Steve Jobs and Bill Gates seemed irreconcilable enemies. They were actually great allies: “We worked well together”

by

In the field of technology, times of A fierce rivalry between large companies to master a certain market: Intel and AMD, Sony and Nintendo, Nvidia and AMD or, of course, Apple and Microsoftwith Steve Jobs and Bill Gates as representatives of that rivalry. However, beyond that business competitiveness to achieve The best products of the market with PC or Mac: Bill Gates and Steve Jobs cultivated a relationship of “intimate enemies” based on mutual respect and recognition. Complementary adversaries Microsoft and Apple’s story has been marked by rivalrybut on many occasions, both companies have collaborated hand in hand to develop products. However, despite those collaborations that, for example, took Office to the Macintosh, has maintained the image of Steve Jobs and Bill Gates as eternal irreconcilable rivals. Nothing is further from reality. In An interview For the podcast ON PURPOUS From Jay Shetty, Bill Gates confessed that Jobs and he were complementary, and that allowed them to work together on different projects. “I had a fantastic relationship with Steve. At first I worked with Jobs and Wozniak with Basic for Apple 2, and later, as Steve had a small group inside Apple developing the Macintoshinvited Microsoft to make some software applications for him. We work very closely in that project. We loved both of the result and ended up being a key product for Apple, “Gates explained. The founder of Microsoft stressed that “although we were very competitive, we also admired each other.” Apparently, Steve Jobs thought the same as Bill Gates. In one historical interview in which journalists of The Wall Street Journal Kara Swisher and Walt Mossberg sat on both on the stage of conference D5, Steve Jobs claimed citing the song Two of the Beatles: “‘You and I have longer memories than the path that extends ahead’ and that is clearly true in this case.” Gates assured that the secret of the long relationship of love/hate between Apple’s co -founder and he was that both were complementary. “We worked well together. He was very good in what I was not,” said the millionaire. Without Apple and Microsoft the computer science would be different The visions of how a Microsoft and Apple computer should be They were very differentand a faithful reflection of the strengths of their two leaders. While Apple put all the focus on design and efficiency, in Microsoft they focused on developing a platform for their software with the aim of taking a computer to each house. “They said we were out of reality, but we knew that computer science would be part of everyday life,” Gates recalled in his interview. “Steve had incredible skills. He appreciated the user design and interface and even for his intuition with people. It was simply a genius in a way that I cannot explain. I did not look at the code or write it. Instead, the programming is mine. Let’s make that faster and more efficient code.” This rivalry and concept differences caused computer science to advance to the mature industry that is currently, with two companies reaching capitalizations that range The 3 billion dollars. This success would probably have been impossible Without the incentive of the competition which was lived in the late 90s and early 2000s. Microsoft’s co -founder millionaire recognized that both had speeches about how computers would change education and improve it, although he also acknowledged that projects to improve the use of computers They were not always successful. “I think we were both satisfied with what we had done. We got a seat in the front row and helped build all this,” Gates said in reference to the last conversations he had with Steve Jobs before his death in 2011. In the joint intervention that both founders made in 2007, Steve Jobs defined how he saw the competition between Apple and Microsoft of the late 90s: “Many people believed that the rivalry between Apple and Microsoft was a zero -sum game in which for Apple Microsoft won had to lose. It was clear that it was not necessary to play that game because Apple was not going to beat Microsoft. Microsoft. In Xataka | Elon Musk got outstanding in computer science.

