spend 500 million in magnets

Apple has been the objective of Threats and criticism of Donald Trump from the beginning of the tariff crisis. The president of the United States has recently demanded to manufacture the iPhone in the country or pay a 25%tariff. Not only asks to leave China, Nor does India workwhat was it The great alternative. In the absence that from Cupertino they inform about structural changes, Apple has announced An investment of 500 million dollars in MP Materials, a snow -based company that, according to the company, is the only integrated producer of Rare earth of the country. Magnets, fuck (Jesse Pinkman said). Manufacturing the iPhone in the United States is unfeasible for Apple if you want to avoid one of 2,300 dollarsbut the company will invest in the local economy as they ask from the government. And the plan, for the moment and in part, passes through magnets. Specifically, neodymium magnets from rare earths manufactured in the country, and developed in Fort Worth, Texas. The magnets They are essential on the iPhone and in a lot of modern electronics: key load component by MagsafeThey are also crucial in microphones and speakers. The supply of the first rare earth magnets will begin in 2027. A larger plan. The 500 million dollars are more than an acquisition of materials. Apple and MP Materials have announced investment in the Texas plant, but also the construction of a new Mountain Pass recycling plant, California. In it they will reprocess recycled materials, as old components of used devices, which they will use in Apple products. However, the announcement not only remains in them: they will distribute magnets all over the world before the growing demand of rare earth magnets, in the electronics sector, but also in motor, aeronautics and military. The 500 million are framed within a much larger investment already announced by Apple in full tariff threat: 500,000 million dollars Over the next few years, with which they seek to build an AI servers in Houston, dated 2026, and an industrial training center in Detroit. Washington wink is clear. The Apple statement justifies the need to make this investment in a local company, but in the background is the fact of demonstrating to the federal government that they are prioritizing the national economy. Tim Cook mentioned that “American innovation promotes everything we do in Apple, and we are proud to deepen our investment in the US economy.” In addition, it also responds to Trump’s objective to create national technological employment: “The increase in production will generate dozens of new jobs in advanced manufacturing and research and development.” Now they do not mention complete figures, but the commitment of the 500,000 million promised to create 20,000 jobs. Own interests. Achieving a local supply, Apple also gains autonomy against China, authentic world dominator of rare earths: controls 70% of production and 90% of its processing. Trump’s threats turned against the country’s technology, because the Asian country Blocked the export of its most valuable rare earths. Fighting the great limitations of the country. Tim cook has said in the past that They cannot manufacture in the United Statesamong other things, due to lack of industrial knowledge. In that sense, the statement affirms that companies “will provide extensive training to develop the workforce, creating a completely new group of talent and experience of USA. In the manufacture of magnets.” By him Liberty PhoneWe know that achieving a 100 % American smartphone is tremendously complicated. His CEO said that “but there are some pieces that simply do not have supply chain,” so they will have to continue working to improve availability. The ironic is that not even the T1 of Trump Mobile will achieve be manufactured in the country. Image | Xataka and Pixabay In Xataka | The loss of the Broadcom chips factory is a malazo for Spain.

