The US is obsessed with achieving General Artificial Intelligence before China. China couldn’t care less

The promise of the AGI has become the “the wolf is coming” from some AI companies. The gurus of American AI companies do not stop hype with the long-awaited general artificial intelligencethe one that will surpass humans in all areas of knowledge. Meanwhile, In China it doesn’t seem to matter too much. The AGI gap. Elon Musk, Dario Amodei, Sam Altman…everyone agrees that the AGI is about to fall, or so they have said at some point. We cannot know how close they are, what we do know is that to achieve AGI they need more computing power, for which they need a lot (more) money. The AGI as a justification for an insane investment. They count in High Capacity that China barely mentions AGI in its 2025 AI+ initiative nor did it mention it in the ‘Next Generation AI Development Plan’ 2018. AI is a strategic technology of great importance, but they focus on specific applications such as industrial automation, autonomous driving or robotics. Transformative, yes, but not turning points that will change the world completely. Whoever arrives first wins (or not). It’s American logic in this race. To achieve this, they are betting everything on one horse and AGI is the goal. If they arrive before, they will obtain an insurmountable economic and military advantage: they will have won. On the other hand, if China arrives before, the power relationship would change completely. The truth is that things have to go a lot wrong for the US to not win this race. The problem is that, while they are making this titanic effort, China is beating them on other fronts such as the electric car, industrial robotics, drones, solar panels… Win the AI ​​battle, but lose the economic war. China is calm. Why aren’t China so excited about AGI? To begin with, it is not so clear that scaling the models is the fastest route to AGI and that requires a gigantic investment with no guarantees. But above all it is because they do not buy the idea of ​​”arriving first”; Even if the US overtakes them, they can simply copy them and catch up quickly. Yao Shunyu said itchief AI scientist at Tencent: “History shows that once a technical pathway is validated, Chinese teams can quickly replicate it and even surpass it in specific areas, such as electric vehicles or manufacturing.” The question is not so much who gets there first, but who makes the best use of it. Who does talk about AGI in China. Yao Shunyu’s statements occurred within the framework of the AGI-Next Summit, where several leaders of Chinese AI companies met to talk about the future of the sector. Figures such as the founder of DeepSeek, the CEO of Ziphu or the founder of Moonshot have talked about their goal being to achieve AGI, although they have not shared many more details. Maybe the company that Alibaba has gone deeperwhich gave a presentation detailing its plans to achieve superintelligence (ASI). These leaders, like those of American companies, may have commercial motivations in these statements, but there are other organizations in China that are investigating this field such as the Beijing Institute for General Artificial Intelligence or the Chongqing Institute for General AI. There are initiatives, but there is nowhere near the level of obsession that they have in the US. A restful strategy. While the US hoards chips and scales like crazy, in China they are choosing to do it more slowly. They are prioritizing national chips and open source with the idea of ​​promoting the adoption of their models. It is a more long-term vision. A long distance race, not a sprint.

In 1978 Christopher Reeve was chosen to play ‘Superman’. He got so beaten up that he literally couldn’t fit into the suit.

