Reddit has become the best human data source. AI is trying to prey them

by

Everyone wants Reddit data. And they want them why they are data humans. That is the Great value of a platform which has become the crown jewel of AI companies. They want to use that data To train their AI modelsand Reddit is tired of trying without asking for permission … and without paying. Reddit demands Anthropic. The social network, fed up with this type of behaviorhas registered a lawsuit against Anthropic, the creators of Claude, so consider a contract violation and for participating in “illicit and unfair commercial acts” when using the platform and data of the social media company without authorization. Or what is the same: for stealing the data for your AI. Blunt criticism. In The demand Reddit’s legal managers begin strong: “Anthropic is an artificial intelligence company of late flourishing that proclaims the white gentleman of the artificial intelligence industry. It’s anything but that.” According to Reddit, Anthropic shows a public face in which he presumes his respect for the law and doing things legitimately, and another private “that ignores any rule that interferes with his attempts to fill his pockets even more.” Human data treasure. Reddit has become In a valuable source of human information. If someone looks for answers, experiences and opinions in raw, this is the platform that has ended up becoming an absolute reference. In Reddit they know it. His legal manager, Ben Lee, explained in The Verge the following: “Reddit’s humanity has a unique value in a world flattened by AI. Now more than ever, people seek authentic conversations between humans. Reddit houses almost 20 years of rich and human debates about practically all imaginable topics. These conversations do not occur anywhere else and are fundamental to train linguistic models such as Claude.” Reddit began to protect himself very soon. Knowing that his “human data” were that great treasure with which to make box, Reddit began to make movements for take advantage of that data very soon. A few months after the launch of ChatgPT, it appeared that He made his APIas shortly before I had done Elon Musk with X/Twitter. He controversial movement It was clearly aimed at protecting the platform from those birds of prey in which IA companies had become. Then the demands would begin. If you want my data, pay. Reddit’s policy has been clear from the beginning, and there have been companies that have assumed the message. Google was one of the first to reach an agreement with Reddit and paid 60 million dollars to the platform To train your AI models with that data. OpenAi ended up doing the samealthough the amount that was paid to Reddit has never been revealed. Anthropic Discrepa. An Email from Anthropic to CNBC reveals that “we disagree with Reddit’s complaints and we will defend ourselves vigorously.” Interestingly, Anthropic herself has blocked the access of her Claude model to Windsurf, the newly acquired programming startup by Openai. One of its co -founders He affirmed that “it would be rare for us to sell (the API of) Claude a OpenAi.” It is a reasonable argument – and debatable – but it does not seem to be equally logic in the case of Reddit. But it already has other pending demands. That statement contrasts with two other demands that Anthropic has received in the last two years. Last August, three authors sued it in a Federal Court in California for having “built a billionaire business stealing hundreds of thousands of copyright“Before, in October 2023, Universal Music also sued her in Tennessee for a” systematic and generalized violation of the copyright of the lyrics of his songs. “The record giant He lost that battleHowever, which meant a disturbing victory for the technological ones. Internet looting continues. It is another case of that Absolute looting that AI companies are carrying out on the Internet. None of them savealthough of course there are flagrant cases such as perplexity or the recent scandal of Goal downloading books from books with copyright to train their models. If there are data that can be used to improve the quality of these models, companies try to get them, and it is just what happens with Reddit. The IAS do not want copyright. This whole process is part of a worrying phenomenon: there is still not punishment for all these companies despite being violating copyright. Openai already asked for a white letter to operate In that field, but other companies They joined that unusual proposal to eradicate copyright lawsat least for their AI models. The argument of “fair use” remains its great shield in front of these demands, but the reality is that the months go by, we insist, there is still no consequences for this flagrant robbery of the internet content.

