Wine and beer have been moving tourists from all over the world for years. Now also the bread

by

It doesn’t matter if we talk about Madrid, Barcelona, ​​Zaragoza, Oviedo or Vigo. In any moderately large city in Spain (as in many other countries) it is difficult to go out and not find a place to buy A bread barbuns or a cross at a reasonable distance. They sell it in the neighborhood pastries, but also in supermarkets (grades and small) and of course in chains such as Starbucks or Dunkin. That does not mean that there are people willing to take the car or even get on a plane to try a special bread. In a world in which more and more travel And it is no longer surprising to speak oenological tourism and gastronomic excursions or dedicated to handmade beer (Craft Beer-Tourism) A new modality opens up: the Bakery tourism. Traveling with the palate. There is nothing written about trips. Nor about tourism or vacations. There are those who plan their getaways thinking about Paradisiac beacheswho prefers to spend their days free climbing mountainswho opts for cities, who prioritizes Quiet places To rest … and who directly decides his destination “listening” to his palate and the belly. It is nothing new. He wine tourismhe Beer-Tourism and the Gastronomic Tourism In general, it has been practicing for years and has become a business that moves billions of euros. According to Turespaña, only in 2022 (an exercise still marked by the pandemic) the tourists who visited Spain 22.7 billion of euros in en-gastronomic activities, which makes them one of the main sources of income for the sector. And of those that grow the most. @Nat.Majira Is called #LANNAN And it is in Edinburgh, it always has a tail and the #Croissant and #Painauchocolat They are your specialty 💖 #Edinburgh ♬ Original Sound – Nat.Maquirira Objective: Good bakeries. Not all travelers (and that includes from visitors from other countries to locals who plan small escapes) are looking for wineries, breweries or Michelin star restaurants. There are those who prefer sweet flavors and what they demand are handmade cupcakes or bakeries. A special bread. A brioche with its cream filling. A Babka particularly appetizing. A honey croissant. A Pain Au Chocolat. A cinnamon bun. The list adds and continues with pastry that travelers are looking for guided by Instagram or Tiktokspecialized forums or guides such as ‘Britain’s Best Bakeries’. Welcome to “Bakery Tourism”. The trend is extended enough to The Guardian I just dedicated A wide report in which he speaks of the “extraordinary boom of the Bakery Tourism“, a term that could be translated as” bakery tourism “or” pastry. As an example, he quotes an Edinburgh bakery, Lannan Bakerythat despite carrying open only a couple of years has managed to become a mecca of Bakery Tourism. “We had just received a person who came from Canada. And last year there was another from New Zealand who booked his trip to come,” says his pastry. Your Instagram profile adds around 103,000 followers And in Tiktok they can be found A good handful of publications about their buns and tartlets. @kimchiarepa Most famous bakery of Korea🇰🇷. #korea #Korea #성심당 #koreanbakery #Bakery ♬ Magnetic – Illit Does it happen only in the United Kingdom? Not at all. Arrives A quick search In Google to see how Pan and Bun tourism has its space share in other countries, including Morocco, Japan, the United States, Portugal, Türkiye, Germany or Argentina, such as I quoted recently The specialized website Travel and Tour World. Its logic is simple: cities take advantage of the attractiveness of pastry and traditional sweets to boost as a tourist destination. Nothing that did not have been doing wine warehouses, breweries and localities with Michelin star restaurants or culinary fairs for years. In the case of Portugal, for example, he quotes the popular ones Nata or Belem pasteswhich have already inspired several Guides and Routes By Lisbon focused right on that: show tourists where they can try them. Another word: “bbangjisullae”. Another country in which bread and tourism have marinated well is South Korea. Recently Korea Joongang Dailyk It echoed How there are Koreans traveling hundreds of kilometers, taking trains or spending the night away from home, in Airbnbs, to enjoy the best local refuel. There the trend has its own name: bbangjisullaea mixture of words BBANG (“bread”) and Seongjisullae (“pilgrimage”). And that does in some way those who practice it: a kind of “pilgrimage of bread.” The phenomenon also connects with an upward business in the country, that of the bakery, valued in around 5,500 million dollars and that according to the forecasts handled by the sector in mid -2024 faces a growth horizon. The data The food statistical information system also shows that the number of bakeries has grown clearly in the country: from 24,777 in 2020 to 28,070 in 2022. The franchisee premises however stagnated. Promoting the economy. That last nuance is interesting. Bread, buns and crosss can be bought in many businesses, from large pastmarkets baking chains; But the “bread pilgrims” look for a certain type of product. And how it reveals The report of The Guardian, They often resort to local businesses that can be far from the big cities. In Daejeon, the fifth largest metropolitan area of ​​Korea, stands out for example Sungsimdagfounded as a small bakery specialized in buns In 1956 and that has expanded since then until becoming a local icon. So much so that, according to the local tourism office, it was The most visited place by tourists who arrived in the city throughout 2022 and 2023. A good part of the surveyed travelers say that the pastry was one of the reasons that led them to know Daejeon. It is not a unique case. Something similar has happened in other locations of the US or of Australia. Images | Mark Ramsay (Flickr) and WEI (UNSPLASH) In Xataka | More and more people are going on vacation simply to sleep

