The largest nuclear fusion project on the planet has survived the setbacks. This is the date on which Iter should be ready

by

2024 was a difficult year for ITER (International Thermonuclear Experctor reactor). This experimental reactor of nuclear fusion It is being built in the French town of Cadarache by an international consortium Led by the European Union. Although it was conceived in 2006 and the project was officially launched in 2007, the beginning of the assembly of this titanic machine did not start until 2020. The initial itinerary Proposed by Eurofusion, which is the institution that is responsible for promoting and supporting the scientific research necessary to bring to fruition the European Nuclear Fusion Plan, established that in 2025 the assembly of this machine would end. However, that same year another crucial milestone would arrive: the first tests with plasma would start. Three years later, in 2028, Iter engineers would begin the low power with hydrogen and helium, and in 2032 the first high -power experiments would arrive with these two gases. Finally, in 2035, Iter would be able to undertake high power tests with deuterium and tritium. And in 2040 this experimental reactor would demonstrate the energy profitability of nuclear fusion. Finally this will not happen like this. In 2022 the French Nuclear Safety Authority (ASN) identified several irregularities of a strictly technical nature in Vacuum Chamber sectorswhich caused the Iter organization to react as it should do so: constituting a working group to address the complementary requests of the ASN and advance with the reactor assembly Tokamak. Iter’s technical challenges are unpublished Assembling a machine as complex as it is it is not easy. The vacuum chamber weighs 8,000 tons, is made of stainless steel and boron and must remain hermetically sealed. Its assembly has forced engineers to deal with extraordinarily strict local tolerances of 0.1%, and, in addition, the camera has a very complicated shape and uses plates with thicknesses up to 60 mm. To solve the assembly the technicians have had to resort to state -of -the -art technologies, such as the Electron Beam Weldingwhich is welding using an electron beam, or The design of AI models specifically conceived to identify defects in the welds of the camera. The Covid-19 Pandemia that raised very crudely during the 2020s and 2021, and, on the other hand, the technical challenges derived from the completely unpublished nature of much of the components that need to be tuning so that Iter arrives in fruition have caused that The main milestones of this project are delayed. Nevertheless, The current updated itinerary proposes several important dates that interest us know. In 2039 Iter will be able to undertake high power tests with deuterium and tritium In 2034 the first experiments will be carried out in the reactor; In 2036 the magnetic system responsible for confinement of plasma to maximum power will be tested; And finally, in 2039 Iter will be able to undertake high power tests with deuterium and tritium. Initially this last milestone was going to arrive in 2035. Whatever it is during the last year the Iter assembly has advanced at a good pace. In the cover image of this article we can see two of the titanic sectors of the vacuum chamber, although, in my opinion, one of The milestones that this project has achieved This year It was consolidated in May. The superconductor magnets placed on the outside of the vacuum chamber of this nuclear fusion reactor have the responsibility of generating the magnetic field necessary to confine plasma inside. They are also responsible for controlling and stabilizing it. These magnets weigh 10,000 tons and are manufactured in an alloy of niobio and tin, or niobio and titanium, which acquires the superconductivity when cools with a supercritical helium until reaching a temperature of -269 ºC. This requirement justifies the need to put a powerful cooling system like the one that has devised Europe for Iter. In the construction of this experimental nuclear fusion reactor, the US, Russia, China, India, South Korea, Japan and the United Kingdom, but the cryogenization plant have been commissioned by Fusion for Energy (F4E), the organization of the European Union that coordinates the contribution of Europe to the development of Iter, the French company Air Liquide and technical integrated technicians in the Iter structure. Superconductor magnets acquire superconductivity when they reach a temperature of -269 ºC This extreme refrigeration installation will be responsible for supplying liquid helium to 4.5 Kelvin (-269 ° C) to superconductor magnets and criobombs, and also gaseous helium at 80 Kelvin (-193 ºC) to thermal shields. Creobombs are empty ultraalt devices that are responsible for eliminating gases inside the vacuum chamber. To do it They must work at an extremely low temperature. And, on the other hand, the thermal shields are responsible for protecting some critical elements of the reactor, such as superconductor magnets, the heat that emits the confined plasma inside the vacuum chamber. Iter’s cryogenic plant has an area similar to that of a football field (just over 7,100 m²) and contains several 26 -meter high storage tanks. These figures help us intuit how enormous this critical installation is. As we have just verified, without it the nuclear fusion would be absolutely impossible. This Grigory Kouzmenko statementF4E manager, invites us to tie Iter’s future with a reasonable optimism: “We have entered the most exciting phase of the project, in which all the efforts of previous years finally are specified and we can benefit from the collaboration based on the confidence between all the parties.” Image | Fusion for Energy More information | ITER In Xataka | From today Spain has the key to nuclear fusion: Granada’s particle accelerator is already a reality

