The super Niño of 1877 wiped out 4% of the world’s population. The one that is already beginning to form promises to be worse, but what does that mean in 2027?

by

In the last week, El Niño has become suddenly real. Media like Washington Post, BBC or countless media in Spanish have begun to compare what is coming to us with El superNiño of 1877, the event that “wiped out 4% of the world’s population.” And, stated this way, it is no wonder; The story is simple: “a Child Godzilla is coming and no one knows if we are ready.” That is why it is important to know what exactly we are talking about and if, in short, “we are all going to die.” How serious is the matter? As we said a few days ago, between March and May the reliability of ENSO forecasts is usually worse than normal (because the equatorial Pacific anomalies go through their transition phase). That makes everyone go with “lead feet”; but the data is worrying. Ben Noll of the Washington Post broadcast on May 8 that the North American Multi-Model Ensemble projected “the strongest El Niño on record” between October 2026 and January 2027, with a peak of +3.1 °C in November. They are big words. Above all, because the ECMWF is along the same lines. In the words of Diego Restrepo, “El Niño is rapidly intensifying, and now 8 out of 10 models point to a super event and four project the strongest one on record.” And this looks like 1877? That is Noll’s thesis and it has been repeated a lot in recent days. However, the comparison is misleading. First, because, although the models are pointing to a historical ENSO, they are still models. That is, we still have no idea what is going to happen. And, to be strict, until the models recover their full potential in June, we will not know well. Second because, as argued by Kimberley Reid, from the University of Melbournethe intensity measured in the central Pacific does not translate linearly into impacts. Taking into account everything that has changed in this century and a half at a climate level, the impacts may be completely different. And thirdly because El Niño of 1877 was not the cause of that catastrophe. Yes, it is true that he set the conditions for it to occur but, as noted Mike Davis in “Late Victorian Holocausts”what killed throughout that quarter of a century were colonial policies. And what happened in 1877? A strange combination between a superNiño, the Indian Dipole and a tremendously warm North Atlantic between the years 1876–78 caused a global drought. The problem is that, in a world governed by imperialism, grain exports did not stop and, as local resilience mechanisms had been dismantled, a famine occurred that killed some 50 million people. But the consensus is clear: no matter how intense El Niño was, it caused the problem of its management. And that, although it may not seem like it, is good news. A few years ago the World Meteorological Organization (WMO) published a report with a clear warning: “climate-related disasters” have increased since the 1970s. Specifically, they have multiplied by five over the last five decades. According to their calculations, in the 1980s, 1,400 incidents were recorded – their tables include extreme weather, climate and water phenomena – and in the 1990s, just over 2,200. In the first decade of the 21st century, 3,500 were reached and during the last decade, which spans from 2010 to 2019, it was close to 3,200. Curiously, this increase in the number of disasters has coincided with a decrease in the number of victims. The WMO data is clearalso: from more than 50,000 deaths in the 1970s (incidents basically related to climate and water are taken into account) it went to less than 20,000 in 2010. From an average of 170 a day in the 70s and 80s, it dropped in the 90s to less than a hundred a day and to 40 at the beginning of the 21st century. What will happen? As Restrepo also points out“despite having more information and knowledge, today we have warmer oceans, much more vulnerable ecosystems and collapsing biodiversity. This could generate impacts on health and risks for food, water and energy security.” However, we are more prepared and more importantly we have time to prepare. The ball is in our court.

The current that warms Europe will weaken by 51% before the end of the century. And Spain, according to experts, is already beginning to notice

