secret

Before the Incas, a civilization created an impregnable empire in the heights of Peru. His secret: feces

by

The coastal desert of southern Peru is one of the most arid environments on the planet, but this was not an impediment for a civilization that was able to prosper here with more than 100,000 people and before the arrival of the Inca empire. Their secret here was seabird guano, and science has now just demonstrated to what extent bird dung was the real economic and demographic driver. of the Chincha Kingdom. The feeding problem. During the Late Intermediate Period, approximately 1000 to 1400 AD, the Chincha Valley became a pre-Inca superpower. But to sustain its growth and maintain some 30,000 workers, it was logically necessary to produce food on a large scale, and more specifically corn, which was the basis of their diet. The problem is that the Peruvian coast is not exactly the most fertile place in the world, so the population faced a serious food problem. But here the solution was to look at the sea and the islands full of guano birds, and more specifically towards their feces and their ability to fertilize. Something that made them begin to prosper and become very strong in the region. The confirmation. To confirm this theory, a scientific team analyzed stable isotopes of carbon, nitrogen and sulfur in 35 ancient corn cobs and 11 seabirds found in tombs in the Chincha Valley. Here it was possible to see how clearly plants that absorb nutrients from fertilizers derived from marine animals show a very specific chemical signature with high levels of nitrogen 15. The results. Here the conservative limit to determine the use of guano in the experiments was located at a value of +20%, but in Chincha corn the average values ​​were +19.4%, reaching peaks of up to +27.4%. Thanks to radiocarbon dating, scientists have been able to place the beginning of this large-scale agricultural practice around the year 1250 AD.a date that coincides millimeters with the rise and expansion of the Chincha Kingdom. What we knew. Modern chemistry only confirms what archeology and history already hinted to us, since the iconography of the time is full of references to this agronomic practice. In textiles, friezes and ceramics of the Chincha culture, corn appears constantly represented alongside guano-producing birds, such as the guanay cormorant, the Peruvian booby and the pelican. Even Spanish colonial chroniclers, such as Inca Garcilaso de la Vega, recorded this practice when describing how the indigenous people applied the guano to corn through irrigation systems and they documented the strict taboo laws later imposed by the Incas to protect these birds that for them were the focus of fertilization of their fields. This is why killing a guano bird or disturbing its nests was a crime punishable by death. A great revolution. The mastery of guano technology not only filled the stomachs of the Chincha, but made them a key player in Andean geopolitics. In this way, when the Inca empire began its expansion, they did not conquer the Chincha because of their great strength, and instead they formed a strategic alliance. The Chincha here had control of the precious fertilizer and dominated the maritime trade routes, exchanging the guano for luxury goods such as prized shells. Spondylus. This agricultural base allowed the Chincha Kingdom to negotiate its integration into the Inca empire from a position of power and privilege.

We have found the “switch” of cellular aging. The secret is called protein AP2A1

by

Regenerative medicine has a very clear objective ahead today: to look for the ‘button’ that can stop aging and allow us live much longeror at least have a better quality of life when we reach certain ages. And here the Japanese have a lot to say with a discovery that gives us more clues about how to preserve our cells much better. A new study. Everything that has to do with living a little longer, the truth is that it causes a little stir in the scientific world, and the article published in January 2025 in the magazine Cellular Signaling it was no wonder. Here it was shown how a team of researchers from Osaka University managed to identify a protein that literally acts as a cellular senescence switch called AP2A1. Our cells. Just as aging can be seen aesthetically, our cells also age through a process of senescence. Upon entering this state, the cells stop dividing, but do not die, since they become larger, more rigid and adhere strongly to their environment. And here a team of scientists has discovered the exact mechanism that causes this. Here the study has pointed to a protein as the culprit: AP2A1. A molecule that acts as a kind of biological transport truck that moves another protein, called β1 integrin along the fibers of the cell. That is why, over time, this process strengthens cell adhesion, causing the cell to become rigid and “old.” The revolution. The important thing here is that if the function of AP2A1 is suppressed in old cells, the biological clock reverses. That is, the cells decrease in size, lose rigidity, drastically reduce the classic markers of aging and proliferate and migrate again. Basically, they rejuvenate themselves. Furthermore, it has also been seen that if this protein is overexpressed in young cells, the result is great aging that accelerates. Your potential. Here the scientific team has seen that AP2A1 is not only emerging as a great marker that measures a person’s aging, but also acts as a direct therapeutic target. That is why some specialized websites such as Fight Aging! already analyze how blocking AP2A1 prevents inflammatory signaling typical of senescent cells. In this way, if we manage to inhibit this protein in the future, we could develop “anti-senescence” agents capable of extending our healthy life expectancy and combating age-related diseases, such as osteoarthritis. A long way. For now, this is something that has been estimated in cellular models in a dish in a laboratory, but it still remains to be seen how it works in the human organism with all the factors that intervene on a cell that is not isolated. What is clear is that the discovery of AP2A1 is a spectacular milestone in cell biology. We have basically found the button that controls the size and youth of cells in the laboratory, but the next big challenge for science will be to find out if we can press that same button, safely, inside the human body. And for that, there are still many years of research left.

