We knew that coffee was good for health, but now we have discovered that it is a great ally of our microbiota

by

For years, coffee has not been too well considered. It depends on the place and the historical momentbut the culprit was not so much coffee itself … as caffeine. Although the evidence has managed to deny them, there is still A lot of myths about caffeine and its effects. But something that is also making clear research is beneficial effect of coffee on the body. It depends on the type of tan, of course. And one of the studies More recent links coffee with the intestinal microbiota. Directly, it favors the Bacteria growth in our body. And it is something that fulfills a vital function. The community Microbial of coffee. As we say, different studies on coffee allow you to have discovered your beneficial effects on cardiovascular diseasesthe diabetes or your Effect on the kidneys. In parallel, a relationship between coffee intake had been observed with the increase of certain intestinal bacteria, but the studies were on a small scale. Now, in Nature Microbiology he has Posted a study in which the genomic sequence of the intestinal microorganisms of more than 22,000 people in the United Kingdom and the United States was investigated. They have discovered that coffee drinkers had a different microbiota, with intestinal bacteria such as Lawsonibacter asaccharolyticus Eight times more abundant in the microbiota of coffee drinkers than in those who do not ingest this food. And what does that imply. It is not limited to that bacteria, since increases in irmicutes, actinobacteria, actinobacteria were also observed, PREVETELLA, Faecalibacterium and Bifidobacterium, All of them linked to beneficial metabolic effects, such as greater production of short chain fatty acids. What this means is that, thanks to its polyphenols and the soluble fiber it contains, coffee produces some Prebiotic effects that have a direct influence on beneficial bacterial growth. Before I said that it is something that fulfills a vital function, and in this case it is not an exaggeration. Intestinal microbiome bacteria They fulfill functions such as facilitating digestion, strengthening the immune system, regulating inflammation or protecting against pathogens and diseases. Very direct effects of this includes the production of vitamins and enzymes that are not obtained from food, facilitating Digestion of compounds as fiber and starch or Immune system regulation to distinguish between harmful and benign organisms. Four cups. Tim Spector is one of the experts who has supervised the article and, as my colleagues from Straight to the palatethe amount of optimal coffee would be between two and four cups a day. It all depends on the organism of each one and tolerance, but something interesting is that we not only obtain those benefits for the microbiota, but also a a large amount of fiber. Specifically, 1.5 grams of fiber for each cup of Filtrated coffee (There are many ways to prepare it, but filtered or infused is one of those that allows to extract more nutrients), and it is an amount similar to what would be obtained when eating a tangerine And the caffeine, what. And this of the tolerance that each one has to coffee is important because there is a “Limit” in the amount of caffeine That we can take up to be in the healthy segment, but it depends a lot on each person. The good thing is that these positive effects on microbiota have been reported both in the ‘normal’ coffee and in the decaffeinated. If milk is addedIn addition, the amount of polyphenols may slightly decrease, but the balance is still positive. What should not be added is sugarsince there we would be doing more bad than good. But if decaffeinated coffee is consumed, you should have an eye on how the process has been performed. Not all decaffeinated coffees are the same because there are several ways to eliminate (which is not completely eliminated, but is considerably reduced) caffeine, and Not all are equally healthy. To the point that some methods They are under the radar of organizations such as the US FDA. Image | Justin Bhalla In Xataka | There are more and more studies that link coffee with living more. And it is very easy to put the leg when preparing that ‘philosopher’ coffee

We knew that the Dart mission changed Dimorphos’ trajectory. What we did not know is that its form also changed

