devouring

The United Kingdom is experiencing a new invasion. The problem is that they are octopuses and they are devouring everything they can find.

by

When explorer John Cabot returned from Newfoundland in 1497, assured who had found seas so full of fish that they could captured with simple baskets weighted with stones. That abundance seemed inexhaustible, but more than five centuries later, British waters are once again starring in a story of marine overpopulation, although with very different protagonists. An unexpected invasion. For decades, encountering a common octopus off the coast of south-west England was a rare event for even the most experienced divers. However, in just a few years the situation has changed. radically. What started as a striking increase of sightings has become the largest population explosion of octopuses recorded in at least 75 years. The animals have colonized extensive areas of the British coast, expanding from Devon and Cornwall to Wales, Dorset, Sussex and even Scotland, becoming one of the most surprising marine phenomena that the United Kingdom has experienced in recent times. Perfect weather and conditions. Scientists believe that this expansion is the result of several factors that have coincided at the same time. The juvenile octopuses probably arrived from breeding areas around the English Channel and northern France, but the real difference has been the progressive warming of British waters. Mild winters and warmer breeding seasons have allowed them to survive in much greater numbers and, more importantly, to begin to reproduce successfully in UK waters. The appearance of juvenile specimens confirms that they are no longer simply occasional visitors, but rather a population capable of completing their entire life cycle on these coasts. The big losers. The massive arrival of octopuses is having devastating consequences for part of the traditional fishing. These animals are extraordinarily efficient predators and consume huge quantities of seafood every day. Fishermen began finding empty traps, missing lobsters and ruined catches. In some areas, those who depended on crustacean fishing have seen plummets in between 70% and 100% of their catches. In fact, some businesses have closed and some owners have even sold their boats. The researchers they calculate that octopuses are consuming tons of seafood daily, altering a food chain that had been functioning relatively stable for decades. The same plague that ruins some enriches others. The paradox is that the crisis has also generated an economic opportunity unexpected. Where lobsters and crabs were once caught, octopuses now abound. Many fishermen have quickly adapted their gear and have begun to catch them to supply a growing demand in European markets. The result has been spectacular. Brixham recently sold more than 100 tons of octopus in a single day, generating more than half a million pounds in sales. Some professionals claim that they are obtaining income several times higher than what they achieved with traditional fishing, causing a real fever to catch octopuses along the coast. A reorganized ecosystem. The phenomenon goes far beyond the fishing economy. Octopuses are profoundly altering the relationships between species. While they consume large quantities of crustaceans and mollusks, they have also become food for seals, conger eels and Risso’s dolphins. The researchers describe the situation as a complete reconfiguration of the marine ecosystem, a process in which each change triggers new ones. The feeling among scientists is that British waters are going through a period of ecological transition in which the rules that seemed established for generations are no longer valid. The big difference from previous invasions. Although similar population explosions were already recorded at the beginning of the 20th century, in the 1930s and 1950s, researchers believe that this time the situation can be different. In previous episodes, the octopuses ended up disappearing when conditions changed again. Now, however, winters cold enough to drastically reduce their populations have been going on for more than a decade without production. Evidence of local reproduction and the presence of young specimens suggest that octopuses may have ceased to be occasional visitors and become permanent inhabitants of British coasts. Preparing for a new reality. The magnitude of the phenomenon is already forcing the authorities to react. In Cornwall, for example, they study emergency restrictions to limit the number of boats dedicated to capturing octopuses for fear of excessive exploitation of a population that, paradoxically, seemed inexhaustible just a few months ago. Meanwhile, scientists, fishermen and resource managers are trying to understand what this transformation really means. The big lesson is that ocean warming not only changes temperatures or currents, but can change them completely. who dominates an ecosystem. And on British shores, the new protagonists seem to be animals that until very recently were a rarity and that are now devouring everything in their path. Careful, Galicia.

China manufactured more solar panels in one year than the planet can absorb. Now the market is devouring itself

