Adidas has managed to get all of Spain to wear the National Team shirt. It has also managed to get almost no one to buy it from Adidas

I’m sorry I can’t link it but the other day I read a tweet that said something like: “In these moments of extreme polarization, there is only one thing that unites all of Spain: the fake National Team shirt.” In cascade, there were the answers. One after another, fans fed up with the abusive price of football shirts, an accessory that It is already transversal to the sport itself but for which many are not willing to pay more (much more) than 100 euros for a product that you can have at home for just over 20 euros. At the gates of a World Cup, with a Spanish team that excites and a shirt that has had a deep impact since its presentation, the team’s second kit, the white one, can already be seen everywhere. And, of course, it’s not always official. It complicates your month According to Bankinter datathe median salary in Spain for a man was about 26,000 euros in 2024, the latest data published. That of women was just over 22,000 euros. That leaves us with a gross salary, of course, in 14 payments of just over 1,800 euros for them and less than 1,600 euros for women. With that salary, whoever wants to buy the official shirt of the Spanish National Team, replicating all its details, will be dedicating around 15% of the money that enters their account at the end of the month. Official Authentic T-shirt: 150 euros Player name: 20 euros FIFA patch: 10 euros Euro champion patch: 7 euros The accounts come out quickly and easily: 187 euros It is what it costs to wear the same shirt with which Lamine Yamal will take the field in Atlanta (United States) on June 15 at 6:00 p.m. (peninsular time) to face Cape Verde. That, of course, if you manage to get your hands on any of the t-shirts that They have already flown from the Adidas website. For much less, just 23 euros, you can have a replica at home in less than two weeks. It’s not that I asked one of the many in my close circle who have already gotten one. There is simply a website that ranks ahead of Adidas itself on Google. The German company says that “Spain’s away shirt pays tribute to this country’s incredible literary legacy, with intricate prints inspired by manuscripts, a nod to the cultural depth of the Spanish language that connects culture and football.” Let’s say that that other website does not offer such a literary description but what is certain is that there must be plenty of clients. The (pen)last example The second Adidas kit has highlighted the rise of fake t-shirts replicas and the enormous popularity they have garnered in recent years. Sid Lowea British sports journalist welcomed by the Asturian community, echoed this article in Digital Freedom in which the enormous popularity of Spain’s second shirt is mentioned. The one that no one seems to have paid at the price that Adidas lists on its website. Click on the image to go to the original tweet The responses criticizing the high price of the official set and the defense of getting one, let’s say, less official are repeated one after another. Click on the image to go to the original tweet The answers seem to concentrate each and every one of the issues surrounding the underworld that football shirts have become in recent years. Those of us who have dressed Saturdays, Sundays and summer holidays in football shirts and shirts know that replicas do not have the same feel as an original. No? Sure? Without a doubt, it looks a lot like him. It’s something I’ve known from conversations with friends and because… well, he who is free from sin… An example: Real Madrid shirt 99/00. Pushed by the nostalgia effect dosmilerothe aftershocks multiplied their presence in the streets. To the point that Adidas took advantage of the pull to reissue them and make good money. At least, to get mine and that of enough fans who spend our 110 euros to buy a shirt with more than a quarter of a century of history. In my case it was because I wanted to have the shirt with which Raúl dribbled past Santiago Cañizares to score Real Madrid’s third goal in the Champions League Final in Paris. He wanted “the one on Eighth”, the black one. Because the white one had already been given to me a few months before and this one was not entirely true. And, despite this, I had to go to the closet to rescue the shirt that I was wearing when I was eight years old and had an R. Carlos (3) on the back to certify that it did not have the same shiny patina that the official one had. Nor was the stitching of the shield the same, of course. No, it wasn’t the same, but it was almost identical.. And that is enough for many, many of us to wear the shirt of our childhood on the street again. It doesn’t matter if the shirt is from Raúl’s best years, Djalminha wearing Feiraco on the chest of Deportivo de la Coruña or Maradona carrying Buitoni to levels of popularity they never imagined. They all share a single code: they are fashionable. So much so that Adidas has not hesitated to reissue iconic designs from the nineties and 2000s. Without going any further and taking advantage of the return of the World Cup to the United States, For 110 euros you can dress like Clemente’s Spain in 1994. At least, the Germans have had the detail of not reissuing the second kit, forever anchored in a Luis Enrique bloodied. The football shirt phenomenon has become a transversal fashion that transcends genres, decades and teams. They are there when you go to buy bread, when you have a party with friends and when you go to the summer music festival. That has also created a … Read more

