“In inheritances it is a mistake not to ask for the deceased’s life insurance certificates”

by

When a family member dies, the pain of loss is joined by an avalanche of legal and administrative procedures that must be fulfilled in a certain order. Therefore, between the mourning and the paperwork, there is a document that runs a serious risk of not being processed: the application for life insurance certificates. This certificate indicates whether the deceased had contracted any type of life insurance. This, which at first glance may seem obvious, can be a procedure that involves the loss of thousands of euros. for the heirs for not claiming compensation from the insurers. The failure that, surprisingly, is very common. As Manuel Hernández García, lawyer and director of Vilches Abogados, said, in a video from his YouTube channel, not requesting this life insurance certificate is one of the most common mistakes in inheritances. “On many occasions, families do not request life insurance certificates,” recalls the lawyer. The curious fact is that “insurance companies have an obligation to transmit this information about the deceased’s life insurance to state agencies.” That is, insurers are obliged to communicate in which insurance policies a specific person appears as a beneficiary, but they are not obliged to notify the heirs directly. A simple procedure but not for the impatient. The file in which all life insurance beneficiaries are collected is called the Registry of Death Coverage Insurance Contracts. It was created by Law 20/2005 and today it is managed by the Ministry of Justice. Anyone interested can request the insurance certificate and it includes the name and surname and what policies the deceased had in force. However, and this is one of the reasons why this certificate is often left behind in the inheritance process, it cannot be requested until after fifteen business days since death. Any attempt to apply earlier will result in your automatic denial. The procedure is done through the form 790 and can be processed online, by mail or in person, with the death certificate at hand. The registry responds within a maximum of seven business days. Some death insurance policies include administrative coverage in which they are responsible for requesting this certificate. Five years, not one more. We come to one of the most delicate parts of the process since insurance companies are obliged to indicate in that certificate what insurance each deceased has, but not to notify the heirs who are beneficiaries of it. As indicated by the insurer Aegonhe article 23 of the Insurance Contract Law establishes that heirs have a maximum period of five years from death to claim life insurance. After that time, the money simply remains in the hands of the insurer. Sure, how sure? The key is that much of that “forgotten” money does not come from life insurance policies themselves, but from “invisible” policies included in third-party services. Credit cards, banking and financial loan services, home insurance, vehicle insurance, which in addition to offering the main coverage, also allocate part of the coverage to insuring the service provider. According to the last Social Insurance Report, In Spain, 22 million people have taken out risk life insurance and many people are unaware that they have this coverage. Notaries as a last resort. The Registry creation life insurance also imposed an additional obligation for notaries, who must include the certificate from the Insurance Registry of the deceased before the award of the inheritance and must warn the heirs if there is any policy that covers said death so that it is recorded.

