Upon sleeping mouth looks like a great idea against sleep apnea. It is not at all

The Manchester City player, Erling Haaland, captured all eyes not for that signing frustrated Madrid, but for speaking openly about a practice that, according to him, even uses when he trains: cover your mouth. And in Tiktok, thousands They recommend this trick “Because he changed his life.” We talk about Mouth Tapingthe last cry of nightly self -care. It promises a deep sleep, less snoring, better breath and even a more defined jaw. But are we facing a miraculous solution or a risky fashion disguised as well -being? The viral routine. What began as an alternative advice to improve sleep has become a viral phenomenon thanks to Morning Routines of influencers like Ashton Hall and The celebrities Morning Sheeds. In all videos they show how they use medical tape or mouth bandages with their mouths closed, ensuring that it improves their rest and health. In Tiktok, the hashtag #Mouthtax It exceeds 96,700 publications and continues to grow. However, the phenomenon has evolved faster than science that supports it. And that worries the specialists. Healthy fashion or risky practice? For some doctors, these types of trends are the perfect example of how the Internet can turn an apparently innocent idea into a health risk. So have explained in a DW reportin which Dr. Brian Rotenberg, otolaryngologist and author of an analysis published in PLOS One has explained that this trend is promoted as a magical solution, but there is no solid evidence that supports it. From Spain, Dr. Carlos O’Connor Reina, member of the Spanish Sleep Society, It coincides with statements for webconsultas: “Nasal breathing is healthier, yes, but if a person uses these tapes with a nose that does not work correctly, we are talking about a very important health problem.” There is a higher risk: sleep apnea. The main risk of Mouth Taping It is that many people use it without knowing that they suffer from sleep apnea, a potentially serious condition in which breathing is repeatedly interrupted while we sleep. Dr. Rotenberg Lor it summarizes like this: “Sealing the mouth can represent a serious risk of suffocation in people with nasal obstruction or gastric reflux.” And there are more problems. Experts cited in CNN They have pointed out that the indiscriminate use of Mouth Taping It can cause a sensation of drowning or claustrophobia, microdespertar and sleep fragmentation, worsening of the non -diagnosed apnea, risk of suffocation if there is nasal congestion, polyps or diversion of the septum, night anxiety or respiratory anguish, and skin irritation or allergic reactions. Better without tape. We know that breathing through the mouth is not ideal. Dry the throat, favors snoring and can make sleep quality. Nasal breathing, on the other hand, filters and moistens the air, protects the airways and helps to sleep better. But it is not necessary to turn to a tape in the mouth to get it. Physicians recommend safer alternatives: consult an Otorrino, review possible nasal obstructions, practice exercises to strengthen tongue and palate, sleep sideways or wear nostrils if indicated. The speech pathologist Ann Kearney, from Stanford University, has explained in CNN That the position of the tongue is also key: “If you do not correct the tongue correctly, nasal breathing is not achieved just by covering your mouth. The tongue must go forward and forward to open the airway.” A more defined jaw … One of the most popular promises that They can be observed Lately it helps “sculpt the face.” According to a GQ articlespecialists have indicated that this has no scientific basis. “There is no evidence that it strengthens or defines the jaw,” says Dr. Leah Totton in the middle. At most, adequate nasal breathing can favor lingual posture and have a minimum long -term effect, but does not modify facial features. Nasal breathing yes, but not with tape. Nasal breathing is key to health, but the Mouth Taping It is not a universal or harmless solution. Like many fashions that are born in social networks, it may seem simple, but their risks are not. If you have problems sleeping, snoring or breathing through your mouth, the answer is not on a tape, but in a medical consultation.

