Science finally shows that they hunted the largest beasts of their time

by

The classic image of neanderthal as a brute hominid with no intelligence and that barely survived by scavenging what other predators left behind, it is increasingly being left behind as we make new discoveries. Precisely, we now know that 125,000 years ago, our evolutionary cousins They were Europe’s apex predators, capable of organizing to take down the most formidable land creature of their time: the straight-tusked elephant. A beast that doubled the size of today’s African elephants and reached 13 tons in weight. The mystery of the spear. To reach this conclusion we have not traveled back in time, but rather we have gone to Leringen in Germany. Here in 1948 archaeologists found a skeleton of the straight-tusked elephant, with a 2.4 meter yew spear stuck between the ribs. A priori it seemed like the definitive proof or, as some anthropologists have called it, the smoking gun of Neanderthal hunting. However, scientific skepticism prevailed: was it a coordinated attack or did a group of opportunistic Neanderthals find an elephant trapped in the mud and finish it off? This is where a great debate has been generated that has now been closed in 2026 with the publication of a new scientific article. What have they done? Here the researchers have basically focused on the skeletal remains of the animal that was found, and the objective was to find the details of the hunting process. What they saw was that the cut marks and damage to the bones did not correspond to a simple opportunistic shot, but to a frontal and tactical attack. In this way, experts point out that the Lehringen spear is no longer an anomaly or a happy coincidence, but rather irrefutable proof of systematic hunting behavior. The context. In addition to what has now been known, in the past researchers demonstrated that the hunt for these titans was not an isolated event, but rather a systematic and recurring practice. The problem that was seen is that shooting down a 13-ton elephant raises the obvious question: what do you do with so much meat before it rots? This is where the classic perception of the Neanderthal falls apart. An elephant of that size provided enough calories to feed 100 people for a month, and processing that amount of meat and fat required three basic points: Groups of people larger than previously believed, which break with the idea of ​​small nomadic bands of 20 individuals. Settle in a specific area when you have plenty of food. Master fire and techniques, such as drying meat so that it can last for a long time. A new image. With all this research, the truth is that the textbooks have to be rewritten, since you can see how Neanderthals had the cognitive ability to plan, the communication necessary to coordinate mass ambushes, and the social structure to process and store tons of food.

Sam Altman has had another great idea to finally charge the user all the money he needs: a receipt at the end of the month

by

We are used to pay the electricity bill or water because they have become basic and totally universal goods. Well, Sam Altman, CEO of OpenAI, is clear that artificial intelligence will be exactly that: a commoditya basic and totally universal good. This implies, of course, that there will come a time when, just as we pay the electricity or water bill, we will pay the monthly AI bill. Paying for AI will be an everyday thing. Altman recently participated in an event in Washington DC and there raised an idea that has been around for a long time but is certainly gaining more and more strength: that AI will offer like electricity or water, on demand: as soon as you need it, it will be there for you. That, of course, will mean that just as we now pay for our electricity or water use, we will also pay for the AI ​​supply that we use. And we will do it at the end of the month with the traditional method: an invoice from our supplier. In Xataka The most powerful AI agent in the world has just arrived: the first thing it does is warn you that it is dangerous From consuming kW to consuming tokens. Thus, instead of paying fixed subscriptions as we usually do now when contracting ChatGPT Plus or Claude Pro, for example, what we will do is pay that monthly bill. The amount we will pay will be based on how many “tokens“(processing units) we have consumed to solve all types of tasks. We have power plants, we will have data centers. To Altman this speech fits like a glovebecause it justifies its AI data center megaprojects —and those of the rest of the industry—. If AI is to become that universal basic resource, we will have to have the infrastructure (the “AI power plants”) to sustain it. Without such infrastructure, Altman warns, the price of “intelligence” will skyrocket, turning it into an exclusive privilege for the richest or a resource rationed by governments. Compute Yottaflops. That race for infrastructure has already begun, and big technology companies are fueling it. The reason is simple: either they enter that maelstrom or they risk being left out if the AI ​​revolution actually becomes a reality. Lisa Su, CEO of AMD, explained in her opening talk at CES 2026 that the world will need more than “10 yottaflops” of computing – 10,000 times more than the existing AI capacity in 2022 – in the next five years to be able to meet the demand posed by this massive use of AI. Chips missing… and a lot of energy. The real obstacle to achieving such computing capacity not only lies in the chips – the memory crisis is a side effect of this – but also in energy. data centers they consume a lotwhich makes national electrical networks can finish not having sufficient capacity to supply said energy. OpenAI will not stop spending. Greg Brockman, president of OpenAI, explained in December that their projects, no matter how gigantic they may seem, will go further. Although the company has already committed to investing $1.4 trillion with its partners in data centers over the next eight years, OpenAI wants to “get ahead of the future, but I don’t think we can be, no matter how ambitious we want to dream of being right now.” That is to say, he believes that all his estimates and projects may end up being dwarfed by the true scale to which AI can reach. {“videoId”:”xa1wtpm”,”autoplay”:false,”title”:”Perplexity, Personal Computer”, “tag”:””, “duration”:”88″} Big Tech wants to bill you at the end of the month. Turn AI into a commodity For it to reach all homes would be an absolute triumph for the companies that are investing in it. The tech industry has not managed to direct its costs to the user other than in things like our internet connection or, at most, in our spending on streaming services —similar to current AI plans—. If it achieves that bill at the end of the month that hundreds (perhaps thousands) of millions of people would also pay, AI would become an extraordinary income machine.

