suspect

College students are getting more A’s than at any other time in history. There is a suspect

by

Some already call it “grade inflation.” It is a phenomenon that should make us happy—what grades our young people get—but that is increasingly worrying in the educational world. University students have never gotten as many A’s as they have until now, but in reality the credit is not theirs. Using ChatGPT and other AI tools It is distorting its capacity and putting the educational system at a global level in check (again). Note inflation. Igor Chirikov published in May 2026 a study in which he talked precisely about how artificial intelligence is causing grade inflation. In his research, he analyzed the data of half a million students in 319 subjects at the University of Texas, and detected something surprising: since 2022, when OpenAI launched ChatGPT, the number of outstanding students at that institution has grown by 30%. But not everyone gets the same grade. In his conclusions, Chirikov explained how “these increases” in the grade “were greater when homework had a greater influence on the grades, which is consistent with the theory that AI is replacing the student’s work, and not improving learning.” The effect is greater, for example, in courses such as Economics or Journalism, where there are many written assignments to be submitted, but also in Computer Science courses and others in which programming subjects are taught. Both ChatGPT and other AI models are an increasingly popular (and effective) tool for students who want to improve their grades at all costs. perfect homework. The researchers indicate that a displacement of cognitive tasks is occurring here. The student no longer uses technology to support the learning process, but rather completely delegates many of the tasks that he should do to the AI. Essays, research papers and programming practices What should they give to teachers? They are becoming more and more perfect. Mirage. That theoretical brilliance is a mirage. Controlled studies like this one reveal that students who systematically use AI in their assignments end up suffering a 17% drop in their grades when they are subjected to a classic in-person pencil and paper exam on the same subject. ChatGPT becomes a superpower, but without it, grades drop clearly. The problems grow. Grade inflation is not a new phenomenon. In the US, university centers suffer structural pressures: if they are strict, they receive criticism from students, which jeopardizes future students wanting to attend them. This contributed to the fact that at Harvard, for example, A’s went from representing 24% of grades in 2005 to 60.2% in the spring of 2025. ChatGPT, write me my TFG. In Spain and Europe the panorama is similar. 89% of university students admit to using AI to write reports or Final Degree Projects (TFG), according to a recent GoStudent survey. Meanwhile, 61% of teachers confess that they do not have tools or software to confirm that whoever has done a job has not done it with AI. They are all too good students. When the outstanding becomes something totally normal and so frequent, this grade loses its power of differentiation. The filter previously made it clear which students were exceptional, something that was also vital for companies’ search for talent. Now those looking for these talents have reacted: in the US, job portals such as HandShake show that job offers that require a minimum GPA (average score of the university degree) of 3.5 out of 4 have skyrocketed from 9% in 2020 to 25% in 2026. As all university students are exceptional, companies look for the most exceptional among the exceptional. No more A’s. This distrust of job and homework qualifications has made some institutions prefer to return to the past. harvard will apply a notable reform in fall 2027 and will limit outstanding grades to a maximum of 20% per course, while honors enrollment will also depend on a certain percentile instead of via grades. 85% of the students opposed to these measures, but at Harvard they will continue with the measures although they indicate that they will review their application three years after the start of their application. everyone cheats. At the prestigious Princeton University the phenomenon is equally worrying. About half of its students They used AI to write their essays. 15% admitted to using AI to cheat in school, and 65.5% “knew a classmate was cheating and did not report it.” Everyone seems to be cheating at the university, as indicated in an article in The New York Intelligencer as early as May 2025. The university has just approved a proposal that would allow supervised exams, something that would break a 133-year tradition in which the students themselves monitored each other to prevent others from cheating. The “Code of Honor” of this institution has not been able to with the avalanche of AI.