“The 5% chance just became 50%.” This quote from Stefan Rahmstorf, the world’s leading expert on the collapse of the AMOC, describes the change it introduces the study just published by the University of BordeauxIt’s this April 15th. But the story goes beyond the number: it is the latest installment of the great climate debate of the decade. A debate that, whoever wins, we are all losing. What exactly is AMOC and why do we care? The Atlantic Meridional Overturning Circulation is the North Atlantic branch of the thermohaline circulation. Since the sun does not heat the sea equally everywhere and freshwater flows reach the ocean at very specific points, this is the basic mechanism by which the oceans balance differences in temperature and salinity. The AMOC is a good example of this regulation. After all, as explained from AEMETit is an “Atlantic basin-scale north-south ocean flow that begins with cold sea water sinking to the bottom off Greenland, subsequently flowing south, and being replaced by warmer water flowing at the surface from the south, transferring heat from the tropics to the east coast of North America and the west coast of Europe.” Therefore, it is a key mechanism and if it stops, as studies began to say a decade ago, the problems for Europe would be enormous. Huge? “Without it, Western Europe and eastern North America would cool significantly, with a host of potential adverse effects,” said Sánchez Laulhé. We talk about a “widespread cooling throughout the North Atlantic and northern hemisphere in general” that would collapse the temperature in Europe would drop several degrees and cause a “strengthening of winter storms, with more and more powerful explosive cyclogenesis” and a “greater proportion of precipitation falling in the form of snow throughout Europe.” However, scientists do not fully agree. In 2021, the IPCC said the AMOC was “unlikely” to collapse. In 2023, the Ditlevsens not only said that it was a probable scenario, but that they set the first date for the collapse. In 2024, 44 signatories They asked to take the problem seriously. But in January 2025 Terhaar, Vogt and Foukal said which, in short, had not weakened since 1063. Now, the University of Bordeaux states that the AMOC will weaken by around 51% by the end of the century with a confidence level of 90%, under the intermediate emissions scenario. What can already be seen. French researchers they are right in which the most recognizable observational signal of the weakening of the AMOC is the “cold spot” of the subpolar Atlantic south of Greenland. In the midst of climate change, “the only point on the planet that has cooled in the last century.” However, we are also not clear what that really means. And there is the key. So will Europe freeze? Probably, but that’s not what’s interesting. Throughout the history of the Atlantic it has been passed many times. The question is whether it will be soon, if it will be our fault, if we can avoid it and what consequences it will have. Be that as it may, Spain will not be the most affected, but it will be. It is being. Stefan Rahmstorf, for example, said last year at the Autonomous University of Madrid that “the slowdown of the AMOC is already having impacts in Spain.” You just have to know how to read the signs.

There are only 66 cases in the world and science is just beginning to understand it

Night rest can be interrupt due to many factorssuch as the need to go to the bathroom constantly to drink water before going to sleep, but there are other cases, such as painful sleep erectionswhich right now is emerging from ignorance, and that is why every time you get to know more of this problem which, fortunately, is quite infrequent. What is it? Although you may think that this is a problem related to the penis, the truth is that it is classified as a parasomnia. And it is no wonder, because what happens to the man here is that he has multiple erections during the night while he is in the REM phase of sleep that are so painful that it makes you wake up with a jump out of bed. But the curious thing is that the problem does not lie in the penis tissue itself, but rather clinical reviews point out that this disease is closely linked to hypertonicity or contracture of the bulbocavernosus muscles of the penis and the pelvic floor. Added to this are alterations in the central nervous system, such as instability during REM sleep, a peak in activity of the sympathetic nervous system and abnormal processing of pain and hormonal stress signals. It’s a challenge. At the level of cases diagnosed with this problem, the reality is that we speak of a “phantom disease” since it barely there are 66 cases documented worldwide, and there are almost no articles in the medical literature. This is something that translates into a situation of underdiagnosis, since in daily practice specialists see very few cases throughout their career. As a result, patients suffer a medical journey that delays diagnosis for years, and in desperation, and in the absence of answers, many end up assuming erroneous self-diagnoses based on chronic stress or prostatitis. Science tries to advance. Historically, the lack of cases made it difficult to create treatment protocols with the steps that doctors had to follow to solve the patient’s problem. However, recent clinical research has shed light on highly effective therapeutic approaches. That is why right now the use of muscle relaxants such as baclofen has proven to be a turning point for patients, since by relaxing the muscles of the penis an improvement is achieved in patients with this problem. In addition, diseases that are below this problem should also be looked for, such as sleep apnea or insomnia in general, which may be related to this pathology. Although there is still much to be done to investigate this disease, which a priori is quite unknown.

