create mental categories as a small child

by

For many dog ​​owners, the your pet’s ability to understand words As ‘ball’, ‘Paseo’ or ‘Chuche’ is a reason for astonishment. But now what dogs can understand a new leap, to move on to compression that goes beyond associating a sound with a specific object. Something that A study Published in Current Biology, it has seen in after its investigation, where they have concluded that dogs can have communication capacities so far reserved for humans. The investigation. The study has been led by Claudia fleet An exceptional group of dogs known as ‘Gifted Word Learner’. Some dogs that are not common at all, since they have an extraordinary talent to learn the names of the objects, with vocabularies ranging from 29 to more than 200 words, one, enables that allows them to learn names of objects quickly in playful interactions with their owners. Learning the rules. To find out if dogs can go beyond simple visual recognition, the researchers designed an ingenious four -phase experiment. The first one focuses on dogs learning what they will have to do. To do this, the owners taught their dogs two verbal labels for two toys groups. For example, a set of four objects were assigned the ‘throw’ label and the only interaction was the game of the strip and loosen. Another set of four toys was given the “launch” label, and with them it was only played to throw them so that the dog would bring them. The crucial thing in this case is that toys within each category did not share any systematic physical characteristic. The only thing in common was the label and the way of playing with them. The exam. The second phase was to verify if the dogs had come to understand well the rules that had been previously taught. Eight dogs exceeded the test successfully, recovering the right toy with at least 12 of 16 attempts. New toys. The third phase was undoubtedly fundamental and is the ‘kit’ of the matter. Here the owners introduced completely new toys for dogs and for a week they played with them in the two ways already established above but with a very strict rule: verbal labels of ‘throw’ or ‘launch’ could not be used. The dogs only experienced the role of the toy, without anyone saying their name or for what they were using it. The fire test. Once all these phases were made, only these new toys were left (with which he had played without appointing it) with other family toys. The owner from another room not to give visual clues asked the dog ‘bring me a’ throw/throw ‘. The dog at that time had to deduce which new toy the owner referred to with this instruction, based solely on the function he had previously experienced with him. Results. The dogs selected the correct new toy, the one with which they had played in the manner corresponding to the label, with a frequency well above chance. On an average of 48 attempts, the dogs hit 31 times. This clearly demonstrates that dogs were not limited to learning the names of individual objects. Instead, they created two “mental categories” based on the function of objects: one for ‘throw’ toys and another for ‘launch’. When they met a new and nameless toy, they were able to assign it to the correct category based on the use that was given. This ability to generalize a label to functionally similar objects, ignoring appearance differences, is a fundamental pillar of language development in children. In fact, this ability emerges in young and preschool children, who learn to understand that both a ceramic cup and a plastic glass belong to the ‘glass’ category because both serve to drink. The importance. This study is pioneer especially to demonstrate that a non -linguistic species can perform a functional classification linked to the learning of verbal labels, and does so in a naturalistic game context and without having to undergo a lot of repetitions in a laboratory environment. Until now you could think that dogs worked through perception, but this study comes to change this idea we had. In this case, the fact that animals classify the world mainly by perceptible characteristics such as shape or color is challenged. These dogs were based on the ‘planned utility’ of the object. In this way, GWL dogs are emerging as an unprecedented animal model to investigate cognition precursors related to language in ecologically valid conditions, offering parallels with child learning. Open a door. The authors themselves point out that this ability is, for now, exclusive to these “gifted” dogs and should not be generalized to the entire canine population. However, it opens the door to investigate whether this capacity is latent in other dogs and what cognitive mechanisms support it.

