They have studied the effect of long -term sweeteners on our brain. His conclusion is that he ages faster

by

Little by little it is already becoming a daily gesture among many people: change sugar for a sweetener to avoid calorie consumption in excess. Whether in the morning coffee, in a yogurt or in a refreshing drink, sweeteners are attractive to respect the sweet taste and ‘be healthy’. However, a new and forceful study Posted in the prestigious medical magazine Neurology He puts this idea in check, suggesting that this substitution could have a long -term hidden cost for our cognitive health. A direct effect to thought. Research, which has established itself as one of the broadest and most prolonged to date on the subject, cooks that people with high consumption of sweeteners such as the aspartamosaccharin or sorbitol They experience a deterioration of their thinking and memory capabilities 62% faster than those people who consume. To put it in perspective, the researchers calculate that this accelerated decline is equivalent to aging 1.6 years suddenly. The details of the study. It is not a PSAJERA survey or a small -scale experiment. Scientists have been based on the Brazilian Longitudinal Health Study data of the adult (Elsa-Brazil), a mass and long-distance research project. They analyzed a cohort of 12,772 public officials with an average age of 52 years, which were followed for eight years, and with analysis at three different moments: 2008-2010, 2012-2014 and 2017-2019. Detailed questionnaires. Using food frequency questionnaires, the team quantified the combined and individual consumption of seven specific sweeteners: artificial ones such as aspartamo, saccharin and acesulfamo K, and sugar alcohols such as erythritol, xylitol and sorbitol, in addition to the tagatose. In parallel, the cognitive performance of patients with a six -test battery that focused on memory, verbal fluidity and global cognition was measured. The results. The consumption of sweeteners, both individually and combined, was associated with accelerated cognitive loss. The ‘suspect’ list includes some of the most common names we find on the labels of ‘Light’ products or ‘zero’: aspartamo, saccharin, acesulfamo k, erythritol, sorbitol and xylitol. Interestingly, the trend was more pronounced and statistically significant in participants under 60 years. This suggests, according to the authors, that median age is a critical window where the products that are chosen consumer may have direct consequences in brain health decades later. The researchers They point that until now the sweeteners without calories often “are seen as a healthy alternative to sugar.” But now it has been seen that great consumption of these has “negative effects on brain health over time.” There are limitations. The researchers themselves suggest that dietary data are based on self -reports, which can be inaccurate, and that, despite statistical adjustments, the “residual confusion” cannot be completely ruled out where other nutritional behaviors that may be interfering are not measured. Correlation is not causality. As expected, this study can generate a great debate, and the industry and the scientific community have called for prudence, remembering that correlation does not imply causality. Gavin Partington, general director of the British refreshing drinks association, and the International Association of sweeteners (ISA) They have pointed out that this is an observational study. That is, it finds a statistical association between two variables (consumption of sweeteners and cognitive impairment), but cannot demonstrate that one is the direct cause of the other. In Spain, experts such as neurologist Guillermo García Ribas, from the Ramón y Cajal hospital, They are cautious. He criticizes that it is difficult to isolate the effect of the sweetener of the rest of the diet. Often, a high consumption of these products goes hand in hand with a diet rich in ultraprocessed foods, which have already been linked in numerous studies to a worse cognitive aging. The defense of researchers. Anticipating this criticism, the Suemoto team offers two solid arguments. First, they observed that the association was also maintained for individual sweeteners, those that a person adds on their own to coffee or yogurt, and not only for the compounds used by the industry in the ultra -processed. Second, and perhaps more important, there is what scientists call “biological plausibility.” Previous studies carried out in animal models (mainly mice) have already shown that artificial sweeteners can trigger neuroinflammation processes and alter the crucial intestine-cerebro axis, mechanisms that could negatively affect brain function. The global context. This study does not arise in a vacuum. It adds to a growing wave of skepticism on the long -term benefits of sweeteners. In fact, in 2023, The World Health Organization (WHO) itself advised the use of these products to control the weight or reduce the risk of chronic diseases, arguing the lack of evidence on its long -term benefits and the existence of possible unwanted effects that had not yet been completed. The underlying problem remains the same: excessive sugar consumption. In countries like Spain, the maximum daily amount recommended by WHO is tripling. The sweeteners emerged as an apparent solution, but studies like this force us to ask ourselves if we are simply changing one problem for another. As Suemoto himself summarizes, his work “adds solid evidence that these compounds may not be harmless, especially when consumed frequently from the median age.” The conclusion is not that we should return to sugar, but that we must examine much more critically with what we are replacing it Images | Towfiqui Barbhuiya In Xataka | 9 questions and answers about Estevia, the fashion sweetener

