relationship

OpenAI wants its own Alexa, but on steroids. Its first device seeks to change the relationship with AI, according to Bloomberg

by

Home assistants have been operating for years around a simple logic: we give an order, the device executes a task and the relationship usually ends there. The bet that OpenAI would be working on aims precisely to break that limit and give artificial intelligence a more continuous role within the home. It wouldn’t just be about answering questions or activating services, but about learning from the user and offering help before they have to ask for it. The OpenAI device. According to BloombergOpenAI is working on a screenless home device, similar in general appearance to a speaker, but designed to be moved around the house thanks to a rechargeable battery. The company would like to make it the physical embodiment of ChatGPTcapable of responding to messages, playing content, controlling connected devices and helping with different tasks. It should be noted that the company has not presented it and there is no official information yet. Jony Ive, Apple’s former design chief, is also behind the project. OpenAI paid $6.5 billion in 2025 for io Productsthe company he had co-founded, while his studio LoveFrom participates in the design of this new family of devices. The team also brings together numerous former Apple designers and engineers responsible for products like the iPhone and Mac, a concentration of talent that helps understand both the ambition of the project and the legal conflict surrounding it. Your own Alexa, but with another ambition. The entry of the firm led by Sam Altman in the home it would put it in front of Amazon, Google and Apple, companies that have been building their own ecosystems of speakers, assistants and connected devices for years. According to the aforementioned medium, the difference would be in a more personalized and proactive experience, capable of learning from the user and offering information without always waiting for an order. OpenAI would describe it internally not as a simple smart speaker, but as a computer conceived from the beginning to work with artificial intelligence. The difference would be in its ability to interpret what is happening around it using a camera, several sensors and more advanced models than those available in conventional home assistants. Instead of processing an isolated instruction, the system could take into account the environment and the specific moment to determine what information is useful and how to respond. New voice model. Much of that experience would depend on GPT-Livea more advanced version of ChatGPT’s voice mode that OpenAI launched in July 2026. The idea is that you can listen and speak at the same time, adapting more naturally during conversations and processing information quickly. The device would also incorporate mechanical elements capable of moving on their own. With this, the company would try to reinforce the personality of the device and generate the feeling that “it is alive.” To anticipate, you will have to know us. OpenAI would like the device to become a kind of expert on its user over time, capable of identifying what information may be useful at any given moment. Bloomberg notes that to achieve this, it could turn to personal information, such as emails, and use it to better understand its owner. This personalization would be one of its main arguments, but it would also force us to decide to what extent we are willing to open our digital lives. Apple’s lawsuit. The project is also moving forward under pressure from a Apple lawsuitwhich accuses OpenAI of having used trade secrets to accelerate the development of its devices. OpenAI maintains that it knows of no evidence to support those accusations, although Apple has requested a court order that could delay its commercialization. According to Bloomberg, the company aims to present the product during 2026 and launch it in 2027, as long as the technical and legal process allows it. The final bet is to turn ChatGPT into a physical presence that we live with daily.

something is wrong with the relationship between the sea and the atmosphere

by

We are in the middle of June and it doesn’t seem like it, but the western Mediterranean is burning. And no, it is not an exaggeration: we are talking about a marine heat wave with peaks of surface anomaly greater than 5 degrees in specific areas. It is what experts call in technical jargon, a gigantic problem. Especially, facing autumn. A ticking time bomb. The great temptation when we see this type of data is to plot a direct line between sea temperature in June and DANAs in October. But it would be a mistake. The mechanism exists, of course. However, the matter is a little more complex than we might think. This is because the overheated sea is not a forecast of how much autumn rain we are going to suffer: it is a gauge of the ceiling of intensity that these rains can reach. The effect of an anomalously warm Mediterranean is to charge the atmosphere with water vapor and thus raise the amount of water that a DANA can precipitate. But, and this is crucial, the trigger is atmospheric. It is useless to have a charged atmosphere without a mass of cold air at altitude that is detached from the general circulation. What’s new? What is genuinely new is not that the Mediterranean is hot. It is, in fact, from 2022 on a sustained basis. What is new is that we have had a marine heat wave since May. That is, long before the historical calendar and still very far from the warmest moment (August). Furthermore, whether we want to see it or not, El Niño is just around the corner and, although we hope not to receive its wildest impacts, the heat it will bring to the world makes experts very worried. Why is it relevant? The data is clear. The Mediterranean basin heats up around 20% faster than the global ocean average and is trailing a streak of unprecedented records: 18 of the 20 highest daily values ​​since 1982 were recorded between 2023 and 2024 (with a maximum of 28.15 °C on August 10, 2024). The memory of the DANA of Valencia is still fresh and the certainty that the situation is getting worse It is a slab for the national climate conversation. Are we going to get worse? It’s pure physics: a warmer sea increases evaporation and the water vapor content of the atmosphere (at a rate of 7% more vapor for each degree). The best example is Storm Daniel which, as the researchers showedit would have been much more unlikely without climate change. That is why it is advisable to be precise and not take things out of context. The current scenario is problematic because if a DANA forms on the Mediterranean coast this autumn, it will have more fuel available to discharge more intense rains than with a cold sea. If it is not formed, nothing has to happen. Image | Copernicus In Xataka | We already know exactly how much climate change was to blame for DANA in Valencia (and the figures are devastating)

