There is always a disturbing friend who never speaks in the WhatsApp group. Psychology has an explanation

A notification illuminates the mobile screen: “Someone has created a group.” For some, it is almost a message of horror; For others, an infinite dose of laziness; And for a few, the promise of a new plan that begins to organize. In a matter of minutes, the chat begins to fill with greetings, memes and jokes. Someone remembers the reason for the group and then the chain of questions, photos and proposals opens. Meanwhile, a recognizable figure always appears: that of the silent one, the “merodeter” that reads but never writes. A classic of any group. But what really does that silence mean? Is it disinterest, rejection, shyness … or something more complex? A thunderous silence. With more than 3,000 million monthly active users, According to TechCrunchWhatsApp reigns as the most used messaging application on the planet. And with it came the explosion of groups: a function that was born as a practical way of coordinating plans and that today has become a social phenomenon, as useful as exhausting. Within that ecosystem the so -called “silent” appear. These types of people are characterized by conserving Ancient chats as digital relics “That” Vacation 2017 “that nobody dares to erase – or those who remain even if they never write, because going out means having to give an explanation. A gesture that, As The Guardian remembersit is perceived almost like a public desaira. The rapid dynamic of the groups. The conversations move so fast that, if you are not connected in the first minutes, You can miss 67 messages On a break, a dinner, a drunkenness and even series recommendations. It is easy to get behind. And if it becomes common, the user limits himself to reading or even ignoring, until he becomes a digital “lurker”, How to describe an article The Independent. All this leads to overload. According to a study cited by Time66% of adults in the United States say they feel overwhelmed by the amount of messages, and 42% ensure that following the rhythm of their chats resembles a “part -time work.” Some confess to reserve time on the agenda just to answer messages. Others simply ignore and prioritize: the urgent is answered, the rest is filed in the mental folder of “eternal slopes”. Experts have something to say. Psychology has begun to pay attention to this phenomenon, and the general conclusion is clear: there is no single correct way to participate in WhatsApp groups. From the point of view of psychologist Rebeca Cáceres, director of Tribeca Psychologists, the essential thing is not to pathologize silence. In interviews with Week and The Spanishinsists that each person manages these spaces differently. Silence, in many cases, is not an absence, but a conscious act of self -care: choose not to respond as a way of protecting energy and maintaining coherence with their own values. “Not responding in a group does not mean ‘it ignores me’ or ‘rejects me’. That is what you feel, not what the other expresses,” he recalls. Your approach connects with the Self -determination theory by Edward Deci and Richard Ryan: emotional well -being is sustained on autonomy and the ability to decide how to interact. For her part, psychologist Olga Albaladejo adds other nuances in statements to body and mind. Many people shut up because they fear being misunderstood. The lack of gestures, tone of voice or looks makes WhatsApp a more ambiguous space. “They think too much about how their words will be read, if they will seem frivolous, too serious or little ingenious,” he explains. In more extreme cases, after that silence, social anxiety can hide, which amplifies the fear of being judged in an environment where each message is already written the view of all. But it is not always a problem: there are also introverted people who simply prefer intimate conversations against the noise of the groups. The fomo and the spiral of silence. Professor Sarah Buglass, from the University of Nottingham Trent, It raises another explanation in The Independent. Many “merodiers” remain in groups even if they do not participate moved by the Fomo (Fear of Missing Out). That is, the fear of falling socially relevant information. Being in the group – although in silence – is a way of monitoring the conversation, maintaining the sense of belonging and not being out of future interactions. Along the same lines, the “spiral of silence” by Elisabeth Noelle-Neumann, cited in Spanish, It shows how people tend to shut up when they feel that their opinion is in a minority or can break the harmony of the group. That silence, over time, is consolidated and ends up becoming a fixed role. The problem is that this behavior is not always interpreted correctly. For those who expect an answer, the lack of interaction can become a mirror of insecurities: feel ignored, little valued or even despised. “The silence, although legitimate, is not neutral,” Cáceres warns in Spanish. That is why he recommends that, if the lack of uncomfortable response, the healthiest is not to insist in public, but to open a private, honest and unjustial conversation. And what happens if you should be? Here we enter the obligations and these work groups, created for professional purposes, which end up becoming hybrid spaces where congratulations, jokes and memes are mixed. This ambiguity generates discomfort in some participants. Cáceres insists on week magazine in which the solution involves establishing clear rules: use schedules, type of allowed messages and the decision to use a personal or corporate number. Only with explicit agreements can we talk about commitments and expectations; Without them, demanding immediate response is meaningless. Resist hyperconnection without losing links. Silence in WhatsApp can also be seen as an act of resistance. The writer Richard Seymour, In The Guardianit relates it to the “right not to say anything” of the philosopher Gilles Deleuze. In a culture that rewards hyperconnection and immediate response, refusing to participate is a way to reaffirm control over time. However, group chats also … Read more

