We have accepted that sport is “medicine” for the body. Now science is discovering its side effects

by

Physical exercise can be prescribed as a drug in doctors’ offices, even though it is not packaged in a simple pill that we take. This is because the evidence behind it has made it more than clear that playing sports can prevent a large number of chronic diseasesI know even have a very good old age. But behind all this, too There is a negative part behind doing physical exercise. Its side effects. If we accept exercise as a drugwe must also accept that every drug has a leaflet, specific doses and of course some adverse effects. That is why as a society we have the problem of having begun to sell the fact of “exercising” in a generic way, ignoring the fine print that this task has, as recognized by the Spanish Heart Foundation itself. And it has a very simple solution: personalizing physical exercises per patient. The problem of metaphor. The slogan “exercise as medicine” is undoubtedly an excellent marketing campaign within the world of public health, but for science there are several important flaws. As different scientific studies point out, exercise does not act like a classic drugsince it does not have a predictable response in a patient as if it occurs as a pill. This forces us to always think that the effect can be very different for each person. In this way, by calling exercise a drug we can make invisible the diversity of individual responses. And there is no universal “squat pill”, since doing this exercise in a specific person can be very beneficial, but in another it can be be the origin of a pathology due to overload. And all because we throw ourselves into exercise without planning how to do it, since we find it very easy to pick up some weights and start building biceps. The damage numbers. We often hear that it is a great danger to stay sitting on the couch, and it is true because they are many diseases related to a sedentary lifestyle. But according to different studies done in the United States, people who meet or exceed the recommendations for moderate or vigorous exercise They have a 44 to 66% chance of developing musculoskeletal injuries. than subjects who remain inactive. In addition to this, although cardiovascular health improves with physical exercise because the heart reduces its heart rate, for example, the “maintenance cost” of the physical body increases dramatically with the amount of exercise done. A question of biases. Without a doubt, this is one of the most critical points that scientific literature reveals regarding the lack of transparency in clinical trials related to exercise. This is something that was seen in an analysis that included 103 trials on knee osteoarthritis, where it was found that 6% of the participants suffered direct damage from this exercise. But the most worrying thing is not the number, but the low information: many patients who abandon studies due to pain or discomfort are not classified as “victims of adverse effects”, which generates an artificially high perception of safety. This problem is repeated in oncology, where the motto “exercise is medicine in oncology” live with non-trivial adverse events which have forced us to propose much stricter monitoring systems to protect patients. We pass each other sometimes. The underlying problem in this case is undoubtedly recommending intensive or complex programs without a clear benefit/harm relationship compared to an alternative that is much simpler. But, on the other hand, we also fall into the phenomenon of “quaternary prevention” making medicine focus on avoiding harm from its own interventions. by overmedicalizingnullifying the benefits of physical exercise. The necessary consensus. In this way, the authors who popularized the concept of ‘exercise as medicine’ explicitly recognize that exercise is not without risks. Even the WHO itself In its guides it maintains that inactivity is the greatest population risk, but there is fine print that must be taken into account: Exercise should be ‘prescribed’ starting with a low intensity, and not opt ​​for maximum intensity from the first day. This causes a person who has spent years on a couch to begin to carry a lot of weight, for example, and end up injured. Pain is not always bad, and the patient must be educated so that they see that fatigue from the gym does not have to be medicalized with pills. Patients with cardiac risk must be evaluated to prevent uncontrolled exercise from aggravating the situation. Be supervised. The conclusion in this case is that exercise is obviously necessary and without a doubt it is one of the practices that can prevent the appearance of many diseases. But we always have to be aware of what we do. Loading the body with a large amount of exercise from minute 0 can cause significant injuries or the aggravation of diseases that are already present. In this way, the possibility of being in a gym with trainers who can advise on the progression curve that should be followed can be an interesting idea to have the benefit of exercise without the consequences of doing it aggressively.

The US electrical grid does not support so many data centers so they have had an idea: disconnect them to avoid blackouts

