The US has detected an object in space with strange behavior. The source that released it has also located: Russia

by

Last year there was a fact that formalized the rhetoric of the “spatial war” It was a fact. It was known, in some cases it was intuited, that the United States, Russia and China had transferred their confrontations hundreds of kilometers from the earth through their satellites. However, in December any glimpse of doubt was cleared: United States He designed the bases of a war attack in space. Now they have detected something unusual, and their source comes from Moscow. First was surveillance. In March, The CNN counted that the Pentagon had intensified the surveillance of the spatial activities of Russia and China in the face of growing evidence that both powers are testing New capabilities Offensive in orbit. As American defense officials then said, Russia had carried out coordinated satellite exercises that simulate attack and defense tactics, including maneuvers in which several satellites surround and isolate another, demonstrating a possible scenario of neutralization of enemy ships. China, meanwhile, had executed similar maneuversincluding the closed formation of satellites and offensive approach practices, actions that reinforce suspicions about the growing militarization of outer space. Three satellites and a stranger. Thus we arrive at the news of these days. Russia has launched space three highly secret satellites (Kosmos 2581, 2582 and 2583) that have revived concerns about a possible preparation for space war. On February 2, the satellites were sent to orbit aboard a Soyuz rocket, without Moscow revealing details about their purpose. Not just that. To the unusual maneuvers they have performed since their deployment, the recent appearance of A mysterious objectpossibly released by the Kosmos 2583 satellite on March 18, whose strange draw Observe with concern. The United States’s space force has already cataloged the new object, while some speculation suggests that these satellites could be practicing “attack and defense” tactics orbital, designed to isolate or neutralize enemy satellites in case of a future conflict. Trajectory of the object detected Theories Although astrophysicist Jonathan McDowell, from Harvard-Smithsonian Center, nuanced interpretations Alarmists when considering that the observed maneuvers can simply be due to similar orbits, recent history also reinforces skepticism. In 2022, Russia had already launched the Kosmos 2558 in the same orbital trajectory as an American military satellite, which was interpreted as an act of spatial espionage. The geopolitical context and the background of the Kremlin in the matter of covert technologies They raise suspicions that this new satellite trio may be carrying out surveillance missions, interception or testing tests Antisatellite technologiesalthough for now there are no conclusive evidence of hostile actions. The “conquest” of space. We said it at the beginning. The maneuvers attributed to satellites Kosmos 2581-2583 They are framed in a broader scenario in which both Russia and China would be exploring New combat capabilities orbital. The Recent CNN reports They quote officials of the United States Department of Defense, who say that both countries are carrying out military training in low orbits, a key zone for their proximity to land and its frequent use for communication, recognition and intelligence satellites. This trend reinforces the fear that space will be consolidated as a new confrontation field Strategic, one where powers develop technologies to deactivate, interfere or even destroy enemy space assets. Uncertainty and surveillance. So far we write, the nature or function of the object released in March has not been determined with certainty, which increases the tension around this satellite trio. McDowell explained That between February 25 and March 14, proximity operations were registered between the satellites, and that two of them passed near Kosmos 2583 on March 7, although it could not be confirmed if there was an attempt at offensive coordination. Even so, the US spatial force maintains close surveillance on the orbital movements and patterns of these artifacts, given the possibility that it is covert tests of new military capacities in space, a dimension that is no longer purely scientific or commercial, but also tactic. The challenge of “interpreting.” In the background, a problem that until now had not taken place in space, that of the opacity of the nations with respect to the missions of their satellites and the repeated use of covert technologies in their space operations that make it difficult to obtain certainty. In an environment where the simple fact of sharing orbits or making approaches between satellites can have both harmless and aggressive aims, analysts, in this case of the United States, must move between caution and prevention. As We already explainedwhile the calls multiply to establish clear international standards on behavior in space, Washington and its allies already consider spatial domain as a Active strategic theaterand each new mysterious object, such as the newly released by Kosmos 2583, adds one more tension layer to technological and military rivalry in orbit.

