he exchanged ballet for a fortune of 1.3 billion

by

At just 29 years old, Brazilian Luana Lopes Lara has become the youngest self-made billionaire on the planet, with an estimated net worth of $1.3 billion. She is not the youngest millionaire, but she is the one who has achieved it on her own merits, and not as fruit of an inheritance. The rapid rise of her Kalshi betting platform has seen her co-founder surpass figures like Taylor Swift and the entrepreneur Lucy Guo in the ranking of the youngest millionaires in the world. Younger and younger millionaires. According to ForbesLuana Lopes Lara is the youngest self-made billionaire in the world with an estimated net worth of $1.3 billion. This fortune comes from his direct participation in the company he co-founded with Tarek Mansour, at a time when the valuation of the betting platform that rivals Polymarket has reached $11 billion. In this new map of great female fortunes, Luana has displaced Lucy Guo30-year-old co-founder of Scale AI, who had previously taken the title from Taylor Swift who surpassed the billion barrier at the age of 34 thanks to her tour The Eras Tour. Extreme discipline and turn towards technology. Luana Lopes Lara was born in the state of Santa Catarina, Brazil, into a family closely linked to science: her mother is a mathematics teacher and her father, an electrical engineer. Since she was little, she combined intensive study with classical dance, until she reached the prestigious Bolshoi Theater School in Brazil, where she combined academic studies with a strong discipline in dance. according to what he said People. After finishing high school, she worked for nine months as a professional dancer in Austria before “hanging up her shoes” and betting on her other great passion: computing. She moved to the United States to enroll at the Massachusetts Institute of Technology (MIT), where she was able to do internships at financial firms such as Bridgewater Associates and Citadel, experiences that brought her closer to the world of markets and quantitative risk management. At MIT he met his current partner Tarek Mansour, also a computer science student. Kalshi’s big bet. The idea for Kalshi began to take shape in 2018, when Luana and Tarek did a summer internship at the investor Five Rings Capital. There they began to give shape to their idea of ​​creating a platform that allows operating directly on the probability of certain real-world events occurring, from elections and macroeconomic phenomena to sports results or pop culture topics. Convinced that there was room for a regulated prediction market, they submitted their project to Y Combinator, Sam Altman’s accelerator, and were accepted in 2019. As and how do they count On its website, in November 2020, Kalshi obtained the license from the Futures Trading Commission of US Commodities (CFTC) to operate as a Designated Contract Market (DCM), which allowed its products to be classified as event contracts and separated from unregulated betting, unlike competitors like Polymarketsanctioned with 1.4 million dollars for operating without federal registration. That regulatory difference gave Kalshi a strategic advantage over its main rival. The figure of Luana: leadership, resilience and vision. Beyond the figures obtained by his startup, Lopes Lara’s story has become a story of personal resilience and young leadership in the technology and financial sector. His time in professional ballet, marked by extreme discipline and training that left no room for error. “We saw that most stock trading occurs when people have a vision of the future and then try to find a way to translate it into the markets,” the millionaire businesswoman told Forbes. transform that bet on future events in a million-dollar business has been what has turned Lopes Lara into one of the new stars of Silicon Valley.

McDonald’s has not learned from Coca-Cola and has presented a Christmas advertisement made with AI. The reactions have been even worse