by

One third of all data centers in the world They are in the US and that is putting a huge burden on the electrical grid. One of the consequences that consumers are noticing is the price increases on the invoice, But electricity operators already foresee another problem: blackouts. What is happening. They tell it in WSJ. The US power grid is beginning to become strained, with grid operators expecting blackouts during periods of high demand. The solution they propose to avoid this is to make data centers disconnect from the network and use their own energy reserves temporarily. The technology companies have not been amused and talk about “discriminatory measures.” Why is it important. In 2023, data centers already consumed 4% of all the country’s electricity and the forecasts are that by 2028 that percentage will increase to 12%. The electrical grid is not prepared to support so much demand and, although it is already expanding, the pace of construction of new data centers is faster. Network operators face a difficult dilemma: powering data centers while maintaining supply to consumers. ‘Kill switch’. PJM Interconnection It is the organization that oversees the energy market in the Midwest, where they have already suffered from the problem of price increases. The concern that blackouts will occur is on the table and PJM has proposed that technology companies create their own energy sources or accept that their supply will be cut off if the network becomes too saturated. They are not the only ones who have raised something like this. With demand expected to double by 2035, Texas passed a law last year that contemplates a ‘kill switch’ that allows large consumers, such as data centers, to be disconnected at times when the network is under “extreme stress.” What the technologies say. As we said, the companies that own these data centers have not been very happy with the proposal. The Data Center Coalitionof which companies such as Google, Microsoft and AWS are part, have stated that the proposal is discriminatory since data centers need a reliable and stable network. They also warn that depending on their own energy reserves could have a negative environmental impact, by forcing them to use solutions such as diesel generators. Waiting times. There is an intermediate scenario in which technology companies can obtain benefits if they accept these conditions. As the electrical infrastructure does not support so much demand, data centers have to wait several years to be connected to the network, normally between 3 and 5 years, although there have been cases up to 8 years. Southwest Power Pool, the grid operator in Texas, has offered data centers a deal: give them access to the grid sooner in exchange for agreeing to be disconnected during times of high demand. According to a recent study Funded by Google, data centers that have more flexible connections (i.e., those that build their own power sources and accept temporary disconnections) typically connect to the grid several years faster than those that do not. Bring your own energy. Despite the reluctance towards that off button, generating your own energy is the most realistic solution and the one towards which the industry seems to be moving. Google recently bought an electrical company in order to obtain its own energy. Others big tech Amazon, Microsoft, Oracle or xAI are also exploring create your own energy solutions such as natural gas and solar panels.

How the Sinaloa Cartel turned the marble industry into its methamphetamine logistics center

by

If Walter White had exchanged the New Mexico desert for the Mediterranean coast, his story would not have been very different from what the National Police has just revealed. in the series Breaking Badthe Albuquerque chemist hid his money under the sand and used a car wash to launder his “blue empire.” On the other hand, in the province of Alicante, the setting has been a marble industrial warehouse, an armored underground bunker and a statue of Popeye that, instead of spinach, kept the purest “crystal” of the Sinaloa Cartel. As if it were a script by Vince Gilligan, “Operation Saga” has revealed that the largest methamphetamine network in Europe did not operate from marginal shadows, but from the heart of the marble industry between Novelda and Monforte del Cid. He Heisenberg From this plot he decided that the marble blocks were the perfect container for the desires to expand the empire that Joaquín “El Chapo” Guzmán one day founded. The end of “Operation Saga”. The National Police, in a strategic alliance with the US DEA, has put the final lock on an investigation that began in 2023. According to the official press releasethis second phase has culminated in the total dismantling of a Spanish-Mexican organization responsible for turning Spain into the main hub of methamphetamine from the mainland. If in May 2024 the first phase already left a record number of 1,800 kilos of drugs seized, this new coup has ended with nine key arrests. The operation has managed to decapitate the infrastructure that the Sinaloa Cartel had woven between Tenerife, Madrid, Valencia and Alicante. A popeye 40 kilos. The logistics of the network were as ingenious as they were sophisticated. According to local mediathe narcotic was traveling from Mexico hidden inside imposing marble stones that were legally imported. Once in Spain, the organization used the business structure of a well-known marble worker in the area to move the drugs. We found the most surreal example in July 2024. The police intercepted a statue of Popeye, five feet tall and in metallic colors, bound for Tenerife. Its base was not solid metal, but contained 40 kilos of methamphetamine. The recipient, a “historic drug trafficker” on the island, was waiting for the shipment without knowing that the figure had been under police surveillance for months. This seizure made it possible to confirm that, after the 2024 coup, the organization was trying desperately refinance. The bunker and the salary of silence. Civil engineering put at the service of crime reached its zenith in a Novelda warehouse. There, the agents They found an underground bunker hidden under a heavy steel plate and a large stone block, where almost 3,000,000 euros in cash were kept. While the money was accumulating in Alicante, in the Madrid neighborhood of Malasaña, the organization supported a member of the Sinaloa Cartel “in reserve”. This man lived in a semi-cloistered regime in an apartment from which he barely left. He received a salary of 2,500 euros per month exclusively in exchange for his silence, since he knew the details of the entry of the 1,800 kilos of the first phase. A global drug network. The logistics brain was not at street level. The leader of the drug transporters, a Spaniard with a record of crimes against property, coordinated movements between Mexico and Spain through criminal teleworking from Dubai. From there he supervised not only the glass, but also secondary shipments, such as a 38-kilo shipment of marijuana intercepted in Finland. But why Spain? The answer lies in waste science. a study about wastewater (analyzing metabolites in urine) is the definitive tool to measure actual consumption. Although the consumption of methamphetamine in Spain is lower than that of cocaine, EUDA studies place Spain and the Netherlands as distribution hubs. In areas like Euskadi, for example, records of amphetamines in wastewater already show peaks that are eighty times the national average, an unequivocal sign that the market is there. The end of one era (or the beginning of another). The operation, directed by the Investigative Court number 6 of the National Court, has also seized seven luxury watches, geolocation devices and ammunition. With this, the Police consider that the most powerful criminal network of synthetic drugs in Europe has been dismantled. However, as Commissioner Alberto Morales warnsSinaloa’s persistence is legendary. Since 2009 they have tried to settle in Spain in every possible way: from “Chapo’s” cousin detained in the Palace Hotel in 2012, to the drug laboratories of “Los Chapitos” dismantled in Toledo in 2024. Today the Novelda bunker is empty and Popeye rests in the Canillas police facilities, but the authorities are clear that the “European dream” of the Mexican cartels is far from over.

