Renfe aspired to win 5,000 million euros with an AVE in the US copying Japan. His government has just kill him

by

Unite the cities of Dallas and Fortworth with Houston. That is the project with which Renfe hoped to continue growing in his international projects. The construction of a high -speed line for just 386 kilometers that allows these cities to be connected in just 90 minutes. The project allows to connect the two most important Texas cities with a train that travels to 386 km/h, according to You can read on the Renfe website. The Spanish company has presented this project as Texas Advisor Central Railroadoffering their experience in “the stages of development, design and construction and in the commercial operation (operations, maintenance, promotion and sale of tickets)”, according to the company’s own words. Renfe went up to the train of this project in 2018 and his involvement grew in 2021 when he signed the contract to become an infrastructure operator. With this new high -speed line I expected to win more than 5,000 million euros from here to 2042, when the contract expired. However, the United States government has withdrawn all funds. A dead point project “I am pleased to announce that Fra and Amtrak agree that the financing of this project is a waste of taxpayers’ funds and a distraction of Amtrak’s main mission to improve their existing deficient services,” The statement indicates Sent by the United States Department of Transport. The words are from Sean Duffy, Secretary of Transportation of the country that has withdrawn the 63.9 million dollars of subsidy that the Federal Railway Administration (FR) dedicated to the high -speed railway corridor of Amtrak Texas, previously known as the Texas Central Railroad project. In the published information, Duffy emphasizes that the project was born with an exclusively private spirit but that with delays and unforeseen costs increased significantly. So much that they estimate that you can go to the 40,000 million dollars “What makes the construction unrealistic and a risky company for the taxpayer”, in words expressed in the statement. The high speed project to join these two cities re -enters the dead and is a setback for the Spanish company. They explain in Five days that Renfe became part of it in 2018, first with a job of Advice and Line Design. In 2021, The contract was extended and made the Spanish company a future operator of the same with which he hoped to win 5.3 billion euros before 2042. However, the issues With this high -speed line they had been accumulating long before. The creation of this line has its origin in 2009 under the company Lone Star High-Speed ​​Rail LLC. Three years later, the company changed its name to Texas Central Railway. After verifying that the costs were fired, it was accepted that public capital supported the project. In spite of everything, the calendar has breached again and again. Environmental and security permissions should have been achieved in 2020 but delays have been added to which the colon of the coronavirus crisis and an expropriation of land that follows in the courts have been added. In 2017, the United States government with Donald Trump to the head included the project as “a national transport infrastructure priority,” they point out in Five daysand with Joe Biden in command of the country State funds from the Infrastructure Plan were allocated To keep the project alive. Now, in Trump’s second term, the Department of Transportation has canceled it. Until now, the plan went to implement a small -scale replica of the famous rail system of Japanese high speed tokaido shinkansenoperated by Central Japan Railway Company (JRC). Thus, the train It could reach 386 km/h peak speed and join Dallas and Fortworth (separated by about 50 kilometers) with Houston in 90 minutes. You wanted to establish a regular service with a train every 30 minutes.

