We have been discussing the change of time for years and we have managed to be in exactly the same place where we were

by

Almost every year for almost 20, Someone has taken To the United States Congress the idea of ​​ending the change of time. In Europe, We have spent hours and hours engaged in the discussion of what to do with him. Many countries, in fact, They have sent it to the history drawer (Others, on the other hand, They have recovered it again). I am still surprising that such a simple thing can unleash such great passions. Passions and, above all, reasons. Because there are hundreds of researchers trying to understand which time policy is better. That is why we talk about it again: because the Internet has filled with holders that ensure that “a study reveals that the change of time contributes to thousands of brain infarctions.” It’s true? What do we really know about the subject? How can the time change affect our health? The body has an internal clock of (approximately) 24 hours that helps regulate our physical and mental functioning. And not, It is not a way of speaking: As is in charge of innumerable physiological processes, the time we eat depends on that clock, to which we sleep, it even determines when we go to the bathroom. Ignore your permanent tick can cause discomfort or even a certain moment, serious diseases. Is What we call circadian rhythm. With this in mind, during this century, scientists have suspected that the hourly change should have some impact on those rhythms and, moreover, on health. The problem is that one thing is to intuit that impact and a different one is to be able to prove it. And what has this last study done? Stanford Medicine researchers They have compared how they affected circadian rhythms and general health in different different time policies (the winter schedule, summer and schedule with biannual change). To do this, based on the local exit and sunset hours, they analyzed the real exposure to the light under each time policy, the circadian impacts and the socio -health characteristics of each American county. It is not easy and has a high statistical component (and, in some segments, speculative), but it is an interesting exercise What have you discovered? In general terms, The team found that “maintaining the standard schedule or summer schedule is definitely better than changing twice a year.” According to their data, the winter schedule “would avoid about 300,000 cases of stroke per year and reduce obesity in 2.6 million people.” The summer schedule, meanwhile, “permanent would achieve approximately two thirds of the same effect.” And why would it happen? “When there is light in the morning, the circadian cycle is accelerated. When there is light in the afternoon, it slows down … explained Jamie ZeitzerProfessor of Psychiatry and Behavioral Sciences at the University of Standford. “The more light exposure is received at inappropriate times, the weaker the circadian clock is. All these factors that influence the life cycle – for example, the immune system and energy – do not synchronize so well,” He continued. The question we must ask ourselves, according to these researchers, is what time policy helps to better adjust circadian rhythms. And the answer, at least for the US set, is that most people would support a lower circadian mismatch with the winter schedule. Does that mean that winter schedule is better? Actually, no. It is possible that it is the most complete study to date, but (As the researchers themselves recognize) There are many factors that researchers did not take into account and that, by itself, can reduce gain very substantively. But even giving the methodology good and accepting that citizens behave as researchers suppose, we would have to reproduce the analysis in Spain (or our reference countries) to know what the final result would be. After all, The countries that change the time are a minority And it makes sense to think that there are scenarios in which the time change could help reduce that circadian mismatch. One of the problems of countries as large as the US (or realities as diverse as EU) is that making joint decisions is difficult. And then? I’m afraid that we are a little better than before, but almost in the same place: we still have no remotely if it is good or bad, and that we attribute more and more things.

Alicante has found a tourist mine in an unexpected place that is contributing thousands of visits: Poland

