ice

8 kilometers of ice have been lost in two months and researchers only agree on one thing: it is something to worry about

by

Predict their future the antarctic glaciers It is undoubtedly a great challenge for science, but the most important thing above all is to know How will it affect global sea level?. The worst of all is that the latest news we have at our disposal is not at all positive, since the Hektoria glacier It has retreated 8 km in just two months, which is an unprecedented speed in the modern era. Where we start from. Normally, the retreat of glaciers It is measured in hundreds of meters per year. It is one of the clearest metrics we have to be able to ‘measure’ global warming, and that is why now what a team from the University of Colorado Boulder has just recorded on the Hektoria glacier, on the eastern peninsula of Antarctica, plays in a completely different league. The measurement. In just two months during 2023, the Hektoria lost almost half of its mass. In total, 8 kilometers of ice disappeared. A speed of collapse that has never been seen in modern history and that, according to the authors of the study, is more typical of the end of the last ice age. Something that doesn’t add up in this case. Hektoria is relatively small by Antarctic standards (about 300 km², less than the city of Malaga), but its collapse was so sudden that it left researchers stunned. A coincidence. Ironically, the research team wasn’t even studying Hektoria. They were analyzing satellite and remote sensing data for another project when Ochwat realized that the glacier had essentially disappeared from the images. The measurements. This is where technology comes into play. The team had to combine data from multiple satellites to understand what had happened and, above all, how quickly he did it. “If we only had one image every three months, we couldn’t say that the glacier lost two and a half kilometers in two days,” explains Ochwat. In this case, by combining images from different satellites you can fill in the time gaps and confirm with evidence in hand how quickly the ice has been melting. But the key was not only in the images. They also used seismic instruments that have the ability to detect a series of “glacial earthquakes” that occurred exactly during the period of rapid melting. And these earthquakes are not measured for the sake of it, but to confirm something crucial: the glacier was anchored to the bedrock (and not floating) just before breaking. This is fundamental both for science and for the entire planet, since ice that is floating (such as an ice shelf) does not raise sea level when it melts, any more than an ice cube does in a glass of water. But ice that rests on land (or anchored to a seabed) and falls into the sea does contribute to the global rise in sea level by increasing its volume. Your Achilles heel. The collapse was not due to simple superficial melting. The cause was topographic, since many Antarctic glaciers rest on deep canyons or underwater mountains. The Hektoria, however, had the misfortune of resting on an “ice plain”: an area of ​​bedrock that was exceptionally flat and below sea level. This flat topography caused a gigantic section of the glacier to begin floating all at once, rather than gradually. The moment the glacier lost its anchorage to the ground (its “line of support”), it was exposed to the forces of the ocean, and therefore everything began to advance very quickly. The process was brutal, since it all began with the warmest ocean water that seeped underneath and began to open cracks from the bottom of the glacier upwards. At the same time, the glacier already had cracks on the surface. Eventually, the lower and upper cracks met and the glacier literally disintegrated. A warning for future glaciers. The Hektoria case is a first-rate warning. Scientists know that there are numerous glaciers in Antarctica that also rest on these types of ice plains. Until now, it was thought that their collapses would be centuries-long processes. Hektoria shows that they can be months, which should set us off due to the implications it would have on sea level. And while the collapse of a small glacier like Hektoria won’t dramatically change global sea level, it alone does demonstrate that a rapid collapse mechanism, until now theoretical or believed to be typical of past geological eras, is perfectly possible today. If this same mechanism is activated in much larger glaciers, sea level rise could accelerate very considerably and much sooner than expected.