Testing Tiktok’s most viral anti -manners seemed like a good idea. Until I did

I am one of those people who, if there are twenty people with me and a single mosquito, will chop me. They worship me, what am I going to do? I actually try to do everything I can, because in addition to the standard itch, it makes me reaction and the bites are put ON FIRE. The Tiktok algorithm must know, because they often appear to me trick videos to prevent mosquitoes from picing you, All homemade, super simple and, according to their creators, infallible. Without too much faith, I chose the three that seemed more interesting and I prepared to try them. Everything is for science. Why mosquitoes bite us First of all a little science. The main reason why a mosquito chooses a dam to chop it is the blood group. It has been proven that people with type 0 blood have More lactic acid in the skin And this attracts mosquitoes more. But this is not the only factor, so is Carbon dioxide What do we emit. Mosquito females, which are the ones that bite, can smell the CO2 60 meters away. If our body temperature is also higher, for example by making an effort, we are the perfect target. Tiktok to the rescue During the summer, in my bag you can not miss the repellent spray, it is the only thing that works for me, but of course, it is not the most pleasant in the world because it smells very strong and leaves your skin as sticky. Over the years I have tried all kinds of things Like citronela candles, smoke spirals, repellent bracelets (luck if someone pretends not to pique a mosquito carrying one of these) and I have even planted citronela at home. Let’s see if Tiktok experts save me from this cross. Trick 1: Simple and with surprise He First trick I tried is the simplest. You just have to put half a liter of cleaning vinegar in a glass boat and add a lemon cut into slices. It smells a bit strong, but it doesn’t smell bad and it is quite decorative. I put it in the kitchen, which is where more flies and mosquitoes usually enter because the window is usually open and I waited. To my surprise, the best of all. A few days later I had my verdict in the form of three new bites. It does not seem to have a lot of the mosquitoes, but to my surprise it had an unexpected benefit: I barely saw flies. In the video they say that it is effective against flies and mosquitoes, but my perception is that, to work, it only works for the first. Nor does it look like a very durable method and after a few days it smelled. It would be necessary to renew it to maintain the effect. Trick 2: The spiritual In This video We receive a soft voice that promises that the trick will end with flies, mosquitoes, mosquitoes and cockroaches. A complete. The method consists of taking a glass bowl and putting coffee poses, half a cup of flavoring, clove and a wick of a candle. Must burn for an hour And our expert ensures that we will never see an insect again. Run, take the photo that goes out! In the explanation of the recipe I already began to lose faith because it does not even explain what that of the aromatizing is, so I had to skip that step. The truth is that I cannot say whether or not it is effective because I did not get the fuse to burn more than 1 minute in a row. I tried several wicks and nothing, when I arrived at the coffee he went out (and that was dry). From what I have read in the comments, the same thing happened to many more people. Of course, it smelled very well. Trick 3: The scientist He said that one of the reasons why mosquitoes are biting us is because of the CO2 that we emit and is precisely the basis of this trick. In the video it explains us How to build A carbon dioxide trap With water, sugar, yeast and a cut plastic bottle. The result is quite horrible from the decorative point of view, but it also smells weird. I gave him a vote of trust because it is the method that had the most scientific basis. A beautiful If I have to summarize the result in a word, it would undoubtedly fail. In the time I had the trap placed Not only did they chop me mosquitoes, it was not even one. In the comments of the video there are people who had similar results and also point something striking: at no time in the video teaches us the mosquitoes that have fallen into the trap (for whatever). I threw it three days. What does work and is endorsed by science I didn’t have much faith and my suspicions have been confirmed. None of the three methods have freed me from mosquito bites, but there are remedies that free us with a much higher success rate, mainly the Industrial repellent with Icaridin and Deet As an active substance. The DEET is the most common ingredient in the repellent spray. With a 20%concentration, it is effective in protecting us for 5 hours. The bad thing is that It has greater toxicity. He IR3535 It is a bit softer and equally effective against some mosquito species, although it would not be so much against others that transport dangerous diseases. There are also natural alternatives such as Essential oils of mint, basil or citronella that are much more respectful of the skin, the problem is that the softer, less effectiveness. Putting chemical substances on my skin is not excited, but they are the only thing that I am not going to end up bitter by itching. In addition, we must not forget that Mosquitoes are considered the deadliest animal that … Read more

