The brain asks for ultra-processed foods when it has nothing to do and science thinks it knows why

by

There is a fairly classic scene in the lives of many people: not being hungry but wandering around the kitchen, opening the refrigerator, looking and closing it. Minutes later, this operation is repeated. The final result? End up eating something we probably didn’t needwhich is what can be popularly known as ‘gluttony’, but nutrition science has a more precise term: emotional eating. Investigation. Reference researchers in Spain such as Dolores Corella and Jordi Salas-Salvadó from CIBERobn, have focused on how factors more than calorieslike emotions or genetics, determine our weight. And the conclusion is quite clear: boredom is as real a metabolic risk factor as sugar. The boring brain. When we get boredthe brain detects a stimulation deficit that it tries to compensate with the fastest route to pleasure. And this is where the ultra-processed darlings come in. In this case, science indicates that these foods not only nourish us poorly, but activates dopaminergic reward circuitsin a very similar way to how certain addictive substances do. In this case, we have, first of all, a stimulus that is boredom that causes our mood to drop. Here the brain looks for a quick peak of dopamine and an apple is usually not enough, but rather it looks for fats and refined sugars, since their consumption causes a peak of pleasure followed by a sudden drop. Something that promotes excessive consumption and therefore favors gaining weight. The danger of getting bored. Not having things to do during the day or even at night, the truth is that it can be the ideal seed for consuming more calories than necessary. And above all, boredom tends to attack more strongly at the end of the day, when obligations end and this is where “boredom eating” collides head-on with chrononutrition. Researcher Marta Garaulet has shown that the moment in which we eat is critical, since snacking out of boredom after 9:00 p.m. is metabolically disastrous, especially in Spain. Why Spain. We Spaniards have a much worse time eating for boredom beyond 9 at night due to a genetic load in half of the population related to the MTNR1B gene. In this case, whoever has this gene and eats late, the consequences are quite clear: the body secretes less insulin and tolerates the glucose that we are introducing less well. The result here is that what is eaten due to nocturnal boredom it makes you fatter and more inflammatory than if you eat during the day, due to the desynchronization of circadian rhythms and the enzymes necessary to process food. How to counter it. If boredom is the trigger for this situation and ultra-processed foods are the gasoline, the solution to break this vicious circle is in PREDIMED studies. In this case, they pointed out that increasing fiber intake through fruits, vegetables and legumes improves glucose regulation. Something that enhances the reduction of glucose drops that can encourage the brain to eat some sugar urgently. In addition to this, the PREDIMED study confirms that the Mediterranean diet Supplemented with extra virgin olive oil (EVOO) or nuts, it reduces anxiety about eating. Unlike ultra-processed foods, which leave you wanting more, a handful of nuts activates long-lasting satiety mechanisms that prevent us from falling into eating a muffin or chocolate ice cream during the night. Routine vs. chaos. Since intermittent fasting lacks solid long-term evidence, experts like Salas-Salvadó suggest focusing on marked routines: bringing forward dinner to extend your overnight fast naturally. Having a fixed schedule reduces moments of “down time” where hunger attacks due to boredom. With all this, what has been achieved is that the brain does not adapt to situations with high levels of dopamine, such as a time of large, very copious late-night dinners. That is why the strategy is not about prohibiting, but about understanding that when you open the refrigerator at eleven at night without hunger, it is not the stomach that speaks but the brain looking for the entertainment it needs.

The technology industry has been searching for the “next smartphone” for a decade. Now he thinks he found it with AI

