China has invented the coldest helium-free alloy in the world. The American DARPA is not going to like it

In addition to having an extremely high voice, filling balloons or scuba diving, the most widespread use of helium is in refrigeration, a crucial task in countless tasks ranging from magnets for magnetic resonance imaging to particle accelerators (with conventional helium or Helium-4) to cryogenic cooling for quantum computing or neutron detectors (Helium -3). Critical industries. Because yes, everything is helium, but the circumstances change depending on the isotope. Thus, while Helium-4 is abundant in the atmosphere but difficult to retain (it escapes into the atmosphere due to its lightness), Helium-3 is scarce on Earth and is also difficult to obtain: it is a byproduct of the aging of tritium nuclear warheads. Simply put: the helium needed to cool quantum computers and cutting-edge physics acts as a bottleneck to research. A Chinese research team has published in Nature a solution: a metal alloy that cools almost to absolute zero without needing helium. The invention. It is a metallic alloy, EuCo₂Al₉ (ECA), a rare earth intermetallic compound capable of reaching 106 millikelvin (–273.05 °C), thus establishing a record: it is the lowest temperature achieved by a metallic magnetocaloric material without using helium-3. Another peculiarity is that it combines two seemingly antagonistic properties: it acts like a sponge that absorbs heat from the environment and its thermal conduction is between 50 and 100 times greater than other similar materials. A combination that postulates it to be the definitive supercoolant. The network structure, its interactions and the resulting supersolid spin state. Chinese Academy of Sciences Why is it important. We have already seen that helium-3 is a rare commodity and its usefulness in advanced physics and quantum computing. Finding an alternative opens the door to alleviating that bottleneck, although it is still in an early stage. Historically the largest global suppliers of helium-3 They have been the United States and Russiaas a byproduct of its nuclear programs. With this invention, China is one step closer to achieving independence of this strategic resource because it currently imports almost all of the helium-3 it consumes (95%, according to this paper 2024). But the United States is also interested: at the end of January, the Defense Advanced Research Projects Agency launched a call to develop a modular helium-3-free cooling system for quantum and defense technologies. In less than two weeks I had the solution, yes, from China. Context. The superconducting quantum computers They require working below 1 Kelvin and in that scenario the standard for decades has been dilution refrigeration technology. In a few words and in a simplified way: expensive refrigeration contraptions that occupy cubic meters and need helium-3 continuously. This limits its scalability, practically limiting it to specialized laboratories. Adiabatic demagnetization cooling on which the ECA is based is not new, in fact the concept is a century oldbut its features have never been up to par. As explains the CASthe endemic problem was its poor thermal conductivity. According to the South China Morning PostPeking University already built two refrigerators using this principle in 2024, which have been operational for several months. How have they done it. The cooling technique is called adiabatic demagnetization (ADR): a magnetic field is applied to the cold material, so that the internal “magnets” of the material align and release heat to the outside. When the magnetic field is removed, they return to their natural disordered state, absorbing heat from the surroundings, thereby lowering the temperature. To solve the historical problem of low conductivity, ECA enters an unusual “metallic spin supersolid” physical state, which combines high heat absorption capacity with thermal conductivity similar to a conventional metal. Yes, but. Being able to drop the temperature to 106 mK is remarkable, but the reality is that classic dilution systems in their most advanced version are capable of reaching 10 mK or less. And this is where much of quantum computing operates. In short: there is still a thermal gap to overcome. On the other hand, it is a first step: going from laboratory material and even a prototype to the industrial or military environment is a long road. Scalability and costs will be decisive. Finally, it should be noted that the composition of the ECA includes Europium (in addition to cobalt and aluminum), a rare earth that makes the operation difficult and expensive. Nevertheless, China starts from a privileged positionas long as it is the absolute leader in this industry.

