to think that the beach of your childhood was going to be how you remember it

For decades, coastal architecture was built on such a simple idea as wrongas if the beach of our childhood, the same one we retain in our memories, were going to remain intact forever. Matalascanas is the most recent reminder of a failure of origin: beaches are not everlasting decorations, they are borders that sooner or later are eaten by the ocean. A poorly thought out coast. In Matalascanasthe sea no longer advances in the abstract or in technical reports: it is literally entering the courtyardsdemolishes beach bars and turns boardwalks into twisted rubble. What for decades was a wide, stable beach has lost its protective sand, leaving homes and infrastructure exposed to increasingly stormy weather. more frequent and intense. Built in the sixties and seventies in a high natural erosion zonewithout studies of coastal dynamics and dune systems that acted as a barrier, urbanization embodies the clash between an architecture designed for a fixed sea and a coast that was always in motion. The storms of 2026 have done nothing more than accelerate an announced process for years, generating a feeling of abandonment and urgency in neighbors who see how emergency solutions arrive late and are never definitive. Exception turned into routine. What happened after Storm Francis was not an isolated episode, but rather the start of a sequence. Just weeks later, a new storm has once again placed water at the doors of houses, sweeping away beach bars and reopening unclosed wounds. Erosion is no longer a future threat but has become in a permanent stateaggravated by the lack of coordination between administrations and by provisional actions that barely buy time. In Matalascañas it is no longer discussed whether the sea will advance, but rather how much and at what pacewhile the natural balance that allowed the beach to recover after storms has been broken for two decades. Matalascañas Plug Science takes on the unthinkable. What neighbors experience as a local tragedy, science has been formulating for some time as a global dilemma. Studies in the UK in 2022 now they had warned that hundreds of thousands of coastal homes could be exposed or directly abandoned in a few decades, because protecting them will be economically and technically unfeasible. The message is uncomfortable, but quite clear: there will be communities that must retreat inland. The sea not only rises, it also erodes the beaches and raises the point from which the waves break, multiplying the impact of each storm and rendering many traditional defenses useless. Map of the Earth with a sea level rise of six meters depicted in red Beaches and economies at risk. On a planetary scale, the erosion of sandy beaches is advancing rapidly. uneven but persistent. A significant part of the world’s sandbanks is already receding and projections point to severe losses before mid-century. Tourism, frontline urbanization, ports, dams and dune destruction have eliminated natural reservoirs of sand that allowed the beaches to adapt. In regions highly dependent on coastal tourism, such as the Spanish Mediterranean, the disappearance of the beach is not only an environmental problem, but a direct threat to the economic and social fabric built around it. Barceloneta And the north, the same. Of course, it is not just a problem for Spain. In Scotland, for example, Montrose beach loses meters of sand every year at a rate that even exceeds scientific forecasts. Collapsed promenades, weakened dunes and historic golf courses devoured by the sea show that the problem does not distinguish latitudes. The proposed solutions, such as artificial regeneration with sand, are expensive and recurringa structural expense that is difficult to assume for indebted administrations. The question, again, stops being how to stop erosion and becomes how long can it be buy before the defenses give way. Shrinking cities. In large urban areas such as the same New Yorkthe rising sea threatens tens of thousands of homes in a context of serious housing shortage. I remembered a few months ago the new york times that there the withdrawal is no longer just coastal, but urban: buying houses, demolishing them and returning the land to the water becomes an adaptation strategywhile large protection projects advance slowly and force us to rethink the classic housing model. The coast stops being a place to grow and becomes a mobile border that determines the future of the city. Save house or beach. In the United States, the advance of the sea is of such magnitude that it has reactivated a legal conflict inherited from centuries: the beaches as a public good against the right to protect private property. The walls and breakwaters that save a house condemn the beach by disappearing, causing the call “coastal choke”. The consequence is a waterfall of judicial conflictswhere each individual defense accelerates the erosion of the environment and forces neighbors to follow the same path, until there is no sand left to defend. A “national” problem that aims to be global. Adapt without going out of your way. Of course, all kinds of solutions are being tried. I remembered a few months ago the Guardian the case of the Pacific coast of Colombia, where communities like Juanchaco face erosion from a different logic. Without major works or resources for a total withdrawal, they opt to internal displacementscommunity tourism and progressive adaptation. The sea carries away streets and houses, but the community responds by moving a few meters inland, reinventing its economy and preserving its cultural identity. It is a form of resistance that assumes physical loss without giving up territory. A solution that seems impossible in depending on which enclaves. Houses fall, value sinks. A few months ago it went viral a series of snapshots. Images of homes collapsing on the beaches of North Carolina seemed absurd until you understand their logic. Many were built at a safe distance from the sea, when architecture never imagined that the beaches would change, building on dunes that no longer exist. Accelerated erosion has turned those investments in trapped assetsdifficult to … Read more

