If you think that renovating your house is urgent, think about this building in Ukraine. Its hole is so big that it is a danger for Europe

by

He Chernobyl accident released so much radiation that some areas they remain uninhabitable almost four decades later. In fact, the plant continues to house materials capable of remaining dangerous for thousands of years. Therefore, keeping them under control is one of the greatest engineering challenges ever faced in Europe. A challenge that a drone has put to the test. It was to last a century. The story we tell it a few months ago. The gigantic steel arch built over Chernobyl reactor 4 was conceived as a definitive solution to contain the worst nuclear accident in history for at least a hundred years, a colossal structure designed to isolate the ancient “sarcophagus” and buy humanity time. More than 100 meters high and capable of housing entire monuments inside, this system had to resist extreme conditions and allow the safe decommissioning of the reactor, encapsulating hundreds of tons of radioactive material that remain active decades after the disaster. The impact that changed everything. But everything changed in February 2025when a drone attack in the middle of the night pierced that shell seemingly invulnerable, opening a breach in the structure and exposing a system that was never designed to operate in a war environment. Although there were no immediate leaks or casualties, the damage compromised critical functionsespecially ventilation that controls humidity and prevents corrosion, introducing a silent but growing risk that could degrade the structure in a few years. What is still hidden under the steel. Under the damaged arch remains an environment extremely unstable: remains of the reactor, tons of nuclear fuel and melts of highly radioactive materials that continue to react slowly. The old “sarcophagus,” hastily built in 1986, was never structurally reliableand is actually completely dependent on the new cover to maintain the insulation. In other words, if that balance fails, the risk is not immediate, but potentially devastating, with the possibility of release radioactive dust that the wind could disperse throughout Europe. A “reform” as expensive as it is complex. System restore will not be neither quick nor easysince it involves working in conditions of high radiation, with strict limitations on time and exposure for operators. Temporary solutions barely contain the most urgent damage, while full restoration will require rebuilding highly specialized internal layers within a structure designed as a technical “sandwich”. We are talking about an estimated cost that exceeds 500 million of euros, a figure that reflects both the technical complexity and the hostile environment in which repairs must be carried out. The war enters Europe’s greatest nuclear risk. If you like, the incident it is not isolatedbut part of a context in which nuclear infrastructure have become exposed elements within an active conflict. Paradoxically, the Chernobyl exclusion zone that we had to protect from any danger has been the scene of military operationstroop movements and constant overflights of missiles and drones, which multiplies the risk of new impacts, whether accidental or intentional. In that scenario, even a technical failure or trajectory error could trigger consequences continental in scope. A reminder of what never ended. They remembered in a special from the Financial Times this week that, decades after the accident, Chernobyl remains the same latent threat, one that requires constant vigilance and international cooperation, and the drone impact has revealed the fragility of the systems designed to contain it. The infrastructure that was to definitively close the disastrous episode of 1986 now faces a new type of risk, thus demonstrating that nuclear safety depends not only on engineering, but also of geopolitical stabilitya (and common sense). In that delicate balance, each crack is not just a structural failure, but a warning about the limits of our ability to control the consequences of our own creations.

In the Middle Ages it was common to sleep inside wooden closets. The big question is why we stopped doing it.

