This Barcelona bus has been working with a fuel that we all produce: our excrements

by

A bus of line V3 has been circulating through the streets of Barcelona that has been operating exclusively with a renewable fuel generated from what we least imagine: human waste. And best of all, the experiment has been considered a success. A project that has managed to evolve. This project was baptized as’Nimbus‘, and is the result of a collaboration agreement between The local water management company VeoliaMetropolitan Transport of Barcelona (TMB) and the Autonomous University of Barcelona (UAB). Together they have turned the concept of circular economy into something very tangible: transform the sludge of wastewater into biomethane for public transport. Five years later, and with good results in the hand, the project is ready to move on to the next level and start with large -scale production thanks to European funds. The ultimate goal is to make the production of this fuel based on the solid waste of the city to end in the deposits of the buses themselves in the future that is not very distant. This creates this fuel. The heart of this innovation It is found in the purification of Baix Llobregatone of the largest in Europe. Every day, this plant processes about 400,000 cubic meters of wastewater. While 95% of the water is regenerated for agricultural or urban uses, the remaining solid waste, known as sludge, usually end as dry material for agriculture. The Nimbus project has given it a new purpose. Using an innovative process, researchers have managed to transform four cubic meters of mud per hour into high purity biomethane. This gas is pure enough to be used in vehicles with natural gas engines without any modification. The secret is to refine the initial biogas. Initially, gas contains 65% methane and 35% carbon dioxide. Instead of separating gases, Veolia’s team Combine carbon dioxide with hydrogen that is obtained in renewable sources. In this way, almost all the biomás becomes biomethane, making the resulting fuel emit so much carbon dioxide. A fuel responsible with the environment. The figures that result from this first phase have shown that this biomethane works very well. It emits 80% less carbon dioxide than traditional natural gas and complies with strict regulations of EU euro VI emissionsalthough it produces nitrogen oxide to very small amounts. An alternative to electric buses. Right now, Barcelona’s periphery routes need a bus that has a high passenger capacity and greater autonomy. This is something that electric buses cannot offer today, but biomethane, maintaining the reduction in the emission of carbon dioxide. The future: more buses and production at an industrial scale. After five years of success, the Nimbus experiment gave way to a new phase: the project Sempre-Bio. The objective is now climbing production, going from generating biomethane for a bus line to do it for two. For this they have a budget of more than eleven million dollars, with financing from the European Union. As detailed in the project, with this budget they will “reduce the investment and exploitation costs of biomethane production plants and expand the biomethane production potential through new routes of waste valorization.” Many projects to find the ideal fuel. Synthetic fuel It is one of the great research results for finding an alternative to natural oil. One of the examples is The e-diéselwhich is based on “water and air” for conventional engines, or even Toyota He already works with hydrogen to turn it into an alternative To keep the combustion engine. But the reality is that right now combustion cars are in danger of extinction. Electric cars They don’t stop growingand the Chinese market Not stop driving this sector on other continents Like Europe.

The last extreme idea in beer fermentation has nothing to do with alcohol. It has to do with murderous bees

by

The human being has been fermenting beer since time. In spite of this there is always a place for innovation and, probably the “recipe” created by microbiologists from the University of Cardiff, in Wales, is not precedent in the history of mankind. Bee-r. A team of researchers He has created beer using a type of yeast found in the so -called “Killer Bees of Namibia.” The yeast in question (Saccharomyces cerevisiae) It was extracted from specimens of this bee that had died due to natural causes, and then used for the fermentation process from which beer is created. The origin of the idea was on the visit of the British team to the University of Namibia. During the trip, they explain from the Unviersidad de Cardiff, the team was interested in these bees. “When we arrive back to Cardiff, we use the isolated yeast from the murderous bees, next to yeast extracted from Welsh bees, to create several beer remittances,” Les Baillie points outProfessor of Microbiology at the Welsh Center. The “murderous bees”. The so -called “murderous bees” are also known by the least threatening name of Africanized holiferous bees. It is a hybrid subspecies of the common bee (Apis Mellifera), which results from the hybridization of other subspecies of this common insect. The Denomination of Killer is due to aggressiveness Of these bees with whom they consider a threat: these bees attack in large numbers which increases the risk of encounters that are fatal. What do you know? The yeast S. Cerevisiae is (as its name suggests) a yeast commonly used In the manufacture of beer so, regardless of the singular of its origin, beer would not be special. However, we will not have to contrast that fact by our own means. This beer, They explain its creatorsseeks to combine the knowledge of the equipment in microbiology to bring it to products related to bees “to produce something unique.” Now, it’s time to climb the process, looking for some winery willing to take this “recipe” to the market. This could also serve to economically promote this type of research. “Our killer beer is a complementary project for our Pharmabees study. Our study is showing how honey, wax and other bees products can play a role in solving some of the greatest world challenges, including resistance to antibiotics and superbacteria” Baillie added. Pharmabees. Within the Pharmabees project, various actions focused on exploring, for example, how the pollination of certain plants can help us in the fight against superbacteria are registered. To do this, the team installed various hives in the university environment, accompanied by specific plants that, in principle, could lead to bees to create new types of honey and other products. The idea highlights the importance of these insects, not only because of their role in ecosystems but also because of their potential capacity to help synthesize certain compounds. Compounds that, who knows, could one day use for the most surprising purposes.

