Ukraine has turned drones into armed soldiers against Russia. It is no longer necessary to “sacrifice them” because they carry launched

by

That the war in Ukraine has become the largest field of technologies and war artillery. out of any doubt. However, if you had to name a single protagonist, that would be the use of drones as “animals” of Combat for everything. The Ukrainian country, in fact, has become one of the Great industries of the planet in the sector developing many of the most advanced (and important, economic) prototypes to date. The latest: turn drones into authentic soldiers of the future holding launched in flight. Aerreo launches. As we said, Ukraine has reached a new mile With a launchersuch and As he revealed The Ukrainian company Wild Hornets, specialized in military technology. The images, disseminated by the company itself in Your telegram channelThey show what they describe as the “exclusive death” of a Russian soldier reached by one of these devices on the Novopavlivka front. The attack was carried out by the Bulava Unit of the separate presidential brigade, and they did it by adapting their drone “Queen of Hornets”(A heavy model usually designed for bombings) to carry and shoot a precision grooved from the air. The operation, in addition to having tactical success, served as proof of concept and exhibition of the modified design, whose stability when triggering resolved one of the main technical obstacles: the recoil. Mortal precision. After the videos and the exclusive, Diego RodríguezRecognition drone operator in the body of unmanned systems, He expressed his astonishment Because this technology has not been implemented before, underlining its technical superiority against Kamikaze drones. In the expert’s opinion, the throws from drones allow faster, accurate and silent attacks, since Granada rounds fly faster and more reaching, reducing the enemy’s reaction margin and exposure to electronic countermeasures. The reason? The drone can shoot, retreat and recharge, multiplying its usefulness Without losing unity In the attack. Faced with the traditional explosive drones that emit noise and give the enemy time to protect themselves, the granades projected from the air arrive almost instantaneously, making them impossible to dodge them. Without anticipation. Another expert, in this case Vadym Feshchenkoex grenadier converted in drone operator, stressed that this innovation completely alters the defensive habits of the enemy. Russian troops have learned to observe the movements of drones to anticipate when they will release their explosive load, but a drone that shoots in full flight eliminates that reaction window. Feshchenko also highlighted the weapons versatility employee, pointing out that some modern launch projectiles have the capacity to drill up to seven centimeters of armorwhich expands its applicability against fortified vehicles and positions. As these systems multiply, it is likely that the simple sound of a drone forces enemy soldiers to retire or hide, increasing the psychological and tactical impact of the device, also as a deterrence In full fray. From standard prototype. That said, what we see is an evolution. In September 2024 already Videos circulated of tests where Ukrainian FPV drones carried RPG-18 launches. While then rudimentary prototypes were considered, their possibilities were already evident. As counted in Ukrainian media, a collateral advantage of this system is Risk decrease For technicians and engineers who must manually assemble kamikaze drones, exposing themselves to injuries that are rarely made public. In this regard, the partial automation that allows an armed and reusable drone represents a step forward in terms of operational security. Adaptive Engineering They remembered in Insider That although the first use in combat has been attributed to Ukraine, the idea of ​​mounting launched in drones had already been proposed in 2021 through the Display Belarusian Design Cabinet during a Russian military exhibition. The most complex technical challenge was drone stability When shooting, since most quadcopters are too light to support the backward. However, The “Queen of Hornets”due to its size and reinforced design, it seems to have resolved this obstacle: in the Video widespreadno instability is observed after the shot. In parallel, Ukrainian engineers have managed to convert even agricultural drones such as the DJI AGRAS T30 (originally designed for fumigation) on attack platforms, equipping them with PKM machine guns and launched Bullspike-Atcapable of attacking tanks, self -propelled artillery and fortified positions. A radical transformation. As we told at the beginning, the war in Ukraine is changing many of the war concepts that were in the battles of the past. But above any other actor, the introduction Drone successnow even shooting grenades from airmarks a before and after in the development of the technological war. While traditional artillery and heavy weapons continue to play an important role, the miniaturization of fire power and its integration into reusable and precise drones represents a strategic advance that combines efficiency, lethality and operational economy. The question now is not whether this technology will be extended, but rather how fast Ukraine can produce it in mass and how Russia will respond to a threat that becomes increasingly silent, unpredictable and difficult to stop.

