Science has measured how dinner affects sleep and the result explains why you wake up craving sugar

by

Almost everyone has experienced an annoying night tossing and turning in bed after a heavy dinner or fat. Under this pretext, science has gone one step further to demonstrate that the relationship between what we eat and how we rest is completely bidirectional, making what we eat determine whether we are going to rest better or worse. And the most surprising thing is that sleeping poorly can cause us to need to consume more sugar the next morning. A Granada studio. In February 2026 the magazine European Journal of Nutrition public a revealing investigation led by the University of Granada, where researchers monitored the habits of 146 adults with obesity. To do this, they used special watches to analyze accelerometry over a period of 14 days, to later cross-reference the activity data with dietary surveys of what had been consumed throughout the day. Prohibited items. One of the most interesting conclusions reached was undoubtedly the relationship between certain foods and poor rest. And to be clear, the elements that should be prohibited at our dinner are the following: Saturated fats. Eating excess protein and, more specifically, eating red meat for dinner. French fries, or fried foods in general, reduce the quality of sleep. Alcohol is one of the classics on this topic, since, although it generates a feeling of sleep, it destabilizes its quality. Large meals cause slow digestion and cause nighttime awakenings, preventing you from entering into a deep and restful sleep. Highly recommended foods. On the contrary, the passport to restful sleep seems to lie in another type of nutritional profile. Interestingly, carbohydrates, often demonized at night, were associated with better rest in this study. Although we are not talking about sugar directly from the sugar bowl, but rather complex carbohydrates, such as brown rice or potatoes, because help transport tryptophan to the brain. But in addition, the consumption of oily fish such as salmon or sardines is also recommended, since they are rich in omega-3 and especially tryptophan. The reasons. As we see, tryptophan is key in the diet to induce quality sleep, and it is no wonder. Biochemistry tells us that the tryptophan that we ingest through the diet is converted into serotonin and, subsequently, that serotonin is transformed into melatonin, the well-known sleep hormone. And for this chain to work we need very important factors such as vitamin B6, magnesium or zinc. But this also adds to a much less difficult digestion when talking about foods that are barely fatty and that do not require a lot of work on the part of our body and that do not invite reflux symptoms to appear that can be really annoying at night. Specific foods. With scientific support behind it We find the kiwi, since here a trial pointed out that eating two kiwis, one before going to sleep, reduces the time to fall asleep by 35%. But it also increases sleep duration by 13% due to its contribution of antioxidants and natural serotonin. Additionally, green leafy vegetables such as spinach, chard or lettuce provide magnesium and tryptophan. And if vegetables are not for you, we also have eggs, either boiled or in an omelet, which provides tryptophan and vitamin B6, along with the classic grilled chicken breast, which is also an excellent source of tryptophan. The rebound effect. However, the true clinical contribution of the research is to show that this problem is, in reality, a cycle that feeds on itself in a dangerous way. Here the researchers found that when participants experienced a poor night’s sleep, breakfast was marked by a higher consumption of sugars and a lower intake of fiber.

Samsung has made a lot of money from the memory crisis and its employees wanted their cut. Result: bonus of $340,000

