He has also sued the European Commission for tariffs, according to Politico

by

Elon Musk star in a confrontation with the European Commission (CE). On this occasion, the conflict does not revolve around alleged breach of the Digital Services Law (DSA) with Xbut the focus is on tariffs affecting the electric car. Political points out that Tesla has filed a lawsuit against the executive arm of the community block before the Court of Justice of the European Union (TJUE). The automotive company adds, in this way, to the legal actions initiated by the Chinese giants Byd, Saic and Geely against the commission. The American renowned explains that the demands aim to leave without effect Compensation rights, that entered into force in October last year. If the ruling is favorable for the plaintiffs, they could initiate a loss claim. Tesla’s case against the EU It should be noted that Tesla has not made comments about it. The information comes from two sources from the demanding sector, which have preferred to remain anonymous. Politic adds that the commission has approximately two months to prepare your strategy of defense against the multiple cases presented in Luxembourg in recent months. Although there have been no reactions on the demand for Tesla, the Commission has issued public comments regarding the demand of Chinese manufacturers. Olof Gill, spokesman for Economic Security, Commerce and Financial Services, said they were prepared to respond to attempts to challenge the courts, making it clear that they have no intention of yielding to the pressures. As we have indicated above, the good course of the case could allow the plaintiffs to request compensation for the money paid in compensatory rights. Now, Tesla has been The least affected manufacturer. The American company has production plants in different parts of the world, although Model 3 that are marketed in the European market come from the Shanghai gigafactoría. MG4 Electric Tesla, who actively collaborated in the anti -subvent research of the community block, received a 7.8%”tariff”, the lowest among all manufacturers. Byd’s was 17%, Geely’s of 18.8%and SAIC’s reached 35.3%. In all cases, these compensatory rights are added to the 10% rate that the EU already applies to the importation of vehicles, a lien that has been in force. Unlike Tesla, which has the Berlin gigafactoría To manufacture the Model and And batteries, Byd still has no factories in Europe, although it is already planned to open one in Hungary. For its part, Saic, that Markets MG cars like him MG4 ElectricNor produces vehicles inside the EU. Instead, Geely, who acquired Volvo in 2010, does have production lines in Sweden and Belgium. Manufacturers that produce electric vehicles inside the EU can dodge tariffs. However, as we have pointed out, none of the Chinese companies affected by this anti -subvention measure manufactures vehicles in European territory. Now it’s time to wait to see what effect the demands will have. They may not achieve an absolute victory, but they could negotiate better tariff conditions.

‘Final Fantasy VII Rebirth’ on PS5 or on PC? We talked to the director of this one to clear the doubts

