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

I have run, swim and worked with the Aqua Suunto. Under water I understood what these bone driving headphones propose

A common problem of aquatic headphones is that, in addition to not being Bluetooth for physical reasons, they are usually specifically aquatic. That is, little or nothing appropriate to use them out of water. The rest of sports headphones usually also have something in common: they forget the water. I do not talk about enduring sweat or rain, but really swimming, throwing you into a pool and forgetting everything except to breeze. That’s where the Suunto Aquabone driving headphones that are not only designed to function under water, but They have water as their natural state, But they are still dry in dry. I have tried running, on long walks, even at home while working. But it wasn’t until I took them to swim when I understood what I was trying to do with them. Thus they look when they take them out of our head. Image: Xataka. Its strength is not the sound (because it should not be) The first thing to understand of the Aqua is that they are not headphones to use. They use bone driving, a technology that transmits sound through vibrations that travel through the bones of the skull, specifically the temporal bone, to the inner ear. The auditory channel is free: you don’t need to have anything inside the ear to listen to music or a podcast. That provides a double advantage. On the one hand, comfort and safety outdoors: you can run or bike listening to your content without isolating yourself from the environment. On the other, an even more overwhelming logic underwater: nothing gets into the ear, there is no distorted sound, there is no sense of tamponade. Everything happens in that little transducer that rests on the ear and that, against all prognosis, it manages to keep listening even. That little button that stands out from the transducer is the one that serves to stop or continue the music (a touch), pass from song (two touches) or backward (three touches). Image: Xataka. Pogo load pins that guarantee pond but require their own case. Image: Xataka. And here with the connected load case. This works as an external battery for a pair of complete loads. Connecting a USB-C cable we will move to the wall charger mode. Image: Xataka. The surprising thing is that, despite this different way of transmitting the sound, the experience works. There is no isolation, but it is not what you are looking for here. You can hear the music, the podcasts, whatever you want … and you are still connected to what surrounds you. In water, where any other system fails, they continue to comply. Suunto has adjusted the equalization thinking about that: in outdoor environments and, above all, in immersion. Dry, sound is enough; In pool, better than expected. There are no forceful serious study, but a solid, coherent and much more refined proposal than I imagined. Running and swimming with them Before trying them in the water, I’ve been running with them months. Literally. I immediately noticed that the important thing was not as much the sound quality and the feeling of freedom: nothing inside the ear, nothing that falls out when moving, and the music always present without disconnecting from the world. Ideal to go through the city or by roads without losing sight or hearing what surrounds you. You didn’t have to adjust them every little, or worry about whether they loosen up. They simply worked. Besides, Its three buttons (two on one side, one in the other) allow to change volume or pass song. All great. But although they had convinced me, the best was yet to come. The posterior strip. It is flexible but without applying pressure it remains rigid. I don’t feel that I bounce in my neck. Image: Xataka. The first time I used them in pool I felt a certain astonishment. Not long, but when I did it used to be without music because all the previous solutions had seemed a commitment: they were uncomfortable, unreliable, or directly fragile. In fact it came from using some Sony NW-WS413 –With its humble 4 GB– since 2022. Image: Xataka. With those two buttons under the pogo pins we can do almost any action, combining pulsations, pulsation time, etc. Turn them on, turn them off, adjust volume, enter and exit sports mode, etc. Image: Xataka. With the aqua you do not have to juggle: The placing, you start the session from the headphones themselves (without the mobile, thanks to the 32 GB of internal storage) and throw yourself into the water. From the first length, something changes. Music accompanies you. And you keep swimming the same, without worrying about anything. There are no cables, there are no rubber ones that come out. The band that surrounds the head does not move. It does not loosen. It does not bother. It is as if it were not. But the most interesting comes later. These headphones listen to you swim At the end of the session, the data appears in the Suunto app: Posture, head angle, respiratory frequency, sliding in stroke. Technique metrics that I had never seen in headphones. And that, at least in my case, they told me something I didn’t know: that I breathe badly. Image: Xataka. Or more exactly, that I do it asymmetrically, with my head turning more to one side than to the other. They had never told me in the training. Nor had he noticed it. But there was the graphic. Yes indeed: There is no real -time feedback. What you get is a later readingas if you had a silent coach who takes notes while you swim. It is true that the app could go further in its interpretation of the data – phalta context, lack of concrete orientation – but as a starting point, impresses. It is another way of seeing your body in motion. To listen to you from within. For a future version it would be great to be able to … Read more

