Renfe has found a new way to make life impossible for Ouigo and Iryo. And it has nothing to do with lowering prices.

by

Renfe maintains a hidden war with Ouigo and Iryo. Beyond the headlines and the exchanges of more or less high-sounding statements, the Spanish company and its rivals fight on all types of grounds. Also outside the train tracks and the most obvious sources of business. And here, the use of workshops has a lot to say. What has happened? Renfe has prevented Iryo from using its workshops so that the company can carry out heavy maintenance on its trains. The information is brought The Economist and it states that the Spanish company has rejected Italians’ access to its facilities because they consider that the activity to be carried out there exceeds the obligations they have towards their rivals. In Xataka We have contacted both companies but as of this writing we have not received answers to our questions. The obligations. Although the facilities belong to Renfe, the Spanish company has the obligation to allow access to its workshops at specific points in Spain so that Ouigo and Iryo can carry out their maintenance operations. However, this obligation is limited to light maintenance, known in the sector as “level 1” maintenance. This scale of what falls within “light” or “level 1” maintenance and what are “heavy” or “level 2” maintenance interventions are those that have been questioned by Renfe. The company is clear, Iryo wants to carry out operations of this second category and they are not obliged to give access to their workshops for this type of tasks. The CNMC. Given the denial of access to the workshops, Iryo went to the CNMC to mediate the matter. The National Markets and Competition Commission ruled in March that Renfe had to give Iryo access to its facilities where Hitachi employees would carry out maintenance services on Iryo trains. Although Renfe, Iryo and Hitachi seemed to have reached an agreement for the latter company (manufacturer of Iryo trains) to carry out maintenance at Renfe facilities, the Spanish company indicated that this could not be carried out because heavy maintenance activity related to Renfe trains had skyrocketed and there was no space left for such actions. Given this situation, Iryo requested provisional measures from the CNMC to access “an operational pit at BMI La Sagra or, subsidiarily, at BM Santa Catalina, on a self-provision basis, for the execution of heavy maintenance (R2) of the ETR 1000.” An access that the CNMC decided to give. The reasons. The CNMC pointed out in its resolution that denying Iryo access to the workshops directly damages the business plans that it has for our country since it would force the trains to be taken to Italy to undergo said heavy maintenance. For Renfe, this should not be a problem but the CNMC rejects this position of the Spanish company. Iryo trains approach the mileage limit before passing through workshops for a thorough inspection. When Iryo arrived in Spain, it stated that it would have its own workshops where it would carry out its maintenance. However, this has not occurred. However, the CNMC forces Renfe to provide access to its facilities to carry out these tasks, with the rates that were negotiated in the summer of 2025. Not compliant. In clear rejection of the CNMC’s decision, Renfe requests the Contentious-Administrative Chamber of the National Court to stop this decision and asks the CNMC to quarantine the decision until the National Court confirms what measures should be taken. The National Court, however, does not find it serious enough to apply precautionary measures, although it does confirm that it is opening a file to study the matter in depth. With this decision, the CNMC remains firm and once again forces Renfe to make way for Iryo trains in its workshops so that Hitachi workers can carry out scheduled heavy maintenance. It’s not the first time. Although we have talked about Iryo so far, the truth is that Renfe is not the first time that it has denied entry to its workshops to one of its rivals or, at the very least, has put up all possible impediments. In October of last year, the situation was very similar although, on that occasion It was Renfe and Ouigo who led the conflict. The reason was the same, according to Renfe the activity that Ouigo wanted to carry out in his workshops exceeded his company’s obligations to lend its facilities to carry out light maintenance. The fight between the three companies is tough because if Iryo and Ouigo do not get access to the Renfe workshops, they have to send their trains to Italy and France, respectively, where they do have their own workshops. That, of course, temporarily takes some of its trains out of circulation, which undoubtedly benefits its competitors.

