Neuroscience is debunking the myth of “crazing” the night before

by

Given the need to want to study a specific topic efficiently, we can do numerous searches for the best technique to achieve itespecially those of us who are students. At first, science and education have maintained an almost unbreakable dogma: for a brain to associate two events and learn, constant repetition is the key. but now nuances have been added. What we do. Nowadays, it can be a study technique to stay up all night with coffee in hand trying to cram an entire syllabus intensely in a short period of time. This way, we only see the syllabus once and never again. But this is not the best study, reading or productivity technique in general. An evolution. For decades, classical learning models, such as those based on traditional reinforcement learning, assumed that the more times you are exposed to a stimulus followed by a reward (or hit), the faster you learn. However, a revolutionary study from the University of California, San Francisco (UCSF), led by researcher and published recently in Nature Neuroscience has shown that we were looking at the problem backwards. And we saw it the other way around because the important thing in study is not how many times we expose ourselves to new knowledge, but the time that has passed between two temporal moments in which we have begun to study a concept. And this is precisely what tools such as the famous flashcards that appear in the educational field with increasing force take advantage of. What has been seen? The research team in this case carried out experiments with mice where dopamine was measured that freed your brain, pointing to the fact that the learning rate scales proportionally with the time interval between rewards, and not with the number of trials. To understand it easily, if a mouse has a long interval between two stimuli, it needs much fewer repetitions for its brain to release the dopamine necessary to consolidate what it has learned. This is why we see how the brain optimizes learning based on the total time invested in a spaced manner, making quick and repetitive bursts of study very ineffective. Because? We already know that spacing out study is best for our memory, but… Why does this happen? Here science tells us that dopamine acts as a very specific teaching signal in our brain circuits. In this way, when learning something new, dopamine updates our “predictions” retrospectively. When we try to understand why our memory works this way, we see that too much dopamine during intensive initial learning can even impair early memory consolidation, causing us to be so overwhelmed that we retain nothing. But when it has time to act, it has the ability to strengthen the synapses to establish knowledge in our long-term memory. Simply put, if we don’t let the brain rest between repetitions, the neurochemical consolidation processes are not allowed to do their job. In real life. As we have been repeating, this is the scientific basis that establishes the bases of the study focused on flashcards or even in well-known applications such as Duolingo to learn languages. These systems take advantage of spaced repetition to maximize the retention in memory of the new knowledge they are faced with. And in case evidence is missing, a study done on medical students has shown that using double-spaced repetition techniques compared to single-spaced or traditional intensive study increases long-term knowledge retention drastically, since 62% retention is achieved, while before the study 52% was retained.

A 4.6 billion-year-old “recorder” was hidden in asteroid dust: what it said changes what we knew

by

We think of memory as something linked to memories that fade or transform over time. But there is another form of memory that is much more precise and stubborn, one that does not depend on people or technology and still preserves information with extraordinary fidelity. Some rocks are capable of recording the magnetic environment in which they were formed. That is what happens with the dust of a very particular asteroid: small particles that have preserved a magnetic signal for billions of years that today allows us to reconstruct what the solar system was like in its early stages. That “record” is not a metaphor. It comes from particles collected on the asteroid Ryugu and brought to Earth in 2020 by Japan’s Hayabusa2 mission. As Eurekalert points outa team led by Masahiko Sato has analyzed their magnetic behavior and has found signals that suggest that these particles retained information from the environment in which they were formed. This opens the door to reconstructing what the magnetic fields present in the protoplanetary diskthat is, the “nursery” where the planets were formed. {“videoId”:”x86bfqj”,”autoplay”:false,”title”:”JAMES WEBB: A TIME MACHINE and a SPACE TELESCOPE”, “tag”:””, “duration”:”504″} A trace that cannot be erased. The key is how some minerals react to the magnetic field when they form. Its internal structures, formed by small magnetic domains, are oriented following that field and remain “locked” when the material solidifies. That process leaves a lasting mark that scientists can measure today with highly sensitive instruments. This phenomenon, known as natural remanent magnetization, turns these particles into physical witnesses of the past. The challenge. The first analyzes of these samples offered very different conclusions: some studies suggested that they preserved a stable magnetic signal from the early solar system, while others argued that they had formed in a region with practically no magnetic field. There were also those who suggested that the signals detected could be due to contamination during analysis on Earth. Part of the problem was based on these works, which were based on a very limited number of particles, just seven, which made it difficult to obtain solid conclusions. New samples. To resolve these discrepancies, The team significantly expanded the number of particles analyzedgoing from seven to 28, which allowed us to work with a much more solid statistical base. After applying demagnetization techniques to eliminate possible modern signals, the results showed a clearer pattern: 23 of the 28 particles retained a stable magnetic signal. Of these particles, eight showed two stable components and one presented spatially inhomogeneous magnetization directions, something difficult to explain if the signal had been introduced later on Earth. In Xataka We have a serious problem in our plans to colonize Mars: the astronauts’ blood is mutating Why is it important. The detected signals suggest that these materials originated in an early phase of the solar system, approximately between 3 and 7 million years after its formation. They also point to water alteration processes in the asteroid’s parent body. So we can say with great confidence that Ryugu is not just a pile of rocks: it is a valuable archive of the early solar system that has allowed us to better understand the magnetic environment of those times.

