China built the largest high speed network in record time. Now you want something more difficult: improve it

by

China has already shown that you can do what no other country has achieved: display in record time The largest high speed network on the planet. But it is not enough to have it. The new challenge is even more complex: to improve it, make it more efficient, more connected, more useful for the economy. And that demands less colorful, but equally ambitious decisions. To grow quickly to grow well. Between 2021 and 2024, China added 10,000 Kilometers of track to your high speed network. The figure impresses, but it is no longer what defines success. The Ministry of Transportation has made it clear that the current objective is not to extend the railway map without pause, but to squeeze its potential. In fact, The country has set As a goal to reach 50,000 operating kilometers before the end of 2025. The network adds 48,000 kilometers, more than 70 % of the world total, and connects 97 % of cities with more than 500,000 inhabitants. Millions of travelers, but there is still a margin of improvement. Only in the first half of 2025, Chinese high -speed trains They transported 2,240 million people. The figure impresses, but the authorities are not formed. The objective now is to make this system more comfortable, more predictable and better coordinated with the rest of the transport ecosystem, from the urban metro to airports. High speed yes, but also logistics. China wants its high -speed trains to cease to be just a solution for travelers. The new approach includes routes adapted to the transport of goods, interconnections with airports and sea nodes, and improvements to integrate the system into the production chain. What is at stake is no longer only mobility, but the country’s competitiveness. Beyond traditional rails. While the current network is kept, China develops new generations of trains, such as magnetic levitation. These advances do not seek to replace what is built, but prepare for a future where speed, autonomy and sustainability are key. The country has already tried prototypes that reach 600 km/h In cities like Qingdao. Figures that impress. Security that holds. Moving millions every day with punctuality is an achievement. Doing it without major incidents, for years, it is even more. China has built a network that not only runs quickly, but aims to resist earthquakes, storms and overloads. According to Xinhuasince 2012 no serious accident has been registered in the high speed network. Centralized planning. Faced with chronic delays that affect many countries, China has maintained a clear strategy: centralized decisions, sustained investment and state control of the process. It is not a perfect model – there are errors, cost overruns and debatable decisions. But its results in deployment and integration are difficult to ignore. A mature network, a major challenge. As we have seen, the Asian giant continues to expand its network, especially towards interior and less connected regions. However, it is no longer just about adding cities to the map. The real challenge is another: to ensure that a gigantic infrastructure works better and better, with less margin of error and more logistics demands. The stage of the big deployments is giving way to the stage of precision.

If you also feel that you do not have so much time to read as you would like, there is a solution: the “fast reading”

