The US deserts have 1,200 GW solar for AI. The only problem is that Big Tech do not dare to use them

by

The Data centers They are the new 21st century factories. And like any factory, they need energy. A lot of energy. The main technology companies are building and operating Great data centers that allow offering services (video or Streaming video gamesfor example), but also where the different models of artificial intelligence. The problem is that They need more and morewhich translates into a growing energy demand. And although there are those who bet on the nuclear power and for the reactivation of fossil fuels, a study considers that the future is in the Solar energy outside the energy network. The problem is that, although the solution sounds great, it is not being applied. Hyperscalists. This is an important term. Technology companies that operate cloud computing infrastructures on a global scale are known as ‘hyperscalist’. Its data centers are crucial for the development of digital services, but also for the ‘big data’ and the advance of AI, and the term “hyperscalist” responds to those data centers can be scalar quickly and on demand. Climbing … how? Well, depending on the needs of that company and the fan that wants to cover, that scalability translates into more storage, a faster processing or a greater bandwidth on the network. Demand. The main players in this are Google, Microsoft, Meta or Amazon and although they have the capacity to expand their data centers, they are running with a huge problem: the amount of resources they consume. In large server centers, Water consumption It has always been a problem that companies have solved in different ways to be more responsible with the environmentbut the arrival of AI has been a revolution. Train and maintain these models consume a A large amount of energy resources And, apart from the water to dissipate the heat of the servers, a great energy capacity is needed. So much so, although there are companies Building more sustainable data centers At the structural level, energy demand is so brutal that They require coal and natural gas To meet demand. And some like Google either Goal they will use nuclear energy to feed your needs Energy out of the network. Contextualized the problem and seeing that these energy needs play against decarbonizationinvestigators of companies such as Stripe, Paces or Scale Microgrids have got to work to determine the best solution to feed those data centers in a sustainable way. His conclusion has been presented in a study in which they estimate that the total energy demand of the AI ​​for 2030 will range between 30 and 300 GW. In the case of the centers where AI training is carried out, that demand will be between 15 and 150 GW. It is a huge fan, but the solution they pose and that they consider optimal is the creation of micro -redes outside the network, fed by solar energy. According to them, systems with 44% solar energy are already competitive in costs compared to those based only on gas, and those that reach 90% renewable can be even more profitable than nuclear projects such as Three Mile Island of Microsoft. Green spots are green plots for a 90/10 stage Build where the sun glued. The advantage of this system is that its construction is fast because you do not have to reactivate a nuclear power plant. You are not tied to what the energy market demands, Geopolitical conflicts They do not leave you without supply, it is clean energy, buy solar panels is getting cheaper And, above all, it is easily scalable. If more energy is needed, it is as simple as adding more panels, but the most important thing in this equation is that they can build these centers in optimal places. Unlike servers centers, which do need to be close to the end user to offer a better service, the data centers in which the AI ​​training is carried out have geographical flexibility. This implies that they can install them in areas with optimal solar radiation and in places where the land is cheap. Optimal areas Optimal areas. In the study they have identified plots in the United States with a potential for up to 1,200 GW of solar energy outside the network, with gas support and an optimal area with large esplanades and radiation during a large percentage of the year. So, CaliforniaNevada, Arizona, New Mexico and the east of Texas They would be ideal places to house those data fueled data centers outside the network by 90%, with the remaining 10% backed by gas. Beyond this, the study points out that most of the appropriate land is private, so it can be purchased to build these facilities and that, in addition, many are within lands that would allow subsidies. If you start today, the construction bond would be between 12 and 24 months and everything seems positive, but it is not being done. If it is so good … why isn’t it? According to researchers, there are three issues that come into play. Two are closely related and have to do that this of AI training is a very recent phenomenon. The designers of the data centers have historically been skeptical when it comes to getting off the network because what they wanted was to enhance, above all, the reliability. They can’t stay a second without energy, go. Related to the historical tendency is inertia: it has never been done before, although current technology would allow to operate only with renewables (as some countries already do). And the third reason is the cost, $ 23 per MWh, specifically. The panels are increasingly affordablebut it is more expensive than not buying those panels -evidently. However, the researchers point out that this extra cost would be dampened by the Cost of emissions and compensation that would be avoided in the short term. Therefore, these solar micro -lands outside the network seem a quick way to feed large -scale data centers, but although technology is mature, it seems to spend time until … Read more