Neptune’s closest neighbor is Mercury

by

There is information that we have stored in our heads since we learned it, such as prepositions or the planets that make up the Solar System. And that has its handicaps: having to enumerate the list to get to what interests you or if you are already a few years old, finishing the string of planets with Pluto. Old spoiler: Pluto was demoted in 2006, despite the fact that there are scientists who they question the definition of a planet and therefore, its appearance or not on that list. What is the closest planet to Earth? Faced with that question and with the temptation to recite the burned-in list, many people will probably say Venus and just as many will say Mars. Reality has its substance and although the situation changes frequently, it is generally considered that the correct answer is Venus. In fact, taking a look at the distances between each pair of planets We would reach that same conclusion. Well, yes, but no. Mercury is the winning horse. To NASA It refers to Venus as “our closest planetary neighbor” and although this is true if we stick to which planet is closest to Earth, it is not true if we are interested in knowing which planet is closest on average. Here things change and have a new winner: Mercury. Mercury is the innermost planet in the solar system, but on average it spends more time near Earth than Venus. What’s more, Mercury is on average the closest planet to all the other planets in the Solar System. How is the proximity between planets considered?. The usual method is limited to subtracting the mean radius of the inner orbit from that of the outer orbit. Thus, the average distance between Earth (1 AU) and Venus (0.72 AU) would be 0.28 AU. When they are furthest away, Venus is 1.72 AU from Earth. Although it is intuitive to consider the average distance between each point of two concentric ellipses as the difference of their radii, in reality that difference only determines the average distance of the closest points of the ellipses. A more precise mathematical method that considers time. The average of both scenarios above improves the calculation, but is still imprecise, they explain scientists Tom Stockman, Gabriel Monroe and Samuel Cordner. So the American Institute of Physics devised a more precise mathematical method that averages the distance over time of the planets and in this scenario everything changes and not only for the Earth, but also for all the planets. The method in question is called point-circle (PCM) and models orbits as concentric and coplanar circles. Since the planets spend the same time at each point in their orbit, the average distance can be calculated by integrating all possible positions. Using this method, Venus is an average of 1.14 AU from Earth and Mercury is only 1.04 AU. As they explain: “We observe that the distance between two orbiting bodies is minimum when the inner orbit is the smallest. That observation gives rise to what we call the whirly-dirly corollary (a reference to an episode of the series Rick and Morty): for two bodies with approximately coplanar, concentric and circular orbits, the average distance between them decreases as the radius of the inner orbit decreases.” The checks. This research team ran a simulation that calculated the position of the eight planets over 10,000 years and recorded their distance. The results differed by 300% compared to the traditional method, but less than 1% compared to the point-circle method. Mercury is the closest to all. This discovery not only affects Earth. In fact, it can be generalized to any pair of bodies with approximately circular, concentric and coplanar orbits. With this method, the average distance between two bodies depends on the radius of the inner orbit and the smaller the inner orbit, the smaller the average distance. In short: Mercury is the closest planet to Earth, but also to Neptune and even the degraded Pluto. This finding, beyond changing the paradigm of how to consider distances between planets, may also be useful for estimating communications with satellites.

