break the brutal leadership of Nvidia and TSMC

by

TSMC, The largest semiconductor manufacturer on the planetproduces the GPUs for artificial intelligence (AI) that are placing in the Nvidia, AMD market and many other manufacturers of this type of chips. In fact, 90% of integrated circuits for AI available in the world market TSMC has manufactured them. In addition, in its client portfolio Apple, Nvidia, AMD, Qualcomm, MediaTak, and even Intel, among many other companies that are dedicated to the design of integrated circuits. We are now with Nvidia. The company led by Jensen Huang currently monopolizes about 90% of the market of the GPUs for Ia. It is likely that in the medium term its quota will be reduced against the presumable growth of competitors such as Huawei or AMD, but right now Nvidia has no reason to worry. And it does not have them because the semiconductor market to grow a lot over the next few years. According to the AMR consultant (Allied Market Research) In 2031 it will have a billing volume of more than More than 263,000 million dollars. SMIC and HUAWEI are China’s spearhead in the chips and AI industries Jensen Huang, the general director of Nvidia, has declared A few days ago, China is not behind in front of the US in AI. And the solvency of Deepseek, Ernie, Qwen, Pangu, Hunyuan or Sensenova endorses its analysis. Right now it is very difficult to determine in an objective way which country leads in AI. It is reasonable to conclude that the US is ahead of China if we stick to the joint capacity and performance of its AI models, but the really relevant thing is to determine if that capacity entails a real value. This is The line of thought that defends experts As Arthur Lai, Chief of Research for Asia of the Macquarie Financial conglomerate, or Jason Corso, professor of AI at the University of Michigan (USA). In addition, it is important that we do not overlook that the metrics that are currently used to evaluate the abilities and performance of the most advanced AI models They are less and less clarifying. And as the models improve and develop their global competitiveness, it matches. Nvidia continues to dominate the Chinese hardware market for IA despite the sanctions of the US government In any case, as we are seeing, it is evident that China is competing from you to you in the development of large language models for the US. The greatest challenges facing this Asian country do not reside in this field; They last in the field of hardware. Nvidia continues to dominate the Chinese market of the hardware for the The sanctions of the US government that prevent you from selling your best GPU for your Chinese clients. And TSMC manufactures 90% of semiconductors for this scenario of use because it has in production some of the most advanced integration technologies that exist, and, what is also crucial, the performance per candy of its avant -garde nodes is very competitive. China needs to have companies capable of Compete from you with Nvidia and TSMCand their best candidates are currently SMIC (Semiconductor manufacturing international corp) and Huawei. SMIC is the largest Chinese manufacturer of semiconductors with a fee in the world market of about 5%and currently has the ability to manufacture integrated circuits of 6 and 7 nm. However, according to Dr. Kim, an expert in chips manufacturing who has worked in Samsung and currently investigating TSMC in the US, is about to start 5 Nm chip production and plan to start Its first 3 nod nodes equipped with gaa transistors (Gate-alall-around) in 2026. Huawei, meanwhile, is determined to absorb Little by little the market share that Nvidia maintains in China. Your most ambitious hardware is now the chip Ascend 910dthat pursues overcome performance of the GPU NVIDIA H100. However, this Chinese company has also recently presented its chip Ascend 920a solution that is clearly destined to occupy in the Chinese market the gaps that it will leave The H20 GPU of Nvidia. This proposal will enter large -scale production during the second half of 2025 using 6 Nm integration technology that have presumably developed side with Huawei and SMIC side.

Volkswagen was the infiltrated brand that reigned in China. Until it was rolled by a train called byd

