The Hubble has just taken the best picture of the interstellar comet. Makes it clear that we were totally wrong about its size

by

When astronomers announced the finding of an third interstellar object In the solar system, the first thing that caught attention was its size. There was talk of a core of up to 20 kilometers in diameter, colossal dimensions that fed all kinds of hypotheses, including that it was an extraterrestrial ship. Now, the most clear image of the kite, obtained by the old Hubble space telescope, has reduced expectations. It is much smaller than it seemed. The detailed new image of 3i/Atlas, Published by NASA Hubble teamhas allowed astronomers to limit the size of the comet with much greater precision. According to an analysis presented to The Astrophysical Journal Lettersthe icy nucleus of this object of another star system has a maximum diameter of 5.6 kilometers, but it could be much smaller, just about 320 meters. This new estimate is between four and 60 times smaller than the initial figures. The reason for the initial confusion is that, even for the Hubble, the code core is invisible. What we see is a brilliant “comma”, a dust and gas -shaped gas envelope that is expelled from the nucleus as the first observations from the earth could not distinguish the small nucleus of the huge halo of dust that surrounds it. It is getting rid of on the one hand. The image of the Hubble space telescope not only corrects the size of the kite, but also reveals important details of its behavior, such as an asymmetric dust ejection. The kite expels most of the material from the side that looks towards the sun, forming a kind of bright fan. This is a typical behavior in the comets of our own solar system: the heat of the sun causes the surface ice (pass from gas solid to gas) with more force on the daytime side of the nucleus. In addition, a very weak dust tail is distinguished in the direction opposite to the sun, formed when solar radiation pressure pushes the finest particles. This structure confirms that 3I/Atlas behaves as A classic cometand not as an anomalous object. According to the study, the kite loses between six and 60 kilograms of dust per second, a rate that, although it seems high, is consistent with that of other comets observed at a distance to the similar sun. Goodbye to speculation. This drastic readjustment in the size and behavior of the comet has important implications. A smaller core, similar to that of the other known interstellar comet, 2i/Borisovit fits much better in the cosmological models than one of 20 kilometers, which helps to explain that we have not yet seen more than three objects of other solar systems in our neighborhood. As for its shape, the brilliant cloud of gas and dust makes it impossible to detect if 3i/Atlas has an elongated shape as 1i/’oumuamuathe first known interstellar object. What we do know is that this traveler, which moves at the incredible speed of 209,000 km/h, will continue to be a priority objective for more modern telescopes, such as James Webb. Each new observation helps us better understand these fascinating cosmic tourists and, as it has been clear, to correct some precipitated hypotheses.

We are carrying the design of protein foods where to eat clear tuna is from males

