four months at sea, kilometers of celluloid and a Trojan horse the size of a building

We already have here the first trailer for ‘The Odyssey’ by Christopher Nolan, which, as expected, offers us an adventure that moves away from the environments that the director has frequented until now, but which nevertheless has a good part of the house’s trademarks: musical fanfare, impactful images and dense and solemn atmosphere. a genuine deli for devotees of the director. After releasing a six-minute prologue a week ago Exclusive to 70mm IMAX theaters, this new trailer takes us to the immediate aftermath of the Trojan War: a devastated battlefield where Odysseus, played by Matt Damon, kneels before a fully armored Agamemnon (Benny Safdie) and which some critics have already pointed out as unequivocal proof that historical rigor is clearly not going to be one of the film’s priorities. From there, pure icons of classic adventure: the hero and his soldiers crossing forests, navigating rough seas and entering dark caves. Damon’s voiceover tells that “after years of war, no one could come between my men and home. Not even me.” Significantly, we barely see Odysseus on screen. The trailer gives a good account of Nolan’s visual ambition: we see the Trojan horse being dragged from the sea by hundreds of unsuspecting Trojans, and how the warriors inside the gigantic structure experience it. We see a giant creature at the entrance to a cave, perhaps the cyclops Polyphemus. We see ships suffocatingly tossed about by real waves. An ambitious odyssey ‘The Odyssey’ represents an unprecedented leap in the use of the IMAX format. It is the first film in history shot entirely with IMAX cameras.something Nolan has pursued since he began incorporating the format into action sequences with ‘The Dark Knight’ in 2008. Until ‘Oppenheimer’, technical limitations (excessive noise, prohibitive weight, difficulty capturing dialogue) prevented its continued use. But for ‘The Odyssey’, IMAX developed a new generation of cameras 30% quieter and considerably lighter, making full filming viable. Principal photography lasted 91 days between February and August 2025touring Morocco (Aït Benhaddou to recreate Troy), Greece, Italy, Scotland and Iceland. The most reckless: Nolan spent four months in the open seawith the entire cast rolling on real waves. The budget amounts to $250 million, making it the most expensive film of his career. Nolan explained. that sought to identify absences in contemporary film culture. He concluded that Greek mythology had never received the big-budget Hollywood treatment with full dramatic credibility. Furthermore, he states, The Odyssey by Homer contains elements of horror, mystery, romance and thriller simultaneously. It is not a genre, it is the matrix of all genres. It is clear that Nolan wanted to put the emphasis on the physical: real ships almost submerged in the sea, armies of extras, the Trojan horse… at the moment we do not see the abundant mythological creatures that the story has (the Cyclops, the mermaids, the sorceress Circe), but possibly they have sought to contrast with the realism of the rest of the story. And we still have to see the bulk of the star cast (Zendaya, Robert Pattinson, Charlize Theron, Lupita Nyong’o, Mia Goth…). This Odyssey has only just begun.

A dog was lost in 2021 in the United States. Five years later it has appeared 3,700 kilometers from his home

