remember

Every time you think about everything the Romans managed to do, remember that they did it while poisoned by lead.

by

Who isn’t going to like the Roman Empire? A little over a year ago, thousands of women from all over Spain asked their boyfriends, friends or husbands what how much they thought about the Roman Empire. And, at least according to the meme, the answer was: a lot. Poisoned. We discovered it hidden in the Arctic ice because, in short, we thought too little: the Roman Empire built one of the civilizational works most impressive in the history of humanity and it did so with absolutely insane levels of atmospheric lead. Lead that they themselves had thrown into the atmosphere. Lead, lead everywhere. Examining lead in three 2,000-year-old Arctic ice cores, a team of researchers from the Desert Research Institute have been able to calculate the level of environmental pollution in Europe between 500 BC and 600 AD. The data is, to put it mildly and measuredly, terrifying. As published in Proceedings of the National Academy of Scienceafter examining the isotopes of lead stored in that ice, researchers were able to create a map of contamination by this metal throughout Europe. Not only that: they estimated its magnitude, the levels of lead in the blood of the inhabitants, and even discovered what had caused this enormous contamination. A culprit with a name and surname. According to the data, silver is at the origin of all this problem. Or, rather, silver mining. In general and for centuries, miners smelted tons of galena to extract the silver. It is estimated that for every ounce of usable silver, thousands of ounces of lead were released into the environment. Figures. To put it into numbers: “During the 200-year heyday of the Roman Empire, more than 500 kilotons of lead were released into the atmosphere.” This, according to ice core records, is 40 times greater than during the great environmental lead peak of the 1970s (after which we began to remove it from gasoline, paints and other products). And that, of course, had consequences. We already know that lead is bad for our health. Very bad. And not only because of problems of infertility, illness or violence: I am talking about neurological problems that translate into a considerable decrease in cognitive abilities and concentration. Although not all experts agreeIn practical terms, according to DRI researcherslead levels in Roman times had to decrease between 2 and 3 IQ points in the general population. “It doesn’t sound like much, but when applied to practically the entire European population, it is a big problem,” explained Nathan Chellmanco-author of the study. A problem that, seen in perspective, only increases the myth of the Roman Empire.

After the floods in China, the vice president of BYD has had to remember that their cars are not boats. Its owners have not cared

by

Dozens of BYD electric cars have circulated these days on completely flooded roads in the Chinese region of Guangxi, transporting food, water and emergency supplies to villages isolated by the rains. The striking thing is that it was not a decision organized by the brand, but those who left with their cars for the affected areas were volunteers, and they did so just when a senior executive of the company asked for caution regarding the risk of driving through floods. What has happened? Guangxi has suffered historic rains caused by Typhoon Mesaak, with roads and entire municipalities under water. According to collect According to Chinese media, 163, owners of vehicles from brands such as Denza and Fang Cheng Bao, both from the BYD group, organized themselves through networks of owners to form civil rescue convoys. These groups voluntarily entered the areas most affected by the flood, ignoring the recommendations for driving in extreme weather conditions. In detail. Chinese electric cars they usually boast of a construction designed to resist water, including batteries with a highly protective seal and reinforced chassis to cross flooded areas. In the case of Fang Cheng Bao, its independent chassis architecture allows, according to factory data, to cross up to 800 millimeters deep thanks to a specific structural sealing on the underside of the vehicle. And it is not the first time that we see this type of vehicle going out for a ride in extreme conditions. Last year we already saw vehicles like the Yangwang U8 and the Jetour Zongheng G700 do the goat crossing rivers or in flooded areas. There is certainly no better advertising. The notice that arrived late. While the owners were already circulating through the flooded areas, He Zhiqi, senior vice president of BYD, published a message on social networks reminding that an electric car “is not a boat”, according to his Weibo account. The manager explained that, although the Blade Battery of the brand has watertightness certifications IP67 and IP68and that from the factory it is guaranteed that the vehicle can withstand being submerged up to one meter deep for 24 hours without suffering electrical leaks or risk of fire in the battery, driving through deep water is still a real risk that should be avoided. Models on the ground. Among the vehicles that have been seen in the images, the Denza N9 stands out, the brand’s large luxury plug-in hybrid that, according to account CarNewsChina managed to move through areas of mud and water thanks to its all-wheel drive system with several independent motors. The Fang Cheng Bao Bao 8 has also been seen circulating, an all-terrain vehicle with a harder profile with a suspension designed to better distribute the load, in addition to the Denza B5 and B8, which incorporate active body control systems capable of adjusting the height on the fly to avoid obstacles. The money has also moved. In addition to help on the ground, several Chinese brands They have allocated funds to the reconstruction of the area. The BYD Charitable Foundation has donated 10 million yuan (about 1.47 million U.S. dollars) to fund emergency equipment and repair public infrastructure. Xiaomi has contributed the same amount in cash, and the Chery group has donated another 10 million yuan divided between financial aid and supplies.