We have not understood for decades why chronic pain punishes women more. Finally we have the answer

by

Historically, medicine has grappled with an undeniable gender gap in which women Women suffer chronic pain more frequently than men, and on top of that their pain flares for much longer. This is something that many doctors have considered ‘normal’ and has been dismissed with psychological biases. But now science has seen that an explanation should not be sought in the mind, but in the immune system. Against pain. This is the objective that medicine has right now, since it is undoubtedly a situation that for many people can be unbearable. That is why the magazine Science Immunology publish now a new study that offers a paradigm shift in our understanding of the biology of pain. The result of this is that he has managed to find the key to some types of white blood cells called monocytes and in its direct relationship with testosterone. What’s happening? When an injury is suffered, such as a blow, the body tries to defend itself with an inflammatory response. One of its components is pain, which is a necessary alarm signal to warn that something is wrong, but once the tissue begins to heal, it is logical that this alarm goes off. But this is where the body’s defense cells come in, monocytes, which act as ‘firefighters’ by releasing proteins called interleukin-10. Here the research team has been able to see that this interleukin-10, abbreviated as IL-10, acts directly on sensory neurons to “turn off” hypersensitivity and therefore pain. The problem, and here lies the importance between sexes, is that men resolve this inflammatory pain much faster because they produce a greater amount of this protein. The reason. Testosterone. This male sex hormone stimulates monocytes to produce higher levels of IL-10 after injury, and therefore pain can be better reduced. But in women this level of testosterone is much lower, and therefore the production of this natural ‘painkiller’ is lower, which causes the sensory neurons to take much longer to stop giving the signal that generates pain. Your demonstration. Beyond doing so in animal models, the research team has been able to validate the experiments with human data from the AURORA studiowhich is a project that evaluates patients who have suffered traffic accidents and severe trauma. Here the clinical data confirmed the laboratory’s suspicions, since they saw that the elimination or reduction of IL-10 activity in monocytes significantly delays the resolution of pain in both sexes, validating that this hormone-mediated immunological difference is exactly the same in humans. In the future. This discovery is not just another biological curiosity to close a historical debate, but it has important therapeutic implications. And right now the severe pain crisis has to be treated with opiates on many occasions, which have a long list of side effects. But upon discovering this cellular mechanism, the researchers tried administering Resolvin D1a compound that promotes the resolution of inflammation. Here it was clearly seen how pain was reduced equally in both sexes. This is why we are at the gateway to a new generation of non-opioid therapies that specifically modulate the immune system. But what is most important about this study is that it highlights the need to leave behind the “one size fits all” model in medicine to move towards more personalized medicine.