by

In early 2026, the closure of the Strait of Hormuz shook energy markets. Consumers, frightened by the volatility of fossil fuels, looked in all directions for alternatives. What they found was a disconcerting paradox: the planet had—has—a historic surplus of clean, cheap energy. There was no shortage of solar panels. There were plenty of them. And no one really knew what to do with them. Economist Adam Tooze summed it up bluntly in his column Financial Times: “Clean energy, on a scale that would have seemed utopian at the time of the Paris Agreement in 2015, is now within our reach. The price of solar panels has plummeted. And yet factories are paralyzed.” It’s not rhetoric. It’s a diagnosis. After a huge increase in investment since 2020, Chinese companies reached a production capacity of 1,000 gigawatts of solar panels per year. To get an idea: in 2023 global demand was only 451 GW, according to Energy News. Chinese production of solar cells that year—588 GW—already doubled international demand. And they continued building. The result was what economists call “involution”: a spiral of destructive competition where companies destroy each other with none winning. More than 40 Chinese manufacturers have gone bankrupt, been acquired or delisted. A third of the staff of the surviving big five were laid off. JinkoSolar, the world’s largest supplier, registered in 2025 a drop in revenue of 29%, a drop in gross profit of 86% and net losses of 4.45 billion yuan. In this way, in June of last year, more than 30 manufacturers They agreed to an OPEC-style pact to stabilize prices and curb supply. Six months later, the result was a disaster: far from stabilizing, production reached historic highs, installations tripled and losses continued to accumulate. “Since when are solar panels just another commodity? They are a technological miracle. They make us cultivators of the sun,” details Adam Tooze in his column. And in all that time, the price of a solar module fell to $0.10 per watt, according to EnkiAI —well below the $0.16/W production cost of the most advanced TOPCon modules. It is, strictly speaking, the largest climate technology sell-off in history. This is not a steel crisis. It’s something else When economists talk about Chinese overproduction, the debate usually revolves around steel, cement or electric cars. But Tooze makes a distinction worth hearing: Solar panels are no ordinary commodity. They are the result of half a century of research—from NASA spinoff programs in the 1970s to the big energy push of the Carter era—and, along with batteries, they are the master key to a sustainable future. Wasting that surplus is not just an economic problem. It is a civilizational irrationality. According to the OECD, China invested less than $18 billion in sector support over 15 years to build an industry capable of providing more clean energy than the world can easily absorb. That figure is less than the cost of building a medium-sized international airport in Europe, or what the US spent on a single Gerald Ford-class aircraft carrier. The concentration of power in the supply chain is also unprecedented in the history of energy. China controls more than 80% of the entire global solar production chaindirect result of the plan Made in China 2025 with which Beijing decided to stop being the world’s cheap factory and become its technological supplier. By the end of 2025, its operational module capacity exceeded 900 GW, several times the total global demand. The five largest Chinese manufacturers concentrate more than 50% of the market. LONGi Green Energy alone shipped more than 45 GW in 2025 – more than the entire US domestic manufacturing capacity (73 GW). Never in the history of energy has a single nation so completely dominated a key technology for the decarbonization of the planet. Not even oil at its peak. And the climate paradox is painful: since the Paris Agreement of 2015, a scale of deployment like the current one would have seemed like science fiction. The goal was to stop global warming. The instruments to do so are manufactured and stacked in warehouses. What fails, Tooze points out, is coordination: what Keynes would call a global “chaos,” a catastrophe of collective planning. The global bet Chaos has its own correction mechanisms, even if they are painful. In China, the crisis has already forced the Government to act a few months ago, Beijing called for ‘concerted efforts’ to end price war. The proposed measures include capacity control, minimum guideline prices, mergers and acquisitions, and intellectual property protection “to promote the high-quality development of the photovoltaic industry.” In practice: the Chinese State orchestrating an orderly rescue of the sector that it itself encouraged to grow without limits. The consolidation had already started before. In August of last year, several players in the sector launched a plan for large manufacturers to jointly invest $7 billion in buying and closing the least efficient facilities, according to OilPrice.com. In practice, a cartel to stop the bleeding. Prices already reflect the shift. According to ABC SolutionsChinese modules have risen between 10% and 20% in 2026 due to the adjustment of overproduction and new logistics tariffs. Wood Mackenzie forecasts a further rise of 9%. The window for the big bargain is closing, although prices remain historically low. The critical variable for 2027 is how the surplus is resolved: through orderly consolidation or through new business disruptions. Meanwhile, Chinese foreign business continues to boom. As Tooze points out in the FTexports of Chinese solar technology to virtually every country except the United States are skyrocketing. And manufacturers have evolved: they now integrate batteries into systems to offer greater stability to the grid, pushing the product towards the complete solution instead of the isolated module. Storage batteries, which They have also reached historical lows in cost Pushed by the same dynamic of overproduction, they thus complete the package: panel plus storage, at a knockdown price. Domestic demand will also recover. China exceeded 1,230 GW of installed solar capacity … Read more

A gigantic tunnel boring machine 16 meters in diameter is devouring the sea floor under Genoa. It is your solution against traffic

