We have been filling the refrigerator with kefir and high-protein yogurts for years. It turns out that the solution was invented in the year 874

by

For decades, the Mediterranean basin has held an absolute monopoly on nutritional health. They convinced us that olive oil, wheat and southern ferments were unbeatable. In the dairy aisle, this hegemony translated into the undisputed reign of Greek yogurt, a product that went from being a traditional food to becoming in the supermarket star thanks to its thick texture and high concentration of complete proteins. However, nutrition science has turned its sights toward much colder latitudes. Today, the undisputed protagonist of healthy diets, recommended by both sports nutritionists and metabolic researchers, does not come from Athens, but from Iceland. Is called skyrand although its appearance deceives us, it is rewriting the rules of what we consider a perfect breakfast. At first glance, the skyr It looks like some kind of ultra-creamy Greek yogurt, but it’s not technically a yogurt. Actually, it is about of a fresh, skimmed whipped cheese, made through a double fermentation process. From the Vikings to the supermarket shelf The history of this product begins with the first Viking settlements in Iceland, around the year 874. The Norwegian settlers who arrived on the island encountered an extreme climate and unfriendly lands. In that scenario, the skyr It became a real life insurance: a food ultra-concentrated in nutrients that allowed them to survive the harshest winters when there were hardly any resources. The traditional process starts with skimmed and pasteurized cow’s milk that is heated to 75ºC and cooled to 37ºC. Lactic acid bacteria are added to this base (such as Streptococcus thermophilus and Lactobacillus bulgaricus) and, crucially, rennet. After hours of fermentation, the product is carefully strained to eliminate the liquid whey. The result is a dense paste, with hardly any water, that requires three to four times more milk to produce than conventional yogurt. Today, the skyr has conquered supermarket shelves such as Lidl, Mercadona, Aldi or Alcampo. Nutritionist Blanca García-Orea points out that success in the supermarket lies in their clean labels: the best commercial options contain only two ingredients, pasteurized milk and lactic ferments, without added sugars or sweeteners. The clinical fascination with skyr It is based on its macronutrient profile. According to data collected by Healthlinea typical serving provides between 11 and 19 grams of protein, practically double that of a standard natural yogurt, while maintaining an almost non-existent level of fat (between 0% and 0.5%). But how exactly is it different from its direct competitors in the refrigerator? Nutritionist Laura Parada clears up the usual confusion between the skyrhe kefir and the yogurt. While the kefir stands out for a microbiota very diverse that includes yeasts and acetic bacteria, and normal yogurt It is based on lactic fermentation simple that leaves a light texture, the skyr It makes the difference because it is a fresh fermented cheese with a very high protein concentration and very thick texture. Added to this are other physiological advantages. The rigorous casting process of skyr eliminates approximately 90% of its lactose contentwhich allows many people with mild intolerance to consume it without experiencing digestive discomfort. At the micronutrient level, the portal Ingredia Food highlights that A 150-gram serving covers about 15-20% of the recommended daily intake of calcium, essential to protect against osteoporosis, and 19% of vitamin B2 (riboflavin), linked to the reduction of oxidative stress. What happens in your body when you eat it When you eat a tub of skyr, you’re giving your muscles exactly what they ask for. According to the magazine Nutrition & Metabolismits proteins are loaded with leucine and other key amino acids that trigger muscle synthesis. Basically, it’s an excellent tool for shielding lean mass when you’re looking to lose weight or prevent muscle from deteriorating with age. As if that were not enough, it takes away your hunger suddenly. The Aarhus University in Denmark did an experiment in 2024 pitting the classic breakfast of bread and jam against a bowl of skyr with oats. The conclusions of researcher Mette Hansen were resounding, the Nordic mix boosted mental concentration and satiety throughout the morning. Some women in the study were so full that they couldn’t even finish their portion. Science continues to find medical applications. Last year, the International Dairy Journal published a discovery very revealing about him skyr fermented with strains such as L. plantarum. It turns out that these formulations are capable of stopping blood glucose spikes after meals, while helping to reduce cholesterol and acting as a powerful shield against cellular inflammation. Not all the skyr it’s gold However, you have to put a magnifying glass on the shadows of any fashion product. That a container has the word printed skyr It does not make it a safe passage to comprehensive health. Magazines like Men’s Health warn that the industry is already marketing ultra-processed versions, such as ice cream skyrwhich although they provide protein, camouflage glucose syrup, fructose and added sugars in their ingredients. In addition, Healthline remember thatbeing made from cow’s milk, the skyr It is strictly not recommended for people with allergies to casein or whey protein, as it can trigger severe reactions. On the other hand, the debate about fat arises. Although the original version of skyr is applauded for being skimmed, a deep analysis that we did in Xataka We explain the historical demonization of dairy fat. Modern science is rehabilitating natural whole dairy products thanks to the “dairy matrix” (the membrane of the fat globule), which appears to have a cardiovascular protective effect and greater satiating power. This suggests that, although the skyr It is an excellent tool due to its protein density, completely dispensing with dairy fat in our diet based on ancient dogmas could be a mistake. The emergence of skyr in the global diet is not a marketing accident, but the convergence of an ancient tradition with the demands of modern metabolic medicine. Contemporary nutrition has stopped looking for shortcuts in laboratories to fixate on food matrices dense, real and fermented. Although it is not a magical food nor … Read more