We have been looking for the definitive cure of allergies for years and we have not yet solved the big problem: understand them

by

The end of the rains and the arrival of good weather have, for many, a dark back: The allergies. Spring, and especially the months of May and June, brings us the pollen proliferationone of the most important allergens, the main cause of sneezing at this time of year. The most common way of treating this type of allergies is through antihistaminesdrugs aimed at blocking the effects of histaminea neurotransmitter that also plays an important role in immune system. Recall that allergies are nothing other than a reaction of our immune system to external substances that understands as dangerous and that are not really, allergens. Antihistamines are very useful when treating allergic symptoms. But one thing is that, and another thing is to definitively cure these disorders. Today we do not have A cure for allergiesbut at least there are some routes open to hope. So close we are to achieve it. Perhaps one of the first treatments that come to mind when talking about healing the allergy are vaccines. What we understand today as vaccines against allergy are immunotherapy -based injections, and its logic is not far from conventional vaccines: it is about administering a small amount of what causes us allergy capable of alerting the immune system without unleashing an allergic reaction. While they are a useful treatment in many cases, they do not finish solving the problem, so we will need periodic injections that will improve the response capacity of our immune system. What ways are there open? Almost ten years ago, We commented on some of the open research lines in the search for a cure for allergies. These ways included, for example, the “biological therapies.” These are therapies that focus on antibodiesthe proteins that our body produces when it detects substances that it understands as harmful. This type of treatments They are still One of our great hopes. An example of this is omalizumab, a drug in principle aimed at combating asthma and approved two decades ago in the United States. In recent years, science has been validating this therapeutua option. A recent example is in A study Posted in 2022 in the magazine Clinical and Translational Allergy. In this analysis, the team observed that the drug was effective when preventing spring allergic rhinitis. Understand the problem To understand how our knowledge has evolved in recent years, we must first understand why it is so difficult to find a definitive cure. The background problem is simple: We do not understand the allergies well enough to find a solution. We still do not understand why certain people suffer from a certain allergy while others suffer from another type of reaction, at the same time that others do not seem to have such problems. We don’t know either Why allergies are permanent despite the fact that the antibody that we generally associate with them does not usually remain in our body for long periods of time. Two studies Published last year in the magazine Translational Medicine Science They can help us understand this situation a little better, explaining at least this last point. The answer could be in an antibody that we usually do not associate with allergies, immunoglobulin G (IgG), and the cells that produce it. What the teams responsible for these studies discovered is that some cells responsible for producing IgG produce immunoglobulin E, which is associated with allergies, when they run into an allergen. The key to allergic “memory” could therefore be in these cells. Before going better, everything seems to indicate that the allergies problem will go worse. And is that every time More people suffer This type of disorders. There are several factors that could be, independently or together, behind rapid ascent in the number of allergic people in the world. One of these hypotheses is that of hygiene. Since our immune system is “trains” through exposure to external agents, the absence of these agents in early stages can imply that our system does not perceive them as normal and, exposed in later stages, ends up reacting disproportionately. s From the environmental point of view, we must also consider the presence of pollutants in the atmospherelike particular matter. These pollutants can also affect our airways, combining their effect with that of conventional allergens and aggravating the situation.