by

At the end of September 2022, the Dart mission (Double Asteroid Redirection Test) It made historyInterestingly, stamping against an asteroid. The milestone was not on the impact itself but on achieving with him slightly divert the trajectory of an asteroid, Dimorphos. The expected and the unexpected. In the almost three years since then, we have been learning New details on the effects of Dart’s impact on Asteroid Dimorphos. Now we know, for example, that Dart not only managed to divert the orbital trajectory of the space rock; He also achieved with his impact to make the asteroid orbit deform significantly What happened. The asteroid, explained the team, initially had an oblate form, that is, flattened in the poles, such as the earth, “the shape of a hamburger.” After the impact, Dimorphos became a rather prolata, elongated in the poles, like a rugby ball. “For the most part, our predictions pre-impact on how Dart would change the way Didymos and her moon (Dimorphos) move in space were correct,” ” explained in a press release Derek Richardson, who led the analysis of the effects of the probe. “But there are some unexpected discoveries that help provide a better image on how asteroids and other small bodies are formed and evolved over time.” Tumbos. According to the team that analyzed these orbital changes, the impact would have made dimorphs pass from a state of equilibrium with its main asteroid Didymos similar to that of our moon with the earth, to an irregular one. That is, dimorphs always gave the same face to Didymos, at least Until Dart arrived. Now the system is out of its alignment, Richardson pointed out. This implies that it can stagger changing orientation, even ending up “tumbos”, rotating chaotically and unpredictable. Asteroid formation. Thanks to studies such as the one conducted by Richardson and the team, we can access new clues about the formation of asteroids. As explained by the team, the impact released small rocks that remained in the orbit of the asteroid system. These contributed to altering the orbital movement in the system, but these changes in the gravitational balance do not seem to have altered the form of didymos. This implies, the team added, that the main asteroid of the system was rigid and firm enough to maintain its form after the formation of its moon dimorphs. The details of the work were Published in an article In the magazine Planetary Science Journal. Hera’s turn. The scientific community now has new eyes on the Didymos system, those of Herathe mission of the European Space Agency (ESA) aimed at monitoring the system and collect new data In situ. If everything continues as planned, Hera will begin in October a trip that will lead her to reach the double asteroid towards the end of 2026. The data compiled by Hera They will allow an even more exhaustive analysis of the impact of the Dart mission. This in turn will be what gives us key clues that allow us to plan missions that protect our planet from the asteroid shock.

We knew that many use Starbucks as an office. In South Korea they lead to the printer, and the chain has said enough

by

Enter a Starbucks store and meet several people installed with your laptop It is no novelty. The spacious tables, the plugs available, the air conditioning and, of course, the coffee, make these premises a habitual shelter for students and remote workers. A printer on the table. A cardboard separator to isolate itself from the world. A strip to plug laptop, mobile and tablet at the same time. All this has been seen – and is still seen – in some South Korea Starbucks. The phenomenon has shot, and therefore, the chain has decided to intervene. New standards in South Korea. The new regulation is clear: no printers, multi -mitoms or accessories that convert the premises into a portable office. This is what The Korea Herald collects itwhich adds that it is also not allowed to occupy several chairs or leave belongings for hours to “reserve” table. The original poster (left), the translation of Google Lens (right) From this week, employees have instructions to warn those who fail these guidelines. The measure communicates with a poster that already decorates dozens of stores in the country. And although the message is illustrated with a smiling bear, the background has nothing tender. What does it mean to be a 카공족. In South Korea, 카공족 It is the name that receives “the tribe that studies in coffee.” The term combines the words 카페 (cafeteria) and 공부 (study), and is used to describe those who spend hours working or reviewing notes in premises such as Starbucks. What began as a practical and punctual solution has become such a widespread custom that now raises a dilemma: is it a legitimate use of space or silent abuse of the common environment? The social reaction. The Donga Ilbo medium collects The testimony of Professor Seo Kyung-Duk, from the Sungshin Women’s University, who shared the image of the computer equipment with the cardboard separator: “It looks like a private office.” SEgún explainedeven the foreigner who accompanied him was bewildered: “How can anyone mark their territory in a public place like a cafeteria?” He asked, surprised. Some of the images that account for 카공족 in South Korea The author of the photo explained that this person did not return in all the time he remained in the store: “I spent three hours there and did not return once,” he said. Meanwhile, Asia Economy echoed some Of the most repeated reactions among users: “There is not even room to have coffee because of the 카공족,” said a person. Another ironized: “They leave their things and they will eat … is this a ‘Study Café’ or what?” Why have Starbucks Korea acted now? Starbucks has not acted in whim. According to the company, what is at stake is the collective experience. When a large table is occupied for hours by a single person, or when a client is absent leaving their objects as a reservation, the balance between those who enter, consume and leave, and those who turn the place into a personal office. There is also a commercial logic. Maintaining rotation is key in a business where each table counts. If someone occupies a seat for four hours with a single coffee, the impact is not anecdotal. If not, tell the owners of coffees in Barcelona, They are applying their own formula “anti occupies terraces”.

