Our reservoirs have a serious structural problem. And experts have been warning us for years

by

Drought has been one of the recurring themes of recent years. Both the lack of rains and their diverse consequences have more than a five years in the informative agenda. That is why the question of how much water we have left has asked Very diverse ways. There is only one problem: we are not really able to answer it. Moreover, what we know that our water reserves They are usually below what the data indicates. The reason is in something as natural as erosion and sedimentation processes, but its consequences They have been worrying the experts for years. Throughout their channel the rivers transport small particles of rock and organic matter that tend to accumulate at certain points of the route, either on the river bed, in river deltas or in its meanders. The reservoirs are another of the auspicious places in which the water tends to “release” these particles. The swamp floor Thus tends to accumulate sludge. The first problem that this generates is the loss of swamp capacity. The higher the volume of this occupied by sediments less is the amount of water it can store. The second problem is that we do not know exactly how the sediments accumulate in each swamp since it can vary depending on the characteristics of each basin and each reservoir. If we don’t know how many sediments we have, we can’t be sure how much water we have left. The weight of the terrams Estimates on the weight of the terrain, which is how this accumulation of sediments is known in the reservoirs, vary. A Batimetry Study made in 2018 For the Tajo Hydrographic Confederation in the Entrepeñas and Buendía reservoirs, he estimated that the accumulation of these sediments was insignificant. At the opposite end, Another batimetry studyis made by the Segura Hydrographic Confederation, estimated that its reservoirs could have lost between 10 and 40% of its capacity due to the incidence of this phenomenon. They highlighted the case of the Lorca reservoir, built at the end of the 19th century, which would be at the upper end of this fork. Estimates made for the whole Spanish reservoirs are limited. A study conducted from 110 reservoirs estimated that The loss of capacity could be around 5%. José Luis Casamor and Antoni Calafat, from the University of Barcelona, They warned in 2018 that uncertainty was high in this estimate, since the possibility of extrapolating the results of this study to more than a thousand remaining reservoirs was limited. This is a problem on which experts carry years warning. The study carried out in the Segura Basin, for example, was carried out in 2017, while Casamor and Calafat’s work was published in 2018 in the publication Earth and technology of the ICOG (Illustrious Official College of Geologists). In a second article (also published in 2018) in The conversationCasamor explained that that of terraces was a problem with “faces and difficult execution” solutions “. Cleaning the sediment reservoir bed is an arduous task that requires the emptying of the reservoir, something that can be even more complicated in old reservoirs, explains Casamor. Prevention is a better option for this expert. This is to incorporate knowledge about the accumulation of sediments in the infrastructure design process. Another inclusion of dikes prior to the reservoir may contain the sediments up so that they do not accumulate in the reservoir. Other proposed measures to contain the sediments upstream include reforestation. The plants contain the erosion of the soil, which makes less particles reach the rivers and from there to the reservoirs. In this sense, rural abandonment has also been indicated as partial responsible for the situation. The fires also contribute to the arrival of sediments to the channels, so the fight to contain them can also contribute their grain of sand.

What if we are doing the bad intermittent fasting? Some experts propose to focus only on carbohydrates

