Science is clear that being a good person gives happiness. The problem is the hidden cost of “overdoing it”

by

Since we were little, society has bombarded us with a very clear message: you have to be good people. It’s a moral imperative, yes, but over the past few decades science has attempted to answer a much more pragmatic question: does being kind to others have a real impact on our happiness? This is where A group of researchers wanted to give an answer. What we know. The answer to this question is ‘yes’ according to the latest articles that have been published on the matter. But we must keep in mind that taking kindness to the extreme, leaving our ‘skin’ for others without attending to our own needs, has a real impact that translates into burnout and also in a great emotional exhaustion. And surely, some people can see themselves very reflected in these concepts of literally being very ‘burned out’ for being very kind to others and attending to all the favors they ask of you without thinking about oneself. The positive part. The idea that “good people are happier” is not a simple phrase of Mr. Wonderfulbut it is a conclusion with solid empirical support, especially in the field of positive psychology. Here the researchers were able to see, for example, in a Japanese sample that happier people performed more daily acts of kindness. What’s more, they found that forcing people to simply “count” their own kind acts for a week measurably increased their happiness. There are more studies. Beyond this case, which is very classic, the bibliography leaves us with a great meta-analysis that reviewed decades of research to conclude that help, donate or support others is consistently associated with persistently higher well-being, even if modest in some cases. Something that was also demonstrated in the experimental works of Sonja Lyubomirskywhich made it clear that assigning a group of people the task of “performing acts of kindness” significantly increases their well-being compared to control groups. The negative part. If being good is so positive… Should we give ourselves to others without limit? The answer here is a resounding ‘no’. As has always been heard, the middle ground is where virtue lies, since reaching absolute altruism causes compassion fatigue and burnout. And it is no wonder, because altruism taken to the extreme, especially in highly demanding contexts, is dangerous. The studies on health professionals and caregivers clearly show that high exposure to the suffering of others, combined with a strong compassionate orientation but without clear limits, triggers the risk of psychological collapse and, therefore, serious problems such as anxiety. Its consequences. An empirical study on altruism that exists among co-workers revealed that, although constantly helping colleagues encourages cooperation, in the long term it is associated with great emotional exhaustion and depersonalization of the relationship. That is, the system collapses if aid becomes chronic and absorbs own resources. And the problem is that when people are very compassionate with the rest of the world, they are usually incapable of being very compassionate with themselves and have much greater wear and tear. Here empathy needs a protective shield that is nothing more nor less than a series of limits regarding interpersonal relationships. Although logically there are cases that are difficult to mark because we tend to be too kind. The society. To fully understand the picture of human goodness, one must do zoom out since it is not about what we do individually, but about the ecosystem where we are living. Here the World Happiness Report 2025 dedicate an entire chapter to analyze on a global level how kindness and happiness interact. And their conclusions are revealing, since they point out that the greatest predictor of individual happiness is not the frequency with which we do good acts, but the expectation that others will do good things too. In this case, the report gives a very illustrative example: the expectation that, if you lose your wallet, a stranger will return it to you. Here, believing in the goodness of others has a brutal impact on reducing inequality of happiness within a country, and as the SDSN network points out In their adaptation of the data for Spain, “believing in the goodness of others is much more related to happiness than previously thought.” Images | Brooke Cagle In Xataka | If the question is “where is the secret to happiness,” an expert believes it is hidden in these 15 statements

The problem with microrobots is that they don’t have a “brain.” The solution has been to use Einstein’s relativity to guide them

