The story of such an unusable approach that years passed by being the laughing of chemistry

by

Being a student, Susumu Kitagawa read a book that spoke of an old Chinese philosopher, Zhuangzi, who defended that we must question everything we believe useless. Even if you do not contribute an immediate benefit (or we cannot see it), that does not mean that it is not valuable. Kitagawa was able to devote himself to that idea in any field of human activity. But, as the book was from the Japanese physicist (and Nobel) Hideki Yudaka, he decided to devote himself to basic science. The most useless among the useless. What is the point of working on something like that? In 92, when he presented his first molecular construction, the truth is that his work honored that uselessness: “A two -dimensional material with cavities where acetone molecules could be hidden.” The curious thing, however, is that “he used copper ions united together by larger molecules” such as pieces of a puzzle. The curious thing for us now, of course. In the first half of the 90s, no one made the slightest case. Kitagawa I wanted to continue working With this type of materials, but the answer (again and again) was always the same: No. in the following years, each and every one of the aid he asked for were denied. He, of course, did not give up. Not even when in 97 he created a stable material (capable of absorbing and releasing methane, nitrogen and oxygen without changing shape) luck smiled at him: nobody saw his appeal. Not that they were wrong, but there were already better things. What sense did it have to continue working on something like that? The desire not to need ‘luck’ The answer to that I had Omar Yaghi. In that same year 1992, Yaghi achieved his great research project under the premise that “the traditional way to build new molecules was too unpredictable.” Until that time, chemicals were dedicated to putting things in a bowl, heat them and see what happened. Yaghi aspired to find more controlled ways of creating materials. Jordano’s team began to obtain good results when he began combining metal ions with organic molecules. They had found, so to speak, their Lego pieces: the elements that kept together and stable the most diverse molecules. Are you familiar? It was just the same approach that, independently, had launched Kitagawa. And yes, indeed, nobody thought it was something very useful. At least, it did not generate very useful things. Back to the origins Then, both Kitagawa and Yaghi were traced background for this new way of chemistry. There they met A speculative article Published in 89 by the journal of the American Chemical Society. The author, Richard Robson, worked in Australia and had been spinning all this since 1974. In those years, Robson He was in charge of converting wood balls into “atomic models” with which students could create molecular structures and familiarize themselves with the world of chemistry. To do this, he asked the university workshop to pierce holes in the balls. In this way, thanks to wooden rods (chemical bonds) atoms could be built. Immediately, Robson realized that the holes could not be placed at random. Each atom, forms chemical links in a specific way and, if I wanted to do the realistic model, needed to mark where the holes should be drilled. That is what gave him the track: in the position of the links there was an incredible amount of information. Moreover, those links hid the key to building new molecular structures easily and easily. Three ways to reach the same way of building the world Johan Jarnestad/Royal Swedish Academy of Sciences Metalorganic structures (which are called this type of structures) They serve almost everything: Capture carbon dioxide, separate water PFAS, administer drugs to the body or manage extremely toxic gases. Some may catch the ethylene gas from the fruit (to mature more slowly); Others may encapsulate enzymes that break down the remains of antibiotics in the environment. That is, we talk about one of the most versatile technologies of today and, for years, they were something completely useless. What he said before: pure basic science. An uselessness so enormous that the world can change.

Ukraine is basically a country made dron. So the war between humans has passed to an unpublished zone: underground

