This is how they managed to endure the cold

Let’s start at the beginning: although it may seem like perogrullo, In the Middle Ages it was cold. It was cold, but not so much. At least, in Europe, there was a warm period (the “Climate optimal“) that systematically relieved the living conditions of the Europeans of the time. But around 1300 the thing changed radically: the Small Middle Ages He had started. Was A disaster. And not only because of the cold, epidemics and the loss of entire crops, it was that European peoples did not have the necessary technology to warm themselves at home without putting their lives at risk. No radiators, without chimneys, without crystals in the windows … the houses of the continent became unhealthy mousetracks full of associated risks. And how did they warm up? That is the question that The history and disseminator professor Nuisia RARRIDI is made. After all, no matter how cold the temperatures of western Europe did at that time they had to be terrible. AND, As Raridi says“The houses were permanently crossed by air currents.” We talk about a time when we had to “choose between leaving the light and the cold or neither.” There weren’t windows? There were, of course. They were small and normally had no crystals. As Raredi explainedthe glass for the windows “appeared in the cathedrals around the 10th century.” Before that (and later), it was common relativamene to see churches that used basalt to try to solve the problem of light. Because the glass problem is that it was expensive. In fact, it was not until after 1300 (when the techniques had improved and the cold began to accentuate) when they began to be used in private homes – especially in accommodated houses. And the issue of fire? How were there no chimneys? According to the documentation that He has collected RARRIDI“The chimneys, as we understand today, did not develop before the thirteenth century.” Until that time, as we can see in many places on the planet, the families lit fires in the center of the house and, consequently, the smoke filled the entire room (and went out where it could). As if that were not enough: the homes were very badly isolated. “The medieval houses were often made of wood and were poorly isolated”, which meant “a real problem in the coldest months.” Hence the tapestries, carpets and canopy beds were popular (which, “were extremely practical: the curtains that surround them served to retain heat and protect themselves from cold”). It doesn’t hurt to remember that for centuries, Europeans slept within cabinets and the explanation to her is this same. Cold, heat and vice versa. Despite what Paleoclimatic discussion has become popular for the debates of Climate changeright now we don’t have much to learn about medieval techniques to pass the cold. However, knowing what we were, always helps expand the imagination about how the human being can live. Image | Krzysztof Kowalik In Xataka | The Middle Ages was not as dark as they told us

Elon Musk has been cutting the US government for weeks. Yesterday Milei gave him a chainsier to celebrate it

Javier Milei is not going through the best of his political moments after the second accusation of fraud with cryptocurrencies of his career, for the controversial public support of the president of Argentina to The cryptocurrency $ libra. Milei has chosen to get away from all that controversy and travel to the US to personally give Elon Musk the Symbol of cuts In his legislature: a chainsaw. For his speech, in addition to the chainsaw, Elon Musk wore large sunglasses, gold chains around his neck and a black magician cap, alluding to The Musk Meme generated by AI that have circulated through their social network since the Doge project was known. Sunglasses and chainsaw in a political scenario Elon Musk was not planned to participate in the Conservative Political Action Conference (CPAC) that the Republican party is celebrating near Washington, but finally, an effusive Elon Musk took the stage for Rob Schmitt, a Newsmax presenter, to do an interview of which The Verge has published a transcription. The millionaire took the stage dressed in a shirt in which you could read “I am not postponing anything, I am doing secondary missions”, a thick gold chain, black magician cap and huge sunglasses that hid their eyes during the entire interview . Musk He entered greeting to an audience delivered and effusively raising their arms, although without Make Roman threats In your celebrations. After the initial greetings, Musk exclaimed: “President Milei has a gift for me”, just before Javier Milei entered the scene giving the magnate a chain that Musk did not hesitate to fly euphoric exclaiming: “This is the chainsaw of the bureaucracy!”. An interview that raised suspicions After the delivery, the Argentine president was completely ignored by both Elon Musk and the presenter, so he went to the back of the stage resisting to abandon him without saying goodbye to the millionaire, who continued to stir the chainsaw from one end to the other of the stage. Completed the “Performance” of the chainsaw, Elon Musk and the presenter set out to start an interview. Musk broke the ice confessing: “I have become a meme” and “My mind is a storm.” Faced with the journalist’s questions, Musk answered babbling and with certain difficulties in articulating complete phrases, forcing the presenter to guide Musk’s answers during his interview. This behavior did not go unnoticed to the audience, which immediately shared it into a wave of messages, turning the word “Ketamine“In tendency in X during his speech.” Elon can barely form a prayer at this time, ” wrote The journalist Aaron Rupar in his X account. The legal analyst Ken White, too He showed his surprise Given Musk’s difficulties to maintain a fluid conversation. The comedian Gabe Sanchez went a little further pointing to the origin of the problem: “POV: you just took a ton of ketamine and went on stage,” wrote on his X profile. It is not very common to see Elon Musk doing an interview with sunglasses. Previously, Musk had received Javier Milei in one of the private rooms of the Convention Center where the Republican event is celebrated. In a Video of that meeting Published by Javier Milei, it can be seen how the Argentine President enters the stay. Elon Musk does not have the glasses on that time but, before greeting Milei, Musk puts the sunglasses when he warns that they are recording him. Touch the image to go to the original message Elon Musk has already recognized in the past being a ketamine consumer by medical prescription To treat depression. Although an investigation of the WSJ revealed that the erratic behavior that the millionaire has sometimes shown could be due to the cocktail formed For this substance with stressthe insomnia, the Asperger syndrome and the bipolar disorder suffered by Musk. Beyond the medical use of ketamine, Elon Musk has been in favor of the Use of microdosis of hallucinogenic substances. A very widespread practice In the high venture spheres of Silicon Valley.