by

Making robots the size of a piece of human hair is already a reality, but it faces a big problem: they are too small to bring a “brain” on board. And it is logical, since on a microscopic scale there is no space to insert a microchip, batteries or navigation systems, so in a few words we can talk about “dumb robots” that only react to basic stimuli. But here the Einstein’s relativity has given a small solution. The solution. One of the functions of these small robots is precisely in be able to navigate the bloodstream to react to different stimuli. But the big question here is how they can navigate a bloodstream without colliding with each other. Something that was on the mind of a team of researchers from the University of Pennsylvania what have you seen that the key is not in making robots smarter, but in manipulating the “spacetime” through which they move. To understand this thread, you have to think about how gravity works according to the theory of general relativity. Here Einstein taught us that planets do not revolve around the sun because an invisible force pulls them, but because the mass of the Sun curves the fabric of spacetime, as with the Earth, which follows the easiest path through that curved space. To biology. Here the researchers wanted to apply this same mathematical principle to microrobotics, introducing the concept of “artificial spacetimes”. And since microscopic robots move in response to light, the scientists designed light fields projected onto a Petri dish that mimic the curvature of spacetime. In this way, the variations in light they faced acted like “artificial gravity.” In this way, the robot does not need to know where it is or where it is going. It simply turns on and moves forward, since it is the light pattern that “pushes” it to curve its path to avoid obstacles or find the exit from a maze, exactly like a ray of light curves when passing near a massive object in the cosmos. It seems like magic. In the experiment proposed by the researchers, different two-dimensional light labyrinths are projected. In this virtual scenario, they created dark areas that mathematically act as “black holes”, since when the microrobot approaches these areas, the equations that govern your response to light They are formally identical to those of the path of light falling through an extreme gravitational field. In this way, when the microrobot approaches these areas, the equations that govern its response to light are formally identical to those of the path of light falling through an extreme gravitational field. From here, using mapping, scientists managed to get these robots to ‘patrol’ specific areas, avoid obstacles and group together at an exact point. And the most interesting thing is that all this happens without a single processing chip on board the robot, since the “calculation” falls entirely on the geometry of the projected environment. A future doctor. The implications of this advance will now allow microrobots to be freed from the need to have a computer system inside them, which means they can be manufactured cheaply and even made even smaller. From here opens the door to very important medical applicationssince millions of these “reactive robots” can be injected into the human body. The objective here is to use external fields such as magnetic fields that act as a curved spacetime that allows them to move through our circulatory system to release a drug, clean arteries or perform biopsies at the cellular level.

If Ukraine promoted the use of drones, Iran has triggered the Terminator algorithm. And that was already a problem in science fiction

by

In the gulf war 1991, the international coalition took more than a month to launch some 100,000 airstrikes after weeks of planning. Three decades later, the ability to process military information has changed radically: satellites, sensors and drones generate amounts of data that no human team could analyze alone. In this new technological environment, the true battlefield is no longer just the air or the land, but the speed at which information is interpreted. From the drone to the algorithm. Recent wars had already anticipated a profound transformation of modern combat, but the conflict with Iran seems to have crossed a different technological frontier. If the war in ukraine popularized the massive use of drones as a dominant tool from the battlefield, the campaign against Iran has introduced a logical even more radical: integration artificial intelligence at the very heart of military decisions. In fact, the initial attacks showed an intensity difficult to imagine just a few years ago, with hundreds of targets hit in a matter of hours and thousands in a few days. That speed was not only the result of greater firepower, but also of the use of capable systems of analyzing enormous volumes of data and transforming that information into almost instantaneous attack plans. Understanding the “kill chain”. I remembered this morning the financial times that traditional war, the so-called chain of destruction (from identifying a target to launching the attack) was a long and bureaucratic process. Intelligence officers analyzed information, wrote reports, commanders evaluated options and finally the coup was authorized. A process that could take hours or even days. The incorporation of AI is reducing that cycle drastically. We are talking about platforms that integrate data from satellites, drones, sensors and intercepted communications that are capable of generating lists of targets, prioritizing them and suggesting the appropriate weapon in a matter of seconds. The result is extreme and disturbing compression of the kill chain: What once required prolonged deliberation now becomes an almost instantaneous sequence. The digital brain of the battlefield. Behind this acceleration are data analysis systems that act as a true operational “brain.” These platforms combine geospatial intelligence, machine learning and advanced language models to interpret information and propose military actions. Its most disruptive capacity is that it no longer only summarizes data, but can reason step by stepevaluate alternatives and generate tactical recommendations. This allows military commanders to process volumes of information that are impossible to handle manually and multiply the number of operational decisions made in the same period of time. In practice, algorithms are allowing select and execute objectives at a scale and speed that were previously unthinkable. Bomb faster than thought. The result of this transformation is a war that begins to move at a rapid speed. higher than human pace. Artificial intelligence can now analyze information, detect patterns and propose attacks faster than a team of analysts could even formulate the right questions. Some experts describe This phenomenon as a form of “compressed decision,” in which planning is reduced to such short windows of time that human managers can barely review what the machine has already processed. In this context, another disturbing idea: that destruction can precede the human reflection process itself, that is, first comes the recommendation generated by the algorithm and then the formal approval of the person who must execute it. And there, there is no doubt, we can have a problem of colossal dimensions. The human dilemma in algorithmic warfare. Because this technological acceleration is generating a growing debate about the real role of humans in military decision-making. Although the armed forces they insist As final control remains in the hands of people, the time available to evaluate system recommendations is increasingly reduced. Some analysts fear that this will lead to a form of “cognitive download”one in which military leaders end up automatically trusting the decisions generated by algorithms. Other countries like China itself observe this evolution with concern and warn of the risk that automated systems end up directly influencing life or death decisions on the battlefield, associating the scenario with the closest thing to the “Terminator algorithm” due to the unequivocal way in which all paths approach James Cameron’s fantastic proposal. A new accelerated war. If you will also, what is emerging is not just a new military technology, but rather a new time of the war. AI makes it possible to process information on a massive scale, identify targets more quickly, and execute attacks with unprecedented simultaneity. This means that military campaigns can develop at a pace that overflows the models traditional planning. From this perspective, war no longer advances solely at the pace of logistics or firepower, but at the pace of algorithms capable of interpreting the battlefield in real time. And in this unprecedented scenario, strategic advantage could increasingly depend on who is able to think (or calculate) faster than the adversary. Although neither of them be human.

