Gasoline hoses have a tiny hole at the end. Without chips involved, it is the smartest piece in the entire supplier

by

If you’ve ever paid attention to the pump while filling up, you may have noticed that it has a small hole located near the tip of the metal nozzle. That little hole is, possibly, the most ingenious piece of the entire set. And it is responsible for the hose “knowing” when to stop adding fuel and stopping on its own with that characteristic click. What exactly is it. This small hole is located at the end of the pipe (the part that you insert into the tank) and is connected to a thin, secondary tube that runs inside the nozzle parallel to the main fuel line. The nozzle uses the fuel itself that is being pumped to create the effect that activates the automatic cut. So to speak, the little hole does not pour gasoline, but rather breathes air. How it works. The key is in a physical principle called the Venturi effect. While the fuel flows at high speed through a narrowing of the duct, a low pressure zone is generated that sucks air through that small hole in the tip. The Venturi effect occurs because The density of gasoline is greater than that of airand it is precisely this phenomenon that causes the dispenser to turn off automatically when the tank is full. The moment of cutting. When the gasoline level inside the tank rises to cover that hole, the tube stops being able to suck in air. When the airflow is cut off, the suction is triggered and creates a vacuum that pulls on a flexible membrane (a diaphragm) housed in the handle of the nozzle. That movement releases a lever mechanism that slams the main valve shut, stopping fuel instantly. The pressure change causes the diaphragm to “jump”releasing the mechanical lever that closes the valve and ending with a click. And as you may have already noticed, the cut occurs even if you continue to pull the trigger. 100% mechanical. This entire system is purely mechanical. There are no electronic sensors, no chips, no batteries. The handle simply generates a slight vacuum at the tip of the pipe, and if that point becomes clogged, a mechanism closes the valve. It is basic physics applied to this little invention that we use in our routine, and that is capable of detecting even a small amount of fuel, blocking the hole to prevent it from overflowing. Security and cuts. This system prevents gasoline from overflowing from the tank, something that would be dangerous (risk of fire) and polluting. But its usefulness goes beyond safe filling. This extraordinary sensitivity is also the cause of those premature and repeated cuts when the jet turns off even though the tank is not full. The most common cause of these annoying cuts is simply a little gasoline splashing back and covers the hole momentarily, activating the mechanism ahead of time. In cars with short filler tubes, a rapid flow can easily flood that column, so the first recommended remedy is usually to reduce the filling rate. The position of the nozzle and the temperature of the fuel also play a role. In Xataka | The United States has the best electric car chargers in the world. Europe has something more important

In 1972 Italy wanted to put an entire city in a one kilometer building. Half a century later he is still paying the consequences

