problem

Nvidia has just launched its missile against Intel AMD’s dominance in PCs and laptops. There is a problem: it is a slightly obsolete missile

by

In October 2025 Nvidia launched its DGX Sparka unique workstation that the company called “the world’s smallest AI supercomputer.” that machine It was actually announced in January.but it took a while to reach the market. When it finally did, it became an interesting alternative but somewhat limited in scope. That is just what the new Nvidia RTX Spark family, which will arrive, wants to change both in the form of laptops as desktop computers, and that it will do so with a fundamental difference: Windows for ARM. Hello, Windows for ARM. The golden DGX Spark were Linux-based workstations, which targeted them at a smaller audience, but with the RTX Spark, Nvidia wanted to make the big leap to the general public. These devices are based on Windows 11 for ARM, and will take advantage of all hardware and software capabilities so that this technological solution is no longer only aimed at AI enthusiasts. Of course, that will continue to be one of the segments it will target, but these systems can also be used for both creative and gaming environments. In Xataka We wanted an ideal PC to be able to experiment with local AI models. The Framework Desktop is the answer to our prayers Approximate performance: an RTX 5070. Those responsible for NVIDIA have not yet given too many specific details about what we can expect from this platform in terms of performance, but they have indicated that the performance of the GPU It is close to that of an RTX 5070 (portable version), although the exact numbers depend on the specific application or game: in some it will be a little better, in others a little worse and in others exactly the same. Yes, they have indicated that the promise is to obtain 100 FPS in 1440p gaming as reference data. Same chip, different operating system. Hardware technical specifications They are identical to those of the DGX Spark. The main data are the following: NVIDIA Grace Blackwell Architecture CPU: up to 20 Grace cores GPU: Developed in collaboration with MediaTek, up to 6,144 CUDA cores, 1 PFLOP of AI performance Unified memory: up to 128 GB LPDDR5X at 273 GB/s with NVLink at 600 GB/s But compared to the DGX Spark, we insist, the fundamental difference is that instead of using a specific Nvidia Linux distribution for these machines, here we can take advantage of Windows 11 for ARM. When AI controls your computer. During the presentation of this platform, those responsible for Nvidia talked about the absolute rise of AI agents and how this will mark a paradigm shift in the way we use our PCs and laptops. Before we did it with a mouse and keyboard, but they see a near future in which control is taken by those AI agents, with whom we will interact in a quite different way. The example is the already famous OpenClaw and Hermeswhich with the appropriate permissions can run all kinds of tasks and applications on the computer to autonomously do things for us. Six laptops initially. The Nvidia RTX Spark platform will initially be available in six devices from six different manufacturers that will rely on this technological solution from launch. ASUS, Dell, HP, Lenovo, Microsoft and MSI will have their equipment ready this fall, although at the moment there are no specific specifications or prices announced. It is possible that during Computex we will learn more details about these devices. What can we expect in autonomy. At the moment no specific data has been given about the efficiency of these devices, but Nvidia spoke of a battery life “for the whole day.” They highlight the efficiency of the GPU and in fact indicate that GPU performance will be virtually the same whether the laptop is plugged in or not. Obviously in intensive tasks and demanding games that battery will drain much more quickly. In Xataka Goodbye to the duopoly of Intel and AMD in Windows: the arrival of NVIDIA processors is imminent and brings 8 laptops under its arm The doubt of Windows for ARM. The commitment to Microsoft’s operating system is striking, but Nvidia believes that now the system is much more mature, and that both emulation and hardware support It’s much better than in the past thanks to the work that Microsoft and Nvidia have done in the months and years leading up to this launch. They talk about a “first-class experience” for the operating system, and even commented that they have worked with the developers of anti-cheat systems in video games so that this is not a problem on these computers. And also desktop computers. When Nvidia announced its DGX Spark, then similar desktop computers appeared in format that also offered that same platform. The same thing will happen with RTX Spark, and although there was hardly any data here, Nvidia did indicate that these devices will appear in the fall from Acer, Asus, Dell, Gigabyte, HP, MSI and Lenovo. {“videoId”:”x7ztphf”,”autoplay”:false,”title”:”How to know the components of your PC (RAM, Graphics, CPU…) and the state they are in”, “tag”:”webedia-prod”, “duration”:”387″} Many unknowns and certain obsolescence. There are many doubts surrounding these devices in terms of performance or price, but there is another fundamental problem: when these laptops and desktop PCs appear starting in the fall, they will do so with chips that have been on the market for a year and therefore in a certain sense are already somewhat obsolete. Competing with the Desktop Framework. The memory bandwidth is not exceptional, and for example the Framework Desktop presented in August 2025 already offered a similar configuration in that section, with up to 128 GB of LPDDR5x memory at 256 GB/s. It will be interesting to see how the RTX Spark machines perform against alternatives like this (which makes use of a “traditional” x86 Windows 11 operating system) and whether Nvidia’s ARM chip can really make a difference in an ultra-competitive market.