Madrid wanted to make Bernabéu a new concerts. Aitana has given the tip to her plans

by

Aitana announces that abandons its long caregified purpose of acting in the Santiago Bernabeu. His two performances, with tickets exhausted in just 72 hours, were scheduled on June 27 and 28 of this year, and carried delay since the initial December 28 and 29. In the end, the artist has decided to take her show to the Atlético de Madrid stadium, the Wanda Metropolitano. It is not the first, and it is the temporary lock and without a clear solution of solution for its purpose of becoming a concert center on European scale. Aitana says enough. Aitana’s concerts will end up being held, but on July 30 and 31 and at Wanda Metropolitano. He was the only artist who was left out of Santiago Bernabeu’s programming: before her, others such as Lola Indigo, Dellafuente or the veiled 5 of Ibai have relocated (in the case of the latter, for example, well far from Madrid: in the Cartuja of Seville). The reason has not become official, but with total security it is the same problem that forced to delay the dates of December: the lack of compliance with the enclosure with the municipal regulations on noise. An announced debacle. Aitana’s announcement coincides with the date on which, in theory, problems with sound were going to be solved: March this year. However, experts already anticipated that the purpose was complicated: Francesc Daumal I Domènech, acoustics expert Consulted by eldiario.eshe affirmed that “in six months the problem will not have been stopped, in fact it is most likely that they will continue to think how to solve it.” In the chiringuito, Josep Pedrerol ventured what would cost such a reform: Between 20 and 25 million euros. Expenses and more expenses. The pharaonic Real Madrid project has meant reforms by value of 1.1 billion eurosafter chaining up to three loans. But the promises of turning the stadium into a nerve center for concerts throughout Europe did not satisfy the neighbors, the first to They caught attention of media and Internet users on the noise in the area. And not only that: a thousand neighbors grouped under the Association of affected by the Bernabeu They are concerned about the agglomerations that the concerts generate, the dirt and the volume of noise in the streets that are out of the stadium control. Another tourism. That is, characteristics easily associated with the transformation of cities into immense Attractive parks for tourists. Santiago Bernabeu reforms have gone from being a Megalómano project of the football club to a point of interest for the City Council, which has facilitated the works of works for parking attached to the field, with Very advantageous concessions for the club. José Luis Almeida, mayor of the capital, is very interested in the works reaching good, especially considering The figures. Thanks to the stadium, which in 2024 He received artists like Taylor Swiftthe music industry billed 185 million euros in the city, compared to 94 raised in 2023. Taylor Peta. Taylor Swift, according to APM figures, added 126,393 spectators in two days, which undoubtedly affects the City Council very positively. The Consistory itself figure at 79 million euros the amount of money that moved this event, if we have prices of tickets, hotels, travel and hospitality. Bernabeu also has an advantage with respect to others: he does not need neither good time nor, thanks to his retractable grass, wait at the end of the football season. You can program, unlike the Olimpic Stadi or the Metropolitan Wanda, concerts all year. The largest enclosure in Spain. The Santiago Bernabeu plans to become the largest enclosure in Spain, which exceeds the Olimpic Stadi of Barcelona, ​​where 57,500 spectators fit. This is followed closely by the Wanda Metropolitano de Madrid (57,300) and the Cartuja of Seville (42,800). From there the figures already fall to, for example, the Miguel Ríos de Rivas Auditorium, with 29,700 of Acti. Currently, artists of great international presence sometimes jump the capital to go to Barcelona, ​​where they find more capacity with the Estadi Olimpic, as has happened with Lady Gaga, Billie Eilish or Guns N ‘Roses. An indefinite problem. However, it does not seem that at the moment the problem will be solved. In Europe there are still enclosures where European artists stop, such as the Défense Arena in Paris (40,000 spectators) or the London O2 (20,000) between the cutlery, and Croke Park in Dublin and the Stadio San Siro in Milan, both with more than 80,000 people of capacity, among those discovered. It is clear that Madrid would not be bad for an enclosure with the spectacular characteristics of the Bernabeu (extraordinary and covered capacity), but everything indicates that, with the sounding problems, it will take it even to arrive.

