We have been thinking for 40 years that Spain escaped Chernobyl because it was far away. AEMET has discovered that it was pure luck

by

“When the lava enters the tanks, it will cause approximately 7,000 cubic meters of water to overheat and evaporate, causing a significant thermal explosion. Our estimates are between two and four megatons. It will destroy absolutely everything within a 30-kilometer radius, including the three remaining reactors at Chernobyl. Then, all the radioactive material in the nuclei will be ejected with virulence and propagated by a large seismic wave. It can reach approximately 200 kilometers and could be lethal to the entire population of kyiv and much of Minsk. The radiation release will be immense and will impact Soviet Ukraine, Latvia, Lithuania, Belarus, as well as Poland, Czechoslovakia, Hungary, Romania and East Germany.” Since, to celebrate the 40th anniversary of the Chernobyl disaster, AEMET published meteorological reconstruction that explained why Spain was left out of the radioactive cloud that affected a good part of Europe, I can’t forget those words from the miniseries which HBO released a few years ago. Mostly because it was pure luck. Pure luck? But Ukraine is very far away. That’s what we used to think, that Spain was spared the hardest part of the Chernobyl hit because we were so far away. However, data from meteorologist Benito Jose Fuentes They say something else: three successive atmospheric reconfigurations that, at the critical moment, sent the radioactive cloud in another direction. But let’s go step by step. Indeed, on April 26, 1986, the Chernobyl nuclear power plant became an unstable “pressure cooker” whose explosion spread radiation throughout much of the continent. In fact, that radiation reached Spain shortly after: there is evidence of air filters in Valencia that detected the radioactivity on May 2, 3 and 4. However, we avoided the worst of the blow. According to Fuentes Lópezthe peninsula was at least twice (on April 29 and the days before May 2) “one turn of the wind” away from receiving a direct blow. Reconstructing the disaster. Sources Lopez has published a simplified simulation that reconstructs on a cartographic scale the evolution of the wind at medium and high levels of the atmosphere. This simulation is what gives us the fundamental keys. To begin with, at midday on April 26, a high pressure ridge extended between the Chernobyl zone and Scandinavia. This caused the winds (at 1,700 meters above sea level) to channel the pollutants to the north and Belarus, the Baltic republics, Sweden and Finland took the first hit. The world found out what was happening, precisely, through the sensors of a Swedish nuclear power plant two days later. Spain plays it. On April 29, the pattern changed and a storm in the Mediterranean (and a ridge in Portugal) turned the wind towards Central Europe. According to Fuentes López’s simulations, with this new direction it was a matter of hours before the radioactivity reached Spain. However, between May 1 and 2, a trough pushed the radioactive cloud towards Great Britain (and the Portuguese ridge acted as a wall that diverted the rest of the smaller clouds towards Italy and the Balkans). A reminder. The curious thing about all this is that, according to AEMET datathe dispersion was due to higher atmospheric waves at high levels and not to surface patterns such as storms and anticyclones. That is to say, the work (in addition to a mind-blowing work of atmospheric history) is a reminder that we normally relate to a small part of the weather. That, of course, is a mistake. The atmosphere is a very complex creature full of levels, teleconnections and strange relationships. We are at stake understanding it better. And I am no longer talking about climate change, or phenomena of that type. I’m saying that in most cases, as we already explained many expertsthe profound psychological, social and cultural consequences “turned out to be a much bigger problem than the radiation.” At the climatic level they will also be. And we really don’t know how to handle them well. Image | AEMET In Xataka | We believed that the “elephant’s foot” was the most radioactive point in Chernobyl reactor 4. we were wrong