Tecno has finally seen a future for the old modular dream

by

Being able to update the phone without having to change it for a new one is the dream of many of us who love telephony. Throughout history there were several brands that tried it, such as Motorola: Project Ara to the commercial materialization of that format, the Moto Z and its Moto Mods. Currently, one of the manufacturers that has most opted for modularity It’s Fairphone. Now, Tecno has decided to skip what is established and take that dream one step further. Although with a difference from the original Ara: Tecno proposes a magnetic, not structural, modularity. Techno It is not a manufacturer that we know in Europe for its smartphones. Even so, it is one of the brands that the more it grows in share and distribution at a global level. Despite having a clear orientation towards accessible mobile phones, Tecno is characterized by being one of the most innovative and risky. Apart from those two adjectives, there is a third that occurred to me while holding the modular mobile: surprising. But can you still add more things? There are LEGO boxes that have fewer pieces than this mobile When I approached the Tecno stand, and saw all the phone pieces scattered on the table, I thought about the LEGOs I had when I was little and how I was combining the parts to make new figures. What Tecno brought to MWC is more or less the same, at least in essence. The base is an extremely thin phone that features a small camera module in the upper area. Tecno has provided all the components with a good number of magnets, it surely used up the store’s stock. Because everything comes together through magnetism. You can add a telephoto camera module by simply “gluing” this piece to the base lens, for example. Everything fits into place with magnets, just like the external battery module, microphone, speaker… Or the SLR camera accessory. When asked how many modules you can put on the phone at most, Tecno said: “Yes.” I have not put the parallel with LEGO at random: the phone supports a good number of pieces on top. Furthermore, there is another important point: The modules can also be combined without having the base telephone. And they work independently You can put a clip on the microphone and use it as a tie microphone. The same for the speaker, for example. Or use the stand to support the pieces outside the mobile. Everything is anchored by magnetism and in its place. With the drawback that it has to be placed correctly the first time, the system does not offer a visual guide to know how to build the LEGO. An idea that seems extravagant and yet works Modular mobile phones were already invented. And Tecno has come to give the concept a twist to take it to the extreme. Because the mobile works, the parts make sense, the entire concept transcends experimentation to become a product that could be viable. Wow, I could totally buy it. The pieces are solid and well thought out, it shows that Tecno has designed each component with precision. And maturity. Now, it’s not perfect, because the pieces can come apart somewhat easily. The magnetic anchor is strong, but it is still that: magnetic. If the camera gets caught in your pocket, it gets left behind. And if the modular phone falls to the ground… Instead of a phone you have a puzzle. Still far from being able to be bought It is beautiful, it is impressive and it appears solid beyond doubt due to the magnetic union between the pieces. Even so, it probably won’t see the light of day in the near future. Tecno is characterized by experiments, by trying to make smartphones show a different face. Many of their concepts end up as a hook to attract the real catalog, the one that really works. I thought that modular mobile phones, as designed by Motorola with Project Ara, would have no future. Tecno has shown me the opposite: apart from being feasible, with a little imagination you can achieve use cases that no one imagined before. That something like this is so refreshing says more about the current stagnation of the smartphone than about modular phones themselves.

China spent 10 billion on oil it did not need. With Hormuz blocked, the puzzle finally makes sense

