We had supplements to live more, improve our strength and sleep better. Now we have one to get less angry

We are likely to associate the name “Omega-3” for the beneficial effects that these fatty acids have on our cardiovascular health. However, over time we have discovered that these compounds They have more advantages. Let’s not lose the papers. For example, Now we know That the consumption of omega-3 fatty acid supplements is related to less aggressiveness. It is the conclusion reached by a group of experts after reviewing almost thirty studies on the subject published between 1996 and 2024. Omega-3. Surely we have heard on numerous occasions about the Omega-3 but what are they really? It is a group of polyunsaturated fatty acids that we often obtain through fish consumption (especially species such as northern bonito or white tuna, mackerel, salmon, sardines and trout), but which we can also find in other foods, such as nuts, flaxseed oil, soybean or chia seeds. We usually associate these fatty acids with better cardiovascular healthand for good reason: they reduce the presence of triglycerides (other types of fat present in our blood, these not so beneficial), as well as decrease the possibility of developing arrhythmias or the accumulation of plaque in our arteries. These fatty acids can also help us reduce blood pressure. Body and mind. But the studies carried out around the physiological benefits of these compounds have been complemented with analysis on the psychological and neurological impacts. Studies like a decade ago He detected a relationship between these nutrients and schizophrenia, or clinical trials that began establishing their relationship with aggression levels. 29 randomized essays. The team responsible for the new analysis compiled 35 independent samples extracted from 29 studies (including 3,918 participants) published between 1996 and 2024. From this exhibition, the team conducted a meta -analysis, a quantitative study of compiled essays. This served to detect modest but statistically significant effects in the relationship between Omega-3 and aggression. The team estimated a reduction of almost 30% in the levels of aggression, apart from gender age, diagnosis, duration of treatment and dose. The analysis found evidence that these fatty acids could reduce both reactive aggression (in response to a provocation), such as provocative (planned) aggression. The details of the study were published In an article In the magazine Aggressive and Violent Behavior. Continue investigating. Those responsible for the new study indicate that the fact that Omega-3 fatty acids are a normal component of our diet that we can find in a simple way in the form of supplement makes them a harmless treatment when reducing aggressiveness. Therefore, although there are important limitations regarding what we know about its effectiveness, they recommend their use, even as a complement to other measures. “The Omega-3 is not a magical bullet that will solve the problem of violence in society. But can it help? Based on these findings, we firmly believe that it can, and that we should start acting based on the new knowledge we have,” pointed in a press release Adrian Raine, co -author of the study. Despite this, the limitations that can be considered. For example, we do not know the biochemical mechanisms that could justify the casual relationship between Omega-3 consumption and the reduction of aggressiveness. In addition, according to Raine himself, analyzed studies focused mainly on short -term effects, so the task of evaluating them in the longer term is still pending.

China built the largest high speed network in record time. Now you want something more difficult: improve it

by

China has already shown that you can do what no other country has achieved: display in record time The largest high speed network on the planet. But it is not enough to have it. The new challenge is even more complex: to improve it, make it more efficient, more connected, more useful for the economy. And that demands less colorful, but equally ambitious decisions. To grow quickly to grow well. Between 2021 and 2024, China added 10,000 Kilometers of track to your high speed network. The figure impresses, but it is no longer what defines success. The Ministry of Transportation has made it clear that the current objective is not to extend the railway map without pause, but to squeeze its potential. In fact, The country has set As a goal to reach 50,000 operating kilometers before the end of 2025. The network adds 48,000 kilometers, more than 70 % of the world total, and connects 97 % of cities with more than 500,000 inhabitants. Millions of travelers, but there is still a margin of improvement. Only in the first half of 2025, Chinese high -speed trains They transported 2,240 million people. The figure impresses, but the authorities are not formed. The objective now is to make this system more comfortable, more predictable and better coordinated with the rest of the transport ecosystem, from the urban metro to airports. High speed yes, but also logistics. China wants its high -speed trains to cease to be just a solution for travelers. The new approach includes routes adapted to the transport of goods, interconnections with airports and sea nodes, and improvements to integrate the system into the production chain. What is at stake is no longer only mobility, but the country’s competitiveness. Beyond traditional rails. While the current network is kept, China develops new generations of trains, such as magnetic levitation. These advances do not seek to replace what is built, but prepare for a future where speed, autonomy and sustainability are key. The country has already tried prototypes that reach 600 km/h In cities like Qingdao. Figures that impress. Security that holds. Moving millions every day with punctuality is an achievement. Doing it without major incidents, for years, it is even more. China has built a network that not only runs quickly, but aims to resist earthquakes, storms and overloads. According to Xinhuasince 2012 no serious accident has been registered in the high speed network. Centralized planning. Faced with chronic delays that affect many countries, China has maintained a clear strategy: centralized decisions, sustained investment and state control of the process. It is not a perfect model – there are errors, cost overruns and debatable decisions. But its results in deployment and integration are difficult to ignore. A mature network, a major challenge. As we have seen, the Asian giant continues to expand its network, especially towards interior and less connected regions. However, it is no longer just about adding cities to the map. The real challenge is another: to ensure that a gigantic infrastructure works better and better, with less margin of error and more logistics demands. The stage of the big deployments is giving way to the stage of precision.

