Now that the most wanted cartel in Mexico has died, three disturbing possibilities open up. All with the US in the target

For more than four decades, the relationship between Mexico and the United States has been marked by a shared war and asymmetric against drug traffickinga fight that has oscillated between open confrontation, silent cooperation and the reproaches mutual while criminal networks adapted, fragmented and strengthened in the heat of the demand for drugs north of the border and violence to the south. In this permanent pulse, each hit against a boss has not only been an operational successbut also the beginning of a new disturbing phase. The biggest blow in a decade. The death of Nemesio Oseguera Cervantes, known as “El Mencho”undisputed leader of the Jalisco New Generation Cartel, represents the most important blow against organized crime in Mexico since fall of “El Chapo”. It is, not only because of the dejected figure, but because structural weight of the organization he directed, which became one of the most expansive, violent and with the greatest international capacity in the country. We are talking about an organization with presence in dozens of nations and a central role in the trafficking of methamphetamine and fentanyl into the United States. The definitive breakup. From the political side, the operation confirms the breakup with the stage of “hugs, not bullets” and consolidates a strategy based on intelligence, coordination and direct action against criminal leaders. In fact, the administration of Claudia Sheinbaum has multiplied arrests, seizures and deployments on the northern border. The internal message is crystal clear: the State seeks regain the initiative in the face of organizations that took advantage of years of limited containment to expand and professionalize. Immediate response that has paralyzed regions. There is no doubt, in an operation of this caliber, the reaction of the cartel has been lightning and coordinatedwith blockades, vehicle fires, attacks on infrastructure and suspension of activities in several states. Cities like Guadalajara and Puerto Vallarta are experiencing panic scenes that are reminiscent of previous crises in Sinaloa after the capture of other leaders such as that of “El Mayo”. And, as almost always, the deployment of federal forces and the alerts to foreign citizens show a reality most uncomfortable: The group’s operational capacity does not disappear with the death of its leader. The great unknown and a risk. This being the case, and with the natural heir imprisoned in the United States, the replacement of the next great drug trafficker open a fight potential between regional commanders and key operators. They remembered in the New York Times that, if the chain of command is not imposed quickly, it is very possible that internal disputes will begin to arise that fragment or weaken the organization. The Mexican experience shows that these transitions usually translate in prolonged violence and territorial fights that affect entire communities. The first possibility looking at Washington. With this scenario, what happens in the coming weeks can greatly alter the security architecture not only of the United States, but from all over North America opening before him three most disturbing scenarios. First of all, a more than possible internal war due to the succession within the CJNG that destabilizes the organization and multiplies all types of sources of regional violence, generating in turn displacement, migratory pressure and greater disorderly flow of weapons and drugs towards the north of the continent. And the remaining two. Secondly, the equally plausible possibility opens up: that of a rival cartels offensive to dispute territories and the most strategic routes, a situation that could trigger a prolonged national conflict similar to the one that occurred in Sinaloaaffecting logistics chains, investment and, in general, border stability. Finally, the third way is that of rapid consolidation under a new leadershipone that, far from weakening the business, makes it more opaque and decentralized, maintaining or even sophisticating fentanyl trafficking to the United States and beyond, which would force Washington to rethink its cooperation, its political pressure and even the debate on direct interventions, with profound implications for Mexican sovereignty and regional integration. In short, with consequences for the entire North American security architecture. A turning point in relationships. The last thing that we have known of the operation has been that it was carried out by Mexican forces together with US intelligence, all in a context political pressure from the White House and millionaire rewards offered by the DEA, along with the review of commercial and security commitments. Plus: arrives after months of extraditionsconvictions and mass arrests linked to the capo’s entourage, suggesting that the operation has been a sustained strategy and not an isolated hit. Tactical success obviously reinforces cooperation, but it will also very likely raise expectations and scrutiny over actual results. If violence expands or the criminal business adapts and diversifies without losing any capacity, such as it has already happened In the past, the region could enter a highest voltage phase strategic that redefines the way in which both countries manage their border, their trade and their shared security.

