More than 400 cameras will monitor L6 of the Madrid Metro so that it circulates autonomously

by

Line 6 of the Madrid Metro prepares to operate without drivers in 2027. This means that its infrastructure must resolve a series of technical aspects so that the metro can circulate in complete safety. What was previously monitored by a driver must now be done in an automated manner, and here there are a series of technologies that come into play that are worth highlighting. Rethink security from scratch. When a train has a driver, there are a pair of human eyes in the cabin that detect smoke, obstacles, people on the track or any anomaly in real time. Eliminating this figure does not mean reducing surveillance, but rather it must be technologically multiplied. The Circular, the busiest line on the network with nearly 400,000 passengers daily, needs a system that does not leave any blind spots. What does the system consist of? Madrid Metro plans to install more than 400 cameras along the 23.5 kilometers of route and in its 28 stations, with an investment of around four million euros, according to collect the middle 20 Minutes. The network will cover the entire infrastructure in real time: tunnels, ventilation shafts, emergency exits, pumping areas and platforms. As the media reports, in the underground sections between stations, the devices will be placed at very short distances from each other so as not to leave gaps unattended. dset fire before seeing it. Of all these cameras, about 60 will be equipped with specific smoke and fire detection technology, capable of sending early warnings to the control center before a fire spreads. Just like share In the medium, these devices will alternate with conventional video surveillance devices to guarantee total coverage. Security reinforced with technology. At the most sensitive points of the line (the Ciudad Universitaria and Arganzuela-Planetario depots, the Laguna depot and the stations with correspondence to other lines) perimeter fences several meters high, physical barriers and infrared curtains will be installed, technology usually reserved for industrial facilities or airports. All reinforced with controlled access through doors and control points monitored by video. What about the platforms and accessibility. From 20 Minutes they assure that the doors leading down to the tracks, located at the ends of each platform, will have new intercoms connected directly to the line controllers. Its function will be twofold: to authorize access for Metro staff when necessary for maintenance tasks, and to allow people with reduced mobility to request that the train wait longer before starting. It will be the controller who, from the command post, keeps the platform doors open for as long as necessary. Where is L6 right now. The installation of the platform doors is still underway and is forcing the closing to be brought forward from the line at 11:00 p.m. from Sunday to Thursday (two and a half hours before the usual time). Everything indicates that the restriction will remain in place until the end of the year if there are no changes. Meanwhile, the 40 new trains, manufactured by CAF, which have cost the Community of Madrid around 450 million euros, are advancing in production. When will it be ready. If the calendar is met, 2027 will be the year in which the Circular circulates alone for the first time in its more than 50 years of history. This would make Madrid one of the few cities that offer fully automated metro lines, along with Copenhagen or Lille.

