Spain is burning and its nuclear power plants notice it. This is your strategy to endure

by

Spain is sweating again. extreme temperatures At the end of June, alarm bells have gone off in a good part of the country, and the Spanish nuclear park, responsible for about 20% of electricity what we consume, is not alien to this phenomenon. However, it is worth clarifying something from the beginning: whether a plant reduces its power or stops during a heat wave has nothing to do with a security failure. The seven nuclear reactors in operation in Spain (Almaraz I and II, Ascó I and II, Cofrentes, Trillo and Vandellós II) have been dealing with demanding summers for several decades, and their cooling systems were designed precisely with scenarios like this in mind. The Nuclear Safety Council publishes in real time the operational status of each plant, so anyone can check how they are responding. The key is in the external cooling circuitresponsible for evacuating the heat dissipated by the electricity generation process into the environment. In pressurized water plants, such as Almaraz, Ascó and Vandellós II, this circuit is the third in the installation, independent of the primary (which surrounds the core) and the secondary (which moves the turbine). Cofrentes, the only Spanish plant with a boiling water reactor, has a different architecture, a direct cycle, but it also depends on that same external circuit to cool the condenser. And this is where each plant plays its own cards depending on its geographical location. Three ways to beat the heat Ascó I and II, Cofrentes and Trillo are fed by river water, but they do not return it directly to the riverbed after using it. First, it passes by the cooling towers, those structures more than 160 meters high that we have described so many times when explaining the internal workings of a nuclear power plantand that dissipate heat into the air by convection and evaporation before any pouring. This drastically reduces the amount of water they need to extract from the river, up to twenty or thirty times less than if they did not have that tower. The sea has a thermal stability much greater than that of a river Almaraz represents a particular case because it does not depend on the flow of a natural river. It uses the artificial Arrocampo reservoir, conceived as a closed system that acts as a large heat exchanger. This independence of the river regime allows it continue operating normally even when temperatures soar, something especially relevant in a plant that will be the first to shut down: Almaraz I will close in November 2027 according to the current government calendar. Vandellós II draws on another resource: the water of the Mediterranean. The sea has a thermal stability much greater than that of a river, so it absorbs heat without its temperature rising appreciably. And, what’s more, it varies much less during heat waves. It is the same thermodynamic logic that explains why so many power plants in the world, from those that are cooled with seawater to those that use closed circuits like the one in Almaraz, prioritize the thermal stability of the cold source over any other consideration. When safety forces you to stop What can happen, and in fact happens quite frequently during the strictest summers, is that a nuclear power plant reduces its power or stops temporarily. The reason is not to protect the reactor, but the aquatic ecosystem. And the regulations limit the temperature at which water can be returned to a river or the sea, and if these limits are close to being exceeded, the facility prefers to slow down rather than breach them. It is an environmental decision, not a safety emergency. Meanwhile, the clock of the Spanish nuclear blackout continues to tick in parallel to these episodes of extreme heat. The current calendar starts in 2027 with Almaraz I, followed by Almaraz II in 2028. In 2030 it will be the turn of Ascó I and Cofrentes; Ascó II will close in 2032; and The process will be closed in 2035 with Vandellós II and Trillo, the last two plants to go out. Until then, each summer will be another test of resistance for a park that continues to provide a fifth of the national electricity.

“Will I notice much of a change when going from a Galaxy S23 Ultra to a S26 Ultra?”

