the theory that explains why the rise in gasoline is here to stay

by

Gasoline skyrockets. It is the consequence of the attacks on Iran and the country’s responses to the United States and Israel. In an enclave very exposed to any type of crisis, the Strait of Hormuz, oil transit is suffering harsh consequences. China already warns that it will not export its fuel. And, meanwhile, gasoline is rising at a dizzying pace. 20 cents. Tomorrow, Saturday, March 7, marks one week since the United States and Israel attacked Iran. Since then, hostilities in the Middle East have continued, with a response from Iran in which its neighboring countries and even the European Union have been involved. It was February 28 and gasoline was moving below 1.50 euros/liter on average. When we write these lines, March 6, the portal dieselgasolina.com which monitors the price of Spanish service stations offers a very different image: So far this month, prices have skyrocketed: Gasoline 95: from 1,495 euros/liter to 1,608 euros/liter. +11 cents/liter Gasoline 98: from 1,687 euros/liter to 1,766 euros/liter. +8 cents/liter Diesel A: from 1,447 euros/liter to 1,643 euros/liter. +20 cents/liter Diesel A+: from 1,549 euros/liter to 1,734 euros/liter. +19 cents/liter A week. Barely a week has been enough for the price of gasoline and diesel to skyrocket and, above all… there is no prospect of their ceiling. And the oil companies and service stations are already beginning to notify the Government that they are not willing to support a new gasoline subsidy, as would happen in 2022. This means that the prospects are not at all promising and the truth is that if we look at the progress of the conflict, everything indicates that we can expect the worst. Right now: Sign of the increase in price in a few days like a rocket. What we are witnessing, again, is the theory of the rocket and the pen. When the supply chain falters, the price of gasoline skyrockets. However, its descent lasts for weeks or months, reproducing the effect of a feather. And, as soon as the last war in the Middle East began, gas stations have already started raising prices. It doesn’t matter that the impact of a rise in the barrel of Brent is not immediate on the prices at which they buy oil, the truth is that there are gas stations where prices have increased by more than 10% in the first days of the conflict, as you can see in the image above. The diesel. Although the price of gasoline is rising, without a doubt the biggest loser is the diesel customer. Spain continues to be a country whose automobile fleet is made up mostly for this type of fuel and seeing an increase of 20 cents/liter, on average, in just one week is hard. Its price is already higher than gasoline. What was once a historical raritytoday it has become a certain normality. As we already observed during the Russian invasion of Ukraine and the war in this territory, diesel became more expensive because Russia was a big exporter of the same and European refineries had been reduced. That is to say, we had less fuel available on the market and for what there was we had two options: buy it at a high price or wait for the European funnel to ease. And the room for maneuver is small. But, in addition, since the War in Ukraine the State has been applying some measures that reduce the room for maneuver to try to patch the situation. Public transport is now much cheaper that then and gas stations and oil companies have already raised the hatchet against possible subsidies. A tax cut seems complicated. The State would be shooting itself in the foot, reducing revenue that also goes up when fuel prices rise. AND The European Union has been pressing for years so that diesel bonuses are eliminated and, therefore, taxes are equal to gasoline.

There is a graphic that explains the atrocity that has occurred in Grazalema. And it helps to understand why the people continue to be evicted.

by

And that graph is Nahel Belgherzea meteorologist who covers extreme events throughout the world and who, despite being used to them, has described what has occurred in the mountains of Cádiz as “hydrologically absurd.” “Hydrologically absurd”? It is. Grazalema, according to available datahas received more than 2,000 mm of rain in the last 20 days alone. That is, more than a normal year of rain and we are at the beginning of February. It is not surprising that Spanish reservoirs accumulate 43,341 hm³ of water; that is, 5,634 hm³ more than last week. As of today, Spain is at an astonishing 77.34% of its total capacity. And, in fact, today, many reservoirs continue to drain before the arrival of more water. What do you see in the graph? The graph in question is very simple: it is the accumulated rainfall for the Grazalema station. On the Additionally, in gray, you can see the cumulates from other years. And, as you can see, the curve is almost vertical: it has rained unspeakably in a few days. Compared to normal years (when the river grows in spring and winter), there is now a totally enormous water boom. Something unprecedented. And, precisely that, is what is forcing CISC technicians to continue reviewing the Grazalema aquifer. While the City Council insists that the return of the residents will take place when a safe return can be “guaranteed”, researchers from the Geological and Mining Institute of Spain (IGME) they are still on the ground. The aquifer, a geological structure 18 square kilometers in size, has been put under enormous pressure and authorities are focused on ruling out the slightest risk of collapse before the town’s inhabitants can return. The Junta de Andalucía, in fact, has been warning for days that it can go for a long time.

