While the world desperately seeks rare earth, China has an overwhelming advantage: it’s called Wem

by

It seems clear that it has begun A race On the planet: the search for Rare earths and the essential critical minerals for many of the sectors that mark the geopolitical agenda. The problem for 99.9% of nations is the same: when they seem to have reached a deposit there are already A Chinese flag. What is not usually explained so much is how Beijing does. The miliar origin. Deep in the mountains of center of China extends A monumental installation that transforms both the landscape and the global competition for strategic resources. It is a gigantic antenna of 500 kilowatts, with lines that are deployed over 80 and 120 kilometers, originally conceived to maintain communication with underwater underwater. This electromagnetic colossus, whose extension exceeds in five times the New York surfacehas been converted into a decisive instrument for the exploration of critical minerals, projecting signals capable of penetrating kilometers in the earth’s crust and revealing deposits that previously remained out of human reach. What began as a military project has become a Scientific and Technological Weapon which gives Beijing a remarkable advantage in the race for the resources that will define the future of energy and industry. Electromagnetic exploration. A study of the China Geological Survey (CGS), published in the Geophysical & Geochemical Exploration magazine, has detailed how the country has managed to monopolize Electromagnetic systems of ultra-high power. All platforms that exceed 100 kW are in Chinese territory, while the most powerful tool in the United States barely reaches 30 kW. The difference is not trivial: this technological leap has allowed Chinese geologists to discover in recent years sites of historical magnitude, such as the Greater gold deposit of the world, reserves Lithium ultra-extends and uranium veins in depths Never achieved. The research led by Chen Hui and his team affirms That these innovations consolidate China’s world position in electromagnetic exploration theory and technology, placing it far ahead of any western competitor. The challenge. As the superficial deposits of copper, lithium, cobalt and rare earths are exhausted, the exploration has moved to what geologists call The “Second Mineral Space”: An underground strip that extends between 500 and 2,000 meters deep. In this environment, the signs issued by mineral bodies are extremely weak and are usually buried under the cultural noise generated by electricity lines, urban infrastructure and extractive operations. The Chinese response has been to redefine the scale of prospecting: multiply the transmission power by above 100 kWflooding the subsoil with signs capable of crossing interference and reaching depths of up to 3,000 meters with unprecedented clarity. Advances in the subsoil cartography. The jump is not limited to power. While conventional techniques relied on two -dimensional models not suitable for complex structures, Chinese systems use Sensors distributed networks and multidirectional field sources that allow a real three -dimensional image of the subsoil. In the Jiama copper mine, in the Tibet, a controlled audio-magnetothelúrica tensorial study (CSAMT) reached unpublished resolutions at more than 3,000 meters, subsequently confirmed with drilling nuclei. These results They far exceeded to the Magnetotheluric of Natural Source, usually ineffective in saturated noise environments. The methods. One of the most prominent advances is the Electromagnetic method wide field, developed by Professor He Jishan, which allows you to obtain reliable data even in the so -called “nearby field zone”, where the records were not very useful. At the same time, the time-frequency electromagnetic systems are expanding the available information by measuring not only the resistance of the materials, but also its polarization and permeabilityessential parameters to distinguish between different types of deposits. The Wem project. And so we reach the clearest symbol of this ambition: The Wem project (Wireless Electromagnetic Method), whose colossal structure crosses China’s heart with two antenna lines arranged almost at right angles. This system, which began as a naval communication tool, has become the First electromagnetic transmitter of continental scale used in the prospecting of resources. In a national test carried out in 2023its signs were detected from Tibet to Interior Mongolia and Guangdong, more than 2,000 kilometers away. In the area of ​​Xiong’an there were magnetic fields up to seven times higher than the natural background noise, an unequivocal demonstration of the system’s capacity to impose itself on the most complex interference. Strategic advantage. In other words, with these Beijing technologies It is placed at the head of the struggle for the essential mineral resources for the energy transition and the green technologies: lithium for batteries, cobalt for high resistance alloys and rare earths essential in modern electronics. In contrast, most Western countries lack comparable systems and, except Russia, almost none use ultra-high power instruments in terrestrial prospecting. Even the most powerful teams manufactured in the West have been designed at China, which underlines the existing technological dependence. A new geopolitical board. China’s ability to identify deep deposits quickly Not only is it a scientific advantage, but also strategic. Control over technology and data places Beijing in a position to mark the rhythm of the discovery of resources in the coming decades. If you want, in a context where the energy transition redefines the global value chains, who controls access to lithium, cobalt and rare earth will control much of the industrial future. With the deployment of Giant antennas and electromagnetic systems Of unpublished power, China is making it clear that it does not intend to participate in the race: its goal is to win it.

