In his mission to follow the movements of North Korea, South Korea has decided to bet on an advanced steering wheel

In South Korea, the surveillance of heaven It is a constant task that is never terminated. Missile tests and the use of low flight drones The need to strengthen detection systems has highlighted by the north. Radars on land, conditioned by the country’s geography, do not always offer the necessary coverage against threats that seek to go unnoticed. To respond to that challenge, Seoul has decided to bet on a new generation of Early alert planescapable of expanding surveillance and ensuring more stable control of your airspace. It is not just about incorporating technology, but ensuring that the country has sufficient means to anticipate any scenario. The search for a new early alert plane It started in 2020when the Defense Procurement Agency (DAPA) approved the second phase of its AEW & C program. By then, South Korea already had four E-737 Peace Eye acquired from Boeing in 2006 and delivered in 2012, but the experience had made it clear that they were not enough. Parliamentary documents revealed in 2019 indicated Availability problems and technical failuress that prevented maintaining the planned patrol rate. To that limitation was added the pressure of an increasingly complex strategic environment, marked by the expansion of North Korean arsenal. A jump in the air surveillance strategy Seoul has opted for an unusual combination until a few years ago: an executive reactor Bombardier Global 6500 equipped with radar The/W-2085 developed by Elta. This system, with active electronic exploration antennas on the sides and additional sensors in the nose and tailallows to monitor in all directions promising a much greater scope than that of conventional radars. With this model, the country is looking for a more compact platform and with operational costs contained compared to larger solutions. The contest was marked by a struggle between two proposals that started from the same base plane, the 6500 global. L3Harris offered to integrate it with the radar the/W-2085, while the European Saab presented its globaleye solution, equipped with the radar Erieye Extended Range. Dapa’s evaluation concluded that there were no major differences in technical performance, but in other aspects. As the agency explainedthe American proposal received more points in operability, maintenance costs and contribution to the local industry, while the Swedish firm stood out in price and contractual conditions. Conceptual Image of Global 6500 for South Korea According to Dapa, the approved budget amounts to 3.87 billion wones, about 2,820 million dollarsand contemplates the incorporation of four planes until 2032. The goal is to have permanent patrols capable of monitoring the national airspace without interruption and coordinating the response in case of crisis. Deliver planning up to that horizon will progressively integrate aircraft in the operations of the Air Force. An E-737 Peace Eye in the United States The industrial component presumably had a relevant weight in the decision. L3harris has been supplying equipment to the South Korean armed forces, from electro-optical and infrared surveillance systems to safe communications and night vision devices. The company has an authorized service center in the country, which reduces maintenance times and simplifies logistics in case of breakdowns. The 6500 global is expected to reinforce the air defense of the Asian country. These devices will be integrated into the grid national Istarconnecting combat sensors and units to generate a complete image of airspace. Its main mission will be to detect intrusions and coordinate the immediate reaction, but its regular use is also contemplated in periods of calm to maintain training and preparation of crews.

Openai is demonstrating to be able to overcome the goal in virality. His mission was not supposed to be that

