Risk

They have found a bacteria capable of increasing your risk

by

We often think of the health of our mouth as something completely isolated that has no more significance than the odious cavities that we get. forced to go to the dentist or the bad breath. However, science has been warning for years that the mouth is the gateway to much more complex systems, such as the possibility that a bacteria from our gums travel to the breast tissue and may accelerate tumor growth. An unwanted traveler. The protagonist of this new discovery is the bacteria Fusobacterium nucleatum, an old acquaintance of dentists. We are talking about an opportunistic bacteria that thrives in dental plaque and is one of the main culprits of periodontitis, which is undoubtedly one of the most recognized gum diseases. What the team led by Dipalo Sharma has recently demonstrated is that this bacteria does not stay still on the gumsbut it has the ability to travel through the body to the breast tissue or even also is already linked to colon cancer. Its effect. The study In this case, he used mice to simulate two different scenarios in order to see how this very common bacteria behaved. The first of them was to inject the bacteria into the breasts of healthy mice, where precancerous inflammatory lesions began to be seen. In the case of injecting into existing tumors is where the alarms go off, since in these mice the presence of the bacteria tripled the size of the cancer and caused lung metastases in 100% of the cases observed. How he does it. It’s the million-dollar question: how does a bacteria from the mouth know that it has to go to the chest and how does it manage to do so much damage? Science has found an explanation at a molecular level that begins with inflammation of the gums in periodontal disease, since this causes the bacteria to enter the bloodstream. Once in the stream, the bacteria begins to travel and takes advantage of a very specific protein, called Fap2, which acts like a key that searches for a specific lock: a sugar called Gal-GalNAc, which turns out to be very abundant on the surface of breast cancer cells. Creating a shield. Once the bacteria adheres to the tissue thanks to this specificity, it begins to colonize, but it also has the ability to suppress the cells in charge of our defense. And specifically those that defend us from cancer cells that bypass the body’s checkpoints. Furthermore, it induces direct DNA damage and preferentially colonizes cells that have mutations in the BRCA1 gene, exacerbating the risk in genetically predisposed people. Dental hygiene. The result of this research leads us to a very clear question: does not brushing your teeth cause cancer? Logically not. In the field of health, causality is not as simple as ‘do this and that happens’, but rather it works as an accumulation of risks that increase the chances of generating a problem such as cancer. A risk factor. In this case, science suggests that having periodontitis, due to poor hygiene sustained over time, is associated with an increase of around 22% in the risk of suffering from breast cancer. And it is not the first time that dental disease is a risk factor of this type. A well documented case is in the relationship between deep dental caries and bacterial endocarditisan infection of the inner lining of the heart. That is why the recommendation here is always to maintain good oral hygiene and always treat cavities as soon as possible when they appear. Images | Caroline L.M.

Let’s tell you how to look at areas at risk of flooding with the new experimental map created by Google. With this tool, you can navigate and zoom into any area of ​​the world to see where there are dangers of extreme flash floods, with special interest in those river and sudden floods. For example, at the time of writing this article we find that a good part of Spain cannot absorb even one more dropwhich makes the storm feast expected in February be especially dangerous. You can see this on the Google map, especially in the west of the country. Google Flood Risk Map To enter this map you have to go to the website sites.research.google/floods. This will open a world map, with a column on the right where you can turn visualizations on or off. By default they will be shown above all areas most in danger of flash flooding what’s in the world. On this map you will be able to zoom in or activate a hybrid map to see satellite photos of the areas. You can get closer to the area you want, where you will see colored dots information that indicates the danger of flooding in each area. Here, if you click on any of the points On the left you will see a window with expanded information, especially seeing how the dangers evolve and from what source the information is obtained.

