Cambricon Technologies is an essential company in China’s plans to challenge the US for its leadership in artificial intelligence (AI). Although it is not as well known as Huawei or Moore Threads, this is one of the companies specialized in designing GPUs for AI with greater growth potential. In fact, in August 2025 received approval of the Shanghai Stock Exchange (China) to raise $560 million for the design of four chips for training and inference of AI models, and also for the development of an alternative to CUDAfrom NVIDIA. Cambricon has notified, according to SCMPto the Shanghai Stock Exchange, which during the fiscal year 2025 has had a net profit of 2,060 million yuan (approximately 257 million euros). In the context of companies whose business is based on semiconductors and AI, it may seem like little money, but it is not if we keep in mind that it was founded just a decade ago, and also that it went public in 2020. In 2025 its income has increased by 450% compared to what it reached in 2024. Be that as it may Cambricon Technologies It is not China’s only great asset to deal with the US in the domain of semiconductors for AI applications. Moore Threads and MetaX Integrated Circuits They have also made known just four days ago an exceptional economic performance that has been driven by the growing demand for Chinese semiconductors in a context in which the Beijing Government seeks to achieve technological self-sufficiency. What China currently has and does not have The chain that supports the manufacturing of semiconductors for AI applications is complex, but China controls most of its links. On the one hand it produces approximately 70% of rare earths that are distributed on the world market, and, what is even more important, it controls 90% of the processing industry to which rare earths must be subjected so that they can be used. Furthermore, it refines nothing less than 99% of heavy rare earths of the planet. The rare earth They have a leading role in the trade, technological and geostrategic war between the US and China. These chemical elements are relatively rare, and, furthermore, they are not usually found in pure form in nature, but what makes them so special are its physicochemical properties. In fact, thanks to them they have established themselves as a very valuable resource in numerous industries, especially in electronics and renewable energy. Moore Threads has developed several GPUs for AI applications that rival some of the advanced solutions from NVIDIA, AMD or Huawei If we stick to the design of GPUs for AI, several Chinese companies are already producing competitive chips. Currently the flagship products that Cambricon has to compete with NVIDIA and Huawei in the Chinese market are the MLU series (Machine Learning Unit) and Siyuan. Moore Threads, on the other hand, has developed several GPUs for AI applications that, on paper, rival some of the advanced solutions that NVIDIA, AMD or Huawei have put on the market. The MTT S4000 and MTT S3000 cards are their most interesting proposals right now. The other indispensable player in the Chinese AI chip industry is Huawei. And their GPUs Ascend 910D and Ascend 920 They are receiving support from some of the Chinese companies that are developing AI models. In this context, the biggest challenge facing China is to develop its own cutting-edge semiconductor manufacturing technology. Or he will lose his fight for world supremacy with the US. Without 100% Chinese advanced chips, its military capacity, the development of its AI models and the competitiveness of its technology companies will suffer in the medium term. Huawei and SMIC are making advanced integrated circuits, but they use machines from the Dutch company ASML and a technology known as multiple patterning that compromises its competitiveness. This scenario has caused the Chinese Government support with very juicy subsidies to companies that have the capacity to develop cutting-edge photolithography equipment, such as YesCarrierShanghai Yuliangsheng, Shanghai Micro Electronics Equipment (SMEE), Huawei or SMIC. Time plays against this Asian country. Image | Generated by Xataka with Gemini More information | SCMP In Xataka | NVIDIA has to deal with the absolute distrust of several US legislators.