The wealth gap between young and old in Spain is skyrocketing and we have a suspect: housing

by

Just look at the list of greatest fortunes in Spain of the last two years to realize that not only have their assets grown, but even among the wealthiest a gap has been created increasing among the rich and ultra-rich. This wealth gap is not an isolated phenomenon among the richest 1%, but rather has permeated to the entire population, leaving a worrying generational scar to which they have already put a figure: 340,000 euros. That is the difference in assets that today separates a person under 35 years old from someone who is between 65 and 74, according to a report which has just been published by the Santalucía Institute. A generation that starts from scratch. The data from the report maintain that the median wealth of those under 35 years of age in Spain has plummeted by 76.7% in the last 18 years. Not only do they accumulate fewer assets than their parents at the same age, but a growing proportion of young people “lack significant assets, which limits their financial stability and their ability to undertake long-term vital projects,” the report notes. The participation of young people under 35 years of age in the country’s total net wealth went from representing around 8.2% of the national wealth in 2002 to just 2.1% in 2022. For their part, those over 75 years of age, in the same period, went from representing 8.3% of total wealth to 18.3% in 2022. wealth transfer that has been redesigning the economic map of the country. This means that, although the net wealth of Spanish households has grown by 80.9% in the last two decades, this growth has mainly benefited those who already had a certain initial wealth, making the balance of wealth growth lean more towards the older (and more wealthy) population. The brick that only rose for a few. The report from the Santalucía Institute assures that the heritage in Spain rests almost completely in the homethus explaining the origin of the wealth growth of the oldest segment of the population. More than 80% of household assets are real estate. That has favored those who bought properties when prices were affordable. Those that came laterToday’s young people have found a market where buying a home is little less than a utopia. The property rate among those under 35 years of age has fallen from 35% in 2023 to 30% in 2025, continuing with a clear downward trend. Without home ownership and with skyrocketing rents At historic highs, the assets of young people have no basis on which to grow. Added to this is the job insecurity that characterizes this age group, which further reduces their savings capacity, closing a circle of which it is increasingly difficult to escape. The generation gap in figures. According to data from the ‘Family Financial Survey‘ conducted by the Bank of Spain, the gap between generations reached its historical maximum in 2022 and rose an additional 3% in 2024, the last year for which the entity’s data is collected. People between 65 and 74 years old accumulate on average more than 425,000 euros in deposits, investments and real estate assets, compared to the 83,000 euros that, on average, those under 35 have available. The distance between generations, estimated at 340,000 euros, has never been so great. Beyond the gap between generations, a report Prepared by FEDEA economists based on data from the Bank of Spain, it confirms that wealth inequality in Spain has grown constantly in the last two decades. The richest 1% concentrates around 21% of the country’s total wealth, while the poorest half barely reaches 7%. The Gini index, which measures this inequality, has risen from 0.57 in 2002 to 0.69 in 2022. Income also distances. The problem for the youngest is not only the accumulated wealth, but also in the income they receive every month. The median income of households between 65 and 74 years old already reaches 34,700 euros per year, this is 2,700 euros above what households headed by those under 35 years of age earn. The most striking thing is the speed at which this change has occurred since, in 2022, that difference was just 500 euros per year, but in just four years that difference has multiplied by five. Young households already have 8% less income than older households. Less income, less savings, less assets. The Santalucia Institute report, just as the OECD for yearswarns that this model points to structural inequality that will have direct implications for housing, the ability to save (and consume), and the redistribution of wealth.

The United Kingdom has just activated an unprecedented air mission over a lost island in the Atlantic. There is a hantavirus suspect

