problem

When the heat arrives, the boys fall in love, the solar panels have a fatal and Spain has a new electrical problem

by

Summer has arrived with excessive force To Spain. June has closed as the hottest month of which you have a record, and there is no indications that temperatures are going to give truce. The streets are emptied, public parks are deserted, and fans snort day and night as if trying to mark the rhythm of these unbearable days. But while life adapts as it can to this new heat, under the surface – where the invisible network that sustains modern life – heat has also tested the limits of the electrical system. High demand. While millions of people seek refuge under air conditioning, the Spanish electrical system begins to show saturation signals. Extreme heat triggers demand, reduces the efficiency of some sources of renewable generation and generates imbalances in the electricity grid. As collect the Iberian energy market operator (OMIE)on July 1, the price of the megavatio hour reached a peak of 167 euros at 9:00 p.m., an unusual figure for a night strip. The increase coincides with a high demand and a reduced renewable production at the end of the day, which forces the system to rely on more expensive technologies such as natural gas, According to Red Eléctrica España (REE). More heat, more network pressure. To all this is added an urban phenomenon that aggravates the pressure on the network: The island of heat. In cities, asphalt, concrete and lack of vegetation make the heat accumulated during the day stay overnight, raising the temperature several degrees with respect to rural areas. As a result, energy consumption does not descend after sunset, but is kept high for more hours. The households continue to light fans and air conditioning apparatus until well into the morning, which stress the system when the renewables have already fallen from the mix. But with more sun … The logical thing would be to think that with more sunny hours, Solar energy would suffice to meet the growing demand. And in part, it does: According to REE dataon July 1, renewables contributed 50.6 % of the electricity generated in Spain, compared to 49.4 % of non -renewable sources. But that daily average hides what happens in critical hours. From eight or nine in the afternoon, the photovoltaic disappears from the energy mix, just when the demand remains high and the temperature barely yields. At that time, they are the combined cycles – central that burn natural gas – that support the system, with more than 14,000 megawatts generated in some moments of that same night, According to REE data. There is an added problem. Solar does not always yield as expected: As we have already explainedpanels can have efficiency losses between 10 and 25% because of high temperatures. For each additional degree, they can lose up to 0.5 % yield. Nor does wind help too much: heat waves usually come accompanied by atmospheric stability situations that reduce the wind, which also lasts production. Will there be any blackout? Talking about generalized blackouts may seem exaggerated, but comparison with other countries, like the United Statesforces to take the threat seriously. However, the Spanish system has proven to have a certain margin of maneuver. After the blackout of April 28, they were activated Adjustment services to balance the network in case of collapse of the system at critical times. Although it avoids collapse, these mechanisms have a cost: they have more thanked the invoice part, especially for those in the PVPC rate. From that moment on, Ree has maintained an additional safety margin, operating with active backup power plants even when they are not in use, which structurally increases the operation of the system. Beyond the specific episode, that blackout exposed the deficiencies of a system that needs More storage, MicroRedes and greater local response capacity to disturbances. A system under stress. This summer is not only breaking temperature records: the margins of the electrical system is also testing. The combination of prolonged heat, night demand peaks and a more vulnerable renewable generation than expected is stressing the network at critical moments. The renewables are the present and the future, but they are not infallible. Its behavior also depends on the weather. And when the heat waves become the norm and not the exception, the resilience of the system depends on other factors: on the reinforcement of the networks, the storage, the demand management and, above all, to prepare the cities to resist without the most vulnerable paying the price.

