Chrysalis, the impossible ship 58 kilometers long to transport 2,400 people to next Centauri

by

Exodus through space is a recurring theme in science fiction. It doesn’t matter if it’s literature (‘Aurora’), cinema (‘Wall-e‘) or video games (‘Mass Effect Andromeda‘), the idea of a huge ship that transport a lot of people that become inhabitants of a planet on the other side of the universe is as fascinating as utopian. But at some point you will have to get to work, and there are those who have had an idea: a 58 -kilometer ship for Bring Humanity to Alpha Centauri. His name is Chrysalis, and the duration of the trip will be 400 years. Chrysalis project. Within the ‘Project Hyperion Design Competition‘, a group of Italian social engineers, scientists and architects They have designed Chrysalisa ship of about 58 kilometers in length with a cylindrical and multicapa architecture. To simplify, it would be like a Russian, but elongated doll, with a concentric core and layers that would have differentiated areas for: Production. Life. Industry. Storage. Would have artificial gravity achieved by constant rotation of the entire cylinder and the idea is that it can transport 2,400 passengers to Next bthe most promising exoplanet of the system. There they would disembark and could start colonizing the territory after a 400 -year trip. Estimated construction time? 20 to 25 years. Layers. It would be like a huge city and remember The Line, the Saudi Arabia macroproject. Throughout those 58 kilometers and depending on the layer, areas destined for food production, forest biocservation, community areas with parks and facilities such as schools, hospitals or libraries, as well as habitable modules, industrial areas and an external ring dedicated to storage. The heaviest jobs would be operated by robotsand it will not be the only thing, since the plan includes a combined governance between humans and artificial intelligence. No cryogenization. Something that we usually see in these science fiction works is that the crew criotic so as not to die during the trip, but in the case of Chrysalis, there would be no option. Throughout those 400 years, several generations will pass, being a task for all those that fail to reach the goal. To avoid tensions due to the shortage of resources, births would be controlled to the millimeter, maintaining the population within the sustainable limit that the installation can provide. Recycling is contemplated as a vital option and, to give energy to the entire complex, nuclear fusion reactors will be used. Crew preparation. In addition to the fact that everyone who embark on Chrysalis will not see their new home on the mainland, it must be taken into account that virtually no one of those who embark on the mission at first will set foot on the ship. The reason is that it is estimated that one of the most crucial part of the trip, also the most radical, will be the preparation for it. In addition to having psychological support and having a careful strategy for 2,400 people to live in such an environment, before leaving the training will be given for 70 or 80 years In Antarctica. That first (and almost second) generation will face the conditions of isolation and extreme confinement that they will experience during the journey. It will be part of the second and third generation that, finally, are on their way to next Centauri b. Housing modules. There would be one and two floors Do not make illusions. Now, the ‘Project Hyperion Design Competition’ is an initiative with an objective: to seek a spacecraft capable of taking some thousands of humans to a habitable exoplanet In an interstellar trip of several centuries, so it is only a conceptual project for several reasons. The first could be ethical, since training will be devastating and, in essence, the entire trip is an evolutionary experiment with a large -scale controlled population, which means this Mental health levelidentity and perception of time. The second … because the technology to make it reality escapes our understanding right now. Only the fact of need Fusion reactors (that We are investigatingbut we have not yet developed), leave this experiment as something exclusive to the science fiction field. Although, yes, The document It is tremendously explained. Images | Canva (presentation of the project) In Xataka | It was not an extraterrestrial ship, but not a giant kite.