by

As the West panics over the possibility of the barrel break the $100 barrieran eerie calm reigns in Beijing. The Asian giant observes the crisis with the coldness of someone who has already done his homework. During the last few months, the world has been debating the excess oil supply, but the real winner of this war crisis is not firing missiles, but has been filling its storage tanks for years in the most absolute silence. World geopolitics has been blown up a few weeks before the expected summit between Donald Trump and Xi Jinping. As reported Nikkei Asiathe coordinated airstrikes of the United States and Israel (dubbed “Operation Epic Fury“) have culminated in the assassination of the Iranian supreme leader, Ayatollah Ali Khamenei. Tehran’s response has been a rain of missiles and drones on American allies in the region. The immediate impact has been felt in the water. The Strait of Hormuz, through which 20 million barrels a day flow (20% of the world’s oil supply), is blocked de facto. As detailed Bloomberg, Rates to hire a supertanker on the route from the Middle East to China have skyrocketed by 600%, reaching $200,000 a day (or 525 Worldscale points for a Suezmax). Besides, France 24 points out that insurers They have increased war risk premiums between 25% and 50%. As reported cnnBrent crude oil jumped 6.5% in the early stages, touching $82, driven by fear of prolonged logistical disruptions. Bob McNally, president of Rapidan Energy Group, warned the US chain that closing Hormuz would cause an immediate global energy crisis. China’s exposed vulnerability On paper, the Donald Trump administration’s offensive should be an absolute nightmare for Xi Jinping. As explained The TelegraphAmerican military adventurism is exposing the gigantic energy vulnerability of China, the largest oil importer in the world, which buys three-quarters of the crude oil it consumes abroad. Washington’s strategy seems clear: suffocate the “rebellious” suppliers that supply the Chinese industrial machinery at bargain prices. Earlier this year, the military capture of Nicolás Maduro has established what some analysts They already call the “Donroe Doctrine”. Trump has been explicit in his goal to control oil. If the United States manages to add Venezuelan production to that of Guyana and its own, it would de facto control 30% of the world’s reserves, according to JP Morgan. This movement cuts supply to China in the bud, evaporating imports that represented around 4% of its maritime purchases. according to data from Kpler collected by The Financial Review. However, Washington’s optimism collides with geology: the infrastructure is so in ruins that loading a supertanker today takes five days and the crude oil arrives so “dirty” that the Chinese and Indian refineries themselves have canceled orders, according to a Reuters investigation. Refloating this industry will cost 10 billion dollars annually for a decade, as Francisco Monaldi calculatesdirector of energy policy at Rice University. For its part, the current blow to Iran. From Chosun Daily details that China bought 80% of Iranian maritime exports last year (about 1.38 million barrels per day), which represents 13.4% of Beijing’s total maritime crude oil imports. As he points out Institute for Energy Research (IER) United States, cited by the same mediumChina has used the heavily sanctioned and cheap oil from these countries to cement its manufacturing competitiveness. Losing Iran and Venezuela would force Chinese refiners — especially the independent ones in Shandong, known as “teapots” — to look for much more expensive substitutes on the open market, threatening to import inflation and slow their economic growth. The master plan in execution If Western analysts expected to see China cornered, they were wrong. Beijing foresaw this scenario of isolation and has been executing a four-pronged master plan for years that today allows it to cushion the blow of Hormuz. While in 2025 the world feared a global oversupply, China dedicated itself to massive purchasing. Last year, China spent $10 billion buying an extra 150 million barrels that it didn’t immediately need, absorbing more than 90% of crude oil storage measurable globally. Supported by a new Energy Law that obliges the public and private sector to maintain reserves, Beijing today has strategic reserves equivalent to at least 96 days of imports, according to The Telegraph. Under the banner of national security, China is investing $80 billion annually in its state oil fields. In March 2025 they reached a production peak of 4.6 million barrels per day and they completed the drilling of the deepest oil well in Asia (10,910 meters). Its goal is not financial profitability, but pure autonomy. With Iran and Venezuela under fire, China has simply turned its head toward Russia and Saudi Arabia. According to oil price, Chinese refineries are absorbing record amounts of Russian crude oil (more than 2 million barrels per day in February 2026), taking advantage of the fact that India has given in to pressure from the US to stop buying from Moscow. Simultaneously, Saudi Arabia has cut the official price of its crude oil Arab Light to five-year lows to gain market share in Asia, which has led China to order between 56 and 57 million Saudi barrels by March. China’s definitive move is to abandon the oil board. As analyzed by Professor Hussein Dia in The ConversationChina’s massive commitment to electric vehicles (50% of new car sales last year) and renewable energy is a national security policy. How they collect in The Telegraph, The new five-year plan (2026-2030) seeks to peak oil consumption by accelerating the installation of solar and wind parks (430 gigawatts added last year alone). Unlike the ships in Hormuz, sunlight cannot be blocked by the US Fifth Fleet. The diplomacy of silence and the illusion of OPEC+ In the face of Khamenei’s assassination, the response of the Chinese Foreign Ministry has been one of calculated coldness. They condemned the act as “unacceptable” and a “violation of sovereignty,” but, as pointed out Chosun Dailythey carefully avoided directly mentioning Donald Trump. From Nikkei Asia explains this pragmatism: … Read more

