The state of the ISS is so alarming that the United States and Russia have sat at the table for the first time in eight years

by

You have to look back until October 2018 to find the last time that NASA’s top people and her Russian counterpart, Roscosmos, the faces were seen. The launch of the Crew 11 mission has served as an excuse for them to meet again. A meeting to save the furniture. The new general director of Roscosmos, Dmitry Bakanov, traveled for the first time to the United States last week to witness the launch of the SPACEX CREW-11 MISSIONin which two American astronauts, one Japanese and a Russian one flew to the International Space Station. Bakanov took advantage of the trip to meet with NASA’s acting administrator, Sean Duffy. On the table, the future of a space station that ages by leaps and bounds and The road map for withdrawal in 2030. NASA and ROSCOSMOS are needed. In a global context where war and other geopolitical tensions have affected almost all areas of cooperation, the International Space Station and the exchange of seats in Crew Dragon and Soyuz ships remains one of the few bridges standing. But this has been the first high -level meeting in almost eight years, especially since the previous Chief of Roscosmos, Dmitry Rogozin, adopted a belligerent rhetoric against his US partners. According to the Russian state agency TassBakanov and Duffy agreed to extend the shared use of the International Space Station until 2028, as well as a joint process for exorbitation in 2030. “The conversation was quite well,” Bakanov said. The US agency Associated Press He says that both leaders pointed out the need to maintain cooperation in space despite their “strong discrepancies” on Earth. They also agreed to seek the approval of their respective presidents for future joint projects, including lunar and exploration of deep space. The ISS falls apart. This “we have to talk” is not accidental. It occurs at a time when the state of the International Space Station is a matter of “deep concern”, as noted by the NASA Aerospace Security Advisory Panel in April. The Committee described the coming years as “The riskiest period“Of the ISS in all its existence. One of the most serious and persistent problems are Air leaks in the Russian module Zvezdafirst detected in 2019. Despite the multiple attempts to repair them, the module continues to lose air, a qualified problem with the highest level of risk of NASA. To this we must also add other ailments of a structure with almost 30 years components. Lack of spare parts for critical systems, space costumes with technology from the 70s that have caused several incidents, and constant problems with bathroomsamong other headaches. Pension plan. The common denominator of these risks is a huge budget deficit. No government wants to allocate more money to the International Space Station when the priority is to finance future lunar missions and commercial stations. More than a shy thaw, the meeting between Bakanov and Duffy represents the imperative need to jointly manage the last years of the ISS, the largest symbol of international cooperation outside the earth. One of the Keys to this approach It is the contract of almost one billion dollars that NASA awarded Spacex to develop a ship that tow the station towards a safe reentry on the Pacific Ocean. Before Spacex, the ISS partners had considered using Russian progress ships for this task, an option that Roscosos seems to have put back on the table. Be that as it may, the retirement of the ISS already has its date insured by the end of this decade.

Google, Amazon and Microsoft have been burning absurd amounts of money in Ia for years. Finally they begin to see green sprouts

