Low intensity magnetars are among the most unique objects of the cosmos. We are now discovering their secrets

The Magenetares They are among the strangest objects in the universe. The key characteristic of these neutron stars is their magnetism, but understanding the origin of this is not so simple. Explaining magnetism. Now a new study He has revealed That the origin of the magnetism of some magnetares, the so-called “low intensity”, is found in a phenomenon we call Tayler-Spruit dynamo. The new job, explain those responsible, resolves a mystery emerged more than a decade ago. Of low intensity. Magnetares are neutron stars, objects of great density that arise after the outbreak of some supernovae that give the death of large mass stars. These objects are characterized by their magnetic fields although, as we have discovered in recent years, these fields are not always comparable. Low intensity magnetares objects have between one and 10 tera-gauss (between 0.1 and 1 giga-tesla), which is one or two orders of magnitude lower than what was used to be considered defining in the “classic” magnetars. Despite this low intensity, this type of magnetar produces x -ray emissions similar to conventional ones. The important difference in the intensity of the magnetic fields of one and the other have led astronomers to press that the magnetism of each other has a different origin. Simulating a star. To understand what was happening in low intensity magnetars to generate their peculaires magnetic fields, the team responsible for the new study He turned to a numerical simulation with which they modeled the magnetic-thermal evolution of these objects. They observed a “dynamo process” (called Tayler-Spruit) that was given in the proto-strolle of neutrons, a process capable of generating low intensity fields from movement such as those observed in this type of stars. Relapse. According to Explain the responsible teamthe key is in the birth of these neutron stars, in the explosions of the supernovas in which they originate. As the model shows, the great of the star expelled in the outbreak ends up falling back to the new neutron star, which makes this faster unleashing this dynamo of Tayler-Spruit The details of the work were published In an article In the magazine Nature Astronomy. Five of 30. Magnetars are objects on which we still have much to learn. To illustrate this a fact can be useful: to date we have only discovered about thirty of these objects in the immensity of the observable universe. Of these only five are what we call low intensity magnetars.

Saudi Arabia has sealed a key pact to dominate the AI

Saudi Arabia is launched into the conquest of the Artificial Intelligence (AI)entering fully into the battle to lead one of the most promising businesses of the moment. The country, whose economy continues to depend largely on oil, has been looking to diversify its sources of income for years. A key piece of this ambitious plan is neom, A futuristic city that, for now, resembles more an industrial estatebut that aspires to become a luxury tourist destination and an innovation center. Oxagon, the city’s industrial center, will be the headquarters of a huge 1.5 Gigaw Data Center. Until now, most of the language models we use have been trained in infrastructure that operated on the megawatt scale, but the industry is stepping on the accelerator towards the gigawatts. There are the projects announced by goal and Oracle To prove it. This runaway growth is also exerting pressure on the energy sector of many countries. A “sustainable” project raised in several stages According to a statement released this weekthe Saudi Datavolt company will be in charge of leading the works. It is not yet clear if they will begin this year, but it has been confirmed that the data center will be built in phases. The initial investment, of 5,000 million dollarswill allow operations to start in 2028. From then on, the capital flow is expected to continue and that the works continue to advance until reaching the expected power, all under a “sustainable” approach. The announcement indicates that the data center will have “an integrated high density computer ecosystem and an energy efficient infrastructure.” One of the promises of the NEOM is sustainability. The government has promised that it aims to produce “100% clean” energy from sources such as solar energy, wind energy and the largest hydrogen plant in the world. It is no secret that they will need a lot of energy to boost this and other AI data centers in the place. The International Energy Agency (AIE) He has indicated thatin 2022, the global electricity consumption of the data centers was between 1 % and 1.3 %, and everything indicates that it will continue to increase significantly in the next decade. This scenario is promoting a Resurgence of nuclear energya source capable of satisfying the needs of large data centers and doing it stable. Now, it remains to be seen if Saudi Arabia, that still does not have nuclear plantsHe will advance in his plans. As Datavolt has pointed out, the project aims to turn Saudi Arabia into a regional reference in digital innovation and artificial intelligence. However, it is not the only country in the Middle East that aspires to lead this technological career. United Arab Emirates is also betting strongly in that regard, and proof of this is its recent multimillionaire investment To lift in France a 1 Gigavatio AI data center, part of the largest AI campus in Europe.

