China has a nuclear reactor 100 times more efficient than traditional ones. The trick is to shoot atoms with an accelerator

by

China has had one goal in mind for some years: to have a voice in the nuclear race. In the weaponsyes, but also in energy. As Europe argues and the United States attempts to rejuvenate its critical infrastructure to meet AI needs, China has been on the accelerator for months. Recently they have not only approved 10 new reactorsbut they are one step away from turning on a new generation nuclear power plant to provide ‘green’ energy for 1,000 years. This is the CiADS system, or Throttle Actuated System. It is a type of reactor that China has been developing for more than 15 years and that promises to convert waste into energy. Their trick is to convert “garbage” into fuel, and it is a very interesting twist for nuclear energy. And even more so in a China that wants to dominate the atom and renewables as a basis for the development of another of the great ambitions of the country. Artificial intelligence. A twist to nuclear energy In a releasethe Institute of Modern Physics of the Chinese Academy of Sciences gave some details of how this accelerator-driven nuclear reactor works. Uranium is still the fuel, but “reactor driven by an accelerator” is literal. Using a particle accelerator, protons are “shot” at a heavy metal target at a speed of 0.8 times that of light. This generates neutrons that drive a reactor that operates somewhat below the critical threshold to be self-sustaining. The reactor generates energy and this violent reaction causes the long-lived radioactive isotopes that are normally generated in a conventional nuclear power plant to transmute and become materials with a shorter life. As its managers explain in SCMPthe CiADS is a hybrid between a nuclear reactor and a particle accelerator. The main advantage is that greatly reduces the risk of uncontrolled reactionsbut it has another: you can reuse the radioisotopes that normally would be treated as nuclear waste to continue producing energy. Firing beams of protons through these accelerators to bombard the heavy metal makes the uranium-238 give way to a new nuclear fuel: plutonium-239. According to the state media Science and Technology Daily, it is basically turning waste into treasures. According to those responsible, this method is 100 times more efficient than conventional fission and would allow nuclear energy to be converted into “a source of green, safe and stable energy for 1,000 years”, ensuring part of the necessary energy supply for the future. Furthermore, since what would previously be long-lasting waste is reused, the resulting CiADS has a useful life of less than one thousandth compared to conventional waste. The CiADS under construction They are two birds with one stone: China is wildly expanding its nuclear capacity, but it is estimated that it does not have as much uranium of its own and would continue to depend on imports… or to fish it in the sea. With “100 times more efficient” plants, you can get more juice out of what you have. And then there’s the fact that nuclear waste is less dangerous. If everything goes as planned, China will have its first MW-scale CiADS in 2027. It will be then when we check if those theoretical promises achieved by scale prototypes are fulfilled. The CiADS comes at a time when China has emerged as a contradiction in energy matters. They carry years fighting pollution and emissions, but they burn coal. They are a powerhouse in renewables with megastructures and deserts covered by panels. But in the age of AI, it is precisely that coal and gas that is the fuel that allows us to satisfy the demand of data centers at the peak of training. With nuclear weapons, China seeks further reduce your CO2 footprintbut ensuring a future in which it must feed the population, artificial intelligence and a network of technology companies that are doing the most difficult: fighting Western companies without the technological resources of the West. Because right now China doesn’t have the chips or the AI, but yes the energy. And that investment in new generation nuclear plants and, above all, in nuclear fusionrepresents the foundation of what is to come. Everything, that is, if the CiADS works as expected.

A star 1,540 times larger than the Sun is mutating in real time and it is something that baffles astronomers