by

China is eating the European car. Whether electric, hybrid or combustionit is increasingly common to see them in the streets despite the Tariffs imposed by the European Union. There are already A good number of available modelsto which we will have to add those of brands that have not yet finished landing. But that volume increase does not occur only in Europe: it also occurs within its market. And if we see the evolution of car sales in China, there are some absolutely demolving data that can be summarized in a Volkswagen who led with iron hand and could not see the great wave of byd. National upward production. It is evident that China has put the batteries producing cars. Taking the data From the Chinese Association of Automobile Manufacturers, in 2024 31,282 million vehicles were produced and 31,436 million were sold. This represents an interannual growth of 3.7% and 4.5% respectively. This has allowed China to maintain its position as the largest automotive market in the world, something that has held for 16 years. New energy. Within those figures, the production and sales of Nev vehicles, or New Energy Vehicle stands out. It is a term that It encompasses the electric, hybrids and electric with hydrogen fueland the production and sales relationship in 2024 was 12,888 and 12,866 million respectively. It represents an increase of 34.4% and 35.5% compared to the previous year and 40.9% of all sales of new vehicles in the country. The Byd sorpasso. To further break down the figures, 60% of that total sales of NEV vehicles correspond to the electric ones, being a sector in which a national brand has established itself at a meteoric speed: Byd. In this chart with the top 10 of sales of new vehicles per manufacturer we can appreciate how Byd did not paint anything in 2020 and, from 2021, he experienced a vertiginous ascent: China Oem #HorseracePay Special Attention to Byd & Geely!#AlwaysBecharging ⚡️⚡️⚡️🇨🇳🇨🇳🇨🇳Source: #Cam pic.twitter.com/4obu2vnj5q – Felix Hamer • Electricfelix (@electricfelix) June 2, 2025 No matter the metric that we follow. Month by month, the data of the Gasgoo platform lets us see that ByD leads in sales by brand or by manufacturer. They are figures that we could take from any month of 2024, but focusing on December, we can see that Byd is far from their main rivals: also Chinese Chery and Geely: December by Oems December by brand Byd 509,440 units 482,652 units Chery 283,903 units 174,430 units Geely 210,419 units 105,077 units Volkswagen can’t lose. In the graph we see that there is an absolute prominence of Chinese brands that They eat toast to Japanese like Honda or Nissan. However, there are two foreigners They stay well. On the one hand, Toyota, which although in third place, maintains consistent sales since 2017. On the other, the Volkswagen Group. According to CAM data for manufacturers, from sales of 4,192,356 vehicles in 2017, they go to 2,808,578. It is a monumental fall in an environment in which other brands are maintained or grow. Byd is the one that has stolen the first position and, although they remain in second place, you have to see what happens in 2025 with Groups as powerful as Geely. The German group is very involved in the Chinese market and in recent years it has launched plans to “copy” your work methods And even his approaches, Like extended rank electric. All with hope not to stay in a very important market for thembut not to lose more land in the European. IMPORTANCE OF EXPORTS. Because the idea of ​​Chinese companies is to continue tightening not already inside, but out of its borders. Saic, owners of Mg, They have the world’s largest ro-ro to bring their cars to international markets. It has capacity for 9,500 cars per trip and Byd also has a huge bureaucoches and the intention of add up to your fleet. As we see in Shanghai Metal Marketsince 2021, car exports have increased year after year. In 2024 they were 19.3% higher than in the previous period, reaching 5,859 million units, 433,000 were by, assuming a year -on -year growth of 71.8%. As we say, you have to wait to see the photo of 2025 already entered in 2026, but the trend of both sales and export of Chinese cars is up How will European brands respond And yes, despite all Byd is showing signs of weakness How can your latest sales aim.

Method 90-90-1 is the new religion of hyperproductivity. It is only common sense with mystical numbers

by

The 90-90-1 method was popular by Robin Sharma, the author of books like ‘The monk who sold his Ferrari‘. Sharma is not holy of my devotion – its self -help literature sins of industrial optimism typical of the genre – but the formula of this method starts from something reasonable, and that made me look at it. The proposal is dedicate the first 90 minutes of every day for 90 consecutive days to a single objective. Something that, he says, will transform your life. This formula is the last incarnation of our cult of personal optimization, wrapped in the seductive promise that happiness is just three months away. The formula is elegant in its simplism. Researchers from the University of Nottingham discovered that The self -control is at its peak just after awakeningand then gradually exhausted during the day, something that explains my strong sports discipline at dawn and my desire for dusk. Sharma calls the first hours “Platinum time“And he suggests that they are the optimal time to work on what matters most. The method is based on circadian rhythms and the theory of human chronotypes: Each person has natural moments of greater energy that can be used strategically. The interesting thing of 90-90-1 is in what omits: it is a psychological trick disguised as a system, not a complete methodology of time management. Sharma himself warns: “There is so much available distraction that, if you are not very careful, it will dominate your days.” So The method works not by revolutionary, but for forcing a behavior that should be obvious: concentrate on the important when we have the most mental energy. But there is a trap: if we concentrate for an hour and a half it is difficult, it is a common place in productivity literature to start with shorter blocks, and increase them little by little. If the mornings do not work, adapt it to another moment of the day. If you interrupt you, have a plan B. The 90-90-1 can become Xyz and that each one adjusts it to their convenience. But when something is so flexible that it adapts to anything, it ceases to be a method. It is rather a sophisticated excuse to do what we already knew we should do. 90-90-1 is not useful for its magical numbers, but for its function as a ritual of initiation to disciplineblessed word often shunned that in fact is not verbalized in a method dedicated to it. Like any productive fashion, promises personal transformation in exchange for willpower to follow a formula. Life is rarely bent before such orderly formulas. The objectives change. Priorities change. And rigid systems are usually the first to collapse before real life. 90-90-1 does not go as much to optimize our time as the collective need that someone tells us when and how to work on what matters.