110 years later we finally know what sank the ‘endurance’ in the Antarctic. The culprit was not the ice: it was much worse

by

He Endurancethe legendary ship of Ernest Shackletonbecame a symbol of resistance and heroism after its sinking in the icy waters of the Weddell Sea in 1915. There began the myth, because during more than a centuryits end was wrapped in a halo of mystery, attributed to the lethal coup of the ice against its rudder. Now, science He has revealed That the truth was more complex and, in a way, disturbing: the ship was never prepared to survive. The myth and the truth. As we said, for more than a century, 110 years to be exact, Ernest Shackleton’s heroic story and his antarctic ice crew was accompanied by the conviction that the endurance was the wooden ship more robust of his timevictim of a fatal blow of the ice against his helm. However, Recent research They have dismantled that narrative. The thorough analysis of the wreck discovered in 2022 reveals that the ship I was convicted From the beginning: it was not a single impact that sank it, but the accumulation of compressive forces that crushed their weak structure and, very important in the final story, Shackleton I probably knew When he left for Weddell. The expedition trapped. Endurance sailed in 1914 with the ambitious plan of cross the Antarctica on footbut at the beginning of 1915 he was caught in a solid ice. For ten months the crew resisted on board until the pressures began to deform the ship. The covers were combined, the helmet vibrated with a crash and the newspapers of the sailors picked up the sound of the creak of the wood under huge forces. On October 27, 1915 Shackleton ordered to leave the shipand weeks later the helmet ended up sinking after a succession of pressure onslaught that started masts and opened the structure in two. Idealized cross sections of the first Antarctic ships. The endurance was of the type (a); The type Deutschland (B) Fortress with mud feet. Far from being the invulnerable ship of the legend, the endurance was born as a ship of Polar and Hunting Tourism of bears and morsas in the Arctic. Its design lacked the critical reinforcements to survive trapped in an icy sea: it had no diagonal beams that kept the bands of the helmet or racks that supported the machine room, its most fragile area. Over there, According to witnesses As the scientist Reginald James or Captain Frank Worsley, the iron plates combined and the soils bulging while the ice pressed incessantly. The Rudder and the keel departed, but they were not the cause but the consequence of that structural weakness. Pecio discovered in 2022 Shackleton knew it. It is one of the keys that light has seen now. The most revealing thing is that Shackleton I did not ignore Those defects. He had participated in rescues from other ships shattered by ice and advised the German Wilhelm Filchner reinforce with diagonal beams Your Deutschlandthat thus managed to survive eight months trapped. Even in a letter to his wife he admitted that the endurance was not as solid as The Nimrodthe ship of your previous expedition. Even so, He acquired it Without modifications, moved by the urgency of undertaking a colossal project in the midst of their debts, their personal failures and competition with other explorers for reaching Antarctic glory. The re -written history. He New study of Jukka Tuhkuri Disassemble the myth of the invulnerability of the endurance, showing that it was an inappropriate ship faced with a relentless environment. However, this finding does not decrease the figure of Shackleton, but it frames it With more realism: A leader who risked aware that the adventure could cost the ship, but that miraculously saved his entire crew. At a time when polar exploration was a jump of faith towards the unknown, the wreck of the endurance was not only the end of a ship, but the proof that even the stronger wood yields Before ice pressurewhile human will manages to survive where the technique fails. Shared destination. The truth is that the Endurance drama It was not an isolated episode. Decades earlier, in 1876, twelve American whales They sank in front of Alaska for lacking the necessary reinforcements against compressed ice, dragging with him the livelihood of hundreds of families. Something similar happened in 1903 with The Antarctica Swedish ship trapped and shattered in the Weddell Sea. And, in contrast, the case of Deutschland It demonstrates how simple modifications could make the difference between sinking and survival. If you want also, all these episodes draw a pattern: polar ice does not forgive improvisations or risk economies. Shackleton, with his leadership instinct, achieved what other captains They did not achieve: save all his men, although at the expense of expose them to sacrifice of a ship that had never had to face the brutality of the white continent.

