Seoul has released a “holographic police” that arises every night in a park. The intention is clear: dissuade crimes

by

A park in Seoul transforms every night into an unexpected stage. From seven in the afternoon, between street lamps and shadows, the figure of a police with impeccable uniform arises. Speak in a firm voice, throw a message and, suddenly, fades in the air. Two minutes later, it reappears to repeat the same scene. It is not a flesh and bone agent, but about Un real size hologram which has become the new attraction and security measure of the neighborhood. The bet began in October 2024 as an experiment of the Jungbu police station and the Seoul City Council. The selected park was not accidental: located next to the popular gastronomic area of ​​Euljiro, it was the usual scenario of incidents linked to alcohol consumption, As the local newspaper The Scoop explains. Police were looking for a way to strengthen security without displaying more personnel in difficult coverage. Thus collaboration with a technology company arose, which designed a system capable of projecting a virtual agent every night to remember that the place was monitored. A HOLOGRAM AGAINST CRIME The device uses a projector that launches the image of a policeman on a real -size acrylic plate. Every night, the hologram appears for a few seconds and repeats again every two minutes. Its presence is not limited to the visual, since in a clear voice it always conveys the same notice, which Remember passersby permanent surveillance of the area: “Hello, we are the Jungbu police station in Seoul. This area has an intelligent CCTV system. This system is in operation so that the police can respond in real time if an incident of violence or other emergency situation occurs. The Jungbu police station will continue working with the district to create a safer community. Thank you.” The first data collected shows that the bet has not gone unnoticed. According to figures from the Jungbu police station, between October 2024 and May 2025, incidents registered in the Park were reduced around 22% compared to the same period of the previous year. The descent was noticed above all in situations of spontaneous origin, such as altercations or discussions linked to alcohol consumption. For the police, this initial effect demonstrates that the hologram has served to cover holes in the usual surveillance. Those responsible for the project insist that the idea was born from a very specific need. Agent Kim Hyun-Don, from the Jungbu police station, He explained in an interview with the South Klab Canal that the park was surrounded by bars and leisure premises and that many neighbors preferred to avoid it at night for fear of meeting drunken people. “We thought that a visible policeman, even if it was virtual, could give security to citizens and at the same time deter those who could cause problems,” he said. For the police, the hologram is a risky experiment, but also an opportunity to innovate in prevention. Not all citizens interpret the hologram in the same way. While some perceive it as a presence that provides security, others believe that the measure will lose efficacy over time. A neighbor interviewed by The Scoop warned that “to really reduce incidents Frequent patrols are needed or a change in the dynamics of the neighborhood. ”In parallel, comments on the Internet oscillated between the joke and surprise: several users described it as a“ police ghost ”, although others celebrated the originality of the experiment. Seoul Metropolitan Police The project, despite its good initial results, is not free of problems. Those responsible admit that technology is sensitive to external factors: on extreme heat or intense cold days, The projector can fail. There are also neighbors who complain that the voice of the hologram is not heard well when there is noise in the street. To this is added a deeper doubt: if at the beginning it impresses and deter, over time it could become part of the landscape and lose its impact. Seoul’s “holographic police” has become a striking experiment within the debate on how to strengthen security in public spaces. Its initial efficacy shows that technology can provide creative solutions, although doubts about their permanence remain open. It remains to be seen if this model will consolidate as a stable tool or if it will remain an anecdote in the urban history of the city.