by

In recent years we have seen how the algorithm has taken over Christmasand Netflix to the head of the film industry competes to offer the most emotional miracle of the year, stories designed to reconcile us with chance, hope and those impossible endings. But this time, the story that best fits that mold does not come from a script or a streaming platform, but from real life, far from the screens and without special effects. The loss. The story has been collected by US media this weekend. Apparently, during almost five yearsPatricia Orozco lived with an unanswered question. Since Choco, the dachshund mix dog that he had adopted in 2016, disappeared in May 2021, his memory remained present in our daily lives. The uncertainty was constant: if he was still alive, if someone cared for him, if he had suffered. After months of posters, calls to shelters and no clues, the disappearance turned into mourning and a silent renunciation of having a dog again, as if accepting another company meant admitting that Choco would not return. The impossible message. Everything changed with an unexpected message from a microchip company. Choco had appeared, but not near Sacramento, where Orozco lived, but rather more than 3,700 kilometersin Lincoln, Michigan. At first, the woman thought it was Lincoln, California, just half an hour from her home. Surprise turned to disbelief when he realized that his dog had crossed practically the entire United States without anyone knowing how or when. Choco had been found tied to a fence in front of to a shelterand the photos confirmed what seemed like a mistake: it was him. The problem of bringing him back. The initial joy gave way to logistical anguish. With two small children, one of them barely four months old, Orozco saw no way to travel to pick him up. A message on social networks It activated an unexpected chain of solidarity. Volunteers, protectors and anonymous people began to look for solutions, from affordable flights to km donations (miles in USA). The possibility of someone traveling in his place took shape when Penny Scotta volunteer accustomed to complicated rescues, offered to make the trip. Orozco with his dog Choco, almost five years after he disappeared from his home in May 2021 A silent journey. The Washington Post told that Choco’s return was a small aerial odyssey. Scott flew from California to Detroit with stops and delays, picked up the dog thanks to the help of local volunteers and crossed the country again with the. A missed connection forced him to spend almost fourteen hours at the Chicago airport, where Choco, calm and docile, walked on his leash among travelers without a single complaint. For those who accompanied him, that behavior seemed to confirm that, despite everything, he was still the same calm and affectionate dog. The mystery of time. In the background of this most “Christmas” story, the great question: Nobody knows how the hell Choco ended up in Michigan or who he lived with during that time. The only thing that is clear is that he traveled through an entire country, far from the sunny climate that he had always known and that, according to its ownerI hated to leave. Now, at eleven years old, the dog had aged, but he had not lost his curious and affectionate character, the same one that led him to run away every time he found an open door. Return home. Finally, on December 3rd Choco came back to Sacramento. The reunion was immediate and left no doubt: when he got out of the car, he walked directly towards Patricia, as if he had never left. The same home from which he escaped years ago became his refuge again, yes, now withwith more precautions: a double door and the determination not to repeat history. For Orozco, the moment was unreal, a mixture of disbelief and relief that he still finds difficult to assimilate. A network and an idea. Beyond the happy ending, the story left a clear lesson. The microchip was the key piece that allowed us to close a circle that seemed broken forever, but so was the network of people who, without knowing each other, decided to act. Rescuers, donors and volunteers demonstrated that even after years and thousands of kilometers, a loss can be transformed into a reunion. For Patricia Orozco, there are not enough words to describe it: what happened, insistcan only be called “Christmas miracle”. A story with a happy ending that could be perpetuated on the big screen. The story of Choco and Orozco has all the ingredients to make the next Christmas list… in the home of the algorithms.

Less than 150 kilometers from Taiwan, the US does not stop accumulating missiles. It’s the closest thing to preparing for war.