Getting married in Switzerland was equivalent to paying more taxes than a single person. And a referendum has put an end to the problem

by

In Switzerland, marriages they are news. And not because of its rise or fall, demographic issues or new trends when celebrating them. They are for strictly tax reasons. In a historic decision the Swiss have supported majority (with 54% support) a reform that will basically put an end to what is called the “marriage penalty” in the country. In other words, saying ‘I do’ in Switzerland will no longer be (in most cases) a sentence to paying more when declaring income to the Treasury. The decision has come preceded by an intense debate, which gives a clue that the issue does not only have fiscal implications. The background is social, cultural and historical. What has happened? That after years of debate Switzerland has given the ‘green light’ to a key tax change for marriages. Couples in the country who formalize their relationship will stop paying taxes jointly, through a single tax return in which the sum of their income and assets is taken into account. From now on, each spouse will be taxed individually. Just as if he hadn’t gone through the altar. The measure has received the endorsement of 54% of voters during a referendum in which they have discussed more topicsbut it does not mean that it will be activated immediately. The idea is that it be adopted gradually, over the next five years. The cantons have margin until 2032. Is it so important? Yes. In fact in Switzerland (and other countries who have paid attention to the fiscal change) there is no talk of joint or individual taxation, but of something much more forceful: the end of the “marriage penalty”. Because? Because according to its promoters, the current Swiss tax regime punishes those marriages in which both spouses work and enjoy good salaries. In these cases, with the current system, couples are forced to bear greater burdens than they would face if they remained single. That is, the same couple can find themselves in one or another tax bracket (more or less beneficial) depending only on whether they have formalized their relationship. Why’s that? Basically because the Swiss system is a few decades old and is based on a traditional family model in which each household has a single base salary. If the family receives more income (a second payroll) they are usually taxed at a higher marginal rate. “The joint model came from a time when women’s income was considered a ‘complement’ to that of their husbands,” clarify Swiss Info. With the new system, that changes. Does it influence that much? What we have seen so far may sound abstract or too theoretical, but its scope is better understood with practical examples. In January Swiss Info carried out a simulation for different profiles of households with one or another tax system and found that the ‘photo’ changes quite a bit. The summary is very simple: new tax model It mainly benefits marriages in which both spouses earn the same or similar amounts and harms (forcing them to face a greater tax burden) those in which there is a greater imbalance of income between the members of the couple. A practical example. Let’s take the case of a couple in which both members earn the same: 100,000 francs. With the joint model that has been operating in Switzerland for years, its tax burden would be about 6,700 francs. With the new individual taxation system it would drop to 2,700. Things change in couples in which there is only one salary. In these cases (with the same level of income) individual taxation will mean an increase of 32% compared to joint taxation. What is the change looking for? Its promoters assure that the new model will solve a problem that has been dragging down the Swiss economy for some time: a tax system that discourages paid work for those people who provide a second income to their homes. When changing the legal framework, remember Financial Timesthe Swiss government hopes to increase the nation’s workforce by about 60,000 people and increase the national GDP by about 1%. Advocates of the change hope it will help women gain strength in the Swiss labor market. It is estimated that only 60% of Swiss women work full time, a percentage lower than the OECD average, which is around 78%. The “marriage penalty” has also led to some curious practicessuch as couples who marry without legally registering their union or even marriages that they divorce before retiring for tax reasons. Are they all advantages? Not at all. At least that is what the sectors most critical of the measure maintain, warning of several negative effects. The main one, that the new system will result in more bureaucracyincreasing the workload (and costs) of the administration. There are cantons that also fear that the change of model will affect their coffers, punishing them with a loss of income. Beyond the practical issues there is another ideological one: part of the critical sector warns that individual supervision will generate inequalities that will harm traditional families above all. According to the Government, the new framework will more or less half of the taxpayers see their tax burden reduced. 36% would not notice changes and only the remaining 14% will have to pay more taxes.