by

In 1961, a nurse had to be urgently evacuated from Tristan da Cunha after a volcanic eruption forced completely vacate to the entire population of the remote island. For weeks, that small territory lost in the middle of the Atlantic remembered something that remains true today: when an emergency occurs there, arriving on time can become an extremely complicated operation even for a country like the United Kingdom. The forgotten island of the Atlantic. While dozens of passengers from the MV Hondius cruise They began to disembark in Tenerife between health checks and repatriation flights for a hantavirus outbreakmuch further south and far from the cameras, the United Kingdom has started an operation completely different on an island that almost no one would know how to locate on a map. Tristan da Cunha, considered the most remote inhabited island on the planet, has suddenly become the scene of a unprecedented air mission for British forces after a british citizen showed symptoms compatible with hantavirus after leaving MV Hondius. With just 221 inhabitants, no airport and almost a week by boat from the nearest major port in South Africa, the island was caught in an extremely delicate situation when oxygen reserves began to run out and the small local medical system found itself unable to face the risk of contagion and isolation alone. An unprecedented military mission. The British response was as extraordinary as the place where he was to be executed. The Royal Air Force mobilized an Airbus A400M Atlas from RAF Brize Norton accompanied by a Voyager tanker plane to carry paratroopers, doctors and tons of medical supplies to the middle of the Atlantic. There was no possible landing strip, so the United Kingdom took a unprecedented decision: drop military doctors by parachute over the island. Six members of the 16 Air Assault Brigade They jumped alongside a doctor and an intensive care nurse in an extremely complex operation marked by strong winds and a minimal margin for error. The jump was made practically over the ocean before to correct the trajectory towards the island, with the real risk of ending up falling directly into the Atlantic if something went wrong. Never before have British forces deployed medical personnel by parachute drop on a humanitarian mission of this type. Medical supplies were dropped on the remote island, which has no landing strip and has a population of just 221. The cruise ship that took the problem to the middle of the ocean. It all began weeks before aboard the MV Hondius, the expedition cruise ship that was sailing through the South Atlantic when it appeared a hantavirus outbreak which would end up leaving several dead and multiple confirmed cases. The case has been of particular concern because the identified variant belonged to the Andean strain, one of the few capable of be transmitted between people. Apparently, the British citizen who ended up isolated in Tristan da Cunha had abandoned ship mid April and began to develop symptoms days later on an island that, as we said, does not have advanced hospital capacity and is normally cared for by just two medical professionals. While some passengers were treated in the Netherlands or South Africa and others were isolated in the United Kingdom After returning from Tenerife, the British health authorities quickly understood that the real problem was no longer on the cruise ship, but in that small isolated community in the middle of the ocean where any worsening could turn into a emergency impossible to manage with conventional means. Geography as a threat. Plus: the operation revealed the extent to which geography continues to condition even to countries with enormous military capabilities. Tristan da Cunha has no airport, no regular air routes and its sea connections are extremely slow and limited. Simply evacuating paratroopers and medics after the mission will require a complex maritime operation carefully planned due to health risk. I was counting a few hours ago BBC that the jump was not made over a large open space either, but rather over a small island buffeted by winds that usually exceed 40 kilometers per hour. The soldiers, in fact, ended up landing at the local golf course while the island’s inhabitants improvised receiving medical equipment and unloading more than three tons of supplies for the hospital. All this to contain a possible contagion in a territory where any logistical failure can take days to correct. The unknown Atlantic. If you will, history also reveals an uncomfortable reality about major modern health and geopolitical crises: almost all the attention tends to be focused on in visible places and connected while huge peripheral spaces remain out of focus until an emergency breaks out. Thus, while the media focus has followed the arrival of the cruise ship to the Canary Islands minute by minute, the hantavirus has ended up activating parachute dropsmilitary doctors and extreme logistical operations on Tristan da Cunha, a place so remote that even a relatively small health emergency forced resources to be mobilized normally associated with war scenarios or major catastrophes.

Suddenly, all the papers students hand in at universities look like the same job. There is a suspect

by

AI has caused an earthquake in the education sector. Students use it (many times indiscriminately) and teachers try to adapt to the change reinventing homework and exams. As the years go by, its use becomes normalized and the effects are already beginning to be seen. One of them is that all students They’re starting to sound the same. When AI gives its opinion for you. They tell it in cnn. AI chatbots have become another everyday tool in university life, but it is not only that they are used as support to write a paper, there are more and more students who turn to AI for everything, even to know what to say in class. They tell the case of a Yale student who admits that during a class debate “the conversation stopped, I looked to my left and saw someone frantically typing on their laptop.” He was asking a chatbot the same question his teacher had just asked. I myself am doing a university master’s degree and the situation is not strange to me. There are many students who turn to a chatbot to answer questions that are precisely looking for a critical and personal answer. Homogeneous thinking. It is one of the consequences that are being seen as a result of the use of AI chatbots. According to a study published in March of this yearLLMs narrow the diversity of human expression in three dimensions: language, perspective, and reasoning strategies. The reason is that training data contains bias cultures and overrepresented positions. The authors of the study claim that AI models tend to reproduce Western, educated, industrialized, rich and democratic points of view. In a context like the university, the result is that the students’ language is generally more polished, but the responses and reasoning are similar and ends up eroding the diversity of opinions. Hallucinations. These biases in the training data also partly explain the phenomena of hallucinations and flattery. When an LLM invents an answer or agrees with us even if we are wrong, it has to do with the fact that Positive and accommodating interactions prevail in your training data. That is to say, his training tells him that it is more important to give an answer rather than its truthfulness. Cognitive surrender. It is a concept taken from an experiment we talked about recently and refers to the phenomenon whereby we stop thinking and checking for ourselves when using AI, accepting its answers with little or no critical review and adopting its security as if it were our own. Delegating part of the cognitive process to AI is not a bad thing if it is done with a critical vision, the problem is when it is done indiscriminately and without any scrutiny of the answers. AI is making us dumb. A MIT study from 2025 pointed in this direction, but we already saw that It’s a very simplistic statement. of what is happening. Whether AI makes us lazier and impairs our critical thinking depends on how we use it. It would be comparable to using a calculator to do a very complex operation or using it to multiply five by six. Well used, AI can save us a lot of time and can be a very powerful tool to shape complex ideas, always without losing that critical thinking. Critical thinking is learned. This is the real problem of the indiscriminate use of AI in the educational environment. We are talking about people who have not yet developed this skill and who are delegating reasoning to an external tool may cause them to never learn it. In front of the prohibitionist stancevarious authors have pointed out the urgency of starting conversations with students from early stages to teach them to use AI critically and responsibly.

