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.

Opinions, first contact and photos

The transition to the electric car The Volkswagen group has been choking. His ID.3 It did not become the Volkswagen Electric Golf they expected. Their ID.4 and ID.5 They have had better results but they have not been the supervants that were guessed. In its high range, the Porsche Taycan It started in an extraordinary form but The results have been deflando. At the same time, in Audi, the Audi e-tron (then Q8 e-tron) has closed his Plant in Brussels and the shared platform between the Audi Q6 e-tron and the Porsche Macan It has been launched with important delay. But a company has advanced and has been fulfilling without making a lot of noise. That is Skoda, which has had in the Enyaq A really successful electric. Since it was launched, They have delivered more than 200,000 electric cars of the first electric SUV of Skoda. Now, the Czech firm redoubles its bet with the Skoda Elroq, an electric SUV, four and a half meters that will compete in which the most complicated segment of this technology is becoming. Skoda Elorq technical card Skoda Elroq Body type Five -seater SUV Measures and weight 4.49 meters long, 1.89 meters wide and 1.65 meters high. Wheelbase of 2.77 meters. Weight of 1,949 kg. Trunk 470 liters. Maximum power 220 kW (295 hp) WLTP consumption To be confirmed. Expected Autonomies: Skoda Elorq 50: 376 km Skoda Elorq 65: 428 kilometers Skoda Elorq 85 and 85x: 578 and 562 kilometers DGT environmental badge Zero emissions. Driving aids (ADAS) Mandatory by the European Union. Others 5 -inch screen for the instrument box and 13 inches for the central. HEAD-UP Display with the possibility of including augmented reality. Compatible with Android Auto and Apple Carplay by wireless connection. Wireless load of 15 W. Electric hybrid. No. Plug -in hybrid. No. Electric Yes. Useful 52 kWh battery versions (168 hp), 59 KWh Useful (201 CV) and 77 KWH Useful (281 or 295 hp). Price and launch Already available 52 kWh battery: from 34,490 euros (without discounts from the Moves Plan or commercial offers). 60 kWh battery: from 38,390 euros (without discounts from the Moves Plan or commercial offers). 85 kWh battery: from 43,480 euros (without discounts from the Moves Plan or commercial offers). 85x kWh battery: to confirm Born to push sales With the success of Skoda Enyaq behind them and with the promise that the Skoda epyq It will be the great affordable electric car, the Czech firm wants to make this Elroq an electric SUV that adds in a segment that begins to be defined as a great alternative for those who decide to jump into the electric car with a car for everything. In Skoda they define the Elroq as The electric karoq. And that has its advantages. Beyond the immediacy of electric motors or the absence of noise and vibrations, the interior space is really wide. It is a 4.49 -meter long car with 2,765 meters of wheelbase, which guarantees a very wide space for the rear seats. A 470 -liter trunk is added, which guarantees sufficient space for any average family. On the outside, aesthetically, he plays with aggressive and sharp surfaces, evolving the line we already saw in his first electrical model. It surprises its aerodynamic coefficient, which remains at 0.26 cx, which is very good record. A figure achieved by the slightly curved surfaces of its front in which the brand’s identity signs are maintained, such as a particularly muscular hood. Already inside, everything dominates the central screen of 13 inches. It is located in a dashboard that plays with the ways to “take it out” forward. In front of the steering wheel and compared to the central screen, the five -inch instrument box seems tiny. Of course, it has the precise information and you will not miss anything but it is remarkable that its quality is not, from far, that of the central panel that has good resolution and well -chosen colors. The instrument picture is combined with a head-up display that can take advantage of the functions of augmented reality. The panel is bright and reads well in all situations. The indications with augmented reality are good and facilitate the worst navigation I am skeptical with its use on a day -to -day basis, I am not sure that it is not the typical colorful function of which the driver ends up getting tired quickly. The instrument picture looks tiny next to the large central screen but framing it gives it a quality perception that does not have other Volkswagen models. What the Volkswagen group should review is its software. We navigate and sail through its infotainment system and were unable to find something as simple as moving the projection height of the head-up display. A pity in a good quality panel that can give a lot of play. In addition, it forces us to go through the screen to turn off the alarms due to speeding, which is always a bit cumbersome. The steering wheel is simple but their buttons are easy to drive and have the essential minimum. Under the screen there are buttons for rapid air conditioning functions, although the temperature or seat heating remains on the screen, a wireless load of 15 w (refrigerated, good detail) and two USB-C shots. The screen is of good quality but the menus are lioso and it is difficult to find some functions much more than it should. In general, the level of finishes feels good. They are not the most luxurious materials on the market but details as simple as frame the instrument box screen with a small visor already provides a quality perceived superior to that of other Volkswagen models where it is exposed. If we talk about its moving performance, Skoda Elroq is a vehicle that prioritizes, above all, comfort. The direction is soft but does not prevent being accurate when we linked curves on a secondary road. At a quiet and appropriate … Read more

Reaching extreme thinness is the next trend in smartphones. The question is … for what?

by

Samsung Galaxy S25 Edge. This is the most mysterious member of the S25 family, one that comes with extreme thinness as the main ally. After leaking some of his Key specificationseverything indicates that the final thickness of the device will be less than six millimeters. A rather spectacular design in response to a phone that has not yet left (like that is the smartphones market) but that already seems a reality: the iPhone 17 Air. The obsession with extreme thinness will be a trend in 2025. The questions are why and for whom. Samsung has advanced. He iPhone 17 Air It has been rumored for months and with quite consistent information. Except for surprise, Apple will present a new model specifically focused on the thin world. The key is that this will not happen foreseeably until September 2025, and Samsung wanted to advance. In January, together with Samsung Galaxy S25 Ultra, Samsung Galaxy S25+ and Samsung Galaxy S25, advanced the design of the Samsung Galaxy S25 Edge. A thinner phone than the rest of his brothers. But little else. The commitment. Manufacture a extremely thin telephone It has consequences, and they are never positive if we talk about hardware. The leaks tell us about less than 4,000mAh for the S25 Edge, a figure we had without seeing for years. For more miracles that are achieved with optimization, the battery capacity looks very diminished. And this is the main debate and point with thinness: if we prefer a thin mobile with less battery or thicker with plenty of battery. According to the feedback of the xatakers and the mobile requests they usually make, the battery is always a priority. Delgadeness, no. In fact, I remember that after the great reduction of thickness that brought the goodbye of the rounded design (iPhone 11), the rest of the models were growing in thickness and with it, in Mah. He iPhone 14 It was thicker than the iPhone 13and the iPhone 13 was thicker than the iPhone 12. Each and every one of these generations won MAH, and complaints with thinness were … zero. What will happen to the iPhone Air. The Galaxy S25 Edge has had to officially give up a camera, and unofficially (according to leaks) to the battery of his older brothers. The iPhone 17 Air, except for surprise with the implementation of a large-capacity carbon-silege battery, will be a phone with less autonomy than its brothers from the iPhone 17 family. Nor are we clear if it will mount the same camera sensor and Pro lenses of the PRO Models and, if so, Apple will not be easy to continue improving the size of this hardware if the body must be smaller and smaller. In other words, it is currently not possible that two phones, one being thicker than the other, have the same potential at the hardware level. There are battles to be resolved, such as The increasingly durable batteries either The increasingly bright screens But that of increasingly thin mobiles is one, perhaps, inception.
