China is telling us what a future full of electric cars looks like. And we already know which are the most reliable brands

by

The conquest of China in the automobile industry global has made us increasingly pay attention to the country’s manufacturers and the models that are coming out every year. China leads in new energy vehiclesalthough the reliability of their cars has always been questioned. The latest report Quality test launched by the analysis firm LandRoads offers us a very interesting perspective, as it studies the models that have initially caused the least problems since their purchase. In this aspect, the ranking places the Xiaomi SU7 as the most reliable large sedan, while the Tesla Model 3 dominates among the midsize models. Below these lines we tell you all the details. What is the ranking about?. LandRoads has published its annual report on quality in electric and plug-in hybrid vehicles in the Chinese market, analyzing 6,950 incidents reported by users. According to the report, 3,687 were quality problems and 3,263 were design-related. In the overall ranking by brand, AITO tops the list with a quality risk index of 123 points, followed by Mercedes-Benz (126) and Tesla (146). Image: ChinaEVHome. Source: LandRoads Why does it matter? The Chinese electric vehicle market is immersed in a frenetic race to incorporate more technology and functions. However, the study gives us clues that not all manufacturers are facing this battle completely well. The three main problems reported were noise (24.6% of complaints), exterior components (18%) and failures in intelligent systems (17.3%). Together they represent more than 60% of incidents, pointing out the critical points where the industry needs to improve. Categories. Highlights of the report indicate that: In medium-large sedans and above, the Xiaomi SU7 wins with an index of 108 points, well ahead of the Stelato S9 (218) and the IM L6 (237), according to LandRoads data. In midsize and compact sedans, the Tesla Model 3 leads with 104 points, followed by the Nio Firefly, BMW i3, Geely Galaxy Xingyuan and BYD Seal 06 GT. Among large SUVs, the top three spots go to AITO models: the M9 (88 points), M8 (98) and M7 (135), with the Li Auto L8 and Voyah FREE completing the top five. In medium and compact SUVs, the Avatr 07 stands out (92 points), ahead of the BYD Sealion 05 EV, Yuan UP, Tesla Model Y and Yuan Plus. In MPVs, the Voyah Dreamer records the best result with 192 points. Balance. The report also points out a phenomenon he calls a “high-equipment, high-risk concentration zone.” And according to LandRoads, as some manufacturers rapidly accumulate new features, the maturity and stability of the systems does not advance at the same pace, amplifying the risk of vehicle quality. According to the study, AITO, Xiaomi, NIO, Zeekr, Li Auto and Voyah have managed to maintain low risk rates despite offering high levels of equipment. More mature electronic architectures, better coordination with suppliers and exhaustive validation systems in all types of scenarios come into play here. Looking long term. LandRoads concludes in its study that the electric vehicle industry is moving from simply adding features and functions to the integration capacity and long-term stability of all these novel systems. Furthermore, seeing Aito above manufacturers like Mercedes or Tesla gives us clues about the transition we are experiencing and the ability of Chinese manufacturers to produce a product that lives up to it.

We have been telling ourselves since 1945 that we should drink “two liters of water a day.” Science is clear that this is not the case.

