A shield as a prelude to an army of Shaheds

That Shahed’s drones of Iranian origin have become a bomb of systematic terror In Ukraine it is out of any doubt. However, on the weekend Russia carried out the largest air attack of the war that is fought in Eastern Europe, and did so with a swarm of Shaheds and a novelty: the drones were accompanied by an enemy improved against kyiv. Your name: Lancet. A night of fire. In what has already been described as the Greater air attack From the beginning of the large -scale invasion in 2022, Russia launched 537 air weapons against Ukraine in a single night, marking a dramatic intensification of its military campaign and advising a hard blow to the already diminished hopes of a negotiated solution. The bombardment included 477 Explosive drones and of distraction, as well as 60 missiles of diverse type, of which 211 drones and 38 missiles were intercepted by the Ukrainian defenses. The magnitude of the attack seems to show a deliberate strategy of Moscow for Erosion systematically The Ukraine Air Defense Network, wearing its western arsenal and causing a logistic collapse in its response capacity. In Lviv, near the border with Poland, several critical facilities were impacted, while in kyiv, Jersón and Járkov they registered dead and residential damage. An F-16 falls. With an increasing Your combat planes As part of its defensive shield, a limited and risky resource. In fact, the F-16 pilot Maksym Ustymenko died After demolishing seven aerial objectives, diverting its aircraft from populated areas before crashing. The Trump administration refusal to sell More patriot systems He has forced Kyiv to reiterate his willingness to acquire them on his own. Zelenskyy, when claiming more western help, He stressed that “Moscow will not stop as long as it has the capacity to launch mass attacks” and demanded greater international pressure on the Kremlin. According to official figuresin just one week, Russia has launched more than 1,270 drones, 114 missiles and about 1,100 planning bombs, in an unpublished aerial offensive that seeks not only to exhaust resources, but also break the moral of the population. Drones and evolution. We have coming counting These weeks. Ukrainian defense minister, Rustem Umerov, explained that Moscow has intensified the combined use of missiles and drones, most of them of the Shahed typeIranian design, which now fly higher, faster and with a greater explosive load, escaping within reach of Ukrainian anti -aircraft mobile units. This qualitative leap in the ability of drones has forced a constant intellectual struggle to Adapt the defenses and find effective solutions. Ukraine has been working for years in electronic and neutralization tactics, but the Technological evolution Russia forces an increasingly sophisticated response. Adaptation cycle. He Shahed-136also known as Geran-2 when used by Moscow, it has gone from being a simple low-cost Iranian drone to become A key piece in the technological war of Ukraine. Its low price, long -range and considerable explosive load have made it especially useful for both attacks and For tactical operations. Despite its intensive use, Ukraine had initially achieved a high index of neutralizationusing a combination of electronic interference, MI-24 helicoptersfighters MIG-29 and machine guns mounted on vehicles to intercept these drones. However, in recent months, a significant evolution in design and tactics has allowed a Increasing number of Shaheds overcome Ukrainian defenses. That, and something More, they have led to Greater air attack to date. The Iranian redesign. The Ukrainian reports They point to several significant improvements in the most recent Shahed. The most obvious: the armor of the motor compartment, which now resists the machine gun shots, while fuel deposits have been relocated from the wings to the central fuselage, reducing vulnerability to lateral impacts. Thus, the most disruptive innovation is the Incorporation of submunitions. These new versions are not only limited to impact, but they can disperse small loads Explosive during the flight, increasing its effectiveness against formations of troops or fortified positions. These artifacts can be released anywhere on the journey, expanding their operational flexibility. In fact, Ukrainian troops in the regions of Sumy and Járkov They have reported The most disconcerting encounters with these drones: no impact is heard, and twenty minutes later an unexpected explosion ensues. Lancet prototype Lancet In addition, and equally important, Shahed Russian waves are now not alone. Together with physical improvements, Russia has changed its way of deploying them. One of the new tactics consists in launching the drones in pairs: one at low altitude, the other at a higher height. The lower drone acts as a decoy, attracting Ukrainian radars, while the superior It goes unnoticed Until the first is destroyed, gaining time and increasing its chances of achieving the goal. The other novel tactic has been the combination of Shaheds with the so -called Lancet drones. We talk about devices smallervery difficult to detect and lethal. Lancet are used to Attack specifically To the Ukrainian teams of antidrón defense, clearing the way for the Shaheds to arrive without opposition. In other words, the evolution of the Lancet has made them a kind of shield before the offensive of Shahed’s swarms. A strategy, the “attack on interceptors”, which has seriously complicated the effectiveness of Ukrainian land mobile defenses. Russian advance on land. Simultaneously to massive air attack, Russian forces advance on the eastern front to the fastest rhythm Since November, supported by high -precision and non -interferible drones guided by optical fiber. Ukrainian commander, Oleksandr Syrsky, He warned On attempts to break the defensive lines in three directions, particularly around the key cities of Kostyantynykka and Pokrovsk, which could be fenced if the offensive rhythm continues. In the north, the Russian troops advance from the Kursk region to Sumy’s, threatening to place themselves soon artillery of its regional capital. Ukrainian government sources They have anticipated that Russia’s terrestrial and aerial offensive will intensify throughout the summer. Doctrinal change and antipersone mines.

