Walking cats with belt is in fashion. We have asked an expert in feline behavior and is clear about what he thinks

by

If you have Instagram or Tiktok and you like cats, I bet an arm to which videos have come out of Cats that leave the house tied with strap and harness. Some even go on a trip around the world, explore forests, jump, run and They even swimas if they were dogs. How is it possible? Is it advisable to walk the cat? To solve these and other doubts we have spoken with Paula VanascoFeline therapist and president of the association Rescues Borges Blanques. The phenomenon of adventurous cats It began to popularize in the 2010 on Instagram. One of the first was Vladimirthat traveled with its owners in a motorhome Throughout the United States. Also Skattya Maine Coon who was traveling on a sailboat with its owner, who was completely deaf and leaned on the cat to know when ships approached or sent him messages. A search on Tiktok returns to hundreds of results. “Cat harness”, “Adventure Cat”, “Cat Leash Training” … Today, any of these searches in Tiktok or Instagram returns us hundreds of results. Walking to the cat is fashionablebut it is not easy. If not, many of the reels that appear to us would not be tutorials and advice to accustom the cat. And if there is something that has tried to know is that, unlike dogs, cats They don’t like anything to atten. Understanding the nature of cats Paula is part of the team of Feline therapy And in your day to day Treat cats with behavioral problemssome of them caused precisely by these walks. Its positioning is clear: it is not a good idea to put a belt to a cat. “Cats are hypersensitive animals. For them a harness is stressful, so when you put it on the first time, many are thrown to the ground.” In addition, he adds that “to make it safe, it has to go very tight, which still makes it more annoying for the animal.” You have to understand that the nature of cats differs a lot from the dog. They are territorial animals and They feel safe within their territoryit doesn’t matter if that territory is the countryside or a flat in the city. When they leave their comfort zone, they always do it very little by little: “The cat needs to explore the territory at its rhythm, not that you take it wherever you want.” Instead, walking to a dog is more natural because its nature is to move in herd. They are social animals And security is provided by your pack, so when we walk them they feel safe. Image: Amparo Babyloni, Xataka Surely you have seen cats rubbing against the corners of furniture or other objects. It is the way they have of Create a safe space. When they explore, cats are rubbing at different points where They leave pheromones that serve as olfactory references. “This is how they explore the territory feeling safe. If there is any scare they go back, then they leave again … and so on until they have it controlled.” “When we get the cat out of its territory, it adopts a prey behavior. If there is a strong noise you will try to run and if you are tied, you can’t do it.” Nor should we forget that, although cats are predators of small animals, they are also prey to other larger ones. “When we get the cat out of its territory, it adopts a prey behavior. If there is a strong noise you will try to run and if you are tied, you can’t do it,” says Paula. It is not that the cats we see in the Instagram videos are all stressed, Some enjoy those outings, But according to Paula “they are the exception. They are cats that have learned that their environment is that and also have a very balanced character.” Using them since childhood is key because “cats do not develop fear until they have 5 or 6 months,” but insists that this is not a guarantee that it will enjoy it and should never be forced. What we don’t see on Instagram If it is outside its territory and scares, The cat instinct is running and getting safebut what happens if we have it tied? Two things can happen: “Let the harness escape or attack you.” In This video You can see perfectly how the cat tries to flee and when not getting it, he ends up biting its owner. Is what is known as redirected aggressivenessan episode in which the cat has a very violent response, in this case for a clear cause: try to flee and not be able to. If the cat tries to flee being tied, two things can happen: “That the harness escapes or that attacks you” The other scenario is to get rid of the harness and run away (the most common, because we already know that Cats are liquid). Being in a environment“It has no visual or olfactory references and there are not a few cases of cats that end up being lost.” If it is also in the city, the risk that a car is hit or attack a dog is very high. There are people who opt for Take the cat inside a backpack type carrier and walk it in this way. Here it is much more difficult for the cat to flee, but Paula does not recommend it either: “I had a case of a cat that took him inside a backpack. The cat did not show the stress at the time, but when he got home he became aggressive. They were very frustrated to be locked up.” Another problem is that many people who get their cats abroad do not know how to understand The language of cats. “That a cat is still does not mean that it is calm.” In other words, it is not necessary to go crazy like that of the video so that it is assuming stress.