Festivals turned food trucks into a money-printing machine. Now they have a problem: Ozempic

by

During the marathon days of the past Coachellaone of the most important music festivals in the world where, paradoxically, music is the least important thing, an image caused a certain sensation on social networks: the total absence of lines at the food stalls. To the plethora of content generated by the festival, a showcase for social networks where only the show by Niece Carpenter and the revival by Justin Bieber caught some attention strictly musically, we had to add the “get ready with me” on Instagram and the usual parade of looks themed, generally quite unsuitable for the Californian desert. In the background a silent revolution was brewing. Because within this hyperaesthetic ecosystem there was a shadow. In the videos of many influencers and tiktokers We were able to observe a scene repeated day after day: non-existent queues to get food (even when it’s free), facing crowded lines to buy sunglasses or other accessories. For many, the reason was obvious: Ozempic. We can interpret it from irony or, on the contrary, as a clear cultural symptom that is deeper and difficult to ignore. Because, if something seems evident, it is that, in a festival where consuming aesthetics is much more important than consuming food, the Ozempic era has found its best showcase. Less hunger = less business Anyone who’s been to a festival, especially in recent times, knows what it’s like. Until recently we went with our eyes closed and our wallets open, assuming that, in addition to the increasing price of admission, we had to pay absurd amounts for a cold burger or a pad thai stale at Michelin star price. We got into the game and no one was surprised by the exorbitant prices, those 20 euros on average per plate were part of the ritual of the festival experience; but something has started to change at Coachella. To get an idea of ​​the importance of this change: the economic volume of its gastronomic industry covers more than 100 positions. Ozempic and derivatives are completely redefining the cultural codes of the last decade. Starting from the basis that each person does with their body what they consider, it is true that we were already noticing in red carpets and derivatives that curves are beginning to go out of fashion; with bloody examples because they are carried out by former standard-bearers of the movement curvy. Actresses and artists like Rebel Wilson, Barbie Ferreira either Meghan Trainor show a change in their figure that advances from photocall in photocall. Little by little this permeates society; and also leaves a side effect that someone may consider unexpected. It is not only transforming bodies but also habits and, among them, our relationship with food in spaces of mass leisure. This change in the psychological relationship that we establish with food and the hunger-suppressing effect means that this character is eliminated from the equation. hedonist and impulsive. If the desire for food ceases to exist, the key turn occurs. For years festivals were governed by a simple rule: the economic margin is not so much in the entrance, but rather in everything that happens inside. In this mechanism, food is a key element with these inflated prices, encouraging impulsive decisions in marathon days that invite consumption. This is where Ozempic has broken the model at Coachella, fully attacking that impulse. In this showcase where it seems that eating is “annoying,” a drug that controls hunger is not useful, but rather more than consistent with the environment. And yes, Coachella may not be the Cruilla or the Arenal Soundbut on a large scale what is at stake is not only what the companies can bill food trucks. What is relevant is something deeper: in an environment where excess was part of the festival attraction, a model is now beginning to prevail where control, especially of the body and image, redefines spaces designed for the opposite. Ozempic and the end of hunger The impact of this medication is such that we are no longer talking about a health phenomenon, but rather a cultural phenomenon. What began as a diabetes medication, later converted into a weight loss solution, is no longer the beauty secret of the celebrities. The pharmacological equivalent of “drinking a lot of water and sleeping eight hours” has spread with universal consumption, and with this it not only transforms bodies with their corresponding physical consequencesalso behaviors. What began as a resource for the elite is now heading towards a more affordable distribution and on a large scale. Because we are not talking about a diet, but about something much more radical, deactivating one of the most basic impulses of human behavior on a large scale, and the data begins to reflect that change. At a global level, about 46 million of people already use these medications. In the United States, the number of people without diabetes who start treatment with these drugs has grown more than 700% in just four years. Today, around 12% of adults use them, with annual growth close to 30%. This impact does not remain only in the body and, if we transfer it to the context at hand, we see that it is directly reflected in consumption; These users spend 31% less on food and drink, especially on everything associated with whim and impulse (snacks, chocolate, etc.). In Spain the trend points in the same direction, approximately 6% of households are already consumers of these treatments, thus representing an expense of 5.4 billion euros annually in food and beverages. And, again, the most relevant thing is not what you spend, but on what: this hedonistic consumption falls and basic and functional products increase. With these numbers it is logical that the conversation of “surely he has lost weight thanks to Ozempic” does not die, but it is no longer limited to celebrities like Oprah, Kelly Clarkson or the native Ibai Llanos. The same statement now slips and extends to much closer environments such as the office, the … Read more