What is and how to use Alibaba’s artificial intelligence without having to pay quotas

Let’s explain What is and how to use qwenthe artificial intelligence model created by Alibaba. It is a large language model that comes to compete against Deepseek in Asia, and also passing against other giants in the sector such as Chatgpt, COPILOT either Gemini. We are going to start this article explaining what exactly Qwen is and what are the peculiarities of this model. Then we will pass to Explain how you can start using itsomething quite simple. What is Qwen Qwen is a generative model of artificial intelligence. Specifically it is a Great linguistic model or Large Language Model (LLM), of the same type as Chatgpt and the rest of the alternatives. This AI model has been trained to understand natural language. This is A multimodal AIwhich means that it is able to process and generate both texts and images, code and other elements. Come on, although its main function is to respond by text, you will also be able to ask you to draw and do other tasks. Qwen is too An open source modelthat you can download from specialized pages such as Hugging Face and Modescope, or use in those programs to install models of Artificial Intelligence on your PC. You can use it for free For personal use or research, although its commercial use is limited with restrictions for large companies. This is an important point. Open source models expose their operation, and allow you to use all your functions free Without having to pay quotas. Not all Qwen models are like that, but if you enter its website you can use it for free without problems, and you don’t even need to create an account. Qwen’s first launch was in the beta phase in April 2023, with the name of Tongyi Qianwenwith an internal architecture based on the Meta de Meta ai model. It was publicly launched in September of that same year after receiving the approval of the Chinese government, and in December its first open source models were created. In mid -2024, QWen 2 arrived, also with several open source models, and since then it has been making periodic releases with new innovations, such as QWEN 2.5 in January 2025, and Qwen 3 at the end of April 2025. In this last launch, they claim to have overcome Depseek’s performance. How to use Qwen The easiest way to use Qwen is entering its official websitewhose address is chat.qwen.ai. Here, you will have the option of log in, create an account or continue delightedwhich means that you can use it without having to register anywhere. Of course, if you decide to use it withdrawn, every little you will jump the window to log in, something that can be annoying, but you can keep telling you that you use it if you count. There are some functions that cannot be used without registering, for example, You can’t create videos as a guestyou need to be using an account. On the main screen of Qwen you have a painting to write the text with what you want to ask artificial intelligence. Below are your specific functionsto make concrete requests such as generation and video, images, generate code, summaries, writing aids and more. In the same text box you have A button to activate online searchas well as to use deep thinking modes. On the left there is a + button to attach files and work from them, and the right you can use your voice to make requests. Above left on the web you can choose different models, although by default the most advanced will appear. All you have to do is write to Qwen the question you wantor choose one of its functions and ask you specific questions or requests. Then, the AI ​​will begin to generate the answers immediately. Its operation is the same as that of other models and other artificial intelligence websites. As we have told you, you can also activate a specific function as the creation of drawing. Then, in the prompt that you write to him you do not need or ask him to do that, since he will recognize the function. You ask for what you want and the AI ​​will generate it at the moment.

If we want to know what the end of cash will be like, we just have to look at a country that is living it: China

