its latest update brings it closer to Adobe and even Notion

by

Canva has built its success on being the non-intimidating tool. Easy, cheap and accessible to anyone. With its new update, ‘Canva IA 2.0’, it points in another direction: it adds connectors with Slack, Gmail, Notion or Google Drive; background automations and persistent brand memory. It no longer competes only with Figma or Adobe. Now it even competes with Notion, ClickUp, Microsoft and Google. Why is it important. 250 million monthly users guarantee that the formula has worked. The question is whether adding all this complexity (conversational design, agent orchestration, scheduled tasks…) makes it more powerful or simply more similar to what already exists. canva It seeks to grow and the risk is breaking the balance that has brought it here. Yes, but. All this comes from a press release. The numbers on their own models (up to 30 times cheaper and 7 times faster than the competition, they say) are published by Canva itself. Real access starts today for the first million users. Until there is real-world testing, the headlines deserve some skepticism. In detail. The main news: Conversational design: create from text or voice, without a starting template. Smart orchestration– AI coordinates internal tools to generate entire campaigns from one briefing. Active memory– Learn the team’s style and brand identity and apply it alone. Connectors: Slack, Gmail, Google Drive, Notion, Zoom, HubSpot and Google Calendar. Scheduled tasks: automations that run in the background without intervention. CanvaCode 2.0: Interactive experiences with import of HTML generated by other AIs. AI Spreadsheets: structured tables generated from natural language. Between the lines. The most interesting thing is not technical but strategic: Canva has strengthened its collaboration with Anthropic to integrate its design engine into Claude, and allows importing outputs of Claude either ChatGPT as editable elements within Canva. They clearly want to be at all the points where an idea is born, not just where it is given shape. The other reading. For years, Canva has been edging into Figma’s territory in professional collaborative design. But the connectors and automations in this ad take them away from that path: this is more like Notion or ClickUp than a design tool. It’s not entirely clear whether that’s an evolution or a loss of focus. Time will tell. What’s coming. The experimental version is available today for the first million users who enter from the home page, with progressive rollout in the coming weeks.

Universal quantum computers promise to change the world. Now they are closer thanks to giant super atoms

by

The prototypes of quantum computers currently manufactured by IBM, Honeywell or Google, among other companies, are engineering prodigies. However, they have defectswhich currently greatly limits the range of applications in which it is possible to use them. The most important of all of them is that they make mistakes and they are still not able to correct them effectively. Scientists are working on developing advanced error correction systems, and if they achieve their goal, universal quantum computers capable of dealing with a wide range of problems will arrive. The Achilles heel of current quantum machines is the extreme fragility of their qubits. And they are very sensitive to disturbances from the environment. Their interaction with the space around them can cause quantum information to be lost or altered, preventing them from delivering a correct result. This phenomenon is known as quantum decoherence and it has the ability to degrade the quantum states that need to be protected in order to carry out operations with qubits. Currently, researchers are making an enormous effort to design effective strategies for isolating qubits from the environment. However, efforts are also being made to develop less fragile qubits, and therefore less sensitive to noise. This is the plan that several scientists at Chalmers University of Technology in Sweden are working on. And they have developed a completely new quantum system designed to protect quantum information and minimize interference from the environment. Its purpose is, neither more nor less, to pave the way for universal quantum computers or large scale. Less decoherence leads to more robust and higher quality quantum computers Quantum computing experts maintain that quantum computers that will have the ability to correct their own errors can be used to design exotic materials, and probably also to develop new drugs and in industrial optimization problems, among other tasks. These are some of the applications that the qubits implemented with giant superatoms proposed by the Chalmers University of Technology team led by applied quantum physics professor Anton Frisk Kockum could put in our hands. Giant Superatoms explore two ideas long known to quantum physicists: giant atoms and superatoms. Giant Super Atoms explores two ideas long known to quantum physicists: giant atoms and superatoms. Unlike isolated atoms, a giant atom in this context is an artificial qubit designed to interact with its environment using light or sound waves at multiple physically separated points. This peculiarity allows them to protect quantum states more effectively than conventional systems, reduce decoherence and remember past interactions. The problem with using giant atoms in quantum computers is that they have significant limitations when trying to entangle them. Entanglement is essential in quantum computing because it allows multiple qubits to share a single quantum state and act as a coordinated system. To solve this limitation, the Chalmers researchers have combined giant atoms and superatoms. A superatom is made up of several natural atoms that share the same quantum state and behave collectively as a single larger atom. Lei Du, one of Chalmers’ researchers, explains to us what is a giant super atom: “We can observe it as multiple giant atoms working together as a single entity, allowing them to exhibit a non-local interaction between light and matter. This allows quantum information from multiple qubits stored and controlled as a unit and without the need for increasingly complex surrounding circuits.” For the moment, giant superatoms are a theoretical proposal, but Professor Anton Frisk Kockum and his team are going to try to build a quantum system using them. If they succeed, they could have found a new type of qubit that is much more robust, and, therefore, suitable for use in the development of universal quantum computers.