by

He Remake of ‘Final Fantasy VII’ In three deliveries it is one of the most ambitious projects that Square Enix has faced throughout its history. A Reformulation of the classic RPG that recovers his legendary characters and that unforgettable story through which everything happened, but that adapt your mechanics to the new times and open your world admirable. A year ago the second installment, ‘Final Fantasy VII Rebirth’, arrived at PlayStation 5, and this week finally lands on PC. We have had the opportunity to talk to the game director, Naoki Hamaguchi, so that this renewed version for PC works and what we contribute to what we already saw in console. And of course, our first question could only be what it feels like to see legendary characters in the world of PlayStation on computers and what personal relationship has with the franchise. Hamaguchi tells us that he has “been a fan and player of ‘Final Fantasy VII’ ‘when I was a child. If I look back now that more than twenty years have passed, I am still surprised by the fact of having developed’ Final Fantasy VII Remake ‘ , ‘Rebirth’, and now the third and last game of the trilogy. “ But let’s enter into technical level, Does this version for PC elements contribute to the game that were omitted in consoles? Hamaguchi tells us that they have varied, above all, “the rendering parameters, so that they can adjust to graphic quality and the processing load in a more flexible way. Specifically, ‘Final Fantasy VII Remake’ kept LOD’s gradations limited ( level of detail) of the modeling, with a few different degrees. what keeps stable the FRAME RATE“ This novelty is important to adapt to all types of PCs: “This allowed us Enjoy a stable game that maintains a good level of quality, and if you have a team that meets the requirements of the ultra level, you can enjoy a graphic quality even higher than that of the PS5. Steam Deck And we have been verified by Valve. “ More than technology So, is the technical part as relevant to this PC adaptation? Many times, computer ports stay in mere technological muscle exhibitions and we wanted to know if this is also the case. Hamaguchi clarifies: “It should say that the highest resolutions, the highest frame speeds and the improvements in the quality of resources are part of the appeal of the PC version, but what I really want people to see It is how We have redesigned the lighting with respect to the PS5 versionwhich has greatly improved the charts of the characters. “In fact, these changes will follow the reverse path:” PS5 players have asked us to update lighting as on PC, and although I cannot promise anything definitive by the moment, we are studying possible updates. “ Another of the essential differences between the console and PC version is in the controls, of course. Hamaguchi also enters that matter, telling us that the game “has many different mini -games, so we had to think a lot about how to adapt the configuration of the keys. For example, the minigame to touch the pian form that they imitate the keyboard of a real piano. “The PS5 version continues to offer you a complete and satisfactory experience, but it is true that the PC version is The best way to enjoy ‘Final Fantasy VII Rebirth’ with the highest graphic quality Possible, “concludes Hamaguchi. Now the decision is in the hands of the players: Punta technology or classic formats? We already have something to think about until the arrival of the third installment.

In full era of extreme heat waves and saturation, Spain has found an engine to boost its tourism: winter

by

If a while ago they had asked us (to you, to me or any) where we had to pass the vacations, we would have responded that Bali, Italy either Barcelonadepending on the tastes and budget of each one. What is almost certain is that wherever we imagine we would imagine in short sleeve, wearing shirts, with cap and sunglasses. Normal, right? Except for the Snow loversvacations has always been synonymous with summer and high temperatures. In a Spain that deal chronically with Heat waves, droughts and saturation Of his great island destinations and the Mediterranean coast that is no longer so. On vacation with a scarf. With the sector in record levels and increasingly foreigners in hotels, in Spain the flow of tourists grows throughout the year. In the cold months. And of course in the warm, the most associated with the offer of “Sun and Beach” that so well worked for years to the hospitality industry. The INE data and independent studies They show however that more and more travelers are, when planning their vacations, they look for dates in winter. What do the figures say? That in Spain tourism not only grows during the summer months. He also does it in winter. And at a good pace. Between October and December 2024 The INE counted 24.5 million travelers in their hotel occupancy survey, 35% more than during the same months of 2014 and 72% higher than the same balance of 2004. Between January and March the flow of travelers was 20.6 million, which also leaves increases of 43 and 74%, respectively. Growing more in percentage terms is “easier” when you start from low data, so it is normal for tourist increase percentages to be more bulky during the cold months than summer. Even so, the differences between them are interesting. In 2024 the INE registered 38.1 million tourists between July and September, 25% more than a decade before and 56% above 2004. In both cases they are increased increases than those of winter. The cold weight of the cold. The observatory shows that despite the Increased tourists That Spain has registered over the last years, winter has not lost weight in the sector. On the contrary, they have been reinforced as a holiday period. If in 1999 the coldest months (December-February) brought together 21.7% of the total number of travelers counted by the INE throughout the year, in 2024 that portion of the cake was somewhat larger, of 22.2%. It is not a great increase, but significant. In the specific case of foreign tourists, arriving from other countries, the increase was even greater: the contribution from winter to the annual balance passed in that case from 18% of 1999 to touch 20% in 2024. The data is extracted from the Hotel occupation survey of the INE, with which other types of accommodation exclude. When do you travel? A few days ago the economist Ángel Talavera shared in x Another study, with cross data from Oxford Economics and Aemet, in which it is appreciated how tourism grows at a good pace in winter and autumn, even more than during the “peak” summer weeks. Reading is the same: in a stage of general tourism growth, new travelers who move in Spain do not focus only on the warmest months. They also look at the scarf months. In favor of the flow of tourists in winter he has played The bet of some Spanish cities for Christmas, especially cities such as Madrid, Badalona or Vigo, which have made it one of its main tourist claims. This year the Galician city even launched a promotional campaign with posters in New YorkLondon, Rome or Paris in which he presumed from his Christmas decoration. Not everything is positive factors. Winter tourism has had to deal with The crisis of skiing stations, conditioned (and in many cases forced to reinvent themselves) Before snow shortage and “lightning” seasons. Click on the image to go to Tweet. Great ally to great threat. The data collected by the INE and Oxford Economics are interesting because they are framed in a broader phenomenon and that over recent years have analyzed other organisms, such as European Travel Commission (Etc) or Caixabanck Researchsand that can also be followed with the help of The international press: The heat that for decades served as an ally to the Spanish tourism sector and made Spain a destination coveted by citizens of countries more north now threatens to become an enemy. The reason is simple. Between heat waves and chronified droughts, added to the saturation of Great destinations of the Mediterranean or the Canary Islandsforeign travelers have begun to look with more temperate alternatives. Rethinking the holidays. The data From etc. they are revealing: 33.7% of Europeans avoid places where they are exposed to extreme meteorological phenomena, such as heat waves, and 17.3% directly discards the regions in which mercury can rise too much during Your trips. Moreover, 8.5% of respondents recognize that they have begun to change the months in which they travel. And etc is not the only one to detect that trend. The United Kingdom Tourist Operators Association (ABTA) suggests That the months of “middle season”, such as October, May or June (either icy or achicharrantes) have become the most popular among the British who plan a vacation abroad. One and no more. The relationship between the thermometer and tourism was analyzed a while ago CaixaBank Researchs in A broad study in which he slid another interesting idea: foreign visitors who have to live a heat wave during their vacations are less likely to repeat destiny. To be more precise and in the case of Spain, its willingness to return falls from 14 to 12.1%. And that is the average. The percentage varies between nationalities. Americans, for example, do not seem willing to sweat during their vacations. Among those who have touched a heat wave in Spain the inclination to repeat fate falls 42.5%.