It turns out that to innovate in mobile phones, only one thing was needed: (very) useful little things.

by

Neither the latest Qualcomm processor, nor “agent” AI, nor a camera with 200 megapixels. What surprised us most this week with the launch of the Galaxy S26 Ultra It was his anti-gossip screen. A friendly reminder that, perhaps, innovation in technology does not involve the most technical characteristic, but rather the most useful one. A touch of attention. We have been criticizing for years (and rightly so) that mobile phones do not innovate. For some time now, attending the presentation of a new model is usually summarized in: Same mobile Best camera (sometimes not even that) More power AI functions that, with a high probability, we will never use The umpteenth improvement in hardware that has been nearing its peak for years This is why, as soon as we see one of those novelties of the “oh, I want that in my daily life“, we return to that smile from when mobile phones were devices designed to make our lives easier, and not so much to sell hardware deployments at the highest possible price. The anti-peeping screen. Yes, we already know that there are €1 screen protectors that perform a similar function, but the point is that this screen includes it from the factory, and with brutal technology. It is capable of regulating the emission of the pixels so that we are only able to see the panel from the front. This opens the door to having a native security layer on our screen and, by the way, being able to put a quality screen protector on it (protection ones are usually not). The matte screen. A couple of years ago, Samsung surprised the world with the matte screen of the Samsung Galaxy S24an anti-reflective layer that represented a before and after when viewing content. Apple tried something similar in its last generation, but couldn’t come close. Once again, a silent innovation that did not impress on the technical sheet, but in terms of utility it was outstanding. Apple’s square sensor. People take selfies, lots of selfies. And turning the phone to do them is not a drama, but if you can save it, all the better. It is just what Apple invented with its iPhone 17 and the square sensor: one that allows the mobile to record and take photos both vertically and horizontally in the same position. NXTpaper screens. Although the superiority of the physical book over the electronic reader is a debate that I do not want to open (and that I do not intend to lose), TCL has been doing something for some time that its competition does not dare to imitate: dual panelswhich can be used as an electronic reader and as a traditional panel. How does it work? These phones and tablets are modified LCD panels with a different matrix than the rest. The backlighting system, the anti-reflective layer and the microtexture of the surface itself are adjusted to emulate an electronic ink panel, and thus be much less aggressive to the eye when we are reading. 10,000mAh batteries. Quietly, smartphone batteries are undergoing their biggest revolution. The main change: betting on silicon to give us much more generous capacities. Because yes, innovating is making the phone last three days, and not one as we have been accustomed to for years.

We have been reading philosophers from the West and Asia for centuries in search of the secret of happiness. Turns out the Aztecs had it

