China has given the green light to buy NVIDIA chips. The problem for your companies is that you will closely monitor each operation

by

NVIDIA has hundreds of thousands of H200 chips trapped in limbo. It is one of the company’s most powerful chips and the standard of the companies that are training AI. It is preferred for train the modelsand also the weapon with which The United States sought to leave China out of the game. After movements by the two countries, The US finally approved (25% commission through) that NVIDIA could sell the H200 to Chinese companies. China has taken some time, but finally it seems that it will accept the offer reluctantly and with an ace up its sleeve: DeepSeek. The mess. The H200 issue is a soap opera. In the context of the trade and technology warthe United States played one of the best cards they had: preventing one of their most powerful products from reaching Chinese hands. They also hindered European companies like ASML from selling their most advanced machinery for making semiconductors to companies like Huawei or SMIC. China responded, of course. He attacked with rare earth -that control almost exclusively– and has been showing little by little that they can not only create advanced semiconductors on your own (and pushing old technology to the limit), but they are alive and well in the battle for artificial intelligence. Furthermore, they have developed a robotics industry and other aerospace practically out of nowhere, making a vacuum to Western chips, and that has caught the United States on the wrong foot. China makes a move. Seeing that China was advancing and the US was not getting a cent, they moved tab: They opened the door for NVIDIA to sell its H200s to certain Chinese customers. For each sale, the US took 25%, but it seems that it was something that the Chinese Big-Tech wanted to take on because they need, at least currently, that NVIDIA technology. And the GPU company itself increased production expecting two million orders above normal. The problem is that everything moved very quickly. without China, really, having said anything. Because here it is not just a question of whether the United States lets it sell, but whether China wants its companies to buy. In a tense calm that left requests halted and thousands of H200 in limbo, China has finally made a move. According to Reuters, and as we told a few days agothere are companies that will be able to place orders for the H200. There is a “but”. It is not carte blanche for anyone to place an order. According to WSJ, Chinese authorities have indicated that each purchase must be for a use considered “necessary.” That includes advanced research or development in AI. Because two factors come into play here: On the one hand, it seems that there are Chinese companies that are pressuring the Government to let them access the technology. NVIDIA was allowed to sell the H20 to Chinese customers, but if these customers can now buy the H200 – six times more capable – they want to take advantage of it. But China does not want everyone to throw themselves into the arms of NVIDIA because, precisely, they have been building their own semiconductor industry for five years with SMIC and Huawei in the lead. China’s goal is to stop depending on the US, and if everyone starts buying US chips like crazy, they will not advance on the technological roadmap that the country marked a long time ago. That is to say, it seems that Chinese regulators are going to evaluate which companies can or cannot buy the H200 depending on the use they want to give it. It has been reported that, for example, ByteDance, Alibaba and Tencent will be able to import 400,000 H200 chips. But there is a twist to all this. deepseek. China’s quintessential artificial intelligence model is one that has turned both NVIDIA and the United States upside down. The question was how it was possible that, without access to the latest technology, DeepSeek could optimize its AI so much. On the one hand, ingenuity to circumvent the CUDA standard. On the other hand, there are those who are clear that DeepSeek has been trained with NVIDIA cards… smuggled. Accusations of smuggling are nothing new in this commercial and technological war, but precisely, and according to Reutersthe company that joins NVIDIA’s massive H200 order along with ByteDance, Alibaba and Tencent is… DeepSeek. Officially, and without restrictions, they will be able to access the H200. “We have given China the argument to launch its own industry and, at the same time, we are giving them access to ours again” – Samuel Bresnick Whiplash. I really liked this concept that Wired uses to define American policy in this regard. They are the ones who started the conflict and their position has been pivoting about tariffsbut with more or less lax measures depending on the moment. It seems clear that, now, they are at a point where they have had to think “if China is going to somehow reach the technology, at least we sell it and earn something along the way.” Samuel Bresnick is a researcher at the Georgetown Center for Security and Technology and comments in Wired that the worst thing you can do is “come and go,” noting that “we have given China the argument to launch its own industry and, at the same time, we once again give them access to ours.” Get your batteries. And meanwhile, there’s Jensen Huang. The CEO of NVIDIA has taken a mass bath in recent days in both China and Taiwan, where he has met with some of the companies that move the semiconductor sector. NVIDIA sat at the same table, TSMCFoxconn or Asus, and Huang came out, half joking, half seriouswith one request: you need wafers and RAM. Regarding the purchase of the H200, China is walking on eggshells, and it makes perfect sense. It is at a point where it does not want to be left behind, and to do so it needs its … Read more