How not to remember things makes us think better

Irenaeus Funes was 19 when, after an accident, he lost knowledge and, when recovering it, he debuted with a very rare case of hypermnesia: Your memory It had widen in a prodigious, superlative, elephantiatic way. Now, in their drawers, the whole world and each of its details fit. “More memories I have that those who have had all men since the world is world,” he told a Buenos Aires pack that his story kept us in A small text destined for a collective biography that never got edited. But, very soon, both began to discover that “the gift” was poisoned. Funes began to talk about his memory as a “garbage emptying” and the writer realizes that the Uruguayan young man was so full of insignificance that he had become someone unable to think. “Thinking is forgetting differences, it is to generalize, abstract. In the crowded world of Funes there were only details, almost immediate,” wrote in 1944. That is, Borges readers already knew that oblivion is more than necessary. Now also confirms neuroscience. How are long -term memories saved? I am not sure that ‘saving’ is the term more prices, but it will be worthwhile to talk about the subject today. In its most basic aspect, “long -term memories are stored as configurations of neuronal sets, called greases.” The term “engram” is actually used for many things (with unequal rigor) because it refers to any relatively stable interconnection of neurons. Just the type of patterns we are when studying long -term memory. A lot has been studied on the properties of these structures and the functionalities that the engrams have, but (how did they realize Some researchers from Dublin Trinity College) still know very little “about how they are affected by oblivion.” Not only the distance is oblivion. In fact, the Irish team study How affected the ‘retroactive interference‘(A phenomenon in which different experiences that occur nearby in time can cause the oblivion of recently trained memories) to the engrams. In an experiment with mice, The researchers created A memory, identified the ‘linked’ engram to him, made him disappear with retroactive intervention techniques and, subsequently, thanks to optogenetics, analyzed what happened to that hook. What they discovered is that “forgotten” greases can be restored by presenting similar or related environmental information. That is, they have shown that “retroactive interference modulates the expression of the engrams in a reversible and update way.” In a way, if we think of greases like ‘roads’ that connect certain neuronsafter oblivion those paths stop being used, but (as in the real roads) the brands remain in the “vegetation” and can be followed with some ease if necessary. Forgetting, thus, simplifies communications networks in the brain, without destroying them at all. Something that is “adaptive” for a daily life in which “new perceptual and environmental entries” modulate oblivion). It is not a problem, no; It is a characteristic that makes us better.

Grok will also remember all our conversations with him. The new generative AI tendency is already here

XAI, Elon Musk’s company, has announced The incorporation of a memory function for its Chatbot Grok, which can now remember details of past conversations to offer more personalized answers. Why is it important. Memory integration is a huge step in the evolution of the AI ​​attendees, transforming them to tools for specific tasks to digital partners who learn and adapt over time. This update reduces Grok’s gap with its rivals. Chatgpt It has been offering a similar but newly improved function for some time to be able to refer to the entire user conversations history. Gemini also has persistent memory to customize your answers. In detail. This new function allows the assistant to retain previous interactions information. You will remember whether we told him that we only want to use Python to program or if we ask for advice to improve running from concrete MMPs. The function is available in beta through Grok’s website and its mobile applications, although it is not yet accessible to users in the European Union or the United Kingdom. The context. Grok 3 already stood out for its speed and intelligence, but as we said at the timeIt lacks elements that make it attractive to recurring and professional use, compared to competition options. I had nothing similar to projects, GPTS either Gems. It still does not have it, but at least now it goes further in product development with a persistent memory. Between the lines. The implementation of memory implies a huge change in human relationship. It allows you to move from the unique and state consultation model that characterized the first systems of AI towards more continuous relationships that are built over time, which they remember. The AI ​​attendees go from being specific tools to becoming digital partners who know our preferences, history and needs. How it works. XAI has emphasized transparency In memory management, allowing users: See exactly what information Grok remembers. Disable the function from the configuration. Eliminate individual “memories.” And now what. The question is whether Grok is going to get thanks to this novelty differentiates himself in an increasingly competitive space or if he will be relegated to punctual anecdote in a saturated market. Xai still has to show that Grok can make something differential and real useful on a day -to -day basis, not only in specific uses closest to hobby. This is a great step in that direction.

