We believed that the secret to rest was sleeping eight hours. A study has shown that we forget a big element

by

One of the mantras most repeated ad nauseum in the field of health is related to the need to sleep at least eight hours nightly. A goal that has been widely studied with the repercussions that failure to meet it may have. But now we have seen how the regularity in sleep is a much more powerful preacher of long-term health than mere duration. It’s when you sleep. Although we had very ‘glorified’ how much sleep we have to, trying to make up for lost hours on the weekendthe reality is that the important thing is to have good consistency, as is the case with many other processes. The regularity. The scientific consensus on this paradigm shift is gaining strength, and the last major proof is published by the National Sleep Foundation with an article that points to this regularity as one of the most forgotten components of our nocturnal habits. The key here lies in the internal clock, since we must remember that the time of waking up and early exposure to natural light is what activates our internal system with the cortisol release. In this way, by maintaining a constant reference, we ensure that critical biological processes, from hormonal secretion to body temperature, are regularized. When we don’t respect it. Just like when we travel to another country and we follow schedules very different from ours, the same thing happens here. We have the classic situation on the weekend, where we go to bed late and get up two or three hours later than usual, and surely the feeling when we get up is exhaustion. This is what is now known as ‘social jet lag’ or ‘Monday jet lag’, responsible for that mental fog, lack of alertness and low cognitive function with which we start the week. A shield. Unlike total sleep duration, regularity is a direct marker of the integrity of our circadian system, since when the internal clock and the demands of the environment become out of sync, known as chronodisruption, the body suffers. Just like when we travel between countries or experience time change. Here, a study published in Health Data Science HE dedicated analyzed more than 88,000 adults in the United Kingdom and found that irregular sleep patterns are associated with a greater predisposition to suffer from up to 172 different diseases. In fact, actigraphy studies have shown that intra-individual variability in our sleep hours is a direct marker of all-cause mortality, so trying to accumulate hours on Saturdays and Sundays not only does not save the furniture, but it puts us at risk. The impact of irregularity. In this sense, a linear relationship can be seen between sleep instability and the risk of suffering a cardiac event. But trying to “compensate” for tiredness on the weekend also results in worse insulin sensitivity and ends up altering glucose metabolism, which causes the bill to be quite expensive in the long run. Furthermore, the lack of a clear sleep routine causes a chronic pro-inflammatory state. This alteration compromises our immune response to pathogens, worsens the regulation of autoimmune diseases, and decreases the ability of our cells to repair themselves and eliminate metabolic waste. In summary, following set hours of sleep is essential if we really want to have optimal results in our daily lives.

The success of Artemis II has lit China’s space fire. Now, your space station will be twice as big

by

All powers have embarked on the new space race and Artemis II It has been the lighthouse that demonstrates the interest that continues to arouse in sending humans outside our borders. Aside from rockets, in low orbit humanity has one of the most exclusive laboratories in the universe: the International Space Station. While the long-standing facility awaits dismantling, China has just sent a message with its Tiangong space station. Soon, it will be twice as big. Ambition. When China was left out of the International Space Station project, it got to work on its own facility. The Tiangong It began to take shape in the 2000s and launched its central module into low orbit in 2021. Other modules have been added designed for Chinese astronauts to investigate in an environment that, until now, was forbidden to them. Since then, it has become a symbol of the ambition of the Chinese space program. Also of the speed at which they are completing goalswith round trip rocket tests and plans for build, together with Russia, a lunar station. Despite everything, he has a problem. It is considerably smaller than the ISS and has a mass of just 100 tons, a pressurized volume of 340 m3 with the capacity to house a crew of three astronauts. Expanding the Tiangong. The ISS can support a crew of seven astronauts, has triple the pressurized volume capacity and a mass of more than 420 tons. If China wants to get involved in space research, it had to do something, and its response has come in the form of a project to expand the Tiangong. How has informed state television CCTV, the station will go from being a ‘T’-shaped structure with three modules to a cross-shaped one with six modules. Its mass will be approximately 180 tons and, although it will remain smaller than the ISS, it will have the capacity to equal the astronauts on a permanent mission: six. If the plans are fulfilled, the three current modules will be joined by a fourth that will have multiple docking ports that will give rise to future laboratory units, increasing the potential to six modules. At the moment, there is no date for this expansion, but it is estimated that work will begin around 2027 and will be a Long March 5B the rocket that will transport what is necessary. Since its T-shaped module was completed, astronauts have performed more than 260 experiments and 26 spacewalks. Exclusiveness. China spent 2025 launching rockets, culminating in a month of December in which they broke all their launch records in a stress test for your multiple mission points. With plans to expand their space station, they show that they are committed to this new era of research and exploration, being something that arrives just when the International Space Station remains in question. Tiangong has remained an exclusive laboratory for Chinese researchers, but if it suddenly becomes the only station in low orbit, China is the one that has the access key so that foreign astronauts can carry out their work in those special conditions. On April 22, the Chinese Manned Space Flight Agency already commented that two Pakistan Air Force pilots would be trained as reserve astronauts and one would travel to Tiangong. He will be the first non-Chinese astronaut to do so, although there are already other astronauts from Hong Kong and Macau who will perform the same process. It is something that responds to China’s intention to promote cooperation projects with the United Nations Office for Outer Space Affairs, but without forgetting that the Tiangong is Chinese and, as we say, they have the keys to the doors… and the right of admission. Scrap. While the Asian giant announces the good news around its station, on the other side of the world a dismantling process of the ISS is still scheduled for 2031. The plan is that NASA use a vehicle exclusive to SpaceX to guide the ISS to a space cemetery somewhere in the Pacific. In recent months there has been a lot of discussion about whether it is a better idea to dismantle it, turn it into scrap metal or use it as a portbut at this point, the plan continues its course and it is possible that, sooner rather than later, Tiangong will remain the only manned space station in low Earth orbit.