Its technology is that of the botijo

by

Three of the ten hottest days of the last 75 years in Spain We suffer this summer. August was Extremely warm and The Mediterranean is a “pressure pot”. These conditions They involve greater use of air conditioningbut it is not a restricted phenomenon to Spain: the number of heat days also increases in other countries. Urgent changes in the materials with which we buildand a couple of Swedish designers have taken a brick capable of lowering the temperature around them. It is called Bloc, and the best of all is that it uses the same technology as a botijo. 3D printed terracotta. Luc Schweizer and Andrin Stocker are members of the Higher School of the Arts of Zurich –ZHDK– They had an idea: convert certain points of the cities into “cold” places. Do in public space is complex because depending on the air-conditioning It is not a very viable option, and trees cannot do all the work either. They occurred to them something better: combine in a terracotta brick both a wind tunnel and a water tank. The promise is that the temperature of the space can lower around it by about nine degrees, and the most amazing thing is that it can achieve it with a combination of solar energy and Evaporation cooling. Botijo ​​technology. All this botijo ​​looks like a joke, But it is not. This clay gadget It has a very simple operation To keep the water fresh inside: it is filtered through the pores of the walls of the botijo ​​and, by contrast to the exterior, evaporates. Evaporate water takes part in the thermal energy of water, so the remaining liquid is maintained at a fresher temperature. As They affirm Those responsible, “is a low technology modular cooling system that uses evaporation cooling to reduce air temperature.” The operation is identical to that of the botijo, thanks to the fact that porous ceramic bricks absorb the water and it evaporates abroad, but with a nuance: they have added a fan. This fan drives the air through the wind tunnel that form the bricks and the cooler air goes abroad, cooling the most immediate space to the structure. To make it more sustainable, structures have Solar panels which are the ones that feed the fan. Modular. Within each brick there is a small water tank, which the equipment estimates that it would have to be filled with both rainwater collection naturally by the ‘device’ design and with water from municipal services. It would be the largest stumbling block, because otherwise, they claim that it is totally modular and the structures can grow freely both in height and in width. Apart from A kind of umbrellas With banks around them, they can be used to create refrigerated marques or cooler bus stops. Next steps. Before launching the bells on the fly, as is usually the case in these cases, it is a mere project. Both are already creating a 1: 1 scale prototype to test it in a real urban environment and evaluate long -term performance, but see applications like this in the streets around the world will not be immediate. They also comment that, apart from their outdoor use, other applications can be explored, such as integrate them into the facade of a building to cool large interior spaces such as exhibition rooms. Is not so unique. As a curiosity, in India they are already testing something very similar: clay flutes with this same technology They are able to lower the temperature of exterior and interior spaces between six and fifteen degrees, but that have the same problem: or have water … or do not work. Bloc, specifically, needs about 50 liters of water in hot days. Apart from whether or not these innovations end up applying, it is interesting to see How millenary technology is the touchstone for current problems. And how we keep looking again and again at the materials and to the bricks of the past. Images | ZHDK In Xataka | We have centuries using terracotta bricks.

The “best mechanic in Spain” says that Low Cost gasoline is of worse quality than the premium. Reality is much more complex