by

How often do you change your mobile phone? This is a question that we all ask ourselves on more than one occasion, because if we are going to spend a good amount of money on a new high-end device we like to notice a changean evolutionary leap between the previous mobile phone and the current one. In this direction was one of the questions that a xatakero asked us in our Discord who decided to take advantage The Officeone of the advantages of Xataka Xtraour subscription to access exclusive newsletters, raffles, promotions and other exclusive advantages. In this case, what we offer is a direct line with us to resolve questions like this. The xatakero told us that it came from a Samsung Galaxy S23 Ultra, and he wanted to know yes I would notice a lot of change when passing to a Galaxy S26 Ultra of 1 TB. We are going to tell you what our colleague Alex Alcolea, an expert in hardware, image and sound, and who precisely made our Galaxy S26 Ultra review. The question How do you see the purchase of a 1 TB Samsung Galaxy S26 Ultra coming from an S23 Ultra? Will I notice much change? Thank you. Our response Photo: Xataka Updating your mobile phone is a notable investment, which is why many of us are interested in measuring the extent to which we are going to notice a radical change. The more time passes between one mobile phone and another, the greater the jump you will notice, but those who use their mobile phone very actively are often tempted to update it sooner. Very good! This is Alex from Xataka… and whoever is with the S26 Ultra. Complicated request because it is already part of a spectacular mobile. My opinion after trying it at the event and at home these days is that you are not going to notice a giant leap, but you are going to have a better mobile phone in practically everything (except for the Bluetooth functions of the S-Pen, which are not in the S26 Ultra). You’ll have more years of updates and both the telephoto and wide angle are better, but if you’re happy with the S23 Ultra, maybe I wouldn’t make the jump just yet. Of course, have you considered other options within the premium segment? I’m thinking about an OPPO Find X9 Pro or an Honor Magic8 Pro. Brutal cameras, very good screens and more battery, which I see is important for you. If you say no because you are happy with Samsung, and if I had an S23 Ultra… I would stay with it. In the end, we are talking about premium ranges and it is much more difficult to notice the change than between an S23 and a non-Ultra S26, for example, or between two mid-ranges from the same years. Do you have more questions like this? The subscribers of Xataka Xtra You can send us your questions and our team will respond personally. And if you are already a subscriber, remember this advantage and that you can ask us whenever you want.

The current that warms Europe will weaken by 51% before the end of the century. And Spain, according to experts, is already beginning to notice

by

“The 5% chance just became 50%.” This quote from Stefan Rahmstorf, the world’s leading expert on the collapse of the AMOC, describes the change it introduces the study just published by the University of BordeauxIt’s this April 15th. But the story goes beyond the number: it is the latest installment of the great climate debate of the decade. A debate that, whoever wins, we are all losing. What exactly is AMOC and why do we care? The Atlantic Meridional Overturning Circulation is the North Atlantic branch of the thermohaline circulation. Since the sun does not heat the sea equally everywhere and freshwater flows reach the ocean at very specific points, this is the basic mechanism by which the oceans balance differences in temperature and salinity. The AMOC is a good example of this regulation. After all, as explained from AEMETit is an “Atlantic basin-scale north-south ocean flow that begins with cold sea water sinking to the bottom off Greenland, subsequently flowing south, and being replaced by warmer water flowing at the surface from the south, transferring heat from the tropics to the east coast of North America and the west coast of Europe.” Therefore, it is a key mechanism and if it stops, as studies began to say a decade ago, the problems for Europe would be enormous. Huge? “Without it, Western Europe and eastern North America would cool significantly, with a host of potential adverse effects,” said Sánchez Laulhé. We talk about a “widespread cooling throughout the North Atlantic and northern hemisphere in general” that would collapse the temperature in Europe would drop several degrees and cause a “strengthening of winter storms, with more and more powerful explosive cyclogenesis” and a “greater proportion of precipitation falling in the form of snow throughout Europe.” However, scientists do not fully agree. In 2021, the IPCC said the AMOC was “unlikely” to collapse. In 2023, the Ditlevsens not only said that it was a probable scenario, but that they set the first date for the collapse. In 2024, 44 signatories They asked to take the problem seriously. But in January 2025 Terhaar, Vogt and Foukal said which, in short, had not weakened since 1063. Now, the University of Bordeaux states that the AMOC will weaken by around 51% by the end of the century with a confidence level of 90%, under the intermediate emissions scenario. What can already be seen. French researchers they are right in which the most recognizable observational signal of the weakening of the AMOC is the “cold spot” of the subpolar Atlantic south of Greenland. In the midst of climate change, “the only point on the planet that has cooled in the last century.” However, we are also not clear what that really means. And there is the key. So will Europe freeze? Probably, but that’s not what’s interesting. Throughout the history of the Atlantic it has been passed many times. The question is whether it will be soon, if it will be our fault, if we can avoid it and what consequences it will have. Be that as it may, Spain will not be the most affected, but it will be. It is being. Stefan Rahmstorf, for example, said last year at the Autonomous University of Madrid that “the slowdown of the AMOC is already having impacts in Spain.” You just have to know how to read the signs.