I have tried Grok 3 and it is really intelligent and fast. The problem is that this is no longer enough

I’ve spent a few hours trying Grok 3the new version of Xai AI. I wanted to see their real abilities and especially how it behaves, what kind of results, in front of Chatgpt, Claude, Le chat, Deepseek… Reasoning and problem solving It stands out in mathematical problems. I made him complete the challenge Aime’24of which he was 6 of the 15 problems, for the 9 hits of OPENAI O3-mini-high. In addition, Grok 3 took a little less than five minutes, but O3-mini-High took almost six. Very striking to see their self -assessments until you find the correct answer (although sometimes it was not). A fragment of the steps that Grok 3 took to evaluate their own conclusions before presenting them as a final result. Image: Xataka with Grok 3. In basic reasoning tests, such as determining the number of repeated letters in somewhat complex words (the classic “lollapalooza”) or comparing decimals (9.11 vs 9.9), Grok 3 responds correctly after a few seconds of visible “thought”. O3-mini-High Be right after 6 seconds. Image: Xataka with chatgpt. Grok 3 also succeeded, but after more than four times longer. Image: Xataka with Grok 3. In a Greek mythology question about Jason’s maternal great-grandfather, Grok 3 found the correct answer in 18 seconds … while O3-mini-High needed 22 seconds to fail. Well played, Grok. O3-mini-High missed. Image: Xataka with chatgpt. Grok 3 instead gave a better built response, in addition to correct. And it takes less. Image: Xataka with Grok 3. Search and synthesis Its function Deepsearch is fast but sometimes it is not entirely precise and does not mention any important detail. I asked to analyze the impact of AI on chips design and, although it generated a text of 1,504 words with several quotes in just over a minute, omitted to mention important advances such as the framework ALPHACHIP from Google. In later and insistent attempts he did. I also asked for a full report on Xataka On financial, media, reputational level, etc. It was quite successful, although it showed an inherent limitation of any Deep Research system: He knows a lot about what is in public, but he doesn’t have many Insightsit lacks the expert criteria that knows not only the public, but what underlies. This is something of Grok and any other with Deep Research. When you ask for information about something you do not control, it is easy to assume that Deep Research (or in this case, Deepsearch) gives you everything. When you are in garlic it is easy to detect deficiencies. As in this example. Image: Xataka with Grok 3. The speed impresses: it is remarkably faster than Deep Research of OpenAi … but at the cost of sacrificing depth for speed. Of course, your selection of sources and appointments is usually really good. Unlike Gemini, it does not allow exporting reports directly to documents or customize the research approach. Again: Grok is very intelligent and capable, in his own way, but he lacks a product. Little llm is of little use if it forces to start from scratch and process all the information. Creativity and tone To try his creative writing I asked him for a story about a time traveler facing a paradox. The result was quite solid in construction of characters, details, descriptions and atmosphere, overcoming even the one that I consider the best in that aspect, Claude 3.5 Sonnet. Of course, some plot turns seem quite forced. Image: Xataka with Grok 3. His humor is basic and predictable, limited almost all the time to quite obvious words games. Teenage humor If the concept of disturbing valley You can move to a chatbot, Grok 3 is in that 99%: too fine to look like a caid robot, too predictable to finish convincing. It maintains political neutrality even on issues such as immigration or trans rights. Musk says it can be politically incorrectbut it seems that it is something that has more to do with what the user requires that a feature of his personality. That is to say: it can be taken out of correction, but only when the user pushes to it. Some limitations It does not allow customizing the behavior of the model, unlike chatgpt; or the response style, as Claude allows. It is limited to being a text drawer. You are only accompanied by the buttons to attach a file, activate your Deepsearch or activate your reasoning mode. That, and a few elementary instructions. No projects such as Claude or GPTS of Chatgpt, or the agents of Le Chat. In short: Nothing to retain pre -established contexts and guidelines or documentation to facilitate work. We always have to start from a new canvas. The interface is good, intuitive, simple … but they miss tools that make it more versatile and appetizing to integrate it into our day to day. It is powerful and capable for specific uses, but the product built around chatgpt, claude or le chat (projects, agents, previous instructions, etc.) make those alternatives something much more interesting for serious and recurring use. Image: Xataka with Grok 3. The security keeps are stricter than those of Grok 2. with that version We hallucinate for its lack of scruplesbut Grok 3 seems to recover them: he refused to generate a template for a mass fraud campaign by mail simulating that I am a Valencian prince in search of heiress. The generation of images does seem, again, more lax. Midjourney does not allow to create anything containing the words “Donald Trump” or “President of the United States”. Nothing. Grok 3 does not put so many objections. Not even with its owner. Image: Xataka with Grok 3. You can try Grok 3 from its official website or from Its integration into x (which is why you have seen two somewhat different interfaces in this article). It is temporarily free, but we already know that it will be one of the reasons to pay a subscription to X, and not the cheap. Its ability … Read more

