This is how the most brutal engineering work in urban history was born

London Underground, known in our language as the London Undergroundis one of the most famous public transportation networks in the world. With more than 543 units, 408 kilometers long and 274 stations, this precious piece of the United Kingdom capital is capable of handling up to five million passengers a day. Now, this service did not become what it is today overnight. London Underground has a fascinating history, a history that, by the way, began more than 160 years ago with a completely innovative project for the time: the construction of an underground railway. Let’s go back in time. In the 1830s, London was the largest city in the world. It was a rapidly growing global economic epicenter that needed to decongest its streetsso the idea arose that trains They will begin to move underground. The problem was that until then nothing similar had been implemented. After many years of being just a proposal on paper, a test tunnel was built in 1855 at Kibblesworth. After this step, which turned out to be a success, work began on the world’s first underground railway, a circuit between Paddington (then Bishop’s Road) and Farringdon that entered service on January 10, 1863. The locomotives ran on steam engines and the carriages were lit with gas. It was basically like putting up a traditional railway system in a closed placewhich translated into inconvenience for passengers, who often had to travel in a polluted environment with high temperatures. In any case, the metropolis continued to grow and there were more and more transportation initiatives with private investment. Therefore, in 1868 the first section of the Metropolitan District Railway was inaugurated. This was a service that ran between South Kensington and Westminster (now part of the District and Circle lines). Electricity reaches trains Both services continued to expand as tunnel construction techniques improved. On December 18, 1890, The City and South London Railway launched the first electric railway. This was a very important advance because it allowed us to solve some of the main drawbacks of the service. In 1905, electrification came to the District and Circle lines, but the London Underground network operated as separate systems. This changed after 1906, when companies began to make their way deep into the city to unify. In all this, the name ‘Underground’ did not yet exist. Artist’s representation of a platform on Baker Street London in 1906 The companies that had come together for the project proposed different names, including ‘Tube,’ ‘Electric,’ and ‘Underground,’ but the latter was the winner. In this way, in 1908 it appeared for the first time the name ‘Underground’ in the seasons, and he did it with the roundel symbol that we know today. The technological progress of the London Underground seemed unstoppable. That same year, electronic ticket-issuing machines arrived and in 1911 the first escalators were installed. In 1929, manually operated doors began to become extinct. These were updated with pneumatic systems. Until this point, the service was operated by the Underground Electric Railways Company of London (UERL). In 1933, however, underground transportation services merged with the railroads and bus services under the London Transport brand, which was overseen by the London Passenger Transport Board. That same year Harry Beck’s map appearedan element intended to guide users. The system had grown so large that some stations were just meters away, while others were kilometers away. It is a cartography that was received with skepticism, but ended up triumphing. Aldwych tube station, in 1940 For the first time, decisions about London’s public transport services were perfectly coordinated. This allowed us to improve the service and outline an ambitious improvement plan. However, the outbreak of World War II in 1939 meant that the plan could not be completed as originally envisioned. The underground transport service was converted into a huge air raid shelter between September 1940 and May 1945. Some stations were also used during the war as a warehouse to keep valuable historical items safe, for example pieces from the British Museum. After the war, in 1948, the London Passenger Transport Board acquired a public role. HE nationalized and became the London Transport Executive, years later being renamed the London Transport Board and operating under the orbit of the Ministry of Transport. The system also suffered several tragedies. In 1975 a train heading south did not stop at the final terminal and crashed at the end of the shift. 43 people died and 74 were injured. In 1987, a fire claimed 31 lives at King’s Cross station. Later, in 2005, an attack on the London transport system It caused 52 people to lose their lives. Nails contactless cards called Oyster They were implemented on the London Underground in 2003, but by 2014 you could already pay directly with contactless bank cards. By 2016, some lines provided evening service on weekends. Currently the service is run by an organization called Transport for London (TfL) which comprehensively manages the city’s state transportation strategy.