Renfe has exploded the problem of the bird in full start of summer

by

The rail transport has started Julio, a month usually marked by vacation trips, from The worst forms Possible, with considerable chaos in one of its great arteries: the high speed corridor between Madrid and Andalusia. Trains stopped for hours. Delays Suspended services. And a monumental anger among the affected passengers joined to the one already showed in May, when Copper theft He collapsed the bird of Seville. What happened? That in the full start of July, with thousands of people making their bags to enjoy their summer vacation, the Spanish railway sector has encountered a considerable problem in one of its great arteries: the high -speed corridor between Madrid and Andalusia. And it is not the first. In early May the Madrid-Sevilla AVE line has already suffered A collapse which resulted in trains detained for hours, saturated stations and thousands of passengers (there was talk of more than 16,000) affected. Fault in a catenary. The notice jumped yesterday around the afternoon in the province of Toledo, where Adif recorded A fault in a catenary between the Yeles (Toledo) and La Sagra (southwest of the Community of Madrid). The problem, according to detailed in x The administrator of the railway infrastructure caused it a “lack of tension” that directly affected the high -speed trains that Madrid and Toledo connect with Andalusia. Click on the image to go to Tweet. An incidence with hangover. The chronicle of what has happened can be followed by a tweet. About half past nine of the Adif Night confirmed A “breakdown” in the catenaria (without going into details) that led him to mobilize technicians, displace relief locomotives to move the trains stopped outside the stations and even ask for help to the 112 of Castilla-La Mancha to attend affected travelers. At ten o’clock Adif confirmed that he had recovered the tension on one of the roads between the Sagra and Yeles, which partially unlocked the Madrid/Toledo-Andalucía corridor; But that solved only part of the problem. Adif itself acknowledged that the affected trains would continue to suffer delays by having to operate in a single route. Well, enter the morning, at 5.20 hhe chose to cut the tension to focus on the catenary that was still blocked and recover the second way from the yles to Mora. Checking the grill. The result was The suspension of the first -hour trains with origin Atocha and Destinad Andalucía and Toledo. “The difficulty of the rescue of two trains affected by the incidence and prolongation in the work to repair the catenary prevent the trains of the South Corridor with origin/destination Madrid and/or Sevilla circulating until new notice,” needed Almost at nine in the morning. The consequences They let themselves feel Also in long distance connections with Malaga, Granada, Cádiz and Huelva and Trains with Toledo, Puertollano and Ciudad Real. Click on the image to go to Tweet. “Delays can be recorded”. The message confirming that the catenary breakdown was repaired did not reach the eleven of this morning, which opened the door at the end of the trains of Madrid to the south and those that start from Andalusia and Castilla-La Mancha direction to the capital. Of course, the administrator of the railway infrastructure was cured in health with a clear warning for the passengers of the corridor: “Delays can be recorded due to the accumulation of trains.” “Absolute abandonment”. So far the Chronicle of Adif. The collapse in the railway corridor, however, left another very different story in networks, the one contributed by the passengers affected by the fault. “What seemed like a simple trip has become a nightmare: we have been trapped in the middle of a plain in Toledo, without electricity, without bathrooms, with an unbearable heat and surrounded by insects,” He denounced this morning An X user, Antonio Regalado, annoyed by the “absolute abandonment” of Renfe 5862. An evacuated octogenarian. “Thirteen trapped hours. This is not a delay, it is an abandonment”, insists Given. According to her testimony, a woman even suffered an arrhythmia and had to be evacuated in ambulance. “There are older people, children and passengers totally abandoned, with anxiety, hunger and without explanations.” 112 Castilla-La Mancha has confirmed In networks that of the five trains of the Madrid-Sevilla line damaged between the provinces of Toledo and Ciudad Real, four were able to continue the march during the night. The convoy located in Villaseca de la Sagra ran worse luck, so the 112 operators had to attend them at night. They also had to evacuate an old woman 84, who ended up being transferred to Toledo University Hospital for respiratory failure. The train did not resume its trip to Madrid until 9.30 a.m. Image | Pablo Nieto Abad (Flcikr) In Xataka | China wanted to be the queen of high -speed trains.

It is not you, it’s hotter than ever. And the problem is that summers are not going to improve over time

