We have a problem with plastic recycling. Japanese scientists have created one who self -destructs in the sea

by

In summer, more than once we have been scared thinking that a plastic was, in reality, a jellyfish. Far from that triviality, a major problem is hidden. According to the United Nations Environment Program (UNEP)more than eleven million metric tons of plastics end up in the oceans every year. Although a new wave of change is brewing in Japan with plastics that get rid of. Short. A group of researchers from the Riken Center for the science of emerging matter and the University of Tokyo has developed a plastic capable of degrading completely in salt water in a matter of hours, As explained in a press release. The demonstration. The team has shown how a small piece of the new material disappeared in a container with marine water after being agitated for about an hour. Although no marketing plan has yet been detailed, the project leader, Takuzo Aida, He has affirmed Reuters That research has aroused great interest, even from the packaging sector. A deep problem. The urgency of this advance is framed in an increasingly serious environmental crisis. According to UNEPplastic pollution could be tripled by 2040, reaching up to 37 million metric tons annual in the oceans. Therefore, the investigation has not wanted to limit itself in the visible, but also in the microplastics that are infiltrated in all the ecosystems of the planet. Long journey. According to They have explained Scientists, this new material is the result of more than thirty years of research in supramolecular polymers. Unlike traditional plastics, which remain united by very resistant covalent bonds, they use weakest and most reversible links. This allows the material to maintain its resistance, but decompose rapidly under the appropriate conditions. The point. To achieve this, they needed a “passage key” that was in salt. Technically, They have detailed Reuters that the combination of hexametafostato sodium (a food additive) and ions of Guanidinio (employees in fertilizers) formed saline bridges that provided stability to the material. However, by immersing themselves in salt water, these bridges are broken and, within a few hours, there is no trace of the plastic. The resulting material is resistant, colorless, igniphed and not toxic. It can even waterproof with a hydrophobic coating, without losing your ability to break down if your surface is scratched or drilled. Although it has its limitations. As The project manager has indicated to Reuterswhen decomposing, plastic releases nitrogen and phosphorus, elements that can be reused by microorganisms or plants. However, if they accumulate in a uncontrolled way, they could alter coastal ecosystems, favoring phenomena such as algae flowers. To avoid this, the researchers propose a controlled recycling system in seawater treatment plants, which would allow to recover the materials and reuse them in new supramolecular plastics. Biodegradable, but enough? The novelty of Japanese plastic contrasts with the limitations of other called biodegradable plastics. According to the researchersmaterials such as polylactic acid (PL), although they degrade on land under industrial conditions, persist in the ocean, where they fail to break down and end up forming microplastics. Other more recent alternatives, such as certain recyclable plastics developed in Europe, offer greater durability and recyclabilitybut they still face similar challenges: slow degradation in the marine environment and dependence on specific management systems. One step further. That moment could be closer than it seems. Meanwhile, jellyfish will continue to be jellyfish. But at least, the plastic that imitates them could begin to disappear.

North Korea was going to throw his greatest war boat and ended up sinking it into the sea. Everything points to a culprit: Kim Jong-un

