DGT recommendations to face the output operation on August 1

by

They say that the flow of travelers has changed over our country. The holidays are usually chosen for weeks and not for fortnights, as before. Therefore, it is Fridays and on Sundays the days that are usually registered on roads in summer. But this year we have a particularity. This Friday is August 1, the day that was traditionally used to go on vacation. One more reason for The DGT theme that the roads become hell this weekend. The usual summer traffic between Friday and Sunday must be added that it begins (or ends) the fortnight, so a huge flow of workers who go out to enjoy their vacations or begin to return to them is expected. These movements, the DGT estimates, will add some 6.88 million journeys Between yesterday, Thursday, July 31, and Sunday, August 3. During all this time the Operation of August 1 will be activated. A campaign that gives the starting gun to a month in which they are expected to count about 52.87 million displacements. These are the recommendations of the DGT. Better with full tank What can we expect from an operation holiday? Traffic. A lot of traffic. That is why the DGT already advances that the most complicated hours will be condensed in the August 1 (starting at 3:00 p.m.), throughout the morning of Saturday, August 2 and, of course, on the afternoon of August 3 (between 4:00 p.m. and 23:00 hours) when they are expected to meet both those who go out to spend the day and those who have lengthened the entire weekend and, of course, those who return on vacation. What remains in our hands? The DGT gives a series of Recommendations. The most basic is that we move outside these schedules, whenever possible. Thus we will reduce the risk of seeing ourselves wrapped in a jam. But, in addition, they ask for a certain forecast: Prepare the trip: check the car components well, such as the pressure of the tiresbrakes or lightsthinking that you will demand much more than usual. In addition, have an eye on the browser to avoid possible jams and be aware of the possible accidents or breakdowns of other vehicles. During the trip the DGT emphasizes a “circulate with the Full fuel tank. It will be of great help in case of being faced with any anomalous situation as retentions, accidents or unforeseen weather. “This recommendation is usually given in winter where the fuel tank It is key to keeping heating alive of the car but it is always a good idea because, in case it is complicated and the night is over, we can have problems to find an open gas station or face an alternative route if, for example, for example, for example, for example, for example, A road has been cut by a fire. Food and drink: always carries water inside the car and avoids heavy meals since they can sleep. Of course, try to sleep as well as possible before and drive rested. And the DGT ends with a sentence: “Do not take the mobile and avoid any other distraction. Your only task is to drive“ Photo | Tsai Derek In Xataka | The problem is not that the air conditioning of the car breaks more in summer.

The US has realized how risky it is to continue pressing China. His reverse looks for a “face to face”

