We will have to wait to test the future with the Meta Ray-Ban Display outside the US: they are being victims of their own success

by

The Meta Ray-Ban Display are not perfect glasses nor do they pretend to be, but it’s hard not to feel that there is something different here. The idea of ​​having a color screen integrated into the lens, with speakers, microphones, cameras and even artificial intelligence, continues to sound more like a prototype than an everyday product. And yet, it is happening. Faced with other attempts to “kill” the smartphone that fell by the wayside, such as the AI Pinthese glasses aim for something more subtle. Screen on the lens, bracelet on the wrist. Beyond the concept, the Meta Ray-Ban Display is based on an unusual combination. The information appears on a small color screen located outside the axis of vision, designed for brief and non-continuous consultations. The control is not done by touching the glasses, but through the Meta Neural Banda bracelet that interprets muscle signals in the wrist area to execute minimal gestures. Meta presents this system as a more natural way to interact, reducing the need for buttons, touch surfaces or visible commands. Overwhelmed demand, expansion on pause. As explained this Tuesday by the companythe volume of interest has far exceeded the available inventory, to the point of generating waiting lists that extend well into 2026. Given this scenario, Meta has chosen to freeze the international deployment that it had planned in the short term and focus all its efforts on fulfilling orders already placed in the United States, while reviewing its availability strategy. This stoppage directly affects the plans communicated months ago. The company had indicated that the Ray-Ban Display would arrive in early 2026 in markets such as the United Kingdom, France, Italy and Canada, a first wave outside the United States that is now on hold. Meta does not speak of cancellation or set new dates, a prudent position that confirms the immediate stop, but does not clarify how long it will be extended. {“videoId”:”x9qouiu”,”autoplay”:false,”title”:”Ray-Ban Meta (Gen 2)”, “tag”:”Meta”, “duration”:”134″} Does the queue get longer here too? Although Spain was not in that first group of countries, the slowdown has obvious consequences for this side of the map. In launches of this type, expansion usually proceeds in waves, starting with the United States and continuing, in some cases, through key markets. In this case, Meta never confirmed plans for Spain, neither for this first generation nor for possible subsequent ones. The only thing that can be stated is that, if at some point these glasses end up reaching this market, the international delay makes it reasonable to think of an even longer wait. In Xataka Meta is so serious about smart glasses that its catalog is already a mess: this is how the new models differentiate themselves News for the Meta Ray-Ban Display. The stoppage in expansion has not prevented Meta from continuing to show progress. During CES, the company presented new functions designed to expand the uses of glasses, as a teleprompter mode to read prepared texts or possibility of writing messages by drawing letters with your finger on any surface, which are then transcribed into digital format. They are improvements that reinforce the idea of ​​a product in continuous evolution, even when its availability remains limited by supply and inventory.

Someone at Harvard suggested that 3I/ATLAS was an alien ship. A new test has revealed to us what it really is

