culprit

For years we blamed testosterone for men living shorter lives. Now we know that the culprit is a chromosome

by

For decades, biology has observed an incontestable demographic fact: women live longer than men. It has often been blamed lifestyleto testosterone or to the greater male propensity for risky activities. However, science has found a much more subtle and genetic culprit that we carry in all our cells and that literally we start to lose as we get older. A genetics class. In a very general way, we must remember that all our genetic information is collected in 46 chromosomes which are found within the nuclei of our cells in pairs. But there is a part of all these chromosomes that define us as men or women: The presence of two X chromosomes defines women and the presence of one X chromosome with one Y defines men. Although there is great genetic complexity behind something as redundant as a pair of chromosomes, what interests us in this case is that science has seen a effect called mLOYwhich is literally the loss of Y chromosome mosaic in men. And different scientific articles suggest that it is not a simple side effect of getting older, but rather it is a “silent killer” that explains much of the longevity gap between the sexes. The runaway chromosome. For a long time, the Y chromosome was considered the “little brother” of the genome. Small, with few genes and almost exclusively responsible for determining the male sex with no other known functions, almost all of which fall on the X chromosome of considerable size. But the truth is that we were wrong, and the Y chromosome has great importance in the adult life of men. The mLOY phenomenon. This occurs when the cells that are in charge of manufacturing the blood elementslike erythrocytes, platelets, or lymphocytes, suffer errors when dividing and lose the Y chromosome. Something that generates a “mosaic” in our body, that is, some white blood cells have the Y chromosome while others do not. But what is disturbing is the frequency with which it occurs, since, according to the data reviewed, this is something that has been detected in 40% of men at age 60 and in 70% of men at age 90. There is damage. Until recently, it was believed that losing this chromosome was benign and normal, a simple “genetic gray hair.” But the evidence accumulated between 2022 and 2025, including massive UK Biobank studies and the recent German studio LURIChas set off alarm bells: losing the Y chromosome is not harmless and has important side effects. The heart. One of these side effects is precisely heart failure, which is a very prevalent disease in the elderly. Here science has been able to see that, by eliminating the Y chromosome in mice, the animals rapidly developed cardiac fibrosis. That is, their hearts were filled with scar tissue, becoming rigid and, therefore, having great difficulty pumping blood. But it is not the only disease that occurs, since in the United Kingdom Biobank, men with mLOY in more than 40% of their white blood cells had a 31% higher risk of dying from cardiovascular causes. And even the LURIC study published last year, carried out on 1,700 men, found that the mLOY effect increased the risk of fatal heart attack by almost 50%. More diseases. Beyond the heart, the impact of losing the Y chromosome also affects our body’s defense system to be able to combat different threats. Among them we have cancer, since the immune system needs the Y chromosome to effectively monitor the tumor cells that arise. Its loss is associated with a worse prognosis in bladder cancer and other solid tumors, since it is as if our body’s security guards had gone partially blind. In addition to cancer, the frequency of mLOY has also been seen to be up to 10 times higher in patients who have Alzheimer’swith studies showing an almost 3 times higher risk of developing the disease. The COVID. During the pandemic we saw that older men died much more than women without fully understanding why. We now know that the loss of the Y chromosome increases 54% risk of fatality for being infected with COVID in the elderly, finally offering a biological explanation for this bias. Is there a solution? It may seem depressing to know that a part of our DNA decides to abandon us and cause us so many problems, but in reality, it is a hopeful finding. And it is hopeful, since, seeing that the loss of the Y chromosome is a direct cause of a disease, therapeutic doors open. In experiments with mice, it has been seen that treatment with an antifibrotic drug was able to reverse the cardiac damage caused by the loss of the chromosome. This means that the mLOY effect can be used as a marker in a blood test, as happens with cholesterol, to predict a patient’s cardiac risk and to be able to give preventive treatments to delay it and improve the patient’s quality of life.