The international wine market was already broken, but a single idea has put it against the ropes: 200% tariffs

by

13%. That is the magical figure because, given the uncertainty of what will happen to the tariffs, that is what the “main consumer country in the world“For Spanish wine. In 2024, to get an idea, they were sent 97 million liters valued at almost 400 million of euros. That’s why The announcement of a 200% tariff and the letter of the United States wine alliance (USWTA) recommending “Sorted to US companies that They suspend all the shipments of wine, liquors and beer from the EU “has fallen like a jug of cold water in a sector that was already very scrambled. And that has not even been a big surprise. In December 2024, after Trump’s choice, Exports fired 23%. And, during these months, many Spanish wineries have been protecting preventively anticipating the sending of reserves to American soil. What has surprised has been the entity of the coup: no one expected a 200% tariff and, although was suspended, As I pointed out Jose Luis Lapuente, general director of the Denomination of Origin of Rioja, “much more harmful than tariffs itself is uncertainty, not knowing.” That is precisely what is behind the USWTA letter: despite its efforts so that tariffs do not apply to goods that are already in transit, the US government has refused to give a clear answer what it will happen. If companies do not suspend shipments, they could meet huge losses overnight. “Deep concern” Last Thursday, the Brussels Regions Committee hosted an emergency meeting of the intergroup of wine to ask the commission to “take out the wine from the tariff war.” And, a priori, it seems that the pressures have had an effect because the union left out of his countermeasures to wine, sparkling and the American bourbon. In this context, it is not only to avoid more reprisals from the White House and prevent European wine sales from collapseing in the US, it is about Protect huge investments that the sector (and union) have done in the North American market during the last decade. “The tariffs announced by the US are totally unjustified in the particular case of the wine if we consider that currently the tariff difference between the rates that apply the EU and the US is minimal,” reasoned the general director of the Spanish Federation of Wine, José Luis Benítez. However, we have already seen in recent days that the Trump administration strategy is difficult to understand. In fact, it is a measure that does not convince anyone … “This will be great for wine and champagne businesses in the United States,” Trump wrote when he threatened with the 200%tariff. However, not all American producers They agree. Because, although it is true that the price increases can ‘rekindle’ the interest in the broths of the country, we talk about a fragile sector, overloaded and very touched by the fires and droughts of the main producing area, California. Not only that. As John Williams explained at CNNfounder of Frog’s Leap, a winery in the Californian Valley of Napa, US wineries are just a very small part of the commercial chain. If tariffs harm distributors, the problem will be rapidly generalized. In the end, “we all depend on the same distributors. The health of these companies is important for wineries around the world,” said. … and that can become counterproductive. Because, the American tariff system has peculiarities that can end up running the market completely. The clearest example is that “the US customs and border service. offers reimbursements of certain rights, taxes and fees paid for imported items, provided that the company exports similar articles. ” That is, the big distribution platforms can end up flooding the most expensive European products market as a strategy to compensate for the price of tariffs. Although, in reality, the background problem is another. That world wine is going through a very bad time. In September 2023, Luigi Moio, president of the International Wine Organization, climbed into a gallery in the heart of La Rioja and said “Vineyard’s start was something inevitable.” And it’s not just La Rioja, of course. In France (which can serve us as proxy of what happens in the international sector), already It has been assumed That 100,000 hectares of vineyards will have to be started – in fact, they have launched a plan to start about 30,000. It is the only way that the sector finds for a devilish situation: that the sector does not stop growing, but These floods “They are not enough to cover production costs and farmers’ needs.” And in that context, tariffs arrive. Are we facing a? Image | Chuttersnap | Mika Baumeister Xataka | We already knew that Spanish wine was on its way to collapse. What we didn’t know was that drought was going to accelerate it so much

