Spain wants to regulate the legal resale of tickets. The risk: Let the "BOLI BIC A 300 euros"

by

The situation with the resale of entries has become so unsustainable that the government has had to take action on the matter and raise a limitation to prices that tickets can reach. The lack of control has given rise to reappearing the ghost of the black market and without control: what can happen if the legal platforms of resale disappear, would the resale disappear? Everything suggests that no … Sustainable consumption law. That is the name that receives the Draft approved this Tuesday In the Council of Ministers, and that raises an important novelty in the ticket market: it will be prohibited to resell them at a higher price than the original, plus the accumulated variation of the consumer price index (CPI). For example, if an entrance cost 100 euros and the CPI has risen 3% since then, the maximum legal price of resale will be 103 euros. The intention is clear: to stop the bubble of the bursts of inputs, which currently move legally on authorized platforms such as the Fan to Fan of Ticketmaster, Stubhub either Ticketswap. By the clouds. The problem that exists with the purchase and sale of tickets in Spain we have spoken on the occasion of events such as the Bad Bunny concerts of 2026: not only to get ticket was, a few weeks ago, a Mission practically impossiblebut resale It finds no limitations. Thus, almost immediate entries reach exorbitant prices in resale platformsreaching quintupply the original amount. In Xataka If you have an entrance for Bad Bunny, you have a treasure: the megaconciertes are already devouring themselves The problem problem. According to ‘El País‘, this artificially swollen market of resale is aggravated by the use of bots, a practice prohibited by law but very difficult to pursue and demonstrate. From consumption confirm to the newspaper that “the great economic incentives generated by this resale hinder the applicability” of this prohibition. Thus this law is born: if prices shoot, “they would turn this activity in illegal, being able to urge the blocking of the web pages where the infraction and the consequent sanction for the offender were producing.” Black market risk. There is an important risk of increasing the black market for the sale of tickets with this new law. If these legal platforms have sink, part of the unsatisfied demand can move to unregulated channels, where prices would continue to shoot and there would be no guarantees for the buyer. In Spain, without going any further, there was already A parallel black market Before the arrival of this law, especially in highly demanded events. Tickets were sold on social networks, messaging groups or unofficial portals, and those roads could be reactivated if there is demand. Would we see that legendary claim of “I sell Boli Bic for 300 euros and gift entrance of Bad Bunny”, mythical code to place tickets without saying that tickets are being sold? {“Videid”: “x8nqtg8”, “Autoplay”: fals, “Title”: “Taylor Swift: You were Tour – Trailer”, “Tag”: “”, “Duration”: “80”} The European case. In countries such as France or the United Kingdom, situations have been experienced that situations could be repeated in Spain. Since 2012, France has One of the strictest laws in Europe against the unauthorized inputs. The law prohibits the resale of tickets for shows without the consent of the organizer, with fines that can reach 15,000 euros (platforms such as Viagogo They have been sanctioned repeatedly for selling tickets at prices far superior to the officer). Despite this, the black market continues to represent Between 10% and 25% of total salesespecially in large concerts and sporting events. The case of the United Kingdom is more similar to Spain today: the secondary market has platforms such as Stubhub, Viago and Getmein!, Which have often dominated the resale with prices well above the nominal value. There are laws that require transparency in information (for example, show the exact seat and the original price) but, as in Spain, speculation and use of bots to monopolize tickets remain an important problem. In 2024, the United Kingdom reported More than 9,800 cases of fraud Related to ticket resale, with losses that exceeded 9.7 million pounds.