by

The universe is rarely in a hurry, since stellar processes usually be measured in millions or billions of yearsso witnessing the metamorphosis of a great star in the span of a single human life is practically unheard of. And this is precisely what is happening with WOH G64a true cosmic monster located in the Large Magellanic Cloudabout 163,000 light years from Earth. Big changes. Astronomers have been analyzing this astronomical giant for years, and now the red supergiant is changing radically in front of our telescopes as it heats up rapidly and opens a heated scientific debate. The question that the community is asking itself right now is whether we are facing the transformation towards a very rare yellow hypergiant or if it is simply the fierce interaction of a binary system before collapsing. What we knew. Discovered in the 1970s, WOH G64 has long held the title of one of the largest stars known. The data we know about it is no wonder, since it has a radius 1,540 times greater than that of our Sun, an approximate mass of 28 solar masses and shines 282,000 times brighter than our star. Despite its enormous size, it is an extremely young star, since it is barely 5 million years old. And if we put it into context, in the ruthless world of astrophysics, the largest stars “live fast and die young”, devouring the fuel inside them at great speed. The script twist. Until recently, everything fit the classic profile of an extreme red supergiant, placing its temperature at 3,400 ± 25 degrees Kelvin. But a turning point came in the last decade after the data published in Nature Asia which pointed out that the star suffered a mysterious dimming in 2011, followed by a sudden warming of more than 1,000 ºC and significant chemical alterations in the atmosphere. Now, a new study analyzes the photometry and optical spectroscopy accumulated over more than thirty years of this star. And the conclusion they have reached is that between 2013 and 2014, WOH G64 began to transition from red supergiant to yellow hypergiant. What are they? Yellow hypergiants are an exceptionally rare transition phase of which we barely have data and, above all, it is very ephemeral. In this case, the dramatic thermal evolution could be due to the star having partially ejected its outer envelope or to its stellar companion aggressively stripping away material. The debate is served. As is often the case on the frontier of astrophysics, not everyone agrees that the transition is complete. Rigorous science requires fact-checking constant, and recent research adds nuance to this story. This same year, one study pointed out because the star continues to maintain its classic red supergiant characteristics, questioning whether it has become a rare yellow hypergiant. The most logical explanation they see in this case is that the interaction with its companion star is causing these large temperature changes. This generates a great debate, since it goes completely against the other part of astrophysics that is convinced that we are facing a great twist in the script. A supernova. The big question that everyone is asking is how this titan will end, and some voices suggest that we are seeing the prelude to an imminent supernova. However, in astronomical terms, “imminent” is an elastic concept, since core collapse could occur in a time frame ranging from 100 to a few thousand years. And even if it collapses, even a spectacular explosion is not guaranteed. Although there is also the possibility that it fails in its attempt to explode and, instead, collapses directly in on itself, silently forming a black hole. Likewise, what happens seems to be something that our next generations will see.

If your renovation is a pain, think about the house that cost 120 times more than its original cost: a masterpiece

