Someone has seemed a great idea to propose a sculpture of a bull of more than 300 meters. There are already cities waiting to host it

by

That the bull is since we have a kind of national symbol reason does not even mention it. But it seems that sometimes it insists on reminding us in increasingly creative ways, so the Spanish Bullfighting Academy Location for a monstrous 300 meter sculpture high that aspires to become a strong tourist attraction. After the rejection of Madrid, Castellanoleonese towns such as Ciudad Rodrigo, Toro, Benavente or Burgos have shown interest in being the hosts of this ambitious project. Colossal dimensions. The proposal contemplates a colossal structure that tripled the height of the Burgos Cathedralwith panoramic viewpoints in the animal’s horns and commercial spaces at its base. The initiative aims to emulate the tourist impact of monuments such as the Eiffel Tower or the Statue of Liberty, but using the bull as a sign of identity. The promoters seek a municipality that yields the necessary land, while the construction costs would be in charge of private companies. More tourism. The project promises to act as an economic engine for the chosen town, attracting national and international visitors. In Castilla y León, a region that has been characterized by a bullfighting tradition, several municipalities have seen a unique opportunity to attract tourism. Ciudad Rodrigo has been the first to show interest, followed by Toro, Benavente, Sahagún, El Maillo, Ledesma and Villatuelda. Even Burgos values the proposal, although Cristina Ayala, mayor of the city, I commented to Antena 3 that saw the “too large” dimensions. The reluctance. For Fernando Martínez-Acitores, deputy mayor in Burgos and Vox militant, building this bull can be “a great emblem” and “a claim for the city.” Naturally, not everyone looks good at the initiative. Daniel de la Rosa, former mayor and leader of the PSOE in the opposition qualifies the proposal as “crazy”, while animalist groups such as Proanbur the consider A provocation that extol animal abuse. In fact, its spokesman, Judith Sánchez, account That “with this bull figure, they seek to disguise something that is far from being.” What comes now. The Spanish Bullfighting Academy is evaluating the proposals received, also analyzing the technical and logistics viability. The selection process will continue in the coming weeks, everything while interested municipalities expect to know the answer. The project needs a lot at least 650 meters long for its construction, and this detail considerably limits the available options.

Surely you don’t know who Sofia Surfers, Fabiana, Álvaro Suárez and Pablo Vera are. But they are the viral summer phenomenon

by

The summer of 2025 is marked by a New type of gossip that is born, grows and expands mainly in Tiktok. Unlike traditional gossip in magazines, television or pink press, this time the epicenter is in networks, created, disseminated and amplified by the users who use the social network: generation Z and millennials. Sofía Surfers, Fabiana, Álvaro Suárez and Pablo Vera do not belong to the world of the show or the traditional show, not even to areas where the celebrities normally arise. But there is no talk of other people in Tiktok. The protagonists. The least interesting of this story is possibly the story itself, But summarizing: Sofia Surfers She is the sister of Lola Lolita, one of the most segated Spanish influencers. It did not belong to the world of traditional fame until shortly before the event, but that has changed: its profile is now full of publications loaded with indirects and key messages. Fabiana Sevillano It is an Andalusian influencer with more than one million followers and is part of the social circle of Sofia and Álvaro. He has publicly confirmed to have a casual and recent sentimental relationship with Álvaro, with an open and direct posture before the drama. Álvaro Suárez He is former partner of Sofia Surfers and a new partner, apparently, from Fabiana. He has tried to maintain a clear attitude and put limits to the spread of gossip. Pablo Vera He is a couple of Fabiana, his name has been mentioned frequently in videos and reactions, and has tried to clarify his version of the facts. Sofia stopped following Fabiana on social networks, what many people interpreted as the confirmation of a betrayal, which Fabiana later confirmed. All this framework has since generated thousands of memes, videos, indirect and debates among their followers, amplifying the viral phenomenon. 11 tricks to dominate Tik tok The impact. Thousands of users have generated a high level of interaction with these profiles. The gossip -related videos They accumulate million visualizations and hundreds of thousands of likescomments and shared: there are explanatory and reagent videos, memes, Duos and Reenactments that They comment or amplify the facts and rumors in ironic or dramatic key. Hashtags like #fabianasevillano, #Pablovera and #Sofiastasurfers are among the most used. The never seen. It is a level of engagement Unusual for previously unknown characters, and that is also organic, decentralized and collaborative, which generates a feeling of community and participation that does not occur in other formats of the pink press. This also generates further propagation speed and more viral strength, which has made the phenomenon born in Tiktok, its impact has spread to other social networks. @javihoyosmartinez Fabiana Sevillano confirms that he looked with Álvaro Suárez: “I like it.” Tell how he told Pablo Vera and responds to Sofía Surferss #Fabianasevillano #Pablovera #Alvarosuarez #SOFIASURFERSS #Lolaloliitaaa ♬ Original sound – Javihoyos Beyond the gossip. In this case the narrative about the protagonists It is not controlled by specialized journalistsbut for the uncontrolled sum of thousands of videos, memes, debates and reactions. This democratizes the birth and evolution of these charactersand makes the target audience of this type of narrative develop A feeling of belonging to all this. Of course, now There are rumors that traditional pink media are beginning to be interested in exploiting this story born in networks. The renewal of the Star System. As the already historical one left us well ‘Save me‘, The renewal of the distributions of these dramas is essential when giving them continuity. In this case, the refreshing circumstance that most of these actors were not previously known (even one of them sister of Lola Lolita) gives them a renewed vitality. And so the idea that there are no modern or ancient issues (a story of infidelities, in fact, is one of the oldest in the world), but forms and spaces to tell them.