The Machada del One overcoming the container record on board

by

Much of the world economy moves by boat. HE esteem That between 80% and 90% of merchandise trade around the world is transported by boat, and to sustain that spine, we need huge ships. There the Porteneroauthentic titans that seem a lie that are maintained on the water and that are capable of transporting, of a tacada, a couple of tens of thousands of large containers. There are no larger ships than the “new” Megamax class. And within it is one who has just burst the transport record: The One Innovation. Megamax. It is the largest class of modern boring partners. It emerged as a natural evolution of the ULCV, or ‘Ultra Large Container Vessels’, because it seems that wearing 20,000 TEU was not enough for current trade. Teu means ‘Twenty-Foot Equivalent Unit’, a standard for containers that allows us to compare between ships and that means that if a ship can transport 20,000 TEU, it can move 20,000 containers. If the ULCV moved that amount, the megamax can between 21,000 and 25,000 TEU, being able to load 24 rows of containers … wide. It is an absolute barbarity and is touching the limit of what a channel like Suez’s can house: if they were wider, accidents could occur Or, directly, Do not go through the channel. And taking into account the Importance of these few points in world tradeor widen the passages, or accommodate the ships … One Innovation. Is the name of Third type of largest container of the world. Its capacity is 24,136 TEU and is only behind the OOCL Spain (and the rest of the OOCL megamax class) with its 24,188 TEU and the MSC Irina (and the rest of the MSC Megamax) with its enormous Capacity for 24,346 TEU. To house so much load, the dimensions They are up to it: 399.95 meters long. 61.4 meters wide. Depth of 33.2 meters. 16.5 meter draft. It is like a Empire State Buildingbut horizontally and floating. And it has the ability to transport 25 container levels (imagine a container pyramid, go), with 24 rows along, another 24 wide and 2,000 of those containers having connection with cooling systems. The other ships look like toy Record. Reaching the maximum capacity of each ship is complex. In fact, the three mentioned are extremely similar in size, but that one can with 200 containers more than another respond to issues of logistics and internal organization rather than to the dimensions of the ship. How to play a game of ‘Tetris‘Superoptimized, ultimately. Well, despite being the one that has the most capacity, the One Innovation has just beat the capacity record on a trip. Again. If a couple of years ago you already set the 22,000 TEU brand, this September He did it again with 22,233 teu loaded in a single operation in the port of Singapore (One of the most important on the planet). Complex logistics. In terms of capacity, it represents 92% of their maximum, so they can continue experimenting to load even more. Now, this is not something that can be done in any port. The One Innovation is designed for the Asia-Europa route, being able to stop in strategic ports such as Xiamen, Singapore, Rotterdam, Southampton or Algeciras. It is a connection between the main Asian and European centers, for which a very specific machinery is needed that manages to load and download huge amounts of containers. And this is something that not all ports are designed or can face. We talk about channels about 20 meters deep, cranes of about 70 meters of range and lengths between 450 and 500 meters so that ships can dock. That without counting the necessary defenses in case there are accidents or calculation failures. Necessary (and we will surely go more). As we say, ships of this size are necessary and are constantly used both for efficiency when moving a lot Energy efficiency. Instead of making multiple trips, in one and thanks to that massive capacity, it can move load through the world. In addition, they seem essential if the wishes of the ‘are fulfilled’New Silk Route‘That China is promoting to create more efficient trade routes between Asia and Europe, but also with Africa, a region in which China has enormous interest both for its resources as for enhance markets such as cars.

The Spanish rice has come out in the most unexpected country in Europe: England

by

Spain is one of the great rice producers in Europe. The annual production of this cereal is around 800,000 tonsa significant portion of 2.8 million tons produced in the European Union. Now a new country could be incorporated into the list of European producing countries (although it comes late to join the Union list).It is the United Kingdom. A crop making their way. The rice cultivation He makes his way in England. An experimental rice plantation is demonstrating the viability of the cultivation of this cereal in the relatively fresh and humid climate of the British islands. Nine varieties. The experiment It is being driven by the UKCEH (UK Center for Ecology and Hydrology) and for a marriage of local farmers, Craig and Sarah Taylor. The experimental rice cultivation occupies four plots of a land in the FENS region, in Cambridgeshire. In this region of the East English, marshes and peat areas predominate. The soil in this region is not only rich in nutrients and conducive to agriculture but also offers, thanks to peat, the possibility of creating floodplains such as those required by rice cultivation. The four plots occupied by this experimental crop have been sufficient to cultivate nine varieties of rice, including rice originating in Brazil, Italy or the Philippines, varieties used for plates such as risotto, Basmati rice or sushi. With the help of heat. Cultivating rice in the British climate does not seem like a great idea, but the results seem to indicate otherwise. It may have contributed the exceptionally warm summer that has affected the British islands. The future of rice cultivation on the islands could depend on the heat lived this year being a simple anomaly or fruit of a trend marked towards increasing temperatures. “We could never have contemplated that this grew here,” explained to the BBC Sarah Taylor, one of those responsible for this project. “Not in a million years,” Apostille Craig, her husband. Tying the carbon. The mob plays an important role in carbon regulation. This soil originates in the decomposition of organic matter and stores a large amount of carbon. The degradation of these soils as a result of agricultural use implies the emission to the atmosphere of huge amounts of carbon dioxide. The rice planting project He wants to avoid thisTying the carbon to the terrestrial peat of the English region. This implies that the project not only has the potential to help adapt to change in the weather, it is also a way to mitigate the emissions that cause it. New competition? Climate change involves numerous challenges and perhaps one of the greatest has to do with agriculture. Changes in temperature and rain patterns imply that the crops that once prospered in one place stop doing so. On the other hand, change also open the road to the introduction of new crops where they would have been inconceivable before. In a changing context, rice crops in Spain raise a double threat. On the one hand, The drought lived a few years ago It was a threat to endanger the supply of water in areas such as the Ebro delta. In case that were not enough, the rainy episodes we have seen in the last year have also brought New threats to cereal producing regions.