by

For some time now, the Taiwan position in it strategic balance global has become one of the main axes on which power competition is articulated between the United States and China. The island not only represents a point political identity for Beijing or a symbol of democratic commitment for Washington, but also a decisive geographical node in the military architecture of the Pacific. and then there is a narrow between both. The distances. Maritime access to the island, the air routes that surround it and the narrow strip of water that separates it from the Philippines and Japan define a good part of the board in which it is decided how far project Chinese strength and to what extent it can be contained from the outside. Thus, the crisis that is emerging is not made solely of declarations or doctrines: It is made up of specific islands, narrow maritime corridors, and political decisions made in small communities that suddenly become geopolitical borders. The war strait. It counted on a extensive Reuters report that the chain of continuous military exercises and the missile deployment anti-shipping in the northernmost islands of the Philippines reveal a US strategy that assumes that control of the Western Pacific straits is decisive in preventing the Chinese navy from operating freely in the open sea. And at that point, the province of Batanesuntil a few years ago a quiet territory dedicated to fishing and subsistence agriculture, has become a point of critical importance, due to its position in the extreme south from Bashi Channelthe narrow sea lane that connects the South China Sea to the western Pacific. Bashi is located between Mavulis Island and Orchid Island The arrival of an arsenal. The establishment of a rotating military presencebut practically permanent, with deployments of mobile missile systems capable of blocking the passage of surface ships, has transformed this territory into an essential component of the so-called First Island Chainthe containment line that the United States, Japan and the Philippines intend to maintain to limit China’s ability to influence beyond its coastal waters. Local populations, aware of the historical precedent from 1941live in fear of seeing how their daily lives can be suddenly interrupted by the logic of deterrence or escalation. Liaoning exercises in the Pacific The uncertainty of the Philippines. The Manila government operates in the paradox of a country that does not want to be dragged into a war, but that recognizes that geography makes inevitable any implications in the event of a conflict in the Taiwan Strait. The administration of Ferdinand Marcos Jr. has unambiguously reopened military cooperation with the United States, granting expanded access to bases in Luzon and reinforcing the number and duration of joint exercises. Given the possibility of an attack or a blockade on Taiwanthe Philippines is preparing not only for defense operations, but for the forced return of tens of thousands of Filipino workers from the island. The prospect of a sudden influx of refugees, disruptions to supply routes and the need to operate under conditions of scarcity have led provincial authorities to raise contingency plans agricultural and logistical processes that return daily life to a state of cautious alert. China and reunification. For Beijing, the Taiwan question is presented as an internal matter which does not allow external negotiation. The Chinese leadership maintains that reunification is a historic address that sooner or later it will come to fruition, and that any foreign intervention constitutes an unacceptable violation of its sovereignty. Hence, the US military presence in the Philippines, the deployment of missiles and the intensification of exercises are interpreted by China not as defensive measures, but as deliberate attempts to restrict their margin of action and condition their ability to respond. The increase in Chinese naval operations through from Bashi Channelthe presence of aircraft carrier groups in the western Pacific and low-intensity pressure tactics against Philippine patrols are part of a carefully calibrated game of signals. Washington’s ambiguity. This week, Donald Trump has reiterated that Xi Jinping knows the consequences of an attack on Taiwan, while refusing to specify whether the United States would intervene militarily. This gesture of opacity, faithful to the doctrine of strategic ambiguity, seeks to simultaneously maintain deterrence against Beijing and the control over decisions of Taipei, preventing the island from declaring formal independence that could accelerate the clash. The difference with respect to the previous government’s approach is one of tone rather than substance: if Biden tended to explicitly verbalize the defense of Taiwan, Trump shifts the emphasis toward risk perception by Chinese leaders. Ambiguity not only preserves diplomatic margin; It also avoids automatically locking the United States into open war if an unexpected escalation occurs. Key islands. As it is, preparation for a possible conflict over Taiwan is not happening in abstract power centers, but in island territories where daily life depends on supply ships and where every Pacific wind brings with it the memory of past conflicts. The expansion of presence US military in the Philippines, Chinese pressure to break the limits imposed by the island chain, and Washington’s calculated ambiguity form an unstable balance that is already changing life in those communities. The future of the region will not be decided only in great summits diplomatic, but in the capacity of a few narrow territories to become a barrier, access or trigger for a greater change in the global order.

8 kilometers of ice have been lost in two months and researchers only agree on one thing: it is something to worry about

