why drinking a Diet Coke in the middle of 2026 is an impossible mission

by

Any consumer who has recently walked through the soft drinks aisle in a supermarket will have come across a particular scenario: the word “light” (or “diet”, depending on the country) is conspicuous by its absence. Instead, a tide of “zero label” cans and bottles dominate the shelves. Everything indicates that the iconic Diet Coke is in the doldrums. However, it is enough to look at social networks to discover a little resistance. Among young people of Generation Z, this drink has not only not disappeared, but has become a true object of desire and a lifeline against work stress. And to make matters worse, in the middle of 2026, opening one of these cans has become almost a miracle due to a geopolitical and logistical crisis that is suffocating the world. What is really happening with the Diet Coke? The rise of “Zero” At the beginning of this decade, the industry left the word “diet” for dead. “No Gen Z person wants to be on a diet these days,” sentenced in 2021 Greg LyonsCEO of PepsiCo, illustrating what seemed like a definitive change in mentality throughout the industry. Corporations assumed that young people associated the term with strict regimes or deprivation, while the designation “zero” offered a much cleaner profile. As a result, The Coca-Cola Company has put all its financial muscle behind its Zero variant. The financial data they confirm it: during the third quarter of 2025, Coca-Cola Zero Sugar experienced an impressive 14% growth. In contrast, the Diet Coke (either Diet Coke) barely expanded 2%, driven almost exclusively by demand in North America. On a technical level, the difference between the two is not a myth. As detailed in the German media RNDthe Diet Coke Original has a slightly different flavor than classic due to its specific blend of artificial sweeteners (aspartame and acesulfame K) and flavorings. The Coca-Cola Zeroon the contrary, was formulated years later with the explicit objective of imitating the brand’s original flavor as closely as possible, attracting an audience that was fleeing the stigma of “regime” products. Welcome to the “Fridge Cigarette” But Internet culture has its own rules, and corporations don’t always dictate trends. Far from dying like a drink for the generation boomerthe Diet Coke experienced a brutal organic resurgence from 2023. It all started with viral trends that invited you to “marinate” the can in the refrigerator for days to enhance its bubbles, and reached its peak when superstars like Dua Lipa showed on TikTok how they mixed the drink with pickle juice and jalapenos. This fervor led to a new concept that has taken the internet by storm: the fridge cigarette (or “refrigerator cigarette”). Young people have adopted the act of opening a can of Diet Coke cold like the modern equivalent of going out for a cigarette. For Generation Z, the metallic sound when opening the ring emulates the spark of a lighter. It’s not about nicotine, but about the ritual: a perfect excuse to get up from your desk, get away from the screen and claim a little break in the midst of modern hyperproductivity. It is an act of self-care disguised as rebellion. The company, of course, was quick to notice. Sue Lynne Cha, vice president of marketing at Coca-Cola, recognized this rebirth among young people, leading the brand to invest heavily in this renewed popularity. They launched campaigns very focused on Generation Z, such as “Love language” and “Know The Signs”, the latter narrated by comedian Kristen Wiig, encouraging workers to take a #DietCokeBreak. To sustain this momentum, the company injected an additional $18 million into advertising in 2024 alone. The “Black Swan” of 2026 Just when the Diet Coke crowned as the status symbol of work breaks, geopolitical reality dealt it a lethal blow. Right now, the world is facing an unprecedented raw materials crisis. The Third Gulf War has blocked the main sea routes of the Middle East, a region that concentrates almost 9% of the global aluminum supply. This bottleneck has generated a deficit of two million tons, skyrocketing prices and forcing European smelters to declare “force majeure” situations. How does this affect the “refrigerator cigarette”? Directly on the waterline. No aluminum, no cans. The shortage is so severe that in regions like India—where Diet Coke sold exclusively in this format—the drink has almost completely disappeared. According to FortuneIndian entrepreneurs have capitalized on this drought by organizing clandestine themed parties where admission is charged and coveted cans are raffled off, turning the Diet Coke in a true luxury item. This desperation is not trivial in a country where, according to the Indian Council of Medical Research, almost 10% of the adult population is diabetic and depends on sugar-free options to indulge. An effervescent mixture Added to this cocktail of logistical scarcity and network fanaticism is the eternal debate about health. Historically, cola drinks have been in the medical spotlight. Specialized portals such as WebMD and Medical News Today They constantly warn about the risks associated with these soft drinks, linking them to insulin resistance, increased visceral fat and even arguing that the dopamine spike they generate in the brain is comparable to that of highly addictive substances. With the version lightthe focus is on its sweeteners. a study published in Cell Metabolism suggests that aspartame could be harmful to cardiovascular health in mice, although the European Food Safety Authority (EFSA) and other experts have remained skeptical of this methodology, reaffirming that normal doses are safe. And what do new consumers say about this intersection of medical accusations? Which doesn’t matter exactly the same to them. Unlike the millennials Obsessed with wellness, Generation Z embraces this drink with an almost nihilistic attitude, driven in part by a 2000s nostalgia that has resurrected old aesthetic standards. As Andrea Hernandez, founder of the newsletter, explained Snaxshot, to The New York Timesthe mentality is: “Oh, aspartame is terrible for you… I absolutely don’t care.” It is an affordable vice, a small transgression in a world full … Read more

