is losing homes and gaining Airbnb apartments

by

There are many shows held around the world, but few can boast the levels of popularity of the FIFA World Cup, which will be held this summer in North America. Nor to drag so many followers. In January the organization revealed that in just 33 days it had received more than 500 million of ticket requests for the sales phase of the random draw. If FIFA’s calculations are correct, more than six million of people will attend the tournament stadiums, leaving an average of 450,000 visitors in each host city. Such an avalanche of tourists is already being noticed in the housing market of Mexico City (CDMX), one of the cities involved. What has happened? That the CDMX residential market is strongly feeling the effects of the 2026 World Cup, which will be held this summer in Canada, the United States and Mexico. At least that’s what he claims Urban Memorial Projecta citizen platform that has set out to document the effects of gentrification, tourism and real estate pressure in the Mexican capital. A few days ago the organization launched a statement in which he warns that, on the eve of the competition, CMDX is suffering a flight of homes that are leaving the residential market to be offered in the tourist market, much more profitable. What does the data say? The figures come from Inside Airbnb and they are eloquent. According to your recordsin a matter of six months (December 2024-June 2025) Airbnb gained 770 “new accommodation spaces” in the Mexican capital. “On average, three apartments or entire houses were stolen from the residential rental market every two days during the first half of 2025 to be allocated to tourists through Airbnb,” underlines Urban Memorial. The organization recalls that, according to the latest update from Inside Airbnb, at the end of June 2025 CDMX had 27.51 active accommodations. Why is it important? Because the group appreciates “an acceleration in the conversion of housing from residential use to temporary accommodation” and warns that this transfer also occurs in “a critical moment” for the capital, in the midst of a residential crisis and on the eve of the World Cup. Added to these factors is that a good part of Airbnb’s offer corresponds to complete homes (17,713), the number of which far exceeds that of private rooms (8,995). The study also warns that this is the ‘photograph’ from a few months ago. “Surely it is growing at an even faster rate as we get closer to the World Cup,” remember the platform before specifying that Airbnb’s offer is not distributed evenly throughout the metropolis. 81% are concentrated in the four most central districts with the best services, with Cuahtémoc at the head. There alone, the “undisputed epicenter of the business”, there are more than 12,500 accommodations, 46% of the entire city. Are they denouncing anything else? Yes. The platform remember that although the Tourism Law (renovated in 2023) clarifies that accommodations advertised on websites such as Airbnb cannot be rented for more than 180 nights each year, this guideline is “generally violated.” To be more precise, after studying the data from Inside Airbnb, the organization found that there were 7,532 properties (about 30% of the total) that had already exceeded the limit of available nights. Who includes the standard? Especially large owners, according to Memorial. Is it the only warning sign? No. A few months ago the newspaper Reform he wondered how the World Cup was affecting the rentals of homes and commercial premises in CDMX, Guadalajara and Monterrey, venues of the tournament. His conclusion was striking: he estimated that rents in total would become more expensive between 25 and 40%. Already in December Julio César Mendoza, manager of the Inmuebles24 platform, slid the possibility that prices would rise, especially in the venues closest to the stadiums where the matches will be played, focusing on “flexible or temporary contracts” signed for the World Cup season. Does only the World Cup influence? No. Of course, not all of the increase is solely attributable to the FIFA Cup. The Spot2.mx platform remember that at least in the specific case of CDMX, the increase in the cost of commercial spaces is already coming from behind and is related to the gentrification of certain areas of the capital. In fact, there are studies that ensure that rents in the residential market they have shot up 45% between 2020 and 2025, displacing the population to the periphery. In his case the World Cup would act more as an accelerant. The truth is that there are landlords who started months ago to remodel their commercial spaces to attract brands during the months of June and July. Some Mexican media they also talk of landlords who have stopped renewing rental contracts precisely coinciding with the proximity of the World Cup. Does it only affect houses and commercial premises? No. Although recently the hoteliers of Mexico City, Guadalajara and Monterrey they assured Since the anticipated occupancy level in its accommodation is low (30%), the sector expects demand to grow as the match dates approach. In fact, they predict that during key days occupancy will skyrocket to around 80 or 90%with rates 100, 150 or 300% higher than normal in key areas. The hotels near the stadiums hope to sell out.

