problem

The European Bizum wants to be working next Christmas, but first a problem must be resolved. One of power sharing

by

“Wow, but if it gives me the option to pay with Bizum, how cool.” That was my expression a few months ago when in an online purchase the online store offered me to pay directly like this. No debit or credit card, no Google Pay. With a Bizum. The instant payment system that is triumphing in Spain is so good that What we want is for it to work further. And that is precisely what the banking entities of the European Union want, who saw a “European Bizum” as a great idea. There’s just one problem. Who will control it. The European Bizum is approaching The European Central Bank he has been fighting for five years for that application that does the same as Bizum but throughout Europe. There was a major power struggle here with two large factions. On the one hand, the consortium Spain-Italy-Portugal. On the other, that of France-Germany-Belgium-Holland, who wanted to impose its own Bizum, called Wero. Fortunately, in recent months we have seen how the positions of both consortiums have become closer and the unification now seems almost definitive. This is what they indicate in five dayswhere they quote “market sources” who talk about the agreement being signed in early 2026. The European Bizum should start operating at the end of next year if everything goes as expected. This system may not be a new application, as requested by the French and German entities, but rather a system that interconnects existing ones. It is a somewhat more confusing solution but also more practical, because users will not have to change apps. For example, a Spanish user will be able to send a Bizum to a German at no cost, and the German will receive that money in his Wero app in a way that is transparent to him. The European banks participating in the negotiations have reached an agreement to establish a new company that will be the owner of this interconnection technology. There was talk of applying certain commissions, “but it was finally rejected in favor of a multilateral network.” Power distribution And there is the new challenge: Who is in charge in this new society? The distribution of power is now the great unknown, and there are several options. On the one hand, each national platform receives practically the same participation. On the other hand, the distribution should be made based on the volume of each country and then corrected. The Bizum model seems like it can also be applied to that pan-European solution. It is interesting to realize that as explained in the economic newspaper, the owners of Bizum are 22 Spanish banks, among which the participation varies: Caixabank: 25% Santander: 21% BBVA: 18% Sabadell: 12% Other minority banks such as Unicaja, Bankinter or Cajamar have lower participations, but Bizum’s statutes establish that no bank can have more than 25% participation. Do we need a digital euro? Europe has been looking for a solution for some time that would allow it to mitigate its dependence on the two great giants of electronic payments: Visa and Mastercard. The European Payments Initiativecreated in 2020 by 16 banking entities, had precisely the objective of creating a European interbank network that competed with these platforms and with others such as PayPal. And little by little it has been proven that Bizum was precisely a great candidate to achieve this. The application, with more than 30 million users in Spain, has not stopped growing in benefits and alliances like the one a year ago they signed with Revolut. There are still other obstacles in the creation of this European Bizum. For example, building a common deposit guarantee fund to deal with large US entities. It does not seem that this is going to be a major impediment to the implementation of the pan-European alternative, and that makes us wonder what happens now with the digital euro. The European Central Bank (ECB) has been designing the design of this digital asset for years. There have also been important movements in that sense, and if the European regulations are approved in 2026, there will be a pilot starting in 2027. The EU seems to want to be ready for a possible first broadcast in 2029. However, that European Bizum will theoretically solve part of what the digital euro wants to achieve, so does it make sense? It is very likelyespecially since the digital euro is a legal tender issued by the ECB. It is not just a way to transfer money, but a digital form of official money itself. Both alternatives can coexist, and this European Bizum may be the best way to promote the use of the digital euro.

You feel like going to Sri Lanka because you saw it on Instagram. The problem is that the person who recommended it to you was an AI