The new Galaxy A debut with discounts of up to 345 euros and financing for up to 24 months without interest

by

The new ones Galaxy A57 and Galaxy A37 They are now available in stores. Normally, buying a mobile phone or any output device means doing so at its RRP or at a price very close to it. However, in recent times we are seeing very interesting launch promotions, the kind that come in handy to get us something brand new with very good conditions. For example, you can take a Galaxy A37 256GB with a discount of up to 245 euros or a Galaxy A57 512GB with which you can save up to 395 euros thanks to Delivery and Premiere. The price could vary. We earn commission from these links And be careful, because if that doesn’t seem enough to you, you can also finance for 24 months without interest. We tell you more about this promo. The Galaxy A57 is Samsung’s best mid-range He Galaxy A57 has come to be the spearhead of Samsung’s mid-range. Curiously, It is the one with the most discounts so that we can get it. This device starts, with the launch promo, at a price of 529 euros for its cheapest version, which has 128 GB of storage and 8 GB of RAM. Below, so that you can see it more clearly, we leave you the prices that the three versions have right now: Galaxy A57 (8+128GB): 529 euros. Galaxy A57 (8+256GB): 559 euros. Its RRP is 589 euros. Galaxy A57 (12+512GB): 679 euros. Its RRP is 769 euros. With the prices on the table, let’s see the discounts that we can apply using the model with 512 GB of storage as an example: Since its RRP is 769 euros, we will already be saving 90 euros right from the start. If we use Delivery and Premierethe renewal service that the Samsung store has, we will get a direct discount of 50 euros. This is independent of the refund that we will receive for our old mobile phone, which may be up to 155 euros. If we use PayPal or Bizum as a payment method, we will obtain another additional discount of 50 euros. In addition, we also have the code ‘SAMSUNG5’ available, with which we will receive 5% discount. Adding all this together, the result we get is that we can get the Galaxy A57 with more memory for 550 euros (or 22.92 euros per month if we finance for 24 months with PayPal). A great price to which, we repeat, we can add the refund we receive for the mobile phone we deliver. The price could vary. We earn commission from these links The Galaxy A37, from 360 euros Now it’s time to talk about the Galaxy A37, a more economical option than the previous one. In this case, we are dealing with a mobile phone that has two configurationsboth with 8 GB of RAM and different storage. The launch prices from which both start are as follows: We are going to place the discounts below, which vary a little from those of the Galaxy A57: If we choose the version with more memory, we will already be saving 45 euros from the beginning. With Delivery and Release, we will receive a direct discount of 25 euros. Furthermore, the maximum refund that we can receive for our old mobile phone is 150 euros. Using PayPal or Bizum to pay, 25 euros discount. In addition, we can also use the code ‘SAMSUNG5’ to receive a 5% discount. With all of the above, the price will remain more than attractive. 403 euros or 16.79 euros per month if we finance for 24 months. All without forgetting the valuation of the device that we deliver, which in this case may be up to 150 euros that we will receive in the form of a refund. The price could vary.