Spain is letting the lisp die in Andalusia without knowing that the /θ/ sound is a global rarity that we are losing

by

In recent days, the University of Granada has presented a macroatlas with almost half a million audios that shows how the way of speaking of Andalusians has changed. The research is very interesting for many reasons, but today I want to focus on something specific: the slow, but inexorable agony of lisp. What is lisp. While the distinction between ‘s”https://www.xataka.com/”z’ and seseo gains ground in the south, lisping is losing speakers in the only place where lisping is used. It is a sociological question, yes: researchers are clear that stigma is the main force against this phonetic subsystem. But there is something else Because, in reality, what we are seeing is not just the death of the lisp, it is the end of the sound (θ) itself: one of the most unknown oddities of the Spanish language. A Spanish oddity? Although it is not something that is often explained much, the ‘c’ sound (/θ/) is relatively rare in the world — only in 43 of 566 languages ​​(7.6%) in the world. WALS sampling appears and only in 4% of the counts in typological databases (UPSID: 3.99%; PHOIBLE: ~4%). That is, very few living languages ​​have that sound among their phonetic repertoires. To give us an idea, the phoneme of the ñ (ɲ), quintessence of Spanish, appears in 35% of the world’s languages. But… what about the ‘c’? The usual explanation Why (θ)/(ð) are less frequent and why they are disappearing is simple: they are “soft” fricatives; That is, they are less strident sounds than (s)/(z) and, therefore, have less perceptual salience. This is what makes them tend to be lost or transformed easily over time. That does not mean that the Spaniard of the future is going to be sesante; but there is a high probability that it is sesante. The heritage of a language in the trash. It is clear that it cannot be argued from a philological point of view that the disappearance of (θ) is a bad thing. The Earth turns, languages ​​change. But it is striking that in a society in which historical heritage continues to be “valued”, the progressive loss of a sound does not set off alarm bells. And that it does so because we are not capable of accepting the diversity of our own language, normalizing it and defending it in the public sphere, is perhaps worse.

More and more Spaniards use AI in their daily work. They also fear losing their jobs because of it.

by

Artificial intelligence has ceased to be a technological promise and has become something that more and more Spanish workers already have installed in their daily routine. Not long ago, talking about AI at work sounded like science fiction and, on many occasions, it was even seen like a trap at work. Today, the data tells a very different story and adoption not only growsbut it does so at a speed that surprises even the analysts themselves. A report from the InfoJobs platform highlights that in the last year not only has the percentage of employees who use AI in their work grown, but increasingly understands them better. It is increasingly used at work. According to the IV InfoJobs Artificial Intelligence Report63% of professionals in Spain regularly use AI tools in 2026. This figure represents an increase compared to the 52% recorded in the 2025 report and 50% in 2024. Within this increase in the presence of AI in the workplace, the report highlights that the spontaneous use of AI stands at 51%, 17 points more than in 2025. The data indicates that the difference between the total use of AI and that declared has been reduced from 18 to 12 points. That is, workers not only use AI more, but they also better identify what technology they have in their hands and what they can do with it. They have an AI and they know how to use it. In 2025, 48% of professionals said they did not know or did not know how to use AI tools. In 2026, that percentage has fallen to 28%, a reduction of 20 points in just one year. In this sense, the generation gap becomes more visible. Among those under 35 years of age, the declared use of AI reaches 63%, compared to 47% among those over that age. Mónica Pérez, Director of Communication and Studies at InfoJobs, summarizes it like this: “Artificial intelligence has gone from being an emerging technology to being progressively integrated into normal work processes. Beyond the increase in its use, the data reflects greater identification and awareness of the use of this tool by professionals, which points to an increasingly consolidated adoption in the work environment and a paradigm shift.” ChatGPT leads, machine translation goes down. Among the most used AI tools in Spanish companies, ChatGPT-type chatbots stand out, which have gone from 37% in 2024 to 52% in 2026 and already top the ranking of the most used. The integration of AI in design tools and as a programming assistant does not go unnoticed, with a significant increase in use in the workplace, standing at 17% and 16% respectively. For its part, automatic translation, one of the main uses of AI at work in 2025, it drops from 58% to 51%. The percentage of users who claim not to use any specific tool in their work has been reduced from 7% to 4%. All this fits with what is happening globally that, by eliminating friction at work, employees tend to take on more tasks, generating more fatigue and workload if it is not managed well. Fear of dismissal grows. Having a greater understanding of the potential of AI tools and knowing what they are capable of also increases the uncertainty about your future job. 39% of those interviewed for the InfoJobs report believe that AI will cause some specific layoffsalthough without replacing specialized work, a percentage higher than 30% in 2025. 23% predict more widespread substitution, while the same percentage considers that the workforce is not easily replaceable with AI alone. This perspective varies depending on presentation of your position to AI. Among those who already use AI regularly in their workplace, 46% see the scenario of specific layoffs as likely, compared to 26% of those who do not use it. The AI ​​gap between companies. According to the study ‘Digitization of the Spanish company‘ Prepared by the UGT union with data from the INE, 21.1% of companies with more than 10 workers used AI in 2025, which represents a considerable increase compared to the previous year in which 9.55% was registered. Among large companies with more than 250 employees, the percentage rises to 58.2%, an increase of 13 points year-on-year. The data from the report indicates that Spain exceeds the OECD and EU average in AI integration, with 20.3% of companies regularly using AI. However, Spain is still very far from the implementation of this technology in Denmark (42%), Finland (38%) or Sweden (35%). Despite the general increase in the use of AI, there is data that indicates that this progress is not being transferred to internal talent since the percentage of ICT specialists in companies it has been reduced from 16.44% to 15.67%, a figure that UGT describes as “unexpected and disturbing.” In Xataka | The biggest fear was that AI would take our jobs.