The most experienced developers hoped to improve their productivity with AI. A study showed just the opposite

by

What happens when you give an advanced artificial intelligence platform to a group of expert developers and ask them to work on tasks that they know in detail? The logical thing would be to wait a productivity jump, a great combination between experience human and technological assistance. The tools are there, the flows are learned, the learning curve is not an obstacle. But it was not so. What happened even surprised the authors of the study, according to Reuters: AI did not improve the results. He got them worse. And he did it in such a subtle way that not even the developers themselves realized. The report does not talk about critical failures or serious mistakes, but the effect was clear: the work became slower. Slower than it would have been without artificial intelligence in between. More does not always mean more productivity Before starting, everyone agreed on something: using artificial intelligence was going to save them time. In fact, they estimated that their tasks would finish 24 % faster. It was a reasonable expectation, based on their experience and how these tools were presented. And when they ended, they were still convinced of having achieved it: their estimate was that They had been 20 % faster. In his own words, AI had allowed them to advance without blockages, without interruptions, with a more agile workflow. But not. Actually, they had taken longer. A lot more. The general average of the group was a 19 % increase in total time during the test carried out by Metr. It is not a minor difference. And it is even more striking if one takes into account that we talk about tasks that they themselves had defined as relevant, useful and realistic: bugs correction, new functionalities, refactors. They were not exercises designed to test the AI, but real work, of the one that is done every day in any mature project. The difference was so great that he left even words even to those responsible for the study. The developers were not novice or learning on the fly. They had been working on those same projects for years, They knew the repositories in detailThey knew what was behind each file and each function. They were in their field. And, yet, the tools of AI did not facilitate work. They complicated it. Part of the explanation is how these platforms work. The suggestions they offered were not entirely incorrect, but imprecise. They were often well aimed, but required adjustments. And those adjustments, instead of saving time, elongated it. Check, correct, check. Start over. What promised to be an aid became a more intermediate process: an additional layer between thought and the solution. The feeling of fluidity was misleading. They started with a base, yes, but that base rarely served as is. You had to crumble itunderstand what the model had wanted to say, compare with what already existed and rebuild what is necessary. As if each suggestion came with an invisible asterisk. A non -valid line of default code. The illusion of progress faster was held until the time came to compile, try or make a serious review of the code generated. And yet, many of the participants continue to use those same tools in their day to day. Not because they save them time, but because they do the most bearable job. In the study they mainly used cursor, a platform that integrates advanced language models such as Claude 3.5 and 3.7 Sonnetand that allows writing, completing and reviewing code directly from the development environment. Cursor does not do everything for you, but he accompanies you. That company, even when it is not entirely efficient, can make programming less exhausting. The AI ​​converts the effort to program in something more similar to being an orchestra director that to build everything from scratch with a solid knowledge base. We are already seeing it with the phenomenon Vibe Coding. In the midst of this scenario we have seen companies They cut development equipment for the possibilities offered by AI, although Some have had returned on their steps. AI is a valuable tool, but it doesn’t help everyone equally.

