Sending electricity without cables seemed to the future. Darpa has done it again, and the test has gone better than expected

What are 800 watts? More or less what a microwave consumes running at medium power. And 8.6 kilometers? It is an approximate distance between the stations of Atocha and Chamartínin Madrid. It is actually somewhat lower, but it serves to get an idea. That is the scale of Darpa’s last experiment: a system that managed to transmit real energy with a laser, in a straight line, without cables and with a receiver that turns the light into usable electricity. It may seem little, but it is not. The important thing was not the amount, but the test. And it worked. What exactly Darpa has done. The United States Advanced Defense Research Projects (Darpa) has successfully completed The first phase of a program called Power, designed to explore new ways of transmitting long distance energy. In their most recent test, carried out in New Mexico, they managed to send a laser beam that delivered about 800 watts for 30 seconds to a receiver located 8.6 kilometers. The figure is important because it exceeds the previous records: until now, the best documented result was 230 watts at 1.7 kilometers. Although the agency has not revealed how much power it was originally issued, it is known that the system was able to maintain energy flow for periods even longer than those officially reported. According to those responsible for the project, it was not about demonstrating efficiency, but viability. The essential thing was to check if it was possible to build a functional system in a short time. And they did it in just three months, from the initial design to the final execution. The receiver was developed by Technc Technologies and uses commercial solar cells already available in the market. The objective was not to optimize performance to the maximum, but to prove that this technology can be launched with accessible components and without complex manufacturing processes. How this technology works. The idea behind the experiment is simple to understand, although technically complex: send energy through the air with a beam of light, and that when it arrives it can be used as electricity. The DARPA system is based on an infrared laser that points directly to a receiver composed of a conical mirror and solar cells. The mirror captures the ray and redirects it towards the panels, which convert light into electrical energy. Part of the equipment used during the test The interesting thing is that no exotic components or photovoltaic cells were used to measure, as in many laboratories. Commercial cells were used, ready to use, which reinforces the idea that this technology can be viable out of paper. As we say, the performance, for now, was not the priority. Receiver efficiency is around 20 %. The Power Receiver Array Demo system achieved a new record by transmitting laser energy with more power and greater scope than ever During the test, diffractive optics were also used, an unusual resource in this type of transmissions, and an integrated cooling system was implemented directly in the optical parts, manufactured with additive printing techniques. None of these innovations was scheduled at the beginning. They were solutions that arose on the march, as they faced the challenges of the experiment. Why do it with laser and not with radio waves. Transmitting long distance energy is not a new idea. For decades it has been investigated how to do it with radio or microwave waves, but these technologies have physical limitations that include their effectiveness. As IEEE points outto work, they need large antennas and systems of Beamforminga technique that allows the signal to be concentrated in one direction. The longer the distance, the greater the issuer must be, and the more difficult it is to focus the beam with precision. Compared to radio waves, the laser can focus much better: a narrow beam can be created almost without dispersion, at least in ideal conditions, According to Eric YeatmanVice President of the College of Science and Engineering of the University of Glasgow. Of course, not everything is advantages. The lasers also disperse with fog, clouds or dust. In adverse atmospheric conditions, microwaves remain more reliable. But for certain applications, especially if we talk about aerial networks or transmissions in clear environments, the laser is difficult to match. For the Power project leader in Darpa, Paul Jaffe, if it does not work with optics, it will not work in any way. What does this advance mean (and what is not). Darpa’s experiment did not solve all the challenges of wireless energy transmission. Efficiency remains low, the system is not yet prepared to operate in adverse conditions, and the transmitted power, although notable, is far from what a commercial infrastructure would need. But that was not important. The important thing was to demonstrate that technology can work outside the laboratory, with accessible components and in realistic terms.

I’ve been sleeping badly for years, so I’ve tried “sleep headphones.” They haven’t been what I expected