by

Losing weight is not as simple as subjecting our body to a caloric deficit. Diets based on ingesting less calories than our body consumes work well in some contexts, but their medium and long term effects are limited by our metabolism and by our own constancy. That is why the intermittent fasting It has become one of the most popular diets for those who want to lose weight. Question of alternatives. Now, a group of researchers He has found A way to make these more affordable diets. The idea is based on making this diet less restrictive, limiting only carbohydrate intake in the days of temporarily limiting our caloric intake. Intermittent caloric restriction. Diets based on intermittent caloric restriction, which we often refer to as intermittent fasting Although they do not always imply fasting, they are based on limiting our food intake over time. There are different strategies to perform this fast, such as fasting 5: 2, in which we severely restrict the calories we eat for two days and eat normally the rest of the week. To understand the usefulness of This type of diets We have to remember how our metabolism, in an eagerness to protect ourselves from scarcity, can limit the success that conventional caloric restriction when weight loss. And our body reacts when we give less food, limiting our energy consumption to save resources, which ends up implying that when we ingest less calories, in the medium term our body also ends up consuming less energy. Cardiometabolic health. According to Adam Collins, co -author of the new study and researcher at the University of Surrey, In an article for The conversationintermittent fasting has an added advantage. It is about improving our “metabolic flexibility” since it allows us to balance the energy sources that our body, carbohydrates and fat reserves. This in turn implies a lower risk of problems such as cardiovascular diseases or type 2 diabetes. The new study signed by Collins and his team sought to inquire about the reasons why this improvement in our metabolism is given when we follow this diet. Since these types of diets focus on the idea that our body goes from using carbohydrates as a source of energy to consume fats, the team decided to study the implications of a limited carbohydrate restriction over time. 12 participants. The 12 participants In the study, overweight or obesity adults, they passed for two days of separate food restriction for five days of “rest.” One of the restriction days, the participants consumed a low diet in hydrates, while the other day they consumed a diet based on the chlorical reduction (consuming 75% less calories with respect to what would be common). The days following the restriction day the participants consumed a high ration in fats and sugars. What the team observed is that both diet forms showed similar results in each type of diet. The details of the study have been Published in an article In the magazine European Journal of Nutrition. Looking for answers. As explained by the team responsible for the analysis, new studies will be necessary to better understand this relationship and to strengthen this notion with a broader population. The team emphasizes that each of the diets (carbohydrate restriction and temporary restriction) entail Your own problemsbut perhaps combining them allows us to make these more bearable diets and with it more affordable and with a lower risk.

If the question is which car will not leave you lying on the road, the German experts are clear: the electric

by

More and more drivers They bet on electric cars And, with it, the Reports about your reliability They become more precise and complete because they provide more real data on the wear of their pieces over time. He last analysis of the ADAC, The main automobile club in Germany has thrown surprising data on the frequency of roads on the road, comparing electric and combustion vehicles. We have a clear winner. Thrown on the road. He ADAC studymade from millions of road assists, reveals that electric cars have a lower breakdown rate than their fuel or diesel combustion counterparts. This data is essential for those looking for a reliable car and with less possibilities of stay on the road. The analysis is based on 3.6 million road assistance operations, of which only 43,678 went to electric cars, which represents only 1.2 % of the total. Although the percentage of electric cars in circulation is much lower than that of combustion cars, the fault ratio remains well below compared to the thermal models of the same antiquity. The data leave no doubt. Adac data has only taken into account cars of which, at least, 7,000 units have been enrolled in Germany in the last two years, which leaves a sample of 160 models of 20 brands other than two and nine years old. If vehicle data is compared four years old, the Road Assistance Service It served 8.5 electric cars damaged by every 1,000 existing cars, compared to 12.9 combustion cars per 1,000. For cars between two and four, the difference is even greater: a ratio of 3.8 breakdowns per 1,000 electric versus 9.4 per 1,000 combustion cars. These numbers show that the electric ones fell half that the thermal models. A simpler mechanic, less breakdowns. The main reason for this difference lies in the Mechanical simplicity of electric cars. Having less mobile components and mechanical systems, there is less likely to suffer a breakdown that requires road assistance. For example, electricity do not have traditional gearbox or complex exhaust and cooling systems, which significantly reduces critical fault points. However, the most common breakdown in both types of vehicle remains the 12V auxiliary battery that tends to be downloaded more easily due to use in starting systems and the greatest demand for electronic systems. In the electric, 50% of the faults are related to this component, while in combustion the 45% of the assists. Tesla leaders, Hyundai to the tail. The ADAC report also analyzes reliability by brands and models. The data show that Tesla is the brand with less incidents registered. Thus, the Tesla Model and has a ratio of only 0.9 breakdowns per 1,000 units and Model 3 drops to 0.5 faults per 1,000. Other highlighted models in this section are the Volkswagen ID.4 with a ratio of 1.0 and the Audi Q4 e-tron with 0.7 failures per 1,000 vehicles. On the opposite side, as a vehicle with more registered assists, there is the Hyundai Ioniq 5, which in two -year -old cars has registered 22.4 breakdowns per 1,000 vehicles. Discordant notes. Toyota, considered one of The most reliable brands In different reliability rankings, it obtains a alarmingly high assistance ratio in its Yaris and Yaris Cross models. According to the study authors themselves, Toyota has already taken letters in the matter indicating that it is an incidence in the 12V battery configuration that discharged them, but that was solved in the new units produced in 2024. The data obtained by ADAC contrast with the Obtained in the Itv German (Tüv), where the Tesla Model 3 was the electric with the most failures detected, especially in headlights, brakes and suspensions, being below brands such as Dacia in general reliability according to this organism. The electric approve with note. The electric car market is relatively recent, so Adac clarifies that its conclusions are based on data data with an age of between 2020 and 2023, many of them being the first versions of their models. That leaves a current photograph but still limited in time. As increase the electric car park and These vehicles agethe records will be increasingly precise and complete, allowing to detect problems of long -term reliability. However, these results already allow an idea of ​​the reliability offered by the electric car and the evolution it will have in the coming years.