More and more women track and monitor it through mobile apps

by

Applications to record daily steps, glasses of water we have drunk, books read, movies watched, progress in the language we are learning… Measuring and quantifying different aspects of our lives has gone beyond the workplace – where tasks, calls or overtime are recorded – to extend to the field of sport, culture or leisure. Technology today allows us to record activities, habits and daily changes that not so long ago were outside of any measurement. This logic has also been extended to the field of health, and especially women’s health. Applications to follow the menstrual cycle They are already common tools: some of the best known, such as Flo or Clue, exceed 100 and 50 million downloads, respectively. And that trend is not limited to women of reproductive age. In recent years, applications designed specifically for perimenopause and menopause have also begun to proliferate, a stage traditionally much less visible. Kala Health, My Menopause either Balance are some examples of this new niche – although many apps focused on the menstrual cycle also incorporate functions to detect hormonal changes or accompany the transition to menopause. From taboo topic to public conversation The menopause –biological event characterized by the permanent cessation of menstruation and the end of the reproductive period as a result of the loss of ovarian follicular activity– and perimenopause –transition stage before menopause– have historically been described by professionals as invisible periods in a woman’s life. There are research that delve into how “the stigma and taboos” surrounding these stages “foster a culture of silence and a marked lack of support.” However, professionals such as Juan José Escribano Tórtola, head of the Obstetrics and Gynecology Service of the Severo Ochoa University Hospitalcelebrate the move from “absolute ostracism” – even among health professionals – a few years ago to “greater information about these periods of women’s lives.” He comments: “More and more women come to our consultations to find out about possible treatments and/or measures related to their health at this stage, and more and more professionals are concerned about finding complete solutions (…) to improve the quality of life of our patients.” (Pexels) Although media coverage continues to be scarce, according to Irene Mira, a journalist specialized in women’s health, social networks, specialized associations – such as Spanish Association for the Study of Menopause (AEEM)— and other dissemination channels – such as books, podcasts, websites or blogs – are facilitating the dissemination of information about menopause and perimenopause. And it is precisely in this increase in visibility (and greater predisposition of women to inform yourself) where the rise of applications that allow tracking these stages is framed. In fact, Dr. Pilar Valenzuela Mazo, a gynecologist specializing in menopause at the Pontifical Catholic University of Chile and creator and host of the podcast Menopause for everyonesees a clear trend in her patients: “More and more women come to the consultation using applications, either to record symptoms or to learn about menopause.” This is how menopause apps work Although each platform has its own focus, most apps focused on menopause and perimenopause share the same promise: helping users understand what is happening to them in this new stage of their lives. These tools usually combine several layers. The first is the symptom log: hot flashes, insomnia, menstrual irregularities, mood changes, vaginal dryness, changes in libido, pain, energy or sleep problems are some of the parameters that allow writing down to detect patterns. Added to this is a second, also common function: explanatory health content. Many include articles, guides or “encyclopedias” on menopause and perimenopause, with information on symptoms, treatments, healthy habits or sexual health. In addition to this offer, some applications include digital accompaniment. It is the case of Kala Healthone of the few tools available completely in Spanish. Talia Leibovitz, CEO of Kala Health, highlights the “community of support among women” and “the possibility of accessing professionals from different areas, such as gynecology, nutrition or mental health.” Explain to Xataka that the intention is to “offer reliable information, monitoring tools and professional support in one place” for a phase that can last years and affect both physical and mental health. Although these are applications with a very specific audience, some of these applications are beginning to show that there is real interest. In the English-speaking market, tools like Balance already have more than 100,000 downloads, while in Spanish the development is much more incipient: applications like Mi Menopause or Kala Health currently have around 10,000 and 3,000 downloads respectively. They can be useful (but not a substitute) For medical professionals and those in the technology sector, the main value of these applications is found in their ability to organize an experience that is often experienced as chaotic. In perimenopause, for example, symptoms can appear intermittently and be confused with stress, insomnia, anxiety or specific changes in the cycle. Recording them can help detect patterns and better understand what is happening in the face of a medical consultation. That’s where doctors and developers agree: digital tracking can be useful if it works as a support tool. The gynecologist specializing in menopause Valenzuela Mazo explains that keeping a record of symptoms helps women come to the consultation with the information “more organized” and, when the data is consistent, it can help the professional better understand the evolution of the condition. (Unsplash) Along the same lines, the head of the Obstetrics and Gynecology Service Escribano Tórtola maintains that this type of monitoring can be “very useful” for doctors and that, in fact, it is already being implemented in many specialized units. The usefulness, furthermore, is not only clinical. In a field marked by the historical deficit of research in women’s health, the data collected by these applications is also beginning to have scientific value. Some are already being used as a basis for studies on quality of life during menopauseas occurs with research supported by the information collected by My Menopause, the app developed by the AEEM. And furthermore, beyond clinical … Read more

the wheels of your car are revealing your position to anyone who wants to monitor you