The trend that divides pediatricians and parents

by

When little Schizandra, daughter of Dariya Quenneville, turned six months and was time to try solids, there was no apple puree or banana porridge. Instead: raw egg yolk and chicken liver puree. Sardines, butter and even bone broth ice cream came later. A quite unusual diet for a baby, which is gradually being part of a growing phenomenon: “carnivores”. A booming trend. In a report for The Wall Street Journalmore and more mothers document how their babies suck bone marrow or bite ribs, inspired by doctors and Influencers that promote the carnivorous diet In YouTube channels With hundreds of thousands of followers. In Facebook groups with names such as Carnivore Motherhoodtips on how to prepare “pallets” of bone broth or serve the tongue and heart of beef are shared to the little ones. For Quenneville, who lives in Ontario and teaches survival techniques, thus feeding his daughter makes sense: “I think that butter fat and meat helps my baby to sleep better.” Another mother, Lorraine Bonkowski, a Michigan dietitian, started being skeptical, but after watching videos on the Internet ended up convinced. Today he gives his adopted daughter Isabella bone broth in a bottle and leaves her groove chops. “If it makes sense for adults, why not for children?” He asks. In Tennessee, nurse Neisha Salas-Berry and her husband, doctor Ken Berry, are an influential couple in this movement. She says her children Bonnie and Beckett learned from babies that “first meat, before anything else.” On family trips, the little ones eat chicharrones that Beckett called “cookies” and carnivorous bars that cost $ 95 a box. “My daughter calls them sweet meat”, He told WSJ. Experts have something to say. The introduction of meat in child feeding is not, in itself, eccentricity. Both the American Academy of Pediatrics and the World Health Organization They make it clear: From six months, babies must incorporate foods rich in iron and zinc. The flesh, for its natural contribution of both minerals, becomes one of the main allies at this stage. However, as the pediatrician Mark Corkins, from the University of Tennessee, has warned, In statements to WSJ: “Babies need vitamin C and fiber for proper development of connective tissue and intestinal microbioma, nutrients that shine due to their absence in strict carnivorous diets.” A great preparation behind. On the practical level, According to Healthlinethe meat must be cooked a lot – never raw or little done – and sausages, sausages or beicon should be avoided due to their excess additives. The meat provides not only Hemo Iron – the easiest to absorb – but also high quality proteins, vitamin B12 and zinc, all crucial for growth. The Specialized Solid Starts portal, dedicated to child feeding, even offers detailed guides to serve ribs either fillets To babies: from using bones as bite at six months to offering well -cooked meat strips as part of the Baby-Led Weaning. Of course, always eliminating loose pieces of fat or cartilage and under strict supervision for the risk of choking. The other option, totally opposite. While meat can be a nutritional ally, there are families that opt ​​on the contrary. Vegetarianism and veganism are also booming in parenting, According to eldiario.es. The document adds that these diets require special care to avoid energy and nutrient deficits. As the country explainedup to six months the food is identical for all babies: breast milk or formula. In the case of vegan families there are regulated children’s formulas based on soy or rice, but they should never be replaced by commercial vegetable drinks, which do not provide the necessary nutrients. From six months, the protein comes from legumes, nuts and seeds – always crushed or cream – as well as soy derivatives such as tofu or tempeh. Of course, all specialists agree on one point: vegan babies should receive a vitamin B12 supplement from the introduction of solids. Neither so much, so bald. Between chop as almost exclusive food and strictly vegan diet, most experts recommend an intermediate path: variety and balance. Professor Steven Abrams, from the Faculty of Medicine Dell of the University of Texas, remembered at the Wall Street Journal That meat is valuable because it brings iron and zinc in an easily absorbable way, but insisted that young children also need fiber, antioxidants and polyphenols that are only in fruits and vegetables. “The restrictive diets in young children are not the way to follow,” he warned. In Spain, fashion has not yet arrived, but the practice is well settled: from six months, babies begin to try white meats in small quantities, always next to vegetables, According to the Spanish Pediatrics Association. The Mediterranean tradition reinforces the idea: the flesh not as the main dish, but in small portions, as garrison, and accompanied by cereals, vegetables and fruits. The debate is served. Between babies that bite lamb bones and others that begin with lentil puree, child feeding has become a field of cultural, scientific and even ideological debate. While parents claim chuleton as “biologically appropriate,” others plan vegan diets with nutrient supplements and tables. The truth is that, as official guides conclude both in the US, and in Spain, the fundamental thing is not that the first bite is meat or carrot, but that the child receives a varied, safe and adapted diet to their growth needs.