Scientists have folded salty ice and discovered that it behaves like an electric generator

by

When we think of ice and salt, it is normal to imagine a road in the middle of winter: the accumulated snow on the asphalt, the trucks spreading salt in a hurry and the neighbors trying not to slip on the icy sidewalks. It is a typical scene in the north or in the mountain areas, where winter turns the landscape into postcard, but also a daily challenge for those who have to move between cut roads or pedestrian crossings turned into traps. What we usually see how a simple help against ice on roads, can actually hide an energy potential. A team from the University of Xi’an Jiaotong, in collaboration with ICN2 and Stony Brook University, has managed to try it in the laboratory. A discovery with “taste” to salt. A pinch of salt for a material to deform, produce electricity. This phenomenon has a name and is called flexoelectricity. It had already been observed in moving glaciers or in ice plates under pressure, but never with results as powerful as those achieved in this study. According to the studythe team frozen water with different concentrations of common salt (NaCl) and created ice blocks in several ways: cones, beams and plates. Then they applied flexion tests – check the ice on two supports and exert pressure from above – and measured the electricity generated. The result was surprising: salty ice generated up to 1,000 times more electric charge than pure ice. The key ingredient. But how can salt enhance something as inert as ice? The answer is in the salted water microchannels that are trapped between the crystals. As the ICN2 press release detailssalt prevents ice from freezing. When folding, water and salt ions move from compressed areas to the stretched, generating an electric charge flow, what scientists call a “Current streaming”(Drag current). In practical terms, the effect is so strong that experimental devices reached values ​​comparable to the best piezoelectric materials used today in the industry, According to research. Depend on ice. At first glance, this technology could have applications in extreme environments, such as scientific stations in polar regions, where installing conventional energy infrastructures is very difficult. The finding contrasts with reality. Since 2000, glaciers have lost 273,000 million tons of water annually, According to ESA. That is equivalent to the consumption of the entire world population for three decades. The setback is already translates into a loss of 5% of the global ice volume, with visible consequences: increased sea level and less availability of fresh water in rivers such as Ebro. Thus, to talk about ice as an energy resource raises an uncomfortable paradox: depending on something that melts increasingly faster. That’s not all. Beyond the environmental dilemmas, the study itself recognizes that there is still much to solve. As they point out in Techxploresalty ice devices suffer mechanical fatigue: after many flexion cycles, their ability to generate energy can fall to 80%. In addition, much of energy is lost in the form of heat, which makes efficiency still lower than that of commercial piezoelectric devices. The look is wide. Even so, the finding opens a fascinating door. “Its advantages – abundance, sustainability and low cost – make it a promising candidate for clean technologies,” Underline the ICN2. And researchers believe that the model is not limited to ice: it could be applied to other porous solids containing fluids inside. The paradox, however, persists: while science explores how to take advantage of the hidden energy on ice, climate change melts at an alarming pace. Perhaps this discovery not only serves to think about new technologies, but also to remember the value of a resource that is disappearing.

So much ice has melted in Greenland that the plankton has grown 40%. It is not good news