If you go to China and enter a trade, the most normal thing is that you cannot pay with cash. The blue and green logos of Alipay (Ant Group) and Wechat Pay (Tencent) dominate everything, and have been relegating to traditional coins and bills to an absolute background. While in the West we discuss what to do With cash And Europe considers What will happen to the digital euroIn China they are clear. Cash, nothing. Supermarkets, coffees, taxis, or public transport are some of the many types of scenarios in which The Chinese already pay with Alipay or Wechat Pay. At any point where it is necessary to pay the blue and green logos of these applications, everything dominate, and in fact many businesses do not even have a cash register. According to Le Mondemany taxis and local businesses refuse to accept cash payments, and if they accept them, they do not even have change for buyers. Source: Wikimedia Only the elderly pay with tickets. Ma Dian, a Hubei fruits and vegetable seller, commented in this newspaper how the disappearance of cash payments has lived. “I only accept effective to help the elderly. Below the 80s, practically everyone has made the change. Above, it is much more difficult to adapt.” The elderly are here the greats harmed, and they must ask their relatives for help from the difficulty that they propose to make mobile payments with Alipay or Wechat Pay. QR codes everywhere. The QR codes that we usually see in restaurants in Spain to consult the letter dominate everything in China. There the shops have static or dynamic codes (on screens such as TPV) that customers scan. If we are facing a static code, the client usually has to introduce the amount to be paid. In dynamic codes, the amount is automatically shown. The last step is to authenticate with a password, facial recognition or a fingerprint. Although initially Alipay and Wechat Pay used different codes, in some cases unified QR codes are already used for both apps and it is the client who chooses with which app works on his mobile. Banks lose relevance. The absolute presence of these two digital payment systems have caused Chinese banks – government supplies – also have a secondary role for many clients. It is necessary to have a bank account to have it linked to these applications, but its mobile applications and services are totally overshadowed by Alipay and Wechat Pay, with which users do it practically everything in the field of payments and economic transactions. As John Engen said In American Bankerbanks are often reduced to “passive actors.” Powerful, but at bay. Although both Alibaba and Tencent have managed to monopolize these transactions, the Chinese government It has already demonstrated that remain entities that can be punished in a wrecking way. It happened in 2020 when Ant Group He was about From going to heel. Jack Ma criticized his government at that time, which caused The cancellation of that IPO and An exile of years for one of the great figures of entrepreneurship in China. China wants its digital renminbi. The Chinese Central Bank has been looking for a digital currency for years. Your digital renminbi or Yuan Digital You are also getting more than being an alternative to the dollar: is creating a parallel system. The objective is to have an alternative to the popularity of cryptocurrencies, but a controlled by the Chinese authorities. Although the deployment of this digital currency has been in progress for years, its prominence is very limited, and Momne both Alipay and Wechat Pay continue to dominate everything. And tourists, what. Both platforms, which before They made it difficult To tourists, they have progressively adapted to their needs. For approximately two years both Alipay and Wechat Pay allow foreign visitors to create an account in these applications and associate it with a credit card. Last year too They increased The transaction limits, which in Alipay went from $ 1,000 to 5,000, for example. Better with Chinese mobile number. In Wechat Pay it is even possible to access a kind of purse that they can fill in so as not to associate your Credit card to the app, and thus make small payments. It is necessary to have Internet access for these payments, and hire a SIM or a local ESIM to get a Chinese number – for example, for Validations with SMS – is especially recommended to facilitate this type of transactions.

“If you want to leave at 5 you are not at the right work”

