take down a Russian ghost fleet without the need for humans

Europe has been dealing with the call for years “ghost fleet” Russian, a network of aging tankerspoorly insured and with opaque owners who have evaded sanctions, turned off transponders, manipulated routes and put European waters at risk with incidents, leaks and dangerous maneuvers. These ships have operated at border of legality to keep afloat energy income from the Kremlin, forcing Brussels to strengthen maritime controls and several coastal states to investigate suspicious incidents near critical infrastructure. The birth of an offensive. The night of November 28 marked a turning point silent but decisive in the war that has pitted Ukraine and Russia for almost three years. A few dozen km from the Turkish coast, far from the usual range of Ukrainian systems and in the heart of Moscow’s logistical rearguard, two Sea Baby naval drones (unmanned, guided by AI and armed with explosive charges weighing more than a ton) rushed at full speed against two oil tankers of the Russian “ghost fleet”the network of aging and opaquely owned ships that Moscow uses to circumvent Western sanctions. The hits against the Kairos and Virat not only showed a technological leap in the range and precision of Ukrainian naval drones, but also sent a strategic message to all actors in the global energy trade: any ship supporting Russian exports can become a military target, and kyiv is no longer limited by the geographic space of the northern Black Sea to impose that cost. The meticulous execution of the attacks (aiming propulsion and rudders to disable, not sink) reveals the extent to which Ukraine is trying to balance military effectiveness with the political risk before international partners, aware that it is hitting an economically sensitive terrain for Türkiye, Kazakhstan and several Western companies with energy interests. How the ghost fleet works. The so-called ghost fleet is one of the pillars that Russia has built since 2022 to maintain its income stream tankers, recruiting hundreds of tankers with decades of service, dubious insurers and convenience records, many of them under African flags like that of the Gambia. The Kairos and the Virat, pointed out by sanctions bodies from the United States, the United Kingdom, the EU, Switzerland and Canada, are perfect examples of this network: very old ships, with questionable maintenance, designed to operate in the legal shadows that allow real owners and routes to be hidden. Its function is key because oil continues to be the Kremlin’s financial key: only in October, Russia entered 13.1 billion dollars for sales of crude oil and derivatives, although the figure already shows a significant decrease compared to the previous year. Damaging these ships (and above all, showing that no part of the Black Sea is safe) turns each transit into a calculated risk. The ultimate goal it is erosive: increase insurance costs, slow down logistics, increase the risk perceived by intermediary companies and force them to reconsider their collaboration with Moscow. He sinking of the M/T Mersin off Senegal, although it is not proven that it was the work of Ukraine, it illustrates the growing deterioration of a fleet that operates with minimum standards. The transformation of the Sea Baby. The Sea Baby have established themselves as the spearhead of an unprecedented Ukrainian naval revolution. Their early versions acted as medium-range explosive platforms; but the updated prototype, shown by the SBU in October, has multiplied its capabilities: 1,500 kilometers of autonomy, high speeds, autonomous navigation supported by AI and up to 2,000 kilograms of payload. Now they can operate anywhere in the Black Sea, from Odessa to the Bosphorus, from Crimea to global oil routes. This expansion underlines an evolution with two simultaneous layers: Ukraine is destroying the historical Russian hegemony in the Black Sea, and it is doing no traditional boatswithout sailors and without risking lives, relying on a naval concept that Moscow has not managed to replicate with the same efficiency. The combination of drones, Western satellite reconnaissance, electronic intelligence and autonomous platforms makes the Russian navy look increasingly corneredforced to disperse fleets, reinforce escorts and operate with a caution that reduces their freedom of action. Geopolitical leap and message to third parties. That the blows occurred a few km from the Turkish coast is not a technical whim: it means that Ukraine has crossed a symbolic and geopolitical threshold. For the first time, it has attacked Russian naval infrastructure in areas where global trade, NATO and maritime law converge. The images verified by BBC show drones hitting ships that were assisted by the Turkish coast guard, in an extremely sensitive environment for Ankara. Türkiye reacted with a very low profilelimiting itself to putting out fires and rescuing crews, aware that openly protesting would go against its difficult balance between Russia, NATO and its own regional agenda. But the message is there: Ukraine is no longer limited to destroying Russian ships within the space that Moscow considered comfortable control; Now it can harass energy trade even when plying international routes. This reconfigures the calculations of insurers, shipping companies and states involved: even Kazakhstan protested after the Caspian Pipeline Consortium terminal was affected, underlining that the Ukrainian campaign is touching multinational interests. Hitting ships, but also infrastructure. One day after the attack on the oil tankers, the Sea Babies attacked the CPC marine terminal in Novorossiyskforcing it to stop operations. Is the third time In just a few months, Ukraine hits this crucial enclave. The emerging equation it’s clear: disabling ships is just one part; degrade the infrastructure that allows oil exports, another even more destructive for Moscow. Ukraine is applying a dual strategy that suffocates the Russian oil system at both ends: the ships that transport the crude oil and the points where they are loaded. The result is a predicted fall of 35% in Russian oil revenues in November and a fiscal impact that already force unpopular measures how to increase VAT or suspend payments to veterans, a sign that the Kremlin’s “war economy” is beginning to feel the accumulated pressure.