by

Predict their future the antarctic glaciers It is undoubtedly a great challenge for science, but the most important thing above all is to know How will it affect global sea level?. The worst of all is that the latest news we have at our disposal is not at all positive, since the Hektoria glacier It has retreated 8 km in just two months, which is an unprecedented speed in the modern era. Where we start from. Normally, the retreat of glaciers It is measured in hundreds of meters per year. It is one of the clearest metrics we have to be able to ‘measure’ global warming, and that is why now what a team from the University of Colorado Boulder has just recorded on the Hektoria glacier, on the eastern peninsula of Antarctica, plays in a completely different league. The measurement. In just two months during 2023, the Hektoria lost almost half of its mass. In total, 8 kilometers of ice disappeared. A speed of collapse that has never been seen in modern history and that, according to the authors of the study, is more typical of the end of the last ice age. Something that doesn’t add up in this case. Hektoria is relatively small by Antarctic standards (about 300 km², less than the city of Malaga), but its collapse was so sudden that it left researchers stunned. A coincidence. Ironically, the research team wasn’t even studying Hektoria. They were analyzing satellite and remote sensing data for another project when Ochwat realized that the glacier had essentially disappeared from the images. The measurements. This is where technology comes into play. The team had to combine data from multiple satellites to understand what had happened and, above all, how quickly he did it. “If we only had one image every three months, we couldn’t say that the glacier lost two and a half kilometers in two days,” explains Ochwat. In this case, by combining images from different satellites you can fill in the time gaps and confirm with evidence in hand how quickly the ice has been melting. But the key was not only in the images. They also used seismic instruments that have the ability to detect a series of “glacial earthquakes” that occurred exactly during the period of rapid melting. And these earthquakes are not measured for the sake of it, but to confirm something crucial: the glacier was anchored to the bedrock (and not floating) just before breaking. This is fundamental both for science and for the entire planet, since ice that is floating (such as an ice shelf) does not raise sea level when it melts, any more than an ice cube does in a glass of water. But ice that rests on land (or anchored to a seabed) and falls into the sea does contribute to the global rise in sea level by increasing its volume. Your Achilles heel. The collapse was not due to simple superficial melting. The cause was topographic, since many Antarctic glaciers rest on deep canyons or underwater mountains. The Hektoria, however, had the misfortune of resting on an “ice plain”: an area of ​​bedrock that was exceptionally flat and below sea level. This flat topography caused a gigantic section of the glacier to begin floating all at once, rather than gradually. The moment the glacier lost its anchorage to the ground (its “line of support”), it was exposed to the forces of the ocean, and therefore everything began to advance very quickly. The process was brutal, since it all began with the warmest ocean water that seeped underneath and began to open cracks from the bottom of the glacier upwards. At the same time, the glacier already had cracks on the surface. Eventually, the lower and upper cracks met and the glacier literally disintegrated. A warning for future glaciers. The Hektoria case is a first-rate warning. Scientists know that there are numerous glaciers in Antarctica that also rest on these types of ice plains. Until now, it was thought that their collapses would be centuries-long processes. Hektoria shows that they can be months, which should set us off due to the implications it would have on sea level. And while the collapse of a small glacier like Hektoria won’t dramatically change global sea level, it alone does demonstrate that a rapid collapse mechanism, until now theoretical or believed to be typical of past geological eras, is perfectly possible today. If this same mechanism is activated in much larger glaciers, sea level rise could accelerate very considerably and much sooner than expected.

The countries with the most kilometers of high-speed train, displayed in a graph with a brutal dominator: China

by

The train is the backbone of many countries. For centuries it has been key to mobility in Europe, in Japan it is essential, China has experienced a railway revolution and even the United States or Latin America begin to bet on passenger mobility by train. However, it is one thing to have a railway and quite another to have a rich high-speed network. And this graph shows the countries with the most kilometers of high-speed trains and their plans for the future. China, undisputed queen. The Olympics They are an event in which countries “sell” themselves to the worldbut in the case of China, it involved a profound renovation of its infrastructure. It was in 2008 when China launched its high-speed railway line: barely 120 kilometers between Beijing and Taijin, and 17 years later, it is the country with the most kilometers of high-speed lines in operation. According to the data of World Population Review and as we can see in the graph prepared by Visual CapitalistChina has more than 40,000 kilometers of tracks on which its trains go at 250 km/h or more. They have another 12,800 kilometers under construction and more than 11,000 planned. In total, some 64,000 kilometers of high-speed rail. In addition, they are moving forward to make their network the highest speed thanks to the maglev advancesmagnetic trains, with tracks that already link cities like Beijing and Shanghai to speeds of more than 430 kilometers per hour. And it is this network that is putting the airlines in check. Spain and Japan. The train is vital in a country as huge as China and the numbers speak for themselves, but there are two other countries that, without being the ones with the most kilometers in total (operational, under construction and planned), complete the podium of those with the most high-speed kilometers currently operating. There are no surprises here. Spain has a total of 5,632 kilometers of high speed, of which more than 3,700 are already operational, followed by China the country with the most kilometers of high speed currently holds. There are another 1,040 kilometers under construction and another 862 kilometers planned. For its part, Japan, another example when we talk about fast trainshas a total of 3,700 kilometers divided into 3,050 operational kilometers, 402 under construction and 193 planned. Promises, promises. At a time when the train is emerging as the alternative to international flights, especially to low cost and among short-distance points, it is striking that, in reality, there are no more countries with high-speed lines. In Europe, apart from Spain, France, Germany, Sweden, Finland or Italy, they have hundreds of operational kilometers, but outside of the ‘Old Continent’ and cases like South Korea, things are very different. For example, India. It is the second country in the graph, but of the 8,000 total kilometers, only 508 eare under construction and the remaining 7,400 are planned. They do not have high speed, and the same thing happens in Egypt (with 3,400 kilometers planned), Australia (1,700 planned) and European countries such as Latvia, Estonia, Norway or the Czech Republic: all with plans to create high-speed lines, but not one operational kilometer. America. And if in China the train is essential due to its dimensionson the American continent we should think that things are the same. And no, not at all. The United States, a gigantic country, has only 735 kilometers of high speed, 273 under construction and almost 5,000 planned, but nothing more. Spain tried to bring the AVE to the North American country and there are demands for high-speed trains to expand, but their internal mobility continues to have the plane as the protagonist. Canada has 1,500 kilometers planned and not one kilometer built, Mexico is in the same situation with 210 kilometers on the table, Brazil the same with 510 kilometers planned and Argentina does not even appear on the graph. But, although high speed is complicated on the continent, the truth is that there are many plans to expand the railway network, even creating international trains that go from one ocean to another, like the one planned between Brazil and Peru. And who is behind many of these projects? Well, who has gained experience at a forced pace in recent years ‘pulling’ thousands of kilometers of tracks: China.