an intact Celtic city 2,000 years old

It seemed like the perfect location to build a highway. One of those in which the citizens of the Czech Republic want drive at 150 km/h. But when the bulldozers arrived, the workers realized something: someone was already there. Specifically, some citizens who had built their houses and businesses there 2,000 years before. What has happened? He East Bohemian Museum next to the University of Hradec Kralovehave found a 2,000-year-old city where a highway was planned. This has been confirmed by the museum itself, which in a statement also explains that the settlement was especially rich, taking into account the enormous amount of jewels and coins found. The road is the D35 highwaywhich is under construction in the east of the country. When completed, the road will add two milestones to the history of Czech infrastructure. The highway will be the second longest in the country and will contain the longest tunnel in the Czech Republic. The intention is to provide relief to the current D1 highway, which is currently saturated with cars and trucks. They were already there. 2,000 years ago, specifically. In the preliminary phase of excavating the land through which the road was to pass, archaeologists have found a “unique site in Bohemia”, according to the museum itself. This is a key city in the area. It is believed that its commercial and economic impact reached other nearby regions since it was located in the famous Amber Route. According to their calculations, the city would extend 25 hectares and they believe that its maximum splendor was reached in the 2nd century BC. Data that they have been able to extract from the enormous amount of metal objects such as coins, ceramics and remains of homes that have been found in the excavation. What was the city like? According to experts, such as those consulted by Live Sciencethe city developed in the La Tène era, that is, the final phase of the Iron Age. It must have been one of the most important cities in the area since productive structures and evidence that luxury ceramics were manufactured there have also been found at the site. Experts say that the city had to be a place of passage on long-distance journeys, which is why it was very important for all the settlements in the Middle Danube region and southern Germany. Two structures have also been found that could be one or two sanctuaries. Intact. One of the good news, they assure from the museumis that archaeologists have highlighted the good condition of the findings found. In fact, they point out that these have not been victims of illegal irrigation or those who search for treasures with metal detectors. This has made it possible to find a first layer with an unusually high density of objects. This has allowed the recovery of 22,000 bags with all types of finds, which places it as one of the most important excavations in the area. And now? Now in the Czech Republic they will have to look for an alternative to the road. The city found is located within the Litomyšl–Janov section, a particularly delicate section due to the number of urban agglomerations in the area. In fact, state entities point out that it has been difficult to reach an agreement with nearby cities. Finally, the section will have numerous bridges and a ring road has been designed next to the city of Litomyšl with the aim of reducing the traffic that currently circulates through this city. If there are no new surprises, the highway should be completed in 2029.

Vivo has just presented the Vivo X300 Ultrathe most powerful model in its catalog to date. It is a very important device for the company, which although it is used to competing in the most premium segment, is the first time it has launched the Ultra model outside of China. Because yes, the Vivo X300 Ultra will arrive in Europe and, of course, in Spain. The device arrives armed to the teeth in each and every one of its sections. Vivo has not left anything out and offers a high-capacity battery, the latest from Qualcomm under the hood and a triple camera with a dual 200 megapixel sensor, teleconverter and grip that promises a lot. Without further ado, let’s get to know it better.

In the module area, the device is 8.58 mm thick, something that, it must be said, is normal in recent high-end terminals. The weight varies depending on the color, but in no case, regardless of whether it is black or green, does it drop below 230 grams. However, this thickness and weight is offset by a high-capacity battery and an all-terrain camera. The rear has a huge camera module integrated into the chassis that draws attention, but otherwise it is quite simple. The most striking thing is, of course, the compatibility with the side grip, the tripod ring and the teleconverter. The latter will help us increase the telephoto distance and take photos from even further away. Basically, we can turn the mobile phone into a “compact” camera based on accessories. Vivo X300 Ultra | Image: Live In the front we find a huge 6.82-inch AMOLED panel with QHD+ resolution (3,168 x 1,440 pixels) which leaves us with a density of 510 pixels per inch. This screen moves at 144 Hz and occupies, according to the firm, 94.5% of the front. The brightness is also on par with the high-end, reaching 4,500 nits of peak brightness and 1,800 nits of maximum brightness. …and huge inside Vivo X300 Ultra | Image: Live Under the hood, the Vivo X300 Ultra features the latest in components.