Openai has launched Sora, its social application with which it invites users to create short videos generated by AI and then share them on that network. The product has turned out to be an immediate viral success, extremely simple to use and highly addictive. So much that he has totally left the company that theoretically dominated this segment perfectly. What happened. Traditional social networks are being filled with videos generated with Sora 2the new and striking video generation model by IA. The expectation seems even to have exceeded what I already generated I see 3Google’s model, but it is that Openai has not been confirmed to offer this model, but has accompanied it with a mobile application that is actually a new social network. One in which all the content is those videos and images generated with Sora. Vibes goal, ridiculous. The first surprise is not so much that the application has been successful, but has left Meta Vibs in an absolute background. The company led by Mark Zuckerberg announced a few days before of Sora 2 its new social network totally dedicated to the content generated by the only days before OpenAi, but the impact, at least in terms of the “noise” generated on social networks, is minimal. There are those who criticize that Vibes is “half cook” and it’s “obtuse” for the difficulty when using it in front of Openai. What Altman’s company has achieved is to win in this New career for the economy of attention. OpenAI strategic turn. But the really remarkable thing about this launch is that it seems to raise a strategic OpenAI turn. The company led by Sam Altman has been promising that We will have an AGI in a few thousand days. That diffuse promise contrasts with a reality: GPT-5 is a good modelbut does not represent a specially striking leap regarding the state of the current art. And given that slow evolution and progression, the solution seems to be to offer AI toys. They already did it with the Studio Ghibli Style Imagesbut Sora 2 and Sora’s app go further. They are AI toys … dangerous. Ai Slop. This model contributes even more to that future in which the “spleen generated by AI” (AI Slop) becomes the most widespread type of content in social networks and the Internet. But there are also (among others) a potential and gigantic privacy problem with Sora’s “cameos”, which can end up helping the generation of deepfakes to shoot. The future was a meme factory. That viral success of the app Sora makes the line be blurred between creators and content consumers and does more than ever who consume it end up creating it and realiment the phenomenon. And that makes AI a meme factory, and not a technology that helps us solve real problems. It is true that there are sectors that are taking advantage of it in professional fields, but the danger is that the focus of AI ends in entertainment and content that can also end up being toxic. The Killer-App of the AI ​​was to create videos. Chatgpt and AI continue without having a “Killer App” definitive practice: they help (more and more, true) to programmers, summary documents and rewrite emails, but for now the current models seem to fall short in their promise to revolutionize our world. Openai has managed to market technology better than anyone, but not because cancer heals or solves economic inequalities: he has caused anyone to create absurd and irresistible videos. The chatgpt of the video has arrived. The truth is that despite whom despite, this is a unique time in the frantic evolution of AI. If Dall-E and Chatgpt were those inflection points for AI that generated images and text respectively, I see 3 and Sora 2 have shown that the video generated by AI is prepared for the mainstreamfor mass consumption, although its long -term value may be questionable. Of course its use as the center of a new era of entertainment is. In Xataka | Differentiating the AI ​​content on the Internet is increasingly difficult. The solution goes through something similar to fillets

We knew that the Dart mission changed Dimorphos’ trajectory. What we did not know is that its form also changed

At the end of September 2022, the Dart mission (Double Asteroid Redirection Test) It made historyInterestingly, stamping against an asteroid. The milestone was not on the impact itself but on achieving with him slightly divert the trajectory of an asteroid, Dimorphos. The expected and the unexpected. In the almost three years since then, we have been learning New details on the effects of Dart’s impact on Asteroid Dimorphos. Now we know, for example, that Dart not only managed to divert the orbital trajectory of the space rock; He also achieved with his impact to make the asteroid orbit deform significantly What happened. The asteroid, explained the team, initially had an oblate form, that is, flattened in the poles, such as the earth, “the shape of a hamburger.” After the impact, Dimorphos became a rather prolata, elongated in the poles, like a rugby ball. “For the most part, our predictions pre-impact on how Dart would change the way Didymos and her moon (Dimorphos) move in space were correct,” ” explained in a press release Derek Richardson, who led the analysis of the effects of the probe. “But there are some unexpected discoveries that help provide a better image on how asteroids and other small bodies are formed and evolved over time.” Tumbos. According to the team that analyzed these orbital changes, the impact would have made dimorphs pass from a state of equilibrium with its main asteroid Didymos similar to that of our moon with the earth, to an irregular one. That is, dimorphs always gave the same face to Didymos, at least Until Dart arrived. Now the system is out of its alignment, Richardson pointed out. This implies that it can stagger changing orientation, even ending up “tumbos”, rotating chaotically and unpredictable. Asteroid formation. Thanks to studies such as the one conducted by Richardson and the team, we can access new clues about the formation of asteroids. As explained by the team, the impact released small rocks that remained in the orbit of the asteroid system. These contributed to altering the orbital movement in the system, but these changes in the gravitational balance do not seem to have altered the form of didymos. This implies, the team added, that the main asteroid of the system was rigid and firm enough to maintain its form after the formation of its moon dimorphs. The details of the work were Published in an article In the magazine Planetary Science Journal. Hera’s turn. The scientific community now has new eyes on the Didymos system, those of Herathe mission of the European Space Agency (ESA) aimed at monitoring the system and collect new data In situ. If everything continues as planned, Hera will begin in October a trip that will lead her to reach the double asteroid towards the end of 2026. The data compiled by Hera They will allow an even more exhaustive analysis of the impact of the Dart mission. This in turn will be what gives us key clues that allow us to plan missions that protect our planet from the asteroid shock.

