“Life begins on the other side of despair”

It doesn’t matter where you are from, how old you are, what you do or what you entertain yourself with. It almost doesn’t matter how you think. Most likely the word “despair” causes you an automatic rejection. Normal, right? In life there are good sensations, others that are debatable, and there are those that are undesirable no matter how you look at them. Despair, anguish, is part of the latter because no one in their right mind would choose despair over hope. No? If we are clear about the above, why the hell in 1943 did the philosopher Jean-Paul Sartreone of the most prestigious minds of the 20th century, had Orestes pronounce the next words in his theater work The flies? “Human life begins on the other side of despair.” The question is timely because, unlike what happens in most literary works, here it does not seem that it is the character who speaks to us. If we take into account Sartre’s philosophy, in this case it is not unreasonable to think that it’s himself who moves Orestes’ lips to express his opinion. Did Sartre really believe that ‘despair’ is the door to life? Isn’t that a discouraging and gloomy panorama? Sartre and existentialism Before talking about how Sartre thought, it is worth knowing who Sartre was, one of the lighthouses of Western philosophy of the 20th century. Thinker, novelist, playwright, critic and political activist, Jean-Paul Sartre (1905-1980) is remembered above all for being one of the great exponents of existentialism. Without it it is difficult to understand the intellectual panorama of 20th century Europe and figures of the stature of Soren Kierkegaard, Lev Chestov, Albert Camus either Martin Heidegger. Although its seams are wide and there are important differences between authors, basically existentialism as conceived by Sartre (atheistic existentialism) is based on a premise: humans are born without a predefined purpose. We are not toasters, cars or TVs, objects created based on a concept and with a specific purpose. Nor are we the work of a superior “craftsman.” Unlike what happens with what we make as men, objects in which the “essence” is prior to the “existence”, in our case it is the existence that precedes the essence. What does that mean? “That man begins by existing, finds himself, emerges in the world, and then defines himself,” the French thinker clarifies in one of his key works, Existentialism is a humanism. “Man, as the existentialist conceives him, if he is not definable, it is because he begins by being nothing. He will only be later, and he will be as he has been made. Thus, then, there is no human nature, because there is no God to conceive it,” Sartre continuesand insists: “Man is nothing other than what he makes himself”, a creature “condemned to be free.” We have not chosen to be here. We have not created ourselves. And yet we are responsible for everything we do. It is not lost on Sartre that this scenario can lead to “anguish”, a feeling of helplessness and despair. He is not the only philosopher who addresses the topic (Heidegger and Kierkegaard also did), although it is true that the Frenchman’s work helps us understand how important sensation is. for him Anguish is nothing other than “the awareness of being one’s own future in the way of not being one”, an overwhelming feeling in the face of the range of possibilities that are open to man, radical freedom and lack of answers. This approach leaves behind an idea that is as fascinating as it is overwhelming: man is born with a huge challenge aheadthe challenge of living authentically, assuming your freedom, choosing your course, giving meaning to yourself and making decisions that will have consequences for your entire environment. There is no destination. There are no excuses. It depends on us. “Man will only be afterwards and will be as he has been made. It is nothing other than what he makes himself. If it precedes the essence, man is responsible for what he is”, warns us. “(Fyodor) Dostoyevsky writes: ‘If God did not exist, everything would be permitted.’ This is the starting point of existentialism. In fact, everything is permitted if God does not exist and, consequently, man is abandoned, because he finds neither in himself nor outside himself a possibility of clinging. “First of all, it finds no excuses. If existence precedes essence, the reference to a given and fixed human nature can never be explained. In other words, there is no determinism, man is free, freedom.” “The first step of existentialism is to put every man in possession of what he is and to place upon him the total responsibility for his existence. And when we say that man is responsible for himself, we do not mean that man is responsible for his strict individuality, but that he is responsible for all men,” Sartre continues. Understanding this enormous responsibility and all its implications generates anxiety, but that has no why be negative. The reason? As Orestes proclaims in his dialogue of the The flies This hopelessness does not have to be frustrating or plunge us into inaction. On the contrary. “It is the very condition of their action because this means that they face a plurality of possibilities and, when they choose one, they realize that it only has value because it has been chosen,” illustrates the philosopher, drawing a parallel with the anguish that a general feels when he decides something that will affect the lives of his soldiers. “existentialism is an optimism, a doctrine of action,” claims Sartre, who ends his essay with a warning: those who use despair to attack it do so by “confusing their own feeling with ours.” It may sound like an old-fashioned lesson (Sartre died in 1980), but his words resonate strongly in an era in which we live hyperconnected, among related ephemera in which the need to search for meaning, identity and authenticity is especially felt.