A simple gadget is making a species evolve live and direct: hummingbirds

by

During the late 1820s, Rene Lesson visited many times the ornithological collection of François Victor Masséna. Every morning, he crossed the doors of the Parisian palace of the Dukes of Rivoli and immersed himself in the more than 12,000 species they had accumulated there. Some say he fell in love there. Sometimes, just before immersing himself in work, he would come across a very young woman Anna d’EsslingMasséna’s wife. Lesson, who was well aware of his social situation, never said anything; but in his papers he described Anna as “a woman of exceptional beauty, elegance and education.” I imagine that, for this reason, when he discovered the amethyst-headed hummingbird among the Duke’s specimens, he thought of her. I imagine that, for this reason, Lesson named it after him. What I can’t imagine is what the French ornithologist would think if we told him that we were “evolving” the hummingbird he gave to Anna until we changed it forever. But that’s how it is. The evolution live and direct. I came to this story (and Global Change Biology study which supports it) thanks to a bluit by Carlos Cabido. It is, as the evolutionary ecologist says, “another case of rapid evolution that has generated observable adaptive changes in a very short period.” The “smoking gun.” But let’s start at the beginning: researchers at the University of California Berkeley analyzed the population expansion and the morphological changes in the beaks of hummingbirds in relation to a very specific device: the feeders that, since the 1930s, have been used on the west coast of the United States. These are simple sugar water dispensers, but (always according to researchers) they have caused a series of very striking changes. What changes? On a regional and temporal scale, “the density/use of feeders appears as the best predictor of population expansion”; well above other variables analyzed. This means that the installation of these dispensers is the key to the expansion of hummingbirds. Linked to that, researchers they observed significant changes in the morphology of the beak: it has become longer (to better access the feeder) and sharper (in a context where territoriality is becoming more important because it is linked to a very concentrated resource). And all this in a couple of decades. That is, in about ten generations. Why is it important? Above all, because it is one more example that a cheap, massive and standardized device (if it creates a new food environment) can reconfigure body structures and behavioral repertoires. And, beyond all that, because it shows that, if environmental change is intense and sustained, natural selection works like a shot. However, all that glitters is not a hummingbird. In fact, Anna’s hummingbird is almost an exception. As far as we know, countless hummingbird species They are suffering (and big time) the changes linked to the Anthropocene: although the Anna is growing, its first cousins ​​are in clear decline. And yes, it is our fault. Yeah this study shows that we have great power to change nature, the overview reminds us that “with great power comes great responsibility.” Image | Robert Bottman In Xataka | The domestication of cats remains a mystery.