what to do now with your life

by

It was in 2023 when Louis Debouzy sold his companyhe got paid, and found himself with an anxiety that he couldn’t explain. Within five months, 200 founders had signed up for The Exit Clubthe community he founded to talk about it. Most showed symptoms of depression. Why is it important. The phenomenon has a name in psychology: sudden wealth syndromeor sudden wealth syndrome. But in the case of the founders there is an additional layer: it is not just the money that arrives suddenly, it is that the company was their identity. When they sell it, what organized their time, their decisions, and basically their sense of who they are disappears. The calendar that was once bursting with meetings is suddenly empty. Without an agenda there is no identity. Between the lines. The entrepreneurial culture has built the exit like the definitive destination, the moment when everything makes sense. It’s celebrated on TechCrunch, applauded on LinkedIn, included in X’s bio, and talked about at any event. networking. What is not usually discussed is what happens the following Monday. Almost all founders experience deep and prolonged sadness after selling your companyeven when the exit has been a success. The problem is not failure but the opposite. The cases. The best-known examples are the most extreme, but not the only ones. These are extreme cases but they illustrate a logic that is repeated: financial success does not resolve the existential crisis, and in fact sometimes triggers it. The context. 72% of entrepreneurs have difficulties with mental health after the exitwhether it be depression, anxiety or addiction to some substance. 72%. It’s almost the norm. And yet, the taboo remains enormous: admitting that one has become depressed after winning millions clashes squarely with the social expectation that one should be euphoric. The post-periodexit It is a very lonely experience, because people expect you to just be happyand there is no guide to get through it. The question. Why does it take so long to talk about this normally? Probably because it combines two taboos: that of mental health and that of privilege. It’s hard to ask for empathy when eight figures have just arrived in your checking account. The absence of this social permission pushes the problem inward, and aggravates it. Groups like The Exit Club try to break that isolation: a space where you can say “I have all the money in the world and I don’t know who I am” without anyone looking at you strangely. It is not a new phenomenon for Xataka: The question of what to do with life when money is no longer the problem has been looming for years in forums and entrepreneurial communities. Yes, but. Not every founder who sells his company falls into a crisis. Some experience it as a liberation and move on to the next phase without apparent trauma. The problem is not universal, but it is frequent enough that communities, resources and therapists specialized in this specific transit have emerged. That there’s a market for that, especially in a demographic as small as “people who sell their business and get a completely life-changing amount” says something. Go deeper. The post-exit It is not a problem with a solution, but a transition with phases. What matters is recognizing it as a predictable phenomenon that affects high-performing people when their main source of identity disappears.

We’ve found molecules linked to life on Mars, but let’s not break out the champagne just yet

by

The Curiosity rover has carried out a chemical experiment on Mars that has never been done on another planet. Thanks to it, it has detected organic molecules that until now had gone unnoticed by us. Does that mean that there is or was life on the red planet? It could be, but it could also be due to many other things. Although we always read this type of news with joy and it gives a lot of sensational headlines, we must analyze the results with the optimism of what they mean for science, but the caution of what they imply in the search for extraterrestrial life. Chemical advances millions of kilometers away. Curiosity’s SAM instrument has carried out an experiment known as thermochymolysis. In it, a reagent called tetramethylammonium hydroxide (TMAH) is used. to break large molecules into small fragments. Thanks to this, organic molecules can be detected that are invisible with other methods. Among other organic molecules, some rich in nitrogen have been found, which could be related to DNA synthesis. The discovery of benzothiophene, present in some biological processes, also stands out. Let’s not go up. The authors of the study that has just been published thanks to the Curiosity rover they call for caution with its results. They insist that all the molecules found could come from abiotic processes or have reached Mars from other points in space. For example, benzothiophene could be formed by geological or hydrothermal processes. In addition, its presence has been found in meteorites and asteroids on Earth. It could also have reached Mars like this. Only two tries. Regardless of whether the findings have to do with life or not, this study is very relevant for two reasons. On the one hand, because it was the first time that this experiment could be carried out outside of Earth. And, secondly, because Curiosity I only had two tries to do it, but he made good use of them. This is because TMAH was in the exact dose needed, inside two sealed capsules. If the first failed, the second could be tried. If this one did it too, goodbye experiment. That it was done without problems has been a great achievement. This is an annotated close-up of three holes that NASA’s Curiosity drilled into Martian rock at a location nicknamed “Mary Anning” in October 2020. The sample where the rover found a large number of organic molecules came from “Mary Anning 3.” (A nearby site nicknamed “Mary Anning 2” was left unused.) NASA/JPL-Caltech/MSSS A very old search. Science has been obsessed with the search for life on Mars since in the 17th century some scientists detected with their telescopes what appeared to be the presence of water ice. Already in the 21st century, advances in space exploration allowed orbiters and rovers to be sent to Mars in order to analyze possible signs of life. Some were found. For example, in 2018 methane was detected in its atmosphere. This could be the result of microbial activity, but also geological processes. In 2020 Curiosity found carbon isotopes and later, in 2025, the longest carbon chain found to date. It is true that carbon is necessary for life, but it can also be related to many abiotic processes. In none of these cases has it been possible to demonstrate that there is life behind it, so we still cannot prove that there is life on Mars. Maybe we lack tools. In 2023 a study was carried out in the Atacama Desert to analyze the tools normally used to search for life on Mars. This desert is one of the largest Martian analogues we have on Earth. It has many similar characteristics to those of the red planet; but, of course, it also has more than proven life. However, when analyzed with Mars exploration tools, many of the traces of life that should have appeared were not detected. This shows that perhaps we haven’t found life on Mars yet because we don’t have the right tools. Although there may also simply not be any. The future. Curiosity has carried out this experiment directly on Mars. However, the ideal would be to send rock samples to Earth, to use other more complex analysis technologies there. Another rover, Perseverance, is prepared to collect samples and send them to Earth. In fact, it was scheduled to do so. However, the mission was canceled by the United States Congress last January. Meanwhile, other space agencies aim to replicate the TMAH experiments. This is the case of the ExoMars mission of the European Space Agencywhose Rosalind Franklin rover will also travel with this reagent to carry out thermochemolysis. We’ll have to wait to see what he discovers. Whatever it is, as always, we will read it with caution. Image | POT In Xataka | ExoMars, this is Europe’s most ambitious mission to Mars

