We have been cooling homes for decades with increasingly expensive machines. The Persian method has not consumed a single watt for 2,500 years

July 10, 2026 by usatoday24

For decades, air conditioning has been the great response to heat. The more the temperatures rose, the more powerful the machine we installed was. However, more than 2,500 years ago, in a city in the Iranian desert, someone proposed an idea completely different: Maybe the problem was not how to cool a house, but how to build it so that it never got too hot. The heat has a new enemy. The planet is going through an escalation of unprecedented temperatures and the buildings are starting to pay the bill. Glass facades turn offices and homes into veritable greenhouses, concrete accumulates heat for hours and cities radiate energy at night. absorbed during the day. The consequence is an increasing dependence on air conditioning. According to the United Nations Environment Programme, cooling systems already consume about 20% of all the world’s electricity, a figure that will continue to grow as heat waves become more frequent. The Persian redesign. In the heart of the Iranian plateau is Yazda city where summer temperatures easily exceed 40 ºC and where survival was never a question of comfort, but engineering. There appeared one of the most sophisticated passive cooling systems ever conceived: he badgirknown as a wind catcher. His approach was radically different from the current one. Instead of combating the heat once it had entered the house, the architecture itself took care of it. to capture the fresh airexpel the heat and maintain a habitable interior without consuming electricity. Yazd The “Persian method”: a way of thinking. At first glance, a badgir It looks like a tall, decorative chimney jutting out from the rooftops. In reality, it is a carefully calculated system to take advantage of two natural phenomena. On the one hand, it captures the air currents that circulate several meters above the ground and channels them towards the interior. On the other hand, even when the wind hardly blows, it acts as a solar chimney: Hot air rises through the tower and, as it escapes, creates a depression that draws cooler air into the building. In many homes, this flow also passed over underground water tanks or connected channels. to the qanatsfurther increasing the cooling effect. A bâdgir in Yazd A city designed for the climate. The truly extraordinary thing about Yazd is that the badgir It did not work in isolation. It was part of an architectural ecosystem where each element fulfilled a function. The thick adobe walls slowly absorbed the heat. The inner courtyards they created microclimates protected from the sun. The qanats They transported groundwater from the mountains and helped cool the air. There were even the yakhchalenormous structures capable of manufacturing and preserving ice for months in the middle of the desert. The result was a city designed to work with the climate, not against it. Yakhchal in Yazd And the air conditioning arrived. During the 20th century, much of the Middle East and other warm regions embraced imported architectural models that had little to do with their climatic conditions. Concrete replaced adobe, glass facades replaced solid walls and passive solutions were giving way. to mechanical systems. Many badgir they were abandoned due to the lack of maintenance, due to the entry of dust or insects and, above all, because the air conditioning offered an immediate response. The problem is that it also moved energy consumption to the center of the equation and made cooling a permanent necessity. The irony of the West. As many wind towers fell into disuse in Iran, their principles were beginning to reappear discreetly in other parts of the world. Between the end of the seventies and the mid-nineties, thousands of modern versions of wind sensors in British public buildings. Shopping centers, hospitals and schools incorporated ventilation systems inspired by those ancient designs. In the United States, the Zion National Park visitor center was able to drastically reduce the need for air conditioning thanks to passive cooling strategies based on the same concept. Today architects and engineers they resort to simulations by computer to optimize a technology that was born centuries ago simply by observing how the wind moved. The future may not be in more efficient machines. Contemporary architecture begins to take on an idea that for decades was relegated to the background: the building is also part of the air conditioning system. Recent regulations in countries like uk They prioritize shade, natural ventilation and reduction of solar gain before resorting to mechanical solutions. Exterior blinds, slats, vegetal covers, materials with high thermal inertia or patios return to gain prominence. Even those who defend the use of air conditioning agree that these measures can significantly reduce energy consumption. The big lesson: don’t repeat the same mistake. The history of the Persian method and its badgir It does not prove that we should give up air conditioning. prove something much more uncomfortable: For decades we have tried to solve heat by adding machines to buildings that, in many cases, were designed as if the climate did not matter. The Persians followed the opposite way more than two millennia ago. Before thinking about how to cool a house, they thought about how to build one that needed to be cooled as little as possible. Perhaps the most revolutionary technology to face the next heat waves is not a new machine, but recover an old idea that had been waiting for centuries on the rooftops of the desert.

