In 1970, a zoologist released a species of rodent into the Caucasus to repopulate it. A century later the destruction is gigantic

by

In the 1970s a story occurred, one of many, where the man tried to modify the ecosystem of an island and it went completely wrong, so much so that It took them half a century to solve it.. However, among the stories with the sending of a “solution” to an enclave as the protagonist, good to annihilate, good for repopulatingfew like the one that occurred 70 years ago in an area of ​​the Caucasus. Unlike the story from Japan, here there is still no way to solve it. Introduction: Soviet ecological ambition. About the 1920s, the Soviet zoologist Nikolai Vereshchagin undertook an ambitious project to “reanimate” and repopulate the fauna of the Caucasus. The idea seemed simple: introduce non-native species. Inspired by the desire to restore ecosystems and provide economic benefits through hunting and the fur trade, Vereshchagin brought animals from different parts of the worldconfident that they would thrive in the mountains and wetlands of Azerbaijan. Apparently, through his investigations and his book “The Mammals of the Caucasus”Vereshchagin documented the constant change in the region and argued in favor of what would become known as “acclimatization”: a species adaptation strategy that sought to enrich local biodiversity, even if over time it proved to have… let’s say, unintended effects. The coypu: from Soviet experiment to invader. And of all Vereshchagin’s most notable experiments, one is written in capital letters with the introduction of the coypualso known as otter or river rat, a species of giant rodent native to South America. Were 213 copies brought to the region, which quickly adapted and thrived in the wetlands of Azerbaijan. Because? Originally, the coypus They were brought for the quality of their skins, used in the making of luxury coats and hats. However, what began as a resource exploitation project soon became an ecological problem. The reason? Coypus demonstrated a high reproductive capacity and adaptability that allowed them to survive and multiply as if there were no tomorrow without the natural predators of their original habitat. This rat is a danger. To give us an idea, currently the coypu is considered one of the 100 most dangerous invasive species worldwide. In Azerbaijan, their populations are ubiquitous in wetlands, causing significant environmental damage by destroying native vegetation and competing with native species for space and resources. Additionally, their presence threatens the habitats of endangered birds, such as the cotton-headed duck and Siberian crane, as both depend on these wetlands for their survival. We are talking about a species whose adults measure approximately 60 cm long and have a 30 cm tail. When fully grown, they weigh as much or more than a Jack Russell terrier. Although they look similar to the capybara (the largest rodent in the world), coypu tend to have fewer “followers.” One fact gives an idea: its most notable feature is its protruding teeth, a pair of long, orange incisors that they never stop growing. Impact on biodiversity. The ecological impact of coypu in Azerbaijan was tremendous over the years, and especially significant due to the natural wealth of the Caucasusa region considered as one of the 25 hotspots of global biodiversity. The creature not only devastated the vegetation in humid areas, but its destructive behavior also affected bird nesting areas. In fact, studies carried out in Italy show that these giant rodents can reach crush nests by resting on themincreasing the risk for local species. Not only that. The species continued to spread to this day, and from the Caucasus it passed to neighboring countries, which has made its management even more complicated. The lack of a detailed study on the size and distribution of their populations in Azerbaijan poses all kinds of additional obstacles for environmentalists, who do not have a solid basis for developing mitigation strategies. Management and reward programs. Today, and in response to the uncontrolled expansion of the species, some experts suggest implementing reward programs for capture, an idea similar to those that have been effective in enclaves of the United States such as Louisiana, where it is offered a payment for each coypu queue delivered. However, others warn that these programs, while temporarily reducing populations, can result in commercial hunts that do not completely eradicate the species. In this regard, the proposal to reestablish a reward system, in force in Soviet times, is viewed favorably by organizations such as WWF Azerbaijan. However, the current system of fees and penalties in the country, which even requires hunters to pay additional payments for “environmental damage,” discourages coypus hunting. Therefore, there is a clear contrast with other countries where the reduction of invasive populations is actively encouraged. Lessons learned and future. Like so many other similar stories with the “hand” of man throughthe story of coypu in Azerbaijan is a reminder of the risks of introducing foreign species without very careful planning and long-term impact assessment. Although no one doubts that the projects of Vereshchagin and his contemporaries were based on good intentions, the collateral effects of their decisions have been tremendous for the region’s biodiversity. Today, environmentalists like Zulfu Farajli told the BBC who advocate for greater public awareness of the impact of coypus on local ecosystems, as well as more effective management policies. Ultimately, the case of this creature in Azerbaijan highlights the importance of developing a conservation approach based on science and sustainability, ensuring that ecosystems can recover and thrive without the threat of invasive species. Hopefully, the solution will never be a giant rat, please. Image | Peter Trimming, Khagani Hasanov1988 In Xataka | Japan sent the wrong creature to eradicate snakes from an island.