We have found the oldest human fingerprint in the world. He is 43,000 years old and someone left her in Spain

by

Now we know a scene that occurred thousands of years ago. It happened more or less like this: a Adult Neanderthal He found a granite shot whose irregular shape, rich in quartz and natural clefts, possibly evoked for his eyes more than a simple stone: it looked like an elongated face. What followed was a seemingly minimal act, but full of significance. He left the oldest human footprint ever known, and did it in Spain. The art of Neanderthals. The scene has now described the scientists and calculate what happened about 43,000 years in what is today the province of Segovia. As explained in the study Recently publishedthe adult Neanderthal wet his finger in red pigment and pressed with him the stone just where the nose of that possible face would be, thus leaving the oldest human fingerprint ever recorded. The discovery, made in 2022 in San Lázaroit has been verified through an interdisciplinary team of archaeologists, geologists and forensics, which have concluded that the reddish point contains iron oxides and clay minerals not present in the cave, indicating that the pigment He took intentionally From another place. Art. Unlike a tool or utilitarian utensil, the stone did not present signs of practical use: its value was symbolic, aesthetic, or perhaps spiritual. The red pigment point, without which the object would not have archaeological value, marks the decisive step between the merely physical and the cultural: between the stone and the idea. The stone found The meaning behind the gesture. The authors of the study, published in the magazine Archaeological and Anthropological Sciencesthey argue that the finding reinforces the hypothesis that the Neanderthals had a symbolic mind similar to that of Homo sapiens. For them, the act of selecting a stone for its shape, transporting it, applying a precision pigment and probably attributing a meaning is proof of the existence of at least Three cognitive processes Complexes: the mental conception of an image, the will to communicate something through symbols, and the ability to attribute meaning. This triad, they affirm, is the art base. In that sense, the simple pebble with a red point can represent one of the oldest human face abstractions of the European prehistoric record. The uniqueness of the object makes it a difficult piece to contextualize: there is, for now, another equal. That said, remember that your artistic dimension cannot be ruled out. On the contrary: its rarity reinforces its character as an isolated, but revealing example, of the ability of the Neanderthals to Project thoughts and ideas about the material world. Breaking prejudices. There is more, of course. The finding highlights not only the original act of that Neanderthal, but also the persistent modern resistance to consider these hominids as authentic art creators. As explained Archaeologist David Álvarez Alonsoif it were a human intervention dated just 5,000 years ago, no one would hesitate to classify the object as art portable. But the fact that a Neanderthal has produced a debate that is not strictly scientific, but also cultural: our resistance to accepting that others Humans, extinct about 40,000 years ago, shared with us not only tools, fire and hunting strategies, but Also imaginationsymbolism and the need to represent. Under that prism, the stone of San Lázaro breaks that taboo with a single footprint. It is not a mural, nor a petroglyph, not even a figurine: it is a unique gesture on an ordinary support, one that, they assure, demands a deep rereading of what we consider “art” and who can produce it. A window The researchers tell In his work that the trace of pigment, interpreted as a deliberate act, forces us to ask ourselves for the Mental process that led to that moment. The first: What did that Neanderthal see in the stone: a face, a spirit or a sacred object? We will never know, but what the intervention suggests is a will to assign meaningto highlight, to leave a brand (mark). As the team points out, the total absence of pigments in the surroundings of the cave suggests A firm intention: The stone was collected, transported and altered with purpose. If we also want, in its apparent simplicity, the finding contains a complexity that forces us to reconsider the conception of the human being. If the Neanderthals could look at a stone and see a face in it, and then intervene it so that others would also see it, then they shared with us something essential: The ability to transcend the immediate and imagine the invisible … through a simple sign.

The great AI companies have declared a underground war to a pillar of education: human teachers