It is not you, it’s hotter than ever. And the problem is that summers are not going to improve over time

by

A good part of the planet is clear about one thing: it’s hota lot. So much that life during the day It makes complicated. Last June it became the New Julywhat leaves us a disturbing question now that we started new month: what will happen in July? Many wonder if what happens is “normal”, and the truth is that scientists have an answer: it is not only suffocating. Anticipated and prolonged. As we said, summer did not wait for July. With anticipated heat waves that have fried To Canada, the northeast of the United States, the United Kingdom, France, the Netherlands, and a good part of northern Europe, the 2025 summer season is being configured as another forceful evidence of the rapid advance of climate change. The pools in Toronto They remain open Until midnight, concerts are being canceled in Amsterdam and fans They have reappeared In French homes earlier than usual. The alarming is not just the heat intensitybut its chronology: the thermal threshold that previously marked the beginning of the warmest period of the northern hemisphere was reached around July 10. In 2024, the hottest year Never registered, it was exceeded from June 13 to September 5. This year, without being as extreme as the previous one, this weeks advanced regarding the historical average. The phenomenon reflects A clear pattern: summers are lengthening at both ends, starting before and ending later, which increases exposure to heat waves and elevates substantially The health risksagricultural and environmental. Heat out of time. I remembered The Washington Post That heat waves are no longer limited seasonal phenomena, but an increasingly continuous threat. According to data From the United States Environmental Protection Agency, its duration, frequency and intensity have increased significantly in the last seven decades, extending the “extreme heat season” of less than 50 days in the 90s to about 70 Since 2020. This phenomenon has altered the climate calendar in a drastic way: between January and mid -June of this year, 163 of 171 days registered temperatures greater than 32.2 ° C in extensive regions of the northern hemisphere, a figure unprecedented since 1980. Examples The consequences are manifested Multiple: anticipated forest fires, Early melting of glaciers in the Swiss Alps or the increase of deaths due to heat stroke, which in Europe have risen 30% In the last 20 years. The danger increases Especially in early heat waves, when the population has not yet adapted physiologically nor has preventive protocols activated, more seriously affecting older or vulnerable people. Heating accelerates. He underlined The New York Times That the evidence shows that the planet is heating, and is doing it faster than the models predicted just a few decades ago. The summer of 2025 had barely begun when the United States was already caught under that suffocating “heat dome” of The one we talk about who beat records, while Alaska registered his First official alert by high temperatures. As we said, these anomalies arrive after 2024 that was the warmer year Never registered, and reinforce what climate science has been anticipating: global warming caused by human activity not only continues its course, but also that It is accelerating. More science. A Recent study estimates that the average global temperature is increasing at the rate of 0.27 ° C per decadea significantly higher rate to the rhythm of 0.2 ° C that was observed in the 70s. But beyond the figures, the most disturbing is how these changes have begun to demonstrate directly And visible in everyday life: devastating floods, extreme droughts, increasingly voracious fires and heat waves that challenge the limits of the human body and modern infrastructure. The ends grow faster. In this way, each additional tenth not only adds heat to the planet, but also increased the violence of Meteorological phenomena extremes. According to the climatologist Daniel Swainevents such as torrential rains or forest fires do not grow in a straight line with the temperature: they do it with An exponential pattern. For each Celsius heating grade, extreme rainfall increases by 7%, but the so -called “record events” are doubling that rate. This intensification was not only predictable, but the scientists had already modeled it, although now it begins to feel tangible and disconcerting. Kate Marvel, another recognized climatologist, summarized it like this In the Times: “There is no climate out of climate change.” Phenomena like him Hurricane Helene or historical floods of Vermont They are not anomalies, but direct expressions of an altered atmosphere. Although a total understanding of the most extreme events is still lacking (in part because its rarity makes it difficult to Adjust your models urgently. Accelerated thaws. The impact of heating feels with special severity in vulnerable regions such as The Arctic and Antarctica. The thaw of his ice masses, which for decades seemed a distant phenomenon, is now contributing to a faster sea level rise than expected. A NASA analysis Posted in March revealed that the level of the oceans increased by 2024 to A higher rhythm to the estimated, due to the thermal expansion of the waters (heated in depth) and to the accelerated thaw of glaciers. The sea and the planet. In addition, the data from another study of the National Center for Earth Observation show that the marine surface temperature It is increasing above the previous forecasts, which has direct implications for The global climateprecipitation patterns and cyclones intensity. Cecilia Bitz, an expert in climatic modeling, acknowledges that simulating the complexity of the Earth is a challenge, but insists that the great physical principles of the climate system They are still valid: They are not being denied, but complying with disturbing accuracy. The energy imbalance. The physical root of global warming is in the Energy imbalance From the planet: the difference between the solar energy that the Earth receives and the one that returns to space. According to Another study Recent based on NASA satellite data, that imbalance It has doubled In the last two decades and is now … Read more

