We humans like beer. The big question is whether we like it enough to have invented agriculture

The big question is not whether it was the chicken or the egg first, but rather what our ancestors began to make first: bread or beer? Does about 12,000 years We humans promote one of the most important chapters in our history in the Middle East, the Neolithic Revolution. From being nomads who lived by hunting and gathering, we became sedentary creatures who cultivated the fields. The change was so momentous that anthropologists have long wondered what caused it. It would be reasonable to think that the search for something as simple as bread, but there are those who believe that the answer is another: beer. What if the great catalyst that led us to plow and harvest the fields was not the search for bread but our ancestral hobby to raise your elbow? Cereals, what do I want you for? Scientists have spent the last few decades unraveling the mysteries from our most remote past, but there is one (fundamental) one that they have not yet agreed on: What the hell led humanity to change hunting and gathering for a sedentary life based on agriculture and livestock? What was the catalyst for the Neolithic Revolution, one of the most momentous periods of all time? Since since humans have been human, they need to eat, the answer seems simple: if those men and women settled to plant wheat and barley, it had to be to make bread, right? That is, they began to spend hours and hours tending their fields to obtain grain with which to nourish themselves. In the 50s however a question began to creep into the anthropological debate: What if what really interested them in grain was not bread or porridge but beer? But… And why is that? The debate is not new. It has been on the table for some time and is heated from time to time with new discoveries, such as the one announced in 2018 by a group of Stanford researchers who found “the oldest record of alcohol”, clues that tell us about the manufacture of beer ago 13,000 years. The last one to raise the discussion was Michael Marshall, a scientific journalist and columnist for New Scientist. In December he published a wide chronicle in which he reviews the latest findings on the subject and (most importantly) exposes how much it is costing anthropologists to reach a conclusion. The benefits of beer. To understand the discussion, we must first clarify a key point: neither the bread nor the beer of the Stone Age were like the bread and beer that we know today. The latter in fact has little or nothing to do with the refreshing amber liquid that they serve us in bars. It was more like a puree, a “sweet, slightly fermented porridge,” clarify Professor Jiajing Wang, from Dartmouth College in New Hampshire. “They germinated the grains, cooked them and then used wild yeast.” The result was a nutritious, caloric, protein-rich concoction that could even be safer than drinking water from rivers and wells. After all, it was the result of fermentation. Added to that was its alcohol content, a “social lubricant” that we still use in the 21st century to relax and socialize. Archaeologist Brin Hayden highlights, for example, its use in events that helped structure communities. There is research which suggest that (at least some communities) used it in rituals and for veneration of the deceased. Much more than suspicions. If the debate has been on the table since the 1950s, it is basically because it has been nourished by archaeological findings. Researchers have found traces that tell us about beer brewing at least 5,000 years ago in southern egypt and northern china or how he does 10,000 years Shangshan culture They brewed rice beer. One of the most important revelations in recent years, however, was the one achieved in a cave in Israel in 2018 by a team led by Professor Li Liu, from Stanford University. There they found evidence of beer brewing before the first cereals cultivated in the Middle East. The finding is related to the Natufiansa town dedicated to gathering and hunting, although they also tended to stay for long periods in the same place. “The oldest”. After analyzing residues located in 13,000-year-old mortars located in a cave in Raqefet, a Natufian cemetery near Haifa, Liu and his colleagues discovered remains of beer. Quite a milestone, like she herself stands out: “It is the oldest record of alcohol made by man.” “This discovery indicates that alcohol production was not necessarily a result of agricultural surplus production, but was developed for ritual and spiritual purposes, at least to some extent, before agriculture.” Issue settled? At all. To understand the complexity of the subject, it helps to review the discovery announced in 2018. At least at that time, the oldest known remains of bread, extracted from a Natufian site located east of Jordan, had between 11,600 and 14,600 years old. The traces of beer discovered by Liu’s team move in a similar range: a priori, they could be dated between 11,700 and 13,700 years ago. One of the keys to the problem, explains Marshall in your articleis that basically the making of bread and beer leaves very similar traces, basically starch residues. “We still don’t have conclusive evidence to answer that question,” Liu recognizes on the question of whether we turned to beer or bread first. The reality is more complex: because we don’t know, we don’t even know if some of those foods were the great catalyst that led our ancestors to change their lifestyle. “I wouldn’t be surprised if both were the motivations.” At the end of the day, the ‘beer first, bread first’ debate does not seek definitive conclusions so much as vindicating the weight of both foods. Both beer and bread, bread and beer, played a decisive role in diets and rituals.