by

Each course Lynn Sebastian Purcell, philosophy professor, repeat the same experiment. After reviewing the passage from the ‘Odyssey’ in which Ulysses renounces an eternal life of pleasures with the nymph Calypso to search for his wife and son, the teacher presents a dilemma to his students: How many would do the same as the king of Ithaca? “How many of you would reject immortality and a pleasant existence on the condition that you never see your family and loved ones again?” defiant spear Purcell to the classroom. The answer is always the same: nobody. The ‘Odyssey’ is an epic poem that connects with the Greco-Latin tradition, but in reality that particular passage about Ulysses summarizes well the vital philosophy of a civilization that lived thousands of kilometers from the Ionian Sea: the aztec. Goal: happiness. I don’t know exactly who you are, but it’s quite likely that you, me and the more than 8 billion Of people who share this world, we agree that it is desirable to have a happy life. Logical, right? Happiness is one of those golden nuggets that philosophy has been searching for for centuries. I did it in times of Epicurus and he does it in our days. In fact one of the most famous treatises of Bertrand Russella famous philosopher of the 20th century, is titled with a phrase that is quite a proclamation: “The conquest of happiness”. The lesson of Ulysses. However, it is one thing to aspire to happiness and another to decide how to achieve it or even what exactly happiness is. This is where the passage from the ‘Odyssey’ of the nymph Calypso. If it’s just about seeking happiness, Ulysses already had it, right? If we agree that the goal is to be happy (just like that), isn’t it a good idea to spend an eternal life, free of illness and deprivation, living with a goddess on a distant paradise island? Why does Ulysses decide to return to the sea… and his hardships? “Let it be worth it”. Ulysses’ attitude (like that of Purcell’s students) connects fully with a philosophical ethic that for decades has gone unnoticed in the West: that of the pre-Columbian Aztecs. For them, remember the teacherwhat humanity really seeks is not so much a life full of happiness and pleasures as “an existence that is worthwhile.” That’s the goal. The texts that are preserved and tell us about how the Aztecs saw the world show that for them humanity faced “an existential problem,” In Purcell’s words: a brief, fickle existence, during which it is impossible to control everything just as it is not to skate in a quagmire. “Slippery is the land”. “What they wanted to say is that, despite our best intentions, our life is prone to error, failure in our objectives and, therefore, to ‘fall’, as if we were going to end up in the mud. Furthermore, this earth is a place where joy comes mixed with pain and setbacks,” explains the professor in an article published by the Philosophy Association (APA). In it he remembers that this entire conception of the world can be summarized in a popular saying: “Slippery, slick is the earth”“slippery, slippery is the earth.” Wait, Aztec philosophy? Exact. It has not been easy to survive and in the West we may not have paid enough attention to it, but that does not mean that the pre-Columbian Aztecs created a valuable philosophical corpus, with different currents and treatises. “We have many volumes of his texts recorded in his native language, Nahuatl,” claims Purcell at the BBC. “While few of the pre-colonial hieroglyphic-type books survived the Spanish burnings, our main sources of knowledge derive from the records made by Catholic priests until the early 17th century.” A different vision. Thanks to them we preserve codices with sayings, exhortations, poems, dialogues… different manifestations that essentially tell us about the same thing: how the Aztecs who lived between the 15th century and the beginning of the 16th approached existence. Good example is the ‘Florentine Codex’a bilingual work by friar Bernardino de Sahagún on pre-Columbian knowledge. His legacy is not only interesting because of what he tells us, it is also interesting, Purcell claimsbecause it opens our eyes to “another pre-modern culture with an ethics of virtues”, one different from the legacy of Aristotle or even Confucius. “Place of joy with fatigue”. At this point the question is obvious… If the Aztecs believed that what humans really want are lives “worthwhile”, even more than joyful and pleasant existences, how to achieve it? How to face the passage through this world, “a place of joy with fatigue and pain”, as an Aztec passage says? The key is in a recipe with four ingredients, four “levels” that allow us to enjoy a rooted life, “neltiliztli”. Continuing with the metaphor of existence as a swampy terrain, full of mud, the idea is to take root to gain a foothold. And how to achieve it? To begin by ‘rooting’ in one’s own body. As Purcell explains, the figurines and descriptions we preserve of the Aztecs show us that they liked to exercise their bodies. In fact, they had a regimen of activities aimed at stretching and strengthening the body that is partly reminiscent of yoga. Rooted in the body, it had to be done at another level: the “psyche”, seeking a balance between the heart and the head, desires and judgment. “Only in the middle can you go, only in the middle can you live”, advises one of his works. Social creatures… and of the earth. In an article Published years ago in Aeon, the scholar of Latin American philosophy points out two more levels at which those who want to achieve a rooted life must work, “neltiliztli”, a term that is also used as “truth” and “goodness.” The first level is “rootedness in the community.” We live surrounded by people, in societies in which we play a role that connects us with others and activates the … Read more

the dangerous viral trend that turns a common medicine into a lethal Russian roulette