by

One of the most popular rules in popular health culturewithout a doubt it is in the amount of water you have to drink per day. An amount that is located in eight glasses a day or what is the same: the immovable figure of two literss. We see it in fitness applications, in influencers’ advice and we hear it repeated like a mantra, but the reality is that there is quite a myth behind this. We are different people. A very common phrase within medicine is precisely “there are no equal people”, and not only because of the external physique, but because of everything that is inside. This forces the medicine Focus towards a more individualized idea in your medical advice that have to be given, included in nutrition or water consumption. This forces us to have to personalize the amount of water that each person should consume, because a person who is 2 meters tall and weighs 100 kg with a large amount of muscle is not the same as an elderly person who has a much slower metabolism. Logically, the two liters of water mantra cannot be established here. The origin of the error. To understand why we drink (or think we should drink) so much, you have to travel back to 1945. According to key review by Dr. Heinz Valtin in it American Journal of Physiology 2002, the myth of the “8×8” rule, that is, 8 8-ounce glasses to have almost 2 liters of water, probably comes from a misinterpretation of a guide from the Food and Nutrition Board. A guide that indicated that it was always recommended to have an adequate intake of 2.5 liters of fluids per day. But most people ignored the accompanying sentence that said, “most of this amount is in prepared foods.” What the institutions say. So the question is quite clear: how much should we drink per day? In this case there are different official figures, but they have fine print. We have one of the examples in the European Food Safety Authority Panel 2010 established adequate water intake at 2 liters per day for women and 2.5 liters per day for men. But here’s the key: the EFSA specifies that this refers to total water, that is, the sum of drinks plus food. And there are many dishes that have a large amount of water, such as soup, although fruits also have a lot of water inside. Even in the United States. If we move to the recommendations made in the Institute of Medicine (IOM) of the USA from 2005, suggests that the total water figures should be 2.7 liters per day for women and 3.7 liters per day for men. But again, it includes all the dietary intake that is made per day and not just glasses of tap water. The latest science. If we come more to the present, we also have scientific studies that have sought to dismantle a universal fixed figure set at two liters per day. One of the most important is the one published in Science in 2022 that used isotopes to measure water exchange in 5,604 people, and that showed that real needs vary enormously between people. One of the conclusions they addressed was that for most people in temperate climates and with sedentary lives, the real water intake needs are between 1.5 and 1.8 liters per day, far from the demands of wellness marketing. And it is reinforced. It is not a study that is isolated, but also in 2022 the magazine Scientific Reports, published research where this idea was reinforced: they predict necessary beverage intakes of about 1.6 L for women and 2.0 L for men, always depending on factors such as age, sex and body composition. Is more water better? One of the most repeated arguments by proponents of hyperhydration is that we should drink “before we are thirsty.” modern physiology, backed by scientific reviews and analysis of urinary osmolarity, refutes this fear that we may have. Specifically, the human body has an extremely sensitive osmoregulation system. When the concentration of solutes in the blood increases by only 2%well below clinical dehydration, the brain already activates the sensation of being thirsty and releases the necessary hormone to begin conserving water so that it does not ‘leave’ in the urine. There are exceptions. Unless you are an elderly person (whose thirst sensation is attenuated) or a high-performance athlete in the midst of intense effort, drinking when thirsty is the most accurate and scientifically validated strategy for maintaining water balance. When you should drink more water. That the “mandatory two liters” are a myth does not mean that water is not logically vital. The most recent systematic reviews and other clinical means confirm that increasing water intake has clear therapeutic benefits in very specific cases that are not universal. These can be the following: Having a kidney stone: here the “more, the better” applies since increasing urinary flow is key to preventing the recurrence of this disease. Urinary infections: a problem that mainly affects women, and that requires ‘overhydration’ to reduce risk of new episodes. Weight loss: Although the evidence is mixed, drinking water may help with satiety and, marginally, energy expenditure. Although it is not a magic solution against obesity. More common sense. The obsession with two liters is a perfect example of how an old and misinterpreted scientific recommendation becomes a cultural dogma. The reality, supported by decades of studies from Valtin to the latest isotopic analyses, is that we are not machines that need a fixed tank filling every 24 hours. In this way, our body’s water needs are dynamic. Water needs are dynamic. If you eat a lot of fruits and vegetables, work in an air-conditioned office, and don’t run marathons every day, forcing yourself to drink 2 liters of extra water will probably only do one thing: interrupting your work to go to the bathroom more times. The situation. In this way we can understand that … Read more

We have been telling ourselves for decades that we have the Internet thanks to military research. The problem is that it is false

by

It is difficult to imagine that something as impressive as the Internet could be summarized just over 40 years ago in a single page. The map of germ of the internet, ARPANETtook up no more than a DIN A4 sheet of paper and reflected the less than 50 computers that at the beginning of the Internet were connected to each other. But even more curious is the story of how ARPANET was born, which may not be as you have been told. It all happened almost midnight on October 29, 1969, in a small room at the University of California (UCLA), and with a message that only said “it“. The true origin Search the Internet about its history (from the Internet itself), and you will find that the most common thing is to talk about its military origin. Technically it is correct since ARPANET was developed by the ARPA (Advanced Research Projects Agency), an institution that depended on the US Department of Defense. But the reasons were not military even though One of the minds behind some of the ideas that helped create ARPANET, Paul Baran, worked precisely with the motivation that cold war between the US and the USSR would not end with a blockade and destruction of the communications and control structures of the US army in the event of a nuclear attack. You will indeed find many references to this idea, which results in a story that makes for an entertaining movie. hollywood but in reality it was not exactly with that motivation that ARPANET was born. In the 1960s, within ARPA there was the Information Processing Techniques Office (IPTO), at that time focused on taking full advantage of computers within the administration. Robert Taylor, one of the fathers of the Internet, began his career as director of the IPTO in 1966, and proposed to the then director of ARPA the possibility of connecting computers together to optimize their use. With this structure of networked computers (an idea that he took from the previous works of JCR Lickliderpioneer in 1962 by proposing the possibility of interconnecting equipment with each other) the ARPA could better manage your budget for computers and not distribute efforts uselessly but concentrate them on a few but very powerful computers connected to each other which would allow resources and results to be shared between researchers and centers. “lo”, first message between computers on the network Taylor was not limited to the resource of sharing computers and results between centers as an advantage of his ARPANET. If the idea worked, the agency was ensuring that it could use more computer models of different types without the compatibility or use of terminals to access them being a nightmare, while at the same time allowing the creation of protection against failures, so that with the non-centralized network structure proposed, if one computer failed, the others could continue working. Taylor’s initial proposal consisted of a test network with four nodes that they could expand if the results proved them right. ARPANET was born. The Internet was on the way. If you are passing through California, a recommended visit is in room 3420 Boelter Hall at the University (UCLA). Do not look for it as such because after being forgotten and until its use as a common room, it was recently restored and became part of the Kleinrock Center for Internet Studies (KCIS). Much of the history and documents are concentrated there (there is no waste of original presentation of ARPANET) and equipment that allowed the first node to be established between computers. But it’s actually a fantastic tribute to Leonard Kleinrocka professor who in 1969, right from that small room at the university, sent the first message on ARPANET. It was 10:30 at night on October 29, 1969 when, from the SDS Sigma 7 computer in said room, Professor Kleinrock sent the LOGIN message to the SDS 940 computer at the Stanford Research Institute, the computer with which he was connected in a basic way. The message remained a curious “lo” since there was a transmission failureand it was not until an hour later that the initial transmission could be completed. The first connection had occurred between the first two computers within the ARPANET. Two weeks later there were 4 interconnected teams, and in two years, almost seventy. And no one could stop this revolution. In Xataka | In 1995 ‘Toy Story’ forever changed the way animated films are made.