by

The image is familiar. A young woman smiles from a beach with turquoise waters. In the following publication, he appears walking along a cobblestone street in Marrakech. Below, he poses at a luxury hotel in the Maldives. The skin is perfect, the body responds to the prevailing canons and the text accompanies with inspirational phrases about traveling, discovering cultures and “living in the moment.” Nothing seems out of place. Until you discover the reality. That traveler has not flown, she has not walked those streets or tried the food she recommends. It doesn’t exist. She is an influencer generated by artificial intelligence and is part of a phenomenon that is growing quietly: the normalization of artificial profiles that influence the real decisions of millions of people. A silent, but massive boom. In the last two years, Instagram and other social networks have been filled with virtual influencers: characters created with generative AI who pretend to be real people and publish travel content, lifestyle or fashion, the best known case in Spain is Aitana Lopez. Some indicate it more or less clearly in their biography; others do so ambiguously or almost invisibly. However, what is interesting here is how the examples multiply in the tourism sector. Sena Z has been presented as “the first travel and hospitality influencer created with AI”, It’s a collaboration between the luxury group Cenizaro Hotels & Resorts and the technology firm Bracai. Sena publishes cultural recommendations, messages about sustainability and photographs from exotic destinations. Another notable case is Emma, ​​the official influencer and chatbot of the German National Tourism Office. Emma not only publish content on Instagrambut answers questions in more than 20 languages ​​from the official website of the organization. As explained from the entity to the Washington Postits creation is part of a strategy to “stay at the forefront of digital innovation.” Other profiles are added to these profiles, such as Radhika, Emily Pellegrinior corporate avatars like Samathe Qatar Airways virtual stewardess who appears both on the airline’s website and on social networks, publishing as if she were living real experiences. These are not isolated experiments. As detailed by The New York Timesairlines, tourist offices and brands are increasingly turning to these avatars because they are cheaper, faster and completely controllable. An AI influencer does not get sick, does not get tired, does not age and does not generate personal controversies. Inexperienced influencers. The question is inevitable: what happens when the experience is not real? Just look through these profiles to see it: they recommend destinations, restaurants and cultures that they have not experienced. Even so, they generate engagementaccumulate thousands of likes and comments, and influence travel decisions. From the brands’ point of view, the appeal is evident. According to data collected by the New York mediacreating an advanced avatar can cost between $5,000 and $15,000, compared to traditional campaigns that easily exceed six figures. In addition, content can be produced without travel, without filming equipment and without negotiating with human talent. However, for real creators, the impact is already being felt. Human influencers cited by the same medium explain that brands are reducing payments, eliminating extras and offering less advantageous collaborations. AI thus becomes a new direct competition within the creative economy, a sector valued at more than 200 billion dollars globally. Is someone regulating it? While Technology advances quickly, regulation tries to catch up. Going home, in Europe, the clearest answer comes through the Artificial Intelligence Regulations (AI Act). Article 50, which will come into force in August 2026establishes transparency obligations for providers and users of AI systems. Among them: Report when a person interacts with an AI system. Mark content generated or manipulated by AI (text, image, audio or video) in detectable format. Force deepfakes and AI-generated texts that report on matters of public interest to be declared, unless there is human editorial review. The European Commission has already started the preparation of a Code of Good Practices for the marking and labeling of content generated by AI, with the participation of experts, platforms and civil society. The goal is to facilitate compliance before the law is fully applicable. However, many virtual profiles do not clearly indicate either their artificial nature or their commercial links, leaving the user in a field of ambiguity. Unreal bodies, algorithmic authority. Beyond destination promotion, most AI influencers share common traits: eternal youth, slim bodies, perfect skin and a total absence of imperfections. This phenomenon coincides with the return of Y2K aesthetics and extreme thinness on social networks, a trend that has been linked to a decline in body diversity. The most notable case was due to advertising campaigns with models generated by AI, like Guess in Vogue. Mental health experts warned that constant exposure to unreal bodies can aggravate self-esteem problems and increase risk of eating disorders. The difference, they point out, is key: while traditional retouching started from a real body, AI creates bodies that have never existedimpossible to achieve even in theory. This logic has been taken to the extreme with phenomena such as the Miss IA pageantwhere artificially generated models compete showing bodies without pores, without age and without history. According to plastic surgeonsmore and more patients come to consultation with images created by AI asking for impossible interventions and pointing out the risk of frustration, obsession and psychological damage. The underlying problem: we no longer know what is real. All of this occurs in a broader context: a crisis of visual confidence. As my colleague in Xataka has analyzedthe massive generation of hyperrealistic images has broken a chain that for centuries seemed solid: if something was seen, it had probably existed. Today, that presumption has disappeared. Seeing is no longer equivalent to knowing. In this new scenario, we not only doubt whether an influencer has really traveled, but also whether the image itself corresponds to something that happened. The consequence is a permanent suspicion that affects memory, attention and the way we relate to digital reality. The technical solution—seals, metadata, … Read more

The big problem with putting solar panels on crops is shade. The University of Jaén has found a solution

