AI has caused the collapse of even a non-AI industry: gas turbines

by

When everyone runs away, Meta’s former CTO stays. While the majority of Silicon Valley investors have abandoned the C thesisfile Tech —tired of promises that do not turn into real business—, Mike Schroepfer just announced that it has raised 250 million dollars to do exactly the opposite. Its background, Gigascale Capitalhas closed its first round with institutional investors to back founders who, in their own words, are “rebuilding the brick-and-mortar economy.” The news comes at a time when the climate technology sector has a difficult reputation. As explained TechCrunch, “Conventional wisdom” has been soured by the “Climate Tech” label. Schroepfer, known in the industry simply as Schrepis challenging the market consensus. Or as the same media describes it: “Zigging when most are zagging” (zigzagging when everyone goes in the other direction). Does this bet make sense? First of all, we must understand the underlying problem: gas turbines, the most conventional electricity generation system that exists, currently have a waiting list that extends until the early 2030s. It is not that there is a lack of green technology, it is that there is simply a lack of energy. And companies trying to connect to the electrical grid are finding it increasingly difficult. The person responsible. And the question is, who has accelerated that demand to this point? Artificial intelligence. The sector has undergone a structural change in recent years, driven precisely by the energy demands of AI. Data centers consume huge amounts of electricity and networks cannot cope. Faced with this situation, many companies are trying to generate their own electricity. As Schroepfer himself notedthe “bring your own energy” model (Bring-Your-Own-Power) will become a decisive competitive advantage in intensive industries. But there is no easy path there either: even traditional turbines have a waiting list. As Pulse 2.0 detailsaccelerated electrification, industrial relocation, AI deployment and increasingly extreme climate events are simultaneously putting pressure on physical infrastructure that has been aging for decades. The business of scarcity. The company, Gigascale, was founded in 2023 by Schroepfer along with Victoria Beasley and Evaline Tsai. The fund emerges from a process that the former Meta executive describes as a systematic study of the climate sector during the pandemic. In three years they have built a portfolio of more than 25 companies in areas ranging from clean energy and grid infrastructure to critical minerals, advanced manufacturing and what they call “physical AI”: applications of artificial intelligence to design, manufacture and deploy real-world systems. Schroepfer’s investment logic does not pivot on environmental virtue, but on competitiveness. Their argument is the following: solar went from producing 40 gigawatts a year to 600 in a decade because it became cheaper. “The companies we support win because they are cheaper, faster and more reliable. This is how adoption scales. Climate impact is the result of systems that work better,” declared in a statement. When the waiting list is the opportunity. The fund’s portfolio already has specific names that illustrate this philosophy: New energy generation: Commonwealth Fusion Systems and Xcimer Energy (which achieved the first flash of its commercial laser system in late 2025) are working to make nuclear fusion a reality. For its part, Radiant is moving toward one of the first commercial deployments of nuclear microreactors in the United States. Infrastructure for AI: Arbor Energy has signed an agreement with GridMarket to supply up to 5 gigawatts of clean, zero-emissions energy to data centers. In parallel, Fractile announced a $136 million expansion to manufacture AI processors specifically designed to reduce electricity consumption. Circular and industrial economy: Heron Power, founded by Drew Baglino – former Tesla vice president for propulsion and energy division – develops industrial power electronics. In addition, companies like Dioxycle have signed multi-year agreements with giants like L’Oréal to convert captured CO₂ emissions into ethylene to make packaging. There is an underlying irony. The world has been debating for years how to decarbonize for environmental reasons. And it turns out that the catalyst that is making the transformation of the energy system urgent and inevitable is not any climate summit: it is Artificial Intelligence. As investors flee the label Climate Tech Considering it too ideological or unprofitable, the demand for energy is so brutal that not even the most conventional gas turbines can cope. The opportunity exists precisely because the problem is real. And Schroepfer, who comes from building the systems that consume that energy, is very clear about it.