What Zealand explains about climate change

by

For decades, geography books taught us that the world was divided into six continents. In 2017, the scientific community made official the existence of a new “intruder” of colossal dimensions: Zealandia. With an extension of 4.9 million square kilometers —equivalent to the entire European Union—, this mass of continental crust separated from Australia and Antarctica about 80 million years ago. What makes Zealandia an absolute anomaly is not just its size, but how well it has been hidden. Unlike the rest of the continents, 94% of its body is sunk under the Pacific. Only its highest peaks manage to show their heads, forming what we step on today such as New Zealand and New Caledonia. This geographical timidity kept it as a “ghost continent” until technology allowed us, finally, to pierce the abyss. The mission to rescue the past from the abyss. Everything changed in the summer of 2017. Expedition 371 of the International Ocean Discovery Program (IODP) It was not a pleasure cruise: the ship JOIDES Resolution set sail with a mission almost surgical. For two months, 32 scientists worked piecework, in 24-hour shifts, to extract “witnesses” from the seabed: cylinders of rock and sediment recovered almost five kilometers deep. These sediment cores are not just mud and stone. They are, in the words of paleontologist Laia Alegret, in statements collected by The Conversation, authentic “libraries of climate history”. The findings were surprising, despite being under the sea today, the scientists found pollen from land plants and spores, in addition to thousands of microfossils of organisms They only live in very warm and shallow waters. This confirmed that Zealandia was not always an underwater world, but had periods of land covered in vegetation. The “mirror” of future climate change. The relevance of Zealandia goes far beyond a geological curiosity. According to researchers from Rice Universitythis submerged continent constitutes a “critical region” for climate science, precisely because it is one of the places where current climate models show the greatest deficiencies. If models fail to accurately reproduce Zealand’s past climate, they warn, their predictions of future global warming may be incomplete or biased. The focus of attention is placed especially on the Eocene, between 53 and 41 million years ago, a time in which the Earth functioned as a true “greenhouse planet”. Carbon dioxide concentrations were much higher than today and there were no permanent polar caps. Studying this period in Zealand allows scientists to “look back at our future,” offering a glimpse of how the planet will respond to conditions extreme greenhouse effect greenhouse effects similar to those we could achieve in the coming centuries. One of the hottest spots. One of the most disturbing findings was the identification of episodes of rapid warming—rapid in geological terms, that is, on scales of thousands of years—during which ocean currents changed unexpectedly. The sediments reveal the arrival of deep water masses originating near Antarctica, a phenomenon difficult to explain in a warm world without permanent ice. This discovery, underlined by The Conversationchallenges the current understanding of how heat is redistributed in the oceans and forces us to rethink some basic assumptions of global ocean circulation. The violent birth in the “Ring of Fire.” Zealand’s history is one of a geological “roller coaster” driven by plate tectonics. According to the results published by the expedition directorsRupert Sutherland and Gerald Dickens, the continent was sculpted by two major tectonic events: The Great Divorce: First, it was torn from Australia and Antarctica 85 million years ago, stretching and thinning until it sank. The Resurrection of Subduction: About 50 million years ago, something “globally significant” happened. What scientists call a “massive subduction rupture” began, giving rise to the Pacific Ring of Fire. In simplified terms, this process caused huge portions of the seafloor to curve, parts of Zealand to temporarily rise above sea level, and then the continent to sink back more than a kilometer to its current configuration. It was not a local phenomenon. These tectonic forces altered the direction and speed of movement of many tectonic plates across the planet, in one of the largest geodynamic readjustments of the last 80 million years. Microfossils and the response of life. To reconstruct these movements with surgical precision, scientists they rely on benthic foraminifera. These single-celled shelled organisms are “diagnostics of the deep.” By analyzing its remains in the ship’s laboratories, researchers can determine whether a rock stratum belonged to a shallow beach or an abyssal plain. Furthermore, complementary technical studies, such as those presented in Paleoceanography and Paleoclimatology and marine Micropaleontologyanalyze the biotic response to hyperthermals (peaks of extreme heat). The results indicate that marine life does not react uniformly: the magnitude and speed of warming determine whether ecosystems adapt, reorganize or become stressed. These data are essential to improve predictive models of current climate change. A sea of ​​discoveries at risk. Zealandia’s exploration has shown that continents remain to be discovered and that the ocean floor holds the answers to the most pressing questions about our climate survival. However, science depends not only on curiosity, but on investment. Despite the scientific success of the 2017 expedition, there are countries that later do not intervene adequately due to lack of payments. This leaves future expeditions in the air that could continue to unravel the mysteries of this seventh submerged continent, a territory that, although hidden under thousands of meters of water, has a lot to say about the air we will breathe tomorrow.