AI consumes obscene amounts of energy. Sam Altman compares it to the cost of “training” humans

OpenAI CEO Sam Altman participated in an event organized by The Indian Express. During the interview made some striking statements, but the greatest of all of them was the one he dedicated to talking about what it costs to train an AI model. In fact, he complained about how many of ChatGPT’s energy consumption discussions they are unfair. Training humans also consumes a lot. The interviewer asked Altman about ChatGPT’s energy consumption and Sam Altman took a few seconds to answer the question, and then made a peculiar comparison (my bold): One of the things that is always unfair in this comparison is that it talks about how much energy it takes to train an AI model compared to what it costs a human to perform an inference query. But it also takes a lot of energy to train a human. It takes about 20 years of life and all the food you eat during that time before you become intelligent. And not only that, it took the widespread evolution of the hundred billion people who have lived and learned not to be eaten by predators and to understand science and so on to create you. The fair comparison is if you ask ChatGPT, how much energy does it take once their model is trained to answer that question compared to a human? And AI has probably already caught up in terms of energy efficiency if we measure it that way. A previous Epoch AI study corroborates that energy consumption during inference (when we actually use ChatGPT, for example) is low. Source: Epoch AI. Training is one thing, inference another.. The answer may be controversial, but to a certain extent it is logical: learning, both in the case of humans and AI, takes time and consumes many resources, but that cost is one thing and the cost of inference, of “applying that training”, is another. Once we have learned, it is not too difficult to answer things. This is what Altman is trying to point out here, who recognizes that AI does indeed consume a lot of energy in training, but that it has then become very efficient in the inference phase, when we actually use ChatGPT. The problem is that although Altman has already spoken that in inference consumption is minimal, does not provide evidence of this. The water problem is no longer a problem. He also spoke about the controversial water consumption that was theoretically carried out in large AI data centers. Although he acknowledged that this was a problem when “we used to use evaporative cooling in data centers.” Now, however, “we don’t do that,” he recalled, and made it clear that those accusations that “ChatGPT uses 17 gallons per query, or whatever” is totally false, “totally crazy, it has no connection with reality.” But again, there is still no official data from AI companies in this section. How much does AI really consume? The truth is that at this point we still do not have really clear data on how much the AI ​​consumes both in the training phase and in the inference phase. There are those who have investigated energy and water consumption and have made a mistake. wildly exaggerating the databut for example in the US, where a large number of data centers are concentrated, there is no legislation that forces transparency with those figures. Increasingly more efficient models and data centers. One of the most interesting studies was the one made by Epoch AI in February 2025, and at that time it was also concluded that AI did not actually consume as much as it was said to consume. In fact, it consumed relatively little and the models have only improved in efficiency. Chips and cooling systems have also improved, and although data centers have certainly require enormous amounts of energywe continue blindly in this section.

