweet. Is there more? Yes. The man from Madrid elaborates on an accessory that has been seen on him on other occasions and it has also caused people to talk: the yellow lens glasses. “They are for when you are, during the day, indoors. Outside you should never wear glasses of any kind. They should always give you the sun’s rays in your eyes and skin, without anything interfering. And red glasses, with the red lens, what they do is filter all that blue light that lamps and televisions or telephones have.” And why all that? For health. Or at least that is what the footballer maintains, who defends that what he does transcends his role as a footballer. “I feel very good. All these things I do are for health, not for football. What happens is that in the end one thing is linked to the other. I think that when I leave football I will continue with this and surely I can do it more perfect,” concludes the man from Madridwho during the video shares other of his habits, such as going outside before dawn or starting the day with coffee and “two or three tablespoons” of butter. What do the experts say? Whatever Marcos Llorente says, the effectiveness of the filters is debatable to say the least. In an article Published a few years ago, the Spanish Society of Ophthalmology already insisted that “blue light from screens does not affect the eyes or cause blindness.” The report was actually launched after a study “of dubious scientific origin” created alarm with “unfounded conclusions” about the supposed impact that this light can have on eyesight. “Although blue light is often associated with computers and phones, the largest source of blue light is sunlight. Exposure to blue light from screens is much less than the amount of blue light we are exposed to from the sun. Additionally, it is no more harmful than sunlight,” comment Dr. Rahul Kurana, spokesperson for the American Academy of Ophthalmology. Do the lenses work? Ophthalmologist Sara E. Hernández is blunt in statements collected by The Vanguard: “There is little or no effect of lenses or glasses with a yellow filter on visual performance, measured in terms of best corrected visual acuity, compared to lenses without a blue light filter.” There are studies, such as It is published in 2013 in Journal of Human Kineticswho after carrying out tests with colored lenses found that there are no “significant differences” in issues such as visual acuity or depth perception. Where does this come from? Concerns about blue light and the benefits of filters are not new, as remember the Spanish Society of Ophthalmology itself, and have been expanding as the use of screens and LED lights spread. They have spoken on the subject users, academics and collegiateincluding the American Academy of Ophthalmology, which in 2017 published an article written by Celia Vilmont and reviewed by Dr. Khurana that begins with a blunt statement: “There is no scientific evidence that blue light from digital devices can cause damage to the eyes.” Now Marcos Llorente becomes the new greatest exponent of these theories, despite the paucity of evidence scientific. Is it something new? More or less. The RFEF video is new, but it is not the first time that Llorente has made headlines for his opinions on topics that have nothing to do with football. In his day it was for the use of glasses and now it is also for his statements about the chemtrails. His words achieve notoriety for several reasons. The first, his status as a footballer. The second, the speaker that you have beyond your personal networks, such as the official account of the National Team or media in which share his extra-sports comments.

We increasingly understand the relationship between intestinal flora and sleep quality

by

Many researchers ago They have been pointing That the intestine is not limited only to digesting food. It has neurons, produces substances that the brain also uses to communicate and, most curious, seems to be in direct contact with it. Hence some call it “The second brain”And maybe it does not sound so exaggerated if we think it can also influence how we sleep. Sleep badly affects digestion (And vice versa). It happens to many: after a heavy dinner it costs to sleep, and after a bad night the stomach seems more sensitive. Even if they seem like unrelated, they are actually connected. When one of the two fails, the other also shows it. Sleeping badly stresses the body, more cortisol is released and that can alter the functioning of the intestine. And if the digestive system does not do well, send signals to the brain that complicate relax and reconcile sleep. It is like a silent talk that happens all the time between what happens in the head and what it feels in the belly. The scientific support. There are more and more research that confirms something key: the quality of sleep is closely linked to the state of our intestinal microbiota. One of the most interesting studies was published in 2023. The scientists used a fairly accurate technique – called “bidirectional Mendelian random” – and showed that the dream and the intestine are in constant communication. When that balance is broken, either by a bad rest or by a digestive mismatch, both systems are affected. In addition, the most curious thing is that the key hormone to regulate sleep occurs in the intestine: melatonin. According to an investigationhaving an intestine in equilibrium could be one of the keys, sometimes invisible, to be able to sleep well. But … And stress? Stress is another great actor in this story. When you are stressed, not only costs you more to sleep. The digestive system is also altered. And most interesting: the intestinal microbiota is also affected. In fact, a recent study He has found That the intestine reacts to stress and, dependent on how it is, can calm or worsen it. If the intestinal flora is unbalanced, more anxiety, more irritability will be felt, and will cost more relax. In the end, it is a vicious circle: stress alters the intestine, the intestine responds badly, and all that interferes in sleep. The focus on food. The diet is key to maintaining a balanced microbiota, which helps regulate sleep and mood. A study He has revealed The importance of eating with regular schedules, avoiding heavy or late dinners, incorporating fiber -rich foods, natural fermented ones such as yogurt or kefir, and reducing outraprocesses can have a real impact on your rest. I even know has observed That certain probiotics, such as Bifidobacterium brief, can improve sleep quality by influencing the hormonal axis that regulates stress. Sleeping is not a matter of a good pillow. That too. Sleeping well is an act of balance. Not only mental, also intestinal. Understanding that invisible connection between the brain and the digestive system can be the first step to recover rest. Because sometimes, taking care of the belly is also taking care of sleep.

