Renault and Geely have an engine to convince the undecided of the electric car. The secret is that it is combustion

by

We are on the way to a future in which the electric car He has ballots to become the winning option. There are countries that They are already betting Very strong for the electric ones, so much that they are even unseating combustion. But, for many others, the conventional car It is still the best option. And it is for autonomy, for the ease of reposting and because there are places with underdeveloped load networks. This is something that Chinese manufacturers themselves, who bet so much on the electric ones, have assumed. In fact, Cherywhich is the company that owns omoda and Jaecoo, is finalizing the Landing of its combustion cars in Spain. But, of course, companies do not forget that electrified future and want to create a bridge between combustion and 100% electric for the user to jump safely. And what is that bridge? A combustion engine to “hybridize” the electric ones for which Renault and Geely are betting hard. The combustion engine to convince the ‘haters’ of the electric Here we must talk about Horse PowerTrain. This is a company whose 45% belongs to the French Renault, another 45% to Geely and 10% to Aramco. It is a call Joint Venture To boost New systems automotive, especially electrified due to Geely’s experience. And the truth is that his approach is … curious. And it is because they have been looking for an engine capable of giving life to the calls “extended electric cars “. Also known as E-Rev (Extended Range Electric Vehicle), these cars have one or more electric motors that feed on a battery. So far, they are a conventional electric, okay, but special thing is that they have an additional engine: combustion. Each manufacturer has its system, but it is basically a car that behaves like an electric, but When the battery reaches a certain level, the combustion engine is turned on And it is not the one that moves the wheels, but the one that generates electricity, feeds the battery and allows electric motors to have energy to continue driving the wheels. The difference with a conventional hybrid is that this combustion engine is never the one that drives the car, and the great advantage is that this fuel engine is like a huge battery that allows autonomies that, until the arrival of the solid state batteriesthey seem complicated for 100%electric. Reviewed the theory, let’s hort. A few weeks ago we told you that the company will try one of these engines, The promising Spanish engine e-rexbut we also see that they will not put all the eggs in the same basket. In the Shanghai Motor Show that is celebrated this week (in which my partner Javier Lacort is), And how we read in Bloombergthe general director of Horse has commented that they have prepared an engine that can “integrate without problems into the construction platforms of electric vehicles with battery.” Matias Giannini, in addition, has commented that “the concept will allow car manufacturers to offer diversity in propulsion systems, with minimal alteration in its production process and in the use of resources.” Thus, if a brand has 100% electric, but wants a hybrid, I would not have to develop a new platform To include a large conventional engine, but to alter minimally the one that has already available for your electric only to introduce that small additional combustion engine. And they don’t have one, but two: Gemini – A 1.0 -liter generator, 2 cylinders and a very compact power that works with mixtures of methanol and gasoline. Another 1.0 liters, 3 cylinders and a power of 86 kW compatible with flexible fuels and an integrated electric generator. This, by the way, is manufactured at the Curibita facilities in Brazil and Valladolid in Spain. In the first statement, Giannini commented that these engines will be on the street at some point in 2028, and it is only a matter of time to see what arrives before: if the solid state batteriesthe consolidation of the E-REV (BMW, Nixssan or Mazda They already have some models) or if by 2028 everything will continue as until now. Or, simply, the future of the electric may not be as binary as we think, but this intermediate hybridization.