The idea of ​​writing with luxury material

Even the simplest and most traditional shops are susceptible to finding a gourmet version. Bakeries, coffee shops or ice cream shops in special and exquisite mode is understood, after all we talk about food. But … And the stationery? Are the catalog of the stationery stores, economical, accessible and massive by definition, gourmetizables? There are shops who think so, and the success of stationery stores like Panda Bohéme in Vigo is a good test. Everything is gourmet. Or, at least, everything can be gourmet. It is a phenomenon that already dates from some years, linked to premiumization and specialization of traditional shops, where everyday products are transformed into objects of desire through design, quality, customization and purchase experience. It is the answer we have to the advancement of digitalization and mass standardization, looking for exclusivity, individuality and sensory pleasure in daily life and everyday life. Examples? Gourmet bakeries and pastries, Specialty coffee shops, Artisanal ice cream shopscheese and selected charcations, design florists and, of course, and linked to gourmet stationery stores, independent libraries. And stationery. This, applied to the stationery stores, runs in the same direction: the type of products that are in a traditional trade in the sector, but with the focus on the exclusive, the artisanal and creative inspiration. A lot of material for crafts, calligraphy, drawing and accent in the premium product: notebooks, pens, folders, all of good quality and with somewhat higher prices than usual. And also import products, especially Japan, where there is a whole Cultural obsession with stationery products. German origins. A pioneer example in Europe from this type of shops is Divine Designfounded on Germany in 2003and that from its origin it was distinguished by its commitment, unheard of in the times prior to the global massification of the Internet, for ecological materials and the high standards of quality of its products. As of the 2010, The phenomenon began to expand through Europe and Asiadriven by the rise of Japanese, Korean and American brands. The return to the world in a thousand stationery. According to the trend he has expanded around the world, each country has welcomed it to its aesthetic and cultural preferences. For example, in Japan there are Material brands for this type of shops like Kokuyo, Tombow, Zebra, Pilot, Uni-Ball, Sun-Star or Midori, and stand out for how they combine functionality, aesthetics and pleasure of use. The deep roots of Japanese culture with the paper industry is remarkable, both for its millenary tradition with material and his conception of writing and calligraphy as an act of emotional root, as with the adoption of recent aesthetic currents, such as The Kawaii. In Korea, aesthetics is even more accentuated, with brands such as Iconic, Monami or Livework, with the accent placed on the design and soft colors. On the other hand in the United States, it is committed to the functional and the resistant, although there are also minimalist designs and veteran brands, where names such as Cloth & Paper or Smythson stand out. And in Spain? The phenomenon has been settling in Spain for a few years, with certain common elements: the essential presence of Japanese and Korean material and the importance of social networks and the Internet in the business. For example, one of the most prominent gourmet stationery stores is Panda Bohèmeof Vigo, with a physical store of more than 250 m² where it organizes events and workshops, such as Pop-ups of import marks. Significantly, your Instagram account has almost 40,000 followers due to the care with which they show and teach their catalog. Other important stores are Likely.es, Bomagui either Ikigai. Paper philosophy. This flowering of libraries has a lot to do with the movements of Digital detoxification who advocate a Return to physical experiences. The pleasure of writing on paper, although it seems unchanging in these times of total digitalization, has some connection with ancestral traditions that in high -end stationery stores have been in charge of modernizing and providing meaning again. New times for activities as old as humanity itself.

The last idea to include tolls on the highways of Spain

From Madrid to Barcelona for about 18 euros. From Bilbao to Cádiz for more than 30 euros. That is The proposal of the Association of Construction and Infrastructure Concessionaires (Seopan) and in that money there has been none of the tolls that we can find along the way and that, without a doubt, would make the journey more expensive. And it is that the employer of the road construction companies has had an idea to finance the thousands of kilometers of highways that are still free in our country. And, from their point of view, they have it very clear: that The drivers pay 3 cents/km route. The figure is much higher for heavy transport for which they propose a rate of 0.14 cents/km route. That is, multiply almost for five previous figures until we place us at almost 90 euros in Madrid-Barcelona and almost 150 euros for crossing Spain in truck. An old dream with Europe looking The proposal was presented by Julián Núñez, president of the association that covers giants such as ACS, Ferrovial, Action, Abertis, Ohla or Sacyr, among others. It indicates that the country has to invest 11,494 million euros for the conservation and maintenance of roads that have not been carried out in recent years. That game is part of the 38,447 million euros in 25 years that, according to their calculations, they are necessary to keep the roads in optimal conditions until 2050. In those items maintenance works are contemplated but also the construction of Roads 2+1 to “improve road safety” or the deployment of load infrastructure for the electric car. All this, they say, would generate income in 25 years of 143,024 million euros, a fiscal return of 35,314 million euros and a public spending saving of 41,038 million euros. Money that would be used to invest in the maintenance of the roads themselves. The implementation of payment for use is one of the great dreams of the construction companies since this would allow them to offer down construction and maintenance services, facilitating these actions and, of course, facilitating their business. However, they ensure that Spain accumulates 68% of free highways throughout Europe which total 13,674 kilometers free of tolls. A flag that the government has presumed, putting each liberalization in value while balancing with Europe. Last year, in fact, Transport Minister Oscar Puente assured that “the roads are not free, or are paid with taxes or tolls.” He did it in a forum organized by The Spanish And the words of Puente soon were read as a notice to navigators. However, just A few hours later he would defend that this was not a way to “reopen the debate” and stressed that the government had released 1,000 kilometers since 2018 on toll highways. To that measure, it has joined not imposing more tolls on roads such as AP-9, AP-66 and AP-68 where bonuses are applied. These decisions, however, collide frontally with the interest that Europe has reiterated in imposing tolls on Spanish roads. For years, institutions have put the table on the table obligation to impose a tarification For use to roads in exchange for continuing to water our country of European funds. This led the government to include it in its Recovery and Resilience Planalready presented in 2021. Since then, The equilibrium game That the Spanish Executive has maintained has made the roads remain free but a new threat has also arrived from Europe: a possible complaint if we do not correct the way. And, although the supposed payment for use comes from afar, the runrún on the payment on the roads has been increasing. Especially if we consider that in 2021 there was already talk of imposing A toll system in less than three years or that Pere Navarro, director of the DGT, has already suggested Who could and who not pay those possible tolls. What they defend from Seopan in their proposal is that, however, Spain would continue to pay cheaper tolls than the rest of Europe since, they say, the average is 0.09 euros/km route for cars and 0.018 euros/kN route for heavy transport. In The countryThey emphasize that Spain represents 21% of all kilometers of high capacity of the European Union but that, however, only 13% are payment. That is, we are an exception that Seopan seeks to reverse with a porch system To pay for use, taking advantage of the fact that the money that the State must due to the investment of the roads already exceeds 10,000 million euros. But also Europe, what For years he presses so that Spain once and for all a melon from which, in the government, He doesn’t want to take care. Remember that it is something that You have been talking since 2012. Photo | Erwin Brevis In Xataka | Hunting for “Simpa” in the tolls of Europe: the new EU system to collect fines abroad