Europe has thought of throwing three robots into a volcanic lava tube and now colonizing the moon or Mars is closer

by

While the mission Artemis II Its objective is for human beings to return to the moon after more than half a century later, space agencies continue to investigate how to reach other planets and there space robotics is essential because well: space in general and places like Mars are the most inhospitable for life. So a European research group in which, among other entities, the European Space Agency participates, has introduced an autonomous robotic system inside a volcanic lava tube in Lanzarote, like collects this paper published in Science Robotics. Their conclusions bring us closer to a future colonization of the Moon or Mars. The context. Neither Mars nor the Moon have a flat desert surface, but rather they constitute volcanic worlds where there are underground cavities formed millions of years ago by liquid lava. We are not talking about small cavities precisely: there is space for a city to fit in as long as low gravity allows sizes of kilometers, how this study explains. Lava tubes are present on the Moon, on Mars and also on Earth, without going any further we can find some in Hawaii or the Canary Islands, precisely where the research was carried out: The lava tube of La Corona de Lanzarote has sections that reach 30 meters wide and high, come on, that It’s a cave like a cathedral. Why is it important. Because the space environment is harsh: there are extreme temperatures, radiation and meteor showers, a crude combination that makes it difficult for life to exist or simply to establish an eventual foundation for human civilization. On the other hand, if there is any remains of life or frozen water left, these caves are the ideal place to look for it. These structures are strategic because they function as natural shielding against ionizing radiation, extreme thermal flows and meteorites. So the next generation of robots will have the mission of exploring those underground lava tubes on Mars and the Moon to see what their conditions are like. The Lanzarote experiment. Anyone who has been to Lanzarote will know that it has places that seem taken from outer space. That is where the La Corona lava tube is where three different robots with different roles began their characterization mission without GPS or sunlight: The lookout stays outside mapping the entrance. The Explorer: It is essentially a cube full of cameras that you drop into the hole to look before anyone else. The speleologist, who rappels down to enter the darkness at a depth of 235 meters. The discovery. That they did 3D mapping as they progressed was just one of the objectives of this mission, led in the technical section by the German Center for Artificial Intelligence. But what is as important as how: the robots were not controlled with a remote control, but rather functioned autonomously, making their own decisions on the fly. Their performance in collaborative tasks is essential since in space the radio signal takes minutes to arrive from Earth. First Lanzarote, then Mars. The test carried out on heterogeneous and cooperative space robotics was a success, although there is still room for improvement regarding navigation without light and how the sensors respond to interference from the environment.

The electric car needs cheap batteries. And a Spanish region is closer to giving it to them: Extremadura

by

It’s just the go-ahead but it’s a key go-ahead. It is what will allow Yuneng International Spain New Energy Battery Material SLU to launch a project in Mérida to produce lithium iron phosphate (LFP/LiFePO₄). In other words, Mérida will be key to producing essential materials for the manufacture of LFP batteries. Batteries that aspire to be essential in the popularization of the electric car. Merida. It was the place chosen by Yuneng International Spain New Energy Battery Material SLU to build a factory that can produce lithium iron phosphate. The project will be located in the Expacio Mérida business park and will extend across 467,000 square meters after the Government of Extremadura has confirmed the approval of the environmental declaration for this factory. The project aims to have financing of 800 million euros and generate 500 jobs to produce the planned capacity of 50,000 tons per year of these materials. In the first phase they will mobilize between 116 and 125 million euros of investment creating about 160 direct jobs, they point out in Motorpassion. Why is it key? The production of lithium iron phosphate is essential for LFP batteries. Batteries are made up of modules and these, in turn, are made up of cells. In each cell there is an anode and a cathode. It is in the cathodes of LFP batteries where lithium iron phosphate sheets are located. Without them, the batteries would not work. In batteries of this type there are small lithium particles on the anode (negative pole). These particles move to the cathode (positive pole) through a liquid electrolyte found inside. This is when the electric current is generated which is then used by the motors to move the wheels. LFP Batteries. LFP batteries are one of the big promises of the electric car to make models cheaper and popularize this technology. It is a technology that offers less autonomy than NMC (cathode formed by nickel, cobalt and manganese) or NCA (nickel, cobalt and aluminum) because they have lower energy density. However, these batteries are cheaper because lithium and iron are cheaper than nickel or cobalt. And, in addition, they are safer and better resist load cycles so they will be more durable. This is essential for smaller cars, which will have less autonomy and must undergo a greater number of charging cycles but with the backpack of not being able to raise its price. Estremadura. In recent years, Extremadura has become relevant in the electric car supply chain. In addition to this lithium and iron phosphate production plant, in Navalmoral de la Mata (Cáceres) it is already rising a plant to produce complete batteries. This factory was designed to produce NMC batteries but has pivoted to produce LFP accumulatorsso both industries can be connected when the time comes. Additionally, the region is rich in lithium. Next to Cáceres it is believed that there are one of the largest deposits in Europe. The mine that should exploit this deposit has encountered the opposition from some neighbors and environmental platforms which has paralyzed the project. However, up to three of the seven projects that the European Commission wants to carry out in Spain for the exploitation of minerals and rare earths They are in Extremadura. The cheap electric car. To popularize the electric car, China has been betting on LFP batteries for years. In Europe, most electric cars have opted for batteries that include nickel or cobalt because they allow greater charging and discharging power and autonomy but are more expensive. Over the years, this has changed. Renault works with LFP batteries for the entry-level range of electric cars such as the Twingo or the Renault 5 (in the future). Tesla also uses them in the more modest versions of Model 3 and Model Y. In Spain, CATL is going to manufacture this type of batteries in Zaragoza for the smaller Stellantis cars. And Volkswagen too has this type of accumulator in mind for its most affordable electric cars that will come out of the Martorell line.

