Vivo X300 Ultra vs Xiaomi 17 Ultra, we put two of the best phones of 2026 in photography face to face

by

If you value the photographic section of a mobile phone above the rest, this year we are seeing very good proposals. Therefore, now that we have a greater variety of phones, we are going to take the opportunity to put two of the most notable of this year face to face: the Xiaomi 17 Ultra and Vivo X300 Ultra. Vivo X300 Ultra (1 TB) – Photography kit The price could vary. We earn commission from these links The price could vary. We earn commission from these links The differences between the Vivo X300 Ultra and the Xiaomi 17 Ultra Camera configurations Before getting into the matter, it is advisable that we take into account which sensors come in each of the mobile phones. Furthermore, it may not be the biggest claim, but we will also mention the front sensor in each case. Vivo X300 Ultra 50 MP front camera, f/2.45. Rear camera module: 200 MP main sensor, f/1.85, OIS. 200 MP telephoto, f/2.67, OIS. 50 MP wide angle, f/2.0, FOV 123.4º, OIS. Xiaomi 17 Ultra 50 MP front camera, f/2.2. Rear camera module: 50 MP main sensor, f/1.7, OIS. 200 MP telephoto, f/2.4 – 3.0, 3.2x to 4.3x, OIS. 50 MP wide angle, f/2.2. main sensor Perhaps the most attractive thing about this section is the difference in megapixels in both main sensors. The Vivo X300 Ultra has 200 MP and the Xiaomi 17 Ultra with 50 MP. Is one better than the other? Well the truth is that no. To give you an idea, having more megapixels is relevant especially when we want to crop an image, since what we want is to be able to enlarge it without losing too much detail. But it is not the only thing we should focus on, because megapixels do not really equal image quality. The Xiaomi 17 Ultra has a one-inch sensor, being the largest on the current mobile market. This means it can capture much more light, offer truer colors and a much more natural blur effect. In this way, the Vivo It is also especially relevant to stop at the focal aperturebecause it is different in both cases. The Vivo mobile phone offers an f/1.85 aperture while the Xiaomi phone has an f/1.67 aperture. The lower the number, the more light enters through the lens, which makes for better photos in low-light conditions. Telephoto lens In the telephoto sensor there are many points to discuss. First of all, both brands are betting on 200 MP sensors, which, as we have already mentioned, serves above all to not lose so much detail when enlarging an image to crop it. In the focal aperture of this sensor we do find differences and some other peculiarities. The aperture of the Vivo is f/2.67 while that of the Xiaomi is f/2.4 – 3.0. And… what does this mean? The Xiaomi 17 Ultra can vary its focal aperture between f/2.4 and f/3.0, which allows it to adapt to different light conditions automatically. We must also point out something important and that is that the Xiaomi 17 Ultra allows you to vary between 75 and 100 mm through zoom, which allows you to change between 3.2x and 4.3x. This previously had an impact on the image quality, but the mobile processing works very well, so it is practically not so noticeable. In addition, we also have a 200 mm, which is a sensor cutout, which approaches optical quality. ultra wide angle camera In both cases we find two 50 MP ultra-wide-angle sensors, so they offer the same detail. What does vary is the focal aperture: the Vivo’s (f/2.0) is more open than the Xiaomi’s (f/2.2), so more light will enter and it can perform better in difficult conditions. The attractive thing about the Xiaomi 17 Ultra is that it offers a 115º field of viewwhich means you can capture more information in a single photo. However, our recommendation is that to take close-up photos, we move away a little and take them at 100 mm and crop the image. The result is much better. The accessories Both phones have their respective photographic kits; However, they are very different. Xiaomi is betting on an accessory that, in general terms, is a case with a battery and physical controls to take photographs. There are two with different prices, with the most expensive being the one with the most controls. On the other hand, the Vivo X300 Ultra comes with a much more attractive photographic kit, since in this comparison it is the only one that has a teleconverter. In this case, it is 400 millimeters and, although it works well for photographing at long distances, we loved the quality it offers in portraits. Prices Price is a key factor when choosing a mobile phone and here we are going to find a big difference. The Xiaomi 17 Ultra (512 GB) is on sale right now for a price of 1,249 euroswithout the photographic kit. On the other hand, the Vivo X300 Ultra (1 TB) can currently only be purchased with the photographic kit, so the price shoots up to 2,399 euros. To understand the price difference between both phonesthe Xiaomi is located by 1,249 euros without kit. If we wanted the photographic kit, we would have to pay additionally 280 euros for Photography Kit Pro or 116 euros for the Photography Kit. The first has more buttons and a larger battery to function as a powerbank. On the other hand, the Vivo X300 Ultra comes with the photography kit included in the price of 2,399 euros. That is, in addition to the mobile phone we find a Vivo ZEISS Gen 2 Ultra teleconverter with an equivalent focal length of 400 mm, a grip with an integrated battery to function as a powerbank and an adapter ring for a tripod. In summary: In any case, we are talking about two mobile phones with very powerful photographic sections. It is difficult to assess which is better and which … Read more