Toyota is clear what Spain is still hybrid country

by

Sell ​​what touches where it touches. Toyota has a maximum and it is clear that they want to make clear their potential clients who are not willing to make the jump to the electric car without guarantees. While other brands begin to back down, Toyota doesn’t have to do it. The question is whether it will be late when you want to go ahead. At the moment, this is your way. “We will not drive”. “I hope we can establish Toyota’s electricity in the markets where they achieve strong sales. But we will not boost them in those markets where there is no demand.” These have been the words of Andrea Carlucci, Chief of Toyota in Europe, Automobilwoche. In the German medium, Carlucci wanted to make it clear that they hope to sell in each market what the client claims them although he recognizes that he is not being easy with all the possibilities above the table. “Toyota has always prioritized the client. Determine what technology to offer and adjust it to customer demand It is being particularly difficult. “ Toyota’s strategy. Until now, Toyota has made it clear that he will only sell in each market what the market asks. “Even taking into account the regulations, I think Our growth with hybrids has been organic. We are responding to the strong demand for hybrids in Europe, “says Carlucci. His words are a clear reflection of what the company has been warning. Yes, you will sell electric cars, and Your last ads They are a good example of this, but They do not renounce hydrogen For those who expect keep enjoying sound and the sensations of a combustion engine. Of course, in the United States your strategy with this product is not going too well. And in Spain? Spain has been one of those indicated. “The demand for electric is low in countries such as Italy and Spain. It is difficult to predict what the future quota will be like. As mass manufacturers, it is our duty to serve the demand of customers in each individual market in which we are active.” And the data stress that the company’s strategy is being correct in our country. In the accumulated of the yearToyota does not have a single car among the 10 best selling in our country. And yet, it is the brand that sells the most cars by adding 58,734 registration until July. Far from the 50,972 Renault units and much more than 46,550 Volkswagen units. At this time, 41.51% of Spanish registrations are hybrid cars, for 7.76% electric. He Toyota Corolla He leads sales as the best -selling hybrid and three of the four best -selling cars with this technology are from Toyota. Among the plug -in hybrids, only the Toyota C-HR manages to face Byd Seal U.. And the BZ4X He is tracing among the electric (best -selling sixth) after a recent campaign to lower his price. Backing down. While others have made promises to jump into the electric car in pure brand image, Toyota does not have to face the need to back down. In recent months, Mercedes He has had to confirm that he will continue to investigate with combustion engines. Also Audi. AND Opel, the first generalist In saying that all their releases would be electric from 2025 (and completely electric in 2028) has also done the same. Although Toyota has been indicated for not launching more electric cars to the market and it has been ensured that it was “La Nokia del Autos”the truth is that the hug to the electric car in Europe is not being expected and that is why the brands have begun to brake. But you have to comply. Taking into account the mismatch that seems to exist between European regulators and customer demands, it remains to be seen how toyota faces possible fines to which it risks from 2027. It seems clear that in regions such as regions such as regions such as Germany either Belgium They will have a good opportunity to sell their electric ones but we will have to see if it is enough. The European demand is to force the brands to be below 93.6 gr/km of CO2 contemplating the Average emissions from 2025 to 2027. For each gram exceeded, fines of 95 euros per car sold are contemplated. Here, countries like Spain can be a slab too big. The Toyota Corolla with the least powerful engine Approval 100 gr/km of CO2 and a C-HR rises to 105 gr/km of CO2. It must also be taken into account that plug -in hybrids no longer subtract as before In the average emissions because the way to calculate its emissions has been changed. Therefore, Toyota seems to be clear that he will have to scratch his pocket and enter an agreement with other companies to appear before the European Union with an average emissions below the maximum allowed. Tesla looks like one of the great candidates. Photo | Toyota In Xataka | Toyota boast “Kaizen” philosophy and a sickly perfectionism. Tesla and Byd have serious doubts that it is really useful

There are turbulence in the world economy and the great Asian millionaires are clear where to put their money: in Bitcoin

