The strangest phenomenon of every summer is also an industry of 500 million euros: the “Mermaiding”

The fever for ‘La Sernita’ that you lived in your childhood is nothing compared to the movement known as Mermaiding: a swimming style inspired by sirens and tritones and that is already trend, and it could almost be said that Lifestyle. Conventions, courses, exhibitions … There are people who live very happy without the lower extremities to replace them with a fish tail, even temporarily. And they have very convincing reasons. To move the tail. He Mermaiding It consists of swimming using a siren or triton tail, usually manufactured in silicone or synthetic fibers (and that can cost $ 5,000 in the most sophisticated cases), simulating the undulating movements characteristic of these creatures. It can be done in swimming pools or open waters, and its practice combines Swimming, apnea and some synchronized. In the last decade, the Mermaiding It has become In official sports Since 2019 in countries such as China and the United States, but we talk about it every summer for its quirky visual characteristics, which obviously include a fish tail. Mermaiding: A typology. There is Many variants and forms of practicing diminishing. Perhaps the most popular is the one oriented to the entertainment of profane in Sirenism. It provides the possibility of swimming experience with a siren or triton tail, and there are academies that are responsible for organizing Events to learn to do it. On the other side of the spectrum is the Mermaiding Deportivo: To officially practice it, specific courses are required with certifications such as SSI Mermaid either Padi Mermaidin which techniques such as the kick of dolphin, undulation and aquatic coordination are perfected. In a middle ground between them there is a variant of Mermaiding For shows, aquatic and thematic parks, hotels, as well as participations in spots, video clips and varied performances. It’s a use of Mermaiding More artistic and not oriented to competition. Mermaiding No: Sirenism. In Spain, mass conventions of sirens such as the Mermagic with that takes place every year in the United States, but for example, the Sirenas Mediterranean Academy It has been standing since 2014, giving courses and organizing private parties with sirens included. And there are organizations like Sirénida, a Professional Sirens and Triton Catalog Contractable for shows of all kinds. At the moment it is becoming, cursillo and of Cuqui Experiencein a more leisure option. Professional sirens. The Netflix documentary of 2023 ‘Sirena people’ details what the day -to -day life of these Sirenism professionals is. Because yes, it is not a handful of eccentric with silicone tail: in the United States it is a business with abundant ramifications in the entertainment world, with interventions in aquariums, musicals underwater and a long etcetera. The documentary shows parts of the job of mermaid as little glamorous as castings to work as a siren in a show, and you can see that it is completely legalized and normalized. According to the program, the Sireno world already moves 500 million dollars in the United States. Not so secret origins. From professional mermaid associations They certify that they have experienced an explosion of interest and an increase in applications in recent times, which link to the premiere of the Netflix documentary series. In it you can see those who were sirens in the park of Sirens Weeki Wachee, a theme park created by a royal sailor, Newton Perry, in 1947. In it there was a tiny scenario and a spring where the sirens made a show: the venerable precedents of the current sirens in aquariums and thematic shows. Illustrious predecessors for a business that comes out again. Header | Photo of Michael Hystead in Unspash In Xataka | 24 board games and agile and fun hobbies to play in summer anywhere

North Korea is transforming its army into the Ukraine War. And the strangest thing is the response of South Korea