“Slaughterbots” are no longer science fiction in Ukraine. Russians wear masks to avoid the drone that aims at their heads

by

A few years before the start of the war in Ukraine, a Berkeley computer science professor presented at the UN a short called “Slaughterbots”a piece where small drones with facial recognition chased people autonomously. Many saw it then as another technological exaggeration in the style of the Black Mirror series. A few years later the short… has fallen short. Drones that search for tanks, search for people. For much of the Ukrainian war, drones were seen as a support weapon intended to destroy armor, correct artillery fire or monitor enemy movements. That phase has gone disappearing quickly. What is now emerging is something much more disturbing: cheap drones, produced by the millions, designed specifically to hunt down and kill soldiers. individually. They counted in Forbes that the Russian military channels themselves they are warning of Ukrainian FPVs equipped with thermal vision, reconnaissance systems and munitions capable of firing explosive projectiles at a distance directly against a human body. The detail that is generating the most fear is not the weapon itself, but the possibility that these drones are already learning to identify Where to hit to maximize lethality. The idea of ​​small autonomous devices “hunting” specific people no longer belongs to technological dystopias or viral YouTube videos: it is beginning to form part of the front line’s routine. A gigantic aerial hunting area. The most profound consequence of this revolution is that huge parts of the front have been transformed in “kill zones”those corridors where any human movement can be detected and destroyed from the air in a matter of minutes. Ukraine has especially perfected this model around cities like Kostyantynivka or Chasiv Yarwhere small Russian groups are identified long before approaching the defensive lines. The result has been devastating for classical Russian doctrines: large armored columns and mechanized assaults have become too visible and vulnerable. In response, Moscow is trying to create their own “drone racers”infiltrating small teams of operators hiding in basements, destroyed buildings or tree lines to build temporary bubbles of local air dominance. In other words, war is no longer just about controlling the terrain, it is about controlling the sky just a few meters above each soldier’s head. The true technological leap. The most important thing about these new systems is not the size of the explosive charge, but intelligence that begins to guide them. Many Ukrainian FPVs already integrate autonomy modules capable of continuing the attack even when the operator loses signal due to electronic interference. Western companies and civilian developers have created relatively inexpensive kits that turn commercial drones into smart munitions capable of automatically locking on and pursuing targets. Until recently, that autonomy was mainly used against vehicles; now the focus shifts to the infantry. Some models use EFP loadsformed explosive projectiles that do not need to hit directly to penetrate protection and kill the target from a distance. That eliminates many of the defenses improvised measures that had proliferated on the front, from metal nets even the famous Russian “turtle tanks”. The problem for soldiers is that hiding no longer guarantees survival: the drone can continue observing, wait for the exact moment and attack when it detects vulnerability. “Slaughterbots” stopped seeming over the top. We said it at the beginning, in 2017 Professor Stuart Russell launched the short film “Slaughterbots” as a warning about autonomous drones with facial recognition capable of murdering specific people. At the time it seemed like a futuristic hype designed to open ethical debates about military artificial intelligence. Nine years later, the parallels are beginning to be uncomfortable even for those fighting on the ground. Russian soldiers develop countermeasures that seem straight out of a science fiction movie: using masks to confuse recognition systems, throwing helmets as decoys, hiding their heads behind obstacles or remaining completely still to avoid thermal tracking. Obsession reflects a huge psychological change. For centuries, a soldier could attempt to protect himself from enemy fire using cover, armor, or distance. Many fighters now feel that there is a camera constantly watching them from above, capable of deciding when to attack and possibly where to do it to ensure death. The industrial and algorithmic battle. The great Russian fear is that Ukraine will manage to combine mass production, autonomy and precision on an unprecedented scale. kyiv aims to manufacture millions of FPVs a year, and that completely changes the mathematics of combat. Whether a relatively cheap drone can chase soldiers with hit rates close to 80%human wear and tear begins to take on industrial dimensions. That is why Russia is desperately trying to build its own drone racersdeploy interceptors and saturate local airspace before moving larger troops. However, Ukraine maintains an advantage in both quantity and technological sophistication, especially in optics, autonomous navigation and aerial interception. What is being seen in the Donbas is not simply a tactical evolution of drone warfare: it is rather the birth of a new form of combat where thousands of semi-autonomous machines continually compete to detect, pursue and eliminate individual human beings. And the most disturbing thing is that this transformation is just beginning.