70% of the world’s salmon comes from farms and their meat should be gray. The industry has been making sure you don’t notice for decades

by

In the heart of Tjuvholmen, a small neighborhood located on an even smaller peninsula that runs from Aker Brygge towards the Oslo Fjord, lies The Salmon. It is a restaurant, yes; but above all, it is an interpretation center for Norwegian salmon. There, just before enjoying two dozen different preparations, facilitators explain in detail “the entire salmon process – from smoking to export” and explain to diners “the historical development of salmon farming.” And it is logical. 70% of the salmon consumed in the world comes from aquaculture. Only in the North Atlantic, farms produced more than three million of metric tons in 2025 and Norway is (by far) the main producer. They explain all this in The Salmon; What they don’t explain is the color. Le Salmon, 1866–1869, by Édouard Manet The color? Salmon, in the cultural imagination of the entire world, has a very specific color: a pinkish-orange which, in short, is what we have been calling salmon color. The curious thing is that, under normal conditions, the meat of farmed salmon would be pale gray or whitish. And the reason is very simple: the characteristic color of wild salmon depends on the diet. They are big fans of krill, shrimp and other crustaceans which, in turn, feed on microalgae that produce astaxanthin. That’s what gives them the color. Instead, farmed salmon are fed feed composed of fishmeal, oil, soy, corn gluten and other poultry by-products. None of them have astaxanthin naturally and, therefore, they could not acquire their iconic color. And that, of course, is a problem. Early farmed salmon producers realized that color was difficult to manage. It is true that there is a wild salmon native to Alaska that does not naturally fix astaxanthin in its meat and is sold as a gourmet product. But that is one thing and trying to convince millions of people that this farmed pale salmon is the same (or better) than the wild one is another. Since the 1980s, researchers and producers got to work, discovered the origin of the problem and introduced chemically synthesized astaxanthin into the food chain of farmed salmon. It’s not cheap: these additives represent between 6 and 20% of the cost total feed. But it is necessary. And, by the way, they “tint” them, like the Astaxanthin is a powerful antioxidantfish improve liver function, immune response, fertility and resistance to oxidative stress. And why should we care about all this? Spain is the second largest consumer of fish and seafood in the EU; Salmon, in fact, is one of the most consumed species. The color of salmon is something well known (and completely safe), but it is not something that is usually advertised: the fear of growing distrust towards farmed fish is always there. One of the great food paradoxes of our time. Producers, in fact, have been saying for years that they would lower the amount of astaxanthin if consumers agreed to buy paler salmon. But that doesn’t seem like it’s going to happen: as we’ve seen time and time again, food depends critically on fashions and trends. this pink is in fashion.

If China invades Taiwan, Taiwan will not notice because a drone has been disguised as an optical illusion for months

