The US has just signed its first crypto law

by

In the middle of the Tariff storm and the changing Scenario of the commercial war with China, Donald Trump has had time to repeal one of the most important laws of IRS (Internal Revenue Service) About the Defi world. Thus signs its first American law related to the crypto scope, one that completely repeals the extension of tax report obligations to decentralized finance platforms. IRS legislation. In 2023, at the end of his mandate, Biden established The first National Strategy of the United States Towards the Critpo world. Signed a bill that It harden The fiscal declaration requirements by the Defi platforms. All under the position of “dealing with the risks and taking advantage of the potential benefits of digital assets and their underlying technology.” These requirements were designed to regulate statements to entities that “regularly make sales of digital assets.” Among them, wallet suppliers and other non -custodian platforms. Treat them as banks. This was wanted to establish that decentralized financial platforms had the same fiscal declaration requirements as centralized banks or traditional stock market runners. The new rule required that finance platforms report both transactions and user information to the IRS, the federal instance of the United States government in charge of tax collection and compliance with tax laws. Completely repealed. Four years later, Trump signs a resolution that eliminates the norm of the IRS aimed at Defi platforms, revoking the tax regulations imposed by the previous administration. It is officially the first effort in favor of the crypto world materialized by the new government. “The IRS Defi Broker Rule unnecessarily hindered American innovation, violated the privacy of Americans and was destined to overwhelm the IRS, which does not have the infrastructure to handle during the tax season, with an excess of new presentations. By repealing this rule, President Trump and Congress have given the IRS the opportunity to focus on the duties and obligations he already has with US taxpayers instead of creating a new series of bureaucratic obstacles, ”. Mike Carey, member of the Republican Party.” The Trump administration considers the newly repealed norm as a “bureaucratic obstacle.” A little more anonymous, but not quite. The repeal of the IRS rule by Trump does not eliminate the obligation to declare cryptocurrency profits. Eliminates the obligation by the platforms to collect and report transactions directly to the IRS. The Defi Broker rule required that asset wallet suppliers to submit reports to the IRS about operations. Something that will no longer have to do. The entry into force of the new reform has been accompanied by a slight rise from Bitcoin and other crypto, in a positive trend during these last hours. The next step. Uploaded the first step, the Trump administration He now heads towards Stablecoins. During the crypto held at the White House on March 6, the Treasury Secretary, Scot Besent, clarified that turning the dollar into the dominant currency went on to rely on Stablecoins. The Stablecoins They usually have a value of 1: 1, that is, a cryptocurrency equals a dollar. This parity allows them to maintain stable value, avoiding the volatility of other crypts. The Trump administration wants to foster its use to reinforce the dollar … and for pure personal interest of the president. Trump’s crypto. World Liberty Financial, cryptocurrency company supported by Trump and his family, announced on March 25 the creation of USD1a stablecoin linked to the US dollar. It is a project in which an obsession of the President materializes again: to enter personally in the crypto market. Prior to his appointment he launched $ Trumpa memecoin whose tokens distribution was at 10% public provision and 89% in the hands of companies linked to the president.

The European Union has an ace in the sleeve to negotiate tariffs with the United States: digital services