seven essential pillars to beat the US

That the power that dominates AI has many roles in dictating the rules of the game at a global level is an open secret. China knows this and has stepped on the accelerator by putting on the table an ambitious plan for 2027 that concerns absolutely all key sectors. Your goal? Being able to securely and reliably provide key AI technologies that are deeply and high-level integrated into a new era of industrialization. Towards the global forefront. The plan is called “Opinions on the implementation of the special action Artificial Intelligence + Manufacturing“, has 2027 as a deadline and a maximum aspiration: that both its artificial intelligence industry and its application at an industrial level are at the global forefront, promoting what they call “new quality productive forces.” To get an idea of ​​its relevance and transversality, it is signed by eight government departments, including the Ministry of Industry and Information Technology, the Cyberspace Administration of China and the National Development and Reform Commission. The seven essential pillars. If there is something that stands out about the program, it is how concrete and detailed it is when it comes to materializing it. Thus, the seven key tasks are: laying the foundation through innovation, AI-driven improvements, product advancements, development of key actors, strengthening the ecosystem, ensuring security and international cooperation. Breaking down how, these are some of the measures to apply: Software and hardware innovation: coordinate the development of AI chips with the necessary software. Integration into production: Introduce AI models into core manufacturing processes, not just administrative tasks. Robotics and machinery: Accelerate the use of AI in industrial robots and machine tools. Open Ecosystem: Build a world-leading open source community. Security: develop technologies to protect algorithms and training data of industrial models. Some dizzying goals in less than two years. And if your measures are concrete, the objectives for the deep application of AI even more so: Large models: Deploy three to five general-purpose AI models for manufacturing, plus specific models for key industries. Data: Creation of 100 high-quality industrial data sets Real use cases: Promote 500 real case application scenarios in factories. Companies: promote two or three leading global companies in the AI ​​ecosystem, seeking strategic concentration of resources and leadership, along OpenAI or DeepSeek. Likewise, it wants to select a thousand model companies among specialized SMEs to support them. Sovereignty and leadership. In conclusion, what China has proposed is a comprehensive roadmap for the Asian giant not only to consume AI, but for its industrial sector to be the basis of technological development to ensure its technical independence in chips and algorithms before the end of the decade.

This is the city that linked China with the Mediterranean that one day an earthquake hid from the world