How protein cult has turned the muscle into the new social networks trend

by

In the Basilica of San Pietro In Vincoli, in Rome, there is a sculpture that attracts the attention of many people for a simple detail. The work, Miguel Ángel’s “Moses”, the sculptor carved a small muscle on the forearm that is only activated by lifting the little finger. This almost invisible gesture, but essential for Michelangelo shows the subtle force and control. Today, centuries later, the bodies defined as if they were sculpted are trend. But this time, it is not about marble or art, but of protein, supplements and extreme routines. In the Chic Protein era. A new phenomenon that has gained strength in recent years, but now is the trend that marks on social networks. In 2023, products enriched with proteins had taken the supermarkets. From yogurts to snacks, the industry promoted the idea that greater protein consumption is synonymous with health and well -being. Now, that obsession has moved to the toned bodies: figures like Ashton Hall, Famous for its morning routineit is a clear example of that ideal of healthy life and sculpted body. A new welfare mantra? In the third season of The White Lotus, Saxon Ratliff, a character obsessed with exercise and body image, embodies perfectly This contemporary obsession with proteins. Interpreted by Patrick Schwarzenegger, the son of the iconic Arnold Schwarzenegger, Saxon not only loads with his personal blender so as not to miss his protein shakes, but also consumes popcorn enriched with “Khloud” dust of Khloe Kardashian, an obvious satire of the marketing of hyperproteic products. Saxon is not just a character obsessed with his muscles; It is a fitness symbol turned into pop culture, where protein blender is as essential as mobiles and smoothies are the new fashion coffees. Beyond the screens. This fictional portrait is a reflection of what happens with the boom of hyperproteic products, is it really necessary to consume 200 grams of protein in a shake, as Saxon does in the fourth chapter? Science has offered different perspectives. On the one hand, the main dietitian of MAY CLINICTara Schmidt, has affirmed that protein needs depend largely on the lifestyle, weight and health history, so he cannot affirm with certainty what is the ideal amount. Although it is recommended has pointed out To vogue that excess protein can cause inflammation and affect intestinal health, counteracting the initial benefits of these hyperproteic products. The path to (almost) perfection. Even the fashion world has embraced this new body form. Designers such as Demon and Hilary Taymour have presented collections that emphasize muscular silhouettes, evidencing how fashion adopts and amplifies the body ideals promoted by the culture of well -being, According to Vogue. However, not only fashion has imposed the standard, the viralization of medicines to lose weight as Ozempic and Wegovydeveloped to treat type 2 diabetes, they have become rapid weight loss products. And in the meantimephenomena like Skinnytok They promote restrictive diets and extreme exercise routines, with millions of visualizations that glorify thin and toned bodies. Social networks have amplified the obsession with the sculpted bodies, turning each physical transformation into a viral show. The distorted mirror. In this era where the body is the new canvas, body dysmorphia He has found A perfect breeding ground to spread. This disorder, characterized by an obsessive concern for defects perceived in the body, has reached alarming levels on social networks such as Tiktok and Instagram. In these platforms, filters, edited images and constant comparisons They have exacerbated The distorted perception of the body, especially among the youngest. A Health report has pointed out That the constant exposure to hyperdefinid bodies and perfect skins can lead to eating disorders and compulsive behaviors related to exercise. The psychologist specialized in TCA, Sara Bolo has explained to this medium that the worrying thing is that many of these apparently “healthy” behaviors hide eating disorders disguised as fitness culture. We see more and more full gyms and more people obsessed with not skipping a meal or training, and that is where the problem begins. It is not the exercise or healthy eating that is wrong, but the rigidity with which these practices are followed. In addition, he has warned: “In the end, it is not so much to take care of the body as forcing it to fit into an unreal mold that we see on social networks.” The end point. In a world where the image weighs more than the essence, where bodies are molded as sculptures and extreme diets disguise themselves as self -care, the inevitable question arises: to what extent are we really taking care of our bodies or simply molding them to fit into an unattainable mold?