by

The hallway has changed a lot in recent years. Light -low fat products are a thing of the past, now what is carried are proteins. Not only with yogurts, Proteíca fever It is in many foods and almost everyone has a design clearly oriented to attract the male audience, but perhaps we are going out of hand. All to black. They commented on this Bluesky thread Following the design of the container of the tuna cans to the natural day. Black background, a small detail in blue and high protein very large. It is not the only product with a design from style; yogurts, fresh cheese, paste and even Frozen Noodles (¿? ¿?). Most have containers in which black color predominates and, to a lesser extent, red, with aggressive designs that highlight the amount of protein that the product has. If you had not noticed, you just have to look for “proteins” in any supermarket. Day, Carrefour, Consume, Mercadona… The trend is clear. Products “high in protein” in day supermarkets. Black does not mean more protein. Or at least not many more. The case of day tuna is a good example. In their container they indicate that it is high in protein, specifically 14.3 grams per can, 25 grams per 100 grams of drained product. However, it is enough to compare it with the Normal natural tuna of the same brand To see that it only has 2 more protein. Of course, the price is much higher: 19.20 euros/kilo for the high protein version and 11.67 euros a kilo for normal. The public. Protein -rich products are aimed at those who seek to increase their muscle mass. Traditionally, the male public has been the most interested in strength training and everything around him. However, we have seen that in recent years every time More women began to do strength trainingto the point that Almost half of gym subscriptions are women. Some powdered protein containers. Gym aesthetics. Although gymnasiums are a more balanced terrain as far as gender is concerned, the aesthetics of training related products such as Protein milkshakes It is already entrenched. A lot of black, intense colors, aggressive typefaces and an aesthetic that seems to shout “if you take this, you will get strong.” The food industry has adopted this visual language, first were the energy drinks And now we see how it has spread to all kinds of products. The containers are sexist. We like it or not, It is so. Right now there is an obsession with eating more protein, but we have also lived others such as low -fat products. If protein -rich products are black, Light They are pink and have softer fishes. The reason is clear: traditionally the female audience has been the most concerned with weight loss. We can still find many products like this In the super, but the fashion of proteins seems to have moved them. Influences. We can think that the container does not matter, but the reality is that it is key in the purchase decision. In This study They found that the container influenced the perception of whether a product was healthy or not, even altering its perception of flavor and determining the purchase decision. The participants tended to associate the products that had a female packaging as healthier, while the most masculine were perceived as less healthy. Some containers of cosmetic products for men. Packaging For males. There is another predominantly feminine industry where we can see this trend more clearly even: cosmetics. The men More and more care about their personal care Beyond the shaving and many brands have launched products of products oriented to them where we find dark colored containers such as black or blue. This ‘masculinization’ is also reflected in the name of the products, such as the ‘fuel’ facial of Kiehl’s or the ‘pure carbon’ of l’Oreal to refer to a facial cream. Perhaps the most exaggerated example we have with This makeup for men To which ‘War Paint’ have baptized, because of course, a real man does not make up, he goes to war.

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.

Roig believes that in 2050 we will no longer have kitchens at home because we will buy the food out. Science is not so clear