by

Making a fool of it is something that It is not anyone’s pleasure. Surely you have ever stumbled down the street and looked around to see if someone had seen you. Now, imagine that what stumbles is a Military ship of 5,000 tons and several million dollars and sinks at the time of its premiere. That is what happened last week when Kim Jong-un He witnessed how His brand new war ship sank before the impotence of all those present and under the watchful eye of the rest of the planet. And everything indicates that the error was because, as the Spanish proverb points, the hurry are not good. Short. Days before the event, satellite images They showed both the vessel and a scenario in which what seemed to be an observation zone. Probably, the place from which Kim Jong-un was going to witness that historic moment. And the truth is that it was historic, but not for the reasons he would have wanted. On May 23, during the launch ceremony of the new North Korean destroyer (the second of its most advanced class), all attendees in the front row and the world was witnesses of a Technical failure that ended in disaster: the ship overturned. That symbol of power, with 143 meters in length and 74 vertical missile launch cells, ended up ridiculous. How do we float it? Satellite images later Analyzed by the Center for Strategic and International Studies, or CSIS, they showed the ship partially sunken with tarps that covered the disaster. And, although at first the rush was blamed, we now have more clues about everything that could go wrong. Obviously, there is no official information from North Korea, but in The New York Timeswe can see that there are analysts who are quite clear what the problem was. Or the sum of them. Image | CSIS/BEYOND PARALLEL/MAXAR When a ship is finished, there is Several ways to ‘throw it’ into the water. We have the sliding launch in which the ship slides on a ramp into the water. The dry dock in which the ship is built in a dry dock and, once finished, the water dike is filled (That is done with cruises). Also the mechanical launch by cranes, the launch with airbags that are placed under the ship and allow it to slide to the water. And the side launch that drops the side ship into the water. Normally, a single technique is used, but in the North Korean destroyer disaster it seems that sliding and side techniques were used. And not because that’s how it was planned. Perfect storm. As noted The New York TimesIt was the first time that analysts watched North Korea use the side launch to throw a war ship. This technique is sure if it is done well, but in Large ships It is more likely that a problem appears, with dire consequences if it happens. The reading of the analysts is that, using that technique for a 5,000-ton ship points to a lack of experience added to the political pressures by Kim Jong-un to achieve rapid results. The destroyer was manufactured in the port city of Chongjin that has experience assembling ships of such magnitude, but not something as huge as this ship. This puts on the table that a possible trigger was that inexperience When throwing such large ships. In the absence of a dry dike of the appropriate size, it is estimated that the engineers tried the lateral launch to throw it into the water, but the angle was not correct and, when trying to slide it, the ship was unbalanced and ended up lying on the right side. When it goes well, as happened with this fighting ship of 3,500 tons in 2013, it is worth seeing: And it can also go wrong: The hurry are not good. Interestingly, this destroyer is from Choe Hyun classwhose first model was inaugurated successfully Last month. It was going to be the second great frigate of North Korea and the new example of that naval remodeling that Kim Jong-un is promoting. And the precedents were good: the first It was built In the city of Nampo and, because it is a larger shipyard, they could put it afloat through the technique of dry dock. There were no major problems and, at the inauguration, the ruler saw how test missiles were thrown successfully. However, there are hurry in the government dome to follow demonstrating to the world its military potentialwhich has led the president to visit the shipyards who are building new ships to accelerate delivery deadlines. In addition, there are information They point out that, although the ship could have thrown out correctly, the ocean exit street is narrow and has a questionable depth. I made a. pic.twitter.com/urflog6leo – Dr. Jeffrey Lewis (@armsControlwonk) May 22, 2025 Firm hand. And who will pay for this? At the moment, the ridiculous has resulted in several arrests of members of the responsible shipyard itself. The Central News Agency of Korea reported that the chief engineer, a senior armament official and another member of the installation had been arrested, and Kim himself described The accident as a “criminal act”, demanding An urgent restoration of the ship before June. Country engineers estimate that, pumping seawater, they can straighten the ship and repair damage. And it will take about ten days to do it, but it seems complicated because, after a week, Keep as it was. Sentinel-2 images of May 23 and 28. Despite the clouds, we can see that the destroyer continues exactly at the same point And sarcasm. From South Korea, which always have an eye and a half placed in what their neighbors doThey think something else. Yang UK is an expert in North Korean military affairs of the Asan Institute for Policy Studies in Seoul and, as Tnyt comments, the incident may not be only an accident, but something caused by a structural imbalance on the ship itself. … Read more

