China increasingly dominates technology on earth. There is a place where they are still far from Occiden

by

A recent report The New York Times He has evidenced the Chinese difficulty to compete with Spacex in the deployment of communications satellites. While Musk’s company already accumulates 8,000 Starlink satellitesthe two main Chinese networks just add 120 units in orbit. Why is it important. Low orbit satellites are strategic for autonomous cars, war with drones and military surveillance. China considers Starlink a direct threat and has planned two megaconstellations with 27,000 satellites between them. Qianfan, the constellation of low orbit satellites developed by China, anticipated having 650 operating satellites at the end of the year. Shanghai Spacesail Technologies, the company after the project, has only managed to put 90 in orbit since August. Guowang, an alternative born in 2020, is even worse: 34 satellites of the 13,000 planned for the next decade. The context. The Popular Chinese Liberation Army See Starlink as something “deeply integrated into the US military combat system”. It is not empty paranoia: this network is essential to coordinate drones in Ukraine and Spacex has government contracts for spying and missile monitoring. The background. China has not solved the key problem that Spacex solved years ago: reusable rockets. Chinese companies continue to wear single -use pitchers, which multiplies costs and reduces the frequency of launches. The Falcon 9 can reuse its first stage up to 20 times, greatly reducing the costs. After five hundred missionsit is still the reference. Chinese candidates –Long March 8R, Zhuque-3, Tianlong-3– accumulate failures and delays. Yes, but. China is negotiating Contracts with 30 countries to access Qianfan. He has already signed agreements in Brazil, Thailand, Malaysia and Kazakhstan, taking advantage of certain misgivings towards American technology dependence. The rhythm of Chinese launches accelerates: more than thirty missions in the first half, putting 150 satellites in orbit. But they need to multiply by five or six the rhythm to fulfill their international radio frequency commitments. In addition, there are some counterparts to your proposal: The decisive moment. Chinese megaconstellations must launch half of their satellites in five years after obtaining the frequencies, completing the deployment in seven. Not fulfilling could force them to reduce the size of the networks. Main loser? China dominates manufacturing, batteries, solar panels and traditional (non -advanced) semiconductors. But in sectors that require maximum risk assumption – Biotechnology, the space – the United States maintains a decisive advantage. Getting smaller in some scenarios, but maintains it. The business mentality that rewards rapid and cheap failures against guaranteed successes makes the difference between Spacex and its Chinese rivals.

Better not wait for the August 12 peak

If the Perseids are the Rain of fleeting stars More popular in the northern hemisphere is for something. They appear in full summer, when the skies are clear, the nights are more pleasant and many are on vacation. But this year they have a problem. Luna almost full at the worst moment. In 2025, the Perseidas Activity Peak The night will take place from August 12 to 13. As every year, it is the moment in which we should see the most meteor. But this time, the Perseids will share the stage with an guest star that nobody wants on an astronomical observation night: a large and brilliant moon. According to the August lunar calendar, the full moon will come on day 9. This means that for the night of 12, our satellite It will be in the diminishing phase gibosa90%illuminated. Although we move away from the cities, the natural light pollution of the moon will complicate the visibility of the weakest meteors. Only the most spectacular and bright cars will stand out in heaven. When to see the Perseids. According to him National Geographic Institutethe moment with the greatest abundance of meteoros will occur on August 12 just after the sunset, around 22:00. The moon will appear on the horizon approximately an hour later, so we will have a very scarce margin to accustom the eyes to the dark and enjoy the hunt for perseiders. Our advice to have a more relaxed and lasting experience: not wait until then. The Perseids or tears of San Lorenzo They are active from July 17 to August 24, so this weekend we can see them burning in the night sky. And the growing moon will be hidden soon through the west, leaving a night with a perfect dark sky for observation. How to locate them in heaven. Whether you decide to get ahead and if you prefer to wait, the first thing is get away from the city’s lights: Go to a beach, the field or the mountain, especially if it is “in the shadow” of the moon. The less light pollutionmore stars and persistent you can see. The most popular meteor rain of the summer owes its name to the constellation of Perseus, but the most effective way to see them is not to look for the constellation on the map, but to stare at the darkest part of the sky (care with the neck, better to be lying) because they can appear anywhere, provided there are no clouds, and the greatest possible field of vision will be good for you. Your eyes need between 15 and 20 minutes to adapt to total darkness, so it is best to avoid using the mobile. Anyway, perseiders are so fast that it is difficult to take pictures. A time-lapse or video are safer options. For the same reason, it is not worth using telescopes or prismatic.