I’ve been sleeping for years regulate. The classic culprits are discarded: I don’t take late or copiously, I don’t drink alcohol, I don’t take caffeine, I do sports, No mobile abuse just before going to bed… Simply I find it hard to fall asleep and sometimes wake up at several times during the night. So I wanted to whose car more and more manufacturers are climbed. In my case I have tried the Anker Soundcore Sleep A20. Let’s see how. What they are and what they promise Sleep A20 are wireless headphones designed exclusively for sleep. The first thing for what they attract attention: they are dwarves. The second: They are very light. The third: its profile is very low, they do not stand out from the ear. The closed box. Image: Xataka. Image: Xataka. Image: Xataka. They also come with several silicone and “wings” tips to adjust it, something especially important in some vermin that we are going to take sleeping for hours. The important thing is that they are not just headphones: Its application includes several environmental sounds, sleep monitoring and specific functions for the night. They can work in two modes: Bluetooth mode to reproduce any sound from our mobile. Sleep mode with soured sounds in the headphones. The experiment The first night was adaptation. I had never slept with a headset in my life. In addition, I usually sleep sideways. It seemed unlikely that a headset did not bother me. Minipunto for these, because I immediately forgot that I was wearing them. The flat design and the soft, gummy, flexible material, made it barely noticed additional pressure. Zero problem. They stand out practically anything. Image: Xataka. Image: Xataka. Then there was the issue of listening. Put to try, I let the application surprise me with its own proposals, which they call “brain waves with the” created specifically to help us fall asleep. We can choose whether listening to them only for a while, only until we stay asleep or all night. I tried the three: Only for a while: It gives what it promises. If we mark 45 minutes, at 45 minutes it will stop ringing. Only until we stay asleep: The same, detecting the moment we fall. All night: What a bad time. The sound made me wake up a couple of times, something disoriented by him. Perhaps it is a personal issue and there are people who have a reparative dream with the headphones sounding throughout the night. It is not my case and I advise to set the timer in a generous way to ensure that the shutdown will occur. The Yay and the Nay There are four elements that work really well here: Exceptional comfort. They have never been a nuisance. They are soft and with the low profile they are not noticed or sleeping sideways, as a soil alternate. Spectacular battery. 14 hours in sleep mode is something that I can never check for myself. After seven hours of night use, when they woke up they still had about the remaining 50%. Passive noise block. Without active cancellation, but with the right tips they isolate surprisingly well. Reasonable, at least. Useful sleep monitoring. The application records sleep phases, number of turns in bed and preferred position. There is enough correlation with what it says My garmin on duration and phases. And then there are four other elements where they fail. Mediocre audio. That nobody expects audiophile quality. Nor is it the vocation of these headphones. The sound is functional, music lacks depth and warmth. Very limited pre -recorded sounds. There is some variety, but many sound compressed and artificial. The most effective are the noise of color (white, brown, pink). Application Faluta. He tells me that I slept 16 hours when the reality is that at seven hours I took them off and left them on the bedside table. I should understand that absolute immobility for nine hours cannot be equivalent to very deep sleep. In addition, it is not very intuitive when applying one way or another. Problematic tactile controls. In the dark it is easy to activate some function. About the application Falutathere is an example. I have not sleeping 11 hours possibly from the day before my birth. That lack of logic in detection is a negative point. Yes, you can see how much I move during the night: my wife says that 16 turns seems like a fairly reasonable figure. The data collected by the application. Image: Mockuuups Studio, Xataka. Also Atina that I am only able to sleep aside, and I have quantified what I already imagined: I usually sleep more towards the side of the edge. The final verdict The big question with these headphones is whether they really help sleep better. The answer, in my experience, is not. I did not notice differences between the nights with them sounding before sleeping and the nights without them. I thought That the scientific approach of pre -registered sounds would better induce sleep, but it has not been so. My Garmin data, with me every night, indicate very similar patterns with them and without them. And something worse when I tried to wear them playing all night, as I said before. At 150 euros are not cheap, but Yes I see them a clear target audience: the people who need to fall asleep listening to something. For that, I don’t think there are much better options for the low profile and night comfort. And without disturbing the bed couple, if there is. There I see an obvious sense. But for those who do not sleep wonderfully and look for allies of any kind to fall asleep, and not to simply hurry a podcast of True Crime Until we fall round, at least in my experience, these headphones do not miracles. Anker Soundcore Sleep A20, Sleeping headphones with noise block, small design for people who sleep from side, 80 hours of autonomy, Bluetooth 5.3, sleep monitor, personal … Read more

