We have been believing for decades that the Great Pyramid was built at one time. The latest analysis places it more than 20,000 years earlier

by

(Fortunately) the world is full of monuments as ancient as they are impressive, but few, very few, are comparable to the Great Pyramid of Giza. Almost 140 meters high, thousands of years old and an immortal testimony to the power of Ancient Egypt. It has such magnetism that every year they visit it millions of people arrivals from all over the world. But… What if we have been wrong about its origins for decades? What if instead of becoming 2,500 BCas we have always believed, rose up ago more than 20,000 years? What if Pharaoh Cheops was not its true promoter, but simply renewed it? All those questions have been left by launching a new (and controversial) study. What has happened? That Egyptology has just been shaken by unusual news in modern archaeology: a study that has turned upside down the dating (and origins) of the Great Pyramid of Gizaone of the most iconic monuments not only in Egypt or Africa but on the entire planet. Until now, experts agreed that the monument was built in the time of Khufu, around 2589-2566 BCbecoming one of the Seven Wonders of the Ancient World and the tallest structure in the world for 3,800 years. For Alberto Doninian Italian engineer from the University of Bologna, that estimate falls short. Very short. In fact, he has published a study in which he traces the origins of the pyramid back to more than 20,000 years. What dates do you handle? After analyzing several points of the pyramid, Donini has come to the conclusion that the reference date to talk about its origins should be another: 22941 BC That is, their calculations indicate that the structure is around 24,900 years old. Before continuing, it is important to clarify one detail: its analysis does not seek to set specific dates, but rather to establish a time frame for the construction of the monument. What does that mean? That, in reality, what Donini has done is calculate that there are 68.2% probability that the period of construction of the pyramid is framed in a window that extends between 38,903 and 10,979 years ago. The calculation of 24,941 years would therefore be a simple arithmetic mean that serves as a reference. If instead of talking about antiquity we talk about calendars, this means that, according to the estimates of the Italian engineer, the most famous structure in Giza was probably built between 36878 and 8954 BC What is it based on? Donini’s work is not controversial only because of its conclusions. It is also because of its methodology, the calculation system it has used. Its main tool is Relative Erosion Method (REM), a formula that dispenses with documentary sources to be based fundamentally on what the rocks say. Literally. What the REM does is analyze the erosion of the pyramid blocks to, based on their level of wear, date them. Said like this, it sounds simple, but what the engineer has done is somewhat more complex: he selected 12 different points spread across the base of the Great Pyramid and then compared their different levels of erosion, looking at aspects such as the holes and cavities opened in the rock by rain or the roots of plants and the natural wear and tear caused by wind, sand and the constant passage of people. And has that been of any use? Yes. The analysis has yielded a disparate range of dates. At one of those twelve points, the REM suggested an estimated age of 5,708 years. In others the estimate was 17,955, 30,375 or even more than 50,000 years. It may sound strange considering that we are talking about a single monument and it is logical to think that all its blocks have been there for the same amount of time, but many factors influence erosion: from the position of each stone, which determines its exposure to wind and rain, to its mineral composition. It’s still a strange thing, isn’t it? Yes. And no. It is true that the engineer obtained very different dates, but this is explained by another peculiarity of the Great Pyramid. The monument did not always have the appearance we see today. In it 1303 AD The area suffered an earthquake that affected the white limestone blocks that originally covered the structure. That material was later reused in buildings in Cairo. Although it may sound like an archaeological tragedy, it offers experts like Donini a real opportunity. The reason? They now have blocks that have been exposed to erosion almost since the construction of the Great Pyramid and others that have only been exposed to erosion for 675 years, when the earthquake left them bare. This contrast partly explains why when applying the REM method Donini obtained such a broad time frame, the same one that later led him to propose an antiquity of 24,941 years. Issue settled, then? No. The study has only served to stir up the debate. And it is more than understandable if we take into account several keys. First, the dating turns upside down everything we thought we knew about one of Egypt’s most famous monuments. Among other things, he questions whether Pharaoh Cheops was its main architect and slips that he could have limited himself to reforming it. Furthermore, Donini’s study has another handicap: it is preliminary and has not been peer-reviewed, which heats up the debate (even) more. He himself has admitted that REM calculations are influenced by factors that must be handled with caution, such as the variability of erosion processes or the wear and tear that mass tourism may have had on certain parts of the base of the pyramid, altering the calculations.