by

Of all the realities that war in Ukraine is showing us, there is one that has no discussion: drones are The Trojan horse on which they are going to sustain war conflicts From now on. In Eastern Europe we are Seeing scenarios that until recently they were more typical of Fantastic literature than reality. The prominence is such that the battle between soldiers is no longer getting rid of the ground. It is getting rid underground. The war in the bowels. Yes, Kharkiv’s front is being the scene of an unexpected phenomenon: Russian soldiers tried infiltrate pipes of gas and water, crawling through ducts Underground to overcome the Oskil River and establish positions closer to Kupiansk. It’s about The third time in which this tactic appears since the beginning of the invasion, and is a new defensive challenge for Ukrainian forces, which have reacted flooding, damaging and fortifying several of these passages, aware that the pipes form an extensive and difficult network to control. kyiv’s General Staff officially confirmed that the pipes had been used, although it stressed that the city remains under Ukrainian control and that most accesses have already been closely neutralized or monitored. Pipes such as espionage routes. Kupiank’s case is not isolated. As We count thenlast March, Russian special forces toured almost fifteen kilometers through a gas pipeline in Sudzha to throw a blow against the Ukrainian rear in Kursk, an episode that Moscow celebrated As tactical successalthough it ended with the annihilation of much of the infiltrated team. In Avdiivka, at the beginning of 2024, Russian troops They drained a pipe Water service and adapted it as a underground route, opening exits every hundred meters to facilitate the advance. These maneuvers, which evoke command operations of other warsThey take advantage of the industrial and energy fabric of Ukraine, a country crossed by large gas pipelines that for decades were key to the European supply of Russian gas and that today, to a large extent, are underutilized. The Ukrainian response. Before this Unusual threatUkraine has deployed measures from Creative Military Engineering. In Kupiansk, teams of the 429th regiment of unmanned systems used explosives to damage the point where a pipe crossed with the Oskil, causing its flood. In addition, wire wire have been introduced inside some ducts, with Videos that show Booby-Traped passages designed to catch or dissuade intruders. Although the controls They recognize that Russia could try to repair or reuse these passages, ensure that surveillance is constant and that each attempt will be answered. This deployment reflects how Ukrainian defense is not only fought on the surface, with drones, armored or artillery, but also a subsoil turned into a new front. The expansion underground. Plus: The war in Ukraine had already shown An underground face in the catacombs of Mariupol or in the trenches of Bajmut, but the use of gas pipelines and pipes A different dimension: abandoned industrial corridors that now become improvised military tunnels in fear that drones do not allow surface advances. With a diameter of more than one meter in some cases, they allow the passage of equipped men and even basic supplies. Its extension, designed to transport up to 140,000 million cubic meters of gas per year, constitutes a potential battlefield which multiplies the possibilities of infiltration and forces Ukraine to allocate resources to unexpected land. The paradox is evident: the same infrastructure that once connected Europe with Russian energy today are Combat scenarios where the immediate security of cities and defensive positions is played. Strategic implications. He Use of pipes as penetration routes Confirm two things. On the one hand, that drones have transformed What we understood as a contest so far. On the other, the Russian ability to exploit any loophole in Ukrainian geography, even undergroundtogether with the need for kyiv to develop multilayer defenses that cover from the sky, saturated with drones, to subsoils, now traveled by soldiers crawling into the dark. Beyond the punctual efficacy, These tactics They highlight the plasticity of contemporary war, where each civil infrastructure can be militarized and where combat is fought in secondary dimensions. For military analysts, the battle of pipes in Ukraine anticipates a future in which the defense of a country will depend both on the surface that its population inhabits, plagued with swarms, as well as on the bowels that run through its industrial networks, now turned into unexpected war tunnels.

Chema Alonso already has a new job after leaving Telefónica. He has passed to football

by

Chema Alonso has a new destination after his departure from Telefónica. The well -known hacker joins the Technical Referees Committee as an advisor to technological innovation and artificial intelligenceas announced by President Francisco Javier Soto on Monday and collects Ace. Why is it important. The arrival of Alonso to Spanish arbitration marks a radical turn in his career. After more than a decade in Telefónica trying digitally to Teleco, it will now apply its technological experience to a historically conservative sector that is in transformation: arbitration. The context. Soto seeks to completely modernize Spanish arbitration after years of controversies. Its strategy is to incorporate technological talent to improve arbitration decision making through AI. “We are going to start from scratch,” said the new president of the CTA. Alonso definitively abandons the world of telecommunications after his gradual abandonment, crystallized in The dismantling of your team a few days ago. His passage through the operator was marked by ambitious projects such as “Fourth platform“, the aura assistant or Movistar Homewhich did not reach expected commercial expectations. Organization chart of CTA for season 25/26. Image: RFEF. Between bambalins. The signing reflects the new Spanish arbitration strategy: betting on external technical profiles to solve structural problems. Alonso joins a renewed dome that includes Fernández Borbalán as technical director and Prieto Iglesias as head of the VAR, both old acquaintances of Spanish arbitration. The incorporation of Alonso raises some questions about his ability to apply AI to arbitration in a practical way. In Telefónica he gave grandiloque ads that rarely transformed into successful products, although some like Open Gateway They are good advances. Deepen. Spanish football will be its new fire test to demonstrate that it can transform traditional sectors with technology.

