Modern algorithms decide for us to see. YouTube is the last redoubt where the algorithm does not choose for you

by

The 2025 Internet is dominated by algorithms that seem to know each other better than ourselves. They were only missing Chatbots with memory than adding to your ability to read between the lines. In this scenario, YouTube is increasingly a beautiful anomaly. While Tiktok, Instagram or X drag us from one subject to another according to the whims of a system that optimizes engagement Pure, Google’s video platform maintains almost anachronistic respect for our choices. It is the last redoubt where what we are looking for still matters more than what makes us react. The difference is in Its algorithmic architecture. YouTube recommends mainly within the thematic ecosystems that we have already chosen. Tiktok, on the other hand, can launch us from vegan recipes to conspiracy theories at a time if that keeps our thumbs sliding. This thematic verticality It is not altruism, it is part of its business model: You need to maintain long sessions within specific issues, where segmented ads have greater value. Only its consequence is positive for the user. Or at least more positive than the rest. The best way to understand what makes YouTube different is to live it as a user. When I am looking for videos of Valencia, the algorithm keeps me in that world: post-part interviews, gatherings, montages of the best goals of the season and usually memories of a better past. It does not suddenly jump to polarizing politics or drag me to incendiary content it happens to provoke my outrage. YouTube respects the thematic ecosystem that I choose. Amplify our searches, do not try to manipulate us better. The user experience reinforces this sense of control: A prominent search bar. Channels to subscribe. Lists we actively build. A history that we can manage. They are vestiges of an internet where we sailed with purpose, not where we were navigated. It is also fair to indicate that YouTube belongs to Google, one of the great architects of the current algorithmic Internet. It is not immune to problems – the clickbait it blooms and its own attempts with YouTube Shorts They show that it is not above the market. However, it maintains a different balance. And the question is obvious: if this more balanced model works for the world’s largest video platform, why do the rest of the industry opt for systems that virtually annul our agency? YouTube also has serious problems. Their Rabbit Holes (Something like ‘Backgroundless wells’) They can take us on paths cobbled by radicalization. Its monetization system favors the extension and recurrence of quality. We are not facing a hero, but before a survivor who has found a niche where he prosper without completely eliminating our autonomy. In the end this this chronology of the evolution of the Internet. The web (yesterday Gloria, today survival) was originally a space where we chose our destinations. Today algorithms decide for us. YouTube retains vestiges of the previous model while adapting to the new one, becoming a kind of “Internet inside the Internet.” This “limited algorithmic autonomy” allows something not only good, but almost sacred: predictability. We can anticipate what we will find, creating a more satisfactory experience. It also allows the fragmentation of communities focused on specific interests, without forcing that everything competes in a single Feed homogenized, which is The great evil of the current X and the perennial identity of Tiktok. YouTube is not perfect – no one is – but it makes us question if we can design platforms that serve users who want to enjoy healthy, without being hooked or dragged where they do not want, and not just advertisers. YouTube, with all its contradictions, is a sign that an intermediate path is possible. Where there is some algorithmic manipulation (it is the market, friend), but that coexist with the total user agency.