The number of new apps coming to the App Store has skyrocketed. We have a culprit: “vibe coding”

by

The arrival of tools based on generative artificial intelligence has caused a real explosion in mobile application stores, especially since we have development environments with AI that allow us to create and deploy applications without needing to know programming. According to data from venture capital fund Andreessen Horowitz (a16z), new apps launched in the iOS App Store in the United States increased 60% year-on-year in December, after remaining practically stagnant for the previous three years. The accumulated year-on-year growth in the last twelve months reaches 24%. The person responsible has a name: the “vibe coding“, that way of programming in which AI does much of the work. What is happening. 2025 has been the year in which “sensation programming” has exploded. And it is that in environments of ‘agentic programming‘ or vibe coding, just explain to an AI tool what application you need and the machine takes care of writing the code. Platforms like CursorBolt, Google AI StudioClaude Code or V0 have democratized app creation to the point that anyone with an idea can turn it into a working prototype without writing a single line of code. This opens many doors, as thousands of new developers without technical training are publishing applications in stores. That’s also a problem. Going back to 2008. As points out a16z, the situation evokes the early days of the iPhonewhen Apple launched its SDK and in a matter of months went from 500 applications to downloads that exceeded 1,000 million. That ecosystem ended up generating hundreds of billions of dollars in revenue. Here the phenomenon is even more overwhelming, since the creation of applications is no longer ‘limited’ to experienced developers, which means that in an afternoon we can create any simple app, as long as we know what to ask of the AI. Image: a16z The problem. Things are clear: you will not be able to create a complex application in one sentence. And now he told us Miguel Ángel Durán, a software engineer known as midudev, in March of last year: “don’t think that just saying something without knowing anything about programming is going to give you the next Airbnb.” As my colleague Javier Pastor mentioned some time ago, the case of Leoa user who created an entire SaaS platform with vibe coding and even got paying customers, perfectly illustrates the risks, since two days after bragging about his achievement, he had to ask for help because his app displayed public API keys, had an easy-to-jump paywall, and crashed his database due to basic programming errors. Quality matters. “You can do very basic things. We have tried Cursor, Bolt, etc., and you reach a level that one may think is advanced, but in reality what usually happens is that they are cloning a Github repository and changing its colors,” we say. counted Some time ago Daniel Ávila, co-founder of CodeGPT. There is a flood of low-quality apps, much more than before, since now many more inexperienced people can easily publish them in any app store. And the problem is that many of these applications do not even reach the prototype level, being unfinished products that work superficially and then end up accumulating all kinds of technical errors. Even worse if the app has a paywall. Between optimism and caution. “Vibe coding is super interesting to extend the prototyping of ideas and empower people,” we say. explained last year Nerea Luis, doctor in computer science. But he also recognizes that “it has risks” because completing these projects requires knowledge that neither the user nor the AI ​​possess. On the other hand, Omar Pera, Chief Product Officer of Freepik, was more optimistic: “vibe coding turns top engineers into 2x or 3x engineers.” Does it democratize access to application development? Yes, of course. The problem comes when the AI-generated application of someone without experience goes from a project to learn, as a hobby, or as an app development for one’s own use, to a project that encompasses more ambition and seeks to attract many clients.

110 years later we finally know what sank the ‘endurance’ in the Antarctic. The culprit was not the ice: it was much worse