Aemet warns of the arrival of a new Dana, and is expected

Just a couple of days ago, weather models They began to glimpse The possible formation of a new isolated depression in height, a Dana, on the waters of the Atlantic. The observations are confirming the expected and now the experts warn of the arrival of a phenomenon that is expected intense. Special notice. The State Meteorology Agency (Aemet) has issued a special notice for storms and intense rainfall associated with the newly formed Dana. The situation will affect the northern half and third this peninsular between tomorrow 11 and Saturday, July 12. What’s happening. At the beginning of this week, meteorologists proved that the Peninsula had been divided between two air masses, one to the north, under the influence of vaguades and a mass of cold air, and another to the south with anticyclonic time in which heat resisted leaving. The days have passed and but the apparent return of stability and heat has been just a mirage, at least for part of the country. The reason is the decoration of a Dana, an area of ​​low height pressures that is separating from the cold circulation of the north. This Dana is being formed to the west of the Iberian Peninsula and will soon arrive by the atmospheric circulation itself. What we can expect. Aemet’s special notice speaks From the arrival of “high adversity storms in the northern and third half of our territory, accompanied locally of large hail, very strong wind and very strong showers.” Tomorrow, Friday 11, they await us according to the agency storms that would gain intensity from the afternoon both in the Cantabrian mountain range and in the Iberian system, and that they would go little by little by moving north or northeast. These storms could lead to hail of size greater than 2 cm in diameter and showers that would accumulate up to 30-40 mm in an hour, in addition to “very strong” wind gusts. On Saturday 12, Aemet sees “likely” that the Dana is moving to the east, which would take instability to the west peninsular and, especially, to the northeast quadrant. Uncertainty. The forecasts They point out the probable arrival of this extreme but Aemet event warns of a certain degree of uncertainty. As they explain, the probability that the arrival of the Dana has storms and intense rainfall is “very high”, greater than 70%, but not total. As they detail, “the described scenario is quite likely, the uncertainty inherent to this type of disturbances makes it difficult to specify the areas where a greater impact will occur.” Uncertainty increases the more we move away in time, but the agency estimates that the Dana’s passage does not have major impacts from Sunday, day 13.

Amazon does not expected Prime Day and launches some of the best chollos in Echo Packs, Ring and Fire TV Stick

As is usually the case in Amazon campaigns, the store did not want to wait for its next Prime Day 2025 to give a small advance that serves as a good snack of what is to come. On previous occasions we saw the offers arrive on many of its devices, but this time the thing has changed: The offers we can find in the store are lots or packs that collect some of their devices at a very good price. Of course, being exclusive offers, there is a condition: To take advantage of discounts, we must be signed to Amazon Prime. Fire TV Stick HD Pack by 48.99 eurosincludes the Dongle and an interior chamber ring. Echo Pop pack by 53.98 eurosincludes two Echo Pop speakers and an intelligent plug. Echo Dot pack by 71.98 eurosincludes two Echo Dot speakers and an smart bulb. Echo Spot pack by 123.98 eurosincludes two Echo Spot watches and an smart bulb. Echo show pack by 133.98 eurosincludes two speakers with Echo Show 5 screen and an smart bulb. Fire TV Stick HD Pack If you were waiting for a good offer in the popular Fire TV Stickits standard model (with HD resolution) is offer in a pack that includes an interior chamber ring. All this for a price of 48.99 euros. He Fire TV Stick it’s a Dongle which connects to the TV through an HDMI port to be able to have functions that we usually watch on Smart TVS (useful for old televisions). In this way, we can access the voice assistant Alexa or download Apps like Netflix or Prime Video. The Ring Camera (Indoor Camera of 2nd Generation) It is, as the name implies, a surveillance camera that offers live video and bidirectional communication. It is ideal to have pets controlled when we go on a trip, but also to have an extra safety at home. It is easy to install, it connects to Alexa and You can see the live video from the mobile and from anywhere. Fire TV Stick + Ring Cámara * Some price may have changed from the last review Echo Pop pack One of the best offers in Amazon lots is found in the Echo Pop packsince in this case we talk about a combo that includes two speakers and an intelligent plug. All this for 53.98 euros; That is, the pack is cheaper than if we bought only a pop echo. He Echo pop It is, so to speak, a more economical review of the Echo Dot (5th generation). Instead of a spherical design, in this case it has a semi -man -design and a Speaker offering high audio quality. It is also compatible with Alexa, has Bluetooth connectivity and serves as a center to build a home automation network. He P100MA tapo It is an intelligent plug that can be integrated into the Amazon ecosystem through Alexa, allowing to use the functions of said plug by voice commands. Among these functions, we have the Lighting and off the devices that we connect to the plug, we can create timers and routines and even allow us to be used even if we are not at home; Something useful if we are traveling and we want to know if we have left the plug on or off. Two Echo Pop + Tapo P100MA * Some price may have changed from the last review Echo Dot pack On the other hand, if we want the “older brother” of the pop echo, we can also find a good offer in the Echo Dot (5th Generation)which comes in this case with two units of the Amazon speaker along with a Tapo E27 bulb. All this for 71.98 euros. He Echo Dot (5th Generation) It is an intelligent speaker that has been in the Amazon store for a while, but continues to offer a very complete experience. Integrates the voice assistant Alexaserves as a center to build an intelligent network at home and, like the Echo Pop, it has Bluetooth connectivity, so many devices can be connected (I, for example, I use it with the Nintendo Switch). The Tapo E27 It is an smart bulb that integrates with Alexa so that their functions can be used by voice commands. It is a multicolored bulb that has 16 million tones to choose from and that allows routines and timers to program. Two echo dot (5th generation) + tapo e27 * Some price may have changed from the last review Echo Spot pack One of Amazon’s most curious (and most recent) devices is the echo spot, a kind of alarm clock that also includes a speakerwhich offers an assortment of additional functions to the other store speakers. In this case, you can find in pack with two units of the alarm clock and with a Tapo E27 bulb. Its price, in this case, is 123.98 euros. He Echo spot It is an intelligent alarm clock that also integrates the Alexa voice assistant and, of course, also serves as a center to build an intelligent network at home. Includes a screen to see the time, time and song we are reproducing And it allows to create routines to get up with certain songs that can be reproduced from Amazon Music, Spotify or Apple Music, among others. * Some price may have changed from the last review Echo show pack Finally, during the prime day offers, we can also find a good price in the Echo show 5which in this case comes in a pack with two units and, again, a Tapo E27 smart bulb. Its price in this case is 133.98 euros. He Echo show 5 (3rd generation) is an intelligent speaker that comes with a screen, an interesting point because it has quite particular functions. Of course, it allows you to see the time, the time and you can select the images that we want to reproduce, but also even allows to reproduce content of some streaming platforms.