The debate on the balance between working and personal life has gained strength in recent years, especially Among the new generations They are looking for one greater flexibility and well -being. However, new Figures by Silicon Valley as Lucy Guo, millionaire and co -founder of Scale AIThey discard that balance hugging a much more demanding work culture, inspired by the Chinese labor model known as “996” (From nine in the morning to nine at night, six days a week). He is not the only founder who is doing it. Guo, who recently It was recognized by Forbes As the youngest millionaire made to herself, she has made her Extreme workday An example to follow for other startup founders. His lifestyle is generating an intense debate about what professional success really means in the technological era. The founder’s passion for work The co -founder of Scale AI, and CEO of Passes Since 2022, he does not believe in the balance between working and personal life. Tal and counted In an interview for Fortune“I probably don’t have a good balance between my working and personal life. For me, work is not really work. I love doing my job.” This perspective has led her to defend the working hours of up to 90 hours a week as The new standard for those who aspire to succeed in the world of startups. Guo argues that, if a person is looking forward to five in the afternoon to go home, “you may not have the right work.” According to his experience, true motivation arises when work feels like A natural extension of lifenot as an obligation to escape when the day is fulfilled. According to what he told FortuneGuo The day begins At 5:30 in the morning with an intense exercise session. By nine in the morning he is already in the office, and lunch on his desk, without leaving the office. His workday ends towards midnight, when he finally closes his laptop and goes to sleep. Even working 90 hours a week, he says he finds “one or two hours” to be with family and friends: “You always have to find time for that, regardless of how busy you are.” One of the reasons that Lucy Guo keeps in that “always available” state is his obsession to offer the best customer service in his startup. She herself gives her team only five minutes to respond to customers before doing so: “Offering exceptional customer service is what distinguishes the startups from large technological ones. Even if you have fewer customers, it is very possible that the executive director responds to everything, which increases the fidelity of the people. Today, it is impossible for an executive director like Uber’s. That is my mentality,” Guo explained. Although it may seem an extreme approach, Guo is not alone in this way of working. More and more Ceos de Silicon Valley are hugging models that They demand their employees Days of more than 80 hours per week, convinced that passion and total dedication are the Key to success in the technological sector current. The “996” takes over Silicon Valley The traditional work culture of China or Japan, which linked work with values ​​such as honor, respect or loyalty ended up deriving in a culture in which employees They fell collapsed in their workplaces after supporting long days. Days they obeyed to the “996” model in which the long days do not leave time to rest, live, socialize or form a family. There is only work. This philosophy, to which He is getting veto In the main countries that promoted it for its social impact and demographicis now openly defended by founders and CEOS de Silicon Valley, who consider that It is the only way to highlight In an increasingly competitive global market. The drift of Silicon Valley towards this model eternal days is not new. In 2018, Michael Moritz, president of the Capital Fund Sequoia Capital, did An allegation in it Financial Times On how Chinese technology companies carried the concept of hard work at an unthinkable level for Silicon Valley. “Here, the senior managers get to work around 8 in the morning and, often, do not leave until 10 at night. Most do it six days a week,” Moritz praised. Reference companies As a goal either Microsoft They are hardening the Performance assessments of your employees to Encourage them to work harder. The opposite path that Companies have started of those countries that They already know the effects to apply such extreme days. Europe threw up to the wave The “996” wave is also expanding to Europe, where some technological founders rise as apostles of this new labor current, arguing that Europe is sentenced to a secondary role if more hours are worked on. Some countries already They have bought that speech. The Swedish Joel Hellerk, CEO of the Sana Labs artificial intelligence company, He said to his employees that “60 hours per week is the ideal point”, making the message that Serguéi Brin He had imposed In Google. Harry Stebbings, founder of one of the main risk capital investment funds, I also advocated for the “996” day model. “7 days a week is the necessary speed to win right now. There is no margin for the slip. Do not compete against any German company, etc., but against the best in the world,” Stebbings wrote in Your LinkedIn profile. In similar terms, Martin Mignot, a partner of Index Ventures, expressed a risk capital fund based in Switzerland. “Forget about 9 to 5, 996 is the new standard for startups”, wrote in LinkedIn. Nevertheless, There are also discrepant voices With this turn of Silicon Valley and Europe for hardening the working days. Suranga Chandratillake, principal partner of the British investor Balderton Capital, pointed out that this approach was counterproductive for the growth of startups. “All versions of this publication that I have read are of risky capital investors who have never created a technological company. I remember well … Read more

Taiwan believes having found the mythical planet 9 of the Solar System. Instead of looking for his light, he has been looking for his heat

The countless frustrated attempts to find planet 9, a hypothetical giant gas in the confines of our solar system, have aroused the ingenuity of some Taiwanese scientists. Short. For years, astronomers have swept the sky in search of the weak reflection of sunlight that should get to us from planet 9, a demonstratedly ineffective task. Now, a team of researchers has changed the rules of the game with an ingenious idea: instead of looking for it, they have tried to detect their heat. Well, they have found two very promising candidates. Context. Beyond the orbit of Neptune, in an icy and dark region known as the Kuiper belt, the orbits of several objects seem to be grouped in a way that challenges chance. The trajectories of these transneptunian objects (TNos) align as if an invisible hand were guiding them. The most accepted hypothesis to explain this behavior is the existence of an unknown massive planet, the planet 9. Of existing, this distant world would have a mass of between five and ten times that of the earth. The problem is that it would be more than 400 astronomical units, so its light would be incredibly dim. To put it in perspective, Neptune is “only” 30 UA or 4,496 million kilometers. If we can’t see it, maybe we can feel its heat. A team from the National University Tsing Hua in Taiwan believes to have the strongest track in years on the real existence of the most wanted object in our neighborhood. The results of their study are not final, but they reach two promising candidates. Every object with a temperature above absolute zero emits thermal radiation, that is, heat. But while the light decreases with the distance following a relationship of the inverse of the fourth power (1/d4), the heat only decreases with the square of the distance (1/d2). This abysmal difference is the argument used by researchers to focus their search on the heat signature of planet 9. A needle in a haystack. The team resorted to the data of the Akari Space Telescope of Japan. Throwed in 2006, Akari dedicated his useful life to sweeping the full sky in distant infrared light, the perfect range to detect the thermal brightness of the planet 9. And he did it from space, without the interference of the Earth’s atmosphere. Astronomers set out from a list of unprocessed Disssdl detections: more than 5.2 million signals with many false positives. After limiting the search zone, eliminating known objects, filtering sources contaminated by galactic dust clouds and excluding static objects, which seem to be at the same point in observations separated by months, the list was reduced to 393 candidates. Of 393 candidates for two. He touched his hands dirty. The investigators visually inspected the images of the 393 candidates. They ruled out weak detections, artifacts at the edges of the sensor and, above all, the impacts of cosmic rays that can be perceived as a specific source of heat. After this thorough process, there were only two candidates. Two heat points that appeared where planet 9 was expected, had the predicted brightness for the theory and showed the expected movement: they were detected in the same place in a period of 24 hours, but there was no trace of them in the same place six months later. All to demonstrate. The two candidates were baptized as FISSDL J0250422-15011 and FISSDL J0301112-164240. But to verify if these two heat points are really a single object moving in an orbit compatible with planet 9 will need new observations in visible light, with sufficiently powerful telescopes to detect its weak optical brightness and measure its movement with precision. If confirmed, the discovery would not only solve one of the greatest mysteries of modern astronomy, but would revolutionize our understanding about how our own system was formed and evolved. Everything is to be demonstrated, but at least we have a hot trail to continue hunting. Image | ESA, Hubble, M. Kornmesser, CC By 4.0

