Space station astronauts have made sushi. In Japan they would open a war advice, but it is fantastic

by

Sushi and ramen are to Japan what the potato tortilla –With onion– Or Paella to Spain: a sign of cultural identity. They have more complex origins than we think: while ramen derives from Chinese cuisine, Sushi was born as a conservation technique before transforming into a gastronomic icon. To such an extent that to International Space Station Astronauts He has given them to prepare Sushi with what they had at their disposal. It has come out regular, but at the same time it is fantastic. Space food It is not a secret that space food You must have very specific characteristics. It is mostly lyophilized And it is thermosellated. Before consumption, the one that is not ready to consume, must be rehydrated and any food and ingredient that enters the season You must meet a series of both security and cleaning requirements. Conservation is also very important for obvious reasons And, although we can think that it is not good, The problem is usually astronauts. When cooking (among many quotes that cook), an ingredient as important as the food and condiments of the station is the double -sided tape. In numerous videos We have seen how ingredient boats such as honey or simple scissors are glued with that tape to the station surfaces. Sushi at the space station. Occasionally, one of the US members decides to surprise his companions cooking something out of the menuand Jonny Kim’s attempt has been one of the last examples. NASA American and Astronaut, hung A few weeks ago a photo in which a tray could be seen with an attempt at Sushi. To do this, they used precooked rice, fish, spam (A canned meat mark) and a touch of GOCHUJANG (A spicy paste based on rice and chili) and Wasabi. The humidity kept the ingredients glued, but for the tray and the rest of the elements, they used the aforementioned tape. Nostalgia. It is not the most appetizing sushi in the universe and, surely, Japan would have some questions for the architects of this culinary crime, but there is a great “but”: as on earth, this space sushi served for one thing: unite the members of the station. Up, despite fellowship, loneliness must be quite present and one of the astronauts commented that he missed the sushi. That gave them an idea: see what they had in their personal provisions to see if they could elaborate something similar. The result is obvious (rice with things on top), but the important thing is that “the result was a great meal,” as Kim points out, and served to foster that feeling of companionship and reduce, a little even if it is, that nostalgia. Nori algae. In X, someone He pointed out What would have been great to use Nori algae To wrap the sushi, but that he understood that it should be difficult to need a dehydrated version of it and that it would not be nice to have algae scales floating around. Kim replied that, in fact, they have Nori, but it is an ingredient that is part of the space orders that, with a limit, can do. And that he had run out of the ingredient. On the problem of the scales, everything is designed: “The crumbs accumulate in the air entry filters, which are aspired every week.” It is not the first time. It is a beautiful gesture, but it is not the first time that sushi is made at the station. It was not a photo, but a complete video that the Japanese astronaut Soichi Noguchi put on the chef’s hat for prepare A somewhat more “traditional” sushi with tuna, Nori and frozen scallops that had risen on board that intention. The reason for that elaboration was the same as that of this summer: surprise his teammates, take care of those ties and make the stay to thousands of kilometers of his homes is somewhat more cheerful. Also One way that missions are more bearable. In Xataka | Until the 90s nobody in Japan ate sushi with raw salmon. Until a marketing campaign changed everything

We knew that coffee was good for health, but now we have discovered that it is a great ally of our microbiota

