That Iran shot down a US F-15 was something unusual. The problem is that they have opened the missile… and everything points to China

by

In 1960, when an American U-2 spy plane was shot down over the Soviet UnionWashington initially believed it was facing a military problem. He ended up discovering that the incident had diplomatic consequences much larger and blew up a summit between the two superpowers. Because sometimes a single downed plane reveals a story much bigger than the battle in which it fell. The takedown that changed the conversation. He downing of an F-15E on Iran last month was, in itself, an extraordinary event. It had been decades since a United States fighter had been shot down by enemy fire, and the rescue movie operation later, with one of the crew hiding for two days in the Zagros Mountains, underlined the seriousness of the episode. However, as investigations continue, the incident is shifting from being a story about Iranian military capabilities to something else: a story about China. According to cited sources by NBC News the suspicion that the plane was hit by a portable anti-aircraft missile (MANPADS) of Chinese manufacture has shifted the focus from the battlefield to a much more uncomfortable question for Washington: to what extent Beijing is helping to sustain Tehran’s military capacity. More important than the missile. From a military point of view, a portable anti-aircraft missile is not a revolutionary weapon. Its appeal lies precisely on the contrary: It is relatively cheap, easy to deploy, and capable of threatening even extremely sophisticated platforms if circumstances are favorable. Hence, what has aroused American interest is not so much the type of weapon used as its possible origin. If suspicions are correct, the shootdown would demonstrate that Chinese technology has ended up participatingdirectly or indirectly, in one of the more symbolic hits suffered by American aviation in years. From that perspective, the discussion then stops revolving around how Iran managed to shoot down an F-15 and begins to focus on what role played China to make it possible. The shadow of broader support. Because suspicions are not limited to the missile. US sources also suggest that China may have provided Iran with radar systems capable of detecting stealth aircraft and access to space capabilities that would facilitate the location of targets. So far none of these accusations have been conclusively proven publicly and Beijing categorically rejects them, but together they paint an image that is worrying in Washington: that of a technological support network which, without involving direct military involvement, could significantly increase Iran’s ability to challenge the United States and its allies. In this context, the downed F-15 becomes tangible proof of a broader phenomenon that US officials have been denouncing for some time. The contradiction of American diplomacy. The situation is especially delicate because the United States simultaneously needs to contain Iran and keep channels open with China. Beijing is the main buyer of the iranian oil and one of the few actors with enough influence to put economic pressure on Tehran. During negotiations to reach a ceasefire, the Trump administration sought precisely that collaboration. But every new accusation on Chinese missiles, radars or satellites used by Iran complicates that balance. Washington thus finds itself in an uncomfortable position: it needs China to contribute to stabilizing the region while accusing it of providing tools that strengthen one of its main adversaries in the Middle East. The real message. That’s why the downing of the F-15 It has a relevance that goes far beyond the loss of a plane. What is at stake is not only the effectiveness of Iranian defenses, but the American perception that more and more regional conflicts are connected to global strategic competition. against China. The investigation on the missile seeks to determine how the fighter fell, but also who was behind the technology that made it possible. In a sense, Washington has opened up the missile to examine it piece by piece, and in doing so has discovered that the biggest questions no longer point solely to Tehran. They aim more and more towards Beijingwhere the United States believes is a growing part of the economic, technological and military infrastructure that allows its rivals to challenge its power in different corners of the world.

In Zambia, gas bubbles in hot springs point to an unusual birth: a new tectonic plate