Without light at home, many Spaniards turned to another “shelter” for hot dinner or load the mobile: their car

by

Spain collapsed. In five seconds, The Government tells us60% of the electricity consumed at that time was lost and all kinds of electronic devices went black. Then we understood to what extent we depend on electrical energy. Without the possibility of plugging into the network, the batteries began to quote and, above all, they showed us the importance of having a Small electric survival kit. Because how can we load the mobile when we don’t have electricity? The question also resonated at a server’s house. First came the disappointment with the already known answer to the question “Didn’t you have some PowerBanks?” Then, a light bulb was lit: “We always have the car.” A shelter Luckily, we did not have to go down to the garage but use the car like a gigantic external battery would not have been a bad idea. In fact, it is not necessary to have an electric car although this technology allows us to even be more flexible. The USB shots From cars with combustion engines they generally serve us to plug small electrical devices and can get us out of trouble. Simply start the car and connect to one of its ports or take the lighter. In this case, the most basic and obvious option a situation like the one that We have lived in Spain on April 28, 2025 It is to load the mobile phone or an external battery that already helps us keep the electrical devices alive. Generally, cars’s USB shots are not especially powerful, so we will need to spend more time load the mobile phone that at home and surely we will have to forget the fast charge. As we will see, there are some exceptions to this. If your car is already a few years old, The normal thing is that you use a USB 1.0 or 2.0. This limits the load to 500 mA. With current phones, the load will be extremely slow or, simply, it will slow down your download if we are using the mobile phone at that time. If the car is more modern, it is easy for USB-C shots to deliver 5W of power onwards, which is more than enough to load a current mobile phone. Another solution if, as we said, the car is a few years on it is to use an adapter for the tambo. In this case, It has a voltage of 12 volts In direct current and its amperage is 10 A. The maximum power in this case usually reaches 120W so the maximum power to which we can load the car will depend on the adapter used. In stores like Amazon It is easy to find products for little money with up to 30W So we can load a relatively fast mobile phone or, if necessary, to a laptop if necessary. That is, it is not a bad idea to carry an adapter of these in the car. Not only is it a matter that in the case of a blackout we can load the phone, it is also interesting if, for example, we have suffered a breakdown and we have to wait for hours until we get an assistance. The possibilities multiply with an electric car. Currently, most of those sold in the market arrive with V2L (Vehicle to Load) technology, a standard of Bidirectional load that allows to load most of the electronic devices we have at home because, simply, it makes our car a domestic plug. Click on the image to go to the original tweet Click on the image to go to the original tweet To get an idea, the car becomes a huge battery with wheels that can provide us with electricity to 3.4 kW. That is, we can easily plug a microwave and, for example, dinner hot despite being in the middle of a blackout. Again, it is an interesting solution if we want to spend an night away from home and we want to make a timely use of a high consumption device like this. Keep in mind that a device such as A microwave can easily overcome 1 kW of power to function. Therefore, we could not start it without this type of V2L technology. Again, it is an interesting option without the need to face a blackout. If we want to spend an afternoon in the field and enjoy coffee after eating, A capsules coffee maker can be the solution. And more useful, we can Take advantage to have an inflatable mattress Wherever we go. The two previous cases are not isolated. Talking to other colleagues who have an electric car, some of them have confirmed that they took advantage of the car batteries to serve various home tools and, in fact, they regretted that in Spain the V2H technology (Vehicle to Home) or V2G (Vehicle To Grid) is not allowed. With the V2H technology You can pour the battery from an electric car to a house. Although in most cases the car itself reserves a minimum percentage that is usually at 20%, this bidirectional load could supply tens of kWh to a house, which can be used to maintain a house for several days. V2G technology allows even launching electricity accumulated in the car to the general electricity network and, therefore, electric cars could act as electric power stores that can be used in emergency cases.

An island in Japan has revolutionized its vehicles. They have turned cow droppings into hydrogen fuel