Cocoa is so expensive that some suspect that a shipment with 12 tons of Kitkat has been stolen

by

There was a time when big robberies had their own Hollywood epic: the Bank of England goldthe diamonds of the Great Antwerp Raidthe tickets from the Federal Reserve or the assault on the Mint and Stamp House of The Money Heist. Well, in 2026, European organized crime has decided that the most valuable thing you can take with you in a truck is 413,793 chocolate bars. No, it’s not a joke. In a statement to the AFP agencyNestlé has reported the theft of a shipment of more than 12 tons of KitKat chocolates, an incident that the multinational warns could cause supply problems right in the middle of the Easter campaign. A blow to Easter. According to the company, one of its logistics trucks carrying 413,793 a batch of chocolates KitKat has disappeared while transferring between the production center and the distribution center. According to pointed Reutersthe vehicle had left a factory in central Italy bound for Poland, but its trace was lost somewhere along the way. Since then, neither the truck nor the merchandise have been located and the investigation remains open. Nestlé warns that the disappearance of more than 400,000 units could be noticed in stores in the coming weeks, just at one of the times of greatest chocolate consumption of the year with the arrival of Easter and coinciding with the preparation of traditional sweets and cakes during these days. Pay attention to the black market. The company assures that it is collaborating with local authorities and its logistics network to try to locate the sweet shipment, although for now there are no details about the exact point of the journey at which the truck disappeared. The brand also warned that the stolen bars could enter unofficial sales channels in European markets. To combat this, KitKat noted that it is possible to trace the origin of products by scanning the unique lot codes listed on each bar. If the traceability system detects a coincidence, an action manual has been put in place to alert the company. Make a KitKat. Despite the seriousness of having lost almost half a million chocolate bars, the company has found humor in the face of such an unusual situation. A spokesperson for the brand made fun of KitKat’s famous slogan about taking a break or, as they call it, “making a kitkat.” “We’ve always encouraged people to take a break from KitKat, but it seems thieves have taken it too seriously and made off with more than 12 tonnes of our chocolate.” The truth is that, joking aside, the thieves have taken a button so voluminous that it will hardly go unnoticed if they try to “place” it on the market. “While we appreciate the exceptional taste of criminals, the truth is that merchandise theft is a growing problem for businesses of all sizes,” KitKat stated in its statement. brown gold. The theft comes at a time when the cocoa market is experiencing its biggest correction in decades. After reaching all-time highs above $12,000 per ton in 2024, the price of cocoa at origin has fallen more than 60%, reaching around $3,165 per ton at the end of March 2026. However, that moderation has barely reached the consumer and the cocoa prices They rose by 18% in the EU during 2025. Despite the price of the raw material having moderated, European supermarkets keep prices rising because manufacturers passed on the increases when the market was skyrocketing, but they took it more calmly when it fell.