Almost everyone washes their teeth, but only one in 10 does well. And that is enough to do it twice a day

“Almost everyone brushes their teeth,” a group of researchers concluded from the University of Gottemburg in 2012. The problem is that “only one in ten does well.” The results were limited to Sweden, but from what we know They are still perfectly valid In the western world: we dedicate a disproportionate amount of time and resources to clean our teeth badly. Not only is citizens’ fault. And is that, As the BBC explainedstudies have found at least “66 different types of expert advice, sometimes contradictory to each other.” So we have asked ourselves … What does the evidence available about washing your teeth? How to wash your teeth? The most effective way to wash our teeth is one that understands what we wash them for. Usually, we usually believe we brush to eliminate food from the mouth; But there is something else. The teeth develop a dense biopay (the dental plate) that surrounds it and that is not easy to remove only with a rinse. We brush our teeth to remove that sticky layer manually and as much as possible. To remove it from the teeth and gums, of course. There is several techniques for thisbut now we are going to focus on the most important: that “the movement should not be made horizontally, but the brush must move from the gums to the lower part of the tooth,” explained the dentist Juan Casado Adam. And travel all the teeth, one by one, without much pre -mud or hurry. How many times do you have to wash your teeth? At least twice, Experts tell us: One before going to sleep and another as soon as we wake up. It may seem strange, but it has its explanation: saliva has a key role in inhibition of the bacterial plaque. But while we sleep we produce less saliva. Like, while we sleep, our mouth becomes more hospitable To bacteria, prior washing helps eliminate ‘waste’ that bacteria can use to develop their activity and weaken the enamel. Therefore, the washing after waking ourselves has as a key function to renew the medium loaded with bacteria that we have in the mouth and help saliva to fulfill its function. Do not you wash your teeth after meals? Actually, using medium hardness brushes, we can brush our teeth as many times as we want. And yes, it is usually a good idea to do it after eating because we remove waste that bacteria could use. However, there are exceptions: if we have consumed a lot of acidic drinks (“such as soft drinks, coffee or alcohol”), sweet or we have vomited, brushing can immediately be an error. According to Luis Cabezas Vallejo, pediatric nursewhen the pH of the mouth is acidic, the enamel weakens and brushed at that time, it can cause damage (even if they are unappreciable). As Juan Carlos Llodra explained in ABCDeputy Secretary of the Executive Committee of the General Council of Dentistas Colleges of Spain, in that situation it is better to wait, let the saliva neutralize the acids (or sugars) and then brush.

