Working in a nuclear power plant is not the best way to avoid cancer. Now it turns out that its waste also serves to cure it

by

If there is a terrifying and mainstream disease, it is cancer: after all, according to the WHOone in five people will develop it at some point in their life. Although in some cases the risk factors vary depending on the type of cancer, working in a nuclear power plant poses some riskas long as there is greater exposure to ionizing radiation, even if there are no accidents or more intense exposure through maintenance work. Paradoxically, the activity of nuclear power plants, which can cause cancer, also serves to generate the basis of the medicine to cure it. And we are not talking about a potentially distant study, but rather something that can already be materialized. In fact, the United Kingdom has already taken a step forward to transform some of its radioactive waste into anti-cancer medication. The world’s first lead-212 radiopharmaceutical ecosystem. Because in the UK they have closed an agreement between the public body Nuclear Decommissioning Authority and the biotechnology company Bicycle Therapeutics for which the latter will have 400 tons of reprocessed uranium to extract the valuable (for the medical industry) lead – 212 for 15 years. Behind Bicycle is Sir Greg Winter, co-founder of the company and winner of the Nobel Prize in Chemistry in 2018. This will provide them with the infrastructure to create the world’s first end-to-end lead-212 radiopharmaceutical ecosystem, from discovery to commercial supply. So explains it Mike Hannay, Chief Product and Supply Chain Officer at Bicycle Therapeutics. The benefits of lead – 212. Lead – 212 is an isotope used in therapeutic contexts thanks to its particular decay properties, so that it emits both alpha and beta particles. While the former provide high-energy, short-range cytotoxicity, the latter have a more extended range, targeting micro-metastasis. In a simplified way, this medically applicable isotope is essential for precision treatments against tumors resistant to other therapies. Thus, it carries radiation and acts directly on cancer cells to destroy tumors, minimizing the damage to the surrounding healthy tissue. This type of technique offers promising results in prostate cancers and neuroendocrine tumors of organs such as the intestine or pancreas. Extracting lead-212 is an arduous task. Converting the waste from nuclear power plants into cancer treatments seems like a fantastic idea for two reasons: because of the cure for cancer itself and the problem of dealing with radioactive waste, one of the great challenges faced by these energy industries, which have also explored other avenues such as take advantage of the remaining energy. But getting here has not been easy: the extraction process of this isotope has been carried out by the United Kingdom National Nuclear Laboratory (UKNNL) with a complex chemical process that requires the isolation of scandalously small quantities of the precursor material from the used nuclear fuel. Thus, first the Thorium-228 is extracted from the reprocessed uranium to later process it into Radium-224. It is then loaded into a lead-212 generator that has been custom-made for Bicycle Therapeutics’ needs by US company SpectronRx. This is a continuous regeneration, producing enough lead-212 to deliver tens of thousands of doses of precision therapy per year. The laboratory explains that the critical part is in the beginning: “The initial precursor material extracted is comparable to finding a single drop of water in an Olympic swimming pool.” From that minute amount, an even smaller fraction of lead-212 is separated. First discover the universe, then cure cancer. In addition to this unexpected use of nuclear power plant waste, in recent weeks a group of researchers from the University of York have evidenced in a study that the intense radiation captured in the beam absorbers of particle accelerators could be reused to produce materials used in cancer therapies. Those particle accelerators They are used, among other things, in experiments to discover the matter of which the universe is composed. In Xataka | The rarest element on Earth aims to cure cancer.

Something is going wrong with AI. The US is turning to energy solutions that it thought were buried to power data centers