Stress was designed by evolution to save your life. Modern chronic stress is taking it away from you

by

It is easy to hear in this society the phrase “I am very stressed” because we have more and more demands on us in the workplace or staffand the truth is that it is something that is gradually being used as a “crutch” to associate it with mental fatigue or lack of time. However, the reality is that the great effect that stress has on our body is generating very relevant physical problems that can alter us in the long term. Its effect. The immune system is a fundamental part of our body that defends us against microorganisms, but also against cells that do not follow a natural division and that, without this control, can continue ahead. generating cancer. That is why taking care of it is fundamentaland constant stress is one of your worst enemies by reducing your ability to act. There is no need to demonize. To understand the damage, we must first be fair with the stress, since logically there are situations where you have to have stress to be able to stay aliveand without that ‘stress’ our species would literally be extinct a long time ago. And to understand it, if we ‘travel’ thousands of years ago, if a lion chased a human, the body released adrenaline and cortisol, preparing the immune system for possible injuries and enhancing short-term defenses. The problem with modern life is that the “lion” is no longer a specific predator, but the mortgage, work or constant anxiety. But it is a problem. When stress becomes chronic, it becomes a poison for the body, since, according to different articles, the perpetual state of alert overstimulates the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. Here the result is a sustained elevation of cortisol that, paradoxically, ends up causing “glucocorticoid resistance,” which are the molecules that are naturally produced to reduce inflammation. The body is then flooded with stress hormones, but your cells stop responding properly to them to curb inflammation. And as we have seen on many occasions, long-term inflammation brings more problems than benefits. The defenses. The immune dysfunction caused by this chronic condition is perfectly documented. An example is in the classic Cohen study which already mapped out the physiological mechanisms that make us more vulnerable to infections, but experimental studies and reviews from 2025 give us an exact cellular x-ray of what we lose. Among the examples that stand out, we have a drastic reduction of NK cells which are our first line of defense against viruses and tumor cells. Furthermore, both T lymphocytes (which are fundamental cells of the immune system) such as B lymphocytes see their response capacity diminished, making them unable to ‘destroy’ microorganisms that enter our body. But if that were not enough, chronic stress ages the immune system before its time. In a loop. Perhaps the most fascinating discovery that science points to is the connection between the immune system and mental health through neuroinflammation. Here, chronic stress is literally wearing down the body by continually adapting, causing the immune system to skyrocket. proteins related to inflammation that can travel to the brain and activate microglia, which is the ‘defense’ system of the nervous system. The result? A neuroinflammatory environment that is directly linked to the development of depression and anxiety disorders. And logically, if we have anxiety, stress will continue to increase, causing more inflammatory proteins to be released that will continue to affect the brain. It’s not forever. Here science points out that the damage caused by stress is not perpetual, but can be reversed at any time through interventions psychological interventions focused on stress reduction, as well as regular physical exercise. This has shown that chronic inflammation can be reduced and normal immune system cell function restored. That is why now rest and mental health should not be seen as a luxury, but rather we must begin to see them as an important biological shield that can greatly extend our lives if we manage to keep it under control.

LaLiga’s massive IP blocks are making life impossible for users, companies and developers. So you can claim