cut mountains

by

The tunnels have saved us from surroundings to mountains and rock surfaces for decades. However, it is not the only technique to shorten time and develop new roads that connect cities with each other. In this aspect, it is worth telling how China once again demonstrates its ability to transform the landscape with a technique that seems taken from a science fiction film: literally cut mountains To build roads. Explosives, giant excavators and a millimeter planning is necessary to divide rock formations of hundreds of meters high. How the technique works. After A geological study Exhaustive to determine the composition of the mountain and plan the cuts so that they do not compromise the stability of the land, engineers use controlled explosives to create the first fractures, followed by specialized heavy machinery that can excavate tens of meters deep per day. The remaining walls are stabilized with metal meshes, projected concrete and drainage systems to avoid landslides. The final result is A clean step through the mountainwith vertical walls up to 200 meters high that seems that someone with a giant knife has crossed them. A technique in multiple regions of China. These ‘cut walls’ can be seen mainly in The mountainous provinces of GuizhouYunnan and Sichuan, where the karst terrain and the complicated rock formations made the construction of traditional tunnels impracticable. Projects as prominent as the Guiyang-Qianxi highway or the Taihang mountain pass have turned hours of hours into minutes. It has also been used in the construction of the High Speed Railroad that connects Beijing with Guangzhou, where several sections go through literally games in half. Click the image to watch the video Why not tunnels are used. The decision to cut instead of drilling usually comes Due to technical criteria and specific economics. In land with high concentration of groundwater or unstable rock formations, building tunnels can be more expensive and risky than direct cut. In addition, the maintenance of an open step is considerably simpler than that of a tunnel, which requires constant ventilation, lighting and drainage systems. In low -rise mountains, the cut also allows the greater proliferation of heavy vehicles, especially in an economy that depends so much on the transport of road goods. Beyond China. Although China has perfected and popularized this technique, it is not the only country that uses it. Norway uses similar methods in its fjords, where the characteristics of the land make the cut more viable than drilling (although in this country we also have spectacular projects of tunnels under construction such as Rogfast). In the United States, Cumberland Gap’s pass in the Apalaches was created by cutting techniques, although on a smaller scale. However, no country matches the ambition and scale of Chinese projects, which have become an art the mountain cut. Environmental impact. Although the benefits of using this technique are evident, especially in the aspect of econic development and its effectiveness to connect remote regions, this technique also generates a certain debate around environmental impact. And it is that this type of constructions can end up destroying local ecosystems, altering natural drainage patterns or fragmenting wildlife habitats, not to mention the amount of dust and noise during its construction that can generate millions of tons in waste. It can also be said that it is not the most used technique, since the tunnels remain the preference except exceptional cases.

Zuckerberg is offering 1,000 million to take the best engineers. The problem is that they are rejecting it