by

In search of fulfilling the decarbonization goalswe are filling the field with solar panels. Giants like China can do it combining other activities well, but in the case of smaller countries, things change. Spain is an examplewith a field irrigated by crops that is also being plagued by panels. Now, a research team from the University of Jaén has found the key to continue deploying solar panels without interfering with crops. A panel with minimal shading that does not compromise its energy generation. The agrovoltaics. Different reports have pointed out how the temperature will increase by 1.5 to 3.2 degrees If we continue the same as until now. For this reason, the European Union marked the milestone of 30% of its energy comes from renewables by 2030 to, in 2050, achieve climate neutrality. Wind is important, but what almost all countries are embracing is photovoltaics. The price of the plates has fallen to the ground thanks to the China overproduction and it has begun to be deployed massively. The problem is what we mentioned: it takes up a lot of space, which opens a direct conflict with the farmland. There, agrovoltaics is becoming established as a solution to place panels that do not interfere with the cycle of some crops, and mixes with beekeeping and the livestock. But if we want to continue expanding photovoltaics, panels that provide less shade are needed. Panels and photosynthesis. That is where the solution devised by the University of Jaén comes into play. In a study Published in Science Direct, researchers detail a technology that allows a panel to efficiently generate electricity, while allowing crops to receive enough light to perform their optimal photosynthesis cycle. To do this, the team has taken into account two technical parameters: the average visible transmittance and the average photosynthetic transmittance. In practice, they indicate the amount of light useful to the plants that reaches them after passing through the panel, and they point out that different studies estimate that, for most crops, the minimum value should be around 60%. In that spectrum, plants produce normally. Status of the “transparent” panels“The photovoltaic industry has been working on this for some time. There are two approaches: Non-wavelength selective panels: They are those that absorb a large part of the solar spectrum and achieve transparency by reducing the color of the material or leaving gaps between the cells. With them, transparency is not adequate. Wavelength Selective Panels: They are those that absorb, above all, ultraviolet and near-infrared radiation, but allow a large part of the visible light to pass through. It is what the plants need and, in this case, the transparency of the panels is greater and more suitable for crops. RearCPVbif. In the two groups the industry is testing very different technologies, from polycrystalline silicon to organic cells and color-sensitized panels, but the Spanish team’s approach is somewhat different. The semi-transparent photovoltaic modules They are the STPVs, but what is proposed by the University of Jaén is a system called RearCPVbif, or “Bifacial Rear Concentrator Photovoltaic.” Unlike conventional semi-transparent designs, this technology concentrates and redirects reflected light towards the back of the bifacial cells, generating an increase in electrical production without reducing optical transparency, which is what allows light to reach the plants. It is an STPV, but with rear optical concentrators. In statements to PV-MagazineÁlvaro Varela-Albacete, co-author of the research, points out that STPV technology is being underused and that, with these rear concentrators, there is “a substantial increase” in energy generation without compromising optical transparency. “And how much is the transparency factor? 60%, according to the study, so it would be suitable for most horticultural crops. Next steps. In the study they also mention that they have taken into account that a crucial aspect for agricultural viability is thermal behavior, indicating that, in their tests, the cell temperature was below 70 degrees. This is important so that the panels do not create a “greenhouse” that affects crop patterns. And most importantly: this technology has already attracted attention. Numerous promising studies are published throughout the year, but their application is not always clear. In the case of this ReadCPVbif technology, the co-author of the study, Eduardo Fernández, points out that they are already engaging in conversations with different organizations to accelerate the development of the technology. Now, the route hour includes an evaluation of the benefits for crop growth, with different test campaigns on real crops. In any case, it aims to be a particularly relevant technology in the intensive horticulture that occurs in regions of Spain such as Almería, where apart from the sea of ​​plastic, also the photovoltaic sea is rising. If the two things can be combined, it would be a great step for both sectors. Images | University of Jaen, Σ64 In Xataka | Almería has been Europe’s great “sea of ​​plastic” for years. Now it wants to be another sea: that of solar panels

We’ve been telling ourselves for 100 years that breakfast is the “most important meal of the day.” The problem is that it is not true