by

In modern aviation, each aircraft carries a unique “digital license plate” that identifies it to the world in real time. It makes perfect sense. It is a system designed to provide transparency and security, but it also demonstrates a most disturbing paradox: what appears on a screen is not always what is really flying. China has just put it into practice. A bird, a fighter or a drone. A Reuters investigation has revealed that, since last August, at least 23 flights over the South China Sea have been registered under the callsign YILO4200, associated with a long-range Chinese military drone, although the signals it emitted told a different story. It happens that on civil radars it appeared as a sanctioned Belarusian freighter, also as a British Typhoon fighterlike a North Korean plane or even like a Western executive jet. These were not specific errors or programming errors. Was a deliberate impersonation of air identities by manipulating 24-bit transponder codes that identify position, course and speed. “We have never seen anything like this.” The middle counted that open intelligence analysts and those responsible for aerial tracking platforms agreed on something unusual: this pattern was unprecedented. It was not the classic drone flying “in the dark” without emitting a signal. It was just the opposite. He flew showing a false identity, changing it even in the middle of the journey, testing in real time to what extent he could “dirty” the aerial chart. “We had never seen anything like this,” summarized one of the experts who analyzed the data. It didn’t seem like an accident or a technical anomaly. It seemed like a conscious attempt at operational deception. The ultimate optical illusion. The drone, identified as a Wing Loong 2 With a 20-meter wingspan, it took off from Hainan and traced star- or hourglass-shaped patterns for hours over sensitive areas, including naval routes and areas frequented by submarines. In one of the missions the identity of a Typhoon of the RAF with that of three other aircraft in just twenty minutes before virtually “landing” like the Belarusian plane. On another occasion he posed as that same freighter while the real aircraft was simultaneously taking off in Europe. It was a full-fledged aerial optical illusion sustained for months. Taiwan as a backdrop. Not only that. Apparently, the trajectories were not random. Many were projected towards the Bashi channelcritical point between Taiwan and the Philippinesand when superimposed on a map of the island they crossed areas of military interest around Taipei and its southern coast. In fact, they also brushed against American and Japanese bases in Okinawa and the Ryukyu. It wasn’t just about surveillance. The pattern therefore suggests a digital rehearsal to a bigger stagea test of how to generate confusion in the early stages of a crisis in the Strait. Confusion in decisive milliseconds. They remembered in research that, in highly automated conflicts, milliseconds can separate detection from firing. Introducing noise, false identities and contradictory echoes can delay critical decisions and overwhelm chains of command. Although masking would hardly completely fool advanced military radars, it can sow doubts, hide intelligence missions, or fuel disinformation operations. The key is not so much to disappear. Is seem like something else. If China invades, the warning could be a fiction. Ultimately, the most disturbing idea is not only that a drone has been eight months in disguise in front of Taiwan’s radars. It is rather that that capacity has been tested with patience, repetition and apparent impunity. If you will, if China finally decides to go beyond in Taiwannot even the island itself is going to realize at the first moment what it is seeing on its screens. Because from now on, what appears might not be what actually flies. And that is the true revolution of the movement: a possible invasion that begins, not with missiles, but with a false identity flashing on the radar. An “ally” that comes close and that in reality is not so much.