by

LittleCranky67, which is the alias of our protagonist, didn’t know what was happening with his computer this weekend. This developer was doing something that never gave him any trouble: working with the GitLab platform to download a Docker software package. That process kept giving him strange errors, and LittleCranky67 ended up realizing what had caused it all: LaLiga’s indiscriminate IP blocking. After share your frustration on HackerNewshundreds of comments confirmed other similar cases, and in them we also discovered something interesting: how to officially claim LaLiga. Or at least, how to try. A sad old story. LaLiga he shields himself in the Judgment of December 18, 2024 issued by the Commercial Court No. 6 of Barcelona. This allows you to demand from operators such as Movistar, Vodafone, Orange or Digi to block at the IP level any address that is identified as a source of illegal IPTV broadcasts during LaLiga football matches. Many of those IPs are Cloudflare shared IPs, so when the IPTV service IP is blocked, all domains associated with that shared IP are blocked, which can be hundreds or even thousands. And in those domains there are web pages of private usersfrom companies that they stop being able to sell and also critical services for developers such as Docker, GitHub or GitLab. The irony is that lockdowns don’t work. While many users complain about these blocks and how are affecting websites and services that usemany others continue to remember on social networks that in reality the blocks to view these IPTV broadcasts can be easily circumvented in many ways. The most popular, use VPN services. In LaLiga they know that this method is widely used, so for months They are also working on blocking those services. It doesn’t seem to be serving a lotand whoever really wants to watch the football game without paying has many relatively simple ways to achieve it. If you are affected, you can claim. In that thread, several users remember that one way to try to change things is for users to protest, complain and complain en masse. There are several ways to do it: Telecommunications User Service Office. It is the official body in Spain for these cases. A formal claim can be filed for arbitrary loss of service or censorship, and even claim financial losses if the blockade prevents you from working. Those who have a digital certificate or Cl@ve can do so directly online. Complain to your internet provider. It is also important to open a support ticket with your operator. It is true that they are obliged to follow court orders, but they must know that the blockade is causing collateral damage to services that have nothing to do with football. Common Electronic Registry (SARA network). This portal It also allows you to send formal complaints to management if other methods fail. Spanish Data Protection Agency (AEPD). Those responsible for RootedCON have been fighting this situation for some time, and offer another recommendation: report LaLiga to the AEPD. This template allows you to complete that complaint in a simple way Demagive to Telecommunications Operators. At RootedCON they also suggest filing a complaint against ISPs, and explain the process in a small thread on Twitter. Again, just download a request and file it individually. Complaint to the European Commission. It is also possible to enter the European Commission complaints website to send a claim to the entity. We explained it in Xataka and the process is another way of trying to stop this situation with the help of European bodies. The BOE serves as a defensive argument. In these complaints it is advisable to cite the BOE-A-2022-10757 as a legal reference. It corresponds to Law 11/2022, of June 28, General Telecommunications (LGTel) and is the fundamental rule that regulates your rights as an internet user in Spain. The message that we can write is the following: “Under the protection of Law 11/2022, of June 28, General Telecommunications (BOE-A-2022-10757), specifically regarding the rights of end users (Chapter IV) and the principles of continuity and quality of service, I present this claim for the blocking of access to legitimate IP addresses (specify which ones, e.g. Cloudflare/Docker) unrelated to any illicit activity. This blockade constitutes a violation of my right to communication and the contracted service, causing harm (professional/personal) by preventing the operation of work/security tools. “I request the immediate cessation of said technical restriction in compliance with the provisions of the aforementioned Law.” The nightmare continues. The debate in HackerNews is nothing more than confirmation of what internet users in Spain have been suffering for more than a year. A private organization has the power to order ISPs in a country to indiscriminately block IPs without judicial review in real time, during regular hours, causing documented harm to third parties that have nothing to do with the original violation. In that thread some users compare the situation with that of the Great Firewall of Chinanot so much in intensity as in its logic. We are faced with an infrastructure of selective censorship that seems to be able to be applied to any content that an actor with sufficient judicial power wants to block. From football to tennis or golf. In fact, things could go further, because what began as an attack against illegal broadcasts of football matches could now be seen in other sports such as tennis or golf. Telefónica —which follows in the footsteps of LaLiga— wants to extend indiscriminate blockades to the Champions League, tennis or golf. This threatens to suffer these side effects for many more days and for many more hours, and can mean that for a good part of the week, users like LittleCranky67 find themselves unable to download Docker packages or access thousands of legitimate websites that end up being knocked down by these blocks.

This engineer found 1,351 loose photos in his grandmother’s house. He ended up building a personal Wikipedia of his entire life