by

The appointment was designed to boast resultsbut during the presentation of his 2024 memory, Juan Roig, president of Mercadona, launched a prognosis that monopolized almost more holders than the milmillonary turnover of the company. For many of many, the Valencian He predicted That babies who are born in thirty years will not know what it is to have pots or a caster. “I said and kept it: in the middle of the 21st century there will be no kitchens.” The reason? People will feed out of home or base of precooked dishes ‘ready to eat’ like those sold by the Mercadona itself, according to Roig’s particular gastronomic dystopia. A study Recent suggests that the Valencian perhaps rushed in his forecast and that, despite the changes of habits, Spain remains a country full of kitchens. A percentage: 59.1%. What percentage of Spaniards still cooking frequently? And how do they do it? Questions similar to those are what was raised a while ago Elena Sandriof the Catholic University of Valencia (UCV). To resolve them, he conducted a survey with more than 1,500 participants who threw some interesting conclusions, now embodied in An article Posted in the magazine International Journal of Gastronomy and Food Science. Specifically there is a fact that seems to question that the future without kitchens prophesied by Roig is just around the corner: 59.1% Of the Spaniards still cook daily or almost daily. “It is still central”. The study does not stay there. The study reveals that the average time that 59.1% dedicated to the kitchen is around the hour and a half and that there are still a clear differences between sexes: they cook more frequently, apply healthier techniques and show wider gastronomic knowledge. Its score is several points higher than that of men. If we look at the ages, clear differences are also seen: adults cook more. With that data the expert reaches A clear conclusion: “Homemade cuisine is still central to Spanish culture.” His study also reveals the importance of knowledge to favor “healthy culinary practices” or “sociodemographic disparities”, especially among men, people with low educational level, young people and people who live alone. “They tend to resort more to fast food and prepared dishes, often due to the lack of time, skills or knowledge.” Is it the only study? No. Throughout the last years several studies have tried to answer the same question: do we continue to cook the Spaniards? In 2023 FESNAD, the Spanish Federation of Nutrition, Food and Dietary Societies, made A study With a sample of 1,075 and obtained a photograph somewhat different from that of Sandri: according to their calculations, about 46% of the Spaniards continue to turn on their vitros or stoves every day. It is a considerable percentage, although it already crosses the border of the middle of the population. “Our kitchen at home is losing importance, we do not cook daily and cook alone. We do not cook every day for the little time we have and the speed with which we live,” He pointed out The Vice President of Fesnad, Rosaura Leis. Another interesting perspective is contributed by the Kitchen Canal, which also made Your own study with 2,251 interviews with people between 20 and 65 years. What did you find out? That the large majority of the population (around 90%) cooks at least once a week, but only a very poor 20% does so daily. New times, new habits. The previous fact, of course, must be analyzed taking into account another key that slides the Channel Cocina report: almost four out of ten Spaniards (36%) practice Batching Batchingso they dedicate a day to cook much of the food they consume throughout the week. Among young people that practice rises to 41% and if we talk about Madrid, 46% have incorporated it into their lives. The study It also reveals that more than half of the Spaniards eat from Taper at least once a week, especially lunch from Monday to Thursday, and 43% receive them from other people, especially (yes) of their mothers. Is it the only change? Again, the answer is ‘no’. Throughout the last years industry and researchers have been sliding data that reveal that, although Juan Roig’s prognosis may still sound distant, in Spain it is increasingly easy to meet people who feed (timely or of often) without turning on a single stove or take a pan. The Association of Prepared Dishes Manufacturers (ASEFAPRE) estimates that in 2024 the consumption of its products 6.6% shot In homes, overcoming the barrier of 700,000 tons. To be more precise, per capita intake grew 3.8% to touch 17.2 kg per year. Similar reading leaves Another report From the consultant Kantar, who reveals that the purchase of dishes “ready to eat” has shot 48% in a matter of two years in Spanish supermarkets. Moreover, its survey shows that in 20% of cases the client does not even consume them at home. “The interest at this time lies in the search for balance between time, health and culinary pleasure,” summarizes Veronika Kurshudyan, director of the Customer Area of the consultant. “Look for solutions”. Simply, and although Spain still is a country full of kitchens, people already “not only buy food”, warns Kurshudyan. Now demand something else when he goes to supermarkets: “Look for solutions.” From that approach it is better understood than when a few months ago the CIS dedicated himself to asking the Spaniards if they believed that industrial cuisine and the Fast food They were eclipse to home cooking, they meet a striking result: most (mostthree out of four) people responded affirmatively. What is the conclusion? The key I gave it a few days ago Miquel Echarri in THE COMIDIST- THE COUNTRY: Perhaps the prepared food is gaining ground at a good pace and there is already 40.9% of Spaniards who never cook or do it very afternoon in the afternoon (the other reading left by Sandri’s study), but home cooking is far from being a … Read more

Andrew Huberman is determined to make 150 minutes of cardio a week to live more. Science is not so clear

