disaster

The Milky Way has been in the sky for billions of years. It took a natural disaster for the residents of Los Angeles to see it for the first time

by

January 17, 1994. The San Fernando Valley trembled under a large earthquake of magnitude 6.7 that shook the city of Los Angeles with terrible severity. As is normal after a disaster like thisthe emergency lines were soon filled with calls from terrified neighbors. There were many common warnings, but there was a much more curious call which was repeated ad nauseam. That of a lot of neighbors scared by the enormous silver strip that had opened in the sky. What they saw, far from being something dangerous, was a clear sign of the light pollution that already covered Los Angeles 30 years ago. It was just the Milky Way. In reality, what these neighbors saw was neither more nor less than the Milky Way. Many of them were not used to traveling outside big cities, so they had not seen our galaxy crossing the sky in their entire lives. This is precisely why this true story is often used to raise awareness about the risks of light pollution. Why is it not seen? Artificial light from streetlights, monuments or illuminated shop windows is reflected and dispersed in the atmosphere, so that it illuminates the background of the sky. Normally, we see stars because there is a great contrast between them and the dark sky. However, this scattered light almost completely destroys said contrast. From Earth, the Milky Way appears as a very faint band of light. Therefore, if there is not enough contrast it is practically impossible to see it. It’s still there, but it’s hidden from our eyes. The more pollution, the worse. The suspension of particles in the air can cause artificial light to scatter even further. Therefore, the problem in large cities, like Los Angeles, is twofold. On the one hand there are many streetlights and other luminaires and on the other hand there is usually a lot of pollution. It is normal that so many people have never seen the Milky Way. Getting worse. This event took place more than 30 years ago. Although today there is more awareness about the problem of light pollution and the City Councils of some cities design lighting projects advised by astronomers and other experts, the situation has not improved. In fact, currently is calculated that 80% of the world’s population lives under light-polluted skies. Using the striking case of the Milky Way as a reference, a study published in 2024 point because 60% of Europeans and 80% of Americans have never seen the Milky Way. The case of people who believed that the sky had cracked is just an anecdote. However, the reality is that the heavens are no longer what they were. If the problem of light pollution is not solved, future generations will not be able to enjoy many of the spectacles that the sky has given us.

In 1985, on the verge of being defeated by Pepsi, Coca-Cola changed its ancestral formula. The result was a disaster

by

Coca-Cola had been the reference soft drink around the world for decades, but in the early 80s a very tough competitor had emerged: pepsi. The firm had been gaining more and more followers with advertisements in which they participated Michael Jackson, Michael J Fox either Cindy Crawfordand its success did not stop growing thanks to a spectacular advertising campaign called “The Pepsi Challenge”. Those ads seemed to show that people preferred the taste of Pepsi, and Coca-Cola managers, scared by the threat of being forgotten, decided to change the formula and create the so-called “New Coke.” That was a disaster and Coca-Cola ended up returning to its original formula. The Pepsi challenge was as simple as it was effective. The people who participated did a “blind tasting”: there were two glasses with unidentified cola, one with Coca-Cola and the other with Pepsi. In appearance they seemed the same, and behind them were the bottles with which each glass had been filled (or hidden under some paper cylinders). The result according to the advertisements was always himself. The taste of Pepsi won time and time again. Coca-Cola executives, who saw how their market share was constantly declining, began a gigantic project: the creation of a “New Coca-Cola” (New Coke) that would see its recipe modified for the first time since the creation of this drink in 1886. What happened The modification of the recipe was evaluated with market studies that were promising: the new Coca-Cola, sweeter, beat both the old Coca-Cola (the original) and Pepsi. Everything seemed to show that Coca-Cola had its winning drink. That made the company announce “New Coke” with great fanfare on April 23, 1985. Initially the reception was good, but criticism soon began to arrive, which increased: a lot of people wanted the old Coca-Colaand surveys conducted shortly after the launch showed how only 13% of people preferred “New Coke.” Coca-Cola ended up producing the original recipe again, which it called “Coca-Cola Classic” just two months after that launch, and some time later it directly stopped manufacturing its “New Coca-Cola” to stay with the classic, which also lost that adjective. Everything remained as at the beginning, but with a spectacular marketing failure and development in which the firm had invested 100 million dollars. Still, Coca-Cola recovered after the disaster. That attempt to compete, although a failure, seemed to resonate deeply with consumers, especially when Coca-Cola recognized its mistake and offered the “old Coca-Cola” again. By the end of 1985, Coca-Cola Classic was outselling New Coke and Pepsi. What happened? One of the problems was pointed out by Malcolm Gladwell in his book ‘Intuitive Intelligence: Why do we know the truth in two seconds?’ (‘Blink: The Power of Thinking Without Thinking’). In it he explained how the failure was in the nature of the blind tastings, based on “sips.” People, he explained, reacted positively to the sweeter taste of Pepsi when they only tried a sip, but that taste ended up being worse when you drank an entire can, and that is what according to Gladwell Coca-Cola failed to understand in its tests. The original Coca-Cola recipe proposed a much more appropriate balance for the capacity of the cans and bottles of this soft drink. At Coca-Cola they also tried to investigate what had happened, and the conclusion of those in charge was that they underestimated the public reaction of people who rejected the change. The response generated by that launch of the “New Coca-Cola” was astonishing, and signature collections and movements against the new recipe were organized that united many people in an unprecedented campaign. Of course: New Coke kept winning those blind tastings. It didn’t matter: the one that really won was Coca-Cola, whose current quota in the soft drink market is 44% in the United States, while Pepsi’s is 26%.

