Salmon sperm is the new fashion ingredient in aesthetics. And no, it’s not as crazy as it sounds

In the era of the cult of perfect skin, the aesthetic industry seems to know limits. Masks with bee venom, sera with snail drool, injections that They promise to reprogram Aging … Any compound that promises youth, elasticity or luminosity is a good formula for even Celebrities Be behind it, even if we are talking about salmon sperm. A new anti -aging elixir? Although talking about salmon sperm captures attention (and lifts eyebrows), the truth is that it does not imply directly applying reproductive cells on the skin. In statements collected by the Spanish, Dr. Araceli González, specialist in aesthetic medicine, has clarified: “This product is popularly because it allows you to obtain polynucleotides, components with great qualities to restore the skin without leaving any residue.” In this way, it helps support reparation, regeneration and collagen production on the skin. For celebrities it is not new. Personalities such as Jennifer Aniston had already undergone this type of treatments in previous years, as reported in an interview to the Wall Street Journal, where he even joked asking his estheticist: “Really? How do you get the salmon sperm?” However, what was previously a luxury curiosity, today has become a booming aesthetic trend that adds more and more followers, from dermatological clinics to Influencers In social networks. The Telva medium It has included it Among the seven major skin care trends by 2025. And the big question. How do you get? Well, the answer is more technical than biological. The PDRN is obtained by processing and purifying the DNA of the gonads (sexual organs) of the salmon. Sperm is not used as such, but the genetic material is broken in polynucleotide fragments, which are then integrated into sera, masks, injections or combinations with techniques such as microaguja or laser, according to He explained Dermatologist Mansha Sethi Thacker A Vry Well Health. A curiosity is that in Asia they usually inject it directly, while in the US they are applied topically after treatments such as exosomes or laser. Does it really work? Treatment defenders ensure that it offers visible and progressive benefits. According to Dr. Adam Friedman, a dermatologist at the George Washington University, for the same medium, it has detailed that it stimulates collagen production, improves hydration, accelerates cell regeneration and healing, and decreases inflammation and better pigmentation. For its part, the aestheticist Adeela Crown, Interviewed by the Financial Timeshe has summarized it thus: “It is a slower process, but bioestimulants such as polynucleotides make skin cells work to produce and maintain the basic components of healthy skin.” Its use in medicine. Although the boom is recent, seeing the benefits gives notes that it was already used before. As He explained Dr. Araceli González to El Español, The use of polynucleotides were already used in medical contexts to treat burns, serious injuries or even ulcers. In addition, preliminary investigations, mentioned by Varywell Health, They have indicated that they can have anti -inflammatory effects and have begun to use to stop hair loss and strengthen the scalp, with repeated treatments every few weeks. Are there side effects? Like any aesthetic treatment, it is not exempt from precautions. Dr. Richard Westreich, plastic surgeon in New York, has pointed out in The Guardian that side effects are generally mild: bruises, swelling or redness may appear, especially if the product is injected. In addition, as in every medical process there may be a risk of allergic reaction. For its part, dermatologist Emma Craythorne has warned in FT that “no current study is of high quality”, and although the results are promising, more robust clinical research is still required. A new aesthetic revolution? For many specialists, polynucleotides treatment represents a paradigm shift. Not only does it seek to correct visible signs of aging, but preserve and stimulate the natural functions of the skin. “It is a bioestimulator that does not change the volume or the shape of the face,” He explained Araceli González. Therefore, it is suitable for both young skins that seek to prevent mature skin with marked sagging signs or elastosis. In addition, it is beginning to be used in areas where other treatments do not work well, such as the lower eyelid, where botulinum toxin has no good results. Dr. Elizabeth Hawkes, an Oculoplasty specialist in London, has affirmed at ft that “polynucleotides have transformed their practice” for the security they offer in sensitive areas such as eye contour. What are the forecasts? What began as an eccentricity worthy of headlines, salmon sperm on the face, has evolved towards a trend backed by clinics, dermatologists and public figures. But between the promises of cell regeneration and the media brightness, is the question: are we facing a real scientific revolution or before another cosmetic seasonal phenomenon, camouflaged under a disruptive name? For now, science advances slower than social networks, but if something teaches us the history of beauty is that, in the search for eternal youth, no ingredient – unlikely that seems – is out of play.