The pocket of the Autonomous Communities

by

As half the world, Spain is going through a deep housing crisis in which there is only one group escaping its deadly trap, The heirs. In just five years, the average price of the square meter It has triggered more than 40% According to idealist data, and with this the collection of who receives a percentage of each second -hand sale is growing at a frantic rhythm. The great winners. The Autonomous Communities have two key taxes in regards to the sale of second -hand housing. They are the Tax on Patrimonial Transmissions (ITP) and the Tax of Documented Legal Acts (AJD). The first is the greatest, and communities They establish it between 6% and 11% (except the Balearic Islands, which reaches 13%). In a Spain in which they are sold 40,000 homes per month, The confidential It details how the collection of autonomies is shooting in the first five months of the year: they enter 25% more this year than in the same period of 2024. It is also explained with a growth of 20% of the sale in that same period. In absolute numbers, there are 300,000 operations, the highest figure from an indicated date: 2007, the bubble peak. Income at various speeds. The problem of access to housing is unequal throughout Spanish geography. So is the sale number and, therefore, the collection of autonomies. Madrid and Catalonia take just over 40% of the national collection, despite having 30% of the population. In both communities, ITP and AJD total 9.5% of total income. In the Balearic Islands, that figure is triggered at 22%, more than double the average. It is no accident that these three communities have their capitals in the top of the effort rate ranking. The one that grows the most since last year is La Rioja, with 425%, a fact that is explained by a poor figure in 2024. It is followed by Murcia, Asturias, Canary Islands and Cantabria. The ITP problem. The ITP is, in general, a tax that by default is not divided at the time of purchase. That is, you have to pay it TO TOCATEJA, It is often a huge amount that was not counted, after having to contribute a 20% of the value of housing To access a mortgage. The fractionation has requirements that depend on the autonomous community (as well as the Reductions), and it is not approved by default, but the buyers remain to be triggered for what the administration decides according to the figures and the characteristics of each sale. The aid ends up in the pocket of homemade and owners. For 60% of housing purchases, which are made No mortgagemade by investment funds or wealthy people, ITP may not be a problem, but it has a great effect on the figures to which young people have to save, which are The great losers of the crisisand that often continue to depend on Family aidwith devastating data for Spain. At the moment, the aid raised for rent and buy They only have two winners: homemade and owners who inflate even more prices. The autonomous communities go up to that income car while the nominal types remain fixed in full price escalation. There is only one Fast road to get free housing In Spain: be a doctor and want to work in Pinto.

How to move from image to video using artificial intelligence: 14 essential free tools

by

Let’s tell you How to create a video from a photoso that the image you choose is the reference and the starting point of the video. We are going to do it with a series of free applications of artificial intelligence That we are going to recommend, so you can try until we find the one that best suits you. A common denominator in this type of services that we will tell you on the list is that they are really paying, although they offer free versions so you can try them. These free versions usually have several limitations, from the number of videos that you can create to aspects such as resolutions or water marks. We will start with an explanation on how to create the videos with these websites, and then we will tell you the list of services. And as we always say in Xataka Basics, if you think we have left some important service We invite you to say it in the comments section so that all readers can benefit from the knowledge of our xatakers. Runway One of the great tools for Create Artificial Intelligence Video. You will only have to describe what you want with a Promptadding first an initial image that you can modify as you want. This will be the starting image to generate the rest of the video. Unfortunately Your free version is very limited. When you register for free, you are given 125 credits of a single use, and when you finish it, it is over. Therefore, although the quality of the tool is good, its free mode is a temporary demo. Artlist A website with which you can Create videos from images by AI. You have two options, first create an image from text and from there create the video, or upload a photo or image that is used as a reference to create the video from it. You will be able to choose the appearance ratio and define with a prompt what you want. The page It only allows you to generate a free videoin addition to five photographs. If you want more, then you will have to pay. As for the results, they are quite improvable, those of the creation of images too, and the quality of the video will depend on the starting image, and you cannot even download the video if you do not pay. Fotor This service will allow you Turn a photo into a video. You can upload a photo to use it as a reference and create the video from it and, if you want, also a photo like the end of the video. Then, you can choose a style like anime or cartoon so that the video has it. As is normal, the amount of tokens you have in the free account is quite limited, and they are also aspects such as video quality. But the results are fast and not bad. Akool A website with which you are going to Create animations from photographsbeing specialized especially in portraits or characters. You go up the photo and his AI will give him life with natural movements. This website is able to generate videos up to 4K qualities, although in its free version the maximum is 720p. Other limits you are going to find in your free plan is that The videos will have a water brandand that you have a cap of 1.5 minutes. File sizes can be, at most, 150 MB, and the processing is much slower and takes longer to generate the video than payment users. Hailuo This is one of the best services to Create videos with artificial intelligenceeither from a prompt or From a reference image. You will only have to upload the photo or image you want and describe what you want to happen. The great disadvantage is the great limitation that its free plan has.