Israel has been bombing the nuclear facilities that build other countries around its surroundings. This is the real risk of collapse

by

On February 28, 2022, just four days after the start of The Russian Invasion of Ukrainethe country’s troops led by Vladimir Putin bombarded the vicinity of The Zaporiyia nuclear power plantlocated in the southeast of the country. Shortly after, during the night of March 3 to 4, the Ukrainian and Russian soldiers They fought together with the buildings of this nuclear installation. This scenario has been repeated several times since then, which has represented at some times a threat to the integrity of the nuclear reactors of this central. Unfortunately, the Ukraine War is not the only war conflict that has endangered one or more nuclear facilities. During the last five decades Israel has repeatedly bombarded Iraq nuclear plants, Syria and Iran with the purpose, according to the Israeli government, to prevent these countries from developing nuclear weapons. This is the same scenario as presumably triggered The last episode of the conflict between Israel and Iran on June 13. However, not all nuclear facilities are the same. Israel and the US argue that the plants of Fordo, Isfahán and Natanz, all in Iran, who have recently bombarded several thousand Uranium centrifugers. These machines contain uranium hexafluoruro (UF₆) inside, a corrosive gas that if it came to filter to the environment could trigger a radiological and chemical emergency, although there would be no nuclear explosion. In any case, in this article we propose to explore what would happen if one missile or other large -capacity projectile impact on the building of a nuclear reactor. Nuclear reactors cannot explode as an atomic bomb Nuclear centrals in operation used by many countries to generate electricity have been designed to offer A very high security level and hold your operation over time. The first protection barrier that nuclear reactors have external threats is the containment enclosure. This concrete structure is watertight and is designed to keep the primary circuit of the environment completely isolated (we will immediately see what this circuit consists of). This framework is designed not to be degraded by dilation, to support the energy of an earthquake, and even to resist very important collisions, such as the impact of an airplane. However, in addition to protecting the nuclear reactor from external aggressions, it is responsible for preventing the radioactive material to be lodged in the primary circuit Remove and get in touch with the atmosphere. Anyway, the first thing that a missile or a pump would have to damage to damage a nuclear reactor is to destroy, or, at least, penetrate the containment enclosure. The containment enclosure is designed to withstand very important collisions, such as the impact of a plane The other element of the installation that has a crucial role in the proper functioning of a nuclear reactor is the cooling circuit. Although, in reality, a nuclear reactor works side by side with three different circuits. The primary circuit consists of the vessel, which is the deposit that contains Fuel bars and the water that must remain in contact with them to absorb their thermal energy; For the heat exchanger, which is a second tank to which the hot water comes from the vessel; and by a pump that facilitates the circulation of water between the vessel and the heat exchanger. The primary circuit must be closed because the water it contains being in direct contact with the fuel bars is contaminated. And therefore, It is radioactive. The heat exchanger acts as a steam generatorso a second circuit is responsible for introducing the cold water inside that when it comes into contact with the hot water of the primary circuit, it enters the boiling. From there the necessary steam proceeds to transfer to the turbine the kinetic energy that will make it possible to obtain electricity thanks to the action of the alternator. Once the fluid crosses the turbine the water vapor cools and condenses inside an additional tank to promote the appearance of water in a liquid state that will be introduced again in the heat exchanger, thus giving rise to a second closed circuit known as secondary circuit. Again a pump is responsible for the water to circulate between the condensation tank and the heat exchanger. So far we have described two different closed circuits, the primary and the secondary, but we have left a loose end. In order for the water vapor of the secondary circuit to be condensed inside the condensation tank it is necessary to introduce in the latter cold water. And to do so it is necessary to resort to a third circuit known as cooling circuit. The water of this last installation comes from the sea or from a river near the nuclear power plant, hence it is necessary to accommodate this type of centrals near one of these two natural resources. The thermal energy exchange that occurs between these circuits allows us to obtain the electrical energy we need, which is the ultimate goal of nuclear power plants, but also seeks to keep the fuel bars housed in the reactor core within its optimal range of working temperature. The most serious scenario implies the fusion of the reactor core If the thermal energy generated by the fuel material of the fuel bars as a result of the sustained fission over time exceeds, for whatever reason, the capacity of the refrigeration systems of transporting that energy and maintaining the core of the reactor within the optimal range of working temperature, the fuel could be degraded. And if this happens, it could happen from the solid state in which it is initially to the semi -solid state, or even a liquid state. This phenomenon is known as the fusion of the nucleus, and can cause a part of the radioactive material to end up coming out of the vessel. This was, in broad strokes and without entering the causes of the accident, which happened In Chernobil reactor 4 In 1986, but There are very important differences between the nuclear power plant that … Read more