NASA has managed to make a satellite “understand” what it sees, without sending a single photo to Earth

July 3, 2026 by usatoday24

The role of satellites is simple. They take data, send it to Earth and, once here, it is analyzed. So far, that is being viable. However, the process is getting complicated. There are more and more satellites (Hello, Elon Musk), which means more information flowing to Earth. There are not enough people, energy or time to analyze so much information. For this reason, NASA and the startup LoftOrbital have developed NAVI-Orbital, software for satellite observation that is capable of describing what it sees and even searching for what it is ordered to do. A model of vision and language. NAVI-Orbital works with Gemma 3a series of vision and language models belonging to Google DeepMind. As their name suggests, they are capable of processing both images and text, so that, with proper training, they can describe images and respond to simple text commands. Before, a multitude of complex computer commands had to be used for a satellite to follow orders and even then the results had to be analyzed by humans. Now, all you have to do is ask him to obey and analyze the results. Find what you ask for. A clear example of what NAVI-Orbital can do is search for objects, buildings or geographical features. If you know what a river is, you can search and display all the rivers in a given area. You can also locate all bridges or roads. But, in turn, it can identify anomalies in those places. For example, you may find rivers about to overflow or roads where there has been an accident. much faster. Most artificial intelligence algorithms send information to data centerswhere the result is processed and returned. In this case, however, what is known as edge AI is used. That is to say, the entire model runs directly on the same device that captures the data. The satellite in this case. Civil or military applications. In April, the first tests were carried out with the YAM-9 satellite, which already has the new software incorporated, with very good results. It was the first time that a satellite managed to describe what it “sees.” That’s why NASA and LoftOrbital are already excited about their applications. They consider that satellite constellations with NAVI-Orbital could be used to monitor the planet for civil or defense applications. They can search for oil spills, for example, but also study possible military attacks. The difference with what we have so far with any of these purposes is that nothing has to be analyzed. That is, you don’t put a satellite to take photos of the sea and then here on Earth a team of people or a computer algorithm analyzes them for oil spills. It is the satellite itself that saves sending thousands of photos without spills and directly analyzes what it sees. The result is much faster, cheaper and more efficient. It may even be the future of satellite observation, although it is still too early. We will have to see how these models that have already begun to undergo the first tests evolve.

