The control of the “blue line”

by

About a week ago it began to appear in specialized media a war legend that is repeated from time to time: the United States has a kind of Offer switch of the artillery that sells to the rest of the planet. The virality of the story was such that Washington has had to go out. Faced with lose miles of dollars now that Europe Talk about rearmathe nation has denied having something similar to that button in its F-35. The reality is that it does, although otherwise. Europe and the exclusion of the US. To understand why the rhetoric of a hunt is important we must expand the geopolitical map. The European Union has launched the ambitious plan “European Defense Readiness 2030”With the aim of strengthening its defense autonomy, and does so through a significant Increased military spending and a drastic expansion of its industrial capacity to produce local weapons. The initiative arises in a context of growing distrust of the United States, motivated by the signs of a strategic distancing from Europe, the volatility in the supply of weapons and the Trump decisions They have generated alarm among the allies. No doubt, this European turn towards arms protectionism could leave the United States out of billions of dollars in weapons sales contracts, as the new scheme exclusively prioritizes EU member countries and certain close partners, explicitly excluding both the United States and the United Kingdom. Ukraine turned on the fuse. The decision is influenced, among other things, by the abrupt arms and intelligence towards Ukraine during Trump’s mandate, which has generated concerns about the reliability of the American commitment. But there are more, since many of The reports that they have been moving these weeks have generated alarm by suggesting that the United States could have the ability to remotely deactivate armament high -tech as The F-35a fear fed by the operational dependence of these systems regarding the logistics, maintenance and software networks controlled by US contractors. The “truth” of F-35. We tell it A week agobut we are going to expand the abilities that the United States has on the functions of the hunt. Both the Pentagon and Lockheed Martin herself They have categorically denied The existence of A “Kill Switch” (off button) in the F-35 that allows to deactivate it remotely, however, the operational reality of the system equivalent functionally to the same. The F-35 global supply chain in 2018 (important: Turkish companies are currently not participating in the program) As? The logistics structure, maintenance requirements and, above all, proprietary software dependence It makes no country fully operate the F-35 without the constant support of the United States. This restlessness, which began as a rumor in defense circles, has climbed to such an extent that the F-35 Joint Program (JPO) and Lockheed Martin were forced to Issue official statements To placate international concern, stating that all operators have the necessary capacities thanks to “well established agreements.” Again, these statements undoluntarily underline The central problem: The plane is not autonomous for those who buy it, and it only flies if the United States wants to do so. A closed and controlled ecosystem. The F-35 is not just a combat plane, but a PSophisticated software canoformhighly dependent on a global support network controlled from the United States. Its operation It depends on systems such as Alis (Autonomic Logistics Information System) and its successor Odin (Operational Data Integrated Network), tools that not only manage maintenance and logistics, but also handle Critical information such as the Mission Data Files (MDF). It is not a trivial theme. These files define from threat parameters to detection flight routesthrough the fusion of sensors and the electronic war. To get an idea, if a country loses access to Odin or stop receiving updates from its MDF, the F-35 remains practically useless or severely degraded in their operational capabilities. This makes any buyer the closest to a technological hostage of the United States unable to maintain total control of their fleet. The perfect example is understood with the so -called “blue line.” The blue line. As we said, that “data package” of missions planning is a key factor for the survival of F-35. In fact, all this translates into a control of the called as “blue line” (The aircraft route to an enemy zone) projected by the system, which is based on the combination of numerous factorsfrom enemy air defense bubbles to the capabilities of stealth and electronic warfare of the aircraft, as well as the sensors and armaments on board, and the tactics integrated between the F-35 and other assets. It is, at least, one of the most powerful weapons of the F-35, possibly the one that most. In other words, without the absolute control of the blue line, the combat plane and its pilot have little to do when they reach enemy areas, becoming vulnerable to detection and demolition. A system designed for independence. All this leads us to a very simple simile. The logic behind the design of the F-35 is comparable to that of technological products such as the iPhone or the Tesla: complex, closed systems, whose repair or update is deliberately centralized. This implies that every time a critical component is damaged or an update is required, it is necessary resort to US contractors or personnel trained under American standards. In addition, the supply chain involves more than 1,400 suppliers throughout the nation And only 80 in other eleven countries, which demonstrates the absolute dominance of the American industry over the product, even in its exported versions. Billions at stake. With this map of the hunt we can get an idea of ​​the importance of the “trust” of the buyers. In essence, an authentic Fortuna for Washington in a global geopolitical context as unstable as unpredictable. Plus: Donald Trump’s choice, his antiglobalist rhetoric and his questioning of alliances such as NATO aggravated distrust. Governments begin to ask how sure their investment in a system that cannot be completely controlled and … Read more