by

In 2005, the floor of the Afar Desert in Ethiopia suddenly opens up along more than 50 kilometers in just a few days after an intense seismic and volcanic sequence. For many geologists, that image was like observing in real time the type of fracture that, in millions of years, could end. creating a new ocean. Zambia has just given the most serious warning. Bubbles as an almost unequivocal sign. In Zambia, simple bubbles emerging from hot springs have begun to reveal something much bigger than a local geothermal phenomenon. Scientists at the University of Oxford believe have found signs that the southern African subsoil could be entering an early phase continental fracturea geological process so slow that it is imperceptible for human life, but so gigantic that it can end up rdrawing entire maps. The key is in the helium detected in the thermal springs of the Kafue Rift: Its isotopic composition contains too much helium-3, a chemical marker directly associated with the Earth’s mantle. Translated into less technical language, it means that fluids from dozens of kilometers beneath the crust are finding ways to ascend to the surface. And that, for geologists, is an extremely serious sign that the African crust could be starting to break down from within. A silent crack beneath the continent. Rifts are not simple faults or isolated earthquakes. They are areas where the lithosphere begins to stretch and weaken until, in some cases, it ends separating into tectonic plates different. Most never make it that far and remain an unfinished geological scar, but the Kafue Rift presents something that changes the scene: a active connection between the mantle and the surface. The researchers analyzed gases from eight wells and hot springs, six within the suspected area and two outside it to compare results. Only within the rift did they appear associated chemical signatures to the deep interior of the Earth. In addition to helium, they also detected carbon dioxide with characteristics typical of mantle fluids. For scientists, this suggests that the fracture is no longer solely superficial and that the system could be entering into a tectonic phase more advanced than previously thought. Location map of the extensional zone within the Central African Plateau of Zambia. The Kafue Rift is connected to the Luano and Luangwa rifts to the northeast, and to the western branch of the EARS in the Rukwa rift (RRB) and the Rungwe Volcanic Province (RVP) The possible birth of a new plate. The hypothesis is especially relevant because the Kafue Rift is part of a huge strip of geological weakness about 2,500 kilometersone that crosses Africa from Tanzania to Namibia. For years, many researchers had considered that the great candidate to divide the continent was the East African Rift, in Kenya and Ethiopia, where volcanic and tectonic activity is much more visible. However, the new study of Oxford researchers suggests that the southwest African system could have important structural advantages. According to Mike Dalythe natural crustal weaknesses in that region are better aligned with the tectonic forces acting around Africa, which would reduce the resistance needed for future continental breakup. In other words, the Zambian bubbles could be signaling the extremely slow birth of a new African tectonic plate. The continent moves, even if you don’t notice it. The investigation It also serves as a reminder that Earth is still a planet geologically alive. Hundreds of millions of years ago, all continents were part of Pangea before slowly breaking up into their current shape. That process never stopped. Beneath our feet, tectonic plates continue to shift, recycling minerals, raising mountain ranges and opening new oceans. Africa is today one of the places where this dynamic can best be observed. From the Afar Depression to the East African Rift, the continent already presents huge tectonic scars visible from space. What is happening in Zambia could be an additional piece of that continental puzzle, although scientists insist that we are talking about time scales of millions of years and not immediate changes. A geological fracture… and economic opportunity. Beyond scientific fascination, the discovery It has very real economic implications. Early rift systems typically offer relatively clean access to geothermal energy and gases valuable substances such as helium and hydrogen, increasingly important for the technology and energy industry. Unlike mature volcanic zones, where fluids appear mixed with more aggressive and difficult to handle gases, in Kafue the material from the mantle still arrives relatively “pure”. In fact, that is precisely the reason why several energy companies already They are funding research in the region. The problem is that the authors of the study themselves they ask for caution: The samples come from only a specific part of the system and it remains to be seen whether these signals are repeated throughout the entire fracture. But even with caution, the idea is so powerful that it is already on the table: in Zambia, the bubbles that silently emerge from a hot spring could be announcing the beginning of a continental separation that will one day change Africa forever.

The complex of the wide face and the unusual solution that obsesses South Korea: elf ears