Italian workers have entered anger through Stellantis’s investments. Those who have taken Morocco, specifically

by

Stellantis will invest in Morocco. A lot (very much) money. And that will have consequences in your investments in Europe. Especially in Italy where they aspired to see an approach of the company after the departure of Carlos Tavares. Now workers and politicians see how they will continue to vain in favor of North Africa. 1.2 billion. That is the Investment announced by Stellantis For Morocco. 1.2 billion euros that will be distributed in the country to expand the productive capacity of its plant in Kenitra, Morocco, to 535,000 cars per year. That means putting the country’s factory At the height of Vigo’sone of the company’s historical (before PSA). In recent years, Stellantis investments in Morocco have been constant. In fact, the company He began his journey on Moroccan soil in 2019 And in 2020 I was manufacturing just over 200,000 units. In 2030, the forecast is to exceed those more than half a million vehicles produced. Cheap. Stellantis’s intention has been, so far, of factories cheap options for the local market and its expansion by Europe. With the new agreement, the company has also announced that will manufacture hybrid engines in Africaa way to lower its offer of electrified vehicles. Later the known as Smart Car will arrive. This motorist production and three -wheel vehicles will be added to the current production of light grids. The company produces in Morocco Citroën Ami either Fiat Topolino. The latter were reason for controversy to include a flag of Italy which prevented its sale in the country Transalpino because the use of it is limited to products manufactured within its borders. A constant fight. This was just another episode of the open war between Stellantis and Italy. The automobile group It has Italian companies that historically they have had a great weight in the country: Fiat or Alfa Romeo, but also Lancia, Maserati or Abarth, who was born as the sports division of the first of them. Despite this, Stellantis has leaving aside the production of cars in the country. In recent years their layoffs have been famous in Italy and in 2024 the trend was confirmed: 70 years ago that Italian brands in possession of Stellantis did not produce so few cars in the country. The reasons are varied but are distributed between high productive costs and the way to get into the European emission rules. An effort that the company based on fuelmake more electrified And even Pausar Those who were not despite being the best selling. Finally, the automobile industry paws fines until 2027 with a last minute agreement. Italian anger. The departure of Carlos Tavares seemed to give a respite to Italian workers. Or at least, the decision to put Antonio Filosa (Italian) at the head of the company was seen as an approach to a country that had gone from having Fiat as one of its flags Let’s see how your plants They entered the auction to produce Chinese cars. Stellantis’s movement to invest more money in Morocco to the detriment of cars that could have been manufactured in Italy has raised Polvareda in the country. The toughest have been the members of the Government. In Panorama They point out that these have described the Moroccan investment as “absurd”, emphasizing that “for decades, the company has lived the money delivered by the Italian public coffers.” Of course, in the middle they qualify the “predictable” reaction. Also Carlo Cardone, from Azione, He has claimed John Elkannpresident of Stellantis, who complies with The Italian plan That the company put on the table and of which, they point out, no results have been seen, qualifying the movement of “the nth mockery” towards the country by Stellantis. And, at the same time, Samuele Lodi, spokesman for the FIOM union, stressed that investments From Stellantis in Italy they are freezing, they point to the inactivity of the government and emphasize that the situation (with the company) the situation has not changed, but has worsened. “And it emphasizes:” It is the confirmation that they look the other way. “ Smart Car. The harsh statements from Italy take strength after knowing that Stellantis’s investment will imply giving work to 3,000 employees and that it is estimated that the economic impact in the region can exceed 6,000 million euros, taking into account the component supply network from which they have to use. All this will be necessary to build the already mentioned light quadricycles, new three -wheeled electric vehicles and their most affordable hybrid options in the market such as the Fiat Grande Panda or the Citroën C3 whose low price must be decisive for face Chinese competition. Morocco takes strength. All these plans strengthen the Moroccan position as an African car. To Stellantis’s plans we must add the production that Renault has in the country But, above all, the steps that are taking place in the country to position yourself as an alternative attractive to produce electric cars. Morocco is in a key position. Its proximity to Europe allows a distribution that does not more expensive. At the same time, its commercial agreements with the European Union make it a cheap alternative to the south of them but without the economic barriers that it implies, for example, to bring cars from China. In fact, The Asian country itself is promoting investments In Morocco to try to turn the country into a bridge to Europe.