end to Ottawa’s treaty

At the end of April an exclusive of the Wall Street Journal Through satellite data showed a series of strategic movements of the Russian army on border enclaves. A few days before, The New York Times told how Finland I was preparing For an eventual war. Then it was the Baltic countries that began to surround Russia With 600 bunkers. Now all these countries have taken an unprecedented step. A shadow of the past. For decades, the Antipersone mines They marked the borders of the Soviet block, not as much as a Effective military defensebut as a brutal means of avoiding the flight of its citizens to the West. After the collapse of the USSR, the international community embarked on a complex and laborious demining campaign that culminated with the firm From the Ottawa treaty In 1997, backed by more than 160 countries. It happens that this legacy of humanitarian disarmament, which seemed sealed forever, now It is cracking. Following the Russian invasion of Ukraine, five European countries (Poland, Finland, Lithuania, Latvia and Estonia) have decided to initiate the legal process for leave the treatythus reopening the possibility of the systematic use of antipersone mines on European soil. Military pragmatism. The decision does not imply An immediate placement of mines on its borders, but it does mark a change of drastic approach and loaded with implications. For years, modern military doctrines minimized the tactical value of these weapons in conventional conflicts, underlining their indiscriminate character and scarce utility against armored units. However, the war in Ukraine has altered that reasoning: the extensive mines fields placed by Russia They were one of the decisive factors in the containment of the Ukrainian counteroffensive. Although they do not stop an mechanized division alone, they force the adversary to slow down their progress, channel their movements and spend valuable resources in cleaning operations, thus offering an asymmetric defensive advantage that many now see how inalienable. Italian antipersone mine Valmara 69 Legal and moral consequences. The Ottawa treaty was more than a military pact signed by more than 160 countries (important: without Russia, China and the United States): it represented A moral milestone In the history of humanitarian law. Its success allowed to reduce the number of victims by mines of more than 20,000 a year In the nineties about 3,500 today. The output of several countries Europeans not only weakens the treaty in practical terms, but undergoes legal architecture that since the end of the Cold War has sought to humanize conflicts. For many activists, Like Mary Wareham of Human Rights Watch, this withdrawal represents A dangerous crack in a consensus that also protects against chemical, biological and nuclear weapons. In his words, once the idea of abandoning international agreements gains legitimacy, it is difficult to stop The domino effect. What is at stake is not only a weapon, but the very principle that there are limits in war, he clarifies. Blow to the heart of Europe. The pressure on governments has been intense and transverse. In Finland, whose parliament voted for a large majority in favor of leave the treatyEven legislators contrary to the mines recognize that fear of a Russian invasion has altered national security priorities. The 1,300 kilometers terrestrial border with Russia, together with a story marked by wars With Moscow, it has generated a particular sensitivity that has given wings to proposals that just five years ago would have been unthinkable. The political trigger, however, Lithuania winewhere the then Minister of Defense, after visiting Ukraine, said that the prohibition of the mines was hindering the defense in front of Russia. From there, the idea spread among the most exposed allies geographically. Only Norway, among countries with direct border with Russia, has reiterated Your firm commitment With the treaty. The past as a warning. Ukraine, signer of the treaty in 2006I had kept more than three million mines. Frustration after the partial failure of his counteroffensive, together with Mass use of mines On the part of Russia, he led the Zelensky government to reconsider its position. In fact, the president announced this month formally Treaty outputarguing that an existential threat could not be fought with a hand tied by treaties that Moscow never signed or respected. The United States, although it is not part of the treaty, had maintained restrictions on the use of mines, but partially lifted them for supply to Ukraine. This has marked a tacit break with decades of diplomatic efforts and disarmament. For many, like British Paul Heslop (UN expert in demining), what we are witnessing is a betrayal to the memory of those who fought (and died) for eradicating these weapons.

Google announces its hardware event

Google has announced the date of its annual hardware event. The ‘Made By Google 2025’ will take place next Wednesday, August 20. The company thus confirms the change of calendar last year, when they left behind its traditional autumn event to move it to summer, a less congested time. What do we expect from Made by Google With the Google Pixel 9a Already in our hands, this year we wait for a fairly loaded Google event, because the company that runs Losco Pichai has been expanding its family until they currently count on the market with four variants of the Google Pixel, smart watches and the Pixel Buds headphones. This is what the leaks have advanced for the event: The Pixel will be the main protagonists of the event again, and after brand new design last year, this course is expected aesthetic continuism. The great novelty according to what we know will be that the new processor G5 tensioner I would be manufactured by TSMC After years with Samsung. This year, having advanced Android 16the Pixel will have the latest version installed at the time of launch. Even more relevant than the change in production would be the change in design, then A report It pointed to the South Korean company will no longer be involved in the design of the chip. That case draws A Pixel 10 Much more ‘Made By Google’and we will have to see what it is in practice at the level of performance and efficiency, where pixel They are lagging behind Regarding Apple, Mediatek or Qualcomm proposals. How to follow the event On August 20 Google will broadcast the event in Direct on YouTubeand in Xataka we will have all the news that it presents. This is the schedule announced for Spain and Latin America: Spain: 19 hours Mexico (CDMX): 12 noon Colombia: 12 noon Argentina / Uruguay / Chile: 14 hours Venezuela: 13 hours.