Europe is preparing four measures to become independent from United States technology. The problem is that he doesn’t know how

by

The European Union has been ruminating for some time that depending on third parties to manage its data, its chips and its digital infrastructure is a risk that it can no longer afford, so next Wednesday, June 3, it will put on the table a package of measures to achieve its technological sovereignty (or at least, to depend less on countries like the United States or China) whose draft they have already had access to. Financial Times either Political. The sovereignty package is so ambitious that it aims to mark a before and after at the level of the RGPD and it is not something general and intangible: there are four specific measures so that vulnerabilities such as that of Nexperia don’t happen again. But the dependence on the United States is just as worrying, as the slam of the Netherlands on the purchase of Solvinity. Two concrete examples from two different countries for the same problem: European critical infrastructure is in the hands of others. The EU package of measures. Next Wednesday, technology commissioner Henna Virkkunen will present the review of two laws known as the Chips Act and the Cloud and AI Development Actin addition to an open source software strategy and a roadmap for the digitalization of the energy sector. More specifically: The cloud, tested. Audits and stress tests to discover vulnerabilities and thus anticipate a possible US blackout. Chips Act 2. The Commission imposes the power to, in an emergency, cancel semiconductor supply contracts in the event of a shortage, fine companies that hide information about their supply chain and act as a central buyer for the 27 member states, as it did with vaccines during COVID. Open source as an alternative way. The EU wants to promote European free software companies, will encourage collaboration between states and create an instrument to maintain indigenous solutions against US proprietary software. A lot of financing: 200 billion euros are needed to expand data center capacity until 2036 and another 20 billion to execute digitalization and AI plans in the energy sector. Where from? Fundamentally, attracting private investment. Why is it important. Because Europe does not manage its own data or control the core of its critical industry and this has clear and direct consequences. The old continent has already seen the wolf’s ears. A good example is the cloud: three American companies occupy 70% of the European market, according to Sinergy datacompared to a pyrrhic 15% made in Europe. These are hospitals, public administration, defense of all of Europe operating on servers where Washington rules. In terms of chips, it has already experienced it with Nexperia: the Dutch government took control of the company to prevent China from destroying it and Beijing responded by cutting off the supply of chips, which resulted in a shortage of processors and even stops in an industry as essential for the old continent as the automobile. Context. This package of measures comes with clear bases: the recommendations of the Mario Draghi’s competitiveness report of 2024 and the Competitiveness Compass of the EU and in reality it is not more bureaucracy, but a way of simplifying everything to see the objective more clearly. In fact, a year ago the European Parliament defined what he understood as technological sovereignty: “the ability to build capacity, resilience and security by reducing strategic dependencies, avoiding dependence on foreign actors and single suppliers, and safeguarding critical technologies and infrastructure.” Regarding the chip manufacturing industry, a paradigm shift is observed: we have gone from the practical “just in time” to streamline inventories seeking efficiency and low cost to manufacturing “just in case”, something that is already contemplated by both the European chip law and its American counterpart. Europe’s problem is that it arrives late and with a tiny manufacturing muscle. Yes, but. The European record invites us to take this ambitious plan with caution. The different projects to manufacture chips in the old continent have progressed unevenly, the funds from the original law were dispersed among different state projects without a common industrial strategy (for example, Germany negotiated with Intel and France with STMicroelectronics) and the reality today is that chip manufacturing conditions in Europe continue to be worse than in China, South Korea or the United States. That Europe legislates and each state goes to war on its own also applies to the cloud: the government of each state has the power to decide what to do after the relevant audits. The new package of measures starts from the same point and runs the same risks of fragmentation. On the other hand, there is the economic issue: public financing may be dispersed, but private financing for data centers is not yet assured. And finally there is a big underlying problem: Europe has laws, but it lacks a powerful and complete industrial ecosystem to achieve technological sovereignty.