The price of diesel is beginning to fall, but it is still far from what it cost before the war: what can we expect now

by

Last Wednesday, April 8, the announcement of a temporary ceasefire two weeks between the United States and Iran, conditional on the partial reopening of the Strait of Hormuz, triggered an immediate reaction in energy markets. The barrel of Brent oil accumulated a weekly drop of 13.77%the highest in nine months, placing the price more than 15 dollars below the level at which it was trading just a week before, when it was still above 110 dollars. That shock has arrived, with a dropper of course, to Spanish gas stations. What you see at the pump right now. On Friday, April 10, the average price of diesel in Spain was around 1.87 euros per liter, with a drop of 1.67% in the next 24 hours compared to the previous day. A still timid drop if one takes into account that diesel was quoted at an average of 1,881 euros per liter during the week of March 27, the highest price since it came into force. the fuel tax reduction approved by the Government. And filling a 55-liter tank of diesel cost about 103 euros, according to data of that same period. Why oil has fallen. The key is in the Strait of Hormuz. Around 20% of the world’s oil passes through it, and its blockade since the beginning of the war had skyrocketed crude oil prices to almost $146 per barrel at the worst times. When talks between the US and Iran were announced for the start of a truce, the price plummeted from $110 to $94 in a matter of hours. Why does it take so long to be noticed at the gas station? Here comes into play what we have been explaining these days in our coverage: the rocket and feather effect. When oil rises, the price of fuel at the pump reacts almost immediately; when it goes down, the correction arrives weeks late. Distribution companies quickly transfer crude oil increases because they anticipate that replenishing fuel will cost them more. But when the price drops, they claim to have stock previously purchased at higher prices, thus delaying the drop. According to Bloomberg Linein Spain the movements in the price of gasoline have been minimal, even upward at times, with variations of less than 1% despite the sharp decline in crude oil. How long do you have to wait? The deadlines vary depending on the source, but there is consensus that the drop will not be immediate. Just like they count From Autopista, the most favorable purchase prices take between 14 and 28 days to reach gas stations significantly, and after four weeks. But of course, all this in case nothing else happens that affects the price, something that we unfortunately do not know about. The tax reduction what we have in Spain. The Government approved fiscal relief measures that have acted as an extra cushion. The first vice president and Minister of Economy, Carlos Body, wait that the fall in oil prices “will also end up resulting in a drop in fuel prices”, after the reactivation of maritime activity in the Strait of Hormuz. However, the European Commission has warned Spain that the reduction in VAT on fuel from 21% to 10% has failed to comply with Community regulations, which adds uncertainty as to whether this aid can be maintained. What can happen from now on. The most favorable scenario, and also the most fragile, depends entirely on the ceasefire holding. Matt Smith, of business analytics firm Kpler, warns that “there will be a lot of reluctance and caution when passing through the strait because it seems that Iran will still be patrolling it,” which will delay the normalization of maritime traffic and, with it, the sustained drop in crude oil. As if that were not enough, oil production in the region fell more in March than in the worst times of the pandemic, and recovering that productive capacity will take time. The American EIA (Energy Information Administration) foresees that the price of crude oil could begin to moderate in the second half of 2026, as long as the international situation stabilizes. But there is no guarantee. What we must not lose sight of. Although the current trend points to a downward correction, current prices are still much higher than before the conflict. The price of fuel in Spain had been relatively stable at the beginning of 2026, with gasoline at around 1.45-1.50 euros per liter, before the escalation of the war changed everything abruptly in March. Returning to those levels is not something that will happen overnight, so for now it seems that we will have to stay alert to learn more information about the situation.

France has begun to retire Windows from its administration. It is the beginning of his divorce from Microsoft, Google and Amazon