Free remote access disappears after a decade and takes a worrying turn for its users

by

Plex has announced which will increase the price of your subscriptions and make your main free function into payment service: remote reproduction of personal content. The changes will take effect on April 29, marking the end of an era for millions of users who used the platform to access their multimedia libraries from anywhere without having to pay for it. Why is it important. This decision directly affects millions of users who have built domestic ecosystems based on the premise of being able to access their personal content from any location. The changes represent a total turn in the business model of Plex. The figures. Price increase is considerable: Monthly subscription: from $ 4.99 to $ 6.99 (+40%). Annual subscription: from $ 39.99 at $ 69.99 (+75%). Vitalicia subscription: from $ 119.99 to $ 249.99 (+108%). It is easy to read between the lines what Plex intends with these different increases: to promote the monthly to increase their monthly recurring income … and dissuade the life, or at least monetize it much more aggressive. There are alternatives. For those who see a reason here to migrate from Plex: Jellyfinopen and free source, without payment or telemetry functions. Embyversatile without too much complexity, with a free version robust. Kodiveteran customization. Stremiofocused on streaming from different sources. The current situation. Until now, Plex allowed its users to configure a domestic server and remotely access its content for free. This model has been the basis of the growth of the platform for more than a decade, which has become tremendously popular. The change. As of April 29, you will have two options if you want to continue accessing your remote content: That the server owner has a plex pass. In this case, all users who give access can continue to see content remotely. Hire the new “Remote Watch Pass” for $ 1.99 per month or 19.99 a year, which allows remotely accessing servers whose owners do not have plex pass. Between the lines. Plex justifies these changes alleging “growing costs” and the need to continue developing new functions. However, the decision comes at a time when they want to position themselves as a legitimate competitor in the saturated streaming market. The company has been incorporating new social and discovery functions during the last year, in addition to launching A store to rent movies and series. These movements are subtle signs of a strategy to become a complete streaming platform, beyond its original function as a personal media manager. As compensation, Plex will eliminate the limitation of one minute reproduction in its mobile applications and it will no longer be necessary to pay a unique activation fee to eliminate this restriction. And now what? If you are a plex user, you have until April 29 to buy a life subscription at the current price of $ 119.99, before it doubles. The current monthly and annual subscribers will see their rates increase, while those who already have a life subscription will not be affected. Content streaming in the same local network will remain free, as well as access to content with advertising offered by the platform.

After triumphing with its chips for AI, Nvidia has set another disruptive technology: quantum computers