Tokyo is one of the few cities in the world that has managed to maintain housing prices. His secret: build

by

“If you can’t solve a problem, make it bigger.” This oft-repeated maxim (and mistakenly coined for Dwight D. Eisenhower) can be good advice when it comes to housing: Expanding the scope of a problem can make new solutions possible. Japan is the world’s best example of an advanced industrial democracy with abundance of affordable housing with low carbon emissions. To build. The key to Japan’s success is its unusual degree of national control over zoning and building rules. Centralized authority trumps local housing obstructionism. Tokyo builds more housing in a year than all of California or all of England, which have 3 or 4 times its population. In the largest megalopolis in the world, the way Rents stay low in the long term is to build. National decisions. The political scientist Grant McConnell wrote on the classic articulation of the view that the national government is more likely to solve difficult problems than state or local governments. Small can be beautiful, the reasoning goes, but it can also be provincial, backward and oligarchic. This logic fits well with the housing issue: Putting much more at stake, all at once, in one big fight, rather than piece by piece in hundreds of separate local fights, could disrupt the housing war. More homes around the world. The world has provided some examples of this. Japan has had extraordinary success in housing construction. He has long been a leader and expanded his leadership even further in recent years. Germany, Austria and Switzerland have always had good records, behind Japan but still performing well. France has stepped up, at least in Paris. These countries generally employ rule-based (or “by right”) building permit systems: if your plans check the stipulated boxes, building authorities have no choice but to sign. The Anglo-Saxons. On the other hand, English-speaking countries, including Australia, Canada, the United Kingdom, the United States and New Zealand, are lagging behind. Their permit systems are often more discretionarygiving local officials the power to approve or reject buildings at will. In many parts of these countries, especially their large cities, housing is expensive because it is scarce. For now, the Anglosphere suffers the worst housing shortages and prices. The Japanese case. The Asian country is the best example of the maxim of “magnifying” problems. Japan’s national government controls the use of land and buildings to a greater extent than national authorities in other countries. This control has grown in recent decades, even as other nations have gone into lockdown. The number of homes built per year in industrial democracies has fallen by more than 60% since 1970, according to The Economist. Meanwhile, housing construction in Japan has remained solid at all timesbroad public interest in abundant housing has triumphed over obstructionism. What did they do? To boost construction and lower prices, Japan redoubled efforts to allow more housing construction. He resorted, in particular, to administrative changes in building codes. “To help the economy recover from the bubble, the country eased the regulation of urban development,” explained Hiro Ichikawa, a construction development advisor. in the Financial Times. “If it hadn’t been for the bubble, Tokyo would be in the same situation as London or San Francisco.” Build, build and build. The results, in abundant housing, low prices and low carbon urban formswalkable and transit-focused, are notable. The city of Tokyo had 13.5 million residents in 2018. But the city built 145,000 new residences that year. Tokyo’s achievement was particularly surprising considering that the prefecture has very little vacant land, so almost all of those 145,000 homes were located in an existing neighborhood. The astonishing pace of housing construction in the capital has continued for years. Tokyo routinely builds more new homes than all of California (which has three times its population) or, in some years, all of England (which has four times its population). It has increased housing construction by 30% since the turn of the century, even as its population peaked and began to decline in 2007. disposable houses. It is true that Japan demolishes houses much earlier than other industrialized countriesso a large portion of their housing starts are replacement housing. But the much criticized Japanese culture of “disposable houses” It is actually one of the secrets of its success. Japan’s rigorous and up-to-date earthquake safety laws, plus a cultural attachment to new homes, mean that tiny houses in Japan often depreciate completely in just 30 years and are replaced soon after. Because housing is renovated quickly, the country has a much better chance of installing larger buildings. In parts of the US, where buildings typically have an economic life of 100 years, you only have one chance per century to replace a house with an apartment building. In Japan, you get three. More housing. The prefecture has tripled its stocks of housing in the last 50 years and has expanded the number of residences in the city by about 2% annually since 2000. In fact, its overall housing unit growth rate was three times faster than London or New York in the 2010s. Among the 14 megacities around the world, only Singapore and Seoul surpassed Tokyo in the pace of overall housing growth. Thanks to the Japanese program to govern housing, Tokyo Prefecture and the world’s largest metropolis have completely avoided residential closures. Japan seems to have learned the maxim attributed to Eisenhower: if you can’t solve a problem, make it bigger.