one million terabytes and 24,000 nvidia chips for a key mission

In an increasingly digitized world and where artificial intelligence (AI) is transforming the way we work, investigate and relate, the supercomputing has established itself as the rod of measure technological power. It is a strategic resource that allows us to accelerate advances in science, innovation and defense. Not all super -taders play in the same league. Frontierof the United States Department of Energy, marked a milestone in 2022 by becoming the first to officially overcome the exaescala barrier, with 1,102 Exaflops in the Benchmark HPL. To that achievement they joined later The Captain and Auroraalso on American soil, consolidating its leadership position on paper. In the case of China, the information remains opaque, With very few public data about the status of their projects. Europe, however, just moved. Your first superorous to exaescala is already underway: Jupiter. Installed in the Jülich Supercomputing Centerin Germany, one of the most important advanced research poles of the continent. Jupiter is driven by the platform Nvidia Grace Hopper And Evidan xh3000 Bullsequana architecture is based on a liquid -refrigerated system designed to squeeze efficiency and performance. It is expected to reach up to 90 exaflops in artificial intelligence loads. Their applications will be diverse: from climatic research to neuroscience and quantum simulation, placing Europe in a new calculation capacity league. An inauguration with historical air September 5 The official inauguration ceremony in Jülich took placewith the presence of German authorities, European and leaders of the technology industry. German Chancellor Friedrich Merz presented him as a Pioneer project for Europe. “With Jupiter, Germany now has the fastest supercomputer in Europe and the fastest room in the world. Open completely new possibilities, from the training of AI models to scientific simulations.” In the Top500 list, Jupiter already appears as the fourth Most powerful supercomputer in the world, only behind the Captain, Frontier and Aurora in the United States. The European Union stands outIn addition, what works entirely with renewable energyby hiring green supply on the German network, and that its Rack Jedi leads the Green500 energy efficiency classification. The figures behind Jupiter To understand its magnitude, just review some technical data: 24,000 superchips nvidia gh200 grace hopper 51,000 network connections with infiniband quantum-2 technology Storage capacity close to an exabyte Modular installation with 50 specialized containers Maximum consumption of 17 MW, equivalent to about 11,000 homes A rack called Jedi leads the World Energy Efficiency Classification Why is it relevant to Europe Europe had been behind in the supercomputing career for years, with a landscape dominated by the United States. JUPITER offers researchers, companies and academic centers direct access to a top -level machine without depending on external resources. This means forming their own talent, consolidating experience in the management of these systems and reinforcing technological sovereignty at a time when artificial intelligence and calculation capacity have become strategic issues. Concrete applications The first projects already selected show how far a supercomputer of this category can go: Climate: The ECMWF works with a kilometer scale simulations, capable of representing extreme storms and feeding the Destination Earth project, whose objective is to build digital twins of the planet European: The Trustllm consortium trains language models in multiple European languages ​​for industrial and scientific applications Neuroscience: With the arbor simulator, neurons behavior will be modeled at the subcellular level, key to developing therapies against diseases such as Alzheimer’s Quantum: JUPITER aims to exceed the 50 -QBITS record in simulation, a relevant step towards quantum practical computing Astrophysics: The Max Planck Institute will use it to study cosmic reion, the period in which the first stars and galaxies emerged Particle physics: The University of Wuppertal will increase the resolution of its calculations on the Mon, which could open the door to new discoveries Video models: The University of Munich explores compression and dissemination architectures to advance applications that go from medicine to autonomous driving Multimodal models: The University of Lisbon Scale open and multilingual models, integrating different fields of science and automatic learning Access and future Researchers may request access to the system in calls that will be held twice a year. At the moment, there are already 30 projects underway. The expected useful life is at least six years, which guarantees continuity and stability in a land where technological cycles are increasingly fast. A strategic movement Jupiter is not just a technological achievement. It is a strategic commitment to provide Europe on their own capacity in an area where part of the future of artificial science and intelligence is played. With him, the continent finally has a tool that allows him compete at the highest levelwith energy efficiency and technological independence.