by

After being considered The cover of the AIGoal did not live up to expectations with The flame launch 4. So, in the Search for general artificial intelligence (AGI), Mark Zuckerberg He entered “Founder Mode”. Your great goal? Start winning another of the wars that I was losing: The attraction of talent. The ambition behind their Galactic offers believe A new upper class in Silicon Valley. Waiting to see results from his new Superintelligence team, of China majority, Zuck It has encountered a company where for the moment it has not been able to fish despite offers of up to 1,000 million dollars, According to Wired. It’s about Thinking Machines Labthe startup of Look Murati. So powerful gentleman is not a money. It is not yet known exactly what they are in in Thinking Machines Lab, but among its more than 50 employees there is a lot of talent, starting with Murati, one of the chatgpt mothers and head of OpenAi technology until less than a year ago. Goal has made offers to more than ten startup employees. And what offers. The Zuckerberg company has offered payments of between 50 and 100 million euros in the first year, with amounts ranging from 200 to 500 million dollars in four years, according to Wired. With an exception: an offer of 1,000 million in several years. And neither has a goal to attract talent: for now, employees are not accepting offers. The reason. Sam Altman came to affirm that Meta failed to take away talent because Openai employees believed that his company would be the best positioned for “Develop superintelligence“And” the company that is worth more. “According to Wired sources, which has led to Thinking Machines Lab to retain talent has to do with the leadership style of Alexandr Wangco -founder of Scale aiand that Zuckerberg has put in charge of the galactic team superintelligence labs. Despite their history, they mention their lack of experience (28 years) as one of the causes not to want to work under their command. That has not prevented the round of signings centered on OpenAi and Deepmind to be successful, despite having engineers from the same profile of the Murati team. Mark Chen, Cro, from Openai, told the respect that they felt that “Someone has sneaked into our house and stole something“. According to him Wall Street JournalChen would have been another of the AI geniuses to which Zuckerberg would have offered an offer on 1,000 million. Important, “for the moment”. In a market that does not stop moving, the deadlines are crucial and very changing decisions. Sam Altman He presumed That goal was not able to take any of its best employees despite offers of 100 million a year. However, a few days later, It was confirmed that with his irrigation of finishing money he had attracted: Bi Suchao (ex-openai. China): He was co-creator of the GPT-4o and O4-mini voice mode. Chang Huiwen (Ex-Openai. China): Co-Creator of the GPT-4O image generator. Before he worked in Google, where he created Maskit and Muse. Lin Ji (Ex-Openai. China): He worked on the creation of several language models, from GPT-4O to GPT-4.5. He also dealt with the reasoning of Operator. Ren Hongyu (ex-openai. China): He helped create several models and led the post-training team. Zhao Shengjia (Ex-Openai. China): He directed the synthetic data program and was key in the creation of Chatgpt. Yu Jiahui (ex-openai. China) led the perception team. Trapit Bansal (Ex-Openai. India): co-creator of several language models and pioneer of the combination between reinforced learning and ‘chain of thought’. It seems that Zuck Yes managed to leave several of the best, with a Chinese majority. You have to wait to see if the finishing CEO does not cause any ravage in Thinking Machines Lab. Ilya Sutskeveranother ancient heavyweight of OpenAi, a goal was not successful, even offering him Buy your startup for 32,000 million dollars. But the Meta team did Add to Daniel Grossyour adventure partner. In Apple they are falling. After fishing in Deepmind and Openai, goal pulled wallet with another Big Tech, Apple. Achievement take to Ruoming Pangfor 200 million dollars distributed in several years, an amount superior even to the one Tim Cook takes In a similar period. After this announcement, key for being Pang responsible for Apple’s models, Cupertino’s company lost two of the employees who worked for him: Mark Lee and Tom Gunter. Yesterday Bloomberg reported fourth big exit: Bowen Zhang. A plan that goes beyond talent. With the Metaverso as long -term betand with him Wall Street supportMark Zuckerberg goes with everything for AI. And everything is not just talent. He is so hurry to lead the AI who has done something unusual: Build a tent databasewaiting for it to be built ‘Hyperion‘, its mastodontic Data Center for the size of Manhattan. Feeding these megaconstructions need energy, a lot of energy. And goal too is launched for hereven betting on nuclear centrals that They were going to close soon.

