Experts agree that “the quality of rest depends on whether you go to bed at the time when your body is ready to sleep”

by

When you read the question “what time should you go to bed?” He usually waits for a number, a specific time, a recurring pattern to do as the day ends. Bad news. What research has discovered is that the ‘perfect time’ for going to bed is with parents. That is, genetics (chronotype) and a handful of other things. That’s why it’s time to see what the experts say. The time to go to sleep. These days, there are some statements from dr. Celia García Maloneurologist specializing in Sleep Medicine and co-director of the Madrid Clinic CISNe in which she explains that the quality of rest does not depend only on the number of hours. On the contrary, it often depends on sleeping at a time when the body is biologically ready for it. This is interesting because it shows a paradigm shift in global sleep science. That moment matters, yes (but not that much). In 2021, Nikbakhtian and his team reviewed sleep routines of more than 100,000 adults. The interesting thing about this study is that they did not use self-reported responses, but rather what a week of wrist accelerometer data said. Their conclusions were clear: going to bed between 10:00 p.m. and 11:00 p.m. was associated with a lower cardiovascular incidence. It was bad news for Spain, the European country that takes the longest to go to bed. However, the details are important: it was not a question of ‘the earlier you go to bed the better’ (because going to bed before 10pm was also a problem); It was about finding the appropriate moment for each society, country or culture. And that’s where the surprises begin. Because what we are discovering is that regularity is the key. In this case, the Windred team reviewed data from six years of life of about 60,000 people. Their conclusions were that the most regular quartiles showed between 20% and 48% less mortality from all causes compared to the most irregular ones. This is because, we now believe, genetic variants are associated more with schedule than with duration and quality of the dream. The researchers’ thesis is that when we find a stable time to go to bed, the rest of the pieces begin to organize themselves. What does all this mean? For us mortals who just want to sleep, there are a handful of consequences: There is no magic hour. What we have to do is look for a stable window: if we find a time to go to bed, the rest of the system tends to adapt. However, chronotypes exist. It’s a good idea to find out which one is ours and “negotiate with it.” Take care of your dream. Although we sometimes insist on sleeping at a certain time, we often forget that sleep hygiene (and, above all, light) is one of the most important things to sleep well.

Pediatricians agree on new food fads for children: “It can cause nutritional deficiencies”

by

There are many diets that we find on social networks in recent years that advocate be really restrictive with certain foods and nutrients that demonize. The problem is that these restrictive diets designed for adults with the aim of making them look healthier are causing nutritional deficiencies in children, as pediatricians themselves already point out. The alert. The Spanish Association of Primary Care Pediatrics (AEPap) has been clear in its latest report pointing out that ‘nutritional fads’ have made a strong impact on children’s nutrition and can cause “nutritional deficiencies.” And the culprit is the adoption of restrictive diets such as prolonged fasting or the exclusion of gluten without receiving advice from specialists. But these diets are not limited to adults who want to lose weight or improve their health, but are generally applied to all members of the household. And this is explained by Dr. Marta Castell, pediatrician at the Campanar Health Center in Valencia, who point to the following: More and more families come to consultation with a proactive interest in the healthiest eating pattern, but also with great confusion between scientific evidence and fads such as 2-exclusion diets or ‘superfoods’ without clinical evidence. The enormous amount of information they receive becomes massive and often contradictory. The problem of extrapolating it. Restricting food groups without clinical justification has a very high physiological cost during the growth stages that the little ones in the house are experiencing. This is why pediatricians warn that the withdrawal of essential nutrients without a prior diagnosis of intolerance such as lactose or celiac disease is dangerous. And this practice can interrupt the caloric intake and essential micronutrients for the child’s body and especially for correct physical and brain development. The recommendations. Here the medical institutions they point because one should avoid diagnosing alleged eating pathologies at home, and apply a restriction without the advice of a specialist doctor. But in addition, one should avoid applying nutritional advice aimed at adults to minors that is disseminated by content creators without scientific endorsement on social networks. One of the clearest pieces of advice that the Vithas Medimar Hospital points to in its web is that “the best prevention against obesity and malnutrition is to recover a diet rich in vegetables, fruits, legumes, fish, nuts and seeds, and free of ultra-processed foods.” Veganism. The scientific debate does not criminalize dietary choices such as veganism, but requires absolute rigor in its pediatric approach. Something important to highlight is that a child can be perfectly healthy following a diet without animal consumption, but this “does not consist only of raw fruits and vegetables,” explains pediatrician and neonatologist Miriam Martínez Biarge, who describes poorly planned diets as “reckless.” From the clinical point of view, the Spanish Society of Out-of-hospital Pediatrics and Primary Care warns that in the vegan population there is a high risk of vitamin B12 deficiency. This deficit can have “serious neurological consequences,” being a particularly critical risk in infants breastfed by mothers who do not take supplementation. For this reason, clinical guidelines recommend the possible supplementation of vitamin B12 in the event that foods fortified with it are not consumed.

