The “lost continents” of our planet are leaving their trail in an unthinkable place: the earth’s magnetic field

by

Life as we know it depends largely on the stability of the Earth’s magnetic field. But this stability (or the absence of this) depends in turn on factors that we still do not understand. Some of these factors are in the outer space, others instead are thousands of kilometers hidden under our feet. From the bottom up. Huge geological structures located in the land mantle They could be contributing To destabilize the magnetic field that protects the land from radiation and particles from space. These are the “sunk continents”, the large provinces of low speed (LLVP). Sunk continents. This last name is due to the fact that these rock masses located in the deep layers of the land mantle stand out from the rest of its surroundings because the seismic waves move more slowly through them. Through this method we know the existence of two large LLVP, one located under the African tectonic plaque and the other located under the peaceful plaque. We do not know exactly what they are or what is the origin of these rock masses. A hypothesis indicates that could be remains of the impact between the primal earth and a second planet called Theia. The Moon would be one of the results of that impact, another would be that part of The remains of Theia would have been “embedded” on earth, specifically in the mantle, giving rise to these “lost continents.” However, other studies have pointed out that these masses would be formed, at least partially of ocean cortex buried through subductive geological processes, which would make them more close to “lost continents” of the surface of the earth. The new study can be linked to this last hypothesis. Fed by a “fire ring.” The team He modeled the movements Convectives of the land mantle, also creating a reconstruction of the possible movement of the tecton plates on the surface of the Earth in the last 1,000 million years. Thus they found indications that the African dough would contain older and more “mixed” than the peaceful mass, which would contain 50% more oceanic crust, a more “young” cortex and different from the surrounding mantle. This could be explained with the call “Pacific Fire Ring”, A vast network of failures, many of them subductive that little by little they engulf part of the earth’s crust. This “banquet” would have been producing for at least 300 million years and would be serving to feed the Pacific LLVP. The details of the study were published In an article In the magazine Scientific Reportsof Nature. In diversity is the key. Until now, intuition pointed out that these two underground “continents” had a similar composition. The reason is precisely that the two slow down the passage of seismic waves in a similar way, which leads us to the intuition of thinking that these are very similar in their characteristics. However, the team responsible for the new work indicates that this may not be the case. The reason is that the temperature is more than the material that makes these regions slow the waves that cross them. The balance is complicated. The formations are more or less opposite in the Terrestrial globe, which in principle is great news: since these masses influence the way in which the temperature of the earth’s core is spread in higher layers, which in turn affects the conductive movements inside the nucleus of the planet. Since these movements are those that allow the existence of a magnetic field On Earth, the way in which they occur has a lot of impact on this field. If the LLVPs are different, the way in which the field is generated ceases to be symmetrical as one would expect, which gives rise to the appearance of imbalances. Discussing the different hypotheses. As we pointed out at the beginning, the new study can be linked to the idea that the LLVPs are the result of the sinking of earth cortex pieces and not the remains of a planet of the original solar system. Although the study does not offer conclusive evidence confirming this first hypothesis, It can be seen as a new more test in this address.

Latin America and Africa are a juicy caramel for car manufacturers. And the Chinese industry is already moving file

by

The Chinese automotive industry has launched to the ambitious adventure to conquer the world. Yes last year We were talking about tariffs And both the United States and Europe looking for trying stop the expansion of the Chinese electric carnow we talk about huge ships from the main companies bringing their cars. But China Not only is your eye on Europe. It is already moving towards Africa and Latin America. Restrictions. Apart from bringing their cars to our borders, Chinese companies are moving forms for expand your dealer network in Europeas well as They operate their own factories. To ‘skip’ tariffs and restrictions, instead of manufacturing cars in the usual way, they do so by removal kits and put. But it is evident that these tariffs imposed on the electric car have been the trigger for the export to the West to cover other territories. In fact, brands such as ByD came to rethink their international strategy in some markets, and those alternative destinations outside the traditional axis are those that have lower commercial protection and greater growth potential. Africa (the north, especially) and some Latin American countries stand out for their lower customs obstacles and local policies that encourage the industry.