by

Under the port of Genoa, the largest in Italy, there is a machine that aims to devour the sea floor meter by meter. And it does so from the bowels of the earth, 45 meters deep and without interrupting the traffic that passes above it every day. The key is a 16 meter diameter tunnel boring machine that is drilling into the seabed like butter. This is how Italy is solving one of its most entrenched mobility problems, and in the process building the first underwater tunnel of the history of the country. A problem that has been unsolved for decades. Genoa is a city trapped between the Mediterranean Sea and the foothills of the Apennines. It has no room to grow. Its historic center is a labyrinth of narrow streets, and east-west traffic has always been a headache. The solution adopted in the 1960s was to build a gigantic elevated highway, the Sopraelevata Aldo Moro, which crosses the city like a concrete scar. for her About 80,000 vehicles pass through each daybut at a high price: it blocks the view of the sea, generates constant noise and, for many citizens, is a barrier that separates the city from its own port. Its demolition has been stalled for years because no one knows what to do with that traffic in the meantime. Tragedy. The tunnel project was born from an agreement between Autostrade per l’Italia, the Italian Ministry of Transport and local administrations as compensation to the city after the collapse of the Morandi bridge in 2018. That collapse, which claimed 43 lives, left Genoa without one of its main accesses and put the highway concessionaire company under the spotlight. As part of the repair agreement, signed in October 2021, Autostrade per l’Italia, the Liguria Region, the Western Ligure Sea Port System Authority and the Municipality of Genoa agreed to build this underwater tunnel. It is, in practice, the great work of compensation for a city that suffered a tragedy. What is being built. The total route is 4.2 kilometers, of which 3.4 run under the sea floor. It will consist of two separate galleries, one in each direction, each 16 meters in diameter, and will reach a maximum depth of 45 meters below sea level. When completed, it is expected to be Italy’s first underwater tunnel, the largest in Europe (with pardon is being built between Germany and Denmark) and the fourth largest in the world by diameter. Next to nothing. The key: a Hydroshield TBM. Excavating under an active port without interrupting its activity is a monumental challenge. The solution is a TBM tunnel boring machine (Tunnel Boring Machine) Hydroshield type. Each of the two main galleries will be constructed by mechanized excavation with a Hydroshield type back-pressure armored TBM milling cutter, with an excavation diameter of approximately 16 meters. Why this type and not another? In a Hydroshield TBM, the balance in the excavation chamber is maintained through the pressure of water or bentonite slurrywhich stabilizes the excavation face. The extracted material is mixed with these sludge and transported to the surface through pipes. It is the ideal technology for unstable terrain with the presence of water: it allows you to continue drilling without the sea floor crumbling and without the sea entering the gallery. The port above is still working. The gallery measures 15.4 meters in diameter on the outside, but the useful space for circulation is somewhat less, 14.3 meters, because the walls are considerably thick. These walls are built by assembling prefabricated pieces of concrete, as if they were the staves of a giant barrel, joined together with screws and sealed with rubber gaskets so that water does not enter. As if that were not enough, an additional layer of concrete is added inside that further reinforces the impermeability, especially in the sections that are just below the port. The result is a practically airtight tube capable of withstanding the pressure of the sea on its walls. lto logistics of the work. You can’t just place a tunnel boring machine on the seabed and run it. First you have to prepare the ground. The tunnel boring machine was thrown from an attack pit in the San Benigno areaon the west side of the city. To free up that space, Autostrade first had to move a port railway line that ran through there. The railway route, about 700 meters long, has been moved about 70 meters to the south with respect to its previous position, running parallel to the port sopraelevata until passing under it in its final section. Deadlines. Preparation works started in 2023, and work began in March 2024. However, the full tender for the construction of the two main galleries was not approved until January 2026. The specifications set a period of 75 months to complete the entire work. According to the latest Autostrade documents, the TBM will complete excavation work in October 2030, with full completion of the work planned for 2031. Budget. The project started from a budget of 700 million euros, although the mayor of Genoa, Silvia Salis, confirmed that Autostrade now places the cost at more than 1,129 million euros. An escalation of costs that, according to the original agreement between the parties, is covered by a mechanism linked to national highway tolls. Transformation. When the tunnel is completed, it will allow the creation of new green areas (10 hectares, distributed in three public parks) and pedestrian routes that reconnect the city center with the sea. In the San Benigno area, on the new railway gallery already in use, the Lantern Park will be built, which will connect that sector with the city’s historic lighthouse through a bicycle and pedestrian path.

Big tech had ambitious climate goals. Then the AI ​​came and started devouring them

