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

everything we know about the collision between an Iryo and Alvia from Renfe in Adamuz (Córdoba)

On January 18, 2026 at 7:40 p.m., a collision occurred between an Iryo train and an Alvia train in Adamuz (Córdoba) in what is the most serious railway accident in Spain since the derailment of a train in Santiago de Compostela in the area known as the A Grandeira curve. The accident is the first to occur since the high-speed lines were released in our country. When we write these lines, 39 deaths have been recorded but rescue efforts continue. What has happened? On January 18, 2026, an Iryo train that had left Malaga heading to Madrid at 6:40 p.m. derails near the town of Adamuz (Córdoba)once you have passed this stop. The derailment occurs on a straight line and leaves the last three cars of the train off the track. At that moment, an Alvia (Renfe) train traveling in the opposite direction and that had left Madrid bound for Huelva collides violently with the Iryo wagons that were occupying its track. The violence of the crash knocks this last train off the track and ends up at the bottom of an embankment. Emergency services are located on both trains at a distance of 800 meters. Click on the image to go to the originalgal tweet The victims. According to the latest count of deaths and injuries provided by the emergency services to EFE There are 39 deaths and 73 injuries that have required hospitalization. Of them, 25 are seriously injured. In addition, 173 people with minor injuries have been recorded. It is estimated that 100 people were traveling on the Alvia train to Huelva and 317 passengers were traveling on the Iryo train. Renfe has set up a telephone number for family members: 900 10 10 20. Both companies have set up spaces for family care at the Atocha, Seville, and Córdoba stations. Renfe has also set up rooms at the Málaga and Huelva stations for this same purpose. In addition to the regional and municipal emergency health services, the Junta de Andalucía has sent 16 forensic experts and the Military Emergency Unit (UME) has mobilized 37 soldiers and 15 vehicles. Click on the image to go to the original tweet What is known about the accident. At the moment, little and it is expected that the investigations will take time. At a midnight hearingTransport Minister Óscar Puente described the accident as “rare and difficult to explain” as well as “tremendously strange.” The circumstances are still unknown but it is necessary to investigate why the Iryo train left the track on a straight line. At the moment, it is believed that at the time of impact, the Iryo train had reduced its speed but the Alvia was traveling at 200 km/h. Puente has also highlighted that the infrastructure had been recently renovated with an investment of 700 million euros and that the renovation work had been completed in May in the area of ​​the accident. As for the Iryo train, it was “relatively new, practically new that I don’t know if it lasts four years.” They have asked to wait for the accident commission to have more information about what happened. The trains. Iryo is an Italian company which has been operating in Spain since 2022 and whose capital is contributed by Air Nostrum (25%), Globalvía ​​(24%) and the Italian public operator Trenitalia (51%). In Spain they use Hitachi ETR1000 trains also known as Frecciarossa 1000 (red arrows). In his search to replace AVE vehicles, Transport Minister Óscar Puente has shown interest in these vehicles, which are considered among the most modern and advanced in the world. They are manufactured by the Japanese Hitachi in Italy and can move 457 people. They have a maximum approved speed of 380 km/h but in commercial services they do not exceed 360 km/h. In Spain, the maximum speed they can reach is 300 km/h. The Alvia train that collided with Iryo’s vehicle is from the 120 series. These trains have variable gauge capacity and are manufactured by CAF and Alstom. On international gauge roads they can reach 250 km/h and on Iberian gauge they reach 220 km/h. It is believed that at the time of impact it was traveling at 200 km/h. Its capacity varies between 238 and 270 seats.. Click on the image to go to the original tweet Cancellations. At the moment, traffic in the southern high-speed corridor is completely suspended. The emergency services have already warned that the corridor will remain closed throughout the day on Monday. Thus, all services between Madrid-Córdoba and the branches to Seville, Málaga and Huelva are suspended. In addition, services to Cádiz, Algeciras and Granada have also been suspended today. Those affected They can claim the return of the ticketssince the service is not provided.

While we wait for solid-state batteries, the University of Córdoba has an idea for the electric car: human poop