by

It’s 3:52 in the morning and Ashton Hall Start your day: Mouth Tapingcardio on the balcony, statements, ice on the face, banana on the face, all in timed time. His extreme morning routine went viral a couple of months ago with more 99 million views on Tiktok. What started as Skincare with Journaling He has mutated in a culture cult. More and more men adopt millimeter routines with the promise of order, control and success. In that scenario, Andrew Huberman, Stanford neuroscientificpodcast, Guy supplement, Not only is a reference: he is an architect of this new biohackeada masculinity model. Science and Podcast. Huberman’s fame comes for his program Huberman Lab, where he dissects studies on health, sleep, exercise and supplementation, with serious voice, marked body and surgical safety. Talk about protocols, not advice and millions follow it to the letter. What proposes Sounds simple: look at the sun in the morning, train on an empty stomach, dive into cold water, take magnesium, sleep 8 hours and repeat. But it sells it as a high performance science and packages it in a self -control language, constant improvement and masculinity without cracks. But is it reliable? Not everyone is convinced. The researcher Joseph Zundell (Harvard) has pointed out in Times How Huberman draws hasty conclusions from studies with limited evidence. Many of the articles that he quotes – special about supplements or longevity – are based on animal models or are preliminary. However, it makes them “protocols” with appearance of certainty. And we must not forget the conflicts of interest, since it recommends supplements like AG1 (from Athletic Greens), a company that actively collaborates. Although it is presented as an independent disseminator, its content is also part of the well -being business. Even in the most personal field. An article in New York Magazine He collected former partner testimonies that accuse him of manipulative behavior, toxic relationships and contradictions between his mental health discourse and his private life. One more bro? Yes, but with a doctorate. Huberman embodies the university version of the Bro-fitness: sculpted body, extreme control and scientific discourse. It is less explicit testosterone, plus paers reviewed. However, the objective is the same: optimize body and mind, and project success. Its physical presence is not secondary: it is part of the message. And their theories are perfectly aligned with the new online masculinity referents, where to take care of the skin and make cardio coexists with protein smoothies and direct sunlight as if they were dogmas. In his crusade for longevity, He has emphasized what to do 150 minutes from Cardio A week you can lengthen life. That figure appears in several episodes and interviews. But is it really backed by evidence? Science behind. This is where enthusiasm collides with complexity. The data of the “150 minutes” is not invented, but is decontextualized. In the videos he explains that training in zone 2-moderate intensity, without reaching exhaustion-for 150-200 minutes per week improves cardiovascular health, metabolism and brain function. However, a meta -analysis, published in the British Journal of Sports Medicineanalyzed 26 systematic reviews of 199 cohort studies: a total of more than 20 million observations. The general conclusion is clear: higher levels of cardiorespiratory fitness are associated with a significant reduction in the risk of death and cardiovascular diseases. There is no universal magic figure. According to Justin Lang (Cheo Research Institute)the response to exercise varies between individuals according to age, sex, genetic, health and lifestyle. A high -level athlete will need to train much more to improve its aerobic capacity. Someone who starts can benefit with just walking at a light pace three times a week. Besides, As he warns The cardiologist Jayne Morgan (Piedmont Healthcare), the benefits of cardio are not linear or infinite: more exercise does not always equals more health. The threshold depends on the physical condition and other clinical factors. In fact, studies such as The one published in Missouri Medicine They already talked about an inverted j curve: moderate exercise protects, excess can have adverse effects, especially in the heart. In summary: yes, 150 minutes of weekly cardio is a good reference for most healthy adults, but it is not a closed formula to extend life. Science supports regular physical activity as a longevity factor, but with margins, adaptations and without absolute guarantees. The hidden cost of male self -care. Huberman’s message – orders, discipline, physical performance – connects with a silent anxiety growing among many men. Obsesting with diet, body or training is no longer perceived as a problem, but as willpower. But behind certain extreme self -care routines, what sometimes there is is control, guilt or fear of failing. As the journalist Noemí López Trujillo explains in Newtralthis aesthetic pressure is not understood only in image terms, but as an extension of the norms of traditional masculinity: like it without seemingly effeminate, rendering without showing weakness, improving without speaking of beauty. Therefore, many men seek to “maximize” their physique instead of simply taking care of themselves. And that is where phenomena such as looksmaxxingthat disguise emotional discomfort with improvement language, but push it towards isolation, guilt or even radicalization. There is something in your favor. Andrew Huberman has achieved something that few scientists achieve: to become viral. Has brought complex concepts to mainstream and has aroused the interest of millions in the body, the brain and aging. But its way of translating science into protocol has costs. His statements, such as the 150 minutes of cardio to live more, are based … but also many nuances that he rarely explains. And in a world saturated with productivity anxiety, these nuances are essential. Not everything that seems science is. And not everything that improves your health needs a timed routine at 4:00 in the morning.