August has been an extremely warm month in Spain. That has had a side effect: make us older

by

This summer has left repeated scenes: empty squares at the time of the nap, nights in the heat and a Mediterranean turned into a pressure pot. Spain has suffered suffocating days They will go to statistics, but the most serious is not measured in degrees. According to a recent study, heat waves do not leave when the temperature drops. They leave a silent trail in the body: they accelerate biological aging. A disturbing finding. A recent study Posted in Nature Climate Change It has shown that repeated exposure to heat waves accelerates biological aging. The work, led by the University of Hong Kong, followed 25,000 people for 15 years in Taiwan. The results speak for themselves: four extra days of heat wave in a period of two years were translated in nine days added to the biological age of the participants. In manual workers, more exposed to the sun and heat, that effect shot up to 33 days. “The impact of heat on our body is comparable to tobacco, alcohol, poor diet or lack of exercise,” The research team has summarized to The Guardian. The biological clock under pressure. How did they get to that conclusion? The scientists calculated the biological age from different markers: blood pressure, inflammation, cholesterol and the functioning of lungs, liver and kidneys. When comparing them with the real age of each person, the conclusion was clear: who had spent more time under heat waves showed accelerated aging. The exact reason is still unknown. The main hypothesis is that high temperatures damage DNA and submit the body to constant stress. “If the exhibition accumulates for decades, the impact on health will be much greater than we have now measured,” has pointed to The Guardian Dr. Cui Guo, main author of the study. More evidence: heat at all ages. This finding does not come alone. In 2024, another job Posted in Nature He revealed that early exposure to cold and heat interferes with the development of the white matter of the brain in children. The consequences, the authors warned, could extend throughout life. The conclusion is clear: heat does not understand ages. Inference affects developing brains; In adulthood, it accelerates the organism’s wear. Can the damage be stopped? The same study offers an interesting nuance: the harmful effect seemed to be reduced over time, probably because people learn to protect themselves better. Searching for shadow, hydrating or using air conditioning made a certain difference. Even so, the biological footprint never disappeared completely. The problem is that not everyone has the same possibilities to adapt. Older people, outdoor workers or those who live in neighborhoods with less resources suffer a much greater impact, As the study collects. Prevention, experts coincide, goes through reinforcing Urban design: More trees, more shadow, better isolated homes and just access to cooling. Individually, recommendations remain simple but effective: hydrate, avoid hours of heat and seek refuge in fresh places. The invisible heat scar. Until now we thought about heat as something passenger: annoying, exhausting and dangerous in extreme days. But scientific evidence points to something more disturbing. The heat, the experts say, does not leave at all when the thermometer goes down: it stays inside, accelerating the wear of the organism and leaving an invisible scar. For researchers, this finding is a turn in the way of understanding health. And the warning is clear: if the planet continues to heat up, we will not only have longer summers, also bodies that age faster.