There is a risk with AI agents and accumulated errors: that they are a "sneaky phone"

by

In the game of the “sneaky phone” (or broken, or broken) a group of people transmits a message from one to a secret one. What usually happens is that the original message does not have much to do with what the last recipient receives. And the problem we are seeing is that something similar can happen with the promising agents of AI. Accumulated errors. Toby Ord, a researcher at the University of Oxford, recently published A study On AI agents. In it I talked about how these types of systems have the problem of accumulated or compound error. An AI agent chains several stages autonomously to try to solve a problem that we propose – for example, create code for a certain task – but if you make an error in one stage, that error accumulates and becomes more worrying in the next stage, and more in the following, and even more so in the next. The precision of the solution is thus compromised and may not have much (or nothing) to do with the one that would really solve the problem we wanted to solve. AI can program, but not for a long time in a row. What this expert raised was the introduction of the so -called “half -life” of the AI ​​agent, which would help estimate the success rate according to the length of the task that an AI agent wants to solve. For example, an agent with a half -hour life would have a 50% success in two -hour tasks. The message is overwhelming: the longer an AI agent works, the more likely the success rate declines. Benjamin Todd, another expert in AI, I expressed it differently: an AI can schedule for an hour without (barely) errors, but not for 10 hours. They are not real or definitive figures, but express the same problem: AI agents cannot – at least for the moment – function indefinitely, because accumulated errors condemn the success rate. Humans either are saved. But be careful, because Something very similar happens With human performance in prolonged tasks. In the ORB study, it was pointed out how the empirical success rate is falling remarkably: after 15 minutes it is already approximately 75%, after an hour and a half is 50%and after 16 hours of just 20%. We can all make mistakes when performing certain chained tasks, and if we make a mistake in one of them, in the next task of the chain that error condemns all subsequent development even more. Lecun already warned. Yann Lecun, who directs the research efforts of AI in the finish line, has been notaring the problems with the LLMs for a long time. In June 2023 Indian how the autregressive LLMs cannot be factual and avoid toxic responses. He explained that there is a high probability that the token that generates a model takes us outside the correct answers group, and the longer the answer, the more difficult it is correct. {“Videid”: “X8HJ0VY”, “Autoplay”: False, “Title”: “Chatgpt: What you did not know what you could do | tricks”, “Tag”: “”, “Duration”: “790”} That is why is the correction of errors. To avoid the problem, we need to reduce the error rate of AI models. It is something well known In Software Ingenería, where an early code review is always recommended following a “Shift Left” strategy for the software development cycle: the sooner an error is detected, easier and cheaper is to correct it. And just the opposite does not happen if we do not: the cost of correcting an error grows exponentially the later it is detected in the life cycle. Other experts They point to the Reinforcement learning (Reinforcement Learning, RL) could solve the problem, and here Lecun responded that would do it if we had infinite data to polish the behavior of the model, which we do not have. More than agents, multi -agents. In Anthropic They recently demonstrated How there is a way of mitigating even more mistakes (and subsequent accumulated errors): Use multi -legal systems. This is: that multiple agents of AI work in parallel and then confront their results and determine the optimal path or solution. The graph shows the length of the tasks that AI agents can completely complete over the last years. The study reveals that the time that an AI agent can operate to complete tasks with a 50%success rate can be folded every seven months. Or what is the same: agents are improving in a sustained (and notable) way over time. But models and agents do not stop improving (or not?). Todd himself He pointed something important and that allows to be optimistic about that problem. “The error rate of AI models is being reduced by half approximately every five months,” he explained. And at that rate it is possible that AI agents can successfully complete dozens of tasks chained in a year and a half and hundreds in another year and a half later. In The New York Times They did not agree, and recently pointed out that although the models are increasingly powerful, they also “hallucinate” rather than previous generations. The “system card“O3 and O4-MINI precisely points to the fact that there is a real problem with the error rate and” hallucinations “in both models.

