If we think about the ancient egyptian technologythe images that come to mind are the monumental ones pyramids of giza or the great obelisks of the New Kingdom. However, the foundations of this technological feat were forged long before, as pointed out by a new archaeological study that has identified the oldest rotating metal drill in Egypt, a discovery that advances the mastery of this tool by more than two millennia and that rewrites the history of the technology in the Nile Valley. Where was it found? The story of this discovery, the truth is, could fit into a series called “Archaeological CSI”, since it all started with an identified object like a tiny piece of metal that measures just 63 millimeters and weighs 1.5 grams. This was excavated a century ago in tomb 3932 of the Badari cemetery in Upper Egypt, and had lain forgotten ever since. Literally ignored in a drawer at the Museum of Archeology and Anthropology at the University of Cambridge, was this object that caught the attention of a research team that decided to follow his trail using the most modern technology. A drill. What was initially classified as a simple and insignificant punch was actually a bow drill. This is the conclusion of this new exhaustive analysis of the piece, where they have been able to see unmistakable marks of its mechanical use such as rotational grooves, a specific curvature for tension and microscopic remains of leather rope. How it worked. What today is a drill that works connected to electricity, in ancient times, the bow drill worked by winding the string of a bow around an axle that held the drill bit. In this way, by moving the bow back and forth, the drill bit rotated at high speed. Its importance. As the researcher points out, the Egyptians had the ability to master this rotation technology more than two millennia before the first sets of drills that humanity knew today. This once again shows us how advanced it could be in its context in the art of construction. Unusual alloy. The big question here is how such an ancient tool could drill hard materials without deforming. And the answer is in chemistry. In this case, the researchers they used portable X-ray fluorescence spectrometry and saw that the drill was not made of just copper, but was an alloy of arsenic, nickel, lead and silver. A combination that is not coincidental, since the presence of arsenic gave the copper a much higher hardness, transforming the metal into a high-performance tool capable of resisting continuous friction. The trade. Beyond the mechanical value, for historians this mixture of metals is also really important because it points to strong commercial connections with the eastern Mediterranean, revealing that predynastic Egypt was not only innovating technologically, but was connected to a global network of exchange of exotic materials long before the unification of the pharaohs. The technological history. Until now, the official narrative placed the perfection of these rotating metal tools much later in the Egyptian timeline. But now, this tiny forgotten object forces us to recalibrate our understanding of human ingenuity.

While the world fights for the most advanced chips, there is a company making gold with the ones that go inside your washing machine

by

If you have walked through an industrial estate, you have surely come across the typical warehouse with the sign “Spare Parts and Bearings (Insert name)”. And it’s easy for you, at that moment, to wonder what the hell a bearing is and how the rest of the businesses are closing, except for ‘Rodamientos Paco’. Well, in the world of technology there is also a ‘Paco Bearings’. Is called Texas Instruments and, in full era of sophisticated chips, artificial intelligence and quantum computingis breaking it with something very specific. Boring chips. In short. Companies are in the middle of the results presentation period. In this round, the managers inform their shareholders about the direction of the company, while allowing us to learn about data on upcoming devices or business plans. Texas Instruments usually goes unnoticed in these more ‘techie’ times, but they are finishing up a fiscal year with very positive numbers. The fourth quarter they closed with 4,420 million and anticipate increasing to 4,680 million in the first quarter. In the last three months, its share value has increased by 18%. Its shares are among the highest among companies in the same sector and, as we said before, the curious thing is that it is doing all this almost silently. Live outside the hype. You can constantly read information about cutting-edge chips on Xataka. It is true that the current nature of components is marked by the current RAM memory crisis either of SSDsbut the snapdragonthe Apple Silicon, the latest from NVIDIA or AMD It is what usually marks the conversation. They are the most sophisticated and interesting chips, but a coffee maker does not need a chip like that. That’s where Texas Instruments comes into play. Because calling their chips “boring” is not an exaggeration. They are outside the AI ​​hype, the data centers and the most exciting features because its market is different: sensors, connectivity, controllers. Where are Texas Instruments chips? In routers, smart refrigerators, washing machines, air conditioners, as secondary chips in televisions, in remote controls, in calculators or in smart smoke detectors. But they not only make chips, but also another series of integrated circuits for wireless communications, signal processing in all types of devices and even sensors that detect tire pressure, engine temperatures or the air conditioning system. Texas Instruments chips and sensors are in… everything. Even in weapons. An example of a tiny sophisticated chip in the headphone stick… with only 16 KB of RAM. Because you don’t need more Huge investment. And the company is not sitting idly by with the huge amount of money it is making with its ubiquity strategy. a few days ago, Bloomberg reported on the agreement that Texas Instruments had reached to buy Silicon Labs. Also American, also with ‘boring’ chips that They are inside ‘things’ of all kinds. The operation is not closed, but the smell of it caused Silicon Labs shares to increase 51% to more than $206. The curious thing? That Texas Instruments is willing to pay more: up to $231 per share to investors. The operation has not been closed, but there is talk of a purchase of 7.5 billion dollars, well above the 4.5 billion that Silicon Labs is “worth.” Great year ≠ perfect year. All of this is… outrageous, but it indicates something very specific: they are spending a lot of money to reinforce a huge, stable market that goes unnoticed in a time when everything revolves around artificial intelligence and sophisticated technology. The purchase of Silicon Labs, paying such a high premium per share, shows that they know very well what they are getting into and the value of a market in which they are a key player. But one thing must also be noted: although revenues rose, annual profits did not increase at the same rate. He total invoiced increased by 13%, but as they have also invested more, this increase in costs reduced the profit margin, which “barely” increased by 4.2%, with some quarters being worse than others (in Q4 they fell by 3.5%). They haven’t had a perfect fiscal year, but there is one thing that is undeniable: they are still the kings of their niche. If we can describe being everywhere as a “niche”.

