“Life begins on the other side of despair”

by

It doesn’t matter where you are from, how old you are, what you do or what you entertain yourself with. It almost doesn’t matter how you think. Most likely the word “despair” causes you an automatic rejection. Normal, right? In life there are good sensations, others that are debatable, and there are those that are undesirable no matter how you look at them. Despair, anguish, is part of the latter because no one in their right mind would choose despair over hope. No? If we are clear about the above, why the hell in 1943 did the philosopher Jean-Paul Sartreone of the most prestigious minds of the 20th century, had Orestes pronounce the next words in his theater work The flies? “Human life begins on the other side of despair.” The question is timely because, unlike what happens in most literary works, here it does not seem that it is the character who speaks to us. If we take into account Sartre’s philosophy, in this case it is not unreasonable to think that it’s himself who moves Orestes’ lips to express his opinion. Did Sartre really believe that ‘despair’ is the door to life? Isn’t that a discouraging and gloomy panorama? Sartre and existentialism Before talking about how Sartre thought, it is worth knowing who Sartre was, one of the lighthouses of Western philosophy of the 20th century. Thinker, novelist, playwright, critic and political activist, Jean-Paul Sartre (1905-1980) is remembered above all for being one of the great exponents of existentialism. Without it it is difficult to understand the intellectual panorama of 20th century Europe and figures of the stature of Soren Kierkegaard, Lev Chestov, Albert Camus either Martin Heidegger. Although its seams are wide and there are important differences between authors, basically existentialism as conceived by Sartre (atheistic existentialism) is based on a premise: humans are born without a predefined purpose. We are not toasters, cars or TVs, objects created based on a concept and with a specific purpose. Nor are we the work of a superior “craftsman.” Unlike what happens with what we make as men, objects in which the “essence” is prior to the “existence”, in our case it is the existence that precedes the essence. What does that mean? “That man begins by existing, finds himself, emerges in the world, and then defines himself,” the French thinker clarifies in one of his key works, Existentialism is a humanism. “Man, as the existentialist conceives him, if he is not definable, it is because he begins by being nothing. He will only be later, and he will be as he has been made. Thus, then, there is no human nature, because there is no God to conceive it,” Sartre continuesand insists: “Man is nothing other than what he makes himself”, a creature “condemned to be free.” We have not chosen to be here. We have not created ourselves. And yet we are responsible for everything we do. It is not lost on Sartre that this scenario can lead to “anguish”, a feeling of helplessness and despair. He is not the only philosopher who addresses the topic (Heidegger and Kierkegaard also did), although it is true that the Frenchman’s work helps us understand how important sensation is. for him Anguish is nothing other than “the awareness of being one’s own future in the way of not being one”, an overwhelming feeling in the face of the range of possibilities that are open to man, radical freedom and lack of answers. This approach leaves behind an idea that is as fascinating as it is overwhelming: man is born with a huge challenge aheadthe challenge of living authentically, assuming your freedom, choosing your course, giving meaning to yourself and making decisions that will have consequences for your entire environment. There is no destination. There are no excuses. It depends on us. “Man will only be afterwards and will be as he has been made. It is nothing other than what he makes himself. If it precedes the essence, man is responsible for what he is”, warns us. “(Fyodor) Dostoyevsky writes: ‘If God did not exist, everything would be permitted.’ This is the starting point of existentialism. In fact, everything is permitted if God does not exist and, consequently, man is abandoned, because he finds neither in himself nor outside himself a possibility of clinging. “First of all, it finds no excuses. If existence precedes essence, the reference to a given and fixed human nature can never be explained. In other words, there is no determinism, man is free, freedom.” “The first step of existentialism is to put every man in possession of what he is and to place upon him the total responsibility for his existence. And when we say that man is responsible for himself, we do not mean that man is responsible for his strict individuality, but that he is responsible for all men,” Sartre continues. Understanding this enormous responsibility and all its implications generates anxiety, but that has no why be negative. The reason? As Orestes proclaims in his dialogue of the The flies This hopelessness does not have to be frustrating or plunge us into inaction. On the contrary. “It is the very condition of their action because this means that they face a plurality of possibilities and, when they choose one, they realize that it only has value because it has been chosen,” illustrates the philosopher, drawing a parallel with the anguish that a general feels when he decides something that will affect the lives of his soldiers. “existentialism is an optimism, a doctrine of action,” claims Sartre, who ends his essay with a warning: those who use despair to attack it do so by “confusing their own feeling with ours.” It may sound like an old-fashioned lesson (Sartre died in 1980), but his words resonate strongly in an era in which we live hyperconnected, among related ephemera in which the need to search for meaning, identity and authenticity is especially felt.