by

The United States is the great world importer. Its economy is the paradigm of consumerism, and China – the great world factory – has taken advantage of it. Precisely Trump’s tariffs –now in pause in almost everyone– They intend to correct that deficit, but not only with China, but with everyone. And the European Union, one of the affectedhas its particular As in the sleeve: its deficit in services. The EU is what the US to the goods. The European Union is a great services importer. In the old continent we are eager consumers of digital services that come from the US and ranging from the subscription to Netflix to the use of platforms such as Azure or AWS. The situation in services is similar to the one Trump wants to correct, but in that USA panorama it is “our China” and the EU would be the US. Europe has digital services deficit. And von der Leyen knows. Ursula von der Leyen, president of the European Commission, has already made it clear that the shots can go in the negotiations for tariffs. As they point out in Financial Timesthe president indicated that the EU will seek a “completely balanced” agreement with Washington during the 90 -day truce to the application of the reciprocal tariffs announced by Trump a few days ago. Trump makes the accounts that agree. The European Parliament already published a study Preliminary of what would happen if the US imposed extra tariffs on EU products, and detailed what the situation of imports of goods and services was. The US only talks about goods (Goods’) of consumption in its analysis, and does not mention the services for a simple reason: it has a deficit of goods (it loses) but surplus of services (it is winning). The EU is losing in services, and if the US applies tariff But it is that the US exports services to every cloth. As they also point out In The Wall Street JournalTrump’s mathematics ignore digital services exports. The former leading role of the United States as a manufacturer, with Ford or General Motors as great examples, has changed: now there the protagonists are the services, but the tariffs raised by the US government take them out of the equation, and that clearly affects the EU. In danger. According to the European Parliament data, in 2023 the EU had a surplus of goods and USA had a service surplus. In the Global EU had a surplus of 48,000 million euros, but in the study they indicate that it is a modest figure that “only represents 3% of the total commercial flow, 1.6 trillion euros.” Tariffs to services. If these negotiations fail, explained von der Leyen, the EU will expand the global trade war on services. The idea would be to include an income tax for digital advertising, something that already outlined with the DSA. The measure could have a remarkable impact on the income of companies that depend on the advertising model such as Meta, Google and Facebook. Evening threats. “We are developing retaliation measures,” said Von der Leyen, noting that “there is a wide Ramgo of countermeasures … in the event that negotiations are not satisfactory.” The advertising tax would be applied in Europe and would be different from taxes to digital sales, which have independent tax burdens according to each Member State.

After matching his space bet, Jeff Bezos has invested in the other great Elon Musk project: electric cars

by

Jeff Bezos is financing under a startup of electric vehicles called Slate Auto, which works since 2022 in a Pickup Compact and affordable with an expected price of $ 25,000, as it has revealed Techcrunch. Why is it important. This investment is a very different approach to the one followed by the majority of electric startups, which have opted for luxury models with high margins. Slate Auto changes the usual strategy when directing directly to the mass market, that of the general public. And just at a time when the growth of some brands has slowed down. In the case of Tesla, has collapsed. Between bambalins. The company was born as part of Re Manufacturing, another company supported by Bezos and co -founded by Jeff Wilke, former CEO of Amazon Consumer. Since then, he has attracted several executives from Ford, GM, Stellantis and Harley-Davidson, in addition to several former Amazon ex-employed. The figures. Slate raised at least 111 million dollars in a series A round in 2023, and according to documents from the state of Delaware mentioned by Motorpasionhas authorized about 500 million preferential shares for a series B $ 2.37 per share. That is, almost 1.2 billion dollars. In addition to Bezos, the company has the investment of Mark Walter, majority owner of the Dodgers, a baseball team, and Thomas Tull, main re manufacturing investor. The strategy. The Pickup of two Slate places follow a minimalist philosophy inspired by the Ford Model T and the Volkswagen Beetle. The company’s plan is to compensate for the low margins of the vehicle with an accessories line for customization, similar to the Harley-Davidson business model or division Mopar of Stellantis. And now what. Slate plans to start production at the end of 2026 in an installation in Indiana. During these days a prototype of the car in Los Angeles has been sighted and photographed, showing a simple and functional design, published in Reddit and collected by Carscoops. Far away from the futuristic lines of a possible rival like the Cybertruck of Tesla. Expected that, after the exclusive Techcrunch And the first photo of the prototype, the company is encouraged to share some more information than until now, where it has been cryptic in its communications.

China responds to the US with 125%tariffs. It no longer makes sense to upload them more