by

I confess that Bill Gates gives me some healthy envy. Not just to have A current account which looks like a phone number with so many figures, but for its ability to Read more than 50 books a year. I have tried and it has been impossible for me. But Do not shoot the towel. Scientific evidence revealsthat there is a balance point between the speed of reading and the ability to understand and retention of the content that is being read. However, with adequate practice, that balance can be improved by accelerating the reading speed without compromising Reading understanding. Research Like those of the University of Guayaquil, they conclude that the reading speed can increase significantly with the practice and use of appropriate techniques. An average reader reads between 200 and 400 words per minute, while through rapid reading training, that speed can reach speeds of up to 1,000 or 1,700 words per minute. Strike a balance Fast reading is especially useful for processing long texts superficially, being useful for obtaining general ideas or punctual information. It is not recommended in contexts where a deep understanding, detailed analysis or memorization of the content is required, but when it comes to seeking specific information or in texts that address subjects of which previous knowledge is already had. The main ones involved in a slow reading speed are: Subvocalization: It is the habit of mentally pronouncing the words that are read. That limits the reading speed since the visual image of the word that interprets the brain is vocalized as if you are reading aloud, undergoing the need to vocalize each of the words and not limit itself to the compression of it. Word reading by word: The global understanding of the text decreases. Regression: reread several times or have to search in the next line of text as it breaks the reading flow. Low concentration: It affects both speed and retention. Quick Reading Techniques Science reveals that this speed increase is not a magical process, but the result of the conscious training of eye movements, vocabulary expansion and the use of strategies to improve global understanding, and not only the amount of words read per minute. 1. Fragmentation This technique is to avoid reading word by word and assimilating the Words by groups. For example, to start training, you can group the words of the phrases of two by two and increase the number progressively With practice. At first it may be a bit strange, but the brain recognizes the words for its morphology, which explains, for example, that you Cberreo Pdeue Read Etse Txeto. If you read it Word A Word would cost you more than in block because a word contextualizes its adjacent. This principle makes your view jump between words, not word in word during reading. The usual thing is to start reading like this:In-a-place-of-the-scan-of-whose-name-no-quiero-alleging But with a little practice, we soon start reading like this: ANDn a place-of the stain-of whose name-I do not want to remember With proper training, the number of “pauses” is reduced: In a place in the stain-of whose name I do not want to remember. 2. Use a visual guide The rupture of the reading flow is one of the most frequent causes for reading the reading. This usually happens when you have difficulty finding the following text line. The solution: as simple as using the finger to indicate the start of the next text line or an equivalent visual guide. On screens you can use the mouse pointer as a guide. If you prefer Read on mobiles or tablets, the edge the screen or any other reference can contribute to the view not to hesitate when looking for the next line and the reading inertia is maintained. 3. Be faster than voice If when you read you listen to the words in your brain, you are not reading quick enough. As we have said before, this phenomenon is known as subvocalization. To avoid this, it will be necessary to train the reading speed trying to read faster than that inner voice is able to vocalize. In doing so, it will be forcing the brain to prioritize visual processing instead of the “auditory” of your internal voice, thus improving the reading speed. 4. Infinite look Like any other muscle, ocular muscles should also be exercised to improve reading speed. One way to improve your performance is to practice infinity to get a visual sweep of the most efficient text. This technique consists in drawing the infinity symbol (∞) on the text block, so that the look runs in a more global way, not line by line, and improves the capture of words by blocks.

Spain produces more solar energy than ever, but it only gets a cheap time of electricity a day

by

In full July, with the air conditioning Working tirelessly and The tuned light billin Spain there is a single moment of the day when electricity consumption does not hurt so much in the pocket. That little energy respite is concentrated at noon, a time strip in which electricity costs half or even less than in the rest of the day, but why is it just time? The fire triggered. On Wednesday, July 16, the average price of electricity had been in the € 164.06/MWh at the regulated rate (PVPC), According to data from Electrica de España. For this Thursday 17, a slight drop is expected to € 102.85/MWh, but that half hides an unequal reality: for much of the day, the cost exceeds 120 euros per megavatio hour, As the Iberian energy market operator has collected (OMIE). Only for a single hour there is a “affordable” price. In just seven hours, electricity will go from relatively affordable to almost double its price. At 15:00, it will cost € 73.00/MWh. At 22:00, it will reach € 129.85/MWh. The explanation is not in a peak of consumption, but in a change of source: the sun is exhausted, the gas enters and the market reacts. Why only in that time strip? The reason is in the sun. From three in the afternoon, the solar production curve increases considerably. The electrical system then enters an overoferta phase: there is more renewable generation than real demand. This surplus translates into an abrupt fall in the price in the wholesale market (‘pool’), which reflects in real time the imbalance between what is produced and what is consumed. The problem is that this surplus cannot be stored properly. Spain still does not have batteries No infrastructure sufficient pumping to save That cheap energy and release it when it is most needed. Thus, the system is forced to sell cheap at noon and buy expensive at dusk. To this lack of storage is added a less visible problem: he Curtailment. Although more renewable than ever, part of that energy is lost due to saturation of the network. According to Red Eléctrica, in some knots of the central-south peninsular-such as Arenas de San Juan or Caroyuelas— It has wasted up to 30 % of the electricity generated due to lack of capacity to evacuate it. Meanwhile, the price of light continues to rise. This schedule imbalance generates what experts call a daily “spread”: a price difference that can exceed € 200/MWh between the cheapest time and the most expensive of the day. It is what makes an invoice shoot although part of electricity is generated almost free. It is not just guilt of the sun. The price of light not only depends solely on solar radiation. From the blackout of April 28, Red Electrica has activated A reinforced operational modewith more weight of the combined gas cycles to stabilize the network. This emergency measure It has become the new normality While structural reforms are implemented that will not be ready until next year. The direct impact on the invoice. Consumers with regulated rate (PVPC) are the most exposed to this volatility. Every day, your bill depends on the price hour by time. But even free market customers are noticing uploads: some electrical companies are transferring the contracts to the contracts, As Facua has warnedwhat could be illegal if it is not foreseen contractually. With this panorama, many consumers try to concentrate the use of appliances such as washing machines, ovens or air conditioners during that cheap time of the day. However, not everyone has room to reorganize their life around a single low cost strip. The solution is more than clear. In this environment we have spoken many times: it goes through More energy storage, greater demand management, More local micro -redes and best interconnections with Europe. The government already has launched Royal Decree-Law 7/2025 To accelerate these changes, and has initiated the creation of a capacity market to guarantee the supply. But none of these measures is immediate. Some have deadlines until September, but others will lengthen until mid -2026. Meanwhile, the gas dependence will continue to mark night prices. A race against clock. Every day, the Spanish electrical system offers a single cheap electricity window. It is the reflection of an energy paradox: there has never been so much renewable energy, and it has never been so difficult to take advantage of it efficiently. As long as storage and flexibility deficiencies are not resolved, the cheap time will be a timely privilege and not a guarantee. In a summer marked by heat waves, the cost of not acting on time will be measured not only in euros, but also in emissions, social vulnerability and energy dependence.