We would need to detonate Earth’s nuclear arsenal 130 times to release the energy that caused the Moon’s great cannons.

by

The Moon has its own “Grand Canyon of the Colorado”, and doubly so. Only these two canyons were not caused by the slow erosion of a river like the Colorado: 15 minutes of destruction were enough to leave these two enormous scars on the surface of the Moon. 10 minutes of destruction. A 2025 study analyzed in detail two enormous geological strips located in the vicinity of the south pole of the Moon. The analysis has determined, among other conclusions, that they were formed by the impact of an asteroid or comet and that the impact was such that these canyons were formed in less than 15 minutes of destruction. Two large cannons. Their names are Schrödinger Valley and Planck Valley and they are two enormous geological strips that radiate in a straight line from a point located in the Schrödinger basin, near the lunar South Pole, not far from the place chosen by NASA to the return from humans to the Moon. The study has offered us new data on the magnitude and morphological characteristics of these two sores on the surface of our satellite. These two canyons have a length of 270 and 280 kilometers; and 2.7 and 3.5 kilometers deep, respectively. An immense force. In addition to analyzing the characteristics of these two strips, the study tried to characterize the impact that caused them. By studying the way in which these were excavated, they determined that the process lasted between 4.9 and 15 minutes in one of the cases and between 5.2 and 15.4 minutes in the other. That is, they only needed about 10 minutes so that the impact would destroy tons and tons of lunar rock. The impact would have been enormous. According to the team responsible for the study, the energy required to produce these cannons would have been 700 times greater than the energy released by the nuclear tests of China, the United States and the USSR, and 130 times greater than the energy in the world inventory of nuclear weapons. Details of the study, like this last one, were published in an article in the magazine Nature Communications. The best analogue of the Chicxulub crater. The impact would have occurred billions of years before the one that caused the extinction of the dinosaurs on Earth. However, the team responsible for the study maintains in their article that this lunar impact is the “best analog expression on the surface” of the Chicxulub crater.

2,500 years ago Athens suffered an epidemic that marked the end of its golden age. Science is determined to know what caused it