by

There was a time when technology seemed to have found a comfortable way to tell its climate future. The big companies talked about “clean energy”net zero emissions, increasingly efficient operations and commitments dated to 2030 or 2040. It was an attractive story because it coexisted with our daily use of the internet, services and applications. Generative AI, however, has complicated that picture: not only does it bring more smart services, it also requires more infrastructure, more electricity, and climate pressure that is much more difficult to square with the promises those same companies made just a few years ago. The most recent movement comes from Microsoft. Bloomberg has published that the company would be considering delaying or even abandoning one of its most ambitious energy goals, at a time when the race for AI requires increasingly more computing capacity. Tell OpenAI or Anthropic. This case does not appear in a vacuum: other large technology companies are also facing increasingly visible challenges to fit their climate commitments with the expansion of their data centers. The question is no longer just what they promised, but what happens when those promises collide with the actual scale of AI. The companies did not reach these commitments in a single way nor did they promise exactly the same thing. Some focused on the purchase of renewable energy, others on zero-carbon electricity, others on net-zero emissions, and others on eliminating more carbon than they generate. There were also different reasons for doing so: regulatory pressure, investor expectations, reputation and a fairly widespread conviction that digital infrastructure could grow. without triggering its climate impact. What interests us here is not to review all those promises, but to follow some of the most ambitious ones and see how they are holding up to the AI ​​race that is unfolding before our eyes. Climate promises in the face of expanding data centers As we say, the fundamental change is that many of these commitments were formulated before generative AI became an absolute priority for the industry. Until then, the growth of data centers was already a challenge, but it could be projected with a more gradual logic. The new race has altered that pace: training models, deploying them in massive products, and answering large-scale queries requires computing power that grows very quickly. What once seemed like a difficult but manageable roadmap now faces a different dynamic. Microsoft was one of the companies that formulated one of the most demanding goals. In July 2021 he announced his 100/100/0 commitment, a way of saying that by 2030 he wanted match 100% of your electricity consumption100% of the time, with zero-carbon energy purchases. The nuance matters: it was not just about offsetting annual consumption with renewables, but about getting closer to an hour-by-hour correspondence. Furthermore, the company proposed doing so in the same electrical networks from which it took that energy. Now that commitment is under obvious pressure. The aforementioned economic media indicated that the Redmond company is studying delaying or even abandoning it, according to anonymous sources with knowledge of the matter, while seeking to clear obstacles to powering its data centers. Microsoft has not confirmed that change and its director of sustainability, Melanie Nakagawa, maintained that the company remains committed to its environmental goals. He also left an insight that sets the tone for the official response: any adjustment would be part of a review of approach, not a change in long-term ambition. Google also set a powerful goal. In 2021, the Mountain View company set the goal to achieve net zero emissions across its operations and value chain by 2030, including its consumer hardware products. To achieve this, he proposed reduce 50% its absolute emissions compared to 2019, not only those generated directly by the company, but also those linked to its activity and its supply chain. What it could not reduce, according to its roadmap, it would compensate by removing carbon from the atmosphere through natural and technological solutions. The current situation shows how difficult it is to put this roadmap into practice. In its 2025 environmental reportGoogle points out that in 2024 its emissions were 11.5 million tons of CO2 equivalent. That is 11% more than the previous year and 51% above its 2019 base. The nuance is important: they did not increase 51% in one year, but rather compared to the starting point chosen by the company. The report itself also recognizes that integrating more AI into its products can complicate the reduction of emissions due to the greater demand for computing and technical infrastructure. Amazon also presented a high-ambition climate pledge. In September 2019the e-commerce giant announced together with Global Optimism The Climate Pledge, a commitment to achieve net zero carbon emissions by 2040ten years before the horizon set by the Paris Agreement. The company founded by Jeff Bezos became the first signatory of that initiative, which called for measuring and reporting emissions on a regular basis, applying decarbonization strategies and neutralizing remaining emissions with additional, quantifiable, real, permanent and socially beneficial compensations. Amazon’s situation shows that these promises already had gray areas even before AI was at the center of the debate. In September 2023, Data Center Dynamics published that the Science Based Targets initiative had removed the Amazon commitment from its panel and placed it in the “expired commitment” category. The reason, according to the media, was that both parties were unable to agree on a sufficiently significant emissions target. Amazon responded that the requirements had changed and that it would continue to look for credible third-party validators. In this sense, general photography goes in the same direction. The US Department of Energy estimates that the Data centers consumed around 4.4% of the country’s electricity in 2023 and could be between 6.7% and 12% in 2028. The International Energy Agency also projects a relevant leap on a global scale: from about 415 TWh in 2024 to about 945 TWh in 2030. Not all of this growth can be attributed solely to AI, … Read more

AI is devouring physical storage

by

Of course, this does not seem like the best time to assemble a PC in parts. The industry has been talking for months about memory shortage and a market with rising pricesand the doubts about the launch of new NVIDIA graphics cards For this 2026 they don’t help either. In the midst of this context, another signal now arrives from a less visible layer of hardware: Western Digital has communicated that its hard drive capacity for 2026 is practically compromised. So we ask ourselves what that message really means and how far its impact can go. The data. During the presentation of results for the second fiscal quarter of 2026, its CEO, Irving Tan, noted that Western Digital “has practically sold the entire catalog by 2026”, backed by confirmed orders from its seven largest clients and by multi-year agreements that extend until 2027 and 2028. The combination of volume in exabytes and price within these contracts points, in the executive’s words, to a transformation in the role that storage plays as activity linked to artificial intelligence gains weight within the technology business. behind the scenes. In this context, “sold out” does not refer to empty shelves or a sudden lack of hard drives for the consumer. As we can interpret, it refers to the fact that future production capacity is already reserved through agreements with large clients, defined by massive amounts of data and economic commitments for several years to come. In other words, the focus is not on the retail market, but on much larger scale contracts. And that detail completely changes the way the ad is interpreted. What kind of hard drives are we really talking about?. The language used by the company points directly to the storage used by data centers and large cloud services. It is the realm of high-capacity professional drives and business families designed to operate continuously, far removed from the disk that ends up inside one of our computers. The distribution of money. During the same fiscal quarter, Western Digital indicated that 89% of its revenue came from the “cloud” business, compared to 6% from the “client” segment and just 5% from consumption. The company ensures that it also delivered 215 exabytes of capacity, with a strong weight of next-generation disks for AI that reach up to 32 TB. The numbers not only measure the scale of business demand, but also explain why the industrial priority is placed there. Why AI is eating hard drives. It is no longer a secret that models need huge volumes of data to train and, later, infrastructures capable of preserving and serving information continuously. That combination skyrockets storage where capacity outweighs speed. Hence, despite the advancement of faster technologies, large data centers continue to rely on magnetic storage to sustain the scale of AI. What about the home user. Western Digital maintains consumer-oriented products and has not announced cuts or shortages on that front, so any direct effect would be, for now, speculative. What we can see is a clear priority towards large-scale enterprise contracts, and an eventual redistribution of capacity could generate indirect pressures on the rest of the line. More thermometer than immediate warning. If one thing is clear, it is that the data shows the extent to which AI is redefining priorities in the physical base of the technology industry, even in components that seemed stable for years. It remains to be seen whether that pressure will continue long enough to further disrupt the consumer market.