Drones are revolutionizing war in real time and Europe already has its following evolution: the “hybrid” drone

by

The drones are Very present In war. The UAV (unmanned aerial vehicles) have proven to be versatile and competent tools on the Batallo field both in the offensive and in intelligence, but they have an important limitation: when they are on land they are useless. A small drone can get through a window and check a room, but it has no wheels to sneak into recesses in terrestrial operations. Not being, of course, it is a Rooster. A what? A Rooster. This peculiar “hybrid dron” is manufactured by the Israeli company robotic and stands out, as it is obvious, for its form factor. Unlike conventional drones, which can usually only fly, Rooster can fly and run thanks to a side wheel system. They are not really wheels as such, but a kind of cages that, on paper, should pay correctly even on complex land. Teams of three. This drone can be operated independently or in teams of three. When they come together, the three drones forms a mesh, interconnect with each other, share sensors (such as cameras) and can be controlled by the same operator. In fact, this can see in real time the image of drones on the control screen. This connectivity is key, especially if there are no GPS signal in the area. More Specs. The device weighs 1.6 kilos and is to be able to transport loads of up to 300 grams, such as a radiation sensor or a thermal chamber. Its autonomy is 12 minutes of flight and 30 minutes on ground. Seeing it in operation is, at least, curious, since it can pass another in real time, which allows to explore a plant on the ground, fly over the sale, climb to the second floor flying and return to the land exploration. It has cameras (night vision included), records even in Fullhd and, of course, it has ia to detect obstacles. The Rooster flying | Image: robotican In the hands of Israel … and NATO. This drone has already been adopted by the Israeli armed forces, but now it is ready to make the leap to the international market. Just three days ago, the Rooster got he NATO STOCK NUMBER. This is a 13 -digit code used by NATO that guarantees that all objects, from a bulb to pants, are cataloged and are easily accessible in supply chains. Also, in some way, it determines that they are trustworthy devices and that they meet the standards of the alliance. The company also confirmed that has sold its drones to “elite units in Europe”, not to mention exactly countries. We do know that, currently, they are employed by Israel’s defense forces and By the American Dea. The Spanish army He also had occasion to put the rooster tested during a demo that took place in forum 2e+i in Toledo in 2023. The rooster on land | Image: robotican The current context. Israel, One of the world’s great weapons manufacturersIt is not a NATO member country, which adds 32 members, but a partner through the 1994 Mediterranean dialogue such as Jordan, Mauritania or Morocco. The relationship with this country at this time is tense. On the one hand, he has the United States as a great ally, to the point that Israel is considered a MNNA (Important not-oan ally). This designation is made by the United States government to those countries that it considers closest allies. Israel was one of the first five countries to be part of this list after the creation of the MNNA level in 1987 by Ronald Reagan. On the other hand, there is the European Union, which He has condemned Israel’s acts in Gaza and supports the Palestinian authority, but still without agreeing on what measures take against Israel. Some countries, including Spain, defend that agreements with Israel must be suspended and advocated by taking measures and By a arms embargo. The future is the remote control. If something has made clear the recent events that have shaken the international geopolitics, in particular the Israel-Palestine conflict and The Ukraine Warthe thing is Drone control It is capable of decant the balance and make a difference. Unmanned vehicles allow precise maneuvers without putting military personnel at risk. Having more versatile options, such as a hybrid drone capable of developing on land and air, opens many possibilities and supposes, without a doubt, an advance.