The biggest geopolitical risk on the planet is not Greenland. It’s a smaller island with a disturbing neighbor: Taiwan

by

Throughout the cold warthere were points on the map whose real value was not measured by their size, but by what could be triggered if someone tried to force the situation. Today, one of those places once again concentrates gazes, calculations and uncomfortable silences among the great powers. and it is not in Greenlandbut on a smaller island. The global risk enclave. The tension between United States and China is concentrating increasingly evident in Taiwan, a territory small in size but enormous in strategic consequences. While Washington allows itself dramatize scenarios secondary in the Arctic, Chinese military maneuvers around the island they have been become routineincreasingly aggressive and similar to real blocking or maximum pressure tests. The absence of clear and quick responses from the White House projects a dangerous sign in a context where deterrence depends less on formal declarations than on immediate political reflections. The deterrence that is called into question. The contrast between Trump’s political lukewarmness and the warnings of the US military apparatus itself has opened a visible crack. The Telegraph said that Pentagon commanders have been warning for some time that China is preparing to be able to fight and win a conflict over Taiwan before the end of the decade, although that diagnosis does not always translate into credible public messages. This dissonance reduces the perceived cost of a Chinese action and leaves open the possibility of a calculation error on Xi Jinping’s part, especially if he interprets American caution as a lack of will. Taiwan as a key piece. Taiwan’s importance to the United States is not symbolic, but rather structural. We are talking about an advanced democracy in a region dominated by authoritarian regimes, one that houses the core of world production advanced semiconductor and is part of the first island chain that limits military projection China in the Pacific. From that perspective, the fall would be a direct blow to the global economy, Western technological superiority and Washington’s strategic credibility in Asia. Taiwan Navy It’s not 1996 anymore. Unlike previous crises, when American naval and air superiority was overwhelming, today the balance is much tighter. China has built a navy larger than the American in number of ships, an air force with hundreds of fifth generation fighters and, above all, a massive arsenal conventional missiles capable of hitting bases, ports and fleets at great distances. Although the United States continues to spend more on defense, lower Chinese industrial costs and its geographic proximity to the theater of operations significantly erode that advantage. The “logistics” weapon. The New York Times recalled in a column that one of the factors that moderated Beijing’s behavior for years was its dependence on critical raw materials from countries aligned with the West, especially Australian iron ore. That brake is weakening as China secure supplies alternatives from Africa, reducing their vulnerability to sanctions or blockades in the event of conflict. The result: an environment in which the economic costs of a war over Taiwan, while enormous, are already They are not so deterrent for Beijing as they were in the past. No clear winner. The open simulations and internal leaks From Washington they agree on a most uncomfortable diagnosis: if necessary, a war over Taiwan it would be devastating even for those who managed to impose their immediate objective. China could fail in invasion, but the United States and its allies would pay a military price not seen since World War II, with massive losses of aircraft, ships and personnel. Taiwan, even if it managed to resist, would be deeply damaged as a country and as a global economic engine, dragging the world into a prolonged crisis. The island that weighs the most. All this explains why Taiwan is, by far, the increased geopolitical risk of the planet at this time and a strategic priority, surely far above scenarios like greenland. It is not about territory, or not only, but about credibility, balance of power and stability of the international system between two superpowers. And, on that board, every gesture of ambiguity counts, and every sign of weakness can bring closer a conflict that no one would win on paperbut whose consequences would affect everyone.