Mick Jagger refuses to leave a millionaire heritage to her eight children

by

Mick Jagger, the mythical leader of The Rolling Stoneshe has just completed 82 springs and has done so with the same energy he has exhibited every time he went up to the stage since the 60s. Unlike other public figures of advanced age, Jagger does not want to hear about withdrawing or organizing a Ostetosa inheritancebut to continue enjoying life and thinking about how his fortune can serve others. With an estimated wealth of more than 600 million dollars According to the medium Celebrity Net Worthit could be thought that their eight children already have the insured future. However, Jagger surprised to declare in An interview for The Wall Street Journal that has no intention of guaranteeing a luxury life without their own efforts. In their textual words: “The boys do not need 500 million dollars to live well. It is now.” The incombustible Jagger. Mick Jagger is the father of eight children fruit of several relationships. However, that does not prevent the millionaire artist from not contemplating to leave them all his fortune. According to the assets prepared by Celebrity Net WorthJagger’s heritage includes properties in London, New York, a villa on Moustique Island and a castle in the French region of Touraine. One of his last acquisitions was a house of 1.98 million dollars in Lakewood Ranch in Florida. In addition, due to its incombustible creativity, its fortune continues to grow thanks to its artistic activity, such as the 2023 launch of the Hackney Diamonds album. On its 2018 tour, The Rolling Stones won 117 million dollars. It doesn’t seem much compared to The Eras Tour From Taylor Swift, but his Majesty satanics got it with only 14 concerts. Gain his own fortune. The vocalist of the Stones is not the only millionaire artist who does not contemplate selling his musical catalog to leave his heirs a fortune, as he has done Bruce Springsteenwho sold his for 500 million dollars to Sony. Jagger believes that this financial movement is not necessary to ensure his future nor that of his descendants. As you share in the same interview: “Maybe doing something good in the world.” Other big names of international music have also expressed that leaving excessive fortunes to their children could do more bad than good. Sting, for example, said In an interview that their six children cannot depend on their money: “My children must work (…) people make assumptions. They believe they were born with a silver spoon in their mouths, but it is not so.” This current between artists and millionaires seems to have a clear motivation: prevent their children from growing without knowing the value of work and effort. Inherit less, donate more. This phenomenon “antiherences” millionaires not only occurs among artists. The heirs of Bill Gates and Warren Buffett They are very aware that, at best, only They will inherit A small percentage of their parents’ fortune. Buffett has made it very clear on numerous occasions. The last of them, at the last shareholders of Berkshire Hathaway, in which the “Oracle of Omaha” officially hung its investment notebook and He gave up leadership of your company. “I have never wanted to create a dynasty or pursue any plan that extended beyond the children. I know all three well and fully trust them,” said the veteran in reference to the ability to generate their own fortunes of their three children. Donate 99% of its heritage. Warren Buffett, like Bill Gates, follows the lessons they learned from Chuck Feeneya millionaire who made fortune thanks to the Dutty Free, but who died ruined because he had been donating all his fortune to philanthropic causes. That served Gates and Buffet as inspiration to create The Giving Pledgea philanthropic initiative with which the millionaires promised to donate 50% of their wealth. In fact, the commitment of its founders goes a little further and They have committed to donate 99% their fortune, leaving only 1% of their wealth For your heirs. Starting from fortunes of more than 145,300 and 117.4 billion dollars respectively, that 1% is still a good pinch for their heirs. Children and fortunes for all. However, not all millionaires share the philosophy of Gates or Jagger. One of the most peculiar cases is that of Pavel Durov, founder of Telegram, who has declared Recently that it has approximately 100 children, and that plans to distribute its fortune of 13,000 million dollars, ensuring that all their children “will have the same rights.” Durav represents a vision contrary to the majority current among ultra -ups: instead of reducing inheritance or channeling it towards philanthropic causes, he has expressed his explicit desire to ensure that all their children, known or not, can benefit financially from their success. A singular vision within the debate of The new heirs and its legacked billionaires.