by

Today the idea may seem to us claustrophobicextravagant and even a little uncomfortable, but in its day, a few centuries ago, sleeping locked in a closet was the best guarantee of spending a pleasant night. Pleasant, relaxed and comfortable. Our ancestors had so many good reasons to curl up in a kind of wooden closet with sheets that the curious thing is not that they did it, but that we—since the 20th century—have abandoned the habit. In fact, there are those who propose recover the concept in the 21st century. Although, yes, with a technological point and betting on a much more modern aesthetic than the one that was popular in the times of our great-great-great-grandparents. Beds in closets? Exact. Today it may sound strange to us. To our ancestors, not so much. As I remembered recently told the BBC, there was a time, a fairly long one, between the Middle Ages and the beginning of the 20th century, when wardrobe beds were popular throughout Europe. In the 21st century, such a piece may seem curious to us, but the names with which we designate these pieces of furniture —“box bed” or “closed bed”—cannot be more descriptive. Although there were variations, with more or less elegant models and the details could vary, these items were nothing more or less than that: drawers with beds inside. Wardrobe beds were popular enough that even today we can find some important samples or references. For example, in a museum in Wick, north of Scotland, they preserve a curious bed wardrobe of pine that helps to decorate, along with other period furniture, one of the rooms where the fishermen who arrived in the region during the herring season in the 19th century stayed. Other equally curious examples can be seen in places as diverse as Austria, Holland either France. There, in the lands of Brittany, they were known as lit-clos. Even in the Rembrandt House Museumin Amsterdam, you can see today a “drawer bed” like the one used by the painter and his wife, Saskia. The writers have told us about them Emily Bronte and Thomas Adolphus and Frances Eleanor Trollope and they have even shown them to us with their brushes Pieter de Hooch either Jacob Vrel. That’s not counting the multiple references to this type of furniture, both in stories and written texts. The representations show that its details could vary, but the philosophy was always the same: overhead cabinetswith legs and often doors or a small window that could be covered with curtains. Sometimes they even had two levels different. And they always contained beds for their owners to rest. “It is the resting place of the maid or any other member of the family. The opening, which is left as the only means of access to the interior of this retreat, is provided with sliding doors, generally (as well as the entire front of the bed) beautifully carved. So that the occupant may, if he so desires, completely enclose himself,” they related circa 1840 Thomas and Frances Trollope. From peasants to aristocrats If today it is possible to find so many references it is because, clarifies the BBCthis type of structures was quite popular in homes throughout Europe, both in Great Britain and on the continent, from medieval times until the early 20th century. The British network also points out that all types of families used them. From peasants who wanted to rest after long days in the countryside to fishermen or distinguished members of the nobility. At the end of the day, its purpose could always be the same, but among furniture beds—as is the case with furniture today—there were also relevant differences. There were simple ones. And there were some with engravings worthy of a palace. But… Why did they use them? The correct question could be another: Why do we stop using them? Over time they went out of fashion and became rarities, but for centuries they guaranteed a comfortable way to spend the night. The reason? They offered privacy, were versatile, made it possible to make good use of space and to top off their service record, they helped to spend warm evenings in homes where, as remembers the historian Roger Ekircj, it was not unusual for the sap from the logs in the fireplace or even the inkwells to freeze. The teacher remembers that between the 14th and 19th centuries Europe and part of North America suffered a Little Ice Age which froze the waters of the Thames River on almost twenty occasions. With such temperatures the prospect of locking oneself in a box at night didn’t seem like such a bad idea. Especially if you take into account that it could be shared with other people. Extravagant perhaps, in the eyes of 21st century families; but the box beds were also smart. The most elaborate ones offered a seat and drawers in which clothes could be stored, just like today’s folding couches. Not to mention that they were a great option to convert places that a priori had been designed for other purposes into bedrooms. For example, the Wick Society says that in 1980, a family from the Scottish Highlandsinstalled one of these beds in the barn so that part of its members could sleep there. The room designed for family rest had become too small and the design of the wardrobe bed gave them a great solution. TIt was also not unusual for them to be offered to seasonal workers and immigrants and for them to be shared among several family members or co-workers. Perhaps this way they would be less comfortable – not to mention privacy – but on one of the nights of the Little Ice Age that hit Europe in the 17th century with icy temperatures, those wooden sarcophagi were an effective way to avoid the cold. Or that it was at least more bearable. Perhaps that is why, even today, in 2024, there are those who look at … Read more

OpenAI’s big problem all these years has been a chronic lack of definition. Now he wants to solve it with a super app

by

OpenAI spent much of 2025 announcing new features, not new models (that also), but new products. We saw him with his Sora 2 video generator or with ChatGPT Atlas browser. Now, the company recognizes that they were diversifying too much and their plan is… to launch another app. The super app. They have an exclusive Wall Street Journal that OpenAI is preparing a desktop tool that will unify the ChatGPT app, its Codex code platform and the Atlas browser. This super app will offer agentic capabilities, not only oriented to code, but also to productivity. This is aiming directly at the business field, a field in which its rival, Anthropic is quite ahead of him. Too many products. The company’s goal with this move is to simplify the experience and reduce fragmentation between products. Speaking to the Wall Street Journal, a company spokesperson assures that it will allow them to unify the different teams, which will be able to focus their efforts on one product instead of several. In an internal note, OpenAI explicitly acknowledges that they were spreading their efforts across too many apps and needed to simplify them. The change will be led by Fidji Simo, the head of apps at OpenAI, who recently brought the employees together to give them a message: “We cannot waste this moment because we are distracted by parallel projects.” And diversifying consumes many resources, both economic and computing capacity, and OpenAI is not to be wasted none of them. Without direction. OpenAI has the most used chatbot in the world, but what they don’t have is a clear product strategy. They have wanted to be too many things at once without a clear strategyand in addition, half-abandoned products have been left along the way. The Atlas browser is the best example of this. I had all the potential to be a serious alternative to Chrome which had not yet integrated Gemini. The reality is that, five months after its launch, ChatGPT Atlas is still exclusive for Mac and also has lost functions. Something similar happened with Sora 2: they got the viral moment they were looking for, but today the app remains exclusive for users in the US and Canada. Competition where it hurts most. While OpenAI launched its video memes or its browser, the competition moved forward with a much less flashy, but better thought-out plan. According to a Menlo Ventures reportin 2023 OpenAI had a 50% share in the enterprise segment, while Anthropic had only 12. In 2025 the tables turned: Anthropic had 32% and ChatGPT 25%. If we focus only on programmers, 42% prefer Claude and only 21% ChatGPT. ChatGPT still has many more users, but the vast majority are for personal use. Financially, business users are much more valuable because they have no qualms about paying for subscriptions that often exceed $200 per month. Image crisis. In case Anthropic was not eating enough toast, the image crisis caused by the agreement with the Pentagon. ChatGPT began to lose users at a worrying ratewhile Claude was placed in the top of most downloaded applications. What they were missing.