Sparkling water has a “secret” to losing weight. And it has nothing to do with its nutritional properties.

by

Sparkling water is one of those ‘rare’ options on the drinks menu that few people consume in our environment, but little by little it is gaining popularity. prominence in the dietary field. All thanks to a recent scientific publication that pointed to its benefits in order to lose weight with its consumption, although there is quite a bit of fine print under this premise. The study. The epicenter of this new wave of enthusiasm is placed in a study published in BMJ Nutrition where a fascinating hypothesis is raised: carbon dioxide dissolved in water could increase the glycolysis in the organism. A process that basically does is ‘break’ the sugar we have in our cells to obtain energy. In this way, we would be reducing one of the components that gives rise to the ‘hated’ fat that we want to avoid. As? Drinking sparkling water and having this happen is not something very ‘normal’ a priori. Science suggests that, when consuming carbonated water, the CO₂ that gives rise to those bubbles that we see on its surface passes into the bloodstream, where it could stimulate our red blood cells so that they use more glucose and therefore, it does not accumulate as fat. On paper, it sounds like music to the ears of anyone looking to lose weight: drinking water to burn off sugar. There is small print. The study itself is a brief report and the scientific community she has been quick to qualify it: Even if the mechanism exists, the isolated effect is too small to produce “miraculous” weight loss just by drinking water. In this way, we are not facing a great ‘fat burner’, but rather a metabolic curiosity that will hardly be noticed on the scale if it is not accompanied by other changes. The real trick. If sparkling water doesn’t magically “burn” calories, why do many nutritionists insist that it helps with weight control? The answer lies not in metabolism, but in fluid mechanics and satiety. This is not something new, but studies from 2008 already showed that carbonated drinks had a direct impact on the stomach. The first effect focuses on the distention of the stomach, since the gas takes up volume. Thus, when drinking sparkling water, there is greater distension of the ‘upper’ part of the stomach compared to normal water. This makes we get full faster and we don’t want to continue eating. There is more. But beyond filling us up faster, this distension sends satiety signals to the brain through the vagus nerve. That is why the bubbles “trick” the stomach, making it believe that it is fuller than it really is. In this way, the brain interprets that it is full and inhibits our desire to continue eating. thanks to chemical inhibition. Japanese investigations on oral stimulation with CO₂ suggest that this feeling of fullness can reduce subsequent food intake, although the effect is modest and short-term. The substitution factor. The strongest argument for sparkling water has nothing to do with CO₂ or gastric motility, but rather behavior. This is precisely what I was aiming for. a meta-analysis by McGlynn which reviewed what happens when we replace sugary drinks with calorie-free options. The results in this case are quite clear: replacing cola or packaged juice with water (with or without carbonation) reduces weight, BMI and body fat. And this is where sparkling water shines as a replacement tool, since for many people accustomed to the sensory “aggressiveness” of a carbonated soft drink, flat water is boring. And its impact. Sparkling water offers that oral stimulation, with the beloved sting of bubbles, without the “toll” of empty calories. If carbonated water helps you quit sugary sodas, that is the relevant clinical impact, not the fact that carbonated water speeds up the burning of sugars we have previously consumed. It’s not for everyone. Although hydration guides indicate that sparkling water hydrates exactly the same as regular water, it is not for everyone. That same mechanism that helps satiety (gastric distension) is the number one enemy for certain clinical profiles, such as for those who have gastroesophageal reflux or irritable bowel syndrome. Here, increasing the pressure of the digestive system can aggravate these diseases.