China is attending a crazy race to demonstrate who has the safest battery. That’s why they crush them with tanks

If I point to the volume, I am not sure if I learned a lot or little in the university. But I am clear about one thing: I learned what was news or, at least, the criteria to point out whether an event is news. When the issues that can be discussed are put on a wording, different aspects are valued. Truthfulness, current, proximity … and novelty. And if an event comes out in the media it is because it is usually “unique, unpublished, unlikely or out of the ordinary.” I don’t say it, University institutions say. That is why it makes little sense to affirm that electric cars are dangerous based exclusively on news. We could do it if we had relevant studies that pointed out that the number of electric cars is notoriously higher than those of combustion. But it is not the case. We do know that the fire of an electric car is more complicated to turn off and more virulent. That is why it is logical that take action on ships where they are transported or working on New protocols in fire bodies. That does not mean that the risks of this technology are greater. In spite of everything, it also enters within a certain logic that when a fire is given or any other risk situation, the alarm voices are multiplied. From municipalities where They consider whether to continue buying electric cars a parking lots that prohibit their step. In that case, companies only have to show that their batteries are as safe as any other component of a car. As if I could pass them a tank over them. The crazy idea of ​​a tank Although it seems nonsense, it makes sense that manufacturers refine ideas when demonstrating the safety of electric car batteries. Keep in mind that, for example, In South Korea, an intense debate has been lived on whether or not these cars may accumulate in garages after A Mercedes Eqe will explode last year. When Byd arrived in Spain he had a challenge ahead. I needed to make themselves known and, above all, demonstrate that it was a company in which you could trust. We already know the prejudices towards the Chinese product. As a journalist, I don’t know how many times I could visualize This video in which a nail is going through an LFP battery without anything happening. It was one of the classic images. The other was the pressure tests. When too much pressure is applied to a battery (electric car or any other device) runs the risk of experimenting A thermal leak. Heat grows inside, chemistry is released and the pressure increases to cause an explosion with the consequent fire. To avoid this, the housings are designed to release the accumulated pressure inside, with the aim that if we have an accident, the pressure exerted on the battery does not cause an explosion. And the company can already tell us about figures and data and everything we want. But nothing better than the visual. Click on the image to go to the original tweet That is why Geely, explain in Carnewschina He has taken his new “Aegis Gold Brick Battery” a 36 -ton tank and has passed it over. And what happened? Nothing. Nothing at all. The battery did not give any sign of damage despite receiving 1.8 times the minimum pressure required by Chinese institutions to standardize a new battery. You can see the video on this link. They point out that the tank not only He crushed the battery On one occasion. He passed over it, returned on his steps and continued to crush her repeatedly. And did the same going over individual cells. The battery package “maintained its structural integrity without bulges, leaks, fires or explosions,” they emphasize. To overcome the test, the aegis Gold Brick Battery has been designed with a double wet coating that facilitates the dispersion of heat and thermal leaks since it is especially heat resistant to heat generated by aluminum oxide. It also has liquid-electrical separation of the materials. Photo | Geely In Xataka | Samsung has just revolutionized batteries for electric cars. In autonomy, in load time and in useful life

The Benidorm of North Korea is about to open. Your problem is how to fill the crazy number of rooms