We have been cooling homes for decades with increasingly expensive machines. The Persian method has not consumed a single watt for 2,500 years

by

For decades, air conditioning has been the great response to heat. The more the temperatures rose, the more powerful the machine we installed was. However, more than 2,500 years ago, in a city in the Iranian desert, someone proposed an idea completely different: Maybe the problem was not how to cool a house, but how to build it so that it never got too hot. The heat has a new enemy. The planet is going through an escalation of unprecedented temperatures and the buildings are starting to pay the bill. Glass facades turn offices and homes into veritable greenhouses, concrete accumulates heat for hours and cities radiate energy at night. absorbed during the day. The consequence is an increasing dependence on air conditioning. According to the United Nations Environment Programme, cooling systems already consume about 20% of all the world’s electricity, a figure that will continue to grow as heat waves become more frequent. The Persian redesign. In the heart of the Iranian plateau is Yazda city where summer temperatures easily exceed 40 ºC and where survival was never a question of comfort, but engineering. There appeared one of the most sophisticated passive cooling systems ever conceived: he badgirknown as a wind catcher. His approach was radically different from the current one. Instead of combating the heat once it had entered the house, the architecture itself took care of it. to capture the fresh airexpel the heat and maintain a habitable interior without consuming electricity. Yazd The “Persian method”: a way of thinking. At first glance, a badgir It looks like a tall, decorative chimney jutting out from the rooftops. In reality, it is a carefully calculated system to take advantage of two natural phenomena. On the one hand, it captures the air currents that circulate several meters above the ground and channels them towards the interior. On the other hand, even when the wind hardly blows, it acts as a solar chimney: Hot air rises through the tower and, as it escapes, creates a depression that draws cooler air into the building. In many homes, this flow also passed over underground water tanks or connected channels. to the qanatsfurther increasing the cooling effect. A bâdgir in Yazd A city designed for the climate. The truly extraordinary thing about Yazd is that the badgir It did not work in isolation. It was part of an architectural ecosystem where each element fulfilled a function. The thick adobe walls slowly absorbed the heat. The inner courtyards they created microclimates protected from the sun. The qanats They transported groundwater from the mountains and helped cool the air. There were even the yakhchalenormous structures capable of manufacturing and preserving ice for months in the middle of the desert. The result was a city designed to work with the climate, not against it. Yakhchal in Yazd And the air conditioning arrived. During the 20th century, much of the Middle East and other warm regions embraced imported architectural models that had little to do with their climatic conditions. Concrete replaced adobe, glass facades replaced solid walls and passive solutions were giving way. to mechanical systems. Many badgir they were abandoned due to the lack of maintenance, due to the entry of dust or insects and, above all, because the air conditioning offered an immediate response. The problem is that it also moved energy consumption to the center of the equation and made cooling a permanent necessity. The irony of the West. As many wind towers fell into disuse in Iran, their principles were beginning to reappear discreetly in other parts of the world. Between the end of the seventies and the mid-nineties, thousands of modern versions of wind sensors in British public buildings. Shopping centers, hospitals and schools incorporated ventilation systems inspired by those ancient designs. In the United States, the Zion National Park visitor center was able to drastically reduce the need for air conditioning thanks to passive cooling strategies based on the same concept. Today architects and engineers they resort to simulations by computer to optimize a technology that was born centuries ago simply by observing how the wind moved. The future may not be in more efficient machines. Contemporary architecture begins to take on an idea that for decades was relegated to the background: the building is also part of the air conditioning system. Recent regulations in countries like uk They prioritize shade, natural ventilation and reduction of solar gain before resorting to mechanical solutions. Exterior blinds, slats, vegetal covers, materials with high thermal inertia or patios return to gain prominence. Even those who defend the use of air conditioning agree that these measures can significantly reduce energy consumption. The big lesson: don’t repeat the same mistake. The history of the Persian method and its badgir It does not prove that we should give up air conditioning. prove something much more uncomfortable: For decades we have tried to solve heat by adding machines to buildings that, in many cases, were designed as if the climate did not matter. The Persians followed the opposite way more than two millennia ago. Before thinking about how to cool a house, they thought about how to build one that needed to be cooled as little as possible. Perhaps the most revolutionary technology to face the next heat waves is not a new machine, but recover an old idea that had been waiting for centuries on the rooftops of the desert.

