Pontegadea turns Luxembourg into the new homeland for the Empire of the brick of Amancio Ortega in Europe

by

Pontegadea, the Real Estate Holding of Amancio Ortega, It has grown so much In recent years that he has had to review his management strategy for the company’s European assets. Given this change of structure, the company has taken advantage of centralize management Of all the real estate holding company, making the one that until now was the subsidiary of Luxembourg in its new international headquarters. Luxembourg, the new Pontegadea headquarters. Amancio Ortega has completely reorganized the operational structure of its real estate holding company in Europe to convert its subsidiary Pontegadea Luxembourg into a giant that will manage real estate assets worth 7,033 million euros. However, although restructuring has been completed in 2025, it has been forging since 2024, as confirmed From Pontegadea EuropePress. The decision that has encouraged this change is that the great duchy is in a geographical position closer to the assets that it manages, in addition to having a much more friendly taxation for the taxation of the large real estate operations. Expansion under the structure of Luxembourg. In January 2023, Pontegadea registered the Luxembourg subsidiary to, throughout 2024, make several purchases of strategic real estate such as the offices of the Clifford Chance firm or the purchase of two more office buildings more worth 321 million euros. The luxembourgish subsidiary has absorbed the French, and takes control of all the residential buildingshotels, logistics centers and shopping centers that the company has in Germany, France, Ireland, Italy or Netherlands. In addition, it will also take control of the management of some assets in Canada and the United States. Spain, Portugal and the United Kingdom stay out. Despite its proximity, the assets that Amancio Ortega bought in Spain and Portugal, as well as The properties of the subsidiary Pontegadea in the United Kingdom remain outside this luxembourg dependent reorganization, and remain under the umbrella of Pontegadea investments. Under Pontegadea investments, 50.01% of the participation of Amancio Ortega en Inditex, Telxius, the telecommunications company that shares with Telefonica, and the entire investment arm in investment in Renewable energy and natural gas that the company has in Spain and Portugal. Why Luxembourg? The short response is for taxation. The long answer is that, the Pontegadea model does not consist of obtaining surplus value of real estate, but of become the landlord of important companies such as Amazon, Apple, Meta or Spotify, as well as renting their buildings To large hotel chains so that they exploit it commercially. All those rental income They are taxed in the countries where the properties are located, but Luxembourg’s fiscal advantage lies in a low tax burden when buying those properties. Amancio Ortega goes shopping in Europe. With this movement, Pontegadea has laid the foundations to begin its expansion throughout Europe, as demonstrated by the latest movements with the Purchase of an office building in the port area of Dublin for 70 million dollars; with the acquisition of the headquarters of the Editorial Planeta in Barcelona for 250 million euros; wave recent acquisition of the Luxury Banke hotel in Paris, for 97 million euros. Both the Dublin building and that of Paris, have directly passed to the Pontegadea Luxembourg asset portfolio. With assets valued at more than 110,000 million euros, Pontegadea has become the largest real estate in Spain, surpassing giants in the sector as colonial or Merlin. With this strategic movement towards Luxembourg, the investment arm of Amancio Ortega prepares to advise a blow to the European real estate market and position itself among the largest in the old continent.

