There are people capable of testing positive in a breathalyzer test without having drunk a drop of alcohol. And we already know why

by

Although it may seem crazy, failing a breathalyzer test after drinking only water and a plate of pasta is possible. And while explaining it that way to a police officer may raise questions about a poor excuse, The truth is that it is a medical reality for those who suffer from the known self-fermentation syndrome. The investigation. Until now we attributed this problem to yeast, but a team of researchers from UC San Diego and Massachusetts General Hospital has identified specific strains of Escherichia coli and Klebsiella pneumoniae as those responsible for generate intoxicating levels of ethanol in the intestineopening the door to treatments as surprising as fecal transplantation. That is, there are bacteria that can literally make us drunk without drinking a drop of alcohol. The metabolic storm. To reach this conclusion, the study analyzed to 22 patients diagnosed with this metabolic problem, comparing them with 21 healthy relatives. In this case, the results were quite compelling, because fecal samples from patients in the midst of the outbreak were capable of endogenously producing ethanol at alarming levels. In order to know much more, These samples were cultured and an ethanol concentration of up to 136 mg/dl was observed.. To put it in context, in many countries the legal limit for driving around 50 mg/dl in bloodso these patients without drinking would be doubling the level of alcohol permitted while driving. An alcohol factory. The novelty of this study is that it shifts the focus from yeast to bacteria, since genomic analyzes showed a massive enrichment of genes related to mixed acid fermentation. But we must not fall for the statement that these bacteria are ‘bad’, but rather that the ecosystem is broken to give rise to this problem. And what is the trigger? The antibiotics. And the use of these drugs can sweep away the balanced flora, allowing opportunistic pathogens to take control of the intestine and begin to metabolize sugars into alcohol. The treatment. Logically, this is a serious problem, not because of the fact of testing positive in the alcohol test, but because of the toxicity that the body faces. That is why the objective right now is on the treatment that now has the focus on a fecal microbiota transplant. For this study, the donor of his fecal microbiota was a personal trainer with enviable intestinal health. And the result was incredible, since the patient with this problem saw these problems disappear permanently, and his ability to “self-produce” alcohol disappeared after repopulating his intestine with the healthy bacteria of another person. Beyond getting drunk. As we have said before, it may seem ideal to have a feeling of intoxication without having to spend a single euro on a drink, but the reality is that this problem also leads to non-alcoholic fatty liver disease. And constantly producing alcohol can cause very serious liver damage. But on the social issue, this endogenous overproduction of ethanol has led people to lose their driving license or face labor problems unfairly. All for a problem that may seem like the perfect excuse, but is actually a major medical problem.

that short people cannot be police officers

For much of the 20th century, height requirements in Spanish police forces were inherited from models designed for parades, controlling public order on horseback, and an intimidating physical image as a symbol of authority. Those scales were set at a time when police work was much less technical and professionalized than today, and they were barely revised for decades. Requirements of the past. Yes, they were times when the police forces in Spain and in much of Europe dragged access criteria born in a context very different from the current one, when authority was associated with presence and police models drew directly from military structures of the 20th century. The minimum height was then consolidated as an automatic filter that was barely revised over time, even when the police function evolved towards increasingly technical, legal and citizen-friendly tasks. Starting in the 1990s and, above all, in the last two decades, this requirement began to be questioned in courts, parliaments and administrative reforms due to its discriminatory nature and its poor relationship with the actual performance of police work, which led to its progressive elimination in many European countries and, more recently, in Spanish state bodies. Andalusia now reaches that turning point after many years of delay. End of a legacy filter. Thus, as of February 22, Andalusia will leave behind one of the most discussed requirements for access to the Local Police: the minimum height. The new decree that regulates entry, promotion, mobility and training eliminates a physical bar that for decades excluded fully qualified applicants, aligning the Andalusian local police with European practice and with other State bodies that had already abandoned that criterion. The decision is based on a clear premise: prioritizing talent, preparation and vocation over a fixed body condition that says little about the actual performance of police work. Real equality. The standard is not limited to deleting a requirement, but rather introduces conciliation measures for applicants in a maternity situation, avoiding disadvantages during the selection process and reinforcing the principle of equal opportunities. The message it’s explicit: access must evaluate capabilities and merits, not penalize personal circumstances or perpetuate barriers that are not directly related to the police function. The reinforced model. The decree redefines initial training and places it under the leadership of the Institute of Emergencies and Public Security of Andalusia, together with accredited municipal schools and the possibility of approving courses from other entities. The entry course is strictly linked to the training phase, with a minimum charge of 650 hourswhile staff internships are separated and developed under municipal supervision. In addition, the way is opened for trainee personnel to carry regulatory weapons, once again equating them to other state bodies. Unified calls. Plus: one of the keys to change is the possibility of unified callsthrough an agreement with the city councils, to centralize and streamline selective processes. The grading system “is reorganized into modules that require balanced excellence, age groups are eliminated in physical tests and an agility circuit is incorporated, already present in other models.” The syllabi are updated and the psychotechnics are divided into two phases, one during the opposition and another in the admission course, with professional endorsement. That the short ones can too. On the whole, the reform corrects a grievance that had gone on for too long: preventing access by a question of height when the profession requires judgment, preparation, endurance and commitment to public service. With this decree, Andalusia not only modernizes its Local Police, but also sends a symbolic and practical signal to thousands of applicants: the uniform will no longer depend on how tall you are, but on what you know and how you are prepared to serve.