by

In the long term, fuel Low Cost “It can cause breakdowns.” We do not say it, says Carlos Pérez, recognized as “best mechanic in Spain” in an interview with Canal Moveo de The avant -garde. And we don’t give it because, simply, there is no reasons to say it. In fact, Carlos Pérez himself emphasizes that “all gasoline ultimately come from the same wholesale suppliers.” So what happens? Who. As we say, one of the spaces that The avant -garde He dedicates to the mobility sector has interviewed Carlos Pérez, known on the Internet as “the best mechanic in Spain.” The title is no invention, among the different awards he has obtained we find the one delivered by The workshop community who are focused on communication within the post -sales market. Since then, Pérez has granted various interviews to different media in which he has been explained about What are the most reliable brandswhat are they the car models that recommend Or, simply, which is the best gasoline to use. Yes, but. And here comes the controversy. In his statements about gasoline to use, Carlos Pérez assured the following to The avant -garde: “Although all gasoline ultimately come from the same wholesale suppliers, the differences are in the additives that each company incorporates. These additives are those that help to keep the feeding system clean and prevent the accumulation of waste in the engine, which can affect the performance and durability of the vehicle. The price can be tempting, but in the long term, the use of fuel That supposes in repairs “ That is, a Yes, but in full rule. According to Pérez, there should be no reason to distrust the cheapest fuels but in the long run “it can cause breakdowns and greater engine wear.” Obviously, the price would not compensate for the expense and headaches of the breakdowns. Same origin. The truth is that in Spain there should be no differences between refuel Low Cost or supposed fuel Premium. Because deep down, the fuel is exactly the same. And this is not much less. In Xataka We already played this topic in 2015. Then we explained that the origin of both fuels is the same: CLH or hydrocarbon logistics company that In 2021 he changed his name to exolum. This receives the fuel from the refineries that are distributed by Spain in the hands of BP, Cepsa Moeve or repsol. This fuel already arrives with quality standards that guarantee a good product. This fuel is maintained in the exolum facilities until it is distributed by the service stations. It is here where the difference between products occurs: additives yes or additives no. The additives. To begin with, the exolum itself already has His own additives (HQ300) For part of the fuel it stores. It is the responsibility of the Marketing in charge of fuel with additives or without them. Obviously, this second is cheaper. What is an additive thinking? In theoryto improve long -term engine and vehicle care. Companies Premium Do you sell that their formulas manage to leave less remains in the engines or allow more kilometers with the same amount of fuel. And is there scientific evidence? Really, none. At least that is what Carles Fité, Professor of Chemical Engineering, and Rodrigo Soto, chemical engineering reader, who asked about this same matter, pointed out that “all are equal. I see no difference at this level of analysis.” According to their samples, “they basically contain the same compounds and in the same proportions. Everything comes out very very the same”, in words collected by The confidential. Nor have they found substantial differences in the OCU. In fact, they point out that we are talking more about blind confidence in the effects of additives than on realistic checks: “The effects of additives on engines and gasoline consumption do not seem very verifiable. (…) Prove that an additive lengthens engine life is very difficult, because there is no way to determine how much that same engine would have lasted if that gasoline had not used.” And the secret? The secret is called the economy of scale. Simply, there are two types of business when we talk about service stations. The gas stations Low Cost They can save the customer money because they themselves They already save money on operational costs Of their businesses: they do not usually have employees, they do not invest in R&D to improve those fuels and do not invest in advertising, trusting in the mouth-oreja. On the contrary, gasoline stations Premium They base their business on those additives that generate confidence in the client. But also In formulas to catch you in the following purchase such as loyalty cards or stores that orbit around the suppliers. Also in their Agreements with other companies as insurance companies or large supermarkets. Scams and maintenance. In summary, the quality of the repossed product has much more to do with the maintenance of the service station (which is renewed regularly and does not spend too much time in deposits, for example) and, above all, with complying with the minimum quality standards. The latter should be an endorsement when we repost in Spanish gas stations, however, in recent months the SERVICE STATION SHOWS They have used worse quality fuel and took advantage of great sales at very low prices to subsequently scam the State in the presentation of the VAT tax. This has generated a worse image to the product Low Cost. Photo | BALLENOIL AND BP In Xataka | Diesel or gasoline: what are the differences and which one is better to buy according to your use

Ryanair has put the Spanish province airports in check. Fortunately for them, there is a thing called “capitalism”