by

Renovate a house It is usually an exhausting experience: budgets that skyrocket, structural unforeseen events, provisional solutions that end up being permanent. Now imagine that this home is not just any apartment, but one of the great icons of the 20th century, visited by millions of people and examined to the millimeter by historians, engineers and conservators. Then the reform stops being a domestic problem and becomes a continuous battle against time. Thus an icon was born. The assignment that changed a career The year was 1934 when Edgar J. Kaufmann commissioned Frank Lloyd Wright a weekend house next to a waterfall in Bear RunPennsylvania. The architect then took an unprecedented decision: He decided not to look at the water from afar, but to literally build on it. The work, built between 1936 and 1938, almost immediately became in a manifesto of organic architecture: concrete terraces that float over the waterfall, local stone walls that sprout from the rock, spaces that open to the forest as if the house were an extension of the landscape. By January 1938 he already occupied the same cover of time and critics proclaimed it one of the great masterpieces in the history of architecture, one capable of reconcile modernity and nature in an unforgettable image. It happens that there is always a “but” in a work, and one like this was no different. Yes. That perfect image had a disproportionate price from day one. The original cost exceeded the planned budget almost four times and reached approximately $155,000 of the time, a figure equivalent to about 3.3/3.5 million current dollars. Added to this were Wright’s own fees and the expenses derived from a complex execution in a unique but remote environment, so that the project was born already financially stressed. What should be a weekend country house became a total commitment, technical and economic, to materialize a radical vision. And we come to the material that has given the work its name, although it almost took everything away. The gesture that made Fallingwater world famous, its large columnless cantilevers over the waterfall, was also its Achilles heel. During the work, the engineer in charge of concrete warned that only eight reinforcing bars had been placed on a main beam and that, for a span of that length, it should have been duplicated steel. However, Wright rejection the objections, arguing that adding more reinforcement would damage the structure and demanding absolute confidence in their judgment. The contractor, without warning, decided to increase the steel anyway. Even so, when removing the formwork the first cantilever deformed more than four centimeters and was left with a permanent arrow that today translates into a visible slope close to two degrees. And the cracks came before inhabiting it The problems were neither theoretical nor late. Even before the Kaufmann family moved in in 1937, there were already documented leaks and cracks on the concrete parapets. As the decades passed, some balconies began to sink. more than 20 centimeters with respect to its original position, and in the nineties engineers found that the cantilevers they had failed technically and required urgent reinforcements to avoid greater risk. The house that seemed to defy gravity rested on a more fragile balance than the iconic photograph suggested. If the waterfall was the soul of the project, the rain and snow were its nightmare. Flat roofs, terraces that function as roofs for lower rooms and masonry walls holes filled with rubble They made it easier for water to find invisible paths into the interior. So much so that since the 1940s the house was nicknamed with irony by its owners for the number of buckets needed to collect leaks, and almost ninety years later an intervention of 7 million dollars intended to seal covers, inject more than a dozen tons of grout on the walls and improve waterproofing. It didn’t matter the crazy price that had been used previously, many leaks they returned with time. The overhang of the living room seen from the bridge leading to the house At the end of the 20th century and the beginning of the 21st, a structural restoration was undertaken that would be decisive: the beams were drilled and introduced steel cables post-tensioned to “pull” the concrete and recover part of its original position. That operation prevented the sinking will progressbut it did not eliminate the need for ongoing maintenance. To give us an idea, from 1937 to today, the preservation of Fallingwater has already exceeded 19 million dollars, a figure multiplied by about 120 times the initial cost of construction and which illustrates the extent to which keeping the icon standing has been more expensive than its own creation. In 1963 the Kaufmann family donated the house to the Western Pennsylvania Conservancy, which opened it to the public the following year. Since then, more than 6 million of people have visited it, and its status as a National Historical Monument and UNESCO World Heritage Site consolidated his status as one of the masterpieces of the 20th century. Paradoxically, the same audacity that generated the cracks, deformations and leaks is what gave it its symbolic force: Fallingwater, or The Falling House, embodies the rhetoric of the American dream of merging with nature and dominating it at the same time, even when that ambition required paying an enormous structural and economic price. The history of this icon shows that architectural genius is not exempt material risk. Wright’s possibly exaggerated authorship, his conviction towards engineers and contractors, and his willingness to take concrete further of prudent limitsproduced a work that was both sublime and problematic. If you will, it is also an imperfect building that has needed decades of disagreements, revisions and reinforcements to remain standing. And precisely for that reason, more than a frozen postcard over a waterfall, Fallingwater It is proof that great works are born from the tension between vision and reality, and that even masterpieces can always be, literally, at the edge of the … Read more

“The more times you are late for work, the harder it will be for the company to fire you”

by

Arriving late to work every day, leaving before your time or committing various irregularities in your day can cause your company to give you a warning, sanction you or, in the most serious cases, even apply a disciplinary dismissal for breaching the conditions you accepted in your employment contract. However, as labor lawyer Juanma Lorente highlights in one of his recent videosif you do it repetitively and the company does not warn you for it, that violation can become your best ally to protect you from disciplinary dismissal. Being late is bad, but it can protect you. The labor expert explains in his video a legal paradox in which the company’s inaction can turn an infraction into the best defense for a worker against a legal claim for disciplinary dismissal. The lawyer explains the situation with a very simple example: “Imagine that you have been late to work for 2 years. 5, 10 or 15 minutes and the company does not tell you anything. You arrive and sign in with the real time at which you are arriving and the company tolerates it. From one moment to the next, after two years of arriving late, you find a dismissal letter in which they fire you for arriving late.” According to Lorente, this dismissal would be unfair because the company allowed the “habit” of being late for two years, without reacting in all that time. The expert assures that this inaction represents a tacit permissiveness of that conduct, which is why it could not be used as a reason for dismissal before a judge. Silence gives consent. Although it may be incongruous, since the employee’s violation is effectively proven, the repetition of this behavior without a response from the company is known as corporate tolerance. As and how do they count From the Lex-it law firm, this case occurs when a company is aware of the worker’s repeated infraction, such as repeated delays, but does not sanction it for a long time. This means that a subsequent dismissal for the same reason is seen as unfair by the judges, since the company seemed to accept it and “tolerate” the infraction. As the labor lawyer points out, “If he has not previously sanctioned you for the same thing, has allowed it and has tolerated it, he will not be able to use it to fire you.” ​This principle forces companies to follow a scale of sanctions that is applied from the first infraction of employees: from a simple specific warning to suspensions, before reaching disciplinary dismissal. Ignoring this scale of warnings means that the company cannot allege it as a “direct” reason for dismissal because, according to the court, the company tolerated this behavior. The Supreme Court has already applied it. The Supreme Court has confirmed this doctrine in several rulings in which disciplinary dismissals have been rejected because companies have cited infractions as reasons for dismissal that they have tolerated for years without any warning. The result in all cases has been to reject the disciplinary dismissals and declare them unfair dismissals with compensation of 33 days per year worked, despite it being proven that, in fact, the employee had been committing a violation of the conditions for a long time. In one of those sentencesthe Supreme Court states: “Sanctioning with the greatest severity (disciplinary dismissal) conduct that had previously been tolerated, without any prior warning to the employee that such tolerance was going to end, would be contrary to the employer’s good faith.” ​A practical example: he was late 176 times. A very clear example of this legal paradox is found in the case of the employee of an optician in Asturias who arrived late to her job up to 176 times without the company reprimanding her for it. When the company informed him of his disciplinary dismissal, the Superior Court of Justice of Asturias considered it “irrational, disproportionate and incongruous.” The reason was that the company had demonstrated business tolerance by allowing 176 delays without warning or sanctioning the employee, and resorting directly to disciplinary dismissal.