Ukraine has borrowed the most basic idea of ​​Lego. And has transformed it into the final machine for war

Drones with shotguns of double cannonrobots Lanzaluelaunmanned vessels With missilesairplanes With shotgunsdevices with kilometer cables of optical fiber Looking for its goal through algorithms … The war in Ukraine became the largest war laboratory of modern contests, but in recent months that transformation has become more palpable than ever. Because soldiers are no longer recruited, they are recruited directly robots. Modular fights. They counted this week In Insider that among the key actors of this unprecedented experimentation of military terrestrial robotics is the company Estonia Milrem Roboticswhose land autonomous vehicle Themis It has been deployed by the Ukrainian forces on the front. The striking, however, is not only the presence of these systems, but the way in which Ukrainian soldiers are using them: unforeseen and highly creative. Kuldar Väärsi, founder of the company, He has highlighted that troops have managed to expand their abilities by adding modifications, adaptations and even using them to Not expected taskssuch as collection of corpses, controlled explosions, supply transport or mines. In a context where each resource can mean life or death, tactical innovation is born directly from the front. Military Lego. The Thanmis model can load up to 1,200 kgmove at 20 km/Hy wearing weapons like machine guns or launcherin addition to acting in evacuation, transport or deactivation tasks. However, its real value lies in its modularity: it is an adaptable system, almost like a set of War Legoaccording to Oleksandr Yabncanka, head of robotized systems of the Da Vini Wolves battalion. Without having specialized models for each mission, the Ukrainian units use a single type of robot as a common basis They modify according to your operational needs. This flexibility reflects a generalized philosophy in the Ukrainian army since the beginning of the conflict: improvise, adapt, survive. Fifth Generation Themis Military reinvention. Since the first year of war, Ukraine has been synonymous with reuse and Technical creativity. He has re -adapted Western lanzamisiles to Soviet platforms, mounted machine guns old in trucks, modified drones Commercial for suicidal missions and created mills such as unmanned ships and turrets with artificial intelligence. Milrem is not the only company at stake: local companies such as Roboneers either FRDMtogether with European signatures such as ARX ​​Robotics (Germany) or Isolit-Bavo (Czech), are actively collaborating in the design and deployment of new models of land robots. This confluence between foreign industry, local operators and tactical demands generates an eInnovation sew that had not been seen before on this scale. The war of the future. Be that as it may, there is a name that has risen above the other models. Bloomberg explained it With a scene: on the wooded banks of the Dnieper River, on the outskirts of kyiv, two small robotic vehicles descend towards the sand as if they were mechanized crabs. One transports food, the other sowing anti -tank mines. It is about Termit modelTangible symbol of how Ukraine, after three and a half years of total war against Russia, has become the forge of a new war paradigm: a war based on modular technology, cheap and fast to produce. In a context of scarcity, urgency and systematic improvisation, the country has managed to create an arms ecosystem that rivals (for its agility and efficiency) with the great industrial powers. Already the 40% of the armament which uses comes from National Sourcesand according to Zelenski, this autonomy can serve as model for allies of NATO that face an increasingly volatile and dangerous geopolitical future. Military production, as he says Oleksandr Kamyshin experthas become the oil of Ukraine, the resource on which its survival is constructed. Ukrainian Termit Models Robot and converted engineers. The case dE Maksym Vasylchenko embodies the metamorphosis of the country. In 2022 he worked by installing food machinery for international companies; today directs Tencorea startup that has developed The Termitthose modular robots that already use more than twenty military units in the front. With satellite connectivity Via Starlink and load transport capacity, evacuation of wounded or deployment of mines, these vehicles They have replaced to soldiers in areas of maximum risk, not only because they are more expendable, but for its lower cost: a basic termit It costs $ 20,000while the death of a soldier supposes the State a nearby total compensation at 380,000. A different company. Of five initial employees to early 2024Tencore has grown to 175 workers, six venues, and projections of 80 million dollars In annual income. All driven by direct collaboration with combatants: a chat with forty active users serves as a constant feedback channel, where every five or ten minutes suggestions are provided. This agility, impossible in the processes of acquiring Western governments, is one of the keys to the success of the Ukrainian model. An army of termit ready for operations An area of ​​death. We have coming counting: The war in Ukraine has established a new operational environment dominated by low cost drones. Approximately the 70% of the Russian team destroyed has fallen by unmanned vehicles, many of them converted commercial adaptations. These FPV units already operate in almost any climatic condition, deliver blood in trenches or attack tanks with surgical precision. The battlefield has become constant, immediate and three -dimensional, expanding the call Kill Zone At any time and place. At the beginning of June, Ukraine demonstrated its offensive capacity coordinated to the destroy bombers strategic in Russian bases that went from the north of the country to Siberia. The traditional logic of the front has been replaced by a decentralized war where the direct human risk is reduced to the minimum possible thanks to autonomous, fast and sacrifiable platforms. The Russian answer. Of course, Moscow has not lagged behind. As We have spoken For weeks, ha adapted the drones Iranian Shahed to your needs and has begun to display vehicles Fiber cable guided optics, which makes them immune to electronic interference. In May, the Russian production of combat drones increased 17% In a single month. The Russian strategy is clear: standardization, volume and industrial … Read more