The effect of heat on our heart rate when playing in summer

by

It is the summer stamp: go running or riding by bike and, a few minutes later, the pulsometer is triggered to figures that do not correspond to the effort. And it’s not a strange thing to see. It is the body that is trying to respond to a series of stimuli such as heat and exercise, and understanding its physiology is important for Do not turn sports into a health risk. Exercising in summer is a great challenge. In this situation the body is forced to respond to two specific demands. On the one hand, Muscles in action need a lot of energy in the form of ATP To contract. However, this is an inefficient process, since It only takes advantage of between 20 and 25% of the ‘produced’ energy releasing the remaining 80% in the form of heat. This energy in the case of not dissipating it correctly can raise internal body temperature by 1 ºC every 5-10 minutes. How to avoid it. On the other hand, to avoid precisely that lethal overheating, the body thermoregulatory center located in the hypothalamus, Activate powerful cooling mechanisms. One of them is to pump huge volumes of hot blood from the body nucleus to the skin, causing it to be red by that large amount of blood that is going through the surface of the body. This double duty is the fundamental reason why the pulse shoots and becomes the most sensitive and critical indicator of the stress to which the body is subjected The organism has to compensate. These two situations cannot be carried out in parallel, but A balance must be achieved. And it is that when the system is taken to the limit by the intensity of the exercise and the severity of heat, something has to yield. Or blood flow is reduced to the muscles, limiting the ability to maintain rhythm, or the flow to the skin is committed, limiting heat dissipation and increasing body temperature to dangerous limits. Understanding this internal negotiation is key to understand why training in summer is much more than a simple matter of willpower. The skin becomes a giant radiator. The first and most powerful response of the body to the increase in skin temperature and body nucleus It is body vasodilation. Controlled by the ‘thermostat’ of the body, the preoptic area of ​​the anterior hypothalamus, this mechanism causes the blood vessels close to the skin to widen and make it become a refrigerator. Under resting conditions and neutral temperature, the cutaneous blood flow is just about 300 ml/min. However, during an intense exercise in a hot environment, this flow It can shoot until reaching 7 or 8 liters per minute. Something that also represents around 50 and 70% of all cardiac output. And this is a simple deviation of resources with the objective of dissipating heat by convection and radiation. Although it is not free. It has an important cardiovascular cost. The heart accelerates to compensate. The fact of opening the ‘pipes’ that lead the blood to the skin causes the heart to have to activate an important compensation mechanism so that the organs remain perfused. We talk about heart rate, which will be increased. The objective is to maintain cardiac output, so that blood pressure is stabilized despite the low peripheral resistance due to vasodilation. A crucial aspect of this process is speed. The initial increase in heart rate is an incredibly fast neural reflex, triggered by Thermal skin receptors. This response often precedes any significant increase in central body temperature. This shows that the body not only reacts to heat, but anticipates it, preparing the cardiovascular system for the thermoregulatory battle that is coming. The key is in cardiovascular drift. Any athlete who trains with a pulsometer in summer will have noticed a disconcerting phenomenon: even maintaining a constant rhythm, the pulse tends to rise progressively throughout the training. This is something that has been documented and called ‘cardiovascular derives‘, which is defined as the gradual and continuous increase in the heart rate that occurs during a prolonged exercise of constant intensity, accompanied by a decrease in systolic volume (the amount of blood that the heart pumps in each beat). And precisely the heat stimulates the two mechanisms that drive this phenomenon: The increase in skin flow by vasodilation. This causes blood to ‘stagnate’ temporarily on the periphery, which reduces venous return. This means that the heart does not fill so much in each beat, and therefore the amount of blood that will expel will be less. Dehydration Sudoration is essential to cool the complete system, but it entails a loss of body fluids, mainly from the blood plasma. This again reduces that the blood returns to the heart so that the same volume can be pumped. And to compensate the only thing left is to increase the heart rate. The pulse increase per centigrade grade. Once the ‘why’ of this increase in heart rate is known, an athlete is interested in knowing the ‘how much’. And the reality is that studies have established a very useful general rule to know how our body temperature increases when exercising: In dry heat conditions, with environmental temperatures above 24 ° C, the heart rate Increase approximately one beat per minute for each celsius degree of temperature increase. In wet heat conditions, the impact is multiplied. Here the increase in heart rate triggers between 2 and 4 beats per minute for each degree Celsius that increases the ambient temperature. This difference is not trivial. Exercise at 34 ° C in a dry climate (10 ° C above the threshold of 24 ° C) could involve an increase of about 10 beats per minute in the heart rate for the same effort. On the other hand, to those same 34 ° C, but with a high humidity, the increase could be 20 to 40 beats per minute. This additional load on the heart explains why we call as ’embarrassing’ feels much more … Read more

