Japan sent the wrong creature to eradicate snakes from an island. The disaster was so big that it took half a century to solve it

by

Once again, desperate situations lead to extreme measures. Save a species sometimes it involves “exterminating” another. We have seen it in South Africa and his plan to annihilate miceeither injecting radioactive material into the horns of rhinosthe cases of hunt the wild cator the plan for exterminate half a million owls. However, sometimes things do not go as governments imagine. In Japan they know it perfectly. The incident of ’79. The story begins in 1979 on the Japanese island of Amami Ōshima, located in the Kagoshima prefecture. That year, Amami’s rabbit is rediscovered (Pentalagus furnessi), an endemic species and considered a “living fossil” due to its evolutionary antiquity. Before the discovery, the rabbit was thought to be on the brink of extinction due to habitat loss and hunting. The discovery marked a before and after for the conservation of the species and highlighted the importance of protecting the natural environment of the island, home to many other unique species. An event that also highlighted the need for greater conservation efforts at Amami Ōshima, for example trying to eradicate or control the snake population. A wrong “bomb”. Thus, a few months later, Japan launched a plan. Introduces around 30 mongooses to the island with the intention of ending the population of snakes, specifically the habu (Trimeresurus flavoviridis), which represented a threat to the local inhabitants. The idea, on paper, was a seamless plan: that the mongooses, which are natural predators of snakes, would reduce the number of habus and improve security on the island at all levels. However, that project was far from infallible. The mongoose was not the ideal creature to eradicate snakes. Firstly, because they are animals active during the day, therefore, they could not catch the nocturnal habu snakes, which continued to inhabit the following decades without problem. What happened as a result had an enormous ecological impact. A specimen of Trimeresurus flavoviridis Predation of endemic species. Thus, during the day, instead of focusing on the habu snakes, the mongooses began to prey on a wide range of native species, including several that had no natural enemies on the island until then. That seriously affected the local fauna, especially endemic and endangered species, like the same Amami rabbit that had just been happily announced months ago. Hundreds of thousands of mongooses. The situation reached such a point that the mongooses, brought in to eradicate one pest, had become an even larger and more dangerous one, one that It reached around 10,000 copies. at its peak around the year 2000. The truth is that Japan had already started a mongoose control project in 1993 that was expanded over time. As? Around 30,000 traps were set on the island to capture the animals and cameras with sensors were installed to monitor them. In addition, local residents formed the so-called Amami Mongoose Bustersa team specialized in capturing mongooses (they captured thousands). The end? In 2018, the last official capture of a mongoose on the island occurred. It occurred in the month of April, and since no creature has been captured for a long period of time, the expert panel, which is tasked with determining whether the animal is eradicated from the island, estimated that the eradication rate was between 98.8 and 99.8% in February last year, reaching a preliminary conclusion that it is reasonable to say/think that mongooses are eradicated from the island under the current circumstances. Finally, on September 3, 2024, Japan’s Ministry of Environment declared eradication of non-native mongooses on the island of Amami-Oshima, declared a World Natural Heritage Site by UNESCO. The statement was based on the opinion of the expert group on scientific grounds, taking into account that the capture of mongooses has not been confirmed for more than six years since the last one in April 2018. A unique case. The ministry itself did not hide the disaster that was the attempt to control the snakes in 1979. In fact, and as the administration has announced, it is one of the largest cases in the world in which non-native mongooses that had been established for so long have been eradicated. After the statement, the government explained that it will remove the traps that were placed on the island, although it will continue to monitor with cameras to prevent a new group of these small creatures from entering again. After all, if it took half a century to get them out of there, any contingency method is more than understandable.

The big problem with nuclear energy has always been its waste. Russia can now recycle them up to five times