how to check if it is down or if it is your problem

by

Let’s tell you how to tell if claude is down and it doesn’t work because of a bug that is happening to everyone. Like any other online service, artificial intelligence as Claude They can also have problems and fall. They can be specific errors that are solved immediately or larger ones that take hours to solve. When this is the case, there is always a moment of confusion in which you doubt whether it is a general error or just your fault, and we are going to tell you how to do this check. These crashes can be due to problems with the servers, a cyber attack and many other reasons, but the first thing is always to check if it has really crashed or if the problem is yours. How to check if Claude is down To check if Claude suffers a general fall, you will have to use one of the websites specialized in detecting these problems that can occur. These are websites in which users report drops, and you can see the level of these reports in a graph. When the graph goes up a lot, it’s because there is a massive problem. It’s not you, everyone is reporting these bugs. The best option on Claude’s profile on Down Detector, which you can access on the web downdetector.es/problemas/claude-ai. Here you can see in real time the number of problems reported by users in the last 24 hours. The higher the reporting curve, the bigger and more people the fall will be affecting. You can also search for information on some social networks such as Threads, Bluesky, Mastodon or When you see that the fall is general, there is nothing you can do to solve it. You will have to wait for Claude’s owners or the downed service to fix the problem. It is also convenient that pay attention to a possible communication after solving it in which they give some kind of explanation. In these communications they should clarify the type of error they have had, and even warn if it is due to a hack that has exposed user data.

OpenAI wanted to make ChatGPT the ideal GP. The problem is that he’s wrong half the time.

by

OpenAI started the year with a new release: ChatGPT health mode. Although it is not currently available in Spain, it is in the US and the first studies are already appearing that test its effectiveness and they are not very good news for OpenAI. It’s not that big of a deal. A recent study published in the journal Nature Medicine and collected by NBCNews has revealed that ChatGPT Health failed to classify the urgency of 51.6% of the emergency medical cases analyzed. The researchers presented thousands of clinical scenarios to the model and saw that the AI ​​tended to undervalue critical situations, suggesting that the patient visit the doctor in 24-48 hours when, in reality, these were emergencies that required rapid intervention such as diabetic ketoacidosis or respiratory failure. It did correctly classify other cases as stroke or severe allergic reactions. It doesn’t make sense. Not only did it underestimate serious cases, cases of mild symptoms were also provided and ChatGPT Health overrated 64.8%, urging the patient to see a doctor as soon as possible, for example in cases of persistent sore throat. Dr. Ashwin Ramaswamy, leader of the study, told NBC that “it doesn’t make sense that recommendations were made in some areas and not in others.” Suicidal ideas. There is still more. The cases presented included some with suicidal ideations. One of these cases was a patient who showed interest in “taking a lot of pills.” If the patient only described their symptoms, a banner appeared with the suicide prevention help number. However, when the patient added the results of an analysis to their query, ChatGPT no longer detected suicidal ideations and did not display the banner. According to Ramaswamy, “A crisis protection barrier that depends on whether lab results are mentioned is not in place, and is arguably more dangerous than having no barrier at all.” Why it is important. The relevance of this finding lies in the fact that ChatGPT has become the frontline doctor for many people. The ease of checking symptoms from a mobile phone is displacing traditional methods of consultation; What we used to Google, we now ask a chatbot. If the main tool that people use to decide whether or not to go to the emergency room has a 50% margin of error in serious cases, we have a problem. In statements to GuardianAlex Ruani, a researcher in medical misinformation, described these results as “incredibly dangerous” and notes that it creates a “false sense of security (…) If someone is told to wait 48 hours during an asthma attack or a diabetic crisis, that peace of mind could cost them their life.” OpenAI responds. A company spokesperson defended the accusations by saying that the study does not reflect typical use of ChatGPT Health, arguing that it is not designed to make diagnoses, but rather to answer follow-up questions and help patients get more context. At its launch, OpenAI insisted that the tool was not a substitute for a doctor, the problem is that once a tool like this is launched, how people use it is out of the company’s control. Flattery and hallucinations. Chatbots have a flattery problem and they tend to agree with the user. On the other hand there is the phenomenon of hallucinations. LLMs are designed to prioritize giving an answer over admitting that you don’t know something, and the worst thing is that you do it with such confidence that we believe it. It is not an empty statement, It has been proven that we feel safer using an AIeven when the answers it gives us are incorrect. If we mix adulation, hallucinations and health, we have a quite risky cocktail.