Apple believed to have an excellent plan to deploy its AI in China. He is going as good as everything else in China

by

Souring records are precisely that, bittersweet. In Apple they know well: in the first quarter of 2025 124.3 billion dollars entered, but that colossal figure is fogged by a worrying fact: In China things are going wrong. The company is no longer what it was there, and has lost 9% market share in a year. In Cupertino, yes, they had a plan to relive sales: offer Apple Intelligence, and also do it with a category Chinese partner. Specifically, with Alibaba, which seemed the ideal option for its influence on the Chinese market and also for having a chatbot Especially advanced as Qwen2,5-Max. The plan was not bad, especially considering the worrying situation that Apple lives with its disastrous deployment of AI functions. Apple Intelligence is still far behind its competitors, and Siri’s scandalous non -zacing has revealed Internal rivalries, indecision and leadership problems In the company. But with Alibaba everything seemed good. The actions of the Chinese company rose like the foam after the rumors and everything seemed to go stern. It is not like that, and the deployment of Apple Intelligence in China with its new partner is delaying because of Chinese regulators. Apple and Alibaba have collaborated in the development of various AI products to be able to implement them, and have asked the authorities to regulate this sector to approve. But the administration of the cyberspace of China (CAC), main responsible for giving that blessing, has not done so. These requests are currently blocked According to sources close to the process cited in FTand reason is not technical, but political. The uncertainty about the situation between China and the United States and that commercial war that they maintain – and that affects the entire world – is causing that blockade, according to these sources. The situation for Apple is complicated On the one hand, he tries to deal with a US president whoUaiere forcing What Apple manufactures the iPhone that sells in that country locally. The idea is so expensive for Apple that will continue Going to account sEguir man by manufacturing them in India To avoid Chinese tariffs. On the other, it has been left behind for sale of iPhone in China, where Xiaomi, HuaweiOppo and alive have already advanced it. All of them have the government’s support and are tightening too In the supply of AI functions, but Apple Intelligence is still not a competitive proposal. Precisely the CAC approval process includes those AI tests. The AI ​​models developers themselves in China cannot market them or publish them unless they receive the approval of the government, which wants AI models “Very socialist“These restrictions should have favored Apple, especially after the alliance with Alibaba, but the tensions with the US after the absurd rise in tariffs -now in pause– They have made the situation unusual. The situation is so complex that Apple faces double suspicions. First, the final approval of the agreement between Apple and Alibaba to implement those functions of AI in the iPhone in China must be validated by the Chinese State Council. And second, the Bureau of Industry and Security of the US Department of Commerce has shown according to FT its reservations with that agreement, although they do not have legal means to prevent it. The situation is complicated, and that blockade of validation only becomes more. And meanwhile, Apple and Huawei grows. From the beginning of 2023 until now, Apple’s share in mobiles in China was 70%, and is now 47%. Huawei’s? It was 13% and is now 35%.

