Experience leaves difficult answers to ignore

He Free Freestyle 2 It is designed for those who need to control their glucose daily. But what if someone proves it In medical terms you do not need it? On this new 24/7 of the Xataka YouTube channel We have used it for more than a week to understand what it contains to live with that level of continuous control … even when there is no diagnosis behind. Mario Arroyo He has used it for more than seven days in a row, in all kinds of situations: from a copious meal to a paddle game or a night with unexpected dances. “O oysters! Eh, nothing hurts, nothing hurts.” The reaction was spontaneous and marked the tone of a test that did not intend to issue medical trials, but observe how such a device behaves outside the usual context. Freestyle Libre 2, Live with a 24 -hour glucose sensor The first thing that impresses with free freestyle 2 is its appearance. When opening the package and seeing the applicator, our partner’s reaction was clear: “God, what a piece of needle”But that feeling vanished to put it on. The process is fast, without pain. For a full week, it has even unnoticed when sleeping, exercising or showering. What seemed invasive, turned out to be comfortable. The sport also left its mark. After playing the paddle for two hours, the glucose level collapsed: from a normal value to only 57 mg/dl. Something similar happened at night, where several declines were detected without apparent cause. Three hypotheses were afloat: the soft diet for being sick, possible imprecise readings of the sensor or, ultimately, a body notice. At that point, the tool ceases to be just a curiosity. To what extent can we trust your alerts? Synchronizing the sensor with the mobile is as simple as approaching it for a few seconds. The app is updated every minute, showing the current value and its evolution with arrows. In addition, keep the record and allows you to consult the maximum and minimum daily. It is a tool designed for those who need to monitor their glucose, but its clarity makes any user interpret it. Does that constant information provide if you don’t depend on it. After eating a “normal” dish of about 70 grams of turkey rice, the glucose reached its highest peak of the day: 168 mg/dl. The fact, although within the expected, caught the attention for how fast it went up and how much it varied against the previous value. Measure before, just after and after two hours it allowed to visualize how the body responds. With the sensor, what was previously invisible is now drawn in real time. The sensor has an error margin of approximately 9.2%, according to the company that manufactures it. A reasonable fact for a system that does not require medical intervention. But the cost is another story. There are cheaper optionsand its price can be a real barrier. The question, then, is not only if it works, but for who works. Is it a useful tool for anyone or only for very specific profiles? After more than seven days with the sensor, the experience has been positive, although nuanced. He adds: “It seems to me a very comfortable device” and acknowledges: “I think that if you do not have a real problem of diabetes, its usefulness is somewhat limited.” Technology works, and works well. The complete analysis, with all the details, is in the last video of our YouTube channel. Images | Xataka In Xataka | I have used Ultrahuman glucometer for two weeks without being diabetic.

While giving us mobiles with better cameras, more power and a flood of AI, I just want them not to die in summer

by

In recent years we have seen huge advances in smartphones cameras, in His brilliant screenshis fast charge, Your powerand what they manage to do thanks to the progress that artificial intelligence has brought to the sector (now, not when it began to promote itself eight years ago). And yet, in a summer as hot as we are happening, what I miss most is being able to take advantage of all those functions. Because as temperatures are taking place since May in Andalusia, the reality is that I can’t. The problem. When the heat arrives, the girls fall in love and Solar panels have a fatal. It is also the worst enemy of modern smartphone, whose current functioning completely modifies. With high ambient temperature, smartphone begin to suffer thermal strangulation or Thermal Throttling. It is a technique that reduces the performance of the device so that it does not continue to warm up. What do we notice? In which everything is slow, getting to cause Lagand slowdown accused even in high -end mobiles that do not suffer with normal ambient temperatures even when we demand a lot. It is also common for smartphones to begin to deactivate functions that require greater consumption and therefore heating, such as high rates of soda (90 Hz, 120 Hz 0 more), fast charge or high brightness on the screens. The latter is especially unfortunate, because it is on sunny summer days (when we have more hours of sunshine) when we need the record shine peaks that manufacturers promote with each recent launch. The situation on extreme heat days. The last great heat of these weeks has been the perfect example of how smartphones suffer. In an encounter with friends in the field where there were smartphones of several major brands, the smartphones became unusable in the hottest hours. Fully attenuated and impossible screens to see the sun, abysmal performance, extremely hot bodies and worrying warnings of two types: impossibility of continuing to load to protect the battery, and complete smartphones blockages with a temperature warning as The one Apple details on its website. The first caused that we had to wait until sunset to load the smartphones (with the consequent complete download of several of them for hours) every day. The second, even losing calls: c on the very hot mobile, a relative called me, and the call was abruptly cut by showing a notice like the next. The situation is also improvable with more moderate temperatures. A heat wave in Andalusia is an exceptional situation and that is not lived in countless territories. However, in May, I was at an outdoor wedding about 25 degrees of temperature and decided to take photos and videos with an iPhone 16 Pro and a Samsung Galaxy S25 Ultra. The iPhone responded with Throttling, strongly attenuating the screen and slowing down any interaction with the interface. The Ultra Galaxy S25 responded something better, without being slow but also presenting little shine in its panel. The situation was paradoxical: I was using two of the smartphone with the best camera in the market, but I could barely record and take pictures, for the slowness with which they worked and because I almost did not see what I was shooting. Not because of the reflexes of the sun, but because of the little maximum shine of the screens once the terminals felt some heat. Another similar situation, changing camera for GPS, is what is lived in cars in summer: the mobile attenuates its screen and there are cases in which it costs to see the navigation interface, especially if at the same time we are carrying the terminal. And it is not trivial, we load them using the GPS because the consumption shoots and on a long trip the battery does not endure. Keys to protect them from heat. The solutions we have as users are, unfortunately, limited. But There are things we can do. For example, minimize its use in the sun. In summer, as we pointed out, it will be difficult, but there will be multiple situations in which we can place ourselves in the shade. Or what is easier: always leave the mobile in the shade, instead of at very hot points from a place in the sun, on the beach or in the car. They are not few occasions in which I have remembered acquaintances that his mobile would be burning because they had forgotten the sun. We can reduce camera use, especially when necessary. Sometimes, doing tourism, we tend to leave the screen on with the camera in use, preparing for a shot that sometimes does not arrive. It is in those situations when the terminal turns off until we have a shot to shoot can save a lot of heat. House and car tricks. My maximum advice is to use the terminal as GPS subject with a support for air conditioning ventilation grilles, so that it will be cool. It will load at normal speed and work as a browser without major problem. It is a advice that applies even if we use something like Carplay or Android Auto, as the vehicle will continue to resort to the terminal GPS, with the consequent heating. At home, two other tips that I have put into practice: use Cooling with integrated fan or even Cold accumulators covered with a trap that also greatly reduces the temperature of the smartphone when they come into contact with them. Thus they are trying to mitigate the problem. Manufacturers lead a lifetime fighting heat. The problem is that, at the same time, they are integrating components that, although they are more efficient than in previous generations, also have higher final consumption, especially when we think that more and more cameras, more bright screens and chips capable of Move AAA games (although The best is pulling streaming). He Xiaomi 15 Ultrafor example, he convinced us for how his cooling system with Steam camera three -dimensional manages to tame the Snapdragon … Read more