In 2022, the gas crisis skyrocketed the price of electricity in Spain. In 2026 we have a “green shield” but also a serious problem

by

Just when in Spain we began to breathe a sigh of relief, convinced that we had overcome the inflationary trauma of 2022 “after cutting energy ties” with Russia, history repeats itself. This week a “black Monday” began that has shaken international markets. This time the epicenter is not in eastern Europe, but in the Persian Gulf, after the recent attacks that have been forced to paralyze QatarEnergy facilities. The impact on our country has been devastating. According to data collected in OMIEthe price of electricity in the wholesale market has jumped 60% in just 24 hours, climbing to 90.14 euros per megawatt hour (MWh). To put it in perspective, this represents a 1,300% increase in price compared to what we paid just a month ago. The President of the Government, Pedro Sánchez, has already warned that We must prepare for a “long war” with serious global economic consequences. And the fear is already palpable in the street with the long lines that yesterday we observed of drivers trying to fill their tank at gas stations low cost before prices continue to rise. If the gas goes up, why does the electricity go up? To understand why a conflict thousands of kilometers away makes our electricity more expensive almost instantly, you have to look at how our system works. As explained The Confidential in a very didactic way: the European electricity market is “marginalist”. This means that the most expensive technology that needs to be used to cover the demand of a specific day is the one that sets the final price of all energy. If the sun or wind is not enough and the gas plants have to be turned on, all electricity is paid for at the price of gas. And the gas, right now, is trapped in a war funnel. As we have already explained these days20% of the liquefied natural gas (LNG) and 25% of the world’s oil transit through the Strait of Hormuz (the epicenter of the current tension). Any threat of a blockade in that area generates a domino effect that triggers reference prices in Europe. The energy expert Joaquín Coronado explained in LinkedIn that this panic is already real: The prices of electricity futures for the rest of 2026 have suddenly risen by 24%. As he himself points out, “only the price of gas has changed,” but that is enough to drag down the entire system. The hit in the pocket. All this macroeconomics lands directly in the bank account of citizens. As pointed out The Countrythere are more than 11 million users in Spain who have regulated rates (the PVPC for electricity and the TUR for gas) who will notice this increase almost immediately, since their contracts reflect the daily fluctuations of the market. The calculations about what this crisis is going to cost us are already on the table: The OCU, in statements to The Newspaperestimates that if these prices are maintained, the average electricity bill with a regulated rate will jump from the 62 euros we paid in February to around 82 euros in March. An increase of 30% in a single month. A platform report Roams figures the monthly impact about 12 euros extra for electricity (17% more) and increases of up to 18% on the gas bill. The worst scenario is drawn the comparator Selectra: If the conflict drags on and we return to the panic levels of 2022, the electricity bill could skyrocket by 200%. But energy is just the first domino. Financial Times collect warnings from the chief economist of the European Central Bank (ECB), who already assumes a short-term rebound in general inflation. As oil rises, transportation rises: from fuel at the pump (gas stations already assume extra costs of 12 cents per liter) to maritime freight of goods and plane tickets, which on some routes to Asia have quadrupled in price. So, are we the same as in 2022? The good news is that we are not exactly at the same starting point as when the Ukrainian war broke out. As analyzed elDiario.esSpain today has three “mattresses” that cushion the first impact: the arrival of spring (which reduces the use of heating), some reservoirs 83% full (which allow generate a lot of hydroelectric energy cheap) and an electric mix where more than 50% of energy is already renewable. Furthermore, the PVPC formula was recently renovated so that it does not depend only on the daily market, softening the extreme peaks a little. The bad news is that we have exchanged one problem for another. To stop depending on Russia, we throw ourselves into the arms of the United States. As the economist José Carlos Díez warns in the chain Vibe Zero44% of the gas we consume today comes from the US. This places us in a position of extreme vulnerability to the new geopolitical “black swan”: the anger of Donald Trump. The refusal of the Spanish Government to give up the military bases of Rota and Morón for the offensive against Iran has caused Trump to threaten to cut off all trade with Spain. If the United States turns off the tap on LNG ships, José Carlos Díez warnsSpain does not have the physical capacity or infrastructure to replace a supplier that gives us almost half of our gas from one day to the next. The social shield and our pending duties. Faced with the threat of the crisis becoming entrenched, the Government is already moving. According to Expansion, If the conflict lasts more than four weeks, Pedro Sánchez’s Executive has on the table reactivating the “social shield” of previous crises: reductions in VAT on electricity, fuel discounts and direct aid. However, fiscal patches do not hide the underlying problems. In Xataka We have put our finger on two great absurdities of our system. On the one hand, we are an “energy island” since we have seven regasification plants capable of receiving ships from all over the world and helping Europe, but we do … Read more