Aemet’s big question is if 2025 will definitely end the drought

by

Today, the great meteorological issue of Spain has names and surnames: the May bridge. Will it heat? Will it be cold? Will it rain? Will it sunbathe? The good news is that we have the models working. The bad is that this time they do not serve much. As Aemet explainsin recent days the chances of raining during the first days of May have been exactly the same as the chances of the sun shine and it is hot. The same. But that’s not the worst. A matter of time. And, although it is difficult for us to accept uncertainty is something that usually happens. “This is the atmosphere”, Roberto Granda says With all reason. In the background: it is inconvenient, but it is a matter of time. In fact, predictions begin to leave the balance to the rain side. And in a few days, we will have a much clearer scenario. Trends, on the other hand, paint another month for water. Although as the month ends, the forecasts are lightening the amount of rainfall, the European center Paint a good part of the Peninsula With more rains than normal throughout the month. If right, we will chain three months of relatively anomalous rains. Above all, if we compare them with the springs of recent years. What implications does all this have? Has drought dead? If the great weather question is May, the weather is drought. Because, Despite black pointsthe truth is that water reserves They are already 75.56%. That is, more than 10% above the historical average of the last decade. If 2024 laid the drought, 2025 is determined to end her. After all, we came from years where spring was very dry, very warm, very stable and that turned increasingly long summers into a counterreloj race against it “zero day“: The day we simply run out of water. The rains of these months change the stage completely. The authorities are already levacing all measures against drought And they prepare Transvase equivalent to double the annual consumption of an entire autonomous community. The problem is that, in much of the country, it has been the longest drought period of modern history. The country’s wounds go beyond water in swamps. Not surprisingly, in recent years, deforestation has done only devour southern Spain. The end of the drought (of a long period that began in 2013) is excellent news; But above all, it is a very precious time to rethink in front of the existential threat of climate change. That is the third big question: if we will do it. Image | ECMWF In Xataka | Current water, luxury: two thirds of the earth are already running out of reservations

Chrome’s extensions have a big problem. Anyone can buy them and fill them with malware without finding out

by

One day John Tuckner decided to try to be evil. He found a browser extension called “Website Blocker” that could buy for $ 50 and took it. The extension, which allows to block certain websites so that the user is not distracted with them for some time, was especially interesting because it allowed to reuse it for spam attacks. And then things happened. Sight problem. In just a few days I had control of the extension and could do what I wanted with it. He modified the code, published the update and confirmed that the novelties had reached all users without being found. And then told what was happening: He is the founder of the cybersecurity company Secure Annex, and wanted to confirm their fears: there is great danger with extensions: anyone can buy them, modify them and reuse them for all kinds of purposes. Google reviews the modifications, but “it is not clear about what level of scrutiny,” Tuckner explained. Another recent case. At the end of January the creator of the Browser Boost Extra Tools for Chrome extension sold this development and transferred it to its new owner. Its 30,000 users were soon exposed to the new code, which dynamically redirected websites that the new owner decided unilaterally. I have not been. One of the extension users He warned of the problem in the github repository of the extension and analyzed the code notifying the danger of malware that could reach due to the new owner. The creator, n0m1111, explained who had sold the extension months ago and was no longer responsible for the code. Playing with permits. These extensions often allow permits of all types of browser parameters. Tuckner explained how in the extension he bought a permit called “declarativemetretreQuest” was used that was very wide and allowed to redirect users to false authentication sites to steal their passwords. Other permits would allow the owner of an extension to take screenshots with sensitive information or access the cookies that the browser keeps to steal data from the browser sessions. The possibilities are multiple and in Xataka we already talked a few months ago about how extensions They are becoming a silent method to infect users. A recent attack. In February, the Gitlab Threat Intelligence expert team They discovered A group of 16 Chrome extensions “used to inject code into browse to facilitate advertising and SEO fraud.” Among them they added 3.2 million users, and in Gitlab confirmed that the extensions had been bought and then modified, which allowed to avoid suspicions by users and the industry itself. These experts notified Google of the problem, and the company eliminated them all in January 2025. Block extensions, the solution. If you want to protect yourself from these problems, the solution is block The execution of extensions in your browser, especially in computers that handle sensitive data such as work. Unless they are extensions of trust, these types of problems can cause serious security problems. Care with permissions. Browser extensions can end up being bought, sold and reused without notice by their new owners, as has been the case. That raises a serious problem for users and companies, which before installing an extension should provide A lot of attention to permits that ask for these extensions to work. What do they say in Google. In Xataka we have contacted Google responsible and we will update this article if we receive new data on the subject. Be that as it may, the company offers A HELP DOCUMENT In this regard and also indicated in a Article in your official blog How to stay safe with the use of extensions in Google Chrome.