We have studied the bones of some mice that passed 37 days in space. The results are not optimistic

by

In November of this year, if there are no unforeseen events, in November of this year humanity will celebrate an anniversary. They will be fulfilled 25 years of human presence continued in space. The exploration of the last border has advanced significantly and humans spend more time in space and aspire to get further. But that has a price. The cost of microgravity. A team of researchers has analyzed The effects of a spatial mission on mice and the results do not invite optimism. They observed that the stay severely affected the bones of these rodents, who lost bone density in parts of their body. The femur, great victim. This loss of bone mass was not given in all areas equally. The team observed, for example, that the femur was one of the bones where the most extended bone cavities. In contrast, the lumbar zone of mammalian spine were the least affected. This makes the study responsible for the study suspect that the main trigger for this loss of bone density is in the microgravity. For example, the team indicates an alternative hypothesis, radiation. As they explain, the mice in the ISS were not exposed to large doses of radiation from space, but if this had been the loss of bone mass would have occurred from outside, that is, that the bones closest to the surface would have been more damaged, while the most surrounded by muscle bones would have been more protected. 37 days in orbit. The experiment used mice to explore how long rooms in space affect. They were used Two groups of micesome that were sent to the space station for a mission of 37 days and others that remained on Earth as a control group. The team responsible for the study simulated flight conditions in the control group to be able to make the conditions similar in everything except in the space stay. Similar, not identical. Those responsible for the study explain in a video how mice and humans keep important biological similarities that imply the changes we see in some are probably also giving in others. There are also differences to consider. For example, the fact that humans are bipeds implies that the bones of our lumbar zone have a more important role in supporting the weight of the upper part of our body. This implies that these bones are probably more affected in humans than in mice. The details of the study were published In an article In the magazine Plos One. If you don’t use it, you lose it. The body often tries to optimize resources. That is why a possible explanation to this phenomenon is there, in the idea that, since the bones in microgravity do not need to endure the weight of our body, they lose mass and density. Other risks. The study points to microgravity as the main suspect of the loss of bone density but this is not the only risk to take into account when we devise long -term space trips. Radiation is perhaps the most important in this sense, to the point that it was considered as a candidate to cause bone mass loss in mice. Radiation implies an additional problem and that, although in places like the moon and Mars the seriousness of the bodies could reduce the deterioration of the bones associated with the microgravity conditions, the same cannot be said of radiation. Moreover, the radiation in these environments is greater since the International Space Station even protected by the Earth’s magnetic shield.

This app was passed through a file administrator, but it was a North Korean spyware