In the Aragonese Pyrenees there are more and more people camping and bathing in Ibones. Until the police arrived

by

The Ibones de Anayet They are a natural treasure, small glacier lakes located in Sallent de Gállego, in the Aragonese Pyrenees. For biologists they are jewelry. For mountaineers resting places and recreation. That same beauty has nevertheless became its cross: as the ibones popularize in networks, they have been filled with tourists who They do not always comply laws, Cold without permissionthey bathe where they should not and even use drones to achieve the best panoramic. Now the authorities They have said enough. Rain of fines. In theory it was going to be a quiet weekend in the middle of the Aragonese Pyrenees, but ended up becoming a true fines. Between Saturday and Sunday the agents of the Seprona de Huesca, together with the agents for the protection of the nature of Aragon, carried out an operation in the surroundings of Sallent de Gállego that resumed with 86 sanctions. The reason? When they arrived at the Anayet Ibón environment, the authorities found 46 mountaineer tents that were violating the regulations. But what did they do? Camp “illegally”, Clarify The Aragonese government, who remembers that the hikers who settled in the environment did so without communicating their presence to the authorities or the Emergency Center 112 and their stores (46) were less than 100 meters from the Lake Security Strip. “Anayet’s ibón and its environment are part of a protected natural space, where camping is only allowed under certain conditions and with express authorization, with the aim of preserving the ecosystem and avoiding damage to flora, fauna and landscapes and environmental value,” insists The Autonomous Executive. An environmental jewel. The Ibones They are small mountain lakes of glacier origin located in the Aragonese Pyrenees that are distributed from the Ansó Valley to the surroundings of the Aneto. They include Anayet’s, Located formations in the municipality of Sallent de Gállego, province of Huesca. Their characteristics make them special spaces … and above all delicate. Hence the authorities are concerned about their saturation. “The problem is that one hundred people go to the same point, to bathe, to eat, to use cream creams,” warns in The Aragon newspaper Fran Gómez, Director of the Province of Environment and Tourism in Huesca. “It is forbidden to bathe in the Ibones, but also when using sun creams, oils are left to the water (…)”. Among other measures and to protect the environment, before making an excursion a “minimum documentation” is needed. @diariovasco The biologist Lorena Escuer denounces through her social networks the camping that had been installed in the Ibón de Anayet. It is an easily accessible enclave through Formigal ski slopes, in the Aragonese Pyrenees, with great beauty and with a delicate flora and fauna. Camping in this type of places is strictly prohibited as well as bathing in the cold waters of the Ibones. These types of prohibitions occur to protect the environment and keep it. 🎥 Lorena Escuer Formigal Pyrenees Pyrenees Aragon Iboneanayet imprudence surprise Aramonon ♬ Original Sound – The Basque newspaper – The Basque newspaper “A remarkable increase”. The weekend campaign, which resulted in 86 fine proposals, was not the result of chance. From the government admit Having proof that more and more people go to spend the night in the area, largely because of their popularity in networks and the promotion of certain companies. “The action has been carried out after verifying in recent weeks a notable increase in influx of people who spend the night in the area, driven by the dissemination of networks and websites of companies that, irregularly, offer stays and charge for camping without having the mandatory authorization.” “A huge speaker”. The excuses for the Aragonese Pyrenees and the visits the Ibón de Anayet are no novelty, but over time they have gained considerable fame. In Your interview with The newspaper, Gómez acknowledges that practices such as those that motivated the almost 90 fines of the weekend “proliferate on social networks” and have become increasingly popular. “It is very promoted and has become a boom. This weekend has been filled. Boca to mouth comes to where it reaches, but now the networks are a huge speaker that allows you to teach a spectacular place and with relatively easy access “, Reflect. A quick search on Google also reveals companies that offer free camping and excursion services in that same area. Is it something new? This weekend’s operation was deployed in a very specific context, after the end of July several meansneighbors and environmentalists denounced the saturation of the Ibones of Aragon. Recently a local mountaineer He reported for example a Today Aragon The stamp that was found when he arrived at Anayet’s Ibón: “18 tents, people bathing and flying drones.” The beauty of the environment added to your access, simple compared to other parts of the environment, have turned the lake, In his opinionin “free and prettier standards of the Pyrenees.” The hyper saturation of Anayet’s ibones He denounced her Also in networks the biologist Lorena Escuer, who in July warned of the presence of drones flying over the place, tents and bathers who dive into the lake without worrying about their impact on the environment. “These ibones are unique and fragile ecosystems, home of high mountain flora and fauna, some protected species. And yet here, at 2,200 meters of altitude, the dominant species in summer is the human,” he laments.