Its creator has taken eight years to finish it

Sometimes, the most stimulating phenomena of the video game happen behind the back of the great media campaigns and prefabricated successes. Simply, an extraordinary quality game or with immense playable possibilities grows with the mouth to mouth of the users. And when it reaches the media, it is already the sensation of the environment. It has happened to ‘Blue Prince‘, And it is the great current secret success of video games. Simple but matador. What makes ‘Blue Prince’ an overwhelming concept game is that he finds a point where two apparently opposite mechanics are crossed. On the one hand the static puzzles of ‘Myst’ games. On the other, that the game is a Roguelitethat is to say: each game is completely new, death is permanent and the objective of the game, exploring a house of 45 rooms in search of number 46, which is secret, is reset with each restart, having to start exploration again every time. The ‘Balatro’ Way. Every time you try to leave a room, the player has three rooms at your disposal to locate. Not only will they tell a fascinating and increasingly sinister story between the lines, but they have their individual characteristics: not all of them open to the first, not all have the same ways of exit, if they have them. They could be three letters to choose from a deck, and in that sense the game remembers’Balatro‘, the last feeling of the industry. And that he toured a path very similar to this: released by Bajini, without great campaigns around, and thanks to the mouth of the players, excellent notes and the runrún on social networks became the game of the season. Eight years. It is the time that its creator, Tonda Ros. Inspired by the documentary ‘Indie Game: The Movie’, he decided that he would set up a game with very elementary development tools, such as the Unity engine. His inspiration were games like ‘Gone Home’ and ‘The Witness’, as Bloomberg said. In 2016, Ros began to develop a prototype of ‘Blue Prince’ with the plan to invest only six months in development, but one thing led to the other and ended up leaving the job and commissioning part of the tasks, such as the art direction or the soundtrack, to other creators. Since 2021, with the already playable prototype, he has basically dedicated himself to balance the difficulty. But … What does ‘Blue Prince’ have? Basically, a mixture impossible to describe in words: on the one hand rigid mechanical, almost outdated for puzzles; on the other, the total unpredictability of the Roguelites Modern, where each game is completely new. Contemplative and at the same time mysterious, with a story that unfolds wonderfully and without carrying the player at any time, ‘Blue Prince’ has become one of the best valued games of the moment. Criticism loves him. ‘Blue Prince ‘holds An average of 92 in Metacriticthat is, it is the best valued game from 2025 to date. In other aggregators, as opencritichas an impressive 98 after 63 criticism, and an average of one in three reviews providing the maximum possible score. Many media already describe it as Important matching contender of the year. If something like this happened in the next game Awards, it would mark a trend worthy of being taken into account in the industry: after the triumph last year of the superb ‘Astro Bot‘, we could be seeing a withdrawal of Blockbusters and a turn players preferences towards titles (much) more modest. And sales endorse it. ‘Blue Prince ‘has been played by approximately 150,000 people on all platforms. The bulk of its sales have produced, however, in Steam, since those of PlayStation and Xbox are scarce due to their availability in Game Pass and PlayStation Plus. Sales are not official, but estimates They are between 77,000 and 162,000 copies: as the game debuted in the Seventh place in the Steam Sales Weekly Top In its launch week, it is believed that their digital sales have been superior to the average for such a game. ‘Blue Prince’ reached a historic peak of 19,243 simultaneous players in Steam on April 20, 2025, and currently is around 15,000 players connected simultaneously. A authentic and small miracle. In Xataka | The indie sensation of the moment is ‘unpacking’, a video game that extracts pixelated gold from one of the most boring activities in the world

