A gigantic tunnel boring machine 16 meters in diameter is devouring the sea floor under Genoa. It is your solution against traffic

by

Under the port of Genoa, the largest in Italy, there is a machine that aims to devour the sea floor meter by meter. And it does so from the bowels of the earth, 45 meters deep and without interrupting the traffic that passes above it every day. The key is a 16 meter diameter tunnel boring machine that is drilling into the seabed like butter. This is how Italy is solving one of its most entrenched mobility problems, and in the process building the first underwater tunnel of the history of the country. A problem that has been unsolved for decades. Genoa is a city trapped between the Mediterranean Sea and the foothills of the Apennines. It has no room to grow. Its historic center is a labyrinth of narrow streets, and east-west traffic has always been a headache. The solution adopted in the 1960s was to build a gigantic elevated highway, the Sopraelevata Aldo Moro, which crosses the city like a concrete scar. for her About 80,000 vehicles pass through each daybut at a high price: it blocks the view of the sea, generates constant noise and, for many citizens, is a barrier that separates the city from its own port. Its demolition has been stalled for years because no one knows what to do with that traffic in the meantime. Tragedy. The tunnel project was born from an agreement between Autostrade per l’Italia, the Italian Ministry of Transport and local administrations as compensation to the city after the collapse of the Morandi bridge in 2018. That collapse, which claimed 43 lives, left Genoa without one of its main accesses and put the highway concessionaire company under the spotlight. As part of the repair agreement, signed in October 2021, Autostrade per l’Italia, the Liguria Region, the Western Ligure Sea Port System Authority and the Municipality of Genoa agreed to build this underwater tunnel. It is, in practice, the great work of compensation for a city that suffered a tragedy. What is being built. The total route is 4.2 kilometers, of which 3.4 run under the sea floor. It will consist of two separate galleries, one in each direction, each 16 meters in diameter, and will reach a maximum depth of 45 meters below sea level. When completed, it is expected to be Italy’s first underwater tunnel, the largest in Europe (with pardon is being built between Germany and Denmark) and the fourth largest in the world by diameter. Next to nothing. The key: a Hydroshield TBM. Excavating under an active port without interrupting its activity is a monumental challenge. The solution is a TBM tunnel boring machine (Tunnel Boring Machine) Hydroshield type. Each of the two main galleries will be constructed by mechanized excavation with a Hydroshield type back-pressure armored TBM milling cutter, with an excavation diameter of approximately 16 meters. Why this type and not another? In a Hydroshield TBM, the balance in the excavation chamber is maintained through the pressure of water or bentonite slurrywhich stabilizes the excavation face. The extracted material is mixed with these sludge and transported to the surface through pipes. It is the ideal technology for unstable terrain with the presence of water: it allows you to continue drilling without the sea floor crumbling and without the sea entering the gallery. The port above is still working. The gallery measures 15.4 meters in diameter on the outside, but the useful space for circulation is somewhat less, 14.3 meters, because the walls are considerably thick. These walls are built by assembling prefabricated pieces of concrete, as if they were the staves of a giant barrel, joined together with screws and sealed with rubber gaskets so that water does not enter. As if that were not enough, an additional layer of concrete is added inside that further reinforces the impermeability, especially in the sections that are just below the port. The result is a practically airtight tube capable of withstanding the pressure of the sea on its walls. lto logistics of the work. You can’t just place a tunnel boring machine on the seabed and run it. First you have to prepare the ground. The tunnel boring machine was thrown from an attack pit in the San Benigno areaon the west side of the city. To free up that space, Autostrade first had to move a port railway line that ran through there. The railway route, about 700 meters long, has been moved about 70 meters to the south with respect to its previous position, running parallel to the port sopraelevata until passing under it in its final section. Deadlines. Preparation works started in 2023, and work began in March 2024. However, the full tender for the construction of the two main galleries was not approved until January 2026. The specifications set a period of 75 months to complete the entire work. According to the latest Autostrade documents, the TBM will complete excavation work in October 2030, with full completion of the work planned for 2031. Budget. The project started from a budget of 700 million euros, although the mayor of Genoa, Silvia Salis, confirmed that Autostrade now places the cost at more than 1,129 million euros. An escalation of costs that, according to the original agreement between the parties, is covered by a mechanism linked to national highway tolls. Transformation. When the tunnel is completed, it will allow the creation of new green areas (10 hectares, distributed in three public parks) and pedestrian routes that reconnect the city center with the sea. In the San Benigno area, on the new railway gallery already in use, the Lantern Park will be built, which will connect that sector with the city’s historic lighthouse through a bicycle and pedestrian path.