It turns out that it is destroying innovation

by

In recent years, many companies have sought formulas to convince their employees to return to offices. The main argument to justify that return to face -to -face was the loss of Equipment cohesion But, above all, the assumption Freezo to innovation and the productivity that Telework had meant. To appease the employees that they raised in rebellion, the companies implemented Hybrid Day Modelswhich has ended up being the Type of majority day. A Published study In Nature magazine he has just demonstrated that this type of day was the worst option for employees to generate new ideas. Hybrid work: the hook to return to the office. The hybrid work model, which allows us to work a few days from home and others from the office, has been presented as the ideal solution for combine the best of both worlds However, a recent study by researchers from the universities of Essex and Chicago maintains that this modality could be having A negative effect Unexpected: Innovation in organizations is braking. The Promise of hybrid work has been raised as A reward For whom They accept to return to the officeallowing them to telework between one and four days per week. The study analyzes work habits and its impact on the generation of ideas, and reveals that the hybrid model not only does not improve innovation, but also reduces it. The hybrid model: the most implemented and ineffective option. According to data from the ‘Hays Guide of the labor market 2025’42% of companies have opted for this model of day with a series of face -to -face and others remote days. The research was carried out with “highly trained technology professionals; practically all have university or advanced titles in an engineering field” working in HCl Technologies, a technological company in India. The study indicates that “during the next hybrid period, the new ideas generation rate decreased.” In addition, it is concluded that “an employee takes about 111 months, or a little over 9 years, generate an idea.” During hybrid work, employees generated an average of 0.007 ideas per month (143 months or just under 12 years). The model that best lent to the generation of ideas was the 100% face -to -face model, but the results They were very similar to those shown by those workers who made their day 100% remotely. The importance of being in the same space. Researchers highlight that innovation usually arises from “random and spontaneous interactions among employees.” These interactions can be given both in physical spaces, as well as the office cafeteriaas in virtual environments, through chats or informal channels. Both work in the office and 100% remote allow employees to share the same space (physical or virtual) and, therefore, facilitate these coincidences and the generation of ideas. In this way, both the face -to -face and remote model can adapt to encourage the generation of ideas through common spaces. On the other hand, in the hybrid model, “an additional coordination problem arises if some employees are in ‘virtual coffee shops’ while others are in real coffee shops“This makes it difficult for all members to coincide in the same space and at the same time, which reduces spontaneous interaction opportunities. Where is my team? The researchers emphasize that “innovation falls particularly abruptly in teams that vary greatly between being at home and the office, compared to the less scattered equipment.” Thus, while office employees can Talk to each other In person, remote employees have the tools to generate these online conversations, and “programming a conversation can be more difficult in hybrid mode.” This lack of coincidence and coordination not only translates into a lower generation of ideas, their quality is also reduced.

We believed that the nasal strips had died in the 90. It turns out that they were just waiting for Instagram to get them fashionable

by

The small adhesive bands that stick in the nose are again very common on slopes, gyms and popular races after decades of oblivion. Why is it important. From Carlos Alcaraz Even weekend runners, the phenomenon of nostrils has exploded in the last year. It is no accident: It reflects both the obsessive search for marginal advantages in sport … … as our complex relationship with Gadgets –electronic or not– that promise instant improvements. The context. The nasal strips were born in the 80s as an antironquid remedy. They jumped to sport in the mid -90s when Jerry Rice wore them in the Super Bowl (today keep entering money by promoting them) and Ronaldo popularized them in football. They promised to “increase the nasal air flow by 31%” and became the sports avant -garde symbol of the time. And they went down in cascade, reaching the semi -professional and also to the amateur who simply wanted to leverage them to increase their performance. The fall. By 2000, science began to disassemble them. A study by the University of Buffalo with 13 athletes He concluded that they did not improve performance in intense exercises. The reason is simple: when the effort goes up, we breathe through the mouth, not by the nose. The strips became irrelevant. The return. Carlos Alcaraz took them A month ago in the Masters of Romeand in addition to black color: even more evident than the classic shiver. Several Barça players uploaded a photo on a planeall with the strips set, to “improve rest.” And new companies such as Gudslip or histrips have “reversed” them with somewhat more comfortable designs and marketing aimed at athletes of all levels. Also with Machacona advertising on Instagram. Yes, but. A 2021 review which analyzed 19 studies did not find significant differences in Vo2max –A key metric–, heart rate or performance. The strips reduce nasal resistance, but only help in light efforts or when there is congestion. In intense exercise, they are useless. For elite athletes, any 1% improvement can be decisive. Alcaraz uses them strategically when it is congested. Amateurs, less accustomed to extreme suffering, can perceive greater subjective benefit in respiratory comfort. In fact, who writes these lines tested them and the highest air entry is noticed. But not the remarkable improvement in performance. And we must not lose sight of the mental factor: in sport, there is very often a psychological component in certain practices. The use of strips can give mental confidence, reduce pre-compensation stress and be part of the ritual that reassures the athlete, which makes him feel control. What is happening. There are five great forces promoting this boom: Greater conscience that once on nasal breathing in sport. Products that have improved: grip, comfort and even appearance. Virality in social networks. Examples in elite sport. And low risk profile. On the latter: the strips of certain brands usually cost between and one euro the unit. They are a performance experiment that comes out cheap. Deepen. The strips do work during sleep. They reduce snoring and improve rest. For athletes with rhinitis or exercise induced asthma, they can be useful. In healthy people doing intense sports, its effect is mainly placebo. Abel Antón, who won World Cups with and without them, summarizes it in a phrase pronounced a Relief Two years ago: “Believing that something is doing well makes us work much better.” Outstanding image | Pneuma Nasal Tape In Xataka | I have run, swim and worked with the Aqua Suunto.