Opinions, first contact and photos

The transition to the electric car The Volkswagen group has been choking. His ID.3 It did not become the Volkswagen Electric Golf they expected. Their ID.4 and ID.5 They have had better results but they have not been the supervants that were guessed. In its high range, the Porsche Taycan It started in an extraordinary form but The results have been deflando. At the same time, in Audi, the Audi e-tron (then Q8 e-tron) has closed his Plant in Brussels and the shared platform between the Audi Q6 e-tron and the Porsche Macan It has been launched with important delay. But a company has advanced and has been fulfilling without making a lot of noise. That is Skoda, which has had in the Enyaq A really successful electric. Since it was launched, They have delivered more than 200,000 electric cars of the first electric SUV of Skoda. Now, the Czech firm redoubles its bet with the Skoda Elroq, an electric SUV, four and a half meters that will compete in which the most complicated segment of this technology is becoming. Skoda Elorq technical card Skoda Elroq Body type Five -seater SUV Measures and weight 4.49 meters long, 1.89 meters wide and 1.65 meters high. Wheelbase of 2.77 meters. Weight of 1,949 kg. Trunk 470 liters. Maximum power 220 kW (295 hp) WLTP consumption To be confirmed. Expected Autonomies: Skoda Elorq 50: 376 km Skoda Elorq 65: 428 kilometers Skoda Elorq 85 and 85x: 578 and 562 kilometers DGT environmental badge Zero emissions. Driving aids (ADAS) Mandatory by the European Union. Others 5 -inch screen for the instrument box and 13 inches for the central. HEAD-UP Display with the possibility of including augmented reality. Compatible with Android Auto and Apple Carplay by wireless connection. Wireless load of 15 W. Electric hybrid. No. Plug -in hybrid. No. Electric Yes. Useful 52 kWh battery versions (168 hp), 59 KWh Useful (201 CV) and 77 KWH Useful (281 or 295 hp). Price and launch Already available 52 kWh battery: from 34,490 euros (without discounts from the Moves Plan or commercial offers). 60 kWh battery: from 38,390 euros (without discounts from the Moves Plan or commercial offers). 85 kWh battery: from 43,480 euros (without discounts from the Moves Plan or commercial offers). 85x kWh battery: to confirm Born to push sales With the success of Skoda Enyaq behind them and with the promise that the Skoda epyq It will be the great affordable electric car, the Czech firm wants to make this Elroq an electric SUV that adds in a segment that begins to be defined as a great alternative for those who decide to jump into the electric car with a car for everything. In Skoda they define the Elroq as The electric karoq. And that has its advantages. Beyond the immediacy of electric motors or the absence of noise and vibrations, the interior space is really wide. It is a 4.49 -meter long car with 2,765 meters of wheelbase, which guarantees a very wide space for the rear seats. A 470 -liter trunk is added, which guarantees sufficient space for any average family. On the outside, aesthetically, he plays with aggressive and sharp surfaces, evolving the line we already saw in his first electrical model. It surprises its aerodynamic coefficient, which remains at 0.26 cx, which is very good record. A figure achieved by the slightly curved surfaces of its front in which the brand’s identity signs are maintained, such as a particularly muscular hood. Already inside, everything dominates the central screen of 13 inches. It is located in a dashboard that plays with the ways to “take it out” forward. In front of the steering wheel and compared to the central screen, the five -inch instrument box seems tiny. Of course, it has the precise information and you will not miss anything but it is remarkable that its quality is not, from far, that of the central panel that has good resolution and well -chosen colors. The instrument picture is combined with a head-up display that can take advantage of the functions of augmented reality. The panel is bright and reads well in all situations. The indications with augmented reality are good and facilitate the worst navigation I am skeptical with its use on a day -to -day basis, I am not sure that it is not the typical colorful function of which the driver ends up getting tired quickly. The instrument picture looks tiny next to the large central screen but framing it gives it a quality perception that does not have other Volkswagen models. What the Volkswagen group should review is its software. We navigate and sail through its infotainment system and were unable to find something as simple as moving the projection height of the head-up display. A pity in a good quality panel that can give a lot of play. In addition, it forces us to go through the screen to turn off the alarms due to speeding, which is always a bit cumbersome. The steering wheel is simple but their buttons are easy to drive and have the essential minimum. Under the screen there are buttons for rapid air conditioning functions, although the temperature or seat heating remains on the screen, a wireless load of 15 w (refrigerated, good detail) and two USB-C shots. The screen is of good quality but the menus are lioso and it is difficult to find some functions much more than it should. In general, the level of finishes feels good. They are not the most luxurious materials on the market but details as simple as frame the instrument box screen with a small visor already provides a quality perceived superior to that of other Volkswagen models where it is exposed. If we talk about its moving performance, Skoda Elroq is a vehicle that prioritizes, above all, comfort. The direction is soft but does not prevent being accurate when we linked curves on a secondary road. At a quiet and appropriate … Read more

Reaching extreme thinness is the next trend in smartphones. The question is … for what?

Samsung Galaxy S25 Edge. This is the most mysterious member of the S25 family, one that comes with extreme thinness as the main ally. After leaking some of his Key specificationseverything indicates that the final thickness of the device will be less than six millimeters. A rather spectacular design in response to a phone that has not yet left (like that is the smartphones market) but that already seems a reality: the iPhone 17 Air. The obsession with extreme thinness will be a trend in 2025. The questions are why and for whom. Samsung has advanced. He iPhone 17 Air It has been rumored for months and with quite consistent information. Except for surprise, Apple will present a new model specifically focused on the thin world. The key is that this will not happen foreseeably until September 2025, and Samsung wanted to advance. In January, together with Samsung Galaxy S25 Ultra, Samsung Galaxy S25+ and Samsung Galaxy S25, advanced the design of the Samsung Galaxy S25 Edge. A thinner phone than the rest of his brothers. But little else. The commitment. Manufacture a extremely thin telephone It has consequences, and they are never positive if we talk about hardware. The leaks tell us about less than 4,000mAh for the S25 Edge, a figure we had without seeing for years. For more miracles that are achieved with optimization, the battery capacity looks very diminished. And this is the main debate and point with thinness: if we prefer a thin mobile with less battery or thicker with plenty of battery. According to the feedback of the xatakers and the mobile requests they usually make, the battery is always a priority. Delgadeness, no. In fact, I remember that after the great reduction of thickness that brought the goodbye of the rounded design (iPhone 11), the rest of the models were growing in thickness and with it, in Mah. He iPhone 14 It was thicker than the iPhone 13and the iPhone 13 was thicker than the iPhone 12. Each and every one of these generations won MAH, and complaints with thinness were … zero. What will happen to the iPhone Air. The Galaxy S25 Edge has had to officially give up a camera, and unofficially (according to leaks) to the battery of his older brothers. The iPhone 17 Air, except for surprise with the implementation of a large-capacity carbon-silege battery, will be a phone with less autonomy than its brothers from the iPhone 17 family. Nor are we clear if it will mount the same camera sensor and Pro lenses of the PRO Models and, if so, Apple will not be easy to continue improving the size of this hardware if the body must be smaller and smaller. In other words, it is currently not possible that two phones, one being thicker than the other, have the same potential at the hardware level. There are battles to be resolved, such as The increasingly durable batteries either The increasingly bright screens But that of increasingly thin mobiles is one, perhaps, inception.

