an underwater cable through the North Pole

by

He 99% of international internet data traffic travels through fiber optic cables that run along the bottom of seas and oceans. There is a kind of Google Maps of underwater cables where you can see its trajectory to discover that, while there are areas that are true wastelands, in others there are tangles of cables that clump together. Precisely these areas are critical for potential accidents and attacks. Well, 90% of the capacity of the Europe-Asia cables happens through a region that is anything but calm: the Red Sea. In times of peace these cables work well, but in conflicts they are a real candy for sabotage: they are “abandoned” to their fate in the middle of nowhere, they are strategic and repairing them is not exactly easy or convenient. And in fact, in the case of these Europe – Asia cables it has already happened: in 2024 a Houthi missile impact a cargo ship in the Strait of Bab-el-Mandeb and its drifting anchor cut three underwater cables. Repair ships were able to enter four months later. In September 2025, history repeated itself. The Achilles heel is clear and Europe wants to solve it by detouring around the North Pole. The alternative route: Polar Connect. The European Union, through its resilience panel, has recommended building two Arctic cables to reach Asia by avoiding the Red Sea: one would go through the Canadian Northwest Passage and the other would connect Scandinavia with Asia by directly crossing the North Pole. The latter is precisely the Polar Connect. Said and done: the EU you have already labeled this cable as “Cable Project of European Interest” and has already prepared the first funds for its construction. The total estimated cost is around €2 billion and the operational goal is 2030. Behind the project is the Nordic research and education network NORDUnetNordic network operators such as GlobalConnect Carrier and the Swedish polar research agency. This summer probably they will do a study of the route. Why is it important. Because submarine cables are the roads that keep the world in which we live connected: corporate communications, cloud services, finance, streaming, security… and the fact that the majority of connections between Europe and Asia occur through a corridor in persistent conflict increases the risk of blackouts between both continents. This cable seeks to minimize geopolitical risk while reducing latency in data transmission. On the other hand, there is its strategic dimension: Meta, Google, Microsoft and Amazon now represent more than 70% of all submarine cable capacity consumed globally, compared to less than 10% a decade ago, according to TeleGeography data and GlobalData. Europe does not have any route of its own to Asia. How Polar Connect collects in your white paperthe three current options between Europe and Asia are the Red Sea, Russia or passing through the United States and none are under European sovereignty. The two new cables to connect Europe and Asia via the Arctic route. NORDUnet Context. The Red Sea and its surroundings have been an almost continuous hornet’s nest since at least the 1950s: the Suez crisis, the Six Day War, Yom Kippur… so as Roderick Beck, a cable industry veteran who is dedicated to finding telecommunications capacity for internet service providers, explains for The Verge: The industry looked for alternatives in the Persian Gulf, but it is not exactly an oil raft either: The United States attacks on Iran in 2025 also closed that route. That said, the geopolitical context in the Arctic is not neutral either. Historically to run a cable through the arctic was necessary a partnership with Russia, but since the war with Ukraine, the North Pole corridor lacks of western intercontinental connectivity. However, it will not be easy: others have tried it before and failed, such as Quintillion on the north coast of Alaska. They activated a section of cable, but the ice broke it twice and to repair it it is necessary either to have an icebreaking ship to repair the cable or to wait until summer. How do they want to do it?. He plan is connecting the Nordic region with Japan and South Korea via fiber optics under the Arctic Ocean with possible branches to North America. Regarding financing, at the end of 2024 were approved 44.6 million euros from the Connecting Europe Facility program for the first phases. Polar Connect will also have with advanced sensors for environmental and climate monitoring, so that it would function as a telecommunications infrastructure and an Arctic scientific research instrument. The project is complemented by Far North Fiber, another Arctic cable that would take the Canadian Northwest Passage route. Together they would form a network with mutual redundancy: when one fails, the other takes over the traffic. As it says the CEO of NORDUnet himselfValter Nordh: “both routes have strengths and weaknesses, which is why they complement each other well.” Yes, but. Designing, building and installing an underwater cable is not a small project, but the main problem that Polar Connect is going to face has already been glimpsed in the failed Quintillion project: the obstacle is maintenance. The ice cuts and the icebergs drag the seabed to depths greater than those that allow the cable to be buried in a phenomenon known as ice scour. If there is a break in winter, we have to wait until summer to repair it simply because there are no ships capable of breaking ice and laying cables at the same time. Alan Mauldin, research director at TeleGeography, one of the leading research companies in the sector, he says it bluntly: “We’ve seen a lot of (Arctic cable) projects happen. There’s a reason for that, right? It’s very complicated.” In Xataka | The submarine cables belonged to the teleoperators, and now the big technology companies are controlling them In Xataka | The first great Atlantic submarine cable that connected us to the internet says goodbye for a simple reason: it was too expensive to repair it Cover | PxHere … Read more