Every time someone tells me that his mobile is slow, I know where to look: the “paper” of WhatsApp

by

WhatsApp’s storage is something problematic for a long time. So much that, over time, those responsible have had to develop different forms of release conversations spacevideos, photos and audios on our smartphones. Today they are enormous help, because I have proven that unless we install giant games or we love to carry a good videos library in 4K, the greatest enemy of our mobile is the WhatsApp download folder. Every time someone tells me that his mobile is slower, the first thing I do is look at how much free space he has. And bingo: WhatsApp is usually The biggest glutton in iOS and Android. WhatsApp tricks and tips to hide you to the fullest and maintain your privacy WhatsApp vs Storage, a not solved historical conflict. WhatsApp problems with the space occupied by their files come from the time when the iPhone had 8 GB and it was normal for Android to use internal storage and microSD cards. “That is the solution, more storage,” we thought. But no, unlike Companies like Samsung and its ‘hacks’WhatsApp never allowed their files to move to secondary memory, so releasing memory was generally deleting files or moving them. In the latter case, however, they stopped appearing linked to our conversations. That storage devourer called WhatsApp. A full mobile, a slow mobile. As the storage is filled, the performance of a low device. It is so in telephony, in tablets, in classical computer science or on televisions. An operating system and its applications need a minimum space to execute reading and writing operations. When the storage is almost full, modern systems try to release space by erasing caches and other temporal files, but where there is not, it cannot be taken out. In computers it was also important to have free space for the use of virtual memory, but with the Virtual RAM extension which include many manufacturers, the problem is also aggravated in mobiles. The recommendation: Disable this function That neither Google itself advises to use, because it wears the memory. In 2025 there are good solutions. Unlike what happened in its beginnings, today WhatsApp does have Good solutions to free space. Before looking at a capture like the superior, it meant frustrating and deleting video by video, photo by photo. Today, after detecting that a mobile is so full, the first thing I do and advise is, inside WhatsApp, go to ‘Settings – Storage and Data – Storage Administration’. Once we have selected the files to erase, the right appears down to the right. There we will find ourselves A complete menu where the application informs us how much space is occupying and how it distributes it. First, it shows, without ordering, files of more than 5 GB. Entering is a great filter to find some large attachment that will quickly help free space. It is also very useful the ‘forwarded of many times’ section, as it is very common for us to get the same video forwarded from different groups, and WhatsApp duplicates them. If we scroll, we will reach the space occupied by the conversations of our individual groups, chats or channels. By selecting each of them, we will see which files occupy more by order, and we can make a quick selection and delete, from the paper icon to which the red arrow of the upper image points. Get to reach this point. Deciding what to delete can be exhausting, no matter how easy the WhatsApp assistant is given to us. So it is best to avoid a situation in which WhatsApp ‘eats’ 32 GB, as in catches. How to achieve it? WhatsApp itself gives us the advice: ‘Activates temporary messages’. If we do it in our groups or chats, the messages will be deleted after 24 hours, 7 or 90 days, according to us. The occupied space will also be released after that time. If we want everything to still not be deleted automatically, but we want to better manage space, in ‘storage and data’ we can also Disable file automatic downloadchoosing according to file type if we want nothing to be downloaded automatically (which would be the ideal option for WhatsApps full of photos of groups that we do not consult), or only in Wi -Fi or Wi -Fi and mobile data. In ‘Settings – Storage and Data – Automatic file download’ we find the option to choose which files we want to be downloaded automatically. If we select ‘never’ we will totally control what our space is invaded and what not. On the iPhone, personally, too unleash the option ‘Save in photos’ that we find in ‘adjustments – chats’. I do it because that function makes all WhatsApp photos also go to the reel of iOS, which doubles them without any use for me. Other people, yes, choose to activate it for backup apps such as Icloud or Google Photos keep everything in the cloud. This WhatsApp option in iOS avoids duplicate files on the reel. If the deactive, the photos will continue to be on WhatsApp equally. More radical solutions. That WhatsApp storage can become a problem is not something invented. Personally, I have come to deal with mobiles that had 70 GB occupied by WhatsApp. When he has come to occupy so much, and we do not mean goodbye to everything, there is a magnificent more radical option such as ‘Export Chat’, which generates, if we want, a file compressed with all our conversation (in flat text) and all our files. In each of our conversations and chats we can export the historical content, choosing to save files or only the text. The pity is that there is no import option. It works very fast, so in seconds we can have the file in our memory, ready to be sent to a PC where we can have all the text, audios, videos and other files in the group. The background problem. WhatsApp is eaten a lot of storage, it’s true. But the real … Read more