He was saved by a script that did not admit a single detour

June 27, 2026 by usatoday24

In June 2024, Apple presented one of the most ambitious movements in its recent history: the integration of Apple Intelligence on your devices and, with it, a reinvention of Siri. That keynote promised something that many had been waiting for years: a truly useful assistant, capable of understanding the user contextoffer accurate answers and execute actions taking into account our personal information. Concert tickets, hotel reservations, links shared in Messages or calendar locations: everything would be within reach of the new Siri. The enthusiasm was immediate. Apple presented it as an important transformation and, implicitly, as one of the necessary steps to catch up in the race for artificial intelligence (AI), accelerated after the launch of ChatGPT in November 2022. But the illusion soon evaporated. In March 2025, The company confirmed that the new version of Siri would not be available until 2026and when it did this 2026 we discovered that would not arrive in Europe yet. These two announcements came as a sudden stop. For many, it was not just a disappointment: It was a blow to the credibility that Apple had been cultivating for years. And, despite this, the company did not offer many explanations. The future was simply postponed. We cannot deny that Apple knows how to manage the times. He masters like no one else the art of anticipating what is to come, even when what is apparently presented It’s not quite finished. John Gruber hinted at it.one of the most influential voices in the Apple environment, pointing out that some of the features presented at WWDC 2024 probably did not exist as such. Or, if they did, they were still far from being functional. The secrets behind one of the most epic technology presentations in history And it’s not the first time. In fact, this strategy has a clear precedent, perhaps the most revealing of all: the presentation of the first iPhone in 2007. An event that has become a myth in the history of technological marketing, with Steve Jobs announcing “a revolutionary and magical product.” But what few knew then, and many still ignore today, is that that device barely worked on the day of its debut. Literally. A report from The New York Magazinebased on interviews with former Apple employees, reveals the ins and outs of that historic keynote. Among the testimonies, that of Andy Grignon, senior engineer responsible for the device’s communication modules, stands out. According to him, the iPhone software was plagued with bugs: songs played halfway, videos tended to freeze, and the system could collapse if the tasks were not executed in the precise order. Memory was so limited that just a few simultaneous operations were enough to cause a reboot. Faced with such a scenario, engineers designed an emergency solution: “the golden path.” It was an exact sequence of actions that Jobs had to follow without deviating even a millimeter. Only then could they ensure that the phone did not stop responding during the demo. To cover his back, Jobs would have several identical units on stage. If one was blocked, it would move on to the next without the public noticing. To this technical tension, they explain, was added the aesthetic demand. Jobs did not want a camera pointed at the device to show it on the screen. I wanted one direct projectionclean, without visual interference. To achieve this, engineers incorporated custom boards and video cables that extracted the signal from the iPhone itself and sent it to the projector. It was a fragile and artisanal system, but it did its job: it made everything seem natural, almost magical. The WiFi was another headache. With thousands of people in the room, many with technical knowledge, connectivity could be compromised. To avoid this, Apple modified the AirPort software responsible for connecting the iPhone, adapting it to operate on frequencies reserved for Japan, outside the usual range in the United States. A risky trick, but effective to ensure a stable signal during the presentation. The calls were also carefully prepared. AT&T, then exclusive partner of the iPhone, installed a portable mobile tower to ensure a stable signal. Even so, the demo devices were configured to always display five bars of coverage, regardless of the actual quality of the connection. Against all odds, the presentation was impeccable. Jobs followed the script with surgical precision: he showed music and videos, browsed web pages, sent messages, made a call, explored photos with touch gestures and, in one of the most iconic moments, used Google Maps to locate a Starbucks and order, as a wink, 4,000 coffees. The public surrendered. No one could imagine that that highly advanced iPhone was, at least at that moment, a perfectly rehearsed staging. The level of secrecy was such that, according to The New York Magazine, one of the engineers interviewed stated that some suppliers, such as Marvell Technologies, did not know until the day of the presentation that their WiFi and Bluetooth chips were being used in a mobile phone, and not in an iPod. Apple even designed false schemes to mislead and prevent leaks. We may be, once again, facing one of those stagings that Apple dominates like no one else. The new Siri has already been presentedbut unlike what happened with the iPhone, we keep waiting to be able to use its most ambitious proposal in years. Siri aims to become a transformative tool, but we will have to wait to use it.

ESA has photographed the heart of our galaxy like never before. And he did it in a single day