by

A nuclear reactor operating for 60 years using a closed system of three circulating fuel loads, subjected to cleaning processes and specific recharges in each cycle. What until recently seemed like an unattainable technical utopia for the energy industry is the reality that Russia’s latest technological breakthrough points to. The historic Achilles heel of nuclear fission—radioactive waste—is about to take a radical turn to become an almost inexhaustible resource. The magnitude of the test. The press release of Atom Media explains that Unit 1 of the Balakovo nuclear power plant (operated by Rosatom’s energy division) has just made history. They have successfully removed the last three lead test assemblies from an innovative fuel dubbed REMIX. These groups have completed three operating cycles of 18 months each. We are talking about 54 months performing at maximum capacity in a Russian commercial reactor type VVER-1000, thus exhausting its standard useful life. This puts the finishing touch to a demanding pilot program which started at the end of 2021 when the first six experimental rods were introduced into the reactor core. The resounding success. The most impressive thing about this milestone is not just that the fuel works, but where it works. Unlike other experiments designed for new generation fast reactors, REMIX fuel can be used in light water thermal reactors already operating massively around the planet. And without the need to modify its design or add costly security measures. The rehearsal went flawlessly. Yuri Ryzhkov, deputy chief engineer of the Balakovo power plant, detailed: “After each cycle, the fuel rods and structural elements were inspected using the television camera of the refueling machine. No deviations were detected during operation; neutron, physical and service characteristics remained within the design limits.” The science behind REMIX. But what exactly is this material? REMIX comes from Regenerated Mixture (Regenerated Mixture). Instead of using the usual natural enriched uranium, Russian scientists have created a matrix pellet that mixes regenerated uranium and plutonium (both recovered from already spent and reprocessed nuclear fuel), seasoned with some fresh enriched uranium. The technical key to the process is in the proportion: it maintains a very low level of plutonium, up to 1.5%. Thanks to this exact formulation, its neutron spectrum is practically identical to that of standard fuel. For practical purposes, the reactor core behaves the same and does not even “notice” the difference. The cleaning process. It is the circular economy taken to the atomic extreme. The magazine World Nuclear Newyes explains that this recycling cycle can be repeated up to five times. With each pass, the industry reprocesses the material to separate the useful uranium and plutonium from the fission products, which constitute the true radioactive waste. This useless waste is extracted and vitrified (encapsulated in glass) to be permanently and safely buried in geological deposits, while the useful fuel mixture is reintroduced into the reactor. The vision of the balanced cycle. Now it’s time for the laboratory and certification phase, where the irradiated material, now resting in cooling pools, will travel to the Atomic Reactor Research Institute in Dimitrovgrad for exhaustive analysis. Alexander Ugryumov, Vice President of R&D at TVEL (Rosatom’s fuel subsidiary), He announced that after these studies They will be able to bring the product to the market. The next evolutionary step will be to test mixtures with depleted uranium and up to 5% plutonium. All this is part of what Rosatom has called the “Balanced Nuclear Fuel Cycle” (NFC). The goal is to drastically reduce the volume and danger of radioactive waste, solving the historic problem of long-term storage for future generations and guaranteeing a truly sustainable production system. An impact on a global scale. Although the technical success is undeniable and the operational milestone in a commercial reactor is demonstrated, the mass adoption of this technology on a global level will largely depend on the commercialization costs and the economic viability of large-scale reprocessing; factors that the industry must demonstrate after the current qualification phase. However, if Rosatom manages to market REMIX at competitive prices, the global energy situation could take an unprecedented turn. We are not talking about a niche experiment. The data provided by Atom Media illustrate this magnitude: TVEL currently supplies fuel to more than 70 power reactors in 15 countries. Today, one in six reactors in the world operates with its technology. Moving from a linear “use and bury” industry to a closed loop where nuclear resources have multiple lives would not only dramatically expand the planet’s energy reserves, but could forever redefine the ecological viability of nuclear energy.

What is SMIC, China’s big chip manufacturer, doing right now? According to the US, sell them to Iran for the war

by

The war in Iran continues. On the one hand it is said that it is almost finished, but on the other we have the shipment of thousands of American paratroopersmore calls for support and one sided offensives and from another. But in almost any conflict, not only those in the countries involved come into play, but also the allies. And the United States has leveled a pretty serious accusation against China: SMIC is selling chips to Iran. Well, “almost certainly.” SMIC in the spotlight. Semiconductor Manufacturing International Corp the great Chinese semiconductor foundry. Included in the blacklist of the United States government along with Huaweihas managed to develop advanced chips in record time. They have not only challenged everything the US thought they could dobut that association with Huawei and the country’s push for the technology industry have made it one of the spearheads of China’s technological sovereignty. That SMIC has been able to manufacture advanced chips when it was denied access to cutting-edge technology is something that upsets the US government, which reiterated the sanction and keeping the company on the blacklist for alleged ties to the Chinese government. And the latest accusations are not going to relax the tension. ANDUSA says yes. SMIC makes chips and obviously sells chips. And the United States claims that they are supplying technology to Iran. a few days ago, Reuters published an article in which it included two statements by “two senior officials in the Trump Administration” that suggested that Beijing, perhaps, is not staying as far away from the Iran war as they would have us believe. In the article they state that SMIC has been sending chip manufacturing tools to the Iranian army. This raised questions about Beijing’s stance in the conflict, with officials noting – on condition of anonymity – that the company began shipping the tools about a year ago and that they have “no reason to believe shipments have stopped.” A year ago, the United States was not at war with Iran, and China has long maintained a normal trade situation with Iran. US officials note that, in addition, “they have almost certainly also technically trained Iran on semiconductor technology.” And let’s remember that these chips are in everything: from routers to missiles. China says no. The Reuters article does not give any further information or details on whether Iranian tools that included US technology have been confiscated –something that does occur in other conflicts– and neither the Chinese embassy in Washington, SMIC or an Iranian spokesperson at the UN responded to requests for comment. Who has left Lin Jian, the spokesperson for China’s Ministry of Foreign Affairs, spoke out and did not hesitate to classify the report as “false information.” He accused certain media outlets of launching self-serving news and then classifying all reports as “false information.” On this issue, China has been caught between two waters, first condemning the assassination of Ayatollah Ali Khameini by the Israeli and US forcesbut also expressing his rejection of the Iran attacks on Gulf states that house US bases. Back in focus. Beyond Iran, the United States accusations are part of an operation that began a few years ago. The veto of Huawei marked the beginning of the current trade war between China and the United States, but it also marked China’s ‘awakening’ in technological matters, quest for sovereignty and a technological war that branched into chips, robotics, energy, communications, artificial intelligence and in the military arm. SMIC is the large Chinese manufacturer that defied US vetoes by managing to manufacture the chip of the Huawei Mate 60 Pro before whom The US authorities could not believe and, if they manage to demonstrate that they are involved in supporting Israel when China is not actively participating in the conflict, they will have more reasons to intensify the vetoes and sanctions. And all this is framed in a current situation in which Trump and Xi Jinping will meet in a few days to discuss international relations and where the purchase of American technology by China is expected to be one of the points of the day, with NVIDIA very interested in biting a piece of the $50 billion pie that the Asian giant represents.