that is on the hidden side of the Moon

Just as it happens when you want to see a shower of stars or meteorites, to observe the universe well you have to flee from civilization. If you are looking for an elevated place, all the better. That explains why there are large observatories in the Atacama desert in Chile, in the Roque de los Muchachos from La Palma or the Square Kilometer Array in Australia and South Africa: deserts, volcanic peaks or remote plains are ideal candidates. That on Earth. Astronomer Jack Burns, whose career began in the late 1970s in the Very Large Array of New Mexicohas spent his entire professional life defending that the next big jump is the Moon. Time is proving him right. The Earth is not enough. Clear skies, a dry atmosphere (humidity distorts signals), and getting away from humanity’s electromagnetic noise are essential to having a good observatory. But as Burns has seen firsthand, even in an environment as privileged as that of the VLA, there are insurmountable limits to knowing more about the origin of the universe for two reasons: Earth’s ionosphere blocks much of that low-frequency spectrum. There is still electromagnetic pollution from humanity, for example electrical, telecommunications, radar infrastructures… that mask the signal. The problem of signs of the beginning of the universe. The most abundant element in the universe is neutral hydrogen, but while in the laboratory it emits at 21 centimeters of wavelength, if the signal arrives from the dark ages traveling through the universe, it reaches the Earth stretched to a range that cannot be heard well. From Earth. These radio signals from the cosmic dark ages, a period of between 200 and 400 million years that It started “only” 380,000 years after the Big Bangare really weak and reach frequencies below 50 MHz (very low), so it is difficult to capture them from Earth. Hajor. Wikimedia CC BY-SA 3.0 The solution is on the far side of the moon. The far side of the moon is probably one of the quietest places in the inner Solar system as the mass of the satellite serves as a kind of natural shield that blocks terrestrial and solar signals. When it’s night on the moon (a night that can last up to 14 Earth days), it is possible to achieve almost complete electromagnetic silence: without direct solar radiation and without interference from the Earth. Ideal for listening to the cosmos. Why is it important. Hearing about the dark cosmic age sounds abstract, but being able to observe them would be useful to better specify the models that explain how the first stars and galaxies were formed, not to mention the advances it would allow in the observation of dark matter, dark energy or gravitational waves. In addition, it opens the doors for the moon to become a permanent scientific platform for humanity. This is the LuSEE-Night radio telescope. It’s time for presentations: Lunar Surface Electromagnetics Experiment – Night It is the radio telescope designed to take advantage of that silence. It operates in a range from 0.1 to 50 MHz with the goal of mapping the first low-frequency sky and potentially capturing those first signs of the dark ages. Technically, it had to overcome contradictory demands: it was required to have high sensitivity to detect the weakest signals and, at the same time, high resistance to deal with a hostile lunar environment with large thermal variations. This minimizes its own noise so as not to dirty the listening and with the ability to communicate with the Earth. A winding path. The program has been full of disappointments: in 2024, the first American lunar landing in 50 years, the Odysseus module, landed poorly and broke a leg. It only had time to transmit two hours of data, enough time to at least confirm that the hardware was working. In March 2025, Firefly’s Blue Ghost 1 achieved the first successful private lunar landing and now LuSEE-Night will travel on its successor, Blue Ghost 2, which will land on the far side of the moon without anyone on Earth being able to see it. What comes next. If LuSEE-Night is successful, the roadmap is ambitious: develop FarViewa colossal lunar interferometer on a larger scale that would allow the study of the dark ages with a precision hitherto impossible. The project would begin assembly in the 2030s and would have initial funding from NASA. In Xataka | The hidden side of the Moon is no longer a mystery.

In 1986 a man parked on the wrong side of the gas station. That day he solved an embarrassing problem for all drivers