by

Download applications from the official store of our Android device is the safest option. However, that does not mean that it is free of risks. Despite Google’s efforts to improve the security of Play Store, every so often some threat is filtered. This time it has been a North Korean spyware, which has managed to sneak out without raising suspicions. A spyware disguised as file administrator. Cybercriminals have perfected their tactics for camouflating malware within applications that seem completely harmless. Many of them even work normally, but in the background they execute malicious actions. File Manager, as his name suggests, was presented as a Android file manager, but actually hid something very different. According to the cybersecurity firm Lookout, File Manager hid a malware known as Kospy, which they believe with “high confidence” that was linked to North Korea. They have reached this conclusion, among other things, discovering that the malicious application uses domain names and IP addresses that were previously identified as present command and control infrastructures used by the groups of North Korean Cadincommers APT37 and APT43. What could the malicious app? Experts warn that this application collected a Alarming quantity of confidential information, including SMS text messages, call records, device location, stored files and even user key pulsations. In addition, I could access details of the Wi-Fi network, obtain a list of installed applications and perform even more intrusive actions, such as recording audio, taking photos with the camera and capturing screenshots in the background. A threat that was quickly neutralized. Although the Kospy spyware managed to infiltrate the Play Store, Google acted quickly. A company spokesman confirmed to TechCrunch that all identified applications were eliminated. According to a lookout screenshot, the malicious app came to download a dozen times before being removed from the Android store. Integrated protection measures. Android devices have several layers of safety, including Google Play Protect, which analyzes applications before discharge, inspects the device in search of malicious software and, if it detects a threat, can automatically deactivate the harmful application. In addition, some manufacturers incorporate their own safety solutions, adding an extra layer of protection for users. Avoiding the hook. The best defense against malicious apps is caution. Before installing any application, you should check what permits request. If a simple flashlight app requests access to our files, contacts or accessibility settings, something does not block. Another effective strategy is to download applications from official sources. Instead of looking for “Microsoft Authenticator” in the Play Store and risk falling into a malicious imitation, it is safer get the link directly from the official Microsoft website. The same applies to any other service: if we need the BBVA app, Better go to your website and find the corresponding link therethus avoiding falling into traps.

March is already the rainiest month since we have records in several areas of Spain. And only 10 days have passed

by

The other day I spoke with known that I told me that, when I was little, in the Ayamonte of the 60s and 70s, they went to school with water boots. Not only that, he told me, “I remember the white houses putting green because it kept raining.” At that time, I was not sure if it was true or it was nostalgia altering the memories of childhood, but seeing what is happening at the southern end of the peninsula, I would not surprise me anything. And it is that March 2025, just It has just converted in the most rainy month in several places in the country. Among them, the Aaemet Huelva Observatory – Ronda whose maximum historical data, since 1985, had been 164.6 mm. Yesterday, at 20:30, I had already collected 169.2mm. And there are 20 days left. Huelva, however, is simply a metaphor of Spain. An poisoned gift. Although the type of rain that is reaching us from the Atlantic is fantastic and does not have the torrentiality levels of the Danas, there are a point also begin to give problems. First because we have no infrastructure that can collect, accumulate and distribute all that liquid. As we commented a few days agothe red basin, the Odiel and the stones was above 94% of its capacity. That placed it at the level of the interior basins of the Basque Country and above Galicia or the Eastern Cantabrian. It is true that these data have trap (not only have little storage capacity, but in the area many coexit dead reservoirs Cargaditos of mining waste), but is indicative of what is happening in the rest of the country. Floods throughout the country. The clearest case has happened in the Toledo municipality of Escalona and its region. There, the Alberche River (just the one who, As we said yesterdayhe was going to receive an unprecedented amount of water) has overflowed and has caught many people with the step changed. However, more than 15 tajo stations They were yesterday Above the red warning threshold. And, if we expand the frame, we will see Floods in Sevillein The Golden Costain Vitoria or in Cartagena. Catalonia, for the first time in years, seems to drought endemic that lives. Are they good news? Yes, but with nuances. Obviously, water will come very well to face the next summer months. It gives us an irreplaceable margin to decide whether we want to learn from our previous mistakes. As explained in Datadista“From the deep drought of the 1990s, each dry period has served to implement emergency measures (…) or allow practices that were not eliminated when the rains returned, they were used to expand irrigation, increasing the problem of overexploitation and contamination of aquifers and wetlands to which they feed.” What are the nuances? The first is that ‘too much blow water’ also creates problems. Citrus flowers or Strawberry crops can begin to rot (or infect with fungi) in full campaign. That is, climate changes catch crops in different phases of the usual ones and that has impacts on the productive system. But the second nuance is perhaps more important: that the incentives not to take advantage of this blow of luck and not Implement the changes that The Spanish Water System needs. And, in the meantime, it does not stop raining. Nor does it seem to stop doing it.