If there is a historical myth in archeology, it is finding the lost city of Atlantis. However, throughout history a few have been found: from that of Thonis-Heracleion in Egypt to the Greek of Pavlopetri passing through Port Royal in Jamaica. None are Atlantis (in fact, for numerous historians and scientists It’s more of a philosophical allegory of Plato than something real), but the last city that has just been found, far from typical places like the Atlantic, has quite a few similarities. Of course, it is in a lake in Kyrgyzstan. The lost city of Issyk-Kul. More specifically, it was in the northwestern waters of Lake Issyk-Kul that an international archaeological expedition organized by the Russian Geographical Society (RGS), the Institute of Archeology of the Russian Academy of Sciences (RAS) and the Institute of History, Archeology and Ethnology of the National Academy of Sciences of the Kyrgyz Republic stumbled upon Toru-Aygyr, as reports the news of the SGR. For the investigation they used underwater drones and high-precision diving. The legends were true. Around the Issyk-Kul lake run several popular legends about its formation submerging a city that already existed, something that was historically reinforced by the local rumor that when the weather is good and the water is calm, remains of the city can be seen. Likewise, within the Catalan Atlas of the Mallorcan cartographer Cresques Abraham it is recorded on a map the existence of a monastery where were the remains of San Mateo. This lake has been one of the obsessions of the historian and archaeologist Vladimir Ploskikh, behind the aforementioned discovery. Satellite view from 1992. Wikimedia But what a lake. Issyk-Kul is a truly fascinating lake without having to resort to myths: its name in Russian and Kyrgyz is “hot lake” and it has merit being 1,609 meters high. The secret is How deep it is (average 270 meters, maximum 702 meters), it is slightly salty and subsoil geothermal activity. Is the second largest alpine lake in the worldonly surpassed by Titicaca and one of its peculiarities is its transparency: its visibility is such that it can be seen up to 20 meters deep in favorable conditions. The icing on the cake is that there is evidence that there the black plague began. Vilya Shoni,. Wikimedia A most advanced city. Finding a submerged city is not unusual, but among the peculiarities of Toru-Aygyr is that its ruins are in shallow waters and the good state of conservation of its constructions, with solid stone structures, clay bricks and even wooden beams. In addition, they reveal that it was an advanced infrastructure, with public buildings, brick homes and irrigation systems. More specifically, they identified remains from a medieval cemetery, large ceramic containers, pieces of a mill, an architectural element that points to the decoration of a building such as a mosque, a bath or a madrasa. After checking with archival materials, the team confirmed that they were looking at a city that handled silk, spices and metals in the transfer of these goods between China and the Mediterranean from the 2nd century BC to the mid-15th century. Stick with the final date, we’ll come back to it later. Elizaveta Romashkina. Russian Geographical Society. It is the missing link of the silk road. As concludes researcher at the Institute of History, Archeology and Ethnology of the National Academy of Sciences of Kyrgyzstan and head of the Kyrgyz expedition, Valery Kolchenko: “The monument we are studying is a city or a large commercial agglomeration located on one of the key sections of the Silk Road.” During the investigation, they found a second site corresponding to a Muslim necropolis from the 13th–14th centuries that still preserves vestiges of traditional Islamic rituals, a third with remains of medieval ceramics, a large entire vessel (khum) and more burials. Finally, a fourth location located in the western part, of which remains of structures remain. The team’s idea is to return to continue analyzing everything, but for now the remains already say a lot about the relevance of the enclave, which Chinese historical sources record, such as explains the head of the expedition, Maksim Menshikov. Why did it sink? aka the Pompeii effect. The presence of large ceramic vessels and millstones in their original positions reveals that the city was abandoned abruptly, without subsequent looting. Kolchenko clears us of doubts: it was an earthquake. “At the beginning of the 15th century, as a result of a terrible earthquake, the city was submerged under the waters of the lake. According to our assessment, at the time of the disaster the inhabitants had already abandoned the settlement. The tragedy can be compared to the story of Pompeii, although it is much less known to the general public.” After the earthquake, he explains that the region’s population drastically changed how they lived, going from a prosperous medieval urban civilization to nomads. This large earthquake caused the lake’s water level to suddenly rise, swallowing the city. The water enveloped the city in mud and sand, protecting it from erosion and exposure to oxygen. It is not Atlantis nor does it need to be. It goes without saying that Toru-Aygyr is not the mythical Atlantis, but comparing it is inevitable due to the legends that surround it, the records that remain of its existence over the centuries in different civilizations and of course, the large amount of treasures found and its prosperity: there lived an advanced, rich and living city that disappeared one day under the waters.

There is an acute shortage of housing supply in Spain. So the convents of Toledo have seen an opportunity

