College students are rapidly losing a critical skill: reading.

My students can’t read. It is the title of the opinion column in which Tyler Jagtuniversity literature professor, narrates the situation currently found in his classrooms. Many students are not able to read or maintain the plot of a 20-page text. He believes that AI and mobile phones are to blame. 20 pages is too much. This teacher says that he has been assigning the same task to his rhetoric and writing students for five years: reading a 20-page article. However, this year none of his students finished the work and they were not repeaters, but rather university students who had passed the entrance exams. One of them was honest and admitted that the text was too long and “constantly missed the point of the article.” Jagt acknowledges that the complaint that students do not know how to read is common among teachers, but according to him this time things are serious and there is data that corroborates it. The tests. According to the results of the 2024 National Assessment of Educational Progress (NAEP), students in grade 12 (equivalent to a 2nd year of Baccalaureate in Spain) obtained the lowest score on the reading test since the assessment began in 1992. A third of the participants reached the basic level, which means that they are likely not able to “draw general conclusions based on concepts explicitly presented in a text.” Younger students are even worse off. According to a study by the Annie E. Casey Foundation70% of fourth grade students (like fourth grade) are not able to read fluently. That is in the United States, but in Spain the situation is not ideal either. According to the OECDat least a third of the Spanish population has level 1 reading comprehension, which means that “they can only understand very short texts with a minimum of distracting information.” A report from the BBVA Foundation and the Valencian Institute of Economic Research (Ivie)Spaniards between 25 and 34 years old, who have studied more than their parents, advance much more slowly in basic skills. It’s technology’s fault. Or at least that is what the author maintains, specifically the emergence of smartphones and, more recently, AI. The idea that technology makes us stupid has been accompanying us for decades and with the emergence of AI, technological panic has intensified. That students are using AI to do their jobs is something we already knew. What is still not clear is what consequences it can have on a cognitive level. There is no evidence that technology produces cognitive damage (yes changes), but it is also true that until now we have not had a technology capable of doing everything that AI does. Debt and cognitive surrender. They are two concepts that emerged from recent studies. The first, cognitive debtcomes from a MIT research titled “Your brain on ChatGPT”. Participants who used ChatGPT had the worst brain performance when completing a task that involved writing essays. The researchers conclude that using AI as a complete substitute for mental effort can weaken our neural connections. The idea of cognitive surrender is mentioned in a recent study from the University of Pennsylvania. According to researchers, cognitive surrender arises when we delegate our thinking to AI and accept its answers too confidently. Another study from the University of Oxford saw how If we use AI and then it is taken away from us, our performance worsens. not so fast. There is an important nuance and that is that the concept of “using AI” is very varied. We can use it without checking the answers and accepting everything it tells us or we can use it as a tool in our creative process. In fact, in several of these studies, participants who used AI as support obtained scores very similar to those of the group that did not use AI. Therefore it is not whether we use it or not, it is how we use it. However, the arguments in favor of using AI in educational environments are becoming fewer and fewer. There was a study that said using chatbots like ChatGPT had a positive impact on learning, but was recently withdrawn due to “concerns regarding discrepancies”. Come on, the biggest argument of the defenders of educational AI went down the drain. The other culprit. As we said, this professor also points to smartphones as responsible for this situation. Appointment a 2017 study in which they verified how the simple presence of the mobile phone reduced the “available cognitive capacity”. He also cites another 2022 study in which they saw that reading on a smartphone was associated with prefrontal overload and decreased concentration. Tiktokize the school. The problem is not cell phones, but social networks and doomscrolling that hijacks our attention. We have become accustomed to consuming pills of information in the form of tweets, posts, reels and tiktoks. In this context, a 20-page text is much, much. Tyler Jagt is adapting to this reality by dividing work into two, so they have to read less, and assigning specific tasks so they don’t lose track as much.