We’ve been telling ourselves for 100 years that breakfast is the “most important meal of the day.” The problem is that it is not true

by

They’ve been hammering us with that slogan for so long that it should be true. That is, if from different speakers they proclaim that under no circumstances should we skip breakfast, it will be because it is lunch. most important of the day. But how we already pointed herethe studies on which they have relied to affirm this are conclusive. It also does not seem true that it is good to have breakfast to “start the day with energy”, nor that it reduces our appetite throughout the day. So who and why started proclaiming it? The history of breakfast is like many other social uses, something that has more to do with the roots of the context from which it came than with an innate need of our body to practice it. Several things came together between the 19th and 20th centuries so that breakfast became established as just another meal in Western societies. The first, the change of production model. Before, workers, mostly rural and dedicated to work in the fields, ate breakfast quickly whatever was out therelike last night’s leftovers. It wasn’t so much a meal as it was an appetizer. With the arrival of cities and the industrial revolution, work schedules were established. The workers, who spent the entire day working, saw the benefit of eating something before going to work. From 1822 onwards And here things started to get interesting. Progressively, the more money American workers were able to earn, they ate more meat. It was the star product to eat in the morning. They could prepare a meatloaf, a chicken or beef dish in the same way they would at lunch or dinner time. And all of this cooked with butter. The dyspepsia or indigestion became a public health problem on the level that obesity is now. The people of North America ate poorly, foods that were too heavy and altered their intestinal flow. People who needed to eat very well to go to work. The 19th century was also the time when western doctors They began to worry about nutritional health, germs and, later, vitamins. Thus, while the newspapers and magazines harshly criticized the problems caused by dyspepsiathe industry and the market naturally looked for a substitute. There came muesli and cereals, then minimally processed flour or corn that in many cases had to be soaked before consumption. The initial flavor and appearance of the cereals was that of military porridgebut they were attractive to a large part of the consumers: it seemed like a “health” productnot like those red meats that prevented good circulation. Furthermore, it was a food that I didn’t need to be preparedas easy as putting them together with a little milk so you can swallow them and go to work. Replacing big meals in the morning with a light product The health of the population improved, which is why many doctors and cereal merchants used this slogan to expand their consumption: breakfast is the most important meal of the dayand that is why you should take care of yourself early in the morning. Is practically the same idea of ​​health that whole grain houses continue to sell us so that we can lose weight. Corn flakes arrive Breakfast then began to be seen as the solution to all the problems. For the little ones, without a good breakfast they would not be able to reach their maximum level of effort at school. Also alcoholism It was caused by lack of food in the morning. According to certain prestigious doctors of the period, morning hunger encouraged the employee to begin to abuse the bottle until he became dependent on it. Some vendors went even further and talked about how their cereals They could cure malaria and appendicitis. Already then the cereal was promoted as “organic” foodAs we see today, some products are sold more expensive and not necessarily with better nutritional results. But the beneficial halo of the cereal remained and extended to the breakfast ritual, whether it was processed wheat, fruits or other foods. breakfast had come to stay. From the 19th and 20th centuries we move to the 21st century, when the saying, never sufficiently proven by science, has already been established as an immovable truth. Cereals have long been no longer tasteless porridge but small ones processed sugar balls in boxes with smiling animals that bill billions of dollars a year. And there is another agent that, for years, has been interested in making sure you remember that “breakfast is the most important meal of the day” and, therefore, eat quite well: fast food chains. Some essays have pointed out how the marketing of companies like McDonalds or Starbucks is being much more aggressive in morning products such as McMuffins or cheesecakes than in foods at lunch or dinner time. According to them, the new big dispute is here. While many workers have already decided on their meal locations, there is an increase in people who is going to breakfast at chains outside the house. And how mornings are the time for routinehumans tend to choose one place or another to have our breakfast and not leave the pattern except in case of emergency. If McDonalds gets you to go to their establishment in the morning, in a way you are marrying them gastronomically. And, well, you know, it’s the first meal, so it’s okay if it’s a little excessive, you’ll burn it off throughout the day (this, as we already explained, it is not completely contrasted). Thus, from a creditable beginning in which citizens’ nutrition was improved, we have moved to a point where the industry has been adapting to our tastes and modifying our diet to the point of harming us all. Although, if we think about it, the phrase is still as true now as it was 300 years ago: “breakfast is the most important meal of the day.” It is the most important. And the most discussed.