Who produced the key matters of the world after World War I, in a 1927 graphics

by

The end of the Great War He left a totally devastated Europe. France, Italy, the United Kingdom and Germany lost between 25% and 30% of their national wealth and basic agricultural and industrial infrastructure was very damaged. After a first period of recovery just after the end of the war, there was a situation of hyperinflation, monetary depreciation, debt payments to an US that claimed his money and a break in international trade. However, in mid -1920, an economic recovery was lived, and a series of graphics published in 1927 reflects that moment of fleeting splendor just before the Great Depression and of the Second World War. And why not say it, they were a valuable tool if someone with expansionist ideas He threw the glove. Happy twenty years. After the World War IUSA lent money to France and the United Kingdom to rebuild. Germany was punished He pays a rate to those same countries, but when the US claimed the money, the system broke. Germany had no money and France and the United Kingdom needed German funds to pay Americans. However, the Dawes Plan To give a respite to the German economy, so everyone’s debt relaxed and began the “happy twenties.” It was an economic recovery period in which the countries involved reached some stability and, above all, an industrial rebirth. It continued depending on American money and we already know how the decade ended with the breakage of the stock market, but at least allowed European nations to be repurchased in a way. Hickmann Atlas. No levels prior to the Great War were reached, but at least the production and export of raw materials resumed. Beyond Europe, there were many other countries that had been oblivious to the conflict and followed their own path. In 1927, the Austrian publishing house G. Freytag & Berndt published the universal geographical and statistical Atlas of Hickmann. It is a very interesting document because it reflects that panorama of the mid -20s and offers many, many statistics, graphs and maps that are a reflection of the economic and productive state worldwide. We can consult the 80 pages on the web David Rumsey Map Collectionbut from Visual Capitalist They have compiled the most interesting maps in terms of production and raw materials. Land use. The pages dedicated to ‘Produktion’ show precisely that: the most powerful countries in certain types of interesting resources at the time. The first cover the use of the Earth and the graph is divided into: Acherland: Cultivation lands or farmland. Wald: forest. Wieen und Weiden: Praderas and grasslands. Unproduktivland: unproductive land. There are countries like Spain that are very balanced, with large cultivation surfaces and practically identical proportions of the rest, but also striking cases. For example, according to this Atlas, France is the country that, with 56%, more arable land has. They captured that Finland had the largest amount of forests, covering 61% of their territory (in 2021 estimated That was more than 73% and British India was the one that had the most won, followed by the US. And the worst? Norway, with 70% unproductive land. Agricultural production. In Produktion III and IV they focused on land production, and for the Austrians, the US was an agricultural power plant. They were the ones that most wheat, barley, oatmeal and corn produced (by far). The Soviet Union led in Centeno and Germany, obvious, in potato production. Argentina was the second in production of corn and Spain the third in barley. Who had less grain, mattered. Whose? From Argentina, Canada, the United States and Australia, and the great importing countries were the United Kingdom, Germany and Italy. As for wine, France was the spearhead, followed by Italy and Spain. In beer, the United Kingdom marked the pattern, followed by Germany. In that graph, Spain does not appear. In other resources such as Café, Brazil is a lot of difference from Colombia, El Salvador, Venezuela or Guatemala. And China also makes an appearance as a power in the production of tea and rice. Textiles and natural resources. As for textiles, it depends a lot on it. The United States led cotton production, followed by the British and China Indies. Japan and China were silk powers; The Soviet Union and the Philippines were of the hemp culture; The USSR and Poland led the linen, and the hops was a thing of Great Britain and the United States. The oil is a barbarity and, perhaps, the fact that puts us most into perspective with what they thought a century ago. In the Atlas, they indicate that the United States produced about 753,000 barrels in 1923. One hundred years later, US production was 21.4 million barrels … a day during the last quarter of 2023. In tobacco, salt, oil, rubber or paper, Spain has little to say, but where it stands out is in Mercury, very close to Italy and a lot of distance from the United States or Mexico. Mining. Produktion VII and VIII reflects the production of metals, gems and minerals, with South Africa leading the production of gold and diamonds and Mexico that of silver. The United Kingdom had the leadership of gas, but the absolute protagonist in the Serurgy after World War I, and something that would be key to the second, was the United States, leading coal, iron and steel. Cataclysm. The photo for some countries was really hopeful, but only two years after the publication of Hickmann Atlas produced The collapse of the NYSE. This caused the bankruptcy of banks, a reduction in production, protectionist measures and a break in international trade. The US was no longer to lend money to anyone, which caused a worldwide deflation. Europe, which was already indebted to the eyebrows, also suffered this recession, devaluing its coins and causing a new crisis. If a new volume of Hickmann’s work had been published years after the great depression, the situation of the graphics would have been very different. There were some visual … Read more