The bill is 45,000 euros and two lost trials

by

When a traffic light stops working there are road rules that we must follow until it is repaired. The worst thing is when this repair takes several days, causing chaos in traffic. That was what happened in 2023 in Valencia, and the dispute between the Superior Court of Justice of the Valencian Community (TSJCV) and the maintenance company remained unresolved until a few days ago. What happened. For five days in November 2023, the pedestrian traffic light located on Doctor Manuel Candela Avenue with Santos Justo y Pastor Street showed the red light and the green light at the same time. According to they count From El Motor, the first alert was registered on November 14 at 6:45 in the morning. Four days later, a municipal inspection confirmed that the problem remained unresolved. Why did it take so long? The origin of the failure, according to the Valencia City Council, was that the company that had to take charge replaced the burned out halogen lamps. for other LED types with E27 socket. Municipal services described them as “glaringly unsuitable for traffic light networks.” The problem, furthermore, was not only the type of bulb that was used, but the technical procedure they followed to install them. A procedure that municipal reports described as “technically inappropriate.” blegal attack. The City Council imposed a penalty of 45,000 euros on Electronic Trafic SA, the company awarded the contract. The company appealed, arguing that it had resolved two different breakdowns, both in less than two hours, and that the council had “deliberately” confused the terms breakdown and incident, which would entail different economic implications depending on the contract. He also alleged “animosity” from the head of the Mobility Service towards the company. The courts did not see it that way. What the judges said. The TSJCV confirmed the sanction on February 26, supporting the City Council’s thesis. The sentence highlights “the seriousness of the behavior followed by the contractor”, which left the incident unresolved for more than four days at an intersection where there is special traffic. The court highlighted that the municipal reports were “highly precise and exhaustive” and that the company did not provide sufficient technical evidence to refute them. According to point The Motor, in addition to the 45,000 euros, the company must pay 2,500 euros in procedural costs. What this sentence implies. The issue here is that the company notified of the problem but the traffic light continued not to work correctly during those days. Therefore, the city council insist in which the responsibility falls on the company, from notification to solution. The failure being a traffic light, a critical road safety device, all the more so the urgency of finding a solution. More and more cities are outsourcing intelligent traffic management to private companies, and the ruling certainly sets a precedent. What happens now? The crossing operates normally. The ruling still allows for an appeal, although the fact that two different courts have endorsed the city council’s position means that the company has little room for maneuver.

Spending a night at one of LVMH’s most exclusive vacation spots isn’t cheap: $70,000 a night