An app to go to strangers ceremonies

by

Two men suited sneak into a wedding. No one knows them, but there they are: providing with champagne, laughing with the guests and looking to flirt on the dance floor. It is one of the first scenes of Wedding wedding, The comedy starring Owen Wilson and Vince Vaughn in which the unthinkable played in play: infiltrate others. What looked like an absurd fantasy today begins to happen really. In France, it is no longer necessary to invent excuses or disguise yourself as a distant cousin: it is enough to download an application, pay entrance and sit at the wedding of complete strangers. This has come Invitin. The app that converts love into an entrance ticket. Created this year by the entrepreneur Katia Lekarski, exmodel and founder of Digital Platforms of Child Design, Invitin functions as a Wedding Airbnb. Couples publish their celebration, set the price per person and those interested buy their seat. The company stays with a 15%commission. As explained to The Guardianthe idea arose when their five -year -old daughter asked him why they never invited them to weddings. “I thought: what if you could pay the entrance to a wedding just like you pay a guided tour or dinner with strangers?” He said. Anyone enters. As they detail on your websitethe bride and groom can review the profiles of the attendees and they must sign a code of conduct: arrive punctual, dress elegant, not to drink in excess and not publish photos without authorization. The concept is not entirely new. In India, the company Join My Wedding It already connects foreign tourists with local couples who celebrate traditional links, under the motto: “You have not been in India until you have attended an Indian wedding“. There, attending a ceremony can cost about $ 250 per person and is sold as a cultural experience. Invitin takes that logic, but adapts it to the European context: it is not about offering folklore to visitors, but that French couples finance part of their wedding by making it a shared event. The first wedding with unknown payment. The pioneers were Jennifer, 48 -year -old actress, and Paulo, exatleta, 50, who married this August in a country house near Paris. With an 18 -month -old son and after getting to get to an appointment app, they decided to try Invitin after discovering it at a bridal fair. Its history, Collection by The Guardianhe has detailed that they sold five tickets to 130 euros each, who joined their 80 family and friends. The new “payment guests” enjoyed the whole day: votes in the garden, cocktail with live music, formal dinner (with vegetarian option, since the bride does not eat meat) and the posterior party. How much is intimacy? According to Jennifer, money is almost secondary. “It helps to cover decoration or dress, but we do it because we are outgoing and we think it could be fun to share. In addition, we have many more single friends than single men, so this helps to balance things a bit,” Daily Mail explained. Buyers – or guests – also live it as an opportunity. Laurène, 29, He has confessed to The Guardian that I saw it as “a way of living a different wedding and traditions” in a happy atmosphere. However, the model is not exempt from controversy. In Daily Mailsome readers described the practice of “shabby”, remembering that the word “guest” loses all its meaning if it implies paying. In fact, they remember a case of a New York couple who asked for $ 333 per person to friends and family to marry the Cathedral of San Patricio. The outcome was with 80% of the guests refusing to attend. Lekarski defends, however, that it is a cultural and experiential phenomenon, not just financial. Figaro Gather couples testimonies They see it as an opportunity to replace absent guests, expand the list without shooting costs or even creating new friends. A Russian user has summarized it thus: “Attending French weddings will allow me to better understand their traditions and culture.” The transformation to the show. The phenomenon does not arise from nothing. In the last decade, weddings have become Macro events. As my partner has pointed out in Xatakathere is an authentic “fever” for watching weddings in social networks, with videos that accumulate millions of views in Tiktok and Instagram. The bride and groom are looking for viral moments: theatrical entries, fireworks, rehearsed choreographies. At the same time, the costs shoot. In Spain a link can cost what an average worker earns in a whole year. The tendency to fatten the invoice includes eccentric ideas: Tattooists in the Convitevirtual reality cabins, thematic photocalls. Even controversial restrictions are imposed, as “without alcohol” weddings For fashion Healthyto despair of the guests. In that context, Invitin is almost a logical consequence: if weddings are already lived as a show and are unassumable for many couples, why not turn them into an event shared with payment tickets? From the Airbnb sofa to the altar. Today the app adds only hundreds of users and a few confirmed links, but its founder already dreams of expanding to the US and European tourism. And it would not be strange if he did it: after all, we have already normalized sleeping in the bed of a stranger with Airbnb or dinner at someone’s house we don’t know through Eatwith. Logic is the same: transform the intimate in payment experience. First was hospitality, then the family table and now the wedding. Invitin does not invent anything, simply pushes a border more: if we rent the living room and bed, why not also the “yes, I want”? The question is if we will see weddings in Spain soon with payment entry, in a country where the links are especially expensive and the banquet is almost sacred. Because, for now, Invitin is a French experiment, but its incentives – a budget and convert an intimate rite into show – are universal. Epilogue. In Wedding weddingthe protagonists … Read more

