We are going to tell you everything you need to know about the total solar eclipse that will be in Spain next August, the first of these characteristics that we have in more than a century. And get ready, because this will only be the first of the total solar eclipses visible in Spain in the next three years. Let’s start blabla Date, time and why this time it is “against the clock” The total solar eclipse will take place next Wednesday, August 12, 2026. It will take place at sunset, and this is a fact that will determine the experience, because it will be quite a time trial. Globally, the phenomenon will start at 5:34 p.m. (Spanish peninsular time) in the Bering Sea, and will end at 9:58 p.m. in the Atlantic. It will last 264 minutes, although in Spain we will see it in its last phasesalmost with the Sun touching the horizon. These are the approximate schedules on the peninsula: Start of the partial phase: around 7:30 p.m. Whole: between 8:27 p.m. and 8:33 p.m., depending on where you are. End of partial phase: around 21:20-21:22. To give an example, in A Coruña the eclipse begins at 7:31 p.m., its maximum is at 8:28 p.m., and ends at 9:22 p.m., with a totality 76 seconds and the Sun only 12 degrees above the horizon. This is a first key, which is going to be something very quick. And the other key is that Spain is at the end of the totality zonemeaning that the total eclipse will be when the sun is very low. This will make vision difficult if you live in mountainous areas, and you will need to be in a place with the clear horizon to the west. Mountains, buildings, or even a row of trees could prevent you from seeing the eclipse properly. The positive part is that, being in August, the chances of clear skies are higher in much of the country. At least if we compare it with other times of the year, although it will always depend on the weather during that specific day. How to know if you are going to see the total or partial eclipse All Spaniards will see something of the eclipse, but not all of us will see the same thing. The totality strip of the eclipse does not cover the entire countryso depending on where you live or where you go to see it you will see one thing or another. This strip of totality, which is what the area where the total eclipse will be seen is called, crosses the country from west to east, from A Coruña to Palmapassing through capitals such as Oviedo, León, Burgos, Vitoria, Logroño, Zaragoza, Teruel, Castellón, València and the Balearic Islands. Outside that band, that strip, in cities like Madrid, Barcelona, ​​Seville, Malaga or Murcia the eclipse will be partial. This does not make it not a spectacle, but it is not as impressive as total eclipses. At Xataka we have done this definitive map of the eclipse. In it you will be able to see the strip of totality, as well as the peninsular area through which it will pass. you also have the official eclipse map in which you can also find information, although all of it is also on the map that we have made. How to protect your eyes from the eclipse It is very important protect your eyes properly If you are going to look at the sun during the eclipse if you don’t want to finish with sore eyes or with any serious eye injury. The most important thing is to search approved glasses who have the registration EN ISO 12312-2:2015. In addition, if you buy in the European Union, the CE marking must also be visible. Come on, don’t buy glasses from the first person who tells you they are for the eclipse. It is important to look at the approval to know that they will protect you correctly. If it has approval everything will be fine, but if in doubt, buying them from planetariums, astronomical associations or scientific entities will guarantee that they are reliable. It is also vital make sure they are not broken or damaged. Make sure the filter is not scratched, loose or bent, and also that some areas are not lighter than others. If there is any sign of deterioration in the area that covers the eyes, it is best not to risk it and look for other glasses. And not, sunglasses don’t workthe glasses that you use the rest of the year to protect your eyes from solar radiation do not protect you from the direct radiation that occurs under the conditions of an eclipse. Sunglasses only meet their own safety criteria for protect us from scattered lightbut not to look directly at the king star. In fact, they don’t block as much UV radiation as eclipse glasses, but enough so that you don’t have to squint, which exposes you to more, making wearing them even more dangerous. Here, remember that it doesn’t matter if 99% of the sun is coveredEven if only 1% of the sun is visible, you must use approved glasses. That certain darkness that occurs during the event does not protect you, but rather makes you more vulnerable. Therefore, I repeat, Always check that your glasses are well approved to enjoy the eclipse safely. How to protect your cell phone if you are going to take photos Of course, many of us will want to take photos of the eclipse. But in a situation as complex as this phenomenon, doing so can also put our device at risk. Of course, let’s start from the basis that we shouldn’t do itmost experts recommend don’t do it neither with a mobile phone nor with a professional camera. Beyond the fact that it is recommended enjoy the event in first person Instead of distracting you by taking photos, a solar eclipse can … Read more