The mobile industry has been desperate for years to improve its cameras. Honor believes having found the key

by

A few weeks ago I had the opportunity to try the Honor 400 Pro. It is a mid-high-end phone with the focus on mobile photography. So far, there is nothing especially surprising. But if I tell you that this phone sets the bases of a Honor who does not believe that the future of photography is in the hardwarebut in cloud computing, things may change. In Xataka we have been able to talk to Luo Wei, Chief Imaging Architect of Honor. He is the one in charge of leading the photography part, applied to it and super zoom in honor, and ex-huawei. And someone who is clear that to win the smartphone career you have to win the AI ​​race. If marketing sounds like you can be calm. It is not, it is the vision of the future of a giant who aspires to conquer Europe. Honor wants to lead in Europe, and wants to do it with ia To understand why AI for honor in phones is so important and not misunderstand it as a marketing exercise, it is necessary to know the relevance that the company has with its Alpha plan. In March 2025, the company revealed a investment of 10,000 million dollars In five years to promote artificial intelligence on their devices and display your first AI agent, in association with Qualcomm and Google. The objective is clear: lead the AI ​​agents in the mobile ecosystem and be the main reference in this race. At the moment, he will do it hand in hand with these two partners in Europe. Honor has different strategies for China and Europe. In our territory, Google Cloud is the main partner It is also relevant to understand that this plan has a lot to do with The position of honor in Europe and how it aspires to conquer our market, more than a proposal centered purely on your native country. With counterpoint data in your hand, Honor is the brand that grows most in shipments in Europe in an interannual wayand wants to continue pushing leading the functions of AI. In China, its AI approach is different, deeper and more local. There the partner is not Google Cloud, they are national giants like Alibaba (Qwen + Wanxiang), Baidu and Tencent Clouddeepening much more in your Yoyo assistant and hand with Depseek. All of AI One of the pillars of this plan, in addition to the creation of the first agriculture for smartphones, is Aimage. Landing the term to the tangible: the high -end phones of honor process the photographs in the cloud to “improve them”. And about this there are many questions. The first is why. Here Luo Wei states that, historically, Mobile photography has been limited by hardware. A limitation that according to Honor can only be overcome using cloud computing, especially for tasks such as image restoration, provide movement (turn into short video) static images or improvements in the zoom. Being more concrete, 12,500 million processable parameters for its cloud model vs. 3,000 million parameters with which current hardware can deal. Adding to this point the possibility that stresses honor of updating its algorithms via Ota. It’s something we have talked about in Xataka: We have been watching a stagnant industry at the photographic level and with a clear physical limit when improving your hardware. Currently, there are no larger sensors. The second point is in the democratization of functions such as Super Zoom (Zoom improved with AI) on devices beyond its flagship. Creating a cloud platform from which you can drink lower ranges models allows you to honor an experience similar to that of a high range in cheaper models. “The algorithms have been increasingly improving since December last year, when this function had just left. And if you compare the future with what is now, five months later, you can see that the cloud -based algorithm is updated every two weeks is becoming remarkably more real.” For honor it is also especially important The improvement margin through updates that allows AI. Honor takes it seriously: they update it every two weeks. The key here is not alone in time, it is in how. System updates can be installed or not, depend on storage space and hardware requirements. Luo says that, using the cloud, they could update the algorithm daily if they wanted and access to it would be immediate. The second great unknown has to do with profitability. Using Google’s cloud sounds good, But someone has to pay it. Here is surprising the transparency of Luo, who explains that honor is still debating what the business model will be and if they will end up charging users or not to use these services in the cloud. Here, Luo explains that honor does not pay for users or requests, but for QPS (consultations per second). In other words, for the ability of users to access the cloud service, and thus their costs do not depend on user behavior. It is, currently, its way of making this business sustainable, although it makes it clear that it is something that is being worked on and discussing internally. Betting everything to the cloud brings an inevitable question, What happens to the privacy of users. Honor explains that its AI cannot be used without prior consent of the user (it appears from the configuration assistant), and secondly, that all photographs that are uploaded to the cloud to be processed are eliminated after being treated. On the future of photography, Luo closes with a metaphor. At the beginning of the history of automotive, the gearbox was manual. Subsequently, it went to automatic changes and, today, We are already talking about autonomous driving. And yet, we still need drivers. For honor, the AI ​​will allow any user, regardless of their degree of skill, obtain the best photograph in any scenario. For expert users, it will be a co-pilot in editing functions, elimination of elements and post-foto work. Image | Honor In Xataka | … Read more