The best horror movie of this winter has been released. And the protagonists are the owners of a home in Spain

by

The abrupt rise of the garbage rate that has exploded throughout Spain is not the result of a improvised decision of each town hall, but rather of the rush to have arrived at the last minute. Namely: of the obligatory application of Law 7/2022 (transposition of European directives) which orders that the waste service should no longer be partially financed by general taxes and be paid 100% by a specific rate based on the “polluter pays” principle, eliminating the structural deficit that many municipalities had been carrying. What has happened? That the “garbage” is more noticeable in some places than others. The normative origin. The norm established a maximum period until April to incorporate it into ordinances, which has meant that municipalities that delayed its application have communicated the charge practically at once, with increases that in some cases double or triple previous receipts and are already reflected in the CPI with an increase 30% year-on-year in the cost of the service, despite the fact that not all municipalities have implemented it yet, which anticipates additional increases when the deployment is full. In other words, curves are coming. Cangas de Morrazo as epicenter. As it is, the first public implosion has happened in Cangasin Pontevedra, where neighborhood anger became an episode of public order with councilors escorted by the Civil Guard and throwing objects after approving an ordinance that in bars went from 107 to 1,236 euros and in homes it practically doubled receipts, accumulating more than 8,000 signatures against an increase perceived as abrupt, without a transitional phase or prior dialogue. Hoteliers allege unviability when passing bills from 1,400 to more than 3,000 euroswhile regretting that the process was carried out without calling affected actors before approval, which has turned a legal requirement into a political trigger, in a framework where the service had 17 years without updating rates and was deficient in more than two million per year, compensated via general taxes that can no longer be used for this purpose. The inequalities. The law requires a rate, but does not dictate how to calculate itwhich has generated a mosaic of municipal models with disparate criteria: cadastral value, water consumption, number of registereduse of the premises, area or even flat rate per home. This diversity implies that citizens of adjacent municipalities pay very different amounts for an equivalent service, something already warned by the FEMP and by Treasury inspectors as a sure source of massive litigation. The recent annulment by the TSJ of Castilla y León, an ordinance from León opens a path that businesses, schools and sectors especially hit with receipts are already exploring up to 30,000 euros. Experts warn that the reference to the cadastral value may constitute a vice of illegality by disconnecting from the actual generation of waste and functioning de facto as an improper surcharge of the IBIwhich could reproduce a similar scenario to the municipal capital gains: imposed instrument, politically supported, challenged in a cascade and finally revoked, with an obligation to return it to whoever has resorted to it within the deadline. Europe: obligation and margin. Political tension is fueled by a deliberate misunderstanding: Brussels demands compliance with recycling, reuse and circular economy goals, but it does not force that the instrument is a rate nor does it mark the calculation formula. In fact, it was the Spanish legislator who chose this path and transferred the technical and political responsibility for executing it to the city councils, without defining a uniform standard cost methodology or setting national equity criteria. The result is a double cross reproach: The city councils accuse the Government of imposing an obligation without an application manual and the Government points to Europe to cover a decision of internal design with inevitability, while the citizen perceives that they are beginning to pay directly for a service that already existed and whose cost structure is not explained precisely, which erodes the social acceptance of the tax. Economic effect. The rate not only makes household and business bills more expensive, but reorder incentives: If the deficit can no longer be covered by taxes and must appear on the invoice, the system penalizes waste volumetrics and rewards separation and reduction practices where ordinances have introduced bonuses linked to the use of brown containers, composting, door-to-door or clean points. However, and very importantly, in large cities many current models do not reward individual behavior, proxy rules apply (cadastral, surface, neighborhood) and generate equal payment for neighbors with radically different behaviors, something criticized from environmentalism for diluting the environmental purpose of the norm. Meanwhile, the jump 30% in CPI and business cases with receipts multiplied by three have produced not only social irritation but fear of a massive wave of resources, in a context in which city councils acknowledge that they are already preparing legal defense anticipating that the rate could become a new fiscal front with a path to court. Conclusion: a sinvivir. The crisis of the “garbage” It is not born in the amount but in the combination of inexcusable legal obligation, abrupt transfer to the taxpayer without cushioning, disparate heterogeneity between municipalities, poor communication, absence of national guidance and a highly fragile legal system that opens the door to serial litigation. Cangas has been the first burst visible of a phenomenon that is structural: Spain has made it a norm to finance waste with taxes pass them on in full as a rateand this simultaneous redesign without homogeneity or pedagogy has coincided with inflationary cycles, accumulated business burdens and distrust of administrations, producing a perfect storm that mixes environmental compliance, fiscal shock and perceived legitimacy.