As the Puerta del Sol is a tree desert, Madrid has had an idea for this summer: putting awnings

With the thermometer Nailing with the 40ºC of maximum and a sun of rigor, if there is something sued today in the streets of Madrid is shadow, a shelter in which to enjoy a refreshing truce before continuing on their way to the office, house or the institute. To create one of those ‘Climate shelters’ In the urban heart, a few weeks ago the City Council He started installing Toldos in the middle of the Puerta del Sol, 32 panels with which he wants the square to stop being a pan. The problem is that its installation has unleashed a considerable stirboth for the solution itself and its cost. Shadow, where is there a shadow? The Puerta del Sol is an emblematic, sculptural place, forced to Thousands of tourists Every year and central node of Madrid. The problem is that something key is missing, especially in summer: shadow. Your around 12,000 m2 They are a wasteland in which it is difficult to protect themselves from the sun, a problem when the city faces a heat wave like the one in these days. There are those pulling irony It refers to the square as ‘La Sartén del Sol’. Why is there no shadow? Because it was never considered necessary. The City Council argues that in its 163 years of history the square never had “elements of shadow”, although there are who holds that in his day he had some trees and more than a century ago he already incorporated awnings. Historical debates apart, the Consistory assures that today the configuration of the Plaza conditions what can be done or not in it: below, scarce 20 cm of the pavementrests a slab that separates the square from one of the largest subway stations in the city, in addition to galleries. And why is it important? Simple. Because what is done in the square should take into account the huge structure that opens below. Martínez-Almeida team remember That a few years ago it was studied to plant trees in the only area of ​​the square that does not have infrastructure under the pavement, but the Municipal Historical Heritage Commission ended up lying the initiative. The reason? The vegetation perhaps threw some shadow and refresh the environment, but the idea did not respond to historical or urban criteria. He simply proposed to plant trees where he could, without contributing more reasons. What if we put awnings? In the absence of trees, good are Quita and Pon, a solution that is already used in the street of other Spanish cities punished by the sun, such as The center of Seville either Malaga. That is the idea that the City Council was raised, which launched its administrative machinery to project, hire and install a system of panels that cover part of the square. They wait, but the fabrics began to settle Two weeks ago. The awnings, 32 in total, are manufactured with Microperforated PVC ivory and have been arranged in such a way that they offer shade to pedestrians that walk from Alcalá to Arenal. To hold them, anchors were installed on the facades, tensioners and stainless steel masts in some granite banks. The idea is to use a threaded tubes system to place and remove panels throughout the year, as is done in other cities in the south. Why is there debate? For several reasons. Input by the solution itself and its effectiveness. “They are not a simple ornament or a whim: they are a late and expensive response to an urban policy of the PP, which for years turned our public spaces into authentic cement plates,” criticism in The country Pedro Barrero, socialist spokesman in the Commission of Works and Equipment. To that debate contributes that the square was reformed Just a few years ago With one millionaire investment without those guaranteed works shadows in the environment. Another background debate is whether the square may or may not host trees, beyond the handicap that the subway station is underneath, or if there are better alternatives to the awnings. The City Council insists in which the configuration of Puerta del Sol dates back to the nineteenth century and this will be “the first time you have shadows in its 163 years of history.” The proposal also received the approval of the Historical Heritage Commission. The big question is … Is it used for the 12,000 m2 of the square a solution that has demonstrated useful for narrow streets? Are there more factors? Yes. The price. The installation of the awnings will require considerable investment, around 1.5 million of euros that add to the cost of the reform of a few years ago. In networks there are who questions That a million and a half are reversed to a work that, in the end, will mean the installation of about thirty PVC awnings. From the City Council they clarify that to carry out the project they have had to carry out studies and undertake works that are not appreciated with the naked eye, such as adapting the banks, emptying them and providing them with steel plates to ballast the anchor of the masts. The goal? Ensure that the canvases endure wind gusts without the foundation affecting the structures located under the square.