Toledo has had an idea to reinforce the meager housing supply in its historic center. In the city there is the curious contradiction that there is demand for flats for rent while around 150 buildings of the monumental area (both public and private) remain closed and without tenants, so… Why not solve both problems at once? With that philosophy as a backdrop, two convents in Toledo are preparing to become landlords and allocate part of their buildings to rent. The historic center sees its housing offer expand (although still timidly) and in the process the religious orders obtain a new source of income. Quite a ‘win-win’. What has happened? That in Toledo they want to kill several birds with one stone. For some time now, its historic center has faced three challenges that, although at first glance they seem to have little to do with each other, are directly related. The first is the shortage of residential rentals. In Idealista, just over a few are announced right now. 50 apartments for lease and many of them do so as seasonal rentals. For long stays the offer is only 33. The second challenge is represented by abandoned buildings. Last year, the Consortium of the City of Toledo did the math and found that in that same area of ​​the Castilian-La Mancha capital, 150 buildings unused, some in ruins. The third challenge is not so much the city itself but the religious orders that live there: How to achieve income in the 21st century? Where to get money to pay bills or unforeseen events such as repairing the roof of the Discalced Carmelites convent, sunk during a DANA in 2023? Connecting the dots. The Toledo Consortium has come to the conclusion that these three challenges can be connected and has had an idea: to renovate wasted spaces in convents in the city to convert them into homes. And not just any type of housing. Their objective is to move them to the long-term rental market, the one that has the most difficulties in the historic center and more pressured It is seen through tourism. For that purpose, in November The organization gave the green light to the tender for the renovation of two properties: one located in the convent of the Discalced Carmelites and the other in the Immaculate Conception (Nasturtiums). Between them there will be four homes. “New opportunities”. The objective, explains the manager of the Consortium, Jesús Corroto, is to advance in the recovery of the disused heritage of the historic center and in the process generate “new residential opportunities”, especially for young people. The idea is to rehabilitate a building attached to the Discalced Carmelites convent with 131,000 euros to provide it with two new homes with a total constructed area of ​​130 m2. Investments will be made in the Capuchinas property. 130,000 euros to open two new residences in what was once the Priestly House, built at the end of the 16th century. In any case, the organization wants to go further and not stay in those four apartments. The SER chain indicates that it aspires to enable at least a dozen of housing and has already transferred more proposals to other convents. Whether they go ahead or not will basically depend on the budget and what the religious decide. After all, the buildings are private, non-segregable and considered BIC. The initiative would allow the creation between 20 and 30 housesto which other services can be added, such as parking. “Rental ethics”. In the case of the new homes set up in convents, a peculiar circumstance will occur: the Consortium is in charge of the works, but unlike what happens with other accommodation promoted by the Municipal Housing Company, its price will not be limited by a maximum limit. Since these are private properties, it is the religious who must decide what rents they charge to their future tenants, although Corroto already advances in The Country that a “rental ethic” will govern. What the organization he directs has done is put an inflexible condition on the friars and monks of Toledo: the new homes must be dedicated to residential rentals, not become tourist apartments, a business that has already attracted other religious of Spain who have seen the need to take advantage of their buildings. In Seville, for example, not long ago some cloistered nuns agreed to offer a part of their convent to tourists through Airbnb. The reason: selling candy is no longer enough to pay bills. Between 37 and 60 m2. In the case of Toledo, the objective is for the new homes to be available in about a year. To make it possible, the religious orders will assume part of the works and furniture. Once the project is completed, the city will have new apartments with a useful area of between 37 and 60 m2. The residences will have to comply with the regulations that govern the Historic Center of Toledo and will have between one and two rooms.

Quietly, Big Tech are ceasing to be exclusively technological companies to be something else: energy

Big technology companies not only compete for AI engineers. Now they also do it by energy profiles. And it is no wonder, because without the electricity that powers mammoth data centers necessary for AI tools to remain operational, the AI ​​race slows down. A bottleneck. AI has become the strategic axis of Big Tech, but its biggest bottleneck is no longer the talent around its systems, but access to energy. Data centers training and running larger and larger models consume massive amounts of electricityand guaranteeing that supply has become a business priority. According to account According to CNBC, with data collected by Workforce.ai, the hiring of energy-related profiles grew by 34% year-on-year in 2024. Numbers. As the media reports, a similar jump also occurred last year, with a level of energy profile hiring 30% above that of 2022, just before the explosion of generative AI after the launch of ChatGPT. The main reason is structural, since data centers represented approximately 1.5% of global electricity consumption in 2024, after growing 12% in five years, according to data of the International Energy Agency. Everything indicates that this demand will continue to increase as new AI infrastructure is deployed. What profiles are you looking for?n the Big Tech. According to stands out the middle, Technology companies are looking for much more operational positions: experts in energy purchasing, electricity markets, grid connection and energy strategy. CNBC reports that these positions are directly linked to ensuring real supply, not only to improving the environmental image of companies. Furthermore, not everything is about guaranteeing supply at any cost, but also about ensuring that electricity can be obtained in the most efficient way possible. Who is winning the talent war. Amazon and Microsoft lead in volume of energy signings from 2022, according to point the middle. Amazon has more than 600 additions (including AWS), while Microsoft has more than 570. In the case of the latter, in 2024 signed Carolina Dybeck Happe, former chief financial officer of General Electric, as chief operating officer, a gesture that many interpret as a strategic commitment to integrate energy and management on a large scale. Google, for its part, has accelerated in recent months with more than 300 hires, incorporating profiles from both large energy companies and the academic world. Between the lines. The strategy is not limited to hiring people. Big tech is also buying other companies. Alphabet, Google’s parent company, agreed the acquisition of data center company Intersect for about 4.75 billion dollars. At the same time, they outsource key phases such as the construction of infrastructure, relying on temporary contracts to manage projects, land and works. The clash with the traditional energy sector. The medium too points outthrough data provided by specialized consulting firms, that more and more senior energy infrastructure professionals are considering making the leap into technology, attracted by higher salaries and projects linked to data centers. The problem is that the most in-demand profiles, such as energy strategy or grid connection, were already scarce in the traditional and renewable energy sector. This has led to a tighter and more competitive talent market. Not everything is direct absorption. Some analysts also see opportunities for electricity companies. Travis Miller, energy and utilities analyst at Morningstar, explains to CNBC that the magnitude of the demand makes it unfeasible for Big Tech to do everything on their own. In many cases, they will rely on traditional public service groups to develop infrastructure and operate networks, which can translate into new revenue and employment in the sector. And now what. The border between technology and energy is being diluted in a very interesting way. Meta, Amazon, Google or Microsoft already sign long-term power purchase agreements, even with nuclear projectsand some have requested permits to trade electricity and sell surpluses to the grid. “There are technology companies that are becoming energy companies,” account Daniel Smart, CEO of The Green Recruitment Company, in the middle. Of course, for now, only to feed its own AI. Cover image | Microsoft In Xataka | AI is creating a new paradigm of success: products that everyone uses but have to close due to lack of income