When a mountaineer experiences extreme experiences on the mountain, his brain begins to imagine something: a “third man”

by

Not all adventures have to be successfully resolved to become epic. It happened with what is known as Imperial Transantarcticthe expedition that left England in August 1914 under the orders of explorer Ernest Shackleton with an enormous purpose and not for the faint of heart: cross Antarcticafrom Vahsel in the Weddell Sea to Ross Island at the other end. Due to the harsh conditions at the South Pole, the ship Endurance ended up trapped between ice and Shackleton saw how his plans became complicated until they dragged him into a real feat that took his endurance and that of his colleagues to a limit level only achievable between icebergs, glacial temperatures and extreme exhaustion. The explorer’s feat also served something that he probably did not even suspect: coining the expression “third man factor or syndrome”. Well known by mountaineers and which is, even today, a fascinating phenomenon. “Who is the third person walking beside you?” Ernest Shackleton (left) with Robert Falcon Scott and Edward Wilson in Antarctica, 1902. The phenomenon was described by Shackleton when he recalled the very hard two and a half days during which he advanced—along with Frank Worseley and Tom Cream—towards a whaling station located on the northern coast of South Georgia. The group walked 36 long hours between terrible conditions, with hardly any material and avoiding death. On their shoulders they also carried the responsibility of having to help the rest of their companions from the ill-fated Imperial Transantarctic. Only the three of them, Ernest, Frank and Tom, wandered through the desolate Antarctica, although if someone had asked them how many people made up that desperate entourage, they would probably have answered something different: that with them was another person, a fourth member, nameless, faceless… but undeniable. “I know that during that long and stormy march over nameless mountains and glaciers, it often seemed to me that there were four of us, not three,” the explorer wrote. That common feeling, precise Guardianoverwhelmed the three men who undertook the journey: the presence of a “fourth” that accompanied them. Such an expression must have surprised the poet. T. S. Eliotwho some time later, in 1922, after reading Shackleton’s story, picked up the idea to capture it in his popular poem The Waste Land: “Who is the third one who always walks by your side? When I count, there is only you and me together, but when I look ahead on the white road there is always another walking at your side.” Eliot’s license, which changed Shackleton’s “fourth” man for a “third” was successful and since then we usually talk about the “third man syndrome” to refer to that: the feeling of a ghost companion, a presence that in a way comforts people who face a borderline sensation. Shackleton was not the only one to describe it. Several years after his death, in 1933, Frank SmytheBritish and explorer like him, recounted an experience similar while trying to summit Mount Everest. “The whole time I was climbing alone I had the strong feeling that I was accompanied by a second person. It was so strong that completely eliminated all the loneliness I might otherwise have felt,” the explorer wrote in his diary. So vivid was the sensation that, Smythe explains, at one point during the ascent he searched in his pocket, took out a piece of Kendal Mint Cakebroke it and turned to offer one of the halves to that companion who felt so close. He didn’t see anyone, of course. You don’t have to go back that far in time. Not that far. The Madrid mountaineer Fernando Garrido wrote in his notebook the feeling that came over him when, at the beginning of 1986, he spent more than two months on the lonely summit of the Aconcaguaat almost 7,000 meters, to achieve the altitude survival record. “Today, like other times, I woke up with the feeling that there was someone outsidenext to the store. Have you spent the night there? Why didn’t he call me to let him in? (…) —said the mountaineer in statements collected for him The Confidential—He’s my brother, my brother Javier! Javi, wake up, come on, wake up! I turn it towards me. “He is dead, his head is a skull.” “A solid science” A good handful of articles and references have been written about the phenomenon, some in media within the reach of Guardian either NPRand in 2008 the writer John Geiger dedicated a monographic book to him, ‘The Third Man Factor: Surviving the Impossible’ after spending five years tracking down similar stories. It is more complicated than collecting experiences, however, to give them a plausible explanation. Years ago, during a chat with the journalist NPR’s Guy Raz, Geiger reported that there are those who turn to spirituality, although he insists that the syndrome can be explained by “a solid science”. “Many skeptics and non-believers have had this experience and attribute it to other causes,” claims the author, who in his volume even includes the case of a 9/11 survivor. In 2009 Geiger pointed out explanations such as biochemical reactions or simply failures in brain activity. “If we understand that the third man factor is part of us, like adrenaline is… then we can access it more easily. It is not a hallucination in the sense that hallucinations are disordered. This is a very useful and orderly guide,” he reflected. Years ago, researchers Ben Alderson-Day and David Smailes commented on the phenomenon and they explained that “strong feelings of presence” do not occur only in dramatic circumstances. Cases have been recorded after bereavement, during sleep paralysis or in cases of neurological disorders, such as Parkinson’s disease or brain damage. “The different contexts in which they occur give us some clues about what could be happening,” they say. “Understanding more about how and why felt presences occur has the potential to tell us many things about ourselves: how we react under intense mental or physical stress, how we deal with danger and threat, … Read more