Two companies have teamed up to put their own space garbage truck into orbit

by

As the space race advancesso does the generation of debris, which includes everything from fragments of parts to discarded phases of rockets or complete ships that lost their orbit. This space debris accumulates, generating more and more risks. It is clear that it must be managed in some way, but all the hypotheses proposed have been left in the air. Now, however, two private companies have proposed the development of a kind of space garbage truck, which can lead the process to become operational and repeatable. Just like that truck that passes by your window every morning, they also hope to achieve frequency and efficiency with their waste removal service. The truck and the garbage can. The two companies that have proposed this service are the American Portal Space System and the Australian Paladin Space. The first has developed Starbust, a maneuverable and resupply ship that works like a garbage truck. The operator or garbage dump would be Paladin’s contribution, a payload called Triton. This is responsible for both obtaining images of space debris and classifying and collecting the debris. While the experimental proposals that have been made so far would collect one or very few objects, this combo would collect many more in a single mission. A regular service. Both companies have assured that they are working at a good pace, so they hope to make a first launch at the end of 2026. If all goes well, they would begin doing more regular missions from 2027. It would be a repeatable and well-organized service, which would try to keep at bay the space debris debris that, logically, will continue to be generated. More and more space junk. It is currently estimated that there are more than 130 million pieces of space debris in low Earth orbit. It is a figure that may possibly increase, due to something known as Kessler syndrome. The term refers to a kind of domino effect whereby, if a piece of space debris hits a satellite, for example, even more debris will be generated, which will continue to collide with each other, increasing in number more and more rapidly. The risks. Space debris is dangerous for many reasons, all of them largely related to impacts. To begin with, they can affect artificial objects that are also in orbit, such as satellites. Furthermore, if the impact occurs on manned facilities, such as the International Space Station, or spacecraft, the lives of the astronauts would be put at risk. And we cannot leave aside the risk posed by space debris when it deorbits and returns to Earth. Normally, most of the pieces disintegrate when crossing the atmosphere and do not even reach the Earth’s surface. However, debris may remain capable of causing material or personal damage. In fact, in 2022 a study was published which pointed out that, in the subsequent 10 years, the risk of a piece of space debris falling on a human being is 10%. It is worth launching as many cosmic garbage trucks into space as possible. We will avoid many problems if they work as expected.

Microsoft put the head of its AI department in charge of Xbox. Now it’s dismantling all of Xbox’s AI

