give up the high cheap speed to Ouigo and Iro

High speed Renfe output Low Cost In Madrid-Barcelona it is the chronicle of an announced death. The company was not obtaining bad results in the corridor with the AVE but the problems with the Avril trains have removed it from the race for the price. The company renounces high speed Low Cost In this corridor. This is all that has happened. Goodbye to Madrid-Barcelona Cheap. It will be from September 8 but the decision is taken, as confirmed by The country. Renfe Saca Avlo, its high price of low price, of the corridor that moves more traffic in Spain. It is a decision that backed by the failure of their Avril trains, which had to be removed a few weeks ago in this line. The company will relocate in birds to those who buy an avlo ticket for the dates after September 7, so they will get a small Upgrade without doing any disbursement. What happened? At the end of July, Renfe paralyzed the sale of tickets of the Avlo trains in Madrid-Barcelona. The decision, which seemed surprising, soon shows its true face: the Avril trains that provided this service had suffered damage during a trip. The information was revealed by The economistwho assured that cracks had been detected in the trains. Then a pull and loosen between the media and renfe. The company began denying what happened, speaking of reorganization. Time later he confirmed that trains had suffered damage and that would circulate at a lower speed. Subsequently, Some leaked photos They demonstrated the seriousness of the damage. Finally, Renfe withdrew the Avril from the line. Because? The causes that have caused the damage to the Avril trains built by Talgo are about to be revealed. In fact, a strip and loosen between both companies have already begun to settle who takes care of the damage. Trains are under guarantee Because they delivered just over a year ago. The Avril trains were sold as a milestone of the engineering of the Spanish trains. Ra take high speed to Galicia. The latter too suffered problems with the change of year and also accumulated delays in their first days In Galicia and Asturias. But, in addition, the Avril trains have also been criticized for their Low quality in interior materials or by the Strong shakes that occur when they are in motion, far from the best European high -speed trains. In the hands of Ouigo and Iro. With the departure of the Avlo, Renfe renounces the high cheap speed. Or, at least, to a good part of it because the company ensures that it will continue to offer “Competitive prices”. However, it is difficult to think that the latter is not a specific strategy, taking into account that the Avlo seat cost an average of 37 euros, for the more than 61 euros on average of the bird, According to CNMC data. In addition, the impact of Avlo was not less on the line. It is true that Renfe had a market share of 60.1% between Madrid and Barcelona in 2024 but 12.2% of the total market share was borrowed by Avlo. That is, most passengers already moved in AVE but the Avril trains allowed them to compete in a market that will now be more complicated, with trains with less available places. The second company that has been taking over Madrid-Barcelona is Iro, which accumulated 23.7% last year, while Ouigo stayed at 16.2%. Renfe, in addition, had managed to remove customers from Ouigo because both Avlo and Iryo grew two percentage points compared to 2023. A clear bias. However, Madrid-Barcelona is a corridor marked by high prices. As we have seen, most of the travelers continue to opt for the bird despite the fact that their tickets are, on average 25 euros more expensive than those of Ouigo, always According to CNMC data. Avlo, in fact, offered cheaper tickets than those of Iro (37.8 euros compared to the 40.3 euros of the Italians). This issue had caused Ouigo itself, which offered the cheapest tickets and yet had the slightest market share, would opt for some time to remove some of its trains and boost the Andalusian corridor, more price sensitive. Now he has a new open door to insist again on the high speed Madrid-Barcelona.