by

Employees at Samsung’s chip division were in high gear. And it is logical: your company is becoming gold thanks to the rise of data centers for AI. The demand for memory chips is extraordinary and that has caused Samsung’s market capitalization to skyrocket over a billion dollars. The company, yes, was being very selfish, but the threat of a strike He has made her see reason. The bonus of the crisis. Samsung Electronics workers have ratified a multimillion-dollar compensation agreement. One that will see employees of the semiconductor division receive an average bonus estimated at 513 million won (about $340,000). Agreement in extremis. The vote was approved by 74% of members of the majority union, and was closed in extremisbecause there were 90 minutes left before an indefinite strike began that threatened to paralyze this giant’s supply chains. The risk was too high. This agreement avoids a scenario that would have been catastrophic for the AI ​​industry. Samsung is the largest memory chip manufacturer in the worldand its modules power everything from mobile phones and electric vehicles to the GPUs used in AI data centers. Considering that the market is already stressed by the memory crisis and demand that far exceeds supply, adding this bottleneck would have had unforeseeable consequences. Only Saudi Aramco surpasses Samsung in estimated operating profits for 2026. Source: Bloomberg. Memory chips are pure gold. Samsung is on its way to close one of the most profitable years in its history, and its semiconductor division already indicated that its profits had multiplied by 48 in the first quarter of the year, an absolutely extraordinary figure. She is not the only one taking advantage of this phenomenon: SK Hynix and Micron They have broken the trillion-dollar market capitalization barrier for the first time. Some so much and others so little. Although the agreement has avoided a logistical disaster, it has also caused a very uncomfortable situation internally. The bonuses are linked to the financial performance of each business unit, which means that the 28,000 members of the chip division have benefited significantly, but the rest of the company has not. The differences are clear: Engineers in that division will receive bonuses of up to 600 million won ($400,000). They will share 40% of the total allocated as bonuses. Personnel in divisions such as home appliances or telephony will receive a testimonial bonus of just 6 million won ($4,000). They share 60% of the bonus, but there are many more in number, about 260,000 in total. The average salary of Samsung employees in 2025 was 158 million won (about $105,000) according to internal company information published in March. Unions divided. This asymmetry of 100 to 1 has caused great tensions to appear between departments, and this has also been noted in the negotiation and conversations in the union. While the majority bloc (which included the majority of workers in the semiconductor division) supported the agreement with more than 80% of the votes, the secondary union, which brings together employees from other divisions, rejected the document with only 21% of votes in favor. TM Roh takes action. The situation is so worrying that TM Roh, head of the device division, has sent an internal statement to try to calm things down. He has admitted that the results of the negotiation have left thousands of employees feeling “alienated, dispossessed and hurt by the company.” Top management has promised to monitor the conditions of each unit, but while Samsung has managed to control the chaos in its factories, it could have an even more disturbing problem on its hands.

Japan is suffering a record number of ramen shop bankruptcies. And it is partly the result of the “1,000 yen barrier”

by

The ramen is almost a religion (gastronomic) in Japan. One, yes, condemned to adjust to a certain price range. Although bowls of noodles with soup, meat and vegetables are one of the symbols of Japanese cuisine and a draw for tourists, in the country ramen is seen as a modest dish for students leaving school or workers with a brief lunch break. A sort of ‘worker menu’. So much so that there is even talk of “1,000 yen wall”a psychological barrier to noodle bowl prices. The problem is that Japanese hoteliers have seen their costs increase until they are dragged into a critical situation: in 2024 they registered a record of bankrupt ramen shops and, although the situation improved significantly in 2025ruined businesses still number in the dozens. Bad season for business. That the expense sheet increases while the income sheet is conditioned by a psychological barrier that limits prices can only translate into one thing for businesses: problems. Japan’s ramen restaurants know this well, having been registering dozens and dozens of bankruptcies for years and in 2024 they even reached a record of closures. The data They come from the research firm Teikou and are eloquent. In 2020 there were 54 ramen restaurants condemned to bankruptcy, in 2021 there were 17, a figure that is largely explained by the aid given by the Government during the COVID-19 pandemic, and in 2022 the bankruptcies rose again to 33. The following year there were 53, in 2024 a record of 79 bankruptcies and last year, the latest data available, 59 stores were declared bankrupt. For their study, Teikoku technicians mainly take into account those businesses that accumulated debts of more than 10 million yen (just over 54,000 euros) and have no choice but to declare bankruptcy. The key: the trend. The figure may seem low if one takes into account that throughout the country they are distributed more than 21,000 restaurants of ramen, but it is significant. Last year, in fact, he made the weapons fly due to the record of bankruptcies. The latest data from the sector are somewhat more positive, but are still far from ideal: dozens and dozens of businesses continue to close. However, there is another reason why the figures attract attention: the discourse. Local media and international They have spent time warning of the cascade of closures. There is who warns Furthermore, beyond the balance of bankruptcies, a significant number of establishments that remain open do so in delicate financial health. That is, they remain operational, but they are not well. Struck by costs. Bankruptcy figures may vary depending on the period analyzed, but what does not vary are the analyzes that talk about the causes of the ramen crisis. The diagnosis It is clear: the problem for the stores has been the rise in costs and the limited margin to pass it on to customers. In 2025 Washington Post cited a study from Teikoku Databank that concluded that the sum of the ingredients – including pork, pasta and seaweed –, labor and energy required to make ramen had increased by around 10% in three years. Other calculations They point out that the cost per client grew by 5% between 2022 and 2023. “Prices have been rising over time, but in the last three years they have been incredible,” recognized Tetsuya Kaneko, with a location in Tokyo. The ‘perfect storm’ of ramen. Tetsuya Kaneko assumed in fact that his case was not unique and “everyone in the sector is struggling.” At the end of the day, hoteliers have been forced to deal with a ‘perfect storm’ that works against them: inflationthe rise in import prices due to the weakness of the yen against the dollar and the increase in the cost of energy that had the war in Ukrainewhich also affected the flow of cereals. For three months now, the war in Iran has been added to this panorama, which has made transportation more expensive. “The example of ramen shops illustrates economic trends well because they have a hard time passing on increased costs to end consumers,” explains to the newspaper American Norihiro Yamaguchi, economist specializing in Japan at Oxford Economics. In his opinion, until 2022, consumers were hesitant about any price increase, but the reality is now different: “They have to accept the increase in the cost of living.” For all pockets. As if the situation were not complex in itself, ramen establishments have to deal with another challenge: prices. Or rather, the image that the dish has in the country and the psychological barriers that in a certain way determine its rates. It is not something completely unknown in Spain, where a similar logic operates in the menus of the day of the restaurants. “Ramen has always been a staple food for low-income people, students… I don’t want it to be out of reach,” Kaneko explains.. The “1,000 yen wall”. A quick Google search shows several references, both on blogs and specialized websites in Japanese culture as in diaries generalistswhat is usually called the “1,000 yen wall”, which in exchange amounts to about 5.4 euros. That round number marks the price ceiling that rarely exceeds a basic noodle bowl with broth, meat and vegetables. Or so it was until recently. Faced with the new scenario and the delicate situation to which many businesses have been dragged, those in charge have had to consider a dilemma: cross the 1,000 yen barrier or resign yourself to following in the footsteps of the 72 establishments closed in 2024 and 59 in 2025. Upload with apology included. A few months ago Kaneko I remembered how in 2023 it had to increase its prices by 50 yen, reaching 1,000 for a standard bowl. Another professional in the sector, Taisei Hikage, recalled how rates have changed in a matter of a decade: if 10 years ago there were basic noodle dishes for 500 yen, today the situation is very different. When he opened his own restaurant in 2023, he … Read more