This is how a supermassive black hole wakes up

by

A team of scientists led by Riccardo Middei, from the INAF Astronomical Observatory in Rome, has monitored the step by step of a black hole “resurrecting” after “taking a break.” After monitoring for six years the galaxy that houses ithave been able to see how, after a clear decrease in its brightness, its activity increased significantly. This has allowed them confirm that some standards of physics were very well calculated. However, it has also been detected that some may not have been entirely correct. It’s actually more than six years.. All part of the observations of the Seyfert galaxy ESO 511-G030 that were made in 2007 and 2019 during the mission XMM Newton. It was found that the brightness of the center of the galaxy was 10 times weaker in 2019, whether measured in ultraviolet or when X-rays were detected. A previous detection indicated an increase in 2012, but since there were no measurements between 2012 and 2019, it was not possible to know exactly what happened in that period. The authors of the study that has just been published They wanted to have continuous monitoring, so they took regular data with the Neil Gehrels Swift Observatory from 2019 to 2025. Thus, they saw that, indeed, in 2019 the black hole at the center of the galaxy had practically fallen asleep. However, in 2021 a recovery began to be detected, first in the brightness measured in ultraviolet and then in X-rays. The black hole was waking up. An active galactic nucleus. The Seyfert galaxy is a galactically active nucleus. That is, it emits a brightness higher than that which would correspond to the sum of all its stars. This is because at its center there is an active supermassive black hole. This attracts all matter that gets too close to it. In fact, from a boundary known as the event horizon, not even light can escape. Throughout this process of falling into the black hole, a lot of radiation is emitted. Knowing this, we can see two parts in the black hole. On the one hand, the accretion disk, a rotating ring of hot gas and matter falling into the black hole. During its rotation, it emits optical light and ultraviolet radiation. On the other hand, on this disk is the corona, composed of hot plasma, whose emissions are mainly X-rays. This is the reason why, to measure the activity of a black hole, data are taken in both ultraviolet and Step by step. The reactivation of the black hole occurred in two parts. First of all, the brightness in the ultraviolet clearly increased, between 2021 and 2023. Then, between 2022 and 2023 it was the turn of the X-rays. Therefore, it can be said that first the activity increased in the accretion disk and then in the corona of the black hole. size doesn’t matter. By eliminating the contribution corresponding to the stars of the galaxy, the brightness corresponding to the black hole increased by 20 to 30 times. It was a radical increase in activity, which came at just the right time. And scientists calculate that the transition occurred at just under 1% of its Eddington rate. This is a theoretical figure that describes the universal threshold at which a black hole can accrete or attract matter before radiation pressure expels the incoming gas. For it to truly be a universal figure, as predicted, it would have to be equivalent for both very large black holes and stellar ones. In the stars it has already been measured. Now, in this one, which has a mass equal to 17 million times that of the Sun, the figure is practically the same, so it can be considered universal. What doesn’t add up. The limit from which the black hole “falls asleep and wakes up” seems to coincide with the theory, but there is something that does not fit so much: the speed at which it does so. Both the fade and the recovery occurred too quickly than estimated in the standard models. Therefore, it is clear that the models still have a lot to perfect. To be able to do this, it will be necessary to study more galaxies like this one. Comes into play Vera Rubin Observatoryin which so many astronomers are placing their hopes. Thus, based on observations, the missing piece may be found. Image | POT In Xataka | We already know in which region of the solar system Planet 9 must be (if it really exists)

The Silver Route seemed like the perfect train for the Spanish west. They seek to recover it with one objective: forget about Madrid