The Big Tech are collapsing in the stock market. The question is which one that can best survive tariffs

by

Since 2025 began, goal has lost 14.6% of its stock market value. It is just an example, because Nvidia already lost already 30% and Apple, the most affected by tariffs, has lost 33% of its market capitalization. In view of the situation, a thing is clear: all technological ones are falling. The question is whether any of them can better survive this debacle. A quarter to oblivion. The re -election of Donald Trump as president of the United States seemed to sit very well to technological companies. However, the decision to initiate a global commercial war has made the panorama change radically, and in these first months of the year the balance has been very negative for large technology companies. Apple, the one that goes worse stop. The situation was already bad, but yesterday USA announced some 104% tariffs for Chinese importsand that had an immediate impact on a particular company: Apple ceased to be the company with the greatest market capitalization in the world. Right now it is very close to Microsoft, which occupies the first place, but the markets of the market and the measures that the different countries are taking pose a future with a lot of movement in those market capitalizations. The “Seven-Ya-No-Tan-Magnifices”. Apple, Microsoft, Amazon, Alphabet, Meta, Nvidia, and Tesla are the prestigious members of the group known as the “Magnificent seven.” These seven great technology are among the 10 most valuable in the world, but all of them have been especially affected by tariffs. However, there are better prepared than others to face this crisis. The hardware penalizes. One of the first side effects of tariffs will be the increase in production costs. This especially affects companies that have a strong manufacturing component of hardware devices. That is one Great disadvantage for Applewhich also manufactures in Asian countries in which tariffs are especially high. It is not the only one with that handicap: nvidia – which It depends on TSMC In Taiwan for much of the production of its GPUS— or Tesla —With China and Mexico as manufacturing partners – they will also be especially impacted in this section. And logistics chains. These tariffs are also an obstacle to the logistics chains of these companies. Geopolitical tensions could exacerbate these conflicts, producing delays in production or supply of materials and components. Apple is again a perfect example of this logistics complexity: globalization came from pearls, but this new situation does not favor its strategy. Amazon is another problematic case for its gigantic commercial network of physical products, many of which are imported from China. Microsoft can survive better. The company does not have a hardware -based business, and Azure, Office 365 or its video game platform (Xbox) are not so hardware dependent. The diversification of its income and its focus on cloud services favors its competitive position, and in fact is one of the least market capitalization has lost these months: 17.7%. Amazon also benefits from the strength of its cloud infrastructure with AWS. And the cloud, what. We have talked about how Microsoft and Amazon do not depend so much on the hardware and apparently that favors them, but you have to be careful, because their infrastructure and data centers depend on hardware components that will end up costing more (like everything) and impacting the business. Something similar happens with Google, centered almost absolutely on the cloud and services and that has a lot of weight not only in the US but in EMEA. The danger of tariffs to services. Among the reprisals that we can live in the next few days is that of the tariffs that the EU proposes for digital services. That is the great export of the US, and the Big Tech are their producers, so companies such as Alphabet, Meta, and to a lesser extent Apple, Microsoft and Amazon could be harmed. He Panorama for investment in AI is complicated Also, and Big Tech can be seen doubly threatened. Image | Egor Myznik In Xataka | The United States has been fantasizing with an “made in USA” iPhone.

The Big Tech have played their whole future to AI. Tariffs are going to test that bet