After 10 years in prison for not revealing where 500 gold coins are, the world’s greatest treasure hunter is now free to go after them

Right off the bat, the name of Tommy Thompson It may not sound familiar to you at all. Besides ocean engineer and inventor, he is one of the greatest treasure hunters in the world, a profession that inevitably evokes Indiana Jones and a life of cinema. And well, Thompson has it: a few days ago he was released from prison after serving 10 years of his sentence. The crime? Do not reveal where 500 gold coins from a famous sunken ship are (among other things). The discovery. In 1988 Tommy Thompson and his team, the Columbus-America Discovery Group, they found the remains of the steamboat SS Central America at a depth of 8,000 feet in the Atlantic, about 200 miles east of Charleston, South Carolina. To achieve this, they used Bayesian search theory and a remotely operated vehicle. The SS Central America was known as the “Gold Ship” for something: how much gold it transported. How much? good question. The gold ship. To give some context, it was the time of the gold rush and the mission of the ship was to transport that valuable metal from the new San Francisco Mint to increase the reserves for the banks of the eastern United States. He never did. On September 3, 1857, while operating on the Panama route, it sank off the coast of South Carolina when it was involved in a category 2 hurricane. The ship carried 477 passengers, 101 crew members and much, much gold. In fact, its sinking was one of the triggers for the panic of 1857. I don’t have the accounts. Gary Kinder spent a decade studying the event to write his “Ship of Gold”, where details which was carrying 3 tons of gold and possibly a similar amount of passengers (undisclosed and therefore unquantifiable) and it was also rumored that there was another 15 tons of gold in a secret army shipment. However, a US Department of Defense document declassified in 1971 reported that the official cargo was 11.2 tons of gold (not including personal or secret gold). The American naval history magazine, the closest source to the discovery, It does not give a figure in weight but a value: The gold consigned to New York banks was equivalent to 40 million dollars at the time. In general, the figure of 30,000 pounds of gold (about 14,000 kg) is also relatively widespread. But what was on the boat is one thing and what they found is another. Or they said find. Bob Evans, chief scientist of the expedition (and another one that followed in 2014). from the hand of Odyssey), account for the Seattle Times that in 1988 they found two tons of gold. The legal conflict. Much of that gold was later sold to a trading company for about $50 million. as reported by Reuters. But according to those 161 investors who financed $12.7 million for the expedition, they never reaped the benefits. So In 2005 they filed a lawsuit for breach of contract and concealment of assets. Thompson first secluded himself in Florida, then disappeared and lived under a false identity. He was finally arrested in 2015. The case reached a dead end: the judge in the case ordered him to reveal the whereabouts of 500 missing gold coins, but the engineer He claimed not to know where they are. He was declared in contempt, which is why he has served a decade in prison. The liberation. Today Tommy Thompson is 73 years old and a few days ago regained his freedom because, according to the judge, keeping him imprisoned does not work. CBS News picks up the opinion of civil law experts who explain that it is very unusual for a sentence for civil contempt to last so long. He has neither revealed where the coins are nor has he settled the debt with his investors. Meanwhile, the treasure of the SS Central America continues to feed the myth: in 2022 was auctioned one of the largest bars on the ship, 866 ounces (almost 27 kg), reaching a price of 2.16 million dollars.

How to use artificial intelligence at Easter to help you organize your trip or your long weekend vacation