What are they and how to manage or delete the key data that you remember about you and use in all chats

Let’s explain What is the chatgpt memory and howa system with which artificial intelligence remembers several key data about you. Because now Chatgpt remembers things you talked in the past, and will take them into account to use them in the future. We are going to start the article explaining what exactly is the chatgpt memory, telling you what it is for and putting some examples about your operation. Then we will tell you How to manage stored memories that you have from your chats to be able to erase some or all. What is the chatgpt memory Chatgpt is now capable of Remember useful information about you that is extracting from the conversations you have with him. For example, if in any conversation you tell him what your musical tastes are or where you work, the AI ​​will remember this information to use it in future chats. Each data of interest that Chatgpt keeps on you is a memory, and the chatbot stores memories with which to have these relevant data. The idea is to be able to Offer more personalized and relevant answers taking into account the context of the data about you. For example, something funny that happened to me. At a specific moment I spoke with Chatgpt about a musical group that I liked a lot. I said it passed, I think that to ask for some illustration or drawing with his name. He recalled this, and a few weeks later I asked to reimagine a photo of mine in the Ghibli style, and in the drawing he put me with the shirt of this band. There are two ways in which Chatgpt stores memories. First, it can be from normal conversations when you mention key data. But also You can ask you to remember something telling him to remember something, saying for example “remember that my favorite color is black.” You have control over Chatgpt’s memories, and you will be able to eliminate them individually or reset all erasing them. You can also deactivate this function so that you do not remember things or using what is remembered. And if you have it activated but want to start a chat that does not take into account the memoryyou can do it with the option to start a temporary chat. How to review and eliminate memories To review and manage the memories stored in chatgpt, you have to enter the configuration of this artificial intelligence. You can do it from its official website or from mobile and computer applications. Once within the configuration, Enter the section of Personalization. Here, under custom instructions You have the options for Memory. You can deactivate referring to the stored memoirs in the event that you do not want them to be used in your chats, and below you will have the option of Manage memories. If you click on Manage memorieswill be shown A list with all stored memories In chatgpt. In it, you can read what you are remembering in each one, and you will have to the right the option to erase the ones you want. You also have a button to eliminate everything if you want to forget everything you are remembering.

Every time you think about everything the Romans managed to do, remember that they did it intoxicated with lead

Who will not like the Roman Empire? A little over a year ago, thousands of women from all over Spain asked their boyfriends, friends or husbands to How much they thought of the Roman Empire. And, at least according to the meme, the answer was: a lot. What we just discovered hidden in Arctic ice is that, in short, we think too little: the Roman Empire He raised one of the civilizational works more impressive in the history of humanity and did it with absolutely demential atmospheric levels. Lead that they themselves had launched to the atmosphere. Lead, lead everywhere. Examining lead in three Arctic Ice Cores 2,000 years ago, a team of deserting institute researchers They have been able to calculate The level of environmental pollution in Europe between 500 before Christ and 600 after Christ. The data is, to put it in a gentle and restrained way, terrifying. As They publish in Proceedings of the National Academy of ScienceAfter examining the lead isotopes stored on that ice, researchers could create a map of pollution by this metal throughout Europe. Not only that: they estimated their magnitude, the blood lead levels of the inhabitants and even discovered what had caused that enormous pollution. A guilty with name and surname. According to data, silver is at the origin of this problem. Or, rather, the Mining of La Plata. In general and for centuries, the miners melled tons of galena To extract silver. It is estimated that by each ounce of useful silver thousands of ounces of lead to the environment were released. To put it in numbers: “During the 200 years of apogee of the Roman Empire, more than 500 kilotons of lead to the atmosphere were released.” This, always according to the records of the ice centers, is 40 times greater than during the large environmental lead peak of the 70s (after which we began to withdraw it from gasoline, paintings and the rest of the products). And that, of course, there were consequences. We already know that lead is bad for health. Very bad. And not only because of infertility, illness or violence problems: I talk about neurological problems that translate into a considerable decrease in cognitive abilities and concentration. In practical terms, According to DRI researcherslead levels in Roman times had to decrease between 2 and 3 points of intellectual coefficient in the general population. “It does not seem much, but when it applies to practically the entire European population, it is a big problem,” Nathan Chellman explainedCo -author of the study. A problem that, seen in perspective, only increases the myth of the Roman Empire.