To the question of whether ultraprocessed foods are as bad as they have told us, science still has no clear answer

by

When going to the supermarket it is easily being surrounded by fried potato bags with different flavors, cookies, soft drinks, frozen pizzas or chicken nuggets that are part of our shopping basket. They are the so -called ultraprocessed foods (UPF), products that have gone through multiple industrial phases and often contain ingredients that are not found in house kitchen, such as corn syrup or hydrogenated oils. A debate for a long time. The alarm was given in the early 2000s Brazilian researcher Carlos Monteiro. While trying to decipher The increase in obesity and type 2 diabetes in your countrydiscovered something paradoxical: people bought less sugar and salt than before. The explanation was in the Super cart: they had replaced the basic ingredients with precooked and ready products to consume that they were loaded with these same foods. Growing evidence. From that moment on, scientists began to put the batteries to try to demonstrate whether there was a link between the high consumption of these products with health problems, because they had increased at a vertiginous pace. From there, dozens of studies associate high diets in ultraprocessed with higher risk of obesity, cardiovascular diseases, type 2 diabetes, cancer and even depression and anxiety. A large -scale study with more than 110,000 adults in the United States found that those with the highest consumption of ultraprocessing were 4% more likely to die for any cause during the monitoring period. Variations between countries. The same amount of ultraprocessing in all countries is not consumed of our area. While in the United States and the United Kingdom Almost 60% of calories come from ultraprocessed In Spain the figure is around 26-30%. Despite being in the lower part of the table compared to Anglo -Saxon countries, recent studies, such as the one published by The BMJ, alert that the strongest evidence associates ultraprocessed exposure with cardiometabolic health problems, metal disorders and mortality in general. Is El Villano processing? Despite the overwhelming correlations, not the entire scientific community agrees to demonize the ultra -processed as a category. The main argument of skeptics is that The group is too broad and heterogeneous. In this way, the question is raised if it is logical to put some donuts, fried potatoes and a supermarket yogurt in the same bag. Some researchers wonder if the association with poor health is not due, simply, that these products are usually rich in fat, sugar and salt, and poor in fiber and vitamins. However, several studies have tried to clear this unknown. A clinical trial of the University College of London He compared two dietsone based on minimally processed foods and another with ultraprocessed, but both with identical levels of key nutrients such as proteins, fats, fiber and sugar. Surprisingly, participants lost twice the weight with the minimally processed food diet. This suggests that nutritional composition is not everything. Beyond calories. A breaker essay led by physiologist Kevin Hall in the National Institutes of Health of the United States (NIH) locked -literally -20 adults In a research center and gave them freedom to eat everything they wanted. For two weeks they followed an ultraprocess diet, and two others an unprocessed diet. The results were revealing: with the ultraprocessed diet the participants consumed 500 calories more a day and won almost a kilo. Hall and others investigations suggest that energy density and food texture are key. Many ultraprocess, having less water, concentrate more calories in less grams. In addition, its texture is often softer, which leads us to eat faster. By eating faster, our brain does not have time to register satiety signals, which facilitates excess caloric consumption. Ciaran Forde, researcher at the University of Wageningen, demonstrated that people ate much less when they were presented with hard texture foods (such as gofre -type fries) compared to soft texture foods (such as potato puree), regardless of whether they were ultra -processed or not. “What we saw was that the speed of eating and the texture properties of the meals boost consumption, not the degree of processing,” says Forde. What do we do then? Although the debate on the definition and the exact mechanisms continues, the general trend is clear: a diet with a high percentage of ultraprocesses is consistently associated with worse health results. The solution, however, does not seem to be a total prohibition. Kevin Hall himself, one of the most critical researchers, admits which consumes salad salads and dressings bought in the store. His advice for friends and colleagues is pragmatic: “Eat more vegetables without starch, legumes, fruits, integral grains and limits the intake of added sugars, sodium and saturated fats. Choose the ultra -processed that help you to be convenient and affordable, and avoid those that make it difficult.” Images | Alan Alves Xataka | Making rice of more is no longer a mistake: cooling it and reheating it can reduce your calories according to some nutritionists