We have spent decades blaming a lack of willpower for obesity. Genetics Just Proved Us Wrong

by

For decades we have heard about overweight and obesity that it is a problem of lack of willpower, of eating too much or moving too little. However, science has been trying to find more causes for years that we do not see with the naked eye about obesity to treat it as a complex, chronic disease with many different factors. Two great studies recently published studies have provided very important evidence that suggests that the way we relate to food and the size of our body in childhood are not always ‘choice’, but are, to a surprising extent, an inheritance dictated by our DNA and amplified by the environment. The weight of inheritance. The first of these studies published in PLOS Medicine analyzed to 86,000 children belonging to the Norwegian MoBa cohort. The goal here was to understand the extent to which parents’ BMI determines body size and the eating behaviors of their children at eight years of age. The results have exceeded what many geneticists expected, since, using structural equation modeling, researchers discovered that genetics explains about 79% of the association between the mother’s BMI and that of the child. When we look at the father, the figure is even more compelling, since DNA explains approximately 94% of the association between the paternal BMI and that of the child. Its importance. This means that when we see patterns of obesity that are repeated from parents to children and the determining factor is not mainly that “that house eats badly”, but that genetic variants are being transmitted that regulate key physiological aspects, from basal metabolism to the brain architecture that dictates the mechanisms of satiety and reward when eating. The environment. At this point, it is inevitable to ask a reasonable question: if genetics is so determining, why have obesity rates skyrocketed in recent decades if our human genome has barely changed? The answer the second study gives itpublished almost in parallel in PLOS Genetics where British researchers analyzed four large birth cohorts in the United Kingdom, namely people born in 1946, 1958, 1970 and 2001. The goal here was to measure how genetic risk interacts with the passage of time and changes in society. Its result. What they saw was precisely that the genetic variants associated with obesity have become much more predictive of BMI in more recent cohorts. That is to say, having a genetic predisposition to gain weight in the forties did not necessarily ‘condemn’ obesity, because the environment did not support it. However, being born with that same predisposition in 2001 exposes you to a much greater risk. Our genes interact with what epidemiologists call the obesogenic environment, which are sedentary urban environments, chronic stress, sleep disturbances and, above all, a constant, cheap and ubiquitous availability of ultra-processed, high-calorie-density foods. The modern environment acts as the trigger of a weapon that genetics had already loaded. Much further. This avalanche of empirical data collides head-on with social stigma. As organizations such as the Spanish Society for the Study of Obesity have been warning for some time, it is urgent banish “Eat less and move more” is the only recommendation given in medical consultations. It is for all this that understanding that obesity is a condition with a very deep genetic root, strongly conditioned by the environment, completely changes the rules of the game.

Today in streaming, one of the most epic box office failures of recent decades receives a portrait worthy of its legend

by

Mike Figgis sent an email congratulating Francis Ford Coppola for resuming, forty years after imagining it, a project called ‘Megalopolis‘, a film financing and collection apocalyptic He added a postscript half jokingly: if he felt like it, he could document the filming. Coppola accepted, and thus ‘MegaDoc‘, that Filmin premieres today. Figgis had full access to the filming, without a script or preconditions. Figgis and Coppola had known each other since the nineties, when the Briton directed Nicolas Cage, the director’s nephew, in ‘Leaving Las Vegas’. In November 2022, when filming began, ‘Megalopolis’ was the biggest unknown in American independent cinema: a science fiction fable set in a New York inspired by Catiline’s conspiracy against republican Rome, financed entirely by Coppola with more than 120 million dollars from the sale of part of his wine business There is a very interesting detail in the nature of ‘MegaDoc’. Eleanor Coppola, the director’s wife for more than sixty years, died on April 12, 2024, just a month before the premiere of ‘Megalopolis’. It was she who in 1991 directed ‘Corazones en tinieblas’, the documentary about the filming of ‘Apocalypse Now’ that became the making of in its own genre within documentaries. ‘MegaDoc’ inherits that family tradition of documenting the creative process from withinalthough this time it is a filmmaker from outside the clan who holds the camera. In ‘MegaDoc’ we will see Shia LaBeouf’s confrontations with Coppola, who even told him that he was the most difficult actor he had ever worked with. Aubrey Plaza turned Figgis almost into another character in the film, ordering her without leaving her role as the Wow Platinum presenter to follow him as if it were her personal camera. Adam Driver, the protagonist, asked not to be filmed during filming and only gave an interview at the end. The result is a documentary as eventful and as peculiar in its destiny as the film it portrays.

