The Samsung Galaxy S26 Ultra has shown us a wonderful future. One full of screens with privacy technology

by

Many revolutions come without us realizing it and by surprise. As if they were a supporting actor that no one seemed to pay attention to and turns out to be the real star of the movie: This is how the privacy screen arrived of the Samsung Galaxy S26 Ultra: an innovation that no one expected and that made the AI ​​or the cameras of that mobile barely matter. Because although all those things add up, they are an evolution that we were all waiting for. But the privacy screen thing is something else: it is an everyday revolution and so obvious that one can only think how it is possible that we are in 2026 and no one would have invented something like this before. Samsung, as our colleague Ana Boria rightly says – please, don’t miss the Short -, has suddenly destroyed the entire industry of tempered glass that protects privacy. For years we have seen how it was possible to add a “privacy protector” in the form of protective glass to our mobile phone or laptop. With it it was possible to prevent any curious/gossip from taking a look at our device over our shoulder, but Samsung has made these protectors no longer necessary, because it has shown us how this technology can be part of the device’s screen itself. The idea is not entirely new, of course. HP has already applied a similar idea in some of its laptops a whopping 10 years ago. He called it Sure View and developed it in collaboration with 3M. That technology effectively allowed the viewing angles of the EliteBook 1040 and 840 to be critically reduced, but the proposal did not seem to work. Image: Samsung. Samsung, however, has gone a step further because this privacy screen can not only be activated and deactivated whenever we want: it can even be activated or deactivated in a personalized way for each application: if you want the privacy screen mode to be activated every time you look at your bank application, you just have to select this option in the settings. The customization of this feature is also extraordinaryand Samsung allows you to adjust it so that it is activated automatically, for example, when we receive notifications, or that the screen also goes into “anti-gossip” mode just when we are entering a PIN for an application. With the function activated, the screen only looks good to those looking at it from the front. This is one of those ideas that show that not everything is invented in the world of technology and that a real practical and everyday improvement as “silly” as this can be much more important and impactful than some AI options that remain fireworks. In fact, here Samsung has surprised us with an innovation that should make apple blush: the Cupertino company does not stop boasting that They are the champions of privacyand although they have certainly traditionally stood out in this section, here Samsung has left them biting the dust. To them and to everyone. Privacy screens have already become one of the clear technological innovations of 2026. Now We just hope that all manufacturers follow the story and end up implementing similar systems on their mobile phones. That may take some time, of course, but today it seems inevitable to think that what Samsung has done is open the door to a wonderful future in which we will be much safer from gossip. Good for Samsung. In Xataka | Image | Xataka with Freepik

We have been searching for the origin of life in hot puddles for years. Bennu has shown that radioactive ice works just as well

by

When the capsule OSIRIS-REx mission landed in the Utah desert in September 2023, NASA knew it had a treasure on its hands. We are talking about a bit of black dust that was collected millions of kilometers from Earth and that was about to rewrite one of the most important chapters of science: the origin of life. What we knew. Until now, the predominant theory regarding the origin of life told us that for “cook” all the basic components of life, such as amino acids, heat and liquid water were needed to make a kind of hot chemical soup. However, science has just flipped the script: the bricks of life They are not only formed in heatbut they can be born in the most extreme cold and under gamma radiation. And that completely changes our understanding of how we got here, and also of the possible presence of life in any corner of the Universe. The importance of Bennu. Definitely is the protagonist of this whole story, and it is nothing more than an asteroid of about 500 meters in diameter which functions as a fossil from the early solar system. But the most interesting thing is that it is approximately 4.6 billion years old, the same age as the Earth, although, unlike our planet, its surface has not melted or been drastically altered by geological processes throughout its ‘life’. And little by little we are learning more about this asteroid thanks to the samples brought by OSIRIS-REx that had already been confirmed in preliminary analyzes an unusual abundance of carbon, nitrogen, water and organic compounds. But what the team led by Penn State University has now found goes one step further. The surprise. This same team, when analyzing the isotopic composition of the amino acids present, especially glycine, came across a chemical signature that did not fit with the classical theory of formation in hot water. A radioactive freezer. Until now, we thought that amino acids in asteroids were formed primarily through aqueous alteration processes: ice melts from heat, liquid water interacts with rock, and voilacomplex organic chemistry. However, science now suggests that liquid water is not necessary for amino acids, an essential molecule of life, to form. Simply from simple ice they can arise without much problem. And there are many of these in the universe. The catalyst. The other important factor in this formation was the energywhich in this case came from gamma radiation emitted by radioactive elements that were abundant in the early solar system. And the energy could not come from thermal heat, since this process occurs in icy environments, long before the asteroid was compacted or heated enough to have liquid water. This explains why we found amino acids both in asteroids that underwent a lot of water heating and in those that remained “drier” and colder. Life, it seems, is more stubborn than we thought and can begin to develop in the most hostile conditions of the vacuum of space. An increasingly complex menu. But we are not just talking about simple molecules, since analyzes of Bennu samples have identified a variety of compounds. Among these is tryptophan, which is an essential amino acid, much more structurally complex, and vital for terrestrial life. Besides, DNA and RNA components have been detectedin addition to ammonia and amines, surpassing in richness many samples of famous meteorites such as that of Murchison. Backlash to Panspermia. If amino acids can easily form in irradiated ice grains in the solar nebula—before the planets even formed—it means that these “ingredients” are spread throughout the solar system. The fact that Bennu, a B-type carbonaceous asteroid, is packed with these compounds reinforces the idea that Earth didn’t have to produce all the components of life itself. A constant shower of asteroids and meteorites during the late intense bombardment could having “sown” our planet with a pre-made deep space biological starter kit. That is why in the end looking at a grain of Bennu dust is looking at ourselves. Or, at least, to the chemical great-great-grandparents who made us here today.