by

Cáceres and Salamanca are separated by just 200 kilometers but the journey takes seven hours in the best of cases and requires passing through Madrid. We talked, of course, about going by train. And the capitals of these two provinces represent one of the biggest railway holes that our country has. The situation is not unique in Spain (from Murcia to Granada you also have to go through Madrid) but perhaps it is more bloody because one day there was that option that structured the west of Spain. It was known as the Silver Route. Now, more than 40 years after its closure, there are those who continue fighting for its reopening. A line that was born sentenced From Seville to Gijón, passing through Mérida, Cáceres, Salamanca, León or Oviedo. The Silver Route It was designed as a railway corridor for passengers and goods away from the large Spanish economic centers. It was about finding an alternative so that not everything went through Madrid, Bilbao or Barcelona. And, curiously, its origin must be sought very far from these cities. It was in Paris in 1877 when the contract was signed to build a railway between Palazuelo (current Monfragüe station) and Astorga, they explain in The Extremadura Newspaper. The project was ambitious as it passed through a lot of unpopulated area in its attempt to connect the north of Extremadura with Salamanca, Zamora and León. Yet, the line went ahead in the last years of the 19th century. Between 1893 and 1896, the four sections that would end up forming the most representative axis of the line were inaugurated from south to north. This was the backbone of a road that connected to the south with the Mérida-Seville section and the Venta de Baños-Gijón in the north. Without a large city to drive it and without direct access to a large port, the line was falling into ostracism. First, because the State did not find sufficient reasons to modernize it and, at least, electrify it. And without investments, the tortuous path became less attractive for passengers and companies. The axis survived the Civil War but beforehand an investment had been requested that never arrived. In 1933, the iron bridges were replaced by steel ones but no major efforts were made. In the following years, they point out in the local mediaderailments and accidents multiplied due to lack of investment. For decades, once sentenced, the line remained open but in 1984 its definitive closure was confirmed. By then, the trains were barely running at 50 km/h, an average speed lower than that recorded during their opening. A train bus accident in 1981 in which a woman died put the finishing touches on a decision that began decades ago when no one wanted to invest in the western axis. Let it come back! Today, the connection between Cáceres and Seville, passing through Mérida, continues to exist, although it is a single-lane railway and is not electrified. The connection between Salamanca and Gijón is also maintained. But how you can see on this Adif mapa hole separates Cáceres and Salamanca. From Plasencia, you will see a green line leaving towards the north. In Salamanca, another leaves in a southerly direction. Are they projects to recover this train? No, they are Greenwaysconditioning of the old railway section to convert them into easy paths for walking, running or cycling. What some institutions have been demanding for years is that these Greenways are not the only vestige that remains from those days. In 2023, the city councils of Salamanca, Cáceres, Béjar, Plasencia Guijuelo and Hervás together with the Chambers of Commerce of those first three cities signed an institutional declaration demanding the return of the train. “Employment, creation of opportunities, logistical development, diversification of the productive system and stopping depopulation,” with these words they began a text to justify their demands. It pointed out some technical issues such as that the section between Plasencia and Salamanca has 4G network coverage on 90% of the route. But, above all, it was remembered that the new train could be an alternative route for the transport of goods in the western area, capable of connecting the Atlantic ports in the north with those in the south without passing through Madrid. This was the premise, in fact, with which the idea of ​​resurrecting the West Corridorunder the Government of José Luis Rodríguez Zapatero. A project that, as they remember in the text, was not carried out. in the diary Today They collected information that the Gijón Chamber of Commerce put on the table in 2022 to defend this line: it could capture up to 625,000 journeys for goods which now carry trucks going up the A-66, also known as Vía de la Plata. Beyond unfulfilled promises (in addition to Zapatero, José María Aznar also promised to reopen the line after Felipe González closed it to passengers in 1984 and to goods well into the 90s), one of the biggest problems that this Western Corridor has is that it does not fall within the plans of the European Union as far as the railway is concerned. The Trans-European Transport Network ignores this and maintains that hole already mentioned between Cáceres and Salamanca and Salamanca and the south of Asturias if it is not passing through Valladolid. Regardless of whether we are talking about a passenger or freight network, the result is the same. That is why from the Corredor Oeste platform, together with the city councils and the rest of the local organizations, They have been organizing mobilizations and meetings to press and get the project taken to Europe. According to his calculations, it would hardly be necessary to invest 1.9 billion eurosvery far from what is being invested in other corridors such as the Mediterranean, which already exceed 8,000 million in investment. They also defend that the new Silver Route railway would be key to connecting the Atlantic Corridor, which does have European approval, with the Spanish south, offering a … Read more