by

Everything indicates that the negative reaction to use of AI in Coca-Cola Christmas ad It has set a precedent… but it has not discouraged large corporations. MacDonald’s has made its own greeting with synthetic images and the reaction has been so overwhelmingly negative that the company has decided to remove the spot from social networks. Once again, issues such as creativity, aesthetics, profitability over ethics and, above all, what majority reactions they are generating are put on the table. What has happened? McDonald’s Netherlands has withdrawn its Christmas campaign generated entirely with artificial intelligence after facing a avalanche of criticism on social networks (and after being forced to disconnect comments on their profiles). The advertisement, ironically titled “It’s the most terrible time of the year”, is a perversion of the classic Christmas carols, and showed disasters with a festive atmosphere: traffic jams in which Santa Claus is involved, rebellious fir trees, unpalatable family members… the whole pack of suffering of these dates, to remind us that at least we have McDonald’s left. The problem. As happened with Coca-Cola, the problem is twofold. Aesthetically, the result is spooky.: Disturbing physics, expressionless faces, slapstick humor taken to the extreme because of that strange elastic and surreal violence of the AI. But above all, it makes viewers and critics wonder about the ethical legitimacy of this type of operationswhich completely dispense with human capital to produce more and faster. We are facing the first steps of an experimentone that corporations will put into full gear as soon as public rejection eases. Who has done it. The burger brand had entrusted production to the Californian duo MAMA (Mark Potoka and Matt Starr Spice), together with the AI ​​division The Gardening.club of the studio The Sweetshop. In a post that has since been deleted, the directors defended their work: The announcement required “seven intense weeks” of work, investing in it “more hours than in traditional production. Their central argument: “AI didn’t do it. We did it.” The controversy with Coca-Cola. The McDonald’s disaster represents the year’s second major Christmas controversy involving AI-generated advertising. A month ago Coca-Cola ignited a similar debate by launching its remake of the iconic 1995 ‘Holidays Are Coming’ spot, this time produced using generative artificial intelligence and starring animals… after the poor reception that a spot with the same concept but starring people had in 2024. The Atlanta multinational hired three specialized studios (Secret Level, Silverside AI and Wild Card), but the reaction from the public and critics was devastating. A reflection on that rejection, in reference to the 2024 ad with non-existent humans: Tim Halloran, who worked for a decade in Coca-Cola’s brand management division, stated that the campaign constituted “a violation of the brand promise” of Coca-Cola since, “for years, the core of that brand has been the idea of ​​authenticity.” Toys R Us too. Ahead of Coca-Cola’s first spot, in June 2024, Toys R Us debuted “the first commercial ad created with Sora,” OpenAI’s text-to-video tool. The one-minute spot narrated the origins of the company through its founder Charles Lazarus, combining images of the boy who would end up creating the store with the mascot Geoffrey the Giraffe in completely synthetic sequences. The industry reaction was almost unanimouswith people like Joe Russo stating in X that the ad It was “shit”. The impact on brand perception was measured Marketing-Interactivedocumenting negative reactions from 53.4% ​​of the spot’s viewers. The problem of authenticity. Behind the rejection of these ads there is a deeper problem than mere poor technical execution. In December 2024, NielsenIQ published research that revealed how viewers cognitively processed AI-generated advertising, and the result was not very promising: consumers consistently rated these contents as “annoying,” “boring,” and “confusing,” even when the technical quality was high. Neeraj Arora, professor at the University of Wisconsin-Madison, explained why the rejection is particularly acute in the Christmas context, with special attention to the Coca-Cola spot: “The holidays are a time of connection, of community, of coming together with family, and that’s a big part of what the holidays are about. But when you introduce AI into the mix, it doesn’t fit: it doesn’t fit with the festive moment, but also, to a certain degree, it doesn’t fit with Coca-Cola and what the brand stands for.” Christmas, traditionally a space of emotional authenticity, collides head-on with the synthetic nature of AI. Controversial results. The cases of McDonald’s and Coca-Cola illustrate a contradictory reality: the speed of production and cost savings that AI promises do not necessarily compensate for the loss of emotional connection with audiences. The consumers are developing rapidly the ability to identify synthetic content, and their immediate reaction is rejection.