When the bosses already value at the same time they do not work in your free time

by

More and more companies recognize the importance of their employees Disconnect from work to improve your well -being and Avoid exhaustion. After all, it suits them since that way Improve productivity. However, a New study It has confirmed the existence of a significant contradiction: although managers value their employees to take breaks and maintain a good balance between working and personal life, they usually penalize those who make use of those limits. The detachment paradox. The study carried out by researchers from the University of Science and Technology of Hong Kong and the Spanish IE Business Schoolanalyzed how managers perceive employees disconnect of work in your free time. “We only analyzed what happens when the worker should not work, such as the afternoons, on weekends and vacations,” said Elisa Solinas, co -author of the study. OK To what is published in Hardvard Business Reviewthe experiment had 7,800 participants, in which managers evaluated fictional employees who in a version took measures to disconnect from work and in another not. The results showed that, in their reports, managers recognized that those who disconnected from work during the weekend, returned with more energy and better performance. However, in the evaluations, they constantly described them as less compromised, even if they were more productive than those that did not disconnect. Even if you are the best, do not rest. The data suggest that the feeling of reproach of managers towards employees persisted even when the employee was a direct subordinate of the manager, when the employee who was disconnected was objectively better in his work and even when he disconnected for a justified reason as take care of a relative. As they stressed in HBR, managers tend to identify Availability with effort and commitment. “Our studies show that the commitment is valued almost more than productivity. In short, we seek to perceive that a worker is really committed, and that is what, in fact, we reward more than productivity,” declaredBuechel a Fortune If you take care of yourself, you don’t ascend. The experiment revealed that, in addition, 62% of managers considered that those employees who put limits between working time and staff were less likely to be promoted, despite recognizing that their productivity could be greater. A bias that too It was given on teleworking. As Eva Buechel explained, co -author of the study: “The same people who said that workers were going to be more productive also said they were going to be less promotable.” This bias reflects that, although the disconnection and rest improve health and employee performance can negatively affect the perception of commitment and professional opportunities since employees who respond outside your working hours or that their vacations skip are seen as people who strive more. The cost of not disconnecting. The pressure to always be available generates negative consequences. According to data from A studyMade by the Glassdoor Employment Portal, exhaustion reports increased by 32% year -on -year during the first quarter of 2025. Employees who claimed to feel exhausted have shot themselves above 50% if it was counted since 2019. “Even if a satisfied or high -performance employee can support a greater workload without impact on its productivity or in its satisfaction during a short period, that does not necessarily mean that it can do it indefinitely,” wrote Daniel Zhao, author of the Glassdoor report. Benefits of taking a break. A meta -analysisLed by Ryan Grant, a PhD student in Psychology at the University of Georgia, he found that the revitalizing effects during free time are actually 85% greater than what was suggested in different studies, and their benefits can be extended up to 43 days after the holidays. Grant points out that the disconnection capacity “was the only recovery activity that had a strong positive association with well -being, both during the holidays. This suggests that the more you disconnect yourself psychologically from work during your break, the better your vacation will be your vacation and the greater your benefits for well -being later.” The scientific evidence It corroborates Grant’s conclusions on the benefits in the mental health of employees who separate work time and leisure time. Disconnected by law. Countries like Spain and Australia have created a legal framework to guarantee the Right to digital disconnection Out of working hours. The regulations not only exempt employees from responding to any message or call of their work during their rest time, but penalize companies that carry out these practices. What the legislation cannot regulate is the perception that managers have of those workers who comply with the work schedule that appears in their contract.