now many disappear before reaching their destination

When we think about the theft of a Lamborghini or a Rolls-Roycethe usual thing is to imagine a physical scene: a forced lock, a broken-in garage or, in the most cinematic version, an interception in the middle of the road. That image is still very present because for years it was the most visible form of this type of crime. However, In the last two years, a different and much less obvious fraud has spread. Some of these cars do not disappear on the street, but at a previous and almost invisible point: the digital process that organizes their transportation from one city to another. Imagine this scene: someone buys a luxury vehicle in one city and organizes its transfer to another through a common service in the sector. The car is loaded onto a closed trailer in front of the owner, the documentation appears correct and the delivery schedule fits what is expected in an operation of this type. Everything responds to a logistical routine that, in theory, should be resolved in a few days without any problems. However, in some cases this outcome never occurs and the vehicle ceases to exist within the planned route. When theft sneaks into logistics To understand where the problem really begins, we have to look at a piece that is little visible outside the sector: the so-called “load boards”. These are digital markets where dealers, manufacturers or owners publish the transfer of a vehicle between two pointsindicating origin, destination, dates and price, so that carriers or intermediaries accept the order. This system has gained weight because it streamlines operations that previously depended on phone calls and personal relationships. For example, the platform Central Dispatch It is one of the best known in the sector in the United States. The gateway to that system does not require forcing anything physical, but rather taking advantage of known weaknesses in the digital environment. One of the most used methods consists of emails phishing that appear to come from the transport platforms themselves. When a broker or carrier enters their credentials on a fake page, the attacker gains real access to their account and can operate as if they were the legitimate company. From there, you can modify contact information and start accepting high-value vehicle orders by taking advantage of that compromised digital identity. Phishing is not the only way in. The complaints also point to another less technical and more structural crack: the possibility of appear legitimate within the US regulatory system itself. To operate in these digital markets it is necessary to have a number from the United States Department of Transportation, known as USDOTwhich identifies commercial transportation companies. However, it is not particularly complex to create shell companies and obtain that identification, which allows you to present yourself to the platforms as an apparently authorized operator. With that access and that appearance of legitimacy, fraud takes its decisive step within the logistics chain itself. This, precisely, is where “double-brokering” comes into play, which consists of claiming a transport order and republishing it from another account so that it can be accepted by a driver completely unaware of the deception. This professional picks up the vehicle believing that he is performing an ordinary service and follows the delivery instructions he receives during the process, without indications that he is part of a fraudulent maneuver. The result is that the car ends up at a destination other than the one intended without, at that moment, there being an obvious sign of theft for whoever sent it. The most disconcerting thing about this scheme is that it does not require violence, not even visible action on the vehicle. Everything happens within a process that, from the outside, continues to appear legitimate: the car is collected correctly, the transfer continues and communications flow through channels that appear normal. By the time the owner detects that something doesn’t fit, the vehicle has already been delivered at a point other than planned and has left the circuit that allowed its route to be traced. This lack of immediate signals is precisely what makes fraud so difficult to anticipate. The last link in the scheme is rapid monetization. Diverted vehicles may end up resold in the United States with new papers or loaded into containers for shipping to overseas buyers. In some cases, when the owner discovers that the car has not arrived at its destination, it has already been sold or has even left the country. The impact is enough to show an underlying tension: the sector’s jump to these online markets has advanced faster than the mechanisms capable of protecting them against this type of fraud.

After a month of trying it the story is not so simple

When someone considers buying the Plaud Note Pro An inevitable question arises almost immediately: why isn’t it just an application? The doubt is not capricious. In recent years we have seen how the concept of “AI device” has surrounded itself with very high expectations and discreet results, with examples such as Humane AI Pin or the Rabbit R1 that did not convince. In this context, any new gadget powered by artificial intelligence has to justify its existence very well. The Plaud Note Pro aspires to do this from a clear focus: it does not want to replace the mobile phone, but rather to solve a specific need, that of recording, transcribing and structuring conversations. On paper its proposal is simple, but when we talk about spending almost 200 euros it is advisable to go beyond the technical sheet. That’s why our partner Ana Boria He has used it for a full month, with real meetings and everyday scenarios, to see if specialization is enough of an argument. The real test starts when you press the record button In the new video from Xataka’s YouTube channelAna shares her experience from the first contact. “It’s much smaller than I thought; “I had not seen it in person and it is very small,” he comments as soon as he takes it out of the box. That compact size is not a minor detail, because it is part of its approach: to always be at hand. Hence, one of the first aspects that stands out is its compatibility with MagSafe to attach it to the iPhone. “If you don’t have MagSafe, it comes with an adapter so you can always carry it attached to your phone,” he explains in those first impressions. The real test comes when you start recording. First, in an impromptu meeting. “I thought he was going to make mistakes and, although there is a little thing wrong with the names, he has captured the concept perfectly,” he says after reviewing the transcript. Then you subject it to a more demanding environment, with noise and several interlocutors speaking at the same time. It is in these types of situations where a recorder with AI demonstrates whether it really adds value compared to a simple app. The video also goes into issues that go beyond precision. The Plaud Note Pro promises to detect and transcribe meetings in 112 languagesbut what is relevant is how it behaves in Spanish and what happens with unusual terms or proper nouns. Added to this is the privacy section, a logical concern when it comes to personal or professional conversations. On that point, Ana points out: “It complies with a lot of measures and legislation to protect that information.” There is also a key element that determines the experience: the minute system. “I got a notice that I have a few minutes of recording left,” explains Ana, introducing one of the practical limits of the device. “The Plaud Note Pro costs 189 euros and includes an initial free plan of 300 minutes per month (about 5 hours). If you record many classes or meetings, they run out quickly,” he details. From there, the video analyzes the different plans available and which may be the most reasonable depending on the usage profile. In the end, the conclusion turns on its own nature. “Its greatest strength is simplicity and specialization“, he summarizes in the final section of the video, just before making some comments about the actual battery life. If you want to know all the nuances, strengths and limitations that he has encountered after a month of real use, You have the complete analysis on the Xataka YouTube channel.