by

“Words are insufficient when trying to describe this disease. As for his suffering, it seemed almost beyond what is humanly bearable.” Although the news about the hantavirus They make it sound even scarier, that commentIn reality, it is more than 2,000 years old. The chronicler Thucydides wrote it in his ‘History of the Peloponnesian War’ to give an idea of ​​the terrible plague that devastated Athens around 430 BC, an ailment that he himself suffered and took the lives of some 75,000 people. For centuries that epidemic has been remembered as the ‘plague of Athens’although we don’t actually know exactly what caused it. Now a group of Greek researchers have shed some more light on that dark episode. Epidemic detectives. In a hyperconnected world, in which people are capable of traveling thousands of kilometers in a few hours and it comes with blocking a remote strait of the Middle East to put the world economy in check, the specter of pandemics seems more present, but the truth is that humanity takes centuries dealing with him. Before the COVID pandemic, we had, for example, the 1918 flu or the disastrous Black Deathwhich devastated Europe between 1346 and 1353 and (by some estimates) reached 60% case fatality rates in some regions. Long before any of them, in the times of Classical Greece, another equally devastating epidemic was recorded: the plague of Athens. Thanks to authors like Thucydideswho in addition to being a chronicler suffered it himself, today we can learn in detail how that outbreak developed and experienced, which left tens of thousands of dead. The episode was important not only because of its death toll: between 75,000 and 100,000 in the four years that elapsed from 430 to 426 BC One of the deceased was Periclesa historical leader of Athens. In fact, experts usually agree that the plague precipitated the decline of the Athenian Golden Age and its death toll facilitated its final defeat in the war against Sparta. The great unknown. Despite this historical value, the Athenian plague remains shrouded in unknowns. We know when it developed, we know where it developed and there is even evidence suggesting that the initial outbreak occurred in sub-Saharan Africa, spread to Egypt and Libya and then passed to Athens via Piraeus. What is not clear is what exactly caused the plague and why it was so disastrous. And Thucydides was in charge of describing all its symptoms. Now a team from the University of Athens (NKUA) have wanted to clear up this mystery by analyzing the symptoms described by the chronicler and comparing it with that of known ailments. The result they have published it in the magazine AMHA. A pulse on history. If it is difficult to track a viral outbreak in 2026, the task becomes daunting when we are talking about one of the first known epidemics in human history. To face such a challenge, Dr. Dimosthenis Papadimitrakis and his colleagues had an idea: they looked at the symptoms described by Thucydides and other sources, They selected 17 diseases known that more or less fit that symptomatology and created a “metric system” with different scores to determine which of them best fit the epidemic that hit Athens 2,400 years ago. “The most terrible thing, despair”. Whether due to his zeal as a chronicler or because he himself suffered from the disease, Thucydides detailed the symptoms suffered by those who contracted the Athenian plague: migraines, high fever, redness and inflammation of the eyes, bad breath, sneezing, cough and profound gastrointestinal discomfort, such as nausea, vomiting, spasms and painful diarrhea. Over time, rashes, pustules and ulcers appeared on the patient’s skin, especially in the abdomen area. Those who could not stand the disease died after seven or nine days, after experiencing intense burning that led them to take off their clothes or even immerse themselves in cold water. “Gangrene of the extremities and eyes was common among both survivors and victims,” detail experts, who remember that it was not unusual for patients who survived the plague to do so with amnesia. “The most terrible thing was the despair into which people fell when they realized that they had contracted the plague. They immediately adopted an attitude of absolute hopelessness and, by giving in in this way, they lost their capacity for resistance,” Thucydides reflects. “Words are insufficient when trying to give a general image of the illness.” Ruling out candidates. With that starting point, Papadimitrakis and his colleagues developed a list of diseases that the Athenians of 2,400 years ago could have contracted and that coincided to a greater or lesser extent with the symptoms described by Thucydides. They came up with 17 potential ‘candidates’, including cholera, measles, scarlet fever, tuberculosis, Ebola, malaria, smallpox, bubonic plague, ergotism or Lassa fever. Then with that chart on the table, two questions were asked: Which of those diseases caused rashes and gangrene? How many are transmitted between humans? And what historical evidence is there for each of these ailments? Thanks to this analysis they reached a series of conclusions, although the team warns that they are only hypotheses based on probability, not firm and unquestionable truths. “The plague of Athens presents difficulties in identifying the causal agent due to several factors. The main source of information is the accounts of Thucydides, but his lack of medical knowledge and the lapse of up to 20 years between the events and their documentation can lead to erroneous interpretations,” the authors explain. “Furthermore, the inability to isolate or culture the responsible microorganism poses a major obstacle. Even if preserved bodies of plague victims were discovered, the microbes would have decomposed over time.” And what is the conclusion? That of the diseases analyzed, the one with the most votes is typhoid fever. “It appears to meet most of the criteria, so it is considered the most likely agent,” summary the researchers. Furthermore, in a necropolis from the time of the epidemic, remains of the bacteria that trigger this disease … Read more

In 1944, the Nazi occupation of Holland caused a brutal famine. And thanks to her we discovered celiac disease

