Breaking a bad habit is difficult, but not impossible. The key is to make your brain hate it

Habits have a very important role in daily life. In fact, as indicated in the book ‘Emotional Intelligence: Good habits‘ Harvard Business Review, approximately half of our daily actions are based on habits that we repeat without just realizing. However, the same mechanism that anchors good habits, also explains why changing a bad habit may seem like a task almost impossible. It is not only willpower, but to understand how our brain works and how habits are anchored in it. Why do we adopt bad habits? We know that leading a sedentary life is not healthy, that navigating Tiktok video video until many in the morning Take takes the next day and that smoking seriously harms our health. However, such and As explained to Harvard Business Review Judson Brewer, neuroscientist and author of the book ‘Undo the anxiety‘, we cannot avoid falling into any of these negative habits, and eliminating them is very uphill. According to Brewer, the environment in which we live is designed to bombard us with stimuli that reinforce those habits, especially negatives. The rewards that our brain receives when performing certain behaviors alter our Reward -based learning systemso a pattern difficult to break is created. “Every time we try to disconnect from an exhausting task (with social networks), we reinforce the reward, to the point that harmful distractions can become habits.” However, although it is not a simple process, research carried out by Brewer demonstrate that it is possible to change the bad habits definitively. Understanding the response mechanism that articulates them gives us the tools to achieve it. Bad habits have their origin in the way our brain learns through an immediate rewards system (yes, as in Animal training). These behavioral patterns arise because they reinforce the feeling of pleasure or relief quickly. This rewards system implies a trigger (hunger sensation), followed by behavior (eating) and a reward (feel satiated). “These three components (trigger, behavior and reward) appear every time we smoke a cigarette or eat a cake,” says the neuroscientist. Detect the origin of bad habit Bad habits are not eliminated, they are only replaced by good habits. Therefore, one of the important steps of the process to get rid of them is to find the trigger that generates the action to seek the reward. “Once you know your triggers, try to identify the behaviors you make when these bad habits occur. Do you look at social networks instead of working? Do you eat sweets during difficult tasks? You should be able to identify the actions to which you resort to feel comfortable or quiet before you can evaluate your reward value.” For this reason, the neuroscientist ensures that knowing the scenario in which activation occurs and what action is carried out to obtain the reward is one of the key points so that it is easier to eliminate bad habits. For example, eating sweets would be the search for reward that is activated by a situation of stress or anxiety, and sugar rush reward. Avoid or learn to manage the stress situation It is the first step to subtract weight from sugar reward. The key: break the reward chain According to studies of the University of Utrecht (Netherlands), self -control alone is not enough to eliminate a habit, since the brain associates that behavior with a reward that temporarily cancels rational thinking. No smoker will tell you that tobacco It is beneficial for healthbut even so smokes. A fundamental step to break with a bad habit is to reduce or eliminate the reward that the brain receives. That implies not only changing the behavior itself, but also the context that activates it and the associated sensations. Modifying those three elements: detonating, behavior and reward, it is basic for the brain to stop finding satisfaction in that behavior and abandons the need to carry it out. Brewer’s investigations have revealed that an effective way to face bad habits is to replace them with behaviors that offer similar, but positive health or well -being rewards. One of the techniques that Brewer has used with his patients full care training to teach the brain that this behavior is not only benefits, but also represents something unpleasant or even harmfulcausing him to hate him and not look for him anymore. The neuroscientist said that, when someone joined his program to quit smoking, the first thing he asked is to pay attention while smokeing: to the smell, the environment, to the sensation when smoking, etc. The objective of this exercise is that patients become aware of the “value of the reward” and if this value, which probably had positive connotations (social acceptance, etc.), still remains. Studies From the University of Bethesda they have shown that if that reward is no longer appreciated as it used to be, it is less likely that the brain will claim it and, with it, it will be easier to get rid of that bad habit. This can be applied to any other habit that the past may have a positive connotation, but has already been diluted. According to Brewer, an important factor is in question what gives you that bad habit before consuming it and analyzing how you feel before, during and after the process from a critical point of view, instead of simply having a reactive behavior of repentance after having obtained the reward. “Your behaviors may not change immediately, but persevere. If you manage to control your mind with our methods, over time you can free yourself from unwanted habits and see how your cravings disappear with peace of mind,” said the neuroscientist.