by

Something that may be quite internalized in society is that taking too much of a medication Anyone can have a very harmful effect on the body, and logically we avoid taking a lot of ibuprofen or paracetamol at once. But social networks have taken this as a new challenge which consists of taking paracetamol pills in a group to see who can achieve spend more time admitted in the hospital due to the liver failure it generates. Crazy. What has been dubbed the “paracetamol challenge” on social media is becoming a real nightmare for emergency and toxicology services. And it is no wonder, since behind the false sense of security that an over-the-counter medication such as paracetamol gives, hides a mechanism of implacable toxicity capable of destroying the liver of a teenager in a matter of hours. At an international level. The phenomenon is not new, but it has raised alarm bells internationally due to its recent outbreaks. In the United Kingdom, newspapers such as The Independent have been echoed of police warnings after registering cases of teenagers intentionally intoxicated in Soutampaton due to this challenge. And, although the first thing you might think is that it is a suicide attempt, since paracetamol is one of the ways used to do it, the reality is that they do it because of a challenge seen on TikTok. This too has reached countries like Belgiumwhere health authorities have had to launch a strong alert about videos that encourage people to overdose on this medication. In Spain. Has not been left behind our country, which has also reported cases of adolescents who have followed this challenge. But to such an extent that in Malaga There have been two hospital admissions due to liver failure due to a drug overdose. The paracetamol trap. Although it is a medication that can be found over the counter, in the case of Spain, generally the dose is 500 mg, the truth is that it has a great danger behind it, since paracetamol overdose is one of the most frequent and potentially lethal pharmacological poisonings. But the great deception of this challenge is that symptoms of poisoning do not occur in the first hoursbut a teenager can ingest several grams of acetaminophen and feel at most mild nausea or vomiting. In this way, while the young man thinks that “nothing has happened” and that he has won the challenge to his friends, the liver is silently collapsing. In days. International clinical guidelines place special emphasis on this: late liver deterioration, since the symptoms of severe liver failure appear only three days after taking the paracetamol overdose. And here on many occasions it is too late to act from medicine, which causes the death of the patient. The mechanism. Playing the “paracetamol challenge” is, in medical terms, playing Russian roulette, since massive intake of this drug saturates the metabolic pathways of the liver, generating a highly toxic metabolite called NAPQI that destroys liver cells when in large doses. With a normal and scheduled intake, this metabolite is produced, but the liver can control it by transforming it into another product that it quickly discards. But when the amount is very high, the liver literally has no capacity to process it into something less harmful. The treatment. Right now, the only thing that has shown a reversal of liver damage from acetaminophen overdose is N-acetylcysteine. However, the effect decreases as time passes, and it is ideal to administer it in the first eight hours after an overdose with paracetamol. The problem is that the teenager can hide that he is beginning to feel bad because he has a feeling of guilt or even fear of the consequences that his actions may have on his parents. This is why it may be the case that you arrive late to a hospital to receive treatment and that the window available to do a stomach lavage or even for a liver transplant to arrive is very small. Raise awareness. The “paracetamol challenge” is not just another Internet hoax, but rather it is a direct fight against the biology of the human body in which the prize for “lasting longer in the hospital” can be multiple organ failure or ending up on the waiting list to receive a transplant. In this way, the most important thing is always to make minors aware of how serious it can be to take too much paracetamol, since it is possible that they do not know that something that a priori ‘cures’ their fever or discomfort can end up killing them.

Since we were children we have been told that Jupiter is enormous, colossal, exaggeratedly large. Turns out not so much.