is to use AI as an oracle instead of as a tool

by

A century ago, being illiterate was not knowing how to read or write. In developed countries That problem today is residual. But another type of illiteracy is emerging. More subtle, more difficult to detect, with more gray and perhaps equally determining: Not knowing how to interact with AI. This new literacy does not know how to program or understand how models work. It is something more basic: know how to ask good questions, know how to read the answers, and above all, know how to distrust. Not in a paranoid way, but with criteria. Distinguish when we are using AI … and when AI is using us. It is the difference between being a passive AI user – some who swallows without chewing – and using it as a lever for thought, as an extension of our analysis capacity. Because, well used, it can be that: a cognitive multiplier. There you play A huge difference: There are those who use these systems as if they were a vitaminated google or a estroid calculator. He throws a question, copy the answer and voila. Other people – even more – are learning to talk with them. To stretch its limits. To generate ideas that neither the machine alone nor them could have produced. The key is not the tool, it is how you use it. And for that it is necessary literacy in AI. The thing goes beyond who does what with Chatgpt. Systems like Deep Research They are beginning to automate tasks that, until recently, were the point of entry to many professions. Reports, summaries, preliminary analysis … just that type of work that served to train, to understand the trade from within. If you give that to a model, how do you learn to think like an expert? That is The black hole that is coming in many companies. If you automate the formative tasks, how are you going to train the new ones? If we do not redesign well – and fast – how the experience is transmitted, we could have entire generations without a real basis. People with titles but without criteria. And not only that: this new illiteracy can be hereditary. Like parents who did not read they did not raise reading children, those who do not know how to use these tools will hardly teach to use them. Learning will remain in the hands of school … or algorithm. The paradoxical is that All this disguises himself very well. Someone can generate a brilliant report, a perfect presentation, a seemingly solid analysis … without deep understanding, much less. It is enough that you know how to ask for it well. The risk is not just that mediocrity is imposed. Is that nobody realizes. As Antonio Ortiz has been notifyingthe real problem is not that AI thinks for us. It is that, little by little, we stop thinking about ourselves and our atrophy begins. That is why the true digital literacy of the future will not be technical. It will be ethical, critical, cognitive. Know when to ask the AI ​​to think about you. And, above all, when to say no.

The US deserts have 1,200 GW solar for AI. The only problem is that Big Tech do not dare to use them

by

The Data centers They are the new 21st century factories. And like any factory, they need energy. A lot of energy. The main technology companies are building and operating Great data centers that allow offering services (video or Streaming video gamesfor example), but also where the different models of artificial intelligence. The problem is that They need more and morewhich translates into a growing energy demand. And although there are those who bet on the nuclear power and for the reactivation of fossil fuels, a study considers that the future is in the Solar energy outside the energy network. The problem is that, although the solution sounds great, it is not being applied. Hyperscalists. This is an important term. Technology companies that operate cloud computing infrastructures on a global scale are known as ‘hyperscalist’. Its data centers are crucial for the development of digital services, but also for the ‘big data’ and the advance of AI, and the term “hyperscalist” responds to those data centers can be scalar quickly and on demand. Climbing … how? Well, depending on the needs of that company and the fan that wants to cover, that scalability translates into more storage, a faster processing or a greater bandwidth on the network. Demand. The main players in this are Google, Microsoft, Meta or Amazon and although they have the capacity to expand their data centers, they are running with a huge problem: the amount of resources they consume. In large server centers, Water consumption It has always been a problem that companies have solved in different ways to be more responsible with the environmentbut the arrival of AI has been a revolution. Train and maintain these models consume a A large amount of energy resources And, apart from the water to dissipate the heat of the servers, a great energy capacity is needed. So much so, although there are companies Building more sustainable data centers At the structural level, energy demand is so brutal that They require coal and natural gas To meet demand. And some like Google either Goal they will use nuclear energy to feed your needs Energy out of the network. Contextualized the problem and seeing that these energy needs play against decarbonizationinvestigators of companies such as Stripe, Paces or Scale Microgrids have got to work to determine the best solution to feed those data centers in a sustainable way. His conclusion has been presented in a study in which they estimate that the total energy demand of the AI ​​for 2030 will range between 30 and 300 GW. In the case of the centers where AI training is carried out, that demand will be between 15 and 150 GW. It is a huge fan, but the solution they pose and that they consider optimal is the creation of micro -redes outside the network, fed by solar energy. According to them, systems with 44% solar energy are already competitive in costs compared to those based only on gas, and those that reach 90% renewable can be even more profitable than nuclear projects such as Three Mile Island of Microsoft. Green spots are green plots for a 90/10 stage Build where the sun glued. The advantage of this system is that its construction is fast because you do not have to reactivate a nuclear power plant. You are not tied to what the energy market demands, Geopolitical conflicts They do not leave you without supply, it is clean energy, buy solar panels is getting cheaper And, above all, it is easily scalable. If more energy is needed, it is as simple as adding more panels, but the most important thing in this equation is that they can build these centers in optimal places. Unlike servers centers, which do need to be close to the end user to offer a better service, the data centers in which the AI ​​training is carried out have geographical flexibility. This implies that they can install them in areas with optimal solar radiation and in places where the land is cheap. Optimal areas Optimal areas. In the study they have identified plots in the United States with a potential for up to 1,200 GW of solar energy outside the network, with gas support and an optimal area with large esplanades and radiation during a large percentage of the year. So, CaliforniaNevada, Arizona, New Mexico and the east of Texas They would be ideal places to house those data fueled data centers outside the network by 90%, with the remaining 10% backed by gas. Beyond this, the study points out that most of the appropriate land is private, so it can be purchased to build these facilities and that, in addition, many are within lands that would allow subsidies. If you start today, the construction bond would be between 12 and 24 months and everything seems positive, but it is not being done. If it is so good … why isn’t it? According to researchers, there are three issues that come into play. Two are closely related and have to do that this of AI training is a very recent phenomenon. The designers of the data centers have historically been skeptical when it comes to getting off the network because what they wanted was to enhance, above all, the reliability. They can’t stay a second without energy, go. Related to the historical tendency is inertia: it has never been done before, although current technology would allow to operate only with renewables (as some countries already do). And the third reason is the cost, $ 23 per MWh, specifically. The panels are increasingly affordablebut it is more expensive than not buying those panels -evidently. However, the researchers point out that this extra cost would be dampened by the Cost of emissions and compensation that would be avoided in the short term. Therefore, these solar micro -lands outside the network seem a quick way to feed large -scale data centers, but although technology is mature, it seems to spend time until … Read more