A group of Spanish pilots wait in front of Russia for an alarm that will sound 500 times in 2025. They only have 15 minutes to launch their fighters

by

A few minutes from Russian airspace, a handful of Spanish pilots live in the most tense routine that exists in peacetime: be ready to take off at any moment from an icy base from the Balticone where the sky is watched as if each blip on the radar could be the start of something bigger. Fifteen minutes. At Šiauliai, a Lithuanian air base that functions as first line of surveillance over the Baltic, the routine can be broken at any second with a siren and a countdown. When the alert goes off (in 2025 alone it did so up to 500 times), the Spanish pilots of the 15th Wing They put on their equipment, get into the vans and run towards the hangars with a single objective: to be in the air in less than fifteen minutes. It is a millimetric mechanic, repeated so many times in training that becomes automaticbecause the mission does not wait for anyone and because in that area an unidentified plane, without a transponder or without communication, can be the beginning of a serious incident. The shadow of an enemy. The function of these quick exits, called “scrambles”is to intercept and escort suspicious aircraft until they leave Allied space or their intentions become clear, and in the Baltic they are almost an everyday language. The route is especially sensitive because it connects Russia with the militarized enclave of Kaliningradand there intersect fighters, surveillance planes and traffic that sometimes fly without a flight plan or without the expected signals. The result is constant tension: some days there are several outings and other weeks everything seems calm, but the feeling is always the same, that the next warning can come when you are resting or half asleep. 15th Wing Fighter Mission since 2004. NATO started this baltic air police in 2004 to protect the space of Lithuania, Latvia and Estonia, and since then the countries have taken turns in rotation four months so that the umbrella is permanent. Over time, the deployment was expanded to other bases in the region, first after the first Russian invasion of Ukraine and later with further expansion, because the Eastern Front ceased to be a theoretical concept. In recent months, furthermore, the incursions became more disturbing due to a new detail: not only manned aircraft appeared, but also drones that crossed borders and forced us to react quickly. Spain and the fighters. The Spanish contingent arrived in December with more than 200 troops and eleven EF-18Ma modernized version of the Hornet that Spain operates and maintains ready to fly day or night. The planes are armed with air-to-air missiles and the pilots train with night vision goggles, because surveillance does not stop when the sun goes down. Behind each exit there is a system that monitors the sky relentlessly, control centers that detect traces on the radar and a decision chain that, when activated, turns the entire base into a fast, silent and perfectly rehearsed choreography. Drones change the script. The big twist is that now the problem is not only the classic military plane that approaches without identifying itself, but the emergence of cheap dronesslow, low and erratic, more difficult to classify and more complicated to stop with means designed for another era. It we have counted. In September last year, a wave of Russian drones penetrated Polish airspace during an attack on Ukraine, and then there were similar episodess that forced the activation of fighter jets in countries like Romania. In parallel, small unidentified drones began to be seen near airports, bases and sensitive facilities throughout Europe, fueling the feeling of vulnerability and suspect that someone is measuring response times and blind spots. Crow, the anti-drone. For this reason, in this deployment the 15th Wing arrived with a historical novelty for them: the Indra Crow systeman anti-drone defense that adds a different layer of protection to the base and its surroundings. Crow combines radars, cameras and sensors to detect small aircraft and, once located, attempts to take them down using signal jamming, that is, electronic warfare from fixed or mobile positions. Its range not only protects planes and runways, it also covers the nearby city, because the real goal is to shield critical infrastructure and reduce the risk of a cheap drone causing disproportionate damage. The cost dilemma. Behind this adaptation is a problem that NATO is being forced to solve at full speed: intercepting cheap drones with weapons designed to shoot down fighters is an unsustainable equation. Firing expensive missiles from a fighter jet to take down a small aircraft may work, but it turns every defense in a waste and opens the door to volume saturation. That is why procedures and tactics are being reviewed, looking for cheaper and more specific systems, and assuming that the fighter will no longer always be the best tool to put out the fire. The strategic signal. The arrival of fighters with anti-drone protection It reflects a Europe that begins to fortify the sky as if war were already knocking at the door, although it has not yet fully crossed. In the Baltic, each rotation is a political and military message: there is presence, there is a response and there is an intention to fill gaps that did not exist before. Thus, what was previously an almost routine escort and identification mission is becoming a comprehensive defense exercise against hybrid threatswhere the enemy can be a large plane, a tiny drone or a provocation designed solely to check if, when the alarm sounds, there is really someone capable of taking off in those fifteen minutes.

