Why the airlines continue to force us to put the airplane mode in 2025

by

“Please be sure to put your electronic devices in airplane mode Before takeoff. If your device does not have a plane mode, bring it completely during the flight. ” Something similar to this message is reproduced thousands of times every day in the world and, although not everyone pays attention, a usual gesture when sitting on the plane is to connect the plane mode. 25 years after birth The plane mode, although the message continues to reproduce, it is no longer mandatory to put the mobile in plane mode. However, there are pilots who continue to defend their use for a reason: their comfort. It made sense. The airplane mode was born as a result of a concern: the possible electromagnetic interference that electronic devices could cause in both communication and navigation systems in airplanes. It was a possibility, like the one that existed of light fourth to gasoline in gas stationsbut the chances of a catastrophic failure They were very low. However, to mitigate any potential risk and guarantee safety, the measure of prohibiting the use of electronic devices during certain phases of the flight was adopted. Fiction has contributed to still thinking that something can go wrong, such as the moment of ‘The Simpsons‘In which Bart is playing with a Game boythe hostess asks him to turn it off and, in doing so, the plane begins to plumn). As these devices advanced and added more networks, Wi-Fi, Bluetooth and more powerful connections, the “plane mode” was adopted that disable these transmissions. And, as the main motivation of this function was its use in commercial flights, the name and icon of the plane was consolidated although its use was recommended in other environments such as hospitals or the aforementioned gas stations. 2014 and 5G. After implanted and turned into A standard for several devicesin 2014 things began to change. In September, the European agency EASA He gave the passengers free to use their electronic devices without plane mode. That most lax attitude left the ball on the roof of the airlines, which could maintain or not the mandatory use of the airplane mode and, in fact, many have adopted internal Wi-Fi systems that allow them to earn more money. One of the famous Extras of the companies. Asterisk. While the plane is not going to fall, the use of this way is still promoted for a very specific reason: the crew comfort and controllers. These years, in well -known blogs such as’Ask The Pilotor like Some pilots commentAviation experts have appeared that comment that the way to prevent an annoying buzzing for communications is recommended. And it is logical. As Comment The pilot Rafa San Julián, from Iberia, the aircraft teams are “much more protected than formerly and are much less vulnerable.” Now, the plane mode is still recommended for a very specific reason: technology and Power of mobile networks It advances every few years and “it cannot be predicted if these interference will occur with the new equipment. Therefore, as a safety measure, it is requested that the mobiles put in plane mode so that they do not emit with the same power with which they would issue without that mode,” he says. Concern by the way 5g. And block with what Boeing detected a few years ago. FAA, which is the US aviation agency, He issued Directives warning about possible 5G signal interference in band C (3.7 to 3.98 GHz in the US) Be too close of the frequency used by the radio heights of Boeing and Airbus aircraft (4.2 to 4.4 GHz). These radio altimeters are essential in landing maneuvers and in other systems such as soil proximity notice. The concern would affect airplanes such as Boeing 737, 747, 777 and 787, and would force pilots to perform landing maneuvers in safe and more manual mode. However, no serious accidents or incidents have been reported due to this interference and, if They have canceled or delayed flightsit was due to an increase in caution. In fact, FAA itself command Shortly after a message of tranquility. That distance of 0.22 GHz It is enough As if there are no interference, but at that time it was not more caught. Fly calm. Therefore, not remove the plane mode during a flight will not make the plane fall, but it can generate a buzz or White noise In communications, being annoying for pilots and controllers. Activate it is a good idea to save battery and so that if you are going through a country without roaming and remotely get coverage, do not charge you five euros for downloading a WhatsApp message.

A century of herbivores at ease was ending with Yellowstone. Salvation was logical: call the wolf

