how long it usually takes for your 2026 return and what they can review if it takes them long

by

Let’s tell you When are they going to pay you the refund? of Income 2025, which is what we do in 2026 to catch up on the last fiscal year. According to the Income calendarthe period to submit the declaration ends at the end of June, but if you have already done it and you get a refund, it is normal that the Treasury has already paid you. The in-person declaration It started in June, so it is normal that returns are not being made yet. But if you have made the rent online either by phone In the past few months, perhaps you should have received it by now. Therefore, we are going to try to clarify the times for you. How long does the Treasury take to pay? The normal thing is that the Treasury takes a little time to pay you once you present a tax return that you have to return. In fact, it could be a week or two if everything goes well and they haven’t detected anything. However, there are times when Payment may be extended due to additional checks what the tax agency has to do. In these cases, the Treasury has a period of six months since the declarations end on June 30. In other words, returns can be extended until the end of the year. There are some factors that can accelerate the process. For example, submit the declaration as soon as possible, since they are usually processed in order. Also confirm the draft without changes, although you should ALWAYS review it to avoid errors. And if you attach your correct bank details with an account in your name, delays due to verification are also avoided. Why it may take them a while to get your money back If you detect that your return has been returned, but several weeks have passed and the Treasury has not yet made the payment, it may be because They are reviewing some points of the declaration or making some checks on aspects that are not clear. To find out if the delay is due to this, you can check the status of your declaration from the web or from the mobile app. If the status shows that it is under verificationthis means that the delay is effectively due to the fact that they are carefully reviewing the information you have submitted, and that is why the return is being delayed. One thing you should know is that when the Treasury starts to look at something closely, You may receive a request for information. This will be a postal letter that will arrive asking you to provide invoices for deducted expenses, tax certificates, money movement information, or whatever they consider necessary. These are the main reasons why the Treasury may be reviewing your data and sending you a request: Deductions: There are a large number of income deductions through which you can save money on your tax return, from renovating your car to buying a car or spending money on glasses. But there are some that vary depending on the autonomous community, and if you have deducted something in the declaration that does not correspond or something for which you have not provided the necessary information, they will require invoices or more information to verify it. Housing rental. When you rent a home you have income that is not billed as such, so at the beginning of the rental you may be asked for the contract and payment receipts so that the deduction can be applied correctly. It will be verified that everything is as indicated on the papers. Cryptocurrencies. The Tax Agency increasingly checks the movements you can make with cryptocurrencies, and it is very important that you declare them properly in your Income Tax to know the benefits you may have had with them and that the corresponding percentage of Personal Income Tax is applied to you. Debts with the administration: On some occasions, even if the declaration is correct, the return may also be delayed in the event that you have a debt with the Treasury, Social Security, your town hall or even unpaid fines with the DGT. If so, these will be deducted from your deduction. If any of these cases occur, the Tax Agency officials will take extra time to check your data, and will send you a request to ask for additional information if they see it necessary. The Treasury has until December 31, 2026 to make returns, so they may take it easy. In Xataka Basics | Income Guide 2025: calendar, previous steps and how to prepare for the 2026 declaration

Bad Bunny’s authentic party takes place in Sector T, the “stiffs” outside the Metropolitano