They have measured the brain age of people who usually meditate. The result is that he looks six years younger

by

The age reflected on our identity card does not always coincide with the real age of our organs. In the field of neuroscience, the “brain age” has become a fascinating biomarker to understand how our nervous system ages and what factors can protect it. And now meditation seems to have a fundamental role in delaying this clock at least during our rest hours. A new study published in the magazine Mindfulness has found that people who practice meditation At an advanced level they have a “brain age” during sleep that is almost six years lower than their chronological age. A striking fact that opens doors in the study of neuroplasticity and the role that this habit can have in the lives of many people. Although logically we must move away from the idea of ​​suffering a miraculous “rejuvenation” How it has been seen. To understand the finding, we must first understand how this “brain age” is measured, and here the researchers did not use MRIs to see the size of the brain, but instead analyzed the electrical activity through electroencephalograms (EEG) during sleep. Its evolution. Something that is known is that, as we age, the brain waves we produce when sleeping change in predictable ways. Under this pretext, algorithms have been used to calculate a “brain age index” based on these electrical patterns. With these data, if the brain produces waves typical of someone of a similar age, the index is similar to zero, but if waves are produced from someone older, the index is positive. The method. The research team evaluated 34 people who meditate at an advanced level, belonging to the discipline Inner Engineering with an average age of 38 yearsand compared their sleep records with those of several control groups who did not meditate. The result here was that people who usually meditate showed an index that corresponded to people six years younger. That is, their brains, electrically speaking and while sleeping, behaved like those of people almost six years younger, while the control groups showed values ​​close to zero or slightly positive. One more biomarker. The findings fit like one more piece in a scientific puzzle that has been years in the making. Previous research already pointed to global changes in the EEG spectrum and greater neuroplasticity, and it was even seen that regular meditation caused an increase in brain gray matter and a possible neuroprotective effect. However, from a clinical standpoint, it is critical not to confuse an EEG marker with literal rejuvenation. The fact that the brain shows younger electrical patterns at night is an excellent biological indicator of brain health, but this study does not clinically prove that meditation is a proven tool for reversing cognitive decline. You have to be cautious. In this case it cannot be categorically stated that meditating rejuvenates the brain because there may be other factors that have not been measured. We must also keep in mind that we are dealing with a study on only 34 people, so the sample should be increased with the aim of extrapolating it to the entire population.