Soon you won’t need to remember anyone’s name. Meta’s glasses will do it for you

by

We recently learned that Ray-Ban Meta continue recording when you take them off and that there are contractors in Kenya watching everything that happens. They are also being used for things as shady as record women without their consent. In an already delicate context with the issue of privacy, Meta has decided that it was a good idea to add an even more controversial function: facial recognition. The discovery. Wired has analyzed the Meta AI code, which is the companion-app that comes with the glasses, and they have discovered the code for a facial recognition system that has not yet been officially released. The company had previously said that they were “thinking” about how to implement this technology, but the discovery shows that the code began to be deployed last January. Meta has been quietly including all the pieces necessary to get it up and running, so they could launch it at any time. How it works. The function is called internally ‘NameTag’, although its commercial name is believed to be ‘Connections’. It combines three AI models: one detects the face through the camera, another scans it, and the third converts it into biometric data. They are then compared to a database on the user’s phone and, if it detects a person, it sends a notification. That is, if someone who is in that database approaches you, they will tell you who they are. Qwhat does this mean. The ideal scenario from a privacy point of view would be that you can only use it with those contacts who have agreed, but the code says they can take it further. The interesting thing is what happens to faces that are not recognized. The app does not discard them, but rather stores them in a folder called “pending.” And there is something even more striking: the database you have on your mobile is designed to be able to receive Meta updates, that is, they could modify it remotely. There is a possibility that it was used for an “assistive mode”, for example for blind users, in which Meta could include packets of faces of people who have agreed to be included. However, it also opens the door to the creation of a database of faces, with the risks that entails. Criticisms and risks. Cooper Quintin, a security researcher consulted by Wired, criticizes that Meta has “created the ability to turn its clients into a distributed surveillance machine.” Additionally, last April, more than 70 organizations and advocacy groups They demanded that Meta abandon the projectarguing that a system like this, integrated into such a discreet wearable, could normalize the silent identification of strangers and poses a risk to especially vulnerable groups such as immigrants or LGBTQ+ people. Meta has a past. It is not the first time that Meta has had problems with facial recognition functions. In 2010 they integrated photo tagging into Facebook, collecting data from more than 1 billion users. In 2019 the company had to pay a fine of more than 5 billion dollars for privacy violation and in 2021 they closed the system and deleted all facial data. However, Joseph Jerome, a former Meta Reality Labs employee, tells Wired that internally it wasn’t considered a final decision and that “There was always this tension of, well, when do we roll out facial recognition again?” Meta’s response. A spokesperson for the company has insisted that no facial recognition feature has been launched in its glasses and that it being in the code simply indicates that they are “exploring it”. Furthermore, he adds that if they finally launch it, they will do so “with complete transparency” and insists that “we are not building a central facial database.” We will have to wait for the launch.

There is a weapon of mass destruction against our ability to remember things: stress