by

For years, coffee has not been too well considered. It depends on the place and the historical momentbut the culprit was not so much coffee itself … as caffeine. Although the evidence has managed to deny them, there is still A lot of myths about caffeine and its effects. But something that is also making clear research is beneficial effect of coffee on the body. It depends on the type of tan, of course. And one of the studies More recent links coffee with the intestinal microbiota. Directly, it favors the Bacteria growth in our body. And it is something that fulfills a vital function. The community Microbial of coffee. As we say, different studies on coffee allow you to have discovered your beneficial effects on cardiovascular diseasesthe diabetes or your Effect on the kidneys. In parallel, a relationship between coffee intake had been observed with the increase of certain intestinal bacteria, but the studies were on a small scale. Now, in Nature Microbiology he has Posted a study in which the genomic sequence of the intestinal microorganisms of more than 22,000 people in the United Kingdom and the United States was investigated. They have discovered that coffee drinkers had a different microbiota, with intestinal bacteria such as Lawsonibacter asaccharolyticus Eight times more abundant in the microbiota of coffee drinkers than in those who do not ingest this food. And what does that imply. It is not limited to that bacteria, since increases in irmicutes, actinobacteria, actinobacteria were also observed, PREVETELLA, Faecalibacterium and Bifidobacterium, All of them linked to beneficial metabolic effects, such as greater production of short chain fatty acids. What this means is that, thanks to its polyphenols and the soluble fiber it contains, coffee produces some Prebiotic effects that have a direct influence on beneficial bacterial growth. Before I said that it is something that fulfills a vital function, and in this case it is not an exaggeration. Intestinal microbiome bacteria They fulfill functions such as facilitating digestion, strengthening the immune system, regulating inflammation or protecting against pathogens and diseases. Very direct effects of this includes the production of vitamins and enzymes that are not obtained from food, facilitating Digestion of compounds as fiber and starch or Immune system regulation to distinguish between harmful and benign organisms. Four cups. Tim Spector is one of the experts who has supervised the article and, as my colleagues from Straight to the palatethe amount of optimal coffee would be between two and four cups a day. It all depends on the organism of each one and tolerance, but something interesting is that we not only obtain those benefits for the microbiota, but also a a large amount of fiber. Specifically, 1.5 grams of fiber for each cup of Filtrated coffee (There are many ways to prepare it, but filtered or infused is one of those that allows to extract more nutrients), and it is an amount similar to what would be obtained when eating a tangerine And the caffeine, what. And this of the tolerance that each one has to coffee is important because there is a “Limit” in the amount of caffeine That we can take up to be in the healthy segment, but it depends a lot on each person. The good thing is that these positive effects on microbiota have been reported both in the ‘normal’ coffee and in the decaffeinated. If milk is addedIn addition, the amount of polyphenols may slightly decrease, but the balance is still positive. What should not be added is sugarsince there we would be doing more bad than good. But if decaffeinated coffee is consumed, you should have an eye on how the process has been performed. Not all decaffeinated coffees are the same because there are several ways to eliminate (which is not completely eliminated, but is considerably reduced) caffeine, and Not all are equally healthy. To the point that some methods They are under the radar of organizations such as the US FDA. Image | Justin Bhalla In Xataka | There are more and more studies that link coffee with living more. And it is very easy to put the leg when preparing that ‘philosopher’ coffee