It seemed impossible to have a laptop in which to update the graphics card. Until Framework arrived

Framework has just achieved something that gaming laptops users have always longed for: to be able to effortlessly update the dedicated graphics card of the computer. To make this dream come true, the framework company has launched a new version of its Laptop 16 With one NVIDIA GEFORCE RTX 5070 which can be physically exchanged with the previous AMD Radeon RX 7700s in just two minutes. What everyone expected with desire. When Framework presented his laptop 16 in 2023, he promised something that sounded too good to be true. And he assured that he would bring a laptop with modular and updating graphics such as a desktop PC. Today, several manufacturers offer external stations for Cover desktop graphics cards to laptops with the standard Thunderbolt. However, changing the dedicated internal graph of the laptop is another roll. This is the GPU extraction system. Image: Framework Almost two years later, they have fulfilled. As assures The company, the new RTX 5070 offers between 30% and 40% more yield in games compared to the original RX 7700s, maintaining the same 100W of sustained power but with architecture Blackwell8GB of GDDR7 and support for technologies such as DLSS and Ray layout improved. Important technical details. The update is not limited to the GPU. Framework has completely redesigned the cooling system with new fan blades and thermal interface material Honeywell PTM7950, promising better acoustic and thermal performance. In addition, the new graphics card includes a port USB-C Additional rear that supports both video output and 240W feed input. The system also incorporates a MUX switch that allows the dedicated GPU to directly feed the internal screen of the laptop, thus reducing latency. Beyond the GPU. The new generation of laptop 16 includes processors AMD Ryzen AI 300with 8 -core options (Ryzen AI 7 350) and 12 cores (Ryzen AI 9 Hx 370) working at 45w sustained. The motherboard now supports four simultaneous screen outlets through the rear expansion card slots, compared to the previous three. It also incorporates the second generation webcam already seen in Laptop 13, a more rigid upper cover and, as a novelty, a 240W USB-C current adapter. A promise fulfilled. What truly attracts attention is that any owner of the Original Laptop 16 Framework can buy the new RTX 5070 for $ 699 and install it on their current equipment. They can also choose to update only the motherboard (from $ 749) or the 240W current adapter ($ 109). As explained by CEO Nirav Patel to The Verge: “If we found any mass obstacle and we could simply make it work … we want to make sure it is done and working.” Price and availability. Framework keeps the RX 7700S renewed for 400 euros available, although we can also obtain the first generation GPU for 429 euros. The new laptop 16 starts from 1,719 euros in DIY version (without operating system), while a complete configuration with a RTX 5070, 16GB of RAM and 512GB of storage costs 2,748 euros. Although of course, the laptop is very configurable, so the price will vary according to your needs. You can access your configuration page in This link. The first shipments will arrive in December, with the reserves already open. Cover image | Framework In Xataka | Best laptops in quality price.

What is a light year and why it is impossible to travel in less than a year, according to Einstein’s relativity