Telecinco has just bought the rights to ‘El Rosco’ from ‘Pasapalabra’. The only problem is that ‘Pasapalabra’ is from Antena 3

by

Among many other things that have happened in recent years with ‘Pasapalabra’, Mediaset paid a fine of 73 million euros for broadcasting the program without having the rights, lost the program in 2019 and has been watching for six agonizing years how Antena 3 turned it into the most watched contest in Spain. Now, Telecinco announces that it has El Rosco back. The only thing missing is everything else. Back to Mediaset. This Wednesday, Mediaset España confirmed in a very brief press release (consisting, in fact, of a single sentence, which could be interpreted as that Telecinco is not yet completely clear about its plans), that it is preparing “a new program that will include El Rosco as the final and main element.” we already knew that the Supreme Court had forced Antena 3 to withdraw that test from ‘Pasapalabra’, and abundant rumors were already circulating that approximately a year and a half ago Telecinco had closed the agreement to recover the test, conditional on the courts ruling in favor of the Dutch company MC&F, owner of the rights. High hierarchies. To get an idea of ​​how coveted the Rosco is, you only have to keep one thing in mind: the new agreement between Mediaset and MC&F was negotiated directly by Alessandro SalemCEO of the audiovisual group. What Mediaset has acquired is the license to use El Rosco: the circle of letters, the dynamic of “passing the word”, the repetition of unanswered questions and the final stopwatch. What it has not acquired is ‘Pasapalabra’ in its entirety: the full format of the contest belongs to ITV, which maintains its current contract with Antena 3. That is, the new Telecinco program cannot be called ‘Pasapalabra’ nor replicate the tests prior to Rosco. The importance of Rosco. All these shenanigans to acquire a test and not a program, without a doubt, put a question on the table: what is the true drawing power of Rosco alone if it does not have the previous forty minutes that generate tension and familiarize us with the contestants. That is the task that Mediaset now has before it: to build a program of prior tests that firmly support the star challenge. The fine. Telecinco does not come to this acquisition of Rosco with the joy of teenage boyfriends. The Provincial Court of Madrid sentenced Mediaset to pay 73.2 million euros to ITV for broadcasting ‘Pasapalabra’ without authorization between 2012 and 2019. The figure was increased considerably over the initial calculation of 44.3 million because the court estimated that the advertising revenue generated had been higher than those calculated in the first instance. Furthermore, the resolution recognized the “carryover effect”: the indirect benefit that the contest brought to the news and to the prime time later, which increased the main compensation by another 233,134 euros for that specific concept. Delicate moment. The Rosco announcement comes at the worst time in Telecinco’s recent history. The channel closed 2025 with a 9.5% annual quotathe worst record in its history for the fourth consecutive year. December 2025 marked an 8.4% share, the worst month in the regular season of his entire career. January 2026 was even more brutal: 8.5% and its worst start to the yearbelow the aggregate of the autonomous chains. The chain has been chaining minimums since July 2025, and they have taken brutal cost cutting measures such as merge the set of Informativos Telecinco and Noticias Cuatro. How Rosco affects audiences. ‘Pasapalabra’ is the most watched daily program on Spanish television for the sixth consecutive year, with an average share of 18.3% in the 2024/2025 season and a maximum of 21.1% in June 2025. But above all, El Rosco is the mechanism that keeps the viewer glued to Antena 3 until the nightly news. And whoever reaches the news program goes to ‘El Hormiguero’. Telecinco does not have anything comparable in that segment, but El Rosco as the driving force of a new contest would be a good way to fight Antena 3 at the time of day when the largest audience drags towards the final stretch of the day. Meanwhile, Antena 3 can continue broadcasting the already recorded episodes of ‘Pasapalabra’ that include El Rosco, until they receive official notification. Hectic times are coming in the afternoons of traditional television.