by

Nvidia’s bet for Quantum computers It is less and less shy. Jensen Huang, the co -founder and general director of this company, has announced A few hours ago at its annual developer conference that will open a laboratory expressly dedicated to Quantum computing research. It will be housed in Boston (Massachusetts) and will allow NVIDIA engineers to work side by side with the researchers at Harvard University and the Massachusetts Technology Institute (MIT). It will begin operating at the end of 2025. This strategic movement puts on the table with absolute clarity that Huang does not want to stay out of technology that will presumably cause a medium -term disruption. The most curious thing is that before formalizing the implementation of its new quantum technologies development laboratory, this executive has not let out the opportunity to retract. At the beginning of last January A few statements They caused a very abrupt fall of the actions of some of the companies that are dedicated to the development of quantum computers. “If you said 15 years you would probably be optimistic. And if you said 30 you would be pessimistic. But if you opt for 20 years I think many of us would believe it,” Jensen Huang argued At that time. With this reflection I tried to predict when the really useful quantum machines will be ready, and, therefore, capable of dealing with a very wide range of problems. But he has changed his mind. Just two and a half months later seems to be convinced that fully functional quantum computers will be ready much earlier. With the correction of errors of quantum computers in the spotlight Nvidia flirting with quantum computers is not really new. And is that He has been collaborating for more than two years With the Israeli company Quantum Machines. This company specialized in the development of hardware and software for quantum machines, and has been ready with NVIDIA a low -performance and high performance architecture that seeks to promote the progress of quantum computing. DGX quantum seeks to help researchers who work in the field of quantum computing to develop new quantum algorithms NVIDIA has contributed its CPU/GPU grace hopper system, a beast that is designed to execute applications of artificial intelligence and offer productivity at high performance computer scenarios, and also its open source programming model CUDA QUANTUM. His partner in this project, Quantum Machines, has been in charge of the integration and set -up of a quantum platform that, according to these two companies, is specifically designed to work in hybrid systems in which classical hardware and quantum coexist in harmony. The purpose of the DGX Quantum platform, which is what is called the hardware that these two companies have developed, is to help researchers who work in the field of quantum computing to develop new quantum algorithms. It may seem surprising that it is possible to use classic hardware to develop quantum algorithms, but it is something perfectly viable. In fact, this strategy helps to put quantum computing within the reach of many more researchers who can implement and test their ideas without having access to a quantum computer prototype. However, the DGX quantum platform also serves, according to NVIDIA, to calibrate quantum systems, control them, and even aspires to have a prominent role in the tuning of a correction system that allows quantum computers amend your own mistakes. Jensen Huang emphasized this idea during his GTC 2023 conference, and there is no doubt that It is a very attractive possibility. Extraordinarily attractive. And is that, As Ignacio Cirac explained to us In the conversation we had with him, the correction of errors will give us the opportunity to solve with quantum computers really significant problems.

We believed that creatine was one of the most useful supplements to gain muscle mass. We are no longer so sure

by

Creatine is an old acquaintance of people who exercise in order to increase muscle. Evaluate in our own meat the effectiveness of a supplement is useless, especially because we surely accompany it with a strict exercise regime that will prevent us from distinguishing its net impact. That is why, if we ask ourselves to what extent the creatine works, we need to study it rigorously. Not so effective. And the verdict of the last study that has tested this substance It has not been favorable. In a study that included a 12 -week training program and the consumption of 5 grams daily of creatine supplement were not observed relevant differences between those who took the substance and those who did not. “We have shown that taking five grams of creatine supplement per day does not make any difference in the amount of muscle mass that people earn when performing resistance training,” explained in a press release Mandy Hagstrom, co -author of the study. “The benefits of creatine could have been overestimated in the past due to methodological problems,” the researcher adds Creatine. Creatine, or α-methyl guanido-acetic acidit is a compound that can be found naturally in our body, especially in the muscles and cells of our nervous system; And also in some foods, such as red meat, fish and shellfish. Creatine molecules are formed from three amino acids and Stores phosphocreatinemainly in the muscles. There is used as a source of energy. That is why the creatine supplement is used to obtain better results when exercising and gaining muscle mass. 54 participants. The recommended maintenance dose of this supplement is between three and five grams per day. The 54 study participants, aged between 18 and 50, were divided into two groups, some would begin to take five grams Creatine Monohydrate (CRM) first and a week later they would start a 12 -week resistance program. The second group would also face this exercise program, but without the supplement. The food of both groups was monitored to verify that there were no relevant differences in their diet. Both groups increased their muscle mass, but they did it in a similar way, about two kilos won during the period. The details of the study were Published in an article In the magazine Nutrients. The problem is in the water. Part of the study key is in time: that the experimental group (the one who took the supplement) began this “treatment” before training allowed the team to test (and verify) a hypothesis, that a part of the muscle increase that we associate with creatine is due to a greater water retention. The team observed that, during this first week, indeed, the group (and especially women in this) began to gain muscle mass, a 0.5 kg difference that dissipated after starting training. Hagstrom pointed out, of course, that more studies are still necessary to understand the impact of water retention associated with the consumption of this supplement. Dose question? The study responsible for the study suggests that, in addition to water retention, the chosen dose could also have had effect on the results. The five grams daily represent the upper limit of the recommended daily maintenance dose, but those who consume This supplement They often resort to a “load phase” that implies consumption between 20 and 25 grams of the supplement per day. This possibility was discarded by the equipment since these consumption levels, they explain, can cause gastrointestinal problems and is not necessary to achieve saturation levels. However, they affect the need to carry out additional studies with intermediate doses, for example of 10 grams. They also point out that longer -term studies could help us better understand the impact of creatine supplements on the increase in muscle mass.