by

The US has been significantly increasing tariffs on Chinese imports: rose from 20% to 54% April 2, then to 104% the April 8 and finally at 145% April 8. China has been responding. Rose from 10% to 34% April 4, then at 84% On April 9 and now he has just announced a last response, uploading the tariffs to US imports to 125%. And now what? China counterattacks. On Friday the Chinese Ministry of Economy advertisement The new tariffs with a striking message: at this point they already give equal future ups of tariffs by the US. “In view of the fact that there is no possibility of acceptance in the market for US goods exported to China with the current tariff level, China will not pay attention if the US part continues to impose tariffs on Chinese merchandise exported to the US in the future.” “A joke”. According to indicate In The Wall Street Journal, “although USA continued imposing higher tariffsit would not make sense from the economic point of view and would become a joke in the history of the world economy. “Indeed, with those tariff levels to producers no longer compensates for trying to sell their products in countries with these tariff levels. It makes no sense to upload them more. Zhiwei Zhang, president of the consultant Pinpoint Asset Management, indicated In CNBC that “this is the end of climbing in terms of bilateral tariff fees. Both China and the US have sent clear messages, and makes sense to upload tariffs beyond.” Talks? It does not seem that there is intention to initiate negotiations between the two countries, something that can cause colossal disruption in world supply chains. Even so, a spokesman for the Chinese Ministry of Commerce indicated In an additional statement that Beijing is open to negotiate with the United States on equal terms. The primary sector in danger. China exports more than it matters, but there is a sector that can be very punished by these tariffs, and that is the primary sector of American farmers and ranchers. That same segment is the one that has given many votes to Donald Trump in the elections. Soybean, a worrying example. The soybean industry is According to The New York Times one of the great affectedBecause China is the most important market for soybeans exported by the US. According to the US International Trade Commissionthe segment of “grain, seeds and fruits” represents an exports of $ 13,350 million, 11% of total exports to China. Above is just oil.

He will be able to continue selling his H20 GPU for AI in China, although he has cost him a 1 million dinner per diner

by

The GPU for applications of artificial intelligence (AI) H20 is the salvation of Nvidia in China. Since the sanctions package officialized by the administration of Joe Biden entered into force November 16, 2023 This is THE ONLY SOLUTION FOR IA That Jensen Huang’s company can sell to its Chinese clients. And, in addition, during the last months it is being a real success. This chip on paper is much less capable than the most sophisticated GPUs that Nvidia currently sells. In fact, this is the reason why the US Department of Commerce has allowed its sale in China in recent months. Its limitations invited us to initially assume that their reception in this Asian country would be warm, but It has not been so at all. According to Business Intelligence semiconductorsince this chip reached the Chinese market in mid -2024 its sales have grown 50% quarter to quarter, which positions it as the most successful Nvidia product today. However, sales of The H100 GPUwhich is more powerful, “only” grows 25% quarter after quarter. In spite of everything since the end of 2024, the H20 Chip is undergoing the scrutiny of the US Department of Commerce. Jensen Huang has added one of his most unlikely successes Gina Raimondo, the Secretary of Commerce during the mandate of Joe Biden, He made this warning to Nvidia In December 2023: “If redesign a chip so that it can be used for AI, we will control it the next day.” The direct allusion to the Jensen Huang company is evident. The return to the US government of Donald Trump and his collaborators far from appeasing the panorama promised to end once and for all for the sale of the H20 GPU in China. The Nvidia business in China has resentful during the last two years as a result of the sanctions imposed by the US For Nvidia this restriction would be a very hard blow. His business in this Asian country has rented during the last two years as a result of the sanctions imposed by the US, and stop selling the GPU that during the last months He has sustained this company in China I would make a difficult wound to heal. These are the circumstances in which Jensen Huang has met with Donald Trumpand has done so with a firm purpose: to ensure that the government allows Nvidia to continue selling its H20 chip in China. The Trade Department, which under Trump’s mandate is being led by Howard Lutnick, intended According to several filters to prevent this week that this GPU continue to arrive in the country of Xi Jinping. However, against all forecast the US administration has suspended, at least temporarily, its export prohibition of this chip. This conclusion is surprising, but there are even more circumstances in which Jensen Huang has achieved his goal. And it is that the general director of Nvidia has approached this negotiation directly with Donald Trump during a dinner at the restaurant of the Mar-A-Lago tourist complex housed in Palm Beach (Florida), which is owned by the latter. It has transcended that Huang and the other diners They have paid a million dollars each for attending this dinner. But Huang has compensated. Nvidia can continue selling its H20 GPU in China. At least for the moment. Although, yes, he has pledged to invest more money in data centers for the US.