Spain wants us to buy electric cars that are manufactured here. And it has just released another 400 million euros for it

by

2035. That is the date that Europe has marked on the calendar as the end of the sale of new gasoline and diesel vehicles. Despite the voices against it, the EU believes that removing the combustion cars and reduce emissions of those sold until then is the way to get the decarbonization goals. Spain has to join this initiative and, to do so, it has just added 400 million euros more to the PERTE VEC project. Because the future of mobility seems to be electric… or it won’t be. PERTE VEC. The Strategic Project for the Recovery and Economic Transformation of the Electric and Connected Vehicle, or PERTE VECit is a initiative which was approved in July 2021 with the aim of creating a favorable Spanish ecosystem for the development and manufacturing of electric vehicles. It is a program that foresees a total investment of more than 24,000 million euros with a public contribution of more than 4,000 million and, the rest, private investment. And the objective is that: to help companies see Spain as an interesting ecosystem to carry out the vehicle development and manufacturing process. This includes production, but also innovation and research in components, batteries and other technologies associated with the electric vehicle. 400 million more. With this objective of facilitating the green transition of the automobile fleet, the Ministry of Industry and Tourism just launched the fourth call of the PERTE VEC. In total, 400 million euros more to give value to this production chain, which are divided into: 250 million euros as repayable loans to a fixed interest of 2.8% and a term of 10 years. 150 million euros in direct subsidies. New call. Companies that wish to do so have from October 14, 2025 to October 24 to register. These 400 million are a fraction of the total of PERTE VEC IV, which has a budget of 1,250 million euros that will be released in successive phases. And no, it is not a program like the MOVES III, which directly concerns the consumer: the PERTE VEC is focused on companies. A limitation is that they cannot be public sector companies and must have demonstrated capacity to carry out their projects. Complying with this, the beneficiaries can be all those companies with their own legal personality in our country that carry out activities related to the development of electric vehicles. This implies that they do not have to be the big brands, but also companies that manufacture batteries, electrical components, charging systems or even those that develop software. Chinese brands included. As long as they meet the requirements, Chinese companies can also benefit from this. The Asian giant saw before many others the importance of the transition to electric as a way to support the achievement of decarbonization objectives and, in fact, this European ambition is something that we have been witnesses for months. The objective of measures like this is, precisely, that value chains are established in our territory and that companies are not limited to bring your cars on big ships from china either simply to assemble them in Europebut to make them here. And an example that Chinese companies are welcome was the formal invitation from the Ministry of Industry to the Chery company to present its application to the PERTE VEC.