by

‘Jurassic Park‘He has memorable moments, but perhaps a phrase is the one that fell me the most in his day: “Life makes its way”The problem is that the hand of man exercises Too much influence on natureand the Yellowstone park It is an excellent example of how an ecosystem that was regulated perfectly was twisting due to a decision made 100 years ago: eradicate the wolves. Consequence? May the park run out of trees. And to turn to the tortilla, the researchers had an idea: return to repopble Yellowstone with wolves. Yellowstone in short. The arrival of European settlers to the North American west caused the expansion of the agriculture and, above all, livestock (With grazing and the Basques carrying the reins). The enemy of cattle was the wolf, since it was a direct threat and, due to its vital role for the local economy, extermination campaigns began to be carried out. The result was that, by 1930, the wolves (as well as other predators such as pumas, coyotes and bears) practically disappeared from some areas such as Yellowstone. Even the army is implied. If the predators disappear, those that were their prey have free field to reproduce without control, and that caused that alces and deer proliferate, creating a huge imbalance in the population of herbivores and, therefore, in the flora of the park. In the end, overparation and a overpopulation of wild herbivores caused the trees to disappear from Yellowstone. Lobos, to curra. The trees that worried were the scenes and it is not a matter of the alces to stay without food. How can we read in Oregon State UniversityThey are vital elements for birds that nest in them and for beavers, among other species. Thus, in 1995 the decision of V was madeOlver to incorporate those predators to the ecosystem. Lobos, Bears and Pumas, another predator practically removed from the area, returned to the place they should never abandon, and the results have not taken to appear. Results. Luke Painter, professor of ecology and conservation at the Faculty of Agricultural Sciences of the University of Oregon, comments that “The reintroduction of great carnivores has started a recovery process that had been paralyzed for decades. ” studyThey detail that the “price” is the sustained decrease in population of the Cervus canadensisallowing the quarrels to experience exceptional growth. This “trophic waterfall” examined 87 rhods of poplars in northern Yellowstone, finding that 43% of them presented a new population of small trees between five and ten centimeters in diameter, being the first positive count since the 1940s. They comment that the density of grazing remains the dominant factor for the regeneration of poplar, but that that Introduction of predators has relieved the load that herbivores exert in the ecosystem. In addition, the study rules out changes in the climate as the main cause of that recovery, once again influencing the importance of the reintroduction of the wolf as the element that has caused “changes in the distribution of the ALCE, giving rise to recovery”. The Wolf as a lever. Not everyone is on that ship. A previous study On the part of researchers at Utah State University and the University of Wisconsin Stevens Point put on the table that, although the role of the wolf had been important for the recovery of poplar, its role was exaggerated due to the way in which previous measurements were made. But what has happened in Yellowstone is not an isolated story. That persecution of the wolf has been lived in other areas and, in Europe, due to its impact on livestock, they are also promulgated laws for extermination. The ecological consequences are similar to the views in Yellowstone and, in Scotland, there is an overpopulation of red deer that are ending local forests. At a time when we need trees so that They catch co₂it is already being raised release more than 150 wolves in the ‘Highlands’ Scottish to control deer and save forests. While some release them… But as we are condemned to repeat the story, at the end of 2024, the Permanent Committee of the Bern agreement voted in favor of reduce wolf protection status. This makes it “strictly protected” to “protected”, which opens the door to A desire on the part of certain parliamentariansfarmers and hunters: that can bother the wolf. And not with paint ballsas in Netherlands. In Xataka | Russia has found a frozen wolf 44,000 years ago “in perfect condition.” First decision: open it

A United Kingdom restaurant makes history with its first water letter. Free tap water also serves