There will be only one young man for every three professionals who retire

by

Spain faces an unprecedented challenge with respect to generational relay of the current active population due to demographic aging. According to a recent one Study of the Observatory of the Professional Training of Caixabank Duiza and Orkestra Basque Institute of Competitiveness, in Spain there is a deficit of almost 3.5 million people under 30 years in the employed population to compensate for the weight of the population over 50 years of age than He will retire In the coming years. “There is a true demographic fire, only that it is not unforeseen, we have seen it on and extend,” declares to The avant -garde Mónica Mosa, researcher and co -author of the study. This mismatch among young people under 30 and over 50 years old It has doubled In the last decade, putting at risk the sustainability of many companies and economic activities for shortage qualified labor. Demographic differences in the working population. As the report points out, for each young person under 30 there are three workers over 50. This imbalance will make, for example, in a decade this proportion He moves To the price for retirement benefits, where a worker would support the benefits of several pensioners, increasing pressure on the pension system. In communities such as Asturias, for every 100 young people under 30 there are 257 over 65 years old, while in Castilla y León and Galicia this proportion exceeds 220 greater than 65 per 100 young people. These regions, characterized by being rural and with a High depopulation ratethey have added difficulties to attract and retain young labor in fundamental professions such as agriculture, livestock or forest agents, pillars of their local economy. The low birth rate. The main trigger for this situation is decline Birth rate in Spainwhich in the last ten years has dropped by 27%. The average number of children per woman is well below the necessary to maintain the population, which has gone from 9.11 born by a thousand inhabitants in 2013 to 6.61 births per thousand inhabitants in 2023. However, this rate varies considerably depending on the origin of the families, varying from the 8.30 births per thousand inhabitants of Spanish mothers at 16.05 of foreign mothers. Likewise, the study includes that the number of children per woman has also dropped from 1.27 in 2013 to 1.12 in 2023, being equally lower among Spanish women (1.09 children) than among foreign women (1.28 children). These last figures are a clear risk to the sustainability of the generational relief in the workplace, taking into account that at least 2.1 children per woman would be necessary to guarantee it. The impact goes by sectors. The shortage of young people especially affects sectors with traditional and technical trades such as electricity, plumbing, carpentry, manufacturing industry, construction or repair of vehicles. In this group of artisans and qualified workers record a deficit of around 500,000 young people to occupy the vacant positions left by the workers who retire in the next decade. In sectors such as public administration, difference is even more marked: For every 100 officials under 30 there are 690 over 50 years. This is one of the reasons why the Public Administration has stepped on the accelerator in the call for oppositions in which record figures have been reached. In the opposite pole, sectors linked to leisure and culture, Information and communications and hospitality are not affected by this mismatch in the generational relief since they attract a greater number of young people, contrasting with the low attraction of young professionals in industrial and administrative activities. Labor scarcity will impact the economy. The regions with the greatest presence of the most affected professional sectors such as Andalusia (Agriculture and Livestock) Catalonia and Madrid (industrial sectors), show the largest deficit figures of professionals in absolute numbers approaching (and even exceeding) close to half a million people. These communities stand out as the main focuses where the lack of generational relief will be more critical for the local and national economy since its active population percentage with respect to Spain’s total is also greater. Professional training as a key to relay. The report indicates The importance of professional training (FP) as a fundamental solution To face this deficit of new professionals in industrial sectors. According to their authors, the greatest imbalances are seen in the average grade, where there is a lower attraction of young people with respect to those of higher degree. In general terms, there is a lower generational gap among people occupied with FP. This is due to the ease of access to the labor market of young people studying professional training. However, the different branches of professional training must keep attracting young people during the next decades to balance the current deficit. On the other hand, the lack of young people trained in the care sector, whose growth is linked to demographic aging, and the talent migration of the abroad health sector complicate the balance in the generational relief. The report underlines the importance of achieving “young people stay in the territory” and connect their training with the business fabric to ensure effective relief.