A Brazilian has shown that having Internet in mid-flight is possible with Starlink. It has also shown that it is a real danger

by

If the Internet does not reach the plane, let the plane reach the Internet. One of the Azul Linhas Aereas travelers must have thought something like this, who along with another hundred passengers began to discount the first minutes of their flight. A flight that began on the ground but has not yet ended. And our protagonist tried to connect to the Internet during takeoff using a Starlink antenna and a battery that far exceeded the maximum allowed capacity. The flight has landed but is not over. And the company is now investigating what happened. On Instagram. It’s where the Azul Linhas Aereas traveler has published his invention with the following text: “Who hasn’t suffered the frustration of getting on a four-hour flight and not having Internet? When you get on the plane and the WiFi doesn’t work… Your problems are over.” The video briefly shows how the passenger places the Starlink antenna on the window and hooks it to the window blind. From it, a cable hooks up to a large battery stored in the pocket of the front seat. Click on the image to go to the original post What is Starlink? Starlink is a internet service through satellite connection designed by SpaceX, Elon Musk’s company. The system is simple, with thousands of satellites orbiting around the earth, the service seeks to ensure that a small antenna can provide Internet to anyone anywhere in the world, no matter how remote it may be. To do this, the customer mounts the antenna and points it towards the sky. From there a signal arrives that is interpreted by a router included in the pack to, in turn, multiply the signal so that we can connect to the network. Its latency is high compared to fiber optics, so it is not a system to compete with home connections, it is designed to provide Internet to areas without 4G or 5G coverage. And does it work on a plane? Of course, the operation is exactly the same as if we placed the antenna on the ground. In this case, what the airline passenger did was put the antenna in the window pointing outside to improve signal reception. For the rest, it works exactly the same as if we contracted Starlink to have Internet at home. In fact, Starlink service is being offered to airlines. And although it has been the trigger between the latest tantrum between Elon Musk and Michael O’Leary (CEO of Ryanair), the truth is that Starlink will be offered this year on Iberia, British Airways or Vueling flights. And the first tests with United Airlines They were already very satisfactory. Starlink improves what is already known because, although a plane also connects via satellite to offer Internet on its flights, the bandwidths that customers demand and its applications are increasing, which has been reducing the speed of data transfer that each device on board can enjoy. But it’s a danger. However, what this passenger has done is a real danger that is being investigated by the airline. In the Brazilian State Post Office They explain that the Starlink antenna was powered by a 60,000 mAh portable battery. Its 222 Wh capacity is far from the 100 Wh maximum that can be carried on board a plane according to Brazilian aviation regulators. Large power banks can be a danger on board, so Aeronautical authorities limit them in size and number. And it is that batteries can self-combust if a thermal leak occurs, which may be caused by overheating or a blow that results in a short circuit. The problem is already huge if we are on land But it can be much more serious if the plane is fully operational because lithium ion batteries are very difficult to turn off and, in addition, they release gases that are harmful to our health. That is why the size of the battery is limited and if an incident occurs, it is manageable by the crew.

