The north of Spain has been complaining about mass tourism for years. Asturias has discovered the bitter consequences of losing it

by

The formula of nature, calm and good kitchen that for years promoted Rural tourism In Asturias It seems to lose bellows. AND clearly. Although the photo of recent years is distorted by COVID, the housing of the principality specialized in this type of tourism have seen how His activity descended until they were driving before the pandemic. At least according to INE data. It is not so much a “puncture” in the flow of travelers and in that of the rooms (They last less) and the loss of interest in the national market. The phenomenon is interesting because it coincides with another or even more media: complaints in a large part of the peninsular northern ( Galicia to Cantabria or in your own Asturias) For precisely the opposite, the effects of tourist massification. While in Cantabria they cry for not being “The North Ibiza” And Galicia complains about The “fodechinchos”inside and the Asturian mountain the hoteliers cry out for measures that avoid the slow decline of rural tourism. An icon in low hours. A quick search arrives on Google to verify that rural tourism does not go through its best moment in Asturias. TO The news of the Regional Press about The fall of activity those in the sector claiming are added “Specific aids” and those of the Principality trying to reassure him. In fact, in January Adrián Barbón He promised to “rethink” rural tourism of the region “to recover thrust.” Shortly after its executive announced a Bond program With discounts designed to encourage demand. That the situation of the sector arouses so much interest in the Principality is more than understandable. In the mid -80s, and thanks largely to your campaign “Asturias Paraíso Natural”the community managed to make a place in a sector in which until then the tourism of Sun and beach prevailed. Today Asturias adds hundreds of establishments with thousands of places (in August the INE computed almost 1,400 and 14,800respectively) and stands out for its volume of rural houses per capita. What do the data say? That the sector has known better times. The INE shows that last year the Rural Accommodations of Asturias received some 304,000 travelers who paid for 924,400 overnight stays. The first data is not exactly bad. It is a slight increase of 1.7% compared to 2023 and is online of 2019. The second worries. In a Growth scenario The number of hired nights fell 3.2% year -on -year and remains away from the almost 975,000 overnight stays that the sector managed in 2019. The 2025 start has not been especially good. During the first quarter the volume of travelers and overnight stays fell with respect to last year, although the data should be handled cautiously. First because in 2024 Holy Week, a period of strong tourist demand, fell in March and this year did so in April. Second because There may be variations important from one month to another. In fact the Principality He has checked already for the growth of February. “Very black winter”. The truth is that the sector is far from satisfied. Recently the president of the EO-Porcia association implied in An interview with eldiario.es that the balance has been of everything but good in recent months. “50% of the peoples that are still inhabited today are for rural tourism. Fixed population and allows you I recognized. In its own accommodations, three apartments and a house, it did not register any reserve between the Bridge of the Constitution and last Holy Week. Looking for the causes. The big question is … What are you due to these data from the sector, especially overnight stays? Why if in August 2001 the average stay In rural accommodations, was 6.13 days passed to 4.76 in 2019 and 4.24 last year? For Ana Llanoof the Fuentes del Narcea Association, one of the keys is the change in demand. Tourists are looking for different things today during their vacations. Or rather, it does so at a different rhythm and way. “Before people came to spend the summer, to spend a few days in nature, to enjoy the house themselves. Now people want regrets In eldiario.es. His comment is in tune with the data on the duration of the rooms and another key indicator: the overnight stays fall in the rural one, but grow in the set of Asturias. “They end rural tourism”. To that challenge others are added: the de -stationalization, the need to enrich the offer with packages or the competition of other types of accommodation, such as Tourist housing (VUT) or the “illegal establishments” that (precisely by acting outside the administration) also blur the balance of the sector. There are those who speak of tens only between Vegadeo and Navia and who focuses the focus on the VUT. “They are ending rural tourism,” they said recently From the sector to The voice. Foreign lifeguard. The general photo leaves another interesting nuance. Asturian rural accommodations may be invoiced today less overnight than before pandemic, but that fall is mainly due to domestic demand. The nights hired by Spaniards fall, but those reserved by tourists from outside the country have grown considerably. With that backdrop last autumn the Principality launched A campaign aimed above all to the Asturian themselves. His slogan: “Are you sure you know Asturias?” When tourism does not arrive. The case of Asturias is interesting for something else. Between record tourism data and with the open debate on the effect of the sector on the real estate market, over the last years in much of Spain they have happened The protests against tourist. Especially in points such as the Canary Islands or Balearic Islands, but also in areas of the North, including Galicia or Cantabria, where the saturation of certain points has become a matter of debate. The Asturian rural and interior situation leaves a key question: what happens when tourism stops arriving or comes less? What if the Fodechinchos Do they stop traveling or areas that have developed … Read more