the flu marks 15-year highs in Catalonia and the worst is still ahead

by

Spain is experiencing a great flu epidemic right now, with a large number of infections expected to arrive to its maximum peak at Christmas itself. The problem is that at the moment the ascending phase does not stop increasing, causing the flu curve to have an insane growth, being able to affirm that we are facing a historic epidemic and that the truth reminds us a lot of the wave we experienced during covid. Although above all it has targeted some communities. A localized anomaly. As the Ministry of Health points out, this epidemic does not stop increasing in our country on a national scale, but above all it has hit the most populated communities in our entire geography. Today, flu cases are estimated in an incident of 170 cases per 100,000 inhabitants nationwide. But some autonomous communities are seeing a greater impact with historic rates, as is the case, for example, in Catalonia or Madrid. Something that strains health services and forces measures to be taken, such as need to wear a mask in certain locations. An unprecedented epidemic. This is the case of Catalonia, where the graphs already point to a flu epidemic that is the worst in the last 15 years, with a graph that can undoubtedly be scary due to how sharp its escalation is. In this way, this clashes between the local situation in the autonomous community and the national paradigm where the ceiling has not yet been reached. The data published by the Catalan epidemiological service confirms a statistical anomaly in the week of December 1 to 7, since they suggest that The barrier of 300 diagnoses has been broken for every 100,000 inhabitants in primary care, with a weekly increase of more than 100%. It is something so intense that some experts they point because until the end of the year very intense days are expected in Primary Care and ‘wild’ guards in the Emergency Room. But some of them already point out that “and“This flu curve is insane.” The same in Madrid. Another quite worrying situation where cases reach 275 per 100,000 inhabitants, making it much higher than what has been seen in previous seasons, which also marks an unprecedented fact and which already forces vaccination campaigns to be intensified. ‘Zoom out’ from Spain. If one looks up from the Catalan and Madrid map and looks at the consolidated data from the Ministry of Health and the ISCIII for all of Spainthe film changes genre. It is not a disaster movie, but a thriller that is picking up pace. At the national level, this epidemic has been characterized by a significant advance in the epidemic wave, since at the beginning of December there was already an infection rate of 70-80 cases per 100,000 inhabitants. But despite this fact, national surveillance reports continue to increase to an overall ‘low’ or ‘moderate’ intensity. The measures that have been taken. At the national level, the autonomous communities managed to reach an almost historic agreement: recommending the use of masks in health centers. But Catalonia, with a historic epidemic, has had to take other measures such as is wearing the mask mandatory (something that also Murcia has approved) in health centers. Although, it is ruled out in other areas such as public transport. Primary care. One of the most affected by this epidemic, which has numbers of such magnitude from counting the cases at the primary care level. This contrasts with the data used by national surveillance organizations, which weight hospitalizations, ICU admissions and deaths much more. Something that is not happening critically, waiting for the peak of the epidemic to arrive.

An “invisible” Russian submarine has set off alarms in the Arctic. Europe’s response: Atlantic Bastion