Seoul has released a “holographic police” that arises every night in a park. The intention is clear: dissuade crimes

by

A park in Seoul transforms every night into an unexpected stage. From seven in the afternoon, between street lamps and shadows, the figure of a police with impeccable uniform arises. Speak in a firm voice, throw a message and, suddenly, fades in the air. Two minutes later, it reappears to repeat the same scene. It is not a flesh and bone agent, but about Un real size hologram which has become the new attraction and security measure of the neighborhood. The bet began in October 2024 as an experiment of the Jungbu police station and the Seoul City Council. The selected park was not accidental: located next to the popular gastronomic area of ​​Euljiro, it was the usual scenario of incidents linked to alcohol consumption, As the local newspaper The Scoop explains. Police were looking for a way to strengthen security without displaying more personnel in difficult coverage. Thus collaboration with a technology company arose, which designed a system capable of projecting a virtual agent every night to remember that the place was monitored. A HOLOGRAM AGAINST CRIME The device uses a projector that launches the image of a policeman on a real -size acrylic plate. Every night, the hologram appears for a few seconds and repeats again every two minutes. Its presence is not limited to the visual, since in a clear voice it always conveys the same notice, which Remember passersby permanent surveillance of the area: “Hello, we are the Jungbu police station in Seoul. This area has an intelligent CCTV system. This system is in operation so that the police can respond in real time if an incident of violence or other emergency situation occurs. The Jungbu police station will continue working with the district to create a safer community. Thank you.” The first data collected shows that the bet has not gone unnoticed. According to figures from the Jungbu police station, between October 2024 and May 2025, incidents registered in the Park were reduced around 22% compared to the same period of the previous year. The descent was noticed above all in situations of spontaneous origin, such as altercations or discussions linked to alcohol consumption. For the police, this initial effect demonstrates that the hologram has served to cover holes in the usual surveillance. Those responsible for the project insist that the idea was born from a very specific need. Agent Kim Hyun-Don, from the Jungbu police station, He explained in an interview with the South Klab Canal that the park was surrounded by bars and leisure premises and that many neighbors preferred to avoid it at night for fear of meeting drunken people. “We thought that a visible policeman, even if it was virtual, could give security to citizens and at the same time deter those who could cause problems,” he said. For the police, the hologram is a risky experiment, but also an opportunity to innovate in prevention. Not all citizens interpret the hologram in the same way. While some perceive it as a presence that provides security, others believe that the measure will lose efficacy over time. A neighbor interviewed by The Scoop warned that “to really reduce incidents Frequent patrols are needed or a change in the dynamics of the neighborhood. ”In parallel, comments on the Internet oscillated between the joke and surprise: several users described it as a“ police ghost ”, although others celebrated the originality of the experiment. Seoul Metropolitan Police The project, despite its good initial results, is not free of problems. Those responsible admit that technology is sensitive to external factors: on extreme heat or intense cold days, The projector can fail. There are also neighbors who complain that the voice of the hologram is not heard well when there is noise in the street. To this is added a deeper doubt: if at the beginning it impresses and deter, over time it could become part of the landscape and lose its impact. Seoul’s “holographic police” has become a striking experiment within the debate on how to strengthen security in public spaces. Its initial efficacy shows that technology can provide creative solutions, although doubts about their permanence remain open. It remains to be seen if this model will consolidate as a stable tool or if it will remain an anecdote in the urban history of the city.

Vigo Airport has released a digital tower “at the forefront of efficiency.” Has lasted four days