by

It all started with a closet full of old loose photos. Last year an engineer named Jeremy visited his grandmother’s house for the first time since the pandemic and unknowingly came across a treasure. 1,351 on paper, without order, without dates and without context. Some were in black and white, from when his grandparents were 20 years old. Others were from his mother as a baby. The last ones were from him in high school, just before smartphones arrived and everything moved to the cloud. What began as a family organization exercise became a fascinating project over the weeks: a personal encyclopedia. A Wikipedia of his own life. First, the physical photos and the grandmother. The first problem he encountered when starting his project is that physical photos do not have EXIF metadata. There is almost never a capture date (although some cameras superimposed it), there are no GPS coordinates and there is no information that allows them to be easily sorted. What Jeremy did was resort to a much more direct solution: sit down with his grandmother and ask her about the photos. Remembering that it is a gerund. In that conversation she rearranged the photos of their wedding and narrated the details while he took notes. Names, places, who was sitting where, what each ritual meant. With those notes, he set up a local instance of MediaWiki, the same software that Wikipedia uses, and wrote a page about the wedding following the same format that was used on Wikipedia to royal wedding between Prince William and Kate Middleton in 2011. Within two afternoons I had a complete article with scanned photos, captions, links to empty pages about each person mentioned, and links to the real Wikipedia to give historical context to the events. Digital photos and Claude Code to get the job done. Jeremy realized that things could get worse and took the opportunity to do tests with digital photos, which do have EXIF data with date and time and even GPS coordinates. With that information he wanted to see how far he could go without interviews, so he took 625 photos from a family trip to Coorg (India) in 2012, put them in a folder and opened Claude Code in that directory with a simple instruction: compose a Wikipedia page by browsing the images. The model used ImageMagick to create contact sheets that allowed him to process multiple photos at once, and the magic of AI did the rest. The result was a detailed draft chronicling the trip organized by time of day. Without location data, just with timestamps and visual content, the AI ​​model was able to identify the places that appeared in the photos, including some that Jeremy himself had forgotten. It even detected the means of transportation used between destinations just with what it saw in the images. When AI starts remembering for you. Then came the most ambitious experiment, when he wanted to go further with a trip he took to Mexico City in 2022. He had 291 photos and 343 videos taken with an iPhone 12 Pro with GPS coordinates in the metadata, but he also exported his Google Maps location history, his Uber trips, his banking transactions and his Shazam history. By including all that data and sources, the model was able to cross-reference banking transactions with location data to identify the restaurants where he had eaten. For example, he found images of a soccer match in the photos but did not remember which teams were playing, but he found out that information by crossing those photos with bank transactions in which he found a Ticketmaster invoice with the name of the tournament and the teams, and incorporated them into the page. He also used Shazam’s history to describe the music playing in each location. From photos and memories to a personal encyclopedia. A wonderful project that now anyone can replicate thanks to the whoami.wiki website. First the trips, then the friendships. What started as a travel documentation project evolved into something more personal. The Facebook, Instagram and WhatsApp archives contained some 100,000 messages and several thousand voice notes exchanged with close friends over a decade. The AI ​​model managed to convert all this information into a unique biography, identifying vital episodes of the protagonists, then converted into pages that, according to Jeremy, “read as if they were written by someone who knew us both.” When he shared the pages with those friends, they couldn’t stop reading those stories and wanted more. MediaWiki as a master ingredient. One of the most interesting decisions of the project is the choice of software. MediaWiki, Wikipedia’s engine, turned out to be an extraordinarily suitable tool for that use case. AI models understand this perfectly because they have been trained with millions of Wikipedia pages and know their structure and functioning. Discussion pages serve to control the development of those pages, categories group pages by topic, and revision history monitors the evolution of each page. All of this infrastructure already existed, and it was not necessary to create a new platform to organize the information that Jeremy was providing. Surpriseyes. At the end of his story, Jeremy explains that after the process: “I realized that I was no longer alone working on a family history project. What I had been creating, page by page, was a personal encyclopedia. A structured, navigable, interconnected record of my life compiled thanks to the data I already had around me.” Documenting her grandmother’s life revealed things she didn’t know: her years as a single mother or the decisions she had to make, for example. Going through the history of his friendships allowed him to recover moments that he had almost forgotten and made him call some of them to remember them together. “The encyclopedia not only organized the data, it made me pay more attention to the people in my life,” he explained. you can do it too. The project has been so rewarding for him that he … Read more

“Nothing in life is to be feared, only understood”