by

The same year that construction of the Corviale complex began, US authorities began demolition by Pruitt–Igoea gigantic public housing complex that had been presented just two decades earlier as the future of the modern city. The coincidence was almost symbolic: while one country demolished one of its great urban utopias, another began to build a new one. A city within a building. During the 1970s, Italy believed it could solve several urban problems at once. Rome was growing rapidly, peripheral neighborhoods were multiplying and public housing was facing increasing demand. The answer It was the Corvialea gigantic residential structure almost a kilometer long designed to house around 8,500 people. Its architect, Mario Fiorentino, did not simply imagine a block of flats, but a authentic linear city where streets would be corridors, squares would emerge from common spaces and daily services would coexist with homes. That vision was intended to demonstrate that architecture could reorganize urban life from its foundations. A utopia that was never completed. The problem appeared before the project was even finished being built. The company in charge of the works went bankrupt in 1982 and many of the essential elements of the original design never came to fruition. The famous middle floor used for shops, offices, services and community spaces was left empty and ended up being occupied by families looking for a place to live. What was to become the social heart of the complex ended up becoming a housing labyrinth improvised. Many of the planned facilities were also never built, leaving the infrastructure that was to turn the building into a self-sufficient city incomplete. When architecture conditions everyday life. Over the years, Corviale began to demonstrate that buildings are not simple containers where people live. Its long corridors, its few entrances, the complex interior circulation and the enormous scale of the complex began to influence the way in which the residents they were related to each other. The elevators are They broke down constantlyforcing thousands of people to travel long distances to enter or leave their homes. The centralized heating system caused conflicts between residentsirregular occupants and administrations on who should bear the costs. Some researchers even described the building as a small town whose governance problems were directly linked to its physical characteristics. From the symbol of the future to the symbol of failure. As the deterioration progressed, Corviale began to accumulate a reputation increasingly negative. For many he became the perfect example of the excesses of urbanism postwar monumental. Its critics described it as a concrete monster, a residential prison or an example of how certain urban planning ideologies had ignored people’s real needs. Illegal occupations, maintenance problems, the presence of criminal activities and institutional abandonment reinforced this perception. for years proposals arose to tear it down completely and replace it with smaller-scale traditional neighborhoods, connected by streets, squares and buildings closer to human dimensions. Giuditto Miele at the groundbreaking ceremony for the Corviale complex The battle to decide your destiny. However, Corviale was never demolished. Unlike many other large post-war European housing estates, managed to survive to demolition attempts. Part of the explanation lies in its increasing symbolic value. What for some was an urban failure, for others represented an unrepeatable piece of Italian architectural history. The building ended up getting heritage protection and became part of the national debate about what to do with the great utopias of the 20th century. The discussion stopped focusing solely on whether the project had worked or not and became a more complex question: how to transform such a gigantic structure without destroying it. Half a century of reforms to correct an idea. The last decades have been marked by an almost constant succession of regeneration projects. International competitions, neighborhood associations, architects and public administrations have tried adapt the complex to current needs. Some interventions have regularized occupied spaces, others have rehabilitated common areas and several seek to recover the pedestrian scale through new public spaces and green areas. No other residential complex in Rome has received public investment so intense and prolonged. The paradox in this case is more than evident: the building that was born to simplify urban life has become one of the most complex regeneration operations in the city. Consequences of a big bet. The story del Corviale It continues to fascinate because it transcends architecture. It is the story of a time that believed that social problems could be solved through great physical solutions and a city that continues to deal with the consequences of that bet. The building, by the way, still standinginhabited by thousands of people and subjected to continuous transformations. For some it demonstrates the limits of grand urban visions, for others, the ability of a community to adapt to an unfinished project. The truth is that half a century later, Rome continues to dedicate resources, time and energy to managing a structure designed to function as a complete city. And perhaps that is the clearest proof that Corviale never stopped being exactly that: a city enclosed within a building.