We knew that North Korea has been infiltrating workers in companies in the West. Now we know how they do

by

North Korea has been infiltrating teleworkors with false identities in United States companies. After that country became more hostile, the actor’s attention turned to Europe. According to the FBI, the Department of Justice and Googlewhat these employees pursue is to get income to finance the North Korea Nuclear Program. He modus operandi It was a great unknown. Until now. A framework without any improvisation. A cybersecurity researcher who responds to the name of Sttyk It was made with a database that has shown the environment Wired. The files include, according to Sttyk, “dozens of data gigabytes” and “thousands of emails.” From this information an organized workers’ structure is extracted in twelve groups, which in turn have approximately other twelve members. They respond to a general “master boss.” Organization in spreadsheets. The group works using the Slack communication tool, Google, Github and spreadsheets accounts. In the latter, an exhaustive follow -up of the works and the progress of the objectives, both economic and strategic, is made. They even collect the needs of specific jobs (required programming languages) of the companies to attack and their locations, with a record of whether there have been contact with the companies or progress of the process. How they get work. A few days ago, the BBC collected Jin-Su’s testimonya false North Korean teleworking that managed to defect. He said that most of the time of his work focused on acquiring fraudulent identities to request work. He went through Chinese, but aware that he needed Western identities, more attractive to the labor market, he got identities of people from Hungary, Türkiye or the United Kingdom. From there, the most involved workers in the process of getting work are the ones who most dominate English, although the fact that communications with technology companies are done by platforms such as Slack helps a lot. Also that many interviews are not made face to face, although that can be reversed with the proliferation of interviews made with artificial intelligence. Researchers have found identical curriculum among the suspects of being false workers. What jobs do they point to. We knew that false teleworkors were looking for employment in technology companies. The filtration is confirmed and limited to the areas: artificial intelligence, blockchain, Bots development, web development and mobile apps and desktop, CMS development, etc. The question of income. Jin-Su said that several works between the United States and Europe, earned about $ 5,000 per month. From what I entered, I had to pay 85% to North Korea, and even so, he said “it is much better than when we were in North Korea.” According to a United Nations report in March 2024, workers manage to generate between 250 and 600 million euros per year for their country of origin. The money they retain has a lot of value when they return to their country (many work from Russia or China, where they have more freedom), so the reasons for dropout lose weight. In parallel to this group of teleworkors operate the hackers that They steal cryptocurrencies To pass at the hands of the regime. Only in a blow in March this year they got 1,500 million, but in December 2024 they accumulated Other 1.3 billion in 47 blows. Working conditions that scare. The filtration presents a scenario that, although better than the one in North Korea, is nothing flattering for the workers involved in the plot. According to a Slack recording, the boss’s account stated in a message that “everyone should work more than at least 14 hours a day.” Although it sounds a lot, it does not perform from the model of some Silicon Valley companies or of the Elon Musk vision and its 120 hours per week.

We knew that living near the sea made us “win” years of life. What we did not know is that it was literally