by

The race to develop and operate increasingly powerful artificial intelligence models comes at a cost that is rarely at the center of the technological narrative. It is not in the chips or the software, but in the huge amount of electricity needed to keep active data centers running around the clock. In the United States, this pressure is already being translated into concrete decisions: polluting power plants that were in retirement are being restarted to cover increasing peaks and tensions on the grid. The paradox is evident, the most ambitious advance in the technology sector depends, for the moment, on energy solutions from another era. The problem is not so much an absolute shortage of electricity as a time lag. The demand for data centers linked to AI it’s growing much faster than the ability to launch new electrical generation, especially renewable, in short terms. Building large energy infrastructures takes years, while these complexes can advance in much shorter time frames. Faced with this temporary shock, network operators and electricity companies are turning to what already exists and can be activated immediately, even if it is more polluting. PJM in context. The clash between electricity demand and supply is perceived with special clarity in the PJM region, the largest electricity market in the United States, which covers 13 states and concentrates a very significant part of the country’s data centers. We can understand it as a large regional electricity exchange that coordinates generation, prices and network stability in real time. There, the growth of data centers linked to AI is putting to the test a system designed for a very different consumption pattern, making PJM the first thermometer of a problem that is beginning to appear in other areas. What is a central peaker. The calls central peakeror peak, are facilities designed to come online only during short periods of peak demand, such as heat waves or winter peaks, when the system needs immediate reinforcement. They are not designed to operate continuously, but to react quickly. According to a report According to the US Government Accountability Office, these facilities generate just 3% of the country’s electricity, but they account for nearly 19% of the installed capacity, a reserve that is now being used much more frequently than expected. South view of the Fisk plant in Chicago The case of the Fisk plant, in the working-class neighborhood of Pilsen, in Chicago, illustrates well how this shift translates on the ground. It is an oil-fueled facility, built decades ago and scheduled to be retired next year, that had been relegated to an almost testimonial role. The arrival of new electrical demands associated with data centers changed that equation. Matt Pistner, senior vice president of generation at NRG Energy, explained to Reuters that the company saw an economic argument to maintain the units and that is why it withdrew the closure notice, a decision that returns activity to a location that many residents believed was in permanent withdrawal. When the price rules. The change is not explained only by technical needs, but also by very clear market signals. In PJM, the prices paid to generators to guarantee supply at times of maximum demand skyrocketed this summer, more than 800% compared to the previous year. An analysis by the aforementioned agency shows that about 60% of oil, gas and coal plants scheduled for retirement in the region postponed or canceled those plans this year, and most of them were units peakerjust the ones that best fit in this new scenario of relative scarcity. The bill for this energy shift is paid above all at a local level. The power plants peaker They tend to be older facilities, with lower chimneys and fewer pollution filters than other plants, which increases the impact on their immediate surroundings when they operate more frequently. Coal is also postponed. The phenomenon is not limited to power plants peaker fueled by oil or gas. On a national scale, several utilities have begun to delay the closure of coal plants that were part of their climate commitments. A DeSmog analysis identified at least 15 retirements postponed from January 2025 alone, facilities that together represent about 1.5% of US energy emissions. Dominion Energy offers a clear example: In 2020 he promised to generate all its electricity with renewables by 2045, but after the company projected that data center demand in Virginia will quadruple by 2038, it is now taking a step back.

The European Bizum wants to be working next Christmas, but first a problem must be resolved. One of power sharing