My real experience with the Aura Triple Aero 15.6 “Pro Max

by

I have spent recent weeks using the Aura Triple Aero 15.6 ”Pro Maxrimbonbante name for this device consisting of three external monitors that fold in one piece. Your promise is that you can turn any space into a workstation with 43 inches of screen. After using it both at home and in a hotel, I have a clear perspective for who makes this product of 520 euros. The first time I deployed the three screens at home I felt that immediate satisfaction of having plenty of visual space. The deployment is not entirely intuitive, but once you understand it, it is fast: about thirty seconds have passed since you put it on the table until you have everything working. A single USB-C cable from my laptop-which transmits both image and energy, as it should be-in addition to the power supply, and the three screens come alive. It is elegant in its simplicity. Image: Xataka. But here comes the first nuance: This weighs 3.2 kilos. It is not very much, but it is not a trivial weight when you already load with more luggage. In addition, the dimensions tell: in my usual backpack it is not possible, one of the greats is needed. The 15.6 inches come in pleasure, the problem is the metal structure that surrounds them. I had to reorganize my cabin suitcase, where it enters very tightly. A centimeter more thickness and would have to use another suitcase, of those that do not enter the cabin and have to be billed. If it becomes a few centimeters larger, I would not have entered the cabin suitcase. But he entered. Image: Xataka. Then we arrive at another nuance: the reality of the full HD in the middle of 2025. I come from working with a 4K monitor at home (Something else, in fact), either to use the 14 -inch laptop screen. The difference in sharpness is palpable. MacBook Pro 14 “: 3,024 × 1,964 pixels. Density.254 ppp. Huawei Mateview 28,2 “: 3840 x 2560 pixels. Density: 163 ppi. Aura Triple Aero 15.6 “Pro Max: 1920 x 1080 pixels (each panel). Density: 141. And not only sharpness, the quality of the panel also falls behind. IPS / WLED panel, maximum brightness of 350 nits and contrast 1,200: 1. The three 1080p screens of the aura are functional, but when you are accustomed to the density of pixels and the quality of a modern panel, the text is no longer fully clear. Image: Xataka. Using these panels I got an email from a Baltic person, and I could simply distinguish if what was about a vowel of his name was a point or a tilde. It turned out to be a point. It is the type of concession you can accept on a travel devicebut that completely discards the aura as a permanent replacement for my desktop configuration. I do not think that is his intention, but it is good to take it into account in case that temptation arises. Admitted resolutions. Image: Xataka. Possibilities of disposition or duplication of screens. Image: Xataka. During my stay at the hotel, the test came with the real use. I had to prepare a couple of interviews documented and preparing the questions, and analyze the balance of a company related to the above. There, the aura shone. Be able to review spreadsheets and maintain Notion Open, adding the browser in sight, and Apple Music in a third panel … I felt it was worth it. The fact is that the work had already begun at home, there I just had to give him the final auctions. Less than two hours of use. The process of riding, configuring, disassembling and especially loading the system in the suitcase during the entire trip made me question if it had been worth it The space sacrificed in the suitcase and the three extra kilos. Something characteristic that did not expect to assess is the ability to use screens in different provisions. You can put them straight, lean the sides to you as if it were a Cockpit… or something surprising: put them in the form of a triangle. The panels are de facto have the magnetized edge to get well if you want to use them like that. You can make the experience more immersive guiding the side screens towards you … Image: Xataka. … or you can put them in a triangle shape so that those who are around can see what you show on the screen without the need to get together in front of the main panel. Image: Xataka. Cenital view of the triangular disposition. Image: Xataka. It makes sense to A case of specific use: Allow several people to see the screen on the screen simultaneously and without having to pile up, simply being around a table. It is true that it is very useful in that case, but it is also true that it is a tremendously specific case. This device brings integrated speaker, oriented towards the back of the central panel. It works, but don’t wait miracles. They sound better and with better orientation the integrated in my laptop. The support is robust and offers three heights, although the lowest position is unstable with the weight of the set. It is a frame that must be treated with some care. By the way, the product box came both with temperate crystals for the three panels and with the case. Image: Xataka. All that is sold separately, but I would say it is almost imperative for those who buy the aura. Swork everything, the case. Without it, the external screen exposed when the device is folded is an invitation to the disaster. This product is not exactly plug and play: It is necessary to download your drivers From the manufacturer’s website, but once installed, the use is immediate. The central issue with the aura is who makes sense for. It is a unusual pinton product, of which we stop to examine when … Read more

The most powerful countries in Europe according to their GDP, grouped in this graphic developer

