Nuclear energy has given you a key advantage that you are already taking advantage of

by

“I have a good friend on the other side of the ocean that says: ‘PERFORA, HAR Emmanuel Macron said this week in reference to Trump’s efforts to increase oil extraction. “But here it is not necessary to pierce. Here is only: ‘Plug, honey, plug!’ Electricity is availableyou just have to connect, ”added the French president during a summit on artificial intelligence (AI) held in Paris. The message is quite clear and reflects France’s intention to take advantage of its energy ecosystem as a strategic advantage to consolidate its role in the development of AI. The European country exported More than 90 Teravatios Hora (TWH) of electricity in 2024, which, according to the Government, allows it not only to cover the current needs of its companies and homes, but also host a large number of data centers. Nuclear energy, the key of France The aforementioned declaration of intentions has come accompanied by two ambitious agreements. As we pointed out at the end of last week, The United Arab Emirates committed themselves to make a multimillion -dollar investment in France to build a data center of 1 Gigavatio within a Largest AI campus in Europe. Yesterday Monday The announcement was formalized From the cloud AI platform Fluidstack. Fluidstack, a British firm with clients such as Mistral AI and Character.AI, plans to establish a 1 gigavatio data center on Gallic floor, completely driven by nuclear energy. It is expected that the first phase of the project, promoted by 10,000 million dollars (10,360 million dollars) to materialize in 2026. The agreement, which bears the signing of several French ministers, leaves the door open to later stages in 2028. As in many parts of the world, building a data center in France implies challenges, including bureaucracy. To facilitate the process, the Government has assured that the National Electric Management Company will guarantee the necessary supply. As a whole, this should be translated not only in a better position in France in the AI ​​career, but also the creation of “thousands of jobs” of research and infrastructure. France’s relationship with nuclear energy has evolved over time. A decade ago, the country announced a plan to reduce its dependence on this source from 70% to 50%, but in 2022 the strategy took a turn and the initiative was discarded. Instead of limiting its use, the government chose to expand it with the construction of new reactors. Currently, France has 57 reactors distributed in 18 plants. These movements are allowing the country led by Macron to gain advantage over other countries in the region and the world. Although data centers can operate with ENergía Solar and Windthe intermittency of these sources raises additional challenges. Nuclear energy, on the other hand, guarantees a stable supply and large scale. In addition, the new generation of small modular reactors (SMR) reinforces this scenario.

The minimum interprofessional salary is the minimum wage stop that an employee must receive for a complete working day. That makes it an effective tool to ensure that the lowest wages increase so that the lowest income Do not lose purchasing power. The Council of Ministers has given a green light to a new upris of the SMI by 2025 and will be retroactive. That is, it will begin to compute since January 2025. However, the Treasury has not raised the minimum of Exemption for IRPF As did on other occasions, so that increase will be subject to retentions. SMI climb. The Council of Ministers has approved An increase of 4.4% in interprofessional minimum salary (SMI) in Spain by 2025. Thus, the monthly gross amount increases by 50 euros, from 1,134 euros to 1,184 euros gross per month in 14 payments, or 1,381 , 33 euros monthly gross prorated in 12 payments. The total annual gross is set at 16,576 euros, which implies an annual increase of 700 euros. Some 2.4 million employees will benefit from this increase, of which 65.8% are women (1,579,000), and 26.8% correspond to young people between 16 and 24 years old. Since 2018, the SMI has increased by 61%, from 707 euros to the current 1,184 euros per month. The importance of SMI for part -time. The SMI is decisive to establish a minimum amount per hour in the remuneration of the partial days. With the arrival of the new climb, the amount will be 9.26 euros at the time, compared to 8.87 euros per hour of 2024, increasing in the same proportion as the rest of the SMI perceptors. IRPF has not risen. In each of the previous increases of the SMI, the exemption limit of the Income Tax for natural persons (IRPF) has risen at the same rate so that those who charge that minimum wage were not subject to retaining IRPF on their payroll, so the ascent went entirely to the worker. On the other hand, the Ministry of Finance has not adapted the retention tables to this increase, which means that this SMI increase will be subject to taxation and, therefore, have the obligation to pay IRPF to exceed the maximum of 15,876 euros per year that the Treasury set with the previous climb. That implies. Although the SMI is within The tax tablethat does not imply that all employees who charge the SMI will have retentions of the personal income tax, since the personal circumstances and their fiscal deductions also depend on this. A taxpayer with a couple and a child under three years of age will not suffer any retention in the IRPF. On the other hand, the same taxpayer who charges the SMI and has a child over three years old will suffer a retention of 90 euros per year over the 700 euros that has increased in total. On the other hand, a single worker and without children, will be the most affected by this retention since it does not have applicable fiscal deductions, so a retention of 1.81%is applied, adding a total of 300.05 euros to the year over the total of the 700 euros of increase. About 21.4 euros per month if calculated in 14 payments.