We are going to tell you several things in which AI can help you during Easter. This can range from prior preparations to some help once you are there. You already have at your disposal a large number of apps and websites to organize yourself during Holy Weekbut so much Claude as ChatGPT either Gemini They can also help you by fulfilling several of the functions of these apps, and having them all in one. You should know that these are just ideas on how to apply the artificial intelligence in travel planning, but You should not blindly trust anything they tell you.because they can make mistakes. However, there are some applications that are quite useful, and I must even tell you that I keep a couple of them to myself after having discovered them researching for the article. Ask me to help you choose your destination If you still don’t know where to go At Easter, even knowing that accommodation may already be full in many destinations, you can also ask the AI ​​to give you suggestions on where to go. Thus, depending on the parameters you give it, it will make suggestions that adapt to what you have in mind. To do this, you have to create a prompt in which you give him some notions of what9 you want. You can tell it if you want the beach, mountains or city, if you are traveling alone, as a couple or as a family, and how many days you have available. You can also give him ideas about your budget.and ask him to give you several suggestions explaining the reason for each one. You can use a prompt like this: “I want to go on an Easter vacation from April 3 to 6, we are two adults, we like cities with history but that are not overcrowded, we have a medium-low budget and we leave from Valencia. What destinations would you recommend?” Create a day-by-day itinerary Once you have chosen the destination you want to go to, artificial intelligence can also help you create a complete day-by-day itinerarysuggesting and organizing the most recommended visits in a logical manner, and with more or less adjusted times. This is something that can always take a lot of time to do by hand, and even if you don’t want to trust 100% of what the AI ​​tells you, it can serve as a starting point that you can later adapt. You can use a prompt like this: “I’m going to spend 4 days in Seville from April 3 to 6. We are two people, we are interested in architecture, gastronomy and historic neighborhoods, but we want to avoid long lines and the most touristy sites. Can you make me a day-by-day itinerary with morning, afternoon and night?” Claude has a route planner Some AIs have their own route planning system. For example, you can plan routes with Claude with an internal mechanism that asks you several questions to find out what you want. This mechanism works for you to plan new routes and create a map module from an already created one. For example, if you have created a four-day route, then you only have to write the following: “Group everything in one map module” When you do this, a map module will be generated within Claude, with tabs for each of the days and a list of places you plan to go. These sites will be linked on the map so you know where to go from, and you can open the route in Google Maps. Create specialized AI You have two very good alternatives to create an AI specialized in the destination using only the documents that you give him as a knowledge base. The best of them is use NotebookLMbecause in addition to uploading PDFs and other files you can also add YouTube videos or websites as sources from which you will get the information. You can also use Claude. The advantage in both cases is that have control of the fonts you usebeing able to add travel guides that you trust to the sources, or official websites where all the first-hand information is available. Ask him to make your suitcase list I must admit that I am terrible at organizing my suitcase, and this is something that AI can also help you with. You can ask him to creates a list of things to take which will be personalized depending on your destination, the duration of the trip and the activities you are going to do. You can use a prompt like this: “I’m going to spend 5 days on the Costa Brava during Easter. There will be some hiking, trips to the beach if the weather is good and some dinner at a restaurant. Can you make me a complete packing list, including clothes, shoes, toiletries and various items?” In case you decide to use Claude, since he can make you a interactive packing list with a check list so that you can complete all the items you have included and know which ones you are missing. If you prefer you can also dictate to the AI ​​the things you want to have on your list of luggage, so that it is personalized. Then, when something else occurs to you, you can go to the chat you have with the AI ​​for this and ask it to add or remove items, or even ask it if you are missing something considering when and where you are going. Gemini finds flights for you and compares prices Although all AI chatbots can help you search for flights, Gemini integrates Google Flights along with the rest of Google tools. That makes the search engine company’s AI the best alternative to search for flights and give you all the information about prices and availability. To use this function you can ask directly for flight options from your city of origin to your destination by specifying the dates, and the … Read more