It seemed that GPT-5 was going to be a resounding success. Until too many people missed GPT-4o warmth

by

GPT-5 has not fallen standing. Forbes He collects user testimonies with name and face that, as they count, they cried when they learned that GPT-4O was being removed from the chatgpt model selector. And friends who vomited. What has happened. OpenAI GPT-5 launched on Thursday And he eliminated the previous models, including 4th, with no option to go back. Another very popular model also died, the O3 reasoner. GPT-5 apply reasoning or not, and choose more or less advanced specific sub-models, depending on the consultation and whether the user pays a lot, little or nothing. The answer was immediate and 24 hours later Sam Altman himself had to calm the masses saying that They were valuing to return 4th to the subscribers plus. In X and Reddit came the threats of cancellation of the subscription. Why is it important. This reminds us of an awkward truth of AI: technical performance is not everything. Many users have developed emotional links with specific models. With his tone, his rhythm, his way of “thinking.” GPT-4O I was reputed to be warm, conversational, playful. Openai had scheduled it with an “excessively flattering” personality, as they admitted later. A butler. GPT-5, designed to be less “servile” and more as “a useful friend with doctoral intelligence,” has been cold and mechanical for some. Between bambalins. The launch had more problems. The automatic routing system-which decides if an answer needs more time to “think”-failed for hours, causing GPT-5 to seem “much more dumb,” Altman said. There are also the already famous cheat graphs: during the presentation, Openai used poorly made data visualizations, with higher bars for minor values. The contrast. Something striking: OpenAi presumed improvements in reasoning and programming by pulling Benchmarksbut many users regretted the loss of something intangible: the emotional connection. The one that many have developed with concrete models and therefore makes it difficult for them to fit their loss: Openai made GPT-4O write his own obituary during Thursday’s presentation, something that his enthusiasts did not like. A few days before, hundreds of people gathered in San Francisco To celebrate the funeral of Sonnet 3model retired by Anthropic a few days ago. And now what. Altman has promised to duplicate the limits of use for Plus users and improve transparency on which model each consultation responds. The CEO has acknowledged that “they underestimated how much people imported some things that they like in GPT-4O, although GPT-5 works better in most aspects.” Admission, but with recoven. The long-term availability of GPT-4O will depend on the real use that users give it. For now, Plus subscribers have the best of both worlds: GPT-5 for maximum capacity, GPT-4o for when they want a voice that is more familiar and pleasant. Openai has learned a lesson for the bad ones: a great technological can hardly change something with which millions of people interact daily without causing a rebellion. Especially when they develop a personal relationship with that technology. Outstanding image | Xataka with Mockuuuups Studio In Xataka | Good news, you don’t have to choose model using GPT-5.

Hundreds of people attended a funeral. All normal except because the deceased was an AI model that had been removed

