endure the weight of 96 trucks at the same time

by

China is the ideal place for the most adventurous engineers. To the country’s taste for huge constructions (as turbines), an extremely complex orography is added that leads engineers to devise extreme solutions to connect the territories. Thus arise infarction tunnels, impossible roadshe longest maritime bridge in the world either gigantic dams. One of its regions, Guizhou, is one that needs a very specific infrastructure to not be isolated, and that is where the New higher bridge in the world. And the fire test before its inauguration has consisted of filling it with trucks. The bridge. A few years ago we talked about Lege bridge over the Beipan River as the highest in the world. It was at that time when 565 meters above the waters. But another bridge was needed on the same river, and the decision was made to build it in the Huajiang cannon. The challenge was capital, due to characteristics that the new bridge should have: Two towers of 265 and 205 meters at the ends. Cables of 9,000 tons each. A total length of 2,890 meters. The vain has a length of 1,420 meters. And what interests us: the road is 625 meters from the ground, reaching the end of the towers at 776 meters. Record time. To visualize the height, Two Eiffel Tower would enterone on the other, under the hanging section, but also supposes the longest hanging segment of the world built in a mountainous area. The works They started In 2021 and in January of this year it was reported that 75% of the project had been completed. The rhythm in recent months has been agile and we are at a point where the main works have been completed. In total, it is estimated that 439,000 m³ of concrete and 49,000 tons of steel have been used these four years. Fire test. And the most curious thing is how those responsible for the work have decided Test infrastructure before the opening scheduled by the end of September. They have used 96 trucks, as if it were a parade, which have been placed online throughout the hanging section for five days. In total, 3,000 tons that add to the rest of the tests that have been carried out in the structure, since many of these constructions in China are executed in areas prone to earthquakes, and the area where the bridge of the Gran Canyon of Huajiang is located is no stranger to earth trembling. In Guizhou, 329 earthquakes have been registered, at least, magnitude four during the last ten years, and that is why the bridge is equipped with sensors that monitor vibrations and structural variables in real time. It is not a whim. In the end, the loading test of that hundred trucks is a more news around the new largest bridge in the world, which is an achievement not only for its height, but for the extreme topographic challenge they have faced. HE esteem that has cost about 280 million dollars and, once open, will cross the canyon In just a couple of minutes when before it took more than an hour. Everything for connect rural areasthis being one of the government’s objectives to improve communications between all regions of the country and that is not only being carried out on land: also in the rivers. The end? Improve all communications to consolidate the ‘New Silk Route‘. Image | CCTV In Xataka | China is moving whole buildings at the same time to build underneath. Because? Because it can

Domotizing with sensors seemed good idea. After several days of testing, Ana has discovered what almost no one tells

by

What can go wrong when you try to domote the kitchen and bathroom … even little by little? Well, many things, as you will discover In this new installment of ‘Domotize or die in the attempt’. Ana has proposed to move forward with her connected house, but what seemed a more or less simple installation of sensors It ends up becoming a succession of failed tests, network errors, double -sided tape and various frustrations. In this episode, the goal is clear: protect the water leak house and automate bath lighting, but the process will not be precisely fluid. Nor short. Not simple. Before entering flour, the first logistic obstacle had to be overcome: shipping. One of the packages with the essential sensors had been lost, which kept the entire process in pause. “It seemed that today’s video was not going to arrive, but finally the package appeared,” says Ana, resigned but relieved. With everything already at home, the installation starts: water sensors at key points such as sink or dishwasher, and a first attempt to leave the presence detection system ready in the bathroom ready. What follows, of course, is not a manual installation. Tape, tests and patience: Home automation is taking pace The first sensors to settle were those of water leaks, and the kitchen was the test field. Ana located the three most critical points: sink, dishwasher and washing machine. He prepared to make tests in real conditions. The result was a constant strip and loosen between theory and practice. “It has taken a little more than I expected”, Says after seeing how the sensor does not react instantly to contact with water. From there, homemade adjustments begin. Place the device as centered as possible, trust that it does not move with the passage of the aspirating robot and wait for the time, the time comes, it really works. Everything pointed out that the Valve Controller would be the perfect brooch: a system that, when detecting a leak, would automatically close the passage key. It made sense, it was well thought out and seemed to fit the logic of the rest of the sensors. But when trying to install it, the thing was twisted. Ana discovers that, despite having the pipes in sight, there is not enough space to place the device. “My joy in a well,” summarizes, with a mixture of rage and resignation. The concept was ideal, the impossible execution. It will touch it back. After the reverse with the valve controller, Ana focuses on the other great objective of the episode: install a LED strip behind the bathroom mirror and accompany it with a presence sensor that activates the light automatically at night. It sounds simple, but only in theory. You have to look for the exact placemake sure that you do not activate with cats, find free plugs, and deal with an app that does not want to collaborate. “Ok, great. It’s a bit slow, but it works,” he says when, finally, he gets everything to react … although not quite as he expected. From there, it is time to test, move the sensor, adjust settings and fight with home automation. Will you get it ready? That is another story. After so much effort, Ana manages to launch her night lighting routine in the bathroom. The sensor detects the movement and lights the LED strip … although not always with the desired speed or precision. Sometimes it takes, sometimes it is activated for no reason. “It works, I would tell you that between 85 and 90 % well,” he acknowledges. It is not perfect, but functional enough to keep it installed. Will it end by polishing the failures? Is it enough when they return from the trip? In the video we see how everything has evolved. With part of the system already underway, Ana begins to think about what is coming: a trip, plants, cats … and the terrace, which stays as a pending task for the next chapter. In the next episode we will see how the house prepares for be outwith automatic irrigation system. At the moment, there is something that is still unresolved: the happy water key controller. “I thank you infinite to leave me a comment to see if I can solve it,” he says, leaving the door open to someone having the answer she has not found. And yes, if you want to see how all this ends, The full video awaits you on the Xataka YouTube channel.