by

Announced as “the avant -garde of efficiency and safety in the air sector”, Vigo airport has begun working with “the first digital tower of Spain.” Four days later, the work has stopped for a first problem. And, in the background, the doubts about its real effectiveness, the position of workers and the shadow of some layoffs. Vigo, now with Digital Tower. It was announced by Oscar Puente, Minister of Transportation, with the words we collected above. In a tweeton June 17, the politician pointed out that Vigo received a strong change in his way of working. The project started with a Vigo-Madrid flight and was qualified by bridge as “a technological milestone” that places the facilities of Vigo “at the forefront.” Four days later, the entire system has had to stop by a Error caused at 31 minutes to go into operation. What is a digital tower? A Digital Tower For air control, it comes to replace traditional control towers. In the latter, controllers work at great height to control by computer systems and their own view air traffic. In this way, it is always about choosing the best option to manage the entry and exit of flights into the maximum safety conditions. A digital tower uses all these computer systems but changes the “windows” of the screens control tower in which what the cameras see are recorded. In addition, it has a multitude of sensors and microphones to simulate with maximum precision the same sensations as an air controller has in a traditional tower. Is it better? According to the words of the Minister of Transportation, yes. AND According to Aenaalso. They ensure that the videoWall that forms 13 55 -inch monitors represent a 360º image of what is seen in the tower. This allows them to have visibility of areas that are covered in the traditional tower. The installation, as we say, has fixed cameras and two mobiles. As well as “speakers that reproduce the ambient sound of the microphones installed in the flight field.” In addition, AENA points out that “they provide a series of operational and security advantages” although it does not give examples of them. And emphasize, because it is important, “maintaining the same number of controllers.” War foot. That last part of the message is important. In social networks, numerous accounts that expose the feeling of aerial controllers have been radically opposed to the implementation of these “digital towers.” The well -known account @Controlerators in x He qualifies the digital tower of “basement with cameras designed to control several airports”. And that is the great reset that has raised among the workers. In the environment, the feeling that operations of the Airport of A Coruña can be replaced with the air management of the Viguesa Digital Tower. Alvedro (A Coruña) and Peinador (Vigo) share a company managing air control services (Saerco) so A reduction in the number of workers is feared For a remote control of both airports. In The voice of Galicia They even point out that AENA neither confirms or denies that A Coruña workers can be replaced by the new digital control tower. BNG and the Popular Party They are already working to paralyze the project. “Quite obvious defects”. In addition to the works that may be in the air, the Union of Air Controllers (USCA) ensures that Aena has rejected its request for include “high definition cameras” And they emphasize that the system does not improve the traditional because “They are not clearly appreciated Small aircraft. “They are, in the words of the” quite evident defects “union. They emphasize in words to Vigo lighthouse that the system presents operability restrictions in specific weather situations and that “would entail the imposition of time restrictions that would prevent the simultaneity of visual flights (VFR) and instrumental (IFR).” That is, for the union, a problem for “urgent health transport, customs surveillance, fire extinguishing services or maritime rescue, as well as schools or private flights.” Many doubts. Although Aena points out that “currently, more than 30 European airports have implanted that technology and is operating from a digital control tower. Outside Europe, initiatives are being developed in Australia, Canada and the United States airports,” the truth is that the operation of these digital towers raises doubts. In fact, tests in Spain are being carried out for years. In 2023 problems were already reported In the Vigo airport digital tower related to the imprecise detection of small aircraft. The project was approved in 2019, it was awarded in 2020 and until this year it has not been launched with the first flights. Something similar has happened in Menorca, where it is also being tested with a digital tower that At the end of 2022 he also reported problems security This air control system It should be underway in 2021 But for now he has not exceeded the evidence and has ended up being Vigo the city that has been awarded the first “digital control” of a flight in Spain. Joy, yes, has lasted four days. Photo | Enrique Dans and Aena In Xataka | We have been waiting for years at airports for years. Tiktok’s “airport theory” believes that it has been a mistake

New York has released its new and revolutionaries garbage containers. They have been in Spain for decades