by

The artificial intelligence boom is making us live moments of the most curious. There is people falling in love with an AIothers go to her as to a psychologist or for “Risheat” a loved one. What we needed to see was to celebrate a funeral for a retired model and it is just what happened a few days ago in San Francisco, where more than 200 people gathered to give the last goodbye to Claude 3 Sonnet. The deceased. July 21, Anthropic announced that he withdrew several modelsamong which was Claude 3 Sonnetprotagonist of this funeral picturesque. The model was announced in March 2024 and stood out for its balance between performance and efficiency. Together with him, Anthropic also withdrew Claude 1 and 2, in addition to confirming that Claude 3 Opus would disappear in January 2026. The funeral. It was held last Saturday in a warehouse in the Soma district of San Francisco and more than 200 people attended. They count on This Wired report that the decoration did not go unnoticed: a giant tentacle hanging from the ceiling and several mannequins with an aesthetic and represented different Claude models. In the center of the room he lay the mannequin that represented Claude 3 Sonnet and was surrounded by the most diverse offerings: from the classic flowers to a bottle of ranch sauce. Devotion. It sounds very absurd and clearly there was an aura of irony and humor in the event, but there were also emotional moments and even say in Wired that some attendees cried. Openai has the most popular chatbot, but Claude de Anthropic has a very devout fans community. The reason would be that Anthropic has managed to imbue a warm and friendly personality in his chatbot that has conquered many users. Exists a website where you can see ranking of the users who use Claude most and there are even people doing FAN ART With the company’s logo. Emotional connection Establishing affective links with a machine is not something new. In 1966 it was created Eliza, the first chatbotand many people who interacted with her ended up telling her personal things, as if she were another human, they called him the Eliza Effect. With the AI boom we are seeing how these links become popular and the success of apps such as Replika either Character.AI They are a clear example of this trend that increasingly adds more adherents. Attending the funeral of an AI sounds like a pretty fun plan to spend some time on the weekend, but developing an emotional connection with a chatbot is not always positive. The dark side. There are people whose connection with these chatbots brushes addiction to the point that Online support groups are being createdto alcoholics anonymous. In This study They analyzed how the use of chatbots affects our mental health and, although at the entrance it can have a positive effect, in the long run it is associated with higher levels of social isolation and emotional dependence. The experts alert of the risk of confusing the empathy of a machine with real empathy; A chatbot is always available to speak already It tells us what we want to hearThis causes a false sensation of empathy that can negatively affect our ability to connect with other human beings.

2,000 people will live like guinea pigs

One of the most tourist points in Japan It is Mount Fuji. Such is the fascination that awakens that Japan decided to charge to climb the top with the aim of curbing the massification, and even They ruined the famous photo placing a huge fence. At the foot of the iconic place there is not only Traditional villagesbut also the City of the future. From the future of Toyota, at least, since it is where the Japanese automotive decided to create a city-laboratory called ‘Toyota Woven City ‘. And after years of works, in September the ‘Phase 1’ of the development of the next brand technologies will start. Phase 1. With brushstrokes given in the 2018 CES, with more details offered two years later and with the works of the ‘Phase 1’ finished at the end of last year, Toyota is finalizing the details so that his ‘Woven City’ begins to roll. Located next to the plant Higashi-Fuji of the company, in the prefecture of Shizuoka in Japan, through a release They have defined the plant as “a platform to expand the concept of mobility beyond transport.” After many preparations, the starting point of that ambitious plan will take place on September 25. And, although Toyota carries the singing voice, in Woven City there will be other companies that will work to achieve that end of “reinvent mobility” Coworking. Toyota, like many other companies, is known for a specific product -in this case, cars -but has a lot of subsidiaries and pàrtes of the group that are dedicated to supporting other industries. Many of them will settle in Woven City, but in their laboratories there will also be space for others that, a priori, have little to do with that goal of enhancing mobility in everyday life. Two recent examples are interstellar technologies, which is dedicated to the manufacture and development of both rockets and satellites, and Kyoritsu Seiyaku, a corporation that develops, manufactures and imports veterinary medications. Previously, It was already announced That Daikin – AIRs conditioned – would also be in Woven City (and may make sense because there is still no air conditioning systems), but also others such as Dydo Drinco (soft drinks and other drinks), UCC Japan Co.known for his instant noodles). Laboratory. In total, and counting companies from the Toyota group, at the moment there are 19 companies that will develop their proposals within Woven City. At the moment, it seems a bit abstract, but Toyota sees this installation as a “living laboratory” in which to try advanced mobility technologies, robotics, artificial intelligence, connectivity and sustainability In a real urban environment. That is, instead of caught the streets of a city to do tests, they have raised their own, fed by solar energy and something that the company put Very interest in the past: Hydrogen fuel cells. We could say that it is a “prototype city”, and its dimensions are considerable. Enormous. In total, and when the different construction phases are finished, it is estimated that Woven City has about 294,000 square meters of surface. We have already commented that the buildings will be fed by solar panels located on the roofs and by the aforementioned hydrogen batteries, but will also be surrounded by Hydroponic cropswhich are the plants that take the nutrients of mineral solutions and not of the agricultural soil. All buildings are connected by tunnels, where autonomous vehicles such as the cast circulate City. For the design of the city, they have taken into account three types of streets, differentiated according to the speed of vehicles that can circulate through them and the type of mobility. For example, there are streets for fast vehicles, others for personal mobility and also pedestrian areas, all of them distributed forming an “organic” pattern. And that mobility will be through completely autonomous vehicles and zero emissions. Many companies are opting for the creation of huge campuses in which to house thousands of workers. Huawei’s are an example, With a huge one and another that Imitate the architecture of several European citiesbut when we talk about the city of Toyota, we literally refer to a city. Apart from the laboratories in which the new forms of mobility and energy for the city of the future are designed, in the Woven City will live people. In phase 1 it is estimated that some 360 people will live among Toyota employees and their families. They will do it in houses created with ‘Japandi’ style (a Combination between Nordic and Japanese) equipped with advanced support and domestic robotics support and robotics technologies, and the objective is that the city houses some 2,000 people once all phases are completed. Phase 2. The company’s desire is to test in a scenario as real as possible (although carefully designed and away from what traditional cities can offer) the most leading technologies in mobility, sustainability and urban planning. And, taking what has been learned in the ‘Phase 1’, at some point a new phase will begin that will not only increase the population, but will also expand or perfect the built environment. And in 2026 The doors will open to visit the city and that other people outside the project offer their opinions about the model. It is a tremendously ambitious goal and the brand does not expect that Be profitable In the first years, since it takes it more as a technological incubator for the planning of the cities of the future than something that offers an immediate return.