Elon Musk attacks the ideologist of US Tariff Policy

by

The global economy faces one of the most tense moments in its history, after the implementation of the new US tariff policies that it has given by amortized World free trade. The reciprocal tariffs have not only rekindled the fears of a world recessionbut they have also hit some of the world’s most innovative companies hard. Among the main affected: Elon Musk, whose companies will receive a hard blow for the commercial war that the US has started with China and Europe. Elon Musk doesn’t like tariffs. Elon Musk has expressed clearly its opposition to the new tariffs driven by Donald Trump. During the weekend he proposed a Commercial Agreement of “Zero Tariffs” between the United States and Europe. In addition, Musk shared in x A video by economist Milton Friedman highlighting the benefits of free trade and criticized Peter NavarroTrump’s commercial advisor and main ideologist of Trump’s tariff policies, ensuring that: “Navarro is darker than a sack of bricks.” According to published The Washington Postthe confrontation between Musk and Navarro has been climbing. Musk has publicly denounced that these policies are harmful, not only for their companies, but also for the American economy in general. These statements show the distancing between Musk and Trump’s government. Tesla is more than an assembler. The origin of the crossroads between Musk and Navarro were A few statements in which the Economic Advisor of the White House assured that Tesla was little more than a pieces. Tesla is among the companies most affected by tariff policies. According to Nikkei Asiabetween 20% and 25% of the components used in the manufacture of Tesla cars are imported, while 40% of materials related to Electric batteries They come from Chinese suppliers, although these batteries and their cars are manufactured in the US gigafactories. However, the main stumbling block is not the extra cost of its supply chain for tariffs, but the voltage generated with Chinawhere the brand enjoys A privileged position And Musk had been acting as a mediator bridge. If the Chinese government intensifies its offensive against US commercial interests, the competitiveness of Tesla in front of byd or other manufacturers. “It is important to note that Tesla has not been unscathed from this problem. The impact of tariffs on Tesla remains significant,” public Musk a few days ago. Space tariffs: its effect in Spacex. Spacex has also felt the coup of tariffs in their meats. Export restrictions from China and Tariffs to China They are being a serious obstacle in the Company’s supply chain. “Tariffs are generating challenges in various facets of Spacex operations, including the costs of the supply chain, international contracts and the regulatory environment,” He pointed outto Forbes Maxime Puteaux, main advisor of the space consultant Novaspace. This problem could have long -term consequences. On the one hand, they affect Spacex’s ability to comply with international contracts, including those of the Satellite display For Starlink. On the other hand, these increases could slow down and even put development at risk of projects such as Starship, a key piece for future missions to Mars. Musk has warned that this type of commercial policies endangers American technological leadership in strategic sectors such as aerospace. “There are certain components or elements that are used in the construction of high -tech products such as Spacex that do not have many alternative suppliers, so the risk of concentration is aggravated when costs increase exponentially,” declared to Forbes James Gellert, Executive President of the Raphydrification Supply Chain Analysis Firm The AI ​​is not fought. The AI ​​does not get rid of the scourge of tariffs, so Xai, the growing company Musk’s artificial intelligence, also faces some problems for tariffs on key components, such as electrical equipment and servers for Your data centers. This increase in expenses not only affects the competitiveness of the company, but could limit its ability to face international rivals in the field of artificial intelligence, a Sector where China and Europe are advancing quickly.

The United States has been fantasizing with an “made in USA” iPhone. Now you will have one made in … India