If the question is how much money you can donate to a child without declaring it to the Treasury, the law makes it clear: none

by

An increasingly widespread trend among millionaires is the Do not leave inheritance To your children. Bill Gates either Warren Buffett There are good examples of this new trend that seeks to convey the heritage of parents to children in alternative ways. However, it is not necessary to go to fortunes so bulky to meet cases of parents who want to convey part of their heritage to their children when they are still young. Patrimonial donations and movable property. According to him Article 618 of the Civil Code“Donation is an act of liberality by which a person has one thing for free in favor of another, that accepts it.” Thus, as defined by the regulations on the Inheritance and Donations Tax, Donating money, goods or any other form of patrimony to children will be considered as a donation by the Tax Agency. That implies that the donation must meet a series of characteristics and pay similar taxes to those that would be paid in case of inheritance without any limit value. Namely: Plusvalía tax, IRPF and Inheritance Tax and Donations. When donating money seems simpler, but Hacienda Vigila. If, as in most cases, the donation consists of an amount of money not very high, temptation is simply giving it to it. But how much money can you give a child without declaring it as a donation? The law does not establish any type of limit that forces donations to declare, so, technically, it would be donation to even give it a euro. However, such and as indicated From lawyers and inheritances, it is not common for the Treasury to pursue the small deliveries of money or gifts of little value. Nevertheless… Finance can request bank information by detecting certain movements due to the regulations of Prevention of capital laundering and terrorism financingso keep it in mind: Income of more than 3,000 euros in cash to review that its origin is justified profits. Income in 500 euros tickets. They are the most monitored tickets by the Treasury because they are used for criminal activities. Entering a large amount of cash in these tickets will sow many suspicions. Recurring income. The entry of a fixed, periodic amount and from the same origin, indicate some type of commercial transaction and the Treasury will show interest in their nature. The small amounts sent to the same account in a short period of time have the same effect Transfers Entities notify the credits of more than 6,000 euros, and transactions of 10,000 euros or more. Whether they are bank transfers and cash movements. How do they pay children’s money to children? Donations, like inheritances, are taxed by the Donation and Succession Tax. Each autonomous community manages this tax under its criteria, so taxation will depend on the Autonomous Community in which the donor has resided in the last five years. Madrid, Basque Country, Murcia, Castilla-La Mancha, Asturias, Balearic Islands, Canary Islands, Galicia, Extremadura, La Rioja and Navarra are exempt from this tax or bonus it to 99.9% for spouses, parents and children. Andalusia bonuses 99% and other communities apply exemptions of up to 400,000 euros. If the donation exceeds that limit, it must be taxed by it. It is not a donation, but I “preside”. If what is intended with donation is to help financially in a complicated stage, there is an alternative to donation: formalize a loan without interest. This assumption is not subject to taxes or expenses and it is only necessary to formalize a private loan contract and the donor will have to submit the settlement of the property transmissions tax at zero cost. However, in that document the deadlines and the way in which the money will be returned, which can be extended both in time as desired, will be specified, which makes it especially interesting for the donation of large sums of money. What if the donation is not declared? If you choose not to declare the donation and hacienda, it detects that money has been received without justifying its origin, it will be interpreted as an unjustified assets. In that case, such and as indicated the OCU, a Taxation of the IRPF to the marginal type that can reach up to 56% of the donated amount, plus the corresponding sanction.

If the question is how to make a team more productive, the answer according to Jeff Bezos is clear: with two pizzas