by

The history of wheat is the history of civilization. To be more precise, this cereal is linked to the change from Paleolithic to Neolithic societies, the first complex societies, in 8,500 BC. C. The flowering of our species came thanks to its golden seeds. We had to wait almost 10,000 years to verify that this manna, which for many is synonymous with life, for some of us, is synonymous with death. And, in part, We have the Nazis to thank.. We are in Holland in 1944, in the throes of World War II, and the Wermachtwhich has occupied the country, is fed up with the sporadic rebellions of its native population. The railroad strike carried out by the drivers was reason enough to implement an embargo on food transportation to the northern areas. Survivors interviewed half a century later mentioned how the Hongerwinter or “hunger winter” still sparked flashes of anguish in their minds. According to reports from the time, in areas such as Amsterdam or Rotterdam the shortage caused rationing of 580 kilocalories per adult per day. Faced with this situation, and when a crust of bread could be more precious than the family watch, the Dutch began to eat anything. Your tulips also fell into that category.which in addition to being disgusting and having a negligible energy value, were a food source highly discouraged by doctors, since its toxicity was very high. Would the tulip diet be the beginning of poisoning and indigestion for the population? Yes for the majority, but not for one notable group: the patients at the Juliana Children’s Hospital in The Hague. Discovering celiac disease A child during Hongerwinter. Willem Karel Dicke, a pediatrician, had been investigating these “malnutrition” problems that mysteriously attacked the little ones for some time. In the 1940s, the world average Infant mortality for children under five years old was 15%so, although it was a misfortune, the population was more used to losing children than we are now. Many parents would not have the time or the resources to investigate what caused their children’s weakness, nor would they have the considerations to experiment with their diet, much less if that meant removing the most widespread, convenient and cheap product of all, bread. Although some, the richest, could afford it. For them, the theory of intransigence towards complex nutrients ran at that time, which led to the popularization of the so-called “banana diet”. A regimen that worked, given that this fruit does not contain gluten, but with which adverse effects reappeared in the subjects in their adulthood, as soon as they returned to eating wheat derivatives. As any celiac or person who has lived with one knows, the ubiquity of this product in our pantries is scandalous. Pediatrician Willem Karel Dicke with one of his patients. But in the Netherlands of 1944 there were no bananas. Because there wasn’t there was practically nothing. And yet, despite the lower caloric intake in which society was imbued and the toxic effects of tulips, a good percentage of the children in his hospital felt better than months before. While people were dying in the streets, some children saw how their limbs were getting fatter, their bellies were deflating, and their skin was glowing. If before that episode one in three children with suspected celiac disease died at that time in the Netherlands, the winter of hunger meant that that percentage would fall to zero. What came next is the mere work of field observation. Dicke spent the next few years testing on selected patients. different cerealsmeasuring the weight, growth, general health of the subjects as well as the levels of fat absorption from their feces. By 1950 he was able to publish his findings, which had determined that the cause of “celiac symptoms” came from wheat and rye flour. And no, it had nothing to do with complex nutrients, as had been assumed until then. “Koiliakos,” that mysterious condition that humans had identified in some children since Ancient Greek times and that intrigued pediatricians for millennia, finally had a name and diagnosis. His research earned him a candidacy for Nobel Prize in 1962, but died weeks before the ceremony could take place. Since it is an award that is not offered posthumously, Dr. Dicke missed his chance to go down in the history books in this way. Celiac disease continues to be one of the conditions with the most complex diagnosis, since it is confused with other types of digestive pathologies and its effects manifest in the strangest ways. Without going any further, neurogluten studies How gluten intolerance is behind autism, Parkinson’s or depression. We also do not know how many people suffer from it, and although its existence was known in the 1950s, its diagnosis rate may continue to be lower than the real rate. Today in developed countries there is talk of between 1 and 2% of people with celiac disease and recent epidemiological studies suggest that the disease is possibly ten times more common than it is diagnosed. The percentage of celiacs continues to grow at 15% every year. In Xataka | When the Black Death devastated the continent, Europe became obsessed with a reflex action of the body: sneezing.

For decades we believed that extreme nausea during pregnancy was caused by “hormones.” A large study found the real culprit

by

The beginning of pregnancy for many is associated with horrible nausea and vomiting that have become almost an inevitable and deeply annoying toll in pregnancy and that many women fear. And the reality is that, for a percentage of these women, nausea becomes a big problem and evolves into a very serious form called hyperemesis gravidarum. What was believed. At first, the most classic reviews They pointed squarely at the ‘hormonal dance’ that pregnant women experience while the placenta is forming. Here the peaks of human chorionic gonadotropin (which is the hormone that pregnancy tests detect), along with estrogens and progesterone, were the main responsible for this discomfort. However, in clinical practice, the exact cause remained uncertain, since it was not understood why some women only felt mild morning sickness and others ended up hospitalized due to the severe dehydration caused by vomiting. And the answer was in the DNA. A great study. Here science has dotted the i’s with an article published in Nature which has analyzed the data of almost 11,000 cases of hyperemesis gravidarum and contrasted it with more than 420,000 women who did not have this problem. The result. He targeted ten genes associated with this severe form of extreme nausea, but among all of them the GDF15 gene emerged as the main culprit. And here the different experts point out that the developing fetus and the placenta produce the hormone GDF15, which is produced from the gene that we mentioned before and sends it directly to the blood, causing this nausea. Although the key is not just how much hormone is produced, but the degree of prior exposure the mother had to this hormone before pregnancy. In this way, women who had low levels of GDF15 before becoming pregnant turn out to be much more sensitive to the sudden surge of this hormone from the fetus, which triggers the most severe symptoms of nausea and vomiting. A discovery with evidence. Despite the forcefulness that accompanies this evidence, the study suggests that the gene GDF15 It is the main cause, but not the only one. The fact that there are other genes involved demonstrates that hyperemesis gravidarum is a multifactorial condition so calling it the “sole cause” would be scientifically inaccurate, but classifying it as the most determining genetic factor is, today, a fact supported by the best peer-reviewed literature. What does it mean? Identifying GDF15 as the main biological switch of this problem is undoubtedly the first step to be able to apply a treatment that can help these future mothers who suffer from significant vomiting during pregnancy, and especially in the first trimester. Although it is true that this does not explain many other symptoms of pregnancy, such as heartburn or that some things begin to feel bad ‘just because’. Although there is still a lot of research ahead to discover them. Images | tirachardz on Freepik In Xataka | We have been sending pregnant women to bed for decades as a precaution.

