The crazy story of the Galician woman who registered El Sol before a notary, sold plots online and then took eBay to court

To the French monarch Louis XIV he was known as the sun kingthus, with a capital letter and all its absolutist pomp. Strictly speaking, that title, however, belongs to another person, and it is not even the priest king. Cuahtemocgreat governor of the Aztecs, nor the Egyptian emperor Amenhotep III. If there is a lady and sovereign of the Star King—or at least that is what she maintains—that is Angeles Durana Galician who one fine day in 2010 decided to do something that no one else had done in thousands of years of human history: she left her house in Salvaterra do Miño, in the Vigo region, and stood in the office of a notary to draw up an official record that she, and no one else but her, declared herself the legitimate and authentic owner of the sun. When the good notary heard her, he couldn’t help but laugh, but he had no choice but to consult with his professional association and, in fact, sign a record of what that lady said. Since then, the story of Ángeles Durán has taken on delirious overtones, worthy of a good astro-legal thriller.I solicited. I, owner of the Sun This is how Ángeles Durán has proclaimed herself, a Galician who in 2010 surprised the world by proclaiming herself the owner of the Sun. And no, we are not speaking figuratively. The news advanced it in its day The Voice of Galiciawhich recounted how Durán went to a notary in a neighboring town, in the Vigo region, to draw up a record that she was the legitimate owner of the axis of the Solar System. If that became news—and it did, so much so in fact that it jumped to foreign media— it was not so much because of the occurrence itself as because of the result. Durán left the office with a document that he later did not hesitate to use. pose for the cameras. “I am the owner of the Sun, a star of spectral type G2, which is located in the center of the solar system, located at an average distance from the Earth of approximately 149,600,000 kilometers…”, proclaims the minutes of statements with the notary’s seal. The Galician newspaper explains that the official made him laugh upon hearing Durán’s claims, but he still consulted with his school and ended up attesting that the woman in front of him declared herself the legitimate possessor of the Sun. Since then many things have been said about Durán: that he is lawyer and psychologistwho at that time served as judicial expert and even, as published The Voice in 2022, who lives in Italy and is focused on preparing a book about the British royal family. One of the latest news that is known about her is that she is dedicated to composing “spicy and erotic songs” and who has released an album. What there is no doubt is that Durán dedicated time and effort to planning her strategy to proclaim herself the owner of the Sun. Whether more or less correct, the undeniable thing is that her request was based on a legal argument that she raised at the time and still maintained in 2019. before the cameras of Cuatro. Going back to Roman law The Galician law basically rested on two legs: a legal vacuum and a legal figure that dates back to Roman law. The first is related to the international agreement that establishes that no country can appropriate the planets. The key for Durán is in that nuance: that it affects the states would not imply, he maintains, that it extends to individuals. The second key is the usucapionwhich allows you to gain real rights to those elements that have been enjoyed for a certain time. And Durán had decades benefiting daily from the Sun’s rays. Like the other almost 8,000 million people who reside on this wide planet, true, but no one else had thought to raise it like this in a notary office. The law is made, the trap is made. At least that’s what Durán thought. “I have not bought the Sun because no one has sold it to me. What I have done is a deed for what is called usucapion,” I insisted in 2019 during an interview in which he assured that this figure can be used “by electromagnetic apprehension.” The truth is that Durán has not been the first to do something similar. Decades ago an American businessman, Dennis Hopeclaimed that he had found a legal loophole that allowed him to claim sovereignty of the Moon. His argument was very similar to that of the Galician: Hope was based on an old law from the 19th century, of the American pioneers, and that the Outer Space Treaty It does not affect individuals. The most curious thing is that the Sun is not the only property that Durán has claimed, although it is certainly the one that takes the cake in size, implications and impact. The Galician has made other equally curious visits to the General Registry of Intellectual Property. The World and The Country They have echoed how he came to record Tarzan’s cry or “the longest score in the world”, 24,000 million measures and related to telephony. “Every time you dial a number, notes are ringing and no one has recorded them,” explained in 2010: “If you mark 1, 2, 3, 4, 5, you are making a few measures and all the possible combinations, all of them, I have registered in my name.” A little plot in the sun… Durán was not satisfied with proclaiming herself the owner of the Astro Rey. He decided to go one step further, cutting up the vast expanse of the star and selling plots on eBay. On the first day he managed to market nearly a hundred stellar plots. According to explained in his day10,000 solar portions were offered, each accompanied by its respective certificate. For one euro, anyone could get a piece of star. … Read more