release 64 million mosquitoes

by

Eliminating disease-carrying mosquitoes is not an easy mission nor can it be carried out improvisedly. And if not, tell Verily, the subsidiary of Alphabet (Google’s parent company), which has been trying since 2017 with his DebugProject. How are they doing it? With artificial intelligence, robots and, as incredible as it may sound, with many, many mosquitoes. Verily’s latest move has been formally request to the United States Environmental Protection Agency permission to release up to 64 million mosquitoes over the next two years in the states of California and Florida. 64 million mosquitoes in your area. Verily has asked the EPA for authorization to release up to 32 million male mosquitoes of the species Culex quinquefasciatus bacteria carriers Wolbachia pipientis for two years in Florida and California respectively at a rate of 16 million the first year and another 16 million the next. At the time of this writing the public comment period was about to close (June 5). From that moment, the EPA makes the decision whether to approve it or not or whether to put conditions on the test. The objective of this mosquito bombardment that works as a biological pesticide is to obtain the necessary field data to, with EPA permission, market this pest control solution. Why is it important. The Culex quinquefasciatus mosquito is an old and feared acquaintance: it is the species responsible for transmitting the parasites of the avian malariaviruses West Nileof the rift valley fever and of the St. Louis encephalitis. West Nile virus is the leading cause of mosquito-borne illness in the continental United States, causing an average of 2,000 cases of illness per year and about 120 deaths. according to the US Centers for Disease Control and Prevention. On a global scale, the problem is greater: there is approximately 400 million cases of dengue per year and are estimated about 40,000 associated deaths. Finding a solution without chemical insecticides through biological control can be a true public health milestone with global impact. Context. There are compelling scientific reasons behind it: in Singapore, a clinical trial with more than 700,000 residents demonstrated that releases of mosquitoes with Wolbachia reduced the risk of dengue by more than 70%. Without going any further, the Debug Project free more than 10 million male mosquitoes per week in Singapore. In Fresno, California, between 7.5 and 14.4 million infected male mosquitoes were released between 2017 and 2018. The result was a reduction in the mosquito vector population of up to 93-95%. In detail. The mechanism behind this “biological pesticide” is relatively simple: only male (non-biting) mosquitoes that have been inoculated with Wolbachia are released. When they mate with wild females that do not have the same bacterial strain, the resulting eggs do not hatch. As several releases occur, the local population is reduced. And what does all this have to do with AI? Google uses artificial intelligence and automation to separate mosquitoes by sex, breed them and release them on a large scale and in a systematic way. Yes, but. All that glitters is not gold. The bacteria does not work with 100% reliability in all cases, as evidence this 2024 study where they concluded that between 6% and 75% of the eggs could produce live embryos under certain conditions. Come on, there is no guaranteed 100% sterility. On the other hand, in 2022 another study from the Verily/Debug team itself Google revealed that automated mosquito release systems were still in “prototype stages or very early versions.” In Xataka | We have spent years inventing everything to get rid of mosquitoes.

Where you can watch the 2026 World Cup depending on the operator you have

by

Let’s tell you with which operators you can watch the 2026 World Cup soccer. The 2026 FIFA World Cup starts on June 11 according to the calendarand if you want to watch the games, you may still not be clear about the network of channels and platforms that offer it. We are going to start the article by telling you What games will you be able to watch for free? on Spanish Television. And then, we will tell you which operators you will have the option to watch the World Cup matches with and what the characteristics of these offers are. What matches can be seen for free RTVE It has the rights to broadcast the World Cup openly. With them, you will be able watch all the matches of the Spanish National Team for freethe opening match on June 11 that pits Mexico against South Africa, the two semifinals, the match for third and fourth place, and the final that will be held on July 19. In total, Spanish Television will broadcast 33 matches through La1 on DTT, and you can also watch them streaming with the RTVE Play application. Being public television, all operators that include DTT in their television packages will allow you to watch the games. The operators that include DTT are Movistar, Orange, Vodafone, DIGI, Jazztel, Yoigo, MásMóvil or Pepephone among others. You can also see them on the OTTs of Movistar Plus and Orange TV Libre. Where can you watch paid matches In addition to the free matches, the rights to the exclusive paid matches belong to DAZN. In total, DAZN has another 71 exclusive matchesand operators such as Movistar or Orange have reached agreements with them to be able to offer the 104 world cup matches to its users. Therefore, the football offer of each operator it remains as follows: Movistar: Users who have contracted the LaLiga package with its additional 36 euros will be able to watch the matches on Movistar Plus. Also those who have contracted the Total Football package of 50 euros per month. If you don’t have one of those packages, your only option will be to contract them for two months and then cancel. We already warned you that either you take advantage of a promotion, or it will be more expensive than hiring DAZN on your own. Orange: Users who have Orange TV and have subscribed to football in their convergent rate will have DAZN Mundial available on Orange TV. The rest will have to buy a package with football to be able to watch the World Cup in its entirety and cancel it later. Of course, if you are going to do it, be careful with the permanence. Vodafone, Yoigo, MásMóvil and regional operators of the former Euskaltel Group (Telecable, R and Euskaltel): Your users will be able to add the Premium package (old Pro plan) of DAZN with DAZN World to their convergent rates, manage the subscription and pay them on the same invoice. Some may have a bit of a discount compared to the official DAZN price if you buy it on your own. If you do not have it contracted, keep in mind that you must maintain the subscription for a minimum of two months and you will have to use the DAZN app to watch the games. Digi, O2, Lowi, Pepephone and Finetwork: Users of these and other operators that do not offer an option to contract DAZN internally will have to subscribe on their own outside the operator. If this is your case, you will have to do it from the DAZN Spain website. In Xataka Basics | Apps for football results: the best 14 applications to receive notifications and see match statistics