I have tried day, the browser that replaces ARC and bets everything to AI. It hasn’t come out as expected

This story begins almost three years ago, in July 2022. That day I discovered ARC When it was little more than a beautiful idea with exclusive invitations. I tried it, it didn’t convince me. It was too different, too pretentious perhaps. I safari again without looking back. A year later, second chance. Same conclusion. Arc was still looking like that application that I wanted to teach me to navigate when I already knew how to do it perfectly. But The summer of 2024 was different. ARC not only convinced me, fascinated me. It became more than a browser. It was my productivity tool. Vertical eyelashes. The divided eyelashes. The spaces. The versatile elegance of your interface. The way I organized my digital day. ARC did not sail web pages. I built my workflow. The record date appears in the ARC adjustments. Almost three years since the first test. Image: Xataka. And then December arrived. Six months ago. Josh Miller uploaded a video to YouTube. “We are building something new,” he said. His name was day And it was the future of navigation. Arc, of course, would continue to exist, but with “minimum maintenance.” The typical business phrase that means gradual abandonment without saying it explicitly. The Arc community It exploded. Justly. They had built something beautiful, had achieved a passionate user base, and decided to start from scratch. To pursue the chimera of AI. A week ago I managed to try it. It is not yet in its final version, but I wanted to prove its foundations. My expectations were low, but not my curiosity. You open day and see Chrome. Chrome Bonito, Chrome Pulido, Chrome with better animations, but Chrome after all. EITHER ChromiumOh. The traditional horizontal interface. The address bar above. The eyelashes where they have always been. No trace of divided eyelashes. This is day. Tabs, address bar, etc., where they were always before ARC. The differential proposals of ARC, absent. Image: Xataka. Everything that Arc had revolutionized, back to conventional design. The difference is in the right sidebar. An integrated chatbot. A conversation interface that can see what you are seeing, that you can read your eyelashes, which supposedly understands your context. Is chatgpt, but with access to your browser. The idea is seductive. Imagine being able to ask your browser what that complex graphic that you are seeing, or ask you to summarize the five articles you have open, or help you write an answer based on all the information you have been reading. The perfect context for perfect assistance. What we have seen in other browsers, but from the roots, not as later patch. Image: Xataka. Reality is more mundane. I asked Dia Dia about the content of the in front of the tab. He made me a suggestion that made no sense. I spent a screenshot to refine your context. He gave me a meaningless advice. I tried to summarize articles that, praxis – had text integrated into images. He couldn’t read them. He invented answers that were feasible, but not true. And did what any Llm He does when he doesn’t know something: pretend he knows and build a very convincing lie. Dia chatbot uses an OpenAi API after all. It is the problem of these tools: when they do not know, They don’t say “I don’t know.” They improvise. When you are an expert in the field, the fighter on the fly. When not, they can strain it to you. AND Then there is the worst: what is missing. There are no vertical eyelashes, no spaces to organize projects, or almost nothing that made Arc great. I wish they include it. But the first glance is a jug of cold water. Day is what Arc was never: conventional. Business logic is understandable: ARC was too sophisticated for the average user. He had a pronounced learning curve. His best functions were used by a minority within another minority. The mass market continues to use Chrome because it is simple, familiar, predictable. Convenient. Día tries to be a browser that anyone can use from day one, but with integrated. The plan must be to capture users who would never have bothered to learn arcbut they would use an improved chrome with the native. The problem is that it already exists. Or it will exist soon. Is called Chrome and is integrating Gemini. Is called Edge and has co -driver. Is called Operates and integrates ia tools own and others. Day is late for a party already started and without a proposal as differentiating as Arc. Day responding well a consultation. It is more useful in long pages or documents, where to locate concrete information is more tedious. The problem is that it bases its differential point there, on saving one copy and paste in another chatbot like Chatgpt. Or assume that this is not possible out of day. But it is. Image: Xataka. If we take away the marketing and elegant presentations with garamond and transparencies, Day is a standard chromium with a chatbot in the sidebar. That’s all. Everything that makes it special is AI, and that AI is not special. It’s GPT reading your eyelashes. You can also invoke several of a tacada. Useful, surely. But little revolutionary. Meanwhile, ARC is withered. Officially, “in maintenance.” Without new features, without evolution. Those of us who fall in love with their unique value proposal have been abandoned in favor of pursuing a market that perhaps does not exist. Or that is occupied by larger ones. It is the brilliant object syndrome taken to the business end. ARC had problems, true. The Windows version was much lower, mobile synchronization, very limited; the Bugs They still appeared and some characteristic seemed to implement. But it had a clear identity and a unique value proposal. Era –es– different for good reasons. Day is different by defer. His AI is today his only letter. In fact Your video tutorial It goes on how to use the … Read more

