validates the digital professional card as an accreditation document to practice

by

The highest judicial authority in Mexico has settled a debate that generated some confusion among workers, employers and even institutions: What happens with the digital professional card. Recently have ruled in favor of its validity when presented as the only document, being as valid as the physical one. Below these lines we tell you all the details. Why does it matter? On January 15, the Supreme Court of Justice of the Nation (SCJN) resolved the Contradiction of Criteria 164/2025 and confirmed that the electronic professional card has full legal validity to accredit the beginning of a profession in Mexico. For years it has been a confusing situation in work environments and institutions, even generating unjustified rejections in hiring processes, labor procedures and records. And there were employers and institutions that required physical support out of habit or ignorance, without any legal support to do so. What exactly does the resolution say? The full court established Three points that should be clear: First: the digital ID does not need a photograph or signature to have legal effects, because its function is not to identify a person, but to prove that they are authorized to practice their profession. Second: the electronic format issued by the General Directorate of Professions of the Ministry of Public Education (SEP) meets all current legal requirements, since the regulations at no time impose mandatory physical characteristics for this document. Third: no public or private institution can require the paper version as a condition for hiring or recognizing a professional. Doing so has no legal basis. What this document does not do. However, the SCJN also explained an important nuance that may lead to confusion: the professional ID, whether digital or physical, It is not an official ID. It does not prove identity, only that the person is authorized to start a profession. This means that for procedures that require identification as a person (opening a bank account, voting, signing contracts before a notary…) it will continue to be necessary to present a separate identity document. How to verify its authenticity. If an employer or institution needs to verify that an ID is legitimate, the official mechanism is to consult the ID number directly in the National Registry of Professionalsthe system of the General Directorate of Professions. There is no need to request an additional physical document or request photographs. What changes in practice. For professionals, the ruling eliminates that confusion that has existed for years, since the ID downloaded from the SEP platform It has exactly the same legal weight as any printed version. For recent graduates, it simplifies accreditation procedures and eliminates unnecessary costs and management times. For employers and institutions, the SCJN resolution clarifies doubts and turns the digital document into a mandatory recognition, not an option. Rejecting it or conditioning a contract on having to present the format on paper no longer has legal protection. In Xataka | Mexico has the most powerful dubbing industry in Latin America.

China brought humanoid robots to the country’s biggest television show: it made them practice kung-fu with millimeter precision

by

Every year, hundreds of millions of people in China sit in front of the television to watch the Spring Festival Gala, recognized by the Guinness Book of Records as the most watched annual program on the planet. It is not only a music and dance show, but also a showcase where the country decides what image it wants to project of itself. In this scenario of maximum visibility, the presence of humanoid robots ceases to be a simple technological curiosity and begins to function as a public declaration about the place that innovation occupies in the national narrative. What happened there was not just an artistic number, but a clear clue as to where the Asian giant is looking when it thinks about its technological future. Kung fu, choreography and coordination. To present their robots to millions of spectators, the organizers turned to a deeply recognizable symbol: martial arts. In the CCTV broadcast available on YouTube We can see robots using traditional weapons such as swords and nunchucks, as well as doing tricks and jumping from trampolines, always in sequences shared with human performers. The choice of kung fu provided more than just visual spectacularity, it can also be interpreted as a close way of reading technological advancement within a tradition known to the public. The magnitude of the event. The Spring Festival Gala has been broadcast since 1983 and is an inseparable part of the New Year celebration in hundreds of millions of homes. Reuters also describes it as an event comparable, in terms of media scale, to the American Super Bowl, capable of concentrating popular culture, political message and industrial ambition in a single night. What appears in that scenario entertains and, at the same time, projects a message and indicates priorities. A gateway for the industry. Behind the staging there were specific names and a visible strategy. They participated in the gala companies known in the West such as Unitree, but others less known such as MagicLab, Galbot and Noetix. The immediate precedent helps to understand the moment: Unitree’s robot performance in the previous edition went viral and, in a way, brought this technology closer to the general public. So the idea of ​​betting on a similar show again is reasonable. From the stage to the factory. The public display of these systems fits with a line of industrial policy that places robotics and AI at the center of the next Chinese manufacturing stage. In recent years we have seen how the Asian giant has invested heavily in this sector. According to OmdiaChina accounted for around 90% of the nearly 13,000 humanoid robots shipped worldwide last year, a global shipping metric that does not go unnoticed. Morgan Stanley also projects that Chinese sales could exceed 28,000 units this year, which would point to a notable expansion phase. In Xataka There are people sharing their court cases with AI. The problem is when a judge considers the conversations as evidence In the end, what was seen on that stage went beyond well-executed choreography. Behind each movement appeared a country narrative that combines technological ambition, industrial policy and cultural projection in the same television image. The question is no longer whether these robots can perform in front of millions of people, but rather how much their presence will grow in the coming years and into what spaces of daily life they will end up integrating. For now, its massive presence is destined for this type of spectacle.