the largest ballistic attack of the entire war

by

In 1983, during a soviet drill of nuclear attack, thousands of people spent hours sheltering in the depths of the kyiv metro while authorities rehearsed how to survive to a rain of missiles on the city. Four decades later, the same underground stations have once again been filled with families, improvised mattresses and air raid sirens in the middle of a new war over Europe. The night everyone feared. Over the past weekend, Russia launched the major ballistic attack of the entire war in an offensive that for hours turned the Ukrainian capital into a continuous succession of explosions, fires and anti-aircraft alarms. The magnitude of the bombing was not only in the number of drones and missiles used, but also in the type of weapons used: Moscow once again resorted to Oreshnik missilean intermediate-range ballistic system originally designed to carry nuclear warheads and whose mere presence has a strong psychological effect on the Ukrainian population and defenses. For months, kyiv had warned of the possibility of a combined attack designed specifically to overwhelm the Patriot batteries and hit the city with an intensity not seen since the end of 2024. The feeling in Ukraine was that Russia was preparing something differenta show of force intended both to destroy infrastructure and to convey the idea that it still retains the capacity to escalate despite recent setbacks on the front. Oreshnik and the return of nuclear fear. The appearance of the Oreshnik has partially changed the nature of the air war over Ukraine because it functions not only as a conventional weapon, but also as a political tool of strategic intimidation. The missile releases multiple warheads during flight that fall at high speed in trajectories difficult to intercept even for the American Patriot systems, one of the few shields capable of stopping Russian ballistic missiles. Although Oreshnik’s previous releases had caused damage relatively limited and it is believed that they used simulated charges, in Ukraine the problem is not only physical destruction but the normalization of a weapon associated with the Russian nuclear arsenal. The Ukrainian and Western authorities had been alerting of preparations for use and the population of kyiv responded by filling subway stations and underground shelters even before the first detonations began. Wear phase. The attack also exposed a problem that worries kyiv greatly: Ukraine depends almost entirely of Patriot missiles to stop ballistic projectiles and the reserves are increasingly limited after the enormous consumption of interceptors during the war between the United States and Iran. Russia appears to have detected this vulnerability and is using large combined drone salvoscruise missiles and ballistic missiles to force Ukraine to quickly expend extremely expensive and difficult to replace defenses. On this occasion, Moscow launched dozens of ballistic missiles and Ukraine only managed to intercept a relatively small part, a figure that reveals the extent to which the Russian strategy simply seeks to saturate the enemy defensive system through volume and simultaneity. The worrying thing for kyiv is that the math works in the Kremlin’s favor: manufacturing drones and missiles is much cheaper and faster than producing Patriot interceptors. The Russian response. The offensive came just hours after Ukraine will hit facilities Russian forces and attack a base of the Rubicon drone unit in Lugansk, one of the most important unmanned warfare formations of the Russian army. Moscow presented the bombing of kyiv as direct retaliation and Vladimir Putin publicly ordered the preparation of a response after denouncing Ukrainian attacks against supposed civilian targets. However, the strategic context goes far beyond simple revenge. Russia goes through an awkward moment on the front: its ground advances have slowed considerably, Ukraine has managed to attack energy infrastructures deep within Russian territory, and waves of Ukrainian drones have even forced reduce symbolic acts like the Victory Day parade in Moscow. I remembered the new york times that the massive attack on kyiv also seems to respond to the Kremlin’s need to regain psychological initiative and convey that it can still impose enormous costs on Ukraine despite the accumulated wear and tear. kyiv as an eternal laboratory of war. If you like, the Ukrainian capital has become an extreme example of how contemporary wars are evolving: entire cities operate permanently under aerial threat while the population learns to live with attacks capable of paralyzing civilian infrastructure for hours. He bombing damaged subway entrances used as shelter, destroyed buildings, burned markets and left symbolic scenes such as the melted arches of a McDonald’s among the still smoldering ruins. At the same time, the attack showed how the border between conventional warfare, psychological warfare and technological competition is increasingly diffuse. Ukraine is trying to compensate for its industrial inferiority by hitting Russian refineries, logistics centers and drone bases with long-range strikes, while Moscow responds by resorting to a mix of volume, aerial terror and weapons designed to send strategic messages as well as destroy targets. The precedent that worries the West. Finally, the Financial Times reported that there is a growing feeling in kyiv that Russia is using Ukraine as a scenario to test how Western defenses react to massive and prolonged attacks with advanced ballistic missiles. Zelensky insisted before and after the attack in which the repeated use of the Oreshnik and the continuity of this escalation create a global precedent for future conflicts, especially at a time when the United States and Europe observe with concern the arsenal expansion similar in countries like China, Iran or North Korea. From that perspective, what happened in kyiv would not only affect Ukraine: it also serves as a warning about how they could future wars develop between powers with great missile capabilities and limited anti-aircraft defenses. The most uncomfortable conclusion for the West is that Russia seems convinced that it has found a relatively effective formula for wearing down modern defensive systems through massive, repetitive attacks that are increasingly difficult to contain.

There is a Chinese manufacturer eating the entire electric motorcycle pie. And his next goal is Europe

by

The increase of fuel prices caused by the iran war It is being the perfect excuse for one of the most relevant electric motorcycle manufacturers in China to focus away from its territory. Given the growing demand for economical and electric motorcycles outside Asia, the focus is clear: Europe. Yadea. Yadea is, by sales volume, the world’s largest manufacturer of scooters and electric two-wheeled vehicles. Its success is given by the very high demand for this type of motorbikes both in China and in Southeast Asia and South America. And now it’s time to conquer Europe. Since the conflict with Iran raised oil prices and created obstacles to its transit, international sales of Yadea They are growing at a rate of 70% year-on-year compared to 2025. The new. Yadea is not a new player in Europe. They have been present in Spain since 2022, distributing affordable mopeds and electric motorcycles. A discreet operation that wants to begin to consolidate and grow starting this year. Yadea is closing the opening of a factory in Hungary to produce within the European Union and protect itself from tariff tightening. It is not a new practice: China is starting to manufacture in Europe to make their products competitive, and the electric motorcycle is no exception. Why it is important. Of the almost 60 million electric scooters sold in China, 16 million correspond to Yadea. If there is a manufacturer with enough muscle and knowledge to flood Europe with two-wheeled vehicles at an affordable price, it is this one. Why now. Wang Jiazhong, vice president of Yadea, has made it clear in his statements that the current situation is the best possible opportunity to begin expanding into more markets. “The situation in the Middle East presents a good opportunity for us to enter the market and guide consumers towards the use of our electric vehicles, as they can clearly feel how much fuel prices have increased.” Not so fast. Europe is a peculiar and complicated market for electric two wheels. It represents around 9% of global volumes and is skewed towards premium models. It is not a volume market like Asia, at least today. Quite the opposite happens with the combustion motorcycle: China is sweeping and soon the top 3 best-selling motorcycles will be led by Chinese motorcycles. Therefore, the company is exploring joint ventures and collaborations with local companies to adapt their offer culturally and aesthetically. What giants like NIU, Super Soco or Silence have not achieved (example of the resounding failure of the electric motorcycle in Spain, with the SEAT MO), Yadea wants to achieve it.