The history of innovation It’s full of big names and epic breakupsbut also of silent advances born from minimal errors, from everyday mistakes that anyone could have made. Sometimes, a small mistake reveals a problem so common that no one had thought of it or knew how to formulate it, and it is enough to look at it differently to find a solution that ends up benefiting millions of people without it being barely noticed. In this case, one man saved millions of drivers from embarrassment. A universal problem. Maybe his name doesn’t sound familiar to you, but the story of Jim Moylan It is more important than it seems. The story begins with a scene as trivial as it is recognizable: a Ford engineer (Moylan) soaked by the rain, standing at a gas station, realizing that he has parked in the wrong side of the pump. Where anyone would have felt frustration or perhaps some embarrassment, he saw an everyday problem that could be solved elegantly, cheaply and definitively, and in a matter of minutes. wrote a memorandum proposing a small symbol on the instrument panel to indicate which side the tank was on, a simple idea born from personal experience and the conviction that eliminating that doubt would save time, inconvenience and, yes, small humiliations for millions of drivers. The path to a great idea. Moylan was not a media figure or a senior manager, but an engineer with a long and discreet career within the all-powerful Ford Motor Company, a man, yes, professionally obsessed. with instrument panels and with making them as clear and useful as possible. Thus, after sending his original proposal in 1986, the man did not think about it again, but the company did: the symbol he had scribbled on a page quickly went into development, it was approved without much resistance. and ended up integrating in the first models of the late eighties, demonstrating that in large organizations there was still room for a good idea, no matter how small and coming from whoever it was, to cross the hierarchy and become a reality. From Thunderbird to the entire world. Months passed until the first public appearance of the arrow came, an almost imperceptible moment, hidden in the instrument panel of a Ford Thunderbird 1989. It didn’t matter, its power lay precisely in that simplicity. It was so obvious and useful that the competition It didn’t take him long to copy itand in a very short time it went from being an internal Ford solution to becoming a de facto standard in the global automobile industry, and it did so to the point that today it appears in practically any car in the world, including electric ones, where it points to the side of the charging port with the same unbeatable logic. The inventor without a patent (or ego). Unlike other innovators, Moylan He never patented his idea nor did he ask for financial compensation or public recognition, content simply to see how his arrow worked and helped people. For decades, millions of drivers benefited from his invention without even knowing his name, while he silently watched as that little “walk of shame” at gas stations disappeared, getting closer sometimes to strangers to explain the usefulness of the symbol, but without ever mentioning that it had been his doing. Late recognition. I remembered a few weeks ago the wall street journal which was not until many years later, thanks to a chance investigation from a podcast and to the rescue of internal files, when Jim Moylan’s name came to light and he was publicly recognized as the author of one of the most discreet and universal innovations in the automobile. The man died without having sought famebut he left a legacy that lives on every time someone stops at a pump and, with a simple glance at the instrument panel, knows exactly where to stand, reminding us that sometimes true genius lies in solving the obvious in the simplest way possible.

Tesla is pivoting to turn its cars into a side business. The reason: their income falls by 61%

The Tesla Model S and Model X are incredible cars. Get them while they’re still available! With these phrases, Elon Musk, CEO of Tesla, has accompanied the company’s announcement in X in which they point out that during the next quarter they will reduce their production of the Tesla Model S and Model To its credit, the company will produce Optimus robots. by surprise. It was known that Elon Musk has been pushing for some time for Tesla to increase its investments in artificial intelligence and robots, either in humanoid form like Optimus or through its robotaxis for autonomous driving. But what we did not expect is that this bet would displace two of its most iconic models. And the company will stop producing its Tesla Model S, its first sedan, and the Model X, its first SUV, in Freemont (California) to make way for the production of Optimus robots. The company closes a chapter by recognizing that “Tesla would not be what it is today” without these cars. In Xataka Tesla wanted to make 20 million cars in 2030. The reality in 2025 is that Tesla has crashed and BYD is already leading A paradigm shift. The decision to invest in this factory to increase robot production is more than just a redistribution of its efforts, it is confirmation of a change in strategy in the company. Musk seeks invest $2 billion in xAIthe company dedicated exclusively to artificial intelligence. Intertwining your companies is one of the obsessions from the CEO of Tesla so that some feed each other. xAI is key to power and improve Grok which, in turn, is already included in Tesla vehicles as an artificial intelligence assistant. At the same time, xAI is also decisive for the functioning of its robotaxisthe cabin without wheels or steering wheel that Tesla wants to put on the street to offer a completely autonomous taxi service. In Xataka Tesla can’t wait for us to take our hands off the wheel. We have tried it and we have opinions More than complicated numbers. Optimus has left many doubts and Musk himself has confirmed that he expects a slow deployment. However, dedicating a plant that only manufactured a handful of cars is not only confirmation that the company does not care in the least about killing a product if it understands that it is not profitable or that its future is much less interesting than a new bet. Changing the use of the factory is also a necessity. And the numbers presented by Tesla are something much more than complicated: Net profit has gone from 7.1 billion to 3.8 billion dollars, 45% less. In the last quarter, turnover has fallen from $2.1 billion last year to $840 million. It is a drop of 61%. The company has delivered 1.64 million cars in 2025 in what is its second year reducing its sales. In the United States the drop in sales is 7%, according to Cox Automotive, reported in The New York Times.  In the same period, it is estimated that BYD has sold 2.25 million cars Purely electric. In Xataka The Tesla Cybertruck is such a sales failure that Elon Musk has only found one solution: buy them from himself Loss of identity. The Tesla Model S and Model X have become residual cars for the company since the Model 3 and Model Y occupied the bulk of sales. Both are very expensive cars that cost around or exceed 100,000 euros. Both the saloon and the SUV served the brand to boost your image and personality as unique cars. Over the years, that has been lost. And the huge screens that previously surprised now do not stand out in a market that has turned to trying turn the cabin into a multimedia centerespecially in China. Your own assembly line has been forced to keep its design unchangedwhich has made them lose freshness. The popularization of its Tesla Model 3 and Model Y has popularized access to the company, making them lose part of that desirable car aura. {“videoId”:”x9tnvi4″,”autoplay”:false,”title”:”Why YOUR NEXT CAR WILL SURELY BE CHINESE”, “tag”:”Webedia-prod”, “duration”:”614″} A cut production. The decline in sales has led to declining production of both models. To give us an idea, nothing is better than the data provided by the company itself: 2022: 71,777 units produced and 66,705 deliveries 2023: 70,826 units produced and 68,874 deliveries 2024: 94,105 units produced and 85,133 deliveries* 2025: 53,900 units produced and 50,850 deliveries* Starting in 2024, Tesla accounts for the production and deliveries of the Tesla Model S, Model X and Cybertruck in the same item. That’s whyCybertruck sales are estimates outside of Tesla The Tesla Model 3 and Model Y Standard confirms a story. The story of what I want and I can’t of Tesla’s 25,000 euro car In Xataka The Tesla Model 3 and Model Y Standard confirms a story. The story of what I want and I can’t of Tesla’s 25,000 euro carThe limits . Tesla is in a stagnant situation with its electric cars. The company stepped on the accelerator in 2024 to remain the best-selling electric car brand in the world and improve the previous year’s data. But it did not succeed, going from 1.85 million cars produced and 1.81 million cars delivered in 2023 to 1.77 million units produced and 1.79 million cars deliveredin 2024 . Year in which, in addition, They increased their range with the Cybertruck which started at a very good pace. The company, therefore, needs to kill some very expensive cars that are barely generating a positive impact on its accounts no matter how high the profit margin obtained with each unit. To begin with, because the company needs a boost from its investors, who seem to support these decisions. And, second, because we have to see if the company has not already peaked in its vehicle sales. At leastwith its particular way of producing cars with huge presses that are only profitable by manufacturing millions and … Read more