After the Titan millionaire submarine disaster, China plans to take more rich tourists 1,000 meters under the sea

by

The depths ofto Mariana Trench or exploration from the deep ocean It has always been a thing for scientists and remotely controlled machines. China wants it to stop being so and already has an ambitious plan in motion: taking wealthy tourists to 1,000 meters deep, where sunlight does not reach and where there is no turning back for an engineering failure. The project comes three years after the Titan tragedythe OceanGate submersible that imploded in June 2023 while I was visiting the remains of the titanic in which its five occupants died. Far from stopping its efforts, China is moving forward with a proposal that, unlike the Titan, is backed by decades of naval engineering developed with the support of China. Four highly sought-after seats. Ye Cong, director of the China Naval Scientific Research Center, counted to ChinaDaily that “after more than four years of research, engineers have finalized the structural design” and that, once the prototype is built, “they will carry out sea trials and then improve the design based on the results.” The submersible will have enough space to accommodate four peoplepilot included, so, to begin with, the availability of places is very limited. This shortage of vacancies is expected to contribute to skyrocketing prices for filling each seat. One of the most complex problems of the small submarine has already been solved: the panoramic viewfinder. Your designers they describe it as “one of the most difficult structural codes to decipher on a deep-sea submersible.” And it makes sense since at 1,000 meters deep the pressure is about 100 times greater than on the surface, and that window has to withstand it without giving way. An unprecedented leap into the abyss. This is not the first submersible that Chinese engineers have operated. However, such andhow do they count in South China Morning Post The new projects that are being tested far exceed the depths at which current submersibles operate, which do not go below 20 meters deep. They are used for lakes, reservoirs and shallow coasts, so going from there to 1,000 meters is multiplying the operating depth by 50. The same naval engineering center that is now building this new generation of manned mini-submarines already built The Huandao Jiaolong 1 and 2, two tourist submersibles with capacity for seven passengers and a limit of 40 meters. However, on that occasion, immersion operations were suspended due to regulatory restrictions, but everything learned then has been applied to the new design. China plunges into the field of underwater exploration. The West has been designing submersibles for decades for deep dives. Companies like Deep RoverTriton and U-Boat Worx have been manufacturing submersibles over 1,000 meters since 1985 and until now had no Chinese competition in that segment. The new project developed by the China Naval Scientific Research Center changes that scenario supported by the previous experience of the Jiaolongthe Deep Sea Warrior and the Fendouzhe, three ships that last year completed more than 300 dives around the world and accounted for more than 50% of all manned deep-sea expeditions on a global scale. Ye Cong assured the Chinese news agency that the submersible: “will be a valuable asset for cruise lines, high-end tour operators and oceanographic researchers. It will offer the most demanding travelers an unforgettable experience in ocean exploration.” The prototype should be ready before the end of 2026, with the commercial debut expected before 2030. Much more than a tourist “toy”: it is a key strategy. This submersible is not just a mere product intended for tourist use of millionaires with adventurous concerns. It is part of China’s strategy to become strong in the blue economy, the sector of economic activities linked to the sea, a developing sector in which China seeks to play a leading role in the future. The Asian giant already leads manned deep-sea exploration and wants that this technological advantage is amortized in the form of a private business for their companies. After the Titan catastrophea good part of the luxury underwater tourism industry came to a screeching halt. China is the first to step on the accelerator again in this area, and this project is supported by State resources, which gives it a considerable advantage over projects that, like the Titan, are developed with private funds and investors.