by

Amazon is one of the world’s largest companies and Jeff Bezosits founder and former CEO, one of the richest people. In a company like Amazon, productivity, Talent management and the synchronization of the equipment is very important and that everything flows in the best possible way a rule as curious as useful and interesting is responsible: that of the two -pizz teams. The “problem” of the scale. As Explain Daniel Slater, World Innovation Culture Director at Amazon Aws, When Amazon began It was structured “to achieve rapid agility and offer constant value to customers.” Amazon was, at that time, an “inventing machine.” That is why hiring and organizational structure were prioritized. The problem is that Amazon, which started as an electronic commerce, climbed. Climbed, and how. When the company was smaller, the teams “were more centralized and closely linked”, but as the firm began to grow this structure resulted in greater slowness and inefficiency. To face it “we radically change our technical architecture to what is known as Microservice architecture“, explains Slater.” We discourage our monolithic architecture in a vast network of unique and independent services “, which allowed to launch news and offers faster. But that’s not all. According to Slater, to maximize the ability to remain close to users and their needs, at the same time that new products and services are launched, Amazon invented a new way of organizing the equipment. Instead of large teams, the firm opted for smaller and agile teams capable of taking advantage of the architecture of microservices. For this, a fairly peculiar rule was used. The teams of two pizzas. The concept is quite simple and is that no team should be so large that more than two pizzas are needed to feed it. Not because A Amazon make a hole in accounting Buy a median of three more ingredients in the nearest Domino’s, but because “the smallest teams minimize the lines of communication and reduce the general expenses of bureaucracy and decision making.” It is assumed that with Two pizzas They can eat about ten people, although that is an opinion that would be willing to fight with nails and teeth. In any case, “the two -pizz teams” is a somewhat searched form to refer to teams of less than ten people. This size “allows two -pizz teams to spend more time focusing on their customers and constantly experiencing and innovating for their benefit,” says Slater. Does the team need three pizzas to eat? Well, then it’s too big | Image: Pexels The advantages of small equipment. As they expose from Amazon, small teams increase “involvement and training” and reduce the known as Ringelmann effect (Individual productivity is reduced as the group becomes larger, and vice versa). Citing the Hackman and Vidmar studyAmazon says that the smallest teams “also increase employee satisfaction” since “in large teams, individual contributions are less recognizable and individual involvement on specific areas becomes more diffuse.” These small teams, say from Amazon, also allow to experience faster and reduce the cost of failure. A TEAM, A PRODUCT. How do you implement these “two -pizzas teams”? Easy: a equipment for each product or service. In the words of Daniel Slater: “Instead of maintaining complex systems or solving problems that cover multiple services, business lines or customer segments, two pizzas equipment focus on a single service or offer, and only on customers that use it. This unique approach favors effectiveness and scalability.” More pizzas. If the team grows, something likely if the needs increase, “we look for ways to divide it into separate equipment of two pizzas that work in a sub -section of the service with a single subprocess.” However, from Amazon they are aware that this structure is not for everyone and has its counterpart. “Two -pizz teams are not perfect, and are not immune to limitations; an example is that with so many autonomous teams, of a single process, which They work quickly To meet the needs of their own clients, there is the risk of duplication and development in silos, “says Slater. It is also necessary to collaborate between teams so that rapid experimentation is effective, as well as for Share errors and learning.

Nvidia says that China has the best open source AI in the world. These praises have a very clear intention

by

Jensen Huang, the co -founder and general director of Nvidia, is in China. At the end of last week He met with Donald Trump with the purpose of defending the interests of his company before an administration that has drastically restricted your business In the country led by Xi Jinping. During the last fiscal year, which expired on January 26, 2025, China represented approximately 13% of total income of Nvidia with a figure of about 17,000 million dollars. In practice, this Asian nation is the third best client of this company only behind the US and Taiwan. The decisions made by Jensen Huang during the last months clearly reflect that he is determined to defend your presence in this market. And he is doing it. A few hours ago he has made a statement during his visit to the International Exhibition of the China Supply Chain, in Beijing, which is worth not overlooking. Jensen Huang does not give stitch without thread “The models of artificial intelligence (AI) Open source of Deepseek, Qwen and Kimi are the best reasoning models in the world today. They are very advanced. ” Huang has pronounced These words during a talk with Wang Jian, the founder of Alibaba Cloud, the AI and cloud computing unit of this gigantic Chinese company. And this statement has not arrived at any time. Whether or not, objectively, the three models mentioned by this Executive are very competitive, as the reports of Demodazzle either Mediumamong others. The really interesting thing is that Jensen Huang has praised these Chinese models at a very delicate time for Nvidia. At a time when You need to strengthen your complicity with Chinese companies to which they have been selling their GPU for several years. Last week Jensen Huang got a promise from Donald Trump: Nvidia can sell again Your H20 GPU To his Chinese clients very soon. The reception that this chip initially received was very good even though its capacities are clearly lower than those of the other proposals for this company. Jensen Huang has praised these Chinese models at a very delicate time for Nvidia. At a time when you need to strengthen your complicity In fact, initially the Department of Commerce allowed its sale in China because this integrated circuit met the restrictions it had imposed. And despite its limitations Their sales grew by 50% quarter to quarter since it arrived in this market in mid -2024. Everything was complicated for Nvidia in the middle of last April. And is that the US Department of Commerce imposed new restrictions To the export of the H20 GPU, which in practice caused this chip to stop reaching the Chinese clients of this company. During the next few weeks this GPU will come back to the facilities of Tencent, Alibaba or Bytedance, among other Chinese companies, but Nvidia will have it more difficult than ever. And is that Huawei, his main Chinese competitor, is being reinforced with great intensity. Only one day after the US Department of Commerce formalized its latest sanctions He presented his GPU Ascend 920a chip for AI that is clearly intended to occupy in the Chinese market the gaps left by the NVIDIA H20 GPU. The GPU Ascend 920 will begin to be manufactured on a large scale during the second half of 2025 using 6 Nm integration technology that have presumably developed side with Huawei elbow and SMIC. The characteristics of this lithographic node have not yet been officially confirmed, but it will probably use the technique known as Multiple patterningwhich is the same one that SMIC is using 7 Nm chips. In addition, the GPU Ascend 920 will reach a 4 TB/s transfer speed for the memory subsystem thanks to the use of HBM3 chips.