by

Between Warsaw and Poland there are about 2,200 kilometers and above all a change of climate, landscapes and considerable architecture. Despite that difference (or precisely for her) both cities seem to have found a powerful link: tourism. I pointed it yesterday The avant -garde in a broad article On the boom of Polish tourism in the Valencian town and the last corroborate it AENA datawhich show that air traffic from and to Poland grows at a good pace, much more in fact of what general traffic has grown during this year. In the hotels and streets of Alicante more and more strongly sounds the Polish accent, which agrees with National data collected by Turespaña. How much has it increased? According to The latest data From Aena, during the first ten months of 2025 they moved between Poland and Alicante-Elche Miguel Hernández Airport 676,502 travelers, 20.6% more than in the same period of 2024. In August, one month with an intense flow of tourists, 94,000, 20% more than last year were touched. The data reflects all kinds of displacements, both arrivals and exits, which also includes residents of Alicante who travel to Poland, but gives an idea of ​​the interest raised by the Costa Blanca in the country. AENA graph with passenger traffic from Alicante-Elche Miguel Hdez airport. Why is it important? At the outset, because that growth is much higher than that of Aena’s network or the Alicante-Elche airport assembly, which during the same period saw how passenger flow increased 9.1%. Growing is easier when you start from low data, but the truth is that Poland has gone to play an interesting role in the Valencian terminal. Although its 676,500 users represent 5% of the global airfield traffic, Poland is already the fifth main destination of its grid by user volume. The room, if we focus exclusively on the international market, without Spain. Right now they only exceed Poland in the United Kingdom travelers (4.4 million), Holland (819,800) and Germany (813,200). They all grow, but so far this year, none has done it to the rhythm of the Polish market. Their data in fact exceed those of other destinations (and traditional tourist -emitting points) closer to the Peninsula, such as Belgium, France or Italy. While the transfer of airplanes increased between Alicante-Elche and those foreign countries, what descended was the flow with the airports of the rest of Spain (-2.3%), which fits with The stagnation which seems to cross domestic tourism. What is the reason? Tastes and affinities apart, there are two keys that help to understand the increase in trafficking traffic between Alicante and Poland and especially the foreseeable interest that the Valencian town arouses in the Central European country. The first is connectivity. Alicante airport has various routes With Poland operated by Ryanair and Wizz Airtwo companies specialized in the market Low Cost and an aggressive rate policy. The first offers flights with several Polish terminals. The second, with Gdańsk, city of the Baltic Coast. And the other reason? The promotion. Alicante has made a clear effort to make known in the Polish market. Last year the Tourism Patronage Alicante City & Beach took advantage An initiative of Turespaña and the Polish Touroper Nekera to present the destination before 160 Warsaw and Katowice agents. “Polish tourism has not stopped growing in recent years in the city”, He stood out The Councilor for Tourism. More recently it has been the Patronato Costa Blanca that It has moved token To “connect the tourist offer of the province of Alicante with the Polish travel market”, giving known in situ, in Poland itself, especially in the cities of Wroclaw, Poznan, Gdansk and Warsaw. Is it something new? Not quite. As I recognized The Alicante Tourism Councilor, the flow of travelers from Poland has grown until occupying an “important” place in the sector. And interest does not monopolize only Alicante. A decade ago Already the Ministry of Tourism advertised the benefits of the Valencian Community in Poland and Benidorm has also verified the great interest that arouses as destination both in that country and others of the East. And not only in the traditional holiday market. At least in 2023 The demand reached residential tourism. In general, Turespaña Calculate That in 2024 Spain visited 2.4 million Polish tourists, 2.6% of the total number of travelers who arrived in our country. “The very positive evolution of this market is remarkable. Compared to 2019 Poland has contributed more than one million additional tourists, which represents an increase of more than 43%,” stands out The organism. “From the point of view of the estimated total nominal expenditure, the evolution has been even better (48.8).” Here they seek mainly leisure and their favorite destinations are warm regions, such as Canary Islands (22%), Valencian Community (19%), Andalusia and Catalonia (18%).

The “lost continents” of our planet are leaving their trail in an unthinkable place: the earth’s magnetic field

by

Life as we know it depends largely on the stability of the Earth’s magnetic field. But this stability (or the absence of this) depends in turn on factors that we still do not understand. Some of these factors are in the outer space, others instead are thousands of kilometers hidden under our feet. From the bottom up. Huge geological structures located in the land mantle They could be contributing To destabilize the magnetic field that protects the land from radiation and particles from space. These are the “sunk continents”, the large provinces of low speed (LLVP). Sunk continents. This last name is due to the fact that these rock masses located in the deep layers of the land mantle stand out from the rest of its surroundings because the seismic waves move more slowly through them. Through this method we know the existence of two large LLVP, one located under the African tectonic plaque and the other located under the peaceful plaque. We do not know exactly what they are or what is the origin of these rock masses. A hypothesis indicates that could be remains of the impact between the primal earth and a second planet called Theia. The Moon would be one of the results of that impact, another would be that part of The remains of Theia would have been “embedded” on earth, specifically in the mantle, giving rise to these “lost continents.” However, other studies have pointed out that these masses would be formed, at least partially of ocean cortex buried through subductive geological processes, which would make them more close to “lost continents” of the surface of the earth. The new study can be linked to this last hypothesis. Fed by a “fire ring.” The team He modeled the movements Convectives of the land mantle, also creating a reconstruction of the possible movement of the tecton plates on the surface of the Earth in the last 1,000 million years. Thus they found indications that the African dough would contain older and more “mixed” than the peaceful mass, which would contain 50% more oceanic crust, a more “young” cortex and different from the surrounding mantle. This could be explained with the call “Pacific Fire Ring”, A vast network of failures, many of them subductive that little by little they engulf part of the earth’s crust. This “banquet” would have been producing for at least 300 million years and would be serving to feed the Pacific LLVP. The details of the study were published In an article In the magazine Scientific Reportsof Nature. In diversity is the key. Until now, intuition pointed out that these two underground “continents” had a similar composition. The reason is precisely that the two slow down the passage of seismic waves in a similar way, which leads us to the intuition of thinking that these are very similar in their characteristics. However, the team responsible for the new work indicates that this may not be the case. The reason is that the temperature is more than the material that makes these regions slow the waves that cross them. The balance is complicated. The formations are more or less opposite in the Terrestrial globe, which in principle is great news: since these masses influence the way in which the temperature of the earth’s core is spread in higher layers, which in turn affects the conductive movements inside the nucleus of the planet. Since these movements are those that allow the existence of a magnetic field On Earth, the way in which they occur has a lot of impact on this field. If the LLVPs are different, the way in which the field is generated ceases to be symmetrical as one would expect, which gives rise to the appearance of imbalances. Discussing the different hypotheses. As we pointed out at the beginning, the new study can be linked to the idea that the LLVPs are the result of the sinking of earth cortex pieces and not the remains of a planet of the original solar system. Although the study does not offer conclusive evidence confirming this first hypothesis, It can be seen as a new more test in this address.