Those who make poop on the planes

by

We live surrounded by bacteria. Many are inside us And nothing happens, although there is others that are more treacherous. Above all, there are superbacteria. They are the ones who have Developed resistance to antibiotics And they are extremely difficult to eradicate. The World Health Organization itself has cataloged them as one of the greatest health threats, but there is something that can help us end them. Make peanut on the plane. AMR. They are the acronym in English of “Antimicrobial resistance”, Something that was found when antibiotics began more common in the 50s and that has accelerated in recent years. Excessive use And sometimes, inadequate of these medicationsas well as The sale without recipehas made bacteria rise level and be more resistant. And the worst part is that they are not located, but that they travel all over the world due to the trade of animals, food and the trips we can do by plane. Air pollution also helps transport resistant bacteria. Impact. The most common pathogens are Staphylococcus aureus, E. coli, Klebsiella pneumoniae, Acinetobacter Baumannii or multirresistant tuberculosis, and it is estimated that they currently produce more than one million direct deaths every year. For A population of more than 8,000 million peopleit may not seem too much, but already You talk of about 39 million direct annual deaths for 2050 due to these superbacteria. They put transplants at risk, they are a threat to food security, make treatments difficult and hospital stays increase. And, in addition to direct deaths, It is expected An increase in health costs of about 160,000 million dollars annually. The analysis. We have commented that traveling by plane makes it easier for these resistant microorganisms to move from place, being able to contaminate totally new groups. It is something we have seen with Pandemics like Covid-19and that migration of superbacteria by plane has been the protagonist in a study Prepared by the National Science Agency of Australia, in collaboration with the University of Xiamen, the University of Australia del Sur and the Technological University of Michigan. Specifically, they analyzed wastewater from the bathrooms of 44 international flights that arrived in Australia from nine countries: 18 came from India. 14 of the United Kingdom. Six from Germany. The rest were a flight from: France, United Arab Emirates, Türkiye, South Africa, Japan and Indonesia. Aircraft excrement extraction system Differences. The researchers detected nine priority and superbacteria pathogens, some of them resistant to multiple drugs. Of the nine, five were in the fecal waters of the 44 flights, while a gene that confers resistance to last resort antibiotics was detected in 17 flight. This is the most resistant to the most powerful antibiotic treatments. Nicholas Ashbolt, a microbiologist at the University of Australia del Sur, commented that “flights from Asia, in particular from India, showed higher concentrations of genes of genes from Antibiotic resistance Compared to flights from Europe and the United Kingdom. ”Yawen Liu, a researcher at the University of Xianmen, ensures that these differences can reflect variations in the use of antibiotics, water health, population density and public health policies of each region. Peanut. Now, why is it so important to urinate or defecate on a plane to fight the superbacteria? Warish Ahmed, the main scientist of the University of Australia, comments that “the wastewater of the aircraft captures microbial signatures of passengers from different continents, offering a non -invasive and profitable form of monitoring threats such as AMR’s.” In addition, in the study they have not limited themselves to measuring the presence of superbacteria in the wastewater of the airplanes, but to find out If the disinfectants used in the bathrooms affect AMR. The results showed that nucleic acids remained stable up to 24 hours, even in the presence of strong disinfectants. This points to the importance of analysis of the depositions in the aircraft for surveillance purposes. Critical. “Wastewater monitoring of aircraft could complement existing public health systems, providing early alerts on the emerging threat of superbacteria,” says Ashbolt, and the study concludes by pointing out that this mere proof of concept has great potential in the real world to convert the bathrooms of the aircraft into an early warning system that allows to better manage the better public health. I recognize that I have made a multitude of flights and, whenever I have been able, I have avoided using the toilet of the plane because it seems uncomfortable. But, if I have no choice, in my next flight I will lite my blanket and I will do my things thinking that I am doing a favor to science.

