How much meat is too much meat? This is how the debate about meat is changing

by

For years they have told us that meat is a source of protein, iron and tradition. In many cultures, he is the queen of the dish. But today, between the growing public health problems and environmental urgencies, the question is no longer whether we must eat meat but how much meat is too much meat. The answer is not as simple as it seems. The consumption map. The meat is still the protagonist on our tables, but its impact is triggered. In recent decades, its production and consumption have grown accelerated: Statista and Our World in Data They estimate that we could reach 570 million tons per year in 2030, an increase linked to global population and economic growth. Countries such as Spain, France, the United States or Japan, consumption levels They exceed 100 kg per person a year. However, according to A study published in Nature Foodmore than 255 grams of white meat per week already calls into question the planet’s capacity to regenerate the resources that this industry requires. Red meat directly is outside any diet compatible with sustainability, according to Caroline Gebara, main author of the study. Less is more. From medicine and nutritional science, the message is increasingly clear: reduce the consumption of meat – especially red and processed – is beneficial. According to Healthline and studies collected at MIT Press Readerits intake is related to a higher risk of cardiovascular diseases, colorectal cancer and general mortality. In the Course of Integrative Oncology of the University of Santiago de Compostela, the Nutrition Professor Lourdes Vázquez explained for the voice of Galicia that the approach must be integral: “The more foods of plant origin, the better. We do not want to demonize, but the diet set.” From Brussels, the European Union has put figures to the Council: Limit red meat to 300-500 g per week, and the prosecuted to no more than 30-150 g, depending on the country. In the Spanish case, food guides recommend from 0 to 3 weekly portions, with preference for white meats such as chicken or rabbit. What evolution says. We know that humans have eat meat for thousands of years. What is not so clear is when he started playing a key role in our diet. ORn study commented in The Conversationwhich analyzed nitrogen isotopes in fossil teeth of Australopithecus in South Africa, suggests that these predecessors ate mostly plants. However, a opposite hypothesis, cited here in Xatakastates that during much of the Paleolithic we were hypercarnivores, hunting large mammals and developing physiological adaptations for frequent consumption of meat. Faced with both positions, the biologist Gidon ESHEL questions the usefulness of appealing to evolution to justify modern habits. In your essay for Mit Press Reader He has affirmed: “Evolution does not prescribe our current diets. If more than two out of ten plant foods can nutritionally replace meat, then meat is not indispensable.” Leave it at all? It is not necessarily about becoming vegetarians or vegans overnight. There are gradual alternatives, such as Pescetarianismbased on vegetables and fish, or the flexitarianisma more flexible option that does not eliminate meat, but yes It reduces its frequency and quantity, promoting the consumption of legumes, vegetables and integral cereals. They are only different approaches that show as a bridge to adapt to different personal, cultural or economic contexts. A more conscious diet. So how much meat is too much meat? The answer is not an exact number, but an invitation to moderation. Eating less meat, better quality, accompanied by more vegetables, fruits and legumes not only improves individual health: it is a specific measure to preserve the planet. Reducing meat consumption does not imply giving up the pleasure of eating. It means adopting a way of feeding more conscious, informed and sustainable. As concluded The study published in Nature Foodthere are many dietary combinations that allow to maintain health and take care of the environment. It is not about prohibiting, but about transforming.

The debate about whether it is better to walk quickly or walk slowly is settled. At least if what we are looking for is our health