Meta hit it big, betting everything on the metaverse. Now they have a Schrödinger metaverse

by

We often see large companies change the design of their logos. They do it to maintain consistency with the product they are promoting at that moment, but the logo is one thing and the name and the entire brand are another. Facebook fearlessly jumped into the pool in October 2021 changing its name to Metaof ‘metaverse‘. After lose tens of billions and with the metaverse buried, Meta confirmed the inevitable: it will close the Horizon Worlds platform this year. But there is a twist: after announcing the closure, they now say that they will keep it alive for a while longer. How much? Mystery. In short. One of the most iconic moments of the technology presentations was when, in a packed room, Mark Zuckerberg walked between rows of journalists wearing a Quest helmet. The metaverse had arrived, or so Zuckerberg wanted. Years later, the reality is very different from future they hoped for Facebook Goalbut the name change had already been done and had to be accepted. ‘Horizon Worlds’ was the platform on which we could lead a second life, one that nor the employees of the Meta itself they used. To the metaverse he was doing badly, extremely badand Meta tried to make it stick in every possible way taking it to mobile and integrating it with Instagram, Facebook and WhatsApp. Meta announced the plan as one to bring the metaverse everywherebut a few hours ago, Meta took the final step: he announced that on June 15 he would close ‘Horizon Worlds’ in the Quest helmets. Lowering the blind. Although the metaverse is everywhere, it is evident that the most natural way to access it is through virtual reality. However, it is clear that they are not going the way they would have liked and, in a release On Discord, the company confirmed that virtual worlds could no longer be created, published, or accessed in VR after that date. It was announced that the closure would be carried out in stages, killing applications from the Quest store starting on March 31 so that no more users can join, culminating with the definitive closure of the VR worlds on June 15. In the announcement, Meta confirmed that ‘Horizon Worlds’ will, from now on, be a mobile-only app. It seemed like the culmination of a process that, apart from burning money, has led Meta to lay off hundreds of workers and hit a 30% blow to the budget of the Reality Labs division. Schrödinger’s metaverse. But it is clear that those who are still in the metaverse did not like the news at all, to the point that Meta has had to come out to clarify the message… and back away. Although they have done it in a curious way. In a question session on Instagram, the company’s CTO, Andrew Bosworth, came to the fore to comment that the dead man is very much alive, that they have thought better of it and that ‘Horizon Worlds’ will remain in VR for “the near future.” The statements are as follows: “The ‘Horizon Unity Runtime’ games do not work on mobile, only in VR, and we will not be introducing new games. Again, most of our strategy is aimed at mobile, but people who already have games they like will be able to download the ‘Horizon Worlds’ app and use it in VR in the near future.” In the units of measurement, “near future” is not that it is very concrete, but at least it seems that they do not kill it yet due to, according to Bosworth, showing support “to the fans who have contacted us.” He has commented on it in stories (something that, conveniently, will be deleted), but here is the video: Other type of glasses. Come on, where I said I say, I say Diego and the Quest metaverse will continue to live for a while longer. As a user, I wouldn’t throw my hat in the ring because it’s clear that they are planning a closure sooner rather than later, but it is always good news that they have listened to those who continue using the platform. Because the Quest, beyond ‘Horizon World’, is an extremely interesting headset for playing and consuming content, but Meta has been betting on another type of glasses for some time. There are the Ray-Ban Meta, “normal” glasses that are used not to consume, but to create. Already in 2024 we said that Meta was giving a flip from your VR glasses to your everyday glasses because the Ray-Ban Meta is not only a tool for content creators and anyone who wants to record their daily lives: it is a device through which Meta can distribute its AI. And an extremely controversial one, based on what we now know about Where can the images we record end up? with those glasses. And AI, of course. Because if years ago it was the metaverse, now Meta’s obsession is AI. The company is focusing on this technology in which it is not very well positioned. They focused a lot on preparing and presenting very good models, but not very consumer friendly and it was the big loser of the AI ​​race last year. Their change in strategy seeks to gain a foothold in a segment in which they are already ChatGPT, Grok, Claude or the chineseand for this it has a double strategy. On the one handa super team of AI stars whose machine will have to start working at some point. On the other hand, a collaboration with NVIDIA and another with AMD to train the AI, as well as the development of own chips for inference. There is 135 billion dollars at stakean investment in one year that exceeds the total of the Metaverse and that indicates why it is logical for Meta to abandon anything that does not work for him in the slightest right now in order to allocate all possible resources to pursue the new objective.