The result is clear, alarming and there is no turning back

There is an unquestionable reality with the data in hand: In Spain it rains less now than 30 years ago. In fact, the climate has changed since the 90s: temperatures have risen, summers are longer and those rain patterns essential for activities such as agriculture or aquifer recharge are no longer what they used to be. The Spanish state is one of the regions of the planet where climate change is being seen more and better worse. In this climatic context, precipitation data tells a crystal clear story. Meteorologist Roberto Granda from Eltiempo.es has used AEMET Opendata records to draw maps that compare the average annual rainfall between the periods 1961–1990 and 1996–2025 in 71 stations with continuous data for more than 60 years. The first of these periods is not chosen at random: it is the reference climate norm fixed by the World Meteorological Organization, the global standard for detecting anomalies and trends. To distribute the values ​​between stations, Granda applied a geostatistical interpolation technique that incorporates the relief of the terrain, which makes it the most reliable method for mapping precipitation in a geography as irregular as the peninsula. The result is unequivocal: it rains less in Spain, and it is not something specific or local, but structural and widespread throughout almost the entire peninsula. In this climatic context, precipitation data tells a crystal clear story: meteorologist Roberto Granda of Eltiempo.es has used the records of the Spanish Meteorological Agency AEMET Opendata to draw maps that compare the average annual rainfall between the periods 1961 – 1990 and 1996 – 2025 in 71 stations, that is, with continuous data and for more than 60 years. It rains less in Spain and it is not something specific or local: but something structural and that affects almost the entire peninsula. Evolution of average annual precipitation in Spain. Roberto Granda with data from AEMET These first two maps collect the amount of precipitation in both time frames where it can be seen that he rain pattern continues: The north and northwest (Galicia, the Cantabrian coast and the Pyrenees) continue to concentrate the highest rainfall, above 1,500–2,500 millimeters annually, while on the other side of the scale is the southeast of Almería and Murcia, which does not reach 200 mm. But within that known pattern, absolute values ​​have fallen in practically all regions. With the data in hand, it rains less in Spain than it did 60 years ago Difference in precipitation from 1961 to 2025. Roberto Granda The most impressive map is exactly the one above these lines: the difference in rainfall between 1961 and 2025. At a glance it is clear that in almost the entire State the rain is in the red compared to 60 years ago, since the cartography is colored by beige and brown tones on almost the entire peninsular surface. The steepest falls, between 100 and 200 mm per year, are concentrated in inland Galicia, Extremadura and the central-western area. In this last area is Mediterranean aridification at its maximum splendor: the Mediterranean is one of the hot spots of climate change. Fortunately, there are some exceptionsbut they are localized: areas where the variation is practically zero or slightly positive. One of the most obvious is in the extreme northwest of Galicia, especially the Costa da Morte and the province of A Coruña, which maintains or slightly exceeds its historical records thanks to its direct exposure to Atlantic storms. Neutral or slightly greenish tones are also seen in some areas of the Navarrese and Aragonese Pyrenees, and in the corridor of southern Navarra and northern La Rioja, at the transition between the western Pyrenees and the Ebro valley. The meteorologist has also published year-by-year rainfall since the 1990s, allowing for a closer and more detailed analysis. Something that stands out considering the colors is that the variability has skyrocketed. The CSIC has an explanation: Oscillations between dry and humid extremes are precisely a characteristic of the Mediterranean climate under global warming. Precipitation per year. Roberto Granda Although the general trend is less rain, there is years that define the extremes. On the dry side, there are four years that stand out above the rest: the 94-95 biennium, devastating in the south and center of the peninsula, 2005 on the plateau or that 2012 that left reservoirs below minimum levels in half of Spain. At a quick glance, the 2017 orange draws attention: AEMET he rated it as one of the driest years since instrumental records exist. On the wet side, 96 – 97 stand out from what they had before and after, especially in the northwest and central. Also 2010 and 2013 show green and blue coverage well above the average. 2024 deserves special mention: it breaks a long streak and is the wettest year of the last decade in several basins. Of course, a wet year does not work miracles. The AEMET projections are not encouraging: this reduction in rainfall will worsen throughout the 20th century, with decreases of more than 20% in the south and southeast of the peninsula. With longer and more frequent rain events, the rain will be concentrated in more intense, concentrated and tragic events throughout the year. Because paradoxically, this pattern has consequences in both droughts and floods.