by

I can think of few uglier scenarios behind the wheel than a puncture going 120 kilometers per hour. Fortunately, tire pressure sensors minimize this risk because they act as whistleblowers in case of mishaps, ranging from a blowout to a simple loss of pressure. They were designed with security in mind and not privacy and that has opened a door: monitor where your car passes. And obviously, where are you. Context. Tire pressure monitoring systems or TPMS are required by law: in the EU since 2014, also in the pioneering United States and other countries such as South Korea or Japan. This system uses small sensors integrated into each wheel to monitor the pressure and send wireless signals to the car’s computer to alert the driver if a tire drops below the set pressure. Due to regulations and validity, there are millions of vehicles in circulation with TPMS and no one perceives them as a risk: they are safety sensors, not connectivity. The discovery. A research team from IMDEA Networks has shown that TPMS sensors continuously emit a unique identification number via radio frequency that has neither encryption nor authentication. The ID does not change, so it works as if it were a license plate. Like that radar that catches you on a specific day and time at a certain point. Thus, anyone with a radio receiver can pick it up and if they do it once, from then on they will be able to recognize that car at any other time. This operation occurs without the driver knowing and, furthermore, he cannot do anything to avoid it. Why is it important. To begin with, because the research team has already confirmed that by crossing the four data from the four wheels, the reliability of the identification is high. Alessio Scalingi, professor at UC3M and one of the authors of the study, summarizes it like this: “data that seems passive and harmless can become a powerful identifier when collected at scale.” But it is also much more discreet than a conventional radar or camera: the TPMS emits radio signals continuously and these are invisible and can pass through obstacles or walls. Hiding is not an option. On the other hand, there is no need to hack anything: the signal is public and by default it arrives unencrypted. In short: TPMS tracking is cheap, difficult to detect, and difficult to avoid. How they did it. To reach this conclusion, the IMDEA Networks Institute research team together with European partners conducted a 10-week study in which they collected signals from more than 20,000 vehicles. The equipment used was a network of low-cost SDR radio receivers ($100 each), which were distributed near parking lots and roads. In that time they were able to collect more than six million messages, which helped them to reconstruct routes and routines, for example what time someone arrives at work or how often they go shopping, the type of vehicle or even whether it transports heavy cargo. The receivers are capable of capturing signals from moving cars at more than 50 meters, even if the sensors are hidden or inside buildings. How it affects you as a driver. You are potentially exposed to monitoring of your car journeys no matter what you do. This sensor goes inside the wheel and has no switch, so as a driver you cannot do anything to avoid this tracking beyond obviously not using your private vehicle. Of course, it requires someone to deploy this network of receivers deliberately. The ball is in the regulators’ court. As the research team explains, the real problem is structural: the TPMS regulations do not require encryption for these sensors, so the solution is not in the hands of users, but in those who regulate and the manufacturers. As concludes Dr. Yago Lizarribarone of the authors of the study: “Our findings demonstrate the need for manufacturers and regulatory bodies to improve the protection of future vehicle sensor systems.” In Xataka | The industry has been filling cars with complex safety systems for years.

what it is, compatible devices and how to use it with a monitor to turn your mobile into a PC

by

Let’s explain to you what is android desktop mode, an option that we have been waiting for years as standard on our devices. This is something that Samsung has been offering it through DeX for yearsand that we have seen on mobile phones like Motorola and some Huawei models. Now, it is starting to arrive as standard on Android. We are going to start the article by explaining how this feature works, and what the concept it pursues is. Then, we will explain its implementation so that you know how it can be activated, also mentioning For which mobile phones is it initially available?although it is to be hoped that as months and years go by it will end up reaching many more. What is Android desktop mode Connect your mobile to a monitor and launch an adapted Android at this screen size. It seems like a wet dream, making Android look like a desktop operating system, but this is the desktop mode that Google is starting to enable. When you are using the mobile in this desktop mode, the entire interface will change. You will have a desk with a lower dock with applications that we have launched. We also have a menu bar above where on the left we see the time and on the right the battery and connectivity controls. You will also have a button that acts as a start menu. Besides that, open applications will be seen in windowsand just like in GNU/Linux and macOS, an indicator will appear in the dock telling you which ones are open. This will allow you to do two or three things at the same time, such as reading the content of a social network in one window while watching a video in the other. In general, the experience is similar to that of a PCand you can even open notifications and quick settings. In fact, you can see the quick settings on a double screen to see the options within the menus. In addition to this, you will also be able to resize and move windows of applications to place them wherever you like on the desktop. You’ll be able to pin apps to the taskbar, show all open apps, and even use Android’s three-button control system. Finally, know that desktop mode It will use the apps that you already have installed on Android. It is not a separate operating system, but an interface that the mobile itself has to launch itself that way when you are viewing it on a larger screen. Desktop mode too It will allow you to use a Bluetooth mouse and keyboard. You will have to link them to your mobile, and when you are in desktop mode you can simply use them as if it were a computer. What mobile is it compatible for? Currently, desktop mode is only supported with Pixel phones from Google. And not with everyone, but from Pixel 8 onwards. You will have to update Android to receive its latest version, and in it you will already have the function natively when you connect your mobile. Being a native Android function, it is possible that over time it will also end up reaching other devices. But as always, you will first have them in the Pixel as an exclusive feature. We’ll have to wait and see when it reaches the others. How to activate Android desktop mode To activate desktop mode, you have to connect your mobile to an external screen. Since the Pixel has a USB-C port, you will have to use a cable with this connector or a cable that connects from USB-C to Micro HDMI, or whatever format the external monitor uses. The mobile will automatically detect that you have connected it to the screen. Then, a pop-up window will appear asking you what you want to do after connecting. In this message, you simply have to click on the option Computer and that’s it. Now connect mouse and keyboard via Bluetooth and voila, your mobile is now a computer. The projector mode that you also have as an option is the one in which you can see on the screen what you are doing on your mobile, but without using it directly on it. The mode to choose is Computer. Images | Javier Pastor In Xataka Basics | The best apps for Android 2026: new, essential and hidden gems