why 3 euro cardboard glasses protect your eyes from an eclipse better than 100 euro sunglasses

by

If you have in mind see the solar eclipse this August 12you may have already started searching approved glasses. Many shops they have jumped on the car and they are launching offers at a very reduced price. Although the truth is that, honestly, it is not necessary to lower the cost much, since the price of eclipse glasses is extremely cheap. And of course, for some people, it is very shocking, since they insist actively and passively that conventional sunglasses do not work for us, but how can my 100-euro Ray-Ban not be worth it and some cardboard glasses that cost me 3 are worth it? With this, as with many things in life, we see that price is not everything. They are not lying to us when they tell us that sunglasses are worthless. They also don’t scam us by selling us eclipse glasses for only 3 euros. The inflated prices of brand name sunglasses can sometimes hurt us like a scam, although everyone is free to set the prices for their brand that they see fit. But let’s focus on the science of approved glasses. How can something so technically necessary be so cheap to produce? There is not so much technical complexity. Eclipse glasses are designed to be used once in a very long time, if at all. Normally, the person who wears them just look at the sky and, at most, around it. You don’t have to drive, walk, or read anything. You just stop and look at the Sun. For this reason, all you need is a very basic frame, sometimes made of cardboard, and two filters, one for each eye. Sunglasses, on the other hand, must be functional, which requires greater technical complexity. If they are graduated, It is necessary that they have an adequate curvature. This is not necessary in itself for non-prescription sunglasses, but it is often also done to give them a more enveloping effect, especially if they are aimed at sports. On the other hand, the glass of the sunglasses is carved, polished and treated to improve visibility and prevent scratches. For this reason, their manufacture is more expensive, while the price of eclipse glasses is very low. Simple but essential filters. The really important thing about approved eclipse glasses is that they have good filters. These must comply with the regulations EN ISO 12312-2:2015which ensures that no more than 0.00032% of visible sunlight is allowed to pass through. Sunglasses, on the other hand, are designed to avoid indirect damage, but not to look directly at the Sun, so a transmittance of 3% is sufficient in the highest protection categories. The filters used to achieve this great light blocking in eclipse glasses are manufactured with a black polymer or resin with carbon particles. The most used polymer is reflective Mylar.. Then, on top of the polymer, they have thin layers of aluminum, chrome or silver, which help optimize filtering. They are not difficult materials to obtain in the necessary quantities, so the final price is not exorbitant. There is no exclusivity, another reason for the price of eclipse glasses. Even if cheap materials are used, the filter still costs money. The thing is that, unlike what usually happens with sunglasses, eclipse glasses are usually produced on very large scales. Exclusivity is not sought nor does anything happen because there are many identical glasses. That, in the end, reduces costs a lot. Furthermore, with sunglasses we often pay for the brand and that is something that, logically, does not matter with glasses approved for viewing the eclipse. Even given as gifts. Producing these glasses is so cheap that some brands, businesses and institutions are already giving them away to ensure that we all see the eclipse on August 12 safely. In Spain, this will be the first of three eclipses in three consecutive years; So, contrary to usual, you will need these glasses again very soon. Whatever you buy, don’t get rid of them. Of course, if you see that the filter is broken or scratched, the protective metal layers may be damaged and good filtering is no longer guaranteed. In that case, buy others. After all, they are justifiably very cheap. Image | Magnific/NASA In Xataka | A third of Spain will be completely dark for a minute or two. The astronomical event of the century is approaching

the initiative of a town in Huesca to make neighbors look each other in the eyes. “We’ll put the cell phone in a bag”