China’s government is discovering that selling cheap cars is not enough in Europe: spare parts will be insured

by

China has proposed an objective: to become the New energy cars supplier of the world. HE esteem that the country exported about 4.3 million cars in 2024, of which 1.6 million were electric and almost 750,000 ‘They parked‘In some country in the European Union. Within China’s expansion policies, companies have made the decision of flood Europe with its cars. For this they are associating with already consolidated groups In our territory, but they have also opted for the most direct way: bring your cars directly in large ships and open dealers. It is what is allowing the expansion of brands like byd, Xpeng or Jaeco/omoda (and Those who are coming, like Xiaomi), But there is a problem: spare parts. We already told it a few days ago: the mechanics were Starting to see Chinese cars with good eyes. Even Euro NCAP, the agency responsible for giving a security score to cars in our territory, Consider that they are safer than many other brands. They are not the only ones: the CEO of Riviain has already said that Chinese cars were better And even Jim Farley, CEO of Ford, commented that He didn’t want to get off his Xiaomi Su7. The problem is when something fails And it’s time to ask for the replacement piece: you have to wait because you have to ask and, sometimes, that piece is easy for you to come … from China. Now it is the Chinese government itself who wants to settle that problem with a goal in mind: take care of the client. And for this they will regulate sales abroad through the ‘export licenses’. Export licenses, China’s weapon to improve the image of their cars In September 2012, China implemented a regulation called ‘Shang Chan Fa N318’ regulations. With it, a series of qualification requirements for national manufacturers were established that requested both cars and motorcycles. It was something that applied to both hybrid and combustion vehicles, but the electric were exempt. If companies could export everything they wanted without any regulation, Isn’t that good for expansion? Yes … and no. On the one hand, the aforementioned expansion is achieved, but irregularities could also be committed, a poor after -sales service and an absence of official guarantee were offered. Basically, “anyone” could bring the car, sell it and disregard. And there is the negative part, since if a user buys a car, fails or does not update and does not have any attention after the sale, that experience will not only do not return to Buy a Chinese carbut recommends not doing it. With the new export license that It will be implemented As of January 1, 2026 for cars that leave China, the government seeks to combat all that. And be careful, not only to Chinese manufacturers, but to companies that manufacture in China, regardless of its origin. In fact, four ministries are those who have jointly announced the measure (trade, industry and information technology, customs administration and the state administration for market regulation) and what companies that manufacture in China will have to do in China and want to sell their vehicles in other countries It will be to request a license that will be renewed annually.