Silicon Valley millionaires want to lift their own Neom. They have an ace in the sleeve to convince Greenland

by

In the list of projects that sought to create self -sufficient enclaves outside the State there are several examples. We have the Failed project north of San Francisco, Prosperous in Honduras or the Seasoning attempts In international waters. Also hyperbolic projects on the way, Like Neomall ideas that have shared a common vision: experiment with radical economic models and alternative governance, backed by millionaire capital and an almost ideological faith in without restrictions, although few have passed the prototype. Greenland looks like the next stop. Silicon Valley and “freedom.” We tell it A few months ago: the Trump administration has reactivated its ambition to acquire Greenland, but not only as a goal strategic and geopoliticalbut also as a scenario for an initiative promoted by technological billionaires. We talk about the creation of a high -tech libertarian city, known as “Freedom City”. Inspired by ideals of extreme and free market deregulation, this vision contemplates a self -sufficient enclave dedicated to the development of artificial intelligence, autonomous vehicles, space releases, nuclear microreactors and high -speed trains. According to Reuters revealedthe plan has already been discussed in private among investors such as Peter Thiel, Marc Andreessen and Shervin Pishevar, all with a history of similar projects, and has the explicit interest of Ken Howery, former ambassador to Denmark and key figure in negotiations for the possible annexation or purchase of the island. Howery, close to Trump and Elon Musk, has expressed Enthusiasm for potential Of cultural and geographical synergies between Taiwan, the United States and Japan, and although he refused to comment on the plans, several medium sources say that their role would be crucial to advance the idea. All roads lead to Greenland. The choice of the island is not accidental. Three times bigger than Texas but with Just 57,000 inhabitantsthe island has vast strategic mineral reserves, including rare earths, and houses an American military base that gives it a huge geopolitical value in the Arctic. Trump has publicly insisted that “We must have Greenland” and has not ruled out take it by force If Denmark refuses to sell it. In fact, his vice president, JD Vance, recently visited the military base with his wife, which It generated protests of the local population and harsh criticism of the new Prime Minister of Greenland, Jens-Frederik Nielsen, who considered the visit as a disrespect to the sovereignty of the island. During the same, Vance accused Denmark of not properly protecting the territory of alleged Russian and Chinese incursions, although he did not contribute concrete details. Meanwhile, the Danish government declined to comment on the rumors of a technological city funded by American private capital. A new doctrine. The proposal to build a libertarian citizen in Greenland reflects a broader ideological movement among businessmen from Silicon Valley, which for years promotes the called “Startup Cities” or “Charter Cities”: urban enclaves with minimal state intervention, designed to promote innovation and self -sufficiency. We already count The Prospera caseand now, inspired by the philosophy of “manifest destination”From the nineteenth century, its defenders see in Greenland the opportunity to open a new border for the American Expansion and Domain experiment, this time in technological key. SHERVIN PISHAR He described the initiative as “the dawn of a new manifest destination”, while Dryden Brown, co -founder of the Praxis projectargues that Greenland is the ideal place to build a prototype city that serves as a general essay for future human colonies on Mars, in line with Elon Musk’s interplanetary dreams. Brown even traveled to Greenland and has assured that other companies have raised him collaborate at the Foundation of that city. In an X publication, wrote: “We must build a prototype of Terminus on Earth before leaving towards Mars. Greenland is that place.” Investors and power networks. The impulse behind this ambitious proposal comes from a consolidated group of technological investors, many of them linked to each other through previous projects. Thiel, Andreessen and Pishevar have invested in Pronomos capitala firm dedicated to financing experimental cities in countries willing to offer special regulatory conditions. One of his main advisors, Patri Friedman (grandson of economist Milton Friedman) has confirmed that several of their projects are in the negotiation phase with governments and that one, Prosperousalready operates in Honduras under a similar model (although with rather terrible results). In addition, Praxis, backed by figures such as Joe Lonsdale and Sam Altman’s background, has raised More than 500 million of dollars to develop a new city, and could channel part of that capital towards Greenland. While Thiel denied being involved in specific plans for the Island and Musk has not commented on this, the connections between these actors and their historical interest in technological secession projects reinforce the credibility of the initiative. What they offer to the locals. Unlike the Trump rhetoricthese billionaire investors have an ace in the sleeve to convince the people of the island, one where the exploitation would make the enclave A unique space. During a hearing before the Senate Commerce, Science and Transportation Committee, experts argued that the Costa de Greenland houses one of the highest critical mineral concentrations in the world, many of them previously inaccessible because it is under thick layers of ice, but that they could become exploitable due to the melting caused by climate change and the development of new mining techniques. There is more, of course. For project drivers, Greenland is not only a geopolitical opportunity, but also an ideal platform to experiment with advanced technologies and urban models of the future. Technological investors that promote the creation of a Freedom City offer the local population an accelerated economic development vision, based on the Job promisewealth and technological opportunities in an environment of minimal regulation. They also raise the territory into a Global Innovation Center With high -value industries such as AI, clean nuclear energy, advanced transport and space exploration, which would imply massive massive investment and modern infrastructure. In addition, some actors close to the Trump administration have suggested to replace … Read more