by

Digital sovereignty in Europe has gone from being a theoretical concept to something increasingly tangible and desirable with respect to the technology we consume. It is no longer just a trend that is increasingly more individual people are tryingbut has also become an object of desire for administrations and companies. The path to becoming independent from big tech in the United States is not easy and while there are startups like Mistral who gets rich in the processthere is a state that has decided to take a brave step forward: France. In a global environment where data and infrastructure are geopolitical weapons, the French Government, through the Interministerial Directorate for Digital (DINUM), has launched an aggressive roadmap to regain control over their information systems, thus reducing the hegemony of non-EU technological solutions. And it has started with Windows. The decision. In a high-level inter-ministerial seminar, DINUM together with ANSSI, the State Purchasing Directorate and the DGE formalized the most ambitious commitment to digital sovereignty adopted to date by a Western European power. Or what is the same: France wants to exit the American technological ecosystem in a systematic, planned way and with specific deadlines. It is not an experiment, it is state policy. The guideline is clear: map and reduce dependence on technology suppliers from outside the EU. The measure is not a veto but rather a mandatory transition towards a model where public administration must prioritize local or open source solutions, especially in critical services and sensitive data processing. As has declared the Minister of Action and Public Accounts David Amiel: “ We can no longer accept that our data, our infrastructure and our strategic decisions depend on solutions whose rules, prices, evolution and risks we do not control.” Why is it important. From a systems engineering and cybersecurity point of view, the measure is vital for issues such as protecting against Cloud Act of the United States, the law that allows its authorities to access data stored in American companies regardless of where the servers are located. On the other hand, it guarantees that the state maintains its necessary technical capabilities to operate its own infrastructure without depending on proprietary “black boxes” and to heal itself in the event of a change in conditions or other external problems. But this phased migration is much more than an OS change: it involves dismantling the entire associated ecosystem, certificates and applications designed for Windows. It means rebuilding the digital foundations of the state from the roots so that they function with total autonomy and without foreign parts, without citizens noticing the change on the surface. Context. Our daily personal, professional and bureaucratic lives live in an ecosystem governed by hyperscalersthose technology companies like Microsoft, Google or Amazon that dominate storage and cloud computing. This mention is not random: they alone eat more than 60% of the cloud cake, as Statista collects. The increase in cyber threats and the US technological monopoly in the West and its increasingly invasive turn to the privacy of others have done the rest. France has been maturing the doctrine for years “Cloud au Center“. While the ANSSI audited the dependencies on critical infrastructures, its sovereign cloud was being forged as a real alternative. In addition, the European regulatory framework, with the NIS2 directive wave cyber resilience lawhas created the ideal breeding ground. With tools like TchapVisio, FranceTransfert and Socle Numérique (alternatives to WhatsApp, Teams, WeTransfer or Microsoft 365, respectively) France no longer only has a plan, but a real operational base on which to scale. The plan towards sovereignty. It is neither a toast to the sun nor does it have vague and diffuse measurements or distant dates, but concrete, tangible movements and which is either already being implemented or is scheduled to be completed before the end of the year: DINUM abandons Windows and migrates its jobs to Linux. It is the first central State agency to do so. Already underway. Migration of 80,000 agents from the Caisse Nationale d’Assurance Maladie (equivalent to Social Security) to sovereign tools: Tchap, Visio and FranceTransfert. Already underway. Migration of the health data platform to a reliable European solution. Scheduled for the end of 2026. Duties for each ministry: present a dependency reduction plan, which includes databases, antivirus, AI or collaborative tools. For this fall. Yes, but. France has a basic skeleton and a legal framework, as well as public-private coalitions to accelerate the transition through concrete and measurable public commitments. But it won’t be easy. Exiting Windows involves disassembling Active Directory and what is behind it, something that costs a lot of time and money. And migrating 80,000 agents to new tools is not so much a technology problem but rather a problem of implementing new management. Also, go out where. Many European solutions still do not reach the integration, ease of use and capacity (especially in AI) of American big tech, which implies a step backwards in terms of quality. But even if it were possible, moving from a proprietary infrastructure to a sovereign one implies an enormous investment in time, personnel training and data migration. Finally, maintaining and evolving our own infrastructure requires specialized and experienced personnel in a market where talent is scarce and expensive.

In 1955, someone secretly stole Einstein’s brain and stored it in mayonnaise jars. That was just the beginning