by

The United Kingdom announced a few hours ago that is going to ban social networksamong other things, to those under 16 years of age. In a much more diplomatic line, the Aragonese people of Alcalá de Gurrea will soon celebrate a day without screens to enjoy the best social network: eye contact. This is an experiment that will put the entire town in “airplane mode” and, as you know, people are quite dependentthey will ensure that it is fulfilled in a very curious way. Putting cell phones in a bag with a sheriff patrolling the town. It’s much nicer than it sounds. Town in airplane mode. It will be next June 28 when, for a few hours, the Aragonese municipality will implement this measure. They will invite neighbors who want to join in to leave their cell phones aside to interact with the rest of the town and, as detailed in Chain Beingduring those hours there will only be one cell phone: the one owned by one of those responsible for the activity. “The sheriff will go throughout the town in case something happens and will call the right person if necessary,” the organizers point out. The objective is clear: to make people look each other in the eyes. “The plan is for people to do all kinds of activities but, above all, to interact with each other during those nine hours,” they say. To do this, there will be a group meal, activities such as a kayak experience and common spaces in which various types of activities and creative workshops will take place. What if you’re embarrassed? Well, they have it covered: “the organizers will be waiting for people to break the ice,” they say. The typical “do you know my friend?” of all life. to the bag. And the way to make sure people put their phones aside is to do it…literally. The event, as those responsible in Ser comment, will take place on the outskirts of the town and will be where participants will be given a bag to store their devices. “When you cross the border of airplane mode, there is no turning back: no one will be able to locate you,” they point out. “Since people are so dependent, we will put it in a sealed bag that they will not be able to open for nine hours.” As we read in Zaragoza-Citythe capacity will be very limited in this first edition, of just 200 people and the organizations defend that it is not about giving up technology, but about realizing that we can not be constantly glued to the screens. Not so original. If you are unable to put your phone down for a second (which is not the user’s fault either because applications use sophisticated tactics to ‘tickle’ our brains and that are very addictive), is a good solution. However, you should know that Alcalá de Gurrea is not the only place where this is done. On April 18, Euskadi celebrated the first ‘Family Cell Phone Free Day’ which, basically, was the same: the cell phone was left in a safe and guarded bag to experience a fun day without screens. There is an association called EsMontañas that has also driven a similar initiative in almost 60 Alto Aragonese towns and there are private initiatives such as ‘Offline Club’ that organizes meetings of the style in some cities. Others do it out of obligation. The truth is that the absence of the sound of notifications and not having the phone at hand to pick it up, unlock it and look into space simply on impulse does not seem like a bad idea to ‘detoxify’ the device. Now, it is fine as long as it is voluntary and not an imposition. In Vadgaon, India, every day at 7:00 p.m. a siren sounds which urges citizens to turn off televisions and cell phones with the aim of recovering face-to-face dialogue. And Green Bank, a city in the United States, is a municipality without mobile phones by obligation. Due to the presence of the National Radio Astronomy Observatory implies a radio-silent zone in which mobile phones and Wi-Fi devices are very restricted. Curiously, this situation is a claim for people who want a life without smartphones. In Xataka | The science of “doomscrolling”: how technology hacked psychology so we can’t let go of our phones

UK eyes a “hybrid navy” for the future. Navantia already has an autonomous proposal: the LASV75