They have asked 1,600 experts how the Universe works. They don’t agree on almost anything

by

We continually read news about new findings that they defy the known physics of the Universe. This may lead us to ask ourselves something: do we know so little about the Universe that absolutely everything challenges it? To answer this question it is important to give a little context. Yes, a lot is known about astrophysics, but when we talk about something as immense as the Universe, even that “a lot” can fall short. Furthermore, much of this information is based on hypotheses that have been accepted as consensus, but not on absolute truths. Therefore, it is not strange that in the largest survey ever conducted It has been proven to astrophysicists and astrophysics fans that there is a lot of disagreement on almost everything related to the cosmos. The largest survey. In 2024, during an astrophysics conference in Copenhagen, a survey was carried out in which 85 experts participated. All of them had to answer a series of questions about some of the best-known theories in astrophysics. With this survey it was seen that there is a lot of disagreement, even in those theories in which there is supposed to be a great consensus. In order to check whether these disagreements were a result of the sample size, a new survey was carried out in 2025, this time with 1,600 people who had to answer 11 questions. Some participants were experts from the American Astrophysical Society. Others were amateur readers of Physics Magazine. With a larger sample, the results were very similar. There is very little consensus. From hypotheses to certainties. Science in general, and astrophysics in particular, is built on hypotheses that evolve as scientific advances are made. For this reason, it is often more full of probabilities than certainties. It is important to differentiate different branches of science. In health sciences, there are certainties. For example, we know that antibiotics attack bacteria and are not useful against viruses, no matter how many people insist on taking them for the flu. We also know that their abuse can be very harmful, since it contributes to the development of resistance in bacteria. Those are certainties, although logically there is also information that evolves over time. In astrophysics, hypotheses accepted by consensus often outnumber certainties. There are very clear certainties, such as that the Earth is not flat or that it revolves around the Sun. But also some hypotheses with which not even experts agree. Cosmic inflation wins. The issue on which there was the greatest consensus in the 2025 survey, the results of which were recently published, was cosmic inflation. That is, the hypothesis that points to an exponential expansion of the Universe which began in its first moments, after the Big Bang. 51% of respondents agreed that this theory explains many problems in cosmology at once and therefore has a high probability of being true. Talking about the Big Bang. The existence of the Big Bang was another of the theories with the greatest consensus in the survey, although the truth is that the figure is nothing to write home about either. 25% of the participants agreed that this event gave rise to the Universe 13.8 billion years ago. On the other hand, there were 68% of people who indicated that the Universe was born at a time when there was a large increase in temperature and density, but they did not indicate when that occurred. Disagreements with dark matter. Gravitational behaviors that do not respond to the observed mass have been observed in the Universe. That is, it seems as if there are massive objects exerting a gravitational attraction on others, but these objects are not detected, not even large accumulations of atoms. There is nothing. 27% of those surveyed consider that this can be explained by the existence of dark matter. However, there are 12% who believe that all this may be due to changes in the behavior of gravity on cosmic scales. That is to say, when we talk about the immensity of the Universe, the gravity exerted by objects is not the same. On the other hand, there are 5% of people who consider that the key is in primordial black holes. Although here we must emphasize that one of the hypotheses about the origin of dark matter is that it is formed in part by primordial black holes, so they would not be denying its existence. String theory to solve incompatibilities. The theory of general relativity was proposed on large, cosmic scales. On the other hand, quantum mechanics talks about the behavior of matter on a subatomic scale. Both questions seem incompatible, but to understand the Universe we need to work at both scales. Therefore, for a long time there has been thought about a theory that helps unify both issues. This, for 19% of those surveyed, is string theory. In it, subatomic particles, instead of being treated as points, are considered vibrational states of a more basic extended object, called a string. Normally, when we try to calculate the energy of a particle by considering it a mathematical point, without extension, we get closer to it eternally. We can do a kind of infinite zoom. On the other hand, when the points are replaced by strings with a minimum length, a result must necessarily be obtained. It does not tend to infinity. On the other hand, in string theory gravity, which not normally considered on a quantum scalearises naturally. Another hypothesis. The point is that, in the survey we are talking about, there are 12% of people who consider that string theory does not solve the problem, but that another theory does: that of loop quantum gravity. This, basically, acts in a completely opposite way. String theory emerges with quantum mechanics as a starting point and tries to find ways to make gravity make sense. On the other hand, the theory of loop quantum gravity starts from the General Theory of Relativity and attempts to quantize it in a way that … Read more