We needed more than ever a way of predicting better storms and hurricanes. AI has solved the problem

by

Among the areas in which Google Deepmind works, Meteorological prediction It is one of the most precision is obtaining thanks to the refinement of artificial intelligence tools designed for it. And the company has just demonstrated that AI can overcome traditional methods in hurricane prediction. And is that your model Weather Lab managed to forecast more accurately The trajectory and intensity of Hurricane Erinwhich went from tropical storm to Category 5 in less than 24 hours A few days ago. The first real exam. Until now, the meteorological models were a promise. Hurricane Erin became the first real -time fire test for the Google system. During the first three critical prediction, the artificial intelligence model exceeded the official forecast so much of the National Center for American Hurricanes such as several traditional physical models, including the most reliable Europeans and American. How it works. Traditional models are based on complex physical equations that recreate current atmospheric conditions: humidity, pressure, temperature. Google’s approach It is radically different. Its AI has been trained with a massive data set that includes historical weather information of the entire land and a specialized database with details of almost 5,000 cyclones observed during the last 45 years. “They match these long historical data with details about how hurricanes behave and statistically combine them to see patterns that the human eye could not detect,” Explain James Franklin, former head of the Hurricane Specialists Unit of the National Hurricane Center. Why does it matter so much. The precise prediction of hurricanes is vital to know what type of measures are needed to protect themselves from them in case of emergencies. The three to five forecast days are crucial to make decisions about evacuations and preparation measures. In Google’s internal tests With storms of 2023 and 2024, its model managed to predict the final location of the cyclones with about 140 kilometers more precision than the European model (ECMWF), considered the most exact available. Exceptional performance. Franklin stands out The performance of the Google system: “It really surpassed the other guides in terms of intensity. It captured the general form of the change of the life cycle almost exactly. practically without error.” The model not only succeeded in the trajectory, but predicted with surprising precision how Erin’s intensity would evolve throughout his life cycle. Still in development. Despite success, the Google model is not ready for public use. Weather Lab includes a warning that recommends trusting the official forecasts of the National Hurricane Center. However, Franklin It is optimistic About the future: “For next year, you will receive a very serious look and will really play a role in the forecasts that leave the Hurricane Center.” Cover image | Brian McGowan In Xataka | It is no longer necessary to pay to transform our photos into what we want.