Mercadona is growing more than ever and still has the capacity to grow more. The game is played in the north

by

He who leads always leads, even if he does not always lead the same way. It sounds like a tacky tongue twister, I know; but that phrase sums up well the place that Mercadona occupies in the national distribution sector. We have been repeating for years that the Valencian chain is the one that takes largest portion of the “pie” of the sector, with a business quota 27% at the state level, but that reality is not equally forceful throughout Spain. For example, in Levante its footprint skyrockets to almost 34% while in the northwest it remains at 18.2%, only three points above its most direct competitor in that region, Eroski. What does that mean? That there is a part of Spain in which the company has ample room for growth. And in a way the Duero marks it. The general photo. Whether or not you are satisfied with your commercial offer or corporate strategythere is something that cannot be denied: Mercadona has known how to play its cards well. The company led by Juan Roig has managed to gain a share in its sector that is close to 30%. And that the distribution is not un simple business in Spain, where the super regional and ultra low-cost. NielsenIQ estimates that by the end of 2025 that footprint was 29.5%0.3% more than in 2024. Worldpanel by Numerator lowers it slightly until it is in 27%. In any case, the reading is the same: the Valencian company clearly dominates, comfortably ahead of its most direct competitors, Carrefour and Lidl. It has even made a more than respectable place for itself in the portuguese marketwhere it has carved out a 7% distribution share in just a decade. Paying attention to the map. The above will surprise few. What is striking is that just revealed Expansion based on data from Worldpanel by Numerator: Mercadona may be the sector leader in value share, but that dominance is not equally solid throughout Spain. Its great fiefdom is in what the consultancy calls ‘Levante’, an area made up of the Valencian Community, Murcia and Albacete. There its share reaches 33.6%. Not only is it the highest percentage in the entire Spanish geography and it is seven percentage points above the chain’s national share. It also doubles the mark of its main competitor, Consum, which remains at 16.8%. The ‘photo’ It is completed by Carrefour, with 7.9% of the pie, Lidl (5.2%) and Family Cash (2.9%). Are there more cases? Of course. The other region in which Mercadona has gained the largest share in value is the Canary Islands, with 31.9%, ten points above the next chain on the list, Dinosol (21.1%). In the ‘South’ territory (Andalusia and Badajoz) the firm’s footprint also exceeds 30% (31.5%). The results of Mercadona are equally strong in the ‘Central’ region (Madrid, Cáceres and part of Castilla-La Mancha, Castilla y León and Aragón), where it reaches 27.5%, and ‘Northwest’ (Catalonia and the rest of Aragón), with 26.2%. In all cases the same photograph is repeated, replicated in the areas of Madrid and Barcelona: Mercadona far surpasses its main territorial rival. The northern redoubt. The really interesting thing is, however, in the northern Atlantic and Cantabrian seas. The Worldpanel data by Numerator They show that Mercadona is still a leader there, but in a much less emphatic way. First because its quota is much lower than that held in Levante or the Canary Islands. Second, because it does not maintain much of an advantage over its competitors. The most revealing case is the ‘North-Central’ (Cantabria, Navarra, Palencia, Burgos, La Rioja and the Basque Country), a territory in which Mercadona’s footprint is 19.1%. It is enough to be dominant, but it is only one percentage point behind Eroski (18.1%). In third place is Carrefour (9.8%). It is a scenario similar to what we find in Galicia, Asturias and León, what the consultancy calls ‘Northwest’. Mercadona registers its lowest share in that region, 18.22%. Second place is once again occupied by Eroski (15.1%), followed by Gadisa (10.1%), Carrefour (6.8%) and Alimerka (5.8%). Click on the image to go to the tweet. Why is it important? Beyond the fact that these percentages help us better understand how the company is distributed and how it has managed to dominate the market at a national level, the regional results from Worldpanel by Numerator leave an interesting reading about Mercadona: its future largely passes through the north of the peninsula, where it has greater room for growth. When we decide where to make the purchase, we not only evaluate the prices and variety of the assortment, we also take into account factors such as proximity or more subjective values ​​such as taste or loyalty to a brand. Together they form a ‘barrier’ that determines how far a company’s share can go. At the moment Mercadona has managed to extend its footprint nationwide to 27%. It is not unreasonable to think that even has not hit the ceilingbut the fact that in the northwest area it is only 18.2% and in the Cantabrian Sea it is around 19% suggests that in those territories the margin for growth is much broader and clearer. Not everything is advantages. No, of course. The data published by Expansion They also reveal that the leadership of the Valencian chain is much weaker in the northwest and the area made up of the Basque Country, Navarra, La Rioja and the north of Castilla y León, where it is only one point ahead of its regional rival, Eroski. This makes it easier for them to be overtaken and to see their position threatened. After all, Mercadona has not been established throughout the country for the same amount of time. In Vigo, without going any further, I only had two stores in mid-2013. And that is a city of almost 300,000 inhabitants, the largest in the entire northwest of the peninsula. If it wants to establish itself, Roig’s company will have to erode the share of … Read more