It is impossible to make it cheaper

I think it threatens the existence of some of these companies. I have no idea what will happen in five years but I know what I see. Things are going to change The words are from Terry Woychowski And he knows well what he’s talking about. Woychowski was a senior executive of General Motors and in recent years he is president of Cassoft Global Technologies, consulting that is responsible for explaining to manufacturers where they have room to save money and how they can do it. His comparisons, of course, are now focused on Chinese cars. How its manufacturers get so much money in the production of their cars and how they position themselves to be a real threat to traditional West producers. Consulting that pass, obviously, by disassembling cars from one and the other and pointing out the differences. Taking out the … shame? To one of those last demonstrations the journalists of Automotive News. “What we see from the Chinese is an existential threat,” Woychowski stressed. Is exactly The same speech Employee by Jim Farley, president of Ford, a few months ago. In Ford they had reached the same conclusion as Cerseoft Global Technologies experts by dismantling some Chinese cars themselves. The strategy is usual, with traditional manufacturers trying to understand what they do in China different from them to lower their vehicles. In fact, This same company already told Toyota that could forget all the way they had so far. Everything learned and applied little by little, with minimal improvements but that added their excellent and reliable vehicles also made them more expensive and prevented them from competing at a price. And something very similar is what they have told US manufacturers. They put as an example the complications they face when manufacturing the ceiling of the vehicles. According to the consultant, the Americans use IMAES WITH RARE EARTH with a dollar cost for each of them. That forces them to use steel next to aluminum to guarantee their fixation. On the contrary, the Chinese use a simple adhesive strip that each one costs each. That is, at least twelve less and a much less complex and faster process. Something similar happens in the dashboard. While Americans use heavy metals after the dashboard, the Chinese or Tesla use plastics with profusion. The same pointed to Toyota, making it clear that, without the vibrations of a combustion engine, this way of working had become obsolete and only the product increased. In addition, from Caseoft they point out that all this competitive advantage has been possible because the State itself has created the China Automotive Technology & Research Center (Catarc)an agency created in 1985 that defines the standards of approval but also provides assistance for the development of new products, including the development of driving aid systems or autonomous systems. They have promoted an industry, they say, intensely competitive aware that some companies will stay along the way. However, this forces them to work faster and find solutions as quickly as possible. A pressure that leads them to use a month to get a new piece that arrives from an external supplier while in the West you need to use nine months. A meeting? Caseoft experts say that arranging an appointment with the person in charge of a supplier does not take less than two months but that in China they barely solve it in a week. If you want to compete in price, manufacturers have to standardize their products more, they say. It is the strategy that was used by the United States government to save costs during and after World War II and is the technique applied by Chinese manufacturers where the truly differential is software.