If the question is “how ancient Rome smelled” the answer is “yes”

by

Smelling a colony, a room or a plate of food causes our mind to jump and travel over time. It is something tremendously powerful And that has led to investigate ways to smell video games, The cinema either to the Internet. These systems existed And, although it would be the definitive immersive experience, None finished curdlingPerhaps the problem is that we don’t want to sniff certain things. And, definitely, something we would not want to experience is the smell of ancient Rome. It smelled strong. Thomas Derrick, a doctor at Macquarie University in Australia, believes that ancient Rome would have been extremely smelly for Anyone of today. In statements a RNZthe researcher specialized in people’s daily lives during that historical period in Rome believes that “it probably smelled quite bad.” Ok, but … to what extent? “You would smell human waste mixed with smoke resulting from the burning of firewood, animal droppings and other things rotting and decomposing.” And the sewers? The problem is that there was not a single source of those bad smells, being the result of a stinky combination not particularly pleasant. Rome had a sewer system (the ‘Maximum sewer‘It is an example), but not some sewers like the ones we can imagine to carry the waste of the latrines to a black well or something like that, but something more similar to a river drain to evacuate the stagnant water of the public areas. Derrick says in an article to The conversation that “we can assume, with enough security, that the owners did not have latrines connected to the sewers in the big cities, perhaps by fear of the entrance of rodents or the bad odors.” In addition, they did not have valves such as those that currently prevent things from the sewer, so the gases that originated from the waste, such as methane, could enter the houses. And considering that lamps with a flame were used, The danger of explosion was there. Nothing was wasted. Most likely, the most humble had a nearby black well. And, in addition to the feces, it must be taken into account that the garbage could also be thrown into the same place … or directly to the street, as was the case with urine, thrown from the windows of the buildings of several floors. Apart from human waste, there were work animals that were used regularly in cities that They did their things in the streetsas well as decomposition corpses of both these animals and people. And what is garbage for the vast majority, for others it is a “treasure.” There were professionals who collected stool to use them as fertilizers, but urine could also be used to wash clothes. That urine is still rich in ammonia, so could be used to disinfect. Patches for poop. If the streets were up of excrement (and what are not excrements, another question that arises is how they could walk through them without ending up to the stool knees. The answer they found was the placement of large stones in the streets to dodge both the mud and the waste. Pompeya is one of the places where you can see these “stones to cross”, a cobblestone that also allowed a simpler step for animals that were used to load or for tasks such as moving the large stone mills that were used in the bakeries. Again, more animals … and more waste. Humanity. Derrick says that this nausebound smell of the big Roman cities was not only due to the feces of each other. “Roman settlements would have strongly smelled of body sweat,” he says. Also demystify that Image of Roman public bathsaffirming that they were not as hygienic as we can think if we visited the ruins of some of them. And yes, although they were places where you could carry out hygienic activities, especially were meeting points in which it defined and ate, pulling the remains to the ground. In addition, although the Romans knew the soap, they preferred to scratch the skin with a bronze curved tool called strígile and use perfumed olive oil for personal hygiene. And the mixture of oil and dead skin was thrown (again) to the ground or water. And since water and oil are not mixed, when the water disappeared, only that greasy mejunje remained. The author comments that the bathrooms, “were surely quite dirty places.” That tool would be strígile There were always classes. The elites could have more refined customs and even use perfumes that, yes, existed in ancient Rome. To elaborate them, they mixed animal and plant fats and they were impregnated with aromas such as roses, cinnamon, lilies, incense or saffron. They could bring spices to India thanks to the vast Commercial networks of the Empireand if these perfumes were applied in the human body, they mixed with body smell to work for something … different. Where they were used with more olfactory success it was in the statues, since they sought to enhance that aroma of the gods and goddesses with perfumes that exalted the cult of deities. What is clear is that what for us would be something nauseabundo, for the ancient Romans was everyday, the smell of the home. Do you remember the Maximum sewer? That class difference was also there: while the popular classes had blind wells, some Domus rich did have direct connection with the sewerage system. And now I can’t stop imagining how to smell some lentils reminds me of winter afternoons when I was little … and how for a Roman legionary away from home, smelling a swamp could make him think “as at home, nowhere.” Images | Pinterest (Peter Connolly), Featuredpics In Xataka | While modern concrete cracks within a few decades, the Pantheon of Agrippa has been standing for 2,000 years: myths and realities of Roman concrete