More than 200,000 books for 11 euros a year. It is ‘The Free Books Club’ of Valencia, a paradise for printed paper devotees

by

In a city like Valencia, not precisely lacking second -hand librariesa project has been born that goes beyond the mere business with volumes that have already lived one or more readings. It’s about ‘The Free Books Club ‘, a mixture of bookstore, paper trace, social club and NGOs Bibliophile that, in exchange for a minimum fee, allows its partners to take all the books they want. Its responsible is Rafael Soriano, who transmits an enthusiasm for reading perfectly In line with the philosophy of the premises: “All books are jewelry, some need a little mime and that is the goal of the club: save the books, pass them from good hands to others and in that way, among all, to have an immense library of people who want to continue keeping the books.” All books They deserve be read (As Rafael says, “a book can be a brick, but if you find a page, a paragraph, a text that tells you something, is already a good book”) and therefore preserved. That is why the Free Books Club ‘has an affordable partner share, 11 euros a year, which allows you to take all the books that are desired (To donate it is not even necessary to be a partner), return them or keep them if desired. The intention of the club is that no book is discarded, and of course, that leads to problems. The main one is that Rafael stopped counting the specimens in the premises when he reached 200,000, and the lack of space has forced him to stop classifying, archiving, listing and even restore those volumes they need. In the original place there are no more volumes, which has led them to resort to “partners who have some space at home, a garage, a small warehouse. When someone requests a large rescue, let’s say ten, twelve, fourteen boxes of books, in the premises of Valencia they do not fit.” The project has thus became a completely collaborative idea: the website centralizes the calls for help in search of space, and They estimate that right now they will be around 300,000 “saved” booksas Rafael likes to say. There are future and expansion plans although at the moment the relief comes from projects as another open club in Padrón (A Coruña) with similar operation. An agreement with emails has also been reached so that the partners can exchange books directly without going through the Valencia premises, again with the website as a meeting point. Although Rafael’s ambition goes further, and would like to see premises like his in other provinces, and “that the partners can take a book in Valencia, leave it in Cáceres, take one in Cáceres and leave it in Barcelona.” Computer to Guardian de Books Rafael Soriano started his career as a computer programmer: “I started computer studies before there were computer faculties. In the year 85 I started from 88 I dedicated myself to programming for different clients. In the end the fort of my programming was the management of bars and restaurants. “Later he made the leap to the other side of the screen:” For having met the sector, I was as manager of a bar-restaurant for a year, with thirty-so many employees on the beach. “ After dedicating almost ten years he transferred him and stayed “a little in limbo: I am not yet retired, but I don’t want to be at home, even if I have some resources to endure.” And in this way the club was born: “A little like Hobby, a little as a refuge.” And near the sea, “because I like to swim, see dawn swimming.” A completely born project of devotion to the printed page and has set in something more than a bookstore: A home for old books that serves as a transit in search of new houses. Or as Rafael says, “it is an alchemy workshop, that is, everything that is there is paper, it is an piled paper, but in the right hands it becomes gold.” In Xataka | Before he died, this man left a list of everything he had read in his life: 3,599 books of all kinds that you can now consult

Our brain also “draws the garbage.” And it is one of the reasons why sleep is so important

by

We have known for a long time that sleep is more than rest, it is a vital need such as eating or breathing. Lack of sleep can have devastating consequences on our physical state, but also on our mental state. The big question for many scientists is why, a question that we have not yet answered at all, but in whose resolution we have advanced significantly. Sleep and dementia. A line of research that in recent years has gained importance has been the one that studies the role of the glinphathic system in the relationship between our dream and the appearance of dementia. The key would be in the “cleaning” work that this system exerts in our brain. The glinphathic system. The glinphathic system can be seen in certain contexts such as a cerebral analogue of the Lymphatic system. This forgotten anatomical system exercises different tasks in our body, being one of them to “take out the garbage”, clean the accumulation of waste generated by cells and eliminate harmful substances that may be present in our tissues. The lymphatic system does not extend through our brain, but someone must perform this important task in the central nervous system. A few years ago we began to understand who and how. The problem is that we have not yet managed to find out the most relevant aspects of the call GLINFATIC SYSTEM. Cleaning the plates. This cleaning work could be linked to the appearance of diseases such as Alzheimer’s. In A recent article in The conversationa group of researchers from the Macquarie University formed by Julia Chapman, Camilla Hoyos and Craig Phillips, explained this relationship. This hypothesis is based on the role they play in the appearance of the disorder Beta-amyloid proteins (Aβ). Over time these proteins tend to accumulate in our brain and, if they are not refined, they form plates that hinder the proper neurological functioning, damaging the brain and giving rise to the appearance of the disease. Night work The hypothesis that links sleep and Alzheimer’s way of the glinphathic system is also based on the idea that it is during the dream that the system takes the opportunity to clean impurities and toxins. However, the doubts about what the dream is what this relationship unleashes. As Chapman, Hoyos and Phillips stand out, studies sometimes seem to contradict, for example when measuring if the Aβ levels we find in the brain liquid are greater during sleep or during vigil. From mice to people. One of the problems we find in this line of research is that much of what we know we know it thanks to studies in micewhile the analysis with humans are limited. However, some studies have managed to approach the problem from human biology. An example cited by the team is A study Posted in 2018 in the magazine Proceedings of the National Academy of Sciences (Pnas). In it the team observed how a simple night of sleep deprivation could cause Aβ levels to increase significantly in the hippocampus. The study therefore reinforces the theory that the dream is closely linked to the probability of dementia. The risks of insomnia. The 2018 study was conducted in healthy people who experienced a night of sleep deprivation. So what about people who have insomnia or similar problems? This issue is different and requires a separate study. According to Macquarie’s team, some analysis carried out with people with insomnia and sleep apneas (interruptions caused by breathing problems) have associated these types of problems with a higher risk of dementia or with lower levels of Aβ. This again seems to support the thesis of a relationship between sleep and dementia mediated by this “cleaning system.” Another relevant issue is how sleeping pills influence, if it is at sleeping facilitate the functioning of the glinphathic system or if on the contrary the effect of these does not facilitate their night activity. A study Made in mice and published this year in the magazine Cell points to the second possibility since these compounds They did not activate the appearance of norepinephrinea compound that seems to perform an important rum in this “drain” function of toxins and other harmful compounds for the brain.