Experts begin to think that the problem is not mobile phones, but the algorithm

by

He wrote Hermes Trismegisto in his Kybalioneverything in creation has its rhythm and that rhythm, if we follow it, always takes us back to the beginning. It takes us to the world as will and representation, in the way Zaratrusta spoke, to the recurrence theorem of Poincaré … and, of course, to the discussion of whether the technology is leaving us fried by the brain. Or, rather, what, how and why it is affecting our cognitive ability. Because the fact that something is changing nobody discusses it. And how to discuss it? Of course something It is changing. And not only functionally, the changes are structural and all levels. The simple presence of screens It has substantially modified our somatosensory cortex; That is, they have changed the way we touch the world. There is nothing. But the situation goes further: how Manuel Sebastián explained years agoresearcher at the Cerebral Cartography Unit of the Complutense University, “we know that the text that includes links (hypertext) seems to remember worse in general, which is totally logical because they constitute distractors and the role of attention is critical in memory.” We knew that, but we didn’t know what it meant. “The fact that information is processed differently is not necessarily bad,” Sebastián told us. In the background, our brain Life is reorganizing And historically, that has been a good news. The question is, therefore, if it will continue to be in the future. And there are many experts who believe no. Data are not lacking. As John Burn-Murnoch explained in the Financial Timesalthough in recent years we have lent a lot of interest in the impact of pandemic on the cognitive and emotional development of young people, there are more and more experts who think we are not seeing it in perspective. Both the scores of most standardized tests of the world (as the PISA report) and Some specialized surveysThey point out that the problem began to appear in the mid -2010. And that problem It has many faces: From the difficulty to concentrate on the problems to learn new things. It is a bit complicated. Because, the truth is that, if we look at things like the time of use of screens and cognitive or emotional problems, we discover that There is nothing problematic. The traditional explanation has been that the important thing is not that we use new technologies, the important thing is what we do with them. And that’s where the algorithm enters. Because, As Burn-Murdoch saysthere is a change perhaps more fundamental than mobiles and networks: “the change in our relationship with information.” We have gone from web pages limited to infinite and constantly updated feeds, with a constant notifications bombardment. We no longer spend so long navigating the web or interacting with acquaintances, but we find a content torrent. This represents a transition from self -directed behavior to passive consumption and the constant alternation of context. And that’s where the problems may be. Unfortunately, There is still little research on this And, to the extent that everyone has launched this type of technologies and algorithms, we find a very difficult area to investigate. The good news is that, little by little, we are clearing the issue. The bad is that there is still much to know, even, the impact of all this. And, despite everything, as we usually check Every time an extensive study is published On our relationship with technology, there are no great alarm signs. Anyway, it seems that the plasticity of the human brain Find the way of “returning home”to overcome possible obstacles and catch up. Hopefully let’s know how we can eliminate those obstacles.

China’s robots represent an existential threat to the US, according to semi -health experts