What did Nietzsche mean by “we contradict an opinion when in reality what we find unpleasant is the tone”

by

I’m not sure how to write this so as not to be unpleasant, but Nietzsche was right. Yeah, he had a weird mustachehe was loaded with opium and loved to take long walks in the Alps; but he was right. At least when it comes to one of his most apparently innocuous, but most radical ideas: that it often doesn’t matter if someone is right or wrong, that we make the decision to agree with them beforehand, that what matters most to us is the tone, the forms. The rest, although it doesn’t hurt to admit it, doesn’t matter. 150 years after Nietzsche, cognitive science has proven him right. What did Nietzsche mean…? In 1878, in the midst of a break with Wagner and Schopenhauer, Friedrich Nietzsche published ‘Human, too human‘. It was his first book of aphorisms and in it he abandons romantic aesthetics and sets out to find a new way of observing the world. In that book, the Austrian philosopher makes a complete x-ray of the psychological junk of human beings. “Opinions are born from passions,” he says in aphorism 637. “Convictions are more dangerous enemies of the truth than lies,” he writes in 483. But the one that interests us is 303. Where Nietzsche discovered confirmation bias. “Often, we contradict an opinion when in reality what we find unpleasant is only the tone in which it was expressed,” says that aphorism. And that sounds a lot like what modern cognitive science calls ‘confirmation bias‘: the tendency to search for, interpret and remember information in such a way that pre-existing beliefs, expectations or hypotheses are reinforced. First we form an idea from the tone of the person speaking to us and then we justify it. Simple, clean and perfectly confirmed by the evidence. Ultimately, what Nietzsche did is anticipate many of the ideas that Kahneman and Tversky They earned him the Nobel Prize. But that matters little, what matters is what we can learn. And, under that sullen and savage reputation, Nietzsche has a lot of useful ideas. This intuition, without going any further, has a direct and everyday application: when someone addresses us with a tone that we perceive as aggressive, condescending or arrogant, our brain activates defense mechanisms that prevent us from rationally processing the content. We do not evaluate what they tell us, we evaluate how they tell us. Reactanceconfirmation bias and post-hoc rationalization: the perfect combo to act automatically without paying attention to reasons or consequences. In the same way, Nietzschenian reflection helps us think about how we address others. And that is worth it.