China has just told the world the place it wants to occupy. And he has done it with a parade of weapons that seem like science fiction

by

During September 3, Beijing has become the stage of one of the Chinese military parades more elaborate that are remembered, commemorating the 80th anniversary of the end of World War II. An event that China has used to Promote nationalism through a parade where to show the world the place he wants to occupy. And according to the artillery that has seen the lightThere are no limits. Artillery as support. As we said, the imposing military parade in Beijing was conceived as An unequivocal message: Xi Jinping’s vision of a new world order with China in the center has a warlike vanguard apparatus that begins to be at the height, and even ahead, of its rivals. Among the protagonists highlighted the new intercontinental ballistic missile DF-61successor of DF-41together with missiles with hypersonic plankers capable of exceeding the speed of sound five times and complicating any antimile defense. The demonstration included a broad Drones repertoire (aerial, terrestrial and submarines) with functions ranging from direct combat to logistics, some designed to act as “faithful squires” of Chinese furtive fighters, consolidating the EPL’s commitment to the Autonomous War. DF-61 Directed energy weapons. Beyond the missiles, the true revolution was on the exhibition of Laser and energy weapons directed, in naval and land versions, capable of neutralizing sensory and drones enemy at ridiculous costs compared to conventional ammunition. If these systems are deployed in number, such as They hinted Official sources could suppose an unprecedented challenge for any force that tries to stop Chinese military movements in their region of influence. This technological turn, supported by an enormous industrial capacity, points to a strategy where the quantity and sophistication They combine to cement China’s strategic ascent. Set of laser weapons during the military parade Two versions. They appeared Two laser systems Air defense: a large one, intended for its installation in warships, and another mounted on an eight -wheeled vehicle, capable of hosting the necessary electrical power to overcome the limitations of previous versions. These systems, which do not depend on kinetic projectiles but on Electromagnetic energy To destroy objectives through heat, electrical interference or sensor blindness, they mark a turning point in the anti -aircraft and anti -anton defense. In front of them, high -power microwave systems (also in development) offer the ability to neutralize whole swarms of drones with simultaneous bursts. The logistics and economic advantage is evident: each shot costs a fraction of a missile and does not require transporting heavy ammunition, only energy. Submarine drone AJX002 The debut of underwater drones. China also showed for the first time Two submarine vehicles not large -sized (Xluuv), consolidating their leadership in a field where at least five different programs in the test phase already operate. One of the exhibited models, identified as AJX002measures between 18 and 20 meters long with a reduced diameter of up to 1.5 meters, while the second shares length but is considerably wider, between 2 and 3 meters, and carries two masts. Although their specific missions have not been revealed, analysts consider carry torpedoes or mineseither fulfill recognition functions in prolonged and high autonomy operations. With this presentation, the Chinese Navy confirms its intention to integrate underwater platforms Autonomous on a large scaleexpanding the unmanned war options in a domain traditionally reserved for conventional submarines. Some of the hypersonic missiles shown The YJ-17: hypersonic and “nuclear.” Among the most strategic revelations The YJ-17 wasa missile that combines the naval denomination of the YJ family with the technological inheritance of DF-17the first medium -range ballistic missile with a hypersonic planner (HGV) developed by China. If the DF-17 already demonstrated extreme precision in tests (capable of impacting a few meters from its target after performing evasive maneuvers), the YJ-17 supposes the adaptation of that system For vertical pitchers of warships. Although it is believed that it can carry conventional eyelets, its nuclear capacity cannot be ruled out, which reinforces its deterrent value. Non -manned wing aircraft of the Plaaf. Two different configurations were seen but no designation details have been provided The industrial muscle as an advantage. No doubt, the parade was also proof of the volume of production that China can sustain. According to analysts Like Malcolm Davisthe country demonstrates the ability to develop, manufacture and deploy faster and higher advanced systems than the West. In other words: it is a reminder that, while in World War II the American industry inclined the global balance, today is Beijing who You can manufacture in mass Military teams with efficiency that Washington can hardly match. The CSIS data They confirm this trend: Chinese military expenditure has multiplied by thirteen in 30 years and already exceeds its immediate neighbors, quintupllica that of Japan and septuming that of South Korea. Anti-Enlambre Training (MENGSHI Laser “OW5-A10”, “PLB-625” cannon of 6 x 25 mm, 30 mm cannon, “Mini dome CUAV FK-3000”, Laser HMV3 “OW5-A50”) The naval dimension. Already We count yesterday. The biggest difference with the United States is perceived in the sea: by 2030, the Chinese Navy could have a 48% more ships of war that the American, which revives the historical maxim that the largest fleet usually imposes itself. While in the West it is confident that technological superiority, such as drone swarms with artificial intelligence, maintain balance, the parade showed that China already has Advanced autonomous systems in active duty and in operational quantities. In addition, the introduction of laser defenses against drones and missiles reinforces Beijing’s narrative about an “intelligent war”, where autonomy and systems network dominate the battlefield. JY-17 The Arsenal per sea. The YJ-17 did not appear alone: ​​it was accompanied by anti-man- YJ-15, YJ-19 and YJ-20all conceived to be deployed from the largest surface fleet in the world, composed of destroyers and frigates with vertical pitchers. Here the strategic message seems clear: the American aircraft carriers, the cornerstone of Washington’s naval power in the Pacific, could be vulnerable at any point in the region before a coordinated rain Hypersonic missiles and cruise released from multiple platforms.