by

Without a doubt one of the space objects that has been causing the most sensation in recent months is 3I/ATLAS. Practically everything has been said in recent months, from the fact that it is a simple asteroid that was going to destroy our planet to the fact that it was an alien shipas noted a professor from the prestigious Harvard. But all these ideas have been left in nothing thanks to the last signal that has been interpreted from this object. What he imagined. Interstellar object 3I/ATLAS, the third such visitor ever detected, has kept the scientific community (and science fiction fans) in suspense since its discovery in July. The most “far-fetched” speculations, as experts have described them, went so far as to suggest that it could be an extraterrestrial spacecraft, especially when it temporarily disappeared behind the Sun. The sign that explains everything. On October 24, the radio telescope MeerKAT In South Africa, a powerful network of 64 antennas captured the key evidence. This was neither an encrypted message nor a technological transmission from another species, but rather an absorption radio signal caused by hydroxyl molecules. What does it mean. Hydroxyl molecules are the direct result of the ‘breaking’ of a water molecule. This is something that happens when the ice in the nucleus of a comet approaches the Sun and sublimates due to the large amount of energy it absorbs. That is, it automatically goes from solid to gas and this is what we have detected from Earth, as has explained Michael Küppers, scientist at the European Space Agency (ESA). In summary, we are talking about 3I/ATLAS containing ice inside, as happens in comets (and not in extraterrestrial spacecraft). And we are completely sure of this, since these absorption signals are like the molecular DNI, it is unique for each compound. Goodbye speculation. As we have mentioned before, the alien ship theory gained traction when the object hid behind the Sun. Some speculated that it was maneuvering or hiding from our radars. However, on November 4, 3I/ATLAS reappeared exactly where orbital calculations predicted it would be. There were no maneuvers, just physics. Furthermore, it is not the first time it has been detected. Javier Peralta, an expert in planetary atmospheres, recalls that NASA’s Swift space telescope had already observed hydroxyl in the ultraviolet spectrum. MeerKAT’s new detection is crucial because it confirms the same composition in a completely different band of the electromagnetic spectrum: radio. What does the future hold for us? 3I/ATLAS is the third known interstellar visitor, after 1I/’Oumuamua in 2017 and 2I/Borisov in 2019. Although its trajectory is too long and it has traveled too long to know which star it comes from. But the important thing is that we are already preparing for what is coming. ESA’s JUICE mission, currently en route to Jupiter, will take new radio measurements from 3I/ATLAS in February 2026. But the big bet is the mission ESA Comet Interceptorwhich will be launched around 2029 and will wait for the next large comet to approach our planet.

Waymo lands in the great litmus test of its cars

by

Hello, London! With a simple and straightforward message, Waymo has confirmed that next year it wants to operate its driverless robotaxis in the city of London. For now, the company has to work with the authorities to win their favor if it wants to have full availability next year. It is a litmus test for fully autonomous driving in Europe. What is already known. Although it has been reported in numerous media outlets that Waymo will offer driverless trips next year, the truth is that this is not entirely the case. What Waymo has announced It is their intention to be able to offer this service but first they have to gain the trust of the regulators. For now, the company that was born from a spin-off of Google’s autonomous car will begin to operate with a human behind the wheel in specific spaces within the city. Once you obtain approval from the authorities, you will be able to offer this service to citizens. Why London? Waymo’s choice of London is no coincidence. It is not even the only company that aspires to put fully autonomous cars on the streets in the English city. Uber and Lyft They also have their own plans. If London ends up giving the go-ahead to any of these companies, it will be the first city in Europe to allow this service. The announcements have been coming in cascade since last June It will be confirmed that the United Kingdom aspires to allow these services from the spring of 2026. The British Department of Transport has advanced the deadlines by one year and they hope that in 2027 the services can be active throughout the country. A trial by fire. Although up to three companies have already shown their intention to put their cars on the street, what we will see in London will be the confirmation of whether the technology is mature enough so that cars circulate correctly in European cities. London, like many European cities, did not plan the center of its cities that date back to the Middle Ages. The network of narrow streets, complex intersections, roundabouts and a greater number of pedestrians is a challenge for robotaxis that must be able to process an almost unimaginable number of variables in real time. And the variety of scenarios and dangers that any car faces in the center of European cities has been presented as the main obstacle for companies that intend to put their robotaxis on the streets but also for companies like Tesla that aspire to have its most advanced autonomous driving systems. With leaden feet. Although the United Kingdom has its own plans, the truth is that Europe has been cautious in the field of autonomous driving. At the moment, only Mercedes has permission to circulate without the driver paying attention to what is in front of them. Of course, on previously mapped roads, with good lighting and a maximum of 60 km/h. That is to say, the system is as expensive as it is slow. The other actor that leads the way is Ford. The North American company has permission for its drivers circulate without hands in the United Kingdom and over thousands of kilometers within the European Union. Of course, the roads must be previously mapped and the driver must be able to take control immediately if the situation requires it. Companies, however, have been pressing for some time for Europe to expedite a regulation that never seems to come. The most active has been Tesla, which has published videos showing cars with the Full Self Driving activated to circulate completely autonomously in spaces as complicated as Rome either Paris. The security. The big problem that companies face is security. Waymo claims that its cars are 78% less likely to suffer an accident with injuries than a human. And the website where they announce their intentions in London it is a continuous reference to its security systems. The great obstacle for companies is to convince that this is true because when a vehicle of this type plays a leading role in an accident with fatalities, it generates more distrust than if the vehicle is driven by a human being. It must be taken into account that the autonomous car has to coexist with the decisions of other human beings, so the consequences, in part, of an accident may escape their control. To this we must add that the vehicle must understand without errors what it should do at all times. This can be a significant obstacle when a computer failure occurs, a loss of connection or, simply, a new situation that had never been contemplated. In San Francisco, for example, Cruise cars have been accused of hinder emergency services. What’s at stake? According to the most optimistic perspectives, a business close to 600 billion dollars in less than a decade for driving. autonomous (including the possible services that manufacturers incorporate to their individual clients. It is the great hope for companies that have already burned tens of billions of dollars. Obviously, the business is in a drastic reduction in operational costs which puts human drivers at risk. For now, in Guardian They report that taxi drivers have received the news with skepticism, pointing out that Waymo’s service in the United States is more like a tourist attraction than just another mobility alternative.