Malaga risks being a victim of his own tourist success. So your City Council already warns: it is reaching the limit

There are times when one figure says more than a thousand words, and in the case of Malaga tourism it seems to be fulfilled: last summer the hotels of the city welcomed some 418,000 travelerswell above 132,700 scored during the same months of 2005. And that is only what the INE records in its Hotel survey. What does that boom suppose for the municipality? Recently (in A report not thought to transcend the media) the City Council valued it with words of an unusual rotundity. He even suggests his concern. Black on white. Thus, frankly and without hairs on the tongue, it is how the City of Malaga has pronounced on the city’s tourist boom in A report Posted a few weeks ago. It is not frequent that this kind of documents, technical, usually arid and that they are part of the ‘internal cuisine’ of the local bureaucracy, become news. If he has done it, it is because of his tone. Malaga, “saturated”. That tourism has reached such a level of massification in Malaga that it begins to generate tensions is no novelty. In summer thousands of neighbors They went out To protest the saturation of the city, a problem that has aroused interest of the foreign press and Boarding the debate political. What is not as usual is that the Consistory exposes a scenario as stark as the Technical Report which he elaborated at the end of 2024. In it the local administration admits That Malaga “is experiencing unprecedented tourist saturation levels”, especially in the historic center, and warns: “This phenomenon causes certain areas to exceed its load capacity, negatively affecting both residents and visitors.” As if that were not enough, the document recalls that the massification of certain specific areas “congestion”, reduces the quality of life of residents and visitors themselves and affects the local economy. The other tourism invoice. “Tourism pressure can cause the expulsion of native business and added value, being replaced by souvenir stores and other shops oriented exclusively to tourists,” Add the text. “The increase in tourists promotes the appearance of illegal or low quality accommodations, affecting both the safety of visitors and the image of the city.” The document is included in The documentation of a public tender with which the City Council seeks precisely to “de -stationalize” the tourism of Malaga. And since it was signed, at the end of November 2024, it has caught the attention of both Andalusian media as of rest of Spain. Such has been its scope that the mayor of the city, Francisco de la Torre (PP), has had to clarify its content. Saturated, but only sometimes. A few days ago the councilor wanted to remove iron from the document from his own City Council clarifying that, In his opiniontourist saturation is just a specific problem, of “certain moments and days.” “Perhaps we must specify at certain times because it is not a permanent issue,” he says about the tower before remembering that the town hall already works to create “new centralities” in Malaga. In fact one of the targets of the tender that has unleashed the controversy seeks precisely that: activate alternative routes tourist that help Distribute the load of visitors, venting the center. Why is it important? For several reasons. The first is that there is an alarming idea that flies The report: The possibility that Malaga dies of tourist success. And Spain has already proven that this is not so difficult. Recently one of the most popular travel guides among the Angloplants He advised Its users visit Mallorca, Barcelona and the Canary Islands in 2025 precisely because of their massification. In the Malaga document, it is warned that saturation harms the locals, but also visitors, and can degrade “the experience” they have in the city. New yes, new no. Another reason is that the municipal report does nothing but confirm a problem, that of the Touristthat in Malaga has already generated several neighborhood protests, more expensive housing and obliged to the mayor a move token While the opposition claims a Hard response. In fact, the report that the Consistory has just published is not the first to warn of the risks of massification. In 2005 the OMAU Observatory already prevented “tensions” that could derive from “numerous tourist visits.” Since then the flow of travelers He has shot.