Five essential accessories in my switch that can not be missing in my switch 2

by

Throughout all the years in which I have used the Nintendo Switch I have been buying certain accessories that have become essential for me. Therefore, in the face of buying the Nintendo Switch 2 I want to continue using them or, for compatibility issues, buy the same updated or similar accessories for the new Nintendo console. And … What are these accessories? In this article I will review them. Hori Adventure Pack by 29.99 eurosa bandit compatible with the Nintendo Switch 2 that allows also to keep several games and accessories. Nintendo Switch Pro Controller by 64.99 eurosthe official Nintendo Switch command that is also compatible with Switch 2. Sandisk Microsd Express by 59.90 eurosthe MicroSD card compatible with the Nintendo Switch 2 to store data and games. Screen protector by 12 eurosa simple protector to place on switch 2. Echo Dot (5th Gen) by 63.99 eurosan intelligent speaker that I have used a lot with the Nintendo Switch. Hori Adventure Pack One of the accessories that I have used most with the Nintendo Switch is the shoulder Tomoc Compact X-Pacthat It has accompanied me many trips by train, subway and bus. It has been super useful to transfer the Nintendo Switch, in addition to certain accessories such as headphones, video games and even my ereader. Unfortunately, it is not compatible with the Nintendo Switch 2. Therefore, one of the bandits that I see more interesting is the Hori Adventure Pack (29.99 euros), which is compatible with switch 2, allows up to six games and some accessories. It is not too large, it includes a transport handle and a quite wide strap and allows a small padlock to the zippers. This is, of course, one of the accessories that I would prioritize, in addition to some that I will comment below. * Some price may have changed from the last review Nintendo Switch Pro Controller Although the Nintendo Switch 2 comes with the adapter to place the joy-with to be able to use them as a command, it is more comfortable to use a command, as is. In my Nintendo Switch I use the 8bitdo pro 2 and I loved all levels. It is very comfortable, the battery lasts a barbarity And he feels like a much more expensive command than it really costs. In the absence of knowing if this same command is compatible with the Nintendo Switch 2, I am clear that for the new console I would choose the Switch Pro Controller (64.95 euros). It is a control designed specifically for the original switch, so if you miss some functions and buttons (such as the “C” of the Gamechat or the rear buttons), it is possible that you want to opt for the Switch 2 Pro Controller (86.90 euros), although it is more expensive. Nintendo Switch Pro Controller * Some price may have changed from the last review Sandisk Microsd Express I am not a person who stores too many games on the consoles. In general, once I finish them. But in the Nintendo Switch I do have installed digital titles to play them at certain timesso I bought a card once 256 GB microSD. It has been enough for this storage capacity, but of course there are others of more size. These cards are not compatible with the Nintendo Switch 2. As mentioned Nintendo, for Switch 2 it is necessary to count (it is not mandatory except that we want more storage) with an Express microSD. These cards are more expensive and there are not too many offers. The 256 GB Microsd Express Sandisk has a price of 59.90 euros In Amazon. It is useful, above all, to have several downloaded games and not occupy all the internal storage of the console. Sandisk Microsd Express (256 GB) * Some price may have changed from the last review Screen protector A good screen protector can avoid the occasional scare, especially considering that Nintendo Switch 2 is a portable console (really hybrid). Having a screen protector can be useful in case we hit the console, but so it is When placing the console in the dock, since it can touch the screen. In stores we can find a great assortment of screen protectors, so … which one? I personally have these protectors very badly, so I would choose the brand Back (12 euros), since in addition to coming with a couple of rigid protectors, it includes a frame to align said protector to the Switch 2 Easy and simple screen. Two protectors pack with alignment macro for Nintendo Switch 2 * Some price may have changed from the last review Echo Dot (5th Gen) Yes, a Echo Dot (5th Generation). A few days ago I commented that I use the Amazon device with the Nintendo Switch Because almost always play in portable mode. In his day I wanted to try if the console could really be connected to Amazon’s smart speaker, and you can. Having a speaker is interesting if we usually play in portable mode, since We can have a better experience (quality and audio power). Echo Dot (5th Generation) * Some price may have changed from the last review Some of the links of this article are affiliated and can report a benefit to Xataka. In case of non -availability, offers may vary.