by

“This is a call to action for the US and West. We are on the threshold of a non -linear transformation of The industrial societybut the basis on which US is intense is unstable. Automation and robotics They are going through a revolution which will allow the total automation of all strategic and manufacturing industries. These Smart robotic systems They will be the first industrial piece that will not be complementary, but completely additive: work 24/7 with a performance higher than any human being (…) “. “Currently the only country positioned to capture this level of automation is China, and, if it achieves it without the US to follow the same path, the expansion of production will be exclusive to China, which will represent an existential threat to the US when it is overcome in all its abilities.” This text is signed by Dylan Patel, Reyk Knuhttsen, Niko Ciminelli, Jeremie Eliahou Ontiveros, Joe Ryu and Robert Ghilduta, six experts from SEMIANALYSIS. This American consultant specializes in the analysis of the semiconductor industries and the artificial intelligence (AI), and their studies are usually reasonably accurate. China’s technological and scientific development rhythm is overwhelming The lines of the semi -toalysis report that I just mentioned contain a lot of interesting information, but without a doubt the most forceful reflection of how many they put on the table is none other than the great capacity that China has in the technological, scientific, and, of course, economic. It is evident that they all go hand in hand, but this attention call will hardly take off the US administrations and Western countries. We can be sure that their slow reflexes is not caused by ignorance. China has the necessary capacity and resources to dispute its world leadership position to the US The US government led by Joe Biden openly recognized the document that collects its National Security Strategy October 2022 that China has the necessary capacity and resources To dispute the US Its world leadership position. The social, economic, military and technological development that the country led by Xi Jinping has experienced during the last two decades supports this conclusion. The following literal extract of this document reflects very clearly why the US government considers China a threat: “The Popular Republic of China (RPC) is the only competitor that has both the intention of remodeling international order and, increasingly, the economic, diplomatic, military and technological capacity to do so. Beijing has the ambition to create a wide sphere of influence in the regions of the Indian and the Pacific, as well as to become the leading world power.” These lines perfectly condense the background history that has triggered The international situation in which we are. Anyway, as we have just seen, semi -health experts emphasize the development of robotics and automation technologies in China. In their text they do not speak of the possibility that the country of Xi Jinping use Robots for military applications; What they maintain is that this technology represents an existential threat to the US Due to its ability to radically transform the industrial model of which not only the country currently led by Donald Trump, but also Japan, South Korea, Taiwan or a good part of European countries, among other nations. At the current situation, staying behind in strategic field like this is not an option.

The European megafauna is officially back. And experts warn: we will have to get used to

by

European biodiversity is constantly changing. While some species disappear from the continent, others arrive in the form of invasive exotic species. There are also those that return to the wild areas of the continent thanks, at least in part, to the efforts placed in their recovery. However, these efforts are not always welcome throughout the world. The return of some animals, and conservation policies that try to protect them from hunting and other threats have been a source of controversies that resurface periodically in the media. We have a recent example last summer, when the Court of Justice of the European Union (TJUE) was pronounced twice against lobos hunting. The first It was after a decision of the government of the federated state of Tyrol; the second, for Back a Castellanoleonese rule. The wolf’s hunt is still vetoed in Europe while its state of conservation is unfavorable. 2025 could see this change in it status of the wolf. A few months ago, the committee responsible for supervising the Berma Agreement accepted the proposal for the change in criteria. This may imply that in the coming weeks we see changes. In Xataka Send 167 wolves to the highlands to fight the deer: the crazy plan of Scotland to save their forests Like the wolf, the bear has also starred controversially for its conservation. Recent estimates about the population of brown bears in the Cantabrian mountain range speak of about 400 copiesan increase with respect to populations three decades ago where the estimate placed the number of copies Below 100. Again, the return of this animal to the Spanish mountains has generated certain risks. Problems that can affect both people as To the bears themselves. Perhaps we can also find examples of less controversial reintroductions, such as that of the Iberian lynx. Since the 90s, the native feline has been leaving the situation that almost led to extinction. The lynx are predators and There are no lack of cases in which these hunters have chosen farm animals like their prey. Problems of this type are not even limited to large or small predators. Even the proliferation of rabbits has been seen with alarm from part of the agricultural sector, proof that the relationship between humans and natural environment is not always easy. And what do we do? Find ways to manage coexistence between carnivores (Carnivorathe diverse taxonomic group that includes mammals such as wolves and bears, but also seals, hyenas and felines) has been the issue of a recent study prepared by a European group of researchers and Posted in the magazine People and Nature. The study deals with how to address interactions, how to plan and organize the efforts of local communities towards coexistence with these animals. To do this, it emphasizes the role of local communities when guiding how this relationship should be, communities whose forms of knowledge “are too overlooked and marginalized.” They attract attention, yes, about an important detail, which people are really part of these “local communities.” “This research is especially important in the pastoral areas of Europe, where populations of great carnivores such as the wolves who is ‘local’ here? What constitutes the ‘local knowledge’? And what can this knowledge contribute to the management of carnivores? ” explained in a press release Hanna Pettersson, co -author of the study. {“Videid”: “X8SPB12”, “Autoplay”: False, “Title”: “The penguins are extinct and are not the animal you think”, “Tag”: “Webedia-Prod”, “Duration”: “235” } New research has been published in the days prior to the United Nations Biodiversity Conference held between today and Thursday 27 in Rome. This is precisely the debate forum in which issues such as this may be debated by the international community, not only at European level. In the face of the conference and the search for new solutions to coexistence between humans and carnivores, the team responsible for the study proposes an approach based on the conservation of spaces. To do this, it suggests the investment in “local practitioners networks” in charge of coordinating this local knowledge in the production of “strategies adapted for coexistence”.