How the Black Death caused Europe to become obsessed with the act of sneezing for centuries

by

Hebrew tradition tells that, just before biting the apple, Adam sneezed. At that moment it seems that he didn’t care much, but after the incident with the fifth piece of fruit a day he ended up interpreting it as “a sign of evil and a harbinger of death.” The noise stayed there, of course, and when the very old Jacob was worried about not getting to see his son, he begged God to change the natural order of things lest a bad sneeze take him to the other neighborhood. That’s where it comes from (collected or perhaps invented anew by medieval tradition) that we desire “health” in Spain, “saúde” in Portugal or “Gesundheit” in Germany to someone who has just sneezed. As if to ward off bad omens; that life is not enough to play with dice. However, because it is common, I still find it surprising how much a simple sneeze has come to mean. Aristotle, explains García-Morenowas convinced that, compared to flatus or belching, the sneeze was the only one that had a ‘sacred nature’ because it came “from the main and deepest and most divine of the organs, the one that contains the spirit.” Hippocrates, on the other hand, although he did not decide on the goodness or badness of sneezing, he did describe the principle of reciprocal inhibition by pointing out that sneezing was, mind you, the best remedy for hiccups. As I said, the history of sneezing in the West cannot be understood in all its complexity without the Black Death. It was then that the “health” of the Jewish tradition or the “Jesus” of the Christian tradition became popular again as a way of wishing that this ‘achís’ was not the doorway of the damned plague. The “God bless you” that still resonates in English formulas (‘bless you’) comes, it seems, from one of the many plagues that struck medieval papal Rome. In contrast, in many other places, sneezing was considered a good thing. Fantastic. Traditional Hindu medicine used to provoke it as a way to balance internal humors and treat illnesses while the more archaic African medicine used it protopsychiatrically as a way to cure mental illness (supposedly caused by the existence of worms in the brain). To finish, to finish at some point, the Aztecs used it for headaches. What is a sneeze really? In reality, a sneeze is something very simple. It is a reflex actionsudden and compulsive, whose purpose is to expel large amounts of air through the nose and (sometimes) also through the mouth. It is, therefore, a physiological reflex that the respiratory system uses defensively. Therefore, it usually occurs when certain foreign particles irritate the nasal mucosa. And yes, I have used “usual” with all the intention in the world. As it seemsand these are average estimates, before each sneeze we inhale about two and a half liters of air. That is the first phase, the inhalation phase. At that moment, the abdominal muscles tense the diaphragm to increase the pressure in the lungs and force the air to come out through the nose at dizzying speed: between 70 and 130 kilometers per hour. The saliva that is usually expelled when sneezing can cover an area of ​​up to 8 square meters. And that is precisely what makes a sneeze one of the worst vectors of disease spread in the world. However, sneezing is most popular precisely when it is most harmless: in spring, summer or autumn. When it is caused by ‘allergic rhinitis’. A classic, indeed. This type of rhinitis, caused by pollen from trees, weeds and grasses, becomes the great recurring character in the lives of practically a third of the population. It is unbearable, unbearable, a cross. But, still, there are worse sneezes. Between 18 and 25% of the population sneezes suddenly when exposed to bright light. This is what is known as ‘photic sneeze‘and it’s an old acquaintance (and a cause of disability) of aviation pilots. Apparently it is hereditary and is produced by an anatomical proximity between the second cranial nerve (the ocular, responsible for carrying visual information to the brain) and the fifth (the trigeminal, which seems to be responsible for sneezing). When there is very bright light, excitation of the optic nerve can cause excitation of the trigeminal nerve. This signal is interpreted as irritation of the mucous membranes and releases a beautiful, annoying and enormous sneeze. Something similar (although this time linked to the medulla oblongata) may be behind people with a natural tendency to sneeze after eating, when they see something pleasant, or even during orgasm. It is already a bad idea, although used well (and even Aristotle would agree with this) it can be seen as a “wonderful” way to improve communication in the bedroom.

