China is attending a crazy race to demonstrate who has the safest battery. That’s why they crush them with tanks

by

If I point to the volume, I am not sure if I learned a lot or little in the university. But I am clear about one thing: I learned what was news or, at least, the criteria to point out whether an event is news. When the issues that can be discussed are put on a wording, different aspects are valued. Truthfulness, current, proximity … and novelty. And if an event comes out in the media it is because it is usually “unique, unpublished, unlikely or out of the ordinary.” I don’t say it, University institutions say. That is why it makes little sense to affirm that electric cars are dangerous based exclusively on news. We could do it if we had relevant studies that pointed out that the number of electric cars is notoriously higher than those of combustion. But it is not the case. We do know that the fire of an electric car is more complicated to turn off and more virulent. That is why it is logical that take action on ships where they are transported or working on New protocols in fire bodies. That does not mean that the risks of this technology are greater. In spite of everything, it also enters within a certain logic that when a fire is given or any other risk situation, the alarm voices are multiplied. From municipalities where They consider whether to continue buying electric cars a parking lots that prohibit their step. In that case, companies only have to show that their batteries are as safe as any other component of a car. As if I could pass them a tank over them. The crazy idea of ​​a tank Although it seems nonsense, it makes sense that manufacturers refine ideas when demonstrating the safety of electric car batteries. Keep in mind that, for example, In South Korea, an intense debate has been lived on whether or not these cars may accumulate in garages after A Mercedes Eqe will explode last year. When Byd arrived in Spain he had a challenge ahead. I needed to make themselves known and, above all, demonstrate that it was a company in which you could trust. We already know the prejudices towards the Chinese product. As a journalist, I don’t know how many times I could visualize This video in which a nail is going through an LFP battery without anything happening. It was one of the classic images. The other was the pressure tests. When too much pressure is applied to a battery (electric car or any other device) runs the risk of experimenting A thermal leak. Heat grows inside, chemistry is released and the pressure increases to cause an explosion with the consequent fire. To avoid this, the housings are designed to release the accumulated pressure inside, with the aim that if we have an accident, the pressure exerted on the battery does not cause an explosion. And the company can already tell us about figures and data and everything we want. But nothing better than the visual. Click on the image to go to the original tweet That is why Geely, explain in Carnewschina He has taken his new “Aegis Gold Brick Battery” a 36 -ton tank and has passed it over. And what happened? Nothing. Nothing at all. The battery did not give any sign of damage despite receiving 1.8 times the minimum pressure required by Chinese institutions to standardize a new battery. You can see the video on this link. They point out that the tank not only He crushed the battery On one occasion. He passed over it, returned on his steps and continued to crush her repeatedly. And did the same going over individual cells. The battery package “maintained its structural integrity without bulges, leaks, fires or explosions,” they emphasize. To overcome the test, the aegis Gold Brick Battery has been designed with a double wet coating that facilitates the dispersion of heat and thermal leaks since it is especially heat resistant to heat generated by aluminum oxide. It also has liquid-electrical separation of the materials. Photo | Geely In Xataka | Samsung has just revolutionized batteries for electric cars. In autonomy, in load time and in useful life

The Artikutza reservoir in Navarra has remained empty despite the rains. His destiny is another: the demolition

by

The rains of recent months have caused many of the reservoirs of the Peninsula to go from practically dry due to drought to recover flows more typical of normality. That is not the case of the Artikutza reservoir, a Navarrese reservoir located near the border between the Foral Community and Gipuzkoa. The reason is that the Artikutza reservoir is a dead reservoir, and its prey, as we know it, has the days counted. Green light to demolition (partial). The San Sebastián City Council It is prepared For the partial demolition of the Artikutza dam as reported by local authorities. The infrastructure, in disuse for more than 20 years will be measured so that the so -called Enobieta regatta, whose flow retained the prey leads to the Añarbe River without having to cross the infrastructure pipes. The works are expected to begin in 2026. Wasn’t we in Navarra? According to He tells Iñigo GarcíaCouncilor for the Environment of the Donostiarra Consistory, to Efeverdethe history of the Artikutza reservoir begins in 1919, when the City Council bought some land next to the population of Artikutza, in the north of Navarra in order to build a reservoir that supplied water to the coastal municipality. The dam never was fully filled: in 1948, geological problems were detected that limited the filling capacity of the reservoir to approximately half of the planned volume. In spite of this, the reservoir was the main source of water supply of the Guipuzcoan capital between 1960 and 1976, when downstream entered into the service of the Añarbe reservoir, of a much higher volume to face the population growth of the city. A spoiled dam. In 1992 the reservoir stopped supplying water to the municipality of Donostia, but its final decline would begin ten years later, in 2002. This year, a failure in the electrical maneuver Reservoir coffin. Reservoir that would end emptying more than a decade laterbetween 2017 and 2019. A duct in the lower part of the dam allows the small regato to flow with hardly any restrictions, but the new project seeks to further facilitate the transit of the river and avoid risks derived from the accumulation of sediments. A partial demolition. We indicated at the beginning that the demolition of the dam would be partial and not total. The Donostiarra Consistory considered three demolition options: the total demolition, the partial and the possibility of maintaining the current channeling to maintain an open passage. Finally, the decision was favorable to the partial demolition, which implies the opening of the dam through a vertical cleft of seven meters wide below one of the old reliefs of the dam. This would allow recovering the natural flow of the river avoiding at the same time A cumbersome work in a protected natural environment and complex access. Protect fauna. Now the question fits, and all this for what? The possibility of leaving things as they were was on the table. However, it was considered that the opening of the dam was an ideal way of guaranteeing biological connectivity without the risk that the accumulation of sediments will hinder the passage of water and animals. There are several species whose conservation has been influenced when explaining the ecological impact of the project. The first is The Iberian Desman (Pyrenaicus Galemys)an animal that also receives the nickname of the “Spanish ornitorrinco”. This animal is one of the most threatened mammal species of our environment and has a small population in this hydrographic basin. The authorities also highlight the existence of “Bat populations of much biological interest” that inhabit the interior of the dam.