by

They’ve been hammering us with that slogan for so long that it should be true. That is, if from different speakers they proclaim that under no circumstances should we skip breakfast, it will be because it is lunch. most important of the day. But how we already pointed herethe studies on which they have relied to affirm this are conclusive. It also does not seem true that it is good to have breakfast to “start the day with energy”, nor that it reduces our appetite throughout the day. So who and why started proclaiming it? The history of breakfast is like many other social uses, something that has more to do with the roots of the context from which it came than with an innate need of our body to practice it. Several things came together between the 19th and 20th centuries so that breakfast became established as just another meal in Western societies. The first, the change of production model. Before, workers, mostly rural and dedicated to work in the fields, ate breakfast quickly whatever was out therelike last night’s leftovers. It wasn’t so much a meal as it was an appetizer. With the arrival of cities and the industrial revolution, work schedules were established. The workers, who spent the entire day working, saw the benefit of eating something before going to work. From 1822 onwards And here things started to get interesting. Progressively, the more money American workers were able to earn, they ate more meat. It was the star product to eat in the morning. They could prepare a meatloaf, a chicken or beef dish in the same way they would at lunch or dinner time. And all of this cooked with butter. The dyspepsia or indigestion became a public health problem on the level that obesity is now. The people of North America ate poorly, foods that were too heavy and altered their intestinal flow. People who needed to eat very well to go to work. The 19th century was also the time when western doctors They began to worry about nutritional health, germs and, later, vitamins. Thus, while the newspapers and magazines harshly criticized the problems caused by dyspepsiathe industry and the market naturally looked for a substitute. There came muesli and cereals, then minimally processed flour or corn that in many cases had to be soaked before consumption. The initial flavor and appearance of the cereals was that of military porridgebut they were attractive to a large part of the consumers: it seemed like a “health” productnot like those red meats that prevented good circulation. Furthermore, it was a food that I didn’t need to be preparedas easy as putting them together with a little milk so you can swallow them and go to work. Replacing big meals in the morning with a light product The health of the population improved, which is why many doctors and cereal merchants used this slogan to expand their consumption: breakfast is the most important meal of the dayand that is why you should take care of yourself early in the morning. Is practically the same idea of ​​health that whole grain houses continue to sell us so that we can lose weight. Corn flakes arrive Breakfast then began to be seen as the solution to all the problems. For the little ones, without a good breakfast they would not be able to reach their maximum level of effort at school. Also alcoholism It was caused by lack of food in the morning. According to certain prestigious doctors of the period, morning hunger encouraged the employee to begin to abuse the bottle until he became dependent on it. Some vendors went even further and talked about how their cereals They could cure malaria and appendicitis. Already then the cereal was promoted as “organic” foodAs we see today, some products are sold more expensive and not necessarily with better nutritional results. But the beneficial halo of the cereal remained and extended to the breakfast ritual, whether it was processed wheat, fruits or other foods. breakfast had come to stay. From the 19th and 20th centuries we move to the 21st century, when the saying, never sufficiently proven by science, has already been established as an immovable truth. Cereals have long been no longer tasteless porridge but small ones processed sugar balls in boxes with smiling animals that bill billions of dollars a year. And there is another agent that, for years, has been interested in making sure you remember that “breakfast is the most important meal of the day” and, therefore, eat quite well: fast food chains. Some essays have pointed out how the marketing of companies like McDonalds or Starbucks is being much more aggressive in morning products such as McMuffins or cheesecakes than in foods at lunch or dinner time. According to them, the new big dispute is here. While many workers have already decided on their meal locations, there is an increase in people who is going to breakfast at chains outside the house. And how mornings are the time for routinehumans tend to choose one place or another to have our breakfast and not leave the pattern except in case of emergency. If McDonalds gets you to go to their establishment in the morning, in a way you are marrying them gastronomically. And, well, you know, it’s the first meal, so it’s okay if it’s a little excessive, you’ll burn it off throughout the day (this, as we already explained, it is not completely contrasted). Thus, from a creditable beginning in which citizens’ nutrition was improved, we have moved to a point where the industry has been adapting to our tastes and modifying our diet to the point of harming us all. Although, if we think about it, the phrase is still as true now as it was 300 years ago: “breakfast is the most important meal of the day.” It is the most important. And the most discussed.

The “my cat is fat” problem is so common that the industry has come up with an idea: “Ozempic for cats”

by

In just a few years, drugs such as Ozempic, Wegovy or Mounjaro have gone from being discreet treatments for diabetes to become a great social phenomenon. His promise—lose weight through a simple weekly injection—has opened a new chapter in human medicine. Now, this pharmacological revolution is beginning to expand beyond people: cats could be the next to receive an adapted version of these treatments. Goodbye fat cats. Okava Pharmaceuticals, a San Francisco company dedicated to chronic diseases in companion animals, has started a pioneering clinical trial called MEOW-1whose objective is to evaluate the safety and effectiveness of OKV-119, a subdermal implant capable of releasing exenatide—a GLP-1 agonist—sustained for months in overweight or obese cats. The intervention aims to simplify a treatment that, in humans, usually requires weekly injections. Here, everything comes down to a single gesture. “You insert the capsule under the skin, and six months later you come back, and the cat has lost weight. It’s like magic,” says Chen Gilor, the veterinarian responsible for the study. speaking to the New York Times. A pioneering study. Okava’s interests did not arise out of nowhere. Prior to MEOW-1, the company evaluated prototypes of the implant in two preliminary studies. A work published in Frontiers in Veterinary Science demonstrated that the OKV-119 implant could be easily implanted and removed, that it was well tolerated, and that its plasma levels of exenatide correlated with weight reduction in healthy cats for more than one month. Subsequently, research published in BMC Veterinary Research delved into this line: they implanted five cats with the designed prototype for 84 days, what they observed is that during that period stable levels of exenatide were maintained and four of them reduced at least 5% of their body weight, along with a lower caloric intake. These results motivated the move to a trial in real obese cats, which Okava plans to run this summer. According to the companyMEOW-1 will be the first formal feline weight loss study based on GLP-1 agonists. How does the implant work? OKV-119 uses the NanoPortal platformdeveloped by Vivani Medical. According to scientific studiesthis technology uses: a titanium reservoir, a membrane with nanotubes that regulate the passage of the drug, and a system designed to ensure a constant and prolonged release without pronounced peaks. Furthermore, this type of administration allows us to overcome the main difficulty associated with GLP-1 in veterinary medicine: lack of adherence. Studies indicate that giving repeated injections to a cat is complex, stressful and can drastically reduce the continuity of treatment, ithe same as what happens in people with injectable drugs. The implant seeks to solve that problem with an approach one-and-done: a subdermal insertion in a veterinary office, without daily intervention by the caregiver. According to The New York Timesthere are veterinarians who already use human GLP-1 agonists off-label in diabetic cats, but its cost and need for frequent administration limit its use. Hence the relevance of a device that could keep the medication active for half a year. But only in cats? Although MEOW-1 focuses exclusively on felines, Okava and Vivani have confirmed an expansion of the project to dogs, another species with obesity rates greater than 50% in the United States. The company states that its goal is to reproduce in dogs the metabolic effects observed in cats: improved insulin sensitivity, reduction in fat mass and greater energy efficiency. With the expectation that these changes may even promote healthier aging. With both markets, the commercial potential is evident. According to estimates collected in Xatakathe global human obesity drug sector could exceed $100 billion by 2030. Veterinary medicine would be a new frontier. Feline obesity is a global epidemic. The interest in an “Ozempic for cats” is not a whim. It is an answer to a growing problem. A review published in Journal of Feline Medicine and Surgery places the prevalence of feline overweight between 40% and 63%, although it continues to increase. When you ask veterinariansthe same patterns almost always appear: cats that live exclusively indoors, very little movement, food available all day, too many treats, sterilization and a very common problem: many owners are not aware that their cat is gaining weight. The consequences are not minor: insulin resistance, diabetes, joint problems, urinary diseases, anesthetic complications and liver disorders, in addition to a reduction in life expectancy. And the latest evidence goes even further. A proteomic analysis that evaluated 288 proteins in cats with obesity found important changes in inflammatory processes, in the complement system, in coagulation pathways and in lipid metabolism. In other words, feline obesity affects the entire organism, it is not just a “fat cat.” Many open questions. Although MEOW-1 is moving forward with positive expectations, mass adoption of an “Ozempic for cats” is far from a fact. The first unknown is the price. In humans, GLP-1 cost several hundred euros a month, and it is not clear whether a semi-annual release veterinary implant will really be affordable for the majority of caregivers. Cost could become the main barrier to entry, especially considering that feline obesity is a common problem, but not always perceived as a health priority. The second uncertainty has to do with the available scientific evidence. So far, studies on OKV-119 have been preliminary and with extremely small samples (between 5 and 15 cats). They work, yes, but we still don’t know what will happen on a large scale, or how animals with diseases or in varied home environments will respond. Finally, there is the question of scientific independence. For now, all published studies on OKV-119 come from teams linked to Okava or Vivani, the companies developing the implant. There is no independent, large-scale evidence, and this matches a pattern already observed in human GLP-1where much of the initial research is driven by the industry itself. A new era in feline medicine? The questions surrounding this new milestone in the treatment of feline obesity are piling up: will these preliminary results be enough to justify regulatory approval? Will caregivers change … Read more