measure exactly the time they eat, according to scientists

by

Overweight is no longer an exclusive problem of adults or an isolated issue in childhood. Between improvised lunches and late dinners a serious problem is emerging. To follow the current inertia, a study Posted in The Lancet He has warned that Spain could be placed as the fourth country in the world with the highest prevalence of childhood obesity in 2050. And the answer is not only in what is eaten, but when. Looking beyond the plate. For decades, the nutritional debate focused on calories, Fats, sugars and Tags. But a key question had been out of radar: does the time it is eaten? Here the discipline of the Chrononutrition. This discipline analyzes how food schedules can directly influence our health. More technically, it is about biological watches (adjusted by factors such as light, sleep, physical activity and food) are closely linked to metabolism through the so -called circadian rhythms. Therefore, dinner late, that in Spain it is a usual tonic, it could be taking its toll. Not only does digestion hinder: it can also imbue metabolism, make insulin work worse and, over time, favor overweight, even if the dish seems healthy. Under that premise. A group of researchers from the valuenut project, from the Complutense University of Madrid, It was proposed to respond to that theorybut focusing on the little ones. To do this, they gathered 880 schoolchildren between 8 and 13 years old, from five Spanish provinces: A Coruña, Barcelona, ​​Madrid, Seville and Valencia. The goal was not just to know what children ate, but also what time they did. The study focused on three concrete aspects: breakfast, dinner and the “food window”. This little known concept refers to the time between the first meal of the day and the last to know how daily intake is distributed. The criteria? They considered late breakfast that occurs after 8:53 am, and late dinner that is taken from 9:10 p.m. If the difference between the two exceeded 12 hours, there was talk of a prolonged food window. The results. Unlike what They have suggested Some studies in adults, in this case there was no direct relationship between eating late or lengthening too much time between the first and last meal of the day, and neither was a greater risk of obesity in the children analyzed. However, the metabolism did give signals of change, such as the schoolchildren who had breakfast later presented lower levels of glucose and LDL cholesterol (the one known as “bad”), and higher in HDL (the “good”). A fact that revealed the thread that had to be thrown away. There was the pattern. When the late dinners or very prolonged food windows were analyzed, a different pattern emerged: the quality of the diet got worse. Less planned meals, more improvised and with less nutritional value. On the other hand, it was also given that there were children who ate the days for more hours, that is, with a longer window. These showed unavailable values ​​at glucose and cholesterol level and indices to develop cardiovascular diseases in the future. But there is more. And to this equation an additional factor was added: the dream. The study revealed that 60 % of these children also slept less hours, which could further enhance the negative effects on their metabolism. Less rest, more mismatch in food schedules and a lower quality diet: a silent, but potentially harmful cocktail. Synchronizing times. In the light of the results, the researchers launch a clear message: it is not enough to eat well, you also have to eat on time. From the study itself has clarified that the recommendation is to shorten the daily window, that is, that all meals are concentrated in a period of less than 12 hours. Of course, in the case of Spain, where late dinners are deeply rooted to culture, so the challenge is not less. However, if you want to stop childhood obesity, the “when” must occupy a place as relevant as the “what” and “how much”. The research also raises new lines of work: what role does the child’s chronotype play? What happens if this data is combined with sleep quality? What if it is also taught to better plan meals? Understanding how the internal clock works from childhood can be key to preventing this problem from growing with them.

There is so much demand for fish in China that has opted for drastic measures: two "aircraft carrier" as a hatchery