WhatsApp will test a way to punish those who insist without a response

by

WhatsApp has been part of our routine for years. It is one of the first applications that we install when changing mobile phones and the one that we use the most to keep in touch with family, friends or co-workers. What started as a simple channel for personal messages has become a much broader space, where groups, communities and companies coexist. Today, between notifications and pending conversations, it is common for us to receive messages that we did not even expect or from people we do not know. As WhatsApp has grown, so has the feeling of overflow. The conversations multiply and, among them, more and more messages that are not of our interest sneak in. From announcements to service reminders. For many users, distinguishing what is important has become a constant task. That scenario has led the company to explore new ways to limit abusive shipments and regain some of the lost control. New message limit. As confirmed by the companyis testing a feature that restricts how many messages can be sent to contacts who don’t reply. In practice, this means that both users and companies will have a maximum monthly number of attempts before they are unable to continue writing. The counter is only reset when the recipient responds. With this, WhatsApp seeks to stop spam without affecting normal personal conversations. Notice within the app. TechCrunch notes that When a user or company is close to reaching the monthly limit, WhatsApp will show a notification with the exact number of messages sent to contacts who have not responded. The notice appears in a pop-up box that acts as a reminder to avoid temporary blocks. The company has not yet specified what the exact limit is, as it is testing different values ​​before implementing it definitively. Test in several countries. WhatsApp has confirmed this test will be active in several countries in the coming weeks. The company insists that most users will not notice changes, since the cap is designed for those who send mass messages or do not receive a response. In principle, the measure seeks to affect only behaviors considered abusive, not the daily use of the application. The new limit is not an isolated movement. Over the last year, WhatsApp has launched various tests to stop abuses on its platform. In July 2024, it began experimenting with limits on the number of marketing messages a company can send per month. It has also extended caps on broadcast lists and bulk messages. Doubts to resolve. As we say, WhatsApp has not revealed the exact number of messages allowed or how long the test phase will last. Nor has it detailed whether the limit will be the same for individual users and business accounts. Meta is testing different values ​​and seeing how it affects user behavior before deciding on its final implementation. In the end, many of us know what it’s like to open the application and find several pending messages. Some matter, others we don’t even know where they come from. The test will tell if you really manage to put a stop to excess without complicating daily conversation.