We have discovered a relationship between olive oil and risk of death by dementia, a point in favor of the Mediterranean diet

by

Someone could think that everything is already said, all investigated, on one of the fundamental axes of the Mediterranean diet, olive oil. Nothing is further from reality: research on this food continues and continues to reveal striking aspects of the liquid. And as regards striking relationships, perhaps the palm is taken by the fact that they keep the consumption of this derivative of the olive and dementia. 28%. A study published a few months ago established existence of this relationship. Specifically, the analysis responsible for the analysis observed a 28% reduction in the risk of death associated with dementia between people who consumed at least Seven grams of olive oil per day, compared to those who did not consume this liquid or did it rarely. Until now, some studies They had indicated us an inverse relationship between the Mediterranean diet and the cognitive deterioration associated with age. From there, establishing relationships between different aspects of these variables can help us better understand the link between Mediterranean diet and healthier aging. Changing ingredients. In its analysis, the team also studied the effects of replacing different sources of fat. Through a substitution modeling, they estimated that replacing five grams of margarine or mayonnaise daily with an equivalent amount of olive oil could be related to a decrease in the risk of mortality associated with the dementia of between 8% and 14%. A similar analysis did not detect similar effects when these fats were replaced by other vegetable oils or butter. 92,383 participants. The study was conducted from the macro -conformation Nurses’ Health Study II and Health Professionals Follow-Upwhich allowed to obtain Information about 92,383 participants. These filled surveys on eating habits every four years over a 28 -year period. The team divided these participants depending on their olive oil consumption: those who never consumed olive oil or did it less than once a month; who consumed up to 1.5 grams per day, who consumed between 4.6 and 7 grams per day; and a group for those who consumed more. The team extended its analysis over 18 years of the study and controlled aspects such as the general quality of the diet or the genetic predisposition to suffer from the disease. The details of the study were published In an article In the magazine Jama Network Open. What is happening? When establishing a causal relationship, it is always convenient to understand what mechanisms are operating behind this relationship between olive oil consumption and death risk associated with dementia. “Olive oil is rich in monounsaturated fats and contains components with antioxidant activity that can play a protective role for the brain,” He explained to the environment UPI Anne-Julie Tessier, co-author of the study.

We have been detecting a relationship between Herpes and Alzheimer’s years. Now we are discovering that treating one helps with the other