by

There are luxury resorts. And then there are places for which there is still no category that does justice to what they offer. He Cheval Blanc Randheli Private Island, located in the Maldives, cobra $70,000 for a single night stay in its facilities. And no, we didn’t miss any extra zeros when writing it. The property belongs to the LVMH hotel divisionthe same group behind luxury brands like Louis Vuitton, Moët & Chandon or Tiffany & Co, and what it offers for that price goes far beyond a bed overlooking the Indian Ocean: an island just for you. A resort that was already unattainable for most Cheval Blanc Randheli is located on Noonu Atoll and can only be reached by seaplane from Malé, capital of the Maldives. He LVMH luxury hotel It is divided into two islands: one where the main resort is located and a second island, separate from the main one, whose price can reach $70,000 per night. That is to say, for that price you are not renting accommodation in a villa, nor a presidential suite. It is literally a private island, with its own beaches, its pier, its dedicated staff and more than 8,000 square meters of total area. A proposal for which the word “exclusive” falls short. The luxury resort opened its doors in November 2013 as part of the Maisons collection of the brand. The main complexlocated on the largest island, is the one that welcomes the most guests, with 45 loft-style villas distributed between overwater, garden and beachfront options. Each of them is equipped with private pool infinite edge. The experience offered by this resort begins even before arriving, as guests They travel on the private seaplane by Cheval Blanc after a stay in an exclusive waiting room in Malé. Common facilities include five select restaurants, a Guerlain spagym, water activities and even the only surf simulator with artificial waves in the Maldives. Conventional villa rates at the main resort are now out of reach of most pockets. According to the accommodation portals in the areatheir prices range between $2,268 and $7,688 per night depending on the type of accommodation. The island of millionaires Cheval Blanc Randheli Private Island is an independent island separated by just 50 meters of deep turquoise sea from the main island. It has a surface area of ​​one hectare and is only accessible through a private pier. The island houses an exclusive mansion four bedrooms with approximately 2,200 square meters built, with capacity for up to eight guests. The master bedroom has panoramic views of the ocean, double bathroom, dressing room, office and its own living room. The residence also includes two family rooms on the ground floor and a separate villa for companions who prefer more privacy, making it an ideal option for families or groups of friends. This paradisiacal mansion also has three connected living rooms, a piano lounge, a private bar and a 25-meter-long pool complete the set, creating the feeling of living in a luxury tropical residence in the middle of the Indian Ocean. Beyond the luxury accommodations and equipment for the exclusive inhabitants of this island, it also includes a private spa with treatmentsgym, movie theater, tropical gardens, private beaches, pergola for outdoor dining and meditation pavilions. So that you do not lack anything during your stay, the service It is run by a resident team dedicated exclusively to the island’s guests, available 24 hours a day. A private boat connects the island with the rest of the resort, so that guests can change islands whenever they wish and eat in the restaurants, bars, kids club and diving center of the main complex, without sacrificing an ounce of their privacy. All for the modest price of 70,000 a night. In Xataka | Hotel chains no longer just offer luxury rooms: Ritz-Carlton dives into the superyacht business Image | Cheval Blanc Randheli

Renfe is already maneuvering to get a new contract in France. And the 1,000 million euros at stake is the least of it

by

Arrive in Paris. Three words to summarize Renfe’s great objective in the neighboring country. After living with competition on our roads for more than five years, the Spanish company seeks to achieve one of its great challenges in its international expansion. A new route originating or ending in Paris is underway. But, so far, France has not made it easy. Target: Paris. Be that as it may. And Renfe is already preparing an offer to participate in the tender for the Paris-Dijon-Lyon line. That is what media outlets like Expansion either Forbeswho state that the Spanish company will participate in the tender to operate a route that, ten years from now, would be valued at around 1,000 million euros. The striking thing is that this line is not high speed. The link between Paris and Lyon that Renfe will serve uses regional trains, contrary to what the Spanish company has always pursued in the neighboring country. It would be, for the moment, his only way to reach Paris, a city that continues to resist him. A complicated landing. And Renfe has tried to reach Paris by all the means at its disposal. These were, as could be expected, offering their services on a high-speed line as required by Europe and Spain is allowing Ouigo and Iryowith French and Italian origins respectively. However, France has tried to torpedo As far as possible, Renfe runs its lines. Right now, the Spanish have managed to launch a corridor between Madrid and Marseille and Barcelona and Lyon. However, the French have managed to protect the arrival of the Spanish company in Paris, where a very substantial part of the high-speed business is located. What has been argued from France is that Renfe trains do not meet the technical criteria to be able to operate on the lines that reach Paris. And in this way he has achieved that Renfe will not operate in the city while the Olympic Games were organized from Paris, which would have given a great boost to his project. Go for the regionals. Aware of the difficulties they are encountering to continue expanding their borders with high speed, Renfe has decided to take the leap with regional trains. In Forbes They explain that the process requires the final offer for the Paris-Dijon-Lyon line to be presented before the end of 2026. Next year the award of the line would be confirmed and between 2029 and 2030 the company that has received the approval must begin operating. Renfe’s great rival, everything indicates, will be the French SNCF. The Burgundy-Franche-Comté region, which is responsible for this line, has already put out a first batch of the tender that fell into the hands of the local company with hardly any opposition, they point out in Five Days. And in Spain? As we can see, Renfe has already shown interest in operating on regional trains in neighboring countries. However, in this case it is Spain that is putting all possible obstacles to delay competition on this type of lines in our country. According to the deadlines established since In 2016 the Fourth Railway Package will be approvedcompetition on these lines should have been a reality from December 25, 2023. In 2024, the contracts should have been awarded. However, Renfe is still the only company that currently offers this service and it does not seem that it will change. And it is that The Government has been working to delay the launch of new competitions in these ways. According to ABCthe current Renfe contract extended from 2018 to 2027. This year, 3% of the contract was to be put out to tender but the Government and Renfe have signed, without making it public, an addendum to it that extends said contract until 2028.

