“Treating scientific opinion as pro or con is oversimplifying”

Does it exist extraterrestrial life? Yes or no?. We often think that science evolves based on strong and solid statements. We have the perception that there is absolute agreement among all scientists in the world. “Science says so.” Thus, as if all scientists had a hive mind. However, those who rely on categorical statements, without asking questions, are characters like Marcos Llorentewith his yellow glasses and his fear of water vapor. Scientific knowledge, on the other hand, evolves through uncertainty and consensus that can change as research continues. This is what a team of scientists from Durham University is studying with their project C-SCOPE (Center for the Survey and Evaluation of Opinion of the Scientific Community). Its objective is precisely to understand how much consensus there is in some of the most important disciplines of science. Astrophysics is usually one that generates the most doubts among its own researchers, as well was seen in a recently published study. For this reason, they wanted to go further and analyze the opinion of hundreds of astrobiologists regarding the idea that extraterrestrial life exists. Two milestones about extraterrestrial life. These surveys were made in 2025, after two important studies were published pointing to a possible discovery of extraterrestrial life. The first of these studies was carried out with data from exoplanet K2-18bin which traces of dimethylsulfides and dimethyldisulfides were found, both substances that on Earth are related to biological activity. The second, however, took place much closeron Mars. In a rock on the red planet called Cheyava Falls, structures known as leopard spots were identified, which on our planet are related to microbial activity. When asking hundreds of astrobiologists about each of these studies, opinion was very divided. Of course, it seemed that there were a little less doubts with the second. The data. Regarding extraterrestrial life on K2-18b, 6.6% of those surveyed agreed to make this hypothesis, while 65.4% disagreed and 28% pointed to neutrality. Regarding the Martian rock, 15.1% of astrobiologists showed agreement, 44.6% disagreement and 40.3% neutrality. Among those who showed disagreement, they were also asked if it was a categorical disagreement or with some reluctance. In the first case there was 35.1% complete disagreement, but in the second only 11.1%. Possible reasons. As explained in The Conversation one of the authors of this study, Peter Vickers, possibly this greater agreement in the case of Mars has an explanation. And, although the planet’s biosignatures were calculated with indirect methods at interstellar distances, the rock from Mars could be analyzed directly by the Perseverance rover. in situ. Errors can also occur, but not as easily as with K2-18b. It is impossible to know. If there is something that all scientists agree on, it is that many of the characteristics that on Earth are usually considered biological They can also be the result of geological processes. Therefore, it is impossible to know for sure if there is extraterrestrial life only by analyzing these biosignatures. The data should always be read with caution. Only the discovery of a living organism would be conclusive in this regard. Let’s not get confused. Science is based on evidence, not opinions. When there is evidence of something, such as that vaccines save lives, there is no room for opinions. However, on more complex topics to study, such as those related to space, there may be opinions, which in turn are supported by evidence. That is precisely what C-SCOPE scientists have seen with this new study. We should not simplify. “Treating scientific opinion as pro or con runs the risk of oversimplification.” This is what we saw at the beginning of this text. The answer to whether there is extraterrestrial life cannot simply be a yes or no. There are many nuances that must be investigated and evidence that will surely evolve over time. Unfortunately, as Vickers also points out, “public debates often invoke scientific consensus.” Scientific consensus exists and is necessary, but individual opinions, as long as they are well founded, are just as useful. This is how science grows and is enriched. Based on data, questions and reviews. We should not trust a scientist who answers the question about life beyond Earth with a simple yes or no, because science is not that polarized. That, although it can sometimes frustrate us a little, is part of what makes it so fascinating.

In Spain we have glorified the long nap. In scientific studies they have a different opinion on the matter.