It is a paradise for digital nomads

It is nothing new that Malaga city and Malaga province are magnificent places to spend your holidays, with towns such as Torremolinos, Fuengirola, Marbella, San Pedro de Alcántara, Benalmádena, Frigiliana, Nerja or Mijas as prominent tourist destinations of a lifetime. Now, Benarrabá probably does not appear in any ranking: it only has 452 inhabitants and has no coast, since it is in the heart of the Serranía de Ronda (another place worth visiting). Málaga city and Benarrabá are night and day. In the 21st century, the population statistics have the arrow pointing down. Currently, its population density is of 18.35 inhabitants per square kilometeralmost 100 times less than the 1516.69 inhabitants/km² of Malagathe provincial capital and an entire technological cluster within Spain: it is home to one of the leading AI companies within the EU (freepik), Total Virus and even Google has a center there. Between one municipality and another, 133 kilometers and approximately an hour and a half by car. To the nearest airports, (Gibraltar and Malaga), one hour and one hour and a half respectively. There is only one bus daily to larger municipalities such as Ronda or Algeciras. It is not that it is next to a big city (although the distances are relative) and it is well connected precisely. Obviously, there is also a huge difference in the price of housing. Due to its small size, Benarrabá makes it difficult to find rental data (there is none), but in terms of sales prices, it goes from 3,802 euros per square meter in the capital to €220/m² in the aforementioned town. according to Indomio data. Benarrabá is a coliving town. If we take a look at your economic statisticswe will see that sectors such as agriculture, transport, construction or hospitality appear, but no trace of tourism. However, in 2025 alone, this small municipality welcomed 52 digital nomads from more than 19 different countries, more than 10% of its census population. What does Benarrabá have to attract digital nomads?. An infrastructure that greatly simplifies the process of going to spend some time there knowing that you are going to find accommodation that is rented by the week (with prices ranging from 22 euros/day in a shared room and 35 euros/day for an individual), sociocultural activities and a hospitable neighborhood and spaces for teleworking with 1GB of symmetrical fiber, call rooms, good views and specialty coffee that can be accessed 24/7. What is Rooral?. In one word: Roorala coliving project that is defined as a rural activator and in which both the Benarrabá City Council and the local community participate. The idea is to partner to create a coliving and coworking experience in towns located in unpopulated areas to welcome those people who want to telework and integrate into the life of the municipality. According to La Opinión de Málagathe average stay of these teleworkers is 24 days. In that period of time, they revitalize the life of the municipality and revitalize the economy. Benarrabá is the first permanent base of the project and it is no coincidence. Juan Barbed, co-founder of Rooral, account how when his grandmother died and he had to return to town, he met numerous strangers who welcomed him with open arms. On the one hand, cities are full of stress and loneliness (not to mention sky-high prices), on the other, many towns in Spain are disappearing. He connected the dots to combat this imbalance: remote work. And it’s been three years now. Things to do in Benarrabá. Rooral You don’t have a town? Now yes. The co-founder explains for the Malaga environment that for those people accustomed to living in large cities, settling in Benarrabá is a surprising experience due to the closeness and human warmth: “An emotional bond is generated that is difficult to forget and the desire of many of them to return to Benarrabá in the future.” It marks some people so much that one of the artists who lived there has painted portraits of 45 neighbors, recorded a documentary and created a map of points of interest.