Air conditioners have been wanting to reach the north of Spain for decades without much success. Until the thermometer passed 40ºC

by

Here a server is writing these lines from Vigo, with the thermometer reading 28ºC (a temperature that in a few days will fire at 35ºC) and without air conditioning or ceiling fans. My only weapons against the haze are a small table fan that is almost (almost) the same decades old as me and the assurance that, no matter how hot the heat was, the temperatures in Galicia would always be tolerable. The first (the antediluvian fan) may not have done much, but the second did. Or so it was until now. In view of the heat waves that are coming at home, we are already thinking about installing a system that allows us to cool off with dignity. And we are not the only ones. On the contrary. We are one of the many homes from the northern peninsula that already look at brochures of air conditioners and fans. Ready for the heat? In the south of Spain it’s hotter than in the north. That was true before, it remains true now, and probably not much will change in the future. As I write this I enjoy a peaceful 28ºC in Vigo, eight degrees less than what the mercury shows in Córdoba. The problem is that there they are probably much better prepared to weather the heatwave than in this northern part of the country. I’m not saying it. The INE says it. From 64% to 0.4%. Although she is almost 20 years old, the Household and Environment Survey from the INE clearly shows that acclimatization facilities are much more frequent in the Mediterranean or Levant than in northern Spain. While in 2008 54% of homes in the Valencian Community had air conditioning, a percentage that rose to 57% in Andalusia, and 64% in Murcia, in Galicia, the Basque Country, Asturias and Cantabria the indicator did not reach 2% in any case. In the Principality it actually marked 0.4%. The INE data is old, but the SER chain recently disclosed a more recent survey confirms that the air conditioning map is still clearly divided between north and south. According to that study, only 17% of northern homes are acclimatized to the heat, far from 86% of the Mediterranean coast. Another Idealista report shows a gap even bigger. Changing the mentality. If they repeated that survey in a few years, it is likely that the ‘photo’ would be somewhat different. The heat wave that has shaken Galicia, Cantabria, the Basque Country either Asturiasleaving in some cases record temperatures that exceeded 40ºC, with hospitalizations due to fainting and deceasedhas led many families to look for new ways to cool their homes. Take a quick look at the regional press to check it out. Skyrocketing sales. In May The Montañés Diary counted how the demand for fans had skyrocketed by more than 80% in some businesses in Cantabria. Installers and stores of air conditioners and portable appliances also noticed the boom. I had something similar recently The Voice of Asturiaswho has spoken with companies in the sector that have noticed a 25% increase in requests for information. The Basque Journal confirm also an increase in the sale of ceiling fans, just like The Region in Ourense. From shops to homes. The most interesting thing is that the demand for devices does not come only from businesses. Andonio Suárez, from a company in the industry, recently recognized to ‘Hoy por Hoy Cantabria’ who in their business “do not stop” touring the community to install air conditioners. Not only that. Their technicians have gone from working basically in commercial premises installations to doing so in private homes, homes of people tired of being in the heat. “It is practically 50% between homes and businesses,” resume. “Before we managed”. Patricia lives in the province of Pontevedra and is one of the people (more and more) who has begun to think about ways to cool her home, beyond the use of floor, ceiling or table fans. “We had always managed, but now we are studying switching to a portable air conditioner or air conditioner because the fans fall short,” he confesses. In mind, you have devices that do not require the installation of exterior elements, such as evaporative air conditioners or tubeless air conditioners. “We save trouble and can take them from one home to another.” Poorly prepared floors. “The summers are longer and hotter, and the heat waves are more frequent. This year we already had a month of May with a week of tropical nights in which it was difficult to sleep, another in June, and summer had not yet started. A month of July is approaching in which it does not seem that we are going to go below 30ºC on most days,” explains Patricia before remembering that many of the apartments built between the 70s and 90s in Galicia “are not prepared nor do they have good insulation.” for the heat. “It has turned against us”. His experience is similar to that of Manuel, another Galician who recognizes that his house is designed to conserve heat, something ideal in winter, but not so much for the months from June to September. “The increasingly hot summers have turned against us.” Hence, she has opted for two portable air conditioners that she places in the living room and in her daughter’s bedroom, the room that accumulates the most heat. “I had been thinking about it for a while. Years ago it was not something that compensated, since it was not really necessary; but in the last five or six years the heat has been much more intense, even reaching days of 30-35ºC continuously.” More than just heat. Both Patricia and Manuel have opted for portable devices, which, among other things, they admit, has made installation easier for them. For systems that require an outdoor unit, it is necessary something more than you want to cool off: it is important to take into account both the municipal ordinances that regulate noise, urban aesthetics and … Read more

