We have been observing the snow of the northern hemisphere from space for 40 years. The conclusions of the latest major study are devastating

by

As some older people around us say: winter is already it’s not what it was. As we move forward in the decade, scientific data paints an increasingly clear and disturbing picture of the amount of snow that has accumulated in some parts of our planet. And the images seem to leave no room for doubt, since they suggest that snow coverage in the northern hemisphere is constantly reducing, altering the seasonal cycles that govern our climate. The data. The last job we have had access to was published in January of this same year, and the conclusion they have drawn is quite devastating when pointing out that 24% of the regions of the northern hemisphere show a significant decline in the presence of snow, compared to a mere 9% that has registered an increase in its amount. How it looked. To reach these conclusions, researchers have not limited themselves to looking at the thermometer. They have turned to a gigantic high-resolution database that brings together historical data since 1980 with information on both snow and ice. Mathematical model. But the real advance in this case lies in the use of advanced statistics. And, expanding on previous research from 2023, they have applied a two-state Markov chain model, which in simple terms is a mathematical model that allows analyzing the spatial and temporal probabilities of snow persisting or disappearing in specific grids on Earth over decades. That is why we are facing one of the most rigorous methodologies that currently exist to understand snow trends, eliminating the “noise” of the precipitation that is coming in the coming months. Early spring. But… Where exactly is the snow disappearing? The Markov model reveals that the decline is not uniform, but there is an alarming pattern that directly affects our side of the globe: spring melt is coming forward dramatically in Europe and Central Asia. Right now we are seeing snow melting earlier, shortening winter temperatures and directly altering the water cycle, which is vital for agriculture and ecosystems during the warmer months. The consequences. But it is not something new, since previous works already warned of this loss of snow, which is a decline that not only affects water reserves, but also the ability of the Earth’s surface to reflect solar radiation. Something that is not nonsense, since less snow means more exposed dark land, greater heat absorption and, consequently, an increase in regional temperatures. A consensus. In addition to this study, in 2025, research was also published that analyzed possible biases in climate records. NOAA historicalconfirming that the decline in snow during autumn and winter is a real phenomenon and not an erroneous measurement. But it does not stop there, since the last Arctic bulletin painted a very extreme scenario, since, although there was above-average snowfall until May 2025, the decline during June was so rapid and abrupt that snow coverage was reduced to half of what it was 60 years ago. A mixed and volatile pattern that shows a climate system under stress.

Setting up guest Wi-Fi seemed like a good idea. Until the latest vulnerability has appeared: AirSnitch