Sleeping in tourist class has been an impossible mission. Some airlines are testing three seats that convert into beds

by

Traveling in economy class on a long-haul flight usually means accepting a fairly clear toll: sleeping poorly or, at all, not sleeping at all. We have all experienced it, narrow seats, little space to stretch our legs and a posture that rarely invites rest. That discomfort is not a minor detail, it is part of the experience of flying in this segment. And yet, it is precisely there, in this very everyday problem, where some airlines are beginning to explore solutions within the economy cabin itself. If we go to the opposite extreme, we have seen the reference to what it would be like to fly in absolute comfort many times in airline campaigns. The Emirates ad with Jennifer Aniston illustrates this wellgoing from a cabin without notable services to a private suite with a completely flat bed, that is, to the premium end of the experience. The proposal is not limited to improving comfort, it completely redefines life on board. An attempt to make tourist class habitable And at that point is where we begin to see concrete movements. United just announced a proposal of this type with its call Relax Rowan option within its own economic class that seeks precisely to alleviate that problem. The company presents it as a specific row that, once in flight, can be adapted to stretch out or rest with a little more space. The airline plans to launch it in 2027, place it between United Economy and United Premium Plus and progressively deploy it on more than 200 Boeing 787s and Boeing 777 from now to 2030. But the truth is that this idea is not completely new. Air New Zealand has been exploring this concept for some time with his well-known Skycoucha proposal that also starts with a row of seats in economy class. In its case, the system allows the legrests to be raised until they form a continuous surface on which we can stretch. It is not equivalent to a premium cabin bed, but it does offer more versatile space than the conventional seat and the airline itself presents it as a way to gain comfort without paying for a superior cabin. If we go down to detail, the interesting thing is not so much the configuration itself, but what it allows once we are in flight. Both proposals seek to expand the available surface so that we can really stretch out, something that is not usually common for tourists. Air New Zealand specifies that area in about 1.55 meters long and 74 centimeters wideaccompanied by additional bedding, a seat cover and specific belts or restraint systems to use it safely. United, for its part, adds an adapted mattress, blankets, extra pillows and kits designed to make rest more bearable. With all this, the logical question is who is really compensated by this type of option. United’s promotional video gives us an idea. If we travel alone, having all that space gives us a much more usable surface to stretch out. In the case of couples, the idea is to share it in a more flexible way, alternating positions or using it to rest better during the flight. And if we think about families, especially with small children, Air New Zealand considers different configurations. Now, before imagining a perfect rest, it is worth taking into account some conditions. In the case of Air New Zealand, as we have seen, availability depends on the aircraftroute and operational or regulatory factors, and not all configurations are always accessible. In addition, the price is not fixed, since each passenger’s ticket is paid plus an additional cost for this option, while United has not yet detailed prices, although it has indicated that its deployment will be progressive. Taken together, these proposals don’t completely change what it means to fly economy class, but they do introduce an interesting nuance. The idea is not to replicate a first-class suite, but to offer a little more room to rest within the usual limitations. That balance between cost and convenience is what seems to be guiding these developments.