There are 60 countries that have signed an agreement for an “open”, “inclusive” and “safe.” And two that not: USA and United Kingdom

The event Artificial Intelligence Action Summitthe European Summit on the AI ​​that is being held these days in Paris, is leaving many headlines. We have already told how Europe has announced an investment of 150,000 million euros In AI for the next five years, but now we find another important event. And worrying. For an ethical and open. During this congress, participating countries have been urged to sign an international agreement on artificial intelligence. As indicated In the BBCthe statement advocates an “open”, “inclusive” and “ethical” approach to the development of artificial technology. The US and the United Kingdom want to go on their own in AI. Although 61 countries have signed this statement – among them France, India, Japan, Canada and even China – neither US nor the United Kingdom wanted to sign it. Their reasons have been different, but they point to the same thing: they prefer to go on their own. What has the United Kingdom said. The United Reius government has revealed that “it has not been able to agree with all the parties of the declaration”, and that “it would only sign initiatives that agree with the national interests of the United Kingdom.” Even so, spokesmen of the United Kingdom have indicated that France “remains one of our closest partners in all areas of AI.” And what has said USA. Meanwhile, US vice president JD Vance (in the image), indicated that regulating AI “could kill a transformative industry just when he is taking off.” For him this segment is one that the Trump administration “will not miss”, and said that “the growth of the growth of AI” should be prioritized “above security. Europe is “strangling” the AI. The American president was hard with the European Union, indicating that regulation should strengthen and boost the development of AI, “instead of strangling it.” His advice is that Europe contemplates “this new border with optimism, instead of restlessness.” Macron advocates regulation. Meanwhile, the French president, Emmanuel Macron, defended the need to expand regulation. “We need these rules for AI advance to,” he explained. “It is not a matter of resistance, it is not a matter of preventing innovation, it is a matter of allowing (innovation) to occur internationally while avoiding fragmentation.” But fragmentation seems inevitable. The agreement seemed a good statement of principles to try to seek consensus when avoiding major evils caused by AI, but the differences in regulation are evident since it began to talk about the subject. The United States has always had an approach that prioritized safety growth and development, something similar to what China has done (but with Open Source models). Meanwhile, in Europe the regulation has been central issue although despite this there have been important advances by private companies such as Mistral in France or Freepik in Spain.

Venice invented an entry rate to stop mass tourism. It has come out so well that it will double the price

Tourism is equal to massification in Venice. It is nothing new and, in fact, the enclave has been a pioneer in some regulations that have sought to put the hordes to combine the life of the premises and that their ecosystem does not end up engulfed victim of their own success. His geography simply does not give for more, and that’s why they have imposed Bumpers to large groups with fines Whoever passes, or even They have tracked phones. They also imposed A pioneering tollan entry rate that went so well that They doubled the days. Now also the price. The experiment is consolidated. As we said, Venice is a pioneer in the imposition of An entry rate for single -day visitorsand success has been such for the administration that They have decided to duplicate the rate in 2025, raising it from 5 to 10 euros for those who enter without accommodation reserve. In addition, and as we explained a few months ago, The measure will be applied in 54 days a year, almost twice the 29 days selected in 2024. The dates include a continuous block from April 18 to May 4, followed by every Friday, Saturdays and Sundays until the end of July. The collection will remain from 8:30 am to 4:00 pm, and those who reserve at least four days in advance may pay only 5 euros. What do politicians say. The Tourism Councilor, Simone Venturini, gave a track of the announced change. Apparently, at the Milan Bit fair, he said that the 2024 pilot project was so successful, achieving its goal of managing tourist flows and discouraging massive tourism of a single day, which they have decided to enhance it. In fact, International destinations such as Formentera in Spain either Kyoto in Japan They have shown interest in replicating the Venetian initiative. Impact on the tourist rate. In 2024, almost half a million tourists (485,062) paid the entry rate, that is, that They generated 2.4 million euros in revenue to public coffers (The cost of the system or the destination of the funds collected) has not been revealed. The registration data indicates that, after the Italians, the main tourists were Americans, Germans and French. In addition, the measure achieved a slight reduction in the number of visitors from the Véneto region, although the authorities have not given figures. We also remember that despite this tariff increase, access remains free for those who spend the night in the city, although They must register online in CDA.ve.it to obtain their exemption. Travelers who only transit Piazzale Rome, Tronchetto or Stazione Marittima, as well as those who visit the outer islands of the lagoon (Lido, Murano and Burano) without going through the center are also exempt. The future in Venice. It is the big question. The authorities admit that the rate alone is not enough to manage mass tourism, but they do consider that The created system feels the bases for future regulations stricter. Venice, that Receive tourists from 194 countriesremains one of the destinations most affected by tourist overexploitation, which has led to the implementation of increasingly restrictive measures in an effort to protect its fragile urban ecosystem and preserve its historical character. One more than difficult equation.