The countries with more nuclear bombs in 2025, gathered in this graph with two protagonists: China and India

In January 2007, the Watch of the Last Judgment remained at five minutes of the devastation. In January this year, I was barely 89 seconds of midnight. This clock represents, symbolically, if we are close to a nuclear devastation, and the data of 2025 was the most bleak in its 78 to those of history. Although the United States and Russia continue to dismantle nuclear arsenal, they are still the powers that more atomic bombs have. However, China is putting the batteries And another country wants to demonstrate that it has no qualms about arming: India. And this graph perfectly represents the situation of world nuclear arsenal in 2025. The photo in 2025. Prepared by Visual Capitalist From data from the Stockholm International Peace Research Institute, or Sipriin the graph we can eloquently see the state of the nuclear arsenal until January this year. The United States and Russia evidently dominated The world nuclear arsenal during the Cold War and, although they are still the two nations that have the most ojas in their possession, that arsenal has been diminishing. During the last months, it is estimated that the United States would have discharged eight eyes while Russia would have ‘retired’ another 71. France and the United Kingdom, which recently confirmed actions to combine their arsenalThey are maintained, like Pakistan, Israel and a North Korea that has a secret arsenal, but with an estimated 50 heads. As can be seen in the image, the US and Russia continue to dominate the segment incontestable, but there is a third country that, also evident, is taking leaps and accelerated to get a good arsenal. China. About a year ago, A SIPRI report He surprised everyone by showing that China was increasing its nuclear arsenal at a stupid speed. Now is in a position that allows Ask for both the US and its allies With nuclear arsenal and that Chinese expansion has been the perfect excuse for the “Rearme” that the Pentagon has asked for. Of the 500 estimated heads of China in 2024, we went to 600, which represents 20% more in a few months that allows to see in an evident way that the Asian giant has taken the renewal of its forces seriously. Nuclear weapons investment is not the only thing we have witnessed, since China boasts electromagnetic catapults of his new warships, of latest generationof New combat fighters and Even a huge poaching plane. India puts the batteries. Despite those 600 heads, it is estimated that they have less than 30 strategically deployed (those that are ready to launch). The United States and Russia have less than 2,000 deployed, France has almost all lists to launch and the United Kingdom half, more or less. The one estimated that it has zero deployed bombs is India, but the new SIPRI report shows that the country’s nuclear investment is paying off. In fact, and without knowing really how things are going in North Koreait would be the only country that has increased its arsenal, adding another eight heads in recent months. They have reached 180 and arrive just at a time of high voltage in the Indo-Pacific region, with continuous demonstrations of force As the other big in the contest does, China. New generation of bombs. The current situation is … complex. With the invasion of Russia to Ukraine the Fear of nuclear war. With the recent conflict between Israel and its neighbors, Those drums have sounded again And, meanwhile, China promotes pacts not to attack first with nuclear arsenal while the treaty expiration is approaching START III which limited the amount of strategic weapons deployed by nuclear powers. Russia se He disconnected of that treaty, directly, in 2022. We will see in a few years how graphics of this type evolve, since France confirmed In 2024 a program to produce Nuclear bombs New generation and more recently they bet on new Actions to consolidate your role as one of the pillars of nuclear deterrence in the West, something that blocks with the Objectives of Rearme launched by Europe.