How to change all our passwords according to three cybersecurity experts

by

Passwords have become an essential part of everyone’s digital life. In combination with other verification methods, They are the entrance door to almost all the digital services we use. We need them to make online banking efforts, but also to log in to email accounts, social networks, streaming platforms or online stores. Like house keys, passwords must be well protected to avoid dislikes. But sometimes it is not enough to save them well: there are times when they should change them or reinforce security with additional methods. The question is when. In Xataka we have asked three cybersecurity experts to clear doubts and know what decisions we should make. The problem of security gaps Francisco ValenciaCEO of the Computer Security Company Secure & Itopened the conversation with a blunt phrase: “The user has to think that passwords Sooner or later they will expose themselves” What the expert tells us is relevant, because we usually navigate this increasingly digital and interconnected world without being completely aware of the threats that surround us. Valencia explains that the exposure of our passwords, or what is the same, that they have been committed or revealed, can occur in two ways: that they rob us directly or subtract them from the services where we have registered them. When we register in some online service, this should protect our authentication data, however, as the specialist points out, it is often not so. To illustrate it, the interviewee remembers Yahoo’s case. In 2013, with Marissa Mayer in front, the company starred in a colossal security failure, considered by many as one of the largest in history, which exposed the data of 500 million accounts. The platform “It seemed reasonably safebut the passwords were stolen and informed the users years later, ”he says. “The user has to think that the passwords sooner or later will be exposed.” Alejandro BotterCyber ​​Security Evangelist of Check Pointreveals that “it is increasingly common for a data gap to present.” The expert indicates that these types of scenarios where there is some type of data exfiltration can occur in any field, from a hotel to a bank, although the latter should, in theory, have more robust security measures. While the leaks of our passwords by those who are trusted are a reality, Botter warns that the most traditional security threats, those in which we deliver our passwords involuntarily, are still very present. “We might access a site that was not correct And let’s leave our password, or that the device will be infected, ”he explains. It also emphasizes that awareness is essential to understand that cybercounts not only pursue important objectives, but any white can be. “Many people say: ‘Where will my email be? I don’t think it’s my turn. ‘” In this regard, he mentions that tools such as “Have I Been Pwned? “The reality of information leaks account very palpably. Asked about whether we should trust the page created more than a decade ago by the Australian security consultant Troy huntBotter highlights the positive aspect of the platform, but says that “there is debate about it”, and that we do only email We are providing information that “it is achieved in different ways on the Internet and that is not so complex to achieve.” What are we wrong with our passwords? Adrián Arrow, cybersecurity technician INCIBE- Certhe tells us that “for years, passwords have been the main method of access to our accounts, but also represent one of the greatest security risks.” The specialist of this Spanish Institute adds that “the reality is that most users reuse keys, choose weak combinations or fall into phishing attacks.” Valencia supports this perspective with a practical example: “When we make an audit and, for example, we find a password of a person’s tennis club, it turns out that looking for password password We see it in another pile of sites because that same user has put the password on all sides. And that makes criticism even greater. ” The CEO of Secure & It emphasizes that one of the most critical problems of password reuse is that, generally, they end up leaking by the weakest link. Since the user has used the same set of characters in other services, many times together with the same email address, he ends up exposing all his accounts in a way that would not have occurred in case of using different passwords. “The reality is that most users reuse keys, choose weak combinations or fall into phishing attacks.” “Passwords cannot be the same in all sites. People many times have two passwords, the easy and difficult, and It turns out that it puts the difficult at the bank And something else and the easy thing in everything else. The password cannot be the same, it has to always be different, it has to be random, it has to be difficult to remember, etc. ” This, he explains, will force us to use a password management tool The interviewee adds some quite useful examples: “Knowing the exhibition, if they steal a password, they will exclusively attack the service where I put it. The Facebook password steals me, it will only affect Facebook, but not anything else. Until now the gravity is that if the Facebook password is stolen, it turns out that it is also for my bank and therefore the exhibition is much worse. ” Users usually ask if using a password manager is a good idea. Arrow, from Incibe, explains that “password managers are one of the safer and practical tools PARA store and manage our access credentials ”, and highlights some of its advantages. It lists that they not only serve to store passwords, but are also useful for generating them. “While no technology is infallible, a well -designed manager offers much more security than scoring paper passwords or trying to remember them all. Currently, there is no manual alternative that is so safe and practical. There are cloud and local versions (without connection), but … Read more