He was deported to China after co -founding NASA’s JPL. Now China has made one of his ideas come true: flying wind turbines

by

In the mid -twentieth century, the United States made a decision that later A high position of the Navy described as “the most stupid thing that this country has ever done.” Qian Xesenan indisputable genius of aeronautical engineering, co -founder of the prestigious JPL laboratory of NASA, and a key figure in the development of American coheteria, was deported to China in 1955 accused of communist sympathies in full witch hunt. Qian, welcomed as a hero in his homeland, became the father of the space program and the development of Balistic missiles in China. Decades later, a new generation of Chinese engineers, heirs of the scientific ecosystem that helped build, has broken a world record with a technology that pursues an old ambition of Qian Xesen: wind turbines that fly like zepelins to harvest the energy of great altitude winds. A Zepelin anchored to ground to generate electricity On October 10, in the heavens of Jingmen, province of Hubei, a 23 -meter long aerostate with a leadable appearance rose to 500 meters high. It was not a transport or surveillance vehicle, but The S500, a floating wind energy system That, at that altitude, began to generate more than 50 kilowatts of power. With this flight, China not only launched an innovative project, but sprayed two world records that until now He held an American MIT research team: The one with the highest flight altitude for such a turbine (the previous one was 297 meters) and the one with the highest power generated (compared to the previous 30). The concept, developed by the Sawes company In collaboration with the University of Tsinghua and the Chinese Academy of Sciences, it is as elegant as complex. The system uses A member of helium filling to raise a wind turbine to altitudes where the wind is much stronger and more constant than on the surface. The electricity that generates is transmitted to a station on land through the same high strength cable that anchors the structure. The advantage of this design is clear: the energy that can be extracted from the wind is proportional to the cube of its speed; already hundreds of meters high, Winds are not only faster, but also more stablesignificantly reducing the intermittency that it lills to the terrestrial wind farms. According to developer calculations, wind resources in the stratosphere on a region like Hami, in Xinjiang, are 40 times higher than those of the surface. Of emergency situations to the generation at network scale The S500 and its successor, the S1000 of 100 kW Proven for the first time in Januarywere developed for emergency rescues, urban security and places of difficult topography. In case of earthquake or flood, the system can be deployed rapidly to provide energy and communications in the disaster area. But Sawes’s ambitions go much further. The company He just finished assembly The following model on its road map: the S1500, designed to operate 1,500 meters of altituderepresents a jumping of the capacity in capacity, with a power of generation of 1 megavatio. It is proof that technology not only looks for niches such as emergency response, but aspires to become a renewable energy source at an electricity scale. To achieve this power, the S1500 integrates a complex system of 12 generators that operate simultaneously inside its central duct. The key for such a powerful system to fly is material engineering: generators are manufactured in carbon fiber To minimize the weight, maintaining the complete structure below a ton. Like his little brother, energy becomes electricity in the airship itself and low to land through an anchor -integrated cable. With this design, Sawes has attracted the support of important investment funds and contracts that already exceed 500 million yuan (about 64 million euros). The company has opened an assembly plant In Yueyang. The story of Qian Xesen is one of the greatest anecdotes about the unforeseen consequences of fear policy. As you tell Los Angeles Timesthe man who interrogated Wernher Von Braun and laid the basis of the JPL was separated and returned to a country that, at that time, had a much lower scientific development. He took care of changing that, and now his heirs are materializing some of his ideas in his native country.