Madrid has the radar that most fine in Spain. We already know its location and where we have to be more careful this summer

3,440,655 speeding fines. Spain closed 2024 with a 4% increase in the number of sanctions for this reason. Associated European motorists (AEA) has carried out its annual report with DGT data to point to us which are the 50 radars that most fine in our country. This increase in the number of fines cannot be understood without the fact that there are more radars that fine in our country. Specifically, in Spain there are almost 3,400 controllers of speed that monitor that we do not exceed the maximum limits allowed. And those must add mobile radars and famous pegasus that watch from the air. In addition, we remember that in the AEA numbers of this report the fines imposed in the Basque Country or Catalonia are not collected, where traffic skills are transferred. The radar that is most fine in Madrid Given all this, AEA points out that the radar that most fine in Spain is at kilometer 20 of the M-40, the famous Circunvalación de Madrid. The cinemometer repeats in the first place but, perhaps because it is an old acquaintance, it has reduced its volume of complaints by 36%. In total, this controller has issued 74,873 sanctions for speeding, far from the 118,392 fines that it registered in 2023. The radar is not only in the Community of Madrid, since six others are part of the 50 most “multones” radars in Spain, being the province where the most controllers add up in this list. These are located in the following locations: Road M-40 PK 52: 33,057 sanctions. Road A-4 PK 13: 18,263 sanctions. Road A-2 PK 15: 15,713 sanctions. Road A-5 PK 12: 14,147 sanctions. Road A-4 PK 12: 13,722 sanctions. Road A-3 PK 48: 11,568 sanctions. What are the most fine radars? Although Madrid has the most fine of Spain and another six more radars appear in the list, Andalusia is the autonomous community that adds the most speed controllers to the list. In fact, according to AEA data, almost one in three fines processed in Spain have an Andalusian radar origin. In total, in 2024 they added 959,592 complaints, which represents 27.8% of the activity in the country, accumulating up to 14 cinemometers among those who most fine in our country. If we analyze by provinces, Malaga and Seville, with five and four radars among the 50 that most sanction in Spain are the two provinces (after Madrid) in which the most radars are located. As to Volume of complaints And despite the fact that Madrid has the radar that most sanctions, Castilla y León with 413,343 sanctions is the second autonomous community in which it is most sanctioned. And it is followed by the Valencian Community, with 366,360 complaints. As for the radars that most fine in Spain, these are the 10 that sanction: Autonomous Community Province Via PK Number of fines Community of Madrid Madrid M-40 20 74873 Andalusia Malaga A-7 968 67502 Navarre Navarre A-15 127 60878 Andalusia Seville A-381 74 54835 Andalusia Malaga A-45 128 49378 Balears (Illes) Balears (Illes) EI-600 9 39202 Andalusia Seville A-92 83 37616 Andalusia Malaga A-7 978 33358 Andalusia Malaga MA-20 10 33061 Community of Madrid Madrid M-40 52 33057 Photo | DGT In Xataka | How to know all the official locations of the DGT radars

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

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.

According to Downdetector dataa platform that includes user reports on the operation of online services, the failures began before 1:00 p.m. on Wednesday, but were shot from 23:00. At that time, the volume of reports increased significantly worldwide. 21 Instagram tricks – Tutorial with all secrets! The data offered by the service helps to better understand what is happening: 61% of the incidents have to do with the OPP operation21% with server connection errors, and 17% with problems logging. One of the clearest tracks than is happening, as it usually happens, in X (formerly Twitter). Several users have complained that storiesalthough apparently they work, they are not showing information on display or scope statistics. This is not a minor detail, especially for commercial accounts or content creators that depend on these data to measure the impact of their campaigns. But it also affects regular users, many of whom review who has seen their stories as part of their daily use of the platform. At the moment, Meta has not offered any official explanation. It is unknown what the failure is causingif they are working to solve it or when the service will return to normal.