How Venezuelan crude oil became a risk

by

On December 14, 1922, the Los Barrosos-2 well in Venezuela exploded into a 60-meter geyser of crude oil that took a week to stop. As CNN remembersthat ecological disaster set the country on a path of dazzling wealth and political turmoil that has led, a century later, in the capture of President Nicolás Maduro by US forces. While in Washington they celebrate the “Donroe Doctrine”in the control centers of the Cartagena and Bilbao refineries there is a different tension. For Spain, Venezuela is not just foreign policy news; It is an economic black hole of 1,160 million euros. A deficit out of control. The commercial relationship between Spain and Venezuela has gone from being a balanced exchange to a financial abyss. According to data collected by El EconomistaIn 2024, Spain registered a trade deficit of 1,160 million euros with the Caribbean country. It is triple that in 2022 and the highest figure in the last 18 years. The cause is an alarming asymmetry. While our sales barely reach 230 million euros, our purchases have multiplied by 22 since 2021. Spain has become Venezuela’s fourth best customer in the world, behind the US, India and China. However, it is not a diversified purchase but 94.59% of what we import is oil and derivatives. Repsol: the jewel exposed on the board. If there is a proper name in this conflict, it is Repsol. According to Expansionthe Spanish oil company is the company with the most money at stake in the area. Venezuela is not just another asset; is its second largest source of reserves tested in the world (256 million barrels), only behind the United States. This represents almost 15% of the company’s entire underground treasure. But the risk is not only what is underground, but what is owed. Repsol’s equity exposure due to commercial debts of the state-owned PDVSA amounted to 330 million euros in June 2025. In addition, the Spanish oil company extracts 33% of the gas consumed by Venezuela. As the same source points out, without Repsol gas, the Venezuelan economy would come to a standstill, but without Venezuela’s legal security, the Spanish company’s balance sheet could suffer a “hole” of more than 13 billion euros in reserve valuation. The paradox of “heavy food.” Many wonder why Spanish companies insist on a country with obsolete infrastructure. The answer is technical. Venezuela’s oil is “extra-heavy”, dense as tar. Ironically, the oil that the US extracts through fracking is “too good” (light). To produce diesel and asphalt efficiently, Gulf Coast and Spanish refineries need to blend their light crude with Venezuela’s dense “stuff.” However, this is a “gas station without hoses.” The crude oil arrives “dirty” (with excess salt, water and metals) because PDVSA has dismantled pipelines to sell them as scrap. This turns refining into an expensive and risky process that only companies with decades of roots, such as Repsol – since 1993 – dare to manage. The wall of 100,000 million. Trump’s optimism, which already mobilizes private funds of 2 billion dollars led by former Chevron executives, clashes with technical reality. In fact, analysts consulted by The Wall Street Journal They warn that there will not be an immediate miracle. Rebuilding the sector requires an investment of $10 billion a year for a decade. The infrastructure is so deteriorated that PDVSA acknowledges that its pipelines have not been modernized in half a century. The total repair bill amounts to $100 billion. The Trump factor and the “Donroe Doctrine.” In an analysis by market expert Robert Armstrong highlights a paradigm shift: Trump has shown that his geopolitical ideology is above market stability. By capturing Maduro, he has put his legacy at stake for the objective of controlling the energy flow from Alaska to Patagonia. This movement a priori benefits Repsol, which had been negotiating for months to avoid the export blockade. However, the risk is that the US will prioritize the landing of its own colossi (Exxon, Chevron, ConocoPhillips) displacing the European partners that, such as Repsol or the Italian Eni, stayed when the Americans fled during Chávez’s expropriations. A prize with small print. Spain has before it a historic opportunity to recover its investments and lead the reconstruction, given its historical roots. But the 1.16 billion “hole” is only the symptom of a deeper illness: dependence on an asset that requires massive investment to be profitable in a world that is already beginning to say goodbye to fossil fuels. Venezuela continues to be the largest gas station in the world, but today it is a dilapidated facility whose repair bill threatens to stain the balance sheets of the large Spanish company if the transition is not “surgical.” Image | Pexels and Repsol Xataka | Venezuela has shown that the US can find anyone no matter how hidden they are.

V-16 beacons run the risk of being left without connectivity if their manufacturer goes bankrupt. Don’t worry, there is a solution