Among all the rules that govern the universe, one of the most iconic and at the same time difficult to understand is the universal speed limit. The speed of light is not only an unwavering constant: it is the link between matter and energy, as Albert Einstein described with the most famous formula of science: E = Mc². Can Asom to the foundations of our own existencebut not travel to more than “C”. Only light can travel a light year in a year. Let’s define constants: the speed of light The speed of light is the key piece in Einstein’s equation. That “C” is not only a number, but the conversion factor that unites the concepts of mass (m) and energy (e). It is a constant that represents the speed of light in a vacuum, but also the speed limit for the spread of any type of information, signal or material particle in the universe. If you think very strong, it is the limit of causality itself: an effect cannot occur before its cause, spreading at the maximum “C” speed, can reach it. This speed is the same for any observer in the universe, regardless of their own state of movement. If you travel in a hypothetical 99% spacecraft of the speed of light and light a flashlight, the light of that flashlight will move away from you exactly at the speed of light, not to a fraction of it. It is one of the universal constants of physics. And the observations of the cosmic microwave background, The remaining light of the Big BangThey confirm that it has not changed measurable in more than 13.8 billion years. What speed is light, then? Although it sounds strange, the speed of light in a vacuum has an exact and defined value: 299,792,458 meters per second. To put it in more earthly figures, it is equivalent to almost one billion kilometers per hour. A photon of light would go around the earth’s Ecuador about 7.5 times in a single second. It is, according to Albert Einstein’s special relativity theory, the definitive and unwavering speed limit of the universe. An epic about measuring the above Calculating the speed of light has been one of the great sagas of science. After the philosophical debates of ancient Greece and an ingenious but failed attempt from Galileo using lamps between distant hills, the first estimate came in 1676. Observing the eclipses of ío, one of Jupiter’s moons, the Danish astronomer Ole Rømer noticed that they had a different duration According to the time of the year. He deduced that it was due to the additional time that the light took to cross the orbit of the earth when our planet moved away from Jupiter. Rømer estimated the speed of light in 220,000 km/s, a surprisingly close figure for the time. Half a century later, in 1728, the English physicist James Bradley He refined this measure using a different method: the aberration of stellar light. He noted that the apparent position of the stars changed slightly due to the speed of the earth in their orbit. Something similar to how rain seems to fall at angle when we run. From this effect, it calculated a speed of 301,000 km/s, a value with an error of just 1%. Michelson’s experiment. Image | Popular Science (1930) It was not until 1887 that scientists discovered the most surprising aspect of the speed of light. Albert Michelson and Edward Morley tried to detect the “luminous ether”, an invisible half assumption that, according to the belief of the time, filled the space to allow the propagation of light. With Your experiment They hoped to measure a difference in the speed of light depending on whether it moved in favor or against the “ether wind” created by the movement of the earth. However, they found no variation at all. Sometimes, scientific progress does not come from finding what is sought, but of accepting the evidence that hits old certainty. This was how this failure It became one of the most important results in the history of physics. He showed that the speed of light was constant regardless of the observer’s movement, knocking down the ether theory and laying the empirical bases for the revolution that Einstein would unleash later. What is a light year and what is used for Since 1983, the speed of light is no longer something that scientists try to measure with increasing precision. Its value was set with such accuracy which is now the meter itself that is defined according to the light. One meter is “the length of the path traveled by light in a vacuum during a time interval of 1/299792458 seconds.” This change hides a deep truth: the constancy of the speed of light is a more fundamental property of our universe than our own units of measure. We no longer use meters to measure the speed of light, we use the speed of light to define the subway. And this is how one of the largest units of measure we use is born, and that has been crucial to understand the immense scales of the universe. Although your name includes the word “year”, a light year is not a measure of time, but of distance. In a nutshell, a light year is the distance that a ray of light travels in a vacuum during the course of a terrestrial year. That is, in 365 days. Given the incredible speed at which the light travels, it is an astronomical distance, of approximately 9.5 billion kilometers. We use the light years because the distances in space are so huge that measuring them in kilometers would be totally impractical. For example, The exoplanet closest to EarthNext Centauri B, is about 4.2 light years away. In kilometers, that figure would be almost 40 billion, a much more difficult number to handle and contextualize.

Chrysalis, the impossible ship 58 kilometers long to transport 2,400 people to next Centauri