by

The wallets of the great Asian heritage are changing, and do so at a dizzying pace. Far from the caution of previous years, the richest families in Asia or ‘Family Office‘They are adopting cryptocurrencies Not as an eccentricity, but as a fundamental pillar of its investments. Promoted by a bull market, a generalized adoption and, above all, by New favorable regulationsAsian money flows to digital assets, marking a before and after in the perception of the sector. A moment of Bitcoin as never seen before. This renewed Asian interest coincides with a sweet moment for the market: Bitcoin has spray records this month. So much that has overcome The $ 124,000 barrier. Of ‘try’ to be ‘essential’. Until recently, the strategy of wealthy Asian investors was to allocate a small portion of their wealth to cryptocurrencies, almost like an anecdote of their balances. Today, The mentality has taken a 180 -degree turn. The Director of Investments of Digital Revo Family Office It indicates that last year these families or ‘Family Officers’ began to tote the terrain of cryptocurrencies. But it has not been until now when they wanted to have a token directly. This change translates into an unprecedented demand. Heritage managers claim to receive a growing number of consultations, cryptocurrency exchanges They see their negotiation volumes shoot and the specialized funds in cryptoactive are booming, as reported by Reuters. New funds of crypts that triumph. A clear example is that of Nextgen Digital Venture. Its founder, Jason Huang, launched A new crypto-action background In Singapore at the end of May and success was immediate. He points out that they raised “100 million dollars in just a few months.” And the result has been very good, since this first fund closed 2024 with a 375% profitability in just two years. Points to the following: Our investors – mainly family and entrepreneurs of the Internet/Fintech – recognize the growing role of digital assets in diversified portfolios. A trend that goes to the future. Precisely, the Swiss Investment Bank UBS Corroborate this trend To Reuters, pointing out that some family officers of great Chinese fortunes plan to increase their exposure to cryptocurrencies to reach about 5% of their portfolios. Regulation is the key piece that drives trust. Specifically, two recent laws have been very significant. The first one is the Hong Kong Stablecoins Lawwhich was approved in May 2025 and establishes a complete regulatory framework. It forces any stablcoins issuer referenced to the Hong Kong dollar to obtain a license from the Monetary Authority of Hong Kong and to meet strict requirements, such as a disbursed share capital of at least 3.2 million dollars. Something that has given stability and security to investors. The US law genius act Signed by Donald Trump in June also has part of responsibility. And it is that it establishes license and supervision requirements for the emitters of Stablecoins, which requires that they are 100% backed by liquid reserves such as effective or treasure bonds and reinforces consumer protection. Something that has also given a lot of confidence to the market. More sophisticated strategies and bitcoin as refuge. Investors are no longer limited to buying and waiting for results. Some managers such as Lighthouse Canton point out that the most advanced family officers They have begun to adopt neutral market strategiessuch as the ‘Basis Trade’ and arbitration. All to improve their yields. In addition, in a context of macroeconomic uncertainty, Bitcoin is consolidating as a “portfolio diversifier.” Giselle Lai, associate director of investments in digital assets at Fidelity International, explains that investors use it more and more to cover the risks, given their low correlation with traditional shares and bonds. The numbers do not lie. Hashkey Exhange, one of the license platforms in Hong Kong, has seen how their number of customers has shot 85% year -on -year. The same happens in South Korea, where the three main exchanges have registered a 17% growth in their total negotiation volumes so far from 2025 compared to the same 2024 period according to Reuters. Behind cryptocurrencies there are many stories. Apart from being a big business, over the last months we have seen failures such as Terrausd collapse or its prominence in The next East Wars. But there are also many surprises, such as The revaluation of 80,000 bitcoins at 17,000,000% or the Lord that He lost to his misfortune a hard drive With great economic value in Bitcoins.

China was isolated from one of the key arteries of the Internet for an hour. It is not clear if it was an essay or a failure

by

On the Internet there are falls that are noticed. And then there is what happened in China. For a whole hour, one of the main road traffic with the outside stopped working without explanation. It was not a total blackout, but a cut that became visible in many parts: applications that were halfway, websites that did not respond, services that failed right in the border crossing. The ruling did not fit with the typical local fall or with a problem of a single operator. It lasted 74 minutes, crossed networks and left behind an awkward silence. What fell was not all the Internet, but a concrete and widely used part: the channel that allows encrypted connections to function safely. According to GFW Reportbetween 00:34 and 01:48 of August 20, Beijing time (UTC+8), a generalized blockade was recorded in the Port 443which is the one that uses the majority of traffic HTTPS. The effect was broad and sustained, but did not affect other channels. The most striking thing is that, until now, no one has explained what caused that cut or why it happened in that strip. The technical analysis points to a very concrete pattern. Every time a connection tried to settle in that port, special packages – the RST+ACK – appeared that act as a closing order. They are the digital equivalent to hang the phone before someone attends. These packages were not sent by mistake: they were being injected into large quantities just at the key moment of the exchange between client and server. According to the specialists, this alteration did not fit with a fall due to congestion and affected both connections that came out of China and to those trying to enter. Despite the serious cut, not everything stopped working. Internal connections within China were still active, and other ports, such as 80 – for non -encrypted traffic – or 22, intended for remote connections, showed no block signs. The problem was focused on port 443. That explains why some services could continue to work while others became inaccessible: it was not a total disconnection, but a very selective interruption of the encryption step that crosses the digital border of the country. There are no public reports indicating that platforms such as WechatBaidu or Weibo suffered a generalized fall in that strip; Its main infrastructure is mostly within the country and does not depend on the international crossing for basic functions. But many Chinese apps incorporate components that depend on Servers outside of China-action, mini-programs, external APIS or cloud functions-and those calls could fail when the encrypted step was blocked. There are no public reports that indicate that platforms such as Wechat, Baidu or Weibo suffered a general fall in that strip The impact was more noticeable in international services. According to The Registerpart of the connections of foreign services – including some functions of Apple or Tesla – could be interrupted for users in China during the blockade window. Other international services that depend on HTTPS, such as certain CDNS or VPN connections that use TCP/443. In summary: the internal network was not broken, the encrypted channel was cut out and that was enough to leave many out. One of the most relevant clues is precisely that technical footprint. Each system that filters or interrupts connections leaves a trail –a fingerprint– Recognizable for the order of the packages, the TTL or the TCP window size. In this case, these values ​​differ from the previous documents, so the researchers propose two hypotheses: a new equipment deployed for tests or a known team that was in an anomalous or poorly configured state. The conclusions remain in condition until there are more data. Traffic returned to normal and there were no visible consequences on a large scale.But the cut was real, it was documented and left an unknown in the air. There were no officials or official explanations. In any case, the great firewall is still there, functioning as always, and with an intervention capacity that this time was recorded.