Science explains why the cure can be worse than the disease

by

At the time of want to lose a few kilos The truth is that many different strategies emerge, such as eliminate sweetsstart exercising more or eat much more protein. But, on the other hand, there are strategies that are really extravagant and that are spread by influencers of our society that do not have any solid foundation. The last one arrives from actor Matt Damon who claims to have lost a few kilos thanks to leaving gluten out of his diet. A discrepancy. And the reality is that science has a lot to say about this decision. Since the ‘gluten-free’ foods that now flood supermarkets were born as a medical necessity for 1% of the population. But now it has become a holy grail of weight loss following the following logic: ‘if I cut out bread and pasta, I lose weight. Ergo, gluten makes you fat.’ There is no evidence. Nutritional science has bad news for these peopleincluding the actor, since eliminating gluten does not have a specific slimming effect. In fact, if you do not have celiac disease or gluten sensitivity diagnosed, eliminating it can even be counterproductive for cardiovascular and metabolic health. It’s a calorie deficit. The first myth to debunk is that gluten, per sebe a metabolic villain that makes us accumulate fat. According to a systematic review published in International Journal of Cardiovascular Sciencesgluten-free diets are not associated with greater weight loss compared to normal gluten-containing diets in healthy adults. So… why do some people swear they lost weight by giving up gluten? The answer lies in the changes that accompany this diet, but not in gluten. And when you give up gluten, you automatically stop eating calorie-dense ultra-processed foods such as industrial pastries, cookies, refined pasta… In this way, you eat fewer total calories and this is what causes you to lose weight and not the absence of gluten. The effect of water. In addition to this caloric deficit, a pilot study in athletes noted that the rapid weight loss after six weeks without gluten was primarily due to loss of fluid and glycogen stores, not an actual metabolic advantage. Fewer refined carbohydrates mean less water retention. But if there was any doubt, another clinical trial in patients with a metabolic problem in their history detected reductions in waist circumference and triglyceridesbut without changes in weight. In this way, the researchers suggest that this is due more to better food selection and glycemic control than to a “fat-removing effect” of gluten. A flat stomach. Another of the great thoughts that can be heard in this sense is that people who do not eat wheat feel much less bloated. And this is real, but the culprit is not gluten, but from the fructans of wheatwhich is basically a type of fermentable carbohydrate that produces a lot of gas and bloating. In this way, the abdomen looks much flatter, but not because of a loss of fat. The cardiovascular paradox. But although gluten is seen as a demon, the reality is that it has several intrinsically good things. For example, gluten is often accompanied by whole grains, and whole grains are cardioprotective. This is evidenced in a study published in the BMJ with more than 100,000 participants who were followed for 26 years. This concludes that gluten consumption does not increase the risk of coronary heart disease. What’s more, when the data was adjusted, a higher gluten intake was associated with a lower risk of coronary heart disease. That is why the authors warned: promoting gluten-free diets in healthy people can reduce the consumption of whole grains and, therefore, negatively affect cardiovascular health. And in diabetes. In this case they were three large studies that showed an inverse relationship: Those who ate the most gluten had a 13% lower risk of developing type 2 diabetes compared to those who ate the least. The why? Again, the fiber and micronutrients associated with the cereal that contains gluten. The problem of the accused. When we see that something is ‘gluten free’ we may think that we are looking at something much healthier. But the reality is that sometimes, to compensate for the lack of elasticity and texture that gluten provides, The food industry often reformulates products by adding more saturated fat, more sugar and reducing the protein it contains. Furthermore, gluten-free diets in non-celiac people have also been associated with a lower intake of fiber, B vitamins and a worse long-term cardiometabolic profile. Who should give up gluten? Science is quite clear in this case: who needs it, that is, the 1% of the population with celiac disease. And logically also people with non-celiac gluten sensitivity who may have major digestive problems. For the rest of the population, eliminating gluten offers no clear nutritional benefits. On the contrary: there is a risk of spending more money on products with a worse nutritional profile, reducing the consumption of cardioprotective fiber and attributing to gluten a success that, in reality, simply belongs to eating less ultra-processed foods.