gigantic boards that monitor war conflicts

by

This Saturday, February 28, Israel, with the help of the United States, began a bombing of Iran. Beyond the news, one of the current obsessions is to be informed in real time about the conflict. And this is where the vibe coding You have shown your best face again. Developers are creating online platforms to follow war conflicts in real time with a level of detail that, to date, was not possible with traditional websites. The obsession with conflict. The war has become a board. One that we not only want to be informed about, we want to monitor it in direct time due to its direct implications worldwide. This is where maps, alerts, and interfaces that “gamify” the information experience gain interest. And in recent times the vibe coding has made it clear. The great war board. The obsession with knowing every detail of the global conflict has led developers to create tools such as World-Monitor. Giant information panels in which the conflict can be followed in real time, through each and every one of the necessary pillars: A global map with alert level legend live cameras Live broadcasts from media such as Bloomberg, CNBC, Euronews Adjustment layers to focus attack zone, military bases, submarine cables, data centers, military activity, ship tourism, trade routes Analysis of country instability, overview of strategic risks Independent feed for each area, news, theme Gamifying tragedy. The case of World-Monitor is not isolated, alternatives such as Situation Deck make it clear that this type of panels situation room They want to offer a gamified experience. A visual experience that is more reminiscent of a tactical command center than a traditional medium. Beyond the moral debate, the work of developers vibecoding desktop solutions that offer a much more refined and updated vision than that of many media. Developers are building tools that, in many cases, are faster and more comprehensive than traditional coverage.

monitor disasters in real time

by

There are natural disasters such as strong storms that cause floods, maritime storms or uncontrolled fires in which observing the evolution is providential both when it comes to sizing the mishap and to draw up a strategy for solutions on the ground. In this scenario, satellites are real lifesavers. So Spain and Portugal are going to launch a “atlantic constellation” of satellites that observe the Iberian Peninsula from space to protect it. The context. It is not difficult to find catastrophes that have hit the peninsula in recent years, as an example is the train of storms with which we began 2026 and whose effect can be seen from space or the DANA that destroyed Valencia. Currently, the reference satellites for forest management, fires and emergencies in Europe are ESA’s Copernicus / Sentinel, which generate images of the Iberian Peninsula every two or three days. What is the Atlantic Constellation. It is a set of 16 small satellites, eight launched by each country, which will orbit less than 700 kilometers from Earth, coordinating to generate images of the territory every two or three hours. It is a complement and not a replacement for the European Copernicus Sentinel. Why is it important. The implementation of the Atlantic Constellation brings an obvious improvement when it comes to evaluating progress and planning solutions to disasters: going from having information every 2 – 3 days to doing it every 2 – 3 hours, practically in real time for this type of disasters. On the other hand and as explained for El Periódico Nicolás Martín, director of Users, Services and Applications of the Spanish Space Agency, this is a project “very relevant for the Spanish aerospace sector and for our strategic autonomy.” And although its main mission is emergencies and natural disasters, it also has applications for other sectors and entities, such as agriculture. How are they going to do it? Spain has awarded their part to the Catalan Open Cosmos through a contest. The company will be in charge of designing and manufacturing the state’s eight satellites, while the ICE-CSIC will develop one of the four payloads of each satellite and the geophysical data extraction algorithms. On the Portugal side, it will be GeoSat who leads the project. The ESA will be the one who supervises everything. On each satellite there will be four instruments: high-resolution multispectral optical cameras to analyze vegetation and terrain, GNSS reflectometry sensors to measure soil moisture or sea state, IoT connectivity and a system to identify and track vessels. The roadmap. The first demonstration satellite will be called Pathfinder and according to the project schedule, it will be ready by the end of this year. It will be launched in the first half of 2027, thus serving to validate the integrated technologies before manufacturing the rest of the units. However, the full deployment of the entire satellite fleet will take place in the following years.