Lava rises hundreds of meters in Hawaii. Under it, a much bigger plan: reactivate geothermal energy

The heat from the depths of the Earth is in the news again. And not only because of the almost unreal images of Kilauea launching jets of lava hundreds of meters high on the Big Island of Hawaii. Also because, while the volcano chains increasingly spectacular eruptive episodes, the United States is rediscovering the energy that those same volcanoes hide beneath the surface. Geothermal energy had been in the background for years. Suddenly, it matters again. Quite a spectacle. First of all, the United States Geological Survey (USGS) has warned that Kilauea is preparing for another high-energy eruptive episode. However, these are not isolated episodes. According to ABC Newsthe volcano has already had 36 and 37 eruptive episodes since December of last year. In some phases, the fountains have reached 300 meters and in others they reached 457 meters, a height comparable to a 100-story skyscraper. Even so, the entire phenomenon remains contained. All activity remains within the crater, away from homes or structures. That does not detract from the power of the figures: according to the USGSepisode 37 expelled 6.3 million cubic meters of lava in just nine hours, at a rate of around 190 m³ per second. But behind the show, another debate is beginning to make its way. Hawaii’s untold potential. In fact, as the Hawaii Tribune-Herald recallsSince 1993, the state has had a commercial geothermal plant, Puna Geothermal Venture, located precisely in the East Rift Zone of Kilauea. The University of Hawaii estimates that this facility produces five times more electricity than one of the state’s leading solar parks using 80% less land. The problem is that Hawaii has never tapped into that potential. The reasons combine real volcanic risksexploration costs and cultural resistance of communities for which drilling is a form of desecration of Pele, the volcano goddess. However, the context has changed. Kilauea’s continued activity brings back to the table a question that seemed shelved: should Hawaii use the heat that fuels its volcanoes to power its electrical grid? A door that begins to open. The University of Hawaii has been insisting on it for years. According to their analysis, all major islands could have usable geothermal resources, although knowledge outside Kilauea remains limited. Your Play Fairway project, funded by the Department of Energyhas already drawn the first deep heat maps beyond Puna. The pressure is now political. According to the Hawaiian mediathere are three state agencies competing for funding to re-explore the island in search of new deposits. 80 million public dollars are requested to map resources, drill test wells and reopen the way to a geothermal expansion that has been stalled for decades. The plan includes drilling outside of Puna, on the Big Island, but also in Maui and Oahu, where the resources would be deeper. As the volcano flares up and spills lava in nine-hour episodes, Hawaii looks under its feet: not at the magma, but at the heat that drives it. America’s geothermal renaissance. This local turn coincides with a national renaissance. According to a report by WoodMackenziegeothermal investment in North America soared 85% by 2025 in the first quarter alone, with $1.7 billion in public funds. The reason is not in the volcanoes, but in technology. The analysis points out three innovations that are transforming the sector: According to that analysisthe United States could have 500 gigawatts of geothermal capacity, a figure capable of reconfiguring the country’s energy matrix. However, there is still more. The hidden engine: data centers and AI. As TechCrunch detailedthis underground energy could cover two-thirds of the electrical consumption of the new data centers that will be built in the United States between now and 2030. And the technology giants are already taking positions. In fact, the cases are beginning to multiply as is Meta has signed an agreement with Californian startup XGS Energy to generate 150 MW of geothermal electricity by 2030 using a closed-loop system that prevents water leaks. Also Google has done the same partnering with Fervo Energy. Geothermal energy is no longer a marginal experiment: it is an energy outlet for the infrastructure that supports artificial intelligence. The question left by the volcano. As Kilauea continues its choreography—inflating, roaring, and shooting lava to heights not seen since the 1980s—Hawaii and the rest of the country look downward toward the primeval heat pulsing beneath the crust. Where nature shows its wildest power, technology sees promise: a forgotten energy resurfacing as the United States the more you need electricity continuous, abundant and clean.