El Niño is coming back in a big way

by

Since mid-2025, we had no news on the front: the equatorial Pacific has been governed for months by a tremendously weak, decaffeinated and boring La Niña. But things end. And this La Niña is, in fact, ending very quickly. As I write, Kevin waves are transporting heat into the eastern Pacific and major seasonal models are signaling with unprecedented fixation that El Niño is just around the corner. What’s more, they point out that the next episode of ENSO is going to be between strong and very strong before we know it. First of all… what is El Niño in 127 words. What we know as El Niño-Southern Oscillation (or ENSO) is a cyclical (although somewhat irregular) climate phenomenon that has large effects on the global climate. During the warm phase (during El Niño itself), the lack of trade winds to cool the surface causes the temperature of the Pacific waters to skyrocket. And that, precisely that, disrupts all the Earth’s weather systems, causing the thermometers of the entire planet to skyrocket. As explained from AEMET“El Niño, through different atmospheric teleconnections, gives rise to drier than normal conditions in certain parts of the world; while in others it causes more precipitation. Some countries have to deal with significant droughts and others with torrential rains.” What happened now? Something quite curious, really. In just one week, we have gone from the most absolute tranquility (60-70% chance of neutral conditions) to 80% of a strong or very strong El Niño before summer ends. What has changed, as I said above, are the ocean signals: NOAA have found signs of significant subsurface warming, and that warming is the classic first sign that something is starting to change. Basically, since the beginning of the year there have been three episodes in which warm water from the western Pacific has been moving eastward. Changes in the wind pattern have also been detected. And why does it concern experts? Because these rapid changes are very similar to what happened in 1997. The super El Niño of 97-98 was one of the strongest ENSOs in recent years and caused numerous problems: the estimates say that he alone caused damage to global economic growth of around 5.7 trillion dollars. Obviously, many things They can go wrong between now and summerbut we would be wrong if we do not pay attention to the Pacific. We are at the doors of a global food crisisthe last thing we need is for El Niño to hit the Southern Hemisphere hard during the last months of the year.

The big winner of the Hormuz blockade is the country that the West has tried to suffocate for years: Russia