The burial of the A-5 is one step closer to ceasing to be a nightmare

by

The tunnel works that aim to transform the Paseo de Extremadura into the Paseo Verde del Suroeste in Madrid continue their course, with their last objective achieved: that of connecting the two excavation sections. Little by little, progress gives us a glimpse of the end of a work that is marking the day to day of thousands of neighbors during the last year. And if not tell it to our colleague Javier Pastor, who has been suffering from constant interruptions network as a consequence. Advance. Last Friday, the gap between two tunnel excavation fronts was completed, an operation that consists of connecting two separately drilled galleries to provide continuity to the underground layout. Thanks to this technical procedure, 700 linear meters of the tunnel are linked. According to reported Madrid City Council, to date 1.9 kilometers of the 5.1 planned have been excavated in both directions and 81.7% of the covering slab has been placed. This same process will be repeated in the coming weeks in the rest of the sections until the infrastructure is completed. The deadlines. The delegate of Urban Planning, Environment and Mobility of the Madrid City Council, Borja Carabante, counted to El Mundo that “the tunnel hole will be completed in April.” According to Carabante, from that moment on, paving work, installation of extractors, emergency exits and other technical infrastructure requirements will remain pending. The opening of the subway to traffic is scheduled for the end of 2026, so the initial deadlines are maintained despite the meteorological and logistical complications of the last year. Surface improvements. Just like they count From Diario de Madrid, since last Thursday, traffic entering or leaving the M-30 tunnel along Avenida de Portugal once again circulates in a straight line along 500 meters of the A-5, between kilometer points 3+250 and 3+750. Having completed the work on the covering slabs around the Amusement Park, it has been possible to recover the original layout without the detour. In addition, according to the media, a connecting branch of about 60 meters is being built between Avenida de Portugal and the A-5 to prevent traffic from being diverted onto Calle de Dante. The dark side. A year after construction began, residents are still dealing with significant disruptions. According to collect El País, the problems range from the deafening noise of machinery to water and electricity outages, to the deterioration of air quality due to dust from drilling. The president of the Batán neighborhood association, Arturo Sáez, resume The situation is seen in the middle as a “perfect storm”: the closure of the underpasses in August forced the activation of traffic lights and circular buses, while traffic to the Amusement Park and the Zoo collapses the neighborhood on weekends. Added to this are recurring internet outages due to damage to the fiber optics, the last of which has affected Movistar and O2 customers in areas such as Aluche, Campamento and Pozuelo. The ultimate goal. The work aims to transform the Paseo de Extremadura into the Paseo Verde del Suroeste, a 3.2 kilometer pedestrian axis that will connect neighborhoods in the Latina district (Lucero, Aluche, Las Águilas) with Campamento and Casa de Campo, separated since 1968 by the A5, on which some 80,000 vehicles circulate daily. The idea is that the coverage will reduce surface traffic by 90%, promising to reduce polluting emissions. It will also incorporate a 3.5 kilometer bi-directional cycle path, 33 new pedestrian connections compared to the current 16 and wider sidewalks. The project, with an investment of 408 million euros, seeks to continue the pedestrianized boulevard from Avenida de Portugal to Avenida del Padre Piquer. What remains to be done. The most complex challenge of the summer will be to execute the connection with the Portugal Avenue tunnel, which will force new traffic cuts similar to those of the last summer period. Borja Carabante assured that “the most difficult thing has already happened,” but acknowledged that diverting services such as gas, water, telephone or electricity continues to be a complicated task due to the age of the plans. The work maintains its pace with more than 600 workers and 400 machines operating simultaneously.