Thousands of workers were needed to build the colossal Golden Gate. Just to maintain it you need 200 people

by

There are few symbols as recognizable of the United States as the golden gatethat colossal orange bridge inaugurated in 1937 that crosses the San Francisco Bay. And no wonder: 1,280 meters of bridge hanging on two 227-meter-high towers with 600 thousand rivets each. It enters through the eyes and also, it also sounds. The subject of countless photographs and an extra in numerous films and series, it is also the place chosen by many people. to end his life. The colossal construction of the Golden Gate. When the Golden Gate opened almost a century ago, it was considered an architectural landmark that combined engineering and modernity. And no wonder: the work lasted more than four years, cost more than 35 million dollars (from the 1930s) and the construction techniques were cutting-edge. However, they faced challenges such as the turbulent currents, the hurricane winds and the dense fog in the area. Not to mention its proximity with the San Andreas and Hayward fault. One of the solutions was to make the structure of the Golden Gate something dynamic and not rigid, which allows it to better deal with wind and tide (literal). In addition, it is designed so that the two towers absorb the tension generated by the passage of vehicles through the suspension cables. One of those towers had to be built in the middle of the open ocean, something exceptional at the time. High turnover and a lot of security. Although its construction is carefully documented and there is an extensive graphic archive, there is no record of how many people worked on its construction beyond the fact that there were 10 contractors with their respective subcontractors, there was a lot of turnover (note: we were in the context of the Great Depression) and that at the peak of the work there were hundreds of men working, with critical roles such as structuralists, divers, spinners to weave the cables and painters and riveters. Unfortunately, 11 people died during this imposing construction. And this despite the fact that its chief engineer, Joseph Strauss, stood out for its commitment to job security: They installed a safety net under the bridge that would save those 19 workers who became part of the Halfway-to-Hell club (halfway to hell). 200 people for maintenance. Although the exact figure is unknown precisely due to the turnover and number of contractors, there are estimates which point to figures between 4,000 and 8,000 workers who participated directly in the construction between 1933 and 1937, which seems plausible. What is most striking is that for its maintenance about 200 workers are needed among engineering professionals, metal workers, painters, mechanics, electricians, communications technicians, street and garden maintenance, among others. The maintenance team. In the age of AI and automation, San Francisco Bridge Maintenance pulls trades with a multidisciplinary team led by a captain who oversees patrol activities 24 hours a day. As a curiosity, since 1937 there have been 11 captains. As a summary, these are the main positions and their functions: Painters and metal workers. They work at height and in confined spaces. They are responsible for painting, sandblasting old paint, and repairing corroded steel and rivets. Structural Engineers: They carry out visual and sensor inspections of each of the thousands of rivets and cables, in addition to ensuring the operation of the machinery. Safety and Traffic: With a flow of 100,000 vehicles daily, accidents and breakdowns are the order of the day. It is a 24/7 operational service to avoid collapsing the city. Why so many people. As we have seen in the previous point, maintenance logistics is specialized and has a certain complexity being at altitude, it requires always being available and the environment is aggressive. Paint the Golden Gate It has its own, hence it has its own section within the bridge website. To begin with, it is not painted every so often, but rather it is painted continuously and in parts. And maintenance is selective and based on priority: it is a battle against corrosion. The combination of the humidity of the Pacific and its high salinity is a ticking time bomb for steel. Although they chose the International Orange tone because of how well it integrates with the environment and its visibility, this paint protects the steel from UV rays and humidity. On the other hand, inspections of its expansion joints and seismic dampers are frequent to ensure that it can flex without breaking due to vibrations and earthquakes.