The siesta is, for many, a fundamental pillar of the Mediterranean lifestyle and an essential pleasure during the afternoon to be able to endure the rest of the day. However, scientific evidence has put this habit under the microscope, especially when naps last several hours and even give you time to dream several times. And the duration, frequency and especially age have a lot to say about the impact on health. The border of time. The current scientific consensus draws a fairly clear line between the classic power nap and the nap of putting on your pajamas and getting into bed for several hours. Because the barrier is marked precisely at the half hour mark, meaning that whoever passes it may begin to notice changes in their health. Here, a recent study from the University of Murcia analyzed to more than 3,000 adults in a Mediterranean environment to analyze the effect of naps. And the reality is that spending more than these 30 minutes was associated with having a higher BMI, a higher incidence of obesity and also being more likely to have a metabolic syndrome such as, for example, diabetes or hypertension. And there is more. When it comes to cardiovascular health, the reality is that the heart can suffer. Here the European Society of Cardiology presented In 2023, different data associated naps longer than 30 minutes with almost double the risk of developing atrial fibrillation. But also the American Heart Association took data who supported this point by pointing out that naps lasting longer than an hour increased the rate of cardiovascular disease by 1.82 times. The age factor. In this sense, one of the most important studies published is found in JAMA, that after following 1,338 older adults for 19 years and objectively measuring their sleep, they were able to see the effect it had. Here it was seen that sleeping more during the day, doing so more frequently or concentrating the nap in the morning was associated with with higher mortality from any cause. Specifically, each extra hour of daytime sleep increased the risk of mortality by 13%. There is much left to investigate. Among the studies that are currently available, no clear correlation has been found, that is, that someone who takes a three-hour nap a day should not have any problems. The only thing that is pointed out is that having the need to sleep excessively during the day can be a consequence of a poor night’s rest because there is a disease that is beginning to see the light, such as sleep apnea. You can take a nap. Although it may seem that we are demonizing the nap, the reality is that it has an important beneficial component when it comes to naps. less than 30 minutes. Here we are achieving an improvement in cognitive performance and it is also a way to recharge our energy a little for the rest of the day. But from here to actively planning a nap that can last for hours, there is a long way that should undoubtedly be avoided.

What did Nietzsche mean by “we contradict an opinion when in reality what we find unpleasant is the tone”

I’m not sure how to write this so as not to be unpleasant, but Nietzsche was right. Yeah, he had a weird mustachehe was loaded with opium and loved to take long walks in the Alps; but he was right. At least when it comes to one of his most apparently innocuous, but most radical ideas: that it often doesn’t matter if someone is right or wrong, that we make the decision to agree with them beforehand, that what matters most to us is the tone, the forms. The rest, although it doesn’t hurt to admit it, doesn’t matter. 150 years after Nietzsche, cognitive science has proven him right. What did Nietzsche mean…? In 1878, in the midst of a break with Wagner and Schopenhauer, Friedrich Nietzsche published ‘Human, too human‘. It was his first book of aphorisms and in it he abandons romantic aesthetics and sets out to find a new way of observing the world. In that book, the Austrian philosopher makes a complete x-ray of the psychological junk of human beings. “Opinions are born from passions,” he says in aphorism 637. “Convictions are more dangerous enemies of the truth than lies,” he writes in 483. But the one that interests us is 303. Where Nietzsche discovered confirmation bias. “Often, we contradict an opinion when in reality what we find unpleasant is only the tone in which it was expressed,” says that aphorism. And that sounds a lot like what modern cognitive science calls ‘confirmation bias‘: the tendency to search for, interpret and remember information in such a way that pre-existing beliefs, expectations or hypotheses are reinforced. First we form an idea from the tone of the person speaking to us and then we justify it. Simple, clean and perfectly confirmed by the evidence. Ultimately, what Nietzsche did is anticipate many of the ideas that Kahneman and Tversky They earned him the Nobel Prize. But that matters little, what matters is what we can learn. And, under that sullen and savage reputation, Nietzsche has a lot of useful ideas. This intuition, without going any further, has a direct and everyday application: when someone addresses us with a tone that we perceive as aggressive, condescending or arrogant, our brain activates defense mechanisms that prevent us from rationally processing the content. We do not evaluate what they tell us, we evaluate how they tell us. Reactanceconfirmation bias and post-hoc rationalization: the perfect combo to act automatically without paying attention to reasons or consequences. In the same way, Nietzschenian reflection helps us think about how we address others. And that is worth it.