The Chuwi Unibook is the $450 Windows laptop that aims to take down the MacBook Neo. The problem is not the specifications

by

The Chinese manufacturer Chuwi has given the surprise with the presentation of its Chuwi Unibook, a mid-range laptop that surprises with its price of $449 and that has undoubtedly been created to compete with the new rival to beat: the MacBook Neo from Apple. The truth is that on paper the proposal seems really attractive, but the problem is precisely that: that this computer, like all those that will soon appear based on Windows with similar specifications, will have to comply with what is important. The user experience will be everything. The MacBook Neo still has no response. The PC industry was used to not having too many concerns in the mid-range. The manufacturers had accommodated themselves and proposed proposals without much ambition, modest but functional. Then came the MacBook Neo from Apple and revolutionized the sector: For the first time it was possible to access the Cupertino laptop ecosystem and its experience for a much more affordable price. There are sacrifices to the MacBook Neo, of course, but the device’s appeal is evident to many users. Apple has the A18 Pro, Intel has Wildcat Lake. The striking thing about the MacBook Neo is that Apple demonstrated that the iPhone chip was more than enough for a mid-range laptop. To compete with it, Intel has launched a new family of low-cost processors called Wildcat Lake. These chips, made with Intel 18A photolithography, are promising, and according to some benchmarks one of their variants It is 21% more powerful than the Apple A18 Pro of the MacBook Neo. The spec sheet rocks. If we look at the pure specifications of the Chuwi Unibook, the difference is notable. The equipment is not only cheaper, but it surpasses the Apple model in almost everything. For example, it has a theoretically more powerful processor, keyboard backlighting, better connectivity and more battery. The sacrifices required by the MacBook Neo are fewer sacrifices in this equipment. On paper, the Chuwi Unibook is really promising. On paper. Source: VideoCardz Project Firefly. Intel’s Chinese division recently announced this initiative. With it, they hope to help manufacturers reduce manufacturing complexity by offering reference designs that reduce production costs. Intel has already done things like this in the past (I’m sure many of you will remember both the Centrino branding and its Ultrabook program), and the idea here is precisely to provide certain tools to manufacturers to develop more competitive models in a market. shaken by the Apple model. Manufacturers wait their turn. The launch of Intel processors from the Wildcat Lake family has caused several manufacturers to begin announcing laptops based on these chips. Lenovo is already preparing some models IdeaPad Slimand so much Asus as HP They also prepare their plays. The Chuwi Unibook seems to be just another variant of those proposals, and in all of them the specifications, although modest, seem to surpass those of the MacBook Neo. Lots of advertising, little real product. Almost all major manufacturers have shown their intention to develop mid-range laptops that compete with the MacBook Neo in that price range. The announcements have been varied, but none of them have communicated the price or availability date of these devices, probably because everyone is waiting to see how the memory crisis evolves. It is reasonable to think that the imminent Computex fair is the perfect occasion to definitively present all these proposals. But. The problem with the Chuwi Unibook, like that of other manufacturers waiting their turn, is not the specifications. The problem will be the benefits and above all the real experience that these teams offer. Windows PC manufacturers have not done well with cutting features in the past, and if that experience is not good we could witness a new phenomenon like netbooks: affordable equipment, but too limited and that ended up condemned to oblivion.