young people are alone and no longer want to flirt like before

by

I’ve never been much into dating apps. I tried it once—shortly, just enough—and it overwhelmed me. Too many faces, too many conversations started at the same time, too much feeling of choosing men as if they were menu options. I closed the app and thought maybe the problem was mine. For years, that feeling seemed to remain in the minority. The dominant narrative was different: if you weren’t in the apps, you were missing something. He matches as a gateway to an active, modern and socially validated sentimental life. But something has begun to break in that story. And it is not their critics who say it, but the companies themselves that built the business of swipe. Today, dating platforms recognize that young people still want to love, but they feel less and less capable of starting a relationship. Not because of a lack of desire, but because the process has become emotionally burdensome, socially exposed, and psychologically demanding. In the midst of a hyperconnected generation, the result is not more love, but more loneliness. According to a report Elaborated by Match Group with Harris Poll and The Kinsey Institute, 80% of Generation Z believe they will find true love one day, more than any other generation. However, only 55% feel ready for a relationship right now. This distance between desire and action is what the company has called the readiness paradoxor “paradox of readiness.” Contradiction is key to understanding the current moment. Young people want relationships, but they don’t know when—or how—to start them. The same report notes that almost half of Generation Z say they are not ready for a relationship right now and that 75% are in no rush to get into one. As I explained to Fortune Chine Mmegwa, head of strategy at Match Group, the process becomes a cycle that feeds on itself: very high standards of emotional preparation lead to waiting; waiting, loneliness; loneliness, to the desire for connection; the desire, the fear of not being ready. The result is not detachment, but paralysis. Hyperconnected loneliness This paralysis does not occur in a vacuum. It occurs in a context where youth loneliness has skyrocketed, even among people with an active social life and constant presence on networks. a study published in PLOS One defines this phenomenon as a “social ambivalence”: young people surrounded by people who, even so, feel deeply alone. In Spain, data from the State Observatory of Unwanted Loneliness show that Almost seven out of ten young people admit to having felt lonely recently, regardless of the number of friends or followers they have. The amount of interaction does not compensate for the lack of emotional depth. Have likes It is not equivalent to feeling accompanied. The Match Group Report confirms this feeling where more than 50% of Generation Z say they feel lonely despite having online connections. And, unlike previous generations, many admit that they seek connections not so much for love as to avoid loneliness, something that later generates guilt or the feeling of entering a relationship “for the wrong reason.” The fear is not of the appointment, it is of public failure Added to this emotional fragility is a decisive factor: social networks have changed the very way of starting a relationship. An appointment is no longer requested. Instagram is requested. And many times, everything stays there. Follow each other, watch stories, react with an emoji, observe for weeks—or months—without taking a clear step. A permanent phase of trial and error that reduces risk, but also blocks progress. When a relationship seems to be moving forward, the pressure doesn’t go away; moves to the public showcase. According to data collected by Fortune From Match Group reporting, nearly half of Gen Z’s relationships begin with a soft launch on Instagram —an ambiguous photo, a story without context— compared to 27% of the population as a whole. He hard launchon the other hand, is perceived as a serious commitment by 81% of those who have done it. Making a relationship official is no longer just another phase, it is experienced as a symbolic contract. Fear of public failurehaving to delete photosmanaging explanations, exposing oneself to judgment—works as a brake before even starting. Better not to start anything than to have to undo it in front of everyone. Match Group describe this climate as a real “performance pressure” applied to one’s love life. This retreat is not exclusive to dating. As we already analyzed in XatakaGeneration Z is consciously reducing their public exposure on social media: fewer posts, more private messages; Less footprint, less risk. This climate is reinforced by a change in the ways of dating. How to collect Business Insidertraditional flirting is on the decline: asking for a profile has replaced asking for a coffee. Dating apps and the pandemic have weakened the “muscle” of talking to strangers in person, creating more social anxiety. The result is not rejection of contact, but rather a passive, prolonged and unresolving approach. Some experts clarify, however, that it is not so much a loss of skills as a code change. Generation Z is more direct with its boundaries and expectations, and less tolerant of prolonged ambiguity. The indefinite is tiring. The confusing is exhausting. That fits with report data Year in Swipe 2025 of Tinder, where there is a growing rejection of “minimum effort” and ambiguous signals. Trends like clear-coding or the loud looking —explicitly saying what you are looking for and from where—reflect that desire for emotional clarity in an ecosystem that, paradoxically, pushes us to say nothing and wait. Apps adapt: ​​less pressure, more context Faced with this scenario, dating applications have decided to change their approach. They no longer sell the promise of hooking up quickly, but rather on reducing the anxiety of the first contact. Tinder, owned by Match Group, has been the most explicit in this turn. Last year he launched Modesa system that allows you to choose how and from where to meet people: classic mode, … Read more