by

The script was written and the West was already celebrating the definitive economic strangulation of Russia. However, geopolitics has a bad habit of blowing up office plans. Today, the world is witnessing a historical paradox: the United States has just opened the back door to Vladimir Putin’s oil to try to stop a global energy collapse. The war between the United States and Israel against Iran has set the markets on fire, pushing up barrel prices above 100 dollars. Faced with the abyss of an unprecedented crisis, diplomacy has had to surrender to the stubborn reality of infrastructure. The “digital fog” and an emergency rescue. To understand the magnitude of the paralysis you have to look at the maritime traffic monitors. As detailed Bloombergthe Strait of Hormuz has become a “digital fog.” The few ships that dare to sail do so by turning off their location transponders (AIS) and suffering constant interference and GPS spoofing (spoofing) fruit of electronic warfare. In this scenario of physical suffocation, India was on the brink of collapse. The Asian giant is heavily dependent on imports from the Middle East, and the closure of Hormuz has cut off its rennet supplies. Reuters reported last week that state refineries like MRPL (Mangalore Refinery and Petrochemicals Ltd.) have been forced to close entire processing units due to the simple and simple shortage of crude oil. The unexpected lifesaver? In a turn of events, the US administration has had to swallow its own sanctions. As confirmed The Moscow Times and it is observed in the official OFAC document (the Treasury Department’s General License 133), the United States has issued a temporary 30-day waiver, valid until April 4, 2026, allowing Indian refiners to purchase Russian oil loaded on vessels by March 5. Paradoxically, how to explain BloombergIndia had drastically reduced its purchases from Moscow at the beginning of the year after facing the threat of punitive 50% tariffs from Trump himself. Now, cornered by the crisis, dozens of Russian oil tankers that were wandering aimlessly are changing their coordinates on the high seas to come to the rescue of Indian ports. The political story versus the reality of the market. Officially, Washington tries to minimize the impact of this capitulation. In statements collected by The Kyiv Independentthe US Secretary of Energy, Chris Wright, assured that “there is no change in policy towards Russia” and that the exemption is only a “pragmatic decision.” For his part, Treasury Secretary Scott Bessent defended that this measure “will not provide significant financial benefits to the Russian government” as it is applied only to crude oil stranded at sea. But the reality of the markets tells a very different story. According to CNBCRussian crude oil of the Ural variety has gone from being sold with humiliating discounts of between 10 and 20 dollars, to being traded at a historical premium of between 2 and 4 dollars above the barrel of Brent in its deliveries to India. This injection of capital to Moscow has unleashed an internal political storm. The Democrats They have demanded Trump to immediately reverse the exemption, accusing him of strengthening an adversary. From the humanitarian field, the NGO Global Witness, cited by Guardian, has been blunt, accusing the White House of “feeding Putin’s war machine” to cover up a price crisis that the United States itself has unleashed. Putin rubs his hands. To understand the magnitude of the Russian victory, you have to look at where they were just a month ago. Bloomberg, in your market analysishighlights that Russian exports were under unprecedented pressure. The Kremlin had nearly 140 million barrels stuck in the sea (65% more than usual), and was forced into a suicidal price war against Iran to try to place its surpluses in the limited Chinese refineries. Overnight, the Hormuz blockade removed all of its Middle Eastern competition from the equation. The crisis has been a gift from heaven. From Moscow they don’t even hide. How to collect CNBCKremlin spokesman Dmitry Peskov publicly boasted to the press: “We are seeing a significant increase in demand for Russian energy resources in connection with the war in Iran,” reminding the world that Russia “remains a reliable supplier.” Hurt pride and a sea of ​​uncertainty. As Russian ships sail south, the battle of public perception rages in India. Although in the BBC estimates that the country It barely has crude oil reserves for about 25 days, the Indian government is trying to project absolute calm. As reported Mashable Indiaauthorities insist that “there is no shortage in the world.” However, on social networks the narrative is one of deep sovereignist indignation. Politicians like Rajiv Shukla cried out on social network X against American paternalism: “Who is the United States to dictate to us that we can only buy oil from Russia for a month?” Added to this is the harsh reality that there are no easy alternatives. Although Saudi Arabia or the United Arab Emirates They have pipelines to bypass the Strait of Hormuz, its maximum capacity barely covers a fraction of the 20 million barrels per day that the world has just lost. The laws of thermodynamics do not understand sanctions. This whole scenario returns us to a conclusion that We already analyzed in the recent crisis of the Druzhba pipeline in Europe. The West has spent years writing laws, imposing price caps and signing embargoes on elegant offices to isolate Russia. But geopolitics always ends up submitting to mathematics and thermodynamics. While China watches the crisis calmly, with its reserves filled to the brim after years of silent strategic purchases, the European Union and the United States have had to swallow their own sanctions in record time to avoid collapse. The energy embargo on Russia has proven to be a gigantic house of cards; It only took someone to cut off the passage through the Strait of Hormuz for everything to collapse.

The US is launching a missile capable of burying the Tomahawk on Iran. And the big question is where are you doing it from?