AMD has made a decision that until now seemed impossible

by

Lisa Su, AMD’s CEO, visited Samsung’s campus in Pyeongtaek, South Korea, in March. At that time, some Asian media considered the possibility that the purpose of this visit was to negotiate an agreement. about 2nm node from this semiconductor manufacturer. And it has just been confirmed: according to DigiTimes AsiaSamsung is going to manufacture 2nm chips for AMD. We still don’t know for sure what products these will be, but they will possibly be next-generation processors. EPYC Venice and Summer. Venice will incorporate Zen 6C cores and will be able to integrate a maximum of 256 cores distributed in eight CCDs (Core Complex Die). An important note: CCDs incorporate the cores and the cache memory subsystem, among other essential elements of the CPU. On the other hand, the EPYC Verano processors will arrive in 2027 and will work hand in hand with the Instinct MI500 GPUs in data centers to artificial intelligence (AI). Curiously, when AMD presented the EPYC Venice family in April 2025, it announced that TSMC would manufacture these chips in its 2nm node. Nvidia dominates the AI ​​GPU market, but AMD is doing increasingly better in this sector. And the company led by Lisa Su has closed the first quarter of 2026 with revenues of 10.25 billion dollarsa figure that represents an increase of 38% compared to the same period in 2025. Its data center division has invoiced 5.8 billion dollarswhich represents a growth of 57% compared to the same stage last year. These figures reflect an unappealable reality: sales of EPYC processors and Instinct GPUs are growing. TSMC can die of success The agreement that AMD and Samsung have agreed upon has arrived just a week after the leak that maintains that Apple is exploring the possibility that Intel and Samsung manufacture the advanced chips for their devices in the US. In all likelihood, the loss of influence and priority in the TSMC production chain that it has maintained for more than a decade has led to this decision. Now Nvidia has these privileges. The agreement that AMD and Samsung have agreed upon does not imply that Lisa Su’s company will stop being a TSMC client Whatever the agreement that AMD and Samsung have agreed upon, it does not imply that Lisa Su’s company will stop being a TSMC client. At least not in the medium term. In all likelihood, what AMD is looking for is to diversify and increase its production capacity in a context in which Nvidia and Apple largely monopolize TSMC’s 2nm nodes. The latter are so in demand not only by Nvidia and Apple, but also by Qualcomm, Google or AMD itself, that they cannot cope. TSMC is doing very well, there is no doubt, but everything seems to indicate that its inability to satisfy the demand of its most advanced nodes is going to cause it to lose certain orders from some of its customers. Of course, Samsung has a big challenge ahead to build customer loyalty and attract more chip designers to its 2nm nodes. Currently the per wafer performance of its 2nm nodes ranges around 55%so it is below the 60% threshold that needs to be reached to ensure node profitability and attract more customers. The per-wafer performance of TSMC’s 2nm nodes, however, ranges between 60 and 70%which places this Taiwanese company, which is Samsung’s biggest competitor and the leader of the chip manufacturing industryin a very favorable position when it comes to attracting new clients.

With the RAM market impossible, the inevitable happened: counterfeit DDR5 tablets