Sleeping in on the weekend seems like the perfect solution to your tiredness. Your body has a very different opinion

Sleep eight hours a day religiously is for many a goal that they almost never manage to achieve, since the alarms sound too early and the days lengthen, accumulating a dream debt which we tried to settle on Saturday morning. But here the question is obligatory: are we achieving anything by sleeping 10 hours on Saturday? The answer. Here science has wanted to investigate the debate about whether doing this recovery sleep technique on weekends is useful or is a temporary patch. And the truth is that there are endless different options that mean we don’t have a ‘yes’ or a ‘no’. Cardiovascular shield. At first glance, science seems to agree with people who decide that the weekend is for sleeping, since several studies suggest that it is quite positive for our health. One of these analyzed more than 90,000 people and concluded that the group that accumulated more compensatory sleep on the weekend had a lower risk of developing heart disease. And more specifically, these people had up to 20% less risk of suffering from coronary heart disease. On the other hand, another study used data from the NHANES surveys carried out in 2018 and noticed an association between recovering hours of sleep and a lower prevalence of cardiovascular diseases, which is something that stands out especially in patients who slept less than 6 hours during the week. There is small print. In science there are contrary points, since researchers, when they affirm measurement methods and look beyond self-completed questionnaires, reality is more complex. Here is a study with 70,000 people who used accelerometers to objectively measure sleep threw cold water on previous evidence by pointing out that compensatory weekend sleep is not associated with lower mortality or fewer cardiovascular events. More alterations. Apart from all this, different scientific reviews point out that the evidence is heterogeneous, pointing out that sleeping more on the weekend does not always manage to correct problems such as insulin sensitivity, which is altered after previous days of sleep restriction. And it is known right now that biologically, lack of sleep triggers complex processes such as insulin resistancethe activity of the sympathetic nervous system and systemic inflammation. And all this cannot be fixed in a silly weekend of sleeping a few more hours, since a much longer sleep regulation would be needed to once again have an optimized biological system. Beyond the heart. Although we usually focus on the engine of our body, the reality is that there are effects much further than that. In the case of mental health, science suggests that weekend recovery carries a lower risk of depression. But other articles on health-related quality of life suggest that the “optimal” duration of recovery sleep is not the same for everyone, and can vary greatly depending on the sex and chronotype of each individual. The verdict. Right now science tells us that there is an association, but not a proven coincidence. In this way, trying to pay off your sleep debt on the weekend is undoubtedly better than continuing to sleep little seven days a week, but it is not a metabolic time machine. What you have to keep in mind is that the final effect will depend on how much deficit you carry during the week and how many hours you try to achieve, but in the end the medical advice that we should stick with is that the objective is to have consistency in daily rest so that it is as optimal as possible.

Toyota and Subaru have another opinion

Electrification in the automobile sector is taking with it one of the elements that has been with us practically all our lives: the manual transmission. For many people it is not a very serious problem, since an automatic car is actually more comfortable to drive. But for those who long for the sensations of a manual transmission, it marks the end of an era. Or not? Maybe is not completely lost. There are manufacturers that have been exploring the idea of ​​developing for some time. transmissions with a virtual manual shift in electric vehicles. Some of the manufacturers that have contributed the most in this direction have been firms like Toyota or Subaruwho seem unwilling to give up one of the driving experiences most valued by motoring enthusiasts (and by many other ordinary people who have driven all their lives). Is the virtual now the authentic? A few days ago, the people at CarBuzz echoed that Subaru had registered a patent in the United States for a fully simulated manual transmission system in electric cars. The design includes both an H-pattern shifter and a clutch pedal, although neither would be mechanically connected to anything. Instead, they use sensors that detect the position of each element and transmit that information to the vehicle’s computer, which adjusts the engine torque according to the selected “gear” and the pressure on the accelerator and clutch. Why is it relevant? Electric cars do without traditional transmissions because their engines deliver 100% of the torque from zero revolutions. This makes the gearboxes unnecessary from a technical point of view, but it also eliminates this element that has been with us forever and that endures as a sign of much more active control of the car. Manufacturers like Toyota and Subaru are convinced that there is a niche market willing to pay to recover that feeling, even if it is artificial. Toyota already has a working prototype. The idea is not new for the group. Toyota has been working on this concept for years and already has an operational prototype based on an electric Lexus UX 300e. According to InsideEVs, which could test it in 2023the experience ends up being surprisingly realistic. At the time, the vehicle featured simulated six-speed shifts, artificial engine sounds, and even replicated the characteristic jerk when shifting gears. In fact, from the middle they counted that the system allowed the car to “stall” if you did not press the clutch correctly and also simulated engine braking when downshifting. Best of all, the prototype allowed these types of functions to be activated and deactivated with a single switch, allowing the driver to choose between manual mode or conventional electric operation. What Subaru has come up with. Subaru’s patent goes a step further in this regard, as it incorporates a “hard start suppression device” that replicates the safety system of traditional manual cars, causing the vehicle to only start if the clutch pedal is fully depressed. Interestingly, the system is designed to activate manual mode by default every time the car is started, regardless of which mode it was left in previously. According to describe CarBuzz, this decision seems to seek to prevent the driver from forgetting which mode they left the vehicle in, although it is striking that manual mode is the default option. The connection between both brands. That Subaru patents a system practically identical to the prototype that Toyota already has running makes perfect sense, since Subaru is part of the Toyota group and collaborates closely with the brand in the development of electric vehicles, as demonstrated by the Subaru Solterra and its sister models. It is possible that the idea of ​​both manufacturers is to develop a sports model that has this type of virtual manual transmission systems. It does not mean that we see this system in all their vehicles, but in those with a more performance focus. More options on the way. Just like account CarBuzz, Hyundai and Kia have also taken the first step with eight-speed simulated transmission systems in models like the Ioniq 5N and the EV6 GT, although without a clutch pedal. On the other hand, Honda also offers eight fake “gears” in the new Prelude. However, none of those mentioned comes close to the level that Toyota or Subaru aspire to achieve with their systems. We will see if commercial models with this system finally arrive and if there is demand for them.