the European recipe to save the wine crisis

Touring La Rioja in autumn is to enter an impressive sea of ​​color in the form of small yellow, orange and red trees. However, this characteristic bucolic landscape will change in the coming years following Europe’s plan: uproot vineyards. Paradoxically, from the same place from which they have been receiving funds for decades to promote the expansion of the sector. The EU Wine package. It is Europe’s roadmap to manage the crisis that the sector is going through and was agreed in December 2025. How? Going from expansion to contraction of supply administratively. Thus, it favors the destruction of productive vineyards definitively and voluntarily with incentives. In addition, the plantation system is made more flexible, extending deadlines and exempting from fines those who decide not to use their plantation authorizations. On a commercial level, Brussels is committed to modernization and added value over volume, consolidating alternatives such as non-alcoholic wines and digital labeling with QR codes. Why it is important. To begin with, due to the economic magnitude of the sector in the EU and what these definitive goodbyes imply: it supports 2.9 million jobs and contributes more than 130,000 million euros to the community GDP, according to the report “Economic, social and environmental importance of the wine sector in the EU” by the European Wine Business Committee prepared by PwC. Rioja has recently opened the aid application deadline and offers between 2,300-2,600 euros per hectare. But also because the EU plan involves applying the same measures for different realities. By not distinguishing between regions with large surpluses (Bordeaux) and areas with more balanced markets (such as Rioja or Duero), there is a risk of destroying agricultural capital of incalculable value. The drama is not that about “bad wine”, but that the market can no longer absorb even wines with Designation of Origin. Context. For decadesthe Common Agricultural Policy subsidized vineyards by protecting minimum prices, which distanced the farmer from a market reality in which supply exceeded demand. This approach generated large structural surpluses: since the 80s There is the term “wine lake” to refer to that overproduction derived from central planning that ignored the change in consumer habits. We drink less and less wine and The new generations are not so interested. Nevertheless, Spain more or less holds the type although it is not immune to changing habits: people drink less frequently and more selectively and the alcohol-free options. Europe tried some patchesbut the wine package is the current and most drastic response to the problem that the agrarian policy itself created. Evolution of global wine consumption. Source: International Organization of Wine and Vine La Rioja, ground zero. La Rioja has already made a move opening the aid period for the green harvesta first step that this year seeks to identify those who are willing, in the near future, to say goodbye definitively to their vines. What is “Green Harvest”? Destroy the grapes before they ripen. There is a key nuance: 15 extra points are awarded to those who commit to uprooting their vines forever in the future. The impact of the measure. The consequences of this plan are measured in terms of feasibility and territory: On an economic level, while the green harvest is paid between 2,300 and 2,600 euros per hectare, the definitive grubbing is estimated between 4,000 and 6,000 euros/hectare (in France). In any case, the basis of the aid seeks to reach the professional whose income depends exclusively on the countryside, trying to avoid the collapse of the rural economy (for example, in Rioja). Loss of assets. The uprooting destroys irreversible agricultural capital. In areas where there is no alternative or the sector’s roots are deep, such as La Rioja (honoring the slogan: the land with a wine name), it can be a catalyst for the abandonment of the territory and a change in its landscape. Towards a luxury wine. Or a wine without. The sector is moving towards a model of less and more, a shift towards adding value to the product. In short, the wine that remains on the market is scarcer and can defend higher prices. Likewise, its survival depends on accepting that wine is no longer a mass consumption product, but rather a value-added good adapted to new trends.

is ceasing to be the ‘Chinese Samsung’ to be something more similar to ‘the Chinese Apple with a car’

Xiaomi’s 2025 has been a record in several aspects, but also the certification of something that we had been seeing coming for a long time: the end of the Xiaomi that we knew. And it gives way to a new, much more interesting Xiaomi. Why is it important. For years, Xiaomi was the company that made the margins of Apple and Samsung a war to fight. His promise was, above all, the price. Now, for the first time in its history, the smartphone segment has decreased by 2.8% in revenue while the electric car and AI segment has grown by 224%. The company that built its identity on bargain He has started talking about something else. The panoramic. Total revenue in 2025 exceeded 450 billion yuan (about 57.7 billion euros), 25% more than the previous year and the first time that the company has surpassed the 400 billion barrier. Adjusted net profit reached 39.2 billion yuan (about 4.95 billion euros), an all-time high. But the real headline is in the composition of that revenue: a year ago, the smartphone and IoT device business represented 91% of the total. It has now fallen to 76.8%. Fourteen percentage points in a single year is too abrupt a drop not to assume that we are facing a different scenario. Between the lines. The segment that Xiaomi calls “smart electric vehicle, AI and other new initiatives” has achieved its first year with positive operating profit: 900 million yuan (about 114 million euros). The figure seems modest, but in reality it hides an intentionally opaque financial architecture. That same segment has increased its operating expenses by 87.7% year-on-year, to 24.8 billion yuan. Included are the costs of the car, but also the billion-parameter MiMo language modela robotics program, the development of own chips and the AI ​​agent platform Xiaomi miclaw. That is to say: the profits from the car are financing the company’s AI bet. And in 2026 that balance could be broken: Xiaomi has committed 16,000 million yuan (about 2,020 million euros) only in AI and “embodied intelligence” this year, part of a three-year plan of 60,000 million. The contrast. While the car moves forward, the phone moves backwards. The gross margin of the smartphone segment has fallen from 12.6% in 2024 to 10.9% in 2025, and in the fourth quarter it plummeted to 8.3%. The reason is the memory crisis: the demand for AI data centers has generated a bullish supercycle in DRAM and NAND prices which is swallowing the profitability of any mobile manufacturer. In the end, the same AI boom that Xiaomi is trying to capitalize on is what is eroding its core business. The company that financed its expansion based on tight margins in mobile phones now discovers that those margins are unsustainable precisely because of the trend it wants to lead. For years, the label that best defined Xiaomi was “the Chinese Samsung”: a company with a very wide range of products, presence in all price segments and a business model built on volume. Now the accounts point in another direction. The growing weight of the ecosystem of services on a base of premium hardware, the car as an aspirational extension of the brand and the own AI models integrated into all devices draw something more similar to Apple: a closed ecosystem where the hardware is the gateway and the services are the margin. The CEO of Ford already drew this parallel. With the difference that Xiaomi also makes the car. Apple doesn’t do that. The context. This shift has not come overnight. We have been seeing for years how Xiaomi patiently built its premium jump, first with Leica cameras, then with a SU7 that aimed directly at Tesla and Porsche. What the 2025 results confirm is that this repositioning is no longer a declaration of future intentions: it is the present financial reality of the company. One detail: 60% of buyers of the SU7 They are iPhone users, a sign that Xiaomi is capturing the consumer who pays for ecosystems, not specifications. The big question. Can a single company simultaneously maintain an under-pressure smartphone business, scale an electric car operation with some fiscal uncertainty, and fund an AI program with indefinite to delayed returns? The 754 million monthly active users and the 1,080 million connected IoT devices that Xiaomi has are an argument for optimism, but maintaining three demanding fronts at the same time, with the business that finances them under siege, is the great challenge that Xiaomi has ahead of it for this new stage.