A year ago, the blackout caused the Spanish data network to collapse. The CNMC believes it has the solution

by

In April 2025 Spain suffered a zero energy of which, precisely now, we are going to begin to pay some of its consequences. I remember quite clearly being cut off, not being able to call or send messages via data connection. However, when I changed locations and arrived at my relatives’ houses, some of them could do it. The fall of telecommunications It was uneven in Spainand the CNMC has published a document with preventive measures in case a similar situation occurs again. What happened. The energy blackout that left Spain plunged into darkness resulted in a large part of the population being cut off from communication. However, some operators They managed to keep their mobile network active for hours. Backup generators, generating sets moved to each area, backup systems… The challenge for operators to maintain coverage in Spanish territory was a titanic challenge, quite dependent on internal logistics, the state of the reserve batteries (some of them run on fuel), and the network infrastructure itself They were variables that influenced such unequal conditions to be experienced. A single network. In its statement, the CNMC proposes that the four giants of the Spanish territory put roaming plans at the service of the population in emergency cases. The experience of other countries shows that it is viable to incorporate roaming plans between operators in case of emergency. In this way, in areas where this was necessary due to the unavailability of service in an operator’s mobile network, the networks could be prepared to quickly enable the basic telecommunications services of the affected users through roaming in the networks of other operators. According to the regulator, this is an “ideal measure to strengthen resilience”, but it is not so easy to apply. Yes, but. What the CNMC proposes is a cross-roaming service between Telefónica, Vodafone and MásOrange, something that requires coordination and agreement between the three giants. The best example is Sweden where, after two years of preparation, any mobile phone can connect to any operator. Go deeper. In addition to this proposal, the CNMC requests the mandatory nature of the alert system HANDLE in those cars with DAB+ radio receivers (the evolution of FM radio). Although DAB+ works via antenna (like AM and FM radio), its signal is digitally encoded. The ASA system allows you to automatically activate a DAB+ radio connected to power, being able to quickly launch alerts. At the moment, there is a distance from proposal to fact.

It is widely known that Orson Wells’ ‘The War of the Worlds’ caused a social panic. It is less known that it is a lie