by

Seven hours after Albert Einstein’s death, Thomas Harvey was preparing to perform an autopsy on the body at the Priceton Hospital morgue. It was April 18, 1955 and Otto Nathan, friend and executor of the famous physicist, was present: old Albert had become in the “greatest rock star of the 20th century”but he wanted the cult of his person to end there. The pathologist would perform the autopsy, the family would collect the body and secretly cremate it before scattering its ashes in the Delaware River. And so it was. Or, well, that’s what the family believed. Not in my lair. Because inadvertently, without prior documented permission and as quickly as he could, Thomas Harvey removed Einstein’s brain and kept it (in a jar full of formaldehyde). At first he kept it a secret, but no one steals the brain of the great genius of the 20th century to keep it a secret. The news, in a matter of hours, spread like wildfire. And, in fact, on the 20th the New York Times posted that something was happening with the brain. The family panicked, but shortly before publication (and following a fait accompli policy) Harvey managed to convince Hans Albert Einstein, the eldest son, to give him retrospective permission. I imagine Hans didn’t have much room for maneuver: Harvey had the brain in his possession. It was ‘give him permission’ or, perhaps, lose him forever. Einstein’s son set conditions, of course: the main one is that the organ be used for scientific purposes. It wasn’t going to be possible either. Especially because Harvey ‘fell in love’ with the brain and, despite Princeton Hospital’s efforts to have him deposit it, the pathologist repeatedly refused. To the point where, at the end of the year, he is fired. That’s when he took the brain to the University of Pennsylvania and, in a friend’s lab, divided it into about 240 pieces and created 12 sets of slides. Fired and sidelined, Harvey sent 42 of the samples to different forensic experts and neurologists for investigation. That was their plan to return through the front door: the majority did not respond and those who did did not find anything notable. So things really started to go wrong. As a result of his stubbornness, his marriage breaks down. At some point in the 1960s, divorce forces him to take the glass jars containing his brain out of the basement and go to the Midwest. And, deep down, he was lucky. On the one hand, none of the affected institutions wanted to speak publicly about this so as not to compromise their prestige. On the other hand, the courts were not as involved in American life, nor did information flow with the same ease. So found a job in Wichita and he kept the brain in the same refrigerator where he had the beer. Until someone finds it. That someone is Steven Levy, a journalist for New Jersey Monthly. In August 1978, Levy told your brain search of the physical. When she found him in Kansas, Harvey didn’t want to talk, but he quickly loosened his tongue. And, of course, it was a scandal. Throughout the 1980s, he sent samples to some researchers (a Marian Diamond, Berkeley neuroanatomistsent him four samples in a mayonnaise jar), but his ambition was to study it himself in his free time. Things get complicated. Because at the end of the 80s, Harvey lost his license and moved to Lawrence, Kansas, to work in a plastic extrusion factory. He spends his nights getting drunk with William S. Burroughs and welcoming those who come to see him. Convinced by journalists, he did a lot of strange things: from cutting pieces on a cheese board to taking, now in his eighties, a trip to California to talk to Einstein’s granddaughter. Finally, between 1998 and 2007 (when Harvey died), was donating parts from the brain to Princeton Hospital. However, that is the most interesting thing we have been able to get out of this organ of contention: its delirious history is more interesting than what scientists have been able to get out of it. Something that reminds us of a phrase normally attributed to Richard Feynman: “it’s worth having an open mind, but not so much that your brain falls out” (or has it stolen).

In 2025, China installed more wind electricity capacity than the US has deployed in its history. And it’s just the beginning

by

The world faces a textbook climate contradiction: the planet desperately needs cheap, clean energy, but when someone manages to produce it on a massive scale, Western powers put up barricades. We are witnessing a pattern identical to the one that has already shaken the electric car industry. China leads the most competitive green technology, the West fears it and slows it down with tariffs, and, ultimately, the climate ends up paying the bill for this blockade. The figures speak for themselves. According to the latest data published by Wood Mackenzieglobal order intake for wind turbines reached 215 gigawatts (GW) in 2025. This is the second highest figure in recorded history. And the big winners of this milestone were not going to be anyone else. Yes, we are talking about China. While total global volume saw a slight decline of 8% in 2025 – driven by a strategic pause in the Chinese domestic market – the international expansion of Chinese original equipment manufacturers (OEMs) has been relentless. The global consulting firm details that orders from these companies outside their borders skyrocketed by 66% year-on-year, tripling the volumes of 2023. The dominance is almost absolute: eight of last year’s top ten global manufacturers are Chinese, with Goldwind, Envision and Windey crowning the list. But this industrial power cannot be understood without the colossal infrastructure that supports it. China has carried out an engineering feat unprecedented: in 2025 alone, the Asian giant added 542.7 GW of capacity to its electricity grid. In less than half a decade, Beijing has built more energy infrastructure than the United States has deployed in its entire history. From imitation to innovation. The narrative that China only competes by price gouging has expired. The country has made a qualitative leap towards cutting-edge innovation. In these last months we have collected in Xataka the milestones of the Asian country in terms of the construction of large wind turbines in the middle of the sea. This certifies the end of the Western monopoly in emerging markets. While European manufacturers such as Vestas or Nordex maintain leadership in their natural territory, they are losing ground globally to Asian offers with high technical specifications and low costs. For Beijing it is not just about ecology; It is a national security strategy to guarantee the supply of intensive industries, such as Artificial Intelligence, and free ourselves from dependence on imported fossil fuels. This is how they conquer the Global South. Faced with a domestic market that is beginning to mature, the Asian giants have set their eyes on the Middle East, India and Latin America. Finlay Clark, principal analyst of Wood Mackenzie, gives the key to this expansion: Chinese manufacturers are making waves thanks to the rapid deployment of giant platforms of more than 10 MW. These megaturbines allow developers to minimize costs on gigawatt-scale projects. The result is devastating: in 2025, Chinese companies will capture the 95% of regional capacity in the Middle East and Africa. The symbol of this surprise was planted in Saudi Arabia, where the Goldwind company achieved a historic order of 3.1 GW to supply two sites. Furthermore, in its ambition to dominate deep waters—where wind potential is multiplying—China is already manufacturing fully domestic all the key components of its floating platforms. An imminent train wreck. Geopolitics has fully entered the spreadsheet of energy promoters. Wood Mackenzie warns that the policy It is making acquisitions drastically more expensive and complicated. Barriers such as the European Union’s Carbon Border Adjustment Mechanism (CBAM) and the expansion of US tariffs costs are skyrocketing import of steel and heavy components. The market is facing critical tension. On the one hand, regulatory pressure pushes costs up; On the other hand, the profitability of the projects requires increasingly cheaper turbines. Despite this panorama, there are reasons for optimism in the Old Continent: although the intake of offshore wind orders fell by 17% in 2025 due to the restructuring of European tenders, analysts They predict a strong rebound by 2026, boosted by new grant schemes such as the UK’s round 7 auctions. The Western Counterattack. However, China’s apparent invulnerability has cracks. As we detail in Xataka, Beijing suffers from a silent but critical dependence on Western technology. The Chinese wind industry has the muscle to assemble like a beast, but it lacks the “brain”: it needs to import 100% of the logic modules that control the turbines in real time and 70% of the transistor modules for the electrical grid. However, the real obstacle for the West, experts warn, is no longer just capital, but “human bottleneck”: Decades of offshoring have emptied the United States and Europe of engineers and specialized industrial labor. Condemned to understand each other. The energy transition has ceased to be an environmental mission and has become a total geopolitical battlefield. China dominates scale, speed and execution, while the West still holds the keys to critical technological innovation and capital markets. The great irony is that this trade war of tariffs and blockades risks slowing down decarbonization at the most critical time for the planet. At the end of the day, the interdependence between both blocks is their greatest weakness, but also the only guarantee that, sooner or later, they are condemned to understand each other.