A crossover with sharp lines, high connectivity and a clear nod to the new generations

by

The immediate future of omoda goes through radical forms. In Wuhu, China, the Chery group brand has revealed The new omoda 3, a crossover compact that adds to your global offensive. It will arrive from October 2025. We have been there to know it in person: a model that, even without a confirmed price for Spain, could be placed in a fork between 23,000 and 27,000 euros – although this is, for the moment, pure speculation. Omoda 3 technical sheet Omoda 3 Body type Five seat SUV-B Measures and weight Not specified (about 4.4 meters long) TRUNK not specified Maximum power not specified WLTP consumption not specified Environmental Distinctive Not specified, but there will be electrical and plug -in versions, so “0 emissions” is expected Driving aids (ADAS) Mandatory Adas Aid by the European Union. OTHERS Own software compatible with Android Auto and Apple Carplay. Compatible with Nintendo Switch. Interior design inspired by a spacecraft. Electric hybrid Yes, planned (there will also be 100% electric and combustion versions) Plug -in hybrid Yes, planned electric Yes, planned price and launch To confirm, as of October 2025 (global launch) A lot of information has not yet been revealed, we understand that for the remaining months until its commercialization and for the possible regional variants that are to be defined. Design that everyone does not seek to like, but to make a difference Image: omoda. With about 4.4 meters long (exact figure to be confirmed but places it in segment C, although the first impression is b), omoda 3 is strategically located below the Omoda 5and share with him the Modular T1x platform. However, its stylistic proposal is not limited to a simple lower step: it is a declaration of intent. Sharp lines, a front that reminds more of a Concept Car than a production SUVand a treatment of optics – stakes, torn, aggressive – that seeks to leave visual mark. Image: omoda. The comparison that many made in the run around him is not accidental: his grill and design language evoke models of much higher rank such as the ELECTRE LOTUS or even the Lamborghini Urus. A risky bet, yes, but consistent at the same time, because omoda 3 does not want to like everyone. He wants to seduce those looking for something different in a saturated market of clones. Its interior, baptized as “Starship Cockpit”, follows the same futuristic philosophy. In the center, a large format vertical screen acts as a connectivity center: compatible with Nintendo Switchwith inspiration graphics SCI-FI and configurable atmosphere, including even a “spaceship” sound mode. Of course, we couldn’t see it live, only in the video: the model was cordoned off. Angular, provocative, generational Image: omoda. In the most equipped versions, the details reach an unusual theater in their category: The boot button is hidden under a red -style red lidit has environmental in abundance and seats, cutting Gaming, They have been baptized as “Starship Commander.” Everything wants to be space here. Modularity will be another asset. Although omoda still is silent on the engines, we know that 3 will have 100% electric versions, plug -in hybrids and traditional combustion. Flexibility is total, but the emphasis will be in technological experience, radical design and a customization package that we had not yet seen in omoda: “Racing Packs”, official vinyl and a range of accessories Customize each unit. Beyond its aggressive design and futuristic winks, omoda 3 also wants to be an emotional extension of those who drive it. The brand does not speak only of benefits or style, but – continuously – to build a genuine connection with a generation that not only buys cars, but also identity symbols. In that aspiration, omoda 3 is not sold as a vehicle: it is presented as a kind of vital ally, a piece of a lifestyle that transcends displacement. Indeed: ways of living. The movement is not improvised. Chery knows that, To compete outside China, it is not enough to offer a price. You have to conquer imaginary. And omoda 3, with its video game aesthetics and its promise of differentiation, is launched just for that generation for which to conduct is also a statement of identity. It will not be a car for everyone. But neither does it pretend. And in that – in a world of increasingly interchangeable products – it may be precisely its great opportunity. Of course, you will have to see the price that hangs from your label.