We have genetically edited a spider to produce a fluorescent red cloth. And the implications are promising

by

Mutant spiders. It could be the premise of a film that mixes science fiction and terror, or someone’s nightmare with Arachnophobia. However, the first mutant spiders created by the human being respond to something much more innocent. But maybe even more interesting. Mutant spiders. A group of researchers He has genetically edited A group of spiders. The most curious of the results obtained by this team is probably a group of spiders that, after the edition, are capable of weaving a red spider web fluorescent spider. It is about First experiment of genetic edition in spiders of which we have knowledge. For this, the team resorted to specimens of the American domestic spider (PARASTIDA TEPIDARIORUM), A species that, like many others, uses its spider web not only for hunting but also to protect its eggs. A fascinating material. Spider silk is one of the most interesting materials in the animal world. Spiders are capable of segregating different types of fabric and among them, structural silks are among the most remarkable for their very tangled resistance that binds to its elasticity, lightness and the fact that it is a biodegradable material, explains the team responsible for the study. CRISPR-CAS9. In its experiment, the team turned to the “scissors” of genetic edition CRISPR-CAS9. They began the process focusing on a gene linked to the development of the eyes with the aim of obtaining a first easy result to identify. The team injected his tool of genetic edition in a female in order to eliminate the gene chosen in their reproductive cells and thus be able to detect changes in their litter. The Resutlanted: Spiders who did not develop their eyes. From the eyes to the silk. The first success led to repeat the test, but this time focusing on the genes responsible for coding some of the proteins present in the structural silk of the spiders. In doing so, spiders wove spider silk filaments of fluorescent red spider. The details of the experiment were published In an article In the magazine ANGEWANDTE CHEMIE. A first step. To be able to edit the genes responsible for the production of a material as interesting as the structural filaments of spider fabrics opens new doors when it comes to knowing this material and its biochemical origins. Of course, we can also pave the way for being able to synthesize it efficiently or even in the development of materials with similar properties. “We have demonstrated, for the first time in the world, that (the tool) CRISPR-CAS9 can be used” to incorporate a desired sequence in spider silk proteins, thus allowing the functionalization of these silk fibers, ” stood out in a press release Thomas Scheibel, co -author of the study. “The ability to apply CRISPR genetic edition to spider silk is very promising for material science; for example, it can be used to increase the already high spider silk breakage.” In Xataka | ‘The Last of Us’ is already happening in the animal world and the last species in suffering are the “spiders of the caverns” Image | Patrick Edwin Moran / University of Bayreuth

Four AI companies control how Half Mundo reasons. It is the greatest concentration of intellectual power in history