by

The Antarctica and Greenland have become two of the Climate change thermometers. The Ice loss in Greenland It is something that has been monitored for years because not only influences sea level: also in the Sinking of the seabed. It is estimated that Greenland’s glaciers have reached a point of no returnand its implications go beyond sea level. In fact, a recent NASA study He points out that there is a beneficiary of the thaw: the phytoplankton. And it is not good news. Short. A few months ago we commented that Greenland was getting greener. The estimates point out that, during the last 30 years, the region has lost 1.6% of its ice, which may seem little, but it is something equivalent to the Galicia area. The air temperature is about 3 higher Celsius degrees in the period between 2007-2012 than in 1979-2000, and That thaw It is causing a huge increase in fresh water. How much? According to the investigation of San José State University and NASA, of up to 266 million tons per year that are discharged into the sea, especially under the Jakobshavn glacier, the greatest in Greenland. It is the equivalent of 1,200 cubic meters of fresh water that are poured into the sea every second. As is fresh water, it is less dense and lighter than the salty, and what it does is like a whirlpool, dragging nutrients from the seabed to the surface. The study. These nutrients are mainly iron and nitrates, and it is phenomenal to phytoplankton. It is, however, an anomaly, and the researchers wondered to what extent that rapid growth of the plankton could affect the ecosystem. In it studypublished in Nature, detail how with the help of a model developed in the JPL and the MIT and using superoringers to accelerate the calculations, simulated the interaction between the water of the thaw, the nutrients and the phytoplankton. The greatest areas is where an increase in chlorophyll has been seen in recent years They have discovered that the growth of the body in the studied area increases between 15% and 40% in summer, at which time the maximum point of the thaw is given, thanks to those nutrients that the fresh water current sends to the surface. In total, NASA has observed That, between 1998 and 2018, the growth of phytoplankton in argic waters had increased by 57%. Consequences. On the one hand, that increase in phytoplankton can be positive for marine life, since it improves the basis of the ecosystem to be able to feed more animals, and also phytoplankton Atmospheric co -capture (that is not bad for us) To do photosynthesis. However, there is a paste: changes in temperature, chemical composition and water salinity can alter ecosystems. In the study they have not launched predictions about what will happen, but it is evident that it is a substantial modification of the marine properties of that specific area. Its conclusion is that those Changes in the Food Chain They can modify the composition of marine species, from bacteria to fish, affecting both the equilibrium of the ecosystem and fishing activities, which are a key engine for Greenland. Because phytoplankton is tiny, but it is the food of Kril and other small herbivores that, in turn, are the larger animal food baselike fish and whales. Only in Greenland? This study was carried out in a very specific area, that of the Jakobshavn glacier, but the results have similar implications for the more than 250 marine glaciers in the region and, possibly, for other glaciers that end in the sea in other regions of the world. Researchers comment that this simulation method is adaptable to other systems and that, therefore, it is likely that other areas where glaciers are pouring water into the sea They are also living, to a greater or lesser degree, a similar phenomenon, modifying ecosystems and affecting both fauna and fishing activities that are carried out in the area. Therefore, the thaw of glaciers is no longer that it affects only at sea level, but has the potential for alter the ecological balance of the regions in which it occurs. As they say, we were few and the grandmother gave birth. Images | POT In Xataka | 400,000 years ago all Greenland ice melted. The map he drew is not flattering

There are people freezing mandarins and clementines to eat them later as a “ice cream”

by

In one of the many viral videos that can be making a Scroll Fast in social networks, a young woman a frozen cucumber is passed by the face with the solemnity of who applies a luxury mask. It seems absurd, but the clip accumulates thousands of “like.” It is not an isolated case: in networks, frozen foods have become homemade cosmetics, visual snacks and even summer rituals. This year, a new trend makes its way with force: freezing fruits, and especially Clementines. The goal is not to keep them for later, but enjoy them in their most refreshing and surprising version. A citrus explosion. The phenomenon, baptized by some like the “Frozen Clementine Hack”, became popular after the video by creator Hannah Rose, who already exceeds 10 million views on Instagram. The procedure is simple: freezing clementines, passing them under hot water for a few seconds and cutting them in half. The result is small frozen segments that easily detach from the skin, ready to eat as if they were natural jelly. As They have detailed in a Food & Wine reportattractiveness goes beyond flavor: crunchy texture, the sound when bite and the star pattern that appears when cutting the fruit contributes to a complete sensory experience, ideal for sharing in networks. Is it another posture sample? Beyond the visual impact, the truth is that there is a logic behind this viral gesture. Fruit fruits is not new, but some lend themselves better than others. Clementines, for example, have less free water than other fruits, which reduces the risk of large ice crystals that break its structure. According to My partner explained in this media“The more water a food has, the more its structure is altered when freezing.” Hence, the defrosted lettuce is soft and watery, while small and firm fruits such as mandarins, or starch vegetables such as peas, support the process much better. Is it healthy? In principle, freezing clementines is perfectly safe and healthy, provided that minimal precautions are followed. The ideal is to consume them directly frozen or fresh from the cold, avoiding leaving them at room temperature too long. At a nutritional level, most important compounds – fibra, minerals, proteins and fat -soluble vitamins – remain stable in the freezer. Yes indeed, As we have explained in this mediumsome hydrosoluble vitamins such as C can decrease during the defrosting process. In other words: it is not a miraculous way of consuming fruit, but it does not have relevant inconveniences. And if that helps more people eat fruit in summer, maybe I have already fulfilled its purpose. Opening the door to other fruits. As they have pointed out In Food & Winefrozen grapes, for example, They have been a typical snack for some time In summer. The mango in Frozen cubes It is ideal for soft milkshakes or ice cream. And the watermelon, although it is not recommended to defrost to eat raw, it works well if it is consumed directly crushed as graniza. The summer fruit. What began as one more curiosity in Tiktok has ended up consolidating itself as a summer habit with some scientific support. Beyond the filter and the sound effect, freezing fruit – especially the one that tolerates it well – can be an accessible and attractive way of maintaining healthy habits even In full heat wave.