13 premiere movies and series to watch in December 2025 on Netflix, Prime Video, HBO Max and streaming

Good! Christmas right there and unless you work as Santa’s elf, everything indicates that you will be able to dig out the blanket from the attic where you have it and organize some good sessions with the stove, slippers and streaming. As these parties usually come loaded on the platforms, here are some ideas so that you don’t miss out on any news. Percy Jackson and the Olympians Among the many franchises that Disney found with the purchase of Fox was Percy Jackson, which had already given rise to two films at the beginning of the last decade that sought, like so many of the time, to find a new Harry Potter. Although they did reasonably well at the box office, their departure from Rick Riordan’s original novels earned them quite a bit of antipathy, which seemed to be moderated with a more faithful Disney+ series. Now comes the second season, where a teenager with a destiny bigger than he imagines travels across the United States fighting monsters and gods to return his lightning bolt to Zeus. On Disney+ from December 10 Mad Men – Complete Series There are series that never go out of style, and ‘Mad Men’ is, indisputably, one of them. After a time away from our screens (unless you subscribed to Lionsgate+), now you have the opportunity to binge the almost one hundred episodes of this satirical epic that perfectly portrays New York in the sixties. Donald Draper, executive of a major advertising firm, is the protagonist of this series that helps us understand each and every one of the vices of the society we live in now, sixty-odd years later. On Disney+ from December 14 The last outburst Is one of the best films in the history of Spanish cinema. Many say that it is the best: a mix of experimental cinema, vampire film and desperate and addictive love letter to cinema. Converted into a cult film, ‘Arrebato’ is the core of this unclassifiable (like its object of study) mix of documentary and fiction that investigates the strange black hole that the film represents for all those who see it and worked on it. ‘The Last Rapture’ follows the clues that would explain the disappearance of Iván Zulueta and his film, accompanied by Jaime Chávarri and the original actors of the classic, Eusebio Poncela, Cecilia Roth and Marta Fernández-Muro. On Movistar Plus+ from December 3 relay Among Movistar’s more or less unreleased releases, this thriller that seems to seek inspiration from the conspiracy thrillers of the seventies especially draws our attention. But updated, of course: now the target is anonymity in the internet age. Directed by the always reliable David Mackenzie, whom we remember from ‘Comanchería’, it stars Lily James, Riz Ahmed and Sam Worthington, and we will follow a scientist who has been fired after warning about the side effects of the project she was working on. But she has evidence that the company is hiding information and believes she is being persecuted. On Movistar Plus+ from December 26 good boy A simple and direct horror gem, practically silent, that in just 72 minutes tells a story told from the perspective of Indy, a dog who, together with his owner, faces supernatural phenomena in an isolated house. Continuously at the height of the dog, giving us a unique immersion in the story, the film avoids the typical anthropomorphic vision of the animal in a minimal budget experiment that plays with atmosphere and sound to create a feeling of constant threat. It took years to film, since the dog is the director’s real pet and is not trained to act. On Filmin since December 19 Zodiac Killer Project Only a killer like Zodiac could spark a documentary true crime like this one, where the important thing is, obviously, not the investigation and the identity of the criminal, but rather a deep reflection on the codes and topics of the genre. We will walk through the typical true crime scenarios, but stripped of all spectacularity, accompanied by a deep reflection on a completely saturated style and taking as a starting point, precisely, an abandoned documentary about the Zodiac Killer. On Filmin since December 26 F1: The Movie The movie that has turned around finances from Apple’s audiovisual division after a series of failures is this fast-paced sports film focused on Formula 1. We will learn the story of the most promising driver of the 90s until an accident is about to put an end to him. Thirty years later, he has become a kind of driver for hire who receives a proposal from a former teammate, owner of a Formula 1 team on the brink of closure. An authentic visual spectacle thanks to the realistic immersion in the races through first-person shots and effects without CGI tricks. On Apple TV from December 12 Fallout T2 One of the most popular science fiction series returns funny and praised in recent timesand also a production that has lifted the curse of video game adaptations, demonstrating that no project is sufficiently ambitious when it is done with knowledge of the facts. We also leave the first season at a very interesting point: Lucy searching for her father after being betrayed and the Ghoul searching for his family, who may have survived the Holocaust. And their steps take them to a mythical location. None other than New Vegas, legendary setting for the franchise. On Prime Video from December 17 Palm Springs Although it has been roaming around on all types of platforms for some time now, this cult comedy is always a delight that can be reviewed again and again thanks to how it reinvents the concept of a time loop with a contemporary tone and melancholic atmosphere. Andy Samberg and Cristin Milioti have perfect chemistry and together they go a step further than what we have already seen in classics like ‘Trapped in Time’. Here, Samberg is locked in a loop that repeats the same day over and … Read more