by

We have known for a long time to approach nature has benefits on our health. Beyond avoiding the contamination of our cities, approaching the natural environments around us can improve our psychological well -being, perhaps even inciting a more active life. Little by little, we are also observing that something similar happens if we change the mountain for the sea. More sea, more life. A study has observed a correlation between residing in coastal areas and greater longevity. The analysis It provides new tests of the link between the bodies of water and the health and well -being of the people. Of course, the relationship between “blue spaces” and health is a bit more complex than it might seem. 50 kilometers. The study observed that the benefits of living near the ocean improved the quality of life of the people who lived in a strip of about 50 kilometers of the coast. Inside, however, they observed a very different trend: the people who resided in the vicinity of water bodies of a certain size (about 10 km² on surface) tended to hope for short life. “Globally, residents of the coast are expected to live one year or more above the average of 79 years, and those who lived in more urban areas near rivers and interior lakes were more likely to die around 78 approximately. The residents of the coast probably lived longer due to a variety of interconnected factors,” stood out in a press release Jianyong “Jamie” Wu, member of the study responsible for the study. 66,000 census areas. The study was conducted in the United States, where the team analyzed 66,263 census areas, studying life expectancy and its relationship not only with the proximity of water bodies, also with socio -economic and demographic factors to control the results. The details of the study can be consulted In an article Posted in the magazine Environmental Research. Looking for the cause. The team indicates different factors that could mediate this relationship, such as softer temperatures, better air quality, greater number of opportunities for recreational activities, better transport, less vulnerability to droughts, or rent. These factors could explain why residing near the coast is associated with greater life expectancy, in contrast to people who live near interiors. “Contamination, poverty, lack of opportunities to be physically active and a greater risk of flooding are the main triggers of these differences,” Yanni Cao indicatedCo -author of the study. Correlation or cause? It fits remember that the existence of a correlation does not always imply the existence of a direct (not even indirect) relationship of causality. For example, if income is the determining factor, this causal relationship could have different forms. A possible way would start from the fact that coastal areas They would be more expensiveso they would attract people with more rent, being income, a factor we know affects our life expectancy. Another possible way would be in the fact that the coastal areas generate greater income by offering more job opportunities, and these income again would be the determining factor in longevity. In both cases the mediating factor is the same, but the causal relationship does not. In Xataka | Why is it more hot in cities than in the field: the urban heat island effect Image | Emiliano Arano

No one knew what happened for 12 years in a Volkswagen ranch in the Brazilian jungle. Until a priest made a call