We have been asking who is the oldest person in history to be recorded on video for years. And maybe it’s a Pope

by

The history of art is the history of its protagonists. And that includes both its great creators, so let’s talk about painting, sculpture, poetry or music, as well as their patron, muses and models. Da Vinci It has been fascinating for years to historians, but it is difficult to address their biography without explaining at least past who was Lisa Gherardinithe woman who probably inspired the celebrated ‘Mona Lisa’. The same goes for the enigmatic Elisa to which Ludwig Van Beethoven dedicated her catchy Bagatela Woo 59 either Margherita LutiRafel’s great muse. With photography and cinema something similar happens. And although their origins are more recent than those of painting, music or sculpture, historians who take care of their study face questions equally complex and fascinating: who was The first person to go out in a photo? And the oldest? Who is it The oldest voice captured in a support that allows us to reproduce it? And if we talk about cinema, Who is the oldest person filmed? Did technology and art arrive in time to capture in a recording the gestures and movements of someone born in the eighteenth century, which saw the French revolution wave War of Independence from the US? And if so, can we see it? The “vestustos” of the image and sound The question is fascinating because photography has allowed us to see static images of people born in the 18th. This is the case of Conrad Heyera veteran of the US War of Independence that was born in 1749. He was portrayed in 1852, with more than 100 years, thanks to the technique of daguerreotype, so There are those who believe which is the most ancient person (not the first photo, eye) photographed. The title nevertheless has some “but” than another. Heyer’s image is fascinating, but Other experts think that if we talk about vetustez the merit of being the oldest person portrayed with a camera is John Adamsa worker of Worcester born a few years before Heyer, in 1745. Other sources speak of a slave named Caesar, protagonist of a 1851 daguerreotype conserved in New York Historical Society and who in theory was born in New York in 1737. If what we are talking about is about the voice, the story is equally fascinating. We keep A recording 10 seconds from 1860 Taken with a spell and that is attributed to Édouard-Léon Scott by Martinvillea French inventor born in the Paris of 1817. Again if what we are talking about is of antiquity, perhaps The most ancient voice that we keep engraved is nevertheless Helmulth von Moltkea Prussian marshal who lent several recordings at the end of the 1880s. The surprising thing is when Moltke was born: in 1800. And at the dawn of the cinema? Who is the oldest person than we keep a moving recording? The answer is complicated again, although equally surprising. At the end of the 1870s EADWEARD VERYBRIDGE elaborated in A protopeic in which you can see the gallop of a horse with your rider. Your identity? Some sources They point to C. Marvinborn In 1839. If it scratches in the origins of the celluloid it is, however, to meet even older “actors”. And also some other surprise. For example, It is usual that when talking about the oldest person ever filmed, the looks are directed to one of the great personalities of the nineteenth century, the Pope Leo XIIIwho also holds the merit of having been The first Pope filmed. The movie, by William Kennedy Dickson For the Biograph company, was shot in 1898 (there is who attributes it to Vittorio Calcina and the date in 1896) and although it is fascinating and iconic, any Oscar will hardly win. After all, he shows the Supreme Pontiff in more or less everyday situations: on a car or sitting in a chair in the Vatican gardens while making a blessing in the camera. The really surprising is not however What does Leo XIII doif it is the first pontiff recorded in a movie or who, when and where he took those images for history, but the year of birth of the Pope: Leo XIII He was born in the Lacio region with the name of Gioacchino Vincenzo Raffaele Luigi Pecci in March 1810. That is, for ten years he was not a character of the XVIII. Does that become the oldest person ever filmed? Depends. For some The answer is yes. For others that merit is not so clear. In the articles that address the subject, there is talk of a Rebecca Clark allegedly born in 1804 or Mammy Louof the same year. However, there would be an older candidate, a figure that once aroused much less interest than Leo XIII and to which, therefore, it is also more difficult to follow the historical clue: dismiss. That your name does not tell you anything is understandable. Despina was an old woman from the Balkans who among other tasks dedicated the hours to spinning wool in the company of her daughters. In 1905 it ended up portrayed in A brief movie that lasts a few seconds. The important thing is its date of birth: it is said that Despina was then 114, which would have been born at the end of the 18th century, In 1791. How did an old woman from Avdella end, then part of the Ottoman Empire, recorded spinning wool for the subsequent and turned into a key figure in the history of cinema? Simple: because it was the grandmother of Ianachia and Milton ManakiBalkan cinema pioneers and film authors ‘The weavers’. We already said it at the beginning: the history of art is the history of its creators … and of their circumstantial protagonistsamong which there are farmers, war veterans, shoemakers, centennial spinners and even a 19th -century Pope.