how to declare them and in which cases you must do so in the 2026 declaration

by

Let’s explain to you how to declare your cryptocurrencies in your Income 2025, which is the declaration we make in 2026 to account for the last fiscal year. You can now request and submit your draft online and from the mobilebut first it is advisable to pay attention to this. Let’s start this explanation by telling you in which cases you should declare your cryptocurrenciesso that you take into account if you have to do it. And then we will tell you the way in which you should enter them in the Income Tax return and the particularities of how they are declared. When should you declare your cryptocurrencies What you have to declare is everything you have won or lost in 2025 with the sale and exchange of cryptocurrencies. You must also declare when you exchange a cryptocurrency for a good or service, come on, when you have used them to pay for something. They are taxed like sharessuch as capital gains or losses. You have to declare all transactions, whether they generate profits or losses, regardless of the amount. This applies whether you mine cryptocurrencies or trade to buy and sell them. This is so because They are considered a part of your heritage and your income, and this makes them equivalent to when you earn money doing a job or selling stocks. It is important to make sure you declare everything, because You can have fines of up to 20,000 euros. If you do not declare movements, you will be fined around 20 euros for each undeclared data up to that figure. And if you declare incorrect data or data is omitted, the fine is 150 euros, although with the possibility of increasing to 0.5% or 1.5% of the amount of the operation. Losses or profits are calculated by the difference between the transfer value or the value at which you sold them and the acquisition value. You must also declare airdrops, which are those cryptocurrencies that a website can give you. exchange in exchange for registering or doing some operations in them. Besides, mining is also declaredand since it requires material or personal means to carry it out, it is an economic activity. Come on, you must register as a professional or businessman, and then declare the profits or losses by subtracting operating expenses such as electricity, equipment and so on, and the rewards or benefits obtained. How to declare cryptocurrencies Cryptocurrencies are declared in a specific section. You will have to use boxes 1,800 and 1,814, which detail the movements and operations carried out that are related to cryptocurrencies. When declaring the movements, you will have to write the name of the cryptocurrency, the key or what you have done with this asset, the value of the acquisition and the value of the transaction. And so with each of the movements you have made. For balances or holdings of cryptocurrencies abroad above 50,000 eurosyou will also have to fill out form 721. In addition, if the crypto balance abroad grows by more than €20,000 compared to the previous declaration, you must submit it again. Profits obtained are taxed in different ways depending on how much they amount to. They are taxed on the savings tax base, and these are their tax rates: Personal income tax of 19% for benefits of up to 6,000 euros. Personal income tax of 21% for benefits between 6,001 and 50,000 euros. Personal income tax of 23% for benefits between 50,001 and 200,000 euros. Personal income tax of 27% for benefits between 200,001 and 300,000 euros. Personal income tax of 30%: for benefits of more than 300,001 euros. Another thing to keep in mind is staking. If rewards are received for transferring the coins to a platform, it is considered a return on movable capital, which is taxed on the savings basis at a rate of between 19 and 30%. Meanwhile, if it is done as an economic activity, it is taxed on the general basis at rates that can range between 19% and 47%. Rewards obtained by staking are valued in euros at the time of receipt. You should also know that the Treasury uses the FIFO (First In, First Out) method. This means that the first cryptocurrencies you bought will also be considered the first to be sold. Additionally, if you suffer losses from cryptocurrencies you can offset them with other capital gains from the same return.

A young man has solved a mathematical problem that lasted 60 years in 80 minutes with ChatGPT. That’s the least interesting thing about the story.