in China they explore an alternative inspired by nature

by

For years we have associated drones with a very specific image: unmanned devices with several propellers rotating at full speed, capable of recording, monitoring or even form figures in the sky at mass events. It is the reference that we have internalized and the one that usually comes to mind when we think about these devices. However, it is not the only possible way to understand a drone. While this model has been consolidated, proposals have emerged that seek to replicate the flight of living beings instead of depending on rotors, opening a path that until recently seemed closer to fiction than to real engineering. Drones with wings. According to 163.coma team from Beijing University of Science and Technology has developed several flapping-wing drones inspired by animals such as eagles, pigeons, butterflies and beetles. Among them, the model based on an eagle has attracted special attention for one specific fact: it has reached 256 minutes of continuous flight, a figure that marks a record within this category. The chain itself also recalled that in 2023 a bionic airplane developed by researchers at the Northwest Polytechnic University of China recorded 185 minutes and 30 seconds, then a Guinness record in this area. Another way to fly. If these prototypes are attracting attention, it is not only because of their appearance, but because of the technical principle on which they are based. Global Times defines them as bionic unmanned aerial vehicles capable of imitating the flight of living beings by flapping their wings. According to the same medium, it is the type of drone that most closely approximates the flight of flying organisms in nature. Added to this base, in the model inspired by an eagle, is a visual system designed to recognize, locate and follow vehicles, people, buildings or license plates, as explained by researcher Wu Xiaoyang. What we do know. It is advisable to separate what is confirmed from what has been interpreted from these images. Information disseminated by Chinese state media describes these drones as an advance in research into bionic unmanned systems, with progress in flight time and detection capabilities. However, it does not offer details about its operational deployment or specific use in real scenarios. In fact, researchers point out that challenges related to flight autonomy and system intelligence still need to be resolved before talking about broader implementation. There are obstacles. If we look beyond the current results, the experts themselves point out that the road ahead remains demanding. According to Wang Zhijie, from the Beijing Institute of Technology, one of the main challenges is developing batteries with greater energy density that allow this type of flight to be sustained for longer. Added to this are high-precision, small-sized beating mechanisms, as well as materials capable of adaptive deformation, imitating how bird wings change in response to aerodynamics to maintain efficiency. In that context, what we have is a technology that points in several directions, but is still being defined. Global Times possible uses in environmental monitoring, rescue and other specialized missions, although without specifying how or when they will materialize. Beyond that, research remains focused on making these systems more autonomous and efficient. If this evolution is confirmed, we would be facing a different path in the development of drones, one that seeks to get closer to biological flight instead of continuing to perfect the more conventional scheme.

Magnesium has become the trendy sleep supplement. This is what science really says

by

It is undeniable that magnesium has reached a great fame among many people who see the need to take it absolutely every day as just another medication that their doctor has prescribed. And it is no wonder, since the great list of benefits that have been sold in recent months about magnesium invites anyone to take it because it supposedly improves everything. Although some of these benefits are really dubious, such as limprovement in sleep quality. The evidence. Right now science try to find the relationship that can justify that magnesium has an important role in our quality of sleep. In this case, observational studies suggest that good levels of this mineral are equivalent to better sleep, but clinical trials suggest that the benefits are barely noticeable. Especially when we talk about patients who have started magnesium supplementation. There are examples. A key systematic review of 2023 put the cards on the table after analyzing different studies, pointing out that people who themselves maintain a good level of magnesium snore less, suffer less daytime sleepiness and have a better sleep duration. The problem comes when controlled trials of supplementing magnesium to people who have sleep problems do not show a consistently good result. But they go further, seeing that the benefits depend mainly on two factors: Take high doses of magnesium with a daily intake of 500 mg. Previous status of the patient, since it works better if the patient previously had a magnesium deficiency proven by a blood test. Where is it most noticeable? Here a 2012 study with elderly people suffering from primary insomnia who took 500 mg of magnesium for eight weeks demonstrated a tangible change, as it not only improved sleep hours, but also increased efficiency. The physiological changes shown were an increase in melatonin, a reduction in serum cortisol, which is the stress hormone, and a reduction in latency, as it was confirmed that magnesium reduces the time it takes for an older person to fall asleep. There are many formulas. The interest in magnesium has led different companies to begin creating different presentations that improve its absorption. In this way, recent trials between 2024 and 2026 have evaluated doses of 1 gram daily (for periods of 3 to 6 weeks) in young and middle-aged adults. To measure the effect, here the researchers used rings like the Oura Ring to achieve a significant increase in deep sleep phases, and also a notable improvement in general efficiency. The small print. Given all this, we can conclude that, if you do not have a magnesium deficiency in your blood, supplementing it does not make any sense to improve sleep quality. This reminds us how important it is to follow medical advice and request an analysis to determine possible treatment and look for the reasons for poor quality sleep. This way, if you have a sleep deficit, you don’t have to go out and buy magnesium at the supermarket because someone has said on TikTok that its effect on our quality of sleep is almost miraculous.