In full birth crisis, the ice cream industry has found a new reef in Spain: dogs

by

No, it’s not yours. For a long time in the parks of Spain (and in the streets, squares, shopping centers and thus a long etcetera of places) it is easier to find pets than with babies. Some calculations They point out that in our country there are already six companion animals for each child under four years. Hence the sector dedicated to your care be growing and tante new business roads, such as Cruises canines or the elaboration of ice cream and “Cafes” Suitable for dogs. In Barcelona there are already a few examples. Pet ice cream? That’s how it is. And we don’t talk about ice cream for pets suitable for pets, but ice cream specifically elaborated For dogs and cats, thinking about the foods that tolerate and advertise as such. One of the most recent examples leaves it Zampa Gelatothat He just launched In Barcelona Tarrinas that are announced with A slogan that leaves a few doubts about his approach: “The ice cream one hundred percent natural that makes your pet happy and veterinarian.” In its catalog it includes watermelon options and red fruits, apple, pear and kiwi or coconut, pineapple and banana, elaborate ice cream, says, based on pasteurized yogurt without lactose without lactose, lyophilized and mineral fruits. “It is not another product within a range, it is our specialization. Zampa Gelato focuses exclusively on developing healthy pets for pets,” They claim From the firm. Is it an isolated case? Not at all. The pet ice cream market is perhaps still far from the centered in humans, but there are more examples. Bibì e Bibò ice cream shops, with a presence in Madrid, have created a Special line “100% suitable for dogs” that elaborates, among other ingredientswith several fruits, ill -free yogurt without lactose and dispensing with added sugars. The newspaper of Catalonia Precise also that one of the partners who has embarked on the launch of Zampa in Barcelona is in turn part of the team behind Il Gelato Dell´amorea “Mixed ice cream shop” which boasts of having ice cream for both humans and their four -legged companions. They are just a couple of examples, but there is more. Now A couple years Barcelona’s Badiani ice cream shop also elaborated a GELATO For dogs. They called him Dog Gelato and in 2023 the magazine Elle I presented it as a sweet refreshing with 96.65% less lactose than the rest of its ice cream and basically made with whipped cream, egg yolk, plant fibers, water, fructose and whole milk and low dust in lactose. In 2024, to give him More visibilityBadiani launched a campaign that offered customers a portrait with their pets. But … why? Basically because there are interested owners and especially willing to pay for those services. “Given the growth and demand of premises Pet-Friendly We did a small market study, “said Nebot recently to The newspaper. “The acceptance by the clients was fulminant. The idea is to go out for something with your pet and that is not under the table sucking an ice or waiting for the last piece of cookie of your ice cream.” As a reference last year Il Gelato Dell´amore sold More than a thousand tarrines Canines in August. Are there only ice cream? No. ice cream are just one more example (perhaps the most summery) of the growing range of pet products and services. The list is wide and includes articles that we so far believed exclusive for humans, such as “coffees”, “cocktails”, “snacks” or even “champagne benjamines”. All this with proper quotes because these are products designed for dogs that play with recognizable formats in the market for their owners. The Ciudad Ciudad has just left another good example. Not long ago opened its doors there Voilà Concept Storean exclusive cafeteria for dogs and that includes in its letter “dogguccinos”, “dogtails”, meat lollipops, donuts (“Woof-Waffle”) or empanadillas and special cakes. The canine capuchino is made, for example, with cream without lactose and puppy milk and TOPPINGS They are used are pork, chicken or fish. In the establishment there are also pet accessories. What shows us? Beyond the concrete articles or businesses, the previous examples tell us about two clear trends: the changes of a society in which it is increasingly common to meet pets than with children and the business that is promoting. In February The country did A poll Between veterinarians and it came out that at the end of 2024 in Spain there were 1.6 million cats and 9.3 million dogs. A sum that far exceeds eight million minors. The first two are data that must be handled with some caution, but still give an idea of ​​the growing weight that pets have in the country’s homes. And it’s not something that happens Only in Spain. With that backdrop in recent years they have launched Nursery, Spas, hairdressers, Hotels And even Cruises For dogs. That impulse explains that in 2017 the pet care sector invoices in the EU 36.5 billion of euros, with clear forecasts Growth.