by

In the last decade, wearables have become intrinsically associated with health care and sports. And although in 2025 we can make the same association, there are a growing number of companies and devices that have committed themselves to turning them around to turn wearables into vehicles for AI. The leaders of some of the main big tech companies already They have glimpsed the end of the mobile and between the options (in practice, still very green) these wearables with AI appear, which today are more of a complement. In search of the new iPhone. In any case, the industry has been looking for mass hardware after the smartphone for almost two decades. The glasses seem to start by advantage, but the initiatives are many and very varied. In any case, it is no longer just about becoming the winning format, it is about materializing a device that covers needs yet to be defined and where the smartphone has set a very high ceiling. In fact, smartwatches have not come close to overshadowing it. AI glasses have an advantage. Of course, they are the best positioned. In the past CES 2025 we saw ‘smart’ glasses (although that semantics typical of the era of the failed Google Glass has already been banished in favor of the surname ‘with AI’) even in the soup with the promise of immersive and hands-free experiences, but Meta is the one who has landed and sold its product best. Makes perfect sense: Mark Zuckerberg himself has stated who believes that glasses are the ideal format for AI. And for Meta, AI is his new Multiverse. After all, as we have seen, glasses are a discreet and convenient way towards multimodality: visual, through their lenses; and oral, with its integrated microphones and speakers. But it doesn’t matter if we talk about Meta’s glasses or those of Googlethe new glasses smart They no longer look like a hulk, they are designed to be worn all day and their purpose is to interact with AI. Pendants, pins and everything else. Other gadgets that accompany you throughout the day for constant listening come into this mixed bag: from the Bee AI bracelet to the LimitLess pendants or Friend passing through the ring Stream Ring or the difficult to describe Plaud NotePin: it looks like the capsule of Xiaomi bracelets and as such, it can be worn on the wrist, on the neck and even as a tacky pin. These initiatives have not gone unnoticed by the large companies, which have made a move by opening their portfolio: Bee AI bought Amazon in summer and LimitLess did the same Goal just a few weeks ago. old acquaintances. AI is also being integrated into existing devices: Samsung and Google have put Gemini on their WearOS watches, Garmin has a premium subscription to analysis with AI for its watches, Fitbit is testing an AI trainerthe same thing that Apple does with its Watch or the AI translation on AirPods. Even the rings Oura they have their advisor with AI. Every breath you take…We mentioned above that AI glasses were born to be worn all day, something that can be extrapolated to the bulk of the devices that we have been listing. For AI assistants to work well and offer something extra on the mobile, they need to know a lot about the user and there is no better way to do this than on a wearable that is with you 24/7. Disturbing but true. In this field there are unknowns such as what format will be successful and whether it will be as successful or more successful than the smartphone (even if it is buried), but there are two unquestionable facts: that there is a war to have hegemonic AI among big tech and that the industry has seen wearables as the ideal vehicle to implement it.

Exynos had been the ugly duckling of chips for years. BMW thinks the opposite.

by

When choosing a high-end Samsung, the dilemma between betting on the Exynos version or the Qualcomm version has always been clear. In fact, until just a generation ago Samsung reserved its chips Exynos for the “non-Ultra” models, and provided its flagship with Snapdragon Elite on duty. Its chip division has been in crisis for almost a yearbut the latest leaks point to the comeback being close. Meanwhile, the company has a plan to revitalize the income of this business area: bet on the automotive industry. bmw. According to Korean sourcesBMW has chosen the Samsung Exynos Auto V720 to give life to a very important vehicle for the German brand: the next iX3. It will be the first electric car to use this platform. One of the current wars in the automotive sector is precisely to lead in infotainment systems, and there the processor plays a fundamental role. The Exynos Auto V720. This processor will be manufactured in a five nanometer process, and its announcement will be imminent according to the source. It is not the first time that BMW has opted for the Korean company, since flagship vehicles such as those of the Series 7 of the company have been betting on platforms such as the Exynos Auto V920 since 2023. Why is it important. Samsung’s Samsung LSI (Large Scale Integration) division is responsible for the design and development of chips and solutions for semiconductors. It is not only responsible for manufacturing Exynos processors, but also ISOCELL image sensors or the 5G modems themselves. Without a detailed shock plan, the data on the table tells us of estimated losses of 1 trillion won in 2024, a result that was partly due to the inability to integrate the processor Exynos 2500 in the Galaxy S25 series. Beyond smartphones, a crucial division for Samsung, fully entering the automotive world is an important step to clean up its accounts. In fact, Samsung’s move goes beyond simply supplying the Exynos Auto. Recently, Harman (Samsung subsidiary) agreed to purchase ZF Friedrichshafen’s ADAS unit to reinforce its presence in advanced assistance systems (cameras, radars, critical computing, etc.). Interior of the BMW 7 Series The software war. The current war in the automotive world is not about the engine, It’s in the software and the screens. It’s getting to that pointthat manufacturers such as Volkswagen have come to declare that “they are not phones, they are cars”, as an argument to reintroduce the haptic buttons that their customers missed so much. The European Union itself has had to take action on the matter, and the new Euro NCAP will be valued very positively the return of physical buttons. Despite this, screens are here to stay.