consumes much more electricity than data centers

by

In 2022 in the air conditioning it represented 7% of world consumption of electricity. And its pressure on electrical infrastructure does not stop increasing year after year. On the other hand, data centers will be responsible for 10% of the increase in energy demand until 2030. Air conditioning will contribute a much greater percentage. These estimates formalized them in November 2024 International Energy Agency (IEA) and clearly reflect that the energy consumption of air conditioning devices is more worrying than that of data centers. The rise of artificial intelligence (AI) that we are living has triggered the proliferation of these facilities in the US, China, Japan, Singapore, India, Germany, Netherlands or Ireland, among other nations, but, in theory, the forecast of the IEA has taken it into account. And also that air conditioning devices have to respect an increasingly strict regulation in energy matters. However, as Casey Crownhart points out, a journalist specialized in the behavior of the weather of MIT Technology Reviewhe global warming Play against us. Refrigeration is the authentic monster of global energy demand In 2016 there were just under 2,000 million air conditioning devices throughout the planet. However, in 2050 the IEE estimates that there will be about 6,000 million of these devices. This strong growth is the consequence of the constant increase in the number of cooling degrees per day derived from global warming. In 2024 the cooling degrees per day were 6% higher than in 2023, and nothing less than 20% higher than the average of the first two decades of this century. The countries that invest more energy in the air conditioning devices are precisely the three most populated on the planet: India, China and the US The countries that invest more energy in the air conditioning devices are precisely the three most populated on the planet: India, China and the US. However, the impact of this energy demand is global. Besides, not only does it matter How much electricity consume air conditioning devices; It is also very relevant When this energy demand occurs. In fact, in the US these devices represent up to 70% of consumption in those time slots in which it is more hot. This behavior submits the electricity to enormous stress, although this voltage oscillates as the hottest hours give way to the freshest moments of the day. Whatever it is is evident that It is very important to innovate in the field of cooling technologies. The presumable proliferation of air conditioning devices over the next few years will require that each of them consume less energy. Even if it’s just a bit. A minimum improvement in a huge park park can make a big difference. The good news is that Innovations are coming in the technology of cooling devices that invite us to look to the future with reasonable optimism. Desiccant cooling systems use special materials that absorb moisture to cool spaces in a more efficient way. And heat exchangers containing not only air conditioning devices, but also refrigerators or heat pumps, are increasingly efficient. It seems that this is the way. Let us trust technological development to help us solve this enormous challenge.

The more and less reliable car brands of 2025, in a graphic dominated by Japan and with a surprise: Tesla

by

Buying a car is A authentic headache. It is logical if we consider that, usually, after the house, the purchase of a car is the greatest expense we make. There are many variables to take into account (motorization, securitymore or less screens …) and something that should be seen are the lists of the most reliable cars. There are several, Like those of Consumer Reports Or JD Power, who help us make the decision. And, precisely, in this graph elaborated by Visual Capitalist We have the list of the most reliable brands of 2025 according to one of these databases. JD Power. First of all, let’s see the context of this company. Founded in 1968, it has been specialized in handling big Databases that collect consumer data in various industries. One of them is that of the car, where they analyze all those data to prepare reports with achievements such as the discovery of a defect in the design of the rotary engines of Mazda in 1973, something that forced the company to remedy. In the automobile segment, they publish several lists, being one of them that includes the general degree of satisfaction of the owners of the different brands. On this occasion, it focuses on the United States, but as is the case in the Consumer Reports lists, although the US market is slightly different from the European, many of the brands and models are common in both markets. PP100. To understand the list, you have to know that the number of problems per 100 vehicles is detailed (problems per 100 or PP100) after three years of property. For example, in the Last year listJD Power collected the response of more than 30,500 people from cars bought in 2021 and, after three years, detailed the problems belonging to nine categories: Abroad Inside Seating Driving experience Air conditioning/air conditioning Controls Infoentrate system Engine Driving aids The best. Going to the list, we have a recurring company in the first position: Lexus. In different consumer surveys, Toyota’s luxury brand has been crowned as the company that has the most degree of satisfaction among its customers. In this case, although it has more errors than in the list last year, it continues in first position. The American Buick is the second and, thirdly, Mazda advances to Toyota. Nothing surprising: Japan continues to lead in the high satisfaction positions, but others like General Motors manage to sneak because they have varied the most with respect to the previous period. The biggest changes. Precisely, there are several changes in the list marked by that improvement or worsening in front of the 2024 survey. Mazda is one of the one that improves the most with respect to the last year, reducing its PP100 by 24 points. Ford reduced it at 31 points and Tesla starred in the biggest change by reducing it by 43 points. There are also changes worse, such as that of the aforementioned Toyota, Alfa Romeo, Hyundai, Acura or Jeep, something that surprises less if we see recent movements of the company in American territory, with policies that are not liking and other determining factors for this list. Worse. The really interesting, beyond the brands whose reputation improves or worsens in recent months, is the fact that, globally, the average errors per 100 vehicles has reached, according to JD Power, its highest average since 2009. This is curious because it was the year immediately later to the financial crisis of 2008 and the manufacturers may cut in components, but cars analyzed in 2024 They are built during the Covid-19 pandemic, which points to a correlation between a crisis moment and an increase in vehicle failures. More technology, more problems. The more options a device has, the more possibilities there is something fail. It is something that surely you have heard: do not buy you a washing machine because it surely fails more than a washing machine and a separate dryer (insert the example you want with a microwave-shock or whatever). Well, in the case of cars, according to JD Power reports, half of the main problems of the entire industry are related to the great novelty of recent years: integration with smartphones and systems ANdroid Auto and Apple Carplay. In fact, in surveys, 56% of users claim that they have not noticed improvements even after updates and that, the more software related to the Infoentrate It has the car, there is more likely that something fails. Obviously, Millions of cars are sold a year And many have that integration, but also owners or solutions such as Android Automotive and the units that fail represent a small percentage. But, in an industry that becomes more and more in this and Use of screens (With brands that are already reculating), It is normal for more mistakes of this type to appear. Choosing a car now does not go only motor or design, but also of stability in the software, and it is convenient that we keep it in mind when choosing.