by

If we look for the definition of a sommelier, the RAE It presents us with the following: “Wine expert and liquors who, in large hotels, restaurants, etc., suggests customers the appropriate drink for the occasion.” Do not go to the SAR: Wikipedia It says the same. We understand by sommelier, or Sommelier, an expert in pairing who knows which wine fits better with different dishes. Amazon even has a ‘telesumillers’ servicebut there may soon be a new meaning for Sommelier: Water expert. In 2011 the Water sommelier uniona professional and international association that was born in Germany and that appeared with a single purpose: to promote the professional, training and economic interests of water sommeliers to defend the culture of mineral water. It is not the only one that exists, since there is also the Doemens Academy In Germany or the Fine Water Academy In the United States, as well as some associations in countries such as Italy or China. And, in the same way that there is a wine letter in some restaurants, the objective of these water experts is that there are unique premises for a very specific reason. A select water letter. Wine letter … and waters Doemens is very clear that “Not all waters are the same”And, apart from giving training in German, English and Mandarin, in 2024 they began to form Sumillers in Spanish. Describe The task of the sommelier of water such as “disseminating and providing knowledge about the quality, characteristics, variety of brands and the value of excellent mineral waters.” Although it is a minority, in the international panorama, profiles such as Martin Riese, the first ‘Sommelier’ Certificate of the United States, but also the British Doran Binder begin to flour. Binder, with a very active profile in Instagramwhere he has more than 55,000 followers, he is a sommelier who supplied the water of his brand -crag spring water- to the British restaurant The Popote. It is a French -style restaurant that is in the Micheli GuideNY in which they have a letter with about 140 varieties of wine. At some point a few years ago, and as they expose in CNNBinder approached the owners of the Popote to propose something: a menu of water. At first, they thought “It was a ridiculous idea”but they changed their minds when they attended a water tasting. Of that “ridiculous idea”, the owners went to “the water is not just water.” The tasting was similar to what is done with beer or wine. First, they tested about six varieties, but then made a second tasting with the same waters, but accompanied by food such as Manchego cheese, comte, chocolate, olives or parma ham. That’s when they realized that the taste “changed” and that they appreciated that certain waters married better with certain foods. Convinced, they let Binder devise the menu, becoming the first in the United Kingdom to have a Water letter which offers its product (five pounds per bottle) up to 19 pounds, about 25 euros, for The Palace of Lifego, a gas with gas from Portugal. There are also Spanish, Italian and French waters. Binder with your water letter Ok, very good, but … what are you selling me? According to Binder, the water key is TDS, or dissolved total solitos. In the statements to CNN, “the measure of minerals is what determines the flavor and taste. The destined water has a zero TDS.”It is fantastic for cleaning windows and for the carbut lousy for humans, ”he said. The range it offers in the restaurant goes from the 14 TDS of the mineral water with Lauretana gas to the 3,300 of Vichy Celastins. The Vichy Catalan, which is another product that is usually seen in waters, It has about 2,900 TDS. At the opposite, sea would be between 30,000 and 40,000 TDS. From Spain we have ’22’ that is soft in the mouth, with a delicate profile And it is, as with wine, to extol the taste of everything. If the French water they serve is “quite salty, you have to combine it with something that is saved, like a parma ham, and both are balanced. So, the water no longer knows salty and what remains is a more durable flavor of the ham in the mouth,” says Joseph Rawlins, owner of the Popote. Eye, they also have tap water as courtesy. I imagine that it will be equivalent to Ask for a torrefact in a specialty cafeteria. Apart from this, in a context in which Alcohol consumption is decreasinghaving “gurmet” options of without alcohol is something that makes all the meaning. How to serve the water In the end, it is what is sought when you seek to exalize flavors mixing elements that seem not to stick, such as salt chocolate, for example. If we want to do this at home, there are tricks. Joanna Vallejo It is a wine sommelier that has also specialized in the water and has offered some tips To enjoy at home a better experience when enjoying water and rest of food: Read the label to find the origin. If you drink wine, accompany the glass of a glass of quality with gas, since that acidity point will make the flavors of the wine are enhanced. Use correct water. For example, for spicy or acids, use gas with gas. For softer foods such as salads or fish, waters with less minerals. And for more forceful meat or food, water with a higher mineral profile. Do not put ice in the glass because what you will do will be the same thing that happens with coffee: to await and mix a high profile water with another that is from the tap (no matter how good some are). And the most important thing about this (because, like me, you have raised an eyebrow thinking that now you will have to wear a monocle every time you are hot and drink a glass of water): Joanna herself comments that It … Read more

more repentance, more erased clinics and professionals who live worse than before