that in addition to cars, Ford and Cadillac manufacture missiles

by

In 1942, the Willow Run Factory in Michigan, operated by Ford Motor Company, managed to assemble a B-24 bomber every 63 minutes, something unthinkable for an industry that until recently produced cars in series. That feat turned a civilian assembly line on a capable machine to sustain a war on a global scale. Now the drums of war are beating again in car factories around the planet. An economy that returns to war mode. The United States is beginning to recover an industrial logic that seemed buried since the mid-20th century: converting its civilian muscle into a direct extension of the military effort. He had exclusive the wall street journal that there are already Pentagon conversations with giants such as Ford Motor Company and General Motors that reflect more than just an increase in production, pointing to a transformation of the role of the industry in a context where conflicts in Ukraine and Iran are draining arsenals at an unexpected rate. The underlying idea is simple but powerful, and already we had seen in Germany in recent months: if wars consume faster than the traditional military industry can replenish, the board must be expanded and civilian manufacturers brought back. From cars to missiles. The Pentagon is not only looking for specific contracts, but the ability to redirect factories, engineers and logistics chains towards the production of ammunition, anti-drone systems or tactical vehicles. This movement implies that companies used to manufacturing cars or heavy machinery can become direct support of the war effort, something that breaks with decades of specialization in a handful of defense contractors. In practice, it is a recognition that modern warfare (especially that based on drones and high-consumption ammunition) requires industrial volumes that are more reminiscent of a war economy than the limited conflicts of recent decades. The precedent. The historical reference is inevitable: during World War II, the Detroit automobile factories stopped producing cars to make bombersaircraft engines and large-scale military vehicles. That total conversion transformed American industry in a war machine capable of supporting multiple fronts simultaneously. Today, although the context is different, the logic underlying current conversations is the same: take advantage of the scale, efficiency and flexibility of civilian industry to cover military needs that exceed the capacity of the specialized sector. Korea, Vietnam and the law that made it possible. After the Second World War, Washington did not completely abandon this capacity for industrial mobilization, but rather institutionalized it with the Defense Production Law 1950, a legal framework that allows the government to prioritize and direct production toward military needs. During the Korean War, companies such as Ford Motor Company created specific divisions for defense contracts, while General Motors and other companies adapted their lines to manufacture military vehicles, engines and supplies. This model was activated again in later conflicts such as Vietnam, although in a more partial way, consolidating a tool that allows the civil industry to be reactivated in moments of strategic pressure without reaching the total mobilization of the 1940s. A system that falls short. The background of this turn is an uncomfortable reality that could already be find in Iran: the US defense industrial base, as designed today, it’s not enough to sustain prolonged, high-intensity wars while supplying allies. The massive transfer of weapons to Ukraine since 2022 and the additional wear and tear derived from the conflict with Iran have highlighted this limitation. For this reason, the Pentagon proposes expand production beyond the usual contractors, directly asking large manufacturers what capacity they can contribute and what obstacles they encounter in integrating into that effort. The return to a logic of total war. If you like, without explicitly declaring it, Washington is recovering an idea that seemed typical of another era: that, at certain moments, the entire economy can become part of the front. From that perspective, it is not yet a total conversion as in the Second World War, but it is a change of mentality that brings civil industry to military effort much more directly. In that sense, current wars are not only redefining the battlefield, but also the role of factories, which are once again placed at the center of strategy as if history were slowly turning backwards. First it was Volkswagen in Germanyand now it’s your turn to Cadillac in the United States.

A streamer shared out-of-print movies. Now Enrique Cerezo wants him to go to prison for two years and pay 870,000 euros

by