The OCU has analyzed about thirty Tarrina ice cream, the results are not excellent

by

Summer is already here more than one awaits an ice cream binge. Ice cream are rich in sugars and fats, generally ultraprocessed foods and therefore Not especially healthy. Despite this (or perhaps precisely because of it), choosing the healthiest option can be a good idea. New report. Now the Organization of Consumers and Users (OCU) has published the results of its analysis of the Tarrina ice cream that we can find in supermarkets. Your verdict is not optimistic: too many additives, “some not recommended”; and scarce in dairy fats. 32 ice cream. In its analysis, the OCU studied 32 Tarrina ice cream like the ones we can find conventionally in supermarkets. They chose “Family Format” of three flavors (vanilla, chocolate and caramel). The analysis focused on white brand ice cream although it also included specimens of two “first brands”. According to Explain the organizationthe analysis consisted of an assessment made from labeling, nutritional quality (including energy content, fats and sugars used and composition), degree of processing, and a tasting test. The latter represented 50% of the final grade assigned to each product. Bad notes. According to the organization, only 10 of the 32 selected products exceeded the tests, with four of them “highlighting for their quality.” The 28 that did not reach this category, continues to explain the OCU, exceeded the levels in aromas, concentrated, dyes or syrups, which “mask the lack of product quality.” According to the OCU, the low quality in the ingredients was reflected in the taste of the products in the tastings to the palate. “It is not for less, because these are ultra prosecuted products, poor in dairy fat and rich in aromas, syrups and additives, some not recommended,” The organization explains in its statement. Too many additives, few dairy products. As for additives, the OCU identified a total of 20 (an average of 4 per product). Of this twenty additives, the organization highlighted four qualified by OCU itself as “not recommended.” It’s about E442, E471, E472C and E14XX. Only one of the analyzed products was described as “additive free.” The OCU also paid attention to the fats present in the products. He noted that only eight of the ice cream analyzed used dairy or cocoa exclusively. Better chocolate, caramel worse. In the results published by the OCU, a pattern can be perceived, and that is that among the ice cream analyzed, those of chocolate presented Better scoreswhile the caramel scored lower. “Caramel ice cream are the worst valued (in addition to the most caloric)”, details the organization. A product not so healthy. There is no healthy ice cream and that is why it is recommended that this food so desired in summer is only consumed in moderation. Ice cream are foods rich in sugars and fat regardless of the type of sweeteners and fats used. Choosing one or another option can depend on our tastes and what we want to prioritize in our diet.

If the question is whether to freeze a yogurt is a healthy alternative to ice cream, science is clear about the answer