Thus they can affect our health fires that occur thousands of kilometers

by

The summer of 2025 has been marked not only by extreme heat waves, but also by numerous high range fires, fires that were charged At least eight lives. The fires not only kill with their flames, some of the people died as a result of accidents related to their extinction. However, large fires can also have a range that goes much further, and that was the case of Canada’s fires of 2023. Transoceanic risk. A new study has pointed out That the impacts on the health of the population of forest fires that ravaged Canada in the summer of 2023 not only reached vast areas of North America, also to other continents, including Europe. The fires of 2023. Canada suffered in 2023 the worst fire season that is remembered in the country. They occurred More than 6,000 fires that razed with about 150,000 km², a larger area than we would obtain by together Castilla y León, Extremadura and the Community of Madrid. The fires were of such intensity that the smoke The sky stained orange from New York City. However, the winds moved the smoke and volatile particles that toured thousands of kilometers to reach our continent. Exposed to pollution. According to the team responsible for the study, Canada’s fires caused important Picos in concentration of particulate matter 2.5 or PM2.5, small volatile particles of a diameter less than 2.5 microns. This resulted in a worsening in air quality. According to estimates, at the global level the concentration in the air of this type of particles grew by 0.17 micrograms per cubic meter of air. The same estimates indicate that about 354 million people in Europe and North America were exposed to PM2.5 levels above the limits established as insurance by the World Health Organization (WHO). Premature deaths. The study estimated that, adding these factors, the flames caused between 3,400 and 7,400 deaths acute in the American continent. However, the impact was beyond, and they point out that the number of chronic deaths was even greater: between 37,800 and 90,900 taking into account both North America and Europe. The details of the study have been published In an article In the magazine Nature. A growing problem. The fire scale in Canada can be unthinkable in Europe, but the study serves as a reminder that the risks involved in forest fires go far beyond the reach of the flames. Especially at the close of A season that has been primed with our environment and whose consequences are probably not only noticed in our forests, but also in our health.

There are already robots running 1,500 meters at 13 kilometers per hour. It is the result of China’s robotic muscle

