is renovating its bullet train with 5G-enabled windows and noise-cancelling cabins

High-speed rail is going through a phase of maturity where the differential is no longer so much speed, but rather productivity and comfort. In short: it wants to become a fully fledged alternative to flying in the business segment. While Spain is consolidated as the second country in the world in high-speed network and leader in technological interoperability, Japan (which was a pioneer with the Shinkansen in 1964) wants to regain its hegemony with deep digitalization. JR Central, the rail operator of the Tokaido Shinkansen, has announced which will equip the next premium suites of its famous bullet trains with windows with integrated 5G antennas and active ambient noise cancellation without the need for headphones. The news. The improvements are not cosmetic, but a serious commitment to transform the premium car into a work or rest environment comparable to a private office. 5G antennas on the glass. The technology is provided by AGCa Japanese company that weaves conductive microfibers into the glass to form an antenna that is connected to the on-board Wi-Fi router. While conventional systems bounce the 5G signal inside the train before reaching the router, antennas integrated into the glass keep direct line of sight with outside base stations. That is, a more stable Wi-Fi with a stronger signal. Integrated ANC. The system is called Personalized Sound Zone (PSZ) and has been developed by NTT. Its operation is like that of headphones with active cancellation: it detects the waveform of the ambient sound and from there, projects its inversion to cancel it. The main difference is that you don’t need to cover your ear: it uses a combination of microphones, speakers and spatially optimized low-latency processing. Why is it important. JR Central’s bullet train reaches speeds of up to 285 km/h, meaning it passes mobile network base stations so quickly that it often needs to reconnect to another radio. This phenomenon is known as handover and degrades the quality of the connection: it is the Achilles heel of connectivity in high-speed trains around the world. Yes, those internet outages also happen on the AVE. Finding a solution in windows is technically elegant and scalable. From the point of view of the premium segment, the robust connectivity and acoustic isolation without headphones places it in direct competition with the business class flight on routes within the country. Of course, in the absence of the price. For now, JR Central has only confirmed which will be more expensive than tickets for first-class Shinkansen Green Car seats, which already cost 40% more than a standard unreserved ticket. An example: standard ticket from Tokyo station to Kyoto (2 hours and 15 minutes) costs 13,320 yen and 18,840 yen for the Green Car, that is, 71 and 100 euros respectively. Context. The Tokaido Shinkansen is the busiest high-speed line in the world. Private compartments disappeared from the line in 2003 with the withdrawal of the Series 100 double-decker trains, which included private cabins. This new initiative means the return to the format in style two decades later. Regarding glass antenna technology, the collaboration between AGC, NTT Docomo and Ericsson has been going on since 2018. In fact, in 2019 this conglomerate of companies reached the world’s first 5G communication using an integrated fused silica glass antenna to transmit and receive 28 GHz signals, with average download speeds of 1.3 Gbps and maximum download speeds of 3.8 Gbps in a range of 100 meters. What JR Central is now announcing is the first commercial application in high-speed trains. And in Spain? In connectivity, there is a technological and approach gap. The AVE has Wi-Fi since December 2016 thanks to a system of outdoor 4G-LTE antennas combined with satellite, routers, servers and access points. That is, like what JR Central has just overcome: capturing the signal from outside and redistributing it inside. AGC’s solution for the Shinkansen eliminates this weak point by maintaining direct line of sight with the base stations, something especially critical at high speed. Of course, while PlayRenfe is universal for all travelers, the Shinkansen Wi-Fi will be in the luxury suites. Yes, but. The deployment is very limited: in the initial phase only a couple of suites will be installed in six trains, so coverage is residual against the park of operational units total and JR Central has not made public a roadmap for the expansion of these technologies. On the other hand, NTT’s noise cancellation technology applied to a train poses its own structural challenges, ranging from noise variations at 285 km/h to pressure changes in tunnels. It will be necessary to check the real effectiveness of the system under these conditions. In Xataka | There was a day when Japan was the leading high-speed country.