an AI that follows you from one device to another without losing track

by

Motorola has presented its first ‘fold’ type foldable at Lenovo Tech World 2026, an ultra-premium line called Signature and, above all, Motorola Qira: an AI platform (they call it “personal ambient intelligence”) shared with its parent company Lenovo that works on smartphones, tablets and computers, maintaining the context between all of them. Why is it important. Lenovo and Motorola’s commitment to AI is something different: that AI is the same on all your devices. It sounds obvious, but it is not so obvious. Qira maintains the context, the data and the conversation. You start something on your mobile in the morning and continue it on your laptop in the afternoon without repeating anything. The move attacks today’s biggest productivity problem: switching between apps and devices often breaks your workflow. Each change involves explaining again what you need. Between the lines. This is clearly a response from Lenovo to the strengths of the Apple ecosystem. Apple has much of its advantage in syncing between iPhone, iPad and Mac through proprietary software, and now Lenovo is trying to replicate it with AI as the common thread. The difference is in the execution. Apple controls hardware and software. Lenovo depends on Android and Windows, third-party systems. Your only asset to create that fluid experience is for AI to be the glue. In detail. Qira is not just another chatbot. It is an “ambient intelligence” (the naming is from Motorola) integrated at the operating system level, always present without having to open an app. Summoned with “Hey Qira”, with a dedicated key or by tapping the permanent item on the screen. Works even offline using local AI. The proposal is based on three attributes: Presence: It’s there, it can proactively suggest things or wait for you to call it. Actions: Execute tasks between applications and devices without having to manage each step. Perception: Build a unified knowledge base (with your consent) that includes your interactions, memories and documents across all devices. The use cases. Lenovo and Motorola have defined specific functions where Qira should shine: “Next Step” suggests actions based on what you’re doing and helps you switch devices without losing track. “Write for me” composes emails, documents or messages directly where you work, adapting to your tone. “Catch me up” summarizes what happened while you were away and helps you get back to tasks. “Pay Attention” transcribes and translates meetings in real time, captures key points and generates summaries. privacy. Processing occurs primarily on the device to keep data local. Cloud services are optional and require explicit consent. Lenovo insists that Qira never collects data without user permission. The context. No manufacturer has yet managed to make their devices “talk to each other” naturally using AI. Samsung has tried it with Galaxy AIGoogle with Gemini and Microsoft with Copilot. Everyone stumbles upon the same thing: their assistants don’t remember what you did on another device. They are great on one device but they stop being great when we switch from one to another. The specific applications do shine there (ChatGPT, Gemini, Claude, Grok…), but they do not have the system-level integration that Qira, Galaxy AI and company do propose. Qira unifies under one name the dispersed solutions that have arrived until now: motorcycle ai (the lower case imperative is a Motorola thing), Lenovo AI NowCreator Zone and Learning Zone. The platform integrates collaborations with Microsoft 365, Copilot, Qualcomm, Intel, Perplexity and Google. Motorola does not have a large share in the premium segment, if Qira works well it could be an argument to attract customers. Qira will arrive in the first quarter of 2026 on “select” Lenovo devices and then on compatible Motorola phones. They have not yet communicated the list of models that will receive it. The approach is pragmatic: better to integrate what already works than to compete with OpenAI or Google in the creation of foundational models where they would hardly be able to scratch anything. Qira is not its own model, but a platform that connects different AI services depending on the task. Go deeper. Beyond Qira, there is a strategic reading: Lenovo is trying to become the reference manufacturer for those who do not want Apple but do not want to rely only on Google. It is a difficult space to fill. They all failed because creating ecosystems requires years of investment, gaining committed developers, and reaching users willing to change their habits. Lenovo has financial muscle and Motorola retains brand prestige. But you’ll need Qira to really work. In Xataka | The technology industry has been searching for the “next smartphone” for a decade.