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

by

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

The world wants to verify the age of children so that they do not access social networks. Children’s solution: paint a mustache

by

The United Kingdom presume to have one of the strictest legislations in the world when it comes to protecting minors from social networks. The curious thing is that young people are managing to demonstrate that age verification technology has a unique Achilles heel: an eyebrow pencil. Look, I have a mustache. The British country has been forcing platforms to implement age verification measures in accordance with its Online Safety Act for months. However, a recent study from the NGO Internet Matters reveals that the limits imposed by these platforms are surprisingly easy to overcome. In fact, one of the methods is especially striking, because some children simply use an eyebrow pencil to paint a mustache and thus look older than they really are. Children 1 – Machines 0. This agency surveyed 1,000 children and parents in the United Kingdom and although it showed positive effects after activating these measures, it also made it clear that many children saw these systems as an easy obstacle to overcome rather than as a way to keep them safe. 46% of minors believe that the measures are easy to overcome. Only 17% believe that they are very difficult to avoid, while 19% say they do not know. Source: Internet Matters. Cheating machines is trivial. 46% of the children surveyed indicated that These age verification systems are easy to overcomeand only 17% found them difficult to avoid. There are several methods to overcome these systems, but most are simple. For example, using video game characters like ‘Death Stranding’ to show them in front of cameras trying to verify their age. Also show IDs of other people when asked, or simply use false birth dates. (At least) One in three skips the controls. But not everyone uses these methods: although the aforementioned 46% say that it is easy to overcome these systems and another 17% say that they are neither easy nor difficult, “only” 32% admit to having used some technique to overcome them. Of course, it is one thing that only 32% admit it and quite another that these figures are representative taking into account that they are confessing that they are doing something that they should not do. Methods vary, but many use fake birth dates or log in with their parents’ or siblings’ accounts. Complicit parents. The effectiveness of the Online Safety Act depends largely on the family environment, with data suggesting that at least a quarter of parents are uncooperative. The study indicates that 26% of parents have allowed their children to ignore or overcome these age verification systems, and in fact 17% admit have actively helped their children to evade these controls while 9% simply turn a blind eye. It’s not that big of a deal. Many parents justify this “help” by indicating that they understand the risks of their children accessing these platforms, but prefer to supervise the use of services such as TikTok or video games themselves. The idea: allow your children to bypass restrictions to play with friends or stream, but theoretically under your supervision. The failure of putting doors to the field. It’s not just that age verification systems are easy to overcome: The thing is that they do not eliminate risks completely either. In the Internet Matters study, almost half of the minors surveyed (49%) indicated that they had recently encountered toxic material on the Internet. This makes it clear that even children who do not try to bypass these controls still encounter inappropriate content. There are those who advocate going further and push for the end of online anonymity. Image | Jeremiah Lawrence In Xataka | The EU has just ready its app to verify age on the internet.

The world depends on gas to produce food. Paraguay believes it has the definitive solution thanks to the Itaipú dam