salary is one of the main culprits

by

Bill Gates once said: “You have to enjoy what you do every day.” However, one in three Spaniards says they are not satisfied with their current job. An insufficient salary, too long hours or lack of recognition are the main arguments for this discontent. The hospitality industry is burned. According to data from a study carried out by the job offers portal Jobatus.es that has published Newsworkonly 28.7% of Spaniards are completely satisfied in their job. However, this satisfaction varies by sector. The sector with the happiest and most satisfied employees is technology, with 40.2% satisfaction among respondents, followed by Energy and environment with 38.9% and Education with 34.5%. The professionals with higher rates of dissatisfaction are those in the hospitality industry, of whom only 19.7% claim to be comfortable in their work, followed by employees in the retail sector with 22.4% and the construction sector with 23.1%. satisfaction. The salary is not convincing. One of the most repeated arguments to explain this job dissatisfaction is receiving an insufficient salary, where 53.5% believe that they receive a lower salary than they deserve. The second reason for job dissatisfaction is work time. commuting to workin which 45.6% say that they spend too much time getting from home to work, and long for the times of teleworking or would like a job closer to home. The work environment within the company is also a cause of dissatisfaction since it contributes to raising stress levels. 28.3% of workers claim that they do not receive enough recognition, despite making an effort to do their job well, while 18.9% attribute their dissatisfaction to a toxic work environment that demotivates them. The limitations to ascend and the imbalance between personal and work life are also reasons for dissatisfaction for 17.4% and 14.7% respectively. Dissatisfaction depends on where you live. Data from Jobatus.es reveal that respondents living in Navarra were those who showed the highest satisfaction with their work with 42.3%, followed by the Basque Country with 39.8% satisfaction among its workers. At the opposite extreme is Andalusia, which with 21.5% is the autonomous community with the greatest job dissatisfaction, due to lower salaries and longer duration in employment contracts. They are followed by the Canary Islands, with 23.1% employee satisfaction, and Extremadura with 24.3%. Salary increases. The data points to salary as the main obstacle to job satisfaction, despite the fact that economic data indicates that companies have raised salaries by an average of 3.5%, according to data from the consulting firm KPMG. The Government has also contributed to maintain purchasing power of salaries by increasing the Minimum Interprofessional Salary up to 1,134 euros in 14 payments. However, the increase in prices and inflation has made the shopping cart absorb the salary increase, diluting the perception of that increase.