by

Jung Da-yun was not satisfied with what the mirror returned to her. At 31 years old, this influencer South Korean woman felt she had an unusual defect: her ears were not big enough. According to a report from Wall Street JournalJung went to a clinic in Seoul, paid the equivalent of about $70 and underwent hyaluronic acid injections into his cartilage. The result was immediate: his ears leaned forward, rising above his face. Suddenly, his face looked slimmer, younger, and proportionate. “I was very happy with the results,” she confessed. This scene, which in the West could seem like the script of a satire, is a latent reality in East Asia. While in the United States or Europe, people with prominent ears go to the surgeon to hide them or glue them to their heads — a practice that in Korea is “creepy” in the eyes of some, as explained by the influencer Korean-American Krystal Lee—in Asia, the projection of the ears has become the Holy Grail of aesthetics. The magazine MEGA has baptized him such as “silent retouching”. “When I was in China, one of the dermatologists told me that this is one of the procedures he performs the most, and I couldn’t believe it,” dermatologist Jenny Liu tells the same medium. And the true art of this intervention lies in sculpting the face, hiding the trick in plain sight: behind the ear. Although they have coined it with the name “elf ears”, the goal is not to emulate the sharp and fantastic point of the elves of The Lord of the Rings. The clinical and informal term is closer to the concept of “fairy ear” (fairy ear), a procedure that seeks to alter the natural position of the pinna. According to Dr. Jung Gyu-sik in the studio Plastic & Reconstructive Surgery – Global Openthe technique consists of injecting between 1 and 2 milliliters of hyaluronic acid filler in the most lateral part of the helix and in the auriculocephalic sulcus. The goal is to increase the angle between the skull and the ear. It is fast, non-invasive, almost painless and its effects last between 6 and 12 months. Dr. Jung himself confesses in it Wall Street Journal having performed up to 20 of these injections in a single day. Where did this fever come from? The trend germinated in China about five years ago, where the hashtag “Aesthetic elf ear surgery” today exceeds 780 million views on the social network Weibo. However, the definitive outbreak occurred in South Korea when Mimi, a well-known singer of the K-pop group oh my girlconfessed to using special adhesive tape to simulate this effect. Overnight, searches for “ear filler” exploded 1,200% on BarbieTalka popular South Korean aesthetics platform. Those who don’t want needles turn to these adhesive tapes that cost just $3. The terror of “pancake face” To understand this fashion you have to look away from the ear and focus on the cheek. South Korean researcher and academic Leem So-yeon sums it up perfectly in Wall Street Journal: “It would be reductionist to frame it simply as an obsession with ears. Ultimately, it’s a procedure to make the face appear smaller. The ears are just the middle.” This is an optical illusion trick based on negative space. Dermatologist Danny Guo details in the magazine MEGA Asian patients often have naturally prominent cheekbones (zygomas). Since they do not want to increase the volume of their cheeks, injecting behind the ear creates a “lateral structure” that visually slims the contour of the face. All this is born from a deep cultural complex. In East Asia, wide faces and large heads are heavily penalized. While in China they make fun of what they call “tortia faces”, in South Korea a sharp “V” shaped jaw is idolized, details the WSJ. But it is not a mere narcissistic whim; It is a tool for work and social survival. As John P. DiMoia explainsa professor at Seoul National University, young people do not operate out of ego: “It’s about looking my best for my job interviews.” This pressure It is better understood under logic that, in South Korea, “presenting the best version of oneself is a sign of respect for others.” The “Bai Fu Mei” canon Science supports that although there are universal beauty traits such as facial symmetry, the perception of attractiveness varies dramatically by ethnicity. A study of the medical journal Clinics in Dermatology points out that traditional Asian beauty prefers wider faces but with lower vertical height, an inverted triangle shape and a reduced projection of eyebrows and chins. Hence the obsession with fine-tuning the structure at any cost. But the sociological background is even darker. As we detail in XatakaSouth Korea’s strict standards are a form of “cultural racism.” It is a system that excludes different bodies and skin tones under the protection of neo-Confucian traditions, where whiteness and delicacy symbolized social status (the Chinese concept bai fu mei: white, rich, beautiful). By going global through K-pop and K-dramas, the Korean aesthetic or K-Beauty industry has attempted to impose an exclusive standard on the rest of the world. In fact, Korean brands They had to apologize publicly or drastically expand their makeup palettes (such as the TIRTIR brand, which increased sales by 55,000% by offering 40 shades after complaints from black content creators) because, simply, the most innovative industry in the world did not make products for dark-skinned people. “Elf ears” are not born in a vacuum. They are the symptom of a hypertrophied body modification industry. Seoul hosts the “Belt of Beauty”a neighborhood smaller than Central Park but with more clinics than Los Angeles, Miami and Rio de Janeiro combined. As much of the Korean population has already widened their eyes, raised the bridge of their noses and sharpened their jaws, the industry desperately needs to invent new areas of growth. And foreigners are answering the call. According to data from the Ministry of Health cited by the specialized platform Seoulzin … Read more

Netflix premieres today one of the best dystopian series of all time and breaks a sadly unusual record

by

When ‘The Handmaid’s Tale‘ premiered on Hulu in April 2017, winning the Emmy for Best Drama when it was still a cult series. Now, a year after airing its sixth and final season, the series lands on Netflixbreaking a record that is as pleasant as it is sadly unusual: it is a series with a very specific production company (owned by Disney), but in Spain it can be accessed on practically all platforms. It’s on Netflix, yes, but also on Disney+ (where you can also see – this time, exclusively – its prequel ‘The Testaments’), Prime Video, HBO Max and Movistar Plus+. The weight of the series It is well understood by reviewing its impressive collection of awards: six seasons, 76 nominations and 15 Emmy wins, including the historic award for Best Drama in its first season, the first ever awarded to a streaming platform. streaming. That first season also won for writing, directing, leading actress (Elisabeth Moss), supporting actress (Ann Dowd) and guest actress (Alexis Bledel). For its last season it only received one nomination, but by then it had already made history. In its terrifying dystopian vision, ‘The Handmaid’s Tale tells us how in the near future, the United States government has been overthrown by a theocratic movement that founds the Republic of Gilead. In the face of a global birth crisis, the new regime enslaves the few remaining fertile women (the Handmaids) and assigns them to elite families to father children through ritualized rape. The series follows the awakening, escape and rebellion of one of these maids. Margaret Atwood, author of the original 1985 novel, stated that nothing in the novel was pure invention: everything had already happened. The repressive Taliban system, which since its return to power in 2021 has denied women access to work, education and almost any form of presence, has been repeatedly pointed out as the most direct parallel with the Republic of Gilead. But in the United States, debates about reproductive rights in different states have continued to fuel the political reading of the series. Nobody is spared. For this reason, the Handmaids’ clothing has become a symbol of feminist protest, thanks to a series that remains as shocking and terrifying today as when it premiered.