by

He Endurancethe legendary ship of Ernest Shackletonbecame a symbol of resistance and heroism after its sinking in the icy waters of the Weddell Sea in 1915. There began the myth, because during more than a centuryits end was wrapped in a halo of mystery, attributed to the lethal coup of the ice against its rudder. Now, science He has revealed That the truth was more complex and, in a way, disturbing: the ship was never prepared to survive. The myth and the truth. As we said, for more than a century, 110 years to be exact, Ernest Shackleton’s heroic story and his antarctic ice crew was accompanied by the conviction that the endurance was the wooden ship more robust of his timevictim of a fatal blow of the ice against his helm. However, Recent research They have dismantled that narrative. The thorough analysis of the wreck discovered in 2022 reveals that the ship I was convicted From the beginning: it was not a single impact that sank it, but the accumulation of compressive forces that crushed their weak structure and, very important in the final story, Shackleton I probably knew When he left for Weddell. The expedition trapped. Endurance sailed in 1914 with the ambitious plan of cross the Antarctica on footbut at the beginning of 1915 he was caught in a solid ice. For ten months the crew resisted on board until the pressures began to deform the ship. The covers were combined, the helmet vibrated with a crash and the newspapers of the sailors picked up the sound of the creak of the wood under huge forces. On October 27, 1915 Shackleton ordered to leave the shipand weeks later the helmet ended up sinking after a succession of pressure onslaught that started masts and opened the structure in two. Idealized cross sections of the first Antarctic ships. The endurance was of the type (a); The type Deutschland (B) Fortress with mud feet. Far from being the invulnerable ship of the legend, the endurance was born as a ship of Polar and Hunting Tourism of bears and morsas in the Arctic. Its design lacked the critical reinforcements to survive trapped in an icy sea: it had no diagonal beams that kept the bands of the helmet or racks that supported the machine room, its most fragile area. Over there, According to witnesses As the scientist Reginald James or Captain Frank Worsley, the iron plates combined and the soils bulging while the ice pressed incessantly. The Rudder and the keel departed, but they were not the cause but the consequence of that structural weakness. Pecio discovered in 2022 Shackleton knew it. It is one of the keys that light has seen now. The most revealing thing is that Shackleton I did not ignore Those defects. He had participated in rescues from other ships shattered by ice and advised the German Wilhelm Filchner reinforce with diagonal beams Your Deutschlandthat thus managed to survive eight months trapped. Even in a letter to his wife he admitted that the endurance was not as solid as The Nimrodthe ship of your previous expedition. Even so, He acquired it Without modifications, moved by the urgency of undertaking a colossal project in the midst of their debts, their personal failures and competition with other explorers for reaching Antarctic glory. The re -written history. He New study of Jukka Tuhkuri Disassemble the myth of the invulnerability of the endurance, showing that it was an inappropriate ship faced with a relentless environment. However, this finding does not decrease the figure of Shackleton, but it frames it With more realism: A leader who risked aware that the adventure could cost the ship, but that miraculously saved his entire crew. At a time when polar exploration was a jump of faith towards the unknown, the wreck of the endurance was not only the end of a ship, but the proof that even the stronger wood yields Before ice pressurewhile human will manages to survive where the technique fails. Shared destination. The truth is that the Endurance drama It was not an isolated episode. Decades earlier, in 1876, twelve American whales They sank in front of Alaska for lacking the necessary reinforcements against compressed ice, dragging with him the livelihood of hundreds of families. Something similar happened in 1903 with The Antarctica Swedish ship trapped and shattered in the Weddell Sea. And, in contrast, the case of Deutschland It demonstrates how simple modifications could make the difference between sinking and survival. If you want also, all these episodes draw a pattern: polar ice does not forgive improvisations or risk economies. Shackleton, with his leadership instinct, achieved what other captains They did not achieve: save all his men, although at the expense of expose them to sacrifice of a ship that had never had to face the brutality of the white continent.

Spain, at the head in Europe in workers with stress or depression and we have the culprit: work

by

In recent years, Spain has established itself as one of the European countries where they relate more workers Mental health problems with employmentstanding among the five countries With higher stress ratesdepression and anxiety linked to the work context, according to the latest survey OSH click 2025 that elaborates the European Agency for Safety and Health at Work (EU-OSHA). The data places Spain among countries with worse indicators In psychological well -being work related, only surpassed by Greece, Finland, Cyprus and Poland. In Spain, work with too much stress. The survey reveals that 40% of Spanish employees interviewed by the European Agency for Labor Safety and Health, pointed to their job as main reason for stressanxiety or depression. This percentage of stressed employees leaves Spain only behind Greece (49%), Finland (45%), Cyprus and Poland (both with 41%) and well above the European average located at 29%. In addition to stress, employees point out Other symptoms and pathologies which also frequently relate to the workplace. 45% indicate generalized fatigue related to work, 42% report headaches or tired view and 37% identify muscle pains or bones caused by their work activity, figures equally higher than the average recorded by the EU. Companies look the other way. The European report links this increase in work stress to the low implementation of preventive measures by Spanish companies. While 44% of employees in the European Union claim to be exposed to time or Work overloadin Spain this figure amounts to 49%. In addition, Spain is one of the countries where you least consult the templates on psychosocial risks, standing at 34% of employees who affirm that the companies where they work take into account their indications on mental illnesses, compared to 45% of the European average, and far from countries with best practices such as Germany, where 65% of respondents affirm that in their companies they have been consulted. In Spain we are not very psychologist. An important point that highlights the survey is that, in Spain, the culture of Mental health assistance to social level, much less at work level. A good barometer of this is that the psychological advice in the work environment is still very limited in Spain, where only 28% of the people surveyed say they have this resource in their company, compared to 40% on average in the European Union. Finland is headed in this regard, reaching 78% of companies that offer mental health advice and assistance for their employees. This deficit in access to psychological support from the company itself contributes to enching the impact of mental health problems on the templates, as the report points out ‘WHO guidelines on mental health at work ‘ Posted by the World Health Organization (WHO). An obstacle to professional careers. As a consequence of the lack of culture of psychological well -being in Spain that the European report indicated, the belief that reveal a mental health problem It will involve a social and professional stigma that will negatively affect the development of the professional career. However, that feeling, although on different scale, is common to all EU countries. That fear of stigma makes 48% of European employees say that revealing that they suffer a mentally affecting a problem of their professional career. In Spain, this percentage rises to 54%. The study indicates that this fear is especially high among younger employees or those who occupy precarious jobs, still increasing their vulnerability in the labor market. More stress, lower medical. According to the AXA 2025 Mental Health Studythe disabilities related to mental health problems have climbed into among the diseases with greater affectation since 2016 in the Spanish work environment. Taa and as stood out The countryPandemia marked a turning point In temporal disabilities due to psychological and psychiatric problems, with a 72% increase in casualties. This has put on the table the need for Review prevention strategies and support for mental health within companies, an aspect where Spain still shows important deficiencies regarding the European environment.