It is the result of a whim of nature

In Spain there are long streets, very long streets and then there is the Gran Vía de la Mangain the Region of Murcia, which more than for relaxing walks is designed for demanding marathons. The figures speak for themselves. From the entrance of the manga to the area of ​​the Venezuela Beach The vial measures around 19 km, a long asphalt tongue that allows it to be often at the head of the largest streets in Spain, since There are those who assign To the Gran Vía de les Corts Catalanes, one of the most important roads in Barcelona but measures 13 km. Streets worthy of a background corridor. The longest street? There are no official and recent studies that delve into the subject, but when it indicates long streets (extra), the finger is usually targeted to the Gran Vía de la Manga, in the manga of the Mar Menor. Of course its measures attract attention. Between the entrance of the manga and the Veneziola area it measures about 19 kilometers, which has allowed it to emerge in studies such as the one last year to the theme the real estate portal Idealistic. If we can enjoy it, it is largely because of the natural whim of manga, A coastal cord That part of Cabo de Palos and naturally separates the Laguna del Mar Menor and separates it from the Mediterranean. The strip is 20 km east of San Javier already 75 southeast of the city of Murcia. “It is a unique natural resource in Europe, it measures from north to south almost 24 km and from east to west less than one in its widest part,” Precise the Manga Consortiuman organism driven by the consistories of Cartagena and San Javier precisely to attend the area. Is it a disputed position? Yes. The Gran Vía de la Manga crosses a residential area bathed by the waters of the Mar Menor, but there are those who consider that what we are talking about is from urban streets the most extensive is another: the Gran Vía de les Corts Catalanesone of the arteries of Barcelona and that lasts 13 km. So long is that at least in 2015 it was calculated that throughout its route he added 689 portals. With those figures the company JLL or the operator Advancement It has been considered the kilometer street of the country, although making a wink in their studies to the Murcian road, which takes several kilometers to the Catalan. Are the only streets that stand out? No. Leaving the extensive highway map and highways aside, Spain can boast a street with some particularly extensive or populated roads, such as Calle Valéncia, in Barcelona, ​​with approximately 569 portals, According to idealist. In its listing, Alcalá Street, in Madrid, with 10.5 km and 544 portals or Azalea de Alcobendas, also in the province of Madrid and is around 480 portals. More or less they have Aragó Streetin Barcelona. And in other countries? The Murcia and Catalan road are extensive. Very extensive. When an international perspective is adopted, they cease to be so striking. Although the key is to be considered exactly “street”, the 19 km from the Gran Vía de la Manga They know little If compared, for example, with Western Avenue, in Chicago, which passes from 35 km; or Sunset Boulevar, in Los Angeles, and Broadway (New York), which exceed 30 km. Yeah We consulted the Guinness bookits pages collect an equally striking case, although it describes it as a “longest straight road”: a 240 km road in Saudi Arabia built by the King Fahd. Maybe The most striking case However, Yonge Street, in Toronto, indicated for some time, the Guinness as the most extensive street in the world with a surprising length, which actually responded to a calculation error: its technicians added the length of the vual to the one of the Ontario Highway 11.

This Barcelona bus has been working with a fuel that we all produce: our excrements