by

Walking is an exercise that not only has the advantage of helping us maintain good health, it is also affordable for people with difficulties to exercise in other ways due to circumstances such as age or rhythm. However An old debate persistsSI for extract the benefits of this exercise We can go with a relaxed step or if on the contrary a prescription rhythm is essential. If there are no reasons such as injuries that can be aggravated with sports, physical activity, even in “small doses”, it will always be better than inactivity. That is why the debate about the ideal of walking slowly suits us is easy to settle: walking slowly is better than not walking. Of course, experts tend to agree that, if we have the possibility, better to accelerate the step. Walking can help our health in different ways. Our heart health is, surely, the one that can be appreciated most to wear comfortable footwear and go for a walk, but it is not the only one. Walk has been related to a lower impact of diseases such as diabetes but can also have psychological benefits such as stress reduction or help Improve concentrationespecially when we walk through natural environments. But then what about the Benefits of walking quickly? Again, cardiovascular health is in the center of the debate. A study Recent in highlighting this is the one published in 2024 in the magazine Atherosisclerosis. The study, which had almost 20,000 participants, analyzed their mortality in a period of 9.4 years. The team responsible for the analysis detected an inverse relationship between the rhythm with which they used to walk and the risk of death and suffering from cardiovascular diseases. Studies that relate the rhythm of our gait with the benefits that walk gives our health They are diverse. Some also cover the relationship between speed and cognitive deterioration. Some examples are found in The review published in 2016 In the magazine Ageing Research Reviews. The team responsible for the analysis found a relationship between the speed of the passage when walking and the cognitive deteriorationalthough it was not conclusive about the existence of a direct causal relationship since it could also be cognitive deterioration that makes us walk more slowly. Lose weight Weight is an important risk factor in many diseases. That is why, although thinning does not have to imply that we will be healthier, it can be useful to reduce this risk or as a simple motivation towards healthier habits. Among them, exercise. If our goal is to lose weight, accelerate the step It can also be helpful. Of course, the context can be important, as a group of researchers recently discovered. In Your studypublished in 2024 in the magazine Sports Science & Medicine, They detected that Genetics could be decisive when reducing our weight through this type of exercise. Walking is an affordable and healthy exercise, but science finds more and more evidence that it is best to accelerate the step if we want to make the most of the benefits of our walks. Walking, even at a leisurely rhythm, can help our health, but can also help us take the habit necessary to direct us, little by little, towards a more active life. Step by step.

There are people using AI to “invent” their own memories from photographs. And that has opened a philosophical debate