It is a fight to improve the quality of life

by

Throughout the existence of our species, we have given menopause, an unavoidable stage of women’s life, for some bearable, for others more suffered. However, the last decades have served us to learn a lot from female reproductive health, and that learning has opened the door to something that would seem unthinkable: delay and even end menopause. To fight something, the first step is to understand it, and perhaps we are not bad to clarify this concept. Menopause It is the stage that marks the end of female reproductive life, but leads to a series of changes that go beyond the mere end of menstruations. Menopause It usually occurs In women aged between 45 and 55 and is the process marked by the end of women’s reproductive capacity. The term “perimenopause” is often used to refer to the transition period, a period that usually extends several years. During perimenopausechanges are experienced both in the menstrual cycle, which can be lengthened or shortened; and at the level of estrogens produced by these organs. Progesterone production also falls. “Unlike other organs, ovaries experience accelerated aging, with a drastic drop in its functionality that begins in the 30,” explained to National Geographic ZEV Williams, director of the Fertility Center of Columbia University. Menopause not only implies internal changes but also has very palpable effects for those who go through it. Sophocals are perhaps the symptom that we most strongly associate with this process, although all symptoms depend on the case. The List of symptoms Common includes, in addition to changes in menstrual regularity and suffocation, strong or accelerated heartbeat, night sweat, skin redness, or sleeping problems. Changes in the vagina that take pain during sexual intercourse, urine escapes and more frequent infections can also occur. Menopause is not common in the animal kingdom: only a few species reach the end of their reproductive stage throughout their lives, which has intrigued experts for years. Does it make any evolutionary sense? The truth is that we do not know, so there are different hypotheses to explain this phenomenon. One of them is the Grandma’s hypothesis. This hypothesis proposes that living after the reproductive stage could have helped our ancestors to take a role beyond the breeding of the first generation of descendants. That is, allowing grandmothers to take care of their grandchildren or other relatives without having their own children to attend. There are also those who believe that menopause is not due to our evolution but is the effect of our growing life expectancy. While it is true that the human being has a relatively long life expectancy And increasingly extensive, we must bear in mind that throughout history it would not have been strange to see women reaching the end of their reproductive stage. And yes, life expectancy at birth has changed a lot, but the life expectancy fulfilled an age has done it to a lesser extent. For example, in the 1840s, the life expectancy of a person reached at 10 was over 57 years. More than 60 once the 20th. Ending with menopause At birth, the ovules that will give rise to the next generation are already located in the ovaries. We might think that, as it is a limited number of ovules, stretching the amount of menstrual cycles would be impossible, but the truth is that the number of ovules with which it is born gives for several lives, since this number is Between million and two million of gametes. These are disappearing, but it is estimated that during puberty the number of oocytes is about 300,000. Menopause is not a direct consequence of the exhaustion of these cells but of the aging of the organs that house them, the ovaries. The possibility of delaying the aging of these organs opens a way to prolong their reproductive life and their endocrine role. One of the promising techniques in this context is frozen ovarian tissue. This is a technique designed to simplify the process of extraction of ovules in people with cancer who want to maintain their fertility after very aggressive treatments. The technique, still experimental, is based on extracting tissue from the organ, freezing it and then reimpling it, could open the path to delay the menopausal process. According to their developerswhen reimplanting the fabric, this could be reimplanted in successive sessions, gradually lengthening the fertile age of those who decide to submit to treatment. The developers of the technique published last year An article In the magazine American Journal of Obstetrics & Gynecology in which they detailed their proposal. The Rapamycin It is a compound that could help us to delay menopause without going through the operating room. It is a already known drugderived from a bacterium, Streptomyces Hygroscopicusand used in other contexts for their immunosuppressive and antiproliferative properties. Recently, a team led by Williams, tested this drug. The treatment starts from the capacity of this compound to inhibit a protein related to aging, called MTOR. The provisional results of the study They gave rise to optimismbut we would still be in early stages of the investigation. Often if we have wondered if we can do something we also have to ask ourselves if it is a good idea to do so. Or the less ask ourselves, and all this for what? The answer in this case can be as simple as improving the lives of people who are going through this stage, whose symptoms can lead to a loss of quality of life and whose consequences may be complicated to fit sometimes. But there is even more. Because trying to stop menopause can also serve us as motivation when it comes to understanding it better, which could lead us to solve indirectly linked problems. For example, we know that the late appearance of menopause It has been associated with a lower bone loss in the elderly, as well as a lower risk of vascular and dementia diseases. Know why it can be of great help when improving the … Read more