a poncho turns its soldiers in Ukraine into an invisible army

Last October Ukraine I remembered to his troops that Russian soldiers had come up with a new infiltration system. After the helmets with antennathe lures and the optical illusionsMoscow had found a way to appear among the Ukrainian forces “out of nowhere”. Now, in a new unprecedented twist in the conflict, Russia has found the closest thing to an invisibility shield. From the video game to the fight. Something very similar to what we saw in the Metal Gear saga, then called optical camouflagehas appeared in the conflict in Europe. The war on the Russian-Ukrainian front has seen a tactical evolution that has shifted classic protection (armor and vehicles) towards mobility and thermal stealth: Russian assault forces have adopted ponchos or thermal tarps (the so-called “invisibility cloaks”) as an essential element to minimize the infrared signature and allow infiltrations on foot in the wide swath controlled by the drones. There is no perfect thermal concealment, but the difference between being detected or not can decide the life of an assault group. That’s why these clothes, combined with night movements and the use of specific environmental conditions, have become a central tactical tool that, in practice, today protects more than many armored vehicles against the aerial threat of reconnaissance and attack. Tactical evolution. Thermal tarps are blankets made with reflective layers and materials that accelerate heat dissipation, their purpose is approximate the temperature superficial of the human body to that of the environment to reduce contrast that thermal cameras detect. However, its effectiveness depends of multiple factors: quality of the material, contour sealing (bare feet and hands are detectable signs), weather conditions and, above all, the time of day. The so-called as “thermal crossover” (two brief daily periods in which vegetation, soil and air have similar temperatures) reduces global thermal contrast and offers the optimal window to move forward without standing out, while fog, rain or humidity can complement that invisibility. Improperly used, ponchos generate “cold spots” that attract attentionbut used well, multiply the probability of achieving tactical objectives. Limitations and learning. It must be clarified that thermal tarps do not make the attacker invulnerable. Experienced drone operators look for subtle signs (bare feet, movement under the cover, small thermal disturbances) and learn to distinguish behavioral patterns that reveal infiltrations. In addition, there are low quality materials and training errors: there are cases of soldiers who tried to camouflage themselves in broad daylight or with inappropriate ponchos and were detected. The tactic is therefore effective but fragile: it works best en masse, under optimal conditions and when the adversary lacks sufficient alternative sensors or personnel on the line. US Marine Corps uniform with built-in thermal camouflage Countermeasures and tactical recovery. To counteract these infiltrations, the solution it is not unique: involves deploying complementary sensors (acoustic, magnetic, seismic) that do not depend on the thermal spectrum, or reinforcing minefields and physical barriers, densifying human or robotic presence in exposed sectors, or even improving doctrine multisensory surveillance and train detection teams to identify minimal signs of intrusion. In strategic terms, Ukrainian forces agree that the response involves combining technology (more sensors, better integration) with greater territorial occupation, because passive defense based solely in aerial interceptions It is insufficient against equipment that infiltrates at low visibility. Operational implications. The resort to small infiltrated groups reflects broader tensions: troop shortages, accumulated material wear and tear, and an environment where air or drone superiority does not guarantee the security of the rear. For those who attack, the tactics allows you to exploit holes in defense and wear down positions through groups that, although they lose part of their troops, can complete reconnaissance, sabotage or local assault missions. For those who defend it, it forces us to rethink the segmentation of the front and the provision of resources: the balance between expensive sensors and effective personnel, the need for mobile reserves and the growing importance of passive and active containment measures on the ground. Strategic conclusion. If you like, we are facing a tactical transformation where war becomes more granular and less dependent on traditional armor: the multiplication of drones and sensors has revalued thermal invisibility and human mobility, while it has revealed the fragility of conventional defensive schemes. In the short term, the balance favors those who know integrate camouflagemeteorology and discreet logistics. In the medium term, effective defense will require a greater density of heterogeneous sensors, more troops or robotic means on the line and a doctrinal adaptation that combines multisensory detection with physical measures that close the gaps that infiltrators exploit today. In short, in the current field a thermal tarpwell used, can offer an attacker more practical protection than many armored vehicles, and this realization forces us to rethink tactical defense and territory management in a conflict dominated by sensor warfare.