A town in Burgos has resorted to a desperate idea to get people to stay there: paying them for food

by

Cardeñajimeno is a small town from the Alfoz de Burgos region, in Castilla y León, where just under 1,200 residents live. Its city council is not willing to let that figure drop and has decided to tackle the challenge of depopulation by making it as easy as possible for its inhabitants, especially the elderly. As? Cooking for them and bringing food to their doorstep. Whatever it takes to escape from an “emptied Spain” that has been going on for decades. expanding your footprint through the peninsula, with the challenge what that entails. Objective: establish population. Spain may move in record population numbers, with 49.4 million of censuses as of October 1, 2025, but that does not mean that the entire territory is going through its best demographic moment. On the contrary. The ‘record Spain’ also hides a ‘Spain emptied’ that has spent decades spreading its footprint across the peninsula, feeding on municipalities that have been gradually depopulated. I warned him Before the pandemic, the Spanish Rural Development Network (REDR) recalled that in a matter of two decades the number of towns with less than one hundred neighbors had increased by 60%. A similar message The Galician Accounts Council was launched in 2024, remembering that a hundred towns in the region face the risk of becoming ghost towns. How to avoid it? That’s the million dollar question. In an attempt to fix the population and not swell the map of emptied Spain, over the last few years the administrations have racked their brains looking for solutions. Some offer financial aid to attract new residents. There are town councils that they are taking charge of local businesses (gas stations or grocery stores) to prevent their neighbors from being left without basic services. And not long ago we even told you about a remote town in the province of Soria that reached offer house and business in an attempt to attract new blood. Making it easy. In Cardeñajimeno (province of Burgos), they have gone one step further to make it as easy as possible for its inhabitants and prevent the elderly from packing their bags to move to larger towns. As? Taking care of your diet. The news has advanced it Burgos Connectwhich on Saturday revealed that two populations in the region “will pay for food” to their elders to stop the depopulation that is shaking part of the community. “Encourage permanence”. The towns in question are those that make up the municipality of Burgos: Cardeñajimeno and San Medel. A few days ago its Consistory launched a tender to look for professionals interested in providing a “catering service to elderly people” residing in the town. The goal? “Promote the elderly person’s permanence in their usual environment and avoid depopulation.” In other words, provide the necessary means so that no elderly person from Cardeñajimeno or San Medel is forced to move to Burgos or another larger town in search of comforts. But… Is it necessary? The case of Cardeñajimeno is interesting because it shows that rural Spain not only faces the challenge of depopulation, it also deals with aging. Although the situation of the town is far from being critical (the INE counts there 1,185 registeredbelow the 1,205 in 2022, but significantly above those recorded two decades ago), it does not escape the trend of the rest of Spain. 20% of its population is over 60 years old and dozens of octogenarians and nonagenarians reside in the town. “Nutritional well-being”. With the new service, the City Council wants to “provide nutritional and physical well-being to all those elderly who, given their special situation, require it.” To achieve this, it even contemplates that the company prepares “different diets” adapted to users with special needs. For example, diabetics or people who need crushed food. The base tender budget is 16,500 euros for one year, with a maximum price per menu of 9.6 euros, but the specifications also clarify that the final price will depend on the acceptance of the service, its users and how much food they request. On the State contracting platform the budget Estimated is 30,000. In other locations are already offered similar benefits.