by

Make a reference to ‘The Simpsons‘At this point it’s complicated because the new generations may not get it, but there is an episode in which Springfield declares the dry law and, when they knock it down, the mayor asks the mafia how long it will take for alcohol to flood the city. The answer: five minutes. And that is exactly what is happening now with the RAM memory: where the market does not reach, counterfeiters enter Because after the DDR5 memories that are really DDR2 come the DDR5 memories with plastic chips. In short. The truth is that I did not imagine that we would reach a point where there would be well-crafted scams with all the intention of deceiving buyers of a RAM memory stick, but the truth is that we have been there for a few months. It was at the end of 2025, at a time when the RAM crisis was beginning to tighten (but it was far from the current moment) when it was reported that an Amazon Spain buyer received a kit of supposed DDR5 memory from Ireland that was nothing more than a DDR and DDR2 chip with a sticker on top. It was quite tacky, but you realized it instantly and you could always claim a refund because Amazon covers it in these cases. The problem is that there are scams that may be a little more ‘worked’ and that involve unsoldering the chips from a RAM tablet and replacing them with plastic parts. This is what, as we see in Digital Trendshas just happened to some users in Japan, who report the sale of memory tablets that do not correspond to previous generations, but are carefully designed to appear to be legitimate RAM when, as we say, it is a PCB with imitation chips. Or directly the entire pill being fake. An example of an auction stick ram. He original message It has moved a lot on Twitter and describes a full-fledged scam. Through stores like Yahoo Japan, users sell used RAM sticks as “junk” or “untested” in batches and at affordable prices. This is a practice that is also done with processors that we can find in stores like Wallapop and it may work… or it may not. That is why there are those who risk buying. In this case, a frog came out. The SO-DIMM modules (for laptops) had stickers that looked legitimate from Samsung or SK Hynix, but were nothing more than labels cloned from real memories used to cover the supposed chips. Instead of being DRAM memory as such, these are modules made of fiberglass that obviously do not work. In some cases, there are real circuits, but they correspond to lower-grade recycled chips. The important thing is that, be it one case or another, it is obviously not what you are paying for, but they are made well enough so that a person without knowledge cannot identify why the new memory module they have paid for does not work. Even a quick inspection can fool someone who has changed a few of these pads. It is no longer that they clone real stickers with their serial number and so on, but rather the dedication to produce those fiberglass “chips” screen printed like a legitimate one. One supposedly made by SK Hynix Another from Samsung (with SK Hynix chips, curiously…) One of the chips made with fiberglass Meteoric. Unlike the December 2025 fake RAM case, these pills are being sold in auctions on Yahoo Japan and there are already users with the fly behind their ear, which causes them not to bid and the modules to no longer be sold. But in the end it is the consequence of a market that is really impossible and in which scammers enter with promises of components at better prices than those we can find on the market first-hand. Because building a PC today is extremely expensive due not only to RAM that has been able to increase up to 400% in some cases, but for some SSDs that have also explodedgraphics cards that are beginning to be scarce and segments such as processors and the motherboards that are moving to the hoarder we’ve been talking about for months: AI hyperscalers. As I say, with prices through the roof, scams appear. with head. And (again, I didn’t think I had to give recommendations to avoid falling into a scam when buying a RAM pill), the important thing here is to have common sense. It really is like any other scam attempt: if the thing is too good to be true, we have to tune our antennas to see if they want to sneak it in. The first thing is to buy in stores and platforms that provide certain guarantees to the customer, but also look closely at the photos, compare serial numbers and ask for more photos from the seller if we are not 100% sure. And if the price is very good and we are not convinced by the explanation that the person may not know the market situation, ask as much as possible and do not trust the first thing they tell us. The RAM with a sticker that appeared in December last year. Image from VideoCardz. In the end, it is curious, but buying second-hand memory pills can become something that validates criminology, just like buy retro games on cartridge through Wallapop.

End-to-end encryption is a great idea and that’s why it’s almost impossible to understand why Instagram removes it. Almost

by

In an era where many users may be concerned about their privacy and looking to ensure their conversations are as secure as possible, Meta has made a curious move. On May 8, as planned, instagram removed end-to-end encryption in direct messages. The big question now is no longer how to communicate safely but something deeper: what interest Meta may have in those conversations. And AI leads the first suspicions. In short. Although it may seem contradictory, Meta is a company that has shown some concern about allowing the user to have secure private conversations. WhatsApp has been using end-to-end encryption for years and, although It took longer to arrive than desiredFaceBook and Instagram also implemented it for direct messages years ago. Simply put, end-to-end encryption (E2EE) is a technology that ensures that only the sender and receiver can read chats. There are applications that implemented it by default (WhatsApp), but on Instagram it wasn’t like that. It is the user who had to activate it and, if done, automatically and transparently for the user, the device blocks the message using a unique key that prevents anyone other than the recipient from accessing the conversation. It’s over. Download your messages. As we say, it has been on their support blog where Meta has confirmed that end-to-end encrypted messages are no longer available on Instagram. Since last May 8, in fact, and if you have a chat that was protected in this way, a message will appear with instructions to download the messages and keep them safe in case you want to do so. Pressure. The end of this security feature has not been accompanied by a reason why Meta abandons this feature, but it is clear that the company has not done it simply for the sake of it. A few weeks ago, when the company’s plans were announced, a Meta spokesperson told Guardian that “very few people were choosing to send end-to-end encrypted messages.” That was the main reason they cited for stopping service, but you don’t have to scratch the surface too hard to find shadier reasons. For example, different police agencies (Interpol, the United Kingdom National Crime Agency or the FBI) ​​have been pressuring FaceBook to grant them access to encrypted messages. Because of course, this technology is very useful for all of us who value privacy, but it also gives wings to those who want to use it for much darker purposes. There are organizations that have criticized the implementation in apps like Instagram because they point out that, although it is useful, if the company does not implement adequate security measures, it can intensify acts of child sexual exploitationterrorism or giving rise to violent extremism. In fact, the UK government has been searching that Signal, Telegram, WhatsApp or iMessage open or end with that end-to-end encryption. And Apple has had a media battle against the FBI for that very reason. The suspicion. But of course, for a company that has been promoting the discourse since 2019 that encryption in its applications was the way to follow to protect users, this movement seems strange and there are already those who point to more practical reasons for Meta than, simply, to please governments. Those reasons are the ability to train AI. Because if there is no encryption, there is nothing hidden. And, although there is no human reading (although it seems increasingly evident that behind the AI there are humans labeling what our video devices and voice see and hear), having access to the conversations of millions of users allows the algorithms to continue training with the aim of offer advertising more personalized (something that Meta has become very aggressive about in recent months) or chatbots that can continue drinking the Internet. It’s not such a crazy theory.. WhatsApp. “Anyone who wants to keep messaging with end-to-end encryption can go to WhatsApp,” is Meta’s own recommendation and something they said both in statements to The Guardian and on their support page. Because for their communication app they do continue to aggressively push that argument of “express yourself freely with end-to-end encryption”, “show yourself as you are, speak freely” and “no one else has access, not even WhatsApp”. Seeing that the company maintains this encryption on WhatsApp, but not on an Instagram that is increasingly a bazaar, makes the opinion that they withdraw end-to-end encryption based solely on government pressure lose some weight. In any case, as Meta itself says, if you want privacy in your conversations… you will have to go to WhatsApp. Or to any other app with end-to-end encryption.