by

One Monday you see your coworker, Laura, leave the office with a striking bright yellow umbrella. The next day, you walk into a coffee shop and see that same unmistakable umbrella resting on a chair. Without thinking twice, your brain does a quick calculation and you deduce that Laura is in there having coffee. This mental agility, which neuroscientists call “memory integration,” is the invisible tool that allows us to weave together loose ends and construct deductions from experiences separated in time. However, when pressure kicks in, this internal compass goes out of calibration. People who suffer an episode of acute stress not only experience emotional distress; your brain loses the ability to connect past memories with new information. Put bluntly: stress not only erases data from your mind, it also shuts down your ability to deduce. To demonstrate this cognitive “short circuit”, a team of specialists from the University of Hamburg, led by cognitive psychologist Lars Schwabe, designed a thorough experiment combining psychological testing and functional MRI to observe the real-time brain activity of 121 adults. The trial was developed in consecutive and carefully structured stages to compare how a relaxed brain reacts to one under extreme pressure. On the first day, participants memorized pairs of images, such as, for example, an animal next to a landscape. The next day, half of the group was subjected to a high-stress situation through a simulated job interview and complex calculations, while the rest performed relaxed tasks. Right after, everyone had to assimilate new information: they had to connect the same animals from the previous day with 3D figures. The final challenge was pure mental agility, as they were asked to deduce the indirect connection between the landscapes of the first day and the 3D figures of the second. The verdict was clear: the stressed group saw their ability to make these deductions drastically reduced compared to the participants who remained relaxed. Why does stress sabotage the ability to deduce? The epicenter of this problem lies in the hippocampus, a brain region essential for integrating information but which, at the same time, contains a very high density of receptors that are extremely vulnerable to stress hormones. According to the research of Science Advancesbrain imaging revealed that acute stress directly interferes with the reactivation of previous memories. In other words, while the stressed participants tried to learn the new information, their brains retrieved the memories stored the previous day much less intensely. Representational similarity analysis shed even more light on the process: instead of integrating memories into a connected network, the stressed brain encourages the separation of memory patterns. Under stress, our mind prioritizes representing each episode as an isolated and distinctive event, sacrificing the formation of connected and flexible knowledge structures. The research has captured the attention of leading scientific communicators due to its serious implications. In statements to the magazine NatureUniversity of Oregon neuroscientist Brice Kuhl (who was not involved in the research), emphasizes the immense value of being able to visually see what’s wrong in the brain thanks to technology. Kuhl points out that, usually, when something new is assimilated, a “small flash” of past experience rises to the mind, and it is precisely that flash that facilitates the integration of information. In people under pressure, the expert points out, that flash is practically absent. For his part, Kai Schüren, first author of the study explained in Wiredwho insists that the effects of acute stress transcend the emotional: they mechanically alter a vital cognitive mechanism, which prevents the construction of knowledge in an agile way. The current epidemic of mental exhaustion The consequences of this cognitive block are not limited to a laboratory environment, but have a profound impact on various critical areas of our society: In legal contexts, a failure to integrate overlapping events can lead to false inferences by witnesses and, consequently, erroneous accusations. In education, this difficulty in weaving together information hinders the creation of solid memory structures, an essential pillar for academic performance. In clinical health, problems integrating related memories are a distinctive feature of severe disorders such as psychosis and anxiety. To this we must add the current climate of tension in which we live immersed, which turns this finding into a major public health problem. According to the Ipsos Mind Health Reportsociety lives in a state of almost constant alert and pressure. The data in the document reflects the daily wear and tear of the population: 77% of people report suffering from multiple factors that negatively impact their mental health. Uncertainty about the future in a changing world affects and worries 57% of those surveyed. Financial instability and job insecurity are positioned as a source of constant stress for 56% of the sample. Continuous exposure to negative news in the media harms 49%. This chronic pressure means that an alarming 56% of people rate their level of stress experienced in the last twelve months with a score higher than 5 out of 10, while 31% admit to currently suffering from a mental health condition. We often consider stress as simply an emotional backpack that exhausts the body and clouds the mood. However, scientific evidence shows us that its impact is much deeper: stress redesigns the way we archive and use our own lives. By blocking neural connections in our hippocampus, the pressure not only makes us forgetful, it robs us of our innate ability to connect the dots. The next step for scientists, who are already preparing tests with rodents, will be to unravel the exact mechanisms to find ways to reverse this effect on memory. Meanwhile, understanding that stress isolates us in a fragmented present is the first strategic move to protect our mind.