They were nuclear weapons experts

by

The Government Efficiency Department (Doge) led by Elon Musk does not supply say goodbye to all officials That, according to the greatest fortune of the planet, there are plenty of administration. In his last intervention, the Doge agents They fired about 350 officials of the Department of Energy. What they did not know is that they were sending specialists at home nuclear eyelet assembly and control of weapons and nuclear waste. Nuclear layoffs. According to published CBS News, Doge employees thought that last Thursday they were saying employees in the test period or simple administrative department of the Department of Energy, without stopping to ask what their work really was. However, hundreds of federal employees who work in the United States nuclear weapons programs also received their dismissal notification. According to sources of The Associated Press Near to the Department of Energy, up to 350 employees of the National Nuclear Safety Administration (NNSA) were dismissed unexpectedly. Some of them lost access to their email before being formally notified or could not access their job with their credentials. The NSA is the entity responsible for managing the country’s nuclear weapons, among other crucial responsibilities. Specialists in nuclear eyelets. One of the facilities most affected by Doge’s layoffs was the Pantex plant, near Yellow (Texas), which suffered a 30% template cut without prior notice. In this plant, employees are dedicated to the reensamblage of nuclear eyelets, a high specialization task that requires the highest levels of security authorization. The agency’s interim director, Teresa Robbins, sent a statement to the dismissed employees annuling the dismissal order, has caused enormous confusion throughout the agency. However, 28 officials were not readmitted. “This letter serves as a formal notification that the termination decision issued on February 13, 2025 has been terminated, with an immediate effect,” said the memorandum obtained by AP. Dismiss first, then ask. Given the nature of these dismissals, the discretion used by the department led by Elon Musk, when saying goodbye to officials without previously analyzing the scope of their work, has been revealed. That action pattern carries the Elon Musk’s unequivocal seal. He did it With the Development Department of the Tesla Supercores, and then hire them again because the service had been paralyzed. He did the same With the Twitter moderation department Chaos in a strategic department. “The people of Doge arrive without having the slightest idea of ​​what are the responsibilities of these departments. They do not seem to realize that, in reality, it is more about the department of nuclear weapons than the department of energy,” said Daryl Kimball, Executive Director of the Arms Control Association. A senior NSA official, Rob Plonski, also expressed concern about dismissals in a LinkedIn publication: “This is a crucial moment. We must decide whether we are truly committed to leading on the world stage or if we content to undermine the same systems that ensure the future of our nation.” Plonski warned that “cutting the federal workforce responsible for these functions can be seen as reckless in the best and adversely opportunistic in the worst.” CONSEQUENCES FOR THE NUCTILE FORCE OF US. The layoffs and subsequent readmission of the employees of the Department of Energy have planted the seed of uncertainty among those officials, and some are rethinking whether to work back in the agency. “The main impact was a blow to the morals and trust of the employees who were dismissed,” assured to CNN A nearby source. Many of them have dedicated their entire career to nuclear programs, becoming a valuable asset of knowledge in this area. These layoffs have only come to aggravate the constant loss they had already suffered after a recent wave of retirement, which has already meant a loss of qualified talent in this department, just when the US is carrying out an important effort of Modernization of nuclear weapons of 750,000 million dollars. Edwin LymanDirector of Nuclear Energy Security of the Union of Concertned Scientists (UCS), explained to CBS News that layoffs could “alter the daily functioning of the agency and create a sense of instability about the nuclear program both in the US and abroad. That can only benefit the adversaries of this country.” In Xataka | A government “Extremely Hardcore”: Elon Musk is applying to the US the same recipe that has applied to all its companies Image | ThE White HouseUnited States Department of Defense