The urban heat island effect

by

Summer is here and with him the desire of millions of people to escape the city. The east desire is more than the mere enjoyment of the beach, leisure or rural landscapes, there is also the prevailing need for escape heat. And part of the fault of this lies in the so -called urban heat island effect. What is the urban heat island effect Heat island? The term refers to the fact that cities They tend to accumulate heatwhich implies that the temperature in them is usually higher than in their surroundings. This effect can be felt during the day but it is perhaps at night when the difference between urban temperature and that of its surroundings is greater. The difference can be several degrees. An estimate For example, he calculates that the difference between New York City its surroundings is around the 4th Celsius. A recent study made in five Spanish cities estimated that the average variation in Madrid was 1.3º, but in Valencia reached 4.1. The responsible team came to measure differences of up to 11 between the center and the periphery of the Spanish cities studied. How a heat island occurs The causes of the heat islands There are several and diverse. The construction materials we use tend to absorb energy that they release during the night. This makes night temperatures do not descend in the city as much as in other contexts, thus accumulating heat. The buildings, in addition, block the passage of the air that would drag the heat accumulated in the day to day, while the absence of trees and of phenomena such as the evaporation of soil water contribute to a worst thermoregulation of the system. The other great factor responsible for urban warming is human activity. Many of our activities, from driving to heating a pout generate residual heat. Even when we cool things, for example when we use the air conditioning, the thermal “balance” is positive. What factors aggravate the problem We pointed out before not all cities experience a heat island of the same magnitude. The complexity of the factors that cause this phenomenon is responsible for it. Knowing this, we can list some factors that can influence the degree in which a city stands out from its thermal environment. Among these factors We could find Population density, orientation and structure of its street, characteristics (height, materials) of its urban buildings, vegetation and trees, the passage of rivers, or its location with respect to geographical elements such as the mountains or the coast. Even the color of the buildings, including its roofs, affects the temperature differential. The heat island in the city of Paris. Copernicus Climate Change Service, ECMWF. Consequences of the heat islands The direct consequence of this phenomenon is an increase in temperatures, which in turn affects a multitude of Aspects of everyday life of whom these cities inhabit. Both at night and day. Heat can have consequences on our health and well -being: heat strokes, Difficulty reconciling sleep or to concentrate or an increase in the risk of suffering the effects of certain diseases such as cardiovascular, among other problems. Urban heat can be somewhat positive in winter or certain climates from the energy point of view, but in summer it will imply that we will spend more to cool our homes, work areas and even our refrigerators. A problem that will go to more There are two factors that invite you to think that this phenomenon and its consequences will go worse in the coming years. The first, climate change. Perhaps the phenomenon that we mostly associated with climate change is the increase in the average temperature of the planet. This temperature increase can be added to the increase associated with urban heat island, thus increasing the risks and problems associated with this phenomenon. The second factor to consider are migrations, specifically the rural exodus. A growing proportion of people live in cities, some of them already host dozens of millions of people. The biggest cities They are more susceptible to suffering the problem of urban heat island. In addition, the more people live in them, the more people the impacts of this temperature increase will be vulnerable. How to prevent the heat island effect Urbanization is a process that continues, especially in the “developing” countries, so all we can do is search ways to reduce impact of these heat islands. To do this, understanding its causes and dynamics is essential. The solutions that They have been proposed To avoid heat accumulation in cities are diverse, but the possibility that they can be implemented depends on various factors. For example, in an area still under development, we can encourage architectures that optimize air flow and reduce the presence of materials that capture heat easily. It is also important to leave spaces to non -urbanized areas, natural and seminatural environments such as parks and urban forests. The introduction of trees and other green areas () can also be feasible in already built areas. The mere Presence of trees On an avenue you can significantly reduce the insolation that reaches the ground and thereby prevent it from hot as much as it would happen without the trees. In this sense, even the use of paintings that increase the solar energy reflected again to the atmosphere (if we paint a roof or a white square, for example) it can also become a useful resource.