In October 2024 confirmed the plan that had Pyonyang in hands. Benidorm is only one, but if tourism has become the Economic engine Of so many nations, they did not want to stay in the saga. Thus, North Korea announced that the ambitious project to turn Wonsan into a kind of Benidorm to the Korean There was a stern wind. The idea is now about to become a reality, it is called Wonsan-Kalma, and the number of rooms has gone hand in hand. An unparalleled resort. As we have gone countingKim Jong’s ambitious tourism project on the Kalma Peninsula, on the east coast of North Korea, seeks to position itself as one of the world’s greatest holiday complexes. A fact exposes the intentions: it has an estimated capacity between 7,000 and 20,000 rooms. Conceived as a tourist city from scratch, the resort Wonsan Kalma is described by analysts as the most huge tourism project ever driven by the regime. Announced Back in 2014the complex suffered multiple delays attributable to international sanctions and then at the closure of borders during the pandemic. However, its opening is already planned for June, and the regime has rehearsed a shy reopening to international tourism, although the economic viability of the resort remains deeply uncertain. Tourism as a strategy. Kim conceives the resort not only as a source of income in foreign currency, but as showcase of power and the modernity of your regime. However, the attractiveness of the enclave is in question: experts like Bruce W. Bennett and Marcus Noland They explained this week The doubts that foreign visitors attract in sufficient quantity to justify their huge investment. The logical basis of the project, which presumably aspired to capture South Korean tourists for its proximity and purchasing power, collides with the diplomatic impossibility of allowing them to enter. Meanwhile, and as We explain weeks agoRussian agencies have begun Offer tour packets for Citizens of Vladivostokbut even there the enthusiasm is doubtful. Russian travelers, According to the operators themselvesThey continue to prefer traditional destinations such as Thailand or Dubai. Oasis restricted to internal consumption. Thus, another plausible strategy of the regime would be to take advantage of the resort as an internal control and reward mechanism. They counted in Insider that the facilities could be used as an incentive for loyal citizens or exemplary workers, and the complex is designed with areas reserved for presidential delegations and suites. The problem? As Bennett points outaccess will be rigorously segregated, mainly to prevent North Korean citizens from entering foreign visitors. This structure reinforces the propaganda nature of the resort that, a priori, would serve more as a political showcase than as a real tourism center (something similar To “little manhattan” They raised recently). Structural limitations. Despite the monumental effort, the project drags many of the endemic problems of the regime. The Lack of experience North Korean in the hotel industry and the rigid state censorship are important obstacles to offer a credible tourist experience. In addition, recent history of the Ryugyong Hotel (That unfinished skyscraper for decades and symbol of North Korean failed excess) remains a latent warning. Plus: Kim’s fear of the free flow of information is incompatible with the logic of contemporary tourism. Therefore, although it is seen of modernity and luxury, it is likely to end up being Another monumental decorationwithout sufficient and useful tourists only as a propaganda tool. There is several examples similar A “diplomatic” letter. If you want, in parallel, the complex can be seen as a piece on the diplomatic board. In 2018, Trump had suggested Kim towill help your “big beaches” For economic development, and it is not ruled out that the resort is used precisely as a symbolic gesture in future negotiations, especially if Pyongyang seeks recognition as a nuclear power. Remember that the nation already has made “resort” For Russian soldiers. In that context, Kalma can always fluctuate, like promise or threat: It can be used to show openness or reinforce the cult of the leader. If so, Kim Jong Un, determined to differentiate himself from his predecessors, could see in “his Benidorm” not only a tourist destination, but a political statement to the world.

The second trailer of ‘GTA VI’ looks crazy, and is a sample of how good it feels to go against the industry