by

The AI boom made Big Tech will increase their capital spending to limits that had never been seen. The fear that The bubble will explode Rondaba, investors They started to get nervous and the profitability of AI remains in doubt. The last results are a green outbreak, the first in a long time, although with many buts. The cloud reaches capex. They tell it in The Information. Capital or Capex expenses of the Big Tech in recent years have climbed unstoppable, much faster than their income, but in the results of the last quarter the gap is finally closing, but not because chatbots and other products are being profitable, but thanks to revenue from cloud services. The crazy one is committed to AI is beginning to show a slight green outbreak, even if it is not directly because of AI products. Income from cloud services are approaching capital spending. Source: The Information (click on the image to access X) The four riders. There are two clear winners of the departure, one that already brought the duties done and one that goes free. Let’s see who is who: Microsoft: The clear winner with a Income increase of 25% In the last quarter, mainly thanks to the growth of Microsoft Azure. Google: Record a 20% increase In your income thanks to Google Cloud and advertising. Amazon: falls 7%but it is the only one that was in positive numbers. Amazon Web Services is the largest provider of cloud services and was already profitable, although its growth is beginning to slow down. Goal: Your income grows 22%but they basically come from advertising. Goal does not sell cloud services, so it does not generate income directly. Indirectly, yes: AI has allowed them Improve the efficiency of your advertising business. Burning money. The increase in capex by AI has reached madness figures that had never been seen in other technological booms. By the end of 2024 we talked about investing a real barbarity In data centers: Microsoft 30,000 million, Goal 35,000 million, Google 25,000 million… The dizziness figures, and have not stopped increasing. Amazon said at the beginning of the year that He wanted to spend 100,000 million in data centers for AI and goal is building several data centers whose combined cost could rise to 200,000 million dollars. Skepticism. This excessive spending frenzy soon unleashed a wave of skepticism. AND If AI is another bubble And is it about to explode? Milmillionaire investments are not translating in income. Even Satya Nadella himself, one of the protagonists of this revolution, was skeptical because At the moment no one is making gold with AI. It is not that they are not making gold, it is that nobody is earning money. In their newsletter, Ed Zitron had accounts And the difference between what is expected to spend in 2025 and the return that is giving them the AI is not that it is a reason to doubt, it is directly no sense: Capex planned in 2025 BENEFITS IN IA IN 2025 Microsoft 80,000 million 13,000 million Google 75,000 million 7.7 billion Amazon 105,000 million 5,000 million goal 72,000 million 3,000 million Green outbreak Yes, in singular. The latest results are hopeful, but we are very far from being able to say that AI is a profitable business, especially As far as generative AI is concerned. Good results are thanks to cloud services, chatbots or audio or video generators are not profitable. Subscriptions to these tools are a way to monetize, but The income they generate is child compared to spending. Despite doubts, unbridled expense has not stopped and this green outbreak can be more than enough for investors to continue throwing banknotes to the AI well.

We knew that living near the sea made us “win” years of life. What we did not know is that it was literally

We have known for a long time to approach nature has benefits on our health. Beyond avoiding the contamination of our cities, approaching the natural environments around us can improve our psychological well -being, perhaps even inciting a more active life. Little by little, we are also observing that something similar happens if we change the mountain for the sea. More sea, more life. A study has observed a correlation between residing in coastal areas and greater longevity. The analysis It provides new tests of the link between the bodies of water and the health and well -being of the people. Of course, the relationship between “blue spaces” and health is a bit more complex than it might seem. 50 kilometers. The study observed that the benefits of living near the ocean improved the quality of life of the people who lived in a strip of about 50 kilometers of the coast. Inside, however, they observed a very different trend: the people who resided in the vicinity of water bodies of a certain size (about 10 km² on surface) tended to hope for short life. “Globally, residents of the coast are expected to live one year or more above the average of 79 years, and those who lived in more urban areas near rivers and interior lakes were more likely to die around 78 approximately. The residents of the coast probably lived longer due to a variety of interconnected factors,” stood out in a press release Jianyong “Jamie” Wu, member of the study responsible for the study. 66,000 census areas. The study was conducted in the United States, where the team analyzed 66,263 census areas, studying life expectancy and its relationship not only with the proximity of water bodies, also with socio -economic and demographic factors to control the results. The details of the study can be consulted In an article Posted in the magazine Environmental Research. Looking for the cause. The team indicates different factors that could mediate this relationship, such as softer temperatures, better air quality, greater number of opportunities for recreational activities, better transport, less vulnerability to droughts, or rent. These factors could explain why residing near the coast is associated with greater life expectancy, in contrast to people who live near interiors. “Contamination, poverty, lack of opportunities to be physically active and a greater risk of flooding are the main triggers of these differences,” Yanni Cao indicatedCo -author of the study. Correlation or cause? It fits remember that the existence of a correlation does not always imply the existence of a direct (not even indirect) relationship of causality. For example, if income is the determining factor, this causal relationship could have different forms. A possible way would start from the fact that coastal areas They would be more expensiveso they would attract people with more rent, being income, a factor we know affects our life expectancy. Another possible way would be in the fact that the coastal areas generate greater income by offering more job opportunities, and these income again would be the determining factor in longevity. In both cases the mediating factor is the same, but the causal relationship does not. In Xataka | Why is it more hot in cities than in the field: the urban heat island effect Image | Emiliano Arano