It won’t be by brute force, of course. The operating system is Android 16 and runs under OriginOS 16, Vivo’s customization layer. It has Google Gemini, the entire Vivo creative AI suite and everything you would expect in terms of connectivity: Wi-Fi 7Bluetooth 6.0, dual SIM, eSIM and NFC. The battery amounts to 6,600 mAh with 100W fast charging and 40W wireless charging. As a curious fact, the device is sold in a pack that includes accessories for the camera and charger. Let’s talk about the camera Vivo X300 Ultra | Image: Live Vivo has been betting heavily on photography in recent years. On this occasion, the firm repeats its collaboration with ZEISS and opts for a triple lens system composed of a 200 megapixel wide anglea 50 megapixel wide angle and a telephoto that shares resolution (and optical stabilization) with the main sensor. This is capable of reaching 100x magnification using digital zoom, although the optical zoom is lower. Vivo X300 Ultra | Image: Live What is the key? Stabilization and video. On the one hand, the main sensor is capable of recording up to 8K, but the set supports up to 4K at 120 FPS and 10-bit Log format. Vivo also boasts of having achieved the CIPA 6.6 stabilization rating in its wide angle, CIPA 6 in the wide angle and CIPA 7 at telephoto. In the company’s words, it is the highest degree of professional stabilization currently available in a smartphone. Vivo X300 Ultra | Image: Live To complete the set, the Vivo X300 Ultra has a 400 millimeter Vivo Zeiss Gen 2 Ultra teleconverter (equivalent to 17x optical magnification), a grip kit and a tripod adapter.

There is only one Bugatti La Voiture Noire and no one knew who owned it. The answer was in the Porsche garage

For years, the owner of the most exclusive car in the world It was quite a mystery. Only one example of the Bugatti La Voiture Noire exists and, since its presentation at the 2019 Geneva Motor Show, no one has officially confirmed who had purchased it. That made the Internet full of theories and speculation: from elite footballers to oil sheiks. So much so that the then CEO of Bugatti, Stephan Winkelmann, publicly denied that the buyer of this gem of collecting out Cristiano Ronaldoone of the most repeated names for having several Bugatti in his garage and enough financial liquidity to afford their purchase. The mystery had remained intact until now. A work of art inspired by a missing car. He The Black Vehicle was born as an obsessive tribute to one of the most legendary automobiles in history. Bugatti designed this unique example looking at the Type 57 SC Atlanticcreated in the 1930s by Jean Bugatti, son of founder Ettore Bugatti. Only four units of that Atlantic were manufactured, and one of them, precisely the one known as La Voiture Noire, disappeared without a trace before the Second World War, and has never been found. The 2019 model takes up that heritage with an overwhelming technical proposal in the purest Bugatti style: 8-liter W16 engine with 1,500 HP, four turbochargers and six exhaust pipes that emerge on each side of the body as a direct nod to the design of the original Atlantic. With its black lacquer finish, sculptural lines and the weight of a legend on the body, Bugatti sold this unique specimen to an unknown owner for around 16.7 million euros. The mystery solved: Ferdinand Piëch, grandson of Porsche. It is now known that the Bugatti La Voiture Noire never really left his home since it was Ferdinand Piëch who acquired it. Piëch was the grandson of Ferdinand Porsche, founder of the brand that bears his surname, and one of the most influential engineers and managers of the 20th century in the automotive world. During his time at the head of the Volkswagen Group, he was the main architect of the Bugatti revival as an extreme luxury hypercar brand, driving the development of the impressive W16 engine that beats under the hood of La Voiture Noire. The history of that engine has its own epic. The concept of the W16 block was hand sketched by Piëch On paper he was traveling at 320 km/h on a Japanese bullet train. As if it were a premonition, that same engine turned the Bugatti Veyron into the first production car to become a missile. capable of exceeding 400 km/h. Ferdinand Piech passed away in 2019the same year that La Voiture Noire was presented to the world. The car, however, was not delivered until 2021, then passing into the hands of his son Anton Piëch as heir. The twist: the heir needs liquidity. Anton Piëch thus inherited the most expensive hypercar in the world at the time of its delivery. Now, however, he has made a decision that closes a symbolic circle: wants to sell it. According to sales documentation to which has had access to the German economic newspaper Handelsblattthe La Voiture Noire is offered through a discreet bidding process for 23 million Swiss francs, approximately 25 million euros. The reason for the sale of such a motorsports legend is the need to finance Piech Automotivetheir own electric vehicle startup founded in 2017. The company has been trudging along for over a decade and still doesn’t have a production vehicle. According to sources cited by Handelsblattthe company is also exploring a possible integration under the umbrella of the Chinese group Chery, although neither party has confirmed the details.