by

In the midst of a scenario of high tension in the Middle East and threatened trade routes, a project in the heart of South America promises to change the rules of the game for global agriculture. The British company Atome has given the final green light for the construction of Villetaa fertilizer plant in Paraguay valued at 665 million dollars, which will completely eliminate the use of fossil fuels in its production. A question of food safety. As detailed Financial Timesthe fertilizer industry’s dependence on natural gas is an Achilles’ heel for the global economy. Traditionally, most nitrogen fertilizer is produced by combining nitrogen from the air with hydrogen extracted from natural gas. However, Villeta will use renewable electricity to separate hydrogen from water (electrolysis). For Olivier Mussat, CEO of Atome, the project’s focus goes far beyond sustainability. “It’s not an ecological story, it’s actually a food security story,” declared in FT. Mussat’s warning is no small matter, since between a quarter and a third of global nitrogen fertilizer exports pass through the Strait of Hormuz. With the recent conflicts, gas shipments have fallen, raising prices and raising alarms about a possible food crisis. For Latin America, an agro-export power but highly dependent on imported fertilizers, the project works as a “structural hedge” against geopolitical volatility. The financial milestone that Wall Street observes. Atome managed to close a financing package that includes $420 million in debt and $245 million in equity. This backing comes from development lenders of the caliber of the International Finance Corporation (IFC) and the European Investment Bank (EIB), along with specialist hydrogen investment fund Hy24. “We have shown that you can actually close and finance a green fertilizer facility on an industrial scale. It has never been done before,” Mussat said. For his part, Pierre-Etienne Franc, executive director of Hy24, explained to the press that having cheap and non-fossil energy sources offers “a route to green fertilizer that will be localized”, making the industry independent of raw material prices dictated by natural gas. The technical feasibility. Green hydrogen has historically been too expensive to compete with its fossil counterpart. However, Paraguay’s competitive advantage changes the equation. The Villeta plant will operate with electrolyzers large-scale powered by the Itaipú hydroelectric dam (shared between Paraguay and Brazil). According to the company’s projections, electricity costs will be just under $30 per megawatt-hour under a long-term agreement. This technical and economic feasibility was enough to convince the Norwegian fertilizer giant, Yara International, to sign a binding contract of 10 years to purchase the entire production of the plant, estimated at around 260,000 tons per year, a detail exhaustively covered by the industrial press. The view from Asunción. For decades, Paraguay has exported its surplus energy generated in Itaipú to its neighbors, Brazil and Argentina, at very low prices. For the local pressAtome’s installation represents a historic paradigm shift. It means taking that clean energy and using it within the national territory to generate local jobs and produce a good with high added value. Although Villeta will represent less than 1% of the global nitrogen fertilizer market when it begins production in 2029, its backers and market observers agree on something fundamental: if the Paraguayan model works, it could become the definitive template for freeing global agriculture from its dependence on fossil fuels.

Having a beer in the sun was the problem. The residual hops from manufacturing it are the solution

by

When you slather on sunscreen, most conventional sun-blocking ingredients are synthetic. He problem is where the chemical UV filters that make sunscreens effective They are endocrine disruptors.can penetrate the skin and are toxic to coral reefs. So the industry has been looking for years for sustainable alternatives that provide that protection while minimizing the environmental impact. A research team from the University of São Paulo has found a natural alternative that also usually ends up in the trash: the remains of hops discarded after brewing beer. The discovery. It turns out that the hops used in beer production, a waste generated on a large scale, can serve to significantly improve sun protection. Through a process of maceration and percolation in ethanol, the bioactive compounds are extracted from discarded hops and incorporated into sunscreen formulations. When they mixed 10% of this extract with the usual UV filters, the resulting sunscreen multiplied its protection factor by more than three: it went from 53 to 178 in laboratory tests. Interestingly, those used hops performed better than unused hops, although the authors admit that the exact mechanism by which this occurs is still unclear. Why is it important. Approximately 85% of the bioactive compounds in hops remain intact in the material discarded after dry hopping (dry hopping), which turns this waste into a functional raw material that today is mostly thrown away or used as feed. Revaluing it as a cosmetic ingredient reduces the environmental impact of the brewing industry, opens a path towards more sustainable and potentially cheaper sunscreens, and fits directly with the principles of the circular economy. Context. Hops contain a family of compounds with proven properties on the skin: reduce inflammation, neutralize free radicals and even stop enzymes that degrade collagen. Especially relevant is xanthohumol, a polyphenol with antioxidant, anti-inflammatory and metalloproteinase inhibitor properties in dermal fibroblasts. The key is how the hops are processed: when added cold after fermentation, without boiling, the xanthohumol is not thermally degraded and remains intact in the residue, which partly explains why reused material is more active than fresh hops. How they do it. The team left From the remains of hops from a craft brewery, he immersed them in ethyl alcohol to extract their compounds, dried the result and incorporated it at 10% into a standard sunscreen that already contained two conventional UV filters. They then measured how much ultraviolet radiation that cream blocked using international reference equipment, the same ones used by health authorities to certify sunscreens. Yes, but. As the research team itself recognizes, all the results are exclusively in vitro, since they used plates and not human skin. Likewise, there are no clinical trials that study whether the cream is stable over time or whether it can cause irritation. Furthermore, it is not clear why it works so well. As says the coordinator André Rolim Baby himself In the note from the FAPESP Agency, stability studies, standardization of assets and clinical evaluation of safety and efficacy will be necessary before any commercial application. On the other hand, the variability in the composition of reused hops (depending on the variety, the dry-hopping process or its origin) complicates standardization: for a filter to be approved by authorities such as the European Commission (EC Regulation 1223/2009) or the FDA in the United States, it is necessary that there be chemical consistency from batch to batch.