by

If we talk about hydrogen and mobility, we would possibly have to Add to Japan In the equation. Few companies have tried to make it a real alternative to the electric car like the Japanese Toyota, although it is true that in recent times the idea was Much more than in doubt. An island has shown that technology is still there. Of course, with the invaluable help of tons of cows excrement. The solution in Hokkaido. On the island of HokkaidoJapan, a key region for country production of the countryan innovative project seeks to convert the Hydrogen cow manurethat clean fuel with the potential of feed vehicles, homes and agricultural machinery. With More than one million cows Currently generating 20 million tons of manure per year, this source of waste represents an environmental problem due to its methane emissions and its impact on the Water quality. He Shikaoi Hydrogen Farmlaunched in 2015 by the Ministry of Environment of Japan, addresses this challenge by transforming waste into a sustainable energy resource. As? The manure and urine of cows are Farm collected local and sent to an anaerobic digester, where bacteria break down organic matter to produce biogas and liquid fertilizer. Then, biogas is purified in methane, which later becomes, hydrogen. Sustainable mobility. The plant has a production capacity of 70 cubic meters of hydrogenenough to supply up to 28 vehicles with hydrogen cells per day. In addition to cars, the fuel is currently used In tractors and forklift of the island, whose electrification with batteries is more complex. It is also stored in Canisters that are transported to provide energy to a sturgence fish and Obihiro Zoo. Challenges Several, of course. The main one is logistics, since it must be stored in high pressure tanks, which does so susceptible to leaks and degradation of materials, in addition to requiring specialized infrastructure for transport and distribution. Your acryogenic lmacement at -253 ° C is energetically expensive, which hinders its scalability. In spite of this, the project continues to advance, mainly with subsidies that equate the price of hydrogen with that of gasoline, to promote its adoption in cities such as Sapporo and Muroran. In fact and as we said at the beginning, Japan leads the hydrogen industryalthough the electric cars still They are more profitable than those driven by this gas. Hydrogen from waste. The truth is that the concept of producing hydrogen from waste is not limited to Japan. Other initiatives in the world explore alternative sources such as Pork manurepoultry and even Coconut peels. For example, in Thailand Toyota investigates hydrogen production From chicken excrement. In the United States the University of Illinois developed A METHOD TO MANUFACTURE HYDROGEN With manure, sugarcane residues and corn cobs, significantly reducing the energy consumption of the process. And in Fukuoka, Japan, a wastewater treatment plant produces hydrogen From human wastesupplying a fleet of garbage trucks without emission. All initiatives show that bioenergy from waste can play a key role in the global energy transition. However, the lack of infrastructure and high costs remain barriers for large -scale expansion. Uncertain future. He Project in Shikaoi It is an innovative example of circular economy, where waste becomes energy, reducing emissions and promoting sustainability. However, the viability of hydrogen as an alternative to fossil fuels will depend on technological advances that reduce their cost of production, storage and distribution. Although manure and cow droppings will hardly be the main source of hydrogen in the future, especially worldwide, initiatives such as these can lay the foundations for a new energy industry based on waste recycling, with potential applications in transport, agriculture and clean energy generation globally.

Musk’s political ambition has turned Tesla into an ideological lightning rod. And the whole company is paying