by

“Wow, but if it gives me the option to pay with Bizum, how cool.” That was my expression a few months ago when in an online purchase the online store offered me to pay directly like this. No debit or credit card, no Google Pay. With a Bizum. The instant payment system that is triumphing in Spain is so good that What we want is for it to work further. And that is precisely what the banking entities of the European Union want, who saw a “European Bizum” as a great idea. There’s just one problem. Who will control it. The European Bizum is approaching The European Central Bank he has been fighting for five years for that application that does the same as Bizum but throughout Europe. There was a major power struggle here with two large factions. On the one hand, the consortium Spain-Italy-Portugal. On the other, that of France-Germany-Belgium-Holland, who wanted to impose its own Bizum, called Wero. Fortunately, in recent months we have seen how the positions of both consortiums have become closer and the unification now seems almost definitive. This is what they indicate in five dayswhere they quote “market sources” who talk about the agreement being signed in early 2026. The European Bizum should start operating at the end of next year if everything goes as expected. This system may not be a new application, as requested by the French and German entities, but rather a system that interconnects existing ones. It is a somewhat more confusing solution but also more practical, because users will not have to change apps. For example, a Spanish user will be able to send a Bizum to a German at no cost, and the German will receive that money in his Wero app in a way that is transparent to him. The European banks participating in the negotiations have reached an agreement to establish a new company that will be the owner of this interconnection technology. There was talk of applying certain commissions, “but it was finally rejected in favor of a multilateral network.” Power distribution And there is the new challenge: Who is in charge in this new society? The distribution of power is now the great unknown, and there are several options. On the one hand, each national platform receives practically the same participation. On the other hand, the distribution should be made based on the volume of each country and then corrected. The Bizum model seems like it can also be applied to that pan-European solution. It is interesting to realize that as explained in the economic newspaper, the owners of Bizum are 22 Spanish banks, among which the participation varies: Caixabank: 25% Santander: 21% BBVA: 18% Sabadell: 12% Other minority banks such as Unicaja, Bankinter or Cajamar have lower participations, but Bizum’s statutes establish that no bank can have more than 25% participation. Do we need a digital euro? Europe has been looking for a solution for some time that would allow it to mitigate its dependence on the two great giants of electronic payments: Visa and Mastercard. The European Payments Initiativecreated in 2020 by 16 banking entities, had precisely the objective of creating a European interbank network that competed with these platforms and with others such as PayPal. And little by little it has been proven that Bizum was precisely a great candidate to achieve this. The application, with more than 30 million users in Spain, has not stopped growing in benefits and alliances like the one a year ago they signed with Revolut. There are still other obstacles in the creation of this European Bizum. For example, building a common deposit guarantee fund to deal with large US entities. It does not seem that this is going to be a major impediment to the implementation of the pan-European alternative, and that makes us wonder what happens now with the digital euro. The European Central Bank (ECB) has been designing the design of this digital asset for years. There have also been important movements in that sense, and if the European regulations are approved in 2026, there will be a pilot starting in 2027. The EU seems to want to be ready for a possible first broadcast in 2029. However, that European Bizum will theoretically solve part of what the digital euro wants to achieve, so does it make sense? It is very likelyespecially since the digital euro is a legal tender issued by the ECB. It is not just a way to transfer money, but a digital form of official money itself. Both alternatives can coexist, and this European Bizum may be the best way to promote the use of the digital euro.

We have a problem with cardboard recycling. In the United Kingdom they believe that the solution is to use it in a power plant

by

Every day, millions of cardboard boxes leave our homes heading to the blue container. They are the last link in an accelerated consumption cycle in online commerce. However, this material, so everyday that we don’t even look at it twice, could be on the verge of an unexpected second life: becoming fuel to generate electricity on a large scale. A residue that enters the energy map. A team of engineers from Nottingham University has shown for the first time that used cardboard can be used as an effective source of biomass in power plants. The investigation, published in the journal Biomass and Bioenergycompares cardboard with a common reference for industrial biomass: eucalyptus. The engineers didn’t just watch the cardboard burn. They crushed it, studied its shape, broke down its chemistry and analyzed how it reacted to heat and what type of carbon it left behind. They even developed their own method—based on thermogravimetric analysis—to measure exactly how much calcium carbonate each sample contains. This component, common in printed cardboard, gives rigidity to the material but also conditions its behavior when burning. Thanks to this procedure, they can predict which type of cardboard will work well in an industrial boiler and which could cause problems. The science behind cardboard that burns “better.” The study did not stop at theories. He tested the combustion of cardboard in two types of systems equivalent to those used in power plants: Drop Tube Furnace: Simulates the rapid combustion of pulverized biomass.Here, the researchers observed that cardboard particles develop chars (the carbonaceous remains that remain after the first combustion phase) highly reactive, with a predominance of fine and porous structures that favor a burnout accelerated. Muffle Furnace: Simulates fluidized bed or grate systems. Even with longer residence times, the paperboard maintained its excellent combustion profile. In addition, the size and shape of the particles were characterized through an analysis with more than one million particles per sample; The tendency of cardboard to form “spongy aggregates” during grinding was observed—a challenge for its industrial handling—and characteristics such as sphericity and aspect ratio were correlated, something that could improve future combustion models. As the academic study explains, this detailed analysis allows predicting combustion efficiency and designing industrial strategies to integrate cardboard into the fuel flow. The result was very favorable. Thanks to this experiment, the engineers managed to demonstrate that cardboard has less carbon (38%) than eucalyptus (46.7%) and its calorific value is also lower (15.9–16.5 MJ/kg versus 21 MJ/kg). However, its chars are finer, porous and reactive, which accelerates combustion; In addition, it contains much more ash (8.9–10.6%, compared to 0.6% for eucalyptus), a critical aspect for boilers. What remains to be resolved? Although the technical potential is evident, the study makes it clear that cardboard is not ready to enter the boilers of a power plant tomorrow. There are three fundamental challenges that must be addressed: Management and processing problems. When ground, cardboard does not behave like wood: it forms spongy lumps of very low density that make internal transport difficult, complicate the continuous feeding of boilers and can increase the risk of blockages and accumulations. The study warns that it will be essential to adapt the grinding and feeding systems to guarantee a stable and safe flow. The behavior of calcium. Cardboard contains very high levels of CaCO₃, especially when printed. This calcium can behave in different ways depending on the temperature and type of boiler. In certain cases it raises the fusion temperature of the ashes – which is positive -; In others it can favor the formation of slag or alter the quality of the fuel. The study recommends analyzing the behavior of cardboard according to the type of plant, because not all technologies tolerate these variations in the same way. Large-scale industrial validation. Laboratory tests are promising, but the decisive step is missing: testing the cardboard in real operating conditions. According to the researchers, the industry will have to carry out tests on different technologies in boilers, evaluate emissions, study the accumulation and composition of ash and check their compatibility with existing biomass mixtures. Only then can it be determined whether the cardboard can be safely and stably integrated into the mix of biomass. An everyday material with an unexpected future. Cardboard protects pizzas, televisions, books and appliances. We recycle it without thinking too much about it. But this research from Nottingham suggests that this everyday waste could become another piece of the energy transition, helping to diversify fuels and take advantage of an abundant and local resource. Today we see it as garbage. Tomorrow it could help produce electricity. The spark has already been lit: now we need to know if the industry wants – and can – convert it into real energy.