by

Asha Sharman is the new CEO of Xbox and has arrived with a mission: to blow up Xbox. At least, that is what he is proposing in the first three months of his mandate in which he took the reins of the company in one of the worst moments in its history, with a diffuse identity and with the responsibility of filling the shoes of a Phil Spencer who had been with the company for 40 years. The most curious thing is that Sharma came from presiding over CoreAI, one of Microsoft’s most important AI divisions, and is doing the opposite of what many of us expected. Dismantle AI from within. Distrust. The Xbox brand is not going through its best moment. Since the disastrous E3 in 2013 where the Xbox boss said that if someone didn’t want an always-connected console (Xbox One) they could stick with their old Xbox 360, things have gone downhill. That someone was a Don Mattrick who was replaced by Phil Spencer and with whom things began to change. Game Pass, studio purchases to feed the ecosystem and strategy changes such as launching games on PC and PlayStation. The accounts seemed to come out in services, but not in hardware or games. After all this time, Phil retired and a totally different profile arrived: that of Asha Sharman. The directive I wasn’t a gamer like Phil, he also had no gaming experience. He came from leading CoreAI, a Microsoft team focused on accelerating the development of AI software for internal and external customers to build and run AI applications and agents. Out with the AI. When it was announced that she would be in charge of replacing Phil, in the midst of the ‘Microslop’ meme, many of us feared the worst for the division. Even one of the fathers of Xbox He pointed out that Sharma was going to bury Xbox. However, through Twitter, the CEO has just launched a release quite interesting: “Xbox needs to move faster, deepen our connection to the community, and address friction for both players and developers.” It would seem like just another message, that typical ‘CEO language’ that so many managers use, but it has gone one step further by committing to something interesting: “Today we promoted leaders who helped build Xbox while bringing in new voices to help us move forward. This balance is important as we get the business back on track. As part of this change, we will begin removing features that do not align with our intentions and plans for the future. “We will begin scaling back Copilot on mobile devices and will stop development of Copilot on consoles.” CoreAI Avalanche. This implies a shift in the strategy of a Microsoft that, like others like Meta, they had become an AI company. They have pushed Copilot to its limits, putting it on capon even on televisions thanks to commercial agreements or by renaming its office suite so that, now, its most important services were Copilot and, therefore, artificial intelligence. These statements, therefore, represent an interesting change, as interesting as seeing who are those who now manage Xbox. Sharma talks about “new voices” and what contrasts with this plan to dismantle Copilot in some of the products is that many of them come from… CoreAI. As they point our colleagues from 3DJuegos, The Verge raises a list of four very important members of that AI division who, now, come to Xbox to work with Sharma when defining the future strategy and the new machine: Project Helix. Return to fan. It is not Sharma’s only turn in this short period at the helm of Xbox. From the “everything is an Xbox” campaign, tremendously controversial because if everything is an Xbox, nothing is, we move on to a “we are xbox“, a return to those origins in which an Xbox is an Xbox, and that’s it. Well, also the PC, which is receiving its ‘Xbox mode‘ to improve the video game experience. There is rumors that they are considering returning to exclusives (PC and Xbox) abandoning launches on platforms such as PlayStation 5 and They have lowered the price of Game Pass Ultimatethat it was shot a few months ago. Of course, although they lowered the price, they also left ‘Call of Duty’ out of the subscription, so that reduction is misleading. I want to believe. Now, you have to be careful with all this. Although they are already taking some actions (that “reduction” of Game Pass or stopping the development of Copilot on Xbox), the return to exclusives and the roots of Xbox are issues that remain to be seen. Until they start taking more forceful action, we won’t be able to assess how far Sharma has gone to do things differently. Furthermore, and it is not to look for spins on Sharma’s statements, the board has pointed out that they stop Copilot on consoles. And that word, “consoles,” is very important because we don’t know what Project Helix will be. Your new machine definitely cannot be classified as a console because the machine itself Microsoft is positioning it as a PCone in which the crisis of components will impact strongly both in availability and price and it remains to be seen if they miss that opportunity to bring AI to the living rooms. But well, it is evident that the new CEO has arrived at Xbox wanting to wage war and we can think “ok, but above it is someone with more power: Satya Nadella.” And yes, Nadella has been one of the great drivers of converting Microsoft into an AI company, but just yesterday the company’s CEO sent a powerful message: clean Windows of so much garbage to win back the fans. Only time will tell, but it is evident that Microsoft’s image is not going through its best moment.

Someone has put everything they need in a survival flash drive.