China has turned the Arctic into its own “Panama Canal.” And that explains the US obsession with Greenland

by

It seems like it was centuries ago, but until not too long ago the Arctic was seen as an inhospitable territory, more associated with school maps and scientific expeditions than with great power disputes. However, accelerated thaw and the changes in routes navigation have turned that apparently marginal region into one of the most sensitive spaces on the geopolitical board, one where decisions made today can define the economic and military balance of the coming decades. Stop being peripheral. Yes, for decades, the Arctic was a space remote, frozen and secondary in global geopolitics, a natural border that separated blocks rather than connecting them, but accelerated thaw has transformed that white void into a strategic corridor where trade, resources and military deterrence overlap. What was once a physical boundary is now an emerging highway that shortens thousands of kilometers between Asia, Europe and North America, and that simple climate change is reordering strategic priorities of the great powers at a speed that has caught many governments off guard. China and the Polar Route. China has identified before anyone else the potential of these new routes and has integrated them into its long-term vision as a “Polar Silk Road”conceived as a functional equivalent to the Panama Canal or the Suez Canalbut under much more flexible conditions because the rules are not yet set. Chinese research vessels, experimental freighters and icebreakers they are already browsing through the High North, collecting oceanographic data, mapping seabeds and testing routes that reduce by half travel times between Asia and Europe, while establishing a presence that, as happened in the South China Sea, begins as scientific and commercial and ends up having inevitable military implications. Submarines, data and war under the ice. The most disturbing element for Washington and its allies is not only trade, but the underground: The Arctic Ocean offers ideal conditions for underwater warfare, with layers of water, variable salinity, and natural noise making sonar detection difficult. The dives of Chinese research submarines under the ice, together with the deployment of “civilian” vessels that in practice function as covert military platforms, point to a clear objective: break the historic American submarine superiority and prepare the ground so that, in the future, Chinese nuclear submarines can operate near the North American continent with greater freedom and less risk. The Sino-Russian alliance. Chinese expansion in the Arctic is amplified by its understanding with Russiawhich provides experience, technology and access to already exploited routes along its northern coast, while receiving in return key industrial and technological support to sustain its war in Ukraine. This axis turns the Arctic into a space where two nuclear powers They coordinate in their own way air, naval and potentially submarine patrols, opening the door to a scenario that was unthinkable during the Cold War: Asian forces with the capacity to rapidly project themselves towards the Atlantic without passing through easily monitored bottlenecks. Greenland as a hinge. In this context, Greenland stops being a frozen and sparsely populated island and become the hinge that controls the eastern flank of the Northwest Passage, the gateway from Europe to that future Arctic highway. Whoever has decisive influence over Greenland can monitor, condition or even block maritime and submarine traffic in one of the most sensitive routes of the 21st century, in addition to housing radars, airports and key sensors for the defense of the American continent. The emergencies. Here comes the Trump’s renewed interest to take over Greenland, which does not respond to an eccentricity or a nineteenth-century imperial impulse, but rather to the recognition of an emerging strategic vulnerability. Washington watches how Beijing advances in the Arctic the same way he did in other settings: arriving early, coming to the table when the rules do not yet exist, and securing positions which then become almost impossible to reverse, which explains the pressure on Denmark, the enlargement of icebreaking capabilities and closer integration of the High North into NATO planning. No locks. In summary, and unlike the Panama Canal, the Arctic is not a closed infrastructure nor regulated by consolidated treaties, but rather a space under construction where the early presence defines future power. For the United States to allow China to consolidate a dominant position on these routes would be to accept that its geographic and naval advantage can be eroded without a single shot, simply by letting the ice melt and others write the rules. Greenland thus appears as the last piece of a bigger puzzle: one where it is not about buying or invading an island, but about deciding who controls trafficsecurity and the balance of power in the next great axis of global trade and war.