We have accepted that sport is “medicine” for the body. Now science is discovering its side effects

Physical exercise can be prescribed as a drug in doctors’ offices, even though it is not packaged in a simple pill that we take. This is because the evidence behind it has made it more than clear that playing sports can prevent a large number of chronic diseasesI know even have a very good old age. But behind all this, too There is a negative part behind doing physical exercise. Its side effects. If we accept exercise as a drugwe must also accept that every drug has a leaflet, specific doses and of course some adverse effects. That is why as a society we have the problem of having begun to sell the fact of “exercising” in a generic way, ignoring the fine print that this task has, as recognized by the Spanish Heart Foundation itself. And it has a very simple solution: personalizing physical exercises per patient. The problem of metaphor. The slogan “exercise as medicine” is undoubtedly an excellent marketing campaign within the world of public health, but for science there are several important flaws. As different scientific studies point out, exercise does not act like a classic drugsince it does not have a predictable response in a patient as if it occurs as a pill. This forces us to always think that the effect can be very different for each person. In this way, by calling exercise a drug we can make invisible the diversity of individual responses. And there is no universal “squat pill”, since doing this exercise in a specific person can be very beneficial, but in another it can be be the origin of a pathology due to overload. And all because we throw ourselves into exercise without planning how to do it, since we find it very easy to pick up some weights and start building biceps. The damage numbers. We often hear that it is a great danger to stay sitting on the couch, and it is true because they are many diseases related to a sedentary lifestyle. But according to different studies done in the United States, people who meet or exceed the recommendations for moderate or vigorous exercise They have a 44 to 66% chance of developing musculoskeletal injuries. than subjects who remain inactive. In addition to this, although cardiovascular health improves with physical exercise because the heart reduces its heart rate, for example, the “maintenance cost” of the physical body increases dramatically with the amount of exercise done. A question of biases. Without a doubt, this is one of the most critical points that scientific literature reveals regarding the lack of transparency in clinical trials related to exercise. This is something that was seen in an analysis that included 103 trials on knee osteoarthritis, where it was found that 6% of the participants suffered direct damage from this exercise. But the most worrying thing is not the number, but the low information: many patients who abandon studies due to pain or discomfort are not classified as “victims of adverse effects”, which generates an artificially high perception of safety. This problem is repeated in oncology, where the motto “exercise is medicine in oncology” live with non-trivial adverse events which have forced us to propose much stricter monitoring systems to protect patients. We pass each other sometimes. The underlying problem in this case is undoubtedly recommending intensive or complex programs without a clear benefit/harm relationship compared to an alternative that is much simpler. But, on the other hand, we also fall into the phenomenon of “quaternary prevention” making medicine focus on avoiding harm from its own interventions. by overmedicalizingnullifying the benefits of physical exercise. The necessary consensus. In this way, the authors who popularized the concept of ‘exercise as medicine’ explicitly recognize that exercise is not without risks. Even the WHO itself In its guides it maintains that inactivity is the greatest population risk, but there is fine print that must be taken into account: Exercise should be ‘prescribed’ starting with a low intensity, and not opt ​​for maximum intensity from the first day. This causes a person who has spent years on a couch to begin to carry a lot of weight, for example, and end up injured. Pain is not always bad, and the patient must be educated so that they see that fatigue from the gym does not have to be medicalized with pills. Patients with cardiac risk must be evaluated to prevent uncontrolled exercise from aggravating the situation. Be supervised. The conclusion in this case is that exercise is obviously necessary and without a doubt it is one of the practices that can prevent the appearance of many diseases. But we always have to be aware of what we do. Loading the body with a large amount of exercise from minute 0 can cause significant injuries or the aggravation of diseases that are already present. In this way, the possibility of being in a gym with trainers who can advise on the progression curve that should be followed can be an interesting idea to have the benefit of exercise without the consequences of doing it aggressively.