by

The US is softening its export restrictions to China. In early July, the administration led by Donald Trump allowed Nvidia to sell Your H20 GPU To its Chinese clients. At the time This movement surprised us because it clearly indicated that an obvious change was consolidating in the US strategy in front of the nation governed by Xi Jinping. According to the newspaper Financial Times This relaxation of export restrictions to China seeks to “avoid damaging trade negotiations with Beijing.” And it is presumably this week US and China will resume their negotiation to establish the rules that will resolve their future commercial interests. As expected, this rudder of the US administration favors the interests of Nvidia, AMD, Broadcom and other companies, but not all members of the Trump administration support this initiative. According to Financial Timessome White House advisors are pressing the government to maintain their blockade to China. Nvidia needs TSMC to manufacture 300,000 H20 chips for China Donald Trump wants to meet “face to face” with Xi Jinping before he ends this year, again according to the information he has Financial Times. The intention of the US president is to file roughness with his Chinese counterpart with the purpose of promoting negotiation in commercial matters that both countries have maintained for many months. Just a few hours ago they have gathered in Stockholm (Sweden) Scott Besent, the US Treasury Secretary, and He Lifeng, the Vice Prime Minister of China, so it is evident that the negotiation follows its course. After many months of uncertainty the current scenario clearly benefits Nvidia. The company directed by Jensen Huang saw its survival in China threatened by The sanctions approved by the Department of Commerce from the US, but This volantazo changes everything. And its protagonist is the chip for artificial intelligence (AI) H20. The reception that Chinese clients of Nvidia initially gave to this GPU was very good despite the fact that the capabilities of this chip are clearly inferior to those of the other proposals for this company. After many months of uncertainty the current scenario clearly benefits Nvidia In fact, initially the Department of Commerce allowed its sale in China because this integrated circuit met the restrictions it had imposed. And despite its limitations its sales in China grew by 50% quarter to quarter since it reached this market in mid -2024. Everything was complicated for Nvidia in the middle of last April. And is that the US Department of Commerce imposed new restrictions To the export to China of the H20 GPU, which in practice caused this chip to stop reaching the Chinese clients of this company. This news sank Nvidia’s actions by 6% because it could no longer address the commitments linked to the H20 GPU it had acquired. Among the Chinese customers who had bought it Large amounts of this GPUand presumably planned to continue doing it, were Tencent, Alibaba or Bytedance. Finally Nvidia has achieved That the Department of Commerce review its regulation and allow you to sell the H20 GPU in China again. Surprisingly this scenario has put Nvidia in trouble. And, once again, the reception of the H20 GPU in China is being so good that this American company has run out of units. According to ReutersNvidia has commissioned TSMC for the manufacture of no less than 300,000 units of this chip to be able to respond to the current demand from China. Blessed problem. However, the company’s engineers have been working on A new GPU with Blackwell microarchitecture The latest generation that is intended to occupy in China the place of the H20 chip. In fact, presumably TSMC began in June the production of The B30 GPUwhich is how it seems to be called. What we know at the moment is that this chip for AI will be less capable than the H20 GPU, as is logical, and also that its price will move Between 6,500 and $ 8,000. For domestic users it is a lot of money, but in the field of professional GPUs for AI it is a moderate price. In fact, the H20 GPU costs between $ 10,000 and $ 12,000.

Renfe trusted the Avril trains to face the Low Cost of Ouigo and Iro. They do not stop giving problems