His next mission for this year is to divert an asteroid

We may not finally need Bruce Willis, but Armageddon It is no longer a movie as unlikely as it seemed. After the United States managed to divert an asteroid for the first time in history, China prepares to launch its own planetary defense mission this year. Of course, with something that NASA did not have: a second probe to record everything live. A little context. In 2013, NASA and the European Space Agency created the AIDA program to demonstrate the asteroid deviation close to Earth. He NASA Dart Kinetic Impactor It would crash at high speed over a small asteroid called Dimorfo, and the AIM orbiter developed by that would record the event live to measure the effects of impact. ESA ended up abandoning the development of AIM due to the lack of financial support of the Member States. But NASA continued with the development of Dart and, on September 26, 2022, the asteroid successfully diverted, with a small Italian Cubesat (Lyciacube) as the only witness of the feat. The hera mission of ESA, AIM spiritual successor, is traveling to Dimorfo to take data From his arrival in December 2026, four years after the impact. Now it’s China. Although NASA-that collaboration did not materialize as conceived, China has its own version of AIDA. For now it is known as “experimental test of the asteroid defense system close to Earth”, but is very close to becoming a reality (probably with a less aseptic name). Wu Weiren, designer of some of the most important missions of the Chinese space program, commented at a conference in Heféi that the launch is scheduled as this year aboard a CZ-3B rocket. If it succeeds, the mission will make China the second country in the world deliberately against an asteroid to modify its orbit. And what is better: with a second probe loaded with sensors to record the live impact. Two ships instead of one. Unlike NASA’s mission, which sent a single Kamikaze probe with the Italian Cubesat inside, China’s plan contemplates the launch of two ships: an impactor and an observer that will make an exhaustive recognition. As for the asteroid, The chosen one is 2020 pn1located in an orbit of horseshoe to dozens of millions of kilometers from the earth. As details Wu Weirenthe observer will come first to map and obtain precise physical data. Shortly after, the impact ship will collide at high speed against the asteroid under the watchful eye of the observer, in addition to a combined network of telescopes on land and space. The objective is to accurately measure changes in orbit, morphology and material expelled by the clash of the ship, to evaluate the effectiveness of the impact. The goal is even more modest than that of Dart: produce an orbital deviation of between 3 and 5 centimeters. More difficult than it seems. The ship will have to travel for months, adjusting its course to hit an object of just a few hundred meters in diameter, with a minimum margin of error. To which you have to add uncertainty about the composition of the asteroid: it is not the same to collide with a solid rock than against an amalgam of loose rubble. The challenge is immense. “How to hit a fly from tens of millions of kilometers away”, PUBLISH THE GLOBAL Times. But NASA showed that it is possible, and now China has the opportunity to confirm that humanity is able to defend itself from one of the greatest existential threats faced by the Earth: the impact of a nearby object. The first test of a long -term plan. This mission is just the first piece of an ambitious puzzle with which China plans to establish a complete detection and defense system against asteroids. The country already has a land surveillance network, which includes the telescope of the Purple Mountain Observatory and the “China Compound Eye” project, a set of radars capable of obtaining high -precision images of asteroids to millions of kilometers. The plan is to complement this terrestrial network with a fleet of observation satellites in space and have a catalog of options to act as a threat is detected. It is not science fiction, but a real and urgent plan. In early 2025, in the midst of the growing concern for asteroid 2024 YR4, China opened a recruitment process In search of experts in astrophysics and international cooperation to create their own planetary defense force. Space muscle demonstration. This new mission comes at a time when China’s space program advances at a dizzying pace in contrast to NASA’s scientific cuts. China’s experience in handling deep space is growing, and has already achieved milestones that the United States does not possess, such as bringing samples of the hidden face of the moon. In May of this year, China also launched the Tianwen-2 probe, which is directed to the quasi-satellite Kamo’oalewa to collect the first samples of this peculiar object, A probable fragment of our moon. The samples would arrive to the Earth in 2027. Subsequently, the ship will continue its trip to a cometr of the main belt, in the farthest mission ever undertaken by the country. The next step: bring the first samples of Mars with Tianwen-3, something that seems to China will also get Before the United States and Europe.

