The two most important weather models in the world are discussing whether Santander is going to freeze next week. And the cold is winning

by

Where has all the cold gone? So far this fall (with the sole exception of Siberia), temperatures have been relatively mild on all continents. And it seems that the situation is going to continue like this: it is true that the forecasts speak of a progressive decrease in temperatures in the southeast of Canada, the eastern United States and northern Europe; but no model paints a scenario that is particularly cold (except some very long term prediction). However, all eyes are on the polar vortex. If the models are right, it is very possible that the vortex will experience an unprecedented disturbance in November, leading to an interesting weather period starting in December. “There is no way this is fulfilled.” While November continues with its strange meteorology, the models draw increasingly strange scenarios. At this point in the week, we cannot rule out that on the 18th and 19th we have a more than considerable winter storm with the ‘beast from the east‘looming over Western Europe. In the next few hours we will have a war between models: The American marks a cold entry on Santander, the European said no. Little by little, the two seem to be converging towards a cold scene. It’s too early to say, but in a very few hours the daisy will be shedding its leaves. Anyway, the central issue is that all of this is minute sin. The breaking of the vortex. Except for that event in the middle of next week, autumn will continue to be very warm and mild on almost all continents. However, this could change if sudden stratospheric warming appears. That is, the vortex breaks. Sudden stratospheric warming? To understand it simply, we have to remember that the atmosphere is a kind of “lasagna of air layers” and each of them follows its own logic. That is, they work quite differently and independently. As far as it affects us: the circulation of air in the troposphere (the one closest to the surface) and the circulation in the stratosphere (the layer directly above) are related, yes; But, in general terms, they each do their own thing. During the “sudden stratospheric warming“, a part of the troposphere warms rapidly and, as a consequence, invades the stratosphere, causing a profound alteration of the circulation at high altitude. That is, for a few days, everything turns upside down. And what happens? The most common consequence of this is that the polar vortex weakens and may break down. The polar (arctic) vortex is a current of air that runs from west to east around the north pole and contains cold air at high latitudes. When this current is strong and stable, preventing it from flowing towards places like Spain. If the vortex It destabilizes and its winds lose strength (due to, for example, “sudden warming”), it is relatively common for cold air masses to escape on their way south. What if it doesn’t break? In reality, the vortex does not even need to break. It only needs to move from the Arctic region to lower latitudes. By moving a huge mass of cold air with it, the result is always very similar: an icy cold that can turn any country upside down (even the best prepared ones). And that seems to be what we are going to see. It’s hard to know if it will affect us or not, but there’s no doubt that the late fall weather is getting “interesting.” Image | Meteociel In Xataka | The last hope of winter in Spain is desperate, but increasingly possible: the breaking of the polar vortex

While OpenAI takes all the media glory with ChatGPT, Alibaba is already taking important clients with Qwen. The latest: Airbnb