The wait until May 26, 2026 will be made long. In a strange ad, Rockstar confirmed a few days ago that the release date of ‘GTA VI‘It was delayed from an indefinite moment of this 2025 At the end of May next year. It is something that It has several readingsbut one of them was that they would soon launch a new trailer that, finally, would set the final launch date and, announcing the delay in advance, would cushion the blow. This has been. The company has just launched the Second Trailer of ‘Grand Theft Aut VI’ And … he is overwhelming. If the first launched in 2013 already allowed us to theorize whether it was something moving in real time or was a pre-control scene, this second trailer points to tour the same path. And the reason is that there are scenes of ‘GTA VI’ that are a real madness. ‘GTA VI’ will squeeze a decaffeinated generation First of all, I have to clarify that we can only judge the visual quality of the game with the means that we have available so far. To perform deeper analysis, we will have to waitat least, at the moment we have GamePlay scenes itself, but I think we can start making illusions with what Rockstar is cooking. For three reasons, in addition. The first is that, as I said, the first game of the game has already allowed experts to discuss its nature. Digital Foundry is a British media specialized in the visual and technical analysis of video games and They debated Long and lay on whether the trailer was in real time (that is, the engine of the game and scenes extracted from it) or a scene rendered beforehand. Some visual errors as Jaggies -S. Sierra- allowed the pixel counting, and the washed image of the edges points to the use of some type of tool such as FSR or DLSS. The second reason is that Rockstar is not Ubisoft and it is not a company that has accustomed us to CGI videos before the launch of the game itself or to Visual Downgrades. The third reason to believe that the game will end up seeing as in these trailers is that we have ‘Red Dead Redemption 2‘As an example. The 2018 title, without having received a patch for the current generation, continues to be better than many games of this generation, and that was designed to function in 2013 consoles. Come on, what There are hopes in ‘GTA VI’ at the visual level. And, as we say, we have reasons (and not only for these precedents). Trailer screenshot The new video begins very, very high, with some characters modeling that seem spectacular, very realistic animations both bodily and facial, without falling into the exaggeration of features, and all this bathed for what, I think, is the element that makes the trailer look as well as it looks. Because the textured seems very good to me, but the lighting that bathes each scene is to not believe it. Among all the moments, the one who has left me speechless is one at the beginning, when we see Jason returning in his car, at night, and observes a police detention. Trailer screenshot The flashes, The position of light spotlights And elements such as that good textured, the most realistic color palette than in the previous installment of the saga and gestures make me create that scene completely. But it is not the only one: Trailer screenshot Trailer screenshot Trailer screenshot I am somewhat tired of the term “photorealism” we have been abusing from the launch of the first ‘Modern Warfare’, but it really is the only term that occurs to me to describe what I am seeing. Then there are the characters, with a certain caricaturized and stereotyped touch, but the physicists of elements and hairstyles, Reflexes on surfaces (The interior of the car is amazing) or the vegetation play to make the scenes … surprising. Perfect? No, of course, and we see distant elements such as the sand or water that have visual artifacts, as well as some textures such as Lucia’s hair at some time that seem flat, but the general level is so, so high that, for the first time from ‘Alan Wake 2‘ and ‘Warhammer Space Marine II‘, I feel that this generation of consoles is worth something. And with more merit if possible in the Rockstar title, since it is an open world, with the complexity that this implies. Rockstar promotional image Rockstar promotional image Rockstar promotional image It may be making many illusions, but it comforts me that people in Rockstar think that the game is going to see like this. Not current workers, something impossible in one of the most hermetic studies in the environment, but veterans of the company. One is Ryan Fuechliffe, member of Rockstar from 2009 to 2021 and who commented that ‘GTA VI’ will offer a “revolutionary” realism. Mike York, who worked as an animator in the company, also commented That the game will probably go to 30 frames per second because Rockstar was focusing on visual quality. But, although I seemed to me … wild, you have to have your feet on the floor. Obbe Vermeij, former technical director of ‘GTA 3’ to ‘GTA IV’ He pointed out That, although the first trailer was “incredible”, the technical jump may not be as large as the one seen in ‘GTA V’ and that could disappoint some players. As I have already said, you have to wait to see Gameplay because, obviously, these two videos that Rockstar has revealed play a lot with the rules of the visual language of cinema. Chamber tremors, paneos and angles that are typical of the kinematics of well -positioned virtual games and cameras and we will have to wait to watch the first video with gameplay. However, I return to my argument of ‘Red Dead Redemption 2’: Seven years later, the adventure of the … Read more

Apple does not know how to meet their environmental goals, so they have started planting trees crazy

