We have before us the great European technological strut

by

The Dutch company ASML will become the largest shareholder of the French artificial intelligence company, Mistral. According to the data, it will invest 1.3 billion of the 1.7 billion that Mistral will raise in an imminent round of financing. Although both companies are great protagonists From the European technological panorama, the alliance is strange. And yet, promising. Mistral becomes greater. The Parisian company He has raised more than 1,000 million dollars since it was created in 2023, and is close to closing that new and important financing round which will make its valuation approach 12,000 million dollars. It will thus become one of the most important technological companies in Europe. Semiconductors + ia. ASML It is the company in charge of manufacturing the most advanced lithography teams around the world and then selling them to companies like TSMC or Intel. Each of its photolithography systems Uve It costs about 180 million dollars And they are crucial and then produce the most advanced chips in the market. That ASML has entered fully into Mistral’s shareholders is surprising, especially because although both are technological companies, their direct relationship seems weak. So, what is the reason for this movement? Europe is a little more sovereign. It has been a long time since Mistral focuses your business In the European business market, where it precisely presumes to offer that digital sovereignty with which EU countries can be a bit more independent of US or Chinese companies. That ASML has opted so strong for Mistral is a unique declaration of intentions to significantly reinforce Europe in the technological panorama. Is it for better semiconductors? At the operational level, ASML may also have had reasons to take advantage of Mistral technology to improve their own photolithography machines. In fact, TSMC is including AI technology in its manufacturing plants thank you to its alliance with Nvidia. Sources close to the company reveal that ASML could benefit from the misstal experience in data analytics to improve its performance and develop new products. A promising alliance. The relationship between both companies is as we say weak, but we are facing an alliance that from the point of view of the European technological panorama can be a notable first step for Europe to have at least options to have an alternative to the supremacy of China and the US in this segment. Open to acquisitions. As they point out In SiftedMistral published a job offer last month – now disappeared from its employment portal – in which someone was sought in strategic operations. The mission of the candidate was to “search and advise in future acquisitions”. Nearby sources indicate that there is at least a potential objective for an customs, which will try to add small businesses that expand their product offer. A much more open future for Mistral. The Mistral AI models, although remarkable, do not usually compete for you to you with the great foundational models of OpenAi, Google or Anthropic. That put the company in a delicate situation Looking ahead, especially for the few resources with which he competed in front of his rivals. This financing round makes things much clearer to the Gala company and seems to guarantee its future, at least in the short and medium term.

The US already proves its new “Airplane of the Last Judgment”. His role is to keep the command chain even in a nuclear scenario