by

I’m the first one I have activated a guest Wi-Fi network to facilitate access to Wi-Fi connectivity for my friends and family, without compromising the security and privacy of the Wi-Fi network to which the rest of me is connected. devices in my home. The coffee shop I usually go to does it too. Separating the main network from the one used by visitors or clients seemed enough to prevent someone connected from snooping on other people’s computers, cell phones or printers. However, that model just took a major setback. A group of researchers has presented in the NDSS 2026 a attack called AirSnitch which shows that this separation can be broken even when the router has isolation between devices activated and uses modern encryption such as WPA2 or WPA3. The problem with AirSnitch is that it is not a brute force attack against these protection systems, but rather it has found an alternative path in which this protection simply does not arrive. AirSnitch is not an attack, it is an alternative AirSnitch is not an out-of-the-box malware, but rather a technique that exploits a vulnerability in the way many access points implement client isolation. This function, present in all home, business or public Wi-Fi networks, should prevent two devices connected to the same Wi-Fi from being able to communicate directly with each other. The problem, according to the study presented in it Network and Distributed System Security Symposiumis that this isolation is not part of a single standard and each manufacturer implements it in its own way. In their tests, the researchers analyzed 11 different devices, from home routers to professional equipment and alternative firmwares. They found vulnerabilities to AirSnitch techniques in all of them. In statements collected by Ars TechnicaXin’an Zhou, one of the authors of the work, stated that AirSnitch “breaks Wi-Fi encryption around the world and could have the potential to enable advanced cyberattacks. Our research physically taps the entire wire for these sophisticated attacks to work. It is truly a threat to the security of networks around the world.” How AirSnitch works The key is that, although the devices are “isolated” from each other thanks to the customer isolationshare certain internal mechanisms of the router that allow data traffic to be organized. AirSnitch takes advantage of that feature to trick the access point and make some of the information that should go to another device pass through the attacker first. In practice, this allows you to place yourself in the middle of the communication without the victim realizing it, generating what is known in cybersecurity as a Man-in-the-Middle (man in the middle), in which all the information on that device first passes through an intermediary. From there, the attacker can observe data and, in certain cases, modify it before it reaches its destination. That is, it is not about guessing the Wi-Fi password, but rather taking advantage of how the device itself router manages connections internal once someone is already connected. The researchers showed that this technique can facilitate additional attacks, such as redirecting the victim to fake pages or manipulating certain internal communications if they are not adequately protected. Isolation, which was supposed to prevent precisely this scenario, stops be an effective barrier. The main problem is that all devices connect to the same router that manages them. Why public networks are the most delicate scenario The risk is especially relevant in open or shared networksF for many people: cafes, airports, hotels or coworking spaces. In these environments, any user can legally connect through the password provided by the establishment and, if the access point is vulnerableattempt to exploit the flaw against other clients connected at that time. In one home network the impact is much more limitedbecause the attacker needs to know the password to enter first. That is, it has to be one of the guests to whom you have given the password, not someone external. Still, research shows that activating a guest network does not alone ensure that devices are completely isolated. Being a recent discovery, there is still no immediate universal solution for the end user. The fix depends largely on firmware updates by manufacturers or deeper changes in how they design their device isolation systems. Meanwhile, in enterprise environments it is recommended to segment networks more strictly, using configurations that truly separate devices into different internal environments and do not depend solely on a router function. For individuals, keeping equipment up-to-date, using strong passwords, and avoiding sensitive operations on public networks without additional protection are reasonable measures to reduce risk that continue to be in effect. Need a password to connect to a Wi-Fi network It is not a guarantee of security or privacy.

Verdeliss’s latest challenge reminds us that impossible challenges are huge business

by

Before we get into the matter, let me ask you an indiscreet question: What did you do between seven in the afternoon on Wednesday and the same time on Thursday? Most likely several things, including eating, sleeping, and stretching your legs. Of all of them Estefanía Unzu, better known by her alias ‘Verdeliss’he only did the last one. And in an unorthodox way. During 24 hours the influencer He dedicated himself to running on a treadmill installed behind a shop window in Madrid. It is the umpteenth proof of two trends that they walk run hand in hand: business and the fever generated by impossible challenges, a field that Verdeliss know well. What has happened? If in the last few hours you have stopped by the Decathlon store in Nuevos Ministerios (Orense Street, Madrid) it is quite likely that you have been surprised. On Wednesday the 25th at 7:01 p.m. in its window you could see a treadmill with a runner taking strides. At 2:00 a.m. the image was identical. And at 6:59 p.m. on Thursday the 26th, the same thing happened. The surprising thing is that during all that time (the 24 hours from 7:00 p.m. on Wednesday to 7:00 p.m. on Thursday) the person who ran on the treadmill was always the same: Verdeliss. His balance: 24 hours of walking and more than 250 km. Why did he do it? Advertising. The challenge is part of the campaign orchestrated by Decathlon to promote the sneakers Kipride Maxof Kiprunthe brand with which the French chain aspires to expand its space in the growing business athletics and amateur running. In fact, the company has been in charge of giving visibility to the Verdeliss challenge on its networks, with videos, photos, interviews with passers-by and of course to the influencer herselfwho before starting to run assured that his objective is to test his limits. The underlying purpose: to take advantage of the challenge to give notoriety to the new Decathlin sneakers and provide them with a place in a hypercompetitive market, in which large multinationals such as Adidas or Nike work in different price ranges and frequently launch promotions. Kiprin introduced the Kipride Max ago just a monthpromote them as daily training shoes “designed to offer the brand’s most cushioned and comfortable ride.” Why Verdeliss? Because of his public profile. Runners there are many. Influencers, too. Estefanía Unizo Ripoll (‘Verdeliss’) has however managed to gain notable fame. And it has done so with two ingredients: an unconventional profile and a commitment to extreme challenges like Decathlon. The influencer Navarre has 40 years, eight children and combines his love for extreme sports with his businesswoman facet and media figure (he reached go through Big Brother). Since he joined YouTube in 2008, his profile has also changed: from basically publishing family content he has turned towards extreme sports. If his name sounds familiar to you even if you don’t follow current events running maybe it’s because in 2025 he went for it World Marathon Challengea test that consists of seven marathons in seven days and different continents. And that is just one of the challenges he has conquered. Another is the national championship 100 km on the road. Why is it important? Because Decathlon’s challenge not only tells us about it. It also tells us a lot about the fever (and business) generated around impossible challenges. People like to explore (or see how others explore) physical limits, whether climbing skyscrapersjumping from heart attack distances either swimming and running enormous distances with hardly any breaks. Behind many of these initiatives there are sponsorships (also campaigns with a more or less solidarity approach) and above all a huge media exposure for those who star in them. Verdeliss, for example, adds some 1.6 million of followers on Instagram and others 2.1 million on YouTube. The organization of extreme events also opens a business avenue: without going any further, participating in the World Marathon Challenge requires paying tens of thousands of euros. With yesterday’s campaign, Decathlon manages to position itself in a hypercompetitive market and the influencer (beyond the promotional agreement itself) feeds her image as an athlete capable of conquering extraordinary challenges, traveling 255 km in 24 hours. In the background there is another debate: to what extent facing challenges like this pushes the body to its limits. In the past Unzu herself has recognized having done “savages” and who does not seek to be “exemplary.” In fact, he even warns his followers: “Don’t do this in your house.” Images |Decathlon (IG) and Verdeliss In Xataka | The Winter Olympics leave Italy with a debt of 7.8 million dollars.