Some people believe that sleeping on your side or stomach creates “sleep wrinkles” on your face. It’s exactly the opposite

The Internet is full of golden rules for have ‘eternal youth’this being the holy grail that many would like to have in their hands right now. Among these pieces of advice, there are several that can be quite annoying, such as that you should not sleep leaning on the side that is wrinkled. But… how true is this? The benefits of sleeping well. The sleeping position is essential to have a good rest. Because sleeping on your stomach is not the same as sleeping on your left side. In the first case, the cervical spine can suffer a lot and in the second the hated gastric reflux. can be seen reduced. But now it comes into play that sleeping on one side or the other can cause more wrinkles on the face due to the hated gravity that generates a mechanical effect that causes the face to fall and wrinkles to appear. But science disagrees on this one and puts the blame more on biology with cortisol and collagen. The myth of ‘Sleep Wrinkles’. The theory seems logical: if you spend 8 hours squishing your face into a pillow, that mechanical compression should leave a mark. There is often talk of “sleep wrinkles” (sleep wrinkles), which, unlike expression lines, caused by smiling or frowning, would be caused by having your face against the pillow. It is something that some experts defend like those of The Aesthetic Society, which suggest that sleeping on your stomach or side favors the appearance of vertical lines due to this chronic pressure. Other opinions. The clinical evidence It is quite limited in this casesince many of the statements that defend this myth come from the field of cosmetic surgery and with very limited groups of people. There are even articles that suggest that there is no clear relationship between sleeping in a certain way and having more wrinkles. The consensus right now is that sleeping on your back could theoretically reduce the formation of compression lines. But obsessing over this is not the best, since if having this position is uncomfortable and the quality of sleep decreases, then the biological weight it will entail will have a great impact on wrinkles. The real threat. This is where science stops being speculative and becomes blunt. If there is something that ages your skin, it is not the pillow, It’s sleep deprivation. When you get little sleep, the body enters a state of physiological stress, raising levels of the hated cortisol, the stress hormone. And elevated cortisol is the great enemy of our skin’s youth. This is because it can inhibit the cells that make collagen (the scaffolding of the skin), making the skin less elastic and increases metalloproteinases. This word, so long, is nothing more than an enzyme that breaks down that fundamental collagen that we have in our skin and that keeps it firm. If we do not produce it or destroy it, the wrinkles will appear there. With data. A key clinical study presented in ScienceDaily showed strong results: People with chronic poor sleep quality showed clinical signs of accelerated aging with fine wrinkles, uneven pigmentation, and sagging. But the most important thing is that if UV radiation from sunlight was also added to all these factors, the skin’s recovery would get worse. And this is where the need to have sun protection when going outside came in.