In 2011 Japan closed the largest nuclear power plant on the planet. Now he has decided to reopen it in the midst of the energy debate

by

The nuclear debate, which Japan thought closed, returns to the scene. The authorization of the governor of Niigata to reactivate Kashiwazaki-Kariwa, the largest atomic plant in the world, has set off alarms: citizen distrust, the shadow of Fukushima and doubts about whether TEPCO is the right company to lead the country’s new energy stage are emerging. A new nuclear revival? The Kashiwazaki-Kariwa plant, managed by Tokyo Electric Power Company (TEPCO), has not produced a single kilowatt since 2012. The closure was a direct consequence of the 2011 tsunami and the three meltdowns from Fukushima Daiichia blow that left reactors with similar designs under suspicion. That technical coincidence was enough to keep its seven reactors on hold for more than ten years, despite the fact that the plant was essential for the electricity supply of northeastern Japan. According to Japan TimesHideyo Hanazumi has authorized a step-by-step reactivation that will start with reactor 6—one of the most recent and powerful—and that, later, will also include reactor 7. Altogether, the complex exceeds 8,000 MW of capacity, a figure that not only imposes: it maintains it as the largest nuclear facility on the planet. A significant change for the Japanese country. Kashiwazaki-Kariwa has gone from a technical project to a strategic move. As reported by the Financial TimesTokyo trusts that its reactivation will contribute to lowering the electricity bill and ensuring energy sources with fewer emissions, at a time complicated by the Russian invasion of Ukraine and the fall of the yen, which makes fossil fuel imports more expensive. Japan, which before Fukushima generated almost 30% of its electricity with atomic plants, fell to practically zero after the disaster. Since then 14 reactors have reopened and others await local or regulatory approvals. The government aims for nuclear energy to once again represent 20% of the mix in 2040. In addition, TEPCO would improve its annual accounts by around 100 billion yen thanks to the restart, according to Japan Forwardat a time when it continues to face enormous costs for the dismantling of Fukushima Daiichi. The reactivation process. The restart will begin with unit 6, which already has fuel loaded and will begin commercial operations before March of next year. To move forward, TEPCO must respond to the Government’s demands, which include updating all security systems and improving emergency evacuation plans. The process has not been easy. As detailed by Japan Timesthe plant passed safety reviews in 2017, but then suffered a veto from the Nuclear Regulatory Authority due to deficiencies in anti-terrorist measures, lifted in 2023. In addition, TEPCO had to incorporate biometric controls and correct security flaws after new internal incidents. Is there controversy? Yes, and a lot. According to a survey cited by the BBC50% of Niigata residents support the revival, while 47% oppose it. However, almost 70% express their concern because the person operating the plant is the same company that caused the accident. From Japan Times He adds that the rejection intensifies in some of the towns located within 30 kilometers of the plant, where the majority fear a new disaster or distrust the company. Another source of discomfort, also pointed out by this medium, is that the electricity generated is not used in Niigata, but in the Tokyo region. The political dimension is equally tense. Hanazumi, aware of the sensitivity of her decision, has announced that he will submit his continuity as governor to the vote of the prefectural assembly, the only body that can remove him. But there is something else at play. The reopening of Kashiwazaki-Kariwa is seen as a pillar to ensure the country’s energy security and avoid possible power outages in Tokyo. It would also allow reducing electricity rates that have increased notably since 2011. At the same time, Japan is not only restarting reactors: it is also is planning the construction of new plants with fourth generation reactors, which would mark a new chapter in the country’s energy policy. More than a return to the atom. The country that one day vowed not to depend on atomic energy again has ended up returning to it, driven by necessity, geopolitics and the urgency to decarbonize. It remains to be seen if this decision will also ignite the confidence of a citizenry that still carries the memory of Fukushima or if, on the contrary, the return to the atom will deepen a division that has been open for more than a decade. Although the governor’s approval is the decisive step, there are still procedures: the prefectural assembly must debate and vote on the decision in December, and the Japanese nuclear regulator must complete the formal procedures for reactivation.