June 26, 2026 by usatoday24

The center of our Milky Way is something like a sunset at Santorini Castle. Everyone wants to photograph it. Well, in this case, all astronomers. The reason, basically, is that it has a large concentration of stars, so there is a lot of material to dig around and find possible exoplanets. Unfortunately, most of the photos that have been taken so far did not have the ideal resolution for this type of search. However, thanks to the Euclid Telescope, designed by ESA to study dark matter and dark energynow we have the largest and most detailed photo of this point of our galaxy that has ever been done. There is light beyond the darkness. Studying billions of distant galaxies allows Euclid to see how the Universe has expanded and, in the process, determine the possible presence of dark matter. But in this case it has not been used for that. The astronomers have taken advantage their ability to focus on large areas of sky sharply and have taken 9 photographs of regions larger than a full Moon. With all of them they have made a mosaic in which more than 60 million stars, as well as nebulae and star clusters, can be observed more clearly than ever. A catalog of microlenses. The goal of this photograph is to detect gravitational microlensing. These are formed when two stars align in front of an observer (the telescope) in such a way that the gravity of the nearest star bends the light of the one behind it, acting as a kind of magnifying glass. If the nearest star also has a planet orbiting around it, its own gravity also contributes to that process. Therefore, light bends in an asymmetrical way, which serves as an indicator for the search for exoplanets. Logically, to study this phenomenon, catalogs with many stars are needed. Nothing like one this precise. It takes time. It takes at least 20 days to detect such irregularities in the bent light. So a single glimpse of Euclid won’t do that. However, this very precise catalog will be used so that, when launched into space the Nancy Grace Roman telescopethis has a starting point from which to start working. By comparing the same area, not only can microlenses be detected, you can also see how they have varied over time. This makes it possible to detect exoplanets and, by seeing how fast they move, calculate their mass. Previous steps. Catalogs like this have already been made before, although much less precise. In fact, 300 exoplanets have been detected using the microlensing method. The problem is that ground-based telescopes have always been used; which, having the Earth’s atmosphere in the middle, take the images with less sharpness. For example, the telescopes at the Keck Observatory have been widely used. However, what Euclid has photographed in 26 hours would have taken these telescopes more than 2,000 hours of observation. However, Euclid will start from some of those previous steps. For example, thanks to data taken by the Keck observatory and the Hubble Space Telescope (this one is in space, but analyzes smaller areas of sky), it has been possible to calculate the mass of two already known icy exoplanets. The changes in the location of the stars have been seen and the calculations have been made. In summary. Euclid has made the most complete catalog of stars in the center of our galaxy in history. But in reality, their success is largely based on teamwork. A work that is already carried out with the Keck observatory and Hubble, but also with the telescopes that are to come. Especially the Nancy Grace Roman. Image | THAT In Xataka | Caltech has published the “strongest evidence yet” that an unknown planet exists in the solar system

A single programmer, simple mechanics, crappy graphics and Paint interface. And he has earned ten million in a week

June 19, 2026 by usatoday24

Characters that are generic puppets, aseptic to the point of being experimental, elements in the sets that seem to come from a free library for programming learners, an interface that has completely renounced any hint of design or usability and that seems to come from a ‘Paint’ type application… ‘Meccha Chameleon’ has, however, almost ten million dollars earned in one week on Steamand the only reason is not its extremely low price. The milestones. On June 9, Japanese developer lemorion_1224 launched the game on Steam at a price of only $4.99. Today it has sold more than two million units, that is, it has earned about ten million dollars. Discounting the 30% that Valve keeps, the developer has made 6.9 million in less than a week. And it’s all the work of this solo programmer, in approximately two months. How to play. The central mechanic of ‘Meccha Chameleon’ is simple: at the beginning of each round, some players hide and others look for them. The difference with other hide-and-seek games is that hiders can paint themselves to blend in with their surroundings, like chameleons do (sometimes with hilarious results that content creators are fond of). exploiting thoroughly). The more elaborate the camouflage, the harder the player will be to detect. That is, the ability to replicate the pattern of a wallpaper or a painting comes into play. Those less skilled with the brush have another option: look for dark corners of the map where uniform camouflage is sufficient. The precedent. The game collects ideas from ‘Prop Hunt’, a mode that was born in the mythical and highly cult ‘Garry’s Mod’, and that was later incorporated into franchises such as ‘Call of Duty’. The mechanics are the same: some players start as hunters, the chameleons hide, and those who are discovered go to the opposite side. An option can be activated with which those hidden whistle from time to time to give clues about their position. What is original about this new iteration of the idea is the layer of paint that allows for more effective camouflage. But… who is Lemorion_1224? Certainly not a newcomer. This developer had been experimenting for years with hiding mechanics within ‘Fortnite Creative’, the development platform integrated into ‘Fortnite’ that allows you to publish your own modes and accumulate players at no cost. Among these There is a game where players hide by making themselves extremely thin and another where they disguise themselves as NPCs. Lemorion_1224 has also experimented with mechanics inspired by ‘Dead by Daylight’ and ‘Peak’. ‘Meccha Chameleon’ is, therefore, the distillate of several years of testing. Friendslop it. Meccha Chameleon belongs to what in recent years has been called “friendslop”: cheap games, with a very simple, even tacky, visual finish, designed to be played in a group and shared on social networks. That is, games like ‘Peak’, ‘Lethal Company’ or ‘REPO’. The common denominator is the price (below six dollars in most cases), the viral potential and an approach that can be explained in thirty seconds. But to say that ‘Meccha Chameleon’ is part of a viral trend is to understate it: it had a peak of 200,000 simultaneous playerssomething that many AAAs never achieve. ‘Meccha Chameleon’ is another of the very triumphant successes of the medium that reminds us that issues such as graphics or technical neatness are completely accessory aspects to generate fun.