We know its price and even its name from the most expensive mansion in Spain. The only thing we don’t know is who sells it.

In Sierra Blanca, the urbanization most exclusive in Marbellawalls do not only delimit properties. They are also silent. It is the unwritten rule of Spanish luxury. The most expensive mansion of the country has just gone on sale with 5,600 square meters of luxuries and opulencewhich does not lack a fountain inspired by the Bellagio casino in Las Vegas. His sale price It is 70 million euros and has absolutely everything, except the answer to the most obvious question: who is selling it? ELON MUSK VS JEFF BEZOS: STAR WARS An oasis of luxury overlooking the Mediterranean As and as highlighted ForbesSierra Blanca is one of the most exclusive urbanizations in Spain and a natural fortress for privacy. Nestled on the slope of the mountain range that gives it its name is Villa Bellagio. The impressive mansion sits on a plot of 14,000 m2 300 meters above sea level. Its gardens mix palm trees, cypresses and native species in a setting designed both for beauty and to keep its tenants out of reach. of curious looks. The 22-meter infinity pool seems to extend to the horizon, with spectacular views over the Mediterranean. A fountain, a replica of the one at the Bellagio hotel-casino in Las Vegas, greets visitors before they even cross the door. The façade, designed by the Spanish architect Jesús del Valle, is impressive with a double staircase flanked by 20 columns up to eight meters high. Engel & Völkers In fact, the house is so ostentatious that it even caught the attention of YouTuber Ibai Llanos, who dedicated it to one of his videos in which he went through it it already showed its details. The mansion was built by Joe Ricotta, founder of a logistics company in the United Kingdom and a luxury real estate developer in Spain. According to the local pressRicotta sold the property (at that time called Villa Ricotta) in 2021. for 40 million euros. However, no one knows the identity of the current owner, faithful to the tradition of discretion that prevails among the residents of the most exclusive urbanization in Spain. Thirteen suites and no random details The interior of the mansion does not disappoint those who arrive expecting opulence and luxury in abundance. The 5,600 m2 built of the mansion are distributed in thirteen suites between its two floors: four of 40 m2 each on the ground floor and eight of up to 50 m2 each on the upper floor. Engel & Völkers Each of the suites has large windows with direct views of the Mediterranean and its own marble-clad bathroom. In total, no less than 24 bathrooms spread throughout the house. The main living room exceeds 200 m2 and connects with a dining room for 14 people and an impressive 60 m2 kitchen with state-of-the-art appliances. Engel & Völkers During his visit to the spectacular mansion, Ibai discovered that the entire house had a centralized home automation system from which the lighting, climate, blinds and sound are controlled in every corner of the house. An in-house electricity generator and several independent water tanks ensure that nothing ever fails, turning the lavish mansion into a self-sustaining bunker. The lower floor is the best example that Villa Bellagio is not a conventional luxury mansion and falls into another category. The spa area includes a heated indoor pool, haman, Finnish sauna, massage room and full gym. Engel & Völkers The leisure offer of the mansion includes a private cinema with capacity for 22 spectators, a double bowling alley of professional sizes, a billiard room with its own bar and a hairdressing and manicure salon for exclusive use. For motor lovers, the mansion reserves its most extravagant chapter: an air-conditioned gallery where to exhibit a collection of up to 12 vehicles as if they were museum pieces, with lighting designed to highlight every detail of their bodies. Underground, a second garage accommodates 40 more cars. In total, 52 places of parking for a collection which, in this context, no one would consider excessive. Engel & Völkers Concierge, cleaning and maintenance services with five-star hotel standards complete the proposal that, more than a home, functions as a private resort. All this behind walls that, as tradition dictates in Sierra Blanca, they reveal nothing about who lives (or has lived) on the other side of the luxurious entrance gate.

