Archaeologists have found the bodies of two women embracing in a medieval tomb. Now they are a huge mystery

There are eternal hugs, there are mysterious hugs, there are hugs with so much sentimental charge that only those who melt into them understand them and then there are hugs like that of the two corpses from the Middle Ages. located a few years ago next to Opole Cathedralin southern Poland, which add up to all these characteristics (and some more). When archaeologists discovered their intertwined bodies underground in 2023, they began to ask questions that they hoped to resolve by analyzing DNA samples. They have achieved it… halfway. Experts now better understand who the bodies belonged to, but are even more confused about how to interpret their eternal embrace. In a place in Poland… To understand the mystery you have to go back three years ago, between May 2022 and November 2023when a group of archaeologists began to excavate around the cathedral of Opolea small city in Upper Silesia (Poland) located on the banks of the Oder River. The origins of temple They date back to the 11th century (in the 13th it was expanded thanks to the support of the local nobility) and researchers hoped that their tombs would help them better understand the funerary rituals of the time. In total they discovered 46 burialsalthough there was one in particular that caught his attention: a grave that contained two skeletons, baptized ‘nº31′ and ’32’. What was so special about them? To begin with, his tomb was located in the northern area of ​​the cathedral, near the walls and foundations of the temple. That is relevant in itself because not everyone could hope to have their remains rest in a place like that. When both bodies were buried, in the Middle Ages, the burial areas so close to the consecrated temple and its relics were usually reserved for the most powerful and wealthy people. The bones fell apart 154cm deep and were very deteriorated by the passage of time, which greatly complicated their identification. The reason: they were once deposited in the ground, only with shrouds and on stretchers, so parts of the skeleton have been lost and others are fragmented. An enigmatic position. Although the above is interesting, there was another reason that made archaeologists interested in bodies numbers 31 and 32: their posture. The first skeleton (31) reveals that the body was buried face up, in the position in which the deceased were usually buried. The 32nd, however, was lying on his side, leaning on his side, with one leg half bent and his right arm stretched under his partner’s skull. The composition is as clear in 2026 as it probably was in the 13th century: both corpses they are hugged in a position that denotes intimacy. Add and continue. Those in Opole are not the first centuries-old burial sites in which we have found hugging bodies. In 2007 We saw something similar in Mantua, where archaeologists also discovered the remains of two bodies buried 5,000 years ago in an intertwined position. And that is just one of several examples. We located another one in 2015 in the Peloponnese, where a couple from 3,800 BC was found buried in a similar pose. And what does it mean? The big question. The most logical thing is to assume that the two people buried in Opole maintained such a close relationship that those who survived them believed that it was most appropriate to bury them together, in an intimate position, with their bodies intertwined. The key is… Why? Were they family? Did they have a romantic relationship? It is not a simple question because by asking it from the 21st century we run the risk of trying to answer it with a presentist approachbased on our own vision of the world. The DNA wild card. To clear up unknowns, a group of researchers turned to DNA analysis. Their goal was to subject the bones unearthed next to the Cathedral of the Holy Cross in Opole to an archaeogenetic examination in search of some answers: What age and sex were both deceased? Were they family? Maybe they were father and son, brothers, an uncle and his nephew? The results have just been published in an article published in the magazine Archaeological Science: Reports and they are surprising. Although the bones have degraded and do not allow tooth enamel to be analyzed, a study carried out by experts from the Kiel University Yes, it has revealed three clues. First, the bodies belonged to two people who were around 40 years old. Second, both correspond to women. And third, there was no relationship between them. There is a link, but… what? “Our DNA analysis shows that the two women were not closely related by blood, but genetics cannot tell us how they were socially or emotionally connected,” recognize to The Country Joanna Romeyer-Dherbey, one of the researchers who signed the paper and who highlights how “extraordinary” it is that centuries later archaeogenetics can reveal to us the secrets of two people buried together. If they were not direct relatives, and in view of how they have been found buried, does that mean that the two women from Opole were lovers? Are we looking at a homosexual couple buried together and embracing in the middle of the Middle Ages? Researchers cannot rule it out. Nor affirm it “with confidence”. Theorize yes, but with caution. What your article does insist on is the call for caution: “Archaeologists should avoid projecting modern cultural categories onto past practices when material evidence does not distinguish between multiple plausible explanations.” After all, both women could be lovers, but also friends, relatives without a biological link (through adoption, for example) or even members of the same religious community. To put it another way, what if they had tragically died at the same time and the community decided to bury them together? Are there more clues? Yes. One. and it is fundamental. The bodies have not only appeared in the same grave, in a position that denotes an embrace. … Read more