There is already a first crack in Chinese technological optimism: DeepSeek

Chen Deli, senior researcher at DeepSeek, has admitted at a state conference who is “extremely positive about technology, but pessimistic about its impact on society.” It is the first time that a representative of the Chinese company has spoken publicly since February, when its founder met with Xi Jinping after provoking that world earthquake with the launch of R1. And he has done it with that pessimistic outlook. Why is it important. This message comes from a company that the Chinese government has turned into a symbol of technological capacity and resilience in the face of US sanctions. That one of its leaders recognizes great risks for employment is a notable turn in a country where the official discourse is usually triumphalist. The facts. Chen participated in the World Internet Conference in Wuzhen along with the heads of five other companies known in China as “the six little dragons” of AI. His diagnosis has a gloomy tone: in one or two years, AI will be good enough to start replacing human jobs. In a decade or two it could take care of the rest. “Society could face an enormous challenge,” has said. “Tech companies need to take on the role of advocate.” Between the lines. This is not an American CEO peddling apocalypse smoke to inflate his valuation. In China, the State regulates technology with a firm hand. When Sam Altman says that AI will “probably lead to the end of the world, but in the meantime there will be big companies,” it sounds like marketing. When a DeepSeek executive says it at a conference organized by the government, after many months of silence and after its founder met with Xi, it sounds like a party line. The context. DeepSeek exploded in January with DeepSeek-R1a low-cost, open-source language model that was on par with American leaders. Since then, absolute exit. The founder, Liang Wenfeng, has appeared only once in all this time: at a televised symposium with Xi Jinping in February. Neither Liang nor the company has made public comments since then, and they have skipped all major Chinese tech conferences. Yes, but. While sending this message of caution, DeepSeek is in the process of consolidating itself as a cornerstone of the Chinese AI ecosystem. Chip manufacturers such as Cambricon and Huawei have developed hardware compatible with their models. In September, the company launched an “experimental” version of its V3 modelnotable not so much for its efficiency as for creating an alternative to NVIDIA’s CUDA API and its support for Chinese GPUs. In August, the simple announcement of a model optimized for national chips shares of the sector skyrocketed in the local market. And now what. Xi Jinping has proposed a little over a week ago on the APEC forum that there should be a global body that governs AI, making it “a public good for the international community.” Now a DeepSeek representative talks about AI as a potential threat that requires a unified approach from the technology sector. The narrative is shifting from triumphalism to preventive regulation. Featured image | Xataka, DeepSeek In Xataka | We believed that no open model could outperform GPT-5.