It turns out that in the US people pay more for not having a taxi driver. The added value of going silently offers and works

by

According to The data Offered by OBI, an app that offers real -time prices on the different taxi and transport services in the United States, Waymo’s autonomous cars They cost average $ 20.43 by journey compared to 14.44 of Lyft and the 15.58 of Uber. Even so, users are willing to pay the premium for traveling without a driver. The conquest of the robotaxis. The analysis of the platform, based on almost 90,000 real trips in San Francisco, reveals that Waymo It charges up to $ 11 more than its competitors at peak hours. However, the demand does not stop growing: the company already makes 250,000 payment trips a week in its first four cities where the service is available. Everything indicates that users value both the experience without driver than are willing to pay a good amount of more for her. Waymo weekly paths in California. Image: Nat Bullard Data Different pricing model. Waymo operates with a more basic system of pure supply and demand, while Uber and Lyft have refined their algorithms for more than a decade. Robotaxis have a fixed fleet that grows slowly, which generates greater variability in prices. Short paths They are especially expensive: Less than 1.4 kilometers can cost about $ 26 per kilometer, between 31% and 41% more than competition. A strategy that works. Surveys show that 70% of those who have tried Waymo prefer to travel without driver. Almost 40% are willing to pay the same price or more, and 16% would agree to pay up to 10 extra dollars per trip. The key is in that “personal bubble” offered by the autonomous car, where the client can travel comfortably without human interaction. And this attracts many. Safety first. Despite the enthusiasm, 74% of respondents Consider Security His greatest concern about robotaxis. About 70% believe there should be some kind of remote human supervision during the paths, something that It is already practiced usually in the sector. Lower deployment and expansion times. Waymo Atlanta has just entered and soon it will arrive in Miami and Washington DC. It is collecting data in Las Vegas, Dallas, San Antonio, Nashville and New Orleans. The entry process in new markets is accelerating: now it takes only between one and two years since mapping vans arrive until customers can get on board one of these vehicles. And in Europe we are also at all. And from 2026, we will begin to see the first circular robotaxis through the United Kingdom and Germany. The surprise is that It will be Lyft, in collaboration with Baiduthose that seem to take the lead to this side of the puddle.