This space company has designed the suit for astronauts that you would also want to wear on the street

by

The private space company Vast has presented at the 46th Space Symposium the suits that its team will wear both in training on Earth and in missions in space. These are aesthetically appealing clothes, but above all they have been manufactured with careful consideration of the needs of astronauts. on the International Space Station. Thus, the aim is to facilitate both their movements and their ability to work. Both with and without gravity. As explained in a Vast statement former astronaut and company advisor Megan McArthur, in space the body takes on positions that it does not take on Earth. Additionally, when working in microgravity, it is necessary to always have your hands free and tools within reach. They may be necessary at any time. For this reason, spacesuits must put comfort and operability above all things. Pockets, zippers and hooks. Vast’s spacesuit consists of two pieces, which can be worn separately or as a jumpsuit, joining both parts with a zipper. It has a multitude of pockets, like cargo pants. The main difference with any garment with pockets that can be worn on Earth is that each of them is intentionally placed to squeeze out their use in microgravity. They are right where they are needed. On the other hand, astronauts may need to access tools quickly, so opening and closing the zipper of the pocket takes up too much of their time. That’s why spacesuits also have hook-and-loop closures on the pants legs. Mobility comes first. The suits are made from a lightweight, breathable and flexible material with rear vents and shoulder gussets, allowing full range of motion. In addition, it is tailored to each astronaut, so that the fit is completely personalized. Many tests ahead. Vast has just signed its first contract with NASA to take its astronauts to the International Space Station in 2027. During all that time, just as the hardware necessary for the mission is thoroughly tested, the relevant tests will be carried out on the spacesuit. Above all, it must be confirmed that the materials are safe, durable and compatible with the space station environment. There is no washing machine in space. Both the Vast suit and the rest of the uniforms used by astronauts on the International Space Station, They must be dirt resistant and quick drying. Thus, crew members can wear the same clothes for several days without problem. Clothes that get dirty faster, such as underwear, are changed more often. They are placed in airtight bags and, when enough accumulates, they are added along with other waste in a cargo vehicle that is sent to Earth, so that all of these waste products are burned as they pass through the atmosphere. Not to be confused with the extravehicular suit. What Vast has just presented is the uniform of its astronauts. This should not be confused with the extravehicular suit, which is used on flights and spacewalks to protect astronauts from radiation, fire, or extreme temperatures. The uniforms They are something much simplerwhich can even be worn on Earth to attend events. Still, these are not random garments. There is also a lot of technology behind it. Vast Seasons. Vast’s goal is to support continued human presence in space in the future, with an eye toward space research, industry and tourism. To this end, this company has several space station projects, both single module and multimodular. They also plan to build a station with artificial gravity in the future, something that has not yet been achieved. But first they must gain experience and hours in space. Therefore, the first step will be to take its astronauts to the International Space Station. Now, thanks to NASAhave their first private mission in these facilities on the horizon. If all goes well, the launch window will open in summer 2027. Images | Vast In Xataka | This woman has been accused for years of committing the only crime that has taken place in space. It was all a lie