We have been reading philosophers from the West and Asia for centuries in search of the secret of happiness. Turns out the Aztecs had it

by

Each course Lynn Sebastian Purcell, philosophy professor, repeat the same experiment. After reviewing the passage from the ‘Odyssey’ in which Ulysses renounces an eternal life of pleasures with the nymph Calypso to search for his wife and son, the teacher presents a dilemma to his students: How many would do the same as the king of Ithaca? “How many of you would reject immortality and a pleasant existence on the condition that you never see your family and loved ones again?” defiant spear Purcell to the classroom. The answer is always the same: nobody. The ‘Odyssey’ is an epic poem that connects with the Greco-Latin tradition, but in reality that particular passage about Ulysses summarizes well the vital philosophy of a civilization that lived thousands of kilometers from the Ionian Sea: the aztec. Goal: happiness. I don’t know exactly who you are, but it’s quite likely that you, me and the more than 8 billion Of people who share this world, we agree that it is desirable to have a happy life. Logical, right? Happiness is one of those golden nuggets that philosophy has been searching for for centuries. I did it in times of Epicurus and he does it in our days. In fact one of the most famous treatises of Bertrand Russella famous philosopher of the 20th century, is titled with a phrase that is quite a proclamation: “The conquest of happiness”. The lesson of Ulysses. However, it is one thing to aspire to happiness and another to decide how to achieve it or even what exactly happiness is. This is where the passage from the ‘Odyssey’ of the nymph Calypso. If it’s just about seeking happiness, Ulysses already had it, right? If we agree that the goal is to be happy (just like that), isn’t it a good idea to spend an eternal life, free of illness and deprivation, living with a goddess on a distant paradise island? Why does Ulysses decide to return to the sea… and his hardships? “Let it be worth it”. Ulysses’ attitude (like that of Purcell’s students) connects fully with a philosophical ethic that for decades has gone unnoticed in the West: that of the pre-Columbian Aztecs. For them, remember the teacherwhat humanity really seeks is not so much a life full of happiness and pleasures as “an existence that is worthwhile.” That’s the goal. The texts that are preserved and tell us about how the Aztecs saw the world show that for them humanity faced “an existential problem,” In Purcell’s words: a brief, fickle existence, during which it is impossible to control everything just as it is not to skate in a quagmire. “Slippery is the land”. “What they wanted to say is that, despite our best intentions, our life is prone to error, failure in our objectives and, therefore, to ‘fall’, as if we were going to end up in the mud. Furthermore, this earth is a place where joy comes mixed with pain and setbacks,” explains the professor in an article published by the Philosophy Association (APA). In it he remembers that this entire conception of the world can be summarized in a popular saying: “Slippery, slick is the earth”“slippery, slippery is the earth.” Wait, Aztec philosophy? Exact. It has not been easy to survive and in the West we may not have paid enough attention to it, but that does not mean that the pre-Columbian Aztecs created a valuable philosophical corpus, with different currents and treatises. “We have many volumes of his texts recorded in his native language, Nahuatl,” claims Purcell at the BBC. “While few of the pre-colonial hieroglyphic-type books survived the Spanish burnings, our main sources of knowledge derive from the records made by Catholic priests until the early 17th century.” A different vision. Thanks to them we preserve codices with sayings, exhortations, poems, dialogues… different manifestations that essentially tell us about the same thing: how the Aztecs who lived between the 15th century and the beginning of the 16th approached existence. Good example is the ‘Florentine Codex’a bilingual work by friar Bernardino de Sahagún on pre-Columbian knowledge. His legacy is not only interesting because of what he tells us, it is also interesting, Purcell claimsbecause it opens our eyes to “another pre-modern culture with an ethics of virtues”, one different from the legacy of Aristotle or even Confucius. “Place of joy with fatigue”. At this point the question is obvious… If the Aztecs believed that what humans really want are lives “worthwhile”, even more than joyful and pleasant existences, how to achieve it? How to face the passage through this world, “a place of joy with fatigue and pain”, as an Aztec passage says? The key is in a recipe with four ingredients, four “levels” that allow us to enjoy a rooted life, “neltiliztli”. Continuing with the metaphor of existence as a swampy terrain, full of mud, the idea is to take root to gain a foothold. And how to achieve it? To begin by ‘rooting’ in one’s own body. As Purcell explains, the figurines and descriptions we preserve of the Aztecs show us that they liked to exercise their bodies. In fact, they had a regimen of activities aimed at stretching and strengthening the body that is partly reminiscent of yoga. Rooted in the body, it had to be done at another level: the “psyche”, seeking a balance between the heart and the head, desires and judgment. “Only in the middle can you go, only in the middle can you live”, advises one of his works. Social creatures… and of the earth. In an article Published years ago in Aeon, the scholar of Latin American philosophy points out two more levels at which those who want to achieve a rooted life must work, “neltiliztli”, a term that is also used as “truth” and “goodness.” The first level is “rootedness in the community.” We live surrounded by people, in societies in which we play a role that connects us with others and activates the … Read more