China had been buying tons and tons of soy to the US for years. A country has won in place: Brazil

by

China likes American soybeans. A lot. Every year matters from the fields of Illinois, Minnesota or Iowa Millions of tons From a crop that is consumed directly in pod, it is processed or is intended to feed cattle. The problem is that in full Commercial Warand with him Tariff crossing Of more than 100% applied by Washington and Beijing to their respective exports, that American grain will probably stop being attractive in Chinese factories. It has already happened years ago, during the commercial war of the first mandate of Donald Trump. And then, as now, China began to look with increasing interest other sources of soybeans. Which is it? Argentina and especially Brazil. A figure: 27 million. He Tariff pulse Between the US and China, which has resulted in a rise in encumbrances of more than 100% to the commercial flow in both directions, threatens to hit a key merchandise: soybeans. The reason is very simple. American farmers sell a lot, a lot of soy to the Asian giant. In 2024 that flow exceeded 27 million tons metrics, with a value of 12.8 billion dollars. Moreover, oleaginous seeds (group that includes soy) were one of the main US exports to China in terms of value. Two years ago, the US-China Business Council calculated that, together, oleaginous seeds and cereals represent the largest export of the US to China, with a value that was then ascended to 25.4 billion. To have a clearer image of what soybeans supposes in those accounts, The New York Times Precise that last year mobilized nine cents of each dollar of goods that the US sold in China. USDA data shows that the Asian country monopolizes Something more than 40% of the Total US Soy Sales. A percentage: 135%. That is the rise of tariffs that will have to deal with that huge flow of American grain to China from now on. The percentage is the sum of two increases: the 10% imposed by Beijing in March to the importation of certain agricultural products and The extra 125% With which, already in recent weeks, he responded to the escalation of the commercial war with the US. The question they leave by driving those rise in levies is obvious: how will it affect the flow of American soybeans? Will it remain attractive to the Chinese market with that 135% rates? The issue has generated expectation between The analysts And of course Farmers worry From the US, a good part of them installed in states that, such as Iowa, Indiana or Ohio, are important soy producers and last November they voted for Donald Trump. “We deal with bad weather, pests, tractor breakdowns,” he lamented recently Heather Feuerstein, owner of a Tnyt Michigan farm. To all these challenges are now added tariffs, which in their opinion suppose “a threat” for their way of life. One date: 2017. While the tariff pulse with which he has started 2025 is being particularly intense, it is not the first time that Feuerstein and the rest of his colleagues are seen in a similar situation. Years ago, during his first presidential mandate, Trump has already started a commercial war with China that fully affected soy exports. As? Leading Beijing to bet on other suppliers and reducing the flow of grain ‘made in USA’. Nikkei precise which in 2017 was behind almost 40% of Chinese imports. Although the commercial flow remains high, in 2024 that figure was already 20%. Recently the CNN elaborated A detailed graph in which it shows that between 2017 and 2018 the US soybeans exports to China foster from 31.7 million metric tons to 8.24. Since then the flow has been recovered until it is located at 27.2 last year, although the data remains below the one registered before Trump’s first mandate. In general, from the Department of Agriculture (USDA) esteem that the commercial war caused direct losses to the US agricultural exports that exceeded the 27,000 million of dollars between 2018 and 2019. A country: Brazil. Every war has its winners. And the commercial open years between the US and China has a very clear one if we talk about soybean trade: Brazil. He same graph The CNN shows that as US exports lost bellows those of Brazilian grain shot. From 2016 to 2018 the flow destined for China rose to 68.6 million metric tons and in 2024 the 72.5 million tons were exceeded, well above the US export levels. In general, it is estimated that in recent years China increased 35% Its annual imports of Brazilian soybeans while they reduced the Americans by 14%. If the growth is ever seen the growth was Very superior. What does that mean? That in 2017, Brazilian soybeans supposed about 50% of its imports for China, now Round and 70%. A reflection “will have to acquire more”: “If you can’t get it from the United States, you will have to acquire more than Brazil. And they will have to pay more,” Comment to Tnyt Neusa Lopes, agricultural tour directive, an outstanding soy producer of the state of Mato Grosso, in Brazil. The truth is that the commercial war comes after, at the end of 2024, XI made a state visit to Brazil to strengthen ties between the two countries and the Brazilian Association of Soy Producers I confirmed recently that at the beginning of the month the Asian giant signed contracts for millions of tons of grain. Beyond Brazil, There are analysts They point out that Beijing could rely on Argentina, Another great producer. Between what happened eight years ago and the current scenario there is however An important difference. After years of commercial flow between China and Brazil, today the first one has much easier to stock up on the crops of the South American country. The Asian giant has invested in warehouses, railways, ports and other infrastructure that facilitates the transfer of Brazilian soybeans in Chinese ships. The clearest example is the great open terminal this year in the … Read more