by

Last weekend, Beijing hosted the first “Olympic Games” for humanoid robots. Held in the National Speed Skating Ovalthe Olympic track built for the 2022 winter jjo, the three -day event allowed the attendees to see football, table tennis, boxing, martial arts and Athletics tests. In tests and exhibitions They participated dozens of Humanoid robots belonging to both private companies from 16 countries and 280 teams from universities and, although there were more or less fun moments, which has gone around the world is that of the Unitree robot on the athletics track. We can see it in this video: In this competition, the robots were not in their air, but were being operated by humans with remote control. That does not take merit to the fact that Unitree’s H1 model I got a speed record when completing 1,500 meters in a time of 6 minutes and 34 seconds. Its speed reached 4.78 m/s, exceeding the previous 3.3 m/s mark that held a few months ago and eclipseing the 2.5 m/s that the Boston Dynamics Atlas. And, in context, although it is much slower than Jakob IngebrigstenNorwegian that has the 3: 29.63 mark, it was also faster than many non -professional humans. But what is giving what to talk about, for the “fun” of the moment, was when that same H1 he ran over an operator of another robot who, Next to the Unitree model, I had nothing to do. In the end, as the human operators run next to their robot, when they relieve the control, the H1 operators mislead for a moment and ended up overwhelming the rival. Yellow card, if they ask me. But here the interesting thing is that these Olympics for robots, more than something fun or colorful, was a muscle demonstration to the entire world. That the ‘gag’ does not prevent seeing the forest Robots such as those of Unitree have artificial intelligence systems, and even internal language models, to perform the actions for which they have been trained. H1, without going any further, has been trained with a Honor property. The ‘ruling’ in the 1,500 meters test that resulted in the outrage was due to what was commented: they were not autonomous, but controlled by an operator. However, these Olympics served to demonstrate the versatility of a new generation of robots in which many countries have interest, but that China has become a national priority. The Asian giant is following an extremely ambitious national strategy with a goal: to become a world leader in short -term humanoid robotics. With the so-called ’14th Five-Year Plan for The Robotics Industry’, the government He set goals in 2021 with the idea of annual growth of more than 20% in the robotics sector. This year the First national standards For these robots, a regulation that covers from environmental perception and movement control to the planning and execution of tasks. And, for all this, it has created a state fund of almost 140,000 million dollars for technological startups, and Unitree is one of the spoiled by the Government. HE wait that the country produces more than 10,000 humanoid robots this 2025 and even They are creating “schools” in which these machines are trained in specific tasks such as cleaning, kitchen or series manufacturing. The purpose is that they are capable of perform tasks that require fine mobility. In the “Olympics”, apart from more conventional sports tests, medication classification tournaments, material manipulation and cleaning were held. Come on, it was a window for companies to show achievements that are going to leave in all media, such as the Unitree record, but also to be seen to what extent is the specialization of these robots. China considers that these humanoid robots are “The next great technological revolution” After smartphones and electric vehicles, and are an essential tool in the industry, but also to compensate for the Demographic decrease of some countries who are suffering to find workers in certain sectors. And there are several cities in which universities and startups are investigating in humanoid robotics, but the hard core of investment and leadership in China is made up of Shanghai, Shenzhen, Beijing, Suzhou and Guangzhou, agglutinating the largest number of companies and industrial parks for the development of robotic projects. In the end, the ‘World Humanoid Robot Games’ or events such as the Robot World Football World or the Boxing championshipsThey are nothing more than a showcase to test the abilities of robots that, in China they are already living with humans. For example, the Roboperros Guide for blindthose who are “living” in the subway distributing packages to feeding stores or those who perform tasks of Hospital care and care for older people. Returning to the Olympics, the most amazing thing is that Unitree ensures that those 4.78 m/s of their H1 have already been surpassed in internal tests.

Polestar has broken a record of autonomy in electric cars circulating more than 900 kilometers. Obviously there is a trick