Even so, he is going better than expected, and the key is in user pocket

There are companies that appear everywhere, which have millions of users, which seem unbeatable. But behind that dazzling popular there is a fact that is often overlooked: They are not profitable. Some have been growing at full speed without ever generating benefits. Openai is one of those cases. His name is on everyone’s lips since Chatgpt He went into the world in 2022. But the truth is that, economically, he is still far from quading the accounts. Spend much more than you enter. And it will not be profitable for several years, if they are fulfilled Your own calculations. The paradox of success that does not give benefits OpenAi is everywhere. And chatgpt too. In just over two years it has gone from being a technical rarity to get into mobiles, computers and conversations. But that something sounds a lot It does not mean that it gives money. In fact, the accounts are still in red. Because the phenomenon is real, yes. But so is the expense. Training increasingly large models, keeping servers working and hiring talent is not cheap. According to The InformationOpenai would have lost about 5,000 million dollars in 2024. And this year the thing does not look much better. It is not a unique case. Spotify was founded in 2006 and It took twelve years to see benefits for the first time. Twelve. And only in 2024 managed to close A full year in positive. Have millions of users It does not guarantee May a company be profitable. Openai does not seem to be close to balance, but there is an important difference compared to a year ago. According to Financial Timesyour subscription income has shot. It has gone from generating $ 5.5 billion to approach 10,000. Half of that money comes from users who pay for chatgpt. Telegram’s case also helps put things in perspective. The application was born in 2013 and for more than a decade operated without generating benefits. Only in 2024, after exceeding 900 million users, Finally reached profitability. It took eleven years. Openai aims to follow the same path, but at another pace. The company already has told its investors that does not expect to be profitable before 2029. And for that to happen, it needs a very concrete figure: reach 125,000 million dollars in annual income. The company has already told its investors that it does not expect to be profitable before 2029. It is an ambitious objective, especially if we take into account that today is around 10,000 million. For multiply by more than ten Its turnover, OpenAi not only trusts that more users subscribe to Chatgpt, but that much of their income is related to their API. When we talk about the API we are referring to the system that allows you to integrate OpenAI models into third -party applications. Companies of all kinds, from banking to health, which can use various models of the company, such as GPT-4.1, to improve their benefits. Another important source, According to The Informationthey would be the calls Artificial Intelligence Agentsmore sophisticated tools that not only answer questions, but do complex tasks autonomously. Openai wants this to become its great premium product. It should be noted that many of the great technology (Microsoft, Google, Tesla) quote on the stock market and publish each quarter accounts. That forces to generate official reports, audited data and financial transparency. Things are different in the startup led by Sam Altman. OpenAi does not quote on a stock market and adopts a hybrid model: a non -profit entity (Openai, Inc.) controls a subsidiary with limited profittoday in the process of becoming in a public benefit corporation to capture greater investments than those received. Not being obliged to publicly audit your commercial accounts, OpenAi does not publish official figures. There are no quarterly reports of income, costs or losses. This is usual in many US private companies, which have greater financial confidentiality. Therefore, when we talk about current Openai numbers, we do it supporting ourselves in leaks, in Media estimates such as The Information or in data that the company itself shares selectively with investors. There are no periodic official reports, because they do not exist. There is no doubt that Openai has achieved something huge: he has put generative artificial intelligence in everyone’s mouth. But that does not guarantee income, much less benefits. Touch to wait to know if the company will meet its goals. For now, it seems to be on the right track.