Ferrari has won on land, but now points to the ocean. His new challenge is a ship that works without a drop of fuel

Ferrari has already conquered the circuits. Now he wants to do the same in the ocean. Its new project has no wheels, nor ailerons, nor a V12 engine. Is called Hypersail And it is a Monohull of regattasalthough that description barely scratches the surface. The Italian brand has decided to build an extreme boat, designed to challenge resistance and engineering. The challenge is not less: to create a 100 -foot monoccasco that literally rises on water, driven only by renewable energies. Without a drop of fuel. A brand that is no longer limited to asphalt For decades, Ferrari has been synonymous with competition, engineering and prestige. Its history has been written in the most demanding paths and in the most select garages in the world. But times are changing. The brand continues to manufacture sports cars, yes, but it is also expanding its playing field. Today Ferrari not only innovates in his vehicles, he also does it in his strategy. Part of that evolution It has to do with the public. The Z and millennial generation They already suppose 40 % of their new buyers. They are younger customers, interested in design and technology, but also in impact and sustainability. And Ferrari is adapting. In that context, Hypersail It does not seem to be a whim or a marketing maneuver. It can be a way to apply everything learned in the asphalt to a different environment, although later also carrying that experience obtained in the water to their cars. Ferrari describes Hypersail Like a floating laboratory. And it is not an exaggeration. The boat, designed by the Naval Architect Guillaume Verdier and directed by the navigator Giovanni SoldiniIt has little to do with a conventional ship. Its structure is designed to keep the helmet out of the water by means of three support points: a foil coupled to a tilting keel, another in the rudder and one side that acts alternately. This provision Reduces friction to a minimum and literally allows “flying” on the waves. The most radical aspect of the project is not seen with the naked eye: it does not carry a combustion engine. All the energy necessary for its operation – from the control of hydraulic systems to navigation computers – is generated on board while sailing. The source is exclusively renewable: solar, wind and kinetic. It is not just about installing panels or captors, but of redesigning each system to be as efficient as possible. There are no hidden generators or plans B. According to the company itself, for many, this combination of total autonomy and oceanic navigation It seemed unfeasible. Ferrari wants to demonstrate that it is perfectly possible. Ferrari not only contributes his name, he actively participates in development. The equipment has applied to the sailboat many of the tools already used in its cars: aerodynamic simulation, advanced structural calculations and a flight control system adapted to the marine environment. That joint work has already resulted in nine patents, with another six in preparation. The ship reacts in real time to sea conditions, adjusting its position as a racing car would make it trace a curve. According to Ferrari, the development of Hypersail is also contributing to the evolution of its sports. The company has not specified specific models, but this technological approach would fit with its current hyper -sports linelike him Ferrari F80a hybrid of 1,200 hp called to continue what Enzo and Laferrari left. Hypersail It is not a finished product. It is an idea under construction. His assembly has already begun in Italy and the launch is scheduled for 2026. For now, Ferrari has shared very few images of the project, and everything indicates that we will have to wait to see more details of its development. Until then, the sailboat will continue to evolve as an open innovation platform. Images | Ferrari In Xataka | In Australia they already have the ‘infinite train’.