Neuroscience explains why the brain takes much longer to mature than we thought

by

The idea we have about adolescence right now it ends at 25 years old, this being the age at which supposedly the brain has just been ‘cooked’ forever to give way to a functional adult. But the reality is very different as the new studies point out, since we would continue to mature the brain until at least 32 years old. Where did the current idea come from? To understand why scientists pointed to 25 years as the age at which brain maturity ends, we must go back to studies of the past. Specifically to Resonance studies from the 90s and early 2000s like the classic Nitin Gogtay who mapped brain development and discovered that the cortex matures from “back to front.” This means that the sensory and motor areas are consolidated soon, but the prefrontal cortex which is in charge of executive functions, impulse control and planning is last in line. The problem is that many of those studies stopped following the subjects when you reach 20 or 21 years oldsince seeing that the curve continued to rise, it was assumed that the “peak” of maturity would arrive shortly after, around the mid-20s. But we had no idea what happened after this. Just assumptions. A new frontier. In order to solve this ‘blindness’ of neuroscience used the analysis of more than 4,000 brains using connectivity neuroimaging techniques at the University of Cambridge. What they saw was clearly five ‘epochs’ or milestones in brain wiring throughout life. Different turning points. And as if our life were a game, in the brain we have like five different screens that begin at a specific age that acts as a turning point. These ages are: 9, 32, 66 and 83 years. What interests us in this case is the period between 9 and 32 years, since the brain is characterized by a continuous increase in the efficiency and integration of neural networks. It is what the authors describe as an ‘extended adolescence’. It’s not that at 30 you think the same as a 15-year-old, but that the architecture of connections has not yet reached its final ‘adult’ form. Something that occurs at age 32 and remains stable until age 66, when brain activity begins to decline. To understand it better. Researchers wanted to use a simile to illustrate this new paradigm. To do this, they ask us to think of our brain as the union of several “functional neighborhoods” that specialize in specific tasks such as vision, language or logic. All of these are integrated with each other through different highways that are high-speed connections. Well then, between 20 and 32 years old The brain is balancing these two processes, so that the connections between different areas of the brain are well connected and organized. And it is precisely this typical pattern of the adult network, where the brain is capable of integrating complex information fluidly, which does not appear until after the age of thirty. Teenager at 30? This is where the important nuance comes in. Just because the brain continues to mature structurally does not mean that we should redefine adolescence in legal or clinical terms. All this because maturation is a gradient, not a switch of ‘now I’m a teenager and now I’m not’. To understand this, you have to know that the different elements of the brain and executive functions have a very different development curve. In this way, saying that the brain matures at 32 is a simplification that is as useful (or as erroneous) as saying that it matures at 25. What science really tells us is that there is no sudden development “blackout”; We remain biologically plastic and dynamic much longer than we thought. An opportunity for habits. This prolonged maturation is good news for all of us, since if the brain continues to actively ‘wire’ itself throughout our 20s, it means that structural plasticity is especially dynamic at this stage. In this way, science is quite clear: aerobic exercise, learning new languages ​​or facing cognitively demanding tasks during this “third decade” of life helps to improve the volume and organization of the brain’s white matter. On the contrary, factors such as chronic stress can affect the integrity of those connections. In short, a brain at 28 years old is not a finished product, but rather a work in progress that is finishing paving its best highways. The next time someone tells you that you should have your life figured out now because “you’re an adult,” you can tell them that, according to the University of Cambridge, your brain still has a couple of years of baking left.