A fifth of Apple’s annual benefit is at risk of disappearing overnight

by

Apple had a big week a few days ago with the WWDC 2025. His most important event of the year, with the permission of the presentation of the iPhone, caught him at a critical moment for the turbulence crossed by AI, but resolved with a much more solid presentation than we expected. At 4,500 kilometers from there, a Washington judge deliberated about a decision that could be a drama for the company’s finances. Amit Mehta, the magistrate, He is studying to prohibit the payments that Google makes to Apple for keeping him as a default search engine in Safari. Why is it important. That check amounts to 20,000 million dollars a year and represents 20% of the income of Apple’s ‘services’ division, the second most important. And being a clean income, without operational costs, also represents around 20% of Apple’s annual net profit. The background. Mehta already ruled that Google violates antitrust laws With these agreements, preventing other competitors from accessing the privileged position in Safari. Now consider several measures to correct this, from forcing Google to share data with rivals to force Chrome’s sale as an independent product. Eliminate the agreement with Apple It would be very direct. There is a reading between the lines to the agreement: it is the form that Google has to deter Apple that it throws its own search engine. A direct and large payment that compensates for giving up its vertical integration. In figures: Apple’s services grew from 85,000 to 96,000 million in 2024. Without the agreement with Google, I would suddenly lose a fifth of its annual net benefit. There is no short -term alternative to replace 20,000 million with 100% gross margin. The threat. Precisely that: not finding a substitute that approaches what Google pays. No one monetizes searches in such a massive and efficient way. It seems very unlikely that Microsoft dedicates such a check to boost bing. And the scale is far from Openai’s possibilities, which already loses a lot of money a year to risk an amount that does not have in position yourself as a search engine. Yes, but. A final judicial decision could take years to materialize. The cause, of course, are the appeals. The judge has anticipated that eliminating the agreement would be a last resort if other measures do not work. And Google will also challenge any resolution that arises from the process. Between the lines. For Google, losing the default position in Safari would not be ideal, but financially would win by recovering those 20,000 million annually. Apple, on the other hand, would lose its main growth engine just when you need it most to reduce its dependence on the iPhone. The following if you reach a stage like this would be a very likely Apple’s own search engine with which to try to create a 20,000 million business a year … or as close as possible.