38% of its experts have formed in China

The Government led by Donald Trump is determined to make the decisions that are necessary to sustain US leadership in the scope of the artificial intelligence (AI). This technology has a critical value for the great powers. In fact, The dispute over world supremacy that China currently maintains and the US turns largely around it. And he does it because his applications are presumably unlimited. The AI ​​is already being used for medical diagnosis through image analysis, to design new drugs or to produce new materials, Among many other possibilities. But it can also be used to develop very sophisticated weapons. Last week James David Vance, the US vice president, He spoke a speech During the last day of the summit dedicated to AI in Paris in which he expressed very clearly what is the position of his country in this area: “The most powerful artificial intelligence systems are built in the US with chips designed and manufactured in America (…) USA is the leader in AI, and our administration plans to keep it like this. We have all the components throughout the entire chain of Value, including the advanced semiconductor design, avant -garde algorithms, and, of course, transformative applications. ” This is a declaration of intentions, although the US does not have everything in its favor. More than a third of the US experts come from China A good part of the companies that have developed advanced AI models are American. Openai, Google, Microsoft, Anthropic, Meta, IBM, Chere or Xai, among others, are from the US. However, the knowledge that sustains innovation in the country currently led by Donald Trump is not exclusively in the hands of US researchers; Chinese scientists are making decisive contributions to the US ecosystem. In the US there are more Chinese experts in AI than professionals with a strictly American origin According to a group of researchers from the Paulgo Institute in Chicago (USA), 38% of AI experts who develop their professional career in the US have trained in Chinese universities. In fact, this American institution has concluded that In the US there are more Chinese experts in AI than professionals with a strictly American origin. This, According to Nikkei Asiasome experts in the industry concern due to the possibility that China decides to repatriate their students and researchers from the US to reinforce their AI industry. Some of the best centers dedicated to the science and technology on the planet are in China. The Tsinghua University of Beijing, the Jiao Tong University of Shanghai, the Zhejiang University of Hangzhou, the University of Science and Technology of Hefei or the University of Technology of South China, in Canton, are just a few. All of them have something important in common: they are world reference centers in technology, innovation and applied science. And many of his students are working in the US. At the current situation It is understandable that some American experts are concerned about the possibility of losing these qualified personnel.

Spring is just around the corner and, we like it or not, this means that we can start drawing conclusions. The first is that every minute that passes is more likely to finish winter without seeing any “cold wave.” And that is not even what most worries meteorologists. Because the real problem is that it would be the second consecutive winter without cold waves and a third would be at hand. With all that this entails. Isn’t it a bit precipitated to give the winter for dead? The truth is not. Although this week an extremely cold mass of air will cover a good part of Europe, Spain will escape from it. And on March 1 (which is when climate spring begins) is very close to be able to house realistic hopes about an extreme cold episode. And, in the background, what we are going to see this week summarizes very well what has been going on two winters: we have not suffered powerful cold irruptions. They have all stayed north. It is a story that is repeated again and again. But it’s not so weird either, right? That is true. The cold episodes become more and more rare in Spain. In fact, this January can only be described as very warm (Although we have suffered a handful of cold nights). A example that Roberto Granda puts It is that of Molina de Aragón. The average minimum between 1991 and 2020 is -3.3º, but this year it has been at -0.3. The data speak for themselves. In the end, As I pointed out A few years ago our partner Javier Pastor, “is not that it is very cold now, it is that we do not do it because it is no longer so common.” With this in mind, the question begins to be … how long can this last? “Unusual and worrying.” That is, what would happen if the winter of 2026 is still on the same line? The answer, According to Samuel Biener de Meteoredit is summarized in those two words: “Unusual and worrying.” Because we have documented other consecutive warm winters (those of 97 and 98, those of 2000 and 2001 or those of 2023 and 14); But we have not seen three consecutive yet. And we know it will arrive. Because, As Biener points outwarm winters are being increasingly frequent. It is a matter of time that we fit three. And what is the problem? More than a problem (that too), we talk about a fear: that warm winters stop being an anomaly and become the norm. That change is a large-scale disruption of the country’s socio-ecological system. It is no accident that, a few months after the drought, The data begin to be so bad. Again. Not only climatic pressures They hit us stronger than everthe thing is They don’t let us replenish. And that will lead us to the edge of the precipice again and again. Yes it’s true. The current climate is full of paradoxes: Historical ice minimums live with snow maximumstudies on The weakening of the Gulf current They coexist with others that point to nothing has changed in substantial terms and thus a long etcetera. However, there is something that Yes we know is that we are vulnerable And if we don’t prepare ourselves, Let’s be much more.