by

Alibaba has been investing in its family of open language models for quite some time.qwen‘, which are gaining increasing acceptance between developers and users. Although OpenAI takes all the media glory with ChatGPT and the rest of the services, the Chinese firm is not short and already is overtaking him with some clients. The latest example: Airbnb, which has chosen to rely mostly on Alibaba’s Qwen AI model for its automated customer service, leaving ChatGPT in a secondary role. Airbnb’s decision. Brian Chesky, co-founder and CEO of the tourist accommodation platform, explained Bloomberg this week that his company “heavily relies” on Alibaba’s Qwen model. As he admitted to the outlet, ChatGPT’s integration capabilities “are not quite ready” for Airbnb’s needs. On the other hand, Chesky assured that Qwen is “very good, fast and cheap.” It is curious, especially considering that Chesky is a personal friend of Sam Altman, head of OpenAI. How the system works. Airbnb’s customer service agent, which the company deployed to all its users Americans in English last May, is built on 13 different AI models, including those from OpenAI, Google and open source providers. However, Chesky recognized that, although they use the latest OpenAI models, “we usually don’t use them much in production because there are faster and cheaper models.” Just like point the company, the system has allowed them to cut their human workforce by 15% and claims to have saved average resolution time, going from almost three hours to just six seconds. Open source is gaining ground. Open source models, which developers can modify as they wish, are increasingly challenging closed systems like those from OpenAI. Although the company also has an open model (gpt-oss), Chinese tech companies are releasing models much faster, more cost-effectively, and open source. Joe Tsai, president of Alibaba, declared recently that the winner in AI should be determined by “who can adopt it the fastest,” not “who creates the most powerful model.” A future integration with ChatGPT in the air. Although Airbnb is awaiting the development of ChatGPT app integrations and could consider a collaboration in the future, similar to those of its competitors Booking and Expedia, the platform is not currently among the first applications available on the OpenAI chatbot. Chesky even advised to OpenAI about its new ability for third-party developers to integrate their applications into ChatGPT, a feature that the company announced this month and which he described as a “developer preview.” And now what. Airbnb plans expand its AI agent with support in Spanish and French this fall, and 56 more languages ​​next year. Meanwhile, the company claims to be betting on new social functions to foster connections between users and improve travel recommendations within the application. For Chesky, these features are “probably the most differentiated part of Airbnb.” Cover image | Unsplash (Oberon Copeland), Wikimedia In Xataka | OpenAI is no longer a startup. Now it is a black hole of 500,000 million that threatens the world economy

When the Titan submarine exploded there was nothing left to rescue. Except one very important thing: a memory card

by

It has been more than two years since the Titan submarine tragedy and the story continues to make people talk. The last thing we know is that the recovery teams found the camera that was part of the submarine. The camera was damaged, but inside it housed a memory card from which they were able to extract image and video files, although none from the implosion. The discovery. Youtuber Scott Manley told it in your X account. In a series of posts, Manley has published several images of the camera’s recovery report detailing its characteristics and condition. It was a Rayfin Mk2 Benthic underwater cameracapable of submerging up to 6,000 meters deep thanks to its titanium body. Although the case appeared intact, the sapphire crystal lens was shattered. Upon disassembly, many of the components had light damage, but one of the boards included an SD card that was in good condition. The content of the card. Investigators and forensics managed to make a duplicate of the card and extract the contents. In total, they obtained nine images and twelve videos. However, the camera had been configured to save the captures on an external storage device, so it did not contain any images from the day of the fateful dive, but rather they were images taken at the Marine Institute in Newfoundland, which was where the missions to the Titanic departed. In the images they have shared you can see the facilities and some underwater images, but at shallow depths. Catastrophic implosion. The Titan left Newfoundland on June 16, 2023. An hour and 45 minutes had passed when communication was lost, but it was not until four days later that the coast guard found the first remains of the vehicle and confirmed what they suspected: it had imploded. They found remains of the vehicle, but no body of the five crew members could be found. It was avoidable. The Titanic is located at a depth of 3,800 meters, where the pressure is 380 atmospheres. There is vehicles capable of reaching this depth and even more, but the Titan had a long history of problems and his own Former director of operations called the tragedy avoidable. In fact, several members of the underwater exploration community, including James Cameron, They had written a letter to OceanGate where they expressed their concern and assured that they were “going down the path of catastrophe.” The company ceased its activity after the accident.

The city of Las Vegas bet everything on mass entertainment. Now he only lacks the most important: tourists