In 1985, on the verge of being defeated by Pepsi, Coca-Cola changed its ancestral formula. The result was a disaster

by

Coca-Cola had been the reference soft drink around the world for decades, but in the early 80s a very tough competitor had emerged: pepsi. The firm had been gaining more and more followers with advertisements in which they participated Michael Jackson, Michael J Fox either Cindy Crawfordand its success did not stop growing thanks to a spectacular advertising campaign called “The Pepsi Challenge”. Those ads seemed to show that people preferred the taste of Pepsi, and Coca-Cola managers, scared by the threat of being forgotten, decided to change the formula and create the so-called “New Coke.” That was a disaster and Coca-Cola ended up returning to its original formula. The Pepsi challenge was as simple as it was effective. The people who participated did a “blind tasting”: there were two glasses with unidentified cola, one with Coca-Cola and the other with Pepsi. In appearance they seemed the same, and behind them were the bottles with which each glass had been filled (or hidden under some paper cylinders). The result according to the advertisements was always himself. The taste of Pepsi won time and time again. Coca-Cola executives, who saw how their market share was constantly declining, began a gigantic project: the creation of a “New Coca-Cola” (New Coke) that would see its recipe modified for the first time since the creation of this drink in 1886. What happened The modification of the recipe was evaluated with market studies that were promising: the new Coca-Cola, sweeter, beat both the old Coca-Cola (the original) and Pepsi. Everything seemed to show that Coca-Cola had its winning drink. That made the company announce “New Coke” with great fanfare on April 23, 1985. Initially the reception was good, but criticism soon began to arrive, which increased: a lot of people wanted the old Coca-Colaand surveys conducted shortly after the launch showed how only 13% of people preferred “New Coke.” Coca-Cola ended up producing the original recipe again, which it called “Coca-Cola Classic” just two months after that launch, and some time later it directly stopped manufacturing its “New Coca-Cola” to stay with the classic, which also lost that adjective. Everything remained as at the beginning, but with a spectacular marketing failure and development in which the firm had invested 100 million dollars. Still, Coca-Cola recovered after the disaster. That attempt to compete, although a failure, seemed to resonate deeply with consumers, especially when Coca-Cola recognized its mistake and offered the “old Coca-Cola” again. By the end of 1985, Coca-Cola Classic was outselling New Coke and Pepsi. What happened? One of the problems was pointed out by Malcolm Gladwell in his book ‘Intuitive Intelligence: Why do we know the truth in two seconds?’ (‘Blink: The Power of Thinking Without Thinking’). In it he explained how the failure was in the nature of the blind tastings, based on “sips.” People, he explained, reacted positively to the sweeter taste of Pepsi when they only tried a sip, but that taste ended up being worse when you drank an entire can, and that is what according to Gladwell Coca-Cola failed to understand in its tests. The original Coca-Cola recipe proposed a much more appropriate balance for the capacity of the cans and bottles of this soft drink. At Coca-Cola they also tried to investigate what had happened, and the conclusion of those in charge was that they underestimated the public reaction of people who rejected the change. The response generated by that launch of the “New Coca-Cola” was astonishing, and signature collections and movements against the new recipe were organized that united many people in an unprecedented campaign. Of course: New Coke kept winning those blind tastings. It didn’t matter: the one that really won was Coca-Cola, whose current quota in the soft drink market is 44% in the United States, while Pepsi’s is 26%.