Russia and North Korea confirmed In April an open secret: that Pyongyang It is cooperating With Moscow in the War of Ukraine at various levelsincluding from troops to military arsenal. In return, Russia is giving North Korea what longs for: a functional army and a military capacity that could represent a challenge to global strategic balance. Thus, the strangest thing is the position of South Korea. Seoul’s silence. I remembered this week The Guardian. Although South Korea reacted rapidly to condemn the launch of ballistic missiles by North Korea in May, his government kept absolute silence when a KN-23 missile North Korean (designed precisely to attack South Korean objectives) hit a residential building in kyiv, Killing 12 civilians. That omission was not an isolated case: there was no answer when Russia displayed An anti -aircraft system To protect Pyongyang, or when it was learned that Russian instructors They were training to North Korean drones operators in their own territory. All this points, According to analyststo a disturbing lack of understanding by Seoul about the scope of the military transformation that is experiencing North Korea, a fed transformation not (alone) into theoretical exercises, but in the real crucible of war in Ukraine. A metamorphosis. According to Ukrainian military intelligence, North Korea supplies 40% of ammunition that Russia uses in its offensive against Ukraine. In parallel, Pyongyang has accelerated its own arms production and has sent an initial contingent of 12,000 soldiers to the Russian region of Kursk, a figure that has grown with another 6,000 troopsmilitary engineers, bridge experts and railways, logistics staff, military police, electricians and even interpreters. Although officially these soldiers unfold in reconstruction tasks, the real gain for Kim Jong-un lies in what their troops They are learning: Modern War, Coordination of Combined Weapons, Management of Recognition and Attack Drones, Electronic War and Technological Systems unknown so far for its Army. And more. Moscow’s support has also been translated into Technology Transfersincluding improvements in the precision of KN-23 ballistic missilesalready used against urban centers such as Járkov. According to Ukrainian intelligence, North Korean soldiers captured They revealed such an extreme ideologization that they tried to commit suicide biting their own veins to avoid being interrogated. One of them proudly said would return to your country as a hero for having fought in a modern war. Political calculation It is the other leg that slides. While Zelenski warns directly To South Korea that the time to act is now, before thousands of North Korean missiles and improved drones begin to threaten Seoul or Tokyo, the South Korean authorities seem look. The posture, According to expert Yang Ukresponds to a delicate balance Between strategy, internal policy and economic considerations. The reason? Openly recognize the danger of North Korean rearmament and his experience in combat would imply have to answer With firm measures (including perhaps sending weapons to Ukraine), something deeply unpopular among the South Korean population. In addition, Lee Jae Myung’s government is committed to a pragmatic foreign policy focused on economic recovery, in a context where Russia was one of its main commercial partners before war. On the political level, the South Korean ideological division revolves around the position against the north: while the right insists on the rearme and the hardening of the defense, the left Defend the dialogue And he maintains that South Korea has no obligation with Ukraine. The recent political crisis derived from the attempt of declare martial law He has left many officials reluctant to expose themselves publicly or make decisions that may be subject to political attacks. Between ambiguity and paralysis. If you want, Seoul’s hermeticism can be understood as an extension of its traditional “strategic ambiguity”, an unwritten doctrine of not getting involved in international conflicts that may put their own relations with key actors such as China or Russia at risk. However, some analysts warn that this position is staying dangerously outdated Faced with threats that evolve in months while military bureaucracy continues to work with planning times that require years. Godzilla level. He told the Guardian The retired general Chun In-bum that South Korea faces a threat comparable to a “level 10, super Godzilla”, but his institutional apparatus still acts as if only saw a tiger. In his opinion, the South Korean military doctrine remains anchored in a paradigm prior to the era of drones and is not adapted to face an adversary that is assimilating, In real timethe lessons of the most brutal conflict of the 21st century. From its point of view, the country is in front of a train that approaches at full speed, and is still in time to move or prepare, but not for much more. Reconfigured future. In short, the Military cooperation Public between Russia and North Korea is already leaving a mark on the Asian power structure. Moscow is integrating Pyongyang into its logistics chain and long -term supplies, in an alliance that could alter regional military balance even after the war ends in Ukraine. Meanwhile, South Korea seems willing to Keep observing From the barrier, trapped between fear of conflict, economic calculation and a political class immobilized by polarization. The problem is that northern neighbors seem to be gaining experience, technology and internal prestige to full machine for his role in a real war. And in that scenario, the question no longer points to whether that experience will turn against Seoul, but rather when.

The bone of the sardines is an important source of calcium. And it is not the strangest food that this mineral gives us