Oil and wine

by

“Those who expect a hurricane appreciate a storm.” The phrase It is from Wolfang Groe Entrup, president of the German Association of the Chemical Industry (VCI) and summarizes well the feeling with which a good part of the political class and economy of the European Union yesterday contemplated the handshake of Ursual von der Leyen and Donald Trump that puts an end (and final?) To the commercial tension escalation of recent months. The EU accepts that its exports to the other side of the Atlantic are penalized by a 15%general tariff. And he will do it without reciprocity and with a small print still pending to specify and promise crucial. In Spain there are two sectors They are already on guard: wine and olive oil. What happened? That after months of pull and loosencrosses of percentages and threats of tariffs of Up to 50%USA and the EU have finally reached a framework agreement for their commercial relations. They are still unknowns, but on Sunday the president of the European Commission (CE), Ursula von der Leyen, and his counterpart Donald Trump, closed A pact which establishes a general tax of 15% to European exports. The agreement was sealed away from the White House or Brussels, in a Scottish golf course that belongs to Trump himself. What did they agree? The key fact is that 15% general tariff that will apply to community exports that cross the Atlantic to the US. The other pillar of the pact is that there will be no reciprocity. The imports ‘Made in USA’ will not face a similar rate in the Union, which also assumes the commitment to buy American energy products for the next years by 750,000 million of dollars and raise your investment to 600,000 million. The agreement nevertheless includes a small print equally important that still throws some doubts. It is known that Washington will maintain a 50% tariff on steel and aluminum, although von der read clarified that this rate could be replaced by a quota system as negotiations are outlined, and that the US will apply exceptions to certain goods that are strategic for the country. What exceptions? The thick stroke is known. During Your intervention In Scotland von der Leyen only gave some clues, without delving into details: “We have agreed zero tariffs for several strategic products. This includes all aircraft and components, certain chemicals, certain generic, semiconductor equipment, certain agricultural products, natural resources and essential raw materials. We will continue working to add more to the list.” His words soon generate reactions and Not a few criticism that consider it unknown or harmful to Europe. In Spain, for example, Pedro Sánchez “supported him”, but “Without any enthusiasm”. Some, like the German industry, have warned of its “negative repercussions” for Europe. Others, like The winemakerthat they have been expectant Before the dialogue between Washington and Brussels, they are claiming that a “zero tariff” be applied to wine and They warn of the serious consequences if a 10%tariff is maintained. Union of Unions assures That, “according to the first transcended information”, the list of exempt strategic goods leaves out “products of great relevance to Spain”, such as wine, olive oil, chees or hams. Is it so serious? According to The data Americans, last year the trade of goods between the US and the EU amounted to 975,000 million dollars, with a flow of European imports well higher than that of exports. In 2024 Spain exported goods worth more than 21.200 million And there are studies that indicate that the impact of tariffs would not be excessive: According to the IMFthe direct impact for our country is one tenth of GDP for every 10 percentage points of American tariffs applied to the European Union. “A priori, the direct impact would be limited. Total sales to the US represented only 4.7% of the total Spanish exports in 2024, so it would be a limited affection. However, it could be relevant in the sectors with a greater exposure to the American market,” warns The Chamber of Commerce of Spain. Among them there are two keys for the weight that the US has in its exports: The wine and olive oil. As a reference, it is estimated that only between Spain and Italy export 65% of the oil that the country needs. What does the wine sector say? It is expectant. “It seems that in the next few days there could be negotiations for certain agricultural products, zero by zero, which is what the European and American sectors have been asking for,” says José Luis Benítez, of the Spanish Wine Federation, in statements collected today by The country. “If there is any exception, we hope that the European Commission (CE) understands that the wine should be one of them.” The European Committee of Viticultural Companies already He has claimed to the Union and the United States that its agreement includes wine among its goods with “zero tariffs”, which a priori, as advanced yesterday in Scotland, will include some agricultural products. “The EU-EEU Wine Trade has been a beneficial mutual relationship,” claims. “For every dollar that Europeans get selling wine to the US, the American distribution and the hospitality sectors get 4.5”. And the oil? Asaja Jaén spokesman, Luis Carlos Valero, Recognize That the imposition of 15% is “totally negative” for their interests, although at the moment it is cautious: “You have to wait to really see how these tariffs are applied.” In the past, the olive oil sector has already faced taxes imposed by Donadld Trump, but only the packaged product penalized, so they recognize that if that same pattern was repeated the impact would be “minimal.” “The vast majority of exporters who go to the US have located the packagers and takes bulk, therefore we would be exempt from that tariff,” reason In an interview with Europa Press in which he insists that he is still “very soon.” “You have to wait to really see what this is, how it applies.” Are there … Read more