We have discovered that cutting the consumption of an amino acid is related to more life expectancy. In mice, yes

by

Virtually anything, in excess, can end up being harmful. Water is no exception and amino acids, the “bricks of life” are not. This was demonstrated by a study conducted from one of those compounds. In moderation. In study, conducted in mice, noticed that cutting the intake of isoleucine in the diet of animals helped increase the life expectancy of rodents by 33%. Isoleucine. Isoleucine is one of the essential amino acids. Amino acids are essential molecules for life as they represent The links from which proteins are created. We know thousands of proteins, all of them composed from about twenty amino acids. Our body can synthesize more than half of the amino acids that it requires to create proteins, but nine of these amino acids, the so -called essential, we must obtain them from our food. This is the case of isoleucine, an amino acid that we can find in a diversity of foods such as eggs, soybeans, meat and fish. A previous track. The study started from a Previous indication. A study conducted ten years ago in the state of Wisconsin observed that the diets of people with obesity were richer in this amino acid than the average population. In mice. For Study this correlationthe team went to the laboratory and studied its effect on mice. Laboratory animals divided into three groups: one control, to which no food restrictions were applied, another whose diet was altered to reduce the presence of amino acids, and another whose diet was normal in the presence of amino acids except in Isoleucine. The amount of isoleucine that this group received was ⅔ less than the standard. The mice were six months when they started these diets, which would be equivalent to an age of 30 years in humans. Analziating results. The team observed that the two groups of mice with amino acid restiring lost body fat at the beginning but those who had all the restricted amino acids lost it again soon. More important, the team observed that mice in this diet with less isoleucine increased their life expectancy: 7% in females and 33% in males. Another relevant detail that they observed is that the mice in this diet would ingest more calories. Possibly, they point out, to compensate for the lack of nutritional contribution of this component. Despite this, they also burned more of these calories, which led them to maintain a lower body mass than the rest of the study mice. The details of the study were published In an article In the magazine Cell metabolism. And what about humans? The team responsible for the study was likely that the restriction of this amino acid can have a similar effect on humans. For now that possibility is little more than speculative but the fact that the greatest presence of this amino acid in the diets of people with obesity is already observed implies another indication of the existence of some relationship. Beyond the biological differences between one species, the human diet is much less controllable than that of laboratory mice. The field of nutrition is extremely complex, with an infinity of nutrients, some of which interact with each other. He effect of other factors As our physical activity or tobacco consumption also affect our health and our life expectancy, making it difficult to elucidate the net impact of a nutrient on the human body.

In Jerusalem they have just discovered a 2,000 -year -old garden that coincides with a description of the Bible: the tomb of Jesus