by

A few years ago the scientists detected A strange coincidencea relationship between herpes virus and a neurodegenerative and noncommissible disease: Alzheimer’s. What at the time seemed a spurious and casual relationship, it seems more and more proven and proven. Adding tests. Now a new study He has obtained evidence of this relationship. However, perhaps the most important fact that we can extract from the new analysis has to do with vaccines against infection. According to the study, antiviral treatments against herpes are related to a 17% lower risk of suffering from Alzheimer’s, suggesting that treatment against this virus can protect us against the appearance of this form of dementia. HSV-1. In study he linked again the infection by the Herpes simplex virus Type 1 (HSV-1) with the appearance of Alzheimer’s disease, a form of dementia that is characterized by accumulation in the brain of beta-amyloid plates. Today we do not have a clear idea of ​​how this relationship occurs “(Some) studies have indicated that inflammatory alterations in the brain caused by HSV infection are central to the development of (the disease),” Explain the team Resposable study. “It is pointed out that peptides (beta-amyloids (Aβ)) are deposited in response to HSV infection and protect host cells (…). Consistently, they threw antimicrobial properties against several pathogens, including HSV-1,” they detail. 344,628 matches. In his study, the team He turned to 344,628 participants with Alzheimer who were paired with two participants without diagnosis but with similar characteristics. They observed that among people with Alzheimer’s 0.44% had been previously diagnosed with HSV-1, while only 0.25% of the control group had the same previous diagnosis. The analysis indicates that, taking into account other relevant factors, the probability of finding a previous HSV-1 diagnosis was 80% higher among people with Alzheimer’s than in people without the disease. The details of the study were published In an article In the magazine BMJ Open. Not only HSV-1. The study focused on a variant of the herpes virus but also paid attention to other pathogens of the “family”, such as the HSV-2, Varicela Zoster, or Citomegalovirus. They found a relationship between two of them (HSV-2 and Vicela Zoster) and a greater risk of Alzheimer’s. Understanding the causes. New studies will still be necessary that Explain biochemical mechanisms that explain this type of relationship between infectious processes and noncommunicable diseases. Only in this way can we establish the underlying causal relationships and, hopefully, to find more effective treatments in the fight against disorders as serious as cancer and Alzheimer’s. “Although there is a lot of research ahead to find out the reasons and mechanisms that lead from infection to a process of dementia that manifests many years later, the accumulation of the evidence suggests that the management of these infections, with treatments that are effective for all herpes, or with vaccines such as herpes zoster, is an interesting tool to reduce the risk or delay dementia” explained to SMC María Jesús Bullido Gómez-Heres, head of the Research Group Pathogenic mechanisms of Alzheimer’s disease, who was not involved in the study. Not so non -transmissible diseases. This is not the only example of a noncommissible disease to which we have found a surprising relationship with past infections. A recent example We find it in colorectal cancer and its possible link with infections caused by bacteria Escherichia coli. In Xataka | We are getting closer to ahead of the arrival of Alzheimer’s.

Nvidia is tensing her relationship with the US government. His presence in China is at risk

by

For Nvidia losing the Chinese market is not an option. During the last fiscal year, which expired on January 26, 2025, China represented approximately 13% of total income of the company led by Jensen Huang with a figure of some 17,000 million dollars. In practice, the country governed by Xi Jinping is the third best client of this company only behind the US and Taiwan. However, the sanctions to China that are deploying the US government threatens Nvidia’s survival in this Asian country. Currently this company cannot sell its chips to its Chinese clients to artificial intelligence (IA) more advanced. And in the middle of last April the US Department of Commerce imposed new export restrictions on China from The H20 GPU of Nvidia. The tuning of a trimmed review of the H20 GPU is underway The reception they have given to the GPU H20 The Chinese clients of Nvidia has been very good despite the fact that the capabilities of this chip are clearly lower than those of the other proposals for the this company. In fact, initially the Department of Commerce allowed its sale in China because this integrated circuit met the restrictions it had imposed. And despite its limitations its sales in China 50% quarter to quarter have grown Since he arrived in this market in mid -2024. The Nvidia Plan requires a cut review of the H20 GPU that satisfies the restrictions imposed by the US Department of Commerce Anyway, this time of bonanza is over. The restrictions of the Department of Commerce in practice prevent Nvidia Deliver the H20 GPU to its Chinese clientsbut this company does not give up. At the beginning of this week We explain to you that several reliable media had collected that His engineers are working on new GPU for AI expressly adapted to the country’s market led by Xi Jinping. Now we know something else. And is that according to Reuters The Nvidia Plan requires tuning a trimmed review of the H20 GPU that satisfies the restrictions imposed by the US Department of Commerce. The surprising thing is that this project seeks to cut a chip that is already a cut version of other NVIDIA GPUs. And it is not clear that with this limited benefits this trimmed GPU H20 is interesting for companies that have bought the original H20 chip from NVIDIA. Among them are no less than three giants from China: Alibaba, Tencent and Bytedance. However, Nvidia faces one more challenge: Huawei’s competition. And this last company is reinforcing its position in China to take advantage of the hole that Nvidia is leaving in the market because of US sanctions. During the second half of 2025 will manufacture the GPU Ascend 920 on a large scalewhich is clearly destined to occupy in the Chinese market the gaps that the GPU H20 is going to leave. And, in addition, it is about to start the chip test phase Ascend 910dwho seeks to overcome the performance of the chip NVIDIA H100.