The Big Tech are in the middle of a change. Not that of artificial intelligence –that too-but that of Achieve carbon neutrality. On this path to decarbonization with Objectives for 2030 and 2050Apple is one of the companies that have the most interest in users to know that they care about the environment. In fact, in the presentation event of the iPhone 15 and of Apple Watch Series 9being one of the most important technological events of the year, the company shared a Fun video. In it, their mandamases met with the representation of the Earth to inform about their progress in reducing emissions, the installation of Solar panels in California and the increase in recycled materials on its devices. But renewables are not enough to achieve those objectives, and Apple has made the decision to plant tens of thousands of trees. He is doing it in Brazil with the aim of reconverting grasslands in forests that catch carbon, but everything that shines is not gold. A two times bigger forest than Manhattan There is a trend among companies that we are seeing in recent years. To reduce carbon emissions, it is not enough to install more renewable, reduce the consumption in your data centers and optimize transport. In Fast Company We read that these actions are not enough to reach the objectives and that the secret is in the direct capture of CO₂ (and there are controversy about it about its effectiveness). We are seeing how there are companies that are investigating the creation of buildings that capture carbon dioxide, but also experiments to discover What kind of trees They are the ones who catch the most. Apple ha reduced Emissions in 60% compared to 2015 and expect to reach 75% of a 2030. The problem is to exceed that figure and reach 100% in the face of 2050. Chris Busch is the Director of Environmental Initiatives of Apple and comments that they do not have “a clear line of vision of how to avoid these broadcasts today.” It seems that they have reached a point where the use of renewables is not enough and you have to move on to a new approach. “And that’s where nature comes to play a role,” says Busch. In 2021, Apple destination 200 million dollars to a fund to help in the creation of environmental and carbon elimination projects, something for which it promised additional 200 million dollars in 2023. During these last two years, different associations with the support of this member of the Big Tech have replanted more than 10,000 hectares in an area southwest of Brazil. The idea is to reconvert areas for grazing and livestock in forests that not only recover trees to capture CO₂, but also the return of local fauna such as rabbits and pumas to an ecosystem that had been very damaged by other types of activities. It is an effort part of a major program that seeks to restore almost 300,000 hectares of degraded land in Brazil, Uruguay and Chile. Apple is not only helping financially, but also at the technological level. And, obviously, this is not selfless. “What we intend is to generate financial performance as a investor in these projects,” says Busch. This yield will be in the form of lower payments for their CO₂ emissions and the manager also comments that the global objective is shared. “We have to reduce emissions as soon as possible, but also put an end to deforestation and increase carbon elimination to maintain within 1.5 degrees”He said. And this is not just about planting trees. The Cupertino are technologically supporting project monitoring, such as the measurement of the trees’s trunk diameter, but they are not the only ones. Google, goal or Microsoft have also created coalitions To plant trees and compensate for their greenhouse gas emissions, and companies that are not within that select group also have reforestation initiatives. It is not planting by planting Now, you have to be careful with the type of trees that are planted in these reforestation programs. And with other factors. In Fast Company they point to a controversy in this concrete reforestation because they are planting eucalyptus. They are trees with potential to evolve in punished terrain, such as ancient animals for animals, and grow rapidly absorbing large amounts of co₂. The problem is that reforestation reduces rainfall and eucalyptus, precisely, need water, so critics point out that these plantations will do will end underground water reserves. Also Questionable actions have been produced. In Pakistan, mass reforestation programs came into conflict with the practices of nomadic communities, something that has also occurred in places in China or Brazil itself. We must not go so far: in Europe we are reforesting huge areas with trees that are suitable for that reforestation, but that They may not reach 2100. The reason? They are species that or are not native or, even if they are planting without taking into account possible future pests or the effects of climate change. Research has also been carried out that the effectiveness of these projects is limited. As they comment on The Guardianmost of these projects do not generate real climatic benefits and there are areas that are being reforested in which there was no real risk of deforestation. The point by which some actions have been undertaken is due to the overestimation of the emissions avoided. And the study does not point to 10 or 20% of these reforestation actions, but 90% of them. As much as it may be, planting trees is positive whenever it is done with the head, but as Forrest Fleishman, an expert in mass plantation of trees, rather than planting trees, must be made.