beaches destroyed and unusable now that the season begins

by

Now that the rains have lost relevance and everything is, little by little, returning to normal: Andalusia is beginning to realize that the winter storms have left much more than accumulated water: they have left a much more uncomfortable truth than the community is willing to accept. Because now Easter is coming and the “Andalusian paradise of sun and beach” has become a succession of destroyed promenades, damaged infrastructure and stretches where the beaches are completely missing. It’s something we knew and didn’t want to see. It is something that the storm is going to force us directly. What has happened? The first part of the story is simple and we have repeated it many times: trains of storms, persistent rains, water systems at the edge of their capacity. But also bad sea, wind and huge waves. As a consequence, while we were all 100% aware of overflows and reservoirs, several provinces have seen how the loss of sand and damage to coastal infrastructure became our daily bread. Huelva, we have already talked about ithas taken the worst part. And yes, the Andalusian Parliament has asked the central government (who has powers in the Coasts) for “stabilization, protection and restoration” works through emergency means. But even if they arrive, that will only be a temporary arrangement. The Andalusia that also lives off its coasts. Beyond the stereotypes, there are many Andalusias. And yes, one of them (or several) lives off its coasts. In 2025, without going any further, tourism broke his own record of visitors and income: we are talking about 37.9 million visitors and more than 30 billion. Now the calendar is tight and the problem has become evident, but the urgency cannot make us forget that it was there from the first moment. Because? As experts remember, the profile of the beaches “it constantly changes in response to changes in transverse sediment transport produced by marine dynamics, especially waves.” This “has never changed in all of history”, what has changed is that in recent decades it has begun to matter to us. How much we have changed. Well, because the emergence of mass tourism starting in the 1960s turned beaches into a very valuable resource and filled them with investments, infrastructure and capital. When the beaches began to change, we applied brute force: as we have explained on more than one occasion“the construction of breakwaters, the annual filling of beaches and the construction of coastal infrastructure to ‘secure’ the line have been the daily routine of our relationship with the beaches.” And as we have more and more investments in them, the problems become more critical and, for this reason, it is more expensive to insure these investments. But we can’t. It’s a race to nowhere; because, nowhere, can we answer the big questions left by the storms: will we be able to withdraw from the eroded front line in an orderly and fair manner? Will we be able to convert that tourism into something that maintains jobs, families and population? Will we be able to understand that behind these rains lies an entire country with a huge problem or will we continue as before?

Apple begins the reconquest of China thanks to the strong point of the iPhone 17 Pro: it is orange