by

Spanish airports are living a tremendous snake in recent months, and the absolute protagonist is Ryanair. The Irish airline has been using smaller airports for months, such as negotiating weapon in battle against airport ratesthreatening to leave them lying if their conditions were not met. Threatened … and fulfilled, being Valladolid’s one of the most affected airports. But there Where Ryanair closedother companies have seen a chance. And, as the Minister of Transportation says: “To dead king, king on.” What’s happening. AENA is the public company that is responsible for the management of airports in Spain. A few months ago he announced that, as of March 2026, it would increase airport rates by 6.5%. This implies that the maximum entrance per traveler will go from 10.35 euros to 11.03 euros, a rise of 68 cents. The reaction Ryanair was … sound, so to speak. Through several very public profiles, including that of its controversial CEO, Michael O’LearyThe company described the increase as unjustified, stating that regional airports would be less competitive against other European destinations. In general, the defense of Ryanair is based on affirming that Aena acts as a monopoly when the benefits of travelers and regional connectivity are put. Affected. The manager justifies the climb to the need to face a Investment Plan of about 13,000 million euros with the aim of modernizing the network in the coming years before an expected increase in demand. All this led to the president of AENA and the Ministry of Transportation accused Ryanair of being blackmailing the country. Also accuses To the company to use that increase in rates as an excuse to stop operating in regional airports, moving to the “airports in which they can set higher prices in their tickets to earn more money”. In fact, a pulse can be allowed like this. Ryanair’s response? Trim a Million places Facing the Christmas campaign of this 2025 through the cessation of operations in those regional airports in which the airline was the main mode of connection with other airports. The most affectedin addition to Valladolid, Son Vigo or Santiago de Compostela, but also Tenerife Norte, Asturias, Santander, Zaragoza, Jerez or Vitoria. airport Capacity cuts for winter 2025 & 2026 Santiago Base closure (two less aircraft, 80% less capacity) sherry Closing Valladolid Closing Tenerife Norte Closing Vigo Closing Santander -38% Saragossa Closing Asturias -16% Vitoria -2% Canary Islands -10% Dead king, king. The truth is that Ryanair is one of the most powerful companies at European level, especially in these smaller airports, since its model is the one that allows connections between cities that other companies do not cover. However, his withdrawal of some Spanish airports is not something that worries one of the protagonists of this story: the Minister of Transport and Sustainable Mobility. Óscar Puente defended A few days ago, Ryanair’s march would be compensated with the arrival of other companies. The minister argued that “no company will condition airport policy with threats, underlining That “to dead king, king placed”, and it seems that those new ‘kings’ are already appearing their heads. To attack. It was the bridge itself who announced that airlines as Vueling would “immediately” cover the routes abandoned by Ryanair for this winter, ensuring that he has worked in negotiations with both vs. with other companies to fill that void left by the Irish company. Vueling will reinforce its presence in Santiago and Tenerife Norte, but it is not the only company that has seen an opportunity in this situation. Iberia Express or Wizz Air They also work to cover part of the routes operated by Ryanair. Specifically, from Independent comment which turning will increase its capacity by 15% in Santiago (reaching 578,000 seats) and 11% in Tenerife Norte (900,000 seats). Wizz Air, meanwhile, will open 40 additional routes until March 2026. Another of those who I could enter the game It is volotea, an airline that is focused on connecting small and medium cities that has already collected the Guante of Ryanair’s abandonment of French airports. Because this struggle of Ryanair against rates are also having it in parallel in France. And the train? Of course, Ryanair has put the increase in rates in the center of the debate, but there is something that has been forged in recent years: the expansion of high speed. A few weeks ago we already commented that that of Santiago and Vigo, airports in which the Irish has closed operations, are two cities to which The arrival of high speed is especially affecting. In Asturias There are still complicationsbut new sections are planned that will allow the train to fight the plane soon. And in Zaragoza not only Renfe operates: Ouigo and Iro They joined not so much. Now, where the train is not an option is in the Canary Islands, where Ryanair will reduce 400,000 places in winter, canceling 36 connections. There will be companies such as Vueling, Iberia Express or Binter who will have to demonstrate whether they can operate without travelers missing Ryanair. This next winter will be the fire test. In the end, Ryanair has been able to blackmail Aena (and other European organizations) to some extent, since if he leaves his routes, due to competition, there are other companies that are looking forward to occupying their place.