take the sea to its interior cities

by

China has been paid for a long time Megaconstructions. Some of the most important projects in recent years have had China as the main country. Your approach differs from the Torres Carrera that we see between Saudi Arabia and Arab Emirates: Chinese works are looking to unite the territory with huge bridges either impossible tunnels. Within that ambition are channels such as Pinglu that They look take the sea to the interior cities. And everything is part of China’s strategy to master the world market. Pinglu channel. After years of planning, in 2023 the works of this channel located in the Guangxi region began that will connect the Yu interior river with the Gulf of Tonkin, located in the controversial and transcendental sea of ​​southern China. It will be key to the transport of goods, since the channel will save 560 kilometers away that must be traveled by roads. The channel is expected to be able to start moving merchandise in December of 2026 and the cost of the project points to be about 9.3 billion euros. And all the figures surrounding the project are rimbombantes. Colossal. Pinglu’s is the First big channel built in China from the Foundation of the Popular Republic and talk about channels such as Panamaa vital point for worldwide tradeeither The future Sena-NorteIt implies talking about elements that are authentic wonders of hydraulic engineering, as well as capital importance in globalization. He Pinglu channel It will be ambitious in the length that will cover, 134 kilometers, but also for its role in China’s strategy. Ships with up to 5,000 tons of dead weight and dimensions of 90 meters of length, 15.8 manga and five draft are expected. Your system will be based in two locks 300 meters long and 34 wide that will allow to exceed unevenness up to 65 meters. Beyond saving the unevenness, these locks are being built so that they operate quickly, opening and closing in a short time to expedite the paths. Mass work in record time. Of those 134 kilometers long, just 6.5 kilometers are new, but for the rest they have had to adapt the rivers to accommodate the ships. To do this, more than 50 million cubic meters of material have been moved and the total excavation is expected to be more than 339 million cubic meters. This is more than three times the volume of the Monumental dam of the three throats. Beyond the technology that the locks are being equipped, a concrete mixture designed for Resist marine water erosion For more than 100 years, minimizing maintenance. And if it begins to operate in 2026, as planned, there will barely seven years since the firm approach of the work began and three since it began to be built. Controversies. Moving that amount of land and doing it in certain areas close to the rivers has a problem: the ecosystem of some species may be endangered. Environmental concerns revolve around this, since the works are carried out very close to mangroves, which could be seen affected for the works. Strategic trade. However, 5,000 -ton ships are considerably smaller than others that cross the Panama Canal and that of Suez (which can exceed 65,000 tons), but the idea is that these ships arrive from the interior areas to the marine ports and, from there, follow their destination as part of the great dream of Xi Jinping: the New Silk Route. Because the Pinglu channel is closely linked to this new commercial corridor and connect the western interior and southwest China with international markets is a very important part of this strategy of the country to strengthen and diversify the export and import routes of the country to the rest of Asia, Africa and above all, Europe. Hopes. Apart from that improvement in the commercial connection, China expects the pinglu channel Reduce transport costs. A ship is considerably cheaper than other media such as trucks, trains and airplanes, so they expect saving of about 725 million dollars annually. In addition, it will contribute to decongesting traffic in the region, a problem that the country suffers in its most industrial areas. In addition, although the project is mainly for transport, wait to bring improvements in water management for irrigation, but also serve as a measure of avoiding floods in the area. Beyond pinglu. As dizziness that are their figures and the short deadlines that they handle to lift pharaonic works, Pinglu’s is just one more piece in the China Geopolitical and Commercial Board. Because the country has plans for other international corridors, such as Kra in Thailand to avoid the Malaca Strait, which is another key point of the new silk route, but also more modest interior channels. For example, that of Zhejiang-Jiangxi-Guangdong, that of Jinghan or Xianggui to unite on these river highways interior regions and promote trade, as well as industries such as steel while reduce contamination of conventional road transport. And it is all of an ambitious strategy of China for promoting trade inside and outside its region and, therefore, with the objective of increase its importance in the market and global policy.

Germany is installing giant concrete spheres under the sea. You have a good reason: store renewable energy