In this map we can see the countries in which cannibalism is technically legal. It falls very short

by

He cannibalism It is one of the stars of horror cinema, but also of the most cases Morbose of serial murderers. Some of the most rugged (if you haven’t seen ‘Dahmer‘, in Netflix, it is very good) They have inspired films and series. And although we might think that it is illegal to be associated with serial killers And it may seem to us A prehistoric actwe would be wrong. At least, in much of the world. The act of eating the neighbor. Eate for each other It is something that has been present for millennia. Some societies enemies ate as supremacist actsreligious or simply to obtain nutrients. In other situations, it is the despair that leads us to cannibalism. Currently, we know that it is nonsense because We don’t have too many nutrients. Now, cannibalism continues to exist. It is associated with erotic fantasies that involve eating or being eaten as part of a sex Jeffrey Dahmer either Dorángel Vargas They ate parts of their victims as an act of extreme possession and cannibal acts have also been performed as part of magical rites, such as Red Zwazulu-Natal dismantled in 2017 In South Africa. We have cannibalism stigmatized for a good reason, but a few years ago this Map by Reddit in which it was stated that there were countries in which cannibalism was legal. The image problem? Well, it falls very short. A mess. That cannibalism is technically legal in some places does not imply that it is … legal. And the keyword is “technically.” In them, and in many others, cannibalism is not explicitly prohibited by any specific law. Does not appear in the Criminal Code or in the Constitution and, For example in SpainWhen cannibalism is mentioned, it is done in the context of animal protection against cannibal practices of its species. But of course, although there is no explicit criminalization, the acts to be performed to eat human flesh do constitute a crime. The murder, the damage to the neighbor, the manipulation of human remains or the illegal exhumation are acts pursued by the law. Therefore, although we can think that there is a legal vacuum, if we want to eat the neighbor, we will have to make a crime that, usually, is persecuted. In fact, a Armin Meiwesthe ‘Canibal de Rotiburg’, He was condemned for homicidenot by cannibalism (the victim was supposedly consented, but died in the process). Legal vacuum. We entered an extremely rugged gray area here with two cases that were given in Europe not so long ago. In 2010, the Norwegian artist Alexander Selvik He ate himself. Specifically, he consumed remains of his hip extracted surgically to prepare a dish that ate as part of an artistic project. A year later, in the Netherlands, there were two television presenters who They ate fragments of their own flesh and on the other in a live program. Both cases were investigated, but since cannibalism is not a crime, as was under its will and no other crime were damaged by law, No charges were presented. What there was was a debate about ethics and the limits of art. Requests. Of course, sporadic movements have been given for politicians to study if it would be worth including cannibalism as a crime in itself. In Spain, although some voice has been manifested to legislate, no serious request has been recorded. In the United Kingdom, a citizen petition for cannibalism was included as a specific crime. After six months, the platform record 38 firms of the necessary 10,000. In the petition, they detailed the following: “Canibalism is potentially dangerous and we believe that it is a little ethical act that should constitute a crime, even if the person whose flesh and/or part of the body and/or organ is being consumed has given its consent. There should be a minimum mandatory penalty of five years in prison for committing said crime.” Asterisks. In Papua New Guinea has been mentioned as illegal Sometimes and in the Central African Republic It was missing due to social contexts such as war conflicts. It remains a gray area and that, in some cases, is an implicit activity in others that are considered punishable. For example, in Canada it is not typified as autonomous crime, but the Criminal Code sanctions “Any outrageous interference with a human body or human remains.” And then there is the case of the United States. Although a rule similar to the rest is followed in the country (there is no specific prohibition, but performing cannibalism implies acts that are crime), There is a state in which The law is mentioned cannibalism expressly, penalizing it With up to 14 years in jail. It doesn’t matter if consumed with or without consent and does not only imply direct consumption: in 2024 the law was modified so that it is also punished if another person is supplied. There is only something that would free you if you eat the neighbor in Idaho: that it is a case of extreme survival. It means that what it means (it has not been given the case, until now).