by

In the photo the kid smiles, abholly happy. His mother, also smiling, hugs him while looking at the camera. The photo could be that of any of us with our mother, but with this happens one thing: that an AI has made it a video. One that immediately has the potential to become a memory. A memory of lie. That photo shared it in x Alexis Ohanian, co -founder of Reddit, millionaire and entrepreneur. Ohanian – caught with Serena Williams since 2017 – told in that message how when he created that video innocently “I was not prepared for how I would make me feel this.” In his family they had no video camera, so he never had a video with his mother. So almost without thinking he used that photo in the newly released Midjourney video generator so that from it generated a video for AI. The result left him astonished. “This is how she hugged me,” he explained. “I have seen it 50 times again.” But with that message A great moral and philosophical debate was unleashed. One about how something like this can impact us individually and as a society. While Ohanian himself He defended himself Before those who criticized the idea (“I really don’t understand why you wouldn’t use AI for this”) others They explained to him that those memories were not real: “Creating a video for someone loved is not to create a memory of them. You are putting words they never said in their mouth.” As said Another user named Erich Thilow, “is (a memory). But seeing it will make it real in your memory. I am not a fan of something like that.” Other users took advantage of cinema as the center of the debate. A user named Vanillaelle shared A Harry Potter photogram revealing with a false memory of his parents in the mirror (which has inspired the image of this theme). Another user called Andro toward The analogy with ‘Matrix‘. In that movie, he explained, one to see her wondered why people would want to face reality. “Now he doesn’t have to ask him,” said said user. The era of false memories That new capacity of the generative AI Generate false memories It is disturbing, and it could well be part of that concept already studied in psychology. These lies memories did not happen or are the distortion of a real event, and according to experts, such as the American psychologist Elizabeth Loftus, it is possible to induce them such as hypnosis or with techniques such as the essay: repetitions of an event that was confirmed as fantastic. Upon listening or visualizing the same event, the person can begin to remember as if it had really happened. That idea thrown by this psychologist also collects it Francisco Taberneroclinical psychologist in Puertollano (Ciudad Real). According to him “memories are usually quite distorted”, but for him there is no special risk in that type of process that converts a photo into a souvenir of lie: “The general experience of memory will be subjective and more or less the same we had. I do not think that a few seconds of movement change the memory that you already had. At the emotional level the memory is all emotion, what causes you remains the same as what you have told to the AI.” Loftus – criticized by the pseudoscientific concept he created, the “false memory syndrome” – published A study In this regard, together with Ira E. Hyman Jr., and both explained how “memory is always constructive. People create the past based on the information that remains in memory, in general knowledge, and on social demand to recall situations.” Ethical and moral issues are definitely huge, and to talk about them we wanted to contact more experts. Santiago Sánchez-Migallón (The von Neumann machine) It is defined as a “philosopher of AI” and is usual collaborator of Xataka. For him, “we must understand the emergence of a technology as an opportunity and no, a priori, as something perverse only because of the fact that he treats a delicate issue as, in this case, the death or authenticity of memories.” Sánchez-Migallón makes it clear that the first thing is to make technology safe and that the user “can differentiate true and false memories”, but assured this, this expert thinks that with this technology it would be possible to help “erase traumas” and even imagine a not very distant future in which it was possible to gain procedural memories or skills: “Could we record in our brain the ability to play the piano or talk?” Darío Benítezpsychologist and co -founder of PSYCHOFLIX and of the podcast Validlyit is optimistic with AI, but you see “few or no advantage” to this type of application because “if you are reliving an image of a loved one you expose yourself to an emotion that you did not expect and that can rekindle a type of duel that you had already prosecuted.” Something like that, he indicates, can change the perception of your values ​​because this type of lies memories “can make you feel that you lived them and that that effectively happened.” It is like Ohanian’s own example. For Benítez it could happen that in the video generated the mother looked at the child with a subtle disdain and generated a reaction of the type “yes, it is true that my mother did not treat me at all well”, thus generating a hallucination that connects with another idea that perhaps had of her past, which in that case would be of the type “my childhood was not so good.” All that “would even more entangle things,” says this psychologist. The danger of being able to mold memory An technology also has another danger that we have already perceived in many other technological areas. Especially in mobile phones and social networks, which tend to isolate us and catch us in the doomscrolling. With these videos created by generative, “it could be … Read more

The great debate about whether iOS is safer than Android, myths and realities of ‘Breaking Bad’ and much more in 1×09 crossover

by

Can anyone manufacture your own drugs How did it happen in ‘Breaking Bad’? To tell us about the myths and realities of that series and many other things, he has accompanied us In this 1×09 crossover A very special guest: Breaking Vlad. This well -known scientific disseminator is also an original content creator because of his way of talking about chemical experiments, and in the interview we have been able to do, he answers striking questions about the radiation of phones or about the future of hydrogen cars. Presented as sowing by Jaume Lahoz and Carlos Santa Engracia, in this episode the collaboration of Xataka serves to reactivate an old and controversial debate: If iOS is safer than Android. Both platforms have been really reliable for a long time, and perhaps the problem, as the interview reveals, is another. It is also necessary to separate that debate from another in which Apple does take advantage of Google. One thing is security – things are balanced – and another very different privacy, where Apple’s business model – which is not focused on advertising – allows the company to give more guarantees. In 1×09 crossover there is also a place to make a fun debate about false news that we have seen these days – a Chromecast with integrated Tinder? -, and as we always expect your comments and ideas to improve in upcoming episodes.