by

The launching of the Khabarovskthe new and ultra-quiet Russian submarine capable of deploying nuclear torpedoes Poseidonhas reactivated a fear that had been latent for decades in cities like London: the possibility that the naval balance of the Atlantic is once again tilting in favor of Moscow. The response from the United Kingdom has been forceful, and it is called Atlantic Bastion. Submarine warfare. Although the public image of the Russian threat usually revolves around research vessels like Yantarsuspected of mapping and potentially manipulating underwater cables and pipes, European specialists know that what is truly disturbing lies much further down. Russia has spent decades reducing the acoustic signature of its submarines to levels that they border on invisibilitycombining new propulsion systems, composite coatings and virtually undetectable cooling pumps. In this environment, where silence is power, a ghost submarine with nuclear capacity alters not only the sea routes, but the very heart of the strategic infrastructures that connect Europe with the world. UK reinvents itself. Faced with the resurgent threat from Khabarovskthe Royal Navy has launched what they have called as Atlantic Bastiona plan designed to restore British strategic advantage in its own and allied waters. Its origin is not new and it we have counted before: the United Kingdom has been monitoring the Greenland-Iceland-United Kingdom gap (GIUK gap) since before the creation of NATO, and the Second World War already demonstrated that controlling that maritime corridor was essential to prevent enemy forces from slipping into the North Atlantic. But what used to be destroyers and acoustic sweeps is becoming a hybrid framework that combines Type 26 frigates equipped with new generation sonar, aircraft P-8 Poseidon capable of patrolling thousands of kilometers and, above all, swarms of underwater drones equipped with artificial intelligence. According to the Ministry of Defensethis architecture aims to detect, classify and follow any enemy submarine that tries to penetrate British or Irish waters, and to do so constantly, autonomously and with an unprecedented range. The algorithms arrive. The core of the project will be Atlantic Neta distributed network of autonomous underwater gliders equipped with acoustic sensors and guided by artificial intelligence systems capable of recognize sound signatures with a level of precision that until a few years ago was little less than the preserve of science fiction. Unlike the SOSUS of the Cold War, based on gigantic fixed hydrophones placed on the seabed, the new generation will be mobile, expandable and adaptable to the routes and behaviors of increasingly soundproof submarines. The ultimate ambition is to deploy hundreds of cheap, persistent units that together create aa surveillance mesh much harder to evade. The metaphor is revealing: if finding a silent submarine is like searching for a needle in an oceanic haystack, modern technology makes it possible to exponentially multiply the number of searching hands. Khabarovk The technological challenge of hunting shadows. However, even with this technological revolution, experts warn that detecting new Russian submarines will continue to be an extremely complex undertaking. Since the 1980s, Moscow has drastically reduced lacoustic emissions of its fleet, which requires combining passive and active sensors and complex configurations such as bistatic sonar, where one vessel emits a pulse and another collects the echo. These techniques require coordination, multiple platforms, and significant sensor density, something that Atlantic Bastionaims to provide but it is still far from being deployed on a full scale. The arrival of the Type 26 frigates, designed to be the flagship of British anti-submarine warfare, is fundamental to this purpose, as is the cooperation with Norway and other allies that are also strengthening their capabilities in the North Atlantic. The Russian Bastion Puzzle. Even if Atlantic Bastion managed to limit the presence of Russian attack submarines in the Atlantic, there is one dimension that no Western system can solve: Russian strategic submarines already they don’t need to abandon its own bastion in the Arctic to threaten Europe or the United States. Its intercontinental ballistic missiles can hit targets thousands of kilometers without moving from the Barents Sea or the White Sea, protected by layers of defenses and favorable geographical conditions. There they play a hiding place lethal where the West cannot penetrate without significantly escalating the conflict. The paradox is clear: the United Kingdom can reinforce its waters and monitor every meter of the GIUK gapbut it cannot deny the Russian nuclear capacity deployed in its natural refuge, a reality that frames the entire British effort within a logic of containment rather than domination. An underwater chess. If you want, Atlantic Bastion ultimately represents the recognition that underwater competition has returned with a vengeance, now fueled for digital capabilitiesdistributed sensors and autonomous platforms that transform the nature of ocean surveillance. The North Atlantic once again becomes a stage silent maneuvers where Russia and the United Kingdom measure their technological resistance in an environment reminiscent of the Cold War, but with algorithms and autonomy as new weapons. A career that is not decided by great battles, but by the ability to listen better, process faster and anticipate invisible movements. In this theater of shadows, the advantage is not whoever shoots the most, but rather whoever is able to detect first (already happens in Ukraine). Thus, Atlantic Bastion aspires to return that capacity to the British, although the contest that is opening now does not look like it will be brief nor simple: In the depths of the Atlantic, the prelude to the next era of strategic rivalry between Russia and the West is underway.