by

The most resilient aircraft in the United States has just written a new chapter in a story that started half a century ago. The Air Force and Sierra Nevada Corporation They have launched the First flight tests of E-4C SAOC, direct successor of the E-4B Nightwatchthe family of “Final Judgment” that guarantees the continuity of command even in the worst scenario. Recently, a giant based on a Boeing 747-8he first took off from Dayton, Ohio, opening a trial campaign that will last in the coming months and that opens the transition to a more modern fleet. With this step, the North American country begins to replace flying bunkers that approach at the end of its useful life. It is not a new concept: we talk about the evolution of a system that combines government continuity, safe communications and nuclear deterrence. The SAOC program, with a contract of More than 13,000 million dollars Awarded in 2024, it is a change of method in the Pentagon: for the first time, the original manufacturer of 747 does not lead the integration and responsibility falls to a company specialized in large conversions, which has brought together first level partners to build the most advanced command plane of its time. That inaugural flight is the first step of a decade of work to deliver a platform capable of continuing to operate when everything else fails. A new chapter for the most strategic plane in the United States The SAOC (acronym for surviving Airborne Operations Center) is the most ambitious Air Force project to reinforce its network of Nuclear control, control and communications. Its mission is clear: to ensure that, although the strategic centers on land remain unused, the country’s leadership can coordinate a military response and Maintain control of the armed forces from the air. It is no accident that these aircraft are known as “final judgment planes”: they are designed to be the last resort in a scenario where everything collapses, operating as a true flying pentagon. The first generation of this platform, the E-4B Nightwatch, entered service in the seventies on the basis of a Boeing 747-200. Currently, the United States maintains four units Active, all deployed in the Offutt Air Base, Nebraska. Despite their robustness, the passage of time passes by an invoice: each plane has decades in service, the spare parts are increasingly difficult to get and Its availability is barely 55%. Keeping these giants operational is a expensive task, and the Air Force plans to remove them at the beginning of the next decade. The renewal is already underway. Sierra Nevada has received four of the five Boeing 747-8i acquired from Korean Air, and in them are applied deep modifications. Dayton, Ohio, and Wichita, Kansas They concentrate the Conversion and test operationswhich will be extended at least until 2026. This staggered plan will allow the new aircraft to enter into service while the E-4B begin to withdraw, always maintaining an operational nucleus that ensures the continuity of government. A E-4B Nightwatch currently operational The technological jump is evident. The 747-8 is the last large commercial aircraft of four engines made in the United States, with greater fuel capacity, more efficient engines and a broader fuselage than its predecessor. These characteristics make it the ideal base for an airplane that needs to sustain prolonged operations with refreshing in flight. The 747-8 cell also provides growth margin to integrate advanced communications, reinforced armor and redundant systems, all designed to survive electromagnetic pulses or cyber attacks. E-4B Nightwatch Decades of antiquity in flight At an industrial level, the program also makes a difference. Although Boeing remains the original 747 manufacturer and provides structural support, this time does not lead the project: the Air Force opted for an open data model to ensure that the government owns the design and can modify it in the future without depending exclusively on the OEM. Boeing It was out of the bid in 2023 after disagreements on the terms of the contract and data rights, which opened the door to Sierra Nevada Corporation as the main contractor. The company, known for its high complexity projects, has formed a team with giants like Lockheed Martin, Collins Aerospace and Rolls-Royce to create an unprecedented platform in the military. His role in recent history reinforces the need for this investment. E-4B have participated in critical events: from government continuity exercises to emergencies such as September 11, 2001 attackswhen at least one of these aircraft took off to provide safe communications in the middle of chaos. These aircraft have routinely accompanied the Secretary of Defense on International Travel, remain on alert during presidential speeches to Congress and act as a support network when national security protocols are launched. In the popular imaginary they appear little, but their mere existence is part of the United States deterrence strategy. The E-4C SAOC is, more than an update, a long-term bet. The contract signed with Sierra Nevada is It extends until 2036which reflects the magnitude of the technical challenge and the necessary time to complete the conversion of the aircraft, certify and deploy them fully. With this plan, the United States ensures that the most critical piece of its system of Nuclear control and control It will remain in force for decades. Although many details, such as the exact equipment of antennas and systems, are still classified, what is already underway is a clear message: the ability to direct the country in a global crisis depends on a strategic investment that seeks to always have a command center in the air.

The new aesthetic luxury of “liquid surgery” that promises what the Botox no longer sells