Putting the International Space Station at risk

by

The sudden open war Between Elon Musk and Donald Trump He has just jump to space with threats in both directions that could suppose the anticipated end of the International Space Station. Trump gave the first blow. After investing 277 million dollars in the presidential campaign of Donald Trump, Elon Musk He left his role in front of Doge With a seemingly friendly farewell broadcast live from the White House. The next day, the president of the United States withdrew the nomination of Jared Isaacman as NASA administrator. Isaacman, an old Spacex partner, had been recommended by Musk to lead NASA. The nomination was made public six months ago. Everything was ready for the businessman to assume the highest position in the space agency, but Trump has commented that he withdrew his nomination to discover that Isaacman was a Democrat. Isaacman, meanwhile, clarified that the government I had always known of his donations passed to the opposite party. Battle of Gallos. If something has in common Elon Musk and Donald Trump is his immeasurable thirst for attention. Although his relationship was already broken, he climbed after Musk described the megaproject of the law ‘One Big Beautiful Bill’ of the Trump administration as a “disgusting abomination”. According to the tycoon, the law increases public debt instead of reducing it. This triggered several stabs that happened on Thursday in a matter of hours. Some as aggressive as an elon tweet suggesting that Trump has not published Epstein’s papers because he comes out in them. But the main cross of accusations and threats has been the following: Trump: “Elon was becoming a heavy one, I asked him to leave, I removed the EV mandate (the Biden order that forces more than half of the vehicles sold in 2032 to be electric) and even if I knew from the beginning that he was going to remove it, he went crazy!” Elon: “Without me, Trump would have lost the elections, the Democrats would control the House of Representatives and the Republicans would have 51-49 in the Senate. What ingratitude.” Trump: “The easiest way to save money from our budget, billions of dollars, is to end Elon’s subsidies and government contracts. I was always surprised that Biden did not do it!” Elon: “Before the president’s statement about the cancellation of my government contracts, Spacex will begin to dismantle the Dragon spacecraft immediately.” The end of the ISS? Although SpaceX’s main business Be the Starlink Satellite Internet servicethe cancellation of all its public contracts would affect multiple government, military and NASA programs, including the resupply and transport flights of astronauts to the International Space Station. With the Boeing Starliner capsule In an indeterminate limbothe Crew Dragon of Spacex is the only ship available in the United States for crew rotations in the ISS. To top it off, NASA committed to its international partners to keep the space station operational until 2030. For all this, Trump’s threat seems impossible to materialize. Nevertheless. If by Musk it were. Elon Musk answered the threat of running out of public contracts with an even worse threat: the immediate dismantling of the Dragon program. It would look like a heated without much route, if it weren’t because it coincides with The wishes that the businessman had expressed Previously: advance the end of the ISS and focus on the conquest of Mars. It is not completely impossible to happen (Musk has been very clear in the past on Starship and Mars as company priorities), But dismantling the Dragon would be a headache, in addition to NASA, for all types of Spacex partners: ESA, the Japanese space agency, the Canadian space agency, Axiom, the companies that had them for their commercial stations, and a long etc. To top it off, NASA had commissioned Spacex the development of the spacecraft that will be in charge of exorbiting the ISS After 2030. If there is a public contract that should not be canceled now is that. Leave a 455 tons space station to your fate and the size of a football field does not suit anyone.

The US will revoke the visa of Chinese students to protect their AI industry. The risk is that he ends up wounding her death

by

China is by far the largest world graduate producer in Stem races (Science, Technology, Engineering and Mathematics), both in absolute and relative terms to the global total. The phenomenon is an exceptional magnitude, but there is a country that has just been slaughtered in their noses: United States. What happened. As they pointed out In The New York Times A few days ago, the US Secretary of State, Marco Rubio, advertisement that the Trump administration “would aggressively revoke” the visas of Chinese students. In these visa cancellations, those students with ties to the Chinese Communist Party (PCC) or those who study “critical fields” that did not define clearly but probably include that of AI will be included. Source: The New York Times. Impact. In 2024 in the United States, 20% of the visas granted to students went to young Chinese students. The measure is worrying for American universities, which depend on international students who pay the full cost – without scholarships – for their annual income. In addition, this decision affects both students who want to ask for a visa from now on and those who are already studying in the country. In total there are about 275,000 Chinese students in all types of university careers. Uncertainty. It is not clear what criteria will be followed to revoke these visas and not as quickly these measures will begin. Nor is it known if China will retaliate, although the number of US students in China is much less significant. In 2020 USA He already expelled to 1,000 Chinese students with ties with Chinese military schools. A massive practice. A report Published by the State Department and the NGO called the Institute of International Education indicated last year that China was the second country with the highest share of international students: only India “exports” more students. In the 2023-2024 COURSE, it received 1.1 million international students, of which 331,000 came from India (23% more than the previous year) and 277,000 from China (4% less than the previous year). Source: CSET. China is absolute power in Stem. If there is a “graduate” graduate producer “(science, technology, engineering and mathematics), that is China. Collected data By cset They reveal that in 2020 China led the number of graduates in these disciplines, with a total of 3.57 million students. Only India approaches with 2.55 million students, but for example in the US the figure is four times lower than in China: 820,000 graduates. Source: CSET. And the one that is most dedicated to these disciplines. Not only is it that China has the greatest number of Stem graduates in the world: it is that the percentage of students who choose these disciplines is also the largest in the world. 41% of students are launched to Stem Carreras. They are followed by Russia (37%), Germany (36%, Iran (33%) and India (30%). In the US, only 20%of students bet on scientific careers. Source: Macro Polo / Paulsen Institute. And that includes AI. In People’s Daily They pointed out A few days ago how approximately 50% of the main researchers of AI are trained in Chinese universities. The worrying thing for the US is not that: they depend a lot on them. A report of the Paulgo Institute of Chicago (USA) recently revealed that 38% of AI experts that develop their professional career in the US They have formed in Chinese universities. They are in fact more than those who have a strictly American origin (37%). China does not stop betting on Stem Education. Between 2012 and 2022 the budget spending of the Chinese government in education increased from 2.2 billion yuan (268,167 million euros) to 4.85 billion yuan (591,187 million euros), more than double. Several Chinese elite universities They have announced His intention to expand his curricula with the objective of prioritizing the strategic needs of the country, and here the AI ​​- who You start teaching in schools– It’s key. Imminent danger. This domain has a direct impact on the capacity of innovation, technological development and industrial competitiveness of China, but also of the countries that allow Chinese students to study and then work in international companies. Cut your wings to that talent is to cut them to innovation. The US will get just the opposite of what it intended. The analyst Alberto Romero explained How these measures are probably designed to protect national security – which Chinese students do not end up “spying” for China. “However, instead of helping the US to enhance their industry, what can happen is that they weaken it. Not only that: that revocation of visas can precisely help China meet their strategic objectives. Nvidia already notified with the hardware. The US opted to veto the export of its advanced chips from AI to China. The shot has come absolutely for the cylinder headand instead of preventing Chinese development and innovation, it has put a rocket. They do not seem to have learned the lesson, and revoke the visas to Chinese students can end up being an even bigger shot that comes out of an even bigger cylinder head.