the price difference with gasoline is now almost zero

Bad news for drivers of diesel vehicles, who continue to be the majority in our country although they sell less and less. This fuel, which has traditionally been cheaper than gasoline, now faces a worrying future, and in fact the savings it previously offered are fading. It doesn’t stop going up. In the last five months the price of diesel has not stopped rising and in total its cost for the user has increased by 7% in this period. This upward trend is a setback for millions of users who see how the traditional economic advantage of their vehicles fades away little by little compared to gasoline options. Price gap closes. The most recent data from the EU Oil Bulletin, for the last week of November, indicate that the average price of diesel has stood at 1,456 euros per liter. That of 95 octane gasoline has not changed that much, and its appreciation in that time has been 2.1%, standing at 1,489 euros. The price difference between both fuels has been reducing in this second half of the year, and is now only 0.033 euros per liter, the narrowest margin since December 2023. Nuances. In reality, Spain’s situation is not exceptional, and in the EU there are already 11 countries – such as Austria, Belgium or Sweden – in which diesel is more expensive than gasoline. However, Spain remains one of the regions with the most affordable diesel, and is the fourth “cheapest” country in the EU, only behind Malta, the Czech Republic and Bulgaria. Russia and winter. Inés Cardenal, Director of Legal Affairs of the Fuel Industry of Spain (AICE), explained in El País the possible causes. According to her, Russia “is a large producer of refined diesel, the fuel most consumed in winter in Europe, and that has continued to put pressure on the market for three years due to the mismatch between supply and demand.” The US sanctions on large Russian crude oil producers They don’t help, of course. Diesel had an advantage. The truth is that diesel plays with a fundamental advantage in Spain: It has a tax burden that is 10 cents per liter less than that affecting gasoline, something that has led to its lower price. However Spain promised Europe a tax reform in exchange for continuing to receive European funds, and the idea is precisely increase the tax burden on diesel to equate it to that of gasoline. The surprise has already happened. In the last 20 years there have only been two times when the price of diesel exceeded that of gasoline. The first in 2008 due to the massive “dieselization” of vehicles in Spain. The second, due to the war in Ukraine, which caused diesel to be slightly above gasoline in March 2022 (€1.83/l vs €1.81/l) and remained above half a year. Uncertainty. Although the price of crude oil has remained relatively stable in the last year, European fiscal policies and the geopolitical situation point to a potential paradigm shift. It may not be a bad idea to prepare for a scenario in which fill the tank in a diesel vehicle no longer represents the savings of yesteryear.

The existence of lightning remains a mystery to atmospheric physics. Austria has given us a clue to solve it