Labubu Humanity Bags are being small. So its creator already knows how to sell even more

by

Labubu have become a global phenomenon. In China alone, for 2024, they reached sales for about 355 million euros and, since then, their figures in the rest of the world They grow at a rhythm of 480%. To Spain too The fever arrived: The stores They ran out of stock and many buyers have had to resort to Wallapop or Vind, with the consequent Risk of falsifications. Pop Mart, the manufacturer of the stuffed animals, He has shot in the stock market After affirming the CEO Wang NO that its initial forecast of reaching 2.8 billion dollars in sales for this year can grow 50% to 3,580 million, something that, says “would be quite easy.” He would be able to double the income of 2024. And they have explained how they plan to do it: launching the “Mini Labubu“ From the bag to the mobile. With their rabbit ears and a very sinister smile, the labubu have conquered bags and backpacks of their buyers, after being popularized by influencers like Lisa, from the K-Pop Blackpink groupDua Lipa, Madonna, David Beckham or Kim Kardashian. Now Pop Mart wants to conquer something much more common and transversal than a bag: the smartphone. As the company explained, the Mini Labubu can be placed on phones, and will not take them to launch them. It will happen this week. The ‘Sonny Angel’ taught the way. The mobile accessories market is huge, but none explains so well the step that is going to give Pop Mart with the Mini Labubu like the ”Sonny Angel‘, those little “plastic angels” that after being created in 2004, are now glued to many mobile and even laptops of very young people from Spain after being a viral phenomenon in Tiktok. The key was the version ‘Hipper‘, designed to fit with the mobile and corners and frames of the screens and popularized by celebrities such as Rosaría or Victoria Beckham. And they took steps such as collaborating with covers of covers such as Casetify that show Pop Mart where sales can continue to grow once they launch the reduced size labubu. In fact, They already collaborate With brands such as Disney, DC, Marvel, Minions, Capcom, Garfield, etc. As explained in The Economist, China is now “Cool”and has everything to conquer Europe. Without supplying, but with a plan. Wang said that it is very optimistic for the company’s performance “in foreign markets”, and believes that “there is a very wide space for growth”, predicting that the sales of North America and Pacific Asia will match those of China in 2024. The problem is that Labubus’s production does not give to meet demand. This explains average resale prices of $ 121 (and up to 240 euros), compared to the 30 dollars that are officially sold. It is the same problem that Xiaomi also faces in China with The resale of su7but they are working on expanding the production capacity, and Yuan Junjie, president of the Pop Supply Chain Center Mart, states that produce 10 times more than in the same period last yearwhich translates into 30 million units per month. They plan to continue improving, with two new factories abroad and two in China. At the moment they have benefited from Getting with Labubus is an art.

There was a day that Volkswagen wanted to have “the Bentley of the town.” It went wrong