Italy has found a disturbing way to end the tourist of its beaches: privatize them

by

Summer on national beaches as a national concept we would say that it is in Danger of extinction In southern Europe. And not for the desire, but for the cost. If you start noticing a Run Run Among your acquaintances where talking about vacation on the coast seems little less than an urban legend for the exorbitant price, Italy has a message for navigators: they no longer give to hammocks and umbrellas. If touring homeland He was getting so expensive that he came out More profitable the Caribbeannow we have record. A beach banquet. Counted in a report The New York Times that, on the beaches of Apulia, especially in Bari, the time of lunch was always a Collective show Where entire families display tables, tablecloths and trays full of lasagers, rice with mussels, seafood pastes, fried sausages or raw octopus, keeping alive a custom that goes back to the rise of mass tourism in the postwar period. This practice, popularly known as Fagottari (Those who load with food packages), have their roots in the Italian working culture, when the beach holidays were the Unique accessible luxury and the shared banquet represented a community celebration. A tradition in crisis. Going to the beach in Italy has been a deeply rooted cultural ritual for decades, one marked by the custom of rent sun loungers, umbrellas and cabins in the so -called as stabilimenti Balnari They control much of the coast. However, this summer the influx has fallen between 15% and 25% compared to the previous year in private concessions, especially on working days, while on weekends the beaches continue to fill. The difference is also in consumption: those who come spend less on bars and restaurants, a reflection of generalized economic discomfort. The weight of inflation and prices. The most repeated explanation by business associations is the Loss of purchasing power in a context of inflation and increased cost of life. But this assistance crisis is also associated with the SUSTAINED UP of prices on private beaches, which have increased by 17% in four years. For example, the most extreme: rent two sun louges and an umbrella costs no less than 30 euros on the beaches of Lazio and up to 90 euros in fashion places like Gallipoli, in Puglia. The image of private beaches with rows of empty hammocks has become a symbol of disenchantment. The confrontation. There are more. Given that The Times underlined that in recent years, the rise of foreign tourism and the proliferation of the Stabilimenti Balnari They have been restricting the public space, making access and, in some cases, imposing rules that prohibit introducing food. Club owners allege the need to preserve the “decoration” and income of their bars, but neighbors denounce an attack on A basic rightbecause the law recognizes that Beaches are public And it cannot be forbidden to wear food. The conflict has reached political and legal dyes, with headlines that describe an authentic “Picnic Picnic War”, in which lawyers, consumer associations and even politicians They have intervened. The political and cultural debate. The Guardian told that the phenomenon has opened a deeper debate about the concentration of private management on the Italian coasts, which leaves little space to public beaches. Figures known as actor Alessandro Gassmann They have pointed out That the combination of “exaggerated” prices and economic difficulties is pushing the Italians towards the free beaches. Sector defenders claim that prices have not grown as much as they say and that They include services security and lifeguards, but consumer associations denounce that concessions have become A “black hole” For families finance. For the locals, the fact of having to hide or defend their fasteners represents a symbol of alienation and loss of identity. “Apulia is no longer ours”, Some regretremembering how free beaches have been absorbed by luxury resorts today. Citizen rebellion. Outrage has materialized In protests From Sicily to Liguria. In Lavinio, near Anzio, politician Matteo Hallissey (+Europe) was pushed when planting an umbrella to denounce illegal posters of “private beach”. In Mondello (Sicily), demonstrations made the authorities order to remove turniquetes that prevented access to sand. In Metaponto (Basilicata), the Police intervened to confiscate hundreds of sun loungers and umbrellas illegally. In Naples, activists protested against fenced sections In the spy of the monache, while in Marina di Pietrasanta (Toscana) They nailed umbrellas in the sand as a symbolic act of coastal reappropriation. These actions have visible a generalized discomfort: the feeling that the sea, collective heritage, has been usurped for private interests with the complicity of politicians fearful to face a powerful lobby. The lobby strength. The Stabilimenti sector constitutes a Economic framework Family and hereditary in many coastal regions, where businesses are transmitted from parents to children and generate fortunes linked to summer tourism. In locations such as Bacoli, near Naples, summer income can exceed 100,000 daily visitors. The power of this lobby has made successive governments, for two decades, have avoided Impose real limits to the privatization of the beaches. Faced with this inertia, some mayors, such as Josi Della Ragione in Bacoli, have promoted shock measures: decree that at least 50% From the coast it is freely accessible, knock down illegal constructions and remove equipment that blocks the passage. His determination has faced mafia interests and death threats, but symbolizes institutional resistance to the private appropriation of the sea. Mountain displacement. Thus, while private beaches lose customers, tourism is being redirected Towards the mountainwith special intensity In Los Dolomitaswhere some municipalities already alert risk of massification. The trend does not respond only to the economic factor: more and more Italians seek refuge in fresh altitudes to escape stifling summers, intensified by the climatic crisis. This tourist transfer symbolizes a cultural transformation into Italian summer vacations, in which The traditional model Private beach staggers in front of new social, economic and environmental realities. Perhaps for this reason, those shirts are, in words of manythe last thing left in some more and more privatized and … Read more