We had been thinking that creatine served to train better. It turns out that the greatest benefit was in the brain

by

Creatine is the star sports supplement and one of the most studied. As with the coffee and caffeineis surrounded by Myths And we have been investigating its benefits for decades when practicing sports. AND studies More recent have placed up to creatine supplementation by pointing out that the muscles are not the only ones that benefit from their effects. The brain also appreciates it. Physical performance. Creatine is a nitrogen compound that occurs mainly in the liver and that humans also obtain through the consumption of meat and fish. Although there is controversial studies in this regardcreatine really is stored in the form of phosphocreatine, acting as a booking Immediate energy. This means that, when the muscles are subject to intense efforts such as a sprint or a weightlifting, phosphocreatine acts to regenerate the essential energy molecule for muscle contraction. This allows muscles to maintain high performance for a little longer. It also increases cell hydration and stimulates protein synthesis that leads to cell growth. Enhancing the brain. Being such an studied supplement implies that numerous ways have been found in which creatine benefits our body, reducing inflammation, oxidative stress and muscle catabolism. And, along the way, they have found benefits additional that have not to do with the growth of our most ‘visible’ muscles. It is increasingly recognized for its general health benefits, including cognitive function and healthy aging. Although the brain is not a muscle, it also stores creatine and can benefit from its energy effects, such as supplying energy quickly to neurons. A applicationfor example, it is the good brain function in times of lack of sleep. Essential. This is something observed in several investigations, being carried out by the team of Dr. Richard Kreider, director of the Exercise and Sports Nutrition Laboratory of the Texas A&M Universityone of the last to contribute to the conversation about its benefits. According to Kreider, the regenerative paper and as a rapid “fuel” is relevant for both muscle and brain. “When the body is stressed, as in exercise or in metabolic conditions such as those caused by some diseases, phosphocreatine is needed to maintain cellular energy,” says Kreider. Neuroprotection. Others studies They point to added benefits, such as acting as a neuroprotective, helping in the recovery of brain injuries and showing potential to reduce mitochondrial dysfunction, key factor in neurodegenerative diseases. It also helps reduce the feeling of tiredness, maintaining alert and performance in demanding cognitive tasks. How much? One of the big questions when creatine begins to be taken how much is necessary to fulfill its function correctly. It has been experienced with several doses and there is a kind of agreement that would have to be taken between 0.07 and 0.1 grams per kilo of weight per day to optimize physical performance. For a 70 kilos person, this is equivalent to 5-7 grams per day. Kreider fits those accounts by resorting to that ‘cycling’ practice that was recommended a few years ago. Thus, the researcher indicates that about 20 grams would have to be taken daily for a week to “help load the muscle”, but later it could be taken between 5 and 10 grams a day to maintain creatine reserves that contribute both to the muscle and the brain. In Vegans and vegetariansIn addition, it is essential because for a omnivore It is difficult to fill the phosphocreatine reserves with your diet, not consuming meat or fish the difficulty is even greater. Security. Due to the myths that we commented before (such as hair loss or that it is an anabolic substance, among many other discharges about creatine), it is easy for people to not trust this supplement. Kreider states that “there is absolutely no data that supports any negative side effect reported anecdotally on creatine,” reaffirming that it is “safe and important to all, not only for bodybuilders and athletes.” Images | Xataka, Scientifanimations In Xataka | Tell me what color is your banana and I will tell you what it is for: the importance of maturation point at nutritional level