China’s “sorpasso” is now a real possibility

2025 has been a lost year for NASA. No rockets have exploded, no spacecraft have crashed, but political instability, lack of leadership and budget wars have decimated the morale and operational capacity of the US space agency. The most absurd thing of all? self-inflicted harm has had the opposite effect whom the United States government was looking for. Nobody at the wheel. It all began on January 20, 2025, when Biden-era administrator Bill Nelson resigned as head of NASA. Janet Petro, director of the Kennedy Space Center, took over as acting administrator. In his six-month term he dedicated himself to abide by Trump’s divisive policiesstarting with eliminating the space agency’s Diversity and Inclusion office. donald trump had nominated for the permanent position of administrator to the young billionaire Jared Isaacman, who flew into space twice with SpaceX. Isaacman, who was seen as a commercial sector accelerationistpassed his confirmation hearing in April 2025. Everything seemed done. However, on May 31, shortly before Trump will exchange insults with Elon Muskthe White House abruptly withdrew his nomination. The official reason, published by Trump himself in Truth Social, was Isaacman’s “prior associations,” particularly his donations to Democratic candidates. The Duffy era. NASA was left adrift. On July 9, Trump named his Secretary of Transportation, Sean Duffy, as acting administrator. Duffy, a former congressman with no aerospace experience, kept his Cabinet position while running NASA, and is said to have came to maneuver to integrate the historic space agency under the Department of Transportation. But Sean Duffy’s stellar moment occurred on October 20, when he set the goal of returning to the Moon while Donald Trump was president. In order to land astronauts on the lunar surface before China does so for the first time in 2030, Duffy reopened HLS contract that NASA had granted to SpaceX. Other companies such as Blue Origin and Lockheed Martin will compete with SpaceX’s Starship to transport astronauts from lunar orbit to the surface of the Moon in the first manned lunar landing since the Apollo era. Life takes a thousand turns. In a twist that well illustrates NASA’s lost year, and despite Duffy’s efforts to show off to his president, on November 4, Trump reappointed Jared Isaacman as administrator. The timing coincides with an improvement in Elon Musk’s relationship with Donald Trump, suggesting that donations to Democrats did not have as much to do with Isaacman’s truncated career as the Elon-Trump feud did. But even as NASA’s power vacuum nears its end, the agency faces even worse problems. The White House budgets for 2026 included a 24.3% cut to the space agency’s overall funding, including a 47% cut to the scientific budget. The lack of approval of budgets has also, ironically, had a catastrophic impact for the agency: 15,000 NASA employees (85% of the staff) were suspended without pay due to the government’s “shutdown.” The shutdown has delayed all kinds of developments, including the lunar program and the Mars sample recovery mission, in which NASA is in direct competition with China. Meanwhile, China. NASA’s comings and goings have allowed the Chinese space agency to close the gap. After becoming the first country in the world to bring back samples of the far side of the Moon with the Chang’e-6 missionChina is on track to become the first nation to bring samples from Mars with the Tianwen-3 mission. The great irony is that, with NASA’s lost year, it is also beginning to be very feasible that a Chinese astronaut will set foot on the Moon before the next American moon landing occurs, which the White House wanted to avoid with its scientific budget cuts and its improvised leadership changes. The “sorpasso” is no longer a distant prediction. US inaction in 2025 has helped put China on that trajectory.

Brazil has been pursuing high-speed trains for 20 years. Now it will have the first in South America

If we see the list of countries with the most high-speed train linesChina is the one cut the codwith Europe and Japan also on the crest of the wave. However, South America is a territory that neither punctures nor cuts. That’s about to change and, although there are several projects in different countries, the first high-speed train in South America will be in Brazil. And it promises to revolutionize transportation in one of the country’s key corridors. It is not (fast) train territory. Connecting South America by train is extremely complicated. Not only do they have a complex topography with mountains and jungles to overcome, but also an enormous geographical dispersion, political instability in some countries and priorities that have changed with different governments. Currently, the territory is experiencing a revolution. There are countries like Mexico either Chili who are waging war on their own with internal projects, but also a project known as ‘Bioceanic Railway Corridor‘ which will unite the Pacific and Atlantic and connect the port of Santos in Brazil with that of Bayóvar in Peru. Apart from that line, Brazil has its own plans. The Brazilian TAV. The Brazilian high-speed project is not without controversy. The TAV (or High Speed ​​Train) began to take shape in 2004. Named ‘Bandeirantes Express’, the idea was to connect São Paulo with Campinas. It came to nothing and in 2007 it was shelved, but with the arrival of Lula da Silva and the perspective of Soccer World Cup 2014HE relaunched. It would have been the perfect setting, but the dates were not met either and, from lost to the river: we took it back to 2016 for the Rio Olympics. Spoiler: it went wrong due to financing problems, doubts about profitability and, evidently, a lack of interest from the private sector that was not clear about how to recover the investment. Chronology. It would have been the first high-speed train in South America, but it seems that it had not said its last word, because in 2023, the private company TAV Brasil got by the National Land Transportation Agency the authorization to link the main cities of the country: Rio de Janeiro and Sao Paulo. The 99-year concession allows them to plan, build and operate the line that, if all goes well, will connect the two cities with intermediate stops between Sao José dos Campos and Volta Redonda. The investment is not clear and is estimated at about 60,000 million reais, which is about 11,000 million euros, and points to a ticket price of around 85 euros for a complete trip. TAV Brazil has announced the following calendar: End of 2026 for the conclusion of feasibility studies. 2027 as the start of construction. 2032 as commercial commissioning. The train. The intention is that the machine reaches speeds of 320 km/h, which would more than meet what is considered the high speed standard (250 km/h) and will allow travel the 400 kilometers between the two megacities in just one hour and forty-five minutes. This is a considerable reduction compared to a current road trip that takes about six hours. Interests. The big question is who will build the system… and the trains. This is a high-stakes project and, as in other parts of the world, geopolitics plays an important role. Historicallythe project has attracted the interest of companies such as the Spanish CAF or the French Alstom (in contention right now for the train in Belgian), but also from Siemens and other leading companies in the sector. TAV Brazil has not closed its doors and is talking with both Spanish companies and Arab funds and, of course, with China, which is becoming a global touchstone in the railway segment. They are revolutionizing Africa, they have a presence in the deployment of the line that will cross South America from Brazil to Peru and getting a piece of the Brazilian high-speed pie would mean another lucrative hit on the table. In any case, the one in Brazil and other projects seem to be beginning to shape the railway future of a Latin America that has had plans for decades, but for various reasons they have not come to fruition.