A bus of line V3 has been circulating through the streets of Barcelona that has been operating exclusively with a renewable fuel generated from what we least imagine: human waste. And best of all, the experiment has been considered a success. A project that has managed to evolve. This project was baptized as’Nimbus‘, and is the result of a collaboration agreement between The local water management company VeoliaMetropolitan Transport of Barcelona (TMB) and the Autonomous University of Barcelona (UAB). Together they have turned the concept of circular economy into something very tangible: transform the sludge of wastewater into biomethane for public transport. Five years later, and with good results in the hand, the project is ready to move on to the next level and start with large -scale production thanks to European funds. The ultimate goal is to make the production of this fuel based on the solid waste of the city to end in the deposits of the buses themselves in the future that is not very distant. This creates this fuel. The heart of this innovation It is found in the purification of Baix Llobregatone of the largest in Europe. Every day, this plant processes about 400,000 cubic meters of wastewater. While 95% of the water is regenerated for agricultural or urban uses, the remaining solid waste, known as sludge, usually end as dry material for agriculture. The Nimbus project has given it a new purpose. Using an innovative process, researchers have managed to transform four cubic meters of mud per hour into high purity biomethane. This gas is pure enough to be used in vehicles with natural gas engines without any modification. The secret is to refine the initial biogas. Initially, gas contains 65% methane and 35% carbon dioxide. Instead of separating gases, Veolia’s team Combine carbon dioxide with hydrogen that is obtained in renewable sources. In this way, almost all the biomás becomes biomethane, making the resulting fuel emit so much carbon dioxide. A fuel responsible with the environment. The figures that result from this first phase have shown that this biomethane works very well. It emits 80% less carbon dioxide than traditional natural gas and complies with strict regulations of EU euro VI emissionsalthough it produces nitrogen oxide to very small amounts. An alternative to electric buses. Right now, Barcelona’s periphery routes need a bus that has a high passenger capacity and greater autonomy. This is something that electric buses cannot offer today, but biomethane, maintaining the reduction in the emission of carbon dioxide. The future: more buses and production at an industrial scale. After five years of success, the Nimbus experiment gave way to a new phase: the project Sempre-Bio. The objective is now climbing production, going from generating biomethane for a bus line to do it for two. For this they have a budget of more than eleven million dollars, with financing from the European Union. As detailed in the project, with this budget they will “reduce the investment and exploitation costs of biomethane production plants and expand the biomethane production potential through new routes of waste valorization.” Many projects to find the ideal fuel. Synthetic fuel It is one of the great research results for finding an alternative to natural oil. One of the examples is The e-diéselwhich is based on “water and air” for conventional engines, or even Toyota He already works with hydrogen to turn it into an alternative To keep the combustion engine. But the reality is that right now combustion cars are in danger of extinction. Electric cars They don’t stop growingand the Chinese market Not stop driving this sector on other continents Like Europe.

The last extreme idea in beer fermentation has nothing to do with alcohol. It has to do with murderous bees

The human being has been fermenting beer since time. In spite of this there is always a place for innovation and, probably the “recipe” created by microbiologists from the University of Cardiff, in Wales, is not precedent in the history of mankind. Bee-r. A team of researchers He has created beer using a type of yeast found in the so -called “Killer Bees of Namibia.” The yeast in question (Saccharomyces cerevisiae) It was extracted from specimens of this bee that had died due to natural causes, and then used for the fermentation process from which beer is created. The origin of the idea was on the visit of the British team to the University of Namibia. During the trip, they explain from the Unviersidad de Cardiff, the team was interested in these bees. “When we arrive back to Cardiff, we use the isolated yeast from the murderous bees, next to yeast extracted from Welsh bees, to create several beer remittances,” Les Baillie points outProfessor of Microbiology at the Welsh Center. The “murderous bees”. The so -called “murderous bees” are also known by the least threatening name of Africanized holiferous bees. It is a hybrid subspecies of the common bee (Apis Mellifera), which results from the hybridization of other subspecies of this common insect. The Denomination of Killer is due to aggressiveness Of these bees with whom they consider a threat: these bees attack in large numbers which increases the risk of encounters that are fatal. What do you know? The yeast S. Cerevisiae is (as its name suggests) a yeast commonly used In the manufacture of beer so, regardless of the singular of its origin, beer would not be special. However, we will not have to contrast that fact by our own means. This beer, They explain its creatorsseeks to combine the knowledge of the equipment in microbiology to bring it to products related to bees “to produce something unique.” Now, it’s time to climb the process, looking for some winery willing to take this “recipe” to the market. This could also serve to economically promote this type of research. “Our killer beer is a complementary project for our Pharmabees study. Our study is showing how honey, wax and other bees products can play a role in solving some of the greatest world challenges, including resistance to antibiotics and superbacteria” Baillie added. Pharmabees. Within the Pharmabees project, various actions focused on exploring, for example, how the pollination of certain plants can help us in the fight against superbacteria are registered. To do this, the team installed various hives in the university environment, accompanied by specific plants that, in principle, could lead to bees to create new types of honey and other products. The idea highlights the importance of these insects, not only because of their role in ecosystems but also because of their potential capacity to help synthesize certain compounds. Compounds that, who knows, could one day use for the most surprising purposes.