Exodus through space is a recurring theme in science fiction. It doesn’t matter if it’s literature (‘Aurora’), cinema (‘Wall-e‘) or video games (‘Mass Effect Andromeda‘), the idea of a huge ship that transport a lot of people that become inhabitants of a planet on the other side of the universe is as fascinating as utopian. But at some point you will have to get to work, and there are those who have had an idea: a 58 -kilometer ship for Bring Humanity to Alpha Centauri. His name is Chrysalis, and the duration of the trip will be 400 years. Chrysalis project. Within the ‘Project Hyperion Design Competition‘, a group of Italian social engineers, scientists and architects They have designed Chrysalisa ship of about 58 kilometers in length with a cylindrical and multicapa architecture. To simplify, it would be like a Russian, but elongated doll, with a concentric core and layers that would have differentiated areas for: Production. Life. Industry. Storage. Would have artificial gravity achieved by constant rotation of the entire cylinder and the idea is that it can transport 2,400 passengers to Next bthe most promising exoplanet of the system. There they would disembark and could start colonizing the territory after a 400 -year trip. Estimated construction time? 20 to 25 years. Layers. It would be like a huge city and remember The Line, the Saudi Arabia macroproject. Throughout those 58 kilometers and depending on the layer, areas destined for food production, forest biocservation, community areas with parks and facilities such as schools, hospitals or libraries, as well as habitable modules, industrial areas and an external ring dedicated to storage. The heaviest jobs would be operated by robotsand it will not be the only thing, since the plan includes a combined governance between humans and artificial intelligence. No cryogenization. Something that we usually see in these science fiction works is that the crew criotic so as not to die during the trip, but in the case of Chrysalis, there would be no option. Throughout those 400 years, several generations will pass, being a task for all those that fail to reach the goal. To avoid tensions due to the shortage of resources, births would be controlled to the millimeter, maintaining the population within the sustainable limit that the installation can provide. Recycling is contemplated as a vital option and, to give energy to the entire complex, nuclear fusion reactors will be used. Crew preparation. In addition to the fact that everyone who embark on Chrysalis will not see their new home on the mainland, it must be taken into account that virtually no one of those who embark on the mission at first will set foot on the ship. The reason is that it is estimated that one of the most crucial part of the trip, also the most radical, will be the preparation for it. In addition to having psychological support and having a careful strategy for 2,400 people to live in such an environment, before leaving the training will be given for 70 or 80 years In Antarctica. That first (and almost second) generation will face the conditions of isolation and extreme confinement that they will experience during the journey. It will be part of the second and third generation that, finally, are on their way to next Centauri b. Housing modules. There would be one and two floors Do not make illusions. Now, the ‘Project Hyperion Design Competition’ is an initiative with an objective: to seek a spacecraft capable of taking some thousands of humans to a habitable exoplanet In an interstellar trip of several centuries, so it is only a conceptual project for several reasons. The first could be ethical, since training will be devastating and, in essence, the entire trip is an evolutionary experiment with a large -scale controlled population, which means this Mental health levelidentity and perception of time. The second … because the technology to make it reality escapes our understanding right now. Only the fact of need Fusion reactors (that We are investigatingbut we have not yet developed), leave this experiment as something exclusive to the science fiction field.