The United Kingdom has been investigating why there is a giant hole in a street. The problem is that another

At the beginning of February there was such an unusual event in Japan that it was news worldwide. In the north of Tokyo it had appeared a giant hole that “swallowed” a truck and its driver. Worse: every day that passed it became bigger. The story in Asia is not over yet, but in Europe the scene has just been repeated. On Monday, the United Kingdom dawned with a mysterious and giant hole in a street. And then there were two. An unexpected collapse. The story began last Monday night. A huge crater appeared on a very busy street in the town of Godstonein Surrey County, England, growing rapidly until reaching 20 meters long, six meters wide and five meters deep. Shortly after, a second hole of five by five meters and the same depth arose on the other side of the street. Although both have stopped expanding at this time, the magnitude of the sinking has forced to evacuate around 30 homes and has generated serious concerns about the structural safety of the area. The solution goes for long. What the hell is happening. The big question. Although the exact cause is still unconfirmed, Geologists suggest several hypotheses. The region is settled on weakly cemented sandstones dating from the lower Cretaceous period, more than 100 million years ago, an area that It can easily erode with the action of water. In this regard, Pete Burgess, expert from the Wealden Cave and Mines Society, explained that The nineteenth -century maps show an area marked as a “sand quarry”. This quarry would have been exploited for decades to extract sand used in construction and gardening, leaving unstable land. Plus: factors such as heavy rainsexacerbated by climate change, could be further weakening underground structures, causing collapse or collapse. In addition, and as it happened in the case of Tokyoit is possible that a broken pipe has eroded the rocky substrate, or even that the roof of one of those old sand mines has collapsed, triggering the sinking and in turn, damaging a water pipe. That said, what is most repeated among experts is that The growing urbanization in the United Kingdom has increased pressure on infrastructure of sanitation already aged. Impact on the community. Although they have not reported injured, the life of residents if it has been seriously affected. Cases such as Noosh Miri, one of the evacuated people, who declared that His house is no longer safe and does not know when he can return. Traffic, of course, has diverted, and the country’s media speak of a car that was dangerously close to the edge of the second hole, without its owner being able to withdraw it. In addition, some residents have had to Spend the first nights in their vehicles due to uncertainty about the stability of their homes. For all this, Tandridge District Council has enabled an information center to attend those affectedwhile Bletchingley Parish Council has offered its sports hall as Temporary refuge for those who do not have housing insurance. Councilor Linda Baharier stood out The difficulty facing tenants who do not have insurance coverage and must find a long -term housing alternative. A call to the community has even been released so that who have available rooms can host. Economic impact: closure of shops. The economic repercussions of the disaster are also significant. I told the BBC Shane Fryowner of the mechanical workshop DD Services, of his concern about the closure of the road and the restricted access to his business, which has drastically reduced its clientele. “We have lost an important part of our income because people cannot get here or simply choose not to come,” he lamented. With four employees in charge and families that depend on the workshop, Fry anticipates difficult months. Other businesses in the area face the same uncertainty. Graham Bristow, owner of Blossoms Café, told the British chain that his daughter, who manages the business with him, is trying to stay optimistic, but fears that the next months will be devastating. “If we suffer losses, will there be any kind of help, such as tax reductions? We don’t know it,” he said. Measures to repair a giant hole. Local authorities have cataloged the incident as A “major emergency case”. Currently, they are being carried out Structural studies to evaluate security of the area and determine how to fill the craters definitively. The bad news? Than repairs They could take at least months. Meanwhile, some residents have been able to return to their homes to collect essential belongings, although there is still no clear date for their final return. Let’s think that repairs not only involve filling the holes, but completely rebuild the road from the baserelocating and reconnecting all public service pipes and networks before being able to repair. Are these undercuts common? The truth is that sinkings in the United Kingdom They are usually smaller and occur in rural areasalthough occasionally they emerge in urban areas. In December 2023, a sinking in Wales affected the house of a reality winner Love Island. That said, the collapse in Surrey has been particularly striking, and geologists repeat that although Most housing are not built on land of old registered minesin some cases the houses have been built on those undicted medieval mines, which It generates unforeseen risks. In short and As in Tokyothe two undercuts in the United Kingdom have evidenced the vulnerability of certain urban areas to geological and climatic factors. While experts work in solutions and in determining the exact cause of collapse, residents face the uncertainty of an uncertain return to their homes, possibly months. If you want also, the incident stands out The need to review and reinforce infrastructure in areas with sinking potentialespecially in a context of growing urbanization and climatic changes that could aggravate this type of phenomena in the future.