It’s called “Acubi”, K-Pop stars wear it and Zara is already taking note

by

The long-awaited return of the third season of Euphoria to HBO screens this April seemed to dictate a clear sentence about the future of fashion and beauty: excess is back, but in a darker and more intentional version. The series has abandoned the ethereal, innocent aesthetic of its beginnings to embrace high-contrast makeup, deep ’90s inspiration, and “fierce, unapologetic glam.” As Donni Davy saysthe main makeup artist of the fiction, this new season is “a campaign against clean-girl makeup.” However, while Hollywood pushes hard towards this drama and visual aggressiveness, there is a much quieter rebellion in the streets and on global social networks. An entire generation has decided to turn its back on the aesthetic chaos of the West to embrace Acubi: the quiet cool South Korean style with muted tones and loose silhouettes that is redefining the youth wardrobe. A trend born on the internet. The Acubi style is not an invention of recent weeks, but its current explosion is undeniable. The term comes from the south korean brand Acubi Cluba pioneer in mixing 2000s minimalism (Y2K), “subversive” basics and cyber fairy grunge. It is an aesthetic that avoids metallic pastel tones and takes refuge in a neutral color palette—white, black and gray—, constantly playing with proportions: tight-fitting tops or those with strategic cuts (cut-outs) combined with very loose cut pants. This fashion is gaining traction on platforms such as TikTok and Pinterest since the summer of 2022, standing out for being a creative and mature mix. The accelerator has been K-Pop. If Acubi has conquered the world, it has been thanks to its most powerful ambassadors. Heewon Yuh, youth fashion strategist at WGSN, clarify in cnn that “K-Pop functioned not so much as the origin, but as an accelerator, transforming a local style approach into a globally recognized look.” Female groups with global impact such as Blackpink, NewJeans and Aespa have taken this aesthetic to the stages and fashion weeks. In fact, Ning Ning and Winter, vocalists of Aespa, they showed off their best performance of the Acubi style, dominated by black and asymmetry, during the promotion of his album Armageddon. The data supports this aesthetic tsunami: the hashtag #Acubi generates about 65,000 daily posts on TikTok and 87,000 on Instagram. In addition, interest in Google Trends in Korean fashion reached its peak in the United Kingdom and the United States in February of this same 2026, coinciding with the appearance of idols at London Fashion Week. It is not a simple algorithmic whim. Jaana Jätyri, founder of the forecasting agency Trendstop, explains to cnn that “in periods of economic and social tension, fashion tends to soften.” The Acubi allows young people to be fashionable “without feeling on display.” Along the same lines, Rose Coffey, analyst at The Future Laboratory, maintains that new generations seek “stability and a sense of control” through modular and adaptable garments. However, this search for stability through neutrality does not convince everyone, and has a deeper and more controversial reading. The general obsession with derived aesthetics such as clean girl proposes a “neutral, apolitical and universalized” image. According to Marta De la Rochaan expert from the European University of Madrid, “we have lost the political and identity message that more striking urban tribes previously had.” This is where the analysis of journalist Noemí López Trujillo in Newtral provides a fundamental critical layer. Based on the test Reaction by Susan Faludi, details that the rise of aesthetics that require women to be discreet and ultra-clean can be read as a conservative and anti-feminist reaction. The goal, as journalist Brenda Otero explains, is that women “do not make mistakes, that they all appear equal, that there is no chaos, that they are static and do not change.” Fortunately, although the Acubi shares that silent color palette, its heritage grunge and its asymmetrical cuts save it from falling into the total and apolitical submission of the clean girlgiving it a subversive edge against the desire for women to go unnoticed. From digital niche to universal basic. Far from being a passing fad, the business model behind Acubi predicts a long life. The trend has already made the leap from screens to cash registers. Retailers of fast-fashion such as Shein and British brands such as Minga London already market these garments. Furthermore, mainstream market giants (high street) like Zara and COS have begun to incorporate similar loose silhouettes in their recent collections. Even haute couture has taken note: Gucci’s Cruise 2025 collection and Fendi’s recent catwalks They have presented minimalist designs relaxed people who drink from this same fountain. This success is also a victory for Soft Power South Korean. Professor Dal Yong Jin, from Simon Fraser University, explains in cnn that the growing visibility of Seoul aesthetics is a reflection of the expansion of the Hallyu (the Korean wave). Consuming Korean fashion has become deeply attractive to the international public, strengthening the economy and institutional image of the Asian country globally. The key lies in its extreme practicality. As illustrated in The Straits Times When analyzing urban youth in Singapore, this aesthetic triumphs in all types of contexts – even in hot and humid climates – thanks to the fact that it allows you to show off a well-groomed appearance effortlessly. It is a style that is built on interchangeable and breathable layers: a basic tank top, loose cargo pants and the finishing touch of some metallic accessories or sunglasses are enough to complete the look. Furthermore, although it was initially promoted by women, Acubi has broken gender barriers. Men’s fashion has embraced this trend under an influence Techwear. The “tiny top and big pants” formula translates to men wearing tight shirts or ripped sweaters paired with extra-wide parachute cargo pants, a line that retailers like Lewkin already carry under the “Acubi Men” label. The silent noise of a generation The current fashion landscape draws an interesting dichotomy. While giant Western productions try to impose dramatic or high-contrast aesthetics, global youth has chosen to … Read more