If ‘the snow girl’ has left you wanting, you can recover this 6 -episodes miniseries in Netflix with a similar argument

by

The second season of ‘The snow girl’ has become one of Netflix’s recent successes. If you have already finished with it and look for similar series, it is possible that this co -production between the United States and Germany that premiered in 2023 (curiously, very close in time to the first season of ‘The snow girl’) You are interested in its similarities with the adaptation of Javier Castillo’s novel. It’s about ‘my sweet girl’, It is also in Netflixand shows us a woman who has a curious relationship with her two children, with whom she lives retained under conditions of great security. His routine is very similar day to day and they have an order that must be fulfilled under any concept: to follow all the orders of a man who sometimes enters his room. One day, the mother manages to escape and has a car accident in the flight. In the hospital he will meet his parents, who have been looking for her for more than a decade. As you can see, a series full of turns and that is told from the perspective of the injured and semi -amnesic mother, the girl who knows endless secrets of her past life and, of course, the couple of police officers investigating the case. I inevitably remember films like ‘The Room’ and ‘Lost’that also handle issues related to disappearances for a long time and kidnappings that completely disconnect the victims of their families. If you still have any questions, a couple more data: on the one hand, it has a 100% critical score sweet In Rottren Tomatoeswhich undoubtedly makes it a very attractive proposal. In addition, it only extends by six episodes, so it is perfect for a high intensity suspense discharge that can be practically consumed of a sitting.

Apple Intelligence needed a Chinese partner and has already found it, according to ‘The Information’. The key is qwen

by

Apple needs a local partner to offer Apple Intelligence in China, where regulations demand that AI services pass through national companies. We knew that Apple had been looking for the ideal partner for some time, according to The Informationhe has found it in Alibaba. Why is it important. The absence of Apple Intelligence in China has weighed iPhone sales in the largest smartphones market in the world. The agreement could reverse this trend just when Apple plans to launch its AI in simplified Chinese in April, the same month in which It will arrive in Spanish. In Xataka Apple’s metamorphosis: from the minimalist catalog to calculated maximalism What has happened. Apple and Alibaba have jointly presented their AI functions for approval by the Chinese regulator. The alliance comes after Apple will rule out collaborating with Baidu for not reaching the required standards. Between bambalins. Apple was also probing possible alliances with Bytedance, Tencent and Deepseek Before opting for Alibaba. The choice was based on the robustness of the model Qwen from Alibaba and its ability to process personalized data thanks to its experience in electronic commerce. Also, Ahem, in Your alignment with socialist values required by the Beijing government. The latest. Alibaba’s actions They have triggered 3.5% After the publication of the news and accumulates 8% in two days. The market trusts the fruit of this operation between both companies. Alibaba’s Qwen model has gained reputation in recent months. Its potential was demonstrated when Stanford scientists managed to train a new reasoning model for less than $ 50 using Qwen as a base. S1 marked a before and after for the model.