by

They call it “The garbage revolution”although it really has little revolutionary. At least for any European accustomed to doing something as simple as throwing their waste into the garbage can. On Monday the New York authorities They took chest announcing its new and brand new strategy to manage the waste of the Big Apple, a pilot program that is now bounded to a neighborhood and,, according to their driversit will be a pioneer throughout the United States. So far not surprising beyond political rhetoric. The funny thing is what New York wants to boost that peculiar “revolution” of cleaning: with garbage cubes and trucks such as those seen in the streets of Spain for decades. Garbage. In New York, workers of the garbage collection service are forced to do something less and less frequent in Spain and most European cities: withdraw on the sidewalks plastic bags full of waste and throw them to the rear of a truck. For them it is a Latoso work. For the city, a problem: the bags are piled up in the streets, hinder the passage, generate bad odors, overthrow liquid and attract rats. In fact, the New York town hall has already had to see them with Rodents. That is why in countries like Spain a different strategy has been chosen for a long time. Collectors are installed in the streets so that citizens can throw their garbage bags inside, leaving them safe from rats and seagulls. Over the years the system has been purified with wild boar cubes, collectors endowed with Electronic locks that are unlocked with special cards and systems that facilitate the discharge of garbage inside the trucks. Revolution in New York. After half a century Of “accumulation of garbage in streets”, in New York they have decided to say enough and change their garbage collection model for a new one, very similar to that of Europe. The first step was taken in 2023, when the authorities demanded from the businesses of the food branch (from bars to supermarkets) that they deposit their waste in containers. A year ago that obligation extended to all companies and in recent months the same standard has been making its way between small residential buildings. The great change has now arrived with a pilot test in the streets of the Community Board 9 of Manhattan, where the use of containers will apply to all types of residential buildings, from small blocks of less than ten homes to the largest, with more than 30. The City Council claims that the neighborhood has thus become “the first neighborhood of North America to have 100% of its garbage in containers” and even speaks of a “garbage revolution.” An old flavor revolution. The most curious thing is that this revolution really has little revolutionary. At least from the perspective of Europeans, who have been (if not decades) accustomed to the tools with which New York now wants to improve the management of their garbage. The reason is simple: the change in the Harlem will basically be supported on three pieces, all integrated for a long time in the urban landscape of the Spanish cities: Empire garbage cubes with capacity for 3,000 L, collectors with wheels and side load trucks. Closed and card cubes. Over the last weeks the New York Health Department has dedicated itself to installing in West Harlem around 1,100 Empire containerswhich are the ones that present a small novelty. Unlike most garbage cubes that can be seen in Europe, these collectors will not be available to any neighbor who passes through the sidewalk. They will remain closed and their use will be assigned exclusively to a building, which can access the collector thanks to a special card. In fact, residents will not even pull the bags in the cube. The idea It is that they leave them in an area of ​​collection in the building itself and the cubes themselves handle them the staff of the buildings or the waste managers. It is not the model that is usually used in Spain, although here They also look card collectors. Measuring buildings. The largest blocks of West Harlem, those with more than 30 homes, have been assigned Great Empire Garbage Cubes. Those between 30 and 10 apartments are allowed to choose between that smaller model or containers with wheels and the buildings with less than a dozen families are asked to use 200 l cubes. To expedite the work of the operators, a year ago the City Council also presented a prototype of garbage collection truck with lateral load that can be handled by only two operators. In November the Consistory has already asked these smaller buildings for residential use to start using containers, which has a first idea of ​​what is their result. Your conclusions? “The first data show that the use of containers is working: since the demands entered into force, six months ago, the number of rats has decreased,” celebrate. A revolution with challenges. New York is discovering more than the use of containers. He has also encountered the challenges they represent. The New York Times public A chronicle This same Monday explaining how cleaning service employees have to deal with double -row cars that block the cubes and prevent trucks from accessing them. It also warns of the impact they will have on the parking spaces. The municipal authorities already calculate that expanding the program to the entire city would demand to eliminate 50,000 spaces to park vehicles. That without having the hundreds of millions of dollars that would require buying garbage cubes and collection trucks capable of attending the entire population of the Big Apple. Critics write down a “but” more: That the initiative to recycling does not expand. Image | City of New York In Xataka | The cities emptied during the pandemic.