by

A good part of the planet is clear about one thing: it’s hota lot. So much that life during the day It makes complicated. Last June it became the New Julywhat leaves us a disturbing question now that we started new month: what will happen in July? Many wonder if what happens is “normal”, and the truth is that scientists have an answer: it is not only suffocating. Anticipated and prolonged. As we said, summer did not wait for July. With anticipated heat waves that have fried To Canada, the northeast of the United States, the United Kingdom, France, the Netherlands, and a good part of northern Europe, the 2025 summer season is being configured as another forceful evidence of the rapid advance of climate change. The pools in Toronto They remain open Until midnight, concerts are being canceled in Amsterdam and fans They have reappeared In French homes earlier than usual. The alarming is not just the heat intensitybut its chronology: the thermal threshold that previously marked the beginning of the warmest period of the northern hemisphere was reached around July 10. In 2024, the hottest year Never registered, it was exceeded from June 13 to September 5. This year, without being as extreme as the previous one, this weeks advanced regarding the historical average. The phenomenon reflects A clear pattern: summers are lengthening at both ends, starting before and ending later, which increases exposure to heat waves and elevates substantially The health risksagricultural and environmental. Heat out of time. I remembered The Washington Post That heat waves are no longer limited seasonal phenomena, but an increasingly continuous threat. According to data From the United States Environmental Protection Agency, its duration, frequency and intensity have increased significantly in the last seven decades, extending the “extreme heat season” of less than 50 days in the 90s to about 70 Since 2020. This phenomenon has altered the climate calendar in a drastic way: between January and mid -June of this year, 163 of 171 days registered temperatures greater than 32.2 ° C in extensive regions of the northern hemisphere, a figure unprecedented since 1980. Examples The consequences are manifested Multiple: anticipated forest fires, Early melting of glaciers in the Swiss Alps or the increase of deaths due to heat stroke, which in Europe have risen 30% In the last 20 years. The danger increases Especially in early heat waves, when the population has not yet adapted physiologically nor has preventive protocols activated, more seriously affecting older or vulnerable people. Heating accelerates. He underlined The New York Times That the evidence shows that the planet is heating, and is doing it faster than the models predicted just a few decades ago. The summer of 2025 had barely begun when the United States was already caught under that suffocating “heat dome” of The one we talk about who beat records, while Alaska registered his First official alert by high temperatures. As we said, these anomalies arrive after 2024 that was the warmer year Never registered, and reinforce what climate science has been anticipating: global warming caused by human activity not only continues its course, but also that It is accelerating. More science. A Recent study estimates that the average global temperature is increasing at the rate of 0.27 ° C per decadea significantly higher rate to the rhythm of 0.2 ° C that was observed in the 70s. But beyond the figures, the most disturbing is how these changes have begun to demonstrate directly And visible in everyday life: devastating floods, extreme droughts, increasingly voracious fires and heat waves that challenge the limits of the human body and modern infrastructure. The ends grow faster. In this way, each additional tenth not only adds heat to the planet, but also increased the violence of Meteorological phenomena extremes. According to the climatologist Daniel Swainevents such as torrential rains or forest fires do not grow in a straight line with the temperature: they do it with An exponential pattern. For each Celsius heating grade, extreme rainfall increases by 7%, but the so -called “record events” are doubling that rate. This intensification was not only predictable, but the scientists had already modeled it, although now it begins to feel tangible and disconcerting. Kate Marvel, another recognized climatologist, summarized it like this In the Times: “There is no climate out of climate change.” Phenomena like him Hurricane Helene or historical floods of Vermont They are not anomalies, but direct expressions of an altered atmosphere. Although a total understanding of the most extreme events is still lacking (in part because its rarity makes it difficult to Adjust your models urgently. Accelerated thaws. The impact of heating feels with special severity in vulnerable regions such as The Arctic and Antarctica. The thaw of his ice masses, which for decades seemed a distant phenomenon, is now contributing to a faster sea level rise than expected. A NASA analysis Posted in March revealed that the level of the oceans increased by 2024 to A higher rhythm to the estimated, due to the thermal expansion of the waters (heated in depth) and to the accelerated thaw of glaciers. The sea and the planet. In addition, the data from another study of the National Center for Earth Observation show that the marine surface temperature It is increasing above the previous forecasts, which has direct implications for The global climateprecipitation patterns and cyclones intensity. Cecilia Bitz, an expert in climatic modeling, acknowledges that simulating the complexity of the Earth is a challenge, but insists that the great physical principles of the climate system They are still valid: They are not being denied, but complying with disturbing accuracy. The energy imbalance. The physical root of global warming is in the Energy imbalance From the planet: the difference between the solar energy that the Earth receives and the one that returns to space. According to Another study Recent based on NASA satellite data, that imbalance It has doubled In the last two decades and is now … Read more

This city of China is the world epicenter of rare earths. The problem is that nobody thought of its inhabitants

by

To get an idea to what extent It has control Of those precious minerals that form the set of rare earths, the greatest enemy that China has is not outside its borders. It is such a monopolization in the sector that the danger has in “house” through of the smugglers. And of all enclaves, one stands out greatly as an epicenter of the entire heart. His name is Baotou, and everything that shines for the surrounding inhabitants is not gold. A normal city in appearance. Baotouan industrial core of 2.7 million inhabitants on the border with the Gobi desert, seems to the naked eye a second category Chinese city like so many others: shopping centers with western chains, local restaurants overflowing and children playing late. However, a short journey to the outskirts is enough to discover His true nature: A landscape dominated by factories, smoking chimneys and an environmental legacy forged by one of the most strategic and persecuted sectors of the planet. The heart of rare earths. Yes, the enclave houses More than 80% of the Rare reserves of China. Since in the 30s they were discovered in the nearby Mining District of Bayan Obo elements such as Cerio, Lantano or Samario, its exploitation has turned the city on a chain axis on global supply on industries such as electronics, automotive and defense. We have counted before: During the 90s, China increased its production by 450%, while other countries, such as the United States, They closed their mines. This concentration made Beijin the almost exclusive supplier of these critical metals, and today, in the midst of the commercial war with Washington, its control has been transformed In diplomatic weapon. Economy vs Human Cost. The problem? The Guardian told that mineral wealth has favored the economic development of Baotou, whose GDP per capita It widely exceeds the national average. However, prosperity has Your reverse: Processing plants generate toxic (often radioactive) waste that are discharged into huge artificial rafts. The most infamous, the Weikuang dam, for years was the largest landfill of rare earth waste on the planet, without adequate coating and directly close to the Yellow River. In fact, official reports have confirmed that these activities caused a 87% decrease of ammoniacal nitrogen in a tributary between 2020 and 2024, although accumulated ravages remain visible. Yin mountains on the outskirts Cancer and poison. For example, numerous studies They have documented devastating consequences in the health of nearby communities: from bone malformations to a “Epidemic” of cancer. Exposure to these elements, capable of crossing the blood brain barrier, has been associated with motor and sensory disabilities, as well as alterations in fetal neurological development. Not just that. 2020 investigations revealed that the dust of the streets contains concentrations so high that the children of Baotou and surroundings are exposed to dangerous levels Just to breathe. Daily particle ingestion rates in mining areas far exceed the limits considered safe. A washing … halfway. Given the growing international criticism, China has tried to clean its image. In 2022, state media announced that Weikuang’s dam had been transformed into an urban wetland, now supposed paradise of migratory birds. The reality? Explained the medium British that when arriving at the place, what one is located is a concrete wall that hides a dry and desolate lodazal. Behind, ruins of ancient “villages of cancer” and oxidized industrial structures extend. New homes built for displaced are practically empty, and foreign journalists are It usually blocks actively to prevent them from talking to residents. Rural sacrifice. So things, Baotou exemplifies an uncomfortable truth: the China domain In the rare earth market it has been possible not only for its geological reserves, but for a political decision where rural communities have been allowed to support Toxic costs of a globalized economic boom. It is not an exempt problem from China, of course, the same thing happens in other sectors such as AI and its data centers (we recently counted it with the Elon Musk Supercomputer). Be that as it may, and although there are less polluting technologies to process these metals, they are rarely used: its implementation would make the low costs that have cemented the Chinese position. If you want, in a context of growing international pressure and commercial sanctions, the extractive model It reveals both the fragility of environmental balance and the rawness of contemporary geostrategic priorities.