What’s behind the fever for drinking electrolytes every day

by

During a trip to Mexico, the heat passed me an invoice. She was soaked in sweat, exhausted, with dry mouth, despite not stopping drinking water. At that time, a friend offered me a drink with electrolytes. I tried it, without many expectations … but the truth is that something changed. I felt better. It was the first time I tried something like that. Since then, I have asked myself: did you really need those electrolytes or was it pure placebo effect? What are exactly? To understand it easily, electrolytes are minerals such as sodium, potassium, magnesium, calcium or chloride. However, there is a superlative difference that makes it different: they are electrically loaded. In other words, they play a fundamental role in processes such as heart rate regulation, muscles contraction, nerve function and liquid balance in the body, According to Medlineplus. And how do you lose them? They leave with sweat, with urine, and also when you are sick and your body loses liquid quickly. In such cases, replenishing them is not a whim, but a necessity. Dr. Javier Marhuenda, nutrition expert, He has warned at the Spanish Academy of Nutrition and Dietetics in losing too many can have serious consequences: from fatigue and spasms to heart problems or seizures. Should we replenish them daily? The short answer is: not necessarily. And for most people, it is not recommended either. In a report for The New York Times They have pointed out That there is a belief that we need to replace electrolytes constantly, even in moderate training or in everyday life. However, this theory does not have as much scientific support as it seems. “Everyone believes that they need to replenish lost electrolytes immediately,” Dr. Tamara Hew-Boutler, a scientist of sports medicine at Wayne State University, said for the New York environment. It is easier to find them. Actually, a balanced diet already provides the necessary electrolytes. According to nutritionist Heidi Skolnik cited in the same mediumit is not necessary to resort to supplements to obtain electrolytes: everyday foods such as bananas, nuts, legumes or dairy products already provide minerals. Only in specific cases: a dehydration caused by severe diarrhea, high fever, very prolonged exercise sessions or intense exposure to heat, makes sense to use specific drinks with electrolytes. In these scenarios, isotonic drinks can be useful because they usually contain more sodium and potassium than conventional sports options. Optimized water. Social networks have turned “improved” water into a welfare ritual. Electrolyte mixtures, superfoods, adaptogens, natural caffeine and vitamins parade each morning in Stanley vessels and Owala bottles. In an article for glamor They have summarized it In a very ironic way: “The water alone is out of fashion.” Danika Daal, Content creator that shares hydration routines in ASMR, He has commented In the fashion magazine: “The videos about electrolytes have had excellent performance. It is a recent trend and there is still little information available.” In this way, electrolytes have thus added to a broader wave of supplements turned into lifestyle: Collagen milkshakes, Tinuras, vitamin envelopes and “loaded waters” that combine multiple ingredients to achieve functional and tasty well -being. According to Stacie Stephenson, an expert in functional medicine interviewed by glamor: “If the taste helps a person drink more water, welcome. But there is nothing wrong with classical water.” But is there any risk? The electrolyte content in these products is not usually so high as to cause hypernatremia (too sodium) or hyperkalemia (too potassium), although it is important to check tags: some drinks contain Both sugar and a soda. In addition, like most supplements, They are not regulated with the same rigor as medications. Another risk is to drink too much water without replenishing sodium. This imbalance, known as hyponatremiA, it is uncommon but it can be serious, especially in athletes that train for many hours. So, I need them or not? The answer is not black or white. As Marhuenda has summarized: “A person must use these drinks based on their individual needs and their level of activity.” A yoga class is not the same in the park as a triathlon in summer. For those who do intense exercise, they work in the sun or are sick, electrolytes can be useful, even necessary. But for the general population, with a balanced diet and an active lifestyle but not extreme, water – yes, only water – remains enough. Between fashion and physiology. That day in that town in Mexico, the bottle of electrolytes was my relief. Did you really need those minerals or was it the power of salty flavor and autosugestion? Maybe both. The truth is that, beyond marketing, science insists that hydration begins with water. As Dr. Kenefick has detailed to The New York Times: “Many drinks are marketed using electrolytes as a marketing tool.” And while the market bombards us with promises of optimized hydration, the most effective recommendation remains that your mother repeated again and again: drink water.