Producing them emits hundreds of times less than coal and gas

by

All energy sources have their dark side and solar is no exception. Without going any further, we are creating huge mountains of garbage thanks to (or because of) the solar panels cheap. Now, as in any other decision-making, it is time to weigh the pros and cons and compare them with alternatives to have some perspective and here, solar energy does not fare so badly. Damn (blessed) cheap solar panels. The generation of waste from solar panels is a reality that goes hand in hand with the deployment of solar energy. Between 2020 and 2024 the number of solar panels that have gone to waste has multiplied by four according to IRENA reports: from 220,000 to 900,000 tons and be careful because by 2050 have already estimated that the figure will be 250 million tons. The reason? Although their useful life is 25 – 30 years, they are replaced before the end due to incidents such as storm damage or manufacturing defects. In short: replacing is cheaper than repairing. In perspective. But the moment of truth comes from an estimate: the actual waste per megawatt hour of electricity generated. A current standard solar panel weighs about 20 kg and over its 25-year lifespan in moderate sunshine generates about 10 megawatt hours of electricity. The calculation is simple: it is equivalent to 2 kilograms of waste per megawatt hour and is similar to that offered by recent research published in Nature Physicswhich aimed at 1.7 kg/megawatt hour. And now let’s face it against two energy rivals: coal and gas, two fossil fuels that continue to be behind the planet’s electricity generation. coal plants generate between 80 – 100 kg per megawatt hour. And that’s not to mention the 950 kg of carbon dioxide per megawatt hour emitted in combustion. Gas is slightly better: emits 450 kg of CO₂ per megawatt hour generated and no ash generated. But the difference is abysmal compared to the waste from solar panels. In a table on energy generation it is better seen, as this one from Clean Technica: solar panels Coal NATURAL GAS Solid waste (kg/megawatt hour) 2 80 – 100 0 CO₂ emissions (kg/ Megawatt HOUR) 0 950 (per ton) 450 Other emissions No SO₂, NOₓ, particles, mercury… NOx emissions An abysmal difference. That is to say, we are talking about that considering the megawatt hour of electricity generated, a solar panel produces 2 kg of solid waste for about 90 kg of ashes that lead to an emission of 950 kg of CO₂ under the arm for coal and for gas, about 450 kg of CO₂ emitted. Electricity generation plants based on fossil fuels generate continuous and massive atmospheric pollution compared to 0 from solar panels and if we talk about solid waste, coal substantially surpasses it. Not only the quantity, but also the quality. It has already been made clear that the amount of waste is substantially lower, but it is also worth mentioning how harmful this waste is and its consequences. To the remove a solar panel We find a frame made of aluminum, silicon, glass and some plastic, which although technically can be mostly recycled, in practice they are not recycled circularly. It is true that there are panels with traces of heavy metals such as lead (solders) or cadmium in thin film panels, but also that the EU counts with management programs for this waste. And the solar panels do not emit pollutants while they are operational. Coal ashes have a list of traces fearsome: in addition to lead and cadmium there is arsenic, mercury, selenium, uranium or thorium. This cocktail is a risk to health and the environment due to inadequate management or spills. There is no need to talk too much about carbon dioxide emissions: they are behind the global warming. Coal combustion alone generated 15 gigatonnes of CO₂ between 2020 and 2024, according to analysis by the Global Carbon Project. This another study from the British Medical Journal relates air pollution from fossil fuels to some five million premature deaths last year, mainly respiratory diseases, cardiovascular diseases, and strokes. Solar energy waste is not the problem. Clean energies are not perfect and their operation involves a series of challenges. As we have seen, in the EU in fact recycling infrastructure already exists which currently manages to recover up to 95% of these (the WEEE directive establishes a minimum recycling of 85% of the modules) in consolidated, scalable processes and result in small, manageable and moderately harmless final waste. With the data in hand, it is substantially clear that yes, waste from solar energy exists, but viewed from the perspective of current energy needs and the sources that provide it, they are not the problem at all.