an unusual toll to revolutionize global maritime trade

by

In the 16th century, several sultans of the Ottoman Empire came to seriously study the possibility of open an artificial road next to the Bosphorus to better control maritime traffic between the Black Sea and the Mediterranean… the project was canceled again and again for centuries due to wars, lack of money and strategic doubts, but the idea never completely disappeared from Türkiye. The old Turkish obsession. While the Strait of Hormuz has become one of the largest sources of tension of the planet due to the war between Iran, the United States and Israel, an idea that has been around Turkey’s politics and strategy for years has once again gained prominence: building a gigantic artificial canal parallel to the Bosphorus to create a new sea route under Ankara’s direct control. It is not just about decongesting Istanbul’s naval traffic. Behind the project appears a much greater ambition: converting a free natural passage into an alternative corridor capable of generating incomegeopolitical influence and pressure capacity on part of international trade. Precisely now, when Hormuz demonstrates the extent to which a maritime bottleneck can disrupt the world economythat old Turkish idea it rings again with more strength. The Bosphorus and its importance. He Bosphorus It is much more than a strait that divides Istanbul between Europe and Asia. In reality it is the only sea exit towards the Mediterranean for countries such as Ukraine, Georgia, Bulgaria or part of southern Russia, and one of the busiest corridors in the world. Every year, thousands of oil tankers and freighters cross a narrow road, full of curves and surrounded by a gigantic city of millions of inhabitants. Türkiye has been defending for years that this trafficking represents an enormous risk both for maritime security and for Istanbul itself, especially after several accidents of ships occurring next to historic and residential areas. The problem for Ankara is that the Bosphorus is regulated by the Montreux Convention of 1936, which guarantees free transit and greatly limits the possibility of charging direct tolls to ships. The idea that could change the rules. There appears the real core of the project Istanbul Canal. As it is an artificial route and not a natural strait, Türkiye could try apply rates and services transit routes similar to those of Suez or Panama without formally breaking international maritime law. For years, this possibility seemed more like a geopolitical fantasy than a near reality, but the Hormuz crisis aims to restore prominence to an uncomfortable question: what happens when large maritime corridors stop being simple routes and become tools of economic and political pressure. Iran has already hinted at the possibility of demanding payments in Hormuz, something that has alarmed organisms international organizations and the great maritime powers. In this context, the old Turkish project begins to fit within a broader trend: transforming certain strategic steps into infrastructures capable of generate multi-million dollar income and increase the political weight of the countries that control them. Istanbul, Türkiye, divided by the Golden Horn and the Bosphorus Strait. Erdogan’s dream. Yes, because Recep Tayyip Erdogan turned the Istanbul Canal into one of its great symbols politicians. In fact, he has compared it to Suez and Panama, he has described it as a project aimed at transforming the Türkiye’s international role and has presented it as a work capable of turning Istanbul into one of the great logistics centers in the world. On paper, the channel would have 45 kilometers longwould allow the passage of large oil tankers and freighters and would be accompanied by ports, logistics zones, new urbanizations and enormous real estate developments. It would also physically split the European part of Istanbul, creating a kind of gigantic artificial island between the Bosphorus and the new canal. The big question: if anyone would pay to use it. The enormous problem of the project has always been the same. Although Türkiye could charge tolls on the new canal, the Bosphorus would still exist as a free alternative. That doubt has been haunting the plan for years: why a shipping company would agree to pay millions to cross an artificial route when it has another relatively nearby toll-free route. Ankara is confident that congestion, navigation risks and possible delays will push many companies to choose the new corridor, especially for dangerous goods and large tankers. But many economists and maritime experts believe that the real profitability of the project remains uncertain and it would depend on very specific international scenarios, precisely like those that the Hormuz crisis is causing today. Criticism within Türkiye. Furthermore, the Istanbul Canal It has never been solely a discussion about maritime trade. For years it has been accumulating criticism for its ecological impacturban and economic. Scientists and urban planners warn that the canal would cross forests, aquifers, agricultural areas and very sensitive ecosystems in the north of Istanbul. Not only that. There are also fears about how alter the currents between the Black Sea and the Sea of ​​Marmara, affect marine biodiversity or increase problems related to earthquakes and landslides in an already very seismically vulnerable region. Plus: the projected cost (which different estimates place between 15,000 and more than 60,000 million dollars) continues to generate doubts even among sectors that support strengthening Turkey’s strategic position. Hormuz has reactivated the dream. For years, the Istanbul Canal seemed to move between bombastic announcements, delays, political disputes and financial doubts. but the war around Hormuz has returned to put on the table a much broader issue: the enormous power that certain maritime points have to alter supply chains, energy markets and entire geopolitical balances. Türkiye now watches as the entire world discusses blockades, maritime insurance, tolls and control of strategic routes while your old project appears again, at least in some sectors of the country, as a possible tool to increase your global influence in a century where maritime corridors once again become central pieces of international power.