Researchers solve a problem that has been stuck for decades

by

A team from Monash University in Australia has developed an ultrathin membrane able to operate hydrogen fuel cells at 250 °C and, most surprisingly, without the need for water. This is a wall in which technology has been crossing for a long time and the discovery has been published in the journal Science Advances. Below these lines we tell you all the details. Why is it important. Hydrogen cells are one of the great promises to decarbonize transportation, heavy industry and sectors where batteries fall short. They only emit water and heat, they recharge quickly and offer autonomy comparable to gasoline. The problem is that current membranes, such as those based on Nafion (a synthetic resin), they need to be permanently hydrated so that the protons can circulate. And that forces us to operate below 80-100 °C, because at higher temperatures the water evaporates and the entire system collapses. In detail. The team, led by researchers Huanting Wang and Kaiqiang He, has built atomic-thick nanosheets made of graphene and boron nitride. Between those layers they have introduced phosphoric acid in a state that researchers call nanoconfined, where the acid is trapped in tiny spaces from which it cannot escape or evaporate, even at 250 ° C. The result It is a membrane of just 50 micrometers, named GBP, that acts as a dry highway through which protons move at high speed without depending on a single drop of water. How it works. Wang, professor in the Department of Chemical and Biological Engineering at Monash, account that “by combining proton-conducting nanosheets with nanoconfined phosphoric acid, we have developed a membrane that maintains rapid proton transport without water.” The trick is in a mechanism that the authors define as synergistic, in which protons directly pass through the hexagonal rings of graphene and boron nitride and, at the same time, jump along the network of hydrogen bonds that forms the acid confined between layers. On the other hand, He adds that this combination is what gives the membrane high conductivity and stability in dry and high temperature conditions. The figures. In laboratory tests GBP achieved a proton conductivity of 166 mS cm⁻¹ at 250 °C and a power density of 1,011 mW cm⁻² in a hydrogen-oxygen stack, well above industry reference membranes. In addition, the team kept it running for 150 hours straight at that temperature without signs of degradation. Between the lines. Working at 250°C is a game-changer on several fronts. One: The water management and humidification systems are eliminated, which in current hydrogen cars are heavy, bulky and expensive. Two: at that temperature the platinum catalyst tolerates impurities better such as carbon monoxide, which opens the door to using less pure hydrogen and, therefore, cheaper to produce. Three– Cooling the system becomes much easier, allowing for smaller radiators and lighter vehicles. Beyond the car. Although we usually focus on the hydrogen cars When we talk about this type of technology, the truth is that the potential applications go much further. GBP was also tested in direct methanol cells and performed at 502 mW cm⁻² with 16 M concentrated methanol at 250 °C. This suggests that it could be used for portable systems where hydrogen is difficult to store. In addition, the authors point to uses in data centersplanes, trains, factories and hospitals as energy backup, and other electrochemical processes such as the separation of water molecules, the reduction of carbon dioxide or the synthesis of ammonia. And now what. The next step is the usual one. And when a laboratory announces an advance like this, we have to wait until it ends up coming to fruition and its commercialization on an industrial scale is viable. If they succeed, the combination of cheaper batteries, less pure hydrogen and simpler systems could accelerate the arrival of this technology in sectors where electrification with batteries does not quite fit.

In China they want humanoid robots to do household chores. The problem is that a house is not a factory

by

For years we have seen humanoid robots do somersaults, danceppractice martial arts or move through factories with increasingly striking capabilities. The next step seems almost natural: taking them home to do the laundry, prepare a bed or support elder care. The problem is that this transition is not as direct as it seems. A factory is designed to reduce uncertainty; A home, on the other hand, is full of small exceptions. And for a robot, those exceptions can be exactly the difference between a flashy demo and a useful product. The concept. SCMP account That GigaAI has introduced the SeeLight S1 as the country’s first general-purpose home humanoid robot model, developed in collaboration with the Hubei Humanoid Robot Innovation Center and the Hubei Humanoid Robotics Industry Alliance. In images released by the company, he appears performing very recognizable tasks: cutting vegetables, frying eggs, loading a washing machine, hanging clothes, making a bed or opening curtains. The company also plans to test it for free in homes in Wuhan in the first half of 2027. A house is not an assembly line. That is the fundamental difference. In a factory, the robot can work with known references, pieces always placed in the same way and movements that are repeated thousands of times with very few variations. In a home, on the other hand, nothing guarantees that the shirt is where it was yesterday, that the chair has not moved or that a pet does not cross in front of it just when the robot is trying to complete a task. Much movement, little understanding. Xinhua itself collects an idea that helps cool down the epic of the demonstrations and that does not only affect China, but humanoid robotics in general: humanoids have greatly improved in their “cerebellum”, the part linked to control and coordination, but they still have major problems in their “brain”. In other words, they can execute complex movements, but it is difficult for them to understand what a scene means and what function each object has within it. Home is also a data problem. Now, for these systems to work better in real homes, they need to learn from real homes, but the home is precisely one of the places where it is least easy to collect data. We are not just talking about room maps, but about objects, forces, angles, routines and physical decisions that are difficult to simulate. Advances and challenges. According to NSFCthe country expected to exceed 10,000 humanoid units sold in 2025, with a year-on-year growth of 125%, and there were already pilots in industrial manufacturing, delivery, catering and services. The important nuance is that none of this automatically turns this industrial career into a successful deployment within homes: the sector itself locates the path prudently, first industry, then logistics and commercial uses, and only later the home. A future easy to imagine, difficult to materialize. The difficult part is demonstrating that this can be done usefully, safely, and at reasonable cost outside of a prepared demonstration. There is the real border. China and other countries around the world can accelerate prototypes, pilots and production, but a home does not forgive clumsiness in the same way as a controlled stage. To get home, the robot will not have to understand human life better. Images | GigaAI In Xataka | In China there are already “schools” for robots. Its objective is the same as schools for humans: to teach them to work