by

While France and Germany reinforce their energy alliances with a renewed bet For nuclear energy, within the German country they are developing a completely different system. The focus is on marine depths, with the aim of redefining the way in which renewable energy is stored. Under the sea. A group of researchers the Fraunhofer Institute of Germany They have created the Stensea project (Stored Energy AT Sea acronym). Since 2011, the equipment has worked in a solution to reduce land use, reaching the conclusion of sinking huge concrete spheres into the seabed to store energy. The operation. These spheres sink at 600 and 800 meters deep, where water pressure is so high that it can rotate turbines with great efficiency. Each one measures about 9 meters in diameter and weighs about 400 tons. The idea is that they work as giant batteries: by letting the sea water in, it moves a turbine connected to a generator. To recharge it, water pumps out, using network energy to overcome environmental pressure. A design of what a Stesea plant would be A real test. The system has already been successful at Lake Constanza, and now the next step is marked in the calendar by 2026. It is expected to install a prototype real and 3D printed on the coast of Long Beach, in California. This model can generate about 0.5 megawatts and store up to 0.4 megawatts-Hora, which would be enough to cover the consumption of a middle home in the United States for about two weeks. The future idea is ambitious: building much larger spheres, up to 30 meters in diameter, capable of storing much larger amounts of energy. The objective is to climb the system with spheres up to 30 meters in diameter, which would allow a much larger storage capacity. According to They have detailed Newatlas researchers, the estimated storage cost around the 5 cents per kilowatt-hora, a very competitive figure compared to other current solutions. Renewables in Germany. Although it seems contradictory for its climate, the country has been strongly betting on solar energy, especially In self -consumption facilities. However, it faces an important challenge: intermittent production, or Dunkelflaute. For this reason, projects such as Stesea can act as a shock absorber of the electrical system, because it stores excess renewable energy and releases it when it is most needed. So hydroelectric plants? Unlike traditional pumping storage –which requires mountains and large fresh water reserves-, this system does not need limited elevations or water resources. Its modular design allows it to install it on coasts around the world. In addition, this system has raised An economic advantage since it allows energy arbitration, buying electricity when it is cheap and selling it in moments of high demand. Forecasts The researchers They believe that this technology He has barely shown the tip of the iceberg. They estimate that, if it was deployed on a large scale, it could reach a global storage capacity of about 817,000 gigawatts-Hora. Translated to something more tangible, it would be enough to supply about 75 million homes in Europe for a whole year. However, although the project is presented as a solution to avoid intensive soil use, it does not stop moving that occupation to the seabed. Until now, the approach has been mainly technical, but it would be expected that in future phases rigorous environmental evaluations will be included that analyze its impact on oceanic ecosystems.

China is immersed in a nuclear revolution and needs industrial amounts of Uranium. His solution: “fish” in the sea

by

China is one of the countries that is most promoting the adoption of renewable energy thanks to Great ‘farms’ and market saturation of solar panels. At the same time, they have approved the Construction of ten new nuclear reactors. It may seem a contradiction, but in the midst of a Strong commercial warit is another step in energy self -sufficiency, and to achieve it they will need tons of uranium. Your solution? Squeeze the uranium of the seas. Marine mine. The country account with 56 nuclear reactors and has between 25 and 29 under construction. This implies that they need a lot of Uranium and the problem is that they do not produce enough. HE esteem That, in 2023, China’s production was only 1,700 tons, 4% worldwide, and although they have strong reserves, they need more. In turn, China imported Some 22,000 tons in 2024 and have begun to put solutions. In 2024 began The construction of the National Project of Uranium Nº1 in Ordos. It will become the largest uranium mine in the country and a few months ago They announced that had discovered another important site, also in Ordos. However, it still is not enough, so they have seen the sea. Uranium fish. Because yes: there is uranium in the oceans. Its concentration is extremely low, about 3 micrograms per liter, but due to oceanic immensity, it is estimated that the total is 4.5 billion tons of uranium. There are a thousand times more uranium in the seas than in known land reserves. Extract Uranium from the sea is not something new and, during the 80s, Japan led the development of marine uranium extraction techniques. The problem is that it is a complex and, above all, inefficient process. That is why researchers focus on active uranium collection methods‘dapando’ different materials to be able to extract more material per liter. It is also a expensive method, about ten times more to extract it from terrestrial sources. Miraculous material. But this is where the Chinese team of the Frontiers Science Center For Rare isotopes of the University of Lanzhou enters. In a study published in NatureThey explain that the key to extracting more efficient marine uranium resides in the MOF, or metal-organic frameworks. It is a crystalline material composed of metal ions that are coordinated with organic elements to form structures of great porosity. It is like an extremely efficient fishing network to catch small particles that, in the case of uranium, allows you to better separate this element from others to which it can be attached. The Chinese team has dopa with Dipniletinelo molecules and claim that this new DAE-MOF material allows an uranium absorption capacity of 588 mg per gram, according to the tests. This involves an efficiency 40 times higher when separating uranium from metals and vanadium and has been tested both in simulated and real sea water. Aim. The idea is now to create test extraction plants this year, with pilot plants on the tons scale for 2035 and with a continuous production by 2050. wait That China’s demand for uranium is more than 40,000 tons in 2040, so land mines in conjunction with these marine alternative sources are essential to achieve the goal. Without a doubt, it is an advance in marine uranium extraction at a time when the rest of the players on this board are also found Looking for ways to get more out of the sea for energy independence at a time when buying to other countries He has put up legs. And the United States, of course, is also in that fight, with the US Department of Energy analyzing The technical, economic and environmental viability of large -scale uranium extraction in its waters.

