reverse engineering with an unprecedented weapon

In wars, innovation is rarely born in a vacuum: it has often emerged from carefully observing the adversary. Throughout history, some of the most profound military transformations came not with entirely new weapons, but with the reinterpretation of existing technologies that changed hands. Now, in the 21st century, when the AIthe unmanned systems and the industrial production accelerated speed sets the pace of the combat, that old dynamic has once again taken center stage in a way that is as unexpected as it is revealing. The debut of American kamikaze drones. Yes, the United States attacked Iranian territory within the framework of Operation Epic Fury together with Israel, but what was truly unprecedented was not the magnitude of the air offensive or the coordination between both countries, something that we saw very few months ago in the same scenario, but the debut in combat of the LUCASthat is, the long-range kamikaze drones used for the first time by US forces. Launched from the ground by Task Force Scorpion Strikecreated specifically to introduce this type of capabilities in the region, the LUCAS acted as loitering munitions capable of flying long distances, staying in the zone and launching against their target in a single use. Their low cost, around tens of thousands of dollars per unit, contrasts with the price and production complexity of traditional cruise missiles, which allows them to be used in sufficient number to saturate defenses, coordinate network attacks, and maintain human oversight while operating with partial autonomy. For the first time, Washington was not only talking about cheap drones as a complement, but was actively integrating them into a real campaign against a sovereign state. The weapon returned to its creator. The strategic key to the attack lies not only in the technology, but in its origin. It we count some time ago. He LUCAS design part directly of the Iranian Shahed-136the same model that Tehran has employed for years in the Middle East and that Russia has used brutally in Ukraine. After obtaining a copy, the device was analyzed and reengineered by American companies, adapting it to their own standards and a more networked architecture. In essence, Washington used one of the oldest practices of warfare to bomb Iran: reverse engineering. It was not just about copying a platform, but about appropriate your logic operational (cheap weapon, long distance, volume versus exclusive precision) and turn it back against whoever popularized it. The result is a investment symbolic and even doctrinal: The country that had perfected the use of low-cost drone swarms became the target of its own reinterpreted strategic model. Tactical surprise and demolition. If we expand the frame of the photo, the use of drones was integrated into a much broader offensive based on precise intelligence and extreme timing. He told in a report the new york times that the CIA and the Israeli services managed to identify a meeting from top Iranian commanders in Tehran, including the supreme leader, which allowed the timing of the attack to be adjusted to maximize the initial impact. The combined operation drones, cruise missiles, long-range artillery and a massive aerial surge that sought to neutralize anti-aircraft defenses and dismantle the chain of command from the first strike. The result was the removal of key figures of the Iranian political-military apparatus and obtaining air superiority in a matter of hours. In this context, the LUCAS did not act in isolation, but as part of a distributed attack architecture that combined saturation, precision and speed to prevent an immediate coordinated response. Cheap drones vs millions. The use of LUCAS also showed a deeper trend that the war in Ukraine has pontificated: the growing vulnerability of advanced air defense systems to cheap and numerous platforms. Iran had demonstrated that even the most sophisticated defensive architectures can be overwhelmed by waves of relatively simple drones. The United States now applied that same logic, exploiting the cost-effect relationship to impose pressure and force the adversary to spend much more expensive resources on interceptors. If you will, the long-range kamikaze drone stops being a weapon of peripheral actors and becomes a fully integrated tool in the arsenal of a superpower, altering the traditional equation between cutting-edge technology and volume of fire. From Rome to the missile age. The reverse engineering employed by Washington is not a modern anomaly, but rather a historical constant. In ancient times, Rome copied Carthaginian vessels to build your fleet. In the Middle AgesThey used siege machines captured, and already in World War II, rocket and bomber programs were fed by enemy technology and scientists. One of the most famous cases was that of German V-2 ballistic missile developed by Nazi Germany at the end of World War II. Both the United States and the Soviet Union captured rockets, plans, and scientists. Washington joined Wernher von Braun in its space program, while Moscow did the same with its own equipment. That reverse engineering was the direct basis of the missile programs and, later, the space race. And during the Cold War. Also, because both missiles and guidance systems changed hands to be disassembled and reproduced. One of the most famous cases was that of the strategic bomber B-29 Superfortress. When several American B-29s made forced landings on Soviet territory, the USSR dismantled them piece by piece and produced an almost exact copy: the Tupolev Tu-4. It was, once again, an extreme exercise in industrial reverse engineering, to the point of replicating even defects in the original design. The pattern, as we see, repeats itself: capture, study, adapt and improve. What changes is the speed and technical complexity. In the case of the LUCASthat cycle closed in the 21st century with remarkable speed, also integrating autonomous coordination and network warfare capabilities that multiply its impact. The practice is ancient, but its execution is contemporary. A new stage. He attack on Iran marks a turning point because it includes for the first time the United States as an active user of long-range … Read more