Send a clear message to China

He Taipéi Metro It has a vast network of roads, stations and wagons that cover a good part of the bustling metropolitan area of the Taiwanese capital. So far exceptional or that cannot be found in the suburban of other large cities, such as Paris, Madrid or New York. What is much less common is what was lived there on Monday At dawn: instead of passengers loaded with wallets and suitcases, the stations of Taipéi began to arrive military, soldiers and more soldiers armed with anti -tank missiles. The reason: send a message inside and outside the country. Uniforms in the subway. In the Taipéi subway it is usual to see parents with children, people brought from the office, schoolchildren, tourists pulling suitcases or with the camera hanging around the neck … normal in any urban transport network. On Monday at dawn, however, in the city’s cars and stations, it could be seen Something different: Armed military, anti -tank missiles and army commands by displacing ammunition and food from the outskirts of the city. The department of National defense Taiwanés and his Military News Agency They were responsible for disseminating photos in which armed military is seen in the capital’s metro network. In the operation, Precise Business Insidersoldiers of the Military Police and the third command of the Army participated. The maneuvers concentrated on the heart of the Taipéi Transport Network, between the Shandao and Longshan temple stations, a route that passes through the main station. Click on the image to go to Tweet. Why’s that? It is not that the Chinese army progresses towards Taiwan or the island authorities have proof of some new imminent threat. Monday’s military deployment in the Taipéi subway is part of Han Kuangmilitary exercises with which Taiwan intends to be prepared in case of attack by the Chinese Liberation Army (EPL). The maneuvers themselves are not a novelty. The Han Kuang have been held every year for several decades. What is striking this year is its scope and especially the staging. Means like The BBC either Reuters They point out that it is the drill of greater draft and duration made to date, with a deployment significantly greater than last year. Han Kuang will last 10 days (from July 9 to 18), almost double that in 2024, during which the military will display drones, launcher and missiles, including the Himars launch system supplied by the United States. As for the number of mobilized troops, the maneuvers will participate 22,000 reservists50% more than in 2024. To the house door. The Han Kuang of 2025 (and especially the deployment of Monday morning at the Taipéi Metro) stands out for something else: its visibility. And not only for the gallery or Beijing, but towards the civilian population itself. As Point out Financial Timesthe army wanted to bring its “preparations” for a possible Chinese invasion to the doors of citizens. It is no longer about deploying soldiers in ports or fields, but about mobilizing them in the subway stations, in the caps and before the coffee shops where the Taiwanese have breakfast. “If there is ever a war, they will fight right here,” Recognize An old man from Taipéi to the British newspaper. It is about increasing the public awareness of what would mean an attack on the island, better prepare the population and also prove the use of public transport in case of emergency. Monday’s maneuver It also served so that the military learn to operate in the subway if necessary and “use underground facilities to move troops.” “We are learning from Ukraine”. Not all operations have been carried out in the Taipéi subway. Throughout the last days the Taiwanese army has simulated attacks on infrastructure, decentralized operations, drills of “Urban Resilience” and maneuvers areas and naval to defend the coast. On Monday For example, Taiwan lived live a mines placement exercise to demonstrate his ability to respond to a hypothetical amphibious assault of the EPL. The country also wants to try high mobility artillery rocket system (Himars), by Lockheed Martin, in addition to Earth-Aire missiles Sky Sword. “We are learning from the situation in Ukraine in recent years and thinking realistically about what Taiwan could face in a real combat,” Explain To the Reuters agency an official of the Taiwan defense area, who also reveals that one of the priorities is to protect communications. “The commanders should consider the problems that their troops would face.” “It will never succeed”. It is not causality that Taipéi has decided to strengthen Han Kuang right now. China sees Taiwan as A rebel territory And he aspires to reunify it with the continent sooner or later, an objective that has led him to intensify the military pressure around the island in the last five years. In May the US Secretary of Defense assured That Beijing raises “invading” the island in 2027, and warned: “The EPL is trained for it, is rehearsing.” With that complex backdrop, Taipéi seems determined to show (both inside and home) his ability to defense and response. From China you insist on the opposite message to reduce importance. “Taiwan’s attempt to seek independence through force or relying on foreign actors will never succeed,” He came to proclaim MAO NO, spokesman for the Foreign Affairs. The Government has already warned that, “no matter what weapons use”, “Taiwan cannot resist ELP’s back against independence.” Images | Ministry of National Defense, Roc (Taiwan) In Xataka | While China debate about Taiwan, Europe does not waste time.