The cell phone on the nightstand is not “frying” your brain, but science is beginning to understand why it prevents you from resting

by

It is practically a ritual today: connect your phone to the charger, set the alarm and leave it on the nightstand just 30 centimeters from the pillow to sleep. According to the data, for 95% of adultssleeping with your phone within reach is a logistical necessity; For a growing stream of longevity experts, It’s a biological miscalculation. because we rest less. To do this, we have analyzed the bibliography to know exactly the effect of having your cell phone next to you. The culprit confirmed. Before entering the swampy terrain of the possible problems that radiation can generate when it is around us, we must point out the “elephant in the room.” The most solid evidence we have today does not blame antennas for having a bad sleep, but to the screens and what we do with them. To give us an idea, a meta-analysis over 36,000 participants concluded that excessive use of smartphone increases the risk of having poor quality sleep by 228%. The double responsible. The first is the suppression of melatonin, since the blue light emitted by the LED panels of mobile phones tricks our brain making him believe that it is still day. This delays the release of melatonin and fragments the architecture of sleep. But not only the blue light is information, since responding to a WhatsApp or doing doomscrolling on TikTok before bed keeps the brain alert. A study of medical students suggested that nighttime cell phone use corresponded to poorer sleep. The radiation debate. It has always been a mantra for many: having your cell phone nearby is having a large source of radiation that causes many health problems. In this case, organizations such as the WHO or ARPANSA have traditionally maintained that evidence of damage from low-level electromagnetic fields is “insufficient.” However, it does not mean that it is non-existent. The most recent studies They are beginning to see the non-thermal effects that mobile phones have. One of the most interesting was done with baby monitors that have a frequency of 2.45 GHz, similar to Bluetooth or Wifi, to simulate environmental exposure. The result was that the exposed group, compared to the placebo, showed a worse subjective quality of sleep and alterations in heart rate variability, suggesting that sensitive people do notice the invisible “presence” of the electronic device nearby. Brain wave modulation. Other research on 5G signals found that exposure to 3.6 GHz waves affected sleep spindles during N2 phasethat is, light sleep that accounts for 50% of the total rest time. The curious thing about this study is that the effect depended on genetics: only carriers of certain variants of the CACNA1C gene showed alterations in the electroencephalogram. This qualifies the warnings of some experts, since radiation may not affect us all equally, but for a genetically predisposed subgroup, sleeping next to a continuous emission source could be fragmenting their N2 phase, crucial for memory consolidation. The habit factor. It is often cited Sinha’s studio to demonize radiation, but what this study really measured were habits in a sample of 566 participants. In this case, it was seen that those people with high mobile phone use took longer to fall asleep, their sleep was less efficient, and 22.6% reported worse quality of sleep. In this way, the conclusion was not that the waves prevented them from sleeping, but that the habit of having their cell phone nearby inevitably leads to using. If it’s on the table, you look at it. If you look at it, you become active. It is a behavioral rather than a radiological vicious circle. Hygiene protocol. The question in this case is inevitable: should we wrap the room in aluminum foil? It’s not necessary. In this case, physics works in our favor thanks to the inverse square law: the intensity of the radiation falls drastically with distance. That is why the most important thing is to move the device at least one meter away from the bed, since at this distance the exposure falls to negligible basal levels, making Sleeping with your cell phone under your pillow is the worst possible decision. If we want to go a little further, we can put it in airplane mode, although the best advice, as the Spanish Society of Neurology points out, is to have a sacred hour, where the recommendation is to leave the screens an hour before going to sleep.