by

600,000 tickets are a lot of tickets. They are the ones that Bad Bunny has sold out for twelve concerts in Spain. The cheapest ones are around 70 euros. The most expensive, 600. The venues are going to be full every night. And yet, hundreds of people stand on the street, spread blankets and take out refrigerators around Gate 20 of the Riyadh Air Metropolitano and listen to the concert with a clarity that rivals that inside the venue. They call themselves Sector T. The T is for “stiff.” Who are they? Bad Bunny’s second concert in Madrid On Sunday, June 1, it left in its wake, along with the inevitable celebrity counts at the Casita (which are invariably the most read news in the media that cover the concerts), an image that circulated on social networks: hundreds of people who did not get (or did not want) entry gathered spontaneously outside the stadium, specifically in the area of ​​gate 20. There the music comes with surprising clarity and you can even see part of the stands of the venue. The scene was summed up by a spectator with a phrase that accompanies many of the videos: “Sector T of stiff but happy being able to afford the 10 dates.” The expectation. Bad Bunny debuts in Madrid a residency format that he had only done before in Puerto Ricowith ten consecutive nights in the same stadium. The tour brings together more than half a million people in its ten dates at the Metropolitano, with tickets flying in a matter of hours after they went on sale. The demand was so brutal that thousands of fans were unable to attend, but the feeling has not diminished that the concert is the place in Madrid where you “have to be” right now (with permission of the Pope’s visit). That is why the T Sector phenomenon has occurred. Metropolitan FTW. The Atlético stadium was not always the first reference in terms of concert venues in Madrid. That role corresponded to the Bernabéu, whose expensive renovation was designed precisely to turn it into a continuous entertainment space, without depending on football. We already know the story: acoustic problems, complaints from neighbors, and now the developers have to take care of possible fines. Clearest consequence: the Metropolitan takes the biggest musical shows of the yearamong them Bad Bunny and his ten nights at the athletic stadium. The Metropolitano has established a contractual limitation that requires all shows to end no later than 10:59 p.m., as a measure aimed at protecting residents’ rest and bringing forward the departure of the public. The venue also states that it operates with one of the most advanced acoustic control systems in Spain, which includes real-time monitoring, limiters verified by the City Council, probes in homes in Canillejas and Las Rosas and state-of-the-art acoustic barriers. Neighborhood associations have complaintsYes, because of the chaos at the exit, with traffic jams, horns, screams and so on. Sector T, of course, is a free agent who is not subject to any of those restrictions. The future of the T Sector. Bad Bunny still has eight more dates confirmed at the Metropolitano: June 2, 3, 6, 7, 10, 11, 14 and 15. The makeshift sector of Gate 20 will have the opportunity to grow over the next two weeks: Sector T will grow larger as the tour progresses and images of the exterior circulate alongside those of the interior. What is not yet clear is whether the Metropolitan or the organization of the event will take any measure regarding the concentrations at the exterior entrances. For now, no one has told them to leave, so they will be there. And some will repeat.

The AVE to Extremadura has taken a key step in its connection with Madrid. It’s a small step that takes us back a decade.

by

They say that things in the palace go slowly. We could say the same about high speed. Not only because “high-speed” trains are taking longer than ever, but also because the construction of each new line resembles a birth that lasts decades. For example, the AVE to Extremadura. A quarter of a century has now passed since the project was approved. 25 years. And what we continue to have are connections typical of the 70s until we enter Extremadura where, coincidentally, the pace is already accelerating past Cáceres. We don’t lie. In 1970whoever took a train to Extremadura would arrive at the current Monfragüe station in 181 minutes. Today if everything goes well it will only take 20 minutes less. More than half a century after passing times collected in this guideit still takes more than three hours to get from Madrid to Plasencia. And right now it is necessary to stop at the aforementioned station and take a bus because the train no longer goes there. At least, in Extremadura they can boast since last December of having Cáceres and Badajoz connected, now, by high speed. Since the last days of the year, it is possible to cover the journey in 50 minutes. It is the result of works that, although they have taken time, have ended up being completed. A milestone that they cannot boast of in Castilla-La Mancha. And, 25 years after beginning to study where the AVE will pass on its way to Lisbon, a new step forward has been taken. One that also takes us almost ten years back. One step forward, Toledo. One step back When it was planned that an AVE would connect Madrid with Extremadura, it was decided that the work would have two large, clearly differentiated sections. One of them would be Madrid-Oropesa, the second Talayuela-Cáceres. With its obvious delaysthat second section is close to completion and its completion past Cáceres is what has allowed the arrival of high speed in that interprovincial Extremaduran section. And, as they point out in this great review of the diary Today Despite all the dates that have occurred in this quarter of a century, the end of the project could have been very advanced if the La Mancha section had been built at the same speed. However, since 2008 the various parties involved have been discussing what to do with the passage through Toledo. Or, rather, whether or not the train should pass through Toledo. That year, with the environmental impact report of the Madrid-Oropesa section already approved, the final approval was given to the informative study that contemplated a connection with the Andalusian corridor next to the Toledo town of Pantoja. The idea was to take a branch of this line towards Extremadura and thus save costs. The works, however, were not carried out. The 2008 crisis wiped out the project and it was never launched. Without machines working, the environmental report expired and that was when the Ministry of Public Works indicated that the AVE would pass through Toledo. We are already in 2017. The Government’s proposal was that, by passing through Toledo, the line would attract a greater number of travelers since the line would connect with a city that is a World Heritage Site. Of course, this meant traveling more kilometers and increasing travel time because Toledo is located further south than the first proposal. The idea was rejected by local authorities from the first moment. And the passage through Toledo It’s delicate. The Executive’s proposal has always been to take the AVE to the current station, which is just two kilometers in a straight line from the city center. But that means building a viaduct to overcome the passage of the Tagus, which has received continued rejection from local governments and the neighborhood platforms that consider that the image of the city would be damaged. Their proposal was to build a new station in a nearby industrial estate. This is how the year 2020 was reached, with an informative study in which it was proposed to subdivide the section into four parts: Toledo, Torrijos, Talavera de la Reina and Oropesa. They also showed their rejection of this project in Torrijos, which led to more bureaucracy and carrying out a complementary study in 2022. This document was presented in 2024 and had the approval of this town the following year… but in Toledo, as we have said, they still do not view the project favorably. In order to streamline the project, finally The Ministry of Transport has finally approved a new informative study that would contemplate building two branches from the Andalusian corridor. They explain in Today that if the branch goes ahead it would have its origin in Pantoja (as planned from 2008 to 2017) and that it would allow passage in both directions with trains of Iberian width and international width. However, it would be necessary to use trains capable of making this jumpsince the rest of the route to Extremadura is built on Iberian gauge. That is, right now what is being studied is the same to the conclusion that It was arrived in 2008 and that remained on the agenda until 2017. At least, as an alternative until it is decided whether or not the AVE to Extremadura passes through Toledo. And, if it happens, where is it going to do it.