we have just discovered that it contained a material ‘impossible’ for physics

by

In July of last year an academic investigation shook materials physics with an unexpected protagonist: a space rock collected in Germany three centuries ago. Inside it housed a mineral whose thermal behavior does not fit into any known classification. The most disconcerting thing is not the material itself (that too), but that it had been gathering dust in a glass case since 1724: no one had looked at it with the appropriate instruments until now. The meteorite of 1724. Called the “Steinbach meteorite” after the German region of Saxony where it fell. The remains quickly joined museum collections due to their exotic origin and beauty, without attracting special attention from the scientific community. Among them, in the National Museum of Natural History in Paris, where the fragment that was used for this research is located. What that fragment contains is meteoric tridymitea form of silicon dioxide extraordinarily rare on Earth. It is a polymorphism of quartz that is only generated under extreme conditions of temperature and pressure, conditions that do not occur in ordinary terrestrial geology, but do occur in meteorite impacts or volcanic environments. Why it is important. In a phrase: because of its properties. The tridymite from the Steinbach meteorite maintains a practically constant thermal conductivity between −193 °C and 107 °C (80 and 380 kelvin), something that beyond meaning that it conducts heat the same whether you are in the cold winter of Iceland or in a heat wave in the desert, it has a peculiarity: no known material behaves like this. This thermal stability is a rarity in itself in materials technology and gives it clear applicability for thermal management: it allows designing electronic devices that do not overheat and aerospace insulation systems with an efficiency unthinkable under the laws of classical physics. Context. In 2009 the physicist Michele Simoncelli together with Nicola Marzari and Francesco Mauri developed a unified equation based on the Wigner transport formalism capable of simultaneously describing the thermal behavior of crystals, glasses and any intermediate state. That equation theoretically predicted the existence of materials with temperature-invariant thermal conductivity like this one. The problem is that no one had found that material in the real world. In the universe, most minerals form under Earth’s pressures and temperatures that force atoms to adopt standard crystal lattices. But in the asteroid belt, the remains of distinct protoplanets undergo cooling processes and catastrophic collisions that generate mineral phases that do not exist naturally in the Earth’s crust. Tridymite is common in volcanic rocks, but this one of meteoric origin has the advantage of having been thermally stabilized in space for millions of years. Something doesn’t add up. Until now, science assumed that a solid material must be either a crystal (ordered structure) or a glass (ordered structures) and its thermal properties depended on that structure: the thermal conductivity of a crystal decreases with increasing temperature because the vibrations of the crystalline lattice (the phonons) disperse among themselves with more intensity. Just the opposite happens in glass because its internal disorder facilitates additional ways of transmitting heat when heated. They are opposite trends, robust and well documented experimentally for decades. The Steinbach meteorite breaks the rules and behaves like both at the same time. Steinbach meteoric tridymite has an atomic structure that presents order in the chemical bonds like a crystal and geometric disorder in the arrangement of those bonds like a glass. This combination generates an exact compensation between both transport mechanisms, the propagation mechanism (typical of crystals) and the tunneling mechanism (typical of glass), which is what the research team calls PTI conductivity, propagation-tunneling-invariant. How they discovered it. The discovery it has been possible thanks to thermoreflectometry, which measures variations in the optical reflectivity of a surface when it is thermally excited with a pulsed laser, allowing thermal conductivity to be inferred with high resolution. What they saw was that the silicon atoms were not in perfect rows, but they were not random either: they followed a “middle-range order” sequence that previously only existed in mathematical models, confirming point by point the predictions of the Wigner equation. Yes, but. The Meteoric tridymite is disruptive in materials technology, the problem is reproducibility and scarcity. So far we have only found this material in the Steinbach meteorite, a limited sample of an astronomical milestone that occurred three centuries ago. Obtaining it from meteorites is simply not feasible and the challenge of manufacturing this glass-crystal synthetically is not exactly small. A curiosity: the paper explains that in the Gale crater Martian tridymite has also been detected, raising questions about how it has influenced the geological history of the red planet or opening the possibility of eventual space mining. On the other hand, and although it is true that the material defies the laws of physics, it is important to highlight that we are talking about current physics: it is not that the laws were false, it is that they were simply incomplete.