The tattoo has gone from be a symbol of rebellion to A fashion accessory. Soccer players, Influencers And even your fifth neighbor look like skin designs. This massive acceptance caused an unprecedented boomFilling Spain with studies and artists. But the party is over. The bubble seems to have exploded and has left behind a precariousness and also repentance panorama among the different clients who decide to remove their tattoos. Regretting what they tattoo. A phenomenon that we are seeing right now is that of Delete what one day was permanent in their skins. This was demonstrated by a study Made by Lutronic PBSwhich pointed out that 60% of the people who tattoo in our country end up regretting. The problem that arises is that eliminating a tattoo is not easy to do. The ink that is injected directly into the skin dermis, which is the second layer of the skin. This causes an aggressive treatment to be able to eliminate it completely. The number of professionals who remove them increase. The demand for withdrawing tattoos makes new treatments and clinics appear. In 2023 it was recorded A 30% increase in the number of demands regarding eliminating tattoos through laser technique. And is that choosing a good professional It is fundamental so that later it is marked on the skin. And such is the ‘fashion’ of eliminating tattoos, which even in social networks can already see how trends and up as #Tattoremoval where The before and after this treatment is shown. And sometimes people make these tattoos impulsively Without having anything clear. And then the repentance is there. The tattoo sector has a ‘dark side’. In addition to the change of opinion of many consumers of this art, The avant -garde has collected in a report As the market has changed radically. Raúl, a professional tattoo artist since 2001, reports that when he started in this world, the coil machine was an almost artisanal artifact of more than 300 euros. Now this same machine It can be found on Amazon for fifty euros With an initiation kit that includes needles and inks of doubtful quality. This technological democratization has had an immediate effect: a marketing of the market. The National Union of Professional Tattooators and Anillers (UNTAP) esteem That in Spain there are about 10,000 “legal” tattoors, but they estimate that the double works irregularly from their homes. These “home tattoors” They are announced on Instagram and Facebookcompeting directly with studies paid for rent, taxes and health licenses. And this is something that results in a fall in demand to professionals. The ‘Glovo’ model has reached the tattoo. If unfair competition is a battle front, labor conditions are the other. The sector operates in a legal limbo where the ‘false autonomous’ has gained prominence, as they relate to the avant -garde. In this way, they point out that the studies have autonomous tattoors, who carry a percentage of the final price of each tattoo, and the material costs are shared. The point is that some studies would demand to meet fixed schedules of up to 60 hours per week and with imposed vacations. Emilio San Miguel, labor lawyer, is clear about it: as soon as an autonomous depends economically on a single payer and has time and tax holidays, it can be considered a false autonomous. “Almost all the tattooists who work in studies,” he says. ‘Chiquitatus’ and businessmen: the devaluation of art. This panorama has been the breeding ground for a new business model. According to Fidel Prieto, secretary of UNTAP, many of the new studies are not led by artists, but by investors who see tattoo as a simple business opportunity. In this way, they take care of a place with a central location and hire young tattooists, with little experience and more likely to accept abusive conditions. And to be a large production chain, they specialize in ‘Chiquitatu’, that is, a butterfly, an infinity or a small symbol that has a cost of 50 euros. Something that denounces devalues ​​the price of this work, and makes people have to work from their home and in black so that it deserves the penalty economically. Because becoming autonomous is something that many people cannot afford. What you earn in the trade is not very attractive. As they point out in the report, a tattoo artist can have a good month and invoice about 3,000 euros gross. But It is not a stable tradeand depends on the number of customers you have. In this way, in a bad month those income can collapse up to 700 euros easily. A tattoo artist, Virordia, points to that I would prefer to have a decent salary, a normal schedule and decent conditions. The situation is as unsustainable that figures such as the “false hired” have emerged: a 10 -hour weekly contract for someone who works more than 45. The objective is to reduce the social security quota, a desperate patch in a broken system. Tattoos have a future beyond the aesthetic. Although many people are tattooed for pleasure, science explores other options. For example, it is already explored to use them as a system to control blood glucose or go much further to Be authentic biosensors to analyze other biochemical parameters of our organisms in a little invasive way.