Nvidia is going to give your chips to the push you need to maintain their domain

by

Nvidia is preparing to open the door to the door to The photonic silicon. Just a few hours ago it has started in Palo Alto, California (USA), the Specialized Conference in Semiconductor Engineering and High Performance Computing ‘Hot Chips’. And the company led by Jensen Huang has not let out the opportunity to announce that in 2026 its platforms of artificial intelligence (AI) latest generation They will use photonic interconnections to reach higher transfer speeds between GPU clusters. Most of the designers and manufacturers of integrated circuits are working on the development of silicon’s photonic. Douglas Yu, a TSMC executive with responsibility in the field of systems integration, explained In September 2023, what disruptive capacity has this technology: “If we manage to implement a good system of integration of silicon photonics we will trigger a new paradigm. We will probably be placed at the beginning of a new era.” Nvidia has just taught her letters Before moving forward we are interested in intuiting with some precision what we are talking about. The photonic silicon is a discipline that in the field that concerns us seeks to develop the technology of this chemical element to optimize the transformation of electrical signals into light pulses. The most obvious field of application of this innovation is the implementation of high performance links that, on paper, can be used both to solve communications between several chips and to optimize the transfer of information between several machines. Advanced packaging technologies with which the main semiconductor manufacturers work, such as TSMC, Intel or Samsung, can benefit a lot from a communication mechanism between very high performance chips. And the big data centers in which it is necessary connect a large number of machinesalso. However, there is a particular discipline that has a projection of the future overwhelming and the one that would be wonderful about the advantages proposed by the photonic silicon: AI. CPO technology reduces energy consumption to just 9 watts per port This is precisely Nvidia’s commitment. In the clusters of the thousands of GPU they must work in unison, so it is essential to connect them using high performance links. It is possible to solve this challenge using traditional copper cables or optical modules, but these two solutions introduce very important inefficiencies in the infrastructure. The most problematic are the loss of energy and bottlenecks. Data transfer can consume up to 30 watts per port, which increases the dissipation of energy in the form of heat and increases the probability of a failure. In addition, latency limits the scalability of clusters as the GPU number of data centers increases. To solve these inefficiencies NVIDIA will integrate the optical components that require photonic interconnections In the same encapsulated switching chip. This technology is known as CPO (Co-Packaged Optics) and reduce energy consumption to only 9 watts per port. In addition, it minimizes signal loss and improves data integrity. It looks really good. NVIDIA has confirmed that it will integrate CPO technology into its Quantum-X infiniband and Spectrum-X Ethernet interconnection platforms during 2026. However, there is something important that is worth not overlooking: CPO will not be an extra. When it arrives, it will be strengthened as a structural requirement of the next generation of data centers for AI in a clear attempt to increase the competitiveness of hardware platforms for NVIDIA.

Your classic search engine is blurred to give way to searches for AI

by

The transformation is underway. Millions of people around the world are seeing how a New button on Google’s home pagethat same that has marked the internet pulse for decades. It is not a secondary addition or a tab that goes unnoticed. It is the new Ai mode. With this movement, artificial intelligence becomes the protagonist of the search experience, displacing the classic formula which has defined the search engine since its origins. And with this there are changes that not only affect users: they also challenge the information industry and Google’s own business model. From the links to the answers: a jump that changes the rules Ai mode is available, for the moment, only in English, Although its global deployment has already begun. For those who press the aforementioned button, the search engine will stop functioning as until now: the consultations no longer show the lifelong links, but in responses prepared directly by the AI. The land had already prepared with the Google ai overViewsgenerated summaries that occupy the most visible part of the results page. If a couple of years ago you were looking for something like “Cafeterias in Paris with good wifi and quiet corners to work”, Google showed well positioned pagesRecommendations in blogs or forums, and some Google Maps block. Example of results with Google Ai Overviews With the Overviews the dynamics changed: before reaching the links, the user was a summary created by AI as the following: “To enjoy a modern Parisian experience with good wifi and quiet workplaces, consider X place. For its modern environment. X place It also offers a cozy atmosphere. ” Thus the tool responded, linking to the sources he had used to elaborate the generative summary. That jump placed the information processed and summarized in the foreground, but also opened a debate: AI can be wrong. His “hallucinations” They have already left uncomfortable holders, from non -existent presidents to poorly cited years. On the other hand, the impact was immediate: less traffic for content creators, less advertising impressions. And this also reaches Google, that still controls much of the advertising that is inserted in third -party sites. With that context, the launch of AI Mode is another step in this direction. Press the new button, The list of life results disappears. If we repeat the search for Parisian coffee shops, the answer is no longer limited to a contained recommendation. Now a more elaborate compendium is shown: coworking spaces, specialty coffees, interactive maps, quiet areas to work and even practical advice on how to find the best options. Example of results with Google AI Mode In the desktop version some links continue to appear in a reduced module to the right, but the message is unequivocal: Google wants you to solve everything without leaving its ecosystem. The experience is conversational. You can ask for a specific place, ask for comparatives or add nuances, and The system keeps the thread of conversationfeeding on the web to give you the answer. Google summarizes it on its official page: “Are you trying to understand a new topic? Are you looking for specific recommendations? Do you need help to decide between two products? Just ask us.” All this works with Gemini 2.5 In its standard version, although users can access Gemini 2.5 Pro Reasoning capabilities. With AI Mode and AI Overviews, Google takes a radical turn: the search ceases to be a catalog of links to become a response system. And that transition not only redefines how we find information, but opens a new chapter in The balance between the open webthe creators of content and the giant who, to a large extent, controls the entrance door to the Internet.