by

The massive arrival of the Internet and connected devices have implemented a half-truth in our daily lives: that there will always be connectivity. And it doesn’t have to be. I discovered it the hard way on April 28, 2025, the day of the blackout: Without cash, something as common as eating out and paying with a card became an impossible mission and involuntary fasting. With information, more of the same: the usual Wikipedia or Google Maps are of little use without the Internet (in fact, download the original is always a good idea). Someone has wondered what would be left on your computer when the Internet goes down and to address that uncomfortable but legitimate question, they have launched a “survival kit” that fits on a USB flash drive. You insert it into your PC, it boots directly from there and it comes with everything. Yes, also an AI assistant. The project. shelters is an open source project created by Spanish Spanish dev Javier Prieto. What it essentially offers is a lightweight variant of Ubuntu preconfigured with a selection of tools designed to work completely offline. The heart of the project is an installation script: you prepare a USB with the base system, you connect it to the Internet once to run that script and you no longer need the Internet. Why is it important. The refugiOS proposal solves a real problem that is often overlooked: the vulnerability of depending on the Internet and its infrastructure. In the event of a serious emergency, such as my blackout, but also natural disasters or conflicts, what the servers offer will be inaccessible. And it will be the time when you need them most. Having that data physically stored without the need for external and foreign infrastructure can make a difference. Emergencies aside, the project evidently also satisfies from a privacy point of view. Everything you consult in refugiOS stays on your machine. There are no servers that record your activity, conversations or routes or share them with the AI. In a context where data and its analysis are increasingly the order of the day, having tools that work without filtering data to the outside provide value beyond being useful in the event of a possible apocalypse. And it offers one more extra: total portability. What does shelter bring?. The available content is grouped into five blocks: Offline library and encyclopedias: Wikipedia, WikiMed and WikiHow thanks to Kiwix. Maps and GPS navigation with offline search and routes using Organic Maps. Artificial intelligence. An AI assistant run locally available in three power levels depending on the RAM of your computer: from the basic Phi-4-mini for any PC with 4 GB of RAM to Qwen3-14B that requires 16GB to Qwen3-8B, which requires 8GB. Encrypted file vault (LUKS standard) to protect sensitive files. General tools like LibreOffice, VLC or Syncthing. There are three AI models depending on the hardware of your computer. GitHub Context. There are a few digital resilience projects, including Kiwix, which has been distributing Wikipedia offline to areas without internet for years; but what refugiOS is about combining several of these options into an all-in-one, ready-to-use system, which is also accessible to someone who doesn’t have too much technical knowledge. And it also comes at the best time. On the one hand, because there has been a real boom in small and efficient language models (something that a couple of years ago was unthinkable) and on the other, because of the current situation: conflicts, the flooding of AI to each and every one of the Internet sectors or the shift of the American technological monopoly of the West towards a more invasive policy. refugiOS takes advantage of that technological window and opportunity to add a layer of comprehensive utility. In detail. The project has deliberately conservative design decisions in that it ensures that the system boots and runs smoothly on basic and/or veteran computers (with 4GB of RAM), being easy to maintain and distribute. In fact, the documentation explains how to copy it to pass it on to your people. Of course, its status is still quite incipient: it is functional, but with room for improvement in the interface, documentation and language coverage. However, its roadmap is ambitious, with thousands of public domain books through Project Gutenberg or support for shortwave radio receivers.

The war machine that the US destroyed, Iran has put it back on its feet

by

During the Vietnam War, American pilots bombed for days a network of tunnels near Cu Chi convinced that they had completely rendered it useless. When the troops advanced on the ground, they discovered that not only was it still operational, but the combatants they had reappeared from hidden exits a few meters from their positions. The scene left a brutal lesson: destroying from the air does not always mean eliminating what is below. A start of war that changes everything. The first hours of the conflict in Iran set the tone of everything that would come later: an intensity of fire rarely seen, with hundreds of missiles and almost a thousand drones launched in just two days, forcing the defensive systems to operate at the limit from the first moment. That volume not only showed the scale of the Iranian arsenal, but also the type of war that was being waged, one in which saturation was almost as important as precision. From that starting point, the expectation was clear for all the actors: if that rhythm was sustained, the key was not going to be who hit the hardest, because that actor had a name from the beginning, but who last longer. The illusion of total destruction. Because the United States and Israel responded in the first 48 hours of war with a massive campaign of bombings that sought to disable the Iranian military infrastructure, attacking thousands of targets and sealing access to underground bases to leave the launchers trapped. For weeks, the official message It was forceful.: The missile program had been devastated and the country’s response capacity was practically nullified. However, even at that time doubts arose from within the US apparatus itself, which warned that a significant part of these systems had not been destroyed, but simply blocked or temporarily inaccessible. Iranian efforts underway at a missile base in Tabriz on April 10 The mountains as a shield and strategy. It we count at the time. The real differentiating element was not in the missiles, but in where they were stored. Iran has spent decades building a network of underground facilities in mountainous environments, many of them excavated in granitic rock capable of resisting extremely powerful attacks. These “missile cities” not only store weapons, but also integrate complete logistics systemswith tunnels, launch points and escape routes designed to minimize exposure. It is an architecture designed for survive the first blowassume damage and keep the operational core intact, in a logic that prioritizes resilience over invulnerability. A loader over debris blocking an entrance to a missile base near Khomeyn, April 10 Dig, reactivate and launch again. Satellite images now have confirmed that, as soon as a ceasefire window opened, heavy machinery went into action to remove debris and reopen accesses blocked by bombings. As? The Telegraph said Through satellite survey that dozens of excavators, trucks and engineering equipment were deployed at key points to clear sealed entrances and regain access to buried launchers. Again, what is relevant here is not just that it is being done, but the speed: in a matter of days (and even in just 48 hours in some cases) those facilities have become operational again, suggesting that much of the military capacity was not destroyed, but simply paused. Designed to resist. All of this, furthermore, fits with a very specific doctrine: assume that the enemy will have air superiority and design the system to survive it. Unlike a conventional war, where losing control of the air usually implies the progressive destruction of infrastructure, here the logic is different and focuses on protect assets critical underground, absorb the first attack and recover capacity combat as soon as possible. This approach turns conflict into a race of attrition, where each cycle of attack and reconstruction erodes both the attacker and the defender. The real problem. If you like, the direct consequence of this dynamic is that the apparent initial success of Washington (and Israel) has lost weight in the face of the recovery capacity Iranian. Because, although the attacks have been massive and technically effective, the speed with which Tehran is restoring its bases raises an uncomfortable scene for their adversaries: every pause, negotiation or ceasefire in the fighting becomes an opportunity to rearm again or, literally, dust off the bunkers In that context, the question stops being whether an infrastructure can be destroyed and becomes how many times it can function again before the other side is left behind. without resources or without political margin to continue.