A 28-page US document has brought peace in Ukraine closer than ever. The problem is that it is the translation of a Russian text

by

And suddenly a 28 page document unpublished to date has suddenly entered as a missile in the negotiations of the war in Ukraine. Promoted by Washington, it has unleashed a diplomatic storm in Europe and in kyiv because, far from having been prepared with the main parties involved, it had been conceived in discreet negotiations between the American businessman Steve Witkoff and the Russian envoy Kirill Dmitriev, with the participation of Jared Kushner and the late endorsement of Trump. The origin of a plan. The result of these meetings was a text that Europe and Ukraine had not seen and that, to further alarm (according to one Bloomberg exclusive), preserved the linguistic structures typical of an original written in Russian, confirming the suspicions that Moscow had achieved filter your vision of the war in a document presented as a US initiative. The pressure exerted by Dan Driscoll (a close ally of JD Vance) on European and Ukrainian diplomats, urging them to accept territorial concessions in a matter of days, ended up setting off all the alarm signals. For European governments, which considered themselves central partners in any peace negotiations, the origin of the plan became a strategic question: they needed to know who had written it and with what objectives before sitting down to discuss. This information gap triggered a race against time to stop the imposition of a text that, in its initial form, was not only surprising for its demands, but also for its obvious alignment with Moscow’s interests. Territory, legitimization and a threat. The most explosive section of the American plan required that Ukraine will withdraw of the fortified urban centers that it still maintains in Donetsk, breaking the “belt of fortresses” that has slowed the Russian advance since 2014. This withdrawal would not only imply the displacement of tens of thousands of Ukrainian citizens, but it would open a corridor that would leave exposed to key cities like Dnipro and Zaporizhzhia. To make matters worse, the document proposed that the occupied areas be recognized as “de facto Russian”a more favorable formula for Moscow than the already problematic “de facto under Russian control”, and which, in practice, brought the international community closer to accept territorial changes achieved by force. Added to this was the idea of ​​converting the evacuated territories into a demilitarized zone whose violation by Russia (not an implausible scenario given recent history) would allow Moscow to open a new, even deeper offensive in the future. From the Ukrainian perspective, accepting this point would be sowing the conditions for a future war in worse terms, reinforcing the impression that the document did not seek a stable peace, but rather formalized a strategic result that Russia has not been able to obtain through military operations. Security cut and promises broken. The security guarantees included in the plan were vague to the point of irrelevance: they promised “reliable protection” without detailing mechanisms, but simultaneously prohibited Ukraine from entering never in NATOprevented the stationing of allied troops in its territory and forced kyiv to modify its Constitution to renounce accession. For a country marked by the experience of Budapest Memorandum (formal guarantees that prevented neither the annexation of Crimea nor the 2022 invasion), accepting an even more ambiguous framework would amount to to be left helpless facing an aggressor who has systematically broken all previous agreements. Red lines. The absence of a commitment type Article 5 and the refusal to allow training missions or deterrence forces on Ukrainian territory reinforced the conviction that Ukraine would be trapped between a strengthened Russia and a West that would reserve the right to “diplomatically support,” but not to intervene. This component fueled rejection in European capitals, which consider it essential that Ukraine keep an army strong as a land barrier that protects the continent. Limit to 600,000 troops to the only country in Europe at war, without imposing a similar restriction on Russia, was perceived as covert disarmament and a prelude to a future Russian offensive. Amnesty and frozen assets. One of the most shocking elements of the plan was the proposal of a general amnesty and Ukraine’s renunciation of any legal claim about war crimes, deportations or deliberate destruction of infrastructure. For an exposed population to documented atrocitiesthis clause meant not only the denial of justice, but also the elimination of the legal basis that allows Europe to advance the reparations loan backed by frozen Russian assets. That loan, of 140,000 million of euros, is considered by the EU as the more solid path and less expensive to sustain Ukraine during the postwar period. The US plan not only made it unviable, but also redistributed those funds in an unusual way: 100 billion would go to a US investment vehicle that would deliver half of its profits to Washington, another 100 billion would be contributed by Europe and the rest would go to a joint fund with Russia. For Berlin, Paris or Warsaw, the message was clear: Russia would obtain indirect financial relief while the Europeans would see their most effective tool of strategic pressure weakened. The attempt to force kyiv to renounce all moral and legal responsibility for the aggressor reinforced the perception that the plan sought to resolve the war “quickly,” not “fairly.” The Russian strategy. Since the beginning of the invasion, Moscow has not changed their fundamental demands: more territory in the east, military neutralization of Ukraine and permanent veto on its accession to NATO. This strategic immobility, together with gradual advances on the front, has allowed it to capitalize on Western fatigue, the political fractures in kyiv and transatlantic tensions. For the Kremlin, the leaked plan demonstrates that its commitment to prolonged resistance, military pressure and the erosion of Western will is bearing fruit. Putin openly celebrated it, affirming that the document could serve as a basis and that rejecting it would only lead to new Ukrainian defeats. Likewise, Moscow has hinted that even a signed agreement could be used as leverage to resume the … Read more