The Prado Museum closed its doors so that Dua Lipa could create content. That has generated a furious debate

by

Even the most venerable institutions are taking notes of the latest trends in communication, and that is why dean museums (but not necessarily anchored in the past and the analog) undertake promotion and communication strategies that come out of the normal. The latest: Pop influencers and stars visit Museums. Often, with the buildings closed for them alone. Dua Lipa likes Bosco. This happened with Dua Lipa, who, taking advantage of the fact that he was going through Madrid with the Radical Optimism tour, published some of his leisure plans through the city. One of them was look at the one who affirms that it is his favorite picture‘The Garden of Delights’. Of course, he did it with the closed building, in a promotional maneuver that was conveniently redifested by The Prado Museum account. Dua Lipa is not the first or the only one. What can be done. These types of actions are a content very desired by museums, since they give them a lot of visibility between an audience that is not the usual of their social networks. Among the activities that are usually carried out and that are analyzed in studies like this company Evespecialized in innovative museum projects, highlights private visits with the closed museum, advertising campaigns in which celebrities lend their image, special events and, as is the case, mutual creation of content for networks, disputed in struggle for every second of attention. More cases. As we say, the case of Dua Lipa is not the only one. In 2020 the influencer Italian Chiara Ferragni visited the Uffizi gallery of Florence, in a session for the magazine ‘Vogue Hong Kong’ and with a guided tour of the director of the Pinacoteca. The museum knew how to make good use of the influence of the influencer when comparing its physique with the Renaissance muse Simonetta Vespucci. The photos of other celebrities of high turns, Jay Z and Beyoncé are also controversial, when they are photographed by eclipsing works of art Like Nefertiti’s headimage for which they needed a special permit of the Berlin Museum Neues. Museums are modernized. Actions such as these obey a task of modernization of museums, which of course affect their contents in social networks. El Prado, in fact, has been Very praised for its studied mixture of entertainment and dissemination with a relaxed tone. They started with house experts that explained the intrígulis of the Great works and his restorationbut they currently have a very varied content, with all kinds of disseminators expanding the meaning of the works. It is one New form of art criticism. International tendency. It is a modernization of networks that other museums, such as Carnegie Museum of Art wave Tate GalleryThey have also put into practice. Pioneer was the New York Metone of the first artistic institutions with a Tiktok account and that reached a remarkable impact before the pandemic with initiatives such as #Metgalastyle, where they asked users to create their own content inspired by the famous annual gala. The complaints. Of course, sometimes so isolated proposals from your consumer-type as some of these can collide with the usual ones. For example, Dua Lipa’s videos have been Very criticized In networks because they see how he takes photos in the museum, something that is prohibited for normal users. But there is more: there is talk of a Banalization of artif the Influencers And your concern for Figure in the foreground and ahead of the works (as Beyoncé does) is the correct form to disseminate this type of contentand if This type of digital strategies They end up damaging institutions rather than spreading their catalogs. In any case, it is another symptom of the popularization of culture and how after a while, Art molar again. Much of the fault is the trends that dictate Influencers And superstar, but also, let’s not take me out of merit, that the Instagram account of El Museo del Prado is frankly well.

The True Crime are such success that the creators of the least scrupulous have been thrown over the genre, opening a moral debate