Renfe has found a new way to make life impossible for Ouigo and Iryo. And it has nothing to do with lowering prices.

by

Renfe maintains a hidden war with Ouigo and Iryo. Beyond the headlines and the exchanges of more or less high-sounding statements, the Spanish company and its rivals fight on all types of grounds. Also outside the train tracks and the most obvious sources of business. And here, the use of workshops has a lot to say. What has happened? Renfe has prevented Iryo from using its workshops so that the company can carry out heavy maintenance on its trains. The information is brought The Economist and it states that the Spanish company has rejected Italians’ access to its facilities because they consider that the activity to be carried out there exceeds the obligations they have towards their rivals. In Xataka We have contacted both companies but as of this writing we have not received answers to our questions. The obligations. Although the facilities belong to Renfe, the Spanish company has the obligation to allow access to its workshops at specific points in Spain so that Ouigo and Iryo can carry out their maintenance operations. However, this obligation is limited to light maintenance, known in the sector as “level 1” maintenance. This scale of what falls within “light” or “level 1” maintenance and what are “heavy” or “level 2” maintenance interventions are those that have been questioned by Renfe. The company is clear, Iryo wants to carry out operations of this second category and they are not obliged to give access to their workshops for this type of tasks. The CNMC. Given the denial of access to the workshops, Iryo went to the CNMC to mediate the matter. The National Markets and Competition Commission ruled in March that Renfe had to give Iryo access to its facilities where Hitachi employees would carry out maintenance services on Iryo trains. Although Renfe, Iryo and Hitachi seemed to have reached an agreement for the latter company (manufacturer of Iryo trains) to carry out maintenance at Renfe facilities, the Spanish company indicated that this could not be carried out because heavy maintenance activity related to Renfe trains had skyrocketed and there was no space left for such actions. Given this situation, Iryo requested provisional measures from the CNMC to access “an operational pit at BMI La Sagra or, subsidiarily, at BM Santa Catalina, on a self-provision basis, for the execution of heavy maintenance (R2) of the ETR 1000.” An access that the CNMC decided to give. The reasons. The CNMC pointed out in its resolution that denying Iryo access to the workshops directly damages the business plans that it has for our country since it would force the trains to be taken to Italy to undergo said heavy maintenance. For Renfe, this should not be a problem but the CNMC rejects this position of the Spanish company. Iryo trains approach the mileage limit before passing through workshops for a thorough inspection. When Iryo arrived in Spain, it stated that it would have its own workshops where it would carry out its maintenance. However, this has not occurred. However, the CNMC forces Renfe to provide access to its facilities to carry out these tasks, with the rates that were negotiated in the summer of 2025. Not compliant. In clear rejection of the CNMC’s decision, Renfe requests the Contentious-Administrative Chamber of the National Court to stop this decision and asks the CNMC to quarantine the decision until the National Court confirms what measures should be taken. The National Court, however, does not find it serious enough to apply precautionary measures, although it does confirm that it is opening a file to study the matter in depth. With this decision, the CNMC remains firm and once again forces Renfe to make way for Iryo trains in its workshops so that Hitachi workers can carry out scheduled heavy maintenance. It’s not the first time. Although we have talked about Iryo so far, the truth is that Renfe is not the first time that it has denied entry to its workshops to one of its rivals or, at the very least, has put up all possible impediments. In October of last year, the situation was very similar although, on that occasion It was Renfe and Ouigo who led the conflict. The reason was the same, according to Renfe the activity that Ouigo wanted to carry out in his workshops exceeded his company’s obligations to lend its facilities to carry out light maintenance. The fight between the three companies is tough because if Iryo and Ouigo do not get access to the Renfe workshops, they have to send their trains to Italy and France, respectively, where they do have their own workshops. That, of course, temporarily takes some of its trains out of circulation, which undoubtedly benefits its competitors.