They have put the 21 most popular AI chatbots to perform differential diagnosis. They fail more than a fair shotgun

by

‘House‘It’s a series that I love. I don’t care about the intrastories in the slightest, but the process of differential diagnosis – despite all the movie stuff – drives me crazy. This ability to rule out diseases that could explain the same symptoms to arrive at the most probable diagnosis seems like witchcraft to me. Well: they have put the 21 Most Popular AI Chatbots to make that differential diagnosis and the result is clear. It fails more than a fairground shotgun. In short. He Mass General Brigham It is not an ‘anyone’. It is a non-profit network of American doctors and hospitals, including two of the most prestigious medical teaching institutions in the country. From January to December 2025, a group of researchers from the institution they put 21 AI chatbots such as Claude 4.5 Opus, DeepSeek, Gemini 3.0 Pro, GPT-5 or Grok 4 to evaluate dozens of clinical cases with the aim of establishing their level of success in an early diagnosis. The information is extremely basic, but it is also what professionals have when making this differential diagnosis and the ultimate intention is to evaluate the clinical reasoning capacity of the latest generation language models to see if they can be a clinical ally. The answer is no. While models optimized for reasoning achieved much higher scores than simpler ones like Gemini 1.5 Flash, the bottom line is that LLMs are still limited for this task. The exam. Each of the models was given 29 clinical cases that represent more than 16,200 responses in total. The result is that these newer versions of the most powerful chatbots they couldn’t produce an adequate differential diagnosis in about 80% of cases when they only had basic information about the patient. The problem is that age, sex and symptoms is very vague information, yes, but it is one that human professionals who have to make this differential diagnosis ‘play’ with for the first time. Little by little, as they do other tests and obtain more information, they refine the result, but it is that first ‘discard’ treatment that often makes the difference. “We want to help separate the hype from the reality of these tools as they are applied to healthcare” another movie. And, precisely, as the LLM They were given more data, the performance and results were more robust. When the chatbot has more and more information such as physical analysis data, laboratory results and diagnostic images, things change and AI reaches the final diagnosis in more than 90% of cases. But of course, to reach that stage they must have almost all the clinical data, which further shows the gap with impotence when performing an initial filtering. Don’t trust Google ChatGPT. The researchers are clear that “these models are very good at identifying a final diagnosis when the data is complete, but they have difficulties at the beginning of an open case,” which leads them to emphasize that they should not be trusted at home. The AI ​​industry is pushing your product in the medical circuit, but the study points out that “despite continuous improvements, commercial LLMs are not ready for clinical implementation without supervision.” They state that a human is needed in the operation and “very close supervision” to be able to scale the use of an LLM in the healthcare field. And there they are always talking about professional use, but more and more cases are seen of people who previously treated themselves by trusting Google and who Now they do it trusting what ChatGPT tells them. In the study they emphasize that “hallucinations remain” in these latest generation models, also showing concerns about the safety and integrity of patients. About El Salvador. In any case, it is evident that, in the end, Medical AI is another helper, a tooland here what has been tested is a “common” chatbot that knows everything, but is not specialized in anything. In medicine, as in other industries, the use of AI can help with tasks such as eliminating possibilities or organizing thousands of data, but a chatbot is not yet a good companion in this differential diagnosis because it simply cannot be trusted. Those who are going to have to trust AI for any type of treatment are Salvadorans. El Salvador has been a pioneer country when it comes to adopting new technologies, and the president, Nayib Bukele, has just embarked on another experiment: $500 million to leave healthcare in the hands of Gemini. The population will have access to the app Dr.SV who will work as a family doctor. As detailed in The Countrythis AI will know the symptoms and will assign calls with doctors who will make the diagnosis. The AI ​​will monitor for consultations and chronic diseases and the goal is for it to take care of cancer patients in the future. According to Bukele, they are creating the best health system in the world, something curious considering that they laid off more than 7,700 health system employees during 2025. For the sake of Salvadorans, let’s hope that This new experiment does not end like Bitcoin City. In Xataka | Privacy is dying since ChatGPT arrived. Now our obsession is for AI to know us as best as possible