If the Electric Ford Capri seems strange to you, it is because you do not remember that one day it took a motorcycle engine. Yes, a V4 engine

2.- Molancholic sadness originated by the memory of a loss Nostalgia has come to stay in the car market. It makes a lot of sense, if we think coldly. We are facing a historical moment in the automobile industry. The regulatory changes and a new technology that seems to be average price increased of a car to Remove some capabilities He has made many feel expelled from this “new mobility.” Nostalgia applied to the automobile market is nothing more than the redundancy of A constant of our societyencouraged to constantly remind us that all the past was better. And it does not have to be exactly like that but manufacturers have decided to enter the game. If the most common buyer of a new car exceeds 45 years and what lived between 15 and 25 years We consider it as the best time of our life … You just have to subtract. That is why Renault has risen to Renault 5which ceased to be manufactured 40 years ago and was an essential part of the childhood of those buyers who are already well entered in the forties. The same buyers who have the purchasing power to get those cars. He will follow him Renault 4 and the Twingo. It is about attracting the electric car market to an audience that needs stimuli and incentives that appeal to their feelings. Ford opted for a slightly more risky strategy: use mythical names. He did it with the Ford Mustang, who was left an electric brother. And he has done it with the Ford Capri. A car that was an icon of the 70s and a large part of the 80s. Subtracts, again, and checks who is directed An electric car called Ford Capri. Renault has opted for popular models but Ford has chosen the way to resurrect names that have a space of honor in the collective imaginary of car lovers. And, with this, they have gotten the most staunch defenders to be thrown on them but have also managed to get to those who would cost more money with higher investments in marketing. An example of that selective memory and understanding that the past was better for the simple fact that we remember it is the case of Ford Capri. Yes, it has risen as an electric car but in its day it also came to set up an unexpected, weird and that of course we do not associate with the Muscle Cars American. A motorcycle engine in a mythical car That generalized image we have of “American car” of the Ford Capri is not such and partly distorted by memory. The car was born as a European version of Ford Mustang. That forced to make a smaller car, with also smaller engines and, above all, except gastons. That led Ford to opt for a curious solution with the launch at the end of the 60s: mount a V4 engine. Ford’s intention was to make Capri A car that young Europeans could buythat was not expensive and that offered a cheap and sports alternative to the classic German Coupés. The proper functioning of Mustang In the United States they convinced them that they could get a similar result in Europe. With that premise, it was about recycling all possible components to prevent development from being price. With that premise, Ford brought out a V4 engine. A very little used concept in the car market because it forces to develop a propeller with Two ass, two exhaust collectors and two valve trains. That is much more complicated than a four -cylinder engine online. In return, you get a propeller with a very characteristic sound and very contained dimensions. Width it can be a problem if the car is very narrow but it is a much more compact option than its older brothers. In addition, the power delivery was softer than with a four -cylinder online, although it does not reach the refinement of a V6 or a V8. That compact size is perfect for a high performance motorcycle. Its power can go above 100 hp easily and entered in this field, the configuration is ideal for high performance motorcycles. In a car, where the weight is much greater, this advantage is very eclipsed. Ford’s V4 engine we already knew it in Europe. The company put it at the service of Ford Taunus and was Saab’s supplier. Also Lancia with the fulvia He had tried unsuccessfully to make the V4 engine an alternative to the four online cylinders. Despite their best behavior, the high development and production costs finished killing a propeller that we would see again in the Porsche 919 Hybrid of Le Mans. But that is another story.