China has a plan to repeat with cars what it already did with cell phones. And that plan has already begun

It is more than likely that, wherever you look, see chinese technology. Maybe it’s your cell phone, your tablet or your television. You may be surprised that your microwave with a Japanese or American name is actually made by a chinese company. Or your refrigerator, air conditioning, whatever. China has conquered the world of technology and that, at this point, does not surprise anyone. Nor will it be surprising that the Asian giant wants to get involved to the kitchen (literally) and, in the case at hand, even our garage. Because yes, China has been promoting a plan since 2015 to lead several key technological industries (which is what it means to be the largest producer of batteries in the world) and one of those industries is the car. And we are already starting to see it. From the mobile phone to the washing machine and the car China understood very quickly that the future of cars was not in combustion, a market largely led by a well-established European industry. but in electricity. China took a shortcut. The state subsidized every stage of the chain, from mines and loading docks to battery factories and start-ups. We have the clearest example in BYD, which went from manufacturing mobile batteries to being the spearhead of the Chinese electric car. The Chinese market, however, is very saturated. Despite its huge population, there are 150 car brands in the country, so competition is fierce. Thus, China began to look outwards. And it went very well. In 2023, China surpassed Japan as the world’s leading car exporter and the next logical stop was Europe. The Chinese proposal was simple: offer technology, design and autonomy at a much lower price than local and Western proposals. Spain was the gateway with companies such as BYD, OMODA, JAECOO, XPENG and MG filling dealerships, something that translates into a considerable drop in average prices of 12%. In just a few years, the market share of these brands has skyrocketed from 2% to 7%, a figure that rises to 14% if we take plug-in hybrids into account.

They can also access affordable financing, free land and subsidiary energy. Companies compete under exceptional conditions with each other, encouraging price cutting and innovation. Not even tariffs can stop China’s advance. China, in fact, has not trembled when it comes to open factories on our continent to manufacture from within and, in the process, sow the seed of a more or less silent conquest.