The Council of Ministers has given green light to a key reform that will allow those who work in professions cataloged as especially dangerous or painful retire before usual. The Minister of Inclusion, Social Security and Migrations, Elma Saiz, stressed that this reform “brings us closer to policies approved by European environmental countries, such as France, Austria or Italy, but above all it is a step forward in social justice.” The objective is clear: to offer an exit from the worthy work world to those who exercise Professions with high accident rates and occupational diseases such as firefighters, miners, height workers, police or flight personnel. Retirees at 52 years. The government has A procedure approved to establish reducing coefficients that allow anticipating retirement age for those who perform activities considered “exceptionally painful, toxic, dangerous or unhealthy” and present “high rates of morbidity or mortality.” Thus, the approval of early retirement applications is extended to unions that until now were not included in the professions list painful and high risk. Among the objective criteria to identify these professions include exposure to noise, permanent use of physical strength, contact with chemical or biological agents and the high probability of suffering work accidents. However, the Royal approved decree It does not specify what professions affect, delegating to social security, employers and unions the task of specifying the specific casuistry of each guild. Requirements to retire in advance. To access this early retirement, maintaining 100% of the retirement pension, workers must prove that they have performed these activities for a minimum time of 15 years and exercise it at the time of requesting the early retirement. The minimum retirement age, even applying these coefficients, may not be less than 52 years, and it will not be possible Active retirement in the same work activity that gave access to retirement. Retirement for other employees. The Law 27/2011 It establishes the terms of the progressive increase in the retirement age in Spain and the quotation time. In 2025, the Ordinary retirement age in Spain It is 66 years and 6 months for those who have quoted less than 38 years, while those who have contributed 38 years and three months can request ordinary retirement at age 65. With the new measure approved by the Government, those who request to retire at age 52 will be computed the remaining years up to 65 years as quoted, so that they are not applied reducing percentages to their pension. Voluntary early retirement. For those who wish to retire in advance without belonging to the recognized risk groups, the law contemplates a significant reduction in the pension. In 2025, the penalty can reach up to 21% of the pension amount if the permitted retirement is advanced, which is 24 months before the ordinary age. That is, a minimum age of 63 years is established to request it. This penalty applies progressively and depends both on the advance time and the quoted years. Social security calculates the cut by applying reducing coefficients for each quarter or month of advance with respect to the legal retirement age. This measure aims to discourage early retirement generalized and guarantee the viability of the public pension system.