If you talk to your plants even if everyone thinks you are crazy, science has something to tell you: you’re not so crazy

When in January 2012, Risto Mejide said that of “You sing like a diva, but you move like a plant“I did not know that I was completely wrong. And not only for Natalia, the contestant of ‘You do vouchers’ to which he directed those pearls, but because, under that static appearance, the plants do not stop doing things. And not by chance, no. Plants are not only able to detect threats, but activate a whole series of defensive reactions that have intrigued scientists for decades. Everything starts with a bite. Heidi Appel and Rex Cocroft met at a seminar at the University of Missouri and, quickly, saw that His interests fit. Cocroft was one of the great experts in biotremology (the branch of biology that studies the role of vibrations and sound in life) and had been analyzing how insects use the stem of plants to communicate. Do you listen? Apple was an expert in ecological chemistry and listening to those recordings (specifically how the caterpillars of the butterflies of the Col bit tiny mustard plants) had an idea: what if the plants could listen to them? And if that explained that, suddenly, plants activated a whole series of physiological reactions to “attack” the caterpillars? Answering that question was not easy. We had to measure laser vibrations and try to understand what plants could really hear. On the other hand, we had to quantify “how plants care and how.” However, it was enough to measure in real time what happened to the first bite of an caterpillar to verify that, indeed, the plants listened. And not just that. “What is surprising and great is that these plants only create defense responses to feeding vibrations and not to wind or other vibrations in the same frequency as the chewing caterpillar,” Appel explained. They discovered that, in fact, it was enough to expose plants to the sound of chewing so that glucosinolate levels (that defensive response) triggered. Does this mean that putting music to plants is a good idea? No, it doesn’t mean that. “This field is somewhat obsessed with its history of putting music to plants. That kind of stimulus is so far from the natural ecology of plants that it is very difficult to interpret their answers,” Cocroft explained. What it really means is that what we usually think about plants is often wrong. A mistake that, little by little, we are waking up.

Media Spain has gone crazy with the question of whether olives fattening or not. But its biggest problem is not calories

“Do olives fattening?” In recent days, this question has run like gunpowder online and should not surprise us. It is one of those things that becomes viral from time to time: it is a typical case of very common product at the gastronomic level, but deeply unknown at the nutritional level. Let’s see what the science of olives and the rest of the pickles say. An urban myth. As the nutritionist Pablo Ojeda pointed out a few days ago, the idea that “the olives fattening” is close to the urban myth. And not only because, in short, food does not fattening or thinning for themselves (that is something that has to do with the general caloric deficit and not a specific product). It is an urban myth because it arises from a truth: that, According to the Spanish Food Composition Database92% of the energy provided by an olive It is fat. It is the nutrient that they contribute most with a lot of distance on carbohydrates or proteins. And that (even if that fat is “good”) destroys the nutritional profile of any product. However, if we look at other parameters we will see that, for example, the caloric density of these products is not very high. That is, you have to eat many olives so that that contribution is really noticed. Is the same thing with the rest of the pickles? In fact, olives are surely the most caloric pickles. In general, these types of products have very few calories. Classic pepinillos have about 12 calories per 100 grams, onions about 30. In comparison, it is true that olives have a greater caloric contribution: 120 green and up to 289 blacks. The real problem is salt. Because seen that, it may seem that pipinillos are a nutritional jewel. And, although they do not have many calories, what is certain is that they are very uploaded. To get an idea, WHO advises that salt consumption Do not exceed 5 grams a day. Well, only pipinillos are 2.3 grams per 100. In a context in which salt consumption does not cease to rise (promoted, above all, by the ultra -processed), care must be taken because it is a very important risk factor of cardiovascular diseases. And the probiotics? Here is some confusion because, although it is one of the fashion themes, still We know very little about the microbiota of our digestive system. On the one hand, yes: there are traditional products that are fermented in brine and, indeed, these They can have microorganisms to help us with the microbiota (although either much). However, “pickles” comes to mean ‘conserving in vinegar’ and in that environment it is difficult for interesting probiotics to remain. Most of what is sold in the market, in fact, has none. Beyond, this is, we must remember that the evidence that sustains probiotics is still scarce. It is not worth obsessing with them because, in most times, Its impact on health is zero. What matters As we often rememberIt is wanting to eat better. Everything else is literature.