The plan has always been to destroy the International Space Station in 2030. Someone thinks we can do something else

by

The International Space Station this that falls. It has been orbiting the Earth since 1998 and was completed in 2011. The plan was to retire it in 2024, but the accounts did not work out and, in 2021, the NASA administrator set a definitive date: 2030. The question is whether it will last that long because a few months ago we already said that members of NASA expressed concern about the accumulation of problems technicians who were accelerating the decline of a seriously aging facility. air leaks, cracks in different modulesabsence of spare parts for critical systems and lack of budget to propose a solution It would be assumed that the Different agencies have been putting patches on for years. NASA has already commissioned SpaceX the development of a ship that would tow it to the space graveyard of the Pacific, but… is there no other solution for the 450-ton, $150 billion station? The answer is yes. At least, that’s what Greg Vialle, founder of a startup called Lunexus Space that is committed to recycling the International Space Station, thinks. Turning the International Space Station into a mine In the middle of last year, NASA had clear that he Point Nemoa remote location in the Pacific, 2,700 kilometers from the nearest pile of dirt, would be the station’s cemetery. There was only one thing I could avoid the dismantling: that ROSCOSMOS, the Russian space agency, refused to abandon the ship. Russia soon changed its mind by commenting that its cosmonauts were passing more time repairing equipment than conducting experiments. Come on, no matter how much they wanted to “annoy” NASA at a geopolitically unstable point, it didn’t work out for them. Everything was aimed at the disappearance of the current ISS, but there are those who have something to say. Lunexus Space is a startup focused on the development of industrial infrastructure in low orbit that reuse structures and space junk to facilitate the construction of goods directly in the lower atmosphere. The goal is to develop a kind of circular economy in low orbit by taking advantage of the tons of material already in space, eliminating the need to re-launch them from Earth. In Space Newsthe CEO of the company has developed an article in which he explains his plan to “avoid wasteful expenses.” Vialle affirms that the ISS has 430 tons of high-quality aluminum, titanium and other materials valuable for future space missions. He estimates the value of the material at $1.5 billion, which would be lost to the ocean floor if NASA’s plan goes ahead. And it also points out the almost 1 billion that NASA will spend on the vehicle that tows the station to its resting point. “It is a fiscally irresponsible plan that loses a strategic resource and a golden opportunity.” What he proposes is “a common sense alternative”: converting old infrastructure into raw materials for new construction. Their calculations highlight that launching a kilogram of material into space costs $3,500, but if they take materials from the ISS, the costs would drop entirely. And, faced with the 1,000 million dollars of the plan to sink it, Vialle suggests that Its recycling process could be carried out for about 300 million dollars to which an equivalent government loan would have to be added to launch the necessary infrastructure, appealing to significant savings for taxpayers while preserving valuable resources. American leadership, of course “How can we wait prospect, mine, refine and transport in deep space if we cannot extract the many tons of cataloged and space-grade materials that are already beginning to manage low Earth orbit?” Vialle appeals. But of course, there is a B side to this plan: Strengthen America’s Space Leadership. By receiving the ISS, the CEO believes that the seeds of “a new industry in space led by the United States will be sown, ensuring our economic and strategic leadership over competitors like China.” China too He has been planning his own station for years. And he compares the move to American manufacturing policy to prepare for the Second World War, japanese strategy in the 1970s that established the country as a technological miracle or Taiwan’s position with TSMC and chip manufacturing. His idea is for the United States to invest in resource management technologies in space, something that is taking its first steps and that, if it reaches a solid program, will make “the nation dominate the future of commerce and defense in orbit.” It is evident that Vialle has known what sticks to play in a moment as sensitive as the current one and, although in his letter he urges Congress to influence NASA’s decision to ‘deorbit’ the International Space Station, the space agency has already detailed that, after a session to evaluate the possibility of reusing the main components of the station, they did not receive any proposals of interest from the industry. On the other hand, the European Space Agency already pointed out that recycling in orbit was “a real challenge” and it was not clear whether the resources used to capture and process waste in space would be profitable. Either way, time is of the essence. We will see what happens with the ‘Recycle the ISS’ movement, but there are four years left and, as more and more voices point out, something must be decided because the installation is on its last legs.