by

Color psychology is a tremendously studied field. Something as simple as a color can trigger feelings subconsciouslybeing the use of green color in the scenes of the villains of classic Disney one of the best examples. It also depends on our languagebut I feel such a powerful weapon, it is evident that it is used consciously in the marketing and colors of the products. And there is nothing that exemplifies it better than China’s fever for the iPhone 17 Pro. For one in particular: the orange iPhone. In short. China is a market with immense potential for companies that want to exploit it. They are simple numbersand Apple has just witnessed what happens when they hit the key. How do they count in Financial TimesIn Apple’s recent financial presentation, Tim Cook welcomed the rebound in iPhone sales in China during the fourth quarter of 2025. The last and first sections of each year are the strong points of an Apple that usually launches its new devices between September and November of each year, but in the last quarter of 2025 they have experienced something unusual: income of 26,000 million dollars, marking a growth of 38% year-on-year in China and accounting for a fifth of the company’s total income. Taking into account the continuity in terms of specifications and fierce competition with Xiaomi, Alive and one Huawei that has returned on its ownit’s… curious. But it seems that the person responsible is none other than one color. cosmic orange. It is the model we analyzed, clearly the most striking of Apple’s colors for the latest batch of iPhone and the one that is causing a stir in China. Orange is a color that distills energy, happiness and vitality. It is a warm color, and in China it also has a meaning positive related to the vitality of the crops, but also with spirituality and with the association of “orange” and “success” due to the similarity in Mandarin. And it seems like a joke, but it’s not. As we said, the colors of a device are not chosen at random, and this one has also landed on the right foot in the Asian giant. Nabila Popal, research director of the analyst group IDCnotes in the FT that “it sounds simple, but iPhone sales respond to obvious external changes in the design, which include the introduction of a garish orange color.” Viral. But it is no longer that Chinese consumers are buying the orange iPhone because it symbolizes that vitality, but because it symbolizes status. The shade of Apple’s ‘Cosmic Orange’ is very, very similar to the classic Hermès Orange, a luxury brand with which Apple itself has collaborated on some occasions (for Apple Watch straps, for example). It is something that has made the orange iPhone Pro transcend: from being a premium range phone to a luxury accessory. And of course, it is only in the most expensive model, the Pro, which increases that even more. perception to have a luxury accessory. “Choosing orange means that everyone knows that you are using the latest iPhone. It is a statement of identity,” said an influencer in one of the -many- unboxings of the orange iPhone that are seen on Chinese networks. Beyond color. Aside from the fact that color has had an impact on the sale of iPhones in China during the last period, the interesting thing is that Apple has managed to turn the tables. It has presented its strongest quarter since the first of 2022, the year in which it stood out and which has been followed by three periods of dcadence compared to national competition. Huawei, in particular, was very strong after recovering from the US veto and starting to launch high-end mobile phones again, this time with home-made chips. Apple should not be too amused about calling the orange iPhone “the Hermès iPhone,” but seeing how viral it is, it’s not like this mix of identities should be a headache in Cupertino. Now the question is whether they will start launching other devices and models in orange to try their luck in China… or if they will withdraw it, leaving the color as an exclusive to the iPhone 17. It wouldn’t be the first time. Image | Xataka In Xataka | For Apple, the price of its iPhones was sacred. Until it began to fall into the void in China