An Voyager 2 mission review has revealed that Uranus is not as described

Uranus, the planet that orbits side, has always been the weirdo of our solar system. Since NASA’s voyager 2 probe survived him in 1986astronomers have dealt with a disconcerting mystery: unlike their gaseous Jupiter, Saturn and Neptune, Uranus seemed not to have an important internal heat source. It was, in appearance, an inert and energetically dead world. But that idea has just jumped through the air. A little context. In January 1986, the Voyager 2 probe became the first and only ship to visit Uranus, giving us the most iconic images of the planet and the data that laid the foundations of everything we know about him. One of the most important was its energy balance, the heat it emits with respect to the sun. The giant planets have an immense mass, so they retain a considerable amount of the heat of their formation and release it over billions of years. This internal heat flow is evident in Jupiter, Saturn and Neptune. However, the Iris instrument of Voyager 2 told a very different story about Uranus. According to a 1990 study, the planet issued an almost identical amount of energy to what it received from the sun: the internal heat flow was statistically indistinguishable from zero. Uranus thus became the anomaly of the Solar System: an ice cream giant that, for some reason, had cooled much faster or formed in a completely different way from the other planets. I wasn’t dead. Nor of Parranda. A New study led by researchers from the Houston University It has finally resolved the mystery. After analyzing decades of data, scientists have shown that Uranus does emit more heat than he receives from the Sun. It is not the inert planet we thought, but a dynamic world with an internal engine That, although modest, is very present in the energy balance. The error was not in the measurements of Voyager 2, but in the interpretation of a single snapshot over time. This is where the new study led by Xinyue Wang and Liming Li, from the University of Houston. Instead of based only on the overflow of 1986, his team compiled and analyzed data from a much longer period (from 1946 to 2030), covering almost a complete orbit of Uranus, which lasts 84 terrestrial years. Uranus is a planet of extremes. Its rotation axis is inclined 97.7 degrees, so it basically rolls on its orbit. Combined with a remarkably long orbit, it causes extreme stations that last about 21 years each, with a hemisphere bathed by continuous sunlight while the other remains in an icy darkness. The researchers discovered that this seasonal cycle is the key to everything. The solar energy that absorbs the planet is not constant, but varies significantly throughout its year. The 1986 analyzes, made near the winter solstice of the northern hemisphere, did not capture the complete image. By averaging the energy balance throughout the orbit, the results are unequivocal: Uranus consistently emits 12.5% more energy than he receives from the sun. Not so weird bug. Uranus now fits much better in the formation models of giant planets. It has an internal engine, although it is weaker than that of its neighbors, which suggests that its evolution was more similar to that of the rest of what was thought. This finding not only changes our understanding about how giant planets are formed and evolved, but also arrives at the right time, when Both NASA as China prepare missions To visit it. If the question is why Voyager 2 obtained such a misleading image of the planet, the answer is simply bad luck. In the days before the 1986 overfather, the Sun bombed Uranus with An unusually powerful geomagnetic storm. This phenomenon compressed the magnetosphere of the planet, which caused the ship to capture data in a day of extreme conditions.