by

GDP is the main thermometer of the size and growth of the economy of a country. This has traditionally been reflecting the value of the goods and services produced within a country And it is something that allows us to compare the performance between regions. But, if lately it has been more on everyone’s lips, it has been for the Ukraine Warby the REQUIREMENT OF US ADMINISTRATION in terms of defense and for the European rear. Given this, it is interesting to take an eye on the situation in Europe, comparing the GDP of their countries and regions to have a more global idea of ​​the economy of the neighbors. And this graph shows it perfectly. The pizza. Prepared by Visual Capitalist and using the International Monetary Fund As a source, we can see in a very clear way the size of the economy of the different countries. But there is something important to take into account: if the GDP of any of these countries does not fit you (that of Spain, for example, it was 1,593,136 million euros in 2024 and there it says that it is 2,800,000 million dollars, the fault has the parity of purchasing power. Parity of what? PPA -Parity of purchasing power or PPP in English- is a correction that allows us to compare more directly the price of goods and services between countries. The graph has been prepared by adjusting the GDP by PPA, which allows the size and purchasing power of the different economies. What is this for? In order to measure what can really be purchased locally instead of directly transforming GDP to the international standard change, which is usually the US dollar. Thus, and using an exchange rate that eliminates the distortions of the different currency markets, the panorama is more fairly compared. In short: Economies with undervalued or overvalued coins with respect to the dollar are represented in a more adjusted way to reality and the standard of living, economic well -being and real size of the economies can be better compared. By zones. Given this, we see that, apart from Russia, Germany, the United Kingdom and France, there are more aligned economies such as Italy, Spain, Poland or Netherlands, those four above 1,000 billion dollars, and then the rest of the countries. But, if we distinguish in zones, we see the enormous weight of the aforementioned Russia and Germany. The western zone has a GDP adjusted per PPA of 14,800,000 million dollars for the 12,800,000 of the Eastern Europe. The southern Europe (curiously the so -called ‘Pigs’) with Italy, Spain, Portugal or Greece has that adjusted GDP of 8,300,000 million and that of the north (including the United Kingdom and with Sweden, Ireland, Denmark, Norway or Finland) with a GDP per PPA of 7,800,000 million. Unequal growth. When the nominal GDP is measured, the thing changes. Western Europe would continue first with a GDP of 11,000,000 million, the north with 6,500,000 million, the south with 5,200,000 million and Eastern Europe is the one that falls loudly with 4,600,000 million. Reason? Adjected to the PPA, Russia occupies a huge portion of the cake, but the nominal GDP relegates it to the middle part of the table with a GDP of 2,100,000 million. These regional disparities are what has historically marked a two -speed economic development. Europe has been adjusted and changes for a few years. In that panorama, Russia Lithuania, Iceland or Montenegro are from the countries that grow the most this year. Luxembourg, Ireland or Estonia, decrease. Others grow (Spain), and we see cases such as France or Germany in stagnation. In general, the growth From the Eurozone it was 0.7% and the European Union of 0.8%, but we must see how situations such as external factors, structural tensions or industrial slowdown in some countries to the photo of the European GDP of 2025.

How the Atacama desert shows the ecological price of decarbonization

by

Lithium has become white gold. Has become A strategic element Due to its importance in the global energy transition. Among other things, and While we find alternativesis what allows us to create batteries for electronic devices, but also critical systems for the decarbonization such as electric car batteries and those of renewable energy storage. There is a problem: extracting it requires huge amounts of water. Chile has one of the greater lithium reserves in the worldand its exploitation shows us the hidden cost of the energy that wants to “save” the planet. Atacama. The Atacama desert, located in northern Chile, is very peculiar. It is about driest desert in the worldbeing 250 more arid than the Sahara. It is a gigantic garbage dump Due to the fast fashion culture, but it also has huge solar parks that are the country’s energy pride: 500 operational projects and another hundred under construction. In addition to sun, there are minerals like copper –that China is accumulating at pleasure-, iron, gold and silver, but also other strategic such as Boto or Lithium. Within the region, the Salar de Atacama stands out. It is this area that has large lithium concentrations that have allowed Chile to become the largest global exporter of this element during the last two decades. It is so important that the Chilean regulatory regime gives the State property over lithium, considering it “Non -concessionable” and restricting foreign exploitation only to special contracts. Salar in 1995 In 2005 And today Ecosystem transformation. In the superior images we can see how the landscape of Salar has been transformed from 1990 to the present, with Lithium farms Greater and bigger. And something that we can see with the naked eye is the amount of huge ‘swimming pools’. The process of obtaining lithium is based on the evaporation of brine, being something that consumes billions of liters every year that is extracted from both the surface and the subsoil. In Atacama Salar, that is causing sinking, Loss of vegetation and of the rich microscopic diversityas well as the emblematic fauna of the place: the flamenco. Faviola González, biologist of the Chilean National Reserve, is one of those who complaint that the population of flamenco has decreased in recent years. It is not just your observation. As we read in the BBC article, the Natural Resources Defense Council, based in the United States, published a report in 2022 in which it indicated that almost a third of the native Algarrobos began to die in 2013 due to the impact of mining. Without brake. This transformation of the landscape has led to judicial demands, especially by indigenous communities that denounce the degradation of water resources and the loss of cultural identity of the desert. Because yes, Atacama’s is a desert, but with great biological wealth. The problem is the aforementioned Importance of lithium for the country. Chile is within the so -called ‘Lithium Triangle’ with Bolivia and Argentina and, as the second largest world producer and holder Of the largest reserves on the planet, it has the power to dominate the supply chain. It is an economic engine, with a value My dear of exports of 2,895 million in 2024, and its importance will go more. HE wait That the global lithium demand exceeds 1.3 million tons in 2025, with the forecast to triple by 2040. Measures to mitigate damage. And here comes the big question: if the lithium is needed to decarbonize the planet, but at the same time we are damaging the ecosystems in their obtaining, is there nothing we can make? Valentí Barrera, SQM Lithiuum Sustainability (the Chilean company that manages some of these farms) affirms that understand the concerns of indigenous communities and are carrying out pilot programs to mitigate the impact of mining. One is the Lithium extraction directly from brinewithout the need for evaporation pools. Another is the reinjection of water on earth once the lithium is obtained. The problem is that they are arguments that do not convince those who live from that land, who have seen the ecosystem disappear and who They affirm that they do not have a significant carbon footprint and that electric cars will go to Europeans and American, but contaminated water will be left. Because at some point, lithium will run out and the miners will leave. EITHER The price will fall so much which will cease to be profitable to extract it to Mansalva.