In the mid-seventies, superman He wasn’t just a character: he was DC’s goose that laid the golden eggs and a bet that could make or sink the first great modern superhero blockbuster. Producers Alexander and Ilya Salkind wanted a “serious” and grandiose film, far from the tone camp from the sixties Batmanbut they also knew that any setback would be a historic embarrassment. Too big to fail. In that scenario, DC, suspicious, imposed conditions of the strictest and he monitored the project as if it were a surgical operation, because the underlying problem was not to make a film: it was to make it with a guy in tights and a red cape and get the public to I will look at him with respectnot like a meme. Two years of casting. Thus, the search for superman perfect became the great bottleneck: it began in 1975 and continued until February 1977with hundreds of tests and a growing sense of desperation. There was, as usually happens in any great production, a star wish list that seemed more a festival poster than an audition: Robert Redford, Paul Newman, Warren Beatty, Clint Eastwood, Steve McQueen, Burt Reynolds, Charles Bronson, James Caan, or even Nick Nolte. In fact, there were many more, in addition to proposals that today they sound delirious by pure marketing logic, as think of Muhammad Ali or even in people outside of interpretation. It turns out that each option failed for something (if it wasn’t cost, it was age, image, accent or fit in general) and the message was clear: without Superman, there was no movie. The definitive twist. In the midst of that chaos, Christopher Reeve arrived from the New York theater as an answer that did not fit the cliché of the “big name” that the producers were looking for, but did fit the essence of the character. The casting director was pushing his candidacy against the team’s inertia, until he was finally given a real opportunity. When Richard Donner, the film’s director, saw it, the trial was as clear as it is uncomfortable: Reeve had the height, the face and the aura to be Superman… but he was also too young and too thin (“a stick”were the director’s words) to fill a suit that required visible strength, not just presence. Even so, in that test (between nerves, the heat of the spotlight and a still ungainly appearance) something that no one could copy became evident: the potential to make Clark Kent and Superman credible in the same person. The actor before opting for his role in Superman Stop being a “stick”. Reeve got the role with an unspoken demand which was actually an ultimatum: he had to physically become Superman, and do it quickly. The producers even suggested use fake muscles under the suit to “trick” the camera, a typical solution in the cinema of the time, but he refused, because he understood that credibility was not built with filler, but with transformation. The movie needed the body to say “superhero” before the character even spoke, and Reeve assumed that the job was not just to act well, but to look impossible without falling into excess. Darth Vader as trainer. Here comes the anecdote that seems invented by an advertising department: the man inside the Darth Vader suit, David Prowse, also a bodybuilder and instructor, was the one who was in charge of sculpting to Superman. Donner called it like someone activating a emergency plan: “we have a Superman” and we have to build him against the clock. Prowse trained Reeve for weeks with a routine focused on gain mass and functional strengthsolid enough to withstand flight harnesses, exhausting days and the symbolic weight of the character. And in the process a perfect story was born to sell the film: the most intimidating physical villain of the moment molding the definitive hero of the decade. The “obsessive” transformation. The method was so simple as brutal: eat a lot, train thoroughly and not allow yourself to lose weight even for a single day. Reeve put himself on a high-protein diet, with four meals a day, shakes and vitamins, and with an almost paranoid discipline: skipping a meal meant going backwards, and going back was a disaster. The idea he repeated was very clear: the actor’s inner work is useless if the exterior does not support the fantasy, because Superman cannot “seem” weak, even if he is vulnerable on the inside. And the most interesting thing is that that physical strength also changed him. the psychology of paper: The stronger he became, the more natural the character’s calm authority came to him. Too “handsome”. The result was so extremely effective that it became a continuity problem: Reeve continued to gain muscle during filming and there came a point where It was not the same body of the first scenes. The production had to redo shots already filmed because the superman of one day did not fit with the Superman of weeks later, and the suit, designed for a “before”, began to behave like a shell that was too small. The ironic twist is that at first they wanted to put fake muscles under the uniform and, after the transformation, the opposite happened: They were able to remove the additions to the suit because they were no longer needed, and the film was left with what it had always needed from the beginning, a Superman with real muscle, without tricks or cardboard. The myth that remained. Over time, Reeve’s physique has been compared with the hypertrophied standards of today’s superheroes, but at the time it was quite an event: his change from “tall, skinny actor” to muscular icon It was part of Superman’s own story even before of the premiere. The important thing was not to compete with modern mountains of biceps, but to build an exact illusion: that this guy could be the most powerful on the planet and yet the most human when he looked at Lois … Read more

If you thought that getting the DGT V-16 beacon right couldn’t be more complicated, the beacons with an expiration date have arrived.