NATO’s notice to shield our electrical grid

by

The blackboard hanging behind the bar at Squat 17b, a venue in kyiv, does not list drink offerings, but instead keeps a countdown of the days Ukrainians must endure the harsh winter. Inside, the bar lacks electricity and is illuminated only by candles, while customers shiver on stools drinking beer cooled by the freezing temperatures themselves. This print, described by Financial Timesis the result of an exceptionally harsh winter, with temperatures reaching -20 degrees Celsius. What is emerging in Eastern Europe is a reality that some analysts They already describe how “thermal terror”: the cold turned into a weapon of war. Russia does not merely seek to degrade Ukrainian military capabilities; It deliberately targets substations, power plants and distribution networks to make everyday life physically unfeasible. Heating, electricity and water become strategic objectives. Away from the trenches, the front line has moved to the transformers and electrical substations. In the first weeks of the year, Russian forces They have attacked the Ukrainian energy sector more than 200 times. Russia has launched coordinated waves of up to 40 missiles and 400 drones in a single night, seeking to overwhelm air defense systems. Ukraine lost up to two-thirds of its electricity generation capacity after the first months of bombing. And yet, the infrastructure resists. The new frontier of sabotage Faced with the increase in physical and hybrid threats, the European electricity industry has begun to issue clear warnings. “The last year has shown us that continuing with the current model in Europe is no longer an option,” said Leonhard Birnbaum, president of Eurelectric, in statements collected by Euronews. For the sector, security of electricity supply It has become a strategic issue. At the end of December, Poland’s security systems they detected what his Government described as “the strongest attack against Polish energy infrastructure in years.” The Sandworm group—a unit linked to the Russian GRU—managed to disable remote terminal units (RTUs) at at least 30 energy facilities. These RTUs do not generate electricity, but they allow substations and plants to be monitored and controlled. The attack affected plants cogeneration and systems that connect wind and solar farms with the grid. To achieve this, they used a destructive malicious code known as wiperdesigned exclusively to delete files and permanently render computers unusable. Polish Prime Minister Donald Tusk warned thathad it been completely successful, half a million people would have been left without heat in the middle of winter. This use of a wiper marks a qualitative leap: Russia has gone from simple digital espionage to destructive sabotage against critical infrastructure of a NATO member country. Physical espionage is added to the cyber threat under the sea. The Russian spy ship Yantaroperated by the Russian Deep Sea Research Directorate (GUGI), traveled for almost 100 days through the waters of the Atlantic and the Mediterranean. Their goal was to map and monitor the undersea cables that Europe and North America depend on for their digital communications and energy. These types of covert operations in the “gray zone” seek to measure NATO’s red lines and open the door to possible power or communications outages to force political negotiations. How did we get here? As the historic American general Omar Bradley recalled: “Amateurs talk tactics, professionals talk logistics.” For any developed nation today, the most critical logistics system is its energy infrastructure. For decades, Europe built a deeply dependent on imported fossil fuels. Dependency became vulnerability. As he remembered Bloombergthe European Union paid almost €22 billion in Russian fossil fuel imports last year, more than it provided in direct financial support to Ukraine. Changing models has ceased to be a climate issue and has become a pure survival instinct. The old continent has proven that filling its territory with renewable sources and electrifying the economy builds a much more solid structural wall than the old addiction to foreign fossils. And the shield is already working. A look at the data collected by the think tank Agora Energiewende In his latest report, Europe’s energy security on the path to climate neutrality, reveals a brutal cushion: the simple deployment of wind and solar technology during the last five years (2019-2024) avoided having to buy and burn 92 billion cubic meters of gas. However, this transformation introduces new risks. Modern power grids are more digital, more interconnected and more decentralized. According to the same report Agora Energiewendethe challenge is no longer just to ensure fuel supply, but to guarantee network stability, cybersecurity and industrial resilience. More nodes mean more potential entry points for attacks. Added to this is the technological dimension. How to collect Euronewsbetween 70% and 80% of the solar inverters installed in Europe come from Chinese manufacturers such as Huawei or Sungrow. In a highly digitalized system, hardware control also potentially implies software control. Energy as defense policy Faced with this vulnerability, Europe is obliged to treat energy security as a defense policy de facto. A coalition of defense experts, including retired military leaders such as British Lieutenant General Richard Nugee and Dutch General Tom Middendorp, has urged European governments to count low-carbon energy spending against NATO’s target of allocating 1.5% of GDP to critical infrastructure and civil resilience. In statements collected by Guardianretired Lt. Gen. Richard Nugee said, “To have a strong military deterrent we need a resilient homeland. And low-carbon energy is a critical component.” According to Bloombergthis vision is gaining ground in the European strategic debate: the energy transition is no longer just climate policy; is security architecture. The tactical key to this new defense is decentralization. Unlike large centralized plants that are easy targets for missiles, wind turbines and solar panels are much more geographically dispersed, making them significantly less vulnerable to large-scale attacks. To sustain this new model, Euroelectric proposes three fundamental pillars: Better planning: Preparedness frameworks should span the entire value chain, include all energy carriers, and anticipate long-term external threats. Massive flexibility: It will be essential to deploy new storage and demand management technologies to complement the variability of renewable energies. … Read more