Vietnam has tired of China’s artificial islands, so he has decided to start building his own

by

China has been pulling tons of sand for more than a decade. And not only is he doing it for Build airports: They are dozens of artificial islands for expand its military power. It is about China’s strategy to claim the maritime territories that they consider their own and that are also doing in the Yellow Sea coast in front of South Korea. The problem is that one of its neighbors has been tired. Vietnam has also begun to lift artificial islands in the same territory with a clear objective: to prevent China from conquering the area. AND The tension is servedclear. Spratly Islands. It may seem more reef, but that of Spratly Islands It is tremendously important at the geopolitical level. It is a reef that is located between four countries whose relations, in some cases, are a hotbed: China, Vietnam, the Philippines and Taiwan, and they are also a set of rich islands in resources natural as fishing banks (suitable for a China to which His folders fall short), oil and natural gas. It is estimated that there are 105,000 million barrels of oil and many other millions of gas drums. There is tension, therefore, to control those resources, but also because it is a relevant point at the strategic level. They are located on one of the most busy maritime routes and are key to both international trade as for world movement. Controlling that archipelago implies having an essential influence globally. Claims. And the situation is a chicken coop. The archipelago is composed of a hundred islands and there are countries that carry decades claiming his sovereignty over it. On the one hand, China says that the fishermen of the Ming dynasty of the fifteenth century have already established themselves there, so the islands belong to them. In addition, in 1947 they made a map that showed how they all belonged to them, starting to occupy some of them in 1988. Malaysia se put In the fight in 1979, claiming part of the archipelago, the same case as Brunéi. Philippines is another player on this board, occupying some islands and occupying some of them with soldiers, but the most persistent are Taiwan and Vietnam. Both demand the entire territory as their own. Taiwan, with the same foundation as China, and Vietnam, stating that the islands were part of the kingdom of Annam – predecessor of the country – during the nineteenth century. Both China and Vietnam recovered archaeological remains to demonstrate that the islands belonged to them in the past and had to remain their property today. But since they did not convince each other, they decided to go to action. Mischief is an example. It is in Chinese power and has names in different languages ​​depending on which country you ask. For China is měijì jiāo. For Vietnam is đá Vành KhĂn. And for the Philippines is Bahura Ng Panganiban. Everyone considers that it is yours Background. Thus, and at some point in 2013, China began to move. Taking advantage of the rocky parts of the reef close to the surface and using Dredging ships to lift the bottom of the sea, they began to build islands and extend some existing ones. In just five years, they created seven artificial islands, the transformation of atolls into comparative satellite images being evident. Militarizing the archipelago. In this whole story, the military presence of the countries involved in the conflict has been key, starring even armed incidents between them. And one of China’s clear objectives is the militarization of this space with a double objective. On the one hand, the most obvious: if you create an island and the militarizas, you make sure that if someone wants it, you also have to arrive with armed troops, being able to trigger a greater conflict. Subi is one of the islands in which China has placed an airport. So it was before and after 2016 On the other, establishing and reinforcing the military presence in an area that, as we say, is key. It is something we have seen recently, with the discovery of A radar anti -furtive ships on one of the islands. And it is a radar, yes, but also a powerful message in an area where the United States also has the eye: if the US and its allies cannot operate poachers in the South China Sea, they may not be able to deal with the forces of the popular liberation army. Discovery Great Reef is held by Vietnam and down to the right we see some changes. Philippines, Taiwan and China say it’s them But well, it is not just a radar: there is also a missile launch platform, and in several of the islands occupied, created or expanded by China we can see presence of military infrastructure such as bases or airports. In this TWSJ video we can see perfectly the evolution of the islands: Vietnam is planted. In 2021, Vietnam got tired of the situation and, being together with Taiwan the country that has the most interest in the archipelago, also began to lift islands in the Spratly. Mainly, for military and port presence that reinforce maritime logistics, but putting the direct in recent months. Since June 2024, Vietnam has “grown” 641 new hectares and measurements Totals of expansion 1,343 hectares compared to 1,882 of China. And the expansion is being rapid: in 2021, Vietnam only had four advanced ports with port. Now, it has tripled that number with cases such as Barque Canada Reef in which only the atolon was intuited and now has even a landing floor. Before and after in the reef Barque Canada Complaints from each other. The objective of one and others is to operate more time and in greater numbers on those islands before a relief arrives, being able to carry out maneuvers and patrols during the area throughout the year, but curiously, although Vietnam had already shouted in the sky before with China’s movements, it is … Read more