Reopening nuclear power plants sounds very spectacular, but Google has a plan B in case it’s not enough: solar energy

by

Data centers for are insatiable monsters those who are responsible for them must feed. OpenAI, Meta, Microsoft, xAI, Anthropic and Google are burning money riding colossal data centers for training and management of artificial intelligence. But these installations are not expensive to set up: they are also expensive to maintain. They require a considerable amount of energy to functionand Google has just received a ‘shot’ of renewables. All thanks to a direct connection to the largest system in the United States. Renewables to power AI. Google and TotalEnergies have just signed a agreement of energy purchases for 15 years. The contract stipulates that the energy company will deliver 1.5 TWh of electricity from its Montpelier solar plant, in Ohio, to Google. The plant is still under construction and they estimate that it will have a capacity of 49 MW, but the most important thing is that it will be connected directly to the electricity system. PJM. It is the largest network operator in the United States. It covers 13 states and data centers are representing a relevant portion of the operator’s pie: in its last annual auction, the load of these facilities PJM capacity sale triggered at 7.3 billion dollars, 82% more. Astronomical needs. In the statement from TotalEnergies, the company that this agreement illustrates its ability to meet the growing energy demands of the major technology companies. The problem is that it is not enough. If we focus on Google, the consumption of its data centers was 30.8 million megawatt hours of electricity. The company has been focused on AI for years, but the recent ‘boom’ has made it double what its centers consumed in 2020 (14.4 million MWh). Currently, data centers are estimated to account for 95.8% of Google’s total electricity budget. But it’s not just Google: the International Energy Agency esteem that global data centers consumed 415 TWh last year, representing approximately 1.5% of global electricity consumption. It seems little put in percentage, but Spain consumed in 2024 231,808 GWh, or 231 TWh, in 2024. The data centers of a handful of companies alone consumed twice as much as an entire country. And the estimate is that this data center consumption will double by 2030, reaching 945 TWh. Renewables are not enough. Now, although renewables are a support for the total energy required by data centerssolar and wind power have two limitations: intermittency and variability. Generation depends on weather conditions and time of day, meaning it fluctuates dramatically even throughout the same day. This instability clashes head-on with the high reliability and availability requirements of data centers. These are installations that must operate continuously and cannot assume cuts or Unforeseeable drops in supplysince AI or cloud storage would suffer the consequences. These renewables require backup batteries, but it is complicated and expensive to have such a large number of batteries just to power data centers. Pulling the gas and looking at the nuclear. That’s where other sources come into play. On the one hand, nuclear. In October 2024, Google signed the world’s first corporate agreement to acquire nuclear energy from SMR reactors. The first will come into operation in 230 and it is expected that, together, they will be able to satisfy the technology company with 500 MW of capacity by 2035. On the other hand, natural gas. In October of this year, the Broadwing Energy Center project began, a new natural gas power plant that will have a capacity of 400 MW and is scheduled to come into play at the end of 2029. Decarbonization and pressure. And the big question is… doesn’t the use of gas for AI clash with the technology companies’ objectives of achieving decarbonization percentages for both 2030 and 2050? We have already seen that oil companies have been getting off the renewables bandwagon because they have seen that fossil fuels are still relevant in the technology industry, but in the case of Google, they rely on the fact that projects like the Broadwing Energy Center They will have CCS systems. This means that it will have carbon capture system that will be able to permanently “sequester” 90% of the emissions. It means burying the problem, literally, since the CO₂ will be stored a mile underground. In 2020, before the AI ​​boom, the company established the goal of operating with carbon-free energy 24 hours a day, seven days a week by 2030. It will be interesting to see how they plan to offset these emissions thanks to renewables, but the IAE estimates that the demand for data centers will not stop growing in the short term and that adds another problem: a increased pressure on the electrical grid which is added as another element to manage. Because the big underlying problem is that the demand for energy is growing at a faster rate than the capacity to generate new electricity, and it is something that has an impact on companies’ bills, but also in homes.