by

When the competition has pressed, Renfe has seen how his commitment to a low -cost service to the AVE had been as necessary. The problem is that this service, called Avlo, is operated by trains that in just over a year have not stopped giving problems. Retired avlos. It has returned to normal with the five Avlo trains frequencies between Madrid and Barcelona for the month of August but for a few days the cheap offer of the company in the corridor faded completely. First the five trains retired. Then the frequency was in three options in the day. Finally, they can already be bought normally. It is what Víctor de Elena accountjournalist electionomista.eswho had written an article last Friday explaining that Renfe had stopped offering his services of the Avlo line between Madrid and Barcelona. Since last Friday, when the information was published, the sale of tickets has been returning to normal. What happened? Everything indicates that Renfe has been putting patches to a complicated situation. He explained about Elena that Renfe had found a fissure in one of the components of the Bogies of an Avril train. This would have caused that, temporarily, it would be suspended The sale of all Avlo tickets in Madrid-Barcelona. Hours later, Renfe sources would confirm to the medium that during one of the maintenance reviews last Monday, July 21, one of the five 106 series presented “a fissure in an element of the tractor bogie called a bast.” Subsequently, a review of the five trains that serve and the affected systems were replaced. Now, according to Renfe “trains are operating without any anomaly.” More slowly. The trains operate, yes, but below the expected speed. They point out in electionomista.es That according to the State Railway and Adif Security Agency, Renfe operates the trains at 250 km/h of maximum speed, instead of the 300 km/ha those who were operating in a stretch of 190 kilometers that extends between Puerta de Atocha and Ariza (Zaragoza). In your communicationRenfe points out that the company “through its Renfe Travelers and Renfe engineering and maintenance, as a railway company and entity in charge of maintenance, respectively, as well as Talgo in its condition as manufacturer and the State Railway Security Agency, guarantee that the circulation and operation of trains is carried out with total security for travelers.” In the statement they point out that the offer is being reorganized with the S106 trains but do not specify anything about the speed at which trains circulate and emphasize that the sale of tickets is being made “normally.” In Xataka We have contacted the company but so far we have not obtained an answer. The Avril. The S106 series in which the fault has been detected corresponds to the trains known as Avril. Trains that since they were launched in 2024 They have caused various incidents. The S106 series It is designed by Renfe to fight the lowcost but also to be able to offer a service in Galicia that You will not have competition in the short term. For this last line, Renfe has 15 trains in his hands that can change the wide track automatically. Then, it has another 15 trains to operate between Madrid and Barcelona. Of the latter, they carry the specifications to operate as AVE but in five other trains the places have increased from 507 to 581 seats and thus be able to compete as a low cost option. A controversial arrival. When the Avril trains made an appearance they have already arrived surrounded by controversy. They launched in May 2024 but The material had been delivered with three years delay. Then, of the 30 trains, 12 of them had been delivered in a first lot. The first steps of the Avril were not the best. They promised to improve the connection between Galicia and Madrid but in the first days they registered delays of more than two hours and in later days of more than 30 minutes. Neither In the Asturian line The promised time sales were being fulfilled. But, in addition, the trains did not like among the experts either. Accounts in social networks that follow the current world of the train and its novelties portrayed the excess noise and vibrationsas well as They questioned the quality of some materials used in the rolling material. More incidents. The incidents did not stay here. Above all, Avril trains are remembered by the fault in the Galician line that on the first day of this year he left thousands of passengers on the ground or in the middle of nowhere. In a kind of “2000 effect”, trains were retained by a software problem With the year jump. And Barcelona-Madrid has not been the only one. Just a few days ago, a S106 series train collapsed at low speed at the Gijón station without consequences for travelers. At the moment, Renfe has not given explanations about what happened.

The United States has lost almost all its advantage in the face of China. And in just over a year

by

American leadership in AI wobbles. The data of the AI Index 2025 Stanford reveals that China has trimmed the technical advantage of the United States to levels that seemed difficult to reach. Above all, because it has taken a little over a year to close most of the gap. Why is it important. The United States maintains the volume –40 notable models against 15 Chinese at the end of the year in the Epoch list-but China has shown that quality is no longer American monopoly, and that almost-convergence rewrites the rules of geopolitics in the most promising and strategic technology of the 21st century. The figures. In January 2024, the best American model exceeded Chinese in 9.26% in Benchmarks of chatbots. Just over a year later, that advantage has collapsed to 1.7%. Convergence is repeated in reasoning, mathematics and programming. The case Deepseek It is a perfect example. While Google spent 192 million dollars on the specific training of Gemini 1.0 Ultrathe Chinese startup said they have achieved competitive results with just 6 million. That caused A media and stock market earthquake At the beginning of the year. The contrast. They are two different approaches: The United States dominates for quantity and resources: it leads private investment (150,000 million dollars in 2024) and concentrates the most valued companies in the sector. China is responding efficiently: less models, much lower costs, equivalent results. The narrative of “Chinese technological backwardness” falls apart. Yolanda Gil, co -director of AI Index, He explained Thus his surprise: “I hoped that a more efficient version of the LLMS appeared at some point. We simply did not know who would build it or how.” Yes, but. American hegemony persists on other fronts. American companies continue to create the most influential models and monopolize global investment. And Europe is relegated: only three notable models in 2024. All French. The shadow of Mistral. The background. This race reflects a broader battle for the future of the digital economy. China demonstrates that efficiency can compensate for huge spending, challenging the “brute force” model that has characterized US development of AI.