Miura 5 of Pld Space

by

After the flight of Isar Aospace flight and a sudden change of CEO in RFA, the Spanish company PLD Space cuts distances in The race to put in orbit The first European private rocket. From Miura 1 to Miura 5. Founded by the Ilicitanos Raúl Torres and Raúl Verdú in 2011, PLD Space successfully launched The suborbital rocket Miura 1 from Huelva In 2023. The 12.5 meter pitcher served as a test bench to validate many of the technologies that PLD Space has now been able to apply directly to his older brother, Miura 5. Miura 5 is A two -stage orbital rocket and 35.7 meters high Designed to put up to 540 kg in polar orbit or 1,080 kg in the low terrestrial orbit. Your heart is five trell-c engines of liquid oxygen and oxygen, internally developed with a total thrust of 950 kN. The second stage uses an optimized version for the emptiness of the same engine. First tests in Teruel. The new PLD Space headquarters is a 12,500 square meter factory located in Elche. It can produce up to six and 60 treprel-C per year. However, the engines’s trial center and the Spanish rocket is located at Teruel airport. At the end of 2024, PLD raised a 20 -meter test tower in its Teruel facilities to submit tanks and other structural components to pressure tests at cryogenic temperatures. In addition, he adapted the Miura 1 test banks to validate components of the new engines, and is building a new bank capable of trying three of these engines at the same time. With the height of a person, Treprel-C engines have the largest liquid propellant combustion chamber that has developed a commercial company with private capital in Europe. Worse funded, but growing. Unlike the German Isar Aerospace, which has a financing of 400 million euros, PLD Space has raised 170 million With the support of the aerospace belonging (40.5 million in the second phase), syndicated loans (31.2 million Santander, EBN and ICO), public financing (11 million co -confisses) and ESA contracts, Like the Boost program! to launch before 2027. PLD Space also has the client portfolio almost full. The Spanish company claims to have covered more than 80% of its launch holes up to 2027, which translates into an income forecast of 596 million euros. Just a few days ago, PLD closed an agreement With the D-AORIT space logistics company to launch its Ion Orbital Transfer vehicle and other satellites to equatorial orbits. In addition, they have exceeded 300 employees and grow at a rate of 15 hiring per month, especially in technical and business profiles. Two space ports. The main base of Miura 5 will be the European Space Puerto of Kouroou, in the French Guiana. PLD Space reached an agreement with the French Space Agency CNES for the construction of the complex. On the other hand, in February 2025 he announced his Second launch base In the Etlaq Space Puerto, in Oman. This movement will give PLD Space direct access to the Middle East market from 2027. The company also raises a third base to reach 30 launches a year from 2030. When will Miura 5 and its rivals fly? Although Raúl Torres, the PLD Space CEO, He opted money to Miura 5 would fly in 2025the inaugural flight of the rocket is scheduled for the first quarter of 2026. Miura 5 will not be alone, although the last months have been moved for some of the main rivals. Isar Aerospace made his Spectrum rocket take off from Andøyain Norway, on March 30, but joy lasted little: at 20-25 seconds, the rocket lost control, He turned around and activated his self -destruction systemfalling to the sea near the platform. There is still no new date for the second attempt. Rocket Factory Augsburg (RFA), another heavyweight based in Germany, suffered a capital reverse in August 2024: The explosion of your first stagewhich has delayed its first flight to not before the third quarter of 2025. Just a few days ago, Stefan Tweraser, signed in 2021 as CEO, It was replaced by Indulis Kalninsa veteran of the aerospace industry. Maiaspace, A spinoff of the French group Arianegroupit is also in the race, with the advantage of belonging to the company that has maintained the coheretes of Europe next to Avio for decades. The other two great competitors of PLD Space host in the United Kingdom: Orbex, with their little prime rocket (180 kg to orbit Heliosíncrona) plans its first flight by 2025. Skyorora and its Skyorra XL rocket (315 kg capacity) also point to this same year.

In 1953 the United States decided to put a naval base in Rota. Now the installation looks at your future with uncertainty