end reclining seats

by

We have a love hate relationship with reclining airplane seats. They are great if you want to nap more comfortably, but if you don’t and the passenger in front of you does, that can be quite annoying. The airlines know this, and are considering their disappearance forever. These seats also impose other problems on airlines. They are more likely to break down, but they also add weight to the seats, something that does not help final fuel consumption. Some airlines don’t even offer that button on coach seats, while seats began to appear in the late 2000s.”pre-reclined“, lighter and that fixed the backrest at an intermediate angle: neither completely upright nor completely reclined. British low-cost airline Jet2 was one of the first to use them in 2009, and British Airways also began using them later for flights lasting less than four hours. Ryanair he charged them directly in 2004 as a measure to make better use of space. The airline then commented how this would allow it to save about two million euros a year. And when it doesn’t try to save for it, it tries to make its users pay more with debatable ideas. Like for example, travel standing. There are many other cases: in 2019 Delta reduced the degree of inclination of its seats from four inches to just two inches for economy class, and from 5.4 inches to 3.5 inches for first class. American Airlines, United Airlines and Southwest Airlines They also limited reclining to two inches on domestic flights There are a couple of clear additional factors in the partial or complete disappearance of that option. The first, that airlines can eliminate the possibility of choosing reclining seats in economy class and charge those seats as an interesting extra to raise the price of tickets. After all, the future seems prone to the appearance of “premium” middle class seats. Reimagining the airplane seat The other, of course, is space savings. According to CNNif an airline can save 2.5 cm of space per row, that will be equivalent to about 76 cm on a Boeing 737 or Airbus A320. Or what is the same: a whole extra row of seats. There are several attempts to revolutionize the seating arrangement. For example, with double height seats like those devised by the young Spanish entrepreneur Alejandro Núñez Vicente. There are also curious designs that they reposition the middle seatusually the worst rated when traveling by plane or unique ideas —or maybe terrible— like that of the inverted seats. For now, yes, airlines are betting on pre-reclined seats. This is indicated in the aforementioned CNN article, which gives the example of the manufacturer Recaro, one of the firms that is taking advantage of the trend to equip airline planes with their seats. To find out the degree of inclination – in Recaro it is light and ranges between 15 and 18 degrees – the concept “max pax” is used used by industry. That is, the maximum count of passengers that each plane is certified to be able to transport. In an Airbus 321neo, for example, it is up to 244 passengers if everyone traveled in economy class, but when the front part is used for the traditional first and business class seats, the seats are considerably reduced and drop below 150 passengers. . Even so, traditional seats are “slimming” in parallel with the rest of the techniques. It changes the structure and becomes thinner right in the part where travelers have their knees to allow them to be more comfortable. That extra space for the knees, of course, is usually another argument to raise the price of the ticket. The advantages of eliminating reclining seats are obvious on short-haul flightsbut things change with longer flights. Meanwhile, if you are going to travel by plane, it may not be a bad idea to let the passenger behind you know if we are going to recline the seat.