Universal will do the competition to Disneyland with Harry Potter and Mario. Disney will counteratacious “turbo-charging” its parks

by

In its annual meeting with shareholders, the Disney CEO of Bob Iger has made ads that cover the entire empire of the producer: of sequelae for its animated franchises to plans for its attraction parks. It is the conducive moment: the competition will be more at odd than ever, especially now that it arrives Epic Universe de Universal To Orlando. Old acquaintances in attractions mode. In the ads that Iger has shared, he has talked about attractions inspired by ‘Cars’,’Avatar‘,’The lion king‘,’ Monsters SA ‘,’ Coco ‘and many other franchises. With this, they set the planned plans of Disney, which in autumn of 2023 announced that it was going to fold the investment in thematic parks: The producer would be spent in this sector that, together with the cruises, is what most benefits the brand, $ 60 billion in the course of a decade. An ambitious plan to spab from the experience section, which Nor is it working as it should. The turbo-carga. This has been defined by Iger himself: “Last year we talked about our plans to boost growth in this segment through strategic investments.” And he continues: “Right now, we have more projects in progress throughout the world than at any other time. Magic Kingdom is experiencing the greatest expansion of its history, with a new area inspired by ‘Cars’ and the expected theme park of the villains. And a thematic area of ​​’Monsters SA’. It will reach Hollywood Studios.” And the lion king, to Paris. To all this are added attractions of ‘charm’ and Indiana Jones in Animal Kingdom. And in California Adventure, new attractions of avengers (the area dedicated to the Marvel heroes will bend their size), ‘Avatar’ and ‘Coco’. Disneyland Paris will arrive the first attraction dedicated to ‘The Lion King’, which will be aquatic and that will accompany Simba on his trip to become king. Some of them already advanced Disney in the past D23, where detailed what would consist Many of these attractions. The competition: Epic Universe. In Disney they are in crisis policy because on May 22, Universal will open in Orlando Epic Universe. It is a theme park divided into five universes, some of them as attractive to the general public as Harry Potter or the outside of Japan version of Super Nintendo World. They will join the Dark Universe, based on the company’s classic monsters, Celestial World and its science fiction and fantasy setting, and another area about ‘How to train your dragon’, which Universal wants to turn into one of its star franchises with the premiere of the real image film. And the rest? Regular, thanks. Being one of the companies dedicated to entertainment more powerful and influential of the moment, and with Well sanitized accounts (especially if we compare them with Warner)we are far from being able to say that Disney is in crisis. But this annual meeting with shareholders has been revealing: before all the news related to the parks, only some sequelae and new animation films have been presented, Like ‘Coco 2’they have not awakened too much enthusiasm. Safe Baza. To this is added that Marvel spends complicated moments: Captain America’s last movie is already one of those who have had Less collection of the MCU Hster. At a time, it is clear that Disney should cover several fronts … and re -bet for a safe trick: the multimillionaire parks business.