by

Tesla’s action touched its historical maximum at the end of 2024, just in time for Christmas. Since then You just made receiving coala paradox for the leader of the electric transition. From $ 480 to 240. Half. 50% fall (and 15% in a single session last Monday) is no longer a market correction or temporary fluctuation. Is the materialization of the political risk that Musk has accumulated deliberately during the last two years. Musk, with its lights and their shadows, It is an atypical phenomenon and a case study like or not. But he has also starred in his own even more atypical phenomenon in recent business history: the transmutation of an aspirational brand in the object of cultural repulsion for a part of its original client base, as stated The Verge. Tesla built an empire on very specific pillars: Technological innovation Environmental sustainability. A vision of the future techno -optimist. It was a perfect car – figured and literally – for progressive consumers with purchasing power that wanted to signal not only financial power, but avant -garde values. Musk’s political turn has caused a cognitive dissonance too heavy For a good part of this segment. This ideological fracture can be put figures. In California, one of the great progressive bastions and originally the most important market for Tesla, Model 3 sales They collapsed in 2024. In Europe, collapse has been even greateralthough it would be unfair to signal only to Musk’s personal future, since here a perfect storm has come together. They are more typical figures of A brand exodus – Here we can point to Chinese cars, but in the United States not – than a simple sector recession. Especially because even in Europe we have seen A growth of 34% in electric car sales at this time. The most visible demonstration of this brand crisis is the spontaneous emergence of an ecosystem of embarrassed owners. From apology stickers (“I bought it before Elon went crazy”) to the replacement of the Tesla logo with other generic badges. They are drivers who seek to dissociate their creator’s car. The protests have climbed to pure and hard vandalism, with concessionaires Tiring in Oregon, Molotov cocktails in Colorado and some Cybertruck on fire in Seattle. Tesla has become An ideological lightning rod. Meanwhile, competition has taken advantage of that vulnerability. Hyundai, Kia, GM U Honda (let’s mention Chinese brands on this side of the Atlantic) have been launching electrical alternatives perhaps not as painting as a tesla, but already attractive and more or less reasonable prices. In this equation There is a blind spot: Musk itself. His political ambitions and his parallel agenda with Trump have eclipsed their business vision. Tesla needs more than ever its affordable model – about $ 25,000, The repeated and deformed promise since 2018– To compete against byd, omoda, Jaecoo and company. But Musk is aspiring to something much older, maybe even too conceptual, such as Humanoid robots. Or with the promises of robotaxis that do not finish arriving … while Waymo already operates real fleets of autonomous taxis. Tesla’s technical credibility has also worsened. The promise that all cars manufactured after 2016 contained the necessary hardware for totally autonomous driving turned out to be true. Musk He admitted that they will have to replace on board computersa process that he confessed “painful”, and now faces collective demands for deceptive advertising. Tesla was, is and will surely be the king of the electric car in many ways, but something has changed lately. Trump can convert the White House into a Tesla dealership and proclaim in your social network Your absolute support to Muskbut You cannot reverse financial physics. The destruction of value has been monumental: 800,000 million dollars of stock market capitalization and 100,000 million of Musk’s personal heritage have evaporated in less than one semester. Even some historical shareholders, loyal to Musk, They have sold mass actionssuch as Robyn Denholm (the president of the Council) or James Murdoch (son of Rupert). There is a fire in Tesla, but that is not too worrying, every company happens at some time. The problem is that it is self -induced. Tesla will survive, surely, it has a solid cash position and hard -working economies. We are no longer in 2019. The real question is whether you can recover your old statusthat of Visionaria company, while its founder is still determined to sacrifice it on the altar of its political aspirations. The divorce between Tesla and a part of its original customer base seems difficult to reverse in the short term. The maximum irony of this story may be that the greatest enemy of the original mission of Tesla – to school the world transition towards sustainable energy – turns out to be Musk itself.

In 1958 France approved a nuclear plan to defend itself without the US. Russia has turned the plan into a reality for Europe