by

You may have read it on social networks: you buy a connected V-16 beacon, you go years without using it and, before you know it, the company that sold it to you has gone bankrupt, has stopped paying for its servers and now you have a nice paperweight because, without connectivity with DGT 3.0, that beacon has become illegal. It’s true? No. Plain and simple. When we buy a connected V-16 beacon, the manufacturer assures us that the connectivity is guaranteed for at least 12 years. The manufacturer may offer more connectivity time, as an incentive to purchase, but it cannot offer less. This, like the luminosity of the beacon or the 30 minutes that it must be in operation for at least, is one of the demands that Traffic has set to manufacturers so they can sell their beacons and we let’s buy them with enough peace of mind to be following the rules. Sure, but… what if the company goes bankrupt? It is one of the questions that some users have asked and that has been answered by accounts on social networks like Twitter. It is stated that when a connected V-16 beacon is activated and the required 100 seconds pass, the following process is launched: Protocol A: the beacon sends the data exclusively to the manufacturer’s servers Protocol B: Data leaves the manufacturer’s servers and is forwarded to the National Access Point for Traffic and Mobility Information which is where all activations and any other type of emergency are reflected. The response points out that, in the event that the manufacturer stops selling the connected V-16 beacon, the connection would be broken and therefore we would be left with a luminous paperweight because without connectivity that light is not legal. Insured. To confirm these details, we have contacted some of the companies that manufacture or sell these types of beacons. César Basterrechea explains to us from Atressa Automotivewho have their own beacons, that the information is not true and clarifies what would happen if their company went bankrupt and stopped paying for the beacons. First, he points out, the manufacturer has to register in DGT 3.0 and request a connectivity license. When this requirement is met, the following happens: “My operator sends me the data generated by one of my beacons through an APN and which is protected within a private VPN, the information reaching my Cloud once received, we send it through a VPN with a digital certificate to the DGT 3.0. If my company closed tomorrow, my operator would redirect the data emitted from my beacons to another APN of its own and through its own VPN it would send the data to the DGT cloud” With these words he explains, therefore, that it is the operator that offers its support if the company stops paying for the servers and, therefore, cannot offer the service. They confirm it to us. Asked to the other party, the answer is the same. In Xataka We have contacted Orange, an operator that offers connectivity in different connected V-16 beacons on the market. The company confirms the above, although it points out that, exactly, it is not that the operator keeps the servers of the bankrupt company, it only guarantees that the signal reaches DGT 3.0. “The communication architecture has been defined so that there are two ways to send the data to DGT 3.0: through the manufacturer’s cloud services (which must always be used if there are no incidents) or directly from the operator if the manufacturer’s cloud service is not operational (manufacturer bankruptcy or massive drop in its cloud service)” It’s not easy. The truth is that although we have confirmation from this beacon manufacturer And getting there is not easy. In the Resolution of November 30, 2021 which details the requirements that a V-16 beacon must have connected to be valid, it specifies that the manufacturer must have support to offer the service if it cannot be performed, but nowhere does it specify whether this company should be the operator, as Atressa Automotive tells us. This text explains the above-mentioned details of protocols A and B. Subsequently, the following is stated: The implementation of a device with these characteristics requires having a standard channel and a common language. Additionally, defining this standard also makes it easier for a third party to perform these functions if necessary due to the existence of a problem in the information systems of a manufacturer. The data model that the messages that V-16 devices send to their manufacturers’ information services must comply with is defined below. a hoax. Although with the connected V-16 beacons we have had a lot of controversy and we know that there are even those who has demonstrated cybersecurity risksThe truth is that this time we are facing a hoax. The DGT has actively repeated that when we buy a connected V-16 beacon we are guaranteed access to DGT 3.0 for 12 years. And although the protocol does not clearly detail whether a specific company must take charge (operators, other manufacturers…), it does specify that it must guarantee backup to keep the service active.

‘Avatar 3’ is going to be a movie so disproportionately expensive that it runs the risk of destroying and losing money