by

The kit to survive summer goes through having something cool: from icy drinks, watermelon in the fridge and, of course, ice cream. But in times of social networks and healthy lifestyle, the classic tubs or cucuruchos have been replaced by options that seem, more “healthy.” Yes, I’m talking about frozen yogurt or, in a more viral version, he Yogurt Bark. What is it? This recipe has gained popularity for being visually attractive and simple to prepare. The idea is simple, Greek yogurt is mixed with fruit or nuts and then extends on a tray, taking it to the freezer. The next day is split into pieces and enjoyed as if it were a sweet tablet, but like many viral trends, you have to go beyond the wrapping. A “healthy” option? Although natural yogurt, especially Greek, provides important nutrients such as proteins, calcium and in some probiotic cases, freezing it can alter some of its functions. According to Mayo Clinicmany probiotic strains do not survive the freezing and defrosting process, especially if proper temperature management and product formulation are not performed. In addition, it is essential to consider the composition of the yogurt used. Many yogurts available in the market are not “natural” in the strict sense: they can contain high levels of added sugars, artificial sweeteners, flavoring and thickening. And if we add sugary topings, the result can be a more caloric preparation than a moderate ration of traditional ice cream. So? Here comes the key summer question: if neither the traditional ice cream nor the frozen yogurt are ideal … so what? The answer is in balance. Eating ice cream every day is not necessarily bad, provided that the rest of your diet is healthy and have no conditions that advise you. The problem is not the ice cream alone, but how it integrates into your habits: do you take it for dessert after a balanced meal? Or do you use it to replace fruits, water or nutritious foods? In that sense, both ice cream and Yoghurt Bark They can have a place, provided they do not replace essential foods or take by system as “healthy without further ado.” THE FIT phenomenon. Taking care of food does not go on to change an ice cream ball for a frozen yogurt sheet and think that it is already. This quick replacement logic – bad, well frozen yogurt – is part of a superficial approach that has been installed thanks to Aesthetics Fit In social networks. However, all this does not go on trends or Hacks. It will understand what one eats, of exercise, rest … health is not measured in calories or Likesbut in balance.

Is it healthy to eat an ice cream each and every day of summer? Science already has an answer

by

In a balanced and varied diet it is not difficult to find a hole for occasional whim, a sweet dessert or a Snack from time to time. Now, finding balance is not always easy, even more so when we often receive news that they point out that foods like ice cream They are healthy, something that seems to contradict our most basic ideas about nutrition. So is this true? How often can I eat ice cream? First, bad news: no, eating ice cream is not especially healthy. As with the consumption of certain alcoholic beverages such as wine, the fact that some study finds positive properties in any of its converters, does not necessarily imply that a food will be healthy. Here it is important to address several issues issues. The first is that there may be other components that cancel the positive effect detected. In the example of wine, its alcohol content tends to counteract the impact of compounds such as polyphenols. A key question to ask ourselves here is if we can obtain the beneficial compounds of a source that does not contain the harmful compounds. It is also relevant to attend to what aspect of health a certain study refers. Analysis can be carried out focused on A specific aspect of healthsuch as the incidence of cardiovascular diseases, diabetes or cancer. It is therefore important to understand that what can be good for one aspect of our health may not be so much for another. Interpreting the results of a study is important, but sometimes the methodology can also give us important clues when making this interpretation. An example we have In an article for The conversation Written by Duane Melor, expert in Medicine and Nutrition of Birmingham Aston University. Although it is an interesting result, some factors must be taken into account, the first, the fact that ice cream represents a small element of the diet and that sometimes other variables can play a bad pass. Melor In a doctoral thesis published in 2018 and focused on the heart effects of dairy products. The thesis, the expert indicates, included a study in which it was observed that, among the study population (composed of people with type 2 diabetes), those who consumed ice cream no more than twice a week showed a 12% lower risk of suffering from cardiovascular diseases, compared to those who did not consume this sweet. Although it is an interesting result, some factors must be taken into account, the first, the fact that ice cream represents a small element of the diet and that sometimes other variables can play a bad pass. “It is important to note that this bond between ice cream and heart disease only becomes apparent when other aspects of people’s health are taken into account, including how healthily they ate,” MELLOR EXPLAIN IN YOUR ARTICLE. “This suggests that eating A generally healthy diet It is possibly more important when reducing the risk of cardiovascular disease in people with type 2 diabetes, compared to eating ice cream. ” Establishing causal relationships in observational studies such as this is difficult and mellor gives us an example of why. A person with problems prior to the study may decide to stop consuming ice cream to improve their diet. This implies that this person will be seen for the purpose of the study as a person with a worse level of health despite leading a seemingly healthier life. If there is a marked trend, that is, if there are numerous cases like this, the results of the study may present biases. Practice and theory Ice cream are usually high caloric food in sugar and in fat. This, as we point out at the beginning, can fit perfectly into a balanced diet, but it does not mean that a food is healthy. He sugar consumption It has been linked to very different problems that cover from oral health to an increased risk of cancer, also through diabetes. Fats and excess calories can also facilitate the appearance of overweight or obesity. While this is not a health problem in itself, it is a risk factor in the appearance of diseases and disorders, including cardiovascular diseases. There are also studies that point in this direction, some of them cited by Melor in their piece. A study Made by an Italian researchers team and published in 2019 in the magazine Nutrientsdetected that greater ice cream consumption was linked to the appearance Non -alcoholic fatty liver diseasesomething that is not exclusive to this food, but we must also take into account when making our nutritional decisions. We explained before something that we must take into account is whether we can find healthier alternatives. Part of The benefits that can give us ice cream come from milk, thanks to elements Like calcium either The probiotics. That is, non -sugary yogurt (or less sugary), cheese, or milk can give us some of these nutrients, turning them into alternatives that may perhaps fit more into a daily diet. So how much can I eat ice cream? There is no clear response, it depends on factors such as the type of ice cream we are consuming (the nutrients that each type of ice cream provides can vary) and the size of the ration, our diet and countless factors such as our weight or our state of health. If we wanted Consume ice cream every day We should make sure first to have A varied diet (and healthy lifestyle habits), consume reduced amounts and eliminate other added sources. And still nothing guarantees that this cannot lead to other problems such as the aforementioned fatty liver disease.