In Euro NCAP they are clear how Chinese cars are

by

The Chinese cars They have gone from anecdote to something common on European roads. Great manufacturers such as Byd or Saic have own fleets for bring their cars from Chinabut also They are expanding to manufacture on European land. Some brands are opening concessionaires and, although the market grows, there may be a runrun about whether the Chinese car is As sure as the European, Japanese or South Korean. And who is clear about the answer is the agency that gives the security score in Europe. EURO NCAP. Skepticism. My partner Alberto confesses that one of the Questions that make friends and family more When addressing the purchase of a Chinese car it has to do with security. There is still a certain skepticism due to that belief that the ‘cheap made in China’ translates into some quality. With the new policies promoted by the Government of Xi Jinping, in fact, it seeks consolidate the country as a reference in the Technologies of the futureand precisely they have a lot to say in the battery technology or the electric car. Obligations. Beyond that technological leadership, several things must be taken into account. Chinese companies have been forming joint ventures with more consolidated companies. Geely, for example, has an idyll with Renault. SAIC with Volkswagenso both They share technologies and objectives in areas such as the development of the electric car. In addition to this mutual learning, obligations by regulations come into play. Since 2022, The European Union forces that all new cars approved on continental soil must have a Safety elements series such as emergency braking, the fatigue detector, notices on excess speed, lane outlet or rear camera with cross traffic alert, among other measures. And this is also forced Chinese manufacturers. In fact, due to pedestrian danger, The Tesla Cybertruck is neither expected in Europe. Euro ncap is clear. And apart from the regulations, we have an agency as EURO NCAP. This is the person in charge of performing tests to measure active and liabilities security elements and, when there is a maximum score, it is something that manufacturers use as a marketing element. Surely you have often heard that “Five Euro NCAP stars” Well, the funny thing is that, as we read in Reutersthe organism considers that Chinese cars not only have nothing to envy to Westerners, but are superior to certain models. Matthew Avery is Euro Ncap’s Director of Strategic Development and has been blunt about it: “Forget about what you can think about that the Chinese mean lower quality or worse safety performance. The quality of vehicles models of Chinese brands is better than that of others.”