All experts agree that introducing bison into Spain is a bad idea. And yet we’re doing it

by

Nine European bison have been grazing for four months in the Guadalajara municipality of El Recuenco, in the heart of the Alto Tajo. And the only really relevant question is why. I mean, we know why. They are there because the Rewilding Spain foundation and the town council itself have placed them in what has become the first case of bison in public forests in Spain. In fact, as long as we pay attention to what its promoters say, it is not only a renaturalization initiative, it is “a tool against forest fires.” The thing is, none of that explains why anyone thinks any of this makes sense. There have never (as far as we know) been European bison in Spain. Yes, yes. I know that one of the most iconic Spanish images is that of the painted bison of Altamira, but that animal was not a Bison bonasuswas a Bison priscus. A species that became extinct 9,000 years ago just when the habitat (the mammoth steppe) that welcomed it did. There is no conclusive paleontological evidence to say that there was ever a European bison on the peninsula. In fact, in 2020, MITECO commissioned a report that unanimously denied that this animal could be defined as an “extinct species in Spain”. Does that mean that it is proven that there was not? No, one thing does not imply the other. At any time we can find remote proof that there were. In fact, in February 2026 was announced that a skeleton about 4,000 years old had been found in Navarra that could be from a Bison bonasus. It is a matter of time before a genetic test confirms it (or not). Be that as it may, no one seems to care: the nine bison are in Guadalajara. And there are up to two doctoral theses that will examine fecal samples, stress levels and diet to study the adaptability of these animals and their effect on vegetation. The latter is interesting because, as I said, the second objective of all this has to do with vegetation. With its control and management. There it is, despite the skepticism of many expertswhere there may be a future. But it is not a simple future. To begin with, because the species cannot be the subject of an official reintroduction program. The nine specimens from El Recuenco (and the other 160 in the country) are not protected wildlife, but are classified as livestock or zoological nucleus. This requires them to be controlled, geolocated and monitored. But, above all, that forces us to ask ourselves many things and “do we have any capacity to control our country?” It is perhaps the most important. For years, people have been releasing beavers into the main Spanish rivers without anything happening. What’s more, in Spain have been detected more than 200 invasive species. The debate is not ‘bison yes or bison no’. Above all, because it is not a strictly Spanish debate. The United Kingdom reintroduced bison to Kent, the Netherlands did it decades ago… European rewilding is being done, to a large extent, outside the usual channels of conservation. And El Recuenco is just the local version of a deeper debate: that of what nature we want to exist in the future.