the secret so that cheese doesn’t taste like fish

by

You go to a store to buy a refrigerator and see that, in addition to having very different prices, one of them has a double cold circuit. You choose the cheapest one without taking into account that with the most expensive one your food may taste better. Why is this happening? Today we are going to explain How traditional refrigerators differ from Twin Cooling refrigerators. How a traditional refrigerator works Traditional refrigerators operate through a closed refrigeration cycle. The main objective is to extract heat to the outsideand it does so through two condensation and evaporation coils respectively, which are tubes through which the refrigerant fluid circulates. These two coils are placed between a compressor and an expansion valve. To understand it, in the traditional system the dry and cold air from the freezer is mixed with that from the refrigerator. It is, so to speak, as if it were a single lung for two bodies, which causes odors to mix, there to be no optimal humidity and the engine to turn on regardless of whether we open the freezer or refrigerator compartment. To understand it, the refrigerant fluid travels through the condensation coil to the expansion valve, thus reducing its pressure and temperature. This process causes the liquid to evaporate when it reaches the second evaporation coil, which, as you can already imagine, evaporates the fluid until it reaches the condenser in the form of a gas. In this section, the condenser provides energy to the gas so that it can flow, increasing the pressure to become liquid again so that the heat goes outside through the walls of the condenser tube. As a summarythe cycle through which the refrigerant fluid travels is: condensation coil, expansion valve, evaporation coil and compressor and compressor tubes. This cycle is constant until the refrigerator temperature reaches what we have set on the thermostat. Refrigerators with freezers work in a very similar way. The refrigerant fluid travels first to the freezer areaand once it has reached the desired temperature it travels to the refrigerator area. The compressor ensures that the refrigerator has a different temperature, stopping the fluid before reaching the refrigerator area if the temperature is the same as what we have on the thermostat. How a refrigerator with a double cooling circuit works Refrigerators with a double cold circuit work in a very similar way, but they have a fairly big difference: instead of having one circuit, they have two. To clarify, the fact that it has two circuits does not mean that they consume more electricity, since it is quite the opposite because they are usually more efficient. Because? By having two independent circuits, the engine work is less because it cools only the freezer or the refrigerator, and not both. If, for example, you open the refrigerator in a traditional refrigerator, the cooling fluid has to travel through the entire circuit, while in a refrigerator with a double cooling circuit the fluid travels only through the refrigerator and not through the freezer. And it is not the only advantage. These refrigerators with double cold circuit are especially interesting so that food odors do not mix placed in the refrigerator and freezer. This also means that the moisture collected from the refrigerator does not reach the freezer, thus obtaining a drier area and better preserved food. And, be careful, this is important, since with a double circuit the humidity stays where it should be, making the tomatoes stay fresh for twice as long. Of course, just because a refrigerator is No Frost does not mean it is good. Almost all modern refrigerators are No Frost, but the single circuit one is a ‘Total No Frost’ that dehydrates the food. The double circuit ones are a ‘Smart No Frost’. Furthermore, the fact that a refrigerator has a double circuit means that, in most cases, it can be attractive for when we go on vacation. And this is because you can turn off only the refrigerator part while leaving the freezer part on. And this represents savings. The good and the bad of both options, face to face Refrigerator (traditional) Refrigerator (double cold circuit) THE GOOD 🟢 They are more economical and require less maintenance in the long term. It maintains higher humidity in the refrigerator, does not mix odors and is usually more energy efficient. THE BAD 🔴 Odors can mix, food can dry out, and it is more difficult to maintain constant humidity and temperature. They are more expensive and usually require more maintenance in the long term. Ideal for: Tight budgets and for families of one or two people. Prevent odors from mixing and for families of three or more people. In summary: 👉 Choose a traditional refrigerator if: You are a person who lives alone or in a family of two people or you are looking for a refrigerator that does not increase too much in price. 👉 Choose a refrigerator with a double cold circuit: You are looking for a better flavor in food or you live at home with two or more people. Recommended models Traditional refrigerator: Hisense RB372N4AWE The Hisense RB372N4AWE is a 292-liter refrigerator with a single cold circuit that is interesting because it has a technology that means that if you leave the yogurt at the bottom it will not freeze or if you have the milk on the door it will not stay warm, the temperature is uniform in every corner. Also It comes with micro perforations to inject cold air into each shelf of the refrigeratorpreserving food better, and with technology Total No Frost to prevent frost from forming in the freezer. In addition, this refrigerator includes a fruit and vegetable drawer that allows you to control the humidity to keep food fresh and comes with a vacation mode so that it operates at a constant temperature of 15ºC, which can save energy. As a curiosity, its door is reversible, so you can choose to open it to the left … Read more