Calcium is a fundamental element for our body and, especially. Surely we have heard throughout our life (and especially in our childhood) that you have to drink milk to gain calcium For our bones. While milk is far from being the only food capable of nurturing our bones with this mineral. First of all, perhaps it is convenient to explain why we need calcium, because the notion that calcium is good for our bones, although exact, does not give us excessive information either. Fundamental for the formation and maintenance of bones and teeth, calcium is the most abundant mineral in the human body and 99% This is precisely in our bone structure. That is why His lack It can cause problems such as rickets in children and osteoporosis in adults. But calcium also exercises as electrolytea mineral with electric charge that our body uses for various functions. In it Case of calcium Specifically, its presence in muscle cells allows us contract and relax our muscles and transmit signals through the nervous system, in addition to helping blood and hormones circulate through our body. It is difficult to talk about calcium without starting with dairy. These are the foods that we most associate with the element. Milk contains abundant calcium and some of its derivatives contain even more. In a natural yogurt, low in fat (about 125 grams) we can find Approximately 248 milligrams of calcium. Some cheeses contain calcium concentrations that are even superior. However, there are foods that can contribute both calcium and dairy products. Or even more. Some calcium sources can be surprising. We can find abundant calcium in vegetables such as the Brocoli, Kale or Collized, or in the Berza or cabbage. But perhaps the most surprising plant source is another sheet: that of the ortiga. Cooked, this urticating plant can contribute us Around 125 milligrams of calcium per 100 grams of product. Diverse sources Another important calcium source is in fish. We know that calcium in our body is concentrated in the bones, but the bones of other animals also have calcium. Normally we do not consume food with bone, but there are exceptions. For example, the thorns of The sardines. This makes this fish, consumed with bone as we usually do for example when we eat it, be it Another unique calcium source. The drinks that we usually use as an alternative to milk are, curiously, a source of calcium in themselves. The reason is that these are usually made from calcium -rich foods. Soybean is one of them (and therefore also other derivatives such as tofu), but also some nuts such as almonds. Some of these drinks can also be enriched with calcium to strengthen this contribution. In general, we can also find various foods enriched with calcium, including dairy, juices, and flours and their derivatives. We can even find Calcium supplements If we require them. The calcium content of a food is not the only thing that should matter. The reason is that our body does not always absorb all calcium present in these. In the absorption of this mineral, another nutrient plays a fundamental role, the Vitamin d. This micronutrient plays a key role in the absorption of calcium and also phosphorus.

Hundreds of years ago, no one saw a beaver in the Tagus. That has just changed and is not even the strangest of all

The saddest thing that can be said of an animal can be said of the Iberian Castor: No one is very clear when it was extinguished. For years the researchers have discussed whether the last specimens disappeared in the seventeenth century, in the eighteenth or, even, in the nineteenth century to realize that all this was wet paper. But the only available evidence They place them in the second century BC. After that moment, nobody knows what happened to them. But something happened in 2003. In the spring of 2003 and illegally, someone introduced 18 European beavers from Bavaria. No one knows for sure who was or why he did it. In fact, They were discovered by surprise Thanks to “the existence of a series of indications, very conspicuous, that reveal the establishment of a small population of beavers in northern Spain.” What we do know is that, although it was tried to eradicate, it was not achieved. And now, he has overflowed the Bajo del Río Aragón course where he found himself and is now considered all the purposes An native animal subject to environmental protections. Beyond the Ebro. If the Pyrenees had worked as an effective barrier to the beaver, once the situation has entered the situation again. A few years later, we had found Castores in the Duero Basin and in the Guadalquivir. What we hadn’t found were still beavers in the Tagus. And in June 2024, two researchers They found themselves With them in Zorita de los Canes, province of Guadalajara. That is, more than one hundred kilometers in a straight line of the closest place where they had previously reported. What is happening here? Because if we stop to think for a moment, we will discover that this expansion of the beavers It is not natural. In 2023, Teresa Calderón biologist calculation that the beavers of Tormes would have taken 40 years to get there by their own means from the closest documented population. In the Andalusian case, or there is a way for these specimens to travel alone the 365 kilometers of southern submeta that are between the stretch of the Guadalquivir where they were found in 2023 and the closest point where we had previously found them. The only rational explanation is that Someone is putting them there. “Beaver Bombing”. Thus (“Bombing of Castores”) is what is called a little rare practice for years: to release groups of illegally managers in areas where they had supposedly lived. And they not only do it without permission: they do it without previous studies, or guarantees, or planning. “As the IUCN establishes, to make a reintroduction of any extinct animal in a territory it is necessary to carry out a series of studies that are almost common sense,” Francisco José García rememberedBiologist and expert in mammals from the climate semm, “we have to know why they were extinguished at the time, under what conditions the animals lived then and if these conditions are maintained. And we must work on the social perception of the species, You can’t do your back things to society. And then? The problem, as happened with The reintroduction of the wolfgetting that “social and political support” is complicated and some groups have decided not to wait. The story gives for A rural thrillerbut he raises many doubts about what will happen in the future. Not only if Castor’s communities will grow in Spain, but this practice will be extended to more species.