by

The classic image of a navy is still easy to recognize: large ships, large crews and long campaigns far from port. But the future that is being drawn around the Royal Navy adds another layer. It is no longer just a matter of building larger or more sophisticated ships, but of combining them with autonomous platforms designed to take on specific missions alongside them. That’s where it comes in Navantia UKthe British subsidiary of the Spanish Navantia, with the LASV75: a proposal for that “hybrid marine” that the United Kingdom wants to explore. The concept appeared on the scene in the Farnborough Combined Naval Eventan event for the naval sector held in the United Kingdom. According to Navantia, the LASV75 has been designed in the country and is framed in a very specific idea: combining manned warships with unmanned escorts and autonomous technologies, including drones. The announcement also comes after the British subsidiary to complete the acquisition of Harland & Wolff assetsa movement with which it has reinforced its industrial presence beyond Spain. LASV75 is, in essence, a large autonomous ship surface conceived from the beginning to operate without a crew. Naval News details that the concept is based on a 75-meter modular hull and a displacement of more than 1,000 tons, a scale that distances it from the idea of ​​a small naval drone. The company proposes it as a platform capable of accompanying conventional ships, acting as escort or serving as support in broader operations. The key is that it is not born as an adapted boat, but as a design thought from the keel to function without personnel on board. A proposal for a navy with manned ships and autonomous escorts The usefulness of the LASV75 is not understood as that of a vessel specialized in a single task, but as that of a platform that changes depending on what it carries. It will be prepared for possible missions such as surveillance, escort, electronic warfare and attack-related operations, always linked to the installed payload. This precision helps us not to oversize the concept: it is not that the ship can do everything by itself from day one, but that Navantia UK presents it as a modular base for different missions. The promise is in that capacity for reconfiguration. Thinking about an autonomous system for relatively controlled waters is not the same as thinking about a platform capable of sustain presence in tough scenarios. Simon Jones summed it up at Farnborough with the example of the North Atlantic: to have a persistent and credible capability in severe cold conditions, you think you need something of this size. The other piece of the concept is how all of those systems connect to the ship. In the mockup presented during the event, a deck prepared for different payloads, interchangeable sensors and a modular mast arrangement could be seen. Everything is designed with standard interfaces, aligned with NATO, so that the modules are as interoperable and interchangeable as possible. It is a relevant detail in an allied naval force. For a proposal like this not to remain an attractive model, something more earthly is needed: shipyards capable of manufacturing it with rhythm, precision and scale. Navantia UK is investing 157 million pounds (about 181 million euros) in its four British centers, Appledore, Arnish, Belfast and Methil, with the intention of turning them into some of the most advanced facilities in Europe. Among the improvements is an automated panel line in Belfast, designed to make large pieces of steel faster, safer and more accurately. The idea is to bring these shipyards closer to the concept Shipyard 5.0 that the company already applies in Spain. The account raised by the company is not only about technology, but also about manufacturing. If, as Navantia suggests, an unmanned vessel can be built at a significantly lower cost than a conventional one and, furthermore, be produced with a certain amount of repetition, it fits better in a navy that seeks to increase its presence without multiplying human and industrial costs. The company adds to this logic a specific objective: to reduce the usual design and construction times of large naval vessels by up to 30%. So we are looking at a ship with a date of entry into service? Not really. What Navantia UK has taught It’s a concepta proposal to enter a conversation that is already open: what navies will be like when large manned ships have to coexist with autonomous escorts, interchangeable sensors and platforms designed and built with shorter deadlines. There the company plays a double card: the accumulated experience of a Spanish group with programs such as the F-100 frigates and the S-80 submarines, and a British industrial base that wants to gain weight in the future hybrid navy.

The next treatment for depression could be in the eyes. They have already successfully tested smart contact lenses on mice

by

Drug-resistant depression is one of the greatest challenges of today’s medicinesince when antidepressants they don’t workpsychiatry and neurology have to resort to therapies such as electroconvulsion. Now, a team of researchers has given this issue a radical turn by developing smart contact lenses capable of treating depression by stimulating the brain through the retina. a study published in the magazine cell shows very good results in mouse models with the use of these contact lenses which have made it possible to reverse the depressive phenotype with a capacity comparable to that of the antidepressant fluoxetine, or better known as Prozac. It is not invasive. To understand the milestone that this study represents, we must first look at the current therapies that involve using what is known as Transcranial Magnetic Stimulation to be able to do non-invasive neuromodulation for patients with drug-resistant depression. The possibility of transcranial electrical stimulation by direct current is also being studied. But the problem with these therapies, which are at the bottom of psychiatry, is that reaching the deep regions of the brain without resorting to surgery is extremely difficult. And one of the risks of applying a strong electric field from the outside to reach the depths of the brain can end up damaging part of the brain. The solution. This physical inconvenience is where temporal interference technology comes in. As detailed a review done in 2025this stimulation is a great strategy, since it consists of applying two high-frequency electrical currents that do not affect the superficial brain tissue. In this way, when crossing in the deep areas of the brain, the frequency difference creates a new low-frequency wave that does stimulate the target neurons. It is a functional concept that was demonstrated for the first time in mice and that allows access to the depths of our anatomy without a scalpel. Some contact lenses. Under this principle is where we are now looking for a way to apply it in a way that is comfortable for the patient and is where the use of contact lenses equipped with electrodes made with gallium and platinum oxide comes into play. Here the direct anatomical connection that exists between the eye and the brain through the optic nerve is used to transmit this stimulation through the retina which allows temporary interference signals to be sent to the neural networks involved in depression. The application. In the research, this stimulation was simply applied for 30 minutes a day for three weeks in the rodents. What was achieved here is a restoration of healthy brain oscillations and a behavioral improvement that, according to the researchers, is comparable to that obtained by administering fluoxetine in these same animal models. Caution. Here we must keep in mind that this is the first time that contact lenses have been used to treat a brain disorder, and although the design of the device is a display of engineering, we must be cautious. As is often the case with these advances, the transition from the laboratory to the patient is very slow due to the need for numerous trials to assess the effect and safety in humans. But the idea is already on the table right now and we just have to wait for science to continue advancing.