This bridge built by China is so high that two Eiffel tower fit under it. And they have built it in just four years

by

We have been having bridges from prehistory. From that tree That someone would use to connect two sides to the majestic Roman bridges, humanity has evolved while doing the bridges he built. The more recent techniques They allow us to connect extremes that are separated by tens of kilometers, but Talk about bridges It is currently looking at China. They not only have The longest maritime bridgebut also the highest in the world. It is the Bridge of the Grand Canyon of Huajiang and the most surprising thing is not that under it two Eiffel Tower enter one over another, but that it has only taken four years to lift it. Necessary. The Gran Canyon of Huajiang is located in the province of Guizhou. It is an area that, traditionally, has been isolated from the rest of the area for a reason for weight: more than 90% of the territory is mountainous terrain that hinders communication. For centuries it did not have much importance for the rest of the empire, but China has been raising infrastructure (and also excavating) to demolish those geographical barriers. Puzzle. The objective of the government is to connect rural areas with urban centers and, in this case, you had to get the Liuzhi-Anlong highway to raffle the mountains to speed up transport times. The only way was through a bridge, and after an analysis period, in 2022 They started The construction of the great bridge. It was not going to be simple: it should not only be at a considerable height, but to have a length of almost three kilometers. And the problem was not so much to create the suspension bridge, but to raise the necessary materials. To do this, implemented Advanced technologies to raise steel beams by up to 215 tons of weight and, despite the difficulties in the field, the works have gone at a pone rhythm. To all fuse. That is what usually attracts the attention of these Chinese infrastructure that, weighing some exceptions such as half -building abandoned skyscraper For years, they are an example for the rest of the world. The works advance with speed and, if At the beginning of this year We already saw the two towers of 262 and 205 meters on both sides of the bridge, as well as the cables of 9,000 tons each, now we observe that they have already built the section that joins the ends. The length Total of the bridge is 2,890 meters and the main section, which is among the towers, has a length of 1,420 meters that positions it not only as the highest bridge in the world (it is 625 meters from the ground, reaching the end of the towers at 776 meters), but as the longest hanging section built in the mountainous area. The comparison with the height of the Eiffel Tower is interesting, but almost two Empire State Building would also enter. The technology used in construction is also interesting. For example, when the concrete pour, Guizhou Bridge Group builders devised a system of pipes that pump cold or hot water depending on the outer temperature to ensure that fresh concrete dried in the best possible conditions to avoid cracks. And, to guarantee maintenance, the cables have sensors that measure vibrations or wind intensity to offer reports on the state of the hanging section. Impact. In January of this year, it was reported that 75% of the project had been completed, but in recent months we have seen how they have advanced so much that it is practically only missing and installing the security elements. The idea is to open at some point in June this year and, once open, will allow Crossing the canyon in just a couple of minutes when before it was something for more than an hour. But beyond all this, the most impressive thing is that they have been able to build an infrastructure in a very complicated place and condense 439,000 m³ of concrete and 49,000 tons of steel in just four years. And the cost? In theory, 280 million dollars that are difficult to estimate whether they will recover by joining rural areas, but as infrastructure and demonstration of strength, the Huajiang Grand Canyon bridge is imposing. And will remove the record from the highest bridge Lege’s, also in China.