I am a paddle tennis player and finally a smart watch brand has remembered me

by

I have carried a paddle tennis racket in my hand since I was little. I am worse than hunger, I am not hiding, but I like this sport and I must admit that I look with envy at the fans of, for example, golf or the running. As a lover of smart watches, I have always seen from afar manufacturers launch specific models and functions for runners and golf players with cool metrics, interesting analyzes and specific functions: yes, 3D courses, yes, footfall analysis, yes, that niche data that only the pros care about… And meanwhile, the padel players we were still thereusing the “tennis” mode that tells us little or nothing or, if available, the “paddle” mode that also does not give information about performance in the match. That’s why, walking through the halls of the Mobile World Congress, I couldn’t help but stop at the Mibro stand. Because? Because their watches have a paddle mode, but a useful one with relevant information for players of this sport. Yes, we really exist. Padel mode in the Mibro GS Explorer S-Ti | Image: Xataka My what? Mibro, “your brother in sport”, as one of the company’s workers at the stand tells me with a laugh. Mibro is a company of Zhenshi Information Technology, a Chinese company founded in 2015 with financing from Xiaomi and Nokia. The company specializes in sports wearables and has found a way to increase its presence in the European market in paddle tennis. In fact, they openly recognize it: it is not that padel is gaining traction in China, it is that they know that it is important in Europe and they believe they have a way to differentiate themselves there. And what do they offer? The company has a catalog of watches with a rather high-mid-range price. The most expensive model is the Mibro GS Explorer Swhich costs 349.99 euros and is made of titanium (it is the one in the photos and I must admit that it feels scary, although I would change the strap, which looks very good, for a silicone one for sports). However, it has cheaper models, such as the GS Active2which remains below 100 euros. The operating system is Mibro Galaxy OS 2.0, a very fancy to call an RTOS system that is very reminiscent of Huawei’s HarmonyOS. An example of the metrics associated with paddle tennis | Image: Xataka But let’s talk about padel. The key to these watches, and the reason why they have caught my attention, is because of their paddle tennis analysis. For the uninitiated, in paddle tennis there are different shots: forehand, backhand, volleys, spikes, layups, lobs, drop shots, etc. Understanding well which shots you are doing the most and why can help you understand a match and discover your areas for improvement. For example: if you have lost a match in which you have made many layups (cut, high and deep shot to keep the net), you may have to work on the volley and the force you apply when hitting, because they have been constantly knocking you out of the net with lobs (high and deep balls). If you have made many lobs and few volleys, layups or shots, it is probably because they have managed to keep you down and have not let you go up to the net to attack. Analysis of forehands and backhands | Image: Xataka And that’s where Mibro comes in.. As they have shown us at the stand, the watch is capable of detecting the number and percentage of each of the shots we make in a match. The watch allows us to know how many backhands, drives, layups, spikes, forehand and backhand lobs and forehand and backhand drop shots we have made and, for example, manually cross-check them with our heart rate to see which points have put us in trouble. Example of analysis of blows | Image: Xataka Speed ​​of blows | Image: Xataka It also counts calories and, even more importantly, the speed of the strokes. Although it is easy to associate paddle tennis with strong and very loud hits, the truth is that playing slowly is usually much more effective against players… nervous, let’s say. A weak ball to the side wall will probably do more damage than a strong shot or volley, in the same way that a layup does not necessarily have to be very fast. Knowing that information that, until now, we could not know, can be useful to focus training or take action. To recognize hits, the device is based on a six-axis accelerometer and intelligent algorithms, as is already done in many other watches and many other sports. How does it work? Unfortunately, and although we always want a padel, we have not had the opportunity to pick up the racket and throw some balls in the halls of the MWC, but the fact that it exists is already progress. Counting layups and shots | Image: Xataka An ideal world. At the expense of testing the watch in a real match situation, a function that would make a lot of sense (even via AI) is to be able to cross-reference the heart rate with the shot you have made or with the duration of the points, as well as the number of shots. That would allow us to see at what level of intensity we start to make mistakes, what shots we make when we are tired (perhaps we abuse the shot or miss more layups). The higher the intensity, the more the technique is distorted, and that causes errors. That type of information, well interpreted, is valuable if you are looking to train and improve.