An Air Canada pilot has been flying for 16 years without making a single mistake. And they have arrested him for one detail: he did not have a license

June 12, 2026 by usatoday24

Almost 20 years goes a long way, whether you are an airplane pilot or not. But if you are also one, you will have had time to accumulate almost a thousand international flights, take the controls of different types of aircraft and accumulate good money. It is the summary that Geoffrey Wall could make of his life when, once retired, he told this to his grandchildren or, who knows, told it to all of us in a book. One more story. Tasteless, without substance. But Geoffrey Wall may say otherwise. Yes, you can tell that He flew airplanes for decadeswho took the controls of the best-known commercial airplanes on more than 900 occasions and who accumulated millions of euros taking hundreds of lives from one place to another through the clouds. But he will also be able to tell how he managed to trick his airline into flying planes for 16 years without the relevant license to do so. Everything good, except for one small detail Because the future doesn’t look good for Geoffrey Wall. They count in cnn that the police knocked on his door and he was arrested. The reason: Air Canada notified authorities that one of its pilots was flying with a false license. Not only that, he had been doing it from 2009 until last year. The deception was discovered during a routine check. Nobody had reported irregularities in the controls, no aircraft had been put at risk. But in 2025, during a review of its documentation, it was found that there were some anomalies. By then, the pilot had been flying airplanes within the company for 27 years. However, the company points out that Wall began flying fraudulently starting in 2009. Then, the pilot was promoted to captain and was able to take command of the aircraft and direct operations. The small detail is that he falsified the ATPL-A, the highest level pilot’s license. At a press conference to explain what happened, Deputy Chief Nick Milinovich, of the Peel Regional Police (southern Ontario, Canada), pointed out that “It’s very similar to a doctor who is licensed to practice family medicine but is performing brain surgery in his office.” And he once again emphasized the importance of having the appropriate licenses to perform a job. Especially if in that job you have taken thousands of people through the air. The authorities have explained that the pilot left his job in 2025, just before “Project Icarus”, as the police work has been called internally, started rolling last January. months later They have managed to prove the falsification of the documents and on June 1 they arrested the pilot. However, Air Canada emphasizes that its pilots pass tests regularly and that at no time were passengers put in danger. They emphasize that Geoffrey Wall amply demonstrated his abilities to pilot the Boeing 767, 777 and 787 to which he had access during the last 16 years. During that time it is estimated that Wall earned more than two million dollars with his salary but will now have to face seven criminal charges, including fraud for money earned without a license and falsification of documents. In addition, it has already been fined by Transport Canada, the Canadian Government department in charge of ensuring compliance with all mobility regulations in the country.