by

When Europe spoke weeks ago of rearme There were a series of news that attest to the situation. First it was Germany through the Almighty Rheinmetall and With Volkswagen In the “helping” equation, then even Spain with a component factory in the Basque Country. In France, a Cold War Plan to “diversify” your nuclear umbrella. And if none of these proposals went ahead, Europe would always have the Naval Rota base in Spain. Until now. Uncertainty at a key point. The story was told this morning The Financial Times. In the quiet coastal town of Rota, to the south of Spain, the imposing presence of American destroyers breaks the idyllic postcard. This old agricultural town houses today The naval base most important in the United States in Europe, the key piece of the antimile shield that protects the continent. It happens that something seems to have changed this part for a while. He had promised a sixth boat in 2022, but Donald Trump’s re -election has fired the alarms about an imminent American troops cutin line with its narrative that Europe must stop depending from Washington for your safety. In numbers, this “restlessness” reaches the close ones 84,000 deployed soldiers In at least 38 European bases, all inheritance of World War II, but whose continuity is now questioned. Broken, symbol and vulnerability. Rota’s base was the fruit of A signed pact In 1953 between Dwight Eisenhower and Franco. That agreement today is a complex of strategic dimensions that includes air track, three docks and the largest weapons and fuel installation of the pentagon in Europe. Its location, near the Strait of Gibraltar, makes it a fundamental node for Project military power towards the Mediterranean, North Africa and the Middle East. In addition, its official status as a Spanish naval installation “Joint use” It forces the United States to coordinate certain movements with Madrid, which adds a layer of complexity to its operation. However, the FT said that for many US military, broken is considered little less than A dream destination Due to its high quality of life and a local economy deeply influenced by the base: two thirds of the city’s economic activity depend on it, and Spanish companies such as Navantia maintain millionaire contracts With the United States Navy. The aircraft carrier of the Spanish Navy Dedal The Trump factor. But as we said, the idyllic postcard seems to be living an era of uncertainty with Trump’s re -election. The contradictory signals from Washington have sown restlessness. While Secretary of State Marco Rubio described as “hysteria” Rumors about possible cuts, Defense Secretary Pete Heghseth warned that American protection It would not be eternal. Worry. The concern is that, before any disagreement (here the fan is broad, from commercial reprisals, European support to Ukraine or the rejection of geopolitical proposals such as the Acquisition of Greenland), Trump can decide to drastically reduce military deployment in Europe, even unilaterally. The tycoon now He has shown disdain for the historical commitments of NATO and has frequently folvado the Scarce spending in defense of its European partners, being Spain One of the most lagging. In addition, President Pedro Sánchez has confronted Trump on various fronts, since his recent Posture about China until His sentence to the Israeli offensive in Gaza, which raises the political risk for the base of rota. Europe without shield. If we stick to numbers, Rota base currently houses 2,800 American soldiersincluding units at sea, and its fleet of destroyers (endowed with these systems to intercept ballistic missiles) represents a mobile capacity without equivalent in Europe. Although fixed pitchers from Poland and Romania could assume part of the Antimisile shield, the European Navy lacks A real alternative to the power of US ships parked in Spain. Hence NATO, although nominally owner of the system, depends largely on Military infrastructure of the United States for collective defense. The European strategy, for now, has consisted of gaining military independence gradually, but is still far from being able to fill the void that would leave an abrupt American replication. Again, That rearme acquires more importance. Alternatives: Morocco. In the face of the possibility of a break, The FT had that some voices suggest that the United States could transfer part of its operations To Moroccocountry that reinforced its link with the Trump administration by normalizing relations with Israel in 2020. With less politically compromised facilities and greater diplomatic harmony, Morocco would be outlined as a possible logistical replacement for Rota. Moreover, apparently, from The Foreign Policy Research Institute They warn that, if the Spanish government overestimates its strategic value or underestimate the level of irritation which can generate in Trump, the consequences could be immediate and deep. Uncertain future. So things, and although for now the base It continues to expand and receiving investments, the rumors of cuts fly over the installation. The American media commented that American residents in rota try Keep calm And, meanwhile, Europe observes with restlessness a situation that transcends local geopolitics and raises an existential dilemma for the continental defense itself. The transition to a greater self -sufficiency European defensive, now, it seems more pronounced than ever, but while that mature or becomes effective transformation, the shadow of an unexpected turn under Trump’s second presidency looms over the Cadiz coast. At stake, the key piece of the antimile shield that protects the old continent.

There are 2,400 Tesla Cybertruck without owner. Fix the failure is to sell them in a SO: Saudi Arabia