when Albacete set the record for a capital at -24ºC

by

Europe has started 2026 with cold. Very cold. But even the icy winds that have hit part of the continent and the peninsula these days, sinking the thermometer below 15 ºC, they pale when compared to what Castilla-La Mancha experienced in the early stages of 1971. That year left a meteorological curiosity in Albacete, a record that has remained unbeatable since then in the historical records of the Aemet: the coldest temperature ever remembered in a provincial capital, neither more nor less than -24 degrees. The most curious thing is that not even that value (more typical of other Siberian latitudes) marks the record of cold registered by the agency in Spain. “Extreme values”. The Aemet not only helps us know the weather in the ‘future’, to know if this week it is going to rain or be sunny, we should dust off the winter scarves and gloves or we can give the anoraks a break. The agency also allows us to know what the weather was like in our cities 10, 30, 50 years ago… even more, almost a century ago, something that is possible thanks to its series of “absolute extreme values”. The service (available online) details the record measurements associated with each weather station since 1920. What does that mean? That we can know the record values ​​of rain, temperatures, snowfall or gusts of wind captured by each of the stations managed by Aemet in the 50 provinces of Spain, in addition to the cities of Ceuta and Melilla. Their data must be handled with some caution (especially in comparisons) because they are subject to important handicaps. Aemet does not clarify, for example, whether all the sensors have been operational for the same amount of time or how long each one has been working. Another key fact is that within the same region (or even locality) there may be thermal differences or significant rainfall. It all depends on where the sensor is installed. A station located in a port area may collect very different values ​​than another located within the same municipal area but in the heart of the urban area or in a higher area, such as an airport. In fact, it is not strange that Aemet has sensors that collect information near the terminals. provincial capital lowest temperature Date Madrid -15.2ºC 01/16/1945 Barcelona -10ºC 02/11/1956 Valencia -7.2ºC 02/11/1956 Saragossa -11.4ºC 02/05/1963 Seville -5.5ºC 02/12/1956 Malaga -3.8ºC 02/04/1954 Murcia -7.5ºC 01/16/1985 Palma de Mallorca -10ºC 02/12/1956 Las Palmas de Gran Canaria 6.5ºC 03/27/1954 Alicante -4.6ºC 02/12/1956 Bilbao -8.6ºC 02/03/1963 Cordova -8.2ºC 01/28/2005 Valladolid -18.8ºC 01/03/1971 Victoria -21ºC 12/25/1962 To Coruña -4.8ºC 01/07/1985 Grenade -14.2ºC 01/16/1987 Oviedo -6ºC 01/07/1985 Santa Cruz de Tenerife 8.1ºC 02/22/1926 Pamplona -16.2ºC 01/12/1985 Almeria 0.1ºC 01/27/2005 San Sebastian -12.1ºC 02/03/1956 Burgos -22ºC 01/03/1971 Albacete -24ºC 01/03/1971 Santander -5.4ºC 01/21/1957 Castellón de la Plana -7.3ºC 02/11/1956 Logrono -11.6ºC 12/25/1962 Badajoz -7.2ºC 01/28/2005 Salamanca -20ºC 02/05/1963 Huelva -5.8ºC 02/17/1938 Lleida -15.4ºC 01/02/1971 Tarragona (Reus Airport) -8ºC 02/11/1983 Lion -17.4ºC 01/13/1945 Jaen -8ºC 02/11/1956 Cadiz -1ºC 02/11/1956 Ourense -8.6ºC 12/25/2001 Girona -13ºC 01/09/1985 Lugo -10ºC 12/23/2005 Caceres -5.8ºC 02/11/1956 Guadalaraja -11ºC 01/28/1952 Melilla 0.4ºC 01/27/2005 Toledo -14.4ºC 01/18/1945 Ceuta -0.4ºC 01/05/1941 Pontevedra -5.5ºC 12/10/1922 Palencia -14.8ºC 01/04/1971 Royal City -13.8ºC 01/03/1971 zamora -13.4ºC 01/03/1972 Avila -16ºC 01/15/1985 Huesca -13.2ºC 02/12/1956 Basin -17.8ºC 01/03/1971 Segovia -17ºC 01/06/1938 Soria -15ºC 12/17/1963 Teruel -21ºC 01/12/2021 One piece of information: -24ºC. Taking into account the above, the historical record of the Aemet leaves a curious fact, one that I remembered recently in X Vicente Aupí, popularizer and astrophotographer: on January 3, 1971 Albacete the thermometers dropped neither more nor less than -24º. The data was obtained at the air base and is interesting for several reasons. Not only is it the lowest value recorded in the city since records began, it is also the coldest confirmed in a provincial capital. Freezer records. The next lowest value among the provincial capitals was experienced by Burgos that same day (January 3, 1971), when the mercury dropped to -22. Vitoria and Teruel follow in the ranking. The first recorded -21 ºC on Christmas Day 1962, the second endured the same temperature on January 12, 2021. These are surprisingly low data, although in recent decades Aemet has reported a few measurements below -15º. Meteorological bulletin of January 3, 1971, when the station located in Albacete recorded a minimum of -24 ºC, a record value among the provincial capitals of Spain. Extract from the meteorological bulletin of December 17, 1963, when a minimum of -30 ºC was recorded at the Calamocha-VOR observatory station, province of Teruel. to stay at home. The most striking thing about January 3, 1971 is that the thermometer not only collapsed in Albacete. Another interesting resource that Aemet offers is the newspaper archive of the ‘Meteorological Bulletin’a part edited by the agency’s predecessors between March 1893 and well into the 21st century. On its website today we can consult practically all of its digitized issues from 1894 to 2007. Among them is the census of that Sunday, January 3, 1971. And what does it tell us? That day the people of Albacete were not the only ones who faced a wave of polar cold. Although the city took the cake, in Burgos they scored -22º, in Valladolid, Teruel and Daroca -19º and -18º in Cuenca or La Molina. Some of these values ​​were also obtained at aerodromes, just as happened in Albacete, where that day the thermometers they did not go beyond -6º. In all the provincial capitals of Spain, that day the mercury did not rise above 10 ºC, the maximum recorded in Almería, Cádiz and Castellón. The coldest day? Yes. And no. The figure for Albacete is a record among provincial capitals, but in Spain we have endured even colder days. At the end of 1963, the residents of a small town in Teruel saw how the mercury dropped until it reaches -30 ºC. That is the surprising minimum temperature recorded on December 17 of that year … Read more

Disney+ has discovered that Generation Z does not want to watch its two-hour movies. So he’s going to give them vertical microdramas