In the cemeteries of Galicia, the Christs have begun to disappear from the tombstones. There is a suspect: “red gold”

by

The surprise was capital. And sad. Mostly sad. A few days ago, when she went to the pantheon where her relatives are buried, a neighbor from Celanova (Galicia) found that the figure of crucified Christ that decorated the tomb was missing. The curious thing is that not only was his own missing. Taking a look at the rest of the cemetery he found that the same thing was happening in five other tombs. In one, in fact, the Christ had been torn off and only preserved part of one arm, as if someone had burst it by using force with a lever. The case would not have made it out of the local press if it were not for the fact that it was not the only cemetery in Ourense in which the neighbors found that image. What has happened? That in the rural cemeteries of Galicia, more specifically in Ourense, dozens and dozens of Christs are disappearing. It takes a look at the regional press to see that it is more than a simple anecdote: March 16 Vigo Lighthouse informed of the disappearance of figures in two cemeteries in Celanova, days after The Voice of Galicia spoke already of 40 Christs torn from graves and Europa Press raised the total count to more than 50 crucifixes. One of the last media outlets to take stock has been Galicia Press, which on Wednesday the 18th reported the lack of more than 70 Christs in at least five different cemeteries. But… And why is that? Cemeteries are spaces of mourning and meditation, so it is not common (at least not in Spain of the 21st century) encounter cases of missing Christs like the one that shakes rural Ourense. There are a few theories to explain it. It could be acts of vandalism. Or some practice related to esoteric rituals. The Galician authorities are not inclined towards one or the other. For them the mystery is much simpler: the Civil Guard is investigating it like robberies, beatings carried out by criminals who are not interested in crucifixes and their artistic or spiritual value, but in something much more prosaic. What interests them is brass, stainless steel and above all copper with which these pieces were manufactured, a metal that recently reached a record price. ‘Red gold’ thieves? Exact. Recently the Civil Guard recognized to Europa Press who works “without ruling out” any possibility, but the starting hypothesis is quite simple: criminals sneak into cemeteries at night, especially in winter, steal figures that are often made of metal and then melt them down and sell them. Its objective focuses above all on copper, ‘red gold’whose price has been shot after the revaluation of recent years. The idea is that the material reaches the scrap market without raising suspicions and is reused in the industry. The Region even talks about the “band of the christs” and slips that they could be traveling professional criminals. Where have they stolen? The thefts seem to focus on a specific area, in the province of Ourense. Galicia Press point basically to rural cemeteries in the Celanova region and nearby towns, which includes cemeteries such as Santa María de Pontefechas, San Xoán de Viveiro, San Breixo de Celanova or Santo Eusebio de A Peroxa. There are those who expand the affected area in the province and speaks of assaults in cemeteries in the towns of Maside, Verea or Allariz. Thieves do not hesitate either take rings or resorting to force to extract the metal pieces, which has already led them to break crosses or some Christ, as in Pontefechas, where in one of the attacked tombs only part of an arm remained fixed to the stone head. Some parish priests of the archpriest have put on alert to their parishioners to be alert to theft. Why copper? For its value. It’s nothing new. Although its price has fallen slightly in recent days, the price of ‘red gold’ has escalated notably during the last year, reaching spikes historic at the beginning of 2026. The Region specifies that a kilo of this metal can be sold at between eight and ten euroswhich explains why it has been on the bands’ radar for some time now. The interest of criminals is not limited to cemeteries. Not long ago the Civil Guard dismantled a group that was dedicated to stealing copper cables in part of Asturias and the province of Lugo. The authorities estimate that a total of 24,000 kilos valued at 115,000 euros. In 2025 it has already fallen a similar band in Ourense and at the end of 2023 the arrest of other criminals dedicated to the same activity in the border area with Portugal. Does it only happen in Galicia? No. A quick Google search arrives to find news about copper theft in other communities in Spain. Since the bands are interested in the material, it is worth as much wind farm wiring and industrial coils as telephone infrastructure, rail transport either lighting. Proof of how juicy the business is is that at the end of 2025, the Interior reported the arrest of 18 people accused of more than thirty copper thefts worth 1.7 million euros. And what happens in cemeteries? Galicia is not the only place where cemeteries (and their metallic decoration) have whetted the appetite of criminal gangs. Last fall the National Police counted around 200 tombstones from the Torrero de Zaragoza cemetery that had suffered damage. Most for the same reason: tearing off bronze figures and other ornaments. More or less similar episodes have been experienced in the Community of Madrid, Castile and León or the Region of Murcia, where in 2023 the authorities arrested several people for allegedly carrying out more than 80 robberies in a municipal cemetery. The objective is the same: to loot copper, bronze and brass for resale. Images | M.