He James Webb Space Telescope It has been targeting the most remote regions of the universe for years and, with each new observation, it has revealed something that doesn’t quite fit. In his images, small, tiny, bright red dots appear, which repeat with a frequency that is difficult to ignore. They are not a specific anomaly or an observation failure: they are objects that astronomers have been studying for some time without having yet achieved a convincing explanation of their nature. The novelty. A recently published study in The Astrophysical Journal, led by Devesh Nandal and Avi Loeb, from the Harvard-Smithsonian Center for Astrophysics, opens an alternative to the most widespread interpretation. Specifically, it suggests that some of these red dots might not be systems dominated by active black holes, but rather supermassive stars formed in the early universe. Speaking to Live ScienceNandal argues that this type of star can explain key features of these objects without depending on the presence of growing black holes. Before this turn, the so-called “little red dots” had already been on astronomy’s radar for some time. The term began to be consolidated in studies published in 2024, when several teams began to analyze them systematically after the first Webb observations. We are not talking about a recent discovery, but rather an accumulated enigma: At Xataka we already address it as a phenomenon that is difficult to fit into current modelswith very compact, extremely luminous objects present in the early universe. The dominant hypothesis. During the first years of analysis, the explanation that gained the most traction was that these red dots were driven by growing black holes. In the first phase, some of the researchers attributed its red color to dust in the environment, although later work has shifted part of that focus to hydrogen gas. What is starting to not fit. With the passage of time, some observations have complicated this initial interpretation. Several of these objects do not show clear X-ray emissions, one of the most common signs of active black holes, and their spectra lack strong metallic lines beyond hydrogen and helium. Added to this is “The Cliff”, one of the objects analyzed by the RUBIES program, which does not fit either as a conventional galaxy or as a system dominated by dust. The proposal of the new study fits into this context, which proposes a different reading for at least part of these objects. Instead of active black holes, some small red dots could be supermassive stars formed from primordial gas, composed almost exclusively of hydrogen and helium, and observed just before collapsing. According to the model developed by the team, this scenario reproduces both its extreme brightness and specific features of its spectra, without having to assume the presence of a growing black hole. The new study does not close the debate, rather it expands it. The researchers themselves acknowledge that directly demonstrating what lies behind these objects remains extremely difficult, and other voices in the scientific community insist that none of the hypotheses can yet be ruled out. The presence of black holes in these systems remains to be demonstrated directly and, for now, is inferred mainly from their brightness and how abundant they are.

The “shitification” of the internet is everywhere and seems inexorable and inevitable. Norway does not agree

by

When we say that any time in the past was better, perhaps we are erring on the side of idealizing the past, but when it comes to the Internet the phrase becomes more relevant. We have normalized online experiences to degrade with fewer features, more ads, new subscriptions… The only thing missing was the AI ​​garbage to finish finishing it off. It seems like nothing can stop the shittification of the internet. Nothing less Norway. A day in the life of a “shitter”. This is how it is titled the video that the Norwegian Consumer Council has published to report a situation. It shows a man who makes holes in his socks, saws the leg of the table so that it is limp, dries some markers with a hairdryer… He defines himself as a shitter: “What I do is take things that are perfectly fine and make them worse,” he says. The video is very funny and is part of a campaign against a not so funny problem: the degradation of digital services. The organization has developed a complete report in which they describe the problem and propose a plan to address it. Shitification. It is a term coined by writer Cory Doctorow and declared word of the year by Macquarie Dictionary in 2024. The definition is as follows: The progressive deterioration of a service or product caused by a decrease in the quality of the service provided, especially in the case of an online platform, and as a consequence of the search for profits We are not talking about natural degradation, but something deliberate that responds to an economic objective. A clear case has been that of Netflix, which not only chased shared accountsbut eliminated functions such as the possibility of casting from the mobile phone to the television. Not to mention the ads on payment planssomething that has spread to practically all streaming services. Theard everywhere at once. But this phenomenon reaches all types of services, not just streaming. We see it in the form of more ads on apps like Instagram (many of them of scamsby the way), It happened to me with the security camera app I had at home and there are even those who bought a connected refrigerator for thousands of euros so that they could start ads appear on the screen. Of course, companies offer you a solution to remove annoying ads: ✨pay a subscription✨. The phases of shitification. It is not something that happens overnight, but first they attract you with an attractive service, that works well and offers advantages. Once they have a solid user base – when they have caught us – the party begins. A good example was Uber, which in its beginnings offered very low prices to present itself as a more attractive alternative to taxis and now it’s more expensive. Generative AI makes it worse. According to the Norwegian report, far from solving the problem, AI is making it even worse. He junk content made with AI It is the most visible face, but they cite many more examples, such as Google AI Summarieswhich are often inaccurate and weaken the information ecosystem. There are also the AI-based advertising algorithms that make more ads reach us, platforms that are forcefully integrating AI everywhere, sometimes taking advantage of it to raise prices. Norway’s proposal. The use of this type of practices is widespread and its advance seems unstoppable, but Norway proposes three lines of action to reverse it: Give power back to users: that we can decide which operating system to install on our devices, that interoperability is mandatory, protect “de-shit” tools such as ad blockers and alternative recommendation algorithms. Stop depending on big technology: force them to “open the doors” and use open standards, finance and promote free software, using public administration as a lever. Apply the law: Norway proposes raising sanctions even further and tightening controls. The European Digital Markets Act has already taken steps in this direction, such as USB-C on iPhone or the sideloading on iOS. However, managing to end this degradation completely seems like a titanic task. Norway has sent letters to fourteen countries, including the United States, asking them to take action.