NASA has an appointment with Mars today (although its ship already has its eyes set elsewhere)

by

The Psyche spaceship, launched by NASA in 2023 to study the asteroid with the same name, it will reach its destination in 2029. However, today it will make its first stop along the way. If we stop at gas stations and roadside bars to stretch our legs and have a coffee, Psyche will approach Mars at almost 20,000 kilometers per hour, to tune some of its instruments while taking photographs worthy of the best wallpaper. In fact, we can already see some of them. Too close for space. Psyche won’t stop at the gas station like we did, but she will make a great approach. At 3:28 PM EDT (9:28 p.m., Spanish peninsular time), will be located 4,500 kilometers from the red planet. That, in spatial terms, is very little. Gravity assist. At this stop along the way, Psyche will take the opportunity to take some photographs and adjust her instruments, but she will also use Mars as a springboard to reach her destination faster. When a ship approaches a moving planet, it is attracted by its gravitational field. It does not touch the planet, but that interaction changes its trajectory and helps it gain speed with less propellant expenditure. We can imagine it as a ball being thrown towards a moving vehicle. This changes its trajectory and also gives it speed on the return trip. Psyche uses solar-electric propulsion, with xenon gas as fuel. Thanks to that push, known as gravitational assist, you can save quite a bit of propellant. A whole entourage. The result of this interaction will be studied by the two NASA rovers that are currently on Mars, Curiosity and Perseveranceas well as by American and European orbiters that are carrying out their respective missions. Not only photographs will be taken. Possible changes to the Martian surface and atmosphere will also be detected. first photos. Psyche has already taken a very interesting photoin which the night side of Mars is seen as the spacecraft approaches it. The result is something similar to a half moon, although logically it has nothing to do with it. The real goal. Thanks to Martian gravitational assistance, Psyche will reach the asteroid with the same name in 2029. This is located in the asteroid beltbetween Mars and Jupiter. Shaped like a potato and 278 km long and 232 km wide, it is a metallic asteroid, one of the least abundant types in that location. That’s why it’s so interesting to explore. In fact, it is believed that it is actually the iron-nickel core of a planet in formation that could not complete the process because it was destroyed by cosmic collisions. For all this, Psyche (the ship and the asteroid) has a lot to teach us about the birth of a planet and, possibly, about the dawn of the solar system. As we often say, to know where we are going, it is also important to know where we come from. That is what makes this type of research so important.

Three settings for iOS and Android that are more effective to avoid straining your eyes if you have presbyopia than changing the text size