There are more and more older people dying for falls in the US. And the culprit is an old acquaintance in the West

by

We recently discovered that from the age of 35 our performance did not collapse as it had been thought, but rather On the contrary. However, it is a law of life that new problems derived from health and our physical form arrive with old age. In fact, in the United States they have realized one thing: more and more elderly die from falls, and have found the culprit. A growing problem. In the United States, falls have become one of the main causes of death among older people. In 2023 they died More than 41,000 adults over 65 years of injuries associated with fallsand the mortality rate has tripled in three decades. The most vulnerable group, those over 85, went from 92 deaths per 100,000 in 1990 A 339 in 2023. This increase is alarming because it coincides with decades of programs, medical guides and investments to prevent falls that, despite the efforts, have failed to reverse the trend. Drugs as a trigger. Epidemiologist Thomas Farley holds that differentiates it with countries like Japan or Europe lies in the high medication of the greatest Americans. Points to the called Frids (“Fall Risk Drugs”), a group that includes benzodiazepines, opioids, antidepressants, gabapentin, certain classic heart and antihistamine medications such as diphenhydramine. These drugs induce sleepiness, dizziness or weakness, and are linked to 50–75% more falls in the elderly. His proliferation, in his opinion, explains why deaths multiplied without other factors, such as loss of mobility, poor vision or risk risks, have worsened in the same proportion. Other factors. Other specialists like Thomas Gill and Neil Alexander Matizan In the New York Times That vision. They point out that before death certificates used to attribute the death of elders to heart failure or other ailments, minimizing the role of falls. Today Document betterwhich increases statistics. In addition, medicine prolongs the lives of people with chronic diseases and multiple disabilities, making the current cohort of over 85 years Be more fragile than that of thirty years ago. That accumulated fragility could partly explain why they survive less after a fall. Also, although the use of opioid and benzodiazepines has decreased or stabilized, they have The prescriptions are grown of antidepressants and gabapentin, which maintains the pharmacological exposure. The urgency of the “discomfort.” Before the consensus that drugs play a key role, the emerging strategy It is the “discomfort”: Review and remove unnecessary medication or adjust doses to reduce risks. Networks like the US depressal recordch network They insist that it is easy to prescribe, but difficult to remove treatments once established, by clinical inertia and patient resistance. The list Beers Criteria I already recommend alternative therapiesas cognitive-behavioral therapy for insomnia, physiotherapy, exercise and psychological approaches for pain, instead of powerful anxiolytic or analgesics. Samurai discipline to the rescue. In parallel to the numbers of the United States, Un work from the University of Tohoku revealed that The re-hoa traditional Japanese practice associated with the samurai that consists of slow and controlled movements of sitting, rising and walking, can significantly improve the strength of the knees and reduce the risk of falls in seniors. In just three months, adults who made this routine for five minutes a day, four times a week, increased on average 25.9% Its knee extension force, compared to 2.5% of the control group. The method, which does not require equipment and minimizes risks of injury, is raised as an accessible alternative to combat the loss of muscle mass and the fragility of age, combining physical benefits with the cultural value of an ancestral tradition adapted to the challenges of modern health. Preventable tragedy. Be that as it may, each fall that causes fractures, brain injuries or dependence is a devastating event that alters lives and generates huge costs. The paradox is that many of these deaths They could be prevented with a more rigorous control of the prescription and with programs that prioritize non -pharmacological interventions. The key, in the case of the United States, points to patients and caregivers demanding their doctors Check the treatments and raise alternatives, because often that conversation does not happen. The increase in deaths from falls in the elderly, far from being an inevitable consequence of aging, reflects failures in the care model and opens an urgency: to balance the extension of life with the quality and safety of those years won.