That a teenager begins to ‘hate’ his parents is something that is in his brain, and science has already found the pattern

If you’re a parent of a teenager, you know: their world revolves around their friends. If you were one of them, you surely remember: parents’ opinion took a backseat. And although it seems that it is a sign of the rebellion that we see normal at this age, the reality is that the guilt is literally found in the brain. The culprit. But when asked what causes this indolence among adolescents? The answer comes from the magnetic resonance imaging that has been applied to the brains of some adolescents. And research shows that, during adolescence, the brain not only changes its interest, but also reconfigures your reward circuits so that the voices of strangers are more gratifying than the voice of one’s own mother. And this is something that explains the fact that adolescents give much more importance to a friend than to their own closest family, and even go so far as to prioritize them above anything else. Although in the end he has a good excuse in his brain systems. The study. To find this out, the researchers didn’t have the teens listen to scolding. They used a more cunning methodology by gathering 46 children and adolescents between 7 and 16 years old who were exposed to listening to recordings of nonsense words such as teebudie-shawlt. The important thing about this investigation was that these meaningless words were spoken by two voices: that of their own mother and that of two women unknown to them. In this way, when the recording was played, the activity of their brains began to be analyzed through functional magnetic resonance imaging (fMRI) to see the parts of the brain that were lighting up with each of the voices that were playing. The results. In the youngest children between seven and twelve years old, their mother’s voice caused a party at the reward centers of the brain, specifically in the nucleus accumbens (NAc) and the ventromedial prefrontal cortex (vmPFC). The interesting thing here is that this activity was much greater than what was felt when hearing the voices of the strangers and it is logical because the mother is the center of her social universe that causes her greater happiness. But things change completely in adolescents between 13 and 16 years old, where these same reward and social evaluation regions showed significantly greater activity for unfamiliar voices than for their own mother’s. In this way, the age that we can consider as a border between them paying attention to their mother and when they are going to completely ignore what they are told will be around 13.5 years. Because. In this case we are not talking about adolescents rejecting their parents, since in a behavioral test they were able to identify mothers’ voices in an almost perfect way. The change is precisely in the valuation of that voice. This neurobiological turn is considered an adaptive process essential for maturity. The teenage brain is being “refreshed” for a new mission: leaving the nest. To prepare for independence, the brain must begin to find new social connections more rewarding. You have to tune in with your companions, future allies and partners. The bibliography. This finding fits with previous models that were made to identify the differentiated stages in social and brain development, where the affective focus passes from the mother to friends and finally to romantic relationships. Recent reviews reaffirm that the reward system in adolescence is especially sensitive to novel social stimuli, and that the maturation of frontostriatal connections modulates these changes. A previous work by the same group had already shown that in childhood the maternal voice has a privileged response in the mesolimbic circuit and the current study extends and completes that model by showing how this pattern is reversed in adolescence. In this way, every time we see a teenager who literally tells his mother that he doesn’t even want to hear her, but spends all day talking to his friends, we already know why: his brain has changed so that he likes it more.