Buying an approved and fully valid connected V-16 beacon is relatively simple. Or, at least, it should be. Because to the list of products and companies that market a completely valid product are added the beacons that can continue to be sold… but that will no longer be able to be sold. Yes, the DGT has opened a new list… and now everything is more confusing. The approved V-16 beacons. So that a V-16 beacon is valid by the DGT and is completely approved, the product must meet a series of requirements. Among the most important are the following: Connectivity with DGT 3.0 for at least 12 years Radiate light 360 degrees Maintain irradiation intensity for at least 30 minutes Protection degree IP54 at least Guaranteed operation between -10ºC and 50ºC How do I check it? It must be taken into account that non-approved beacons are being sold on the market despite being completely legal… more or less. And when the arrival of the beacons was approved in 2021, we didn’t know anything about the DGT 3.0 platform. In 2023 it was confirmed that its connectivity with the platform would be mandatory but, by then, beacons without connectivity had already been sold. Right now, they are still on the market selling. These beacons are not valid. We can use them but the DGT will force us to have one approved. From FACUA they point out that there are beacons that are being sold with the DGT badge but that are not approved because they do not have connectivity. Despite everything, they are still on the market. In this situation, the only thing we can do is check if the purchased product is in this list offered by the DGT. It includes each and every one of the products that can be purchased that meets the minimum requirements. The new list of the DGT. Click on the image to go to the official website. Brands and models with certificates with expired validity. Everything seemed, therefore, hands or less clear when it came to purchasing a connected V-16 beacon of those that will be mandatory from January 1, 2026. Until the DGT has added a new list with the name indicated at the beginning of this paragraph: Brands and models with certificates with expired validity. In the description of the DGT to explain what these models are, why they are on this list and what it means, Traffic points out the following: This table shows the brands and models with expired certificates that covered their manufacture and are valid for use by drivers who have purchased them until the end of their useful life. At the time of writing these lines there are three products from the Ledel Solutions CO brand. LTD and another from Ditraimon SL All of them have an end of validity date of 2025. What does this mean? To try to clarify the matter, we have contacted the DGT who have told us the following: “They are beacons that met the requirements in the first approval, but when they went to renew the certificate and had to pass the tests again, they did not meet the required quality criteria” That is, we are talking about companies that have put a valid product on the market. That product, over time, has to pass quality tests again to certify that it continues to meet the minimum required criteria. It was in this second test that they failed and, therefore, lost the certificate that allows them to sell connected V-16 beacons unless they again present a pilot product that guarantees its validity. What if I have one of these beacons? The DGT has confirmed to us that there is no problem. From Traffic they point out that if we have bought or, right now, we buy any of these connected V-16 beacons that are on the market There is no problem because the production runs that have been made until the certificates were withdrawn are completely valid. In theory, we have a guaranteed 12 years of connected V-16 beacon from the moment of purchase, as required by the technical requirements to approve this product. More confusion and more questions. Of course, what is certain is that this new DGT list adds even more confusion to the consumer. And based on the description and the responses from Traffic, it is understandable that a customer may doubt whether their connected V-16 beacon is now valid or not. According to the DGT, we repeat, yes it is. Other questions also arise. If the companies and products that appear in this list as of December 26, 2025 were lost between the months of April and September, why has it not been published until now that they have lost the certificate? In theory and with the answers that Traffic has given us, the companies Ledel Solutions and Ditraimon have not been able to put on the market a new productive run of connected V-16 beacons once the date on which the certificate renewal has been denied has passed, but there is no problem in purchasing one of these products after this date if they were already on the market. Theoretically, they are guaranteed to operate for the required minimum 12 years.