148 elderly for every 100 young people

by

Spain may move in record numbers of population, but that does not mean that its demographic engine is oiled. On the contrary. If the census grows it is thanks to immigration. The latest INE studies show that every time fewer babies are bornexactly the opposite of what happens with life expectancy (continuously increasing) and deaths (stagnating). With these data on the table, the latest red light that has been lit in the national demographics is less surprising: the aging index has risen so much that it already marks a historical fact. This is not good news for the country’s labor market. What has happened? That Spain is increasingly a country of elderly people. It is no surprise, but that does not mean that the data that just published Adecco Foundation is striking. In its report ‘Aging and occupational ageism’ it reveals that in 2025 the “aging index” climbed to 148%. What does that mean? That in Spain there are now 148 people over 64 years of age for every 100 under 16. Just a year ago that same index was 14.23% and if we go to the end of the 90s it was at 99.8%, which means that almost the same proportion of elderly people resided in our country as those under 16 years of age. Is it important information? It is certainly illustrative. Both for its most obvious reading (148 people over 64 years of age for every 100 young people), and for the trend it suggests. Between 2024 and 2025, the index grew 5.7 percentage points, the largest increase since Adecco studied the phenomenon. As if that were not indicative in itself, the 2025 result shows that the country is still deep in the aging curve that it has been tracing for years. Between 2003 and 2009 (coinciding with a period of intense migratory flow, prior to the financial crisis) the proportion of children and adolescents over the elderly seemed to recover, but this trend soon stopped and has not been corrected. Is this a surprise? No. The Adecco study is new, but it is based on previous data from the INE that already suggested the same idea. In November the statistical institute published a balance on ‘Natural Population Movement’ in which three major trends were made clear. The first, the decline in the birth rate. In 2024, 318,005 births were registered in Spain, 1% less than in 2023 and far from the 427,595 recorded by the INE in 2024. On the contrary, life expectancy has continued to grow since the pandemic to stand at 84.01 years. If we add to the above that the number of deaths has also remained stable, the conclusion is clear and connects with Adecco’s calculations: fewer young people, more old people, greater imbalance, tipping the balance in favor of the latter. If at the beginning of the century there were practically the same number of people of retirement age as there were young people under 16, today it is much easier to meet the former on the street than the latter. Does it happen throughout the country? No. Not at least with the same intensity. Adecco has dedicated itself to calculating the aging index of each autonomous community and its results demonstrate the profound differences that exist at the territorial level. The oldest region is Asturias, with an indicator of 265.3%. That is, there are 265 people over 64 for every 100 under 16. Galicia (231.6) and Castilla y León (230.7) follow in the ranking. At the opposite pole are Melilla (60.4), Ceuta (74.5) and Murcia, which debuts in the ‘red zone’ with an index of 102.7%. And what does it matter? With the index Adecco does not want to cover only a statistical curiosity. Its objective is to launch a warning that directly affects the economy and the productive capacity of Spain: the pool of young population, who is about to join the labor market or will do so in the short or medium term, is increasingly lower compared to the sector of the population about to retire or who is already collecting their pension. And that is a problem. “Spain faces a structural paradox: while the population ages and the workforce becomes older, the labor market continues to underutilize professionals over 45 years of age and perpetuate the barriers that limit their employability,” warns Adecco Foundationwhich recalls that long-term unemployment affects 34% of the unemployed in Spain, a percentage that skyrockets to 48.5% if we talk about those over 45 years of age. To do? The organization is clear: rethink deep-rooted ideas. “The aging rate does not stop growing and this demographic reality places our country before a structural challenge that does not allow further delays,” reflect Francisco Mesonero, general director of the Adecco Foundation. “In this context, occupational ageism is revealed to be an obsolete phenomenon and a profound contradiction. Spain cannot afford to do without millions of older professionals.” There are those who warn in any case that Adecco’s calculations must be handled with some caution for a simple reason: it is based on two very large, different population groups and in which diverse realities are mixed. “We have a new old age that is neither short nor homogeneous and it must be conjugated in the plural because we cannot put a 64-year-old and an 85-year-old in the same bag, just as a 15-year-old cannot be equated with a 35-year-old,” commented recently in The Vanguard Dolores Puga, demographer and CSIC researcher.

Most people take creatine for the gym. It is actually really useful against insomnia.

by

for a long time Creatine has been seen as a supplement intended for people who go to the gym to have a good muscle. However, this is changing completely to recommend that anyone take creatine for the many benefits of taking creatine to improve cognitive functions for example. Now, it is also being seen that it has a great component for the quality of life in people who suffer insomnia. Sleep deprivation. The human brain represents only 2% of body weight, but consumes 20% of our body’s total energy. The main cfuel it has is ATPthe currency we use, and its ability to quickly resynthesize it determines our mental agility. But when there is sleep deprivation, energy levels drop and with it attention, memory and mood. This is where creatine comes in, as a large study published in Nature in the year 2024which changed what we knew about acute creatine supplementation in anyone. In this case, the researchers demonstrated that a single high dose of creatine is capable of reversing the cognitive deficit caused by little sleep. The results. Specifically, after 21 hours of wakefulness, the subjects showed a significant improvement in processing speed and working memory from taking creatine. Furthermore, one of the effects of stopping sleep is brain acidification. In this case, creatine acts as a buffer, preventing drops in pH and positively altering the relationship between key metabolites such as phosphocreatine and inorganic phosphate. A discovery that complements the classic 2006 study which already indicated that doses of 20 grams a day for a week mitigated the deterioration in prefrontal cortex tasks and improved mood and balance after 24 hours without sleep. Neuroprotection. As we age, the efficiency of cellular energy production decreases, which is why science is focusing on creatine as an agent. anti aging powerful. Something that is especially focused on women who are in perimenopause and postmenopause, where the protective effect of estrogens has been lost. Of course, there is an important change in the dosage, since while the standard dose is 3-5 g, women over 40 may need between 8 and 10 g/day to see notable improvements in cognitive function and mitigation of hormonal “brain fog.” Furthermore, in women, in addition to improving cognition, there is also an improvement in the quality of muscle mass, which is a critical factor for longevity. Older adults. A systematic review of 2025 and ESCEO studies directly associate creatine consumption with better cognitive health in adults over 60 years of age. In this case, creatine appears to compensate for the natural reduction of phosphocreatine stores in the aging brain, improving sustained attention and reducing mental fatigue. The new paradigm. In this way, science is advancing to see that creatine is not just a matter of gaining muscle, since the brain is also a great consumer of this energy. The reality we have on the table is that creatine is one of the compounds most tested in humans, with an excellent safety profile even at high doses. But in addition to all this, it is also the property that working memory has, since it is undoubtedly the most tangible benefit that we can have in the case of doing complex tasks that require great mental effort under very adverse conditions.