by

In the summer of 2023 it seemed clear that something had changed in Las Vegas. The data They corroborated it: the “city of sin” had fewer clients than in 2019, but in return Much more money squeezing your visitors as never before. Since then until now, drifting towards exorbitant prices for anything has done nothing but grow. The problem is that he has done it at the same pace that lost the most important thing: the tourists who supported her. Neons cemetery. I told the weekend in A report The New York Times. A few steps from the strip, in a plot where old marques rest, the condensed history of Las Vegas can be read: pink feathers of the Flamingo, the red martini of the Red Barn, or the dancing shirt of a dye frequented by Liberace. This Neon Museum Remember that the city has managed to reinvent itself again and again, from that to the game, of gastronomy to the sports show. However, the present does not distill so many “vibes” as turbulence. The imitation elvis, almost empty coffees and European tourists who are surprised to pay one hundred dollars for a breakfast They feed the feeling that the world capital of excess goes through a stage of uncertainty. A descent as a warning of something worse. Recent figures from the Convention and Visitors Authority talk about a 11% setback In the volume of visitors in a single year. What happens in Las Vegas resonates beyond: experts like Andrew Woods They warn that the city works as an advanced barometer of the US economy. In other words, if the Vegas cools, the country could be at the gates of a broader brake. The fall is perceived In details: nightclubs without queues, gondolas sailing empty in artificial channels and half -filled card tables. The Canadian facor. One of the most sensitive blows comes from the north. Canada, which contributes 1.4 million visitors a year, has reduced In almost 20% His trips, dragged by commercial and diplomatic tension with the Trump administration. He Canadian boycott Threat to subtract hundreds of thousands of tourists from the final numbers of 2025. For a city where the international clientele represents the oxygen of hotels, restaurants and shows, that absence translates into less busy rooms and revenues that evaporate. Price bubble. The other great wound is in The traveler’s pocket. Room prices have gone from an average of $ 120 in 2019 to more than 160 this year, with peaks of more than 1,000 in luxury hotels, to which are added resort rates of 50 dollars daily and tickets to shows that exceed 300. After The “Revenge Travel” From postpania, the industry got used to it To collect expensive. Now, in a context of uncertainty, that strategy is perceived as greed and dissuades the average visitor. The buffets of 29 dollars gave way to banquets of 90, and even a simple bottle of water or a parking lot have become Symbols of increation. The crossroads of identity. The city had always maintained a balance between luxury and accessibility. But today the balance leans towards the exclusiveleaving behind that tourist who once found in Vegas an affordable destination. The risk is clear: lose the essence of “theme park for all” and become An unsustainable bubble. Voices such as Guy Martin, veteran contractor, defend that prices respond to mathematics and not to greed, remembering that structures Like Sphere or the Allegiant Stadium cost more than 2,000 million each. Others, as Caesars executives, admit that the industry “went from enthusiasm” after the pandemic. Global comparative. The Las Vegas dilemma is not unique. Macao, who in the last two decades displaced Las Vegas as the world’s world capital in terms of income, A collapse in 2014 When Beijing imposed restrictions on capitals from the Chinese continent. The city then turned to diversify with family tourism, conventions and shows, and although it recovered muscle after the pandemic, the dependence of the visitor of high purchasing power remains an Achilles heel. Dubaifor his part, he opted for a radically different model: Instead of lowering, it has consolidated a premium destination with massive infrastructure and a global luxury story. But even there, price inflation and event saturation generate similar tensions. Both examples show that raising indiscriminate prices can turn the destination exclusive, but also fragile and vulnerable to geopolitical or economic changes. Persistence, nostalgia and uncertainty. Despite the storm, andn the Times remembered That there are faithful visitors who are still considering the city of their ritual refuge, such as Mary Reyes and her husband, who have returned twice a year for decades and barely notice the difference. He neons museum It symbolizes that duality: the city of a thousand reinventions that never ends, but that today hesitated before him Dilemma of your future. Will you be able to recover the vibrant and affordable destination image, or will it become a prohibitive enclave for majorities? The outcome will mark whether the Las Vegas brightness continues to dazzle the world, or if the bullshit signs of the museum cease to be a relic to become an omen of so many other cities with the same bet.