In World War II, the British were looking for an antibunker bomb. So they copied a Disney idea

The morning of last Sunday, June 22, The United States deployed its B-2 With a mission: launch, for the first time, its new MOP pumps on Iranian bases. These mass bombs have a single function: eX PLACE IN Underground Bases And, despite being avant -garde armamentits technology began to be tested decades ago, in the Second World War. It was the British who developed a bomb capable of bursting a bunker, and their inspiration came from the most unexpected place. A Disney movie. Need. It is in the war when the brightest minds of each country gather to invent new ways of killing. Even if they don’t know what the consequences of their creations will be. The World War I It was a period of Technological Revolutionthe second more of the same and In the Cold War The Explosion of nuclear bombs (and almost that of chickens). In short: each country in conflict wants have the “fattest” bomb. In the mid -2GM, the British sought a powerful bomb, but with a more concrete objective than that of causing all possible damage: they wanted something capable of advising a blow to the bunkers heart and Nazi submarine factories. Thus, they developed the Tallboy and the Grand Slampumps of five and ten tons respectively designed to hit near the target, penetrate the earth, exploit and cause damage to the shock waves transmitted through the ground. The idea was good, but they still needed something more concrete than those “earthquake” bombs. And then, someone saw this propaganda movie of Disney: Drawing pump. Leaving aside that you could keep your mouth open because … yes, that Disney produced ithe who saw the short was Edward Terrellof the Royal Reserve of Naval Volunteers. It is said that, after watching the film, Terrell and other officers, they would ask if it would be possible to design a bomb that directly crossed the concrete and destroy objectives such as the Nazi submarinesas seen in one of the frames, instead of waiting for the expansive wave of an earthquake to damage the underground base. In September 1943, engineers got to work while the viability of the pump was discussed. There were those who opposed, but Churchill was approved and, there, the development began. Edward Terrell and two other RAF officers with a Disney bomb Promising. The Disney pump, baptized Officially as “4,500 pump assisted by rocket to drill concrete” (‘Disney bomb’ has much more stuck, where we are going to stop) it was massive not so much because of the dimensions, but because of the weight and its explosive capacity. With just over five meters long and 43 centimeters in diameter, it had a weight of 2,000 kilos. As his name indicated, he was driven by RP-3 rockets And as an explosive it was loaded with 230 kilos of ‘Shellite‘, a mixture designed during World War I. Thrown from Boeing B-17 or B-29 aircraft, its operation was simple: to boost with the rockets to reach a speed of more than 1,500 km/h, penetrate everything possible due to accumulated kinetic energy and detonate late within the installation. In addition, its maximum penetration was about 5 meters of reinforced concrete, enough to cause great damage to enemy structures. Afternoon, too late. The bomb was promising, but it took too long. They began to develop late (when they had the idea, go) and that caused that it was not ready until almost the end of the conflict. In January 1945 they carried out some tests and, although the bomb was British, it was the United States Air Force that had of it. Between February and April 1945 they launched a total of 158 Disney bombs against bunkers and submarine factories in Germany. A clear objective was Valentin, a U-Bats factory That it was about to be completed, something that the allies could not allow and managed to cause damage to the target with armor 4.5 meters thick, but had a trick: it had already been previously damaged by the Grand Slam bombs of the British. A fair shotgun. The Disney bomb was a disaster for two reasons. The first and most obvious is that it came very late and attacks on underwater bases did not mean a real difference in the outcome of the conflict in the European territory. But, in addition, they failed. During the Valentin bunker attack More than 60 pumps were launched, but only one directly impacted and, as we say, the damages caused were preceded by the explosions of the British bombs thrown days before. For more inri, in evidence during the years after World War II with controlled releases in the Helgoland Islandof 76 bombs released, it was discovered that the lighting of the rockets failed in 37% of the cases, very limiting the penetrating power of the projectile. In addition, some bombs exploited prematurely and would not serve to achieve the objectives. Yes one thing was discovered: the maximum penetration of 5.08 meters in concrete. The MOP, Disney’s legacy. In the end, between technical, tactical and temporary problems, the efficacy of the Disney pump was extremely limited, but it is clear that it represented an important technological advance in the Antibunker war. So much that he laid the foundations for future penetration weapons. And of those rains, these sludge, as they say. The GBU-57A/B. launched by the US against Iran is the latest technology of the MOP bombs, or ‘Massive Ordnance Penetrator’. The big difference with the Disney pump is that this huge 6.25 meters long projectile and the FRIOLERA OF 13,600 KILOS (2,400 of them are explosives) Yes it works, also penetrating up to 60 meters of concrete. And another difference is that it is launched from such high (12 kilometers from a B-2) that does not need engine, since it is gaining speed as it falls, being very precise thanks to its laser guidance. In short, technology that is not so much of science fiction and that shows that we are great … Read more