the Chernobyl nuclear disaster, illustrated in fascinating cartographies of the disaster

by

On April 26, 1986, reactor number 4 of the Chernobyl nuclear power plant, in the former Ukrainian Soviet Socialist Republic, exploded during a low-power safety test. The accident released an estimated amount of radioactive material of 400 times greater than that of the Hiroshima atomic bomb, according to the International Atomic Energy Agency. The RBMK-1000 reactor involved had no containment structure, so radioisotopes such as iodine-131, cesium-137 or strontium-90 were freely dispersed into the atmosphere for ten days in a row, until they extinguished the graphite fire on May 5. The management of the accident could clearly be improved: the authorities ordered the evacuation of the nearby city of Pripyat 36 hours later and the world found out when Sweden detected radiation at its Forsmark plant on April 28. Ten years later, independent Ukraine published the Atlas of the Chernobyl Exclusion Zonea set of large-format graphic resources prepared by the state cartographic agency. As explains data journalist Attila Bátorfywas the first serious attempt to map the radioactive impact of the disaster on the soil, air and ecosystems and a large number of scientific professionals from entities such as the Ukrainian Academy of Sciences or other research institutes dependent on the Ministry of Ukraine for the Protection of the Population from the Consequences of the Chernobyl Nuclear Power Plant Accident participated in its preparation. Now it is available to anyone thanks to the digitized version available on Ecogisstorage. The atlas contains different cartographic blocks. One of the first and essential to understand evolution are the weather maps of europe the days during the active phase of the accident and show what the atmospheric situation was like afterwards, with isobars, atmospheric fronts or wind direction for each day. This is the basis of everything because without reconstructing how the air circulated those subsequent days it is not possible to interpret other pollution maps. The radioactive cloud followed erratic trajectories conditioned by the weather fronts, which explains why countries such as Sweden, Poland or Austria received significant deposits while closer areas were relatively less affected. Daily synoptic weather maps of Europe during the active phase of the Chernobyl accident To analyze the meteorological influence on dispersion in Ukraine, different graph formats are used, such as bars, wind speed and direction diagrams, or this one that goes under these lines: the radiological wind rose, which shows the amount of material released in each direction of the mean wind in the atmospheric boundary layer. Each line on the diagram represents the mean wind direction in the atmospheric boundary layer at a given time, with its date noted, the length indicating the magnitude of the radioactivity released. At first glance something can be seen: The dispersion was neither uniform nor radial.but tremendously asymmetrical. Thus, some fronts dragged pollution northwestward, towards Belarus and Scandinavia, while others diverted it to the south and west of Ukraine. Vector diagram of radioactivity emissions (in Bq) constructed for the average wind direction in the atmospheric boundary layer. The effects of the Chernobyl disaster, on maps Under these lines This is the most important map by far: that of Cesium – 137. Why is it important? Because due to its characteristics, Cs-137 is the radiological tracer par excellence, which allows directly showing the permanent chemical trace of the accident on the territory. Retrospective estimation map of soil contamination with cesium-137. At a scale of 1:200,000, it shows the deposition density of Cesium – 137 in the soil on May 10, 1986, reconstructed in retrospect. The pollution isolines draw a tremendously asymmetrical patch, with an absolute maximum concentrated in the north and northwest. There is also a second important spot in the south, following the course of the Pripyat River. The rest show decreasing levels with distance in a radial manner. Groundwater transport route map The previous one may be the most striking and without a doubt it is the one that has been most widely disseminated, but the most disturbing in the long term is the map of transport routes in groundwater because it quantifies the long-term risk of water pollution. Cs-137 is easily seen and measured, but strontium-90 moving silently through the aquifers toward the Dnieper, which supplies water to millions of people, is an invisible problem. This 1:200,000 scale map is the only one in the atlas that attempts to quantify this risk with real flow velocities, showing the probable migration trajectories of radionuclides through the aquifers. The arrows point predominantly to the south and southeast, in the direction of the Dnieper. Gamma dose map The map you see just above also has a scale of 1:200,000 and shows the gamma radiation dose power in μR/h (microroentgen per hour), measured 1 meter from the ground. Yes, the above maps are important to describe the severity of the problem, but the gamma dose rate map is essential for decision making: who can enter the area, for how long and what routes are passable. It was the work tool to access the area because it is the map for evaluate exposure dose of the population and the personnel who worked in the area.