We have turned sadness into a psychiatric disorder. And that is a problem that is devouring us socially.

by

When Roland Kuhn discovered the first antidepressant in history, imipramine, the directors of Geygi hesitated to put it on the market because depression was so rare who did not believe it could become a profitable medicine (Healy, 1999). It was the 50s of the 20th century, but it seems like an alternative reality. Today, depression is omnipresent. Only in Spain, the consumption of antidepressants has grown 200% in the last fifteen years and it is nothing more than the reflection of an unstoppable international trend. How is it possible that, in just over half a century, depression has become “so common”? Are we confusing normal sadness with a psychiatric disorder, as many experts say? Are we pathologizing everyday life? I am not going to enter into terminological debates, no matter how interesting and necessary they may be. When talking about “invention of mental illness” or “pathologization of everyday life” we run the risk of minimizing problems as serious as depression and that is something that is not in question. On the contrary, the idea is understand her better to treat her better. As the neurologist Luis Querol said“if we stick to the conventional concept of diseaseanyone who has seen a melancholic depressive SUFFER (…) will recognize that it is an illness.” It is totally true: that is enough for now. Depression is a particularly insidious and destructive disorder. According to the WHOnot only is it the main global cause of disability, but it affects 350 million people and is behind 800,000 deaths each year. Synopsis of an epidemic However, this does not explain why depression has become an epidemic. Above all, because it is not a disease that we “just” discovered. Melancholy is one of those psychiatric disorders so old that they were already diagnosed by Hippocrates and classical Greek medicine. Since the 19th century, the European diagnostic tradition separated most mood disorders from deep melancholy and included this among the diseases that end up consuming the person (such as senile dementia). At the beginning of the 20th century, psychiatric practice already clearly differentiated between endogenous or melancholic depression (which affected between 1 and 2% of patients) and reactive or neurotic depression (much more common) which was a product of stress, loss or pain. (Unsplash) In 1980, in the middle of a deep reputation crisis for psychiatric practiceDSM-III changed the way we think about depression. It moves from an etiopathogenic model (which asked about the cause of the disease) to a semiological one (which, in its claim to atheoretical nature, was based on symptomatology). A careless eye might think that the change was terminological and that “endogenous” was only replaced by “major” and “reactive” by “dysthymia”; but, in reality, the DSM-III expanded the playing field. Melancholia became one of the five subtypes of major depression and, with this, the underlying depressive disorder went from having a prevalence of 2% to a prevalence of up to 17% (Kessler et al., 2005). In recent years, a good number of historians (and activists) have insisted that this change and the commercial pressure of pharmaceutical companies (Horwitz and Wakefield, 2007) have taken us to overdiagnosis current disease (Mojtabai, 2013; Parker, 2007). At its strongest, it is a difficult argument to reject. Especially because it is not that the existence of depression is denied, but rather that it is argued that the failure of epidemiologists, psychiatrists and social scientists to differentiate ‘normal sadness’ and ‘depressive disorder’ is leading to health policies that condemn many people to taking unnecessary medications and carrying the weight of stigma on their backs. Whys, doubts and conspiracy Basically, although it is not usually said clearly, we are talking about ‘iatrogenesis’; That is, suffering or damage to health caused by health professionals themselves. The current opioid crisis in the US It shows that, far from being pure conspiracy, pharmaceutical companies and their balance sheets can create a health problem of colossal dimensions. However, we must not be unfair, nor fall into banal Manichaeism. Although it may seem counterintuitive and paradoxical, many problems only appear when we have the solution them. Without antidepressants or effective behavioral therapies, depression was deep sadness, black sorrow that wells up, black shadow that amazes me. Something that was between us and there was nothing we could do to avoid it. (Jacob Sedlacek/Unsplash) Horwitz and Wakefield say that “tolerance for normal but painful emotions has fallen” in the West. And it may be true. But they forget two fundamental things: that, for the first time in the history of humanity, we can do without them and that it is not a personal problem, the modern world has tended to prioritize productive optimism and has forgotten how to live with sadness. At this point we realize that, if we want to learn to better separate “illness” from “normality”, it is not just a matter of challenging depressive overdiagnosis, but of claim sadness. The problem is that, why would we want claim sadness? And the answer, honestly, may surprise us. Sadness, said Lazarus (1991), promotes personal reflection after the loss. Focus our gaze on ourselves, promote resignation, invite acceptance (Izard, 1993). It allows us to waste time to update “our cognitive structures” (Welling, 2003); that is, to accommodate the loss. That reflective function of sadness It allows us to stop. And weigh actions, review our goals, modify our plans (Bonanno & Keltner, 1997; Oatley and Johnson-Laird, 1996). It makes us more attentive to detail, more precise. It makes us flee from heuristics and stereotypes (Bodenhausen, Gabriel and Lineberger, 2000; Schwarz, 1998) and distrust first impressions (Schwarz, 2010). Physiological arousal decreases and makes us more prone to slow thinking (Overskeid, 2000). Furthermore, it shapes us as a group. Causes sympathy, empathy and altruism in others (Keltner and Kring, 1998). The complex balance between “normality” and “disease” In 1843, Charles Darwin wrote a letter of condolence to a distant cousin in which he said that “strong affections have always seemed to me the noblest part of man’s character and the … Read more