It is impossible to make money with her

One of the things they have achieved, in quotes, the LLMS is bring the programming closer to users They don’t know how to program. It is no longer necessary, again, in quotes, to know programming languages to do simple things, but it is enough to give natural language instructions to a model and let it do its magic. This is what we know as Vibe Coding And there are startups dedicated to it, see Windsurf (now owned by Openai) and Anysphere, the matrix of Cursor. The problem is that the accounts do not come out. How does this work. Companies such as Cursor, Windsurf and Replit have become famous for the Vibe Coding. Basically, these offer access to a programming platform that, in the background, is based on the models of large companies of AI. In other words, Anysphere charges the user a subscription for accessing cursor and, in turn, pays Google, Anthropic and Openai for accessing Gemini’s API, Claude and GPT. Money, money, money. The problem that this business model has is that many costs do not depend on startup itself. On the one hand, AI companies are refining their new models to program better, See GPT-5. These models, in addition, are generally more expensive as we will see later, but the Vibe Coders They love them because the results achieved are better. Thus, the startups of Vibe Coding They are in the position of having to offer the best models (and therefore, the most expensive) without raising the price of the subscription and, at the same time, competing against the companies that create these models and that also have their platforms of Vibe Coding. Let’s think, for example, Claude Code (Anthropic) or Codex (OpenAI). In short accounts. When the product depends practically completely on third -party models, a change in the price structure can cause the startup not to face the costs. This is the case of Windsurf, a company Vibe Coding which was sold to OpenAI for 3,000 million dollars and that, according to slide from TechcrunchHe had very negative gross margins. There is an entire industry based on the idea that the prices of the models will go down, but the reality is different, at least for the moment. Prices of the latest Anthropic models | Image: Xataka The models are expensive. Accessing the Google, OpenAI and Anthropic models does not come out cheap. To give some data, and based on the basis that one million tokens are more or less 750,000 words, more than the three books of ‘The Lord of the Rings’: Opus 4.1 (Anthropic) It has a price Input/output of 15 and 75 dollars per million tokens, respectively. It is one of the most expensive models, but the most used to program thanks to its good results. For prompts of up to 200,000 tokens, Gemini 2.5 Pro (Google) It has a price Input/output of 1.25 and 10 dollars per million tokens. GPT-5 (OpenAI) It has a price Input/output of 1.25 and 10 dollars per million tokens. Openai has thrown prices with its new model, since GPT-4.1 cost 3 and 12 dollars per million tokens. If a company bases its business model on a subscription of $ 20 per user, it is quite likely to lose money with each of them. The best proof of this is the recent Pro change prices for cursorwhich since June 16 offers $ 20 per month of use of the large models of the invoices of API rates. Until that time, users could access 500 quick responses from the best models. The background reading is that offering broad access to the best models to program AKA to Opus 4.1 does not go to accounts. The options. The most obvious option is that the startup develops its own models to program, something that is neither easy, or fast. Moreover, these models would have to offer capabilities equal to or higher than those of OpenAI and company, companies with many more resources to iterate and improve rapidly. This would not be viable in many cases, but in the long run it would have a positive impact on costs. In that sense, Anysphere, the company behind cursor, is already working in Fusion, its own model. The second is to entrust to the idea that the price of AI models will go down over time, something that, for the moment, is not happening in general. OpenAi has taken steps forward With the launch of GPT-5whose price, as we saw before, has been reduced considerably. However, the trend is rather the opposite. Gemini 2.5 Pro and Claude 4.1 They are, without a doubt, models more expensive than their predecessors. The only exception, for the moment, is GPT-5 and we cannot do anything other than expect to see how prices evolve.

Taking spectacular photographs of the Perseids seems impossible. NASA has a guide to demonstrate otherwise

The Perseids are already here and, although there are still a few days to reach their peak of activity, it is convenient to keep in mind some clues and tricks if our intention is to capture them in a photograph. Because as more than one will have proven, this is not always easy. AND Who better than NASA to point to any of these tricks. The first step: plan. If we want to get a good image of this rain of stars, the first thing is to think where and when. The Perseids or Tears of San Lorenzo can be seen for several weeks of summer, approximately between June 17 and August 24, and reach their peak of activity around August 11 and 12. Where and when it is also important when it comes to circumventing the great enemy of astrophotography: light pollution. First, it is convenient Avoid full moon And the phases in which it reflects the most light, since, although we do not perceive this light, it reduces the contrast that our eyes require to see the fleeting stars. It is also important flee from light pollution that generate the lights of cities and other settlements, so perhaps we should plan a trip to the field if we want to see these stars. Finally, we must also know where to look. Perseids owe their name that seem to radiate The constellation of Perseus. Knowing how to locating this constellation in the sky is very useful when restricting the angle to which to aim the objectives of our cameras and increase the probability of capturing some of these flashes. Second step: the team. A tripod can be helpful. Photography will require a long exposure. Maybe they are just a few seconds, but our pulse or any other involuntary movement could spoil a perfect shot. If we do not have a tripod we may resort to a “homemade” solution, such as supporting our camera on some rocks, but that will subtract maneuvering capacity. It can also be useful pertrech In order not to have the chamber trigger and thus avoid additional vibrations, but we can also dodge this requirement with the camera timer. Regarding the lens, NASA’s recommendation is in angular. Since we do not know when and where the next flash will happen, it will be best to cover a lot to increase our chances of success. Third step: Prepare. Once in position, we can start looking The constellation of Perseus. Orient our camera towards it will increase the chances of capturing the flashes of this rain of stars. The approach, best manual. The reason is that cameras self -effect systems can be lost in night darkness. Since we will not have to change the focal point, this does not imply any problem once we have taken the ideal approach. We will have, of course, to walk with an eye: sometimes focusing on infinity is not the best option, so it is a good idea to try small adjustments until you find the ideal approach. There is still a detail. We had said that capturing a rain of stars requires long exhibitions. Calculate how long can also require adjustments, but NASA also has a trick to facilitate work: Rule 500. It is about dividing 500 by the focal distance of the lens, and using the figure as time, in seconds, that our open shutter will remain. This value represents the maximum time that we can maintain the exposure before the terrestrial rotation makes the background stars begin to spread. If we have a 20 mm lens, we will have that 500/20 = 25 seconds of maximum. Experiment, enjoy. Rule 500 can be a good start, but we will still have to adjust our ISO and opening values, which will also allow us to play with shorter exhibitions. We can make small changes and verify how each one affects the quality of the image or its aesthetics. He last advice that NASA It has for those who are encouraged to photograph the persistes (or any other rain of stars) is simple: enjoy. These astronomical events offer us an opportunity to see the night sky in a different way, in advance generated by the unexpected flashes that cross the night sky on some summer nights.