Long before Real Madrid, the Roman Empire had already invented VIP boxes. And they ended in disaster

by

In the first century, the emperor Nero ordered that some shows will include giant awnings to protect the most privileged attendees from the sun, while the rest of the public endured the heat in the upper stands. That seemingly trivial difference reflected the extent to which the experience of attending an event was already marked for money and status long before modern stadiums existed. Show business in Ancient Rome. Long before modern stadiums like the Bernabéu turned sport into a crazy revenue machine, the Roman Empire had already understood the economic potential of gathering crowds and charging for access. At that time, amphitheaters were not only leisure spaces, but political and commercial tools where prestige and money mixed openly. In fact, businessmen like Atilio They saw the games as a direct opportunity for profit, betting on filling venues at all costs and maximizing every available seat. In that context, the logic of squeezing capacity (with privileged areas for the elites and crowded stands for the rest) not only existed, but was central part of the model. Raised to make quick money. In this context, it is born the Fidenae project with a clear idea: build a lot, quickly and cheaply to start earning money as soon as possible. Attilius, a freedman with entrepreneurial ambition, decided to build a huge wooden amphitheater on the outskirts of Rome, reducing costs in the most critical elements. The structure was supported on unstable ground and was assembled with poor joints, while more seats than planned were added to increase revenue. The result was a building that appeared grand from the outside, but was actually designed more to maximize profits. that to ensure safety of those who were going to occupy it. Spectacle turned into tragedy. What happened? That the inauguration attracted tens of thousands of people who came with the expectation of witnessing gladiatorial combats after a period in which these spectacles had been rather rare. That amphitheater was filled to the limitthere was no room for a pin, with the public distributed by social classes and areas, replicating a hierarchy that also had its economic reflection. Thus, in a matter of seconds, what seemed like a festive day he happened to enter sadly in the Guinness Book of a total sporting catastrophe when the structure began to give way and collapsed simultaneously inwards and outwards. It was not just an accident, since the magnitude of the collapse trapped both those who were inside and those who were trapped. were in the surroundingsleaving a balance of victims that, according to sources, ranged between tens of thousands of dead and injured. The worst sports disaster in history. From then until now, because of its scalethe collapse or collapse of Fidenae was not only a local tragedy, but the biggest sports disaster that has ever been documented, surpassing even many modern episodes in number of victims. The figures, although imprecise at the time, point to a catastrophe comparable to major battles in terms of human losses (they were counted about 50,000 deadsome lost their lives instantly, while others were buried under the rubble), something totally exceptional for an entertainment event. The speed of the collapse, the absence of evacuation measures and the fragility of the construction made any reaction impossible, turning the amphitheater into a mousetrap, a death trap in a matter of seconds. What should have been a profitable business ended up being the most extreme example of how the search for profit can multiply risk to catastrophic limits. From greed to the first rules. There is no doubt, the impact of that disaster shook the Roman Empire and forced an institutional reaction that marked a before and after in the construction regulation. The Senate persecuted the person responsible, Attilius, and sent him into exile, but, more importantly, established rules that They demanded economic solvency to those who wanted to organize shows and forced them to build on safe land. Those measures can be considered one of the first attempts to regulate structural safety in public spaces, born directly from a tragedy caused by negligence. Ultimately, the episode left a lesson that is still very valid: when business prevails over security, the show not only cannot be guaranteed, it can end up becoming in his own catastrophe.

The culprit: the air conditioning In Xataka | If you’re hot at home, remember that Disney made an auditorium with a huge mistake: turning a neighborhood into an unbearable oven

If you are going to install air conditioning, remember what happened to South Korea. It was the architectural disaster of the millennium