Three chains are devouring the supermarket business in Spain year after year: Mercadona, Lidl and Aldi

by

From ugly duckling to goose that lays the golden eggs. The white label revolution seems to find no ceiling in the retail Spanish. Until not so long ago, the brands associated with supermarkets carried a stigma in Spain compared to items from manufacturer brands clearly recognized by customers. It was not even strange for words like “Estandado” to be used in a pejorative way. Buying white was synonymous with buying ‘poor quality’‘option B’. Not anymore. Spanish families are increasingly betting on white label. And that is making gold for some of the country’s big chains. What has happened? That the white label is experiencing his particular revolution in it retail Spanish. And that is still striking if you take into account that until not so long ago, firms like Hacendado or Auchan carried a certain stigma compared to their competitors, the brands associated with manufacturers. It’s nothing new. For a long time we have been confirming how the white label is driving some chains of “short assortment”supermarkets that are committed to offering customers a limited selection of items. That is, instead of including a dozen different brands of cookies (or other items) on their shelves, they offer only two or one, among which they include their own brand. Chain Market share in value Difference (PP) compared to the 2024 quota Mercadona 37.0% 0.9 Carrefour Group 12.3% -0.2 Lidl 8.0% 0.5 Day Group 4.7% 0.1 Consum Group 4.5% 0.0 Eroski Group 4.4% -0.1 Alcampo Group 3.6% -0.3 aldi 2.5% 0.4 Bon Preu Group 2.4% 0.0 You save 23% 0.1 Gadis Group 1.7% 0.0 Magnifying glass 1.1% -0.1 El Corte Inglés Group 1.0% -0.2 dinosol 0.9% 0.0 Froiz 0.8% 0.0 Alimerka 0.8% 0.0 Rest of Modern distribution 12.0% -1.1 Why is it news? Because the latest data from 2025 reveal that this strategy is driving some brands to catapult them to unprecedented market shares. This is suggested by at least one recent report from Algori on consumption prepared with data from the first ten months of the year. The study shows that at the end of October the three chains that were gaining the greatest market share (in terms of value) in Spain were Mercadona (0.9 percentage points), Lidl (0.5 pp) and Aldi (0.4). Between the three, they also held a market share of 47.5%, a share clearly led by Juan Roig’s company, which alone holds 37%. DIA and Ahorramás are also growing, while others like Carrefour, Alcampo or Eroski are stagnating or decreasing. Chain % of white label sales 2023 % of white label sales 2024 % of white label sales 2025 Lidl 79.7% 81.9% 80.7% Mercadona 72.9% 74.5% 77.8% aldi 68.8% 69.1% 74.5% Day 54.2% 56.3% 65.1% consumption 33% 35.9% 37.4% Carrefour 29.3% 31.4% 33.3% Eroski 25.6% 28.4% 31.2% Alcampo 21.5% 24.3% 23.8% Why is it important? Because Mercadona, Lidl and Aldi are not just any chains. They are precisely the ones that give the greatest prominence to their own brands. At least according to another recent study from Worldpannel by Numerator, which shows that if we talk about the weight of private labels in total sales, Lidl heads the list with 80.7%, followed by Mercadona (77.8%) and Aldi (74.5%). In summary: the chains that gained the greatest market share in 2025 were the ones that most clearly opted for their own products, a strategy that often arrives backed by aggressive price differentiation. elEconomista.es precise Furthermore, Mercadona, Lidl and Aldi have increased their market shares to record figures. Their 47.5% share is more than two percentage points higher than last year, when they accounted for a total of 45.2% of the market. Everything, they explain from Algori, while the entire sector experiences growth both in terms of volume and value. And what are the forecasts? The sector is optimistic. AECOC, the consumer association, states in one of its latest reports that 44% of companies expect to close 2025 with growth data above 5%. 28% expect to increase their activity, although to a lesser extent, and 11% expect to fall. They are led by Lidl and especially Mercadona, which has been expanding its market share until it approaches or even surpasses 30% thanks to a strategy based on white label, territorial dispersion and ready-made foods.