The Spanish business that Vodafone sold as ballast is now worth three times as much. Zegona has shown that the problem was the owner

by

according to further Populi Voicea medium with a good track record in telecom exclusives, Telefónica has started talks with Zegona to acquire Vodafone Spain. The negotiations are recent (just a few weeks) and it was Movistar who picked up the phone first. Telefónica wants to close the operation in the first half of 2026. The rumors come from months ago. The problem is that arrive late, and that has a price. A little more than two years ago, Zegona bought Vodafone Spain for about 5,000 million euros. Vodafone (the British parent) was selling a problematic asset: It was the third operator in a market of four. He was caught between the scale of Telefónica and the agility of the low-cost He inherited a network that required constant investment. And he also inherited a tarnished reputation after years of complaints. For the British group, Spain was a drain of money and effort. For Zegona, a poorly managed gold mine. And in just two years, the fund has proven that he was right: Has returned to its shareholders 1.4 billion euros in dividends (28% of what was paid by Vodafone Spain). Has reduced the number of shares in circulation by 69%. And yet its current capitalization is around 3.6 billion. For fund shareholders, the return has been spectacular: The stock went from 345p when they bought Vodafone (less than 100 when they announced their intentions) to over 1,565p now. It has multiplied by 4.5 in two years. Vodafone Spain generates around 4.5 billion annual revenues and, with more focused management than before and without the bureaucracy of a global giant, it has become a profitable operation that Zegona can continue to exploit… or sell to the highest bidder. Telefónica is now negotiating from a weak position. It needs the operation (Marc Murtra has repeated that Movistar must lead the consolidation of the Spanish market) and the market knows it. An ERE of 4,500 people has just closed. And while Telefónica prepared the house to add more furniture, its price has fallen 27% since the end of October. Zegona, however, its value has skyrocketed. The price of this indecision is between 2,000 and 7,000 million extra euros. regarding what the purchase of Vodafone Spain would have cost in 2023. Zegona is in no hurry. It can wait, it can squeeze, it can even stay as it is. Telefónica now cannot afford that luxury because buying Vodafone Spain is not an expansionist move, it is an almost defensive necessity: needs critical mass before Europe forces further consolidation where Movistar is the main course, not the diner. But when negotiating is a necessity and the other side knows it, the price stops being a variable and becomes a toll. If the operation crystallizes, it will create a giant with more than 45% of the Spanish market, great cost savings by eliminating duplications (headquarters, networks, contracts…) and intense regulatory scrutiny from Brussels. Although not as brutal as it would have been with Vestager because Ribera has another look. Telefónica knows it and so does Zegona. The difference is that one is late and the other can afford to wait. That changes everything in a negotiation.

Russia has shown on video how to hunt drones with shotguns. And he has also revealed what he did not want us to see