We have a big problem with AI agents: 70% of the time are wrong

by

The AI agents They fail more than a fair shotgun. That’s at least what reveals A recent study of researchers from the Carnegie Mellon University (CMU) and the University of Duke. These experts have analyzed the behavior of several of them and put them to the test to check if this is a “much noise and few nuts.” AND At the moment it is. Inspiration. Graham Neubig, professor of CMU, explained In The Register how inspiration had been A 2023 article of OpenAi. It talked about what types of work could be replaced by AI systems, but as he said “his methodology was basically asking Chatgpt if those works could be automated.” In that study they wanted to verify it by asking various AI agents to try to complete tasks that theoretically carry out professionals of those works. In Xataka Everything begins by asking a thing to an AI. When the AI ​​is asked for others, chaos begins Theagentcompany. To carry out their study, the researchers created a fictitious company they called The Agent Company and they used it so that different agricultural models tried to complete various tasks. These systems should be able to use access to several services such as Gitlab, Owncloud or Rocketchat to carry out these works, but their performance was disappointing. 70% errors. The researchers used two trial environments called Openhands Codeact and Owl-Roleplay and in them they were testing the most important AI models today. The best of all of them is Claude Sonnet 4, which managed to solve 33.1% of the proposed tasks. Behind are Claude 3.7 Sonnet (30.9%), Gemini 2.5 Pro (30.3%) and, much further, disastrous GPT-4O (8.6%), call-3.1-405b (7.4%), QWEN-2.5-72B (5.7%) or Amazon Nova Pro V1.0 (1.7%). In the best case the models can complete 30% of the requested tasks, but they fail in 70%. Or what is the same: a lot of noise and few nuts according to these benchmarks. Unable agents. During these tests the researchers observed various types of failure in these tasks processes. Thus, there were agents refusing to send a message to colleagues who were part of the task, there were also agents unable to manage popup windows during navigation sessions, and even agents who cheated or cheated. In one of the cases, they highlighted, an agent who had to consult a person in Rocketchat (an alternative Open Source a Slack) did not find it, so “he changed the name to another user to give him the user with whom he had to contact.” But they are improving. Even with those problems, the evolution is being positive in the performance of these AI agents. Neubig and his team tested a software agent that was able to solve about 24% of the tasks involved web navigation, programming and some related tasks. Six months later they tested a new version and achieved 34% of completed tasks. {“Videid”: “X8HJ0VY”, “Autoplay”: False, “Title”: “Chatgpt: What you did not know what you could do | tricks”, “Tag”: “”, “Duration”: “790”} Imperfect but useful. Not only that: these researchers pointed out that even failing so much, AI agents can remain useful. In certain contexts, such as programming, a partial code suggestion with which to solve a certain fragment of a program can end up being the basis of a solution in which the developer can then work. Care where you use them. But of course, agents make so many mistakes can be a problem in scenarios more sensitive to these problems. Thus, if we commission an agent who writes Correos and sends them to incorrect people, the result could be a disaster. There are solutions in sight, such as the growing adoption of Model Context protocol (MCP) that facilitates the interaction between services and AI models so that communication is much more precise and these errors can be mitigated during the autonomous execution of tasks. A benchmark that makes the AI ​​models look bad. For this expert one of the great disappointments is that companies that develop AI models do not seem interested in using it as a metric to improve their developments. Neubig suspected that “perhaps it is too difficult and makes them look bad.” It is something similar to what happens With the benchmark arc -ag2: It is such a difficult test for the IAS that today The best of all models of which they try to overcome it is o3, which achieves – a 3% of completed tasks. In Salesforce they coincide. That previous study is complemented With another realized by a group of Salesforce researchers. They created their own benchmark specifically aimed at verifying how various AI models would be checked when controlling typical tasks in a CRM like those developed by the firm. His project, called Crmarena-Pro, tests those AI agents in areas such as the Sales or Support Department. In Xataka If the question is whether IA is already as good as human intelligence, the answer is: solves this puzzle To replace workers, nothing. In their conclusions, these researchers reveal how the AI ​​models “achieve globally modest success rates, typically around 58% in scenarios with a single shift (execution), but with the yield significantly degrading approximately 35% in multiturn scenarios.” In fact, they explained, “agents are not generally prepared or have the essential qualifications for complex tasks.” The risk of some experts, with A great impact of AI on various jobsit seems precipitated. A complicated future. To these discreet results, the prediction of the Gartner consultant is joined. According to your studiesmore than 40% of the development agents projects will end up being canceled at the end of 2027. The main person responsible for the report, Anushree Verma, indicated that “at present, most of the agricultural projects are experiments or tests of concept in the initial phase, mainly driven by advertising already often badly applied.” The message is clear: there are too many expectations in relation to AI agents, but the current state of technology shows that today its application is problematic and limited.