by

In the new economy of the “invisible luxury”, the object of desire no longer hangs from the arm: it melts with the skin. Instead of great transformations, the aspiration is that “it is not noticed.” A lifting without scars, a brightness that looks like a repair dream. In that league the newly baptized “liquid surgery” plays: four -digit facials that promise a Botox effect without needles or rigidity. A new trend. After the rejuvenated reappearance of Lindsay Lohan, a reporter from The Times He went to the most exclusive spa by Beverly Hills to test the “MBR Best and Ultimate Liquid Surgery”, a 995 -dollar protocol. The session includes cleaning, toning, hyaluronic acid masks and, above all, the application of a star serum: 1,784 pounds the 50 ml bottle, sold as “viper venom imitator” to achieve a “more subtle” botulin toxin effect. The journalist described a “striking” difference after applying the product in half face and collected that the usual clientele includes local elites and celebrities that repeat monthly and complement at home. The text itself points out that the term “liquid surgery” was coined by a German marketing department: there is no scalpel, but a high -cost cosmetic ritual with immediate results. The spa presents it as the “less invasive” route towards the good face effect that was previously associated with visible injectables. Aesthetic luxury changes the skin. The turn responds to a broader trend: undetectable results. As we have detailed in Xatakathe deep flat lifting – which repositions muscles and ligaments in block to avoid rigidity – has become the standard among star surgeons. The effects last between 10 and 15 years, but prices easily exceed six figures. Given this situation, Botox has lost part of the story. In a report for Women’s Health They have described as Jennifer Aniston He has recognized that he tried the injections, but abandoned them for considering them “ridiculous” in excess. Instead, combine facials, lasers and radiofrequency (Themage) with a healthy lifestyle. The narrative now relies on bioestimulators: polynucleotides derived from salmon DNA (PDRN) that promise cellular hydration and regeneration, or exosomes, small vesicles that act as regenerative “messengers”. He Glow discreet becomes symbolic capital. Towards combined protocols. The immediate future points to repeatable treatments, expensive and continuous maintenance, which mixes apparatus (laser, radiofrequency) and cosmetic biology (polynucleotides, exosomes). That is today the “toolbox” that celebrities present as an alternative to click or go through an operating room with public visibility. On the cusp, the elite scalpel continues to mark status; At the base, four -digit facials sell the “invisible effect” in cabin format. This is how the term coined as “liquid surgery” fits at that intersection. The problems that are coming. The boom of “liquid surgery” and other less invasive treatments drag shadows that should look straight ahead: from the regulatory vacuum to unequal aesthetic pressure. On the one hand, The Newbeauty Portal Document The case of Victoria Nelsona client that denounced burns and scars after a “high -power” peeling and microneedling years performed, allegedly, out of the legal reach of a aestheticist in California. Dermatologists consulted recalled that procedures such as medical peels, microneedling, lasers or injections should be carried out in clinical environments and under medical supervision. A peeling, they underlined, is not a ritual of beauty but a “controlled chemical burn” that, if it runs badly, can leave irreversible sequelae. The case illustrates a hole between marketing, licenses and security. On the other hand, in other types of treatments science does not support a promise. Polynucleotides –extracted from salmon DNA and increasingly present in elite clinics– They have biological base and even a previous medical use in wounds and burns. Side effects, when injected, are usually mild (bruises, swelling), but robust studies are missing that support their long -term benefits. It also happens with exosomes that it is still consolidating in the scientific field and with collagen supplements, where the benefits are modest or contradictory and many studies have been financed by the brands themselves. There is an even broader background. The aesthetic pressure is not limited to the cabin of a spa. The cultural narrative has oscillated from Body Positive to ultra -launching standardsamplified by Fashionable thinning drug and Digital filters that multiply impossible expectations. In this field, scrutiny is deeply unequal. They carry the demand to stay young and with a double penalty: both those who are operated and those who decide not to do so are criticized. Sarah Jessica Parker has been insulted for showing wrinkles, while Pamela Anderson was criticized for exhibiting her naturalness without makeup. Men, on the other hand, usually enjoy indulgence: names such as Brad Pitt, Tom Cruise or Bradley Cooper have starred in speculation about touch -ups, but rarely face the same public trial. Even the data shows the gap: As we have pointed out in XatakaLiftings in men grew by 26 % between 2022 and 2024, but the media account presented them as a simple “set -up”, not as an “aesthetic obsession.” The result: eternal youth remains a female demand and an optional option for them. An eternal youth with conditions. The snake venom facial in Beverly Hills is more than an aesthetic whim. Summarizes a global trend: displacement towards less invasive procedures, more expensive and with an aura of exclusivity. An eternal youth reserved for those who can pay it, while the rest of society consumes supplements, collagen powder and digital filters as substitutes. The question, however, is still open: are these advances a real scientific revolution or a marketing mirage? Maybe how did The Times the chronicler When leaving the spa, the eternal youth does exist, but it costs the same as thirty beers in an airport. And, above all, it is still a luxury with class, gender and power more visible gender than any wrinkle.

I’ve been using Yi security cameras for years. It was delighted until the app became an advertising hell

by

More than five years ago I bought my first Security Chamber To monitor my cat when he got sick. It was YI brand and it worked great; He looked good, had movement alerts and could speak through the mic. With the passage of time I had more cats and I bought two more cameras of the same brand to cover the rest of the house. The problem is that The APP Yi Home has added advertising in its app. How much? All. It is not an exaggeration I was traveling recently and I entered Yi Home’s app to look through the cameras. I don’t lie if I say that More than once I have made me want to launch the mobile. On the main screen there are already a few ads spread there, but that is not the worst. Some of the ads that appear when I open the app or when I try to see one of the cameras. The worst are the Full screen ads. They cannot be skipped until they pass a few seconds, the button to close them is tiny and sometimes it does not work, causing it to end in the App Store, or wherever the announcement in question link. So every time I open the app. But the thing is not there, when entering each camera, advertisements also leave full screen. When you finally manage to see a camera, a banner comes out that covers the controls to be able to move it *Chef’s Kiss*. Few apps I remember that they have bombarded me both with advertising and Yi Home, although it is not the only one. A current example is Capcut, the Tiktok videos editing app. Every time I open the app, I get a full screen advertisement, but it is also that if you leave a moment and enter again, another appears. Not to mention that The entire app is a mines field with ‘Pro’ functions And they don’t stop insisting to join. Pay or suffer Yi Home has never been a super clean app. I already had some Banner type ads and has always shown me pop-ups to join the payment plan. The thing now has no name. In addition to full-screen advertising, those pop-ups continue to come out and remind me that, If I pay, advertising will disappear. On top with picn. The summum of despair. (The controls can be relocated, but was there no other place?) The cheapest payment plan if you have several cameras costs 79.99 euros a year. It seems expensive, but I think that although it would cost a tenth, I wouldn’t pay either. The thing about this app is A manual of how to lose customers. At least I know I am not the only user discontent, In Tustpilot is full of negative reviews on the same subject and in This Reddit thread There are also several angry users. In the same thread they also comment on several ways to eliminate ads such as installing previous versions of the app or configure a DNS with Ad-Block. In my case I take another way to eliminate ads. I change my chambers I had been wanting to buy a while Another 360 camera And obviously I was not going to buy another of the same brand with the problems I was having with advertising in the app. One of those days when I almost crashed my mobile, gave me to get into Amazon to see other cameras and make the decision. TP Link Tapo C210 After reading a few reviews and making sure that his app did not seem like an online casino, I opted for the Top-Link tapo. I found a Offer pack with two cameras 360 And I bought it. When I set them up, some notifications came out within the app to go to the Premium version, but I have been using it for a week and they have not reappeared. Come on, what was Yi Home’s app a long ago and that It should be normal in an app of a security camera.