Goodbye to the ruinous business in Latin America … and Diana on Digi and Vodafone

by

Marc Murtra, just ratified As executive president of Telefónica with a support of 90% of shareholders, they have a forceful message: the priority is “Europe, Europe and Europe”, and the consolidation within each country is essential. He already anticipated it In an inaugural speech of the MWC full of intention. The “intramerous” mergers are, in their opinion, the only effective way to generate real synergies, reduce costs and improve profitability in a sector that has languished for years. While Abandon Latin America After a ruinous business attempt there, Murtra focuses on operators such as Vodafone Spain and Digi, according to Expansionwith sufficient scale to impact. Why is it important. Murtra’s message to the European Commission, the CNMC and national governments is clear: mergers within each country are priority over any paneurpea consolidation, and regulators must allow them. This approach is a change with respect to the previous position of the EC, which has hindered similar mergers in the last decade. Orange and MasMóvilwithout going any further, he lasted a lot and filled with asterisks. However, recent letta and draghi reports on European strategic autonomy give intellectual coverage to this position. Murtra relies on the new geopolitical climate, where European technological sovereignty is at staketo claim conditions that allow European telecos to gain financial muscle and compete globally. The contrast. While in Europe it seeks to grow absorbing competitors, in Latin America Telefónica is in full withdrawal, after years of negative results that have undermined their financial position. Peru is already in creditors. Argentina has been sold for 1,190 million euros to the Clarín group (although Milei’s government tries to block the operation). Colombia is about to go to Millicom. And Mexico is the following in the list for divestment. Only Brazil remains as a strategic market, contributing about a third of the group’s profitability and being even more priority than Spain in terms of investment. What’s happening. The European consolidation strategy proposed by Murtra reflects a reality of the sector: Europe has 34 main operators for 450 million people, while the United States has only three for 335 million. This fragmentation is a lifeline. The European Telecommunications Sector has lost 41% of its capitalization since 2015while American and Asian giants advance technologically much faster. Telefónica’s stock market value fell 57% under the Álvarez-Pallete mandate despite reducing debt by half. The European 5G coverage (81%) is delayed with respect to the American and China (more than 95%). The average income per mobile customer in Europe is 15 euros compared to $ 42 in the United States. Fiber customer yield is 13 euros in Europe against $ 58 in the United States. Between the lines. Vodafone Spain and Digi arise as the logical objectives for consolidation in Spain. Only these operators have enough scale to generate multimillionaire synergies. Vodafone, with almost three million broadband customers, or Digi, who already exceeds two million fiber users, represent acquisitions with the necessary volume to move the needle in the Spanish market and contain the competition that is eroding its margins. Other assets such as Avatel, FI Network or Adamo would also be intent, but have too small dimensions for their purchase to have the impact that Telefónica seeks. Yes, but. Telefónica’s transformation goes beyond traditional consolidation. 43% of their business income in key markets already come from services that are not communications. The operator is close to the inflection point where most of your billing comes from technological servicesnot voice or data. The IT segment is growing “in double digit” while reducing the investment ratio on income from 12.9% to 12.5%. This metamorphosis reflects the search for a post-terocommunications identity, where Telefónica wants to be defined as a diversified technological company. Now the crystallize narrative is missing. And now what. Murtra has announced that he will present his strategic plan before he finishes 2025, with three priorities: focus on Europe, “iron financial discipline” and technological excellence. What remains to be seen is whether the European Commission, with The new Teresa Ribera Commissionerwill respond favorably to its requests with greater consolidation. And if Murtra will execute both Latin American divestments and European acquisitions with the rapidity it promises. If it works, it could mark the way for other European telecos trapped among American technological giants and Asian manufacturers. If it fails, the decline of the sector in Europe could become irreversible.