by

We would all like to have a Keating Professor In our lives. One that made us get on the desks to see things from a different perspective and that he would teach us that the most important lesson he has for us is summarized in the words “Carpe Diem”. There are very few who approach that image, but all of them, bad or good, threatens them the same future as Other professions: Be replaced by an AI. Professor 24/7. The narrative of several AI companies is clear: the human teacher is a bottleneck. Each of them serves many students, their knowledge is limited and their finite availability. The AI, they assure those companies, proposes a remarkable alternative. Personalized professors 24/7 with infinite patience and access to all the knowledge of the world. There is a clear problem: that message devalues ​​the teacher’s function as a guide, mentor and catalyst for curiosity and reduces it to a mere transmitter of information. Continuous evaluations. Another of the pillars of the educational system – and one of the tasks that most consumes the teaching staff – is Student evaluation. The AI ​​promises to correct efficiently, massively and immediately, releasing the teacher for other tasks. But again in human evaluation there is much more than a mere correction of errors. The effort, the reasoning process, creativity, originality or even the personal context of the student are evaluated. Biases also pose a clear threat to these evaluations, in addition to promoting a model Based on the correct answer and not in the reflexive process. My school is OpenAi. So far schools, universities and other academic institutions are the guarantors of a theoretically coherent and quality curriculum. The approach of the companies of AI would be that of Become them In “Guardians of knowledge” deciding what is important to learn and how. The risk: lead to a fragmented education and dictated by the interests of the market, eroding the role of education as a pillar of society. Threat to humanities. The AI ​​also raises the irrelevance of memorization – it can already respond to all known knowledge – and bet on skills such as “Prompt Engineering“(know how to ask things to AI) or Technical subjects (Stem). That suggests a clear impact to matters of humanities and critical thinking that we do not apply directly. Fields such as philosophy, art or social skills, hardly quantifiable, would go to the background. The objective would not be as much to train and prepare workers for the technology industry. Goodbye to social investment. Companies that bet on that model have a clear objective: climb and be profitable. AI technology applied to education promises a lot of savings (less physical infrastructure, less teachers) and a highly scalable business. But also imposes a worrying revolution to one of the pillars of society. Bill Gates believes in the future of the teachers of AI. Among the experts who outline that idea is the figure of Bill Gates, co -founder of Microsoft. His commitment to the teachers of AI It was early: Chatgpt had been in the market for just five months when he said that “AIs will reach that capacity, to be as good tutors as any human being.” For him, this technology should also be a “leveling” for society. According to Gates “having access to a tutor is too expensive for most students, especially if that tutor adapts and remembers everything you have done and review your work.” Openai and Khan Academy have the same vision. A year ago the presentation of GPT-4O surprised among other things for that capacity offered by this AI model to talk directly to him. One of the OpenAI demos, carried out in collaboration with Khan Academyhe showed Sal Khan, his founder, contemplating how his son used the model to receive a geometry lesson. The interaction was impeccable and pointed to a future full of teachers of ia locked in our tablet, our mobile or our computer. Khan is of course interested, but it doesn’t hurt see your ted talk on “how AI could save (not destroy) education.” Schools converted into nurseries. Luis von ahn, Founder of Duolingothe poular application to learn languages, it also takes time turning towards the AI. A few days ago he participated in the podcast No priorsand there he commented how although there are very good teachers, “there are not many.” For him, education will change radically because “it is much more scalable to teach with which with teachers.” Even so pointed out That does not mean that teachers disappear: “You will continue to need people who take care of students”, but focused on a new role: “I don’t think schools disappear, because you need nurseries.” Image | Buena Vista Pictures In Xataka | Towards the end of duties: how chatgpt has been inserted in the center of the great debate on education

The arrival of the human being to South America, seen through the DNA of the heirs of the last great migration