More and more young in Spain turn to laser machines to erase tattoos

by

There are situations that are no longer forever, even if you record them with ink. Although a third of the young Spaniards carries at least one tattooa trend in social networks It is showing that it is increasingly common to erase what one day was permanent. The “forever.” That is one of the most common phrases when you get a tattoo: “Are you sure? It’s forever.” In recent years, tattoos have popularized so much that Spain occupies The sixth place in the world With more tattooed people, and any event It looks like a good idea. However, according to A study by Lutronic PBSManufacturer of medical-aesthetic laser devices, in our country 60% of the people who tattoo regret it. The most common profile in this trend are women between 35 and 50 years old. And it is not an isolated phenomenon: An American investigation Pew Research showed that one in four people regrets at least one of his tattoos. Examples. This is the case of Natalia, 35, who has asked not to reveal her real name. She decided to erase the micropigmentation eyebrows due to the misinformation about this treatment. When he made them, they told him that it would be semi -permanent, but in the end it turned out to be like a tattoo. As she herself, there is no harm that for good does not come: when looking for a center where to eliminate micropigmentation, she also took the opportunity to erase her first tattoo, which “had nothing to do with it.” The story of that first tattoo dates back to his 18 years: “He was too young, it was more as a impulse of rebellion,” he explained. Over the years, more tattoos were made, but he has assured that “it has nothing to do with my style.” It is easier to do so than eliminate it. “The tattoos ink is deposited in the dermis, the second layer of the skin, because its molecules are too large for the body to break down,” Expert Goergen explains CNN. Laser devices emit rapid energy pulses that fragment the ink into smaller particles, which the body processes through the lymphatic system. In safe hands. So it is essential to have a good professional when making a tattoo. In the case of Sara, 30, who also wants to preserve her identity, her tattoo was performed by a person who considers “a bit inexperienced.” He does not like how he looks or how the tattoo feels in his ankle: “In the background I feel sorry to erase it. I did it with 21 years with money that I had saved, but it is like bulky, as if I had not healed well.” Sara consulted with a dermatologist who told him that the ink could have crossed the surface layer of the skin and that it would be advisable to eliminate it as soon as it could. This situation resembles a Swedish preliminary study, conducted with 11,000 people, which suggests that those who have tattoos They have 21% more risk of developing lymphomas compared to those who do not understand it. A good team. It is important to keep in mind that the process of removing laser tattoos, such as Q-Switched, requires specialized training. Natalia was clear: he thoroughly investigated and specifically sought that team, considered one of the most effective for erase. According to the Spanish Society of Aesthetic Medicinethe incorrect use of these equipment, poorly regulated or applied by unprepared people, can cause serious adverse effects, such as burns or scars. In addition, the organization complaint work intrusion and lack of regulation in these cases and others of aesthetic medicine. How many sessions do you need? Although there are clinics that promise to eliminate a tattoo in a single session, experts from the IML Dermatological Clinic They have warned that this is only possible in very specific cases (very small, old tattoos, with black and shallow ink). The most common is to require several sessions, separated by weeks or months. And yet the process is not exempt from complications. The least visible of the process. Jayne Foo, Singapore financial consultant, is part of a growing tendency of Influencers that shares your experience with aesthetic clinics to show the “before and after.” In his account he explains that he has had open wounds, huge blisters and extreme itching. In his networks he confirms that it is not so simple since you have to take precautions and avoid the sun. In addition, she warns that many videos in networks can be misleading, since they show what is known as frosted effect, which seems to clarify the ink immediately, it is only a temporary reaction that lasts about 15 minutes. An explosion to reverse the ink. Under him Hashtag #Tattoremoval on Instagram and Tiktok, more and more people show their tattoo elimination process. The influencer Claudieta, with more than two million followers, He has confessed: “Never make a tattoo at a time that you are bad psychologically.” In this context, and recently, A fans account of the actress Amanda Bynes a video has uploaded how a tattoo of the face is being erased, adding to the Trend viral. In the end a tattoo is an choice of life. A study revealed that the most impulsive people tend to tattoo more. But, as the interviewees have told us, what hurts is not so much impulse, but the process of reverse. Be that as it may, decisions are free and there is always time to change. Sometimes, erasing a tattoo is not forgetting the past, but accepting that it is no longer part of the present. Image | The Dame and Jayne Foo Xataka | The tattoos were always among us.