The energy jets from black holes are so powerful that they can reshape entire galaxies and now we know how to measure it

by

It is always said that black holes They gobble up everything that comes close to themfrom matter to light. However, this is not entirely true. In some cases, there is a fraction of particles and energy that, instead of falling inside, does the opposite. It is ejected in the form of jets, known as jets. Although there are some hypotheses about this, the reason why this occurs is not completely known. What is known is that these jets are so powerful that they can even influence the evolution of galaxies. The problem is that it is known that they are very powerful, but not how powerful. Until now, no one had been able to directly measure the power of these jets. However, an international team of scientists has achieved measuring these jets around a specific black hole, thereby opening up a very interesting range of possibilities. The data. These scientists have studied the Cygnus X-1 systemcomposed of a black hole and a blue supergiant star orbiting each other. Using a very novel method, they have discovered that the energy of the jets leaving the black hole is equivalent to that of 1,000 suns. They have also observed that they move through space at a speed of 540 million kilometers per hour and that 10% of the energy that is initially formed in the fall towards the black hole is converted into jets. The background. Until now, no one knew how to measure the power of a black hole’s jets. The only thing that was done was to measure the scars they left in space using calorimetric methods. When freed, they can leave in their wake hot spots and holes in the intergalactic medium. However, As explained in an article by Interesting Engineeringthis is something like wanting to measure the power of an engine by observing the treads of the car’s tires. The important thing is to directly analyze the machinery. And that is precisely what has been achieved now. Indirect measures. In systems formed by a black hole and a star, the black hole feed little by little gas surrounding the star. As it approaches it, the gas begins to rotate faster and faster, generating a lot of heat and energy. Part of that energy does not fall into the black hole, but instead jump outward, forming the jets. In turn, the star releases very intense flows of particles, which give rise to what is known as stellar winds. Those stellar winds can interact with the jets and bend them. And there is the key. The jets cannot be measured as such, but the resistance they offer to being bent by stellar winds can be measured. For example, we can know how strong a person is by analyzing his or her ability to beat someone whose strength we do know in an arm wrestling match. Trajectory changes. The overall trajectory of the jets depends on the momentum flux of both the jets themselves and the winds. Since the momentum flow of the wind can be calculated, it is enough to analyze the trajectory to solve the unknown. The data can also be further refined with a series of computer simulations. The result is a fairly rough estimate of the power of the jets. There are limitations. The biggest limitation of this study is that only one black hole has been analyzed. The procedure would have to be repeated with more jets in more black holes to check if there is a trend and, therefore, if the method is valid. Galactic evolution. Since jets from larger black holes can significantly affect galactic evolution, this method could be very useful to better understand how galaxies form. That is why it is important to move on to the second step and check if the method is reproducible, especially with larger black holes.