We have been blaming mobile phones for myopia for years. Now we have a much more subtle suspect: lack of light

by

It is quite a grandmother’s and mother’s phrase to hear that spending a long time in front of a screen or being very close to a book can cause us to develop a disease in the eyes like the myopia. However, science has long suspected that “close work” alone does not explain why myopia has become a global pandemic. The new. Now a revealing study has proposed a physiological mechanism that fits all the pieces of the puzzle together, placing the blame not only on what we look at, but on the amount of light that reaches the back of our eye while we do so. And the investigation is quite justified, since the data is scary. In Spain, 19% of children between 5 and 7 years old are already myopicand projections estimate that by 2050 half of the world’s population will need glasses. To stop this, we need to understand exactly the mechanism that produces myopia, and a team from New York has found the key. The famine of light. The work, recently published in the prestigious magazine Cell Reports by researchers, points to a fascinating concept in this case: the light deprivation hypothesis. Until now we knew that focusing on nearby objects is closely linked to the development of myopia. But what this study has measured with empirical precision is how the myopic eye reacts to the healthy eye during this process. What they have seen. The main finding is that myopes suffer from excessive accommodative pupillary constrictionthat is, when you look closely, the pupil becomes much smaller than normal. If we add to this that close-up work is usually done indoors where lighting rarely exceeds 500 lux, compared to 10,000 lux outdoors, the result is a lethal cocktail for the eye: the combination of dim light and a maximally contracted pupil causes the retina to “starve” due to lack of light. The short circuit. Here the question that logically must be asked is: Why does this lack of light cause the eye to grow abnormally, causing myopia? This is where the purest neuroscience comes in, since our retina processes the image through two main channels: the ON path that is activated with increases in light, and the OFF path, which reacts to shadows. In previous work from 2024, this same team had already shown that in myopic patients the ON pathways have serious deficits, since they are less sensitive and slower. Now the new hypothesis postulates a vicious circle in which, when reading or looking at a cell phone indoors, the pupil closes too much. And this is a problem, since chronic lack of light further weakens the retinal ON pathway, and this imbalance sends erroneous signals that ultimately promote elongation of the eyeball. The treatments. This proposal not only stands out for explaining the biological mechanism of myopia, but also unifies at once why the treatments that ophthalmologists They have been applying it empirically for years. One of the examples is spending time outdoors, but not because it cures, but because the sunlight is so intense that it more than compensates for having a small pupil, keeping the ON pathway stimulated and slowing the progression of myopia. Another example is the use of atropine drops in children to stop myopia thanks to the dilation of the pupil so that more light enters the retina. The same goes for multifocal lenses that are used to reduce accommodation effort, since the pupil does not need to constrict as excessively. It is not definitive. As is almost always the case in science, this work does not demonstrate a direct coincidence yet, but rather offers us an incredibly solid and plausible physiological mechanism supported by very robust data on the behavior of our pupil and neural pathways. But there is still a way to go with new long-term studies to confirm the hypothesis 100%. While we wait for those results, the practical conclusion seems clearer than ever: the problem is not just the tablet or the book. The problem is doing it in the dark, so if you are going to strain your eyes up close, make sure you turn on a good lamp and, above all, don’t forget to go out into the sun.