stop desertification in China

by

China has found an ingenious way to give a second life to the giants who once dominated their energy landscape. The pales of the wind turbines, who begin to retire after 20 or 25 years of service, are becoming more than a difficult product to recycle: they now serve to stop an enemy that advances silently, desertification. A barrier against the sand. Researchers at Research Station of Gobi Desert Ecology and Environment, Under the Chinese Academy of SciencesThey have found a way to transform the old blades of wind turbines into porous barriers against the sand. It is a solution that takes advantage of the geographical coincidence: many of the wind farms of western China are installed in arid or semi -desert regions, just where the control of the desert progress is most lacking. A quite simple process. The turbines are cut, pierce and process until they are made into porous structures. The wind can cross them, but in a controlled way: enough to catch the sand and alter its flow. In laboratory tests They showed that these barriers They are 14 times more resistant than composite wooden boards and that support ultraviolet radiation, extreme heat and constant abrasion of the sand. After that, the experiments in wind tunnels and computer simulations They confirmed that they reduce Significantly the transport of sand at ground level. Unlike traditional methods – like straw or cane barriers, which decompose quickly – new structures are designed to resist for years in extreme conditions. A double benefit. The value of this innovation goes far beyond engineering. The new barriers offer entire communities a more stable protection in front of sand storms that destroy oasis and crops. The clearest example is Dunhuang, in the province of Gansu, which located on the edge of the Kumtag desert, just 4.5% of its surface is covered by Oasis, and its famous cultural treasures – like Mogao’s caves— They have been threatened by the sand for decades. For its part, the project responds to a more urgent need: the massive recycling of wind blades. According to China Dailyduring the 14th five-year plan (2021-2025) is expected to withdraw more than 1.2 million kilowatts of wind capacity and in the following plan (2026-2030), the figure could reach 10 million kW per year. This volume of waste poses an environmental problem, but also an opportunity to transform them into useful resources there where they occur. Looking for solutions before the residue. The challenge now is to climb the technology. Field trials They continue to adapt it To different climates and deserts, and the potential is enormous: convert an awkward residue into a key environmental management tool. China, that already leads the world renewable capacityshows with projects like this how its strategy goes beyond installing panels and mills: it is about closing the circle, taking advantage of waste and, incidentally, protecting fragile territories against desertification. The energy transition not only produces electricity: it can also rewrite the landscape. Image | Pexels Xataka | He was deported to China after co -founding NASA’s JPL.

When in 1907 a doctor tried to demonstrate the existence of the soul using a scale

by

When We are going to bedthe brain Beast begins to work. It is when we review the day, We can think of great ideas that we do not point and ask ourselves questions of all kinds that We do not usually remember the next morning. Duncan Macdougall did remember what may be asked just before sleeping: How much does the human soul weigh? The concept of soul It is complicated, since there are those who see it as an intrinsic element to the body, but also something that fades “when we die. Macdougall, a doctor from Haverhill, Massachusetts, had to say “science is not done alone” and got to work to test a hypothesis. What hypothesis? That, if the soul exists and is inside the body, it must have a weight. His theory was that, if at the time of death the soul escapes our body, it could measure its weight. And he got to the work of the most handmade work possible. Also of the least scientific. Science is not done alone, you have to do it He is romantic, almost tender, now think about his reasoning. But he had all the logic of the world to respond to something so complex: at the time of death, there should be a detectable loss of weight because the soul abandons the body. As if the soul were the “pilot” who jumps from the plane before crashing. To test his theory, Macdougall built a fairly special scale: a bed mounted on a weight capable of detecting differences of up to five grams. His plan was not very ethical, but all for the sake of science and to try something so important: place dying patients on top of the scale and monitor weight changes just before and after death. It took his thing. Between 1901 and 1907, Macdougall conducted this experiment with six terminal patients. Four of them had tuberculous, one was diabetic and the other had no specified causes. They were chosen conscientiously and should be people who had conditions that depleted them mentally. They had to move as little as possible when they died so that the measurement was more precise. Macdougall was pending at all times of those final moments of the patients and, when he detected that one was about to die, he placed the bed on the scale and made the measurements. And the results soon arrived. According to the doctor, the first patient lost, exactly, 21,26 grams just after exhalation. It is the most famous case and the one that gave name to the experiment. The second patient also lost weight, but the amount was not recorded correctly. And with the other four … Things were even more complicated: the technical problems when registering the weight appeared for two other records, another showed a gradual loss (he died with his mouth open and Macdougall said it could be air) and another showed no changes. For any scientific eye, the success of the experiment would have been very questionable, but the doctor clung to those 21 grams of the first death to affirm that this was what weighed the soul. In fact, he did not stay at Anecdote: he published a study in the magazine American Medicine with the title “Hypothesis Concering Soul Substance Together With Experimental Evidence of the Existence of Such Substance”, although before it had already appeared in the New York Times. With animals, MacDougall went from thread Although MacDougall ‘chained’ that data, in his internal jurisdiction he should know that he needed another control group. If it had taken six years to weigh six dying, I could not “waste” more time, so he tried to try his theory with animals. There was some red flag in all this. The New York Times article published before the scientific article To begin with, Macdougall was convinced that humans had a soul, something that animals lacked. He had already observed “problems” when measuring the weight of the human soul, so everything that was a scale without measurement changes in the case of animals, he would take it as confirmation that, indeed, animals had no soul. The experiment was already conditioned and Macdougall ended up measuring the weight of a fortnight of dogs. The researcher wanted to use sick or dying dogs to prove his thesis, but did not find enough and There are those who point that, directly, poisoned healthy dogs. Scientific community with the lifted eyebrow The doctor’s results were not long in causing a stir and there was another doctor who considered the experiment a hoax. Augustus P. Clarke argument That everything was easily refatible from the medical point of view: when we are in that situation, the lungs stop cooling the blood, the body temperature increases and the skin sweats. And in the case of animals, as they do not have sweat glands, because they do not lose weight after death. Macdougall did not convince and starred in a ‘Beef’ in medical magazines for a few months. Over time, other scientists joined the MacDougall Experiment Discrediting process, being a clear case of rejection by the scientific community both for the methods and for the “fraud” when obtaining the results. Apart from randomness, One of the criticism is that six cases do not represent a reliable sample. In fact, in A subsequent investigation With sheep, lambs and rams, it was observed that, indeed, the weight varied after death, but they did not lose it: they won it. Specifically, from 18 to 780 grams that they won at the time of death, but that over time lost to recover the initial weight. However, it is undeniable that Duncan went down in history. Not for what I would have liked, be that person who showed that the human soul had a weightbut as an example of Selective informationhow to use a vague fact to affirm a preconceived idea. Also by that scientific spirit that, although poorly applied, tried to use evidence to measure something as … Read more