In October 2021, five riot police equipped with shields, tactical shotguns and a battering ram burst into the home of a YouTuber from Burgos known as “El Feo”. They were not looking for weapons, drugs or criminals who had committed blood crimes, but hard drives with movies. Films out of circulation, that no one offered almost anywhere on the Internet and whose exploitation rights remained in legal limbo until that moment. David against Goliath. With that assault, the judicial process begins, which culminated on April 9 with the trial in Burgos against El Feo, the nickname of the person responsible for the YouTube channel. The Cursed and the now closed Zoowoman website. The private prosecution, headed by EGEDA (the entity for managing the rights of audiovisual producers that Enrique Cerezo has chaired since 1998), requests two and a half years in prison and compensation that the parties estimate between 850,000 and 870,000 euros. No profit motive. Zoowoman was a platform without advertising, subscription or any type of business model. Its purpose was to rescue and make available to the public out-of-print audiovisual works, films whose production companies had disappeared or that had erratic or zero commercial distribution. Zoowoman functioned as a collective repository of links: the community’s own users shared access to films hosted on external servers such as MEGA or archive.org, without the files residing on the web. Sister website. La Filmoteca Maldita, the associated YouTube channel that is currently still active, functions as an archive of essays that provide historical context and cultural readings of genre and cult cinema. It includes nearly 4,000 film analyzes (according to data provided by El Feo’s defense), which is pertinent when approaching its intentions as a cultural disseminator, rather than as a mere exploiter. Several of these videos, as well as the often unfindable films that resided in Zoowoman, have been used as teaching material in universities such as UNAM, the University of Buenos Aires or the University of Medellín, as Feo himself states in a video where he explains his case. The legal argument. The prosecution cannot claim direct profit from El Feo because Zoowoman did not generate income, so it relies on the reform of the Penal Code of 2015which expanded the definition of piracy to include “indirect economic benefit.” Under this interpretation, offering free movies can be considered a “hook” to attract followers to the main channel and reinforce the reputation of the creator and generate income through other means, which would constitute criminally relevant profit even if there is no money involved. The police investigation estimated the alleged indirect profit obtained in this way at around 12,000 euros. The defendant defended himself by explaining that this amount is equivalent to his total income as streamer during its first four years of activity, and that the messages that the agents interpreted as codes from a piracy network were donations from its community (“for your birthday”, “so that you can have a drink”), consistent with the crowdfunding model of any independent creator. In January 2025, before the trial was to take place, the prosecution tried to reach an agreement: if he pleaded guilty and paid 100,000 euros, the sentence would be reduced to one year in prison. El Feo rejected him. Who sues? Enrique Cerezo, apart from presiding over the plaintiff entity, is the owner of Video Mercury Films, the distributor that controls between 70 and 80% of all Spanish cinema, with a catalog of more than 7,000 titles. He is also the president of Atlético de Madrid and the promoter of FlixOléthe platform streaming launched in 2020 with the intention of disseminating Spanish cinema from all eras, much of it out of print or not seen for decades. The complaint that ended the 2021 raid occurred shortly after the launch of FlixOlé, whose catalog largely coincided with that distributed by Zoowoman. The logic, described by the accused himself, is that Zoowoman offered for free what the new platform charged in a subscription. Cerezo has not made public statements about the case. EGEDA acts as a private prosecutor on behalf of the producers whose rights it manages, which includes films in the Video Mercury catalogue. This is not the first time that EGEDA has embarked on complaints of this type: in 2017 it denounced WebTV device distributors and in 2022, to 17 websites that they spread content without permissionamong which was Zoowoman. Beyond the trial. If the thesis of indirect profit prospers, any free cultural dissemination channel that builds an audience could potentially be prosecuted under the same legal umbrella. There are international precedents that point in the same direction. In the United States, the case of Hachette against Internet Archive, resolved in 2024 with a defeat of the digital archive, demonstrated that courts tend to prioritize the rights of the owner over arguments of cultural access, even when the model is non-profit. The legal question. Spain has a regime for orphan works (transposed from a European directive in 2014 and developed by Royal Decree in 2016) but its use is reserved exclusively for public cultural institutions such as museums, libraries or film libraries. An individual or an independent digital creator cannot rely on it, which leaves precisely the type of initiative that Zoowoman represents without legal coverage and which is called into question from the very moment Cerezo creates FlixOlé so that these films are no longer inaccessible.