science has a different opinion

For a person with celiac diseasesocial life can be a real minefield. Cross contamination is a dangerous enemy that is present in the way food is prepared, but also in the kisses we have with other people. In this way, the question is obligatory: if my partner has eaten bread, pizza or pasta… Is it dangerous for us to kiss if I am celiac? To answer, luckily we have science on our side. Until now, people who have to stay away from gluten for serious medical reasons could be afraid to kiss if their partner had not rinsed their mouth or brushed their teeth before. But science is pretty transparent. in the preliminary study presented at Digestive Disease Week 2025. Their conclusion is quite clear: some gluten can be passed through a kiss between two people, but the amount is so small that it is very unlikely to have relevant clinical consequences. The study. To reach this conclusion, 20 non-celiac people who ate a food with a large amount of gluten were recruited. Immediately afterwards, they had to kiss their celiac partners, allowing the researchers to measure the concentration of gluten in the saliva that had passed from one boba to another. The results were quite clear: in 18 of the 20 couples, the levels in the recipient’s saliva were below the international “safe” threshold, which is 20 mg, and furthermore, none reported symptoms related to intolerance. Although if you drink a little water before kissing, this risk decreases even more. Why 20 mg. This threshold value is not something random, but rather it turns out to be defined by science itself. Here one of the reference studies comes into play, Catassi’s essay and collaborators published in American Journal of Clinical Nutritionwhich administered 10 or 50 mg of gluten daily to adults with treated celiac disease for 90 days. What was seen is that the daily exposure was clearly below that 10 mg range for the majority of patients. A later review in Alimentary Pharmacology & Therapeutics reached similar conclusions: the doses that are beginning to be worrying move in the order of tens of milligrams per day, especially if they are maintained over time, not in single isolated traces. In this way, an isolated kiss has the same concentration of gluten as foods that are categorized as safe. How is it possible that a kiss after eating a large amount of gluten-containing foods is not dangerous? This is the question we ask ourselves after reading these conclusions, and it has an answer, but in studies done on peanutsanother allergen. In this case it was seen that just after eating, the concentration of allergen in the mouth is really high. But after simple measures such as waiting a few minutes, drinking water or brushing your teeth, levels drop drastically. In this way, a kiss does not transfer food, but rather a fraction of a milliliter of saliva. And that saliva, minutes after eating, has already “cleaned” most of the protein that was inside. And this is valid for all allergies that are mediated by immunoglobulin E (which is responsible for generating the allergic response). There is a margin of safety. On a daily basis, people who are intolerable to gluten and who follow a very strict diet to avoid contamination, the truth is that they consume this allergen. Although in a very small quantity. This shows it a study who developed techniques to measure gluten immunogenic peptides (GIP) in urine and feces. The work showed that many people with celiac disease who follow a strict diet have small accidental exposures on a regular basis, the result of cross-contamination in modern life. However, the majority do not show clinical worsening or intestinal damage if these exposures are spontaneous and at very low doses. A kiss, in the worst case scenario, is exactly that: an isolated microdose exposure. The final verdict. What this new study provides is not a revolution, but a reassuring quantification of something that the consensus of experts already sensed. Even the main patient associations, such as the Celiac Disease Foundation or Coeliac UK, have been with a practical message for some time: the risk of kissing is low. The only common sense recommendation, which is still valid, is to avoid kissing right at the moment when the other person is eating gluten or has obvious remains of food in their mouth. You always have to wait a little for the saliva to take effect, but it doesn’t have to be a problem beyond this.