The memory of young people is deteriorating at a record pace. Science thinks it knows why

by

The memory problems among youth are beginning to be worrying. This is what a new study scientist published in the magazine Neurology and that tries to answer why this happens and above all the reasons that exist for our youth to begin to be in decline in regards to to your memory. The surprise. What can logically be expected is that with the passage of time and accompanying aging, memory problems begin to appear that anticipate dementia. But in the United States, after analyzing millions of people, they have seen that the population most affected by this ‘mental fog’ is precisely the youth. And the result in this case is very important: self-reported cognitive problems among young adults aged 18 to 39 have almost doubled in the last decade. But it is something that we are not understanding. The study. To reach this conclusion, a total of 4.5 million people who responded to the national survey of the Behavioral Risk Factor Surveillance System (BRFSS) from the CDC and collected between 2013 and 2023. In this way, there was a truly large sample of people to analyze, although limited only to the United States. The results in this case were quite clear: the prevalence of adults reporting a cognitive disability increased from 5.3% in 2013 to 7.4% in 2024. But what was truly interesting came when separating the results by demographics: In young people aged 18 to 39, the rate skyrocketed from 5.1% in 2013 to 9.7% in 2023. This group is, in fact, the driver of the overall increase in the entire population. In those over 70 years of age we saw a decrease in prevalence from 7.3% to 6.6%, when logic tells us that it should increase. Other factors. In order to know the reason for this increase, other factors behind the respondents had to be traced as well. In this case it aimed at the income level: Have low income with less than 35,000 dollars a year left us with a prevalence that increased from 8.8% to 12.6% With high incomes (>$75,000) the rate was much lower, although it also dropped from 1.8% to 3.9%. But the same thing happens with the educational level, where young people who did not even have high school went from 11.1% to 14.3% while those with university degrees increased from 2.1% to 3.6%. And even in order to obtain much more information, they wanted to analyze the prevalence according to the race of young people, where it could also be seen, for example, that Asian adults are the ones who reported the least cognitive problems. Specifically, the data is the following: American Indians/Alaska Natives: continue to have the highest prevalence, rising from 7.5% to 11.2%. Hispanic adults: saw a significant increase from 6.8% to 9.9%. Black adults: The rate rose from 7.3% to 8.2%. White adults: increased from 4.5% to 6.3%. Asian adults: Consistently maintained the lowest rates, going from 3.9% to 4.8%. What is happening? With all the data in hand, it is logical to think about what is happening so that young people increasingly have more cognitive problems. And for researchers there is not only one valid answer, but there are several that are being proposed. The first of them is that there is greater awareness about this problem, and that is why there are more people who raise their hands when presenting it and have no doubts when it comes to seeking help. But there are also other factors such as economic stressors or work problems that seem to be contributing to these trends. All this without forgetting that the greater presence of digital tools may have meant that our memory is not as trained. But all the social and economic factors we face today can also mark an important milestone when it comes to the real burden on our minds. This ‘overload’ can condition the appearance of these highly relevant cognitive symptoms.

We have been thinking for years that, after the midlife crisis, old age is synonymous with happiness. This researcher thinks it’s a hoax