This is how scientists are working to find all who remain

by

While the axolotl becomes a global icon, a star in laboratories around the world, an exotic pet and Even a character in Minecrafthis only natural home on the planet is about to disappear. The last time an exhaustive census was made, in 2014, scientists They could only find 36 copies in the Xochimilco channelssouth of Mexico City. A decade later, the search has begun again and is a counterreloj race to save this amphibian. The question is if any. In 1998, Xochimilco’s waters They housed 6,000 of these creatures per square kilometer. By 2008 this figure had collapsed to 100. Now, the question asked by the Ecological Restoration Laboratory of the UNAM is If one is still alive in this environment. A search between networks and DNA. Each sunrise, while a magic fog rises from the canals, Basilio Rodríguez, a former fisherman in the area, throws his stroke into the water. He does not look for fish to eat, as their ancestors did, but to the axolot, an animal that he himself remembers as a delicacy: “smooth, soft, juicy, very rich.” But today, the networks go up again and again with the same disappointing capture: tents and tilapias, two invasive species that are, in part, guilty of this story. But traditional fishing is not the only strategy they are following. Great hope is deposited In an innovative technique such as environmental DNA analysis. To carry it out, scientists collect water samples to look for the genetic traces that the axolotes leaves in its path. And it is one of the opportunities they have in their front by not having found any axolotes. An amphibian with regenerative capacity. Ajolote is an extraordinary animal. He is famous for his neotany, that is, the ability to remain in a larval state throughout his life. This eternal youth, linked to their stem cells, gives it a superpower that fascinates science: Regeneration. If you lose a leg, a piece of brain or heart, you are able to regenerate it completely in a matter of hours. A fragile species that goes to the abyss. There are different factors that influence the disappearance of this species. The first of these are the invading species that have invaded their ecosystem. The tents have devoured axolote eggs, while the tilapias are eaten to the young and compete for the food. No less important is the destruction of your home, since Xochimilco’s water has been drastically deteriorated by urbanization, pesticides of agriculture and pollution. Noise and tourism is also something that can be lethal for these amphibians. Being night animals that love silence, the presence of humans in their natural habitat making floating parties makes their ‘happy’ place become an impossible place for them. Famous in the world and absent at home. While its wild population disappears, the axolotes is living an explosion of global popularity. Its regenerative capacity is key in research on aging and cancer. His adorable appearance has made him In a merchandising product: T -shirts, keychains and stuffed animals. But experts warn. Having thousands of Ajolotes in captivity, many of them albinos and modified for research, will not save the species. The key is to restore its habitat, a titanic task that would cost about 30 million euros, according to researcher Luis Zambrano. The rescue plan is already preparing. Given the impossibility of cleaning everything Xochimilco at once, the UNAM team has launched an ingenious plan B: Create Ajolot shelters. The idea is to collaborate with the Chinamperos, the local farmers who cultivate in the artificial islands. The project consists of restoring the chinampas and surrounding them with moats and filters that prevent the passage of tilapia. In these small aquatic coffers, you could introduce seats raised in captivity with a genetic as pure and similar as possible to wild ancestors. They already look for money to carry it out. To finance this new project, the UNAM launched the campaign “Adopt an Axolotl”. In this way, for about 30 euros, anyone could adopt virtually one of the 140 copies that live in the center, give it name and help finance the creation of these shelters. Something that gave them an income of four million pesos. There are many animals in dangers of extinction. In addition to the ajolotes, in Spain this is a problem that is also present, as in the case of the Canary Islands, which is considered as the community with more species in this situation. Those responsible They can be other animalsbut Also humansas in Brazil. Images | Mattias Banguese In Xataka | During World War II, Australia sent an ornitorrinco to Churchill.