Ukraine is bringing its drones dangerously close to Moscow. And he is doing it with an unusual weapon: Grand Theft Auto V

by

In 2002, during a US military exercise known like Millennium Challengea retired general managed to surprise to a technologically superior fleet using unconventional tactics and unexpected means, and did so to the point of virtually “sinking” several ships in a matter of minutes. That simulation left an uncomfortable conclusion For many strategists: in certain scenarios, it is not always whoever has the most means who wins, but whoever best understands how to adapt to new forms of combat. From video games to the real battlefield. The story They told Insider. Apparently, Ukraine has found a totally unexpected way to accelerate the training of drone pilots and perfect its field of action: video gamesand in particular in the environment achieved by Rockstar in Grand Theft Auto Vwhere operators perfect reflexes, coordination and decision-making in simulated scenarios. This practice does not replace military training, rather it complements it, and reveals the extent to which modern warfare is absorbing skills born outside the traditional sphereincorporating a generation accustomed to controls, screens and virtual environments. What begins as a simulation ends up moving to real operations where there is no margin for error, consolidating a combat model in which the line between game and war turns increasingly diffuse. Drones are approaching Moscow. In parallel to this training with GTAV, the range of the Ukrainian drones has been growing steadily until reaching areas ever closer to the political heart of Russia. They remembered in Forbes that deep attacks inside Russian territory, some a few kilometers away of the Kremlin, are breaking the perception of invulnerability that protected Moscow for years. The campaign does not seek only to destroy objectives, but to demonstrate penetration capacity and generate constant pressure that forces us to redistribute defenses and assume that the conflict is no longer far away, but increasingly closer. Victory Day under a new shadow. Yes, because the proximity of May 9, one of the most symbolic events For the Kremlin, it adds a particularly delicate dimension to this development. The parade is not only a military display, but a key piece in Russia’s narrative of power and control, and any alteration, even indirect, would have a disproportionate impact. The fact that it is being contemplated reduce its scale or modify Its format reflects the extent to which the drone threat has changed the strategic calculus, turning a celebration designed to project force into a potential point of vulnerability. A defense saturated and tested. The truth is that although Moscow remains one of the most protected spaces of the world, the accumulation of attacks is straining your systems defensive. Multiple layers of air defense, designed to intercept threats, now face a constant stream of drones seeking to overwhelm them, identify gaps, and wear them down over time. This approach does not depend on a single decisive blow, but on prolonged pressure that forces Russia to defend more and more points at the same time, progressively eroding its response capacity. Putin, more isolated and more protected. In fact, this week they explained in the Financial Times that, in this context, security around Vladimir Putin has visibly tightened, reflecting growing concern about possible attacks, including those carried out with drones. How much? Apparently, the president has reduced their movements, spend more time in bunkers and operate under stricter security protocols, while their environment is subjected to increasingly rigorous controls. This evolution not only responds to physical risks, but also to the need to preserve an image of control at a time when the conflict begins to feel closer to the center of power. The psychological war that accompanies technological warfare. Beyond the material impact, the Ukrainian drone campaign is having a increasing psychological effectboth in the political elite and in Russian society. Each raid that breaks through defenses reinforces the idea that no place is completely safe, weakening a narrative built on distance and control. If you want too, while drones continue to advance and pilots train even in virtual worlds like GTAVthe war enters a phase where the perception of risk it’s so important as the real damage, and where the pressure on Moscow increases just when it most needs to project stability.