Apple maintains strong control even on third -party stores. The test is the elimination of Ititorrent in Altstore Pal

by

IPhone and iPad users in the European Union can do something unpublished in the rest of the world: Install alternative application stores and download apps directly from the developer website. This opening was not born from a change of philosophy in Apple, but of the obligation to fulfill the Digital Markets Law. The company has always defended its closed ecosystem and has warned that opening the door to external applications compromises security of users. However, it should not be confused: even in this new scenario, Apple maintains strong control about everything that is installed on its devices. The recent disappearance of Iitorrent in ALTSTORE PAL It is the clearest proof. Ititorrent is a Bittorrent customer for iOS who had found a distribution channel out of the App Store. Everything changed when his developer communicated in Github that Apple had removed the ability to distribute the application through that route. From one day to another, Iitorrent ceased to be available for new facilities and users began to point out that they could no longer download it. What happened was not a simple technical failure: Apple had revoked the authorization that allows developers to take their apps to alternative stores, a reminder that the company still has the last word even when it is not about its own store. This is how Apple decides which applications are still alive in iOS That same system of Notarizationwhich is presented as a security review, is also the tool with which Apple retains control. If an application stops fulfilling its criteria or if the company classifies it as malicious software, can prevent it from being installed and even block its execution in the devices where it was already. The same goes for third -party stores: they depend on specific permits that Apple grants and can revoke at any time, which would mean leaving all its users without catalog. In practice, although the installation is done from an alternative marketplace or from the web, each step is still subject to the final validation of Apple, as indicated on its website. Notarization for iOS and Ipados apps is a basic review that applies to all apps, regardless of their distribution channel, and focuses on the security and privacy policies of the platform, as well as maintaining the integrity of the device. As we pointed out, first the developer spoke. He reported that Apple had withdrawn from his account the ability to distribute alternative, which left Iitorrent out of Altstore Pal. He said he resorted to the official support without obtaining clear answers. Then came the official Apple position. In statements sent to 9to5MacThe company said: “The certification of this application was eliminated to comply with the rules on government sanctions in various jurisdictions. We have informed the developed.” The contrast is evident: on the one hand, a surprised developer; On the other, a company that insists that its obligation is to stop apps that can be risk. What happened with Ititorrent is not an isolated fact. Some projects that aspired to reach alternative stores found themselves before with the rejection of notarization. For example, Mini Vmac was rejected and never arrived at Altstore Pal. What is clear is that the company retains the ability to remove apps from the circulation beyond its own store. For some users, the practice reflects an excess of control; For others, it is the way to keep your devices safe. In any case, the European opening does not in any case eliminate the central role of Apple in the process. The first question that many are asked is evident: Can Apple withdraw an application even when installed from an alternative store? The answer is yes. All apps in iOS depend on the notarization and permits managed by the company itself, so that if it revokes that authorization, the application ceases to be installed automatically. The question also arises from what happens to those who already had it downloaded. In principle they can continue using it, unless Apple catalogs it as harmful, in which case the system will not let it open. It is no coincidence: in the App Store torrents have been vetoed for years, and the company has never had a simple relationship with them.