In South America there is a bird that camouflages itself as a piece of wood. And a young Uruguayan has insisted on finding him

In the depths of the South American forests lives a bird that has inspired legends, myths and night terrors and is called the ‘ghost bird’, although his real name is urutaú. At first glance it is just a piece of wood that acts as an extension of the tree on which it perches like a chameleonbut behind this mimicry lies a biology that makes many scientists very curious to see it live even if it is really complicated. An ornithologist. The urutaú is not a bird that one finds by chance, but one must know how to look. Mauricio Silvera, a young Uruguayan amateur ornithologist who has been observing birds since he was five years old, knows this premise well, and according to a recent report from the BBCMauricio has turned observing this elusive species into a true passion. In popular culture, the melancholic song of the urutaú has fueled all kinds of folklore and rural legends in South America. However, for observers like Silvera, the true “magical power” of this species is not in the myths, but in its plumage and its peculiar way of ‘hiding’. A chameleon. It is no wonder, since we are not talking about it going slightly unnoticed, but rather its ability to imitate the bark of trees It is so perfect that sighting records on scientific platforms often require exhaustive photographic confirmation. And it is no wonder, because without this evidence it is difficult to convince the experts that they are not looking at a simple branch and a small irregularity that corresponds to this bird. How he does it. Disappearing in broad daylight is not something easy to achieve, but here science has different answers that go far beyond the simple color of their feathers. The key is in visual crypsis, where research shows that these birds not only have a plumage pattern that blends with the environment, but also make active decisions about where to perch in trees. And it is that a 2017 study on the choice of backgrounds showed that these birds carefully select the place where they rest to maximize the coincidence of patterns with their environment, which increases the survival rate against predators. And if they don’t see it, they can go completely missing. Modify your smell. Beyond the visual, researchers were able to see in a fascinating 2022 study that these birds have the ability to change your scent profiles in different seasons to prevent predators from being able to smell them. Echolocation. Unlike most birds, owls have developed this system, emitting acoustic signals to navigate in the darkness of Venezuelan and South American caves, similar to bats. Furthermore, their role in the ecosystem is vital, since research into the “secret life” of these birds reveals that they are formidable seed dispersers. They spend entire days in the trees regurgitating the seeds of the fruits they consume, acting as true foresters who maintain the ecological connectivity of Neotropical forests. A story of the search. As we see, it is not easy to find this bird and that is why Mauricio Silvera relates that finding it is “an adrenaline rush like in the chest of not knowing what to do: whether to scream, take the photo and tell someone.” Even this biology student makes a very comical simile when he sees that it is “almost like looking for Pokémon and seeing how many little birds you find and if you find the rarest one.” Your adventure always begins with a location or a photo that indicates that the bird may be present in a specific place. But due to its great ability to hide, it means that your trips do not always end with a photograph of this bird, much to your misfortune.