I have passed from the iPhone 16 Pro to Samsung Galaxy S25 Ultra. I don’t echo (almost) anything of less

by

How well the Android high range works. It is something that I have been thinking for a couple of years but, especially, since the end of 2024. The last phone I have been able to analyze has been the Samsung Galaxy S25 Ultraa clear aspiring best android mobile 2025. A mobile that, although not the best in practically anything (except for integration of AI), makes check in everything. And this is usually more important than shining for some specific aspects. Battery, performance, cameras, software. Everything works as it should work. Something that seems basic on a mobile of more than 1,000 euros, but not everyone fulfills. Having analyzed phones such as OPPO FIND X8 PRO or the Magic7 Pro Honorthe feeling is different from the one I had a few years ago. The iPhone is no longer clear, saving an appearance. Let’s talk about power. It is me, the heavy power. I am obsessed with her, and I have my reasons. I dedicate myself to deepen telephones and, as a collateral effect, to be the official recommender of all my friends and acquaintances. There is something that ever has never been an exception: every time I have recommended a little powerful mobile, in less than three years everything has been complaints and regrets. To the question “Why do I want such a powerful mobile if you only use WhatsApp, Mail and some apps”, the answer is “so that in three or four years WhatsApp, the mail and those apps continue to work well.” There will be exceptions, of course, but in general terms mobile phones Poquipotent They are not made to last. A while ago, Apple’s superiority in processors was brutal. It was simply impossible to reach them in Benchmarks, and this helped an iPhone of a few years ago be more powerful than the Android of New Horn that were coming out. That ended a few years ago, and with the Snapdragon 8 Elite and MEDATEK DIMENSITY 9400the competition is more equated than ever. Everyone has an absurd power today, and more than necessary in a few years. In the case of Samsung, it has the Qualcomm and, although it is not the mobile in which it is best optimized, it is simply impossible to say that it works worse (or better) than the iPhone. Simply, they fly. The software, that great barrier. One UI 7, as I counted in my impressions with the systemit is for me the best software that exists in Android. At least, in this Ultra S25 (a separate case is how it works in less powerful models). Six years of updates, the new live activities of iOS inheritance, and a really useful artificial intelligence burden. Historically I have been very Pixel Experience, but Samsung’s Rom provides added value that no other gets. I am a Mac user, Airpods and iPad, I don’t hide. The integration between Android and these devices remains simply terrible, without half inks. Nor (even if you try and say yes) there are real alternatives to Airdrop, nor are new system versions as fast as in iOS. The quality of some apps is lower and, if you care a lot about the quality of the contents when uploading them to social networks, this is not your operating system. Saving this, iOS and Android have been approaching over the years. I still defend that, objectively, iOS is more stable and is better refined than Android. Despite this, the evolution of the Google operating system in recent years, especially if we talk about what manufacturers have done with their personalized roms, has been spectacular. Let’s stop fighting for the camera. One of these two photos is taken with the Samsung Galaxy S25 Ultra. The other is taken with the iPhone 16 Pro. One is clearly better than the other, but I am not going to tell you which, I will let you decide in comments. The key here is that, although I am clear that there is a phone that makes better photos than the other, the differences between high -end devices have been minimized over the years. Every year, in the great photographic comparison that I prepare in Xataka, I have to spend hours expanding the photographs and analyzing elements such as the reflexes that are generated in the lenses or other points to be able to determine a winner. Without expanding and without fixing in detail I am clear: practically no average user could objectively differentiate which photo is better than another. It would simply be in a position to choose which one likes the most. And this is excellent news. Buying a high Android range is no longer a bad idea. There was a time when buying a high -end mobile was to spend more than 1,000 euros on a phone that would be updated for two years and with a power about two years behind the iPhone. This is why, historically, it has been very difficult for me to recommend the purchase of Android mobiles in this price range. With the advances in hardware, things have changed a lot in recent years. To the point that what I look most is in the ROM and the user experience that the buyer will have, more than in the rest of details and differences between devices. And here, next to Google, Samsung is the one who is moving the baton. Image | Xataka In Xataka Android | After a decade with an Android mobile, three months ago I went to iPhone.