The arrival of the human being to South America, seen through the DNA of the heirs of the last great migration

by

Throughout our history as a species, Homo sapiens We have managed to reach the most remote corners on Earth. Millennia before the era of exploration, our ancestors undertook a trip that took them out of Africa and populate the great continental masses from Europe to South America. Among all these great migrations, one of the most surprising was the one that led humans from Siberia to Patagonia, a 10,000 trip whose details are knowing. History in genes. A new genetic study has given us new clues on the great migration that resulted in the population of the Americas. A migration of 20,000 kilometers whose implications still last in aspects as apparently distant as health. The study allowed to draw the history of migrations until the considered “final border” of human migrations, Tierra del Fuego, Explain the team responsible for the study. History of a millennia trip. This great migration would have begun in Siberia between 27,000 and 19,000 years ago Approximately during the last glaciation, in what we know today as the Bering Strait would have formed a “bridge” of land due to a lower sea level than the present. Through Alaska, these populations would have arrived in North America, but the expansion through this continent would have been only an intermediate stage. The study focuses on the second part of the trip, when part of the new American population crossed the Central American Isthmus to enter the last continent in being populated. The last border. The new genetic analysis allows us to know how humans expanded in South America. The responsible team detected that lineages In this continent they began to diverge with each other between 14,000 and 10,000 years ago. From this point, the South American population began to separate into four groups. The first to disintegrate was those who populated the Amazon basin, while the rest was distributed among the high areas of the Andes mountain range, the desert area of ​​the Chaco, and finally, Patagonia. Reading migration in genes. For its study, the team sequenced the genomes of 1,537 individuals belonging to 139 villages of the continent. The details of the study were published In an article In the magazine Science. Very long -term implications. The consequences of this migratory movement and its vicissitudes still last and some of them still weigh on the native peoples of South America, especially as a consequence of the isolation of some of these populations with respect to the rest of humanity. This could explain why some populations were more susceptible to the introduction of infectious diseases by the first Europeans to reach the continent. “Those migrants carried only a subset of the genetic heritage in their ancestral populations (…). Thus, reduced genetic diversity also caused a reduced diversity in immunity -related genes, which can limit flexibility when fighting several infectious diseases,” stood out in a press release Kim Hie Lim, Co -author of the study. From the past to the present. Knowing new data on the genetics of American peoples can also help us in the present. This information is valuable when studying treatments of genetic diseases, or to better understand the functioning and impact of certain medications. In addition, the closest relationship between American and Asian populations implies new data on a population that, recalls the team responsible for the new work, covers 50% of the world’s population.

The owner of a Tesla Model and set out to come to Everest with his electric car. And he had a great idea called gasoline

by

There is an obvious reason that continues to wear the sale of electric cars in Spain: the alleged lack of loaders. In Xataka We have already tried that it is not so much a lack of loaders as a evident invisibility of them and one lack of trust in your reliabilitywhich causes doubts that they have thought or might think of making the leap. On our trip From Berlin to Madrid aboard a Tesla Model 3 We verify that Europe is very nourished by chargers of all kinds, from rapids that allow recharging while you eat to the slow ones to use while you make night, passing through the ultra -graphs that on the service roads put the car in tune in a few minutes. But, as much as we want, we talk about Europe and not all places have the same facilities. You just have to look at the United States where recharge network It is much more scarce and unreliable than in our continent, which is delaying the adoption of technology. So, can we travel anywhere in the world with an electric car? Could we match the trip that this influencer is making for Carry your Fiat Marea to Japan from Spain? Could we, for example, go to Everest by electric car? Common sense tells us no. But it’s just that, common sense. A tesla, a generator and the roof of the world Common sense, beyond the manida phrase that it is the least common of the senses, is also fluctuating. What for some may seem an impossible mission, for others, simply, it is as easy as taking appropriate measures and adapting to each situation. That is why the owner of a Tesla Moder and did not see any problem in taking his car and putting Rumbo to Everest. If on the road I could find the electricity assortment, it was the least, it would manufacture it. As? Obviously, with an electric generator moved by gasoline. The story is told in Carnewschina where it is explained that the owner of the electric car created its own version of “extended autonomy.” To do this, he installed an 8 kW gasoline generator at the rear of the car. With him underway, he could fill the Tesla Model battery and a power similar to that of a domestic plug, specifically 3 kW. In the middle they point out that at that rate The Tesla recovered 19 kilometers Of autonomy every hour and that, full of the tank, the cargo of the car could be sustained for nine and a half hours. That is, at full capacity the generator could deliver about 180 kilometers of autonomy to the car during, for example, a plugged night. Only in this way has Lhatse County, Tibet region very close to Everest that is already 5,300 meters high. The adventure and its result can be seen in this video where the car owner tells his experience and shows how the system works. Although it is understood why this can be called Tesla Model and a “extended range” car or “extended autonomy”, we must bear in mind that it does not work as a vehicle that implements this technology to use. Simply use the electricity generator as a mobile plug that has to be fed by a fossil fuel. An extended rank electric car is one that is mostly used as an electric and takes advantage of gasoline in a very punctual way. This works, for example, a Mazda MX-30. In this case, it is the car itself that functions as an electricity generating station. The gasoline engine generates electricity that is sent to the battery and nourishes the electric motors that are the ones that move the car. When operating in a concrete regime of revolutions per minute, the gasoline engine always works in its most efficient range and, such as electric motors that move the wheels, although the combustion engine is in operation the touch of the car is still very similar to that of an electric. These types of cars are widely used in China because extended rank electric are considered New energy vehicles (NEV) and are classified at the same level as electric cars even though, in the background, it is plug -in hybrids and can emit CO2 and any other contaminating particle typical of a gasoline engine. In Spain, these cars also have zero dgt emissions sticker as electric since their autonomy is greater than 45 kilometers. But, in addition, they can receive the same aids as MOVES III PLAN that an electric car as long as they exceed 90 km of completely electric autonomy.