If the question is why men don’t wear skirts, the answer lies in the 18th century: the Great Male Renunciation

by

We have it so internalized, so assimilated, that perhaps you have never thought about it, but here goes one of those questions that sound like a truism: Why do men and women dress differently? Why is it that when we go to a wedding, a gala or an elegant dinner, it is taken for granted that they will wear a more or less sober suit and discreet colors while they will wear dresses and heels? Why are ‘men’s’ clothes usually more functional than women’s clothes? And already, why don’t we wear skirts, like was wondering recently David Uclés? As is usually the case when we talk about fashion (social trends in general), none of the above is the result of chance or simple whim. Why do you dress the way you dress? Things as they are: if you are a man (at least in the Spain of 2026) and you go to a meeting in a dress and heels, it is quite likely that your colleagues will be surprised to see you cross the door. However, the same clothing on a woman would be considered very normal. Because? That same question was recently asked by the writer David Uclés. And it’s not the first. Before him, others had already slipped it, such as the designer and photographer Ana Locking, who in another recent interview on the SER network encouraged men to be much more risky when selecting their wardrobe. “If you want to feel sexy today, dress sexy. The boys’ legs are super sexy, the boys’ necklines are super sexy. Open your neckline, wear a skirt, some shorts, some ankle boots with a little heel,” encouraged Locking after lamenting that, as they mature, men “clip their wings” when they confront the closet. “What they will say comes into play a little bit, feeling vulnerable.” Is it just social pressure? It depends how you look at it. Fashion in itself is a social construct, but the tendency that leads us men to opt for sober clothing and banish skirts, heels and clothing that may be considered ‘extravagant’ from our wardrobes is explained by another reason: the story. In fact, it is not a guideline that has always been applied. Come take a walk through the Costume Museum or El Prado to prove that when it comes to men’s fashion, sobriety has not always been synonymous with good style or elegance. For example, this canvas of King Philip V with his family painted in 1743 by Louis Michel van Loo or this other work from the end of the 17th century, also preserved in El Prado, and in which Jacob-Ferdinand Voet shows us Luis Francisco de la Cerda, IX Duke of Medinaceli. Is there anything that catches your attention about them? Wigs, high heels and brilli brilli? Exact. If you look at both works you will see that the men wear wigs, heels, stockings, loose jackets that fall almost like skirts, and an abundance of bright colors, the kind of clothing that at that time (late 17th century, first half of the 18th century) denoted status. If you think about it it makes sense. What they show us Jacob-Ferdinand Voet and Louis Michel van Loo They are characters dressed in colorful outfits, although they are not what we would say ‘functional’. But… Why should they be? If anyone could afford that kind of clothing it was aristocrats who didn’t have to work. Who doesn’t like heels? William Kremer explained it well in 2013 on the BBC when reviewing The history of high heels and why men stopped wearing them. Again, it may sound like a far-fetched question, but it actually makes a lot of sense and reveals even more about our history. For centuries heels were worn in the Middle East as part of horse riding clothing. And not only for aesthetic reasons. With them Persian soldiers could stand on the styles, stabilize themselves and adopt a good posture to use the bow. When at the end of the 16th century sha Abbas I of Persia He sent a diplomatic mission to Europe to gather support. The nobles noticed the Persian-style shoe. They liked it so much that over time they began to wear high heels that highlighted their size… and their social rank. And all that with heels? That’s how it is. “One of the best ways to convey status is through the impractical,” commented in 2013 Elizabeth Semmelhack, of the Bata Footwear MuseumToronto. Perhaps heels were not very advisable for walking through the countryside and the paved and potholed streets of the 17th century cities, but did the same nobles who posed for chamber painters dressed in clothes as luxurious as they were cumbersome have to do so? “They don’t work in the fields nor do they have to walk a lot.” Why did they stop being used? Times have changed. And the way of thinking. When they review the history of fashion (especially men’s fashion) historians usually stop at the Enlightenment, between the mid-17th century and the beginning of the 19th century, a time in which intellectuals opted for a way of thinking in which what was rational and useful was prioritized. Also education about privileges. Status is no longer an inherited gift, but the result of training and work. As far as fashion is concerned, this translated into a new sensitivity that favored the use of garments comfortable and functional. In England, for example, even landowners ended up embracing a more practical style, better suited to managing their properties. At least that’s how it was among men. The rational aspect stood out among them; The emotional nature was highlighted in them. Did only the Enlightenment influence? No. The Enlightenment mentality played a crucial role, but historians usually point out an episode that (although inspired by the Enlightenment) is much more specific, both geographically and temporally: the french revolution. Against this backdrop, the way one dressed became more than a simple aesthetic choice or a mark of status. … Read more