The world has an insoluble problem with coal. China has found the solution and it does not involve burning it

by

Decades ago, the world embarked on the decarbonization race. Each country has gone at a pace with nuclear, but gas, hydrogen research and the rise of renewables They aimed to be the impetus to close coal plants. That’s when artificial intelligence arrived and turned the plan upside down. The data centers They need a lot of electricity and, at peak computing, the demand is for immediate energy. This is where coal burning comes in, but in China they believe they have found a solution to avoid definitively bury the coal. Extract energy without burning it. ZC-DCFC. That is the not-so-friendly name that a team from the Chinese Academy of Sciences and Shenzhen University has used. baptized what they call as zero carbon direct carbon fuel cell. The group, led by Xie Heping, has been since 2018 developing This concept is not so much a new way of using coal as a primary energy element, but rather a technique to exploit reserves in deep mines. How it works. To achieve this, carbon is pulverized, purified and introduced into the anode chamber of a fuel cell. On the other hand, oxygen is introduced through the cathode, which causes a reaction in the carbon: an electrochemical oxidation. This process generates electricity directly without combustion, without turbines and without emissions. According to those responsible, the efficiency in energy generation is notably greater than that obtained in conventional energy generation with coal and another advantage is that the system is silent, which also solves the problem of noise pollution that comes with the use of coal. Solving the big problem. The ZC-DCFC also works without CO2 emissions because the high-purity carbon dioxide generated at the anode outlet is captured on site and converted by catalysis into chemical feedstocks such as syngas or compounds such as sodium bicarbonate. But the system has not been made thinking about processing coal in a better way. For that we already have the response in the form of renewables and the green hydrogen. What Xie Heping’s team is creating is a solution to the big problem of harnessing coal from deep underground deposits. not so fast. The idea is to create systems that generate electricity, directly, in the depths of these mines. This way there is no need to launch the very expensive industrial network to bring the coal to the surface and then process it. Electricity would be generated two kilometers deep and it is that energy that is directly transmitted to the surface. Now, they have been investigating since 2018 and are already testing it, but although the project is framed within China’s great plan for the Deep Exploration of Earth and Mineral Resources, there is still a long way to go. This is a long-term plan to achieve carbon neutrality by 2060 and it is already point that these carbon cells are unlikely to come into operation on a large scale before 2045. Either way, if it makes sense for anyone to research alternatives to coal using coal, it’s… China. Despite being the power of renewables and be on top of the nuclear raceit is estimated that 60% of the nation’s electricity comes from coal. They have enormous reserves and somehow they have to be used.