Everyone thinks that the Great Guiza Pyramid in Egypt has four sides. From space you look very different

by

A team of Japan researchers scanned under the sand surface in a “blank area” of Giza’s western cemetery next to the Great Keops pyramid. Had found something surprising: an old Egyptian structure in underground. That finding is still involved in the mystery, because it was dwarfed with Another study that he had discovered something fascinating: the great Guiza pyramid does not have four sides, and that explained His longevity. A wonder with trick. For millennia, the Great Guiza Pyramid It has been celebrated as the epitome of the perfect geometry: four imposing triangular faces converging in a majestic apex. However, an unsuspected structural detail had remained hidden with the naked eye: the pyramid It does not have four sides, but eight. Chronology. We are not crazy. The revelationconfirmed by air observations and Modern researchpoints to a concavity in the center of each face, one that is invisible from land, but detectable low certain conditions of lighting or from the sky/space. The first to realize something was the British pilot P. Groves In 1926, when captured an image Air that revealed a subtle but decisive geometric truth. Each of the four apparent sides of the pyramid has a central cleft from the base to the cusp, which turns its plant into a figure eight sidesNot in a home run. Already in 1940, the Egyptologist Flinders Petrieby analyzing historical illustrations, he noticed A hollow line along each face of the pyramid. Decades later, experts like IES Edwards And more recently the Mathematician Akio Kato They supported this hypothesis in their work, noting that the stone blocks were arranged with a Mild inclination towards the center, creating a subtle and almost imperceptible longitudinal depression. Kato described the great pyramid not as a square pyramid, but as a Concava octagonal pyramid. One of the first images where depression was appreciated (taken by groves) An engineering feat. The curious thing about history is that, far from being an aesthetic anomaly, these clefts aim to fulfill a Structural function vital. According to Kato’s study, the inclined layers next to a reinforced base allow the pyramid nucleus to Compacte and strengthen Over time, thus resisting gravitational compression, earthquakes and storms, even after having faced more than 500 episodes of heavy rains in 4,500 years. In other words: this characteristic would have been key to ensuring the long -term stability of a colossal size structure exposed to extreme conditions, and possibly was not a mere side effect of construction, but a sophisticated architectural strategy. Between intention and accident. However, not everything in the Great Pyramid responds to the master plan of an infallible civilization. Throughout their runners and sealed cameras, abandoned spaces have been found that could Unstable result During construction, which leaves open the possibility that the unique concavity has been, in part, the result of improvised adjustments rather than a completely premeditated design. No doubt, ambiguity does not remain merit to the ancient builders, but underline their pragmatism: modify the course when the conditions demanded it, and incorporate the accidental as part of the lasting structure. What the geometry hides. In short, that its mathematical truth has remained hidden with the naked eye for millennia highlights an essential lesson on The great pyramid: Secrets continues to reveal despite his universal fame. What seemed to be an elementary geometric figure becomes, under a new look from the air, a sample of invisible complexity, and technical decisions so advanced that today they still baffle us. The revelation of your Concava octagonal form Not only challenges our preconceived notions, but reaffirms the fascination that always accompanies Guiza, a pyramid that, as far as we know (and we do not rule out new surprises), is a unique geometric rarity in its species.