The US offered NVIDIA chips to China. China has responded with a “no, thank you”, according to the Financial Times

by

China has turned the technological development in state policy. The country is shaking up its economy through robot development (some already working in stores or in disasters), artificial intelligence and, above all, chips. Giants like Huawei and companies like SMIC are developing chips with one goal in mind: eliminate dependence on the United States. However, some of these companies need to access powerful and reliable chips immediately, and NVIDIA had presented itself as the best option. It seems that everything has been a mirage. Full speed ahead. The current technology war between the United States and China means that Western companies cannot do deals with Chinese ones. This includes the sale of advanced chip making machinesbut also that NVIDIA, for example, can’t even sell its advanced chips like the previous generation. A few weeks ago, however, the United States relaxed its policies, which opened the door so that NVIDIA could sell the famous ones again H200 to certain Chinese customers. The US was going to take a 25% tax on each sale and it was a win-win: Chinese customers had access to renowned chips and NVIDIA managed to take part of the Chinese pie (a pie of 50,000 million dollars). At least until local companies develop their alternatives. Last week we already said that NVIDIA had increased production waiting for two million orders. But there is a problem: a sudden stop. With Customs we have encountered. At that time, China had not commented and the person most interested in the operation, Jensen Huang, CEO of NVIDIA, commented that if the orders were arriving it is because someone had authorized them. That was taken as a silent confirmation from China, but now there is news. Although the country still has not made an official statement, since Financial Times They point out that NVIDIA was surprised to find that customs had stopped the orders. According to sources consulted by the media, customs officials in China recently summoned logistics companies from Shenzhenone of the neural points of technological innovation of the country, to warn of something: they could not submit shipping requests for the H200 chips. National chips please. That pressure has led the company to pause production. All there is is uncertainty right now due to a chain of events that show that NVIDIA was crazy about selling. After putting pressure on both governments, Huang managed to get the US to give approval for the sale in China, but China did not comment, something that the US company took as an approval. Chinese policy for a few months has been very clear: favor and promote local industry with one goal: ‘Delete America’. China seeks technological sovereignty through giants like the aforementioned Nvidia, but also with others like Moore ThreadsBiren, MetaX or Enflame. black market. However, the fact that orders cannot be placed to buy NVIDIA chips does not mean that NVIDIA chips are being stopped: As already pointed out Reuters a few months ago, that ban and the veto on the sale of sophisticated chips has promoted a black market of American chips, especially the B200 and B300 from NVIDIA, more powerful than the H200 that the US Administration authorized. There is talk of a market of more than 1,000 million dollars, and although NVIDIA had hopes of re-entering the country through official channels, it seems that the Government is going to continue encouraging its technology companies to bet on ‘Made in China’ solutions.