No one in the world knows what the hell do with mobile phones in classrooms. Not even scientific research

by

Imagine two students of a similar level doing exactly the same attention and memory test. Imagine, in fact, there is only one difference between them: one has the mobile in sight. It is silent, in a corner of the table, with the sound off; But it is in sight. The other student, before starting the test, had left it in the next room. I would ask you to imagine who would get better results, but it doesn’t make too much sense. A team from the University of Chicago and He studied it in detail. There is nothing surprising in this mental experiment, the results coincide with our prejudices: The student who sees the mobile will get worse results. It is something, also that connect directly to our experience real, with Our Fomowith Our “dependence” to mobile. How are we not going to worry about the damage made by these technologies in the classroom? How will the smartphone not become a first -order educational problem? And that is precisely the problem: that if we stay on the surface of the problem, in the social and political debate, we find a Spectacular political consensus (with several Autonomous communities prohibiting them from hype and saucer); But if we deepen the scientific fund, the problems begin. Life is not summarized in an experiment from the University of Chicago. So, we have wondered what really happens in a school when we prohibit mobile phones? What experiences have other countries and colleges that have already taken measures? Why is there no clear consensus about what to do? What does the experience say? Verkeorg The scenes are almost a cliché: kids looking at the mobile phone, notifications that interrupt classes, parallel chats commenting on what happens in the classroom, bullying, anonymous messages, worried families, decentralized students … With all this in mind, it is not surprising that dozens of experts, activists and parents warn of the negative consequences for learning associated with mobile use. In fact, with all this in mind, it is not strange that Many countries have begun to take letters In the matter: one in four countries It has regulated the use of mobiles in school. The list is very long. If we only focus on our geographical, cultural or development environment: they have done so places like France, Italy, Luxembourg, Portugal, Canada or Australia. The first country to do so, in fact, was Italy. In late 2006 and early 2007, several incidents impacted fully on the country’s public opinion: from a group of students who recorded bulling another student with disabilities to another in which several students were recorded sexually harassing a teacher. That led the government to prohibit mobile in class. Unfortunately, its implementation was complex and there are not many data on its impact. What we do know is that in 2022 the Ministry of Education announced its prohibition againRecoding that (although no one paid attention to him) the measure had been in force for 15 years. We also know that by then, many more Páisses had regulated the matter. France approved its prohibition In 2018. In a similar situation are Luxembourg, Portugal and Sweden. In addition to Bavaria, the Swiss vaud canton, Ontario, Various states of Australia and dozens of school districts in the United States They have done the same. In 2023, Holland and the United Kingdom They said that it would also implement prohibitions From the following year. How have they done it? As we will see, this is the central question. First because, as Maria del Mar Sánchez pointed outProfessor of Educational Technology at the University of Murcia, none of these regulations has managed to homogenize the situation. If we approach what really happens in schools, “We will find great diversity“ Sánchez says. And this makes it difficult to apply, measure and study the consequences. The best example of this is Norway. In 2024, a report He explained That the prohibition of mobiles in classes had achieved a 60% reduction in consultations by psychological symptoms in adolescents, the decrease in cases of bulling and a significant improvement in the academic results of the girls. In addition, the effects it shows are much more intense on the low -income population. The curious thing, however, is that Norway I was not doing anything nationally with mobile phones. What was doing something was with bullying. Just coinciding with the period studied, the Nordic country was underway A series of changes To reduce bulling. The result is that, little by we are realistic, we will have to recognize that confusion is enormous. And is Spain? Being an autonomous competition, until recently each autonomous community and each educational center has decided on its own. As it seems, Galicia was a pioneer: In 2015 he published a decree prohibiting phones in class and, at the end of 2023, he also took a more vet during recess, dining room and entries or outputs of the center. Behind her (and in recent years) almost all communities have gone behind. But, again“one thing is the political and the holder and another the reality that he reaches the centers.” To the point that while Autonomic decrees were reformed To accommodate more hard disciplinary approaches, in others pilot projects to use mobiles were introduced as didactic tools. In short, Spain has been one more. Of course, it is important to note, however, that as Jose César Perales, professor at the University of Granada, explained in practice “the prohibition of mobile phones for non -educational use during school hours It was already the usual In most centers “that is, the most important change in recent years is that this prohibition is being made in a generalized way. In experts like Laura Canois part of a political response to the ‘state of opinion’ on the impact of technology rather than a clear will to intervene educationally in the huge list of problems That has contemporary youth. What does science say about all this? Let’s talk about academic performance Pabak … Read more