Someone connected an unprotected Windows XP PC to the Internet to see what would happen. The result is not surprising

by

When Microsoft ends its support for security updates in its operating systems, it is not usually advisable to use a PC with said system unless it is for a specific and specific case. Eric Parker, content creator specialized in technology, wanted try with an experiment: use Windows XP today connected to the Internet and eliminating all types of protections. As you may have imagined, the PC has become a magnet for malware. In fact, in just 10 minutes, the operating system was completely compromised. Parker also helped make this happen for educational purposes and to demonstrate how dangerous it can be to use an operating system like Windows XP today. Windows XP without firewall and without NAT 10 minutes later: a magnet for malware The expert configured a virtual machine with Windows XP Service Pack 3 on a Proxmox server, also disabling its firewall and NAT (Network Address Translation) settings and replicating the connection conditions common in the early 2000s. To recreate this scenario, the researcher Completely disabled Windows XP firewall and assigned a direct public IP address to the system, exposing the machine without any intermediate protection. As seen in the video, in just ten minutes, the system showed the first signs of infection with the appearance of the “conhoz.exe” process in the Task Manager, which turned out to be a Trojan disguised as a legitimate component of the operating system. After downloading a compatible browser and continued use of the system, in a short time we see how the PC starts to accumulate malware from multiple unknown sources. The system had been a victim of several Trojans and malicious programs running from temporary folders. He was also the victim of a rogue FTP server that allowed full remote access to files, DNS modification to redirect traffic to attacker-controlled servers, and the creation of additional user accounts for attackers to maintain access to the system. A whole string of malicious processes that ended up hijacking the PC. Image: Eric Parker The key factor that allowed the rapid entry of all these malicious components was the vulnerability EternalBluepresent in unpatched Windows XP SP3. This security breach, which was later used by the famous ransomware WannaCryallows attackers to execute remote code without any user interaction. Parker explains that tools like Nmap allow cybercriminals to scan the network for vulnerable systemsquickly identifying exposed and unprotected Windows XP computers. A system that was crying out to be violated and a Windows 7 stronger than it seems The content creator himself admits that the conditions were as optimal as possible to get malware: disabled firewall, direct connection without NAT and unpatched system. Under normal circumstances, with a basic home router and the firewall activated, Windows XP would be significantly more protected. However, the risk does not disappear completely. The use of outdated browsers and the ease of privilege escalation on this operating system remain serious problems. And as shown in the experiment, once infected, The malware was able to automatically close security tools like Malwarebytes. To contrast the results, Parker performed the same test with Windows 7 under identical conditions. Surprisingly, after ten hours of exposure, the most modern system showed no signs of infectionevidencing the significant security improvements implemented in later versions of Windows. Now that official security update support for Windows 10 is ending soon, it’s good to take a look back and see how an outdated system can easily become compromised. Fortunately, today we have many more alternatives if we do not want to update to Windows 11.

The US has invested 16 years and 8 billion dollars in renewing the software of its GPS network. Result: a failure of epic proportions