Christopher Nolan explains why he filmed ‘The Odyssey’ in IMAX

by

Christopher Nolan has not chosen the 65mm IMAX format for ‘The Odyssey’ as a simple technical boast. In reality, for this director it is a narrative tool at the service of a mythological scale story. Homer’s poem tells of endless sea voyages, storms, monsters and a journey that tests the limits of human endurance. Nolan wanted the viewer feel that immensity in a physical waynot just intellectual. And the only way to achieve this, as the director himself explained, was to completely fill the visual field of the movie theater. This ambition explains why, unlike previous works such as ‘Batman: The Dark Knight’, ‘Interstellar’ or ‘Oppenheimer’where IMAX is reserved for certain sequences of great impact, in ‘The Odyssey’ this format is maintained throughout the entire footage. Nolan has thus broken his own habit of alternating formats according to the intensity of each scene. The Homeric epic demands that the feeling of grandeur never wane, not even in the most intimate passages of the plot. IMAX’s 1.43:1 aspect ratio, much more vertical than the usual widescreen image in commercial cinema, is the key to this decision. By filling the viewer’s peripheral vision, this format generates a sense of depth similar to 3D without the need for glasses, something Nolan considers essential to convey the magnitude of the landscapes and battles. The director has summed up his philosophy with a forceful phrase: it sought to offer the public “something new and exciting”, an experience that no other format could give with the same intensity. IMAX demands as much as it promises The heart of this creative ambition is an exceptional negative. The IMAX film format, technically known as 15/70, uses 15 perforations per frame compared to the usual four for 35mm, which increases the size of the negative tenfold. The result is a horizontal resolution that is around 18,000 theoretical pixels, compared to the 1,920 pixel width of a high definition home screen (which together with its 1,080 vertical lines makes up the Full HD standard), and a sharpness that Nolan considers unsurpassable even compared to productions shot directly in digital. Filming with this technology for an entire feature film has required developing new equipment. IMAX cameras are traditionally very noisy for filming dialoguesso the team created a silencer they call blimp (we can translate it as soundproof casing). The resulting camera, named ‘The Keighley’ after veteran IMAX executives Patricia and David Keighley, weighs about 300 pounds packed into its soundproof casing. Nolan maintains that the resulting image retains a quality superior to that of any digital production. In addition, the physical support adds another layer of demand. The celluloid tape had to be recharged every two and a half to three minutes, and a mirror system had to be installed so that the actors could see each other around this bulky device during filming. This celluloid also advances horizontally through the projector using a technique called rolling loopand a single 45-minute roll can weigh 140 kilos and exceed 4,600 meters in length. Nolan maintains that, even when this negative is scanned to digitize it and adapt it to rooms with laser projectors, the resulting image retains superior quality to that of any production born in digital. This conviction explains his insistence on defending celluloid against the advance of digital tools, a position that he has maintained consistently throughout his entire career. All this technical demand has a very high cost during the exhibition process: only about 40 theaters around the world can project IMAX in its full combination of 70 mm and giant screen, and finding trained personnel to handle these prints is increasingly difficult in an industry focused on digital for almost two decades. Spain, despite having several digital IMAX theaters and with projection in traditional 70 mm, it does not have any that combines both technologies, so the Spanish public will have to settle for digital versions that crop the image to a more panoramic aspect ratio, losing some of the visual information that Nolan captured at the top and bottom margins of the frame.

The Norwegian colony that has taken over a town in Alicante and even has its own constitution: L’Alfas del Pi