Einstein told us how to do it, engineering tells us it’s almost impossible

by

After the success of Artemis IIscience already has its sights set on the colonization of the Moon or Mars. The problem is that, for this to be possible, it would be necessary to develop technologies that do not exist today. For example, you can spend a short time under the effect of microgravity, but if someone wanted to spend very long stays in space, much longer than those of the International Space Station, they would need artificial gravity generation systems. If not, your health could seriously deteriorate. And how is that gravity generated? Theoretically we know it, the problem is getting it. Einstein gave the first clues. In his Theory of Special RelativityEinstein described something known as the equivalence effect, which stated that gravity and acceleration are indistinguishable effects when they have the same value. That is, since the force of gravity on Earth is 9.8 N, equivalent to an acceleration of 9.8 meters per second squared, if an astronaut traveled in a spacecraft that ascends with an acceleration of 9.8 m/s², he would feel his feet clinging to the ground, even without gravity. For this reason, all theoretical projects to create artificial gravity are based on this principle. Too much fuel. One option would be the example we have seen. A rocket accelerating at 9.8 m/s². The problem is that to maintain this figure constantly unfeasible amounts of fuel would be needed. It is not something feasible. Better spinning. Given the technical impossibility of the first option, all projects aim at centripetal acceleration. That is, the acceleration that a rotating body maintains. If we were inside a ship that rotates with a centripetal acceleration of 9.8 m/s², we could imitate gravity. But there is a problem. Centripetal acceleration is equal to angular velocity squared times the radius of the spin path. As if it were the spoke of a bicycle wheel. Angular velocity is the speed at which that object rotates. If the radius is small, a very high speed is needed to achieve a given acceleration. And of course, the people inside that circular ship would end up very dizzy. On the other hand, in very large ships it would not be necessary to turn so quickly. Therefore, for a small ship it would not be viable, but perhaps something like this could be achieved if a new space station is built in the future. In fact, There is a project to build a luxury hotel in the space that would be shaped like a giant wheel. It would be constantly spinning, with the exact radius and speed to mimic the effect of gravity. Doesn’t anyone think about the Moon? The objective of lunar bases is that their inhabitants can be directly perched on the selenite surface. The same would happen with the Martian bases.. They would have to be on the surface. Therefore, it would not be viable to be inside a flying wheel. On the other hand, a wheel could be built to which the lunar colonizers would go from time to time. Just enough to reverse to a certain extent the harmful effects of microgravity. It would be like a kind of microgravity spa. This is something that a team of scientists from Kyoto University has already designed. They have named it The Glass. The consequences can be very serious. When we are not subjected to gravity, body fluids can travel to the headcausing brain inflammation and vision problems. This also affects the circulatory system, as it can increase pressure in specific vessels, such as the jugular vein. Even the heartbeat would be affected. On the other hand, by not needing to be in a rigid posture, the muscles gradually atrophy and the bones lose density. All this without counting possible neurological, balance or intestinal problems. Long stays in a microgravity situation are unfeasible, so it will be necessary to have a clear project to develop artificial gravity. If we want to live in space, we will really need it.

LaLiga’s massive IP blocks are making life impossible for users, companies and developers. So you can claim

LittleCranky67, which is the alias of our protagonist, didn’t know what was happening with his computer this weekend. This developer was doing something that never gave him any trouble: working with the GitLab platform to download a Docker software package. That process kept giving him strange errors, and LittleCranky67 ended up realizing what had caused it all: LaLiga’s indiscriminate IP blocking. After share your frustration on HackerNewshundreds of comments confirmed other similar cases, and in them we also discovered something interesting: how to officially claim LaLiga. Or at least, how to try. A sad old story. LaLiga he shields himself in the Judgment of December 18, 2024 issued by the Commercial Court No. 6 of Barcelona. This allows you to demand from operators such as Movistar, Vodafone, Orange or Digi to block at the IP level any address that is identified as a source of illegal IPTV broadcasts during LaLiga football matches. Many of those IPs are Cloudflare shared IPs, so when the IPTV service IP is blocked, all domains associated with that shared IP are blocked, which can be hundreds or even thousands. And in those domains there are web pages of private usersfrom companies that they stop being able to sell and also critical services for developers such as Docker, GitHub or GitLab. The irony is that lockdowns don’t work. While many users complain about these blocks and how are affecting websites and services that usemany others continue to remember on social networks that in reality the blocks to view these IPTV broadcasts can be easily circumvented in many ways. The most popular, use VPN services. In LaLiga they know that this method is widely used, so for months They are also working on blocking those services. It doesn’t seem to be serving a lotand whoever really wants to watch the football game without paying has many relatively simple ways to achieve it. If you are affected, you can claim. In that thread, several users remember that one way to try to change things is for users to protest, complain and complain en masse. There are several ways to do it: Telecommunications User Service Office. It is the official body in Spain for these cases. A formal claim can be filed for arbitrary loss of service or censorship, and even claim financial losses if the blockade prevents you from working. Those who have a digital certificate or Cl@ve can do so directly online. Complain to your internet provider. It is also important to open a support ticket with your operator.