TikTok has dodged the bullet of the US veto. Although it has not been free

TikTok has announced through a press release the creation of a new one joint venture with which it seeks to meet the demands of the United States Government. This operation will give rise to a new subsidiary majority controlled by a group of American investors close to the president of the country. The agreement. TikTok now operates in the United States under a new entity, TikTok USDS Joint Venture LLC. The joint venture allows Bytedance to retain 19.9% ​​of the new company, with the rest under the control of three companies: Oracle, Silver Lake Management and MGX. The constitution of the new subsidiary will allow TikTok to continue operating normally in the country, complying with the executive order signed by Trump on September 25, 2025. The data. The main objective of the Joint Venture is to meet Trump’s demands. That user data remained in the United States was one of the main ones. “The majority U.S.-owned joint venture will operate under defined safeguards that protect national security through comprehensive data protections, algorithm security, content moderation, and software safeguards for U.S. users.” The algorithm. The content recommendation algorithm will be updated in the United States, leaving it in the hands of the joint company. The Oracle cloud will be in charge of ensuring this, and it will be specifically designed to make recommendations based on data from American users. Although the United States has gained access to the algorithm, it is not done with your property. Bytedance licenses, but does not sell its most valuable asset. Qor what is important. The fight between TikTok and the United States was not a whim, it was a geopolitical war around one of the most important social networks for China. trump even banned the application in the United Statesafter considering it a “risk to national security” in 2024, throwing a dart at Bytedance with a Protecting Americans from Applications Controlled by Foreign Adversaries Act made to measure. Within hours of completely shutting down, the president extended the deadline for the vetoin order to reach an agreement. Trump made it clear that, if China wanted reduce its tariff burden, the price to pay was TikTok. During 2025, the future of the social network was up in the air. Neither winners nor losers. There are two sides to this new agreement between China and the United States. For Bytedance, TikTok is not important in the United States only because of its unique users (less than 10% of its global base): it is also important because the bulk of creators that feed their algorithm from the country. Although it loses participation in TikTok in the United States, it maintains a user base. Maintains algorithm. Resolves tension without giving up one of your most precious assets. On the United States side, although it has not been able to take over the app 100%, it achieves one of its main objectives: that user data stays in the country.

an invisible weapon that blinded his soldiers without firing a single bullet

The number of Venezuelan casualties after the United States incursion in Caracas and the subsequent capture of Nicolás Maduro varies with the passing of the days and the sources, but it seems clear that it amounts to at least double digits (we speak of up to 100). In any case, another piece of information has now been revealed that amplifies the mission. In reality, Washington’s key weapon did not fire a single bullet. The attack that was not heard. Yes, the American operation in Caracas was not defined by explosions or columns of smoke, but by the sudden silence of radars, radios and command centers, a demonstration of force in which more than 150 aircraft acted in a coordinated manner to enter, hit and leave with hardly any visible resistance. In fact and how explains the Wall Street Journalthe key was not to destroy the enemy, but to leave him blind and disoriented from the first minute, unable to understand what was happening or to react coherently while special forces captured Maduro in the heart of Venezuelan power. The invisible weapon. At the center of that blackout was the EA-18G Growler, an aircraft that does not attack people or physical positions, but rather the opponent’s nervous systemspecialized in locating, jamming and neutralizing radars and communications until turning an apparently solid defensive framework into a collection of mute sensors and useless screens. While stealth fighters and bombers performed deterrence and targeted attack functions, the Growler ensured that the Venezuelan defenses they will never get to see them clearly, demonstrating to what extent electronic warfare has ceased to be a complement and has become the precondition of any modern high-intensity operation. Blind before hitting. The logic applied in Caracas reflects a lesson learned and refined in Ukraine– It is not necessary to physically destroy all enemy systems if you can overwhelm, confuse or fool them until void your operating profit. The Growler can simulate multiple targets on the radar, flood the electromagnetic spectrum with noise, interfere with command links and, if necessary, guide anti-radiation missiles against active emitters, creating temporary windows of absolute superiority that allow helicopters and ground forces to operate with minimal risk even in theoretically defended environments. The Russian defenses that did not fire. They recalled in Insider that the most striking result was that none of the Russian-made air defenses in Venezuela’s possession managed to shoot down a single plane American during the operation, despite the fact that the country had on paper respectable systems such as S-300VM, Buk-M2, Pantsir-S1 and radars of Russian and Chinese origin. The image of airspace simply collapsing under a well-planned operation It has been devastating from a symbolic point of view, because it shows that having advanced systems does not guarantee their effectiveness if they are overcome by a combination of surprise, electronic warfare, stealth and multi-domain coordination. 9A83ME launcher of the S-300VM Antey-2500 missile system Not everything is the system. The Venezuelan failure cannot be explained solely by the technical limitations of the Russian systems, but also due to structural factors such as the state of maintenance, the real integration of the defense network, the quality of command and control and, above all, the training and experience of the operators. An anti-aircraft system is only as effective as the doctrine that supports it and the people who operate it, and in Caracas it became clear that, in the face of a well-trained Western force, even feared equipment can be defeated. reduced to passive spectators if they do not function as part of a coherent whole. Repeating pattern. What happened in Venezuela is not an isolated case, but rather fits with a pattern observed in other scenarios like syria or attacks Israelis against Iranwhere air defenses of Russian origin have shown irregular performance against forces that master electronic warfare and stealth. Although in Ukraine, operated directly by Russia, these defenses have worked betterhave also not achieved the invulnerability that their reputation promised, which reinforces the idea that their effectiveness decreases considerably when faced with adversaries capable of combining interference, cyberattacks, deception and precision attacks. Without triumphalism. There is no doubt, for the United States, about the Caracas operation strengthens confidence in its ability to penetrate airspace defended by Russian systems, but it also emphasizes that this success depends on exhaustive planning and intensive use of invisible capabilities that are not improvised. The lesson is not so much that Russian defenses are useless, but that in the face of an adversary that dominates the electromagnetic spectrumEven feared systems can be neutralized long enough for a decisive operation to take place. The war that is not seen. If you also want, the assault on Caracas leaves an uncomfortable and increasingly obvious conclusion: modern war is decided before the first shotin an intangible space made of signals, links and frequencies, where whoever controls the information controls the result. He Growler He did not fire a single bullet, but its effect It was more devastating than that of many bombs, remembering that in current conflicts lose seeing and hearing is almost always equivalent to losing the war before it begins.