by

The world economy makes waters. The geopolitical and economic hurricane called tariffs It is affecting especially to large technology companiesthat fall remarkably in the stock market. There are many problems derived from that value of value of the Big Tech, but among them there is a remarkable one: the future of AI. Apple in low hours. The tariffs have just entered into force, but it is also that the US has officialized the 104% tariff to China. The global commercial war intensifies, and has already left a great loser: Apple has ceased to be the most valuable company in the world. This is the current situation of companies with the greatest market capitalization on the planet. Source: CompaniesMarketcap The great AI actors, in danger. But curiously Apple has not invested much less in AI and its rivals. Microsoft, Nvidia, Amazon, Google and Meta have suffered significant losses in recent weeks. Tariffs have been the decisive factor so that in 2025 they accumulate a negative balance that goes from 14.6% of the 33% of Apple according to data according to data from CompaniesMarketcap. This is not about the debated “AI bubble”. It is true that all AI companies have wanted to sell us the message that this technology was going to change everything. At the moment that has not happened and some talked about a potential “AI bubble“, But what is happening with tariffs is something very different, and does not help at all the future of this discipline. This table, created on February 10 for Xataka, indicated the market capitalization percentage that Big Tech would dedicate to capital expenses (CAPEX). The photo has changed in terms of the percentages, and we will see if it also does it as to those amounts. Capex in danger. Two months ago we talked about how Apple was the company that Less capital expenses (CAPEX) would have in 2025. In front of it, colossal investments and a common discourse: almost all those thousands would be focused on creating data centers for AI. Now those investments are in danger, because all these Big Tech can end up disincurning to mitigate the effects of tariffs on their account books. The AI ​​was already expensive, and now it will be more expensive. Being able to take advantage of the functions of AI means using the enormous resources of the data centers of those Big Tech. If the tariffs cause the dreaded and expected price increases in these infrastructure, that will make it cause Use ia more expensive For users and companies, which can lead to a drop in its use and a slowdown of its development. If everything is more expensive and the expense is trimmed, so does innovation and work in new AI models. Fear of investing. Investment companies, such as risk capital, can also be very affected by this panorama and start Measure very much Your future investment in AI startups. That is another danger to the evolution of a market that until now had taken advantage of Optimism and unbridled expectations about AI. And without so much investment once again the appearance of new startups and the rhythm of innovation can be clearly braking. Risk of recession. The consultant JP Morgan I already esteem that the risk of the US to enter recession in 2025 is 60%. In these periods, companies prioritize financial stability over innovation, which can decelerate the pace of technological innovation. A study A year ago of Deutsche Bundesbank and the Bank of Finland showed how a 1% drop in GDP can reduce investment in innovation to 0.3%. Precisely JP Morgan revealed that US GDP could fall 1% in the third quarter of 2025 for this circumstance. Image | Jamie Street In Xataka | The Copilot+ PC promised a revolution.

We have tried them and they are not good news for big hands

by

Naturally, certain aspects of a device do not reveal all its possibilities until they are tested. This is the case of the Joycon of The Switch 2 In mouse mode. Although its operation was very clear in Nintendo’s ads (the Joycon, turned with the back towards the table, can move like a mouse, with trigger and buttons turned into buttons), its possibilities have not been clear until The presentation in Paris, Where we have been able to feel them. Many mysteries have been resolved. Two tests. And so it has been thanks to a couple of games that we have commented on our Review to the titles presented In this pair of days, but that we are going to review with a little more detail, because that is where the keys of the command are. It is, on the one hand, by ‘Metroid Prime 4: Beyond’, where the right command acts as a mouse in a First Person Shooter; And in ‘Drag X Drive’, where both are used at the same time with a purely Nintendo style, that is, in a way that would never have occurred to us, and squeezing the possibilities of the device based on lateral thought. In search of precision. The goal of playing a First Person Shooter With mouse is the search for precision in the pointed one: the saga ‘Metroid Prime’ traditionally solved the problem that the control with command (heir of time in which it was not usual) with a system of Lock-on of the point of view in the enemies. But now, thanks to the new command, ‘Metroid Prime 4’ is more precise than ever before in the saga. The Samus Aran’s settings movement is executed in this case with the left hand, holding the Joycon half as a conventional console command, while the right hand points. For small hands. What is the problem? The size of the control used as a mouse. For large hands such as mine, the grip position that forces to adopt the pseudo-oatón leads to a certain grab that ends up becoming annoyance in a few minutes. Especially if, as in this case, the side buttons must be clicking on the side (which make Samus a sphere or activate the way of scanning objects) twisting the fingers, because they are too together. It is a command that, obviously, has been designed first as PAD: the arrangement of the buttons is comfortable when used in classic mode. As a mouse is an extra use. One solution: alternate the mouse mode. But Nintendo has thought about everything, and the Joycon have a special characteristic: it is not necessary to activate the mouse mode in a menu from the game, but simply disconnecting the control of the console and placing it on the table. Employment as a mouse is immediate, and this allows us to use the right hand as a mouse when more precision is exiled, in the parts of action; and volting it again to its original position, to explore. That is the alternation system that suggested: of course, it can always be done with a mouse or always with sticks, and each player can find the one that most interests him Basket Fever. This discomfort is nuanced, curiously, with ‘Drag X Drive’, the curious wheelchair’s futuristic basketball game that is mandatory with the two joycon as mice. Although sometimes the game has a certain air of technical demo, it is very hilarious in large part by its control system, based on firm movements of the mice on the table, which mimic the movements of the players controlling the wheels of their chairs. The robustness and, at the same time, the versatility of the controls (which allow us to accelerate or turn our chair with enough immediacy) stand out in a game that, not demanding the precision of a ‘metroid’, does not generate so much discomfort in the controls. An intermediate solution. The usefulness of these mouse controls will be outlined, without a doubt, with the appearance of new games, or giving renewed life to ancient titles such as Bethesda’s ‘doom’. Our current feeling is that it is more a Gimmick (such as the camera) or an extra that a proposal that allows an intensive and prolonged game, as is the pro command. But as is logical, the more options exist for a very varied, the better. Especially if, for once, it is included in the price, no one is going to charge an extra for using this grip.