by

While the public focus is concentrated in the possibility that the AI ​​will take our job ahead (Business Insider 21% of its template has just announced citing it as a cause, the CEO of Axios has published A text by the chungosAnthropic’s CEO has shouted “that comes the wolf” to justify that only they can save us), In the background something less visible is happening: We are giving our intellectual autonomy in favor of efficiency and comfort. It is not just that four companies –Openai, Google, Anthropic, Meta – are building the infrastructure with which millions of people resolve doubts and make decisions. They not only manage data: they also protect the way we link ideas. The Great Chinese of AI They are out of this equation for a simple reason: their still domestic approach without the international vocation of the Americans. Google (the search engine) was and is influential, but with it we have had to spin our own speech: Cotejar Fuentes, Weighing biases, assume contradictions. The generative AI instead serves a round response that It sounds coherent even when hallucin And that’s why he demands less surveillance. The result is that we are replacing the “internal process” with an external verdict covered with a technological aura that deter the replica. Whatever you say, Chatty. Delegate is too tempting. Save time and headaches. The problem is that we do not subcontract logistics, but criteria. We ask Chatgpt A professional strategy. TO Claude A curriculum. TO Gemini today’s interpretations. In doing so we accept without discussing the biases and empty of a trained model about texts that we will never see. It is an invisible assignment and, therefore, difficult to question. Never before so few hands had defined what questions can be asked and what answers sound reasonable. History has known infrastructure monopolies – electrity, internet, railways – but never one about reasoning patterns. Now another qualitatively appears: It operates on the symbolic plane, where narrative frames are defined through which we understand the world. Very subtle and very decisive. What previously implied a deliberation – read, contrast, imagine scenarios, weigh nuances – today becomes an instantaneous response, of definitive appearance. What to think about euthanasia? How to react to infidelity? What economic model is more fair? We no longer look for elements to think: we look for the correct answer The faster and more comfortable. And we accept as valid the one that sounds best, even if it ignores what does not fit in your narrative. Its effects will not be immediate, but predictable: a slow loss of variety in thought, of ideas out of the ordinary. Platforms have progressive consequences. Tiktok and Spotify, for example, They have made the songs last less and the chorus arrive before. What consequences will the LLMS within fifteen years? If we all consult models that converge towards average responses, intellectual eccentricity – culture rate for innovation – It will be increasingly weird. There is hardly a brake for AI, but perhaps at some point we have to decide how much reasoning we are willing to deliver before staying without it.

There are those who are adding fungi such as cordyceps to coffee to lose weight. Science has many reservations

by

Coffee is a food, with numerous positive effects on our body. We get more and more about this Positive coffee actionbut we have determined to improve it adding supplements as proteins either Spirulina. One of the latest trends? Enrich coffee with fungi. So that? To lose weight. And here the evidence is not so clear that this trend of ‘Mushroom Coffee’ is so healthy that invites a coffee with cordyceps to drink. The promise. Eating mushrooms or fungi has nothing weird, but a few years ago we began to see how the food industry It began to add them to other foods to create improved versions of them. One of the first brands that added fungi to the cocoa or coffee was FOUR SIGMICan American company that creates “functional foods” and well -being supplements. That is, coffee is not only coffee: it has a series of additions vegetables to relieve these, support the immune system or accelerate weight loss. The latter is what a more recent grabs Trend in networks like Tiktokthe baptized as ‘Mushroom Coffee’. There are several brands that sell coffee with fungi Cordyceps coffee. The defenders claim that coffee (and other foods) can be enhanced with medicinal fungi whose compounds carry a series of positive effects. Among those fungi are Reishithe León hairhe Maitake or the Shiitake (great in broths)but also the most famous cordyceps. Yes, that parasitic fungus that makes Some ants become ‘zombies‘And what is protagonist of the Apocalypse of ‘The Last of Us’. These fungi can increase energy production and improve metabolic function, helping in the burning of fats. They can also help control hunger, stabilize glucose levels and have Probiotic properties that favor both digestion and nutrient absorption. Market. And it is not a bizarre or the US thing: you can Buy coffee With cordyceps In Amazon If you want the healthy effects of coffee more, Chow they announcegreater energy and improvement in your mental clarity. There are different estimates, but this coffee market is expected to grow at a rate of between 5.4% and 5.7% during the next decade. There are studies that place their value at 1,203.4 million dollars in 2023 with a growth up to 1,833.4 million by 2031. They are considerable figures, but we compare, the estimate of specialty coffee is 62,500 million by 2032 and that of the entire market It will be of 632,000 million for that year. But well, it seems that this trend, little by little, is consolidated and grows. The small print. The logic here seems simple. In the case of protein: if it is a good supplement and coffee is a good food, mixing them works. With fungi and coffee the same thing happens, but something that should not be overlooked: there is a lack of research. The relationship between coffee and weight loss is well documented, being a good stimulating before performing some training and selling the caffeine as supplement. But, although the properties of these fungi are also documented, evidence on coffee with fungi and its action in weight loss or mental well -being is limited. Clinical trials are missing that confirm its direct effectiveness to lose weight and most of those available studies are in animals. Also, as we read in VogueNutritionist Marta Marcè comments that it is not usually specified whether the extract is from the fruiting body (rich in properties) or the roots (less powerful), in addition to using very low doses. And sometimes It is not even the real fungus. Dangers. Although cordyceps has a bad reputation due to fiction products in which it has been the protagonist and its effect on some insectsusually has no health hazards. Cordyceps coffee is approved by the USDA -The United States Department of Agriculture-, but you have to take some things into account. It may produce some allergies in certain people and it is necessary Influence when combining it With other stimulating products or drugs, but most importantly, above all, it is to know where those fungi that supplement chocolate or cocoa. Marketing, already such Because here the danger is how that fungus has been manipulated and the example we have had in Colombia, where a health alert on cordyceps supplements not regulated or fraudulent. And if you dare to try it, be from reliable and out of curiosity, not so much for its numerous promises, that millions move in the other part of the world.