If you have 400,000 euros you can finally fulfill the dream of owning your own island. The problem is how to get to it.

by

If you like nature, spend hours listening to the birds singing and the rustling of the waves, in Welsh you have a unique opportunity. There, in the Dwyryd estuary, a private island with a charming Victorian mansion is for sale for about what it costs an apartment in the center of Madrid. For around £350,000 you can become the new owner of Ynys Gifftana seven-hectare tidal island with a history connecting it to the Stuart lineage. Of course, the offer has a trick. In a place in Wales… More specifically in the Dwyryd estuary, very close to Portmeirion (Gwynedd), hides a curious island that has just gone up for sale. What is ‘curious’ is not only because of its remote nature, its surroundings or the fact that on its entire surface, of 7.2 hectares, there is a single stone construction. What is really striking is its nature. Ynys Gifftan is a tidal islanda portion of land connected to the rest of North Wales by a spit of land that emerges at low tide and disappears at high tide. Hence, access is not easy and, depending on the time, it must be reached by boat or on foot. Landowner for €400,000. For a few weeks now, the island has added one more peculiarity. The real estate firm Carter Jonas inform that it is for sale for a “guide price” of 350,000 pounds, equivalent to 400,500 euros. The price attracts attention in Spain and even more so in the United Kingdom, where it is not far from what an average home costs. In fact, it is much less than what someone who wants to buy a house in the capital must spend. A few days ago the BBC I remembered that those 350,000 pounds exceed the average house price in the country by just 50,000. If we focus on London, the average price for the last year marks just over 600,000 pounds (£656,694), making getting the Welsh island considerably cheaper. A golden opportunity? More or less. Owning a quiet Welsh island for almost half the price of a house in London sounds good, but Ynys Gifftan has several handicaps that recognize the agency itself. To begin its construction, a country house built with stone is not going through its best moment. “It needs a comprehensive reform,” notes Carter Jonaswhich remembers that the house is divided into two floors and has several living rooms, bedrooms and pantry. Annex has a tool shed. Good landscape, bad services. The truth is that the island takes decades empty and those who embark on the adventure of repopulating it will have to face a series of challenges, beyond renovating the house: there is no electrical connection, the water network channeling dates back to the 80s and the current owners of the land do not guarantee that it is still active. In addition, the drainage system is private. As for the rest of the 17.7-acre (approximately 7.2 hectares) island, it is now partially covered by weeds, almost reaching the house itself. From Jonas they slip that part of the island could be dedicated to grazing. The great challenge. Ynys Gifftan has, however, another more important handicap that any buyer should be aware of. Its inhabitants cannot happily leave and enter the island. Not at least how they want and when they want. During high tide a boat is needed to access the island. When the tide goes out, the way in and out is different: with a short walk along the stretch of land that is exposed. With a walk you reach the continent and from there you can travel to Harlecha town of around 1,600 inhabitants where you will find basic services, such as shops, restaurants or pharmacies. Nature… and history. The future owner of Ynys Gifftan will be able to boast of having an unusual property. To start with its location, in the heart of Eryri National Park (Snowdonia). Second, for his story. Its name, “gift island” in Welsh, is said to be a nod to the island’s past, which was a gift from Queen Anne to Lord Harlech’s ancestors in the 19th century. XVIII.