by

The Commercial War unleashed by Trump He is forcing Apple to look for alternatives for its iPhone, especially for those dedicated to the United States, with India arising as the salvation table against tariffs that threaten to shoot prices. The current situation. Apple has suffered its worst stock market fall in what we have of the century, collapsing 20% ​​in just three days After the announcement of the new Trump tariffs that impose 54% of Chinese products compared to only 26% to the Indians. The company, according to The Times of IndiaIt is quickly redirecting iPhone manufactured in India towards the US market, in a defensive maneuver to mitigate the immediate economic impact while looking for long -term solutions. Why is it important. This crisis could accelerate a geopolitical change in global technological manufacturing, with India gaining ground at the expense of China as the main electronic production center. The transfer is not limited to avoiding tariffs: diversifies geopolitical risks and takes advantage an Indian market that is booming. The great myth. The fantasy of an “iPhone made in USA” promoted by the Secretary of Commerce Howard Lutnick It is economically unfeasible. It is quite obvious but details it well 404 average. An iPhone that costs $ 30 assembled in China would require $ 300 in the United States. A complete restructuring of global supply chains established for decades would be needed. Even manufacturing in his country, Apple would continue to depend on imported components subject to tariffs. In figures. Current tariffs would increase the cost of production of an iPhone 16 Pro 550 to 850 dollars (300 more dollars), while from India the increase would be “only” 150 dollars. If Trump fulfills his threat to raise tariffs to 104% in total for China, the extra cost could be shot up to $ 600 per unit, according to Newsweek. The pragmatic option. India is emerging as the viable and already underway alternative, with the capacity to manufacture about 25 million iPhone per year, sufficient to cover approximately 50% of the US demand if it redirects all that production to the United States According to Bank of America. Apple does not start from zero in India. Since 2017 he has gradually transferred part of his production there, starting with old models and expanding to the most recent, as highlighted The Wall Street Journal. The political perspective. India and China maintain a historically tense relationship marked by territorial disputes and competition for regional influence, such as the Military confrontation in the Galwan Valley In 2020. Apple is in the midst of this rivalry, turning a business decision into a movement with diplomatic implications that could intensify competition between both powers. And now what. Tim Cook, presumably, will try to negotiate tariff exemptions while gradually increases productive capacity in India, but we should not expect drastic and immediate changes. This is an inherently slow process. China will continue to be a pillar for Apple. Right now he continues to assume 80% of its productive capacity in general and 90% of the iPhone in particular, compared to the 10-15% that India represents. In the medium term, we could see an even more diversified production, with Vietnam (than already manufactures 90% of the Apple Watch) and other Southeast Asian countries gaining weight in the supply chain.

The US tariffs are a weapon of mass destruction in the Tech industry. Except for Chinese mobiles

by

The 104% tariff Chinese tax By the Trump administration it will shake the foundations of the smartphone industry. Apple and Samsungthe two great actors in the sector, base a good part of their manufacturing strategy in countries especially penalized by these new measures. However, Chinese mobile phone manufacturers could better overcome the blow. Thanks to a strategy focused for years in international expansion and markets outside the United States, their direct exposure to the impact of these tariffs aims to be considerably less. 104%. USA He has officialized a 104% tariff to imports from China, carrying The commercial war between both countries to its peak maximum and leading us to a night of movement in the markets. The consequences have been immediate: Fall of almost 5% in Bag for Apple generalized in the rest of great technology, with the uncertainty of a new commercial scenario that will shake its current strategies. Chinese and United States manufacturers. For Apple and Samsung Import products manufactured in China or Vietnam to the United States will involve an increase in simply unassumable costs without price increases. A case that barely applies Chinese manufacturers, since they have never had too much presence in the country. Giants such as Xiaomi, Oppo or Vivo do not sell smartphones in the United States. However, OnePlus, TCL and Motorola (Property of the China Lenovo) do have a presence in the territory. In fact, Lenovo is the third smartphone manufacturer in the United States. The Lenovo case. Motorola and Lenovo are in the most compromised situation after the entry into force of tariffs. The manufacture of its devices is focused on countries such as China, Brazil and India. Importing the United States with 104% tariffs is simply unfeasible for the company, which would have to move its production chain outside China to survive in the United States. Although not even maintaining a diversified production would be sufficient to partially overcome the impact of tariffs. The Type imposed on Brazil is 10% (the minimum threshold), while that of India amounts to 26%. A 10% tariff is assumed through a light rise hybrid strategy and cost absorption. One of almost 30% requires more drastic measures. The consequences for the rest. On the side of OnePlus and TCL, despite being Chinese manufacturers, they have been making production to countries like India and Brazil for years, diversifying strategy for their product assembly. A diversification that is not enough to overcome tariffs, since the bulk of manufacturing remains in China. The only solution? Move in record time the production outside your native country and centralize efforts in external factories. A withdrawal on time. The most likely scenario after the implementation of tariffs is the disappearance of the little Asian trace that remains in the United States. With the exception of Motorola/Lenovo, this has never been a market to be conquered by China, a position that aims to reaffirm after the crossed commercial war. Beyond mobile phones, companies like Xiaomi, which They sell household products and monitors In the United States, they will have it difficult to maintain presence in the country without raising prices abruptly. A global impact. If manufacturers such as Motorola renounce the US market, with the consequent loss of income that this would entail, an increase in prices globally seems inevitable to alleviate the effects of losing presence in a key territory. Companies such as OnePlus, TCL or Xiaomi, with a minimum presence there, would have it easier to absorb part of this small loss and not end up moving costs to consumers outside the US. Despite this, not everything is so simple. Although Chinese brands do not sell mobiles significantly in the US market, they do have a presence in other categories such as televisions, monitors and home devices. The unknown is whether they will choose to compensate for the blow by increasing prices only in those lines, or if they will end up moving the extra cost to their entire catalog, including smartphones. THE WAR OF COMPONENTS. The main Chinese manufacturers use American components, such as Qualcomm processors or Corning Gorilla Glass crystals. At the moment, this situation would be under doubt, since Qualcomm subcontracts the production of its chips to Taiwanese giants such as TSMC or Samsung Foundry (South Korea). Something similar happens with manufacturers such as Corning, which diversifies production with plants in Asia and Europe to meet global demand. Given that US sanctions They prevent American memoirs from selling their most sophisticated integrated circuits to their Chinese clients, China does not have it easy to reduce dependence on the United States.