We have been hearing for years that plastic is safer than wood. Jordi Cruz does not agree (and it seems he is right)

by

Science has spent decades studying what happens with E.colithe Salmonella and company when they touch the wooden, plastic or metal boards that we use in the kitchen. It is an old (and we thought unsolvable) fight, but the famous chef Jordi Cruz has spoken. He said it on TikTokbut since the ways of distributing content on the Internet are capricious, he has also said so in tens of websites. The question is whether what he said makes sense. What does Jordi Cruz defend? In essence, Cruz has commented your prints on three cutting board materials (plastic, metal and wood). Furthermore, it has gotten wet: for him, the best option is wood. As explainedwhile plastic is filled with grooves where bacteria accumulate and metal destroys the edge of the knife, wood has “natural antibacterial and antimicrobial” properties, where bacteria “get between the fibers and end up dying.” The controversy has been enormous, of course. A curious debate. That “clear” comes from the fact that for years it has been said that wood is the material that “accumulates the most bacteria”, in contrast to “non-porous” plastics that can be put in the dishwasher (and can be cleaned more easily). It is logical that seeing a famous chef say that wood is the best has made many put your hands on your head. However, Cruz is not as off track as we might think. What the evidence says. From the very beginning (the pioneering studies by Dean Cliver at the University of Wisconsin in the 90s), research they have been giving us back the same image: There is no evidence that plastic is inherently safer than wood. Appropriate (hard and closed-pore) and well-preserved wood creates a hostile environment for many bacteria. The problem is that. Wooden boards are not only more expensive, but require maintenance. And if we are not going to give it to them, plastic with all its problems is safer. Although not totally sure, of course. That is to say: the most dangerous boards are the old, scratched and poorly washed ones. The material does not matter, what is important is its state of conservation. And then? Some time ago, food safety experts stopped focusing on the material and began to look for strategies that would try to reduce the main risk derived from the tables: cross contamination. A good example of this are the recommendations of the North American USDA. For the Agency, both wood and other “non-porous” surfaces are acceptable for things like meat and chicken. Their main recommendation is another: use a table for raw meats and a different one for ready-to-eat foods (in addition to always cleaning them with hot water and soap; and subjecting them to periodic disinfection). In Europe the recommendation is similar and, in fact, he adds that although there may be more or less appropriate materials depending on the use, “in domestic kitchens the priority is hygiene and not the specific material.” What do the chefs say? What Jordi Cruz says (that a wooden board is best as a “main board”) is a general consensus between chefs and gastronomic influencers. However, it is common to restrict them to chopping cooked vegetables, fruit, bread and produce. On the other hand, also it is common to use plastic with meat and raw fish. Or what is the same, for “dirty uses.” Sometimes we get stuck in absurd debates. And this is a good example: the public debate has dedicated a lot of effort to establishing the idea of ​​”bad wood/good plastic”, when the important thing is to use several boards, assign them fixed uses and clean (and replace them) when necessary.