by

We already said it in 2022: China is hungry for fish. So much, that they have been accused of cleaning half -world folders. FAO says that almost a third of tons produced by world fishing They are related to China And hundreds of Chinese fishing have already been seen sweeping the waters of Peru. Beyond fishermen, Chinese shipyards are building huge ships focused on fish breeding on the high seas, endowed with the latest technology and hope: to help satisfy that Fish appetite. And they are so big that one of them has been nicknamed “fish breeding aircraft carrier.” Wan quing ding. This is the first protagonist. Thrown with success on May 27 (something of what North Korea could take note), the wan qu ling ding is the next great step of the aquaculture industry In China. As we read in China DailyThe Jiangmen Hangtong Shipbuilding Co. shipyard will deliver the ship to Zhuhai Ocean Development Group Co. in August and it will then be when it is mole 155.8 meters long and 44 meters wide can start producing. Beyond its dimensions, what attracts attention are Breeding pools. It has 12 independent compartments and has a capacity of 80,000 m³. This is equivalent to 32 Olympic swimming pools and this floating fish farm is expected to produce between 3,000 and 5,000 metric tons of fish every year. It is what a land fish farm of 3.33 million m² would do. In Xataka We are drugping the salmon with cocaine and anxiolytics. And that is causing them to behave strangely Intelligent aquaculture. The goal is for the ship to focus on the raven of species of high value in the Chinese market, such as the Golden Palometahe Seriola or the mereand it will be support for both internal and Tourism. To its dimensions and breeding capacity is added a water exchange system with the maritime zone in which it is located, something that helps increase the Fish quality. Each of the compartments has a system of sensors and automatisms that control everything. It has automatic food systems, but also something very curious. The swimming pools are semi -submersed in seawater and, if they detect Abrupt temperature changes in water o Contamination, those ‘swimming pools’ rise to reduce water resistance and that the ship can quickly move to safer waters. Almost total autonomy. Beyond their breeding capabilities, what attracts attention is autonomy. According to those responsible, electrical propulsion allows something they have called “autonomous maritime nomadism.” It has 2,000 nautical miles of autonomy and systems for autonomously navigateavoiding natural disasters such as typhons. You can also select the best waters of the breeding at all times and have equipped the wan qu ling ding with a Wind Generation System of 20 kW that can cover the entire electricity consumption of aquaculture systems. In this video we can see the Automatic and Water Filter system of a similar ship, the Guoxin-1: Your Hai No. 1. Almost in parallel, the Huangpu Wenchong shipyard of Guangzhou has built what they say is the first ship in the world dedicated exclusively to salmon breeding. His Hai No. 1 is a huge 250 -meter length ship and specializes in the salmon breeding. As in the wan qu ling ding, it has sensors and automatisms to quickly relocate in safer waters to Avoid pollution And, after a first test in April, it is expected to start working in June. Salmon independence. Its production capacity is imposing: up to 8,000 tons per year, with the ability to deliver Fresh salmon already processed in some national markets in 24 hours thanks to the built -in plant. And, even if it may not seem like it, this is the Hai No. 1 is of vital importance in Chinese geopolitics. The reason? As we read in SCMPit is estimated that more than 80% of salmon by Chinese consumers depends on imports. In 2024 they imported 100,000 tons and is expected to exceed 200,000 tons for 2030. Therefore, with large ships AquaculttersChina seeks to independent its fish supply and stabilize that chain in an international panorama that, as tariffs are demonstrating us, commercial relations can be truncated at any time. In Xataka A "stable macro" Floating: the ship that transports more than 75,000 sheep through the oceans And it is something that has become a national strategy, since the Ministry of Agriculture and Rural Affairs of China public In 2023 a series of guidelines to promote marine aquaculture.

China is moving whole buildings at the same time to build underneath. Because? Because it can

by

In China The buildings are. Literally. No matter how heavy and large that they are or if it is delicate brick and wood constructions raised a century ago. When it is necessary, the country’s engineers manage so that their houses are “lifted” and begin to “walk” slowly through the streets. It sounds crazy, but it is a technique that They have been polishing and allows them something key: respect their assets without stopping the development of parkings or commercial areas. The last example has left Shanghai, who has managed to walk A group of buildings which occupies 4,030 m2 and around 7,500 metric tons. Open step to the building. Chinese media, like People Daily, China Daily either Xinhuathey have been publishing these days a video and photos at least curious: in them it can be seen how a group of buildings, almost an apple, moves in block throughout several meters, just like in a huge game of tetris. Moveing ​​buildings is nothing new. In Spain it is also done. But the usual thing is that the architects are responsible for listing, disassembling and re -assembling the facades, do not displace entire buildings as if they were on a tape. Click on the image to go to Tweet. A figure: 7,500 tons. The block in question is formed by old Shikumen buildings Raised in Shanghai a century ago and their data give an idea of ​​the enormous logistics and technical challenge that involves moving them in a piece: According to the Chinese pressthe complex, known as “Huayanli” and which is composed of three brick and wood structures, measures 4,030 m2 and weighs 7,500 tons. The construction is found in Zhangyuan, in the Jing´an district, Shanghai. What have they moved for? To build under the ground. Chinese authorities decided to relocate that mole to facilitate the works of an underground three -story complex Zhangyuanan ambitious project, of just over 53,000 m2, which will include commercial and cultural areas, a parking lot with a hundred parking spaces and connections with several lines of the Shanghai meter. It is not the first time that China moves large buildings from one point to another. In 2024 We already told you which was displacing Shikumen housing raised in the early twentieth century in Jing´an. One of those blocks came to “travel” the a whopping 230 m, much more than other similar operations carried out before in the country, such as the temple of the Jade Buddha of Shanghai, which, which 30.6 m movedor the Hankau Yiyong Fire Association building, which 90 m slide On rails. But … why move them? That is the million dollar question. If the objective is to look for new locations or temporarily comply with the buildings while the operators work in the area, as is the case of the houses of Jing´an, why move them from a piece? Why don’t they disassemble stone by stone? Logistic, preservation and separate time issues, there is a fundamental element: Huayanli is built with brick and wood, in the line of the Shijumen buildingsan architectural style that emerged around the 1860s, closely associated with Shanghai and combines Western and Chinese elements. The idea of ​​engineers is to “lift it” without causing damage, move it and then return it to its original location, an operation that It is ready to complete. The key: 430 small robots. At this point the question is obvious … How have Chinese engineers manage to move a block of 7,500 tons houses? The key are 432 small robots. The company responsible for the work resorted to drilling devices that can be handled at a distance and move through narrow spaces, which facilitates work in the foundations. To avoid scares with collision points or structural problems, the team also handled Construction Information Modeling (BIM) and scan of points clouds, which allowed him to work based on 3D planes. I walk slowly, walk safe. Another of their resources was to use robots designed for the movement of land and endowed with folding mechanical arms that allow them to work in very small spaces, less than 1.2 m wide, also distinguishing clay or different obstacles. When it comes to displacing the constructions, the experts designed different routes. The task, of course, is not suitable for impatient: since May 19 Huayanli has mode 10 m per day.