28 pages of theories about gioconda and geodynamics

Change the image of A legendary brand It is a meticulous and risky process: it is played with the possible rejection of the public, accustomed to logos, typefaces and styles with which it already identifies. That is why he rebranding From Pepsi in 2008, absolutely radical and unexpected, it was not devoid of controversy. And the most notorious part of that controversy was carried by the 28 -page document in which the agency contracted explained the reason for the change. The logo of the past. Pepsi’s logo is one of those who more changes have experienced in history: even before being called Pepsi, when the company was Brad’s Drink between 1893 and 1898. From there, All types of variants: Until 1962, the original Pepsi-Cola logo went through seven versions, all with a calligraphic style and Vintage. In 1951 the bottle sheet appeared that would no longer abandon, in one way or another, to the logo, with the patriotic colors of the American flag (they were the times after World War II). From the 60s, the logo was modernized, the brand became Pepsi and relief details were introduced into the logo. The logo of the future. In 2008, Pepsi was in his moment of popularity: ads such as Britney Spears, Pink and Beyoncé versioning Queenand had an impact on undisputed youth aesthetics. However, the logo rebranding generated A remarkable controversy For the radical change in the design of the iconic circle with the red, white and blue stripes, which ceased to be parallel. In addition, it cost a million dollars, which The Arnell Group agency was pocketed. The idea that the logo remembered an overweight person, a lethal association for a highly sugary drink like Pepsi came to circulate. But what ended up rounding the controversy was the filtration in Reddit, in 2009, of An internal use document in which Arnell explained inspiration after change. And delirium began. The Aúrea proportion. The document starts more or less reasonably, although some reflections on the relationship between the Pepsi logo and The golden proportion (It is said that the long history of the logo converges in this new symbol). Then, compare different ideas for that new logo with smiling faces, gestures that suggest different positions of the lines and why the finally chosen (which, let’s not forget, left aside the classic parallel lines of the soda sheet that remembered a flag waving) is the best option. Everything honors the fantastic document title: “Breathtaking Design Strategy”, or “Impressive design strategy” (capital letters are them, of course). The thing gets hard. It is then that concepts such as “emotional forces shape the Gestalt of brand identity”, relating notions of optimism and joy, connecting the brand to youth and energy. We are told (completely seriously) of the Pepsi planet and the Pepsi galaxy, all encompassed in the Pepsi universe. And we arrive at The authentic inspiration of the new logo: The geodinamo of the earth, A natural electric generator in fluid motion that generates and sustains the earth’s magnetic field. Well, that and the Mona Lisa, of course, with which parallels related to the golden proportions are drawn (also the man of Vutruvio is taken for a walk). But was it true? The astonishment of the design industry (and that of refreshing drinks) before the sales document came to the table The idea that it was actually falseand was part of the Pepsi Publicitaia campaign to talk about change, something that was never denied (or confirmed). In any case, in 2023 the company would return to a logo more classic and less risky. Interestingly, in a nostalgic turn of these times, with their electric colors and their aggressive and analog lines, he remembers not the two thousands who really were, but to those who believe they were.

We have a big problem with plastic. This caterpillar can help us devouring a bag in 24 hours

by

The global plastic crisis, a problem that It takes centuries to degradeI could find an unexpected ally in the world of insects. A team of scientists He has revealed how the caterpillars of the wax worm (Galleria Mellonella) are able to devour and metabolize polyethylene, The most common plastic in the worldat an amazing speed. However, they have a deadly cost for them. A decomposition that is not perfect. The investigation, presented at the Annual Conference of the Experimental Biology Societyreveals that these caterpillars, nicknamed “plastivorous”, not only chew the plastic, but that they decompose metabolically and make it an body fat in a matter of days. The most shocking data: some 2,000 caterpillars can end a standard polyethylene bag in just 24 hours. The problem of the plastic diet. Polyethylene is the plastic that we find in purchase bags, containers and endless daily use products. His chemical resistance makes it incredibly durable and, therefore, A persistent contaminant. The finding that a living being can decompose it naturally opens a Revolutionary door for waste management. However, the solution is not as simple as let out millions of caterpillars in landfills. Dr. Bryan Cassone, professor at the University of Brandon (Canada) and project leader, explains the great inconvenience: an exclusive plastic diet is deadly for worms. “They do not survive more than a few days with a plastic diet and lose a considerable mass,” says Cassone. It is as if a human swells with fat. The process is similar to that of a human consuming excess fat: The caterpillars turn the plastic into lipids that accumulate in their adipose tissue, but without the necessary nutrients to survive. It is not the first time that this possibility is explored. Given the seriousness of this problem, science does not cease in its attempt to find a solution to disintegrate the plastic we generate. Thus, in 2022 a group of Australian researchers They verified the ability of the ‘super worms’ to devour polystyrene thanks to an enzyme they had in their metabolism. But these same wax worms, object of this study, also They were already protagonists of an investigation where the capacity they had to decompose the plastic was proven. This study has taken a step further to perfectly understand its processing system and the repercussions it can have. Towards a sustainable solution: supplements and bioengineering. Although the fact that the accumulation of fat is an obstacle to research, scientists have turned this fascinating biological process into a viable solution already a large scale for pollution and for this they point to two main roads: create a mixed diet and replicate the process in the laboratory. Create a mixed diet. Scientists are experiencing with “co-supplement”, such as sugars and other stimulants, to mix with polyethylene. The goal is to formulate a feed that not only keeps the caterpillars alive, but to optimize their ability to degrade plastic, creating a circular economy system where waste becomes food. Replicate the process in the laboratory. The second way is even more ambitious. It consists of thoroughly studying biological mechanisms and intestinal microbiome of caterpillars to identify enzymes and bacteria responsible for the decomposition of plastic. If they get it, they could replicate this process of “biodegradation” in an artificial way and industrial scale, without the need to raise insects. And right now there are a lot of daily products that have been generated thanks to the use of bacteria, fungi or enzymes. In this way, the fact of extrapolating this process to the industry can be the most intelligent to control the management of plastics. From garbage to the plate. As if solving one of the biggest environmental problems were not enough, this research could have a positive and unexpected economic impact. The massive breeding of wax worms would generate a huge amount of insect biomass. According to Dr. Cassone, these worms could become a very nutritious food source for aquaculture. In this way, a waste as problematic as plastic could be revalued to enter a new value chain, contributing to the food industry.