by

Avenida del Albir smells of saltpeter and marinated herring. There is brunost in the supermarket, that curious brown Norwegian cheese. There are also bags of salmiakki, the Finnish salty liquorice. A blond man walks with a bunad accompanied by two others in T-shirts. The three of them are sweating buckets. Even a dental clinic has its sign in Swedish, but it is not a residential neighborhood in Oslo or Stockholm, it is L’Alfàs del Pi. It is an Alicante enclave of 20,000 inhabitants that operates as a Viking base, the twelfth Norwegian county, under the harsh sun of the Mediterranean. A demographic delirium. The National Statistics Institute marks little more than 21,000 inhabitantsbut almost 30% of the census comes from Norway. Let’s add another 20% between Finns, Swedes and Danes. Official figures fluctuate depending on the season: many residents do not register their municipal register for tax reasons (there are only about 2,5000 registered Norwegians). However, visual reality does not lie. There are runes and several shop windows of local real estate agencies that ignore the euro and value villas directly in crowns. On the Costa Blanca. And here May 17 is celebrated with devotion. Because this day is celebrated as Norwegian Constitution Day. The party paralyzes the town and thousands of people parade through the central streets. Blonde children wave their flags and marching bands play the national anthem. The Spanish mayor, Vicente Arques Cortés, politician and educational psychologist, delivers institutional speeches in perfect Norwegian. Without them, “there would only be olive trees, almond trees and goats,” resume in which is, along with London, the largest colony of Nordic subjects on the planet. A diplomatic link of eight centuries. Already in the 13th century, King Haakon Haakonsson ‘the Elder’ traveled to Spain to marry his daughter to Philip, infant of Castile, fifth son of Ferdinand III and brother of King Alfonso X the Wise. According to the story, in the end the princess fell prey to melancholy for living so far from her birth home. His remains lie in the Collegiate Church of San Cosme and San Damián de Covarrubias, which gives rise to the pilgrimage route of San Olav. That marriage sealed one of the first great diplomatic ties between the Scandinavian kingdoms and the Iberian Peninsula. Princess Christina of Norway never adapted to the climate, the language or a Castilian court radically different from the fjords where she had grown up. He died just four years after arriving in Castilla, at only 28 years old. Their pain sealed a relationship that there will be those who consider began with the retirees of the Costa Blanca. Mafias and violence. In return, the event pages of L’Alfàs del Pi have a separate space. Because, apparently, they don’t just import peaceful retirees, they also attract outright terror. In this small Scandinavia, the Swedish and Norwegian mafia clans control a good part of the European drug trafficking from here. It has been known for a decade that clubs like Den Norske Klubb They are “problematic”. The bikers of Hells Angels They established operational bases in Alicante years ago and control a good part of the nightlife. Million-dollar money laundering schemes are still being investigated. To the recent news of sale of vapers for minors or the 17 people arrested by a criminal gang that stole jewelry at gunpoint is added to all that hashish that arrives in speedboats from Morocco, or the cocaine that enters through the ports of Valencia and Algeciras. Scandinavian organizations buy merchandise on Alicante soil. They then send it to northern Europe through complex logistics networks. Live and die without speaking Spanish. He Europol Report (SOCTA – Serious and Organized Crime Threat Assessment analyzes the expansion of Scandinavian criminal networks in southern Europe and concludes that “drastic measures” are required. Organized crime brings fresh blood and settling of scores. And the Home Office has published several crime balances of the UDYCO (Drugs and Organized Crime Unit) on this social problem. The Norwegian Costa Blanca Club, the Norwegian school, the monumental Protestant church and other services have been established so that the Norwegian resident can live comfortably without needing to pronounce a single word of Spanish, as happens in Fuengirola with the FinnsTorrevieja with its concentration of Russians and Ukrainians u Orihuela with the thousands of british that houses An oasis for good and bad. The vast majority of Norwegian residents are part of a community that has been settled for decades. Movies like ‘Luger‘ (2025) flirt with an idea that too often is just pure xenophobia. They have cultural associations such as the Volunteer Center-Frivilling, schools funded by Norway, sports clubs, press in their language, specialized shops and social life that has disrupted the local economy. The heat, and not only that of the sun but that of coexistence, explains why the municipality continues to be a reference for Scandinavian emigration in the Mediterranean. However, the municipality is also a victim of that other side. Local agents, for example, collaborate daily with Kripos, the Norwegian national police, which has already uncovered cases such as the network that operated paying with monero tokens. The Nordic noir, not as cold, but just as calculated in the palm-lined streets of L’Alfàs del Pi. Over the past few years, police helicopters have mapped the thermal signatures of the crypto mining farmsused to finance crime. How are you happening now to Belgiumthe Alicante networks served for the heyday of EncroChat (2020) and Sky ECC (2021), two networks from which European mafias moved with more than 800 criminals involved.

Spain has won the World Cup. Good luck finding the exact video of that moment you want to see again.

by

Spain is world champion again. And one of the questions that struck me this morning was how complicated it is, paradoxically, to find specific moments from this 2026 World Cup as opposed to how easy it is to locate those from the 2010 World Cup. It is a question that has nothing to do with the scoreboard but with how the Internet has evolved. In 16 years… will it be as easy to find the moments of 2026 as it is now to find those of 2010? The panoramic. In 2010, YouTube was the home of online video. Any recording of the South Africa final, made with TV or mobile cameras, ended up uploaded there, indexed on a platform designed to locate specific videos, with title and date. In 2026 that exercise is more difficult, and that difficulty is going to get worse. The video no longer lives in one place, now it also lives on TikTok, on Instagram, in private accounts, in stories that disappear after 24 hours, in whatsapp groups that never reach the search engine. Why is it important. We assume that we record and share more than ever, so we assume that everything is archived somewhere. It’s not like that. A fan records the goal from the stands with his cell phone, uploads it to TikTokgoes viral, a TV cuts it out for its news citing the source… and there the trail ends. That video may never make it to YouTube. The account that uploaded it may be private. It may not be easy to locate later using the TikTok search engine. And there may never be a record of that shot anywhere else. Between the lines. All platforms have become video platforms, but each one has a different purpose and editorial line, and that makes finding something specific a more complex task. Or impossible. It is a phenomenon similar to what has happened with text search, although for different reasons: content and communities have been divided into fragments that do not communicate with each other. The rise of newsletterscommunities locked in Discord or Telegram, etc. A centralized search engine indexes text designed to be found. An ephemeral video app indexes immediate attention, but not long-term memory. They are opposite design goals. Yes, but. For the occasional user it is much more difficult to locate moments in this atomization. For the user hooked on specific platforms, it is not so much because they know how to navigate them and know where to look within each one. That means that the problem is not only technological, but also one of skill and time invested in learning the logic of each application. And now what. In 16 years, someone will want to see moments from this World Cup, like the anthem played by tubas, or Ferran’s goal recorded from a very specific seat. If that video never reaches a platform with an archiving vocation, that person will find an empty space. The collective memory of that World Cup will largely depend on editorial decisions that none of the platforms involved took with the archive in mind, but rather with the minute in which that video retained attention.