We knew that smell and memory are closely related. And that unlocks an advantage: detect the Alzheimer’s

by

Alzheimer’s disease may be difficult to detect. The symptoms of this disorder usually become evident only after the progress of this dementia, which is a huge problem. And, in the absence of a definitive cure, our ability to stop the impact of the disease depends largely on early detection. Smell. One of the clues we have when detecting Alzheimer’s in its early stages is through smell. A study conducted by researchers from the University of Chicago analyzed the impact of the disease on our sensory capacity and detected that there is a rapid loss of smell when making us greater could predict with some accuracy The advent of Alzheimer’s disease. Smell of Magdalena. The relationship between memory and smell is very narrow. We know that the evocative capacity of smells It did not go unnoticedbut in recent decades science He has been confirmed This unique connection. The reason for this close relationship can be anatomical. The olfactory bulb is the region of the brain that processes in the first instance the smells and then send the signal to other areas of the brain. This signal crosses key areas of the limbic system, areas linked to emotions and memory. “The olfactory signals reach the limbic system very quickly,” Explain to The Harvard Gazette Venkatesh Murthy, head of the university’s cell and molecular biology department. 515 participants. The study of the University of Chicago had 515 participants, advanced adults, registered in the memory and aging project of the Rush University. These participants were examined annually, exams that test their cognitive abilities to detect signs of dementia. These tests also studied their ability to identify odors, in addition to other health -related parameters. More than memory loss. The team thus found a new link between smell and memory: a rapid loss of olfactory capacity prior to any cognitive loss could predict the arrival of various symptoms associated with Alzheimer’s. These symptoms included a lower volume of gray matter in the areas of the brain linked to smell and memory, cognitive loss and a greater risk of dementia. They also found a relationship between this olfactory loss and the presence of the APOE-E4 gene, a genetic variant considered risk factor in the advent of Alzheimer’s. The details of the study were published In an article In the magazine Alzheimers & Dementia. “This study provides another clue on how a rapid loss of the meaning of smell is a very good indicator of what will end structurally in specific regions of the brain,” ” explained in a press release Jayant M. Pinto, co -author of the study. Get ahead of the disease. Alzheimer’s is an incurable disease for now, but there are different treatments that allow us to delay the development of its symptoms. For that, we must get ahead of the disease as much as we can. Something difficult in a disorder that only shows its consequences once the disease is advanced. “If we could identify their 40, 50 or 60 people with greater risk, we could potentially have enough information to aim them in clinical trials and develop better medications,” also added in a press release Rachel Pacyna, work caoautora. Own initiative. The fact that the change in our smell is rapid and before the arrival of cognitive deterioration opens an important window, putting the patient itself in warning. And it is that most of the ways we have to detect the appearance of dementia is through external evaluations, for example when family members detect memory problems or In language. The loss of smell is something that, in principle, It can be striking to the patient himself and put it on guard or encourage him to seek medical advice. When the smell of the Magdalena stops bringing us memories, perhaps what we are playing is not only the evocation of a memory. In Xataka | We have a new “theory of all” to understand Alzheimer’s.

Sweden has managed to be 100% recyclable and turn its waste into energy. Spain follows it closely

by

More than 190 million tons annuls of urban waste are generated in Europe, according to The European Waste Association. This amount of garbage has increased greenhouse gas emissions, contributing to climate change. However, to deal with recycling is not enough, but some countries have found a way to generate energy. 100% recycled. One of those countries and precursor has been Sweden, which They have found In the incineration of waste an energy source, providing heating and electricity to 250,000 homes. Energy source. The data, provided by the Swedish state company VattenfallThey have indicated that only 1% of the trash ends in landfills; The rest becomes energy through the use of biomethane. Thanks to this energy source they can generate heating, electricity and even can be used as fuel for cars. In addition, the Swedish nation is importing the waste from other European countries to produce more energy. The process. Waste management in Sweden It is done In plants Waste-to-Energy (WTE). Once there they are divided into three categories. The first is the organic garbage that is transformed into biogas, compost and fertilizers. Then the plastics that end up recycling. Finally, all non -recyclable waste is incinerated at temperatures up to 850 ° C to generate electricity and heating. And in Spain? A recent report, which has had access Infobaesaid that the Spanish nation will not meet the waste management objectives established by 2025. In it they have stressed that the waste sector is responsible for 5% of greenhouse gas emissions. But are they taking action? The central government has proposed to implement A packaging system, in which citizens will receive a refund for recycling containers. For its part, the Valencian Community will reuse The waste and mud that left the Dana, and is studying the possibility of incinerating them to generate electricity. But there was not an ace under the sleeve … Spain has A great potential To develop the biomethane industry, a renewable gas similar to natural gas that can be stored and injected into the current network. However, as indicated Cecilia Carballo for Fifodiesthe country is behind other European countries in terms of facilities. However, there is a glimpse of hope if appropriate support is given, Spain could take advantage of its ability to produce up to 160 twh per year, which would cover 50% of the national natural gas demand. For this, a robust regulatory framework and policies that foster their development are necessary.