by

It happened in 1958, but now it cannot be more relevant. Then, General Charles de Gaulle had a vision of the need for France to maintain some strategic dependence by launching the Nuclear deterrence policy Sovereign, a kind of nuclear umbrella arguing that, although the United States was an ally, its interests may not always coincide with those of Europe. It has spent more than half a century and, suddenly, the continent has set the French nuclear doctrine against American uncertainty. The possible extension of the shield. It was French president Emmanuel Macron who He raised the possibility to associate French nuclear deterrence with the defense of other European countries. Although its ad It could explicitly spread To other nations. In this regard, the French Defense Minister, Sébastien Lecornu, reiterated that the nuclear arsenal will remain completely Frenchunder the only authority of the president. However, the key issue is whether France could assume a more active role in the continent nuclear defense. The (in) definition. Historically, French nuclear doctrine has been ambiguous with the threat of a massive response if France’s “vital interests” were in danger. However, these interests have never been defined precisely. From the presidency of De Gaulle, France has suggested that some European countries were already de facto, Under your protection. In fact, in 1964 De Gaulle declared that a Soviet attack against Germany could be interpreted as a threat to France. We remember that France and the United Kingdom are the only European nations with nuclear weapons. France counts With almost 300 eyeletsdeployed in airplanes and submarines, while the United Kingdom has approximately 250. Thus, there is a crucial difference: France maintains total independence in the development and operation of its arsenal, while the United Kingdom depends on US technology. Europe thinks about it. Actually, what has really changed in this debate is not the French proposal, but the attitude of the rest of Europe. Until recent United States and NATO. This idea has jumped through the air with the second mandate of Donald Trump, added to his current rhetoric of reduce military support To Europe, which has generated a change of perspective. Countries Like Germany They have seriously considered the option of a European nuclear shield. Moreover, the next German chancellor Friedrich Merz, surprised his allies by suggesting that it was time to open a dialogue with France and the United Kingdom about the possibility of reinforcing European nuclear deterrence. Scenarios for the alleged nuclear shield. Analysts have become more or less according to the time of summarize the options. There is talk of a deployment of French airplanes with nuclear weapons in other countries, Like Germany or Poland. The decision to use them would continue to be in the exclusive hands of the French president, but his presence would send a disjection message. Also of patrol of French nuclear bombers in European borders, as they do in French airspace, and the creation of air bases in other European countries, allowing a rapid deployment of French nuclear forces in case of crisis. The importance of eyelets. We would say that key for obvious reasons. The number of eyelets is a crucial factor. As we said, France has 300 nuclear heads, and together with The 250 of the United Kingdomthe total number would reach 550. The problem: which is significantly lower than Russian Arsenalwhich exceeds approximately 6,000 eyelets (the majority in reserve), although it is often clarified that the deterrence does not depend only on the amount of weapons, but on the credible and fast response capacity. Another aspect under discussion is if France should modify its nuclear doctrine to explicitly include the defense of its European allies within its “vital interests”. Some analysts argue that maintaining strategic ambiguity is part of the deterrence itself, but others argue that a clear statement of commitment would strengthen trust among European allies. The Russian threat. Although France has M51 missilescapable of reaching Moscow and other great Russian cities with enormous destructive power, Moscow’s ability to respond is, what is much greater. According to estimates in Russian media, a single Missile “Satan II” It could “atomize Paris In 200 seconds“, which underlines the risks of a direct confrontation. The problem lies, in addition, that Russia, given its geographical extension, could resist a prolonged nuclear exchange, while France lacks that strategic advantage. This asymmetry in the ability of mutual destruction raises doubts about the effectiveness of French deterrence in case of a conflict with Russia. If the “yes” occurs. In any case, what seems clear is that if France manages to expand its nuclear role within Europe with the support of the United Kingdom, this would represent a crucial step towards the strategic autonomy of the EU. The deployment of combat aircraft with nuclear capacity in Eastern Europe would not only strengthen the defense of the continent, but would send a clear political sign of unity and determination to Russia. It would be to see, of course, what would be Moscow’s reaction.

This fly larva turned his ass into the head of a little one. The big question we have now is how it will be adult

by

When we think of camouflage in nature, images of Octopos that melt with the seabed, of SEPIAS or chameleons. There are other tactics to confuse possible predators, such as Butterflies that mimic patterns in the wings to confuse birds or Palo insects. But there is an even more committed case to go unnoticed: that of a flip larva that has turned its butt into the head of a termite. And it works so well that the termites until they feed. Fluke. What seems an adorable creature in the main image is, in reality, the rear of a blue fly larva. It has false antennas, but also false eyes, an impressive morphology adopted with a single objective: to confuse the termites. And the finding has been made … by chance. Researchers from the Institute of Evolutionary Biology, the CSIC and the Pompeu Fabra University were studying butterflies and ants in the Anti-Atlas mountain range, south of Morocco. However, like They explain In the publication of the IBE, as the butterflies did not fly due to the heavy rains, they began to look for ants. “When we lift a stone, we found a termiter with three fly larvae that we had not seen before.” Shut mask. They themselves affirm that it was a “casual finding”, but really special because, after it, they made three more expeditions in the area and, “despite lifting hundreds of stones, we only find two others, together in another termitter.” In it study Published in Current Biology, researchers develop their surprise with these larvae that have developed “a unique costume”. Located on the back of the body, the bluefly larva shows a “termite mask” with a non -functional head that has an antennas, palps and eyes extremely similar to those with a great trine harvesting. Those eyes have a function, but very different from what we might think: they are the holes for which the larva simply breathes. Twin. As they explain, most termites live in extremely dark environments on termiters at meters deep, so they do not need eyes at all. The harvesting termites, however, go to the surface to collect grass and have functional eyes, something that these larvae mimic with their spiracles. 3D camouflage. The specimens are curious, but they would really have to define them as fascinating due to two extremely unique details. One is that they not only have antennas in that false head, but throughout their body, as if they were tentacles. Researchers estimate that it is something that facilitates simultaneous communication with several termites inside the termiter. As you don’t see there, the termite that rubs to the “narrow” larva the tentacle of the false termite and thinks “ok, is mine.” But … do they only use touch? The truth is that not because, apart from being felt, the termites have a unique aroma that allows them to identify themselves as the same colony in the galleries of their home. And here comes the other fascinating detail: the larvae imitate that aroma and smell exactly the same as the rest of the termites. Each colony has a distinctive aroma, something that these larvae also have and that researchers have described as a “chemical costume.” They even give it porridge. “The larva is not only tolerated, but constantly communicates with the termites,” says Roger Vila, one of those responsible for the finding. He also speculates the possibility that the termites themselves feed the larva (through their functional head, yes), but it is something they are testing. In one of his photographs you can see that possible mouth -to -mouth food. Accelerated evolution. Vila comments that it is not so weird that there are flies that are made by other insects to carry out forms of social parasitism. For example, humpback flies also imitate the termites, but in that case they are adults, and not the larvae, the protagonists. It also indicates that the common ancestor between both flies dates back to more than 150 million years ago, “much more than what separates human beings from mice, so we could affirm that we have discovered a new case of evolution of social integration,” he says. In addition, he points out that the blue fly larva would have evolved very quickly to adopt these forms. Complications. Vila emphasizes that discoveries like this help to be aware of everything we do not know about the diversity and specialization of insects, but also comments that studying these laboratory larvae is something that seems extremely complicated. The larvae studied ended up dying without reaching metamorphosis in the laboratory, which indicates that, either recreate the conditions they have in the termiter in the desert is crucial – something very difficult – or there is some other element of the nest and the symbiotic relationship between species that is crucial for the survival of the specimens. We will see what they end up discovering, since now the mystery is not only to know if it is a unique larva, but how it will be in its adult form.