why is it still visible today

From space, everything looks different. Without going any further, the barrage of precipitation that ha cracked face of the peninsula. Or that one of the human structures that are best seen from space They are the greenhouses of Almería. From space the mountain ranges are striking, but in Africa a dark line that cuts the terrain for hundreds of kilometers draws attention and is not a road. Its existence dates back 2.5 billion years, more than half of Earth’s history. And the reasons why it is still visible today also explain why it will still be there in so many millions more: it is the Great Dam of Zimbabwe. First of all, a couple of nuances about its name: it is large and crosses Zimbabwe but it is not a dam: it is the longest known continuous rock intrusion on the planet, according to the Zimbabwe Geological Survey. Or rather, a lopolito. It is 550 kilometers long, between 3 and 13 km wide and protrudes up to 450 meters above the plateaus of the Zimbabwe Craton. Throughout history, NASA has photographed this geological landmark on several occasions on various missions, mainly through its Earth observation satellites and also by astronauts. Its image is so characteristic that it works as a reference point from space. Live Science collects which in 1983 was immortalized by astronauts aboard the space shuttle Challenger, collecting only the southern part of the structure. In 2000, a 62.2 x 39.2 kilometer section of the Great Dam was captured by the Advanced Space Thermal Emission and Reflection Radiometer (ASTER) satellite, aboard NASA’s Terra satellite: NASA/GSFC/MITI/ERSDAC/JAROS, and US/Japan ASTER Science Team Zimbabwe’s Great Dam is much more than a geological landmark If there is an iconic and detailed photograph from space, it is it that of September 30, 2010. It was taken by an astronaut on the Expedition 25 crew of the International Space Station with a Nikon D2Xs camera and a 180mm lens. POT 2.5 billion years ago, molten rock from the Earth’s mantle found cracks in the crust to climb between existing rock layers. As it cooled, it solidified into a mass of truly hard rock: the Great Dam of Zimbabwe. The slowness of this process and the stability of the craton explain why it has survived erosion practically intact for millions of years. The Great Dam is like a time capsule: That this enormous formation has survived undeterred allows the scientific community to study what the interior of the Earth was like at that time, something that is not possible in most of the planet. And of course, it makes it still visible from space. As the magma rose and cooled, the minerals separated and concentrated in layers like sediments, leaving large accumulations of platinum, chromite, nickel, vanadium and gold. Because the Great Dam of Zimbabwe also has great strategic and economic importance, as it houses the world’s third largest reserve of platinum and contains other critical minerals for the technology industry.

In 1985 the most valuable company in the world had 400,000 employees. In 2026 the most valuable company in the world will have 40,000 employees

36,000 employees. Is the approximate number of the template of what, today, is the most valuable company in the world: NVIDIA. It may seem like a lot of employees, but the figure takes on another dimension when we compare it to what was the most valuable company in the world, IBM, which once had a whopping 400,000 employees on its payroll in 1985. More inhabitants than many cities The IBM of the 80s needed a veritable army of employees to function. It reached its peak in 1985, with a total of 405,000 employees hired all over the world, a figure that exceeds the population of cities such as Alicante, Bilbao or Córdoba. Currently, large technology companies have enormous staff, but all of them are very far from what IBM was (except for Amazon which due to its global retail business, has a much larger staff). According to bullfincher datathis is the number of employees of the big tech: Alphabet (Google): 190,000 Microsoft: 228,000 Apple: 166,000 Goal: 78,000 NVIDIA: 36,000 The case of NVIDIA draws attention, which with only 36,000 employees stands out as the most valuable company of the moment. Right now its market capitalization is 4 trillion dollarsalthough reached 5 billion at the end of last year. And what about the money? But let’s get to the important thing: How much money did IBM generate with that workforce? They count in The Chip Letter that, in 1985, IBM brought in 50,000 million dollars, which adjusted for inflation it would be about 150 billion dollars. Let’s see how it looks compared to what big technology companies entered in 2025: Alphabet: 402.8 billion Microsoft: 281.7 billion Apple: 416,000 million Goal: 200,000 million NVIDIA: 130 billion (2024) IBM was a true giant in its time, but even adjusting for inflation, its income pales compared to what big technology companies earn today. The only exception is NVIDIA, which has not yet reported its results for 2025, so the figure is that of 2024. Still, if we compare the volume of employees, NVIDIA makes each employee much more profitable. We talk about $3.61 million per employee compared to $370,000 per employee in the case of IBM, almost ten times more profitable. Productivity has skyrocketed How have companies managed to maximize profitability per employee? The key is in digitalization and how it has boosted productivity. Already in 2013 there was talk that technology had made Productivity will increase by 480% since the 70s. If we go to the specific case of IBM and NVIDIA, the first was mainly dedicated to the manufacture of mainframe computers or mainframesa process that in itself was much more laborious, at a time when manufacturing more meant having more employees on production lines. NVIDIA is a company fablessmeaning that those who manufacture their GPUs are other companies like TSMC, and they also do it with much faster and more efficient automated processes. This leaves its 36,000 employees “free” to focus on chip design and architecture, allowing them to scale faster and with much less labor. However, there is something in which no technology company manages to surpass what IBM once was: its degree of transversal dominance. He kept around the 70% market share mainframes, But it was also a leader in minicomputers, microcomputers and the software that accompanied them, from databases to compilers.