by

The image of an American precision strike has been linked to silhouettes taking off from the sea or from the air. However, in recent years the Army has invested billions in recovering a capability that seemed secondary: hitting very, very far… from the mainland. In that bet may lie one of the greatest transformations of modern military power. A debut that changes theater. USA has premiered in combat the so-called Precision Strike Missileits new tactical ballistic missile, within the operation against Iran. It is not a minor evolution of the former ATACMSit is rather a leap in scope and concept. With more than 500 kilometers radius (and room to grow towards 650 and even 1,000) practically doubles the depth of ground fire available until now. As in many other “premieres”, it is not symbolic, it is doctrinal. A missile to bury the Tomahawk. The PrSM flies at speeds greater than Mach 3 in the terminal phase, allowing it to arrive earlier and better penetrate hardened targets. Forehead to Tomahawkslower and subsonic, the new system greatly reduces the enemy’s reaction time and complicates interception. Additionally, two missiles fit in a single HIMARS launcher pod, meaning that double the punch per vehicle. Of course, it does not replace the Tomahawk in strategic range, but in regional scenarios it can be left in the background due to speed, survivability and response capacity against time-sensitive targets. A PrSM capsule seen in front of a US Army M142 during an exercise in Australia. The M142 carries a 227 mm rocket with six projectiles. The Persian Gulf as a platform. At this point, geography explains a good part of the movement. The Gulf has a medium width of just 250 kilometerswith American allies aligned on the western bank and Iran occupying the eastern one. With a range of 500 kilometers, a land battery located anywhere on the Arab side can cover wide swathes from Iranian territory without the need to penetrate its airspace. That makes the missile a perfect tool to support an air campaign without exposing fighters or depending exclusively on ships. A test launch of a PrSM The key question: from where? The most decisive fact remains unknown. No has been confirmed Which Gulf country has authorized the use of its soil to launch these missiles. This mystery is not technical, it is rather political. The reason? Allowing a US land battery to fire on Iran automatically makes that territory in possible objective of retaliation. Many States in the region have historically preferred discreetly support to Washington while avoiding public exposure. Put another way, the exact location of the launch determines what capital takes on the direct risk. Hunting sensitive targets. Short-range ballistic missiles are especially effective against radars, mobile launchers and air defense nodes. Plus: they can be maintained on permanent alert and strike within minutes when a target arises. In a conflict where neutralizing anti-aircraft systems is key to sustaining air superiority, the PrSM provides a ground suppression capability which until now relied heavily on aviation and naval missiles. Beyond Iran. If you also want the premiere of the PrSM send a signal to other scenarios, especially the Pacific. Its planned evolution includes anti-ship versions capable of attacking moving targets and variants with greater range that will touch the threshold of medium-range missiles. It we have counted before. The US Army wants regain prominence in long-range warfare, traditionally dominated by the Air Force and Navy. Iran, in that sense, has been the first real test bed. Cost, volume and future. It is the “but” of any ballistic missile. Each projectile can exceed a million and a half dollars, although the price has been dropping as production increases. The goal is to reach up to 400 units annuallywhich will expand the available inventory and facilitate its sustained use. With future versions that could exceed the 1,000 kilometers rangethe PrSM does not seem just a substitute for the ATACMS. It is the first stone of a terrestrial architecture that seeks to project deep power from solid ground. What is really at stake. In short, the real twist is not that the United States has launched a new missile in a war, but that it has from the ground and against Iran. If he Tomahawk has symbolized precision warfare from the sea, the PrSM aims to represent the return of the tactical ballistic missile as a flexible instrument of regional pressure. And while it is not known with certainty from what ground ally is taking off, the political dimension of that launch will continue to be as relevant as the technical one.

It is a nod to Chinese Big Tech and a message for NVIDIA

by

Huawei has arrived at the Mobile World Congress with one objective: to show the world What good have these last five years been? of vetoes and sanctions. The company has just had the second best year in its history. It seemed impossible when The United States ostracized herbut this five years has served not only to regain the throne in the enormous Chinese market, but to build something: the idea that China’s technological evolution passes through its hands. As a result of this we have the advertisement at the Barcelona fair of a line of SuperPoD supercomputers with a single objective: that the Chinese Big Tech don’t have to depend from NVIDIA. Return. Huawei has been collaborating with SMIC -the great foundry of China- to create chips. Chips that feed both your consumer devices as other high-performance ones for large-scale computing. It is clearly difficult to do this without violating Western vetoes (for example, their mobile processors do not have 5G and are less powerful than those of Qualcomm or MediaTek), but they are making progress. The symbolic thing is that They have turned resilience into their best quality. If in 2020 they competed for the market with Samsung and Apple, achieving a profit of 129,000 yuan, in 2025 registered 127 billion dollars, something impressive if we take into account that, above all, They come from the local market. In this time, Huawei has positioned itself as a lifestyle brand that has consumer devices, but also home automation and even cars. But if there is a great frontier today, it is that of artificial intelligence. And Huawei knows that it was something that had to be attacked not only from the most local perspective, but by launching a global warning. SuperPoD. Because these supercomputers, really, are not new. The company presented them in mid-September last year with a more local focus, for China. And before looking at the products, you have to see what a SuperPoD is. These are high-performance clusters that bring together thousands of specialized AI chips. And those chips are not from NVIDIA, which dominates the global conversation in AI computing, but rather their own. It’s about your Ascendsome that have been developing for years and that China is waiting like May rain to break that hegemony of NVIDIA. The idea is the same as with other technological sectors of the Asian giant: not to depend on anyone else. They are the following: Atlas 950 SuperPoD– A cluster of up to 9,192 Ascend 950DT NPUs per system with up to 1,152 TB of unified memory. TaiShan 950 SuperPoD– First general-purpose computing SuperPoD with two models: 96 cores / 192 threads or 192 cores / 384 threads for, for example, massive virtualization or critical databases. Local ecosystem. Huawei’s approach is very interesting. The Ascend is not close to the power and sophistication of NVIDIA chips, nor to CUDA technology that has become the language of AI. However, if each chip individually cannot compete for the most demanding tasks, what Huawei has thought is that these chips be scalable. To do this, they have developed a connection technology with ultra-high bandwidth that allows all these chips to be connected to each other with the aim that, in practice, it behaves like a single logical computer. This connection technology has been named UnifiedBus and, in the statement, Huawei states that the idea is to “continue defending open source and open systems to accelerate developer innovation and the prosperity of ecosystems. That is something that resonates with the Government’s objective: that its companies such as Tencent, ByteDance, Alibaba or DeepSeek, which have run into the arms of the latest NVIDIA chips As soon as the ban was lifted, they developed their technologies using ‘made in China’ solutions. Ambition at the cost of sanction. All this comes in a tremendously turbulent context. China is betting a lot on artificial intelligence and robotics as pillars of the country’s technological roadmapbut NVIDIA still has the best product. There is analysis that expose that the best of Huawei is still five times less powerful than the best of NVIDIA, and the United States has just made it clear that investment in AI is one in national security. All the mess between Anthropic and the Pentagon has to do with how the United States demands that the AI ​​of its private companies belongs to the State because they claim that the AI ​​of Chinese companies belongs to China, and China will not hesitate to do whatever it wants with that AI. Because computing power is, and will be, at the core of the AI ​​race, Huawei has shown that it is doing everything it can to deliver the best tools. And Western sanctions have only helped China ‘wake up’ and begin to shape these technological solutions at an accelerated pace. NVIDIA was clear. It remains to be seen whether customers around the world will adopt Huawei’s SuperPoD systems as an alternative to NVIDIA, but what is already on the table is that something is happening. At least, in China. In the middle of last year, the CEO of NVIDIA pointed out that before the vetoes, NVIDIA had 95% of the market share in Chinabut currently it is only 50%. These vetoes did not stop China, but rather accelerated the development of its own industry to the point that the competition, now, is fierce. In fact, the manager recently pointed out that it was absurd for the US to try to stop China with vetoes and sanctions, since China would achieve technological sovereignty sooner or later and that the ideal would be to take an economic slice while they could… and make Chinese Big Tech dependent on NVIDIA technology. And there Huawei’s approach is very curious because yes, its chips may not be the most powerful, but they are mass scalable and adaptable to the needs of each of the companies.