To build the longest world bridge, China turned to a peculiar material: bamboo

by

Although Saudi Arabia and Arab Emirates are immersed in a particular war for have the most beast buildingstalking about megaconstructions is to automatically look at China. The Asian giant has some of the works more tremendous, impossible bridges and even Higher abandoned skyscraper in the world. And one of those pharaonic constructions is the Hong Kong-Zhuhai-Macao bridge. With a length of 55 kilometers, it turns out that it is not only formed by steel and concrete: the secret ingredient is bamboo. And according to those responsible, continue like the first day. The bridge. After six years of planning and another eight of construction, in 2018 China opened the imposing bridge that connects Macao and Zhuhai. Its 55 kilometers, 6.2 of them underground, allow to convert a trip that previously lasted three hours into a ‘walk’ of just 30 minutes. And something that resonated in its day was the 420,000 tons of steel (which would be equivalent to 60 Eiffel towers), its more than one million cubic meters of concrete and the flexibility necessary to support typhoons and earthquakes. It is a barbarity, with an underground stretch that disappears and emerges from the sea It looks like a ship, but it is one of the two inputs/exits of the sea Bamboo. It turns out that the mixture added a plant: bamboo. And it is something that is not so weird, since, as we can read In South China Morning Post, China is the largest bamboo producer in the world and is something to give way. In the aforementioned bridge, this element was used on the panoramic platforms that are found throughout the same and the official newspaper Science and Technology commented a few days ago that, after six years installed, these panels have resisted sunlight, typhons and The corrosion of seawater, keeping “as solid as ever.” One more element. Lou Zhichao is a member of the Bamboo Research Institute of the Forestry University of Bamboo and pointed out that, apart from in China, bamboo occurs mainly in developing countries, which gives China a unique advantage and position to the time to process this bamboo. His team, in fact, has been developing more advanced technologies to process bamboo a decade, causing the process to emit less co₂ while encouraging the use of bamboo under constructions due to a relationship between resistance and weight higher than some alloys of some alloys of some alloys of steel. In addition, it can replace wood, plastic and steel itself in some constructions. Bamboo II. Now, although it has interesting properties, it also has a problem: it is prone to decomposition. This means that when bamboo facilities are done, toxic preservatives must be used that make the material much less ecological. The chickens that come through those that come out in environmental matters, basically. And, precisely, the Zhichao team has been working in recent years. One of its latest advances in research is a heat treatment that eliminates nutrients that cause the accelerated decomposition of the material. This allows to reduce its processing time by 50% while increasing durability outdoors without antimoho treatments. Adolfo Suárez Madrid-Barajas airport. You don’t have to go to China to see great structures in which bamboo is clear protagonist. In Spain we have examples such as Madrid airport Adolfo Suárez Madrid-Barajas, in which the roof of terminal 4 is formed by lames 100 mm wide of bamboo sheet. In total, there are 200,000 m² of bamboo with fire resistance and was the ideal material due to the peculiar curved forms of the terminal roof design. It is also a material that was raised for the Futurist Ciudad Oceanix City And the protagonist of the bamboo towers that Paris wants to build for 2050. And scaffolding. Beyond in places as punished as a bridge in such a complicated area and applications in other buildings, bamboo is absolute protagonist in Hong Kong. Specifically, in its skyscrapers, like an exoskeleton that really is a system of Scaffolding During the construction of buildings. For the rest, Zhichao continues to work to expand the use of bamboo as high quality material for several reasons. One because it absorbs 50% more co₂ than common trees. Another because it is estimated that its crop and market benefits some 50 million people throughout the country. And, therefore, he hopes that the government “finance the development of key technologies and reinforce regulation by national and local standards to boost the industry.” Industry tech. Apart from in structures, bamboo is positioning as a material that can be very useful in other sectors. An example is that of consumer technology not as an element that goes within the devices, but as part of the packaging. A few years ago, on a visit to the Innovation Center of Lenovo, They told ushow they were starting to use bamboo in the boxes of their laptops. Bamboo box to the right. On the left too, but after a year underground. The reasons were environmental due to the degradation of their fibers in normal conditions in nature. In fact, it can be buried directly in the garden to use it as fertilizer. In the photo that we leave just on these lines you can see two boxes, one new and one after a year underground, to appreciate its degree of decomposition. And, that sustainability is one of the keys (along with many others, of course) of decarbonization.