Vigo already has its “direct” AVE to Madrid without stops in Castilla y León. Now it takes longer than before

by

A little over a year ago, controversy arose between autonomous communities. Abel Caballero, mayor of Vigo, claimed that one of the reasons why the AVE to Madrid did not take the promised time was due to “an excessive number of stops in the Castilla y León area.” The response was not long in coming. Now, the people of Vigo have their “direct” train to Madrid, without stops in this autonomous community. The problem: they come out earlier and take longer than before. 215 minutes. That is the promise with which the railway link between Vigo and Madrid was announced. Yes, you read correctly: three hours and 35 minutes. Since high speed was launched in this corridor, the trains that have approached the promise that Óscar Puente put on the table in 2024 have been an exception. Instead, the trains have taken at least four hours. In the best of cases, barely a minute has been cut from the journey, but in practice they continue to move on the psychological border of 240 minutes. As long as there is no delay. And in the Galician corridor they know well what we are talking about. Too many stops. Given the impossibility of fulfilling that promise, Abel Caballero, mayor of Vigo, proposed a simple formula: that the trains not stop in Castilla y León. He did not say anything about Galicia because, in his opinion, it was the arrests in the neighboring autonomous community where the most time was wasted. “The current travel time on some of the routes is very long due to an excessive number of stops in the area of ​​Castilla y León, an area already close to Madrid that currently has a very important coverage of trains coming from all over the north and the rest of Galicia on high-speed routes” The words were picked up in the local media Atlantic.net and, according to Caballero, they were well received by Álvaro Fernández Heredia, president of Renfe since where they quickly denied this possibility. The proposal collided head-on with Alfonso Fernández Mañueco, president of Castilla-León, who in words reported by The Spanish He described Caballero’s words as “intolerable.” Vigo-Madrid route starting May 20 “Straight”. So, in quotes. Because starting May 20, Renfe will have an AVE without stops between Vigo and Madrid. The long-awaited Galician demand has been heard. As you see in the image above, from that day on the train from Vigo will leave at 5:50 a.m. and arrive in Madrid at 9:55 a.m. Once it leaves Vigo, the train will stop only in Galician cities. Once we have passed Ourense, the train will not stop until it reaches the Chamartín station in Madrid. It is, finally, the “direct” AVE that the people of Vigo demanded to be able to travel back and forth to Madrid in the shortest time possible. Vigo-Madrid route until May 19 Sure? And, contrary to what logic says, Vigo-Madrid takes longer than before. And, in addition, it will force passengers to get up earlier. And until that day, the first train that connects Vigo with the capital will continue to stop in Zamora but its journey will take eight minutes less. In addition, it leaves at 6:00 a.m., instead of 5:50 a.m. The reason is that, with the reorganization devised by Renfe, the first train has to stop in Santiago de Compostela, which has been omitted until now. And the residents of Ourense do not see a great reduction in times either, since it will only take four minutes less to reach Madrid despite not stopping in the Castilian-Leonese city. To make matters worse, the residents of Pontevedra will not find a substantial advantage either. In fact, they will now take eight minutes longer than before the last change. Now, with the latest changes, all trains leaving in Vigo and arriving in Madrid will take more than four hours. Adif, in the spotlight. Part of these “delays”, they point out from Vigo Lighthouseare due to the works that are being carried out in the Guadarrama tunnel at the entrance to Madrid. These add seven minutes to the final amount but as they point out from The Region There are numerous temporary speed limitations on the Galician section that hinder the promises of connecting Vigo and Madrid in half an hour less. He Vigo Lighthouse He also points out that Renfe has been complaining for some time about Adif’s management of the roads. According to the Galician media, the operator has requested on several occasions that some crossings between trains be relocated so that they are not on the single track sections. And the passage times have not been updated either, so, they point out, the current speed cannot be increased either. An exception. Since the Galician high-speed corridor began to operate at full capacity thanks to the use of the Talgo Avril that can change track gauge, doubts about the reliability and performance of these trains have been on the table. First for its disastrous arrivalthen for their problems with the change of year in 2025 and finally due to the cracks that appeared in these trains on the Madrid-Barcelona. However, the trains have proven capable of operating at full capacity and getting closer to the famous 215 minutes promised between Vigo and Madrid. Last November, A Renfe AVE managed to cover the journey in 217 minutes. The problem is that it only served to alleviate the delay accumulated at the origin. Being the last service and with the tracks already clear along the entire route, the Avril was able to travel at maximum speed for as long as possible.