Plan to remove 2,000 million from the chips and give them to critical minerals

by

Donald Trump has criticized on many occasions The Chips Law approved in July 2022 by the government of Joe Biden. At the end of last January and just a week after returning to the White House, the US president He made this statement: “In the very close future we will impose tariffs on foreign production of computer chips, semiconductors and pharmaceutical products to return the manufacture of these essential goods to the US (…) went to Taiwan; now we want them to return. We do not want to give them billions of dollars in The ridiculous Biden program. They already have billions of dollars. “ “The ridiculous Biden program.” It is evident that Donald Trump doesn’t like Chips law at all. Three months before, in October 2024, I had already charged ferocity against this program of the previous administration In Joe Rogan’s podcast: “We put millions of dollars on the table so that rich companies came, they borrow the money and build chip companies here. And they will not give us the best companies.” At that time the possibility that Donald Trump dismantled the Chips program if he arrived at the government was on the table, which caused semiconductor manufacturers They were hurry to collect subsidies Before his return. The partial dismantling of the Chips Law is on the table Presumably Intel, TSMC, Globalfoundries and other designers and manufacturers of integrated circuits have already charged the subsidies of the Chips program assigned to them during the mandate of Joe Biden. Or part of these funds. A priori the money that has already been delivered will not be returned to the administration, but a part of the funds remains in the hands of the Department of Commerce, which is currently led by Howard Lutnick. AND, According to Reutersthe government is considering reallocating at least 2,000 million dollars. China is restricting the export of many of these minerals in response to US sanctions and their allies If this measure thrives those funds initially reserved for semiconductor research and the construction of chips factories will be used to finance projects dedicated to obtaining and the processing of critical minerals. At the moment China controls extraction, processing and the distribution chain of a good part of this crucial strategic resource for many industries, such as integrated circuits, telecommunications, batteries or the electric car, among others. And the country led by Xi Jinping is restricting export of many of these minerals in response to the US sanctions and their allies. The US needs to drastically reduce its dependence on critical minerals controlled by China, and the decisions that Donald Trump has made during recent months reflect clearly that he is much more worried about reinforce the American land industry to deliver subsidies to chips manufacturers. However, the reallocation of these 2,000 million dollars will have an additional effect, if it thrives, it is worth not overlooking: Howard Lutnick will expand its influence to the critical mineral sector. And this manager has the total confidence of Donald Trump.

These glasses with AI have been designed to look like a genius. They register your environment and give you all the answers