With the electric consumption triggered by the air conditioning, Singapore has had an idea: buildings that “sweat”

Fresh news: it’s hot. A lotand it doesn’t look like This summer is going to give us a break. Bet on Fans or by him air-conditioning It is a solution, but there is a problem: temperatures will continue to increase and Electricity consumed by air conditioning devices It is a problem. Urgently Find passive solutionsand Singapore may have found the key thanks to a new painting. Your secret? Makes buildings “sweat.” Short. In 2022, air conditioning represented 7% of world electricity consumption. The estimate It is that, by 2050, that electrical consumption triggers up to 20%. In order to cool buildings, there are already researchers who are experiencing with heat dissipation solutions to create fresher environments without the need for air conditioning, such as The nanomaterials or a Botijo ​​technology nut rotation. Although we are seeing how to make the air conditioners are more efficient. But there is an easier solution that could be applied to already built buildings: a layer of paint. The Insulating paint It already exists, with examples Like the ultrabrabas developed by the University of Purdue that reflects Up to 98% of the light to maintain surfaces up to 7ºC fresher than other solutions, even under direct sunlight. Now, in Singapore they have developed a painting that mimics the sweating for which we regulate our temperature. Buildings that “sweat”. As we read in Sciencenewsa group of researchers from the Technological University of Nanyang is the responsible of a painting baptized as CCP-30 and what has special is not a color, but its operation. It is developed based on cement and combines three cooling strategies: radiative, reflection and evaporative (the latter, the one that uses our skin). And it works like an organism that sweats. The porous structure of the paint can retain up to 30% of its weight in water, which slowly releases the environment. It’s like the function of air conditioning dehumidificationbut passively. By absorbing water and dissipating heat, the released steam is cooler, contributing to cool the environment. SUV. If the sensation can be similar to that produced with ultrabrabic paint, why invest resources in replicating something that already exists? The main reason is that this ultra -ABANCA painting that reflects heat does not work at all well in Wet environmentssuch as Singapore itself, but also in Thailand and other areas where the moisture percentage is important. This reflected light is trapped by water vapor in the environment, and in large cities the creation of heat spotlights is encouraged. Come on, which contributes to embarrassment. The new porous painting, when not working by reflecting light and heat, does not have this problem and allows the buildings to be correctly isolated, fulfilling that passive cooling function. Promising. To hold their arguments, the researchers painted three houses with different types of paintings. One with a common white paint, another with a commercial painting that only uses radiative cooling and another with its new “sweat” painting. After two years exposed to the sun, rain and humidity of Singapore, while the first two became yellowish, the new formula continued with its white color. That is important not so much for aesthetics, but to continue being efficient reflecting the light. In addition, being prepared to absorb moisture, it does not crack, being another advantage. On the other hand, the house painted with CCP-30 reflected between 88% and 92% of sunlight even when it was wet, and emitted 95% of the heat it absorbed. Tandem with air conditioning. CCP-30 is designed to cover the outside of buildings, not homes or interior areas, acting as a first shield to combat heat. According to the area, the use of air-conditioning It will continue to be necessary to endure high temperatures, but researchers claim that a house covered with its new painting meant between 30% and 40% less use of air conditioning. It does not stop turning the building into a botijo. In the end, as we said, the use of paintings against heat is nothing new, but renewed formulas can help not only to refresh interiors, but to eliminate those urban heat spotlights in cities with a high percentage of moisture, calls “Heat islands”And the good thing about being a painting and not something that require a new construction It can be applied to existing structures without complex reform. I only ask that this type of painting arrives soon, but it is nice to know that passive ways of refrigerating households are being investigated, such as the Cement developed by the Public University of Navarra.