The James Webb captures a lonely object of the size of Jupiter devouring like a miniature sun

by

An international astronomer team has witnessed an extraordinary event: a lonely object, with a mass of just 5 to 10 times that of Jupiter, has entered a violent and prolonged growth burst. Using the combined power of James Webb Space Telescope (JWST) and him Vary Large Telescope (VLT) of the Southern European Observatory, scientists They have observed How this object, known as Cha J11070768-7626326, drastically increases its brightness and its “food” rhythm, behaving like a miniature star. The importance. This discovery represents the first time that a outbreak of accretion of type “exor”, a phenomenon so far associated with young stars, in a body of planetary mass. The finding is not only a milestone in astronomical observation, but also further blur the borders between what we consider a giant planet and a small star. The mystery. CH 1107-7626 is not a planet in the traditional sense that we all have in our mind. Although it has a mass comparable to that of a gaseous giant, I do not orbit any star and is 620 light years from the earth. Is what is known as an “free planetary mass object” or FFPMO (for its acronym in English). The existence of these lonely bodies raises a fundamental question for astronomy: are giant planets that were expelled from their solar systems, or are smaller stars that can exist in isolation? In order to solve this enigma that astronomers have right now on the table, you have to analyze the gas and dust disc that is around, as well as the way of accumulating the material. The fact that Cha 1107-7626 has an album and feeds on it suggests that its origin is more like that of a star. A cosmic feast. Astronomers observed Cha 1107-7626 in a state of calm in April and May 2025. However, for June, something had changed drastically. The object entered a “indulgence.” This means that its rhythm of ‘food’ began to increase, and in this way it reached a mass increase rate of 10-7 masses of Jupiter per year, the highest ever measured in a planetary mass object. As a result of this frenzy, the objective became between 1.5 and 2 brighter magnitudes in visible light and its optical flow increased between 3 and 6 times. This outbreak remained active for at least two months, since it was still on the end of the observation campaign in August 2026. But the most interesting thing is the speed it has. According to the observations made with the Vray Lark Telescope of the European Observatory, the growth rate is really aggressive, with a record rate of devouring 6,600 million tons per second of dust and gas. Great footprints. Beyond the increase in brightness, the telescopes captured detailed physical changes that reveal the nature of the event. A hydrogen emission line, known as Hα, developed a “double peak” profile with a red displaced absorption. According to the authors, this profile is a “distinctive brand” of the accretion channeled through magnetic fields, a process called “magnetospherical accretion” observed in young stars. But the most surprising finding was the change in the chemistry of the disc. At first, changes in the emission lines of the hydrocarbons molecules that came from the disc during the outbreak were seen. But water vapor also began to appear with a characteristic emission around 6.6 µm. This appeared during the outbreak where there was nothing before and is relevant because it is the first time that chemical changes of this type are observed caused by an increase in accretion. Relevance. This event classifies Cha 1107-7626 as the first “exor” of known planetary mass. Exor outbursts are significant accretion events that are considered key episodes in the early evolution of the stars. They can deeply affect the physical structure and chemical composition of the protoplanetary disk, potentially influencing the early stages of planet formation. Observing this process in such a small object demonstrates that the violent and fundamental mechanisms that the stars build also work at planetary scales. The study of Cha 1107-7626 offers an unprecedented vision of the accretion in the lower mass objects of the universe, providing a new window to understand how both smaller stars and the largest planets are formed.

We have a big problem with plastic. This caterpillar can help us devouring a bag in 24 hours

by

The global plastic crisis, a problem that It takes centuries to degradeI could find an unexpected ally in the world of insects. A team of scientists He has revealed how the caterpillars of the wax worm (Galleria Mellonella) are able to devour and metabolize polyethylene, The most common plastic in the worldat an amazing speed. However, they have a deadly cost for them. A decomposition that is not perfect. The investigation, presented at the Annual Conference of the Experimental Biology Societyreveals that these caterpillars, nicknamed “plastivorous”, not only chew the plastic, but that they decompose metabolically and make it an body fat in a matter of days. The most shocking data: some 2,000 caterpillars can end a standard polyethylene bag in just 24 hours. The problem of the plastic diet. Polyethylene is the plastic that we find in purchase bags, containers and endless daily use products. His chemical resistance makes it incredibly durable and, therefore, A persistent contaminant. The finding that a living being can decompose it naturally opens a Revolutionary door for waste management. However, the solution is not as simple as let out millions of caterpillars in landfills. Dr. Bryan Cassone, professor at the University of Brandon (Canada) and project leader, explains the great inconvenience: an exclusive plastic diet is deadly for worms. “They do not survive more than a few days with a plastic diet and lose a considerable mass,” says Cassone. It is as if a human swells with fat. The process is similar to that of a human consuming excess fat: The caterpillars turn the plastic into lipids that accumulate in their adipose tissue, but without the necessary nutrients to survive. It is not the first time that this possibility is explored. Given the seriousness of this problem, science does not cease in its attempt to find a solution to disintegrate the plastic we generate. Thus, in 2022 a group of Australian researchers They verified the ability of the ‘super worms’ to devour polystyrene thanks to an enzyme they had in their metabolism. But these same wax worms, object of this study, also They were already protagonists of an investigation where the capacity they had to decompose the plastic was proven. This study has taken a step further to perfectly understand its processing system and the repercussions it can have. Towards a sustainable solution: supplements and bioengineering. Although the fact that the accumulation of fat is an obstacle to research, scientists have turned this fascinating biological process into a viable solution already a large scale for pollution and for this they point to two main roads: create a mixed diet and replicate the process in the laboratory. Create a mixed diet. Scientists are experiencing with “co-supplement”, such as sugars and other stimulants, to mix with polyethylene. The goal is to formulate a feed that not only keeps the caterpillars alive, but to optimize their ability to degrade plastic, creating a circular economy system where waste becomes food. Replicate the process in the laboratory. The second way is even more ambitious. It consists of thoroughly studying biological mechanisms and intestinal microbiome of caterpillars to identify enzymes and bacteria responsible for the decomposition of plastic. If they get it, they could replicate this process of “biodegradation” in an artificial way and industrial scale, without the need to raise insects. And right now there are a lot of daily products that have been generated thanks to the use of bacteria, fungi or enzymes. In this way, the fact of extrapolating this process to the industry can be the most intelligent to control the management of plastics. From garbage to the plate. As if solving one of the biggest environmental problems were not enough, this research could have a positive and unexpected economic impact. The massive breeding of wax worms would generate a huge amount of insect biomass. According to Dr. Cassone, these worms could become a very nutritious food source for aquaculture. In this way, a waste as problematic as plastic could be revalued to enter a new value chain, contributing to the food industry.