Samsung opens the era of 2nm chips with the Exynos 2600. Chances are we won’t notice much

by

Samsung has announced officially the Exynos 2600 SoC. This smartphone chip is especially notable for one particular feature: it is the first to be manufactured with 2 nm photolithography. The question, of course, is whether that will change things much. Why is it important. Node jumps in photolithographic processes are especially striking because they usually lead to significant improvements in performance and efficiency. By reducing the scale it is possible to fit more transistors in the same space, which in essence ends up giving us “more for the same.” The Samsung Exynos 2600 goes precisely in that direction. The data. Samsung’s new System-on-a-Chip (SoC) boasts above all of that new 2nm GAA (Gate-All-Around) manufacturing process, and is composed of the following elements: CPU: ten cores in total. The configuration features one 3.8 GHz C1-Ultra core, three 3.25 GHz C1-Pro cores, and six 2.75 GHz C1-Pro cores. GPU: Samsung Xclipse 960 NPU: 32K MAC What can we expect. According to Samsung, this new CPU increases performance by 39% compared to the Exynos 2500. The Xclipse 960 GPU manages to double the computing capacity of its predecessor and 50% more performance in ray-tracing. And finally, the NPU allows 113% more performance than its predecessor, which will allow you to enjoy AI functions in a theoretically notable way. 320 MP sensors. Another of the differentiating elements of this SoC is the support for sensors of up to 320 MP, in addition to offering zero latency for captures of up to 108 MP. Or what is the same: you take snapshots thanks to that processing capacity. It is also compatible with 8K recording at 30 fps and 4K at 120 fps with HDR. Less throttling. One of the most important novelties of these chips is Heath Path Block technology (HPB). This system improves thermal conductivity using new materials, which reduces thermal resistance and helps the chip maintain high performance for longer. It will therefore be more difficult for us to notice drops in chip performance due to potential overheating, for example in gaming sessions with the mobile phone that integrates this SoC. If that promise is fulfilled, we would be facing a potential solution to a problem that has traditionally been criticized in Exynos chips. Will we notice anything? The truth is that current SoCs are already true computing beasts in all sections and usually give so much room for maneuver that it is difficult to notice differences between them in our daily lives. That perception is misleading, because these hardware advances allow us to take advantage of that performance and efficiency “without realizing it.” Increasingly better photos captured and processed instantly, absolute fluidity in the interface even with high resolutions and refresh rates, or of course gaming in increasingly demanding games are scenarios in which these chips do their best. remains to be seen if Google finally goes ahead with its “PC mode”an area in which having powerful chips like this can offer a user experience much closer to the usual laptop/PC. Competition for Qualcomm. Theoretically, the Samsung chip will be able to compete head to head with the Qualcomm Snapdragon 8 Elite Gen 5. Some previous leaks That’s what they pointed out, but without a doubt we could be facing a great option for a market that will certainly benefit from that competition. Prepared for the Galaxy S26. Samsung is expected to use the new Exynos 2600 in its Galaxy S26 series, although it is not clear at the moment whether that decision will be global and will depend on the region. A global commitment would allow, for example, to integrate this chip on the Galaxy S26 and use Qualcomm chips only in the S26 Ultra, but everything remains to be confirmed. Of course, that type of strategy would be the definitive litmus test for Samsung Foundry, which in recent years has clearly been one step behind in performance and efficiency compared to its competitors. In Xataka | The Samsung Galaxy S26 will be much more than a phone for Samsung: the future of Exynos depends on it

Half of Spain is on alert due to snow and yet AEMET has not issued a single red notice: what is happening here?