OpenAI has turned the global economy into Russian roulette with a single bullet: AGI

2025 is being the year in which OpenAI has ceased to be a technology company and has become a black hole that attracts capital, expectations and the destiny of companies that move billions, with a ‘b’. Sam Altman has designed a scenario where there are only two possible outcomes: AGI for them or collapse for everyone. Why it is important. OpenAI’s valuation has reached $500 billion as an unlisted company. It has moved more than a billion (also with ‘b’ and it is not a false friend of “billions”) in deals in recent weeks. Those figures only make sense if they get the AGI (Artificial General Intelligence). If not, everything explodes. The panoramic. A year ago, a round of 6.6 billion It seemed like an astronomical figure. Nine months later, 40 billion. Now we talk about 100 billion with NVIDIA. And so naughty. When we reach these magnitudes (and they are repeated) we stop talking about simple capital injections and talk about binary bets on the future of the world economy. The problem is that these figures have dragged other giants to the same precipice. The backdrop. Microsoft was the first to get hooked. Then he considered divorce and since then They are still together, but sleeping in separate beds. Furthermore, OpenAI has achieved something more dangerous: chaining Oracle, AMD and above all NVIDIA, the most valuable company on the planet on the stock market. If OpenAI clears its throat, all NVIDIA knobs jangle. And if NVIDIA falls, it drags down the S&P 500. The domino effect would reach pension funds, corporate spending and the US GDP. And from there, a chain effect for the economy of the rest of the world. behind the scenes. NVIDIA is not only funding OpenAI, it is also guaranteeing some of the debt the startup needs to build its own data centers. Is circular money: NVIDIA sends money in exchange for shares. OpenAI uses it to rent chips from NVIDIA. And those contracts allow NVIDIA to take on more debt to continue financing OpenAI. A loop that only works as long as the music continues playing. When the Titanic began to sink, the orchestra’s musicians were forced to continue playing. Yes, but. AI already works. It is already transforming sectors. Nobody doubts it. You don’t need to be AGI to have value. The problem is that OpenAI does need AGI to justify these insane valuations. They have set up a structure where any slowdown, any sign of doubt, will trigger panic. The money trail. Altman has found in Masayoshi Son to the perfect partner. The SoftBank founder has a history of big bets blowing up and miraculous saves (Alibaba, ARM). The Altman-Masa combination is a capital cannon pointing skyward. But it is also a detonator: if they fail, the explosion will be proportional to the ambition. According to Altman’s analysis, OpenAI has to beat Google before the latter’s TPUs hit the market and change the rules of the game. That’s why the rush. That’s why Atlas. That’s why the agreements with Broadcomconversations with Intel, promises to AMD. It’s not just about building the best AI, it’s about surviving until you get it. The big question. What if another macroeconomic event stops everything before superintelligence arrives? OpenAI is racing against the clock, it needs AGI before the economy trips over its own shadow. Meanwhile, the market rewards these alliances with instant increases. Oracle has multiplied its value just by announcing agreements with OpenAI. Capitalism of expectations: benefits are no longer needed, only promises of a future that does not yet exist. The same thing happens to others because OpenAI is the new King Midas. Decisive moment. This is no longer a bubble that can burst. It is a bet that can fail. And the difference matters. A bet drags down everything around it. OpenAI is already too big to fail without causing a cataclysm. Which makes it probable an Intel-type state bailout if things go wrong. Altman knows that many AI companies will disappear when the euphoria ends. Only the largest will survive. OpenAI plays at being so big that it has to be rescued. It’s already happened with the dotcoms‘. It can happen again. OpenAI has forced a binary scenario: either we achieve AGI or we face a brutal recession. AI works, transforms, improves processes. But that is no longer enough. We need trillions in value created. And if they don’t arrive in time, the collapse will be rapid. And ugly.