Now any US smartphone can be connected for free to Starlink satellites. From July it will have a price

by

Spacex and T-Mobile took advantage of the Super Bowl to announce that the service of Direct cell connection with Starlink satellites It is already available in the test phase in the United States. The surprise is that it will be free until July, even for customers from other operators. Then it will become a payment service, accessible from any modern smartphone with ESIM. How T-Mobile Starlink works. Spacex has launched more than 7,000 Starlink satellites; 450 of them are Direct to Cell. In addition to offering Broadband Internetthese satellites function as telephone towers in space. When a T-Mobile Starlink user stays without coverage, his mobile will connect directly to the satellites that are passing over, and they will talk to each other to forward the messages to an earth station. Although at the moment the service is limited to sending text messages, in the future it will also allow voice calls and data services. Spacex has shown that Even video calls are feasible With Starlink Direct to Cell, but more satellites will be needed in orbit so that the company can offer a generalized use of this type of complex services. What devices are compatible. The connection with the satellites is direct and does not require parabolic antennas, as is the case with Starlink broadband. Any modern smartphone compatible with the LTE 25 band should be able to connect to Starlink Direct to Cell, although T-Mobile only mentions some examples: iPhone 14 or higher, recent Google, Motorola and Samsung devices, and the Revvl line of T-Mobile. In addition to T-Mobile customers, Verizon, AT&T and other operators can also register in the service with an unlocked terminal that ESIM admits. In the future, coverage will be international through alliances with operators from other countries. How much does the service cost. The great claim of the Super Bowl announcement is that T-Mobile Starlink will be free until July, be the operator you are. Those interested have only to Complete a form With your name, your email and your mobile phone number, accepting in return to receive T-Mobile marketing offers. The highs are carried out in order of arrival, which is generating demand peaks. But the thing will change from July, when the beta phase of the service ends. From that moment on, T-Mobile customers will have to pay $ 15 per month so as not to run out of signal without coverage ($ 10 per month if they take advantage of the starting offer). Customers of other operators will pay much more: $ 20 per month without discounts. It will soon reach other countries. Starting with New Zealand through the ONENZ operator. And following Australia, Ukraine, Canada, Switzerland, Chile, Peru and Japan. Entel is Spacex’s partner in the only two Latin American countries on the list. Starlink It is already a profitable businessbut Direct to Cell can only expand Spacex’s advantage over its competitors. No other company has the competitive advantage of reusing up to 25 times its own rockets. And when some get it, Spacex will have already started throwing satellites with Starship.

Buyers are registering it as a medical device

by

At the end of December we analyzed the Huawei Watch D2one of the most complete proposals at the health level in the smartwatch market. This clock can function as a tensiometer, a function of which you cannot boast any of its direct rivals. Vitaminate with Harmonyos, although with a price higher than that of clocks with similar specs (except for this function), it was raised as a more than interesting proposal. In China this clock is sweepingprecisely because of its tensiometer function. But the main reason is not the characteristic itself, it is that the Chinese have discovered something very important: they can load this expense to their medical insurance. After the launch of this device in China last November, the users of the social network Xiaohongshu, the new Chinese Tiktok, shared the data. This device is a blood pressure meter, so the Chinese state medical insurance covers the totality or part of the cost of the clock, depending on the city in which it is resided. The state medical insurance system is a medical coverage system that covers the vast majority of the population, composed of different programs as we reside in the city or in the rural environment. One of its characteristics is the direct refund system, through which it is enough to present the invoice of a medicine or health product included in the coverage to receive it. One of the obvious requirements is that the product must be prescribed by the doctor. In this way, those users who have prescribed a tensiometer can access a reim. Such has been the success of D2 in China that the device is completely exhausted. Image | Xataka In Xataka | Huawei Watch GT 4, Analysis: Two versions that squeeze the nuts to the Premium range