The autonomous driving was the great absent in the presentation of the Xiaomi Yu7 and there is a reason: the Chinese government

by

May 22 will be a day for the particular story of Xiaomi as a brand. Taking advantage of its fifteenth anniversary, the company celebrated an event in which He made various ads But, above all, he emphasized two new products: an own chip and its second electric car, the Xioami Yu7. The presentation of Second Xiaomi electric car And his first SUV had everything we expected. The force deployment was total. The company confirmed that a year after launching its first car to the market, almost 300,000 vehicles have already put on the street. He was followed by a presentation where there were no single detail to comment. Luxurious details such as several -layer paintings, retractable shooters at the doors (which close themselves), seats designed to rest in them and, of course, an arsenal of comparisons with Tesla, Porsche and Mercedes, whom they point out as great rivals. The other great afternoon star was the Hypervision Hud, a Head-Up Display that crosses all the width of the windshield to project all kinds of information on it, segmenting this in areas and launching the most relevant for each of the passengers. A solution that BMW advanced two years ago but that has not yet put into practice. We had everything in a presentation of the car that spread for almost an hour. Of everything? Almost, almost everything. Because we had a great absent: autonomous driving. No traces of autonomous driving During the presentation of Xiaomi Su7the Chinese company emphasized the autonomous driving capabilities of its vehicles. Showed in a video How the car moved but also how the driver got off the vehicle before entering a parking lot and, autonomously, the car moved through an environment of several plants and parked in a really adjusted space. The commitment to this facet was such that The first time that officially He saw the vehicle in motion was doing it for himself. In recent years, automated driving has been one of the big game boards where the battle for the electric car in China develops. In fact, the company’s rivals have also emphasized it in recent years. Nio has based on its strategy In this area and Byd hit the table recently announcing that His “eye of God” will reach all carsregardless of its price. It was undoubtedly a dart to Tesla who was has worked hard to operate as a vehicle with autonomous driving capabilities. So why was it overlooked at the presentation of the Xiaomi Yu7? During the same, the little that was said about this type of functions is that the car will have A new chipset that will help you better visualize obstacles or pedestrians. And that’s it. The message in relation to security was on the other hand. The company focused on the good results of its chassis and The presentation of a new framework of the cabin, highlighting the materials with which he was made and the pressures he can bear. Why did they spend so much talking about something so technical? Lei Jun presenting the structure of the Xiaomi Yu7 Well, a few weeks ago Three people died aboard an Xiaomi Su7. And there is a suspicion that is floating in the air: they had active the most advanced functions of driving. A fatal accident is something that all brands that want to delve into this market have passed but the Chinese government has given an order: there is no talk of autonomous driving. The companions of Xiaomi world that from The fateful accident There is a generalized concern in the country. So much so that from the government of the country they have launched a new regulation and have given an important notice to the manufacturers, as it has been able to know Reuters. The new regulations will force the possible improvements in the ADAS of driving aid systems to pass an exam. Only after overcoming it can be updated in the cars via Ota. Previously this previous step was not necessary before putting cars up to date. The notice is hard: those who announce autonomous driving functions that cannot be fulfilled may be punished with a fine that will multiply between five and ten times the rate price of the publicized vehicle. This has caused Xiaomi no longer to talk about autonomous driving and assisted driving. Driving aids are a controversial theme in China but also in the West. In fact, in the United States organisms have stressed that terms such as Full self driving and Autopilot of Tesla They point to promises that at this time cannot fulfill. But the company is not the only one indicated, the Drive Pilot Mercedes has also been qualified as such. For now, there are hardly traditional manufacturers that can offer completely autonomous driving systems with open traffic. Level 2 and 2+ systems still require driver’s attention. Even Fordwhich offers a system to travel without hands and without feet also forces this. Mercedes does offer it But in very specific places, with good weather and up to 60 km/h.