by

Tesla expected her cybertruck to become a success of sales. Clearly, he did not calculate well what was coming. The company is in an unknown crisis. When he had managed to settle as another company of vehicles, an unexpected events are complicating his numbers. A stranger. Tesla sold less cars in 2024 that in 2023. It is not uncommon for a company to face this situation but is unpublished for Elon Musk’s company that year after year had settled in sustained growth. Although he did everything possible to improve his numbers at the end of the year, the accounts did not finish leaving. Despite this, investors pointed to an optimistic future. Despite the rejection of some of them, they had seen the Musk bet for autonomous driving And, with Donald Trump in power, the prospects were good enough for the shares to walk towards the 500 euros of value. A Batacazo. But 2025 is being a bad year for the company. Before the end of the year, investors began Adjust action prices. Then came the confirmation that Tesla did not improve numbers of the previous year. And month after month The sales of their cars have been weighed by the renewal of Tesla Model and … and we do not know to what extent because of political opinions and behavior of Elon Musk. The truth is that the company has crashed in Europe. The Tesla Model and, which was The best -selling car in the worldis missing at the moment until the arrival of his renewal. It remains to be seen how much traction it now has that the competition squeezes and seems discarded a Tesla “cheap” of $ 25,000. With name and surname. If a car is being a failure that is the Tesla Cybertruck. The company’s pick-up promised to be a success. It was supposed to accumulated hundreds of thousands of reservations And it did not seem to import that it arrived with a very marked premium and, to top it off, a reduced autonomy. At times, the car was a sales missile and became the best -selling luxury model of Tesla. But, little by little, the globe was punctuing. The multiple arrived Review callsthe videos in which He joked with his offroad capabilities and one Foundation series that seemed impossible to sell. To the point of putting the same car on the street for thousands of dollars less Thanks to remove some sheets. They are not sold. We already explained Why Tesla could have made Cybertruck a special model in its range, well built (to which the plates did not fall), produce it under minimum, generate expectation and risk very little with its proposal. However, the company wanted to believe that its gigantic Cybertruck could be a mass car. And everything indicates that their calculations have been completely wrong. In Motorpasion They collect that the company has an average 30 -day stock available. It could deliver up to 2,400 vehicles that are valued at a price of about 200 million dollars. Right now, they are completely standing waiting for a buyer. Of course, it seems that the production of 1,300 weekly units It is being more a problem than an attractive figure. Looking for solutions. Overdimensizing the demand of a car can be a serious problem for a brand. Having too stock stands out the product and generates serious cost problems when storing vehicles. In addition, he suggests that too much money has been invested in a assembly line that is not profitable. That same problem has had, for example, Stellantis that did not measure (or Tavares did not want to measure) Well your audience in the United States. That caused an excess of stock in some concessionaires that practically gave the fiat 500ethe electrical version of the utility. The decision made by Tesla is also the most obvious: to start selling its cheapest options. The company has opened a new line offering the most modest versions of the Cybertruck. It is the so -called Long Range, with greater autonomy but less benefits and a simpler suspension (springs instead of pneumatic suspension). Saudi Arabia. The other way to open market is Sell ​​your cars in Saudi Arabia. While the company eliminated the Chinese market the Tesla Model X and Model S (almost testimonial there) as a result of the increase in tariffs between the two countries, the company looks at the Middle East. The country has launched a project to fill its cargo points, as part of the plan for converts as a nation for 2030. Aware of the money available for its potential customers, Tesla has not hesitated to offer all its range in the Arab country. Actually, it is a maneuver that makes sense. Tesla can allow you to distribute your cars there and try to open a new market. Perhaps it will not be the one that generates the greatest sales volume but it is likely that you can sell your most expensive and, therefore, profitable cars there. A Tesla Cybertruck can find a very nutritious market in Saudi Arabia. Photo | Tesla and Abdulrhman Alkhnaifer In Xataka | The owners of a Tesla Cybertruck “packed” it with solar panels for $ 10,000.

Openai’s hypothetical social network does not want to connect people. Want your data to train your AI