This Europe map is the test

by

There is still almost a month ahead, but the summer of 2025 will already be remembered as The fire. You have to go back three decades ago, to 1994to find a year in which the flames will devour more forest area. The fire has devastated hectares, lives have been charged, He has calcined houses and Farms and has affected natural icons such as Las Médulasin the region of El Bierzo, now dyed black. Despite the strength of all these images there is one that even more resounding the scourge of fire in Spain: The map that compares the open surface this year in our country with the burned in other nations, such as France or Italy. What happened? If we talk about forest fires, the saying that ‘a picture is worth a thousand words’ is more true than ever, although the strongest images do not always show flames, calcined trees or smoke columns. Recently The World in Maps, a community with more than 700,000 followers on Instagram, published A map of Europe in which the surface razed in several countries of the continent. And the difference from Spain with respect to some of its closest neighbors, such as Portugal, Italy or France, is overwhelming. Click on the image to go to Tweet. Why’s that? Because it shows that on August 19 in Spain more than 348,000 hectares had been burned compared to 216,200 in Portugal, the 125,400 of Romania, 65,100 of Italy or 35,600 in France. Each nation has a different extension (only quintuplica peninsular The surface from Portugal), but still the comparison is eloquent. Spain is the one that has seen carbonized more hectares, surpassing other more extensive countries from afar, Like France. Where do the data come from? The World in Maps does not need it, but its estimates correspond more or less with those of Effisthe European Forest Fire Information System, included in the Copernicus program. The graph was prepared with data a week ago and EFFIS table It is constantly updated, so that the drawing has changed slightly since then, but the differences between nations remain more or less stable. What do they show? Right now Effis speaks of 415,300 hectares in Spain, 271,000 in Portugal, 126,000 in Romania, 72,100 in Italy and 35,600 in France. Eduardo Rojas, spokesman Official College of Engineers of MontesRemember that these figures should be handled with some caution. At the moment it is only “an advance”, an area estimation affected by the flames made with satellite data but that may not correspond exactly with reality. “Not everything has burned and not everything is forest terrain, there are reservoirs, roads …”, he warns. Effis also shows that, beyond the number of hectares razed, if we talk about the percentage of national surface affected Spain It is not the worst stop. In that case, the most tragic balance has it Portugal and Chipre. But … how is the difference explained? They are more or less precise, which reflects the map of The World in Maps (and The tables of EFFIS) is the clear difference of burned surface in Spain and other countries in Europe. So the question is obvious … What is the reason for that challenge? Rojas recalls that a key factor in the case of the Iberian Peninsula is climatology. Drought and heat waves like those suffered throughout July and August “exacerbate” fires. “Meteorological severity has a huge effect and causes hectares to vary.” Spain is not in fact the only one that has suffered fires more voracious of the usual. In early August, in full heat wavesouthern France saw them with its worse forest fire since the end of the 1940s. And it is not the only one. Portugal has also dealt with a Historical scourge In their mountains. The climatic, temperature and humidity differences in the different regions of the continent are an important factor that influences the voracity of the fires. Is it the only explanation? No. Rojas remembers that “the basic problem” is really another: progressive abandonment from rural and the accumulation of biomass and weeds that, at a given time, can feed the flames. The spokesman of the College of Engineers of Montes dimiates in fact to go beyond the data of each year and assess “the trend”. And in that case what is observed is a more or less stable number of fires and the effect of the effort to reduce landfills and control agricultural burning, although they are still present in Spain. Recently the Professional College itself He pointed out as a successful model the “ancestral forest management” of the Pinares regionbetween Soria and Burgos, where despite the enormous wooded surface there are no fires as devastating as those he has suffered The triangle formed by Ourense, León or Zamora. The reason? Partly the system of “Good luck of pines” That its inhabitants apply, a method that traces its roots to the Middle Ages and allows local communities to favor the care and management of forest masses, while also reinforcing their link and feeling of belonging. Is it something expected? The answer is affirming again. Javier MadrigalMontes engineer and researcher at the Institute of Forest Sciences of the CSIC, insists on the importance of meteorology but points to “structural reasons” in the background. “It is summarized in the abandonment of forest and agricultural management in Europe, which in a climate change scenario makes a year of adverse meteorology as this is being in the Iberian Peninsula we have broken surface records burned since 1994,” slides: “This trend was predicted by all models.” “The one in different parts of the Mediterranean is a cyclical process that depends on the meteorology,” abounds the ICF-CSIC expert, who remembers that already There are studies which show that the fire regime is not the same in different Mediterranean countries. “At country scale, the meteorological reasons more influence than socioeconomic, also seeing very aggressive fire regimes in Algeria, Greece and Türkiye, for example,” he concludes.