Imgur’s unfortunate fall

by

Imgur’s story starts in 2009 with a very legitimate purpose: to provide the Internet for a space to house images, when websites of that type did not abound. Your innovative vision became a standardand the service grew like essential livelihood of countless online communities. The corruption and reorientation processes of the classic websites of the Internet, however, have ended up affecting it, and now their users are on a war footing. What was needed. In 2009, Alan Schaaf, a student at the University of Ohio, tired of how difficult it was to upload and host images on the Internet, which generated countless problems of usability and disappearance of files. Created imgur as a simple solution for Hosting of images and in its first five months he came to add a million pages seen. For more than a decade, Imgur was the de facto standard to share images, especially in Reddit and other forumswhere you have tired of seeing the call to Imgur when an image disappeared or did not carry. Sustained growth. Imgur prospered as a company: in 2013 I already had ten employees, and in 2014 They had got 40 million dollars of an investment firm and lived from advertising and payment accounts, which included unlimited space of upload and storage. Free users could create albums and edit their multi-way images, in addition to sharing them, thus becoming a great success proto-instagram. The purchase. Imgur faced his first noticeable crisis when in 2016 Reddit began to host the images locally. It was the beginning of the end: they had ceased to be a standard of storage, and when other websites followed Reddit’s example, in 2021 the company was forced to sell, being acquired by mediabwhich caused the company’s exit from the company. Medialab AI also has the genius and worldstarhiphop song lyrics repository, an impact news website, both heirs, such as Imgur, of more innocent and simple times on the Internet. IMGUR shit. What follows is a shitting process (translation of the concept of ESHITTIFICATION from Cory Doctorow of which We have already spoken on other occasions) Book. The shit It is a pattern in which products and online services decline in quality over time due to the influence of large TECH companies and social networks, which follow benefits search processes that deteriorate the structure of the websites and the relationship with shareholders and customers. Following the guidelines of this process, Medialab AI has made a series of decisions that have been denounced by users and employees: Mass dismissals without prior notice Replacement of human moderators: Users believe that moderation is being replaced by unreliable AI systems. Technical deterioration: systematic failures in basic functions such as notifications, rise in images, and others. Users react. The community has responded to this phenomenon with a Block reaction which has caught attention for the use of images (that is, the unity of expression in Imgur) as a form of complaint. Many users have posted a meme by John Oliver raising their middle finger and saying “Fuck you, Business Daddy”. There is also a movement asking for the boycott, asking users not to enter the web on September 1. Currently, the main page overflows in black images with derogatory messages towards Mediabs. They are regular reactions to Degradation of classic Internet sites that we have been seeing for a few years. With Imgur not only an essential piece of that original Internet, but the symbol of a time in which the foundations of social networks were settling, when they were still an honest point of contact between users and not a mere succession of ads, sponsorships and collection of private data.

5.7% unemployment among the best formed

by

Some of the main gurus technological In Silicon Valleylike Mark Zuckerberg or Mark Chenhead of Development of Chatgpt, have ensured that university titles They are no longer a guarantee To get a good job in your companies. However, thedata of Eurostat and The last Active Population Survey (EPA) are stubborn and insist on demonstrating that people with higher studies suffer rates from Unemployment lower than the rest. Which invites you to deduce that having a university degree or an equivalent higher degree increases the possibilities of Find a jobeven if you are Overcueled for Work That is going to be done. The value of the university degree. The educational level clearly determines the Probability of finding work. Beyond the decrease in the unemployment rate in Spain that has registered the last report, being at 10.29%, the EPA data They reveal that the unemployment of people with higher studies have a 5.7%unemployment rate, while those who have not finished primary education are around 24.5%. Those who have finished ESO lower their unemployment rate to 11.5%. According The published by The worldthese data also show that unemployment has descended much faster among university graduates during the last decade, currently being at 2007 levels, when unemployment among the best formed workers stood at 5.3%. Europe lives a similar situation. This improvement in the unemployment rate of workers with higher education has not been enough to match the European average that, according to The data Eurostat is 4% during the first quarter of 2025, and remains in third place in countries with the highest unemployment rate in this segment of its active population, only surpassed by Turkey and Greece. It is not something strange considering that the general unemployment rate also occupies that place and Spain is not among the countries with the highest number of Employees with higher studies. According to the published data by Euronewsthe countries with the lowest unemployment figures in the segment of the best formed people are Poland and the Czech Republic, with 1.4%. The young people formed still have problems. Although the situation is especially advantageous for those who have already finished the university, it does not happen the same In all age groups. The highest unemployment rate of this active population segment is among the youngest between 20 and 24 years with 16.3%. This data is an indicative of The difficulties to those who face young people who just end their studies. The figures improve as the age strip is increased and employees acquire professional experience. For graduates between 25 and 29 years, the unemployment rate is set at 9.1%. For those over 30 years of age, it is already below 5%. Soft skills: essential complement. Although statistical data They deny technological gurusthe truth is that, if these higher studies are complemented by the so -called soft skills, the possibilities of finding a job in less time They increase. According to data collected in the Hays Guide of the labor market 2025 elaborate By the consulting firm Hays, 63% of Spanish companies prioritize soft skills, especially In technological sectors. Maintain an open attitude to change, teamwork capacity and know communicate effectively In the professional environment they are considered decisive factors for insertion and labor promotion.

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

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.