Only one of them enjoyed the experience

Running out of wifi or no data connection is one of the worst nightmares for generation Z, since it is the first that has grown in A 100% digital environment. However, the Milllenials and, above all, the members of generation X, have lived part of their lives without current hyperconnectivity. Although it seems crazy, A group of editors of Good Housekeeping He decided to return to those times when the smartphone was not the center of everything and, paradoxically, it was used to call or, at most, to send messages on SMS. The reason? Escape from constant Notification bombardmentsocial networks and the feeling of always “connected”, making your brain detoxify the negative effects of the constant “Infinite Scroll“That predominates in applications installed in smartphones. The challenge: one week without smartphone The idea arose after verifying Digital detoxification need In a world where mobile dependence is almost inevitable. Google Maps to get to the sites without losing us, listen to music or podcast in dead times or be in constant communication with dozens of people at the same time with WhatsApp groups. The protagonist of the article, a millennial addicted to WhatsApp groups, proposed the challenge to her co -workers of different generations: spend a full week with a “Dumb Phone”, such as those used in the 90s and 2000. The response was well received by the participants and many were interested in the experience of disconnecting from the slavery of notifications and Tyranny the Fomo. The only one but found the idea was that the need to stay tied to technology for labor and personal demands. To carry out the experiment, some phones got Basic Nokiafamous for its lasting battery and simplicity. Thus, a Millennial, a member of the X generation and a young woman from the Z generation Zambuller in the “digital disconnection” and did it without float. They did not even make a dump of the agenda, so they could only call those numbers that they remembered or who were getting. X Generation: A Way Without Return Those of us who belong to generation X, more than digital natives, have been digital migrants. That is, we have grown a good part of our life with hardly any technology, but we have been its Inventors and “Early Adopters” that has risen to all the trains of its evolution. Therefore, it is a generation that has become accustomed to technology, but it has not been as dependent as millennials or the Z generation, because it has already lived in a world without WhatsApp, GPS or Spotify. However, the experience was bittersweet. On the one hand, Simon Swift, the editor of the X generation that did the test, claimed to have enjoyed the tranquility of Read a journal to workavoiding negative information overload. That allowed him to reconnect with the real world. However, the difficulty of communicating through text messages and the dependence of physical maps (the bad view, already touched by the years) were frustrating. In addition, the impossibility of playing Classic “Snake” Due to the “too fat” fingers it was a hard blow to nostalgia. “I like to connect with the world around me. In such a dynamic and unprecedented news period, I want to know what is happening. I don’t think I can re -educate my brain In that sense, “said Swift. When honey is proven, it is difficult to give up the candy. Millennials: between the fomo and the return to be productive Florence Reeves-White was the ideologist of the test and the millennial representative in this experience. He confessed to feel panic at the idea of ​​missing important conversations in the chat groups of his friends or not being aware of the latest news. However, the experience turned out to be more positive than expected. Having access to social networks, its productivity increased, dedicating more time to writing, reading and performing activities that really enriched it. In addition, not being constantly communicated with their partner or not having distractions in the dead times, voice conversations with their family and loved ones became more common, creating a different link. Again, as happened to the representative of generation X, the lack of fitness, maps or the impossibility of paying with the mobile, generated inconveniences in their day to day, but the feeling of improve your productivity He has marked this participant who will not hesitate to repeat the experience, although with some nuances. Z generation: This is what they call life? For the representative of the Z generation, it was called Megan Geall, a digital native and intensive user of the smartphone for absolutely everything, the disconnection It was a real challenge. One of the first effects he noticed was that of full attention while seeing a series of Netflix at home. I no longer had the temptation to review social networks while watching the series. The impossibility of accessing social networks also meant a breeze of fresh air in this experience: “It was very nice to be disconnected for a while and not see what others do with their lives, simply live mine,” said the young woman. However, limited options for entertainment and communication of the Dumb Phone who was using some inconveniences. The difficulty in writing text messages, the lack of music in the gym and the impossibility of using Apple Pay were the main obstacles. Despite recognizing some benefits, such as a greater connection with people by having to call them by phone Instead of sending messagesThe young woman concluded that she was not willing to give up the comfort provided by her smartphone.