The largest Russian nuclear cruise has returned to the sea after 28 years. What is not clear is how modern its technology

by

Russia has returned to the sea to its largest nuclear cruise For the first time since 1997. The Admiral Nakhimov began the trials on August 18, 2025 at the White Sea, the first concrete sign for a program that has been prolonged for decades. According to Tassthe two nuclear reactors were reactivated in early 2025 and the ship moves again by their own means. However, the return of this 28,000 tons ship It raises the background question: To what extent has modernization fulfilled what is announced by Moscow? Its recent history is marked by a sequence of breeding deadlines. Although modernization was raised more than two decades ago, The War Zone pointsthe works did not really begin until 2014. Since then, the dates were postponed: 2018, 2020, 2021, 2023 … The exit to the sea is a tangible advance, but also the end of a stage full of dilated promises that must now translate into real capabilities. What has really modernized and what follows in the air The return occurs in a context where information about the ship does not abound and, as we see, there are many questions. At the moment, says the aforementioned medium, it can be said that the ship has received at least A new radar systemas well as a new main Caño AK-192m. Modernization aspired to place it as the ship with the most vertical pitchers in the world: 174 cells in total, of them 78 for attack missiles (Kalibr, Oniks, Zircon) and 96 for S-300FM air defense. Today, the only unequivocal is the new main cannon; The rest must demonstrate in evidence and, eventually, in official images and documents. His return to service is not only technical, also symbolic. Everything indicates that he will assume the role of flagship of the northern fleet when Complete trials And be accepted by the Navy, in relief of the Pyotr Velikiy, also a nuclear propulsion cruise. The difference? It began to be built in the Soviet era and was thrown in 1996, but has received minor modernizations. In parallel, the aircraft carrier Admiral Kuznetsov Keep on the wire. In statements collected by Reutersthe president of the State Naval Construction Corporation came to affirm that it is most likely to sell or tear it, which would further raise the weight of the cruise on the Russian surface. The admiral Nakhimov still has a lot to prove. That it has navigate again does not imply that modernization is complete or fully operational. The real state of sensors, combat systems, data links and integration with other naval units remains unconfirmed. Beyond the official story, what happens in the sea will say if this return to the activity is a change of cycle or a maneuver without real impact.