by

In Openai they do not conform to being absolute referents in the segment of artificial intelligence. The last rumors point to that They intend to create a social network that would go beyond Chatgpt. The reason, eye, is not to compete with Facebook, Instagram or X. At least, not directly. Social network = data to feed the AIThe movement responds without a doubt to that voracious hunger of new data that the AI ​​models have and that allows them to improve and polish their behavior in different scenarios. A social network would allow Openai to use all those data entered by users to train their models. X already discovered that trend. The Fusion between X and XAI It was already a clear demonstration of that strategy: suddenly I had a perfect system to train its AI, Grok model, with all the posts of X users. And goal, of course, too. Goal takes time doing the same With Facebook and Instagram – although The EU forced her to slightly change your plans – and also collect data when we use ai target at whatsapp, Although you can avoid it. All with the same goal: to have “fresh food” for its artificial intelligence models. A social network to share images. Apparently the prototype that is already developed focuses on Chatgpt’s ability to generate images. It would therefore be a social network more similar to an instagram full of images generated by AI, from which we imagine that users would be generated. Altman already warned. The funny thing is that the rumor occurs weeks after Sam Altman himself, CEO of OpenAi, jokes with that possibility. When the news appeared that Meta was preparing an independent app for goal AI, Altman replied saying “ok, perfect, perhaps we make a social app.” This does not connect people. Perhaps they already had the project and it was not a joke, but although Altman pointed out that that could allow “revenge” of Facebook, the intentions would not be those of competing with Facebook when connecting people – the original purpose of that social network, at least – but that of collecting more and more data for their AI, which is what they have also ended up doing social networks. And the AGI for when. The problem of this theoretical project is that it would be partly a distraction for Openai. It would certainly allow for more data for the training of its AI models, but it is not clear that the scaling is the right path for the ultimate end of OpenAi: get a general artificial intelligence or agi. Too many parallel projects. Altman is famous for generate excessive expectations about the AGI. However, this challenge is tarnished by their last releases, especially in the case of GPT-4.5. The company seems to be somewhat scattered with gigantic projects like Stargatethe development of Your own chips o The mysterious hardware project In collaboration with Jony Ive. Too many apples in the basket? We will see. Image | Xataka with chatgpt In Xataka | Chatgpt is already the most downloaded app in the world.

You can no longer sell your chip for the most successful in China

by

The commitment reached Jensen Huang, the general director of Nvidia, and Donald Trump At the end of last week In the restaurant of the Mar-A-Lago Tourist Complex of Palm Beach (Florida) It was a mirage. Wet paper During the last weeks several filters anticipated that the Department of Commerce, which under Trump’s mandate is being led by Howard Lutnick, intended to prevent the chip for artificial intelligence (AI) NVIDIA H20 I continue to arrive in China. At the current situation for the company directed by Jensen Huang this GPU is very important. In fact, her engineers designed her to have a chip for the people who could deliver to her Chinese clients when US sanctions They prohibited Nvidia for sale in the country led by Xi Jinping of the GPU A800 and H800as well as graphics cards with chip GeForce RTX 4090. Previously the Department of Commerce had also radically restricted the sale in China of the GPUs A100 and H100the most advanced of Nvidia at that time. Nvidia’s success in China has the days counted The reception they have given to the GPU H20 The Chinese clients of Nvidia has been very good despite the fact that the capabilities of this chip are clearly lower than those of the other proposals for the this company. In fact, initially the Department of Commerce allowed its sale in China because this integrated circuit met the restrictions it had imposed. And despite its limitations its sales in China 50% quarter to quarter have grown Since he arrived in this market in mid -2024. The US Department of Commerce has imposed export restrictions on China from the GPU H20 Despite all this era of bonanza for Nvidia in China is about to finish. And finally the leaks have been fulfilled: the US Department of Commerce It has imposed restrictions to the export to China of the H20 GPU, and this in practice means that this chip presumably It will not reach Chinese clients in Nvidia. During the dinner I have mentioned in the first lines of this article Jensen Huang presumably committed to Donald Trump to invest more money in data centers for the US. In return, Nvidia could continue selling its H20 GPU in China. After all, this is the chip that currently supports its business in this Asian country. But This pact has faded. And the company led by Jensen Huang is already paying it. His shares have fallen 6% and Nvidia has announced that this prohibition will cause a hole in its accounts of 5.5 billion dollars due to the commitments linked to the H20 GPU that the reserves of this chip had already acquired that it will finally not be satisfied. Among the Chinese clients who have bought large amounts of this GPU, and who presumably planned to continue doing it, are Tencent, Alibaba or Bytedance.