It is a direct bullet to the blue links that restless and excites equal parts

This year’s google has left us with very interesting pearlsespecially as far as artificial intelligence is concerned. It is clear that Gemini It has been the most important tourist attraction of this year and makes all the meaning of the world. It has been so that the company has completely set aside Android In your most important event. Although of course, for this we already had A separate event With all the news. In addition to all the tests with Project Moohan and the Google glasses with GeminiI have also had the opportunity to try Ai modethe new and revolutionary function with which Google intends to completely transform your search engine. We are no longer facing simple results with some of the above; This is a radical change in the way of looking for information, and it was all that we expected from Google from the AI ​​boom. Finally, the company has decided to take the step and under these lines I tell you what it seemed so far. Google Search makes the leap and transforms completely into a search engine with AI To access AI Mode I had to change my region to the United States through Search Labs, since it is not yet available in Europe. Once the change is made, on the main page of Google, where the “I will be lucky” (may rest), now “ai mode” is now. It will also arrive for mobiles, but I still couldn’t try this aspect. Here instead of typing keywords and get a list of links, now You convers with the search engine as if you’s talking to a person. Image: Xataka During my first searches I tried to determine if Gemini would guess the name of a place I went without me saying anything, but describing what was in the menu. “I don’t remember the name of a restaurant I went in Jaén, but I know there were tacos in the letter. Could you tell me what it was?” I asked him in English (the only language available for now). What I got was not a simple list of establishments, but a complete, contextualized response and with all the relevant information On several restaurants that fit my request. I also tried “I am looking for an economic gym for Madrid that does not exceed 35 euros.” The answer was instantaneous and, most importantly, exactly what I needed: concrete options with details about prices, schedules and valuations, all perfectly organized. Main tab of AI Mode in Search | Image: Xataka Here, logically there is still room for hallucination, so we must be attentive and make a double check. However, for practically all my searches, I found what I was looking for an instantaneous waydetailed and precise. Ai mode is not simply gemini integrated into the search engine. As explained to me on Google, the system uses a technique called “Query Fan-Out”, which Divide your consultation into multiple sub -themes and performs hundreds of simultaneous searches. It is as if you had a researcher working for you at full speed. Image: Xataka This approach allows the search engine deepen the web much more than a traditional searchdiscovering hyperrelevant content for your specific question. The function uses a personalized version of Gemini 2.5which is now integrated into both AI Mode and AI Overviews in the United States. Not only seeks: it also goes to action Image: Xataka The most impressive thing about AI Mode is that it is not limited to informing you, but that It can help you complete tasks from beginning to end. The example of the entries of the reds explained by Google In his blog It is good, because the search engine guides you step by step from options to buy them, including the possibility of filling forms and making payment through Google Pay. This function will be initially available for events, reservations in local restaurants and appointments, with the collaboration of platforms such as ticketmaster, Stubhub or Resy. The control, yes, is still in the user’s hands at all times. Although of course, we still have no details about his arrival in Spain. Search Live: Google Lens’s definitive evolution I also had the opportunity to try Search Live, one of the most surprising novelties. This function allows to interact in real time with the search engine Using the mobile camera, turning Google into a true visual partner. I described it as having a “todologist” at any time to help us in any task. During the demo, I simply pointed to the camera to a shelf full of board games and books, and I could ask directly about what I was seeing. The system identified the objects and offered me detailed information about each one, answering my questions in real time as if I had an expert by my side. Search Live is what Google Lens should have been for years. With the integration of AI, it now makes much more sense and its use is tremendously intuitive. It’s like having a personal assistant who sees what you see And you solve any questions instantly. Deep Search: a group of scientists at your disposal Another promising function that will soon arrive at AI Mode is Deep Search. Is designed for when you need an exhaustive investigation on a topic. It really is something similar to the models of the “deep research”, with the ability to reflect, but available in Search, which combines the search concept in a product with more packaging. As they could explain, Deep Search carries Query Fan-Out technique to the next level, doing hundreds of searches, crossing information from different sources and preparing a full report with references in minutes. It’s like having a team of researchers working for you. The searches will change from here to very little, and there is nothing to stop this train Ai Mode is all we expected from Google when he took a certain traction with the generative AI, something that, so we have seen in the Google … Read more