Colombia was considering sacrificing Pablo Escobar’s 80 hippos. An Indian billionaire has said he takes them

by

There is a story that seems taken from a García Márquez novel but is completely real: in Colombia they live, free and in the middle of nature, more than 160 hippos. It’s not that evolution brought them to that corner of the world. In fact, they shouldn’t even be there, but they have been one of the largest for decades. environmental headaches of the country. The origin of everything is in the exotic whim of drug trafficker Pablo Escobar. The sacrifice. What began as a millionaire’s extravagance has become a serious problem since it is an invasive species weighing 4,500 kilos and without local predators. Colombia has not found a solution for the new river “squatters” for years, but has decided take drastic measures against the uncontrolled growth of hippos thousands of kilometers from their place of origin: sacrifice half the population current hippopotamus. However, just when the government was about to implement its plan, another millionaire has taken matters into his own hands and offered to take 80 of these animals to a sanctuary in India. What is a hippopotamus doing in Colombia? In the 1980s, the leader of the Medellín cartel, Pablo Escobar, bought four hippos (one male and three females) from a US zoo to incorporate them into the private zoo that was being set up at Hacienda Nápoles, his immense estate in Colombia. After the drug kingpin’s death in 1993, no one knew what to do with them. Moving animals that do not have a reputation for being very sociable and weighing up to 4,500 kilos each, was not a simple task. Given the apathy of the local authorities and the abandonment of the drug lord’s residence, the four animals escaped and entered in the Magdalena River basinwhere they found their new home in freedom. In fact, they acclimatized so well that today, almost 40 years after their arrival in Colombia, they still they coexist without control with endemic species that are not prepared for their presence. A population that does not stop growing. The problem with having adapted so well to life in the wild is that what started with just four hippos has gotten out of control. Without natural predators, their reproduction has skyrocketed. According to a published study In the Magazine of the Colombian Academy of Exact, Physical and Natural Sciences in 2024, the population grows at a rate of between 8% and 9% annually. Today it is estimated that there is a population of between 169 and 181 hippos distributed in up to seven groups in Colombia and is calculated that, without human intervention, by 2040 they could exceed 1,500 specimens if no measures are taken. They have found paradise for hippos. Colombia offers hippos something that is scarce in Africa: stability in the levels of its river channels. In the Magdalena River basin there is enough water even in times of drought, so the plump animals can do what they like most all year round: spend about 20 hours a day submerged. In addition, the river banks provide them with up to 35 kilos of grass daily. It is the closest to paradise this species has found. But it’s not his place. An ecological problem of the first magnitude. What worries authorities and conservationists the most is not only the growing number of hippos in the waters of the Magdalena, but the impact that this invasive species is generating in that ecosystem and in the native species. Colombia is home to practically 10% of the planet’s biodiversity and, according to a study from the University of California at San Diego (UCSD) published in the scientific journal Ecologyhippos are endangering the survival of manatees, otters, capybaras and fish endemic to the Magdalena. Given the weight, volume and appetite of these animals, the structure of the land is being altered and their feces in the water trigger a eutrophication process which favors the proliferation of algae harmful to river fauna. Colombia declared them officially invasive species in 2022, with all the attempts to control its population through chemical sterilization and castration. Desperate not to find a solution to the largest invasive species on the planet, in April 2026, the government announced that it would include the sacrifice of specimens among its measures, generating an intense international ethical debate. Anant Ambani’s offer. That’s where Anant Ambani, son of Mukesh Ambani, the richest man in Asia, also known for celebrate a wedding in 2024 which cost around 600 million dollars. Ambani is also an activist for animal protection and founded Vantaraa sanctuary in Gujarat (India) that houses hundreds of rescued species from around the world. Upon hearing the news of the fatal fate of those known as “cocaine hippos“has contacted the Colombian authorities to offer asylum in Vantara to 80 of the hippos destined for sacrifice. The Colombian government has not yet made an official statement, but it is not expected to reject the millionaire’s offer in order to resolve part of its problem with Pablo Escobar’s “pets.” In Xataka | Japan sent the wrong creature to eradicate snakes from an island.