Chatgpt has been a tool. If you start remembering all our conversations, it will be something else: a relationship

by

A few days ago, Openai announced an “memory” update for chatgpt: You will begin to remember all our conversations Already take them into account when giving us an answer. No four inferred pieces as before: All our history. Well, it wasn’t even Openai who announced it. Was Sam Altman in Xas who does not want the thing. Openai focused those days on giving a court to a GPT 4.1 Much less transcendent for the user. And a few days later, Grok announced the same movement. The new super memory (not yet available to the European Union) is a total change in the use we give to Chatgpt. And to a lesser extent, to Grok, who does not have a lower professional utility. We are no longer facing a tool that we use and abandonbut before a digital entity with which we have an evolutionary conversation. A relationship. Let’s think about how we use a hammer, a calculator or even Google: we use them to solve a problem and then forget them until the next time we need them. There is no evolution in our interaction with them. On the other hand, our relationship with another person is contrasted on a cluster of previous interactions. We do not expect to have to remind a friend what team we are, or our partner what music we like. There is something deeply human in wanting to be rememberedto desire continuity in our interactions. The IAS that offer this experience will have an advantage not only technical and functional, but also psychological. Each conversation with chatgpt – at the margin of the utility of the GPTS– It will no longer be an eternal first day, but the continuation of a thread of shared knowledge. An assistant who remembers your allergy to nuts. Which understands that you like explanations with sports analogies. Who knows that you are working on an important personal project. On face B of the album, the concerns that it provokes to deposit so much about ourselves in an entity controlled by a company. Persistent memory offers extreme customization, but it also costs us A privacy toll. Openai says that you can deactivate this function, but the value of the service decreases if you do. It is a usual dilemma for any user of modern services. It will also exist for some The subtle temptation to replace human interactions – Sometimes frustrating – for more predictable interactions with an AI designed to please us. The AI ​​never tired, never has a bad day, never judges our repetitive questions or laughs if we ask something too basic. It is an idealized company version that could be too attractive to some, especially for those who feel alone. It is the first stone of A new type of software that asks for another type of relationship. And we are not accustomed to something like that. It is not useful to treat it as another human, but neither as the classic tools. Another conceptual category will need. Chatgpt will know us better than many of our friends and family. It will be something that maintains the thread of our thoughts throughout weeks, months and years. A constant presence that will evolve with us, which will even anticipate our desires. Chatgpt will no longer be a tool, but something much more intimate and personal. Almost alive.

There is a relationship between eating fruit, drinking coffee and the risk of tinnitus. But we still don’t understand where it comes from

The human body is a very complex machine in which millions of interactions are produced, some intuitive and direct, others that are neither one nor the other. This sometimes implies that we find correlated phenomena after which there could be causal relationships that we are not yet able to understand. An example of this in a curious connection that unites our digestive and auditory system. A new study. A Chinese researchers team He has studied The relationship between certain foods and the risk of suffering tinnitus. The team found that greater consumption of fruits, fiber, dairy and caffeine were linked to a lower risk of suffering from this annoying disorder. The ears. Tinnitus It is nothing but a technical term with which we refer to the sensation of buzzing or beep we perceive in the ear. A noise that only exists in our head and that can be presented in a diversity a wide range of shapes, each with different characteristics, some of them very annoying and difficult to treat. These forms They have diverse originssuch as age loss related to age, possible ear injuries, or circulatory system disorders. It can manifest intermittently or permanently, and it can also be intense enough to interfere with our audition or limit our ability to concentrate. Meta -analysis The notion that there is a link between some foods and the risk of suffering tinnitus It is not new. Various studies can be found that have previously investigated in the field but drawing conclusions from this literature is not easy. That is why the team responsible for the new work carried out a study of this scientific literature, a review of literature, from which it carried out a quantitative analysis of the results identified in this, that is, a meta -analysis. The team compiled and analyzed the results of eight studies which accumulated a total of 300,000 participants. They analyzed the effects of 15 dietary factors on the risk of appearance of this auditory disorder. Different foods, different impacts. The study estimated from these eight previous works that greater fruit consumption could be linked to a 35% reduction in reducing the risk of tinnitus. The reduction associated with greater dairy consumption was 17% and that of the caffeine of 10%. They also observed a 9% reduction in the probability associated with the highest food fiber consumption. The details of the study were published In an article In the magazine BMJ Open. Prevent yes, cure right? The results are striking, but the interpretation is complex. The reason is that We have no clue on the hypothetical cause and effect connections that could be behind this relationship. That is, we can observe correlation but we cannot infer causality. Another track on this connection is found in another review of the literature made a few years ago. Posted in 2020 In the magazine International Archives of athinolaryngologythe work also observed a link between caffeine and tinnitus but warned that it only occurred preventively: that is, it observed that caffeine consumption was linked to a lower risk of suffering from tinnitus but a greater consumption of the substance did not serve to improve the state of those who already suffered the problem.