Russia set up a secret network to sell 90 billion in oil. It has fallen due to using the same mail server

by

In the geopolitical chess of international sanctions, where Western governments design complex legislation to suffocate Vladimir Putin’s war machine, sometimes checkmate comes not from a brilliant diplomatic maneuver, but from corporate stinginess. An entire global smuggling network, designed to the millimeter to be invisible to the eyes of Washington and Brussels, has fallen like a house of cards for not wanting to pay separate email bills. A simple saving in computer infrastructure has exposed a monumental flow of black money. a colossal IT blunder (a huge computer error) has brought to light a smuggling network that has moved at least $90 billion worth of Russian oil. As revealed by extensive research of the Finance Timesthis plot is mainly responsible for financing the Kremlin in its war against Ukraine. The British media has identified a network of 48 companies which, on paper, operated completely independently from different physical addresses. However, in practice, they acted in unison to disguise the origin of the crude oil, especially that of Rosneft, the Russian state-controlled oil company. The need to hide these exports became life or death for the Kremlin in October 2025, when the United States imposed direct sanctions to Rosneft and Lukoil. From that moment on, a previously unknown company called Redwood Global Supply was suddenly crowned as the largest exporter of Russian crude oil in the world. This firm, along with the rest of the network, is linked to a group of businessmen of Azerbaijani origin with privileged access to the leadership of Rosneft, led by figures such as Tahir Garayev and Etibar Eyyub. The independent Russian media The Moscow Times has been echoed of this discovery, highlighting a devastating fact: in November 2024, more than 80% of Rosneft’s maritime exports They moved through this network. Sergey Vakulenko, former head of strategy at Gazprom Neft and current researcher at the Carnegie Center, explained to this medium that using fifty shell companies is “an old trick from the 90s” to evade taxes, but he confesses his surprise at the fact that a single network has become so immensely crucial for a giant like Rosneft. The triumph of shadow intermediaries The existence of this network means, quite simply, that the Western sanctions system is full of holes and that Russia has managed to industrialize evasion. According to the investigationthe success of this $90 billion network was based on strict separation of roles to erase the money trail. The network used a group of shell companies exclusively to buy crude oil shipments in Russia, and another group of companies, totally different on paper, to sell them in key markets such as India or China. In this way, the initial buyer and the final seller almost never coincided in customs documents. Furthermore, in most cases, the crude oil was labeled under generic names such as “export mix”, which destroyed any possibility of tracing its origin or checking whether the price cap imposed by the G7 was being respected. As we already explained at the time in Xatakathis modus operandi It is not new and it relies on an architecture of evasion that has been brewing for years in places like the United Arab Emirates. Something very similar happened with the case of Christopher Eppinger, a young trader German that perfectly illustrates how this underworld works. As we detailed in our report, while Europe boasted of energy sovereignty, an army of new intermediaries moved to Dubai—a jurisdiction that does not apply sanctions to Moscow—to make gold. The network now discovered by the British media uses exactly the same tools that we already analyzed: the express creation of opaque companies, the use of the “ghost fleet” (aging ships that turn off their transponders when approaching to load Russian crude oil) and transfers of oil on the high seas to mix it and falsify its origin. The only difference is that the Rosneft network uncovered by the FT was operating on an unprecedented industrial scale… Until they made a rookie mistake on the internet. The rookie mistake This entire sophisticated international network collapsed due to an absurd detail that borders on comedy. He Finance Times discovered that these 48 multi-billion dollar companies shared a single private server for their emails: mx.phoenixtrading.ltd By pulling this digital thread, the journalists of the FT they managed to identify 442 web domains who shared administrative functions of back office on that same server. The next step was pure data mining: they compared the names of those domains with the customs records of Russia and India. Thus, they discovered that the domain foxton-fzco.com It corresponded to Foxton FZCO (based in Dubai), buyer of $5.6 billion in oil; and? advanalliance.ltd It was Advan Alliance, which sold 1.5 billion to India. The desire to create and destroy companies quickly to mislead sanctioners—according to The Moscow Timesthe average lifespan of these signatures is only six months—led the network to centralize your IT infrastructure to reduce costs. A saving that has cost them their anonymity. The show must go on In the short term, the strategy of those involved is denial and adaptation. How to collect Finance Timesboth Tahir Garayev and Etibar Eyyub have categorically denied their involvement in sanctions evasion, calling the accusations “baseless” (curiously, Eyyub sent his denial from an email address hosted on the compromised server). The original company that founded the network, Coral Energy (now 2Rivers), has also disengaged from operations. However, behind the scenes, the machinery is already looking for new avenues. A senior Russian energy executive, speaking on condition of anonymity, summed up the situation in the investigation starkly: “It creates additional costs and inconveniences. But at the end of the day, the show must go on.” The United Kingdom has already reacted to the investigation of the British media, sanctioning nearly 300 entities linked to this “dark web”, blocking Russian ships and banks. The fall of this immense $90 billion network shows that, in the 21st century, bank secrecy and flags of convenience are useless if the system administrator decides … Read more