Buying a mobile in China is a brutal savings compared to Spain. The question is whether it ends out expensive

by

Mobile prices They have shot themselves, a lot. The High Premium range Round the 1,500 euros, the high range of 1,000 and it is not strange to find mid -range for about 500 euros. This has fired a fever for reconditioned and used mobiles, but also opens an interesting door in a crucial market in Spain: that of Chinese phones. Xiaomi is absolute king in Spainand manufacturers such as Vivo, Oppo and Honor Copan the Top 10. In not a few cases, these phones arrive in our country with cut -out specifications with respect to the Chinese variants. We will try to dissipate that fog around the purchase of mobiles in its Chinese version, outside the traditional distributors that sell the European and global versions we know. Hardware of Chinese VS European Before delving into the purchase process, it is convenient to know what they differ (and why they do) Chinese mobiles with respect to Europeans, since it is not minor details that separate some proposals from others. The battery. If we attend to recent releases, such as the Xiaomi 15 Ultra or the Magic7 Pro Honorthere is a key difference in the Chinese variant: it has much more battery. In Europe we receive practically the same model, but with a quite lower battery capacity. Reason? One: the costs. In the specific case of batteries, the new generation of Silicon-carbon with capacities of 6,000 or more milliamps hour It is especially expensive. Chinese manufacturers sell at a price in their native country, but import telephones to Spain has numerous costs related to transport, fees and taxes. Xiaomi herself recognized us that, if they wanted to continue bringing mobiles without raising prices, They had to cut off somewhere. The software. This is not the only difference we find and, sometimes, the Software differences They are especially relevant. This is the case of Vivo, who sells its phones with A -Ecuchos in Europe and with origin in his native country. OnePlus does the same with Oxygenos In Europe and color in China (although, for practical purposes, they are exactly the same), and Huawei is the most extreme case of all. In Europe, Emui, in China its own operating system, Harmonyos. In addition to not having Google services in China, these software differences can generate important incompatibilities with mobile payment services through NFC, and even HDR content reproduction in Netflix, since there are certain Google certificates that are not available in Chinese variants. The camera. Although camera hardware is usually identical regardless of the mobile version we buy, the image process is usually quite different. Manufacturers adapt how to process the final photography depending on the market to which the phone is intended. Sometimes they succeed, sometimes not so much. This is the case of the living X200 Pro, whose Chinese version Take better photographs than the global Hardware equality. Connectivity. If you buy a mobile in its Chinese version, you may suffer some problems related to connectivity. Yes, all 5G Chinese mobiles can use 5G in Spain, but there is a fact to take into account: bands. In China the same 5G bands are not used, and you may end up buying a phone that lacks crucial bands. What are these bands for? Mainly, so that you have good coverage in complicated areas, such as rural or interior. Some of the most used bands in Spain are not used in China. Mobile payments. Paying with the mobile is a basic, and some mobile phones with Chinese rom have serious problems to get it in Spain. This is due to the lack of native Google services and certification problems such as Play Integrity API. How much we save buying the mobile in China If the question is how much it saves buying a mobile directly from China the question is … big money. Technically at this price we should add VAT and customs costs. The reality is that Chinese stores are responsible for adjusting the customs statement so that we do not have to pay (generally) nothing extra. Even if you have to pay an extra tax, it would continue to account. In some cases, buying the mobile from China costs almost half, a very point to take into account if we are willing to face the small inconveniences we have mentioned above. The questions to be asked when buying a mobile from China Well, we already know that a mobile purchased in China will arrive with Chinese Rom (yes, sellers usually pre -installed Google services so you can use all your apps without problem), which you may miss any band (something you can check in your list of Specs), which you will save a lot of money and may what you are buying is even better than the global model. Now it’s time to answer some extra questions. How long does a mobile take from China? This will depend completely on the store and its shipping method, but this has ceased to be a problem for years. If the store is solvent you can have the mobile at home in less than a week. In the worst case, the waiting time is usually two to three weeks. What guarantee does a telephone bought in China have? If you buy a mobile outside the European Union, the guarantee depends completely on the seller. In recent years, most stores have put the batteries, and offer repair guarantees between one and two years. Of course, we will pay the shipping costs, and sending to China is not especially cheap. What version am I buying? Depending on the version we buy, the phone will have hardware and software characteristics. For example, if we buy an Xiaomi with Global Rom from China, we will have a phone with the best of the European version at a much lower price. If we buy the version with Chinese ROM, we will have a phone with an English system and some problems. It should always be assured which exact … Read more