If you have the feeling that everything is more expensive than ever, it is not your imagination: it is called “Zillow effect”

by

Digital platforms promised to make everything easier and cheaper. Actually, they have created the opposite phenomenon: The “Zillow Effect” is taking practically everything What we play online, whether digital or not. Why is it important. When any transaction is digitized, the demand is triggered because it eliminates friction, but the supply remains constant. The result is usually the same: prices go up and competition intensifies for buyers. The panoramic. The effect began in the real estate sector with Zillow in the United States, A real estate platform born in 2006 which allowed anyone to consult the value of their home. Now it extends to university candidates, employment searches, appointment applications, concert tickets, vacation destinations and even second -hand markets. If you can buy it with a click, it is probably more expensive than before. In detail. The mechanism is simple: Before, requesting place at a university required physical effort. Get forms, send them by postal mail, go to pay fees. Now, with a button you can send your application to twenty universities. Result: the best receive many more requests, they can be more selective and the competition to access goes up to the same pace that their access barriers are lowered to the application. The same happens in the labor market: For candidates, there is a paradox: getting a job becomes more complicated. The contrast. There are two large categories of products here: Products with elastic offer. They are the ones that can be manufactured in greater quantities. Clothing, processed food, smartphones. They have been cheaper. Products with limited offer, or by regulation or by their own nature. Housing in good areas, places of universities, more desirable jobs, very attractive sexual couples. They have fisher, financially or symbolically. Between the lines. Great technology benefit from this problem, so they have no incentive to solve this problem. More demand is equivalent to more data, more engagementmore commissions. The case that gives name to this effect has a perfect example: Zillow earned money both if the houses were sold as if notbecause he charged for teaching them. AND Your platform fired your visibilitywith the aforementioned consequence: same supply, greater demand … upward prices. The threat. The Zillow effect has as first victims local and imperfect markets where opportunities could be found before. There are no longer the secret restaurants, virgin and quiet holiday destinations, or jobs that only a few knew. Google Maps, LinkedIn, Instagram or YouTube have democratized knowledge, but have also concentrated demand. An example: Instagram and ‘Tourism of Likes‘. And now what. A possible solution would increase the offer where possible, such as building more housing or creating more university places. Another would artificially limit digital demand. But there are not too many incentives for it. The digital world has connected us in this century, but it has also put us to compete against many more people for the same limited resources. And there is only a great winner: the platforms. In Xataka | 34 futuristic predictions made in the past: erroneous, successful and crazy Outstanding image | Xataka

Ozempic and blindness, we have been on the track of an extremely rare adverse effect for months. Now the AEMPS has taken a step forward