Returning to the Moon before 2030 begins to seem like a political fantasy

by

This same week we learned that the Artemis II mission, which was to put humans around the Moon again, it had to be delayed. The old ghosts of the space program, as it is the complexity of liquid hydrogenhas once again been a blow to NASA, which is increasingly closer to SpaceX to delegate part of its space missions. Hydrogen as a cursed inheritance. As a reminder, all the problems with Artemis II have arisen during the general refueling test, since it had to be stopped when a leak was detected in the hydrogen fuel lines. For fans of the show, this sounds awfully familiar. They are faults traced to which The Artemis I mission has already suffered and that seem inherited from the Space Shuttle era. Liquid hydrogen, being the smallest molecule in existence, has an astonishing ease of escape through the slightest imperfection, a situation that has been recently aggravated by the extreme cold on test platforms. The dependence on SpaceX. While the SLS rocket shows signs of technical and budgetary fatigue, with Boeing threatening staff reductions amid this crisisNASA is forced to pivot increasingly toward the private sector. This is where SpaceX meets with open arms. The current plan is complex: the SLS must put Orion capsule in orbitwhich will then be coupled with the SpaceX human landing system (HLS) to go down to the lunar surface. However, the SLS delays put at risk the entire chain of missions that come after such as Artemis III that could go until 2028. It has its challenges. But SpaceX is not completely perfect, since for the Starship HLS to reach the Moon, it requires an orbital resupply maneuver that could involve up to 12 prior tanker flightsan unprecedented logistical complexity. Although Starship also faces its own challenges and delays, different sources indicate that is the only lander contracted with real capacity to operate before 2030. Although NASA has opened the door to Blue Origin for later missions seeking to diversify, today, without SpaceX, the lunar rhythm would collapse. Until exhaustion. While SLS struggles to overcome basic leaks, SpaceX is following its “break things to learn fast” philosophy. By the end of 2025, the company completed its eleventh test flightachieving a key milestone: the smooth and controlled splashdown of the upper stage in the Indian Ocean and the successful restart of the Raptor engines in a vacuum. This flight marked the end of the “V2” era. Now, SpaceX transitions to Starship V3, an even larger and more capable beast, designed specifically to meet Artemis’ payload requirements. But introducing a new vehicle involves new risks and time-consuming certifications. More than a rocket. We often forget that the Starship HLS is not just a transport vehicle; It will be the “home” of the astronauts on the lunar surface for a week, which further marks this dependence. Although it does not stop here, since SpaceX has completed SpaceX recently completed 49 crucial contract milestones for NASA that go beyond propulsion, including life support that will keep the astronauts alive. Although they have also managed to validate the system for the descent of the crew on the moon or the Raptor engines that have demonstrated their ability to ignite after being exposed to the deep cold of space. Dependency is a problem. With the current data on the table, the optimism of 2025 has evaporated, delaying the date of the different missions to return to the Moon. And although the SLS is currently a bottleneck, the immense complexity of the Starship operation, which requires an almost weekly launch chain, is the real wall against which Washington’s political dates crash.

BTS returns after its members have gone through military service. Now the real war begins: get tickets

by

After almost four years of silence, the flagship group of the k-pop phenomenon returns. And he does it in a big way: announcing a world tour of unprecedented dimensions that will travel through 34 countries between April 2026 and March 2027. The announcement was made at midnight on January 13 and marks the official return of the South Korean group after complete mandatory military service of all its members, with a new album scheduled for March that will be their first joint work since 2022. A huge tour. The magnitude of the event transcends the merely musical. The tour will begin with multiple dates in Goyang (South Korea) and Tokyo before traveling across all continents, culminating in Manila in March 2027. The group’s website It also anticipates additional dates in Japan, the Middle East “and more regions”, suggesting that the final scale could be even higher than initially announced. A different panorama. The world of Korean pop that welcomes BTS in 2026 has experienced a radical metamorphosis compared to how they left it in 2022. What was then an emerging phenomenon in the West has been established as mainstream global cultural. When BTS momentarily disappeared, a phenomenon like ‘The K-Pop hunters‘, a film that became the most viewed in the history of Netflix and whose soundtrack dominated the sales charts for weeks. Every day we are more. BTS’s competition has intensified dramatically. Groups like Stray Kids have broken multiple records previously held by BTS: with eight consecutive albums debuting at number one on the Billboard 200 (compared to six for BTS), they have become the group with the most number one albums of any band of the 21st century. Seventeen was the best-selling K-Pop artist in 2025 and his world tour generated $142 million. The evolution of the genre has also transcended linguistic and national borders. Katseyethe global group created through a collaboration between Hybe and Geffen Records, represents this new direction: formed after a selection process that attracted 120,000 applicants from around the world, its six members hail from the United States, the Philippines, South Korea and Switzerland. Her repertoire was documented in the Netflix series ‘Pop Academy: KATSEYE’, and her repertoire is mainly composed of songs in English, aimed at the Western market. And let’s not forget that ‘APT.’Blackpink and Bruno Mars’ Rosé’s 2024 hit, was a best-seller with Grammy nominations. How are the sales? The BTS tour comes amid a deeply deteriorated ticket sales outlook. The last three years have shown that the global technological infrastructure for mass events is facing systematic crises. It all started with Taylor Swift’s debacle with Ticketmaster in November 2022, when the pre-sale of ‘The Eras Tour’ collapsed the system: the platform received 3.5 billion requests on the day of the sale, causing millions of users to be expelled with error messages after hours of waiting. The controversy ended up in the US Senate and Live Nation’s monopolistic dominance in the industry was questioned. Dramas in Europe. The Oasis case, in 2024, showed that Europe was not exempt from similar problems. Tickets advertised at 150 pounds escalated to 355 because of dynamic pricing, and he had to intervene on the issue the british competition authority. In Spain, the most notable cases have been those of Rosalía and Bad Bunnyseasoned with presence of banking institutions giving favored treatment to their clients. K-pop, in short, has not been immune: Blackpink had its own difficulties with the topic, and although the random selection system characteristic of K-pop is fairer, it also generates brutal speculative secondary markets. The strategic dimension. Furthermore, the return of BTS transcends the merely artistic to become a corporate rescue operation. Hybe, the group’s parent company, has seen its position shake during the hiatus of its main assets: the controversy with NewJeans, which we already explained hereeroded market confidence, and the reputational scars are on the table. The ensuing legal battle publicly exposed internal tensions over the treatment of artists and corporate practices. The key is BTS. However, BTS has potential that many of the groups that have continued their legacy cannot replicate. To begin with, they arrived first: they were the ones who transformed K-pop from an Asian niche into a global phenomenon mainstream. They are considered pioneers. But in addition, their fan base has matured economically: ARMYs, as they call themselves, who were 16-20 years old in 2018 are now 23-27, with significantly greater purchasing power. A test return. The BTS tour poses a definitive test for the infrastructure of live music in 2026. Will current anti-bot systems be enough to cope with unprecedented demand? The US BOTS Act of 2016 imposes fines of up to $16,000, and The European Union banned ticketing bots in 2019. But there is much more to take into account, such as international coordination that requires synchronizing not only ticketing technology but also radically different laws, with different regulations for secondary markets, for example. A real challenge that will put one of the biggest musical events in the world to the test.