The automotive industry has launched itself into electrification arms. Be with the hybrids, plug-ins either 100% electricthey all have batteries, and the key to convincing more users of make the jump from your combustion car is guarantee greater autonomy. The solid state batteries are one of the technologies in researchbut there are other very promising ones such as lithium-sulfur, and the University of Córdoba believes that there are two secret ingredients to improve the formula. Urine and excrement. Li-S. They are not new. We have been talking about the lithium sulfide batteriesand while we find the economy of scale necessary for solid-state ones to establish themselves, lithium-sulfur ones are one of the hopes for electric cars. They have twice the real energy density of lithium-ion, sulfur is extremely abundant and economical compared to critical materials such as cobalt or nickel, It is not something that China controlsit is safer because the risk of thermal runaway is lower and the environmental impact is reduced. They are not perfect, since the conductivity is low, the manufacturing processes are not as optimized as those of current alternatives and, above all, the current useful life is very limited: although they are moving forward In this sense, just 300-500 charge cycles compared to between 1,000 and 3,000 for lithium-ion batteries. However, as we say, they have become a promising technology, and the University of Córdoba wants one of the ingredients in the battery to be… poop. Batteries from waste. The Chemical Institute for Energy and the Environment, or IQUEMA, of the University of Córdoba has published a study in which they test the potential of sludge from a municipal treatment plant when converting it into activated carbon. It is an essential material for lithium-sulfur batteries, since it works as a conductor, and they consider it to be the answer to the challenge of optimizing the electrodes of these batteries. As we said, sulfur has advantages, but one of the great deficiencies is its conductivity index. This requires active carbon and other conductive matrices that are expensive to produce. But of course, if this conductive matrix is ​​created from waste that all cities in the world produce no matter what, things change. Villaviciosa de Córdoba. To do this, IQUEMA has used sludge from the wastewater station of Villaviciosa de Córdoba. This plant uses a treatment system that generates a sludge with an interesting composition to carry out the experiment: It is rich in organic matter. Also in metals, nitrogen and phosphorus. Combining them can create a material with a good electrochemical performance index. The process is as follows: Drying: the mud is dried and pulverized. Chemical modification: Potash is added as a chemical agent to make the material more porous. Pyrolysis: the mixture is subjected to temperatures of 800º to convert the organic matter into activated carbon. Mixture with sulfur: thus it is trapped in the active carbon matrix and the last step would be to integrate it into the battery electrodes. Promising. The researchers have found that the activated carbon obtained has ideal properties to be used as a material in these batteries. Its porous structure and nitrogen doping improve the transport of electrons and ions, and the resulting material has a high sulfur content. This allows the battery to have great electrochemical stability. That is to say, one of the big problems of this technology, the low conductivity of sulfur for the cathode, is something that mitigates the matrix created from the Villaviciosa de Córdoba sludge. And because its raw material is what it is, it is easier to recycle than other conventional batteries for which you have to develop tadjacent technologies for sustainability. According to the researchers, it is an avenue worth exploring because “triple the storage capacity of a lithium-ion battery”. “It is a great advance that we achieved from a waste that we considered problematic” – IQUEMA researchers Beyond the poop. Considering the results, it is likely that we will see more studies in the same direction. It is something that solves a double problem: the municipal waste management by converting it into a key material to solve one of the challenges of lithium-sulfur batteries. And the interesting thing is that IQUEMA has not remained only in the sludge of the sewage treatment plant. Previously explored the potential of agroindustrial byproductslike the olive pits and avocados, but also almond and pistachio shells. The problem is that these materials are already in demand in other sectors (such as composting or heating), and that is where the great advantage of human excrement lies: “no one” wants them.

Planting the heat of Córdoba in summer is impossible. I have tried a personal thermal dissipator to at least try

I do not discover anything to anyone if I say that In Córdoba it is hotter than on Charmander’s birthday. We have many good and beautiful things, such as the Mosque-Catedral, Medina Azahara or the Alcazar of the Christian Kings. This is the only city in the world with four assets of humanity, The first person to fly did in Córdoba And for having, we have even A traffic light with artificial intelligence. But if there is something we have and that we are left over, it is, without a doubt, heat. There are those who fight this excess of Celsius degrees leaving Fuengirola (also called Córdoba II). Others put in front of the fanunder the air conditioning or call the friend who has a pool at home with the excuse of “how long without seeing us.” I, for my part, have tried in a less conventional way. I have done it with a personal thermal dissipator of Sony: the Reon Pocket Pro. It is put below the shirt, but so you can see the size better and where it should be placed | Image: Xataka Terus dissipator … what? I know it sounds a bit strange (not as much as Go to the gym with an exoskeletonwhich also made), so we go in parts. The Sony Reon Pocket Pro is a portable thermal device that cools and heats the part of the body with which it comes into contact. That part is precisely the upper back area, just below the neck. It is not a portable air conditioning, much less. How does it work? The device incorporates two independent thermal modules in the rear that cool or heat according to the context (then we return to this) and a fan that extracts the heat from our body and expels it above. The two thermal plates alternate, so that when one reaches a certain temperature, the other is deactivated and activated so that the sensation of freshness is constant. These two plates work independently and cool or heat | Image: Xataka How do you get? We have to place it so that the two plates touch our body and the upper air exit protrudes slightly from the shirt. If we wear a shirt, we can use the adapter. The device is slightly curved, thus respecting our natural curve, and has a pair of flexible tubes that are placed around the neck and keep it subject. These, by the way, are not seen, but they stay under the shirt. And yes, they are noticed. The air exit should stay above the neck of the shirt | Image: Xataka These moorings should also be placed below the shirt | Image: Xataka Is it comfortable? Depends. It is acceptable if we take it while we walk or We are perfectly seated (With a straight back), and that weighs about 200 grams. If we change posture, for example, more reclined in the chair or lying on the couch, impossible. As for noise, I have not appreciated that the fan makes more account noise. I wear it right now and in my office, where only the noise of my mechanical keyboard is heard, I do not appreciate it in excess. However, I must say that it seems like a device too large and that finding the exact location in which it must be placed is complicated. It is not so “of remove and put” as perhaps you could expect a device like this, but you have to place it well, in its place, if we want it to work correctly. That it is more or less comfortable will depend, in large part, on the position we adopt | Image: Xataka Ok, but it cools? Let’s go to the point. The Reon Pocket Pro can be used in two ways: manual or automatic. If we establish it in manual, we can configure (via buttons or via app) the target temperature and the device will be in charge of reaching it. If we establish it in automatic, it will use, in addition to the data of the device itself, those of the Reon Pocket Tag to determine the objective temperature depending on the ambient temperature, the humidity and even the exposure to direct light. The problem is that this small sensor works well if it is abroad. If we carry it in the pocket (it is fully designed to hang it on the keys or in the pants), the data can vary. In any case, it works well and if we are going to use it in a room like an office for a while, just leave it on the table and forget about it. Reon pocket tag | Image: Xataka As for the sensation, it is … curious. As soon as we put it, we will notice how the surface of the neck begins to cool (or heat). It is almost instantaneous. With the passage of the latter, the sensation of freshness is improving and, thanks to the two thermal modules that are alternating, it is constant. And yes, cool. Now, the reality is that the one that is: the sensation of freshness, within that it relieves even going down the street, is very localized in the area near the location of the device. The cold mode sensation is the same as if you carry a bag of ice cubes on the back. In heat mode, it reminds me a lot of thermal blankets for neck pain. Image | Xataka On the battery. Using it at a medium cold temperature, the device lasts practically one day. A working day endures it without problem. At a lower or greater temperature, depending on the way we choose, less autonomy. In that sense, the use of hot mode spends more than cold mode, but for obvious reasons I have not used it just during these days. As for the load, it is completed in approximately three hours. So… Is it pleasant? It is, especially when you put it … Read more