There are a lot of time apps. Know which one that is most accurate is almost impossible

by

You get up one morning. You look at the application of time on your phone. “100% rain,” or so says. You go to the window and there is a scorching sun illuminating the street. Worse is to consult the application of time, that just 10 or 20% probability of rain and, as soon as you leave, you fall a downpour. The latter is what It has been happening in Spain during the month of Marchone of The rainiest in a long time. Although we blame apps not to predict perfectly, the truth is that interpreting them is not as easy as it seems. How time apps work. Time applications work by combining data from different meteorological models to show us what are the rain forecasts for that day. Each of them is based on a different model, depending on the company behind. These models can be global or regional, having the latter more precision in specific areas. In Spain, Aemet operates with different models such as Arome, MM5 or Reion, although time apps can use models outside our country. Apple and Android. Apple’s time app uses information collected by The Weather Channelsince it has Your own API to provide meteorological data to other apps. If we use an android, such as an Xiaomi, your app works with information from Accuweather. This is precisely what makes each app show us a different fact: each of them is based on the models that it considers, and make predictions on their own. For example, use your own prediction system called Accuweather Minutecast, which combines numerical models with artificial intelligence and real -time radar data to offer hyperlocal forecasts. It does not generate its own weather models from scratch, process information from global models. 100% rain. One of the main problems in the time apps has to do with how they show the information to the user. If we see 70% in the app, probably, let’s understand that the probability of raining in our city is 70%, something that is not completely. In fact, the thing is even more complicated if we go to the forecast for hours and there we see that the percentages are lower than those of the total day. Quite difficult. We start from the basis that the weather prediction It is a complex science due to the dynamic and chaotic nature of the Earth’s atmosphere. Factors such as sudden changes in temperature, pressure, humidity, wind patterns and ocean currents interact intricately, creating a network of interconnected processes difficult to foresee exactly. What is “100%”. There is a common common interpretation with respect to the percentage of probability of rain showing weather applications. It is easy to think that a “100% rain” indicates that it will rain throughout the day throughout the area. The truth is that this 100% means that, in similar weather conditions, it has rained 10 out of 10 times. But it is possible that this new occasion does not do it. The percentage does not determine the rain that will fall, but the statistical mark of how frequent it has been raining in similar conditions. The best way to measure it. The time apps have these limitations, and so they will continue to be until the meteorological measurement system changes. Something that will not happen in the short term. That is why in recent years there is a very booming app: rain radar. Unlike traditional time apps, Rain Alarm is an app that is based on real -time radar data. These radar models do not work in the long term: they use data to make predictions in almost immediate ranges. This is why, with just opening the radar app, we can observe much more precisely the state of the atmosphere. Today, this is the most accurate way of knowing immediately how the weather will behave. And, still, it will still not be accurate. Image | ECMWF In Xataka | Aemet already knows when the storm that is soaking Spain is over. The problem is that another act comes another