by

If I knew anything Maria Salomea Skłodowska (Marie Curie), even more than Physics or Chemistry, two disciplines in which she won two Nobel Prizes, is one of uncertainty. And how to face it. Curie was not only a pioneer in the field of radioactivity (at that time full of unknowns) and discoverer, together with her husband, Pierre, of the chemical elements polonium and radium. He also had to live a world war and make their way in a territory dominated by men, something that makes clear the very famous photo of the fifth Solvay Congress, in 1927, in which she poses as the only woman among almost thirty men. That is why almost a century later his reflections on how to confront fear, uncertainty and their multiple causes are a crucial part of his legacy. Curie’s example. We were talking about it not long ago: the history of philosophy is full of round phrases of uncertain origin. There are plenty of them, even reflections attributed to two authors at the same time, such as it’s about procrastination that some sources put in mouth by Leonardo Da Vinci and others of the 18th century French moralist Joseph Joubert. The Marie Curie phrase that concerns us today and with which we head this post is also of confusing origin. Some historians have traced its origins until 1952 and the truth is that since the 60s it has been replicated in countless essays, books and articles, which makes it one of the most popular phrases attributed to Curie. Does it make sense? A lot. Basically because, unlike what happens with other famous proverbs of uncertain origin that clash diametrically with the thoughts of the authors to whom it is attributed, this one in question summarizes Curie’s life. What does the phrase say? The sentence It’s simple. Rotunda. With an almost magnetic force. And above all it is loaded with meanings. “Nothing in life should be feared, only understood. When you understand, fear disappears.” In those two sentences Marie Curie addresses several questions that philosophy has been asking for centuries, issues that date back long before the time of the Polish scientist and still continue to obsess us today: What exactly is fear? What produces it? Is it good or bad? How should we act before him? What is the best way to approach it to avoid it paralyzing or limiting us? From the outset, what Marie Curie tells us is that we should not deny fear. On the contrary. That something makes us afraid, especially if it is new to us, is totally understandable. The key is how we react to that sensation. Our attitude, the Polish scientist encourages usit must be rational, not visceral. If we really want to face fear and escape its radius of action, we will have to stop and try to understand what scares us. More than words. That this phrase has been captivating us for more than half a century has nothing mysterious. To a large extent it is explained by two factors: what it says and above all who says it. Regarding the first, time has proven Marie Curie right. Today psychologists recognize that fear is not a negative emotion in itself, it is part of our most basic toolbox to survive. In fact it is a natural reaction to the unknown. If something is disconcerting to us, it is not strange that it frightens us. It’s that simple. The problem is that this feeling ends up being disabling or leads to rejection. If that happens we run the risk of closing doors. As they explain our colleagues Trendsmany times we find it difficult to move forward or we feel limited not because we encounter an objectively high risk, but simply because we do not take the time to understand it. That’s when Curie’s voice resonates: “When you understand, fear disappears.” Setting an example. The other reason why the phrase has been fascinating us for decades is because in a way it summarizes the vital and intellectual position of the scientist. If there was one thing Curie explored throughout her life, it was the new, and if there was one thing she had to manage, it was uncertainty (and probably the fears that accompanied it). First because he had to deal with a turbulent historical moment. Marie was born in a Poland controlled by the Russian Empire, experienced hardships in Paris during her early years of training and, as an adult, faced a world war, the premature death of her husband and the misunderstanding from his colleagues. If the above were not enough, Curie strove to expand the horizons of science, facing precisely the new: together with her husband she discovered two chemical elements, radium and polonium, and was a pioneer of radioactivity, which she soon actively took advantage of to help wounded soldiers. All this in an academic sphere basically dominated by men. Current in the 21st century. Curie’s words also have a scope that goes from the individual to the collective. His advice on how to approach fears and the value of understanding to scare them away serves as a personal guide, but also makes for interesting reading in a world increasingly polarized. “When you understand, fear disappears,” insists Marie Curie. That of course has its toll: understanding requires effort, leaving the comfort zone, giving up the most visceral responses and exercising reason.

We have found a time capsule in the form of salt in Chile. And now finding life on Mars is closer

by

As we continue to explore how to get to Mars with Artemis II As a critical engineering and logistics bridge in the form of a long-term trial of interplanetary travel, science continues to search for traces of life on the red planet. And it is not easy: although 3.37 billion years ago an ocean covered half the planetMars is today a dry planet devastated by radiation. The question is where to look for that life. The answer, as incredible as it may seem, may be more than 3,500 meters high in the north of Chile, in the Salar de Pajonales, a landscape that is also desolate where there is a range of extreme temperatures ranging between -23 °C and 26 °C, one of the highest solar radiation recorded on Earth, there is hardly any precipitation and winds that exceed 100 km/h. And yet, there is life. There a research team has discovered that plaster constitutes the perfect refuge for life. Spoiler: Gypsum is a common mineral both on Earth like on mars. The discovery. According to this research, gypsum is not only a sedimentary rock, but also a biological repository. Thus, this mineral is capable of harboring both current life in the form of microorganisms that live within the crystals and preserving molecular fossils and microscopic structures. A kind of time capsule that protects organic material from degradation for millions of years. Why is it important. The consequence of this finding in space research is direct: if gypsum is a “magnet” for biological preservation in hyperaridity conditions, the scientific community knows that the abundant sulfate deposits on Mars (such as Gale crater) are a magnificent place to continue searching for traces of extraterrestrial life. If there was life on Mars, gypsum is a likely place to house its traces. Context. The Salar de Pajonales seems like a place from another planet: it is in high mountains where ultraviolet radiation is high, there is extreme aridity and thermal fluctuations reminiscent of the conditions on Mars from billions of years ago, when the red planet began to dry out. In this scenario, life has learned to hide from the unfriendly surface in a lifestyle endolithic to survive. Thus, the mineral functions as a solar shield and moisture reserve. How have they done it. To read what the rocks contain, the Tebes-Cayo team has applied a kind of high-precision molecular and mineral archaeology: With habitability and climate analysis with a meteorological station that recorded data every 20 minutes for 40 years monitoring water activity. Using x-rays, petrography and microfluorescence to create thin sections to distinguish minerals and their distribution without destroying the sample. With microscope, isotopes and DNA sequencing to identify the microorganisms, the trapped corpses and to confirm that the carbon found has a biological and not a geological origin. Yesyes, but. We already know that gypsum is the ideal candidate to search for life on Mars, but that is based on a hypothetical premise: that it ever existed. On the other hand, and although the Salar de Pajonales is reminiscent of the Red Planet, the conditions on Mars are even more extreme than in Chile (there is almost no atmosphere and it is even colder), which may have affected the preservation in a different way. And then there is the practical application: it is one thing to detect these biosignatures in the high mountains of Chile and another to use a robot thousands of kilometers away for the same purpose.