Apple has not washed the iPhone’s face. Has subjected it to cosmetic surgery

by

Forget iOS 19 and stay with this name: iOS 26. This is the beginning of a new stage. The protagonist operating system of the WWDC 2025 that Apple is celebrating in Cupertino is that of the iPhone, and drinks directly from an interface we already knew: The Vision Pro. Apple’s most niche device is the one that will mark the way for the rest of the products. Some that, in this new stage, will have a name and A unified design language. Why iOS 26. The logical jump after iOS 18 It was iOS 19, that’s over. Apple will begin to rename its software platforms by adding a +1 a year in which they are launched. We are in the year (20) 25, adding that one we already have the 26. It is the name that the rest of their brothers will receive: Visionos 26, Watchos 26, Tvos 26 and Ipados 26. Next year, we will have versions 27 above the table. A name change that meets a concrete need of Apple: to try to make its operating systems to the fullest. Liquid Glass. The first novelty of iOS 26 has to do with its change at aesthetic level. Apple has been inspired by visionos to share its design language with the rest of the software platforms. And he has decided to call him Liquid Glass. The translation is simple: a system starring transparencies, rounded icons and even softer animations. The changes range from the application pitcher to the apps themselves, a work that the developers will have to begin to adapt to maintain coherence with the renewed system. News at Apple Intelligence. Apple wanted to start (in a very short way) its Keynote with news in its artificial intelligence functions. A good part of them, not yet available in Europe. Among them, The new Siri. One of the big changes is how applications will interact with Apple Intelligence. Developers can configure their apps to directly access Apple Intelligence, privately and even without connection. Image | Apple

Three watches for less than 200 euros to run. We face them on the ground and we already have a winner

by

Going to run with a smartwatch sounds tempting. But when prices range from less than 200 euros up to about 900 euros, it is normal to ask if it is worth paying more. What do we lose when we opt for a cheaper model? And what do we continue to win? In our new video we face three affordable watches that seek to offer us several answers. That is why in Xataka We have prepared a new video For our YouTube channel With one of our favorite formats: the Versuswhere we compare face -to -face devices to discover which one deserves more. In this new comparison we face them Garmin Forerunner 55he Amazfit Active 2 and the newcomer Huawei Watch Fit 4. For several weeks, our partner Mario Arroyo has run about five times a week with each of them. “I have been testing what are the three best watchesTo start running and I’m going to tell you why this is the best ”, starts in the video. The goal is clear: check which best meets in key aspects such as comfort, drums, sports functions, experience of use and mobile applications. As for comfort, the three models fulfill well, although one of them feels “slightly thicker and heavier.” The biggest difference is in the way of interacting: Huawei and Amazfit bet on Amoled touch screens, while Garmin resorts to buttons. At first it may seem uninitive. “Uncle, it is very little intuitive,” said Mario, but soon found an unexpected advantage. After running, the analysis comes into play. The apps of the three offer data and statistics, But with clear differences. Garmin Connect is the most technical and deep, while Huawei Health and Zepp (Amazfit) are more visual and intuitive. In this Versus We will try to discover which one that can help us continue to progress. Mario also explores which proposals fall short as smartwatch, as well as related to autonomy. “I have trained a lot with them for a lot of time to be able to make the most precise possible comparison and having so many an hour training, I think they are very good data,” he summarizes. Will anyone stand out? You can discover all the details and the final conclusions In the new Versus On the Xataka YouTube channel.