wells, drought and the hidden side of the avocado

Avocado is undoubtedly a very delicious food and also in high demand for its good macros, which has led to an increase in its production. This proliferation in its cultivation seems to bring good news for our land (especially because it sells well), but on the Costa del Sol and the Tropical Coast of Malaga and Granada the great environmental impacts are already seen which is generating such as the plowing of the slopes and a large water consumption that aggravates the drought already typical of southern Spain. A great consumption. To put figures, More than 20,000 hectares are now dedicated to avocados in these provinceswith some 5,000 hectares converted from dry land to irrigated land, with dubious legality behind it, which has also caused the appearance up to 250 illegal wells in 2023. This expansion, which represents 30% of the Andalusian avocado area (about 9,400 hectares in total), has replaced traditional crops with hypertensive tropical crops despite the climate crisis. All to opt for a crop that can undoubtedly give a great economic return. Environmentalism. A recent complaint made through Along with this complaint, which points to the serious environmental problems that are being experienced, different images are shown that undoubtedly speak for themselves to understand how this crop is affecting the geography. Publication in X by Santiago M. Barajas | Via X What we are seeing is not just agriculture; It is an industrial transformation of the landscape that is pushing the water and geological resources of Malaga and Granada to the limit. This is how avocado and mango have gone from being “green gold” to becoming an environmental time bomb. Destruction engineering. Traditionally, agriculture in these areas was adapted to the natural orography of the land. But now, the model that has been imposed, driven by the very high profitability of the tropical fruit, does the opposite: adapt the orography to the crop by force. According to Ecologists in Action and confirm various edaphic studiesthe implementation of these crops requires heavy machinery to break slopes. The process eliminates the original vegetation cover to create artificial terraces. The result? A severe degradation of the soil in its surface horizons. A problem with storms. With this degradation, what is caused is the elimination of natural vegetation, which produces a “sealing” of the soil and consequently the appearance of cracks that nullify its biological functions. The problem arises when torrential rains appear (increasingly more frequent in the Mediterranean), which causes the water to not filter and run away, dragging nutrients and causing massive erosion. This is something that translates into the use of more fertilizers by farmers, which end up contaminating the subsoil. In short, we are facing a vicious cycle of chemical and physical degradation. An infinite thirst. The avocado is a fruit that fits perfectly in the rainforest, but has now been transplanted in an area with a semi-arid Mediterranean climate. An ideal place for traditional dryland crops such as olive or almond trees that can survive on what falls from the sky. But avocado or mango in a hypertensive model demand about 7,500 cubic meters of water per hectare per year. These demands Added to the large number of plantations that exist, as we have commented previously, it leads to great water tension that we have seen reflected in the La Viñuela reservoir, which has reached only 7% of its capacity in 2023, and which has reached La Axarquía in Malaga. to a critical situation. And this deficit is not solved with rain, but with drilling machines that open wells in the area. In this way, the direct consequence is clear: overexploitation of aquifers and their salinization due to marine intrusion. An escalated problem. This avocado bubble does not stop increasing in our country. Given the collapse that has been experienced in Malagathe model has been replicated in Cádiz, Hueva or Murcia, which in the end are regions that already suffer their own water stress due to not receiving much rainfall throughout the year. But not only has he been emigrating from the provinces, but he has also escalated to the judicial field, where the prosecution points it is already being investigated a possible environmental crime with damage to the public water domain valued at 10 million euros and the illegal theft of up to 26 cubic hectometers of water. And in many of these regions citizens have had to suffer supply cuts due to this shortage, while this agricultural model continued to demand A solution. What is proposed In this case it is the ordered de-escalation of these crops. To achieve this, the goal is to stop new irrigation talks and close illegal wells. The problem is that it faces a very important leg of the economy of some of these provinces, against the change in the landscapes of the region. In Xataka | Andalusia has become a hostile land for the avocado. So an unexpected region is taking over: Galicia

Convenience stores were an emblem of Japan. Until the demographic crisis has revealed the dark side of opening 24 hours