We have discovered a relationship between olive oil and risk of death by dementia, a point in favor of the Mediterranean diet

by

Someone could think that everything is already said, all investigated, on one of the fundamental axes of the Mediterranean diet, olive oil. Nothing is further from reality: research on this food continues and continues to reveal striking aspects of the liquid. And as regards striking relationships, perhaps the palm is taken by the fact that they keep the consumption of this derivative of the olive and dementia. 28%. A study published a few months ago established existence of this relationship. Specifically, the analysis responsible for the analysis observed a 28% reduction in the risk of death associated with dementia between people who consumed at least Seven grams of olive oil per day, compared to those who did not consume this liquid or did it rarely. Until now, some studies They had indicated us an inverse relationship between the Mediterranean diet and the cognitive deterioration associated with age. From there, establishing relationships between different aspects of these variables can help us better understand the link between Mediterranean diet and healthier aging. Changing ingredients. In its analysis, the team also studied the effects of replacing different sources of fat. Through a substitution modeling, they estimated that replacing five grams of margarine or mayonnaise daily with an equivalent amount of olive oil could be related to a decrease in the risk of mortality associated with the dementia of between 8% and 14%. A similar analysis did not detect similar effects when these fats were replaced by other vegetable oils or butter. 92,383 participants. The study was conducted from the macro -conformation Nurses’ Health Study II and Health Professionals Follow-Upwhich allowed to obtain Information about 92,383 participants. These filled surveys on eating habits every four years over a 28 -year period. The team divided these participants depending on their olive oil consumption: those who never consumed olive oil or did it less than once a month; who consumed up to 1.5 grams per day, who consumed between 4.6 and 7 grams per day; and a group for those who consumed more. The team extended its analysis over 18 years of the study and controlled aspects such as the general quality of the diet or the genetic predisposition to suffer from the disease. The details of the study were published In an article In the magazine Jama Network Open. What is happening? When establishing a causal relationship, it is always convenient to understand what mechanisms are operating behind this relationship between olive oil consumption and death risk associated with dementia. “Olive oil is rich in monounsaturated fats and contains components with antioxidant activity that can play a protective role for the brain,” He explained to the environment UPI Anne-Julie Tessier, co-author of the study.

The relief that Shein has achieved in the United States thanks to the Temporary Tariff reduction Contrast with the new front that opens in Europe. The European Commission and the Cooperation Network for Consumer Protection (CPC), which brings together the national authorities of the Member States, They have notified to the electronic commerce platform that several of its practices vulnea community legislation. Now he has a month to respond and avoid possible coercive measures. According to the official statement of the commissionThe notification is the result of an investigation coordinated by the authorities of Belgium, France, Ireland and the Netherlands. The CPC network It accuses Shein of applying tactics that directly affect consumer rights within the single market. What practices Brussels questions The file open to Shein lists a series of infractions related to the way in which its platform operates and communicates commercial information to consumers: False discounts: Price reductions that are not based on real prices are shown. Pressure tactics to buy: Use of techniques to push the user to finish the purchase. Lack of information or deceptive data: On the legal rights of return and reimbursement, or the way in which they are managed. Deceptive labels: products that appear to have special characteristics when in reality these are minimal legal requirements. Doubtive sustainability promises: Incomplete or false information about the environmental benefits of certain products. Contact difficulties: absence of clear and accessible channels to raise doubts or claims. Brussels is not limited to an informal warning. The notification requires concrete commitments. If in the next 30 days Shein does not respond properly, the national authorities may apply sanctions. Among them, the possibility of imposing fines proportional to its volume of business in each affected country is contemplated. This procedure adds to the ongoing investigation that the Commission itself maintains under the Digital Services Law (DSA). Shein was designated in April 2024 as a “Very large online platform”(Vlop, Vary Large Online Platform), which forces it to meet the strictest requirements in systemic risks, illegal content control and algorithmic transparency. The pressure not only comes from Brussels. Italy’s competence authority has started a procedurealso focused on the company’s commercial practices. In parallel, the Commission has made it clear that these actions do not interfere or limit other possible measures under product safety or data protection. In response to notification, a Shein spokesman declared the Wall Street Journal that The company is actively cooperating with the authorities. “Our priority remains to ensure that European consumers can enjoy an online purchase experience safe, reliable and pleasant”, Said. Shein, as we say, now has 30 days to present his commitments.