Artemis II is a million-dollar mission, but its astronauts have had to wear t-shirts as blinds

by

Luckily, all the systems vital for the proper functioning of Orion they are going swimmingly on his trip to the Moon. However, he is having some more mundane unforeseen events, such as problems with outlook wave freezing of the urine reservoir. Added to all this is having to use t-shirts as blinds. And it was not an outburst from the astronauts, but rather direct instructions from Houston. Colder than at Pingu’s communion. The Orion capsule is not exactly the most air-conditioned place. It is very cold inside, so the Mission Control Team, from Earth, has been working to warm it up. Together with the crew, it was decided to move the ship so that it was as exposed to the Sun as possible. But there is a problem with that. The blinds that astronauts use to be able to sleep without the room becoming too bright absorb that heat and overheat. Possible damage to windows. If the blinds overheat, they could transmit that heat to the windows themselves, which would be at risk of damage. For this reason, the Control Team recommended to the crew on April 4 that they remove all the blinds. They explained to them that they understood that this would be very uncomfortable, since the interior of the capsule would be very illuminated. For this reason, they added a most strange recommendation: that they cover the windows with T-shirts. In the communication system recording, a crew member is heard complying with the order and indicating that they would follow the advice. But what advice. delicate windows. We might ask ourselves why it is necessary to protect the windows from the Sun if the ship is prepared to withstand the very high temperatures of re-entry into the atmosphere. It’s a good question, but the truth is that it is not the same type of heat. To begin with, reentry involves very great heat that spreads throughout the ship in a very short time. On the other hand, what comes from the windows is a much more focused and maintained heat. Orion’s heat shield protects it from the heat of reentry. Furthermore, the windows They have an outer layer of fused silica capable of withstanding 2,760ºC. But the inner layers are not as strong. Therefore, if they are exposed to solar radiation maintained and focused directly on them after being absorbed by the blinds, they may not withstand the heat. The future. Despite that small mishap, everything is going smoothly. In fact, Orion already has broken the record of going further than any other manned spacecraft and is close to beating another, reaching the highest speed at which any human being has traveled. If all goes well, this will happen next Friday, April 10, although in Spanish time it will already be the early morning of the 11th. In addition, they stand out for being the first lunar mission in which a woman, a black person and someone who is not American travel. It is not understood how in such an ambitious and expensive mission it has been necessary to use t-shirts as blinds, but at least it has been a failure that does not put the crew at risk.