We have been mapping Antarctica for decades. We have just discovered that its largest basins form a single tectonic “fan”

June 9, 2026 by usatoday24

For decades, researchers have mapped the frozen continent, finding huge depressions and subglacial lakes that have left us in awe. Until now, these formations were studied as isolated pieces of a geological puzzle; However, a new study has turned this view on its head. The demonstration. This study has been published in Nature Geoscience and has just demonstrated that the great basins of East Antarctica are not independent accidents, but form part of a single, gigantic fan-shaped tectonic province. The tectonic fan. The research team, using a combination of subglacial topography, gravity and magnetism data, proposes that this entire vast region is the result of a distributed rotational extension process. To understand it, we can imagine the Earth’s crust in this area opening and stretching asymmetrically, unfolding as if it were a fan. This colossal tectonic movement makes East Antarctica one of the largest known examples of rotational extension in continental crust on the entire planet. The beginning. The origin of this continental scar is closely linked to the history of our planet, specifically to the tectonic phases linked to the fragmentation of the supercontinent Gondwana and the dramatic separation between Antarctica and Australia. As the land masses separated, the crust stretched and fractured, leaving this “bounced topography” that today lies hidden under miles of ice. Its importance. Beyond the undoubted geological and historical value, understanding this structure has a practical and urgent application, since Antarctica is the great thermostat of the Earth and its stability is key in the face of climate change. The topography beneath the Antarctic ice sheet acts as a mold that conditions absolutely everything that happens on the surface. This is seen, for example, in how the shape of bedrock controls the flow of today’s glaciers and determines how subglacial lake and basin systems are distributed. That is why, if we want to predict with mathematical precision how the Antarctic ice will respond to global warming and how it will flow towards the ocean, we need to know the tectonic “pipe” on which it rests to the millimeter. Its mystery. Although the article Nature Geoscience manages to unify structures as massive as the Wilkes and Aurora basins under the same theoretical framework, the authors maintain scientific caution. The exact age at which this fan province formed and the fine geodynamic mechanism that triggered it remain, to a large extent, open questions, and this means that work still needs to be done to find out exactly when the movements of the Antarctic crust will occur.

Airbus had a single center in the world to convert commercial aircraft into military tankers. Now another one will open in Seville

May 22, 2026 by usatoday24

Airbus has chosen Seville to install its second global conversion center for the A330 MRTT, the best-selling tanker and military transport aircraft on the market outside the United States. The San Pablo plant will thus become the twin of the Getafe plant, until now the only one in the world capable of transforming A330 commercial aircraft into its multirole military version. We made the announcement during the opening of the ADM Sevilla 2026 fair and the facilities are expected to be operational at the end of 2027. Why it matters. The A330 MRTT is experiencing a sweet moment, as it accumulates some 91 orders from 19 countries and controls 90% of the world market share, excluding the United States. The war in ukrainethe escalation of military spending in Europe and the growing need for tanker aircraft to extend the air forces’ operating margin have triggered demand for a model that until now was assembled at a rate limited by its single-plant capacity. Add Seville will allow you to go from five to seven annual conversions and thus take some work off the Getafe plant. In detail. The conversion process is usually a rather complex task for European aerospace engineering. Civilian A330s leave the Toulouse chain and they are transferred to the conversion center, where for about nine months military systems, in-flight refueling equipment, specific avionics, communications and interior configurations adapted to each client are integrated, until they are ready for aerial refueling missions, troop transport, strategic cargo or medical evacuations. The plant in Seville will also assume maintenance, repair and modernization (MRO) tasks for aircraft already in service. Airbus will take advantage of the current hangars in San Pablo and optimize them to work with two aircraft at a time, imitating Getafe’s way of workingwhere usually one is converted while the other receives maintenance tasks. Figures. The new line will generate around 200 direct jobswhich will be added to the 2,000 professionals already working in São Paulo, and about 600 additional positions in the auxiliary industry. In Andalusia, Airbus is responsible for around 3,500 people between the San Pablo, Tablada (Seville) and Cádiz plants, and more than 14,000 throughout Spain. Why Seville. The president of Airbus in Spain, Francisco Javier Sánchez Segura, pointed ABC that the reasons were based above all on the technical knowledge accumulated in the A400M and C295 programs, the existing infrastructure (San Pablo is the only Airbus factory with two final assembly lines) and the operational proximity with Getafe, which will act as strategic coordinator of the entire program. A technological leap. Until now, Airbus Defense and Space’s activity in Seville revolved around the assembly and maintenance of the A400M and the C295, both military transport aircraft. Sanchez Segura underlined The Seville center will replicate the cutting-edge technologies developed in Getafe, including the intensive use of augmented reality applied to the assembly and inspection of systems. Andalusia, in the focus of aviation. For the Junta de Andalucía, the announcement fits into its strategy to place the community in one of the three most important European points, along with Toulouse and Hamburg. The acting Minister of Industry, Jorge Paradela, recalled that the region already has several important investments, such as the arrival of the Swiss company Pilatus to manufacture private and military training aircraft, and the Ryanair projectvalued at 500 million euros, to internalize the repair of aeronautical engines in Andalusia, with 600 direct jobs planned. The acting Minister of Economy, Carolina España, rated the Airbus announcement is “magnificent news”, also highlighting that exports from the Andalusian aerospace sector have grown by 86% so far in 2026. The other side. The ADM Seville fair, where the advertisement was presented, also attracted protests. The STOP Arms Fair Platform, which brings together social groups, unions, environmentalists and pacifists, gathered at the gates of FIBES to denounce “the institutional support” for the defense industry and the presence of companies that, according to these organizations, have links to human rights violations in armed conflicts such as the one in Gaza. What’s coming now. Airbus has about two years of works, personnel training and technological adaptation ahead before San Pablo delivers its first converted aircraft. If the planned pace is met, Seville and Getafe will end up operating in a coordinated manner to satisfy a larger customer base in a context that does not seem to be going to let up. According to Sánchez SeguraAerópolis depends on around 70% of Airbus’ workload, and this for the Seville plant means consolidating in a field that until now was foreign to it.