The arcade boom in Madrid and other Spanish cities

by

The recreational have come back to stay. The neuralgic center of meeting so many young people from the eighties and the nineties seem to ride the wave of nostalgia, and they are more than a curiosity, or temporary exhibitions to rediscover the classic games. Throughout Spain, and especially in Madrid, they are emerging from arcade theme bars to associations that make their background available to visitors, and that guarantee a nostalgic zambombazo … and discovery. Madrid, Mecca del Arcade. Although they begin to abound throughout Spain, without a doubt the main core of recovery of recreational is in Madrid. The relocation in Vallecas of The Arcade temple (which is also an association in the southern Madrid area dedicated to the dissemination, preservation and restoration of Arcades and Pinballs) has caused this type of premises to speak again, which in most cases are arms of associations of friends of the retroinformatics (for example, NEXTAGEconsecrated to the recovery of dance machines). It also happens in Retro Factory From Alcorcón and Parla, which, like the Arcade Temple, includes in its facilities a video game memorabilia museum. But there are more variants in the capital: in Zoo arcade They are also dedicated to the repair and conservation of old machines, in a business parallel to the premises that allow players to test the recreational. And finally it is Next Levelthe most accessible of all these projects: bars with machines of all kinds that already have two very central stores in Madrid and have just opened an additional one in Barcelona. Retro Spain. Although they abound in Madrid, of course they are not the only places where retro recreational machines can be accessed. Some examples, apart from the new Next Level store: Arcade Planet and Check Point Arcade Bar In Seville, Arcade Levels in Zaragoza or Pixelandgames In Logroño. To all of them are added video game museums that usually include machines to try, such as the Muvi of Cangas, the Vintage Arcade Museum from IBI (Alicante) and the recent Video game museum from Madrid. Do you have change? As for the way of accessing the games, all these proposals work very similarly: in no machine you have to take coins, but the games are open to infinite credits. In some of these stores you have to pay a rate for spending all day (as in the specialized in Japanese machines Arcade Rebirth) or for a limited time (usually one hour, in most cases). And on the other hand there are bars like Next Level, where a consumption is required to play. Disseminating spirit The interesting thing about some of these proposals is the disseminating spirit that leads to riding something that works economically, but also disseminates the culture of arcade. Manuel Vargas, from The Arcade Museum, tells us that “I had been thinking about making an association with several colleagues”, and apart from the aforementioned exhibition, between their walls they have “105 arcades and several old consoles that can also be played. The space is about 600 meters, and we have a conference room for magazine presentations, books and games.” On the other hand, Curro Quevedo, from Zoo Arcade, tells us that they also related to that spirit, made “a chronology of the arcade world from the former like ‘Space Invaders’ to the last dance or augmented reality machines.” He also tells us that in his 42 machines “we have sought that each machine is unique and has different types of hardware and different controls to be able to see their evolution a bit.” Referring to the competition that has emerged in recent times between similar premises, he affirms that, related to that spirit of wanting to spread historical games, “nobody thinks of competitors, since they are not very profitable businesses, it is more about being able to share a passion” How does nostalgia work? By cycles: We return again and again to claim fashions, successes and trends from past decades (or decades as a whole, in fact), and then tired, declare them “burned” and let some time pass before The next generation decides to rescue that point from the past again. The eighties, after the absolute saturation we have lived with products such as ‘Stranger Things’, now go through that Phase of tiredalthough recreational rooms, for what is seen, seem to have dodged that trend. They are more active than ever. Fever for recreational. The recreational machine rooms were in the eighties A unique meeting point for the youngest: Not only the video games that were in them had a visual quality and a spectacularity far superior to the eight -bit consolers and microorder in the houses. They were also sites where relationships were developed and generated their own fauna that then did not translate with any subsequent environment: hence the powerful nostalgia effect they arouse. Games can be recovered through emulation (or even with Own Machines at home), But the atmosphere is not. That is why they sprout as mushrooms, a multitude of bars and recreational premises (removing the neighborhood danger plus that the rooms had a few decades ago, of course).

put their cities to compete with each other

by

The United States dominates artificial intelligence, but China already steps on your heels and do not release the accelerator. China bets on a Focus centered on the AI Open Source and Much more efficient models From the economic point of view. But the only AI race is not with the United States, within China there is fierce competition among several cities to rise as the center of the AI. Subsidies. China is supporting AI companies with a carrier. As reported in SCMPthe Shanghai government has launched an ambitious subsidy program of 1,000 million yuan (about 120 million euros) for the artificial intelligence industry. The package is aimed at reducing costs for startups that offer AI solutions and also facilitate their adoption by local businesses. 60% of the money will be used for computing capacity, 30% will go to discounts of third -party AI models and 10% to acquire data to train the models. The other AI race. We always talk about the competition between the United States and China to lead the AI, but there is also a lot of rivalry within China itself. With this plan, Shanghai seeks to be more competitive in front of other cities that are also neuralgic centers for AI such as Hangzhou, Shenzhen or Beijing. Shanghai. It is one of the most important cities in China, but the cost of life is higher and expenses such as the rental of the offices are too high. This makes many startups choose other cheaper cities like Hangzhou. This plan seeks to attract new talent and that more companies Shenzhen. It is the technological city par excellence in China. In it they have their headquarters like Huawei, DJI and Tencent. In addition, there are many robotics companies and like Ubtech either Intellifusion. In Shenzhen they also have ambitious plans to compete in that internal race, such as this subsidy of 545 million euros which was announced months ago oriented to the AI industry. Hangzhou Shenzhen was the center of innovation, but for a while in Hangzhou they are stealing the position. Located only two hours from Shanghai, it has strengthened as the favorite destination for AI and Robotics companies. It is the home of the “six small dragons”, six startups that are leading the sector and among which are Deepseek and UNITREE. It also has its Government program To enhance AI companies and attract talent. Beijing. And the capital could not be missing. Here is the headquarters of some of the most important Chinese companies such as Baidu, Xiaomi, Bytedance (Tiktok), Meituan or JD.com. As for its role in the AI race, more than a Startup hub, Beijing rises as the core of the investigation. Here are The headquarters of the Beijing Academy of Artificial Intelligence and the Beijing Institute for Artificial Intelligencetwo organisms with strong government support. Compete inside to lead out. The internal race does not divert China from its global objective, in fact, it is part of its strategy to lead outside its borders. According to Guo WandaVice President of the Chinese Development Institute: ”China needs a set of nerve centers to overcome the United States, given its enormous size and talent reserve. China thus bets on a coordinated state strategy where everyone competes with each other, but at the same time compete together against the United States.