It is a serious mistake according to the latest study on Alzheimer’s

by

To this day, Alzheimer’s disease continues to be one of the greatest challenges in medicine to understand why it occurs, to lead to better treatments. And although pharmacology is advancing in leaps and bounds to try to stop it, science makes it increasingly clear to us that lifestyle is our best weapon to prevent the disease. And we not only talk about the diet either physical exercisebut also of how the brain is ‘trained’ with writing or reading. Some activities that we are losing. New evidence. A new study published in the prestigious magazine Neurology has pointed out that having “cognitive enrichment” throughout life can reduce the risk of developing Alzheimer’s by 38% and delay the onset of the disease up to five years. Although here the question is how the brain can be enriched to avoid this devastating disease. A protective shield. The study is based on a small sample of 1939 peoplewith an average age of 80 years and with 75% women, who did not have any type of dementia at the beginning of the experiment. From here they began to follow them for eight years with different annual evaluations to determine the degree of dementia they had. But what exactly is “cognitive enrichment”? The team of researchers measured the exposure of these individuals to intellectually stimulating environments throughout their lives, which include such everyday and accessible habits as reading, writing, learning new languages, visiting museums or libraries, and having educational resources at home from childhood. The results. Once all the data was analyzed and cross-referenced, it was possible to see that the people who had the greatest cognitive enrichment showed an incidence of Alzheimer’s of 21%. This is a figure that increases as less intellectual and cultural activity is seen, until reaching an incidence of 34% in those patients who are in the 10% range of cognitive enrichment. Overall, the group with greater stimulation had a 38% lower risk of Alzheimer’s and a 36% lower risk of mild cognitive impairment. Delaying the disease. Beyond the risk percentages, the most important thing is the delay in the onset of the disease. Here the study found that people with a highly stimulated mind delayed the onset of Alzheimer’s in about five yearsmanifesting on average at 94 years of age compared to 88 years of age in the group with less stimulation. In the case of mild cognitive impairment, the “delay” achieved was even greater when the disease debuted at age 78 to age 85. What is it due to? One of the most fascinating aspects of the work comes from analyzing different corpses to see what was happening in their own brains depending on the lifestyle they lived when they were alive. And here it was seen that cognitive enrichment did not prevent amyloid plaques from forming, which is one of the causes of Alzheimer’s. What was seen here is that people who had kept their minds active with writing or reading showed much slower cognitive decline and better memory and thinking ability, even when their brains already showed the physical damage associated with dementia. It is as if the brain, having been trained and nurtured for decades, had built other pathways to continue functioning efficiently even though the main pathways began to collapse due to the ‘junk’ in the brain generated by the disease. There are nuances. In this case we have focused on an observational study based, in part, on the memory of the patients’ own experiences, such as what they did fifty years ago. This shows an important association, but it is not a direct coincidence or indisputable by other studies. However, the findings do not fall on deaf ears, but rather They add to a mountain of previous evidence which suggests that prior enrichment reduces the pathologies associated with Alzheimer’s. This makes science point to the recommendation of dedicate at least one hour a day to hobbies and reading can protect our brain. Technology against us. It is a reality that today some activities such as handwriting have declined in favor of writing on a tablet or computer to take notes or write emails. This is also added to the fact that audiobooks are beginning to have a lot of weight in our daily lives, which means that we train our brain less and less to put on and read a good book. In this way, keeping the brain busy with activities such as crossword puzzles, sudoku or any type of activity can be essential to stop diseases as devastating as this one.