by

If something has shown us the history of the car is that it is completely irrational, extremely competitive and very conservative. The electric car is demonstrating it clearly. The number of brands has triggered and China wants to make a foothold on European soil. The reality is that Only Tesla seems to have found the way Correct and China is moving in Europe … but with Combustion engines. That conservatism is not new. Raising a brand from scratch is only possible with a huge economic effortsustained and almost blind for years and years (like Tesla)with the help of state media (as Xiaomi and its association with one of the national Chinese car companies). But it is also almost impossible to change the perception that the client has of you. Winning to the client and ascending on the ranks of the market can take decades. A good example is Hyundai and Kia that have some of the best -selling cars In our country but they had to start earning market share selling cars much cheaper than those of the competition. But rapid movements, those who want to position a brand in a higher segment almost from nowhere or those that seek to compete with premium brands with a model that equals features but also in price is generally a call to failure. There is a good handful of examples and the Volkswagen Phaeton is undoubtedly one of the most representative. History of a failure Luckily for those who like cars and unfortunately from manufacturers, the purchase of a car is irrational. It has an inevitable part of aesthetic taste but also for quality perception, affinity with the brand and construction of an image and a history based on the past. That makes, for example, Renault fails with Vel satisf either Avantime Although they were very good vehicles that tried position yourself above the generalists. Nor has Stellantis (and before PSA) achieved return to DS to your luxury past Despite the multiple attempts. And something similar happened to Volkswagen Phaeton. By order of Ferdinand Piëch, then president of the Volkswagen Group, the Germans wanted to assault the premium market with a Berlina that was called “The Bentley of the People”. The intention was to stick with the Mercedes S, BMW 7 series and, curiously for being part of the group, with the Audi A8. The bet was so strong that the possibility to match (or improve) in equipment and materials to its rivals with a more adjusted price was not even tan. It was directly to resemble all fronts (also in price) and in the executives of Volkswagen they took a tortazo. In fact, the Volkswagen Phaeton Not even was a version of Audi A8. Yes, he shared some aluminum panels with the Berlina of the four hoops, as explained in Km77 In the early 2000s, but for development it departed from a blank sheet and even The Volkswagen Dresde factory was builtknown for their Glass structure and for being the one that, discontinued the Phaeton, covers the complete electrical models of the company. In that assault on the heavens, the Phaeton was sold above 66,000 euros for what the German triad looked from you. A Audi A8 It was sold at that time slightly below 69,000 euros. A BMW 7 series It started from 67,500 euros. He Mercedes S Yes it was significantly more expensive, starting from more than 71,000 euros. In those early years of the new century, all German luxury Berlins shared two things: they all had versions above 120,000 euros. And they all had gigantic engines. And the Volkswagen Phaeton was not going to be less. Its most “small” engine was already a V6 in diesel and gasoline versions. From there, it could only be dreaming. Volkswagen’s bet was also sold with a V8 4.2 gasoline, the famous V10 5.0 TDI and an endless W12 6.0 of gasoline that was sold with 420 and 450 hp versions. The average consumption of the latter was around (with the homologations of that time) 14.5 liters/100 km on average. And of equipment, the Phaeton was not badly served: heating seats, electric with memory and massage, bi-xenon headlights, four-zone heshlyzizer, indoor in the skin topped with wood and the possibility of replacing the rear seats with two sidewalks to improve comfort. Developing the car, therefore, was not going to be easy. At least this is attesting to 1,100 million euros that, according to Autoweekthe Germans invested in their development. From Automotive NewsHowever, they raise the figure to 2,000 million euros. But despite the expensive development and the good of the product, selling the Phaeton was not simple either. To the point that, according to this last medium, the Germans lost 28,101 euros for each unit sold. Keep in mind that the company had made a effort huge in machinery, employees and a new factory (The Dresden crystal plant) To launch a car that would meet the quality of a vehicle of its price range. It is said that Ferdinand Piëch delivered a series of unnegotiable requirements to put the car on the street among which was the ability to maintain the interior temperature at 22ºC circulating in a sustained way at 300 km/h with an exterior temperature of 50ºC. And all despite the car was limited to 250 km/h. Only for overestimating the capabilities of the car and that there was no open door to the client’s disappointment. But the market did not respond despite the fact that Volkswagen reached up to 100 patents during its development. Estimates that aimed at 20,000 units sold a year were impossible to meet. Even as the years passed. Because during the decade and a half that the car was on sale only 84,253 units were sold. Volkswagen’s most optimistic forecasts, collect in DiariomotorThey could exceed 35,000 units sold. And, as exceed, the 50,000 cars sold. Seeing one of those people’s bentley was not as complicated as seeing a true Bentley but of course it … Read more

Why the airlines continue to force us to put the airplane mode in 2025

by

“Please be sure to put your electronic devices in airplane mode Before takeoff. If your device does not have a plane mode, bring it completely during the flight. ” Something similar to this message is reproduced thousands of times every day in the world and, although not everyone pays attention, a usual gesture when sitting on the plane is to connect the plane mode. 25 years after birth The plane mode, although the message continues to reproduce, it is no longer mandatory to put the mobile in plane mode. However, there are pilots who continue to defend their use for a reason: their comfort. It made sense. The airplane mode was born as a result of a concern: the possible electromagnetic interference that electronic devices could cause in both communication and navigation systems in airplanes. It was a possibility, like the one that existed of light fourth to gasoline in gas stationsbut the chances of a catastrophic failure They were very low. However, to mitigate any potential risk and guarantee safety, the measure of prohibiting the use of electronic devices during certain phases of the flight was adopted. Fiction has contributed to still thinking that something can go wrong, such as the moment of ‘The Simpsons‘In which Bart is playing with a Game boythe hostess asks him to turn it off and, in doing so, the plane begins to plumn). As these devices advanced and added more networks, Wi-Fi, Bluetooth and more powerful connections, the “plane mode” was adopted that disable these transmissions. And, as the main motivation of this function was its use in commercial flights, the name and icon of the plane was consolidated although its use was recommended in other environments such as hospitals or the aforementioned gas stations. 2014 and 5G. After implanted and turned into A standard for several devicesin 2014 things began to change. In September, the European agency EASA He gave the passengers free to use their electronic devices without plane mode. That most lax attitude left the ball on the roof of the airlines, which could maintain or not the mandatory use of the airplane mode and, in fact, many have adopted internal Wi-Fi systems that allow them to earn more money. One of the famous Extras of the companies. Asterisk. While the plane is not going to fall, the use of this way is still promoted for a very specific reason: the crew comfort and controllers. These years, in well -known blogs such as’Ask The Pilotor like Some pilots commentAviation experts have appeared that comment that the way to prevent an annoying buzzing for communications is recommended. And it is logical. As Comment The pilot Rafa San Julián, from Iberia, the aircraft teams are “much more protected than formerly and are much less vulnerable.” Now, the plane mode is still recommended for a very specific reason: technology and Power of mobile networks It advances every few years and “it cannot be predicted if these interference will occur with the new equipment. Therefore, as a safety measure, it is requested that the mobiles put in plane mode so that they do not emit with the same power with which they would issue without that mode,” he says. Concern by the way 5g. And block with what Boeing detected a few years ago. FAA, which is the US aviation agency, He issued Directives warning about possible 5G signal interference in band C (3.7 to 3.98 GHz in the US) Be too close of the frequency used by the radio heights of Boeing and Airbus aircraft (4.2 to 4.4 GHz). These radio altimeters are essential in landing maneuvers and in other systems such as soil proximity notice. The concern would affect airplanes such as Boeing 737, 747, 777 and 787, and would force pilots to perform landing maneuvers in safe and more manual mode. However, no serious accidents or incidents have been reported due to this interference and, if They have canceled or delayed flightsit was due to an increase in caution. In fact, FAA itself command Shortly after a message of tranquility. That distance of 0.22 GHz It is enough As if there are no interference, but at that time it was not more caught. Fly calm. Therefore, not remove the plane mode during a flight will not make the plane fall, but it can generate a buzz or White noise In communications, being annoying for pilots and controllers. Activate it is a good idea to save battery and so that if you are going through a country without roaming and remotely get coverage, do not charge you five euros for downloading a WhatsApp message.