Here begins the era of visual and interactive AI that you will not want to stop using

by

Today I have asked Gemini twice what it consisted of the three body problem. The first time I asked the conventional Gemini, who after thinking for a few seconds gave me a text answer, well structured but which at first scared me a little because it even included equations. This was what the response looked like: Then I decided to ask Gemini again, but this time taking advantage of the new feature called Dynamic View (Dynamic View). Google introduced this option a few days ago, and here Gemini does not respond in text mode, but visually. This was what the response looked like: So that I could understand that concept, he created a simulation where I could switch between different simulation modes and speeds. And after that, he complemented this simulation with short texts that explained what happens when there are only two bodies (like the Earth and the Moon) and when there are three bodies and the butterfly effect is experienced. The system becomes so chaotic and complex that triple star systems in the universe are unstable. I didn’t understand it as much with the formula, but with that simulation, I did. This is a clear example of where the tables are going in the world of artificial intelligence chatbots. In that future that Gemini proposes, the conversation can become—if we wish— much more visual and interactive. Almost like a game, because by modifying the simulation we can check the effect of that change in real time. It’s easier to “click” and understand the concept, and that, dear readers, is addictive. Google talked about all this in the presentation of the feature last week, explaining how this option “allows AI models to create immersive experiences, interactive tools and simulations, completely generated in real time for any prompt.” Well, indeed, this is how ‘How I Met Your Mother’ ended, although I have hidden the text so as not to spoil that ending for those who have not seen the series. If you haven’t done it, I recommend it 😉 The practical applications of something like this are, once again, almost limitless. One can apply these dynamic views to understand probability theory, to get fashion tips, or to remember how ‘How I Met Your Mother’ ended. Already put I have asked the impossible: explain to me the movie ‘Tenet‘. He tried it with a good visual scheme (the video below shows that interactive response), but it didn’t help me much because I’m afraid that movie is absolutely inexplicable. I’m not saying it: Nolan says it. Visual and interactive summaries take a few seconds to complete and are not suitable for the impatient, but once they do, the truth is that the answers do not disappoint because that interactivity and visual content enrich said answer and make it much more digestible and attractive for the user. It is the tiktokization of AI to make it even more direct. This approach from Google once again demonstrates how strong the company has been for a few months. The Nano Banana phenomenon turned it into a company that finally demonstrated its potential, and both Gemini 2.5 Flash and Pro a few months ago like now Gemini 3 – which certainly seems to be a step above its rivals – have confirmed the optimism surrounding the company. This latest innovation from Dynamic View It is one of the most powerful and disruptive we have seen in the use of AI in these three years, and follows the path that the company has already outlined with the fabulous NotebookLM. Let’s go shopping with ChatGPT Google, of course, is not alone in that effort. OpenAI has been an absolute benchmark in the productization of AI, and with ChatGPT it got it right from the first moment in that user experience that made us want to use the chatbot for more and more things. The company led by Sam Altman has also been putting forward interesting proposals for a long time to be able to apply AI to all types of scenarios, and now it has come up with a new one that is unique these days of Black Friday: a “Purchase Research” mode that goes beyond finding products for us. And it goes further because it does not stick to our initial prompt, but rather asks us about that prompt. For example, I am looking for a 27-inch monitor with 1440p resolution (QHD) that is cheap and for mostly office use. And that’s what I put in the search engine. The surprises came from there, because in that mode ChatGPT does not give you the answer directly, but it asks you some more questions in “survey” mode asking yourself boxes to answer. Preferred connectivity? (HDMI) What budget do you have? (less than 150 euros). Which panel do you prefer? (I don’t care). After these questions, ChatGPT presents some preliminary options on the screen so that you can tell it if its results are on the right track or not (and if they are not, it asks you why, for example by price or features). After two and a half minutes, the chatbot presented an interesting personalized shopping guide in which it recommended me this Philips 27E2N1500L/00 that is 99 euros and that I will probably end up buying. Obviously this OpenAI tool is interesting for users, but also for OpenAI, because it is one more move in that strategy of becoming our indispensable ally for all types of purchases. ChatGPT wants to be a useful shopping assistant that helps us find products… and that along the way give a commission to OpenAI. We already saw it with Instant Checkout, and this is another move that points to that promising line of income for the company, which certainly needs it like eating. But beyond that, the Purchase Research mode is another good example of how these searches no longer stop at what we ask, but instead ask us questions to better understand what we want and then give … Read more