thousands of soldiers converted into Tomahawks that the US no longer has

In recent times, the United States has fought many of its wars without the need to deploy large contingents on the front lines, relying on weapons capable of traveling more than 1,500 kilometers with millimeter precision and being launched from thousands of kilometers away. But there is a detail which can be crucial: replenishing that type of weaponry can take years, not weeks. The Tomahawk countdown. The United States has based the start of the conflict on a key advantage: hit at distance without exposing itself, relying massively on cruise missiles Tomahawk. However, that advantage is evaporating at high speed, with more than 850 missiles launched in just one month, a figure that represents a significant part of the total available arsenal and that has led some commanders to openly speak of “alarmingly low” levels. The problem is not only how much has been spent, but how slowly can be replaced: They are manufactured in limited quantities, they take years to produce and their intensive use in multiple recent conflicts has left a stock much more fragile than the official discourse makes it seem. From remote war to direct risk. Because the Tomahawk is not just another weapon, it is the pillar that allows Washington attack without risk pilots or troops in highly defended environments. From that perspective, its wear and tear completely changes the nature of the conflict, because it forces remote attacks to be replaced. for closer operationswhere planes and soldiers are much more exposed. In fact, the very development of the campaign already points to this turn: after the first long-distance blows, the United States has had to resort to more conventional ammunition and to deeper incursions, accepting a level of risk that at the beginning of the war he had managed to avoid almost completely. The Arleigh Burke-class destroyer USS Bainbridge fires Tomahawk missiles from the deck while underway in the eastern Mediterranean, in support of Operation Epic Fury, March 3, 2026 A scarcity that conditions. It we have counted before. The accelerated consumption of these missiles not only affects the war in Iran, but also opens a much bigger problem: Leaves the Pentagon with less room for other critical scenarios, especially in the Indo-Pacific facing China. Let’s think that Tomahawks are a of the key pieces for any high-intensity conflict against a similar power, and its reduction poses a obvious strategic dilemma: continue spending them in the Middle East or save them for a possible much more demanding confrontation. In fact, the urgency has reached the point of proposing missile transfers from other regions and put pressure on the industry to multiply production, something that, in any case, it will take years to take effect. The arrival of troops. In parallel to this silent attrition, the United States is moving thousands of soldiers to the region, in a buildup that could exceed 17,000 troops ready to operate near Iran. Although officially it is presented as a measure of pressure or preparation for contingencies, the context reveals another reading– As the ability to hit from afar decreases, the need to have options on the ground. Marines, parachutistsspecial forces and logistical support units are being positioned for missions ranging from securing sea routes to capturing strategic objectives or nuclear facilities. Possible missions, real risks. Because the operations that are being considered are not minor or fast, but complex interventions in highly hostile environments: take key islandssecure points in the Strait of Hormuz or even penetrate Iranian territory to neutralize critical assets such as uranium. Each of these scenarios involves facing missiles, drones, naval mines and prepared local forces, with the added risk of operating in tight areas and under constant fire. Unlike missile attacks, there is no safety distance: once on the ground, troops become concentrated and vulnerable targetsrelying on aerial and defensive coverage that is also under pressure. The turn towards a more dangerous war. Inevitably, the result is a profound change in the logic of conflict: what began as a campaign dominated by technology and reach is transforming into a situation where the human factor returns to the center. If you will also, a key idea aims to clearly prevail, one where the war in Iran is approaching a unprecedented scenario for the United States, and where thousands of its soldiers may have to assume the role they previously Tomahawks played. Not by strategic choice, but by necessity, in a context where the shortage of high-precision ammunition coincides with an accumulation growing number of troops ready to intervene in one of the most dangerous environments in the world.

what it is, what it is for, prices and how you can get one to use in your projects