Madrid and Catalonia are losing national population while gaining foreign population

by

The latest data of the INE on population flows show a curious phenomenon (almost contradictory) in two of the most populated regions of the country: Community of Madrid and Catalonia. Although both maintain their capacity to attract emigrants from other countries, they have been losing already resident populations for some time. in favor of other autonomieswhich translates into an “internal” migratory balance in the red. In short: your migratory motor has two speeds. The big question is to what extent it is the result of housing cost. What has happened? that the latest data from the INE confirm that Madrid and Catalonia remain the favorite destinations for immigrants who decide to move to Spain, but at the same time both communities see how many of their own neighbors pack their bags to move to other regions neighbors, such as Castilla-La Mancha (case of Madrid) or the Valencian Community (case of Catalonia). The data is especially interesting if we take into account that they arrive with a residential market with skyrocketing prices. Community Total immigration balance SM Exterior indoor SM Andalusia 61,912 67,770 -5,858 Aragon 18,024 17,048 976 Asturias 14,225 10,340 3,885 Balearics 17,118 15,735 1,383 Canary Islands 27,770 27,331 439 Cantabria 5,977 5,051 926 Castile and León 26,407 24,316 2,091 Castile-La Mancha 27,746 23,819 3,927 Catalonia 122,593 129,030 -6,437 Valencian Community 115,742 104,776 10,966 Estremadura 4,008 5,096 -1,088 Galicia 30,325 27,730 2,595 Community of Madrid 100,971 113,964 -12,993 Murcia region 17,531 18,704 -1,173 Navarre 6,976 7,264 -288 The Basque Country 24,190 23,420 770 Rioja 3,906 2,998 908 Ceuta 217 416 -199 Melilla 630 1,460 -830 Is the trend so clear? Yes. It comes with taking a look at the tables of INE immigration balances to verify it. If we look at the balance of foreign migration (the difference between the population from other countries that moved to Spain and the Spanish population that settled in other nations), in 2034 the Catalan community registered a clearly positive result: +129,030 people. Things change when we talk about “internal migration”, which reflects population movements between the different Spanish communities, always within the country. In that case the balance left a negative result: -6,437. That is, there were 53,585 people from other regions who settled in Catalonia, but 60,022 Catalans who packed their bags to go to other autonomies. And in Madrid? The ‘photo’ It’s not very different. Its external migration balance showed a positive result of 113,964 people, but that of “internal migration” left a negative balance, with the loss of 12,993 residents. In 2024 there were 100,342 people from other communities who registered in one of the municipalities of Madrid, but 113,335 did exactly the opposite: they decided to pack their bags and change the capital for other regions. In fact, the Community of Madrid shows the worst internal migration balance (at least in net terms) in the country. Only Catalonia (-6,437) and Andalusia, which showed a negative balance of -5,858, come close (and by far). It’s not really a surprise. In May we told you how there are people from Madrid moving to Valladolid and taking the AVE every day to continue working in the capital. Can it go further? Yes. The INE allows you to go beyond the autonomous communities and obtain data at the municipal or even submunicipal level, by neighborhood. It is an interesting tool because it confirms how this double phenomenon is exacerbated in the two main cities of the country: Madrid and Barcelona. In the first (Madrid) the external migration balance was 73,959 people and the internal one was -18,722. In Barcelona these indicators marked +46,974 and -17,020, respectively. Valencia also presents a positive external balance and a negative internal balance, despite the fact that the community as a whole gained migration. Why is it interesting? Because population flows are not isolated phenomena. They occur in a context marked by multiple factors, among which is (especially if we talk about recent years) the increase in price of housing and an increase in ‘overcrowded homes’those in which people reside in overcrowded conditions. There are also another clear trend: the increase in certain migratory flows, such as those of Venezuelan origin, a phenomenon that is being felt in neighborhoods of all types of income. A recent study from Idealista confirms that Madrid and Barcelona are two of the most expensive cities in Spain. And he is not the only one. Photohouse calculate that Madrid and Catalonia are two of the regions with the most expensive second-hand housing in Spain, only surpassed by the Balearic Islands and (in the case of Catalonia) the Canary Islands and Euskadi. Does housing have that much influence? The INE study suggests this, especially because it appreciates differences within the municipalities themselves. “In some of the main cities it is observed that the most central districts are losing population, while the most remote ones are gaining it,” comments the organizationwhich cites several specific cases already confirm the trend: “In 2024 in Madrid, the subdistricts on the southeastern periphery were the ones that had the highest balance. In Barcelona and Valencia, those in the south were the ones that gained the most.” Of course more factors come into play. The Canary Islands or Balearic Islands, two regions very marked by rising housing prices and tourism, closed 2024 with a positive balance in both external and internal migration, just like the Basque Country. Castilla-La Mancha and Castilla y León also grew, receivers of a good part of the population that decided to leave the capital, and the Valencian Community, also a destination for internal migration from Barcelona.