We know that the Earth has been hit by 80,000 meteorites. For some reason, most end up in Antarctica

If we look at the global statistics of finds of meteorites on our planet We may think that they are distributed homogeneously throughout the territory, but the reality is very different. Official data indicates that of the approximately 80,000 meteorites cataloged all over the world, more than 50,000 have been found in Antarctica… And this raises a big question: does Antarctica have something special about having so many meteorites? A contradiction. Although we talk about 60% of the meteorites that have been found on Earth come from Antarcticacollision theory tells us another. Specifically, physics, which tells us that meteorites fall randomly and uniformly throughout the planet, so Antarctica does not receive more impacts than the Sahara Desert or the Pacific Ocean. So… Why do we find so many meteorites on the frozen continent? The answer lies in a perfect combination of glaciologyvisual contrast and a natural “trap” that is now, ironically, being sabotaged by climate change. The conveyor belt theory. To understand why Antarctica is the great archive of the solar system, you have to understand how ice moves. And the secret is not in how the rocks fall, but in how the ice delivers them to humanity. To do this, we must go to glaciological models and studies from programs such as ANSMET, where they point out that Antarctica It is a real meteorite conveyor belt. The process. In this way, a meteorite when it falls inside the frozen continent buried deep in the ice sheet. Once here, the natural flow of the glaciers will push the ice that stores the rock inside from the center towards the coast. At certain points, the ice encounters barriers beneath the glaciers, such as hidden mountains that slow its flow and forces the ice to return to the surface. And this is where the famous katabatic winds come into play, which are truly fierce and dry with a force capable of eroding the upper layers of the ice from solid to gas. The result. It is what scientists call the ‘Meteorite Stranding Zone’ (MSZ) or blue ice areas. It is nothing more than the part of ice that has been worn away, but has not affected the rock it stored in any way. That is why over time, meteorites that fell thousands of years ago and traveled trapped in the depths of the ice now appear on the surface as if someone had put them there. A contrast trick. Logically, finding a meteorite among a pile of red ones can be somewhat complicated in our environment. But when we talk about a black rock on a white sheet like ice, the truth is that visually it is easy to find it. That is why this contrast is the best ally that meteorite searchers have. The preservation. But beyond the fact that finding a rock the size of a walnut in the middle of the jungle is a really complicated task, it must be taken into account that humid climates degrade the meteorite quickly. Something that does not happen in Antarctica, which is technically a polar desert. The dry environment it has acts like a real freezer which preserves the samples almost intact for millions of years. This allows scientists to recover not only the rock, but pristine information about the origins of the solar system. And that is why all these factors together make it more common to find more meteorites in this location than in others, and not because there is a predilection for falling here. An invisible threat. As pointed out a study published in Nature, we have a serious problem on the table: We are losing about 5,000 meteorites a year. Intuition would tell us that if the ice melts due to climate change, more rocks would emerge. But the opposite is true due to the thermal properties of the meteorites themselves. Being dark rocks (and many of them metallic with high thermal conductivity), they absorb solar radiation much more efficiently than the surrounding ice. Even at subzero temperatures, the rock heats up enough to melt the ice just below it. This causes the meteorite to sink and create a small pool of water that refreezes them, burying the rock out of sight of researchers or satellites. Thermal models suggest that this disproportionately affects iron meteorites, which are especially valuable for understanding planetary cores, causing us to have many more chondrite or rocky meteorites. Race against time. Humanity has so far managed to recover 23,000 meteorites, giving us a large cosmic library that allows us to better understand everything around us. The problem is that the clock is ticking, and the most important part of the archive is beginning to sink, so now the most important thing is to hurry up to get the most valuable meteorites for us.