A geologist explains why natural disasters continue to surprise us

by

How can an eruption on the other side of the planet cause a “year without a summer”? Why does an apparently small earthquake devastate a city while a larger one goes almost unnoticed? The answer is not always in magnitude of the phenomenon, but in the place where it occurs, in the number of people exposed and in how the risk is managed. Understanding it is not just a scientific question: it is a way of looking at the planet with different eyes. ‘Science and aside’ It is the space where we talk about science with experts. It is part of our YouTube channel and is also available as a podcast on Spotify and iVoox. In her fourth episode, Ángela Blanco interviews Rosa María Mateosgeologist and director of the Geological and Mining Institute of Spain (IGME-CSIC), a reference voice in the study of natural disasters. With decades of experience and a doctorate focused on this field, his vision helps us understand what is happening on Earth. When science faces the fury of the planet The conversation starts with a seemingly simple question: what is the most damaging natural disaster? The interviewee responds calmly: “It depends where you are and where you live.“In his explanation there are no hierarchies between volcanoes, earthquakes or tsunamis, but nuances. “Living in the Canary Islands, which has a high probability of a volcanic eruption, is not the same as living in Madrid, where the probability is zero.” The danger changes with the map, and understanding it requires looking at the geology of each place before its history. “Among the great episodes that marked the history of the Earth, Rosa cites one that was on the verge of erasing our species from the map. “We are talking about 74,000 years ago, which probably was on the verge of ending the Homo sapienswith our species.” It refers to the eruption of the Toba volcano, a megaeruption in Indonesia. Rosa explains that not all earthquakes are measured the same and that their magnitude can be misleading if you do not understand how it is calculated. “The magnitude of the earthquakes It is measured on a logarithmic scaleto. This means that an earthquake of magnitude four is not twice as strong as one of magnitude two.” The difference, he clarifies, is exponential: each point on the scale multiplies the energy released, and that is enough to turn an earthquake into a colossal force. Some historical episodes demonstrate this better than any graph. Rosa remembers the Lisbon earthquake of 1755 not only for its magnitude, but for what it represented for science. “The waves reached the coasts of Finland.” The phrase summarizes the scope of a phenomenon that destroyed the Portuguese capital and left traces throughout the Atlantic. From that disaster a different way of thinking was born. To understand why some catastrophes are devastating and others are barely mentioned, the expert introduces an essential distinction. “We geologists talk about two very different concepts that we often confuse. One is the danger… and another thing is the risk.“In the video he explains what each one consists of, their scope and also the consequences of confusing the terms. The conversation with Rosa María Mateos shows that natural phenomena cannot be avoided, but their effects can be reduced. In this episode of Science and apartthe geologist explains how observation and knowledge help to anticipate risks and live better with them. A talk that leaves open the door to continue learning about the planet we inhabit.

Science explains why coriander knows you soap (and the fault belongs to your genes)

by

For many it is a touch of indispensable citrus freshness in tacos, guacamoles and curris. For others, it is a culinary abomination that It ruins any dish with a disgusting soap flavormetal or even insects. The coriander is undoubtedly one of the most polarizing herbs in the world, an ingredient that does not admit average terms and has generated much frustration. It is not a matter of taste. For years, science has investigated this phenomenon and the answer is clear: if the coriander knows you soap, it is not being a fussy: The fault, in large part, has your DNA. The “soap gene” exposed. The key piece of this genetic puzzle found it An association study at a genomic scale (GWAS) published in the magazine Flavour. Researchers analyzed the DNA of almost 30,000 people and found a direct connection between the perception of coriander soap and a specific genetic variant. The main suspect is a unique nucleotide polymorphism (SNP) known as RS72921001. This small change in the genetic code is found on chromosome 11, just in the middle of a group of olfactory receptor genes. And one of them, called OR6A2, is the perfect candidate to explain the mystery. Because? The OR6A2 gene encodes a receiver in our nose that is especially sensitive to aldehydeschemical compounds that are key components in the aroma of coriander. Interestingly, these same aldehydes are also a byproduct of the soap manufacturing process and are secreted by certain insects as a defense mechanism. In essence, people with this genetic variant have a kind of “antenna” superpotent for the aldehydes of the coriander. While a person without this variant perceives a fresh and herbal aroma, someone with the variable of the O6A2 gene receives an overwhelming sign that his brain interprets with the taste of soap. A more complex genetic cocktail. Although the O6A2 gene is the protagonist, the story does not end there. Another study conducted with twins by the Monell Chemical Sensa Center, and published in Chemical Sensaadd more nuances to the equation. This investigation not only confirmed that coriander aversion has a strong hereditary component – stating the inheritability of taste for coriander in 52% – but also identified other genes involved. Specifically, there have been three genes that have identified in this genetic combo. The first one is TRPA1 which is known for detecting spicy substances, the second is GNAT3 which is crucial for the transduction of signs of taste in the language. The last is the TAS2R50 That is a receptor of bitter taste. This suggests that, for some people, the rejection of coriander is not only due to a soap smell, but to a complete sensory experience that may include bitter notes and a sense of unpleasant itching or flavor. The geography of flavor. Genetics is closely linked to offspring, and coriander aversion is no exception. Statistics demonstrate a fascinating global division, as revealed by a study by the University of Toronto. The prevalence of coriander aversion change dramatically between different ethnocultural groupsaccording to these proportions: Oriental Asians: 21% Caucasics: 17% Afro -descendants: 14% South Asians: 7% Hispanics: 4% Middle East: 3% These percentages make a lot of sense. These data are not casual. Populations with less aversion are those in whose kitchensh It has been a pillar for centuries, such as Mexican, India, Thai or the Middle East. This raises an interesting evolutionary question: was the kitchen of these regions adapted to a population that genetically enjoyed coriander, or constant exposure for generations helped overcome an initial aversion? The answer is probably a mixture of both. How to learn to love coriander. While your DNA predisposes you to hate the coriander, it is not necessarily a judgment of life. Inheritability, although significant, is not 100%, which means that environmental factors and exposure play an important role. Experts suggest that it is possible to “train” the brain to accept, and even enjoy the coriander. Some of the tricks they give is to crust the coriander in the form of pesto or sauce so that the soapy aldehydes are diluted. But you can also bet on introducing it little by little and mixing it with other powerful flavors so that the palate can get used to it.