by

In my years of training as a journalist I remember how they told us to study the radio broadcast of The War of the Worlds. My Radio and Television Information teacher told us that it was an exemplary event that could help us in the future practice of the profession to evaluate the responsibility of the media and to understand the mechanisms by which the so-called “fourth estate” could influence the social reality we serve. What perhaps the teachers who transmitted that information to me did not think is that they were right in what they had told me, but for a twofold and partially wrong reason. The legend of War of the Worlds The story is well known: HG Wells, a widely known science fiction writer at the time, had a story titled The War of the Worldsthrough which aliens would come to Earth to conquer humanity. A beginner but ambitious young man named Orson Welles decided to adapt the script to the radio format, giving it a newsreel structure for his television program. Mercury Theater on the Air on CBS and that he would read with other colleagues on the night of October 30, 1938, on Halloween Eve. The broadcast, the reading of this work, lasted an hour in which the aura of truthfulness was maintained except in three momentsone at the very beginning, another 40 minutes into the recording and another at 55. They indicated that it was a dramatization. For the rest, the fiction of that Martian invasion that was taking place in Grovers Mill, New Jersey, remained live. The myth, the documentaries and reports about the case and the journalism classes I attended said that Welles, the hired actors and the sound montages were so believable (and the audiences so naive) that within minutes of them starting to simulate a supposed alien attack the streets of the country were filled with hysterical and shocked masses. Panic attacks, people stockpiling supplies, collapsed police services and who knows what else. We assume that the people who did not hear those warnings were able to connect to the program after the warning and listened to the program without knowing that it was fake. And why wouldn’t we think like that? The newspapers of October 31 had carried the story to the foreground: “False war bulletin spreads terror throughout the country”, “Radio play terrifies the nation”, “Radio listeners panic, they confuse a war drama as a real chronicle”. These are some of the headlines that could be read about an event that, as it was said later, caused rivers of ink to flow in the form of more than 12,000 articles in newspapers throughout the United States. The reality is that, as a series of experts have reflected on different occasions, this interpretation largely falls into the realm of fake news. To support it here we use, above all, the study of professionals and experts from Princeton University, from the work of scholar David Miller in his essay Introduction to Collective Behaviorfrom the book Getting it Wrong by W Joseph Campbellfrom the work of sociologist Robert E. Bartholomew and from what journalists Jefferson Pooley and Michael J. Socolow have collected for Slate. What events did occur The broadcast did cause some effects. We know that some Grover’s Mill locals, believing their town’s water tower had been transformed into a “giant Martian war machine,” fired guns at the water tank. There was at least one woman who sued Welles and his team for causing her a panic attack and one man received direct compensation from the future film director who paid for the shoes that a listener said he had given up to pay for the train ticket he needed to escape the alien catastrophe. It is also true that calls to hospitals increased from people telling them where they could go to get donate bloodand police stations in the New Jersey area were also called, but most who did this were looking to find out if it was a false alarm. They wanted confirmation that it was a joke, but they also called to protest about this program that could be deceiving people or to congratulate them on that great special on that Night of the Dead. But nothing more. All of them came together to serve the approach that the written press wanted to give: that the CBS program had caused mass hysteria, that the radio was lying and deceiving its listeners and that they had created a major problem. And the lies that were published The rumor that people were being treated for shock in New Jersey hospitals was false, as the Princeton Radio office later revealed. The news that a man had died of a heart attack because of the program, as reported by the Washington Post, was also not true. People didn’t jump out of the windows either. In general, hundreds of articlesmany with supposed witness accounts, witnessed chaos that, in truth, had not been such. I remembered Some time later in his memoirs Ben Gross, radio director of the New York Daily News, that in truth the streets of New York They were half empty. It would also later be known that CBS had disconnected the Welles broadcast in different local affiliates in the country to show regional bulletins that, they assumed, would interest their audience more than a little play by Martians. The biggest scandal of all, the audience figures. It was said that more than a million people had listened to the program, when it could not be true. In fact, most people were listening to the NBC rival to ventriloquist Edgar Bergin’s popular radio show. And with most people we are talking about a 2% audience for the NBC show, as demonstrated by an independent survey that was done simultaneously with the broadcast. There is no doubt that in popular culture the idea that The War of the Worlds was a a before and afterthat the phenomenon must have been … Read more

In 2020, humanity was confined by covid. And that caused a species of bird to modify its beak to survive

by

During the COVID-19 pandemic the world stopped completely. Something that scientists have named ‘anthropause‘: a sudden silence of human activity that left many of us confined at home and that even affected nature. This effect was so extreme that even a species of bird changed its beak as science has now seen. The study. Although in the past we saw some disorders in nature, such as the appearance of wild boars in Barcelona or dolphins in Venetian ports, now a team from UCLA has gone further. a study published in PNAS indicates that a population of urban birds modified his physical anatomy in record time. The objective they had was to survive the absence of humans at that time. But the most surprising thing is that when everything returned to normal and humans began to go outside, the birds returned to their original beak. The dilemma. To understand the discovery, you first have to know the protagonists: the dark eyed juncos. Some small birds that are very common in the field of the University of California in Los Angeles. Before 2020, these birds had short, wide beaks. Something that makes perfect sense, since they were in an environment full of students and, therefore, His diet was based on leftovers. that were left This is why it needed to have a robust beak to handle these ‘artificial’ foods. In contrast, their relatives that live in wild forests have longer, thinner beaks, designed like precision tweezers to search for insects and seeds hidden in vegetation. The pandemic. When UCLA closed its doors in 2020 and the students disappeared, so did the easy food. And this was where the university researchers saw a unique opportunity to study what happens when you eliminate humans from the ecological equation. The results. What was seen in this case is the new generations of reeds that were born precisely in this time of ‘loneliness’ they developed longer and thinner beaks. All this because since there was no human garbage, they had to behave like wild birds again, foraging on the ground and looking for food alternatives. But what was most fascinating happened after the reopening. As soon as students (and their snacks) returned to campus in 2022, the morphology of the peaks quickly reverted to the urban form with a short, thick shape. This is ultimately an extremely rapid evolutionary change that is very rare to see. A change of mind. What makes this study so relevant to the scientific community is the speed of the field. Generally, we think of evolution as a process that takes thousands of years. However, what we observed here suggests that urban species have a much more elastic capacity for adaptation than we believed. Since it’s not just the peak. Previous studies by the same team had already noted behavioral changes: during the pandemic, these birds lost their fear of humans, becoming less aggressive and more curious, although that behavior also readjusted with our return. Its importance. This case is a brutal reminder of our ecological footprint. We don’t just alter the climate or the landscape; our mere presence and our waste acts as an evolutionary force that shapes the biology of the animals around us like these birds. The UCLA rushes have taught us that nature is not static; It is a dynamic system that reacts to our habits almost in real time. The question that remains in the air is: if a couple of years of silence changed the shape of a bird, what other invisible changes are we causing without realizing it?