That a teenager begins to ‘hate’ his parents is something that is in his brain, and science has already found the pattern

by

If you’re a parent of a teenager, you know: their world revolves around their friends. If you were one of them, you surely remember: parents’ opinion took a backseat. And although it seems that it is a sign of the rebellion that we see normal at this age, the reality is that the guilt is literally found in the brain. The culprit. But when asked what causes this indolence among adolescents? The answer comes from the magnetic resonance imaging that has been applied to the brains of some adolescents. And research shows that, during adolescence, the brain not only changes its interest, but also reconfigures your reward circuits so that the voices of strangers are more gratifying than the voice of one’s own mother. And this is something that explains the fact that adolescents give much more importance to a friend than to their own closest family, and even go so far as to prioritize them above anything else. Although in the end he has a good excuse in his brain systems. The study. To find this out, the researchers didn’t have the teens listen to scolding. They used a more cunning methodology by gathering 46 children and adolescents between 7 and 16 years old who were exposed to listening to recordings of nonsense words such as teebudie-shawlt. The important thing about this investigation was that these meaningless words were spoken by two voices: that of their own mother and that of two women unknown to them. In this way, when the recording was played, the activity of their brains began to be analyzed through functional magnetic resonance imaging (fMRI) to see the parts of the brain that were lighting up with each of the voices that were playing. The results. In the youngest children between seven and twelve years old, their mother’s voice caused a party at the reward centers of the brain, specifically in the nucleus accumbens (NAc) and the ventromedial prefrontal cortex (vmPFC). The interesting thing here is that this activity was much greater than what was felt when hearing the voices of the strangers and it is logical because the mother is the center of her social universe that causes her greater happiness. But things change completely in adolescents between 13 and 16 years old, where these same reward and social evaluation regions showed significantly greater activity for unfamiliar voices than for their own mother’s. In this way, the age that we can consider as a border between them paying attention to their mother and when they are going to completely ignore what they are told will be around 13.5 years. Because. In this case we are not talking about adolescents rejecting their parents, since in a behavioral test they were able to identify mothers’ voices in an almost perfect way. The change is precisely in the valuation of that voice. This neurobiological turn is considered an adaptive process essential for maturity. The teenage brain is being “refreshed” for a new mission: leaving the nest. To prepare for independence, the brain must begin to find new social connections more rewarding. You have to tune in with your companions, future allies and partners. The bibliography. This finding fits with previous models that were made to identify the differentiated stages in social and brain development, where the affective focus passes from the mother to friends and finally to romantic relationships. Recent reviews reaffirm that the reward system in adolescence is especially sensitive to novel social stimuli, and that the maturation of frontostriatal connections modulates these changes. A previous work by the same group had already shown that in childhood the maternal voice has a privileged response in the mesolimbic circuit and the current study extends and completes that model by showing how this pattern is reversed in adolescence. In this way, every time we see a teenager who literally tells his mother that he doesn’t even want to hear her, but spends all day talking to his friends, we already know why: his brain has changed so that he likes it more.