all the changes and improvements of the latest update for iPhone and iPad

by

Let’s tell you what’s new in iOS 26.3the new update with additional features for iOS 26. This is a very minor update with hardly any changes, but it prepares the ground for the great revolution that will come with iOS 26.4. In fact, what the main new features of this new version have in common is that They arrive thanks to the demands of the European Commissionwhich have pushed Apple to be less closed and favor more interactions with devices from other brands. What’s new in iOS 26.3 These are the new features and corrections that Apple has announced for this new update. They are official changes with all the new things that you will find on your iPhone after updating. RCS encryption: RCS is the technology that converts the SMS sending application of any Android and iPhone mobile into a WhatsApp, being able to send rich messages with multimedia totally free between devices of all brands. Now, Apple has added end-to-end encryption. Transfer data to Android: Apple makes it much easier to transfer your data to an Android mobile. This does not come from the goodness of his heart, but from European demands. The configuration to do so will be within Settings > General > Transfer or reset iPhone. Here you will have a new option Transfer to Androidand by clicking on it you can scan the QR of the other mobile to proceed to move photos, videos, contacts, calendars, notes and other files. Notifications on third-party watches: Another change that comes thanks to European demands. Your iPhone will now allow you to better manage notifications on watches from other brands beyond the Apple Watch. For that you will have to go to the option Notification forwarding within the notification settings. Better third-party headphone pairing: Thanks to European requirements, you will now be able to pair headphones from other brands to your iPhone just by bringing the case close to it. Come on, the same as with the AirPods. Automatic switching on third-party headphones: Apple has also had to open up the flagship feature of the AirPods. With this update, the possibility of automatic switching between devices with headphones from other brands is added. Come on, if they are connected to the iPhone and Mac, you will go from one device to another depending on which of them you are using. Better location privacy: In iOS 26.3 you can limit the location to a general area, reducing the precision with which the mobile network can know where we are. All this without affecting the quality of the calls. At the moment this is not available in Spain, and it affects only very few operators and few devices, only iPads and iPhones with Apple’s own 5G modem, and in some operators in Germany, the United Kingdom, Thailand and the United States.