The EU is beginning to suspect manufacturers’ plants

by

The Chinese automotive industry has set out to conquer Europe. He is doing it bringing your cars directly from the factories in China, partnering with European groups and also in the most optimal way for the market: opening factories in our territory. It is the optimal way to avoid tariff packagesyes, but there is a problem: there are companies assembling their cars with removable kits. And that is not liked in Europe. Recently, Stéphane Séjourné, Vice President of Prosperity and Industrial Strategy of the European Commission, commented to the Italian media La Stampa who are attentive to the situation of some Chinese manufacturers. The focus, in fact, is on those who have settled in Spain. “Currently, there are manufacturers in Europe who assemble chinese cars with Chinese components and Chinese personnel. It’s happening in Spain and Hungary, and it’s not right”. It’s not the first time he says it. A little over a year ago, tariffs on electric cars coming from China came into force. They don’t have to be Chinese (the Tesla Gigafactory in Shanghai are included in those tariffs, for example), but the Asian country has designed a way to assemble cars in foreign countries with a double objective. These “removable” kits They are parts of cars that are manufactured and assembled in China to later dismantle them when they see that everything works, send them in pieces to the destination country and, on the new floor, the workers assemble them again. It’s not like building a car, but like rebuilding a giant LEGO. Ebro is an example. Assembly plant or manufacturing plant? a few months ago we already have that this “void” was something that they already contemplated from Europe, but there was a second reason. In July, China’s Ministry of Commerce held a meeting with a dozen domestic manufacturers who were given a maxim: the secrets of the electric vehicle industry must be protected as much as possible. That means key vehicle systems would be made in China, where it’s easier to maintain control. Valdis Dombrovskis is the executive vice-president of the European Commission and has already expressed his doubts about the value that will be created in the European Union with this way of proceeding. “What part of know-how Will it be stored here? Is it a simple assembly plant or an automobile manufacturing plant? “There is a substantial difference,” he said. Returning to Séjourné, he assures that he does not believe that tariffs are the answer because “they destroy the value chain and create trade tensions.” He does not give an answer about what should be done, but comments that we Europeans “need to be less naive and put ourselves back to the standards of all the major economies in the world.” The Chery factory in Barcelona, ​​for example, is one of the Chinese factories that have operated in SKD, or Semi Knock Down, mode. As our colleagues point out Motorpassionfrom China the car is sent half disassembled, without elements such as the steering wheel or wheels, and then they are assembled again on European soil. The idea is that pass to the CKD or Completely Knock Down mode. This implies that They will arrive completely disassembled and will be assembled in Barcelona completely, including welding, painting and there will be an integration of local suppliers that will improve that value chain and create wealth in the surroundings of the factory. What they criticize from Europe is that the operators are, sometimes, workers who come directly from China. An example, also on Spanish soil, is the CATL gigafactory in Zaragoza. They will create batteries to supply the Stellantis plant in Figuerelas and it is expected to generate 3,000 direct jobs. But, when it came time to build the factory, There will be close to 2,000 workers from China those who do the work. One eye on removable kits, another on hybrids Because the objective of the European Union is for the brands that reach our territory to generate wealth in the countries in which they are established. There are relevant examples of this. SEAT gives direct work more than 15,000 people between the Martorell plants, but indirectly generates thousands of other jobs. Similar happens with Toyota in Valenciennes. In the French plant they employ about 4,000 people, but they generate thousands of indirect jobs in the surrounding area because logistics, auxiliary industry, local suppliers, etc. come into play. In fact, they point that Toyota in Europe directly and indirectly employs 94,000 people. But although Europe’s focus on protecting community interests is focused on the electric car, we have already said on occasion that hybrids and plug-ins are the real threats. In May 2025, Chinese brands reached 5.4% market share, with more than 60,000 cars sold compared to 3% in the previous period. In that same time, the European market only grew by 1.3%. These figures were achieved thanks, above all, to the hybrids that brands like MG or BYD have brought to our territory. And this success does not come from nowhere: Chinese hybrids offer a good price-power-design ratio, with attractive and very competitive prices against which European and Japanese manufacturers barely compete. The solution? Complex. Séjourné also commented that Europe is “the only continent that lacks strategic thinking in terms of industrial policy”, and the solution may be to apply something similar to what, precisely, China did in the past. When foreign brands wanted to establish themselves in the Asian giant, they had to partner with local companies so that there was a transmission of knowledge and wealth. And, perhaps, that is the way for foreign brands to establish themselves in Europe. In fact, this is exactly what Josep Maria Recasens, president of Renault Spain, is asking for, who has also stated that Europe “cannot allow them to make four plates with wheels.” Images | Ebro, BYD In Xataka | Chinese cars are “indistinguishable in quality” from European ones.

Three Chinese astronauts have delayed their return to Earth due to an impact on the ship. The suspect: space junk