The place where dozens of animal cells are stored in case there is a great disaster

by

In a basement from the Biomedical Research Park in Barcelona, ​​between liquid nitrogen clouds, an incalculable value treasure is saved: an ark of Noah of the 21st century. It does not contain couples of animals, but thousands of small tubes at -196 ° C that retain life. It is the Cryozooa pioneer biobanco that stores cell lines of hundreds of species, many of them to the edge of extinction. It is not an achievement, but a warning. At the head of this initiative is the renowned molecular biologist Tomàs Marquès-Bonet, one of the Greater world experts in genomics of great worlds. As the world has collected, This project is not a great achievementbut a last use resource in the event that the main species of our planet are extinguished. This is explained by the researcher himself: Recovering species with these techniques is the failure of society, but it is amazing to be able to do it. The first must be to preserve in your habitat the animals that remain alive. And when everything else has failed, it is better to have these banks than not to have them, like an ace in the manga Of a biopsy to cell immortality. The concept, inspired by the famous San Diego Frozen Zoo, is as elegant as powerful. The Cryozoo team collaborates with about twenty European zoos and aquariums to obtain small tissue samples, often during routine veterinary reviews. In this way, with a millimeter of leather you can create a stock of cell lines and keep them forever. The process is surprisingly pragmatic. Zoos send biopsies in tubes with a conservation medium. A complex cold chain is not always needed; Sometimes, as in the case of a stranded whale in Valencia, a little serum is enough to start. In the laboratory conservation is consumed. Once the fabric reaches the laboratory, Technicians cultivate cellsallowing them to divide and multiply to form a homogeneous population that is called ‘cell line’. Reprogramming to stem cells. The most revolutionary step is reprogramming. They can take a skin cell and, by laboratory techniques, return it to a pluripotent state, turning it into a stem cell of induced pluripotentiality (IPSC). “A stem cell is a pluripotent cell, which means that it can become what you want,” says Marquès-Bonet. And once this is achieved, the last step of cryopreservation of both cell lines and IPSC in liquid nitrogen is reached, where they can remain viable for decades, waiting for the science of the future to need them. A technique similar to that used for human embryo conservationfor example, in fertility processes. Currently, Cryozoo already houses more than 2,000 samples of almost 300 species, which have generated 350 high quality cell lines. Among its “treasures” are Montseny Triton cells (the most threatened amphibian in Europe), the Pyrenean frog, the ORYX DAMMAH (A species already extinct in nature) and even the rhinoceros Pedro, the longest in Europe, deceased in 2023. Quality on quantity. What distinguishes Cryozoo from other initiatives is not its size, but its obsession with quality. And it is that the bank’s goal is not to have the more cell lines the better, but to have the best and most viable. To achieve this, they have implemented a step that they consider crucial and that makes them unique: sequence the complete genome of each cell line they create. In this way, they ensure that the genome of the cultivated cell is a faithful representation to the original animal without genetic aberrations that have occurred in the laboratory. AND the fact of sequencing it It is also a great advance for science, because on many occasions it is the first time that this technique is done in a specific species. Something that will be in a repository that any researcher can consult. They want to avoid using these cells. With the ability to convert skin cells into ovules and sperm, the question is inevitable: is the ultimate goal of ‘de -sextinction’? But researchers have it clear: it is a red line that they never want to pass. Although technology has already allowed to bring functionally extinct species such as the Huron of black legs or the Przewalski horse, the Cryozoo team considers that its function is to be custodians of the genetic material, not to execute reproduction. They would only make their cells available to a project of this caliber if it had the validation of the International Union for Nature Conservation (IUCN) and a global consensus. Cloning is not the step. Although it can be attractive to make ‘photocopies’ of animals in a laboratory, the reality is that today It is a expensive and inefficient process. The real effort of the researchers today lies in preserving ecosystems so that animals live in them and reproduce naturally. Without man having to intervene. A cell bank to save animals … and also humans. The value of Cryozoo does not only reside in that distant possibility of resuscitating species. Its applications are immediate and revolutionary for current research. And it is that diseases can be studied without damaging any living being by infecting cells with a pathogen to see how cells react. But it goes further, being able to create ‘mini organs’ to investigate the biology of some species, test drugs safely or investigate human diseases in the genetics of these animals. A hope for an uncertain future. The changes that succumb to our planet can cause in the future to be a real climatic emergency. That is why we prepare the ‘end of the end of the world‘To collect all the seeds of the world, and now we also collect all animals. A genetic library that, in the best stage, we will only consult for pure scientific curiosity and never for a planetary emergency.