with his latest Rosco, he has achieved audiences typical of the last century

by

Rosa Rodríguez has entered the history of Spanish television, thanks to the 2,716 million euros she won in the legendary final rosco of ‘Pasapalabra’. The nightly special gathered 4.1 million viewers at its peak (a 45.3% share), figures that seem taken from another decade. But what is notable is not the prize or the specific audience, but rather that this contest, broadcast outside the prime timehas maintained for 25 years a capacity for convening that defies all logic. The fragmentation of audiences pulverizes formats each season, but ‘Pasapalabra’ grows. What happened. After 307 duel programs with Manu Pascual, Rodríguez, an Argentine teacher living in Galicia, completed the Rosco that gave her access to the largest jackpot ever awarded by ‘Pasapalabra’. Rodríguez and Pascual starred in the longest duel in the history of the program, 307 broadcasts faced in the final Rosco, a mark that far exceeds any other confrontation in the format. Pascual accumulated the absolute record for individual participations with 437 programs, and on six occasions he was one letter away from completing the rosco. On Thursday night, Rosa correctly resolved the 25 definitions (from “cruiser” to “Earl Morrall”, the American football player who closed her victory – not without controversy, since her pronunciation was not entirely correct, which triggered the inevitable on social networks. tongo accusations-) and dethroned Rafa Castañountil then holder of the largest jackpot with 2,272 million euros obtained in March 2023. Pascual left the contest with 270,600 euros accumulated, a considerable figure that does not mitigate the frustration of having touched the jackpot on half a dozen occasions. The audience. The data turns Pasapalabra into a statistical anomaly. This season, the contest registers a daily average of 1,928 million viewers with a 20.3% screen share. These figures correspond to its usual evening broadcast, in a time slot, eight in the afternoon, which the industry does not consider prime time and which competes with the end of work days, commuting and family routines. The tentacles of Pasapalabra. The impact of the program transcends its own broadcast. On Thursday Antena 3 reached 18.9% daily averagedouble its usual performance. ‘The Anthill’with Rosa and Manu before Rosco, scored a spectacular 23.5% of shareits best figure since March 2023. Vicente Vallés’ nightly news program reached close to 3.1 million viewers, its highest in three years thanks to the audience awaiting the outcome. The evening magazine ‘Y Ahora Sonsoles’ and the daily series ‘Sueños de Libertad’ also recorded season highs dragged by the ‘Pasapalabra’ effect. It was the day with highest television consumption of the entire seasonwith 10 million Spaniards in front of the television after 11:00 p.m., 20% more than the previous week. A revealing fact: the final Rosco segment alone reaches a 25% screen share and 2.6 million viewers on average, surpassing the global audience of the entire program. It is the moment of maximum tension, when the secondary screens turn off. 25 years. The permanence of ‘Pasapalabra’ in the Spanish television ecosystem for a quarter of a century is complex to explain. Since its debut on Antena 3 in July 2000, the contest has aired on three different networks, several judicial stoppages and presenter changes. It has not lost cultural relevance. Its format maintains a deliberately simple structure: two contestants accumulate seconds in verbal agility tests that they then invest in the final Rosco, 25 definitions whose answers correspond to the alphabet. That invariability is, paradoxically, one of its greatest attractions. An anomaly. The context in which Pasapalabra thrives makes its success even more surprising. At the end of 2024 63.3% of Spanish households with Internet access used at least one paid audiovisual platform. Netflix, Amazon Prime Video, Disney+ and the rest of the on-demand services have radically reconfigured consumption patterns: viewers decide what to watch, when to watch it and on what device to play it. The rigidity of the traditional television schedule should be an obstacle, but it is not However, the numbers refute the supposed obsolescence of linear television. Digital platforms accumulate 16.7% of total audiovisual consumption in Spain, and traditional television maintains 83.3% according to a Kantar analysis from July 2024. Among those over 50, free-to-air television continues to be the dominant medium, with consumption exceeding three hours a day on weekends. ‘Pasapalabra’ capitalizes on that type of audience. The unique touch. What distinguishes ‘Pasapalabra’ from extinct formats like ‘Who wants to be a millionaire?’? Its ability to generate events within the routine. Each Rosco is not just another episode: it is a potentially historic event, a unique opportunity to witness a record. The architecture of the growing jackpot transforms the daily broadcast into a series with no pre-established end. The suspense builds up for months until it explodes on nights like this Thursday. At prime time. Atresmedia’s decision to move the delivery of the boat to prime time generates a recurring debate among Pasapalabra’s loyal audience. Miguel Aparicio, director of the program, recognized that initially the team resisted this strategy: they preferred to “reward that follower who pays attention day after day” while maintaining the surprise factor. When Rosa completed the Rosco, Antena 3 built an entire programming architecture around the event, with a special prior to 8:00 p.m. in the program’s usual time slot, the appearance of the contestants on ‘El Hormiguero’ and finally the broadcast of the decisive Rosco after 11:00 p.m. This tactic has been repeated with the last big jackpots: Pablo Díaz in July 2021 (30.8% and 4.3 million), Rafa Castaño in March 2023 (37.4% and 4.5 million) and Óscar Díaz in May 2024 (30.1% and 3.2 million). They were all moved to nighttime hours after weeks of building expectations. The strategy works. Not only for the contest, which multiplies its usual audience, but for the entire grid.