by

The Next-Generation Operational Control System project (OCX) was going to modernize the constellation of the United States’ more than 30 GPS satellites. The company RTX Corporation (previously known as Raytheon) managed to win the project in 2010 with a budget of 3.7 billion dollars. The project was supposed to be completed in 2016, but in reality the US has spent $8 billion and 16 years later has an absolute disaster on its hands. 16 years of broken promises. In 2010 the iPad had just appeared on the scene and cloud computing was a somewhat diffuse concept. The project of the US Government was reasonable, and proposed that the OCX system be operational by the time Lockheed Martin’s new GPS III satellites debuted. The development became a chaos of bugs and requirements changes, and to this day it is unclear when, if ever, it will be completed. In Xataka 90% of Iran’s oil industry depends on a tiny island. One that is already on the radar of the US and Israel A fortune invested. The financial management of the project is the first big disaster. The initial budget was estimated at 1.5 billion dollars, but since the award until today that figure has risen to reach almost 7.7 billion of current dollars, to which another 400 million are added to support an improved version of the satellites, the GPS IIIF. This increase is not due in large part to the project suddenly being much more ambitious or more capable, but rather to the costs of having been fixing everything that has gone wrong since they started working on it. Software costs more than satellites. Every time software fails an integration test, the bill runs into tens or hundreds of millions of dollars. That has made the OCX system one of the most expensive and least efficient software projects in recent US military history. In fact, it far exceeds the cost of the satellites themselves that it had to control: the 22 GPS III satellites of the contract signed in 2018 have a budget of 7.2 billion dollars. Satellites of the future controlled by a fairground shotgun. Currently the United States has a fleet of GPS III satellites in orbit capable of emitting much more powerful “M-code” signals and interference resistantsomething that among other things allocates them especially for military applications. The problem is that since the OCX software not workingthey are managing them with control systems inherited from the 90s. It is as if we had a VHS video connected to watch movies on an 8K Smart TV: the potential is there, but one of the components is an absolute bottleneck. {“videoId”:”x8wlh9q”,”autoplay”:false,”title”:”United States vs. China: The CHIPS WAR”, “tag”:”webedia-prod”, “duration”:”1611″} The cybersecurity nightmare. One of the big problems of this project has been the cybersecurity requirements. OCX was designed to resist cyberattacks from powers such as Russia or China, but that requirement has become a spectacular technical burden. Pentagon standards have evolved so quickly that they have not been able to be adapted to an architecture that begins to become obsoleteand covering successive patches is locking the system in a complex vicious circle: the software is never finished because more and more vulnerabilities appear. Failed tests. The latest report from the Government Accountability Office (GAO) has been the final straw. During the tests the system again showed once again instabilitywhich has forced the final delivery to be delayed to the end of 2026 or even 2027. Frank Calvelli, of the Air Force, has expressed his dissatisfaction with that unacceptable management of private industry: the strategic advantage that this project should offer at a time like this is inaccessible due to the disastrous progress of the project. It’s not that difficult. for a long time the excuse for justify the delays was that OCX was “the most complex software ever created for space,” but other players in the sector have shown that achieving these types of technical milestones is possible. SpaceX has demonstrated this with technical “miracles” like its reusable Falcon 9 or with the development of Starship, for example, so those arguments are falling on deaf ears now. Waiting for a better GPS. These problems also affect us end users, who will not be able to enjoy the L5 signals for now. This much more robust frequency will significantly improve accuracy in urban centers with many tall buildings. The irony is tragic: we cannot use extraordinary space infrastructure because the base stations cannot cope with it. While waiting for the problems to be resolved, the learning is clear: the software cannot be a monster that takes 16 years to build In Xataka The GPS in the Baltic has been experiencing interference for months and the culprit is becoming increasingly clear: Russia And while as always, China. While the US crashes against its project to renew the GPS constellation, China has once again managed to “become independent” from Western technology. Your satellite navigation system Beidouit does not replace GPS, true, but It already complements it in 140 countries. Once again China’s long-term view has its obvious result: it has taken 20 years in deploying its constellation, but they already surpass the GPS system in metrics such as signal availability or integrated messaging services. Europe, by the way, also has its own alternative.

China has just become the first country in the world to mass produce T1200 grade carbon fiber, the strongest synthetic material ever manufactured on an industrial scale. The milestone is led by the state group China National Building Material Group (CNBM), which presented it on March 11 at JEC World, the most important composite materials fair in the sector, held in Paris. We tell you all the details. What exactly is the T1200. In the world of advanced materials, the number that accompanies the T is a tensile strength rating. The higher the number, the stronger the fiber. T1200 has a resistance greater than 8 gigapascals (GPa), ten times more than conventional steel, and yet its diameter is ten times smaller than that of a human hair. Chinese media CCTV exposed the example that a rope less than two millimeters thick, made from 120,000 twisted T1200 filaments, is capable of towing a bus with 54 adults on board. And it weighs a quarter as much as steel. dhe laboratory to the factory. Zhou Yuxian, president of CNBM, counted that it has taken the country about 20 years to move from its research and development to mass production. The plant has a projected capacity of about 100 tons per year. Compared to that of Toray Industries, the Japanese company that leads the global market with 29,100 tons per year, it is laughable. But be careful, Toray announced in 2023 that it had developed its own T1200, also with 8 GPa resistance, but to date they have not offered details about a supposed mass production. China has beaten them to it. Mbeyond engineering. Industrial carbon fiber is a material that can be used for endless applications: from civil (aeronautics, electric vehicles, hydrogen storage, drones, medical devices, elite sports equipment) to military (fighter aircraft, missiles, satellites, fuselage structures). Precisely for this reason, Japan and the United States They have been strictly controlling their exports for decades through mechanisms such as the Wassenaar Agreement. China, which for years has depended on imports or has been forced to obtain the material through alternative means, just remove that dependency. The same has happened with semiconductors, since the foreign blockade has served to amplify their technological self-sufficiency. How China has accelerated in just a few years. Toray launched the T300 in 1971 and took 43 years to introduce the T1100. China didn’t have its own T300 until 2008. However, in just over a decade it has climbed from the T300 to the T1200, a cadence that the entire industry is watching closely. The key has been a model that China has already demonstrated with previous grades of this material: combining state capital, university research and industrial capacity in the same ecosystem, with continuous improvement cycles until reaching mass production. Who else competes in this race. The global carbon fiber market is an oligopoly with few relevant players. Mitsubishi Chemical (Japan) advertisement in December that it plans to double its production capacity in Japan and the United States between now and 2027 for sectors such as aeronautics and supercars. The South Korean Hyosung Advanced Materials aims to reach 24,000 tons per year in 2028. On the other side of the globe, Hexcel, an American composite materials company, defines itself as the world’s largest producer of aerospace carbon fiber and the main supplier for United States military programs. But the geographical trend has already changed. And according to the report Future Markets’ Global Carbon Fiber Market published in February, Asia-Pacific has surpassed North America and Europe as the world’s largest consuming region.