China has given the green light to buy NVIDIA chips. The problem for your companies is that you will closely monitor each operation

by

NVIDIA has hundreds of thousands of H200 chips trapped in limbo. It is one of the company’s most powerful chips and the standard of the companies that are training AI. It is preferred for train the modelsand also the weapon with which The United States sought to leave China out of the game. After movements by the two countries, The US finally approved (25% commission through) that NVIDIA could sell the H200 to Chinese companies. China has taken some time, but finally it seems that it will accept the offer reluctantly and with an ace up its sleeve: DeepSeek. The mess. The H200 issue is a soap opera. In the context of the trade and technology warthe United States played one of the best cards they had: preventing one of their most powerful products from reaching Chinese hands. They also hindered European companies like ASML from selling their most advanced machinery for making semiconductors to companies like Huawei or SMIC. China responded, of course. He attacked with rare earth -that control almost exclusively– and has been showing little by little that they can not only create advanced semiconductors on your own (and pushing old technology to the limit), but they are alive and well in the battle for artificial intelligence. Furthermore, they have developed a robotics industry and other aerospace practically out of nowhere, making a vacuum to Western chips, and that has caught the United States on the wrong foot. China makes a move. Seeing that China was advancing and the US was not getting a cent, they moved tab: They opened the door for NVIDIA to sell its H200s to certain Chinese customers. For each sale, the US took 25%, but it seems that it was something that the Chinese Big-Tech wanted to take on because they need, at least currently, that NVIDIA technology. And the GPU company itself increased production expecting two million orders above normal. The problem is that everything moved very quickly. without China, really, having said anything. Because here it is not just a question of whether the United States lets it sell, but whether China wants its companies to buy. In a tense calm that left requests halted and thousands of H200 in limbo, China has finally made a move. According to Reuters, and as we told a few days agothere are companies that will be able to place orders for the H200. There is a “but”. It is not carte blanche for anyone to place an order. According to WSJ, Chinese authorities have indicated that each purchase must be for a use considered “necessary.” That includes advanced research or development in AI. Because two factors come into play here: On the one hand, it seems that there are Chinese companies that are pressuring the Government to let them access the technology. NVIDIA was allowed to sell the H20 to Chinese customers, but if these customers can now buy the H200 – six times more capable – they want to take advantage of it. But China does not want everyone to throw themselves into the arms of NVIDIA because, precisely, they have been building their own semiconductor industry for five years with SMIC and Huawei in the lead. China’s goal is to stop depending on the US, and if everyone starts buying US chips like crazy, they will not advance on the technological roadmap that the country marked a long time ago. That is to say, it seems that Chinese regulators are going to evaluate which companies can or cannot buy the H200 depending on the use they want to give it. It has been reported that, for example, ByteDance, Alibaba and Tencent will be able to import 400,000 H200 chips. But there is a twist to all this. deepseek. China’s quintessential artificial intelligence model is one that has turned both NVIDIA and the United States upside down. The question was how it was possible that, without access to the latest technology, DeepSeek could optimize its AI so much. On the one hand, ingenuity to circumvent the CUDA standard. On the other hand, there are those who are clear that DeepSeek has been trained with NVIDIA cards… smuggled. Accusations of smuggling are nothing new in this commercial and technological war, but precisely, and according to Reutersthe company that joins NVIDIA’s massive H200 order along with ByteDance, Alibaba and Tencent is… DeepSeek. Officially, and without restrictions, they will be able to access the H200. “We have given China the argument to launch its own industry and, at the same time, we are giving them access to ours again” – Samuel Bresnick Whiplash. I really liked this concept that Wired uses to define American policy in this regard. They are the ones who started the conflict and their position has been pivoting about tariffsbut with more or less lax measures depending on the moment. It seems clear that, now, they are at a point where they have had to think “if China is going to somehow reach the technology, at least we sell it and earn something along the way.” Samuel Bresnick is a researcher at the Georgetown Center for Security and Technology and comments in Wired that the worst thing you can do is “come and go,” noting that “we have given China the argument to launch its own industry and, at the same time, we once again give them access to ours.” Get your batteries. And meanwhile, there’s Jensen Huang. The CEO of NVIDIA has taken a mass bath in recent days in both China and Taiwan, where he has met with some of the companies that move the semiconductor sector. NVIDIA sat at the same table, TSMCFoxconn or Asus, and Huang came out, half joking, half seriouswith one request: you need wafers and RAM. Regarding the purchase of the H200, China is walking on eggshells, and it makes perfect sense. It is at a point where it does not want to be left behind, and to do so it needs its … Read more