There are some that practice ‘partner exchange’ to avoid extinction

by

For decades, popular culture and a certain anthropocentric vision have projected the idea that the traditional family It was the most normal thing in the animal kingdom. However, biology has a habit of contradicting us and if we look Alaskan watersand specifically the belugas From Bristol Bay, monogamy is not only rare: it is evolutionarily inefficient. The study. It has had as its objective analyzing the DNA of hundreds of these cetaceans for more than a decade, and confirms what we could call, in human terms, a lifestyle “swinger” either polyamorous among these animals. Although this word is more for our daily life, since in a scientific way it is called polygynandryand it is the secret of these whales to stay genetically healthy and resilient. The myth of the “better half”. Choosing a life partner for whales is something that is not the norm in this case. To reach this conclusion, the researchers They didn’t just watch what they did.but carried out an exhaustive analysis of 623 genetic samples collected over 13 years in the Bristol Bay beluga population. And we are facing a very interesting population because it is geographically isolated and has about 2,000 individuals. What they found was a mating system where both males and females mate with multiple partners. There is no “alpha male” that monopolizes females (polygyny), nor females that have only one consort. It is a constant and strategic exchange. Stepbrothers everywhere. The definitive proof of this behavior is in the family trees that the study managed to reconstruct. When analyzing kinship, scientists came across a revealing fact: there were many half-siblings who shared a mother or father but not both. The fact that it is very difficult to find full siblings indicates that season after season, females do not repeat partners, but rather change. A strategy that is aimed at maximizing reproductive success, since otherwise a few males would dominate the genetics and cause less genetic diversity. ‘Swinger’ as an advantage. We might think that this behavior is chaotic, but it is actually a very sophisticated biological defense mechanism. And constantly mixing genes with different partners ensures greater variability in the offspring to avoid serious diseases such as those that historically occurred. we have had in the European monarchies. But the interesting thing is that it is a choice of the females who play an active role. In this case they are not passive, but actively choose the males to mate with to have great variability, possibly to ensure that their offspring have the best possible genetic combinations. Its longevity. One of the characteristics of this species is that it can last for many years, and that is why maintaining genetic diversity through polygynandry allows them to adapt to long-term changes in their ecosystem. And it is a finding that aligns with previous research, since a high diversity in the microbiome and population structure of these whales was already pointed out, but the mating system had never been confirmed. A genetic lifesaver. The most fascinating thing about this discovery is how it rewrites our understanding of cetacean sociality. We often assume that highly intelligent and social animals tend toward monogamy (as is the case with certain birds), but the reality is that belugas demonstrate that you can have a complex society, care for offspring, and at the same time have a promiscuous sex life for the good of the species. For conservationists, this is good news. Knowing that this population maintains high genetic diversity and avoids inbreeding itself means that they have better biological tools to cope with climate change and human pressure than other more “faithful” but genetically poorer species.