Chery trusted Spain to assault the European market without tariffs. Europe has another opinion

Europe, China and cars. A bomb that, for now, has resulted in the imposition of tariffs on the electric car. The European objective is that Chinese manufacturers invest in Europe if they want to sell their electric cars at the price that pleases them. Chery thought that Spain would be his gateway to the market of our continent. The European Commission believes that it is not enough. “It’s not a good model”. The definition is by the Executive Vice President of the Commission for Prosperity and Industrial Strategy, Stéphane Séjourné. The Frenchman expressed in these terms collected by The newspaperwhile ensuring that relations between China and Europe are “in the midst of nowhere.” What is about the model that Chery has implemented in Barcelona, ​​a factory where, at least for the moment, only cars that previously arrive mounted from China are completed. It is the easiest way to put the label Made in Spain to a product that, in reality, has very little of Spanish. DKD. Or, what is the same, Direct Knock Down. This is what the way of working is called that Chery employ in Barcelona. In summary, cars arrive in semi -ado containers and the only thing that is done in Spain is to finish marrying the last parts as if they were the four large groups of pieces of a puzzle that, in reality, is made up of thousands of them. The process is so advanced that, in fact, cars in Barcelona are not even painted. The intention, in the future, is to jump to the CKD (Complete Knock Down), in which the pieces do not arrive welded or painted but do produce entirely in China. The cars produced under this system are the Ebro that, although rescue the name of a Spanish brand, They are actually entirely Chinese. “Low quality”. In his statements, Séjourné, has insisted that “a factory on the outskirts of Barcelona in which a car occurs with all Chinese components generates Low quality jobs And it does not suppose any added value for the European industry. “And he emphasizes:” The solution does not go on to maintain tariffs, but neither by a factory in Barcelona in which cars are assembled with all Chinese components. “ Although hard, the words of the vice president of the commission are not new in the car market. In fact, Chery had already received Europe’s notice that, working in this way would not free him from tariffs to his electric cars. At the moment, the Omoda 5 and Jaecoo 7 They continue to arrive from China but as they have combustion engines they are not taxed with tariffs. The electric omoda 5, however, is punished with a fee that in the case of Chery reaches 21% (which adds to 10% base for all cars from China, electric and non -electric). It is no accident that the company has delayed its incorporation to the Catalan plant without the confirmation of taking out its cars through the doors of the free zone without being punished with tariffs. “In nobody’s land”. As we said, Séjourné pointed out that negotiations between Europe and China are stopped. In his day, Europe taxed tariffs on Chinese electric cars but left the door open to those who take combustion engines, both pure and plug -in hybrids. This was seen as a hand tended to negotiation. Not imposing tariffs on this type of cars has allowed Chinese brands to have taken advantage of the entrance door of countries where cheaper cars are bought, such as Spain. In fact, Chery herself with just six cars in the market (distributed between Ebro, Omoda and Jaecoo) They already add more than 19,800 units In the first eight months of the year. And only three of those six cars have been selling the full year. That open door to a negotiation seemed to consolidate a few months ago. In April it was confirmed that Europe and China seemed willing to reach some kind of agreement between the two countries. The last thing we have known since then have been these last statements. They are not the only. What Europe wants is that Chinese manufacturers invest in our continent and generate business here. To skip those tariffs, everything indicates that companies have to assemble their cars in our soil but also generate a local industry that generates value through the Component provision. This way of acting by Chinese manufacturers is not something exclusive that they do in Europe. Byd is used very similarly in Thailand. But European manufacturers are also used in the same way in those markets that are veiled with tariffs, as happens in Algeria. Country that, tired of these practices, has already warned Renault that they will have to invest more money.