Volvo has equipped its electric SUV with a very potent lidar. So much that the risk of frying the camera of your mobile is real

by

Volvo has among its ranks a SUV up to technology, the Ex90. Presented in 2023, it is the electrical alternative to the classic XC90, presuming systems such as the Autonomous Level 3 SAE driving or the equipment of a radar Lidar to detect elements of your environment. What perhaps they had not told you is that, precisely, the lidar sensors of greater capabilities are the archNiene of our usual partner: the smartphone. You can leave you the fried camera. Volvo warns him in his own Support page: Lidar light waves can damage external cameras. The technical explanation is brief, but the message is clear. “Do not point a camera directly when Lidar. Lidar, being a laser -based system, uses infrared light waves that can cause damage to certain camera devices. This can include smartphones or phones equipped with a camera.” Although it sounds like a warning, perhaps something alarming, there are already those who have shown in real time how a lidar can instantly disintegrate the pixels of a mobile sensor. They are not color. They are supposedly fried pixels after burning when aiming at a lidar. The lucky one. In Volvo’s subform in Reddit A video has been viralized in which it can be seen how, when recording the lidar of this electric car, the sensor pixels are gradually burned. Reddit is Reddit and no one can ensure the authenticity of the video, but if we understand the theory behind that a lidar can disintegrate a camera, all the pieces begin to fit perfectly. Your camera sensor. Smartphones use sensors that not only capture visible light (spectrum of 380 to 750 Nm), they are also especially sensitive to near infrared (750 to 1100 nm). In fact, they usually come equipped with an infrared cutting filter in charge of mitigating this light and preventing it from affecting the final result. These filters usually block most infrared light, but they are not perfect. An easy test to do at home is to aim with a TV command to the camera of your mobile. That purple flash that you see is proof that smartphones cameras let infrared light. Destroying pixels. The infrared light emitted by a command has barely power, is emitted in a standard frequency of between 850 and 950 nanometers. What happens to the Lidar del Volvo Ex90? That emits pulsed lasers of 1550 nma wavelength in the middle infrared. This is still invisible to the human eye, but it is a considerable power. If a lidar laser with enough power points directly to a CMOS sensor, it can end up saturating the pixels of it. In other words, it can cause permanent damage and load the pixels that have received their emission of light. A phenomenon studied. Although the Lidar del Volvo Ex90 has put this problem on the table, this is a problem that we have been dragging for more than 20 years. In 2004, studies such as “Lase-Induced Damage Thresholds in Cmos and CCD Sensors ” The destruction of both individual pixels and complete columns after being exposed to compact laser systems was shown. It was highlighted how in wavelengths between 800 and 1,600 Nm (just the latter is the one that caresses Volvo), the damage is irreversible and there is no possible physical defense for infrared protection filters. Lidar in the Volvo Ex90 Volvo is not the only one who warns. Smartphones are not the only devices in using CMOS sensors: the vast majority of consumption miral cameras use this technology. Any manual warnsbefore even starting to explain how the camera works, not directly notice with a laser to the sensor. “When you make Tomas backwards, keep the sun sufficiently far from the viewing angle. Always maintain intense light sources, such as sun, laser or artificial light sources, outside and far from the image area. The concentrated strong light could produce smoke or damage the image sensor or other internal components.” At the moment, Volvo is one of the few companies that, together with Luminar (the company behind its Lidar technology) has detailed the emission of laser pulses in this type of radars. It is expected, however, with the democratization of the Lidar (especially in future cars that will come from China), we have to get used to these power figures.