NASA has captured how an entire lake in Canada disappeared in just 15 days. Science has a disturbing explanation

by

Seen and unseen. In the spring of 2025 something happened in central Quebec: an entire lake disappeared in a matter of days. Lac Rouge, a 1.4 square kilometer body of water located in the Lac-Walker region of Sept-Rivières, a popular hunting and fishing area in the Waswanipi Cree First Nationdisappeared. It did not dry out little by little as a result of a prolonged lack of rain as for example happens to Moroccoit was something abrupt and silent. What you see on these lines is the before and after photographed by the Landsat 9 satellite NASA from space with a margin of one year (June 2024 on the left and June 2025 on the right). That a lake disappears is scientifically interesting, as is the list of suspects: the shores have soft geology, the terrain has been suffering from forest fires for years, there is a lot of logging and also melting ice. Where is the trick. What happened to the lake. The first sign was a destroyed road, as reported by local people who used it to move around the area: the access road was completely destroyed by water, as NASA explains. CBC echoes the subsequent investigationwhich revealed that the land surrounding the lake had collapsed and that Lac Rouge had been emptied. The lake had water on April 29, 2025 but was completely dry on May 14. I mean, It dried in just 15 days. At that time, the local administration released a statement alerting of the event. But the water didn’t disappear, it just moved around. Instead of following its usual outlet channel, it opened a new channel to the northeast, crossing a 10-kilometer chain of lakes and wetlands until it reached Lac Doda. If you look at the after photo, you will see that it left a mark in the form of light brown sediments. The explanation. Science explains this mechanism called outburst flooda flash overflow flood: a portion of the lake shore suddenly gave way and water quickly escaped through that gap instead of overflowing into existing river channels. He NASA Earth Observatory confirmed that it was the east bank that gave way, originating that new route. This phenomenon is relatively common in lakes of glacial origin with unstable ice barriers, but rare in a lake like Lac Rouge, whose barrier is made of soft sedimentary soil. The underlying physics is common in basin hydrology: a coniferous forest absorbs between 20% and 50% of the rain it receives, according to this meta-study published in Nature. If there is no vegetation cover, the water reaches the soil directly, saturates it and weakens those banks. Hydrologist Younes Alila, from the University of British Columbia, summarizes it like this: Any ground disturbance (e.g. fire, logging or forestry) raises the water table and keeps it high for longer, increasing the risk of extreme flooding. There is no Lake Ninio left, only Masibón. POT Why is it important. Because Lac Rouge is not an isolated case: it is a warning. Climate change is making fires more frequent and melting more irregular, as the IPCC climate change expert group explains in his AR6while intensive logging continues to weaken soils. The combination of both factors in basins with soft geology favors the appearance of these poorly studied and difficult to anticipate events, as warned by a study on the boreal forest and climate change published in Springer Nature. In this case, the direct blow is suffered by the indigenous communities. More than 600 communities depend on the Canadian boreal forest for their livelihood, according to the Boreal Conservation Foundationand events like this disappearance drastically alter the territory’s ecosystems and activities, such as hunting and fishing, from one day to the next. The list of suspects. Considering these risk factors, Lac Rouge had all the cards: The fire. In 2019 and 2023, areas near the lake burned. The 2023 fire was Quebec’s worst in more than a century: it burned 4.5 million hectares, according to this study published in the Canadian Journal of Forest Research. The Guardian echoes from the Quebec Cree forestry department, which concludes that those fires eliminated much of the mature vegetation cover in the Lac Rouge basin, including that bank that gave way. Furthermore, the fires can reduce infiltration and increase runoff. Intensive logging. After the fires, logging companies obtained wood by scarifying the land to facilitate replanting, which worsened even more the hydrological degradation of the basin. The thaw of 2025. The winter of 2025 snowed more than normal and the thaw was rapid, generating a volume of water that those weak banks could not contain. Natural or provoked? The Quebec government classified it as a natural event and did not investigate further. Their argument: Their own forestry studies say that if less than half of a watershed’s forest is damaged, the risk to rivers and lakes is minimal, as Sigma Earth collects. International experts and the Cree community do not accept it: these studies do not take into account that in Lac Rouge the damage accumulated in layers or that climate change makes all this happen with more frequency and intensity, according to the IPCC in its Sixth Assessment Report. It was probably a combination of everything: soft soil and weak shoreline set the stage, rapid snowmelt was the spark, and decades of logging and fires made the system much more fragile than it otherwise would have been. As points out Sigma EarthLac Rouge can be a warning of what is to come if the way this territory is managed is not changed.