Gray hair is not wear and tear, it is a cleansing of our tumor cells.

by

For centuries, gray hair has been the universal symbol of aging, a simple aesthetic issue that reveals the passage of time or the excess of stress that sometimes occurs. it’s about covering with dyes. However, having gray hair can be good news for many people, since a study published in Nature Cell Biology just turned this idea on its head: white hair could actually be a biological defense mechanism. The fact that we begin to grow gray hair is for many people a great condemnation that reminds us that age forgives no one, and we even see young people with a lot of gray hair at an early age. But having gray hair can be a sign that is related to the risk of suffering from melanoma, which is one of the most aggressive skin cancers, especially when it is not caught in time. The dilemma of the cell. To understand why having a large amount of gray hair is good news, we have to go to the root of the hair. Here you will find the bulb of the hair folliclewhich is where the hair will grow. One of its fundamental components is the melanocyte stem cell, which is responsible for the pigment that gives color to the hair. That is why when these cells are affected is when you begin to have a color deficit. In this way, research indicates that when these cells suffer damage to their DNA, such as from exposure to the sun or according to agethe body activates a “checkpoint.” The mechanisms of action. When a cell with broken DNA appears on the scene, there is a chance that it will cause cancer if it begins to divide uncontrollably. In order to avoid this, stem cells use a process called “senodifferentiation” that causes the cell to stop dividing and be removed from the tissue. When these stem cells are eliminated, we are left without pigment reserves and the hair is born white, but the body has made sure to eliminate a potentially dangerous cell that could have generated a tumor if this defense system did not exist. The system may crash. Although our body has many defense systems to stop the proliferation of tumor cells, sometimes they fail and cancer is generated. Specifically, the study points to different carcinogens (including chemicals or UV radiation) that can ‘hack’ this cellular decision. Unlike pure radiation damage (which causes gray hair), carcinogens activate specific metabolic pathways (such as arachidonic acid metabolism) that force stem cells to survive and reproduce despite having damaged DNA. In this way, the stress of these carcinogens stimulates the stem cell niche to secrete a molecule called ligand KIT. This signal has the ability to block the “senodifferentiation” that we mentioned before, preventing damaged cells from being eliminated. The ‘good’ news is that the gray hair does not appear, but the bad news is that the damaged cells accumulate and expand, greatly increasing the risk of melanoma. There is, therefore, an antagonistic relationship: The fate of stem cells determines whether we will have gray hair or cancer. If the system works well, the cell is sacrificed and a gray hair emerges. If the system is circumvented by a carcinogen, the cell persists and the gray hair does not appear, but there is a greater risk of a tumor appearing. Aesthetic medicine. One of your goals right now may be avoid gray hair without the need for artificial dyes with the reactivation of these stem cells that have been ‘arrested’ and do not offer their pigment. But for these researchers we are facing a very bad idea. And they specifically point out that the repigmentation of gray hair in certain areas of the scalp could be, paradoxically, an early warning sign of melanoma, indicating that cells that should have ‘retired’ are returning to activity in an uncontrolled manner. In short, the next time you see a gray hair in front of the mirror, don’t just see it as a sign of old age. See it as a small victory for your body: a stem cell that decided to “retire” in time to protect you.

The clothes you no longer wear have a price. For Vinted that price is 8,000 million euros