The most advanced Spanish military satellite suffered an impact in space more than a week ago. There are still no clear explanations

by

For years, Spain has invested millions of euros in building a space communications system designed for extreme scenarios, from military operations to international emergencies. One of its pillars, the satellite SpainSat NG II, It took off in October with everything as planned and within a program presented as the most ambitious in Spanish space history. However, something happened very soon during its transfer to its orbital position. More than a week after an incident was acknowledged, what surrounds the satellite’s true status is a combination of minimal data and silence that leaves many questions open. An aging statement. The only thing confirmed so far comes from a statement released by Indra January 2, 2026in which it is recognized that the satellite suffered the “impact of a space particle” during its transfer to the final orbit. The incident occurred about 50,000 kilometers from Earth, still an intermediate phase of the journey to its geostationary position. Since then, the technical team is analyzing the available data to determine the extent of the damage, but no assessment of its operational status or the actual consequences of the impact has been made public. The launch of SpainSat NG II took place on the night of October 23 in the United States, already in the early hours of the 24th in Spain, aboard a Falcon 9 bound for a geostationary transfer orbit. From there, the satellite had to complete a journey of several months until reaching its final position about 36,000 kilometers from Earth, a process that, according to the CEO of Hisdesat told Euronews, usually takes between five and six months. The impact recognized by Indra occurred in that intermediate phase of the journey, when the satellite had not yet reached its final operational orbit. The reaction. In that same statement, Indra explained that Hisdesat, operator and owner of the satellite, had activated a contingency plan to guarantee that the committed services are not affected. The formulation fits with the logic of a two-satellite system, which seeks to ensure continuity of service even in the event of unforeseen incidents. However, the specific measures adopted and the current degree of dependence on the affected satellite within the program as a whole have not been detailed, which limits the ability to evaluate the real scope of this response. Twin units. SpainSat NG II is not an isolated satellite, but one of the two central pieces of a system conceived as a long-term strategic infrastructure. Along with his twin, the SpainSat NG Iis part of a program promoted by the Ministry of Defense with an investment of more than 2,000 million eurosintended to provide Spain with its own secure communications. The first satellite has already been operational since the summer, while the second was to complete the system, a context that explains the attention that any anomaly in its deployment has generated. The secrets of the satellite. From a technical point of view, SpainSat NG II represents a notable leap over previous generations of government communications satellites. Built by Airbus on the Eurostar Neo platformthe satellite has dimensions close to seven meters and a mass of around six tons. Its payload incorporates an X-band active antenna system that, according to Airbus, offers the equivalent functionality of 16 traditional antennas and allows coverage to be dynamically adapted up to 1,000 times per second, a capacity designed for changing and demanding operating scenarios. More questions than answers. With the information available, the range of scenarios remains wide. An impact from a space particle can result in minor damage without operational consequences, but also in a more serious impact that forces the functions to be limited or the deployment of the satellite to be reconsidered. Indra has even left open the option of a replacement if necessary, and maintains that, in that case, the satellite would be replaced as soon as possible. The absence of specific technical data makes it impossible to know whether this is a controlled incident or a problem with deeper implications. Given the lack of public updates, from Xataka we have contacted Indra to find out if there was any news about the status of the satellite. The company’s press office has responded to us that, for now, they have no details to share about what happened. That silence prolongs the uncertainty around a strategic system that has not yet entered service and leaves open key questions about the real scope of the impact.