In the 1990s, some of Asia’s densest cities reached concentrate millions of people in urban areas built in just a few decades. In that same period, several studies began to warn that a significant part of the buildings erected during the great economic booms had serious structural deficiencies. In fact, in some inspections after major accidents, it was estimated that only a minority of buildings fully complied security standards. When you grow faster than you can build. In a few decades, South Korea went from the devastation of war to becoming an industrial and urban powerwith a speed of growth that was hardly unprecedented. Furthermore, during the economic boom in the 1980s, the country was chosen to host the 1988 Olympic Games, and an exorbitant number of buildings were built to meet these new needs. That impulse translated into a construction fever where building architectures mattered more than doing them well, and where practices such as cutting costs, accelerating deadlines or ignoring technical warnings became common. In that scenario was born Sampoong Department Storenot as a project exceptionally flawed from the beginning, but as a typical product of an era when progress was measured in square meters and not in safety standards. Air conditioning as a wick. The key point of the tragedy that was about to take place and that ended up turning the department store into the millennium architectural disasterit was not a single error, but a chain of decisions that ended up concentrating all the fragility of the building in an apparently secondary detail: the air conditioning system. As? Apparently, the equipment installed on the roof They weighed tens of tonsfar above what the structure could support, and their accelerated installation did not even follow normal procedures, as they were dragged on the roof, damaging the structure itself. From that moment on, a terrifying image: every vibration when you turn them on widened invisible cracks that toured the building. What should have been an element of comfort became a lethal burden that ended up acting as the final trigger for the collapse, concentrating years of accumulated negligence in a single point. The department store before the disaster Condemned from the plans. The disaster began long before anyone heard creaking in the ceiling. The original project It was a residential block four floors, but was transformed by Lee Joon, future director of the Sampoong Group, to turn it into a large shopping center without properly redesigning the structure. Plus: Due to bans in Seoul that prevented foreign companies from signing contracts in the city, these monstrous buildings were awarded to a handful of South Korean companies. Overwhelmed by pressure, companies decided that it was best to accelerate the pace of work, regardless of the cost. Thus, the diameter of the pillars was reduced from 80 to 60 centimetersand the distance between them was increased to increase the useful surface, columns removed to install escalators, its thickness was reduced to gain commercial space and a fifth floor was added that was never planned. Each modification increased the weight and weakened the resistancewhile companies that warned of the danger were fired and replaced by more accommodating ones. The result was a chaotic building that, on paper, no longer had a safety margin even before opening its doors. Cracks getting bigger. In the months before the collapse, the building gave multiple warnings that something was wrong. Visible cracks appeared, floors vibrated, employees felt dizzy, and engineers warned of a imminent structural failure. The management’s reaction was to close some areas, turn off the air conditioning at the last minute and continue operating normally in the rest of the building. The reason was so simple as devastating: Losing a day of sales in a complex that received thousands of people was unacceptable. Even on the day of the collapse, with cracks of several centimeters and obvious signs of danger, it was decided do not evacuate customers. Images after the collapse The collapse. On the afternoon of June 29, 1995, the building did not explode nor was it the victim of an external attack: he just gave in to the crazy number of negligence. The air conditioning equipment ended up passing through the weakened roof, the columns could not support the accumulated load and the building collapsed. collapsed in a matter of 20 secondscrushing entire plants on top of each other. More than 500 people died and more than a thousand were trapped, many of them in a space that, just a few hours before, symbolized the country’s economic success. It was a destruction so rapid that it turned a shopping center full of life into a mountain of rubble in less than half a minute. Images after the collapse An avoidable tragedy. Rescue efforts continued for weeks, with survivors found even more than two weeks later under the remains of the building. But the magnitude of the disaster revealed an even more disturbing reality: many victims did not die only from the collapse, but due to subsequent failures in emergency management. Meanwhile, investigations confirmed the most obvious: there was not a single cause, but one after another.accumulation of avoidable errorsfrom the use of low-quality materials to business decisions that prioritized immediate profit over any safety criteria. Monument in memory of the collapse Corruption, punishment and a system in question. The collapse not only destroyed a building, but exposed an entire system. Those responsible, starting with owner Lee Joon, were convicted, including several officials involved in corrupt practices, but the impact was much broader. Subsequent inspections revealed that a significant portion of Seoul’s buildings had very serious structural problemswhich forced us to review regulations and reinforce controls. The Sampoong ceased to be an isolated case and became in a symbol of what happens when a society builds too quickly and too badly. The legacy. Today, where the building stood there is no visible trace of the tragedy, but its lesson remains crystal clear. The disaster was not the result of bad luck … Read more