by

If you are already a few years old and presbyopia is starting to make an appearance, don’t limit yourself to making the text on your cell phone bigger. Let’s tell you others three most effective adjustments to avoid straining your eyes that you can turn to, and that are available on both Android and iOS. These are three fairly simple adjustments that are not going to be as disruptive in terms of showing less content on the screen as when you increase the font size. However, they are going to be even more effective in helping you read. The key is contrast, bold and white balance. Expands screen contrast In the accessibility options of your mobile you have an option to increase contrast or high contrast text. By doing so, there were no more pale grays or blues that are difficult to read, the mobile will force the apps to show the maximum contrast in your texts to make them easier to read. You can combine this option with reducing transparency on iOS or disabling blur effects on Android, to eliminate some translucent effects that can make content difficult to read. Turn on bold text On iOS, within the text display and size section in the accessibility options you will have the option to activate bold text. With this you will make all the letters of the operating system, from the clock to the notifications, appear in bold. This will make all text easier to read without having to make it larger. In Android 16 you will have an even more advanced option, which is outlined text, within the Screen and text size section in the accessibility options. This will add a small border to each character to make it much easier to read, even when there are complex backgrounds behind it. Adjust the white balance The third setting that I recommend you try is the white balance. In iOS the option is called Reduce white pointand it’s in the display and text size settings in the accessibility section. On Android the equivalent is in the screen tone settings, within the section Screen. With this, what you will do is reduce the intensity of pure whitesnot the brightness in general. By doing so, the screen will be less bright, and it will be more comfortable for your eyes to read, especially when you are using your mobile at night or in poorly lit areas.

the subtle change on your screen that your eyes will appreciate after eight hours of Excel

by

If you work or study for many hours every day in front of the PC screen, It is very likely that you will end up with tired eyes: reading a lot of text, watching videos, going from one Excel to another (and then to another, and another), writing, editing images or videos and a very long etcetera of tasks sustained over time will almost certainly cause you to have eye fatigue and a tiredness in your eyes that is as uncomfortable as it is unhealthy. If you have no choice but to be in front of the monitor for a good handful of hours each day (something quite common in many cases, in these times), you can always do everything possible on your part to minimize it and even remedy it: Get up every now and then, don’t stare too long at a time and look at distant objects, stand at a distance that prevents you from straining your eyes too much, and more similar tricks. And added to all this, I am going to give you an idea that perhaps you had not considered and that is not going to solve your life, but it will make you gain visual comfort (and I say this from experience): using a monitor with a high refresh rate. Even if you don’t play. Because having more than 60 Hz (120 Hz, 144 Hz and even more) is an excellent idea outside of the field of video games. And (spoiler) nowadays, the price difference between some monitors and others is so small, that I can tell you that it is very worth it that little extra investment. What is refresh rate (and what does it affect) Okay, on paper, purely speaking of specs, 120Hz is better than 60Hz. And 144 Hzbetter than 120 Hz. That has become clear to us. But exactly what are we talking about? We are talking about hertz, which in short determine the number of frames per second that the screen in question is capable of displaying. In other words: the number of still images that appear, one after another, in one second of time. The greater the quantity, the more fluid the image, which can be a video game, a video or the apps we use in our daily lives. The latter, just what we are looking for. In practice, having more than 60 Hz and therefore a higher refresh rate translates into fluidity. Fluidity in everything: transitions, application effects, window and cursor movements, scroll much softer and, ultimately, everything that generates movement on the screen. Something that may seem minor, but in the long run, and after spending hours in front of the monitor, it is noticeable. A one-way road. At this point, we must take into account the ‘price factor’. Because long ago, going above that base 60 Hz from which monitors start was expensive. However now, with refresh rates that even exceed 360 Hzwe find 144 Hz (or 120 Hz, or 165 Hz and even more) options at great prices. Which means that for a fairly contained investment you can make a huge leap in quality. The good and the bad, face to face Although the theory is simple, the differences between one type of monitor and another can be confusing if you are not familiar with it. Then, This table as a summary will clarify it a lot for you.. 60Hz 144Hz THE GOOD 🟢 Cheaper (and you can allocate more budget to other specifications: resolution, size…) Great fluidity in images and a standard to play today THE BAD 🔴 They offer less fluidity and are somewhat outdated in 2026, as they can make the jump to 144 Hz or more at similar prices Slightly more expensive than 60 Hz and, in general, more striking gaming design IDEAL FOR Users who do not feel visual fatigue, who feel comfortable at 60 Hz and do not want to spend more Gamers (or non-gamers) who want to take a leap in visual comfort Which one may interest you more: we do the math As we have already mentioned, price is not a determining factor today when deciding between a 60 Hz monitor and another with 144 Hz or more. Even so, if a 60 Hz one is enough for you, you can dedicate that extra investment in other aspects of the screens, such as the resolution, the diagonal or the format. Actual use: 60 Hz is enough for you and you prefer to spend what 144 Hz would cost you on a ultrawidebecause you need more horizontal space on the screen. What experience you get: similar to what you have been obtaining with previous 60 Hz monitors, but you gain in those other characteristics that are important to you (more diagonal, different format, more resolution…). If, on the other hand, you notice that after finishing the work day your eyes are very tired and it seems that applications, transitions and other movements are not as fluid as you would like, then going from 60 Hz to 144 Hz or more is an excellent decision. Spending little more than you would with a 60 Hz monitor, you double (and even more) its refresh rate and the view thanks you. Actual use: It bothers you that the animations of the operating system, the scroll or the passing of the cursor across the screen goes in fits and starts and you decide to go above 60 Hz. What experience you get: From the first second, you see that everything runs more smoothly and is more comfortable for the eyes. Where before there were almost imperceptible but existing cuts, now everything is going smoothly. It even looks like you’ve upgraded to a better PC! In summary: 👉 Choose 60 Hz if: You don’t notice visual fatigue because you don’t spend too many hours in front of the screen, you don’t want to spend more and you also don’t play games or plan to do so in the short term. … Read more