After achieving what seemed impossible, Nvidia sees his future in China threatened by something terrifying: the bureaucracy

What is happening to Nvidia with the GPU to artificial intelligence (AI) H20 It is a real odyssey. Currently this chip is its best asset to protect its position in the Chinese market, but at the current situation it is not clear that the company led by Jensen Huang go survive In this gigantic Asian country. Interestingly, the beginnings of this GPU in China were extraordinarily promising because Their sales grew by 50% quarter to quarter since it arrived in this market in mid -2024. However, everything was complicated for Nvidia in the middle of last April. And is that the US Department of Commerce imposed new restrictions To the export to China of the H20 GPU, which in practice caused this chip to stop reaching the Chinese clients of this company. This news Nvidia’s shares sank 6% in the bag because I could no longer attend the commitments linked to the H20 GPU that it had acquired. At the beginning of July there was another unexpected turn of events. Jensen Huang met with Donald Trump and got something that seemed impossible: the trade department would allow him Sell again in China the H20 chip. Since then four weeks have passed and Nvidia continues to wait. He has not yet received the export license you need to sell this GPU in China, and, According to ReutersThe problem is that the Commerce Department is mired in the bureaucracy, which has originated a delay in the concession of export licenses that has not occurred for more than 30 years. The future of Nvidia in China is in the hands of the Chinese government This delay comes at the worst time for Nvidia. Among Chinese clients who have bought great amounts of this GPU, and that presumably plan to continue doing itare Tencent, Alibaba or Bytedance. But if the Department of Commerce takes much more the delivery of the export license to NVIDIA these commercial operations could be canceled. And it is that Jensen Huang’s company has another very important open front. The CAC is responsible for the censorship and control of the contents published in the network As We explain to you last weekthe administration of the cyberspace of China, usually known as CAC for its English denomination (Cyberspace Administration of China), he has decided Thoroughly investigate the H20 GPU. This institution is the main Internet regulatory body in China and is responsible for the censorship and control of the contents published in the Network, the supervision of technology companies and compliance with the Data Security Law and the Personal Information Protection Law. The problem that Nvidia faces now is that The CAC has decided to investigate it Because he suspects that the H20 chip could incorporate a rear door of difficult location by Chinese experts. If so, the possibility of China to use this GPU could be possible. At the moment the CAC has limited himself to questioning those responsible for NVIDIA in China and ask them to demonstrate that the H20 Chip does not represent a threat to the interests and security of the country led by Xi Jinping. As expected, Nvidia has immediately responded to the Chinese authorities and is collaborating to dissipate as soon as possible the doubts that loom about the H20 chip. According to SCMPthose responsible for the company in China have assured CAC researchers that the GPUs for the develops They do not incorporate any “back door” implemented to facilitate espionage by the US government. “Cybersecurity is of vital importance for us”, has declared A NVIDIA executive. “We have no rear doors in our chips that can give someone remote access or the ability to control them.” Probably during the next few days we will know how this conflict ends.