by

Disney+ has decided to join the battle for the viewer’s thumb. The company announced this week at CES that will incorporate vertical videos to its platform during 2026, a commitment to the format that dominates TikTok and Instagram. The news marks a strategic shift for a giant traditionally associated with the traditional (and horizontal) cinematographic experience. What does it consist of? If Disney previously sold large screens in dark rooms, now it is not exactly seeking to replace them, but rather to create a new habit: that opening Disney+ is a gesture as automatic as doing so with any social network. Netflix measures its impact in monthly viewing hours, but Disney wants what YouTube and TikTok already have: compulsive daily views. In an industry where engagement Everyday life has become the battlefield, Mickey and Spider-Man will learn to do choreography in vertical format. What will it include? Now, as explained by Erin Teagueexecutive vice president of product management, the plan aims for a feed personalized with algorithms that will mix news and entertainment. The raw material will be varied: from original productions designed for vertical format to recycled material from social networks and scenes from series or movies reformatted for mobile screens. Teague acknowledges that what they intend is to turn Disney+ into “a must-visit destination every day.” It is no longer enough to be the service where you can watch the latest season of something, but to be the one that you open without thinking, several times a day, just like you do with other apps that don’t even charge a subscription. where does it come from. The strategy does not come from nowhere. Disney had already tested the waters with the so-called “Verts” in the renewed ESPN application, launched in August 2025. Those vertical sports clips (highlights, quick analyzes, statements) functioned as a laboratory before escalating the bet to the rest of the Disney+ ecosystem. Rita Ferro, global head of advertising at Disney, commented in the presentation that ESPN had captured 33% of all live sports audiences during 2025 in the United States, leaving its closest competitor at 20%. The evolution of the vertical format. The vertical format has been redefining how we consume audiovisual content for years. Teague herself, before signing for Disney, worked for years on YouTube and witnessed from the inside how Google initially underestimated TikTok’s push. The answer (YouTube Shorts) was a long time coming, but when it did it changed many preconceptions: most of these short videos they end up consuming themselves on televisionsnot on mobile phones. The vertical conquered the living room, and that’s where Disney+ wants to be. Aside from this, Netflix tried publishing vertical anime videos in 2021, but never took the proposal beyond limited experiments. No competitor has yet found the formula, and Disney wants to be the first to get it right. Who has already done it. None other than Procter & Gamble, the multinational consumer products companyreinvent the soap opera and launch this January ‘The Golden Pear Affair‘, a “micro soap opera” of 50 episodes designed specifically for consumption on social networks, since its distribution will start on platforms such as Instagram and TikTok before migrating to its own mobile application. This is not advertising disguised as content: it is content designed from scratch to sell products: if the product placement classic interrupted the narrative, here the narrative is born to serve the product. Meanwhile, the fever of microdramas that conquered Asia a few years agoreaches other continents with production companies like TelevisaUnivision making compressed soap operas. The Spanish-speaking network has been exploring the “microdramas”ultra-brief versions of the soap opera format. and disney you know this works: Apps like ReelShort and Crazy Maple Studio have been dominating niche markets with sixty-second vertical dramas for years. Its model (free hook episodes, payment to unlock more chapters) has shown that addictive narrative works even atomized. These Asian platforms generate tens of millions annually with content that Hollywood would have considered impossible to make profitable a few years ago. Advertising implications. The vertical format is not just an aesthetic or generational issue. It is, above all, a new advertising space: Disney announced a metric that merges Disney’s own data with information from external providers, saying that the format was a very attractive space for advertisers. And it also introduced an artificial intelligence-powered video generation tool that allows advertisers to convert existing materials into renewed ads. It is no longer necessary to produce spots from scratch; just feed the machine with assets priors and brand guidelines. So now Disney’s recent deal with OpenAI does. acquires a renewed meaning. Transformation or concession. Teague openly acknowledged that “Gen Z and Gen Alpha aren’t necessarily thinking about sitting through two-and-a-half-hour long content on their phones.” Disney does not want to attract new generations to its classic catalog, but rather to speak in the same language as these young people who have always been its potential audience. For millions of users, cinema is no longer the basic unit of entertainment, and Disney has decided that, rather than compete with Netflix, it has to do so with WhatsApp, Instagram and TikTok.

We had been looking for an alternative to cement for decades. We just found it in seashells