by

During the years of Russian invasion of Ukraine we had seen many tactics that copied techniques and weapons from the past. For example, the use of the Davis cannon of the First World War, or the application of anchored shotguns on airplane wings. In fact, the use of shotguns and rifles from the last century has become a normalized scenario over the months due to the lack of modern artillery. Russia has now shown in a video how to hunt drones. Although he has also inadvertently revealed another detail. Shotguns in the front. The silent battle that is fought every day between Russian boats and swarms of FPV drones in the Dnieper has revealed now one of the most unexpected tactical turns of the war: the resurrection of the shotgun as a survival tool on a battlefield dominated by sensors, radio waves and munitions costing just a few hundred dollars. The viral sequence recorded from the helmet of a Russian marine, it offers a deceptively heroic portrait of a crew sailing at full speed through narrow channels while shooting down drone after drone (up to 13), although the meticulous analysis of each fragment shows that the initial epic falls apart as soon as the details are examined and what is behind it is understood: a fragmented combat, recorded on different days, in which the probable casualties are left out of the shot and where the electronics have as much weight as the shots. The mirage of the mission. They counted it analysts at Forbes. What seems like a single continuous episode in reality It’s a montage of multiple confrontations, where the sky changes color between shots and where the marines shoot at both real threats and invisible threats, lost among interference and gusts of wind. The barge sails while three shooters with semi-automatic shotguns, an automatic rifle and a light machine gun try to keep at bay drones that explode at the slightest contact. Thirteen devices fall, but the editing hides both the failures and the side effects. Two explosions centimeters from the hull leave doubts about possible injuries that are never shown, while a revealing detail (a Marine who already has a tourniquet placed preventively on his thigh) speaks of very specific expectations: the probability of being hit is not a hypothesis, but an assumed fact. Elite unit supported by electronic warfare. Forehead to the ‘Mobiks’ sent to slaughter with weeks of instruction and precarious material, this unit stands out for modern equipmentfor the shooting discipline and for the hidden arsenal that really explains part of their survival: a antenna constellation electronic warfare mounted on the boat. These inhibitors, with a range of between 50 and 100 meters, turn many drones into uncontrolled projectiles that fall by pure gravity. The shotgun just finish what electronics has already weakened. In an environment where FPV munitions explode even when the operator loses signal, the difference between living or dying depends not solely on aiming, but on the ability to blind the drone before it gets too close. That is why the shots show drones collapsing far from the effective range of the shooters: they did not fall due to an accurate shot, but due to interference. The limits of the shotgun. That a shotgun can take down an FPV at close range is so true as misleading. The scene has fueled a narrative of false confidence that the soldiers themselves deny off camera. There are testimonies of teams that five drones were shot down followed to fall before the sixth when they ran out of ammunition, or patrols that aimed and fired until the last cartridge before a device entered through the window and destroy the vehicle. If you like, the arms industry has also adapted: Benelli already produces models specific “anti-drone”equipped with tungsten ammunition, and foreign donors have sent hundreds of semi-automatic shotguns to Ukrainian units. But the tactical principle does not change: a shotgun does not compete with the mass production of drones. It is a desperate tool to gain seconds in an environment where each drone costs less than a box of ammunition and where both armies manufacture them by the millions. Desperate defense. He video ends with the boat rescuing another group of marines: one is wounded, others advance with two weapons in their hands, and the scene, far from glorifying the resistance, underlines the true tactical message. The shotgun works, yes, but only when the number of drones is small, when the shooters are trained, or when there are active inhibitors and when luck is on the side. The complete story, the one that never goes viral, remembers that for every boat that returns, another does not. In the Dnieper War, the shotgun is not a weapon of air supremacy: it is the final spark that is fired when all else has failed, a defense of last resort against a swarm cheap and numerous which is redesigning the way armies move, attack and survive. A shotgun may give you time, but in an FPV-saturated front, that time may not be enough. Image | RUSSIAN MOD In Xataka | Ukraine has just reduced what took days to two minutes.

Grokipedia claims to aspire to the truth. An investigation has just shown that he cites neo-Nazi forums and conspiracy websites

by

The proposal of Grokipedia came accompanied by a direct message: aspire to “the truth and nothing but the truth,” as stated by Elon Musk in X. That statement takes on a new context. after the publication of a Cornell Tech study which examines how various entries are constructed and what fonts they use. The analysis shows that, along with content inherited almost literally from Wikipedia, there are articles that use sources cataloged by academic institutions and verification organizations such as neo-nazi spaces or openly conspiratorial sites. At first glance, Grokipedia takes on a familiar appearance: a home page dominated by a search engine and articles with headings and references. The inner workings, however, are much less transparent. Users do not have a clear system to suggest changes and, at the top of some entries, the label “Reviewed by Grok X weeks ago” appears, indicating an intervention by the AI ​​chatbot without detailing criteria or those responsible. In Wikipediathe edition history is public and allows each modification to be reconstructed. Grokipedia under the magnifying glass The aforementioned analysis compares both platforms on a large scale and points out that, although Grokipedia publishes longer articles and with twice as many citations as Wikipediamuch of its content comes from there. Of course, the coincidence varies: pages with a Creative Commons (CC) license present very high similarities, while those generated without that license are further removed from the original. One of the most delicate issues is the appearance of references to controversial platforms. InfoWars, which according to the authors is not cited even once on Wikipedia, has 34 mentions on Grokipedia. The pattern is repeated with other low credibility domains: Stormfront reaches 42 citations, LifeSiteNews reaches 100 and the Global Research and VoltaireNet sites register 51 and 45 references respectively. All of them are practically non-existent on Wikipedia, reflecting clear differences in source selection filters. Elon Musk’s entry in Grokipedia To mention a few examples, Leiden University characterizes Stormfront as a forum associated with right-wing extremism already current neo-naziswith a founder linked to Ku Klux Klan and a trajectory mentioned in several studies for its relationship with violent incidents. PolitiFact, on the other hand, defines Infowars as a portal dedicated to conspiracy theories and run by Alex Jonesa presenter known for promoting this type of content. This is what the edition history looks like in Grokipedia What appears in the study is not limited to counting how many times these domains are cited. It also highlights that the presence of sources considered unreliable or directly discarded by Wikipedia is much more widespread in Grokipedia. And one of the authors, in a text published in Indicatorcollects this accumulation of low-quality references to describe a broader pattern: Grokipedia seems to be making its own editorial decisions that alter the focus of certain topics. It remains to be seen how Grokipedia will evolve and what publishing model it will adopt as it grows. No encyclopedia works as a perfect reference —neither Wikipedia nor Grokipedia—, but they do operate with different mechanics. As we say, Wikipedia relies on an open community with standards, public debates and an accessible history of changes; Grokipedia, on the other hand, is based on criteria that are more difficult to follow from the outside, with an AI assistant that intervenes in the texts and without a clear human collaboration system.