Germany has found a source of perovskite for solar panels in an unusual place: bullets from the 17th century

by

Solar energy is, with the permission of wind energy, the renewable energy that has stood out the most and best in the energy transition on a global scale. There are already solar parks everywhere: from fields that They fill the emptied Spain to deserts passing through the tibetan plateau and also in high seas either in lakes. And although the most common technology is crystalline silicon, perovskite is the great promise. There is a compelling reason to bet on perovskite: a record efficiency certified in a laboratory. up to 26%. However, a large-scale deployment of perovskite solar cells requires a large-scale, sustainable supply of high-purity lead iodide. We have come across lead: a toxic element whose mining is not exactly sustainable. On the not-so-good side, recycling it to the required purity levels is a technical challenge that a German research team at the Helmholtz Institute in Erlangen-Nuremberg has just solved. And in what way: have achieved converting 17th century musket balls into high-performance solar cells. The idea. It consists of a process of upcycling (upcycling) in two stages: first a non-aqueous electrochemical route and then purification through the crystallization of single crystals, quite different from traditional methods based on strong acids and large volumes of water. To demonstrate the robustness of their method, the team used lead bullets from the 16th and 17th centuries as raw material, a truly complicated material in that it contains carbon residues, metallic inclusions and oxidation patina. If the process can clean up this type of historical residue, it can handle virtually anything you throw at it (obviously any lead residue). Recycling bullets into solar cells transforms lead waste into a clean energy source. Why is it important. Perovskite solar cells require extraordinarily pure lead iodide, and achieving that level of purity from contaminated waste was until now a challenge without a practical solution that this research has solved: the team manufactured solar cells with their recycled material and obtained 21% efficiency, practically identical to the 22% of devices manufactured from industrial synthesis. Beyond the technical result, the process solves two problems at the same time: it offers a way to supply the enormous demand for lead iodide that will be generated by the take-off of perovskite solar cells without resorting to new mining and at the same time eliminates a toxic pollutant whose current management is expensive and environmentally problematic. Context. As we mentioned above, lead is an abundant waste: it comes from used car batteries, electronic scrap, construction materials or ammunition, among others. Lead recycling is dominated by car batteries, which have very high recovery rates in developed countries. The problem is in the rest: In 2018, only 48% of the world’s residual lead at the end of its useful life was recovered and in more dispersed flows such as electronics or construction, the recovery is even lower. Conventional recycling returns metallurgical-grade lead, useful for batteries and alloys, but far from what the solar industry requires. In addition, they are slow processes that generate toxic gases such as nitrogen oxides and large quantities of contaminated wastewater, up to 70 liters per kilogram of lead iodide produced. Traditional high-temperature purification methods are expensive and complex. More robust, adaptable and cleaner extraction and purification methods are needed for perovskite technology to truly scale. How they do it. The bullets are cleaned with dilute nitric acid, melted and molded into rods that act as electrodes in an electrochemical cell with acetonitrile and dissolved iodine. When current is applied, lead reacts directly with iodine and precipitates as lead iodide with 94% efficiency. Doing it this way, in a non-aqueous medium, is a deliberate decision to avoid introducing impurities that would accelerate the degradation of the perovskite. The resulting lead iodide still contains metallic impurities, so it is not suitable for solar cells. That is why it is subjected to a second purification stage through crystallization at a controlled temperature for about 70 hours. The process is exceptionally selective: as the crystal grows, it expels contaminating metals such as silver or copper, raising the purity of the material to levels comparable to or even higher than the highest quality commercial standard. Yes, but. The process works and the results are solid, but scale matters: at the laboratory level, productivity is just 0.05 grams per hour and each purification cycle lasts about 70 hours. The leap to an industrial scale requires solving the recovery of organic solvents, controlling the passivation of the electrodes and substantially improving the productivity of the process. The research team does not hide it: the chemistry is proven, but the distance from the laboratory to a real production plant is long and will determine whether we end up seeing perovskite panels made with recycled lead or if this remains like a shiny piece of paper in a drawer.