“It takes two years to learn to speak and sixty to learn to be silent”

by

Whether or not you are part of their legion of userssomething must be recognized about X, the old Twitter: it has become a gigantic social laboratory. Also definitive proof that it is often less difficult for people to open their mouths (or type) than to think beforehand about what we are going to use them for. It doesn’t matter that it’s the last game of the League, the war in Iran, a video of kittens or issues as sensitive as euthanasia: There will always be someone willing to take out their phone and share their opinion, even if that opinion has just been formed. Hence in this world verbose Ernest Hemingway resonates strongly: “It takes two years to learn to speak and 60 to learn to be silent.” Speak and be silent. The history of Philosophy (thus, with capital letters) is full of good ideas… and suggestive phrases of uncertain origin and dubious attribution. We have told it more times. A quick Google search arrives to find alleged statements by Marcus Aurelius, Da Vinci or Marie Curie (among a very long list of thinkers) whose authorship is impossible to confirm. Something similar happens with the sentence that concerns us today. We have been putting the phrase “It takes two years to learn to speak and sixty to learn to be silent” on Hemingway’s lips for decades when in reality it is impossible to know if he ever uttered it. In 2019 Quote Researcher tried to confirm it and came to three conclusions. First, it dates back to at least 1909, when Hemingway was still a boy from Illinois. Second, that it has been associated (with variants) with other intellectuals, including Mark Twain either Lydia Allen DeVilbiss. Third, it is very difficult to go beyond the two previous conclusions. The value of each word. In view of all the above, we might ask ourselves why pay attention to a proverb of diffuse authorship. The answer is simple. Perhaps we cannot confirm if it came from Hemmingway’s lips (or pen), but it certainly connects with the style of a novelist who was characterized by concise sentences and maximum economy of language. In the works of Hemingway every word counts. And that is also a valuable lesson if we think about the fact that humanity (or at least a large part of it) has never had it so easy when it comes to expressing its opinions and participating in public debate. The torrent of public opinion is so powerful that it has even overflowed and has been carried forward the 140 characters of Twitter. In defense of silence. If Hemingway’s supposed phrase has been captivating us for more than a century, it is not only because of its ironic point. To a large extent it also connects with an idea that has permeated philosophy since the time of Pythagoras, to whom another similar phrase is attributed: “Listen, you will be wise”. People express themselves naturally. It is part of our elemental baggage, which we develop during the first years of life along with other skills such as walking. The complicated thing, in fact, is to do the opposite: embrace silence. In silence you think, reflect and listen, tasks that often require active effort. “It takes sixty years to learn to be silent,” reminds us Hemingway sarcastically, implying that silence is a complex virtue that we must work on and takes a lifetime to master. Is it that important? Yes. Educated in a world in which from a very young age we are instilled that ‘he who remains silent grants’ it is easy to forget it, but silence is sometimes an art. To begin with, it requires self-control. It is not always easy to remain silent. As they comment our colleagues TrendsIt also requires discipline, tolerance and a certain dose of humility and generosity. Against polarization. In exchange, silence offers us other things. It leaves us more room for reflection, to form more informed opinions and, above all, to measure our words and avoid regrets. In the age of networks, the debate held from anonymity and with society increasingly polarizedalso helps to ask certain questions: Can I contribute something to the conversation? Am I sure of what I’m going to say or will I just contribute to generating noise? What repercussions might what I say have on others? The virtues of silence and contemplation have been defended by many thinkers throughout history, from Pythagoras to the Stoics (including Epictetus either Marcus Aurelius) to the great humanists of the Renaissance. Even neuroscience has endorsed the advantages of giving yourself some time before opening your mouth. I already said it Aristotle himself in another equally ingenious phrase: “The Wise Man never says everything he thinks, but he always thinks everything he says.” Images | Wikipedia 1 and 2 Via | Trends In Xataka | “A place of joy with pain”: the phrase that summarizes the Aztec philosophy to be happier in this life

It takes 7,000 GPUs to simulate a tiny quantum processor. Although it may not seem like it, it is excellent news.