In Brazil there is a fever for babies. The problem is that they are so real that people are confusing them

by

The story began as a harmless content in Tiktok, one that quickly climbed to became a national issue in Brazil. A young woman He published a video In which he pretended to take his “baby” Bento to the hospital: he prepared his backpack, lying it in the car, weighed it, gave him the bottle and cleaned his cheek. More than 16 million people saw that scene, but few realized that he was not a baby, it was A Reborn doll. Political chaos. I told this week The Guardian. While Jair Bolsonaro faces a trial for I attempt at once of state and the current president Lula is going through The worst moment of popularity of his third term, the focus of wide sectors of the Brazilian public debate It has diverted Towards an unusual phenomenon: Reborn dolls. We talk about figures Baby hyperrealistscollected and made by thousands of people (mostly women) in Brazil for decades, who have suddenly become white of viral teasingviolent threats and an unusual legislative wave. Laws against dolls. According to The New York Timescurrently there are at least 30 legislative projects presented in Brazil to prevent Reborn dolls from accessing public services such as health or education. Legislators on the right, especially in the state of Amazonas, have even taken Dolls to Parliament claiming that some women are trying to obtain public benefits with them, (although there is no evidence to support it). In a turn of the events that approaches a dystopia, one of the drivers even asked if the next step would be to castrate “Reborn dolls” in veterinarians. Stigmatization As a mockery, the official account of the city of Curitiba warned To the “Mothers Reborn” that their dolls do not give the right to use yellow seats reserved for pregnant women on buses. In contrast, the Municipal Council of Rio de Janeiro proposed to establish On September 4 as the day of the storker Reborn to honor the artists who manufacture them, although the mayor He vetoed the measure on the argument that “this is not happening.” To put things in order, or almost, According to the UOL mediait has only been documented A real case of a woman with a psychiatric disorder who tried to enter a hospital with a doll, which shows that most bills are based on viral fictions. Vinyl body kit From Tiktok to Congress. As we said at the beginning, it all started with a series of virals in networks where a collector had called “Crazy” for taking his doll to a mall. Then, another clip showed a doll being Attended in a hospitalas part of a role -playing game. Although the author of the video clarified that it was A dramatizationthe content was replicated alarmistly as if it were real. From there, social networks exploded with teasing, threats and a torrent of indignation aimed at the so -called “mams reborn.” The controversy reached a disturbing point on June 6, when a man assaulted a real baby four months on public roads by confusing it with one of these dolls. The aggressor was released on bail and the baby is out of danger, but the fact illustrates the climate of hysteria unleashed. Disguised misogyny. What at first glance seems like a lower controversy over eccentric hobbies hides a darker background: the pathologization of female entertainment. It counted at the Guardian The sociologist and political scientist Isabela Kalil, professor at the FESPSP, who warns that while adult men can collect action figures or spend hours in front of video games without raising suspicions, women who interact with hyperrealistic dolls are quickly tildos of unbalanced. The artist Larissa Vedolinknown as Emily Reborn In networks, he has received death threats daily for sharing his creations. “They write to me from anonymous accounts who are looking forward to finding me on the street with a weapon,” He recounts. Vedolin, like many other creators and collectors, defends that the Reborn are not toys, but works of art. Some may take weeks to complete and reach prices of up to 3,000 eurosdepending on the level of detail, such as the width hair implant. Social reflection. He Youtuber Chico Barneywho recorded a collector event in São Paulo for Your documentary Reborn Babies Don’t Cry, He pointed out With surprise the normality of the meeting: “It was only a group of people sharing an interest, with nothing eccentric.” But that contrast between the reality of the phenomenon and the viral narrative highlights a frequent dynamic in contemporary digital culture: the constant search for a target for collective hatred. Kalil summarized it rarely: the fury is not based on real events, but on a need for channel social anxiety through symbolic objects. “This case has served to project contempt, mockery and aggression against women who deviate minimally from conventional expectations,” affirms. Ancient practice. The Times remembered that Reborn dolls exist Since the 90s and his interest is not limited to Brazil. In the United States, Dave Stack, founder of Reborns (an online sales platform) ensures that sales have grown up constantly: 10 dolls a day five years ago between 40 and 60 currently. Prices range Between 200 and 250 dollars For vinyl models, and up to more than 4,000 for limited editions of soft silicone. Among its buyers there are mothers who They have lost childrencenters for patients with dementia, lawyers who use them in judgments, creators for film and television, and mainly people who “simply love babies.” Some clients even take them to medical consultationsThey feed them with porridge or photograph them with Santa Claus. A hysteria as radiography. In summary, the Reborn phenomenon in Brazil has become the closest thing to A mirror of collective anxiety, normalized misogyny and the excessive influence of social networks in political discourse. What is essence is a form of artistic expression or an emotional refuge has been transformed in whitewashing, legislation and polarization. The episode reveals not only the ease with which a moral panic is generated, but … Read more