Starship flight 9 includes such a risky maneuver that will be tested at sea, not to destroy the tower

by

After Two consecutive flights in which the Starship ship exploded shortly from separating from the propeller, a conservative approach could be expected by Spacex for the ninth launch. Nothing is further from reality. Double Tirabuzón without a network for the Super Heavy. Elon Musk’s company knows how to maintain emotion for flight 9, and the riskiest plans focus on The largest part of the rocket: The Super Heavy propeller. Spacex will not only reuse for the first time one of the three super heavy who have successfully landed in the arms of the launch tower. At the same time, plan to test With only two available engines For braking and landing maneuver. It is a deliberate resistance test to verify what would happen if a propellant engine fails during the reentry. Straight to the Gulf of Mexico. In this case, Spacex will not try to catch the propeller for the second time. The landing maneuver is so extreme (first super heavy used, with only two lit engines and without failure tolerance) that the rocket will discard. Instead of returning to the tower, he will make an essay of the maneuver in the Atlantic Ocean, finishing his mission with a shocking. Spacex already has a second Mechazilla tower in Starbase Able to catch rockets with his robotic armsbut he needs both for when, in addition to the 70 -meter Super Heavy propeller, the 50 -meter Starship ship begins to land in the other tower. Something that Spacex would have tried for the first time on this flight 9 if it had not been for the catastrophic failures of flights 7 and 8, which have delayed those plans. Even so, we are going to have fun. 29 used engines. Spacex has already done a proof of the propeller which will launch the Starship in this ninth launch: the Booster 14. He took off for the first time on January 16 and was successfully captured by the tower a few minutes later, while the starship lost control. The first time Spacex reused a falcon 9 propeller A year had passed Since its launch. With the Super Heavy just three months have passed. In addition, there is no trap or cardboard: 29 of the 33 engines that wears the booster 14 are used. Of course, Spacex is still far from rapid reuse type “Zero-Touch reflight“(land, load propellants and take off again) to which he aspires. Especially with the ship and its thermal shield. All eyes put on the ship. To land a used rocket of 70 meters high with a less engine is impressive, but the super heavy will not be the protagonist of this flight. It must necessarily be the Starship 35 because it is the third ship of version 2 that will launch Spacex. His two predecessors had an abrupt ending for excessive vibrations near the engineswhich led to leaks, fires and explosions. The S35 ship completed its cryogenic tests in mid -March, but has not made a long ignition like the S34, and there are doubts about how Spacex will face its launch, because the flight profile has not yet been published. Nor the results of the investigation on flight 8, nor the flight license of the Federal Aviation Administration, so it seems unlikely that Spacex takes off at the date initially scheduled (April 18). Mars does not expect. Yes, on the other hand, the investigation of flight 7 is closed, whose 11 corrective actions were implemented before flight 8. Without much success, since it failed again. Flight 9 is not expected to require a modification of the flight license, but the approval of the FAA is indispensable to schedule the launch. Spacex needs to accelerate the step to meet Elon Musk’s goal of an unmanned mission to Mars (with Robots Tesla Optimus) By the end of next year. The earth-marte transfer windows occur every two years, and Musk does not want to waste time. But Starship is already pushing the limits of technology and the last thing he needs is a third explosion about the Caribbean.