It is a first step to understand why we exist

by

The most elementary question that human beings ask ourselves since we are here is simply: why do we exist? According to the best theories about the origin of the universe, We should not be here. The Big Bang should have created identical amounts of matter and antimatter, which would have annihilated each other in an energy flash, leaving an empty cosmos. And yet, here we are, in a universe made of matter. Short. The key to our existence lies in a subtle asymmetry, a small trap in the laws of physics that favored matter over antimatter. Now, the CERN LHCB team has announced the first observation of this asymmetry in the bariones, the particles that make up everything we see: stars, planets and ourselves. It is a milestone that we had been waiting for decades, and that after its Publication in Nature magazine Open a new and fascinating way to solve the mystery of our own existence. The enigma of the material universe. The Soviet physicist Andréi Sájarov saw it clear in 1967. For the matter to prevail above the antimatter after the Big Bang (so that a universe like ours was born, in short) three conditions should be met, including the violation of the load-partner symmetry. Load symmetry (c) means that if you change a particle for its antiparticle (for example, an electron for a positron), physical laws should not change. Parity symmetry (P) is like looking at the process in a real mirror, investing space coordinates. Combined symmetry load-partity (CP) implies that a physical process is indistinguishable from its “antimatter version” in the mirror. If the CP symmetry were perfect, the balance between matter and antimatter would never have inclined. CP symmetry violation means that the cosmic mirror is slightly broken. Subject and antimatter do not behave exactly as specular reflexes. The fundamental piece that was missing. This phenomenon had already been observed for the first time in 1964 in particles called inns, formed by a quark and an antiquark. But there was a key piece of puzzle: it had never been detected in the bariones, formed by three quarks. It was a key piece because ourselves are barionic matter: the protons and neutrons that constitute us are bariones. An imperfect reflex. The CERN LHCB team, one of the great detectors of the great Hadron collider, specializes in studying particles that contain a type of heavy quark called “Beauty” or “Bottom”, in which the effects of the CP violation are expected to be more pronounced. For this investigation, physicists focused on a specific particle: the Lambda B zero (λb0) barion, a kind of heavy cousin of the proton. Scientists analyzed billions of collisions In data from 2011 to 2018observing how this particle disintegrated in four lighter: a proton, a kaon and two pions (λb0 → pk –π+π−). The key to the experiment was to compare the rate of this disintegration with that of its antimatter twin, the disintegration of the anti-barion lambda b zero (λˉb0 → pˉ k+π-π+). If the CP symmetry were perfect, both disintegrations would occur with the same frequency. But it is not so. The LHCB team measured a clear and statistically robust difference. Are we facing new physics? The results have a statistical significance of 5.2 sigmas. In particle physics, an observation with more than 5 sigmas is considered a full -fledged discovery. It is the first time that a barion and its antibarion are observed do not behave identically. The mirror is broken, also for particles that form the tangible world. This discovery is, in the first place, a spectacular confirmation of the standard particle physics model. This model, our most complete theory on the subject, predicts that CP violation must occur in both inns and bariones. The fact that it is finally seen in barions reinforces our current understanding of physics. However, and here comes the most exciting, it is also the beginning of a new chapter. The observed violation is insufficient to explain the enormous mastery of the matter we see in the cosmos. There must be Another source of asymmetrysomething that the standard model does not contemplate. Physicists have confirmed that the universe does not deal equal to matter and barionic antimatter, but hunt continues.