Western classics 50 years ago

by

Sometimes, the remote areas of the Televisa grill offer more information about our tastes and customs than if we only look at the great successes. This is the case of the thematic chain Thirteen And his very followed noon western, which in the popular imaginary has already replaced “the documentaries of the 2” as a synonym for open track for long and peaceful naps. Although if we look at the figures, we can find more relevant details than mere fillings to sleep. The western triumph. During 2025the Western has been a genre that has become an authentic props of thirteen programming. Classics such as ‘Rio Bravo’ have been among the most watched on TDT in certain days, reaching audiences of up to 376,000 viewers and 3.8% screen share, as happened last April 13. And on the way, surpassing in popularity strong programs of competitors such as ‘the Simpsons’ in Neox (which reached 2.7%). It is not an isolated case. ‘Rio Bravo’ was not a mirage. Films like ‘The IRA Valley‘,’Fury in the valley‘ either ‘Deep roots‘They have obtained Shares that exceed 5%, with peaks close to 5.6%, and between 400,000 and 465,000 spectators. On average, the Western maintains frequent audiences between 250,000 and 450,000 spectators and installments that range between 3.5% and 5.6%, confirming something very valuable: the public loyalty to this strip and gender. Western everywhere. Seeing how good they are going with the genre, thirteen has increased their programming of this type, almost becoming, from the time of desktop at night, into a thematic channel of the genre. They have double sessions between 14:40 and 6:40 p.m. In Access Prime Time, from 8:45 p.m. to 10:00 p.m., more modern and commercial westerns begin. Occasionally, there are even gender movies after 00:30 h. But what is thirteen? It is a TDT channel of the Spanish Episcopal Conference and is operated by Average apsethe same group as Radio Cope, Rock FM or Chain 100. Its programming is based on the dissemination of Catholic values and focuses on content for the whole family. However, it is not an especially buoyant business for the group: has accumulated losses exceeding 100 million euros since 2010. The reports indicated financial difficulties, with Returring indebtedness and losses Structural Is it a real success? These audiences do not compete with general television: the thirteen westerns stand out within the thematic TV, being leaders or seconds of the thematic channels, but Far from the great programs of your Stripwhich usually exceed 10% of Share. However, they are notable figures if we compare them with their usual competitors: Nova’s soap operas (such as ’emanet’ or ‘my secret is you’) or ‘the one that is coming’ in fiction factory, which are the ones that usually shine in these stripes. Not everything that is advertised is the most popular. A note that can help give a dimension of this success is that ‘nor that we were Shhh’, the successor program of ‘Save me’ in Ten He got audiences that did not reach 3% And they stagnated in their last weeks below 2% of Share. And yet They got a space in La1. It is normal, from that point of view, that thirteen is trying to replicate the success of his desktop westerns to all corners of his grill.

Spain has just changed the fiber optic rules after 25 years. The decision benefits a company: Telefónica