An ancient necropolis in England has revealed what was Rome’s great weapon in Britain. And it has little to do with his army

by

The Roman Empire was forged with swords, strategy and hordes of legionaries, but the eternal city had an even more effective resource than its military power: its magnetism. Sometimes, before the soldiers, what reached the future conquered territories was the commercial influence of Rome. The clearest example has just been offered to us by Essex, United Kingdom, where archaeologists They have found a necropolis with several copper vessels, amphorae, nails, brooches and even a delicate molded glass bowl, an exclusive piece. The important thing, however, is not so much the ‘what’ as the ‘when’. Experts believe that those pieces that tell us about a connection with Rome are prior to the invasion of Britain in 43 AD, so they reveal a previous cultural, diplomatic and economic contact between both worlds. What has happened? What archaeologists have discovered an ancient necropolis south of the United Kingdom which confirms that, before the Roman invasion of 43 AD launched by Emperor Claudius, the region was already permeable to the influence that came from the other side of the English Channel. It is a key detail because it tells us both about the Iron Age in modern-day England and about Rome’s ability to extend its cultural influence beyond its military power. What have they found? A cemetery near Chelmsford, Essex. When excavating the area, researchers from UCL Institute of Archeology They located the cremated remains of more than a hundred individuals buried there about 2,000 years ago. To be more precise, the tombs appeared in an area surrounded by a ditch and, according to expertsdates for the most part from the 1st AD, so it “marks the transition towards Roman domination in Great Britain.” Why is it important? As they delved deeper, the archaeologists saw two clearly differentiated types of graves: there were the most common ones, which numbered in dozens and basically consisted of urns with the remains of the deceased; and then a handful of burials were identified that, due to their characteristics and decorations, reveal a higher social status. There are only five, but they have been revealing. Revealing why? Because, in addition to cremated remains, funerary trousseau was deposited in the tombs that reveal the social status that the deceased had enjoyed in the East Anglia of the Iron Age. Experts located vessels made of copper, ceramic wine amphorae, horseshoe nails, brooches and even a detailed molded glass bowl, an exceptional piece as it is probably one of the first to arrive in Britain. And is that important? Yes. Because of its origin and (above all) the history it suggests to us. “These exceptional grave goods are likely to reflect diplomatic contacts and economic exchanges between Iron Age peoples in Britain and the Roman Empire, which were already taking place before the Roman conquest of 43 AD,” reflect Angus Forshaw, one of the experts leading the UCL Archeology excavations. In the case of the amphorae, Forshaw believes they may have arrived in Britain filled with wine for local elites. As for the bowl, he believes that it was probably “a very prized personal possession” of the deceased, which is why it ended up in his grave. “The period surrounding the Roman conquest was a time of immense political and cultural change. These burials could have been a way for different Iron Age communities to signal their identity, their power and their supposed loyalty to Rome,” duck Samara King, from Archeology South-East. And now what? There is still a lot of work ahead. The experts of Archeologym South-Eastt are in charge of cleaning and analyzing in detail the different objects extracted from the necropolis. They also examine the Essex site and its dozens of tombs to learn more about the people who were buried there, especially those who occupied the most elaborate tombs. In principle, experts believe that the burials have certain parallels with others located in the area that are reminiscent of cremations discovered in Stansted and Stanway, as well as sites in Hertfodshire. Furthermore, its focus is not only on the graves. Excavations have revealed more Iron Age structures, including three previously unknown settlements with their moats, cultivation and wells spread over 11 hectares.