Even Sony, creator of the format, abandons it

by

No one is aware that the physical format is experiencing a real debacle: more and more player manufacturers have been abandoning the format. panasonic, sony and Oppo They stopped doing it in 2018, Samsung in 2019 and LG in December 2024. But The last one who announced his abandonment has something symbolic: it is Sony, inventor of the Blu-Ray format, who has announced that it is stopping manufacturing several physical formats, after announcing a series of layoffs at its factories. In addition to recordable Blu-Rays, in February it will stop manufacturing MiniDiscs and MiniDV tapes, formats that were already clearly obsolete. The company has confirmed it in a message on your website where it also makes it clear that there will be no models that will succeed these formats, so it is not that it is seeking to evolve what we have already known, as Blu-Ray succeeded DVD. Once stock is exhausted, they will not be restocked in stores. This is a commercially logical decision that will devastate collectors and that destroys the intention of other brands, such as LG, to return to manufacturing players if the winds sounded favorable in the future. With this notice from Sony, the format is effectively adjusted, since We are not talking about a mere manufacturer of record playersbut from one of the most important manufacturers of the discs themselves. Significantly, apart from support the manufacturing of the new formatSony was its main distributor thanks to the expansion of Playstation consoles. Both the PS3, as well as the subsequent 4 and 5, included a Blu-Ray reader, and were decisive in establishing not only the format in the video game industry, but also in the film industry. Also very significantly, it is in recent years, when the format has begun to decline in favor of digital, both Microsoft and Sony have announced versions without a disc reader of their consoles. Playstation 5 Pro has been the first console to be launched without a version with disk readerwhich must be purchased separately.

In 1930, Japan sent rabbits to an island to test chemical weapons. A century later something is killing the creatures

by

In the quiet region of the Seto Inland Sea, three km off the coast of the Japanese city of Takehara, in Hiroshima prefecture, lies Ōkunoshimabetter known as Usagi Jima or Rabbit Island. Today, the island is famous for being home to hundreds of wild rabbits that roam freely fed by tourists and living without predators. However, behind this idyllic image hides a dark past. In World War II the island was a secret center for the production of chemical weapons by the Imperial Japanese Army. The rabbits are “children” of that experiment, and now they are dying. A secret from the past. During the 1930s and 1940s, Ōkunoshima was the epicenter of the manufacture of so-called mustard gasphosgene and other chemicals used by Japan against Chinese soldiers and civilians. Estimates suggest that These toxic agents caused around 80,000 deathsand to test the effects that those experiments had a small rabbit fauna was launched onto the island which was increasing in number. To give us an idea, the strategic importance of the island was such that was removed from Japanese maps to keep their activities secret. Since then, there has been speculation that the number of current rabbits are direct descendants of those used in the poison gas testing experiments at the island’s military laboratory. According to Professor Ellis Kraussfrom the University of California, San Diego, most of the test rabbits were slaughtered by American forces after the Japanese surrender in 1945, but those that escaped their fate transformed the place. Rabbits and more rabbits. Therefore, and given that it seems unlikely that there are surviving creatures that inhabited the place during the military era, the question has always been to discern which are direct descendants and which are not, in which case, where the hell did they come from? One of the most accepted theories suggests that, in 1971, a group of students released about eight extra rabbits on the island. The absence of predators, the prohibition of hunting and the inability to keep pets such as cats or dogs have allowed the population to grow uncontrollably until it reaches approximately 1,000 individuals today. The impact of tourism. Although rabbits have made Ōkunoshima a very popular and tourist destinationthe increase in visitors has generated serious environmental and animal welfare problems. As? The practice of feeding rabbits inappropriate foods, such as cabbage, has led to digestive problems and nutritional deficiencies, reducing their life expectancy to just two yearsmuch less than in natural conditions. Besides, feeding dynamics are inconsistent: On sunny days and holidays, tourists provide large quantities of food, while on rainy days or out of season the animals are left without supplies, facing a shortage of resources, since the island’s vegetation has been devastated by overpopulation. And if all this were not enough, a mystery surrounds the island these days. They are dying without explanation. According to the Japanese authorities, More than 70 rabbits have died in circumstances not yet clarified. Last Thursday, Police arrested a man identified as Riku Hotta25, on suspicion of having kicked at least one rabbit on the island. The animal reportedly died shortly after the incident, prompting authorities to investigate whether there is a connection between Hotta and the discovery of those 77 carcasses. between November 26 and January 12. The bodies of the 77 rabbits were apparently found with unnatural injuries, such as broken bones, which has further sparked concern among authorities and tourists. Possible causes of death. As we said, despite the arrest, authorities have not yet determined a conclusive cause for the death of the creatures. However, Japan’s Ministry of Environment has indicated that Possible reasons could include: Infectious diseases, which could have spread due to the high population density and irregular diet provided by tourists. Adverse weather conditions, especially the cold of winter, could be affecting the rabbits, whose food depends largely on occasional visitors. Human factors, such as acts of cruelty or negligence, since there have been cases of visitors not following animal care guidelines. In this regard, and given that the suspect (Hotta) is not a resident of the island, but of Otsu, in Shiga prefecture, located halfway across the country, it is being investigated whether he made sporadic visits to carry out said attacks. Meanwhile, the Japanese government has stressed that is working together with veterinarians and animal welfare organizations to identify the causes of these deaths, and does so while reinforcing surveillance and monitoring of the island to prevent future incidents. Future measures. There is no doubt that in a society like Japan, where pets occupy a prominent place, the incident has prompted calls to strengthen the island’s security and improve regulations to protect rabbits from possible aggressors. Options are being studied such as the installation of surveillance cameras, access restrictions and awareness campaigns to guarantee the well-being of the animals and the sustainability of the island as a tourist destination. The paradox of an island with a dark past. Rabbit Island represents a fascinating example of how a place’s military past can be transformed into a tourist attraction. Furthermore, it also highlights the challenges of human intervention (once again) in ecosystems. Image | Chih-Wei In Xataka | Japan sent the wrong creature to eradicate snakes from an island.