by

A few days ago the The United Kingdom warned on an unexpected effect associated with the use of Ozempic and treatments based on the same principle, the phenomenon of Ozempic Babies. Now the Spanish Agency for Medicines and Health Products (AEMPS) has also issued a statement but this time as a consequence of a very different effect. Adverse reaction. This week the AEMPS, the agency in charge of ensuring that the drugs meet the required standards, has issued A statement To warn of a very uncommon ocular adverse reaction “associated with treatments based on the semaglutida, the active compound of drugs such as Ozempic, Rybelsus or Wegovy. The notice occurs after the Committee for the Risk Assessment in Pharmacovigilance (PRAC) of the European Medication Agency (EMA) reviewed the risk of developing an ocular condition called Niana, which can cause loss of sudden vision. While the agency affects that the frequency of appearance of this type of eye problems is “very low”, it recommends that a sudden loss of vision is carried out an ophthanmological examination for Evaluate the possibility to interrupt the treatment. Noiana. Noiana is an acronym that refers to calls Previous ischemic optical neuropathiesNaion in English. These ailments are caused For the infarction of the optic nerve head. In other words, blood does not reach this eye region and a loss of vision occurs, which is typically fast but painless. It is an unknown and infrequent disease, not only in the context of those who follow a trailer treatment: its prevalence in the general population is approximately 10 cases per 100,000 inhabitants. A year on track. A year agoa study I found indications of the relationship between the treatments of Semaglutida and Niana. Indications such as those that gave rise to the evaluation by the Pract. The Committee reviewed clinical and preclinical essay data together with suspicion of adverse reactions, explains the AEMPS. This work resulted in the conclusion that trailer treatment can be associated with a risk of developing this disorder but indicate that with a very low frequency. The AEMPS speaks of “an increase in the risk of developing Niana of approximately double compared to people not exposed to this treatment. This corresponds to an additional case of NOIANA for every 10,000 patients treated with semagglutida for a year.” And what about the “other ozempic”? The AEMPS statement focuses on the drug -based drugs such as Ozempic, Rybelsus and Wegovy but does not indicate whether similar effects have been detected on similar treatments such as those based on the tirzepatida, such as Zepbound and Mounjaro. A medication with side effects. Like any drug, the semaglutida has a series of Contraindications and side effects. It should be remembered in this sense that the success of drugs such as Ozempic began when it was observed that this treatment against diabetes made those who followed it lost weight.

The domino effect of tariffs is also being felt in Valencia. Specifically, in the Ford factory

by

Ford has drastically trimmed the production forecasts of the new bronco in its Almussafes plant. Of the 300,000 units initially planned, the figure has fallen to 209,000, as published Digital economy citing their own sources. Why is it important. This 30% cut reflects how Trump’s tariff policies are already moving chairs in the European industry before applying. The accuracy of the new figure – 209,000 units compared to the 300,000 round rounds – lets read a very specific calculation between a very specific projected stage between the lines. Between the lines. Suppliers openly speak of the “Trump effect” by explaining these changes. The most important reduction affects precisely the volume allocated to the United States: from 91,000 units per year provided for a much lower but not even pointed out. Ford is adjusting its transatlantic export plans in the face of tariff uncertainty. And that is felt in the Valencian economy, whose GDP depends by approximately 10% of this factory. In detail. The effect on the supply chain is, the redundancy, in chain: Suppliers have to recalculate investments. Prices should be modified based on a lower production volume. Lower production means less industrial capacity required. And that facilitates the transfer of suppliers outside the Almussafes environment. Yes, but. Trump will end his mandate in 2028, but bronco production is planned between 2027 and 2035. That is, three quarters of the manufacturing will be done without him in the presidency. But the car is an industry without much flexibility to modify the decisions that are made now. The threat. Reduce estimates during the award of limited pieces future expansions. If suppliers dimension their capacity for 209,000 vehicles, then increase production will be more complex and expensive. It is not easy to undo steps and make them again. The industry is creating a productive roof based on the most pessimistic stage. Deepen. Ford He is at the same time intensifying his presence in Moroccoparticipating in the Automotive Tangier meetings with the presence of the Moroccan monarch.

We thought that gasoline cars were much cleaner than diesel. We did not have the effect of the sun