The Atacama desert is one of the most arid places on the planet. And right there a handful of “crazy” is trying to get water out of the fog

The oceans and seas house, According to estimates Used by the United States Geological Service (USGS), more than 96.5% of the water on our planet. In contrast, The atmosphere contains A modest 0.001% of this total. The clouds, fog and moisture of the air itself contains somewhat less than 13,000 cubic kilometers that also represent 0.04% of the planet’s fresh water. But in contexts in which the drought squeezes, each drop can count. Collecting water from the fog. A group of researchers He has successfully tested A method to obtain water from the fog. The system was able to collect between 0.2 and 5 liters of water per square meter and day. Secarral To test the method, the team responsible for the analysis resorted to the Municicpio of Alto Hospicio, located in the Atacama desert. This desert houses some of the most arid areas on the planet, in which rainfall barely reaches the annual millimeter. The city depends for its supply of the water contained in underground aquifers, but According to the team itselfthese have not been duly recharged in a period of between 10,000 and 17,000 years. The city extends rapidly and fruit of it around 10,000 of its residents live in informal settlements, almost all of them disconnected from the water supply system. “The collection and use of water, especially unconventional sources such as fog water, represents a key opportunity to improve the quality of life of the inhabitants,” explained in a press release Virginia Carter Hamberini, co -author of the study. A “new” method … A study that managed to show the potential of this technology. The team tested these mechanisms in the surroundings of the city of Alto Hospicio for a year, obtaining between 0.2 and 5 liters per square meter and day. Between August and September 2024, during the season of greatest activity, it was possible to reach up to 10 liters per square meter and day. “This research represents a notorious change in the perception of the use of water from fog, from a rural and rather small -scale solution to a practical water source for cities,” adds Carter Humberini. “Our findings show that fog can serve as a complementary source of urban water in dry areas where climate change exacerbates water deficiencies” The mechanism also has its limitations, they clarify. One of them is that its use is limited to high elevations outside the city limits. … that is not so new. The collection of fog water is not something novel, as Carter Haberini recalls, but it can be a convenient method to be climbed in a context like the present. The Fog Water Collection Appliancessuch as the one used in the study, they consist of a network through which the air loaded with moisture circulates. Part of that moisture is coupled to the fibers of the network and falls through them to a channel that leads to a deposit. The water of the deposit can thus be used in a variety of uses such as human consumption or agriculture. The details of the experiment were published In an article In the magazine Frontiers in Environmental Science. Learning lessons. The viability of fog water collection depends on the geographical characteristics of the environment: both climate and orography can affect the ability of this mechanism to provide water. These favorable conditions can occur in some areas of Spain, where already There are those who consider similar projects.