The latest Stranger Things deepfake is so amazing that it shows that reality is beginning to be optional

by

This week, a Brazilian content creator named ederxavier3d published an amazing video on his Instagram account. In it they appeared several of the protagonists of the series ‘Stranger Things’ making just the gestures and expressions that he made in the lower window. He explained that he had achieved it in a simple way and thanks to the new Kling 2.6 and its characteristic Motion Control. This option allows the movements we make in a video to be transferred to any real or fictitious person, regardless of the style in which they are represented (it can be a comic book character) with an amazing result. And in the case of the Brazilian creator’s video it can be clearly seen: these videos could perfectly pass for real in almost all cases. It is true that if you look closely you can sense that something is wrong, but only because the video has been shared making it clear that it was created with AI. This video has once again awakened a debate that has been linked to this type of deepfakes for some time. Justine Moore, partner at investment firm a16z, explained that “we are not prepared for how quickly (video) production flows are going to change with AI. Some of the latest video models have immediate implications for Hollywood. Endless character swaps at negligible costs.” How the story has changed. In April 2023 we proposed a little game to all of you who read us: Would you be able to distinguish a real image from one generated by AI? At that time, AI was already achieving remarkable results—the image of the Pope with the coat proved it—but the feeling was that we could still tell whether an image had been created with an AI or not. With the video things were even clearer.because at that time AI video generation I was in diapers. Three years later things are very different, and there are several AI platforms (I see 3, Sora 2Kling, Runway) that generate videos that anyone could easily confuse without problems. Tell Will Smith. ederxavier3d’s video also demonstrates this, and in fact something unique happened with it: there were rumors that the Stranger Things characters had actually recorded those appearances and the creator had imitated their movements, and then rumors appeared that denied that this was true and that suggested that from the beginning the videos were nothing more than what they seemed: deepfakes created with AI. A priori everything would suggest that this is the case: the Kling 2.6 feature is not at all new and other platforms allow our movements and gestures – and even our voice – to be transferred to a character generated by AI. The problem is that At this point it is almost impossible to distinguish whether that person who appears on the screen is real or not. This technology is extraordinarily striking and causes that “wow effect” that AI companies so seek, but despite the creative options it offers, the risks here seem especially notable. The identity theft It is now easier to achieve than ever, and that will probably mean that we will see many more dangerous cases. It is enough to remind the employee that transferred 25 million dollars believing that the person who told him via videoconference was his real boss. It is not clear how, for example, Hollywood studios will react to this technology, but for now some are already taking action on the matter to try to protect themselves. The best example is Matthew McConaughey, who these days has “patented himself” to have one more legal resource (which we are not sure is necessary) to protect yourself against possible videos impersonating you. The implications are enormous, and we are entering an era in which something disturbing is going to happen: We will not be able to trust what we see on a screen.

Ukraine’s latest tactic is an explosive turn for the war. It’s called “letting in,” and the Russians are falling into the trap.