by

The National Markets and Competition Commission He has decided to completely free Telefónica of its obligation to share the fiber optic network with other operators. A measure that ends almost three decades of state supervision initiated after the privatization of 1999. Why is it important. Telefónica thus recovers the total autonomy about its infrastructure of 30.8 million houses covered. You can freely decide who your network shares, at what price and under what conditions, without prior regulatory supervision. The context. Since the privatization of Telefónica at the end of the last century, the State imposed the obligation to rent its network to competitors to promote competition. What began with Gigaadsl in 1999 evolved until NEBA in 2012forcing the operator to initially share 100% of its network, reduced to 25% since 2016. What has happened. The CNMC Council approved on July 29 eliminated these restrictions for two key reasons: The Masorange fusion has created a competitor that surpasses Telefónica in number of clients. The broadband market has greater competition with new independent wholesalers and more fiber deployments. In detail. The resolution will enter into force in February 2026, giving six months to the operators that NEBA use to renegotiate agreements or migrate customers to other networks. Telefónica will keep only The framework obligation of renting physical infrastructure such as arches and pipes. And now what. On the one hand, Telefónica will gain commercial agility by not needing prior approval of the CNMC for new offers or technical changes. On the other hand, its competitors will lose the advantage of knowing in advance the strategies of the operator, which until now had to pass the regulatory “replicability” filter. The big question. How will you use this new freedom to compete. The operator can now launch offers without notifying their rivals or waiting for regulatory approval, just when it must present their new strategy – that of The era with Murtra in command– Before ending 2025.

We have been talking about high speed between Lisbon and Madrid for years. Portugal is looking elsewhere: Galicia

by

Galicia and Portugal share cultural, economic ties and a intense very intense cars flow forced to circulate on one of the highways more dangerous from Spain. That last could change in a few years. Portugal has activated His administrative machinery to build the first high speed between Aveiro and Porto, a key piece of the Lisboa-Oporto railway corridor that looks beyond Portugal and aspires to link with Galicia. With the echoes of the debate of whether Lisbon, high speed must be prioritized with Madrid or Galicia, the public body infrastructure of Portugal (IP) is very light: Aspires to link Lisbon with Vigo and A Coruña to leave a population bag of 11 million people only three hours from the Portuguese capital. What happened? That Portugal has just given A key step For the implementation of the Lisbon-Porto high speed line, a railway corridor that will link the two main cities of the country and will continue north to the border with Galicia. A few days ago IP and Advance Norte- Gestão Da Ferrovia de High Speede signed A concession contract of the first high speed between Lisbon and Porto: 71 km between Porto and Oiãin the Aveiro district. What exactly agreed? What they signed is a concession and financing contract, which in turn clears the design, construction and maintenance of the Porto section to Oiã for 30 years. “When it is finished, it will allow the connection between Lisbon and Porto in an hour and 15 minutes, with an expected use of almost ten million passengers a year,” Clarify Carlo Fernandes, from IP. In addition to the 71 kilometers of line, the project will incorporate a station in Vila Nova de Gaia, a bridge over the Duero and an electrical substation in Strare. And what about investment? The signing of the agreement also served to present the financing agreement between Advo Norte and the European Investment Bank (BEI) for 875 million euros, part of the global loan of 3,000 million euros approved in 2024 by the BEI to support the new line. Vigo lighthouse It states that in the first phase the Next Generation funds will also contribute 447 million. “This is a true turning point,” Celebrate Nadia Calviñoformer Minister of Economy and current president of the BEI. And why is it important? Because those 71 km are the first step of a much more ambitious race, the first phase of the new Lisbon-Support line. In total that initial corridor will be extended 143 km Between the Porto-Campanhã and Soubo station, in Coimbra. The high -speed corridor between the two major cities of Portugal, Lisbon and Porto, is divided into several phases that extend to Oiã, from that town to the district of Coimbra and the latter to the Lisbon area. A few months ago, In MayInfrastructure of Portugal also guaranteed that its objective is that the works for the new line between Braga and Valença do Minho, already at the northern end of the country, touching the border with the south of Galicia, start in 2028 and that the infrastructure is completed shortly after, in 2032. But … how does Spain affect? How important is the future high -speed future line between Lisbon and Porto or plans to extend the infrastructure even further north of the country? Simple. Procedures such as that of a few days ago, which seems to have cleared the future of the Porto-Oiã section, gradually shaping the new railway axis that will link the Portuguese capital with the north of the country and, ultimately, will link with the Galician rail service. It is not theory. Although the project takes time on the table and over the last years has taken both steps forward and backwards, the high speed connection with Galicia is linked to the development of the Lisbon-Oporto corridor. It He has made clear Fernandes himself, vice president of IP: “We will get with the Lisbon-Porto-Vigo axis to place A Coruña and about 11 million inhabitants at a distance of three hours from Lisbon.” The objective is not only to connect the lusas (large and intermediate) cities but to extend through the Atlantic strip. Is it the only project? No. The Lisbon-Porto High Speed Line and its connection with Galicia has been on the table, but in the neighboring country they handle another key project: the corridor Between Lisbon and Madrid. What is a priority? Which one is most interested in Spain? And to Portugal? In the past both countries have signs that their answers to those questions do not always coincide. During the summit Hispanic-2004 The Spanish government promised to “boost high speed between Madrid and Lisbon by 2030”. On the section of Porto to Vigo, assured “Share with the Portuguese Executive the commitment of 2032”. For the Portuguese president, Luis Montenegro, things seem to be somewhat different. After the bilateral assembly, he wanted to “make clear” that his “priority” is the Galician connection and that Madrid is actually a “second priority.” Is it the first time that happens? At all. It is not the first time that dissonance is revealed. In 2020, with António Costa in the Portuguese Government, it was even clearer when after the XXXI Hispanic Summit the Minister of Cohesion Territory, Ana Abrunhosa, left black on white Your posture. “Our priority is not the connection between Madrid and Lisbon because from Madrid to Lisbon we go by plane. We already have connection. Our priority is the Lisbon Atlantic Axis, Porto and Vigo”, He stressed Abrunhosablunt. Galicia and Portugal share economic ties and an intense flow of vehicles, which converts the A-55 highway, into Vigo, into The great door for filmed traffic between both countries. The Lisbon-Madrid connection that would limit the three-hour trip is expected a priori by 2034.