The United Kingdom tested its sophisticated defense simulating the day of Russia’s invasion in Ukraine. Did not go as expected

Simulations are an essential part of the network of nations defense. We have a large number of examples, from the “game” that They used in the Cold War The United States and Russia to conclude that it was not worth test try your last destroyer against Washington, or those who He has activated Taiwan In recent times “for what can happen.” The United Kingdom also carried out a test that should confirm that its arsenal is ready for battle. The conclusions were not exactly those. A brutal lesson. The story took place a while ago. As we said, the United Kingdom carried out a Strategic simulation of very high importance: he replied in his own aerial territory the exact pattern of the first Russian attack on Ukraine, which occurred on February 24, 2022. He did it through the Gladiator Training Systemvalued at 24 million pounds, and with the aim of evaluating how their defenses would respond if the same type of onslaught would have had the British soil as white. The conclusion It was alarming. Although the results were not revealed in detail, the then commander of the Air Battlespace Training CenterThe Blythe Crawford Air Comodoro, was bluntly describing it as “a very beautiful panorama.” For a country that for decades felt protected by its location to the western edge of Europe (with the continental mass acting as mattress natural against threats), the exercise was a strategic shaking that threw old assumptions for land. A threat that is no longer distant. Then it was more known, mainly than the exercise revealed vulnerability from the United Kingdom before a massive and modern air attack like Russia used against Ukraine, with a devastating combination of missile, drones and autonomous technologies. Crawford also stressed that Ukraine made everything West will awaken. The conflict not only exposed the brutality of the first Russian blows, but also highlighted how modern war has transformed the rules of aerial domain, such as We have been counting. Crawford explained that it is no longer about achieving aerial superiority in broad and sustained terms throughout an operations theater, but to assume that supremacy can be Fragmentary, ephemeraleven located between two trenches or just a few meters from the ground. The war in Ukraine, he said, is an unprecedented battlefield between two countries with powerful air defense systems, but where none has achieved A full domain of the heavens, in contrast to the predominant aerial doctrine of the last decades. The swarm that comes. One of the most revealing points of Crawford’s intervention was his analysis of the massive drone use In Ukraine. For the high command, it is no longer simply individual devices: now they face hundreds of hundreds of units, many of them equipped With explosivesothers designed as lures, and others Simply kamikaze. These waves, combined with rockets and intercontinental ballistic missiles, configure a type of multiple, simultaneous and heterogeneous threat for which traditional defensive systems were conceived in much more predictable scenarios. The tactical dilemma, In his opinionIt is clear: “Should all attack vectors neutralize or prioritize the most lethal?” A question without a definitive solution, but that affects all the Western air forces. Of strength to vulnerability. One of the most forceful messages of the United Kingdom simulation was the need to change the defensive mentality of the nation and its allies. For decades, modern wars were fought away from the national territory, which led to an erroneous perception of domestic security. Hence, Comodoro warned that it is time to abandon that trust and assume that even the British bases are now under direct threat. In other words: the United Kingdom cannot be considered as a simple safe starting point for foreign operations, but should be thought of as a potential objective and prepare as such. The risk, In his opinionIt is not hypothetical: if Russia decided to launch an attack against British soil, it could do it through its northern fleet from the Atlantic, thus avoiding European airspace. Redrawing doctrines. The last of the legs to deal with the simulation results. The Ukrainian case is rewriting military doctrines that during generations were considered unquestionable. The notion of total air control, cornerstone of NATO strategy from the Gulf War, seems to be eroding for a New generation of threats which combines speed, volume, unpredictability and autonomy. For Crawford and many other strategists, the key is to learn quickly, assume that the scenario (in this British case) is no longer immune, and rethinking defense systems as if the next attack did not happen in a distant country, but in “house.” Image | US Department of Defense In Xataka | The countries with more combat tanks, ordered in this graphic developer In Xataka | Satellite images have revealed what happened to one of Russia’s biggest arsenals.