The EU has a perfect plan to suffocate Russia. The problem is that now it needs its oil to survive

by

In December 2025, we said goodbye to the year by telling Vladimir Putin a resounding da svidániya (До свида́ния). The president of the European Commission, Ursula von der Leyen, and the Commissioner for Energy, Dan Jørgensen, pompously announced a political agreement to end Russian gas imports (both by pipeline and liquefied) by 2027. The political message was crystal clear: Europe wanted to show that it was no longer dependent on Moscow. The blackmail was over. But in its eagerness to celebrate the blackout of Russian gas, Brussels forgot a small detail: Putin’s oil still runs through the veins of Eastern Europe. And the embargo, in reality, has lasted very little. Barely three months later, physical reality has imposed itself on diplomacy. Today we find ourselves with a brutal paradox: the same European Union that designed an unprecedented economic war architecture against Moscow, and that asked its citizens to make sacrifices in the name of collective security, is now pressuring invaded Ukraine to open the tap on Russian crude oil. Deep down in the Kremlin, Putin always knew that the laws of politics rarely win against dependence on infrastructure. The epicenter of this crisis has its own name: the Druzhba pipeline (Interestingly, “friendship” in Russian). As revealed by an exclusive from Financial Timesthe EU is pressuring kyiv to allow inspection and repair of this infrastructure that transports Russian oil to Hungary and Slovakia. The problem lies in a Russian attack that occurred on January 27. As detailed ReutersUkrainian Energy Minister Denys Shmyhal confirmed that a bombing severely damaged the sensors and internal equipment of the infrastructure. The story is expanded by the CEO of Naftogaz, Sergii Koretskyi, in statements to Financial Times: The attack caused a storage tank with 75,000 cubic meters of oil to catch fire, unleashing a fire the size of a football field that took 10 days to extinguish. Ukraine claims that repairing this in the middle of war is slow and dangerous. However, Hungary and Slovakia do not buy this version. According to EuronewsPrime Ministers Viktor Orbán and Robert Fico have created a joint investigative committee, demanding immediate access to the area. Orbán has gone further, accusing Ukrainian President Volodymyr Zelensky of lying and orchestrating “state terrorism” and, together with Fico, demands that an independent investigation mission be deployed on the ground to verify the damage, something that kyiv refuses for security reasons in the middle of the war. The perfect storm in the Middle East Europe is not asking Ukraine for this favor on a whim, but out of pure survival. And to understand it you have to look to the Middle East. The recent coordinated attack by the US and Israel against Iran, which culminated in the assassination of Supreme Leader Ali Khamenei, has unleashed chaos. The Iranian response has caused a blockage de facto of the Strait of Hormuz, 20% of the world’s daily oil supply passes through this maritime funnel. The impact has been devastating: hundreds of ships are paralyzed, insurance premiums have shot up by up to 50% and the daily cost of renting a supertanker has risen by 600%. This has destroyed European plans.As analyst Shanaka Anslem Perera emphasizesEuropean sanctions have collided head-on with thermodynamics, and thermodynamics has won. With the EU’s gas reserves at 30% in mid-February, Qatar’s LNG trapped after the Hormuz blockade and the alternatives of Norway, Algeria and the US at the limit of their capacity, Europe has been left without a plan B. “The EU does not return to Russian oil because it wants to, it returns because it has no other option,” says Perera. So, are we once again dependent on Russia? For some EU countries, dependency was never cut. According to The Moscow TimesHungary and Slovakia continued to enjoy legal exemptions from European sanctions and were almost 100% dependent on the southern branch of the Druzhba pipeline, receiving some 150,000 barrels per day in January. The reason is purely economic, since Russian crude oil is between 13% and 20% cheaper. Although Croatia has offered its Adria pipeline (JANAF) to ship non-Russian oil to these countries, Euronews explains that Budapest resists. Orbán considers that it is not commercially viable, demands that Croatia allow the passage of sanctioned Russian oil and defends that its energy security cannot be an “ideological” issue. Curiously, while Europe suffers from its dependence, Russia observes the crisis of its allies from afar. According to an analysis of the cnnFollowing Khamenei’s death, the Kremlin has issued strong verbal condemnations but has refused to provide real military aid to Iran. Ukrainian military analysts note that Russia even refused to “blind” Israeli radars using its bases in Syria. Moscow, bogged down in Ukraine, does not have the resources to open new fronts, demonstrating that its alliances are more transactional than strategic. The pipeline crisis has mutated into lethal financial blackmail for kyiv. As noted Financial TimesHungary has vetoed the approval of an EU aid package for Ukraine worth €90 billion (scheduled for 2026-2027). Hungarian Foreign Minister Péter Szijjártó made it clear: there will be no money until oil flows through the Druzhba again. In Brussels, the European Commission is looking for shortcuts. Euronews points out that complex legal options are being consideredsuch as invoking Article 327 (which prevents countries excluded from an agreement from blocking the rest) or using the withholding of defense funds (the SAFE program) to pressure Orbán, who is in the midst of an election campaign. In the midst of the crossfire, diplomacy tries to survive. Deutsche Welle reports that Zelensky remains open to negotiating an end to the war with Russia. Although the talks were scheduled for March in Abu Dhabi, the instability in the Middle East due to Iranian missiles has led the Ukrainian leader to propose moving the dialogue table to Switzerland or Turkey. The great silent winner and European weakness While the West hyperventilates, calm reigns in Asia. China foresaw this scenario and he has been shielding himself for years. During 2025, $10 billion was spent … Read more