by

The complexity of quantum computers It is extraordinary. In their construction it is possible to rely on several very different strategies, such as, for example, superconducting qubits, ion traps or neutral atoms, among other technologies, but they all have something in common: to a large extent its power is a consequence of its complexity. Of the complexity inherent in any device designed to take advantage the laws of quantum physics. The surprising thing is that, despite its sophistication and exoticism, it is already possible to accurately simulate a small quantum processor using conventional hardware. In fact, has achieved it a research group from the Quantum Systems Accelerator and the Division of Applied Mathematics and Computational Research at the University of California at Berkeley (USA). This is not the first time that a quantum processor has been simulated, but until now no one had managed to do it by emulating every physical detail before its manufacture. A new era begins in quantum chip design Here’s a shocking fact: the Berkeley researchers I mentioned in the previous paragraph have carried out their simulation of a quantum chip using the Perlmutter supercomputer, which contains 7,168 NVIDIA GPUs. To achieve their purpose, they used almost all of these GPUs for 24 uninterrupted hours, so it is evident that the computational effort was titanic. But they got it. They managed to model a multilayer quantum chip 10 mm wide and 0.3 mm thick, accurately simulating how signals travel and interact within this processor. This statement from Andy Nonaka, one of the scientists at the Berkeley Quantum Systems Accelerator, express clearly Why this milestone is so important: “I am not aware of anyone who has ever performed physical modeling of microelectronic circuits at the full scale of the Perlmutter system.” “I’m not aware of anyone having ever done physical modeling of microelectronic circuits at the full scale of the Perlmutter system. We were using almost 7,000 GPUs (…) We divided the chip into 11 billion grid cells and were able to run over a million time steps in seven hours, allowing us to evaluate three circuit configurations in a single day. These simulations would not have been possible in this time frame without the complete system” What really what makes the difference is precision with which they have managed to carry out the design and simulation of their quantum processor. “We perform a full-wave physics-level simulation, which means we care about what material is used in the chip, its design, how the metal is wired (using niobium or other types of metal wires), how the resonators are built, what the size, shape and material used are (…) We care about those physical details and we include them in our model,” Nonaka says. A priori we can conclude that using almost 7,000 GPUs for 24 hours with the computational effort and energy expenditure involved in this process to simulate a quantum chip just 10 mm wide and 0.3 mm thick is not a success. But yes it is. Thanks to this technology, it will now be possible to design quantum hardware in less time and in a more efficient way. Bert de Jong, director of the Berkeley Quantum Systems Accelerator, invites us to look towards the future of quantum computing with optimism: “This unprecedented simulation is a critical step in accelerating the design and development of quantum hardware. More powerful, higher-performance chips will unlock new capabilities for researchers and open new avenues in science” Image | Generated by Xataka with Gemini More information | ScienceDaily In Xataka | We already know what the chips that will arrive until 2039 will be like. The machine that will allow them to be manufactured is close

Artemis II takes off successfully and humanity returns to the Moon after more than 50 years

by

Artemis II It has taken off successfully and we are not facing just any launch. What we have seen marks the return of beings humans heading to the Moon more than half a century after the last missions of the Apollo program, a milestone that for decades seemed reserved for the history books. This time, furthermore, it is not just about returning, but about taking a crew further from Earth than any human being has gone in more than half a century, in a mission designed to validate NASA’s deep exploration system in real conditions. To understand the dimension of this takeoff, it is worth stopping for a moment at what exactly Artemis II is. The mission represents the first crewed flight of NASA’s new exploration system, which combines the Orion spacecraft, the SLS rocket and the Kennedy Space Center’s ground systems. For approximately ten days, the astronauts will evaluate the behavior of the ship in real deep space conditions, something that until now had only been tested without people on board. NASA itself raises it as an essential step to pave the way for future missions designed to return to the lunar surface. The journey that returns humans to the lunar environment Before reaching this moment, what we have had has been a countdown with some tension. In the hours before, the teams had to review an anomaly in a temperature sensor of a battery of the abort system, which NASA attributed to an instrumentation problem and which, according to the agency, would not affect the launch. Added to this was another incident in the flight termination system, the safety mechanism that allows the rocket to be destroyed if it deviates from its trajectory and poses a threat, a problem that placed the mission in “no go.” Both setbacks were left behind before takeoff and are now part of the background of a day that finally went ahead. The planned flight path of Artemis II Over the next few days, what we will see will be a relatively short, but very demanding mission. After launch, the spacecraft will first enter a high orbit around the Earth for about 24 hours to check that all systems are working correctly, before beginning the journey to the Moon. From there, the crew will perform various maneuvers, including a manual control test and approach to the upper stage of the SLS, to validate Orion’s behavior in real situations. The plan is to circle the Moon and return without setting foot on our satelliteon a journey of about ten days designed to rehearse each key phase of the trip. The crew of Artemis II If you look at the crew, What we find is a very measured mix of experience and symbolism. Reid Wiseman is the mission commander, accompanied by Victor Glover as pilot and Christina Koch and Jeremy Hansen as mission specialists, four profiles who have already experienced space first-hand. Together they have accumulated 660 days in orbit and 12 spacewalks, which fits with a mission in which every decision counts. Added to that is something that also weighs: Koch will be the first woman to travel to the Moon and Hansen the first non-American to do so, opening a new stage in who is part of these trips. There is a detail that touches us a little more closely and that we should not lose sight of. Part of this mission also passes through Spainspecifically by Tres Cantos, in Madrid, where Airbus Crisa has designed, manufactured and validated the Thermal Control Unit of the European Service Moduleintegrated into Orion. This system is responsible for supplying air and water to the crew and maintaining the temperature within appropriate levels for both the astronauts and the equipment. It is a discreet piece within the whole, but without it it would not be possible to sustain a mission like this in safe conditions. In development.