They will arrive at hundreds of households this year

There has been a promise that humanoid robots will arrive at our homes to accompany us on a day -to -day basis. For now, the closest thing to what we have are the robotic vacuners, which operate autonomously and are already present in many houses, although they have a lot of robots and absolutely nothing humanoid. Now something begins to change. The Norwegian Startup 1x, backed by OpenAI, has announced that this year will send its humanoid robot neo gamma to “a few hundred or a few thousand” of real homes. His CEO, Bernt Børnich, has confirmed it, In an interview with Techcrunch During the Nvidia GTC 2025 event, where robotics was an absolute protagonist. In the same event, Jensen Huang, CEO of Nvidia, presented a series of ads related to artificial intelligence and robotics. From the laboratory to the living room: a test that is not less. It will not be a commercial launch. Nor is a completely autonomous experience. Neo gamma It will arrive as part of a trial program, still under human control. It will be teleoperated by specialized personnel, who will guide him from remote centers while 1x observes and collects data. But that does not detract from it: it is one of the first attempts to carry a humanoid robot with human form and domestic aspirations to a real home. For Børnich, it is a fundamental step: “We want me to live and learn among people,” he said. The company seeks to understand how the robot reacts in a daily environment, how it adapts to real -life dynamics. The data collected will serve to train their artificial intelligence models, developed internally, despite OpenAi’s technological support. A robot designed to live together: soft design, silent movements. Neo Gamma avoids the appearance of an industrial robot. Instead of exposing cables, gears and metal structures, we wear a clear suit that conceals its mechanics and gives it a closer and less intimidating look. Its design seeks to fit home without disregarding, moving away from cold and mechanical aesthetics that usually accompanies humanoid robots. It is designed to help in domestic tasks, such as ordering, cleaning, taking care of the routine so that humans can devote their time to other things. His hands are designed to manipulate objects with precision and care. His movements, according to 1x, are silent and safe, away from the typical buzz or robotic rattle. In addition, it is equipped with a battery of sensors, cameras and microphones that allow you to read your environment in real time. Robotics enters home. And with her, new questions. All progress entails new questions. And in this case, many revolve around privacy. Although the remote control will presumably be regulated by the terms of the service, it is still a person, on the other side of the connection, which will be seeing and listening to what happens inside the home. It is not a minor detail, and those who participate in the test should be fully aware of it.

Now the app has given them more control over their children’s accounts

by

Tiktok has established itself as una of the most popular applications Among adolescents. Although it is presented as a harmless platform, Full of dancessongs and Life Hacksmore and more voices warn about their possible negative effects on the youngest. Some studies point to an increase in cases of depression and eating disorders, while many parents They express their concern for the time their children spend doing Scroll non-stopneglecting other activities of your day to day. New tools for parents. The Tiktok social network, owned by the Chinese firm Bytedance, has announced New functions aimed at better protecting adolescents. These include the possibility that parents or guardians establish daily and customizable time limits. For example, it is possible to configure a maximum of 30 minutes during the week and expand that time during the weekend. Once the limit is reached, the application will be blocked automatically, and can only be unlocked with a code held by the responsible adult. 11 tricks to dominate Tik tok These tools not only allow to adjust the time of use to each specific case, but also offer parents the option to block the app at any time: during a family meal, school hours or when they consider it appropriate. In addition, they can see who follows their children, who are still and who has blocked them. Soon, the company states, a function will also be enabled so that adolescents can notify their parents every time they denounce a content they consider inappropriate. Parental Control in Tiktok: How to activate new tools for parents. Once the parental control tools are known, many parents will want to know how to activate them to manage the use that your children make of Tiktok. The process is not complicated and only requires fulfilling some basic steps. The first thing is that the father or legal guardian must have a Tiktok account. From there, you must enter your profile (below right), touch the three -line menu icon and access Settings and privacy. Within that section you will find the section Family synchronization. Tiktok will ask if it is the legal tutor. If the child has his mobile by hand, just scan a QR code from that device. If not, you can send an invitation through WhatsApp, Instagram, text messages or any other channel. Once sent, there are 48 hours to accept the link and complete the link. When both accounts are synchronized, the adult, in addition to those mentioned, may establish daily limits of use, control who can contact the minor and decide whether their account is public or private. The above tools. As we said, Tiktok has already launched the new parental control tools in much of the world. However, the users themselves, including adolescents, already had some control options for a long time. Among them stands out the function Time on screenwhich allows you to establish pauses in the use of the FEED of videos and configure reminders to go to sleep. These options can be activated from Settings and privacy > Time on screen. Images | Tiktok In Xataka | The videos of AI have broken the Instagram and Tiktok algorithms.