Science has reviewed everything we know about sleeping well. The most important thing is the most obvious: light

by

In a saturated world of ‘life and gadgets that promise a perfect break, since face mask until Mantas with weightscience reminds us that the key to have a good sleep quality It is not in the product that appears in Tiktok, but in have a good sleep hygiene. And this happens to synchronize with our internal biological clock, what we know as the circadian rhythms. A concept on which it continues to be investigated and that allows us to know how our body is scheduled to sleep. The issue in this case is that modern life, with its artificial light and its chaotic schedules, It is the main enemy of these rhythms. And therefore of ourselves. A business. The market that exists around products that promise to help us have a better rest, the truth is that it generates billions of dollars a year. A figure that is logical, since nobody wants to spend the night and be the next day asking for coffee for the corners. And to avoid this we many times turn to whatever we see that they tell us that it works. However, many of these remedies are not only ineffective, but can be counterproductive. Andrew Mchill, a scientist specialized in circadian rhythms of the Oregon Health & Science University, warns That failed attempts can discourage people to seek professional help, worsening the situation. The solution. If we stick to science, the solution is completely free. The key is in Understand and respect our internal biological watches. A system of ‘watches’ that is present in each cell of the organism and that needs to be synchronized with the ‘central clock’ of the organism that is in the hypothalamus and specifically in the supraquiasmatic nucleus. To do this, this nucleus receives light signals that come through the eyes by the optical nerve that allows you to synchronize vital body functions such as the sleep-vigilia cycle and the production of hormones such as melatonin, which, which it is increasingly important Beyond allowing us to reconcile the dream such as repairing the data in our body. With a small nuance of basic physiology, Melatonin production It is suppressed or inhibited due to light collection. At the time the environment darkens, the pineal gland begins to release melatonin. And his mismatch has consequences that go beyond morning fatigue by affecting cognition, mood and reaction time. The contrasts. One of the keys is in the light as we have said, especially in the blue wavelength. This makes the daytime light rich in these blue tones, Synchronize our circadian rhythms throughout the day. But when the night comes and we are on the couch watching the last Instagram or Tiktok reos this blue light of the screens makes our body end up dislocating. Literally, with this constant exposure to the blue light we are indicating the body that is still daytime and that has to be underway and not decay. Something that ultimately triggers the hated insomnia. A study of Global Health Institute of Barcelona (ISGlobal) He warns that overexposure to the “blue light” of electronic devices alters our sleep-vigilia cycle when interfering with melatonin production. The solution, according to experts, is to seek contrast: expose ourselves to natural light during the day and reduce exposure to artificial light at night. A simple outdoor walk or work near a window can make a big difference. At night, it is advisable to lower the intensity of the lights, turn off the screens or use applications that adjust the color temperature to warmer tones. Or even bet on red lights that does not interfere with melatonin production. Meals. Our digestive system also has its own schedule, causing hormones that cause or inhibit hunger, digestive or even Insulin itself also works by rhythms. This makes eating on the undo, especially late at night, alters these watches and can cause digestive problems, an increase in body temperature and an increase in glucose levels, which makes sleep difficult. And it makes enough sense. When the end of the day is approaching and the sun begins to wear, the body begins to prepare to sleep, reducing insulin, which is a fundamental hormone to control blood glucose levels. In the event that we give us a binge during the night, we are causing these insulin levels to have to rise compulsively when the body is going down. Something that completely dislocates to the body. The recommendation is to follow what you have surely heard: “Breakfast like a king, eats like a prince and dinner like a beggar.” The last meal of the day should be at least three hours before bedtime. The consistency. Sleep The right time is as important as the amount of hours we sleep. Our body has an optimal sleep window, which varies according to our chronotype (if we are “evening” or “morning”). However, work and study schedules often force us to ignore our biological clock. The Spanish Sleep Society (SES) He insists on the importance of maintaining regular sleep schedules, even on weekends, to keep our circadian rhythm synchronized. The generalized use of alarmrs is proof that most of us live in conflict with our constant biology. Seek help. Something very important in these cases is to seek help from professionals in the event that the biological clock is completely uncontrolled. In many situations, exogenous melatonin can be administered at high doses accompanied by a plan to improve sleep hygiene. But beyond this, Mayic Mayic It offers different tips that can be obvious how to create an adequate rest environment, exercise regularly, control food and especially establish the most appropriate relaxation routine. Although clearly getting away from the screens and maintaining an adequate schedule is the most recommended so that we can finally sleep peacefully.