There is a critical sector that is still expected the worst before the tariffs of the United States: that of medicines

For three decades, pharmaceutical products have enjoyed green light in international trade in terms of tariffs. However, the commercial war unleashed by the tariffs of the new US government does not understand essential products. Change of course. Upon yesterday, President Donald Trump announced A 90 -day truce to the introduction of tariffs in many countries. Did it one day After ensuring During the National Committee of the Republican Congress an upcoming introduction of “Great tariffs”To the pharmaceutical sector. This raises an unknown to the European pharmaceutical industry, whose immediate future depends on whether this moratorium also means a pause in tariff fever that this week promised specific rates to this sector in principle exempt from tariffs that affect general trade. An industry with its own rules. And until now the pharmaceutical industry had enjoyed tariff exemptions under the Agreement for Pharmaceutical Products of 1994 of the World Trade Organization, agreement in which the European Union, the United States and other countries such as the United Kingdom, Switzerland or Japan participate. The agreement eliminated tariffs and other surcharges in a variety of drugs and pharmaceutical products. Tariff war. All this is part of the context of a commercial war unleashed by the new US tariffs. Although the tariff issue raised months on the table, the storm broke out last Friday when Trump announced outside the White House the amount of “reciprocal” tariffs that would be taxes to each country (already the European Union). Yesterday, when the tariffs seemed to come true, the president of the United States turned back (more or less). He did announcing 125% tariffs on Chinese products and a 90 -day moratorium on other countries. “Fast and radical” action. Trump’s announcement of industry -specific tariffEuropean Federation of Pharmaceutical Industries and Associations), appealed to the president of the European Commission, Ursula von der Leyen, take actions “fast and radical“Aimed at avoiding the” risk of exodus “of European producers to the United States. On the other side of the puddle, analysts do not see this hypothetical exodus clear. “Although the details are scarce, we are strongly opposed to tariffs to any pharmaceutical product: these will probably do little to bring their manufacturing again to the US.” pointed to Reuters Evan Seigerman, BMO Markets BMO analyst. “Given the complexity of the pharmaceutical supply chain, we do not expect the industry to make substantial changes.” Ozempic, in the eye of the hurricane. In recent days, Lars Fruerd Jørgensen, CEO of Novo Nordisk, has also spoken, the company he developed Ozempic and Wegovy. The Danish company manager expressed a certain degree of concern: “Of course there will be short -term impacts while mitigating the impact of tariffs,” collect Bloomberg. Ozempic’s case is relevant. On the one hand, for months we have seen how the demand for this drug against diabetes converted into weight loss treatment far exceeded its offer. The Danish recipe has, on the other hand, with a competitive formula created in the United States, the tirzepatida we found in Zepbound and Mounjarocreated by Eli Lilly laboratories. The manager also put the focus on generic drugs. “As much as the highest category of drugs is that of generic medicines,” It also pointed to Bloomberg. “If you put tariffs, it is difficult for me to see that it will not lead to another situation of medicine shortage or in general to an increase in prices.” Despite this, the United States closely follows the future of prices of this drug to the point where they have spread Bulos on false tariffs To this product. From Australia to Spain, through India. The question of the genericians has had echoes in distant countries such as India and Australia. In the “Aggravic list”Commercial of Spain, the pharmaceutical issue was manifested in a concern for pricing measures in pharmaceutical products, among other issues. It is not only Spain: in Australia, the PBS program (Pharmaceutical Benefits Scheme) has been at the center of the tariff discussion. This mechanism dedicated to the pricing of pharmaceutical products homogenizes drug In an article for The conversation Deborah Gleeson, from the University of La Trobe. A key country in all this is India. This country is an important drug supplier for US pharmacies. Asian giant producers They fear that tariffs raise the price of their products, which will ultimately lead to a product increase in the US market.