Let’s explain to you What is it and how to get an API qwen. This is essential code to be able to link your production models. artificial intelligence when developing an app or creating a workflow that includes them. And although we have already told you how to get Claude’s, ChatGPT’seither that of DeepSeekwe are also going to tell you about the AI ​​belonging to Alibaba. We are going to start this article by explaining what it is and What is an API key for? from Qwen, trying to make sure anyone can understand the concept. And then, we’ll tell you step by step how you can get yours, as well as their prices. What is the Qwen API and what is it for? Qwen is one of the most powerful artificial intelligence models on the market. It comes from China, and behind it we find the online giant Alibaba, which offers several models with different features and functions. Qwen is on the one hand the name of the chat, whose address is qwen.ai. But it is also the name of the AI ​​model underneath that makes it work. Think of the AI ​​chat as a complete car, and while what drives it is the engine, it is the model. And then, from time to time new versions of these models come out. Each of these AI models occupies many terras, and therefore, if you want to link it to an external application or project you will not be able to install it on your server. Instead, what you will do is connect your project to one of these models, build a bridge between your application and Qwen, and the key that opens the doors of that bridge is the API. An API is a unique key that is used to connect an app and an external service. In this case, the API serves to connect other applications with Qwen, or rather, the artificial intelligence model that powers it. This key, in fact, works for several models, although depending on which one you use, you will consume more or less tokens. The idea would be that when you write something to the bot that you have connected with an API, this bot sends the message to the AI, and that when the AI ​​generates the response it reaches the bot and it can show it to me. And since the bot and the AI ​​are on different servers, possibly in different countries, I’m going to need a bridge. And this bridge is the API. The Qwen API is paid. You pay for each token consumedwithout a fixed monthly fee. First you will have to buy credit packsand then these will be spent as you use the API. When you make a request, depending on the processing it requires and the task involved, you will spend these tokens or tokens, and when you run out you will have to buy more. But in exchange, what you have is the possibility of use Qwen in your projects to create your own chatbot or assistant, to automate tasks, to analyze texts, videos or audio and make transcriptions and summary, generate code, and ultimately for whatever you need. You will have the AI ​​within the application, but not natively, but you will have connected both. Token types and API prices The price of Qwen APIs depends on several things. For a start, It depends on the model you want to use.. If you are going to use the most powerful model it will be more expensive, since it is a model that consumes more resources. Meanwhile, the lighter models will have lower prices. There are two types of tokenthe input ones (Input) and the output ones (Output). Input tokens are the consumption of the text that you send to the model with a prompt. And the output is the response it generates. The price of the tokens is per million of them. As for the price, it depends on whether you use a full or lighter model. This is a table with prices of current flagship models. Remember that prices correspond to each million tokens. Model Input (for 1M tokens) Output (per 1M tokens) Qwen3.5-Plus 0.4 dollars 2.4 dollars Qwen3.5-Max 1.2 dollars 6 dollars Qwen3-Coder-Next 0.3 dollars 1.5 dollars Qwen-Plus 0.4 dollars 1.2 dollars Qwen3.5-Flash 0.1 dollars 0.4 dollars How to get your Qwen API To generate a Qwen API, the first thing is create an account on Alibaba Cloud. For that, go to alibabacloud.com and choose the option to register. In the process they will ask you for a payment method so that invoices are charged there when you use the API and spend tokens. Once you have an account, you have to go to the APIs section of Alibaba Cloud Model Studioentering directly in this link. Once inside, press the button Create API Key that will appear at the top right. This will open the window to generate the API, where you will have to choose the workspace where you want to have it and give it a description to differentiate it from the others. The ideal is to use an API for each project where you want to link Qwen. And that’s it. Only with this you will have created your API, and you will be able to see it in the list that appears on the Alibaba Cloud Model Studio APIs website. You can now use this code to link Alibaba AI wherever you want.

China is giving an overwhelming lesson in nuclear power plant construction to the rest of the planet