Torrejón de Ardoz promised them happiness as the epicenter of the Madrid festivals. Until he started canceling them

by

Torrejón de Ardoz does not seem willing to become the epicenter of the Madrid festivals. Although City Councils usually boast of their ability to attract concerts, fairs and other mass events, a few days ago the Consistory of the Corredor del Henares did exactly the opposite: published a statement to announce the cancellation of “all macrofestivals that were made in the city.” From their extensive list only one will be saved, Elrow Town. The rest will be forced to find a new location next year. What has happened? Que Torrejón de Ardoz has announced the “cancellation” of three music festivals: Brava Madrid, Madrid Salvaje and Torrejón Summer Fest. The reason? The Consistory alleges basically two reasons. The first, that he wants to “minimize the inconvenience to the neighbors.” The second, that in the opinion of the municipal government, the leisure offer for the inhabitants of the town is already well covered with the Magical Christmass and the patron saint and popular festivals. “They offer an excellent offer of free leisure and a sufficient attraction, such as large events, to promote the Torrejón Ciudad de Moda brand,” he says. Is everything cancelled? No. They fall at least Brava Madrid, Wild Madrid and Torrejón Summer Festbut not the Elrow Townwhich will be celebrated on a holiday (May 1) during daylight hours. From the Torrejón City Council they argue that the festival does not cost the municipal coffers money and represents an “important” source of income for the town. In addition, residents will have the right to purchase tickets starting in April with a 50% discount. Click on the image to go to the tweet. What does it mean for Torrejón? A priori and how recognize the City Council itself, the fairgrounds will be left without events for most of the spring-autumn season of 2026. At the moment there is nothing scheduled for March, April, July, August and September. In June and October there will also be no appointments, except for the celebration of Popular and Patron Saint Festivals, respectively. The strong month will be May, with elrow Town, Tributos, Locos X80 and Urban. The City Council assures that an effort will be made to reduce the acoustic impact, which would even include orienting the stage towards the Polígono de Las Monjas, in such a way that the sound is not directed towards the homes. During elrow Town, the installation of acoustic screens is planned to protect the buildings. Why is it important? Because of the context. Madrid Salvaje, Brava Madrid and elrow Town had not been in Torrejón de Ardoz for long. What’s more, the three festivals they relocated there this year after having to leave IFEMA. In the Torrejonero area they found a large, close space, well connected to Madrid and with green areas. Its great potential led to some saw to the town of Corredor del Henares as the potential new “epicenter” of the Madrid festivals, a not unreasonable possibility after the turn from IFEMA. A few months ago the IFEMA consortium confirmed their decision not to hold outdoor festivals at least in 2025 and focus on indoor ones. The measure came at a special time, with those responsible for the fair institute betting on the organization of the Spanish F-1 Prize, which will be held in September 2026. in spring The World public In fact, IFEMA’s step back from the open-air festivals sought to appease the residents’ spirits ahead of the Formula 1 event and the noise that the cars may cause. Perfect, right? It doesn’t seem like it. Although the festival organizers stood out At the time, the advantages of moving to Torrejón de Ardoz had, in practice things seem to have been different. At least for its inhabitants. In the statement in which it confirms the cancellation of “all macro-festivals” (except elrow Town), the City Council insists that the objective is to “minimize inconvenience to neighbors”, a maxim that goes beyond the musical calendar. “The City Council, listening to the feelings of many Torrejoneros, is going to reduce and celebrate fewer events, concerts and parties, and will focus all its efforts on taking better care of and keeping the city cleaner,” the statement continues. Neither Torrejón nor the neighborhoods close to IFEMA are the first to have seen how difficult it can be to combine the residential use of an area and the celebration of mass shows. Probably the most publicized case is that of the complaints of surrounding neighbors of the Bernabéu, which even led to heavy fines. In Torrejón, an extra element was also added that has little or nothing to do with noise: several festivals They were tarnished by their ties to a pro-Israel fund in the midst of the Gaza war.