A century of herbivores at ease was ending with Yellowstone. Salvation was logical: call the wolf

by

‘Jurassic Park‘He has memorable moments, but perhaps a phrase is the one that fell me the most in his day: “Life makes its way”The problem is that the hand of man exercises Too much influence on natureand the Yellowstone park It is an excellent example of how an ecosystem that was regulated perfectly was twisting due to a decision made 100 years ago: eradicate the wolves. Consequence? May the park run out of trees. And to turn to the tortilla, the researchers had an idea: return to repopble Yellowstone with wolves. Yellowstone in short. The arrival of European settlers to the North American west caused the expansion of the agriculture and, above all, livestock (With grazing and the Basques carrying the reins). The enemy of cattle was the wolf, since it was a direct threat and, due to its vital role for the local economy, extermination campaigns began to be carried out. The result was that, by 1930, the wolves (as well as other predators such as pumas, coyotes and bears) practically disappeared from some areas such as Yellowstone. Even the army is implied. If the predators disappear, those that were their prey have free field to reproduce without control, and that caused that alces and deer proliferate, creating a huge imbalance in the population of herbivores and, therefore, in the flora of the park. In the end, overparation and a overpopulation of wild herbivores caused the trees to disappear from Yellowstone. Lobos, to curra. The trees that worried were the scenes and it is not a matter of the alces to stay without food. How can we read in Oregon State UniversityThey are vital elements for birds that nest in them and for beavers, among other species. Thus, in 1995 the decision of V was madeOlver to incorporate those predators to the ecosystem. Lobos, Bears and Pumas, another predator practically removed from the area, returned to the place they should never abandon, and the results have not taken to appear. Results. Luke Painter, professor of ecology and conservation at the Faculty of Agricultural Sciences of the University of Oregon, comments that “The reintroduction of great carnivores has started a recovery process that had been paralyzed for decades. ” studyThey detail that the “price” is the sustained decrease in population of the Cervus canadensisallowing the quarrels to experience exceptional growth. This “trophic waterfall” examined 87 rhods of poplars in northern Yellowstone, finding that 43% of them presented a new population of small trees between five and ten centimeters in diameter, being the first positive count since the 1940s. They comment that the density of grazing remains the dominant factor for the regeneration of poplar, but that that Introduction of predators has relieved the load that herbivores exert in the ecosystem. In addition, the study rules out changes in the climate as the main cause of that recovery, once again influencing the importance of the reintroduction of the wolf as the element that has caused “changes in the distribution of the ALCE, giving rise to recovery”. The Wolf as a lever. Not everyone is on that ship. A previous study On the part of researchers at Utah State University and the University of Wisconsin Stevens Point put on the table that, although the role of the wolf had been important for the recovery of poplar, its role was exaggerated due to the way in which previous measurements were made. But what has happened in Yellowstone is not an isolated story. That persecution of the wolf has been lived in other areas and, in Europe, due to its impact on livestock, they are also promulgated laws for extermination. The ecological consequences are similar to the views in Yellowstone and, in Scotland, there is an overpopulation of red deer that are ending local forests. At a time when we need trees so that They catch co₂it is already being raised release more than 150 wolves in the ‘Highlands’ Scottish to control deer and save forests. While some release them… But as we are condemned to repeat the story, at the end of 2024, the Permanent Committee of the Bern agreement voted in favor of reduce wolf protection status. This makes it “strictly protected” to “protected”, which opens the door to A desire on the part of certain parliamentariansfarmers and hunters: that can bother the wolf. And not with paint ballsas in Netherlands. In Xataka | Russia has found a frozen wolf 44,000 years ago “in perfect condition.” First decision: open it