A study reveals which technological profile will be the most sought after and best paid in 2025: interface designer

by

Choosing the right career at the right time can be the key to building a successful, well-paying career. Like every January, the employment platform Adecco presents its Adecco IT & Digital Salary Guidewhich analyzes the technological professions with the greatest demand forecast and, more importantly, with the best remuneration for non-managerial positions. That is, salaries between 35,000 and 45,000 euros. A technological engine. According to data from the study, the technology sector in Spain is boomingand already contributes 24% to the national GDP, although this percentage also includes technological activities derived from the digitalization processes of other sectors such as agriculture, industry or the services sector. Adecco assures that the IT sector has generated 26,267 new affiliates in the last year, and the professionals with technological profiles They are the most demanded by companies, ranking among the top five in autonomous communities such as Andalusia or Catalonia. UX Designers, the most in demand. The Adecco study points out the rise in demand for specialized professionals in the design of digital interfaces or UX/UI Designers. This profile is responsible for designing the way in which users should interact correctly with digital products, whether web pages, application interfaces and even the use menus of digital kiosks or sales terminals. Adecco also highlights the high demand that Customer Experience Specialist profiles, SEO/SEM experts, Social CRM Managers or Traffickers who are in charge of planning online advertising campaigns will have. And the best paid. In the salary estimate that Adecco makes in its study, two business scenarios are considered depending on whether you are going to work in a large multinational company or in an SME, and it classifies it into three scales conditioned on experience in the sector in ranges of three. , five or more than 10 years. A user interface designer with more than 10 years of experience is estimated to have an annual salary of around 49,000 euros gross if he works in a multinational, and 45,000 euros per year if he works in an SME. The place of residence matters a lot. Something that the salary ranges estimated by Adecco show is that the salary amount is not only influenced by working for a large multinational company or an SME, there is also a large salary gap depending on the autonomous community in which the job offer is created. We have already mentioned that a UX/UI designer can charge between 40,000 and 49,000 euros per year depending on the type of company. That would be if the job were in Barcelona. In Madrid, the same position would lower its salary range to between 35,000 and 40,000 euros, while, in Murcia, the salary for that position would plummet to a range of between 25,000 and 20,000 euros. A substantial difference for the same professional profile. Web designer, in an SME and in Murcia. The worst salary option in the table is found in the salary profile of web designers who are going to work in an SME in Murcia. The data foresees a salary range of 18,000 euros gross per year, and 20,000 euros for web designers who work for a multinational in that community.