Huawei is building its own alternative ecosystem to CUDA. If it succeeds, NVIDIA will have a serious problem

by

When talking about NVIDIA, almost all the focus is on the hardware: the H100Blackwell, racksenergy consumption, nanometers… It is understandable, but it is a mistake. The defensive moat – the moat– NVIDIA is not the hardware. Is CUDA. CUDA is not an add-on to the chip, it is the de facto standard upon which most of the AI ​​code on the planet is written, optimized and debugged. Changing GPUs without changing CUDA does not exist. And switching from CUDA means rewriting years of work. That is why it is a moat. Why is it important. Huawei’s big bet is not to “make a Chinese H100.” It is to build a path for the developer to reach Ascend without feeling like you are changing planets. The restrictions are accelerating it. Exports have split the world in two: An ecosystem that revolves around NVIDIA. And another that China is trying to lift against the clock. In that second, Huawei is not just playing chips: is playing “ecosystem”in AI and outside of it. And therein lies the nuance: you can be years behind in chips and still reduce dependency if you get the software to swallow. In detail. Huawei is attacking the problem on three fronts, with a pragmatically Chinese logic: not to replace everything at once, but to open shortcuts. Native stack (CANN + MindSpore). It is your “pure” alternative: your own environment and your own tools to get the most out of Ascend. The cost today is high, there are complaints of instability, the documentation is rather messy, and the community is much smaller. PyTorch support. This is the most strategic move. Huawei does not try to make the world love its framework– Try to ensure that the world doesn’t have to leave PyTorch. torch_npu acts as an adapter to run PyTorch models on Ascend, but with one problem: it is not native and suffers with every PyTorch change. If PyTorch advances and your backend lags behind, the developer notices. Portability via ONNX. Here Huawei looks for its best window: inference and deployment, not training. ONNX works as a bridge format: you train where you can (often NVIDIA) and deploy to Ascend. It’s a less romantic and more useful approach: if shortages hit, moving inference to local hardware is an immediate relief. Between the lines. The real story is that Huawei is trying to replicate the “trick” that made NVIDIA great: turning its hardware into an experience. That’s why the tactic that explains everything appears: putting engineers in the client’s home to migrate code and optimize it. It is not scalable as a business model, but it is scalable as a transition model: you buy time while you mature tools, libraries and support. And there is another derivative: if China gets enough teams to adopt Ascend out of necessity, over time that can become habit and then infrastructure. Not because it is better, but because it is already integrated. Yes, but. Huawei has two limits that cannot be fixed with marketing: Hardware improvement rate: Roadmap analysis suggests relative stagnation and a gap that could widen, not close, if NVIDIA continues to accelerate cycles. Off-chip bottlenecks: memory (HBM), tools and industrial capacity. You can add “worse” chips, but you need to make a lot of them and build a lot of systems. And now what. If this movie continues, we will see two clear signs: Less hype of chips and more real migration stories: how many computers have moved to Ascendwith what frictions, with what performance losses. Less obsession with training in Ascend and more normalization of the hybrid pattern: I train where I can, I deploy where I must. NVIDIA will continue to be CUDA. Huawei is not “a chip.” It is an escape strategy. And the restrictions are the fuel that is making it inevitable. In Xataka | With HarmonyOS NEXT Huawei has achieved something incredible.