We have been reading about the danger of arsenic in rice for years. So much that we run the risk of not believing it in the worst possible time

by

Arsenic is one of the best known toxic elements. The fact that traces of this element can be found in the rice we consume sounds more alarming than it really is: today only very high consumption of this food could involve health risks. The problem is that this can change in the future. Growing concentrations. A new study has pointed out that the increase in temperatures and carbon dioxide concentrations (CO2) in the atmosphere can favor the absorption of arsenic in rice crops. This would translate into a greater presence of the element in the dishes elaborated from this cereal. A change whose impact could be significant around 2050. This increase in arsenic concentration could especially affect the population in Asia, where rice represents a higher portion of the food consumed. “Our results suggest that this increase in arsenic levels could significantly raise the incidence of heart disease, diabetes, and (cause) other non -carcinogenic effects,” he said In a press release Lewis Ziskka, co -author of the study. The risk of arsenic. Arsenic is considered a heavy metal despite chemically belonging to the semimetal group. He Risk level which implies its presence depends on several factors, for example on the fact of the molecular structure in which it occurs (its organic structures are less dangerous than the inorganic ones). And, of course, it depends on the dose. The risk posed by this element has to do with its accumulation in our body. Its presence can lead to problems in development among the youngest, and in adults it has been related to skin disorders, bladder and cancer of lung. 28 Rice varieties. The team responsible for the study analyzed the effects on the rice of an average increase of 2º Celsius at the temperature and the associated increase of atmospheric CO2. Did it in 28 varieties of this cereal, modeling the evolution of its inorganic arsenic content over 10 years. From there, the team estimated the health impacts that this accumulation could produce in the populations of seven Asian countries around 2050. The result: a drastic increase in cancer cases and especially the cases of bladder cancer. Among the countries studied, China would stand out, which could see more than 13 million new cases of cancer associated with arsenic exposure. The details of the study were published In an article In the magazine The Lancet Planetary Health. Not everything is lost. In its study, the team raises some possible adaptation measures dedicated to reducing the future impacts of this problem. The team suggests hybridar varieties of plants to favor those that absorb less, introduce improvements in soil management in rice fields, and improve food processing practices. They also propose consumer -centered measures: education and minitor, they explain, they could play an important role in reducing the impacts of this growing presence of arsenic. The occasional alerts we receive regarding arsenic levels in rice could make this more difficult, by turning this problem into a “Pedro and the Wolf story”: a non -existent problem that we pay attention today could become a real problem that we ignore in the future.

We have been asking us for years, we will eat in space. Now we know that at least miso

by

The space has become in recent years a more and more open place, not only reserved for a handful of trained professionals but also to anyone who can afford one of the nothing cheap passages that can lead one to cross the last border or even put it into orbit. Now, if we want to continue taking more and more people to space, solve The question of food It will be a key step. Miso in space. A group of researchers Miso has managed to ferment In a mission to the International Space Station (ISS), demonstrating that the food fermentation process is possible in environments like this. The experiment is a small step towards improving habitability conditions in space trips. From koji to miso. The miso It is a popular seasoning in Japanese cuisine. It is prepared from fermented soy, barley or rice grains, and salt. Soy fermentation is performed through a Koji fungus culture (Aspergillus oryzae), a fungus also used in the elaboration of the Sake. The team wanted to verify if this fermentation was possible in orbit, since microgravity conditions or cosmic radiation could affect the growth capacity of microbes in food. To check it, they sent a sample to low terrestrial orbit, to the ISS, For 30 days. As a control, they also fermented samples of the same lot on the mainland, at the MIT headquarters (Massachusetts Institute of Technology) and at the Technical University of Denmark. Fermantado. The experiment was successful. When the sample came to Earth, the team studied the state of microbial communities, aromatic compounds and sensitive properties. They detected, yes, some changes. “Fermentation (in the ISS) illustrates how a living system on the microbial scale can prosper through the diversity of its microbial community, emphasizing the potential of life to exist in space,” stood out in a press release Maggie Coblentz, who collided the study. Nuts. Trying things in a laboratory is usually a bad idea, but this time the team should also verify the taste of this space miso. They first verified that the orbital recipe contained the same aromatic compounds and amino acid profiles similar to terrestrial miso. Those who tested the space miso explained that the taste was good and similar to that associated with this product. They noticed that, a greater flavor of nuts and more toasted. The details of the study were published In an article In the magazine iscience. Expanding the menu. The experiment can be used to improve access to new flavors among people traveling to space. Today the foods that can be consumed in space are limited by factors such as the amount of water that we can lead to the space or product development requirements. The possibility of fermenting products in orbit will expand The limits What we can eat in space (e Even on other planets). And it is not only about the possibility of introducing new flavors: fermentation is a process that humanity has taken advantage of during millennia to preserve food and increase its useful life through transformation. Not so sterile. As Explain COBLENTZalthough we tend to see ISS as an aseptic and sterile environment, the experiment also demonstrates that microbial life is possible in these environments. This also implies bioethical issues about the fact that, if humanity ever becomes an interplanetary species, it will not do it alone but accompanied by both plants and infinity of microorganisms that can settle in these extraterrestrial environments.