NASA captures the unusual trail of the “twin” tornadoes in Mississippi from space

by

If we look at the Mississippi from 700 kilometers above sea level, the landscape we usually see is a green carpet of forests and agricultural fields. However, last March this carpet was ‘torn’, as NASA could see through the Landsat 8 satellite. The images obtained revealed something extremely strange: “scars”, which are nothing more than traces of total destruction that reveal the trajectory of one of the most violent tornado outbreaks in the last decade. The surprising thing. It is not the magnitude of the damage that the passage of these could have generated. tornadoes down the Mississippi, but the geometry it has. And in Walthall County, satellites have immortalized an extremely rare phenomenon: two perfectly parallel scars. Something that represents a “mute” testimony of two tornadoes that advanced hand in hand, wreaking chaos. Paths of destruction. The tornado outbreak in question occurred between March 14 and 16, 2025, and the truth is that it will be remembered for how aggressive it was. Specifically, data from NASA’s Earth Observatory and the National Weather Service (NWS) suggest that they were developed a total of 113 tornadoes in just three days, which affected 14 states. But it was precisely in Mississippi where the atmosphere decided to leave a unique visual signature. Landsat images show these two almost parallel tracks, like train tracks, near Tylertown. Your description. The first of these traces indicates that it arose due to the tornado EF4which had a journey of 90 km with estimated winds of 274 km/h. The second trace, which is shorter, but just as destructive, has a distance of 15 km, and was generated by a different tornado that followed an almost identical path. This phenomenon of “twin tornadoes” leaving parallel trails is a statistical rarity that allows meteorologists to study how supercells interact with each other under conditions of extreme instability. An ‘X’ of disaster. Not only were these parallel trails recorded in Mississippi, but in Covington County researchers they found also another quite unusual pattern: two scars that intersect almost at right angles forming a large ‘X’ over a wooded area. As if a great pirate treasure could be found underneath. And it was not a sensor error, since according to the data, two different tornadoes crossed their paths in an interval of just 40 minutes. For families in the area, it was a statistical nightmare: being hit by a natural disaster and, before an hour had passed, watching another large funnel pass through the rubble of what the first one had just destroyed. A violent 2025. This year’s March has certainly shattered weather records with a total of 299 tornadoes in a single month, and experts point to ‘The Girl‘ as responsible for all this. This climate phenomenon has altered the Pacific jet stream over North America, creating a perfect breeding ground for supercells! By moving the humidity of the Gulf of Mexico to the north and encountering very persistent cold air, everything necessary was in place to have a true meteorological war. And it is no wonder, since at least 1,000 homes were damaged by this phenomenon. Its usefulness. Beyond the photography of scars, science seeks to anticipate the disaster. Researchers at NASA Langley Research Center They are using these satellite images and data on cloud patterns to refine prediction models that allow the population to be warned with a little margin (but not much). The objective right now is to gain 10 minutes’ notice of tornado warnings so that the population can be protected. And it is no wonder, since a scenario where an EF4 can erase a neighborhood in seconds, having 600 extra seconds is the difference between life and death for those who find themselves in the path of this scar.

There are 10,000 soldiers and unusual artillery pointing at the same place in the Caribbean