While Spain was pending the rains, something strange was happening with the polar vortex

by

The meteorology of the month of March has been marked by the wave of storms that have left intense rains throughout the Iberian Peninsula. While many monitored attentive to the possibility that the channels overflow in their surroundings, in the high layers of the atmosphere there was an important phenomenon, the disruption of the polar vortex. New animation. NOAA (National Oceanic and Atmospheric Administration), The agency responsible for analyzing weather and weather in the United States, has shown us the disruption of the polar vortex occurred during last March. He has done it through a new animation in which the drastic changes can be seen The polar vortex. First of all, remember that Polar vortex It is an intense atmospheric current that transports cold air around the pole at stratosphere. In winter, the polar circle stops receiving sunlight so the air at the height of the stratosphere cools. In contrast, the warm air of sub -reliable areas continues to be tempered at these altitudes, which leads to expand north. The terrestrial rotation makes this pressure a powerful current of air that surrounds the pole in winter. Although the current is always active, it suffers important changes throughout the year. The first change is in intensity: it is during the winter months that the winds of this current reach greater force, reaching its middle peak towards the beginning of January. The second change is in the direction. Due to the inclination of the earth’s axis, approximately between spring and autumn, the current moves away from the pole to the torque that loses intensity because the sun enlightens the pole again, heating his stratosphere and reducing the contrast with lower latitudes. This implies that high latitudes the current stops moving from west to this but does it from this to west. When the vortex breaks. However, the current can suffer a sudden change, a disruption. These cases are usually due to sudden stratospheric warming in the pole. This “pushes” the current out. This is what happenedexplains the NOAA, last March 9: rapid stratospheric warming generated a disruption of the current that has led her to circulate in reverse and intense in high latitudes. Return to normal. If a disruption occurs during winter, it is common for the vortex to return to its usual circulation after one of these disruptions. If this disruption occurs during spring, it is likely that the circulation will pass to its summer shape, outside the pole. It can be expected, due to the dates, that the evolution of the vortex now takes it back to the average. Last year We saw a vortex disruption that reversed the dominant direction of the wind in early March, however the vortex recovered its direction and intensity of these dates before reversing its spring channel. Graph in which the speed and direction of the stratospheric wind is illustrated in the 60ºN latitude. The fine blue line marks the average evolution in the 1991-2020 period; while the thickness marks the evolution between 2024 and 2025. The shadow represents the variability observed and the pink forecasts. Laura Ciasto/NOA “Like an atmospheric diva. ” This year the models indicate that this will not be the case, which implies that we are facing the change in earlier in the records since 1958. This concludes the “season” of activity of the polar vortex, a season marked by a high intensity circulation and important volatility. A closure that has lived up to the season, according to NOAA. “For a good part of this winter season, the polar vortex has been strong, stretched, and not very interested in interacting with the troposphere. But like a real atmospheric diva, the polar vortex had a last ace in the sleeve, disintegrate in a spectacular way and bring with him some cold air,” NOAA itself explains in a piece in his blog dedicated to the polar vortex. And then what? In the result of all this is that the circulation of the vortex is now maintained in northern Europe and that can reach affect weather of the continent. How this arrival will depend on factors such as the interaction between this mass of air and the troposphere or what low latitudes could reach circulation in that month of April.