by

For every 100 cars that are sold in Spain, just five are diesel. They are the latest data we have in Spain of registration, which reflects to what extent the diesel (despite having market niches in which It is still profitable) It has become an almost banished fuel in our country. And although it may be weird, it does not make 70% of the cars we bought were diesel moved. In fact, just over a decade ago. In 2014 the diesel lived his golden age. From its 70.06% market share It has plummeted. There are numerous factors that explain the rise and fall of diesel. For years, its price was so cheap (in fact it is still subsidized) than each buyer He poured liter calculations consumed For every 100 kilometers to know how long it would take to make investment profitable since they used to be more expensive motorizations. But over the years, emission regulations were drowning the diesel. Especially after the famous Dieselgate in which it was discovered that the Volkswagen Group (first defendant) and other companies trucan their emissions to offer data within the legality in the homologation exams to, outside them, contaminate more than allowed. With Euro 6, diesel were put much more complicated since 2015. For sample, the comparison between the demands made to diesel engines compared to gasoline and that You can read in this extensive article of Xataka in which all the normative change was explained: Limits for a gasoline engine CO (carbon monoxide): 1.0 g/km HC (total hydrocarbons): 0.10 g/km NOX (nitrogen oxides): 0.060 g/km HC + NOX (hydrocarbons and nitrogen oxides): 0.160 g/km (approx.) PM (suspended particles): 0.005 g/km P (number of particles): 6×10^11/km (6×10^12/km for three years for direct injection) Limits for a diesel engine CO (carbon monoxide): 0.50 g/km HC (total hydrocarbons): 0.09 g/km (approx.) NOX (nitrogen oxides): 0.080 g/km HC + Nox (hydrocarbons and nitrogen oxides): 0.170 g/km PM (suspended particles): 0.005 g/km P (number of particles): 6×10^11/km The problem is that, due to its own operation, A diesel is less pollutant in CO2 that a gasoline but expels many more particle emissions than They are very dangerous to the health of the human beinglike the Nitrogen oxides (NOX). Although the value was slightly higher for diesel, emission regulations were forcing manufacturers to squeeze the brain. With Euro 5 the particle filter. From Euro 6, the Adblue. These measures ended up banishing diesel engines of smaller cars. Well because they contaminated too much or because innovations to be installed in them It was more expensive both the product that did not make it viable. If we take into account the increase in the product, the bad reputation after the dieselgate and the innumerable statements On a rise in the price of fuel, now it is better understood The sudden drop in sales. All this explanation makes sense. Do you remember that Euro 5 forced to mount particle filters in diesel cars? And that with the Dieselgate the cars reflected some emission figures that were not real? A study now indicates something similar for gasoline cars. It is not that they are cheating, they point out that the emission regulations itself may not be enough to tell us how pollutants are our cars. A little effective particle filter In short, a particle filter is a kind of mesh that catches larger pollutant emissions before expelling them to the atmosphere through the exhaust pipe. Taking advantage of the heat of gases, the mesh takes temperature and burns the particles, reducing emissions. That is a problem in the cars that start and stop every time or those that do many kilometers by city because the engine does not give time to take the temperature enough to burn these particles and the filter ends up collapsing, causing a somewhat expensive breakdown. For some years, emission regulations have forced gasoline cars to also mont particle filters to get emissions not to exceed the allowed limits. However, as a gasoline engine works at a higher temperature, It is more complicated to fall into these types of situations. However, a study published in Science Advances He has pointed out a problem: they are not enough. The particle filter aims to reduce the Volume of fine particles that are expelled to the atmosphere, PM2.5. And they get it, according to researchers but that is not enough to ensure that their toxicity is lower. They point out in their study that it is not enough to measure emissions just after combustion, they should be studied how they behave once in the atmosphere. And how do they behave?: Bad. They point out that, once in the air, the experts expelled are exposed to sunlight and that they cause a series of transformations that make them remarkably more toxic to the human being. They explain in Phys.org that the modification of the particles caused damage to the human DNA and in cells that we find in our bronchi. It is what they call “photochemical aging” that causes particles to increase their toxicity generating “oxygenated volatile compounds, such as carbonilos.” In the article they point out that Dr. Mathilde Delaval, the first author of the study and researcher at Helmholtz Munich, says that “our study shows that we are missing a large part of the panorama by not considering How exhaust gases changeand become more harmful, after leaving the car. “ The study is partially financed by the European Union and in it they have intervened in one way or another universities and laboratories of Germany, Finland and Switzerland.

The “Ozempic effect” that is filling the mirrors with unknown faces