The Rocambolesque Idea that is feeding a fish farm in a town in France

The first men who traveled to the moon during the Apollo missions subsist based on lyophilized food and sweet or salty jelly -coated cubes. The thing has not gone to better over the years. But if the French succeed, astronauts from lunar missions can eat fresh fish. Lubinas raised on the moon. That is the goal of Lunar Hatcha rocambolesco scientific project that is already underway in a fish farm by Palavas-Le-Flots, south of France. The fish that raise in this small center are not any lubins, but the founding generation of the futures “Aquanautas” lunares. Its offspring will travel to space in the form of fertilized eggs in order to establish the first extraterrestrial fish farm. High quality protein. If we are going to establish a permanent base on the moon, what less than to give us the taste of dinner a fresh lubina. The brain behind this project is Cyrille Przybyla, a researcher at the French National Institute for Oceanic Research. “Fish is an excellent source of protein, because it is the animal body that we best digest and contains omega 3 and vitamins B important that astronauts will need to maintain their muscle mass,” Przybyla said to The Guardian. The question, which he poses, is not whether we need it, but “how we can produce these foods at so much distance.” Lunar Hatch. The experiment, financed by the European Space Agency (ESA) and the National Space Studies Center of France (CNES), will send the eggs to the space calculating the time it takes to hatch upon reaching its destination. Although an assigned space flight does not yet have, the idea is to perform the first tests at the International Space Station, assisted by European astronauts in orbit. After observing their development, the eggs would be frozen and returned to the earth for an exhaustive analysis. If the tests are successful, the next step would be to climb the system for a future implementation on the Moon. Not the first fish, yes the first fish. We have already seen fish in space. The first were small Mummichogs in an Apollo mission in 1973. More recently, Cebra fish have helped study muscle atrophy. But this is the first time that the objective is purely gastronomic: create a source of regular and renewable food for astronauts and crew of future lunar and Martian bases. The first space fish. This is not (alone) of nutrition. The true mill of Lunar Hatch is to create a completely closed and self -sufficient ecosystem, without waste, exempt from continuously replenishing food with load flights from Earth to end eating crickets. Everything is recycled within a fish farming system that should be autonomous for at least four or five months. Of course, many “Aquanautas” will be needed. Scientists have calculated that to provide two weekly fish to seven astronauts, about 200 lubins would be needed. Image | Lfremer In Xataka | We have been growing lettuce in space for years.

The heat arrives and you want to drink cold water. Science has a much more effective idea: drink hot water

Summer arrives and with it staying well hydrated becomes an imperative. The heat will surely make a glass of cold water even more appealing, but it is likely that we have ever heard that the water, better hot. Is it a myth or is there a reason behind? Drink water. Drinking water is the important, hot or cold, keeping our body hydrated is the main objective. Despite this, drinking hot water or cold water is not exactly the same: our body can react differently Before the stimulus. This is what science tells us about it. Better digestion. Hot infusions are a desktop classic. Coffee, tea or chamomile are usual choices to close the food, especially if it has been copious. When consuming these drinks we are, indeed, Drinking hot water. In doing so we are moisturizing our body and allowing water to help the flow of food in our digestive system. Part of the effect we owe it to the mere fact of being drinking water, but there are some studies that suggest that the temperature could play an important role in the digestive effect of this desktop habit. A Study published in 2016 Focused on newly operated patients, he observed that the consumption of hot water in recently operated in the colon had a “positive impact” on subsequent intestinal movements. Do you lose weight drinking water? In 2023, a group of researchers conducted An experiment in which a group of participants had to consume a certain amount of warm or hot water after meals, while the rest had to consume the same amount of water at a temperature without specifying the temperature. As reported by the team, the group that consumed hot water lost body mass more speed than the control group. This could explain why we associate drinks such as tea are associated with weight loss. The diuretic potential of some infusions and the benefits that others have on intestinal transit could be related to the mere act of drinking hot water, but the truth is that the tests we have are very limited, so we still cannot add the hot water to the eternal list of candidates for “miracle diet”. Cool ourselves with hot water. It may seem Little appealingbut hot infusions are a classic in some of the most scorching environments in the world. Our body is about 37º Celsius: if we consume something at a higher temperature, our body will absorb that heat. It doesn’t seem like a good plan. And yet it works (although not always). The key, The experts point outis how our body dissipates heat through sweat. A hot drink can activate nervous receptors by sending the signal that the temperature is greater than what is actually, which in turn does that our body begins to sweat and thus begin to dissipate heat through the water we expel by the skin. To sweat, of course, it should also be hydrated. When may not work? Drinking hot water to reduce our body heat can be a bad idea in some contexts, mainly When moisture is high. Moisture makes sweat dissipated, with it, avoiding it heat. Temperature and hydration. Hot or cold, we began by saying that the most important property of water is that it hydrates: our body needs this liquid to stay alive and drinks are the main source to obtain it. Now, we know that Not all drinks hydrate the sameDoes the water do it indistinctly of its temperature? Maybe not. A Study published in 2013 He calculated how the water temperature affected the rehydration process. A too hot water could induce sweat, causing us to lose some water at the same time we rehydrate. By contrast, water too cold or too hot can also make us drink less. The team observed that a better rehydration was achieved when consuming fresh water, about 16º, a temperature similar to that offered by tap water.