by

Imagine carrying glasses that seem normal, but that inside offer you constant and silent help. The concept sounds intriguing: without touching anything, You can solve doubts instantlyreceive a clear explanation of something that you do not understand or have an automatic translation in the middle of a talk. A startup called Halofounded by former Harvard students, has created glasses with that idea in mind. And not only that: they promise to endow us with a “superhuman intelligence.” Beyond the marketing strategy, the approach is interesting. Glasses that listen and respond in real time Halo X do not resort to cameras to dazzle us, but bet on a different approach. They are designed for Listen to what happens around youtranscribe each conversation and show on an internal screen information that they consider relevant at that time. They do not wait for them to dislike, but try to anticipate and be useful proactively. In practice, that means that if the name of a car model arises in a talk, they can show a card with key data; If a technical term appears, promise to display a clear definition. The information operation appears in front of your eyes in less than a second. Even in everyday situations, such as speaking in another language, they should be able to real time and facilitate communication without having to do anything else. Halo talks about answers around 900 milliseconds for most consultations, while the most complex searches take about two and a half seconds. To achieve this, the glasses rely on two complementary artificial intelligence engines. Geminithe Google model, is responsible for reasoning tasks, while Perplexity It works as a contextual search engine that consults information on the web. As for the hardware, the halo X bets on the discretion. Incorporate a small type display Waveguide Visible only for the user, microphone and integrated speakers, and dispense with this version. The autonomy announced is around eight hours of continuous use. Of course, they do not process everything on their own. They depend on a connected mobile phone and an application that acts as an intermediary, where most of the calculation and consultation work really runs. The great debate point is in privacy. The system records what you listen, transcribes it and, according to the company, eliminates the audio immediately after. Halo ensures that the product will arrive with end -to -end encryption and that is working to obtain the SOC 2 certification, which would imply external audits on data management. The system records what you listen, transcribes it and, according to the company, eliminates the audio immediately after. However, they do not include any visible indicator that alerts those around you that they are being recorded, and that raises reasonable doubts. The controversy is not new: the founders They had already experienced with unauthorized facial recognition systems about Meta Ray-Banwhich generated debate about security and improper uses of technology. At the moment, Halo X are not available in stores. They can be reserved on the official website with a starting price of 249 dollars And, by selecting euros in checkout, today they appear in 223.13 euros. The company has not yet offered a specific date of shipping or confirms whether there will be official distribution in Europe. It will be necessary to see if the halo X does not end up repeating the recent history of other devices that promised to revolutionize our relationship with artificial intelligence and ended up being sued fiascos. Rabbit R1 and the AI ​​Pin of Humane They aroused enthusiasm in their presentations and arrived with very ambitious speeches, but failed in practice. Halo’s ambition is on the table and his proposal is as attractive as controversial. It remains to be seen if these glasses They fulfill what they promise or if they will end up swelling the list of inventions that pointed high and stayed on the road.

The most obsessively competitive gamers have found a trick to win their rivals: Give Electric Downloads

by

Today video game developers are really strict in terms of cheating in their creations, with different systems Anti -che that They even affect kernel From our computer as is the case in ‘Valorant‘. But a new generation of Modders It is demonstrating that traps can be done without touching a single line of game code: with electrical discharges. If I can’t hack the game, I’m looking for alternatives. For some people, it is good for it is the same as Apply different tricks to games that they use daily to be able to cross walls, be immortal or have an automatic point when talking about Shooters. But this is something that leaves the rest of the players of a game. Having the player himself. Two Youtubers They have put the solution on the table to skip the barriers that are applied at the hardware level. One of them is ‘Basically Homeless’ that has led the concept of ‘player improvement’ to a new level. And instead of installing software that points for it in Counter-Strike 2, has created a system that electrocutes your arm to react at a superhuman speed. The mechanism is fascinating. An external software analyzes the screen in search of enemies. As soon as one detects one, it sends a signal to a Raspberry Piwhich in turn activates muscle stimulation diodes placed strategically in its forearm and hand. These little cramps force their muscles to get contracting, moving the mouse towards the target and clicking. Surprisingly, it is something that works. The results are very good. The own Youtuber He managed to reduce his reaction time of about 200 milliseconds approximately at only 100 milliseconds. According to its calculations, using an Ethernet cable connection instead of Wi -Fi to communicate the PC with the Raspberry Pi, it could lower this figure to 40 ms, a practically unbeatable speed for a human being. It does not consider it a trap. For this creator this is not something that threatens ethics when playing against other people. It is only a help, or as he calls it, ‘neuromuscular aim assistance’, since it is technically his own body who performs the action, although induced by a machine. Although it remains to be seen what large companies would say if this is popularized. Robotic carpets that point for you. In a similar line, the Modder Kamal Carter has presented another solution of hardware to dominate in Valorant. In his case, the protagonist is not his arm, but a robotic platform located under the mouse mat. And the system is similar. A screen reader identifies the enemy bots in the game’s shooting field in the first place. Next, a program that emulates the techniques of aimed at professional players sends instructions to the platform. This moves with a millimeter accuracy, displacing the mouse to achieve perfect shots. After adding a system that automates the click, Carter achieved almost perfect scores in practical mode. The most advanced anti-cheat systems are weak. “Made the law, made the trap,” says the saying. And in this case it is fulfilled. Large companies no longer know what to do to avoid tricks in their games, coming to ‘invade’ the kernel of our computer with maximum Windows privileges. Something that is designed to detect the use of unauthorized software. And there are many consequences that are being presented by cheating. Valve managed to block 40,000 cheats In ‘Dota 2’ or in ‘Deadlock’ They transformed into frogs to the most cheats to become aware that they should not do that. But also in Warzone they bet on Block the opening of the parachutes with the aim of crashing directly with the ground. But now these new tricks can be more difficult to detect and apply a punishment.