Why many have felt more released than ever during the great blackout

by

In Madrid, during the longest hours of the blackout, Andrés had a “rare” sensation similar to that of the pandemic, as of the world arrested, of much slower time, of silence. In Malaga and without radio at home, Matías thought it was something local and began to water the plants. They were two hours of absolute inner peace. In Ciudad Real, if data or portable, Alex sat with his dog to enjoy the breeze that entered the window. And it was not the outside world. It could not be: in the houses there was the same usual noise, the streets were more full than normal, the universe continued to turn. What was happening? Peace in a world in ruins. Because that is the first thing that comes to mind: the paradox that in seemingly negative (or even tragic) situations such as blackouts, The pandemics Or external events of this type, people experience a rare sensation of peace, liberation or decompression. However, psychologists, sociologists and anthropologists make it clear that the paradox is only apparent. Actually, we are so accustomed to living in lives full of labor commitments, studies, social activities; lives immersed in a constant information flow … that such an event disrupts us deeply. Or, rather, it destabilizes us: as experts in behavioral activation therapies tell us, our day’s activities are as emotional anchors. Without them, we are much more susceptible to external incidents; whether positive or negative. The surprise, of course, is that they are sometimes positive. We could study it with great detail during the pandemic. For example, a group of researchers from the University of Cambridge They discovered that one in three young people had felt happier during the confinements. But he did not reduce them: it’s something, in fact, We find surprising frequency. But … why? It has theorized a lot about why (less social and academic stress: less loneliness, absence of bullying, more hours of sleep or more physical exercise during confinement …), but they all end up in the same place. To the elimination of the aversive elements of everyday life and the increase in pleasant activities, something else adds: the absence of responsibility. That is the key piece that allows to accept inactivity with less resistance. It is not free that among the health, for example, this type of phenomena were less frequent during pandemic (even when they were sick). The feeling of guilt or responsibility did not disappear and, in fact, it became a problem. What leads us to a question … What if the problematic is normal? In 1922, Dorothy Thomas realized a very curious detail: Unlike what we might think, mortality seemed to follow a “procyclical” pattern. That is, as the economy goes better, more people die. It is so. It is something we have seen one and again: The last great Spanish crisis is a good example. The evidence is solid: economic growth has as a direct consequence that people die more. As explained in the Silesia collective“There is something in the political-economic system of capital circulation and goods that, when accelerating, destroys the health of populations.” We do not usually repair them (because the benefits are high and because economic crises are not “good for health”) but it is so. Can something similar happen to mental health? It is a plausible hypothesis. As we explained a few weeks ago, ‘tiredness’ has become something ubiquitous in our societies. Practically half of the working population or they feel high levels of stress or have suffered burnout. We have built some social environments where a hyperproductivity centered lifestyle prevails (Toxic productivity), multitasking and permanent overload; where “feel the pressure of being productive at every moment of the day – always a list of slopes and guilt for not fulfilling it -” has become the new normality. And in a source anxiety, insomnia and extreme exhaustion. Losing all that can be a way to recover everything else. In fact, what they have demonstrated again these twelve hours of darkness is that, For many people, it is. But it also demonstrates the difficulty we have to ‘take control’ of our own life imbued as we are in increasingly complex socio-economic systems: only a historical event seems to give ourselves to recover it.

Every week, millions of flies are released on the Valencia Community and, although it does not seem like it, it is a sensational idea

by

The Valencia war against the Mediterranean fruit fly dates back more than thirty years and is A constant reminder That going to war against an insect is never easy. It is not a reminder that is needed, the truth. Hundreds of regions around the world fight their particular conflicts with All kinds of insects, fungi or bacteria. If Valencia is important, it is something else. For a factory in caudete of the sources. An army of flies. Since at least 2017, the one we know today as Valencian Center for Genetic Fight It has been releasing hundreds of millions of flies weekly to combat pests. The technique is not new, but in this Valencian municipality they have led it to its maximum expression. Not for nothing is the largest bioplant in Europe and the second largest in the world: a reference in what is called “sterile insect technique”. Sterile insect? Yes, it is “a method of biological pest control that is based on raising males of the same species to fight that they are sterilized by irradiation.” These sterile males They are released to the fieldwhere they compete with wild males due to mating with females, “reducing plague levels by not giving rise to offspring.” Is a solution that “has been used in agriculture of multiple countries and in various flies and beetles. In addition, it is studied to fight against mosquitoes, in particular the Aedes“vectors of diseases such as dengue and chikungunya.” And is it viable? According to the Valencian example, it seems that. Although the regional government Spend about eight million Of euros a year, it has become a key piece in the defense of a sector that moves more than 10,000 million only in the region. As explained in the country: “In recent years there has been a very pronounced decrease in hectares of citrus treated with chemicals through aerial media (from about 330,000 at the beginning of the 21st century to just a few thousands of hectares today).” That is, it is a relatively cheap and quite effective project that also allows Very specific interventions And safe: “Since sterile males generally only appear with females of their own species, little effect on ecosystems is expected, unlike insecticides, which are toxic to many different species.” An increasingly present future. A few years ago, Manuel F. HerradorProfessor of the UDC Civil Engineering School, he said that in the future, they will be horrified how much of our way of building was summed up in two words: brute force. Something like this will happen when technology historians look at how we cultivate during the 20th century. Now, little by little, we are recovering (and creating) other ways to intervene in the nature much more intelligent, powerful and effective. Font caudete is just the beginning.