Shakira wants to put 300,000 people in a place that does not convince the Government at all

by

Live Nation and Shakira have now officially presented Macondo Park, a 40-hectare temporary venue at the Iberdrola Music in Villaverde designed for close the tour ‘Women no longer cry’ with a nine-concert residency in Madrid in September. The problem: the Government delegate in Madrid has been warning for years that the space does not meet security conditions for massive events and has formally asked the City Council not to authorize them. Stadiums make money. What Shakira and Live Nation have presented is not exactly a concert: it is a temporary infrastructure designed ad hoc by the international study BIGknown for projects such as the Danish pavilion at the Shanghai Expo or the expansion of the National Museum of Qatar. According to data from the organization, the so-called Shakira Stadium will occupy four hectares within the Iberdrola Music space, with capacity for 50,000 people per night: 26,688 seats in the stands, 25,000 standing and around 3,000 in the VIP area. Macondism. Macondo Park will be deployed around the stadium, which takes its name from the fictional town created by Gabriel García Márquez in ‘One Hundred Years of Solitude’: 40 hectares active for twelve hours each concert day. The cultural program, baptized ‘Es latina’, includes gastronomy, workshops, exhibitions and sales of Latin American crafts, all selected by Shakira herself. There will also be a specific area for children called Macondito, designed (according to the organization) with the participation of the artist’s children, Milan and Sasha. The goal, according to Live Nation, is to “demonstrate what it means to be Latino” and project that cultural imaginary in Europe. Minitour without moving. Some pertinent figures: nine performances in Madrid, scheduled for September 18, 19, 20, 25, 26 and 27, to which have been added October 2, 3 and 4 due to the very high demand and how quickly the pre-sale sold out. The entire project expects more than 300,000 attendees throughout the residency. Ticket prices range between 73.50 and 181.50 euros, with VIP packages exceeding 1,000. And it will take 69 days to build the complete structure of this spectacular theme park around the artist. Problems in Villaverde. This great plan collides with a somewhat complicated background. Iberdrola Music is the same space that has hosted the Mad Cool festival for years. It was also the scene of the Harry Styles concert in 2023, where organizational failures led to monumental traffic jams and part of the audience ended up walking along the M-45. In the letter he wrote to the City CouncilGovernment delegate Francisco Martín recalls that he already warned about the venue in July 2023 on the occasion of the Reggaeton Beach Festival. According to Martín, in an institutional meeting held in 2024 it was found that there continued to be “relevant deficiencies in terms of accessibility, mobility and organization of entry and exit flows, incompatible with the celebration of large events in safe conditions.” The administrator of the Mad Cool festival even faced a request for a two-year prison sentence from the Prosecutor’s Office for violations related to noise pollution. It’s not a festival. Martín also differentiates between the festival model, where the public enters and leaves in stages for hours, and the “fan phenomenon”: a massive concert where 50,000 people try to leave the venue in a very narrow time frame. It is this second scenario that, in his opinion, Iberdrola Music is not prepared to absorb. Crossing of accusations. As it could not be otherwise, this open letter was followed by an exchange of accusations with little or nothing to do with music. Borja Carabante, Urban Planning delegate of the City Council, accused Martin of “trying to boycott, harm and harm the city.” Mayor José Luis Almeida pointed in the same direction: he described it as “extraordinary” that Shakira chose Madrid as the culmination of her tour and even hinted that up to ten dates could be held. Mariano de Paco, Minister of Culture of the Community of Madrid, defined it as “great news.” The preceding Adele. Promoter Pino Sagliocco, president of Live Nation, avoided entering the political fray. He defended that the mobility plan “is already done” and endorsed by engineers, and insisted that Iberdrola Music is “an experienced and well-conditioned space.” He compared Shakira’s plan to Adele’s precedentwho established his residence in a park in Munich, comparable in size to this Macondo. The center of the debate. There is slaps for pre-sale ticketsbut municipal authorization has not been granted, and the Government Delegation has made it clear that it will go “as far as necessary” to ensure that the venue offers guarantees. For now, there is silence from both sides of the Administration. The conclusion of all this is that the debate is not led by Shakira, but by Madrid’s real capacity to manage massive events outside the urban center, with access infrastructure that several reports consider insufficient. After 17 countries, Shakira’s tour culminates in the only place on the planet where organizing a live show means invoking a perfect storm.