His new “party” are working 92 hours

by

In Silicon Valley, the new generation of young entrepreneurs has left behind the parties at which alcohol rivers ran. The example that follows is that of the big names of Silicon Valley, such as Mark Zuckerberg, Elon Musk, Sam Altman or Bryan Johnsonwhich prioritize their business projects ahead of their own social life. The phenomenon is not isolated, and more and more young entrepreneurs share the same mentality: “Why go to a bar if I can be creating a company?” Summarizes Emily Yuan, a young founder of Silicon Valley, In an interview for The Wall Street Journal. The data does not lie: alcohol consumption Among the youth of generation Z It is being reduced and, in the scope of Silicon Valley startup incubators, the norm is increasingly and not exception. Silicon Valley’s new habits. The daily routine of those who aspire to success in Silicon Valley is marked by working hours that exceed the usual. According to what was published by The Wall Street JournalMarty Kausas, 28 years old and founder of the startup Pyloncommented in a LinkedIn publication that chained several weeks in a row of 92 hours of work and that canceled his vacation because the stress of work prevented him from taking A few days to rest. However, in Another publicationthe young entrepreneur ruled out that in his company a “culture of 996” was applied for his employees, in reference to the new Asia export trendin which you work from nine in the morning to nine in the afternoon and six days per week. What is fun? The main paradigm change that shows this group of very young technological entrepreneurs is to define What is fun. In his case, and as Marty Kausas and Emily Yuan detailed, what they consider fun is not to spend some time with friends drinking some beers. “Our motivation to start a company was fun and adventure. But what is fun for us is quite different from what is fun for others.” That concept, together with the messages against alcohol that are giving some influential figures of Silicon Valley, such as Sam Altman, which has manifested himself totally contrary to alcohol consumptionor Mark Zuckerberg that, Unlike your cowsjust drink beer on few special occasions and what is necessary To take the photo. In general, for “Tecnobros“From Silicon Valley alcohol and parties no longer enter the concept of fun. Sobriety in the tech era. Generation Z, globally, is reducing alcohol consumption worldwide. The data They point out that there was a drop in alcohol consumption of 4.5% per year since 2011, and has been stabilized since then. According to him last report of health the average consumption of each adult in Europe went from 12 liters per year in 2000 to 9.5 liters in 2019, and if we focus on wine, the only alcoholic beverage that drinks Jeff Bezos In special celebrationsthe Data point to that its average consumption per adult has fallen from 14.2 liters in 1990 to 10 liters in 2017. In the “new garitos” there is talk of financing This decrease in alcohol consumption has been associated with a cultural change in the social activities of these new entrepreneurs. The meetings between colleagues, formerly animated by toast and drinks, are now meetings in Saunas, motivational talks or gym routines in search of professional connections. Miranda Nover, co -founder of a fitness startup called Fort, said In an interview for Business Insider That the image of ascetic existence is very important for young entrepreneurs. “You are trying to transmit: we do this six days a week in the office, we work until 9 pm, we do not drink, we do not party, we do not do any of that.” The businessmen of the future are “Healthy”. Unlike what happened with the previous generations of Millionaire Founders, such as Henry Ford or Aristotle Onassis, in which alcohol ran to all its parties. Now, alcohol consumption has ceased to be the central axis and a closer philosophy has been adopted to the Millionaire’s postulates Bryan Johnsonto focus all the energy on productivity. In San Francisco’s artificial intelligence events, alcohol is absent. According to Michelle Fang, 26 years old and event organizer for these Precotes founders of Silicon Valley, among the reasons why at the parties of the Entrepreneurs quarry is not only for a Change in the concept of leisure And health: “Many events related to AI do not serve alcohol, not only because it is out of fashion among the San Francisco public. Many founders are not enough to drink.” In Xataka | Alcohol is no longer cool: the “arrogance curious” movement is turning the abstemious into a trend Image | Unspash (Nguyễn hiệp)