Two ways to look for the same

by

In any pharmacy, supermarket or Reel Instagram, supplements have become impossible to ignore. They are in capsules and powders with fruit flavor, but also in coffees, snacks and smoothies. Promise everything: more energy, Best dream, Less stress, most defined muscles either Even more luminous skin. But not everyone takes care of it. While some consumers of more than 50 years trust pills and anti -aging protocols, the youngest look for the same effect on a coffee or snack. The gap is not in whether or not they take supplements, but in how they are taken. Two formats, two generations. On the one hand, a more adult audience trusts that well-being has become a medical-aesthetic plan. In a report for Wall Street Journalmany patients come to consultation due to hair loss or wrinkles, and in addition to Plastic surgeries either “liquid surgeries”are supported by multivitamin capsules, Omega-3, collagen, probiotics or the increasingly popular NAD+. Specifically, in Spain, 75 % of the population has taken some supplementso the phenomenon is booming. On the other hand, As The Food Institute has detailedmillennials and gene generation reject the ritual of the pill bottle. They are looking more towards a practice that they consider more “natural”, that is, through food: enriched coffees, protein pancakes, fiber soft drinks either electrolytes. Its motivation is not so much to stop aging as optimizing daily energy, managing stress and fitting extra nutrition in your lifestyle. Improve health or fear of age? It is being observed with aesthetic changes, but supplements are a reflection of a cultural obsession. NAD+ is sold as the “antiaging” supplement par excellence: When restoring cell levels, it promises energy and youth. Saranya Wyles dermatologist has pointed out That their oral precursors could even protect high -risk patients against skin cancer, although it warns that visible changes are not always dramatic. In parallel, the gene z does not speak of wrinkles but of daily performance: feeling with energy in the university, managing stress or regulating the menstrual cycle. In the middle, critical voices. Rocío Périz, hormonal health expert, alert: “The danger of nutrichetic is not in its existence, but in the use we make of it. People take supplements without conscience.” He believes that the key is in education and personalization: not all supplements are worth everyone, and more doses does not mean more effect. In short, some fear aging, others seek to live the present better, but both groups pursue the same: control their body from within. Are the gene z correct? The short answer: it depends. Whenever you can, nutrients should arrive through food. Comprehensive foods They are not just a “bearer”for example, a salmon fillet provides Omega-3, but also protein, vitamin D, selenium and other compounds that act jointly and that it is impossible to reproduce in a pill. Now, According to the webmd medical portalthere are circumstances in which the diet is not enough and supplementation does make sense. The reasons are varied: folic acid in pregnant women, vitamin D in winter, vitamin B12 for vegans or elderly and even probiotics. In those cases, supplement is not a luxury but a medical tool. The key difference is the reason: in a healthy person with a varied diet, the multivitamin barely have proven effect. In fact, the Spanish Society of Endocrinology and Nutrition Explain: “Much demand, little efficiency.” On the other hand, in someone with a documented deficit, a supplement can be decisive. Something that nobody tells you. The enthusiasm for supplements usually leave in the background a key aspect: security. Here the dose is everything and not exceed what is indicated on the label or what a professional advises. The problem is that many times the line between the useful and the harmful is thinner than we think. The examples abound. NAD+ himself It has generated reports Of palpitations when administered intravenously, another ingredient is the glutathion that in excess can damage the liver and kidneys. Even astaxantine, sold as natural antioxidant, can cause orange skin, digestive discomfort or low blood pressure if abused. In the case of fat -soluble vitamins (A, D, E and K) Nor are they exempt from risk: By accumulating in tissues they can cause from dizziness to organ calcification. The last risk is less visible but equally real: marketing without filter. In social networks, the claims of “detox”, “natural” or “strength of the immune system”, terms that have no clear scientific definition and that, that, as BBC warnsThey usually escape regulation. And the border is blurred: those same labels now appear in functional cafes, gomolas “glow” or beaten with Claims impossible. What counts. In the end, either in a bottle or in a coffee with protein, what we are looking for is the same: feeling better, seeing ourselves younger or having more energy. The difference is how we integrate it and in what expectations we put. Science insists on an order: eat well, move, sleep, handle stress. Only later, and with criteria, consider a supplement. The future does not seem to be a miraculous pill, but specific, personalized and, above all, justified formulas. Until then, the decision to open a boat should go through fashion and more for evidence.