The effect of heat on our heart rate when playing in summer

by

It is the summer stamp: go running or riding by bike and, a few minutes later, the pulsometer is triggered to figures that do not correspond to the effort. And it’s not a strange thing to see. It is the body that is trying to respond to a series of stimuli such as heat and exercise, and understanding its physiology is important for Do not turn sports into a health risk. Exercising in summer is a great challenge. In this situation the body is forced to respond to two specific demands. On the one hand, Muscles in action need a lot of energy in the form of ATP To contract. However, this is an inefficient process, since It only takes advantage of between 20 and 25% of the ‘produced’ energy releasing the remaining 80% in the form of heat. This energy in the case of not dissipating it correctly can raise internal body temperature by 1 ºC every 5-10 minutes. How to avoid it. On the other hand, to avoid precisely that lethal overheating, the body thermoregulatory center located in the hypothalamus, Activate powerful cooling mechanisms. One of them is to pump huge volumes of hot blood from the body nucleus to the skin, causing it to be red by that large amount of blood that is going through the surface of the body. This double duty is the fundamental reason why the pulse shoots and becomes the most sensitive and critical indicator of the stress to which the body is subjected The organism has to compensate. These two situations cannot be carried out in parallel, but A balance must be achieved. And it is that when the system is taken to the limit by the intensity of the exercise and the severity of heat, something has to yield. Or blood flow is reduced to the muscles, limiting the ability to maintain rhythm, or the flow to the skin is committed, limiting heat dissipation and increasing body temperature to dangerous limits. Understanding this internal negotiation is key to understand why training in summer is much more than a simple matter of willpower. The skin becomes a giant radiator. The first and most powerful response of the body to the increase in skin temperature and body nucleus It is body vasodilation. Controlled by the ‘thermostat’ of the body, the preoptic area of ​​the anterior hypothalamus, this mechanism causes the blood vessels close to the skin to widen and make it become a refrigerator. Under resting conditions and neutral temperature, the cutaneous blood flow is just about 300 ml/min. However, during an intense exercise in a hot environment, this flow It can shoot until reaching 7 or 8 liters per minute. Something that also represents around 50 and 70% of all cardiac output. And this is a simple deviation of resources with the objective of dissipating heat by convection and radiation. Although it is not free. It has an important cardiovascular cost. The heart accelerates to compensate. The fact of opening the ‘pipes’ that lead the blood to the skin causes the heart to have to activate an important compensation mechanism so that the organs remain perfused. We talk about heart rate, which will be increased. The objective is to maintain cardiac output, so that blood pressure is stabilized despite the low peripheral resistance due to vasodilation. A crucial aspect of this process is speed. The initial increase in heart rate is an incredibly fast neural reflex, triggered by Thermal skin receptors. This response often precedes any significant increase in central body temperature. This shows that the body not only reacts to heat, but anticipates it, preparing the cardiovascular system for the thermoregulatory battle that is coming. The key is in cardiovascular drift. Any athlete who trains with a pulsometer in summer will have noticed a disconcerting phenomenon: even maintaining a constant rhythm, the pulse tends to rise progressively throughout the training. This is something that has been documented and called ‘cardiovascular derives‘, which is defined as the gradual and continuous increase in the heart rate that occurs during a prolonged exercise of constant intensity, accompanied by a decrease in systolic volume (the amount of blood that the heart pumps in each beat). And precisely the heat stimulates the two mechanisms that drive this phenomenon: The increase in skin flow by vasodilation. This causes blood to ‘stagnate’ temporarily on the periphery, which reduces venous return. This means that the heart does not fill so much in each beat, and therefore the amount of blood that will expel will be less. Dehydration Sudoration is essential to cool the complete system, but it entails a loss of body fluids, mainly from the blood plasma. This again reduces that the blood returns to the heart so that the same volume can be pumped. And to compensate the only thing left is to increase the heart rate. The pulse increase per centigrade grade. Once the ‘why’ of this increase in heart rate is known, an athlete is interested in knowing the ‘how much’. And the reality is that studies have established a very useful general rule to know how our body temperature increases when exercising: In dry heat conditions, with environmental temperatures above 24 ° C, the heart rate Increase approximately one beat per minute for each celsius degree of temperature increase. In wet heat conditions, the impact is multiplied. Here the increase in heart rate triggers between 2 and 4 beats per minute for each degree Celsius that increases the ambient temperature. This difference is not trivial. Exercise at 34 ° C in a dry climate (10 ° C above the threshold of 24 ° C) could involve an increase of about 10 beats per minute in the heart rate for the same effort. On the other hand, to those same 34 ° C, but with a high humidity, the increase could be 20 to 40 beats per minute. This additional load on the heart explains why we call as ’embarrassing’ feels much more … Read more