The US has had a grain for “Iran”. The United Kingdom does not allow its bombers to enter a secret island that is key to the attack

by

Since the Cold War, many of the great powers have understood that modern wars do not begin when the first plane takes off, but when secures access to the bases from which it will take off. Sometimes the deciding factor is not so much firepower, but the key that opens or closes a key clue at the exact location on the map. That is happening right now on a lost atoll. A problem with name and surname. The United States has had a major problem for “the Iran thing” and it is not in Tehran, but in the Indian Ocean. United Kingdom refuses to authorize the use of Diego García Island and the RAF Fairford base for a possible air campaign against the Islamic Republic, alleging that it could violate international law if it is a preventive attack. Without that permission, Washington loses two key platforms to project its long-range air power, just when the president has given an ultimatum to Iran and has hinted that in a matter of days he could decide between an agreement or a military operation. The secret island that sustains long wars. It we count some time ago. Located halfway between the east coast of Africa and the west coast of Indonesia, The island was part of the Chagos Archipelago. During the 18th century, it was colonized by the French as an agricultural settlement. So they took the Chagossians, descendants of slaves from Africa and India, to the islands to work on growing coconut trees for the production of copra (dried coconut meat). Over time, the locals developed their own culture and dialect, known as Chagossian Creole. By 1814, after Napoleon’s defeat, The island came under British control as part of the Treaty of Parisintegrating into the colony of Mauritius. Throughout the 19th century, life on the island continued with a small population dedicated to agriculture and fishing, but things were about to change with the beginning of the new century. The agreement. During the Cold War, The United States and the United Kingdom sealed an agreement. Both nations saw the island as a strategic location for a secret military base in the Indian Ocean. In 1965, the British separated the Chagos Islands from Mauritius, thus forming the British Indian Ocean Territory (BIOT), which also includes the other 57 islands of the Chagos Archipelago. By 1966, he signed a secret agreement with the United States, allowing the construction of the “secret” military base. Key node. Since then, Diego García is anything but any base, because he is one of the more strategic enclaves of the Pentagon in the Indian Ocean. Its central runway, its port capable of hosting nuclear submarines and its logistics infrastructure allow strategic bombers to be deployed, maintained and rearmed in sustained cycles. Without going too far, last year it already served as a pressure platform when several B-2s arrived in a clear message to Iran, and precisely that type of deployment is what is now conspicuous by its absence. That there are no visible bomber movements towards the island reinforces the idea that the british veto is conditioning military planning. Without bases there are no prolonged campaigns. The geographical difference is abysmal and explains the tension. From Diego García to Iran there are around 2,300 kilometers, from the United States more than 6,000. That distance sets the pace of departuresthe wear and tear of the crews and the intensity of the offensive. For a one-night operation you can fly round trip from Missouri, as was the case in previous attacks, but for a campaign a week or more against nuclear installations, military commands and missile launchers, advanced bases are needed that allow constant sorties to be generated. In other words, without access to the island and Fairford, the role of the B-2, B-1 or B-52 is greatly reduced and the plan loses volume. A clash between allies. The disagreement is not only technical, it is deeply political. London maintains that supporting an attack could implicate it legally if it knows the circumstances of an action considered unlawful, and the prime minister has marked distances with the White House. Washington, for its part, has responded hardening the tone and linking the refusal to the dispute over the future of Diego García within the Chagos Archipelago, whose status and possible transfer to Mauritius have opened a diplomatic rift. Thus, what began as a legal debate has led to a strategic struggle between historical allies. The war that is amplified without the key piece. Meanwhile, the United States continues to accumulate fighters, electronic warfare aircraft and resuppliers in the region, preparing the board as if the military option was still alive and imminent. It turns out that the heart of a prolonged air campaign is not the F-22s in transit, but those strategic bombers operating from a secure and nearby base. Yes UK maintains the vetoWashington will have more distant and less efficient alternatives, which would force the scope and intensity of the blow to be redesigned. In short, in full escalation with Iranthe piece that could do it all more simple For Washington it is precisely the one that blocks the movement today.

Sparkling water has a “secret” to losing weight. And it has nothing to do with its nutritional properties.