Big Tech has entrusted the keys to its kingdom to NVIDIA. Now they want the keys back

by

NVIDIA is no longer a gaming graphics card company: NVIDIA is a ubiquitous company. That means it is the baby at the baptism, the bride at the wedding and the cement of the manufacturing industry. artificial intelligence. Your hardware is in the most powerful data centers on the planethis software controls everything and your money invest in any company that has something to say in AI. Big Tech (and everyone) is blindly trusting NVIDIA and has been given the keys to the house, but something is changing. And now they want the keys back to regain control. All the spotlights. Microsoft, Amazon, Google and Meta have bought hundreds of thousands of NVIDIA GPUs to shape your AI aspirations. At some point many began to develop their own hardware, but in the end NVIDIA’s was everywhere and was the one that gave the most guarantees, so they “gave up.” Apple, curiously, opted for Amazon. And not just the big ones. OpenAI, Anthropic, Mistral or xAI are purely AI companies that They bet very heavily on NVIDIA from the beginning. Its hardware is the one that leads the way, the one that Western and Chinese companies want and the one that has such a brutal demand that it has elevated the company as the best client of TSMC and Samsung. amd. But no one likes to have all their eggs in one basket, and those same names are moving. From a position of absolute dominance, in a short time we can move to another in which the hardware market is much more diversified. AMD is NVIDIA’s great historical rival in the PC gaming segment (and in consoles), but although they were out of the conversation for a few years, they have returned with force. They have the hardware and are moving to get the same memory that NVIDIA has (and Samsung wins more than anyone else) and contracts as juicy as the one they achieved recently with Meta. The big rival also has deep pockets and is committed to taking a piece of the AI ​​pie. The Chinese threat. On the other side of the world we have China. We have said on numerous occasions that China is on to other things when we talk about AI. If the West pursues the AGI (with questionable claims like it’s already here), to China doesn’t care exactly. They want fast chips that allow them to create accessible and monetizable models in the short term. But they also have Huawei, the company that has become the spearhead of the Chinese technology industry thanks to its collaboration with foundries such as SMIC is allowing, in an unthinkable way due to vetoes, can develop advanced chips. The development of cutting-edge chips still needs to be achieved, but Huawei already has more powerful inference chips than NVIDIA’s H20, according to them, and a supercluster for training. Taking back control. Because in that term, “inference”, is where the current key is. AI training is important because it is what allows the model to then have the data and have a wardrobe to pull from, but inference is the final layer, which processes the user’s request to provide a response. There is not so much raw power needed, and that is what almost all the companies mentioned above are taking advantage of. Amazon, Google or Meta have programs in which they are actively researching or developing chips proper for inference. OpenAI has signed an agreement with Broadcom to supply chips and xAI along with other companies Musk also has its own chips and they plan to open factories. And in China things are no different with Cambricon wanting to be a local alternative to NVIDIA and giants like Alibaba either ByteDance getting into chip design. Groq. Given this, do you think NVIDIA is standing still? Among their hardware proposals, they have Groq, an inference accelerator that is designed for, next to Vera Rubinprocess a large amount of data at enormous speed. Groq was an unknown in the world of AI – until NVIDIA licensed it – and specialized from the beginning in that: chips with minimal latency for inference. The key is in the architecture of its chips and it was a piece that was missing from the NVIDIA catalog and shows that, although the rest want the keys back, the one that already had them may have made a backup copy to continue being the reference. Because they may all be preparing their chips, but while they arrive, NVIDIA is already there and, in fact, with Groq it seeks to sneak into theThe $50 billion pie: China. Problem for NVIDIA. But of course, that’s part of the story. The other is that NVIDIA also has all its eggs in one basket: that of AI. In the middle of last year we already mentioned that six customers represent 85% of all NVIDIA revenue in the previous quarter. It is an absolute nonsense that shows that, if there is a shift in technology, a puncture of the bubble or a new player that arrives strongly, the situation for NVIDIA may not be so favorable. The question is whether a regime change can come and everything will be allowed to collapse like a house of cards. The uncomfortable thing is that an absurd amount of money is being invested and it’s not something that can escalate forever.

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.