by

During the darkest years of the Brazilian military dictatorshipwhen the regime promoted at all costs the colonization of the Amazon under the flag of development, one of the largest multinationals on the planet expanded its automobile empire in Latin America. At the same time, he directed an ambitious livestock project deep in the jungle. That multinational was Volkswagen, and in 2019 a priest He revealed a tragedy. Awakening from a forgotten memory. The story was told this week The Washington Post In an extensive report. When in 2019 the priest and academic Ricardo Rezende Figueira read that Volkswagen Brazil was willing to Recognize and repair His complicity with the Brazilian military dictatorship for the political persecution of workers in factories, felt something missing. There was no mention of Vale do rio crystallinethe huge livestock farm of the company in the Amazonian jungle. That land of more than 140,000 hectares, where hundreds of workers were recruited under deceptionisolated, indebted, mistreated, tortured and forced to work in degrading conditions for more than a decade, it seemed to have been History erased. There are evidence. But Rezende, who in the 80s documented those abuses as part of his work with the Pastoral Commission of the Earthstill It kept the evidence: More than a thousand pages of testimonies, notarial statements, police reports and press clippings accumulated in your personal archive. After reading the news, the priest telephone to prosecutor Rafael Garciaspecialist in slave work at the Ministry of Labor. That call would resurrect one of the darker chapters of corporate advance in the Amazon. A jungle turned into hell. The documents that he rebounded delivered to the authorities offered a devastating radiography. Between 1974 and 1986, in full military dictatorship, Volkswagen Brazil (then the largest automotive in Latin America) promoted a Titanic livestock project With regime support: disassemble the jungle in Pará To raise 100,000 cattle, as part of a corporate ideal that the world not only needed cars, but also meat. To do this hired a subsidiaryVale do rio crystalline SA, whose leaders included the president of Volkswagen Brazil himself, Wolfgang Sauer. The company turned to the sadly famous cats (Informal recruiters) who promised good salaries to poor peasants, advanced money and transferred them in trucks to the jungle’s heart. Images of the Brazilian parliamentary delegation during his visit to the farm in 1983 A prison. Once there, the workers were locked in camps remote, forced to work under threat of armswithout medical attention, drinking contaminated water, exposed to malaria, living under plastics and indebted by food and medicines. Not just that. His movements were constantly monitored by armed inspectors. Thus, trying to escape was to face punishment, the disappearance or death. The file that challenged oblivion. For years, Rezende collected Men’s testimonies They escaped from that hell. The records talked about beatings, broken teeth, bare men in the jungle, bodies thrown in cavernseven workers Burned alive. A young man, Valdeci Alves Fumeiro, story Having spent seven years caught in the hacienda, sewn without anesthesia after a fall and forced to continue working. Volkswagen’s announcement in 1977 in Brazil urged other companies to become “neighbors” of their farm in the Amazon Silence. But despite multiple complaints, intelligence reports and official statements that recognized the existence of slave work on the property, never presented A single position penal. I remembered the post that the structure of complicity between companies, state and repressive force guaranteed impunity for decades. Rezee, however, persisted in his conviction: the file had to survive time, because one day he would return to light. And so it was. The prosecutor Garcia, when reviewing the documents, recognized in them the basis for an unprecedented judicial action. A rebuilt truth. The Prosecutor’s Office initiated a national search to locate the workers mentioned by Rezende. The effort fell to the young researcher Matheus Faustinowho toured remote communities for months until he found 14 of the 69 identified. Some, such as Francisco Rezende de Souza, had been devastated by experience: alcoholism, isolation, inability to reintegrate into life. Others, such as the Batista de Souza brothers, were separated and sold by cats even after Volkswagen will leave the project. One of them, Juldemar, was silent for life. Testimonies When in 2023 The trial began in a Federal Labor Court in Redenção, several of these men testified for the first time. “They sold us”, One said. “We slept under plastics,” I commented another. “Everyone was armed, we had to work.” Rezende also went up to the podium. He recalled the complaints since 1977, Volkswagen’s complicity for omission, and the systematic inaction of the State. What does the company say. For its part, Volkswagen Brazil He has flatly denied The accusations. He alleges that his role was merely the shareholder of a company that subcontracted others, and that at the time It did not detect irregularities. In his judicial writings, he argues that it is the government who must hold recruiters and not hold the company. But prosecutors argue that Volkswagen’s subsidiary It was an integral part of the parent company, and that the abuses were systematic and known. Internal documents They show that Volkswagen even organized visits to deny the complaints, while avoiding allowing inspections in the camps. According to the postthe most cynical statement came from the Swiss director of the ranch, Friedrich Brüggerwho in one Interview in 2017 He blamed the workers of his debt and justified the violence of cats as necessary to maintain order: “The Brazilian is a bad person,” declared. The company in Germany has kept silence. Fight for memory. Today, The judicial casewhich requires compensation for 30 million dollarsmarks the first time that the Brazilian State tries to legally hold A multinational by slavery Modern in the Amazon. But for Rezende, which exceeds 70 years and coordinates a Chair of Human Rights in Rio de Janeiro, it is not just a remuneration justice. It is a battle against oblivion.

We knew that humanoid robots would reach factories. Nvidia has already chosen where and when to start, according to Reuters