South Korea has had the most catastrophic birth rate in the world for years. And now it has finally managed to grow

by

For a few years now, talking about demographics in South Korea has made it necessary to first take out a clinex package. Despite all his attempts (and there have been not a few) the country seemed condemned to suffer an uncontrollable ‘bleed’ of birth rates and see the seams of its economy tighten. It may sound exaggerated, but it is good to remember that he said goodbye to 2024 by declaring “super aged” and that there are academics who warn that the nation is emptying (literally). With that backdrop, Seoul has started 2026 with a positive fact: wins babies. And it also does so for the second consecutive year. The big question that arises now is… Are we facing a change in trend or just a mirage? The figure: 254,457. It is provisional data (the definitio will not arrive until the summer), but even so it has arrived like manna in a country accustomed to every piece of news about demographics involving a national drama. Last year South Korea registered 254,457 birthsa good balance no matter where you look at it. To begin with because it means 6.8% more that in 2024 and leaves the largest percentage increase since 2007; but those are only two of the possible readings. More babies per woman. Another interesting reading is the one that tells us about the “fertility rate”, the average number of babies that (at a statistical level) a woman is expected to have throughout her reproductive life. A few years ago that indicator plummeted to 0.72very far from the “replacement rate” (2.1 children per woman) that allows societies to remain stable. The data is still below that red line, but at least it has grown: in 2025 it passed from 0.75 to 0.8. Not only that. Reuters remember that the South Korean Government had optimistic estimates that suggested that this rate would grow to 0.75 in 2025 and 0.8 in 2026, which appears to be recovering positions faster than expected. In Seoul the trend is even more pronounced. There the indicator rose 8.9%, going from 0.53 to 0.63. The data is still very poor and they are far away to solve the problem that Korea has, but they suggest a change of cycle. Breaking the bad streak. That the birth rate is increasing in South Korea is news, but it is even more so if (as is the case) that growth is maintained for two years. In 2024 the country has already registered a positive fact (breaking up with eight exercises of consecutive falls) that now invites us to think about whether it has really found the right way to encourage its young people to have more offspring. Of course, the country has invested time, efforts and especially economic resources in that objective, in which it is played from the social sustainability and the march of his industry to issues as relevant as national defense. More weddings, more babies. 2025 has not only been a good year in maternity hospitals. It has also been for the wedding planners. Marriages increased by 8.1% in 2025, reinforcing the 14.8% rebound already recorded in 2024. This is good news because, in a conservative society like South Korea (the percentage of births outside of marriage It’s surprisingly low.), weddings are often considered an early indicator of a rebound in birth rates. Trend or mirage? That’s the million dollar question. That South Korea has been trying to activate its birth rate for years is undeniable, as is the fact that it has invested large resources in this effort and that they have been involved in the effort since the public institutions to the business world. However, there are other factors at play that suggest that the recent growth in the South Korean birth rate could be more circumstantial than structural. That is to say, in reality we would be facing a kind of demographic ‘mirage’. The hangover of the pandemic. When explaining the phenomenon, there are those who point to the influence of the pandemic. Not so much in the birth rate itself as in marriages. It is true that more South Koreans are getting tired and that this indicator will probably influence the birth rate in the coming years, but it is also true that many couples had to postpone their plans during the pandemic. “The number of marriages has increased for 21 consecutive months, from April 2024 to December last year, as couples who had delayed their marriages due to COVID-19 have tied the knot,” recognize Park Hyun-jung, director of the government office that analyzes population trends. He himself admits that today it is very difficult to establish a clear “correlation” between government policies and improved birth rates. A demographic with ‘echo’. There are those who point out, however, another factor that would be directly influencing South Korean demographics: history. The explanation I broke it down Rapahel Rashid recently in Guardian and provides an alternative theory. More babies have been born in the South Korea of ​​2024 or 2025 simply because the same thing already happened in the Korea of ​​30 years ago. To be more precise, more or less during the first half of the 1990s (1991-1995) there was a peak of around 3.6 million of babies who today enter their thirties and begin to become parents themselves. Reviewing history. We explain ourselves. Paradoxical as it may be, in the 1950s and 1960s Korea had a very different problem than today: a very high fertility rate which led authorities to launch family planning programs. The objective: guarantee the country’s recovery after the war. The message that was launched was very simple: have fewer children (two, one) and guarantee them a better life. It worked so well that by the early 1980s the fertility rate had fallen below the replacement margin and Seoul decided change course. By doing so, it favored the rebound that would now be heating up the birth rate. According to that theory, what we see today is actually a … Read more