8 kilometers of ice have been lost in two months and researchers only agree on one thing: it is something to worry about

by

Predict their future the antarctic glaciers It is undoubtedly a great challenge for science, but the most important thing above all is to know How will it affect global sea level?. The worst of all is that the latest news we have at our disposal is not at all positive, since the Hektoria glacier It has retreated 8 km in just two months, which is an unprecedented speed in the modern era. Where we start from. Normally, the retreat of glaciers It is measured in hundreds of meters per year. It is one of the clearest metrics we have to be able to ‘measure’ global warming, and that is why now what a team from the University of Colorado Boulder has just recorded on the Hektoria glacier, on the eastern peninsula of Antarctica, plays in a completely different league. The measurement. In just two months during 2023, the Hektoria lost almost half of its mass. In total, 8 kilometers of ice disappeared. A speed of collapse that has never been seen in modern history and that, according to the authors of the study, is more typical of the end of the last ice age. Something that doesn’t add up in this case. Hektoria is relatively small by Antarctic standards (about 300 km², less than the city of Malaga), but its collapse was so sudden that it left researchers stunned. A coincidence. Ironically, the research team wasn’t even studying Hektoria. They were analyzing satellite and remote sensing data for another project when Ochwat realized that the glacier had essentially disappeared from the images. The measurements. This is where technology comes into play. The team had to combine data from multiple satellites to understand what had happened and, above all, how quickly he did it. “If we only had one image every three months, we couldn’t say that the glacier lost two and a half kilometers in two days,” explains Ochwat. In this case, by combining images from different satellites you can fill in the time gaps and confirm with evidence in hand how quickly the ice has been melting. But the key was not only in the images. They also used seismic instruments that have the ability to detect a series of “glacial earthquakes” that occurred exactly during the period of rapid melting. And these earthquakes are not measured for the sake of it, but to confirm something crucial: the glacier was anchored to the bedrock (and not floating) just before breaking. This is fundamental both for science and for the entire planet, since ice that is floating (such as an ice shelf) does not raise sea level when it melts, any more than an ice cube does in a glass of water. But ice that rests on land (or anchored to a seabed) and falls into the sea does contribute to the global rise in sea level by increasing its volume. Your Achilles heel. The collapse was not due to simple superficial melting. The cause was topographic, since many Antarctic glaciers rest on deep canyons or underwater mountains. The Hektoria, however, had the misfortune of resting on an “ice plain”: an area of ​​bedrock that was exceptionally flat and below sea level. This flat topography caused a gigantic section of the glacier to begin floating all at once, rather than gradually. The moment the glacier lost its anchorage to the ground (its “line of support”), it was exposed to the forces of the ocean, and therefore everything began to advance very quickly. The process was brutal, since it all began with the warmest ocean water that seeped underneath and began to open cracks from the bottom of the glacier upwards. At the same time, the glacier already had cracks on the surface. Eventually, the lower and upper cracks met and the glacier literally disintegrated. A warning for future glaciers. The Hektoria case is a first-rate warning. Scientists know that there are numerous glaciers in Antarctica that also rest on these types of ice plains. Until now, it was thought that their collapses would be centuries-long processes. Hektoria shows that they can be months, which should set us off due to the implications it would have on sea level. And while the collapse of a small glacier like Hektoria won’t dramatically change global sea level, it alone does demonstrate that a rapid collapse mechanism, until now theoretical or believed to be typical of past geological eras, is perfectly possible today. If this same mechanism is activated in much larger glaciers, sea level rise could accelerate very considerably and much sooner than expected.