put UBTECH’s most advanced humanoid robots to work

by

In Fangchenggang, where control windows and cargo trucks outline the routine of a border with Vietnam, an experiment is being prepared that will not take place among laboratory prototypes, but among travelers, agents and logistics workers. China has chosen this place to test humanoids in real situations, with deliveries scheduled from December and very specific functions: guiding movements of people, supporting logistical tasks, participating in certain commercial services and carrying out inspections both at border posts and at industrial facilities. An ambitious contract. The agreement signed between UBTech and a center specialized in robotics in this border city amounts to 264 million yuan, about 34 million euros, and establishes the deployment of the model Walker S2 in different types of scenarios: border crossing, logistics zones and industrial complexes. According to the company, the humanoids will be intended to guide flows of people, organize internal transportation operations and carry out structured inspections in facilities linked to steel, copper and aluminum. From prototypes to 800 million. UBTech arrived at Fangchenggang with a model that is no longer presented as a prototype, but as an industrial product. The Walker Series accumulate valued orders by 800 million yuan by 2025, not including educational and research models. UBTech assures that it has already begun to deliver the first industrial batches of the Walker S2 and that its objective is to accelerate production at scale, with a view to manufacturing thousands of units and reducing costs so that humanoids enter real environments. Robotic administrations. The rollout of UBTech fits into a broader trend within the Chinese public sector. The Zhejiang immigration office already uses robots for daily tasks, such as support in people flows and information services. At Hangzhou airport, one of these systems answers simple questions to passengers, while at the top of the Shanghai Cooperation Organization, held in Tianjin, a multilingual robot developed by iBen Intelligence was used for protocol assistance. The Fangchenggang initiative is part of a coordinated strategy from the State to organize the humanoid sector in China. The Ministry of Industry and Information Technology created a national committee specific for this type of robots, chaired by the organization itself and made up of companies, innovation centers and relevant technical figures. It includes executives from UBTech, Unitree, AgiBot and representatives of the Shanghai innovation center. The goal is to set standards and accelerate the transition from laboratory to commercial and administrative applications. What is relevant is not only that the humanoids have contracts and assigned functions, but also the place where they are going to test them. A border is a regulated space, with people in transit, goods, controls and tight times. If they work there, it will be easier to propose new applications in other public contexts. The Fangchenggang Pass serves as a laboratory, but also as a stage to observe what sharing tasks between machines and human workers entails.

The microprocessor that advanced the Intel 4004 was not in a computer, but in a secret place: an F-14