by

Sparkling water is one of those ‘rare’ options on the drinks menu that few people consume in our environment, but little by little it is gaining popularity. prominence in the dietary field. All thanks to a recent scientific publication that pointed to its benefits in order to lose weight with its consumption, although there is quite a bit of fine print under this premise. The study. The epicenter of this new wave of enthusiasm is placed in a study published in BMJ Nutrition where a fascinating hypothesis is raised: carbon dioxide dissolved in water could increase the glycolysis in the organism. A process that basically does is ‘break’ the sugar we have in our cells to obtain energy. In this way, we would be reducing one of the components that gives rise to the ‘hated’ fat that we want to avoid. As? Drinking sparkling water and having this happen is not something very ‘normal’ a priori. Science suggests that, when consuming carbonated water, the CO₂ that gives rise to those bubbles that we see on its surface passes into the bloodstream, where it could stimulate our red blood cells so that they use more glucose and therefore, it does not accumulate as fat. On paper, it sounds like music to the ears of anyone looking to lose weight: drinking water to burn off sugar. There is small print. The study itself is a brief report and the scientific community she has been quick to qualify it: Even if the mechanism exists, the isolated effect is too small to produce “miraculous” weight loss just by drinking water. In this way, we are not facing a great ‘fat burner’, but rather a metabolic curiosity that will hardly be noticed on the scale if it is not accompanied by other changes. The real trick. If sparkling water doesn’t magically “burn” calories, why do many nutritionists insist that it helps with weight control? The answer lies not in metabolism, but in fluid mechanics and satiety. This is not something new, but studies from 2008 already showed that carbonated drinks had a direct impact on the stomach. The first effect focuses on the distention of the stomach, since the gas takes up volume. Thus, when drinking sparkling water, there is greater distension of the ‘upper’ part of the stomach compared to normal water. This makes we get full faster and we don’t want to continue eating. There is more. But beyond filling us up faster, this distension sends satiety signals to the brain through the vagus nerve. That is why the bubbles “trick” the stomach, making it believe that it is fuller than it really is. In this way, the brain interprets that it is full and inhibits our desire to continue eating. thanks to chemical inhibition. Japanese investigations on oral stimulation with CO₂ suggest that this feeling of fullness can reduce subsequent food intake, although the effect is modest and short-term. The substitution factor. The strongest argument for sparkling water has nothing to do with CO₂ or gastric motility, but rather behavior. This is precisely what I was aiming for. a meta-analysis by McGlynn which reviewed what happens when we replace sugary drinks with calorie-free options. The results in this case are quite clear: replacing cola or packaged juice with water (with or without carbonation) reduces weight, BMI and body fat. And this is where sparkling water shines as a replacement tool, since for many people accustomed to the sensory “aggressiveness” of a carbonated soft drink, flat water is boring. And its impact. Sparkling water offers that oral stimulation, with the beloved sting of bubbles, without the “toll” of empty calories. If carbonated water helps you quit sugary sodas, that is the relevant clinical impact, not the fact that carbonated water speeds up the burning of sugars we have previously consumed. It’s not for everyone. Although hydration guides indicate that sparkling water hydrates exactly the same as regular water, it is not for everyone. That same mechanism that helps satiety (gastric distension) is the number one enemy for certain clinical profiles, such as for those who have gastroesophageal reflux or irritable bowel syndrome. Here, increasing the pressure of the digestive system can aggravate these diseases.

Spain’s secret weapon in the Olympic Games is a skater dressed as a Minion. Universal almost prevented it

by

Tomàs-Llorenç Guarino Sabaté had been preparing for months for the most important moment of his sporting career. The 26-year-old Catalan skater, six-time Spanish champion, was clear about how he wanted to make his debut in the Olympic Games: dressed as a Minion, on the ice of Milan-Cortina 2026performing a medley of songs from the Universal Pictures animated saga. He had used that program throughout the season in international competitions, with the characteristic costume of blue jumpsuit and yellow t-shirt. I thought I had all the permits in order. Drama at Universal. On February 3, just four days before the opening ceremony of the Games, Guarino received devastating news: Universal Pictures was denying him permission to use the Minions’ music and costume in the Olympic event. “I was informed that I no longer have permission, due to copyright issues,” the skater explained in a statement published by the Royal Spanish Ice Sports Federation. Their competition was scheduled for Tuesday, February 11. Changing programs at that point seemed impossible. Permits? What permissions? In August 2024, before starting the season, he had processed the necessary permits through ClicknClearthe official system that the International Skating Union (ISU) makes available to athletes to manage music rights. His intervention included four pieces: Universal Pictures’ characteristic fanfare in the Minions version, ‘Freedom’ by Pharrell Williams (which appears in ‘Despicable Me’), and two other compositions related to the franchise. Negotiations begin. The week before the Games, Universal Studios requested additional information about the music and costumes that Guarino had been using for months. A race against time then began: the skater and his team had to negotiate simultaneously with Universal Pictures, Pharrell Williams, Sony Music and Juan Alcaraz, each owner of different rights of the songs. But as the news spread on social media, the massive support for Guarino convinced Universal to reconsider its position. All good. The skater quickly got approval for two of the songs, and got permission for a third by contacting the composer, also Spanish, directly. The fourth and final piece, Pharrell’s, was resolved at the last moment. On Friday, February 7, just two hours before the figure skating competition at the Games began with the team event, final confirmation came. The Royal Spanish Ice Sports Federation (RFEDH) announced that Guarino had obtained all the necessary licensesand managed to participate as planned last night. The laws. Guarino’s case is not an isolated incident. For decades, the International Skating Union (ISU) strictly prohibited the use of music with lyrics in competitions. Skaters could only choose instrumental pieces, usually classical music, that were in the public domain and did not raise copyright conflicts. In 2014the ISU decided to allow vocal music to attract a younger audience and modernize the image of the sport. The first time was in PyeongChang 2018. More cases. This artistic opening brought unforeseen consequences: skaters began to use copyrighted music, and artists began to claim compensation for its use. Alexa Knierim and Brandon Frazier used a version of ‘House of the Rising Sun’ performed by the duo Heavy Young Heathens in Beijing 2022, who sued them. This year, Russian Petr Gumennik They denied permission to use the music from the soundtrack of ‘The Perfume’. Belgian Loena Hendrickx changed one Celine Dion song for another at the last minute due to legal complications. Canadian artist CLANN expressed his displeasure upon discovering that the American Amber Glenn had used one of her songs, even though she had won the team gold medal with it. Mea Culpa. ISU President Jae Youl Kim has openly acknowledged the extent of the problem during these Games. The organization continues to seek solutions, but the complexity of the music rights ecosystem (involving songwriters, performers, production companies, record labels and distribution platforms) makes any licensing system vulnerable to errors or misunderstandings. The 2014 decision to modernize the sport by allowing vocal music was intended to revitalize it and bring it closer to new audiences, but has generated an unforeseen side effect.