If you always brush your teeth after eating, science has something to tell you: you’re doing it wrong

by

“Almost everyone brushes their teeth,” concluded a group of researchers from the University of Gothenburg in 2012. The problem is that “only one in ten does it well.” The results were limited to Sweden, but from what we know They are still perfectly valid In the Western world: we spend a disproportionate amount of time and resources cleaning our teeth poorly. It’s not just the citizens’ fault. And it is that, as the BBC explainedstudies have found at least “66 different types of expert advice, sometimes contradictory to each other.” So we’ve asked ourselves… what does the available evidence say about brushing your teeth? How to brush your teeth? The most effective way to brush our teeth is one that understands why we brush them. We usually believe that we brush to remove food from our mouths; but there is something else. The teeth develop a dense biofilm (dental plaque) that surrounds them and is not easy to remove with just rinsing. We brush our teeth to manually remove that sticky layer as much as possible. To remove it from the teeth and gums, of course. There is various techniques for thisbut now we are going to focus on the most important: that “the movement should not be made horizontally, but rather the brush should move from the gums to the bottom of the tooth”, explained the dentist Juan Casado Adán. And go through all the teeth, one by one, without much pressure or haste. Oh, and by the way, after you brush, spit. But don’t rinse. If you do, most of the fluoride ends up going down the drain. How many times do you have to brush your teeth? Twice at least the experts tell us: one before we go to sleep and another as soon as we wake up. It may seem strange, but it has an explanation: saliva plays a key role in inhibiting bacterial plaque. but while we sleep we produce less saliva. Like, while we sleep, our mouth becomes more hospitable to bacteria, prior washing helps to eliminate ‘residues’ that bacteria can use to develop their activity and weaken the enamel. For this reason, the key function of washing after waking up is to renew the bacteria-laden environment in our mouth and help saliva fulfill its function. Shouldn’t you brush your teeth after meals? In reality, by using medium-hard brushes, we can brush our teeth as many times as we want. And yes, it is usually a good idea to do it after eating because this way we remove waste that bacteria could use. However, there are exceptions: if we have consumed a lot of acidic drinks (“such as soda, coffee or alcohol”), sweets or vomited, brushing immediately may be a mistake. According to Luis Cabezas Vallejo, pediatric nurseWhen the pH of the mouth is acidic, the enamel weakens and brushing at that time can cause damage (even if it is negligible). As Juan Carlos Llodra explained on ABCdeputy secretary of the Executive Committee of the General Council of Dentist Associations of Spain, in this situation it is better to wait, let the saliva neutralize the acids (or sugars) and then brush.

A study reveals that we no longer know how to say “I don’t know”

by

I notice that it is increasingly difficult for us to say “I don’t know.” Maybe it is one of the most honest acts that a person can do and, on the other hand, with the arrival of AI and with all the information at our disposal, it seems that we are losing that habit in conversations. a study He wanted to put some data on the table regarding the subject. And the conclusion reached by a group of researchers from different universities in Paris, Rome and Milan, by bringing together 3,100 participants, has been that having access to an AI, even if it gives wrong answers, pushes people to stop recognizing the limits of their own knowledge. I know everything. Recognizing that we don’t know something is more useful than we think, since it is a mental skill that prevents us from acting guided by false beliefs. The authors of the study they call her “suspension of judgment”, that is, the ability to stop before responding when there is uncertainty. As AI assistants sneak into more and more aspects of our lives, the research, signed by Chiara Marcoccia (École Normale Supérieure of Paris), Walter Quattrociocchi (Sapienza University of Rome) and Valerio Capraro (University of Milan-Bicocca), wanted to verify if the simple presence of these chatbots it alters the moment when we decide that we already know enough to answer. The experiment. To isolate the effect, the team purposely designed questions that were almost impossible for an AI to get right, with very specific visual details from movies, such as the color of the kit in ‘I Want to Be Like Beckham’ or the vehicle a character drives in ‘Like Cat and Mouse’. This is data so specific that it barely appears on the internet, so the model used in the experiment (Step 3.5 Flash) almost always failed. Participants could ask the AI ​​if they wanted, but they also always had the option of leaving the question blank or admitting they didn’t know the answer. Figures. In the group that did not have access to any assistant, 44% of the participants admitted not knowing the answer when appropriate. Among those who could ask AI for help, that percentage plummeted to 3%, according to collect the study. Furthermore, the proportion of correct answers also fell, from 27% to 9%. That is, people answered more questions, but they got much less right. The most striking thing is that, despite making more mistakes, the participants felt more confident, since according to the study, their confidence in the answers went from 30% to 76%, almost double. What if there is money at stake?. The researchers suspected that paying for getting it right (and penalizing for getting it wrong) might correct the problem. It did indeed help, but very little, because with financial incentives, the willingness to admit that they did not know the answer rose from 3% to 8%, and the correct answers went from 9% to 16%. Interestingly, the authors themselves expected the effect of AI to be weakened by money, but their data did not confirm this. And the pull towards trusting the machine turned out to be practically independent of the economic incentive. Boundaries. Capraro, co-author of the study, explained told The Register that people “became much worse” at their performance, being only one-third accurate than the non-AI group, but ended up “twice as confident” in their own answers. For the researcher, this ability to say “I don’t know” represents neither more nor less than “the recognition of the limits of our own knowledge.” On the other hand, Capraro was especially concerned about the effect that this phenomenon can have on children. According to declared In the middle, adults “already have formed critical thinking” before the massive arrival of these tools, but children who grow up using AI from the beginning “run the risk of never developing that basic ability to question an answer.” Cover image | Solen Feyissa and Dylan Gillis In Xataka | Meta warns: “We have been building infrastructure for humans for 20 years, we may have 20 months to rebuild it for agents”