It had been collecting dust in a drawer for decades

by

Modern paleontology right now has two large fields of work, one of them being expeditions in remote places and the other being museum shelves. And it is no wonder, since the greatest discoveries are not made by breaking stones under the sun, but by cleaning dust from drawers that have been closed for decades. This is exactly what just happened to an antarctic fossil which, after years stored in the United Kingdom, has revealed to be a key piece in understanding our planet’s past. A new test. We are not facing the “first dinosaur fossil in Antarctica”, but rather we are facing the first fossil of this type that has been identified after a long wait in a ‘drawer’ of a museum archives. The files. The history of this bone is, in itself, fascinating, since, as has documented the BBC, the fossil has been in the British Antarctic Survey collection. For decades, it remained in a taxonomic limbo and although its existence and its Antarctic origin were known, the anatomical scrutiny necessary to classify it accurately had not been carried out. Now, a new study has put an end to the mystery, as researchers have reexamined the morphology of the bone and concluded that it belongs to a titanosaur sauropod dinosaur from the Late Cretaceous. Your base. To reach this conclusion we did not start from scratch, but there were already previous records about the presence of sauropods in Antarctica. What is interesting about this new study is that it connects the dots, providing the formal and rigorous identification that this piece of the archive needed to enter the history books. A green Antarctica. Identifying a titanosaur in Antarctica raises a mental image that clashes head-on with the current landscape of the continent. Right now we know that titanosaurs were a group of sauropods that included the largest land animals to ever walk the Earth. But the question we ask ourselves is clear: What was an animal of these proportions doing in an ice desert? The answer is that the Antarctica of the Late Cretaceous period was nothing like today’s Antarctica. Specifically, about 70 million years ago, the continents were arranged differently, since South America, Antarctica and Australia formed intermittent land connections. This means that Antarctica was not covered by kilometers of perennial ice, but instead was home to vast forests of conifers and ferns, an ecosystem rich and temperate enough to support the migration and diet of these gigantic herbivores. Its importance. From a scientific and informative point of view, the value of this news does not lie in a recent heroic expedition under snow storms, but in the relevance of institutional collections. The BAS fossil catalog shows that we still have fragments of Earth’s history gathering dust, waiting for current scanning technology or expert review to give them their true meaning. This fossil, now officially recognized in primary scientific literature, is not “the first Antarctic dinosaur,” but it is definitive confirmation that, in Earth’s remote past, there was no barrier or latitude that could resist the footsteps of a titanosaur.

Cancer in people under 50 years of age has been growing for decades. A macro study finally points to the big culprit: biological aging