The generational conflict with Generation Z is costing us a lot of money: $56 billion

by

There is a silent war in offices around the world over the focus on AI adoption at work. It has no declared sides or visible battles, but its devastating effects already have a price: a scandalously high one. We are not talking about employees who lose their jobs because an AI does its jobwe talk about an intergenerational war that has been declared between the baby boom generation and generation Z due to the discrepancy of use of this technology. The damage it is causing that confrontation It is not nonsense: almost one working day lost per week for each employee, in addition to projects that do not progress and burnt-out workers who, instead of looking for solutions, are looking for a new job. A very very expensive war. A published study by Salesloft and the consulting firm Workplace Intelligence based on surveys of 2,000 employees, puts figures on the intergenerational battle for the implementation of AI and other technologies that is being experienced in some US companies: 56,000 million dollars a year in terms of lost productivity due to conflict between generations. These losses are not due to misuse or ignorance of technology or lack of employee performance, but because boomers and Gen Z have communication problems and have different expectations about balance between work and personal life. A day’s work wasted for not understanding each other. That conflict between employees more veterans and those who have just joined, translates into a combined loss of 5.3 hours per week of lost productivity for each employee. Steve Cox, CEO of Salesloft, explained the phenomenon in his report: “The $56 billion productivity loss is just the visible cost. When AI adoption is fragmented, the damage multiplies and leads to missed forecasts, slower execution, and higher turnover quarter after quarter. At that point, generational conflict is not a culture problem; it is a balance problem.” They prefer to talk to a bot. A relevant fact from the study indicates that 39% of Generation Z respondents say they prefer to be directed by an AI than by a boomer, while 25% of boomers prefer to work with an AI than with a fellow Gen Z. That’s how heated the mood is. The tensions do not remain only in the environment, this intergenerational friction is causing 28% of Generation Z workers to acknowledge that they are looking for another job so they don’t have to work with boomers. Similarly, 19% of boomers say they are considering early retirementpartly because he can’t stand his younger colleagues anymore. AI, gasoline or solution? Although many of them have indicated that they prefer to have a bot as a boss rather than someone from the “rival” generation, artificial intelligence is aggravating the situation instead of softening it. The problem is that 64% of employees admit that they are not even using the AI ​​tools they already have available well. The study reveals that 60% of boomers surveyed believe the way Gen Z uses technology is hurting customer relationships. Young people, on the other hand, respond in the same tone: 64% think that boomers’ resistance to adopting new tools is slowing down innovation, and 63% say that this attitude is costing them many sales. However, there is room for optimism because both generations agree in some aspects. 86% of respondents believe that AI could improve knowledge sharing between generations, 80% that it could reduce the experience gap, and 79% of participants believe that it could improve communication between teams of different ages. The clash is not just about AI: it is about values. Beyond the tools and the adoption of technology, the underlying problem is values ​​at work. 71% of Gen Z respondents believe boomers value plus the hours in the chair than the results obtained, and 56% point them out as those responsible for the toxic environment that exists in many companies. On the other hand, 64% of more veteran employees believe that Gen Z puts your personal life ahead of the job needs. The assessment of these employees is correct and confirms it a study on job preferences among generation Z prepared by the consulting firm Robert Walters. 52% of the young people interviewed stated that avoided promotions to not take on more responsibilities that were not going to translate into economic benefits or a great evolution in their work career, but rather into more stress and loss of work. time for your personal life.