A new futuristic Chinese drone has just appeared on the scene. Beijing has shown it in a video without saying a single word

by

China has decided to show its new stealth drone in the most direct way possible: iincluding it in an official video and letting the image speak for itself. The device appears rolling from a hangar and forming with two J-20, a gesture that does not require subtitles to capture attention. It is an austere presentation, almost silent, but full of intention. The movement that changes reading. The official video published by the chinese air force for its 76th anniversary, it combines historical images with recent scenes, following a format that the institution has used for years. It is a simple production piece, focused on showing some of the advances that they consider relevant at this stage. Within this general route, the final section incorporates material that until now had not been seen on official channels, among them the inclusion of the GJ-11. It is a drone that belongs to the category of flying wing stealth platforms, a design that China has been researching for years and that fits with long-distance attack missions and surveillance tasks. What is known comes from sightings at test bases and analysis of their configuration, since Beijing has not published technical specifications. Some analysts interpret that its size and architecture allow prolonged flights, but that information is not part of official statements. Is it already operational? The official video does not confirm that the GJ-11 is in service, but it does fit with the indications that point to a program in an advanced phase. In recent months there have appeared at least three units in Shigatse, an active site where China tests systems in real scenarios. The inclusion of the drone in institutional material adds another element to the chronology, although by itself it is not enough to affirm that its operational deployment is a reality. The key doubts. Despite the relevance of the video, the Chinese Air Force has not offered details about the capabilities, range, sensors or weapons of the GJ-11. There is also no data on its production rate or on possible contracts associated with the program. The footage confirms its form and activity, but does not clear up technical unknowns that allow us to understand its exact role within the operational structure. The absence of this information keeps the program partially in the shadows. The appearance of the GJ-11 in an official video does not dispel all doubts, but it does consolidate an idea: China wants the drone to be part of its public story without the need to communicate technical details. Between previous indications and recent material, the image that remains is that of an advanced program that advances at its own pace.

Vigo has shown that Christmas can be a million-dollar business. So northern Portugal has decided to take note