Córdoba has been trying to finish a road for 20 years. Now they have encountered a problem: Ruins Mozárabes

Doing works in a city like Córdoba is a risk task. From time to time, in Spanish cities we find new vestiges of previous eras. An example is the ruins under the door of the sun or the Otero orchard deposit in Mérida. Córdoba is another level and, during preventive excavations under the layout of a future and important road, they have found new Christian ruins. They are not just a few more archaeological remains: this finding provides unique context to the coexistence between Christians and Muslims in Islamic Cordoba. Short. The northern round of Córdoba will be the road that It will close The city ring. It is a complex project that has been carried out in phases and that has been controversial Due to neighborhood complaints motivated by noise that will generate the increase in traffic. During preventive excavations, and how we read in Cordopolisthey found something that will further delay the project: a set of structures that date back to the seventh century. And the date is relevant because it would contribute new context to the Córdoba of those first decades of Islamic domination. By layers. Córdoba is a large city, but the Islamic Córdoba was even greater. With the passing of the centuries, the city was diminishing due to the new urban projects, which were building on the remains of the past. Mosque itself is an example of that construction in phases and, although in an exaggerated way, of that building on the above. When it is excavated to do works, it is not uncommon to run with remains of Islamic neighborhoods, but the interesting thing about this new finding is the cult difference: the Christian. A cult that, due to the progressive Islamization from the city, he left displacing towards the most peripheral areas. The remains. In Cordopolis, Alberto León, professor of archeology at the University of Córdoba, comments that there was a record of the destruction of Christian temples at the dawn of the seventh century. Subsequently, Abderramán’s “pact” was allowed, allowing the coexistence of the cults. The problem is that no remains of those constructions made by the Mozarabic. That is why the complex discovered under the future North round Be so relevant. Presents Tapial walls (clayey earth compacted with blows) and a pool of about 50 meters. Archaeologists have been inspecting the place since the end of last year, and it is now when they point out that it would be a monastic building, probably divided into areas for men and women, with clarifying columns arranged, as you can see in the photosaround a patio and that the pool could be a baptistery. The lost basilica. Ángel Ventura is a professor at the University of Córdoba and one of those who is inspecting this monastic complex. In Córdoba newspaper He launched the hypothesis that the ruins could belong to a possible basilica in honor of Santa Eulalia de Mérida. It was a martyr that had great importance for the Cult in the city And there were documents that implied the existence of “their” basilica, but without having been found. Clue. In the end, this discovery will allow to have more context about the coexistence between Christians and Muslims, but it is also relevant because, according to Alberto León, “is one of the two examples of existence of a Christian cult complex in Islamic neighborhoods.” The researchers continue to study the place to determine their function, chronology, when it was abandoned and launch hypothesis about the coexistence between the different cultures of the city. What is clear is that there had to be many more like this in the suburbs, so future excavations could even show more context about that peculiar era of religious coexistence in the Islamic Córdoba. And also that it would be necessary delay or even rethink the work of the road to be able to study this important finding.