The stores japanese convenienceknown as konbini, are not simple shops where you buy fast food or basic products, they are a deep part of the social fabric of the country. Its success is measured not only in numbers (more than 55,000 establishments spread across the 47 prefectures) but in the way in which they accompany daily life: they allow you to pay bills, send packages, print documents, buy tickets for shows, resolve unforeseen events, take refuge in case of emergency or simply take a break in them. And now that the country doesn’t stop agingthe stores are mortally wounded. The konbini. Let’s think that, in urban neighborhoods, rural towns or isolated coastal areas, these establishments have become the minimum infrastructure indispensable where there used to be post offices, banks or small family businesses that have now disappeared. The store, therefore, is not just a business: it is a safe space, open and available 24 hours a day, an emotional and logistical support point that has shaped the Japanese daily rhythm and has captivated even to millions of touristswho find in these establishments a mix of efficiency, warmth and aesthetic thoroughness that is difficult to replicate. Efficiency and expansion. I remembered the new york times in summer that the development of the Japanese konbini has been the result of an evolution of decades. Since 7-Eleven opened your first store In Japan in 1974, the combination of non-stop hours, quality fresh food (onigiri, bentō, noodles, seasonal desserts) and integrated services made the model a unique phenomenon. For many residents, these stores are literally the closest store, the most accessible ATM, the place to go when something is missing or something happens. The associated image is one of precision: perfectly organized shelves, impeccable coffee machines, attentive employees, continually renewed food and a sense of total availability. From Japan to the world. This internal success was projected outwards, so that 7-Eleven, today Japanese owned, is the largest retail chain on the planet, and global expansion plans aim mainly to North America. The konbini became an exportable image of Japan: efficient, friendly, reliable. The hidden reverse. But not everything shined the same. one piece from the Financial Times has revealed that behind that facade of functional perfection A franchise system is under increasingly intense tensions. Japan agesthe active population is decreasing and small businesses are experiencing increasing difficulties to hire staff. The model requires stores open 24 hours a day, seven days a week, and the pressure not to close falls squarely on the owners. He Akiko’s case and her husband, a 7-Eleven manager who worked without a day’s rest for six months until dying by suicide, starkly revealed the human price of this silent perfection. And more. It was not an isolated case: a labor inspection recognized the relationship between death and overwork, but the root of the problem is structural. Franchisees must deliver between 40% and 70% of gross profit to the parent company, which reduces their margin and exposes them to absorbing personnel, overtime and unforeseen charges. Visible efficiency therefore has an invisible cost. The crisis of the model. Faced with the problem, the chains 7-Eleven, FamilyMart and Lawson have tried make schedules more flexibleintroduce automatic checkouts, ordering systems assisted by AI and robots cleaning to reduce the need for labor. But none of these measures solve the main equation: fewer available workers and more opening hours supported by fewer people. Domestic consumption is also not growing as before, which limits the owners’ ability to increase payrolls. As minimum wages rise, margins narrow even more. many managers they work for free for dozens of hours to keep their stores open. Some they confess that, in the current state, closing would be a more rational option than continuing to operate. The fragility of the system thus becomes visible: if there are no new franchisees willing to take over, the model can collapse. Adaptation or goodbye. The response of the companies points towards a profound transformation of the model. 7-Eleven study contracts renewed from 2027, possibly moving towards the “mega-franchise” model, where the same owner manages multiple stores and distributes human resources between them. However, this implies a concentration of the business and could further displace the small independent owners who historically defined the konbini as a community space. The central question is whether the konbini will continue to be a connected capillary network to the territory or whether it will become a centralized corporate system, more profitable but less close. The great dilemma. If you will, the konbini was born as proximity symbol and frictionless service, and became part of emotional memory from Japan: open places when everything else is closed, spaces where the daily routine has a friendly pause. But that same ideal has been held for decades by people whose efforts they have become invisible beneath the surface of efficiency. Today, the system faces a limit that is not technological, but human. The future of the konbini will depend on whether Japan manages to rebalance the contract between the community, the company and those who keep the doors open at any time, 365 days a year. If it manages to adapt without sacrificing those who support it, it will continue to be an intimate and essential institution. If not, it could become the emblem of a society that knew how to take care of every detail… except for the people who made it possible. Image | Pexels, Japanexperterna, Shankar S.

August has been an extremely warm month in Spain. That has had a side effect: make us older

This summer has left repeated scenes: empty squares at the time of the nap, nights in the heat and a Mediterranean turned into a pressure pot. Spain has suffered suffocating days They will go to statistics, but the most serious is not measured in degrees. According to a recent study, heat waves do not leave when the temperature drops. They leave a silent trail in the body: they accelerate biological aging. A disturbing finding. A recent study Posted in Nature Climate Change It has shown that repeated exposure to heat waves accelerates biological aging. The work, led by the University of Hong Kong, followed 25,000 people for 15 years in Taiwan. The results speak for themselves: four extra days of heat wave in a period of two years were translated in nine days added to the biological age of the participants. In manual workers, more exposed to the sun and heat, that effect shot up to 33 days. “The impact of heat on our body is comparable to tobacco, alcohol, poor diet or lack of exercise,” The research team has summarized to The Guardian. The biological clock under pressure. How did they get to that conclusion? The scientists calculated the biological age from different markers: blood pressure, inflammation, cholesterol and the functioning of lungs, liver and kidneys. When comparing them with the real age of each person, the conclusion was clear: who had spent more time under heat waves showed accelerated aging. The exact reason is still unknown. The main hypothesis is that high temperatures damage DNA and submit the body to constant stress. “If the exhibition accumulates for decades, the impact on health will be much greater than we have now measured,” has pointed to The Guardian Dr. Cui Guo, main author of the study. More evidence: heat at all ages. This finding does not come alone. In 2024, another job Posted in Nature He revealed that early exposure to cold and heat interferes with the development of the white matter of the brain in children. The consequences, the authors warned, could extend throughout life. The conclusion is clear: heat does not understand ages. Inference affects developing brains; In adulthood, it accelerates the organism’s wear. Can the damage be stopped? The same study offers an interesting nuance: the harmful effect seemed to be reduced over time, probably because people learn to protect themselves better. Searching for shadow, hydrating or using air conditioning made a certain difference. Even so, the biological footprint never disappeared completely. The problem is that not everyone has the same possibilities to adapt. Older people, outdoor workers or those who live in neighborhoods with less resources suffer a much greater impact, As the study collects. Prevention, experts coincide, goes through reinforcing Urban design: More trees, more shadow, better isolated homes and just access to cooling. Individually, recommendations remain simple but effective: hydrate, avoid hours of heat and seek refuge in fresh places. The invisible heat scar. Until now we thought about heat as something passenger: annoying, exhausting and dangerous in extreme days. But scientific evidence points to something more disturbing. The heat, the experts say, does not leave at all when the thermometer goes down: it stays inside, accelerating the wear of the organism and leaving an invisible scar. For researchers, this finding is a turn in the way of understanding health. And the warning is clear: if the planet continues to heat up, we will not only have longer summers, also bodies that age faster.