by

If we stick to the literature of that best-seller In religious code which was (and is) the Bible, the Evangelical story of the Gospel of John on the burial of Jesus had resonated with a singular symbolic force for centuries. Namely: the death of the “Messiah” occurred in a “Calaveras Place” and the funeral in “A new, fertile garden, without prior use”, almost like an echo of Eden. Ironies of life, a reform in Jerusalem has found an extremely similar place. The garden under stone. Although literaryly powerful, that passage has always lacked the same as many other passages: topographic precision. However, recent excavations in the Church of the Holy Sepulcherled by a team of archaeologists from La Sapienza University of Rome, have unearthed indications that could confer that fragment biblical an unexpected empirical support. Taking advantage of some renovations initiated in 2019 after decades of disputes between the religious communities that administer the temple (the orthodox, the Franciscans and the Armenians), the team of Professor Francesca Romana Stasolla began, in 2022, a meticulous work under the nineteenth -century panel of the sanctuary. There, under slabs and centuries of liturgy, they discovered the vestiges of An old quarry Of the Iron Age that, in Jesus, already served as a place of burials excavated in the rock. From the Empire to faith. This space, although it was not the only one of its kind in the Jerusalem of the time, was the one that the first Christians identified as the place of the crucifixion and the grave of the Nazarene, conviction that led the Emperor Constantine (after his conversion to Christianity) to order the construction of the first temple on that soil loaded with memory. The current church, rebuilt by the crusaders in the twelfth century, is the last incarnation of that ancient veneration. The revealing of the current finding is that, in the period between the exploitation of the quarry and the erection of the temple, the area was transformed into An agricultural space. The finding. Archaeologists identified low stone walls and stuffed land for cultivation, as well as evidence of olive trees and vines 2,000 years ago. For Stasolla and his team, these discoveries offer a possible material correspondence with the mention of the garden that appears in the Gospel of John, which suggests that whoever wrote, or compiled that story, possessed a intimate knowledge of the geography and territorial organization of the city at that time. Faith culture. Beyond the symbolic force of the garden and its potential link with the story of the burial of Christ, the findings also include Ceramic coins and fragments of the fourth century, which suggests continuous use of the place even before its formal Christianization. Although Stasolla herself speaks cautiously with respect to proclaiming any definitive confirmation of the place of Jesus’ burial, the researcher does underline that the true value of the discovery lies in showing how entire generations They have projected their faith On that site. The history of Holy Sepulcherhe insists, it is not only the story of a character or a religion, but an integral part of the history of Jerusalem. The continuity of the cult, the transformations of the environment and the weight of tradition have conferred that space A living identity which transcends archaeological certainties. Seen thus, between fragments of agricultural walls, millenary roots and sacred land, the recent finding not only excava in history, but also in the religious conscience of the West.

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.

We have just discovered that 20% of our DNA comes from an unknown hominid population: population B

by

Perhaps at this point on remembering that human evolution is more like the branched structure of trees than to the linear image that we often use to illustrate it, that image in which our ancestors are irrigating and pertrechating tools. However, the bifurcations of these tree branches fail to illustrate some evolutionary changes. Because sometimes species not only diverge, they also converge. A recent genetic study has detected The trail in the human DNA of an old population that separated from our main lineage approximately 1.5 million years ago to converge some time later. The study has estimated that the genetic legacy of this second population (or population b) represents approximately 20% of our DNA today. The study responsible for the study also raises the possibility that this legacy has been positive for our species. According to the hypothesis raised, these genes would have been contributed to improve our cognitive capacity. “The question about where we come is one of those that has fascinated humans for centuries,” explained in a press release Trevor Cousins, co -author of the study. “For a long time, it had been assumed that we evolved from An ancestral continuous lineagebut the exact details of our origins are uncertain. “ The separation of these two evolutionary branches would have given rise to an evolution in parallel of the Populations A and B. The evolution of the population to correspond approximately what we already know, although the new work allows us to know in more detail its evolutionary history. As explained by the team responsible for the study, after the separation of the two populations, the population A would have suffered a “Bottleneck”: While the population B prospered, the A had to cross a period in which its numbers were very scarce, a situation that also implied a drastic reduction in genetic diversity. From the population A would have emerged the main human species of the past, including not only our species but also the “bifurcation” that would give rise to the arrival of Neanderthals and Denisovanosanother human species (or subspecies) that would have inhabited Central Asia hundreds of thousands of years ago. Reunion between species The history of population B is still enigmatic. The study has not recorded events such as population bottlenecks. We know that the core of this population disappeared but that at some point their roads crossed with the population A, giving rise to genetic exchange. He “Reunion” between populations It would have given more than one million years after separation, about 300,000 years ago, according to the estimates of the study responsible for the study. After this reunion, population B would fade without leaving another trace. The genetic inheritance that each population would have left in modern humans would be unequal. While we should about 80% From our genetic material, to population B we could owe the remaining 20%. The study detected that these genes of population B would concentrate sections of the population’s own genes A. Scheme that represents the evolution of the two populations and their relationship with Neanderthals, Denisovanos and ‘Homo Sapiens’ contemporaries. Cousins, Aylwyn Scally & Richard Durbin (2025). This suggests, explains the team, that both populations would have been little compatible. The uncompatibilities would have been purified over the years through the process known as purification selection, a process in which natural selection is eliminating harmful mutations. On this legacy, the team also indicates that these are genes closely linked to the functioning of the brain and the Information processing. This could imply that this small genetic inheritance could have had a great impact on the evolution of human intelligence and in the Evolution of our species. The analysis focused on the study of contemporary humans and not on the bone remains of prehistoric populations. The team resorted to the 1000 Genomes Project initiative, thanks to which it had a large genetic database with information about inhabitants of Africa, Asia, Europe, and the Americas. The details of the study were published In an article In the magazine Nature Genetics. The history of evolutionary convergence is long. Perhaps the best known case is that of the Neanderthals (Homo Neanderthalensis). This already extinct species occupied Europe and Asia tens of thousands of years before our species left Africa but, once they found themselves They coexisted in various areas of Eurasia. Thanks to its genetic legacy (which varies according to populations but usually around 1% or 2% among non -Afro -descendant), we know that the coexistence of sapiens and Neanderthals gave a lot of: The union of these species engendered hybrids whose lineages ended up merging with those who gave rise to contemporary humanity.