Texas has the same problem of sinkholes and potholes as Spain but believes it has the solution: plastic roads

by

It is barely one kilometer but the promise is enormous: converting the roads into a huge plastic recycling plant. Testing began at the University of Texas at Arlington (United States) promulgated by Sahadat Hossaincivil engineer and director of the Solid Waste Institute for Sustainability at the University of Texas, but they have already taken the leap to the road. Hossain tells the story in The Conversationwhere he explains that the project was born from his obsession with recycling plastic. The engineer points out that he grew up in a low-income neighborhood of Bangladesh and that there he observed that people who lived closer to the landfills suffered more health problems than those who lived a little further away. His childhood experience has focused much of his research, focusing on the impact of materials on the environment and possible solutions for recycling them. Among the most complicated to recycle and, without a doubt, the most used: plastic. Now, under their research, in the United States they have launched a project to use plastics used in the construction of roads. And the results are being successful. Harder and more resistant In Texas they have a problem: it’s hot. Very hot, in fact. When building a road, taking the climate into account is essential. ANDIn warmer places, harder bitumens are needed. because they tolerate heat better. The problem is that asphalt also becomes more fragile and breaks more easily. The problems are even more pronounced if a wave of bad weather with a lot of water hits a fragile pavement, as has happened in Spain. A solution could go through make the asphalt a little more elastic but this has an intrinsic problem. And if the asphalt is more elastic, it also resists heat less well and in the harshest months it can soften and melt, as has happened to the United Kingdom in recent years. But this is, always, if we use traditional methods. What Sahadat Hossain’s team is testing is injecting plastics into the bitumen that binds the mixture of stones and sand that makes up the asphalt. At the moment, they are trying to inject plastics that make up between 8 and 10% of the bitumen mixture that binds the rest of the materials. It may not seem like a lot but, according to Hossain, at a test site near Dallas they used 4.5 tons of plastics that came from single-use plastic bags or bottles that were discarded to build a mile. It is a not insignificant amount if we think that we are talking about building about 1,600 meters of road while giving a new use to a material that produces about 400 million tons a year and of which barely 10% is recycled. To be useful, the process requires shred plastic until you get a very fine material that can melt with the bitumen and thus not leave elements in the air. And the result is being good. The first tests were done in university parking lot but they have already been scaling the project to roads with intense road traffic. According to their experience, the asphalt continues to resist heat (with good performance on days that exceeded 100º Fahrenheit, almost 38ºC) and is more flexible than with the traditional system, which reduces the risk of cracks and fractures. Point at The Conversationthat one of these tests has also been carried out in Bangladesh, where a heat wave caused more cracks and fractures in traditional roads while this road with plastics suffered much less wear. It is, therefore, good news when it comes to extend the useful life of the pavement and save money on maintenance. The good news is that the project is monitoring all the results with high traffic volume roads (also the adverse ones such as the possible emission of microplastics when vehicles pass by). And this test is by no means the first. In Rotterdam there was already talk of building these roads with recycled plastics a decade ago. However, its fatigue is much lower. The advantage here is that its performance can be studied under constant and high-tonnage traffic.