A type of content is devouring all streaming platforms in silence: the anime

by

The Anime It became a large more ingredient of our cultural offer. No one is surprising that an anime feature film reaches the billboards, which is the second or third part of a saga that only the otakus knows but becomes The most watched premiere of the weekend. The anime has one of the most delivered and consistent fandoms in the world. It has nothing strange than the platforms of streamingalways attentive to any new success to which the tooth will have, have increased spectacularly in recent years their anime catalog fund. New mainstream. Since the first anime that triumphed in the West (‘Akira’, ‘Champions’, ‘Dragon Ball’, ‘Ranma’ …) decades have passed. The figures that manage the new successes (‘One Piece’, ‘Attack on the Titans’) show those of those productions, which already marked millions of young people in their day: now, generation Z is that of the anime, and its aesthetics and narrative have become the new new mainstream. That is, we are willing to review a few figures that define a cultural panorama dominated in large part by the anime. Crazy growth. The Parrot Analytics Market Studies firm Recently estimated that the average demand of the United States of anime in streaming It grew 176% between 2019 and 2024, and this is undoubtedly due to a greater amount of offer (in that period the number of anime programs tripled). But also to the increase of occasional spectators, which are those who are giving a renewed impulse to Japanese animation outside the fans circles. For the anime industry, all this means income from 27,000 million euros a year. A for the anime. A quick look at platform catalogs allows you to distinguish to what extent the anime is important in its programming. The first one is betting strongly on classics such as ‘Dragon Ball’ (licensed exclusively outside Asia the new franchise series, ‘Daima’) or ‘One Piece’, whose adaptation Live Action It has been one of the great successes of the platform in recent months. In the United States, in addition, Hulu (owned by Disney) plants face with abundant licenses, but out of there, in countries such as Spain, Netflix and Prime Video are distributed (they often share) the great successes: ‘Death Note’, ‘Guardians of the night’, ‘Naruto’ and many others. Specific services. And to this are added the dedicated platforms, a privilege of which only audiovisual subgenres with a more delivered fandom, such as terror or anime. In the case of anime we have above all to Crunchyrollwhich was born as a fan project in 2006 that spread anime without permission, but whose rapid acceptance led him to start closing deals with distributors to issue anime legally. Owned by Sony since 2021, he absorbed an important competitor, funimation, and has More than 120 million registered users. Other important streaming services exclusively of anime are Restrocush or Hidive, to which the abundant Fast thematic channels are added that emit 24 hours of series such as’ Pokémon ‘,’Conan detective‘ either ‘Inazuma Eleven‘. Everything is anime. Another important sign of how the anime has become undisputed creative force in current streaming is that many series that at another time would undoubtedly have had a western aesthetic approach now start from approaches completely anime: ‘Suicide Squad isekai‘It is produced in Japan and its own title betrays its origin, but is based on DC heroes; The greatest animation success of recent times, ‘Arcane’It is French production, but its anime visual roots are absolutely indisputable; And even a very characteristic series of the United States, ‘Rick and Morty’, has Your own spin-off anime. According to Jason Demarcocreator of the mythical Toonami thematic channel, this type of phenomena are a sign of “maturity” of this animation style. And all this rent extraordinarily in both addresses: 38% of international anime income is produced in Netflix. The benefit navigates In both directions. The new normality. The overwhelming growth and implementation figures in particular and Asian culture in general are no longer surprising (remember that a Korean series, ‘The Squid’s game’, remains the greatest success in Netflix’s history). That ‘Dundundun’ ravages or that one of the most profitable ideas that the platform has had in recent times has been to bring the anime in real image ‘One Piece‘They are some pieces of the many that make up a complex puzzle. One whose final snapshot shows a future in which the anime has an indisputable weight in the global computing of pop culture.