Honda is very clear what is your plan to be neutral in emissions

by

The history of Honda’s birth It is very interesting: Soichiro Honda said that Toyota’s rejection to buy his piston led him to found the company that bears his name. 76 years after its foundation, along with almost all its Japanese sisters, the manufacturer has its vehicles between The most reliable in the world. In full transition from combustion engines, Jay Josephthe CEO of Honda Australia, has surprised with his words: “Battery electric cars are not the final objective. Better electric vehicles are a way to achieve carbon neutrality, although not necessarily the only one.” Honda’s plan. According to Joseph, the Japanese firm will not neglect electric cars, which are working to improve components such as “solid state batteries.” However, its objective is “carbon neutrality” in 2050. It admits that to achieve it, the electric are “the most obvious path in the short and medium term”, but they will not focus only on them: “we will develop other technologies that help us achieve it,” he said. The short term of Honda is hybrid. Robert Thorp, another Honda manager, believes that “while drums are gaining market share and generate a lot of media noise, in practice the choice of consumers remains hybrid.” And it gives as an example the growth in the SUVs: “the electric ones remain plans, and those of combustion are in decline, but all the growth is in the hybrids.” He does not believe that it is only because of the options available in the market, but for his belief “that for consumers, behavioral changes are difficult.” Regarding hybrid SUVs, in Spain there are several among the best sellingsuch as the Kia Sportage, the Nissan Qashqai or the Toyota Yaris Cross, next to plug -in hybrids such as the Ford Kuga or the Hyundai Tucson. Other technologies. Jay Joseph explained other areas where they see potential: Hydrogen fuel battery for saving load times. A vision that they also share with Toyota, Hyundai or BMW, but that faces an infrastructure problem, and that at the end of 2024 there were only 1,160 refueling stations worldwide, According to H2Sstations. Why it is important. At a time when the industry has to decide what it wants to be in the next two decades, Honda continues among the brands that More cars sell in the worldand Growing in double digit in markets as profitable as the American. 20% of the market are already electric carsand what they decide to do since their headquarters in Minato is very relevant due to the impact on the plans of the rest. In that sense, already They announced Although they did not retire from the electric market, they did cut their sales forecasts, which came to estimate 30% of the total in 2030. Cuts. As their Australian managers pointed out, which right now the market goes through the hybrid, Honda announced a 30% cut in its investment in electrification and software by 2025. In the background there is also the fact that governments around the world are making deadlines more flexible to comply with goodbye to combustion and emission regulations. So, Electric car skeptics are in luck. But Honda does not forget them, and facing 2040 still maintains a clear plan: Sell only electric and fuel cell. There is still a decade and a half to meet the goal, so they believe there is room for a gradual transition to the electric. Aligned with whom he sells the most (and other manufacturers). Toyota is the largest car manufacturer in the world, and remains convinced that the electric car It won’t be the preferred option. They believe that investing more money in this technology is to “waste it”, because demand does not compensate to increase investments. At the end of 2023, Akio Toyoda, president of Toyota Motor Company assured That “it doesn’t matter what the electric car improves, it will not happen 30%.” The great Japanese manufacturer is convinced, as Honda, that The future is hybridand has interests not to say goodbye to the market where it has been a pioneer and with which it follows reaping records. Renault sees it similarlyand Others like Volvo are reculating. In general, European manufacturers want most lax deadlines About the prohibition of selling combustion cars from 2035. The argument also reminds Honda’s: the electricity is not sold enough, and that is that the own Tesla sold less in 2024 than in 2023.

The food industry is living its highest price drop since 2014. There is a clear suspect: white brands