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

by

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

Latin America and Africa are a juicy caramel for car manufacturers. And the Chinese industry is already moving file

by

The Chinese automotive industry has launched to the ambitious adventure to conquer the world. Yes last year We were talking about tariffs And both the United States and Europe looking for trying stop the expansion of the Chinese electric carnow we talk about huge ships from the main companies bringing their cars. But China Not only is your eye on Europe. It is already moving towards Africa and Latin America. Restrictions. Apart from bringing their cars to our borders, Chinese companies are moving forms for expand your dealer network in Europeas well as They operate their own factories. To ‘skip’ tariffs and restrictions, instead of manufacturing cars in the usual way, they do so by removal kits and put. But it is evident that these tariffs imposed on the electric car have been the trigger for the export to the West to cover other territories. In fact, brands such as ByD came to rethink their international strategy in some markets, and those alternative destinations outside the traditional axis are those that have lower commercial protection and greater growth potential. Africa (the north, especially) and some Latin American countries stand out for their lower customs obstacles and local policies that encourage the industry.

To the question of whether ultraprocessed foods are as bad as they have told us, science still has no clear answer

by

When going to the supermarket it is easily being surrounded by fried potato bags with different flavors, cookies, soft drinks, frozen pizzas or chicken nuggets that are part of our shopping basket. They are the so -called ultraprocessed foods (UPF), products that have gone through multiple industrial phases and often contain ingredients that are not found in house kitchen, such as corn syrup or hydrogenated oils. A debate for a long time. The alarm was given in the early 2000s Brazilian researcher Carlos Monteiro. While trying to decipher The increase in obesity and type 2 diabetes in your countrydiscovered something paradoxical: people bought less sugar and salt than before. The explanation was in the Super cart: they had replaced the basic ingredients with precooked and ready products to consume that they were loaded with these same foods. Growing evidence. From that moment on, scientists began to put the batteries to try to demonstrate whether there was a link between the high consumption of these products with health problems, because they had increased at a vertiginous pace. From there, dozens of studies associate high diets in ultraprocessed with higher risk of obesity, cardiovascular diseases, type 2 diabetes, cancer and even depression and anxiety. A large -scale study with more than 110,000 adults in the United States found that those with the highest consumption of ultraprocessing were 4% more likely to die for any cause during the monitoring period. Variations between countries. The same amount of ultraprocessing in all countries is not consumed of our area. While in the United States and the United Kingdom Almost 60% of calories come from ultraprocessed In Spain the figure is around 26-30%. Despite being in the lower part of the table compared to Anglo -Saxon countries, recent studies, such as the one published by The BMJ, alert that the strongest evidence associates ultraprocessed exposure with cardiometabolic health problems, metal disorders and mortality in general. Is El Villano processing? Despite the overwhelming correlations, not the entire scientific community agrees to demonize the ultra -processed as a category. The main argument of skeptics is that The group is too broad and heterogeneous. In this way, the question is raised if it is logical to put some donuts, fried potatoes and a supermarket yogurt in the same bag. Some researchers wonder if the association with poor health is not due, simply, that these products are usually rich in fat, sugar and salt, and poor in fiber and vitamins. However, several studies have tried to clear this unknown. A clinical trial of the University College of London He compared two dietsone based on minimally processed foods and another with ultraprocessed, but both with identical levels of key nutrients such as proteins, fats, fiber and sugar. Surprisingly, participants lost twice the weight with the minimally processed food diet. This suggests that nutritional composition is not everything. Beyond calories. A breaker essay led by physiologist Kevin Hall in the National Institutes of Health of the United States (NIH) locked -literally -20 adults In a research center and gave them freedom to eat everything they wanted. For two weeks they followed an ultraprocess diet, and two others an unprocessed diet. The results were revealing: with the ultraprocessed diet the participants consumed 500 calories more a day and won almost a kilo. Hall and others investigations suggest that energy density and food texture are key. Many ultraprocess, having less water, concentrate more calories in less grams. In addition, its texture is often softer, which leads us to eat faster. By eating faster, our brain does not have time to register satiety signals, which facilitates excess caloric consumption. Ciaran Forde, researcher at the University of Wageningen, demonstrated that people ate much less when they were presented with hard texture foods (such as gofre -type fries) compared to soft texture foods (such as potato puree), regardless of whether they were ultra -processed or not. “What we saw was that the speed of eating and the texture properties of the meals boost consumption, not the degree of processing,” says Forde. What do we do then? Although the debate on the definition and the exact mechanisms continues, the general trend is clear: a diet with a high percentage of ultraprocesses is consistently associated with worse health results. The solution, however, does not seem to be a total prohibition. Kevin Hall himself, one of the most critical researchers, admits which consumes salad salads and dressings bought in the store. His advice for friends and colleagues is pragmatic: “Eat more vegetables without starch, legumes, fruits, integral grains and limits the intake of added sugars, sodium and saturated fats. Choose the ultra -processed that help you to be convenient and affordable, and avoid those that make it difficult.” Images | Alan Alves Xataka | Making rice of more is no longer a mistake: cooling it and reheating it can reduce your calories according to some nutritionists