by

He True Crime It is a genre that, Despite its immense popularityis ethically more in question than ever: controversial like The recent book by José Breton They make the public propose the scope and consequences of the documentaries on real events. That now look at a new border, with the creation of content by the based on real events. Or even beyond: completely inventing crimes. The tremendist. “The husband’s secret gay romance with his stepson ends up in a spooky murder” or “the secret romance of a wife with a neighbor’s teenage daughter ends up in a spooky murder” are some of the titles of True Crime Case Files’ videos. It was a channel missing today in which they were related, normally before static images and generated by artificial intelligence, crimes that could go through real. But intentionally, the author concealed the artificial origin not only of the images, but also of the stories, which he generated through Chatgpt. A subgenre. They soon caught the attention, How has 404 averageof journalists from the real locations mentioned in the videos, who were surprised not to have heard of such striking cases. When it was made public that the content was generated by AI, but this was not mentioned anywhere, YouTube canceled this and other channels of its person responsible for breaking the conditions of the platform (among others, “Children’s Security policies, which prohibit the sexualization of minors”). It is still possible to access the content in audio format, however, Through platforms like Spotify. The cartoon is not enough. The head of True Crime Case Files was an AI programmer who had already dedicated himself to generating small parodies of romantic comedies Hallmark type on YouTube o Fill content on social networks such as Facebook. According to 404 Media, he disproportionately exaggerated the details of the cases so that it was evident that it was invented cases but, as with Facebook and Instagram videos obviously generated by thethere are dozens of people who believe them. Other True Crime with Ia. Of course, the case of True Crime Case Files is not isolated, although perhaps it is the only one who has tried to go through real crimes his stories: Cen Stories It has the same visual style, in the images and in the holders, and a disclaimer which warns of the content generated by AI, although the notice appears only in the description, buried between summaries and hashtags, and not within the video itself. In Tiktok they also abound, always specifying its artificial origins, and in innumerable variants. In Detective Challenge The cases are invented, and in Thruecrimeaimedia real facts are mixed with invented. There are channels in Spanish, such as Based cases And others who not only tell crimes, such as my history, but also introduce morbid cases of historical cases, such as Nero’s castrated lover or make popular cases of cinema and television, such as Freddy Krueger’s cases. A catalog of channels, some closer to moral limits than others, but all taking advantage of AI to generate three or four videos a week that accumulate thousands of visits. More garbage. Although all these cases are covered from a legal point of view, they undoubtedly have traits in common with what is known as’Slop‘, Low quality content generated by AI and that floods social networks. The least thing is that it can be distinguished whether it is artificial material or not but how the platforms themselves favor these contents with the algorithm, since The amount interests more than the quality. What is the use of True Crime. To this are added their own limits of True Crimethat since their origin in novels such as ‘in cold blood’ played with the confusion between reality and fantasy. Crime and suspense films have always been inspiring their stories in real cases, which manipulate according to dramatic interests but without accrediting their origins in reality, which perhaps also has moral gray areas that should explore. Often Documentaries are criticized True Crime for exploiting the trauma of the victims and their families and transform your suffering into a showbut the use of AI adds a new layer. Artificial intelligence feeds on documentation of real and fictitious cases, and proposes an indistinguishable amalgam of reality that can become more harmful: sensationalism twists the facts, and the AI ​​does, but in an even more perverse way. Crime ethics. The ethics that are supposed to a media traditional is blurred in these cases, submerged in a misty area where reality and fantasy are confused, but without attending ethical limits, what is worse? A story manufactured but whose characteristics are identical to a real case, or a True Crime that proves its similarities with reality, but that the hurry and lack of means lead to videos that feed the morbidity of the spectators without the need to respond to legal limits? He True Crime It continues to evolve, and not necessarily towards more reassuring areas.

How many books a month are too many books? The debate about reading as another form of extreme consumerism