differences and how to configure your artificial intelligence to notify you

by

Let’s explain How to create reminders with artificial intelligencefocusing on those of Chatgpt and Gemini for being the most used. Both applications have two completely different systems to create these reminders, so we are also going to tell you the differences. You are already one of those people who use a specific application for reminders or of which a message with Telegram or a similar app is programmed to remind you something, this is a very interesting alternative. With this, you will give the artificial intelligence a new use, so that The day you want at the time you ask you send you a notification To remind you something. Two different ways of sending reminders Chatgpt and Gemini bet on two completely different methods To send you reminders. This is the reflection of the philosophy of each of the companies, one betting on its AI as an autonomous service and another integrating it into its service ecosystem. On the one hand Chatgpt sends you reminders autonomously. When you configure one, will send a notification in all devices where you have the application installed. Will also send you an email In case you did not have the apps installed or you have not given them permits to send you notifications. Besides, Gemini creates the reminders in the Google Task app. This means that you will have to link Gemini with your other Google services, and you will also need to have the Tasks application installed on your mobile. That on the mobile, because on the computer it will work through the browser and tasks. As you see, ChatGPT simplifies reminderswhile with Gemini they complicate a little when depending on another application that is also from Google. But if you are already a person accustomed to using Google apps, this will make everything be integrated into the ecosystem you already use. In addition, the fact that Gemini takes the reminders to a specific application for them will also facilitate the way to manage them. In chatgpt you will have to look for them in the chat Where you have configured them, but in the case of Gemini you can go directly to Tasks, something that will save you time. Come on, there are positive and negative points in both methods. Anyway, in both cases you can Create reminders by writing them or by voicesince both AI have hands -free functions to speak by voice or the possibility of sending audio messages. This will greatly facilitate things at those moments when you can’t stop writing the Prompt. Create Reminders with Chatgpt To create a chatgpt reminder, you have to write a prompt in which you ask that Create a reminder in a day and an hour concrete, then putting what you want me to put in the reminder after two points. For example, you can use this prompt: “Create a reminder for tomorrow at 4:30 p.m. saying: Visit Xataka Basics.” The structure and composition of the prompt can vary, You can write it in your way with natural text as long as you mention the key data of the date, time and content. Chatgpt will be able to understand what you have asked. At the time you make the request, A window will appear showing the reminder. In this window you can see the content, date and time, and you can ask you to do any correction simply by telling you what you want me to change. And that’s it. When the specific time comes, Chatgpt will issue a notification with the reminder. He will do it as a notification of the app, although he will also remind you in the chat where you did the request. In addition, you will also send you an email so that there is no way to forget. Create reminders with Gemini To create a reminder in Gemini, you have to write a prompt in which you ask you Create a reminder in a day and an hour concrete, then putting what you want me to put in the reminder after two points. For example, you can use this prompt: “Create a reminder for tomorrow at 4:30 p.m. saying: Visit Xataka Basics.” The structure and composition of the prompt can vary, You can write it in your way with natural text as long as you mention the key data of the date, time and content. Gemini will be able to understand what you have asked. Gemini will need you to activate your access to Google Workspaceand so I can use Google tools of your account. If you have not done it, you will see a picture where you have to click on Continue To go to a screen where you must activate the Intelligent functions in Google Workspace. When you have linked workspaces, at the time you ask you to believe the reminder, A window will appear showing the reminder on Google Tasks. In this window you can see the content, date and time, and you can ask you to do any correction or go directly to Google Tasks to do it. In the event that you do not have it, You will have to install the Google Tasks application On mobile, available In Google Play For Android and In the App Store For iOS. You will have to log in with the same Google account you use in Gemini. And that’s it. Now, when they arrive the day and time where you have configured the reminder, Google Tasks will issue notification To remind you what you have asked.