An AI agent deleted a company’s entire database in nine seconds. Then he confessed how and why

by

Jer Crane is the founder and CEO of the platform PocketOSwidely used in vehicle rental companies. Some of these companies have been using PocketOS for years and according to him “they couldn’t function without us.” A few days ago, a programming AI agent that they use in the company deleted their entire database in their production environment (the one used by clients) and also deleted all backup copies in one fell swoop. Then he confessed what he had done. Too powerful API key. The destruction of that database was not a human or syntax error. The AI ​​agent used—Cursor, with the Claude Opus 4.6 model—was working on a routine task but encountered a problem: an API key to complete the task was incorrect. What he did from then on was find another different key that was unrelated to that task but also had much greater privileges for accessing and executing commands on PocketOS systems. When they created it on the AI ​​platform they use (from the company Railway) the system did not warn them, but said API key had the capacity to do very dangerous things. And he did them. Nine seconds and an absolute disaster. What the AI ​​agent ended up doing using that API key was running a delete command that didn’t ask for confirmation or check the environment. In nine seconds they were left without their production database and without copies of volumes they were using. Without physical firewalls, the AI ​​wreaked havoc, but there was more. Mea culpa. The most disturbing thing about the incident is that Crane asked the machine for explanations after the deletion, and the AI ​​had no problem confessing. Far from blaming the deletion on a technical problem, the AI ​​model wrote a full confession in which it admitted to having knowingly violated all its security barriers. The agent stated the following verbatim: “I assumed that deleting a staging volume via the API would only affect staging. I didn’t check. I didn’t check if the volume ID was shared between environments. I didn’t read the Railway documentation on how cross-environment volumes work before running a destructive command. Also, the system rules I operate under explicitly state: “NEVER run destructive/irreversible git commands (like push –force, hard reset, etc.) unless explicitly requested by the user.” Deleting a database volume is the most destructive and irreversible action possible—much worse than a forced push—and you never asked me to delete anything. I decided to fix the credentials issue on my own, when I should have asked you first or looked for a non-destructive solution. I broke all the principles you told me to do: I guessed instead of checking. I performed a destructive action without being asked. Railway on the behavior of volumes in different environments”. Thus, the AI ​​model admitted that it preferred to “fix” the problem on its own without asking or consulting the technical documentation. Railway in the spotlight. Crane explained that Railway’s own architecture gives rise to this type of disaster. This provider, he explained, causes backup copies to be stored on the same volume as the source data. Deleting the parent container deletes all those copies. Added to this is permission management in which an API key to manage execution domains ends up having privileges to execute destructive operations without asking for confirmation. Railway CEO’s response. Jake Cooper, CEO of Railway, published hours after the event an answer which is worth reading because it goes beyond usual crisis management. Cooper acknowledges the facts: the user gave the agent a token with absolute privileges, the agent called the function that handled the data erasure, and Railway executed it as it was designed to work. But Cooper also does something unexpected: he does not blame the user. A new AI user profile. Instead, he describes what he calls a “new type of creator/builder” that is emerging, someone who doesn’t 100% verify AI responses, doesn’t fully master how APIs work, and doesn’t have a classical engineering background, but who wants to build things and try some. vibe-coding. From there he indicated how the company there was taken measures for avoid future incidents like this. This message points to a real problem: the industry is offering AI agents assuming that users are classically trained engineers, when the profile that these tools are adopting is radically different. Courses has already suffered these problems. Cursor is also guilty of these types of problems, Crane argued. This manager linked to several incidents previous in which those deletions were repeated information and other destructive operations of AI agents. An article in The Register accused the platform of having “better marketing than programming ability“. Return to the analog era. Those nine seconds cost the car rental companies dearly, which found themselves this past weekend with customers arriving at their offices without having any record of who they were or what cars they had reserved. PocketOS engineers spent hours rebuilding the booking system from Stripe payment histories, email confirmations, and calendar integrations. PocketOS had a full backup from three months ago, but Railway also maintained secondary backups and finally could help recover all the information. Lesson learned. The PocketOS case leaves a clear warning for the entire technology sector. Crane proposes that erasure operations that AI models can never complete on their own. For example, using SMS codes or other two-step verification methods for such actions. It doesn’t seem like a bad idea in light of events, and we may start having to think of AI as a security risk… in certain scenarios. Legal liability. With US legislation in hand, the responsibility almost certainly lies with the user, that is, Crane. Cursor or Anthropic’s terms of service transfer responsibility for use to the user of these platforms. Anthropic, for example, sells access to an AI model, not guarantees about what that model will do in specific contexts. There is no legislation on autonomous AI agents, something that of course remains pending and that for example the European AI Act I … Read more