An app to go to strangers ceremonies

Two men suited sneak into a wedding. No one knows them, but there they are: providing with champagne, laughing with the guests and looking to flirt on the dance floor. It is one of the first scenes of Wedding wedding, The comedy starring Owen Wilson and Vince Vaughn in which the unthinkable played in play: infiltrate others. What looked like an absurd fantasy today begins to happen really. In France, it is no longer necessary to invent excuses or disguise yourself as a distant cousin: it is enough to download an application, pay entrance and sit at the wedding of complete strangers. This has come Invitin. The app that converts love into an entrance ticket. Created this year by the entrepreneur Katia Lekarski, exmodel and founder of Digital Platforms of Child Design, Invitin functions as a Wedding Airbnb. Couples publish their celebration, set the price per person and those interested buy their seat. The company stays with a 15%commission. As explained to The Guardianthe idea arose when their five -year -old daughter asked him why they never invited them to weddings. “I thought: what if you could pay the entrance to a wedding just like you pay a guided tour or dinner with strangers?” He said. Anyone enters. As they detail on your websitethe bride and groom can review the profiles of the attendees and they must sign a code of conduct: arrive punctual, dress elegant, not to drink in excess and not publish photos without authorization. The concept is not entirely new. In India, the company Join My Wedding It already connects foreign tourists with local couples who celebrate traditional links, under the motto: “You have not been in India until you have attended an Indian wedding“. There, attending a ceremony can cost about $ 250 per person and is sold as a cultural experience. Invitin takes that logic, but adapts it to the European context: it is not about offering folklore to visitors, but that French couples finance part of their wedding by making it a shared event. The first wedding with unknown payment. The pioneers were Jennifer, 48 -year -old actress, and Paulo, exatleta, 50, who married this August in a country house near Paris. With an 18 -month -old son and after getting to get to an appointment app, they decided to try Invitin after discovering it at a bridal fair. Its history, Collection by The Guardianhe has detailed that they sold five tickets to 130 euros each, who joined their 80 family and friends. The new “payment guests” enjoyed the whole day: votes in the garden, cocktail with live music, formal dinner (with vegetarian option, since the bride does not eat meat) and the posterior party. How much is intimacy? According to Jennifer, money is almost secondary. “It helps to cover decoration or dress, but we do it because we are outgoing and we think it could be fun to share. In addition, we have many more single friends than single men, so this helps to balance things a bit,” Daily Mail explained. Buyers – or guests – also live it as an opportunity. Laurène, 29, He has confessed to The Guardian that I saw it as “a way of living a different wedding and traditions” in a happy atmosphere. However, the model is not exempt from controversy. In Daily Mailsome readers described the practice of “shabby”, remembering that the word “guest” loses all its meaning if it implies paying. In fact, they remember a case of a New York couple who asked for $ 333 per person to friends and family to marry the Cathedral of San Patricio. The outcome was with 80% of the guests refusing to attend. Lekarski defends, however, that it is a cultural and experiential phenomenon, not just financial. Figaro Gather couples testimonies They see it as an opportunity to replace absent guests, expand the list without shooting costs or even creating new friends. A Russian user has summarized it thus: “Attending French weddings will allow me to better understand their traditions and culture.” The transformation to the show. The phenomenon does not arise from nothing. In the last decade, weddings have become Macro events. As my partner has pointed out in Xatakathere is an authentic “fever” for watching weddings in social networks, with videos that accumulate millions of views in Tiktok and Instagram. The bride and groom are looking for viral moments: theatrical entries, fireworks, rehearsed choreographies. At the same time, the costs shoot. In Spain a link can cost what an average worker earns in a whole year. The tendency to fatten the invoice includes eccentric ideas: Tattooists in the Convitevirtual reality cabins, thematic photocalls. Even controversial restrictions are imposed, as “without alcohol” weddings For fashion Healthyto despair of the guests. In that context, Invitin is almost a logical consequence: if weddings are already lived as a show and are unassumable for many couples, why not turn them into an event shared with payment tickets? From the Airbnb sofa to the altar. Today the app adds only hundreds of users and a few confirmed links, but its founder already dreams of expanding to the US and European tourism. And it would not be strange if he did it: after all, we have already normalized sleeping in the bed of a stranger with Airbnb or dinner at someone’s house we don’t know through Eatwith. Logic is the same: transform the intimate in payment experience. First was hospitality, then the family table and now the wedding. Invitin does not invent anything, simply pushes a border more: if we rent the living room and bed, why not also the “yes, I want”? The question is if we will see weddings in Spain soon with payment entry, in a country where the links are especially expensive and the banquet is almost sacred. Because, for now, Invitin is a French experiment, but its incentives – a budget and convert an intimate rite into show – are universal. Epilogue. In Wedding weddingthe protagonists … Read more