by

‘Avatar: Fire and Ash’ is already, as has happened with all previous installments of the franchise, one of the most anticipated films of the year. Each new installment breaks box office records, and yet James Cameron’s statements are more pessimistic each year about the continuity of the series. Are you sure that ‘Avatar’ is as good a deal as it seems? We snooped into his finances. The paradox. ‘Avatar: Fire and Ashes’ arrives wrapped in an economic paradox: its production budget exceeds 400 million dollarsa figure that places it among the most expensive films ever filmed. And yet, its own director is not clear if the business is worth it. Cameron has been unusually frank about his franchise’s finances and he put the question bluntly: “Will we make money on Avatar 3? Surely some. But the real question is what kind of profit margin there will be, if any, and whether that will be enough of an incentive to continue in this universe.” The wild mathematics of break-even. The arithmetic of ‘Fire and Ashes’ defies standard Hollywood logic. With 400 million in production expenses and a marketing budget that analysts place between 100 and 175 million, it would need to exceed $1 billion at the box office simply to break even or break evenaccording to the more or less assumed industry rule that a film must gross 2.5 times its production budget to be profitable. The case of ‘The sense of water’. The previous installment of ‘Avatar’ gives us some previous lessons on the subject. The sequel cost more than $1 billion in total costs: $400 million in production, another $400 in global marketing, $300 million in shares for Cameron and producer Jon Landau, plus cast salaries, residuals and general expenses. Cameron was not exaggerating when declared that ‘Avatar 2’ was “the worst business case in the history of cinema” and that it needed to become “the third or fourth highest-grossing film of all time” simply to not lose money. The film fulfilled that apocalyptic objective: raised 2,320 million and finally generated 531.7 million net profit. But that deceptively solid figure hides a crucial detail: The studios do not receive all the money from the box office. Movie theaters take approximately 50% of US domestic revenue, 40% from international markets, and up to 75% in China. That is, of those 2.32 billion, Disney actually received just over 1 billion. The rest stayed at the box office. The crisis of inflated budgets. ‘Avatar’ is one of the most visible symptoms of a disease that affects all of Hollywood. The industry has a systemic problem of out-of-control budgets, which affects such well-known films as ‘Star Wars: The Rise of Skywalker‘ ($490 million), ‘Jurassic World: Dominion’ (584 million) or ‘Mission: Impossible – Deadly Sentence: Part One’ (400 million). A analysis of the causes It leads us to multiple factors that explain this phenomenon: inflation has increased the value of the dollar by 15% since 2020, making all aspects of production more expensive. But in addition, streaming platforms altered the economy of stars, accustoming them to higher initial charges, demands that they later transfer to traditional productions. And there is also a visual effects arms race: franchises like superheroes try to surpass each other in spectacularity, and infect the rest of the blockbusters. For this reason they are films that “might not make money even with objectively decent box offices.” The unique case of ‘Avatar’. James Cameron invests in developing pioneering technology that then benefits the entire industry: the underwater motion capture that Cameron and Weta FX took a year and a half to perfect for ‘The Sense of Water’, now reduce costs for the sequels being already invented. But the budget escalation is relentless: ‘Avatar’ cost between 237-280 million, ‘Avatar 2’ between 350-460 million and ‘Avatar 3’ exceeds 400 million. The franchise is a guarantee of box office success, but the profit margins are worryingly narrow. In Xataka | Cameron’s ‘Titanic’ was going to be a flop.

Prickly pears are at risk of becoming extinct because no one wants to be a prickly pear anymore. Castilla y León wants to remedy it

by

His image is iconic, unmistakable. Capes, doublets, ribbons and patches, with guitars and bands in their hands and setting the rhythm around the campuses. The university prickly pears are part of the cultural heritage of Spain and as such the Junta de Castilla y León wants to protect them, which just declared tradition an Asset of Cultural Interest (BIC) of an intangible nature. The measure comes at a particularly delicate moment: with the prickly pear Vivabut stalked by “threats”. What has happened? That Castilla y León has just declared the university prickly pears Asset of Intangible Cultural Interest. In reality, the regional Government Council made the decision several weeks ago, November 27but it had not been consolidated until now, with your publication in it Official State Gazette. Why is it important? To begin with, because it represents public recognition of a cultural tradition that dates back centuries and will now have a new institutional veneer. Among other issues, the BIC label should make it easier for groups to promote themselves. The declaration as immaterial BIC also places the focus on another fundamental issue: the state of health of university students in Spain. At the end of the day, the Junta de Castilla y León itself recognize that one of the objectives of the measure is to “protect the uniqueness” of a tradition that, he insists, remains “alive” and “integrated” on the campuses. Not everyone shares his optimism. From Culture they warned not long ago that the prickly pears face “threats”. Why declare it BIC? The Castilian Government is clear about it: claims “the roots” of the prickly pear in the region and remembers that the tradition arose in the heat of some of its first universities, such as that of Palencia, Salamanca either Valladolidwhich trace their origins to the 13th century. “This has allowed the tradition to take deep roots in the region from an early date,” collects the BOE announcementin which he presents Salamanca as the “cradle of the prickly pear.” Since then the groups have gone through multiple ups and downs. The prickly pears started among the humblest university students of the late Middle Ages, young people who played in exchange for food or a few coins, and remained active throughout the following centuries. In the 19th century they were on the brink of disappearance, but they gained renewed momentum thanks to the Romantic movement. The Civil War threatened its survival again, but the tradition was reinforced during the 40s, 50s and especially between the 60s and 70s, when Spain opened up to tourism that found in those young people who dedicated themselves to singing dressed in capes and ribbons a “picturesque symbol of Spanish student folklore.” Already in the 1980s and 1990s the first female groups were consolidated. And how are they now? The Board assures that “the presence of university prickly pears” covers the entire region, giving shape to “a living mosaic.” “Castilla y León is home to between 20 and 30 active or recently active university tunas, distributed throughout all its provinces,” celebrate the Castilian-Leonese Government before specifying that this estimate includes all types of groups, male, female and those known as fortiesformed by ancient tunos. How are your health? It depends on the source we consult. In June, Ernest Urtasun’s department published a report in which, after emphasizing the cultural and historical interest of these groups, he issues a warning to sailors: “The university prickly pear faces risks and threats derived above all from the aging of its members due to the lack of incorporation of new members in the existing groups, which results in a decrease in their number.” The comment is actually included in an official file which aims to declare the prickly pear “representative manifestation of the Intangible Cultural Heritage.” What are the prickly pears like today? That’s the key. The Country concrete that of the 150 musicians that make up the Law tuna of the Complutense University, only 15 are under 30 years old. “In the end it is a tradition that is championed by people who are not university students,” recognize one of its members. Another veteran of a prickly pear in Valladolid admits that “many fewer performances” are carried out than before. “There is no longer so much influx of people who want to join, whether due to musical tastes, the loss of economic support, fashions or the appearance of other groups, such as charangas,” reflect. “What I am clear about is that tuna continues to be a way to meet with friends who share a taste for music, creating bonds that can last a lifetime.” The situation also varies from one area to another in Spain. four years ago The Galician Post explained that in Santiago de Compostela, another of the main university cities in the country, only one prickly pear remained intact (there are other initiatives), that of Law. Of course, based on musicians who for the most part were no longer linked to the university. The Galician newspaper pointed out, however, that the trend was somewhat different in the southern half of the peninsula.