by

The mixture of the need to create constant content and the search for new forms of validation has generated a new controversy in the Tik Tok literary sector. Creators cross accusations with others about the legitimacy of reading without stopping, where is the real enjoyment and if reading more or less determines the real quality as a reader. They have not reached any conclusion, but the question is on the table: how much do you have to read to read good? Readers shock. The booktoker Beautifulone of the most often of the Spanish booktokersfera, with almost 350,000 followers She was accused by another booktoker, Palomo Gamyito erroneously normalize reading dozens of books per month. According to this other Booktoker, this infernal rhythm of readings hides a much more critical reality: we must maintain that rhythm of readings to follow the crazy rhythm of launch of the great publishers, accusing many of the main creators of content about books of being spokesmen at the service of the industry. 11 tricks to dominate Tik tok What this clash hides. Gamyi is, in fact, a booktoker who instead of talking about the Latest novelties of Romantasy and literature Young adultcomments more serious novels, such as ‘The Shadow of the Wind’ or ‘The Conjure of the fools’. In addition, it combines comments from books with videos about your own love for writing. His defense of reading little but “better” also hides an ethical positioning and a claim of gourmet readings above literary fast food. Where everything is kneaded. All this happens in the BookTook digital subculture, an increasingly numerous group of users that recommends and promotes books: from recovery of classics to comments from novelties, going through tricks to read more and/or better. Many observers believe that this current our way of reading has changed and is transforming The customs of generation Z. He Hashtag that Group these users It already adds 200,000 million visualizations, enough to consider a cultural force that conditions the large publishers, who see how gender sales like Romantasy rise when recommending them Booktokers. What have the booktokers have done. Convert the accusations of Palomo Gamyi into a viral issue, of course: it has been put on the table how many books it is reasonable to read a month, all overlooked with tips and humor. It is an issue that was already commenting Since 2024so it is not new, but the video of Palomo Gamyi has brought up what this activity has to follow the editorial rhythm together. That is, a matter of creation of novel content to grow in social networks. Too many books? From this conflict two primary themes come out. The first is whether in Spain they are published Too many books: In 2024 were 89,347according to the Ministry of Culture: an increase of 2.6% compared to the previous year already levels similar to the pre-pondemic years. It is a very high figure and puts us at the head of Europebut it generates problems: a fierce competition for the care of the reader and a very short life for the news. A problem that, perhaps, compulsive readers such as beautifulbooks are helping to prolong. A validation. The other problem of the Booktoker community that hides this conflict is the search for personal validation through quantity, something similar to Likes psychology: A reaffirmation is sought through that acceptance of strangers. The mountains of read books are also a way of generating admiration and envy by a community with which tastes are shared, no matter how much reading is not very repossed and, as Gamyi complaint, does not generate a real reflection on the work, but a mere to pass pages. The discussion has not caused the blood to the river, and most of the booktokers participating in it seem to agree that each one must read what he can (and want). Which does not prevent a long and sinister shadow on such a simple and, beneficial hobby, benefit, such as reading for pleasure. They are also readers. The BookTokers They are not a promotional creation of the industry, but a spontaneous movement born in social networks (they have their equivalents in others, such as Booktubers), and they are a sign that in post-pandemic reality, there is a generalized fever by reading. Microeditorials arise consecrated to the publication of authors and projects outside the great industry, reading clubs They have ceased to be an extravagance For library mice, and books are relief from the saturation of screens we live, even in our leisure times. Conflicts like this are the least, because in the end they refer to the important thing: we like to read.

There is only one correct way to place the toilet paper. A patent ended the debate in 1891