Japan is saturating from the hordes of foreign tourists. So in the country they have begun to give them free flights

by

Japan is filling with tourists. Only during the first half of the year added 21.5 million of foreign visitors, 21% more than during the same period of 2024. There are many. Many. Enough to he overwhelming It has become a Debate theme priority and be giving wings to the formation of extreme right Sanseitō, who managed to stand out in the July elections with the motto “Japan first”. The problem is that, far from being distributed in the country, that tide of visitors is concentrated in certain mass points. There are those who want to solve it giving flights To tourists. What happened? That Japan Airlines (JAL), one of Japan’s main airlines, has had An idea peculiar so that foreign tourism becomes more bearable to the country’s mass destinations: give tickets. Literally. The idea is that foreigners visiting Japan have free flights that encourage them to go beyond Tokyo or Osaka and explore less known corners, such as Sapporo, Naha either Hakuba. The goal is double: relieve pressure at the busiest points in the country and, incidentally, give a small push to foreigners to visit places that would never include in their itineraries. What do they propose? The first thing to clarify is that it is not a new campaign. Aviation Wire I already talked about her in October 2024but with mass tourism in the center of the debate and Japan turned into one of the most demanded destinations in the world, the campaign has gained popularity again. In recent weeks, media have talked about it as Soranews24, Time out or the specialized website Travel and Tour Worldconfirming that the initiative was launched in autumn without completion date. The idea too He has echoed in Spain. What are your details? The campaign consists of giving national flights to foreign tourists so that they can move through Japan, although (as usually happens) it has a small print. It is not available for all visitors and even those who can opt for it must meet before A series of requirements. From the entry the offer is available to users of certain countries, such as the United States, Canada, China, India, Australia, New Zealand, Taiwan, Vietnam or the Philippines, inter alia. In addition, the beneficiary travelers must reserve on their own the international round trip from their country of origin. Once in Japan it is when they can opt for one of the national tickets of JAL promotion, which must include in the same reserve. TTW precise An extra detail that demonstrates how the campaign aspires to relieve pressure in the most busy cities in the country: those visitors flying from the US, Canada, Mexico or China and decide to remain more than 24 hours in the city where they land (usually tokyo) must pay a rate of $ 100. Why is it important? Beyond the details of the campaign or if it really goes on account or not foreign tourists, Jal’s idea is interesting for another reason: it shows Japan’s attempts to make tourists’ avalanche more assumed and do not saturate its most popular destinations. That the initiative has had so much impact is also explained by who spears it: Japan Airlines is one of the main country airlines and on its website presume that your group has a total of 133 national routes and 66 international connections. This wide network of domestic connections is what intends to take advantage of foreigners explore places in the country less popular than Tokyo or the Las Geishas neighborhood of Kyoto, like ski slopes of Nisekothe reefs of Okinawathe mountains of Hakuba either Tomamu or the natural landscapes of Hearbetween a long (very long) and so on. In his favor he has the Encrying From Japan Rail Pass (JRP), which makes the plane win attractive in determining routes. So much tourism in Japan? Yes. The latest official statistics show that during the first half of the year he received 21.5 million of foreign tourists, a surprising fact for two reasons. The first, because it is a record for the country. The second, because it represents an increase of 21% with respect to the same semester of 2024, which gives an idea of the accelerated rhythm to which the sector is growing. Only in June the flow of foreign visitors grew by 7.6%. That boom has come accompanied by the arrival of Millions of dollarsbut has also submitted to the country (especially the most massive destinations) to A pressure that has electorally fed the formation of the extreme right Sanseito, which relies on A speech antituristic and antimigratory. The clearest example of that overwhelming It is located in three busy places: the Fuji, where They have started to charge a rate; The neighborhood of the Geishas de Kyoto, where They have prohibited to “paparazzi tourists”; And Fujikawaguchiko, who has had to cover his views to avoid the hordes of tourists to hunt the best Selfie. Does it work to give flights? It does not seem. As the statistics demonstrate, Japan continues to win tourists and Tokyo remains in The lists of the busiest places. The director of JapaneseLaura Tomàs, acknowledges in An interview with The confidential that the campaign also has some clear weak points. “The routes do not always fit the schedules, the information is not clearly communicated and in many cases the tourist ends up opting for the known.” Images | Matt Cramblett (UNSPLASH), Nomadic Julien (UNSPLASH) In Xataka | Japan will copy Venice to stop mass tourism.