We have been dreaming of stopping aging for centuries. The question is if we are finally achieving it: Crossover 1×37

by

Myths such as that of the fountain of eternal youth have helped human beings through the ages. let’s dream of not aging and living forever. Reality is still cruel: Although life expectancy has increased, we age without seeming to slow it down. But there are those who argue that there may be. In this episode we have spoken with Dr. José Hernández, longevity expert and founder of a clinic specialized in Age Reversal, to understand what aging really is, why it is considered a disease today, and what technologies could allow us to go back biologically. In this debate we talk about information theory and epigenetic damage, cellular reprogramming, or how there are already large companies —and some billionaires— investing significantly in this. In fact, the most advanced science is accompanied by methods that seem much more effective not so much in slowing down aging but in ensuring that our physical condition is much better when this process affects us: Physical exercise is an absolute pillar of longevityassures this expert. Of course there are other factors that influence – diet and genetics, of course, do – but we are dealing with a question that has opened numerous avenues of research, some of which are promising. Who knows what can happen. On YouTube | Crossover In Xataka | Don’t tell me your age, tell me your grip strength: how simple gestures tell us how well we are aging

The world had been in love with US technology for 25 years. We are finally unhooking

by

We have been living within a digital ecosystem designed in the United States for more than two decades. Big technology companies not only built the dominant social networks, but also built a network of services around them without real substitutes. From Europe we have been talking for years about technological sovereignty and a possible disengagement – even if it is partial. There are more and more proposals, but at the moment it is more of a wish than reality. Difficult, but not impossible. Become completely independent from American technology In software it is complicated, but feasible. Our colleague Jose told it just a few days ago, leaving aside giants like Google, WhatsAppAmazon, or Instagram. The changes made something very clear: the United States has taken over the great pillars of daily technological life: Internet searches Sending messages online shopping Social networks Email accounts Operating systems The dependence is total, and assuming it is uncomfortable. Countries like France have banned to its officials the use of American platforms such as Zoom and Teamsto promote a video conferencing platform developed in France and under the name Visio. The objective is clear: reduce dependence on foreign technology, minimize costs and achieve a communication standard under European legal control. The UpScrolled case. Behind him TikTok ownership changewhich went from being mainly in Chinese hands to being under the lap of large American companies, the use of social networks like Upscrolledan app founded by the Palestinian Issam Hijazi as a challenge to big technology companies. During the last week of January, Upscrolled was the most downloaded social network above Threads, WhatsApp and TikTok in the United States App Store. A paradigmatic case in which Americans themselves opt for alternatives outside their country. The Proton case. Although less recent, the proton case It is one of the most ambitious in the last five years. From being protagonists only for ProtonMail (end-to-end encryption by default, European jurisdiction and independence from the Big Tech model), to a whole suite with calendar, VPN and storage alternatives. According to the company, its apps already have more than 100 million users. Good number, but far from more than 100 thousand millions of users who have Google services. The distance remains enormous, and explains why technological disengagement continues to be, for the moment, more of a political and cultural gesture than an everyday reality. Prepared for the worst. At the end of January, the Wall Street Journal reported a scenario starring even more tension. The Greenland case has been the flame necessary to finish lighting the fuseand the main managers of European strategic sectors want to move both their systems and data to local centers. Thinking about a 100% European software ecosystem does not seem entirely realistic. But imagining a scenario in which the dependency is not complete sounds a little better.