by

Manufacturers in the food sector are living an interesting phenomenon. They go up Industry prices in general, Upload the CPIgo up What they pay consumers in stores when they buy food and yet The rates That applies the food industry have been in free fall for almost a year. Moreover, the sector is facing its highest price decrease since early 2014. Behind that apparent nonsense there is a clear suspect: the effect of white brands and The fight that is getting rid of supermarkets. We explain ourselves. A percentage: 3.3%. Among the many indicators that periodically publishes the INE there is one that helps us better understand a key link of trade, which connects industry with the chain of distributors that take their merchandise to stores. The so -called Industrial Price Index (IPRI) records the oscillations in the right prices in That “first stage” of “internal market”, when the articles leave the factories and do not yet incorporate other added expenses, such as transport, marketing or VAT. Your approach is different from that of IPCwhich takes into account the prices paid by consumers. The INE calculates the IPRI for large sectors every month and sometimes the indicator leaves us some surprise, as happened in June, when it showed an annual fall of the 3.3% In the food industry. What does that mean? That month food manufacturers decided to reduce their rates. Why is it important? For what that percentage means. What reveals to us is a Price drop In the food industry, an adjustment of the rates with which the products leave the factory. The most curious thing is that this fall is not the dominant tonic in the industrial sector. On the contrary. Even beverage manufacturers saw in June how their industrial prices experienced A 2.7% rise. He IPRI General registered one 0.8% rise and if We go down to detail We observed that the indicator rose in most industrial branches. It only retreated in oil refinement, the chemical, metallurgical sector … and food. The annual IPC rate, which reflects the prices paid by consumers, also It was positive: In June it rose 2.2%. If we talk about the specific IPC of non -alcoholic foods and beverages of the purchase basket, it also grew 2.8%. It matters what … And imports when. If we look back, to the context, we observe two interesting data. The first is that the price index of the food industry has already a few months adjusting down. In June he scored a variation of -3.3%, but in May he had already done -2.7%and in April 2.2%. Actually the indicator has been going back. The second fact that we must take into account is that the food industry I had a decade without registering such a pronounced price drop. To find a major year -on -year drop, you have to go back to February 2014. What is the reason? The million dollar question. In a context of industrial inflationwith energy, a 3.5% And the increasing industrial prices, why do those in the food sector descend? In An article in which he delves into that phenomenon, Javier Romera, from The economisthe remembered yesterday that the reduction of the industry arrives in a context marked by a crucial factor: the rise of white brands and their growing competition In supermarkets. THE GREAT PULSE OF THE SECTOR. The industry price adjustment therefore coincides with a key moment for manufacturers, marked by the pulse with supermarket chains and The growing weight that white marks have (those of the distributor itself, such as Auchan, Hacondado or Seleqtia). All this also after years marked by a deep inflationary crisis that has made the big chains that manage supermarkets try to contain prices. The phenomenon is not new and Manuel Morales, manager of the IFA group, in An interview with The economist: “If they don’t react, brands are dead.” His notice, he remembered, comes in a context in which white brands have a greater weight in the linear of supermarkets. “Already almost 50% add up and will continue to grow because they have increased quality and differentiating prices is increasing,” Morales foreshadowed. With that backdrop, the food industry has begun to Cut your profitability. In the first quarter it stood at 6.81% after falling for the first time since 2022. Does the white mark grow so much? Yeah. Last year Promarca presented A report which shows that in just a five years, between 2018 and 2023, the presence of white -branded goods in supermarkets increased by 13%. The opposite path followed the articles sold with the brand of its manufacturer, which during that same period they retreated 23%. Promarca represents manufacturers and is therefore interested in, but their report provides a valuable track. Promarca estimates that in a five years they have disappeared from the super more than 3,600 Products marketed by manufacturers outside the distribution chains while theirs, those of the white brand, added 1,800 only in the feeding and hygiene sections. The calculation was made after analyzing six large chains. The Statista platform estimates that the market share of the white brands grew between 2005 and 2015, fell for a few years and would rebound again in 2019 until they were in 2024 in about 46%. Other studies consider that their mark on the linear of supermarkets is greater and already exceeds 50%.

Humanoid robots impress at first glance. Sony is clear what reality is: they still do not know how to move well

by

Humanoid robots are generating a lot of expectation for their futuristic component. Right now, Boston Dynamics’s new totally electric atlas It moves in almost aliens, and The humanoids of figure They already learn to handle coffee makers and washing machines. The feeling is that the Robots revolution is just around the corner, but in its design they hide a problem that is slowing its true potential. And the solution does not go through adding more calculation power. The ‘silly’ body of robots. A recent study From Sony’s own robotics division, he points out that the root problem that limits his own machines is the “limited number of joints”, which creates a “disparity between their movements and those of the subjects they imitate.” That in this case are humans. As explained by the director of the Mechanical Intelligence Research Group at the London South Bank University, the current approach to the robotic industry is “the first brain.” Incredibly complex software is designed that has to centralized a body that is, in essence, a metal knead and engines connected by slightly flexible joints. An attempt to resemble the human that fails. If we move as we moveS In day to day, it is not for ‘magic’, but because we are an almost perfect machine that has about 360 joints, 206 bones and numerous ligaments. This makes the column flexible or the joints adapt to any movement. But humanoid robots are simple rigid structures that constantly fight against their own weight and inertia. In order not to fall, they need to perform millions of microcorrections per second, also consuming a lot of energy. According to the data, a Tesla Optimus robot to make a simple walk Consume about 500 wattswhile a human being for a more demanding walk Consume 310 watts. The clumsy that they are is increasingly evident. The famous Optimus video folding a shirt It is, in reality, a demonstration of its great physical weakness. A human can fold the shirt almost without looking, using the touch to feel the key and guide their movements. Optimus with his rigid hands depends on his powerful vision and his brain to meticulously plan every tiny movement. The same goes for Atlasthat although it makes spectacular acrobatics, I could not walk safely on a rock covered in moss because the feet cannot feel the surface to adapt to it. {“Videid”: “X83kba5”, “Autoplay”: True, “Title”: “Tesla Bot: This is the humanoid robot that is creating Elon Musk”, “Tag”: “”, “Duration”: “135”} The solution is already explored: mechanical intelligence. This It is a concept that nature perfected millions of years ago and that researchers around the world are beginning to apply in robotics. The idea is simple: design the physical structure of a machine to perform ‘calculations’ and passively adaptations without the need for a central brain or extra sensors. In nature there are many examples of this. For example, the tendons of a hare act as intelligent docks that absorb the impact by landing and release that energy to boost the next stride. The human hand is also able to passively adapt to any object and the yolks of our fingers conform to moisture to achieve the perfect friction level. The investigation is already demonstrating the value of this approach. For example, there are robots with legs inspired by the tendons of a cheey that can run with notable energy efficiency. In Xataka We do not need necessarily humanoid robots. We need machines that do what we can’t even imagine The efforts are put to increase their presence. Companies are clear that humanoid robots are the future. Some like figure They have already created a system to make large -scale robotsor even China is doing exhibition of your best models To make it clear that they have gone from theory to practice, and even They put them on sale. And such is the number of companies that have been launched towards this market, which It costs to differentiate each other. But they already do very common tasks such as Play football or participate in Kickboxing tournaments between robots. And even work for an hour remembering exactly what their hands ‘feel’.