Nvidia and AMD can sell their chips from AI to China. The amazing thing is that to achieve this they will give the US a slice of 15%

by

Nvidia and AMD have agreed to yield to the United States a part of the income from the sale of certain AI chips in China. This pact unlocks the export of these components to the Asian country after months of uncertainty, but does so with that unusual consideration. The context. The US government It has been for years imposing all kinds of prohibitions to Chips exports and advanced technology from AI to China. The goal has always been avoid that the Asian giant could compete. The shot has come absolutely for the cylinder headand the advance of Chinese AI models –As Deepseek– And chips –Like Huawei– They show that this tactic has not worked. Nvidia and its H20 chips. To try to avoid those vetoes, Nvidia He developed his H20 chip with the intention of meeting the requirements of the US government – not selling its most advanced chips – and thus continuing to obtain income in China. They didn’t even solve the problem, and the US government prohibited the sale of that chip in the Asian country. A dilemma that also involved AMD. US has faced for months A apparently impossible dilemma: to sell Hardware from AI to China, or that of not selling it to him and that they develop them. AMD was also in identical situationabsolutely blocked to be able to sell their chips from AI to China, which meant a colossal problem for their global income, which are nourished with force of sales in China. Solution: Give me my slice. What has unlocked all this scenario has been, of course, money. In an unprecedented agreement revealed In Financial Timesthe US government will allow NVIDIA and AMD MI308 to export to China, but 15% of the revenues of these sales will go to the United States government coffers. Jensen Huang had already notified. The CEO of Nvidia, Jensen Huan, already warned that the blocking of the sale of its chips in China could cause A reduction of 15,000 million dollars In your income this year. The Asian giant represents 13% of the total income of Nvidia, but The sanctions They threatened the survival of this company (and AMD) in that country. A successful meeting. According to FT, the US Department of Commerce began to issue export licenses for the H20 Chips on Friday, two days after the NVIDIA CEO met with the US President Donald Trump. That meeting seems to have been the definitive After the theoretical initial agreement that both had reached less than a month ago. This had never happened. This “Quid Pro quo” is not preceded, FT analysts stand out, who point out that no US company had previously agreed to pay part of their income to obtain export licenses for their products. Even so, the pact follows the dictatorial position of President Trump, which In addition to its badly called reciprocal tariffs Does not to demand that companies manufacture the chips used in products that are sold there in the US, such as iPhone. The forecasts. According to analysts of the consultant Bersntein, Nvidia would have sold about 1.5 million H20 chips in China without exports controls. That would have meant revenues of about 23,000 million dollars, but now that figure is probably lower. Even so, it is expected that Chinese companies make great orders of both the Nvidia and AMD chips. A worrying precedent. Meanwhile, certain experts criticize this type of agreement. Liza Tobin, of the Jamestown Foundation, commented on how “Beijing must be gloating to see how Washington converts export licenses into sources of income. What will be the next one? Let Lockheed Martin sell F-35 to China in exchange for a 15 %commission?”. Image | Nvidia | Dominic Kurniawan In Xataka | China’s first avant -garde lithography machine is not the biggest US problem.