The big problem with putting robots everywhere is that they get lost. An engineer from Elche believes she has the solution

by

It is no surprise that we see more and more robots in our daily lives: in a restaurant bringing orders to the table, in the field as a seasonal workermaking him courier delivery competition…and that’s not to mention its applications in automation on an industrial scale. Robots don’t need to rest, they don’t have labor rights, and they don’t complain. But they get lost. And that is a real, very common problem for which a research team from the Miguel Hernández University of Elche has found solution. The context. Autonomous robots need to know where they are to function and that does not always happen: when the location reference is lost, either because someone moves it, it is turned off or the environment changes without warning, the robot is unable to recover its position. Something as normal as running out of battery can be a technical drama. This phenomenon is not something isolated, in fact it even has a name in robotics: the “kidnapped robot problem“. Although we see more and more robots everywhere, this incident is a pending issue that has not been resolved in a robust way for decades. Without going any further, because resorting to GPS is something that can fail in settings such as indoors or near tall buildings. As deepens Míriam Máximolead author of the article: “It is a classic problem and very difficult to solve, especially in large environments.” The solution. What the team from the University of Elche has implemented is MCL-DLF, the acronym for Monte Carlo Localization – Deep Local Feature, a system that combines two technologies: on the one hand, a 3D LiDAR that emits laser pulses to draw a three-dimensional map of the environment similar to that of robot vacuum cleaners. On the other hand, an artificial intelligence that learns which elements of the environment are most useful for orientation. Why is it important. Because having a reliable location system is essential for any robotic deployment in real life: autonomous vehicles, delivery and logistics, assistance… its presence may be increasingly common, but it is still tremendously dependent on supervision: knowing where it is is essential for it to operate safely. The implemented method also introduces an important change: it is independent, in that it does not require external infrastructure to function like GPS, so its base is more robust and versatile in the face of different use scenarios in the real world. How it works. Its approach is hierarchical, so it first recognizes large structures and then fine details, similar to how people do. When you arrive at an unknown place, first you keep the essentials: what neighborhood you are in, for example. Then you look for more specific references to refine further. Furthermore, the system does not play everything on one card: it maintains several position hypotheses simultaneously and discards or refines them as the sensor captures more information. Tests carried out for months on the university campus with different lighting conditions, vegetation or simply the weather have shown more consistency than conventional methods. A good start with pending subjects. Beyond its promising results, the most striking thing about this research is its commitment to sensory autonomy: it does not depend on networks of beacons or GPS, but on its own sensors. This makes it a potentially more versatile system. However, it faces the great historical challenge of robot placement: how fragile it is in the face of changing environments. It is true that they have tested it in different conditions, but it has been within the campus: making the leap to more complex and constantly changing environments is their litmus test, in addition to additional validation in extreme conditions. Finally, before an eventual real commercial deployment, we will have to see how it integrates with other navigation systems and its computational cost.