There are people obsessed with consuming magnesium as a supplement when the best way is to put it in your diet

by

We live in the era of biological optimization, where The strange thing without a doubt is not taking dietary supplements from the supermarket such as magnesium, collagen, calcium, various vitamins… Magnesium in particular is sold as an almost magical way of sleep betterreduce anxiety and recover muscle. But the truth is that we are forgetting the most important thing: We have all this in food. The reminder. With so many food supplements (which often do not come cheap), sometimes we forget that we have these nutrients in the supermarket in different presentations. This is something in which Doctor Federica AmatiChief Nutritionist at ZOE Science & Nutrition, has put its finger on the sore spot of the supplement industry: For the vast majority of the population, there are plenty of pills and no food. Why magnesium matters. There is an obsession with taking this mineral, and the reality is that it makes sense because its functions are critical for our body to function correctly. Its fundamental role in many metabolic reactions of the body makes it essential for human survival, since without magnesium we would literally be extinct. And it is no wonder, because beyond being used to prevent cramps, it has important functions in energy production, DNA synthesis, metabolic control such as glucose levels, and also structural function by allowing bone to develop. Given its importance, the consumer logic seems simple: “If it’s so important, the more you take, the better”. But this is where science has to put the brakes on because a large amount does not always equal better performance. The best foods. One of the positions that we can have on the table right now is that magnesium supplements (and even others) are not necessary, unless it is known that there is a deficit. All this because it has a big problem: they are isolated. The problem with supplements is that they are isolated. NIH Office of Dietary Supplements (ODS) emphasizes that the food matrix It is irreplaceable. When you get magnesium from an almond or spinach, you’re not just ingesting the mineral, you’re getting fiber, phytochemicals, and other micronutrients that work together and that no pill can fully replicate. The daily doses. The official recommendations today indicate that the minimum levels of magnesium They are not unattainablesince for adult men between 400 and 420 mg per day are needed, while for women between 310 to 320 mg per day is sufficient. Low figures mean that they cannot be easily achieved with food by adjusting the shopping list without going to the pharmacy. Where can it be found. If the goal is to reach 400 mg daily, the strategy is not to look for supplemented foods, but to go back to the basics. In this case, science points because the food where we have the greatest amount of magnesium are seeds and nuts, where we find almonds, cashews and especially pumpkin and chia seeds. But in addition, it should also be noted that green leafy vegetables such as spinach or chard have chlorophyll in their composition, which also acts as a highly coveted magnesium reserve. All this without forgetting legumes and whole grains. Who needs supplements. Logically, they have a site, but it is by no means a universal recommendation for everyone who may have their requirements met with the diet. According to the ODS, there are different groups of people who may require this supplementation (under medical supervision). These are the following: Gastrointestinal disease such as celiac disease where nutrient absorption is compromised. Type 2 diabetes, since its pathophysiology causes a decrease in magnesium. Chronic alcohol consumption. Elderly people where absorption is naturally decreased. In these specific cases, the evidence indicates that supplementation can help improve parameters such as sleep quality or anxiety, but because they have an absorption problem. A previous visit to the doctor. Before starting supplementation of any type, it is best to go to your primary care doctor to verify in a blood test the nutritional deficiencies that you want to counteract. And our body does not store these minerals, meaning that anything taken in excess has no effect whatsoever. In Xataka | Which dietary supplements really work and which don’t, in a great graph