Well, many things may probably happen, but what happened in 1956 was that those responsible for this extreme experience discovered a new species of bacteria. They discovered it for a simple fact: Deinococcus radiodurans It is a bacterium with enormous resistance to ionizing radiation. In his experiment, the team submitted the can to a Dose of 4,000 gray (gy) of radiation-γ. A radiation capable of sterilizing almost anything. At first, its discoverers baptized the species as Micrococcus radioduransbut decades of taxonomic work led to reclassify the species as a member of a new genre that was called Deinococcus. The new name of the bacteria: D. Radiodurans. Almost seven decades after the discovery of its first member, the strange family of the deinococcus already has 11 cataloged species. The “strange” is not a saying: the name of this genre comes from the Greek word “Deinos“, Which can be translated as” strange “or” unusual. “ Seven decades of study have allowed us to enter the mechanisms that D. RadioduransUse to get unharmed from exposure to ionizing radiation (it is estimated that the bacteria can leave “rositas” of Dose equivalent to 5,000 gy and get to survive even higher levels) and the breaks of the DNA chains that usually result from this type of exposure. This bacterium uses several “tricks” of survival that, according to An article Posted in 2005 in Naturecan be classified between passive, and active or enzymatic mechanisms. Among the passive mechanisms that this bacterium has, the fact that D. Radiodurans Porta with several copies of its genome and with a condensed organization in its nuclear body. Thus you can avoid the dissemination of DNA fragments generated upon receiving radiation, explains the signatory team of the article in Nature. Regarding active or enzymatic mechanisms, the article explains that this unicellular organism has processes for the Damaged DNA repair. Also how much with mechanisms that limit DNA degradation after receiving radiation. The study continues In the last 20 years we have continued advancing in the study of this strange bacteria. Last year without going any further, the magazine Proceedings of the National Academy of Sciences published a new article detailing a study that revealed new aspects of the resistance of this bacterium. The article studied the presence of a series of metabolites of this bacterium that, in combination with manganese, could form a powerful antioxidant agent. The team analyzed a synthetic version of this compound they called MDP, composed of manganese ions, phosphate and a small peptide. As they observedthe MDP components form a much more powerful complex when protecting against radiation than the compounds formed by the combination of manganese and the individual components of the MDP. The resistance of the bacteria can fascinate us but if so much attracts the interest of the scientific community is not only out of curiosity. Discoveries such as MDP antioxidant can help us protect our own radiation body and its effects. If we want to do long -term space tripsprotect us from Cosmic radiation It is essential; as it can also be to protect people who could be exposed to excessive radiation doses here on Earth. We do not know much about the origin of this bacterium but decades of study have given us enough information to rule out some ideas perhaps more typical of science fiction, such as the one that is postulating that it is an extraterrestrial organism or the fruit of the entry into the nuclear era. D. Radiodurans It is a bacterium, which implies a clear bond with the rest of the living beings of this planet and the evolution of its gender does not seem something that can occur in a few decades. The study of this bacterium, and of other similar will continue, either to satisfy our natural curiosity or to try to find new ways to protect us against radiation.