The Xpeng CEO is clear about the future apocalyptic of Chinese cars

by

China is following a very clear strategy with its cars: flood Europe. And is doing it with both factories on the continent and Large ships that bring thousands of cars from China. Are Battery leaders and The electric car is its avant -gardebut we must not forget Your combustion models. There are more and more models And there are those who think that this wild competition can be what leads to the failure of many companies. To the point that only a handful of them will be short -term. Specifically … five. At least, according to the CEO of The promising xpeng. Spearheads. The proper names of the Chinese car are, now, well known. There are brands like Byd, Omoda either Mg that are increasingly seen in European streets. They are following strategies to Live with big fish In a very competitive market, expanding dealer networks, manufacturing in Europestriving to Understand the European user and associating with brands like Stellantis To create strategic relationships. To those that are already here you can add other proper names of great weight, such as a Xiaomi whose models are awakening so much interest that the brand has turned its main factory into A kind of amusement park. Increasingly. There are more that they have a smaller portion of the cake at the moment, but they have ambition. Xpeng landed in Spain in 2024 And it has been reaching other markets such as the United Kingdom. Its intention is to be present in 60 countries by the end of this year, concessionaires included, and there are still other names that are yet to come. Chery (owner of Ebro, Omoda and Jaecoo), is preparing the landing of a new brand, LEPASand outside the automotive segment, we have brands like Dreame (manufacturers of vacuum cleaners and Pool cleaning robots) that too They have interest In this market with the aim of competing … against the Bugatti Veyron. Only five will remain. And in this panorama in which there are more and more brands of Chinese cars, either for having many models or because they get into the car due to the government impulse, a controversial statement of he Xiaopeng enters. This is the CEO of the aforementioned Xpeng and, in a recent Pódcast, commented that the Chinese automotive sector has entered a elimination phase. Their comments are radical, stating that “no Chinese manufacturer is safe from a elimination round that will reach its end in five years and in which only five brands will remain.” The reasons are the same as not so much They hit the solar panel industry in China. After flood West With its technology, A bestial price war caused sellers to have to operate at losses and do the logical: manufacture less. There are brands like Byd that were profitable, but others depend on reaching a certain scale to survive and there are already analysts that estimate that, although state aid They promoted initial sales, withdrawal of incentives to consumers will impact a very fragmented market. It is not a crazy idea. Alixpartners is a consultant who coincides with the predictions of He Xiaopeng, pointing That the number of viable brands of electric and hybrids will exceed the current 129 to just 15 from 2030, with only a few giants dominating the market. It is something that would take brands like children, which has sought to differentiate (even creating mobiles to complete the experience of their cars), but has suffered financial and capacity problems. And you don’t have to go to China to be catastrophic. Ola Källenius is Mercedes-Benz’s CEO already described last year The current market as “a Darwinian price war” in which many of the current actors will disappear in five years. The Keys of analysts for a brand to survive? Manufacturing capacity, scale to other markets and battery leadership.