The Los Angeles Plan to turn waves into megawatts

by

They look like piano keys dancing on the Pacific, but they are blue floats that rise and go down to the rhythm of the waves in the port of Los Angeles. At first glance, they could go unnoticed, but in reality they hide a promise: transform the inexhaustible force of the sea into clean electricity for thousands of homes. Short. The company Eco Wave Power He successfully completed The operational evidence of its first pilot project in the United States just a few days ago. The key moment was the descent to the float water, Transmitted live by Good Morning Americaa symbolic gesture that marked the beginning of the operational phase within the Energy Mix of California. The company has an ambitious plan: it wants to cover with floats the 13 kilometers of the breakwater that protect the port of Los Angeles. This installation could generate electricity for about 60,000 homes, According to Eco Wave Power press release. More in depth. The system uses eight floats fixed to a concrete dock. At first glance they seem piano keys, but their function is much more complex: with each movement of the waves, the floats act on hydraulic pistons that push a biodegradable fluid through pipes to a unit of energy conversion (ECU) installed on the ground. Inside, it works almost like a small hydroelectric plant. The accumulated pressure moves a turbine and, with it, electricity is generated. The entire system fits in two 20 -foot maritime containers, which makes it easy to transport, mount and maintain. The key is in the location. Other projects were launched inside and ended up sunk by the cost of submarine cables and the damage of the storms. Here, however, the floats are anchored in existing port infrastructure. And if you arrive bad weather, they get up as if they were retractable awnings to avoid damage. “When the waves are too high, the floats simply go up until the storm passes, so there is no damage,” The CEO Inna Braverman explained to Techxplore. But not everything is perfect waves. Undimotriz energy has been promising for decades and fulfilling little. The teams in the open sea suffered constant damage, and the repairs were very expensive. The coastal model of Eco Wave Power seems to solve part of the problem, but it is still an experimental technology. We need to check if you can compete in costs with giants such as solar or wind, today cheaper than ever. “The Achilles heel of this energy is in the maintenance and inspection costs. Therefore, to have a device near the coast, from where you can walk and review it, it makes a lot in statements collected by Techxplore. However, we must not forget the current American political context. While the federal government REduce support for green technologiesstates like California continue advancing on their own towards carbon neutrality in 2045. In that pulse, the echo pilot Wave Power works almost as a statement of intentions: although Washington goes in another direction, innovation continues to find holes to emerge. A symphony of the sea for the future. The official inauguration is scheduled for September 9 in Altema, in the port of Los Angeles, and a new chapter in the state’s energy transition is expected to mark. For now, the floats continue to move like aquatic piano keys. But if they fulfill their promise, they could compose a different melody: that of a future in which the ocean sway illuminates an entire city.

When the Nazis occupied an island on the Channel of La Manchas they met an unexpected enemy: an indecipherable language