The time it requires the construction of a nuclear power plant From the moment the concrete is poured until the moment it is connected to the electrical grid, it takes between 15 and 19 years in the West; between 7 and 9 years in Asia and the Middle East; and 6 to 10 years in India and Russia. And the total cost of the project usually ranges between 24,000 and 60,000 million dollars. Barakah 4 nuclear power plantin the United Arab Emirates, has four nuclear reactors, took 9 years to build and cost $24.4 billion. On the other hand, the nuclear plant Hinkley Point Cin the United Kingdom, clearly illustrates the execution problems faced by some Western nuclear projects. After several delays Its first reactor will come into operation at best 13 years after the start of construction of the plant. And its final cost will exceed 50 billion dollars. At an intermediate point, Vogtle Unit 4 is established, in the US, which has taken 11 years to be operational and has cost about 35 billion dollars. As can be expected, the number of reactors and the technology they use have a profound impact on the cost of the plant and the time that needs to be invested in its development. Even so, as we have just seen, construction costs and time vary greatly from one region of the planet to another, especially if we introduce China into the equation. And in this scenario the country led by Xi Jinping is unbeatable with a average construction time of 6 years per nuclear plant and a cost of $2,500/kW compared to the 10-year average and almost 8,500 dollars/kW for the rest of the planet. China’s recipe is the most competitive Shangwei Liu explains clearly in the article you published on the website of the Roosevelt Institute what is the strategy that China has devised to reduce the cost and time invested in the construction of its next-generation nuclear power plants. Its plan is based on two pillars: the reconstruction of the supply chain and economies of scale. To a large extent, China’s success is due to the fact that it has managed to create a national supply chain that is immune to the ups and downs and instability of the international market. In addition, it has a lot of qualified labor in all links of its supply chain. There is only one country on the entire planet capable of approaching China’s numbers in this complex and demanding scenario: South Korea. On the other hand, the economy of scale that has given China so much joy in a very wide range of markets also has a place in the production of the components required by nuclear plants. Furthermore, when replacing components manufactured abroad by local elements This Asian country managed to drastically reduce costs during the first decade of this century, and stabilize them during the last decade. However, there is another factor that works in China’s favor and that we cannot ignore: its coordinated industrial policy and stable regulatory framework allow it to carry out long-term planning. There is only one country on the entire planet capable of approaching China’s numbers in this complex and demanding scenario: South Korea. Its latest nuclear plant projects show a cost of between 3,500 and 4,500 dollars/kWwhich places it close to China, with 2,500 dollars/kW, and well below the average of 8,500 dollars/kW for the rest of the planet. This achievement is the result of approaching nuclear energy as an industrial assembly line and not as a set of isolated engineering projects. Again, economy of scale makes the difference. The US numbers are much less favorable. And the total cost of its latest nuclear plants exceeds $15,000/kWalthough presumably this figure will moderate until it barely exceeds the $10,000/kW in future projects. If Western countries want to drastically reduce their costs and moderate the time it takes to construct their nuclear power plants, they will necessarily have to look towards China and South Korea. The reconstruction of their supply chain is essential, and, in addition, they will have to resolve the crossroads posed by the commitment to large reactors, or by compact modular reactors. At the moment there are no other options on the table.

The war in Iran is turning tourism upside down. And that translates into something for Mallorca: thousands more Germans