South Korea has found a great structure in the waters that is disputed with China. It is the second time, and Beijing does not deny it

The conflict It began in the months of April and May 2024. In front of its coasts, in The yellow seaSouth Korea sighted a series of floating structures in the space that delimits the nation with China. From Beijing it was tried to reassure the neighbor explaining that what they saw only had fishing connotations, but no one escaped then that behind the movement could exist much more. New structures have turned on the spirits in Korea. A new dispute zone. As we said, a few weeks ago China began The construction of maritime infrastructure in the yellow seaa strategically crucial area between the Chinese Costa and the Korean Peninsula. The new facilities, A floating steel structure of more than 50 meters high and widewere detected by South Korean satellites, raising concerns that China is using the tactics of consolidating territorial claims through permanent constructions. With An area of ​​417,000 square kilometers, the yellow sea is rich in marine resources, oil and gaswhich makes it a key point of economic and geopolitical interest for both nations. Until now, South Korea has protested by the installation of Several structures since 2024claiming that these could be part of a major plan in China to exercise sovereignty over the area. In fact, the South Korean authorities believe that Beijing could build up to 12 of these structures, which would turn the area into a friction point into the already tense relations between both countries. China and its maritime tactics. The strategy of building permanent structures to affirm sovereignty is not new in Chinese politics. Moreover, Beijing has applied similar tactics in the South China Seawhere has transformed reefs into military bases And he has claimed jurisdiction on disputed waters with the Philippines, Vietnam, Malaysia and other countries. Everything indicates that the strategy seems to spread to the yellow sea, with direct implications for South Korea and its allies (Particularly, the United States). What does China say. We said it at the beginning. Chinese officials They have tried to minimize controversyalways describing these facilities as “fishing support infrastructures”but the South Korean security community fears that they are advanced for an eventual statement of Chinese sovereignty. In the words of Sang Hun Seokformer South Korean Diplomatic and Security Analyst, “these facilities act as the maritime equivalent of boots on the ground, establishing a physical presence that China will then use to consolidate their claims.” The provisional measures zone. The truth is that the yellow sea has been a historical dispute area between China and South Korea. In 2001, Both countries established the one known as the provisional measures zone (PMZ) to administer the area of ​​exclusive economic zones (ZEE) and avoid confrontations, delimiting fishing rights and prohibiting new constructions or the exploitation of resources until reaching a permanent agreement. Under it, the two nations are prohibited from building infrastructure or exploiting resources beyond fishing if the other does not agree. What happens? What South Korea He has repeatedly denounced for years that China has ignored these restrictionsallowing their fishermen to operate illegally in the South Korean Zee. Said dispute has even led to violent clasheswith South Korean maritime patrols shooting against Chinese vessels on more than one occasion. Hence, the construction of permanent structures is now seen as a new level of provocation, as it could sit a precedent that Weakens the capacity of South Korea to assert your maritime rights. The elephant in the room: USA. He Mutual Defense Pact between South Korea and the United States makes this dispute just a bilateral issue. With 28,000 American soldiers parked in South Koreaany Chinese movement that alters the strategic balance in the region could attract Washington’s attention. Until now, Americans have maintained a containment approach against Chinese expansion in the Indo-Pacific, particularly in the South China Sea and the Taiwan Strait, but but The yellow sea could become a new piece on the game board. Dispute with historical roots. From the Chinese perspective, Yellow Sea control has a strategic and symbolic weight. The reason? In the last 200 years, The great battles that defined the history of China were fought in this regionfrom the Opium wars until The Sino-Japanese war. Under this perspective, Beijing’s official narrative considers these wars as a historical humiliation imposed by foreign powers, and recovering absolute control over its coast is seen as part of the restoration of his “historical law”. The Chinese argument to reject an equitable division of the ZEE with South Korea is based on the fact that Its population and their coast are significantly largerso they believe that the dividing line should favor them. On the other sidewalk, South Korea and its allies defend the principle of the “midpoint”, according to which the maritime border should be drawn equally between both countries. And where do it leads to us? It is the big question. Of course, so far the dispute has not reached the seriousness of the Conflict in the South China Sea or the Eastern China Sea, where the Asian nation maintains confrontations with the Philippines and Japan respectivelybut the situation could quickly intensify if Beijing continues to expand its presence. It would not really be “so much.” If South Korea, with the support of the United States, decides to directly challenge these constructions, we could see a new front of tensions in the Indo-Pacific. Perhaps for this reason, at this time the great unknown is to know how far South Korea will allow (and its alliance with the United States) that Chinese tactics advance before taking more forceful measures.