The F-35 and the US ballistic missiles need the key component of a magnet. The problem is that it was “Made in China”

by

Finally, China carried out what the global industry feared: blocking the export of rare earths more valuable. In this way, without more, it sounds tremendous, although surely many will wonder how far the scope of the veto really comes, or which supply chain will be affected in the short term with Beijing’s decision. There are many sectors against the strings, but there is an especially delicate one for Washington: Defense. If everything remains the same, you have a few months left for your F-35 or ballistic missiles to have a serious problem. The Achilles heel. I told it The New York Times A few hours ago. China’s decision to impose restrictions on the export of critical minerals and, especially, of certain rare earth magnets, represents a direct warning to the national security of the United States, whose military capacities They depend largely of these resources. Which is it? We talk about Combat fighters of the Air Force, like F-35of guided ballistic missiles of the army or electric drones of the Marines, where these magnets (made with elements such as neodymium, disposium or ititrium) are essential for the operation of motors, guidance mechanisms or emergency systems. If, for example, a ballistic missile does not include the component of these magnets, it would be impossible for their goal to reach. The background problem. That 90 % of these components are produces in Chinaand six of the key metals that compose them are only refined there, which gives Beijing a powerful pressure tool. This maneuver, considered a “warning shot” by An official From the Air Force, it could easily climb towards fees, tariffs or even a total prohibition, generating an immediate impact on the costs and availability of American military technologies. A vulnerable chain. It We have counted other times. Rare earth (a set of 17 elements) is not that they are scarce in the strict sense, but its processing is expensive (and polluting), which is why China managed to dominate both its extraction and the associated refining and manufacturing. This supremacy has allowed him control much of the final cost of the modern American weapons, including those poachers, submarines, war ships, tanks, missiles and laser systems. To get an idea, only one F-35 contains around 400 kg of rare earth materialswhile some submarines They exceed 4,000 kg. Although the American defense industry and the pentagon have accumulated strategic reserves of these elements, analysts warn that these collections would barely reach to cover a few months of production and maintenance, not even years. From there, as we recently counted, that Washington has noticed the Pacific fund. Future warnings. Actually, the United States already knew about this unit and what could happen for a few years. It happened with an emblematic case, the call “F-35 “magnet debacle”when in 2022 the Department of Defense temporarily suspended the delivery of these aircraft after discovering that a component contained a Alloy manufactured in Chinacontravening defense acquisition standards. Although at that time it was considered that the material did not represent a direct threat, the incident highlighted the depth of the US dependence. Now, with the obligation that Chinese exporters Request special permits Before sending rare earth to the United States, experts anticipate a price increase that will affect the entire industrial defense base. Yes, the MINTAIN PASS MINA In California it has resumed operations, but its production is far from competing with Chinese capacity. Historical precedents. Looking back, history offers examples of how the United States must have adapted to interruptions of the supply of strategic materials in times of war. For example, now It happened with the bauxite During World War II, when Germany sank allied charges that transported it from Surinam. So Washington turned to Domestic reserves in Arkansas to guarantee the production of airplanes. Today, The Times told that there are already voices from the sector, such as American Enterprise Institutewhich insist that current reserves are not enough to sustain the military-industrial complex in the face of a long interruption of the Chinese supply. Despite the initiatives of Trump and Biden governments to Reactivate national production Of critical minerals, the industry remains highly vulnerable to Beijing’s decisions. A critical dilemma. No doubt, there is a much broader background with what happened in the commercial war. Chinese control over rare earth supply not only implies logistic or economic vulnerability: it represents A geostrategic challenge First order for the technological supremacy of which the United States has always presumed in the military. The recent Chinese measure does not close trade routes completely, but it makes it clear that Beijin possesses A pressure lever Formidable about the American defense industry. Faced with this, analysts agree that Washington must accelerate efforts to diversify their sources of supply, recover internal industrial capabilities and ensure the resilience of a supply chain that supports a good part of its global power. Otherwise, the next crisis may not limit yourself to that “warning shot”, but to become a direct blow to the technological backbone of the National Defense.