Those who make poop on the planes

We live surrounded by bacteria. Many are inside us And nothing happens, although there is others that are more treacherous. Above all, there are superbacteria. They are the ones who have Developed resistance to antibiotics And they are extremely difficult to eradicate. The World Health Organization itself has cataloged them as one of the greatest health threats, but there is something that can help us end them. Make peanut on the plane. AMR. They are the acronym in English of “Antimicrobial resistance”, Something that was found when antibiotics began more common in the 50s and that has accelerated in recent years. Excessive use And sometimes, inadequate of these medicationsas well as The sale without recipehas made bacteria rise level and be more resistant. And the worst part is that they are not located, but that they travel all over the world due to the trade of animals, food and the trips we can do by plane. Air pollution also helps transport resistant bacteria. Impact. The most common pathogens are Staphylococcus aureus, E. coli, Klebsiella pneumoniae, Acinetobacter Baumannii or multirresistant tuberculosis, and it is estimated that they currently produce more than one million direct deaths every year. For A population of more than 8,000 million peopleit may not seem too much, but already You talk of about 39 million direct annual deaths for 2050 due to these superbacteria. They put transplants at risk, they are a threat to food security, make treatments difficult and hospital stays increase. And, in addition to direct deaths, It is expected An increase in health costs of about 160,000 million dollars annually. The analysis. We have commented that traveling by plane makes it easier for these resistant microorganisms to move from place, being able to contaminate totally new groups. It is something we have seen with Pandemics like Covid-19and that migration of superbacteria by plane has been the protagonist in a study Prepared by the National Science Agency of Australia, in collaboration with the University of Xiamen, the University of Australia del Sur and the Technological University of Michigan. Specifically, they analyzed wastewater from the bathrooms of 44 international flights that arrived in Australia from nine countries: 18 came from India. 14 of the United Kingdom. Six from Germany. The rest were a flight from: France, United Arab Emirates, Türkiye, South Africa, Japan and Indonesia. Aircraft excrement extraction system Differences. The researchers detected nine priority and superbacteria pathogens, some of them resistant to multiple drugs. Of the nine, five were in the fecal waters of the 44 flights, while a gene that confers resistance to last resort antibiotics was detected in 17 flight. This is the most resistant to the most powerful antibiotic treatments. Nicholas Ashbolt, a microbiologist at the University of Australia del Sur, commented that “flights from Asia, in particular from India, showed higher concentrations of genes of genes from Antibiotic resistance Compared to flights from Europe and the United Kingdom. ”Yawen Liu, a researcher at the University of Xianmen, ensures that these differences can reflect variations in the use of antibiotics, water health, population density and public health policies of each region. Peanut. Now, why is it so important to urinate or defecate on a plane to fight the superbacteria? Warish Ahmed, the main scientist of the University of Australia, comments that “the wastewater of the aircraft captures microbial signatures of passengers from different continents, offering a non -invasive and profitable form of monitoring threats such as AMR’s.” In addition, in the study they have not limited themselves to measuring the presence of superbacteria in the wastewater of the airplanes, but to find out If the disinfectants used in the bathrooms affect AMR. The results showed that nucleic acids remained stable up to 24 hours, even in the presence of strong disinfectants. This points to the importance of analysis of the depositions in the aircraft for surveillance purposes. Critical. “Wastewater monitoring of aircraft could complement existing public health systems, providing early alerts on the emerging threat of superbacteria,” says Ashbolt, and the study concludes by pointing out that this mere proof of concept has great potential in the real world to convert the bathrooms of the aircraft into an early warning system that allows to better manage the better public health. I recognize that I have made a multitude of flights and, whenever I have been able, I have avoided using the toilet of the plane because it seems uncomfortable. But, if I have no choice, in my next flight I will lite my blanket and I will do my things thinking that I am doing a favor to science.