by

“Historical Polar Beast“, “New Philomena“, “the polar storm that threatens Spain“: Much has been written about the intrusion of cold air that is causing drops in temperatures, snowfall and trouble throughout the north of the country. And not always without reason. In fact, the Junta de Castilla y León has declared the alert for snowfall in the provinces of Burgos, León, Palencia and Soria. And yet, AEMET has not issued a red weather warning. What is happening here? QTo start: everything is working normally. And we must not forget that AEMET and Civil Protection do not do the same work. The State Meteorological Agency is limited to issuing weather warnings that are based on physical and objective thresholds. Civil Protection, on the other hand, declares the alert based on the expected impact (on the population and/or infrastructure). In this sense, they are not things that can be linked directly. And what is happening these days is a textbook example. AEMET has not activated red warnings, simply because snowfall exceeding the highest thresholds is not expected. Yes, the snow level had dropped a lot… but in reality, no one expected a lot of snow to fall. This does not mean, as is evident, that it is not an important episode; Only it is not an extreme episode in purely meteorological terms. In social terms, it is different. Because as Víctor Gonzalez explained There are a series of factors that make this relatively small winter storm something to take into account. To begin with, it is the first episode of snowfall at low levels of the season. As with heat waves in summer, the first ‘episodes’ are always more dangerous because they ‘catch’ the population unprepared. Especially when (as is happening now) that episode comes earlier than usual, when winter hasn’t even started yet. In addition, it coincides with very busy days (because we are talking about a very busy weekend). An important lesson: When we talk about meteorology, it doesn’t just matter how much snow falls, how hot it is going to be, or how much water a storm will dump. What really matters is when, where and on whom it falls. As Víctor González said“If this same episode occurred on a Tuesday in February, perhaps the alert would not have been declared.” Image | ECMWF | Alev Takil In Xataka | AEMET is clear about what we can expect from the polar storm that threatens Spain: the question is whether we are prepared

Gemini 3 promises more quality and precision than ever in its responses. The question is whether we will really notice the difference

by

Google has announced the launch of Gemini 3its new artificial intelligence model. in the company They claim it is their most advanced reasoning model because it is “designed to understand depth and nuance.” Gemini 3 will also be available as standard as part of AI Mode in the renewed Google search engine (in this case and for the moment, only in the US). It is the first time that Google offers the benefits of its AI model from day one in the search engine, but it also reaches the Gemini app and the developers who work with AI Studio and Vertex AI. Behind him success of Gemini 2.5 Pro and Flashthe new version arrives in 30 new languages, including Catalan, Basque and Galicianand as we say you can start testing today in the United States… or outside of there via a VPN. Gemini 3 promises. At least in the tests Google highlights how the model’s behavior has been outstanding in various synthetic tests. Thus, Gemini 3 leads the LMArena classification with 1,501 points—the first to overcome the 1,500-point barrier. According to Google, the Gemini 3’s test results put it ahead of all its competitors in virtually all scenarios. In fact, he manages to reason “at the level of a PhD” according to the tests of Humanity’s Last Exam (exceeds 37.5% of the test without tools) and GPQA Diamond (91.9%). It also makes spectacular progress in mathematics, as demonstrated by the 23.4% on the MathArena Apex test: GPT 5.1 scores 1.0% and Claude Sonnet 4.5 1.6% on the same test, for example. The model also wants to be more direct: his answers are more “concise (…) and he prefers to offer valuable information instead of resorting to clichés and flattery. Tells you what you need to hear, not just what you want to hear“. Gemini 3’s ‘Deep Think’ mode goes even further in tests: in Humanity’s Last Exam it achieves 41.0%, but it also in the demanding ARC-AGI 2 It achieves 45.1% (with code execution), which also demonstrates progress in abstract reasoning and visual understanding. Gemini 3 explains the world to you in a simple way The model has a context window of up to one million tokens, which allows it to be used, for example, to analyze huge repositories of code or text and then work on that data. Its multimodal support allows you to analyze all types of information. For example, Gemini 3 can decipher and translate handwritten recipes in different languages ​​to create a family cookbook that you can share. Or analyze your pickleball games (we assume the same thing happens in other sports) and identify areas where you can improve and generate a training plan. Or scrutinize the data from a research paper and from it generate code for an interactive guide that helps us better understand those studies. In fact, integration with Google Search is an especially important part of Gemini 3, which being “embedded” in AI Mode It has the capacity to generate interactive visual elements (widgets, calculators, simulations) in real time. At Google they want the search to be more interactive than ever, and that will mean that sometimes the answers will not be just text, but rather a small interactive webapp that allows us to better understand the answer. Programming (and agents) to power The other crucial element of the model is its capacity in the area of ​​programming. Its results in tests of this type are once again outstanding, and for example it tops the WebDev Arena leaderboard with a score of 1,487 ELO. The model now behaves much more powerfully in the visual part. It also scores 54.2% on Terminal-Bench 2.0, which evaluates a model’s ability to use tools and operate a computer through a terminal. Additionally, it far outperforms 2.5 Pro in SWE-bench Verified (76.2%), a benchmark test that measures the effectiveness of scheduling agents. These Gemini 3 programming capabilities are intended to be used in a new agent development platform called Google Antigravity. The developer experience is using a “conventional” AI integrated development environment (IDE), but your agents can have access to the editor, terminal, and browser. That means these agents can autonomously plan and execute complex software tasks and validate their own code, making it easier for human developers to review and audit that code than ever before. The real challenge of the most recent models On paper Gemini 3 is postulated as a model that can really make a difference compared to its competitors. The test results and Gemini’s own trajectory make us think that the behavior of this model will indeed be remarkable. However The question is whether we will really notice the difference. In recent months we have seen how other AI companies have launched new models, but the impact for a large majority of users has been discreet: the previous models already performed really well, and although the new ones undoubtedly provide improvements, for many consultations these improvements allow us to perceive that jump in performance. Here we see two ways for Google to effectively demonstrate the capabilities of these models. The first opportunity for Gemini 3 will likely be in the area of ​​programming, and it will be these professionals who will likely be able to get the most out of those additional capabilities. But for the rest of the users, it will be that new AI Mode and the Gemini app that will have to make us notice those features. We are intrigued by this ability to respond with small interactive elements —graphics, widgets—, and perhaps with them we will really discover this new capacity of this chatbot. In Xataka | Let’s say goodbye to Google Assistant a decade later. Google has begun to delete its code to leave only one option: Gemini