His new mode does not give the answer, he builds it with you

by

A frequent criticism among many teachers – and also among students – is that Chatgpt tends to offer direct answers to any consultation. Even assuming they are correct –We know that AI models can still hallucinate-, the user gets the solution without having traveled the path that leads to it. There are ways to guide the model through Prompts to avoid that immediate response and make it an ally of learning. But that additional effort does not always compensate. And in practice, if there is no more direct alternative, many choose not to use it. That alternative has just arrived. It is called “study mode” and its proposal is clear: help you learn, not just to answer. What is the chatgpt study mode Chatgpt was already a very popular tool among students. But his usefulness in learning had always been in question: Is it used to learn or only to solve tasks? He Study mode It was born precisely to answer that question. From today, the users of the Free plans, Plus, Pro and Team can access this new way of using chatgpt: an experience that does not directly deliver the solution, but accompanies the user to it. A change of approach that wants to leave behind the “do my homework” and get closer to “Explain how it is done.” According to OpenAithe study mode is designed to guide the user instead of giving the answer directly. They do so, they explain, through orientative questions, clues and a clearer structure that facilitates step by step learning. They also ensure that the system adapts its behavior based on the level of the user and its objectives. The answers are divided into understandable blocks, with less information saturation and more context when necessary. All that, without losing flexibility: it can be activated or deactivated at any time. The mode of study has not come out of nowhere. The company led by Sam Altman assures that you have worked with teachers, pedagogues and experts In learning science to define how the system should behave in educational contexts. The intention, they say, is that the model not only resolves doubts, but does so that it reinforces understanding. To achieve this, they have been based on principles such as active participation, self -reflection, cognitive load management, the promotion of curiosity or the use of comments oriented to improvement. How to use and what have we met To activate the study mode, it is enough to open chatgpt and select the “Study and Learn” option in the tools menu. From there, you can launch any questions related to duties, preparation of exams or topics that you want to understand better. The system automatically adjusts and changes its way of responding. In our tests, for example, we ask for help to solve a statistics problem. Instead of giving us the solution, The model began asking simple questionsoffering small clues and asking us to make calculations. The answer did not come suddenly, but step by step, as if a tutor guided the process. This behavior can be seen in the following captures: first the consultation, then the reaction of the system, and finally the invitation to which we solve part of the problem on our own. This is just the beginning For now, the study mode works through personalized system instructions. It is a provisional solution that allows us to observe how users interact and adjust the behavior of the model based on that feedback. The company plans to integrate these functions directly into the main models, once you have learned enough from this first stage. It is also exploring new capabilities, such as clearer visualizations for complex concepts, long -term learning objectives and a finer customization depending on the student’s level. At a time when the educational debate on these models is still open, the bet of the American startup comes with a clear message: it is not enough to have answers. You have to teach to understand them. China, for example, is already building that future with tools like Deepseekintegrated directly into university programs. With this step, the ball is on the roof of other technological giants. How will Microsoft, Google or the new Asian promises? The competition is no longer measured in capabilities. Also in real utility in the classroom. Images | Xataka with Gemini 2.5 Flash | Screen capture In Xataka | Anthropic has seen that their users do not stop using the 200 euros plan a month of their AI.