The answer was on the other side of the Pacific, in Japan

It is not enough to promise that a plane is less noisy. You have to prove it. That is what NASA proposed with its X-59an experimental plane that wants to change The future of supersonic flight. To achieve this, I needed data. Very precise data. And therefore, although the project is American, a key part of validation was carried out in Japan, in one of the supersonic reference facilities in Asia. The X-59 Quesst is an experimental plane created with a very specific mission: demonstrate that it can be flown at supersonic speed without that meaning a rumble on land. What NASA wants to eliminate is not speed, but noise. The classic boom Sonic, that dry burst that rumbles when an plane overcomes the sound barrier, remains one of the great obstacles for supersonic flight Return to commercial aviation. The X-59, on the other hand, promises something different: A slight THUMPbarely noticeable from the ground, thanks to a design that controls – and disintegrates – the shock waves before they are based on an acoustic explosion. But it is not enough to design a stylized and elongated form. It is not enough to simulate it on a computer or anticipate its behavior with computational models. What defines X-59 is not only its silhouette, but the sonic firm that projects When flies to Mach 1.4. That firm, that acoustic footprint should be measured with surgical precision. And that’s where Japan enters the scene. NASA did not do everything at home: key part of the validation was done in Japan Although the epicenter of the project is located in Palmdale, California, under the direction of Lockheed Martin Skunk Works, part of its most delicate validation was carried out on the other side of the planet. Instead of limiting yourself to try your model in your own facilities, NASA decided to repeat the trials In a supersonic wind tunnel of the Japanese space agency (Jaxa), located in Chofu, Tokyo. There, researchers from both agencies They exposed a plane modelreduced to 1.62 % of its actual size – 50 centimeters from tip to tail – to conditions that simulated its cruise speed. The objective was clear: to verify how the air flowed around the aircraft and, above all, register with the highest possible precision level its sonic signature. Japan’s choice was not symbolic. As NASA itself detailsthis was the third round of wind tunnel tests carried out with that same model: one was made in Ohio, at the Glenn Research Center; another, in the same Jaxa tunnel years before; And the latter, also in Chofu, was raised as part of a cross validation strategy. Even if you put the model in another wind tunnel, a slightly different version of the data is obtained, that is something good, Melissa Carter explainedresponsible for the NASA Supersonic project. “By using the same model in both tunnels, we can increase the certainty of the data and our understanding of the X-59 design.” The measurement of the pressure profile – the acoustic footprint that leaves the plane when it breaks the sound barrier – does not admit errors. And the best way to reduce any margin of uncertainty is to verify that, under different conditions And with independent instrumentation, the results remain consistent. That is what allows collaboration with Jaxa. As part of an agreement signed in 2020both agencies pledged to share data, compare methodologies and repeat essays in both countries, thus reinforcing the solidity of the entire experiment. The wind tunnel where the tests were performed is not any. It is a supersonic installation operated by Jaxa, with a section of just over a meter by one meter. Although their dimensions may seem modest, they are ideal for working with very small models such as X-59. In it, the air flow can reach sufficient speeds to simulate real flight conditions, which is just what NASA engineers were looking for. For Jaxa, the opportunity was also key. The Japanese agency has been developing its own “silent” supersonic flight program for years, With projects like Sky Frontier. Sharing information with NASA allows you refine your own designs, Learn from different approaches and validate your simulation tools with real data. In return, it offers experience, equipment and infrastructure that complement those of the United States. Images | NASA (1, 2, 3) | Roméo A.