I have played the ‘Nintendo Switch 2 Welcomme Tour’ thinking that it was a payment manual. It turns out that it is a science museum

by

The presentation of Nintendo Switch 2 In April it was curious. In the event they revealed a lot of details and interesting games that excited the players, but after it, the Batacazo arrived. The console prices, of games and accessories. The monetary hangover lasted a few days and the lace was the ‘Nintendo Switch 2 Welcomo Tour’. This collection of mini -games was like the “manual” of switch 2 … of payment. 9.99 euros, specifically. It is not something I like in the community, but after trying it, I am clear that it is much more than a Nintendo Switch 2 user guide. 1-2 switch. When a console arrives with innovative characteristics, the best way to test them is through demos. With the launch of Switch in 2017Nintendo came up to launch a game that, for 19.99 euros, allowed to experiment with the control infrared sensor, with the HD vibration or with the movement sensors. Called ‘1-2 switch‘, it was curious, but nothing more, and accompanied in the launch of the machine by’ The Legend of Zelda: Breath of the Wild ‘, because little attention was going to monopolize beyond the one granted by curious eyes. Welcome to Switch 2. literally. Nintendo Switch 2 is not that it is the pinnacle of innovation. It is a rather continuous console, than It is just what Nintendo needs After the resounding success of the predecessor, but as they know that many people may want to get on the train of the new switch, they have prepared something similar to ‘1-2 Switch’: ‘Nintendo Switch 2 Welcome Tour’. The problem? That since it was announced, this collection of mini -games to know the technical details of the machine was more like a manual than as a video game. And, worse: a payment manual. I’m already Testing Nintendo Switch 2 for analysisI have mine on the way and what was clear was that this game did not call me or the least. Luckily I had to play it to see how wrong I was. A Science Museum. Because … yes and no. ‘Welcomome Tour’ is the console manual as long as it teaches us all the details of it. We review the command, we review the screen, all the buttons of the Joy-Con and every millimeter of the system and some of its peripherals, but we do it as if we were in a museum. As a child, the museums bored me, but when my parents took me to a Science Museumthe thing changed. That of pulling levers, moving a giant wave, seeing gears and ‘moves’ in motion was something that excited me. And, precisely, that is this game. We chose an avatar, we queue to enter a Nintendo Switch 2 giant and Ale, to explore. Each piece of the system has an information panel that rewards us if we find it, there are mini -games that allow us to explore how certain buttons and modes and also informative panels are used on hardware elements. If we want, we can spend a kind of exam to get prizes and move on the virtual console, and it really is fun. Cheat. At this point, I know how haptic vibration works, I know how the optical sensor allows the joy-with in mouse mode (very precise, by the waybut incompatible with some hands) and they will not discover anything at the technical level of the machine, but without being the target user of this, I have fun collecting the collectibles, and beyond for this test, I will continue playing. I think that, in addition, it can be a very didactic title for all types of audiences that buy the console and want to learn more about it and about technology in general. In addition to enjoying seeing how they explain one thing and, to the second, you can put that into practice. The problem is that … well, there are two problems. And it comes with controversy. One is that you cannot get 100% of the game only with the console and the Joy-Con. There are some mini -games and demonstrations that require a 4K television that can be common in homesbut … there are also those who need the Pro command (90 euros) and the camera (another 60 euros). Nintendo already specifies it in the game website With a “for certain technical demonstrations, additional accessories are required, for sale separately”, but it is curious. Minigame to test the mouse mode And another to experience vibration Oh, the precedents … And the second controversy comes with the price. Not so much for having to pay those 10 euros, but because it will mean a barrier for many people to enjoy this title. With the launch of PlayStation 5Sony included a demo, that of ‘Astro’s Playroom‘. Not only was it a precious tribute to the history of PlayStation, but a really fun platform video game. Liked that their developers had green light to develop a complete game, ‘Astro Bot‘, who ended up taking the award to’ Best Game ‘in the’The Game Awards‘of 2024. ‘Nintendo Switch 2: Welcome Tour’ would have been not only a perfect gift for Nintendo Switch 2 buyers to have something to play as soon as the console should turn on, but also the opportunity for more people to discover this game so curious and ‘cuckoo’ in which a few developers have been working. Because it shows that there is a lot of love in this “payment manual”, but precisely that it is paid and that it looks like a manual is what can be a wall for many users. And it’s not just ‘Asto’s Playroom’: Wii had ‘Wii Sports‘Included, and it was a huge pilar on which The success of the console was cemented.