MicroLED promises to be the Holy Grail of televisions. That is your big problem today.

by

There are technologies that are born with enormous promise. He MicroLED is one of them. Since Samsung introduced “The Wall” at CES 2018the sector has been telling us for years that this technology is going to revolutionize the way we watch television. And he is right. The problem is that this revolution has not reached anyone’s living room. who is not a billionaire. The technology has become the Holy Grail of the television industry, but the enormous cost of its manufacture means that only the most exclusive models and, let’s say it without frills, extremely expensive, can integrate this technology. Unlike what has happened with OLED or MiniLED, manufacturers have not managed to reduce production costs of these panels to make them competitive in mass manufacturing. What is MicroLED and why is it so special? To understand MicroLED you have to know how current screens work. Traditional LED TVs have a layer of pixels that filters light coming from an array of LED lights installed on the back. It is, therefore, a backlighting technology that offers very good brightness power. The problem is that when those screens need to display pure black, the screen can’t turn off pixel by pixel, so it turns off areas of those rear LEDs. The more dimming zones you have, the better the light control and the more control over the blacks you have. Even so, it is inevitable that some light will sneak in. It’s not really black. The result is very dark grays at best. The technology OLED solved that problem years ago, making each pixel on the screen emit its own light that can be turned off individually. Here, the result is a perfect contrast, but it has its own limits. The LED diodes that make up each pixel are organic, so they degrade over time and are susceptible to burn-in, leaving a permanent mark on the screen after many hours with a static image on the screen. In this sense, the promise of MicroLED technology is to provide the perfect balance between OLED and LED, but without any of their drawbacks. Like OLED, it uses microscopic LEDs as a pixel, but made with inorganic materials that are much more stable and resistant to burning. In this way, the screens MicroLEDs are capable of reaching OLED contrast levelsbut with a much higher shine and with a useful life that is measured in decades. It is literally the best of all worlds. And there is also its trap. The problem: manufacturing the MicroLED is a nightmare A 4K display has about 8.3 million pixels. In the latest MicroLED panels, each of those pixels needs three individual LEDs, leaving us with almost 25 million microscopic chips that must be manufactured, placed and connected with nanometric precision on a panel the size of a television screen. This level of miniaturization required by MicroLED has limited its production to large-inch formats before the challenge it poses fit so many millions of diodes into a 55″ or 65″ panel. The process of mass transfer of these chips, what the industry calls mass transferis extraordinarily complex, and today, also extraordinarily expensive. How much expensive? To put it in context, one of the few MicroLED models that can be purchased in stores is a 89 inch Samsung and has a sale price of 109,000 euros. He LG Magnitaimed at the extreme luxury market, was around 230,000 euros in sizes of 118 and 136 inches. That price range makes them unviable as home televisions (at least for most mortals’ homes). Hence its market figures are very small at present. In all of 2024, they were manufactured less than 1,000 units of MicroLED televisions in the entire world. Samsung sells that many conventional televisions in a matter of minutes. However, although these panels do not reach the living rooms, it does not mean that the MicroLED is stagnant. In fact, it is in development. This technology is growing strongly in those niches where price matters less than performance. In large format signage it has been the standard for years. film and television studio fundslobbies of luxury buildings or private movie theaters. In automotive, the dashboards of the future want bright, durable and efficient screens. And in the wearables segment and augmented reality, both Apple and Samsung have been investing for some time in bringing MicroLED to smart watches and AR glasses, where extreme pixel density is critical and having smaller production volumes makes the cost more manageable. As indicated in an analysis According to Yole Group, the global MicroLED market could grow to nearly $5 billion in revenue by 2032, although most of that will come from those niche segments, not the living room TV. There are MicroLED and “MicroLED” The high production cost made manufacturers explore other ways to make this technology profitable and evolve. One of the solutions was to use as backlight system behind an LCD panel, rather than as self-emissive pixels. Strictly speaking, although the latter have MicroLED technology, they should not be considered as such. However, some brands use it interchangeably in their trade names for advertising purposes. By having a smaller scale, MicroLEDs allow much better control of light and enhancing the colors, but they still require an LCD panel that separates the colors of each subpixel. That is, it would act more like a MiniLED or a conventional LED than an OLED. The good news is that, as brands showed like Hisense and Samsung have already evolved MicroLED technology with white diodes, towards the RGB MicroLEDwhich already has a self-emissive RGB diode for each pixel that, now, would be closer to the operation of an OLED. This evolution, as before MicroLEDs they made other technologiesrepresents the first sign that these panels are beginning a path of optimization to reduce production costs. In fact, the models launched by Samsung during the last CES 2026 It would be around $30,000.. It seems like an exorbitant figure for a television, but it must be taken into … Read more