Labubu Humanity Bags are being small. So its creator already knows how to sell even more

Labubu have become a global phenomenon. In China alone, for 2024, they reached sales for about 355 million euros and, since then, their figures in the rest of the world They grow at a rhythm of 480%. To Spain too The fever arrived: The stores They ran out of stock and many buyers have had to resort to Wallapop or Vind, with the consequent Risk of falsifications. Pop Mart, the manufacturer of the stuffed animals, He has shot in the stock market After affirming the CEO Wang NO that its initial forecast of reaching 2.8 billion dollars in sales for this year can grow 50% to 3,580 million, something that, says “would be quite easy.” He would be able to double the income of 2024. And they have explained how they plan to do it: launching the “Mini Labubu“ From the bag to the mobile. With their rabbit ears and a very sinister smile, the labubu have conquered bags and backpacks of their buyers, after being popularized by influencers like Lisa, from the K-Pop Blackpink groupDua Lipa, Madonna, David Beckham or Kim Kardashian. Now Pop Mart wants to conquer something much more common and transversal than a bag: the smartphone. As the company explained, the Mini Labubu can be placed on phones, and will not take them to launch them. It will happen this week. The ‘Sonny Angel’ taught the way. The mobile accessories market is huge, but none explains so well the step that is going to give Pop Mart with the Mini Labubu like the ”Sonny Angel‘, those little “plastic angels” that after being created in 2004, are now glued to many mobile and even laptops of very young people from Spain after being a viral phenomenon in Tiktok. The key was the version ‘Hipper‘, designed to fit with the mobile and corners and frames of the screens and popularized by celebrities such as Rosaría or Victoria Beckham. And they took steps such as collaborating with covers of covers such as Casetify that show Pop Mart where sales can continue to grow once they launch the reduced size labubu. In fact, They already collaborate With brands such as Disney, DC, Marvel, Minions, Capcom, Garfield, etc. As explained in The Economist, China is now “Cool”and has everything to conquer Europe. Without supplying, but with a plan. Wang said that it is very optimistic for the company’s performance “in foreign markets”, and believes that “there is a very wide space for growth”, predicting that the sales of North America and Pacific Asia will match those of China in 2024. The problem is that Labubus’s production does not give to meet demand. This explains average resale prices of $ 121 (and up to 240 euros), compared to the 30 dollars that are officially sold. It is the same problem that Xiaomi also faces in China with The resale of su7but they are working on expanding the production capacity, and Yuan Junjie, president of the Pop Supply Chain Center Mart, states that produce 10 times more than in the same period last yearwhich translates into 30 million units per month. They plan to continue improving, with two new factories abroad and two in China. At the moment they have benefited from Getting with Labubus is an art.

There was a day that Volkswagen wanted to have “the Bentley of the town.” It went wrong