It is a critical milestone to get to nuclear fusion

Imagining a world with clean and inexhaustible energy is no longer just science fiction. France has achieved a unique milestone to maintain a plasma reaction in minutes. An unprecedented advance. On February 12 in France, the West reactor of the Atomic Energy Commission and Alternative Energies (CEA) has managed to maintain a plasma For more than 22 minutes (1,337 seconds), thus beating the previous record of plasma duration reached with a tokamak. This represented an improvement of 25% with respect to the previous record time achieved with EAST, in China, which reached 1,066 seconds (17 minutes) a few weeks before. In addition, the plasma reached a temperature of 50 million degrees Celsius. In depth. This achievement has shown that magnetic confinement technology is moving forward, allowing reactors to sustain the extreme conditions necessary for nuclear fusion for longer periods. The longer the plasma is controlled, the closer we will be generating fusion energy continuously, reliable and commercially viable. To achieve that time and control plasma, the Eurofusion consortium scientists They have applied a combination of strategies, such as temperatures between 100 and 150 million ° C, 2MW injection of thermal power and the use of superconductive coils and cooled components. In addition, the materials were protected, minimizing erosion and contamination of the internal components of the reactor. Why nuclear fusion? Nuclear fusion It is considered the “Holy Grail” of energy because it does not produce long -term radioactive waste, unlike nuclear fission. Besides, Use less resourcesIt has a practically inexhaustible fuel and could generate clean and stable energy without carbon emissions. Magnetic confinement technology in Tokamaks is the most advanced today and is considered the most viable path to obtain merger energy. A global effort. The study of nuclear fusion and seeking its stability is being given in different parts of the world. Starting with ITERthe experimental reactor that an international consortium led by Europe is building in the French town of Cadarache. On the same continent a little higher in Germany and in France themselves are exploring other alternatives such as type reactors Stellarator. Out of the European Union, in the United Kingdom, the JET It was for years the referent in generation of fusion energy, closed in 2023 after providing key data for the development of the future Iter. In Asia, in Japan, the JT-60SA It is a joint project with Europe that seeks to optimize plasma stability. In China, the reactor East It has broken temperature and duration records of the plasma, approaching necessary conditions for commercial fusion. For its part, KstarIn South Korea, he has managed to keep plasma at extreme temperatures for prolonged periods. Forecasts West’s record has shown that magnetic confinement technology in Tokamaks could approach The possibility of building viable commercial reactors. In addition, this progress has shown that the knowledge of the plasmas and the technological control of them for longer periods is maturing and offers the hope that merger plasmas can stabilize for longer periods in machines such as The iter.

Some microbiologists have taken 10 years to solve a problem. The AI ​​has solved it in two days

Professor José R. Penadés and his Imperial College team in London had been working on a way of demonstrating how certain superbacteria are immune to antibiotics. After all that time they had finally achieved a conclusion in this regard. They recently dedicated to give AI a chance to solve the same problem. They got a surprise. Ten years they, 48 hours the AI. The scientists used a new Google AI tool called co-scientist to provide a brief prompt asking him about the essential problem they had been investigating for ten years. The AI ​​reached the same conclusion as them, but it took only 48 hours to reach it. And the AI ​​did not know the response in advance. One of the important details here is that AI could not have found out the solution looking for it on the Internet. Penadés and her team had not published the study, so Co-Scientist could not find the answer because it was not public domain. “I need to digest it”. The Penadés Professor He indicated in BBC How he learned that AI had reached the same conclusion in just two days. “I was shopping with someone, and I said,” Please leave me only one hour, I need to digest this. ” no. I could have saved years. Even considering the AI ​​solution as a hypothesis when they started working on the problem, having it would have saved years of work, Penadés explained. But it was the AI ​​went further. In fact, Google tool had done more than replicating its research. “It was not only that the hypothesis he provided was correct. He provided another four, and all of them made sense. And in one of the cases, he never occurred to us, and now we are working on it.” A for superbacteria. The study tried to reveal how some superbacteria are created that are resistant to antibiotics. The hypothesis proposed that superbacterial can form a tail from different viruses, and that allows them to spread between species. It is as if they had the “keys” to move from one place to another and “enter” different guests. That is the same hypothesis that Co-Scientist arrived in 48 hours. “This will change science”. For the Penadés professor “this will change science, sure.” Tools like this, says, “give the opportunity to play a great game. I feel as if I was finally playing a Champions League match with this.” And there I don’t know the thing: Evo 2 arrives. This discovery binds to launch these days of Evo 2the most large biology -oriented model so far. A group of researchers from the universities of Berkeley, Stanford, the ARC Institute, the UCSF and NVIDIA have trained an AI model with 9.3 billion nucleotides (from which DNA chains are created) from 128,000 Complete genomes. Thanks to this model it is possible to precisely predict all types of genetic mutations. Image | Wikimedia In Xataka | Some engineers have simulated 500 million years of evolution with an AI. Now we have a fluorescent protein