Drinking too much affects our brain. And its effects are not far from those of a brain injury

by

We know that alcohol is a risk to our health Even in small doses. However, it is also known that the problems associated with alcoholic beverages grow significantly when we exceed the limits of what we call “moderate consumption.” Like a brain injury. A new study has observed That excessive alcohol consumption was related to the appearance of hyaline arterosclerosis, a disorder linked to brain lesions. The team highlights that, the association observed between alcohol and disorder should not be understood as proof in itself that alcohol is causing brain injuries. “Severe alcohol consumption is an important global public health problem linked to an increase in health problems and death,” pointed in a press release Alberto Fernando Oliveira Justo, co -author of the study. “We observe how alcohol affects the brain according to people age. Our research shows that excessive alcohol consumption damages the brain, which can lead to memory and cognition problems.” Hyaline artosclerosis. As explained by the study responsible for the study, the Hyaline artosclerosis It is a disorder that causes narrowing of some blood vessels, which makes them thicker and rigid. This in turn makes it difficult to flow from blood and therefore end up causing damage to the brain. This disorder can be originated in areas of the brain where there have been damaged injuries or tissue. Another disease linked to this disorder is Diabeteswhich can cause similar effects concentrated in the kidneys. From autopsies. In his study, the team responsible for the analysis had 1,781 participantsalready killed ages above 75 years. To study the impact of alcohol in their brains, cases in which brain autopsies of the bodies were used. Thus the equipment was able to look for signs of brain injuries such as TAU protein accumulations and signs of hyaline arterosclerosis. How much is a lot. The question of How much alcohol is a lot of alcohol It is difficult to answer clearly and concisely. The tolerance of our body with respect to this substance depends on factors such as our age, sex or body mass. In his study, the team conducted interviews with the relatives of the deceased people on which the study was based. From the information they classified these people among those who never drank (965 people in this group); moderate drinkers (319 participants); excess drinkers (129 people); and ex -owners who did it in excess (368 people). Finding the relationship. Once other factors were controlled, the team estimated that people in the category of excessive consumption had a risk of cerebral vascular lesions 133% higher than those who did not drink.