Now we are in the phase of ingesting “30 plants a week”

by

For years, the public health message seemed clear: “five a day.” Five rations of fruits and vegetables were enough to take care of the body, although it was not always easy to fulfill it. The Zoe Williams columnist He remembered in his column for The Guardian That, when he took a food newspaper for a magazine, he discovered that in a week he had only eaten a vegetable, thanks to a hidden spinach sheet under a fried egg. Eating five daily rations was already a challenge for those who hated tomatoes or fruit. So when a new rule appeared – not five portions, but 30 plants other than week – the feeling was to be in front of an impossible challenge. 30 weekly plants? The idea is not to eat thirty giant salads. The “30 plan” consists in adding throughout the week 30 different plant foods: fruits, vegetables, legumes, nuts, seeds, whole grains, herbs and spices. Even coffee, tea or olive oil tell, although just like a quarterfinal, According to BBC. A report at The Conversation They explained that the concept comes from American Gut Projecta massive 2018 study with more than 10,000 participants in the US, United Kingdom and Australia. The researchers observed that those who consumed 30 or more different plants each week had a much more diverse intestinal microbiome than those that barely reached ten. From there came the magical figure. The color palette on your plate. The variety of colors not only makes a dish more attractive: it also fulfills a function in intestinal health. A more varied microbiome is associated with less risk of chronic diseases, better immunity and even a better mood. Dietitian Catherine Rabess has summarized in Women’s Health: “The combination of 30 plants other than week and 30g fiber daily is the golden ticket to revolutionize intestinal health.” In addition, the different colors and types of plants contain polyphenols, antioxidant and anti -inflammatory plant compounds that act as “intestine bodyguards.” Are we facing one more fashion? Scientific evidence supports the benefit of plant diversity. But it is also true that following the classic recommendations – five rations per day, whole grains, less red and out -of -process meat – already improves intestinal health, According to The Conversation. In other words: you don’t have to become obsessed with the 30th figure. Even small and sustainable changes have an impact. The challenge, in addition, is not the same for everyone. Buy 30 different varieties each week can be expensive and demand planning, storage space and time to cook. As have warned in the same medium You can even accentuate inequalities: not all families have resources, space or time to organize such a diverse pantry. That is why it is suggested to resort to canned, frozen or mixtures (such as vegetables or varied berries) to lower and facilitate the task, As pointed out in BBC. Beyond the diet. Despite what promulgates this new way of feeding, the intestine not only depends on what we eat. Sleep well, move daily, practice mindfulness or simply chew more slowly They are habits that also improve digestive health. In addition to avoiding Ultraprocessreduce alcohol and add fermented (kefir, yogurt, kimchi) and natural prebiotics (garlic, artichoke, nuts) still reinforces plus positive effects. A possible challenge. Zoe Williams ironized in his column With that, if today the challenge are 30 plants, tomorrow someone will ask for 60, and we will end up looking for ortigas. However, as dietitians and doctors point out in BBC and Women’s Healthreaching 30 is not so impossible: an oatmeal with cinnamon and nuts, a salad with chickpeas, an integral paste with spinach and basil, a mid -afternoon coffee and an ounce of black chocolate … and the points are already accumulated. The challenge of the 30 weekly plants does not intend to replace the classic guides, but to take a motivating turn: instead of talking about restrictions, talking about adding. Not everyone may achieve 30, but point at 20 or 25 already makes a difference. As The conversation concludes: “The important thing is not perfection, but sustainable changes.” Image | Pexels Xataka | The Spanish cherry had been dreaming of a stage that has just come true: open the doors of China

That Mount Fuji erupts would be catastrophic, so the Government of Japan has used AI to warn the population