Printers have been a terrible product for 30 years. The fault is Nash’s balance

by

Let’s go back to 1949. A young mathematician named John Nash Find an original idea for your thesis at Princeton University. Game theory already existed thanks to the previous works (1944) by John Von Neumann and Oskar Morgenstern, but the von Neumann model focused on zero -sum games (one player wins, the other loses). Nash had a spark of genius in proposing that in any game there should be at least one point where no player could improve his situation by changing his strategy unilaterally. Formalized that idea in a short two -page article (‘Equilibrium Points in N-Person Games‘) In January 1950, and with it revolutionized history. Including printers. Is the printer the worst technological product in history? And is that the printers is an almost manual example to apply the call Nash balance. These types of products have been following – at least, to a large extent – the economic model of the machin and blades: you sell cheap the first, but face the second. Consumers know that when we buy an ink printer, the price will be economical, almost ridiculous. But we also have assumed that ink and cartridges for those printers will be very expensive. And if they are not, what will end up being is Ink subscription… either to the printers themselves. Not only that: in the last 30-40 years we have seen how printers have become-probably- The worst technological product in history. It is no longer only that printers can get stuck or work erratically. The real problem is terrifying form in which manufacturers have protected their business, preventing in all possible ways that users can for example use Compatible cartridges and tonniers of third parties. Nash’s balance explains very well why manufacturers do what they do. Imagine two great manufacturers such as HP and Canon with two options: Expensive and blocked cartridges (current model) Cheap and open cartridges (which allow competition and lower prices) Given this situation, HP and Canon managers know that three types of market situations can be found: If both keep expensive and blocked cartridges: they earn a lot If one “opens” its cartridges and lowers prices and the other remains closed: the one that opens loses income and the one that is still closed earns more … or the opposite. Whatever happens, one will end up winning a lot and the other losing a lot. If both open: there is strong competition again, but both win less Given that scenario, manufacturers make an inevitable business decision: they close their cartridge technology and sell it face Because that’s what gives more benefits to everyone. Nash’s balance is fully fulfilled here: it describes a stable point for each player (company) but does not ensure that the result is the best for the whole. Collectively and from the social point of view, the optimal would be to open the technology and lower prices: companies would earn less, but the market would be larger and fair. Reality, as we know, is very different. But maybe that reality can change. We need a “Tesla printer” The printer user has therefore 30 years constant bleeding which translates into an exaggerated expense in cartridges and also in an erosion of time and productivity. What has happened with printers is something extraordinary: We have normalized that printers are almost more a problem than a solution. The Open Printer, a striking printer project “Open Source” and is based on the use of HP cartridges but accepts compatible third -party cartridges. Source: The Open Printer. And that is why we have a panorama in which there is a great opportunity for a revolution in the printers market. This segment is hungry for an ethical disruptive: the manufacturer who abandons the current Nash balance can change everything here. It is a mature field in which an innovative based on transparency and reliability could not only capture the market, but even redefine it. What the market needs is a kind of “Tesla printer”. And we refer to a printer that causes in this segment what Tesla managed to provoke in the car industry: a machine that has a great design, a reliable operation and that is also designed to last. But above all, that offers an alternative to current printers and their dictatorial philosophy with cartridges. Here are some projects underway. The project The Open Printerfrom the Parisian startup Open Tooks, is intended as A repair ink printer, Open Sourceand that focuses its operation on reparable cartridges. Its creators claim that this printer is created “with standard mechanical components and with modular parts”, which theoretically simplifies its assembly, modification and repair. Source: The Open Printer. In fact, the Open Printer works with a small Raspberry Pi W plate as an operations center. There are no proprietary firmware or cartridges with DRM. It is designed to use HP63 cartridges (HP 302 in Europe) both in black and in color but they serve both those of HP and third parties. And not only can you print on AAR or A4 folios, but even in 27 mm paper rolls. There are no details about its price or availability for the moment, but the idea will not be launched directly, and will first be launched as a collective financing project. We know for previous failures (and frauds) that such financing models It has its risksbut in this case that option seems reasonable and we only have to wait for the best of the project. That may not be the only launch in this regard, and in fact There is an even more interesting rumor. Frameworkthe company that has conquered us with its repairable laptops, seems to be considering the idea of ​​creating its own printer (modular and repairable? We expect that!). This is how at least a recent message indicates in X in which they commented on how “one of you must have sabotaged the office printer and has forced us to manufacture one. It is not possible that HP is selling printers that broken.” … Read more