Grok 3 does not arrive and Xai is staying behind

In the last hours we have known The offer Elon Musk has made Not by OpenAi as such, but for the one by the non -profit association (nonprofit) that controls it. That has unleashed a debate about the true reasons for this offer, but also leaves a question in the candlestick: in what situation is Elon Musk in the AI ​​segment? Hi, Xai. Elon Musk carries in a Open war with Sam Altman for years, and in fact In April 2023, Xai created to develop their own AI models. Since then the company has launched some AI models and made striking advances with Grokbut it seems to be left in many lands. In others, yes, it surprises. Grok was sarcastic … In November 2023 XAI Grok presentedthe AI ​​model that competed with Chatgpt and did it with a striking characteristic: had a sarcastic tone. From its launch and for months Grok It was only available for X subscribers. … and Grok 2 has no censorship. In August 2024 the new version was presented, Grok 2more advanced and powerful. However, what caught the attention of this model was its apparent lack of censorship. Thus, it is possible Generate images of any kind, including Deepfakes of famous peoplesomething that other models do not allow. Elon Musk and XAI announced in December 2024 that They opened the model To all X users without having a payment subscription, something that undoubtedly promoted its use and popularity. Grok 1 is “Open Source” (but Grok 2 No). One of Grok’s striking features is that Elon Musk shared this project as Open Source. The gigantic original model, of 314,000 million parameters (314b) was then four times larger that calls 2, the other great reference in Open Source models, with 65b size. The funny thing is that Grok 2 is not: it is not in the Official XAI repository In Github, and there is no news that the same thing that happened with his predecessor will happen. Investment rounds. In November 2024 Elon Musk got lift 5,000 million dollars For XAI, who joined the round of 6,000 million dollars that raised in May 2024 and at least two other planned rounds According to Crunchbase. The firm certainly seems to have notable funds, but be careful, because it is surely burning them, as with OpenAi. 100,000 NVIDIA GPUS. Last summer Musk lit “The most powerful the world of the world“, which apparently was baptized With the name of Colossus and that has 100,000 GPUS NVIDIA H100. It is supposed to be used to train its new model of AI, Grok 3, and of course having that computing power is theoretically a guarantee to stay competitive with its rivals. Where is Grok 3? But the truth is that Grok 3 still does not appear, and that Musk promised to have it ready in December. Musk Indian In January that Grok 3 “will arrive soon” and that the pre-training stage was complete and had used 10 times more computation capacity than with Grok 2. In Tom’s Hardware they also point out that XAI has used the data generated by users of X for that training. Reasoning models and AI agents. The great unknown is what will happen with XAI in two areas where its competitors are advancing to forced marches. Deepseek R1 has promoted the Free availability of reasoning models, but there are also several AI companies that have already shown agricultural models such as Operator of OpenAi or Computer Use of Anthropic. That XAI knows does not have alternatives at the moment. The rear. All this makes it clear that today Xai continues to rely in most proposals in the market. His models are not the best, he has no reasoning models or public agents, and Musk seems to be more interested in putting the Zancadilla to Altman already OpenAi than to get XAI to lead this technological career. Even so, surely there will be news of the company soon, and it will be then that we can value the real situation of it. Image | DVIDS | XAI In Xataka | Chatgpt and its rivals are sosainas.