The largest naval project in German history since World War II is turning out to be a crazy disaster

by

In Europe, large military programs often take more than a decade to be completed and, in many cases, end up costing several times more than initially anticipated. It is not uncommon for complex projects to accumulate thousands of technical requirements and go through multiple reviews before reaching production. In this context, some plans are born as emblems of modernization… and end up becoming examples of how difficult it is to bring them to fruition. From something historic to something unsustainable. He program F126 was born as the great symbol of German rearmament and largest naval project of the country since the Second World War, but over time it has become quite the opposite: an example of how an ambitious plan can derail to the point of collapse. Conceived as a latest generation frigateflexible and prepared for decades of service, the project has not only accumulated delays and cost overrunsbut has called into question Germany’s ability to execute large military programs at a time when it aspires to lead European defense. Technical errors and chaos. He told in an extensive report the financial times that the origin of the problem seems as modern as it is devastating: a failed bet on a new software design that was not ready for a project of this scale. What should have been an advanced tool ended up generating cascading errors, from cables incorrectly located on the plans to steel parts manufactured with incorrect shapes, forcing manual corrections and slowing down the entire production. The result was a system that was moving at just a fraction of its planned pace, with delays that pushed the initial delivery several years later than planned. A culture shock. It turns out that the problem was not just technical. Apparently, the media reported that the project was trapped in a deep shock between the Dutch shipyard’s way of working and the German contracting system, known for its extreme rigidity. Thousands of specifications detailed even the smallest elements, while approval processes were they dragged on for months within a complex bureaucracy that required paper documentation and rejected even plans in English. This combination made collaboration a slow, frustrating, and, in many cases, unproductive process. Skyrocketing costs and limit decisions. As the problems piled up, so did made the invoice: The project, initially valued in the billions, began to go off track with significant cost overruns and structural delays. As it is, Germany now faces critical decisions ranging from replacing the main contractor to accepting billions already invested. as irrecoverable losses. At the same time, faster but less ambitious alternative solutions are being studied, reflecting the extent to which the original project has lost credibility. Notice to sailors of rearmament. If you like, the case of the F126 goes beyond a simple industrial failure: it reveals the limits of European military cooperation even among closely integrated countries and raises questions about the continent’s ability to implement complex joint programs. In a context of increasing of defense spending and increasing strategic pressure, the project has become a clear warning: It is not enough to invest more, you also have to know how to manage better. Because otherwise, even the most important projects can end up being, as in this case, a costly and lengthy example of what not to do.

Japan sent the wrong creature to eradicate snakes from an island. The disaster was so big that it took half a century to solve it

by

Once again, desperate situations lead to extreme measures. Save a species sometimes it involves “exterminating” another. We have seen it in South Africa and his plan to annihilate miceeither injecting radioactive material into the horns of rhinosthe cases of hunt the wild cator the plan for exterminate half a million owls. However, sometimes things do not go as governments imagine. In Japan they know it perfectly. The incident of ’79. The story begins in 1979 on the Japanese island of Amami Ōshima, located in the Kagoshima prefecture. That year, Amami’s rabbit is rediscovered (Pentalagus furnessi), an endemic species and considered a “living fossil” due to its evolutionary antiquity. Before the discovery, the rabbit was thought to be on the brink of extinction due to habitat loss and hunting. The discovery marked a before and after for the conservation of the species and highlighted the importance of protecting the natural environment of the island, home to many other unique species. An event that also highlighted the need for greater conservation efforts at Amami Ōshima, for example trying to eradicate or control the snake population. A wrong “bomb”. Thus, a few months later, Japan launched a plan. Introduces around 30 mongooses to the island with the intention of ending the population of snakes, specifically the habu (Trimeresurus flavoviridis), which represented a threat to the local inhabitants. The idea, on paper, was a seamless plan: that the mongooses, which are natural predators of snakes, would reduce the number of habus and improve security on the island at all levels. However, that project was far from infallible. The mongoose was not the ideal creature to eradicate snakes. Firstly, because they are animals active during the day, therefore, they could not catch the nocturnal habu snakes, which continued to inhabit the following decades without problem. What happened as a result had an enormous ecological impact. A specimen of Trimeresurus flavoviridis Predation of endemic species. Thus, during the day, instead of focusing on the habu snakes, the mongooses began to prey on a wide range of native species, including several that had no natural enemies on the island until then. That seriously affected the local fauna, especially endemic and endangered species, like the same Amami rabbit that had just been happily announced months ago. Hundreds of thousands of mongooses. The situation reached such a point that the mongooses, brought in to eradicate one pest, had become an even larger and more dangerous one, one that It reached around 10,000 copies. at its peak around the year 2000. The truth is that Japan had already started a mongoose control project in 1993 that was expanded over time. As? Around 30,000 traps were set on the island to capture the animals and cameras with sensors were installed to monitor them. In addition, local residents formed the so-called Amami Mongoose Bustersa team specialized in capturing mongooses (they captured thousands). The end? In 2018, the last official capture of a mongoose on the island occurred. It occurred in the month of April, and since no creature has been captured for a long period of time, the expert panel, which is tasked with determining whether the animal is eradicated from the island, estimated that the eradication rate was between 98.8 and 99.8% in February last year, reaching a preliminary conclusion that it is reasonable to say/think that mongooses are eradicated from the island under the current circumstances. Finally, on September 3, 2024, Japan’s Ministry of Environment declared eradication of non-native mongooses on the island of Amami-Oshima, declared a World Natural Heritage Site by UNESCO. The statement was based on the opinion of the expert group on scientific grounds, taking into account that the capture of mongooses has not been confirmed for more than six years since the last one in April 2018. A unique case. The ministry itself did not hide the disaster that was the attempt to control the snakes in 1979. In fact, and as the administration has announced, it is one of the largest cases in the world in which non-native mongooses that had been established for so long have been eradicated. After the statement, the government explained that it will remove the traps that were placed on the island, although it will continue to monitor with cameras to prevent a new group of these small creatures from entering again. After all, if it took half a century to get them out of there, any contingency method is more than understandable.