What does well and what still does not improve in a mid -range that points high

by

Renewing the mobile without spending a fortune has become an increasingly demanding task. In the mid -range There is more and more competition, and also more demands. That is why models such as Samsung Galaxy A56 They continue to attract all looks: they promise a good balance between performance, camera and autonomy, without jumping to the high range. But the big question is whether they really meet everything they promise. To check to what extent it meets, Mario Arroyo has been using the Galaxy A56 as its main telephone, with all that that implies. “It’s a phone that you probably have on the radar if you want to change your mobile, so to see if it’s worth it, I’m going to show you how my life has been with him after 30 days of use,” he says at the beginning of the video. This model already recently appeared in a face to face in front of the iPhone 16E. But this time the approach is different: there is no direct comparison, but a total immersion in what the A56 offers, with its strengths and its most questionable decisions. One of the key sections is the camera, where Samsung repeats formula with respect to previous generations. Mario reviews his capabilities and puts on the table some deficiencies that begin to be difficult to justify in this range. Is it a lot about last year’s model? In the video there are examples that help you understand it. On the 21st of tests, the performance enters the scene. The new Samsung processor, along with its general optimization, leaves a clear sensation, especially after intense sessions of game or multitasking. Is it going as fluid as promises on paper? Mario does not keep his impression. The battery, as usual in this range, maintains the figure of 5,000 mAh. But the difference is in management, and how that data translates into screen hours and effective load. Here we also find some interesting surprise. And yes, as always, the price ends up being the definitive filter. Because it’s not just about specifications, but what you get in return. In that analysis, Mario does not remain superficial. Exposes what the Galaxy A56 offers and puts it in context with what you can find for similar figuresboth inside and outside Samsung. If you are thinking of changing mobiles and the Galaxy A56 is on your list of options, this video interests you. A month of use for a lot, and Mario has condensed his experience to have a clear idea before making any decision.

Synthetic data is not enough, so Apple wants users to help improve their AI: this will work its system

by

Apple Intelligence is herebut its premiere has not been as brilliant as many expected. The company’s new proposal still has improvement marginboth in English and Spanish. Although it has been presented as a clear sales argument, its impact among people has been rather discreet. The first impressions are mixed And, for now, he has not managed to generate a groundbreaking enthusiasm. From Cupertino they already move to reinforce one of the greatest software bets in their recent history. Among the movements in progress stand out two fronts: The rumored restructuring of the team responsible for Siri, whose improved version has been delayed up to 2026and the creation of new techniques designed to improve their language models, with the mission of not neglecting their approach to privacy. One step beyond synthetic data Apple usually training its models with synthetic data and data labeled by humansa solution that has been effective to some extent. It does not always represent the real world. Consequently, it limits the functioning of AI products. This has led the technological led by Tim Cook to develop a new solution that combines synthetic data with anonymous signals of participating devices. As explained in an article published this weekeverything begins with a synthetic message, that is, an email invented by Apple itself with a format that simulates the real emails. For example: “Would you like to play tennis tomorrow at 11:30?” From there, several variants are generated that change some elements, such as sport, schedule or tone, to try different possible structures. These phrases are sent to a part of the devices whose users have agreed to share analytics with Apple. There is something key: each iPhone, iPad or Mac Take a handful of real emails transformed into Embeddings local, that is, mathematical representations that convert each message into a set of numbers that reflect their theme, style and length. The important thing is that these emails never leave the device. Thus, the system compares Embeddings synthetic, which Apple has previously generated, with the Embeddings Real emails, to see which ones are more similar. This resemblance is reduced to an anonymous signal, a simple “this version coincides better”, which is sent to Apple without revealing the original mail or the Embedding of the user. With this, Apple intends to learn which synthetic variants better reflect the real use of language, but without seeing a single fragment of private content. The idea is that this helps improve Apple Intelligence functions such as email summaries or writing tools. This approach is based on the same differential privacy techniques that Apple already uses in other functions such as Genmoji. In that case, the company collects anonymous signals about what Prompts They are more popular, such as “a dinosaur with a hat”, to improve the results without registering which user made what request. The idea is simple but very interesting. Improving without using user data data allows you to maintain the privacy approach that the company has been defending so many years. This new technique will begin to be implemented in the next betas of iOS 18.5, Ipados 18.5 and Macos 15.5. It should be noted that only those who have activated the option to share analytics from the privacy settings are activated. So, if you don’t want to be part of this system, You can deactivate it whenever. You just have to go to Settings > Privacy and safety > Analysis and improvements and deactivate the option “Share iPhone analysis”.