In recent years, much of the technological discourse has insisted on this idea, also driven by the arrival of assistants such as ChatGPT, Gemini or the different co-pilots integrated into everyday software: fewer routine tasks, more time to think, create or decide calmly. However, as these tools begin to be truly used in real environments, a question arises that can no longer be ignored: what happens when that promise of relief is confronted with the daily practice of work. Depletion system. The narrative of relief begins to crack when academic research looks at what happens inside companies. A study published by Harvard Business Review describes that, in the observed case, the AI ​​did not decrease work, but rather tended to intensify it, even without explicit orders to produce more. These findings can be interpreted as a sign of an emerging problem, where increased capacity can push certain organizations towards dynamics close to structural exhaustion, more linked to constant acceleration than to the promised efficiency. Where does the data come from?. The aforementioned work was developed for eight months within an American technology company with about 200 employees, combining in-person observation two days a week, monitoring of internal communication channels and more than 40 in-depth interviews with engineering, product, design, research and operations profiles. The company did not mandate the use of AI or set new performance goals, although it did offer enterprise subscriptions to business tools, which allowed it to analyze what happened when adoption arose on the initiative of workers. The pattern behind the promise. Far from a sudden change, the intensification described by the researchers takes the form of a recognizable process. The magazine summarizes its findings in three mechanisms that, combined, transform the daily work experience: progressive expansion of responsibilities, increasingly blurred boundaries between activity and rest, and simultaneous management of multiple tasks supported by AI. The increased activity began, in many cases, with something that at first glance seemed positive: the feeling of being able to do more on one’s own. It was no secret that AI makes it possible to tackle tasks that previously required external support or specific knowledge, gradually expanding the perimeter of its role. However, this growth did not replace previous responsibilities, but rather added to them and triggered new demands for supervision and adjustment within the teams. When the pause is no longer a pause. The study also shows that this dynamic not only arises from doing more things, but from doing them at different times. By reducing the initial effort required to begin a task, AI made it easier for work to slide into spaces traditionally reserved for rest, such as meals, short intervals, or the end of the day. Over time, this barely perceptible continuity transformed the work experience into something more constant and less delimited, decreasing resilience even without formally increasing hours. Fragmentation of care. Harvard Business Review points out that the possibility of executing several actions at the same time, relying on systems that work in the background, pushed many professionals to maintain an increasing number of tasks open simultaneously. This multiplication of fronts generated a feeling of momentum and support, but also required frequently reviewing the results produced by the AI ​​and continuously changing context. As this behavior became habitual, expectations of speed tended to rise within the organization. A possible way out. The study suggests that the problem does not lie in the technology itself, but in the absence of frameworks that regulate its daily use. Therefore, it proposes developing an “AI practice” based on intentional pauses that allow decisions to be reconsidered, work sequencing that reduces fragmentation, and moments of human connection that counteract isolation. In this scenario, the challenge for companies stops being to adopt more AI and becomes integrating its capacity without eroding the balance of daily work.