Many times we have heard that “a glass of wine a day is good for our health.” We have also heard that “the Recommended alcohol amount It is zero”Who is right in this debate? The debates about the benefits and prejudices of a food are not exclusive to fermented drinks such as wine or beer. The relationship between eggs and cholesterol is a classic example but we can also find apparent contradictions regarding the consumption of coffeehe rice or the potatoes. Human health has many dimensions and our nutrition is very varied (even the poorest diets involve the consumption of a wide range of compounds present in the ingredients of the product or in their additions). Studying in detail The effect of each product is difficult precisely for this reason. That is why science often advances slowly, with the succession of seemingly contradictory studies that are actually simply refining the aim. However, the accumulation of these experiments is granting us a better idea of what happens in our body when we consume alcohol, even when this consumption is restricted to “a glass or two” wine. To better understand the debate, we can start asking us, what is good for wine? The idea that wine can be beneficial to our health is mainly based on polyphenolsnon -nutritious substances but with antioxidant capacity. These compounds present in grapes of which the wine is fermented, they can be beneficial to our health. The problem here is that There are non -alcoholic alternatives where these compounds are also present, such as must or grape itself. In part due to these compounds, it is usually attributed to wine Potential benefits About our cardiovascular health. Experts believe that this improvement could be due to the fact that these compounds favor the reduction of blood pressure and reduce cholesterol. Still there is some discrepancy in this regard among the different studies. A drink with risks Cancer is One of the main risks that are associated with excessive alcohol consumption. AND There are several types of cancer which have been associated with this consumption: in addition to the liver, alcohol consumption has been linked to oral cavity cancer, pharynx, larynx, esophagus, colorectal and, in the case of women, with breast cancer. “The response to whether the relationship between alcohol consumption and cancer risk is clearly established is that there is sufficient evidence,” said Marina Pollán, director of the National Epidemiology Center, in statements collected by Science Media Center (SMC) Spain. The risk, of course, “is proportional to the amount of alcohol ingested, being lower for moderate consumption.” But beyond cancer, excessive alcohol consumption has been conventionally linked to the appearance of the Hepatic cirrhosis (which can also lead to cancer). This disease It arises with the formation of “scars” in our liver, and can also be caused by hepatitis. While we link moderate consumption of wine to an improvement in heart health, alcohol consumption can have an opposite effect. This has also been related to the appearance of alcoholic myocardiopathy, arrhythmias and other heart problems. It should not forget the relationship between alcohol consumption and mental health problems such as addiction itself, being able to exacerbate existing problems. Various studies made in recent decades They have pointed out Alcohol as psychoactive substance More harmful In social terms. One of the most outlined studies in this field was carried out in the United Kingdom and Posted in 2010. Posted in The Lancetits results indicated that this was not so much to the damage it generated in the individual (in this sense it was overcome by heroin, the crackand methamphetamine), but for its social cost. However, these risks are generally manifested after consumptions that we consider “excessive”, in contrast to “moderate” consumption that is often promoted. The problem is that, beyond social conventions or recommendations perhaps without excessive scientific foundation, we do not know if there is such a thing as moderate consumption. According to the Monograph Alcohol 2021. Consumption and consequencesof the Spanish Observatory of Drugs and Addictions, this border does not exist, or in the words of the text itself: “There is no level of risk consumption free of risk.” That is why the health authorities speak not of “moderate” consumption but “low risk” consumption. The risk is never zerobut it is possible to keep it low. And how much is considered “low”? According to the report limits of low alcohol risk consumption, this would be two standard drink units (UBE) in men and one in the case of women. These “standard” measures are equivalent to 10 g of alcohol or, in terms of wine, approximately a 100 ml glass. It is not the same to ensure that moderate alcohol consumption is compatible with a healthy life than to say that this moderate consumption is beneficial to health. Nor is it the same to say that wine can generate a specific benefit in our well -being with ensuring that this possible benefit can be greater than the risks involved in this or other alcoholic beverages. As we pointed out at the beginning, alcoholic beverages (like any other food) contain a myriad of compounds, some harmful, other beneficial for their operation. The general consensus is that the damages of compounds such as alcohol are superior to the benefits that others such as polyphenols can provide. In short, a glass of wine a day can hardly kill us, but We must be aware of the risks They are associated with her. As always, a balanced diet and an active life can always help us reduce our risk of suffering certain diseases, perhaps even helping us to compensate for these small excesses that we can incur.