The exomars mission already accumulates 20 years of calvary and bad luck

Mars seems to have a special online to the European space agency and, more specifically, to the exomars mission and his Rover Rosalind Franklin. What promised to be a pioneer mission for Europe in the search for past life on the red planet has become a true technological and geopolitical calvary, a saga of misfortunes that leads to ask if the rover will not simply be cursed. From NASA to Russia. The exomars odyssey It started two decades agoin 2005, with the aim of launching a rover to Mars in 2011. Initially conceived in collaboration with NASA, the mission suffered a first capital setback in 2012, when the US agency, due to the cost overruns in projects such as the James Webb space telescope, decided to retire. Nor was the European prominence of the mission funny. This first jug of cold water forced ESA to look for a new partner to desperate. The Russian Space Agency Roscosmos. Russia would provide the proton rockets for the two phases of the mission and a crucial element: the Kazachok descent module that would be in charge of the Martian landing of the rover. A second setback. The first phase of the mission, launched in 2016included the Trace Gas Orbiter probe, which operates successfully in the Martian orbit. Also the Schiaparelli landing module, designed to test “mooring” technologies. Schiaparelli crashed into the surface because he misunderstood the accelerometer readings: he mistakenly assumed that he had landed and fired the roof and parachute early. On Earth, the launch of the Rover, scheduled for 2018, was postponed to 2020 for problems with The parachutes and delays in the delivery of components. Then, the Covid-19 pandemia He added more delays, pushing the launch window at 2022. And then, war. The Rover was baptized ‘Rosalind Franklin’ in honor of the British crystallographer whose x -ray diffraction images were fundamental to reveal the double helix structure of the DNA. When everything seemed (finally) on track, with the rover ready for a few months of takeoff, the Russian invasion of Ukraine in February 2022 He dynamited collaboration. ESA, in an inevitable decision, suspended cooperation with Roscosmos, leaving Rosalind Franklin orphan of a pitcher and, above all, of landing platform. A devastating blow. Light at the end of the tunnel. Baptized ‘Rosalind Franklin’ in honor of the British crystallographer whose X -ray diffraction images were fundamental to reveal the double propeller structure of the DNA, the rover did not raise head. But that decided not to throw in the towel. Member States pledged new financing in the mission and ESA chose to develop a European landing platform. Thales Alenia Space was selected as the main contractor in April 2024 with a contract of 522 million euros, but it is Airbus Defense and Space the one that will be in charge of design and construction of the landing module, which, ironically, keep a great resemblance With Russian Kazachok. And now what. When light was finally seen at the end of the tunnel, The budget proposed by the White House For NASA it seems to leave out the contribution of the US agency in the European Rover. According to Eric Berger, from Ars Technica, in addition to the Mars Sample Mission Return of Return of the Red Planet, in which Europe also participated, The contribution of NASA was disappearing in the European Rover Rosalind Franklin. It was a modest, but crucial contribution to the mission: Plutonium -based RHU heater. For now, the launch date of the Misión Exomars and the Rover Rosalind Franklin remains scheduled by the end of 2028, with A landing in the Martian plain Oxia Planum planned for 2030. A long trajectory to avoid the season of global dust storms on Mars. Rover Rosalind Franklin will carry its drill capable of drilling up to two meters under the surface, where possible biofirms would be protected from radiation.

Finding quick and reliable tests for Alzheimer’s is a key mission for science. And we have a new candidate

Ahead of Alzheimer’s. It is a simple but difficult objective to achieve since the symptoms of this disease tend to appear when the disorder is advanced and has already caused important damage to our brain. A difficult objective but what It can help us treat the disease With greater efficacy, managing to delay the appearance of some of its symptoms such as cognitive deterioration. Maybe one day helps us cure it. In the blood. A group of researchers has tested a new blood test aimed at the early detection of Alzheimer’s disease. The test is based on a biomarker present in the blood, P-TAU217, which shows changes long before the appearance of symptoms in people with the disease. The study showed precision when detecting the disease greater than 90%. These results also did not depend on the age or gender of the participants, either on the existence of comorbidities or whether the test was carried out by specialists or primary care personnel. This marker can be measured with simple and cheap tools and the process is automatic, which can facilitate detection in various circumstances, democratizing the diagnosis of the disease. “This is an important step to bring simple blood tests for Alzheimer’s disease to health systems around the world,” said the team responsible for the essay in a press release. P-TAU217. Detection methods based on the P-TAU217 compound They are not exactly new. These types of tools are already implemented in the United States and it is expected that they will soon reach the rest of the world, says the team itself. The new method seeks to offer a simpler alternative to the available tools. The new study analyzed the precision of this New Test in the conditions in which it would be used, not only in specialized clinics but also in primary care. In three countries. The essay was carried out from 1,767 participants with cognitive symptoms distributed in three countries: Spain, Italy and Sweden. The details of the study were published In an article In the magazine Nature Medicine. The New Test included two cut points. One of them served to interpret the negative results: from this threshold the test rules out the presence of the disease. The second of the cut points serves to find the positive ones: this threshold shows the presence of the disease. This leaves, between one cut and another, a “gray zone” in which the results are inconcuing, however the use of a test with a single threshold slightly reduced the accuracy of the diagnostic tool. Above 90%. The study showed that the test achieved an accuracy between 92% and 94% when used in its two cuts mode. However, this precision fell to levels between 83% and 87% when only a cutting point was used and applied to more advanced ages. “When the method was tested in patient sides, the precision was between 92% and 94%,” NOëlle Warmenhoven explainedfirst signer of the study. “This is promising since this method will probably become one of the most used in clinical practice around the world.” In Xataka | We have a new “theory of all” to understand Alzheimer’s.