by

The Japanese government has published a video created with artificial intelligence that shows the devastating consequences that would have an eruption of the Mount Fuji For the 20 million inhabitants of Tokyo. The video, disseminated last Sunday by the Disaster Prevention Division of the Tokyo Metropolitan Government, is part of a strategy to prepare the population before a natural catastrophe that, although it is not imminent, is possible. What does the video show. The simulation starts with a woman in a crowded street that receives an alert on her mobile informing her that the volcano has erupted. “The moment can come without prior notice,” warns the narrative before showing huge columns of smoke leaving the Fuji. The images generated by AI show how volcanic ash would arrive in Tokyo in just two hours, covering buildings and vehicles, and plunging the capital in the dark even during the day. Why now. Japan is in the Fire belt Del Pacífico, an area of ​​intense seismic and volcanic activity. The country houses 111 of the approximately 1,500 active volcanoes in the world. Mount Fuji, who for centuries erupted every 30 years approximately, He has been asleep since the known as Hoei eruption of 1707. The authorities have intensified the alert tone in the last year, especially after warning in January that there is 80% probability that A severe earthquake hits The Nankai pit region in the next 30 years. The economic and social impact. According to Official estimatesa large -scale rash would produce 1.7 billion cubic meters of volcanic ash, of which about 490 million would accumulate on roads, buildings and other surfaces. Economic losses could reach 2.5 billion yen (about 14,200 million euros). The ash would cause the collapse of wooden buildings with little load capacity, paralyze rail transport, cut the electricity supply and hinder the distribution of essential foods and products. Reactions found. We have had the reactions of all kinds. While some users in networks They have expressed His concern: “The idea that volcanic ash causes chaos in the transport of Tokyo’s metropolitan area is terrifying,” others have criticized the approach for which the government has opted, considering it as alarmist. “It tends to be used to stir a feeling of crisis and fear”, commented Another user. Practical preparation. The Government recommends to residents of areas near the Fuji maintain essential supplies for two weeks. The simulation includes a family scenes preparing pantries with canned food and first aid kit. However, some citizens indicate the practical difficulties of these measures, especially during Japanese summers, when temperatures reach Suffocating levels and an electric cut would be especially problematic.

China already has one of the most advanced observatories on the planet to hunt the most elusive particle that exists

by

Neutrinos are The most elusive particles of nature. They were first described from a theoretical point of view in 1930 by Austrian physicist Wolfgang Ernst Pauli, one of the parents of Quantum physics (We owe, among other contributions, known as exclusion principle). However, its experimental discovery took place two and a half decades later, in 1956. We owe it to American physicists Frederick Reines and Clyde Cowan. There is a forceful reason that explains why these particles are so difficult to detect: They barely interact with ordinary matter. In addition, its mass is very tiny, its electric charge is neutral and are not influenced by strong nuclear interaction or electromagnetic force, although due to gravity and weak nuclear interaction. There is no doubt that they are very special particles. Scientists often illustrate how difficult it is to capture a neutrino explaining that every second trillion of these particles go through both the earth and us without colliding with any other particle. You can also illustrate how elusive that they are using quantum mechanics, which ensures that it would be necessary to manufacture a lead plate with a light year thickness to ensure that half of the neutrinos that go through it collide with the particles of the lead block. The Jiangmen Observatory is ready to hunt neutrinos Despite how elusive neutrinos are, we have several observatories that are able to detect them. One of them is The Japanese Super-Kamiokande. This installation is located in Hida, a city located in the central area of ​​Honshu, the largest island in the Japanese archipelago. It is built in a mine, 1 km deep, and measures 40 meters high and another 40 meters wide, which gives a volume similar to that of a fifteen floors building. However, the authentic protagonist of this article is the Underground Observatory of Neutrinos of Jiangmen, which is housed in the Chinese province of Guangdong. Like the Super-Kamiokande Japanese, Juno, which is how this Chinese observatory is known for its English denomination (Jiangmen Underground Neutrino Observatory), It is a real monster. His heart is a cylindrical pool 44 meters deep that is housed in an underground chamber with granite walls. The neutrin detector consists of a 41.1 meters in diameter stainless steel mesh that supports an acrylic sphere of 35.4 meters in diameter The neutrin detector consists of a 41.1 meters in diameter stainless steel mesh that supports an acrylic sphere of 35.4 meters in diameter. This container is full of a very exotic liquid expressly designed to interact with neutrinos and produce a light of light that can be detected. Juno contains no less than 20,000 tons of this liquid, which allows him to erect himself as the largest neutrin detector on the planet. The composition of this fluid seeks to maximize the amount of light generated by the interaction of each neutrino. Its three fundamental components are linear alkyl benzene, which acts as a solvent; 2,5-difeniloxazole, which is the molecule that is excited when a neutrino interacts with herwhich causes the emission of a flash of light; And, finally, 1.4-bis (2-methylstiril) benzene, which absorbs the ultraviolet light that emits 2.5-difeniloxazole and re-enters it with a longer wavelength that is easier to detect. The flashes of light are collected by 45,000 photomultiplier tubes that cover the inner surface of the sphere. By measuring the intensity, position and duration of these flashes, scientists can reconstruct the trajectory and energy of each neutrino. And all this for what? Wang Yifang explains it to usJuno spokesman: “This observatory will allow scientists to address fundamental questions about the nature of matter and the universe.” Neither more nor less.