those who follow this Japanese custom and clean less at home and those who do not

Everyone does what they want at home, but there are habits that are better than others and customs that, although you may like them more or less individually, may be a cultural custom specific to your region. Without going any further, there is one that raises blisters and that no one is completely clear about: take off your shoes when entering the house. Without going any further, the map that you see below these lines and crowning the article is from Wikimedia: in green, the states that take off their shoes when they get home and in blue, those that do not. We tend to associate this habit with Japan and although it is probably the best-known country where it is applied, it is not the only one. Essentially almost all of Asia takes off its shoes, also North Africa and Canada. The latest Wikimedia map on Which countries take off their shoes at home and which don’t In fact, custom is multicultural and independent. Thus, in Japan they even have an area of ​​the house set up for this purpose, the genkanwith a step called agari kamachi where the sacred limit is established between the “outer world” (dirty) and the “inner world” (clean), as the digital media Nippon explains. In Nordic countries the custom is more related to the weather: moving around the house with shoes full of mud or snow does not seem like the best idea. In the Middle East, the origin points to religion. Without going any further, the Quran has some verses like this from Allah to Moses: “I am your Lord; take off your sandals, for you are in the sacred valley of Tuwa.” The question that bothers half the world: with or without shoes at home? In the discussion forum You can see how some places have changed their tones over the years, such as Middle Eastern countries such as Pakistan or Afghanistan and more recently, the United Kingdom. More than a new custom (although COVID made some hygiene measures stay forever), it is that this habit was probably not well monitored. Although the British case is curious. The world map of the tradition of taking off shoes at home. Seasia.co a few years ago a Reddit thread echoed an original map from Seasia.co (which also had your articlefocused on Southeast Asia) much richer because it goes one step further. It’s no longer that there are places where they take off their shoes and others that don’t, it’s just that there are places where it seems wrong for us to do so. In that small group appear Spain, France, Italy and all of central and southern America. Just the opposite of what happens in the majority of Asia and Africa: if you go to a house there and choose to leave your shoes on following your customs, you will be having a rude gesture. Here the United Kingdom finds its nuance: the norm is to leave your shoes on, but in some homes they prefer to take them off. Shoes yes or shoes no? Leaving aside religious issues and focusing on practice, the reality is that taking off your shoes is a good practice from a hygiene point of view. This study from Macquarie University in Sydney makes it clear: up to 60% of the dust and dirt that accumulates inside a house comes from outside and enters, effectively, through the feet. The pharmacist Álvaro Fernández account in El Periódico de Aragón that “99% of the shoes analyzed test positive for fecal matter” because well, we walk through places where there are traces of excrement and dirt. Microbiologist Jonathan Sexton of the University of Arizona, confirm for Very Interesting the presence in almost all soles of bacteria such as E.coli (present in 96% of cases) and Clostridium difficile. And not only microorganisms: according to The Conversation, Shoes have pesticides from gardens, lead from urban dust and carcinogenic asphalt sealers, all of that goes home. But there is no need to be shocked either: there are fecal bacteria in our mobile and that’s not why we leave it on the doorstep of the house. Simply put: the best way to have a clean house is not to clean, it is not to stain. Prevention is better than cure. Of course, everyone in their house does what they want.