In 1999, a manga predicted that Japan would suffer a great cataclysm in 2025. And now there are tourists canceling their trips

by

Samantha Tang is a yoga teacher, is 34 years old, resides in Hong Kong and is in love with Japan. So much so that since the Pandemia ended, he tries to visit the country once a year. Until recently, August was planned on the beaches of Wakayama80 km from Osaka. “I had,” in the past. Despite his passion for Japanese culture, Tang has recognized the CNN that he will postpone his plans for a peculiar reason: “Everyone talks about an earthquake.” Your case is not unique. Japan has found that a surprising number of tourists are canceling their trips to the country for fear of suffering a natural disaster. The most curious thing is not that “frightened” of tourists, but what has unleashed it. Behind psychosis is not the government, a seismological organism, a team of physicists and geologists or a revolution, but a manga comic. THE KEY: A 1999 comic. If Tang has rethink his next trip to Japan, just like others Assiduous and passionate travelers of Japanese culture is largely by a comic released a few years ago. To understand it you have to go back to 1999, when Ryo Tatsuki published ‘WATHI GA MITA MIRAI’ (‘The future I saw’), a manga in which the author talks about prophetic dreams. The work could pass without sorrow or glory through the libraries of the country if it were not because in it Tatsuki predicted a great disaster that would occur in March 2011, month and year in which Japan suffered A great earthquake With thousands of dead and injured. That coincidence gave a huge reputation to the comic. He began to talk about him on social networks, he commented on TV programs and his specimens were revalued. And why does it matter now? The work ended up becoming so famous that the Asta Shinsha publishing house signed Tatsuki to publish a new version, a “complete edition” that was launched in 2021 and ended up becoming a bombing. The company ensures that in total more than 960,000 copies. The book has also been published in Chino and has reached other points in Asia in which it has become popular, such as Thailand or Hong Kong. The point is that this new enlarged version includes a prediction that has shaken Japanese tourism and has put on guard not a few travelers in Asia, especially superstitious. 2025. The comic ensures that “the real disaster will arrive in July 2025” (an idea that includes on its own cover) and leaves Sound passages as the following: “I dreamed with a great disaster. The waters of the Pacific Ocean south of the Japanese archipelago will rise.” Such prophecy (of course) has no scientific support and the author herself has recognized in An interview with Mainichi Shimbun that people should act “taking into account the opinion of experts”; But that has not avoided that the influence of manga (and its prophecy) has spread. A manga … And something else. Although Tatsuki’s comic has played a decisive role is not the only thing that explains that the fear of a natural disaster has downed (and remote) apart from tourists who planned to travel to Japan this year. The ball has been enlarged after an alleged “psychic” Japanese predicted that an earthquake would hit Tokyo’s bay April 26 (something that obviously did not happen) and Qi Xian Yua Feng Shui teacher with some impact on Hongkonese TV, will advise people to stay away from Japan. If that is added the social networks speaker, the result that I commented Tang With the CNN: “Everyone talks a lot about an earthquake.” “It is better to avoid it. It will be very problematic if an earthquake occurs,” coincides Oscar Chu, another Hong Kong traveler, who usually visits the country of the rising sun several times a year but has decided to rethink his 2025 trip. Beyond the prophecies. Predictions and prophecies on the margin, the truth is that Japan is located in an area of ​​special seismic activity, the Fire belt Del Pacífico, already throughout the last decades, has suffered earthquakes such as the one that hit the Kanto region in September 1923, the 1995 Hanshin-Awaji, Iwate-Miyagi Nairiku (2008) or that of 2011, which caused damage mainly at the northern end of the country. At the beginning From this same year he suffered another in the southwest area, although with a rather lower intensity, of magnitude 6.9. Not long ago Japan issued Another alert and the government He has recognized that there is a high probability that an earthquake shakes the Nankai pit (located to the south of the country) throughout the next three decades. TO mid -April Even the Chinese embassy encouraged its travelers to take precautions. Reality, like They recognize the authorities Japanese, is that “with current knowledge it is difficult to predict an earthquake specifying date, time and place.” How has it affected tourism? Although it is difficult to anticipate the Ladies, the fear climate largely fed by the Tatsuki comic, it is being felt in the Japanese tourism sector. Especially in demand from other points in Asia, such as China, Thailand or Vietnam, important markets for the country. WWPKG travel agency, based in Hong Kong, He has assured to the CNN that the reservations to visit Japan during Holy Week fell to half. And forecasts for the coming months are not better. Greater Bay Airlines, an Hong Kong airline, He has chosen directly For reducing their services with the Japanese region of Sendai and the city of Tokushima, cutting both in a weekly frequency. The reason: a drop in demand between rumors of an upcoming disaster in Japan that add to the economic uncertainty generated by the tariff war initiated by the United States. A BOOM SECTOR. The big background question is how this suspicion will affect the growing tourism sector of Japan, which has been moving in historical figures and has even generated tensions in the busiest points, such as the surroundings of the Mount … Read more