It is a fire test for your update policy

by

All manufacturers have a huge challenge ahead: offer a minimum of five years of updates. It is a European policy that applies to everyone equally and that, however, has a small print: five years of updates is not the same as five years of major updates. That is why Samsung’s last movement is striking with his New Galaxy A17a low -end terminal that not only complies with European law, but goes one step further offering six years of operating system updates. And that is a fire test. About the mobile. It is an entry range terminal with four or eight Gigas of RAM, 128 or 256 GB of internal storage, a processor Exynos 1330 For the 5G model and a Mediatek Helio G99 For the 4G model. The exynos dates from 2023, while the Helio G99 began to see it in 2022. In other words, they are somewhat old components and with little power whose objective is to maintain the relatively low price: 230 euros For the 4/128 GB version and 309 euros For 8/256 GB. Thus samsung money earns: the secret is on the iPhone Samsung Galaxy A17 5g | Image: Mediamarkt The software issue. It is where the crumb is. The device is launched with one UI 7 based on Android 15 and an ambitious promise: six years of operating system updates. That is, who bought this device aspires to try Android 21. This is something that, to date, was only possible in high -end mobiles. The difference is evident: a high -end mobile as the Z fold7 It has an engine with power more than enough to endure what they throw for a long time. The Galaxy A17 is another story. The challenge. Updating a mobile is not pressing a button. It is a work that requires precise optimizations adapted to the hardware of each terminal. In addition, it is a job that will have to be done in more devices, since the Galaxy A17 5G of 2025 surely follows the Galaxy A17 (or A18) of 2026, the one of 2027, 2028, etc., which, in turn, will also have to be updated. Update devices will accumulate over the years, which will make this task even more complex This concrete model will have to add all the others that, at least in Europe, will have to update for at least five years. In this way, the Samsung of the year 2030 will be updating tropecient mobiles that not only have to receive the update, but to continue working properly. Not only have to update Android 17 to Android 18, but to do so that the terminal remains usable. Where is the challenge? In hardware. While a Snapdragon 8 Elite Or their Mediatek counterpart they have more than plenty of to endure the pull for five, six or seven years, an exynos 1330 or a Helio G99 have it more raw. It is not just that the processor already starts to fall short, but that a high -end device has faster memories (RAM LPDDR5X, UFS 4.1 memories…). In the long run, a low -end mobile, however updated it is, will begin to fall short of The constant glotton of the functions of the operating systemapps and games that, update after updating, demand more resources. Samsung Galaxy A17 5g | Image: Mediamarkt The fire test. The Galaxy A17 is, therefore, a device that is worth not losing sight. Not because of the device itself, but to see how a terminal of these characteristics evolves by being exposed to an ambitious update policy that, to date, only applied to the high -end terminals. Because remember: Samsung promises six years of operating system updates, while the EU demands a minimum of five years of dry updates. They do not specify that there are five Android jumps. What Samsung puts on the table is much more juicy. The promise. Anyway, we cannot forget that this promise to offer five, six or seven years of Android updates is quite new. And above all, it is still about to fulfill. Removing Apple and Google, whose update policies speak for themselves, the rest of the brands have much to demonstrate. Samsung He started offering seven years of updates from the Galaxy S24. Honor the same from Magic7 Pro Honor. Xiaomi promises Six years From the Xiaomi 15. Motorola five years From the EDGE 50 PRO. Oppo and Realme, on the other hand, four years in some of its most powerful mobiles. We cannot analyze this now, a year after these ads. We will have to do with this in 2029, 2030 and 2031. It will be then when we leave doubts and we will see whether or not the promise are fulfilling not only in the high range, but in the low and medium range.

California will test a “co -pilot of AI” at one of the most sensitive points of its electricity grid. Can go very well … or very bad