A United Kingdom restaurant makes history with its first water letter. Free tap water also serves

If we look for the definition of a sommelier, the RAE It presents us with the following: “Wine expert and liquors who, in large hotels, restaurants, etc., suggests customers the appropriate drink for the occasion.” Do not go to the SAR: Wikipedia It says the same. We understand by sommelier, or Sommelier, an expert in pairing who knows which wine fits better with different dishes. Amazon even has a ‘telesumillers’ servicebut there may soon be a new meaning for Sommelier: Water expert. In 2011 the Water sommelier uniona professional and international association that was born in Germany and that appeared with a single purpose: to promote the professional, training and economic interests of water sommeliers to defend the culture of mineral water. It is not the only one that exists, since there is also the Doemens Academy In Germany or the Fine Water Academy In the United States, as well as some associations in countries such as Italy or China. And, in the same way that there is a wine letter in some restaurants, the objective of these water experts is that there are unique premises for a very specific reason. A select water letter. Wine letter … and waters Doemens is very clear that “Not all waters are the same”And, apart from giving training in German, English and Mandarin, in 2024 they began to form Sumillers in Spanish. Describe The task of the sommelier of water such as “disseminating and providing knowledge about the quality, characteristics, variety of brands and the value of excellent mineral waters.” Although it is a minority, in the international panorama, profiles such as Martin Riese, the first ‘Sommelier’ Certificate of the United States, but also the British Doran Binder begin to flour. Binder, with a very active profile in Instagramwhere he has more than 55,000 followers, he is a sommelier who supplied the water of his brand -crag spring water- to the British restaurant The Popote. It is a French -style restaurant that is in the Micheli GuideNY in which they have a letter with about 140 varieties of wine. At some point a few years ago, and as they expose in CNNBinder approached the owners of the Popote to propose something: a menu of water. At first, they thought “It was a ridiculous idea”but they changed their minds when they attended a water tasting. Of that “ridiculous idea”, the owners went to “the water is not just water.” The tasting was similar to what is done with beer or wine. First, they tested about six varieties, but then made a second tasting with the same waters, but accompanied by food such as Manchego cheese, comte, chocolate, olives or parma ham. That’s when they realized that the taste “changed” and that they appreciated that certain waters married better with certain foods. Convinced, they let Binder devise the menu, becoming the first in the United Kingdom to have a Water letter which offers its product (five pounds per bottle) up to 19 pounds, about 25 euros, for The Palace of Lifego, a gas with gas from Portugal. There are also Spanish, Italian and French waters. Binder with your water letter Ok, very good, but … what are you selling me? According to Binder, the water key is TDS, or dissolved total solitos. In the statements to CNN, “the measure of minerals is what determines the flavor and taste. The destined water has a zero TDS.”It is fantastic for cleaning windows and for the carbut lousy for humans, ”he said. The range it offers in the restaurant goes from the 14 TDS of the mineral water with Lauretana gas to the 3,300 of Vichy Celastins. The Vichy Catalan, which is another product that is usually seen in waters, It has about 2,900 TDS. At the opposite, sea would be between 30,000 and 40,000 TDS. From Spain we have ’22’ that is soft in the mouth, with a delicate profile And it is, as with wine, to extol the taste of everything. If the French water they serve is “quite salty, you have to combine it with something that is saved, like a parma ham, and both are balanced. So, the water no longer knows salty and what remains is a more durable flavor of the ham in the mouth,” says Joseph Rawlins, owner of the Popote. Eye, they also have tap water as courtesy. I imagine that it will be equivalent to Ask for a torrefact in a specialty cafeteria. Apart from this, in a context in which Alcohol consumption is decreasinghaving “gurmet” options of without alcohol is something that makes all the meaning. How to serve the water In the end, it is what is sought when you seek to exalize flavors mixing elements that seem not to stick, such as salt chocolate, for example. If we want to do this at home, there are tricks. Joanna Vallejo It is a wine sommelier that has also specialized in the water and has offered some tips To enjoy at home a better experience when enjoying water and rest of food: Read the label to find the origin. If you drink wine, accompany the glass of a glass of quality with gas, since that acidity point will make the flavors of the wine are enhanced. Use correct water. For example, for spicy or acids, use gas with gas. For softer foods such as salads or fish, waters with less minerals. And for more forceful meat or food, water with a higher mineral profile. Do not put ice in the glass because what you will do will be the same thing that happens with coffee: to await and mix a high profile water with another that is from the tap (no matter how good some are). And the most important thing about this (because, like me, you have raised an eyebrow thinking that now you will have to wear a monocle every time you are hot and drink a glass of water): Joanna herself comments that It … Read more

more repentance, more erased clinics and professionals who live worse than before