La Niña is going to be meteorologically “less intense” than we expected. And that actually hides a problem.

by

There is a 55% chance that the world will cross the La Niña thresholds in the coming weeks. And although The World Meteorological Organization insists that it will probably be a weak and brief episode, that does not mean that it will not cause us problems. Many problems, in fact. First because it is going to catch us with a changed pace. When world meteorological agencies indicate that La Niña will be low in intensity, what they are also doing (often inadvertently) is telling authorities that it won’t be that bad. And that is technically true, but socially speaking it is a mistake. WMO A global event… Let us remember that, with the exception of the seasons, ENSO (of which La Niña is a phase) constitutes the most important source of annual climate variability from all over the planet. It is true that the cold phase usually has less impact than the warm one, but the teleconnections of The Girl They are still huge and so is their impact. …with an impact worthy of its size. In fact, under “normal conditions”, with a 55% chance of it arriving this quarter, many countries would be preparing for its consequences. Above all, because, under “normal conditions”, there are many: For example, in the southeast of the American continent temperatures become warmer than normal. Likewise, they get colder in the Northeast. Less rainfall than normal is expected in Ecuador and Peru, and torrential rains are expected in Northeast Brazil. In Mexico, it is common for La Niña to cause (or make more intense) drought in the north and center of the country, while increasing torrential rainfall in the Pacific, the southern Gulf of Mexico and the Yucatan Peninsula. In Spain, for its part, it is usually synonymous with less rain. In other words, bad news. But we are not in “normal conditions.” As I say, the WMO messages they are precise; but they act as confusing signals: the administrations are not preparing. And that, whether we want it or not, can turn even the most lukewarm of Las Niñas into thousands of problems on a regional scale. But we must also take into account the global scenario. Because, as the WMO also points outLa Niña may bring slight global cooling. However, this should not motivate a reduction in efforts against climate change: the accumulated warming is so great that temperatures will most likely remain above average. That is, climate change is still underway. And, unlike other years, not even La Niña can do anything to contain it.

Silver is right now the most sought after and most expensive metal on the planet. And the problem is that there is not enough