Paris Hilton lost her dog, so she cloned it

Paris Hilton lost her dog, so she cloned him not once, but twice. And he is not the only public figure who has done so. Barbra Streisand was one of the first to clone petsbut the cases of Javier Milei or the American football player Tom Brady are also known. That’s how it is the pet cloning market. A nail clone pulls out another nail The loss of a pet is a very painful experiencefor many people as hard as losing a family member. Science is already looking for ways to extend the life of dogsbut at the moment living as long as humans seems far away. Nor you can make your dog or cat live foreverbut if you have money you can resort to cloning. This is what Barbra Streisand did when her dog Samantha died in 2017. And if one clone was not enough, she asked for two to be made. Paris Hilton also resorted to cloning after her chihuahua Diamond was lost in 2022. Like Streisand, she also cloned her twice. If we look only at the number of clones, Javier Milei, current president of Argentina, has gone too far. In 2017 he cloned his English mastiff Conan not one, but five timesalthough one of the puppies died shortly after. The most recent case involved Patriots quarterback Tom Brady, who confessed in the magazine People Magazine that his current dog Junie is a clone of Lua, his previous dog who died in 2023. ELON MUSK VS JEFF BEZOS: STAR WARS Personality is not cloned There are several companies that are dedicated to cloning pets. The most famous is the American Travel Petswho was in charge of making clones for Paris Hilton, Barbra Streisand and Javier Milei. Tom Brady did it through the startup Colossal Biosciencesdedicated to “de-extinction.” And be careful, because In Marbella there is also a clinic that is dedicated to cloning dogs and cats. The cover of the Viagen website The process begins with the pet tissue collectionwhich should be done either while the pet is still alive or immediately after its death. Using these cells, they create embryos that are implanted in a surrogate mother. The resulting animals are genetically identical to the original, but that does not mean they will behave the same. Barbra Streisand admitted in an interview in Varietythat The clones had different personalities to that of his dog Samantha. On its website, Viagen says the result “shares your dog’s DNA and often the same intelligence, temperament and appearance.” Emphasis on that “often.” How much does this cost You’ve probably been wondering since you read the headline. Travel Cobra $50,000 to clone dogs or cats and $85,000 in the case of horses. These are high figures for most people, but a few years ago it cost twice as much. There are no figures, but in this report from The Atlantic They assured that companies like Viagen they have a waiting list and thousands of clones of pets, but also horses or cattle, have already been produced. A striking example is that of polo player Adolfo Cambiasowho has more than 100 clones of his best mare. Although feasible, animal cloning raises ethical questions, mainly about the well-being of the animals involved in the processboth the clones themselves and the mothers in whom they implant the embryos. It is well known that purebred females, both dogs and cats, are often exploited and subjected to continuous pregnancies and then sell the puppies. The difference here is that they create clones from implanted embryos. On the other hand, there is the question of purchasing animals, in this case clones, when the shelters are saturated with animals waiting for an adoption. Only in Spain it is estimated that 33 pets are abandoned per hour. Finally, a personal contribution, it will be a year soon since my kitten Piñón died. We had a very special bond and his loss was very traumatic because he was still very young. I miss it as if it were the first day, but it would never occur to me to put my grief above the well-being of other animals.

This is how science has unraveled the mystery of Lake Tefé

The historic drought and heat wave that hit the Amazon in 2023 caused extreme warming and unprecedented in its waters, with devastating consequences that we are seeing today. A new study published in Science details how water temperatures in key lakes reached lethal levels, causing high mortality in fish and especially river dolphins. Very high temperatures. A priori we may think that heat waves just as they come will go away without leaving any consequences. But the reality is very different, since in the Amazon, of the ten lakes that were monitored, five exceeded 37ºC during the day and there was one that reached 41ºC as if it were a spa pool. This extreme heat wasn’t just skin deep; It penetrated the entire water column, approximately 2 meters deep, eliminating any fresh refuge for aquatic life. It was literally left uninhabited. Epicenter of the tragedy. Lake Tefé, which is normally more than 7 km wide, became the focus of national and international attention after its surface area will be reduced by 75% between September and October 2023. It is literally a consumption never seen before that surprised the inhabitants of the area and also the animals. This drastic reduction in water coincided with a “massive and unprecedented mortality” of river dolphins. In a short interval, 209 dolphin carcasses were found (both from the Amazon River and Tucuxi). And precisely, the study points out that only on September 28, 2023, when temperatures reached 39.5 °C for the first timeseventy dolphin carcasses were found. The researchers also observed extreme daily temperature variation of up to 13.3°C, meaning the water went from hot tub-like heat during the day to drastically cooling at night. completely altering the conditions of the system. And living there becomes really complicated. What caused this extreme heat. The study used models to identify the culprits behind this warming. It was a “perfect storm” of factors that coincided such as high solar radiation due to completely clear skies that could not stop the sun. But the reduced depth of the water or the low wind speed also intervened, which generated less cooling due to evaporation. A long term problem. While the 2023 event was extreme, it is not an isolated incident. Study reveals worrying long-term warming trend in region, Based on satellite estimates, between 1990 and 2023, the lakes in the Amazon region have experienced a temperature increase of 0.6 degrees per decade. A great ecological crisis. The impact was not limited to the dolphins. The study also documents significant fish mortality. All because of the fact that they have a fairly narrow temperature tolerance range, meaning that the moment there is an increase, even a slight one, in temperature, they are finished off. For human populations, the consequences were equally serious. The drought and extreme heat managed to isolate thousands of people in riverside communities, leaving them without adequate access to food, drinking water and medicine because maritime transport is also severely affected.