We have compared the effects of the Mediterranean diet with those of the so -called “planetary health diet”. There are surprises

by

Something everyday as eating can have a huge impact on our health, but you can also put a small grain of sand in environmental protection. The problem in these cases is that it is not always easy to demonstrate reliably the impacts of our diet on our health and the environment. Some scientists have tried. As beneficial as the Mediterranean diet. A group of researchers He has been studyingface to face, the health and environmental effects of two diets: the traditional and well -known Mediterranean diet, and the least known planetary health diet. According to this analysis, adhesion to both diets presents similar benefits for both our health and our environment. Planetary health diet. The planetary health diet, or PHD for its acronym in English is a diet Proposal in 2019 By a group of experts from the Eat-Lancet commission, associated with the medical magazine The Lancet. It is a diet that prepares the consumption of plant foods and limits the consumption of meats and dairy products (although it does not eliminate them as in vegetarian and vegan diets). “In 2019, the planetary health diet (PHD) was developed to optimize global dietary quality at the same time that the impacts of food production within sustainable borders were maintained,” indicated in a press release Mercedes Sotos Prieto, researcher at the Autonomous University of Madrid and co -author of the study. “However, evidence of how PHD is compared to the Mediterranean diet (…). We have evaluated the effects of both diets on mortality for any cause and the environmental impact on a large (sample) representative of the Spanish population.” 11,488 participants. The study was carried out from compiled data in the study of nutrition and cardiovascular risk in Spain (Enrica). The data of this cohort allowed to track 11,488 participants over 14.4 years. To analyze the adhesion to each of the diets two indexes were used, the PHD Index and Medas Score. These measured the consumption of certain foods associated with each of the diets, the planetary health diet and the Mediterranean diet, respectively. The environmental impact of these forms of food consumption was carried out through the Sharp-ID tool (Sharp-Indicors Database), which allows estimating greenhouse gas emissions based on land uses. Health impacts were measured through mortality, through the National Death Index. The analysis also included information about other variables to adjust the results. Less mortality. The study results They indicated a positive effect of both diets about health. In the case of the PHD, the study showed a decrease of approximately 22% in the risk of death during the period studied when comparing the group with greater adhesion to this diet with respect to the group with less adhesion. In the case of the Mediterranean diet, the comparison between the mortalities of the groups with the greatest and lesser adhesion was approximately 21%. A very similar positive effect, so much that the difference is statistically irrelevant. More than health. The second point of interest is that of the environmental impact of diets, calculated in this case based on emissions that are estimated to the different options. In the case of the PHD diet, the estimate calculates emissions equivalent to 4.15 kg of CO₂ a day, with a soil use estimated at 5.54 m² a day. The Mediterranean diet, on the other hand, is calculated emissions equivalent to 4.36 kg of CO₂ per day, with a land use estimated at 5.43 m² a day. Results, again, very similar. The details of the study have not yet been published in a scientific journal, but were presented at the beginning of the month at the Congress of the European Society of Cardiology (ESC). An open debate. The PHD diet is a relatively recent formula, proposed less than a decade ago. In his presentation it was received with a certain degree of skepticismsomething logical if we take into account the difficulties facing science when analyzing something as complex as nutrition and the effects of food on our body and our health. That is why studies are required to test the Initial results. Experiments such as this incline the balance in favor of this type of diets but when addressing this type of issues all additional information can be useful.

What is Google Firebase Studio and how this tool works to create artificial intelligence applications