Movistar Plus+ was making a comeback after four years of losing customers. Telefónica has decided to cut its workforce

by

Telefónica has set 119 final departures in Movistar Plus+part of the ERE that will eliminate 4,554 positions in Spain. It is a reduction compared to the more than 200 losses initially planned, but it comes at the worst moment: when the platform was finally adding clients again. Why is it important. Movistar Plus+ has 3.75 million (the most recent data is from September 30) , the best data since 2018 after years of collapse. It lost almost 650,000 clients between 2019 and 2023, hit rock bottom, and was already beginning to recover. Now Telefónica is cutting muscle just when it needed to step on the accelerator. The paradox. The company bet a lot of money buying Canal+ and launching its own productions to compete with Netflix and Prime Video. When the numbers improve, he reduces the workforce. The inevitable question: how are you going to keep up with global giants with fewer people and a tighter budget? Yes, but. Subscriber growth does not guarantee profitability. Telefónica has reoriented Movistar Plus+ towards a more flexible and cheaper offer, unrelated to convergent packages. That adds customers but compresses margins. And competing in streaming without a global scale is very expensive. The unequal context. Netflix already has more than 300 million subscribers in the world. Prime Video exceeds 200 million. Disney+ around 120 million. Movistar Plus+ has 3.75 million in Spain, at the end of the third quarter of 2025. The difference in scale is brutal and translates directly into budget for content, technology and distribution. What works. Football continues to be the lifeline. LaLiga and the Champions League keep many subscribers hooked who, without that content, perhaps would not have stayed for so long. But a platform cannot be built only on sports rights that also increase in price every cycle, as we saw a few days ago. What deserves more luck. Movistar Plus+’s own series and documentaries have objective quality. ‘Poison‘, ‘The Messiah‘, ‘The Plague‘, ‘riot police‘, ‘The Pioneer‘ either ‘Rapa‘ demonstrate the ability to find powerful stories with local cultural sensitivity. Netflix and Prime also produce Spanish content, but Movistar Plus+ has built its own catalog that transcends obvious trends and connects with the public in another way. The problem is not the quality of the content. Quality is sometimes not enough when you compete against infinite budgets and recommendation algorithms fine-tuned with data from hundreds of millions of users. The big question. What will become of Movistar Plus+ if it continues to contract? It was beginning to regain ground, but doing so with 119 fewer people makes it difficult to maintain the pace. Without the investment capacity to match the Netflix-Amazon-Disney triumvirate, the room for maneuver narrows every quarter. The background. This ERE is not an isolated case. Telefónica has been thinning its workforce for years while it pivots towards infrastructure and gets rid of unprofitable Latin American subsidiaries. Marc Murtra, president for one year, has renovated its entire dome. The 2024 one cost 1,300 million and took 3,421 positions. This new adjustment will be more expensive and deeper. Between the lines. The unions have ended up accepting forced dismissals in minority companies such as Movistar Plus+, despite having set it as an initial red line. The pressure from the workforce to guarantee early retirements in other subsidiaries has weighed more than maintaining positions. UGT and CCOO have appealed to “common sense” and “responsibility”common euphemisms to justify a capitulation.

‘Avatar 3’ is going to be a movie so disproportionately expensive that it runs the risk of destroying and losing money