by

Throughout our history as a species, Homo sapiens We have managed to reach the most remote corners on Earth. Millennia before the era of exploration, our ancestors undertook a trip that took them out of Africa and populate the great continental masses from Europe to South America. Among all these great migrations, one of the most surprising was the one that led humans from Siberia to Patagonia, a 10,000 trip whose details are knowing. History in genes. A new genetic study has given us new clues on the great migration that resulted in the population of the Americas. A migration of 20,000 kilometers whose implications still last in aspects as apparently distant as health. The study allowed to draw the history of migrations until the considered “final border” of human migrations, Tierra del Fuego, Explain the team responsible for the study. History of a millennia trip. This great migration would have begun in Siberia between 27,000 and 19,000 years ago Approximately during the last glaciation, in what we know today as the Bering Strait would have formed a “bridge” of land due to a lower sea level than the present. Through Alaska, these populations would have arrived in North America, but the expansion through this continent would have been only an intermediate stage. The study focuses on the second part of the trip, when part of the new American population crossed the Central American Isthmus to enter the last continent in being populated. The last border. The new genetic analysis allows us to know how humans expanded in South America. The responsible team detected that lineages In this continent they began to diverge with each other between 14,000 and 10,000 years ago. From this point, the South American population began to separate into four groups. The first to disintegrate was those who populated the Amazon basin, while the rest was distributed among the high areas of the Andes mountain range, the desert area of ​​the Chaco, and finally, Patagonia. Reading migration in genes. For its study, the team sequenced the genomes of 1,537 individuals belonging to 139 villages of the continent. The details of the study were published In an article In the magazine Science. Very long -term implications. The consequences of this migratory movement and its vicissitudes still last and some of them still weigh on the native peoples of South America, especially as a consequence of the isolation of some of these populations with respect to the rest of humanity. This could explain why some populations were more susceptible to the introduction of infectious diseases by the first Europeans to reach the continent. “Those migrants carried only a subset of the genetic heritage in their ancestral populations (…). Thus, reduced genetic diversity also caused a reduced diversity in immunity -related genes, which can limit flexibility when fighting several infectious diseases,” stood out in a press release Kim Hie Lim, Co -author of the study. From the past to the present. Knowing new data on the genetics of American peoples can also help us in the present. This information is valuable when studying treatments of genetic diseases, or to better understand the functioning and impact of certain medications. In addition, the closest relationship between American and Asian populations implies new data on a population that, recalls the team responsible for the new work, covers 50% of the world’s population.

Only three countries have launched human beings to space. A room is about to join the club: India

by

The last great spatial power is preparing to register its name in one of the most exclusive clubs of humanity: that of nations capable of sending astronauts to space by their own means. Until now, only the United States, Russia (heiress of the Soviet Union) and China hold that honor. But India and its ambitious Gaganyaan program are knocking on the door. In two years. Announced in 2018 by Prime Minister Narendra Modi with the aim of launching in 2022, to coincide with the 75th anniversary of the country’s independence, the Gaganyaan program accumulates several delays. However, the Indian Space Research Organization (ISRO) has stepped on the accelerator, confirming that, although the first manned mission is postponed in early 2027, preparations advance at a good pace. The road map. Isro prepares three unmanned orbital missions of the Gaganyaan ship before starting to launch astronauts, According to Eureka. The first is called G1 and is scheduled for the last quarter of 2025. The Vyommitra humanoid robot will carry on board, loaded with sensors to prepare manned flights. The G2 and G3 missions will be followed in 2026, also with Vyommitra. And, if everything is going as planned, Mission H1, the first manned, will take off in the first quarter of 2027 aboard the HLVM3 rocket (a version of the LVM3 adapted for manned flights), followed by the H2 mission. Astronauts. India has already designated four astronauts for these historical missions: the pilots of the Indian Air Force Prashanth Balakrishnan Nair, Angad Prathap, Angad Pratap and Shubhanshu Shukla, who will previously fly to the International Space Station in the Axiom 4 mission aboard a Spacex ship. Everyone has formed as astronauts in Russia and, one of them, Shubhanshu Shukla, will have a previous experience this one before, when it flies to the International Space Station aboard a Crew Dragon ship as part of the commercial mission Axiom 4. Ambitious plans. Indian ambitions do not end with putting astronauts in orbit. After the first two manned missions, a fourth unmanned mission of Gaganyaan, the G4, will be attached to the US segment of the International Space Station with an coupling system compatible with the NASA standard. Will serve as proof of concept to put the orbit the first module of the Indian Space Station Bharatiya Antarksha Station (BAS), whose first module would be launched in 2028 in an orbit similar to ISS. The first load mission to BAS, the G5, is scheduled for 2029. BAS has the objective of establishing a permanent presence of Indians in low orbit, adding to China, which has its own space station, and the ISS member countries, which will be abandoned in 2030. The next step will be to put an Indian astronaut on the lunar surface by 2040. For this, Isro is developing a new generation rocket propelled by methane, the NGLV (Next Generation Launch Vehicle), which will have a version capable of placing 70 tons in low orbit.