In 1963 we discovered a pre -Columbian city hidden in the jungle of Peru. It turns out that we only knew the tip of the iceberg

by

Between the VII and XVI centuries the northeastern Andes of what is today Peru saw a rich civilization that planted the Incas: The Chachapoyasthe “cloud forest people.” There, between 2,000 and 3,000 meters above sea level, its people raised funeral and ceremonial constructions that over the centuries ended up devoured by weeds. One of his greatest legacies is Great Pajaténin the San Martín region. Archaeologists have known him for decades, but when studying it with new techniques, such as Lidar scanthey have been surprised. They knew only a small part of the complex. What they have found is so interesting that the World Monuments Fund (WMF) He already speaks of the greatest archaeological milestone in the region since the 80s. What happened? That Peru has just given a pleasant surprise to historians. Especially those dedicated to the study of pre -Hispanic civilizations. A few days ago the WMF) revealed that a group of researchers have identified and documented more than a hundred archaeological structures in the Great Pajaténone of the most important archaeological deposits of ABISEO RIVER NATIONAL PARKin the Peruvian Amazon. In fact It is also known as “the lost city of the Chachapoya” or “El Dorado del Antisuyo”. Why is it important? For several reasons. The study not only provides information that helps understand the settlement. It also helps us to know better the civilization to which it represents: The Chachapoya (“People of the cloud forest”), a pre -Columbian culture that flourished between The VII and XVI centuries and shone among other issues for its constructions, such as the impressive Kuelap fortressa citadel located at 3,000 meters above sea level in what is now the Luya province; or the Great Pajaténwith its circular stone buildings, decorated terraces, winding paths and platforms. And who were the Chachapoya? An outstanding part of the history of ancient Peru. As Remember the WMFthe civilization flourished between the VII and XVI in the northeastern Andes of what is now Peru, organizing around regional manors. Despite the steep terrain they managed to adapt and demonstrate their ability as architects: they built settlements with characteristic circular, friez and mausoleum constructions. Not just that. They also managed to resist the thrust of the Inca, although they ended up subjected in the fifteenth century. What have they discovered exactly? The Great Pajatén is known For decadesis in an environment cataloged by UNESCO And archaeologists had already been in charge of examining it before. In fact, in the 60s they documented 18 structures and time later, in the 80s, they expanded the list to the 26 elements. Now the experts They have discovered that was just the tip of the iceberg. With the help of new techniques and resources, the expedition led by the WMF has identified more than 100 archaeological structures that give a new dimension to the settlement. So relevant is the finding that the organism speaks of the “first important discovery in the region since the 1980s.” “More than duplicate the number of known archaeological structures”, celebrate. What tells us all about the great Pajatén? A lot. The site It was discovered In 1963 And since then archaeologists consider it “one of the most notable Chachapoya sites that are preserved”, with ceremonial buildings decorated with friezes and stone mosaics that represent human figures. The problem is that experts failed to make an overall image of the Chachapoya complex or its reach. The reason? Much of its architecture was still hidden, covered by the lush vegetation of the Peruvian high jungle. That handicap and the lack of perspective had so far conditioned the image that experts had of the deposit. “Its scale, function and chronology were subject to continuous speculation”, They point out from WMFwhich recalls the “unique and highly fragile ecosystem” that surrounds the settlement, in the Abyseo River Park. To shield it the authorities even restrict tourists’ access. And what conclusions have they taken? At the entrance, researchers have confirmed that the Chachapoya presence in large pajatén can be traced to the fourteenth century. And that at least. There are certain clues that suggest “a significantly earlier occupation.” During their expedition they also detected a nearby network of pre -Hispanic paths that connect the whole with the beach, papayas or slopes, which For the WMF It supports “a broader interpretation of the complex as part of a hierarchical and interconnected territory.” “The team documented an architectural set composed of multiple interconnected sectors. This allows us to understand the great Pajatén in its true magnitude, not as an isolated set, but as part of an articulated network of pre -Hispanic settlements of different periods,” Comment Juan Pablo de la Puente, WMF manager. “This finding radically changes the dimension of the site and raises new questions about the role of Pajatén in the Chachapoya world.” How have you discovered it? If great Pajatén has been known for more than half a century and until now the dense vegetation had prevented archaeologists from deepening their study, the following question is obvious: what has changed? Why have you discovered new constructions now? The answer is simple: experts have resorted to new tools that have allowed them to see through that green mantle without altering the environment or damaging structures. The key is in the Lidar scan aerial and manual, photogrammetry, topographic record and technomorphological analysis. Thanks to them, experts have been able to get up The dense mantle of vegetation to take a look at what is underneath, map everything, study the architectural techniques used in the settlement and how it adapts to its surroundings. “Everything without damaging the delicate landscape or its architectural vestiges”, insist From the International Federation. Have you done anything else? “Thanks to the use of advanced technology, our team was able to collect extraordinary visual and scientific documentation that gives life to the great Pajatén, preserving its delicate environment,” celebrateBénédicte de Montlaur, WMF president. “Although the site remains inaccessible to most people, these tools will allow us to share their meaning.” The … Read more