Excess control is triggering the anxiety of an entire generation of children

by

They are there for everything. They solve problems before they appear, supervise every school assignment, do every basic procedure, intercede with teachers and leave no room for failure. This description, which for decades has been disguised as ‘unconditional love’ and ‘protection’, for science is simply helicopter parenting. A way of being parents that, although it seems to be very beneficial for the little ones, the reality is that it is taking its toll on the autonomy and emotions of current generations. A confirmed epidemic. When researchers look at the impact of helicopter parenting on a large scale, there really isn’t much of a doubt. For this we can go to a recent Norwegian systematic review which analyzed 38 independent studies, where it was found that between 70% and 90% of the research points to a relationship between excessive parental control and mental distress. And, on the other hand, no study pointed to a reduction in stress. This is reinforced by a extensive meta-analysis of 53 studieswhich shows that this predictive style drastically reduces self-efficacy, worsens academic performance and increases different mental illnesses such as depression and anxiety in young people. No room to mature. The consequences of constantly “flying over” your children’s lives reach their tipping point when they reach university or enter the job market, where they suddenly have to mature overnight to face the usual problems without parental protection. Although we have already seen some Spanish universities asking parents not to go to higher education centers to claim in the name of their children that they are of legal age. And that these generations that have been so protected is later translated in less personal determination, a greater fear of intimacy when faced with something difficult and problems of social integration. The fact of not having faced frustrations in controlled environments because they have been avoided, ultimately leads to a fear of failure and, therefore, an avoidance of facing problems. Ultimately, maturation towards a functional adult is delayed. The academic impact. In this sense, already in 2017 a large study pointed out that university students with “helicopter parents” report lower academic performance, with worse social integration and, above all, with greater dependence on medications such as anxiolytics to deal with the psychological discomfort caused by the new reality. The figures behind it. Here, a recent work carried out with 697 Turkish adolescents pointed out that mothers have overprotective attitudes in 15.% of cases, compared to 8.8% that corresponds to fathers. Furthermore, the problem has early roots, since longitudinal studies show that high parental control is capable of predicting future depression in children. since 11 years old. And in the Spanish context, some analyzes suggest that structural factors such as continuous intensive work hours combined with pressure for academic success outside of school may be aggravating these patterns in current generations, creating a perfect breeding ground for overprotection. The mental cost. The psychological mechanism behind this emotional disaster is well documented and indicates that helicopter parenting frustrates the most basic psychological needs of minors, and above all autonomy. By removing them from different situations, the message sent to them is that they are not capable of doing it on their own, causing their self-esteem to plummet and they fail to value their abilities. This, in complicated situations such as decision-making in adulthood, is where the true effect of this overprotection will be seen, since it has always been resolved. And this is something that will mark them a lot. Images | freepik In Xataka | Adolescents up to 32 years old: neuroscience explains why the brain takes much longer than we thought to mature

We just found an entire ecosystem hidden under the ocean crust

by

For decades, science believed it was clear how life worked in the ocean abysses and pointed out that around the hydrothermal vents, which are the classic volcanic chimneys that spit out boiling water, oases of strange creatures flourished on the surface of the seabed. But a recent expedition has broken our schemes and it points out that life not only clings to the surface of these chimneys, but also hides beneath the earth’s crust itself. As we have seen. To achieve this featthe expedition named under the “VentUnderoworld” project entered the waters of the Pacific aboard the research vessel Falkor. But the researchers’ eyes were not enough, they had to use the robot SuBastian ROV submarine. And with this equipment the researchers did something that is rarely attempted: physically lift fragments of the oceanic crust around the hydrothermal vents. And in that underwater “underworld,” a vibrant macroscopic ecosystem thrived. What was seen. Until now, science assumed that benthic animals at these depths lived exclusively at the interface between the ocean floor and water. However, the images and samples collected confirmed the presence of live animals in these underground caves. And the great protagonist of this discovery is the Riftia pachyptila, which is nothing more than a huge tube worm which can measure more than two meters. Organisms that are famous for lacking a mouth and stomach and depending on the bacteria on the seabed to feed themselves while they were living and growing prosperously protected under the crust. But they were not alone, since they also found snails and a complex network of invertebrate animals. How they arrived. One of the great mysteries surrounding marine biology was how tube worms managed to colonize new hydrothermal vents so quickly after a volcanic eruption, especially due to the high temperature it reaches. This discovery provides the missing piece of the puzzle. Here the study concludes that there is a fluid connection between surface and subsurface ecosystems, and this causes the larvae of these animals to travel through hydrothermal fluids below the seabed, moving through cracks in the oceanic crust to colonize new areas from bottom to top. That is, the interior of the crust is not only a refuge, but a kind of underground “highway” of life. A new paradigm. This discovery is not something minor, since if these hidden cavities are inhabited in the Eastern Pacific Ridge, it is very likely that this underground ecosystem extends over a large part of the world’s underwater mountain ranges. In this way, expanding the “biosphere” into the interior of the crust means that the habitable volume of our planet has just become much larger, proving that there are still many mysteries here on our planet to be discovered.