Meta spent a fortune on AI talent and data centers. Nine months later the result is: zero models

by

Mark Zuckerberg wanted to be the Florentino Pérez of AI. last summer began to sign galacticos in this segment and getting talent by letting go stacks of millions of dollars. He more popularOf course, it was the AI wunderkind Alexandr Wangwho became leader of its “Superintelligence” division. The funny thing is that the months go by and go by and in Meta they don’t seem to have absolutely anything to show. And that is very worrying. Delays. Despite having invested billions of dollars in that restructuring of the company to bet (practically) everything on AI, three internal sources confirm that Meta finds it very difficult to meet the planned deadlines. The race for generative AI waits for no one, and at the company headquarters nerves are on edge because the roadmap is not being met. Avocado, where are you? The new foundational AI model that Meta has been working on for months has been internally named Avocado, but at the moment it is not measuring up, something that reminds us what happened to Llama 4. Internal tests reveal that although it manages to surpass the aforementioned Llama 4 and the old Gemini 2.5, it falls short of Gemini 3.0 (and of course, the recent Gemini 3.1). Patience. Coming out with a model that is clearly worse than its rivals does not make sense, so Meta has decided to wait and delay the launch of its model. Avocado is expected to hit the market in May at the earliest. And meanwhile, Gemini. The situation is so critical that according to these sources, the leaders of the AI ​​division are considering something unthinkable: paying a license to Google to be able to use Gemini in their own products, something that for example will Apple do Siri. That would be a clear sign that for now this own model is not capable enough to power the AI ​​functions of WhatsApp, Instagram and Threads. Money does not equal speed. The company has spent billions of dollars on AI researchers, and has committed to invest 600,000 million dollars in building AI data centers. In January, Meta projected a capex of $135 billion dedicated almost entirely to these projectsalmost double the $72 billion it spent last year. Despite these investments, the company is currently missing from an area in which its competitors continue to advance. Internal tension. According to these sources, Meta is becoming a tinderbox. The “TBD Lab” (for “To Be Determined”), the unit led by Wang, is working under maximum pressure on models named after fruits (Avocado, Mango, Watermelon), but has clashed with old-school Meta managers like Chris Cox and Andrew Bossworth. The company is trying to integrate those models with Meta’s advertising business, which is what supports everything, but Wang doesn’t seem to handle that part of the business very well. Goodbye to open models. Meta stood out at the beginning of this AI race as the company whose open models —not Open Source— were above the rest. Llama became the norm in this area, but in this new stage that philosophy seems to change and China is the one that now leads that segment. Thus, there is talk that both Zuckerberg and Wang lean toward closed models, such as those of OpenAI (GPT) or Google (Gemini). This allows you to have full control over the code, a competitive advantage that Meta does not seem to want to give up. Few fruits of this tree. Despite the extraordinary deployment of resources, the current balance is poor. Meta’s only tangible product of those investments is Vibes, an application similar to Sora that has not managed to fully gel. Meanwhile, those initial talent signings have turned into abandonments: the trickle of AI researchers who leave the company to join others (or found their own projects) is increasing.