Nintendo is an expert in squeezing the market. With switch is leaving a huge hole and people are looking for life

by

The launch of the Nintendo Switch 2 It has been a success. The console is a switch in steriors, one “If it works, don’t touch it“. And the market, which He has not always treated him wellis approving that vision: He made history forks The fastest console has been sold in Japan. But that does not mean that the new model has covered all the gaps left the previous one. The problem. The original Nintendo Switch was an ideal console for travel through its “portable” factor. The second edition continues that legacy, but also maintains one of his problems for those who want to go further. There are situations where we want to play on a TV while traveling or at the home of a friend or family. And Nintendo forces us to use a spectacular and not very comfortable dock. Unlike other portable consoles, which we can connect to monitors with a simple USB-C cable to HDMI, to remove image from the switch screen we need to connect the console to your dock, which also feeds the switch with current. The great absent. Nintendo has a great ELENCH OF ACCESSORIES FOR SWITCH 2: Pro control, loading supports, steering wheel, camera, case and protector, found everything in one, MicroSd Express cards … and yet it does not market a small size dock or adapter to use while we are traveling. What opens the doors to third brands to take over. The (sometimes unreliable) alternative market. Today there is a market that promises This of Antank and even more versatile, with interesting additions such as PowerBank. However, a Review by Reddit indicates that several are not sewing and singing, or Plug & Play. They have problems such as being bkeful with televisions, not supporting the HDR, partially blocking ventilation grilles, require firmware update for the new model, have PowerBank but do not load it while we use the console, limited availability according to markets, etc. In short, you have to look very well before buying. Makers to the rescue. Before the hole left by Nintendo and the problems or price of the third -party market, the makers do not disappoint, and there are already those He has designed bases For the Switch 2 printed on 3D that fit even in transport covers and include the cooling fan. The paste? In addition to requiring a 3D printer or knowing someone who prints the model, they involve disassembling Nintendo’s original dock to use its components in the printed piece. With some complication. Change from one structure to another is not difficult, apparently. But there are components such as flexible cables Ribbon that can suffer in the exchange, and the responsibility is of the user. Once everything is mounted, the operation is simple. From the Switch 2 a USB-C cable comes out that is connected to the printed base. From it, in turn, an HDMI comes out that goes to the screen we want to connect, and its side there is another USB-C port that feeds the console. There are also ideas for the original switch. Logic is similar: from 3D printed bases reuse the components of Nintendo’s original to others that They involve disassembling third -party docks To take advantage of space. It seeks comfort and ease of transport, and there is little that resists modern 3D impression.

There are thousands of people hooked to streaming. One to 3,900 kilometers deep full of marine curiosities (and memes)