Serbia is building the world’s first football stadium that is a garden. China is manufacturing it with surgeon precision

by

It will not be ready for the World Cup that is about to begin nor will we be able to see it at that event because the hosts are Canada, Mexico and the United States, but it is the most striking soccer stadium that will open in 2026: it is the first garden soccer stadium in the world and it is being built in Belgrade. In fact, the latest news is that the Chinese company CSCEC has completed recently the first major steel lift of the structure of the future Serbian National Football Stadium, a colossal mass of 139,000 tons. Stadium construction works are large-scale projects per se, but this one takes the cake precisely because of its dual function: it is a sports venue and an urban garden at the same time, which marks a milestone in urban planning and poses an unusual engineering challenge: hanging entire gardens from a cable structure suspended in height. The first garden stadium in the world. This pioneering garden stadium in the world has a total area of ​​about 76,000 square meters and capacity for more than 52,000 spectators. And although it is located in Belgrade (in the Surčin neighborhood), it is built by two Chinese companies and design it the Spanish studio Fenwick Iribarren Architects. The stadium aims to be more than just a sports venue: the idea is for it to be a public space open all year round, with walking areas, cafes and leisure areas in the surrounding area. The Madrid architecture team has created a very particular façade: it is made up of four suspended rings connected by cables and that house garden areas, arranged on three floors that surround the premises. The normal thing for a stadium is for the structure to be supported from below, with columns, but the Serbian National Football Stadium works as if it were a suspension bridge with cables. It is composed of 44 compression ring beams where each joint must fit with almost zero precision, as CSCEC accountthe Chinese company that is building it. However, this structure has to withstand soil, irrigation and vegetation that will grow over the years. Render of the stadium. Fenwick Iribarren Architects Why is it important. For some time now, large sports stadiums have wanted to be more than just the place where these events take place on specific days: it is now common to see them as a venue for concerts. This project takes another twist: the gardens, terraces and commercial areas are designed to function as a permanent public space, integrating the stadium into the daily life of Belgrade. And it does so by incorporating vegetation in a city where liquid trees are already being tested. As explains the European Environment Agencyurban green infrastructure has been shown to reduce heat island, improve climate resilience and public health Regarding the sporting field, when it is completed (predictably at the end of 2026), it will be the only stadium in Serbia that meets the requirements of both FIFA for World Cups and UEFA for Euro Cups. Or what is the same: without this stadium Serbia would not be eligible to organize these tournaments. Render of the interior of the stadium.Fenwick Iribarren Architects Context. Serbia has been working on the construction of its National Stadium for more than a decade: work began in 2024, but the first concrete proposals came in 2013. At that time the Serbian Football Federation with the help of the British consultancy Mace They designed the project roadmap to meet UEFA requirements and standards. Serbia has decided to become a potential host of top-level tournaments in style and without skimping on expenses: the initial budget in 2013 was 250 million and when work begins in 2024 was already around the billion euros. In detail. Behind materializing this engineering challenge are two top-level Chinese companies common in large infrastructure: the main contractor is Power Construction Corporation of China (PowerChina) and the specialized subcontractor is China State Construction Engineering Corporation (CSCEC), in charge of the design, manufacture and installation of the steel structure. To achieve that brutal precision of just 0.43 millimeters of deviation in 719 meters of beams, they used high-precision laser trackers, 3D digital simulation and a 1:10 scale physical mockup to detect errors before building. Yes, but. The first drawback of this megaproject has already been revealed: so far it has already cost four times more than budgeted. And having a garden stadium is eye-catching, but also more expensive to build and maintain. On the other hand, also there are objections on whether it will be possible to fill the stands of the future venue regularly, something essential to guarantee its profitability. In fact, the Institute for the Study of Urgent Public Procurement and Stadium Affairs of Śrem Kamenica has carried out an analysis which concludes that it will take 420 years to pay off.

“Citizens will behave well because we are recording and documenting everything that happens”

