We have found an ancient bone in Córdoba. Some believe it is part of Hannibal’s war elephants.

What the hell is the bone of an elephant that lived more than 2,000 years ago doing in a Córdoba site surrounded by ammunition for catapults and arrows like those used in the scorpions? The question arises, but it is what a team of researchers who have just signed have been guessing for years. a fascinating article in one of the most reputable archaeological magazines in the world. In it they slip that this mysterious proboscis bone unearthed by pure chance in Andalusia could be neither more nor less than the first test direct from the war elephants employed by the Carthaginian general Aníbal Barca. What is this bone? A question similar to that must have been asked. towards 2019 archaeologists who, during a emergency excavation to expand the Provincial Hospital of Córdoba, they found a peculiar bone fragment. The piece was not larger than a baseball (measures between 15 and 8 cm), preserved its porosity and peeked out from under what looked like a ruined adobe wall from the 3rd century BC, which probably facilitated its preservation. That archaeologists unearth a bone during a tasting (even a millennia old one) has little to offer. In this case, however, the fragment held several surprises. The first, its age: 2,250 years. The second (and this is where things get interesting) is its origin: the bone is neither more nor less than the carpal bone of an elephant, something like part of the ‘wrist’ of a proboscide that for some mysterious reason ended up in the Iberian Peninsula. “He has enormous interest.” The discovery was so exciting, opening up such promising scenarios, that in 2023 it already generated interest outside the academic circuit. In September of that year Rafael Martínez, professor of Prehistory at the University of Córdoba recognized to The Country the expectation around the bone. “It is of enormous interest given the practical absence of remains of elephants from a pre-Roman context in Europe, excluding ivory objects that were subject to trade and import,” he said enthusiastically. “In any case, this discreet bone can be interpreted as proof of the presence of these animals in the area of ​​current Córdoba between the 4th and 2nd centuries BC” By then the professor went one step further and ventured a fascinating hypothesis: “It could belong to the period of the Public Wars. It could be the first elephant discovered by Hannibal’s troops, but it cannot be certain.” There were still many questions on the table. For example, its chronology: it was estimated that the animal died between the end of the IV and I BC, a long period that left several possibilities open. Did the bone belong to a Punic elephant or was it more correct to frame it in times of Julius Caesar? Hunting for answers. The bone may be small, but scientists have not had an easy time analyzing it. To begin with, it has been difficult to specify its species. After a detailed examination they concluded that it must be a large specimen, larger than female Asian elephants. Specifically, they think of a Loxodonta pharaoensis (the Carthaginian elephant) an African subspecies extinct in Roman times. Maybe the name doesn’t tell you much, but they are animals. used by Hannibal for his passage through the Alps. The other great unknown. Once the species was clarified (more or less), another unknown remained: its antiquity. The bone was a challenge because it did not contain enough collagen and had not fossilized. That did not prevent a study from ending up revealing that the fragment dates from between end of the 4th and beginning of the 3rd BC Live Science It even goes further and precise that the extract in which the fragment was found (part of a fortified Iberian town known as oppida) can be dated approximately 2,250 years ago, at the beginning of the 3rd BC It is a key fact because it takes us back to a time before the founding of the Roman Cordoba and the turbulent times of Second Punic War (218-201 BC), when Carthage and Rome struggled to dominate the Mediterranean world. Click on the image to go to the tweet. Are there more clues? Yes. And they are just as interesting. Not only was the bone found at the site, protected by a demolished adobe wall. Archaeologists also discovered more than a dozen of bolaños, small projectiles that were used with catapults, and part of what appears to be a spear. They are clues that help complete the story and help to better understand the site, such as recognize researchers in Journal of Archaeological Science Reports. “The level of destruction fits well within an emerging pattern of events associated with the Second Punic War, some of which are attested in literary sources and some of which are not, spanning both siege warfare and open battlefield contexts,” they explain in statements to Phys. Why is it important? Because of the implications it has. In your article Martínez and the rest of his colleagues recall that the discovery seems “intimately linked to the events of the Second Punic War in Hispania” and slips a key idea: “This may represent the first known anatomical element of an elephant used by the Punic troops in this war in Europe.” If they are correct, we would be looking at a first-class find: the bone of one of the elephants of Hannibal’s troops in the Second Punic War. Is it so relevant? “It could be a historical milestone. There is no direct archaeological evidence of the use of these animals,” clarify Martinez to Live Science. The march led by Hannibal through Western Europe in his attack on Rome and the use of elephants as “war machines” during the Punic Wars it is a very popular episode, but direct and palpable evidence is not abundant. The episode of passage through the Alps We know it thanks to historians like Polybius or Titus Livy, but the strongest archaeological evidence today is traces. That … Read more