YouTube can end up becoming something more important for Google than your search engine

by

The race to dominate the AI It has many legs And, one of them is undoubtedly developing The perfect search engine. There is also a clear intention of several technological giants by Destrone Google in one of your most prolific businesses. However, Google is not passed without doing anything while the AI ​​career advances by leaps and bounds. In fact, it has an ace in the sleeve that perhaps few have seen coming: YouTube. And it is that the video platform could become the most powerful weapon of the company to continue growing in AI. The searches conquer. Google knows that artificial intelligence can be an existential threat to its search engine, the main source of income of the company for decades. That’s why he has been vitaminating Gemini and joining his abilities to Search through summaries with Ai overViews either The full search engine with AI that the company plans to launch soon worldwide. Meanwhile, chatgpt and other language models eat the toast with very useful capabilities for users, such as being able to answer user questions directly While searches are made On the Internet without clicking links or advertising. A perfect shield. However, YouTube works radically differently, since here the AI ​​is not a threat, but A competitive advantage. And while the search engine must deal with chatbots from other companies, YouTube can use AI in its favor to generate more content, improve its recommendations algorithm and, above all, multiply their monetization opportunities. All this knowing that it is a platform without any serious rival to date. Video against text. Analyst Ben Thompson, from the specialized media Stratechery, Point out That video is an inherently more monetizable format than the text, and the recent history of social networks demonstrates it. Twitter, Facebook and Instagram began as text and photos, but they have all ended up focusing on the video because it is what really hooks most users. Tiktok understood from the beginning: The most addictive content does not come from your contact network, but from an algorithm that shows you the most entertaining videos, wherever they come from. And YouTube has been doing exactly for almost two decades. Numbers that speak for themselves. YouTube It is the most watched streaming service on televisionsahead of Netflix. It is the dominant mobile application and computer for video consumption. And, above all, he has paid More than 100,000 million dollars to creators in the last four years. That figure does not even include the income that creators obtain for collaborations with brands, which usually overcome what they earn by advertising. YouTube is no longer just a platform, but an entire economy AI as an accelerator, not as a threat. Google is integrating the technology of its Deepmind division directly on YouTube, and the results are promising. The platform He has just announced tools based on I see 3its video generation model, which allow any user to create clips for YouTube Shorts from the mobile and for free. The result? A content tsunami generated by AI That, although mostly it will be irrelevant, annoying and ends up subtracting authenticity from the platform, it will also generate more videos in less time and, in large part, their tools can be used so that creators use them to generate really good videos. And YouTube already has its own algorithm to separate the grain from the straw. Each element of a video is a business opportunity. But Google’s master play with AI on YouTube has nothing to do with creating videos, but by monetizing them. The company has started trying A system that uses artificial intelligence to automatically identify products that appear in the videos and label them at the exact moment in which they are mentioned or shown. “Each element of each YouTube video is on its way to becoming a monetizable surface,” assures Thompson. Imagine to see a video of home reforms and be able to buy with a single click any tool that appears, even if it is in the background. It is the humid dream of every marketing giant. An invisible giant. Sometimes we forget YouTube. In fact, many analysts, including Thompson, who even He recognizes itThey have underestimated the platform for years. Most people prefer to consume entertainment in video and YouTube format have always been there, growing unstoppable and sometimes even invisible. The finish line, applied by Google. Thompson already He warned months ago about the potential of the AI ​​to convert each content pixel into advertising inventory, but then thought of a goal. The irony is that Google, who arrived late by offering the mass public tools of generative after Bard’s disastrous launchit is now who has arrived first with this technology. As assures Thompson, goal must still develop the necessary models and infrastructure; Google already has them working.