We had a very serious problem with our resistance to antibiotics. Now we are closer to solving it

by

One of the great threats that humanity faces today is without a doubt the antibiotic resistancewhich leads to emergence of bacteria that are resistant to all pharmacological weapons that we have. This forces science to have to look for new antibiotics and new ways to ‘attack’ a bacteria. And at the moment it seems that we are approaching this great milestone with a new antibiotic that was hidden in plain sight. The problem. Having bacteria that you cannot compete against is undoubtedly a death sentence for the person who is unlucky enough to be its host. Something that responds to the mechanisms that these microorganisms have to evolve and develop ‘tactics’ that allow them to escape our antibiotics. A very typical situation in a hospital, especially where a bacteria that has been exposed to a treatment, but has survived, will adapt to that environment. This makes the WHO categorize antimicrobial resistance as “one of the top 10 threats to global public health.” Put another way: we are running out of antibiotics that work, since bacteria are evolving faster than we are discovering new drugs. And this is something that is also magnified by our own fault by taking antibiotics uncontrollably or not complete treatment guidelines appropriately. That is why the discovery just made by a team from the University of Warwick and Monash University is so spectacular: have found a “silver bullet” that had been hidden in plain sight for 50 years. The discovery. Published in it Journal of the American Chemical Societywe are talking about an antibiotic that, in early tests, has been shown to be up to 100 times more powerful than existing drugs against high-priority resistant bacteria, such as feared Staphylococcus aureus methicillin resistant (MRSA). The molecule in question is called pre-methylenemycin C lactone (compound 5), and it has arrived to try to save humanity from this pandemic we are experiencing. But the most surprising thing is where they found it: in the Streptomyces coelicolora soil bacteria that is literally the “model organism” for the production of antibiotics and which has been studied endlessly since the 1950s. That is to say, we had a possible solution before our eyes and we had not realized it until now. This bacteria produces a well-known antibiotic called methylenemycin A that is low potency and is not used clinically. However, scientists decided to investigate not only the final product, but the intermediate steps of its biological “assembly line.” This is where it was seen that it intermediately produced methylenemycin C, which has much more powerful antimicrobial effects. And this is a lesson for science: we are always left with the result of the reactions (that is, the final product). But now what should be done is analyze everything that happens between the first substrate and the final product. Because we are seeing how methylenemycin A was discovered 50 years ago and it was not until now that one of its intermediate products has been a protagonist in this fight. As. To achieve this, the team used genetic engineering. Basically, they “sabotaged” the bacteria’s production chain by creating a mutation that eliminated the gene. mmyE. When this piece is missingthe bacteria could no longer complete the process and began to accumulate the “intermediate steps.” Something similar to when in a production line we remove one of the tapes and an intermediate version of what we were manufacturing begins to accumulate. The tests. When they tested the activity of the new molecule, the results were astonishing. Compound 5 (pre-methylenemycin C lactone) was “one to two orders of magnitude more active” (i.e., 10- to 100-fold) than methylenemycins A and C (the final products). In this way, it was finally possible to see that the result was up to 256 times more powerful than even some drugs. Something that is revolutionary. The great hope. Being powerful is all well and good, but the real battle is against resistance. That is, when the bacteria come into contact with this antibiotic, they can develop a system to get rid of its lethal effect. And this is where there is good news, since after subjecting the bacteria E. faecium At increasing concentrations of the new antibiotic for 28 consecutive days, a standard method for forcing the emergence of resistance, no resistance was detected. A new way to search. Until now, the intermediate products generated in the production of different medicines had been ignored. Now this study puts an end to this custom, since it has become clear that the identification and testing of the intermediate elements of biosynthesis can lead to a great revolution. Now with this new treatment, preclinical tests with animals remain to assess its safety with the aim of subsequently moving on to tests in humans and the evaluation of its side effects.