The solution to the drone problem was in an invention of 500 years

by

Although for a while to this part The drones It seems that they are associated To the war machinery of the different Conflicts on the planetthe truth is that its utility has always been ambicious much further of the contests. These devices could be the solution to many of the problems of the big cities, but they have several “buts”, and one in particular. It turns out that the solution has been able to be in a notebook for centuries. Leonardo and a “modern” dilemma. The genius Leonardo da Vincialthough limited by the technology of his time, he seems to have once again found validity five centuries later. Their notebooks, full of visionary schemes, included the Famous “Air Screw”a helical design conceived as a flying machine that, although it was never built or viable with the media of the Renaissance, already represented an early idea of propeller generating support. Now, a study from Johns Hopkins University, Available in Arxiv And still pending pairs, it points to this mechanism could solve one of the most serious problems of current drones: excessive noise. A contemporary problem. The drones, no doubt, have become a omnipresent tool: They serve For bailouts in The Himalayasfor Environmental experiments in Pacific Islands, to Military Missionsartistic or even recreational. However, society is beginning to perceive them as a growing source of noise pollution. A 2021 report I already noticed that the noise of the drones not only equals, but it is More annoying than traffic or conventional aviation. The reason is not only the sound intensity, but the quality of the frequencies that generate: acute, sinusoidal and persistent tones, which bounce on the ground and amplify its irritating effect. Parallel investigations They have explored metamorphic materials capable of absorbing until 94% of the noisebut the great challenge is still to rethink the propeller itself. Renaissance inspiration. This is where the researchers led By Suryansh Prakhar They look at Leonardo. That Air screwpossibly inspired by the beginning of Archimedes’ screwwas three -dimensional modeling by CAD and subjected to numerical simulations to evaluate their performance against conventional two -blade rotors. Although in its Original Conception It had to be driven by men running around an axis (which made it unfeasible in its time), its helical geometry was surprisingly promising. The modernized model, based on the design ELICO from the University of Maryland in 2020, he showed that the air screw was not only able to generate support, but did With acoustic advantages and energy efficiency. Science verdict. The results They indicated that, for the same lifting load, the air screw requires Less mechanical power and produce Less noise than a conventional propeller. Its largest contact with air allows you to turn more slowly, thus reducing turbulence and emitting smaller, less irritating and rapid dissipation sounds. In practical terms, the Leonardo design It would not exceed modern propellers in absolute thrust capacity or performance optimization, but it does offer a concrete way to solve the problem of noise in densely populated urban environments, where the social acceptance of drones is still limited. LESSONS OF THE PAST. He study It does not propose to immediately replace current rotors, but to point out that unconventional geometries, inspired by ideas such as Da Vinci, can open roads to drones most silent and sustainable. The paradox is eloquent: centuries of aerospace research had not seriously considered this helical form, and now science recognizes that a fifteenth century sketch It contains useful clues for 21st century engineering. In Prakhar’s wordsthe objective is to continue exploring traditional, experimental and biomimetic configurations to perfect aerodynamics and aeracoustics of drones. Ultimately, rather than demonstrating that Leonardo “invented modern drone”, the investigation Validate your talent to think radically differently, remembering on the path that technological progress does not always advance in a straight line and that sometimes the future needs the past to find answers.