Low salt diets were our ally to control blood pressure. We had been overlooking the importance of banana

by

Sodium and potassium are two key elements for the functioning of our body, one sometimes interconnected to the point of serving one as a counterweight of the other. The excess sodium that we associate with high blood pressure leads many to control their salt consumption. On the other hand, if there is a food that we associate with potassium this is banana. Although not the only remarkable one. Less salt … or more bananas. A study based on mathematical models He has found Tests that increasing potassium consumption can be even more effective than reducing sodium consumption when our goal is to regulate our blood pressure. This can help us increase the dietary options of people at risk of cardiovascular diseases. “Usually, when we have high blood pressure, we are recommended to eat less salt,” Explain in a press release Anita Layton, co -author of the study. “Our research suggests that adding more foods rich in potassium to your diet, such as bananas or broccoli, can have a greater positive impact on your blood pressure than just cut the sodium.” Electrolytes Both sodium and potassium function and electrolytes In our body, that is, substances that help our body conduct electrical signals, but that also fulfill other functions such as regulating the amount of water in our body or the level of acidity in the blood. Calcium, magnesium or phosphorus are other elements that enter this category. The sodium Specifically, it plays an important role in maintaining the volume of the blood fluid under control. Under normal conditions, if our body detects an excess of sodium or an excess volume in the extracellular medium, it reacts excreting sodium to return to normal. The lack of potassium is has related with greater difficulty in controlling the risks derived from sodium in our body. A mathematical model. The connection is well described in the scientific literature but the complexity of the biological mechanisms involved makes it difficult to estimate the magnitude of this connection between sodium, potassium and blood pressure. To estimate it, a team of researchers from the University of Waterloo, in Canada, has created a mathematical model that allows you to quantify this connection. The new model managed to identify how the potassium to sodium ratio consumed affects the body. The model takes into account aspects that affect this relationship such as sex or age. The team observed, for example, that, although men are more easily in an increase in blood pressure, they also respond to a greater extent to the increase in the proportion between potassium and sodium. The details of the study were published In an article In the magazine American Journal of Physiology-Renal Physiology. Evolutionary question. As explained by the team responsible for the study, evolution has been able to have a great impact on how these elements affect us. They point out that, during the recent evolutionary history of the human being, the presence of fruits and vegetables in our diet has been high, so it is natural that the regulatory systems of our body depend in such a degree of nutrients that these give us. Contemporary Western diets are, however high in sodium and low potassium. This could explain, they point out, why blood pressure problems are so prevalent in industrialized countries. Not only bananas. We usually associate potassium to bananas but these are not the only foods that this nutrient contributes. Among the foods that They stand out for their contribution in potassium They are vegetables such as spinach, tomatoes, avocados and brocoli; legumes such as beans, lentils and soy; The potatoes. Among the products of animal origin are some dairy products, and fish such as phatan, salmon and Verdel. In Xataka | Banana must die (and only science can resurrect it) Image | Pixabay

This cleaning device seems a genius. A removable vacuum robot that is also used as a vertical vacuum cleaner

by

From time to time we find the most curious concepts in Tel Mundo de Technology. One of the ones who have recently interested me is that of EUFY E20an anker cleaning device with which we can have both a vertical vacuum cleaner (or without cable) as a Robot vacuum cleaner. All this in a single removable device. * Some price may have changed from the last review A cleaning device two in one The EUFY E20 is a removable cleaning device whose main claim is to have two devices, an aspiring robot and a vertical vacuum cleaner. To do this, The vertical vacuum base is introduced into the vacuum robotthus allowing choosing the type of cleaning we want to have at home. In addition, it can also be used as a hand vacuum cleaner. If we use it as a hand vacuum, it can reach a maximum suction power of 30,000 pa; On the other hand, if we use it as a vacuum robot that maximum low figure up to 8,000 pa. What we do have in both cases is a Five Stage Filtration That, as the brand mentions, can capture 99.97% of the particles of less than 0.3 microns. The Anker device, in addition, comes with a load base to use it with the aspiring robot, or with the vertical and hand vacuum cleaner to empty dirt and recharge the battery. Includes Navigation system with triple laser precision; That is, it includes three lasers placed at the top, front and side to dodge obstacles easily. This base also includes a three -liter motor system. Without a doubt, personally this device has seemed very curious.