What is and how your “practice” option works to help you learn languages

by

Let’s explain what it is The new function Practice of Google translatorwith which the app aims to compete with Duolingo and other tools to learn languages. It is a new evolutionary leap fed by artificial intelligence, and that gradually comes to some users. We are going to start the article explaining what this tool is to know its concept. Then, we will explain in a simple way the basis of its operation. What is the way Practice of Google Translate The Google translator is an application with several functions. The main one is that you write one thing and the app translates it into other languages, but over time functions have been added such as translating the text of an image or translating a conversation between two different languages. Practice is a new function that is beginning to arrive To the application. It is a button inside the app, just like using the camera or entering the conversation mode. And its goal is to help you practice a language. This option allows you practice a language with real language and daily usejust what you would need to establish a conversation with someone. Of course, the application will not teach you from scratch, and you will need to have a basic knowledge of the language to start perfecting it. Although in the future they will add the possibility of learning from scratch. The Google translator It will generate personalized lessons with artificial intelligence depending on the needs you have. Come on, you tell him what context you want to learn, and lessons will be shown to practice the language. The function of Practice It has not yet reached all usersand will do it little by little for the next few weeks and months. The normal thing is that you do not have it yet, so if you are looking forward to trying it you will have to look every time the app is updated. How to use this mode The first thing you have to do is enter the application of the Google translator, and configure it to translate texts of the language you want. For example, if you want to practice English, configure the app to be the language from which you make a Spanish translation. Now, click on the button Practice that will appear below at all if you have the function activated. This will take you to a screen where You must say what motivates you to learn The language. Here, you will have to say What is your goalif you want to learn the language to travel, to work or chat with friends or family. This will cause lessons to adapt to this context. After writing this, click on Start practice. This will take you to a screen where you will see Several cards with recommended situations optionseach of them with a different practice. It can be a practice of confirming keys of a reservation, or another situation based on the needs you have set up before. Choose the card you want and click on the button Practice. When you press on the practice button on one of the options, you will go to the lesson. Here, you will see that Each lesson has several exercisesbeing able to listen and understanding what you tell you or saying something with your voice in a conversation. If you get stuck, the app will offer clues when you don’t know what to say. In the exercises we talk, the Google translator will recognize what you say, even if you pronounce things slowly or clumsy. There are also other exercises from other styles, such as Recognize words in phrases you hearand much more. And if there is something that does not convince you, you can generate the exercises again.

How to practice languages ​​using artificial intelligence

by

Let’s tell you several ways in which you can Practicing languages ​​using artificial intelligence. These are several resources that you can use to improve your knowledge of the language, something for which you can use conventional AI models such as Chatgpt, COPILOT, Deepseek either Gemini among others, although at some point we will mention another tool of artificial intelligence. We are going to divide the article into several points, each of which is A different method to learn English. We do so because the needs of each person can vary, and it is not the same to want to practice a conversation than to test your knowledge or correct a writing. Use simulated conversations The first method is the simplest, You can tell Chatgpt to hold simulated conversations to make an exchange of messages in the language you decide. This will help you maintain daily or specific conversations for erales, and thus improve your fluidity speaking You can start with a Prompt as “Hello, act as a waiter in Paris. I want to practice how to ask for food in French.”and then start the exchange. Then you can also ask you to make grammatical corrections or suggestions to have more naturalness. Ask the AI ​​to correct a text Another thing you can do is write a text in the language you want. Then, You ask the AI ​​to make a correction To find errors. You can ask for it with a prompt like this: “I’m going to send you a text, and I want you to make me spelling and grammatical corrections, explaining the mistakes that there are. Also give me style suggestions so that it seems more natural,”. The thing is to write that request in Chatgpt, Gemini or a similar artificial intelligence, and when I tell you that you agree, that you hit the text, then you fight it whole and send it to it as if it were a message. The AI ​​will generate a list of errors and corrections well explained. You can do this even to improve your native language when writing. A bonus track is that you can Use extensions for computer or browser that correct errors based on artificial intelligence. The most important and reliable is that of DEPLa famous popular translator for being much better than Google’s, and who has applications for Windows and Mac, and also extensions that indicate when you write a text the mistakes you are making. Have spoken conversations Many AI chats already have free functions to maintain voice conversations, so that you listen to what you say and then answer. You can also do this to try Maintain a conversation in another languageasking him to make you corrections of your mistakes. For that, you can start the voice conversation by telling you something like “You are going to be my English teacher, and we will have a casual conversation in this language. But when I make a grammatical error you have to explain in Spanish”. And after this, just start talking. Ask for help with words and vocabulary You can simply ask the AI How are concrete words or phrases say In the language you want, one of the simplest aids. And then, the artificial intelligence bot will answer you and give you an explanation of possible meanings. You can also ask you to create a list and vocabulary for concrete issues, such as trips, businesses, meals, and so on. Thus, you can learn new words in the language you want. Ask for translations with explanation When you want to translate a topic, it is easy for you to simply turn to an ordinary translator and hit the result that gives you. However, you can also ask the AI ​​to do A translation with grammatical explanations. Something like “I want you to translate the text that I am going to hit you to English, and add grammatical explanations and comparisons of structures between the two languages.”. Something like that will give you a much more didactic translation. You can also ask you to make more natural alternative translations, or after the translation ask you to explain why you have translated certain phrase in such a way. Come on, you can level translations To learn language things in the process. Ask for a curriculum “I want to start learning English from scratch, and I would like you to do a study plan adapted at the beginner level, with resources recommendations.”. Only with such a prompt, AI can help you organize a study process by offering resources. Ask for exercises and exams Finally, You can ask you to do exams To test. You can do this in different ways: you can ask you to generate the template of an exam, or you can ask you to tell you questions of an exam and correct your answers. You can also ask for loose exercises, that ask you several questions several related to a theme. In any case, it is important that you specify THE EXAM AND LANGUAGE LEVELin addition to mentioning whether you want to do it on concrete topics or concentrate on environments or types of conversation. You can also specify that it is grammatical, spelling, or whatever you want. You can also ask you to generate games to learn languages By way of exercise, such as hanged, where you have to say letters and guess the word before making a certain number of mistakes.