by

Since the Russian invasion of Ukraine in 2022, the front has been mutating with all kinds of tactics who sought to wear down the enemy. The arrival of drones everything has changedbut the strategies and ingenuity In the use of artillery they have remained a fundamental asset for the advance or defense of the front. For this reason, Ukraine’s latest strategy has disconcerted the Russians. When they reach the bunkers there is no one, and then the surprise comes. Win by letting in. Ukraine is applying a more flexible and lethal defense consisting in “pre-register” their artillery on their own front-line positions, so that when the Russians assault and capture them, they literally enter an already calibrated point to be destroyed: the fort falls, the enemy concentrates, and then comes the massive punishment that turns Russian success into a death trap. After that blow, a Ukrainian assault branch recover the points again devastated, closing a cycle that maximizes ranged damage and reduces the exposure of own infantry, something key in a context of growing shortage of trained soldiers. This logic, denounced even by pro-Russian voices as the strategy of “letting in” is actually a way of imposing the pace: it is not about always preventing them from advancing, but about making each advance expensive, slow and bloody. The “death zone” as doctrine. The tactic works because the battlefield has become in a “kill zone” permanent where the defender attempts to maintain a deadly gap between the leading edge and the rear: artillery is placed further back, out of the usual range of rival drones, and forward positions are fortified to attract attackswaiting for the enemy to enter to destroy them right there with fire and drones. The drone operators They not only strike at the front, they also hunt for supply and reinforcement routes, and any activity near “newly taken” positions becomes visible and attackable. Added to this is the constant mining (including remote) and the use of “ambushers” in the few possible logistical axes, so that the attacker not only pays to capture, but also pays twice as much to try to consolidate. The “let in” tactic after pre-registering a position The decisive blow. The most surprising point about this approach is that the defender does not seek so much to “hold every meter” as to prevent the attacker deploy your second step– When the advancing force attempts to bring in specialized reinforcements (e.g. drone operators to hold the ground), the defender launches fast local offensiveseven if they cost material, to keep the death zone intact and keep the enemy trapped in a space where they cannot settle. Thus, the advance exists on paper or in the drone image, but it becomes tactically sterile: you capture something and, before transforming it into a usable position, it becomes a slaughterhouse, like is described in sectors like Kupiansk. It is a war where “letting in” is not an extra: it is the moment in which the enemy advance stops being progress and becomes a loss. The psychological and moral consequence. These types of dynamics are eroding the offensive will because it forces us to choose between kilometers and livesespecially the “faces” of competent soldiers who know how to move in that death zone: It’s not just that advancement costs, it’s that it costs exactly the most valuable thing. From this arises a dilemma on the front itself: advancing in a big way without preparation means burn trained unitsbut advancing “minimally” or little to be able to report presence saves resources… at the cost of generating absurd situations where you can no longer request fire on positions that officially “they are yours”although in reality they are being crushed or disputed. In this framework, the information war of territorial control is mixed with real survival, and “progress” becomes a very diffuse decision. The technological revolution to the rescue. we have been counting. The bottom line is that Ukraine is at the center of a military transformation: soldiers are the most expensive and difficult resource to replace, while unmanned systems have passed to dominate the combatexpanding on an industrial scale, lowering costs and multiplying impact. The front is increasingly managed from the rear or bunkers with operators controlling the space, and attempts at “classic” breaches become almost suicidal: the key is no longer to launch columns, but to disperse, camouflage and gradually push the death zone back. As the war evolves into swarms, AI coordination and persistent attacks, the advantage is not having the most expensive weapon, but having thousands of cheap weaponsreliable communications networks and the ability to update systems non-stop. The coming war. Thus, the strategic decision moves to logistics and industry: cut off land routes, protect supplies, attack factorieslogistics centers and hidden commands, and do so with reusable media and unmanned is increasingly determining. Victories depend on producing drones en massesecure components, sustain communications Starlink type and dominate the cybernetic layer that can blind, uncoordinate or paralyze an entire front. That is why the strategy to “let in” It does not seem like an isolated trick, but rather a direct consequence of the new battlefield: if the first to enter dies, the one who waits and finishes with precision (with drones, mines, artillery and digital coordination) keeps the initiative even if it seems that is receding.

That, of course, is assuming that the panel cannot be rolled and unrolled, because if possible, concepts as curious and peculiar as the one that Lenovo has shown at CES 2026 could be achieved. Lenovo Legion Pro Rollable (Concept). That is the name given to the laptop with a roll-up screen that Lenovo showed at CES in Las Vegas. It is, as its name indicates, a concept, that is, it is not for sale, but its proposal is striking. Lenovo is betting big on this technology with folding laptops and the roll-up concept we tested a few weeks agobut with this device the firm goes a little further.