Complaint to the European Commission. It is also possible to enter the European Commission complaints website to send a claim to the entity. We explained it in Xataka and the process is another way of trying to stop this situation with the help of European bodies. The BOE serves as a defensive argument. In these complaints it is advisable to cite the BOE-A-2022-10757 as a legal reference. It corresponds to Law 11/2022, of June 28, General Telecommunications (LGTel) and is the fundamental rule that regulates your rights as an internet user in Spain. The message that we can write is the following: “Under the protection of Law 11/2022, of June 28, General Telecommunications (BOE-A-2022-10757), specifically regarding the rights of end users (Chapter IV) and the principles of continuity and quality of service, I present this claim for the blocking of access to legitimate IP addresses (specify which ones, e.g. Cloudflare/Docker) unrelated to any illicit activity. This blockade constitutes a violation of my right to communication and the contracted service, causing harm (professional/personal) by preventing the operation of work/security tools. “I request the immediate cessation of said technical restriction in compliance with the provisions of the aforementioned Law.” The nightmare continues. The debate in HackerNews is nothing more than confirmation of what internet users in Spain have been suffering for more than a year. A private organization has the power to order ISPs in a country to indiscriminately block IPs without judicial review in real time, during regular hours, causing documented harm to third parties that have nothing to do with the original violation. In that thread some users compare the situation with that of the Great Firewall of Chinanot so much in intensity as in its logic. We are faced with an infrastructure of selective censorship that seems to be able to be applied to any content that an actor with sufficient judicial power wants to block. From football to tennis or golf. In fact, things could go further, because what began as an attack against illegal broadcasts of football matches could now be seen in other sports such as tennis or golf. Telefónica —which follows in the footsteps of LaLiga— wants to extend indiscriminate blockades to the Champions League, tennis or golf. This threatens to suffer these side effects for many more days and for many more hours, and can mean that for a good part of the week, users like LittleCranky67 find themselves unable to download Docker packages or access thousands of legitimate websites that end up being knocked down by these blocks.

Without the support of Europe it would have been literally impossible.

We tend to see the space race as that. A competition in which one country comes first. In 1969 it was said that the United States defeated the Soviet Union (USSR) in the race to put humans on the Moon. Before, it had been the USSR that had prevailed by taking the first human into space. Now, many consider that NASA has once again emerged victorious, by defeating China, which He also wanted to put his flag on our satellite. But, in reality, it has not been NASA alone that has achieved this first step towards returning to lunar territory. Other agencies are involved and, above all, we cannot forget that, without the support of Europe, these four astronauts would not be traveling to the Moon. Literally. Three European engines. The Orion capsule is guided, directed and powered by a set of 33 engines called the European Service Module. The surname is not trivial, since It has been designed by the European Space Agency (ESA) and built by Airbus under ESA guidelines. In addition, the engineers at ESTEC, ESA’s technical center located in the Netherlands, work closely with their colleagues at NASA’s Johnson Space Center, monitoring that everything is working properly with this essential piece for the proper development of the Artemis missions. The main engine. The European Service Module has a main engine that is responsible for promoting the speed changes necessary to guide Orion properly towards the Moon. It is a space shuttle engine that has already traveled to space on 6 missions between 2000 and 2002. ESA scientists have reconditioned and restored it so that it fits perfectly into Orion and meets all the needs of this capsule. Eight support engines. The main engine has eight auxiliary engines that intervene in the orbital corrections that are necessary for the trip to reach a successful conclusion. 24 precise motors. Finally, the European Service Module has 24 smaller engines, distributed in 6 capsules, which are responsible for driving more precise control of Orion’s movements. They can function individually or collaboratively, as needed. A key piece at a critical moment. On the second day of Artemis II’s trip, the European Service Module starred in one of the critical moments of this trip to the Moon. This is translunar combustion by injection, a process by which the capsule is accelerated to propel itself out of Earth’s orbit and, therefore, begin the real journey to the Moon. It’s not the first time. The European Service Module was already used on Artemis I with magnificent results. At that time the capsule was sent to the Moon unmanned. Without a doubt, the participation of four astronauts in the process makes this trip even more exciting, which continues to be possible, in large part, thanks to European intervention. Therefore, although NASA has the most press in all of this, we must not forget that it was Europe that pushed its astronauts, as well as a Canadian astronaut, to the Moon. Instead of talking about careers, we can talk about teamwork and, in the process, remember that, although some space agencies make more noise than others, those that work in the shadows are as indispensable as the rest.