the science behind a geological risk that repeats itself every 1,200 years

by

Although the tsunamis seem like effects that are reserved for the Japanese coasts, the reality is that Spain He also has many ballots to suffer an event of this magnitude on our coasts. Cádiz is one of the locations with the highest risk of suffering a tsunami in Spain, and the authorities wanted to verify that the emergency and response systems they work in case this type of event occurs at any time. In order to verify this, the authorities carried out a drill in mid-November in which the ES-Alert systemseveral schools and all emergency services. And given this great display, the question is mandatory: what are the chances of a tsunami occurring in Cádiz? Cádiz is at the center of this simulation because it is the area with the greatest danger from tsunamis in the country, due to the history behind it and the seismicity of the Azores-Gibraltar area. For this reason, the Junta de Andalucía has prepared a Emergency Plan for the Risk of Tsunami (PEMA) and has chosen Cádiz for the largest tsunami simulation carried out in Spain. Because. In the past, geological records indicate that at least five large tsunamis have occurred in the Gulf of Cádiz in the last 7,000 years. All of these associated with megaearthquakes at the plate boundary between Africa and Eurasia. Added to this is the historical reference: the tsunami linked to the Lisbon earthquake of November 1, 1755which completely flooded Cádiz and part of the Andalusian coast with waves of several meters in a matter of dozens of minutes. The paleoseismology works of the CSIC and several universities place the recurrence interval of these events between 1,200 and 1,500 yearslong enough to be socially forgotten, but too short to be ignored in risk planning. This places the southwest of the peninsula as one of the most exposed areas in Europe to tsunamis, despite the fact that the “perceived risk” on the street has historically been very low. And this is precisely something that has been analyzed in the layers of sand and marine remains left inland and that gives us information about what happened thousands of years ago. Although logically always with a time frame that is approximate. Why now. The fact of doing the simulation in this month of November may make us think that scientists have found evidence that a large tsunami is coming to Cádiz, but nothing could be further from the truth. What is happening in this case is that a risk that has been known for a long time and for which, until now, hardly anything had been tested on a large scale, is being taken more seriously. That is why this scientific evidence that tells us about the real risk that exists in this case on the coast of Cádiz has been transferred to the regulations. In 2015, the Basic Planning Guideline for Civil Protection against the Risk of Tsunamiwhich recognizes the Gulf of Cádiz as a critical area where the expected wave height exceeds 0.5 meters. A framework that is not limited to pretty maps, but defines decision guidelines according to magnitude and location of earthquakes, chains of command, warning protocols and response time objectives, with the National Geographic Institute, AEMET and the future SINAM network as input sensors. What has been simulated. In this case, Cádiz has simulated an earthquake with an approximate magnitude of 7.5-7.6 to the southwest of Cape San Vicente, very similar to the one in Lisbon in 1755 and which generates a tsunami that points directly to the western Andalusian coast. In this scenario, the propagation models estimate between 45 and 60 minutes from the activation of the alert until the arrival of the first wave from Cádiz, which in practice is the clock with which Civil Protection works. The objective of the exercise was to virtually save as many people as possible in that one-hour window: horizontal evacuation to non-flood areas, vertical evacuation to high floors, beach and port rescues, protection of cultural assets and management of damaged buildings were tested. On paper, all this already existed in manuals and maps; What was missing was to see how a real city behaves when a tsunami warning sounds in the middle of a work morning.​ Images | Matt Paul Catalano In Xataka | There are scientists deliberately causing earthquakes in the Alps and they have a good reason for it