Costco turns ten in Spain. Has not yet won a single euro

by

Costco has completed a decade of operations in Spain without having declared benefits, and therefore, without having paid a single euro in companies, according to its annual accounts and what was published by Digital economy. The figure. 143 million euros. This is the accumulated amount of losses that the Spanish subsidiary of Costco has declared between 2014 and 2023. However, its sales have multiplied by five since 2017, reaching 544 million euros in 2023. It has also increased its physical presence with five new hypermarkets, plus two others under construction. It has expanded its partner base to 650,000 (24% more than the previous year). Employ 1,256 people in Spain. It is building A logistics center in Guadalajara where he has invested more than 50 million. Why is it important. This case is an example of a common strategy among multinationals: artificially maintain red numbers in specific markets to avoid local taxation, while their operations and market presence increase. The company itself acknowledges in its accounts that “it has not had to satisfy any amount for societies tax in Spain”, adding that its greatest contribution has been “the generation of local wealth.” The money trail. Costco does not publicly detail which mechanisms to maintain constant losses despite its growth, but the usual strategies include: Loans between subsidiaries with high interest. Canons for the use of brand, technology or know-how. Transfer prices in purchases to other subsidiaries. Strategic Business Costs. The trend. The US matrix continues with its expansion in Spain, despite losses. The group has reduced its red numbers up to 7.7 million in 2023 (its best historical result), and the company projects that will continue with losses “until it reaches a market penetration and sales level”. Said in Román Paladino: until it has grown enough. The general panoramic. This strategy is not exclusive to Costco. Large multinationals such as Amazon, Starbucks or Ikea have resorted to different fiscal engineering mechanisms To reduce their taxation in the countries where they operate, within legality but they are not some controversy. Meanwhile, the Spanish client seems oblivious to these fiscal ins and outs: the 650,000 members who pay their annual fee to access the costco prices continue to increase, a sign that their model works independently of the declared red figures.