Extend the life of your dinosaur carrier

by

To give us an idea, a nuclear aircraft carrier It can operate for more than 20 years without refueling and mobilize thousands of people, including crew and air wing. Each of these ships, or floating mini-cities, acts as a total military base capable of intervening anywhere on the planet in a matter of days. The problem is that they also have an expiration date. A decision that was not in the plans. The announced and unusual USS Nimitz aircraft carrier extension until 2027 does not seem to respond to a planned improvement or a long-term strategic update of the United States, but rather to a correction on the fly derived from the turbulent times and current war conflicts. We are talking about the oldest aircraft carrier in Washington’s fleet, it had to start his withdrawal much earlierbut that the Navy has chosen to keep it active to cover a gap that cannot be filled with other means. It is a very unusual decision because it prolongs the life of a ship that has already far exceeded its planned operating cycle, indicating that the original planning has been exceeded. due to the current situation. The requirement: 11. Behind it there is an idea that no one has wanted to knock down. The United States is required by law to maintain at least eleven aircraft carriers in servicebut meeting that number has become increasingly complicated. The removal of a ship of these characteristics without having its replacement ready generates an immediate deficit that affects the entire operational structure. In this case, the Nimitz is kept in service not because it is essential for its own sake, but because it is necessary to maintain that legal minimum and avoid a drop in global deployment capacity. Nimitz flight deck A delay and the consequences. Plus: the problem is aggravated because the aircraft carrier that was to replace it, the USS John F. Kennedyit will not be ready until, at least, the year 2027. This industrial delay forces us to extend the life of old systems to maintain operational continuity. In a fleet where each unit requires years of construction and planning, any slippage in the schedule has direct and long-lasting effects. The Nimitz thus becomes a temporary solution to cover this gap, but also a symptom that the renewal of the fleet is not following the expected pace. Subjected to intensive use. At the same time, aircraft carriers in service are operating under pressure extremely high. Deployments that should last between six and eight months are becoming longer, affecting both the condition of the ships and the crews. Already we tell it these days. The case of the USS Gerald R. Ford is possibly the most illustrative: after months of deployment and accumulated problems, a fire has forced him to temporarily withdraw from the operation in the Middle East. Thus, each incident or delay further reduces global availability and forces the remaining resources to be redeployed. Chain effect. Additionally, when aircraft carriers remain deployed longer than expected, maintenance it delays and accumulates. This not only affects the vessel in question, but the entire fleet planning, since shipyards, crews and repair cycles are designed years in advance. The result is a domino chain effect in which each extension or breakdown complicates the next rotationreducing operational flexibility and increasing overall wear and tear. The context: a constant presence. All this occurs at a time when the demand for aircraft carriers is especially high. The war in the east Middle and tensions in Asia They require a sustained naval presence in multiple regions at the same time. Thus, while aircraft carriers remain the United States’ main power projection tool, their number and availability do nothing more than the ability to cover all scenarios simultaneously, because when one is out of service, the impact is immediately noticeable. Nimitz and the problem. Ultimately, the decision of keep active to the aircraft carrier USS Nimitz is not exactly a sign of strength, but rather of adjustment to a situation increasingly demanding. Indicates that the Navy is using all available resources to sustain your level of presence globally, even those models that were destined to be retired. Worse still, in practical terms, it reflects a fleet that, although still capable of operating in multiple scenarios, does so with less margin of reserve and greater dependence on exceptional decisions to maintain balance. And where a fire in a laundry or a problem in the toilets can be the same incendiary than a ballistic missile.