CERN physicists believed that symmetry between quarks up and down is broken. Is much more than they expected

The quarks, the elementary particles that constitute the protons and neutrons of the atomic nucleus, are fermions. And the electrons, too. There are several typesalthough physicists like to talk about ‘flavors’: up (UP), below (Down), charm (Charm), strange (Strange), Cima (top) and background (Bottom). The most frequent in ordinary matter They are the quarks up and downalthough top is very interesting for a curious reason: it is The heaviest elementary particle that we can find in nature. An interesting note since we move in the field of fermions: supersymmetry is a theoretical model of particle physics that proposes the existence of a hypothetical particle that is matched with each of the fundamental particles we know. PSIANS EXPLAIN THE EXISTING RELATIONSHIP Among the bosonsthat have a spin with whole value, and the fermions, which have a semientero spin. However, it is important that we do not overlook that it is a hypothetical theoretical framework that, therefore, has not yet been observed in nature. Not even experimentally. Physicists still do not understand how quarks and gluons combine The strong nuclear interaction, which is one of the four fundamental forces of nature, is the “glue” that keeps the quarks together to give rise to protons, neutrons and other hadrons. It is also responsible for the cohesion and stabilization of the nucleus of atoms. Until now, particle physicists considered that this force interacts with all quarks, regardless of its flavor, in the same way. This mechanism is known as isospin symmetry and respects, yes, the differences that exist between the masses and the electric charges of the quarks. A kaon is a subatomic particle constituted by a quark and an antiquark, but not by any quark; It is a strange quark According to Isospin symmetry, the collision of heavy ions, which are atoms or molecules that have acquired positive or negative global electric charge due to the loss or gain of electrons, should essentially generate the same amount of kaons with electric charge and neutral kaons because The mass of the quarks up and down is similar. An note before moving forward: a kaon is a subatomic particle that is constituted by a quark and an antiquark, but not by any quark; It is a strange quark. The presence of the latter gives them very peculiar properties, so studying them is very useful to understand the characteristics of the subject a little better. What has surprised CERN physicists is that The Na61/Shine experiment has evidenced that Isospin’s symmetry is not fulfilled. And does not do so because heavy ion collisions generate a very large imbalance between the production of loaded kaons and neutral kaons. In recent years, physicists suspected that a certain degree of imbalance could be given, but what they did not expect is that this difference was so great. This is very important for a reason: current theoretical models have difficulty explaining it. It may seem like a problem, but it is not at all; It is an opportunity. In particle physics when such a discrepancy appears What is happening in your experiments. This particular disparity has the ability to help them better understand how strong nuclear interaction works and how quarks and gluons are combined to give rise to the production of hadrons.

V3 earlier than expected, but with half a capacity

The two consecutive explosions of Starship, related to the design changes of its V2 versionThey have made SpaceX to readjust the highest rocket roadmap in the world. As usual, we have learned for a message from Elon Musk in X. The message in question. “We are making the design of Starship v3”, Musk wrote. “Spacex is on its way to achieving a launch rhythm of a starship per week in approximately 12 months.” “Each one will put about 100 tons of Starlink satellites in its fully reusable version. It will be a transcendental advance.” Context. He Starship rocket It is in tests and has not begun to launch satellites. The current design does not exceed the load capacity of a Spacex heavy falcon. When Elon Musk presented the V2 and V3 versionsdescribed a radical leap. They would be higher, totally reusable and with an unprecedented power in the space industry. Starship V2 would grow up to 124.4 meters high and could place more than 100 tons in orbit in its fully reusable configuration (that is, recovering both the super heavy propeller and the ship). Starship V3 would grow up to 150 meters high and place more than 200 tons in low orbit in reusable mode. The changes. Musk’s message suggests that Spacex has focused its efforts on Ultimar Starship V3 after incidents of the last two tests. Although Starship V2 has not fully materialized (on flights 7 and 8, a Starship Block 2 ship threw itself on a super heavy block 1), something does not go well with the second block of rocket improvements. The change of plans is reflected in which Starship V3 will have half of the planned load capacity. Specifically, 100 tons in its reusable configuration is what Spacex had announced for Starship V3. What happened to Starship V2. The second version of the ship has flown twice (Starship 33 and Starship 34) with the same result: leakage and explosion in the ascent phase, before the motion off. The new design has a defect that produces an excess of vibrations in the lower part of the ship, which causes the propellant tubes to break and have leaks. On flight 7 caused a fire and on flight 8 the explosion and loss of several engines. Waiting for the Raptor 3. Despite these problems, there is a new Starship V2 flight scheduled for April. Starship V3 will have to wait for New Raptor 3 engines 3 are ready. The new engines have more thrust and incorporate an integrated cooling system that eliminates the need for an external thermal shield.