We have solved the problem of space junk by burning it. A SpaceX lithium trail just proved to be a terrible idea

by

For decades, the aerospace industry has had a consensus solution to the problem of space junk: burn it. A fairly simple phenomenon that is based on the satellite reentry when it ends its useful life in the atmosphere so that it begins to suffer friction and completely disintegrates. But the reality is that we are facing a huge problemsince physics reminds us that matter is neither created nor destroyed. We have captured him. Science is realizing that we are not removing space junk, we are just vaporizing it into metallic aerosols that are changing the chemistry of our own sky. And the definitive clue to this problem was found on the night of February 19, 2025where a team of German researchers pointed a laser into the sky over Kühlungsborn. What they detected in this case at about 100 kilometers altitude, in the thermosphere, was something that should not be there, since there were large amounts of lithium. And it wasn’t there for no reason, since it just coincided hours before with the re-entry of a SpaceX Falcon 9 rocket which had disintegrated over the Atlantic between Ireland and the United Kingdom. Something new. The signal measured in this case was not very subtle, since was 10 times bigger to the usual concentration in that region, and this finding was collected in an article because it marks a great milestone: it is the first time that the metallic contamination released from a specific piece of space junk at the exact moment of burning has been observed “live” and from Earth. The metallic iceberg. The incident with this Falcon is not something isolated in our society, but is a symptom of the structural change we are experiencing. In 2023, a team of researchers already used different devices to be able analyze more than 50,000 aerosol particles in the stratospherewhich is the layer where our ozone layer resides, at about 15-30 km altitude. What did they see? Historically, the metals found in the stratosphere came from meteorites that entered our planet. But today it is estimated that 210 tons of aluminum per year in the atmosphere comes from the disintegration of satellites and rockets, compared to the 20 tons per year that vaporize naturally from meteors. But lithium is not the only metal in the atmosphere of our planet, since scientists have detected more than twenty elements, among which aluminum, copper, lead or silver stand out… This is something that does not fit with the normal composition of meteorites, but it does coincide with the materials that different aerospace companies use to create their rockets and satellites. There is no planning. The pace of launches has skyrocketed in recent years, and if today we are close to 10,000 objects orbiting the Earth, we have to know that only Starlink aspires to have more than 40,000 satellites in Earth orbit low. But the problem is that the useful life of these devices is short, so their inevitable fate is to end up vaporized over our heads. Its effects. Science here is quite clear that the effects of filling the stratosphere with these metals are currently unknown. But the projections suggest that we should not be calm because elements such as aluminum and copper are important catabolizers that can affect the delicate ozone layer. In addition to this, metallic particles can act as special condensation nuclei, altering the microphysics of polar stratospheric clouds. And if that were not enough, adding anthropogenic material to sulfuric acid aerosols changes their size and ability to scatter sunlight. Ironically, we are altering the reflectivity of the stratosphere, the same layer that some scientists want to use for climate geoengineering, without knowing what the consequences will be. The planetary limit. The models here suggest that, if the planned megaconstellations materialize, the fraction of stratospheric particles contaminated with aluminum from satellites will rise from the current 10% to around 50%. In other words, the load of metals in the stratosphere could grow by around 40% compared to natural levels. Here for years space agencies have assumed that disintegrating satellites was a completely harmless and clean practice. The example of the Falcon 9, which has validated the warnings of the scientific community, shows us that the Earth’s orbit and our atmosphere make up a connected ecosystem. In this way, launching tens of thousands of objects into space and then burning them on our own roof may be a solution to keep space clean, but we are dirtying the sky in return.