by

It all started under the pretext of “drug trafficking”but the amount of accumulated signals, troops and artillery that the United States has been adding around the southern Caribbean, indicate that the operation has slipped towards a coercion mechanism strategic to force accelerated eviction without a formal invasion. A combination of visible deterrence, explicit threats and preparation of windows of surgical action. In the background: Venezuela. Evolution of the objective. It we count last week. The US deployment began wrapped in the classic language of the fight against drug trafficking, attacking boats fast and reactivating bases with a technical pretext. It happens that the accumulation of gestures (B-52 with transponders assets bordering on the Venezuelan FIR, “ghost ships”, SOF helicopters training off the coast, and the trump admission that “he doesn’t want to play”) seem to have another purpose: the message It no longer seems to deny drug routes, but rather something more akin to overthrowing the Venezuelan regime. The public articulation (“Maduro is a fugitive”, “he must go”) and privately aligns military deployment with a logic of collapse rather than containment. Artillery as pressure. The volume of resources and troops from Washington that CNN reported in the last few hours and the New York Times through satellite data (thousands of soldiers next to the ARG Iwo Jimathree destroyers DDG guided missilesa cruisea SSN submarineairplanes AC-130J armed with hellfire, F-35 in Puerto Ricoairplanes P-8, MQ-9, ISR flights massive and reactivation of the Roosevelt Roads base) is disproportionate to simply hunt down drug boats, although insufficient to occupy Caracas. Is, according to analystsexactly the size that allows hitting nodes (command, radars, escorts, inner rings) without “going fully into” a war, and maintaining a credible “low-profile” escalation vector. American voices match in the Financial Times: “it is too much for drug trafficking, but not enough for an invasion”, and what is left in the middle is a luck calibrated pressure. One of the satellite images captured on October 17 showing F-35 fighter jets at the José Aponte de la Torre Airport in Puerto Rico The mystery of Venezuela. For its part, the Venezuelan Armed Force is eroded by maintenance and spare parts, but much less naked: there is S-300anti-aircraft artillery, MANPADS, F-16 and a million militiamen that cast serious doubt on the reputational costs if Washington crosses the kinetic threshold. At the same time, the national commanders they suspect leaks and purge loyalties, the Times said that they sleep rotating locations and change escorts. A pattern that reveals internal vulnerability and expectation of a selective coup, in any case, there does not seem to be confidence in defeating the United States. Colombia and something more. The dialectical escalation with Colombia (Trump has called Petro a “drug leader,” threats of cut funds and tariffsand rhetorical retaliation after a naval attack that killed a fisherman) reconfigures an alliance that until now was key for Washington: the same one that provided the 80% of intelligence in the area. In other words, the clash erodes the regional pillar precisely when the United States approaches the use of force threshold in Venezuela, expanding the diplomatic front and reducing its margins for sustained maneuver. The political window. While, Donald Trump’s administration acts against the clock: this posture sustained under a climate of war does not seem to be able to be maintained indefinitely and any accident can precipitate an unplanned escalation. Plus: Trump does not seem to focus the operation on normative criteria (elections or institutional guarantees) but rather to a result that he can declare as “victory,” which makes the margins of American rhetoric more flexible, but hardens the incentive for a spectacular blow. Military analysts warn that “over braking” could behead without transition and opening a vacuum, while the opposition replies that Venezuelan social cohesion reduces that risk. Thus, the gap between both hypotheses is precisely where the greatest American pressure operates today. Strategic test. In summary, the combination of visible military troopscredible threat of precision hits and a diplomacy that does not stop tightening the rope, define that kind of ultimatum phase but without a formal ultimatum. From that perspective, the outcome aims to depend less on the balance of fire than on the breaking point within the Chavista leadership and whether Washington decides to stop after a possible departure of Maduro, or explicitly pursues the “end of” as a regime. And while that ambiguity persists, the pressure aims to continue… while the Caribbean wonders for how long.

Two years ago, an asteroid exploded over France with unusual violence. What saved the French was their size

by

February 13, 2023. It was 4:59 in the morning when a violent explosion illuminated the skies of Normandynorth of France. It was not a ray, nor a missile. It was the end of a travel of millions of kilometers for a small asteroid called 2023 Cx1. Seven hours of notice. The 650 -kilogram rock had just a meter in diameter, so it had been detected only seven hours before impact. But the most disturbing thing was not his surprise arrival, but his behavior when entering the earth’s atmosphere. An exhaustive analysis published two and a half years later in Nature Astronomy He has revealed that, if the asteroid had been larger, the consequences of his extraordinary explosion could have been devastating. A high -risk meteor. Most meteorites are fragmenting as they descend through the atmosphere, but 2023 CX1 endured intact until it reached a distance to the ground of only 28 kilometers. At that point, the pressure made it explode like a pump. After traveling through space for about 30 million years, the asteroid released 98% of all its kinetic energy in a second fraction. And in a very concentrated region of the atmosphere, when it reached a dynamic pressure of 4 megapascal. It does not compare with Cheliábinsk. The 2023 CX1 behavior was radically different from that of the car whose explosion of 500 kilotons He broke windows and caused hundreds of injured in Russia in 2013. The one in France generated a spherical shock wave instead of cylindrical, concentrating much more energy and greatly increasing the area of ​​soil affected by overpressure. According to researchers, this type of abrupt fragmentation could cause much more damage than the progressive fragmentations of similar size bodies. The French were lucky that it was so small. More firewood for planetary defense. The analysis was based on an unprecedented number of observations after mobilizing the scientific and citizen community in those seven hours of margin. The prediction of the fall by ESA and NASA had a margin of error of less than 20 meters between the planned and observed trajectory, which in turn facilitated the recovery of more than one hundred fragments of the meteorite in the commune of Saint-Pierre-Le Viger. According to the CSICwhich participated in the investigation, this event confirms the existence of a new population of asteroids, type L chondrites, capable of these violent explosions. “These asteroids must be taken into account in the Planetary Defense Strategiessince they represent a higher risk for populated areas, “says Auriane Egal, first author of the study. With what we know today, perhaps the authorities activate evacuation plans the next time an asteroid of this type threatens us. Provided that detection systems do not fail, and detect the threat in time.