Bill Gates was so obsessed with driving a Porsche 959 that he managed to change the laws that prevented him

by

Bill Gates, Microsoft’s co -founder is, in addition to one of the richest men in the worlda passionate about Supercars that Porsche manufactures. So much so that he even had to fight for more than a decade for the US government to change a law that would allow him to drive his Porsche through the streets of Seattle. Thanks to your perseverance, today Millionaires lovers of supercarlike Elon Musk or Larry Ellison, they can have their garages full of limited editing exotic hypercoches and drive them. The story of a Porsche 959 parked in customs Bill Gates is a great passionate about technology and engineering, so in 1987, he commissioned a brand new Porsche 959 that has just been presented. At that time, 959 was one of the most advanced supercarincluding one of the first biturbo engines with total traction and an electronic toe. The six -cylinder and 2.8 -liter engine of 959 delivered 450 horsepower and was able to reach 317 km/h. A prodigy of technology that the young and already millionaire Bill Gates did not resist driving. However, when his Porsche 959 arrived in the United States, he was held at Seattle Customs. The reason: the strict shock test imposed by US laws had not passed, and that prevented him from being able to circulate on public roads. The Porsche 959 was A technological revolution By the end of the 80s, a supercar that Porsche had developed with a huge expenditure that would never recover For direct sale. Due to the high cost that would add to the list of development expenses that they were not going to recover with sales, the German brand refused to perform the shock tests required by the United States. This left the Porsche 959 in anyone’s land and could not legally circulate in the country, and Porsche did not want to adapt it to comply with the regulations. Bill Gates then found an important problem, since his precious Porsche of the only 337 units were manufactured, he was CUSTOMS IN CUSTOMS of Seattle. Bill Gates’s obsession for that particular model led the millionaire to an unpublished situation that forced his brand new car to remain retained in Seattle customs for no less than 13 years. To ensure that he remained there, the millionaire paid throughout that time the $ 28 per day required by the Port Authority for keep the car parked In your deposit, adding a total of more than $ 138,000 for this concept for more than a decade. The Law “Show and Display” Bill Gates’ tenacity was essential to change this situation. Not satisfied with accepting that his car was confiscated in customs, the billionaire gathered the best lawyers and undertook a legal battle against US authorities to ensure that his Porsche 959 could legally circulate. For more than seven years, Gates pressed Washington to change the legislation and allow an exemption For importation and the use of certain rare and collectible cars that are not officially sold in the United States. In this way, the door opened to them US Millionaires and Collectors They can buy these exotic units and limited editions, although they do not meet certain legal traffic demands. Bill Gates’ perseverance was fruit and, in 1999, President Bill Clinton signed the Law “Show and Display” which allows certain historical or technologically relevant vehicles to be imported and driven under special conditions. This law only affects cars with less than 500 manufactured units and special editions, and limited its driving to no more than 2,500 miles per year (about 4,023 kilometers). These limits emphasized the orientation of the law to allow entry to collection pieces and rare units, not to regular use cars. Thanks to this law, the Porsche 959 of Gates was finally able to leave his captivity in the Customs of Seattle and circulate through the streets of the US.