The problem is that anyone could look

by

Many homes with small children have installed surveillance cameras or baby monitors. They allow you to monitor the child while it sleeps and, if it cries, you can go to see what is happening in an instant. All advantages, except when the camera in question has a security flaw that gives access to anyone who can look. what has happened. Security expert and independent researcher Sammy Azdoufal discovered that Meari brand cameras (including electronic peepholes and baby monitors) were completely unprotected. By simply analyzing the Android app, Azdoufal was able to extract a unique key that gave him access to more than a million cameras spread across 118 countries. All your research is detailed in its GitHub repository. What is Meari?. Surely the brand Meari Technologies does not sound familiar to you, it is normal because it is a white label manufacturer, that is, it manufactures for other brands. As explained in The VergeMeari cameras are sold on Amazon under various brands, such as Arenti, Anran, Boifun, ieGeek, Wyze, Petcube, COCOCAM, PetTec, SV3C, Joystek, Luvion and Vimar. Doing a search on Amazon Spain we found cameras from many of these brands, some of them with thousands of positive reviews. Non-existent security. The problem was not in a specific model, but in the entire architecture; Many of these brands shared servers and sometimes even credentials, so the system did not have any type of isolation: any of these brands could access the cameras of another. Additionally, the MQTT system (a machine-to-machine messaging protocol that ran on the EMQX IoT platform) did not have adequate protections, allowing real-time viewing of what was happening in thousands of homes. He also discovered that many cameras were still using default passwords such as “admin” or “public” and what is even worse, the alert images that these cameras save (for example when they detect movement) were stored on Alibaba servers without any type of protection, accessible simply through a URL. And this was not all, he also found an unprotected internal server where he found passwords for Meari and the list of 678 employees, including their emails and telephone numbers. He didn’t need to hack anything, just know where he had to look. The answer. According to Azdoufal, they did not take him seriously until they saw that their own employees’ data was being leaked, then they began to respond to his emails and solved the main failure, cutting off access to their cameras. In a statement sent to The Verge, the company admits that “Under certain technical conditions, attackers can intercept all messages transmitted through the EMQX IoT platform without user authorization.” However, it did not answer key questions such as how many camera models were affected, whether different brands have warned users or whether the vulnerability had been previously exploited. Tensions. Azdoufal was paid more than $24,000 for finding the bugs, but it was after several weeks of negotiation in which Meari did some pretty shady things. According to the researcher, the company sent him messages with veiled threats such as that the access he had made to their servers was illegal, that they were ready to “protect his interests” and that they knew his address. The company also tried to pretend that they knew about the bugs before, publishing security bulletins with altered dates. What to do if you have a Meari camera. According to the researcher, Meari manufactures for more than 300 brands and on the official website we have not found any official list, so it is difficult to know which brands are affected. If you suspect that your camera is one of these, Azdoufal recommends unplugging it whenever you are not using it, because the problem is in the cloud and is not something you can fix yourself. Also, please note that some images may still be accessible, and if you live in the EU you can lodge a complaint with your data protection authority.

A mathematical problem had been resisting experts for more than 80 years. An AI has surpassed them all