by

At the beginning of the year We marveled at Vinted’s trajectory. They closed 2024 with more than 800 million euros in revenue and a valuation of 5,000 million euros. 2025 looks even better and they are also planning a share sale that will skyrocket its valuation even more. What is happening. They tell it in Financial Times. The Lithuanian second-hand sales company is exploring a share sale that will increase its valuation up to 8,000 million euros. It is a ‘cash out’ operation, very common in cases like Vinted in which a company has grown a lot in a short time. The objective is for investors to sell their part and recover their initial investment. At the moment the operation is not closed, although there is talk that it could be completed at the beginning of 2026. Why it is important. The second-hand items market has been transformed with the appearance of platforms such as Wallapop, Milanuncios or Percentil. However, none can boast Vinted’s figures. The company has managed to stand out with a clear strategy focused on clothing and the promotion of its own payment system, Vinted Pay. Benefits. Vinted reached 813 million euros of revenue in 2024. According to Thomas Plantega, CEO of the company, they expect to close 2025 with record revenues that will exceed 1,000 million. The gross sales value of items on the platform could exceed 10 billion euros. As for net profits, they have not given forecasts, but in 2024 they have already tripled compared to the previous year, reaching almost 77 million euros. Diversification. Vinted was born with a clear focus on the buying and selling of second-hand clothing, that is where it made a name for itself and managed to differentiate itself from other more general second-hand platforms such as Wallapop. Recently the company has begun to open its categories and today we can now find electronic devices, video games and home furnishings, among others. The plan is to continue expanding. Target: USA. Vinted already operates in a total of fifteen countries, although not all of them are connected. Specifically, the United Kingdom is not connected to the rest of Europe, so they can only buy and sell within their borders. The next step will be to jump into the US market and the idea is to connect it precisely with the United Kingdom. Speaking to Bloomberg TVthe company’s CEO assured that the second-hand market is very underdeveloped in the United States, which represents a great opportunity for Vinted.

The connected glasses look like a lot of fun. Until they force you to wear them at work

amazon he doesn’t trust his workers. It has never done so, and this is demonstrated by the measures that have been filtered and that served the same purpose: to monitor them and prevent productivity from dropping. Some control is reasonable, without a doubt, but this company stopped being that a long time ago and became in a nonsense. We are talking about a company that patented a wristband to find out if employees relax and they start to work a little less. Which was discovered to have automated tracking systems to evaluate productivity rates of each worker. Which used AI cameras to monitor delivery vans and drivers during 100% of the journey. that ended receiving fines due to this strenuous monitoring and had to change the algorithm that penalized productivity data for going to the bathroom. A company in which some employees they had to urinate in bottles to avoid wasting time and others said that working at Amazon was like being in a prison. Augmented reality glasses to work better… Well, now Amazon is working on augmented reality glasses that will follow the line of the Meta Ray-Ban Display. They are likely working on a version for end users, but what the company has officially confirmed is that I was developing some glasses for your messengers. After delivery, the courier will take a photo by pressing a button… which apparently is not on the glasses themselves. With them, they indicate in the press release, couriers will be able to “identify dangers, reach the customer’s door without problems and improve deliveries.” The glasses make use of AI, artificial vision, cameras and sensors to offer all their options to couriers. Thus, when a courier arrives at a delivery location, the glasses are activated and the courier has information about the package to be delivered on the display (a monochrome HUD with information in green). This same HUD allows you to follow navigation instructions similar to those of GPS navigators – but with a much more schematic design – to find the client’s home. The courier will also take a photo to confirm the delivery and can share it as a demonstration of that delivery if there are problems. …and to monitor workers more than ever The company is testing a prototype with the help of hundreds of couriers in the US, and is collecting information and feedback from those “beta testers” in order to refine the product. On paper, these glasses may seem like a useful aid for drivers, but it is inevitable to think that they also They can be used for much more exhaustive monitoring and control of those drivers and messengers. Thanks to this device, Amazon will, for example, have absolute control over the location of the couriers and their productivity when delivering packages. Are they fast or slow? Do they make mistakes? Here the border between supporting technology and that which allows for labor control is blurred. It is true that it provides advantages in terms of efficiency and even security, but the amount and precision of the data collected by glasses like this raises questions about worker privacy and, once again, the degree to which Amazon can supervise its employees. And like her, of course, many other companies that may also end up making this type of device a mandatory element for employees. In the EU, however, it seems more complicated that this type of wearables can be used: there are legal precedents that years ago already posed a clear obstacle to this type of monitoring, but it remains to be seen if these measures are finally also adopted among EU workers.