Before the great fire wave in Spain, science already has a culprit of its propagation: climate change

by

This 2025 It has been a devastating year for Spain and Portugal Because of the A large amount of forest fires that they have been giving, In many cases intentionallybut that were fueled without control. A new scientific analysis has concluded that the climatic crisis has played a determining role, multiplying by 40 the probability that the extreme weather conditions that fueled the flames would be given. Not just that. The study determines that these phenomena were 30% more intense than they would have been in a world without global warming. And this is important to highlight it: the study does not indicate that climate change causes fires, but they intensify their force of destruction when they make them uncontrollable more likely. Putting figures. The reportprepared by the World Weather Attribution network, put figures to a catastrophe of historical dimensions. On September 1, the fires had calcined about 380,000 hectares in Spain and 260,000 in Portugal. In total, 640,000 hectares, an area four times higher than that of London and represents approximately 1% of the surface of the Iberian Peninsula. In historical terms, for Spain 2025 it will close as the fifth year with the highest burned surface since there are records in 1961. If we are going to European, we can affirm that the worst year since The EFFIS system (European Forest Fire Information System) began registering data in 2006, with more than one million hectares calcined, being two thirds of those corresponding to Spain and Portugal. Impresses researchers. “The size of these fires has been amazing”, affirms Clair Barnes, scientist at Imperial College in London and co -author of the study. “Warmer, dry and flammable conditions are becoming more severe with climate change and are giving rise to fires of an unprecedented intensity.” And it is that the surprise is logical. According to the data they have analyzed, they point out that these extreme risk conditions for the propagation of fire will be given every 15 years with the current climate. This is something that only happened once every 500 years in the preindustrial era. An explosive cocktail. The fuel of these megaincendios was an unprecedented weather situation. The large amount of fires occurred during a heat wave in Spain that was one of the longest ever registered, with a duration of 16 days (from August 3 to 18). But it was not only the longest, but also the most intense, with an upper 4.6 ° C temperature anomaly compared to a pre -industrial climate. The impact of climate change in this extreme heat is even more pronounced. According to the analysis, a ten -day heat wave as intense as the lived is now an event that is expected once every 13 years. Before humans began to heat our environment, such a heat was extremely rare and it was only expected to happen less than once every 2,500 years. It is not just the weather. Although the report points to climate change as the great amplifier, it is not the only factor. Scientists highlight that both in Spain and Portugal, rural depopulation and population aging have left large extensions of forest land without managing, creating a massive accumulation of dry vegetation that acts as a perfect fuel. One of the examples that is put is in the decrease of traditional practices such as extensive grazing has reduced natural control over that vegetation. David García, applied mathematician of the University of Alicante and co -author of the study, points out that the public debate in Spain has focused a lot on the decline of these rural activities. It points to that “much less the effect of climate change has been discussed in these fires, which, as has been demonstrated, has been immense.” To this is added that human ignition, whether accidental or intention, is behind about 90% of fires whose causes are identified. With huge fuel loads and extreme weather conditions, minor human actions can trigger catastrophic results. The science behind. To reach these conclusions, the research team analyzed the weather conditions that the fires propitiate using the daily severity index (DSR), which is a metric derived from the Canada Fire Meteorological Index (FWI). In summary, this index combines long -term rainfall data, temperature, humidity and wind to estimate the probability and severity of a fire. In this way, the scientists compared the meteorological data observed in the current climate (which has been heated from the pre -industrial era) with a counterfactual of how these conditions would be in a climate without that warming. In this way, with the methodology used, the “footprint” of climate change in a specific extreme event can be isolated and quantified. The result. The climatic crisis is taking the ecosystems and response capacity to the limit. For the first time, Spain activated the EU Civil Protection mechanism to request help in the fight against forest fires, and now they are already raised to apply new regulations with the aim of preparing for the future that awaits our country.