by

There is a less visible part of the electricity grid: the one that goes out on purpose. From time to time, whole teams must disconnect by maintenance. They are routine tasks, but their coordination and validation are decisive so that the system continues to work. In California, that work falls to the California Independent System Operator (Caiso) human team. Now, an artificial intelligence will begin to collaborate with them. Caiso has launched A pilot project with the firm Oati. The objective is to verify how a language model, similar to the one that drives Chatgptcan attend in a critical mission: manage requests – especially the scheduled – that come daily to perform maintenance in the network. Artificial intelligence to attend a task that cannot fail Many of these requests imply, although not always, temporarily disconnect key assets. If the information is incomplete or incorrect, the consequences can be felt in real time: from Network instability even alterations in the electricity market. Therefore, although part of the flow is already automated, the final review remains manual and exhaustive. Between 2020 and 2025, internal graphs show a high volume of applications, with clear spring and autumn peaks, the usual maintenance windows. That seasonality, added to the total number of requests, converts maintenance management into one of the most complex operating challenges in the system. The tool is called Oati Genie and is raised as a co -pilot of AI. Detect anomalies, extract operational information and suggest steps based on previous cases. To achieve this, it combines retrieval-augmented generation (RAG) with a system of multiple agents: operators formulate questions in natural language and receive contextualized answers, with links to documents and records that support them. The operator can, for example, ask what work could affect a certain electric route and obtain a history, procedures and public data such as those of OASIS (Open Access Same-Time Information System), the regulated base that centralizes technical and market information in real time. That consultation, which previously demanded manual searches, now comes with much more agility. The co -pilot does not decide for itself, its role serves to reinforce and expedite the human decision. If everything is going as planned, the tool will enter internal tests before the end of the year. Those who use it may report failures, limitations or improvements and help profile their evolution. It is not an isolated experiment, but part of a broader strategy to Apply to other areas of the system. The plan is underway, but there is still knowing if Oati Genie will fulfill what he promises. It may become a daily ally for operators; Maybe it’s just a step on the road to a smarter network. The only sure thing is that the electricity sector already explores that address.

We thought that there would be no going back in the supremacy of AI. Then some kids arrived and an impossible test

by

There is a place in the world where some of the young brains meet every year brighter on the planet. Not everyone goes for the medal: some just want to solve six problems that could despair more than one doctorate. It is the International Mathematics Olympiad (IMO), a competition that demands a highly capable mind. Until now, it was a land reserved for humans. But this year, two of the most advanced artificial intelligence models – developed by Google Deepmind and Openai – decided to enter the board. They achieved the unthinkable: A gold score. Even so, something unexpected happened. A handful of students managed to overcome them. And that has revived an inevitable question: will this be the last time someone achieves it? Machines gain ground. Until now, no artificial intelligence model had reached that brand in the IMO. Deepmind had stayed at a single point in 2024 with 28/42 points. This year everything changed. His new AI – an unpublished version of Gemini Deep Think– Solved five of the six problems in natural language and within the official limit of 4 hours and 30 minutes. Openai’s prototype matched the feat: 35/42 points. Gold, finally, is also a matter of machines. Even so, both of them were blank in problem 6: 0 points. {“videoid”: “x8jpy2b”, “Autoplay”: fals, “title”: “What is behind it like chatgpt, dall-e or midjourney? | artificial intelligence”, “tag”: “Webedia-prod”, “Duration”: “1173”} They made history, but they did not win. The results sheets revealed that 26 human students exceeded the two AI. Alexander Wang, a young American, reaped his third consecutive gold with 37 points. But the brightest were read Deng and Hengye Zhang, from China, who signed perfection: 42 of 42, including the dreaded problem 6 that the machines did not solve. Problem 6 raised a 2025 × 2025 boxes. A agreement with Aops onlinein general, the task was to place rectangles – of any size, always aligned to the grid and without overlapping – so that each row and each column has exactly a free box. The question was how many rectangles are needed to get it. NATIONAL RESULTS. With 231 points, China recovered the first position of the medallero – United States obtained 216 and South Korea 203—, According to official results. His six representatives hung the gold; Two of them reached 42 points. The rest added between 35 and 40. As SCMP points outamong them is Qiming Xu, who achieved 36 points competing with cerebral palsy. Above, the Chinese team that led the medal. Below, the American team that was second Rival or tool? Research teams insist that they do not seek to replace students. Thang Luong, leader of the Deepmind project, assures the Wall Street Journal that Its model can be “a new calculator for the next generation of mathematicians.” The reality is that the qualitative leap is enormous: to need days of computation and formal language in 2024, to generate legible evidence in hours. That improvement raises a new scenario for schools and competitions. The last human victory? Alexander Wang believes that in 2026 the AI will already resolve the six exercises; Qiao Zhang sees it to fifty percent; And Thang Luong himself believes this could be the last IMO with human advantage. Not everyone is convinced. Former Midralist Junehyuk Jung – a researcher at Deepmind – argues that problems such as 6 will remain out of reach of the models “at least for a decade.” In Xataka Jensen Huang, CEO of Nvidia: "I have created more billionaires in my management team than any other CEO in the world" For now, teenagers leave with more than a medal: the certainty that, for the moment, human intelligence still resists. 2026 will say if that margin disappears or if they bend the pulse to the machines with pencil, paper and an idea that no one had planned.