There are farms that have more than 80,000 captivity scorpions and a strange mission: milking them

Insect farms seem to come to stay. The European Union wants begin to be part of our diet And there are countries like Spain that are putting the batteries. An example is the Tebrio Plant in Salamancawhat will be the Greater Flour worm farm. But, in addition to producing food, we also raise other unusual animals, such as scorpions. In countries like Egypt, Mexico or China, scorpions have become a business. And not only do they raise them: they order them. Life poison. Scorpion is an animal that cool. There are more than 2,000 species, they are all over the world, except in Antarctica, and They have extraordinary characteristics. The sting and tweezers attract attention, but they have a very hard exoskeleton, they can regulate the amount of poison they inject at will, they have an excellent night vision, great control of metabolism and endure their breath almost a week. Come on, they have been here for 400 million years and are older than dinosaurs, so they have had to force everything that has been preceded. Now, much less than we can think are dangerous for humans. The poison is designed for the hunt for their prey and, of those 2,000 species, only between 25 and 50 would be in danger (and the bites of many of them would not be lethal). Farms. And it is precisely that poison that interests us as a species. The amount of poison that a few hundred copies have would be insufficient, so places are needed in which to house thousands of these arachnids. And when I talk about thousands … it’s thousands. Nigeria is one power in the breeding of scorpions, but also China, Thailand, Mexico or Egypt. In this country There are facilities With 80,000 copies. Eighty thousand scorpions, which is said soon. These farms require specific conditions for parenting, with areas adapted to the species in which they have specialized and a number of specimens that varies depending on the objective. Thus, farms can be used to have copies to release and help us control pests. They can be part of a laboratory of Antivenene Research Or, directly, a farm in which we milked them. Milking scorpions. Ordering animals has nothing strange, but we must recognize that ordering scorpions is something that comes out of the ordinary. What interests is his poison, and farmers like Metin Orenler give the key in ABS Science To do so: patience, pulse, courage and a game of tweezers with which to extract the poison. The problem is that each of its scorpions (Androctonus turiyensiswhere appropriate) only produces two milligrams of poison a day. It is very little and is the reason why these farms have tens of thousands of copies. In the case of Orenler, 20,000 scorpions. Liquid gold. After milking it, they freeze it into liquid nitrogen, they make it powder and this Turkish farm sells it to Europe to Medical researchbut there are other countries (especially in Asia) that are also very interested in this scorpion poison dust. And this is where the key is: the scorpion poison is the liquid More expensive of the world. How much? Orender states that ten million liter. It is necessary to milked a lot to reach those amounts, it is evident, but still … Why is it paid so much? Potential. For many reasons, really. We have already talked about the research, and in ABC, Volker Herzig, who is a professor at the University of Sunshine Coast, comments that peptides and proteins, very numerous in the scorpion venom, can be isolated and analyzed to create something beneficial for us. For example, for the biological control of insects and parasites in agriculture or veterinary, but also to treat human diseases. Herzig explains that they are powerful and very specific compounds and that, if they manage to combine properly, they can be almost miraculous. “Let’s say that a protein is hyperactive in a disease, so if you find a poison toxin – scorpion – that manages to block it, a measure can be created to combat it.” The researcher points out that they have found components with potential to treat epilepsy, irritable colon and even strokes. Dorothy Wai is a researcher at the Institute of Pharmaceutical Sciences of Monash and also studies medical uses of the poison. And his research focuses on the treatment of autoimmune diseases, such as multiple sclerosis, thanks to a protein called KV1.3 present in this substance. Following the venom trace. The problem is that Herzig also comments that, although he has received offers from farms to buy poison, he rarely buys because “you can never be sure of the origin.” That is, if he needs something very specific and contact him from India (something that has happened), he does not know if they really want to sell the poison because of how lucrative it is or because it is the concrete venom you need for your research. “I think that several more toxinologists have received similar offers,” he says, adding that what he has decided to make samples is … traveling through Europe and manually milking scorpions raised by individuals. He assures that there is “a great movement in Europe of people who raise spiders and scorpions as pets”, and what really awakens my curiosity, and also a itching in the back, is the phrase of “visits to someone and has 200 copies in the basement.” Cosmetics. Wait, how much money these researchers have? The answer is that it is not they who take the bulk of production, but the cosmetics industry, which adds scorpion or extracts to their products, as well as traditional medicine companies. Teams like Herzig’s no longer collect poison, because when they sequence DNA, they don’t need more, but to create traditional medicines not backed by scientific evidence or new cosmetics, you do need large quantities. On this, the researcher comments that he does not know what they put to these products and that it would be cautious, … Read more