The Bernabéu was facing a financial disaster after the concert fiasco. So he has converted to tennis

by

The Bernabéu will convert its retractable grass into clay courts for training at the Mutua Madrid Open 2026. The move is possible thanks to the engineering of the stadium renovation, which has invested more than 1.3 billion euros, and the gap in events left by Real Madrid’s calendar. It is also the latest expression of an ambition that has been colliding with neighbors and noise limits for years. What’s going to happen? From April 23 to 30, the Santiago Bernabéu will stop being a soccer field and become several clay courts. The best tennis players on the circuit (among others, Carlos Alcaraz, Jannik Sinner, Aryna Sabalenka and Iga Swiatek) will train at the Real Madrid stadium during the first week of competition of the Mutua Madrid Open 2026, which begins on April 20 at the Caja Mágica. The Bernabéu will be a minute’s drive from the players’ hotel. The information, advanced by The New York Timesmarks the arrival at the stadium of a sport that Florentino Pérez has been fooling around with for years. How to do it. All this is possible thanks to retractable pitch system installed during the remodeling of the stadium, completed at the end of 2023. The field is divided into six trays measuring 107 by 11.67 meters, each weighing approximately 1,500 tons, which are moved by 24 transport carts and stored in the hypogeum: a 30-meter-deep underground greenhouse equipped with growth lamps and air conditioning systems that keep the grass in optimal condition. The entire process takes approximately six hours. Once the grass is stored, the concrete base is free to install any other surface, such as clay for tennis. It is the same mechanism that allowed us to host the first NFL game in Spain last November. 1.1 billion does not pay for itself. The conversion into a multifunctional stadium is not Florentino’s whim, although he tries to sell us that it has always been a personal dream, as we explain below. The renovation of the Bernabéu has cost, after chaining up to three loans, around 1,100 million euros. Football is not enough. Real Madrid plays around twenty home games per season, which leaves the stadium empty more than three hundred days a year. The strategy is to fill those days with events that generate additional income, following the model already practiced by facilities such as SoFi Stadium in Los Angeles or Tottenham Hotspur Stadium in London. The club surpassed €1.2 billion in annual revenue in 2023-24 in part thanks to this diversification. AND as we counted at the timethe large Spanish stadiums are looking for new sources of income: Athletic is studying options with San Mamés, Betis is working on Villamarín, Barcelona has just invested 1,450 million in the Camp Nou. They all look for the same thing: that the business does not depend on those 19 or 20 game nights a year. Dreaming since 2019. In the general assembly of Real Madrid that yearthe club president explained that injuries had frustrated several attempts to organize an exhibition match between Rafael Nadal and Roger Federer at the Bernabéu. Pérez had been thinking about the idea for some time. Federer retired in 2022, Nadal in 2024, and the match never came. But the link with tennis remains intact: Nadal has declared on several occasions his desire to preside over the club one dayand Alcaraz, number one in the world, is a declared Madrid fan. The first team players frequently appear in the boxes of the Caja Mágica during the tournament. That the Bernabéu now hosts the training of the circuit’s great figures is, at least, the modest and executable version of that effort by Florentino Pérez that was never fulfilled. Previous setbacksand how to solve them. The plan to turn the Bernabéu into an events machine has had a serious setback: the concerts. Since the inauguration of the stadium as a music venue in April 2024, the residents of Chamartín complaints about noise levels accumulated which sometimes exceeded 85 decibels, when the municipal ordinance establishes a maximum of 53. The City Council processed sanctions for a total of 2.6 million euros between April and December 2024. In September 2024, Real Madrid suspended the concerts scheduled until early 2025, and the complaint by the Association of People Injured by the Bernabéu is still ongoing. The situation ended up expelling artists like AitanaLola Índigo or Dellafuente from the stadium. On the other hand, tennis training does not generate this problem: a group of tennis players training in a stadium without 80,000 attendees in the surrounding streets is, acoustically, an activity of another category. For the club, it is also a way to demonstrate that diversification is possible without raising eyebrows. In Xataka | Shakira is not convinced by any stadium in Madrid to close her world tour.