The Spanish business that Vodafone sold as ballast is now worth three times as much. Zegona has shown that the problem was the owner

by

according to further Populi Voicea medium with a good track record in telecom exclusives, Telefónica has started talks with Zegona to acquire Vodafone Spain. The negotiations are recent (just a few weeks) and it was Movistar who picked up the phone first. Telefónica wants to close the operation in the first half of 2026. The rumors come from months ago. The problem is that arrive late, and that has a price. A little more than two years ago, Zegona bought Vodafone Spain for about 5,000 million euros. Vodafone (the British parent) was selling a problematic asset: It was the third operator in a market of four. He was caught between the scale of Telefónica and the agility of the low-cost He inherited a network that required constant investment. And he also inherited a tarnished reputation after years of complaints. For the British group, Spain was a drain of money and effort. For Zegona, a poorly managed gold mine. And in just two years, the fund has proven that he was right: Has returned to its shareholders 1.4 billion euros in dividends (28% of what was paid by Vodafone Spain). Has reduced the number of shares in circulation by 69%. And yet its current capitalization is around 3.6 billion. For fund shareholders, the return has been spectacular: The stock went from 345p when they bought Vodafone (less than 100 when they announced their intentions) to over 1,565p now. It has multiplied by 4.5 in two years. Vodafone Spain generates around 4.5 billion annual revenues and, with more focused management than before and without the bureaucracy of a global giant, it has become a profitable operation that Zegona can continue to exploit… or sell to the highest bidder. Telefónica is now negotiating from a weak position. It needs the operation (Marc Murtra has repeated that Movistar must lead the consolidation of the Spanish market) and the market knows it. An ERE of 4,500 people has just closed. And while Telefónica prepared the house to add more furniture, its price has fallen 27% since the end of October. Zegona, however, its value has skyrocketed. The price of this indecision is between 2,000 and 7,000 million extra euros. regarding what the purchase of Vodafone Spain would have cost in 2023. Zegona is in no hurry. It can wait, it can squeeze, it can even stay as it is. Telefónica now cannot afford that luxury because buying Vodafone Spain is not an expansionist move, it is an almost defensive necessity: needs critical mass before Europe forces further consolidation where Movistar is the main course, not the diner. But when negotiating is a necessity and the other side knows it, the price stops being a variable and becomes a toll. If the operation crystallizes, it will create a giant with more than 45% of the Spanish market, great cost savings by eliminating duplications (headquarters, networks, contracts…) and intense regulatory scrutiny from Brussels. Although not as brutal as it would have been with Vestager because Ribera has another look. Telefónica knows it and so does Zegona. The difference is that one is late and the other can afford to wait. That changes everything in a negotiation.

Science reveals that the weight returns four times faster than with a diet

by

The era of “miracle” drugs to treat obesity is entering a phase of crude scientific maturity, thanks to the time that has passed since its launch on the market. In this way, despite the years with big headlines pointing to great weight losses with Ozempic, science is now able to provide more answers to the key question What we should ask ourselves: what happens when we stop pricking ourselves? The problem. When a drug is newly released to the market, long term effects It is something that is not known exactly, since patients need to be taking them long enough to see the effects they cause. And above all the effect that exists when the drug is removed from the body. To answer this with Ozempic we have a study led by the University of Oxford which is not minor at all, since it has analyzed more than 9,300 adults in 37 different clinical trials. And the conclusion they have been able to draw is quite clear: patients regain weight when they stop treatment at a rate of 0.4 kg per month. The comparison. At first glance, this figure seems really low, but if we compare it with other methods to lose weight, we see that the magnitude of the problem is not minuscule. The study itself indicates that in behavioral programs, such as a diet and an increase in physical activity, the effect after its withdrawal is an increase of 0.1 kg per month. This way, the rebound effect of slimming drugs It causes you to return to your initial weight in approximately a year and a half, while a change in eating and sports behavior takes around four years. New generation drugs. But this is a simple average between the different medications on the market. This implies that within GLP-1 agonists we can see that the most powerful drugs also have a much greater rebound effect. For example, in the case of Wegovy or Mounjaro, where the initial loss was 14.7kg, the rebound was seen to shoot up to 0.8kg per month. An effect that tells us that the body tries to recover lost ground at twice the speed of previous generation drugs. Cardiovascular health. Beyond the aesthetic, science pointed out that these drugs had the ability to reduce the risk of heart attacks and improve the metabolic health. But it seems these effects are completely temporary. Specifically, the study has seen that approximately a year and a half after stopping the medication, the majority of cardiometabolic markers return to their levels before starting treatment. For example, blood pressure increases, diabetes markers reverse their improvement, and total cholesterol also returns to its risk levels. Why the rebound is so fast. The answer to this could lie in our own biology. Science believes that this effect is due to the fact that by injecting massive doses of GLP-1 agonists (a hormone that is produced in small quantities when we eat) we could be destabilizing our own cell receptors. Or we would even be blocking our body’s natural production of this hormone that gives us satiety. That is why when withdrawing the drugthe system does not have the ability to produce this hormone again in the same way as before (as if it had to turn the system back on) and that is why the body’s satiety system goes deaf. The result? Well, logically, the appetite returns with great intensity, causing the patient to eat much more food, since they are not satiated and in this way the weight increases again. The myth of the magic bullet. There are hardly any miracles in medicine, even though we say that these drugs are. And the reality is that these drugs are not the definitive solution for obesity, since real data indicates that the majority of patients stop treatment after 12 months due to its high cost, the fatigue of injecting or side effects. But in addition, there is no awareness that this treatment is a simple aid to self-regulation, but that logically it must be accompanied by a dietary change and physical activity that must be continued once the treatment is finished. If not, we can be sure that the injections will be of absolutely no use. A paradigm shift. This meta-analysis marks a turning point. Science tells us that GLP-1 is extraordinarily effective, but it is not a cure. If we treat them as a six-month “crash plan”, we are condemning the patient to a more aggressive yo-yo effect than any miracle diet of the past. The solution, according to Qi Sun and the Oxford researchers, is not only in the syringe, but in public policy: taxes on ultra-processed foods, aid in the purchase of fruits and vegetables, and urban planning that encourages exercise. Without a change in environment, the drug is just a temporary truce in a war the body is programmed to win.