by

We are happy during adolescence and late youth, but as the years go by we become increasingly sadder, more unhappy, more miserable. At some point, in our late 40s to early 50s, we hit rock bottom. And once there everything tends to improve. “It’s statistics,” we said. What we did not suspect was that the statistics could be ‘trick’. Happiness is U-shaped. “Happiness is a slippery slope until we hit the bottom at some undetermined point in middle age. From there, it climbs back to the levels of youth.” That’s what I said a 2008 study than by Blanchflower and Oswald with data from more than half a million people. Over the following years ( here an example from 2017), studied in some detail how firm this U-shaped trend was; Everything seemed to indicate that this was the case. Until Fabian Kratz and Josef Brüdel from the Ludwig Maximalian University of Munich they realized of a small – possible – problem. Wonkblog A fundamental problem. What if happiness steadily decreases with age and what we see in the aggregate graphs is just a statistical effect? Kratz has been studying for years happiness and, as explained in New Scientistis increasingly convinced that the U simply does not exist. Reviewing the scientific literature, the authors found studies that justify a “stability“in happiness throughout the years; a”increase” or progressive descent; a inverted U; a U normal; and a curve like of waves (promotions, relegations). The problem is “that all studies on age and happiness have incurred biases that have distorted their results.” The other form of happiness. By correcting them, Fabian Kratz and Josef Brüdel came to the conclusion that it is true that happiness shows some stability around the last 50, but it does not rise at any time. Kratz and Brüderl (2021) But why? It is important to keep in mind that this work is essentially methodological. But Kratz’s central idea is that previous studies they didn’t realize that “after a certain age, happiness seems to increase only because unhappy people have already died.” The least happy people they tend to die before, which would cause an overrepresentation of the happiest at older ages (literally, as said our colleague Andrés Mohorte, pure survivor bias). According to this theory, “that old popular story” through which retirement would open a window towards a fuller and more satisfying life is just that, a story: a lie. Or, perhaps, a strategy. Because, in short, “there is a lot of evidence about how humans experience a bassoon psychological in middle age” (Blanchflower and Oswald, 2007; Steptoe, Deaton and Stone, 2015; Graham and Pettinato, 2002), but there is very little about the relationship between that downturn – that unhappiness – and quality of life. As we said quite a few years ago“we’re about to see what happens to the millennials when they become unhappy” and maybe that is behind a part generational battles. But facing the future with the certainty that things are going to improve is not the same as facing the future with the certainty that things are going to get worse. The science of happiness has never been so depressing. Image | Garloncio In Xataka | If the question is “where is the secret to happiness,” an expert believes it is hidden in these 15 statements

Walking cats with belt is in fashion. We have asked an expert in feline behavior and is clear about what he thinks