The AI ​​is obsessed with which we are talking to her. He has a golden opportunity in an unsuspected place: our lounge

by

Microsoft has sneaked into Samsung’s teles. This has been announced by both companies, which have reached an agreement so that Copilot is part both of the future Smart TVS and the company’s monitors. It is an interesting announcement not so much for what it means for these two companies, but for the tendency to which it points. Why is it important. Here Microsoft achieves a small triumph for its artificial intelligence solutions, and does so by the hand of a giant like Samsung. But here what attracts attention is that First great integration of AI in products that until now did not want to know much about it. Talk without stopping with TV. Our televisions are perfect candidates for adapted systems specifically to them, and this is a striking step in that direction. The command continues and will continue to be better in many cases (button to rise volume instead of “rises the volume a bit”, for example), no doubt. However, The Chromecast or the Fire TV Stick They already showed us that saying “reproduces the trailer of ‘Superman’” or “reproduces ‘Stranger Things’ in Netflix” is also a very powerful option. An AI to go further. Those functions of the traditional voice attendees of the teles are interesting, but having a model of AI as a co -pilot will allow that experience beyond and Interact with TV in a more versatile way. You can ask for time and visual information will appear accompanying audio information, for example, or by a movie and a card with its IMDB or Rotten Tomatoes qualification will also appear. Where did I stay with this series yesterday? And of course, we can ask us to recommend a movie – “What mystery film must be fun?” – Or that gives us related information about it – “What more movies has made the director of this film? We can talk with Copilot Normally on any subject, because after all, it is a generative AI and are designed for that purpose. The speakers, the next border. There is another hardware element that awaits the arrival of AI as a May water: smart speakers. That intelligent have never had much: Satya Nadella, CEO of Microsoft, already said years ago that these devices “They were more silly than a stone“. The option of being able to talk to these products when they are enhanced by a generative model such as Chatgpt or its rivals is very promising, and the curious thing is that at this point we should already have a great protagonist in this field. What vadis, Alexa+? Amazon is undoubtedly the great absentee of the AI ​​segment, and for months now Alexa+ presentedits new platform with generative AI models that in theory Ibn to flood your family of Amazon Echo devices. The deployment, however, is being infuriatingand the project still has a very limited reach, we assume that because they prefer to go on safe. The privacy dilemma. It is inevitable to think that one of the possible risks that will involve the use of these devices with this technology will be the invasion of our privacy. We already know How do TVS manufacturers spend them With its users in this section, and the traditional smart speakers have already built many suspicions about it In the past. In addition, where is the limit between a useful and an annoying or invasive presence in the living room? The battle to conquer your lounge started has. It seems inevitable that AI ends up being an integral part of our televisions as it begins to be in our computers or mobiles. Smart speakers are specially prepared so that in the future we talk more than ever with them, but will there be other hardware solutions that go further? Domestic robots, maybe? There is in this segment a huge challenge in many sections – non -invasive experience and, as far as possible, private – but also an extraordinary opportunity. And Microsoft, for the moment, has seen it. Image | Jens Kreuter In Xataka | There is a new fever among ultra -ups: fed up with technology, they want houses as “dumb” as possible