monitor every move of Russia and China in the Arctic

by

First World War II and then the Cold War turned Greenland into a magnificent surveillance platform belonging to Denmark but granting the United States a VIP pass that it now wants to switch to annexation. Because that piece of frozen land (less and less) has rare earthsbut the most attractive thing has always been its strategic location. Old radars are not enough. The melting of Greenland has opened new sea routes that Russia and China have welcomed with open arms. the advantages it offers compared to traditional routes. Of the 15 military bases that the US had in Greenland in 1945, now only one remains: the Pituffik Air Base or Thule. And a problem: outdated and insufficient systems to monitor what happens there, such as acknowledged the Pentagon first and the Mitchell Institute for Aerospace Studies after. So they have gotten to work to solve it: the United States Department of Defense agency responsible for the development of cutting-edge technologies for military use (DARPA) has requested a new technology collected in Frosty. This program aims to develop new radars that operate reliably in the harsh Arctic environment. DARPA is seeking proposals capable of detecting aerial targets at least 75 kilometers away with a detection probability greater than 90%. The coveted new polar “silk road”. The launch of this new radar is important because it would mean having a real lookout in the Arctic and on the new route that has appeared so that the great world powers can gain commercial and military advantage. China has already made clear what do you want be a “great polar power”“. The immediate advantage is reduce shipping times to Europe from up to 50 days to less than half (on its route through Suez). This recent academic article In its security report, the United States Coast Guard reviews other possible risks such as the expansion of its fishing grounds, access to natural resources for scientific cooperation and mentions the existence of its advanced fleet of modern icebreakers and Chinese submarines capable of operating under the ice. Spoiler: With current technology, they are difficult to detect from the surface. For Russia, the new passage route that is being opened is a threat to the current North Sea route, which operates under its jurisdiction. Furthermore, Greenland is part of the GIUK bottleneck (shared with the United Kingdom and Iceland) that its northern fleet must pass through to reach the open waters of the Atlantic, at the gates of the United States. We are talking about nuclear submarines as advanced as the Borei-A class and the Yasen-M. Also at stake is the sovereignty of the Lomonosov Ridge, an underwater mountain range that links it to Greenland, which could eventually give it exclusive rights to vast hydrocarbon reserves. And that’s without talking about the massive rare earth deposits The technical challenge of being so far north. The northern lights are very beautiful, but they generate a huge amount of electromagnetic noise when they occur. Since the Earth’s magnetic field lines also converge at the North Pole, the ionosphere is unstablegenerating scintillation that corrupts the GPS signal and absorption in the polar cap. In short, conventional radars not only fall short, but sometimes also go blind. The DARPA wish list. What the US agency wants It is essentially transforming the electromagnetic chaos of the Arctic into a detection tool with a brain in the form of processing software with advanced algorithms that dynamically “filter” interference from geomagnetic storms to isolate potential threats. Furthermore, it would not be a single giant antenna, but rather a mesh of small mobile nodes that share data to triangulate targets. These are the radars you request: A passive environmental noise radar that does not simply emit a signal and wait for the bounce, but uses natural radio frequency noise from the environment to detect objects. That is, it does not treat noise as an interference, but as a source. If a ship passes through that noise, it generates a disturbance that can be detected. Radars Over-the-Horizon that, unlike line-of-sight ones, which travel in a straight line and collide with the curvature of the Earth, these are capable of bouncing waves off the ionosphere to be able to detect objects beyond the Earth’s curvature. They are indicated to detect maritime vessels or aircraft flying at low altitude, thus evading conventional radars. An externally illuminated radar with high-power transmitters located at great distances as power sources, like Alaska’s HAARPwhich allows objects to be illuminated indirectly. For when. As mark your roadmapthe receipt of industry proposals for the tender ended on January 30 and the next 18 months will focus on algorithm development, offline implementation and laboratory testing. Between 2027 and 2028, the integration of the software into real hardware would take place, with field tests in Point Barrow and Poker Flat, Alaska. Therefore, to see this new and ambitious radar network in action we will have to wait until 2028. In Xataka | Russia and China already had an advantage over the US in the Arctic.