by

The enemies sometimes appear for the most unsuspected places. That is what the German soldiers who occupied the Canal Islandson the Canal de la Mancha. The campaign promised them happy and in fact it extended for several years, but shortly after putting the first foot on the island of Jersey the Nazi officers realized that they would have to deal with an unexpected enemy: a language that they did not understand their interpreters. And that was a luck for the locals. In a place on the Channel of La Mancha … It is found Jerseythe largest of the islands of the Canal, an archipelago located very close to the French coast but is administratively linked to London. In fact they are considered British crown dependenciesautonomous, self -governor territories and that strictly are not part of the United Kingdom, but they are linked to their crown. It is estimated that in 2001 a few resided in the archipelago 150,000 people distributed in Two dancers: Guersey’s and Jersey, where they live more than 100,000. An island, its own language. Jersey not only stands out for his geography, status and history. It also does it at the linguistic level: on the island you speak English, French … and The sweater (Jèrriais), a tongue related to The Normand and, They claim The island authorities, have a rich history of more than a thousand years. His first written record dates in fact the 12th century, with The poet Waceand on the island presume of its literary legacy of the late eighteenth century. The sweater He caught his attention Even from the prestigious French writer Víctor Hugo, who rescued one of his words, Pieuvre (octopus) in your novel ‘The sea workers’of 1866. “A Language of Peasants”. The history of the Jersejés is not exactly simple. Despite his age and the enormous roots he has had on the island, there was a time in which he considered a vulgar and stigmatized language, which has irremediably marked his base of speakers. “In 40 and 50 if you went to school the Jerseyés was prohibited. It was considered a language of peasants, spoken only by poor people. That was the attitude of all teachers, even those who spoke Jerseyes,” He recounts To the BBC François Le Maistre, a almost 90 -year -old man who explains that in his home, as a child, only the island language was used. … And a weapon in front of the Nazis. Interestingly and despite his stigmatization, the sweater played a relevant role during World War II. The Canal Islands hold the sad honor of being the only “British” islands that endured the occupation of German troops during World War II. The Nazis came to Jersey between June and July 1940 (with The battle of England as a backdrop) and remained in the archipelago until May 1945. The authorities evacuated 30,000 people From the Canal Islands before the arrival of the Germans, but even so when Führer’s troops landed in Jersey they met thousands of locals (the archipelago added in total 104,000 residents) With a disturbing peculiarity, especially for the Nazis: they spoke a seemingly unintelligible language, even for the Francophone Germans. Not even the collaborative interpreters understood at all. What devils are they saying? “The articles in Jerseyes published at the beginning of the occupation managed to transmit messages of resistance”, Point out to the BBC Geraint Jennings chain, linguist and expert in the island language. “The texts openly said that it was better to speak Jerseés so that ‘certain people’ could not understand it, that is, the Germans! Of course they soon realized and took drastic measures with censorship, but the sweater continued to be used as a secret language to transmit messages during the rest of the contest.” In the island’s passive resistance strategy, that language related to Normando became a valuable piece. Its complexity, even for the ears of the German soldiers who spoke French or the collaborative performers, made the Jerseés a key tool to exchange information, draw clandestine plans or even, remember The English chain, mock of the Nazis. “Everyone spoke”. “During those years everyone spoke Jerseyes simply because, unfortunately of the Germans, it was not possible for them to understand our language,” remember I maistre. Perhaps it sounds strange, but it is that within the jersey itself different dialect varieties of the language were used: despite the fact that the island is small, a good part of the islanders were related to their own communities, which favored surprising wealth of expressions, words and even accents, distinctive marks of groups of speakers. On other channel islands, such as Guerneey, Sark and Alderney They also had their own languages, some already disappeared. A dream for linguists, a nightmare for German soldiers who walked through Jersey. A tongue in retreat. That does not mean that the sweater was immune to war. His starting point was already delicate. Although in the 30s the mother tongue of most people born on the island remained, it was minorized and stigmatized. To that was added “the great social rupture” that, Jennings lamentscaused the German occupation: families evacuated to England with their children ended up adopting English as the main language, the same that happened to the islanders who enrolled in the Armed Forces and then returned home. This rupture is added that tourism and the island’s financial sector, key pieces in its economy, They contributed to boost English as a communication vehicle. And what is the situation now? Complicated. There are reasons for optimism, but also for concern. In recent years the language has managed to claim, with institutions expressly dedicated to its promotion and greater sensitivity on the part of local institutions. In February 2019 in fact the island authorities They declared it COOFICIAL LANGUAGE IN THE ASSEMBLY WITH ENGLISH AND FRENCH. Who today lands at the island’s airfield is also with a message that welcomes him in the language: “Seyiz Les Beinv’nus à Jerri”. That is the positive part. The refusal … Read more