We have been looking for the definitive cure of allergies for years and we have not yet solved the big problem: understand them

by

The end of the rains and the arrival of good weather have, for many, a dark back: The allergies. Spring, and especially the months of May and June, brings us the pollen proliferationone of the most important allergens, the main cause of sneezing at this time of year. The most common way of treating this type of allergies is through antihistaminesdrugs aimed at blocking the effects of histaminea neurotransmitter that also plays an important role in immune system. Recall that allergies are nothing other than a reaction of our immune system to external substances that understands as dangerous and that are not really, allergens. Antihistamines are very useful when treating allergic symptoms. But one thing is that, and another thing is to definitively cure these disorders. Today we do not have A cure for allergiesbut at least there are some routes open to hope. So close we are to achieve it. Perhaps one of the first treatments that come to mind when talking about healing the allergy are vaccines. What we understand today as vaccines against allergy are immunotherapy -based injections, and its logic is not far from conventional vaccines: it is about administering a small amount of what causes us allergy capable of alerting the immune system without unleashing an allergic reaction. While they are a useful treatment in many cases, they do not finish solving the problem, so we will need periodic injections that will improve the response capacity of our immune system. What ways are there open? Almost ten years ago, We commented on some of the open research lines in the search for a cure for allergies. These ways included, for example, the “biological therapies.” These are therapies that focus on antibodiesthe proteins that our body produces when it detects substances that it understands as harmful. This type of treatments They are still One of our great hopes. An example of this is omalizumab, a drug in principle aimed at combating asthma and approved two decades ago in the United States. In recent years, science has been validating this therapeutua option. A recent example is in A study Posted in 2022 in the magazine Clinical and Translational Allergy. In this analysis, the team observed that the drug was effective when preventing spring allergic rhinitis. Understand the problem To understand how our knowledge has evolved in recent years, we must first understand why it is so difficult to find a definitive cure. The background problem is simple: We do not understand the allergies well enough to find a solution. We still do not understand why certain people suffer from a certain allergy while others suffer from another type of reaction, at the same time that others do not seem to have such problems. We don’t know either Why allergies are permanent despite the fact that the antibody that we generally associate with them does not usually remain in our body for long periods of time. Two studies Published last year in the magazine Translational Medicine Science They can help us understand this situation a little better, explaining at least this last point. The answer could be in an antibody that we usually do not associate with allergies, immunoglobulin G (IgG), and the cells that produce it. What the teams responsible for these studies discovered is that some cells responsible for producing IgG produce immunoglobulin E, which is associated with allergies, when they run into an allergen. The key to allergic “memory” could therefore be in these cells. Before going better, everything seems to indicate that the allergies problem will go worse. And is that every time More people suffer This type of disorders. There are several factors that could be, independently or together, behind rapid ascent in the number of allergic people in the world. One of these hypotheses is that of hygiene. Since our immune system is “trains” through exposure to external agents, the absence of these agents in early stages can imply that our system does not perceive them as normal and, exposed in later stages, ends up reacting disproportionately. s From the environmental point of view, we must also consider the presence of pollutants in the atmospherelike particular matter. These pollutants can also affect our airways, combining their effect with that of conventional allergens and aggravating the situation.