by

When did humanoid robots stop being a spectacle to become a tool? Maybe that’s right there. Sources consulted by Reuters They assure that Nvidia and Foxconn are in conversations to display them in a server manufacturing plant of artificial intelligence in Houston. Nvidia has trusted the Taiwanese giant to lift a new server manufacturing plant in Houston, Texas. The objective: produce the GB300its new AI servers based on architecture Blackwellwithin the ambitious plan for relocate part of its production in US territory. As Reuters has advanced, both companies are in conversations to display humanoid robots in this factory. The intention would be that they begin to operate in the First quarter of 2026. If concrete, it will mark a double milestone: it would be the first time that a NVIDIA product is manufactured with the help of these tools, and also the first use of this technology by Foxconn in a production line of AI servers. Houston is not any factory: something new is prepared here For now, the details are scarce. It is not known how many robots will be used, how will they look or what exact functions they will perform. But there are indications. In an internal presentation of May, Foxconn showed how he was training humanoid robots for tasks such as manipulating objects, inserting cables or making basic assemblies, usual activities in the manufacture of servers. Houston’s choice is not accidental. Being a new plant, spaces are being designed with margin to integrate these technologies From the beginningsomething much more complex to achieve in already operational facilities. According to one of the sources consulted, that design would facilitate the incorporation of humanoid robots in the line. NVIDIA GB300 has a rack scale design That Nvidia bet on humanoid robots in its production chain is not just a logistics movement. It is also a declaration of intentions. Until now, no company product had been manufactured with the help of this type of robots. And Foxconn, the largest manufacturer on the commission of the world, had not used them in a production line dedicated to AI servers. The decision, according to what the sources have told Reuters, would mark the beginning of a new stage for both companies. In the case of Foxconn, it would also serve to show the world the advances in robotics who has been developing with Nvidia, although third -party models such as those of China Ubtech have also been tested. For Nvidia, the movement fits with its broader strategy. The company not only designs chips for AI models training: it also offers A development platform Specific for humanoid robots, with visual, motor and cognitive abilities based on their own architectures. In March, Jensen Huang himself He predicted that The generalized use of humanoid robots in industrial environments would come “in less than five years.” They are not alone: ​​Tesla, Mercedes, BMW, China The idea of ​​incorporating humanoid robots into the assembly lines is no longer a rarity. Although its deployment is still limited and experimental, several manufacturers have been testing this technology for some time in controlled environments or in very specific tasks. Among them BMW stands out, that has made trials in American plants. And it is known that Teslawhich has developed its own humanoid robot called OptimusHe has put at least two units to work in a production line. But interest is not limited to the great western brands. China has converted humanoid robotics into a national strategic priority Within its Made in China 2025 plan. Companies like Ubtech – whose model has also been evaluated by Foxconn – are being driven directly by the government with a view to transforming the country’s industrial fabric. Strategic alliances are part of this mission Like Huawei and Ubtech Specified this year. This possible deployment of humanoid robots in Houston does not occur in a vacuum. Is part of a broader movement, driven by political pressure and the strategic need of Relocate production Technological on American soil. In April, Nvidia announced its intention To manufacture AI infrastructure of up to 500,000 million dollars in the US in the next four years, with partners such as TSMC, Wistron and Foxconn itself. For many companies, automating is a matter of survival. The Houston factory, still under construction, is part of that strategy. But producing locally implies facing at least one new problem: the shortage of labor. And that is where automation would come into play. Perhaps not essentially for these factories, but as a test field for possible future expansions. For many companies, automating is no longer a matter of improvement. It is a matter of survival. Thus, more and more local actors are developing humanoid robots designed specifically for the industry. Tesla, Figure, Apptronik or Agility Robotics They are among the companies that have opted for this new generation of machines. Jeff Burnstein, president of the Association for Advancing Automation, summed up axios The new industrial reality: “This is how it competes today”, so “you have to take advantage of the best available tools.” Humanoid robots lived for years with skepticism: beautiful exhibitions, Little useful in practice. Now, that perception is turning. We are faced with a change that aims to be important, but whose real range we will know only over time.

We knew that breakfast nuts and other nuts was positive for our brain. What we didn’t know was to what extent

by

Nuts are a nutritious food and considered especially beneficial for our brain. The tests are accumulating, and the last study on this food gives us new details about its value. A push for the brain. The team responsible for the new study He observed an improvement In brain function among young people who consumed nuts at breakfast. The study gives us new clues when understanding the relationship between the popular dry fruit and cognitive performance. “This study helps reinforce the case of nuts as food for the brain. A handful of nuts with breakfast can give young adults an extra mental when they need to perform the maximum performance. It is especially exciting that such a simple dietary change can make a measurable difference in cognitive performance,” stood out in a press release Claire Williams, co -author of the study. Delayed effect. The team observed that on the occasion they consumed breakfast with nuts, the participants achieved faster reaction times throughout the day. They also observed An improvement in memory, but this did not occur in the early hours after breakfast but later in the day. The details of the study were published In an article In the magazine Food & Function. THEORY AND PRACTICE. Through the EEG, the team observed that changes in the neural activity that suggested that nuts can be more effective in their aid to cognitive performance when we face mental tasks that suppose a challenges. For their part, blood tests showed changes in glucose levels and fatty acids, which could help better performance. Explain what nutrients and what biochemical mechanisms are the protagonists of this connection between nuts, and brain is essential when establishing a causal relationship. The team responsible for the new study suggests that A variety of nutrientsamong them the omega 3 fatty acids, proteins and polyphenols, would be responsible for this cognitive “push”. A study with limitations. The small sample implies a limitation when it comes to extrapolaring the results of the study, however it adds to a growing evidence that indicates that nuts (and other nuts) have the ability to improve our cognitive performance. According to Explain the responsible teamThe new study complements the existing literature focusing on the effects of short -term nut consumption, on the day in which they are consumed. They also point out that more studies will still be necessary to determine the relationship between nut consumption and any improvement in cognitive performance.