Ukraine soldiers are starting to carry scissors. It is the only way to face Russia’s most lethal weapon

by

At the beginning of January the New York Times told which was no longer possible to hide in the Ukraine War. Before the brutality of the contest a technology had sneaked into Evade electronic war and enter the enemy field of both sides as I had not done before. The threat was destroying the lines, making attacks invisible and evading any attempt at interference. Now, that technology has become stronger and deadly in Russia: the optical fiber. The Russian offensive. I explained it a few hours ago BBC in a report. In the Ukrainian town of Rodynske, a few kilometers from Pokrovsk, the war has acquired an even more devastating dimension with the intensive use of 250 kg planning pumps and surveillance and attack drones. The recent impact of one of these projectiles devastated administrative and residential buildings, leaving behind a destruction landscape. Russian troops, unable to take Pokrovsk directly, have begun to surround it strategicallycutting supply routes through a siege that intensifies with every day. The immediate presence of Russian drones about Rodynske reveals that Moscow has advanced from the east, beyond the previously identified positions, displaying their weapons since recently captured areas. The unstoppable rise of fiber. Under that changing scenario, a technology has been perfected as the most feared weapon in the conflict: guided drones by fiber optic cable. Unlike traditional models, their physical connection with the controller makes them immune to electronic interference, one of the most important defensive pillars so far. Although slower and can be tangled (for example, in their passage through trees high), their ability to operate in closed environments, such as Inside buildingsand to stay hidden, each movement of Ukrainian soldiers converts into a possible death sentence. In that sense, Russia has taken the front in its implementation while Ukraine still tested themand although now tries to accelerate its production, the technological difference continues to incline the balance on the battlefield. Fiber cable anchored to a drone in Ukraine The front lines. This new type of threat has completely altered the dynamics of Ukrainian detachments. Soldiers as it is or came, from the 68th Jaeger battalion, They described the BBC How simple transfer to a position can be more lethal than direct combat. The pressure has forced the units to remain much longer in the trenches, without the possibility of rotation. Maksym, gunner of the 5th Assault Battalion, says that they could alternate every few days, but now there are those who take until 120 days in a row on the front. Fatigue, moisture, constant death and the impossibility of lowering the guard have redefined combat. Oses, chief of recognition, explained that Russian tactics have evolved towards small and mobile infiltrations: Motorcycles, quadrimotos, patrols of one or two men who penetrate enemy lines such as scattered pieces on a chess board. Pros and cons of fiber in war. Detailed it in a Interview for The War Zone Yas, a commander of the Ukrainian unmanned units (drones). Operate drones by fiber optic offers an essential tactical advantage: it allows silent control, without detectable emissions, and makes many electronic warfare systems obsolete. However, the system also presents limitations. Drone management It requires great expertisesince an inexperienced pilot can cause losses due to control failures or even unwanted explosions. In addition, the fiber cable can be easily broken or entangled, and technology itself is expensive and difficult to access (especially for Ukraine). Despite this, the success index of fiber drones to achieve and hit their goals Round 50%figure that clearly exceeds that of conventional radiofrequency drones. However, less than 5% of the Ukrainian drone park, According to Yascurrently uses this system, mainly due to the shortage of quality units and the saturation of local manufacturers, many of which, in the beginning, reversed Chinese components without fully understanding the operating requirements in combat. The asymmetric race. In that sense, Russian capacities are not only imposed by number, but by the speed with which Adapt solutions. Every time Ukraine changes frequency or introduces improvements, Moscow responds quickly, climbing his countermeasures in a coordinated way. He has done so with control channels and video transmission. In that context, fiber optic drones They represent a momentary tactical advantage window. Although in Ukraine ranges of 15 and up to 20 kilometers with drones of this type have already been reached, Russia operates models of up to 30 kilometers. Yas lamented to the environment that, except in the case of conventional drones, the Ukrainian State has not yet managed to establish A solid infrastructure of production and deployment for fiber optic drones. A gap that can determine the difference between maintaining defensive positions or losing strategic ground against the enemy. Endurance. In The BBCa Ukrainian soldier said that the fear of drones Invisible Because of the fiber he has led them to start carry scissors everywhere To cut the cables. Technology has already given enough episodes of authentic nightmare where drones have entered buildings chasing human objectives. Meanwhile, and although Russia has made important advances, the Total Take Donetsk It is still far from being an immediate reality. Ukraine continues to resist, but suffers the shortage of ammunition, the imperative need for weapons and a worrying lack of qualified personnel against a more numerous Russian army and with better institutionalized processes at the moment. Yas is clear: The future of the war of drones will depend not only on technology itself, but who is able to organize it and multiply it faster. Meanwhile, every drone that raises the flight with a fiber optic coil becomes a silent bet between life and death.