These are the seven most important novelties that you can try on your iPhone

by

For a few days, iOS 26 is now available for all compatible iPhone and arrives loaded with news. I’ve been using iOS 26 since yesterday And I’m going to tell you the seven most important functions you can configure As soon as you install it. Change the design of the icons From iOS 7 we did not see such a radical change in the design of the iPhone interface. Liquid Glass completely changes the entire systembut also introduces new designs for all the icons and widgets of the home screen. To be able to change it, simply click on an empty display area until the icons begin to “shake”, then click on ‘edit’ in the upper right corner and finally in ‘customize’. The four icon styles that we can use: by omission, dark, translucent and tired Apple offers us four options. We have the omission mode that are the colorful icons of a lifetime and the dark mode that puts them black background. The novelty is the translucent mode and the tinting modein which we can choose which tone they will have. I personally prefer the omission mode and it is the one I am using. The new ways make all apps of the same tones and cost them more to locate them, but as the saying goes “for tastes: colors.” Customize the lock screen The new elongated clock is the identity of iOS 26 The lock screen also becomes more customizable with iOS 26. To edit it you can do it directly by holding on the lock screen and then clicking on ‘Customize’. The highlight is that We can stretch the clock to occupy more screen. Of course, it can only be done with the first typography, the other three cannot be stretched. You can choose how long you want it to be and the thickness of typography. Notifications will adapt so that they do not cover the time. You can also use Space photos on the lock screenas long as the photo allows it (it works great with photos of people and pets). Within the customization of the lock screen you will see that a hexagonal shape appears. Pulse it and you will see how the subject “separates” from the bottom, causing the iPhone to move as if it were in 3D. Customize the new app photos iOS 18 brought a new photos with photos with A very risky designand who says risky says very uncomfortable. The app was less intuitive and cost a lot to get used to its interface. It seems that Apple has heard The complaints and With iOS 26 they bring us a much better organized app. The APP photos makes sense again. The new APP photos has two tabs, the photo library where all the photos in chronological order and collections are. This second tab has different sections such as albums, set collections, outstanding photos or memories. The best thing is that, if you go down to the end, You will see the option ‘Reordenar’ with which you can choose what you want it to appear above. For now, Apple does not let any of these sections hide, but if you click on the arrow You can fold them so that there is not so much visual noise. It ended up having to navigate between travel memories, outstanding photos and other suggestions to find the album you were looking for. Try the visual search When you make a screenshot you can do a visual search and talk to Chatgpt. Among the functions of Apple Intelligence that arrive with iOS 26, the most prominent is the visual search. To access it only You have to make a screenshot and select the visual search icon down to the right or, if you prefer, make a circle about what you want to look for, very much in the style of ‘Roda to search’ from Google. A page will open with results similar to what you have sought, for example in the case of the example of the images, I asked him to look for the mobile that appeared in the article and offered me many Wallapop results to buy the Xiaomi 15 ultra. You can also ask Chatgptwhich will respond taking into account the context of what appears on the screen. Make Siri answer calls for you If you activate the call filter, Siri will answer for you. The call filter is one of the great novelties of iOS 26 and promises to end the calls of unknown numbers. It is activated from adjustments – telephone and allows you to choose between the calls of unknown numbers so that it is Siri who responds. What he does is ask the interlocutor the reason for the call and It shows you a transcription of what has respondedso you choose whether to answer or not. There is also a more drastic option, which is that the iPhone will not sound when it calls us an unknown number. Apple’s solution is quite radical And you should keep in mind that you may lose some important call, for example of the doctor. I have not activated it for this reason, but They are fried with spam calls You may want to give you a chance. Use real -time translation It is another of the novelties that arrive with the new update. You can use it to translate a real -time conversation from the app translate. Simply select the languages ​​of the interlocutors and start talking by clicking on the microphone. The app will automatically translate what we say In text and we can also reproduce it. In addition, translation It can also be used in the messages app. If someone writes you a message in another language, click on it and select ‘Translate conversation’ to translate all messages automatically. Activate adaptive battery mode Finally a novelty that affects battery consumption. In addition to the low consumption mode that we already had, iOS 26 premieres an adaptive mode that You … Read more