Anthropic wanted to secretly scan and then destroy millions of books to train its AI. It hasn’t been so secret

by

A language model for AI needs input if it is to be trained to be more accurate and effective. The issue is how the information is obtained and whether there is an ethical way to do it that is profitable for the technology company in power. There is no doubt that the preferred option for companies has been to use all possible physical and digital content without anyone’s permission. There is also evidence. A judicial leak reveals that Anthropic invested tens of millions of dollars in acquiring and digitizing literary works without permission from the authors. According to account Washington Post, the project, internally called “Panama”, was part of a frenetic race among big technology companies to accumulate massive data to train their artificial intelligence models. How it all started. The Panama Project was launched by Anthropic in early 2024. According to internal documents revealed per the Washington Post, the goal was to “destructively scan every book in the world.” Furthermore, these documents also explicitly state that the company did not want anyone to know that they were working on it. In about a year, the company spent tens of millions of dollars buying millions of books, cutting their spines with hydraulic machines and scanning their pages to feed the AI ​​models that power Claudeits star chatbot. According to the media, the books, once digitized, ended up being recycled. Because has come to light. The details of the project have been revealed in a lawsuit for infringement of rights copyright filed by literary authors against Anthropic. Although the company agreed to pay $1.5 billion to close the case in August 2025, a district judge decided to make more than 4,000 pages of internal documents public last week, exposing the entire operation. They are not the only ones. Court documents reveal that other technology companies such as Meta, Google and OpenAI had also participated in this race to obtain massive information to train their models. According to revealed According to the documents, an Anthropic co-founder theorized in January 2023 that training AI models with books could teach them “how to write well” instead of imitating “low-quality internet slang.” On the other hand, an internal Meta email from 2024 described access to a digital library of books as “essential” to be competitive with rivals in the race to dominate AI. However, the documents revealed by the media also show how Meta employees expressed concern on several occasions about the legality of downloading millions of books without permission. An internal email from December 2023 indicates that the practice had been approved after being “escalated to MZ,” apparently referring to CEO Mark Zuckerberg. According to court records to which the media has had access, the companies did not consider it “practical” to obtain direct permission from publishers and authors. Instead, they found ways to mass-acquire books without the writers’ knowledge, including downloading unauthorized copies from third-party sites. Chat logs from April 2024 show an employee asking why they were using servers rented from Amazon to download torrents instead of Facebook’s own. The answer: “Avoid the risk of tracing” the activity back to the company. Data torrent. The documents to which the Washington Post has had access also they test that Ben Mann, co-founder of Anthropic, personally downloaded over 11 days in June 2021 a collection of books from LibGen, a gigantic library of copyrighted content. The outlet further revealed that, a year later, in July 2022, Mann celebrated the launch of the ‘Pirate Library Mirror’ website, which boasts a massive database of books and openly claims to violate copyright laws. “Just in time!!!” Mann wrote to other Anthropic employees, according to the outlet. Anthropic stated in legal documents that it never trained a revenue-generating business model using LibGen data nor did it use Pirate Library Mirror to train any full model. Anthropic’s legal solution. According to point the medium in its article, faced with the legal risk, Anthropic changed its strategy. The company hired Tom Turvey, a Silicon Valley veteran who had helped create the project Google Books two decades earlier. Under his direction, Anthropic considered purchasing books from libraries or secondhand bookstores, including New York’s iconic Strand bookstore. The company ultimately ended up buying millions of books and stacking them in a giant warehouse, often in batches of tens of thousands, according to court filings. The Washington Post assures In addition, the company worked with used book sellers in the United Kingdom. A project proposal mentions that Anthropic sought to “convert between 500,000 and two million books in a six-month period.” What the law says. Most legal cases against AI companies are still ongoing, but the media mention two court rulings that have considered that the use of books to train AI models without permission from the author or publisher may be legal under the “fair use” doctrine of copyright. In June 2025, District Judge William Alsup determined that Anthropic had the right to use books to train AI models because they process them in a “transformative” way. He compared the process to teachers “teaching schoolchildren to write well.” That same month, Judge Vince Chhabria ruled in the Meta case that the authors had not shown that the company’s AI models could harm the sales of their books. In the Anthropic case, the physical book scanning project was considered legal, but the judge determined that the company may have infringed copyright by downloading millions of books without authorization before launching Project Panama. The final agreement. Instead of facing a trial, Anthropic agreed to pay $1.5 billion to publishers and authors without admitting guilt. According to point According to the media, authors whose books were downloaded can claim their share of the settlement, estimated at about $3,000 per title.