by

935.4 kilometers without recharging the battery. That is the record that has achieved a Polestar 3 conventional – in its version of a single engine – thus demonstrating that it is possible to make very long trips without going through a recharge point. The secret is from the record is obvious, yes. Superdespace. For achieve all those kilometers The technique was simple: go very slowly. In fact, the average speed was less than 40 km/h, and took no less than 22 hours and 57 minutes to complete the task. The publicized autonomy by Polestar for this model in its unique motor version is 706 km, so here they managed to lengthen it 32.5%. Three professional drivers. The tests were performed in the United Kingdom, where three drivers specialized in efficient driving were turned to achieve that milestone. The final consumption reached was 12.1 kWh per 100 km, which represents a saving of about 40% compared to conventional driving. Without tricks. This Polestar 3 achieved that autonomy without using special equipment: both the car and the wheels were the same as one obtains When you get the concessionaire car. However, it is possible to go further if some modifications are made. If you also have the car, you can go even further. A few days ago Chevrolet modified A WT Silverado truck and put a huge 205 kWh battery (the Polastar 3 is 111 kWh). They also placed old wheels with overpressure and 40 drivers turned to drive it around Detroit. They managed to travel 1,704 km with a single load, and as in the case of Polestar 3 the average speed did not exceed 40 km/h. The consumption on that journey was 12.7 kWh at 100 km, an equally remarkable figure in which yes, influenced that they had the air conditioning without working for almost the entire route. Baja is also worth it. In July a Lucid Air Grand Touring He got his particular Guinnes record When traveling 1,205 kilometers with a unique load. The car has a battery with the same capacity as that of the Polestar 3 (111 kWh), and toured the distance between St. Moritz and Munich. Although the car was a conventional model, the lucid benefited from both efficient driving and the energy regeneration system in braking and slopes: that route was full of them, but it was also descending mostly. The key is not the battery, they are the consumption. Although obviously the battery capacity influences the autonomy of electric cars, further influences the consumption of each model. The Mercedes Vision EQXX for example achieved a record prior to the Tour 1,010 km without recharging at 79.4 km/h on average… and another 392 kilometers had left in those conditions. The secret is that this approval model 7.4 kWh consumption at 100 km, while for example a tesla 3 rear -wheel drive homologous 13.2 kWh at 100 km. Aerodynamics helps, but if things are added to consumption as an efficient driving and low speed, those figures rise significantly. Absurd records. Although all these records are striking, they are also a marketing exercise for companies that logically try the same thing: that they talk (well) of them. Here we have messages that are also even absurd: going at 40 km/h for 23 hours has its reward in this case, but in real life it would be absolute torture. The practical uselessness of these records – not only that of Polestar – is the same as the one who tells us about how The Xiaomi Su7 beat all its competitors In Nürburgring last year: none of us are going to those speeds or drive in those circuits, but speed records are always striking. Putting these vehicles to the limit is fine, but it is important to contemplate these records with perspective.

Chrysalis, the impossible ship 58 kilometers long to transport 2,400 people to next Centauri

by

Exodus through space is a recurring theme in science fiction. It doesn’t matter if it’s literature (‘Aurora’), cinema (‘Wall-e‘) or video games (‘Mass Effect Andromeda‘), the idea of a huge ship that transport a lot of people that become inhabitants of a planet on the other side of the universe is as fascinating as utopian. But at some point you will have to get to work, and there are those who have had an idea: a 58 -kilometer ship for Bring Humanity to Alpha Centauri. His name is Chrysalis, and the duration of the trip will be 400 years. Chrysalis project. Within the ‘Project Hyperion Design Competition‘, a group of Italian social engineers, scientists and architects They have designed Chrysalisa ship of about 58 kilometers in length with a cylindrical and multicapa architecture. To simplify, it would be like a Russian, but elongated doll, with a concentric core and layers that would have differentiated areas for: Production. Life. Industry. Storage. Would have artificial gravity achieved by constant rotation of the entire cylinder and the idea is that it can transport 2,400 passengers to Next bthe most promising exoplanet of the system. There they would disembark and could start colonizing the territory after a 400 -year trip. Estimated construction time? 20 to 25 years. Layers. It would be like a huge city and remember The Line, the Saudi Arabia macroproject. Throughout those 58 kilometers and depending on the layer, areas destined for food production, forest biocservation, community areas with parks and facilities such as schools, hospitals or libraries, as well as habitable modules, industrial areas and an external ring dedicated to storage. The heaviest jobs would be operated by robotsand it will not be the only thing, since the plan includes a combined governance between humans and artificial intelligence. No cryogenization. Something that we usually see in these science fiction works is that the crew criotic so as not to die during the trip, but in the case of Chrysalis, there would be no option. Throughout those 400 years, several generations will pass, being a task for all those that fail to reach the goal. To avoid tensions due to the shortage of resources, births would be controlled to the millimeter, maintaining the population within the sustainable limit that the installation can provide. Recycling is contemplated as a vital option and, to give energy to the entire complex, nuclear fusion reactors will be used. Crew preparation. In addition to the fact that everyone who embark on Chrysalis will not see their new home on the mainland, it must be taken into account that virtually no one of those who embark on the mission at first will set foot on the ship. The reason is that it is estimated that one of the most crucial part of the trip, also the most radical, will be the preparation for it. In addition to having psychological support and having a careful strategy for 2,400 people to live in such an environment, before leaving the training will be given for 70 or 80 years In Antarctica. That first (and almost second) generation will face the conditions of isolation and extreme confinement that they will experience during the journey. It will be part of the second and third generation that, finally, are on their way to next Centauri b. Housing modules. There would be one and two floors Do not make illusions. Now, the ‘Project Hyperion Design Competition’ is an initiative with an objective: to seek a spacecraft capable of taking some thousands of humans to a habitable exoplanet In an interstellar trip of several centuries, so it is only a conceptual project for several reasons. The first could be ethical, since training will be devastating and, in essence, the entire trip is an evolutionary experiment with a large -scale controlled population, which means this Mental health levelidentity and perception of time. The second … because the technology to make it reality escapes our understanding right now. Only the fact of need Fusion reactors (that We are investigatingbut we have not yet developed), leave this experiment as something exclusive to the science fiction field. Although, yes, The document It is tremendously explained. Images | Canva (presentation of the project) In Xataka | It was not an extraterrestrial ship, but not a giant kite. We were totally wrong about 3i/Atlas