AtLAST, the telescope that will uncover the “blurred” galaxies in the Universe without spending a single drop of fossil fuels

May 21, 2026 by usatoday24

An international team of scientists, led from Europe, is launching a telescope that will help us see what lies beneath the erased area of the Universe. Ok, no one has erased half of the cosmos, but it is true that a good part of it is covered in a layer of dust so dense that few telescopes can look beneath it. Those who do it, like him Atacama Large Millimeter/submillimeter Array (ALMA)can only focus on a very small portion of the sky. On the other hand, the one presented now, called Atacama Large Aperture Submillimeter Telescope (AtLAST)is capable of looking under dust while acting as a wide angle. All advantages. AtLAST is the result of a project led by Europe, in which Chile, South Africa, Canada, Taiwan, Thailand, New Zealand, Japan and the United States also participate. It consists of a single 50-meter satellite dish and a mirror covered with aluminum panels, as well as a massive steel structure that serves as reinforcement. There is also a 12 meter secondary mirror. It is capable of analyzing very wide regions of the sky and in the process only consumes renewable energy. An attempt has even been made to minimize the carbon footprint in obtaining the aluminum and steel to build the structure. AtLAST vs ALMA. Both AtLAST and ALMA are submillimeter telescopes located in the Atacama desert. This is an ideal place for this type of observations, since it is located at a high altitude, with its telescopes located around 5,000 meters, so that the density of the atmosphere is reduced and does not make observations difficult. In addition, there is no light pollution and it almost never rains, so clouds do not cover the sky either. Until then, everything is fine. The two telescopes are in a privileged location. However, there is something that gives AtLAST many advantages over ALMA. With its 66 antennas, ALMA works as a kind of microscope. It can analyze regions of the sky thousands of times smaller than our Moon. On the other hand, AtLAST, with a single antenna, can see at once the space occupied by 16 moons. Why submillimeter? Submillimeter telescopes are those capable of detecting waves of the electromagnetic spectrum with lengths below a millimeter. This ranges from far infrared to microwave. This makes them the only telescopes capable of clearly seeing what lies beneath the densest layers of dust. Some space telescopes, like James Webbthey can do this to a certain extent. However, this works only from the near-mid infrared. Emissions in the microwave and far infrared range are invisible to him. The secrets of the galaxies. Under those clouds of dust are the stellar nurseries. The gas clouds collapse to give rise to those clusters in which the birth of the star is taking place. Therefore, being able to look clearly down there allows us to analyze the evolution of the Universe in a much more precise way. For example, you can study how it has been expanding and what role dark matter has had in it. You can even investigate how life arises in space. Incredible figures. Other telescopes can detect the light beneath these dust clouds, but they cannot differentiate one galaxy from another. Thanks to AtLAST, however, it is expected to be able to detect up to 50 million galaxies in 1,000 hours of observation. Clean energy. This telescope uses renewable energy, such as solar energy, and stores it in metal hydride batteries. But, in addition, it acts in a similar way to how a hybrid car does. And, after moving to land in different regions of the sky, it loses speed, whose kinetic energy is used to obtain electricity. This way you don’t have to waste fossil fuels. This is just the beginning. It is expected that in the 2040s there will be several such telescopes. This has only just begun. There is still no date for AtLAST to start working, although if everything goes well it is expected to be around the 2030s. Be that as it may, what is clear is that, when it starts working, it will help us reveal the most interesting secrets.