They have you in from the beginning

Betting houses sell a dream in their advertisements: anyone can win. The reality is just the opposite. They are designed to identify those who know what they are doing and neutralize them before they become a problem. A data journalist from The Economist he discovered it the hard way. After building models to detect miscalculated odds, Ladbrokes allowed him to bet exactly five pounds on the NBA MVP award. All other British houses closed their doors to him soon after. Not to make a lot of money, but to show that he knew what he was doing. The algorithm ranks you before your first bet Platforms don’t wait to see if you win or lose to evaluate you. They start much earlier. Do you enter from a computer or from your mobile? Do you deposit with a debit card or electronic wallets? Are you a woman in a sector where 90% are men? Each technical decision feeds a risk profile. An industry consultant explained it this way to The Economist: When you make your first bet, the houses already know with 80-90% certainty how much money they are going to win or lose with you. The initial play confirms or denies suspicions. A normal bettor bet on the Premier League or the NFL half an hour before the game, choosing the winner without comparing the odds too much. And he likes the combined ones: five, six, twelve crossed bets that are much more profitable (and therefore much more complicated to get right). a professional does the opposite. Bet on minor leagues as soon as the odds are published, when they still contain calculation errors. Look for derivative markets, such as how many points will be scored in the second quarter or whether a secondary player will beat a certain statistic, because that’s where the algorithms are least accurate. He never makes combinations. If your first bet captures a clearly mismatched market share, the restriction comes immediately. If not, the system needs less than ten moves to confirm it through the closing-line value: If you consistently bet better than the final odds, the algorithm already knows that you are a problem. Anthony Kaminskas runs ak Bets, a small house with 50,000 accounts. He perfectly remembers that British journalist’s first bet: 25 pounds on a basketball result that would take five months to resolve. Among hundreds of customers betting on the day’s football, that was too loud. He restricted it to 30% of the standard limit on the spot, adding a note: “This user has found a price where he has an advantage.” Whaling is more profitable than expelling ready whales But the system is not designed just to kick out the good guys. Its true function is to distinguish between three types of winners: Those who know. Those who are lucky. And those who are about to lose everything. They treat them depending on which group they belong to: “Those who know” are expelled. They keep the lucky ones close, waiting for their luck to change. AND The “whales” (players with a lot of money who bet badly) are pampered with VIP treatment: trips, five-star hotels, front-row tickets… Everything so that they feel entertained and continue betting happily, even if they tend to win. In 2023, DraftKings identified Felix Baum as a whale. They paid for a trip on the Indiana Pacers plane and a night at the Four Seasons. He turned out to be a camouflaged professional. But the cost of that mistake is pocket change: a year later, PointsBet raised its market share in New Jersey from 11% to 24% after catching a single real whale. The problem is that some professionals specialize in imitating whales: They purposely lose large sums on “silly” bets, such as accumulators in a very popular sport, so that the system raises the limits. When the house lets its guard down, they recover their losses and disappear with a net profit. The best ones even log on at three in the morning when there are games in other time zones, imitating the compulsive behavior of an addict. When all the doors close to you, the black market remains If all platforms restrict you, the options are a little murky: Houses in tax havens accept cryptocurrencies without asking questions, but then cancel winning bets citing “suspicious patterns.” Physical stores accept cash, but only in small amounts, and you have to constantly change hats and sunglasses to avoid facial recognition. The alternative is resort to front men. Family and friends who bet following your instructions. With the right precautions, such as never using the same WiFi or keeping each account on different devices, it is often almost impossible to detect. An attendee at BetBash, a professional betting conference in Las Vegas, explained that he has twenty different iPads and drives around his state so that each bet comes from different locations. Another recruits mules at his church. When the circle of trust is exhausted, there are professional intermediaries who sell access to networks of front men. They keep between 10% and 50% of the profits depending on the volume they move. Meta-fraud is included in the price: they estimate that between 3% and 5% of the mules will disappear with the money. Professionals do not want the system to change Several governments have attempted to ban these types of restrictions. The surprising thing is that professionals do not support these changes. If the houses could not limit accounts, they would worsen the odds for everyone or stop offering exploitable markets. “The restrictions are the best thing that ever happened to me,” says industry veteran Chris Dierkes. “They keep the competition away and make me money”. The entire system works because it benefits everyone who knows how to play: the houses maximize their profits by concentrating on the losers, and the professionals keep the market inefficient. And the casual bettor, convinced by advertising that he can win, keeps turning the crank. In Xataka | “Betting is … Read more