It seems unbelievable, but in the middle of 2025 one of the most common and violent phenomena of nature continues keeping many secrets. This is the case of raywhich we know how to protect ourselves from and we know that Franklin had very right with your kite. But if we ask an atmospheric physicist what exactly detonates the first spark inside a cloud to start the download, you’ll probably shrug your shoulders. The discovery. We would expect the answer to this classic meteorology question in the sky itself, but in reality it seems to be in a laboratory in Austria. It has been here where they have achieved something that seems like magic: using lasers to trap microscopic particles in the air, and almost by accident, discovering a charging mechanism that could be the ‘missing link’ in the formation of lightning in our sky. What we knew. For lightning to strike, it is necessary that there is a monstrous electric field that breaks the resistance of air, something that has a name: dielectric breakdown. The problem is that when we measure the electric fields inside a thundercloud, the numbers don’t add up: They are too low to initiate lightning on their own. This means that scientists have long suspected that the secret was in the aerosols and ice crystals that collide within a cloud. And the theory is quite clear: if a small particle could accumulate enough charge, then it has the ability to create a micro-electric field around it so intense that it would start a chain reaction. The problem is that studying a microscopic ice grain in the middle of a storm is impossible, since we can be next to it and we cannot lower the cloud to the ground either. That is why this is where this research comes in, which has found a high-tech solution with optical tweezers. The experiment. To find the answer, a 532 nm green laser was used to make lift a silica sphere just a micron in diameter. But… Why? In this case, the initial objective was to measure forces precisely, but they encountered something very strange: the laser itself that held the particle was electrically charging it. Far from being a mistake, they realized that they had in front of them a perfect tool to simulate the atmosphere in miniature. It was no longer necessary to go to a cloud to analyze it. In this way, they began to charge a particle with so much static electricity that it caused a dielectric breakdown in the air around them, discharging themselves suddenly. They had literally created a controlled micro-ray in the laboratory. The authors of the study explicitly suggest that this system is an ideal model to study the electrification of aerosols and clouds. Its importance. Until now, studying these phenomena required getting into a storm-chasing plane or relying on computer simulations. But now we have the ability to simulate these conditions in a controlled way. And it is also ideal to understand why sometimes the sky seems like it is going to break in our own heads.

China aims to break records with the largest ice park in the world. And he has already begun to lift it block by block

At the end of November, in Harbin, the image is repeated every winter, with a scale that has not stopped growing in recent editions: cranes, machinery and workers begin to raise structures on a surface that weeks later will become walls, towers and slides made of ice. According to official dataconstruction is advanced this year thanks to the ice stored during the previous season and preserved for more than ten months. This material allows work to begin even before the river freezes completely again, with the aim of preparing an area that this winter will have 1.2 million square meters. Harbin Ice-Snow World It has grown from a local celebration to a seasonal theme park that rises again each winter. It functions as an enclosure with defined entrances, circulation areas, walkable structures and spaces to stay for hours, especially when it gets dark and the lighting changes the perception of the place. It is not just a setting for photographs, but a park designed to be walked, used and visited for a few weeks, while weather conditions allow it. When ice stops being landscape and becomes infrastructure Upon entering the venue, the experience is more similar to that of a theme park than a temporary exhibition. You can walk between buildings, climb platforms, slide down ramps or access areas prepared for snow activities. The architectural elements are not presented as immobile pieces, but as part of the route. For this edition, those responsible have announced spaces intended for ice fishing, cross-country skiing and collective snow gamesas well as an additional stage that will complement the cultural activities of the already usual Dream Stage. The proposal does not focus solely on showing structures, but on facilitating their use within a planned and temporary environment. Before erecting ice structures, Harbin already celebrated winter through local practices. Hand-carved ice lanterns began to be used in the city in the middle of the last century and gave rise to the first Harbin Ice and Snow Festival, held on January 5, 1985. indicate official pages. The jump to the current format came in 1999, when Harbin Ice-Snow World was created as an independent venue, with specific access and design. Since then, the evolution has been constant: more surface area, greater volume of materials, presence of machinery and planned construction processes. The park, under construction in November 2025 Harbin has turned winter into a source of economic activity. According to data released by Xinhuathe city received 90.36 million visitors during the last season, with estimated income of 137.22 billion yuan (almost 17 million euros), an increase of 16.6% compared to the previous year. Ice-Snow World does not explain these figures on its own, but it acts as one of the main focuses of attraction and as an element that concentrates tourist services, accommodation, restaurants and transportation during the weeks in which it remains open. The construction mobilizes technical profiles, operators and specialists in structure and lighting, while the opening requires personnel for visitor service, security, maintenance and tourist support. Many of these roles are temporary, but require prior coordination and planning. When comparing Harbin to other major winter events, such as the Sapporo Snow Festival in Japan or Quebec Winter Carnival in Canadathe difference is not only in size, but in structure. Sapporo distributes its sculptures in various urban spaces and Quebec combines culture, parades and outdoor activities, but neither of them functions as a theme park concentrated in a single venue, as occurs in Harbin. Harbin uses hundreds of thousands of cubic meters of ice and snow, according to official data, and builds walkable structures that are part of the route and not just the landscape. It is not so much a festival as a temporary recreational facility. Harbin Ice-Snow World has been integrated into the city’s tourism calendar as a seasonal facility. It is built every year, it opens for a few weeks and It is dismantled when temperatures no longer guarantee stability. This temporary nature does not prevent its planning: the prior storage of ice, the mobilization of workers and the associated services indicate that it is an organized activity and not simply a one-off event. The park functions as a generator of temporary employment, concentrates the winter tourism offer and channels activities that are subsequently complemented by the interior ice and snow enclosure, designed to operate all year round as an extension of the exterior park. There is no pretension of permanence, but of repetition adjusted to the climatic conditions. This repetition has allowed the consolidation of technical, logistical and tourist processes linked to winter as a seasonal economic resource.