In 1963 we discovered a pre -Columbian city hidden in the jungle of Peru. It turns out that we only knew the tip of the iceberg

by

Between the VII and XVI centuries the northeastern Andes of what is today Peru saw a rich civilization that planted the Incas: The Chachapoyasthe “cloud forest people.” There, between 2,000 and 3,000 meters above sea level, its people raised funeral and ceremonial constructions that over the centuries ended up devoured by weeds. One of his greatest legacies is Great Pajaténin the San Martín region. Archaeologists have known him for decades, but when studying it with new techniques, such as Lidar scanthey have been surprised. They knew only a small part of the complex. What they have found is so interesting that the World Monuments Fund (WMF) He already speaks of the greatest archaeological milestone in the region since the 80s. What happened? That Peru has just given a pleasant surprise to historians. Especially those dedicated to the study of pre -Hispanic civilizations. A few days ago the WMF) revealed that a group of researchers have identified and documented more than a hundred archaeological structures in the Great Pajaténone of the most important archaeological deposits of ABISEO RIVER NATIONAL PARKin the Peruvian Amazon. In fact It is also known as “the lost city of the Chachapoya” or “El Dorado del Antisuyo”. Why is it important? For several reasons. The study not only provides information that helps understand the settlement. It also helps us to know better the civilization to which it represents: The Chachapoya (“People of the cloud forest”), a pre -Columbian culture that flourished between The VII and XVI centuries and shone among other issues for its constructions, such as the impressive Kuelap fortressa citadel located at 3,000 meters above sea level in what is now the Luya province; or the Great Pajaténwith its circular stone buildings, decorated terraces, winding paths and platforms. And who were the Chachapoya? An outstanding part of the history of ancient Peru. As Remember the WMFthe civilization flourished between the VII and XVI in the northeastern Andes of what is now Peru, organizing around regional manors. Despite the steep terrain they managed to adapt and demonstrate their ability as architects: they built settlements with characteristic circular, friez and mausoleum constructions. Not just that. They also managed to resist the thrust of the Inca, although they ended up subjected in the fifteenth century. What have they discovered exactly? The Great Pajatén is known For decadesis in an environment cataloged by UNESCO And archaeologists had already been in charge of examining it before. In fact, in the 60s they documented 18 structures and time later, in the 80s, they expanded the list to the 26 elements. Now the experts They have discovered that was just the tip of the iceberg. With the help of new techniques and resources, the expedition led by the WMF has identified more than 100 archaeological structures that give a new dimension to the settlement. So relevant is the finding that the organism speaks of the “first important discovery in the region since the 1980s.” “More than duplicate the number of known archaeological structures”, celebrate. What tells us all about the great Pajatén? A lot. The site It was discovered In 1963 And since then archaeologists consider it “one of the most notable Chachapoya sites that are preserved”, with ceremonial buildings decorated with friezes and stone mosaics that represent human figures. The problem is that experts failed to make an overall image of the Chachapoya complex or its reach. The reason? Much of its architecture was still hidden, covered by the lush vegetation of the Peruvian high jungle. That handicap and the lack of perspective had so far conditioned the image that experts had of the deposit. “Its scale, function and chronology were subject to continuous speculation”, They point out from WMFwhich recalls the “unique and highly fragile ecosystem” that surrounds the settlement, in the Abyseo River Park. To shield it the authorities even restrict tourists’ access. And what conclusions have they taken? At the entrance, researchers have confirmed that the Chachapoya presence in large pajatén can be traced to the fourteenth century. And that at least. There are certain clues that suggest “a significantly earlier occupation.” During their expedition they also detected a nearby network of pre -Hispanic paths that connect the whole with the beach, papayas or slopes, which For the WMF It supports “a broader interpretation of the complex as part of a hierarchical and interconnected territory.” “The team documented an architectural set composed of multiple interconnected sectors. This allows us to understand the great Pajatén in its true magnitude, not as an isolated set, but as part of an articulated network of pre -Hispanic settlements of different periods,” Comment Juan Pablo de la Puente, WMF manager. “This finding radically changes the dimension of the site and raises new questions about the role of Pajatén in the Chachapoya world.” How have you discovered it? If great Pajatén has been known for more than half a century and until now the dense vegetation had prevented archaeologists from deepening their study, the following question is obvious: what has changed? Why have you discovered new constructions now? The answer is simple: experts have resorted to new tools that have allowed them to see through that green mantle without altering the environment or damaging structures. The key is in the Lidar scan aerial and manual, photogrammetry, topographic record and technomorphological analysis. Thanks to them, experts have been able to get up The dense mantle of vegetation to take a look at what is underneath, map everything, study the architectural techniques used in the settlement and how it adapts to its surroundings. “Everything without damaging the delicate landscape or its architectural vestiges”, insist From the International Federation. Have you done anything else? “Thanks to the use of advanced technology, our team was able to collect extraordinary visual and scientific documentation that gives life to the great Pajatén, preserving its delicate environment,” celebrateBénédicte de Montlaur, WMF president. “Although the site remains inaccessible to most people, these tools will allow us to share their meaning.” The … Read more