Mexico has declared war on a smuggling that is breaking the Chinese market: the “Cocaine del Mar”

by

A little over a year ago, in June 2024a Mexican National Guard team was watching the Tlaquepaque bus station in Jalisco, when something curious happened. Suddenly one of the dogs trained to detect drugs began to sniff two cardboard boxes located in the officia of a messaging company. As they approached, the agents found that it smelled strange, as a “decomposition product”, so they decided to open the packages. Inside there was no coca, nor hashish, nor weapons, but 80 vexigas Fish dehydrated. The fact is that these buches belonged to a very specific species, the Totoaba Macdonaldiand were not any pieces either. As much as they had bad appearance and poured those 80 veils, which together weighed around 18 kilos, they could have sold for 360,000 dollars In the Chinese black market. For something they are known as “Cocaine of the sea”. Totoaqué? Totoaba Macdonaldi. His name may not be familiar to us in this part of the world, but he is well known in his place of origin, in The coasts of Mexico. To be more precise the species is endemic to the Alto Gulf of California and attracts attention for its size. A totoaba can reach the two meters100 kg of weight and 30 years of life. If for something it is (sadly) famous however it is for its swim bladderor buche, the organ that facilitates flotability. Why’s that? Because in certain regions of China it is considered a treasure, a Delicatesen coveted by their alleged Medicinal properties and that quotes stratospheric values in the black market. Among other uses and despite the fact that there are no solid investigations that demonstrate their goodnessin the Asian giant Totoaba buches are used to make soups that supposedly improve articular pains and relieve the discomfort of pregnant. It is so popular in the country that they are even used as an investment, luxury gift or even dowry. And how much does it cost? Quite. It is not easy to specify it because the price of Totoaba’s bladder is closely linked to the Chinese black market, but a quick search arrives on Google to confirm that it is a luxury merchandise. In 2017 the BBC I calculated that the kilo of Buche could easily exceed 8,500 dollars. The same figure contributed recently the Nikkei agency in An article On the vexigas introduced to smuggling in the Asian market. Others go further and talk about $ 20,000 per kilo, 2,200 euros for just 100 grams or even 40,000 euros for the vexigas of the most desired and most desired specimens. There are those who even slide figures still higher. Is it a problem? Yes. The high demand has submitted to the species at such a pressure that the Mexican government has had to take action on the matter. In the 70s prohibited its fishing, in 1991 It was officially declared in danger of extinction and its name has passed, among other documents, to the list of the Convention on International Trade of Endangered Species (CITES). It also appears in the “Red List” of the Union for the Conservation of Nature (IUCN), whose last evaluation is 2020. There is a vulnerable species. And how is it now? In A statement Published at the end of June, the Mexican government recalls that in the twentieth century Totoaba fishing grew “without control to reduce its population and take it to the edge of extinction” and recognizes that the species is still stalked by smuggling. However, there are some signs that invite moderate optimism. Protection measures and especially repopulation work are helping “little by little” to recover the species. A month ago, in fact, the authorities released 40,000 young in Baja California Sur. In total, in that region about 270,000 have already been released. Are there more measures? Yes. Mexican authorities also carry out controls such as the one that allowed to requisition 80 bucho Last year at the Jalisco Bus Station. Not long after the National Guard and the Customs Agency intercepted another 75 pieces In the Customs of Sonoyta, Sonora. Last March the authorities presumed A new ‘blow’ When removing hundreds of meters from Enmalle networks and dozens of copies of Totoaba on the coasts of the Alto Gulf of California. And at the political level? The species is also part of the Mexican political debate. Over the last years the authorities They have been profiling The legal framework that protects the species and in spring a government commission approved A reform package For that same purpose. Your goal? Regulate the tariff codes that would apply to an export, maintaining, ensures digital road map, the veto to the commercialization of buchors. A few weeks ago the Nikkei agency revealed That Mexico has decided to partially raise the veto to the export of the species, although it speaks exclusively of the meat of specimens of fish farm. The measure is accompanied by a stricter monitoring of the merchandise to prevent its smuggling. Cocaine of the sea? Maybe it sounds excessive, but in recent years the totoaba has earned the nickname of “Cocaine of the sea”. And it makes enough sense. Not only for his high pricealso for the consequences of demand in China. The lucrative business of the Totaba fish illegally and its price in Asia has caught the attention of organizations dedicated to drug smuggling. “The posters realized that these Chinese merchants won a lot with the jellyfish, the Totoaba buche, the sea cucumbers, the abult … and these economies began to penetrate to dominate them,” Explain to The country Felbab-Brown, from the Brookings Institute and an organized crime expert. At the beginning of the year the CBC chain revealed A report of the agency and border services of sample how the networks of Chinese organized crime and the Mexican cartels are resorting to the Canadian ports to exchange buffers and precursors of the fentanyl. Are there more factors at stake? The answer is affirming again. There is another involuntary protagonist who … Read more