Volkswagen presents the ID. Cross concept and the most important thing is not the car, it is the flying in its strategy

by

The automotive segment celebrates one of its big weeks. The Munich Motor Show, now renamed IAA Mobility, brings together these days to theThe manufacturers that present their novelties For the coming months, and one of them is a Volkswagen that has taken the appointment as a crucial event to rethink the future of its electric cars. Have already confirmed that They will stop using rare names for their EV And they have taken the opportunity to show their new SUV 100% electric: The ID. Cross concept. It will be ‘Made in Spain’ and a key piece to fight against the avalanche of Chinese cars. In addition, the buttons return. Change of concept. Something worth clarifying is the name. Id. Cross is like the electric version of the Volkswagen T-Cross, but that surname ‘Concept’ can mislead when indicating that it is a prototype. In this case it doesn’t seem like something like What Jaguar did a few months agosince the images that the brand has shared have a more street air than prototype. It is expected that the final version is similar to what they just showed. But the important thing is the name. VW wants to give a fly to some of its recent policies, the choice of the name being a sample that The experiments are over. The new pole will be the pole and this new SUV is an ID. (which identifies your electric family) with the surname ‘Cross’. The numbers are also over They can confuse more than anything else. SUV + EV = Win. About design, as our partners detail Motorpasionwe have a car very similar to the combustion T-Cross. It has 4.16 meters long, 1.83 wide and a height of 1.58 meters. The main trunk will be 450 liters, similar to the combustion version, but add another 25 liters in a small compartment in the front. That it is a SUV, although with a compact size, it is a very interesting strategy in terms of potential autonomy. VW has not given details about its capacity, but it has indicated that it will have 420 km approved WLTP and a 175 km/h tip. It will be based on the MEB platform and will be built in the same money as its cousin, the Skoda Epiq: that of Landaben In Pamplona. “Id. Cross shows that we offer again, finally, the correct name. With this new generation of VE, we now meet our promises” – Thomas Schäfer, CEO of Volkswagen This combination of Urban SUV Together with EV, he promises to be one of the golden egg chickens for manufacturers, since it is A very demanded format And, in addition, the extra space in front of a compact or utilitarian allows to install a larger battery, reducing the time that passes in the plug and expanding its versatility. It wasn’t so difficult Back to the button. Apart from the outside, VW has shown images of the interior of this ‘concept of preerie’. Very diaphanous, soft colors, different materials and completely folding seats to maximize the load. We will see how this translates into the final model, but there are two elements that are very important. On the one hand, the screens are not missing. We have two: one behind the 11 -inch steering wheel with the digital instruments and another 13 -inch central for the entertainment info system. But something that is obvious and that, curiously, VW does not detail in its release It is the return of the buttons. Companies have launched Tactile controls on screenssomething that has been eating the physical buttons Even in brands that seemed to star in the ‘resistance’ To this trend. The problem of the screens is that they can fail and are less intuitive than a button. VW minimized these physical controls by installing digital buttons that gave several headaches to the brand, and After the alluvion of criticismcomes the flying that the company itself already warned with that “It is not a mobile, it is a car“ In these images, however conceptual they are, we see that there are a lot of buttons both in the steering wheel and under the central screen, as well as a joystick that seems to control for that infotainment screen. Declaration of intentions looking at China. Thus, and as much as it is not a final car (although it will be necessary to see how much the unit of this of Preserie moves, the id. Cross confirms the change of course of a brand like VW: the buttons return, the family names return. And those decisions are consolidated with a model that will be vital for the company for a very simple reason: the competition in this sector will be fierce. In the same Mobility, Stellantis has received with open arms A ship arrived from China up to LEAPMOTOR B10. Although the Chinese brands are consolidating in the West with All types of motorizationsthey continue to have great interest in electricity for those who control the world battery market, and this B10 is the result of the Agreements between Stellantis and Leapmotor To assault the 100% electric compact terrain in which the ID wants to compete. Coss. In fact, the VW model is somewhat more compact with an autonomy similar to that of B10. The last of the concepts. The competition is served with rivals such as the Renault Scénic E-Techhe Byd Atto 3 or the MG ZS EVbut to see this new id. Cross we will have to wait. In its presentation, the brand has confirmed that the ID will first arrive. Polo, then the id. Polo GTI and later, but in 2026, the definitive version of this ID. Cross. On the price they have not said anything, but taking into account the segment in which they want to compete, it is expected to be positioned in the 30,000 euros window. At the moment, the IAA Mobility has served to see a clear response from the German brand to two controversies in … Read more