There was a time when we thought the birds migrated to the moon. Until an arrow released in Africa fell in Germany

by

Spring is a time that I always liked. Not for the Horrible processionarybut for the return of the swallows And, above all, of the storks. After a long winter, They return home to nest. Imagine the surprise if, one day, one of those stork appears in your locality with the neck crossed by an 8 -centimeter arrow. Stop imagining because that happened in 1822 in a German city. And far from being an anecdote, it became a key event to unravel the mystery of why birds They disappeared in winter. The doubt. Now it is no mystery and it is something that we learn at school since childhood, but not so many centuries, people did not know why, good at first, the birds were in autumn and reappeared in spring. Those Migratory processes in which even the smallest of the birds rEcorren thousands of kilometers without stopping They were not understood, which forced the thinkers of the time to launch hypotheses and theories that, in the absence of evidence, since they were accepted without further ado. One of the answers was evident. And it could be none than … Alien birds. That is what thought Charles Morton, a Harvard academic who, in the seventeenth century, suggested that the reason why some birds disappeared in winter was because they migrated … to the moon. Most likely you have raised your eyebrow thinking something like “impossible, they could not be so illusory”, but you have to put into the skin of someone who had no way to check the phenomenon and it was still an answer to a real mystery. Because what they knew was that they disappeared for months, but not the place they were going to. And as they saw the moon from Massachusetts, but not Colombia, because the answer was clear. But don’t believe it was the only crazy theory of the time. Aristotle, already in the IV AC theorized about the possibility of being transformed into other species or even shuffled over his hibernation underwater. Morton rejected this idea because it was too fantasy (not like his, of course). The arrow. Morton even calculated that the trip to the moon had a month away and another back, sleeping much of the time and surviving thanks to his body fat. The truth is that, in the absence of better theories, it was not bad (despite my jocular tone, we talked about the seventeenth century and the media they had). However, little by little the idea that these European birds were going to other places during the winter. And the definitive test was brought by a stork. A good day of 1882, north of Germany, someone shot a stork, who fell down and with a capital surprise for those present: he had an 8 -centimeter arrow through his neck. The question was no longer how I could fly with such a breakdown, but where the arrow had come from. Brava PFEILSTORCH. Thus, they took the body of the stork to the University of Rostock, where the researchers examined the projectile and concluded that it was an arrow belonging to some group in the center of Africa. As it was impossible, or tremendously unlikely, that someone launched something like that on European soil, the response became evident: that stork had traveled more than 3,000 kilometers from the point in Africa in which winter had passed and where it was killed in Germany. Baptized as PFEILSTORCHIt was dissected and preserved in perfect condition in the Zoological Collection of the University of Rostock thanks to its undeniable importance in the world of science and ornithology: it was confirmation to the suspicions that, indeed, migratory birds or became anything else, nor slept four months underwater or went to the moon: they traveled to the warmest places during the European winter. Clue. After Pfeilstorch (which means “Flechy stork” or “storks crossed by an arrow”), they found more specimens In Europe with the same characteristics: arrows stuck somewhere in your body. This is not so uncommon in large birds, which show great resilience to wounds that do not compromise flight or its basic functions. Once they are injured, if not seriously, the wound stabilizes and the bird can continue with its life. With the inclusion Of the rings on the legs of the birds by the Danish HC Mortensen in 1899, the researchers systematized the study of specimens to verify that those who flew from Europe before winter, disappeared and then returned, were the same. Thus, we can say that this arrow launched in Africa that landed in Germany was the first bird monitoring system, a coincidence that allowed obtaining the first conclusive data on the migratory practices of the birds.