they are gentrifying in reverse

A curious phenomenon has been quietly repeated in recent years in the wealthy neighborhoods of the northwest of Madrid, where large mansions located on plots valued at millions of euros are a regular part of the landscape. It involves the replacement of these large single-family mansions with private complexes made up of smaller single-family houses, built in the space previously occupied by large mansions. At the urban level there does not seem to be a big change. However, as the councilor of the Socialist Municipal Group of Madrid Antonio Giraldo in your X profileit is an unprecedented gentrification process that is silently being implemented in the richest neighborhoods of the capital. Same space, more population. As Giraldo explains in your threadeach of these operations occurs within a perfectly legal framework since it does not require any action to reorganize the territory or reclassify the land use since it continues to be a single plot and contains single-family homes. The type does not change, just change the number. To make the miracle of loaves and fishes possible in a real estate version, it is enough to enable a private street that provides access to the new single-family houses within the plot. The only difference is that, instead of having a single construction in the form of a huge mansion occupied by a single family, the space is redistributed into several smaller single-family homes, occupied by separate families. No complex legal requirements. Since there is only a rearrangement of space within the plot. the only requirement that marks the General Urban Planning Plan of Madrid is to present a detailed study to the city council. As in reality no regulations are being breached because the nature of the homes to be built is not being changed, in reality the procedure remains almost an informative formalism. However, what is actually being achieved is to increase the density of the resident population because, instead of having a single-family home of 1,000 m2 in which one family lives, there are now five single-family houses of 200 m2 with five families occupying the same space. Rich, but not so rich. The gentrification of wealthy central neighborhoods in the capital is already a reality. The traditional inhabitants of neighborhoods like Salamanca already they are being forced to move to other more remote areas due to the increase in the price of luxury housing in those neighborhoods driven by the arrival of US millionaires and Latin America. This has made the luxury residential neighborhoods on the outskirts, traditionally inhabited by the ultra-rich who had built their mansions in a quiet neighborhood with few inhabitants, become the new destination for these new neighbors who are not rich enough to buy a mansion, but are equally well-off. The density problem. The big problem of increase density of a residential area is that the infrastructures were not designed for this change. Precisely for this reason it is not allowed to build floor blocks on them. The residential neighborhoods of Madrid and the majority of large cities in Spain have narrower streets, less parking capacity and public transport networks sized for use by a small volume of people. If suddenly the population multiplies by five, services become strained and life in those neighborhoods is no longer as calm and relaxed as it used to be. Streets with more traffic and traffic jams, insufficient public transport frequencies, insufficient health infrastructure and school places, etc. “Inverted” gentrification. While usually the arrival of new neighbors of high purchasing power raised the price of housing to the point of making it inaccessible to its inhabitants, in the residential neighborhoods with high purchasing power of Madrid the reverse process is taking place. Real estate developers are putting pressure on the owners of large mansions to demolish them and build smaller, more profitable luxury homes for millionaires who cannot afford to buy a 1,000 m2 home in that area, but can afford to buy a 200 m2 home and share space with four other neighbors. It doesn’t work in Barcelona. In the upper area of ​​Barcelona, ​​with a layout of huge plots on which enormous mansions were built, an attempt has been made to apply the same model of replacing large mansions with luxury houses, but smaller. However, the urban policy of the city of Barcelona does not interpret in the same way that practice. For the Catalan council, the change does not simply represent a rearrangement of the built volumes as happens in Madrid, but rather they take into account the impact of the modification on the neighborhood and recognize “the need to maintain the character of a consolidated neighborhood.” In Xataka | If you don’t have the money to buy a house, there are several towns in rural Spain that have something to offer you Image | Unsplash (Fabian Wiktor, Alim)

Galapagos tomatoes are ‘evolving in reverse’. And that is spectacular news.