by

‘Avatar: Fire and Ash’ is already, as has happened with all previous installments of the franchise, one of the most anticipated films of the year. Each new installment breaks box office records, and yet James Cameron’s statements are more pessimistic each year about the continuity of the series. Are you sure that ‘Avatar’ is as good a deal as it seems? We snooped into his finances. The paradox. ‘Avatar: Fire and Ashes’ arrives wrapped in an economic paradox: its production budget exceeds 400 million dollarsa figure that places it among the most expensive films ever filmed. And yet, its own director is not clear if the business is worth it. Cameron has been unusually frank about his franchise’s finances and he put the question bluntly: “Will we make money on Avatar 3? Surely some. But the real question is what kind of profit margin there will be, if any, and whether that will be enough of an incentive to continue in this universe.” The wild mathematics of break-even. The arithmetic of ‘Fire and Ashes’ defies standard Hollywood logic. With 400 million in production expenses and a marketing budget that analysts place between 100 and 175 million, it would need to exceed $1 billion at the box office simply to break even or break evenaccording to the more or less assumed industry rule that a film must gross 2.5 times its production budget to be profitable. The case of ‘The sense of water’. The previous installment of ‘Avatar’ gives us some previous lessons on the subject. The sequel cost more than $1 billion in total costs: $400 million in production, another $400 in global marketing, $300 million in shares for Cameron and producer Jon Landau, plus cast salaries, residuals and general expenses. Cameron was not exaggerating when declared that ‘Avatar 2’ was “the worst business case in the history of cinema” and that it needed to become “the third or fourth highest-grossing film of all time” simply to not lose money. The film fulfilled that apocalyptic objective: raised 2,320 million and finally generated 531.7 million net profit. But that deceptively solid figure hides a crucial detail: The studios do not receive all the money from the box office. Movie theaters take approximately 50% of US domestic revenue, 40% from international markets, and up to 75% in China. That is, of those 2.32 billion, Disney actually received just over 1 billion. The rest stayed at the box office. The crisis of inflated budgets. ‘Avatar’ is one of the most visible symptoms of a disease that affects all of Hollywood. The industry has a systemic problem of out-of-control budgets, which affects such well-known films as ‘Star Wars: The Rise of Skywalker‘ ($490 million), ‘Jurassic World: Dominion’ (584 million) or ‘Mission: Impossible – Deadly Sentence: Part One’ (400 million). A analysis of the causes It leads us to multiple factors that explain this phenomenon: inflation has increased the value of the dollar by 15% since 2020, making all aspects of production more expensive. But in addition, streaming platforms altered the economy of stars, accustoming them to higher initial charges, demands that they later transfer to traditional productions. And there is also a visual effects arms race: franchises like superheroes try to surpass each other in spectacularity, and infect the rest of the blockbusters. For this reason they are films that “might not make money even with objectively decent box offices.” The unique case of ‘Avatar’. James Cameron invests in developing pioneering technology that then benefits the entire industry: the underwater motion capture that Cameron and Weta FX took a year and a half to perfect for ‘The Sense of Water’, now reduce costs for the sequels being already invented. But the budget escalation is relentless: ‘Avatar’ cost between 237-280 million, ‘Avatar 2’ between 350-460 million and ‘Avatar 3’ exceeds 400 million. The franchise is a guarantee of box office success, but the profit margins are worryingly narrow. In Xataka | Cameron’s ‘Titanic’ was going to be a flop.

BYD CEO is clear about why the company is losing steam in China

by

Wang Chuanfu, president and CEO of BYD, has publicly acknowledged for the first time the reason behind the company’s sales decline in the Chinese market. During an extraordinary shareholders meeting held on December 5 in Shenzhen, the CEO bluntly admitted that the manufacturer has lost the technological advantage that differentiated it from the competition. According to local media, Wang said that they had lost that ‘wow factor’ in the domestic market, in reference to the impact that their innovations previously generated. The underlying problem. The local media China Securities Journal collected the statements of the head of BYD, who stated that the drop responds to two main factors. On the one hand, he admits that BYD’s technological advantage is no longer as pronounced as in previous years, which has reduced the surprise effect of its products in the market. On the other hand, the CEO acknowledged that unresolved practical problems persist, such as the slow charging speed of its vehicles in low temperature environments, a critical aspect for users in certain regions of China. The numbers confirm the trend. In November 2025, BYD sold 480,186 new energy vehiclesthe highest monthly figure of the year, but which represented a decrease of 5.25% compared to the same month in 2024. It is the third consecutive month of year-on-year decline. Domestic sales were particularly weak, at 348,300 units, a drop of 26.81% year-on-year. In contrast, exports exceeded 100,000 units per month for the first time, reaching 131,700an increase of 297% that has become the company’s main growth engine. We have already seen how they have broken into Europe. For BYD and the rest of the Chinese manufacturers, it is important to continue consolidating their foreign business for two main reasons: to continue feeding their factories and to increase their profit margins in the face of a China that seems to live in a constant price war. The competition tightens. Chinese manufacturers such as Geely, Changan and Chery They have intensified their offensive with efficient hybrid and more affordable electric models, eroding their market share. Furthermore, the homogenization of products in the industry has made it difficult for BYD to stand out like before. In September 2025, SAIC Motor even temporarily surpassed BYD in monthly sales, according to they counted from CarNewsChina. BYD’s response. Wang Chuanfu hinted that the company is preparing “heavy technologies” that will be announced soon, although it did not offer details. The CEO stressed that BYD’s strength lies in its team of approximately 120,000 engineers, who will be key to regaining technological leadership. The company plans to intensify its investment in electrification and smart technologies over the next two to three years. Self-criticism included. Wang also made an exercise in self-criticism by admitting that favorable market conditions in previous years generated a certain complacency in the areas of marketing and merchandising, as they point out from CnEVPost. And now what. BYD revised its global sales target for 2025 downward, from 5.5 million vehicles to approximately 4.6 million. Between January and November, the company accumulated 4,182 million units soldwhich represents 90.9% of the adjusted objective and a growth of 11.3% year-on-year. Figures that contrast with the spectacular expansion rates of previous years: 218% in 2021, 209% in 2022, 62% in 2023 and 41% in 2024. Stella Li, its vice president, already warned us during the Xataka Awards gala We will soon have very interesting news from the manufacturer. So we can only wait to see what the firm’s strategy will be to alleviate the effect of competition.