by

“Citizens will behave because we are constantly recording and documenting everything that happens.” It sounds like a phrase taken from George Orwell’s 1984, but Larry Ellison said it during an Oracle financial meeting. It has been two years since he spoke those words and today we can say that this disturbing vision is closer than ever to being a reality. The hyper-vigilant citizen. In September 2024, Ellison projected a future in which mass surveillance would cause us all to behave civilly. The founder of Oracle spoke of cameras everywhere and an AI that would process everything to, if necessary, “report the problem to whoever it concerns. Whether it’s the sheriff, the chief or whoever has to control the situation.” In short, a context of hypervigilance in which any infraction would be recorded and have consequences. This, which sounds like a science fiction scenario, has been silently integrated into the reality of many citizens, and we are not talking about the China social creditbut from the West, especially the United States. The State-Technology fusion. Historically, the tasks of surveillance, security and border control fell to the public institutions themselves. However, the US government has progressively delegated these critical security tasks to technology corporations. At the same time, the militarization of Silicon Valley is a reality: OpenAI and Palantir executives have been named lieutenant colonels and the big tech companies already They do not prohibit the military use of their AI. The government seeks technological efficiency, but at the same time it is ceding enormous power to private companies, with the risk of putting commercial interests before issues such as transparency or democratic scrutiny. The privatization of the US security apparatus has already materialized on various fronts. Objective: deportations. One of the areas in which technology is being used the most is border control and the identification of undocumented immigrants. At the beginning of 2025, the New York Times It said that ICE and USCIS (the agency in charge of processing immigration applications) had spent $7.8 billion on technologies. Many of these contracts were signed under Biden, but under Trump they have been taken to an even more extreme level. Among this arsenal, systems such as ELITE, created by Palantirwhich works like a “Google Maps” to locate potential deportation targets, or the Mobile Fortify app, used by agents to scan faces and check legal status in real time. The persecution is complemented by forensic tools such as Cellebrite to unlock and extract deleted data from mobile phones, rapid DNA tests and the lucrative business of prison operator Geo Group, which forces hundreds of thousands of immigrants to wear GPS ankle bracelets and the SmartLink app to validate their location with daily selfies. Not just immigrants. The alarming thing about this infrastructure is how these tools are powered. To avoid the obligation of court orders, The government directly buys information from data brokers private companies such as LexisNexis and Thomson Reuters, which means that they have data on all citizens, not just immigrants in an irregular situation. During the protests in Minneapolis, where the murder of Alex Pretti, ICE used that same facial recognition software against American citizens who participated in the protests. What was built for deportations is becoming a mass surveillance system for the entire population. Larry Ellison was not wrong at all. The data convenience trap. We have accepted terms and conditions without reading them, installed apps, third-party cookies, shared our lives on social networks… While we gave up our privacy out of pure convenience, thinking that the worst that could happen is that we would be served personalized ads, we were feeding a much murkier machinery. There is tools like Clearview AI that feed directly from the millions of photos that we upload to social networks, or Locate X that takes advantage of apps that collect our location to know where we are. The services that promised to keep us connected are also the ones that keep an eye on us. The ideology behind the code. The leaders of the companies that create these tools promote a techno-utopian vision that quickly leads to techno-authoritarianism. We have the most obvious example with Peter Thiel, founder of Palantir, who said openly “I don’t think freedom and democracy are compatible.” Alex Karp, the company’s current CEO, recently published a 22 point manifesto full of nationalist and militarized ideas. Another defender of this ideology is the investor Marc Andreessen, who published his “techno-optimistic manifesto” in which he proclaims that technology will solve all human problems while stating that ethics, caution and democratic scrutiny are obstacles to progress. We also see it in Elon Musk and his accelerationist visionwhich means that technology must advance without ethical limits or democratic restrictions, because AI is the only tool capable of solving the great problems of humanity. In this context, Larry Ellison’s phrase was not an on-air prediction, it was a warning and a declaration of intent from an elite with a very clear agenda.

220 meters in length and three giant sails of 1,500 square meters

by

When someone says “the largest sailboat in the world”, one immediately thinks of the whim of some millionaire. Jeff Bezos paid $500 million to build his schooner koru 127 meters long and the Russian oligarch Andrey Melnichenko also paid a fortune for his impressive Sailing Yatch A 142.8 meters of length. However, all those luxury sailboats pale when compared to the new titan of sailing that has just been launched in Saint-Nazaire. This is not a private yacht, but a new concept of luxury cruise for millionaires Equipped with three gigantic masts to recreate old-fashioned navigation. The Orient Express leaves the tracks. If we think about great classic luxury trips, it is inevitable to mention the Orient Express as a reference for luxury and glamor trips at the beginning of the 20th century. Now, the hotel company Accord, which also operates one of the lines of the Orient Express, has thrown away the Orient Express Corinthian in the shipyards of Chantiers de l’Atlantique, the same ones where the mythical Normandie liner. The Orient Express Corinthian is not only the largest sailing ship in existence. It is also a form of sea travel that has not been seen for a long time. This is a cruise where 110 passengers sail through the Mediterranean without rushing, assisted by personal butlers on board, with Guerlain spa and avant-garde cuisine with Michelin stars. Three sails, no anchor and an AI looking out to sea. What makes the Corinthian technically unique is not that it has the wingspan of an ocean liner, but rather its propulsion system. It carries three rigid sails of 1,500 m² each, developed by Chantiers de l’Atlantique with a technology called SolidSail. The masts of the Orient Express Corinthian rotate 360 ​​degrees and tilt up to 70º to capture the wind from any angle and make the most of its thrust force. This technology has already been tested successfully in huge freighters to reduce their emissions. Another peculiarity of this luxury supersailboat is that there is no anchor. Instead, the boat uses a dynamic positioning system that keeps it still without touching the bottom. This avoids damaging Posidonia meadows or protected reefs. It also has an artificial intelligence system that continuously monitors the water to detect marine mammals and drifting objects. As support, the sail propulsion system uses a hybrid liquefied natural gas engine. The result, according to the buildersis that it avoids about 9,000 tons of CO₂ per year compared to a conventional cruise of the same size. The luxury of slow travel, from trains to the sea. For a few years now, a part of high purchasing power tourism has turned towards what they call “slow luxury“. A simple idea that recovers all the luxury of the great voyages of yesteryear, where the important thing was not to arrive, but enjoy the journey with the calm that the fast-paced modern lifestyle steals from us every day. The legendary Orient Express train has been the symbol of that spirit of luxury on railsbut now they propose an alternative on the sea. The luxury supersailboat has 54 luxury suites spread over four decks. Each of them is decorated with leather, fine woods and marble. The service includes an exclusive personal butler and you can enjoy the best dishes of avant-garde cuisine in the five restaurants run by chef Yannick Alléno with several Michelin stars to his credit. Vacations within reach of very few pockets. You can now find combined packages where you travel on the Corinthian on routes along the Côte d’Azur, the Italian Riviera and the Adriatic. By 2027, Orient Express introduces new itineraries through Greece, Türkiye, the United Kingdom and northern Europe. To give an example, a seven-night cruise along the Adriatic coast departing from Venice and arriving in Malta in one of the Orient Express Corinthian Suites costs around 39,900 euros. If you opt for one of the most exclusive suites, such as the Agatha Christie Penthouse Suiteof 225 m2 and a 180 m2 terrace and capacity for four guests, can cost up to 198,800 euros on an all-inclusive basis.