They have put the 21 most popular AI chatbots to perform differential diagnosis. They fail more than a fair shotgun

by

‘House‘It’s a series that I love. I don’t care about the intrastories in the slightest, but the process of differential diagnosis – despite all the movie stuff – drives me crazy. This ability to rule out diseases that could explain the same symptoms to arrive at the most probable diagnosis seems like witchcraft to me. Well: they have put the 21 Most Popular AI Chatbots to make that differential diagnosis and the result is clear. It fails more than a fairground shotgun. In short. He Mass General Brigham It is not an ‘anyone’. It is a non-profit network of American doctors and hospitals, including two of the most prestigious medical teaching institutions in the country. From January to December 2025, a group of researchers from the institution they put 21 AI chatbots such as Claude 4.5 Opus, DeepSeek, Gemini 3.0 Pro, GPT-5 or Grok 4 to evaluate dozens of clinical cases with the aim of establishing their level of success in an early diagnosis. The information is extremely basic, but it is also what professionals have when making this differential diagnosis and the ultimate intention is to evaluate the clinical reasoning capacity of the latest generation language models to see if they can be a clinical ally. The answer is no. While models optimized for reasoning achieved much higher scores than simpler ones like Gemini 1.5 Flash, the bottom line is that LLMs are still limited for this task. The exam. Each of the models was given 29 clinical cases that represent more than 16,200 responses in total. The result is that these newer versions of the most powerful chatbots they couldn’t produce an adequate differential diagnosis in about 80% of cases when they only had basic information about the patient. The problem is that age, sex and symptoms is very vague information, yes, but it is one that human professionals who have to make this differential diagnosis ‘play’ with for the first time. Little by little, as they do other tests and obtain more information, they refine the result, but it is that first ‘discard’ treatment that often makes the difference. “We want to help separate the hype from the reality of these tools as they are applied to healthcare” another movie. And, precisely, as the LLM They were given more data, the performance and results were more robust. When the chatbot has more and more information such as physical analysis data, laboratory results and diagnostic images, things change and AI reaches the final diagnosis in more than 90% of cases. But of course, to reach that stage they must have almost all the clinical data, which further shows the gap with impotence when performing an initial filtering. Don’t trust Google ChatGPT. The researchers are clear that “these models are very good at identifying a final diagnosis when the data is complete, but they have difficulties at the beginning of an open case,” which leads them to emphasize that they should not be trusted at home. The AI ​​industry is pushing your product in the medical circuit, but the study points out that “despite continuous improvements, commercial LLMs are not ready for clinical implementation without supervision.” They state that a human is needed in the operation and “very close supervision” to be able to scale the use of an LLM in the healthcare field. And there they are always talking about professional use, but more and more cases are seen of people who previously treated themselves by trusting Google and who Now they do it trusting what ChatGPT tells them. In the study they emphasize that “hallucinations remain” in these latest generation models, also showing concerns about the safety and integrity of patients. About El Salvador. In any case, it is evident that, in the end, Medical AI is another helper, a tooland here what has been tested is a “common” chatbot that knows everything, but is not specialized in anything. In medicine, as in other industries, the use of AI can help with tasks such as eliminating possibilities or organizing thousands of data, but a chatbot is not yet a good companion in this differential diagnosis because it simply cannot be trusted. Those who are going to have to trust AI for any type of treatment are Salvadorans. El Salvador has been a pioneer country when it comes to adopting new technologies, and the president, Nayib Bukele, has just embarked on another experiment: $500 million to leave healthcare in the hands of Gemini. The population will have access to the app Dr.SV who will work as a family doctor. As detailed in The Countrythis AI will know the symptoms and will assign calls with doctors who will make the diagnosis. The AI ​​will monitor for consultations and chronic diseases and the goal is for it to take care of cancer patients in the future. According to Bukele, they are creating the best health system in the world, something curious considering that they laid off more than 7,700 health system employees during 2025. For the sake of Salvadorans, let’s hope that This new experiment does not end like Bitcoin City. In Xataka | Privacy is dying since ChatGPT arrived.

The oceans are smoking and the bad news is that that phrase is starting to stop being a metaphor

by

Global sea surface temperature is once again approaching 2024 records, Arctic ice marks its historic winter minimum and the average temperature is 1.43 degrees above pre-industrial levels. What’s more, the Earth’s energy imbalance has reached its highest level in 65 years. And all of this without El Niño being active. So I have to correct myself: what is happening is not that the sea is smoking. That’s a huge understatement. What happens is that the oceans have gone up a notch and we are completely caught out of the game. What is happening? According to Copernicus dataIn March, the global average temperature was 13.94 degrees. That is 0.53 above the 1991-2020 average and 1.48 above the pre-industrial temperature. It’s not the warmest March on record, but it’s close. In contrast, February 2026 was one of the three coldest in the last 14 years. And it’s curious because, anyway, we are in ENSO-Neutral conditions. The 2024 record was reached with El Niño pumping heat from the Pacific; Now we are in the most absolute normality. That does have experts from half the world worried. And the sea? In the sea things are more complicated because the surface temperature is very close to lrecord ace of 2024. Furthermore, it is not a question of a specific rebound: it is the result of a sustained rise throughout the entire month of March. There are specific areas (subtropical and northeastern North Atlantic, North and South Pacific) that are already at record values; The big question is what will happen at the end of the year and, above all, at the beginning of the year when El Niño is at its highest peak of intensity. Well, but this doesn’t affect us much, right? It depends on what we mean by ‘affect’, of course. What there is no doubt is that, despite the fact that temperatures are rising around the world, the Mediterranean has become the great laboratory for all detected and undetected climate risks. After all, Mare Nostrum heats up to 20% faster than the global average. And that has clear and direct consequences for water: from the mass extinction of vertebrates to the decline of grasslands to an enormous mortality of fish. Is a sea dying little by little; a sea that drags us with it: because the heat of the Mediterranean injects more water vapor and fuels extreme precipitation phenomena. The DANA of Valencia It’s a reminder of all this.. That is, the scenario is known. What remains is to see what we do to prepare for it.