“Life begins on the other side of despair”

by

It doesn’t matter where you are from, how old you are, what you do or what you entertain yourself with. It almost doesn’t matter how you think. Most likely the word “despair” causes you an automatic rejection. Normal, right? In life there are good sensations, others that are debatable, and there are those that are undesirable no matter how you look at them. Despair, anguish, is part of the latter because no one in their right mind would choose despair over hope. No? If we are clear about the above, why the hell in 1943 did the philosopher Jean-Paul Sartreone of the most prestigious minds of the 20th century, had Orestes pronounce the next words in his theater work The flies? “Human life begins on the other side of despair.” The question is timely because, unlike what happens in most literary works, here it does not seem that it is the character who speaks to us. If we take into account Sartre’s philosophy, in this case it is not unreasonable to think that it’s himself who moves Orestes’ lips to express his opinion. Did Sartre really believe that ‘despair’ is the door to life? Isn’t that a discouraging and gloomy panorama? Sartre and existentialism Before talking about how Sartre thought, it is worth knowing who Sartre was, one of the lighthouses of Western philosophy of the 20th century. Thinker, novelist, playwright, critic and political activist, Jean-Paul Sartre (1905-1980) is remembered above all for being one of the great exponents of existentialism. Without it it is difficult to understand the intellectual panorama of 20th century Europe and figures of the stature of Soren Kierkegaard, Lev Chestov, Albert Camus either Martin Heidegger. Although its seams are wide and there are important differences between authors, basically existentialism as conceived by Sartre (atheistic existentialism) is based on a premise: humans are born without a predefined purpose. We are not toasters, cars or TVs, objects created based on a concept and with a specific purpose. Nor are we the work of a superior “craftsman.” Unlike what happens with what we make as men, objects in which the “essence” is prior to the “existence”, in our case it is the existence that precedes the essence. What does that mean? “That man begins by existing, finds himself, emerges in the world, and then defines himself,” the French thinker clarifies in one of his key works, Existentialism is a humanism. “Man, as the existentialist conceives him, if he is not definable, it is because he begins by being nothing. He will only be later, and he will be as he has been made. Thus, then, there is no human nature, because there is no God to conceive it,” Sartre continuesand insists: “Man is nothing other than what he makes himself”, a creature “condemned to be free.” We have not chosen to be here. We have not created ourselves. And yet we are responsible for everything we do. It is not lost on Sartre that this scenario can lead to “anguish”, a feeling of helplessness and despair. He is not the only philosopher who addresses the topic (Heidegger and Kierkegaard also did), although it is true that the Frenchman’s work helps us understand how important sensation is. for him Anguish is nothing other than “the awareness of being one’s own future in the way of not being one”, an overwhelming feeling in the face of the range of possibilities that are open to man, radical freedom and lack of answers. This approach leaves behind an idea that is as fascinating as it is overwhelming: man is born with a huge challenge aheadthe challenge of living authentically, assuming your freedom, choosing your course, giving meaning to yourself and making decisions that will have consequences for your entire environment. There is no destination. There are no excuses. It depends on us. “Man will only be afterwards and will be as he has been made. It is nothing other than what he makes himself. If it precedes the essence, man is responsible for what he is”, warns us. “(Fyodor) Dostoyevsky writes: ‘If God did not exist, everything would be permitted.’ This is the starting point of existentialism. In fact, everything is permitted if God does not exist and, consequently, man is abandoned, because he finds neither in himself nor outside himself a possibility of clinging. “First of all, it finds no excuses. If existence precedes essence, the reference to a given and fixed human nature can never be explained. In other words, there is no determinism, man is free, freedom.” “The first step of existentialism is to put every man in possession of what he is and to place upon him the total responsibility for his existence. And when we say that man is responsible for himself, we do not mean that man is responsible for his strict individuality, but that he is responsible for all men,” Sartre continues. Understanding this enormous responsibility and all its implications generates anxiety, but that has no why be negative. The reason? As Orestes proclaims in his dialogue of the The flies This hopelessness does not have to be frustrating or plunge us into inaction. On the contrary. “It is the very condition of their action because this means that they face a plurality of possibilities and, when they choose one, they realize that it only has value because it has been chosen,” illustrates the philosopher, drawing a parallel with the anguish that a general feels when he decides something that will affect the lives of his soldiers. “existentialism is an optimism, a doctrine of action,” claims Sartre, who ends his essay with a warning: those who use despair to attack it do so by “confusing their own feeling with ours.” It may sound like an old-fashioned lesson (Sartre died in 1980), but his words resonate strongly in an era in which we live hyperconnected, among related ephemera in which the need to search for meaning, identity and authenticity is especially felt.