It is increasingly common to find jellyfish on Mediterranean beaches before summer. And it’s a bad sign

by

Last weekend and the one before that I tried to swim at the beach. However, upon seeing a few jellyfish I ended up deciding to spend time reading in the sand. The worst of the afternoon was not that. I found more annoying a few teenagers playing soccer a few meters from my towel. Jellyfish, after all, are in their habitat. But it is true that I had never seen in my entire life jellyfish in the month of May. I did some research and discovered that in recent years their arrival in the Mediterranean at this point in spring has become more and more frequent. They are even starting to appear in other waters in which they are not normally so abundant. Logically, the first thought that came to mind was that is related to global warming. The temperature of the Mediterranean has risen at a dizzying rate in recent years. However, I had the feeling that there must be something more. After all, the water has been warming for many years, but this boom in jellyfish populations (known as bloom, by the way) seems more recent to me. To answer my questions, I have contacted Jose Carlos Báez, Chief Program Researcher at the Spanish Institute of Oceanography, CSIC. As I feared, warming water plays a role, but there are even more factors that affect this uncontrolled proliferation that is becoming more and more noticeable. Three phases to give rise to adult jellyfish Although there are small variations between some species and others, in general the reproductive cycle of jellyfish consists of three phases. On the one hand there are the larvae, which float in the water until they find a place to cling to on the seabed. When they achieve this, they move on to the polyp phase, which can last up to a year. When conditions are favorable, the polyp fragments, releasing the ephyras, which are small immature jellyfish that, over time, become the adult jellyfish. The transition from polyp to jellyfish It is known as strobilation and depends on factors such as the temperature of the water, the oxygen dissolved in it or the availability of food. Jellyfish are only released into the water if they are going to be able to live in it. The surface temperature of the water is a determining factor. In fact, it has been observed that with an increase of 1.7°C The rate of asexual reproduction in the polyps of some species is accelerated by 20%. Therefore, strobilation normally occurs at the beginning of summer. It may vary between species. In some it occurs at the end of spring, but it is more common for it to take place from June onwards. According to José Carlos Báez, this is causing “a dilation of the reproductive period“, so we are seeing more generations of jellyfish in a single season. They arrive earlier and leave later. Not everything is going to be global warming The massive proliferations that we are seeing with increasing frequency on beaches are known as blooms. As we have seen, global warming is causing us to start seeing jellyfish earlier and stop seeing them later, but it does not seem to be the cause of the blooms. “It is difficult to affirm with complete certainty that the total biomass of jellyfish in the Mediterranean has increased due to climate change, mainly because we do not have sufficiently long and homogeneous historical series that allow us to compare the current situation with that of past decades,” says Báez. “However, there is evidence that jellyfish blooms, as well as the arrival of large swarms in coastal areas, appear to be increasingly frequent and prolonged.” The problem of overfishing “In a healthy ecosystem, teleost fish eat especially zooplankton, in which ephyras are found,” explains Báez. Among those fish that ephyras eat, sardines stand out, for example. On the other hand, adult jellyfish are typically preyed upon by turtles, but also by large fish such as tunas, to which tuna belongs. All of this, taken together, helps keep jellyfish populations more or less stable. Because of overfishingthere are fewer and fewer predators for jellyfish. There are, for example, fewer sardines being eaten in their ephyra phase and fewer tuna eating adult jellyfish. If we add to all this that more generations of jellyfish are born in a season due to warming water, we have the perfect cocktail for the appearance of blooms. The whiting that bites its tail (pun intended) In 2022, José Carlos Báez’s team published a study in which another less known relationship was described between the populations of jellyfish and sardines or anchovies. We have already seen that fish feed on the zooplankton in which ephyras are found, so they can help regulate jellyfish populations. However, what happens next is not so well known. Adult jellyfish can also feed on the eggs of sardines and anchovies. Therefore, if there are too many jellyfish, they can deplete the sardine population, so there will be fewer of these adult fish to continue feeding on the ephyras. As a result, there are even more jellyfish and we start again. The balance between one predator and another is broken and clearly leans towards the proliferation of jellyfish. Furthermore, in that study a relationship was also found between the proliferation of jellyfish and the decrease in weight of adult sardines. And, in turn, adult jellyfish also feed on zooplankton, which is why they compete with sardines and anchovies for food. If there are many, they do not allow them to feed properly. Not everything is jellyfish in the gelatinization of water With the proliferation of jellyfish, something known as water gelatinization is occurring. Logically, these animals, with their gelatinous appearance, have a great influence. But they are not the only ones who favor that aspect. Other gelatinous animals also proliferate, such as ctenophores. In addition, the water looks cloudier due to excess algae. This is because great eutrophication is occurring in the Mediterranean. … Read more