135,000 years ago, humans had developed a key component of universal culture: language

by

A way of thinking about thousands of languages ​​spoken by humanity is visualizing them as branches of a tree, thus drawing The evolution of these languages over time. If we move forward in time, we will see the diversification of some languages ​​and the death of others. If we invest the time needle we can see the branch or the common trunk that joins some languages ​​with others. For example, if we draw the history of Galician and Romanian, we will see in Latin the common origin of these languages ​​spoken in remote areas of Europe. We can do the same exercise looking for the common trunk between Latin and the Swedish. For this we would have to go to prehistoric times, to a common trunk we call protoindoeuropeo And what would have been spoken Around 5,000 years. However, this does not serve to unite all the languages ​​spoken by humanity in the same tree. We do not know of a link that one languages ​​native to the Americas, the languages ​​of Asia and Oceania or the African languages ​​with the protoindeuropean. We do not even need to leave Europe to find languages ​​without known relationship: we can draw the common origin of the Finn and Hungarian, but we cannot unite these languages ​​to the Indo -European trunk. That leaves us with two possibilities. The first is that perhaps humans began to speak time after beginning the migratory movements that would lead us to adapt to life in various territories, which would imply that several native languages ​​arose independently. That is, there are several independent trees. The second indicates that this common trunk exists, but changes in languages ​​and the absence of written testimony and time have erased all trace of this native language in the known, alive or dead languages. All languages ​​have a common trunk, but perhaps we never find out their characteristics. The question of the original language can be presented as the problem of the egg and the chicken: what happened first, the appearance of speech or geographical disintegration of the human species? The interconnection between language and expansion of humanity is not mere curiosity because answering a question can help us Date more accurately Two of the key events in human evolution. A recent study He analyzed the issue through a review of scientific literature published in the last 18 years. The work examined 15 genetic studies that through different methodologies They tried to answer the question of when the populations of H. sapiensThey began to break down and lose contact with each other. The 15 works included three based on the chromosome information and, the patrilinerally inherited chromosome; Three focused on mitochondrial DNA, inherited matrilinerally; and the rest studied the set of human chromosomes. The team made a meta -analysis, a quantitative study based on the results compiled in the compiled works, to obtain a new estimate of the last era in which in which All humanity shared spaces In the same region. The estimate indicated that this happened about 135,000 years ago. The team concludes from this data that human language had to have an origin prior to this original diaspora. They start from the idea that, if language had not existed in this origin, we should have found any human society without language or, at least, with a radically different communicative form from what we know as speaks. The details of the study were Published in an article In the magazineFrontiers in Psychology. An evolution in several phases But what exactly is speech? According to Explain the team itselfprevious studies had already pointed out that Other hominid speciesprevious to sapiens They had the ability to speak. The nuance is that this does not guarantee the existence of a language, however simple it is. The issue for the team is not when humans, H. sapiens Or other species, they began to emit sounds, but when they began to develop the language “as we know it”, that is, “combining vocabulary and grammar in a system”, a system capable of generating an indefinite amount of expressions based on their own rules. “Human language is quantitatively different because there are two things, words and syntax, which work at the same time to create this Very complex system”, explained in a press release Shigeru Miyagawa, study co -author. “No other animal has a corresponding structure in its communication system. And that gives us the ability to generate very sophisticated thoughts and communicate them with others.” Miyagawa and his team also refer to the archaeological record to support their conclusions. As they explain, the archaeological record that has left us evidence of the existence of the type of complex thought that supports the language, evidence that date back 100,000 years ago in time. The team refers to this to artifacts that denote a “symbolic activity”, such as objects in objects or the decorative use of the ocher, a pigment. We have known for a long time that H. sapiens It has not been the only human species capable of reaching these levels of abstraction. It is perhaps that is why The debate To what extent species like Neanderthals H. Neanderthalensis They could have developed speech or even language Be far from setting up. In your articleThe team indicates that, although the “complex behaviors” such as burials and body decoration They can also be associated with these species, ours would have been the only one to have systematized them throughout the population.