projections have just put on the table the worst El Niño in 140 years

by

It often feels like we are erasing the meaning of the word ‘historical’ by using it so much. And yet, here I am: about to say that seasonal prediction models show an “unprecedented” convergence in the same direction: an extremely strong El Niño before the end of 2026. If what the models say is confirmed, we could be facing the most powerful El Niño in at least 140 years. So yes, ‘historic’ is the appropriate word. But, first of all, let’s review what ENSO is. They are the acronym in English of El Niño-Southern Oscillation and they refer to a cyclical (although very irregular) climate phenomenon that has great effects on the global climate. Huge, in fact. If we exclude the stations, it is the most important source of annual climate variability from all over the planet. During the warm phase (that is, during El Niño), the absence of strong trade winds that cool the surface of the equatorial Pacific causes the temperature of that area of ​​the ocean to skyrocket. It is this, through different atmospheric teleconnectionswhich disrupts all the weather systems in the world. The effects are varied and change depending on the region (“drier conditions than normal in certain parts of the world; while in others it causes more precipitation. Some countries have to deal with major droughts and others with torrential rains”, says AEMET); but when we talk about temperatures there is no doubt: El Niño is synonymous with heat. Although, of course, that is in a normal ENSO. If we talk about the strongest ENSO event in a century and a half, everything skyrockets. The most likely conclusions tell us about a wild redistribution of heat globally, a more than likely temperature record for 2027 and a string of profound alterations in rainfall and hurricane patterns. And why do we think it will be like this? Fundamentally, because the convergence of the different models is a very strong indication. Not only is it that more than half of the probabilistic scenarios of the European model they project anomalies greater than +2.5 degrees in the equatorial Pacific, is that Zeke Hausfather (adding 433 members from 11 models) reaches the same conclusions. And what exactly is the news? Obviously, the news is not that El Niño is coming. We have already talked about that: The news is the strength (aggressiveness, even) with which it now appears in our projections. Or not even that. Because no one is very clear what an event of this type means in a climate context like the current one (it would arrive after three years above the 1.5 of the Paris Agreement). And that is a problem. “Problem”? It is also the most appropriate word. We must not forget that the super El Niño of 97-98, one of the strongest ENSOs in recent years, caused numerous consequences that lasted for years: the estimates say which caused damage to global economic growth of around 5.7 trillion dollars. If this event is greater than the one in ’97, the question is whether the improvements we have made since then are enough to contain the blow or not. The answer, I’m afraid, we will have in a few months. Image | Xataka In Xataka | “It is so extreme that it is difficult to believe”: El Niño forecasts depict an event of unprecedented intensity.

There are people obsessed with magnesium as a supplement when the best way is to put it directly into your diet