Atomic clocks seemed untouchable. A blackout caused a difference in the official US time

by

To think that the official time of a country could fail is, at first, almost impossible. We are not talking about a domestic clock or just any server, but about the system that sets the pace of networks, satellites and critical services. That is why it is surprising to discover what happened recently in the United States. A power outage in Colorado was enough to remind us that extreme precision is not isolated from the physical world that sustains it. According to CBS, Xcel Energy applied a preventive shutdown to reduce the risk of fires due to very strong gusts of wind, and the NIST complex in Boulder was affected on Wednesday of last week. The power outage was followed by a backup generator in the institute’s laboratory. In that sequence, and according to information confirmed by NIST, the country’s time reference was slightly off for a brief interval, until part of the supply could be restored. Put a tiny deviation into context. The figure that came out of the NIST systems was 4.8 microseconds, that is, just a few millionths of a second different from what was expected. To get an idea of ​​that magnitude, NIST itself explained that A human blink lasts around 350,000 microseconds, a very different scale from the recorded mismatch. The variation is so small that for the vast majority of everyday uses it is irrelevant, but it serves to illustrate the extent to which even a minor deviation is measured, recorded and taken seriously in temporal reference systems. To understand why this offset is considered relevant, it is worth clarifying what exactly the official time of the United States is. The country is not governed directly by UTC, the coordinated international standard to which multiple nations contribute, but by a national implementation known as NISTUTC. Since 2007, that reference is established under the supervision of the Secretary of Commerce and the US Navy, and is adjusted to stay aligned with global coordinated timing. NIST-F4 Cesium Source Atomic Clock NIST calculates the official time from a weighted average of sixteen clocks spread across its campus, including hydrogen masers and cesium beam clocks, each with different functions and strengths. This approach allows us to gain stability and resilience, since the final signal is not conditioned by the behavior of a single instrument. Therefore, even when one of the elements of the system is affected, the whole continues to offer an extremely precise reference. What broke was not the watch. During the blackout, the atomic clocks continued to run thanks to their battery systems, as explained by NIST. The problem occurred in the connection between some of those clocks and the measurement and distribution systems that consolidate the final signal. When that communication was lost for an interval and one of the planned backups failed, the resulting time reference slowed down slightly. Technical personnel who remained at the facilities later activated a reserve diesel generator, which allowed part of the operation to be recovered and the system to be stabilized. NIST page The institute stressed that this gap has no appreciable effects on daily life. The nuance appears when looking at certain technical sectors, where extreme synchronization is an operational requirement. Critical infrastructures, telecommunications networks, positioning systems or some scientific environments work with such tight margins that even a minimal deviation deserves to be recorded and reported. The next step was to return to operational normality. NIST indicated that the correction of the gap will be carried out when all systems are fully powered and can be recalibrated with guarantees. Xcel Energy announced yesterday Monday that it was completing the restoration of service after the storm and the preventive cuts applied due to fire risk. Meanwhile, the institute began an internal review to evaluate the impact of the blackout and verify that redundancies and protocols responded as planned.