Trump tariffs have caused the Big Tech debacle in the stock market. And propose a slowdown in investment in AI

by

Apple shares closed almost 224 dollars yesterday. When the session is opened in Wall Street they will have fallen suddenly and porrazo more than 7%, up to 208 euros. That collapse will be the greatest among the Big Tech, but all of them They will be affected Notably for Tariffs announced by Donald Trump. And that makes another danger derived: that of investment in AI. Big tech fall to lead. As they point out In CNBCApple will leave more than 7% more to open the session in the US Stock Exchange, but others will also have very notable falls. Nvidia fell 4%”After-Hours” (after the closure of the markets), Tesla 4.5%, Alphabet, Amazon and goal between 2.5%and 5%, and Microsoft 2%. Thus Apple’s actions closed yesterday, and so they will begin the session at Nasdaq today. Source: Google Finance. Tariffs everywhere. Falls are due to tariffs announced yesterday by Donald Trump. The US president indicated that these import taxes would be “a declaration of economic independence” for his country. Base there will be 10%tariffs for all imports, but certain countries will be especially punished: China will have 34%tariffs, Vietnam of 46%, the EU of 20%, Taiwan of 32%, and Japan of 24%. The US is the great world importer. The huge consuming machine that is the United States makes the country the largest importer around the world. According to the Department of Commerce in 2024, the country spent 4.1 billion dollars in goods (3.3 billion) and services (814,000 million) imported. With these measures precisely wants countries that export more to the US to pay extra for being able to do so, but it can cause a dangerous domino effect. What about AI. Projects such as Stargate raise a colossal investment of 500,000 million dollars To create AI data centers in American field, and here the importance of semiconductors is evident. The United States will need to import chips and other components and materials to create these centers, and manufacturers such as NVIDIA or TSMC will precisely be affected by tariffs. Or continue to manufacture outside the US and pay tariffs or They create factories on American soil to avoid them, something that for example TSMC is already working. Tariffs with the point of sight in AI. In fact, a good part of the components and GPUS necessary to create these data centers are imported from Taiwan, Mexico and China, which are three of the countries that will be punished by tariffs. The punishment for these imports is remarkable, and can lead to a slowdown in the development of AI. Investments in danger. The investment in data centers is colossal by the Big Tech, and we have the example of Amazon that plans to dedicate most of its 2025 capex of 100,000 million dollars In these developments. How will tariffs condition that investment? Difficult to know, but both for Amazon and for the rest there are now new problems to make investment. That are added that perhaps They were oversized first of all.