500 million years of evolution separate us from sea stars, but there is something that has not changed so much: our appetite

by

Hormones are molecules that exert the functions of messengers in our body. They take part in a large number of physiological processes, among which are the food and digestion of the food we consume. Among them, we know several hormones that regulate appetite and satiety. Evolutionary History A new study has analyzed The evolutionary history of bombsin, a hormone capable of transmitting the signal of satiety to our brain. This hormone had already been detected in some species of vertebrates and we know that it is capable of exercising this function in humans. Now we have found the genes that encode these hormones in very distant species evolutionarily, such as sea stars. Bombsin Bombsine was discovered in 1971, not in humans but in an amphibian, the belly toad fire (Bombina Bombina). It is a small peptide similar to those used by our own body to transmit (among other “messages”) the sign that we have satiated, molecules such as glucagon, the gastric inhibitor peptide (GIP), or the peptide similar to glucagon-1 (LPG-1). The researchers who studied the bombsin verified that, by injecting it into mammals, this also caused a feeling of satiety. This caused the subjects to reduce the amount of foods they consumed and space their intakes more over time. Needle in a haystack. In his study, the team responsible for New Research, began to study the genomes of different invertebrate animals until it ran into genes capable of encoding hormones similar to bombsin. And they found them in several equinoderms species (Echinodermata), As for example in the common sea star (Asterias Rubens), but also in hedgehogs and sea cucumbers. “It was like finding a needle in a haystack,” explained in a press release Maurice Elphick, co -author of the study, “but finally we discover the genes that encode a neurohormone similar to the stars of sea stars and their relatives.” Arbn.After that, the team studied the function of this hormone, which they called Arbn. Through mass spectrometry, the equipment was able to determine the molecular structure of the compound, thanks to which they could synthesize it and submit it to test. Thus they found that the hormone had an impact on the gastric processes of sea stars. “When I put Arbn, I saw that it caused contraction in the stomach of the sea star,” Weiling Huang addedCo -author of the study. “This, Sig would, that Arbn could be involved in stimulating the stomach retraction when the sea star stops eating. And that is precisely what I saw. When I injected Arbn into the sea stars (…) it made the stomach retract (…). What is more, arbn also delayed the beginning of the food, since the stars injected with arb those that water was injected. “ The details of the study were published In an article In the magazine Proceedings of the National Academy of Sciences (PNAS). Making historians. The study gives us new clues about how our digestive system and its tools to control its internal processes evolved. A track that allows us to ride ourselves 500 million years ago, when the last common ancestor of humans and sea stars inhabited the earth. But the finding also has significance for the pharmacological industry. In recent years they have seen the rise of various treatments based on hormone analogous substances such as LPG-1 or GIP. Compounds such as semaglutida (better known by its commercial name Ozempic) or the tirzepatida (Tirzepatida) were born as diabetes treatments but achieved success as losing weight formulas. These compounds emulate the hormones that our body secretes behind meals, hormones that fulfill the function of communicating to organs such as the pancreas that our digestive process is underway but that also transmit to the brain the message that we have satiated our appetite. Compounds such as Bombsine, Arbn, or similar could perhaps be used also In this context. In Xataka | Japanese researchers have studied how to eat less.

The difficult thing has not been to build a yacht of 80 meters and 200 million dollars. It has been to take it to the sea without destroying it