by

If you have Instagram or Tiktok and you like cats, I bet an arm to which videos have come out of Cats that leave the house tied with strap and harness. Some even go on a trip around the world, explore forests, jump, run and They even swimas if they were dogs. How is it possible? Is it advisable to walk the cat? To solve these and other doubts we have spoken with Paula VanascoFeline therapist and president of the association Rescues Borges Blanques. The phenomenon of adventurous cats It began to popularize in the 2010 on Instagram. One of the first was Vladimirthat traveled with its owners in a motorhome Throughout the United States. Also Skattya Maine Coon who was traveling on a sailboat with its owner, who was completely deaf and leaned on the cat to know when ships approached or sent him messages. A search on Tiktok returns to hundreds of results. “Cat harness”, “Adventure Cat”, “Cat Leash Training” … Today, any of these searches in Tiktok or Instagram returns us hundreds of results. Walking to the cat is fashionablebut it is not easy. If not, many of the reels that appear to us would not be tutorials and advice to accustom the cat. And if there is something that has tried to know is that, unlike dogs, cats They don’t like anything to atten. Understanding the nature of cats Paula is part of the team of Feline therapy And in your day to day Treat cats with behavioral problemssome of them caused precisely by these walks. Its positioning is clear: it is not a good idea to put a belt to a cat. “Cats are hypersensitive animals. For them a harness is stressful, so when you put it on the first time, many are thrown to the ground.” In addition, he adds that “to make it safe, it has to go very tight, which still makes it more annoying for the animal.” You have to understand that the nature of cats differs a lot from the dog. They are territorial animals and They feel safe within their territoryit doesn’t matter if that territory is the countryside or a flat in the city. When they leave their comfort zone, they always do it very little by little: “The cat needs to explore the territory at its rhythm, not that you take it wherever you want.” Instead, walking to a dog is more natural because its nature is to move in herd. They are social animals And security is provided by your pack, so when we walk them they feel safe. Image: Amparo Babyloni, Xataka Surely you have seen cats rubbing against the corners of furniture or other objects. It is the way they have of Create a safe space. When they explore, cats are rubbing at different points where They leave pheromones that serve as olfactory references. “This is how they explore the territory feeling safe. If there is any scare they go back, then they leave again … and so on until they have it controlled.” “When we get the cat out of its territory, it adopts a prey behavior. If there is a strong noise you will try to run and if you are tied, you can’t do it.” Nor should we forget that, although cats are predators of small animals, they are also prey to other larger ones. “When we get the cat out of its territory, it adopts a prey behavior. If there is a strong noise you will try to run and if you are tied, you can’t do it,” says Paula. It is not that the cats we see in the Instagram videos are all stressed, Some enjoy those outings, But according to Paula “they are the exception. They are cats that have learned that their environment is that and also have a very balanced character.” Using them since childhood is key because “cats do not develop fear until they have 5 or 6 months,” but insists that this is not a guarantee that it will enjoy it and should never be forced. What we don’t see on Instagram If it is outside its territory and scares, The cat instinct is running and getting safebut what happens if we have it tied? Two things can happen: “Let the harness escape or attack you.” In This video You can see perfectly how the cat tries to flee and when not getting it, he ends up biting its owner. Is what is known as redirected aggressivenessan episode in which the cat has a very violent response, in this case for a clear cause: try to flee and not be able to. If the cat tries to flee being tied, two things can happen: “That the harness escapes or that attacks you” The other scenario is to get rid of the harness and run away (the most common, because we already know that Cats are liquid). Being in a environment“It has no visual or olfactory references and there are not a few cases of cats that end up being lost.” If it is also in the city, the risk that a car is hit or attack a dog is very high. There are people who opt for Take the cat inside a backpack type carrier and walk it in this way. Here it is much more difficult for the cat to flee, but Paula does not recommend it either: “I had a case of a cat that took him inside a backpack. The cat did not show the stress at the time, but when he got home he became aggressive. They were very frustrated to be locked up.” Another problem is that many people who get their cats abroad do not know how to understand The language of cats. “That a cat is still does not mean that it is calm.” In other words, it is not necessary to go crazy like that of the video so that it is assuming stress.

China already thinks about strategies to neutralize Elon Musk’s Starlink satellites. Your plan: submarines and powerful lasers

by

Chinese scientists have developed strategies to neutralize the Starlink Satellite Network of Elon Musk, which Beijing considers a military threat. According to the medium The Independentamong the proposed measures are furtive submarines equipped with spatial lasers, attack satellites with ionic propellants and sabotage of the supply chain. An analysis of 64 academic articles published in Chinese magazines reveals the concern of the Asian country for Spacex’s spatial domain. Why worries so much Starlink. The constellation of satellites carried out by Elon Musk controls two thirds of all active satellites in the world, with more than 8,000 operational units. Its ability to provide fast and cheap connectivity anywhere on the planet, including remote areas, makes it a strategic tool. Chinese researchers They fear that the United States will use it as a military weapon after checking its effectiveness in Ukraine, where facilitated the communications of the Ukrainian army and the control of combat drones. What China poses. Several Chinese researchers and scientists have proposed multiple approaches To counteract Starlink. Engineers of the Popular Liberation Army suggest creating a fleet of spy satellites that follow those of Musk, collecting signals and using corrosive materials to damage their batteries. Other researchers propose optical telescopes to monitor the network, generation of false objectives through Deepfakes and the use of powerful lasers to burn equipment. They have also identified vulnerabilities in the Spacex supply chain, which has more than 140 main suppliers. They will not only be countermeasted. Beijing is not limited to planning countermeasures: it is building its own alternative. In 2021 the Chinese state company created SATNET To develop Guowang, a military megaconstellation that already has 60 operational satellites of the 13,000 planned. In parallel, The Qianfan companysupported by the Shanghai government, has launched 90 satellites of the planned 15,000 and already competes for contracts in Brazil, Kazakhstan, Malaysia and several African countries. The geopolitical context. The Ukraine War marked a turning point in Starlink’s global perception. The conflict showed that the control of satellite communications can tip the balance. What worries China is that a single man like Musk can also interrupt critical services. The medium raises as an example that time in which the tycoon He denied his coverage For a Ukrainian counterattack in Crimea. This dependence on private actors He has not only alarmed Chinabut also to traditional allies of the United States such as the European Union, which invests billions in Your own Iris2 constellation. What comes now. The overwhelming domain of Starlink in space, which already operates in more than 140 countries and only has dead areas in North Korea, Iran and China, has triggered a undercover space race. While Amazon develops her Project Kuiper With just 78 satellites, China accelerate your programs To reduce Musk’s advantage. Interestingly, one of the papers of Chinese researchers simply had the following title: “Be careful with Starlink”. It is clear that space control will be an advantage for armed conflicts and commercial wars that are being released.