The Rimac Nevera R has two curious records. It is the fastest electric in the world and, at the same time, nobody wants to buy it

by

He RIMAC Nevera r He has monopolized the attention of the whole world for his impressive speed and power figures. However, this electrical hyperdeportive, despite break speed recordshe has not managed to conquer the heart (or the wallet) of the wealthiest buyers. That produces the strange paradox that, while motor world fans celebrate the technological advances applied to one of the most brutal electrical hyperdeporters that have existed, the reality of their sales dazzles their track achievements. A world speed record that is not enough. The Rimac Nevera R has beaten the World Speed record For production electric cars, reaching an official brand of 431.45 km/h. However, the fridge R could not maintain Your domain in Nürburgringwhere it was overcome by the Xiaomi Su7 Ultrawhich became the Electric faster in rolling for the green hell of Nürburgring, despite being a superberlina and not a hyperdeportivo like the fridge R. Mate Rimac, founder of the Bugatti brand and CEO, acknowledged in a company statement that “Beating records is in our DNA, and we will not stop here.” However, according to The published by Bloombergdespite these achievements on the track the fridge R has not achieved the expected commercial impact. Why don’t Millionaires want the fridge r? One of the hypotheses that have considered Rimac is that the low demand can be related to the preference of high purchasing power for combustion hyperdeporters. According to collected CoachMate Rimac believed that “the market for electrical hyperdeporters is very limited. Most buyers in this segment still want the drama and emotion of an internal combustion engine.” This reluctance a embrace electrification In the hyper -sports segment it limits the potential market of the fridge R, however impressive their technical figures are. The Croatian brand acknowledges that “it is unlikely that we will manufacture another electric hypercoche in the short term”, reflecting the difficulty of convincing millionaires to change gasoline for electricity, even if it is 431.6 km/h. Only 40 units and record power. The RIMAC Nevera R is a limited edition based on the original fridge, but with an increased power in 200 hp with respect to the Original Neverareaching a total of 2,017 hp. As usual with the hypercoches, of the original fridge only 150 units will be manufactured, but in the case of the fridge R, its roll will be even lower, since it is a limited edition to 40 units, which underlines its exclusivity in the market of electrical hyperdeporters. The price of each unit is around 2.3 million euros more taxes, placing it at the top of the most expensive electric cars in the world. This combination of power and exclusivity has not been enough to convince the richest buyers, who seem to prefer other options. Porsche is worried about Rimac’s sales. In Porsche they are not satisfied with the sales figures of the refrigerator and motives are not missing. According to him annual report From Porsche, the German brand has 20% of Rimac’s shares, which makes it a part interested in the financial success of the Croatian company. “The profitability of our investments in Rimac depends on the commercial success of its models,” says Porsche report. The low sales level has generated a 46% collapse in the benefits up to 182 million euros. According to Autocar, in May 2024, the brand had only delivered 50 units of the refrigerator of the 150 that was going to manufacture. Before such a panorama, the additional 200 hp offered by the fridge R is not expected to be sufficient incentive for the millionaires to queue in the brand’s dealerships to take one. Maybe still Not the moment of electrical supercar. In Xataka | Bugatti has found a new reef: his clients are spent on average 500,000 euros on extras to customize his car Image | Rimac