More and more voices think that keeping food in plastic is not a good idea

by

A kitchen that boards has a drawer up to numerous tuppers with the tapas on the other hand. Although it is not the only place, we open the fridge and find even more stacked: some keep the leftovers of noon, others contain freshly taken food from their original container. Behind this daily life – so assumed that goes unnoticed – hides an uncomfortable question: are we storing our food well? The plastic under suspicion. Light, cheap, resistant: plastic became the great ally of modern cuisine. However, recent studies call their safety when they come into contact with food. A BBC report He explained That thousands of chemicals are part of their composition and that some can migrate to food, especially when they come into contact with fatty, acid or hot foods. The problem is not only the food we keep, but also the use we give: the microwave, the dishwasher or the rayons due to repeated use accelerate the release of compounds. And microplastics. To them is added another invisible problem. As Delish magazine has pointed outtuppers release microplastics, tiny particles that have already been found in blood, lungs and even human placenta. A health problem. The debate about tuppers is not a simple kitchen detail: what is at stake is hormonal health. Many of the compounds that migrate from food plastics are classified as endocrine disruptors, substances capable of altering the balance of our hormones. The best known case is bisphenol A (BPA), used for decades in rigid plastics and linked to fertility and development problems. The European Food Security Authority (EFSA) recently reviewed its safety and reduced tolerable intake at a level 20,000 times lower than the previous one. Something similar happens with phthalates, employees to give flexibility to plastic and also associated with hormonal and reproductive alterations, As the BBC has detailed. Plans b. However, trusting alternatives is not a guarantee either. The Guardian He has warned that compounds used as BPA substitutes – the so -called BPS and BPF – have similar effects on the body. AND, According to a study cited by The I Papermore than 3,600 chemicals of plastic containers present in humans have been identified, many of them barely studied. Therefore, some expert voices are overwhelming. Lisa Zimmerman, from Food Packaging Forum, summarized it like this For the same medium: “If you care about your health, you should throw your plastic tuppers and use glass or steel.” The stations also influence. Beyond chemicals, summer heat adds another threat: bacteria. In statements collected by El Confidencialdietitian Judit Carreira, from the Sant Pau Hospital, explained that high temperatures favor food poisoning. Its advice is clear: transport the taperes in thermal bags or portable refrigerators, avoid exposing them to the sun and, above all, separating raw cooked in the fridge to prevent cross contamination. “When you return from the supermarket, the meat and the raw fish should be removed from the container and stored in a clean taper,” He has insisted. He also remembered the four basic food security rules: clean, separate, cook and cool. So, throw all my tuppers? It is not about emptying the kitchen, but of changing habits. Various media They coincide In a series of recommendations: Avoid reheating in plastic: although the container indicates “suitable for microwave”, heat accelerates chemical migration. Reserve them only for cold or dry foods, never for oily, acid or hot meals. Replace them if they are scratched, deformed or with persistent smell. Opt for glass, steel or ceramics for hot meals or prolonged conservation. Now, not all alternatives are perfect. Ceramics, although it is considered safe if it is certified, can be a problem in cases of artisanal productions. The mail reported a few months ago The case of a family of Getxo (Vizcaya) poisoned with lead after drinking for years of an enameled ceramic jug bought in Andalusia. Lead, prohibited in pottery since the 60s, can cause abdominal pain, anemia or neurological alterations. An easier life, at risk. It is true that tuppers have made our lives easier, but they have also exposed us to a chemical soup not yet known. Science still investigates the cumulative effects, but there is consensus on something simple: heat, fat and plastic do not combine well. Perhaps the true luxury of modern cuisine is not accumulating containers of all sizes, but choosing containers that take care of our health.