The Pentagon wants to invest $54 billion in drones. It is more than the entire military budget of countries like Ukraine

by

The defense budget that the Pentagon has presented for fiscal year 2027 amounts to $1.5 trillion. It is the largest year-on-year increase in military spending since World War II, but in that colossal figure there is another that deserves special attention. This is the $53.6 billion allocated exclusively to drones and autonomous warfare technologies. That amount alone exceeds the Ukraine’s full defense budget either of countries like South Korea or Italy. Spain is even further away. autonomous defense. The money for this specific program will be managed by the Defense Autonomous Warfare Group (DAWG), an agency created at the end of 2025. In the 2026 budget it received 226 million dollars, but in 2027 that figure would be multiplied almost by 240. The United States has realized the relevance that drones have gained in war conflicts and wants to be prepared for this new era of defense. Obsolete investment. The Pentagon itself recognized something striking: the vast majority of the money requested will be used to buy technology that already exists, not to develop future solutions. One of the top officials of the Joint Chiefs of Staff, Lieutenant General Steven Whitney, admitted that technological evolution on the battlefield currently happens in weeks, not years. It’s like admitting that what you buy now may become obsolete almost immediately. Ukraine showed that change has changed. The urgency of this budget does not come from nowhere. The war in Ukraine has rewritten the rules of modern combat In such a way that there are many countries that are processing how to assume these changes. Iranian Shahed droneswhich cost about $20,000 per unit, have proven capable of saturating air defense systems that cost hundreds of times more. Relatively affordable quadcopter drones have destroyed multi-million euro tanks and armored vehicles. Defense budgets in 2025. The US already spent 921 billion dollars last year, this year it wants to spend 50% more. Everything goes very fast. The speed of tactical adaptation on the Ukrainian front has been so high that innovations and tactics that work in January may be obsolete by March. Not because someone has invented something better, but because the adversary has found a way to counter those strategies. The Pentagon has reached an unusual conclusion: the traditional model of weapons acquisition that operated in cycles of years or even decades is structurally incompatible with the speed at which current war conflicts are developing. The irony of the Shahed. Among the most striking details of the budget is the confirmation that the American army has adapted the technology of the Iranian Shahed dronewhich is the same one that has been attacking cities and energy infrastructures in Ukraine for years. The US has done reverse engineering of your adversary’s design to incorporate it into your own arsenal. This clearly illustrates the current war reality: the origin of the technology does not matter, but its effectiveness. Risks. This tension between “we have to spend more” and the speed at which it is necessary to adapt to this reality poses an enormous risk. Buy en masse what works today guarantees that solutions will be available tomorrow. The problem is that these solutions may be technically inferior to those that the adversary has developed in the meantime. The same thing happens if you decide not to buy anything until you have the perfect technology, because that means arriving late (or not arriving at all). It is a dilemma similar to that of technology companies and their investment in infrastructure: they have to buy solutions now that they know that they will end up being obsolete in the short or medium term. Final approval is missing. The US Congress will have to approve the budget, which introduces an important political variable. Beyond that, there is a fundamental question in those 54,000 million in this budget. If drone technology evolves in weeks, there is no money that will be able to buy that adaptability to the modern battlefield. And that even with this immense budget superiority cannot be guaranteed makes clear the sign of the times.