Europe is still a puzzle

by

30 European technological journalists sit in a meeting room in Munich looking at Zaheed SaburSenior director of Engineering at Google Gemini, already Terrence XiaoSenior Director of Product Marketing of Xiaomi. We are in the question and answers session after the presentation of the Xiaomi 15tbut the interesting thing goes beyond the mobile or the fridge: here we have talked about all that friction inherent to the Western Expansion project of the Chinese brand. The first crack appears when someone asks for Ireland. He Xiaomi 15t Prothe star model with its periscopic teleobjective of five optical increases, will not reach the Irish market. The Executive of Xiaomi dodges with diplomacy: “There are complicated factors that include business decisions and local regulations.” Translation: The fragmented European market remains a logistics and regulatory puzzle That not even Xiaomi, with all its ambition, has finished solving. Zaheed Sabur. Image: Xataka. When a Slovak journalist asks about Bugs persistent in Hyperos “Some have been dragged for some time,” silence is revealing. “It is a great priority for us,” says Terrence, promising to take the topic to the PR team. But the underlying reality is more complex: building an Apple -type closed ecosystem requires perfection in the execution that Xiaomi has not yet achieved. They are and it is fair to recognize that the future perspective is good if we see the evolution that the brand has had in the last decade. The drama appears when someone mentions the ads in the operating system. The answer is an exercise of balancing: the ads allow to offer devices at competitive prices (true), but erode the premium experience that Xiaomi tries to project with higher products. Zaheed Sabur takes the floor when the conversation derives towards AI. “The priority is not to discover the monetization plan,” he says, “but to create value for the user.” It is a statement that sounds noble but hides a more raw reality: Google and Xiaomi are in a career against time to justify the huge investments in AI before investors lose patience. Although it is fair to recognize that companies such as Google or Xiaomi can better allow these investments, each to their extent, when obtaining income from other roads. And speaking of the subject, the integration of Gemini In the Xiaomi it actually goes from Google ensuring distribution beyond the Pixel ecosystem, and Xiaomi obtaining AI capabilities without the prohibitive cost of developing them internally. When Sabur mentions that AI processing costs have fallen significantly, it is subtly revealing why these functions are still free: it is cheaper to subsidize them than to lose the ecosystems war. “We have no definitive plans not to launch a new Flip In global markets, “says Terrence Xiao when asked about folding. Double denial usually betrays uncertainty. Samsung dominates the Premium folding segment in Europebut Xiaomi seems paralyzed between launching a product that could cannibalize its traditional sales or completely yield that market segment. And from there we talk about cameras. The association with Leica is no accident. In a world where Mediatek has reached almost parity with Qualcomm (the Dimensity 9400+ of the 15T Pro is a processor beast), and where the amoled screens of 3,200 nits are Commoditycomputational photography is one of the few fields where there is still margin to differentiate. Terrence to the left, Zaheed to the right. Image: Xataka. But even here there are limitations. When they ask why they cannot record 4K at 60 fps with full zoom, the answer is limited to saying that “the video recording experience is something very important for us,” says Xiao, without explaining real technical limitations: real -time image processing remains a bottleneck even for the most advanced chips. The most incisive question: why not include magnetic load Qi 2? “It’s something we are receiving a lot feedback“, admits the Executive of Xiaomi. The non-response is eloquent: adding magnets would interfere with the complex antennas system that Xiaomi promotes as a differentiator (the Xiaomi arises t1s Tuner and the Super Antenna Array), but admitting it would be to recognize that they are trapped between physics and market expectations. The Xiaomi Offline Communication, which allows direct communication between devices up to 1.9 kilometers without a mobile network, is technically fascinating and very interesting if we scratch a bit: it is a function designed for markets with poor infrastructure or for emergency situations, transplanted to European markets where the 5G coverage is ubiquitous. Is Xiaomi trying to be all for everyoneand ending with functions that impress in the presentations but that 99% of users will never use. In any case, Xiaomi’s best play is not at 15T. It is in that 502 -liter mijia fridge and that washing machine with AI That detects fabrics. Terrence lets you glimpse when talking about the ecosystem: each device reinforces others, increasing the psychological and economic cost of changing brands. Terrence Xiao. Image: Xataka. But here the final paradox arises: Xiaomi needs you to trust its brand enough to put an 85 kilos washer in your home, while simultaneously it cannot guarantee that the Bugs of software reported two years ago they will be solved soon. It is asking for an act of technological faith. The presentation in Munich was not on phones with Leica cameras or mediatek processors. It was about a Chinese company trying to conquer European households while overcoming regulatory, cultural and technical complexities of a continent that still see with suspicion the technology that comes from the east, although less and less. The 15t They are impressive, yes. But They are just the Trojan horse for something much more ambitious And, precisely because of that, much more uncertain.