It turns out that the myth that marriage fattens is true. But only for men

by

There is a preconceived and quite widespread idea that relates marriage to accumulating kilos. Well now a group of researchers has contrasted that this prejudice with respect to the marriage union is correct. Or at least correct. An unequal effect. A new study has observed that the risk of obesity increases significantly in men after marriage. It triples, in fact. The same study, however, did not find a significant change in this probability in the case of women. Of course, the risk of developing overweight did increase in both groups. The results must still be interpreted with some caution because the details of the study have not yet passed the scrutiny of peer review and publication in a scientific journal. Those responsible for the work will be presented by this spring in the 32nd European Congress on Obesity that will be held in Malaga in May. Why do we get fat? The question of why we get fat can have many answers. The simplest is that our body absorbs more calories than it burns, so stores energy in the form of fat. However, this is only part of the story: there are many genetic, environmental or socioeconomic factors that we know are, the less, correlated with our risk of developing overweight or obesity throughout our lives. Little by little we verify that marriage is one of them. 3.2 times higher risk. The study indicated that marriage multiplied by 3.2 the risk of men to develop obesity, while the effect of this union was not significant in the case of women. The risk analysis to develop overweight showed a less marked difference. The team responsible for the study observed A 62% increase in the risk of overweight in the case of men. A risk that in the case of women stayed at 39%. Multiple factors. The study analyzed other factors linked to this relationship, which showed other connections of interest. It was thus observed that some factors affected the risk of obesity in the case of women. For example, depression caused the risk to be folded, while lack of health in terms of health also increased risk in women by 43%. This type of factors and interconnections helps us understand what is happening behind the data. Even so, the hypotheses are diverse (and complementary). For example, Less physical activity by men And social pressure in the case of women can help us understand the unequal phenomenon. “Research also suggests that men may have greater propensity to gain weight after marriage due to factors such as an increase in portions, social meals, and a decrease in physical activity; while women may remain more aware of weight due to social pressures ” He pointed to the British newspaper The Guardian Katharine Jenner, director of Obesity Health Alliance. Also age of age. Another important factor to take into account was that of age, as it could foresee. The study showed that age affected the probability of developing overweight and obesity, and that in this case the effect was greater in women than in men. Thus, for example, the risk of obesity increased by 3% per year in the case of men and 4% per year in the case of women. Understanding the context. Understanding the effect of factors such as marriage can help us develop more effective policies to address obesity and overweight, with the ultimate goal of addressing public health problems such as the increase in some non -transmissible diseases for which obesity and overweight are risk factors.

It turns out that it is older than we thought

by

China is one of the greatest powers regarding megaconstructions. Their Bridges and skyscraper, Even abandonedthey are one of their hallmarks, and that fascination with monumental constructions is not new. Perhaps one of the most representative constructions of the country is the great wall, and although we thought that its more than 21,000 kilometers did not keep secrets, new studies They have shown that we were wrong. And it is not only older than we believed, but is protected by a ‘bioesk’. Rebobinando. The great wall rose to protect the northern border of the Chinese empire. For centuries, other civilizations sought to assault the empire, so the different dynasties were taking over adding sections on the wall. Until now, we thought that the works began at some point between 770 and 476 AC, but an investigation carried out between May and December 2024 by the Institute of Cultural Reliquias and Archeology of Shandong has advanced that date. He Institute He made an excavation that covered 1,100 m² in the town of Guangli that was fruits: they unearthed a section of the Great Wall that was 300 years older than the rest. Specifically, it would belong to the late Western Zhou dynasty, between 1046 and 771 AC Advanced Engineering. This new section, like so many others, was carried out in several phases: the early during the Zhou dynasty and the late, which would overlap with the stretch that we believed older so far. To date the discovery, the team took samples of soils, animals of animals, plant remains and discovered artifacts, carrying out the carbon-14 tests and optically stimulated luminescence test. And there was not only a wall: the civilization of the time was already thinking about large -scale fortification with trenches or pits. The best preserved part is the most recent of those discovered due to advances in construction techniques. During the first phases, used The land apison technique for the wall, but in the last one the compacted land was already used next to metal elements that improved its structure. On the width, it surprises that, while the current one has a width of about five meters, those sections were between 10 and 30 meters. Actually, the great wall is not a single wall, but numerous sections that each dynasty was building Changing the past. Beyond the particular discovery, which is older than we thought, has serious historical implications. As Comment Zhang his, leader of the research, the finding “marks a significant advance in the archeology of the great wall and is a milestone to clarify the origins and development of research for its construction.” The remains of the dynasty wall are not the same, 2,200 years ago … This is because, under this first part of the wall, archaeologists found foundations of two residences that also dated the Zhou dynasty. They estimate that these were semi -subject houses that could have been part of a small settlement linked to the defense of the nearby river. This river was vital for trade with other nearby areas and the decision to build the wall would have responded to the desire to shield the enclave. … that the remains of the most recent Ming wall Apart from the wall and residences, the Zhang team found an old nearby settlement: the city of Pinying that was mentioned in some historical texts. Uniting the points, the archaeologist considers that “his close relationship with Pinying indicates that the wall served not only as a defense mechanism, but as a strategic pillar in the control of the key transport routes” between that settlement, Pinying and other localities. Biocortex. Although discovering that the great wall is older than it was believed, it is the most interesting, it is not the only recent discovery about this megaconstruction. A study Published at the end of 2023, he revealed that several sections of the wall had a kind of shield, a ‘biocostra’ formed by tiny plants without roots and other microorganisms. This is not so weird in rocks and soils of dry areas, but as we read in CNNresearchers do not usually look for it in man -built structures. And, unlike plants whose roots can deteriorate monuments, this scab separates the rock from the air, water and wind, reducing the porosity of the structure and protecting it against elements and erosion. As if that were not enough, it also acts as ‘glue’, improving the resistance of the wall. Vegetation can damage the structure, but those yellowish spots are lichens that are part of biocoraza What is clear is that, the 641 kilometers of the section of the Great Wall of the Qin, a World Heritage for UNESCO, are no longer the oldest. But the most surprising thing is that the wall was building for a longer time than we believed: more than 1,000 years. They were the Ming who, in the mid -1600 AD, arrested their expansion after the annexation of Mongolia, which left the great wall without a defensive purpose.