by

There are things that we learn in childhood that accompany us throughout our lives and one of them is to recite the Solar System at once, which has its disadvantages: for those of us who are already old, mentioning Pluto (which It is no longer a planet) either make mistakes when estimating distances interplanetary. Another classic misconception is the size of Jupiter. Data from the Juno mission published in Nature Astronomy They change the shape and size of the colossus of the Solar System. Jupiter is flatter and smaller than we thought. We knew that Jupiter was the largest planet in the Solar System, a gaseous colossus whose mass exceeded that of the rest of the planets combined, which gave it the power to be almost the conductor of the orchestra (with the permission of the Sun) as long as its gravity had a lot of weight. Its large magnetic shield protects its moons from solar radiation, it has iconic clouds and storms in astronomy and its Great Red Spot It exceeds the Earth in size. But there is something wrong with its shape and size. The Context. The missions Voyager and Pioneerdating back to the 1970s, established figures that today we read in science books: that Jupiter has an equatorial radius of 71,492 kilometers and a polar radius of 66,854 kilometers. With this model, the planet was assimilated as a sphere flattened at the poles (oblate spheroid). These dimensions were calculated with just six indirect measurements with profiles of radio occultation. The discovery. Because what Juno has seen shows that the equatorial radius is approximately 8 kilometers smaller and the polar radius is about 24 kilometers smaller than previous missions said. Qualitatively, Jupiter is flatter. The first thing that comes to mind is: How important are eight kilometers on a planet 140,000 kilometers wide? Well scientifically, it has it. In fact, it’s the difference between whether the laws of physics fit or not. Why is it important. Well, because although the difference is comparatively minor, the fact that it is smaller and has a flatter shape has thermodynamic implications. Thus, it suggests a colder atmosphere enriched with heavy elements that better suit what the Galileo probe measured in 1995. Additionally, having accurate geometry is essential to understanding what’s inside and interpreting the gravity data provided by Juno, so we can accurately map how its mass is distributed inside and how hydrogen behaves under extreme pressures. On the other hand, knowing Jupiter better is getting closer to the recipe of how the Earth was formed and going beyond: facilitating the understanding of thousands of other exoplanets giants that we are discovering in the stars. Radio occultation operation diagram. MPRennie Wikipedia Juno’s look. Both Pioneer and Voyager and Juno use radio occultation, that is, they use the same physical principle. The radio occultation technique consists of measuring how a planet’s atmosphere bends and slows down the radio signals of a probe when it is hidden behind it. By analyzing the delay and deviation of these waves from the Earth, the scientific team can precisely calculate the density and pressure and therefore the exact shape of the planet. Of course, from a technological point of view there has been half a century of evolution and it is noticeable in terms of quality due to its multiband operation, precision and repetition. Thus, the probes of the 70s mainly used one radio band while Juno uses two, which allows, among other things, to eliminate noise. Likewise, the original ones were passing missions in front of the planned June orbit, that is, we have gone from having six points to an almost complete map. And finally, ground-based tracking systems are night and day when it comes to measuring changes in frequency and signal arrival time.

The world is amazed by Moltbot (formerly Clawdbot). It turns out that China had already invented it almost a year ago

by

The phenomenon of the end of January has been Molbotformerly known as Clawdbot. It is one of the AI agents most powerful of the moment, to the point that it warns of its own risks even before being installed. An agent who seemed to have no competitor and to be one of a kind. We were wrong. TARS-1.5. Although it has not made as much noise, in April 2025 it was launched UI-TARS-1.5an open source multimodal agent capable of performing all types of tasks within desktop environments. UI-TARS-1.5 is a multimodal agent designed to interact with the digital world through graphical interfaces, using the screen, mouse and keyboard. It came into the hands of Bytedance, a company behind giants like TikTok and one of the main players in the development of artificial intelligence in China. The difference. 1.5 is an AI agent designed to use a computer as a person would do. See the screen, identify visual elements and act using mouse and keyboard. Unlike Moltbot, it does not execute code or commands directly on the system, but rather interacts with the PC from the outside, at the interface level. It’s safer by design, because you can’t break the system by running arbitrary code. In addition, it reasons before each action, which reduces errors accumulated in long tasks. UI-TARS does not control your computer. He uses it. Moltbot does not use your computer. He controls it. What can you do? UI-TARS interacts “talking” with your computer. It is capable of executing tasks in our interface by analyzing what is in it. Serves as a programming assistant. It can behave like a human to test apps. It works as a tutor to perform complex tasks. You can manage desktop tasks and PC management. Why is it important. The new war for AI will not focus exclusively on models like Gemini, ChatGPT or Claude: the next step is to achieve a local AI capable of acting like a human, but with certain security guarantees. Moltbot, UI-TARS, Kimmi K2.5 (also Chinese)… Although agentic AI sounds distant, the war to make it part of our daily lives has been brewing for years.

Tesla turns on the mega-refinery in Texas with which it wants to break China’s game