The question now is whether the deceased would agree

by

The possibility of “resuscitating” the dead is something that We have already seenbut with artificial intelligence tools the thing goes beyond a simple Deepfake. Imagine being able to maintain a conversation with a loved one who died every time you want. Well, with its virtual version. It sounds like Black Mirror episode, but the trend is growing. This opens new doors for duel and memory, but also raises legal and ethical questions about control and consent about digital identity after death. Duel technology. The ‘Grief Tech‘Use technology to help people cope with the loss of a loved one. As? Creating digital versions with which they can interact. It is one booming trend. In China, the Deepfakes of loved ones They are increasingly popular. The emergence of increasingly advanced artificial intelligence tools allows the result to be more realistic. There are companies doing business with this, such as HEREAFTER AI either Sence ai That based on tattered conversations and memories, they create a chatbot with which to hold a conversation. Others take it further and create an interactive video-Avatar. This is the case of Re; Memory, You, Virtual Only either Storyfile. The latter has helped the Lista family, protagonists of this NYT reportto create an avatar of his father who suffers from terminal cancer. These virtual ghosts have also been used for other purposes, such as This created from a murdered young man to cause a greater impact on the jury. Why this happens. Save memories of our loved ones when they die is something that humans have done For millennia. Objects, photographs, videos or an avatar with AI, all respond to the need to remember the link we had with that person. However, it is not the same to look at a photo than to maintain conversations with a digital replica of a dead loved one and raises doubts of its consequences, both at the psychologic and ethical level. The duel in the AI ​​era. This type of digital chatbots or avatars can be comforting at specific times, questions about their effect on long -term mental health arise. The loss of a loved one is a very painful process and, if complicated, can lead to weakening symptoms. In statements a EuronewsDr. Kirsten Smith, a clinical researcher at the University of Oxford, said: “There is evidence of multiple studies that indicates that the search for proximity (behaviors destined to restore closeness to the deceased person) is related to worse results in mental health.” Some of these ‘Grief Tech’ services as it is already in mind and are presented as a temporary tool to help process the loss. In their case they offer a payment model for each session with the chatbot and also its use time is limited. What does the law say. Who decides who can be resurrected with an AI? The truth is that there is no legislation that prevents creating one of these ‘posthumous avatars’. The works created by a person are protected by the Intellectual Property Lawbut not your voice, photos or videos. He General Data Protection Regulation in force in the European Union does not apply directly to deceased persons and, in the case of the call Digital willit focuses on user profiles on social networks and accounts of different services That do not resurrect me with ia. In Ars Technica They talked about this subject and raised the question: can you put in the will that they do not “resurrect” with ia? We do not know if someone has done it, but it may not serve much without clear legislation. If someone creates a ‘digital ghost’ of a deceased without permission, family members could request that it be eliminated, the problem is that it is the relatives themselves who request it (which would be the most logical).

This incident occurred only three months after the driver was hired as a temporary worker with the aim of covering a new route. After being discharged in the German hospital, the truck driver found himself in a difficult situation that justice has described as “negligent actions” and “uncontending.” Despite having a work decline due to the surgical intervention they had undergone, the company demanded that it lead more than 674 kilometers to Strasbourg, where a partner who was on a route back to Spain picked him up and returned together. However, this return trip, far from being direct, included multiple stops and additional distribution tasks assigned to the partner he had collected. Finally, the return was an odyssey that lasted until eleven days later of the medical incident. Welcome home: You are fired The truck driver’s adventure did not end with his return to Spain. Upon arriving at Elche on December 23, He notified him the dismissed Without prior notice. The company did not officially communicate the dismissal until a week later, under the pretext of needing its presence to “sign documentation.” This dismissal was considered by the truck driver as zero for violation of fundamental rightsspecifically the right to physical and moral integrity. In addition, it was argued that dismissal occurred as a result of the worker’s state of health, which could be considered Disability discrimination. The company, meanwhile, tried to justify its actions. They argued that dismissal was not such, but a “valid extinction of a temporary employment contract due to the circumstances of production.” According to the company, temporary hiring responded to specific market needs, such as covering a new route to Norway and Sweden during the winter and Christmas campaign, and that service had concluded. The company insisted that, for the return, the instructions of the mutual for the worker’s medical assistance had been followed and denied any discrimination or violation of fundamental rights. However, these justifications were not enough to convince the court. The court ruling The Superior Court of Justice of Valencia issued a Judgment in favor of the truck driver. The High Court supported that the company had acted contrary to the protection of the worker’s physical integrity by forcing him to drive in precarious health conditions after having suffered a heart intervention. The sentence declared the nullity of dismissal forcing the company to readmit itand ordered compensation of 30,000 euros for the truck driver for moral damage derived from the management of his return home. The court rejected the company’s allegations on the legality of the TEMPORARY CONTRACT EXTINCTIONconsidering that the cause of temporality had not been properly justified. This judicial decision sends a clear message to companies about the need to prioritize the welfare and safety of their employees collected by article 19 of the Workers Statuteabove the operational demands.