According to NASA, there has only been one person injured by a meteorite. The Ottoman Empire has another opinion

It could be a trivial question: how many people have been injured by the impact of a meteorite? The official answer, the only documented by NASA, is one. Only one. His name was Ann Hodges. He was taking a nap on the couch of his house, and survived to tell it. However, the dusty files of the Ottoman Empire tell a different story. One that does not end with a great Moraton, but with a death. The interrupted nap of Ann Hodges. The probability that a rock rock falls is very small, but it is never zero. On November 30, 1954, Ann Hodges was sleeping on the sofa of his house in Alabama when an object of the size of a softball ball crossed the roof, bounced on a radio and hit it on the hip. The result: a considerable bruise and a legal dispute between Hodges and her homemade. Tired of media care and curious tourists, the woman ended up donating the meteorite to Alabama Natural History Museum In 1956, where it can still be visited. Two subsequent cases. From the interrupted nap of Ann Hodges there have been two doubtful cases. In 1992, a Uganda child said he was reached in the head by a small rock fragment. The Meteoritus rain existedbut the child suffered any damage. In 2016, a man died in India for the alleged impact of a meteorite. NASA It ended up determining that had not been a meteorite, but an explosion on land. A death in Ottoman archives. In 2020, a team of researchers diving in the state archives of Türkiye found something unexpected. Three manuscripts written in Turkish Ottoman described with chilling details An event occurred on August 22, 1888. The documents, which were official reports aimed at Sultan Abdul Hamid II, report that a “bright light accompanied by smoke” was followed, for about ten minutes, of meteorites that fell “like the rain” on a village of Sulaymaniyah, a region that today is part of Iraq. The consequences were tragic: “A man died and another was seriously injured and was paralyzed.” The texts also mention extensive damage to crops. No one knows where those rocks are. The documents mention that samples of the rocks were sent to the capital, but the researchers have not found them. Even so, it is the first report in the story, backed by three manuscripts, which states that the impact of a meteorite killed a man. The incident has gone unnoticed by more than a century by the idiomatic barrier and the little interest in reviewing historical archives of this type, but seems authentic. “Because these documents come from official government sources, we have no suspicion about their truthfulness,” the study concludes. Unlikely, but not impossible. Every day, about 44 tons of meteoritic material bombard the earthbut the vast majority disintegrates in the atmosphere. That a large enough fragment survives and, in addition, impacts a populated area and, to top it off, hit a person, it is statistically unlikely, but not impossible. Even so, it is not the meteorites that should worry, but our own garbage. Every day three large pieces of space garbage, such as dead satellites or rocket stages re -entering in the atmosphere. The majority burns or falls into the ocean, but luck is not eternal. With the new megaconstellations, the resentments will multiply. “Sooner or later we will have bad luck and someone will be injured by the fall of space garbage,” warns the astrophysic Jonathan McDowell.

The United States is convinced that the Chinese army already uses its chips for ia. Nvidia has a different opinion

The CEO of Nvidia, Jensen Huang, recently granted An interview to the CNN medium, where he could speak without capujos about the current context of his company, about Nvidia’s position in the AI racethe benefits of this technology, and other relevant topics of current affairs. In addition, he has also provided his opinion about The commercial war with China and restrictions, as well as the possible use of American technology in Chinese military terrain. Chips for the Chinese army. The United States has shown concerns in the past about whether advanced Nvidia chips would be used by the Chinese army. Those concerns gave rise to The restrictions of chips A100 and H100. Despite this, There are indications that the chips would also be reaching the Chinese army. Nvidia is not worried. Huang It has subtracted importance To Washington’s concerns about the military use of its artificial intelligence chips by China, arguing that the Chinese army cannot depend on American technology that can end up being restricted at any time. Their statements come while the company promises to resume sales of Its H20 processors to the Chinese market and days after meeting with President Donald Trump in the White House. Huang’s position against Washington. In the interview, the manager defended that “we do not have to worry” about the military use of American technology in China, since “they simply cannot trust it.” His argument is that Beijing will avoid depending on US components due to the risk of future limitations. Huang added that China already has “a lot of computing capacity” and does not need Nvidia chips to develop its military capabilities. The restriccions have hit Nvidia. US administrations have maintained export controls on the most advanced semiconductors for fear of strengthening Chinese military capacities. These measures, applied in a bipartisan manner, have cost Nvidia billions of dollars in potential revenues. According to the company, restrictions made them lose approximately about 15,000 million dollars in sales After the latest restrictions imposed by the Trump administration to prohibit their chips to China. The company affirms which also had to amortize 5,500 million in inventory. Between Washington and Beijing. It is clear that the company is making extraordinary efforts to maintain a balance between Washington and Beijing. His CEO openly criticizes control policies, arguing that They are counterproductive For American technological leadership. His thesis is that for the United States to maintain its dominant position in AI, American technology must be available globally, included in China, where half of the world’s developers are located. American senators They have warned him specifically that avoids meeting with companies linked to the Chinese army or intelligence organizations during your visit to Beijing. Meanwhile, Nvidia faces Huawei’s growing competition and other Chinese chip manufacturers, although the country’s technology companies continue to demand their processors due to their platform CUDA. And now what. Nvidia has announced that you will request licenses for Resume Sales of the H20 Chip to Chinawith the US government ensuring that it will grant them soon. The company has also developed a new processor specifically designed to comply with current regulations: the RTX Pro GPU, which is part of the architecture Blackwell and is completely adapted to export controls. China represents 13% of the total income of Nvidiaabout 17,000 million dollars, which explains why Huang maintains its favorable speech towards the Chinese market while sailing among the geopolitical pressures of both countries. The H20 chip had been developed specifically for the Chinese market after the restrictions of the late 2023, becoming the most powerful product legally available until its effective prohibition in April.