by

The increasing incidence of cancer in young adults is one of the most debated topics in recent oncology. In recent years, exhaustive reviews have warned of an increase in diagnoses in those under 50 years of agealthough medical science had long been searching for the underlying mechanism that connects the dots between modern lifestyle and the early onset of this hated disease. The answer. A new study recently published seems to have found a key piece of the puzzle, which is nothing more than that our cells are aging faster than our ID card. This is the conclusion of research published in the journal Nature that indicates that accelerated biological aging is associated with a greater risk of developing early-onset cancers, especially solid cancers such as lung, stomach and also uterine cancer. Two concepts. To understand the finding, we must first differentiate between chronological age and biological age. The first of these is immovable, since it is nothing more than the years that have passed since our birth. But biological age is flexible, since it is calculated by evaluating the physiological state of a person through blood biomarkers and metabolic profiles. It reflects how “old” our tissues and organs really are. How to measure them. To measure this, Tian’s team used models already consolidated in scientific literaturesuch as PhenoAge and the Klemera-Doubal method. With these tools, they crossed the data of more than 150,000 adults from the UK Biobank and approximately 10,000 program participants. All of Us of the United States. The result shows a dangerous imbalance. This means that those people born in more recent decades had a greater tendency to have a biological age higher than that corresponding to their date of birth. And this time “jump” has direct clinical consequences such as the appearance of cancer. To be more specific, it has been seen that every time we have a person with a biological age higher than their corresponding age, they have an 8% higher risk of having early-onset solid cancer before the age of 50. If we compare the extremes, individuals located in the tertile with the greatest biological aging have a 15% greater risk of developing the disease compared to those in the tertile with the least biological wear and tear. The context. The main thing is not to fall into alarmism, since, although it is true that cancer is increasing in the youngest people in society, it is also increasing in all remaining bands due to multiple factors such as general population aging and better screening methods that allow us to detect cancer earlier. However, the specific data on early onset are undeniable, since large studies point to significant increases in thyroid, breast, colon, kidney and endometrial tumors in the 20 to 49 age group. Colorectal cancer, specifically, is the one that worries the most due to its escalation in young adults. The lifestyle. That we are biologically aging much faster than we should is not magic, but rather it seems to be influenced by different factors related to lifestyle. These include rates of youth obesity, prolonged consumption of diets rich in ultra-processed foods, a sedentary lifestyle, and exposure to environmental toxins. What this new work provides is the quantification of the damage, since these risk factors accelerate the biological clock. We must keep in mind that the human body is exposed to pro-inflammatory factors for more years from early stages of life, which makes it easier for DNA damage to accumulate faster than cellular mechanisms can repair it.

Spain has lost 17 factories in two decades

by

Not too long ago, Spain had a powerful household appliance industry: Balay, Corberó, Fagor… Between the 1950s and 1970s, manufacturers proliferated that manufactured refrigerators, washing machines and ovens “made in Spain” that constituted the middle class’s access to the comfort of the modern era. That era passed away: in the last two decades 17 plants have disappeared (they have closed or relocated) and barely a dozen remain in the entire state, according to APPLIA datathe Spanish Association of Appliance Manufacturers and Importers. Their turnover is 4.5 billion euros per year and they employ 8,000 people, modest figures for a state the size of Spain. They are, literally, low and hanging by a thread. what’s happening. In a word: relocation. Manufacturing outside the old continent is more profitable than doing so within, where the costs associated with production, regulatory and environmental costs are higher. More specifically, there is a star location: Asia. La Vanguardia collects the statements of Augusto Río, spokesperson for APPLIA and sales director of the German company BSH in Spain: “There are certain regulations in Europe aimed theoretically at improving the European industrial environment, but their application makes it more complicated to manufacture within the EU.” An example: the Carbon Border Adjustment Mechanism (CBAM) taxes the steel necessary for these appliances, but does not apply to imported appliances that arrive already finished. In other words, if you import a ton of steel from Asia, they charge you the tax. But if you use that same ton of steel in Asia to make an entire washing machine there and bring it to Europe, the washing machine enters without paying that green tax. Why is it important. The first consequence is direct and obvious: losing jobs. The not so obvious one is to become strategically dependent on third parties for essential domestic goods. Keeping these companies alive and operational supports local economies under a stable and quality employment model. At least, more than the precarious service sector that usually replaces it. From a technological point of view, the R&D&i ecosystem linked to the industrial fabric is broken: without factories, technical knowledge goes outside and feedback on innovation is lost. Paradoxically, the loss of these industries does not respond to a crisis in consumer demand: according to Renub Researchthe European home appliance market will go from 112.33 billion dollars in 2024 to 147.98 billion in 2033, an annual growth rate of more than 3%. But in this forecast report prepared by Mordor Intelligence We see that the quintet that leads the appliance market is the German BSH, the Swedish Electrolux, the British Dyson, the North American Whirpoool and the Chinese Haier. Precisely another Chinese brand, Midea, was the one that acquired the Teka Group between 2024 and 2025. Context. Historically, the manufacture of household appliances in Spain was a reflection of economic developmentalism and the adaptation of the “American Way of Life” to mass consumption in the mid-20th century. The families established a relationship that went beyond the purchase: they acquired the devices, but they also manufactured them, generating a strong bond and worker identity. I don’t remember one of my student apartments in Zaragoza where there wasn’t something by Balay. The globalization of the late 20th century and early 21st century put an end to it: multinationals moved their factories to countries with lower labor and environmental costs. Added to this context of relocation are specific legal asymmetries: Spain requires three years of guarantee of manufacturing compared to the two required by general EU regulations. Likewise, it is mandatory store spare parts for a decadewhich generates inventory costs that in practice the import avoids. Europe’s (only) great asset. To survive the fierce competition in the Asian market, the strategy of the European industry that is still resisting is to abandon the price war and differentiate itself in quality, as the German Mittelstand serves as an example. That is the plan of the CNA group, owner of the Cata brand and with a factory in Torelló. Santiago Torrent, its executive president, details: “The challenge is not to grow, but to do so with more added value” and that they must focus on quality, innovation, durability and better performance. This also includes after-sales and repairs, two areas in which the European Right to Repair Directive It requires them to have increasing responsibility for the product life cycle. Yes, but. The problem with this value-added strategy requires time, investment and a market that is willing to pay more for a European product, something that does not have to happen. And even less so in an inflationary scenario like the current one. On the other hand, China has already publicly shown its discontent with the protectionist European tariff measures, responding that he will take “the necessary actions.” And Europe’s dependence on China goes far beyond washing machines: it encompasses semiconductors, batteries and rare earths, structurally limiting how far Brussels can squeeze without harming itself.