by

Imagine living in a quiet town near Rotterdam, and when you look at your window you see a colossus for you, 14 meters wide and with the height of a three -storey building. It is what has happened (once again) to the inhabitants of the quiet town of Alphan (Netherlands). According to published the local media AD Those who have approached one of the channels that are going through the population have seen how A 200 million superyate of dollars Lawrence Strollowner of the Aston Martin Formula 1 team 1 and head of Fernando Alonso, juggled to reach the sea sailing through narrow channels and raffling bridges and all kinds of obstacles in his odyssey. The megayate odyssey Feadship is one of the world’s main manufacturers in the world. From their shipyards in Aalsmeer they have left colossi like the Launchpad by Mark Zuckerbergwith 118 meters of length. All of them have had to go through that intricate journey of narrow channels, curves that test the expertise of the engineers involved in the transfer and several traffic cuts in the populations through which they pass. This type of operations are not simple. They require millimeter planning and the perfect execution of each step. Any calculation or maneuver error could have ended up damaging the helmet of a vessel valued at more than 200 million dollars or, worse, putting people’s safety at risk. The epic odyssey of PROJECT 714production name that the Stroll Yate has received, was recorded on video for the Dutch Yachting Channel. Some sections of the transfer were especially tense, such as the pass There were hardly a few centimeters of margin so that the superyate helmet scratches its pillars. The tight turns in the channels, as a chicane in an F1 circuit as in which their owner competes, also contributed their touch of tension during the hypnotic transfer to high seas. Project 714 Leaving the shipyards When even money can pave the way PROJECT 714 is neither the first nor the last supereyate that makes this journey, but its complexity reaches the extreme when it comes to large vessels such as the commission of the owner of the Aston Martin Formula 1 team 1, with an estimated heritage in 3.8 billion dollars, according to Forbes. The journey of Koru de Jeff Bezos From the Oceanco shipyards in Alblasserdam, it was a challenge the exit to the high seas through some channels similar to those that has had to travel the Spery of Stroll. On that occasion, the Dutch builder had to face A serious problem: A historical drawbridge built in 1927 was not high enough for the 70 -meter masts of the Koru to pass under its structure, so the construction company proposed to temporarily dismantle the bridge so that the sailboat could cross it. According to The published by the local medium Truuwthe refusal of the neighbors forced the refusal of the City Council, so the builder had no choice but make the journey without masts to complete the construction of the Koru in the shipyards that the company has in Greenport. A floating mansion Ad picked up some of the reactions of Alphan’s neighbors who came to see how Project 714 slid over the waters of their narrow channels. “This is quite impressive,” “is not normal”, “the closer, more impressive” or “we are in first class” are some of the comments that raised in its path the impressive mole of steel and aluminum. The luxurious yacht is designed to be A floating mansion destined for leisure and It has five covers, A beach club with pool in the stern, an sharp bow cover that could well host a helipad and wooden floors in all covers. When being in manufacturing phase, Feadship does not give many details about his Interior equipment and finishessomething that will be addressed after overcoming the navigation tests that it now faces.

GTD dropped the German rocket Spectrum to the sea during Sunday launch

by

Isar Aerospace declared successful the launch of your Spectrum rocket To the north of Norway, but it was a Spanish company that saved the day in some way. Context. The German company Isar Aerospace tried to launch the first private orbital rocket in Europe on Sunday. After lighting the nine engines of its first stage, the Spectrum rocket cleared the launch platform, located on the island of Andøya, north of Norway. 18 seconds later, Spectrum began to turn and correct its orientation orientation. Half a minute had passed from takeoff when the engines turned off and the rocket fell into the sea. The 28 -meter pitcher, loaded with propane and liquid oxygen, finished his inaugural flight with a great explosion. The Spanish contribution. GTD, an engineering consultant based in Barcelona, ​​was in charge of Develop the launch control system (LCS) of the Andøya Space Puerto. This system supervises the countdown and flight safety of the Spectrum Spectrum of Isar Aerospace. His role was fundamental in the rocket debut. Not only because the countdown worked perfectly, but because it successfully activated the flight termination system that made the rocket safely to the sea. Flight termination system. Unlike other rockets, Spectrum does not call themselves when something goes wrong.