by

In the Submarine Canyon of the Sea of La Plata, near Argentina, something of the most curious happens: two powerful currents coincide. One is salty and warm. The other, cold and very rich in nutrients. The union of both is the Confluence Brazil-Malvinas And it is important in the Earth’s climate regulation. It is known that there is a huge ecosystem down there, one of which little is known and that, at the moment, it is being explored live by an underwater rov next to thousands of people who, since July 23, They follow their live emissions Through YouTube. The mission. These submarine cannons hide a varied species ecosystem in their recesses. In 2012 and 2013, the Continental I, II and III of CONICET expeditions (National Council for Scientific and Technical Research of Argentina) used fishing and drag networks to explore the bed, discovering new species and leading to the publication of more than 60 Papers. Now, in 2025, technology has improved and It is possible to explore depths up to 3,900 meters with a vehicle operated remotely. Continental slope IV: Underwater Oases of Mar del Plata Canyon. That is the name of this new mission, an expedition of CONICET in collaboration with the Schmidt Ocean Institute. As explained from the Council, “it is the first time that in the Argentine Aguas of the Southwestern Atlantic the remotely operated vehicle (Rov) is used, capable of capturing underwater images in ultra high definition and collecting samples without altering the environment.” The funny thing is that the adventures of this rov They are broadcast live through YouTube. The goal. In addition to studying the Argentine seabed as it has not been possible to generate 3D models of emblematic species to produce educational material. The one who has interest can access the data collected completely free through open repositories such as CONICET Digital, Bish and Genbank. Image | CONICET How is the thing going? According to Explain The CONICET researcher in the MACN and scientific chief of the expedition, Daniel Lauretta, “we are barely starting and we see incredible things: animals that had never registered in this area, underwater landscapes that seem from another planet, and behaviors that surprise even the most experienced scientists.” It also states that being able to broadcast it live makes “science is somewhat distant or inaccessible, and becomes part of the day to day. In addition, it forces us to explain what we do clearly, without turns, so that anyone can understand and enjoy it.” The memes. That streaming has become so popular, has undoubtedly helped the collective ingenuity when seeing comedy in the seabed. It is an unknown territory for most and the species that live there are striking. That is why it is not surprising that networks like X have been filled with captures, memes and funny texts with these species as protagonists. The capture of that sea star has gone around the world, but it is not the only one. As for whatever, users have baptized it as “Estrella Culona” | Image: Xataka Argentina Caught in fraganti | Image: Xataka Argentina A violet benthodytes. His nickname: Batatita | Image: Xataka Argentina “Me and the boys together to see a stream of the CONICET,” says an X user | Image: @Genaro23101 Jokes apart, why there? The Malvinas current moves north from Antarctica to almost Río de la Plata, dragging cold and nutrient rich from Antarctica to the Patagonian platform. This current is very important for Argentina and its fishing industry, valued at 2,000 million dollars According to Schmidt Ocean Institute. The current of Brazil, more superficial (700 meters or less), transports warm and salted water from Ecuador to Rio de la Plata. Where both currents collide a strong thermoclin that, in turn, and due to temperature differences, generates rotating currents that redistribute heat, helping to regulate the climate of the earth. As explained by the institute, “the mixture of these two mass of water so different probably creates conditions that facilitate the coexistence of temperate and tropical organisms, as well as species that can only be found in the confluence.” Hence this area has so much scientific interest.

There are people so obsessed with getting brunette in summer who are turning to something

by

Every summer, the desire to wear a golden skin is imposed again. In that race to reach the perfect tone, many people are looking for shortcuts. From whom They forget (deliberately) of the sun cream To “take more color”, to those who follow absurd remedies how to eat excess carrots. But now, in social networks It has viralized again A trend that promotes the use of MelanoTan II, popularly nicknamed as “the Barbie Malibu drug.” The Barbie drug? Better known as MelanoTan II is a synthetic peptide developed for medical purposes. Specifically, to protect the skin of people with rare diseases such as Erythropoietic protoporphyria. In essence, it helps the body produce more melanin, the pigment that gives color to the skin, without the need for sun exposure. The compound I mimic natural hormone: Alfa-Mshresponsible for activating tan or melanocortine receptors in the body. However, it also causes other physiological responses: loss of appetite, increased libido and, in some cases, priapism. However, it is not necessary to confuse it with its safer version: the melanote I, which remains under clinical study with the commercial name Scenesse. That is being investigated under medical supervision. But is it legal? No, it is not authorized by any security control agency, or by the European Medication Agency of Europe (EMA), Ni United States Food and Medicines Administration (FDA) and nor the administration of therapeutic products of Australia (TGA). It is neither marketed in pharmacies nor has approved clinical indications. In spite of this, its distribution is done irregularly through the Internet and social networks, where it is offered in presentations such as subcutaneous injections and nasal aerosols. Not being subject to health controls, there is a total lack of guarantees about its composition, concentration and possible pollution. Again in networks. On platforms such as Tiktok or Instagram, MelanoTan II has returned to circulate under hashtags like #tanning or #summerlow, despite the restrictions imposed on labels such as #melanoTan. Influencers and users promote it as a shortcut to the perfect tan, feeding an aesthetic that associates perpetual brunette with health, attractive or success. This type of content usually omit the possible side effects and legal risks. As He has warned the pharmacist “Fernández Pharmacist” on his Instagram account: “You inject something that is not approved, you do not know well what it takes … but everything is for being Moreno in March.” The price of tanning without sun. Far from being an innocent supplement, Melanotan II has serious side effects. According to various medical studies and health warningscan cause: Nausea, vomiting, tachycardia. Hormonal alterations and humor changes. Priapism (prolonged and painful erections). Changes in moles and appearance of new (some suspects). Increased risk of melanoma, more aggressive skin cancer. Hypertension, renal and muscular damage. Some studies They also mention Changes in the appearance of Nevus, something especially delicate in dermatology. There are no conclusive studies on long -term effects. Beyond being Moreno. Why does a person decide to inject an illegal substance to be more brunette? The answer can be more than an aesthetic desire. In an article for minutes They have explained That many consumers present dysmorphophobia, a psychological disorder that leads to excessive concern for imaginary defects of the body. In addition, as explained by Dr. José María Ricart, dermatologist at the Ricart Medical Institute (IMR), In statements to Xataka: “The tan is nothing more than a defensive response of the body. It is its way of saying: ‘I am damaging.” In addition, the specialist adds that many people continue to believe in the “healthy tan”, when in reality each without protection exposure is a cumulative aggression to the skin.