11 functions and tricks to squeeze the new characteristics of chatgpt

by

We are going to give you several tricks and tips for Squeeze GPT-5 to the maximumthe latest version of the model of artificial intelligence that uses Chatgpt To work. With this new version new functions and characteristics have also arrived that we are going to teach you to squeeze. GPT-5 is available for all Chatgpt users, both free and payment, so many of these functions will serve you in both cases. Of course, you know that if you are paying you can use more times some of the key aspects, such as photographic edition. But before starting, remember that the first improvement is always reliability, so Chatgpt now responds more reliably. We are not going to focus on that, but I will remind you that the best is always Do not lower your guard with the answersand always check what he tells you, because some data and information may be incorrect. You no longer have to choose specific model In previous versions, the same GPT had different versions, some to give faster answers and others to better reason these answers. Now, GPT-5 is a unified modelwhich means that you no longer have to spend time on this choice. Now, what happens is that you write to chatgpt what you want, and The AI ​​choose which of its ways to use depending on the difficulty of the task or context. Of course, there is a small trick, and it is that You can give a signal to use a model concrete adding things like “think more like this” to activate the reflexive mode. Come on, you can do it manual. Soser context for your chats Another of the functions of GPT-5, like every new version, is Expand the context and memory. If GPT-4 had up to 8,000 context tokens, GPT-5 has up to 128,000 tokens in its most advanced version, which become almost 96,000 words. Free users have about 8,000 tokens, which are approximately 6,000 words. And how can you take advantage of this in practice? Well, to have longer conversations without chatgpt, forgetting what was said above, or to be able to copy and paste much longer texts as complete items or reports, and that can analyze it. Use multimodal understanding Another characteristics of GPT-5 is The improvement of its multimodal capacity. This means that in addition to text, you can also process images, graphics, diagrams or even video sequences. GPT-4 could already describe images in a limited way, but now you can reason about them in a broader way. With this, you can add images or graphics and ask Chatgpt questions about it and its content, or even a summary. By power, you can Upload the photo of a book page and ask you to read it and tell you key pointsso that I can extract the text from that image and summarize it. You can also help with mathematics and sciences. Chatgpt can handle several images A small tip about its multimodal understanding is that GPT-5 can handle mçultiples images If you contribute them in a sequence. For example, you can send two images and ask that you make a comparison, and the AI ​​will understand the context of both of doing so. In addition to creating them, you can edit images Chatgpt has improved its image creation capacity with GPT-5. On the one hand, this means that creation has been improved of images from scratch from your descriptions. In addition, as at the same time has improved the analysis of images you upload, when you ask to reimagine a photo to create an image from it you will also notice that quality has improved a lot. But in addition to that, a trick is that Chatgpt can now edit your photos In several ways. For example, you can ask you to eliminate elements of a photo such as people or some object that bothers, or add elements such as putting mustache in the photo. Create programs and games and use them in chatgpt One of the best GPT-5 characteristics is that not only has its capabilities improved to generate code in several languages, but also allows you to preview what you have created with the. Come on, you can launch the Catgpt’s own code. Imagine you put yourself Create educational games with artificial intelligenceor even Create Rouleta de la Fortuna and Pasapalabra games. When you describe that you believe a certain game and give it the details, chatgpt with GPT-5 will generate the code, and when it ends You will have a button Execute the code which allows you to play what you have created directly in Chatgpt. Take the fullest the new voice mode Voice conversational experience with Chatgpt has improved with GPT-5, and all users have access to the advanced voice mode. Free users can use it for a few hours a month, and those of payment have an almost unlimited use. The understanding of what you say and the way you respond has also improved. One of the things that allows you to do this is use chatgpt as a language teacher. Come on, you can establish the conversational mode to practice a languagetelling him to make the role of a teacher and have a conversation, correcting the mistakes you make when speaking. You can also use it as a real -time translator, and for much more. Finally, remember that chatgpt is multimodal, and that applies to the voice mode. If you are having a spoken conversation, you can upload an image and ask you questions about it, so that you answer you by voice. Chatgpt now has a mode of study Another novelty of the new GPT-5 is the Chatgpt study mode. It is a modality that you can activate so that, when you ask you a question, Chatgpt does not limit the answer. Instead, It will help you step by step to find the solutionor you will prepare exams and questions. Come on, with this mode the AI ​​organizes the information … Read more