We believed that air conditioning was the only way to beat the heat. A Mexican architect has been cooling houses with paint for decades

by

In 1973, during the oil crisismany countries suddenly discovered that cooling buildings had become an energetic luxury. Bioclimatic architecture then returned to the center of the debate and many looked to old solutions: patios, thick walls, shade and cross ventilation. Curiously, decades before, an architect had already built houses following that logic, obsessed with something that today sounds strangely modern: that a home should offer serenity and refuge from the aggressiveness of the outside. Heat also enters through the eyes. For decades we have assumed that fighting the heat at home involves a almost automatic gesture: lower blinds and turn on the air conditioning. It is a mechanical, direct and, above all, solution. face. Long before that became the norm, the architect Luis Barragan Another idea was already working in Mexico City: that the temperature of a house does not depend only on its degrees, but on how the body perceives it. Its architecture, built between pink, yellow, blue walls and dense shadows, had spent decades exploring something that neuroarchitecture is beginning to support today: color, light and matter. alter physical sensation of space. They don’t cool the air, but they can cool the experience. House-Workshop of Luis Barragán Barragán understood the importance of color. In the Barragán’s workcolor was never decoration. Studies on his architecture show that he treated it the same as a wall or a window: as a structural tool of perception. Its pink, ocher or blue surfaces were designed to react to changing light of the day, transforming the depth, closeness and visual temperature of the space. A pink wall under the intense Mexican sun seems to radiate heat, while a deep blue patio prolongs the feeling of sky and distance. That rrelationship between color and light It was a central part of his work. The architecture moved with the sun, and with it the sensation of the inhabitant also changed. House-Workshop of Luis Barragán The house as a sensory laboratory. His best example remains the Luis Barragán Studio Housebuilt in 1948 and today protected by UNESCO. There everything is designed to modulate the bodily experience: thick walls, closed patios, interior gardens, water, darkness and color. UNESCO stands out precisely that deep dialogue between light, space and matter as one of the great contributions of the 20th century. The house is almost a manifesto of how a home can appeal to all the senses at the same time. Barragán saw it as a living organism, constantly evolving, and in that organism comfort did not depend on technology, but on balance. nterior of the Gilardi House, in Mexico City The half light as a refuge. Barragan distrusted of modern glass architecture and total transparency. While much of the 20th century celebrated large windows and abundant light, he argued for the opposite: the “half light”. He believed that human beings need spaces with shade and darkness to rest, think and concentrate. He said that too much light generates anxiety. In their houses, the windows are reduced, hidden or filtered with colored glass. The light never enters all at once; is dosed. This decision not only changes the emotional atmosphere, it also reduces the thermal load and softens the visual harshness of summer. It is an old and simple solution, almost forgotten in many contemporary homes. Patio of Barragan’s studio house The colors of the weather. The famous Barragán palette It did not come from an abstract theory. Its colors were born of the Mexican landscape. The pink of the bougainvillea, the red of the tabachin, the violet of the jacarandas, the ocher of the earth and the blue of the sky. Everything was part of a natural continuity between architecture and environment. In fact, the call “Mexican pink”developed together with the artist Jesús Reyes, became one of his most recognizable signatures. That color, present at the entrance to his studio or in patios like those of the Gilardi Housegenerates a feeling of calm and depth that continues to surprise those who visit it. Its architecture demonstrates that color can be an emotional regulator of space. Eduardo Prieto Lopez House Tradition already knew this trick. In reality, Barragán did not invent all this from scratch. Much of his work includes centuries of vernacular architecture in Latin America. Painted stucco houses, interior patios, thick walls and breathable materials were part of a climatic logic before electricity. Stucco, for example, allowed the walls they will breathe better in hot climates. Painting them prevented the glare of the white surfaces under the harsh sun. In many places, color not only gave identity, it also helped to better inhabit the heat. Barragán took that tradition and brought it to modern language. San Cristobal block Science explains it. Yes, because recent studies about emotional architecture and embodied perception help put words to what Barragán intuited. Today we know that light regulates circadian rhythms, affects mood and modifies thermal perception. We also know that certain colors can make a room feel cooler or warmer without changing its real temperature. The body first processes a sensory impression and then translates it into comfort or discomfort. Barragán worked precisely on that point. He designed spaces where perception and physiology intersected. An old idea for a new problem. Thus, in the era of air conditioning and skyrocketing thermometers, when cities overheat and energy consumption skyrockets every summer, Barragán’s architecture returns to read with other eyes. Their houses remind us that cooling does not always mean cooling the air. Sometimes means control the light, tame the shadow, reduce glass, use appropriate materials and choose a color well. Are slow solutionssilent and long before modern domestic technology. In that sense, his work seems less like an aesthetic relic and more like an open conversation with the present.