How Spain is putting aside to your favorite measure to drink beer

by

We Spaniards like to practice Terraceo with friendsa skewer and a good beer, but that It does not mean That we do it the same throughout Spain. Not even what The beer jargon be the same throughout the country. Especially if we talk about tap beer. Moreover, if you move frequently from north to south it is likely that you have found that not all waiters seem to use the same terms or even how the same word can mean different things, understanding by “different” the milliliters that you will find in the glass. In case that “Babel Torre” was not enough, now (at least In part of Spain) There is an upward option: the cup, something that tells us about beer but also how we drink it and formats beyond the star measure, cane. Spain, beer land. We Spaniards like beer. And that statement has few laps because it relies on contributing data and sounds collected by the sector itself. In 2023 its consumption stood around 43 million of hectoliters, with an average intake of 55 l per person. In fact (and although demand It has ups and downs) Its consumption has been winning weight In front of the wine, also linked to the Spanish table. That we like to take a good lager or IPA does not mean that everywhere you drink (and ask for) the same. Map prepared by brewers of Spain. How do you drink in Spain? That same question was asked a few years ago Brewers from Spainthe association that groups the great producers of the country, after verifying that although a beer is a beer anywhere in Spain, the thing changes when we talk about how to serve it. “Depending on the format we want and the area, an act as simple and everyday as asking for a beer, if it is not done correctly, it can become a real challenge,” Recognize. Where is a good map … To clear doubts, Cervecer did two things: he created A glossary and a map that helps appreciate how beers usually drink) throughout the country. The graph should be handled however with some caution. For example, the association recalls that although in Salamanca or Valladolid, tap beer is usually used in vessels between 100 and 140 ml called “short”, in Galicia that same word refers to “the lifetime cane”, a major format. If you are in the Basque Country, you better call it “Zurito.” Or “penalty” in Aragon. And that’s all? No. The cane is the “par excellence” format and that word understands it in virtually all the businesses of Spain, but manufacturers warn: “While in areas such as Madrid the glass measure is 200 ml, in other places the size is superior. Thus, if a Basque wants to take the 350 of a Basque cane in Madrid will have to ask for a double, the most similar measure.” Since the cane usually moves around 200 ml, the normal thing would be that the double was 400 ml, but that logic has nuances again. In Basque Country if we want that amount of beer drink, it advises to use another term: “Canyon.” The wide brewing glossary is completed with words such as “Botellín”, “fifth” or “third”, which are the terms used for bottles depending on whether you want the fifth part or a third of liter. The thing is complicated, however, with exceptions: Asturias, Cantabria or Catalonia use terms as “average” or “median.” If you are looking for you will even find guides who speak of 25 either 30 forms To ask for beer, including “pots”, “botijos”, “tank” or “xibeca”. Complicated? There are more. In case the “photography” was not complex enough, at least in part of Spain it is being added An extra factor: The form. That is, the key is no longer how much or how we drink beer, but what we drink it. That is: glass or glass. The nuance is interesting and slid yesterday The voice of Galicia in An article in which he explains how in Santiago de Compostela it is increasingly common to see people with beers in the glass instead of a glass. The question is evident: “Why do the reeds serve as if they were a wine?” After talking with compostela hoteliers, the newspaper Slide Some practical explanations: the glasses are easier to store (they can be hung upside down) and there are those who defend that they help preserve the organoleptic properties of beer. In fact there are places that San Cups designed for the Lager. “Optimal formats”. “The crystal is quite broken and you have to replace, but it is the best form”, They argue From a compostelano store. Galicia star itself claims That each beer has “its cup” and details the differences of form and use between the flute (15-40 CL), the Pilsner vessel (15-40), the tulip (20-50), Weizen (30-50), Snifter (30-50), chalice (30-50) or the teku, used in tastings and between 33 and 50 cl. “If we leave aside its aesthetic or historical component, it cannot be denied that some formats are optimal for certain styles,” The company points out. Cup question … And something else. In the passage of the vessels to the glasses there is, however, another factor that speaks, rather than the bars or beer itself, how we enjoy it. One of Santiago’s hoteliers in fact explains that there are clients who ask them to serve the cane in a glass of wine, either because the glass is finer or for quantity. “The wine brings between 44 and 52 CL and the cane is 33,” clarifies the hotelier, who denies that the cane has less amount than a bottle. The slow decline of the cane. The phenomenon also coincides with an apparent decay of the cane and other reduced formats in favor of others of larger. Two years ago Straight to the palate I pointed Already as many bars in Madrid (and other points in Spain) were going from the standard … Read more