the “eyes” to anticipate Russia’s drones

by

Since the beginning of the Russian invasion, Ukraine has had to fight a parallel battle far from the front: to convince his allies of what weapons he needed, when and how far that aid could go without cross sensitive political lines. Between delays, partial vetoes and fears of escalation, air defense became one of the most critical bottlenecks for months, leaving kyiv exposed to campaigns missiles and drones while the international response moved more slowly than the war. A radar that changes the calculation. Therefore, the arrival in Ukraine of the Spanish radar LTR-25 launcher represents a qualitative leap in its air defense, by incorporating a long-range detection capacity capable of identifying threats to more than 450 kilometers. From drones and cruise missiles to ballistic systems and stealth aircraft, radar will help in a conflict where Russia has made massive and combined air strike one of its main instruments of attrition. The system, developed by Indra, is neither a prototype nor a future promise, but rather a technology already validated by NATO on its eastern flank, designed to operate in environments saturated with interference and electronic warfare and to integrate without friction with the Western batteries that protect the Ukrainian sky. The unexpected ally. Another reading of the movement is clear. Ukraine has just received from Spain what it had been taking for months claiming the United States: a true long range defense that allows us to see Russian attacks coming early enough to organize an effective response. While Washington has been reticent to give up certain sensors and strategic capabilities, Madrid has taken a step that changes the Ukrainian defensive depth, offering not only interceptors, but the necessary “eyes” to anticipate and coordinate defense against waves of missiles and drones that seek to saturate the system. In that sense, the LTR-25 is not just another radar, but a critical piece that extends reaction time and reduces Ukraine’s structural vulnerability to Moscow. Technology proven in the most demanding environment. The LTR-25 radar operates in L-band with phased array architecture and digital beam forming. In other words, it has characteristics that allow it track hundreds of targets simultaneously with great precision even under electronic attack, a key capability to detect low radar signature targets such as Shahed drones or cruise missiles. Your mobility tactics and philosophy “turn on, detect and move” reinforce its survival on a front where Russia tries to hunt radars and command systems, and its integration with command networks and NATO control makes it a force multiplier for systems such as Patriot, SAMP/T, IRIS-T or NASAMS already deployed in Ukraine. Silent revolution of Spanish industry. For decades, Spain maintained a low profile in defensebut in the meantime it was building an advanced technological base that today emerges strongly on the European stage. Here one name rises above the rest. Indra, with one of the largest radar factories on the continent, has supplied systems to countries like franceGermany or the United Kingdom, and now translates that knowledge into a real conflict that acts as possibly the toughest testbed imaginable. Hence this delivery symbolizes a profound change: from discreet partner to strategic provider of critical capabilities in high-intensity warfare. Beyond the gesture. If you also want, the delivery of the LTR-25 It is part of a much broader shift in Spanish policy towards Ukraine, one backed by an unprecedented military and financial support package and staged at the highest level by Spanish President Pedro Sánchez alongside his Ukrainian counterpart, Volodymyr Zelenskyy. Beyond symbolism, the contract with Indra opens the door to future deliveries if the system proves effective, consolidating industrial cooperation that reflects a broader European trend: technological alliances of all colors that, pushed by war, evolve towards full and lasting defense associations.