Jaén was the largest producer of lead in the world. Decades later, he wants to repeat the game with rare earths, but he has a problem: reality

by

Somewhere between Linares and La Carolina there is a rusty derrick: the iron skeleton of what was, at the end of the 19th century, the largest producer of lead in the world. It is, obviously, the past, but in recent years many are completely obsessed with it being also the future. We have the latest example of this about 80 kilometers north of that derrick. There, in Aldeaquemada, an Australian company has just extracted a drill core and to announce that it is “a high quality area”. The question that hovers over Jaén these months is not whether there are minerals under its feet. We all know that. The question is whether all this dance of prospecting that we are seeing is something real or is it simply the expression of the desire of a province that continues to associate its ‘golden age’ with mining. What is happening? The last episode, as I say, stars Osmond Resources. In the SOR-08 survey has cut more ore than expected north of the province. We are talking about a project that covers 756 mining units between Aldeaquemada and Santiesteban del Puerto and search “titanium, zirconium, hafnium and rare earths” trapped in quartzites that hundreds of millions of years ago were beach sand. The ad has a trick, yes. What they have announced is a confirmation ‘during’ drilling. Laboratory analyzes (those that count) will take weeks. But, in reality, that is not what interests us. It is enough to do a small search on the internet to confirm that Jaén entire is being drilled with passion and enthusiasm for months now. And where does all that enthusiasm come from? In principle, three relatively independent engines. The first is geopolitical: in 2024, the European Union pressed the accelerator on ‘mineral sovereignty’ and approved a regulation on critical raw materials. The idea was to ensure that the extraction, processing and recycling of strategic raw materials carried out in Europe cover respectively 10%, 40% and 25% of EU demand. A project like Orión, oriented towards rare earths, is typical of something that in Europe (and in Madrid) sounds like glory. The thing about Madridor it is rhetorical. Just a couple of months ago, the Government approved a raw materials plan of 414 million euros which includes the largest mining prospecting campaign in Spain in more than half a century. Sierra Morena is expressly cited in it. Sara Aagesen he came to say that “with all certainty” rare earths will appear in the country. And then there’s the bag… That is the third engine. Companies like Osmond Resources live off the deposits, yes; but above all they live off the news cycle. After all, its market capitalization depends more on the ‘media battle’ than on the final results. In a field as complex as mining, failure is almost a given. And why is it important? Because behind all this noise there are a lot of small, aging towns those who are sold a new future. The mayor of Aldeaquemada It didn’t take long to celebrate Osmond’s results as a way to “generate jobs and wealth.” But the reality is that the Most exploration projects never produce. The energy transition has served as an alibi to look underground again, but the sector has changed so much that for the vast majority of actors, expectations are beginning to be more useful than reality. And that, in Empty Spain, is an existential problem.