Smart Band 10 may seem more of the same. After a month on the wrist, it is clear why Xiaomi has chosen to repeat

by

There are times when a new model does not seek to break the previous one. There is no leap that, at least with the naked eye, seems decisive. Just a premise: keep doing what was already working, refining details. The Xiaomi Smart Band 10 It moves precisely in that direction. And although that approach makes all the meaning from the point of view of the product, it also raises a dilemma for the user: if you already know everything, Is it worth going through the box? In a new one 24/7 of the Xataka YouTube channelwe have tested this bracelet for 30 real days to discover if Xiaomi’s bet for continuity plays in favor … or begins to fall short. Mario Arroyo He has been testing the Smart Band 10 for a real month, without concessions: training in the park, home exercise, days of work and rest. And when he says that he has tried “in depth,” he does clearly. Because after several days using her, her impression was clear: “I feel it the same as its previous generation, or even the same as the Smart Band 8”The interesting thing is that this statement is not intended to be negative. It is a finding that Xiaomi has refined its formula without great shocks. Enough to recommend it? In the video we analyze that response in more detail. What we liked (and what is not) of the Xiaomi Smart Band 10 There is something that Xiaomi has managed to nail generation after generation: comfort. Mario confirms it after several days of training: the bracelet is so light that it practically disappears. But that physical advantage has a face B. “The screen is small and its format prevents you from seeing the data with comfort”, That is, the Smart Band 10 does not hinder when you train, but it does not help at all if you want to control your real -time progress. It is not an important lack, but a clue to the type of user to which it is directed: someone who wants to register, does not necessarily interact. As a day -to -day device, this smart band meets the essential. Who has had it on the wrist for weeks has been able to control their health clearly: steps, calories, heart rhythm, blood oxygen, sleep. In sports, we find the more than 150 already common ways, and a detail that he wanted to highlight: “A ‘running course’ where you have 10 different ways to start running with different activities. It seemed to me a cool addition, the truth,” he tells us. But there are also elements that have not changed, as he recalls: “We cannot pay with it because we have no NFC, and we don’t have integrated GPS.” One of the clear advantages of this generation is on the battery. The capacity has not changed – 233 mAh – but energy management is. In the first load, using it in moderation, the bracelet endured 18 days without disheveled. In a second attempt, with more training and the always active screen, he resisted 10 days. The data impresses, but the best is what it conveys: “Put the bracelet and forget about loading it. Not having to be aware of the battery of a device, is health … at least for me, ”summarizes our partner. The full load takes only one hour, but the magnetic connector has not improved with respect to previous models. To what extent does this compensate in front of a smartwatch? The answer, after 30 days of use, is in our video. Xiaomi has found a formula that works for it, and this generation confirms it. It does not revolutionize, but it also does not fail in many ways. “After 30 days using the Xiaomi Smart Band 10 the feeling I have is to see a movie that I like very much for the tenth time,” says our partner. A known experience, yes, but also solid. The price, yes, has risen slightly compared to the previous one. In addition, some details have improved … but is enough to justify your purchase against previous generations? There are things that are only appreciated after living with it day by day, and that is just what we try to address in The latest of Xataka YouTube channel.