Bill Gates had a tendency to procrastination until he found an infallible remedy: Japanese companies

by

Bill Gates is not only famous for his work at the head of Microsoft, but for its enormous commitment and Requirement in the workplace. This demand reached such extremes that he was even able to Memorize cars registration that they had parked in front of the Microsoft headquarters to know which employees were still in the office and those who had gone home. However, the founding millionaire was not always so diligent with his tasks and, as confessed in his latest autobiographical book ‘Code Source: My beginnings’I had the bad habit of hurry the time to study just before the exam. However, over time, and some help from the Japanese, he learned that postponing the tasks was not viable if he wanted to take Microsoft to fruition. Gates’s youth in Harvard Bill Gates reported in his book how his university years in Harvard were marked by the habit of skipping classes and postponing any academic responsibility. His strategy was to study thoroughly only a few hours before exams, a dynamic that he shared with Steve Ballmer, his partner in Harvard and Microsoft command successor years later. “Steve and I paid very little to our classes, and then” we “furiously” Magnate in his book. Both felt comfortable challenging the limits and seeking to approve with the lowest possible effort investment. Gates came to recognize that they faced each exam as an experiment to check how far the good results could go with the minimum effort. This habit of delaying the tasks did not stay at the university, and soon moved to its professional beginnings after the Microsoft foundation. In his 1996 book, “Way to the future“Gates publicly admitted that That bad habit to postpone the tasks until the last moment became a real problem when the company grows. With his attitude, the millionaire not only slowed his work, but also had an impact on Productivity and motivation of the rest of your team. Delaying decisions began to directly affect the morals, mood and results of those who worked with him. “After Paúl Allen and I founded Microsoft, I discovered that developing the habit of delaying things had not been the best preparation to direct a company,” Gates said in his book. Gates himself estimated that he needed “a couple of years” to overcome what he called an “insane cycle”, in which he was lagging behind and generated an unavailable environment for his collaborators. The impact of Japanese customers Although in those days Gates was already beginning to be aware of his problem with procrastination in his tasks, he finished convincing when Microsoft began working with Japanese clients. In his book he pointed out that the relationship with Japanese companies played a crucial role in the process of changing habits. These companies, known for their discipline and iron control of the deadlines, did not tolerate delays. “Among the first Microsoft clients were Japanese companies so methodical that, as soon as we delayed a minute with respect to programming, they sent someone by plane to watch us, as if we were children. They knew perfectly that their man could not help us at all, but remained in our office 18 hours a day to show us how much the subject cared,” the millionaire wrote. “ Gates remembered that delaying with Japanese companies was “somewhat painful” so that external rigor and the pressure of having a vigilante all day attached like a shadow, was the revulsive that Gates needed to modify your time management. The millionaire assured that the process to leave the procrastination behind required a deep Review of your personal routines and professionals. Gates demonstrated that, although the transformation was not immediate, the Derived learning of those demands and rigor of its Japanese customers It was decisive to redefine both its personal development and Microsoft’s work culture.