The US already has the first salmon cultivated in the laboratory. It is a relief for wipes who ask for the time

by

The world is hungry for fish, but goes through areas. In Spain, Consumption is downhillso much that fishmongers want to reinvent themselves to serve our pets Before us. In other countries, such as China, That hunger is voraciousto the point that your folders They have been small And they are Going for those of Latin America. To avoid folding, there are those who investigate “alternative proteins”, And in the United States they have already developed the first salmon cultivated in the laboratory that is served in a restaurant. And with a series of advantages that does not really have salmon. Fish hunger. The forecasts They point out that the global aquatic food consumption will double by 2050 compared to the 2015 levels. That will imply that it will go from about 80 million tons annually to almost 155 million tons. The problem is that production must follow the rhythm. It is something promoted by population growth, the improvement of quality of life in certain countries and the development of aquaculture. As we say, China has a role in this story because it is not only the largest world consumer of fish, but it is also creating huge ships to raise new fish. And in Africa also An increase in demand is being seen. According to the FAOto maintain consumption until 2050, total production should increase by 22%, and is a capital challenge. That’s where the laboratory alternative becomes interesting. Cultivating salmon. Wildtype It is a company that has attracted to investors Like Jeff Bezos, Mandamás de Amazon, but also actors such as Leonardo DiCaprio or Robert Downey JR. Currently, they operate a factory in San Francisco and have just launched the ‘Saku’. This is cultivated salmon that is designed to eat when Sashimi stylewith a texture, flavor and ‘freshness’ comparable to really salmon. Here the key is to know how this salmon has been cultivated (it becomes weird to speak in those terms of a fish). The researchers extracted real salmon cells, specifically from salmon coho in their fry stage. In BIORREACTORS And using a patented “nutrient mixture”, cultivate those cells, combining the resulting cell mass with vegetable ingredients to replicate both the texture and the taste of traditional salmon. As they expose in The Washington Posta salmon can take about two years to mature, but in two weeks a 220 grams “fish” block can be created with the Wildtype method. And claim that it has a nutritional and omega-3 profile similar to that of wild salmon. One from Saku “NO OBJECTION”. And what do agencies that decide what enters, and what not, in circulation in the United States think? Well, they have no objections. ” Each country or region has a health entity that is the one that establishes a regulation that allows certain substances and products to be present in what we eat. They do not always agree, but if a product wants to enter a market, it must pass under the magnifying glass of that body. In the case of the United States, it is the FDA (Food and Medicines Administration of the United States) that, at the end of May, He gave permission to Wilkdtype so that your cultivated salmon is marketed. With that success, the cultivated salmon has already debuted in Kanna famous Haitian restaurant located in Portland, but it is expected that little by little it will arrive at more restaurants and shops in the form of ‘false’ packaging. Looking at the advantages. As with the coffee without coffeesalmon without salmon will allow maintaining the production of a very consumed food, but without continuing to measure in some wipes that agonize. But as important as sustainability, reduction of overfishing and habitat destruction which implies, is the issue of food security. This ‘Saku’ occurs in a production environment controlling, which minimizes exposure to pollutants, parasites and something that, unfortunately, is present in practically everything we eat, but above all the food from the sea: The microplastics. And another from Saku And the fishermen? When something that replaces something already established, the first question that comes to mind is what will happen to what moves to give way to the new. We have seen it from the Industrial Revolution, with AI and to Wimbledon with the Line judges being replaced by a computer. And, in this case, the question is whether something like this seeks to replace fishermen. Justin Kolceck is the co -founder of Wildtype and, in this article of the Washington Post, he comments that they do not seek to put fishermen outside the business or “eliminate the need for aquaculture. The amount of fish consumed is booming and the projections are so high that we will really need all the production we are doingin addition to the traditional and some more help in the world of plants to meet demand. For my part, I only have to add that in some Spanish supermarkets there is already salmon based on plants and oil and, although it reminds the taste of the animal, the texture does not look like. Maybe that Saku is the answer … Image | Lou Stejskal In Xataka | Until the 90s nobody in Japan ate sushi with raw salmon. Until a marketing campaign changed everything