To build an “artificial sun” we need to be able to move the weight of ten elephants with millimeter precision. This is what China has just done

In Chinese mythology, Kuafu was a giant who challenged the gods when trying to catch the sun to give light and heat to their people. Centuries later, China re -pursues that same ambition, but now with avant -garde science: to create a “Artificial sun” that provides clean and unlimited energy. And in that way, the engineers have just presented a new protagonist worthy of legend: a colossal robot. The arm for fusion. The Asian giant has developed a remote manipulation platform for future fusion reactors. It is a system with three robotic arms, whose main manipulator can raise up to 60 tons – the weight of ten African elephants – with a millimeter accuracy, According to South China Morning Post. Meanwhile, the two secondary arms stand out for even more extreme precision: ± 0.01 millimeters, which makes it the most advanced remote management system in the field of fusion. Closer to the “artificial sun.” The objective of this whole project is to achieve stable nuclear fusion, that almost inexhaustible energy that mimics the process that occurs in the sun’s core. In fact, China has been breaking records for years in its East experimental reactor, which this year has achieved Maintain a confined plasma for 1,066 seconds, a world record that exceeds 403 seconds Realized in 2023. But for this energy to become commercial, it is necessary to resolve a major challenge: maintenance. The internal components of a reactor, such as coating or the diving, are constantly damaged by heat, radiation and magnetic fields. And this is where this new robot comes into play: no human being could work in these extreme conditions. The in -depth project. The robot is part of the craft (Comprehensive Research Facity for Fusion Technology), an installation in Hefei, Anhui, nicknamed “Kuafu” in honor of the mythical giant. More than 300 scientists and engineers participate in this project, According to SCMPunder the supervision of the Institute of Plasma Physics of the Chinese Academy of Sciences. “We have developed a machine capable of meeting extremely demanding requirements by overcoming obstacles in materials, sensors and control,” explained Pan HongtaoInstitute researcher. The idea is to use craft as a test bank to develop and validate key fusion technologies, including those that will be applied in the future Chinese experimental fusion reactor (CFETR) and in the International Iter project In France. Ready to go into action? For now, we are not talking about an operational robot in a reactor, but of an experimental platform. According to China Dailythe system has already exceeded the evaluation of experts and will serve as an engineering verification platform to ensure that, when reactors enter into operation, remote maintenance is safe and precise. Craft, where it is housed, plans to be completed in the late 2025. Beyond fusion. Although the immediate objective is to maintain fusion reactors, technology is not limited to that field. According to CGTNthe advances achieved in this robot could also be applied in inspection of nuclear plants, aerospace industry, operations with heavy machinery or even emergency rescues. A global career for the artificial sun. The Kuafu robot does not arise in a vacuum. Other countries also develop remote maintenance systems, although with much lower capabilities. The most advanced arm of Mitsubishi Heavy Industries (Japan) supports only 2 tons. In contrast, the Chinese robot can manipulate 30 times higher loads. At the international level, the Iter project in France – in which 35 countries participate – will have a system Able to handle up to 45 tons. The new Chinese system already exceeds it in load capacity, although both remain development platforms rather than operating systems. The road map is clear but slow: Chinese experts They calculate that they are still 30 to 50 years to see commercial fusion reactors. And the European Union, with its Eurofusion projectdoes not expect to start testing with plasma until the end of this year. Forecasts The Chinese commitment to nuclear fusion advances with firm steps. The development of a robot capable of lifting 60 tons with surgical precision is not a simple engineering achievement: it is an essential piece for someday fusion reactors to maintain and function stable. Humanity He has been trying to replicate the energy of the sun on earth. With advances like this, China shows that it is determined to be the protagonist in that race. Decades may be missing to see fusion plants in operation, but every step we bring us a little more to that utopia to capture the sun.