I have tried the Nintendo Switch 2 and I already have an answer to the question “Is it worth buying it if I have the original switch”?

by

Not every day a new generation of consoles is launched. Nintendo’s are complex to frame for a few years, but within their segment, Nintendo Switch 2 It is a new generation with all the letters. I’ve been a few days Testing the thorough switch For analysis and, between All questions that can be askedmany acquaintances have made me “Is it better to buy Nintendo Switch 2 now or wait?” Answering something like that has a lot of nuances because there is no perfect console for everyone and it depends a lot on the case, what you like to play or what other platforms you have at home. But a question for which I have a much clearer answer is another classic: “If I have a Nintendo SwitchIs it worth changing to Switch 2? “ Before trying the console, I thought it would only be worth it if the jump were going to give it from the original 2017 model, but These days with her have made me change my mind. This is going to be a more reflective text, as if I explained my ideas out loud, and I would love to read you in comments because an interesting debate can come out. A generational jump. Throughout I am a Nintendo Switch user from the launch of the machine. I bought it with ‘The Legend of Zelda: Breath of the Wild‘(Also Switch 2 start game) and, although the machine we are testing these days corresponds to a transfer of Nintendo, I reserved mine and is already in a house. During these eight years, I have played hundreds of hours to Switch, but from the launch it was noted that it was justice in power. The tegra chip that used was obsolete and, although Switch opened the door to the market of the Consolidated PConly Nintendo games and some exceptions had a perfect performance on switch. Then I had the model OLED For a time, and although in that the screen change (much better than that of the original model) and a more premium design, the performance remained the same. In these years, I have tried many games, and many of them with poor performance. Some exclusive titles were very bad and others, such as infamous’Batman Arkham Knight‘, directly They crawled into the console. Come on, a change was necessary. When they connect to the dock, although the resolution increased to show on the TV, the performance in many titles remained below the desired and the multiplatform versions were, in many occasions, objectively worse. As much (the case of ‘Hogwarts Legacy‘, for example, that looks like a game of another generation). When it was announced that Switch 2 was going to be retrocompatible, I stopped playing Switch 1 because I trusted that the performance of games that had no patch, simply by the increase in console power, improved. And it has been pleasant to verify that yes: the switching games 1 that crawled, Now in Switch 2 they are perfect. Image | Xataka This happens both in desktop and laptop mode, but there is something important to take into account: the games that previously were blurred, remain blurred in the new console because in many cases the resolution is not improved. It is something that shows in both modes, since now the dock gives 4K exit and the screen of the console has 1080p resolution compared to 1080p and 720p, respectively, of the first switch. From Switch’s embarrassing pin, we move on to a very good metal pin on switch 2. Image | Xataka And it is not just the power to play a lot of games that were impossible in the previous console (‘Cyberpunk 2077‘,’Yakuza 0‘ either ‘Street Fighter 6‘There are three examples) or exclusive releases such as the impeccable’Mario Kart World‘or the future’Donkey Kong Baniza‘, but Switch 2 feels much more premium than the previous console. Here, yes, there are nuances. If you come from an original switch, the jump is abysmal. The screen is much larger and better, the plastic of the Joy-Con is of more quality and with a velvety finish that feels great in the hands, the speakers have hit another climb, the support for the ‘tabletop’ mode is much better and, in general, everything feels more premium. The biggest joy-with a delight. Image | Xataka If you come from a Switch Oledyou will not receive such a large leap in terms of materials and screen (Switch’s OLED looks spectacular, but this Switch 2 LCD is not far behind), but you will have that extra power that feels great to the veteran console. A month ago, when We saw the console in the Paris eventI commented that Switch 2 seemed to me that It was worth only if you played in desktop. After seeing the performance improvements that put all the Switch 1 games, if you have a wide catalog of pending titles, now after trying it I consider that the jump between switch (both original and OLED) is worth both in desktop mode and in laptop. The new Switch 2 chip is not the pinnacle of technology, but Nvidia has been committed to him And this generation has something that did not have the previous one: the nuclei focused on AI for image reconstruction. Seeing what this technology can do on PC, when applied well, I consider it something that can give Switch a lot of life. I return to the case of ‘Cyberpunk 2077’: Thanks to these technologies, I think they have created A much better port than many could expect At first. If we talk about Switch Lite, the thing changes While now I am clear that it is worth changing from switch to Switch 2, if the console you want to jump is Switch Lite, I don’t have it so clear. Well, I am clear that I would wait for me. I explain myself. If you have Switch Lite It is because you want a strictly laptop console. That had no … Read more