The agreement with the US seemed to pave the way to Nvidia in China. Now is the Asian giant who begins to close the door

by

The agreement with Washington had allowed Nvidia sell again Your H20 chip In China. It was a door that opened after months of restrictions. Now, the Chinese authorities have begun to close it slowly: According to Financial Timesand Reutersthey have summoned Alibaba, Bytedance, Tencent and other companies to explain why they buy H20 instead of using local processors. The gesture is not symbolic, several of them are rethinking their orders, and the new scrutiny comes while Beijing encourages a prioritize domestic alternatives. Nvidia developed the H20 in direct response to the export limitations that the United States imposed at the end of 2023. For a time it was its star product for Chinese clients, until this year it was again blocked by a new Washington decision. In July 2025, the veto rose after an agreement with the Trump administration for Nvidia would transfer 15% of the income of some advanced chip sales in Chinaaccording to Reuters. That turn reopened the door, but also unleashed criticism in the United States for its supposed impact on China’s capabilities. A historical agreement that now faces resistance Authorities such as the Ministry of Industry and Information Technology, Mits, people aware of the situation, and the administration of the cyberspace of China, CAC, according to Reuters, have held meetings with companies such as Alibaba, Bytedance, Tencent and Baidu. They have asked them Why don’t they turn to national alternatives and have expressed their disapproval for the use of H20 in government or security areas. They have also raised doubts about the information that Nvidia asks to send to Washington for review. As a result, several companies have begun to reconsider their orders, according to Financial Times, although Reuters points out that it was not ordered to stop shopping. Concerns are not limited to preference for local chips. The Internet regulator asked NVIDIA to clarify whether H20 could involve risks for Chinese user data, including the possibility of “backdoors.” In this sense, Beijing has expressed concern for functions such as remote shutdown or location tracking. Nvidia, as we have seen before, He denies these capacities and argues that H20 is not a military product or for government infrastructure. According to Financial Times, Huawei, Cambricon and other Chinese manufacturers have increased their presence in the market since the H20 was subject to restrictions. Beijing has reinforced the message of technological self -sufficiency and encourage large platforms to opt for local suppliers. Now, it is no secret that the lack of access to advanced manufacturing equipment, Like the latest generation lithography, it is still an obstacle. Despite this, the demand for national chips grows thanks to political support and the need to reduce external dependence. But not everything plays in favor of the local giant Huawei. Great Chinese technology, such as Tencent, Alibaba or Bytedance, continue to prefer Nvidia GPUs For its greatest performance and, above all, by CUDA, the parallel programming platform of NVIDIA that allows the most of its GPU for artificial intelligence and other complex calculations. Replacing it with alternatives such as Cann implies overcoming technical and compatibility barriers. Li Guojie, from the Chinese Academy of Sciences, warns that China needs its own tools that exceed Cuda to achieve self -sufficiency. The great Chinese technology, such as Tencent, Alibaba or Bytedance, continue to prefer Nvidia GPUs. Bernstein, collect ftestimates that the market share of Nvidia in China will go from 66% in 2024 to 55% this year. In parallel, Trump has suggested that he could authorize a Limited version of Blackwell -based processorsthe most advanced of the company. In any case, Nvidia generated 17,000 million dollars in sales in China in its last year13% of its total income. In this environment, each regulatory decision weighs as much as the technological road map itself. What in July was presented as an advance for Nvidia has become an uncertain scenario. Beijing’s pressure, added to the impulse to national manufacturers, redefines the company’s possibilities in a market that was strategic for years. According to the aforementioned means, the outcome will mark not only the future of Nvidia in China, but also the way in which both powers manage artificial intelligence when politics, security and trade intersect.