Europe desperately needs coltan for its chips. The solution is in a town in Ourense and depends on a single procedure

by

Galicia hides beneath its soil an indispensable technological treasure for the 21st century, and the machinery to unearth it has already been put into operation. We are talking about the Penouta mine, located in the Ourense town of Viana do Bolo, which is the only coltan mine on the way to being active again throughout Western Europe. This is not a new deposit, since the original operations of this mine They ceased in 1985 and the area was abandoned. Although there was a recent attempt at reactivation by the company Strategic Mineralsthe project ended in bankruptcy. Today, however, this highly strategic asset awakens from its slumber and its long-awaited reopening already depends on one last bureaucratic push that could be resolved before this summer. The penultimate notice. To understand where this mining resurgence is, you have to look at the offices. According to the Vigo Lighthousethe Council of Ministers has just given the green light to Foreign Direct Investment (FDI). This step was vital for the Australian group Energy Transition Minerals (ETM), through its Spanish subsidiary, definitively acquires the deposit. A purchase that has been forged after a public auction in which the firm presented an offer of 5.2 million euros. With the blessing of the central government and the financial muscle secured, the ball is now in the court of the Xunta de Galicia. As pointed out The Voice of Galiciathe operation depends solely on the General Directorate of Energy and Mines approving the transfer of the licenses from the former promoter to ETM. The Ministry of Economy and Industry assures that the process is “very advanced.” Regarding deadlines, the company hopes to be able to sign the deeds in the month of May, or in any case, complete the process throughout the second quarter of the year, inevitably before the month of July. A lifeline for Europe’s technological sovereignty. The Galician exploitation of Penouta is rich in tin and tantalum (popularly known as “black gold” or coltan), critical minerals for the manufacture of electronic components at a time when Europe seeks to depend less on third countries. According to statements by Daniel Mamadou, general director of ETM, collected by The Economistthe company has committed to ensuring that all production “remains available for the development of associated industries within the European Union”, and have already initiated contacts with potential local partners. Added to this is its value as a circular economy model. An EU report a few years ago dedicated an entire chapter to Penoutahighlighting it as a reference in the recovery of critical raw materials from mining waste (slag heaps) from the old exploitation of the 80s, an activity that, in addition, “can help restore the environment.” The open fronts. The reactivation plan will be progressive, where ETM plans to start first with “section B” (the waste dumps), which will allow a gradual incorporation of workers. In parallel, the company will prepare the documentation to request a new license for “section C” (the exploitation of the mine itself) with the aim of starting to extract coltan in 2027. To shorten these bureaucratic deadlines, the company plans to request the declaration of a Strategic Industrial Project (PIE). This care when requesting new licenses is not coincidental, since the judicial front has marked the recent history of Penouta. On the one hand, there is good news for the project: the Provincial Court of Ourense firmly filed a case for alleged polluting discharges in February when it found no evidence of criminality. However, the main exploitation permit of the previous owner was annulled in 2024 by the Superior Court of Xustiza of Galicia (TSXG), considering the environmental impact study on the Natura 2000 Network “insufficient”, a decision that is currently pending appeals before the Supreme Court. The firm that will change everything. The closure of the previous stage of the Penouta mine left 55 families on the streets after the bankruptcy. Today, the scenario is radically different. With Australian financing guaranteed, authorization from Madrid in the pocket and a judicial horizon that is beginning to clear, Galician “black gold” has ceased to be a frustrated project and has become the country’s great mining hope. Now, the entire sector holds its breath waiting for that single signature from the Xunta de Galicia that will put Ourense back on the map of the European energy transition.

The new EU border system is leaving people without flights. Ryanair has a solution: close check-in early