by

We live in the era of biological optimization, where The strange thing without a doubt is not taking dietary supplements from the supermarket such as magnesium, collagen, calcium, various vitamins… Magnesium in particular is sold as an almost magical way of sleep betterreduce anxiety and recover muscle. But the truth is that we are forgetting the most important thing: We have all this in food. The reminder. With so many food supplements (which often do not come cheap), sometimes we forget that we have these nutrients in the supermarket in different presentations. This is something in which Doctor Federica AmatiChief Nutritionist at ZOE Science & Nutrition, has put its finger on the sore spot of the supplement industry: For the vast majority of the population, there are plenty of pills and no food. Why magnesium matters. There is an obsession with taking this mineral, and the reality is that it makes sense because its functions are critical for our body to function correctly. Its fundamental role in many metabolic reactions of the body makes it essential for human survival, since without magnesium we would literally be extinct. And it is no wonder, because beyond being used to prevent cramps, it has important functions in energy production, DNA synthesis, metabolic control such as glucose levels, and also structural function by allowing bone to develop. Given its importance, the consumer logic seems simple: “If it’s so important, the more you take, the better”. But this is where science has to put the brakes on because a large amount does not always equal better performance. The best foods. One of the positions that we can have on the table right now is that magnesium supplements (and even others) are not necessary, unless it is known that there is a deficit. All this because it has a big problem: they are isolated. The problem with supplements is that they are isolated. NIH Office of Dietary Supplements (ODS) emphasizes that the food matrix It is irreplaceable. When you get magnesium from an almond or spinach, you’re not just ingesting the mineral, you’re getting fiber, phytochemicals, and other micronutrients that work together and that no pill can fully replicate. The daily doses. The official recommendations today indicate that the minimum levels of magnesium They are not unattainablesince for adult men between 400 and 420 mg per day are needed, while for women between 310 to 320 mg per day is sufficient. Low figures mean that they cannot be easily achieved with food by adjusting the shopping list without going to the pharmacy. Where can it be found. If the goal is to reach 400 mg daily, the strategy is not to look for supplemented foods, but to go back to the basics. In this case, science points because the food where we have the greatest amount of magnesium are seeds and nuts, where we find almonds, cashews and especially pumpkin and chia seeds. But in addition, it should also be noted that green leafy vegetables such as spinach or chard have chlorophyll in their composition, which also acts as a highly coveted magnesium reserve. All this without forgetting legumes and whole grains. Who needs supplements. Logically, they have a site, but it is by no means a universal recommendation for everyone who may have their requirements met with the diet. According to the ODS, there are different groups of people who may require this supplementation (under medical supervision). These are the following: Gastrointestinal disease such as celiac disease where nutrient absorption is compromised. Type 2 diabetes, since its pathophysiology causes a decrease in magnesium. Chronic alcohol consumption. Elderly people where absorption is naturally decreased. In these specific cases, the evidence indicates that supplementation can help improve parameters such as sleep quality or anxiety, but because they have an absorption problem.

Shakira wants to put 300,000 people in a place that does not convince the Government at all

by

Live Nation and Shakira have now officially presented Macondo Park, a 40-hectare temporary venue at the Iberdrola Music in Villaverde designed for close the tour ‘Women no longer cry’ with a nine-concert residency in Madrid in September. The problem: the Government delegate in Madrid has been warning for years that the space does not meet security conditions for massive events and has formally asked the City Council not to authorize them. Stadiums make money. What Shakira and Live Nation have presented is not exactly a concert: it is a temporary infrastructure designed ad hoc by the international study BIGknown for projects such as the Danish pavilion at the Shanghai Expo or the expansion of the National Museum of Qatar. According to data from the organization, the so-called Shakira Stadium will occupy four hectares within the Iberdrola Music space, with capacity for 50,000 people per night: 26,688 seats in the stands, 25,000 standing and around 3,000 in the VIP area. Macondism. Macondo Park will be deployed around the stadium, which takes its name from the fictional town created by Gabriel García Márquez in ‘One Hundred Years of Solitude’: 40 hectares active for twelve hours each concert day. The cultural program, baptized ‘Es latina’, includes gastronomy, workshops, exhibitions and sales of Latin American crafts, all selected by Shakira herself. There will also be a specific area for children called Macondito, designed (according to the organization) with the participation of the artist’s children, Milan and Sasha. The goal, according to Live Nation, is to “demonstrate what it means to be Latino” and project that cultural imaginary in Europe. Minitour without moving. Some pertinent figures: nine performances in Madrid, scheduled for September 18, 19, 20, 25, 26 and 27, to which have been added October 2, 3 and 4 due to the very high demand and how quickly the pre-sale sold out. The entire project expects more than 300,000 attendees throughout the residency. Ticket prices range between 73.50 and 181.50 euros, with VIP packages exceeding 1,000. And it will take 69 days to build the complete structure of this spectacular theme park around the artist. Problems in Villaverde. This great plan collides with a somewhat complicated background. Iberdrola Music is the same space that has hosted the Mad Cool festival for years. It was also the scene of the Harry Styles concert in 2023, where organizational failures led to monumental traffic jams and part of the audience ended up walking along the M-45. In the letter he wrote to the City CouncilGovernment delegate Francisco Martín recalls that he already warned about the venue in July 2023 on the occasion of the Reggaeton Beach Festival. According to Martín, in an institutional meeting held in 2024 it was found that there continued to be “relevant deficiencies in terms of accessibility, mobility and organization of entry and exit flows, incompatible with the celebration of large events in safe conditions.” The administrator of the Mad Cool festival even faced a request for a two-year prison sentence from the Prosecutor’s Office for violations related to noise pollution. It’s not a festival. Martín also differentiates between the festival model, where the public enters and leaves in stages for hours, and the “fan phenomenon”: a massive concert where 50,000 people try to leave the venue in a very narrow time frame. It is this second scenario that, in his opinion, Iberdrola Music is not prepared to absorb. Crossing of accusations. As it could not be otherwise, this open letter was followed by an exchange of accusations with little or nothing to do with music. Borja Carabante, Urban Planning delegate of the City Council, accused Martin of “trying to boycott, harm and harm the city.” Mayor José Luis Almeida pointed in the same direction: he described it as “extraordinary” that Shakira chose Madrid as the culmination of her tour and even hinted that up to ten dates could be held. Mariano de Paco, Minister of Culture of the Community of Madrid, defined it as “great news.” The preceding Adele. Promoter Pino Sagliocco, president of Live Nation, avoided entering the political fray. He defended that the mobility plan “is already done” and endorsed by engineers, and insisted that Iberdrola Music is “an experienced and well-conditioned space.” He compared Shakira’s plan to Adele’s precedentwho established his residence in a park in Munich, comparable in size to this Macondo. The center of the debate. There is slaps for pre-sale ticketsbut municipal authorization has not been granted, and the Government Delegation has made it clear that it will go “as far as necessary” to ensure that the venue offers guarantees. For now, there is silence from both sides of the Administration. The conclusion of all this is that the debate is not led by Shakira, but by Madrid’s real capacity to manage massive events outside the urban center, with access infrastructure that several reports consider insufficient. After 17 countries, Shakira’s tour culminates in the only place on the planet where organizing a live show means invoking a perfect storm.