2003 was the year of ‘The Lord of the Rings: The Return of the King’that of the first movie of ‘Pirates of the Caribbean’, ‘Terminator 3’ and The double of ‘Matrix’ on the billboards with the launch of ‘Reloaded’ in May and ‘Revolutions’ months later. In the middle of that Thaquillazos drizzle With millionaire collections, movie theaters welcomed another great success of success much more discreet (although success after all): ‘Master and Commander’the tape of Peter Weir in which a russel crowe freshly raised by ‘Gladiator’ Encarna Captain Jack Aubrey. His box office box touched the 212 million of dollars, enough to cover the budget (150) and leave a good mattress, but not to encourage producers to bet on a second part or (Still, at least) a prequel. With the time ‘Master and Commander’, however, something much more complicated has achieved: becoming a classic with a good community of followers (many of them men) fascinated by their plot and character. And it makes all the meaning. When time helps. There are films that the passage of time feels like a bathroom with bleach. It dazzles and corrode. And then there are others that win the varnish of the classics. ‘Master and Commander’ is one of the last. Not for a simple matter of subjective criteria. No. It comes quickly for Google, X or Reddit To verify that almost 22 years after its premiere (they will be fulfilled in November) it continues to generate conversation, with a large legion of fans who continue to review the film to get new readings. Click on the image to go to Tweet. It’s cinema … and it’s philosophy. It is not just that his level of approval in Rotten Tomatoes for example exceed 80% or occasionally News arise On the plans to roll a prequel. Throughout the last years Peter Weir’s film has starred in broad analysis in media such as GQ, The conversation, The Guardian, Den of Geek either Literally Hub (the latter with a February piece) that go beyond the technical aspects, the actions or the plot of the film to focus on its background, especially in its representation of masculinity, friendship and leadership. The key was given by Gabriella Paiella in A broad article Posted in 2023 in GQ With the title “Why are there so many boys obsessed with ‘Master and Commander’?” The answer was recently given in X (confirming his premise) David French, columnist of New York Times: “Because it is perfect and amazing and everyone should see it 100 times.” French is not alone in that opinion. Even today, 22 years after the premiere of the film in theaters, they are Recent references and comments praiseful In X. Why’s that? For several reasons. The main one is probably the readings and messages that advance in parallel to the plot. Recall: ‘Master and Commander’ is an epic movie that adapts the novels of Patric O’Brian And he tells us how, with the Napoleonic wars as a backdrop, the British frigate HMS Surprise looks for the French ship Acheron in the Pacific Ocean. Crowe embodies Jack Aubrey, captain of the frigate of the British Royal Navy. The other key character is his friend, the naturalist and doctor Sthepen Maturin, played by Pablo Bettany. But above all the real attraction of the film, beyond its action or landscape scenes, is the environment that recreates and the relationships between its protagonists. Moreover, there is who says That at times the tape becomes “a pure study of characters”, in which the persecution of the Acheron ship is in the background in favor of what is really important: friendship between Aubrey and Maturin. A ship movie … and friendship. In 2023 Matilda Hatcher, of the Australian National University (ANU) summarized it clearly in An essay About the movie. What attracts so many spectators more than 20 years later is the link of Aubrey and Maturin and the representation of masculinity. “They are not necessarily nautical adventures that attract men, but healthy and affectionate male relationships,” Comment. That message connects With people who saw the movie in his day, being a teenager, and now he faces a new vital stage, advanced thirty or fulfilled 40, in which the film brings him new valuesand readings. “The interpretation that Crowe and Bettany make of the friendship between two men is up to this art (…). Much of the lasting attractiveness of the film lies in that representation of the male closeness,” agrees Martin Pengely in The Guardian. “In my opinion, a middle -aged man whose most intimate friends live more than 5,000 km, ‘Master and Commander’ presents an inspiring vision of vital relations for health and happiness.” A concept: “positive masculinity”. That is probably the other great key to the popularity of ‘Master and Commande’, a film in which otherwise there are no more relevant female characters, with the perhaps exception of the bow mask and a female face seen fleetingly against the coasts of America. In a tape of this type, life in Altamar, sailor rough and with a classic male hero, the representation of masculinity stands out. “At 20 years, Weir’s work remains a captivating historical drama and an emblem of healthy masculinity,” Defend Hatcher. At the time of Handsfsera And between messages that advocate hard masculinity and the “shark mentality”, ‘Master and Commander’ transmits a different message: it clings to positive masculinity, the classic archetype marked by duty, sacrifice, the search for justice and especially companionship, without egolatries or arrivals. A comfortable, soft, universal reading that goes beyond generations and is defined by values ​​that are not conflicting. Or like summarize it Paiella: “A sign of positive masculinity.” In Xataka | It is not your thing, your friends are probably more popular than you: it is the paradox of friendship