One more year, one of the most important appointments of the year with Google arrives. Today the Google I/O 2025one of the conferences (really a series of conferences) of the year that, how could it be otherwise, you can follow it live and direct with us. The opening conference of the Google I/or 2025, the one in which Google will present the most juicy news, will take place Today, May 20, at 7:00 p.m. Spanish peninsular. You can follow her live on YouTubein Our Instagram profile and on our direct page. The schedules according to regions are the following: Spain: 19:00 (18:00 in the Canary Islands). Mexico: 11:00 am Colombia: 12:00 am. Venezuela and Chile: 1:00 pm. Argentina: 2:00 pm. 10 Google applications that could have triumphed What do we hope to see Google I/O 2025 | Image: Google Surely he does not take anyone by surprise that the Google I/or this year will have the AI ​​as the main protagonist. Mountain View company is Betting very strong for Gemini and integrating this technology into all its productsfrom Android to the search engine, so it is likely that today we know not only new models, but new integrations and experiences in all its products. We are also likely to have information about Agentic And some novelty of PROJECT ASTRA. On the other hand, on May 13 it took place The Android Showthe separate event in which Google presented all the news of Android 16Wear OS and other systems. However, there was a name that did not have excessive prominence and that, surely, has it today: Android XR. The Google I/O 2025 will be marked by the same word that has marked all the events of recent years: AI This operating system, which we will find on devices such as Project Moohan (The glasses that Google is developing with Samsung), will also have Gemini as a co -pilot and aims to be Google’s next pass. The firm managed to conquer the mobile world with Android and with Android XR seems to aspire to the same in an incipient segment, but with great potential: the connected glasses. Daydream and Google Glass They did not come to fruition, but it is often said that the third will be the defeated. What we do not expect is hardware. Unless there is a surprise in the form of precisely glasses, we do not expect novelties of pixel, tablets or home automation. This event has all the ballots to be about ia, AI and a little more than ia. Recall: It will take place today, May 20, at 7:00 p.m. Spanish peninsular.

There is a great threat to the US if you send thousands of advanced chips from AI to the Middle East. That end in China