The place where Maradona is a deity

by

Naples, the city that for decades was Synonym of Maradonaoverflowing passion and persistent shadow of the camorralive an unexpected transformation today: hordes of tourists invade her by changing her identity at a dizzying pace. What was previously a landscape of football, mafia and popular life has become a decoration for selfies, endless queues and tourist floors that expel the neighbors. A mirage. Yes, Naples, vibrant and chaotic city, has become In symbol of how mass tourism transforms to the most recent traditions into prefabricated products for visitors. The Pulcinella statueignored for years by Neapolitanos themselves, was high to folk rite Thanks to the invention of influencers and today It concentrates endless tails of tourists looking to rub their nose in search of good luck. For the premises, the paradox It is evident: It is a tradition without roots, consumed as an empty show. Thus, the Historic Center of the City, once a community life fabric, It is described now by activists such as an outdoor theme park, where stores, bars and souvenirs They have replaced To everyday life. The silent eviction. The most palpable impact is observed In the house. The proliferation of tourist rentals has transformed entire neighborhoods into A B&B MOSAICexpelling families with decades of roots. In some popular districts there is already a tourist accommodation for every three homes. The evictions multiply and many inhabitants are replaced by passage or students. The History of Giuseppe Gigliowho lost his home when his landlord decided to convert the building in tourist apartments, reflects a systematic process: homes cease to be homes to become speculative assets. The phenomenon is not limited to small owners: much of the market is in the hands of companies or large lessorsand the profits rarely remain in Naples, flowing to richer cities in the north or even abroad. Showcase. The transformation does not only affect housing, but also Urban identity. Streets that were cultural axes, such as Via Toledohave been filled with identical restaurants and tourist businesses, replacing historical bookstores with taverns or thematic bars. The multiplication of fast food stores has exacerbated Waste problems and has reduced community life to constant consumption, while homeless or the most vulnerable neighbors are pushed outside the center. Even churches, in the past centers of community life, have been relegated to mere Visitors attractionslosing its function of place of worship. The result is a less habitable city for those who support it and flatter for those who visit it. A political problem. Local authorities They recognize The magnitude of the challenge, but denounces that they lack tools to act without a national legal framework. The attempts of some regions of limiting the number of tourist floors have been blocked by the government Central of Giorgia Meloni, who defends the “market freedom.” Even new laws, such as The urban reform Promoted by Matteo Salvini, they have facilitated the conversion of housing in tourist accommodations. Thus, the regulatory vacuum converts the center of Naples into paid terrain For speculationwhile traveling to its neighbors towards the periphery. A paradox. Tourism defenders argue that they create opportunities and jobs, and in some cases it has allowed families to escape poverty by turning floors into B&BS or opening bars. But the problem arises when the entire economy of a neighborhood It depends on a tourist flow that can fade, as demonstrated by the Recent descents In arrivals. The lack of a “plan B” leaves small entrepreneurs at the mercy of a volatile market, which can evaporate as fast as it arose. Ironically, some tourists already They start complaining that the city feels too homogeneous, saturated with repetitive food stores and experiences designed only for them. Identity erosion. If you want also, which attracts visitors (authenticity, street life, cultural mixture) is precisely what is most threatened. The risk is that, instead of a living city, Naples becomes An empty decorationa showcase that is consumed and abandoned. Without policies that balance the protection of residents with tourism management, the city is in danger of losing what makes it unique. As They warn Activists and academics, what is eroding is not only urban space, but the right of Neapolitans to remain protagonists of their own city.

Drastically reduce the consumption of data centers is crucial for AI. And China has had an idea: to submerge them in the sea