by

He is 23 years old, his name is Liam Price and he has no advanced mathematical training. Even so, a few days ago he opened the Erdös problem websitepicked one at random and pasted it into ChatGPT. I didn’t know the history of the problem or who had tried it before. What he received back seemed like a good solution, and after consulting with a friend who was studying mathematics, the two realized they might be on to something special. A few hours later Terence Tao, one of the most renowned mathematicians in the world, confirmed that problem #1196 of Erdös, a conjecture about primitive sets of integers that had not been solved since 1966, had a solution. I had found her GPT-5.4 Pro in just 80 minutes. Not like that. This problem analyzed a question about the behavior of a particular mathematical sum on primitive sets, that is, sets of integers where none divides the other, when those numbers become very large. Jared Lichtman, a Stanford mathematician, had spent years on the problem and had made partial progress, but he and those who had tried before were starting from the same starting point that seemed like the right path. A novel idea. GPT-5.4 used another starting point. He stayed in the airmetic terrain and used a special function called von Mangoldt functiona classic tool of number theory known for its connections to prime numbers and Riemann zeta function. No one had thought about that approach to the problem, and as Lichtman explained when talking about the OpenAI model solution, “The LLM took a completely different route.” The achievement is real, but with nuances. Litchman praised the proposed solution by GPT-5.4, but there is one detail that has been omitted in many comments on this event: the raw output of ChatGPT was, in the words of this mathematician, “pretty poor.” This solution made it necessary for several experts to interpret it, detail it and extract from it the underlying idea that allowed the conjecture to be solved. Price didn’t know he had the solution until his friend read it, and he wasn’t sure until Tao confirmed it. The official repository of AI contributions to Erdös problemsmaintained by Tao himself on GitHub, classify the result as a solution generated in human-AI collaboration, not as a solution developed solely by AI. The distinction is important. A previous scandal. A few weeks ago Sebastien Bubeck, a researcher at OpenAI, posted on X that GPT-5 had “solved” several Erdös problems. That publication exceeded 100,000 views, but the mathematical community and also that surrounding the AI ​​industry criticized that statement. Demis Hassabis, CEO of DeepMind, called that statement “shameful.” What had actually happened is that the model I had found solutions to already solved problems on the web. Bubeck finished deleting the original tweet and tried to back down, but all this raised doubts about the validity of the application of AI to solve mathematical problems. AI and the mathematical success rate. Terence Tao and Nat Sothanaphan maintain the aforementioned record of all AI contributions to Erdös problems on GitHub. Each of the entries in that list or table is classified with a traffic light: green for complete solution, yellow for partial progress, and red for failure. In the category of completely AI-generated solutions with no known prior literature there are three green, fourteen yellow, and eight red traffic lights. However, the repository itself adds a unique comment: those who try to use AI to solve these problems and fail do not usually report it, so it is likely that AI has been applied “silently” to a large number of these problems without success, and those attempts do not appear in any table. There is a clear bias here because only successes generate headlines. Trying to measure what matters. In February 2026, eleven mathematicians created the initiative “First Proof“. In it they included ten mathematical problems that arose naturally in their research projects. For each one they included encrypted answers uploaded to a verification site, and they gave the AI ​​systems a week to try to solve those problems that had never appeared in any training data set. Preliminary results indicate that today AI models cannot overcome that barrier autonomously, and what happens is that there are still limits to what AI can really contribute in mathematics. But then, is there a revolution or not? Terence Tao offered a clear explanation as to why GPT-5.4 had succeeded where others had failed for 60 years. What had happened was what he described as a collective blockage of the mathematical community, because everyone started from the same origin because it was “the natural one”, the one marked by tradition. The AI ​​didn’t know that was the “correct” way to start, and that ignorance turned out to be an advantage. It’s not that the AI ​​was smarter, it’s that it had no biases about how to approach the problem. Now it remains to be seen if this novel way of trying to solve problems in unorthodox ways works. This will confirm whether what happened with Erdös’s problem number 1196 was an isolated case or whether a 23-year-old boy has managed to change our vision of how to tackle mathematical problems.

a poacher, two 200 kilo specimens and a stratospheric fine from the Civil Guard

by

On April 20, the Civil Guard detained a professional fisherman in the port of Águilas (Murcia) with two freshly caught bluefin tuna. Each piece weighed a few pounds and the guy had no specific authorization, he had not communicated either his departure or his entry into the port and, of course, there was no trace of traceability documentation. With Law 3/2001, of March 26, on State Maritime Fisheries in the hand, the fisherman is exposed to a fine of up to 600,000 euros for what would be the most expensive kilo of tuna in the world. The story, however, is more interesting. That great success called ‘bluefin tuna’. Atlantic bluefin tuna is one of the great fishery management successes of the 21st century. It has gone from being on the brink of collapse in 2007 to be declared by the IUCN as a species of “least concern” in 2021. I don’t want to exaggerate, but it is something amazing. And the sanctioning regime has had a lot to do with it. Because we don’t even need to remember it, but tuna fishing (even today) is full of irregularities. Understandably, on the other hand. Because, whether we like it or not, the success of tuna recovery has made poaching easier and more profitable than before. Let us keep in mind that, at the beginning of the year, Japan Tuna was auctioned at 11,500 euros per kilo. Obviously, it is an exceptional case, but it gives an idea of ​​the perverse incentives generated by the black market. The striking thing is that what SEPRONA has “hunted” in Águilas cquadruples the legal annual fee that the ships of the Region of Murcia have assigned. Can we do better? We’re not doing it wrong, really:The figures speak for themselves. But the situation is very complex. It makes no sense that recreational bluefin tuna fishing in Spain has become a race to go fishing first. In the last five years, the longest effective fishing season was seven days in 2021. That is, it took fishermen a week to accidentally kill so many tuna that the fishing ended. In 2022 and 2023 there were five days and In the following years, three. Above all, because we know that with tougher regulations this doesn’t happen. We are working on it. Not everything we need, but it’s something. This January it came into force a regulation that tries to digitize the capture record and close the “statistical black hole”. The experts are worse They are not very optimistic either.. They fear that the pressure will grow year after year and that we will not go fast enough. Come on, either we step on the accelerator or things are going to get more and more complicated. And, in the end, the solution will only come when the current system bursts at the seams. It wouldn’t be something exceptional: we are specialists in it. As I said, the good news and the bad news are the same: that this will happen soon. Image | Peter Lam CH In Xataka | Spain is going to continue fishing for eels until we have no more eels to catch