the longest railway tunnel in the world

Megastructures have a what-do-I-know-what-do-I-know-what makes us love them. It makes perfect sense: They are colossal works that humanity has been doing for millennia and in which we increasingly use more and more sophisticated machinery. There is also a certain sense of competition, and if a few months ago Europe boasted of longest railway tunnel in the worldtoday we have to talk about an even more difficult one: one twice as long and underwater. It is the Bohai Strait Railway Tunnel. AND will be in Chinaclear. Dalian-Yantai. To the sides of Beijing are the provinces of Liaoning and Shandong. The first has 44 million inhabitants. The second, 101 million. They are two important nerve centers in China, but there is a problem: they are separated by the Sea of Bohai and the only way to get from one to the other is by ferry, which takes about eight hours, or by going around the bay on a 1,500-kilometer trip. Given the importance that the area was gaining, in 1992 the idea of ​​a connection across the strait arose that would link the cities of Dalian and Yantai. Although China has accustomed us to mega constructions in record timein this case the logistics were complicated and it was in 2012 when a research group was established under the supervision of the Chinese Academy of Engineering to see if it was viable and, in 2019, they began to talk seriously about the project. Specs. A structure that combined bridges, islands and tunnels – like the Hong Kong Zhuhai-Macao– those in charge of the project agreed that the best solution would be a single railway tunnel whose characteristics are… colossal: 125 kilometers in total, 90 of them underwater. Designed for trains traveling at a speed of 220 km/h. Built 80 meters below the seabed. Two main tunnels of 10 meters in diameter. The most important thing: of the eight hours by ferry or more than ten by car, the journey would take about 40 minutes. It is a considerable reduction in time that will help not only transport people, but also what is most interesting in the region: goods and commerce. Train>car. The price of the tunnel has varied over long of these years. The estimate a decade ago was 200 billion yuan, about 30 billion euros. Currently, it is closer to 300 billion yuan, about 40 billion euros. Everything to unite two of the most powerful regions of China in terms of trade and more than the colossal Three Gorges Dam. HE esteem that it would take about ten years to recover the public-private investment in the infrastructure, and the reason why the tunnel has been planned as a railway tunnel instead of a mixed one (cars plus trains) is for safety reasons. Bohai’s will be more than twice as long as the Eurotunnelso creating such a long underwater tunnel suitable for cars would be extremely expensive and complex as it would require adequate ventilation. Furthermore, in the event of an accident, emergency response would be more difficult. What there will be are shuttle trains that will allow both cars and trucks to be loaded. This is something that is already being explored in other parts of the world and, recently, we have seen it raised in the American transcontinental. Challenges. Now, it’s not going to be easy. The topography of the bay bottom varies between areas of just 10 meters to others that reach almost 90 meters deep. In addition, there are active faults in the area and it is a region with high seismic activity. In fact, it is close to the Tan-Lu fault, one of the most active in China, which implies a thorough study to adapt the structure to possible earthquakes. Ecology. On the other hand, the ecosystem. Apart from being a sensitive area in terms of earthquakes, the tunnel would pass through ecologically sensitive areas. It is the habitat of the spotted seal, protected in China, and also includes migration routes for both fish and birds. You have to wait seated. And if we speak in the future it is because the works have not started. For now, it is about a projectbut in recent months important steps have been taken. In early 2024, the Bohai Tunnel was included in several national strategic documents, and in May this year incorporated to the Development Plan of the Modern Comprehensive Transportation System of the 14th Five Year Plan. In these 30 years, steps have been taken studying the feasibility of the project and exploratory drilling, and more recently more and more voices have emerged that mention the need to promote this Bohai corridor. When will the works begin? It is not known, but 2026-2030 is consider as the window of opportunity for it. Either way, if it ends up happening, Bohai will not only be – by far – the longest underwater railway tunnel in the world: it will also be one of the largest tunnels, overall.