The Chandra X-ray Observatory shows us how a neutron star has “fractured a bone” to our galaxy

As if it were the radiography of a broken bone, the last image that has come to us from NASA shows us the image of a whitish structure whose natural silhouette has been “fractured” by the passage of a mysterious object. An object in whose nature we have been able to investigate thanks precisely to the recent observations. The fracture. The new image It was captured Combining captures of different astronomical observatories and shows us the fracture in G359.13142-0.20005 (abbreviated as G359.13) as well as the object that would have caused this fracture: a neutron star or pulsar. The “bone.” G359.13, the “bone” of this photo, is a cosmic structure called sometimes also as “snake.” This cosmic filament expands over about 230 light years and is about 26,000 light years from the earth, near the core of our galaxy. Filaments that emit radio waves that make them detectable from our planet. These structures are directed, NASA explainsby magnetic fields that run in parallel to them. The radio waves that come to us are caused by particles loaded with energy that form spirals along these magnetic fields. Joint work. The image has been possible Thanks to the combination of observations taken in different segments of the electromagnetic spectrum. As we pointed out, the “bone” of the photo is a visible structure in radio lengths, and its observation has been possible thanks to the Radiolescopes of the Merkat Observatory. When “diagnosing” the cause of this fracture, however, resort to X -rays. Those of Chandra Space Observatoryto be more exact. The reason is that the main suspect of causing this fracture is hidden in the structure itself. Fortunately, this mysterious object also emits in the frequency of X -rays, since what is hidden after this “fracture” seems to be a neutron star or, probably, a pulsar. According to NASA, this object would be emitting light both in the form of radio waves and X -ray, to which an additional x -ray source caused by electrons and positrons (its antiparticles) accelerated to large energies should be added. To millions of km/h. The fracture itself would have been caused by the irruption of the pulsar at exorbitant speeds. According to astronomer estimation, this speed would be between 1.6 million and 3.2 million kilometers per hour. A study linked to this image was published last year In an article In the magazine Monthly Notices of the Royal Astronomical Society, Change perspective. The image is a memory that sometimes things are not what they seem. The light that our eyes perceive is a tiny fraction of the emissions that exist in the cosmos. Sometimes the invisible to our eyes can be made visible using the correct instruments, while other times the opaque may not be so much if we change perspective.

The bone of the sardines is an important source of calcium. And it is not the strangest food that this mineral gives us

Calcium is a fundamental element for our body and, especially. Surely we have heard throughout our life (and especially in our childhood) that you have to drink milk to gain calcium For our bones. While milk is far from being the only food capable of nurturing our bones with this mineral. First of all, perhaps it is convenient to explain why we need calcium, because the notion that calcium is good for our bones, although exact, does not give us excessive information either. Fundamental for the formation and maintenance of bones and teeth, calcium is the most abundant mineral in the human body and 99% This is precisely in our bone structure. That is why His lack It can cause problems such as rickets in children and osteoporosis in adults. But calcium also exercises as electrolytea mineral with electric charge that our body uses for various functions. In it Case of calcium Specifically, its presence in muscle cells allows us contract and relax our muscles and transmit signals through the nervous system, in addition to helping blood and hormones circulate through our body. It is difficult to talk about calcium without starting with dairy. These are the foods that we most associate with the element. Milk contains abundant calcium and some of its derivatives contain even more. In a natural yogurt, low in fat (about 125 grams) we can find Approximately 248 milligrams of calcium. Some cheeses contain calcium concentrations that are even superior. However, there are foods that can contribute both calcium and dairy products. Or even more. Some calcium sources can be surprising. We can find abundant calcium in vegetables such as the Brocoli, Kale or Collized, or in the Berza or cabbage. But perhaps the most surprising plant source is another sheet: that of the ortiga. Cooked, this urticating plant can contribute us Around 125 milligrams of calcium per 100 grams of product. Diverse sources Another important calcium source is in fish. We know that calcium in our body is concentrated in the bones, but the bones of other animals also have calcium. Normally we do not consume food with bone, but there are exceptions. For example, the thorns of The sardines. This makes this fish, consumed with bone as we usually do for example when we eat it, be it Another unique calcium source. The drinks that we usually use as an alternative to milk are, curiously, a source of calcium in themselves. The reason is that these are usually made from calcium -rich foods. Soybean is one of them (and therefore also other derivatives such as tofu), but also some nuts such as almonds. Some of these drinks can also be enriched with calcium to strengthen this contribution. In general, we can also find various foods enriched with calcium, including dairy, juices, and flours and their derivatives. We can even find Calcium supplements If we require them. The calcium content of a food is not the only thing that should matter. The reason is that our body does not always absorb all calcium present in these. In the absorption of this mineral, another nutrient plays a fundamental role, the Vitamin d. This micronutrient plays a key role in the absorption of calcium and also phosphorus.