It seemed difficult for China to compete with the US as a global tourism power. And yet it’s happening

by

Although tempers have cooled after the war in Iran and the doubts about what impact it will have on the sector, in general international tourism is experiencing its ‘roaring 20s’. Families have come out of the pandemic break wanting to pack their bags and get to know new countries, something that has not taken long to be noticed by the UN tourism observatory, which last year registered an increase of 4% in the flow of international travel, as in the World Travel and Tourism Council (WTTC), which estimates that the sector represents almost 10% of global GDP. The increase, however, has not been equally strong around the world. What’s more, WTTC itself has noted important differences in the two large economies of the sector, the US and China, which could precipitate a surprise historical. I like to travel. The world has emerged from the pandemic with a desire to travel. Many. It is a trend that has already been noted in 2024when pre-COVID levels were recovered, and has continued to consolidate over time, which explains, for example, that Spain is bordering on the historical barrier of the 100 million travelers a year or that Japan gives clear samples of saturation. According to the latest calculations of the WTTC, 2025 was “the best year in history for the sector”, at least as far as economic growth is concerned. Its contribution to world GDP exceeded 10.7 billion eurosabout 10% of the global economy, and supported almost one in ten jobs worldwide. These are compelling data not only because of their scope, but also because of the trend they show: in general the tourism sector is growing more than the international economy. The US slows down. The ‘photo’ is not, however, equally good in everyone. The WTTC technicians have noticed a weight loss in the main economy tourism on the planet, the American one. Although the country governed by Trump remains “the largest travel and tourism market in the world”, the truth is that it is losing market share. The data is resounding: while the sector grew at 4.1% overall, in North America that percentage was four times lower (1%). In fact, it was the “slowest growing region in the world.” The balance was even worse in the US, with an increase of 0.9%. A key fact: 5.5%. “In 2025, eighty million more people took international trips compared to the previous year, although they chose other destinations. The number of American visitors decreased by 5.5% compared to 2024 and spending by international visitors decreased by 4.6%, reaching $176 billion,” they point out those responsible for the WTTC. His analysis joins others that in recent months have warned of a setback in the flow of foreign tourists arriving in the US and the loss of attractiveness in key markets. For example, the country’s Department of Commerce registered in 2025 a drop of 20.9% at the entrance of visitors from Canada. In 2024 it had already registered a decline, but of only 1.3%. Why is it important? For what it means for the American tourism industry. And for its implications in the sector worldwide. As the WTTC reminds us, today the US continues to be the economy that more money moves thanks to tourism and travel, with a notable advantage over the second On the list, China: the US moves at 2.63 trillion dollars while the Asian giant is around 1.75 trillion. How has the US achieved that weight in the sector? Thanks to two legs: the local market, the trips that Americans make when traveling from one city or state to another, and the arrival of foreign visitors. If we look at the latest reports from the US Travel Association and the WTTC, the first leg continues to respond well. In 2025, Americans they accounted for 87% of the country’s tourism business and increased their contribution to the sector. Their spending was 14.3% higher than pre-pandemic levels. Things change, however, when we look at the arrival of tourists from other countries: their flow was reduced by around 2.3% and their spending indicators are also not good when compared to those the country managed before COVID. Losing “hook”. This loss of attractiveness among foreigners coincides with a hardening of the conditions to enter the US and news about arrests in airports, which even led some European embassies to give guidelines to its citizens to avoid surprises with their visas. Another key factor was the international policy deployed by the White House, which strained relations with countries such as Canada and Denmark. The decisions made by the Trump administration soon gave rise to campaigns that advocated boycotting American products, something that was felt in tourism. In January WTTC itself warned Washington that if it finally approved the new requirements it had on the table for ESTA authorization applicants, which included a thorough review of tourists’ online activity, it risked losing just over a third of its visitors. “34% of those surveyed say they are less likely to visit the United States in the next two or three years if the changes are implemented,” he warned. China on the prowl. It is not just that the US sees its market share in international tourism shrink, it is that everything indicates that China will take advantage of this situation to cut positions. “While the US contracts, China grows at a dizzying pace,” explains Gloria Guevarapresident and CEO of WTTC to Bloomberg. “If this continues, in three or four years it will reach the US.” In another interview A recent interview with USA Today even went further and warned that, if the current situation continues, China will end up “replacing” the US as the world’s main tourist market in a matter of four years. today the gap Between both markets it is enormous (the US sector contributes 2.63 trillion dollars and the Chinese 1.75), but Beijing is growing at high speed. WTTC estimates that its tourism sector is growing at a rate of 9.9% and that, unlike what … Read more