How wealth and land passed from mothers to daughters (and not to men) in Britain 2,000 years ago

by

Image source, BOURNEMOUTH UNIVERSITY photo caption, The investigation found several skeletons of women buried with valuable objects such as pots. Item information Author, Georgina Rannard Author’s title, Science reporter, BBC 1 hour 2,000 years ago women in Britain passed land and wealth to their daughters, not their sons, as communities were built around the female bloodline, according to new research. Skeletons unearthed in Dorset contain DNA evidence that Celtic men moved to live with their wives’ families and communities. Scientists found evidence of an entire community built around a family’s female bloodline over generations, probably originating from a woman. “This points to an Iron Age society in Britain in which women had a lot of influence and could shape its trajectory in many ways,” explains Dr. Lara Cassidy of Trinity College Dublin, Ireland, lead author of the investigation. Image source, BOURNEMOUTH UNIVERSITY photo caption, Archaeologists found well-preserved skeletons in the clay soil of Dorset. It is the first time in the history of ancient Europe that this evidence has been documented. of communities built around women. Scientists believe that the communities also invested heavily in their daughters, as they would likely inherit their mother’s status. “It’s relatively rare in modern societies, but it might not always have been that way,” Cassidy says. The team found evidence that this occurred in numerous places in Britain, suggesting that the practice was widespread. The communities analyzed lived around the same time as Boudica, the warrior queen who led a rebellion against Roman invaders in eastern England around AD 61. Dr. Cassidy sequenced DNA taken from the bones of 57 individuals from a tribe called Durotriges. People lived in Winterborne Kingston, Dorset, around 100 BC to 100 AD The skeletons were unearthed from a cemetery by a team of archaeologists from Bournemouth University, England. By tracking mitochondrial DNA, which is only passed between women, Cassidy discovered that most of the women in the community were related by blood ties that went back to previous generations. Instead, there was a lot of diversity in the Y chromosomes, which are passed from father to son, indicating that men from many different families married into the community. Image source, BOURNEMOUTH UNIVERSITY photo caption, The skeletons of people from the Durotriges tribe were very well preserved. DNA analysis also indicates that most of the ancestral line can be traced back to a single woman. The work shows that this society was what is known as matrilocal, meaning that a married man moved to live in his wife’s community. “The most obvious benefit for a woman is that if you don’t leave home, you don’t abandon your support network. Your parents, siblings, family members are still around you,” says Dr. Cassidy. “It is your husband who arrives, he is the stranger in the community and depends on your family for his livelihood and his land,” she adds. The researchers they found the same evidence of matrilocality in bones from other cemeteries, including those in Cornwall and Yorkshire. The researcher says evidence of powerful women in ancient communities has often been dismissed as isolated, not the norm, but these findings challenge that way of thinking. Archaeologists Miles Russell and Martin Smith found other evidence that women had high status. Image source, BOURNEMOUTH UNIVERSITY photo caption, The team from Trinity College and Bournemouth University excavated and analyzed skeletons of 57 people “We found tombs decorated with great care and with objects of great value. In each of the cases they were tombs of women, so we believe that wealth was transferred through the female line,” says Professor Martin Smith of Bournemouth University. The findings also support Roman writings of the time which suggested that women in Britain were quite powerful, more so than in Rome. But the Romans, like Julius Caesar, saw it as a sign of backwardness. “Women in Britain had power and it was a more egalitarian place. That was the biggest problem the Romans had with the British because Rome was a deeply patriarchal society. For them, it marked the British as the quintessential barbarians,” she says. Professor Miles Russell of Bournemouth University. Most societies today are patrilocal, meaning that women move to their husbands’ communities. But there are some matrilocal communities today or in the recent past, such as the Akan in Ghana, West Africa, and the Cherokee in North America. Scientists say Iron Age Britain may have been matrilocal because men were frequently outside fighting. Dr. Cassidy compares it to World War II, when women gained more political and economic power. Matrilocal societies are also less likely to experience internal conflict, he says. “They can promote feelings of unity between communities and neighboring towns. They disperse groups of related men, preventing them from developing strong loyalties and starting disputes with related men who live nearby,” suggests the researcher. The findings were published in the scientific journal Nature. Subscribe here to our new newsletter to receive a selection of our best content of the week every Friday.