by

The search for construction elements that move away from classic materials such as steel, concrete or cement makes sense from different fronts ranging from economics to sustainability through technical limitations. Without going any further, we can already see skyscrapers made of wood and some even compete to be the tallest in the world. Yes, wood is proposed as a serious alternative, but you can also give a twist to cement as we know it with a new old acquaintance: the shells on the beach. From waste to concrete ingredient. Seashells that are normally treated as waste can become a kind of substitute for the cement used for concrete, as a published study by the University of East London has concluded. in Construction Materials magazine. In fact, they can act both as a filling material and as a partial substitute for cement. Thus, microstructural analysis revealed that the shells, which are rich in calcium, help refine the porous structure of the concrete and promote the formation of additional binding compounds, that is, it even provides additional benefits in terms of performance. under the microscope. Scallop shells are composed by a range of 95 to 99% calcium carbonate (like limestone, the raw material for cement) presented in two crystalline forms, calcite and aragonite. The other 1-5% is the organic fraction, which serves as cement to bind the calcium crystals. The shells are a sort of biogenic limestone, chemically compatible with cement, which is still a hydraulic binder of limestone and clay. Up to 36% less cement. The process is also quite “simple”: grinding scallop shells to turn them into a fine powder suitable to replace part of the cement mixture. How much? Up to 36% without substantially altering the characteristics of the concrete. Why is it important. The partial replacement of cement with a natural waste material such as shells is an unexpected and novel solution to reduce the environmental impact of cement, currently responsible for approximately 7% of global carbon emissions. This percentage is so high not only because of the fuel required to heat the furnaces, but also because of the chemistry of the process itself. In fact, already has been experimented with ecological mortar. The person responsible for the study, the associate professor of Structural Engineering at the UEL and doctor Ali Abass contributes more context: “Concrete is everywhere and, consequently, its carbon footprint is enormous.” Regarding its applicability beyond the study, Abass is optimistic: “At moderate levels of substitution, concrete performs very well, meaning this solution could be scaled in real-world environments.” In addition, two problems are solved at once: “Millions of tonnes of shell waste are generated around the world every year, and most of it has no useful destination. If we can divert even a fraction into low-emission building materials, the environmental benefits could be significant. It’s a simple idea with real potential to transform part of the sector.” A giant step towards more sustainable construction. In short, the use of shells would allow us to cut significant amounts of CO₂ from one of the most polluting materials in the world and move towards more sustainable construction. In the absence of future industrial trials to support large-scale reliability, its adoption potential is notable, especially at a time of increasing calls for stricter environmental standards and scrutiny over carbon footprint calculations.

Science has investigated why we bite our nails or leave everything until the last minute: “controlled explosions”

by

Biting our nails until it hurts, bingeing on junk food after a stressful day either open TikTok just when we have to start workingit is not an irritating habit that we would like to erase from our daily lives. But the reality is that science is beginning to see these behaviors in a radically different way: as a protection strategy for the organism. The brain seeks survival. As pointed out by different experts such as clinical psychologist Charlie Heriot-Maitland, author of Controlled Explosions in Mental Healthour brain prefers to inflict controlled “microdamage” on itself rather than face a greater and unpredictable threat. And the premise from which affective neuroscience and evolutionary psychology start is forceful: our brain is not programmed for us to be happy, but it is programmed to seek survival. Which is precisely what we did thousands of years ago when we tried to hunt or flee from predators. Systems that are still very present in our genetics. A hypersensitive system. This threat detection system is hypersensitive today. In the modern world we do not have to flee from a predator, but criticism from the boss or the fear of failing in a project activates the same alarms that a predator in the savanna activated in our ancestors. And faced with this unbearable stress, the brain looks for an escape route that acts as a “safety valve.” This is what Heriot-Maitland calls “controlled explosions.” Nail biting. Why can something as absurd as biting your nails or picking your skin be “protective”? The key is predictability. And in a chaotic world and an emotional, abstract and difficult to manage threat, cause us a little physical damage (like biting a cuticle), causes the brain to divert attention towards a specific, real stimulus and, above all, under our control. In this way it works as a “costly signal”, since we prefer a small and known damage to cushion emotional pain that we perceive as potentially devastating. Procrastinating is not laziness. scientific literature speaks in this sense of the self-handicapping (self-limitation), which suggests that we put obstacles on ourselves to protect our self-esteem. This way, if you stop studying for an exam and fail, you can tell yourself, “I failed because I didn’t study.” It’s a small damage to your ego. However, if you study to the maximum and fail, the conclusion is much more painful: “I failed because I am not capable.” The brain prefers the narrative of lack of effort (microdamage) rather than facing the threat of incompetence that poses greater emotional damage to anyone. It is not exclusive to us. In nature, there are numerous social insects that resort to defensive self-immolation in order to save their colony, as we already saw. In our case, the mechanism is something like this: we sacrifice our current well-being, such as physical health, to reduce a perceived long-term risk. The problem is that this system is designed for life or death situations, not to manage the chronic stress of the 21st century. In this way, what began as a useful defense ends up becoming a self-defeating pattern that generates more anxiety than it relieves. How to avoid it. If we understand that modern nails or procrastination are defense mechanisms, the solution changes completely. In this way, modern therapies, such as Compassion Focused Therapy, They propose that the first step It is not fighting against the habit, but understanding the reason for its existence. The most important thing in this case is not to punish yourself, since self-criticism is perceived by the brain as other threatens more, which reinforces the need to resort to the destructive habit to calm down. In this way, if we generate security, the brain will not have the need to cause these “controlled explosions.” Images | Sander Sammy Tim Gouw In Xataka | Procrastination is one of the great temptations of the mind. There are techniques to avoid it, according to science