Our brain also “draws the garbage.” And it is one of the reasons why sleep is so important

by

We have known for a long time that sleep is more than rest, it is a vital need such as eating or breathing. Lack of sleep can have devastating consequences on our physical state, but also on our mental state. The big question for many scientists is why, a question that we have not yet answered at all, but in whose resolution we have advanced significantly. Sleep and dementia. A line of research that in recent years has gained importance has been the one that studies the role of the glinphathic system in the relationship between our dream and the appearance of dementia. The key would be in the “cleaning” work that this system exerts in our brain. The glinphathic system. The glinphathic system can be seen in certain contexts such as a cerebral analogue of the Lymphatic system. This forgotten anatomical system exercises different tasks in our body, being one of them to “take out the garbage”, clean the accumulation of waste generated by cells and eliminate harmful substances that may be present in our tissues. The lymphatic system does not extend through our brain, but someone must perform this important task in the central nervous system. A few years ago we began to understand who and how. The problem is that we have not yet managed to find out the most relevant aspects of the call GLINFATIC SYSTEM. Cleaning the plates. This cleaning work could be linked to the appearance of diseases such as Alzheimer’s. In A recent article in The conversationa group of researchers from the Macquarie University formed by Julia Chapman, Camilla Hoyos and Craig Phillips, explained this relationship. This hypothesis is based on the role they play in the appearance of the disorder Beta-amyloid proteins (Aβ). Over time these proteins tend to accumulate in our brain and, if they are not refined, they form plates that hinder the proper neurological functioning, damaging the brain and giving rise to the appearance of the disease. Night work The hypothesis that links sleep and Alzheimer’s way of the glinphathic system is also based on the idea that it is during the dream that the system takes the opportunity to clean impurities and toxins. However, the doubts about what the dream is what this relationship unleashes. As Chapman, Hoyos and Phillips stand out, studies sometimes seem to contradict, for example when measuring if the Aβ levels we find in the brain liquid are greater during sleep or during vigil. From mice to people. One of the problems we find in this line of research is that much of what we know we know it thanks to studies in micewhile the analysis with humans are limited. However, some studies have managed to approach the problem from human biology. An example cited by the team is A study Posted in 2018 in the magazine Proceedings of the National Academy of Sciences (Pnas). In it the team observed how a simple night of sleep deprivation could cause Aβ levels to increase significantly in the hippocampus. The study therefore reinforces the theory that the dream is closely linked to the probability of dementia. The risks of insomnia. The 2018 study was conducted in healthy people who experienced a night of sleep deprivation. So what about people who have insomnia or similar problems? This issue is different and requires a separate study. According to Macquarie’s team, some analysis carried out with people with insomnia and sleep apneas (interruptions caused by breathing problems) have associated these types of problems with a higher risk of dementia or with lower levels of Aβ. This again seems to support the thesis of a relationship between sleep and dementia mediated by this “cleaning system.” Another relevant issue is how sleeping pills influence, if it is at sleeping facilitate the functioning of the glinphathic system or if on the contrary the effect of these does not facilitate their night activity. A study Made in mice and published this year in the magazine Cell points to the second possibility since these compounds They did not activate the appearance of norepinephrinea compound that seems to perform an important rum in this “drain” function of toxins and other harmful compounds for the brain.