by

The map of global power is no longer drawn only with oil wellsbut with the critical mineral pathways. In a move that redefines the auto industry and energy geopolitics, Tesla has announced that its lithium refinery in Texas is already an operational reality. It is not just another factory; It is the West’s first major attempt to wrest the keys to 21st century mobility from China. The advertisement. tesla sent a strong message through its official channels: its lithium refinery is now operational. According to Elon Musk himselfthis milestone “marks the beginning of energy independence for North America.” The facility, located in Robstown, near Corpus Christi Harbornot only seeks to ensure the supply of components, but also to reduce logistics emissions and generate regionalized employment. As detailed by Spectrum Newsthe plant has met the ambitious deadlines set since it was launched the first stone in May 2023. What was then a project of more than 1,000 million dollars, today is, according to Musk’s wordsthe largest and most advanced facility of its kind on the continent. A look towards China. To understand the magnitude of this step, you have to look at the Asian giant. Tesla is replicating the successful strategy of the Chinese giant BYD: absolute vertical integration. It’s no longer just about designing software or assembling chassis; it’s about controlling the entire value chainfrom when the mineral comes out of the ground until it becomes a battery cell. The capacity of this plant is massive. According to the specialized media DiscoverAlertthe refinery has a capacity of 50 GWh per year, which translates into enough lithium to manufacture approximately one million battery packs per year. By eliminating intermediaries, Tesla not only ensures its production rate, but also shields itself from the frailties of global logistics and geopolitical tensions. Texas alchemy. The real revolution of this plant is not only its size, but its chemistry. As Jason Bevan explainsmanager of Tesla, the plant uses a pioneering process in the United States: alkaline leaching to directly convert spodumene mineral into lithium hydroxide suitable for batteries. Unlike traditional refining—which often relies on aggressive acids and generates hazardous waste such as sodium sulfate—Tesla’s method is acid-free (acid free). As the refinery staff explains in the official video released by the brandthis process eliminates toxic byproducts. Instead, it generates a mixture of sand and limestone known as “anhydrite.” This byproduct, far from being waste, is being integrated into the circular economy. tesla confirmed from the beginning of the project that this material would be used in the production of construction materials (concrete), turning a traditional waste stream into a useful resource. Is it possible to break away from China’s shadow? Despite the optimism in Texas, the reality of the global market remains overwhelmingly favorable to Asia. How we have developed in XatakaChina currently controls the refining of 19 of the 20 strategic minerals evaluated by the International Energy Agency (IEA). Their dominance is almost total, since they process 95% of the graphite and 98% of the rare earths on the planet. Furthermore, the Chinese advantage is not coincidental, but the result of decades of investment under the “Made in China 2025” plan. While Tesla has managed to build its refinery in a record time of 19 months, the IEA warns that, on average, a mine takes up to 17 years to be operational. However, the United States has begun to play its cards with unprecedented aggressiveness. According to OilPricethe US administration has moved from traditional lending to direct involvement, acquiring stakes in mining companies such as Lithium Americas. This paradigm shift seeks to close the gap with China through public-private collaboration that includes massive projects such as Thacker Pass in Nevada, which is expected to be the largest lithium supply in the Western Hemisphere by 2027. The mining ecosystem: from Nevada to Texas. Until now, lithium production in the United States was almost negligible. According to a CNBC report, the Silver Peak plant in Nevada, owned by Albemarle, has been the only active source in the country for decades. Their method, based on solar evaporation in giant pools covering 13,000 acres, is a slow process that requires 18 to 24 months to concentrate the mineral. The arrival of Tesla and other players such as American Lithium (which recently expanded its assets in Nevada according to their own corporate statements) is transforming the sector. While Albemarle focuses in the extraction of underground brinesTesla focuses on the refining of hard rock (spodumene), creating a diversified ecosystem that seeks to feed the growing demand for electric vehicles. A change of era. The success of the Texas refinery will not be measured only by the tons of lithium hydroxide it produces, but by its ability to demonstrate that the West can compete on costs and sustainability without depending on Chinese infrastructure. Tesla isn’t just making electric cars; is building the foundations of industrial sovereignty. This project is the first concrete step to reduce a dependency that until recently was considered inevitable. Time will tell if 19 months of Texan engineering can beat two decades of Chinese strategy, but, for now, Tesla already has one of the keys.