Chinese mobiles have batteries 11% higher than those in the rest of the world. The culprit is called sic

by

Chinese smartphones have a clear advantage: their batteries are 11% larger than those in the rest of the world. A consolidated suspicion that is now measured thanks to Counterpoint Research. The average in China reached 5,418 mAh in May 2025, compared to 4,900 mAh in the rest of the world. The difference has expanded to exceed 500 mAh in recent months. Why is it important. China is adopting carbon-silicio batteries (sic), a technology that allows greater energy density without increasing the thickness of the device. The rest of the world maintains more conservative technologies even though Two years ago we warn of this impact. The context. Chinese brands have opted to solve one of user’s biggest headaches: autonomy. With larger screens, more frequently soda and applications that consume more energy, including Local generative AIThey need more capacity. 6,000 mAh or more mobiles already represent 35% of the Chinese market, compared to 9% of a year ago. OnePlus leads with the greatest average capacity thanks to Your Ace series, exclusive to China. There is a revealing pattern: brands such as Honor, Huawei and Vivo launch models with larger batteries specifically for the Chinese domestic market. But their global versions maintain minor capacities. Why does this happen? Because China is its test laboratory: SIC batteries certifications are more agile there. In China you can try that technology before facing the expensive and slow western approval processes. It is cheaper to try at home than to risk out with a new technology. And now what. China will maintain this short -term advantage while Western brands wait for SIC technology to mature. The gap will be reduced when more manufacturers adopt large batteries as a global differentiation factor, and not only in China.

Ouigo excuses himself from the collapse in the bird and believes to know who is the culprit

by

They were “13 hours trapped in the middle of a plain”. And, since then, the Government, Ouigo and Adif are trapped in a major battle. Specifically, to find a culprit to the collapse of high Andalusian speed last week. Thousands of affected travelers, many unknowns and only a safe thing: nobody wants to peeled. “A Sinking”. “How to attribute responsibility in the sinking of a road to stuck cars, something frequent and habitual.” This is how Ouigo has described in a statement, collected by Europa Pressthe report derived from the collapse of the high speed that was lived on June 30 when hundreds of travelers from the Andalusian corridor their trains were stopped But, above all, when the passengers of one of those trains spent the night in the bird, No water and without being rescued. That report has elaborated Adif And he points out that an Ouigo train was to blame for the collapse of the network. According to the infrastructure manager, the French company train “lost the check with the signal systems standing on the road.” That caused four other trains to stop, causing the dominated effect already conspired. Adif points to Ouigo … The report, collected by The worldHe points out that the French train stop accumulated up to five trains in seven kilometers of tracks. The manager explains that the catenary tension is designed to feed a train in motion but not to keep five trains active at the same point. In that case, there is a risk of over -overtime. When this happens, the train is disconnected from the catenary to avoid greater risks but causes a tension drop in the line. It is something like lowering the leads at home so that appliances do not shrink with a voltage rise. The whole system is controlled by the pantograph. This manages the electricity between the train and the catenary and is the one that is supposed to be in the Avant de Renfe that remained in the middle of nowhere. That is, Adif points to Ouigo as the seed that ended up creating chaos. … ouigo blames Adif … “This cannot be used as an alleged cause of the tension drop in the catenary. The infrastructure must normally contemplate this type of situations.” Ouigo said in the aforementioned statement to subsequently underpin the phrase with the previous metaphor. The company emphasizes that Alstom’s MEPs, the trains with those operating in Spain, are one of the “most reliable and insurance models in Europe” while emphasizing that they will collaborate in any request for information that is requested from ADIF to clarify what happened. … And the government puts the eye in ouigo. The mention of trains safety is not accidental. Last Wednesday (July 2), at a meeting between Addar and the PSOE, María Jesús Montero, Vice President of the Government and Minister of Finance, was hunted by an open microphone. There he could say that the maintenance of “the ouigos these” was not correct. “We from Renfe remove them, which do not remove the trains from the tracks,” Montero was heard to tell various representatives of adding, in words collected by the media, among which is 20 minutes. “Apparently there is a problem too, well, of those operators, and I plan to raise it. I do not know if there is a certain sabotage, I cannot understand it, I am a user of that bird, it is my usual means of transport,” Montero insisted. More investment with canons flying In addition to defending themselves, from Ouigo they have insisted to Adif on taking into account their demands of greater investment in the maintenance of the infrastructure. They point out that the situation lived last week is “unpublished and unacceptable”, in the words of Helene Valenzuela, CEO of the company in Spain, during the IV Mobility Forum organized by The economist. They ensure that the projected image directly affects high speed and believes that The ADIF Plan It is not enough because “you cannot identify all the weak points of the network.” That is why they demand a greater investment at the time that the canons that the manager wants to apply to the operators for the use of the infrastructure. Until now, Ouigo has pointed to the canons as the main reason why they are not profitable on their arrival in Spain. That absence of profitability has been denounced by the Government who even warned that would denounce Ouigo against Europe for unfair competition.