by

We are used to thinking that the history of microprocessors begins with the Intel 4004. Even those who are not experts have it associated with it as the first big chip that inaugurated the era of personal computing. But that is not the only possible story. There was another design, less known and outside the commercial circuits, that began operating before the 4004 reached the market. It did not appear on a computer or calculatorbut in a F-14 Tomcatand for almost thirty years it was invisible to the public. What that plane had inside was a processor designed to do something that no commercial chip did at that time: automatically calculate speed, altitude or wing position while the pilot maneuvered. That system, known as MP944, had been in service since 1970, when the 4004 had not yet been introduced. Its context was completely different from that of Intel, because it was not designed for the market or to be licensed, but rather to fulfill a requirement of the military program marked by the tensions of the Cold War. A secret microprocessor in the bowels of an F-14 The novelty was not only that it made calculations, but that it did so automatically and digitally, something unusual in on-board systems from the late sixties. The MP944 processed sensor readingsapplied aerodynamic equations and provided data that influenced the behavior of the plane, reducing the pilot’s workload. It was not a passive assistant, but a module capable of interpreting those readings and providing results fast enough to be integrated into actual flight control. That is why it was considered a technology ahead of its time. The declassified documents in the nineties show that the MP944 combined advanced MOS technology with a 20-bit parallel architecture capable of executing pipeline calculations, something unusual for its time. Its frequency was 375 kHz and it could process specific mathematical operations efficiently enough to be integrated into real flight systems. According to the figures collected in Holt’s work and in the subsequent review by Tom’s Hardware, this performance placed the MP944 clearly ahead of the 4004 in number of instructions executed, although it was never intended as a general-purpose commercial chip. They were two different approaches: one for a military aircraft, the other for a commercial device. When Holt’s work came to light decades later, He argued that the MP944 should be considered the first microprocessoreven though it was not on a single chip nor had it been marketed. Intel engineers, such as Ted Hoff and Federico Faggin, disagreed and argued that 4004 was the first in integrating all the essential functions of a CPU in a single piece of silicon and with general use. Russell Fish, a former Motorola engineer, reviewed the MP944 documentation and described it as an advanced microprocessor for its time, while Richard Belgard saw it as an overly specific system, designed only to keep an airplane in flight. Holt maintained that the reason no one knew about MP944 for years was because his work had been classified and subject to military restrictions. He said he spent decades requesting the release of the documents and was only able to do so when, in 1997, he won the support of Congresswoman Zoe Lofgren for the Navy to authorize their publication. With the documentation now available, the Navy qualified that version and maintained that Holt’s work had not actually been classified, but that what was missing was the company’s authorization to release the records. Garrett AiResearch admitted that they were no longer clear about what had happened, because the people who managed the case had left the company. When the information became available, Russell Fish claimed that MP944 was so advanced for its time that, had it been known, could have accelerated the development of the sector by up to five years. The creators of the 4004, such as Federico Faggin and Stan Mazor, openly disagreed and pointed out that the merit of the commercial microprocessor was to integrate all the essential elements on a single chip and make it viable for multiple applications. Richard Belgard qualified this position: he recognized the technical value of the MP944, but saw it as a system designed for a single purpose, without the capacity to open its own market. The debate about which was the first microprocessor is not resolved with a date, but with a definition. The 4004 was the first to hit the market as a commercial, integrated and programmable chip, and that merit explains its place in manuals. The MP944, on the other hand, previously demonstrated that it was possible to process data digitally and feed control systems in real time, even if it was done while locked in an airplane and outside of public space. One opened an industry; the other anticipated capabilities. Both represented different ways of understanding what a microprocessor could be.

send an army in front of Russia with its most advanced tanks

by

Since 1945, Germany has lived cautiously everything related to the use of force beyond its borders. Even when he participated in international missions in the Balkans, Afghanistan or Mali, he always did so in a rotating, temporary format and under strict frameworks, avoiding establishing a permanent presence. The memory of the Second World Warthe initial demilitarization and the subsequent political reconstruction left a doctrine where stable deployment abroad was, more than a red line, a taboo. And then came the Russian invasion of Ukraine. The German deployment. Germany’s decision to establish its first brigade permanently deployed abroad since 1945 marks a historic turn in its defense policy and European military architecture. The creation of the 45th Armored Brigade in Lithuania, with 4,800 soldiers and civilian support personnel, responds to an increasingly clear reading of the Russian threat and the recognition that the defense of NATO’s eastern flank is, in reality, the defense of Alemani herselfto. The Chancellery in Berlin not only assumes this presence as a symbolic gesture, but as a structural pillar of a new military era, in which Europe must assume greater responsibilities strategic, reduce absolute dependence on the American umbrella and rebuild capabilities what were deliberately dismantled after the end of the Cold War. The brigade is, therefore, both a message to Moscow as an internal message: Germany is abandoning its former military prudence to occupy the role that its economic weight demands, and that its partners (and adversaries) take for granted. Kamikazes, software and more. He German rearmament It is not limited to heavy armor or territorial presence: it extends to the domain of war through saturation and accelerated adaptation, where kamikaze drones have become one of the most decisive tools of contemporary combats. The plan for acquire 12,000 drones suicide bombers, with contracts of around 300 million euros for each manufacturer, reveals a clear doctrinal change: the armed forces should no longer accumulate equipment in static arsenals, but rather maintain them in permanent update cycles, with the bulk of the arsenal under the custody of the industry itself to be modified almost in real time. The war in the background. The reference is direct: in Ukraine, innovation cycles are measured in weeksnot years. Every change in software or payload redefines the tactical value of the dronewhile traditional systems become obsolete due to the frenetic pace of electronic countermeasures. This massive purchase points to a military on the edge facing Russia that understands that the battlefield of the immediate future will be hybrid, digitalized and deeply dependent on agility to adapt to an enemy that learns as quickly as it attacks. Leopard 2A8. The deployment of the 45th Armored Brigade cannot be conceived without it Leopard 2A8the most advanced version of the German battle tank, updated based on the lessons learned from the systematic destruction of armored vehicles in Ukraine. Far from abandoning tanks, Germany has concluded that They are still essential for combined operations, but only if they adapt to an environment where the priority threat is no longer anti-tank missiles guided from hills, but cheap drones capable of descending on vulnerable domes. A tank to anticipate. Hence the integration of Trophy system active protection, early warning sensors, modular armor and electronic packages prepared to counter swarms or loitering munitions. The brigade is thus deployed not as a symbol of the European industrial past, but as a platform that attempts anticipate war to come: coordinated mobility, continuous real-time intelligence support, layered anti-drone defense, and a distributed weapons network that prevents excessive concentration of risk. The presence of the Leopard 2A8 is less a reaffirmation of the tank as an icon and more a doctrinal statement: the ground battle is still valid, but only if it is handled with precision, integration and constant adaptation. Rearm to last. On the whole, these movements They express a conclusion that is already beginning to be accepted unambiguously among European capitals: the peace of the last thirty years was a historical exception, not the norm. The Russian invasion of Ukraine has forced Europe to rebuild military industryreactivate strategic reserves, reinforce borders and recover the idea of an integrated defensesustained and modernized. Germany, which for decades was considered the “weak link” in European defense, is reconfiguring itself as the core potential continental rearmament operation. The 45th Armored Brigade in Lithuania, the 12,000 kamikaze drones and the Leopard 2A8 are not isolated pieces, but pieces of a same transition: preparation for a scenario where deterrence no longer depends solely on political will, but on technological capacity, speed of adaptation and territorial firmness. If you also want, the sign to Moscow is direct: the baltic border It is not a negotiable void, but a very clear line on which the greatest economic power in Europe now stands, permanently. And this time, with armored vehicles, drones, reactivated industry and a strategic mandate that looks decades forward.