In the Nordic countries there is also a turn towards spirituality. Towards Odinist spirituality, specifically

In a forest outside Stockholm as evening falls, a dozen people raise horns of mead toward the sky as a priestess invokes Thor. There are no skins or horned helmets —That’s a Hollywood invention.—. Here there are mothers, office workers in light blue shirts, young people dressed in black, retirees, tattoos with runes and cookies in the shape of the hammer of the god of thunder. The scene, described in a report by The Guardiandoes not belong to any historical recreation, but to a real ritual: a blótthe pagan ceremony that was celebrated in Scandinavia more than a thousand years ago and that, against all odds, has returned with a vengeance. “In the most secular countries on the planet, the old gods are returning,” writes Siri Christiansen in his article. And he doesn’t exaggerate. In Sweden, Iceland, Denmark, Norway and Finland, thousands of people today identify with the pre-Christian religions of the north. It is not a hobby or a passing fad: they are officially registered religions, with priests, temples, rites of passage, their own cemeteries and an expanding community. Why, in the most modernized society in the world, is an ancient cult reborn? The answer is more complex, but it has a surprising sense of normality. An ancient faith for unstable times. The Nordic countries top all the secularization lists in the world. In Sweden, only 10% of the population attends Christian churches regularly. In Iceland 40% of young people believe that God does not exist. And yet, in parallel, religions that were believed to have been buried since the 11th century are growing. In Sweden, two state-recognized organizations —Nordic Asa-Community (NAC) and Forn Sed Sweden— have around 2,700 registered members, although their networks exceed 16,000 followers. They have twenty local subdivisions, hold seasonal blóts, ​​and attract up to 300 people at their national gatherings. In fact, this year they have managed to get the Government to approve the first pagan cemetery in more than a thousand years, in the town of Molkom, with fifty burial requests already processed. They are also raising funds to build a temple in Gamla Uppsalathe ancient religious capital of the Vikings. A map of active minorities. In Denmark, the Forn Siðr organizationrecognized by the State since 2003, It has about 650 membersalthough it is estimated that there are some 3,500 practitioners in the country. Since 2009 they have managed a pagan cemetery in Odense where thirteen people have already been buried. In Norway, Bifrost and Forn Sed Norge They bring together hundreds of believers and publish materials on rituals, ecology and tradition. Both groups They openly declare themselves anti-racist and they have expelled members with supremacist speeches. Furthermore, Bifrost openly declares in its section Rasisme that any sympathizer of supremacist ideologies “is not welcome.” In Finland, the panorama is more dispersed, but it is also older. The community Karhun kansafocused on native Finnish religions, was recognized in 2013). For its part, the Lehto association, founded in 1998brings together practitioners of Wicca, shamanism, Ásatrú and Nordic paganism in general. Iceland: the heart of the renaissance. If there is an epicenter of the pagan revival, It’s Iceland. There the organization Ásatrúarfélagið, founded in 1972was officially recognized a year later and today is the second religion in the country, with more than 7,000 active members in a country of 389,000 inhabitants. In Reykjavík they are building the first pagan temple in a millennium, a circular building of concrete, wood and natural light entering through an open dome. The project—designed by architect Magnús Jensson, a member of the community itself—will complete work next year. In addition, it will house ceremonies, libraries, banquet halls and the sanctuary where the blóts of the solar calendar will be celebrated. What are the rituals like? The heart of today’s pagan practice are blót, seasonal ceremonies honoring the gods and forces of nature. According to an ethnographic studythese rituals are generally celebrated outdoors—forests, mounds, historic areas—and include poetry recitation, toasts, music, and a large communal meal. In ancient times, blót included animal sacrifices. Today, Nordic associations have radically transformed the practice: there is no blood, the offerings are symbolic (mead, bread, fruit, ritual burning) and often include the burning of a banner made among the participants, as the same study documents. It should be added that there is some micro-communities (unofficial) who have debated resuming animal sacrifices, but represent a marginal and controversial minority within the movement. In addition to blót, these religions celebrate weddings, funerals, baby namings, and coming-of-age rituals. In Iceland, a play based on in the Eddic poem Skírnismála solemn and surprisingly contemporary rite. Wedding celebrated during the 2022 spring ritual in Sweden Who is behind? The question is who is behind the new Norse pagan. According to research—collected at EUREL, sociologist Jane Haug Skjoldli or Heimskringla’s analysis—, the most common profile of current Nordic pagans is: adults between 25 and 50 years old, high educational level, stable employment or urban middle class, interest in nature, ecology and local culture. In addition to progressive values ​​(most organizations are explicitly anti-racist). Many people do not identify strictly as “pagans” but as Heathens, Fornsedare, Animists, Nordic Polytheists, or Ásatrúar. It is a flexible, non-dogmatic spirituality, with an emphasis on practice and community rather than doctrinal faith. A rebirth with tensions. An inevitable topic is the relationship between paganism and the extreme right. During the 20th century, Viking iconography was instrumentalized by Nazism and, later, by white supremacist groups. Today, associations such as Forn Sed Sweden, Bifrost and Ásatrúarfélagið publish explicit anti-racist values ​​and expel—as the NAC did in 2017, according to The Guardian— to members who express xenophobic ideologies. A member of Forn Sed Sweden put it bluntly: “If you’re a Nazi, you’re not a pagan. You’re just a Nazi.” Still, tension exists: Viking symbols have become mainstream on the internet, and some radical groups continue to use them. This forces official associations to position themselves again and again. Is the Viking religion really back? Yes, but transformed. It is … Read more