Traveling by plane with a monstrous battery sounds great. Until airport safety thinks

by

Travel salts and do fast checkeo: molts, clothing, pajamas, jacket in case it refreshes (which you will end up not using), loaders and loaders The Power Bank of 30,000 mAh with which you can load your mobile and that of all your friends a couple of times. You keep everything, you arrive at the airport and surprise: You can’t pass with such a large external batteryso they requisition and lose it. Indeed, in the same way that we can only carry liquid boats up to 100 milliliters In a transparent plastic bag up to a liter of capacityexternal batteries also have limits. Knowing them will help us not to take an unpleasant surprise as soon as you start the holidays Let’s talk about airplanes. IATA (International Air Transport Association) is the global commercial organization that groups the majority of the world’s airlines. It represents more than 350 airlines in 120 countries (that is, 80% of world air traffic) and among its many tasks is the promotion of safety standards. It is in the 66th edition of the IATA DANGEROUS GOODS REGULATIONS where the limits of lithium and ion-lithium batteries are collected (PDF). Image | Xataka The limits. According to the IATA, we can carry in the hand luggage, and always in the hand luggage, not in the winery, a maximum two external batteries of up to 100 Whing each. The same is secreted by EASA (European Aviation Safety Agency) (PDF). IATA terminology, however, is something confusing because it considers the Power Banks as spare/loose batteries, and of those we can take up to 20. However, if they are non -spillable batteries, they must be 12V or less, 100 whi or less and the limit is two units per person. If it is a replacement battery of between 100 and 160 WH, we can take up to two that the operator approves it and if it is greater than 160 WH, we most likely cannot transport it, as the EASA exposes. So, and to go on insurance: Maximum capacity: 100 Wh Maximum units per person: two Power Banks. Image | Gomi Forgive, Wh? In the Tech world we are accustomed to talking about the ability of a battery in terms of MAH (milliamp tell us about (watts time). If the brand of our Power Bank gives us the data, better than better. If not, we can do the MAH> WH conversion with this formula: (mAh) x (v) / 1000 = Wh Power Bank usually have a 3.7 volt voltage, so in the case of an external 20,000 mAh battery we would be talking about 74 Wh. That leads us to the following conclusion: if we want to carry the Power Bank on an airplane, the maximum theoretical capacity must be, at most, 27,000 mAh, although it may be tightening the rope too much. With a battery of 20-25,000 mAh we should go more than served, so, again, to go on insurance on an plane: Maximum capacity: 20,000-25,000 mAh. Maximum units per person: two Power Banks. Image | Gomi But one thing. This is a general rule and airlines usually accept it or adapt it, but we have doubts the ideal is to speak with the operator and comment our particular case. It is also possible that There are concrete standards depending on the country or the airline. For example, Hong Kong’s laws They prohibit loading the Power Banks using the USB take of the seats or loading devices with the external battery during the flight. South Korean operators force To take the battery at all times with us (not in a backpack, not in the upper trunk, with us) and companies like China Airlines and Singapore Airlines They prohibit The use of them during the flight. China’s case is particular. The Civil Aviation Administration of China (CAAC) issued an urgent notice whereby, as of June 28, 2025, passengers are prohibited from climbing the plane With batteries without the 3C certification (CCC). This is a mandatory security brand, similar to the European EC, which guarantees the quality and safety of Chinese products and that applies to both those imported and those manufactured in China. The thing is that, for the moment, it only applies to domestic flights. And in the trains? Nor in the Renfe conditions nor on the Adif website any mention is made to external batteries. Renfe, in fact, considers dangerous objects to firearms, white weapons, sports and sharp work instruments. Weapons could behave if we carry the relevant license or accreditations, as well as ammunition. What we cannot carry are sharp objects such as knives or stabs, paint ball guns and explosive, flammable, chemical or toxic substances. They do not specify anything about external batteries. They do not do it either Iro and Ouigowhich have similar restrictions and in no case refer to external batteries. Anyway, from Xataka we have contacted the three operators to get out of doubt and update in the case of receiving an answer. Image | Tonny Zhong