If something has shown us the history of the car is that it is completely irrational, extremely competitive and very conservative. The electric car is demonstrating it clearly. The number of brands has triggered and China wants to make a foothold on European soil. The reality is that Only Tesla seems to have found the way Correct and China is moving in Europe … but with Combustion engines. That conservatism is not new. Raising a brand from scratch is only possible with a huge economic effortsustained and almost blind for years and years (like Tesla)with the help of state media (as Xiaomi and its association with one of the national Chinese car companies). But it is also almost impossible to change the perception that the client has of you. Winning to the client and ascending on the ranks of the market can take decades. A good example is Hyundai and Kia that have some of the best -selling cars In our country but they had to start earning market share selling cars much cheaper than those of the competition. But rapid movements, those who want to position a brand in a higher segment almost from nowhere or those that seek to compete with premium brands with a model that equals features but also in price is generally a call to failure. There is a good handful of examples and the Volkswagen Phaeton is undoubtedly one of the most representative. History of a failure Luckily for those who like cars and unfortunately from manufacturers, the purchase of a car is irrational. It has an inevitable part of aesthetic taste but also for quality perception, affinity with the brand and construction of an image and a history based on the past. That makes, for example, Renault fails with Vel satisf either Avantime Although they were very good vehicles that tried position yourself above the generalists. Nor has Stellantis (and before PSA) achieved return to DS to your luxury past Despite the multiple attempts. And something similar happened to Volkswagen Phaeton. By order of Ferdinand Piëch, then president of the Volkswagen Group, the Germans wanted to assault the premium market with a Berlina that was called “The Bentley of the People”. The intention was to stick with the Mercedes S, BMW 7 series and, curiously for being part of the group, with the Audi A8. The bet was so strong that the possibility to match (or improve) in equipment and materials to its rivals with a more adjusted price was not even tan. It was directly to resemble all fronts (also in price) and in the executives of Volkswagen they took a tortazo. In fact, the Volkswagen Phaeton Not even was a version of Audi A8. Yes, he shared some aluminum panels with the Berlina of the four hoops, as explained in Km77 In the early 2000s, but for development it departed from a blank sheet and even The Volkswagen Dresde factory was builtknown for their Glass structure and for being the one that, discontinued the Phaeton, covers the complete electrical models of the company. In that assault on the heavens, the Phaeton was sold above 66,000 euros for what the German triad looked from you. A Audi A8 It was sold at that time slightly below 69,000 euros. A BMW 7 series It started from 67,500 euros. He Mercedes S Yes it was significantly more expensive, starting from more than 71,000 euros. In those early years of the new century, all German luxury Berlins shared two things: they all had versions above 120,000 euros. And they all had gigantic engines. And the Volkswagen Phaeton was not going to be less. Its most “small” engine was already a V6 in diesel and gasoline versions. From there, it could only be dreaming. Volkswagen’s bet was also sold with a V8 4.2 gasoline, the famous V10 5.0 TDI and an endless W12 6.0 of gasoline that was sold with 420 and 450 hp versions. The average consumption of the latter was around (with the homologations of that time) 14.5 liters/100 km on average. And of equipment, the Phaeton was not badly served: heating seats, electric with memory and massage, bi-xenon headlights, four-zone heshlyzizer, indoor in the skin topped with wood and the possibility of replacing the rear seats with two sidewalks to improve comfort. Developing the car, therefore, was not going to be easy. At least this is attesting to 1,100 million euros that, according to Autoweekthe Germans invested in their development. From Automotive NewsHowever, they raise the figure to 2,000 million euros. But despite the expensive development and the good of the product, selling the Phaeton was not simple either. To the point that, according to this last medium, the Germans lost 28,101 euros for each unit sold. Keep in mind that the company had made a effort huge in machinery, employees and a new factory (The Dresden crystal plant) To launch a car that would meet the quality of a vehicle of its price range. It is said that Ferdinand Piëch delivered a series of unnegotiable requirements to put the car on the street among which was the ability to maintain the interior temperature at 22ºC circulating in a sustained way at 300 km/h with an exterior temperature of 50ºC. And all despite the car was limited to 250 km/h. Only for overestimating the capabilities of the car and that there was no open door to the client’s disappointment. But the market did not respond despite the fact that Volkswagen reached up to 100 patents during its development. Estimates that aimed at 20,000 units sold a year were impossible to meet. Even as the years passed. Because during the decade and a half that the car was on sale only 84,253 units were sold. Volkswagen’s most optimistic forecasts, collect in DiariomotorThey could exceed 35,000 units sold. And, as exceed, the 50,000 cars sold. Seeing one of those people’s bentley was not as complicated as seeing a true Bentley but of course it … Read more