Nintendo Switch 2 will have “Key cards”. And the big question is what it is for the future of physical format

by

On June 5 it will be launched Nintendo Switch 2. In a one -hour event, the Japanese company has Clear almost all doubts That there was on its new console, but beyond being a celebration and although the presentation has been an avalanche of games, the aftertaste that has left among users is bittersweet. Nintendo Switch 2 will be retrocompatible with Siwtch 1 game cards, but to enjoy improvements We will have to pay. The price of the console will start from 470 euros in Europe (but in Japan it will be much cheaper so that more people can buy it, saying by Nintendo). And physical games They already go to 90 euros. In social networks, the conversation revolves around something else: the ‘Key or’ Game Key Card ‘Nintendo Switch 2. And it is a concept … controversial, at least. The “Key Key Card ‘Game Cards” Nintendo Switch 2 During the presentation, there were elements that Nintendo did not detail. For example, to know the price we had to enter the Nintendo Store, the same for the price of the games. And when he talked about the formats, the company just said two things: That the game cards will be the same size as those of Switch, but will be red and will read data at a higher speed. That normal microSD cards will not be compatible, since it will be necessary to buy microSD Express cards that read data at a speed, again. It is logical, because more demanding games at the visual level need storage support with a higher reading speed to be able to do streaming of data without interruptions. What did not say anything is one of the ‘game key cards’. Again, it is after the presentation when we find out about this matter, and it is the one that is raising blisters among users on social networks. In the Nintendo Support Pagethey say the following about this third alternative format to the physicist and digital: Game key cards are different from normal game cards since they do not contain complete game data. Instead, the game key card is your “key” to download the full game to your console through the Internet. After completing the download, you can insert the game key on your console and play as you do with a normal physical game card. They also show an example of the notice that will be in the physical cover: The operation is simple: we buy a box with this cartridge-lave, we introduce it in the console and we are given the possibility of downloading the game associated with it. The cartridge has no informationso the game is saved in the MicroSD Express that we have bought separately and will be from where it is executed. When we want to play that game, we will have to put the corresponding cartridge-lave, be connected to the Internet the first time we start it (subsequent starts do not need the Internet, but the cartridge-llave is already playing. It is a mixture between physical card and digital game. What is the point? The only one that occurs to me is that it is for games that have a higher weight to the maximum of the game cards or for small editors who want to have physical pretence in stores (although more caught with tweezers this). But of course, it also gives rise to another interpretation: Nintendo kills the conventional physical format. . Too much fog, but with precedents on switch Nintendo says clearly: “The game key cards are different from normal game cards, since they do not contain the complete game data” and “This is a box of a game key.” There are no need to clarify it, but these phrases would imply that, on the one hand, the normal game cards will be and, on the other, the key cards. There will be games that come inside the card and others whose card is simply an ‘activator’ For the game that you download from the eShop. Nintendo has said that Siwtch 2 game cards have a higher reading speed. If they are just an activator, it wouldn’t make sense, right? Supporting this theory, we have ‘Cyberpunk 2077’. Your responsible They affirm The following: “Nintendo Switch 2 owners can buy the game on a 64 GB game card or by digital download in the Nintendo Eshop.” The other interpretation, however, is that the “game key cards” are those of Switch 2 and the “normal game cards” those of Switch 1, which would imply a death of the ‘pure’ physical format on the new machine. And that is why it is mandatory to use MicroSD Express cards in Switch 2, because everything will go on them. That is the reading that is being done in networks and the one that gives rise to the company itself due to the diffuse messages. Currently, Nintendo already offers boxes that do not wear the game. An example is the ‘code in a box’ like that of ‘It Takes Two‘ either ‘Final Fantasy VII‘, Boxes that are in physical format, but do not have a game card: only a code to download them from eShop. On the other hand, titles like ‘Noire‘They have a giant notice of “requires Internet download.” I had not done the test until now, since I always had my connected switch, but I have put the game on the console, I have removed the connection to the network and … I can’t play. Basically, at least that is what it seems, that new notice of the Nintendo Switch 2 boxes makes it more clear that, or you have the Internet, or do not play that specific game. With the case of ‘La Noire’ I thought it was a certain additional content or some chapter that did not enter the ‘cartridge’. And it may be so, but the truth is that it does not let me play without downloading the data before. Other cases, such as the ‘Heritage Pack’ … Read more