When human talent is no longer essential

by

Duolingo has taken a step that seems small, almost technical: it will replace part of its network of external collaborators with generative. His CEO announced it, Luis von Ahnin an internal email that Then he posted on LinkedIn. But after that phrase that sounds corporate because it is – “we will be a company Ai-first” – A larger turn is hidden. Not only in your strategy. In the type of world we started to live. What Duolingo has done is not simply automating tasks. Is Demonstrate that, in certain industries, human talent is no longer a necessary condition to create value at scale. What was previously slow, expensive and artisanal – create formative content – can now be synthesized in mass and in seconds. Without exhaustion. Without payrolls. No creative demands. In silence. In the last thirty years, the Internet put us in An economy where human capital – ideas, creativity, language, criteria – was the great bottleneck. People were still essential. But we are seeing the beginning of decoupling: the separation between digital value and direct human contribution. A new starting point. The generative AI not only replaces tasks. Is starting with redraw the merit border. Knowing how to do something well is not enough. If a machine can do it “sufficiently”, you can get out of the map. Although your version is better. Although your criteria is finer. The qualitative differential no longer compensates for the speed and scale. And in that logic, talent ceases to be a protected asset. It becomes optional. Duolingo will not be the only one. It has only been the first to say it without surroundings. It sounds like a sample of what is coming. Companies that no longer hire if they do not automate, Like shopify. Departments in which it is measured how much value you contribute with ia, not without it. And a new type of worker that must show that it is still competitive … in front of a machine. This moment marks A rupture. Creativity, for decades, was a shelter against automation. Now is your next land. And that forces us to ask ourselves more uncomfortable questions: if talent is no longer essential, what is the place of human work in the digital economy? What remains of professional prestige when excellence no longer guarantees relevance? The story will remember this gesture of Duolingo not because of its immediate effect, but for what it anticipates. A new phase. More than a technological change, a mutation in the rules of the game.

The human voice loses ground and automatic dubbing with AI makes its way between creators

by

Artificial intelligence (AI) continues to gain space in unthinkable sectors just a few years ago. What began revolutionizing software development is now leaving a mark on very different fields. The phenomenon of ‘Vibe Coding‘, a new way of programming based on Prompts In natural language, without writing code as such, the rules of development are changing. At the same time, tools such as Dall · e of OpenAi or Adobe Firefly They are redefining visual creation, allowing generating images and videos from textual descriptions. And now, AI also reaches voice professionals. For a few months, YouTube allows some creators to use automatic dubbing through AI. This function, which is being deployed progressively, is now available for all members of the YouTube Partner Programa system that allows creators to monetize their contents on the platform. Thanks to this tool, videos can reach global audiences more easily, as an alternative to traditional dubbing and postproduction processes. An activated function by default. One of the most striking changes is that this function is activated by default: if you upload an English video, YouTube will automatically double it in several languages, including Spanish, French, German, Hindi, Indonesian, Italian, Japanese and Portuguese. If the video is in any of those languages, an English version will be generated. The objective, according to the company, is to “break the barriers of the language.” But if the creator prefers not to use this function, it can deactivate it following concrete steps: enter YouTube Studio from the computer and follow this route: Configuration > Subsequent adjustments > Advanced configuration. There you have to uncheck the ‘allow automatic dubbing’ box and click on store. The management of this function, in addition, can only be done from YouTube Studio on a computer, and allows you to even manually review dubbing before publishing them if you want greater control of the result. YouTube admits that technology still has improvement margin. Translations may not be exact and the generated voice may not faithfully represent the author. In fact, the company itself recognizes that intonation, emotional tone and certain cultural nuances do not always move correctly. The basis of this function is in the technology of Google Deepmind And Google Translate, but even with that background infrastructure, not all videos can be folded successfully. Factors such as the original accent, the background noise, the use of jargon or even proper names can affect the quality of dubbing. A video with automatic YouTube dubbing To know if a video is bent with AI, it is enough to look for the “auto-dubbed” label. It is also possible to change audio track from the player’s menu, through the gear icon in the lower right corner. The language adapts to that the user has configured as preferential, which makes the experience, in many cases, more transparent. We can see the active function in this example video. The prelude: real dubbing with professional actors. YouTube had already taken previous steps in this direction. With the function “Add audio track“, Some creators like Mrbeast They began to offer versions of their videos in several languages using professional voice actors. He even counted With the dubbing actress that plays Naruto in his videos in Japanese. This strategy, focused on expanding the scope of the content without losing interpretive quality, allowed many of these videos to reach new audiences. Mrbeast has not been the only. According to YouTube datathe videos that offered versions in several languages ​​made more than 15% of the visualization time come from audiences that saw the content in a language other than the original. In January 2023, users came to consume more than 2 million hours of folded content every day. And that only with the initial tests. The extension of this function to all members of the Partner Program is contributing to the growth of the use of voices generated by artificial intelligence on the platform. This raises questions about how this technology will be integrated into the professional dubbing ecosystem. Some creators could opt for this automatic alternative in certain types of content, especially in informative or structured pieces. However, in other formats where vocal interpretation provides key nuances, the role of dubbing professionals remains a difficult element to replace. Development continues, and the balance between technology and creativity is still evolving.