In just over a month, the Middle East conflict has reminded the world that, at least in the 21st century, the seismic wave of wars is felt far beyond where the bombs fall. Its effect has already spread to the price of oilthe stock market and geopolitics and now threatens to shake the shopping basket. Another sector in which it is also leaving its mark (and a lot) is the touristwho has seen how in a matter of weeks flights were canceledthey reinforced routes and basically demand swung at a global level. And that is being felt strongly in the Balearic Islands. More flights to Mallorca. That the Balearic Islands see their flight schedule reinforced at the gates of Easter and with summer just around the corner is nothing new. What is curious is that the programming is shielded with dozens and dozens of extra frequencies, such as reveals Mallorca Diarywhich estimates that the war in Iran has led to more than a hundred extra flights being planned between Germany and Mallorca for the start of the season. In practice this translates into something that will soon be noticed in the Balearic Islands: tens and tens of thousands of extra places for German travelers until June. How many flights are there? Yes. The biggest injection will come from Eurowing, an airline low cost based in Düsseldorf and part of the Lufthansa Group. A few days ago its managers announced the scheduling of a hundred extra flights to Palma, an effort that they relate (without mentioning it directly and explicitly) to the instability that the Middle East is experiencing. “The airline responds to the changing demand of the sector and reinforces its offer to the western Mediterranean,” clarify. According to the calculations of the company, the reinforcement of its operations with Mallorca will result in 36,000 extra seats until the end of May. “Around 100 additional flights are planned to Palma, along with around 70 connections to the Canary Islands (Fuerteventura, Las Palmas, Tenerife), as well as to Faro, Málaga, Naples and Nice,” Eurowings specifies before specifying that the new scheduled flights will operate from the airports of Berlin, Cologne, Düsseldorf, Hamburg and Stuttgart. Beyond Eurowings. The Lufthansa airline is not the only one that has decided to redouble its commitment to the Balearic Islands. Condor Flugdienst, another German operator, will reactivate two connections with the Spanish archipelago starting in May: one will be the Dortmund-Palma route, which will be covered daily with an Airbus A321; the other will link the Münster/Osnabrück airport with Mallorca. The list of companies that will target the Balearic Islands offer in the coming weeks are Ryanair and TUI Fly. The first offers a route to Mallorca from Friedrichshaffen, in Baden-Württemberg (Germany). Regarding the second, Tourinews inform that a few days ago it announced the scheduling of 68 additional flights with around 10,000 seats from several German airfields, including Hannover and Munich. The destinations are spread across various points throughout southern Europe, including Greece, the Canary Islands and Mallorca. “They have changed their plans”. It is not just that German airlines seem to look with redoubled interest at the great destinations of southern Europe and the Mediterranean. The sector itself recognizes a change in trend that is related to the war in Iran and the influence it is exerting on the market. “Many tourists who had not yet booked and were planning to travel to destinations in the Middle East have changed their plans at the last minute and opted for other places,” clarify to Mallorca Diary from the Business Group of Travel Agencies of the Balearic Islands (AVIVA). a few days ago The reason assuredciting data from tour operators, that British reservations have skyrocketed by 40% in the Balearic Islands. The Canary Islands have also recorded an increase of 16%. “Last minute increases”. Last week the Hotel Business Federation of Mallorca (FEHM) calculated that the average occupancy during Easter will be around 70%, a level similar to that of past years, with 92% of its places activated. In the specific case of Palma, the forecasts were somewhat better and almost 90% of the available rooms were expected to be filled. These are, however, the starting data. In general, the group is cautious, remembering the “uncertainty” that reigns in the market internationally and also recognizing that its initial estimates may be out of date, opening the door to an increase in reserves. “There may be increases due to last minute sales,” anticipates the executive vice president of FEHM. Has the scenario changed that much? The truth is that yes. And in several aspects. The war and its consequences, which extend far beyond Iranian borders to the rest of the Persian Gulf, have made tourists from other countries be suspicious of destinations established until now. A few weeks ago, the Mabrian firm studied the security perception indices of nations such as Qatar, the Emirates and Saudi Arabia and found that the indicator had plummeted. The most curious thing is that it has also taken its toll on other distant tourist spots, such as Jordan, Türkiye or Egypt. The study was carried out shortly after the US and Israeli attack on Iran and Tehran’s subsequent reaction, which turned the airspace of much of the Gulf upside down. Since that region plays a key role as an air interconnection point on routes between Europe and Asia, the war also took its toll to connections with countries like Sri Lanka. Surprising (but not that surprising). In reality, the latest movements of Eurowings, TUI Ryanair only confirm what analysts tell us. weeks anticipating: that part of the demand that now views the Middle East with suspicion will be redirected towards other beach destinations in Western Europe. Which is it? In mid-March the BBC spoke from Portugal, Italy and Spain, as well as the Caribbean, Mauritius and the USA. They were not simple predictions. The British chain cites data from a famous travel agency, Thomas Cook, which already at that time … Read more

from sharing mobile data to paying again like a decade ago

Saturday is a good day to have your internet cut off. At first you don’t notice, because you’re at home and you don’t use the computer (as much). But you end up finding out, and that’s what happened to me when I realized that I was without my O2 fiber connection, againfor the underground works from the A-5, again. Two days later I’m still the same, like many residents of the area, and this is becoming a small (but bearable) headache. The cuts are back. These works have already caused cuts in the past. They did it in July, August and November of 2025, and also in January 2026. Each time the affected areas and operators have occurred, they have varied, but for example on social networks there is data that indicate that this time the cut has been important and has affected to Movistar/O2 clients,Orange, VodafoneJazztel or Digi. Meanwhile, unlimited data. Spotting the problem on Saturday morning, I called my operator, O2, to find out what was happening. They confirmed to me that it was a fiber optic cable cut due to the works on the A-5, and they explained to me that they hoped to resolve the problem as soon as possible. And as in the previous outage, they told me that during this period I was offered unlimited mobile data on all the lines associated with my contract. It is something that operators usually offer in these cases and that certainly makes the problem mitigate… although it does not disappear. He tethering saves (quite a lot) the papers. Since then I have been using my computer with mobile data: I have shared the connection on my smartphone through tetheringwhich allows me to work normally and at decent speeds without problems. This weekend I have also used this connection, sharing it with the Chromecast on my TV to watch a series or movie without problems. Paying as before. Businesses in the area have also been affected by these service cuts, and the example is a supermarket near my house where this weekend there was no option to pay with a mobile phone. The POS did not accept contactless payments and you had to pay either in cash or with a physical debit/credit card, inserting it into the POS slot. Better to be proactive. Users have few options here beyond calling the operator to find out what happened and to have them activate that unlimited data if they had not already done so. Here it is advisable to be proactive and call because at least in my case until I called they did not activate those unlimited “bonuses”, and it makes sense: the operators may not know which users exactly are affected. If we want to have this option we will have to call and probably wait a few minutes until an agent answers us, something that may take time because these breakdowns affect many people. In my personal case the wait was about 5 or 6 minutes this time. It’s time to wait. As is often the case on these occasions, there is no clear estimate of when the problem can be resolved. In January the disconnection lasted approximately two days, and this time the outage is already on its way to lasting up to three days or more. Neither the operators nor the Community of Madrid offer much information in this regard, and in most cases the only thing that users can do is be patient. In Xataka | There is an extensive system to avoid being cut off in the 48 km underground of the M-30. It’s time to renew it