29 years ago we clone to the Dolly sheep. Thanks to this, today we are one step closer to solving the fertility crisis

by

Imagine a future in which the infertility caused by the lack of ovules or sperm is no longer an insurmountable obstacle. A future where two men can have a biological child together, or where A woman who has lost her ability to produce ovules For age or for a cancer treatment may have offspring with its own genetics. This future, which until now belonged to science fiction, is a little closer thanks to a revolutionary advance that has been published in Nature. Biology This advance, which seems like a science fiction, has been made by the team of researchers at Oregon Health & Science University, led by Dr. Shoukhrat Mitalipov. In this case they have managed to develop an experimental technique that forces a skin cell (somatic) to reduce your number of chromosomes in half. It is, in essence, the most crucial and complicated step in the creation of a gamete (an ovule or a sperm). A process they have called mitomeiosis. To be able to understand it, you have to know that all the cells of our body have in total 46 chromosomes in its nucleus. But there is an exception: sperm and gametes that They have 23 chromosomes. A very important number so that when an ovule and sperm merge, they have a total of 46 chromosomes. That is why it is revolutionary that they have managed to get a skin cell to have 23 chromosomes to be an ideal candidate to give offspring. The trick. The natural process to create these haploid cells (with 23 chromosomes) is called meiosis. A very complex type of cell division that has been investigating for a long time. This made it replicate in a laboratory, which is known as in vitro gametogenesis (IVG) was one of the greatest challenges of biology. Something that now reminds us of what we already saw with the Dolly sheep in the cloning process. OHSU’s team addressed the problem in an ingenious way. Using a technique similar to cloning, called nuclear somatic cell transfer (SCNT). A technique that is complex, but can be summarized in three different steps: The first thing is to take a donated human ovule and extract the genetic material. In this way, the ovule maintained all its cytoplasm with the organelles, which ultimately is like the machinery that the cell has to produce energy and carry out many processes such as meiosis. Once done, a skin cell is taken (a diploid cell with 46 chromosomes in a 2N state) and is extracted the nucleus inside. Now it only remains to introduce the core of the skin cell into the ovule that has been emptied. The result. In this case it was amazing, since the ovule cytoplasm could ‘deceive’ the skin’s core, forcing it prematurely into a state similar to the metaphase of the Meiosis. This caused its 46 chromosomes to be organized in a spindle ready to divide, despite having skipped the DNA duplication phase in the cell cycle that is before the division of the genetic material. The problem. However, here they met a wall. In nature, the entrance of the ‘active’ sperm to complete its division, being mediated by a large number of zinc. But in this case, when they tried to fertilize the SCNT ovules with sperm, the vast majority (almost 77%) remained ‘arrested’ without reacting. The natural signal was not enough for this artificial construction. The solution in this case went to develop an artificial ‘starter’ key. After sperm fertilization, they applied an assisted activation protocol an electrical pulse by electroporation to simulate the calcium entry caused by sperm to its entrance, followed by a treatment with a chemical inhibitor called Roscovitin. And it is something that ended up working. Forced activation made the modified ovules leave their arrest and complete the division. The 46 chromosomes of the cell were separated, leaving an average of 23 chromosomes within the fertilized ovum (now a zigoto) and expelling a small polar body from the rest, having achieved