NASA has put a Spaniard in charge of the project for its future lunar base: Carlos García-Galán from Malaga

by

Dressed in a jacket, light blue shirt and gold tie, Carlos García-Galán He did not occupy another chair at the NASA conference held in Washington. Escorted by the administrator Jared Isaacman and other top-level officials, the engineer from Malaga spoke before the press in the middle of the presentation of the agency’s new lunar turn. His presence at that time placed him at the forefront of a roadmap that redefines NASA’s priorities on the Moon. The context of that scene helps understand its relevance. Hours before,Isaacman had presented a roadmap that changes the focus of the agency. It is no longer just about returning to the Moon, but about establishing a sustained presence on its surface. The proposal involves deploying in three phases the initial elements of a permanent lunar base, with stable infrastructure and a logic that is more industrial than experimental. The man from Malaga who now pilots the Moon Base program This change of course also redefines the role of those who must execute it. In this context appears García-Galán, whose official position within NASA is “executive program” at the lunar base. This is a high-level management position, responsible for coordinate and guide program development, not an operational role on the ground. His role will be to lead the project from the agency structure, not to direct a facility on the lunar surface. García-Galán, remember, is not a newcomer, but an engineer who has developed his career within NASA and has been assuming responsibilities for years to get to this point. His presence in the announcement is linked to that trajectory, which now places him in one of the great bets of the US space agency at this stage. His career within NASA helps to understand why he has come this far. Before this appointment, García-Galán, according to LinkedInheld the position of “deputy manager” of the Gateway program, until now a relevant piece in the agency’s lunar architecture. With more than 27 years of experience In manned space flights, he has worked on the design, integration and operation of complex systems, participating in programs such as the International Space Station and the Orion spacecraft. His experience at Gateway also helps explain this appointment. In that program, García-Galán was involved in integration and management tasks within an environment with multiple partners and components. The new approach towards a lunar base requires precisely this ability to order diverse pieces, from missions to infrastructure, something that fits with the profile that has been developed within the agency in recent years. The program that he will now supervise is divided into several phases with a common objective: establishing a sustained presence on the lunar surface. NASA proposes a sequence of missions that will go deploying infrastructurefrom mobility and energy systems to communications networks and habitats. The idea is to advance progressively towards a base capable of sustaining longer-term human stays.