Although experts see no signs of an eruption, they insist that it must be monitored closely.

by

Over the past few years, and especially this past week, Teide has been attracting the attention of experts and locals alike. The reason is that this dormant giant has been showing signs of activity for a few years. Activity, which, these same experts point out, should not lead us to think that an eruption could be near. “Anomalous” activity. The scientific team in charge of monitoring the state of Teide has detected some “slight” changes to this one. This is an increase in carbon dioxide (CO2) emissions and a deformation of the land. The information emerged after the meeting last week of the scientific committee of the special civil protection plan for volcanic risk in the Canary Islands (Pevolca). No risk in the short or medium term. The team emphasize that this does not imply an imminent eruption, not even close. For this reason, they clarify, it is not necessary to move to the yellow seismological risk alert level. “It is important that people understand that this is not the situation we experienced on La Palma before the eruption,” explained Itahiza Domínguez, director of the National Geographic Institute (IGN) in the Canary Islands, in statements collected by the agency EFE. Precursors. For now, Teide has not given the type of signs of activity that could be linked to the arrival of an eruption. As explained by the IGN itself, basaltic-type eruptions such as the one that would be expected in this volcano are preceded by “very strong” precursors of seismicity: the deformations of the terrain and the emission of gases would be accompanied by intense earthquakes and swarms. “very dense” of seismic activity. Domínguez recalls that the island of Tenerife is “volcanically active”, which implies that an eruption is possible at some point in the future, but we still do not have any signal that tells us when it could occur. Since 2016. The observed rebound in the island’s geological activity it’s not entirely new. Starting in 2016, the experts who monitor this activity began to observe an increase in the volume of CO2 expelled by Teide accompanied by an increase in the microseismicity of the environment. Nemesio Pérez, director of the Canary Islands Volcanological Institute (Involcan), spoke of “significant changes” that have occurred in the last eight years. Clarify, however, that this does not mean that they are changes towards an eruption.” More surveillance. Last week’s meeting served to emphasize the need to reinforce surveillance of the volcano under the highest peak of the Canary archipelago (and the rest of the country). “We do not see a magma movement per se, but we must monitor it,” Domínguez pointed out to EFE.

China is closely monitoring the United States movement with Stargate. And your answer has already prepared

by

The US government led by Donald Trump is determined to lead in the field of artificial intelligence (AI) cost what it costs. And in principle this initiative, baptized by the new administration as ‘Stargate project’it will cost 500,000 million dollars. This money will leave the coffers of the Japanese investment group SoftBank; of those of OpenAI, the creators of Chatgpt; of those of Oracle, and, finally, it will also be provided by the investment firm Emiraratí MGX. These companies will support the construction during the next four years of an advanced data centers that will house the high performance computing infrastructure necessary to keep the US at the head in the field of AI. Interestingly, the spearhead of these facilities is already being built in Texas (USA). For China, this ambitious US project represents a threat to the same extent that for the country led by Donald Trump Chinese advances in AI constitute a problem. China’s response is already underway The administration headed by Xi Jinping has rushed to make the US know that its Stargate plan will receive an answer from your country. “China has made impressive advances in the construction of smart computer centers. While maintaining the current rhythm, the gap in the field of computing infrastructure that separates them from the US will be reduced even more … despite the Stargate project,” has declared Lian JyeChief analyst of the British consultant OMDIA. China has advanced a lot during the last 24 months in the field of high performance computing infrastructure SANCTIONS TO CHINA deployed by the US and its allies During the last two and a half years they pursue the development of their semiconductor industry, and Also from its AI infrastructure. In the field of integrated circuits Chinese manufacturers face the enormous challenge of producing their own equipment from extreme ultraviolet lithography (UVE) necessary to be able to manufacture avant -garde semiconductors. However, in the field of Chinese high performance computing infrastructures it has advanced a lot during the last 24 months. In fact, Official data They reflect that in June 2024 they were recently finished or under construction at least 250 advanced data centers and other computer facilities in China. According to the Chinese Academy of Information and Communications Technology, the country led by Xi Jinping is only behind the US. Although This source is interestedhis conclusion is very credible. “We hope that China significantly increase its investments in AI and semiconductors in response to the US domain in AI,” CBM consultancy analysts foresee. It makes sense. These two great powers world supremacy are being disputedso it is understandable that each significant step that give one of the two Receive a more or less overwhelming answer from the other. We can be sure that 2025 will be a year even more agitated than 2024 in the geopolitical and technological fields, so we will be attentive to the steps that US and China will surely give.