100% robotic plants where not even the light turns on

by

The automobile industry is going through a moment of evolution that we are all very aware of, especially in the face of the energy transition which we are witnessing. China is shown as a reference country in this technological revolution and its manufacturers are demonstrating it with a multitude of models that lay the foundation for the present and future of the automobile. Not only is there a technological revolution in many of the vehicles we see on the streets, but also in the manufacturing process of them. And before the end of the decade, at least one manufacturer will achieve a fully automated assembly line. This is the conclusion to which they have arrived analysts at Gartner and Warburg Research. China leads the race to inaugurate the first “dark factory“, factories where robots work without the need for lighting or human presence, which could forever change how cars are manufactured. Below these lines we tell you all the details. Why it is important. It is not just about robots replacing people in specific tasks, but about the total elimination of workers on assembly lines. China already has a wide range of “dark factories”factories with assembly lines where there is hardly any lighting and are operated by autonomous robots. However, car assembly has not yet been 100% automated, since the process still requires human hands. This would mark a turning point where artificial intelligence, humanoid robotics and digital manufacturing converge to redefine automotive production. Pedro Pacheco, research vice president at Gartner, account to Automotive News Europe that a U.S. or Chinese manufacturer will “likely be the first to create a line with 100% automation by the end of this decade,” and that several players in those markets “are already implementing disruptive manufacturing processes and showing more focus on humanoid robots.” Robotics and redesign. Until now, the installation of wiring and cockpit components have been the only elements of the assembly line that are not normally fully automated, explains Pacheco. From the media they say that manufacturers that make the leap towards total automation will do so through two routes: adding advanced robotics and redesigning vehicles to facilitate automated assembly. Automotive News Europe mentions splitting the wire harness into sections or integrating it directly into the body panels as an example. Another strategy is to not completely assemble the “body in white” before assembling the passenger compartment, thus facilitating access to the passenger compartment. The protagonists of change. Hyundai Motor Group plans to deploy humanoid robots from Boston Dynamics at its Georgia manufacturing complex starting in 2028, according to advertisement at CES in Las Vegas. The South Korean company aims to produce 30,000 robots per year and achieve production-scale deployment. Mercedes-Benz, for its part, has launched a pilot project with humanoid robots that could start working alongside assembly line employees before 2030. And Tesla is already manufacturing their optimus robots on a limited scale in California, with Elon Musk’s vision of creating an army of robots that help in his factories and take on other tasks that involve repetition of processes. Figures. According to Accenture, the integration of generative, agentic and physical artificial intelligence with robotics and digital twin technology it helps to significantly improve factory efficiency, with “enormous potential” to reduce costs and time to market by up to 50% or even more. McKinsey duck that $150 billion annually in potential economic value could be unlocked by accelerating R&D at large auto companies. Additionally, 12 of the top 25 manufacturers are already running pilots with advanced robotics in their facilities, according to they shared from the analysis firm Gartner. The debate on employment. Full automation does not necessarily have to translate into massive job lossesalthough it is certainly an issue that causes concern in unions. Workers could be reassigned to support functions such as maintenance, engineering, logistics, inspection or materials management, according to Pacheco. With proper training, employees could also engage in AI supervision, robotics maintenance, and software development. The International Labor Organization anticipates that, although some routine and manual tasks will be reduced, many positions will change their content and new jobs will emerge. And now what. China is the favorite to inaugurate the first completely robotic factory, but everything indicates that the United States is not going to be left behind either. Warburg Research analyst Fabio Hölscher consider that it is “not unrealistic” to expect to see the first automotive “dark factory” in China by 2030.