China is getting closer to overcoming NASA in its Martian mission. And just invited other countries to join

Mars Return’s drama. Since I arrived in Mars in 2021, NASA’s Perseverance Rover has been depositing Roca nuclei and Marciano Regolito in hermetic tubes dispersed by the red planet for your future collection. Mars Sample Return is NASA’s mission and the European Space Agency to recover those samples (38 tubes in total) and bring them to Earth. Last year, with a forecast of delays in sample return up to 2039 and an estimated budget of between 7,700 and 11,000 million dollars, NASA de facto canceled Mars Sample Return to control the cost overheads. The agency listened to alternative proposals and, at the beginning of 2025, delayed the decision for a year to Choose between two options: An internal architecture of the NASA JPL laboratory or a commercial ship of the private industry. China has taken the lead. With Mars Sample Return in suspense, China has many ballots to Become the first country to bring Martian soil samples. The launch of the Chinese mission Tianwen-3 is scheduled for 2028after Tianwen-2 launches up to an asteroid near Earth this year as proof of previous technological concept. Tianwen-3 is a simpler mission that Mars Sample Return because it would collect the samples of the landing place, instead of the carefully selected rock nuclei in different places by the Rover Perseverance. However, it has the same objectives as the NASA mission: analyze samples on Earth in search of organic substances and “biosignuras”, signs of past life. Tianwen-3 opens to other countries. The China Space Agency (CNSA) also announced that its sampling recovery mission will be open to international cooperation. Scientists and space agencies around the world can propose until June 30 scientific experiments or instruments to include in the Chinese mission. Tianwen-3 will carry 15 kg of foreign instruments on the ship that will return to the Earth with the samples and 5 kg of additional foreign instruments in the orbiter that will remain in Martian orbit. It could be the case that the European Space Agency, which already participated in Mars Sample Return with the return ship, made a proposal and ended up advancing NASA in this way. Multimillionaires to the rescue. Meanwhile, in the United States, Spacex and Blue Origin have proposed NASA to take advantage of the same ships they have in development for Artemis lunar missions (Starship and Blue Moon) with the aim of recovering Mars samples. However, Elon Musk and Jeff Bezos have already received numerous public contracts, and a third millionaire, Peter Beck, CEO of the Rocket Lab’s rocket company, It has a more concrete and simple proposal. A solution of 4,000 million dollars with simple technology to bring the samples in 2031, the same year as the Chinese nave Tianwen-3 would return to the earth. Rocket Lab architecture. Three launches in total for all ships of the mission. The orbiter Mars Telecommunications Orbiter would facilitate communication between Mars and Earth. The Lander Lander Lander lands would land on the surface of Mars to collect the samples with the same supersonic aerocies and parachutes that the Martian Rovers use. The Mars Ascent Vehicle, designed as a single rocket stage, would take off towards the Martian orbit with chemical propulsion Using Electron Rutherford engines from Rocket Lab. The Earth Return Orbiter ship would collect the samples in the Martian orbit to bring them back to the earth using similar engines. The three goals of the space race. Decide what NASA decides, China is determined to take advantage of the delays of Mars Sample Return to get the symbolic victory of bringing the first samples of Mars, as has already happened with the Chang’e-6 mission and the first samples of the hidden face of the moon. At the same time, there are two other goals in the space race. The United States announced to hype and saucer that would take the first woman to the moon with the Artemis III mission (planned by 2027), but its launch has been delayed and now the architecture of every Artemis program, as well as that of Mars Sampple Return, It is in question for the numerous cost overruns of the SLS rocket and Starship’s delays. China, meanwhile, plans to reach the moon in 2030. Then, both countries will try to take the first humans to Mars. Image | POT In Xataka | NASA had marked two major short -term objectives.