by

From 10 November, Ryanair check-in counters They will close one hour before of the scheduled departure, instead of the 40 minutes that is now allowed. The change implies that the traveler will have to coordinate the time better and go a little more in advance. All, according to the company, in order to avoid problems at security and passport controls. What exactly changes. Until now, Ryanair travelers who wanted to deliver their luggage at the airport had a limit of 40 minutes prior to the departure of their flight. With the new rule, that margin is extended to 60 minutes. In other words: you will have to arrive at the airport earlier and arrange your suitcase more in advance. The measure will apply to all airports where the Irish airline operates. Why does he do it? According to the company itselfthe goal is to reduce the number of passengers who miss their flight due to getting stuck in security or passport control queues. By bringing forward the closing of the counters, travelers with checked luggage would have more time to go through those checkpoints before boarding begins. Dara Brady, chief marketing officer at Ryanair, counted in the press release that the change is especially relevant “during peak periods, when some of these lines at the airport can be longer.” Milan was the best example. Queues at checkpoints are the common enemy that can cause us to end up missing our flight. And the last few weeks have been especially busy around it, because hundreds of passengers missed their flights due to Europe’s new Entry and Exit System (EES). This is the European Union’s new digital border control that forces non-EU citizens (including British citizens after Brexit) to register their biometric data, such as fingerprint and facial recognition, every time they cross a border in the Schengen area. The system was supposed to be fully operational on April 10, but it seems that no one thought that the system would end up being so chaotic. According to reported BBC, on April 16, a Ryanair flight from Bergamo airport in Milan left for Manchester, leaving behind a group of travelers who had been stuck in the border queue for an hour and a half without moving forward. That same day, another airline flight between Tenerife South and East Midlands also left many passengers on the ground. Mplus self-check-in kiosks. The measure comes accompanied by an expansion of self-check-in luggage kiosks, which will be available before October in more than 95% of the airports in its network. These terminals work integrated with the Ryanair application and allow the passenger to check in the suitcase and print the label without going through the traditional counter. The airline claims this will speed up the process and reduce waits. Who it affects and who it doesn’t. According to account airline, this change only affects 20% of Ryanair passengers who check baggage. The remaining 80%, who travel only with hand luggage, will not notice any difference. For this reason, if you travel with Ryanair and plan to check in a suitcase starting in November, take this margin into account and calculate that you will have to arrive a little earlier for your flights.

We have stuffed the Gibraltar monkeys with Doritos. His solution has been to eat dirt as if it were omeprazole

by

On the Rock of Gibraltar, one of the most classic scenes that can be found without a doubt is that of the Barbary macaqueswho seem to be the absolute kings of the entire terrain. Here it is quite likely to see tourists end up stealing a piece of sandwich, chips or a sweet that they have in their hands, especially when the rules are not followed that are marked. But this, which may have its funny point, the truth is that it generates quite a few alterations in the animals, to the point of needing to eat dirt. It has been studied. That a macaque takes a bag of Doritos from a tourist and begins to eat it, among many other types of junk food, is something that has focused the attention of science. And it has reached such a point that it has materialized in a study published in Scientific Reports where numerous continuous episodes of geophagy have been documented among these primates. This is nothing more than the usual consumption of red soil, which is known as terra rossa, and even, in some specific groups, a strange mixture of dirt and tar. Its consequences. What at first glance may seem like simple animal curiosity is actually a survival mechanism, as researchers have found a statistical correlation between the consumption of this junk food, loaded with sugars, salt and dairy, and the frequency with which they eat the earth. In fact, the data shows that this practice increases in summer, when there are a greater number of tourists in the area, and decreases drastically when the influx of people and, therefore, the availability of junk food in the area decreases. Why do they do it? Here we must take into account that the stomachs of these macaques are not prepared for the junk and processed food that humans consume. This is why the earth can act as a gastric cushioning system and can be compared in our minds to a stomach protector. After a heavy meal, macaques use clay to purge themselves, absorb toxins and relieve the digestive discomfort caused by our diet. In addition to providing them with certain minerals that junk food lacks, scientists point out that swallowing dirt helps them try to rebalance an intestinal microbiome that has been altered by the excess of salt and sugar. A cultural tradition. The most interesting finding of this research is that eating dirt is not a mere isolated instinct, but has become an anthropogenically induced tradition of primates. That is to say, we are dealing with a behavior of social transmission, since the macaques learn from each other that eating dirt relieves the belly pain after stealing an ice cream from a tourist. This, logically, is a cultural component of self-medication that has arisen purely and exclusively due to the alteration of their environment at the hands of human beings, demonstrating the great capacity for adaptation that they can have to any situation that comes upon them.