China has just resolved one of the advantages of human hunting pilots in front of AI: interpreting the unpredictable

by

There was a small redoubt in military key where “human strength” continued to be imposed on algorithms. When it comes to Air Force and the management of combat aircraft such as the Ultra Popular f-16 huntingthe pilots had an advantage that paralyzed the advance of the AI: they were unpredictable in their maneuvers. They may have the days counted. China has found how to anticipate. The end of the human advantage. In A study Published a few weeks ago, China seems to have achieved an unprecedented advance in air combat. As? By eliminating the last tactical advantage of human pilots over artificial intelligence: the ability to maneuver and high intensity to evade attacks. A team of researchers from the North -Western Institute of Mechanical and Electrical Engineering, a key branch of the Norinco Armament Gianthas developed a system that combines advanced infrared images with predictive modeling of AI to Precision anticipate movements of an opponent by detecting subtle adjustments on their control surfaces, such as ailerons and rudders. The study. The advance, detailed in a work published in December in it Journal of Gun Launch & Controladdresses a key limitation of AI systems in air combat: their dependence on trajectory -based predictions, which also fail to respond effectively to non -linear and sudden maneuvers of human pilots. The team, led by engineer Lin Zhiwei, overcame this problem by focusing on the Physical mechanics of enemy aircraftallowing AI to interpret millimeter movements on the control surfaces to predict actions before they are completed. How it works. As detailed, the system is based on the use of a modified neuronal network Yolov8the same that analyzes infrared images and Detect microdeformations In the components of the plane, such as the rudder of 1.5 meters from an F-15 or its two-meter stabilizer. These data are then processed in a long and short term memory network (LSTM) Improved with care mechanisms, which allows anticipating the pilot maneuvers in real time, without depending solely on previous flight patterns. In simulations, AI managed to reduce prediction errors less than two meters. It is no small thing, let’s think that it is an improvement of ten times with respect to traditional systems. Applied to automated anti -aircraft systems, this precision would even allow direct attacks directly to the pilot’s cabin if necessary. The test. In their study, the researchers tested the algorithm in flight profiles that They imitated real tactics fighting. In one of these scenarios, an F-15 launched ammunition at low altitude and then performed an abrupt ascent, a maneuver that requires a millimeter coordination of flight controls. In another case, the aircraft executed rapid evasions with erratic movements and sudden changes of direction. In both experiments, the AI ​​predicted the displacements Milliseconds in advancecanceling the pilot’s evasion capacity. A new chapter in the arms race. The advance comes at a key moment in the global race for the supremacy of AI in air combat. In 2020, The Alphadogfight Trials From the Advanced Defense Research Projects (DARPA) of the United States They demonstrated the superiority of AI in combat simulations. More recently, in 2024, an AI system participated in A real dogfight against a human pilot for the first time. The difference? The Chinese team emphasizes that its technology is designed to Optimize fire controlmore than to allow completely autonomous attacks. However, the principles of their AI align with international programs such as “loyal wingman” drones of the United States Air Force, which combine piloted airplanes with combat systems. Plus: The study also confirms that technology is viable with current hardware. Using Chinese manufacturing PS800 infrared sensors, which achieve a resolution of 0.375 miliradia at distances of eight kilometers, the required precision levels are reached For use in real combat. Limitations and countermeasures. Despite its advanced abilities, the system is not invulnerable, of course. One of its main weaknesses expressed by the authors themselves is the possible Interference for electronic countermeasures and optics (such as We have counted in several occasions). In other words: an adversary could use high -power lasers to blind or even destroy the infrared chambers that AI needs to detect the movements of the enemy. There is still a wide margin of improvement. The future of air combat. What seems clear is that the development of this technology represents a turning point in the Air War. Until now, human pilots had a fundamental advantage: what is not studied, the ability to Perform unpredictable maneuvers To avoid being shot down. However, with the ability of this algorithm described to read even the most subtle movements of a combat plane and predict their trajectory with millimeter precision, human pilots could be very close to losing their last tactical advantage and opportunity to overcome machines in a contest. The drones They started the change In real fighting, now it seems that the completely autonomous war is one step closer.