A US Nuclear Submarine has just arrived in Iceland for the first time in history. That can only mean one thing: Giuk

by

When 2025 United States began, a word incessantly repeated: Greenland. There was no appearance of Trump where he did not slide that Washington was interested in getting the small nation, even for the bad. Behind, of course, There was much more that an occurrence, because the island is part of a Western strategic edge that he shares with the United Kingdom and Iceland. Interestingly, the first nuclear submarine in the US has just come to stay. First nuclear scale. Yes, by first time In history, a nuclear propulsion submarine in the United States has docked in Iceland. He USS Newport Newsa fast attack unit Los Angeles classarrived in Reykiavik in a movement that underlines the growing strategic importance of the Arctic in a context of Geopolitical tensions increasingly acute. The Icelandic government only began to allow the entry of nuclear submarines in its territorial waters in 2023and this inaugural visit is part of an increasingly narrow cooperation pattern with Washington and NATO. The American navy presented the event as A “decisive moment” which reaffirms its commitment to collective defense and maritime security of the Arctic, while American diplomats in Reykiavik stressed that the operation has been carried out in full Coordination with Icelandcountry that does not have its own naval forces and depends on the allied umbrella for protection. Giuk. It We count A few months ago. The geostrategic background of the event is closely linked to the call Giuk runner (Between Greenland, Iceland and the United Kingdom), a strip of key waters through which routinely submarines of the Russian north fleet, including the advanced yasen-m Cruise missile carriers. The location of Iceland makes the island a vital control point to follow these vessels before they are hidden in the vast Atlantic and represent a potential threat to the east coast of the United States. During the cold war, Iceland housed to the 57th Hunting Wing of the American Air Force at the Keflavik base, as well as maritime surveillance detachments With P-3 Orion aircraft. Currently, this surveillance persists with modern P-8a Poseidon and with NATO fighters that rotate to cover the Icelandic airspace. The Newport News stop adds to that renewed defense network, in a context where NATO has intensified protection of underwater infrastructure after alleged sabotage acts Russian In the Baltic which alerted about the vulnerability of vital cables and conduits. Sobs on board the submarine make guard while arriving in Reykjavík, Iceland And more. As We explainYes, let’s say Russia or China cross the corridor, its location would become extremely difficult, both because of the acoustic conditions of the underwater terrain and by oceanic vastness. Thus, from those hidden positions they could launch missile attacks against objectives in the east of the American continent. In fact and in response to this, the United States formed in 2021 the so -called Task Group Greyhounda specialized group of anti -submarine destroyers Designed to counteract This specific threat. The American navy itself warned at the time that the east coast of the country already It was not a safe shelterunderlining the urgency of establishing surveillance and defense points in key areas such as Greenland. The Russian answer. The truth is that Russia has proven to know very well the value of this corridor. In 2019, he organized its greatest naval exercise From the Cold War, sending at least ten submarines through the completely submerged Giuk gap, with the aim of Reach the Atlantic without being intercepted. According to Norwegian mediathe intention was clear: to prove the capacity of the West to detect movements of his fleet and demonstrate that he could project power to the US coast. These exercises also fulfill a fund growing territorial presence. A new stage. Beyond its symbolic value, the arrival of the Newport News represents an important operational step for the United States: to have a logistic support point for nuclear submarines in the Arctic without the need for move to Scotland or northern Norway. The ship, equipped with twelve vertical launch tubes for Tomahawk missiles and anti -submarine and anti -surface warfare systems, also provides surveillance and deterrence in a region where Russia has reinforced its naval presence and has increased its military activity near Finland. Icelandic Foreign Ministry itself recognized that these visits contribute to continuous and efficient underwater surveillance that also protects critical infrastructures submerged in Icelandic waters. Since 2023, six American submarines They had already briefly entered the island waters for partial crew rotations, but this is the first stop in port, product of bilateral regulations prepared with discretion and based on similar agreements with other Nordic countries. An emerging axis. The submarine scale is not an isolated case: in 2019, B-2 Spirit poachers They also used Iceland as an advanced base, which was a novelty for both aircraft and for the island. The ability to operate from austere locations has become a key principle of the American projection strategy. Iceland, who for decades played a secondary role after the end of the cold war, is repositioning as a central node in the defensive device of NATO in the north, especially in front of the resurgence of the Russian underwater threat. This scale, therefore, is not only a naval operation, but a silent but unequivocal statement of intentions: the United States contemplates the Arctic as a theater of strategic competence in full boom, already Iceland as its new bastion.