We thought we were 8 billion people on the entire planet. Until some researchers started crunching the numbers

by

In November 2022, the UN celebrated that we were now 8 billion humans on Earth. They are estimates, of course, but beyond the figure, the really interesting thing is that in 2023 we do not reach the replacement rate and that humanity will reach its peak at the end of the century to, inevitably, start to fall. But… to what extent can we trust these accounts? It is something that has been on the table for some time and, according to a study of 2025, we have made a mistake in counting. So much so that we have left several hundred million people behind. Can we trust the numbers? “Calculating the number of people on the planet is an inexact science.” That was demographer Jakub Bijak’s comment to BBC in mid-2024, just when the World Population Prospects study. Something scientific is something exact, but the researcher also commented that the only thing you can be sure of when predicting population figures is the lack of certainty. That, be careful, does not mean that demographers take figures out of thin air. “It is a difficult thing based on our experience, knowledge and every piece of information we have access to,” said Toshiko Kanera, an expert in demographic forecasts. Demographers draw on the data and trends of each country since 1950, but… what if it had not been counted correctly? We are missing millions. In a 2025 study published in Natureresearchers at Aalto University in Finland show how the data sets handled by demographers “profoundly and systematically” underestimate population figures around the world. The serious thing is that we would be talking about hundreds of millions more people living on Earth. Example of the tools that demographers use in their analysis. Each one corresponds to a different bias Rural areas. Josias Láng-Ritter is one of the researchers in charge of the study and points to the accounts carried out in a specific segment: that of rural population. “For the first time, our study provides evidence that a significant proportion of the rural population could be missing from global population data sets,” he notes. As we say, we are not talking about a few million, but billions. “Depending on the data set used, rural populations have been underestimated between 53% and 84% in the period studied. The results are notable, since these data sets have been used in thousands of studies and have widely supported decision making, but their accuracy has not been systematically evaluated,” comments the researcher. The map shows the location of the 307 rural areas analyzed in the study. The populations reported in the graph were found to be underestimated by between 53% and 84% | Aalto University Biases. Attempts to review this data are not new, but previous research has focused on specific countries or urban areas. Researchers from Aalto University wanted to give a more global picture by comparing the five most used population data sets worldwide. They have used maps that divide the planet into high-resolution grids and have taken something very specific as a reference: resettlement figures from more than 300 rural dam projects in 35 countries. Why this bias of the dams? Because when a dam is builtthe population that lives in the area that will be flooded is relocated and accurate resettlement data is usually available. Comparing that population data from 1975 to 2010, the researchers found that the 2010 maps were more accurate, but still left out between 32% and 77% of the rural population. Between 2015 and 2020 the data sets were updated, but demographers continue to believe that underestimation of the rural population continues to exist and is a problem that persists in all regions of the world. Consequences. And we are talking about a problem whose resolution is complex. According to the researchers, no matter how much the data is reviewed, it is a structural problem. Governments do not have the resources to collect accurate data in these rural regions, there is a huge discrepancy between the real population and that reported on the population maps used to carry out demographic studies and that influences decision making. Average percentage of rural population underestimated (red and orange) and overestimated (blue) | Aalto University And it’s important. Current estimates place 43% of the 8.2 billion inhabitants of the world in rural areas -about 3,526 million people- and if we take into account that it is a percentage that has been underestimated between 53% and 84%, we are not talking about a small population, precisely. And it is essential to know exactly how many we are for a simple reason: the redistribution of resources. No data. The lack of accurate demographic records can affect political decision-making. Ritter gives the example of social decisions. “In many countries, there may not be enough data available at the national level, so they rely on global population maps to support their decisions: Do we need a paved road or a hospital? How much medicine is needed in a specific area? How many people could be affected by natural disasters like earthquakes or floods?” he says. Doing quick math, in the best scenario – that of 53% deviation in the rural population – we would be talking about 1,869 million people who would not have been counted. In the worst case, in that of the 84% not registered, we would talk about 2,962 million people. In the Nature study, they give the example of Paraguay, which in the 2012 census may have left out a quarter of the population. Reviewing the methods. In the team’s analysis, there are countries that fare better than others. They point to Finland as an example of reliable data, even in rural regions, because they began keeping digital records of the population 30 years ago. However, in countries where this thorough digital registration has taken longer to be implemented due to crises of any kind, the differences between the real population and the estimated one can be significant. “To provide rural communities … Read more