There are thousands of people hooked to streaming. One to 3,900 kilometers deep full of marine curiosities (and memes)

In the Submarine Canyon of the Sea of La Plata, near Argentina, something of the most curious happens: two powerful currents coincide. One is salty and warm. The other, cold and very rich in nutrients. The union of both is the Confluence Brazil-Malvinas And it is important in the Earth’s climate regulation. It is known that there is a huge ecosystem down there, one of which little is known and that, at the moment, it is being explored live by an underwater rov next to thousands of people who, since July 23, They follow their live emissions Through YouTube. The mission. These submarine cannons hide a varied species ecosystem in their recesses. In 2012 and 2013, the Continental I, II and III of CONICET expeditions (National Council for Scientific and Technical Research of Argentina) used fishing and drag networks to explore the bed, discovering new species and leading to the publication of more than 60 Papers. Now, in 2025, technology has improved and It is possible to explore depths up to 3,900 meters with a vehicle operated remotely. Continental slope IV: Underwater Oases of Mar del Plata Canyon. That is the name of this new mission, an expedition of CONICET in collaboration with the Schmidt Ocean Institute. As explained from the Council, “it is the first time that in the Argentine Aguas of the Southwestern Atlantic the remotely operated vehicle (Rov) is used, capable of capturing underwater images in ultra high definition and collecting samples without altering the environment.” The funny thing is that the adventures of this rov They are broadcast live through YouTube. The goal. In addition to studying the Argentine seabed as it has not been possible to generate 3D models of emblematic species to produce educational material. The one who has interest can access the data collected completely free through open repositories such as CONICET Digital, Bish and Genbank. Image | CONICET How is the thing going? According to Explain The CONICET researcher in the MACN and scientific chief of the expedition, Daniel Lauretta, “we are barely starting and we see incredible things: animals that had never registered in this area, underwater landscapes that seem from another planet, and behaviors that surprise even the most experienced scientists.” It also states that being able to broadcast it live makes “science is somewhat distant or inaccessible, and becomes part of the day to day. In addition, it forces us to explain what we do clearly, without turns, so that anyone can understand and enjoy it.” The memes. That streaming has become so popular, has undoubtedly helped the collective ingenuity when seeing comedy in the seabed. It is an unknown territory for most and the species that live there are striking. That is why it is not surprising that networks like X have been filled with captures, memes and funny texts with these species as protagonists. The capture of that sea star has gone around the world, but it is not the only one. As for whatever, users have baptized it as “Estrella Culona” | Image: Xataka Argentina Caught in fraganti | Image: Xataka Argentina A violet benthodytes. His nickname: Batatita | Image: Xataka Argentina “Me and the boys together to see a stream of the CONICET,” says an X user | Image: @Genaro23101 Jokes apart, why there? The Malvinas current moves north from Antarctica to almost Río de la Plata, dragging cold and nutrient rich from Antarctica to the Patagonian platform. This current is very important for Argentina and its fishing industry, valued at 2,000 million dollars According to Schmidt Ocean Institute. The current of Brazil, more superficial (700 meters or less), transports warm and salted water from Ecuador to Rio de la Plata. Where both currents collide a strong thermoclin that, in turn, and due to temperature differences, generates rotating currents that redistribute heat, helping to regulate the climate of the earth. As explained by the institute, “the mixture of these two mass of water so different probably creates conditions that facilitate the coexistence of temperate and tropical organisms, as well as species that can only be found in the confluence.” Hence this area has so much scientific interest.