China already has an army of 5.8 million engineers. His new plan involves accelerating doctorates

China has a plan to win the technology race, one that began more than 40 years ago when decided to invest in training millions of engineers. We have seen it in the signings of the Meta superintelligence teamwhere the vast majority are Chinese. Chinese universities have a new plan to further accelerate the attainment of doctorates, one that puts aside theory to focus on practice. What is happening. They tell it in South China Morning Post. China is implementing a new policy that affects STEM students pursuing doctorates. The title PhD or ‘Doctor of Philosophy’ is the highest academic rank that can be obtained and until now required the development of a thesis. With this change, led by Harbin University of Technology, engineers can earn the PhD degree with the development of real products and systems. First case. The first student to achieve the PhD based on practical results was Wei Lianfeng last September. He graduated in 2008 and joined the China Nuclear Institute, where he worked for more than a decade until he decided to return to university to pursue his PhD, which he earned for his results in developing a vacuum laser welding system. To evaluate their work, the court that attended the oral defense included industry experts. Why is it important. The training of technical talent has been a priority for China for decades and more recently they have redoubled their efforts. In 2022, the government launched a program to promote STEM education especially in strategic areas such as semiconductors and quantum computing. Among the key points of the plan was close cooperation between companies and universities for joint training. This measure is the culmination of this strategy and the recognition that theoretical knowledge is not enough to compete in the technological race, especially with US blockades of key technologies. This allows China to solve the bottleneck in graduating higher-ranking engineers; It is not only about training more engineers, but about training them as soon as possible and with solutions that can be applied to the real world, instead of theses that are hundreds of pages long. STEM Power. The push to train engineers and scientists is part of a long-term government plan that began in the post-Mao era. And the plan is going from strength to strength. If we focus only on doctorates, according to data from 2023, China awarded 51,000 doctorates (PhD) in STEM careers, while the US was at 34,000. The projection at that time was that by 2025 the figure would rise to 77,000. In terms of total figures, In 2020, China was already the country that produced the most STEM graduates throughout the world with an abysmal difference: 3.57 million compared to the 2.55 million that India produced or the 822,000 in the United States. At the moment China already has 5.8 million graduates and it is estimated that more than 40% of all graduates choose a STEM career.