For the first time in history there are mosquitoes in Iceland. And it was assumed that they couldn’t get there

Iceland is being invaded. Not just for touristsbut because of something perhaps more undesirable: insects that had never been seen on the island. For the first time in their history, at least since records have been kept, Icelanders have encountered one of the bugs most undesirable and hated for all of us who have to sleep with the windows open in summer: mosquitoes. They have been few, but they can represent the advance of a full-fledged colonization. Unwanted guests. Bjorn Hjaltason is an amateur entomologist who was hunting for insects last week when he found something strange. On the wine-soaked rope he uses to catch moths and being able to observe it, three insects fell that have nothing to do with moths. They were mosquitoes, specifically two females and a male, but at first, Hjaltason described them as “some strange flies.” And as they count in BBCthe event was such that the local media opened with the news. Because yes, it is more serious than it may seem (and not because of the bites). Shelter. Iceland has remained one of the world’s mosquito-free bastions, one of only two mosquito-free havens. The other is Antarctica, and the reason is that these insects they don’t handle the cold well. Being cold-blooded, they need environmental heat to carry out their activity. When air temperatures are around 10º, their metabolism slows down so much that they become dysfunctional. Not only can they not fly, but they also cannot reproduce. In warmer climates, this is the time when they enter a kind of hibernation, looking for shelters in which to weather the storm until the heat returns. In Iceland it was not necessary because the average temperature was below 10º. BUT. Climate changethere is no more. Records from the Reykjavík observatory show that in the last 30 years there has been a gradual increase of temperatures, with average values ​​that have past from 2.4º to 4.1º. The average temperature has increased by 0.5º in the last decade, almost double of the planet average and there are areas that have broken all records. They are also occurring extreme episodeslike the 26.6º that in Córdoba would be pleasant and to go out with a jacket in the morning, but that in May of this year must have felt like real hell in Egilsstaoir. There were episodes like this before, but reports indicate that these events that were anomalies are becoming more common. You have to wait. Mosquitoes, of course, are at ease with those temperatures, but the big question is where they came from. Hjaltason found them in Kjós and speculates that they may have come on a freighter that landed at Grundartangi. The two cities are in western Iceland and the insect enthusiast points out that unusual ‘bugs’ usually come in those freighters. Another entomologist, Matthías Alfreodsson, to whom Hjaltason sent the mosquitoes confirmed that, although they belonged to a species that tolerates low temperatures somewhat better –Culiseta annulata-, they should not be in Iceland and we will have to wait until spring to check if the species has really established itself on the island. But Hjaltason is clear that if three of them went directly to his garden, “there will probably be more.” I feel sorry for you, fellow Icelanders.

We thought we had solved the mystery of the giant “trees” of the Paleozoic. We couldn’t be more wrong

More than a century ago, when the first known fossils of Prototaxitesintuition said that it should be the remains of a tree. Decades of study revealed to paleontologists that this fossil did not belong to a plant, so everything seemed to indicate that it was an immense fungus. Now a new study has reopened this unknown. Neither plant nor fungus. The study in question has revived the discussion About the nature and taxonomy of Prototaxitesprehistoric beings that so far the catalog scientific consensus as fungi. The involvement of “taking out” these beings from the evolutionary branch of fungi is that perhaps these beings belonged to an extinct and unknown branch of the tree of evolution. 400 million years ago. What we do know about Prototaxites For the fossil registry, it is that being trafficking with organisms that were alive towards the middle of the Paleozoic era, does Between 420 million and 375 million years. These beings had a more or less cylindrical structure, similar to a trunk and stood up to eight meters above the sky with a diameter that the subway could reach. These measures and their age make them one of the first large beings of those of which we have record in the fossil registry. The debate on the nature of these prehistoric living beings seemed to mid -2000s. It was then that an analysis revealed that the Prototaxites They did not obtain their carbon from photosynthesis, as is the case of plants, but obtained from other living organisms, as fungi do. Rhynie Chert. The new study that reopens the case It now contributes tests that this being did not belong to the kingdom of fungi and focuses on one of the known species of this genus, Taiti prototaxites. The team resorted to the fossils found at the Rhynie Chert site in Scotland. This site contains not only fossil remains of this species, but also of fungal species and others belonging to other kingdoms of nature. Similarities and differences. The new analysis of the fossils of this species ran into some similarities with fungal structures such as those that could be expected. However, despite having tubular internal structures similar to those of fungi, these tubes in P. Taiti They branched and linked in a different way from what they could expect. That was not, however the strangest detail. The analysis did not detect in fossils evidence of the products that are associated with the presence of chitina, a compound present in the cell walls of all contemporary fungi and that we know was also present in prehistoric fungi. They found that the chemical “firm” was more similar to that left behind by lignin, a polymer that we associate with vascular plants. The study has been published for now draft In the repository Biorxivso the standardized scrutiny of peer review has not yet passed. So what? This detail implies that we must extreme caution when drawing conclusions from the study we have in front. Even so, the signing team of the study outlines in this its conclusions, in principle preliminary. In his study, the team concludes that “the morphology and the molecular footprint of P. Taiti It is clearly different from that of fungi and other organisms preserved with it in Rhynie Chert, and we suggest that it is better considered a member of a group not described and totally extinct of eukaryotes. ” In Xataka | An amateur fossil search engine is behind a curious finding: vomiting of the dinosaurs era Image | Іщн