feed solar and wind energy the darkest and colder place in the world

by

In a place where the nights last six months, wind gusts can reach 300 km/hy them the temperatures collapse below the −40 ° C, the idea of using solar and wind energy sounds like a joke. For a few months, however, China is feeding its Antarctica base with renewable energy. How the hell have they done it? Short. Five years ago, electrical engineer Sun Hongbin, today president of the Technological University of Taiyuan, received what seemed an impossible mission: to build a renewable energy system capable of supporting the most extreme conditions of the earth. As he has told Scientific AmericanThe objective was to align the new Qinling Antarctic Station with the green commitments of the Chinese government. The result cost 14 million dollars, was officially inaugurated in early 2025 and is a technological feat that now other countries with Antarctica bases want to imitate. Diesel logistics nightmare. Antarctica stations work almost exclusively with diesel generators, but this dependency has a very high cost. Not only because diesel is expensive, but because transporting it is a logistics nightmare that requires mobilizing breakwinds and military personnel for each replenishment trip, which is usually annual. In addition, environmental risk is huge. The spills are frequent and, in such a fragile ecosystem, where the low temperatures slow down the decomposition, any discharge is a catastrophe. Not to mention the emissions of the combustion itself. The renewables did not endure. The problem of conventional renewable systems is that they do not work in Antarctica. The extreme cold causes the blades of the wind turbines to become brittle, the performance of the solar panels plummeted and the lithium batteries stop working. And that without counting the polar night: six months without seeing the sunlight. Provided to overcome these obstacles, Sun Hongbin did not walk with little ones. His team raised A 2,000 square meters laboratory At the Technological University of Taiyuan that, basically, it was a piece of Antarctica in China. To put to the limit each component, they simulated freezing temperatures, winds of more than 200 km/hyams artificial. How the hell did it. After four years of tests, the team found a robust system that combines wind energy, solar energy, batteries and, the key of everything, hydrogen. The wind turbines have a vertical design reminiscent of an egg blender, which reduces the structural tension and lowers the center of gravity so that the wind does not take them. The solar panels are mounted on a special frame made of reinforced plastic with carbon fiber. This material has a lower thermal conductivity than aluminum, so it does not deform so easily with sudden temperature changes. As for the batteries, instead of the typical lithium ions, they used lithium-ditana. Its internal chemistry facilitates the movement of ions at temperatures below zero. In addition, they put them in a thermal housing that takes advantage of their own residual heat to stay at an optimal temperature. The cake widge. During the polar summer, when there is a sun and spare wind, energy is used to feed an electrolyzer that separates water into oxygen and hydrogen. Hydrogen is stored in high pressure tanks. When winter arrives and the other sources falter, hydrogen is recombine with oxygen in a fuel pile to generate electricity. The only residue? Water and heat, which are recycled to heat the system itself. According to those responsible for the project, the base can work for about 48 hours only with the energy stored in the form of hydrogen. The way to follow. The integrated wind, sun, hydrogen and batteries system has a total capacity of about 230 kW, which It is 60% of the capacity Total Qinling generation. The remaining 40% continues to depend on diesel as support, but the savings is gigantic, so it has received praise from the international scientific community. This is the “first large -scale clean energy system in the world capable of working all year in a polar environment.” And there are already other countries investigating how to adopt it while China maintains its goal of reaching 100% renewable energy.

With GPT-5, Openai wants to place it at the center of all things

by

Microsoft and Apple defined the PC segment and They made him a Commodity. The computer became in something standardcommon and easily interchangeable, Without too much differentiation. Those who ended up winning that battle, however, were Microsoft and Intel, who took a good part of the benefits. Then the mobile would arrive. It is clear that those who have won this segment have been Apple (with iOS) and Google (with Android), but be careful, because those who defined it were two companies. The first, the aforementioned Apple, which also triumphed with the APP Store paradigm And it has ended up taking about half of the income. The second, a company where perhaps not many would have thought: Amazon. The electronic commerce giant would end up promoting the cloud with its Amazon Web Services, and It also ended up turning that cloud into another Commodity. And as happened with Microsoft and the PC or Apple and the mobile, Amazon ended up monopolizing a good part of the benefits of the cloud. A cloud we considerably access (for example, through the iPhone), but to which we don’t even pay too much attention: It is there and works, as before the PC and now the mobile. As explained by analyst Ben Thompson In StratecheryThey are everything Commodities. Well, there are those who expect AI to end up becoming another Commodity. That this segment for which now They compete a multitude of companies It ends up becoming (perhaps) a duopoly like the one created by Microsoft and Intel in the PC or Apple and Google on the mobile. Foundational models are the new PC/mobile, and although there are strong candidates to end up winning that race, everything is yet to be defined. AI like Commodity And that is where GPT-5 comes into play, which wants to be something like Apple’s App Store or Amazon AWS: that platform that Turn it in the company that defines the AI race and manages to win it. And that over time also influence that conversion of AI in a Commodity. With this OpenAi launch you play a lot. Sam Altman has been living in two things for years. On the one hand, of the success of Chatgpt, a remarkable product, but for the moment not revolutionary. On the other, Above all, of Hype. Of promises and moments wow like the one they gave us With GPT-4O or with them Studio Ghibli Style Images. Because we insist, Chatgpt is a good product that has proven useful as an assistant in all types of tasks, but especially in programming. Has unusual an unusual fever for the generative AI and data centersand has caused many companies to trust their future –or rather they bet– To this technology. But revolutions, for the moment, few. Comparisons with phenomena such as PC, Internet or mobile are inevitable. And in all of them discourse and evolution were similar. There were doubts and skepticism at the beginning, exaggerated bets later –Hi, bubble Puntocom– And, indeed, revolution. And it is expected that something like this passes with the pass, although in fact the most devout of this technology claim that this will go further. Others, much more skeptical, believe that This is a bubble that will end exploding … although it can end it deriving the true revolutionas happened with the Internet. Whether there is bubble and explodes as if not, GPT-5 is for Openai a key model for your future. And the paradox of this model is that the company needs the greatest jump in the history of AI Just when it seems most impossible. It is about to see how good the model is really, but the company cannot suffer Another fiasco like GPT-4.5 or your reputation will be very damaged. Will Openai achieve with GPT-5 and the AI what Microsoft, Apple or Amazon already achieved in their respective segments? That is the big question. And we will have to wait a bit to answer it.