The week starts with rains in Galicia. It is just the beginning of a change in the pattern throughout and we are going to notice it

by

We have had a truce, but we already knew that: The first half of November was going to be mild, with some rain and occasional thermal drops. And, generally speaking, that’s how it has been. Now the good thing began. And “good” right now means “rain.” Specifically, as we speak, a very active Atlantic storm (which, if all goes according to plan, will probably be named ‘Claudia’) is opening a corridor of southerly winds that will bring heavy rain in the west of the peninsula, an unusual warm advection for the month of November and, incidentally, a more than considerable episode of haze. The worst part, however, will be the Canary Islands. Are we facing the third named storm of the season? Well, as I say, everything seems to indicate yes. But it is still too early to take it for granted: the peak will be between Wednesday and Thursday, to progress in the coming days in the form of fronts. What happens is that the low will suffer the ‘push’ of a warm flow from the south that will raise temperatures and introduce a stream of Saharan dust in the country. Why is this important? In Galicia and the Canary Islands it is important because almost 200 liters per square meter can fall. And, in some areas, the problems can be enormous. However, it is something that also matters for the rest of the country. And not only because the strong winds and rains can affect large areas of the northern half of the Peninsula. Above all, because it is an example of what is going to be one of the great challenges facing meteorology in the coming years: deciding what is a problem. When should a storm have a name? A few days ago, while a storm with subtropical characteristics It caused problems (many problems) In Huelva and Seville, meteorologists discussed whether that storm should have been named. In the end, the official list of named storms seeks to improve public perception and response; and that is not something as easy as giving a name when the notices go from orange to red. What we are going to see these days is something relatively common: omega blocks, undulating jets, storm trains and atmospheric rivers. The only new thing is that They are going to grow, they are going to get stronger and they are going to do it little by little. Almost imperceptibly. What is going to happen this week is a warning to sailors: it is a trailer of the future we are going into.