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

by

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.

Bill Gates has been using a powerful tool for creativity and innovation for years: loneliness

by

Loneliness has Very bad reputation. As the neuroscientific nicole vignola assured In one of its conferencesthe negativity bias is very powerful when talking about it. As Remember From the European Institute of Positive Psychology, “loneliness is not being alone, it is the ability to be with no one.” However, loneliness intentional and well understoodIt is the Perfect culture broth To shape To the great ideas and as a tool to build the foundations of self -confidence and mental balance. Many of the great technological, scientific or artistic achievements have been possible because, at a given time, their drivers They have moved away from everything and everyone To concentrate on shaping your ideas. His brains only needed A little loneliness. When the urgent eclipse to the important At present there is more value to what The New York Times called “Hustle culture“, To have the agenda of the day to overflow with tasks, instead of the real luxury that is to keep it completely empty and allocate time to think in the really important. How are creative and innovative ideas to arise if We don’t even spend time thinking about them and why not, to wander? That superpower of emptying the agenda and allocating time to reflect is something Bill Gates learned from his friend and mentor Warren Buffet, as confessed in A joint interview. Science has demonstrated That letting your brain rest and not doing anything is like letting your brain release in an amusement park. In that context, loneliness is a great ally. As shown in the Netflix series ‘Bill Gates: Under the magnifying glass’Microsoft’s founding millionaire is taken every year a “week of reflection”, in which solitude is withdrawn to a refuge in nature to read, reflect and generate new ideas. According The published by The Wall Street JournalHence, initiatives such as Microsoft Internet Explorer browser emerged in 1995. It has not been the only one, such and as stood out Susan Cain in The New York Times, “Steve Wozniak achieved the work (to unite the components of the first Apple) – the hard work of creating something from nothing – did it alone. At the time of the morning, completely alone.” Some of the great masterpieces of literature or art have emerged from intentional isolation of its authors. Of take distance from the noisy world and let the brain stop receiving external stimuli that distract him from what really matters: generate new ideas. The science of success of being alone Scientific evidence confirms what the great geniuses of technology or art have already demonstrated. Even Seneca dedicated a good part of his Morales Epistles to Lucilio to the noble art of reflection in solitude and its benefits. According to a joint study Of the universities of Michigan and Harvard, highly intelligent people often experience greater vital satisfaction when they reduce their frequency of social interaction. “Participants with high intellectual coefficient expressed higher levels of satisfaction when their social contact was more sporadic.” This finding has been confirmed by parallel investigations from the University of Buffalo, which conclude that people who enjoy the solitude voluntarily They show high levels of creativity and self -reflection. Alone According to He counted to CNBC Joseph Jebelli, postdoctoral researcher at the University of Washington and author of the book ‘The Brain at Rest ‘spend time with oneself and let the brain Rest without stimuli nor external conditioning could be key in personal and professional development. The expert ensures that There is no perfect amount of loneliness And it depends on each person, but points out that the more values those moments of loneliness and self -reflection, the better it will be for your brain because more opportunities will have to wander and Connect unconnected ideas and abstract knowledge to generate a new one. Jebelli recommends starting in a simple way and intentionally searching for 10 minutes of loneliness per day in a quiet place “where they do not bother you and take advantage of that time to sit and breathe. This small step can help the brain to enter a state of relaxation and to start the activation process of the activation of the default neuronal network“ The neuroscientist not only recommends taking care of the moments of loneliness, but also being selective with the moments of socializationseeking that “it is a significant and quality activity. Many of us spend time with people with whom we should not because we feel forced.” According to Jebelli, this “toxic” socialization increases blood cortisol levels causing them to be harmful to mental and physical health. More and more people travel alone or They look for isolated retreats as a way to reconnect with themselves and reduce the social overestimulation, As documented The confidential. This phenomenon is perceived as an act of autolide and not negative isolation, and allows Strengthen self -esteem and provide people with psychological tools to improve the way they face day -to -day challenges and problems.