TSMC is not going to use its High-NA machines at the moment and has a compelling reason not to do so

by

On April 23, TSMC made official a strategic decision very important: has postponed the adoption of ASML’s extreme ultraviolet (EUV) and high aperture lithography machines until 2029. These are the equipment of manufacturing of more advanced integrated circuits that this company from the Netherlands currently has in its portfolio, and TSMC’s announcement caused ipso facto a drop of 3.3% of the value of its shares. It is not in vain that this Taiwanese chip producer is ASML’s largest client. In 2025 23.9% of total sales of this Dutch company came from TSMC. The main reason why this last company has decided not to use UVE High-NA machines of ASML in the short term is strictly economic. Each of them has a price of around 350 million euros, and, in addition, a single cutting-edge semiconductor plant requires the installation of several dozen of this equipment. TSMC considers that they are currently too expensive to make the manufacturing of advanced chips profitable. And, interestingly, Intel, Samsung and SK Hynix they are already adopting High-NA technology. This decision by TSMC brings great technical challenges The step taken by TSMC has not been improvised, as might be expected. In fact, over the past two years several managers at this company have publicly expressed doubts about the short-term adoption of ASML’s High-NA equipment. In January 2024 CC Wei, the current president and CEO of TSMC, surprised us with this statement: “We are studying it carefully, evaluating the maturity of the tool and examining its costs. We always make the right decision at the right time in order to offer the best service to our clients,” Wei assured. during a meeting. A few weeks earlier Szeho Ng, an analyst at China Renaissance, predicted that TSMC would not use ASML’s high-aperture UVE equipment until it introduced its 1nm integration technology. “We always make the right decision at the right time with the purpose of offering the best service to our clients” Last week it was Kevin Zhang, TSMC’s deputy chief operating officer, who clarified something very important: “I am amazed by our R&D team. They continue to find ways to drive technological development without using ASML’s High-NA UVE equipment. Someday we may have to use them, but right now we can continue to reap the benefits of current EUV technology without moving to High-NA which, as we all know, is extremely expensive.” In 2029, TSMC intends to have the A12 and A13 integration technologies ready for large-scale production, which are nothing more than derivatives of its A14 photolithography. From a commercial point of view these will be the first 1.2 and 1.3 nm technologies of this company. They will use GAA transistors (Gate-All-Around) and NanoFlex Pro technology. This latest innovation will allow IC designers to use fast cells for the critical parts of the GPU that need speed, and dense or efficient cells for the rest, thus optimizing the chip area down to the last millimeter. What we still do not know is what technical solutions TSMC engineers are going to implement to make it possible to manufacture 1.2 and 1.3 nm integrated circuits using ASML’s UVE equipment. It’s just a guess, but it seems unlikely that they will resort to the multiple patterning because this procedure compromises the performance per wafer and the cost of the semiconductors. TSMC would lose competitiveness. One last note: the multiple patterning Broadly speaking, it consists of transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process.