It is not that Russia does not find the F-16 of Ukraine, is that kyiv has discovered the perfect hiding place for the future of wars

The problem of modern wars is that they have ceased to be A geographical matterand the current technological abilities, with the drones and the AI in the lead, are eroding the physical barriers that previously existed. That was clear, for example, with The Spiderweb operation of Ukraine on the Russian air bases. In fact, in the first 18 months of the war, Ukraine lost Very few planes On land in front of the Moscow number, and the last movement predicts an even lower figure. The mobility war. The Arrival of the F-16 To the Ukrainian Air Force has been accompanied by a parallel effort to create a mobile ecosystem capable of sustaining continuous operations in a scenario where each base is a potential white of aviation and Russian missiles. Solution? The Ukrainian Foundation Eat Back Alivein cooperation with the state conglomerate Office 61 and with the financial support of the UKRNAfta energy company, recently delivered a set of vehicles specifically designed to provide the F-16 of the necessary logistics flexibility. Four wheels and fighters. The acquisition It included workshop trucks for armament preparation, crane trucks for missile and pump load, pickups for personnel transport and, above all, a missions planning complex on wheels composed of A 6×6 truck and a habitable towing module, which will allow briefings, plan operations and move quickly where it is required. With this investment, encrypted in just over 1.2 million dollarsUkraine obtains not only a technical improvement (for example, reducing from a dozen to three the number of operators necessary to assemble ammunition in each plane), but also a Operational advantage in an environment where speed and dispersion are survival synonyms. The concept of distributed operations. The logic behind this innovation is simple but strategic: prevent Russia from being able to anticipate or destroy on land Western manufacturing fighters. Ukraine had already developed the custom of Alternate air bases and even use highways as impromptu tracks, an inherited practice of the Soviet design to operate in austere environments, but now amplified by the high -tech character of the F-16. This ability to Move with infrastructure Wheel support converts each road into a potential base and each mission into a concealment game. In this sense, new vehicles are not simple trucks: they represent an adaptive doctrine in which aviation abandons the notion of fixed bases and embraces total mobility as a shield against missile attacks, drones and enemy bombers. NATO and American learning. The lessons that Ukraine applies in extreme conditions are being observed carefully by the United States and its allies. It We count The other day: the doctrine of AGILE COMBAT EMPLOYMENT (ACE), which seeks to disperse combat aviation in multiple locations Temporary, is nourished directly from the Ukrainian experience. USAF generals They recognize that Ukraine has managed to avoid the mass destruction of his aviation thanks to not taking off or landing in the same place twice in a row, forcing the enemy to waste intelligence and ammunition. The counterpart of this agility is Logistics demand: Each site needs fuel, ammunition and maintenance equipment that must be compact, transportable and fast to install. The United States Marines itself has started projects To provide air-terrifying trucks on C-130s and lighter and more modular equipment that can accompany squadrons in constant movements, which marks a deep turn in the conception of the air war. Aviation future. What’s doubt, what is today Test in Ukraine It has global implications. In a eventual confrontation with China in the Pacificno power could guarantee the protection of all its air bases, and mobile dispersion will be the key to survival. The fighters will not be able to remain in the same airfield without dense anti -aircraft defense; Their operations will be measured in hours or days, with specific deployments for refueling and rearming before returning to main main bases. This will require redesign support equipment lighterto think about new sustaining architectures and maximize land and aerial mobility. Ukraine, again laboratory. In short, the incorporation of these Ten vehicles At the service of the F-16 it may seem a lower detail in the heat of the war, but embodies a deeper transformation: that of an aviation that can no longer rely on the solidity of its bases and that depends on speed, dispersion and Logistics creativity. Ukraine thus becomes Test field of a doctrine that west, and in particular the United States, contemplates as essential to survive the high intensity conflicts of the future. Thus, each workshop truck and each rolling planning module are not only metal pieces, but symbols of how war forces to reinvent the way of conceiving today’s aerial power.