The largest nuclear power plant in Europe has been connected to diesel generators for a month. It’s as encouraging as it sounds.

by

Europe is once again walking a nuclear tightrope. After more than three years of war, the largest atomic plant on the continent —the Ukrainian Zaporizhia plant— has gone from being an industrial symbol to becoming at a point of friction capable of triggering an emergency of continental reach. In parallel, other plants in the country operate at reduced power after attacks on the electrical grid. The situation is so unstable that the director of the International Atomic Energy Agency (IAEA), Rafael Grossi, recently traveled to Kaliningrad, Russia, for emergency talks with the head of Rosatom, Alexey Likhachev, according to the Anadolu agency. It is a gesture that reflects the extent to which the risk is real. An attack that left two centers at minimum. According to a statement from the IAEAa military attack during the night of November 7 damaged an electrical substation critical to nuclear security. This incident left the Khmelnitsky and Rivne plants disconnected from one of their two 750 kilovolt lines and forced the electricity operator to order a power reduction in several of its reactors. Ten days later, one of the lines was still out of service and three reactors continued to operate at limited power. The agency emphasizes that these substations are essential nodes of the network: they allow the voltage levels that feed the security and cooling systems to be transformed and maintained. Without them, plants cannot guarantee safe operation. One month depending on diesel generators. The situation in Zaporizhzhia is even more critical. According to an opinion column by Najmedin Meshkati, professor of engineering and international relations published in the Financial Timesthe plant spent a full month without outside power after its two main lines were cut. During that time it survived solely on diesel generators, a resource that the industry considers strictly temporary: they are designed to run for around 24 hours, not for weeks. Technicians were only able to repair the lines under the protection of localized ceasefires negotiated by the IAEA, according to NucNet. Even so, one of the two restored lines was disconnected again on November 14 due to the activation of a protection system. Grossi summed it up like this: “The electrical situation at the plant remains extremely fragile.” The condition for a shut down reactor to remain safe. Although Zaporizhzhia’s six reactors have been on cold shutdown for more than three years, the plant requires a constant three to four megawatts to maintain cooling pumps and other essential systems, according to Meshkati. The professor emphasizes that even huge emergency batteries require external electricity to stay charged. It is a vicious circle: without the electrical grid, batteries are used, but without external electricity, these batteries cannot be recharged and, without both, the cooling systems fail. And without cooling the risk of nuclear fuel melting or overheating increases. The University of Southern California professor warns that this scenario reproduces the conditions that transformed Fukushima into a global disaster: “What turned an earthquake into a catastrophe was the total failure of the electrical system.” And he adds that, unlike 2011 in Japan, this time the risk comes from deliberate human action. A network reduced to its minimum expression. Before the war, according to the Kyiv Independentthe Zaporizhia plant was connected through ten power lines. Today it only has one or two operations and has lost all connection ten times since the beginning of the invasion. The IAEA itself has described the situation power plant as “extremely precarious” and “clearly not sustainable” when it depends for long periods on diesel generators. Short and medium term risks. The notices in the last report on Ukraine by the IAEA point in the same direction: the main danger is not a Chernobyl-type explosion, but a prolonged cooling failure. This scenario could cause overheating of the reactors in cold shutdown, damage to the spent fuel pools and a possible localized or regional radioactive release, with the consequent need to create an exclusion zone in the heart of agricultural Europe. For its part, according to Meshkatiadds two other relevant elements. On the one hand, it points out that a serious accident will exceed the economic impact of Fukushima, estimated at about $500 billion. An incident of that magnitude would affect agriculture, transport, supply chains and the European insurance market. On the other hand, he maintains that if Russia manages to consolidate the precedent that an occupying army can take control of a nuclear power plant and connect it to its own network, the global nuclear security architecture would be seriously compromised. It would be a precedent without equivalent since the creation of international standards that regulate the civil use of atomic energy. Is there a meeting point? The IAEA has acted as an intermediary between Moscow and kyiv on multiple occasions. According to the Anadolu agencyGrossi traveled to Kaliningrad to meet with Likhachev, director of Rosatom, in order to directly discuss the situation in Zaporizhzhia and the minimum conditions to guarantee nuclear safety. At the same time, the agency is trying to technically shore up the Ukrainian electrical system. According to their own statementshas so far coordinated 174 deliveries of essential equipment – ​​switches, electrical cabinets, radiation monitoring stations, vehicles and computer equipment – ​​worth more than 20.5 million euros, intended to sustain nuclear security in Ukraine during the war. Nuclear security supported by fragile cables Europe breathes thanks to a handful of cables repaired under fire and diesel generators that have already proven to be well beyond their limits. As the Financial Times explainsthe continent’s security depends on electricity continuing to arrive and on the parties respecting the fragile ceasefires needed to repair lines when they go down. Grossi summed it up with a mix of relief and alarm after the restoration of one of the lines: “It is a good day for nuclear security, although the situation remains highly precarious.” And the precarious thing, in this case, is that a new attack, a mechanical failure or a downed line is enough to bring … Read more