In the Middle Ages it was common to sleep inside wooden closets. The big question is why we stopped doing it.

Today the idea may seem to us claustrophobicextravagant and even a little uncomfortable, but in its day, a few centuries ago, sleeping locked in a closet was the best guarantee of spending a pleasant night. Pleasant, relaxed and comfortable. Our ancestors had so many good reasons to curl up in a kind of wooden closet with sheets that the curious thing is not that they did it, but that we—since the 20th century—have abandoned the habit. In fact, there are those who propose recover the concept in the 21st century. Although, yes, with a technological point and betting on a much more modern aesthetic than the one that was popular in the times of our great-great-great-grandparents. Beds in closets? Exact. Today it may sound strange to us. To our ancestors, not so much. As I remembered recently told the BBC, there was a time, a fairly long one, between the Middle Ages and the beginning of the 20th century, when wardrobe beds were popular throughout Europe. In the 21st century, such a piece may seem curious to us, but the names with which we designate these pieces of furniture —“box bed” or “closed bed”—cannot be more descriptive. Although there were variations, with more or less elegant models and the details could vary, these items were nothing more or less than that: drawers with beds inside. Wardrobe beds were popular enough that even today we can find some important samples or references. For example, in a museum in Wick, north of Scotland, they preserve a curious bed wardrobe of pine that helps to decorate, along with other period furniture, one of the rooms where the fishermen who arrived in the region during the herring season in the 19th century stayed. Other equally curious examples can be seen in places as diverse as Austria, Holland either France. There, in the lands of Brittany, they were known as lit-clos. Even in the Rembrandt House Museumin Amsterdam, you can see today a “drawer bed” like the one used by the painter and his wife, Saskia. The writers have told us about them Emily Bronte and Thomas Adolphus and Frances Eleanor Trollope and they have even shown them to us with their brushes Pieter de Hooch either Jacob Vrel. That’s not counting the multiple references to this type of furniture, both in stories and written texts. The representations show that its details could vary, but the philosophy was always the same: overhead cabinetswith legs and often doors or a small window that could be covered with curtains. Sometimes they even had two levels different. And they always contained beds for their owners to rest. “It is the resting place of the maid or any other member of the family. The opening, which is left as the only means of access to the interior of this retreat, is provided with sliding doors, generally (as well as the entire front of the bed) beautifully carved. So that the occupant may, if he so desires, completely enclose himself,” they related circa 1840 Thomas and Frances Trollope. From peasants to aristocrats If today it is possible to find so many references it is because, clarifies the BBCthis type of structures was quite popular in homes throughout Europe, both in Great Britain and on the continent, from medieval times until the early 20th century. The British network also points out that all types of families used them. From peasants who wanted to rest after long days in the countryside to fishermen or distinguished members of the nobility. At the end of the day, its purpose could always be the same, but among furniture beds—as is the case with furniture today—there were also relevant differences. There were simple ones. And there were some with engravings worthy of a palace. But… Why did they use them? The correct question could be another: Why do we stop using them? Over time they went out of fashion and became rarities, but for centuries they guaranteed a comfortable way to spend the night. The reason? They offered privacy, were versatile, made it possible to make good use of space and to top off their service record, they helped to spend warm evenings in homes where, as remembers the historian Roger Ekircj, it was not unusual for the sap from the logs in the fireplace or even the inkwells to freeze. The teacher remembers that between the 14th and 19th centuries Europe and part of North America suffered a Little Ice Age which froze the waters of the Thames River on almost twenty occasions. With such temperatures the prospect of locking oneself in a box at night didn’t seem like such a bad idea. Especially if you take into account that it could be shared with other people. Extravagant perhaps, in the eyes of 21st century families; but the box beds were also smart. The most elaborate ones offered a seat and drawers in which clothes could be stored, just like today’s folding couches. Not to mention that they were a great option to convert places that a priori had been designed for other purposes into bedrooms. For example, the Wick Society says that in 1980, a family from the Scottish Highlandsinstalled one of these beds in the barn so that part of its members could sleep there. The room designed for family rest had become too small and the design of the wardrobe bed gave them a great solution. TIt was also not unusual for them to be offered to seasonal workers and immigrants and for them to be shared among several family members or co-workers. Perhaps this way they would be less comfortable – not to mention privacy – but on one of the nights of the Little Ice Age that hit Europe in the 17th century with icy temperatures, those wooden sarcophagi were an effective way to avoid the cold. Or that it was at least more bearable. Perhaps that is why, even today, in 2024, there are those who look at … Read more