Machu Picchu has become a world tourist destination. Now face the unwanted consequence: die of success

by

Machu Picchu is one of the most popular icons in Peru, one of its greatest heritage treasures and a powerful magnet for tourists who only during the first two months of 2025 attracted more than 191,000 visitorsalmost 17% more than in 2024. For that reason, the Inca citadel of Cusco faces the same threat that looms over other large international destinations, such as Mount Fujithe monumental areas of Rome, Venice and Florence either The pyramids of Guiza, in Egypt, to cite only a handful of examples: tourist saturation. So They just warned The Peruvian authorities, who have launched a notice to navigators: the “tourist overload” of the Inca city threatens its conservation. What happened? That the Would control general Of the Republic, an autonomous body responsible for ensuring the assets and resources of Peru, has just made a warning to the country’s ministry of culture: Machu Picchu is suffering a “tourist overload.” The problem has been detected both in the old citadel and in the Inca road network (Qhapaq Ñan), he Road System of the Incas. After verifying the influx of visitors, the general control has come to the conclusion that there is an excess of tourists that puts “at risk” the conservation of both points and affects their “structure and ecosystem.” And if that message had not been clear enough, warns: To extend, that situation could lead to Machu Picchu ending in the World Heritage List in Danger of UNESCO, a risk that he already faced A few years ago. What is the problem? The Peruvian agency provides concrete data to support its complaints. Between April 17 and 30 of this year its operators detected “an overload” of 2,505 people on the upper terrace of the Inca city (Route 1-B). And it was not an isolated case. In May they estimate that this saturation will reach 1,546 users. What does that mean? That authorized maximum aguoros are repeatedly overcome in the protected space. “Although the sustainable access limit to said AES area of ​​450 people per day in regular or low season, the sale of tickets for daily income from 549 to 789 users was evidenced. And while in high season the limit is 490 people, access tickets of between 495 and 639 users were sold.” The key, They need From the control, although the state platform for the sale of tickets is respected the capacity of the upper terrace of the LlaqtaVisitors arrive on the road network. Is there more data? Yes. The agency has also detected a considerable “overload” of 836 visitors, on Route 5 of the Inca road network between April 17 and 30. In May the data will amount to 1,490. “Although the permitted capacity is 250 people per day, the sale of tickets for the entry of 300 users between tourists, guides and support personnel was evidence insist From the entity. In the case of the Route Route designedanother of the great tourist claims in the region, saturation reached 1,368 visitors during the last 13 days of April and set 1,248 people in May. The control even speaks of “errors in the sales platform” that “make it difficult to plan the number of visitors.” Why is it a worrying? Because that excess tourists can take its toll to the deposits. “These situations do not guarantee the conservation of the areas because the constant transit of visitors could cause the erosion of the soil in areas with pronounced slopes and nearby areas, as well as the compaction of the land due warns The entity. Something similar would happen on the route, where the technicians consider that the “overload” endangers the residential and ceremonial area for the wear of the stone. Is it something new? Yes. And no. The touch of attention of the control of the Ministry of Culture of Peru is new, but as it is responsible for remembering the body itself in Your official statement It is not the first time that the preservation of Machu Picchu generates debate. In 2017, UNESCO He examined the situation of the Inca citadel to decide whether or not to include it in the world heritage list. The problem, explained at that time from UNESCO, was not so much the state in which the sanctuary was, as the management of the “long -term” environment. “The difficulties are in the control of tourist flow in the area”, warned. E that occasion the Unesco chose not to register To Machu Picchu on his list, but he would control it, he remembers that this option could be on the table again. Is it a real risk? I would control it like this seems to believe it. In fact, he recalls that at the UNESCO World Heritage Committee meeting held in July last year in New Delhi, the state of the Inca deposit was approached. “Concern about the state of conservation of the historical sanctuary was expressed in relation to several aspects, including the high number of daily visitors that has generated pressure on the structures and the natural environment of the site.” The truth is that Peru It has moved token so that his great tourist claim does not die of success. At the beginning of this year the authorities of Cusco and the headquarters of the Archaeological Park of Machu Picchu They announced that would reinforce the safety and control in access to the citadel after a field guard be convicted of accepting bribes to pass to tourists skipping the rules. To avoid repeating episodes thus Cusco promised to reinforce inspections by the police and install cameras. Machu Picchu is one of Peru’s great claims: only during the first two months of 2025 attracted More than 191,000 peoplepromoting national tourism to record figures.