Young Koreans just want to be doctors

by

While the two Koreas seems to be giving a trucewho knows if something else, the southern neighbors live with anguish a problem that has been entrenched too long: in an increasingly aged country, becoming old is a condemnation of poverty. And the young? They are also indirect protagonists of this endemic evil: they have agreed to study the same. Brain drain. In South Korea there is an unprecedented phenomenon: students even leave the most prestigious universities from the country (Seoul National, Yonsei and Korea University, known as the Sky Group) to pursue A career in Medicine. Only in 2024 they were recorded 2,481 dropouts In these three institutions, the highest figure in 18 years and 17% more than the previous year. Most of the deserters They came from the natural sciences and the humanities, attracted by the expansion of access quotas to the faculties of Medicine, which passed 3,000 to 5,000 places Annual in a government attempt by alleviating the shortage of doctors in an increasingly aged society. Medicine, perceived as the most prestigious and profitable profession in the country, has become the preferred destination even for those who had reached the quoted places of the elite universities. Pressure on medical schools. The change, however, is overflowing capacity of medical faculties, which already dragged structural problems. Overloaded teachers, massive strikes and classrooms They are now the norm, in a context where resources do not grow at the same rate as demand. At the same time, fundamental disciplines such as basic sciences and humanities They suffer from emptying that threatens the intellectual diversity of the country and erodes the long -term innovation potential. Academics like Theodore Jun Yoo They warn that this trend mine educational balance and puts at risk the production of critical thinking and technological advancement, while The low birth rate It reduces the need for new teachers and researchers, weakening the national academic base. The roots of the trend and the AI. The rise of this career towards medicine does not arise from nothing. Studies show that since 2022 more than A quarter Of the students with the best notes in the university admission exam, medicine to Sky universities have preferred, a sign that traditional disciplines have lost attractiveness as an option for the future. For academics such as Robert Fouser, the proliferation of artificial intelligence and the perception that humanities and sciences already They do not guarantee stability work have accelerated the leak. Japan experiences A similar phenomenonwith young people who choose regional medical schools instead of specializations in social or humanistic sciences in Tokyo, which reflects a regional pattern of more armored careers in the face of technological disruption. Mental of medicine. Paradoxically, some experts point out that this fever for medicine can Not being the panacea or the best bet In the long term. The profession itself is exposed to deep transformations derived from AI and demographic changes that are already affecting pediatrics, reduced by Birthday fall and the displacement of professionals towards more profitable specialties such as dermatology. In other words, this suggests that, in the long term, engineering or technological development careers could Offer more resilience than an overcrowded medical profession. Proposals to stop the crisis. Given this panorama, more and more critical voices ask the government to act quickly. It is raised Medical training more and force new graduates to work at least six years in rural areas, where the shortage of doctors is more pressing. These measures are looking for stop the avalanche towards the faculties of Medicine and redistribute human resources more balanced. However, the situation reflects a substantive tension: social obsession with economic stability and prestige, in the face of the national need to preserve a diverse university system capable of sustaining innovation and technological leadership. Educational crossroads. The “career towards medicine” in South Korea not only reveals social anxieties about the future work, but also exposes the limits of a model that privilege a single path to the detriment of other essentials for the integral development of the country. The risk It seems clear: In the search for individual security, the collective capacity of producing new ideas, of forming critical thinkers and of guaranteeing a balance in professional training is undermined. If you also want, the final paradox is that, in its attempt to ensure more doctors, South Korea could be weakening precisely the bases that have allowed it to prosper as one of the more innovative economies of Asia.