China already thinks about strategies to neutralize Elon Musk’s Starlink satellites. Your plan: submarines and powerful lasers

by

Chinese scientists have developed strategies to neutralize the Starlink Satellite Network of Elon Musk, which Beijing considers a military threat. According to the medium The Independentamong the proposed measures are furtive submarines equipped with spatial lasers, attack satellites with ionic propellants and sabotage of the supply chain. An analysis of 64 academic articles published in Chinese magazines reveals the concern of the Asian country for Spacex’s spatial domain. Why worries so much Starlink. The constellation of satellites carried out by Elon Musk controls two thirds of all active satellites in the world, with more than 8,000 operational units. Its ability to provide fast and cheap connectivity anywhere on the planet, including remote areas, makes it a strategic tool. Chinese researchers They fear that the United States will use it as a military weapon after checking its effectiveness in Ukraine, where facilitated the communications of the Ukrainian army and the control of combat drones. What China poses. Several Chinese researchers and scientists have proposed multiple approaches To counteract Starlink. Engineers of the Popular Liberation Army suggest creating a fleet of spy satellites that follow those of Musk, collecting signals and using corrosive materials to damage their batteries. Other researchers propose optical telescopes to monitor the network, generation of false objectives through Deepfakes and the use of powerful lasers to burn equipment. They have also identified vulnerabilities in the Spacex supply chain, which has more than 140 main suppliers. They will not only be countermeasted. Beijing is not limited to planning countermeasures: it is building its own alternative. In 2021 the Chinese state company created SATNET To develop Guowang, a military megaconstellation that already has 60 operational satellites of the 13,000 planned. In parallel, The Qianfan companysupported by the Shanghai government, has launched 90 satellites of the planned 15,000 and already competes for contracts in Brazil, Kazakhstan, Malaysia and several African countries. The geopolitical context. The Ukraine War marked a turning point in Starlink’s global perception. The conflict showed that the control of satellite communications can tip the balance. What worries China is that a single man like Musk can also interrupt critical services. The medium raises as an example that time in which the tycoon He denied his coverage For a Ukrainian counterattack in Crimea. This dependence on private actors He has not only alarmed Chinabut also to traditional allies of the United States such as the European Union, which invests billions in Your own Iris2 constellation. What comes now. The overwhelming domain of Starlink in space, which already operates in more than 140 countries and only has dead areas in North Korea, Iran and China, has triggered a undercover space race. While Amazon develops her Project Kuiper With just 78 satellites, China accelerate your programs To reduce Musk’s advantage. Interestingly, one of the papers of Chinese researchers simply had the following title: “Be careful with Starlink”. It is clear that space control will be an advantage for armed conflicts and commercial wars that are being released.