The Hypershell X Pro is presented as the most advanced exoskeleton. We have tried it for a week and there is an obvious dilemma

by

He Hypershell X Pro It is one of the most curious products of the moment. The question is simple and at the same time uncomfortable: are we facing an exoskeleton that really helps you walk more and train more, or are we facing a shortcut that stops making sense if you are already in shape? In a new 24/7 of the Xataka YouTube channel We’ve taken it to a week of continuous use to understand the extent to which that extra push really changes the experience. For a full week, Dani Mangas, who already played with Amazon’s best-selling TVlived with the Hypershell X Pro inside and outside the home. She tested its different support and resistance modes, configured the app with her physical data, and adjusted the support to find the sweet spot. “I literally felt like I was in a science fiction movie.” From that first sensation began a video analysis that combines ergonomics, autonomy and real performance. Hypershell X Pro: wearable technology to move with less effort (or train harder) The assembly is surprising because of how simple it is. The Hypershell The app guides the initial process by asking for height and weight to adjust the anchor point at the hips. “Although it seems crude at first“, explains our colleague, it attaches easily to the body and transmits a firm sensation from the first moment. The start is almost immediate: just turn it on to notice how it starts to push. Dani first tried Eco mode, a gentle help that he describes as “as if someone grabbed you by the waist and pushed you forward a little.” From the app itself or with the buttons on the device you can change mode and intensity without depending on the mobile phone. The funny thing is that it doesn’t feel invasive: it helps, but it makes it clear that the one walking is still you. Away from home is where the Hypershell X Pro shows its character. On the flat the ride becomes more fluid and lighter, but it is when climbing where the difference becomes evident. With Hyper mode activated, the leg “literally raises itself”says Dani. On each slope the push reduces the load on the legs and the feeling of fatigue. The system reacts well, although when stopping there is a slight delay before moving again. Is it more noticeable on long slopes or during frequent starts and stops? Stairs are another area where the Hypershell X Pro comes into its own. In the uphill sections, the assistance raises the leg almost effortlessly, “as if someone was helping you from behind,” says Dani. On the other hand, when going down, a light brake still in beta phase acts, useful but far from being its strong point. Fitness mode goes full circle: adding resistance to every stride, just like walking with weight. Is it worth training with resistance versus “assisted” walking? “The value of the Hypershell X Pro is inversely proportional to your physical fitness,” Dani says in the video. The truth is that, after a week of use, There are moments when it surprises more than expected. and others in which it leaves doubts about who it is really aimed at. The interesting thing is to see how it behaves in each scenario and how far that promise of assistance or resistance goes. All that, and the final verdict, It’s on Xataka’s YouTube channel.