We have been trying to reinvent the wheel for years. It turns out that it was as simple as replacing it with pilates balls

by

I have always seemed curious the saying “We are not going to reinvent the wheel.” It is used when trying to develop a solution from scratch instead of taking advantage of an already proven and works well. And I say it seems curious because We have reinvented the wheel On many occasions, and we continue to do so. Two examples are wheels without air And, above all, the solutions for vehicles operating on land like Mars. Although circulars, its technology and design have nothing to do with the wheels we use daily. And, okay, I accept that, being circular, we are really changing the materials, not reinventing the object. But what if instead of making circular wheels … we made them spherical? Because that is precisely what the engineer and youtuber James Bruton has built: some omnidirectional wheels that solve current problems They have motorcycles and that would also be very interesting if they apply to vehicles such as cars and trucks. Let’s welcome the wheel II To reinvent the wheel, the system should not be just an improved version of the original. As I commented, the Antipinhazos wheels They are not a completely reinvention, but a technological improvement. What Bruton has achieved could be described as a reinvention (although he has side more than one attempt). The reason? In its motorcycle prototype of the future, we not only have the two balls that make contact with the ground, but a system of three rotary mechanisms for each wheel that are really applying the necessary force to move the balls and, therefore, the vehicle. More than the spheres, the key to the peculiar movement of this vehicle are systems that rotate in opposite directions and all the time balance each other to achieve movement. Each of these mechanisms is driven by an electric motor that transfers the power, but also introduced a self -evaluated system similar to that of a Segway. In this way, it is not necessary to rely on the floor with the legs when the vehicle stops, and it is not necessary to maintain the balance in a “manual” way. Its advantages? You can go back without boosting with your legs. It has lateral displacement. You can make diagonals and turn on your axis. For a parking lot, this is great. In the video it is very interesting to see that the noise it makes is minimal, that it reaches some speed and that the mechanisms that rotate the balls are working all the time to give speed to the vehicle and to maintain balance. Imperfect, but with potential Now, it is not perfect. In the video we can see that the youtuber has trouble going straight and There seems to be a quite pronounced difficulty curve both to go forward and to take a curve. In a road situation, it would be something really dangerous because, in addition, we do not have a conventional handlebar, but a bar that remains fixed and controls rotating the handle. There is also a time when it accelerates more of the account and the balls are shot. Wow, something like that would need your own driver’s license if applied to the real world, but if the problems were solved, it is a very interesting system for motorcycles due to automatic balance. For cars and trucks it would not be a bad idea either, since they could park much more simplely. Seeing this invention, the Audi of the movie ‘I, robot’ that has similar wheels and It was a real prototype. Also the Byd video parking in parallel Thanks to nailing the front wheels and making the rear turn slowly to “skid” until the car is aligned in the parking lot. Will we adopt wheel one day like these? Whatever happens, the truth is that it is interesting how we continue to find new ways to improve something that has implanted so many years.