The longest land border in the world made by the human being is a gigantic firewall between the US and Canada

by

One of the most controversial borders of the last weeks is, curiously, one in which there are no war conflicts: the one that separates Canada from the United States. It is a peculiar border, with numerous rural points without surveillance and whose straight line looks like a gigantic firewall visible from spaceliterally dividing what he finds in his path. And, although it seems that something like this is a vote of confidence among good neighbors, the latest events show that even the world’s least monitored border can become tensions scenario. The longest in the world. It extends along the whopping of 8,891 kilometers and, with the signing of the Treaty of Paris Of 1783, there were the first steps to define limits in the territory of future United States and British Columbia. It was the moment in which the United States War of Independence was put an end, but the final demarcation of the border would take more than a century to arrive, and would do so in the form of a gigantic firewall. Literally: There is no need to throw imagination: that central line extends thousands and thousands of kilometers The ‘firewall’. The upper image represents a tiny border segment, in one of the rural areas. It is taken from Google Maps Because it is a border of the most visual (and I encourage you to throw a rare sailing through the app discovering curious cases). If a river or a mountain range does not physically separate the territory, Canadians and American are distanced by a gigantic firewall who, in much of the border, is still a straight line that divides forest, rural and even cities. The entire central part of the border and even the Pacific responds to that design based on parallel 49 After the Treaties of Paris and Jaythere were still fringes that would not be resolved until decades later, but one of the decisive moments arrived at the London Convention of 1818. In it, the 49 parallel was established as the border between the two countries, from the Lake Forests to the Rocky Mountains. In 1846, the Oregon treaty The witness collected, continuing the decision that the 49 parallel marked the border from the roco mountains to the Pacific, except a Vancubert that remained in the northern domains. The firewall and a road portion that gets into Canada … and returns to the US Even so, there were borders that were still clear, such as Alaska, so arbitration was created specifically designed for that border. In 1908 the border was consolidated in the International Limits Commission. It was then that the decision was made to physically demarcate the division, creating an immense firewall or strip that definitely marked the limits of each country. The border is full of these markers that delimit the state to which each area belongs Together, but not scrambled. Imagine that you are playing a video game and you want to define a division without you care where the lines fall. Well, a similar case is the one that is lived in some locations that have part of the territory in the United States and part in Canada. It is not that there are curious cases such as Mexico City (which on one side of the street are in the State of Mexico and, in the other, in Mexico City), but that there are buildings with a division that marks that its plant is in two different countries. An example is the Library of Derby Line, Vermont, or Stanstead, Quebec (depends on the side of the border on which you are). On the floor of the reading room there is a black line that marks the country where you are, being one of the most curious cases, but not the only one. In Vermont and Quebec there are houses that catch in the middle of the border, cases such as the Halfway house, which was a tavern/hotel built in 1820 before that part of the border was established and other examples of land with part in the United States and another part in Canada. The house in the US, the tools house in Canada Golf cart parked in the US, Hoyos in Canada Half of the house pays taxes on one side, the other in the other. It is a joke, but there are few constructions that share country Point Roberts. But there are not only lands split in half: also areas that belong to one of the two countries and those that are only land link through the opposite nation. Maybe Alaska is the most famous – also the largest – and, although connected by the Arctic and the Pacific through ship, if you want to go by land you can only through Canada. Point Roberts is one of the curious examples. It is located in the state of Washington and is the ‘piquito’ of a peninsula only accessible by land through Canada. It is one of those cases in which you cross a street and pass from the Canadian city Delta to the American Point Roberts. Point Roberts Something similar occurs with Elm Point, a small uninhabited cape surrounded by lake except by the north, being Canadian territory and the only way to access by land. There are many more examples like this, such as the island of Province whose southern end belongs to the United States and where we can see another example of that firewall we were talking about before. Elm Point Elm Point closely Machias Seal. But of course, so many situations of a territory cut by the border gives rise to some tensions, and the best example of this is that of the Machias Seal Island. It is an island in the Gulf of Maine that is administered by Canada, but which the United States claims as theirs. No one lives, but there is a lighthouse built in 1832 in which Canada maintains Coast Guard personnel. And the reason for this interest on the … Read more