That the purchase basket It has become more expensive In recent years it is no secret. Consumers seek to save Comparing prices and sometimes moving away from cities to go to surfaces where they have more affordable products. This is what is happening with this 30 kilometers from Madrid after a Video on Tiktok. Low prices. “The cheapest supermarket in Madrid. Almost everything to less 1 euro.” Thus begins the video that has been viralized in question (although There are more). In it, the creator shows us many products that cost less than 1 euro, from melons, watermelons, tuna cans and cleaning products. To olive oil, One of the most expensive productsit costs only 3.39 euros. The paste: it is about 40 minutes by car from the center of Madrid, but that has not prevented many Madrid people from leaving the road to save a little. How do they. The supermarket is called Mermax and has two headquarters in Madrid, one in Griñón and one in Meco, although it is that of Griñón that is mentioned most in social networks. According to The Spanishbelong to the supermarket group the point and, to get those low prices in first brands, they use a wholesale sale model without intermediaries. “It’s like an autonomous cash & carry, but without having a card,” says Cintia Ramiro in his video. In Google’s reviews we see Some comments which says there are also products with next expiration date. Divided opinions. Diving through Google’s reviews we find comments of all kinds. Many Good prices stand outbut others They don’t see it so cheap. In the videos it may seem that all products are worth less than 1 euro, but the comments are intuited that they are only some offers. There are also several clients who point to It is not worth going so farsome even call it “misleading advertising” Influencers Low-Cost.

There is an undisputed leader. Although they arise supermarkets that presume to be cheaper As Mermax, the reality is that they have few already often are only in a very specific area. In Spain there is a supermarket chain that overwhelms And it has stores throughout the country. We talk about Mercadona, which has a 26.7% market share, far ahead of the second since Carrefour occupies with 9.2%. In addition, almost all Spaniards (93%) have ever bought in a supermarket in the Juan Roig chain.

1,800 years ago China had one of the most intriguing technologies. Now is the point of resuscitating the dragon that detects earthquakes