In 2030 he plans to have the most powerful quantum computer that exists

by

China and the US are the countries that are dedicating more resources to the development of Quantum technologies. And also those who are reaching The most relevant achievements. However, there is a country that has officialized its intention to lead in the medium term both in the field of Quantum computing as in the manufacture of semiconductors: Japan. In the middle of last April we tell you that the Riken Center for Quantum Computing and Fujitsu had just announced that they had developed in a joint project A superconductor quantum computer endowed with 256 cubits. A priori may not seem like a great achievement if we are in mind that IBM already has a condora superconductor quantum processor of 1,121 cubits, and also The Heron platform (5k) endowed with error mitigation. And the China Telecom Quantum Group (CTQG) and the Center for Excellence in Quantum Information and Quantum Physics of the Chinese Academy of Sciences have developed The Xiaohong quantum processor of 504 superconductor cubits. However, Japan’s plan in the field of quantum machines does not end up here. And it is that in 2030 it intends to have a quantum computer 25% more powerful that the most capable that IBM will have at that time. 250 logical cubits to make a difference The design and tuning project of this ambitious quantum machine is already underway. And the Riken Center for Quantum Computing, Fujitsu and the National Institute of Advanced Industrial Science in Japan. This quantum computer will use superconductor cubits and a very advanced cooling system, presumably a dilution system similar to the employee by The machine they presented in April. Whatever your best asset, if you finally get to fruition, it will be its 250 logical cubits. Each logical ul Logical cubits represent a way to overcome the difficulty involved in the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical cubit is constructed in an abstract way About several physical or hardware cubitsso that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows to detect and correct the errors that are present in the physical cubits. Until very recently the number of hardware cubits that was necessary to implement a single logical cubit immune to errors was impracticable, but IBM says that he has found the solution To this problem. And presumably Fujitsu and the Riken center too. IBM is going to build The quantum computer ‘Starling’ in a new data center that will be housed in Paughkeepsie, New York (USA). This machine will bring together 200 logical cubits that, in theory, will allow you to execute 100 million quantum operations. IBM says that ‘Starling’ will be ready in 2029but, as I mentioned a few lines above, Fujitsu and Riken intend to have their quantum machine of 250 logical cubits in 2030. If they get it, they are likely to lead in this field. In any case, before that milestone arrives, much earlier, in 2026, they pursue to be ready A 1,000 cubits computer. They will not be 1,000 logical cubits; They will be 1,000 conventional cubits, and, therefore, prone to make mistakes. Even so, if Japan get it, only one step from the US and China will be placed in this field.

The United States and China seem to compete in ia. The reality is that they play completely different sports