There are so many people growing marijuana in their homes that Endesa has a problem. And it will solve it with ia

by

In the industrial areas of many towns or cities, the constant buzzing of high pressure lamps illuminates hundreds of marijuana plants that grow to the rhythm of stolen electricity. It is a scenario that is repeated daily throughout Spain, where illegal cannabis cultivation and electric fraud They have woven a network of silent crime. Faced with this threat, Endesa has taken another step. Root cut. Endesa and the General Police Station of the National Police have signed a collaboration protocol to strengthen the fight against crimes that affect the electricity supply. From the massive electricity fraud to the theft of material, sabotages and even cyberators, as collects the press release. A more joint action. The protocol foresees, among other measures, joint training, information exchange, analytical reports, technical field advice. In addition, it contemplates the active participation of the Judicial Police in technical actions of Endesa and addresses associated crimes such as the manipulation of measuring equipment, the theft of personal data or scams to consumers by cybercriminals. A problem that does not stop growing. According to the European drug report 2025, Spain concentrate 73% Of all the seizures of marijuana in the EU, many of them in plantations Indoor connected fraudulently to the network. Only in the last year, the Endesa networks subsidiary, e-distribution, disconnected 2,214 illegal hooks related to crops, with a consumption equivalent to 70,000 homes. The data is replicated in different areas of the country. In Granada, like has detailed ABC Granada, between January and April of this year, Endesa has detected 246 illegal plantations, at the rate of two a day. In Córdoba, in the same period, 19 files have been opened, which is equivalent to one per week, According to the Córdoba Diario. In both cases, the excessive consumption – quoted to the up to 80 homes by plantation – saturates the network and causes collateral damage. The highest invoice. The impact goes far beyond the economic. These illegal connections cause constant overloads, with serious safety consequences. Last summer, 24 fires were recorded in the distribution network in Andalusia, five of them in Granada and four in Córdoba, directly linked to marijuana plantations, According to the Córdoba Diario. Technology at the service of prevention. To deal with this challenge, Endesa has opted for prevention. For years, predictive models based on artificial intelligence and Big Data have applied to detect suspicious patterns. Now, it has also begun to display smart sensors in its networks, capable of anticipating overloads before they occur. A battle without rest. Electric fraud linked to illegal marijuana culture not only challenges electricity, but also the coexistence model in many areas of the country. The answer is already underway, but the challenge – technical, police and social – has just begun.

There are people eating carrots like rabbits because they think that they will get morenos. There is only a small problem