There will be only one young man for every three professionals who retire

by

Spain faces an unprecedented challenge with respect to generational relay of the current active population due to demographic aging. According to a recent one Study of the Observatory of the Professional Training of Caixabank Duiza and Orkestra Basque Institute of Competitiveness, in Spain there is a deficit of almost 3.5 million people under 30 years in the employed population to compensate for the weight of the population over 50 years of age than He will retire In the coming years. “There is a true demographic fire, only that it is not unforeseen, we have seen it on and extend,” declares to The avant -garde Mónica Mosa, researcher and co -author of the study. This mismatch among young people under 30 and over 50 years old It has doubled In the last decade, putting at risk the sustainability of many companies and economic activities for shortage qualified labor. Demographic differences in the working population. As the report points out, for each young person under 30 there are three workers over 50. This imbalance will make, for example, in a decade this proportion He moves To the price for retirement benefits, where a worker would support the benefits of several pensioners, increasing pressure on the pension system. In communities such as Asturias, for every 100 young people under 30 there are 257 over 65 years old, while in Castilla y León and Galicia this proportion exceeds 220 greater than 65 per 100 young people. These regions, characterized by being rural and with a High depopulation ratethey have added difficulties to attract and retain young labor in fundamental professions such as agriculture, livestock or forest agents, pillars of their local economy. The low birth rate. The main trigger for this situation is decline Birth rate in Spainwhich in the last ten years has dropped by 27%. The average number of children per woman is well below the necessary to maintain the population, which has gone from 9.11 born by a thousand inhabitants in 2013 to 6.61 births per thousand inhabitants in 2023. However, this rate varies considerably depending on the origin of the families, varying from the 8.30 births per thousand inhabitants of Spanish mothers at 16.05 of foreign mothers. Likewise, the study includes that the number of children per woman has also dropped from 1.27 in 2013 to 1.12 in 2023, being equally lower among Spanish women (1.09 children) than among foreign women (1.28 children). These last figures are a clear risk to the sustainability of the generational relief in the workplace, taking into account that at least 2.1 children per woman would be necessary to guarantee it. The impact goes by sectors. The shortage of young people especially affects sectors with traditional and technical trades such as electricity, plumbing, carpentry, manufacturing industry, construction or repair of vehicles. In this group of artisans and qualified workers record a deficit of around 500,000 young people to occupy the vacant positions left by the workers who retire in the next decade. In sectors such as public administration, difference is even more marked: For every 100 officials under 30 there are 690 over 50 years. This is one of the reasons why the Public Administration has stepped on the accelerator in the call for oppositions in which record figures have been reached. In the opposite pole, sectors linked to leisure and culture, Information and communications and hospitality are not affected by this mismatch in the generational relief since they attract a greater number of young people, contrasting with the low attraction of young professionals in industrial and administrative activities. Labor scarcity will impact the economy. The regions with the greatest presence of the most affected professional sectors such as Andalusia (Agriculture and Livestock) Catalonia and Madrid (industrial sectors), show the largest deficit figures of professionals in absolute numbers approaching (and even exceeding) close to half a million people. These communities stand out as the main focuses where the lack of generational relief will be more critical for the local and national economy since its active population percentage with respect to Spain’s total is also greater. Professional training as a key to relay. The report indicates The importance of professional training (FP) as a fundamental solution To face this deficit of new professionals in industrial sectors. According to their authors, the greatest imbalances are seen in the average grade, where there is a lower attraction of young people with respect to those of higher degree. In general terms, there is a lower generational gap among people occupied with FP. This is due to the ease of access to the labor market of young people studying professional training. However, the different branches of professional training must keep attracting young people during the next decades to balance the current deficit. On the other hand, the lack of young people trained in the care sector, whose growth is linked to demographic aging, and the talent migration of the abroad health sector complicate the balance in the generational relief. The report underlines the importance of achieving “young people stay in the territory” and connect their training with the business fabric to ensure effective relief.