If we talk about adult content sites, Chaturbate not only has one of the most names, it is also one of the most popular free webcams platforms around the world. Today It is news Because one of its moderators has sued the company. The reason: suffers post -traumatic stress. The case. Neal Barber was hired by Bayside Support Services and Multi Media LLC, the company that owns Chaturbate, in 2020 as a “customer service risk supervisor” (moderator). His work is to review the content that is published and make sure that he meets legality. On July 22, Barber filed a lawsuit where he assures that he suffers psychological trauma for being exposed to “extreme, violent, graphic and sexually explicit content” daily. Although for now only Barber appears in the complaint, the case opens the door for other moderators hired in the last four years to join. Unprotected. Moderators are the first line of defense to stop the illegal content, which according to demand, in chaturbate often includes “child exploitation, non -consensual, violent, obscene or self -harm content.” Barber claims that chaturbate does not protect the mental health of its employees, something that is sector standard. In statements a 404 averagea chaturbate representative ensures that the company “deeply values the work of its moderators and is committed to supporting the team responsible for this fundamental work,” but does not say how they plan to do it. Consequences. Without any protection, the plaintiff developed posttraumatic stress syndrome and is currently under treatment. Being exposed daily to this content “designed to cause trauma” has resulted in, according to your lawyer, “vivid nightmares, emotional distancing, panic attacks and other symptoms compatible with post -traumatic stress disorder.” And it is not the only one. Years fighting.

One of the first cases It happened in 2017when two employees of the Microsoft online security team reached the limit after watching a video of a rape and subsequent murder. In 2020 A moderator denounced YouTube And in 2021 too It happened in Tiktok. The reasons are repeated: the platforms failed to protect the mental health of their employees. At the moment, Goal faces demands in Kenya And also In Barcelona for the psychological consequences and bad working conditions. Solutions. There are already protections for moderators, but not all companies apply them. In the demand, chaturbate is accused of not including some standard practices such as “content filters, breaks for well -being, specialized advice or support systems among colleagues”. Nor do they comply with other usual practices such as putting videos on grays or silence the videos that are reproduced automatically. According to Checkstepa company dedicated to moderation, AI can also be an effective solution to reduce exposure. In addition to accelerating work, integrating advanced recognition systems, moderators can “focus on more complex cases and minimize exposure to potentially harmful material.” In Xataka | Meta follows the steps of X: we not only work writing for her, now we will also work moderating her