Intel has a bullet in the bedroom. A bullet capable of helping you compete from you with TSMC

The possibility of Intel ending chopped and its semiconductor factories become part of TSMC production infrastructure It is on the table. As we explained two days ago, this producer of Taiwanese integrated circuits and the American chip designer Broadcom are interested in getting two fundamental parts of Intel. TSMC is preparing an offer that would allow you to control Intel integrated circuit manufacturing plants with the purpose of developing your manufacturing infrastructure Beyond Taiwan’s borders. On the other hand, Broadcom is also preparing an offer to get the integrated circuit design and marketing divisions of Intel. In any case, if the TSMC initiative will finally prosper will stumble The opposition of the government led by Donald Trump. Currently it is unlikely that the administration approves the purchase of such an important division of an American company by a foreign company. Discordant voices are being raised within Intel Ben Sell, Vice President of Intel Technology Development, confirmed At the end of last September that the 18A node already has the maturity necessary to enter large -scale production in 2025. and also assured that it will benefit from the resources that have been reallocated since the 20A node. In the current scenario the 18A node will be the true protagonist. In fact, and this is really important, Intel has confirmed which will receive a maximum of 3,000 million dollars within the framework of the ‘Chips and Science Act’ program to manufacture semiconductors for the US government in a reliable way. The 18A node is the best opportunity that Intel has to resume the course and improve its competitiveness The name of this plan, “Safe Enclave”, reflects one of the requirements required by the Administration: Chips must occur in the strictest confidentiality. And, as we can intuit, these integrated circuits will be manufactured in the 18A node. Definitely this integration technology is the best opportunity that Intel has for resume course and improve your competitiveness. In fact, voices are being raised within the company itself that demand a little patience to give this node the opportunity to place Intel on the path of recovery. This statement by Joseph Bonetti, main manager of Intel engineering programs, expresses this vision very well: “Intel leaders, Board of Directors of Intel and Donald Trump’s administration, please do not sell or give the control of Intel Foundry to TSMC just when Intel is taking the technological front and starting to take off. It would be a terrible and demoralizing error” . Bonetti also maintains that Intel is not lagging for its competitors, and that the advances that their engineers are achieving in the field of chips production are very important. At the current situation there is no doubt that the 18A integration technology is the best Intel asset to recover health, but it is important that we do not overlook that its technicians have been calibrating more than a year and adjusting their first lithography equipment of extreme ultraviolet (UVE) and haute opening manufactured by ASML. Intel has them in its Hillsboro plant (USA). The first tests with this machine presumably carried out them at the end of 2024, and in 2025 the preliminary tests that pursue to manufacture circuits integrated in the 14A node will begin. It sounds exciting. We will follow the track to this machine very closely to keep you aware of all progress.