The ice age had a solar storm so powerful that its effects can still be detected in trees

How powerful can it become a solar storm? More than one will have ever asked this question for mere curiosity. And also out of necessity. Answering this question is important in order to prepare in the face of potential storms of great magnitude, but it is complicated: we have a limited sample and the most intensity events are those that happen less frequently. But now we have a new track. The mother of all storms. A recent study has analyzed The remnants of the greatest solar storm of which we have record to date. The storm, about 500 times more powerful than the largest solar storm since the beginning of the space era, would have happened about 14,300 years ago. Although We already had enough previous clues about this eventThe new study facilitates the work of preparing for such events, and can also help us improve our radiocarbon dating techniques. 14,300 years ago. The discovery of this solar storm has been possible thanks to the detection of a radiocarbon peak, the well-known carbon-14, happened towards the year 12,350 AEC, towards the end of the last glacial period. This implies that the storm is not only the most powerful of which we have record, it is also the only solar storm known outside the Holocene, the contemporary geological era (if we exclude the existence debated from the anthropocene). Different storms. The storm analyzed was a solar particle storm. There are different events That we can catalog as solar storms, each with its characteristics, such as radio blackouts, solar radiation storms or geomagnetic storms. Radiation storms, such as the one studied, are produced when large amounts of charged particles from the sun reach the magnetic field of the earth. This field tends to divert the particles towards the poles, making the effect on high latitudes greater. Carbon 14. The team responsible for the new study He turned to a new model Chemist-Climatic, Socol: 14C-EX, for analysis. This is a model designed to rebuild solar storms of particles in climatic conditions of the past glaciations. Thanks to this model, they explain, it was possible to verify that this solar storm was 18% stronger than the event of the year 775 EC, the largest solar storm known until the discovery of this event. “Compared to the largest event in the Modern Era of Satellites (the 2005 particle storm) the old 12,350 AC event was about 500 times more intense, according to our estimates,” explained in a press release Kseniia Golubenko, co -author of the study The details of the study were published In an article In the magazine Earth and Planetary Science Letters. More than establishing a record. The study allows us to establish a new framework to the “most pessimistic scenario,” says Golubenko. Knowing what we can face gives us essential tools when preventing this type of event. The study can also help scientists who study something very different: archaeologists. The analysis has been based on carbon-14, a very important isotope when it comes to very diverse organic matter remains, from fabrics to ships. Understanding the peaks of this isotope caused by the impact of loaded particles from the Sun can help us to date back objects created in past times.