The solution to the drone problem was in an invention of 500 years

by

Although for a while to this part The drones It seems that they are associated To the war machinery of the different Conflicts on the planetthe truth is that its utility has always been ambicious much further of the contests. These devices could be the solution to many of the problems of the big cities, but they have several “buts”, and one in particular. It turns out that the solution has been able to be in a notebook for centuries. Leonardo and a “modern” dilemma. The genius Leonardo da Vincialthough limited by the technology of his time, he seems to have once again found validity five centuries later. Their notebooks, full of visionary schemes, included the Famous “Air Screw”a helical design conceived as a flying machine that, although it was never built or viable with the media of the Renaissance, already represented an early idea of propeller generating support. Now, a study from Johns Hopkins University, Available in Arxiv And still pending pairs, it points to this mechanism could solve one of the most serious problems of current drones: excessive noise. A contemporary problem. The drones, no doubt, have become a omnipresent tool: They serve For bailouts in The Himalayasfor Environmental experiments in Pacific Islands, to Military Missionsartistic or even recreational. However, society is beginning to perceive them as a growing source of noise pollution. A 2021 report I already noticed that the noise of the drones not only equals, but it is More annoying than traffic or conventional aviation. The reason is not only the sound intensity, but the quality of the frequencies that generate: acute, sinusoidal and persistent tones, which bounce on the ground and amplify its irritating effect. Parallel investigations They have explored metamorphic materials capable of absorbing until 94% of the noisebut the great challenge is still to rethink the propeller itself. Renaissance inspiration. This is where the researchers led By Suryansh Prakhar They look at Leonardo. That Air screwpossibly inspired by the beginning of Archimedes’ screwwas three -dimensional modeling by CAD and subjected to numerical simulations to evaluate their performance against conventional two -blade rotors. Although in its Original Conception It had to be driven by men running around an axis (which made it unfeasible in its time), its helical geometry was surprisingly promising. The modernized model, based on the design ELICO from the University of Maryland in 2020, he showed that the air screw was not only able to generate support, but did With acoustic advantages and energy efficiency. Science verdict. The results They indicated that, for the same lifting load, the air screw requires Less mechanical power and produce Less noise than a conventional propeller. Its largest contact with air allows you to turn more slowly, thus reducing turbulence and emitting smaller, less irritating and rapid dissipation sounds. In practical terms, the Leonardo design It would not exceed modern propellers in absolute thrust capacity or performance optimization, but it does offer a concrete way to solve the problem of noise in densely populated urban environments, where the social acceptance of drones is still limited. LESSONS OF THE PAST. He study It does not propose to immediately replace current rotors, but to point out that unconventional geometries, inspired by ideas such as Da Vinci, can open roads to drones most silent and sustainable. The paradox is eloquent: centuries of aerospace research had not seriously considered this helical form, and now science recognizes that a fifteenth century sketch It contains useful clues for 21st century engineering. In Prakhar’s wordsthe objective is to continue exploring traditional, experimental and biomimetic configurations to perfect aerodynamics and aeracoustics of drones. Ultimately, rather than demonstrating that Leonardo “invented modern drone”, the investigation Validate your talent to think radically differently, remembering on the path that technological progress does not always advance in a straight line and that sometimes the future needs the past to find answers.