The 14 million empty homes

by

In May 2024, the New York Times launched A report that undressed the situation of the real estate crisis in China. There was no doubt. It was one of the most serious in their recent history and the numbers were devastating: there were four million finished apartments without buyer, and another ten million sold, but still without building. The oversight was a direct consequence of something that had already happened in Japan. A year later, the situation is a bit worse. The Japanese precedent. The comparison between the current Chinese economy and the Japanese of The nineties It was inevitable: both face the consequences of inflated real estate bubbles for erratic fiscal and monetary policies, excessive expectations and an adverse demographic background. Japan lived a boom in housing prices that multiplied by more than two the relationship between cost and rent, sustained by a wave of first -time buyers, tax policies favorable to land and financial deregulation. He mirage of wealth It promoted consumption and employment, but when the population began to age and the number of new buyers was reduced, the real estate values ​​collapsed, dragging the bag and plunging the country into a deflation trap marked by unemployment and falling birth. The Japanese solution. Japan Times remembered That Tokyo’s political response, based on aggressive monetary and fiscal stimuli, misunderstood the root of the problem: it was a Chronic demographicnot of a conjunctural episode. The consequence was to aggravate imbalances, further increase housing, delay marriages and reduce births. With the passage of time, Japan managed to escape from deflation, but was caught in a Long -term inflation circlewith salaries pressured up for work shortage, industrial weakening and loss of competitiveness, all aggravating population contraction and profiling what some call not only “lost decades”, but “lost centuries.” The Chinese challenge. China today faces a panorama even more severe. The accelerated urbanization, the shortage of land imposed by public policies, the fiscal dependence of local governments of land sales and unlimited growth expectations inflated prices until unprecedented levels. At its peak, the real estate sector came to contribute a Fourth part of GDP national and more than a third of public income, while representing near the 70% of family assetsin front of the 50% in Japan In 1990. With price-unworthy ratios more than double than the Japanese and a residential investment that became 1.5 times higher than the Japanese in proportion to GDP, the prick of the bubble has left millions of homes without demand, collapse of construction, chronic overcapacity and a destruction of family wealth equivalent to a whole year of national production. Residential Zone in Shanghai The demographic trap. If Japan suffered the contraction of first -time buyers to from 40 yearsin China the situation is more serious: due to the Single Son Policythe average acquisition of the first home is earlier, towards 28-32 years. That cohort reached its maximum in 2019, just before the burst of the bubble, which means that there will be no second demand such as the one that the Japanese situation in the 2000s partially relieved. In addition, the population over 65 grows at a dizzying pace: what Japan took 28 years, China will reach it in just two decadesuntil 2040. To this is added a very low internal consumption, just one 38% of GDP In 2020, compared to 50% Japanese in 1990, which limits the capacity of domestic demand to cushion the crisis. The Evergrande case. Today, the Chinese real estate market, which for more than two decades was the great engine of economic growth, crosses a descending spiral that has been five years and threatens to chronify. The magnitude of the collapse was revealed with the record losses of Vanke in 2024 and with the Evergrande decision (The most notorious symbol of the boom and subsequent collapse) to retire from the Hong Kong bag after accumulating liabilities by 360,000 million dollars. Evergrande, that at its peak became the largest promoter of the country and the emblem of an expansion based in debt and speculation, He collapsed When Beijing imposed limits on financing in 2020. Its liquidation reflects not only the failure of restructuring attempts, but also the depth of the crisis that drags the rest of the sector. Urbanization, debt and speculation. Bloomberg remembered That Beijing’s problem has its roots in 1998, when the housing market was liberalized in an even mostly rural country. In just two decades, almost 500 million people They moved to the cities, which generated an unprecedented boom in the construction and turned the house into the main asset of Chinese families, until reaching the 80% of its wealth. Between 2000 and 2015 prices are multiplied by sixfed by speculation and a model that allowed promoters to seem homes not yet built to finance their growth. At the same time, local governments became dependent on the sale of land to sustain their budgets, feedback the bubble. At the end of the 2010, the total value of the real estate sector exceeded The 50 billion dollarstwice the United States market. The “three red lines.” In 2020, fearful of a bubble that could destabilize the financial system, the government imposed Hard restrictions: Limits to indebtedness, liquidity demands and brake on the concession of mortgages. These rules, known as The “three red lines”They suffocated promoters who already operated on the limit of their financial capacity. The coup coincided with the Covid-19 pandemic, which paralyzed works and He stopped the demand. In 2021, Evergrande stopped paying his debt, which marked the official start of the crisis. Other giants such as Country Garden and Sunac followed the same path. Since then, Hong Kong courts have ordered the liquidation of several promoters Chinese, included China South City Holdings In August 2024, confirming the structural fragility of a sector built on debt and unreal expectations. Price drop and excess supply. The demand collapsed from 2022, when the economic uncertainty and the loss of jobs eroded the confidence of the buyers. Prices fell strongly, registering … Read more