There are eight million Airbnbs, but only one where the disconnection is so extreme that there is fine print: risk of death

by

At the beginning of the year, the figure by Bryant Gingerich began to circulate in many media. In a secluded corner of the Ohio wilderness, Gingerich, a 34-year-old engineer, seemed to have found an opportunity to transform his professional life by converting a simple cave in a successful vacation rental business. However, if we talk about places far away from the world, none like the one in this story. Stay at the extreme. I told the story a few days ago BBC. In the Kulusuk Fjords of eastern Greenland, the Floating Glacier Hut It has established itself as one of the most remote accommodations, if not the most, in the world. The cabin, installed on a floating hexagonal platform and anchored to the surrounding rocks, it is located in an area where the distances between settlements are enormous and the human presence is minimal. Access is made only by boat and the infrastructure responds to the idea of ​​offering a space completely removed from any urban dynamics, in a territory dominated by glaciers, icebergs and an unpredictable climate. This approach fits with the rise of the so-called as “quietcations” and hyper-remote destinations, which seek to satisfy the growing need for total disconnection that many travelers express in the face of the accelerated pace of daily life. Disconnect without technology. The cabin dispenses with the internet and reduces outside communication to a satellite phone, which forces us to live real isolation throughout the stay. The Finnish-made module is thermally insulated and has a glass roof that allows you to observe the polar sky and phenomena such as the northern lights without leaving the interior. The equipment it’s basic: a small stove, a toilet, a minimal kitchen area and a double bed. The lack of a shower is part of the design, and some visitors resort to quick dips in the frozen sea to clean themselves. This austerity is proposed as a central feature of the experience, focused on the observation of the environment and sensory immersion without digital interference. Views from the accommodation Caution and logistics. Extreme isolation coexists with reasonable vigilance against the risks inherent to the Arctic. According to the local guide Nicco Segretoresponsible for the project, the cabin acts as an effective refuge from potentially deadly fauna like polar bears (there is a sign that warns you before entering), as long as you stay inside. However, the operator warns that weather conditions may prevent the arrival of the boat in charge of transporting guests, an element that is part of the operational reality in the region. The landscape offers opportunities for activities such as glacier hiking, exploring ice caves formed by subglacial rivers, and ice fishing through a small hole prepared in the structure. These excursions show the dynamics of ice and the visible effects of melting, reinforcing the educational value of the trip. A tourist project. Secret discovered a decade ago a glacial cave that today is part of the activity offerand that discovery was the origin of his initiative to develop low-footprint tourism in the area. In addition to generating employment in the Tasiilaq community, the project aims to attract travelers interested in geology, the behavior of ice and the magnitude of the polar landscape. The Floating Glacier Hut It is the initial phase of a broader plan that includes a future retirement of greater capacity, Vision Lodgeaimed at structured stays of several days. The accelerated retreat of the glaciers, visible even year after year, becomes a central component of the experience, which allows us to observe climate changes on a human scale. An exclusive model. The stay, designed for two people, has an approximate cost from 1,000 to 1,200 dollars per night and includes private boat transfers, dinner prepared by the guide himself, and breakfast. Despite the price, remembered the BBC that the accommodation It has received very positive reviews for the combination of isolation, landscape and silence, elements that guests point out as difficult to find in other destinations. Thus, the general perception is that it is an experience designed for those who seek to completely disconnect (from humanity and devices), observe the environment without filters and face a slower pace, where nature is the central axis of the room and the passage of time seems to acquire another scale.