Spain is rapidly stopping consuming it and no one has convincing explanations

There was a time when many things could be missing from the tables of Spanish homes, but never bread. Never that. The bar was an essential part of the diet, one of its pillars, so firm that it even ended up leaving a mark in the proverb. Things have changed and now it is increasingly difficult to find bread in homes at meal time. And for example, a button: its per capita consumption (at least domestic) has collapsed in the last decade. The big question is… Why? Less bread at home. On Spanish tables and cupboards it is increasingly difficult to find loaves of bread. Although for a long time they were one of the pillars of nutrition (so much so that it has crept into popular proverbs), households seem to be turning their backs on them little by little. And no one really knows why. The last reminder of the extent to which we have lost interest in bread was left yesterday by the EfeAgro agency in a chronicle which starts with a revealing fact: on average a Spaniard consumes 25% less today than just a decade ago. Has consumption dropped that much? To answer that question, it is good to take a look at the data from the Ministry of Agriculture, Fisheries and Food. To be more precise to the figures of your consumption panelin which they detail “the food consumption data in Spanish households.” The nuance is important because its results basically show domestic behavior, purchases and consumption that are made within the home, not in the extradomestic channel. When the data on bread is analyzed, the reading is clear: today we consume less (much less) than a few decades ago. And as a figure always says more than a long explanation, here is a table with the evolution of demand. The data show annual per capita consumption measured in kg, although one detail must be clarified: the concept “bread” has remained unchanged in the historical series, but not its different classifications, which have changed, combining concepts such as “fresh bread”, “unpackaged” or “industrial bread” and “packaged”. Bread (total) fresh bread industrial bread 1990 56.4 52.9 3.5 2000 50.1 46.4 3.7 2010 36.3 30.8 5.5 2020 32.8 26 6.8 2024 27.4 21.5 5.9 looking back. The drop is even more pronounced if we broaden the focus and look at how Spaniards behaved in the 60s and 70s. Although the calculation criteria may have varied, the data from the Ministry of Agriculture show that in 1964 the “consumption of bread-making cereals in Spain” was around 92.5 kg per inhabitant per year. In the 70s that average was already 76.6 kg. He latest yearbook published by the Government, with data at the end of 2024, show that total per capita consumption of bread fell in the country by 0.2% compared to the previous year, although this decrease was not generalized: consumption of normal fresh bread ‘punctured’, while demand for whole grain, unsalted and industrial bread grew. Is it all negative data? No. Recently the Ministry of Food published a report with data from the year between August 2024 and July 2025 showing that bread purchases have generally increased by 3.9% during that period, leaving annual per capita consumption at 27.8 kilos. It remains significantly below the 34.9kg 2015, but it still represents an increase. Bread can also boast of having an almost absolute level of penetration in Spanish homes, reaching more than 99.8%, and generates a business of billions of euros. To be more precise, the data accumulated between August 2024 and July 2025 speak of 3.4 billion. Searching for the causes. The big question at this point is… Why do we consume less bread at home today than a few decades ago? EfeAgro remembers that in the last ten years its price has become more expensive almost 29%although the CPI data for September show that at least in the last year it remained below the general price index: 1.2% compared to the global 3%. The drop in consumption seems to respond more to changes in consumption habits: a greater availability of alternatives to bread, a more varied diet, a increase in consumption in places outside the home… “There has been a downward trend for years in Spain, it must be taken into account that when societies become more prosperous, consumption is reduced and other sources begin to be used”, explained already 2022 to The Spanish Jorge de Saja, from the Spanish Association of the Bakery, Pastry and Pastry Industry. Another key point from the sector is the increase in more satiating variants (such as whole wheat). “Don’t eat bread”. There are those who provide another explanation for the drop in bread consumption: “The perception that it is a food that can make you fat,” they regret from Asemac. Ángeles Carbajal Azcona, from the Department of Nutrition at the Complutense University of Madrid, also remembered it in 2016 in an article in which, citing other authors, I remembered that the “dietary advice” of some specialists to lose weight is: “Don’t eat bread.” “Epidemiological studies that try to look at the relationship between bread consumption and body weight usually see that people who consume bread more frequently have a higher risk of obesity, diabetes and weight gain,” he clarified in 2024. Jordi Salas-Salvadóprofessor, a The Country. “The problem is that these studies are done with current bread, which is not the same as traditional bread, with sourdough and long fermentation: bread has a high glycemic index, but artisanal bread has more fermentation process and that makes the glycemic index lower.” Image | Diana Krotova In Xataka | “We are the glitch in the Matrix of food”: the Madrid bakery whose reinvention of bread has gotten out of hand

The magnetic north pole has been moving rapidly. This is how navigation instruments follow the step

What do we talk about when we talk about the North Pole? The truth is that it depends since, on our planet we can distinguish two key geographical points that respond to this name, but with different “surname.” They are the magnetic north pole and the geographical north pole. Distinguishing them is key because only one of them has a fixed location while the other wanders in their proximity. But, in addition, it makes it faster. Reviewing the location. The new year has been released With an update that has gone more or less unnoticed but that is of the utmost importance: it is the world magnetic model (WMM) of 2025. The revision of the model not only includes the information about its current position but also of its displacements planned in the next five years . Accelerated movement. We have known for a long time that the magnetic north pole changes location and we know that the cause is in the changes in the magnetic field of the planet, a field generated by the connective iron movements of the interior of our planet. What is most striking is that, during the last decades the displacement of the magnetic northern pole It has accelerated. If for 300 years this point ranged between the islands located north of Canada, since the end of the 20th century and especially during the new century, the speed of displacement of this markedly accelerated. Now the magnetic north has already exceeded the geographical north and is closer to Siberia than from Canada. “The current behavior of the magnetic north is something we had never seen before. (…) In recent years he accelerated towards Siberia, increasing speed every year until about five, when he suddenly seized 50 to 35 km per year, ” explained in a press release William Brown, of the British Geological Survey (BGS), one of the institutions in charge of the development of the model. The world magnetic model. The model It is the result of the collaboration between the National Environmental Information Centers (NCEI) of the NOAA (National Oceanic and Atmospheric Administration) American and the BGS, as well as two intelligence agencies on both sides of the Atlantic. The model is used in various contexts, from aviation to commercial GPS and applications that use compasses on our mobile. The model includes a series of maps that not only indicate the location of the magnetic north but also mapped the changes in the Earth’s magnetic field, allowing to know the behavior of compasses at each point of the northern hemisphere. More precision. The latest version of the model, WMM2025will help improve navigation, especially in long -distance tours. As explained by the BGS, a trip between South Africa and the United Kingdom, using the old model, would imply a slight deviation of a degree on the way. The problem is that, over 8,500 kilometers, this very small deviation results in an error of 150 kilometers. The new model allows you to approach centimeters from the destination point. The version also incorporates a novelty: a high resolution map that will accompany the “standard” and that can be used in contexts where greater precision is required. This version has a 300 km resolution in Ecuador, notably higher than the 3,300 km resolution in the standard version. The next update. The WMM model is updated every five years, which means that we will have a new version in 2030, WMM2030. This assuming that I do not know any unexpected change in the speed or direction of the displacement that justifies an extraordinary review of the model.