We thought it took us a long time to learn to cook. Until some 780,000-year-old carp teeth rewrote history

If we think about the technology that has most transformed humanity, it is easy for the wheel, the steam engine or the microchip to come to mind in a more current way. However, there is a much older and more fundamental “technology” that literally changed our anatomy: the kitchen. The evolution. For decades, paleoanthropologists have debated At what exact moment did our ancestors stop consuming raw foods to start processing them through the control of fire. The most recent evidence not only rewrites our chronology, but confirms that mastering cooking was the true driving force of human evolution. How do you know? Date something as precise as the beginning of cooking, but the reality is that Until recently, indisputable evidence of the continued use of fire for cooking They were around 600,000 years old. However, a great finding published in the prestigious magazine Nature in 2022 set back this evolutionary clock. In this case it was at the site of Gesher Benot Ya’aqovin Israel, remains of large carp teeth were found. With these samples and through advanced techniques such as X-ray diffraction, the researchers demonstrated that these remains had been exposed to controlled and relatively low temperatures, being less than 500 °C. The first date. With this evidence it seemed quite clear that it was not an accidental fire, but rather that it was dated 780,000 years ago these animals began to be cooked. This is consistent with the fact that Acheulean hunter-gatherers were already exploiting aquatic habitats, selecting nutrient-rich fish and cooking them in what archaeologists call “ghost hearths,” which were structured fire zones. Another hypothesis. Although direct evidence pointed us back to 780,000 years ago, biological clues suggest that the culinary revolution began much earlier. This is what primatologist Richard Wrangham pointed out, in his book Catching Fire and in subsequent studies published in Current Anthropology, proposing that systematic cooking emerged with Homo erectus approximately 1.9 million years ago. Your arguments. To be able to give this date, this expert focuses mainly on energy efficiency, since he points out that cooking predigests food, breaking down fibers and starches. This allows you to obtain many more calories with minimal effort. But the most relevant thing is that by facilitating digestion, the Homo erectus It no longer needed a massive intestinal tract to process hard, raw vegetables. And here size matters, since intestinal tissue and brain tissue are energetically very expensive, and so, by shrinking the intestine, the excess energy could be redirected to the growth of a much larger and more complex brain. But this softer diet also explains why the molars of the Homo erectus They shrank and their jaws became less prominent. Beyond nutrition. The implementation of cooking not only brought anatomical benefits, but studies indicate that in the case of the first hominids, this was essential for roasting raw meat and killing the bacteria that were inside. But in addition, fire control and the ability to process food were key tools that facilitated human migration. In reassessments of classic sites, such as the Zhoukoudian caves in China, they confirm that the Homo erectus pekinensis used controlled fire to cook deer meat in specific stratademonstrating that this practice was essential for adapting to colder climates outside of Africa.