More and more people are stopping publishing things on their social networks

by

There was a time when opening Instagram meant to look out to the life of our friends. A smoking coffee under the Valencia filter, a badly framed selfie on the beach or the pet of a colleague yawning. It was an improvised, domestic showcase, a mural of shared banalities that, paradoxically, made us feel closer. As The New Yorker recalledthat “breakfast photo” represented the utopian dream of social networks: that millions of common people could publish fragments of their lives with minimal intervention, from the most trivial to the most intimate, and that that worldly record became something valuable, a “dynamic file of reality from the ground.” More than a decade later, the landscape is another. Yes in 2018 The BBC calculated That about 40% of the world’s population used social networks, dedicating about two hours a day to share, today users are still connected, but less and less willing to show their lives. From vacuum feed. The decrease in the public use of networks is already evident. According to a Morning Consult report28% of Americans publish less than a year ago, compared to 21% that does more. Among generation Z, just 18% admit to posting daily. In a recent article, the BBC has confirmed the trend: One third of users publishes less than before, with a descent specially pronounced among those under 30. And the phenomenon is not limited to the United States. In Spain, Iab Spain has presented the 16th edition of the Social Network Study 2025in collaboration with praise, which confirms a similar wear: 33%of Internet users have abandoned a platform in the last year, especially X (28%) and Facebook (15%), but also Pinterest (15%) or LinkedIn (12%). The main reasons are the lack of use, loss of interest and boredom. The hangover of publishing. This withdrawal has even its own name. National Public Radio (NPR) He has baptized it as Grid Zero, The Instagram phenomenon in which more and more young, especially from the Z gene, erase all their publications and leave their profiles as a “blank canvas.” Adam Mosseri, Chief of Instagram, acknowledges: “Adolescents spend more time in private messages than in stories, and more in stories than in feed.” Instagram itself has detected that young people prefer ephemeral or private interactions. His cultural researcher Kim Garcia has summarized it as follows: “Gen Z has award to permanence and the fingerprint. They do not want their entire personal change process to be publicly exposed.” According to NPRhe Grid Zero It works as an immune system against digital addiction: hide the feed, take refuge in the intimacy of chats or private accounts is a way of protecting. This modesty contrasts with the millennial era. For those who border medium age today, networks were the natural space of the exhibition. The hangover was predictable, as the writer Kyle Chayka has pointed out In an interview with the BBC: “We learned the disadvantages of sharing your life online during the 2010s.” Unless you want to be an influencer, it is no longer worth it: the disadvantages of publishing are too large and the advantages do not reach. ” Privacy and fear of judgment. The FEED blackout responds to different variables, but the first is the need to take refuge in oneself. According to online psychologymany users choose not to publish to protect their privacy, take care of their mental health and avoid risks such as harassment or unnecessary exposure. However, in the case of gene z the phenomenon is more extreme. The nod mag He explained Digital hyperconcience: a simple “like” can be interpreted as a political or identity statement. The fear of cancellation leads many to interact as little as possible. The young Kanika Mehra (24) He has recognized it for The New Yorker: “We are all voyeurs now: we keep looking, but we no longer post, because publishing generates a ram of vulnerability.” To this climate is added the sensation of inadequacy in the midst of global crises. A waitress in Washington has told The New Yorker that he erased some happy selfies because “with everything that happens in the world, I was ashamed to seem frivolous.” From the social to consumption. Beyond personal motivations, there is an undeniable fact: almost everything we see today in networks is consumed. “The platforms have become less social; they look more like television, full of mercantilized content, lifestyle aspirations and advertising,” Chayka has summarized in the BBC. Besides, The New Yorker also coincides: The feeds are dominated by influencers, war headlines, political propaganda, videos generated by AI and “sponcon.” Amateurism, the initial engine of the networks, was replaced by careful production and light rings. And the data are there to confirm it: Morning Consult He has found that more than half of adults (52%) perceive the content of networks as “repetitive and tired.” And the Wall Street Journal He has pointed out that users feel that “the community is no longer there”; Instead, there is an endless commercial showcase. Although it is not an empty network. Silence in the feed does not mean abandonment of the platforms. On the contrary: we remain connected, but we move to more intimate spaces. Mosseri He has recognized it in an interview cited by WSJ: “All sharing between friends is going to direct messages. Today more photos and videos are sent by Stories, and more for stories than by the feed.” The BBC Reaffirms the turn: Personal content “has been oriented towards individual messages and private groups.” In Spain, the IAB Spain study Confirm What WhatsApp is the most used network: 96% of Internet users use it daily. The social did not disappear: he simply hid. Millennials, the new boomers? This hurts, but we enter generational. Millennials – among the ones I included – we grew up exhibiting our online life. Today we appear as the “digital boomers” in the eyes of the gen Z. from the new code They have explained it with irony: Millennial profiles seem outdated, full of poses, … Read more

China has monopolized the battery market in just ten years. And the US only has one solution: South Korea