We criticize the EU a lot with its obsession with regulating Big Tech. There are at least two examples that justify this obsession

by

The Digital Markets Act (DMA) and the AI Law They are two of the great exponents of something that the European Union is highly criticized for: his regulatory obsession. It is true that these regulations restrict companies and can slow down European innovation – this has happened with AI – but these worrying side effects are accompanied by others that are much more welcome. Especially because this regulation has made the world a little more interoperable. There are two great examples of this. First example: USB-C. The adoption of the USB-C connector as the mandatory Being able to charge mobile devices and other hardware products is undoubtedly positive for users. Although the standard has its own problemsits use as a universal connector has avoided the use of proprietary connectors that made interoperability difficult and caused greater problems for the environment in the form of electronic waste. Second example: Universal AirDrop. We have also recently seen how Google offered support on the Pixel 10 to be able to transfer data to an iPhone or iPad thanks to AirDrop support in QuickShare. That support will be extended to other Android phones soon, and that improves interoperability between both platforms. From now on it will be much easier to transfer photos directly from mobile to mobile (be it iPhone or Android) wirelessly, and there we have to thank the European Unionwhich forced Apple to modify the way AirDrop works to comply with the DMA. And there is still more. These efforts to improve interoperability will soon be even more rewarded. Google and Apple have announced their collaboration in making portability between different platforms much easier. Thus, changing from an Android mobile to an iPhone or vice versa it’s going to be easier thanks to the efforts that both companies are making. Why have they made that decision? Again, due to the “regulatory obsession” of the EU. The EU sticks out its chest. Euroregulators in fact celebrated this decision by Google and Apple these days, and affirm that the renewed interoperability “is an example of how the Digital Markets Act (DMA) offers benefits to both users and developers.” That same regulation was what allowed iOS 26 to add support to transfer an eSIM to and from an Android mobile, for example. The EU against (almost) everyone. The EU’s regulatory obsession may often be criticized, but the truth is that it is the great reference when it comes to confronting the unlimited ambition of Big Tech. It has done so in the past with the RGPD or with the DSA and the DMAand now with the AI ​​Law. In all of them the ultimate goal is normally reasonable, although it often happens that the regulation ends up being exaggerated or, as with AI, comes too soon. The last chapter of obsession. European regulators suspect that Google is using content from news publishers and other creators to train their generative AI without permission and without offering compensation. These practices may constitute an abuse of Google’s dominant position in the market, which would negatively affect both competition and content publishers themselves. This research also affects “AI Overviews,” which extract and summarize information from other websites, potentially reducing traffic to those original sources. Brussels Effect. The application of these regulations in a market like the European one causes the so-called “Brussels effect”. For large technology companies such as Apple or Google, it is more efficient and profitable to adopt a single standard for all their products worldwide than to design specific versions only for the European market. Thus, this obsession not only benefits us European citizens (when it does), but also ends up becoming the de facto standard worldwide, as has happened with the USB-C connector. This regulation ends up becoming a powerful engine of global change. It is not perfect by any means, and we are seeing it with the AI ​​Law or the cookie nightmare, but even in those cases the EU seems to have realized and is trying to change things. The challenge of the AI ​​Law. If the DMA pursues interoperability, the AI ​​Law seeks transparency and compensation to prevent these monopolies from consolidating in this era of generative AI. The investigation into Google is not only a defense of copyright, but a preventive measure against competition. Meanwhile, the US and China seem turn a blind eye and we have even seen how the leaders of big technology companies They ask that copyright laws not be applied arguing the famous “fair use” of those contents that have little de jusot, at least for content providers. In Xataka | All the big AIs have ignored copyright laws. The amazing thing is that there are still no consequences