Italy’s greatest fortune was forged in scarcity to become your forbidden pleasure: Nutella

Mayans, Olmecs and Aztecs They knew how to appreciate the value of cocoa, and that is why they used it as currency to buy goods and services long before Christopher Columbus. make those lands yours just by reaching them by boat more than 500 years ago. In fact, chocolate has become a “guilty pleasure” these days. so widespreadwe are (yes, I include myself) causing global shortages. Precisely, cocoa is the main ingredient of a product that made two brothers extremely rich in ruined post-World War II Italy: the Ferreros. From that scarcity emerged an empire with $19 billion in annual revenue and a presence in more than 170 countries. The challenge: create a chocolate bar without cocoa In the middle of World War II, Italy suffered an extreme shortage of many things, but especially cocoa, a problem that had already hit Europe during the time of Napoleon. As and as explained in The Green CompassIn 1806, Napoleon Bonaparte became involved in a geopolitical and commercial battle with his enemy the United Kingdom. This caused the volume of trade to reduce considerably, causing a shortage of overseas products. One of them was cocoa, of course. Given the shortage of the main ingredient, a master chocolatier from Turin He came up with the brilliant idea of ​​mixing the little chocolate he had left with a dough made from hazelnuts that were abundant in the area. In this way, it could offer a delicacy with a certain chocolate flavor, but using less cocoa in its production. This is how the gianduia or gianduja. Almost a century and a half later, in 1946, the brothers Pietro and Giovanni Ferrero They found themselves in the same cocoa shortage situation than his Turin colleague. If it had worked before, why wouldn’t it work a second time? Cioccolateria Ferrero in Alba The Ferrero brothers revived the old recipe for hazelnut paste with sugar and cocoa to survive, creating a spreadable bar that would lay the foundations for a product that today sweetens breakfasts and snacks around the world. ​This hazelnut paste and little cocoa saved the Cioccolateria Ferrero that Pietro ran in Alba, south of Turin and in the heart of the Piedmontese countryside. The product, in the form chocolate bar that could be rolled and spread on the bread that mothers gave to their hungry children quickly sold out in local stores. Giandidot by Ferrero Faced with unexpected success, Pietro and his brother Giovanni soon formalized their business, founding a company called Ferrero SpA and opening a small factory in Alba. While Giovanni focused on distribution, Pietro focused on overseeing the manufacturing of his flagship product. However, Pietro died in 1949 of a heart attack. His son Michele, who was 24 years old at the time, took over from his father at the head of the factory. Ferrero factory workers on a company bus Michele was not a businessman like his uncle Giovanni, nor did he have a university degree, but he did he had inherited his father’s creativityto whom affectionately They called “the scientist” and he was willing to improve the recipe for the product that was making them rich. In 1949, Michele made some changes to the formula of the gianduja to make it creamier and easier to spread. With this change, the Ferreros could differentiate themselves from other confectioners who also produced the traditional Piedmontese sweet. The “Supercrema” had just been born. According to what is collected in the book ‘Nutella World‘, the success of the Supercrema was such that the brand soon had the second largest fleet of trucks, only behind that of the army. In 1947, the company barely had a dozen distribution trucks, in 1950 they already had 154 and by 1960 there were more than 1,624 delivery trucks for their company. cocoa cream with hazelnuts. Ferrero Supercream Ad ​Birth of a star product: Nutella In 1964, a change in product labeling legislation banned the use of superlatives in brand names. That forced the Ferreros to change the name of their Supercrema. Given the success of Supercrema, the Ferreros were already thinking about the internationalization of the brand, so they used the English name of its main ingredient “Nut” and, after trying variants such as Nutsy, Nussly, Nutosa and Nutina, they finally decided to use the Latin suffix “-ella” to maintain its Italian roots. Nutella was born and its iconic glass jar with a wide mouth and flattened body. Its smooth texture and addictive flavor made it an immediate success throughout Europe, but Michele continued trying different recipes. The consolidation of Ferrero as the empire it is today occurred with the Kindergarten release in 1968, the “unexpected” Tic Tac mint candies in 1969 and Ferrero Rocher in 1982, coinciding with the opening of factories in several countries. Today, Ferrero generates $19 billion annually, maintains secret formulas and operates in 170 countries without being listed on the stock market. Ferrero established itself as world leader in hazelnut creamseven having its own World Nutella Day since 2007: February 5. Michele Ferrero died in 2015 at 89 years old, leaving a fortune estimated at more than 26.5 billion dollars which made him the richest man in Italy, but he had also continued to manage a large empire as a family business in which the relatives of his employees were hired. As and how I collected The Spanish“Hiring children of employees strengthened the bond of the community and united many of its men and women to the company throughout their working lives,” noted Salvatore Giannella, biographer of the businessman and author of ‘Michele Ferrero, share values ​​to create value’. Giovanni Ferrero, grandson of Pietro Ferrero, inherited the empire of cocoa and hazelnut cream, increasing the family heritage up to 40.8 billion dollars.