by

These days we have seen how Donald Trump has reached a series of unique agreements with countries in the Middle East. In them the protagonists are the advanced chips of AI that the US will export to Saudi Arabia or United Arab Emirates. The problem is who will really use those chips. Data centers in the desert. These countries announced projects for the construction of large data centers, although It is not too clear that they can complete them or that their dimension is what they promise. Even so, the agreements are very significant and promise the sale of thousands of Nvidia or AMD chips that will end up arriving in the countries of the Middle East. Internal doubts. As they point out in Bloomberg, some members of the Donald Trump administration are trying to slow these agreements. In the opinion of these politicians, the United States has not imposed enough barriers to prevent these chips from ending where they should not. China. According to that newspaper, agreements include clauses that theoretically They prohibit China You can access these chips through countries in the Middle East. However, US government officials believe that there have been too many details without closing and that the agreements should not be announced without being totally defined in that and the rest of the senses. Middle Chinese relationships. The company that leads in AI in the United Arab Emirates is G42, and the problem is that this company has historical ties with Huawei. It is true that it ended theoretically cutting those ties To get close to US companies much morebut there are suspicions by some US government officials about whether there is still a relationship with China. And there are other risks. Trump’s policies were supposed to reserve the vast majority of these most advanced AI chips for this country, but this agreement raises a danger: that Middle East nations have access to toe technology would give them an important competitive advantage. But better to make the agreements than them. Sources close to the situation reveal that if the US does not reach these agreements, those countries – and others in the future – could reach those same agreements with China. The Asian giant has been advancing in the development of AI chips, and although it still cannot compete with those of the US, its proposals They are increasingly promising. A strategic issue. David Sacks, advisor to AI for the White House, is the one who defends that argument the most. That would allow to avoid or at least mitigate the phenomenon of “shrinking” of the US advantage over China in advanced chips. It is something that Jensen Huang has spokenCEO of Nvidia, who believes that with all the measures to prevent China from having access to those chips what has ended up causing is that this giant activates its machinery to get rid of the dependence he had of the US. The great winner. Meanwhile, the truth is that Nvidia will be one of the great beneficiaries of the agreement, because it has closed an agreement with Saudi Arabia valued at $ 7,000 million. The impact on Nvidia’s shares has been immediate: the company’s stock market capitalization grew by 12,000 million dollars in a single afternoon.

The new great models of generative the AI ​​do not stop delaying. It is a dangerous indication that we have touched the roof

by

We expected to have GPT-5 available at the beginning of the year, but OpenAi gave us GPT-4.5. The generative AI model, which theoretically represented a remarkable leap with respect to its predecessors, ended up disappointing and the company announced that it will eliminate it from its API in July. It was too expensive and simply did not compensate. That was already a bad sign of AI advance, but there is more. And GPT-5, what? It was expected that GPT-5 will arrive in the middle of the year. Sam Altman has been creating Hypebut in December we knew that the arrival of that model was being problematic. The jump in benefits I wasn’t being expected And the cost of developing it is huge. What did they do in Openai? Delay it and launch in its place GPT-4.5 That, as we have seen, it was one of the great disappointments in the history of Openai. Bad signal one signal. Behemoth is delayed. As indicated In The Wall Street JournalGoal will delay the launch and deployment of its most ambitious model to date, call 4 Behemoth. This “monster” with 288,000 million active parameters (two billion in total) is the third member of the newly presented family calls 4. However, according to WSJ “Company engineers are having difficulties in significantly improving” their capabilities. It should have arrived in April, but now it is estimated that it will arrive in autumn, or even later. Frustration. Sources close to the company indicate that managers are frustrated with the performance of the team that is developing calls 4 Behemoth. “Significant management changes” are already contemplated that would raise internal movements (and who knows if layoffs) as a result of these bad results. And not that the available flame models 4 are having a good receptionlet it be said. Bad signal number two. Unbalanced. In WSJ also highlight how the first flame version was created by its fundamental research team, formed by academics and researchers. Since then 11 of the 14 researchers have left the company. Anthropic does not advance either. We also expected a “round” leap in Claude, the Chabot of the generative of Anthropic, but in February the company presented Claude 3.7. It is true that this model Yes offered striking benefitsbut at the moment its Opus version, the most ambitious, still does not appear, and nothing is known about Claude 4.0. Bad signal number three. Jumps not, at most jumps. What we are seeing in recent months are not significant leaps in the capacity of the models, but striking improvements only in some sections or effective characteristics. It happened with Gemini 2.5 Pro, especially powerful in programming and that has allowed Google to win integersbut also with Openai and the famous images that imitate Studio Ghibli Oa Grok 3, who has become more famous for his lack of censorship that for its accuracy or quality (which is not bad). Deceleration. All this triggers the debate on a potential “deceleration” of AI: the climb no longer seems to work so well, and that of using more GPUS and more data to train models is not offering the expected return. Jaime Sevilla, CEO of Cophai, I did believe That the rhythm of improvement was being expected, but these delays of course make the future progress of generative the AI ​​again. The agents and the AI ​​that “reason” are hope. The models with “reasoning” capacity Yes, they have allowed us to propose striking improvements in some areas, and companies have launched to present this type of variants and deep research modes For specialized uses. The other great hope of 2025 are the agents of AI capable of completing task sequences autonomously to solve a problem, even connecting to other services or data sources. At the moment we already have outstanding examples in the schedule of programmingbut practical applications for end users are limited. Image | Goal In Xataka | There are too many AI models.