This marriage traveled four hours to an idyllic destination they had seen on Facebook. Upon arrival they discovered that it did not exist: it was ia

It has happened to us to be sailing on Instagram or Tiktok and that a video of a tourist destination that leaves us with an open mouth comes out. Tale landscapes, dream cities and incredible attractions. Is what happened to him To this marriage of Malaysia. They saw a video on Facebook where an impressive cable car in Perak came out, just four hours where they lived. Without thinking, they took the car and traveled more than 300 kilometers to destination only to discover that they had just fallen into a hoax. The video. It appeared in networks at the end of June this year and, although it has already been erased, it can continue to be seen in This link. In it, you can see a reporter interviewing tourists who are visiting the place. It is an impressive cable car that makes a tour of forests, rivers and has all kinds of attractions around it. In the video the location of the place is detailed: Kuak Hulu, in Perak, Malasia. The visit. Although the resolution is not very good, the video is quite realistic, but we already know that nothing that appears in it exists. We also know that at least two people believed it was real and traveled for four hours by car to go to know the place. The story became public when an employee of a nearby hotel told In your Threads profile that he had just hallucinated: a couple asked him about a cable car he had ever heard. “There is not much to do here, it’s very quiet,” he said. A hoax. The couple’s reaction was to insist on seeing the place, thinking that he was spending some joke. Then they went on to confusion. Upon realizing that the site did not exist, the woman wanted to “denounce the journalist who comes out in the video.” Finally they understood that nothing they had seen was real, nor the journalist, and left the place ashamed. The generational gap. We do not know the exact age of this couple, but according to the hotel employee, they were older. The lack of digital knowledge by many older people is a problem, from something as everyday as make efforts with the bank until Recognize what is AI and what is not. Some platforms like Instagram tag Made with AI, but is a small “created with AI” enough for people with less digital experience to detect it? With cases like this it seems quite clear that it is not enough. The garbage. We have spoken on several occasions about the ‘ai slop’ or the garbage that has flooded the networks; from Very unpleasant videos that want to break the algorithmsuntil fake crochet patterns that are sold as real. The garbage is flooding everything, Even ASMR videos What did you see before going to sleep are. Much of this content is clearly AI, but with the arrival of tools as I see 3 It becomes very difficult to distinguish the reality of AI. And this has done nothing but start.

The answer was on the other side of the Pacific, in Japan

It is not enough to promise that a plane is less noisy. You have to prove it. That is what NASA proposed with its X-59an experimental plane that wants to change The future of supersonic flight. To achieve this, I needed data. Very precise data. And therefore, although the project is American, a key part of validation was carried out in Japan, in one of the supersonic reference facilities in Asia. The X-59 Quesst is an experimental plane created with a very specific mission: demonstrate that it can be flown at supersonic speed without that meaning a rumble on land. What NASA wants to eliminate is not speed, but noise. The classic boom Sonic, that dry burst that rumbles when an plane overcomes the sound barrier, remains one of the great obstacles for supersonic flight Return to commercial aviation. The X-59, on the other hand, promises something different: A slight THUMPbarely noticeable from the ground, thanks to a design that controls – and disintegrates – the shock waves before they are based on an acoustic explosion. But it is not enough to design a stylized and elongated form. It is not enough to simulate it on a computer or anticipate its behavior with computational models. What defines X-59 is not only its silhouette, but the sonic firm that projects When flies to Mach 1.4. That firm, that acoustic footprint should be measured with surgical precision. And that’s where Japan enters the scene. NASA did not do everything at home: key part of the validation was done in Japan Although the epicenter of the project is located in Palmdale, California, under the direction of Lockheed Martin Skunk Works, part of its most delicate validation was carried out on the other side of the planet. Instead of limiting yourself to try your model in your own facilities, NASA decided to repeat the trials In a supersonic wind tunnel of the Japanese space agency (Jaxa), located in Chofu, Tokyo. There, researchers from both agencies They exposed a plane modelreduced to 1.62 % of its actual size – 50 centimeters from tip to tail – to conditions that simulated its cruise speed. The objective was clear: to verify how the air flowed around the aircraft and, above all, register with the highest possible precision level its sonic signature. Japan’s choice was not symbolic. As NASA itself detailsthis was the third round of wind tunnel tests carried out with that same model: one was made in Ohio, at the Glenn Research Center; another, in the same Jaxa tunnel years before; And the latter, also in Chofu, was raised as part of a cross validation strategy. Even if you put the model in another wind tunnel, a slightly different version of the data is obtained, that is something good, Melissa Carter explainedresponsible for the NASA Supersonic project. “By using the same model in both tunnels, we can increase the certainty of the data and our understanding of the X-59 design.” The measurement of the pressure profile – the acoustic footprint that leaves the plane when it breaks the sound barrier – does not admit errors. And the best way to reduce any margin of uncertainty is to verify that, under different conditions And with independent instrumentation, the results remain consistent. That is what allows collaboration with Jaxa. As part of an agreement signed in 2020both agencies pledged to share data, compare methodologies and repeat essays in both countries, thus reinforcing the solidity of the entire experiment. The wind tunnel where the tests were performed is not any. It is a supersonic installation operated by Jaxa, with a section of just over a meter by one meter. Although their dimensions may seem modest, they are ideal for working with very small models such as X-59. In it, the air flow can reach sufficient speeds to simulate real flight conditions, which is just what NASA engineers were looking for. For Jaxa, the opportunity was also key. The Japanese agency has been developing its own “silent” supersonic flight program for years, With projects like Sky Frontier. Sharing information with NASA allows you refine your own designs, Learn from different approaches and validate your simulation tools with real data. In return, it offers experience, equipment and infrastructure that complement those of the United States. Images | NASA (1, 2, 3) | Roméo A.