The Galapagos Islands They are the living laboratory of evolution. It was there that Charles Darwin observed the differences in finches that cemented his famous theory of natural selection and that laid new foundations for the evolution of the human species. Now, almost 200 years later, these islands are back in the news, but for a surprising reason: a species of wild tomato seems to be turning the evolutionary clock. But the most important thing of all is that this involution in vegetation opens the door for us to understand how small changes can give us a wide range of possibilities in human pharmacology. The discovery. A new study published in Nature Communications has discovered that, while evolution followed its “normal” course on the oldest islands of the archipelago, the tomatoes on the younger, more hostile islands have “devolved.” And they are actively recovering a chemical trait that their ancestors lost millions of years ago, something that doesn’t seem too logical. And it is not logical because we all have in mind that changes are always for the better to adapt to a specific environment. But these plants are giving us a completely different perspective than what Darwin saidalthough it has important applications especially in pharmacology. A chemical twist. The study of ‘involution’ focuses on the steroidal alkaloids (SGAs), powerful compounds that plants of the Solanaceae family (such as tomatoes, potatoes and eggplants) use as a natural defense. These compounds have a key characteristic: chirality. This means that a molecule can exist in two forms which are mirror images each other, as if it were our left and right hand, or even a reflection of ourselves in a mirror. The two ways are the following: The modern “tomato type”: mainly produces the 25S isomer. The ancestral “eggplant type”: produces the 25R isomer. In this way, the study is seeing that although years ago it was normal to produce 25R, it was later changed to producing 25S. Now, evolution is taking off again to return to the most ancient. Behind this is an enzyme called GAME8 that has dictated what type of chemical defense each plant produces. In fact, the researchers showed that by modifying just eight amino acids of the tomato GAME8 enzyme, they could stop it from producing its 25S compound and make exclusively the ancestral 25R. It is literally an evolutionary switch. Evolution in ‘reverse’. This is where the plot thickens. The researchers analyzed the Solanum cheesmaniaea wild tomato endemic to the Galapagos. And what they found challenges the idea of ​​linear evolution: On older islands, such as St. Kitts, tomatoes almost exclusively produce the ‘modern’ 25S isomer. On more modern islands like Isabela, tomatoes have changed and accumulate high levels of the ‘ancestral’ 25R isomer. It’s not that these plants were “left behind.” The data suggest that their immediate ancestors produced 25S, but the unique environmental pressures of younger islands have favored mutations in their enzyme. GAME8 that they have made it return to produce the ancestral compound 25R. It is a clear case of reverse evolution. Because. Younger islands are more arid and hostile environments, and science suggests that this ‘ancient’ chemical cocktail could offer better protection against pathogens or herbivores specific to that inhospitable environment, or even help the plant in different soil conditions. The important thing. Beyond being a botanical curiosity, chirality is a fundamental concept in pharmacy. One isomer of a drug may be therapeutic, while its mirror ‘twin’ may be harmless or, in infamous cases such as thalidomide, tragically toxic. Understanding how nature has managed to make a single enzyme (GAME8) change its product from 25S to 25R through a few mutations is a great advance for biotechnology. We could, in theory, use this knowledge to engineer crops with specific alkaloid profiles, creating more resistant plants or, conversely, eliminating anti-nutritional compounds.

The US has realized how risky it is to continue pressing China. His reverse looks for a “face to face”

The US is softening its export restrictions to China. In early July, the administration led by Donald Trump allowed Nvidia to sell Your H20 GPU To its Chinese clients. At the time This movement surprised us because it clearly indicated that an obvious change was consolidating in the US strategy in front of the nation governed by Xi Jinping. According to the newspaper Financial Times This relaxation of export restrictions to China seeks to “avoid damaging trade negotiations with Beijing.” And it is presumably this week US and China will resume their negotiation to establish the rules that will resolve their future commercial interests. As expected, this rudder of the US administration favors the interests of Nvidia, AMD, Broadcom and other companies, but not all members of the Trump administration support this initiative. According to Financial Timessome White House advisors are pressing the government to maintain their blockade to China. Nvidia needs TSMC to manufacture 300,000 H20 chips for China Donald Trump wants to meet “face to face” with Xi Jinping before he ends this year, again according to the information he has Financial Times. The intention of the US president is to file roughness with his Chinese counterpart with the purpose of promoting negotiation in commercial matters that both countries have maintained for many months. Just a few hours ago they have gathered in Stockholm (Sweden) Scott Besent, the US Treasury Secretary, and He Lifeng, the Vice Prime Minister of China, so it is evident that the negotiation follows its course. After many months of uncertainty the current scenario clearly benefits Nvidia. The company directed by Jensen Huang saw its survival in China threatened by The sanctions approved by the Department of Commerce from the US, but This volantazo changes everything. And its protagonist is the chip for artificial intelligence (AI) H20. The reception that Chinese clients of Nvidia initially gave to this GPU was very good despite the fact that the capabilities of this chip are clearly inferior to those of the other proposals for this company. After many months of uncertainty the current scenario clearly benefits Nvidia In fact, initially the Department of Commerce allowed its sale in China because this integrated circuit met the restrictions it had imposed. And despite its limitations its sales in China grew by 50% quarter to quarter since it reached this market in mid -2024. Everything was complicated for Nvidia in the middle of last April. And is that the US Department of Commerce imposed new restrictions To the export to China of the H20 GPU, which in practice caused this chip to stop reaching the Chinese clients of this company. This news sank Nvidia’s actions by 6% because it could no longer address the commitments linked to the H20 GPU it had acquired. Among the Chinese customers who had bought it Large amounts of this GPUand presumably planned to continue doing it, were Tencent, Alibaba or Bytedance. Finally Nvidia has achieved That the Department of Commerce review its regulation and allow you to sell the H20 GPU in China again. Surprisingly this scenario has put Nvidia in trouble. And, once again, the reception of the H20 GPU in China is being so good that this American company has run out of units. According to ReutersNvidia has commissioned TSMC for the manufacture of no less than 300,000 units of this chip to be able to respond to the current demand from China. Blessed problem. However, the company’s engineers have been working on A new GPU with Blackwell microarchitecture The latest generation that is intended to occupy in China the place of the H20 chip. In fact, presumably TSMC began in June the production of The B30 GPUwhich is how it seems to be called. What we know at the moment is that this chip for AI will be less capable than the H20 GPU, as is logical, and also that its price will move Between 6,500 and $ 8,000. For domestic users it is a lot of money, but in the field of professional GPUs for AI it is a moderate price. In fact, the H20 GPU costs between $ 10,000 and $ 12,000.