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.

Xiaomi needs a new face

by

There was a time when Xiaomi could afford to be a sympathetic logo, almost toy. A funny nickname (“mi”), a simple aesthetic not to say Ramplona, ​​a spirit of accessibility and carefree. Okay. He was born as the brand that democratized the smartphone, The brand that competed in pricebut not in prestige. That time is over. In the Shanghai Motor Show it has been clear to us that Xiaomi no longer plays that game. With the Su7 ultraits first electric car in the upper version, Xiaomi changes its screws: it no longer competes by volume, competes by status. It does not seek to be the cheap alternative to Tesla. He wants to be the direct alternative. He even wants to overcome. The problem is that their brand, its visual architecture, their story, have not followed that jump of ambition. Today, Xiaomi sells mobiles of more than 1,500 euros. And it does it more and more often. It goes up to the podium of computational photography, of the design of noble materials, of functional luxury. And now he launches a car that, in finishes, technology and presence, rivals you with Porsche or Lucid. But continues to carry the same logo as when he did 200 euros phones that at three years ended in a drawer. It is not enough to change the product. You also have to change what the world sees, feels and projects about you. A brand is not just a name or an emblem. It is a silent promise, an unconscious expectation, a frame of reference. Today, the orange logo and the nice “Mi” continue to refer to the old Xiaomi. To that of shelves at ground in Medamarkt. No to the xiaomi that builds 500 horsepower, or Pulido Titanium Mobile. Not to the Xiaomi who wants to be a cultural and not just technological reference. That dissonance between what Xiaomi is and what seems to be is its greatest risk right now. Because brand coherence – that invisible red thread that joins product, perception and aspiration— It is essential when you want to play in the leagues where each nuance matterswhere each gesture counts. Apple was never just a logo. It was an aesthetic. A narrative. A visual discipline. A coherent language between hardware, software, packagingstores and communication. Xiaomi is reaching a product level capable of playing in that league. But the language of its beginnings continues. Keep asking respect with a teenager voice. And if it does not correct that lag, His ambition will collide with skepticism. Against a friction that is barely intuited today, but that can crystallize in a subtle but lethal distrust: that of those who admire the object, but does not finish believing the brand. The moment is now. Image: Xataka. It was not so important that the flagship on the hood of the ultra was gold and carbon fiber how to change its image. A superficial redesign is not enough. Xiaomi needs a new brand architecture: more sober, more refined, more deliberate. A brand capable of sustaining ultra -premium mobiles, electric shots, and whatever comes later without anyone blinking. Perhaps a double architecture – an accessible base xiaomi and a different submarine for the aspirational. Or perhaps a deep and unique evolution. But not remain the same. He already encouraged to transcend his original brand, but consolidating chaos instead of building clarity. The Ultra has not only shown that Xiaomi knows how to make extraordinary cars. Has demonstrated, above all, that It no longer makes sense to continue looking at Xiaomi as the usual brand. Now that Xiaomi also understands. And act accordingly.