by

Everyone talks about the “career of AI” between China and the United States as if it were a competition where one will win and another will lose. But in reality there is no career because everyone is playing a different sport. The United States invested 100,000 million dollars in AI in the first half of 2025, pursuing AGI as a technological religion. His philosophy is clear: spending billions today to control the future tomorrow. Giant proprietary models, infinite parameters, the search for the Holy Grail of the AGI. China, meanwhile, has not allocated amounts equivalent to its technological sector. Its approach is as pragmatic as Chinese culture itself: to capture market now, monetize in applications later. This divergence does not arise from abstract philosophies, but three concrete structural forces: Chips scarcity. The OCTOBER US SANCTIONS 2022 They cut Chinese access to the most powerful NVIDIA chips. The paradoxical result: China was forced to innovate in efficiency. Deepseek He managed to match the performance of GPT-4 spending eighteen times less money. Technological restriction forced an economic advantage that the United States, with all its hardware, cannot easily replicate. Capital scarcity. The Chinese risk capital collapsed after the regulations of 2022. Chinese the startups collect funds only after demonstrating product working and real metric uses. In this context, opening the source code becomes the smartest strategy: free marketing, viral adoption and developer ecosystem without acquisition cost. BAICHUAN AI AND ZHIPU AI They achieved financing from Alibaba and Tencent precisely after publishing their open models and demonstrating traction. The concentration of applications. The average Chinese user uses less than ten apps per month, almost all channeled through Wechat or Alipay. The American is around thirty. This structural difference completely changes the penetration strategy. In China, who conquered those few points of mass distribution conquers the entire market. In the United States, you have to fight in dozens of different fronts. That is why it makes sense that Chinese companies open their models: they need adoption speed in those bottlenecks, do not own defenses. The most revealing case is how Wechat chose Deepseek Above Yuanbao, Tencent’s own. The decision exemplifies well Chinese pragmatic mentality: the functional product triumphs over corporatism. Yuanbao was his own, but Deepseek was better. Wechat needed quality already, not in two years. Twenty Chinese car manufacturers and more than one hundred hospitals have made similar decisions, integrating Deepseek into their systems. Each integration expands the ecosystem and increases change costs. Behind the Chinese strategy there is also an emotional component that should not be underestimated. After decades being labeled Copycats, Opening the source code has become a way of demonstrating real innovative capacity. Publishing the weights of a model is equivalent to saying: “Here is our work, examine it, improve it if they can.” It is national pride turned into business strategy. The United States continues to build the most powerful AI in the Universe. China is already selling functional to half the planet. Sam Altman talks about the AGI As a civilizational destination, Chinese executives apply the proverb “interests cannot be eaten” and seek immediate monetization. Both can win their respective sports, but it would be absurd to ask who is winning the World Cup when one plays football and the other to basketball. The interesting question It is not who will win the race, but what will happen when in five years One has built the perfect AGI and the other controls the AI infrastructure that uses half the planet.

Freezing rice not only saves time and work: for many Tamnb nutritionists

When one makes rice, there are only two options: either you fall short, or kitchens to feed half regiment. In that second case, the usual thing is to save it in a taper for the next day. What everyone knows is that this daily gesture – guard, cooling and reheating rice – can have effects on your health and even help you absorb less calories. But if it’s just reheating it … There is something else. And no, it is not a Tiktok kitchen trick or a fashion without a base: it is pure biochemistry. In a report by El Confidencial, Dr. María Muñoz – specialist in digestive system at the Virgen de la Arrixaca hospital in Murcia – made it clear that the rice of the next day has no magic, but enough science. “Did you know that cooked and then frozen rice can have fewer calories? It is not magic, it is science and has to do with how your body digests starch,” he explained. The secret is on the starch. The key to this transformation is a substance called Resistant starch. When cooking foods rich in starch – such as rice, pasta or potatoes – a process called gelatinization is produced: starch chains are messy and become more accessible to our digestive enzymes. But if that food cools (for example, in the fridge or freezer), those chains are reorganized in a more compact and less digestible way, through a process called retrogradation. The result ends that starch becomes resistant, that is, it is not absorbed as glucose. Instead, it reaches the colon and acts as a prebiotic fiber. Less calories, better digestion. This type of starch – the so -called type 3 – behaves like a fiber: feeds the good bacteria of the intestine and generates beneficial compounds such as short chain fatty acids, including butyrate, essential for intestinal health. According to has pointed out Dr. Muñoz in El Confidencial, that resistant starch “is not digested or absorbed as glucose, but passes to the colon as a fiber, having a prebiotic effect.” In other words, the body absorbs less calories and experiences a more moderate glycemic response. Something especially useful for people with insulin resistance, digestive problems or who seek to control their weight. Science behind. As We have explained in Xatakavarious studies partially support the benefits of resistant starch. From Cleveland Clinic They define it As “a functional fiber that can help improve intestinal microbiota, regulate blood sugar and contribute to the immune system.” Now, not all types of resistant starch act the same. According to a meta -analysis posted in Scientedirectthe most powerful effects are observed in the types present naturally in foods such as green bananas or legumes. Type 3, the reheated rice, also shows benefits, although to a lesser extent. In other words, you can add, but it will not work miracles on its own. But there is a silent bacterium. The rice has its weak point, and it is not the microwave. When it is already cooked, it is especially vulnerable to a little known but quite resistant bacterium: Bacillus cereus. This bacterium can survive the heat of cooking and, if the rice stays too long at room temperature, find the perfect environment to multiply. The problem comes that it is not enough to reheat it: their toxins can continue there, causing poisoning with symptoms such as diarrhea or digestive discomfort. A silent risk that many times goes unnoticed between tuppers and leftovers of the previous night. Dr. Muñoz He has warned In the confidential that a bad conservation can have consequences. And in Xataka He also alerted that the cooling and overheating cycles – precisely those needed to generate resistant starch – are an ideal environment for this bacterium if they are not handled well. The recommendations are clear: cooling the rice in less than an hour, save it in the fridge (or freezer) without exceeding 48 hours if it does not freeze, reheat only once and never leave it several hours at room temperature. One last concern. Rice not only worries how we cook it, but also how it is grown. In an article published in Xatakawe collected the results of a study that launches a disturbing warning: climate change could be increasing arsenic levels in rice. The reason is in the combination of two factors – more carbon dioxide and higher temperatures – that facilitate plants to absorb more arsenic of the soil. If the trend continues, the impact could be noticed around 2050, especially in regions where rice is basic food. Reheating is not magic, but it can help. Finally, reheating rice can help you absorb less calories, but you will not convert a paella dish into a miraculous diet. Science supports it, provided that good conservation practices are followed. What began as a fashion on social networks has ended up opening a broader conversation about microbiota, glucose and eating habits. In the end, it’s not about changing your life for a rice taper. But with a simple gesture you can improve your intestinal health and reduce the caloric load a bit.