which cars can circulate and which rest on March 28

This Saturday the Hoy No Circula Saturday scheme is launched again, the program with which the Secretariat of the Environment of Mexico City (SEDEMA) restricts the circulation of some vehicles to contain pollution in the Valley of Mexico. Once again, those who plan to use the car should carefully check the finish of their license plate and the verification hologram before going out on the street. The restrictions are not limited to the 16 municipalities of CDMX, but also extend to several metropolitan municipalities of the State of Mexico. The program also operates in: Atizapan of Zaragoza Coacalco de Berriozábal Cuautitlan Cuautitlán Izcalli Chalco Chicoloapan Chimalhuacan Ecatepec de Morelos Huixquilucan Ixtapaluca Peace Naucalpan de Juárez Nezahualcoyotl Nicolas Romero Tecámac Tlalnepantla de Baz Tultitlan Chalco Valley Also, remember that if your route passes through any of these locations, the Saturday No Circulation Day also applies. What cars and license plates does Hoy No Circula Saturday affect? The logic of the program is to reduce the number of cars in circulation to reduce emissions, but on Saturdays specific rules are applied that complement the scheme from Monday to Friday. Not all vehicle owners are forced to leave their car on the same weekend: the hologram, the finish of the license plate and whether Saturday corresponds to an odd or even week are the parameters that determine who stays parked and who can drive. It is also essential to consider that the Not on Saturday Circulation Today It does not apply 24 hours a day. The application hours go from 5:00 a.m. to 10:00 p.m., so that outside of that time frame—at night and early morning—the program does not limit vehicle traffic, as long as no environmental contingency or other extraordinary provision that adds additional restrictions is declared. In the case of March 28, 2026, the calendar indicates that it is the fourth Saturday of the month, which is why it is classified as an “even week.” Under this configuration, vehicles with hologram 1 and license plates ending in an even number are those that must remain out of circulation during program hours. If your car fits that combination, you’ll need to keep it stored until after 10 p.m. On the contrary, cars with hologram 0 and 00 retain permission to circulate without restrictions within the framework of Today No Circula Saturday. Those with hologram 2 cannot circulate under any circumstances on Saturdays. In addition to the previous assumptions, it is important to remember that there are a series of exempt vehicles that can circulate without being affected by these limitations. These are: Electric, natural gas or hybrid technology vehicles Units registered with plates for people with disabilities All those intended for urban public transport services (including funeral services) Those dedicated to school or passenger transportation Those assigned to public security and/or civil protection Those who decide to ignore the provisions of Hoy No Circula are exposed to a considerable financial penalty. The fine for violating the program ranges from 20 to 30 times the Measurement and Update Unit (UMA), which is equivalent to approximately 1,924.40 pesos at the minimum and up to 2,886.60 pesos at the maximum. Added to this economic impact is the possibility that the vehicle will be immobilized and the time that will have to be invested in resolving the situation before the authorities. Which cars and license plates are affected by Hoy No Circula Saturday? In conclusion, if you are going to travel by car this Saturday through CDMX or through the suburban municipalities of the State of Mexico included in the program, it is advisable to check before starting what hologram your vehicle has, what the ending of your license plate is and if the calendar shows an even or odd week. Hoy No Circula Saturday focuses on removing the most polluting cars from circulation, but at the same time it requires better planning of trips and evaluating mobility alternatives when the vehicle must rest.