We are discovering how the brain “hacks” us to make us hungry. And it is a key step in the race towards losing weight.

by

Right now, treatments to lose weight are the order of the day, with a clear protagonist like Ozempic. The problem is that beyond the aesthetic effects that are achieved, there are many doubts about both the side effects as well as all the effects it has on the body. But little by little science you understand much better how they achieve their effectwhich seems like a real miracle for many. What we knew. In general, these treatments They are ‘copies’ of GLP-1 which is a hormone that we produce normally in our body and makes us have the feeling of satiety. The moment we increase it exogenously we have a greater feeling of satiety that allows patients to lose weight (although with a risk of bouncing when treatment is stopped). But beyond this effect, the action it could have directly on the brain was something that had only been explored in animals. Now, a new study published in Nature has crossed this frontier thanks to Casey Halpern’s team, which has taken advantage of a “unique opportunity” to observe, for the first time in humans, the impact of Mounjaro (tirzepatide) directly into the reward center of the brain. Why it is important. The discovery of how the brain can ‘hack’ our body to eat much less opens many doors for us in the field of pharmacology to be able to continue working on definitive treatment. against obesitybecause we are seeing that it is something in high demand by many people who find it necessary to have this help (although it is not a miracle) to be able to reduce their weight. And we even see how in the United States purchasing is becoming more and more accessible. And we say that it is a miracle, because Ozempic or Mounjaro does part of the work, but we must not leave aside the change in eating habits to adjust the diet and be able to maintain it after stopping the treatment. The problem is that there are people who after stopping the treatment continue eating normally, and logically they see that there was no miracle involved. How it was done. The study focused on a 60-year-old woman with treatment-resistant obesity and type 2 diabetes. This patient was already taking Mounjaro for diabetes, and coincidentally, she was participating in another trial to treat dysregulated eating. This coincidence allowed the researchers to do something unprecedented: use the electrodes, already implanted in its nucleus accumbens (NAc)for hear brain activity while the drug took effect. And this brain nucleus is really important as it is the center of pleasure in humans and reward, that is, it is the point that can be modulated to restrict food consumption. The sign of craving. Those cravings we have for eating a little chocolate, a greasy pizza or a hamburger are something we all have because it is what gives us pleasure. In this case it was seen that the signal changed over the months, specifically the delta-theta frequency band. In the first months of treatments with Mounjaro, the patient had no desire for food in that sense of craving. Something that corresponded to a null signal in this nucleus, so it could be said that the medication was silencing this ‘noise’ that is generated in the pleasure center. The problem is that in the fifth to seventh months, despite being on the maximum dose of medication, the patient again had severe concern about food. And here again the signal in the nucleus had spiked to match that of those people who had no treatment. An advantage for the future. The most important finding here is that the change in the brain preceded the behavior. That is, before having a relapse this signal was increasing as if it were a warning signal. That is, a future where a sensor can detect this brain signature and alert the patient or doctor that the effectiveness of the drug is decreasing, before that the person will feel the cravings again in an uncontrolled way. Much ahead. This is a study with a single person, and it has many limitations and its conclusions logically cannot condition the clinical activity of the use of these medications. What it is useful for (and a lot) is to understand that the brain has a lot to do with this weight loss as if it were a real button to control eating habits. Perhaps silencing this brain nucleus in a very specific and sustained way may be the ‘holy grail’ that weight loss science seeks to control these cravings that can ruin a diet imposed by specialists. Although there is still a lot to investigate and it is only a first door for other medications that can complement Ozempic or Mounjaro, which has given great results.