by

We have been freeing all kinds of battles, and in some cases the response passed between disputes of each other. Among those debates there is one that never seems to disappear because both sides have it as clear. We refer to toilet paper and correct way to hang it. If we take decades to achieve a significant advance of the roll, it makes sense that the controversy has endured. The funny thing is that the answer was from the beginning. A “war” of the century and a half. Eternal dispute over How to hang up The toilet paper (with the “above” or “below” sheet) has generated opinions found, family debates and even discussions lit. Those who prefer the “OVER” method (above) Feel practical and hygienic reasons: it is easier to locate the end of the paper, reduce the risk of wall contact (and therefore with germs) and is visually more orderly. However, on the other sidewalk, the supporters of the “under” (below) appeal to a more discreet appearance and the fact that, for example, it makes it difficult for pets or children at home unwind the whole paper. An enlightened invention. However, all this controversy seems to have found an official response in an unexpected place: a document more than 130 years ago. In 2015, writer Owen Williams He rescued an image historical of Google Patents Archives which showed the patent recorded in 1891 by Seth Wheeler, nothing more and nothing less than the inventor of the perforated toilet paper. In it, it is clearly enlightened how the paper should be hung: above the roll (image below). The patent, registered by Albany Perforated Wraping Paper Company, includes unequivocal diagrams in which the paper unwinds from the front. The Wheeler patent Wheeler’s reasons. The inventor not only patented the concept of perforated paper in 1871, but, two decades later, perfected the roll design, with the intention of minimizing waste and facilitating its use without the need for complicated portarrolls. Your goal It was efficiencydo not feed endless debates: “My improved roll can be used in simpler supports,” wrote in the text of the patent. In its original conception, the paper had to fall forward to facilitate the individual tear of the perforated leaves, thus avoiding accidental unwinders or an unnecessary waste. Yes, Nokia played toilet paper before mobile Rescue science. There are more data that corroborate that the “pro-insane” are right. Science also supports this orientation for purely health reasons. According to Dr. Christian Moro explainedProfessor of Health Sciences at the Bond University, hanging the paper with the blade above reduces the risk that users touch the rear wall of the support when looking for the end of the roll, which can minimize that propagation of bacteria. Moro remembered that among the potential infection agents which can be found in the bathrooms are streptococcus, staphylococcus, E. coli and common cold viruses, all capable of transmitting through contact with contaminated surfaces. Preventing the hands from entering unnecessary contact with the wall or roll support is, therefore, a simple but effective measure to reduce the risk of infection in shared spaces. An invention … to review? Beyond the debate on how it should be placed, in recent years others have appeared around the invention. Explained the New York Times In a column that although its invention represented at the time a technical improvement with respect to previous methods (which included, attention, leaves, marine shells, sticks with sponges or even reusable ceramics), the persistence of its use reveals less a functional efficacy than a cultural resistance to abandoning the family. Here appears the Covid-19 Pandemia, at which time the toilet paper acquired An unusual prominence: Not because of its medical utility, but as a symbol of control against chaos. The Collective hysteria He led to empty shelves, ignoring that neither the supply was threatened nor the role was the most hygienic solution. And despite this, experts agree that it is far from being the cleanest or healthier option. The evidence. The Times explained That researchers in infectious diseases and colorectal health agree that the exclusive use of paper does not guarantee adequate cleaning and can, in fact, cause irritations and favor disease transmission. Among the pathogenic agents that can survive in poorly eliminated fecal remains are those germs and bacteria that we comment before and that are the cause of urinary infections. Even traces of the same were detected Coronavirus at the time in human feces. According to Dr. H. Randolph Bailey, colorectal surgeon in Houston, many anal ailments that he observes in consultation come from Excessive cleaning or with inappropriate products, such as wet wipes with irritating perfumes and chemicals. Water as a solution. Here a parallel debate opens, surely more bitter. The reason? The most hygienic method, according to many specialists, is the rinse with water, either by drums or similar. In Japan, for example, smart toilets with jets of warm water They are the normwhile in the West adoption remains marginal. The reasons are not technical or economic (today there are compact and accessible solutions), but rather cultural. Bidé rejection has been historically associated with prejudices of modest During World War IIwhen American soldiers met the bida in French brotheses, which made them “suspect” objects. The anecdote of an American tourist who confused it with a bathtub For babies illustrates to what extent the discomfort in the face of the unknown has stopped its adoption, even in France, where it was originally common. O Tallitas. In recent times a “plan C” has emerged in front of the fundamentalists of roll or water: wet wipes. The problem is that it has been accompanied by Environmental consequences. Its accumulation in sewerage networks, combined with fat and waste, has given rise to huge obstructions (known in the world Anglo as “Fatbergs“) capable of collapsing urban sanitation systems. Under that prism, instead of improving the panorama, the wipes have added a new problem to another already existing one, fed by an industry that promotes … Read more

We have just lived the first great blackout of the renewable era. The debate is now how to get the last one