the long -awaited ploidy reduction that was the objective of this experiment. Progress. The embryos resulting from this experiment containing chromosomes of the skin and sperm cell, beginning to divide and even some reached the blastocyst phase (an early development of about 5-6 days), with a success rate of 8.8%. This shows that genomes can integrate and work together. It’s just a test. The authors who are still a long way forward, since for now it is a “proof of concept” by not being a perfect replica of natural meiosis. In this case, segregation is random unlike meiosis, where it is ensured that each daughter cell receives a copy of each of the 23 types of original chromosomes. In this project the separation of homologous chromosomes (the paternal and maternal) was completely random. This generates aneuploid embryos that are incompatible with life. In addition, it also lacks ‘cross -rise’ or crossovera vital mechanism in meiosis where paternal and maternal chromosomes exchange fragments creating genetic diversity. This is something that is not present in this process and that takes away a lot of variability. The future. Despite the limitations of this study, work is a fundamental milestone. It aligns with other laboratories such as the Japanese Katsuhiko Hayashi that in 2023 managed to create functional ovules From male mice skin cells, with which healthy offspring were born. In the long term, the implications of these studies give hope to those women who suffer from infertility due to lack of functional gametes and who want to have offspring with their own genetics. The same happens in same -sex couples that also open the door for a couple of men (using a skin cell to create an ovule) or women (creating sperm) can have biologically related son between both members of the couple. Although we cannot also forget that right now there is a fertility crisis that causes that in Spain, for example, there is reduced birth rate. This is also conditioned that it is … Read more

that Russia is getting closer

1,300 kilometers from the north pole is the town more northern inhabited of the world. We refer to the Norwegian people of Svalbard, an extreme region, a gigantic ice cream, much above the Arctic Circle where 2,500 people officially have Forbidden to die. And yet, what worries them most has nothing to do with their climate or geographical place. What worries them most is that Russia is getting closer. Forbidden to die. It We have counted. In Svalbard one of the most peculiar rules on the planet governs: it is Forbidden to die In Longyearbyen, its capital, because the permafrost prevents the decomposition of the corpses and preserves viruses and bacteria for decades, which was already checked when bodies buried in 1918 still contained traces of the Spanish flu virus. Since 1950the cemeteries stopped accepting deceased and any seriously ill or elderly person must move to the continent to spend their last days there, while the few still visible burials are vestiges of previous times. The rule reflects both the hardness of living in the Arctic Like fragility of a settlement where life, and even death, is conditioned by ice eternal. The new Arctic border. I told the weekend Bloomberg. On the top of the island of Spitsbergen, in the Svalbard archipelago, Raise Svalsatthe largest earthly satellite station in the world, with 170 domes that connect every few seconds with satellites in polar orbit and provide critical data for weather, navigation, climate research and maritime security.

Norway sees it as a Sovereignty symbol And it has expanded with energy and communications projects, collaborating with agencies such as NASA, ESA or Oneweb.

In practice, it represents A strategic symbol For Moscow in the Arctic. After the invasion of Ukraine, the relations between the Norwegian and Russian communities cool: They canceled visits Tourist to Barentsburg, joint sports activities were suspended and many Ukrainian miners returned home.