This is the impressive interactive map to see the Earth in 4K live from space and monitor satellites

by

Cartographically speaking, our planet is fascinating: its evolution over time, what it’s really like taking into account the precision of physics and of course, per se: the mountain ranges, the irregularities of the coasts, the tectonic plates… all of that looks great from space. And be careful, because the space that surrounds the Earth It is full of satellites: only Starlink ones around 15,000 units. But satellites allow us to have a fabulous view of the earth. And in fact, some of the main space projects that monitor the Earth have their recordings open, without going any further, what the International Space Station “sees” either NASA events They are available to anyone. The problem is that not everyone knows it, nor do the tools shine for having a clear and intuitive interface. So to someone who loves astronomy it occurred to him to create it to follow from satellites to shooting stars or racing cars. SatellitesArg Although you can see the Earth from space live and in 4K without doing anything, it is worth setting your location for a more personalized and precise experience of everything it offers. From here, there are several ways to select a satellite to follow, some as intuitive as tapping on “Satellites” and selecting from the list (there are some as popular as Starlink or BlueWalker 3) to see, for example, the ISS live camera. However, you can also save them to your favorites. Another interesting option is “Visible Passage”, which is what happens when a satellite crosses the sky illuminated by the Sun while it is night in your location. To do this, simply select a specific satellite, open it on the map and click “Visible path”. Within “Best steps” those satellites that will be highest and brightest in the coming days are shown. Likewise, there are filters to, for example, see only the steps at dawn or dusk. The “Radar” option is used to locate a specific satellite, something especially interesting if done from a mobilesince with the help of the compass you can hunt it at some point in the sky. You can also view those that are nearby, use augmented reality to superimpose the trajectory using your phone’s camera. Although you can see in real time, you can also go back to monitor past trajectories and have access to astronomical events, the phases of the moon and even have a map of the stars in the sky. But even if you don’t take advantage of all those functions, the option to see the Earth in real time in 4K by tapping on “ISS Live Camera” It is simply spectacular.

For decades, HUDs have projected data onto the windshields of airplanes. and today many cars offer own versions to show speed or navigation without taking your eyes off the road. That principle, project or reflect information on a transparent elementis the one that Visual Instruments ensures have brought to the desktop with Phantom, a monitor that seeks to mix the digital and the physical and that adjusts its transparency in real time. Phantom does not use a panel that becomes transparent on its own, but rather an optical assembly similar to that of a teleprompter or HUD. The image is reflected in a tilted glass and thus appears to “float” over what is behind, with an opacity control that allows it to go from transparent to opaque. The company presents it as “the first transparent computer monitor.” The key to the invention is in the optics, not in a futuristic panel According to the manufacturer, Phantom is presented as a 24-inch monitor in 16:9 format with 4K resolution. The company sets the brightness in a range from 5 to 5,000 nits and places the color coverage at 100% sRGB, figures that must be confirmed when the product reaches the hands of users and analysts. As for the connection, it is limited to the most common options: USB-C with DisplayPort and HDMIwithout the need for additional software to operate. {“videoId”:”x87bool”,”autoplay”:false,”title”:”How to CALIBRATE your MONITOR for VIDEO GAMES and enjoy it to the fullest”, “tag”:”monitor”, “duration”:”230″} It is worth putting it in context. Transparent screens have been appearing in consumer markets for years. LG has been marketing a 77-inch transparent OLED TV since 2024. Lenovo, for its part, has also developed a concept laptop with a transparent panel. The difference here is key: those products use transparent base panels, while Phantom uses, as we say, HUD-type optics. They are different technological routes, with different commitments and limitations. Aspects such as contrast, color representation with different ambient lights, the presence of reflectionsuniformity or comfort in prolonged use remain unknown. It is also unclear to what extent alternating between the monitor and the background can translate into real relief from eye strain beyond the idea put forward by the manufacturer. Everything will depend on the first independent tests and the measurements that are published when demonstration units exist. In Xataka There is a cheap TV sweeping Amazon: after a week of use it became clear in which situations it can make sense Phantom arrives, therefore, as a suggestive idea that has yet to demonstrate whether it can be sustained in everyday use. The commercial status points to a very early and selective launch. The Founders Edition is limited to ten units intended for early adopters, with shipping expected in Q4 2025, 30-day returns, and a one-year warranty. The price is not final: each unit is custom configured, but the company itself compares it to an Apple Studio Display whose price in Spain starts at 1,779 euros.