We thought that AI was going to collapse the electrical grid. The solution is to “unplug” it 18 days a year

by

Daily headlines bombard us with the insatiable hunger for Artificial Intelligence, painting a future where data centers will devour our infrastructure. However, reality hides a fascinating irony: the same technology that clutters cables today could be our greatest ally. According to estimates of DeloitteAI will optimize global systems saving more than 3,700 TWh by 2030, almost four times the energy consumed by all data centers on the planet combined. But to get to that stage, you first have to turn on the machines today. And the solution is surprisingly analog. Paweł Czyżak, from the Ember analysis center and one of the most authoritative voices in the European energy transition, sums it up with a simple idea: A data center does not need to operate at full power every hour of the year. In the face of system collapse, the industry’s new survival dogma is clear: “Connect now and operate flexibly.” The heart attack of the network. We have been victims of what we once defined as “tyranny of 24/7”. Algorithms do not sleep and demand uninterrupted supply. This voracity has caused a heart attack in the traditional data epicenters in Europe (the “FLAP-D” markets: Frankfurt, London, Amsterdam, Paris and Dublin), almost completely paralyzing new deployments. The bottleneck is no longer the latest generation microchips; transformers and free electrons are missing. Added to this physical collapse is the bureaucratic one. The European University Institute (EUI) warns that connection queues are a critical funnel: in countries such as the United Kingdom or Italy, the requested capacity exceeds the peak of national maximum demand by more than 10 times. All of this is aggravated by speculative “zombie” projects that block entry to legitimate developers. The obstacles are, as detailed in the recent study by Camus, encoord and Princeton ZERO Laba double wall: there is a lack of cables for day-to-day operations and a lack of clean capacity built to provide backup. Flexibility as a lifesaver. Is it possible to “turn off” part of the AI ​​brain without the system crashing? Yes. A recent trial led by Nebius, Emerald AI and National Grid showed that an AI cluster was able to cut its consumption by 30% in just 40 seconds to relieve the network, keeping critical tasks intact. Even Google already boasts of having reached 1 GW of “demand response” by combining batteries and the ability to move loads between regions. As Czyżak explainsmoving just 5% of the load (the equivalent of a few critical hours per year) unblocks the grid massively. In fact, this strategy would save more natural gas than a country like Denmark consumes in electricity generation, by preventing electricity companies from having to turn on expensive and polluting combined cycle plants to cover demand peaks. For its part, the Camus and Princeton report proposes to scale this with two mechanisms: Flexible connections: The center operates normally 99% of the time, but in the scarce 40 or 70 hours a year of extreme network saturation, it reduces its computing or draws on its own batteries. BYOC agreements (Bring Your Own Capacity): Big tech finances its own clean energy capacity instead of waiting for the state to modernize infrastructure. The combination is magical: it reduces the wait to connect to the network from 7 to just 2 years. For a technology company, this means starting to bill three years earlier, generating net returns of between 1,000 and 4,000 million dollars per site. The citizen will not pay the bill. On a social level, the transition towards this flexible model brings excellent news for the average citizen. The detailed modeling of Princeton’s ZERO Lab confirms that a flexible data center (under BYOC schemes) assumes practically all of the incremental costs it generates to the electrical system. In other words, the billions needed to host the cloud will not be transferred to household electricity bills. On the contrary, by making the most of the existing network instead of building massive new lines, the fixed costs are distributed among more actors. In Spain, organizations such as the CNMC are already applying “flexible access permissions”forcing by law to accept controlled cuts in emergencies to protect the stability of the country. The plug that will rule the world. In the frenetic geopolitical and business race to dominate the future of Artificial Intelligence, the narrative has changed. It is no longer enough to design the fastest microchip or have the most brilliant engineers. Today absolute victory belongs to whoever has a free plug. But rather than desperately burning gas or waiting a decade for governments to bury thousands of kilometers of copper, the industry has found a pragmatic way out. Demand flexibility from Big Tech Not only does it allow them to turn on their servers years earlier; It protects citizens’ bills, squeezes the infrastructure of the 20th century and banishes the dangerous ghost of a Europe forced to relapse into its old addiction to fossil fuels.