The first bone toolbox

We have been using tools for millions. Does more than three million years, and when the Homo sapiens I was not even on the horizon, sticks were used to those who shape to perform certain tasks. Subsequently, stone tools came to hit, cut or scrape and, more recently, bone. Bone tools were not only more elaborate, but also more versatile to be able to carve them to create more precise ways and The oldest bone tools dated about 500,000 years ago and were found in European deposits, but a new finding has staggered that belief system and rewored one million years. A milestone. Until now, we believed that the Homo sapiens He had the monopoly of the first industry of systematic bone size to create tools, but a team of CSIC researchers (the Higher Council for Scientific Research) has uncovered Something that puts that idea up. It was not half a million years ago when hominids began to systematically create bone tools, but 1.5 million years ago. The key to all this? The finding of the oldest bone toolbox “discovered to date. The toolbox. In a study published in NatureThe team details a set of 27 tools found in the Olduvai throat, in Tanzania. It is the region known as the cradle of humanity due to the numerous archaeological remains of tools that allowed the evolution of civilizations. In the study, researchers comment that before their finding, bone tools were considered episodic and not very representative of the first tools sets Homo. However, so many tools found in the same place exposes a totally different situation: they created them systematically and routinely. Swiss razor. Several of these tools have almond shape, presenting pointed ends, sharp edges and an oval intermediate zone. In statements a The avant -garderesearcher Ignacio de la Torre, from the CSIC History Institute, says they were authentic “Swiss knives” due to their versatility, since they used them “for all kinds of activities: both those that needed a shear edge and those that required a resistant tip.” Chance. The most curious thing is that, like so many times, in the discovery there was something that played a leading role: luck. De la Torre comments that the discovery was casual due. They were investigating the area due to their archaeological wealth when, suddenly, they found a tool. As it was so obvious that it was this type of gadget, they search between the collection of remains they already had and found a pattern. “If you don’t expect to find something, there are many times that you escape, since you are not looking with your eyes appropriate,” says the researcher. And, the result of that chance, we have been able to fill a historical void between the standardized use of stone tools millions of years ago and that of bone tools 500,000 years ago. Perception of animals. Beyond the archaeological importance of the tools themselves, this finding changes the perception we have of the civilizations of that moment. De la Torre comments that, thanks to this discovery, “we can say that humans already had primary access to meat resources” at the beginning of the Achelense period -when the site of the Olduvai throat was formed. For hundreds of thousands of years, hominids saw animals as a danger and a source of food. Also as competition, since they competed in hunting against hyenas and felines. However, De la Torre considers that, with this finding, those hominids no longer saw animals as food, “but also a source of raw materials with which to manufacture tools.” And those found are forged from bones of mammals as large as elephants or hippos. Uploading a civilization. And, of course, access to these tools is a better technology and, therefore, a series of crucial innovations for the evolution of civilization. “By producing technologically and morphologically standardized bone tools, the first Achelenses carver developed technological repertoires that were previously thought to have appeared more than a million years later,” says De la Torre. “This innovation could have had a significant impact on the behavioral and adaptive potential of the first humans, including improvements in their cognitive abilities, technological development and in the acquisition of raw materials,” he adds, pointing out the importance of tools to “upload a step” in civilization. And a mystery. Although the discovery, as researchers point out, is historical, there is an important issue that flies over this finding: it is not known who the toolbox was. The reason is that no human remains have been found together with them, which makes it impossible to identify the culture to which they belonged. It is known that Homo erectus and the Paranthopus Boisei They lived in Olduvai at that time, so it is likely that the box belonged to one of these species and those responsible for their technological development were, but it is something that cannot be assured. At least, of course, right now. The obvious is what we commented: apart from not knowing What species belongedwhat they show is that we start using sophisticated tools a lot, a lot before what was thought.