In 2019 we discovered some fungi capable of metabolizing gold. There are already those who want to make it the key to space mining

by

The story Start more than five years ago In Boddington, south of the Australian city of Perth. Over there, Between murderous animals and gold mines, a team of researchers from the Australian Csiro discovered something truly rare: that certain fungus strains Fusarium oxysporum Not only could they extract gold from its surroundings and integrate it into their structure, but in doing so they managed to spread faster than the rest. It seemed a curiosity without more, but in recent years the situation has begun to change. But, a moment, why is something so “weird”? Good question. After all, we know of good ink that fungi “play an essential role in degradation and recycling of all types of organic material (Like leaves or bark), but also in the cycle of certain metals such as aluminum, iron, manganese and calcium. “Why would it be different with gold? Because, as Tsing Bohu explained, a researcher in charge of the project, “Gold is so inactive (chemically speaking) that this type of interactions is unusual and surprising, he had to see him to believe it.” And he saw it. In fact, lo published in Nature Communications. It was the first solid evidence that fungi could have a relevant role in the gold cycle in the earth’s crust. The “mushroom” of golden eggs. Quickly the mining industry put his eyes on the investigation. Especially right there, in Australia. The continent island is the second largest gold producer in the world, but The consensus among analysts It is that without new deposits the production was going to fall (and much) in a short time. Initially, the industry thought that CSIRO’s investigation could serve to locate these new deposits. As we explained years agoin Australia it is relatively common to do prospects in forests of the Aucaliptos family or near termites because they have a close relationship with the precious metal. Why not analyze the land in search of those strains of Fusarium oxysporum? But there is one more possibility. As Eduardo Bazo explained to Eugenio Fernández In a very interesting interviewin recent years there have appeared companies that work on what we could call “Metabolic mining“That is, in using organisms to extract gold. “And what do you want that?” You could ask. “Isn’t it easier to identify where gold is and extract with industrial methods?” Yes, here on earth, yes. But these companies look a little further: in space mining. For years we have talked about the existence of huge mineral deposits in the solar system and, for almost the same, We have fantasized to be able to exploit them. The problem is that, Beyond the current technological limitationsS, to the danger of normal mining, is added the fact that we talk about processing metal in space. But and if we use ‘metabolic mining’? The idea of ​​sending modified strains of these fungi (or other microorganisms) that They will process the mineral for useverything would become easier. I don’t know if more viable, but simpler. It is much less rare than it seems (this type of approaches we use to innumerable products that we usually use), however to take it to the world of mining seems a little more complex by pure efficiency. However, that’s ‘now’. While I write (and while The era of cheap materials ends) Several research groups They are cultivating all kinds of microorganisms with the idea of ​​being able to grow gold sooner rather than later.