There are people so against sleeping that they have even made caffeine patches. It’s a bad idea

by

If the 90s were the decade of nicotine patches to save the lungs and the 2000s that of transdermal contraceptives, 2026 has given birth to a different and more revealing obsession: wellness patchmania. If we thought we had seen it all in the universe of digital self-care —tapes to cover the mouth and sleep better, stickers to lose weight effortlessly or nighttime facial bandages that promise wake up with botox effect— the last frontier is here: patches to have energy, concentrate more or sleep better or reduce appetite. Simply peel off a small sticker, adhere it to your skin, and trust it to do its job. The so-called wellness patches or wellness patches are transdermal adhesives that promise to release active substances through the skin for several hours. As brands explain and advertising campaigns, allow you to avoid pills, bypass digestion and offer a slow and constant release of ingredients such as caffeine, berberine, B vitamins, melatonin, magnesium or plant extracts such as ashwagandha. According to The Guardianit is a market that is increasingly saturated with products that promise to treat “the most common symptoms of everyday life”: fatigue, stress, lack of sleep, menstrual discomfort or low mood. Many of these patches are sold in bright colors and designs designed not only to be worn, but to be seen. Well-being stops being something intimate and becomes a visible sign. The phenomenon is not new in medicine: nicotine patches, contraceptives or some hormonal treatments have been used for decades with proven effectiveness. The difference, As several experts point outis that these medical patches work because the molecules they release are suitable for passing through the skin and because they have passed rigorous clinical trials. In the world of wellness, that requirement disappears. An increasingly tired society The appeal of these products lies more in their aesthetics and comfort than in their effectiveness. In other words, there is no need to swallow a pill, prepare a drink or change routines: just stick something to your skin. As pointed out in The Atlanticpatches fit perfectly into a culture obsessed with constant self-optimization and hack vital. Furthermore, by being visible, they turn the user into a brand ambassador: they generate conversation, social validation and the feeling of doing something for their own health. However, the scientific consensus is quite clear. As Michelle Spear explainsProfessor of Anatomy at the University of Bristol, the skin is not designed to absorb substances, but to block them. Its outer layer, the stratum corneum, acts as a wall formed by dead cells and lipids that prevents the passage of most compounds. Only some very specific molecules can pass through it easily: small, fat-soluble and without an electrical charge. Nicotine or estradiol meet these conditions. Many of the substances present in wellness patches such as vitamin B12, minerals such as magnesium or iron, or plant compounds such as berberine are too large or water-soluble to pass through the skin in significant quantities. In other words, if a substance requires high oral doses or even injections to be effective, the probability that a sticker will be able to deliver it in a useful way is very low. Added to this is the lack of independent studies that show that these patches can correct real deficiencies or treat health problems. The problem of “feeling better” Immunologist John Tregoning suggests a key question: How do you measure whether something works when the effect is “feeling better”? Tiredness, stress or concentration are deeply subjective experiences, influenced by multiple variables. Sleeping more, changing routines, eating better or simply believing that something will work can alter perception. Beyond the lack of effectiveness, experts warn of possible side effects. From the British environment have collected cases of dizziness and feeling of weakness after using patches with berberine. Added to this are skin irritations, allergic reactions and a false sense of security that can delay seeking medical attention. When the patch is no longer harmless. Caffeine patches are promoted as a gentler alternative to coffee or energy drinks. However, testimonies collected in different media they mention nervousness, difficulty sleeping or feeling overstimulated. The problem is not just the caffeine, but the inability to control the dose: unlike a drink, the patch continues to release it for hours, even when the body no longer needs it. Berberine poses a different problem. These patches are marketed as appetite suppressants or metabolism accelerators, and have even been compared – without scientific basis – to drugs such as Ozempic. The experts remember that there is no solid evidence berberine can be absorbed effectively through the skin or cause significant weight loss. Furthermore, these products are becoming popular in a context of the return of aesthetic pressure and the obsession with thinness, especially among young women. The risk is not only physiological, but cultural: presenting hunger control as something that can be turned off with a sticker reinforces an instrumental and problematic relationship with the body. The patch as a cultural symptom The underlying question cuts across all sources: why do we look for such simple solutions? As Deborah Cohen points outwe are medicalizing normal life experiences. Sleeping poorly, being tired or losing concentration are not always pathologies; Many times they are logical responses to a demanding, hyperconnected and poorly rested environment. However, we live in a culture that prefers shortcuts to rethinking. It is easier to put on a patch than to review schedules, workloads, expectations or rest habits. These products do not promise to change life, but to make it more bearable without questioning it. They function, in that sense, more as a cultural pain reliever than as a health tool. Most experts agree thatif a patch makes someone feel better and does not cause harm, its occasional use is not necessarily dangerous. The problem arises when they are presented as real solutions to complex problems or when they replace basic habits such as sleeping, resting, eating well or consulting a health professional. Perhaps the success of caffeine and berberine … Read more