MG, Omoda and BYD close a spectacular 2025 and are among the best sellers

by

It was the last days of March 2023 when we traveled to the north of Madrid to attend the BYD launch. “Europe has had its eyes closed for a long time”they told us from the company. That felt like the arrival of the first Chinese brand to our country, the one that came to confront Tesla in the electric car. At that time, MG was already selling thousands of units in our country and there were minority alternatives but the arrival of a manufacturer that was approaching two million cars sold It was already more serious. Months later Chery would arrivewith Omoda and Jaecoo, but also Ebrounder the arm. Along the way, other minority brands such as Lynk&Co or Xpeng have also been bringing new models to the market. But the bulk of Chinese sales and impact in our country is concentrated in the three companies we have listed. MG is completely established in our country, BYD has completed its second full year (with a change of direction included) and Omoda, Jaecoo and Ebro have now established their offer. And the result has been very good for them. More models and more sales If the year of Chinese brands in Spain has been characterized by something, it is because have put more points of sale on the streetmore cars in those points of sale and, above all, more cars in the garages of your potential customers. At the end of 2025, in Spain the main Chinese brands have obtained the following results: MG: 45,163 units (growth of 46.78%) BYD: 25,556 units (growth of 373.87%) Omoda: 13,963 units (growth of 79.33%) Jaecoo: 9,728 units (growth of 785.17%) Ebro: 12,459 units (growth of 44396.43%, they only had one car available at the end of 2024) Are very striking data due to several factors: MG sold more cars in Spain than Citroën (34,286 units), with which it competes on price. And it sold more cars than classics like Ford (29,065 units), Nissan (34,711 units), Opel (26,549) or Skoda (42,387 units). BYD only sells plug-in hybrid and electric cars so its potential customer market is much smaller Omoda, Jaecoo and Ebro are three brands of the Chery Group but each of them competes with three or four cars that, in addition, can be stepped on in price but not in positioning. If the sales of the Chery Group are added, they exceed 35,000 units. Brand by brand If we focus on the approach of each of these companies, we must take into account that MG already has a wide range of vehicles but is managing to attract customers in one of the most complicated markets: that of the cheapest cars on the market. Almost half of the sales of the best positioned one are accumulated by the MG ZS, one of the most affordable options on the market that for just over 20,000 euros delivers the ECO sticker so sought after in a Spain with growing low-emission zones. This has been the first year with its hybrid version working at full capacity and that has been noticed. The same has happened with the MG3which accumulates more than 9,000 units and is its second best-selling car. He good result The MG ZS among hybrids can be seen on the list of best sellers. And, of the non-plug-in hybrids, the Chinese SUV is in seventh position, surpassed by a Peugeot 2008 that has accumulated just five more registrations and in a field where Toyota clearly dominates (three of the four best-selling cars in this segment are its). MG’s third big best-seller is a good example of where the strength of Chinese brands lies. The MG EHS is a plug-in hybrid that, again, conquers by price. It has managed to become the second best-selling plug-in hybrid of the year, surpassing a Toyota C-HR that could be the great favorite. But no one is offering as much size and equipment at a lower price among plug-ins than the Chinese brands. That’s why the BYD Seal U has been the best-selling plug-in hybrid. As we said in our testcosts the same as the Toyota C-HR powered by this technology but for a family it can be much more interesting. The BYD SUV is not the only Chinese one that sneaks into the plug-in hybrid. The Jaecoo 7 also has its market share, a model that has also focused on offering extensive equipment at a reasonable price, which has allowed it to position itself as the sixth best-selling vehicle of this type in our country. The appearance of all of them and the Omoda 9 and the Ebro S700 among the best sellers of December, it gives us a preview of 2026 where everything indicates that The plug-in hybrid is the other great asset of Chinese models for next year (after the entry range). In that low range, the Chery group has already begun to make room for itself with the Omoda 5 but hopes to hit the table with its hybrid version. The car not only has an ECO label, The SHS-H version is a hybrid with all the letters and a particular touch. Attractive price, a design that is being liked and extensive equipment are its great assets for next year. And if we look at BYD, the result can also be underlined as excellent. Surviving with electric cars exclusively was becoming difficult to grow quickly and they have put all their efforts into action. They tested the BYD Seal U DM-i and found that they have a gap among plug-in hybrids. Maybe your Signal 6 DM-ias a family sedan, has it more complicated but the BYD Atto 2 DM-i It is priced to be the most attractive option on the market right now. Despite everything, the company is the first of the mortals after Tesla. Elon Musk’s people continue to dominate the electric market in our country with an iron fist, where the autonomy/price ratio continues to outweigh the rest of the values. Of course, the … Read more