The “eternal chemicals” are already everywhere. And that includes one of our favorite places: Spanish wine

by

The “eternal chemicals” have become a hot issue. These chemicals are widely used in a variety of contexts but their increasingly common presence in the environment worries both environmentalists and the health sector. And for now we know little about the possible impact of these substances on the health of people and in ecosystems. “Eternal” chemicals in wine. A study by the environmental association European bread(PHASE Action Network Europe) He has warned of the presence in the European wine of one of the substances we usually refer to as “eternal chemicals”: trifluoroacetic acid. PFAS and TFA. PFAS are the acronym with which we often refer to the category of perfluoroalized and polyfluoralized substances. It is a family of synthetic molecules (there are about 4,700 compounds of this type) that stand out for resistance that imbues the union between fluorine and carbon atoms. These compounds They are useful For example, in the manufacture of non -stick objects, but they can also be found in pesticides, containers or hygiene products. This is a molecular union Extremely stabledoes not react to external agents so it is extremely difficult to make these substances decompose, either by natural processes or otherwise. That is why these substances tend to accumulate in nature and, potentially, in our body. Interestingly, one of the problems with these substances is in one of the products as a result of the decomposition of the PFAS, the trifluoroacetic acid (TFA). This is precisely the “eternal chemist” on which the new study has focused. 49 wines. The analysis It began with a dozen Austrian wines of relatively old vintages and was expanding to include more recent crops and other countries. In total, 49 wines were analyzed, including at least one produced in Spain. They observed that wines prior to 1988 They did not contain traces of TFAbut that from that year the concentrations were increasing, first little by little and, as of 2010, significantly. The average concentrations in the vines of vintages between 2021 and 2024 was 122 µg/l, although peaks of up to 300 µg/l were detected. Although the phenomenon extended throughout Europe, the team indicated that Austrian wines were the most affected. Other Detail highlighted By the association it was the correlation between the concentrations of TFA and waste of synthetic pesticides. Ecological production The study of European bread He noted that ecological production wines also did not get rid of the presence of these substances, although it is true that they showed some concentrations less than those found in other wines. To what extent are a risk? Today we do not know for sure the effects of “eternal chemicals” on our health, but there are some indications that allow us to get an idea of ​​these possible effects. TFA has been linked, for example, problems for Fertility; But other compounds of this family have also been related to immune problems and even a greater risk of cancer.

carry the battle of updates to the extreme

by

There is a new obsession by the main Android manufacturers: that of Offer how many years of support are possible. Until not too ago, most were conf formed with just two years of updatessomething simply unthinkable in the most current popular mobiles. In the last two years we have seen a magical number: The seven years of updates. A figure that, a priori, seems almost magical, and that raises life time (as long as the updates do not do more damage than well) exponentially. The problem? The same one we have been dragging since Android is Android. A clear obsession. Seven years of updates. Samsung was the first to open the ban, offering more support than Google itself. In response, the Google Pixel also had a seven -year supportboth system updates and security patches. It is a record for the operating system, propitiated largely due to the improvements in support that manufacturers such as Qualcomm. His latest processors allow up to eight years. The question is whether this makes sense. Birds in the air. Promise years and years of updates is fine. But there is only one manufacturer updating At a good pace: Google. Samsung has just announced the update to Android 15 for some of its high -end devices. The point here is that this version has been available since October. We have normalized that updating fast is updating half a year after Google present stable version, and another half of the next version of the operating system, Android 16. A loop that feeds the endemic evil of Android: the fragmentation. Seven percent. Only 7% of the devices worldwide are updated to Android 15. Or, in other words, 93% of Android devices are outdated. Fragmentation is inevitable in this operating system (With more than 70% global adoption), Given the vast diversity of devices in use. But 7% remain a very low fact of adoption. It doesn’t matter too much. A few years ago, updating the system version was to change design language almost in full every few years and access a remarkable number of news. From a time to this part, operating systems focus on stability and efficiency rather than offering draft news. The main change, AI, comes from the hand of models such as Gemini Nano, implementable without changing operating system version. Regarding the security of use, with being updated to the last patches and not having a too old version, it is more than enough. Manufacturers against. Android has moved away from the two years of updates and an acceptable minimum begins from four or five years. On breaking these barriers to approach the ten years of updates there are manufacturers with clear posture. Interviewing Daniel Desjarlais, product manager at Xiaomi, the response to why the brand offered no more support the response was clear: the average consumer’s life cycle is not seven years, it is three. Similar posture Share OnePluswhose posture about the mobile and the sandwich made talk. “Imagine that your phone is a sandwich. Some manufacturers are now saying that the filling of your sandwich, the software of your phone, will remain good to eat in seven years. But what they are not telling you is that the bread in the sandwich, the user’s experience, could be moldy after four years. Suddenly, a seven -year software update policy does not matter, because the rest of your experience is terrible.” Summarizing: manufacturers are at war with operating system updates. A war in which only Google is managing to fulfill deadlines, and in which it doubts how an Android will behave seven years later stalks the most skeptical manufacturers.