“You can’t trust your eyes to know what’s real anymore.” Instagram CEO announces that the feed is dead

by

That the Internet as we knew it no longer exists is not a surprise: it has been filled with search results generated by artificial intelligence and from ‘slop‘. The consequences are already visible: clicks have been reduced by halfwhich is catastrophic for the media. But not only the text is suffering from this barrage of AI that blurs everything: already We do not know how to distinguish if an image is real or notwe have gone from document our life on social networks to the era of influencer content favored by the algorithm to videos and images that are not real, but can pass as such. There are no longer four fingers that are worth it. Instagrammers, the feed is dead. And this is also going to take its toll on social networks. Adam Mosseri, CEO of Instagram, closed 2025 with a publication in the form of a presentation of 20 images where he reflected in depth on what is coming: “the era of infinite synthetic content”, the antithesis of a more personal Instagram that has been dead for years. For Mosseri, AI has turned the carefully maintained grid with its algorithm into something of the past: “Unless you are under 25 years old and use Instagram, you probably think of the app as a feed of square photos. The aesthetics are careful: a lot of makeup, skin softening, high-contrast photography, beautiful landscapes,” Mosseri’s sentence falls like a stone on this millennial, who still uses Instagram as a kind of photo album. “That feed is dead. People largely stopped sharing personal moments on the feed years ago.” Tap to go to the post In search of something real. Mosseri explains that now its users keep their contacts up to date on their personal lives with “improvised photos of unflattering shoes and poses” shared via DM. And this also affects content creators: the omnipresence of images made by AI is going to bring a change: goodbye to those pro-looking photographs in favor of a more real and improvised aesthetic: “Flattering images are cheap to produce and boring to consume. People want content that feels real.” In fact, the CEO of Instagram points to manufacturers, applicable to cameras and mobile phones, who he says are making a mistake by democratizing the ability to “look like a professional photographer from 2015.” Because RAW images with defects are still a sign of reality until AI is able to copy them. But what is real? The time has come to unlearn to believe what our eyes see, something we have been doing all our lives. Javier Lacort explained that our entire epistemology (ranging from court testimony to photo albums) is based on the fact that seeing is a way of knowing. If you see a tiger, there is a tiger. If you see a photo of a tiger, someone has been close to one. This no longer applies: the era of uncover organized fake news has made way for anyone with Nano Banana Pro can get such an absurdly realistic image with a basic prompt in just a few seconds. Now creating a deepfake is trivial. Adam Mosseri think equal. “For most of my life I was able to safely assume that photographs or videos were largely faithful captures of moments that actually happened. That’s clearly no longer the case, and it’s going to take years to adjust. We’re going to go from defaulting to assuming that what we see is real to starting from skepticism. To paying attention to who’s sharing something and why. This will be uncomfortable: we’re genetically predisposed to believe our eyes.” If you can’t beat them… The paradigm shift has already occurred, so now Instagram and other platforms have to adapt to this new reality: “we have to build the best creative tools. Label AI-generated content and verify authentic content. Show credibility signals about who is posting. Continue to improve the ranking of originality.” It is the apocalypse of what is a photo that we have been predicting for years. Focusing on Instagram, Mosseri talks about how “we like to complain about ‘AI junk content,’ but there is a lot of amazing content created with AI.” He doesn’t give concrete examples or talk about Meta tools to make this possible, but Meta has already added AI tools on Instagram and Facebook. Without going any further, his AI Studio allows you to create personalized chatbots to deal with your followers. New times, new identification measures. It is increasingly difficult to identify content in AI, so it proposes fingerprints and cryptographic signatures in cameras to identify real content, forgetting about labels or watermarks. In any case, it advocates greater transparency about who publishes on the platform and improve creativity so that its human users can compete with content made in AI.

And there are those who have already seen a business niche: content made by humans In Xataka | There is a generation working for free as a documentarian of their own life: they are not influencers but they act as if they were.