High speed in Madrid is at risk of collapsing. And that’s why Adif wants to send her to Parla

by

Parla has 134,833 inhabitants, 24.43 km² in area and one goal: to become the nerve center of high speed in the south of Madrid. The idea was presented yesterday by Óscar Puente, Minister of Transport, and is part of the profound renovation that the Government wants to carry out on the high-speed line between Madrid and Barcelona. The plans. Announced yesterday by Puente: a Madrid-Barcelona in less than two hours. That is the goal and the big headline. At the moment what we know is that two feasibility studies have been requested. They will study the possibility of introducing improvements in the infrastructure so that trains can reach 350 km/h top speed and both cities can join in less than 120 minutes. The investment should be reflected in “more services, less time, more users, more territorial structure and flexibility of exploitation, according to Puente’s own words. For this, the construction of two new stations will be key, which will also be the key to introducing two new variants at the entrance to both cities. Parla. It would become the reference for the municipalities in the south of Madrid. And the construction of a large caliber station in the southern zone would not only impact the more than 130,000 residents of the municipality. The key is in everything that is nearby: Getafe, Leganés, Fuenlabrada or Pinto. Alcorcón and Móstoles are further away but there are connections with Cercanías. From Transport they say that Parla has “an area of ​​influence of more than 1.26 million inhabitants and in which, within a range of 15 minutes, 4.7 million people would have access and in less than 1 hour, about 6 million potential users.” In these moments, and if no delays or breakdowns occurthe connection between the Parla and Atocha Cercanías stations is covered in 29 minutes. And it takes 33 minutes to get to Sol station, in the heart of Madrid. Decongest. It is the last objective of the new station. If built, the idea is to offer an alternative to intern services. That is, those who travel from Barcelona to Seville directly. These trains would need less time to travel the distance since they would travel fewer kilometers and could travel faster as they would not have to deal with speed reductions at the entrance to the city and passing through Atocha. Besides, Puente pointed out in his speech that with this new station the station can be used as an intermediate stop on the Madrid-Seville and Madrid-Levante services (its neighbors would not have to go to the center of the capital to return back having boarded the high-speed train) and it can serve as an alternative station in case of incidents. Right now, Transport assures, 250 trains circulate through Madrid or its surroundings. With this variant an alternative would be created to the high-speed route already existing between Madrid and Andalusia or Levante. In addition, it would improve the service for the increase in traffic expected with the improvements in the Extremadura corridor. Parla, you are not alone. Parla’s action, as we said, is not the only one that Transport plans to reduce the time between Madrid and Barcelona. With the same arguments, the idea is to create a new station near Barcelonaspecifically in El Prat de Llobregat. The idea is that this new station would allow the Madrid-Barcelona-French border high-speed train to connect with the Josep Tarradellas Barcelona-El Prat airport. Regional trains would also stop at this station through the corresponding adaptation of the lines. The other action in Catalonia involves linking the Lleida-Pirineus station with Barcelona with a new line that would enter the city through La Sagrera, north of Barcelona. In this way, trains would not necessarily have to pass through Camp de Tarragona, freeing up part of the traffic that already circulates there and, therefore, offering a new variant to Barcelona very similar to that of Parla in Madrid. Many trains, little investment. Although the study of these actions has raised some controversy when it is understood that other Spanish roads still need significant improvement to lighten travel times, the truth is that investment in Adif’s infrastructure has been requested for a long time. It must be taken into account that both alternatives in large cities, and especially south of Madrid, represent a good escape route to decentralize the network. The arrival of Ouigo and Iryo has exponentially increased the number of trains on the tracks but they face the problem of Adif has not invested enough money to absorb traffic. own Puente assured last August that “6 trains circulated per day on the Madrid-Seville line, in each direction. Today, 289 trains circulated at the Torrejón de Velasco point on the Madrid-Seville high-speed line (…) When there is an incident you have 25 trains in both directions within a radius of one hour.” Photo | Smiley.toerist and Google Maps In Xataka | A Spain literally at two speeds: while the Madrid-Barcelona AVE goes at 350 km/h, the rest of the network languishes