How to ask for European aid that almost no one takes advantage of and ends in June 2026

by

There are still a few months left for the stifling heat, but to insulate ourselves from both the cold of winter and the high temperatures of summer, it is vital to have efficient windows. We know it is not a small investment. However, there is a lifeline: an EU-funded Next Generation EU grant program that pays you up to 40% of the bill for changing your old windows. The problem is that perhaps you had not heard about this and the general deadline to execute the works sets a non-negotiable limit of June 30, 2026. What are the conditions? At the state level, aid is framed in the Aid program for actions to improve energy efficiency in homes. As explained by the Ministry of Housing and Urban Agendathe objective is to reactivate rehabilitation in a country where more than 81% of buildings have a poor energy rating (letters E, F or G). The program’s numbers are resounding and go straight to your pocket: The subsidy covers 40% of the cost of the action, with a maximum limit of 3,000 euros per home. The minimum investment must be equal to or greater than 1,000 euros. The requirement is that the home must be the habitual and permanent domicile of the applicant (owner, usufructuary or tenant), which is accredited through the registry. The technical objective is to achieve a reduction of at least 7% in the energy demand for heating and cooling, reduce the consumption of non-renewable primary energy by 30%, or replace elements of the façade in compliance with the Technical Building Code (CTE). The good news is that simply replacing old windows with PVC or aluminum models with thermal break and low-emissivity glass is usually enough to comply with the CTE route without having to undergo a comprehensive renovation. But is it as simple as it seems? Here come the problems. The main obstacle to this aid is purely bureaucratic. The most common and tragic mistake that users make is starting the work blindly. The usual process is usually: the owner calls the installer, changes the windows and, with the work already finished, calls a technician to do the energy certificate, thinking that that is enough. Big mistake. The guidelines are non-negotiable: to justify the subsidy it is mandatory to have an energy efficiency certificate prior to the work and another one afterwards. Both must be signed by a competent technician and carried out with the same official program. Without this documentary demonstration of the “before and after”, help is lost suddenly. The aid map in 2026. The distribution of this program works under the “simple competition” model: whoever arrives first and meets the requirements gets it, until the funds are exhausted. Being managed by the Autonomous Communities, the map is a puzzle. According to the data collected by the regional resolutions, this is the scenario of the main windows that remain open: Aragon: Keep your call active until June 29, 2026but with a specific provision aimed at municipalities of up to 5,000 inhabitants and for buildings prior to the year 2000. Canary Islands: They keep direct aid and tax deductions in force, remembering that the action must be completed before June 30, 2026. Estremadura: They have a specific regional program for rural areas (municipalities with up to 10,000 inhabitants) open from March 1 to June 1, 2026. They cover 50% (extendable to 70% due to vulnerability or young/large families) with limits of up to 14,000 euros for single-family homes. Rioja: Its call opened on February 17 and will last until June 29 2026. Pay attention to the information: here the actions must already be completed at the time of requesting help. The Basque Country: Play in another league. It has its own aid for particular works unrelated to the Next Generation framework, with deadline open until December 31, 2030. For their part, the communities of Andalusia, BalearicsCastilla-La Mancha, Valencian Community, Galicia, Madrid, Murcia and Navarrethe windows are already closed. The perfect move: how to combine aid with personal income tax. For those who arrive on time, the operation is round. According to the Royal Decree-Law Approved by the Government, these direct subsidies are fully compatible with tax deductions in the income tax return (IRPF), valid until December 31, 2026. How does this double advantage work? Imagine that changing the windows costs you 8,000 euros and you receive the maximum subsidy of 3,000 euros. When filing your income tax return, you can apply a deduction (20% or 40%, depending on the energy savings achieved) on the remaining 5,000 euros that you have paid out of pocket. The only legal limit is logical: you cannot deduct from the Treasury the money that Europe has already financed you. From insulation to forced ventilation. Taking advantage of this injection of funds is a golden opportunity, but isolating as much as possible has consequences. By installing ultra-efficient windows, the home becomes so airtight that The regulations already require mechanical ventilation systems to renew the air without losing the accumulated heat. In short, the bureaucracy is clear and the clock is ticking. Changing your windows before the funds run out is not just spending 3,000 euros, it is the definitive step to turn your house into a thermal shelter Image | freepik Xataka | The US has resurrected a part of the Manhattan Project that had been abandoned for decades: purified enriched uranium