There is a Europe that is suffocating to pay for housing and another that lives in peace. And this map shows the differences

Beyond the political ups and downs, corruption, unemployment, the war in Ukraine, or the (increasingly) convulsive scenario of international geopolitics, from time to time The CIS reminds us that there is a much more everyday problem that keeps us Spaniards up at night: access to housing. At the end of 2025 39.9% of those surveyed by the organization pointed out housing as “the main problem” facing the country. And it is normal if you take into account the mismatch between supply and demand, the pressure that carries out tourist rentals and (above all) the sharp rise in prices of recent years. Every time we talk about the residential market, however, the same question arises: beyond the exact cost of the square meter (m2), calculated by the General Council of Notaries, the executive or portals like IdealisticHow “unaffordable” is accommodation in Spain? What economic effort does it require from families? Is it more or less than what other European households must assume? Getting perspective Type of housing (in m2) available spending 40% of monthly income. ESPON, the program who is dedicated to studying cohesion of the EU, has published a series of maps that help answer these questions in a quick, direct and, above all, visual way. To prepare them, two parameters have been basically set: the prices of the real estate market for sales and rentals and the income data published by Eurostat. Everything divided by regions. By crossing them the organism has been able to carry out two calculations. The first is to estimate what type of housing (in m2) a person who allocates 40% of their income to this purpose can rent in each EU region. The second is what percentage of their rent that same tenant should dedicate if they wanted a 100 m2 house. Percentage of monthly income necessary to rent a 100 m2 home. ESPON does not stop there. He has also transferred those same questions to the buying and selling market residential. That is, what type of housing could a person willing to invest 40% of their annual income for an entire decade afford? And how many years would you have to endure that same budgetary effort if you wanted to buy a 100 m2 apartment? In both cases the maps are similar and they leave behind a series of conclusions, such as the profound differences that exist within the same country. “Regions containing and surrounding capital cities such as Paris, Berlin, Lisbon and Madrid tend to be less affordable compared to the rest of the nation. Additionally, coastal regions tend to be less affordable, which is also clearly seen in the Netherlands and Germany, Portugal, Spain and France.” Available housing (m2) investing 40% of the income for 10 years. Years necessary to buy a 100 m2 home investing 40% of the income. For example, while a Madrid resident willing to invest 40% of his annual income in housing would need between 20 and 25 years To pay for a 100 m2 house, a resident of the province of Teruel would need at most ten years of effort. In Barcelona it would need around 20-25 years while on the other side of the peninsula, in Pontevedra, between 15 and 20 years would be enough. The worst part in Spain is Malaga, the Balearic Islands and the Canary Islands, where ESPON calculates that on average a buyer would need to invest 40% of their annual income for more than three and a half decades. A very similar effort would have to be endured by the inhabitants of the Algarve, Setúbal, part of the Paris area, Monaco, Corsica or different points spread across Eastern Europe, where ESPON itself recognizes that “quite unaffordable” areas are concentrated. If we talk about the rental market, the panorama It’s not very different. A Madrid resident who would like to rent a 100 m2 apartment would need to dedicate (on average) between 80 and 90% of their income to it. The situation is worse in coastal points, such as Barcelona, ​​Huelva, Malaga and Eastern European regions. In the provinces of Zamora or Huesca they would be enough between 30 and 40%which is closer to the debt ceiling level than recommend assuming the experts.