Chinese memory chips manufacturers are a nightmare for the US and South Korea. There is a lot at play

by

Yangtze Memory Technologies Co. (YMTC) is one of the largest memory chips manufacturers in China. Its quota in the global market is approximately 6%so it is far from South Korean companies Samsung and SK Hynix, and also from the American Micron Technology, the three companies that lead this sector. Even so, Its weight in the Chinese market is very largeespecially because US sanctions They prevent American and South Korean memories manufacturers selling their most sophisticated integrated circuits to their Chinese clients. YMTC is in the spotlight of the US administration for more than two years. In fact, at the end of 2022 the Department of Commerce led by Gina Raimondo He decided to include this company in his blacklist because he had managed to develop an ambitious 128 layer memory chip. Currently YMTC is one of the companies that have the most advanced semiconductor manufacturing technology in China, and curiously, According to Techinsights He has reached this position without resorting to foreign technology. Not even Asml’s. YMTC aspires to intimidate the leaders of the memory chips market This achievement seems to have been possible because YMTC has the complicity of three of the most important Chinese lithography equipment: Naura Technology, Amec (Advanced Micro-Fabrication Equipment Inc. China) and Piotech Inc. The most shocking thing is that according to Techinsight analysts, which is a Canadian communication platform intimately linked to the semiconductor industry and with Great credibilityYMTC has managed to put avant -garde memory chips capable of rivaling the most advanced foreign solutions. YMTC has published about 20 new patents in which it describes processes that seek to increase efficiency And it has managed to refine its technology of stacking of memory cells in layers known as ‘xtacking’ until reaching a level of performance in its integrated nand type circuits similar to that of the comparable memories of Samsung or SK Hynix. However, this is not all. According to SCMPYMTC has recently published about 20 new patents in which it describes processes that seek to increase efficiency and optimize chips stacking structures. It is evident that the development of the technological capacity of Chinese manufacturers of integrated memory circuits represents a threat to Samsung, SK Hynix and Micron Technology. However, YMTC is not the only Chinese company with the ability to put in trouble the manufacturers of South Korean and American memory chips. Changxin Memory Technologies (CXMT) is one of the Chinese companies specialized in the production of memory chips, and, like other companies in the country led by Xi Jinping, it has chosen to compete in this market so attractive deploying a very aggressive pricing policy. CXMT in particular has increased its production capacity of DRAM chips almost five times during the last four years, which has allowed it to increase its global market share until it reaches a very worthy 9%. This growth has placed this company just behind Micron Technology if we stick to its market share, so it is already the fourth largest memory chips manufacturer on the planet. To curl the curl even more The Chinese government is supporting economically to its manufacturers of this type of semiconductors in response to the sanctions deployed by the US and its allies, so the competitiveness of Chinese companies is upwards. More information | SCMP In Xataka | China needs to develop a new type of immune chips to US sanctions. And their scientists have just achieved it