How to improve Chatgpt’s privacy preventing what you write is used to train artificial intelligence

by

Let’s explain How to improve Chatgpt’s privacydeactivating the option with which you allow OpenAi to use all the content you write or believe to continue training its artificial intelligence models. It is an option that is activated by default in your profile, but it is easy to disconnect. When you are using chatgpt, if you don’t change anything you are giving the company permission to collect your interactions. Then, these questions that you have asked the AI ​​and the answers generated for you will be used in the future to continue training and improving the models. But if you don’t want this information to be used because it is private, we will tell you how to deactivate it. Disable data sending to chatgpt The first thing you have to do is enter the configuration of Chatgpt. For that, on the mobile click on the side options button and click on your username. In the web version click your profile image and choose the option of Configuration which will appear in the window that opens. If you are on the mobile, what you have to do once you enter the configuration is click on the option Data controls that will appear in the section of Accountwhich is the first to see above all. Once inside, deactivate the option Improve the model for all That will appear in the first place. With this, your content will no longer be used to continue training OpenAi’s models.

A youtuber has wondered why movies always improve in black and white. The answer: “Less distractions”

by

The tendency to move black and white some successful films looks like a fashion more than a hollywood desperate for repairing and selling our favorite films several times. In some cases, however, the results are surprising, and there is an explanation for this: why in virtually all cases the black and white versions of films that were shot in color are so interesting, when they do not directly improve the original? Blanquinegros dinosaurs. It is the question that Youtuber Midday Reviews was asked when he checked for the umpteenth time one of his favorite films, ‘Jurassic Park’, This time in black and white. He discovered in her, thanks to an experiment that did not believe that he was going to take him to any interesting conclusion, a completely new film, one that returned to the terror to the saurios he experienced when he first saw the film, in the cinema and being a kid. The reason: less distractions. According to the author of the channel, this improvement is summarized in one point: the absence of color distracts less, and the viewer focuses unconsciously on planning, textures, lighting, microgest of interpretations. In aspects more linked to film creation, and therefore in black and white movies have a more “cinematographic” appearance. Not only because they are backward for times when films were less naturalistic and more focused on cinematographic language, but because the absence of color makes the spectator more aware that he is watching a fiction. Other examples. Midday Reviews reviews multiple examples of recent films that have received this treatment commercially, such as’Mad Max: Fury on the road‘(that George Miller himself considers The best version of the movie) either ‘Logan‘ (that He was born as an experimentbut that fans and director think that it is the definitive version of the film). Also mentions a case of which We have talked here‘In search of the lost ark’, a completely unofficial experiment, but that reaches the same conclusions as ‘Jurassic Park’: without distractions derived from color, background aspects such as edition or planning shine throughout its glory. You try. Midday Reviews recommends experiencing with your favorite films, ensuring that you will always find some interest with these colorless versions. And to demonstrate it, it puts some unusual examples: ‘Ninja turtles’ has almost expressionist lighting and planning details; And ‘Solo at home’ becomes an absolutely sinister dyes film thanks to its use of contrasts and that make it a film close to the horror genre. We have done it. Of course we have done it. We have tried an absolute icon of horror cinema: the first ‘nightmare in Elm Street’, overflowing with chiaroscuros, contrasted colors and games with lighting and colors. The result is not only a much more rough film, but completely loses the low -budget air of the Wes Craven classic, acquiring a very classic elegance. Apart from the fact that, as the video says, the lack of color allows you to repair in aspects such as the very detailed and terrifying texture of the special effects or makeup. Is it used for all cases? It will be a matter of testing, but the fun does not take away from you.