Netflix has 15,000 titles but we end up seeing ‘The Office’ by Quinvez. Productivity apps make us the same

We have 15,000 titles in Netflix and we end up seeing ‘The Office‘For the fifth time. We have a complete suite of productivity apps on the mobile and we end up writing the tasks in A whatsapp with ourselves. It is the same psychological mechanism working in two different contexts: when you have too many options, your brain is blocked and returns to the known. The world of productivity has fallen into the same trap as the platforms of streaming. They sell us infinite customization as an advantage when it is actually a ballast: Notion It allows you to create any imaginable system. Obsidian has more than 800 pLugins Todoist It has configurations for each micronecessity of your workflow. It sounds great until you realize that you have been configuring the perfect system and you have not completed a task. There is fascinating investigation into this. Barry Schwartz showed That more options not only make us happier, but they paralyze us. Each configuration decision consumes mental energy that you could be using to do real work. And here comes the paradox: We value less systems that come preconfiguredalthough they work better than those we have customized until death. The solution is contraintuitive: The most restrictive systems are usually more productive. Apple, for example, understood it a long time. It doesn’t let you change almost anything from the iPhone, but that’s why it works. Limitation is not a bugIt is one feature. You strength to act instead of optimizing forever. The secret is to choose intelligent restrictions. Instead of looking for the tool that can do everything, Look for what does the three things you really need well. Let’s look at a specific example: task management. Notion allows you to create relational databases with personalized properties, dynamic filters, multiple views and automation. You can categorize by project, priority, context, required energy, responsible person. You can create control panels that show productivity metrics and progress graphics. It is the dream of any obsessive control. But While you build that perfect system, your real tasks accumulate. You spend more time thinking about how to organize the work than working. And when you finally have your masterpiece configured, it turns out that it is so complex that using it requires more mental effort than doing the tasks by hand. Contrasts this with Things 3. You have three drawers: Inbox, today, and someday. Spot. You can’t create custom fields, you can’t do Dashboards Made, you cannot automate anything complex. It seems limited compared to Notion. But precisely because of that it works: you open the app, you see what to do today, you do it, you call it. Zero cognitive friction. The usual lesson: Productivity is not about having more options, but about eliminating irrelevant decisions. Your mental energy is finite. Every minute you spend configuring is a minute you don’t spend creating. The most elegant systems are not the ones that can do everything, but those that make obvious what to do next.