A study analyzed the power of LED car headlights. The conclusion is what all drivers already know

by

I hate traveling at night, almost as much as drive in rain. It had been a while since I went to a national one, but a few days ago I had to do it and what had to happen happened: I was dazzled on more than one occasion. Car headlights have evolved tremendously in a short time and LEDs have prevailed in new vehicles. The problem is that every time there are more signs that we have gone too far with its evolution. And a new report puts a percentage on how dangerous they can be if they are not properly calibrated… or if the car that uses them is an SUV. In short. Whether because you have a new car or because you update the headlights of a car with a few years behind it, they are one of the elements that are most appreciated on the journeys. They see you better, you see better and it is one of the most important points in terms of safety behind the wheel. If the height is correct and they are well calibrated, they are a pleasure, but it can also happen that this is not the case and they dazzle or dazzle you. There, security goes to hell for a few seconds. The British Department for Transport has published the results of a study about glare caused by LED lights. Your conclusion? They represent a road safety problem, altering the habits of drivers in the United Kingdom. We could extrapolate it perfectly. Basically, between October 2024 and early 2025, they combined objective measurements in real conditions with surveys of 1,850 drivers. The results They are devastating: 97% of them affirm that they are frequently distracted, and 96% that glare from headlights is a road safety problem. Analysis. On the one hand, we have those statements from drivers, who were asked about the frequency with which they felt distracted due to glare from the headlights of vehicles traveling in the opposite direction. On the other hand, the objective analysis. To do this, the DfT used luminance cameras and mixed the data using a machine learning algorithm to identify the variables that come into play at high glare levels. They discovered that there was a strong correlation between higher luminance levels and reports of glare in some test vehicles (logical, on the other hand). Also that road factors influence, such as circular upwards or curves to the righttimes when drivers’ eyes are most exposed to the beam of light from the headlights. In the end, these are things that a study does not have to confirm if you have ever driven at night, but what is interesting about the study is the consequences and the “culprits.” Impact. For example, more than half of the respondents have affirmed that this discomfort due to glare has generated anxiety when driving at certain hours, which is why they have reduced night driving or have abandoned it altogether. And more than 20% point out that they would like to take the car less at night because of this, but they have no other option. According to statistics and beyond the indirect impact, they estimate that glare has bound about 290 accidents annually. and the effects They depend on age: a 50-year-old person takes nine seconds to recover from glare, while a 16-year-old takes just one second, which applies another risk factor on the road to older drivers. SUV. Beyond this, they have also found that larger vehicles, such as SUVs, are the most associated with glare in surveys. This is logical: they are taller, their headlights are more aligned with the eyes of drivers traveling in the opposite direction (especially in lower cars) and it seems that all new cars are SUVsso they are the ones with the most up-to-date lights. The problem of retrofit. This term in English refers to the modification of an existing component. In short: updating with new parts and superior technologies, such as changing the brakes for better ones, installing a new infotainment system or change the original halogen headlights for LED ones. You can buy new ‘bulbs’ even on Amazon and many are approved, but there are two problems: those that are not well regulated and those that are installed illegally. The British Administration has identified that illegal conversion is a problem, since changing halogen bulbs for LED means that those housings designed for halogen do not work the same with the new LED headlights, causing dangerous glare. British ITV has intensified its analysis of the sale of these kits, with heavy fines for violators. Not simple solutions. They estimate that around 800,000 vehicles fail their annual inspection due to headlight alignment problems, but although these are UK numbers, this is a global problem (in Spain22% of serious failures have to do with the lights) which implies that, perhaps, we have gone too far with the power of our cars’ headlights. The solution is not clear. The report recommends periodic glare checks and rethinking luminance measurements in modern headlights, but this will have to be studied. In the end, it is something that we all suffer at one time or another although, as they point Our colleagues at MotorPasión, for motorcyclists there is another added problem: reflections on the visor itself.