by

In 1946 the Hungarian mathematician Paul Erdős asked a seemingly very simple question: if you place n points in the plane, how many pairs of points can be exactly at a distance 1 from each other? This dilemma is known as unit distance problem in the planeand has maintained many mathematicians who research in the field of geometry, immersed in its resolution for no less than eighty years. The classic strategy proposed by many of them to try to solve it was to resort to a square grid. They soon realized that the number of pairs at unit distance grows at least as n to the power of (1 + C/loglog(n)), where C is a positive constant that quantifies how much a particular construction can be better than a basic square grid. It’s a complicated idea, it’s true, but we can try to approach it in a slightly more intuitive way. A standard square grid produces approximately 2n pairs of points at unit distance. If we rescale it in an ingenious way by choosing the scale factor as a number that has many divisors (in number theory this property is known as a number with many small prime factors), you get more pairs of points to fall exactly at distance 1. The value of C measures precisely the efficiency of that choice. This is the key. An AI from OpenAI has achieved the first major breakthrough in 80 years As we are seeing, the question Erdős asked is very easy to state, but extraordinarily difficult to resolve. If we develop the classical approach a little further we will realize that since loglog(n) grows very slowly, the exponent approaches 0. This means that the square grid grows only slightly faster than n, but not enough to exceed n at a fixed rate. This milestone was achieved by a general-purpose inference model that OpenAI was testing internally. This is why for decades mathematicians predicted that the upper bound would be approximately n^(1+o(1)), that is, just slightly larger than n. Now we know that they were wrong, and the person who refuted this conjecture was not a particularly skilled current mathematician; this milestone has pointed it out a general purpose inference model which OpenAI was testing internally. and not one artificial intelligence (AI) specialized in mathematics. This model has provided an infinite family of examples that produce polynomial improvement. In fact, he has shown that it is possible to construct configurations of points with at least n^(1+δ) pairs at unit distance, where δ is a fixed value greater than 0 that does not disappear as n grows. When the AI ​​delivered this result, OpenAI researchers asked a group of Princeton mathematicians to review it. And his conclusion was blunt. The AI ​​was right. This is the first progress on the lower bound of the problem posed by Erdős in 80 years. And, curiously, the OpenAI model has achieved this by using advanced engineering tools. algebraic number theory for an apparently elementary geometry problem. Several renowned mathematicians, such as Fields Medal winner Tim Gowers or number theory expert Arul Shankar, have declared that the result that AI has delivered is an extraordinary achievement that could provide mathematicians with a bridge to explore other problems in the future.

Giving seven times more vitamin D during pregnancy improves children’s memory at 10 years old. The problem is in the fine print

by

During pregnancy, the recommendations of supplementation They are an area where science advances with lead feet, since the most important thing is always to guarantee safety. One of these supplements that is heard the most is vitamin Dtraditionally known for its role in calcium absorption and bone health, but which has been in the spotlight for years for its possible impact on neurodevelopment. A new study of Danish origin has put its objective on this statement to be able to clarify what happens when a mother supplements with vitamin D during pregnancy. Through its publication in JAMAtells how, to achieve good results, almost 500 children were analyzed for several years until finally being able to see if they had cognitive improvement during their childhood. What were they based on? To understand this discovery we have to go back in time to a randomized clinical trial titled as COPSAC2010whose initial results were published in 2016. This trial sought to evaluate whether vitamin D prevented the risk of suffering from asthma or persistent wheezing in babies, and to verify this the researchers divided the mothers into two groups from the 24th week of gestation: One group would receive the standard recommended dose of vitamin D of 400 IU per day. The other group had a “megadose” of vitamin D of 2,800 IU daily. The discovery. Taking advantage of this valuable group of 498 children, the research team decided to get more out of it, since when these children reached 10 years of age they were subjected to rigorous cognitive tests to see if the fact of having given vitamin D to their mother during pregnancy had left its mark on their brain. In this way, two objectives were covered with a single investigation. Here the results revealed that children in the high supplementation group showed a modest but significant improvement in verbal and visual memory compared to the children of mothers who took the standard dose of vitamin D. Although something important to note is that it puts to rest any idea that this supplementation is a machine to “create geniuses”, because there were no differences in IQ and they only saw that the ability to retain information was improved. The small print. Given such a finding, it is tempting to think that all pregnant women should multiply their vitamin D intake to give their children an advantage over others. But here we must pay attention to different problems, such as that the original trial was designed to measure respiratory problems and not neurological development. This means that drawing conclusions from here reduces the statistical robustness of the discovery. But this is not the only problem, since we have seen that the effect is “modest” without seeming to give children a great advantage. And furthermore, the study is based on women who already had normal vitamin D levels before the study, so it is not clear how this dose would act in populations that truly have some type of chronic deficiency of the vitamin. Will there be changes? At the moment, these studies do not justify the need to recommend that all pregnant women supplement their diet with vitamin D, as is the case with other supplements such as folic acid. The real value of this research is not to give us an immediate new prescription, but to open the door to future clinical trials specifically designed to unravel how what happens in the womb continues to shape our brains a decade later.