If you’ve ever wondered how much a massive black hole weighs, the answer is that the Sun next to it looks like a marble.

by

“What am I going to have for breakfast today?” when will this heat pass” and “how much does a black hole“are those three questions that you will surely ask yourself every day when you wake up. For the first two the answer is uncertain, but for the third a group of researchers from Carnegie Science in California has the answer. Because they have just measured, for the first time, the mass of an inactive black hole that dates back to the early universe and they do not give the answer in tons because it is a figure that escapes human understanding. But they do give the mass compared to the Sun and… well, it’s still not something we can assume. The weight of a black hole. The results HE they published this past Thursday in Science magazine and they are clear: a black hole located in the center of the galaxy MRG-M0138 has about 6,000 million times the mass of the Sun. The mass of our star is 2 × 10^30 kg, equivalent to 332,946 times the mass of the Earth. Does this leave you calmer? Surely not because it is like when they tell us that one company buys another for 75 billion dollars: These are such absurd quantities that it is very difficult to get the idea of ​​what it entails, but this thing about weighing bodies around the universe makes sense. Fascinatingly, MRG-M0138 is a massive galaxy whose light has traveled to our sensors from a time when the universe was only about 3 billion years old. This galaxy is no longer forming stars and the central black hole is “quiet.” The scale spacel. To achieve the measurement, the team at the Californian center used the James Webb Space Telescope (JWST) to track the movement of stars around the cosmic giant. It is not the first time that the mass of a black hole has been calculated, but it is the first time that it has been done with one that is so far away (10,000 million light years from Earth, 15 times further than the previous measurement record) and, in addition, it is the first time that an inactive black hole in a galaxy of the early universe. This speaks very well of the benefits of the JWST, which with its sensors allows a very defined image of extremely distant bodies, opening up a huge range when it comes to studying what surrounds us. The problem with sleeping black holes is that they are invisible. It does not emit light, so it cannot be observed directly. So, to “weigh it,” the researchers used a technique that had already been used before: stellar dynamics. Basically, they look at the speed at which stars move near the galactic center and compare that speed to that of more distant stars. In this way, they infer the mass of the black hole. So that. To continue knowing what surrounds us, basically. Because it is not just about measuring the mass of something so distant, but about understanding the formation around it. Thus, this discovery offers new clues to researchers about black holes and galaxies that were born in the early universe. A look at the future by looking at the past. Because, until not long ago, it had been difficult to prove whether there was a close relationship between the central black holes of these very old galaxies. Recent findings suggest that those denser galaxies were sites of rapid black hole growth early in the history of the cosmos. Furthermore, this research will be the basis for future work that will delve into this relationship and, above all, it will also be the basis for analyzing the data collected by the JWST in other similar galaxies. In fact, although the JWST is a good cosmic “magnifying glass”, in Chile the observatory is being expandedThe Bells‘ which is supported by Carnegie Science and will allow studying stellar movements in distant galaxies in much more detail than what JWST offers. In the end, it is about continuing to understand the universe and studies like this allow us to test theoretical methods to understand how massive black holes formed, grew, shaped the evolution of galaxies and, ultimately, became silent giants.