The Arctic cold was the ideal barrier against invasive species. Now that barrier is falling

by

The Arctic Ocean is one of the hot points as far as climate change is concerned. Separated from the surface by polar ice, this ocean is a place with its own characteristics that go beyond its icy temperature. The barrier falls. A new study headed by researchers at British Antarctic Survey (BAS) He has found evidence of the arrival of an invasive species of Percebe to the waters of the Canadian Antarctic. This has led the team to conclude that the barrier that previously represented the low temperatures of the polar ocean is falling. Amphibalanus Impherevisus. The species in question is a type of Balánido sometimes known as bay’s percebe (Amphibalanus Impherevisus). These crustaceans are disturbed in a distant way with the common perclabes (Cornucopia policipes), but its presence is considered a problem and not A food source. The species has already become a regular of the waters of Europe and the Pacific Ocean, where it causes problems when attached to ships, pipes and infrastructure of different types. However, until now it had remained absent in the waters of the Canadian Arctic. EADN. The detection of the invasive species was carried out thanks to the study of the bars coding of the Environmental DNA (Edna). Living beings are leaving our genetic imprint in our environment: detached cells, waste and other biological remains. This technique allows to detect the presence of a species (or several) without finding a single specimen, only through environmental samples, in this case, water. The details of the study were Published in an article In the magazine Global Change Biology. Climate change, the great suspect. The Arctic is one of the regions most affected by climate change. There are two factors, both related to the increase in temperatures in this region, which have contributed to the expansion of this percebe. The first factor is the increase in maritime traffic of the Arctic associated with the thaw and the opening of new routes. Generally, the team explains, these invasive species usually arrive in the ships of the ships or in their ballast tanks. The second factor is that the waters of the Canadian Arctic no longer present such hostile conditions for the proliferation of foreign species. “Climate change is really in the nucleus of this problem. The ships are increasing in number because the reduction of sea ice has opened new nautical routes. It adds to this that the invasive species that the ships bring to the Arctic also are more likely to survive and establish populations due to the warmest temperatures of the water,” explained in a press release Elizabeth Boyse, who led the study. An issue to clarify. According to the team responsible for the study, there are still details to corroborate with respect to the spread of this species in the Canadian Arctic, starting to know if the DNA detected responded to larvae in transit or a more stable and fruitful population. To know this type of detail, it will be necessary to complement the study with other techniques, such as direct observation of animals.

74,000 years ago, a volcanic eruption led humanity to the edge of extinction. We begin to understand how we survive