Coffee has no cholesterol but does raise its levels. And someone has discovered the perfect elaboration to limit it

by

We are increasingly clear that coffee is a food with Positive properties for our health. However, it has traditionally been surrounded by many myths. Many of them Caffeine relatedbut also some related to things as serious as supposed damage to the heart and its incidence in cholesterol levels. And the latter is half myth. Because coffee has no cholesterol, but compounds that, depending on how we prepare it, will influence more or less on LDL (“bad cholesterol”). Cafestol and Kahweol. Let’s see, if coffee has no cholesterol, how do some of its compounds do have an impact on cholesterol? The reason is that we do not drink coffee in grain, but we crush it to get a ‘dust’ from which to get an extraction and, therefore, the coffee cup. When we break down the coffee beans the oils of it are released, and in them we have fat -soluble diterpenes that are those that have an impact on blood cholesterol levels. Mixed effects. These compounds have some health benefits, since they have anti -inflammatory and anticancer properties. It has also been observed that it favors osteoblastic activity that helps bone health and can have antidiabetic effects. However, the contradictions are there. Although both have a similar effect, it is cafestol that acts as an enemy of FXR receptors, inhibiting the synthesis of bile acids in the liver and, therefore, reducing its effectiveness by eliminating the cholesterol from our body. When this occurs, cholesterol levels increase, with more notable increases in LDL cholesterol. The investigation. Does this mean that I must stop drinking coffee? Not much less, since although these diterpenes can influence cholesterol levels, lead It allows to maintain the cholesterol at bay. We are not talking about sugary drinks or alcohol, go. Now, in a investigation carried out by the University of Uppsala in collaboration with the Technological University of Chalmers have found the coffee preparation method that less Cafestol and Kahweol allows our body to reach. Processing. To do this, the team took two coffee samples from different offices resting machine machines every two or three weeks, with coffee varieties that included average and dark gall of five trademarks of ground coffee. Most machines use ground coffee, but a couple They grind before (the super -automatic). In total, eleven machines were analyzed, three that use coffee concentrate (mix with water). Compared the results with other preparation methods such as percolation, the French press, boiled coffee and samples of espresso. The goal is to see which one prepares coffee with the highest levels of both coffee and kahweol. And the result is overwhelming. Boiled coffee. In the upper graph we can see the concentration of coffee in the different elaborations and there is a clear winner, as well as an obvious “loser”. Previously, it had indicated that boiled coffee was the highest source of these diterpenes and was not as recommended on a regular basis. And it is logical because it does not filter coffee at all. On the contrary, the best elaboration to reduce coffee to the minimum possible is through filter coffee. Here there are variations depending on the filter material, but in the analyzes it is shown as the elaboration that, in a more consistent way, keeps the coffee levels in coffee. Interestingly, we can achieve the same effect by preparing boiled coffee if we like it more and then filtering it, which is the icon of the chart sock. Too many variables. A problem that researchers were found is that, although the concentrations of diterpenes in the machine of the machines was always inferior to the preparations of boiled coffee and other elaborations such as French pressthe concentrations vary significantly between machines and between the sampling intervals. Of the machines, those that use liquid concentrated coffee have lower levels of diterpenes, similar to those of the filtered coffee. Typologies. This may be due to the type of coffee that is placed in the machine or the temperature at which they heat the water, but there is a more disconcerting case: that of the espresso. The researchers comment that a “considerable and clear explanation variation is observed in the concentration of diterpenes among the four samples analyzed”, recognizing that it is something that requires an additional study because it could be relevant to the usual consumers of this preparation. “It can contain high levels of substances that raise cholesterol.” It is the warning of this machine in a Swedish office photographed by Uppsala University And limitations. The team has focused on measuring the concentration of diterpenes, ensuring that it is known that they negatively affect other lipoproteins such as triglycerides, but that it is an aspect that they have not taken into account for their research. In addition, they also recognize that, although the results are solid and there is a “better way to prepare coffee” to maximize coffee, the study has important limitations. On the one hand, the size of the sample, since these are several collection maintained over time, yes, but of eleven concrete machines when there are many, many more in the market. On the other hand, there are variables such as water pressure and temperature, contact time between ground coffee and hot water, grinding or grain gall. Next steps. Come on, too many things, something logical taking into account that there are not only many different coffee machines, but a huge fan in terms of water and coffee gut. It is something that, they point out, it would be interesting to analyze in the future, as well as studies that compare coffee consumers of companies with coffee machines in front of others in which they use paper filtered with paper. In whatever, there are many studies and they themselves comment that “long -term prospective studies on cardiovascular results that could help confirm the causality of the associations” must be carried out between the diterpenes and the increase in LDL cholesterol. At the moment, I will continue to have coffee regularly, but … Read more