When the US began to investigate a nuclear waste tank he found an even worse nightmare: radioactive wasps

by

If you are even the noses of the velutinasthe Backpacks and the Tigres mosquitoes and Japanesethink about this: there are people in South Carolina (USA) that what fears right now is the stalking of radioactive wasps. It sounds crazy, but it makes all the meaning of the world if one takes into account that there, near a plant in which in its day pieces for nuclear bombs were manufactured, They just found A loop with a radiation level ten times above what is allowed. The big question is … how is it possible? What happened? That a few days ago the US Department of Energy published A report which has generated Polvareda in the country’s media. And rightly. The document does not go demand and supply, renewable or prices, but of something much more picturesque: earlier than the month, on Thursday 3 to be precise, some operators located near Aikenin South Carolina, a wasps nest with a radiation level ten times higher to what federal regulations allow. The authorities insist In any case where there is no risk. Where did they find it? Near a radioactive waste tank Savannah River Sitea nuclear material processing center located in South Carolina, next to the Savannah River, and that rose to mid -last century to refine useful materials for weapons creation. The NBC chain states that in its day, at the beginning of the cold war, it was used to manufacture the plutonium nuclei necessary to mount nuclear pumps. Now the installation is dedicated to other works, such as fuel production for nuclear centrals and cleaning tasks, but some sources They point that has generated More than 625 million Of liters of nuclear waste, an amount more than considerable that, once processed, it stayed at around 129 million. 43 underground tanks remain in use. OTHER EIGHT ARE CLOSED. What did they do with the nest? They sprayed him with insecticide, they removed him and discarded him as a radioactive residue. Finally the team prepared A reporta document that took more than expected because its authors dedicated themselves to review Previous cases of fauna pollution to be sure of your criteria. The document concludes that “more actions on the land” are necessary. Is anything else known? Yes. To begin with that they only found the loop, No wasps. Aiken Standard Clarify In any case that if insects had been located, they would probably present quite lower pollution levels. The same newspaper indicates that, after detecting the nest, the radiological control operating staff (RCO) inspected the surroundings without identifying more pollution or threats to the workers. The area in which the nest appeared is inside the plant, where underground steel tanks and several meters deep are preserved. The CNN chain collect Savannah River Mission Completion statements that rule out that there is a risk that the wasps created by the loop can fly outside their facilities. The reason: the normal thing is that they do not move too far from their nests. How is it possible? That is the million dollar question. The report speaks of “inherited radioactive pollution” and “not related to a loss of control”. The event would therefore be explained by the residual radioactivity That remained when the center was fully operational, not for possible leaks. The text in any case does not seem to have satisfied the Savannah River Site Watch surveillance team, which considers that it is incomplete because it does not detail where pollution came from or how exactly came to insects. “I am furious because SRS did not explain where radioactive waste comes from or if there is any type of escape in the tanks that the public must know,” Recognize Tom Clementsgroup manager. One of the keys would be the type of nest, since not all wasps use the same materials to create their homes.

This CEO is delighted to fire employees and replace them with AI

by

The AI comes For our jobswe listen to it constantly and there are already a few companies that have opted for replace your human employees with IAS. Judging by their statements to Gizmodoit is what Elijah Clark likes to do the most, CEO of a company that is dedicated to advising high positions to precisely automate its companies implementing AI. Without tapujos. In 2024 the CEO of Duolingo was proud to announce that They were going to fire 10% of their translators to put an AI And then he said feeling surprised by the amount of criticisms received. Clark takes it further and does not cut when talking about saying goodbye to replace them with an AI. In fact, he is delighted with the idea. “As CEO, I can say that I am very excited with this. I have fired employees for AI,” he says. Elijah Clark fired 27 of the 30 employees in sales team that directed and presumes that “now they get in less than an hour what they did in a week.” Who is this man. Navigating Your LinkedIn We see that it is dedicated to advising other companies in process automation. “Focus on your passion, automates the rest,” is the slogan that stands out in Your website. We can also read messages that say that “human errors cost companies up to 30% of their annual income” or “do not waste 20 hours a week in tasks that a machine can complete in minutes.” Thus, this aggressive rhetoric and his love for saying goodbye to people in the AI are understood a little better: he lives on it and it seems that it is doing well. “The CEOs hire me to find out how to use AI to cut jobs. Not in ten years. Right now.” Rage Bait. He ‘Rage Baiting‘(Ira bait) is a technique that is used a lot in social networks and consists of generating a strong, anger or anger emotional reaction, to generate many interactions.

Salesforce’s case It is a good example. The company announced that it was going to hire 2,000 new employees to boost their AI products. The AI still needs accompaniment. The integration of agents in companies is being quite chaotic, so much that there are already demand for experts to fix the pifias that are leaving the AI. Some companies that rushed to replace their employees with AI They have started backing Oa pause your plans. Although the agents AI They are already a realitythey are demonstrating that They are not so capable as we thought and They make many mistakesat least for now.