turn off cell phones when night comes

by

On the Ukrainian front, the battle for the networks It has been escalating in importance over the months. Ukraine has been clear about this since a date to remember its troops took place. It happened with Operation Spiderwebwhen the Ukrainian Security Service smuggled small FPVs near five Russian air bases in trucks. The drones were launched and controlled via the Russian telephone system. The result: the destruction of at least ten strategic bombers. That was recorded in Moscow, and now they are using it. The transformation of the telephone. The war in Ukraine has turned something as everyday as mobile phones into a decisive system combat, revealing a profound change in the nature of modern conflict: civilian networks have become de facto military infrastructures, and every signal, every SIM, every tower and every data packet can be an offensive tool or a weak point. Tension has escalated to such a point that Russia, unable to fully control how Ukraine exploits its cellular network to direct precision drones over long distances, has begun to cut off mobile service at night in entire regions. The situation illustrates a disturbing paradox: without mobile phones the aerial threat is limited, but with them civil life, emergencies, commerce and governance itself are kept functioning. For the first time, a great power is openly assuming a social and economic cost in exchange for stopping the advance of the connected war. The tactical revolution. The ability of Ukrainian drones to use Russian infrastructure as if it were their own has been one of the most striking developments in the conflict. Cheap devices, such as DJI cellular donglesturn an FPV drone into a platform capable of operating hundreds or even thousands of kilometers from the pilot, as long as there is 4G coverage. As we said, that same technology allowed the famous Operation Spiderweb. The pattern now repeats itself: Iranian Shahed modified with 4G modems that transmit video in real time, Ukrainian FP-1/2 drones that avoid defenses thanks to cellular links, or Russian Molniya that act as aerial nurses to transport FPV above electronic interference waists. The drone no longer depends on the range of its antenna: it depends on the telephone infrastructure, turning each tower into an involuntary military node. The Russian response. Faced with this new front, Russia has tried close the gaps without disrupting the entire digital ecosystem… but intermediate solutions are failing. His first step was block for 24 hours any SIM that had been roaming, a measure designed to detect Russian cards clandestinely sent to Ukraine. Then it expanded the blocking to inactive cards for 72 hoursa sign of growing fear that thousands of Russian SIMs are involved in attacks without their users even knowing. Finally, in several border regions the most extreme measure– Cut off mobile data at night, when attacks typically occur. This dynamic not only harms to the civilian populationbut also illustrates the loss of control of a State that sees its commercial infrastructure turn against it with disconcerting ease. The historical precedent. The West already knew about the problem of telephony as a weapon, although never on this scale. In Iraq, a simple Nokia 105 could detonate explosive devices improvised with a reliability and range that would have seemed like science fiction in the nineties. To counteract this, jamming systems were deployed. as Warlockcapable of blocking signals in the surroundings of military convoys and columns. Today, that same logic reappears with more complexity: any drone that uses a cellular network can be neutralized by blocking the signal, but doing so involves simultaneously blinding ambulances, firefighters, security forces and millions of users. What was once a tactical dilemma has become a strategic one: what can be blocked without leaving an entire country in operational silence? An even more difficult future. The next technological leap makes this equation even more fragile. Both Russia and Ukraine already operate drones equipped with Starlink receivers or other direct satellite connectivity services. This marks the end of the absolute dominance of the electromagnetic territory: a drone that receives orders from orbit is immune to cell towers and to classical terrestrial interference patterns. As direct-to-satellite terminals for civilian use proliferate, it will be nearly impossible to distinguish between benign communications and command signals for hostile drones. In that scenario, an operator located on another continent could direct an attack with surgical precision without depending on any network national security or expose oneself to foreseeable countermeasures. The battlefield ceases to be geographical and becomes a global digital space, where physical borders matter less than the availability of orbital constellations. Control the spectrum. If you also want, the case of mobile phone in Ukraine illustrates how modern warfare has infiltrated all layers of civilian life, blurring the lines between public infrastructure and military capability. The Russian decision to turn off the network at night is not only a symptom of technological vulnerability, but also a advance of the type of conflicts that are coming: wars where each smart device is an antenna, each user a possible vector and each network a battlefield. In this new paradigm, the question no longer points to how to defend a country, but rather to how to defend an infrastructure designed to connect millions of people without turn it into a weapon involuntary.