Science wants to put ‘microrobots’ into our bodies to medicate us. They have already given good results

One of the great problems of modern medicine in the treatment of different human ailments is the “killing flies with cannon” approach. This means that when we have a headache and we take paracetamol, this medicine is distributed throughout the body and not only where it needs to take effect. But this is something that may end up changing thanks to microrobots. The importance. That the medication ‘walks’ throughout the body seems completely irrelevant as long as it has its analgesic effect, but the reality is that it is the responsible for many side effects that are generated. For example, taking a simple ibuprofen to relieve pain or reduce inflammation seems like a wonderful thing. But the fact that it has a general effect on the body also causes the blocking of mucus production in the stomach, which can lead to one of its most ‘famous’ side effects, such as the generation of stomach ulcers when abused. And when we talk about the much more serious side effects, it can cause many clinical trials of new drugs to have to be stopped because of this. But simply with a system that makes the medication act in a specific place in the body, this problem could be alleviated (in part). A new advance. A team of researchers from ETH Zurich has published in the magazine Science a solution that brings us a little closer to the setting of the movie Amazing Journey: a platform of magnetic microrobots ready for clinical use that are capable of traveling through blood vessels and releasing their cargo into the affected tissue. Bradley J. Nelson, co-author of the study and professor of robotics at ETH Zurich, says this is just the beginning: “We’re just the tip of the iceberg. I think surgeons are going to look at this and I’m sure they’ll have a lot of ideas about how to use it.” A simple grain of sand. In this case we are not talking about a metal robot with gears, but rather a capsule of approximately 1.69 mm in diameter that is designed to dissolve inside the body. We can rest assured that we will not have thousands of grains of metal sand in our bloodstream. But to get here, the engineering behind it is not at all simple. One of the challenges, logically, is that its application would be viable within the human body. To do this, the team had to balance three key factors such as: biocompatibility, drug loading capacity and magnetic control. The result was a spherical gelatin matrix that has three components: Iron oxide nanoparticles to respond to magnetic fields. Tantalum: a dense metal that can be ‘seen’ through radiology techniques in order to follow its path through the body. The medication you want to apply. How it moves. In addition to the capsule, what is important is how it moves until it reaches the target where it must act. For this, an electromagnetic navigation system called Navion is used. To do this, coils are placed around the patient’s head to generate a magnetic field around it that allows the capsule to move. In this way, a surgeon, for example, will be able to control the capsule almost as if it were a remote-controlled car to be able to reach the desired action point. To do this, there are different ways of moving through the vessels: by rolling, by dragging or by navigating the blood flow itself. A suicide mission. Once this microrobot reaches its destination, the doctor will be able to activate the final phase. Using high-frequency alternating magnetic fields, the iron nanoparticles inside will heat up, which will cause the gelatin matrix to melt in a matter of 40 seconds, releasing the drug at once. In their tests, they managed to transport rtPA (a powerful drug to dissolve thrombi) to a clot in a vascular model, managing to restore blood flow in less than 20 minutes. When will it reach the hospitals? Although the system is quite promising, it will take time to reach patients. The researcher himself points out that clinical trials could begin within three to five years. In addition to thrombi, applications are being considered to treat aneurysms, arteriovenous malformations and very aggressive types of brain cancer. It’s not the first time. The medicine every time tends more towards personalization of treatments. In cancer we already see it with use of therapies such as CAR-T which focuses on training the immune system to specifically attack a person’s tumor cells and not healthy cells. A completely targeted therapy like the one proposed in this system, but in this case it is applied in the daily clinic (although it has a very high cost). The same happens with the immunotherapy with the use of antibodies. In this case, science looks for those particles that are unique to tumor cells and that are not present in healthy cells. In this way, drug weapons can be created that directly attack cancer cells. In Xataka | The rarest element on Earth aims to cure cancer. And Europe is already accelerating its production