by

Almost two thousand years ago, during the Han dynastythe Chinese scholar ZHANG HENG He designed a device that, according to historical chronicles, could detect distant earthquakes and even point out his address. That invention, called HouFeng Didong Yiit was a mechanical gadget that had the dragon as the main actor. Now China is about to resurrect what a legend was believed. A erased prodigy of time. We talk about a mechanical system (an ornate vessel surrounded by eight dragons with suspended bronze balls, oriented towards mouths of toads) that would have been able to register imperceptible earthquakes in Luoyang, the imperial capital, with a precision that “touched the divine”, according to THE BOOK OF THE Subsections. However, its sudden disappearance of historical records and the impossibility of replicating it exactly led to its total elimination of the Chinese educational curriculum in 2017, relegating it to the field of legend. Today, a team led by Professor Xu Guodongfrom the Hebei Disaster Prevention Institute, seeks to recover not only its operation, but also Your place in history of science. The rebirth of a prodigious machine. To the question: How the hell will they replicate it? The researchers They explain that from ancient literary fragments and principles of modern structural dynamics. Thus, Xu and his team have proposed a functional model of the earthquakescomposed of three key subsystems: structure of excitementtransmission and closure. In the heart of the device he was A “Capital Pilar” that should not be interpreted as an unstable column, but as a pendulum -like arm (a kind of gigantic stick anchored to the ground) that amplified the seismic vibrations. With just 1 mm of displacement at the base, the tip of the pendulum moved up to five times more, activating a “L” levers system that released a ball in the mouth of the toad corresponding to the direction of the epicenter. A blocking mechanism prevented other dragons from reacting, thus respecting the Original description of “a dragon who speaks and seven that shut up.” Mathematical Wisdom. Team simulations indicate that the system responded reliably to displacements just 0.5 mmwithout emitting false alarms. Although modern knowledge of propagation of seismic waves suggest that a single instrument cannot determine with total precision the direction of the epicenter, Xu argues that the Historical records coincide with optimal geological alignments. As proof, appointment The Longxi earthquake From the year 138 AD, when the instrument would have detected a tremor 850 kilometers away, without feeling in Luoyang. The initial skepticism of the officials vanished when messengers on horseback confirmed The shaking days later. Even more revealing, he explains, is the jump in the frequency of earthquakes registered in the capital after the implementation of the artifact: in the previous 8 years they were only documented three local earthquakes; In the 58 years later, there were 23, in a region considered low seismicity. Zhang HENG: astronomer and political victim. ZHANG HENG It was not any inventor. His appointment as a great imperial astrologer in 115 (a position equivalent to the director of a modern national observatory) and his creation of an armilar sphere Able to map the sky with precision, they prove their domain in mathematics, astronomy and mechanics. But his invention could have been politically uncomfortable. In a context where natural disasters were interpreted as signals from heaven and threats to the mandate of the emperor, an instrument that “predicts” earthquakes could have been seen as subversive. Some scholars suggest that HENG’s abrupt retirement in 138 and his death the following year They were not casual. Xu duck that the loss of the original earthquakes (along with its technical diagrams) could be due to wars, political chaos or even the greed of powerful aristocratic families that would have hidden its existence. Recovered legacy. In a gesture loaded with symbolism, xu He recalled that only two bronze objects have been defined in Chinese history: Nine cauldrons of the Xia dynasty and this earthquakes. Now, the objective is ambitious: rebuilding the instrument using only materials and technical Advanced knowledge reached in ancient China. Beyond the material restoration, the project aspires to reinsert this jewel of engineering in the global narrative of science, as proof that humanity had already tried, long before satellites or artificial intelligence, unravel the Mysteries of the tremor From Earth. Along the way, the Heng’s featerased for centuries of oblivion, it could be closer to recovering its place among the great milestones of human thought.

A large mass of cold air on our heads

by

The first half of the summer of 2025 was of intense heat. Now, those days seem distant for many: temperatures have descended significantly and everything indicates that they will remain for a while. The responsible: a large mass of cold air. A cold dough. Temperatures this week They will continue to be low In a good part of the country, according to expert forecasts. At least for what would correspond to this time of the year: the last days of July and early August is precisely where the cannula is usually given, the summer point in which the temperature peak is reached. The reason is in a large mass of cold air located on Western Europe and that also covers part of the Iberian Peninsula. Behind this situation are the undulations of the polar jet. A more undulating jet current of what is usually common is responsible for bringing to our latitudes this mass of cold air and the consequent atmospheric instability. More than fresh air. The low temperatures at this time of the year are striking in themselves, but they are not alone: in some areas it is expected that rainfall and storms continue during this week, although for now it is not expected to reach the intensity of The episodes seen last week. The forecasts From the State Meteorology Agency (Aemet) they talk about “abundant” rainfall today in the Eastern Cantabrian and North of the Pyrenees, With yellow warnings activated in eastern Catalonia. A situation that will be similar tomorrow, with rainfall also in the area of Cabo de la Nao and again with notices for rains activated on the Catalan coast. On the border. The situation will not be homogeneous. Not much less. While the north of the Peninsula and the Mediterranean basin experience a thermal decrease, temperatures will exceed the fork of the 34º to 36º in the southwest quadrant, especially inside. Aemet has activated various notices due to high temperatures in these areas, among which orange notices (important risk) in the valleys of Guadiana and Guadalquivir.