by

China is About to submerge a data center In the sea, near Shanghai, as a solution to a problem that we will gradually begin to see more: Great energy consumption of the AI. The installation, which will come into operation in mid -October, is one of the first commercial projects of this type in the world and points to a new way of cooling servers without depending on traditional cooling systems that devour electricity. The background problem. Data centers are the backbone of the Internet and AI, but They generate huge amounts of heat. Keeping them refrigerated by air conditioning or evaporation of water consumes a brutal amount of energy, and with the rise of artificial intelligence, the demand of these facilities has shot. China seeks to reduce the carbon footprint of this critical infrastructure, and its commitment It goes through sinking it underwater. How it works. The yellow capsule that They have built Near Shanghai houses servers that remain cold thanks to the ocean currents, without the need for active cooling systems. According to Yang Ye, vice president of Highlander, the maritime company that develops the project with state companies, “underwater operations have inherent advantages” and can save approximately 90% of the energy for refrigeration. The installation will extract almost all its electricity from nearby marine wind farms, with more than 95% renewable energy. The technical challenges. Putting servers under the sea is not easy. They must be protected from the corrosion of salt water, for which they use a special coating with glass scales on the steel capsule. Also They have installed An elevator that connects the main structure with a section that remains on the water, allowing the access of maintenance equipment. Another challenge is to build the Internet connection between the Submarine and Tierra Firme Center, a more complex process than with conventional facilities. Universities researchers in Florida and Japan They have warned In addition to these centers could be vulnerable to attacks by sound waves driven by water. Environmental doubts. Although the project promises to reduce emissions, questions remain about its ecological impact. The heat emitted by servers could alter the surrounding marine ecosystem, attracting some species and driving others. Andrew Want, marine ecologist from Hull University, Point out That “these are unknown aspects at this time, sufficient research is not yet being carried out.” Highlander says that an independent 2020 evaluation on its test project in Zhuhai indicated that the water remained well below the acceptable temperature thresholds, but Shaolei Ren, an expert from the University of California in Riverside, warns That climbing these centers will also climb the heat emitted. There are few precedents. Microsoft tested this technology off the coast of Scotland in 2018, recovering the capsule in 2020 after declaring that The project had been completed successfully. However, he never marketed it. The Chinese project advances with the support of government subsidies: Highlander received 40 million yuan for A similar project in the province of Hainan in 2022, which is still operational. The installation of Shanghai will serve clients such as China Telecom and a state computing company of AI. What comes now. Experts agree that these underwater centers will probably not replace the traditional ones, but will complement the existing infrastructure in specific niches. According to Rencurrent projects seek to demonstrate “technological viability”, but much remains to be resolved before a massive deployment. What is clear is that, if these types of projects face all technological challenges and manage to greatly reduce the energy consumed of the data centers, it will be a great point in favor for the company that manages to provide its solution in the AI ​​race.

Encell has everything to house extraterrestrial life. And Europe is moving to discover it before anyone else

by

When NASA’s Cassini probe sent the first images of the water vapor jet That world was not dead. It was on, and the content of an underground ocean was expelling to space. Since then, Each new satellite data He has reinforced an idea that excites astrobiologists: if there is a place beyond the earth where to look for life, it is there. Short. A new Cassini data analysis, collected almost twenty years ago, has reinforced the possibility of Encelado to meet all the conditions to house life. The European space agency is clear: Encell is already a central objective of its long -term exploration plan, and it is time to launch a mission to answer the big question at once. The ingredients for life. For life to exist as we know it, three things are needed: liquid water, energy and several basic chemical elements: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. Once all seems to have them. We know that a global saltwater ocean is hidden under its icy cortex. The energy is provided by the friction of the tides that Saturn causes and, probably, Hydrothermal sources in the seabedsimilar to fumaroles that here are full of bacteria and more complex organisms, such as worms and snails. Promising news. Thanks to the brain speakers, who launch samples to space, Cassini was able to analyze the composition of their ocean. Although most of the essential elements had already been detected, including phosphorus, a new finding between probe data has re -raised enthusiasm. A study published in Nature Astronomy Analyzes a Cassini flight from 2008. The ship crossed the brain feathers at 18 km/s. That speed, which seemed like a problem, turned out to be useful: the impact broke the molecules in a way that allowed them to identify them better. The result has been the discovery of new complex organic molecules, such as aliphatic compounds, esters, ethers and other molecules with nitrogen and oxygen. On Earth, these molecules are linked to reactions that give rise to amino acids, the basic pieces of proteins. ESA plans. With such promising scenario, Europe does not want to be left behind. In his scientific road map Voyage 2050, Encesto is already the star destination for a future mission. The idea includes an orbiter and a landing module. The orbiter would fly over the brain feathers several times with more precise instruments than Cassini. The landing would pose near the “stripes of Tigre” of the South Pole, where the geysers emerge, to directly collect the newly fallen snow. It would be the first time that a probe analyzes a world with an active ocean, although it would not reach the surface until 2058. Europe is not alone in the race. The United States also has its proposal: the mission Alcamadus orbilandermarked as a maximum priority in the Survey decadal of 2023. Your plan is very similar: orbit first and then land. China, meanwhile, already works in nuclear technology for deep space probes and Enced is among its future goals.