by

74,000 years ago, in a remote lake north of Sumatra, a volcano erupted. But it wasn’t a normal volcano. According to archaeologist Jayde N. Hiniak“The Toba expelled 2,800 cubic kilometers of ash to the stratosphere, created a crater of 1,000 soccer fields” and caused a global winter. That could take our species to the edge of extinction: for more than half a century, many anthropologists are convinced that it was that eruption (one of the greatest known eruptions) that reduced the human population to about 10,000 fertile couples. It would be the most critical moment of Homo Sapiens since it arose. It is true that the theory is controversial and the debate around the real climate change that the Toba created is still very alive; However, no one doubts that what happened that day in Sumatra was a huge catastrophe. And that can be seen in archaeological remains. As Hiniak pointed out“Most archaeological sites show a history of resistance.” In areas such as South Africa or the lowlands of Ethiopia these climatic changes led to the adoption of technological innovations such as the development of arches and arrows. In much closer places (such as Indonesia, India or China), the population also suffered deep changes that allowed him to survive. All this can be known because the Toba left many geological samples distributed throughout the world. Studying the deposits before and after the ash of the volcano gives a lot of information on how these societies changed socio-technologically. The flexibility was key. Regardless of what Toba will cause (or not) drastic reduction Of the population, what is clear is that it allows us to draw conclusions about what was the fundamental feature that explains the survival of human communities: behavioral flexibility.

If there is something that sister a multitude of countries at this time, that is the deep housing crisis we are going through. In Spain, and according to Idealisticthe average price of the square meter has triggered more than 40% these last five years. If we look at what the neighbors do, we have cases that are familiar to us. For example, Almost 10% of its real estate park are second residencesand in London it is so serious that They are uploading taxes to Mansalva. In the search for solutions, an idea has occurred to Paris: convert offices and parking lots. And he wants to do it with a coup d’etat. Social Housing. Paris is one of the European cities that is investing the most when creating protected housing. Fruit of different actions of these last decades, They have passed From about 126,000 social homes to almost 272,000. Currently, the Social Housing Park in the French capital is around 25%, but although the administration has increased Public spending up to 800 million euros (28% more than the previous figure), the demand is so high that it cannot be satisfied. What does this translate? In which, although there is more protected housing, prices are exorbitant. The mayor of Paris, Anne Hidalgo, commented Recently, young people cannot access housing because “it is almost impossible, the price level is tremendous,” stating that without family support they cannot access as owners. And to solve it, they have begun to use the law. 2025-541. That is the number of a law that France promulgated in June of this year with the objective of facilitating the transformation of non -residential buildings. It is a regulation that gives the urban administration the power when allowing the change in the use of buildings, even if it contradicts local urban plans. As? Facilitating the transformation of offices and other non -residential buildings, such as parking, in homes. Besides, contemplate a reversible license which allows to modify the use of a building between residential and office without the need for new permits, all with the aim of expediting processes. Truillot garden Transformation. The purpose is to encourage the creation of housing in areas that already have an infrastructure, but whose qualification is not residential. That is, instead of Raise new floors (A longer and more expensive process), what they want to encourage is that certain spaces be remodeled to be converted into homes. It is another step in a practice that the French capital has been carrying out in recent years. It is estimated that 70% of urban permits issued since 2020 are linked to structure reconversion projects, an example being both both the Truillot garden (It was a parking lot and now it is a green space with urban garden) like the Lamarck Street parking which will become a mixed space of offices, homes, sport and social areas. It is something that also affects administrative buildings, such as the conversion of premises of the Ministry of Defense on 254 social floors. Truillot in 2014 And in 2024 Ambition. The objective of these proposals is to reach 40% of social housing before 2035. It is very ambitious if we take into account that they move in current 25%, a figure that took 20 years to reach. In addition, new projects must have a series of common characteristics such as efficient energy systems to achieve decarbonization objectives and have green areas, betting on a model of “vegetation“Of the neighborhoods. It is something that even has taken debate In Europe. An attack. Now, this plan has harvested criticism and doubts about its true impact when solving the housing crisis. Among the latter, there are who He thinks That betting on the conversion of empty offices is something that only responds to creating the illusion of acting in times of crisis, since the volume of really transformable offices is not so high and the figures will remain below the political objectives. In addition, it is not a simple process. HE points to transformable offices that have a good amount of years behind them, so the process would be complex and expensive to be energetically poor buildings that will have to adapt deeply to comply with residential regulations of light, ventilation and accessibility. Finally, and beyond political criticismit is estimated that the cost of rehabilitation would be so high that private companies would be discouraged by doubts about the return of investment, forcing To these expensive projects are financed with public aid.