The “Death whistles” Aztecs were always a mystery. Until we discovered why they give us so many chills

by

The “Death whistles” Aztecs have surprising peculiarity: their intimidated appearance, but much more does its sound. Although the artisans manufactured them in the shape of a skull and figures that are today interpreted as references to Mictlantecuhtlithe Aztec King of the underworld, it is his loudness that has been intrigued by archaeologists for years. Not surprisingly if one takes into account that when we take one of these instruments to the lips and blow, something occurs similar to a human cry. It’s hard to listen to it without feeling uncomfortable. A group of researchers wanted to go further and investigate why we feel what we feel when we listen to the whistles of Aztec death. The answer can be key to understanding a piece that is still involved in mystery. Death whistles? Exact. His name imposes, but not as much as his appearance and sound. The “Death whistles” Aztecs are instruments made with clay between three and five centimeters and skull form, a peculiarity that experts interpret as a reference to Mictlantecuhtli, the lord of the underworld. They also include Figures of the Snake of Fire and Owls. Experts believe that the original pieces were manufactured Between 1250 and 1521. Wars or rituals? The first references about them date from End of the 19th centuryalthough probably the most famous specimen was found between 1987 and 1989 in the Ehécatl-Quetzacóatl templein Mexico City. There the archaeologists located the skeleton of a human sacrifice with a whistle, which has given wings to the different theories that try to explain what they were used for. There are those who think that the Aztecs used them in wars to scare their enemies and who believe that their use was basically ritual and symbolic. According to them, the sound would accompany the dead on their trip to Mictlánthe Aztec underworld. To that last theory contributes that death whistles have been found in places where ritual burials and human sacrifices were made. Another interesting clue is that the piece located next to the skeleton recovered in Ehecatl-Quetzcalcóatla circular sanctuary dedicated to the god of the wind, Ehecatl. Today several copies are preserved in facilities of the National Institute of Anthropology and History (INAH) or the Berlin Ethnological Museum. And how do they sound? Here are A few examples So you can check it. Depending on how they are used, whistles produce a siseo or a much deeper, intimidating sound, similar to a human cry. Recently a group of researchers from the University of Zurich (UZH) set out to go nevertheless and answer two big questions: why do they sound like they sound? And why listening to them produces such an overwhelming feeling? Their conclusions were reflected in An article Posted in November in Communications Psychologya magazine of the prestigious Nature Group. How have they done it? With a combination of techniques. The team obtained recordings from several whistles, including two recovered in Tlatelolcohe performed computerized tomographs To create 3D objects and resorted to replicas of whistles made of artisans with clay simulating the characteristics of the originals. Then they registered the sounds and reproduced them to a group of volunteers. To document their reactions well, scientists submitted them to a neuroimaging study. The objective: find out how their brains reacted. What did they find out? To start they discovered that the whistles have “A unique internal construction”with two opposite cameras that generate turbulence in the air and produce that kind of shout that, if archaeologists are right, accompanied the ritual victims in their descent to the underworld. “The whistles have a very unique construction, and we do not know any comparable instrument of other pre -Columbian cultures or other historical and contemporary contexts,” Explain Sacha Frühholz, the professor of cognitive and affective neuroscience who directed the study. The Aztecs are also known for making instruments that imitated the sound of the wind or the songs of the birds. What did they feel when listening to it? That is the most interesting part of the research. The volunteers described the sounds as “extremely chilling and terrifying”, According to verifies The UZH. “The brain regions belonging to the affective neuronal system responded strongly to the sound, which once again confirms its intimidating nature. The team also observed brain activity in regions that associate the sounds with symbolic meaning.” In summary, the volunteers called him “very negative” and “frightening.” “Given the aversive/terrifying and associative/symbolic sound nature, as well as the locations of the excavations known in places of ritual burial with human sacrifices, its use in ritual contexts seems very likely, especially in rites and sacrificial ceremonies related to the dead,” They conclude The experts, who recognize in any case a handicap of their experiment: the test was done with listeners of modern Europe who did not know that they were going to listen to the sounds produced by the old Aztec instrument. Did they find out anything else? Yes, something interesting. The volunteers perceived the sounds of whistle as hybrids, between the natural and the artificial. “They were classified at the psychoacoustic level as a hybrid mixture of voice sounds and screams, but also caused by technical mechanisms,” says research, which slides that this double quality could influence the reaction of the listeners: sound evoked shouts of a human nature, but also tones generated with artificial objects.