Thanks to this table we can finally understand how metals compatibility works

by

Materials science is an exciting discipline. It is likely that some people seem unattractive, and it is a respectable opinion, but objectively it is about A very important scientific branch. Its purpose is to study the structure, physicochemical properties and the behavior of the elements with the purpose of Design new materials which can be used in a very wide range of industries. The kevlar used in The bulletproof vests and the diaphragm of some speakers, among other applications; the carbon fiber used in the aeronautical, automobile and sports industries; high performance alloys used, for example, in nuclear reactors and The turbines of the aircraft; or the Carbon nanotubes which are already being used in some electronic devices support the relevance of the science of materials currently. Rufosity matters. And a lot One of the properties that usually study material engineers is roughness. This characteristic identifies often imperceptible irregularities that reside on the surface of a material. To measure them, it is usually necessary to carry out a microscopic analysis, but the really important thing is that this knowledge allows researchers to design and manufacture new components. And it is that roughness is an essential parameter that conditions the performance, durability and applications in which a new material can be used. In fact, there are research groups and companies that are dedicated in body and soul to characterize new materials and measure their roughness. Michigan Metrology It is one of these companies. It resides, as we can intuit, in the state of Michigan (USA), and expressly dedicates itself to measurement, analysis and inspection of roughness and wear of surfaces. To carry out their analysis, it resorts to very sophisticated teams that are capable of precisely identifying the irregularities present on the surface of the materials through a three -dimensional exploration. The table we publish on top of these lines has been prepared by the American mechanical engineer Ernest Rabinowicz, and is the Bible for Michigan Metrology and other companies that are dedicated to material engineering. In fact, it is the authentic protagonist of this article. And it is because it gives us a lot of information about the roughness and sliding compatibility of a good part of the metals that we can find in the periodic table of the chemical elements. Two pieces work better together if they are metallurgically incompatible, or, what is the same, if the metals involved are not dissoluble with each other As you can see, Rabinowicz occurred to be placed on the horizontal and vertical axes of the table the symbol that identifies each metal. And at the intersection between each pair of them appears A very illustrative symbol that identifies whether these two metals are incompatible, partially incompatible, partially compatible, compatible or identical taking as reference their roughness. In the field of metallurgy this information is very valuable. And it is because metals that are compatible from a metallurgical point of view tend to adhere to each other, a process that increases friction and wear. As we can intuit, knowing precisely the degree of compatibility between each couple of metals is fundamental in the design of the sliding interface between two metal pieces. In fact, two of these pieces work better together if they are metallurgically incompatible, or, what is the same, if the metals involved are not dissoluble with each other.

Low intensity magnetars are among the most unique objects of the cosmos. We are now discovering their secrets

by

The Magenetares They are among the strangest objects in the universe. The key characteristic of these neutron stars is their magnetism, but understanding the origin of this is not so simple. Explaining magnetism. Now a new study He has revealed That the origin of the magnetism of some magnetares, the so-called “low intensity”, is found in a phenomenon we call Tayler-Spruit dynamo. The new job, explain those responsible, resolves a mystery emerged more than a decade ago. Of low intensity. Magnetares are neutron stars, objects of great density that arise after the outbreak of some supernovae that give the death of large mass stars. These objects are characterized by their magnetic fields although, as we have discovered in recent years, these fields are not always comparable. Low intensity magnetares objects have between one and 10 tera-gauss (between 0.1 and 1 giga-tesla), which is one or two orders of magnitude lower than what was used to be considered defining in the “classic” magnetars. Despite this low intensity, this type of magnetar produces x -ray emissions similar to conventional ones. The important difference in the intensity of the magnetic fields of one and the other have led astronomers to press that the magnetism of each other has a different origin. Simulating a star. To understand what was happening in low intensity magnetars to generate their peculaires magnetic fields, the team responsible for the new study He turned to a numerical simulation with which they modeled the magnetic-thermal evolution of these objects. They observed a “dynamo process” (called Tayler-Spruit) that was given in the proto-strolle of neutrons, a process capable of generating low intensity fields from movement such as those observed in this type of stars. Relapse. According to Explain the responsible teamthe key is in the birth of these neutron stars, in the explosions of the supernovas in which they originate. As the model shows, the great of the star expelled in the outbreak ends up falling back to the new neutron star, which makes this faster unleashing this dynamo of Tayler-Spruit The details of the work were published In an article In the magazine Nature Astronomy. Five of 30. Magnetars are objects on which we still have much to learn. To illustrate this a fact can be useful: to date we have only discovered about thirty of these objects in the immensity of the observable universe. Of these only five are what we call low intensity magnetars.