Madrid Metro has spent millions on advanced machines to cover them like shacks

by

It was February 14, 2024 when the Community of Madrid confirmed the last investment with which he was going to get married had been committed: 145 ticket vending machines to access the Madrid underground. The deployment came in large numbers. The almost one hundred and a half devices are part of the second phase of the Metro Technological Improvement Planan investment that also includes, for example, the renovation of hundreds of Metro access turnstiles. The investment tries to give a new face to facilities that are beginning to become small after not having received large investments in the last 20 years. Now, line 6 is being modernized, line 11 is being expanded and the stations are receiving new equipment to adapt to the new transport titles. Click on the image to go to the original tweet Equipment that, in the case of these machines, will be deployed in 19 stations. The first ones, boasted the account of X of the Madrid Metrothey arrived this same week. The leap in quality is evident: 42-inch high-definition screens and even the possibility of opening a video call with Metro services to ask for help if any complications arise. Latest technology devices to be distributed at some of the busiest Metro stations in the capital such as those at the airport, Nuevos Ministerios, Feria de Madrid or Príncipe Pío, among others. Very advanced machines with “Metta’s 4.0 technology,”in the words of the company itself. Machines to which Metro de Madrid has had to put a plastic umbrella. And of course, they have unleashed mockery on social networks. 7.7 million euros and a piece of plastic “It’s plastic. Greetings” This has been the answer that the Madrid Metro has given X to a multitude of users who have asked why the company has put uralite umbrellas on its newest and most advanced machines. Despite describing the innovations and advantages of these machines, many users have focused on that plastic appendage that appears at the top of the machine. An appendix that, without a doubt, is reminiscent of the uralite roofs, everything must be said. Indeed, we could continue with the concise answers of how the person behind the social networks of the Madrid Metro has tried to appease the responses to the shabby difficult to explain solution that the company has used to protect its machines. Madrid Metro has defended itself reiterating that this plastic roof has been installed because the station is leaking. Some leaks that, according to the company, are not its responsibility and, therefore, for the moment the machines will be protected with this particular umbrella for as long as necessary. Meanwhile, Madrid Metro users will be able to use “the intelligent keyboard for destination selection” with “natural language recognition capacity” that the devices have. They can establish a video call with the operators if they need telematic help and they can even obtain new transportation tickets to travel. Of course, we recommend that users open the umbrella. There are leaks. Photo | Madrid Metro In Xataka | 1,500 tons in weight, 100 meters long and one objective: excavate Metro Line 11 in Carabanchel

In its race to make advanced chips, China has tried to copy ASML. It’s going wrong