Japan did not need another aircraft carrier to make a move. His next military step begins with Vietnam

by

Japan has spent decades measuring every military gesture with almost surgical caution. Not due to lack of industry, technology or capacity, but due to the weight of its recent history and the political limits that have marked its defense since the post-war period. Therefore, when Tokyo moves a piece in this area, it is advisable to look beyond the apparent size of the gesture. What we have before us shows where the Asian country is moving. The specific news. The movement appears in a statement from the Japanese Ministry of Defense after the meeting that the Minister of Defense Shinjiro Koizumi He held two days earlier with General Phan Van Giang, Deputy Prime Minister and Minister of National Defense of Vietnam. According to Tokyo, both agreed to start talks to establish new forms of cooperation in defense equipment and technology. The most striking part is the possibility of jointly developing and producing fast landing craft. Vietnam, partner without alliance. The choice of Vietnam is not coincidental. We are talking about a country whose recent history was marked by the war with the United Stateswhich since diplomatic normalization in 1995 has elevated its relationship with Washington to the rank of comprehensive strategic partnership and that, at the same time, avoids presenting itself as part of a military bloc. That combination is precisely what makes its role interesting for Japan: Hanoi needs to strengthen its capabilities, diversify partners and protect its maritime interests, but without becoming trapped in a formal alliance. In this balance, Tokyo appears as a useful, advanced and politically less strident partner than other actors. The policy of balance. This position has a very specific translation in Vietnamese defense doctrine: the so-called “four noes”. Hanoi maintains that it does not participate in military alliances, does not align itself with one country against another, does not allow foreign military bases or other countries to use its territory against third parties, and does not resort to the use or threat of force in its international relations. It is an architecture designed to cooperate without being absorbed by anyone. The maritime map. The Japanese statement does not mention China as a direct recipient of the message, but it does place the conversation in two very specific spaces: the East China Sea and the South China Sea. For Tokyo,the first is part of its major security concerns; for Hanoi, The second is the stage where they concentrate some of its main maritime tensions. That is why the two ministers stressed the freedom of navigation and overflight, in addition to respect for international law and the United Nations Convention on the Law of the Sea. Why they matter. The expression “fast landing craft” may sound minor compared to submarines, fighters or large warships, but their function is very specific: moving troops, vehicles, equipment or supplies to a coast, an island or an area that is difficult to access. In a fragmented maritime environment, with archipelagos, reefs and territories where distance is not always measured in kilometers but rather in the ability to arrive sooner, this mobility has strategic value. We are not talking about a spectacular weapon, but rather a practical tool for operating where the map narrows. Japan moves its industry. The possible cooperation with Vietnam fits into a broader transformation: Japan is trying that its defense industrial base weighs more inside and outside the country. We have seen this in the reform of its military equipment transfer rules, revised again in April 2026 to promote more defensive cooperation with allies and like-minded countries, and also in advanced projects that are still in the research phase, such as the electromagnetic railgun. The point is that Tokyo is moving away from viewing its military industry as a purely domestic matter. A very measured turn. The interesting thing is that neither country needs to present this as a breakup for it to have weight. Japan does not suddenly abandon its historical caution, and Vietnam does not sign a formal military alliance. What we see is a much more discreet formula: industrial cooperation, defensive technology and naval capabilities in an area where every small movement is read in a strategic key. That’s why landing craft may seem like a small thing on paper, but they say a lot about where the Indo-Pacific is moving.