The owner of an Audi A3 was fined three times for driving without a license. On the fourth, the court took away the car

by

What prevents a driver from driving without a license? Obviously, the law. But going down to a purely practical field, what prevents a driver without a driving license from going to the garage at home, taking his car, turning the key and putting it in first gear to take the car to work, take a walk or go out? That’s what has happened in Vigo where Justice has only found the way out for one woman: to take away her Audi. The Provincial Court, tired of imposing sanctions on him that emphasized that he was prohibited from driving, has decided to confiscate his Audi to avoid greater harm. By then the sentences had had “no deterrent effect,” in the words of the ruling. Either you give it to me or I’ll take it from you There are not many violations for which they can keep our car. There are not many reasons why they can revoke our driving license. Surely you have already found one of them. Bingo. A positive for alcohol or drugs leaves, for the moment, the car immobilized and depending on the severity of the positive, it can leave us without a driving license. In cases that the car is immobilizeda passenger who does not test positive may well take charge. alcohol control Or a family member or friend can come pick it up, as long as the immobilized car is not hindering driving. If neither of these two cases occur, the tow truck comes and takes it to the municipal warehouse. The next day, the car can be removed. By a person who has a driver’s license, of course. But, as we said, what really prevents a person from taking their car again when they arrive at the garage at home? The limits have been found by the resident of Vigo who stars in a story collected by The Voice of Galicia. The Provincial Court has ended up confiscating his Audi to prevent him from driving again without a license and in the process has answered the question of how many times is too many times. They explain in the Galician media that on March 15, 2025, she was caught driving without a valid driving license because all her points had previously been removed. Taking charge of the case, the Criminal Court sentenced him to six months and one day in prison for a crime against traffic safety. But he applied a less common decision: seized his Audi A3. The reason is that the convicted woman was the fourth time she had faced justice for similar events. To the point that the judge in charge pointed out that his record includes three other similar convictions in just 11 months. On those three previous occasions, the driver was fined for driving without a driving license. In the third, in addition to the financial penalty, he was imposed 60 days of work for the benefit of the community. On the fourth occasion lost the Audi A3 with whom he was driving. Upon hearing the verdict, the accused appealed to the Pontevedra Court, alleging that the three previous convictions for the same reason (driving without a license) are not enough to apply the aggravating circumstance of multiple recidivism. In addition, he requested that a mitigating circumstance be applied for drug addiction and asked that the car be returned because he considered that the measure was disproportionate and unjustified. For its part, the Pontevedra Court has confirmed that the seizure of the vehicle was a correct measure because the three previous convictions had had “no deterrent effect.” In addition, he emphasizes that the car itself was a “potentially dangerous instrument” since the driver had been detected driving without lights at night or under the influence of drugs.