Millions of people drink from the water that arrives from the snow of the K2. We have just discovered pollutants in them

by

The K2 is the second highest peak on the planet after Everest and probably one of the most difficult and dangerous peaks to reach for climbers. It owes its name to the Karakórum mountain range, where it is located. It is located in a remote puppy area played between Pakistan and India, but its remoteness has not prevented pollution from reaching it. And with it the risk of thaw. Black carbon. A study by an international team of researchers has found black carbon traces in the Godwin-Austen glacier and on the surface of the K2. According to Explain the study responsible for the studythis pollutant can be an ice risk in a mountainous area that feeds a river responsible for supplying more than one billion people. Black carbon is presented as small carbon particles as a result of the incomplete combustion of some compounds. These particles are part of the volatile compounds known as particular matter and can affect our health and the environment. As explained by the team responsible for the study, being deposited in snow or on ice, black carbon can accelerate its melting. This may imply the loss of frozen mass, reducing the time that snow passes on the surface, they add. Taking samples. In its study, the team collected samples of superficial snow in fields 1 and 2 of the K2 between 2018 and 2019. Sampling was also carried out along the walls of two well -excavated wells in the snow layer on the glacier. The team performed an isotopic analysis of the snow layer to estimate when the snow began to accumulate. All this for, In the words of Nicolás González-SantacruzCo -author of the study, “Determining the moment of formation of the snow layer is essential to precisely interpret black carbon data.” The details of the work done were published In an article In the magazine Journal of glaciology. A seasonal snow. The analysis concluded that the snow of the glacier has a seasonal character, that is, that it accumulates between October and until the end of winter and then disappear completely between spring and summer. This fact allowed to know in detail when the different concentrations of black carbon were deposited. Looking for the source of pollution. The team analyzed the black carbon samples also to track the origin of this pollutant. They found that the accumulated carbon during the fall of 2018 had their main origin in the North Basin of the Indo River, while in the subsequent concentrations (winter 2018 and 2019), the influence of regions such as the Middle East, Asia Central and Eastern Europe, González-Santacruz added. The sum of several problems. We associate the thaw of glaciers and other icy areas of the world to climate change derived from high atmospheric concentrations of greenhouse gases. However, neither thaw is the only phenomenon attributable to this change nor global warming has to be the sole responsible for the thaw. Understanding the diversity of factors that are interconnected in the context of climate change is key to understanding the potential effects of this, both in terms of people and in what affects ecosystems.

Mrbeast has discovered a much more lucrative business than making videos on YouTube: Sell chocolate