If we go back to 2009, many of us will remember a program known as The Deadliest Warrior (Deadliest Warrior). The premise was to pit two combatants from different eras against each other to see who would win in a duel to the death. Although on the screen we saw the Viking measure his axes against a Samurai, and the Gladiator against an Apache, we never got to see the direct duel between the colossus of the north and the warrior of the Mediterranean. That “fight of the century” was left hanging on television, but in the field of nutrition, the Roman side (the Mediterranean diet) has been the undefeated champion for decades. However, science has decided to simulate that combat in the laboratory in 2025, and this time the Viking’s ax has nipped Mediterranean leadership in the bud. According to the latest studies, the Nordics have a much better solution. A new discovery. Given that we live in the Mediterranean area, it seems impossible to do without olive oil and wheat. But, as nutritionist Dawn Jackson Blatner explains in National Geographica “cousin to the Mediterranean diet in colder climates” has emerged that is demonstrating surprising results. Originally created in 2004 by a committee of scientists and chefs—under the premise that health is not incompatible with gastronomic pleasure—the “new nordic diet” It does not seek longevity, but rather does so with a focus on local sustainability that the Mediterranean model often ignores outside its borders. The most recent milestone is the study published in Frontiers in Endocrinology. After analyzing a young and middle-aged population, researchers led by Abdelgawwad El-Sehrawy found that those who strictly follow the Baltic Sea dietary pattern have a 42% lower risk of developing type 2 diabetes. If the strictest adherence index is used, protection rises to a staggering 52%. This finding is crucial because it shows that the benefits act as a preventive shield from youth, and not only in old age. A shield against modern diseases. The robustness of this diet is supported by an “artillery” of previous research that already pointed in this direction. As a 2024 study details published in Scientific Reportsthe Nordic diet is one of the best tools to combat non-alcoholic fatty liver, reducing its risk by 58%. Added to this is that the benefits do not remain in the metabolism. According to a 2022 meta-analysis published in Diabetology analyzed data from more than a million people, confirming that those who follow this lifestyle have a 26% lower risk of dying from cardiovascular disease, a 22% lower risk of premature death from any cause, and a 14% lower chance of dying from cancer. As Dr. David L. Katz states“all good diets are made up of real foods, mostly plants; the Nordic diet is a masterful variation on that same theme.” What does it mean to eat like a Nordic? Many will surely have thought that it would be something like “eating aranques every day”, but (happily) it is not like that. The mainstay is canola (rapeseed) oil, rich in omega-3 fatty acids and more affordable than olive oil, along with: Whole grains: Rye, barley and oats (essential due to their low glycemic index). Forest fruits: Blueberries, raspberries and wild berries. Tubers and cruciferous vegetables: Beets, carrots, cauliflower and cabbage. Fatty fish: Salmon, mackerel and herring. Fermented dairy: Like skyr or kefir. Beyond diet. One of the points to highlight about the diet is that, according to research by British Journal of Nutrition, Women who followed the Nordic diet reached old age with significantly greater physical performance, easily passing walking and strength tests. The Nordic diet has an ‘inevitable’ side effect: weight loss. And it does this by hacking the feeling of hunger. The NORDIET study put to the test to subjects with high cholesterol and the result was a drop in weight and blood pressure without the stress of measuring each gram. But the most compelling data came from the NND trial. in The American Journal of Clinical Nutrition: Participants with abdominal obesity lost an average of 4.7 kg by eating on demand, without quantity restrictions. Compared to the few kilos lost by those who followed a normal diet, the Nordic system appears to be much more efficient. A solution for everyone. What the north teaches us is that health is not the exclusive property of one geography. As dietician Joan Salge Blake points out,the success of this diet lies in its ability to add strength. It’s the mix of fiber, healthy oils and antioxidants that really matters, acting as a balm against inflammation. It is there, in that inflammation that fuels the diseases of our century, where the Nordic diet fights and wins its most important battle.” You don’t have to live in Oslo to benefit. The key, according to experts, is to prioritize whole foods, choose fatty fish (even if they are frozen or canned due to their affordability) and replace white bread with whole rye. The Nordics seem to have found the recipe for a long, strong and sustainable life. In 2025, the fight is over: the Viking knows how to take better care of himself.

There is a startup that turns the ashes of your dead into stones. And he is charging more than 2,000 euros for it

Cremation is an increasingly common practice after a death and it is not uncommon for many families to keep the ashes or spread in special places. There is a company that has had an idea to turn the remains of our loved ones into a new object: stones. Parting Stone. It is the name of a startup founded in San Francisco that is dedicated to solidifying the ashes of dead people and shaping them into soft, rounded stones. Justin Crowe, the founder, told in a interview with the Wall Street Journal that people usually keep ashes in any closet because it is not something we feel comfortable with, but when transformed into these stones they become a kind of amulet without that negative connotation. “Some families travel with the stones, share them with friends and loved ones, children paint on them; some people keep them in their pockets and even sleep with them under their pillow,” he says. First tableware. that the idea was born after his grandfather’s funeral, a traditional ceremony that made him feel uncomfortable at such a vulnerable moment. After the experience, Crowe began to think about how he could create something new for the grieving process and first came up with an idea: mixing ashes with ceramic glazes. He created tableware with this technique and began to receive orders, the problem was that to make it he only used a small amount of the ashes and he wanted to create something using more. Solidification. The process to turn ashes into stones is quite simple: refine them to a fine powder, mix them with water, shape the stones and cook. Normally about 40-80 stones come out of the ashes of an adult person and they warn that the color depends on each person. The service costs $2,495 for people and $1,195 for cats and dogs, so that’s nothing. The business of ashes. Cremation is a practice increasing around the world. According to Crossing World Group data, This year in Spain, cremation has surpassed burial for the first time, so these types of initiatives are increasingly common. In Spain there is a company called Omneo that turns ashes into a block of wax with an NFC tag. There are also companies that convert ashes in diamondsin trees and even in coral reefs. The most striking proposal of all is that of the Barcelona company Giem Sportswhich proposed the management of spaces within football stadiums to store the ashes of fans. Betis inaugurated a space of this type and they charged 3,000 euros to keep the ashes for a period of 99 years.