A strange night a whistle has been listening for weeks in Vigo. They just found the culprit

by

There are phenomena whose sounds They challenge not only reason, but even the very perception of reality. One of them is remembered in Scotland Since the late 90s, a low frequency buzz that is heard in different enclaves and that in recent times he has returned strongly. In Spain something similar to this part happened in an area of ​​Vigo. Weeks with acute noise when the night that had altered the dream of the neighbors. The problem is that they have just detected the “guilty”, and has a difficult solution. The mystery had wings. It The Faro de Vigo had. For weeks, the neighborhood of Vigo’s journey and Aragón Street has lived in confusion and irritation because of an acute, intermittent and persistent beep that began at nightfall and repeated every two or three seconds until dawn. The initial suspicion fell to multipable guilty: a spoiled alarm after the blackout of April 29, a port of the port amplified by the wind, or even some damaged traffic light out of decibels. The neighbors, unveiled and perplexed, mobilized to find the origin of the annoying sound, called 010, patrolled the streets in search of sound tracks and requested the intervention of the local police. In the end, neither industrial alarms nor port machinery: the author of the beep has turned out to be An unexpected creature and surprising, whose presence had gone unnoticed until then because of its historical silence and its expertise for camouflage. Small and nocturnal. Yes, apparently, the Local Police, after inspecting the area and confirming that it was not any mechanical source, identified the person in charge: a European autillo (Otus Scops), one of the smallest raptors in Europe (does not exceed 20 cm in length or 100 grams of weight) whose song remembers a high frequency electronic whistle. In fact and how I told the middle The biologist of SEO BirdLifeGustavo Ferreiro, the repetitive beep is part of the AVE mating ritual, which is in this time in an incubation phase. In other words: the autillo does not sing to bother, but to communicate its presence, claim territory and maintain the link with your partner during the breeding. Invisibility. Although common in southern Pontevedra, his nightlife and his perfect camouflage among the trees make him an almost inhabitant invisible which can only be detected by your voice. In this caseHabitat’s choice was an urban environment with dense vegetation and old trees, which surround the Matías Park and a nearby abandoned house. European Autillo Survival paradoxes. The case also offers other readings. The paradoxical is that The European Autilloonce a rural bird, it is today forced to take refuge in urban environments due to the loss of biodiversity In the field. Agricultural intensification has eliminated large trees, essential for nesting, and the massive use of pesticides has decimated insect populations that are fed. Thus, the natural habitat has degraded to such an extent that birds seek shelter in urban parks, where they can still find cavities and some food. This forced migration to the city is a reflection of the ecological decline in which the species is found, already included in The “vulnerable” category In the Red Book of the Birds of Spain 2021. Thus, the presence of the Autillo in Vigo is not an isolated anomaly, but rather a symptom of a deep change in the distribution and behavior of many species affected by human pressure on ecosystems. Endangered species. The case of the beep in Vigo demonstrates how a daily discomfort can actually be the life sign of an endangered species. What began as a sleep disturbance became an opportunity to reflect on coexistence between the city and nature. The case reminds others where the presence of cities ends up modifying the life of species. In fact, in Valencia something similar has happened With another copy. EITHER In Icelandwhen the frailecillos season begins and humans hunt them and throw them through the cliffs (by A good reason). In this case, climate change and cities lights threaten the survival of birds. With the autillo, the loss of biodiversity is what is throwing them into such Obern Like cities. That said, and if everything follows its course, the song will send for the neighbors in August, when the chicks and the priorities of the bird change from the courtship to the care.