wants to overthrow Einstein’s special theory of relativity

by

Quarks, the elementary particles that make up the protons and neutrons of the atomic nucleus, are fermions. And electrons, too. There are several types, although physicists like to talk more about ‘flavors’: above (up), below (down), charm (charm), strange (strange), top (top) and background (bottom). The most frequent in ordinary matter are the up and down quarksalthough the one that interests us the most in this article is the top quark for a very interesting reason: it is the heaviest elementary particle that we can find in nature. An interesting note given that we are moving in the field of fermions: supersymmetry is a theoretical model of particle physics that proposes the existence of a hypothetical particle that is paired with each of the fundamental particles that we know. It seeks to explain the existing relationship between the bosonswhich have a spin with an integer value, and fermions, which have a half-integer spin. However, it is important that we do not overlook that it is a hypothetical theoretical framework that, therefore, has not yet been observed in nature. Not even experimentally. CERN has investigated whether the top quark respects the special theory of relativity The quantum mechanics and the special theory of relativity formulated by Albert Einstein constitute the heart of Standard Model of particle physics. Until now, this theory by the popular German physicist has stood the test of time undaunted, but scientists do not miss the slightest opportunity when it comes to putting it in trouble. And it is ideal because it is one of the most effective strategies when what is sought is to go beyond the solid walls of the Standard Model in the hope of develop new physics. Some specific models of string theory propose that at very high energies special relativity will no longer be valid. Lorentz symmetry lies at the very core of this model. Broadly speaking, this property justifies that the experimental results are independent of orientation and speed with which the experiment is carried out in the space-time continuum. It seems like a complicated concept, but if we think about it a little carefully, it is not so complicated. Be that as it may, what is really important is that so far all the experiments that physicists have carried out have supported Lorentz symmetry. However, and here comes the most interesting part, some theories, such as specific models of string theory, propose that at very high energies special relativity will no longer be valid and experimental observations will depend on the orientation of the experiment in space. -time. If so, the Lorentz symmetry would be broken. On paper, it should be possible to identify this break in the energy level that physicists work with in the CMS particle detector from CERN (European Organization for Nuclear Research). For months, CMS experiment researchers have meticulously analyzed the properties of the top quark pairs produced in the collisions at the LHC (Large Hadron Collider). And their result is very interesting: the production rate of top quark pairs remains constant even though the direction of the LHC’s proton beams and the average direction of the top quarks produced in the experiment change depending on the time of day due to the Earth’s spin on its axis. This means that there is no preferred direction in the space-time continuum capable of conditioning the production of top quarks. And, therefore, the Lorentz symmetry is still intact. And the special theory of relativity is still valid.

In full desert, Saudi Arabia is preparing its next great energy bet with the help of a partner: China

by

Saudi Arabia is facing a fiscal deficit Due to the expensive investments in projects such as The Line, which are part of their 2030 vision to diversify its economy. However, one part compensates for another, and that is that the Saudi country is focused in covering everything with solar panelsbut it has not taken into account until now where it could store energy. Short. Saudi Arabia has officially connected the largest energy storage system (Bess) in the world in Bisha, province of ‘Asir. The project has achieved a milestone in the country’s strategy due to a 500 MW/2000 MWh battery system. The operating company is Saudi Electric Company and uses advanced technology supplied by ByD. A larger initiative. The project, called Bisha Bess, is part of a broader initiative of the Arab country to further strengthen your renewable energy infrastructure. The nation is looking for more than half of its energy to come from renewable energiesso you have seen in storage the necessary component for this transition. Saudi Arabia has found that the batteries provide flexibility to the network and allows the integration of intermittent energy sources such as solar and wind. Apart from being part of the National Vision 2030 Plan, Bisha Bess is part of different large -scale storage initiatives.