by

Summer arrives and with it, the trick of tricks to get that golden tone that leaves the mark of a good vacation. Between sunscreens, self -lane and calculated sun exposure, there is a advice that resurfaces every year as if it were a novelty, although it has been circling in beach conversations decades, Fashion magazines and now, Viral Videos of Tiktok: “Eat carrots and you will get brunette.” But is there anything true in all this? A harmless snack? Eating carrots on the beach is not something so crazy, since they are fresh and nutritious. However, the old belief that, if you feed like a rabbit, you will end with golden skin as if you had been in Menorca, every summer returns. The point is that the color differs much from what one can imagine. A rather orange tan. What is really happening is a phenomenon known as Carotenodermia. “Yes, carrots can change the color of the skin,” has affirmed for glamor Dermatologist Dr. Christian Merkel. But, he has warned: “The tone tends more to orange than to the classic brown of the solar tan.” This effect is due to beta-carotene, a pigment present in carrots, pumpkins, mangoes and other warm fruits and vegetables. When consumed in large quantities, this accumulates in the skin, especially in areas such as palms of the hands, soles of the feet, elbows or nose, causing a change of color in the skin. A false brown. And not even. Dermatologist Silvija Gottesman, Interviewed by MedPage Todayhe clarified: “It is not a true tan, since unlike the tone generated by melanin after sun exposure, what is achieved with carrot is a superficial coloration, without activation of melanocytes.” So, more than a golden tan, it is a temporary orange dye. There is a stop. Like almost everything in nutrition, the dose matters. Sarah Carolides, nutritionist of the Lanserhof Clinic, He explained for Women’s Health Mag That excessive consumption of beta -carotene can dye the tpiel, even without realizing it. He estimates that it is enough with about 12 raw medium carrots per day, or less than 300ml of daily juice for approximately one month, to begin to notice visible changes in skin color. In a documented clinical case by the University Clinical Hospital of Zaragoza, a One year girl who developed a notable yellowish coloration after consuming carrot puree daily. The pigmentation disappeared after removing the food from the diet for two months. Can you entail a danger? In general, no. Carotenodermia due to food is not harmful and is usually reversed when modifying the diet. However, attention must be paid because it can be confused with diseases such as jaundice. In addition, in people with metabolic disorders or diseases such as hypothyroidism, diabetes or anorexia nervosa, this type of pigmentation could indicate more serious imbalances. As has pointed out The doctor of Lucas Laguna for Consalud, the accumulation of carotenes is not only because of the diet, but for alterations in his metabolism and elimination. The end point. Eating carrots have benefits. They are healthy, antioxidants, rich in vitamin A and can give a slight warm tone to the skin. But no, you’re not going to tan eating as Bunny Bugs. The effect is more orange than gold, more visible in the hands than in the face, and more anecdotal than aesthetic.

The two most important chip companies in China have a problem: the 5 Nm have been choked

by

In the middle of last May Dr. Kiman expert in the manufacture of integrated circuits who has worked in Samsung and who currently investigates for TSMC in the US SMIC (Semiconductor manufacturing international corp) I was about to Start 5 nm chips production. And also that he planned to launch his first 3 Nm nodes equipped with GAA transistors (Gate-alall-around) in 2026. This company is the largest Chinese manufacturer of semiconductors, and has been working on the development of its own 5 Nm photolithography with Huawei. For these two companies to have the ability to manufacture their own 5 Nm chips is crucial, but they are having serious problems with this integration technology. Dr. Kim pointed in May that the performance by wafer that SMIC had reached in this node was less than 30%, but now there are two antagonistic means, the Canadian platform Techinsights and the Chinese newspaper SCMPthose that support the difficulties faced by Huawei and SMIC. According to Techinsights the new laptop Matebook Fold Ultimate Design Huawei incorporates a soc Kirin X90 manufactured by SMIC. Nothing striking here. What is surprising is that the chip of this ambitious team is not produced in the 5 Nm node. SMIC is manufacturing it in its second -generation 7 NM node (N+2) using an integrated circuit production technique known as Multiple patterning. This strategy in broad strokes consists in transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. China needs avant -garde lithographs, but endures thanks to mature chips The problem facing SMIC and Huawei, as we have explained in other articles, is that the Multiple patterning It has an upward impact on the cost of chips and the decrease in production capacity. These two Chinese companies have been forced to use this technique in their equipment deep ultraviolet lithography (UVP) because the prohibitions of the United States and the Netherlands prevent the Dutch company Asml from selling their machine their machines in Chinese extreme ultraviolet photolithography (UVE). The latter allow to produce more advanced semiconductors than UVP equipment. In Xataka The cure of some diseases "incurable" is already closer thanks to quantum computers According to Techinsightts, the new Matebook Fold Ultimate Design Matebook of Huawei incorporates a SOC Kirin X90 manufactured by SMIC In current circumstances it is reasonable to conclude that Huawei has not yet incorporated 5 Nm chips manufactured by SMIC in its most advanced equipment because the production of these integrated circuits is still very limited. This is what Techinsight and SCMP supports. And we think about it too. However, there is something important that we should not ignore. As I mentioned a few lines above, China needs avant -garde photolithographies To have the ability to make chips as advanced as those produced by South Korean companies Samsung or SK Hynix, Taiwanese TSMC or Intel or Micron Technology Americans. But, curiously, the Chinese semiconductor industry is surviving Thanks to mature chips. In fact, in 2024 it produced 12.5% ​​more than in 2023. It is not bad at all, especially if we are in mind that US sanctions and their allies prevent Chinese manufacturers of integrated circuits accessing UVE lithography equipment. And since 2024 they cannot buy more UVP lithography machines. For a good part of 2022 the production of China semiconductors suffered an important fall and did not begin to recover until the end of that same year. Of course, in 2023 this industry grew almost constantly, and in 2024, as we have just seen, the rebound was monumental, especially in the final stretch of the year. {“Videid”: “X81Felr”, “Autoplay”: False, “Title”: “A future without mole in China the industry changes the paradigm and we explain why”, “Tag”: “”, “Duration”: “182”} In this situation it is reasonable that we ask ourselves what kind are the integrated circuits that are producing the Chinese manufacturers. And the answer is very revealing: these are chips derived from mature integration technologiesusually of 28 nm or less advanced. After all, the semiconductors that we find mostly on electronic devices, appliances or cars, among other products, have been produced using them. More information | Techinsights | SCMP In Xataka | The US has declared the total war on Huawei: he does not want him to sell his chips for the most advanced outside of China (Function () {Window._js_modules = Window._js_modules || {}; var headelement = document.getelegsbytagname (‘head’) (0); if (_js_modules.instagram) {var instagramscript = Document.Createlement (‘script’); }}) (); – The news The two most important chip companies in China have a problem: the 5 Nm have been choked It was originally posted in Xataka by Juan Carlos López .