by

Christmas is a time of peace, reunion, carols, sweets and a lot of other positive things, but also (and increasingly) of ‘pique’ between cities. As the holidays have gained appeal as an economic engine, especially for attract tourists In the middle of the low season, town councils throughout Spain have launched a race to show off the tree with the most meters, the largest display of LED lights or simply be the first to debut the ornament. Vigo is perhaps the greatest exponent of that fever, which in recent years has led him to cross challenges (more or less casual) with Madrid either Badalona. However, its true rival appears from another corner: on the other side of the Miño. Christmas in November? Christmas in November. It’s nothing new. In Vigo they began to install their lights already at the end of July, when they were missing almost 150 days for the start of the festivities. It may seem extravagant (maybe it is), but it certainly has its logic: the Galician city boasts to deploy millions and millions of LEDs along hundreds of streets (12 million in 460 neighborhoods this year), which requires a notable logistical effort. Also a substantial investment. Other cities like Madrid, Badalona, Malaga either Cadiz (to cite a few examples), determined to stand out on the map of national Christmas decorations. In fact, a quick review of the newspaper archive comes to find cross challenges between the mayors of Madrid, Badalona or Vigo on account of the festivities. The objective: to claim itself as the city with the brightest offer (literally). Why’s that? For various reasons ranging from pure economics to politics. After all, Christmas offers a showcase of brilliance barbaric for municipal administrations. If there is one reason that has become more evident over the years, however, it is tourism promotion. It is no longer just a matter of decorations encouraging purchases or more or less boosting commerce. No. Having many lights, large XXXL trees, Ferris wheels, markets… has become an effective hook to attract visitors in the middle of winter. Vigo once again leaves a good example. In December 2012, before the lighting boom, its hotels recorded just 33,600 overnight stays, far from the 100,000 in August. In 2022, already in the midst of the Christmas frenzy, this figure exceeded 101,500 overnight stays. And that’s not just visits, it’s also hard euros. In July the mayor of the town, Abel Caballero, spoke that Christmas attracts some 6.3 million visitors to Vigo and generates an economic return for the city of “more than 800 million euros”. May or may not be suspicious of those figures, but something is undeniable: the city fills every year between November and January and merchants and hoteliers already they have made it clear your support for Christmas. Which city is ahead? The battle between cities is not just about seeing which one achieves the most spectacular display of lights or raises the tallest tree. Another detail that generates expectation are the dates: Which city turns on its lights first? Which one comes forward, in an attempt to be the first to catch the eager Christmas visitors? It may sound strange again, but little by little this struggle has brought forward the festivities until placing its ‘start’ (at least unofficially) in the first half of November, almost immediately after Halloween. In Estepa, a town in the province of Seville, they debuted their lights last friday. Yes, November 7th. This urgency theoretically makes it the first municipality in Spain to activate the Christmas lighting. It won’t take long for other cities to follow in their wake. In Vigo (rain permitting) a ceremony will be held this Friday (November 15) to mark the beginning of the festivities. In other cities you will have to wait longer: Madrid either Barcelona They will press their ‘red button’ the 22ndin Badajoz it will be the 27th and in Malaga the traditional light and music show on Larios Street will also be at the end of the month, on Friday the 28th. What happens in Portugal? The most curious thing is that Vigo’s competition will probably not come from other Spanish cities, but from the other side of the Miño: from the north of Portugal. The neighboring country shares an extensive Christmas tradition and seems determined not to give up the tourist wealth that its Galician neighbor is fighting for. reveals it Vigo Lighthouse in an article in which he explains that near Raia there are towns that this year will surpass Vigo both in dates and in ‘meters’. In Valongo they opened their lights on Friday the 7th. And the next day Ermesinde, one of their parishesalso activated a Christmas tree 55 meters high, the largest in Portugal. With that data it even surpasses that of Vigo, which reaches 45 m. Another early riser town in northern Portugal is Viana do Castelowhich has a light show on one of its main avenues. Viana do Castelo and Valongo share an interesting characteristic, in addition to their Christmas zeal: they are close to Vigo. From Ermesinde it takes about an hour and a half by car. Something less if visitors travel from Viana. Simple coincidence? The commitment of northern Portugal is better understood if one knows a fundamental fact: a large part of the tourists that Vigo receives during Christmas come precisely from Portugal. In fact, in December it is not unusual to find buses in the center loaded with visitors from the neighboring country. So much so that Vigo presume of being the main Christmas destination for the Portuguese, which in turn acts as the main foreign market of the campaign. Although the Galician city has advertised your Christmas United Kingdom, Italy or France, the proximity makes Portugal its great fishing ground for visitors. “Portugal discovered Christmas in Vigo. The city was Portugal’s favorite destination at Christmas. More than Madrid and Barcelona. In 2019 we were eighth, now the first. It is a very important qualitative leap,” … Read more