They show how the magnetic field is invested

NASA has gotten into the wolf’s mouth, the place where solar storms originate. The solar probe team Parker has just published The images closest to the sun They have ever taken. It is the first time that humanity sees with this level of detail the ejections of coronal mass and the field where its magnetic polarity changes from north to south. The Sun in the first -term term. When he took the images at the end of 2024, NASA’s Parker solar probe It was just 6.1 million kilometers of the visible surface of the sun: the photograph. That day, the probe not only became the fastest artificial object in history, with a speed of 692,000 km/h. He also used his WISPR camera to capture in detail the crown of the sun and the birth of the solar wind, the constant flow of loaded particles that bathes the entire solar system. The cradle of the space climate. The most revolutionary of these images is that they allow to visualize the weltic current sheet, a gigantic and undulating “sewing” of the solar system that extends from the sun, marking the limit where the polarity of the magnetic field is invested. Seeing it so closely is an invaluable document to understand how the solar wind spreads. In addition, the probe has managed to observe the collision and fusion of multiple coronal mass ejections in high resolution. “We are seeing the CMEs stacking on each other,” explains Angelos Vourlidas, scientist of the Wispr instrument. Understanding how they merge is key, since these mergers can Create geomagnetic storms Much more powerful and dangerous. The mystery of switchbacks. The Parker mission is not just beating proximity and speed records. Its main objective is to solve enigmas that solar physicists have been trying to decipher. One of the biggest discoveries of the probe has been the abundance of the so -called ‘switchbacks’ or Magnetic investmentsfolds in the magnetic field that invest their direction at brief intervals, as if Zigzag. Thanks to the approaches to the Parker solar probe, we now know that these structures originate on the visible surface of the sun and are one of the fast solar wind engines. Also that there are two types of slow solar wind. One seems to be born from large magnetic loops, while the other would come from coronal holes. Touch the sun without melting. Approaching the sun so much poses an obvious question: how is it possible that the probe does not melt? The key is in the difference between temperature and heat. The solar crown has a temperature of millions of degrees, but it is a vacuum with a very low density. There are few particles, so, although they move very fast (high temperature), they do not transfer much energy (low heat). How to put your hand in a hot oven. Even so, the ship needs protection. There your thermal shield of 2.4 meters in diameter comes into play carbon compound. The shield is capable of supporting temperatures of up to 1,400 ° C on its outer face, while the body of the ship remains comfortable 30 ° C. Other exposed instruments are made of exotic materials such as molybdenum and tungsten, metal with the highest known fusion point: 3,422 ° C.