To survive in Europe, our Paleolithic ancestors turned to an extreme practice: cannibalism

by

More and more evidence is that our ancestors resorted, at least occasionally, to cannibalism. We are not speaking in this case of other human species, such as Neanderthals, who could have practiced dozens or hundreds of thousands of years but also Homo sapiensthat had already become the only humans in Europe and the rest of the world. New tests. A recent study led by researchers from the Catalan Institut of Human Paleoecology and Social Evolved (IPHES-CERCA) He has shown New indications of cannibalism among humans. They found them in the Polish site of the Maszycka cave, whose remains would go back about 18,000 years ago. Europe in the Magdaleniense. This places the finding in the context of the Magdalenian period in Europe. This period that owes its name to the French site of the Madeleine covers various European settlements between 19,000 and 14,000 years old, they explain in An article for The conversation Some of the members of the study responsible for the study: Francesc Marginedas Miró, Antonio Rodriguez-Hidalgo and Palmira Saladié Ballesté, researchers from the IPHES-CERCA and CSIC. The period follows an era of important changes in Europe, mainly derived from the end of the last era era. The ice setback left behind an ideal environment for a change in ecosystems, and with it the expansion to the north of modern humans. From burial to the table. As the team continues, the Magdaleniense, to others of his cave paintings, also stands out for careful funeral rites, burials “with care and offerings”, at least for some of his dead. Because to others what expected them was the flint of the tools with which they were expired. 63 bones. The new analysis studied more than fifty remains found in the Polish Cave of Maszycka, located near Cracovia. They belonged to half a dozen individuals, both adults and children. The remains found together with animal remains and many with signs of having been manipulated. Despite this, the hypothesis that this manipulation responded to simple funeral rites had not been ruled out. The new analysis has incorporated new 3D microscopy techniques in the study of brands, which has allowed distinguishing brands caused by humans from others, such as those that would have caused other carnivores. “The location and frequency of cutting marks and intentional fracturing in skelet added in a press release Marginedas. The details of the work were published In an article In the magazine Scientific Reports. To the core. The study revealed other details that can give us some clues of the context in which this consumption of human flesh was produced. For example, the team points out, the bodies were prosecuted shortly after death, thus avoiding the decomposition of tissues.