by

China is the largest electric car exporter on the planet. In 2023 he exported approximately 1.7 million electric vehicleswhich represents more than 30% of its total car exports. Nevertheless, Its international expansion It is being seriously conditioned by the tariffs that are imposing USA or the European Union, among other regions with very serious difficulties to compete with the Chinese electric car. Largely the success of the country led by Xi Jinping in this industry strengthens its leadership in The production of lithium batteries. If we stick to China Fabrica electric cars 57% of batteries that these vehicles use. Catl and Byd are the largest lithium batteries manufacturers on the planet with A market share in 2023 34% and 16% respectively. This Asian country has reached this leadership position due to several factors. On the one hand it is The largest producer in the world of lithium and rare earths, which are the main raw materials used in the manufacture of batteries. In addition, it controls the processing of these materials and is capable of producing large -scale batteries and with a very competitive price. There is currently no indicator that invites us to anticipate that His domain of lithium batteries You will be threatened in the medium term. Even so, the US government is trying to create the appropriate conditions to put an end to China’s leadership in the battery market. South Korea is the strongest alternative to China in the battery industry At the end of July LG Energy Solution, the LG subsidiary specialized in the design and manufacture of lithium batteries, He signed an agreement of 4.3 billion dollars to supply iron and lithium phosphate batteries (LFP) to Tesla for three years. This plan is backed by the current US government and seeks to reduce the global dependence of electric car manufacturers of the Chinese Giants Catl and Byd. LG Energy Solution, Sk On and Samsung Sdi are the main battery manufacturers of South Korea LG Energy solution is The biggest battery manufacturer outside Chinaand, although it is a South Korean company, it is the best asset that the US has to end the Chinese domain. Catl and Byd have in their favor their ability to produce high performance batteries and with a very competitive price, which has caused LG Energy Solution, Sk On and Samsung Sdi, which are the main battery manufacturers of South Korea, Lose market share continuously. In fact, According to the consultant SNE Research Its combined market share has been reduced by 5.4% between January and June 2025. The Trump administration is determined to end this trend, and its strategy is to create in the US the necessary conditions to pave the way to South Korean batteries manufacturers and penalize Chinese producers. To carry out this idea has included A Catl, Byd, Envision Energy, Eve Energy, Gotion, Hithium and other Chinese batteries manufacturers in the list that lists the prohibited foreign entities. The purpose of this initiative is evident: it seeks to prevent US companies from buying batteries and components from China. If, despite this, they will be disqualified when accessing state subsidies.

How much electricity produces each country with renewable energy, exposed in a graphic

by

Europe has been Up on the Renewable Train. This summer they have SOLAR ENERGY PRODUCTION REGRESSESwe are installing new huge wind turbines And, although with contradictions such as import energy from Africait is evident that the continent carries a Cruise speed in renewables. However, that train goes to two speeds, with countries in which renewables are hardly nothing in their electricity generation. And it is something that we can perfectly appreciate on this map elaborated by Visual Capitalist. Vanguard. With Eurostat data until December 2024, we can see that The transition to renewables He goes with the wind in favor. The generation of energy from wind, solar, hydroelectric, the Geothermal and the biofuels They already represent values ​​that exceed 99% of the net electricity generation of some countries. In general, it is estimated that, as of December 2024, the European Union obtained almost 42% of its net electricity from the renewable sources, being wind and hydroelectric plant the fundamental legs of this change. Interestingly, despite all Advances in panel technology and wind turbines, the countries in which renewables are more important have as the protagonist the hydroelectric. This is the case of Albania, which leads the list by generating more than 99% of its electricity from renewables, or Norway. In the case of Denmark, a country that occupies third place, it is the wind that marks the guideline. To the tail… When we said that the train goes to two speeds, we refer to cases such as the Czech Republic, Moldova and Malta. In some areas of Central and Eastern Europe, the fossil fuels are still crucialand the three countries mentioned are the least proportion of renewables in their electricity generation. As a red lantern, we have Kosovo with just 8.8% of its energy from renewables. The sources. Something interesting is to know which are those renewables that are pushing clean energy in Europe. In Spain, for example, We throw ourselves into the arms of the plotbut the energy mix that has contributed to these numbers, depends a lot on each country, and in the European photo, the plot is in third place. According to Eurostat, wind energy meant 39.1% of the renewable energy produced in 2024, followed by 29.9% of the hydroelectric and 22.4% of the solar. The biofuel is far, with 8.1%, and the geothermal energy is marginal, contributing only 0.5%. Situation in 2024 A devastating advance. And beyond distinguishing in countries, if we look at the global situation, we see that more than 40% of the net energy produced by the EU in 2024 comes from renewables. According to Eurostat, 47.3% of electric production, which translates into 1.31 million GW/Hy an increase of 7.7% compared to 2023. Evolution of energy production during the last 35 years In that same graph We can see that fossil fuels have fallen by 7.2% compared to the previous year (almost the same as renewables) and nuclear, despite the plans of some countries, grew by 4.8%. We will see what course this has in 2026, since a Eurobarometer survey carried out in June 2025 Indian Strong support from EU citizens to the adoption of renewables, but we will have to see if that renewable deployment is compatible with another that is being performing ambitious and You need huge amounts of energy: the one Data centers.