This bridge built by China is so high that two Eiffel tower fit under it. And they have built it in just four years

by

We have been having bridges from prehistory. From that tree That someone would use to connect two sides to the majestic Roman bridges, humanity has evolved while doing the bridges he built. The more recent techniques They allow us to connect extremes that are separated by tens of kilometers, but Talk about bridges It is currently looking at China. They not only have The longest maritime bridgebut also the highest in the world. It is the Bridge of the Grand Canyon of Huajiang and the most surprising thing is not that under it two Eiffel Tower enter one over another, but that it has only taken four years to lift it. Necessary. The Gran Canyon of Huajiang is located in the province of Guizhou. It is an area that, traditionally, has been isolated from the rest of the area for a reason for weight: more than 90% of the territory is mountainous terrain that hinders communication. For centuries it did not have much importance for the rest of the empire, but China has been raising infrastructure (and also excavating) to demolish those geographical barriers. Puzzle. The objective of the government is to connect rural areas with urban centers and, in this case, you had to get the Liuzhi-Anlong highway to raffle the mountains to speed up transport times. The only way was through a bridge, and after an analysis period, in 2022 They started The construction of the great bridge. It was not going to be simple: it should not only be at a considerable height, but to have a length of almost three kilometers. And the problem was not so much to create the suspension bridge, but to raise the necessary materials. To do this, implemented Advanced technologies to raise steel beams by up to 215 tons of weight and, despite the difficulties in the field, the works have gone at a pone rhythm. To all fuse. That is what usually attracts the attention of these Chinese infrastructure that, weighing some exceptions such as half -building abandoned skyscraper For years, they are an example for the rest of the world. The works advance with speed and, if At the beginning of this year We already saw the two towers of 262 and 205 meters on both sides of the bridge, as well as the cables of 9,000 tons each, now we observe that they have already built the section that joins the ends. The length Total of the bridge is 2,890 meters and the main section, which is among the towers, has a length of 1,420 meters that positions it not only as the highest bridge in the world (it is 625 meters from the ground, reaching the end of the towers at 776 meters), but as the longest hanging section built in the mountainous area. The comparison with the height of the Eiffel Tower is interesting, but almost two Empire State Building would also enter. The technology used in construction is also interesting. For example, when the concrete pour, Guizhou Bridge Group builders devised a system of pipes that pump cold or hot water depending on the outer temperature to ensure that fresh concrete dried in the best possible conditions to avoid cracks. And, to guarantee maintenance, the cables have sensors that measure vibrations or wind intensity to offer reports on the state of the hanging section. Impact. In January of this year, it was reported that 75% of the project had been completed, but in recent months we have seen how they have advanced so much that it is practically only missing and installing the security elements. The idea is to open at some point in June this year and, once open, will allow Crossing the canyon in just a couple of minutes when before it was something for more than an hour. But beyond all this, the most impressive thing is that they have been able to build an infrastructure in a very complicated place and condense 439,000 m³ of concrete and 49,000 tons of steel in just four years. And the cost? In theory, 280 million dollars that are difficult to estimate whether they will recover by joining rural areas, but as infrastructure and demonstration of strength, the Huajiang Grand Canyon bridge is imposing. And will remove the record from the highest bridge Lege’s, also in China.

We knew that the olive trees were very old trees. What we did not imagine is that they arrived at 4,000 years of age