Japan believes that samurai crabs keep the souls of the fallen warriors. Science has another opinion

See faces on a wall Or in any daily object it is not a symptom of madness. This phenomenon has a name: Pareidoliaand that is what makes us perceive as something recognizable a way that initially has no pattern. If we put effort, we can See recognizable ways In almost anything, even in the shell of a crab. And, if not, they tell the Japanese and their samurai crabs that keep the spirit of the fallen warriors in a battle. Or so the legend says. Heikegani. The Japanese heikesis They are a family of crabs that inhabit, mainly, in Japan. They have been found in some other western Pacific areas, but where they are more numerous in the Japanese country and, specifically, in the inner sea. They live in shallow waters in which they camouflage and find food, and could be normal crabs if not for their shell. Because, if in the photos that accompany this article you see a Miegu mask traditionally used by Samurais of feudal Japan At the top of the crab, you should know that you are not the only one. And, how could it be otherwise, the Japanese folklore It has an explanation for this phenomenon. The legend. At the end of the 12th century, the Genji clan and the Heike clan fought in a bloody Battle in the bay dan-no -urain the inner sea of ​​Japan. The Heike had ruled for decades, but the Genji wanted power and were more numerous. They won the battle and established a warrior government in Japan, a Shogunate which lasted for seven centuries while their enemies fell into the bay Under steel Or, directly, drowned. It is said that the spirits of those heike warriors who drowning were reincarnated in living beings who caught more by hand, crabs, and Thus they were born These Heikegani. Samurai crabs changed their shells, adopting the patterns of the faces and masks of the fallen warriors, and culturally they are a symbol of resistance and loyalty. Antinatural selection. It is a beautiful story, but unfortunately it is nothing more than something belonging to the rich Japanese folklore. Now, it is evident that these ‘samurai crabs’ have something special and, certainly, their shell is very similar to the masks. The explanation? Well, according to Carl Sagan -Yes, the famous astronomer– The Heikegani were created from the Artificial selection. They are edible and fish by the premises, but in the process of selecting individuals, the fishermen kept the “normal” crabs and returned to the water those who showed that pattern in the shell. It was a sign of respect for the heike warriors, and Sagan popularized the idea that these selected crabs were reproduced, perpetuating that curious design. Simple coincidence? However, there are those who doubt this story and offers an alternative vision. Joel Martin It is a biologist associated with the Department of invertebrate Zoology in the Natural History Museum of Los Angeles and has dedicated its career to investigate the evolution of crustaceans and other invertebrates. One of his most famous works is the job On the samurai crab published in 1993- in it, it states that humans practically did not consume Heikegani, so the selective pressure would be minimal or non-existent. Functionality. Your explanation? That these facial patterns similar to masks are due to own functional anatomy of the crabsince they represent the muscle insertion points Very similar to crabs that we see in other parts of the world. If we see the crab backwards (they are more ugly than a refrigerator from behind), it has all the meaning and the researcher points out that this interpretation we make of their faces is simply one more example of pareidolia. Martin may be right, but I definitely stay with the version that Samurai crabs are there watching the battle spirits in the bay in which Japan changed forever.