China wanted to be the queen of high -speed trains. So he built all the longest bridges in the world

Although Arab Emirates and Saudi Arabia are immersed in a war for have the highest skyscrapers in the worldwhen we talk about megaconstructions, there is no one to have China. It doesn’t matter if we talk about tunnels, Dams, roads and even half -skyscraper. And, when we talk about bridges, there yes There is no rival. From time to time They complete a new pharaonic bridgebut if there is something that shows China’s muscle about it, they are the bridges of the Beijing-Shanghái line. Because it is in it where the three longest bridges are located in the world. Massive and … boring? He Great Danyang-Kunshan bridge It is the longest bridge in the world. It measures just over 164 kilometers and can also be the most boring bridge in the world. The reason is that it is a bridge in which functionality prevailed. It is part of the high -speed network that joins Beijing and Shanghai and in its construction, 10,000 workers used 450,000 tons of steel and 2.3 million m3 of concrete to give life to a structure that had to endure possible ships of ships and the impact of earthquakes. It has 2,000 pillars, 22 tunnels, it has an average altitude of just over 30 meters and trains circulate at a speed of more than 320 km/h. Declaration of intentions. The most striking thing is that it only took four years to complete the work. It is an achievement if we consider that other bridges, such as the Constitution of Cádizthey took more than seven years for about three kilometers. They began in 2006 and the works were completed in 2010, inaugurating both the bridge and the line in 2011. The investment? 8,500 million dollars, and although in later bridges we have seen an aesthetic intention by the engineers, that of Danyang-Kunshan was a declaration of intentions. It became a global reference in rail engineering, but above all in a sample of the Technological advance of the country when undertaking the Infrastructure construction large scale in record time. It is something that has also attracted attention to subsequent works, the speed at which things do, especially, in many occasions of works of great complexity. In dark red, the bridge. In clear red, part of the full line Beijing-Shanghai, a monster. Because although this bridge Have the Guiness record in length and it was an important technical advance, the most imposing thing is that it is only a piece of the puzzle that supposes the high -speed line Between Beijing and Shanghai. It is a connection with a length of 1,318 kilometers and, apart from that of Danyang-Kunshan, there are three other bridges that are on the list of the 10 longest in the world. He Great Bridge of Cangde measures 115.9 kilometers and the Great Tianjin Bridge It “stays” at 113.7 kilometers. The three are the longest in the world, and in the seventh place on the list is the Great Bridge of Beijingwith 48.2 kilometers. The four were completed for the inauguration of the line in 2011, assuming a pharaonic work and, in total, representing a third of the total line length. The artificial island of the Hong-Kong-Zhuhai-Macao bridge, which is a bridge over the water until it becomes a submarine “bridge” It is called obsession. Because, if we look at the list of the longest trains in the world, China is a constant, monopolizing with eight structures the top ten positions. Not only are they very long bridges to house train lines (the Weinan Weije It has 102.7 kilometers, but it is not from the Beijing-Shanghai line), also for roads. The fifth longest bridge in the world is Hong-Kong-Zhuhai-Macaohe longest maritime bridge With 55 kilometers (and, this yes, quite attractive), the eighth of the list is the Quingdao Haiwanwith another 44.5 kilometers of road and the tenth is the bridge of line 1 of the Wuhan Metro with 37.7 kilometers. Within those positions of honor, we only find a 54 -kilometer Thai bridge, the Band Na Expresswayand the Lake Pontchartrain Road in the United States with 38.4 kilometers.

We are sending cannabis samples to space. They will be key to knowing if we can colonize the moon or Mars