I’ve been paying Youtube Premium for years and I don’t regret it. The problem is that going back is impossible

I do not know since when I have Premium YouTube, but the first track in my mail is a cancellation notice of September 2018. Spoiler: At two months I went back to discharge. There is something uncomfortable for many people to admit that you pay for Youtube premium. It is like confessing that you have gone to a sophisticated blackmail. But here I am. I keep paying, and I don’t regret it. I took the step after an annoying epiphany: I was watching a long video and interrupted me for the fifth time with an ad. It was not just the discomfort, but The feeling of being manipulated by an algorithm that had calculated exactly how much I could torture me before he left the platform. Google knows that YouTube is a de facto monopoly and acts as such. Youtube premium changed how consumption content. Without interruptions, I can follow long documentaries without losing the thread. The platform was a library of knowledge again, not a sequence of advertising cuts. The creators who continue to charge more with my subscription than with ads. And as a gift comes YouTube Musickilling two birds of a shot: perfect to solve The Garminoblivious to Apple Music. The model is perverse but effective: degrade the free experience to make it annoying and then sell the solution. It works because YouTube has trained a whole generation to tolerate constant interruptions. We have normalized to cut our thought Every three minutes. But here comes the most insidious: Premium is an entrance drug to an interruption without interruptions. Once that experience tests, go back it becomes impossible. Google knows it. They have hooked not only to their content, but to their version of digital comfort. That accumulated time and constant interruptions are worth more than what the subscription costs. Each announcement avoided is time that I dedicate to something that really interests me. Pure self -defense in an economy that monetizes our attention. I’ve been paying for years and I will continue to do so. Not because the system seems fair to me, but because I have decided that my mental tranquility is worth more than my resistance. In the era of digital monopolies, this is the closest thing to freely choosing that we are going to get.

We thought that there would be no going back in the supremacy of AI. Then some kids arrived and an impossible test

There is a place in the world where some of the young brains meet every year brighter on the planet. Not everyone goes for the medal: some just want to solve six problems that could despair more than one doctorate. It is the International Mathematics Olympiad (IMO), a competition that demands a highly capable mind. Until now, it was a land reserved for humans. But this year, two of the most advanced artificial intelligence models – developed by Google Deepmind and Openai – decided to enter the board. They achieved the unthinkable: A gold score. Even so, something unexpected happened. A handful of students managed to overcome them. And that has revived an inevitable question: will this be the last time someone achieves it? Machines gain ground. Until now, no artificial intelligence model had reached that brand in the IMO. Deepmind had stayed at a single point in 2024 with 28/42 points. This year everything changed. His new AI – an unpublished version of Gemini Deep Think– Solved five of the six problems in natural language and within the official limit of 4 hours and 30 minutes. Openai’s prototype matched the feat: 35/42 points. Gold, finally, is also a matter of machines. Even so, both of them were blank in problem 6: 0 points. {“videoid”: “x8jpy2b”, “Autoplay”: fals, “title”: “What is behind it like chatgpt, dall-e or midjourney? | artificial intelligence”, “tag”: “Webedia-prod”, “Duration”: “1173”} They made history, but they did not win. The results sheets revealed that 26 human students exceeded the two AI. Alexander Wang, a young American, reaped his third consecutive gold with 37 points. But the brightest were read Deng and Hengye Zhang, from China, who signed perfection: 42 of 42, including the dreaded problem 6 that the machines did not solve. Problem 6 raised a 2025 × 2025 boxes. A agreement with Aops onlinein general, the task was to place rectangles – of any size, always aligned to the grid and without overlapping – so that each row and each column has exactly a free box. The question was how many rectangles are needed to get it. NATIONAL RESULTS. With 231 points, China recovered the first position of the medallero – United States obtained 216 and South Korea 203—, According to official results. His six representatives hung the gold; Two of them reached 42 points. The rest added between 35 and 40. As SCMP points outamong them is Qiming Xu, who achieved 36 points competing with cerebral palsy. Above, the Chinese team that led the medal. Below, the American team that was second Rival or tool? Research teams insist that they do not seek to replace students. Thang Luong, leader of the Deepmind project, assures the Wall Street Journal that Its model can be “a new calculator for the next generation of mathematicians.” The reality is that the qualitative leap is enormous: to need days of computation and formal language in 2024, to generate legible evidence in hours. That improvement raises a new scenario for schools and competitions. The last human victory? Alexander Wang believes that in 2026 the AI will already resolve the six exercises; Qiao Zhang sees it to fifty percent; And Thang Luong himself believes this could be the last IMO with human advantage. Not everyone is convinced. Former Midralist Junehyuk Jung – a researcher at Deepmind – argues that problems such as 6 will remain out of reach of the models “at least for a decade.” In Xataka Jensen Huang, CEO of Nvidia: "I have created more billionaires in my management team than any other CEO in the world" For now, teenagers leave with more than a medal: the certainty that, for the moment, human intelligence still resists. 2026 will say if that margin disappears or if they bend the pulse to the machines with pencil, paper and an idea that no one had planned.