science gives victory to walking with inclination

When we have the idea to start lose weighta very clear scene appears in our minds: run and sweat profusely to burn all the fat faster. However, the ‘secret’ may not be in the speed at which we are walking or running, but rather in the inclination on which a training protocol has even been generated to try to achieve the best results. Although the question is: is there evidence to support it? It has been seen a lot. With a look at social networks, surely at some point you have come across the classic video where it points out that we are doing things very wrong to lose fat. And it is not true that if you only run or walk horizontally it is as if you were not doing anything, but it is true that adopting an incline system, whether on the gym treadmill or with the natural slopes around us, is an interesting strategy. Although it does not stop here, since the protocol 12-3-30which is basically walking at a 12% incline, at 3 miles per hour (which is about 5 km/h) for 30 minutes. The metabolic dilemma. To understand why walking uphill can be better than jogging on the flat, you must first differentiate between total caloric expenditure and percentage of substrate used, that is, where the body gets that energy from. Here, a recent study published in 2025 directly compared the 12-3-30 training with regular, free jogging, and the results showed that, although the same energy was expended, walking with an incline oxidized a greater percentage of fat. In concrete figures, the study details that, consuming the same number of calories, the 12-3-30 protocol extracts 40-41% of its calories from the fat that we want to burn, compared to 33-34% which is achieved by running. Although the trap we have is time, since the 12-3-30 system is less efficient because it takes more minutes to burn the same calories than running at high intensity. Speed ​​is not key. Given the reason why this happens, we have to put ourselves at the point of maximum lipid burning, which is called Fat Max and that is achieved at an average intensity of effort. Something that can clash head on with the idea that the harder we try and the more we reach our maximum limit, the more fat we burn. But the reality is that when you run at the maximum possible intensity, the body needs a quick energy source to be able to meet the demands to which we subject it. That is why you start consuming carbohydrates and not fat, meaning that, although running as hard as possible you burn more calories per minute, the proportion of fat that is ‘destroyed’ is much lower. This way, incline walking keeps us right in that aerobic “sweet zone” where the body has enough time to use fat as its primary fuel. What happens. But it’s not just speed, speed plays a pretty important mechanical role. Here a study focused on the metabolism of women showed that walking with only a 6% inclination It significantly increases energy expenditure and fat oxidation compared to the same flat exercise, even when the perception of effort is the same. The reason is in the muscle fibers. The most important thing to keep in mind is that, by tilting the treadmill, we force the body to make an extra effort against gravity, which alters biomechanics. Muscle activation studies cited by specialized journals show that inclination triggers the recruitment of the quadriceps, the gastrocnemius (the gastrocnemius) and the soleus. That is why this greater demand from the large muscle groups comes from our fat reserves. More benefits. In addition to everything we have said, we must also highlight the sustainability factor. It must be kept in mind that running has a high barrier to entry, since it generates great stress on joints such as the knee, ankles and hips due to the flight phase and the continuous impact against the ground. At the other extreme, we have to walk with an incline, which is a low-impact exercise, since it allows us to raise the heart rate to levels of demanding cardiovascular work without subjecting the joints to that aggressive wear. This translates into having better adherence to exercise, since it is easier to maintain a routine of walking with an incline four days a week for months, than to maintain a routine of running without falling into abandonment due to the inconvenience it generates.