Many heterosexual women say they are fed up with men. There is a theory that explains it: “heterofatalism”

by

In a city like New York – or Madrid, or Buenos Aires, or any city where a woman with quotes history and good Internet connection reevalu Spin-off Less glamorous of Sex and the city. One where the stories do not end in Manolo shoes and kisses in the rain, but in Ghostingsexcuses for anxiety and group therapy in dinner format. And it is not that Carrie Bradshaw did not warn something similar. In more than one episode, their columns revolved around a question today very close to what many women formulate from a more critical and collective place: heterofatalism. A term that describes the disenchantment, irony and resignation with which their love experiences with men look at. But it is a ismIs it a theory or just another bad appointment with academic name? Heteropesyism It was coined in 2019 By the columnist ASA beings, describes an attitude of hopelessness and resignation to heterosexual relations, especially from the perspective of women who, although disappointed, do not abandon those relationships. As He explained an article in The Conversationthis position “does not necessarily imply violence or hierarchies”, but rather “a worldly but persistent disappointment.” However, beings propose a more extreme version: heterofatalisma kind of resigned acceptance of heterosexual failure. As explained by Jean Garnett In an extensive article for The New York Timesis “the feeling that the men I want do not love me with enough clarity, urgency or commitment.” An amplified term There is a political and social context that exacerbates disenchantment. As Marie Solis points out in The New York Timesmany of these speeches intensified after the choice of Donald Trump and the confirmation of Brett Kavanaugh, perceived figures as symbols of sexist impunity. The #MeToo Movement, Although transformativedid not change the most daily dynamics of the appointments. In addition, social networks have amplified this narrative. Tags like #boysober, #selfpartnered or growing interest In movements like 4b (Rejection of relationships, sex, marriage and maternity with men) portray a generation of women who, although they do not always renounce men, have lost faith in the promises of heterosexual love. According to sexual Health Alliancethis gap is linked to how men have been socialized: with difficulty verbalizing emotions, Fear of vulnerabilityand in some cases, a rigid masculinity that associates desire with domination or detachment. Professor Ellie Anderson Talk about “hermeneutical work”a form of emotional exploitation in which women are responsible for interpreting the confusing signs of little communicative men. It also mentions the “masculine regulatory Alexitimia”, a structural emotional difficulty in many heterosexual men. For her part, the psychoanalyst Jessica Benjamin Talk about the “paralyzing complementarity”: When both parties in a relationship feel that they cannot gain recognition without losing power. All this composes an emotional scenario where, as Ironiza Garnett“A woman asks for clarity and is punished for ‘being too intense.” In a Newtral article, the journalist Noemí López Trujillo Lo has explained quite clearly: Connect the rise of heteropesis with a stretch of female sadness. Speaks of Femcelcore As a cultural current where women are portrayed as broken creatures, dressed in black and away from men as the only self -protection strategy. This romantization of the love duel, however, can fall into a sterile nihilism, which avoids all political or transformative action. ORna exclusively feminine experience? Although heterofatalism has been mainly theorized since the experience of heterosexual women, some authors warn that it is not completely unilateral. The Times points out that While women express this pessimism with irony and memes, heterosexual men are also experiencing a crisis, although with very different consequences. While they retract, they take refuge in communities Like incels or PERICAderiving his frustration in misogyny. In this context, in recent years the proliferation of male communities that feed a growing anxiety towards relationships and a replication towards the idea of “traditional love” has become more evident: stable couples under rigid gender roles, and a nostalgia for an alleged “golden age” – the 50s and 60s— 60— in which, with a single salary, “the woman stayed at home, they had three children and they were all happy.” This imaginary, reinforced by online forums and conservative speeches, Not only does it idealize an unequal pastbut it presents it as a remedy against current confusion and disenchantment. For her part, the Poppy Sowerby journalist, In The Timeshe warns that when women hold all men for their disappointment, without nuances, heterofatalism becomes the reverse of the Incel discourse. In both cases, the heterosexual relationship is presented as a tragic destination and without exit. There is a disjunctive present in this whole situation: is the desire the problem or the roles that frame it? One of the most relevant criticism of heterofatalism comes from within feminism. As Health Alliance has detailed sexualthis speech can end up naturalizing misogyny by equating it directly with heterosexuality. The problem, they argue, are not the men per se, but the gender roles that both – men and women – reproduce without questioning. Rachel Connolly, In The Guardianhe sees heteropessimism as “a conservative vision disguised as radical criticism.” Really all we can expect is that our partners do not throw their dirty socks? What kind of imagination do we have if we assume that heterosexual relationships are convicted by nature? Shon Faye, In his book Love in exileproposes something different: stop waiting for a couple to be everything. It raises a reorganization of relationships based on the recognition of our diverse needs –sex, conversation, care, finance – as potentially distributable, and not necessarily contained in a single romantic link. In short, the panorama that is presented is ambiguous. On the one hand, there is a growing awareness of the failed dynamics of heterosexual love. On the other, there is a scarce exploration of real alternatives. The challenge, According to Jessica BenjaminIt is not the resignation, but the encounter. To do this, it proposes the concept of “intersubjective third”: a mutual recognition zone where both parties are seen as subjects with desire, agency and vulnerability. It is … Read more