by

The crew of the Shenzhou-20 spacecraft, which was scheduled to land this Wednesday in Inner Mongolia, has been forced to postpone its return to Earth. The cause is not bad weather, as is usual in manned flights, but the most feared enemy of modern space exploration: a probable impact of space debris. Evaluating risks. China Manned Space Agency (CMSA) broke the news this morning: The return of the three astronauts aboard Shenzhou-20 has been delayed indefinitely following suspicions that the ship may have been hit by a small piece of space debris. The ship is still docked at the Chinese Tiangong space station, where the crew are safe. The crew and engineers on the ground are analyzing the impact on the ship to try to determine the extent of the damage and assess the risks of the return journey. The problem is reentry. Three people traveled to the Chinese space station in April aboard the Shenzhou-20 spacecraft: Chen Dong, Chen Zhongrui and Wang Jie. The problem is not his immediate survival, but the viability of his ship surviving the atmospheric re-entry maneuver after the impact. In low orbit, objects travel at hypersonic speeds of up to 28,000 km/h. At that speed, even a tiny fragment of metal or paint can release devastating kinetic energy, especially if it hits critical components like the ship’s heat shield or its parachutes. What do we know for now? The CMSA has not specified where it believes the impact occurred or what data alerted them to the event. Now, engineers on the ground and the crew in orbit will perform telemetry checks, check for possible leaks, and analyze the guidance and propulsion systems. They will most likely use the Tiangong station’s 10-meter robotic arm to conduct a detailed visual inspection of Shenzhou-20. If necessary, an extravehicular activity (EVA) or spacewalk is not ruled out to assess the damage closely. A problem that China was trying to avoid. The irony of this incident is that the Shenzhou-20 crew itself is fully aware of the danger. In fact, part of its six-month mission in orbit focused on mitigating this risk. Two of the astronauts six hours passed in September by installing additional protective shields against orbital fragments outside the Tiangong station. Although they reinforced the station, the impact seems to have occurred in the way that would bring them back.

Colon cancers are increasing alarmingly among young people. We have a suspect: sedentary lifestyle

by

colon cancer It is one of the tumors that has increased its incidence the most in young adults over the last few decades, a trend that is very worrying because has made science need to answer why. One of the most important points are the factors that are influencing more and more young people to begin to have tumors in their digestive system. A big problem. Colon cancer is undoubtedly one of the most aggressive diseases that we endure, and also really frequent among the population, with a really aggressive treatment with surgeries that can mean the removal of part of the colonbut also with a high mortality behind them. Its early diagnosis is so relevant that in Spain there are many autonomous communities that have screening programs either screening (although sometimes they fail like in Andalusia) to begin treatment in the case of positive cases, as soon as possible to increase their chances of survival. The problem is that this horrible disease is becoming increasingly prevalent, and science is seeing many factors that are important to take into account to try to reduce the chances of suffering from it. Quantified. This trend has been reflected in a published study in Annals of Internal Medicine which has detected that in many countries the number of cases among those under fifty years of age has grown up to four times faster than in older people. In the end, it is a phenomenon that has revived the debate about the causes and future strategies that must be taken in prevention and early detection. This is extremely important, since a timely diagnosis can mean a big difference in life expectancy who has a patient. The reasons. As stated in the Institute for Cancer Research, London After studying forty-two different countries, two main explanations have been identified. The first is the screening that is done among adults. Although it is very positive to do screening among the population for this disease, the reality is that there is an age limit from which these tests are carried out. This does not occur among the younger population who do not receive this type of screening tests on a regular basis, which may explain the accelerated growth in this group, since cancers are not diagnosed in the early stages. The second reason given is obesity. In this case It is considered a very important risk factor which drives the increased probability of suffering from colon cancer in young people and adults of all ages. Although it remains to be seen if there is an increase in its relationship with the younger population. Environmental factors. In addition to these two causes, the research led by the CNIO Digital Genomics Group in Spain provides new evidence about why this may occur. In his published study In Nature, the influence of the intestinal microbiota, particularly certain strains of E.coli intestinal, producers of the toxin colibactin. As we already sawthis can cause great genetic damage to colon cells that can accelerate tumor development. But other factors associated with the patients’ lifestyle are also being considered. In this case, the increase in type 2 diabetesespecially when there is a sedentary habit and unhealthy diets that seem to increase the risk of having this type of cancer. A Swedish study with a national cohort showed that people with diabetes reach an equivalent risk of colorectal cancer at younger ages than those who do not suffer from it, requiring prevention and monitoring before the standard screening age in the general population. But ultra-processed diets also come in here, excessive consumption of alcohol or even sugary drinkswhich can be an important risk factor. Prevention. Experts agree that there is no single and definitive cause, but rather a combination of genetic, biological, environmental and social factors. While research continues, it is proposed to implement comprehensive prevention policies that adapt to these realities. To do this, they aim to apply personalized screening that includes risk factors such as obesity, diabetes or family history. But we must also focus on research into how our microbiota can have an important implication in this. This forces us to have to take great care of what we eat and maintain adequate intestinal health. But the most relevant thing is to adapt the recommendations for starting screening for high-risk groups, such as young people who have diabetes or a family history so that they begin surveillance at age 40.