Character.AI has just shown ChatGPT the way to tackle the problem of AI and minors

by

The suicide of a teenager and other cases of delusions have put AI chatbots in the spotlight for their effects on mental healthespecially that of the youngest. ChatGPT has already implemented parental controls in response to this growing concern and a few days ago they admitted to being aware that ChatGPT was causing serious mental health problems for some users. . Now, Character.ai, one of the chatbots that is also at the center of the controversyhas made a drastic decision. +18. United States already is legislating to regulate the use of so-called ‘AI companions’ in minors and Character.ai has gone ahead by taking a more drastic measure than parental control. As they say in TechCrunchStarting on November 25, the app will begin limiting the usage time to two hours for those under 18. Little by little, that time will be reduced until it is zero. Age verification. To ensure that those under 18 can no longer use the app, Character.ai is going to deploy an age verification system that analyzes user behavior. If it fails, the app will use additional identity verification and facial recognition to block users who are not of legal age. ChatGPT, warm up as you go out. OpenAI has recently taken steps to prevent cases like that of Adam Rainemainly the integration of parental control in ChatGPT. The measure contrasts with Altman’s statements days later, when he said that ChatGPT would allow us to have conversations with erotic contentbut only for adults. Altman said that the app would require age verification for anyone who wanted to use it, but he did not say anything about blocking it completely to minors as Character.ai has done. Shot in the foot? Making ChatGPT an app for people over 18 years of age would be a strong measure to end the problem or, at least, comply with what the regulations ask for. first laws that want to regulate ‘AI companions’. However, it could be shooting themselves in the foot because it would cause them to lose a lot of users, something that cannot be afforded in the current climate. OpenAI recently published a in-depth report on your usersbut did not share the data of users under 18 years of age, according to them for privacy reasons. We know that almost half (46%) of their total user base are between 18 and 26 years old. That is, a large part of them are very young users. Minors and AI. OpenAI does not want to tell us how many minors use its chatbot, but thanks to other studies we know that the use of generative AI is very popular among this age segment. According to a International Plan studyin Spain 86% of young people between 12 and 21 years old have recently used AI. In turn, 18% of girls and 12% of boys admit to using it “to talk and tell their things.” Image | Character.ai, Pexels In Xataka | The great paradox of cell phones in adolescence: they are bad for performance and mental health, but banning them at school does not help

We thought two-step authentication apps were secure. Researchers have shown how easy it is to hack them

by

The two-step verification With authentication apps it is one of the safest methods to protect our accounts, or so we thought. They count in Ars Technica that a group of researchers from several American universities have discovered a new type of attack on Android that is capable of copying these codes in less than 30 seconds, which is precisely the time it takes to refresh. Pixnapping. It is the name of this new attack capable of stealing two-step authentication codes from apps such as Google Authenticator or Microsoft Authenticator. These apps show codes that are automatically refreshed every 30 seconds, so it is more secure than, for example, SMS verification, which usually gives a margin of 10 or 15 minutes to copy the code. With this technique, researchers have managed to crack the six-digit code in just 23 seconds, which leaves plenty of time to use the code and log in to the account they want to steal. How it works. Any app on Android can launch a pixnapping attack without needing to obtain special permissions. Once underway, the attack occurs in three steps: The malicious app uses Android APIs to communicate with the app it wants to spy on. These calls force the target app to display specific data (the authentication codes) and send this information to the Android rendering pipeline, which is responsible for displaying each app’s pixels on the screen. Pixnapping performs graphical operations on the pixels that have been received by the rendering pipeline. Identify the coordinates of each pixel of interest and check if the color is white or non-white. White pixels take less time to render than non-white pixels. By measuring time, pixnapping is able to reconstruct images from the render pipeline data. Speed ​​is key. Pixnapping can also obtain other types of information that is visible on the screen, such as account numbers or personal information, but the speed with which it runs makes it especially dangerous for these authentication apps. To achieve this, the researchers reduced the number of samples per pixel, so that they could decipher all six digits in 30 seconds. Which phones does it affect? As we said, pixnapping only affects the Android operating system, but it seems to extend to quite a few versions. The investigation verified that the attack could be carried out on devices with versions from Android 13 to Android 16. They have only reproduced it on Pixel phones and a Samsung Galaxy S25, but they believe that due to the mechanism of the attack, any Android will be affected. How to protect yourself. Waiting for now. Google has already released a patch does little to mitigate this attack, but they have found that there are ways to bypass it. In statements to The RegisterGoogle confirmed that they would release a second patch in December to put an end to it. The good news is that they say they have no evidence that there are apps taking advantage of this vulnerability. Image | Pixnapping In Xataka | One click and goodbye to our passwords.