OpenAI is already generating GDP size benefits from a small country. Follow light years of being profitable

by

Winning 12,000 million dollars a year seems somewhat prodigious for any company, but not when that company is called Openai. The evolution of income is being remarkablewithout a doubt, but both her and others – and here Anthropic is another good example – something serious happens to them: that they continue to spend more than they win. 12,000 million for OpenAi in 2025. As indicated In The Informationa new estimate that Openai’s “annualized” revenues will be 12,000 million dollars in 2025. The figure is a projection, but it is significant taking into account that in 2024 the estimated revenues were according to various sources of 3.7 billion dollars, although In Reuters They talked about the fact that they had actually reached 5.5 billion dollars. And 4,000 for Anthropic. The same media also recently indicated how the estimate in the case of one of its great rivals, Anthropic, has also risen and now It is 4,000 million dollars. Just two months ago that figure had already been checked and was 3,000 million, which means one thing: both are growing in number of subscribers. 700 million “Chatgpteros”. Another of the data to which the information article points out refers to the number of weekly active users. According to their data, 700 million people use chatgpt at some point in the week, which marks a unique milestone for the company. It is true that the vast majority of them are users of the free version, but that base is what allows part of those who use the service for free They end up pointing out to any of the chatgpt subscription plans. Income growth is being unusual in OpenAi and Anthropic, but both companies are spending absolute fortunes to end up being profitable. Source: Reddit. It will win 12,000 million, how much will it spend? In Reuters indicate that the internal estimates of the company also point to higher expenses. According to those projections, OpenAI will spend 8,000 million dollars, but that figure is dentra on direct operational expenses. There are many more associated expenses – investments, infrastructure, other financial obligations – and that makes OpenAi not profitable for now. We do not have estimated spending data for Anthropic, but it has an identical problem: Spend more than you earn. Spectacular, but. Although this growth in income is certainly extraordinary, it must be taken into account that to achieve this, these companies carry “Burning money” for years. The investment rounds that Anthropic and especially OpenAi have captured have allowed them to have a lot of room for maneuver to lose huge amounts of money without that at the moment that worries too much. And they will continue to spend as possess. Especially in the case of Openai, which thanks to SoftBank support It has great plans that will make it necessary to spend true fortunes. They have done it to Buy the Jony Ive design study for 6,500 million dollars, but above all they will do it with the project Stargatewhich still seems like very difficult to complete. But no profitability until 2029. Those responsible for OpenAi do not seem too worried, and we knew what the company’s financial road map was known weeks. They will continue losing money until 2029when supposedly – all is a free estimate, not a promise – will earn 100,000 million dollars. It will be then when the company will begin to be really profitable, but again, All this is a promise (or maybe a hope). It could not perfectly be fulfilled … and even ending up falling short.