There was a time when we thought the birds migrated to the moon. Until an arrow released in Africa fell in Germany

by

Spring is a time that I always liked. Not for the Horrible processionarybut for the return of the swallows And, above all, of the storks. After a long winter, They return home to nest. Imagine the surprise if, one day, one of those stork appears in your locality with the neck crossed by an 8 -centimeter arrow. Stop imagining because that happened in 1822 in a German city. And far from being an anecdote, it became a key event to unravel the mystery of why birds They disappeared in winter. The doubt. Now it is no mystery and it is something that we learn at school since childhood, but not so many centuries, people did not know why, good at first, the birds were in autumn and reappeared in spring. Those Migratory processes in which even the smallest of the birds rEcorren thousands of kilometers without stopping They were not understood, which forced the thinkers of the time to launch hypotheses and theories that, in the absence of evidence, since they were accepted without further ado. One of the answers was evident. And it could be none than … Alien birds. That is what thought Charles Morton, a Harvard academic who, in the seventeenth century, suggested that the reason why some birds disappeared in winter was because they migrated … to the moon. Most likely you have raised your eyebrow thinking something like “impossible, they could not be so illusory”, but you have to put into the skin of someone who had no way to check the phenomenon and it was still an answer to a real mystery. Because what they knew was that they disappeared for months, but not the place they were going to. And as they saw the moon from Massachusetts, but not Colombia, because the answer was clear. But don’t believe it was the only crazy theory of the time. Aristotle, already in the IV AC theorized about the possibility of being transformed into other species or even shuffled over his hibernation underwater. Morton rejected this idea because it was too fantasy (not like his, of course). The arrow. Morton even calculated that the trip to the moon had a month away and another back, sleeping much of the time and surviving thanks to his body fat. The truth is that, in the absence of better theories, it was not bad (despite my jocular tone, we talked about the seventeenth century and the media they had). However, little by little the idea that these European birds were going to other places during the winter. And the definitive test was brought by a stork. A good day of 1882, north of Germany, someone shot a stork, who fell down and with a capital surprise for those present: he had an 8 -centimeter arrow through his neck. The question was no longer how I could fly with such a breakdown, but where the arrow had come from. Brava PFEILSTORCH. Thus, they took the body of the stork to the University of Rostock, where the researchers examined the projectile and concluded that it was an arrow belonging to some group in the center of Africa. As it was impossible, or tremendously unlikely, that someone launched something like that on European soil, the response became evident: that stork had traveled more than 3,000 kilometers from the point in Africa in which winter had passed and where it was killed in Germany. Baptized as PFEILSTORCHIt was dissected and preserved in perfect condition in the Zoological Collection of the University of Rostock thanks to its undeniable importance in the world of science and ornithology: it was confirmation to the suspicions that, indeed, migratory birds or became anything else, nor slept four months underwater or went to the moon: they traveled to the warmest places during the European winter. Clue. After Pfeilstorch (which means “Flechy stork” or “storks crossed by an arrow”), they found more specimens In Europe with the same characteristics: arrows stuck somewhere in your body. This is not so uncommon in large birds, which show great resilience to wounds that do not compromise flight or its basic functions. Once they are injured, if not seriously, the wound stabilizes and the bird can continue with its life. With the inclusion Of the rings on the legs of the birds by the Danish HC Mortensen in 1899, the researchers systematized the study of specimens to verify that those who flew from Europe before winter, disappeared and then returned, were the same. Thus, we can say that this arrow launched in Africa that landed in Germany was the first bird monitoring system, a coincidence that allowed obtaining the first conclusive data on the migratory practices of the birds.