by

The olive tree is undoubtedly one of the most iconic trees in the Mediterranean basin. The olive groves have populated the fields of southern Europe and the Levante since time immemorial, but such is the longevity of this species that the history of some of these trees also goes back, at least to antiquity. An example of this is the Vauves olivelocated on the Greek island of Crete. Conservative estimates throw this tree about 2,000 years. This would imply that in his life he could be a mute witness of events such as the division of the Roman Empire, the fall of Biscay and the Ottoman Empire and, of course, the birth of contemporary Greece. Broader estimates calculate that this tree could reach 4,000 years of age. This would not only do it contemporary of figures such as Pythagoras, Aristotle or Alexander the Great but also implied that this plant was born in the Crete Minoica and it was Witness of the collapse of the late bronze ageone of the most intriguing events that occurred at the dawn of history as and how we understand it. But perhaps the most surprising detail of all this is that the olive tree of Vouves continues to bear fruit. This has led many to wonder, how is it possible? What makes this specimen already its species in general so long? The olive tree (Olea Europea) has a life expectancy that, although it does not become ancient, does exceed several centuries. It is estimated that the life expectancy of the trees of this species Round the five centuriesalthough there is some debate about it. In this sense, A study published in 2021 In the magazine Dendrochronologyestimated that the majority of “monumental olive trees” had maximum ages that ranged between 300 and 500 years. Estimating the age of an olive tree is difficult. We indicated at the beginning that the estimates of the age of this millenary tree ranged between 2,000 and 4,000 years, a very wide fork precisely because of the difficulty that involves calculating the age of these trees. Dendrocronology is based on using the growth rings of tree trunks to estimate their age: how many rings, so many years. Counting rings in a carved copy is simple, but doing it in a living tree and doing it in an olive tree is already another song. The trunks of the olive trees grow irregularly, which implies a seemingly chaotic pattern in the rings inside, making the count especially difficult as pointed out A study published in 2013 In the magazine Plos One. His curious growth could be related to his longevity. According to Scott Travers, Biologist at Rutgers University, In an article for Forbesone of the “Secrets” behind longevity of these trees is in vegetative or clonal reproduction. That is, in the fact that this tree consists of various cuttings that start from the same root. This, adds Travers, allows this type of plants to survive extreme conditions, including similar fires, cuts and incidents. Another of the tricks for survival, Continue explaining traversIt is in the biochemistry of the tree, which offers mechanisms that allow repairing damaged tissues, as well as defending against pathogenic organisms. The same oil that humans take advantage of by the tree that gives us through its fruits. The elders of our environment Spain also has ancient olive trees, although we do want to find a tree that competes in age with the olive tree of vouves, we have to go to Portugal. It would be an olive tree located in Abrantesin the center of Portugal. According to a study conducted by the University of Trás-Montes and Alto Douro (Utad), Mouchão It would be the tree that would have this record with an age that would be around 3,350 years. Spain also has ancient olive trees and among all of them stands out The Arión Fargaa tree that we can find in the province of Tarragona. The estimated age of this olive tree is more than 1,700 years. This implies that this millenary tree would have been planted at the time of Emperor Constantine I. Olives are not the only millenary tree species in our environment. Cedros, Secuoyas and even Dragos Canarios can also reach ages that would pale the biblical matusalem. The olive trees are trees with a long life expectancy but do not usually fill the lists of the longest trees on the planet. The two longest -known non -cloned trees are two pines called Prometheus and Matusalemto which ages are estimated above 4,000 years. Both belong (or belonged in the case of Prometheus) to the species Pinus Longaevathe “long -lived pine” so it is not completely surprising this fact. When Prometheus was cut, the botanists who analyzed him told more than 4,800 rings, so he was estimated at an age of about 4,900 years. Estimates indicate that Matusalem has also surpassed for decades The 4800 -year -old brand. If we include clonal organisms we can find older trees. For example, the Pando forestconsidered the largest living organism on the planet, composed of thousands of cuttings of the same clonic tree, could have close to 80,000 years old According to some estimates.

Many countries already have more mothers between 30 and 39 years than between 20 and 29. With all that implies