Throughout our short space race we have sent the most diverse things to space: from golf balls up to 2,000 small jellyfish (that returned being 60,000), going through latea piece of the Wright brothers, an electric car, a gorilla costume and a pizza. Today to this peculiar list we have to add about 150 cannabis seeds. The reasons? Strictly scientific. Mayasat-1. That is the name they receive both the mission (Integrated within Mission Possible 2025) as the incubator on board which have traveled seeds, algae and human DNA, among other things. In total, 980 samples of 11 different customers. The incubator has been developed by the Genoplant Research Institute in Slovenia, but who has decided to send cannabis seeds to space has been Martian Grow. Transport-14 | Image: Genoplant Mayasat-1 | Image: Genoplant Three laps. Before addressing the why of cannabis, it is convenient to understand what the mission has consisted, whose duration has been three hours. Mayasat-1 took off on Monday 23 at 23:50 aboard a Falcon 9 from Spacex from Vandenberg Space Force Base in California. It reached a height of 520 kilometers (120 kilometers more than the International Space Station) and completed three laps around our planet. Specifically, through polar areas. Because? Because at the North and South poles exposure to radiation is very, much higher than that of Ecuador due to the magnetic field. The objectives. There are several, but they can be summarized as follows: Observe the survival of samples to radiation, microgravity and temperatures of space to have an idea of ​​its ability to resist extreme conditions. Investigate possible adaptations, such as genetic or structural changes, which may have occurred in response to the environmental stress factors. Study the possible implications for the cultivation of plants in space or advances in medicine. Serve as proof of concept for the realization of biological experiments in space. And now yes, cannabis. Božidar Radišič leads the initiative Martian Grow and works as a consultant at the Research Nature Institute in Slovenia. In statements collected by WiredRadišič believes that “sooner or later, we will have lunar bases and cannabis, with its versatility, it is the ideal plant to supply those projects.” In his own words, cannabis “can be a source of food, proteins, construction materials, textiles, hemp, plastic and medicines. I don’t think many other plants give us all these things.” But cannabis … Yes, it is associated with a very different recreational use, but its potential as a plant is tremendous. The Cannabis sativa l produces THC (tetrahydrocannabinol, the main psychoactive compound) and CBD (Cannabidiol, has no psychoactive effects), but these are only two of the More than 550 chemical compounds found to date. And although we do not know what effects each and every one of them has, we do know that the plant is surprisingly resistant. Image | Crystalweed Cannabis Hold on what you throw. Cannabis sativa is a plant that resists ultraviolet rays and gamma radiation (in fact, it is used in its industrial production to decontaminate it). It is also extremely versatile, being able to grow both in Mexico and India, Nepal, Netherlands or Afghanistan despite the fact that its origin is in the Himalayas. Nor is it a plant that needs too much water and can be grown in different types of soils. Their ballots to be a successful space crop are, therefore, abundant on paper. And why send seeds to space? We know that radiation and genetic mutation is able to generate new varieties of species with different properties. “So far more than 3,400 new varieties of more than 210 species of plants using genetic variation induced by radiation and improvement by mutations, “they explain from the International Atomic Energy Agency. For Radišič, that is precisely the key: “It’s about finding out if cosmic conditions affect cannabis genetics, and how they do it, and we may only discover it after several generations.” Radiation exposure can cause mutations, not all negative, not all positive. The key is to detect those that can play in favor of humanity. The problem, of course, is that we need more information. Image | Genoplant Further. We have already cultivated lettuce at the International Space Station, Thalian Arabidopsis on lunar soil and Sent seeds to spacebut all radiation exposure has been in low orbit (up to 2,000 kilometers high). The responses to the radiation of a plant at the International Space Station may not be the same as those of a plant on the moon (at 38,400 kilometers away) or on Mars (54.6 million kilometers). One of the projects that seek to explore how plants cultivated on the moon respond is Leafa NASA mission that will travel to our satellite in the mission Artemis III In 2027. Next steps. When the capsule returns, the Božidar Radišič team and the Faculty of Health Sciences of the University of Ljubljana will study the seeds, their possible mutations and adaptations to obtain results and see which compounds have altered and how. “Whether there are changes as if not, both results will be important for the future, so that we know how to grow cannabis in the space environment,” says Radišič to Wired. An important job. Colonizing the moon or Mars is not only a technological challenge, but also logistics. It is not viable to transport food to keep the population of another planet, so it is capital to learn to cultivate in lunar and Martian soils, completely inhospitable and hostile. There have been advances and research with different proposals For many yearsbut there is still no solution that seems perfect.

In 1950 two scientists wondered if possible a nuclear bomb of 10 gigatons. Its results are hidden locked up