Losing weight without losing muscle is the great challenge of drugs such as Ozempic. A protein keeps the key to face it

by

It is usual for us to often get news about hopeful scientific advances made in mice. These experiments always leave a question in the air, if the discovery can be applicable to humans. This does not always happen, but sometimes MITCH Silence the expression of a simple protein in our muscles can lead to weight loss and, more, more, It can allow us to lose weight Without putting our muscle mass at risk. The protein in question is called Mtch2 (Mithochondrial Carrier Homolog 2), but has been nicknamed “Mitch” by those who study the compound and its effects. The last analysis of this protein and its associated gene has observed that its “erased” in human cells causes in these lower efficiency Energy What is perhaps more important, this silenced causes cells to stop using carbohydrates as a priority energy source and in place they preferably use body fat. Different fuels. The cells of our body need energy and billions of years of evolution have given rise to a series of biological mechanisms that allow us to maintain a calorie reserve that allow us to feed these cells in times of greater shortage. These mechanisms imply that our cells can resort to different fuels according to the situation. While the carbohydrates we consume and the fats that we use as a reserve are the main fuel Ozempic. From mitones to mitochondria. According to Explain the responsible teamthe new study has its bases in a previous experiment conducted with mice that observed in the rodents an “improvement” in their body composition in the form of “protection” against obesity and the development of more muscle fibers. This accompanied by greater consumption of greater oxygen consumption and an increase in resistance. The results were promising but left the team with a doubt, if it would be possible to “inoculate” the body against obesity by silencing the expression of a protein without this negatively affecting muscle mass. To look for an answer, the team went on to focus on the role of the mitochondría, the organelle in charge of providing energy to the cell. The key is in the fact that the “mitch” protein plays an important role in the merger of the mitochondria, a fusion capable of increasing the efficiency of these organelles. By silencing protein, organelles would lose the ability to resort to this fusion which also implies less efficiency and thereby a greater need to consume energy resources of our body. It only remained to prove if this was also true in human cells. Less efficiency, more consumption. They thus verified that by silencing the protein in human cells, the “mitochondrial network” was undone and, as expected, energy efficiency fell. This left the cell in a “permanent state of energy deprivation.” And what is more, the team also found that this led to the cells to prioritize the use of fats as a primary energy source, instead of other possible sources such as carbohydrates. “After erasing Mitch, we examined, every few hours, the effect that it had in more than 100 substances that take part in the metabolism of human cells,” pointed in a press release Sabita Chourasia, co -author of the study. “We saw an increase in breathing, the process in which the cell produces energy from nutrients, such as carbohydrates and fats. This explains the increase in muscle resistance of previous experiments in mice.” The details of the study were published In an article In the magazine Journal embo. An intermediate step. The study takes an important step in the long process between the first results in animal models and the design of a treatment for weight loss based on what was learned. In following studies, the team intends to elucidate new aspects about Mitch’s role in the accumulation of fat in the body. The fact that women usually have higher levels of this protein can help researchers discover if Mitch is also responsible for the differentiation of fatty cells.