In case not finding waiters were not enough, the hospitality faces a new problem this summer: where to accommodate them

by

According to a recent report Prepared by Obsbusiness School, tourism represents 15.2% of the total of the national economy and 2025 has all the signs of becoming a year of record for this sector, with an estimate of 98 million tourists, which represents an increase of 4% compared to last year. These tourists will spend about 138.5 billion euros. The data from the Ministry of Industry and Tourism They pointthat the sector will use a total of 2.99 million people. Such and as they highlight in Five daysthe main problem facing the hotel sector is not just the Personnel shortage. Is that, although they can hire workers to cover the high season in summer, these They cannot be paid The accommodation by the High price of rentals In tourist areas. Homemade. According to the last ‘Rent prices report in Spain’ Published by Idealista, the average price in Spain is 14.5 euros per square meter. That is, a 60 square meter accommodation should cost about 870 euros. However, the price increases when we approach tourist areas such as Málaga (16.3 euros/m2), Balearic Islands (19.7 euros/m2), Barcelona (23.9 euros/m2). In the case of the Balearic Islands, for example, the rent of a 60 -square -meter house would amount to 1,182 euros, a figure that can be doubled in high summer season. The high price of rentals makes it unfeasible that workers from other territories move to the main tourist destinations during the months of greater influx because, literally, The salary is gone Only in the rent. Work and accommodation. The hoteliers of the Balearic Islands were the first to alert the situation. Hotel chains Meliá, Riu, Barceló and Iberostar had planned increase your templates To meet summer demand. Due to the difficulty of finding accommodation for their new employees, chains have been forced to reserve a part of their facilities as accommodation during the summer months, offering it for free as an incentive to attract qualified talent. Hospitality entrepreneurs in the Canary Islands, meanwhile, They offered to build homes at priced price to rent to workers in the sector. However, the Ministry of Tourism estimates that only about 455,000 employees work in these large chains that have enough financial muscle to assume the cost of the accommodation of its employees. The other 2.5 million remaining employees belong to restaurants, bars and other small businesses. That leaves them with a serious problem, no longer due to lack of labor, but because rental price It makes someone from outside move during the high season to work. The only way out: adapt. It is materially impossible that the supply of local labor covers all the demand for the hospitality during the high season, so, given the impossibility of hiring more personnel, restaurants and small hospitality businesses of those those Tourism areas “Tensioning“They have chosen to adapt and reduce their care schedule depending on their staff. According The data of the Turijobs Employment Portal published by Self -employed and entrepreneurs87% of restoration businesses have had to apply these time adjustment measures to adapt to the lack of personnel. Desestationalization of tourism. One of the objectives of the tourism sector is Destationalize itTo, thus stabilize demand throughout the year allowing a more rest and economic continuity market, instead of focusing all the activity in the summer months. As they highlight in The countrypart of that goal is being achieved, and during the first three months of 2025 it has been increased by 5.7% The number of tourists, so that the tourist season is now ahead of May and ends beyond October. The de -stationalization of tourism would allow employees to settle in these destinations throughout the year, not only during the summer months, stabilizing in turn the availability of a sufficient local workforce. Long -term strategies. Given an unlikely scenario of moderation in rental prices, the most affected companies in the sector have adopted a long -term local personnel collection strategy. Thus, the dependency of personnel from other autonomies is reduced and, with it, the problem of accommodation. Portaventura World and University Rovira and Virgili signed a training agreement In 2024 for 150 employees per year. This agreement offers, in addition to a training accreditation, a job at the facilities and the Tourist Resort of Port Aventura once the training is finished. In the same line the initiative of the hotel chain THB Hotels moves that, through Your program THB College has offered accommodation and training to more than 2,000 employees since its creation in 2014, eliminating the problem of the shortage of qualified and accommodation personnel for them.