a plane that shoots drones

by

During the Afghanistan Warthe Soviet forces resorted on more than one occasion to adapt helicopters and airplanes transport for improvised functions in combat, from close support to surveillance platforms navy. Then they made it clear that even in highly structured armies, the need on the battlefield forces them to reinvent machines that were never designed to fight. An unlikely plane that changes the rules. In the midst of a war largely dominated by drones, Ukraine has found an unexpected solution in a Soviet-era relic: the Antonov An-28a light transport aircraft that has been transformed or “tuned” into something completely different. Far from its original function, this twin-engine now acts as an unprecedented aerial offensive platform capable to launch interceptor drones from its wings, becoming a kind of improvised “drone carrier.” This adaptation is not an isolated experiment, but part of an accelerated evolution in which old systems they reinvent themselves to respond to modern threats, giving rise to a key idea: air combat no longer depends only on missiles, but also on cheaper, more flexible and replicable systems. From ammunition to drones. Until recently, An-28 crews were dedicated to shooting down enemy drones with machine guns from the aircraft itself, a rudimentary but effective tactic that had already achieved hundreds of kills in battle. However, the qualitative leap comes when integrating interceptor drones like the P1-Sun either the AS-3 Surveyor under its wings, devices capable of pursuing and destroying objectives autonomously or guided. In this way, the plane is no longer just a direct hunter, but a range multiplier which deploys “cheap missiles” in the form of drones, capable of impacting or detonating near the target, greatly expanding the possibilities of interception. The economy as a weapon. One of the most determining factors of this innovation is, again, the cost. It we have counted before: faced with enemy drones or missiles that can cost tens of thousands of dollars, Ukrainian interceptors are significantly cheaperespecially if they are produced on a large scale. This difference changes the logic of combat, because it is no longer about spending more to defend yourself, but rather about finding ways to neutralize threats. at lower cost. Not only that. The An-28 It also allows you to bring closer those interceptors at the target, launching them from height and speed, which improves their effectiveness and reduces reaction time, reinforcing a more sustainable air defense. A more flexible and extended air shield. There is no doubt, the use of the airplane as an aerial platform offers quite clear operational advantages. can patrol for long periodsquickly position yourself in risk areas or even operate from improvised runways thanks to its short takeoff capacity. Besides, combine multiple tools: drones, light weapons and potentially other systems, creating an adaptable defense against different types of threats. In a context where Russia produces thousands of drones per month and develops increasingly faster models, this flexibility becomes essential to maintain balance on the battlefield. Towards a new air combat doctrine. If you also want, what is happening with the An-28 is not just a tactical adaptation, but an indication of where modern warfare is headed. The idea of ​​launching drones from other platforms, whether airplanes, helicopters or even unmanned systems, opens the door to a combat model much more distributedwhere multiple layers of defense work in a coordinated manner. Seen this way, in the new scenario the value does not reside solely in power or sophistication, but in the ability to combine simple, scalable and economical solutions to counter massive threats, redefining what was understood until now as the traditional concept of air superiority.

What is Claude’s graphic design tool and how does it work?

by

Let’s explain to you what is Claude Designa new function within the chat artificial intelligence of Claude. It is a graphic design tool with which you will be able to create all kinds of interactive elements and then shape them until they are to your liking. We are going to start by describing what exactly this tool is, so that you know all the possibilities it offers you. And then we will explain to you in a quick and simple way how it works. What is Claude Design Claude Design is a visual creation tool through conversations created by Anthropic for Claude. It’s something similar to Canvabut with artificial intelligence. What it does is allow you to do visual work with prompts instead of starting from scratch from a blank piece of paper. We could say that it is something like a graphic designer using artificial intelligencewhich allows you to order creations without needing to know Figma, Photoshop or any other similar program. It’s something like the Claude Code for graphic design. Claude Design allows you to make many types of design, such as from websites and applications to Power Points or animations. You will even be able to configure your own design guide, in addition to all kinds of interactive prototypes and presentations. These are the things you can do with this tool, according to Anthropic: Realistic prototypes: Designers can turn static mockups into easy-to-share interactive prototypes for feedback and user testing, without needing to review code or submit pull requests. Product diagrams and mockups– Product managers can outline feature flows and pass them to Claude Code for implementation, or share them with designers for refinement. Design Explorations– Designers can quickly create a wide variety of proposals to explore. Presentations and sales materials: Founders and account executives can go from a rough sketch to a full, on-brand presentation in minutes, then export it as PPTX or send it to Canva. Marketing materials: Marketers can create landing pages, social media assets, and campaign visuals, then involve designers to polish them. Cutting-edge design: Anyone can create code-based prototypes with voice, video, shaders, 3D, and built-in AI. Claude Design is currently in version Research Preview. This means that it is a trial version that has not yet reached beta nor is it available to all users. One of the particularities of Claude as an AI is that it focuses on offering useful functions for the user, but leaves aside others more focused on entertainment such as image creation. This has been a problem for professionals who use AI to create an image, and it is the gap that this tool tries to fill. Claude Design is powered by Claude Opus 4.7, which is currently the latest version of the Claude AI model. At the moment it is only available for Claude Pro, Max, Team and Enterprise subscriberswho are the only ones who can test this functionality. How Claude Design works Claude Design works through textual prompts, combining conversational and interactive logic. This means that combines a chat interface with an interactive canvas located on both sides of the screen, always in view of the user. With this, you will first write what you want to achieve, describing everything in a prompt, and Claude will generate a first version. And then, you’re going to have controls to refine the resulteither through textual instructions or with interactive buttons. To start you will have to create a prototypewhich will be the way to create a new design. This will take you to the main Design window, where on the left you can give commands and on the right you can interact. You will be able to start in several ways, such as loading external files which can be screenshots, Figma files or code, or even just describe what you want with a prompt to which you can attach designs. You will even be able to start from a drawing that you do freehand on the right side with the option of Start with a sketch. The idea is that just by having something in mind you can start creating it. Once you have created the first draft of what you want, you can continue using the left column to give instructions for the things you want to change. you also have options like Tweaks and Comments. The first allows you to create manual controls describing what you want to do with it. For example, bars to resize the parent element. And the second allows you to make concrete changes to specific components instead of the structural changes you make with prompts. and then you have the edit button or Editwhich allows you to choose an element of your design and make changes directly to it. In addition, you can also draw other elements by hand with the option Draw. In short, you have all the options to to be able to shape your design using a combination of manual and artificial intelligence controls, and even being able to create manual controls with AI.