The largest military base on the planet

by

During The cold warthe Soviet Union prepared for “the worst” building a large number of Underground bases and bunkersresistant structures that could face nuclear attacks. In Germany also tell with a large number of these vestiges of war conflicts of the past. In China, since 1980 there is a group in charge in the creation of deep shelters capable of resisting the most powerful western bombs. The team has silently lifting an unpublished work: the largest military bunker on the planet. A vitamin “pentagon. I told it in exclusive the Financial Times through satellite images. China is developing a military complex of monumental proportions on the Western outskirts of Beijing, one that according to American intelligence would work as a War Command Center Designed to house the High Command of the Popular Liberation Army (EPL) in case of conflict, including a eventual nuclear war. The site, informally nicknamed by analysts as “Beijing Military City”it covers about 1,500 hectares (ten times bigger that the Pentagon) and is approximately 30 kilometers from the center of the capital. Satellite images, analyzed by US agencies, show deep excavations and intense construction activity, suggesting the creation of a network of underground facilities strongly reinforced and connected by tunnels, capable of resisting attacks, even with nuclear weapons. Xi Jinping’s plans. The beginning of the works, detected in mid -2024coincides with the EPL preparations for the centenary of its foundation in 2027, date for which President Xi Jinping has ordered that the armed forces develop sufficient capacity to take Taiwan. The Nuclear Arsenal Expansionthe improvement in the integration between EPL branches and the impulse of new weapons systems are part of this modernization strategy. In fact, experts Like Dennis Wilderformer head of analysis of China in the CIA, interpret the new bunker as a clear sign of China’s intentions, not only to consolidate a conventional first level force, but also to strengthen their abilities for a nuclear war. Colosal bunker, absolute secretism. The FT had that more than 100 cranes operate simultaneously in an area of ​​five square kilometers, and according to the Former Image Analyst Renny Babiarzthe infrastructure includes underground facilities connected by hidden passages. The site completely lacks common elements in civil real estate projects, such as exhibition rooms or official mentions on the Internet, which further evidences its military character. In fact, and although there is no visible military presence, there are multiple signs that They prohibit the use of drones or photography, access controls with guards and restrictions to pass through nearby tourist areas, which have been declared “Military Areas” by local residents. Start of excavations in 2024 Echoes of the Cold War. We said it at the beginning. The characteristics of the site remind the Soviet underground bases of the Cold War, and reflect the influence of engineers Like Qian Qihupioneer in the development of resistant structures to nuclear attacks after their training at the former Military Engineering Academy of Kuybyshev in the USSR. Counted on Asian Times That at least since the 1980s, Qian and his team have worked on the creation of deep shelters capable of resisting extremely powerful bombs, such as the American GBU-57A/B.capable of crossing up to 200 meters. Strategic ambition. For their part, US officials point out that the new complex would replace the current center EPL command in the Western hillsbuilt during the Cold War and already considered obsolete for contemporary security standards. The new installation would not only increase the protection of the high command against American penetration weapons, but also allow Integrate advanced communications and have space for future military capabilities. In other words, the dimensions of the complex and its partially buried characteristics point to a unique purpose: to be the main operations center China strategic in case of war. Power symbol. Researchers and analysts also agree that the project presents all the typical signals of a highly sensitive military installation, such as the Use of reinforced concrete and one Network of tunnels deep. In this regard, a Chinese researcher accessed that his size, leaving the Pentagon in “tiny” XI JINPING ambitions for overcoming the United States in strategic capacity. Plus: construction coincides with a transformation process Urbanistic of the surroundings of Beijing, in which homes have demolished in areas such as Qinglonghu, feeding speculation about the nature of the project in Chinese social networks. Precedents China already has military underground facilities, such as Command Center in Xishansouthwest of Beijing, located 100 meters deep, from where EPL maneuvers are directed since 2013. In 2018, researchers identified A karst cave In Xishan’s forest park, with an estimated depth of 2,000 meters and its own water source, an enclave with the potential for the location of a nuclear bunker. That cave is considered comparable in depth to the famous Krubera in Georgiawhich suggests that, in addition to the monumental work, the EPL is exploring reinforced natural locations for future strategic facilities. Background: Taiwan. Impossible to ignore the island. Sources close to the Taiwan Ministry of Defense They have suggested to FT That the EPL is building a new command center, although some experts question the suitability of the ground for underground bunkers. Thus, given the size of the site, it is speculated that it could also house a high -level administrative installation or a large -scale training base. HSU YEN-CHI, INVESTIGIC AND WARGAMING STUDIES IN TAIPÉI, researcher on Talegic and Wargaming, He underlined that the land far exceeds the dimensions of an ordinary military base, which reinforces the hypothesis that the site has a strategic purpose much greater. Official silence. What seems clear about the images is that we are facing a pharaonic work in times of war. Officially, neither the Office of the United States National Intelligence Director nor the Chinese Embassy in Washington offered more comments on the project to the Financial Times. And while Washington carefully observes the progress of the works, Beijing is limited to insisting on its commitment to a defensive policy and peaceful development. However, the scale, secrecy … Read more