To survive in Europe, our Paleolithic ancestors turned to an extreme practice: cannibalism

by

More and more evidence is that our ancestors resorted, at least occasionally, to cannibalism. We are not speaking in this case of other human species, such as Neanderthals, who could have practiced dozens or hundreds of thousands of years but also Homo sapiensthat had already become the only humans in Europe and the rest of the world. New tests. A recent study led by researchers from the Catalan Institut of Human Paleoecology and Social Evolved (IPHES-CERCA) He has shown New indications of cannibalism among humans. They found them in the Polish site of the Maszycka cave, whose remains would go back about 18,000 years ago. Europe in the Magdaleniense. This places the finding in the context of the Magdalenian period in Europe. This period that owes its name to the French site of the Madeleine covers various European settlements between 19,000 and 14,000 years old, they explain in An article for The conversation Some of the members of the study responsible for the study: Francesc Marginedas Miró, Antonio Rodriguez-Hidalgo and Palmira Saladié Ballesté, researchers from the IPHES-CERCA and CSIC. The period follows an era of important changes in Europe, mainly derived from the end of the last era era. The ice setback left behind an ideal environment for a change in ecosystems, and with it the expansion to the north of modern humans. From burial to the table. As the team continues, the Magdaleniense, to others of his cave paintings, also stands out for careful funeral rites, burials “with care and offerings”, at least for some of his dead. Because to others what expected them was the flint of the tools with which they were expired. 63 bones. The new analysis studied more than fifty remains found in the Polish Cave of Maszycka, located near Cracovia. They belonged to half a dozen individuals, both adults and children. The remains found together with animal remains and many with signs of having been manipulated. Despite this, the hypothesis that this manipulation responded to simple funeral rites had not been ruled out. The new analysis has incorporated new 3D microscopy techniques in the study of brands, which has allowed distinguishing brands caused by humans from others, such as those that would have caused other carnivores. “The location and frequency of cutting marks and intentional fracturing in skelet added in a press release Marginedas. The details of the work were published In an article In the magazine Scientific Reports. To the core. The study revealed other details that can give us some clues of the context in which this consumption of human flesh was produced. For example, the team points out, the bodies were prosecuted shortly after death, thus avoiding the decomposition of tissues.