A Netscape decision in the 90s explains why Google and Meta grow up with each technological revolution

by

In 1995, engineers of Netscape They faced a problem during a development night: how to allow websites to execute code without being able to steal user data? Thirty years later, its solution, the ‘Same-Origin Policy‘(Policy of the same origin), has become the invisible architecture that governs all the Internet. Why is it important. Each website became an isolated universe, unable to communicate with others. That night decision explains why we can barely escape the Apple ecosystem, why our data live trapped in silos and why each technological revolution makes the usual giants more powerful. The context. Alex Komoroske, former strategy director in Stripe and former director of Google for 13 years, He has identified what he calls the “iron triangle” of modern software. System designers can only combine two of these three elements: Sensitive data. Internet access. And non -reliable code. The logic is simple: if you allow unknown code to access personal data and have Internet connection, you can steal everything and send it anywhere. The solution was the total isolation. Each application became a fortress where your Instagram data cannot talk to Uber’s, your Apple photos cannot be processed by Google tools, and each service begins knowing zero about you. In detail. Komoroske Talk about this phenomenon With the water metaphor going down a mountain. Each obstacle does not stop the flow, redirects it where there is less resistance. Over time, channels are formed that attract more water to become increasingly large rivers. Planning a trip illustrates this mechanism: Flights in the mail. Hotel in another app. Restaurants in Google Docs. Calendar in a different tool. The constant friction of copying, pasteing and reformating leads to grant access to a single service that already knows all your context. Without friction, everything works perfect. When you share the trip, you use the tool that already has all the information. The threat. The AI promises to be different, but is inheriting the same physics. The LLMS They can create almost free software – a developer with AI can build in hours what it took weeks – allowing infinitely personalized tools. But this “infinite software” distributed through traditional stores does not solve our problems: it amplifies them. More applications mean more silos, more places where your data is trapped. The AI needs context to be useful, but our current security model means that sharing context is a commitment of all or nothing. Yes, but. The technical pieces to transcend this paradigm already exist. Modern Intel, AMD and ARM chips include “safe enclaves“, encrypted and protected memory regions of anyone, including cloud administrators. AI brings us a unique opportunity, because it makes the current limitation evident. The technical pieces already exist and it is the first time in thirty years that we can transcend this policy. While nothing changes, the concentration of power will continue to reinforce.