We have been studying the oldest remains of a human in Atapuerca for more than two years. And we still know what species belonged to

by

In the summer of 2022, those responsible for the Atapuerca site, in Burgos, made known An important find. It was about what seemed to be the face of the oldest hominid found throughout Europe and lived more than a million years ago in the north of the Peninsula. Almost three years later, we know new details about this primitive human. Pink Details such as the name with which they have baptized the individual to whom these bones belonged: Pink. The study has corroborated the initial estimates of the team responsible for the finding, which at the time already indicated that we are facing The oldest human in Europe of which we have record. The new estimates date the remains in a period that goes Between 1.4 and 1.1 million years ago In time. This implies that the fossil is several hundred thousand years before the oldest remains of the deposit (belonging to a Homo antecessor), dated about 860,000 years ago. Homo affinis erectus. An important fact that still remains to be elucidated about the species belonged to this individual. The new work confirms that the individual did not belong to the species Homo antecessoras the remains found in the Great Dolina. The specimen would have belonged to an old Homo erectus. That is why the remains have been classified in a “provisional” way as a member of the species Homo affinis erectus. “Homo antecessorShare with Homo sapiens a more modern -looking face and the projection of the bones of the nose, while Pink’s face configuration is more primitive, with features that remember Homo erectusespecially in its nasal, flat and poorly developed structure ”, explained in a press release María Martinón-Torres, director of CENIEH. June 2022. The fragment was found by Edgar TéllezMember of the Atapuerca research team, in June 2022. cataloged as ATE7-1, the remains were found in the stratum TE7 of the elephant’s chasm. After more than two years of analysis, the details of their study have been published in the form of Article in the magazine Nature. Clues about a way of life.The TE7 level can give us important clues about the environment in which Pink developed. It has recovered stone tools and animal remains with cuts of cuts, which would have been used by these presumable human inhabitants of Atapuerca and Europe. As explained by the team responsible for the study, these brands indicate that the inhabitants of Atapuerca in the lower Pleistocene not only knew the resources available in their environment, they were also able to take advantage of them “systematically”. A piece of a huge puzzle. The finding is just one more piece in the huge puzzle of human evolution and the dissemination of gender species Homo throughout our planet. We know that various waves of several species left their original continent, Africa, towards Eurasia, but the routes that followed have been hidden over time. Another important clue in this regard is precisely on a very different access route: Caucasus. A fossil gurpo found in Georgia They were so far the only track of the adventures of the H. erectus out of Africa. The oldest hominile fossils found outside the African continent were five skulls with around 1.8 million years old. These fossils were classified as H. erectusbut there are also certain doubts about this classification due to some important differences in their characteristics. This will suggest, Ann Gibbons explains In an article in the magazine Sciencethat more than one species HomoI could have left Africa in this era. The Atapuerca fossil would not belong to this species strictly, and now it gives us a new clue with which to advance in the resolution of the enigma complex.