There are dozens of influencers obsessed with helping us choose the perfect can of tuna. The problem is that what they say doesn’t make much sense.

by

There is a fine line that connects volcanic eruptions, oil combustion, and waste incineration with our kitchens: mercury. A mercury that is produced in dozens of activities (mostly human), which ends up deposited in the waters, transformed into methylmercury by millions of microorganisms, stored in fish and, finally, in our stomach. It was only a matter of time before it became the huge food scandal it is today. Methylmercury also reaches social networks. The problem is so big that there is no shortage of experts and influencers that defend messages such as choosing cans of “tuna” over cans of “light tuna.” The music is that of institutions such as the European Food Safety Authority (EFSA) that recommends avoiding large fish; The lyrics hide many problems. At the end of the day, the viral message mixes correct intuitions, with more than debatable scientific evidence (it uses, to begin with, commercial classifications that do not have direct Spanish correspondence). This is not the first time that an idea that sounds good ends up giving us headaches. And why is that a problem? Because, like it or not, fish is a centerpiece of many diets. Not only for its protein contribution, but as a priority source of certain fats that are very difficult to replace by any other means (e.g. omega-3). The thing is, with all that, comes methylmercury. And exposure to methylmercury is a tricky thing: it can harm brain development and be toxic to the nervous system. In fact, it can cause symptoms such as tremors, memory loss, and cognitive dysfunctions. The most vulnerable groups are pregnant women, nursing mothers, babies and young children. Do all fish have the same amount of mercury? No, it doesn’t. According to the Spanish Agency for Food Safety and Nutritionthere are four really dangerous species: the swordfish or emperor, the bluefin tuna (Thunnus thynnus), the shark (dogfish, mako shark, dogfish, dogfish and blue shark) and pike. These are problematic in women who are pregnant or planning to be pregnant, nursing mothers and children under 10 years of age. In fact, AESAN recommends directly avoid its consumption. The rest of the species are not problematic for the effects of mercury: they are safe and healthy. And the AESAN recommends between three and four servings a week even in the at-risk population. And aren’t there more differences according to levels? That is, are there only dangerous and non-dangerous species? No no. It is true that each species contains a different amount of mercury. In fact, each copy has different levels. That’s where the problem comes from: we need simple ‘rules’ to help us deal with uncertainty. On a practical level, according to the available studies, we can only define species with low mercury content as those on this list: Pollock, Anchovy, Herring, Cod, Bacaladilla, Cockle, Mackerel, Squid, Shrimp, Crab, Cane, Coquina, Carp, Squid, Clam, Choco/Cuttlefish, Lobster, Coquina, Sea bream, Sprat, Prawn, Horse mackerel, Lobster, Prawn, European sole, Dab, Sea bass, Mussel, Merlan, Hake, Razor clam, Oyster, Pomfret, Flounder, Squid, Octopus, Shrimp, Atlantic salmon, Pacific salmon, Sardine, Sardinella, Sardinopa, Plaice, and Trout. Everything else has medium levels and making distinctions between them is impossible on a practical level. So it doesn’t make sense to follow these types of recommendations?

The rest of us mortals only hope to be healthy after the Lottery draw. Spain wins “ultra-rich.” He UBS report points out that in Spain there are already 32 people with assets exceeding 1,000 million dollars. This represents a net increase of eight new ultra-rich in the last year since the same 2024 report recorded 27 assets over one billion in Spain. UBS calculates that, together, these 32 great fortunes reach 213.1 billion dollars, equivalent to about 182.6 billion euros, as calculated Forbes. …and they are getting richer. This equity volume represents a growth of 21.5% compared to the previous year, an increase that UBS links to the good performance of some of the main businessmen in the country and to the greatest concentration of assets in the hands of a few families. According to these same sources, Spanish billionaires have added around 11.6 billion dollars (about 9.94 billion euros) to the national wealth in the last year, reinforcing the weight of this small group in the economy. Six out of every ten euros in the hands of Amancio Ortega.