Saudi Arabia has sealed a key pact to dominate the AI

by

Saudi Arabia is launched into the conquest of the Artificial Intelligence (AI)entering fully into the battle to lead one of the most promising businesses of the moment. The country, whose economy continues to depend largely on oil, has been looking to diversify its sources of income for years. A key piece of this ambitious plan is neom, A futuristic city that, for now, resembles more an industrial estatebut that aspires to become a luxury tourist destination and an innovation center. Oxagon, the city’s industrial center, will be the headquarters of a huge 1.5 Gigaw Data Center. Until now, most of the language models we use have been trained in infrastructure that operated on the megawatt scale, but the industry is stepping on the accelerator towards the gigawatts. There are the projects announced by goal and Oracle To prove it. This runaway growth is also exerting pressure on the energy sector of many countries. A “sustainable” project raised in several stages According to a statement released this weekthe Saudi Datavolt company will be in charge of leading the works. It is not yet clear if they will begin this year, but it has been confirmed that the data center will be built in phases. The initial investment, of 5,000 million dollarswill allow operations to start in 2028. From then on, the capital flow is expected to continue and that the works continue to advance until reaching the expected power, all under a “sustainable” approach. The announcement indicates that the data center will have “an integrated high density computer ecosystem and an energy efficient infrastructure.” One of the promises of the NEOM is sustainability. The government has promised that it aims to produce “100% clean” energy from sources such as solar energy, wind energy and the largest hydrogen plant in the world. It is no secret that they will need a lot of energy to boost this and other AI data centers in the place. The International Energy Agency (AIE) He has indicated thatin 2022, the global electricity consumption of the data centers was between 1 % and 1.3 %, and everything indicates that it will continue to increase significantly in the next decade. This scenario is promoting a Resurgence of nuclear energya source capable of satisfying the needs of large data centers and doing it stable. Now, it remains to be seen if Saudi Arabia, that still does not have nuclear plantsHe will advance in his plans. As Datavolt has pointed out, the project aims to turn Saudi Arabia into a regional reference in digital innovation and artificial intelligence. However, it is not the only country in the Middle East that aspires to lead this technological career. United Arab Emirates is also betting strongly in that regard, and proof of this is its recent multimillionaire investment To lift in France a 1 Gigavatio AI data center, part of the largest AI campus in Europe.

Almost everyone washes their teeth, but only one in 10 does well. And that is enough to do it twice a day

by

“Almost everyone brushes their teeth,” a group of researchers concluded from the University of Gottemburg in 2012. The problem is that “only one in ten does well.” The results were limited to Sweden, but from what we know They are still perfectly valid In the western world: we dedicate a disproportionate amount of time and resources to clean our teeth badly. Not only is citizens’ fault. And is that, As the BBC explainedstudies have found at least “66 different types of expert advice, sometimes contradictory to each other.” So we have asked ourselves … What does the evidence available about washing your teeth? How to wash your teeth? The most effective way to wash our teeth is one that understands what we wash them for. Usually, we usually believe we brush to eliminate food from the mouth; But there is something else. The teeth develop a dense biopay (the dental plate) that surrounds it and that is not easy to remove only with a rinse. We brush our teeth to remove that sticky layer manually and as much as possible. To remove it from the teeth and gums, of course. There is several techniques for thisbut now we are going to focus on the most important: that “the movement should not be made horizontally, but the brush must move from the gums to the lower part of the tooth,” explained the dentist Juan Casado Adam. And travel all the teeth, one by one, without much pre -mud or hurry. How many times do you have to wash your teeth? At least twice, Experts tell us: One before going to sleep and another as soon as we wake up. It may seem strange, but it has its explanation: saliva has a key role in inhibition of the bacterial plaque. But while we sleep we produce less saliva. Like, while we sleep, our mouth becomes more hospitable To bacteria, prior washing helps eliminate ‘waste’ that bacteria can use to develop their activity and weaken the enamel. Therefore, the washing after waking ourselves has as a key function to renew the medium loaded with bacteria that we have in the mouth and help saliva to fulfill its function. Do not you wash your teeth after meals? Actually, using medium hardness brushes, we can brush our teeth as many times as we want. And yes, it is usually a good idea to do it after eating because we remove waste that bacteria could use. However, there are exceptions: if we have consumed a lot of acidic drinks (“such as soft drinks, coffee or alcohol”), sweet or we have vomited, brushing can immediately be an error. According to Luis Cabezas Vallejo, pediatric nursewhen the pH of the mouth is acidic, the enamel weakens and brushed at that time, it can cause damage (even if they are unappreciable). As Juan Carlos Llodra explained in ABCDeputy Secretary of the Executive Committee of the General Council of Dentistas Colleges of Spain, in that situation it is better to wait, let the saliva neutralize the acids (or sugars) and then brush.