It is called 815a and its power lies in the place from which you can watch

That China is determined to intensify its operations Navales is out of any doubt. Not only is it raising a fleet of aircraft carrier that you have never had, its operations with Combined exercises in nearby waters (And not so much) They attest to that explicit demonstration of their global ambition. Now, in addition, you have to add the last demonstration of Beijing force: a gigantic detective. The new era of naval espionage. Yes, spy ships Type 815a They have become a fundamental piece of Chinese maritime strategy. His recurring presence in disputed waters and in international exercises reflects Beijing’s determination to project power and collect strategic intelligence persistently. In fact, the recent case of tianwangxingintercepted by the Philippines coast guard within the exclusive economic zone of Manila while escorting a destroyer and a Chinese coast guard, symbolizes this new stage of aggressive surveillance. And more. The remarkable thing is that the operation coincided with the Aerreo Exercise Cope Thunderin which the United States first deployed F-35 furtive fighters In the Philippines, which reveals how the Chinese Navy guides its naval espionage to capture in real time the military capabilities of Washington and its allies in the Pacific. Expanding float. The origin of 815a dates back to late ninetiesWhen China sought technological independence in naval intelligence. The first ship, Beijixingwas the first totally designed and built in the country, opening a series that since 2010 has multiplied with the arrival of more advanced variants. With dimensions of 130 meters of length and 6,000 tons of displacement, these boats count With diesel engines of great autonomy capable of sustaining prolonged missions thousands of kilometers from its bases. By incorporating furtive techniques into the helmet, closed masts and absorbent coatings, they manage to reduce their radar firm. The Type 815a One More Thing. However, the distinctive feature of the class are its bulky radomes, which protect electronic intelligence systems (ELINT), of communications (Comint) and radars capable of capturing and analyzing signals in wide ranges of the electromagnetic spectrum. Detection capabilities. What really makes these ships A complete map of the adversary military environment. As? They can identify radar emissions of aircrafts and destroyers to more than 700 kilometersand even to 1,200 according to some reports, in addition to tracking 1,500 kilometers. The information collected is transmitted in real time through connected redundant satellite links to the Beidou systemallowing immediate integration with anti -men’s ballistic missiles like DF-26 or the Hypersonic YJ-21. In this way, the presence of a single 815a in the vicinity of a multinational naval exercise is equivalent to placing a whole fleet under the sight of Chinese attack systems. From sea to space. Plus: The new recognition ship Liaowang-1 He has taken this doctrine even further. Its sensors, with detection capacity of up to 6,000 kilometers and satellite monitoring in geostationary orbit, expand the Chinese surveillance field to space. With six poachers endowed with multiband sensors, neural networks algorithms to classify targets with 95% precision Even under electromagnetic interference, and Aesa radar modules based on gallium nitride (ten times more powerful than previous generations), the Liaowang-1 constitutes a jump that S sItúa China at advantage against US equivalents such as Howard O. Lorenzen. This not only strengthens Chinese naval deterrence, but opens a spectrum of early control and warning operations that transcends the maritime surface. Surveillance strategy. The constant practice of sending An 815a to monitor international maneuvers (from RIMPAC In Hawaii Even Talisman Sabre In Australia) it has become a routine tactic. The mere entry of one of these ships in the area of an exercise Activate the network Chinese satellite, which transforms a routine deployment into a real -time attack simulation. For United States allies, this presence means having to Limit radar emissions and communications, which reduces the effectiveness of joint maneuvers. In other words: in an open conflict scenario, the shadow of an 815a would imply that the position of each enemy ship would already be incorporated in the Chinese missile guidance calculations. Strategic implications. Beyond electronic war and classic naval espionage, 815a constitutes A central node in the concept of Chinese multidominium warcapable of linking the surface of the sea, airspace and terrestrial orbit. Its visibility, however, also represents a weakness, since its radomes make it an easily identifiable target. Analysts expect future variants incorporate antennas Conformal integrated into the helmet, increasing its stealth and reducing vulnerabilities. The inclusion of command systems based on artificial intelligence is also anticipated to coordinate swarms of drones and electronic attacks autonomously, expanding the radius of action of Chinese intelligence beyond physical. Silent threat. In short, the 815a shipswith its low profile in terms of weapons and its enormous reach in matters of intelligence, they embody the new paradigm of the Naval War: it is not the visible fire power that defines superiority, but the ability to collectprocess and exploit data in real time to guide long -range weapons. China has turned these platforms into strategic multipliers that guarantee that any American attack group in the Indo-Pacific is under constant observation and, potentially, under direct threat of its missile arsenal. In them, Beijing’s transition is condensed from being a regional vigilant power to Aspiring superpower With the ability to control the sea, air and outer space.