Ouigo wanted to enter the Madrid-Galicia AVE but he already sees it impossible before 2030

“We have no problem in competing (…) but whoever wants to come, to make the investments that it has to do and that competes on equal terms” Thus, Álvaro Fernández Heredia, president of Renfe, in the past Executive Forum where the manager approached the open door for the competitors of the trains company in Spain to take the first steps to reach Galicia, has sounded. Galicia. Renfe has entered the line between Madrid and Galicia. Although the company has had to face criticism for Do not meet the expected times and skip some stops in Zamora To reduce travel times, the Madrid-Galicia axis is working very well to the company. Only a few days ago we knew that Renfe was taking more travelers than ever. A semester of record in which this line has been key, where the train has begun to make shadow even the plane because it has better time connections if you want to travel in the day or make night and return to the origin early in the morning. The competition. A few months ago, Adif launched the Second package in liberalization of high -speed tracks. The runners are Madrid-Galicia, Madrid-Asturias/Cantabria and Madrid-Cádiz/Huelva where Ouigo, Iryo or any other company can present Renfe battle. However, this It is not expected until the next decade Because there are no trains available. Talgo has already compromised all its production of the Avril trains that work there and is aware of which roads the new owners of the company will take. This has caused a bottleneck impossible to solve if it is not renting the company’s rolling material. According to The reasonOuigo would have contacted Caf and Talgo to buy the trains but they are already committed. The only solution is to rent Renfe’s rolling material. “And if possible”. This possibility has been completely denied by Fernández Heredia, president of Renfe, with the words mentioned above. But not only that, the manager has launched a dart to his competitors, although he has not mentioned them directly, emphasizing that the one who enters the corridor will have to “compete in equal terms. And if possible, not to losses“ Public Service. Renfe’s dart is not causal. The company has long accused Ouigo of operating at losses in Spain and although the French company ensures that it is the usual strategy when entering a market and that they foresee short -term profits, the government has reached Threatening to report to the French before the European Commission. Renfe, unlike the French or Iryo, have the obligation to operate in some lines as a public service, which he weighs his results account. A good example is the Oscar Puente lamentMinister of Transportation, following his obligation to pass through Extremadura, emphasizing that this way of acting does not guarantee clean competition. More liberalizations. Renfe, for the moment, seems to be insured by the Galician corridor. The problem of the lack of trains is that anyone is worth it. Vehicles are needed that can change between Iberian and international width. This peculiarity leaves Renfe as a competitive advantage because he has some Avril who, Although not exempt from problemsnobody has. But also, Spain has to face new liberalizations very soon. Among them that of Cercanías, a very controversial area because these services are of public obligation. Only in its public services (nearby, medium distance, metric width and Avant), Renfe moved in the first semester of 2025 to 259.5 million passengers.