North Korea was going to throw his greatest war boat and ended up sinking it into the sea. Everything points to a culprit: Kim Jong-un

Making a fool of it is something that It is not anyone’s pleasure. Surely you have ever stumbled down the street and looked around to see if someone had seen you. Now, imagine that what stumbles is a Military ship of 5,000 tons and several million dollars and sinks at the time of its premiere. That is what happened last week when Kim Jong-un He witnessed how His brand new war ship sank before the impotence of all those present and under the watchful eye of the rest of the planet. And everything indicates that the error was because, as the Spanish proverb points, the hurry are not good. Short. Days before the event, satellite images They showed both the vessel and a scenario in which what seemed to be an observation zone. Probably, the place from which Kim Jong-un was going to witness that historic moment. And the truth is that it was historic, but not for the reasons he would have wanted. On May 23, during the launch ceremony of the new North Korean destroyer (the second of its most advanced class), all attendees in the front row and the world was witnesses of a Technical failure that ended in disaster: the ship overturned. That symbol of power, with 143 meters in length and 74 vertical missile launch cells, ended up ridiculous. How do we float it? Satellite images later Analyzed by the Center for Strategic and International Studies, or CSIS, they showed the ship partially sunken with tarps that covered the disaster. And, although at first the rush was blamed, we now have more clues about everything that could go wrong. Obviously, there is no official information from North Korea, but in The New York Timeswe can see that there are analysts who are quite clear what the problem was. Or the sum of them. Image | CSIS/BEYOND PARALLEL/MAXAR When a ship is finished, there is Several ways to ‘throw it’ into the water. We have the sliding launch in which the ship slides on a ramp into the water. The dry dock in which the ship is built in a dry dock and, once finished, the water dike is filled (That is done with cruises). Also the mechanical launch by cranes, the launch with airbags that are placed under the ship and allow it to slide to the water. And the side launch that drops the side ship into the water. Normally, a single technique is used, but in the North Korean destroyer disaster it seems that sliding and side techniques were used. And not because that’s how it was planned. Perfect storm. As noted The New York TimesIt was the first time that analysts watched North Korea use the side launch to throw a war ship. This technique is sure if it is done well, but in Large ships It is more likely that a problem appears, with dire consequences if it happens. The reading of the analysts is that, using that technique for a 5,000-ton ship points to a lack of experience added to the political pressures by Kim Jong-un to achieve rapid results. The destroyer was manufactured in the port city of Chongjin that has experience assembling ships of such magnitude, but not something as huge as this ship. This puts on the table that a possible trigger was that inexperience When throwing such large ships. In the absence of a dry dike of the appropriate size, it is estimated that the engineers tried the lateral launch to throw it into the water, but the angle was not correct and, when trying to slide it, the ship was unbalanced and ended up lying on the right side. When it goes well, as happened with this fighting ship of 3,500 tons in 2013, it is worth seeing: And it can also go wrong: The hurry are not good. Interestingly, this destroyer is from Choe Hyun classwhose first model was inaugurated successfully Last month. It was going to be the second great frigate of North Korea and the new example of that naval remodeling that Kim Jong-un is promoting. And the precedents were good: the first It was built In the city of Nampo and, because it is a larger shipyard, they could put it afloat through the technique of dry dock. There were no major problems and, at the inauguration, the ruler saw how test missiles were thrown successfully. However, there are hurry in the government dome to follow demonstrating to the world its military potentialwhich has led the president to visit the shipyards who are building new ships to accelerate delivery deadlines. In addition, there are information They point out that, although the ship could have thrown out correctly, the ocean exit street is narrow and has a questionable depth. I made a. pic.twitter.com/urflog6leo – Dr. Jeffrey Lewis (@armsControlwonk) May 22, 2025 Firm hand. And who will pay for this? At the moment, the ridiculous has resulted in several arrests of members of the responsible shipyard itself. The Central News Agency of Korea reported that the chief engineer, a senior armament official and another member of the installation had been arrested, and Kim himself described The accident as a “criminal act”, demanding An urgent restoration of the ship before June. Country engineers estimate that, pumping seawater, they can straighten the ship and repair damage. And it will take about ten days to do it, but it seems complicated because, after a week, Keep as it was. Sentinel-2 images of May 23 and 28. Despite the clouds, we can see that the destroyer continues exactly at the same point And sarcasm. From South Korea, which always have an eye and a half placed in what their neighbors doThey think something else. Yang UK is an expert in North Korean military affairs of the Asan Institute for Policy Studies in Seoul and, as Tnyt comments, the incident may not be only an accident, but something caused by a structural imbalance on the ship itself. … Read more