The search as we knew it is over. Google’s AI Mode no longer delivers results, he talks

by

In recent times, Perplexity has done something that seemed unthinkable: Make Google Search feel old. With its conversational interface, direct answers, linked references and a relentless update rhythm, has shown that a search engine with not only possible, but desirable. It is faster, clearer, more useful. And increasingly popular. Many already have it as FJA tab. Google has taken note. And he has responded. The most important announcement – although somewhat camouflaged – of the I/O 2025 It was not a new model or an ultra intelligent agent. It was this: Ai mode arrives at Search and Gemini. Or in other words: Google has begun to transform its search engine into something that looks a lot like perplexity. For now it is only for users of the United States –argh–, but the movement is clear. When AI Mode activates in the Gemini app, the user stops doing classic style searches and begins to receive direct answers generated by the model, with links to sources, relevant context and capabilities to go beyond: compare, ask for explanations, continue asking. The search engine no longer delivers blue link lists, not even a summary above. Find conversation. In this way, Gemini is not a conversational model. It is an active knowledge engine, A synthesis of LLM, browser and assistantwith the ambition to replace the habit of “google” with that of “asking.” You can search for flights, understand documents, ask for cross opinions or compare articles. And all that, without touching an external page. This is not The results with generative that we saw will arrive in Spain a couple of months ago. This goes much further. That were generative responses about classic results. Ai mode is something else: It is more perplexity, more direct, more useful. And more dangerous for the web ecosystem. Because here is the turn that nobody should overlook. In Perplexity, at least for now, the sources are visible, well prominent, and are central to the experience. In ai mode, on the other hand, ambition seems different: respond so much and so well that the user does not feel the need to leave. A closed, polished, self -sufficient experience. That changes things. Not only for the user, who can stop distinguishing between response and source. Also for the media, creators, forums, specialists. Everything that today feeds Gemini from the web becomes less visible in the process. Knowledge is preserved, but loses authorship On the surface. Perplexity Forced Google to advance. But in doing so, Google has changed certain rules. He has taken what works – the synthesis, natural language, speed – and integrates it into an ecosystem, broader, more fluid, also more opaque. If Perpleplexity was a pioneer in experience, Google now counterattacks with total integration. Therefore, the AI ​​Mode in Gemini is not just a technical novelty. It is a paradigm change in how we look, how we read, how we inform ourselves. The user no longer consults a database. Interact with a system that interprets, selects, synthesizes and responds. Google has caught where the search is going. And has decided to move. But in his style. In Xataka | Google has put a price on the future of AI: $ 250 per month Outstanding image | Google