by

China continues to make extraordinary progress when it comes to manufacturing its own advanced chips, but it still has a big problem: it does not currently have manufacturing equipment. extreme ultraviolet photolithography (UVE) own. Of course is working in the development of this technology, and one of the strategies it is following to overcome this challenge is unique… and almost obvious. Reverse engineering. In his 2010 book ‘Copycats’ Professor Oded Shenkar argued that it is often the case that imitators end up triumphing over innovators. Although in the West the view is the opposite, in China there is a positive view of copying and reverse engineering processes are an important tool to copy technologies. That is what the country has supposedly tried, as indicated in The National Interest (TNI). From producing for the world to producing for themselves. Already we review the conclusions from the book ‘Apple in China’, which is a perfect example of how by delegating production to China, Western companies have ended up contributing to the country’s development and its specialization. The trade war has logically made China now seek its independence in the face of the vetoes it is suffering from developing its own technological solutions. From UVP to UVE. There has already been significant progress in this area, and recently we counted as a Chinese manufacturer already has a prototype of a UVP machine (deep ultraviolet) for the creation of relatively advanced chips. If there is a crucial challenge to be able to create these even more advanced chips, it is power. have UVE photolithography machinesbut having that first problem solved is important to make the leap to EUV technology. And this is where something unique has been discovered. Let’s see how it works inside. As revealed in TNI, it has been revealed that China has been “caught” trying to reverse engineer a machine ASML UVP Photolithography. Not so much to mass produce these machines, sources indicate, but because Chinese technicians are trying to learn how they work in order to replicate them and, from them, develop more advanced machines and chips. It’s not broken just because. However, it seems that when disassembling one of these ASML systems, Chinese technicians damaged it. That made them notify the official ASML technicians to solve the problem. When they arrived, they discovered that the machine had not simply broken, but that the Chinese had tried to dismantle it and then reassemble it. ASML’s de facto monopoly. ASML’s UVE photolithography machines are considered the most complex and advanced in the world, and the truth is that today the Dutch company has a de facto monopoly with such systems. It is these machines that allow access to the production of the most advanced chips – such as those used in NVIDIA’s modern AI accelerators – and have become the true bottleneck of the semiconductor industry. Beyond the damaged machine. The incident reveals two crucial points. The first, Beijing’s extreme urgency to be able to control chip production from start to finish. The second is that the challenge of creating these machines goes beyond mere hardware copying: lithography systems require extraordinary technical mastery of components such as precision optics or materials science. Too many obstacles? China may have brilliant engineers, but ASML machines also have a highly specialized supply chain which undoubtedly makes it difficult for such a machine to be built entirely in China. A good example is Zeiss SMTthe German company that supplies the ultra-precision optical systems and mirrors needed for UVE and advanced UVP photolithography systems. A long way to go. This supposed problem reveals the difficulties that China is going through in order to have machines with advanced photolithographic technologies. At Nikkei Asia They were already talking in July about how complex it is to achieve a “Chinese ASML.” In this analysis they cited Didier Scemama, director of hardware research at BofA Global Research, who estimated that China still has years to achieve something like this. “It may take 5, 10, 15 years, we don’t know. Will it be competitive with what ASML does? It’s highly unlikely, but it will be good enough for China.” Image | Zeiss In Xataka | Holland has just declared war on China in the most important battle of the century: control of semiconductors

Radars on land, conditioned by the country’s geography, do not always offer the necessary coverage against threats that seek to go unnoticed. To respond to that challenge, Seoul has decided to bet on a new generation of Early alert planescapable of expanding surveillance and ensuring more stable control of your airspace. It is not just about incorporating technology, but ensuring that the country has sufficient means to anticipate any scenario. The search for a new early alert plane It started in 2020when the Defense Procurement Agency (DAPA) approved the second phase of its AEW & C program. By then, South Korea already had four E-737 Peace Eye acquired from Boeing in 2006 and delivered in 2012, but the experience had made it clear that they were not enough. Parliamentary documents revealed in 2019 indicated Availability problems and technical failuress that prevented maintaining the planned patrol rate. To that limitation was added the pressure of an increasingly complex strategic environment, marked by the expansion of North Korean arsenal. A jump in the air surveillance strategy Seoul has opted for an unusual combination until a few years ago: an executive reactor Bombardier Global 6500 equipped with radar The/W-2085 developed by Elta. This system, with active electronic exploration antennas on the sides and additional sensors in the nose and tailallows to monitor in all directions promising a much greater scope than that of conventional radars. With this model, the country is looking for a more compact platform and with operational costs contained compared to larger solutions. The contest was marked by a struggle between two proposals that started from the same base plane, the 6500 global. L3Harris offered to integrate it with the radar the/W-2085, while the European Saab presented its globaleye solution, equipped with the radar Erieye Extended Range. Dapa’s evaluation concluded that there were no major differences in technical performance, but in other aspects. As the agency explainedthe American proposal received more points in operability, maintenance costs and contribution to the local industry, while the Swedish firm stood out in price and contractual conditions. Conceptual Image of Global 6500 for South Korea According to Dapa, the approved budget amounts to 3.87 billion wones, about 2,820 million dollarsand contemplates the incorporation of four planes until 2032. The goal is to have permanent patrols capable of monitoring the national airspace without interruption and coordinating the response in case of crisis. Deliver planning up to that horizon will progressively integrate aircraft in the operations of the Air Force. An E-737 Peace Eye in the United States The industrial component presumably had a relevant weight in the decision. L3harris has been supplying equipment to the South Korean armed forces, from electro-optical and infrared surveillance systems to safe communications and night vision devices. The company has an authorized service center in the country, which reduces maintenance times and simplifies logistics in case of breakdowns. The 6500 global is expected to reinforce the air defense of the Asian country. These devices will be integrated into the grid national Istarconnecting combat sensors and units to generate a complete image of airspace. Its main mission will be to detect intrusions and coordinate the immediate reaction, but its regular use is also contemplated in periods of calm to maintain training and preparation of crews.