In 1987 a death was filmed so savage that people had to cover themselves. The trick to achieve it turned RoboCop into a cult work

by

In 1987, the film director Paul Verhoeven gave a twist to action science fiction with RoboCop. In reality, that was a cocktail very much to the director’s liking where there was satire, cyberpunk and police thriller. The difference was that he did not limit himself to telling the fall and rebirth of a hero: he decided to win over the viewer with emotional hammer blows, with a death. so cruel and excessive that it was impossible to look at without feeling uncomfortable. The scene that changed everything. Alex Murphy, the protagonist, appears up to that point as a good cop thrown into a corrupt world, but the film doesn’t have time to build him up calmly, so it does it by the most brutal way: literally, it tear apart in front of the viewer so that, when he returns converted into a machine, he understands that what has been lost is not only flesh, but humanity. Verhoeven explained it with an almost religious and at the same time tremendously cynical idea: “if you want to resurrect Murphy as an all-powerful RoboCop, first you have to crucify him.” And that crucifixion, instead of being symbolic or elegant, is filmed like a physical nightmaredirty and painful, one designed so that the viewer cannot avoid the impact. The slaughter as a narrative. The sequence It is constructed like a public execution, with the criminals laughing in the background, and that is possibly the key to its violence: it is not just that it unlockis that along the way they humiliate him, turn him into a broken toy, and torture him as if the gang were enjoying the show. The scene is escalating until it seems impossiblewith the protagonist trying to understand what is happening to him while his body stops obeying him, and the band acting like real madmen. There is the moral trick of the director of RoboCop: The villains were absolutely grotesque, yes, but the film removes any sympathetic veneer from them and turns them into a total social menace. Thus, when the final shot arrives that puts an end to the execution, the viewer is no longer watching the typical “80s action” film, he is seeing the point of no return that makes the entire film, from that minute on, a story. of loss and revenge. The old school of effects. It is impossible to talk about this classic without mentioning what makes it unique. The how was filmed: no less than under the orders of the legendary Rob Bottin with an artisanal obsession that today seems unthinkable based on meticulously designed prostheses, molds, fake parts and physical tricks. In order for the mutilation to work without putting the actor at risk, a a fake hand From a real mold, it was reconstructed in fiberglass and divided into sections so that it could be “popped” with compressed air and stage blood without the need for explosives near the face. It wasn’t just an effect, it was a device home engineering: internal blood tubes, pressure control, parts that could be assembled and disassembled, and a repeatable explosion pattern to always nail the same result. “Death” was also filmed with a staging designed to hide the real and sell the fakewith raised floors, holes through which to put the real arm under the stage, and a member of the team moving from below a false arm attached with Velcro as if it were a living limb. The underground trick. Plus: Murphy’s death is supported by a secret choreography that the viewer never saw: operators out of shot, hidden mechanisms and an absurd number of hands working to make a second of screen seem like an organic nightmare. Not only that: a foam arm in disguise with a police uniform, a metal structure to hold it, hinges at the “elbow” and even a support anchored to the false floor so that everything could resist the violence of the effect. While the actor was dying and staggering above, below there was a team of professionals pumping blood by hand and adjusting compressed air. Even the shots that “break up” the armor were reinforced with simple but brilliant physical details, such as small charges of talcum powder to simulate fragmentation, a very cheap solution that, in camera, added texture and turned the scene into something tactile, with dust, impacts and material that seems to fall off the body. The Peter Weller doll. Another stroke of genius came with the moment of the auction: for a final shot that in the released version lasts a sigh, a Murphy’s full torsoa sophisticated doll with a latex face made from a mold of the actor, an internal fiberglass skull and mechanisms to move the neck, jaw and body. It was not a static mannequin, it was a creature manipulated by cablescapable of opening his mouth in a silent scream, leaning, trembling and reacting to the shot as if there was still life inside. The execution was designed so that the back of the head “jumped out” with a controlled explosionwith pieces pre-cut to break in a specific way and with the interior prepared with blood and soft fragments, so that the horror felt mechanical but compelling. In addition, the “sweat” detail was added with water sprayas if the doll was breathing for the last time, and a motor with vibration so that the body seems to tremble with fear, an almost obscene trick due to its human nature that returns to artifice. Censorship as an enemy. The most incredible thing is that, even so, what was seen in the rooms was a cropped version. RoboCop’s violence clashed head-on with the rating system of the time, and the film was given an X rating several times, forcing reedit, cut and sacrifice material until a commercially viable qualification is achieved. Paradoxically, the cut that helped save it was one that its own creators considered “shabby” or too obvious, the moment in which Murphy’s arm flies off pulled by a … Read more