The highest rocket in the world again crossed the skies after the disaster

by

Starship needs to get out of the bump. After A long streak of explosionsSpacex looks for a clean flight that allane the way to the new rocket generation. Booster 16 and Ship 37 are already stacked on the launch platform for the tenth flight. This will be the Penultimate Mission of Current Design Before moving on to the third generation starship. Date and time of launch. If everything goes as planned, the takeoff will take place this Sunday, August 24, in an afternoon schedule that will allow observing the reentry of the ship over the Indian Ocean in broad daylight. The launch window for the Starship’s tenth flight It opens this Sunday at 18:30 CDT, local time of Starbase, Texas. In other cities: Madrid, Spain (CEST, UTC+2): Monday, August 25 at 01:30 Mexico City, Mexico (CST, UTC – 6): Sunday, August 24 at 5:30 p.m. Buenos Aires, Argentina (Art, UTC-3): Sunday, August 24 at 8:30 p.m. Bogotá, Colombia (COT, UTC-5): Sunday, August 24 at 6:30 p.m. Lima, Peru (Pet, UTC-5): Sunday, August 24 at 6:30 p.m. Santiago, Chile (CLT, UTC-4): Sunday, August 24 at 7:30 p.m. Caracas, Venezuela (Vet, UTC-4): Sunday, August 24 at 7:30 p.m. How to see the live flight. As usual, Spacex will broadcast the launch Through its website and of Your official account in X. The broadcast will begin approximately 30 minutes before takeoff. For the most enthusiastic, YouTube channels like Nasaspaceflight and Everyday Astronaut They will offer live coverage with their own cameras from the vicinity of Starbase. In Spanish, the coverage of Space border, Mission control, Manuel Mazzanti either Spacexstormamong others. A streak that must end. This tenth attempt comes after a few months complicated for Spacex. The company has lost Four consecutive shipsturning each launch into An invaluable data source to improve its design, but also in a reminder of the complexity involved in building the highest and most powerful rocket in the world. Flight 9, which took place on May 27, ended with the loss of both stages. Booster 14, In his second flightdisintegrated during an experimental landing maneuver, subject to an angle of attack that is too aggressive that its structure did not support. Shortly after, Ship 35 reached the scheduled speed to put out its engines, but suffered a leak in the pressurization system that prevented him from completing his goals and condemned it to turn without control. As if that were not enough, the ship that had to star in this tenth flight, the Ship 36, violently exploded at the test base on June 18 during a fuel load. The culprit, according to Spacex, was a secondary nitrogen tank with structural damage that were overlooked. With this history, the pressure on the new prototypes is maximum. A flight full of experiments. Far from being conservative, Spacex has designed an ambitious mission to continue taking the vehicle to the limit and demonstrating that previous failures are solved. The Super Heavy propeller will not be caught by the tower. Instead, it will go to the Gulf of Mexico for controlled amelution while performing complex tests. Booster 16 will repeat the controlled turn that was already tested on flight 9 to save fuel in the return maneuver, after the separation of stages. But this time, it will intentionally deactivate one of the three central landing engines to test whether a backup engine can take over. The test will end with the propeller making a stationary flight on the ocean using only two engines before falling into the water. The ship 37, meanwhile, has the mission of finally fulfilling the objectives that its predecessors did not achieve. He will try for the first time to open your load gate in space to display eight Starlink satellite models. He will tasta again the redempted of a Raptor engine to perform a controlled orbit outlet. And will fly without some thermal tiles to stress vulnerable areas. In addition, it will test new materials for thermal shield, such as metal tiles (one of them with active refrigeration), and a more aggressive reentry profile. The penultimate test before the redesign. This tenth flight is not one more. It is, together with the eleventh, the last opportunity for Spacex to collect data from the current rocket design before making the jump the Starship 3. This new version, which we have already seen components, promises a deep redesign with larger and more robust fins, and a greater structural capacity. A success on flight 10 would be a fundamental moral and technical impulse for the program, demonstrating that the rapid Iteration of Spacex works and that the path to a totally reusable launch system, although full of explosions, continues to advance. Whatever happens, the show is guaranteed. Image | Spacex In Xataka | Spacex has asked Mexico to stop invading its property and returns the starship pieces that fell into the country

three very specific physical exercises

by

Insomnia is much more than a simple night of bad dream. It is a prevalent disorder that affects between 3.9 and 22% of the population And that not only leaves us exhausted, but also increases the probability of having other pathologies. Now, A new and thorough meta -analysis Compare multiple types of exercises for the first time and reveal which are the most effective in improving sleep quality. A disorder that can be medicated. Insomnia has traditionally tried to alleviate with pharmacological treatments such as It is the use of benzodiazepines. Something that in chronic way cannot be used by the multiple risks of suffering from dementia that present. In these cases, other therapies such as The use of high dose melatonin. A hormone that is produced by our own organism naturally, but whose secretion can be affected when doing A change in our schedules or expose ourselves to the blue light. Now the next step is to find the ideal physical exercise to help reconcile sleep. Something where they wanted to influence a study published in BMJ Evidence-Based Medicine. A study based on network meta -analysis. This methodology gives a great robustness to this investigation, since it analyzed the data of 22 random controlled trials with a total of 1,348 participants. The objective is clear: compare the effectiveness of different types of exercise to improve sleep and relieve the insomnia that can be suffered. And the results point to a podium with three clear winners. There are three very effective exercises to be able to sleep. The study concludes that, although the exercise in general is an effective treatment for insomnia, there are three modalities that stand out above the others: Yoga, Tai Chi and walk or run gently (jogging). Yoga is the king of sleep hours. For those whose main problem is sleeping a few hours, yoga seems to be the most powerful solution. According to the data of the sleep newspapers of the study participants, the yoga increased the total sleep time in about 110 minutes. Being able to sleep two more hours can make a big difference between a deficit dream and one enough. In addition, he showed improve sleep efficiency, reduce the time he spent awake after having slept and shorten the latency of sleep (the time we take to sleep once we are in bed). Walking is the remedy for daycare. If insomnia affects you mainly during the day, with fatigue, lack of concentration and bad mood, walking or running softly can be your best ally. Although before we will have to rule out a possible sleep apnea. This activity proved to produce a great reduction in the scores of the Insomnia severity index (ISI), who measures precisely how bad dream impacts daily functioning Tai Chi as quality and constancy champion. This martial art of slow and controlled movements not only improves the general quality of sleep, but also increases the total sleep time, as seen in subjective as objective. Its greatest advantage is that the benefits of Tai Chi persisted during long -term monitoring, demonstrating significant improvements even 1 or 2 years after the intervention. They have a good scientific basis. Beyond what was seen in the results, researchers point to different neurobiological mechanisms that explain why these benefits. In the case, yoga could see an increase in neurotransmitter gaba reducing the hyperactivity of the tonsil and reducing anxiety levels. In the case of Tai Chi, being a rhythmic and slow mind-body practice, the parasympathetic tone increases and reduces physiological hyperactivation. In addition, in the long term it reduces pro-inflammatory cytokines. In the case of walking or running, there is a direct relationship with the increase in energy expenditure, which leads to reduce levels of Cortisol (The so -called stress hormone), elevates melatonin secretion and favors a greater proportion of deep sleep. A practical guide to choose your treatment. These findings are a powerful tool to customize the treatment of insomnia. This way, The recommendation ‘exercise’ falls shortand now we can be much more specific. If the goal is to sleep more hours, the best is yoga, but if you are looking for an improvement in sleep architecture, Tai Chi is the best option. This study reinforces the idea that exercise should be considered a main treatment strategy for insomnia, especially taking into account its low cost, minimum side effects and high accessibility. The study presents a ‘little’ problem. The authors themselves warn that, due to the nature of the interventions, most of the studies analyzed could not be blind (the participants knew what exercise they did), which introduces a possible bias. A lot of research behind the dream. Sleep well It is vital for any human beingand that is why science has always tried to look for The keys to quickly reconcile sleep. And there are also many myths around. For example, Sleeping less than seven hours sometimes is not always negative or for example ‘sleep of a pull’ It is also a great myth of our society. That is why this type of investigations try to give us light on how to better face these night hours.