Lenovo calls this size the “Focus mode.” Under the panel is a dual voltage-based motor that allows the screen to expand and contract “with minimal vibration and noise,” according to the firm. Lenovo also claims to have used low-friction materials and that the system maintains constant tension throughout the panel, which should translate into less abrasion during the winding cycle. From 16 to 24. The panel can be expanded in two sizes: from 16 to 21.5 inches (“Tactic mode”) and from 21.5 to 24 inches in a more panoramic format that Lenovo has dubbed “Arena mode.” This, depending on the player profile, may make all the sense in the world since it allows you to have an ultrawide monitor available at all times.

Titles like ‘Counter Strike’, ‘Valorant’ or ‘League of Legends’ are played in 16:9 because this format allows you to see the entire screen without having to move your head. In some shooters, like ‘Battlefield 6‘, an ultrawide monitor moves the minimap, game and weapon information away from the center, forcing us to take our eyes off the reticle even more. That is to say, in games in which everything happens in the center and surrounding areas, a 16:9 monitor is the most suitable, at least on paper. However, simulation games, open exploration worlds or more cinematic games (think of a ‘Clair Obscure: Expedition 33‘, a ‘Cyberpunk 2077‘ or a ‘god of war‘) appreciate the panoramic format and the immersion they provide. The same with editing and productivity apps, which win in ultrawide. This laptop offers us, in theory, the best of both worlds: a 16:9 panel for shooters and competitive games; and an ultrawide panel for when we want to relax and enjoy a good story. But that, in theory, because the Lenovo Legion Pro Rollable is a concept and, as such, has yet to prove itself. And inside? Lenovo hasn’t left anything out. The laptop is based on the Legion Pro 7i, so it has a New generation Intel Core Ultraa NVIDIA RTX 5090 and the Lenovo AI Engine+. This uses Lenovo LA1+LA3 cores to optimize resources based on the gaming scenario, which, on paper, should conceptually keep the FPS up to par.

They have dismantled the latest Huawei phones and what they have found is bad news for the US: 57%

by

May 2019, this was the date the United States declared that Huawei was “a threat to national security”thus becoming the first major victim of the trade war against China. Without being able to use American technology, the company was mortally wounded, or that’s what we believed so. Today, Huawei has not only achieved return to the top of mobile phones in Chinahas also become the banner of technological independence. 57%. It is the percentage of Chinese-made components that we can find in the Huawei Mate 70 Ultra launched in 2024 and the Huawei Pura 80 Ultra launched this same year. They tell it in Nikkei Asia where, in collaboration with the Japanese firm Fomalhaut Techno Solutionshave disassembled both models to analyze the internal components. It is the result of six years of efforts to become independent despite the vetoes. The turning point. The US veto forced Huawei to look for alternatives and create new national supply chains. In 2020, the percentage of Chinese components in Huawei flagships was only 19% and in 2023 it increased to 32%. Reaching 57% in 2024 represents a jump of 23 points, which is said to be early. The countries where most of the components that Huawei managed to supply came from were Japan, the United States and South Korea. Processor. It is the Kirin 9020, the first manufactured entirely in China and most critical component of all. It is a 7nm chip manufactured by SMIC. To achieve the 7 nanometer process they would have used multi-pattern techniquesquite a technical feat considering that they do not have access to the newer machines, but rather have done so by “tweaking” old ASML machines. More components. There are more key parts that have managed to be manufactured entirely in China, such as the RAM memory, which is produced by ChangXin Memory Technologies, or the storage, produced by Yangtze Memory Technologies. For OLED screens, almost all the components are Chinese, specifically from the company BOE Technology Group. Challenges. The 2019 veto was a near-death blow for Huawei; sales fell dramatically and there were moments when we had serious doubts about its continuity, until it began to resurface. Being able to manufacture critical components in China is an enormous achievement, but there is a reality and that is that, technologically, Huawei is several years behind. To put it in context, the Kirin 9020 that they launched in 2024 is at the level of the Snapdragon 855 or the A12 Bionic launched in 2018. The challenge now is to manage to cut positions and Huawei is already doing it. The Huawei Mate 80 Pro mounts the Kirin 9030which has managed to cross the 7nm barrier and reach 5nm. Furthermore, recent leaks indicate that They have managed to copy an ASML SVU machine which would allow them to go even further, although at the moment it is not ready to produce commercial chips.