of a 19 second video in front of some elephants to become the global video giant

“Here we are facing the elephants.” With that phrase, simple and somewhat clumsy, the history of YouTube started. It was April 24, 2005. Jawed Karim, one of his co -founders, uploaded a Video of just 19 seconds in the San Diego Zoo. There were no tripods, no hand microphones, or an editing plan. Only one person pointing animals with long tubes, a fresh spring afternoon. No one knew it then, but those 19 seconds would mark the beginning of a revolution. They say that in January 2005, Chad Hurley and Steve Chen, two PayPal employees, were at a party. People took photos and recorded videos, but sharing those videos was an incompatible formats, formats and software. “We try to simplify it as much as possible,” Chen remembered a year later in a television interview.. With that frustration in mind, Hurley, Chen and Karim began to develop a place that allowed Upload videos and share them without headaches. The first prototype, Inspired by an appointment site called Hotornotsoon evolved towards something broader: a platform where anyone could show anything. YouTube found a great ally in MySpacethe social network created by Tom Anderson: Young people filled their profiles with videos on the most popular platform of the moment. The great impulse would arrive in December 2005, when A Saturday Night Live sketch It circulated like gunpowder and triggered YouTube traffic by 83%. Suddenly, the video on the Internet was popular culture. The viral explosion and the jump to Google In October 2006, Google bought Youtube for 1,650 million dollars. Hurley and Chen became Millionaires overnightbut there were many challenges ahead: the platform had to dodge the demands for copyright, maintain community essence and turn attention into money. YouTube was born as a spontaneity showcase. There were no filming sets or careful postproductions: only people recording in their rooms and many others uploading ads, video clips or television fragments. With the arrival of Partner Program In 2007, creators began to professionalize. Someone’s video in front of elephants gave way to an industry of Vlogs, Sketches, Tutorials and Gameplays, many of them already with television quality. The main page of YouTube in January 2006 On Spanish -speaking YouTube, the first years were marked by creativity as free as disorderly. Rubius improvised ‘Epic Vlogs’, Fernanfloo overflowed a very particular humor, Auronplay launched videos recorded in his room talking about games, and Willyrex and Vegetta published their first games of ‘Call of Duty’ and ‘Uncharted‘. The videos were homemade, the Artisanal miniatures And the goal was not to like algorithm, but to have fun. With the passage of time, the rules changed: that spontaneous spirit was left behind, buried by the professionalization and new dynamics of the platforms. In 2012, Vine broke into six second clips. Although it closed in 2017 in the hands of the original Twittersowed the seed of brevity that Tiktok It would end up germinating. YouTube, although it was born with the spontaneity of homemade videos, had to adapt: In 2021 he officially launched Shorts. The evolution of miniatures But the line that separated what is YouTube from what television is blurring. Every day, in addition, more than one billion hours of content on smart televisions are seen. Neal Mohan, Executive Director of YouTube, He did not hesitate to proclaim this year: “YouTube is the new television” And not only because we watch Youtube on TV. Also because traditional televisions are uploading their programs to YouTube. From Disney+, which has published the first episodes of ‘Andor’ on the platformeven chains that already bet fully for uploading their contents to YouTube. Is YouTube the new television? The evolution of YouTube has broken all imaginable barriers. Mrbeastwhich accumulates more than 388 million subscribers, leads a generation of creators who no longer record home videos: They produce blockbusters with film budgets. Beside him, the Sidemen, Mark Rober either Doube Perfect They show how far the professionalization of the platform has arrived. In the Hispanic world, many of the youtubers mentioned above are still present. And we in Xataka have been working on Our YouTube channelalso carrying our essence the audiovisual format. Although traditional television continues to exist, access to content is no longer exclusive. Simply open YouTube to see live newssporting events, entertainment programs or debates in real time, from any device and without fixed schedules. The main streaming platforms have also embraced this transformation: services such as Netflix or Max, for example, already include live broadcasts, sports competitions and news channels. Streaming, which was born as an alternative to linear television, It begins to look more than it seemed to the traditional offer. On YouTube, The amount of ads has increased remarkably in recent yearsand some users have detected increasingly frequent and extensive advertising pauses. Max, meanwhile, He has recovered usual cable television dynamics: content packages, programmed emissions and quality limitations according to the hired plan. The initial promise of absolute freedom is blurred among more classic market strategies. The amount of ads on YouTube has increased remarkably in recent years. To celebrate their first two decades, YouTube has deployed figures that reflect To what extent it has become a colossal platform. Every day more than 20 million videos are uploaded; More than 100 million comments are published; And users click on more than 3.5 billion “Like” daily. More than 300 video clips have exceeded 1,000 million views, a club that does not stop growing. According to similar dataYouTube is the second most visited website in the world, just behind Google, with more than 20 minutes on average per visit and more than 13 pages seen in each session. Two decades after that first video in front of the elephants, YouTube not only stands up: it dominates a good part of the global traffic on the Internet. Twenty years have passed since that first video in front of the elephants. YouTube, today part of the Google ecosystem, is still standing, stronger than ever; But in the world of technology nothing is eternal. Microsoft … Read more