If you are going to install air conditioning, remember what happened to South Korea. It was the architectural disaster of the millennium

by

In the 1990s, some of Asia’s densest cities reached concentrate millions of people in urban areas built in just a few decades. In that same period, several studies began to warn that a significant part of the buildings erected during the great economic booms had serious structural deficiencies. In fact, in some inspections after major accidents, it was estimated that only a minority of buildings fully complied security standards. When you grow faster than you can build. In a few decades, South Korea went from the devastation of war to becoming an industrial and urban powerwith a speed of growth that was hardly unprecedented. Furthermore, during the economic boom in the 1980s, the country was chosen to host the 1988 Olympic Games, and an exorbitant number of buildings were built to meet these new needs. That impulse translated into a construction fever where building architectures mattered more than doing them well, and where practices such as cutting costs, accelerating deadlines or ignoring technical warnings became common. In that scenario was born Sampoong Department Storenot as a project exceptionally flawed from the beginning, but as a typical product of an era when progress was measured in square meters and not in safety standards. Air conditioning as a wick. The key point of the tragedy that was about to take place and that ended up turning the department store into the millennium architectural disasterit was not a single error, but a chain of decisions that ended up concentrating all the fragility of the building in an apparently secondary detail: the air conditioning system. As? Apparently, the equipment installed on the roof They weighed tens of tonsfar above what the structure could support, and their accelerated installation did not even follow normal procedures, as they were dragged on the roof, damaging the structure itself. From that moment on, a terrifying image: every vibration when you turn them on widened invisible cracks that toured the building. What should have been an element of comfort became a lethal burden that ended up acting as the final trigger for the collapse, concentrating years of accumulated negligence in a single point. The department store before the disaster Condemned from the plans. The disaster began long before anyone heard creaking in the ceiling. The original project It was a residential block four floors, but was transformed by Lee Joon, future director of the Sampoong Group, to turn it into a large shopping center without properly redesigning the structure. Plus: Due to bans in Seoul that prevented foreign companies from signing contracts in the city, these monstrous buildings were awarded to a handful of South Korean companies. Overwhelmed by pressure, companies decided that it was best to accelerate the pace of work, regardless of the cost. Thus, the diameter of the pillars was reduced from 80 to 60 centimetersand the distance between them was increased to increase the useful surface, columns removed to install escalators, its thickness was reduced to gain commercial space and a fifth floor was added that was never planned. Each modification increased the weight and weakened the resistancewhile companies that warned of the danger were fired and replaced by more accommodating ones. The result was a chaotic building that, on paper, no longer had a safety margin even before opening its doors. Cracks getting bigger. In the months before the collapse, the building gave multiple warnings that something was wrong. Visible cracks appeared, floors vibrated, employees felt dizzy, and engineers warned of a imminent structural failure. The management’s reaction was to close some areas, turn off the air conditioning at the last minute and continue operating normally in the rest of the building. The reason was so simple as devastating: Losing a day of sales in a complex that received thousands of people was unacceptable. Even on the day of the collapse, with cracks of several centimeters and obvious signs of danger, it was decided do not evacuate customers. Images after the collapse The collapse. On the afternoon of June 29, 1995, the building did not explode nor was it the victim of an external attack: he just gave in to the crazy number of negligence. The air conditioning equipment ended up passing through the weakened roof, the columns could not support the accumulated load and the building collapsed. collapsed in a matter of 20 secondscrushing entire plants on top of each other. More than 500 people died and more than a thousand were trapped, many of them in a space that, just a few hours before, symbolized the country’s economic success. It was a destruction so rapid that it turned a shopping center full of life into a mountain of rubble in less than half a minute. Images after the collapse An avoidable tragedy. Rescue efforts continued for weeks, with survivors found even more than two weeks later under the remains of the building. But the magnitude of the disaster revealed an even more disturbing reality: many victims did not die only from the collapse, but due to subsequent failures in emergency management. Meanwhile, investigations confirmed the most obvious: there was not a single cause, but one after another.accumulation of avoidable errorsfrom the use of low-quality materials to business decisions that prioritized immediate profit over any safety criteria. Monument in memory of the collapse Corruption, punishment and a system in question. The collapse not only destroyed a building, but exposed an entire system. Those responsible, starting with owner Lee Joon, were convicted, including several officials involved in corrupt practices, but the impact was much broader. Subsequent inspections revealed that a significant portion of Seoul’s buildings had very serious structural problemswhich forced us to review regulations and reinforce controls. The Sampoong ceased to be an isolated case and became in a symbol of what happens when a society builds too quickly and too badly. The legacy. Today, where the building stood there is no visible trace of the tragedy, but its lesson remains crystal clear. The disaster was not the result of bad luck … Read more

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

by

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

by

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

by

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

by

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

by

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.