liquid hotter than a jacuzzi

For years, we’ve associated efficient data centers with cold rooms, hallways of frigid air, and roaring machines to keep servers under control. The expansion of artificial intelligence is forcing us to review that image. The next generation of infrastructure not only has to accommodate more powerful chips, it must also keep them running without power consumption growing at the same rate. In that scenario, NVIDIA opt for a counterintuitive solution: use a coolant at 45°Ca higher temperature than many hot tubs. The reason for this change is the scale that artificial intelligence is reaching. Data centers need to run more and more operations and concentrate more computing power in less space, increasing both electrical demand and the amount of heat their systems must manage. The company led by Jensen Huang explains that energy efficiency is not only about consuming less energy, but about completing more computational work for each kilowatt hour used. This metric has become one of the great challenges of digital infrastructure. The technical answer comes with Rubinthe generation of AI infrastructure that, according to NVIDIA, is the first to reach a 100% liquid cooling. This means that not only the accelerators or CPUs are liquid cooled, but all chips and network components in the system, within a closed loop. In that architecture the fans disappear and air is no longer the element that keeps the machine stable. Heat is captured much closer to where it is generated: on the surface of the components themselves. Here appears the most curious part of the approach: a hotter liquid can help use less energy. The reason is that, if the circuit works at 45°C, the system does not need to cool the refrigerant as much before returning it to the server. NVIDIA explains that this way the heat can be transferred to external circuits and dissipate with dry coolers, a kind of large radiators, reducing dependence on mechanical cooling. In a large-scale installation, that margin can translate into less electricity dedicated solely to removing heat from the building. This is how coolant flows in an AI factory: from the distribution unit to the servers Efficiency is not measured only in electricity. One of the most important promises of the closed circuit is to reduce the water used to keep the facility operational, because the liquid is not consumed in each cycle, but rather returns to the system. According to NVIDIA, designs based on dry refrigerators can bring this consumption close to zero in suitable locations, compared to traditional systems with cooling towers that can require about 9.8 million liters of water per megawatt per year. Added to this is another less visible effect: without fans or cold air corridors, the data center begins to be a physically different machine. The aerial pipes carry the refrigerant to the servers, one of the visible changes when the air stops being the protagonist For that model to work, it’s not enough to change the building’s cooling system: you also have to redesign the server inside. The company explains that previous liquid equipment was hybrid, with GPU and CPU cooled by cold plates, but with other components still dependent on air. At Rubin, its thermal engineering team redid the liquid path to take it to more elements of the board with a cleaner architecture, based on a single input and output. The visible result is clean, sealed fronts, where air-cooled servers typically have grills, and racks capable of concentrating more computing in less space. Geography is still a part of the calculation. A circuit capable of working at 45°C expands the margin for expelling heat to the outside, but does not turn all data centers into identical facilities. NVIDIA recognizes that climate makes a difference: designing a plant in a cold area is not the same as designing it in Phoenix, Arizona, where outdoor temperatures can require mechanical cooling systems to be activated. The promise, therefore, is not to always eliminate this equipment, but to greatly reduce the time in which it is needed. So if AI is going to require more and more computation, the industry has to find ways to cool its machines without making cooling even more of a problem. NVIDIA proposes to capture heat where it is bornmove it through a liquid circuit and raise the working temperature to reduce the stress on the system. The solution, at least in this approach, is not to chase more cold, but to stop fighting with the heat as before. Images | NVIDIA In Xataka | We had a lot of fun watching robot fights.