On September 5, 2019, a woman named Mangayamma Yaramati went down in history: she had been the mother of twins. The key fact is that I was 73 years old at that time And it was possibly the oldest woman who had given birth. It is an extreme case, but the truth is that the world has been embarked for years in a situation in which every time Less births occurand increasingly. And these graphics that we can consult in Our World in Data They reflect that reality that is not encouraging. 2012. The tabarra was given a lot with what the world would end in 2012, but what really happened is A change of trend in births: It was when they began to give more births between mothers from 30 to 39 years and when births between mothers aged 20 to 29 years began to fall. Worldwide, this is significant because there is a good part of the world (especially developing countries) in which the weight of births falls to those women aged 20 to 29, with alarming birth figures between girls from 10 to 19 years. It is those countries that make up a world photo that shows that The birth engine is gripped. Spain. Let’s focus on Spain for a moment. Although we walk to the record of inhabitants with more than 49 million, this has little to do with more children. In fact, it is thanks to immigration, since The tables Births and vegetative balance show a very unfavorable situation for Spanish demography. And the data is devastating: more children are born of 41 -year -old women than 25. The change in global trend occurred in 2012, but in Spain we advance a little. If we put the magnifying glass in 2008, we can see the curve between the two age periods we were talking about, increasingly distancing themselves and adding Another age strip to the equation: Women between 40 and 49 years. In recent years it has stabilized in the three stripes, but in 2008 60.1% of children were born in the strip of 30 to 39 years, 32.6 in the strip of 20 to 29 years and 4.3% in the 40 to 49 years. In 2023, the figures had changed a lot: 63.3%, 24.8%and 10.2%, respectively. The neighbors are not much better. The European panorama is very similar. If we discriminating between the different countries, we see that the data and curves are very similar to those that we can find in the case of Spain, but if we group Europe, we can see two very clear inflection points. One in 2014, at which time births by girls from 10 to 19 years decreased and crossed those who occurred in women from 40 to 49 years, who have continued to increase in recent years. Another, in 2015, when exactly the same happens, but between the descending strip of 20 to 29 years and the ascendant, in a meteorically, segment of births between women aged 30 to 39. Stable latam, but eye. On the other side of the puddle, in Latin American territory, the situation is very different. It is more aligned with what we see in the world graph, with a strip of births predominant among women aged 20 to 29, but where we can already appreciate a clear increase in births between women aged 30 to 39. Then, of course, it depends on each country. Mexico is very aligned with that territorial graph, but in Argentinafor a few years the lines of 20-29 years and 30-39 years are approaching dangerously. In Chili There are more mothers from 30 to 39 years and in Colombia The good news is that birth between 10-19 years is falling. The Asian drama. And the European situation is not encouraging for the generational relay, but if we go to Asia, the graphics are devastating. It is a case of those of “It is better an image than a thousand words”, and then we leave the graphics of China, Japan and the most devastating: South Korea. China is the one that “saves”, but the two stripes of critical age are getting closer. The government is applying measures of all kinds: Looking for Women by Door, lower the legal age to marry either Finance painless birthsall in order to increase the birth rate. In Japan they are also Applying measures Not only to foster birth, but to attract foreigners who can work in different positions throughout the country. And South Korea is in a demographic winter from which it will be difficult for him to come out. In the end, it is something that depends a lot on each country, but there are more and more arrows that suggest that, most people They don’t want to have children. Within this, there are economic and conviction reasons that we will see if they are passengers or have come to stay. At the moment, in Europe the demography goes to the idle and the countries that go best … They are still a disaster.

50 years ago we discovered people whose blood did not fit into conventional types. We have just discovered why

by

We have been classifying blood types for more than a century as a function of two characteristics, the antigens of these and the RH factor. The four types of blood depending on the antigens (0, A, B, AB) and the two depending on the RH (positive or negative) allow us to classify people’s blood into one of eight categories. But as always, there are exceptions and one had intrigued scientists since the 1970s. Until now. A new blood group. A study led by researchers from the University of Bristol a new blood group has describedANWJ (positive or negative). According to the study, the key to this group is in the evil gear, a gene that encodes a homonymous protein that we can find on the surface of the red blood cells. A more complex system than it seems. The antigens surrounding the cell wall of the red blood cells are a pillar of blood transfusions. The presence of antibodies linked to this type of molecules makes some transfusions associated with complications. For example, a person from Group A receives a transfusion of a person from group B, antibodies associated with antigens to attack newly arrived cells. There are two key systems, AOB and RH Factorwhich are key since they are the ones that present the most diversity, and therefore greater is the possibility that a blood transplant can generate incompatibilities. However to date we have found more than a quarantine Of variants that, although they affect a small part of the population, must be considered. 50 years of mystery. The ANWJ antigen was discovered in 1972 but it has not been until now that we have discovered the genetic background behind the existence of Anwj-negative people, that is, people whose cells do not contain this antigen on its surface. This absence affects less than 0.1% of humanity and is generally due to hematological and oncoligic disorders. The evil gear. The team responsible for the discovery investigated the few known cases of ANWJ-negative people who were not as a result of any disorder. They found that this antigen was in the bad protein. They found that the hostj-negative people lacked full copies of the protein badly. “The work was difficult because genetic cases are very scarce. We would not have achieved this without the sequencing of exams, since the gene we identify was not an obvious candidate and it is little that we know of the bad protein in the red blood cells,” explained in a press release Louise Tilley, co -author of the study. The details of the study were published In an article In the magazine Blood. Less risks in transfusions. Knowing the different blood groups, including those that only include a very small portion of the planet’s inhabitants is important. The more we know about these groups, the greater our ability to Avoid complications associated with blood transfusions. “Now it is possible Nicole Thornton addedalso member of the work responsible for the work.