by

Mrbeast became a Internet superstar globally Thanks to his video and challenges on YouTube. However, far from beating content creation, the youtuber has managed to transform its fame into A business empire diversified valued in billions of dollars. Ironically, the main engine of this empire is no longer the more than 377 million Mrbeast followers and its most crazy challenges: selling chocolate has been much more profitable. The teenager who became a millionaire playing. Jimmy Donaldson, the name behind Mrbeast, began his adventure on YouTube in 2012 with only 11 years. Like most kids of his age, his first videos showed him playing fashion video games: Call of Duty and Minecraft. For years, he analyzed what type of content he worked better on the platform, learning the secrets of the algorithm and how to capture the audience’s attention. YouTube was small. He cannot be denied that he knew how to find the correct key and turned what began as a hobby, into a lucrative business that It led him to leave the university to devote yourself completely to your career on YouTube. In recent years, their videos have almost become blockbusters with hundreds of millions of visualizations worldwide, with challenges as popular as the recreation of “The squid game “in real lifetheir experiences of survival in extreme situations or Your own program In Amazon Prime Video. Diversify the business. However, despite the fact that the YouTube channel continues to be a pillar in the Holding of Beast Industries companies that Donaldson has created, it is not, from afar, the most profitable. The conglomerate of MRBASET companies has Lunchly under its umbrella, a brand of snacks, ViewStats, a software company for content creators. However, the real Crown jewel It is feastable, its chocolate bars brand. Feastable: nobody bites a sweet. Mrbeast’s incursion into the chocolate world began in 2021 with the launch of feastable. The brand became popular immediately because youtuber and their adventure companions usually consume them in their videos, and have even turned their chocolates into the protagonist of some of them. To promote their chocolates, Mrbeast challenged his followers to find a golden ticket on their chocolate bars, and invited the winners to compete for a boat of $ 500,000 in cash in one of their videos, to the purest Willy Wonka style. This strategy, combined with the quality of Your chocolate barscatapulted feastable to sales success. The chocolate empire surpasses the media empire. According to published Bloombergdocuments sent to possible investors, feastable registered sales valued at 250 million dollars last year, with benefits that exceeded 20 million. In contrast, the media business of MRBAST, which includes its YouTube channel and its reality show for Prime Video, generated a similar sales volume, but recorded losses close to 80 million dollars. “I lost dozens of millions of dollars in Beast Games,” Donaldson confessed a few days ago In the podcast The Diary of A CEO. The food business ate YouTube. These figures published in Bloomberg’s article reveal that The chocolate business Mrbeast is currently more profitable than what the YouTuber generates with its videos. In fact, Beast Industries forecasts suggest that feastable will triple its size in the next two years.

We have just discovered that food can also affect the risk of developing lung cancer

by

We know well that certain ways of life can affect our risk of suffering certain types of cancer. A clear case is that of the relationship between smoking and respiratory system tumors, especially lung. We also know that our diet It can affect to the probability that we develop cancers such as liver or colorectal. However, relationships can be somewhat more complex. Diet and lung cancer. A new study has linked The diet with the risk of lung cancer, a relationship that until now had remained, if it does not hide, at least in the shadow of other better known and explored connections. Adenocarcinoma and glycogen. The study focuses on the Pulmonary adenocarcinomaa tumor at the origin of 40% of cases of globally diagnosed lung cancer, explains the team responsible for the study. It is the cancer that causes more deaths in the United States, but it is also the most common lung cancer among people who have ever smoked. The new study focuses on glycogen accumulation. Glycogen is a polysaccharide, a sugar composed of simple sugars or monosaccharides, in this case a glucose chain. This sugar is used by our body as an energy reserve. The role of glycogen. The accumulations of Glycogen They had been observed in some types of cancers as well as in other diseases. Now, the team responsible for the new study, studied through computational and laboratory models how this complex sugar acts as “oncogenic metabolite.” As they explain, the greater the accumulation of the polysaccharide in cancer cells, greater and more dangerous will be tumor growth. In mice. The analysis in animal models (in mice) served to validate the theoretical results. The team found that, by feeding the mice with a diet that they catalog as “western”, capable of facilitating a greater presence of blood glycogen, cancer in the animals of the animals grew. In contrast, when glycogen levels fell, tumor growth was reduced. The details of the study were published In an article In the magazine Nature Metabolism. Diet and cancer risk. The team responsible for the study emphasizes that, although it is one of the first times (if not the first time) that lung cancer is linked to the diet, there are already numerous occasions when the diet has been put in the center of the strategies for cancer prevention. The diet is also an important pillar in treatments against this disease. “In the long term, our approach to cancer prevention should reflect the success of the antitabaco campaign (putting a greater emphasis on public awareness and policy -based strategies that promote healthier dietary choices as a fundamental component for disease prevention,” explained in a press release Ramon Sun, who led the team responsible for the study. Route for treatment. The good news is that the finding can open a way to improve treatments against this type of cancer. And we count at our disposal of drugs capable of controlling the level of glycogen in our body. Without the need to resort to pharmacological treatments, the study also allows highlighting the importance of a balanced diet in our health.