Sabalenka couldn’t beat Madison Keys

The American Madison Keys destroyed all predictions at the Australian Open. It was not enough for her to overcome a match point in the semi-finals against the No. 2, the Polish Iga Swiatek. She completed her masterpiece by overthrowing the two-time champion and world No. 1, the Belarusian Aryna Sabalenka, 6-3, 2-6 and 7-5 in 2h.02′. At 29 years old, eight after losing the final of the 2017 US Open to her compatriot Sloane Stephens, she experienced her moment of glory in world tennis. Recently married to former player Bjorn Fratangelo, since the party in November everything has been happiness for pupil and coach. They have won 13 of their 14 games, they have won the last eleven. She was able to beat the one who was called to be queen for the third consecutive time. Sabalenka was left without a hat trick, as she destroyed her racket once she completed her defeat. Madison Keys stronger in the end Keys coped well with the agony of a final full of emotions. Sabalenka was far from being the player who overwhelmed Badosa. Strangely, in her fourth Grand Slam final, she seemed more nervous than ever. Keys laughed and cried because she did not expect a better gift at Melbourne Park, adorned with her return to the world top-10: on Monday she will rise from fourteenth to seventh position. She has worked on it with great dedication and enthusiasm, believing in herself. Only with faith and tennis could Sabalenka be dethroned, who had 20 consecutive victories in Grand Slam and at the Australian Open, who was knocked out after eleven consecutive victories on the court. Keys’ performance was unexpected, overcoming the reaction in the second set of a rival without the inspiration of other days, too anxious. The world turned upside down, the champion of four Grand Slams suffered more than the one who is now making her debut, taking over from Sofia Kenin, the previous American winner in this Open, in 2020 at the expense of Garbiñe Muguruza. Historic first Grand Slam At 29 years of age, the tennis player from Illinois (United States) became the fourth oldest player to win her first Grand Slam title, behind the Italian Flavia Pennetta (US Open at 33 years old), the British Ann Jones ( Wimbledon at 30 years old) and the transalpine Francesca Schiavone (Roland Garros at 29 years old). This was Keys’ tenth title in his professional history, having previously lifted the trophies at Eastbourne in 2014 and 2023, Birmingham 2016, Stanford 2017, Charleston and Cincinnati 2019, Adelaide II in 2022, Strasbourg 2024 and also Adelaide in early this year, a contest that preceded this great achievement in his career. Before her conquest, 15 other North American tennis players had managed to win the Oceanic Grand Slam: Dorothy Bundi (1938), Doris Hart (1949), Louise Brough (1950), Maureen Connolly (1953), Shirley Fry (1957), Nancy Richey (1967), Billie Jean King (1968), Barbara Jordan (1979), Martina Navratilova (1981, 1983 and 1985), Christ Evert (1982 and 1984), Monica Seles (1996), Lindsay Davenport (2000), Jennifer Capriati (2001 and 2002), Serena Williams (2003, 2005, 2007, 2009, 2010, 2015 and 2017) and Sofia Kenin (2020). The greatest exponent of the Australian Open continues to be the local Margaret Smith, who won 11 titles from 1060 to 1973.