More than 200,000 books for 11 euros a year. It is ‘The Free Books Club’ of Valencia, a paradise for printed paper devotees

by

In a city like Valencia, not precisely lacking second -hand librariesa project has been born that goes beyond the mere business with volumes that have already lived one or more readings. It’s about ‘The Free Books Club ‘, a mixture of bookstore, paper trace, social club and NGOs Bibliophile that, in exchange for a minimum fee, allows its partners to take all the books they want. Its responsible is Rafael Soriano, who transmits an enthusiasm for reading perfectly In line with the philosophy of the premises: “All books are jewelry, some need a little mime and that is the goal of the club: save the books, pass them from good hands to others and in that way, among all, to have an immense library of people who want to continue keeping the books.” All books They deserve be read (As Rafael says, “a book can be a brick, but if you find a page, a paragraph, a text that tells you something, is already a good book”) and therefore preserved. That is why the Free Books Club ‘has an affordable partner share, 11 euros a year, which allows you to take all the books that are desired (To donate it is not even necessary to be a partner), return them or keep them if desired. The intention of the club is that no book is discarded, and of course, that leads to problems. The main one is that Rafael stopped counting the specimens in the premises when he reached 200,000, and the lack of space has forced him to stop classifying, archiving, listing and even restore those volumes they need. In the original place there are no more volumes, which has led them to resort to “partners who have some space at home, a garage, a small warehouse. When someone requests a large rescue, let’s say ten, twelve, fourteen boxes of books, in the premises of Valencia they do not fit.” The project has thus became a completely collaborative idea: the website centralizes the calls for help in search of space, and They estimate that right now they will be around 300,000 “saved” booksas Rafael likes to say. There are future and expansion plans although at the moment the relief comes from projects as another open club in Padrón (A Coruña) with similar operation. An agreement with emails has also been reached so that the partners can exchange books directly without going through the Valencia premises, again with the website as a meeting point. Although Rafael’s ambition goes further, and would like to see premises like his in other provinces, and “that the partners can take a book in Valencia, leave it in Cáceres, take one in Cáceres and leave it in Barcelona.” Computer to Guardian de Books Rafael Soriano started his career as a computer programmer: “I started computer studies before there were computer faculties. In the year 85 I started from 88 I dedicated myself to programming for different clients. In the end the fort of my programming was the management of bars and restaurants. “Later he made the leap to the other side of the screen:” For having met the sector, I was as manager of a bar-restaurant for a year, with thirty-so many employees on the beach. “ After dedicating almost ten years he transferred him and stayed “a little in limbo: I am not yet retired, but I don’t want to be at home, even if I have some resources to endure.” And in this way the club was born: “A little like Hobby, a little as a refuge.” And near the sea, “because I like to swim, see dawn swimming.” A completely born project of devotion to the printed page and has set in something more than a bookstore: A home for old books that serves as a transit in search of new houses. Or as Rafael says, “it is an alchemy workshop, that is, everything that is there is paper, it is an piled paper, but in the right hands it becomes gold.” In Xataka | Before he died, this man left a list of everything he had read in his life: 3,599 books of all kinds that you can now consult

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.