On October 30, 1961, a Soviet bomber furrowed the skies of the Arctic towards Novaya Zemlya. Under his fuselage he hung an artifact the size of a bus: an unprecedented nuclear pump. At 11:32, the called TSAR pump He released. A parachute slowed its fall, allowing the plane to move away. Then, a detonation illuminated the sky with a fireball of almost 10 kilometers in diameter and a fungus -shaped cloud that amounted to more than 65 kilometers. The show was surreal: the pump, With 50 megatones explosive (more than 3,300 times that of Hiroshima), became a symbol of the Nuclear madness. But it could be much worse. The awakening of a new era. With the atomic bombardment of Hiroshima and Nagasaki In August 1945, the world changed irreversibly. Those bombs, 16 and 21 kilotons respectively, they marked the beginning of the destructive power without a paragon of Nuclear weapons. However, despite their fearsome capacity, these weapons were only the first step towards a much more sinister technological escalation. What would later transcend the most reckless imagination. The most powerful pump ever detonated would be That Soviet tsar of 50 megatones, although designed to reach 100. However, the most disturbing thing is that this was not the summit. In hidden, the United States had still planned More huge. The “Super” concept. Hiroshima and Nagasaki bombs were based In fission: A chain reaction in which heavy nuclei are divided releasing energy. But as we said, in parallel to their development, some scientists imagined a second stage: The fusion. This implied union of light nuclei (as deuterium and tritium) to form a heavier one, releasing even more energy. It happens that this reaction required an initial fission explosion to activate, which would give rise to the concept of the Hydrogen pumps. In the 1940s they were just a theoretical speculation … but everything changed very soon. Photograph of a replica of the tarum pump housing Communism comes. After the detonation of the First atomic bomb Soviet in 1949, the United States accelerated its thermonuclear programs. The fear of communism, enhanced by the revolution in China that same year, made the National Security Council recommend quadruply military spending. In that context, the figures of Edward Teller and Stanislaw Ulam appear, who devised The design that even today supports the H bombs. In 1952, the “Mike” test of Operation IVY demonstrated for the first time the Thermonuclear principle: an explosion of 10.4 megatones (500 times Nagasaki) that left a crater of 1,900 meters wide. Despite such force, that was not enough for Teller. The Soundy germ. Two years later, in 1954, the so -called “Shrimp” bomb during the Castle Bravo test. A powerful explosion was expected, but the result of 15 megatons (1,000 times Hiroshima) even surprised its designers, both by strength and by the devastating level of radiation released. However, Teller’s impetus did not stop there either. I wanted more, Much more. It was then that one of the most delusional and terrifying projects of nuclear history emerged: the Sundial Project. Designed by Teller and his colleagues from the Livermore Radiation Laboratory, the plan proposed a new destruction scale: no already kilotons or megatones, we entered In the gigatons. A couple of brothers. They were designed Two weapons: Gnomon and Sindial. Gnomon would act as “primary”, with a detonation of 1,000 megatons aimed at detonating Soundy, which would reach a power of 10,000 megatons, that is, 10 gigatons. For placing it in perspective, he thinks again The image of the beginning. Well, the figure exceeds 200 times the tsar bomb, and almost does not fit in the conceptual framework of the physics of conventional explosions. The potential apocalypse. The logic behind Sindial overflows any traditional calculation. To such powers, the laws of escalation of destruction They lose any validity: The heat, pressure and energy released would be so monstrous that, a priori, they would open a hole in the atmosphere. In fact, A report Del Bulletin of the Atomic Scientists pointed out that a pump like a sundial, detonated about 45 kilometers of altitude, could cause fires in an area of the size of France. The death toll would be unthinkable, not only because of the immediate explosion but by global radioactive sequels. Hiroshima, with 140,000 victims, would be a sigh against cataclysm that would represent Sindial. It was not science fiction. Although it might seem like a laboratory fantasy, the Sundial Project It was not a joke or an eccentric occurrence. Declassified documents and historical analysis indicate that Livermore’s team worked seriously For years in the development of Gnomon, with concrete plans to test it in the Redwing operation of 1956. That test was canceled, but the mere existence of the plan shows to what extent the fear, scientific ambition and deterrence had pushed the superpowers to border the abyss of the unacceptable. Echoes of Sindial. Suindial never materialized, but his mere conception forced A critical reflection In American politics. The growing destructive power of these weapons overflowed not only military strategy, but also ethics, logistics and land physics itself. While many ruled out their tactical utility for being impracticable (a pump of such dimensions was impossible to launch), its potential as an instrument of symbolic terror was enormous. As with The TSAR pumpits value was more political than operational: a floating threat that showed how far a nation could go if I wanted. Monster in the shadows. Finally, the Soundal project is It was diluting between political restrictions, international treaties and practical sense (without serving as precedent). The Ratification of the treaty Partial prohibition of nuclear trials in 1963 was a brake on atmospheric tests, which in practice made it impossible to continue advancing in the development of extreme performance weapons. The strategy then went on to favor smaller, portable and operational multiple eyelets, leaving behind the vision of total apocalypse that represented Sindial and its cousin Soviet sister. Imagine the unimaginable. What’s doubt, today sundial is just a footer … Read more