Sending electricity without cables seemed to the future. Darpa has done it again, and the test has gone better than expected

What are 800 watts? More or less what a microwave consumes running at medium power. And 8.6 kilometers? It is an approximate distance between the stations of Atocha and Chamartínin Madrid. It is actually somewhat lower, but it serves to get an idea. That is the scale of Darpa’s last experiment: a system that managed to transmit real energy with a laser, in a straight line, without cables and with a receiver that turns the light into usable electricity. It may seem little, but it is not. The important thing was not the amount, but the test. And it worked. What exactly Darpa has done. The United States Advanced Defense Research Projects (Darpa) has successfully completed The first phase of a program called Power, designed to explore new ways of transmitting long distance energy. In their most recent test, carried out in New Mexico, they managed to send a laser beam that delivered about 800 watts for 30 seconds to a receiver located 8.6 kilometers. The figure is important because it exceeds the previous records: until now, the best documented result was 230 watts at 1.7 kilometers. Although the agency has not revealed how much power it was originally issued, it is known that the system was able to maintain energy flow for periods even longer than those officially reported. According to those responsible for the project, it was not about demonstrating efficiency, but viability. The essential thing was to check if it was possible to build a functional system in a short time. And they did it in just three months, from the initial design to the final execution. The receiver was developed by Technc Technologies and uses commercial solar cells already available in the market. The objective was not to optimize performance to the maximum, but to prove that this technology can be launched with accessible components and without complex manufacturing processes. How this technology works. The idea behind the experiment is simple to understand, although technically complex: send energy through the air with a beam of light, and that when it arrives it can be used as electricity. The DARPA system is based on an infrared laser that points directly to a receiver composed of a conical mirror and solar cells. The mirror captures the ray and redirects it towards the panels, which convert light into electrical energy. Part of the equipment used during the test The interesting thing is that no exotic components or photovoltaic cells were used to measure, as in many laboratories. Commercial cells were used, ready to use, which reinforces the idea that this technology can be viable out of paper. As we say, the performance, for now, was not the priority. Receiver efficiency is around 20 %. The Power Receiver Array Demo system achieved a new record by transmitting laser energy with more power and greater scope than ever During the test, diffractive optics were also used, an unusual resource in this type of transmissions, and an integrated cooling system was implemented directly in the optical parts, manufactured with additive printing techniques. None of these innovations was scheduled at the beginning. They were solutions that arose on the march, as they faced the challenges of the experiment. Why do it with laser and not with radio waves. Transmitting long distance energy is not a new idea. For decades it has been investigated how to do it with radio or microwave waves, but these technologies have physical limitations that include their effectiveness. As IEEE points outto work, they need large antennas and systems of Beamforminga technique that allows the signal to be concentrated in one direction. The longer the distance, the greater the issuer must be, and the more difficult it is to focus the beam with precision. Compared to radio waves, the laser can focus much better: a narrow beam can be created almost without dispersion, at least in ideal conditions, According to Eric YeatmanVice President of the College of Science and Engineering of the University of Glasgow. Of course, not everything is advantages. The lasers also disperse with fog, clouds or dust. In adverse atmospheric conditions, microwaves remain more reliable. But for certain applications, especially if we talk about aerial networks or transmissions in clear environments, the laser is difficult to match. For the Power project leader in Darpa, Paul Jaffe, if it does not work with optics, it will not work in any way. What does this advance mean (and what is not). Darpa’s experiment did not solve all the challenges of wireless energy transmission. Efficiency remains low, the system is not yet prepared to operate in adverse conditions, and the transmitted power, although notable, is far from what a commercial infrastructure would need. But that was not important. The important thing was to demonstrate that technology can work outside the laboratory, with accessible components and in realistic terms.