The transition from an industrial past to a post -mimine economy leaves open questions: What will replace mining, how much tourism can be allowed and how to sustain a diverse population without causing internal tensions. The Life in Svalbardmarked by polar bears, mortal avalanches and the lack of maternity or geriatric centers, remember that there everyone lives in time borrowed. “ A global rivalry.

With the accelerated thaw opening routes such as the passage of the northeast and multiplying the strategic value of resources and communications, Svalbard emerges as a microcosm of the worldwide struggle: A place where science, defense and trade are intertwined with political symbols and sovereignty shocks. For Longyearbyen residents, the transition has been palpable: from a mining people cohesive to a community exposed to global currents that generate diffuse identity and tensions with their Russian neighbors. As expressed A veteran resident, even in the coldest times of the cold war, local cooperation persisted. Now, that coexistence also seems lost, leaving Svalbard in the awkward first line of a new era of Arctic Competition. Between tourism, science and climate. Plus: the mines It raises an economic vacuum that only partly They fill tourismincreasingly massive with the arrival of cruises, and scientific projects such as World Seed Bankwhich barely offer employment. Meanwhile, Arctic heating, four times faster That the global average melts permafrost and compromises infrastructure, makes energy more expensive and multiplies natural risks. The dilemma of how much tourism growth accept, how to attract permanent families and what role in global research defines the next Svalbard stage. And in the midst of these tensions, the inhabitants try to maintain their identity and resilience, aware that they live in a territory where nature and Geopolitics They weigh as much as the will of their own residents.

Intel is closer than ever to be chopped. A giant is interested in buying its chips factories

by

The possibility of intelid for a long time. Two years before get out of this companyPat Gelsinger, the former Director General of Intel, He acknowledged that he saw with good eyes The possibility that the network of integrated circuit factories is somewhat broken down from the company’s matrix. At that time, More than three years agothis was already an interesting option to increase the competitiveness of its chips production plants, and in current circumstances it seems even more advantageous. At the beginning of last April Reuters and The Information assured that the Board of Directors of Intel and TSMC had reached a principle of agreement that was pursuing to constitute a joint company that would be responsible for the management of Intel semiconductor factories. Its plan was that TSMC would have a 20% participation in the new company, so presumably Intel would maintain a majority participation. Finally, this initiative did not come to fruition, but the possibility of splitting the Intel chips factories of the company’s matrix is still on the table. And now it is the Japanese investment group SoftBank who, According to Financial Timesis interested in controlling the Intel Integrated Circuit Production Infrastructure. SoftBank has something very important: the support of the US government As we explain yesterday, SoftBank has injected into Intel 2,000 million dollars, which has consolidated it as the sixth main shareholder of this company. According to Reutersthis Japanese company has promised not to participate in the Board of Directors, and it will not buy integrated circuits produced by this American chip manufacturer. However, SoftBank’s plan does not end here. And is that, According to Financial TimesMasayoshi Son, the general director of this investment group, is interested in Intel chips factories. SoftBank has promised not to participate in the Board of Directors of Intel In fact, again according to this means of communication of British origin but currently in the hands of the Japanese company Nikkei Inc., before formalizing the injection of 2,000 million dollars in Intel, SoftBank communicated to the board of directors of this company its interest in its interest in Buy the full semiconductor production subsidiary. A priori it is reasonable to anticipate that the US government would not see with good eyes that a foreign company is done with the total control of Intel chips factories, but SoftBank is not any company. The most important initiative of how many has launched the Trump administration to protect US leadership in the field of artificial intelligence (AI) is The Stargate project. And this plan is led by an American company, Openai, and another Japanese: SoftBank. The company directed by Sam Altman is responsible, in broad strokes, for the development of technology and infrastructure management. And Masayoshi’s company are responsible for financial administration. Stargate will cost no less than 500,000 million dollarsand it is evident that the US government Trust SoftBank. During the next few weeks we will check if the purchase of Intel Prosper Chips factories, but all likelihood the administration will not be an obstacle.