The crazy plan of Scotland to save forests

If science is not wrong, and We have decades of examples To believe that does notthe climatic emergency is increasingly important to try to go some step ahead of that elephant in the room that is made to us with the climate of our planet. In recent years we have seen proposals of all kinds, since Fill the diamond dust stratosphereuntil cause desert rains with solar farms. The United Kingdom has just added one that nobody saw coming. Reintroduce the wolves in the highlands. Now, A study by the University of Leeds suggests that The reintroduction of wolves in the highlands of Scotland could promote the expansion of native forests and contribute significantly to carbon capture. According to researchers, this process It would allow to store up to 1 million tons of carbon dioxide (CO₂) per yearwhich would represent approximately 5% of the carbon elimination objective of the United Kingdom in its forests. Context: The impact of running out of no wolves. Over the centuries, the wolves have been persecuted throughout Europe due to its impact on livestock and the direct orders of monarchs. Namely: in England, King Eduardo I (1272-1307) ordered his total eradicationprocess that culminated under the reign of Enrique VII (1485-1509). In Scotland, due to its mountainous geography and low population density, The wolves managed to survive until the seventeenth centuryalthough with constant persecution. Already in 1283, rewards were paid for lobos hunters in Stirling, and In 1427, King Jacobo I of Scotland promulgated laws for extermination. However, His final disappearance occurred approximately 250 years ago. For all these reasons, the eradication of the wolves generated ecological consequences, one of the most serious being the overpopulation of red deer, a creature out of control right now. In fact, Today it is estimated that there are 400,000 red deer in Scotlanda figure that has grown without control in the absence of natural predators. This increase has led to A serious overpair problemsince deer feed on young tree shoots, preventing the natural regeneration of forests. How can the return of these creatures help. The study used A Markov predator-prison model to analyze the effects of the reintroduction of wolves on the ecological dynamics of Scotland. The findings suggest that A population of approximately 167 wolves would reduce the density of deer to less than four deer per square kilometerallowing trees to grow again naturally. They count on their study that among the ecological and climatic benefits of this measure they include The expansion of native forestswhich currently cover only 4% of the Scottish territory, making it one of the less forested regions in Europe. Also carbon capture, with a potential of one million tons of co₂ per year Thanks to the increase in forest mass. And finally, the economic value of reintroduction, since Each wolf would contribute to the absorption of 6,080 tons of annuals, which is equivalent to 154,000 pounds per wolf in terms of carbon capture value. The main author speaks. In this regard, Professor Dominick Spracklen, principal author of the study, stressed the need to address the climatic crisis and biodiversity crisis jointly. He stressed that natural processes, such as species reintroduction, can play a key role in the recovery of degraded ecosystems and generate benefits for both biodiversity and climate. Challenges of the proposal. Of course, such an idea is not new. In fact, now We have seen other cases in the past where it was sent to predatory enclaves to tartar to limit or exterminate other animals, Sometimes with disastrous results. In addition, although the proposal has great ecological potential, the reintroduction of the wolf in Scotland remains a controversial issue and would require careful management, especially in areas close to human settlements and livestock areas. The authors point out how problems to take into account Conflicts with farmers and farmerswho fear attacks on cattle, The resistance of deer hunterswhose activity could be affected by the reduction of the population of dams, and Public perception and social acceptancesince the presence of wolves generates concern in some rural communities. In this regard, the study co -author, Lee Schofield, emphasized that before considering any reintroduction, It would be essential to carry out a public consultation and involvement process of the parties interested. He also stressed that conflicts between humans and predators are common, so any strategy must include policies that mitigate the impact on the population and economic activity. The future of the wolf in Scotland. At European level, the wolves have managed to recover part of their historical territory, with an estimated population of 12,000 individuals in Western Europecurrently occupying 67% of its original area. In countries such as France and Germany, the reintroduction of the wolf has generated intense debates, and in some cases, Compensation programs for affected farmers have been implemented. That said and how we indicate, if Scotland decides to move forward with the measure, it would join a growing global movement that seeks to reintroduce predators stop as a tool to restore ecosystems and face climate change. The success of this project would depend on the implementation of adequate management strategies that balance ecological conservation with the needs of local communities.

If it seemed to us that time was driving crazy, we now have a new phenomenon: “The ghost girl”

We have spent months Waiting for the arrival of the girl. Countries, agencies and universities have dedicated hours and hours to try to find out how to prepare for what was coming and the truth is that there was not necessary to prepare too much: the girl is being very weak and moderate. Good show of this is that, despite being the great refrigerator of the world, January has been the warmest January of registration. Is it strange? It is not unheard of, of course; But it is not normal. In fact, the NOA “He has expressed his surprise Seeing a strong atmospheric component of the girl without the corresponding colder surface temperature than the average of the tropical Pacific. “ We could say that the phenomenon has been playing with us for weeks. It is as if it were, but without being completely. What will happen to the girl? As Martín León explains“The average of the dynamic IRI model and several models of the Multi-Model set of North America predict an earlier transition to enso-neutral in January-March of 2025”. A priori, the most likely scan is this, but “There is a 41% probability that Emerge Emerge Emerge in this season.” This means that, in aggregate terms, it is expected that “the girls of the girl persist in the short term, with a probable transition to enso-neutral during March-May of 2025 (66% probability).” And then? The international climate community is nervous because we must not forget that the 2023-2024 child was The fifth strongest Since we have records and the fact that the girl is so soft raises many doubts: is it that the Enso is moving towards a structure much warmer What is accustomed to us? It is not clear and is more than a fear than a prediction. But it is clear that what are good news (Few impacts due to a weak girl) It is becoming a source of uncertainty. No one knows if we will end the year in another the child, but the possibility is on the table.