by

Silver just surpassed $60 per ounce for the first time, and the impact is especially noticeable in the technology sector. The metal is essential for solar panels, electric cars, electronics and AI data centers, and demand has skyrocketed much faster than the mining industry can respond. In a matter of months, what seemed like a one-time rally has revealed a deeper problem: the world is entering a phase of real silver shortage. A record that marks a turning point. The escalation became historic this week. While this report is being written, silver is around $62.67 per ouncedoubling its value since January after five consecutive years of supply deficit. Although the rise is not surprising who follows this marketwhat impacts is its speed: according to Bloombergsilver is the best performing metal of the year, doubling its price and even surpassing gold in what is already its biggest increase in decades. But beyond the price, what is relevant is not how much silver has become more expensive, but why. The market structure has changed. Money doesn’t stop going up. For analysts and companies, this new peak has profound implications. Silver no longer behaves as a simple safe haven asset, it is a critical industrial input whose shortage can slow down entire sectors of the global economy. Unlike goldwhose function is mainly financial—, the silver it is a metal that supports electrification and the energy transition. However, the problem is amplified by the nature of the market which is narrow, volatile and without global strategic reserves. As Bloomberg recallsthere is no equivalent to gold central banks that act as a stabilizer of last resort. When physical money is lacking, there is simply no safety net. Source: TradingView A perfect storm. The rise of silver is not understood by a single factor, but by the convergence of industrial, monetary and geopolitical forces. First of all, according to Financial Timesthe silver market has been in deficit for five years, with inventories at minimum levels and production unable to respond. Silver is mostly obtained as a byproduct of zinc, copper or lead mining, making it difficult to increase supply quickly. Furthermore, the three largest producers—Mexico, Peru and China— face environmental and regulatory restrictions which further reduce production capacity. The Silver Institute foresees industrial demand increasing at least until 2030, driven by solar expansion, transportation electrification and the growth of digital infrastructure. Additionally, the global data center boom also adds to this pressure, because some of them operate with solar energy. Added to all this is a worrying dynamic: the United States has accumulated large reserves of silver due to the risk of new tariffs under Section 232. This diversion of metal to American deposits has drained inventories in London and Asia, generating a silver squeeze which skyrocketed metal borrowing costs. As pointed out in FTthe North American retail investor—for whom silver is “the poor man’s gold”—is also entering aggressively, fueling the bullish momentum. China enters the scene. The decisive factor comes from Beijing. The Ministry of Commerce of China announced in an official statement new strict conditions for exports of silver, tungsten and antimony during 2026–2027, including strengthened requirements, documentary controls and more rigorous supervision for state-owned companies that want to export metal. Likewise, the official text confirms China’s intention to protect its strategic resources for internal use, especially in sectors considered critical for its future competitiveness: renewable energy and artificial intelligence. The reason it’s clear: China wants to guarantee enough physical silver to power its own AI data centers, the expansion of which requires huge volumes of solar panels. With global mining production limited to 813 million ounces annually and new projects that take years to come online, Chinese controls could exacerbate an already structural shortage. China, the largest global refiner of silver and a central player in the solar chain, has real capacity to alter the global balance of the market. India and Russia complete the geopolitical map. On the one hand, India has become one of the great drivers of the physical silver market, with about 80% of global demand for bars and coins. According to ReutersIndian demand for jewelry and bullion has been so strong in 2025 that it has caused physical shortages and premiums on international prices during holidays such as Diwali. Added to this pressure is a new regulatory framework: India’s silver imports soared to $2.72 billion in October, partly due to measures that facilitate the monetization of physical silver, allowing consumers to convert their holdings into financial instruments. On the other hand, Russia decided at the end of 2024 start buying silver for its State Reserve Fund, a move that has contributed to skyrocketing prices against gold even further. It’s not just silver: a global reconfiguration of metals. The rise in silver coincides with a historic movement in gold. The golden metal exceeded $4,200 due to pressure from central banks, which already have more value in gold than in US Treasury bonds. A structural turn in the international monetary system. For their part, platinum and palladium have also become more expensive. This phenomenon indicates that strategic and safe haven metals are regaining a central role in the global economy. What to expect from now on. The forecasts for the coming months coincide in a common diagnosis: structural tension will not disappear, even if phases of technical correction appear. On a technical level, several analysts see room for further increases. According to FXStreetconsiders an advance towards 63.8–65 dollars plausible, supported by a weak dollar and the continuity of the buying impulse. However, since the TradersUnion portal introduce caution, the market is clearly overbought, and losing the $61.5 support could trigger short-term profit taking. Added to all this are two new forces compared to past cycles: the rise of AI, which multiplies solar demand, and China’s industrial policy, which can further restrict global supply. In this context, as analyst David Morgan warnsprecious metals are entering “a monetary inflection point,” driven by both the energy transition and loss of confidence in … Read more

AVLO’s departure from Madrid-Barcelona seemed like another problem for Renfe. He has left us an unexpected winner

by

August 2025. The summer had started out average for Renfe and ended even worse. After an exchange of information, Renfe accepted that some Talgo AVRIL trains had suffered cracks in their structures and that they were being taken out of circulation, with the consequent suspension of service. And, of course, that has had consequences for travelers. Goodbye AVLO, goodbye. Everything ended up precipitating in the last days of August but the origin must be sought a few days before. At the end of July, Renfe paralyzed by surprise the sale of tickets for the AVLO service. The news was given from The Economist: AVLO trains had suffered cracks in their cars on the Madrid-Barcelona line. A few days later, Renfe confirmed this fact and began to apply a temporary solution. The idea is that the trains would continue running but reducing traffic speed there where it was believed that the trains had cracked. Some leaked photos Already in August they demonstrated the seriousness of the events. Renfe decided withdraw AVRIL trains of the service. And days later he ended up suspending the AVLOs. September. It was a strange month for Renfe. The company maintained the AVLO service in the early stages, but in the absence of finding a solution, it ended up canceling. relocate passengers of the service low cost of the company on the AVE. That is, a kind of upgrade to travelers who already had their ticket for beyond September 8. That put the company in trouble. Or at least that was the first reading. Since then Renfe does not compete directly against Ouigo and Iryo. Without a cheaper service, the Spanish company was left without the possibility of competing directly against foreign companies. However, it does not appear to have directly affected their results. How has it affected Renfe? If we take into account the latest data from the CNMCwhich refer to the months of July, August and September, we could say nothing or very little. Renfe Viajeros (which adds data from AVLO and AVE) has increased its occupancy by 4%, the number of travelers has increased by 0.6% and they have increased the use of rolling stock by 1.6%. Regarding prices, Renfe has also won. And the company has managed to increase the number of travelers despite an obvious increase in ticket prices. The AVE cost 70.58 euros on average, 13.3% more than in the same period last year and AVLO went to 51.35 euros, repeating the same growth. Retail. But what interests us most about this period is how prices behaved when AVLO was not available. In the month of September, AVLO prices dropped but let’s remember that they were only available for very few days. Instead, Renfe only offered AVE tickets. And they were shot. In September, service prices premium increased to 75.11 euros. It is 11.4% more than the previous month. But above all, it is a price 17.4% higher than that of the same month in 2024 when there were four companies available on the market. Beyond Renfe. Curiously, the one who performed the most in this case has not been Renfe. Iryo is the company that has increased prices the most in this period. With an average ticket price of 63.82 euros, the company seemed to have positioned itself between Ouigo and Renfe, offering an alternative halfway between both services. However, the absence of AVLO in the month of September must have triggered the demand for Ouigo and Iryo. This is the only way to explain why the Italian company raised the prices of its routes to 74.13 euros in that month, just one euro less than the AVE. Year-on-year growth that month reached 83.5%. For its part, Ouigo also raised prices but remained on a somewhat more contained line. In the quarter, the average ticket price was 51.86 euros, which already represents a growth of 20% compared to the previous year. In September, however, prices remained at 52.20 euros, slightly below the month of August but, yes, 30% more expensive than in September 2024. The complete photograph. Expanding on everything that happened, as expected, AVLO’s departure from the Madrid-Barcelona corridor has only increased prices. It is something that we were already beginning to suspect and that was logical if we take into account that it is the corridor with the highest occupation and use of the line. In fact, the latter exceeds 84% ​​and remains around 10% above any other high-speed corridor with liberalized services. It is the perfect environment for passengers dynamic prices suffer.