Throwing concrete into the sea is usually a disaster or cause for conflict. The United Kingdom is using it to revive an ecosystem

by

When huge blocks of concrete are thrown to the bottom of the sea, we can think that whoever is doing it is looking for a territorial conflict or even to ruin the ecosystem, as It was already seen in Gibraltar in 2013 in order to prevent fishing. However, on the coast of the United Kingdom, this same action of throw concrete blocks It has become the spearhead of one of the most ambitious bioengineering and ecological restoration projects in Europe, despite being contradictory. The objective. The objective of throwing these blocks is to bring reefs back to life of native North Sea oysters, lost more than a century ago due to overfishing, pollution and the destruction of their habitat. Heavy engineering. At first glance, it seems simple to take some concrete blocks and throw them over the side of a boat. But in reality the 20 blocks recently deployed off the coast of Tyne and Wear are actually pieces of green high-tech. And it’s no wonder, because have been developed ARC Marine under the name Reef Cubes and made with a special material called “Marine Crete”. Furthermore, they are not small at all, because each of these cubes weighs six tons and measures one and a half meters high. Why this weight? This initiative promoted by the Zoological Society of London (ZSL), the Wild Oysters project and Groundwork, leaves nothing to chance, since the fact of launching these heavy masses of concrete is explained by the British climate. In the previous phases of this project, the team encountered devastating storms that destroyed all restoration attempts. That is why these six-tonne masses ensure that the violent ocean currents and waves of the North Sea do not move the structures even one centimeter so that they can develop their final objective. Its usefulness. The magic actually happens on the surface of the block, as these cubes are not entirely smooth, but are designed with complex rough textures and artificial pores that perfectly mimic natural marine surfaces. These automatically become the perfect anchorage for life to thrive and an ideal refuge for fish and crustaceans. The role of oysters In addition to the roughness, 4,000 native European oysters have been placed inside each of these 20 immense cubes thanks to the efforts of 190 local volunteers. And it makes all the sense in the world, because beyond their great gastronomic value, oysters They are the great “purifiers” of the ocean. To give us an idea, a single adult oyster is capable of filtering up to 200 liters of water per day. In this way, when they feed they eliminate pollutants, nitrogen and excess nutrients, radically improving the quality of coastal water and allowing sunlight to penetrate deeper, which in turn stimulates the growth of marine flora. In short, these blocks act as a new ‘home’ for the animals that live on the seabed, but also as a way to clean their environment. It already gave results. The robustness of using thousands of tonnes of concrete on the seabed has already been tested in Scotland with great success, and now this project is just the beginning of what is to come. That is why, while these artificial reefs begin to filter millions of liters of water daily in the north, other projects are taking note to scale the idea to titanic proportions. In Norfolk, initiatives such as Oyster Heaven and Norfolk Seaweed are already planning the deployment of 40,000 clay “Mother Reefs” by the end of 2026. Their goal is to house 4 million juvenile oysters, which would officially be crowned the largest restored reef in all of Europe. In this way, throwing blocks into the sea has gone from being a technique to create conflicts between regions to being able to recover part of an ecosystem.