by

The debate in public opinion is served for the coming weeks, at least Until the conclave arrivesat which time it will be limited to the specialized circles of the energy sector. Bloomberg analyst Javier Blas, He has baptized What happened in Spain and Portugal as “the great green blackout of the era of renewable energy.” Although the authorities have not yet offered a definitive version, the debate has intensified. Until now. The official version is still preliminary, but Red Eléctrica de España has offered a technical reconstruction of what happened. According to the latest information, the fall was not the product of a cyber attack or sabotage, but of the failure chain of several systems in a context of high renewable penetration. In a matter of seconds, about 15 gigawatts were disconnected, approximately 60% of the consumption of electric demand, due to a sharp drop in voltage, known as “voltage hole.” This type of active fall automatic protection systems that disconnect power plants and substations to avoid greater damage. According to Financial Timesthe lack of inertia – the capacity of certain infrastructure such as turbines to stabilize the network— He worsened the problem. And since Portugal partially depends on the Spanish supply, the blackout immediately extended to the entire neighboring country. Despite this, Beatriz Corredor, president of Red Electrica, He has warned that “it is not correct to relate the incident to the penetration of renewables”, defending that these technologies work stable and that the Spanish electrical system is resilient. He also pointed out that millions of data are being analyzed to clarify the exact causes of the blackout and reinforce the response protocols. Debate is reopened. A few weeks ago, the discussion in the energy sector revolved around Scheduled closure of the nuclear centrals planned for two years. However, the blackout has catalyzed a more visible ideological shock: renewable vs. nuclear. Such as has detailed eldiario.es, what happened has fed tensions among those who defend the energy transition against those who want to keep nuclear as stable support. In that same article, Jorge Sanz, the former president of the Commission for Energy Transition, has declared that one of the factors was the massive disconnection of renewables before a voltage hole. However, like has pointed out Renewable expert Xavier Cugat in his networks, Sanz has omitted a relevant fact: The existence of the Srap (Automatic protection response system), already operational and with several real and solar wind capacity gigawatts. A crucial tool that, although it did not avoid the blackout, is part of the effort to improve the technical response of renewables in these situations. But there is an unstoppable reality. According to Irenain 2024 92.5% of the new electrical power installed worldwide was renewable. That is, twelve times more renewable than nuclear, gas and coal together were installed. Clean energies are already the norm: they are cheaper, safe and in many countries, almost the only option that is being expanded. There are already concrete examples: countries like Paraguay, Iceland or Norway They work with 100% of renewable generation. The address is clear; What is at stake is how to manage this transformation without compromising system stability. What is the way? As has explained for RNE The head of the Rey Juan Carlos University, Eloy Sanz, which the Iberian Peninsula is an “energy island” with Very little international connection. Spain and Portugal need an integration much stronger With the rest of Europe to share surpluses, balance demand and strengthen system safety. To this is added the need to continue investing in storage, such as batteries, Reversible pumping plants either Green hydrogen. Finally, the development of technologies such as Synthetic inertiaalready deployed in countries such as Denmark, which simulate the stabilizing effect of old thermal plants or other strategy such as Synchronous Power Controlwhich allow renewables to also contribute to the stability of the network without the need for batteries or physical inertia flyers. Ignoring this has a price. As He has summarized Javier Blas in his column with crudeness: “The design of the network, the policies and risk analysis are not yet up to the management of an excess of renewables.” It is not an attack on clean energy, but a call of attention. The error would be to abandon renewables by a blackout, nor were fossil fuels left after Blackout New York in 1977. But we must learn. The future of energy will be renewable, but it cannot be naive or ideological.

The debate on gentlemenity actually hides a cultural break with the US

by

For the Royal Academy there is no doubt. “Gentlemanly” It is that man who behaves like a “gentleman”, with “distinction, nobility and generosity” (sic). If we talk about couples relationships, gender roles and clashes between cultures the meaning of those words becomes diffuse and their most complex implications. Good proof is that in recent days Tiktok has opened A curious debate On whether the Spaniards have forgotten how to treat women and can find a model to follow in the United States (among other countries). Tiktok’s passenger sounds, but It is not the first time that the issue gives to speak and connects with an interesting topic: the (sometimes) diffuse dividing line between the roles that marks education and those that marks machismo. And how that barrier can be seen in different ways in one society or another. “I don’t go out again with a Spaniard”. The phrase is Carolina Moura, influencer, Tiktoker and author of a video that is on its way to the 2.6 million views and in which it basically complains about the lack of “gentlemen” of the Spaniards if compared to the Americans. The piece is relevant because it has revived a debate that had already caught before In networks with other videos, such as Leslie López, a Latin one who shared a year ago A video showing their disappointment with European men. “There is no knightness here,” It coincided. @carolynnna And now the bitter ones will come to say “I do not want to go out with you” hahahaha please, to see if we learn to conquer, to respect and be more gentlemen