In the middle of 2026, a childhood without mobile phones sounds impossible. A town in Ireland is doing it

by

Greystones is a small town on the coast of Ireland, more specifically in County Wicklow. 22,000 inhabitants, semi-detached houses, coastal landscapes, a railway network which allows you to reach Dublin in just over half an hour… A priori, it is the perfect town to enjoy a peaceful life just a stone’s throw from the bustling Irish capital, where companies such as Google or Apple. However, in recent years the town has been in the news for another, very different reason: his crusade against the use of smartphones among the children. His case shows that it is still possible to live a cell phone-free childhood. What has happened? That the small town of Greystones (Ireland) has strived to teach the world a lesson: to show that in 2026 it is possible to keep children away from mobile phones, Instagram, TikTok and the rest of social networks. We just need to join forces to change the sign of social pressure. The initiative is actually not new. Greystones launched their crusade in 2023when it already aroused the curiosity of the rest of the world. However, the unknown remained as to how the experience would turn out. Now we already know. Where does the idea come from? The debate around what age Children should start using mobile phones or social networks and the influence that these have on them is not new. It’s not a concern unique to Greystones, either. There however it happened something interesting during the pandemic. When students returned to classrooms after lockdown, Rachael Harper, headteacher at St Patrick’s School, found that some children were having trouble sleeping or struggling to concentrate. She wasn’t the only one to notice. Other colleagues confirmed that they perceived similar attitudes among their primary school students. What caused them? It didn’t take long for teachers to focus on the use of cell phones. They even encountered children who controlled their calories with apps. Eoghan Cleary, a teacher at another Greystones school, also found that his students admitted seeing violent content on the Internet. The sum of all these factors led several primary schools to send a survey to around 800 parents When asked about the topic: more than half acknowledged that they noticed their children were anxious. In some cases they had even sought professional help. It was enough for the city to decide to make a move. What exactly did he do? We mentioned it before: join forces. Eight primary schools in the Greystones and Delgany area came together to launch an initiative they named ‘It Takes a Village’ (‘It takes a whole village’). Its main tool was the ‘voluntary code without smartphones’, a community pact that basically encourages residents to prohibit children from using mobile phones during their primary education period. In practice this is equivalent to keeping young people away from networks and smartphones until they turn 12 and enter secondary school. The pact is of course voluntary, free and failing to comply with it does not result in fines, but the idea is that whoever signs it applies it both at school and at home. Were you that worried about the issue? It seems so. “As principal of St. Patricks Elementary School I have observed growing concern among parents and teachers,” Harper admitted in 2023 in a column opinion published in Guardian. “The level of anxiety of children in schools has grown steadily, since easy access to online and mobile content has become a threat to childhood. We felt the need to act. The process started with a realization: childhood is becoming increasingly shorter.” Has it worked? That was three years ago. Now we finally know how the initiative is working. Recently The New York Times dedicated an extensive report in which, among other issues, it confirms that the campaign has had a more than reasonable reception. They have supported her 70% of parents and above all it has penetrated the town, moving to businesses and politicians. He has even made his mark beyond Wicklow. Shortly after it was launched ‘Smartphone Free Chilhood’a citizen movement that advocates delaying children’s access to smartphones at least up to 14 years. How has he achieved it? In 2023, Harper herself insisted in that, if it really wanted to work, the initiative had to go beyond the classrooms. “It’s not about enforcing a code. It’s about building a strong network of services that helps children, families and teachers deal with anxiety-related challenges.” The report of The New York Times suggests that goal is also being achieved at Greystones. Beyond what parents do at home, the campaign is completed with training workshops and events such as phone-free beach parties. Even with the commitment of local businesses. For example, one store has offered to help children who need to locate their parents. Is it so important? Yes. And for a simple reason. The very name of the initiative (‘It takes a whole village’) makes it clear that, to succeed, the campaign must play with collective pressure. And it seems that he is achieving it. “In networks everything is collective. Addressing it jointly is the best option,” recognize Jennifer Whitmore, member of the Irish parliament and mother in Greystones. In other words: delaying a child’s access to mobile phones and social platforms is very easy when they are surrounded by other kids of the same age who also do not use them. “What Greystones demonstrates is that parents and communities are not powerless,” agree Clearly. Is it that dangerous? Harper insist in that the initiative is not based on “anti-technology stances” nor does it want to deny children the use of smartphones. The key lies rather in rethinking the times and what it means to have a mobile phone. “Our goal is to ensure that they are adequately prepared and emotionally capable to take on the responsibility that comes with having a smartphone when accessing secondary education”, claims before citing a UNESCO report that suggests it can take up to 20 minutes for a child to concentrate … Read more