OpenAI takes a step back in the AI ​​race to completely recalibrate

by

OpenAI Sora has closed. His generative video AI that he has proudly shown on numerous occasions and which earned him a juicy $1 billion deal with Disney it no longer exists. The news fell like a bomb a few hours ago followed by the withdrawal of that billion-dollar Disney investment. Although there are those who point out that OpenAI is in trouble, those problems are not so much economic as lack of direction, and closing Sora seems only a step backwards in the long-distance race of OpenAI and AI. Go public this year and start harvesting after everything planted. In short. It’s the news of the day. Less than a year and a half after launching it, OpenAI says goodbye to Sora. In his day (February 2024, how time flies) we were amazed at what this generative AI could do. It was just 60 seconds of video and had some huge flaws, but it was one more step in the artificial intelligence race that positioned OpenAI at the forefront of the industry. Then other competing models arrived, culminating with a Seedance 2.0 that has consumed the entire Internet to plagiarize absolutely anything. Like all the others, wow. Issues. But although striking, Sora was a tool that didn’t seem to add up. While other services have integrated their generative AI models within an ecosystem or applications (the aforementioned Seedance 2.0 in suites AI or in the video editor CapCutfor example), Sora was there, away. The aforementioned contract with Disney was worth it, but it did not seem to be part of something larger, of a “creative suite” (if generative AI can be classified as such). He simply existed, and the worst thing was that others were passing him on the right. Eggs in many baskets. It was, in short, another product of an OpenAI that had eggs in many baskets. It was reaching dizzying numbers in different rounds of financing, setting up data centers, buying a lot from NVIDIA (depending a lot on NVIDIA, too) and launching products like crazy. OpenAI wanted to touch all the keys: And there are some other products, as well as a super app to integrate all that that was not being integrated into other sites. The philosophy was simple: if we are in everything, something will work, but the result has been the opposite and, as my colleague Javier Pastor said a few days ago, wanting to be the bride at the wedding and the dead man at the funeral It is having consequences. The competition tightens. While OpenAI diversified and allocated resources to touch all suits, Anthropic (which is not just a rival, it is a public enemy) was dedicated to two things. It’s not that Anthropic doesn’t have a browser or a video generator: it’s that they don’t even have an image generator. In exchange, what they do have They are functional, precise models and that they do things very well, especially in the field of amateur development with the vibe coding. Focusing on one thing and doing it very well is something that the market is seeing valueto the point that Anthropic is raising a lot of money in different recent financing rounds. In a short time, it has gone from being valued at 183,000 million to arrive up to 380,000 million, and that has had all the fuss with the United States government and the loss of contract with the Department of Defense. Money, too. And money moves everything, and while ChatGPT sweeps the consumer segment with more than 2.5 billion daily queries, you have to wonder how many paying users there are. Where the money really is, which is in business use, Anthropic controls the market with 32% compared to OpenAI’s 25%. And in programming, the distance is astronomical: 42% compared to 21%. In fact, OpenAI has seen how your business share has fallen from 50% in 2023 to just 25% today. As we say, this is where the greatest potential for growth and commercial performance is, and OpenAI is realizing that being focused on so many fields has caused them to be distracted. Or what is the same: they have covered more than they could bite off. Public company. The closure of Sora responds to a multitude of factors, but in the background there is something more important. NVIDIA has already said that the millionaire mega-rounds are overand it has done so just before the expected IPO of both OpenAI and Anthropic. When both go on the stock market, they will have to face another financing model. They will need products that generate profits to attract investors to buy shares, and right now, the one that is best positioned is Anthropic. OpenAI has a lot, but nothing makes it complete. Anthropic has less, but it is very efficient, and getting rid of Sora seems like a move to release ballast before becoming a “public” company (in the American concept). They have to focus their shooting, focus their teams (something they themselves have recognized) and stop wanting to be too much at once without having a clear strategy. Because they are becoming another example of being a pioneer It doesn’t always mean you’re the best. and that, if you don’t get your act together, competitors who have a clearer roadmap will eat your toast. Only time will tell if the strategy works, but at the rate things are going, it won’t take too long to find out. In Xataka | The worrying thing is not that AI is going to take your job in the future: it’s that it is preventing you from finding one now