If something did not need the Ukraine War it was to enliven the conflict in an occupied nuclear power plant. Russia thinks different

by

The paradox of the largest nuclear power plant in Europe is that it has been closed for three years and everyone wants to “open.” Without going far, the United States was the last nation to hint that it would be delighted to restart her. The problem is that it is in Ukraine, although Taken by Russiaand in the middle of a war whose end does not stick. Moscow knows that he has an energy pressure tool, but some satellite images have revealed much more. The space betrays. The story took this week The New York Times. Through new satellite images analyzed by Greenpeace and verified by the American environment, it has been revealed that Russia is building more than 80 kilometers of electric lines in the south busy of Ukraine with the aim of connecting the Zaporiyia nuclear plant to its own energy network. Covert reopening. This maneuver, until now without Russian official confirmation, represents the clearest signal until the intention of Moscow’s intention to reactivate and exploit the largest central in Europe, forcibly in the first bars of the invasion. Although its six reactors were gradually turned off (the last in 2023) for security reasons and due to nearby fightingRussia seems determined to return it to operationchallenging the warnings of international experts that consider that operating it under these conditions would be a nuclear risk first order. The Russian Plan seeks surround the current damage In the old 750 kilowol lines that connected the central with the Ukrainian network, two of which are going through areas under Kyiv control, and two others that have been useless or deteriorated by the war. Unprecedented use. If specified, this would be the First time in history in that a power at war restarts and uses an occupied nuclear plant for its own energy benefit. Russia, through the state Rosatom, has openly shown Your ambition: its general director He said recently that the dream of reactivating Zaporiyia is still alive and that there is already a technical plan to return the plant to full capacity. The Russian intention does not seem to maintain territorial control of the complex, but to integrate it directly into the national electricity network, possibly and According to the Timesconnecting it with the Russian region of Rostov, which would require even more infrastructure. As we said at the beginning, the United States proposed a peace plan that included the return of the plant to Ukraine under international management (specifically American), In an attempt to avoid its use as a geopolitical tool. Russia He rejected sharply said option. Various risks. No doubt, we don’t talk about simply pressing the “ignition” button. In fact, the possibility of reactivating the central has awakened alarms Among nuclear experts. Since his shot, much of the Ukrainian technical staff has fled, leaving the plant No qualified operators. In addition, the Kajovka dam hole months ago (widely attributed to Russia), it eliminated the main source of water from the reactor refrigeration system and spent fuel, raising thermal and fusion risks in case of a failure. For its part, the Minister of Energy of Ukraine He warned that any Russian unilateral attempt to restart reactors could have unpredictable consequences. To all this is added The possibility of sabotage, military attacks or operational failures in a plant already located in an active combat zone. The consequences of a nuclear escape would not be limited to the region: the impact on the environment, human health and the energy stability of Europe would be unpredictable (and possibly devastating). A high voltage piece. As we have coming countingthe status of the Zaporiyia plant has become a power sheet in the peace negotiations. While Russia progresses (slowly) in her Technical reconnectionThe United States and its allies press to include their status in the terms of any future solution. The satellite images Recent, which reveal transmission lines advancing near the town of Shevchenko and towards a key substation linked to the complex, confirm that Moscow not only wants to retain control, but to turn the plant into a Active source of energy for your network. If you want also, snapshots from space reveal a deeper strategy: to consolidate the economic and energy control of the territories occupied as part of a Possible post -stroke. However, any attempt by Moscow to reactivate the plant without international consensus not only defies the rules of war law, but also brings us an unpublished threshold of nuclear insecurity.