How to create a podcast from a text to study, investigate or simply listen if you don’t feel like reading

by

Let’s explain How to create an audio from text wearing artificial intelligenceso that you can have a kind of podcast to study or review something when you do not feel like reading. Thus, instead of having to be reading a text, you can simply relax while listening. We are going to start the article with a series of previous tips and recommendations to take into account before putting the task. Then, we will tell you how you can do it with one of the best tools available for it, and we will continue with two ways to do it with assistants of AI as Chatgpt And some other alternative that is also interesting for Generate voice with artificial intelligence. Before starting, things to take into account Before starting to get to work with this, there are some things that you must take into account. First, you must define whether this audio or “podcast” that you want to create is educational, informative or only entertainment. Try too Be clear if you are going to listen to only you or also some other person, in order to polish how well finished it is. A written text does not always sound natural when you listen to it, especially when you have longer and somewhat intricate phrases. That is why it can be recommended that The phrases are short and close languagenot something that makes you heavy listening. In cases where you are going to be able to do it, Decide tone and voice stylechoosing between one more formal or informal. This may depend on the content you want to consume in audio, and also if you are going to listen to only you or other people. It is also recommended that You take care of the audio duration. The recommended duration may vary, because if it is something dense or to study it may be that from 20 minutes begin to get tired, but if it is for leisure or something narrative you should not have problems with longer durations. If it is something dense, try to segment the content well. And finally, Always check the result and do not be afraid to try again If you don’t convince you. Because sometimes the voices of AI may sound unnatural or there may be errors, and that is why it is important to check it even if it is a bit. In the end, The most important part is in the script That you will create to be narrated, and in this it is what you will have to spend most of the effort. Try to be natural, with good scores and well structured. Audios from your notes with notebooklm The first tool you can use is Notebooklm from Google, a service with which you can use artificial intelligence to organize your sources, and even Create an audio summary As if it were a podcast. It is a kind of chatgpt, but in which everything you do will be based on the sources you have added by hand. You can use notebooklm Through its official website or by mobile applications. The official website is Notebooklm.google.comor also in their apps In Google Play For Android and In the App Store For the iPhone. You can use it for free, but its payment version will give you more audio summaries. The first thing you should do with this tool is to create a notebook or work space. Inside, In the left column you can add sourceswhich are the files that the AI ​​will use to obtain the information. They can be text documents, slides, PDF, YouTube videos or links to web pages or online items. Once you have added the sources, Go to the section of Studiowhere the tool will create an audio summary of the content of all files. With this you will create your personal podcast To get information about everything you want. How can you do it with chatgpt and others AI Another option is to use a generative AI such as Chatgpt, COPILOT, Gemini either Deepseek. These tools They do not allow you to create a downloadable audio file although this is something you can do with other third -party tools. What you can do is listen directly to the AI ​​app. What you have to do is Create a summary script of an article. Then, this script can be heard directly in Chatgpt, Gemini or other platform, or take it to another AI that generates a downloadable audio. Let’s explain everything step by step. To start, you have to tell Chat GPT to make you summarize an article or a web page. For that, You must attach it and include the prompt or the instructions to generate your script. The article from which you want the summary can be included by uploading the text file or PDF, or directly putting the website. The prompt that we have used is as follows: “I want to create an audio to listen to a summary of the content of this website. I want you to generate the script to then copy and paste it into a program that passes from text to audio. The script has to be narrative, without structure, you simply have to write it to read it from there. (Link)” As you can see, in the prompt we have reiterated that the text generated by chatgpt It must be natural and should be read directlybecause sometimes if you do not mention it, you can tend to generate a script scheme with things to be filled, and what I want is to generate a text to copy and paste. Here, It is you who decides how and what do you want to make the summarybeing able to be one or several files that you raise or add. Just remember that Everything you upload or vintages will be saved on servers of the company that owns the AI, so be careful in the event that you are adding sensitive data that you … Read more