The European Union is very clear about the future of its network infrastructure: there will not be a single Chinese device

Europe is intensifying its battle against Chinese equipment, both in its electrical network and in its telecommunications infrastructure. The European Commission has again recommended earlier this week the exclusion of Huawei and ZTE equipment by local telecommunications operators, paving the way for a review of the Cybersecurity Regulation in which it is proposed mandatory elimination of high-risk suppliers. A new touch. The European Commission has started the week with a reminder: member states must exclude Huawei and ZTE equipment from their telecommunications network. In January of this year, Europe published a draft establishing the mandatory withdrawal of “high-risk suppliers”, posing a formal veto on Chinese telecommunications companies. It is a particularly sensitive issue in Spain, where communities like Catalonia have ignored European recommendations and they have renewed again recently with companies that use Huawei equipment. The Generalitat case. Last March, the Generalitat of Catalonia renewed its contract with XCAT. A budget of 127 million euros to maintain Huawei as the main equipment supplier, despite the EU notice and challenges from Telefónica and Cellnex that paralyzed the process for a few weeks. {“videoId”:”x9gqo70″,”autoplay”:false,”title”:”YOU ARE NOT GETTING THE MOST OUT OF YOUR MOBILE if you are not using AI like this”, “tag”:”Webedia-prod”, “duration”:”617″} In addition to the Catalan case, practically a third of Spanish 5G networks are from Huawei, with an estimated replacement cost between 400 and 1,000 million euros. Beyond. It is not the only measure that Europe wants to implement against Chinese suppliers. The Commission also wants to protect itself in relation to renewable energies, vetoing access to community funds to those projects using converters made in China. “Our risk assessments have confirmed threats, including manipulation of electricity production parameters, interruption of electricity generation and even unauthorized access to operational data. In practice, this could mean a blackout, a remote blackout of Member States’ networks leading to nationwide power outages.” As with the network infrastructure, according to the Commission, this measure responds to a shield for security reasons, applicable from next November 1. Again, a blow to the giant Huawei, one of the main suppliers of solar inverters in Spain. In Xataka 6G is not being developed to improve mobile speed: it is geopolitics and China is going with the accelerator to the table The Chinese response. China is no stranger to the measures being prepared by Europe, and has made it clear that it considers these proposed acts to be discriminatory and harmful to trade. Without detailing his plans, he has made it clear that he will take countermeasures. The Swedish case. Decisions have consequences, and Sweden is a country that knows very well what happens if you ban Huawei on your telecommunications equipment. In 2020, the country banned the use of telecommunications equipment from Chinese manufacturers under the argument of national security. Although a priori this was a lifeline for Ericsson, the consequences were just the opposite. China retaliated, and China Mobile expelled Eriscsson from its network infrastructure, going from 11% market share to 2%. In case Europe hits China again.