C-3PO had a boner in 1977 and was seen on thousands of trading cards. Until the parents realized

by

As is well known, ‘Star Wars‘ was revolutionary in 1977 on many levels, but in no way was it more so than in merchandising. The story of the action figures and how Kenner beat Mattel by taking over the exploitation rights to the franchise is the most popular part of the story, but there are many other crazy anecdotes in a field that was literally beginning to be sown. For example, Topps launched a collection of trading cards with a very peculiar copy: 207 of the fourth series, with a nondescript image of C-3PO emerging from an oil bath. It lasted until the parents took notice. The sticker war. Sticker rights They were also disputed very briefly, as was the case with the action figures. Donruss, a company with experience in science fiction trading card collections, had the first option on the license and rejected it. Topps came in after some hesitation, put out a first series and watched it run out at an unprecedented rate. Five series later in 1977 alone, the film was still in theaters, and the company had to launch, with almost no time for revisions, series after series. For the fourth, the available photographs were almost the same as those already used in the first two, and that was where the problem arose. C-3PO oily. The controversial photograph showed C-3PO emerging from an oil bath. At first glance nothing seemed scandalous, but if you paid attention, the protocol droid seemed to have bypassed protocol with a large metallic appendage. The chrome earned its own nickname, “Golden Rod.” Parents’ complaints They didn’t take long to arrivethe letter was withdrawn and an airbrushed version produced. What happened really. There are three versions about the reasons that led to the error. The first, when in 2007 the official ‘Star Wars’ website published an explanation later removed: It was an optical effect because at the exact moment the photo was taken, a piece of the suit came off and was aligned in a way that suggested the obscene image. In his book ‘Star Wars: The Original Topps Trading Card Series, Volume One’, author Gary Gerani raised another theory: someone from the prop team on the set had placed a metal appendage as a joke between colleagues. Because. The most detailed explanation was given in 2019 by Anthony Daniels himself, the android’s interpreter, in promoting his autobiography ‘I Am C-3PO: The Inside Story’. According to the actor, the oil was real and C-3PO’s suit at that time consisted of two pieces of thin plastic (front and back) joined with gold-colored adhesive tape. The oil dissolved that tape and when Daniels left the bathroom, the pieces separated and formed a crease in the crotch that created the bulge. Additionally, the actor believes that a Topps employee, when processing the photograph, identified the crease and deliberately accentuated it. Error wanted. Paradoxically, the corrected version of chrome 207 is today rarer than the original. There are more than 1,800 copies of the card with the error compared to less than 700 of the amended version, since the error circulated for months before being removed, and the correction arrived at the end of the fourth series, with smaller print runs, and was quickly eclipsed by the fifth series. And how much is it worth? In medium condition it costs 30 or 40 dollars, but in good condition it can exceed 5,000. By the way: Daniels has systematically refused to sign the error card. Any copy with his autograph is a fake, he says. In Xataka | This Star Trek movie was canceled in 1977 because science fiction had no future.