The tattoo has gone from be a symbol of rebellion to A fashion accessory. Soccer players, Influencers And even your fifth neighbor look like skin designs. This massive acceptance caused an unprecedented boomFilling Spain with studies and artists. But the party is over. The bubble seems to have exploded and has left behind a precariousness and also repentance panorama among the different clients who decide to remove their tattoos. Regretting what they tattoo. A phenomenon that we are seeing right now is that of Delete what one day was permanent in their skins. This was demonstrated by a study Made by Lutronic PBSwhich pointed out that 60% of the people who tattoo in our country end up regretting. The problem that arises is that eliminating a tattoo is not easy to do. The ink that is injected directly into the skin dermis, which is the second layer of the skin. This causes an aggressive treatment to be able to eliminate it completely. The number of professionals who remove them increase. The demand for withdrawing tattoos makes new treatments and clinics appear. In 2023 it was recorded A 30% increase in the number of demands regarding eliminating tattoos through laser technique. And is that choosing a good professional It is fundamental so that later it is marked on the skin. And such is the ‘fashion’ of eliminating tattoos, which even in social networks can already see how trends and up as #Tattoremoval where The before and after this treatment is shown. And sometimes people make these tattoos impulsively Without having anything clear. And then the repentance is there. The tattoo sector has a ‘dark side’. In addition to the change of opinion of many consumers of this art, The avant -garde has collected in a report As the market has changed radically. Raúl, a professional tattoo artist since 2001, reports that when he started in this world, the coil machine was an almost artisanal artifact of more than 300 euros. Now this same machine It can be found on Amazon for fifty euros With an initiation kit that includes needles and inks of doubtful quality. This technological democratization has had an immediate effect: a marketing of the market. The National Union of Professional Tattooators and Anillers (UNTAP) esteem That in Spain there are about 10,000 “legal” tattoors, but they estimate that the double works irregularly from their homes. These “home tattoors” They are announced on Instagram and Facebookcompeting directly with studies paid for rent, taxes and health licenses. And this is something that results in a fall in demand to professionals. The ‘Glovo’ model has reached the tattoo. If unfair competition is a battle front, labor conditions are the other. The sector operates in a legal limbo where the ‘false autonomous’ has gained prominence, as they relate to the avant -garde. In this way, they point out that the studies have autonomous tattoors, who carry a percentage of the final price of each tattoo, and the material costs are shared. The point is that some studies would demand to meet fixed schedules of up to 60 hours per week and with imposed vacations. Emilio San Miguel, labor lawyer, is clear about it: as soon as an autonomous depends economically on a single payer and has time and tax holidays, it can be considered a false autonomous. “Almost all the tattooists who work in studies,” he says. ‘Chiquitatus’ and businessmen: the devaluation of art. This panorama has been the breeding ground for a new business model. According to Fidel Prieto, secretary of UNTAP, many of the new studies are not led by artists, but by investors who see tattoo as a simple business opportunity. In this way, they take care of a place with a central location and hire young tattooists, with little experience and more likely to accept abusive conditions. And to be a large production chain, they specialize in ‘Chiquitatu’, that is, a butterfly, an infinity or a small symbol that has a cost of 50 euros. Something that denounces devalues ​​the price of this work, and makes people have to work from their home and in black so that it deserves the penalty economically. Because becoming autonomous is something that many people cannot afford. What you earn in the trade is not very attractive. As they point out in the report, a tattoo artist can have a good month and invoice about 3,000 euros gross. But It is not a stable tradeand depends on the number of customers you have. In this way, in a bad month those income can collapse up to 700 euros easily. A tattoo artist, Virordia, points to that I would prefer to have a decent salary, a normal schedule and decent conditions. The situation is as unsustainable that figures such as the “false hired” have emerged: a 10 -hour weekly contract for someone who works more than 45. The objective is to reduce the social security quota, a desperate patch in a broken system. Tattoos have a future beyond the aesthetic. Although many people are tattooed for pleasure, science explores other options. For example, it is already explored to use them as a system to control blood glucose or go much further to Be authentic biosensors to analyze other biochemical parameters of our organisms in a little invasive way.