There are dozens of influencers obsessed with helping us choose the perfect can of tuna. The problem is that what they say doesn’t make much sense.

by

There is a fine line that connects volcanic eruptions, oil combustion, and waste incineration with our kitchens: mercury. A mercury that is produced in dozens of activities (mostly human), which ends up deposited in the waters, transformed into methylmercury by millions of microorganisms, stored in fish and, finally, in our stomach. It was only a matter of time before it became the huge food scandal it is today. Methylmercury also reaches social networks. The problem is so big that there is no shortage of experts and influencers that defend messages such as choosing cans of “tuna” over cans of “light tuna.” The music is that of institutions such as the European Food Safety Authority (EFSA) that recommends avoiding large fish; The lyrics hide many problems. At the end of the day, the viral message mixes correct intuitions, with more than debatable scientific evidence (it uses, to begin with, commercial classifications that do not have direct Spanish correspondence). This is not the first time that an idea that sounds good ends up giving us headaches. And why is that a problem? Because, like it or not, fish is a centerpiece of many diets. Not only for its protein contribution, but as a priority source of certain fats that are very difficult to replace by any other means (e.g. omega-3). The thing is, with all that, comes methylmercury. And exposure to methylmercury is a tricky thing: it can harm brain development and be toxic to the nervous system. In fact, it can cause symptoms such as tremors, memory loss, and cognitive dysfunctions. The most vulnerable groups are pregnant women, nursing mothers, babies and young children. Do all fish have the same amount of mercury? No, it doesn’t. According to the Spanish Agency for Food Safety and Nutritionthere are four really dangerous species: the swordfish or emperor, the bluefin tuna (Thunnus thynnus), the shark (dogfish, mako shark, dogfish, dogfish and blue shark) and pike. These are problematic in women who are pregnant or planning to be pregnant, nursing mothers and children under 10 years of age. In fact, AESAN recommends directly avoid its consumption. The rest of the species are not problematic for the effects of mercury: they are safe and healthy. And the AESAN recommends between three and four servings a week even in the at-risk population. And aren’t there more differences according to levels? That is, are there only dangerous and non-dangerous species? No no. It is true that each species contains a different amount of mercury. In fact, each copy has different levels. That’s where the problem comes from: we need simple ‘rules’ to help us deal with uncertainty. On a practical level, according to the available studies, we can only define species with low mercury content as those on this list: Pollock, Anchovy, Herring, Cod, Bacaladilla, Cockle, Mackerel, Squid, Shrimp, Crab, Cane, Coquina, Carp, Squid, Clam, Choco/Cuttlefish, Lobster, Coquina, Sea bream, Sprat, Prawn, Horse mackerel, Lobster, Prawn, European sole, Dab, Sea bass, Mussel, Merlan, Hake, Razor clam, Oyster, Pomfret, Flounder, Squid, Octopus, Shrimp, Atlantic salmon, Pacific salmon, Sardine, Sardinella, Sardinopa, Plaice, and Trout. Everything else has medium levels and making distinctions between them is impossible on a practical level. So it doesn’t make sense to follow these types of recommendations? In general, any attention we pay to food is good. The system is configured in such a way that, if we let ourselves goour diet gets worse. However, we know that Obsessing over diet is also full of problems.. Using heuristics that complicate the purchase without substantial improvements is not as good an idea as it seems.