the 15% that shows who has the power

by

Apple has closed a deal with Tencent to charge a 15% commission on purchases within WeChat mini-games, half of what it usually charges, according to Bloomberg. After more than a year of negotiations, Apple accepts conditions that it would never have admitted in the West. Why is it important. WeChat It is not just another app: it is China’s unofficial operating system, with 1.41 billion monthly users. If Apple had blocked features or put too much pressure on Tencent, it risked a backlash that could have severely damaged its position in its third-largest market. Tencent I knew it. Apple too. 15% is the price the company pays to keep the peace in a market where it does not dictate the rules. The money trail. WeChat mini-games generated 32.3 billion yuan ($4.5 billion) in social media revenue in the last quarter alone for Tencent. Until now, Apple did not see a cent of that pie because developers avoided its payment system. With 15% on that basis, Apple could earn about $675 million annually if current rates are maintained. It seems like a lot, but it’s pocket change: Apple had a turnover of $383 billion last year. This deal doesn’t move the financial needle. Between the lines. The most striking thing is not how much Apple earns, but how much it has had to give up. In its global App Store, Apple takes 30% from most developers as a non-negotiable toll. In China, Tencent has forced you to accept half. The arithmetic speaks for itself: Apple has given up 50% of its potential revenue before even starting to charge. That is not “a trade agreement.” It is a recognition of who has the real bargaining power. Yes, but. Ultimately, for Apple, something is better than nothing. For years it has watched one of China’s fastest-growing digital entertainment segments develop entirely outside its payments ecosystem. The agreement opens a tap of income that did not exist before, even if it is a small tap. And it sets a worrying precedent: if the most powerful player in China gets a 50% discount, what will stop others from demanding the same in other markets? It will be a matter of negotiating strength. Not everyone has a market of 1.4 billion consumers. The contrast. In Europe and the United States, Apple has had to give ground due to regulatory pressure: antitrust lawsuits, digital market laws either court battles with Epic Games. In China, it has given way due to pure market reality. He has not needed a regulator to force him to lower the commission. It was enough for Tencent to sit down to negotiate knowing that it manages the digital infrastructure without which Apple cannot operate effectively in the country. The big question. Is this 15% the new standard for platforms with sufficient negotiating muscle, or can Apple manage to maintain it as a Chinese exception? What is clear is that the era of the universal 30% commission is over, replaced by a fragmented reality where whoever has the users dictates the conditions. It is another symptom of end of globalization as we knew it. In Xataka | Tim Cook promised them very happy expanding Apple thanks to China.