This fly larva turned his ass into the head of a little one. The big question we have now is how it will be adult

When we think of camouflage in nature, images of Octopos that melt with the seabed, of SEPIAS or chameleons. There are other tactics to confuse possible predators, such as Butterflies that mimic patterns in the wings to confuse birds or Palo insects. But there is an even more committed case to go unnoticed: that of a flip larva that has turned its butt into the head of a termite. And it works so well that the termites until they feed. Fluke. What seems an adorable creature in the main image is, in reality, the rear of a blue fly larva. It has false antennas, but also false eyes, an impressive morphology adopted with a single objective: to confuse the termites. And the finding has been made … by chance. Researchers from the Institute of Evolutionary Biology, the CSIC and the Pompeu Fabra University were studying butterflies and ants in the Anti-Atlas mountain range, south of Morocco. However, like They explain In the publication of the IBE, as the butterflies did not fly due to the heavy rains, they began to look for ants. “When we lift a stone, we found a termiter with three fly larvae that we had not seen before.” Shut mask. They themselves affirm that it was a “casual finding”, but really special because, after it, they made three more expeditions in the area and, “despite lifting hundreds of stones, we only find two others, together in another termitter.” In it study Published in Current Biology, researchers develop their surprise with these larvae that have developed “a unique costume”. Located on the back of the body, the bluefly larva shows a “termite mask” with a non -functional head that has an antennas, palps and eyes extremely similar to those with a great trine harvesting. Those eyes have a function, but very different from what we might think: they are the holes for which the larva simply breathes. Twin. As they explain, most termites live in extremely dark environments on termiters at meters deep, so they do not need eyes at all. The harvesting termites, however, go to the surface to collect grass and have functional eyes, something that these larvae mimic with their spiracles. 3D camouflage. The specimens are curious, but they would really have to define them as fascinating due to two extremely unique details. One is that they not only have antennas in that false head, but throughout their body, as if they were tentacles. Researchers estimate that it is something that facilitates simultaneous communication with several termites inside the termiter. As you don’t see there, the termite that rubs to the “narrow” larva the tentacle of the false termite and thinks “ok, is mine.” But … do they only use touch? The truth is that not because, apart from being felt, the termites have a unique aroma that allows them to identify themselves as the same colony in the galleries of their home. And here comes the other fascinating detail: the larvae imitate that aroma and smell exactly the same as the rest of the termites. Each colony has a distinctive aroma, something that these larvae also have and that researchers have described as a “chemical costume.” They even give it porridge. “The larva is not only tolerated, but constantly communicates with the termites,” says Roger Vila, one of those responsible for the finding. He also speculates the possibility that the termites themselves feed the larva (through their functional head, yes), but it is something they are testing. In one of his photographs you can see that possible mouth -to -mouth food. Accelerated evolution. Vila comments that it is not so weird that there are flies that are made by other insects to carry out forms of social parasitism. For example, humpback flies also imitate the termites, but in that case they are adults, and not the larvae, the protagonists. It also indicates that the common ancestor between both flies dates back to more than 150 million years ago, “much more than what separates human beings from mice, so we could affirm that we have discovered a new case of evolution of social integration,” he says. In addition, he points out that the blue fly larva would have evolved very quickly to adopt these forms. Complications. Vila emphasizes that discoveries like this help to be aware of everything we do not know about the diversity and specialization of insects, but also comments that studying these laboratory larvae is something that seems extremely complicated. The larvae studied ended up dying without reaching metamorphosis in the laboratory, which indicates that, either recreate the conditions they have in the termiter in the desert is crucial – something very difficult – or there is some other element of the nest and the symbiotic relationship between species that is crucial for the survival of the specimens. We will see what they end up discovering, since now the mystery is not only to know if it is a unique larva, but how it will be in its adult form.