by

Let’s explain what Google Firebase Studio is, the new tool for Create applications with artificial intelligence. You can do it without writing a line of code, just describing Google’s AI what you want, so that it generates the code for you. At the end of the process, you will have a functional web application that you can use and publish to see the light. Obviously, this is only prototyped, because you will also have the option to edit and review the code on your own to make sure everything is fine. What is Google Firebase Studio Google Firebase is the Webs and Applications Development Platform Created by Google. The idea is to cover most of the needs of developers, being able to store software, provide notification system for apps, necessary databases and authentication services or use analysis. And in 2025 Google has created Firebase Studio, which is a section within this platform that allows you Create webs and apps with artificial intelligence. You do not have to do anything, it’s something like Vibe Codingwhere AI generates the code and you just have to check it. The idea of ​​this service is that you simply have to Describe the type of application you want to create. For that, you must define what you want me to do in detail with a natural language. You have to describe what you want to do with the app, how it should be, its functions and anything else you can think of the same as if you will explain to a person. For this, Google Firebase Studio uses Geminithe artificial intelligence system of the company itself. Specifically use Gemini 2.0 Flashwhich will be the one that is responsible for interpreting your description, and to generate the application code in a few minutes. Of course, remember that what this tool will generate They are applications prototypes. Once you have it, you may have errors, and you will have to check the code, make the corrections you want and click on Post so that Google is in charge of hosting her. How to use Firebase Studio The first thing you have to do is enter the Firebase website, whose address is Firebase.google.com. Once inside, click on the button Begincontinue with the introductory steps that appear when you are going to use this program for the first time. This will take you to the Firebase Studio page, whose address to enter later is Studio.firebase.google.com. The tool interface is similar to that of an artificial intelligence chatbot, you have a writing field where you should Define what you want the application to do. Then click on Prototype with AI. This will take you to a Gemini page, where you are shown Suggested options and design For this application, as well as a name. On the right you have the icon of a pencil in case you want to make changes in the suggestion. When you have the app as you want, click on Prototype This App To create it. If you click on the edit button with the pencil iconyou will go to a page where you can manually change what you want within the description, including colors or functions. You also have a field to write the changes you want to make and that the AI ​​is in charge. When you finish click on Save. You will also have a button Prototype This App To start creating it from this window. And that’s it, then you’ll see in front of your eyes how the application code is createdand how after doing so, possible errors are sought and corrected. And that’s it. When you finish you will have a demonstration of the application to try it, and below you will have the button Edit of Code to review and make changes in the code. Up to the right you have a publishing button so that the web application is accessible. In Xataka Basics | Gemini Advance functions that become free in March 2025

Astronomers have seen live the awakening of a giant black hole. They had never detected something so violent

by

Good morning, Ansky. SDSS1335+0728 was a black hole so boring that it didn’t even have a nickname. Located 300 million light years, in the constellation of Virgo, he had been asleep from our point of view. But go aroused. The supermassive black hole has aroused in such a violent way that it has left fascinated and somewhat baffled astronomers. Now it is an active galactic nucleus (AGN) dodged affectionately “Ansky”. Years of study. The galaxy where Ansky is began to shine unexpectedly in visible light at the end of 2019. Chilean astronomer Paula Sánchez Sáez, of the Southern European Observatory (ESO), leads the first team that detected activation. “When we saw Ansky illuminate in optical images, we activate monitoring observations with the NASA X -ray space telescope and review archived data of the erosite German telescope,” Paula says in a statement. “But at that time we did not see evidence of X -ray emissions.” The surprise arrived in February 2024. A second team led by Lorena Hernández-García, from the University of Valparaíso (in Chile), saw how Ansky began to emit gusts of incredibly energy and regular X-ray. “It is the first time we observed such an event in a black hole that seems to be waking up,” Lorena explains. Out of the ordinary. He XMM-Newton telescope From the European Space Agency it has allowed to measure the faint x -ray light that comes to us from the explosions, which has been key to measuring how much energy releases Ansky in each “flash”. Known as “quasiperiódicas eruptions” (QPES), X -ray emissions turned out to be ten times longer and ten times luminous than other supermassive black holes. Each eruption of Ansky releases a hundred times more energy than the Qpes observed so far. In addition, it had never seen a time between eruptions so wide, with a cadence of four and a half days. Ansky takes astronomical models to the limit and challenges our current ideas on how these flashes are generated. What causes these explosions? The most accepted theory about the QPES is that they are caused by the interaction of an object (such as a smaller star or hole) with the accretion disc (the hot and bright material that revolves around the black hole before being engulf). They usually occur when the Black hole is eaten a starbut it does not seem to be the case of Ansky. This has led the international astronomer team to consider other possibilities. Perhaps the accretion disk will be formed from gas captured from the galactic environment, and the flares are the result of highly energetic shock waves caused by a smaller object that orbit and disturbed repeatedly the disc. Gravitational waves. Notice Real Time Awakening It is an unprecedented opportunity to check if their energy eruptions could be related to gravitational waves, predicted by Einstein’s relativity and detected for the first time a few years ago. The smooth mission of ESA and NASA will try to observe these disturbances in the space-time fabric from point L1 of Lagrange after its launch in an Ariane 6 rocket planned for 2035.