Samsung is NVIDIA’s best friend. AMD just got into the relationship and TSMC looks askance

by

Lisa Su has been at the head of AMD since 2014. Captaining such an important ship, it is assumed that on some occasion he will have visited one of its main component suppliers. But it turns out that, in his role as CEO, he had never traveled to South Korea, home to one of the world’s leading foundries. The journey has paid off and AMD turns with latest generation memory. But the one who is happiest is the one who is going to allow AMD and NVIDIA to create their new platforms for AI. Samsung. Visiting. In Pyeongtaek, south of Seoul, is one of the main factories from Samsung. The South Korean company is expanding and has the objective of becoming one of the names of the American industry while maintaining its local muscle, and the plant inaugurated a few years ago is an example. This is how Samsung makes money: the secret is in the IPHONE As it could not be otherwise in these times, the facility is focused on the creation of memory chips to power the AI ​​hardware. SK Hynix and Micron are the two big competitors of Samsung in this field and are also opening and purchasing plants to increase their memory production. And AMD wants a piece of that pie because Samsung is, right now, the main supplier of next-generation memory. The agreement. The trip, apart from seeing the facilities, was the perfect setting to make the announcement that Samsung was will convert in the main memory supplier HBM4 from AMD. Specifically, the Instinct MI455X GPU, the next generation of the American company. Because when we talk about GPUs for AI, we talk more about NVIDIA (which also they just presented news) because they are pulling with everything (and in all sectors), but AMD is the other big one that doesn’t want to be left out of the conversation. They are achieving billion-dollar agreements with companies like Metathey have some growth forecasts stratospheric and although far from NVIDIAthey want to be in charge of providing the hardware for AI. Happy managers | Photo: Samsung HBM4. That Samsung is the one that supplies the HBM4 memory to AMD is great news for them because they are the ones that, at least for the moment, have the most refined manufacturing process for this type of memory. In the past they had already supplied the HBM3E for AMD’s current MI350X and MI355 accelerators, but the new agreement means that they will access the same type of memory as their own Samsung exclusively supplies -for now- to NVIDIA. Memory is not everything, obviously, but it plays a fundamental role. The higher and faster bandwidth, the more data per second it can handle. Think of this memory as a very wide and perfectly paved highway. And Samsung was the only one that had managed pass demanding NVIDIA tests for your new architecture Vera Rubin. Samsung at its best. And in this agreement it is evident that both parties win, but Samsung is achieving extreme recognition in recent months. Achieving the agreement first with NVIDIA and now with AMD implies that they separate from their main rivalalso South Korean SK Hynix, which is somewhat further behind with the development of its HBM4 chips. But, furthermore, the release AMD indicates that Samsung will also supply DDR5 memory to AMD’s EPYC servers and the possibility of them manufacturing some of AMD’s future chips has been discussed. Because Samsung manufactures memory, yes, but also other processors. There they have their own Exynos for the Galaxy S26but in the past they manufactured the most powerful Qualcomm Snapdragons and it has been proposed again that the South Korean company be the one make 2 nanometer chips from Qualcomm. On the other hand, they have already won a contract of more than 16,000 million with Tesla to create chips focused on AI. It is clear that TSMC is the main foundry in the world, but Samsung is determined to be one of the main hammers with which to build the future of AI. And, speaking of the king of Rome, the agreement means that Samsung manages to take over TSMC and AMD achieves a second role to reduce its dependence on the Taiwanese company. because there We already know that there is a best friendand it is undoubtedly NVIDIA.

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.