cost savings are becoming very expensive for big tech

by

Large technology companies have been in a dynamic for months that is difficult to understand if the current technological context is not taken into account. Companies that, according to your tax results of the first quarter of 2026, record historic profits close to 80%they are cutting jobs at the same time. What is happening in their workforce has nothing to do with a financial crisis, but rather responds to a strategic decision regarding AI. According to the records from the portal Layoffs.fyiSo far in 2026, more than 92,000 employees in the technology sector they have lost their job throughout the world due to layoff rounds that the main technology companies have launched. The main argument for these layoffs is AIbut not because this technology is going to do the work that programmers used to do, but rather it responds to a restructuring of companies to lighten their workforce and focus only on developing AI. The measure is not coming cheap. The big bet of AI that must be paid. By chance (and the proximity to the presentation of their first quarter results) Microsoft and Meta announced, on the same day, layoffs that will affect more than 16,000 employees between the two. Meta will lay off 8,000 workers, 10% of its global workforce, and will leave another 6,000 vacancies unfilled. The goal of both companies is to improve efficiency and offset investment in artificial intelligence. Microsoft will face investments close to 145 billion dollars only in this fiscal year, thus adding to investments in AI what are they doing each and every one of the big technology companies. Maintaining that bet without margins suffering forces cuts, and personnel is the expense that investors like it less. Altogether, investments worth 700,000 million will be accumulated among all large technology companies during 2026. These estimates also include compensation expenses that are associated with these personnel cuts. Oracle, for example, reserved 2.1 billion dollars only for this game in your round of 30,000 layoffs. Microsoft launches a different formula: voluntary dismissal. Instead of announcing collective layoffs, Microsoft has chosen a path that the company had never used in its 51-year history: making voluntary exit offers to encourage its employees to leave by their own decision. Google already applied this formula of voluntary dismissals in its 2025 personnel cuts, not without the risk of losing its best employees by opening the exit door for them. This initiative is aimed at employees with a very specific profile who, in theory, would be more complicated to relocate to a new internal position within the framework of this workforce restructuring. In total, this offer has been made to 7% of its workforce in the US, more than 8,500 people. Amy Coleman, Microsoft’s chief people officer, announced the move in an internal memo. In that statement to which had access CNBCColeman wrote: “Our hope is that this program gives those eligible the option to take that next step on their own terms, with the company’s generous support.” Why an incentive instead of a layoff. Both voluntary departure and conventional dismissal have the same outcome: the workforce is reduced. However, as as highlighted to Fortune Domenique Camacho Moran, lawyer and partner at the Farrell Fritz law firm, specialized in labor law for Fortune 500 companies, traditional layoffs are legally more complex because they require evaluating the performance of each worker and argue his dismissal to avoid legal risks. “The voluntary exit option gives the employer the ability to say that it’s not that we don’t think you’re doing a good job, but that if you’re thinking it’s time to move on, I’m going to encourage you to do so because we need to downsize.” Incidentally, since it is an initiative of the employee, the company does not have to look for arguments for dismissal, which simplifies the process and avoids future legal claims. A risky bet for talent. However, as we already mentioned, the voluntary dismissal formula is risky since it leaves the decision in the hands of the employee. possibility of resigning. In a context of shortage of specialized talent (especially in AI), companies run the risk that their best swords will accept the incentive, paying a double cost for it. Last year, Google offered voluntary departures across several teams, including its search and advertising division. Vice President Nick Fox was blunt in his memo: “I want to be very clear: If you are excited about your job, energized by the opportunity ahead of you, and performing well, I really (really!) hope you don’t take it.” as collected CNBC.

why the silent user is the big winner of social networks

by

A few years ago social networks were used as authentic repositories of information, with many publications throughout the day and maximum interaction. Nowadays it is not unusual to see Instagram profiles completely empty of posts and reserved only for stories or even on X people who publish absolutely nothing, but have a really old account. And it’s not that they are dead accounts, but that their owners are just “watching”. A paradigm shift. The technology industry has been selling us the need to have a presence on social networks to participate in the collective trend and with the aim of staying behind. But for science, these people who just watch without participating are actually the most intelligent and have received the name ‘lurking’. For a long time, this attitude was attributed to a lack of commitment, but the reality is that lukers We represent the vast majority of users on the Internet, who only prefer silent consumption without entering into controversies or commenting on anything at all. In this way, our opinions remain in our minds and are not materialized by putting an answer on X or a comment on YouTube on a video. Why does it happen? Here a key study from Frontier in Psychology has analyzed the psychological mechanisms behind this technological retreat and points to four critical factors: Seeing the lives of others generates pressure that inhibits the desire we may have to share our own life or our concerns. Concern for privacy, since a publication can easily be misinterpreted without context and expose itself to unnecessary controversy. The pressure to generate social interaction in the comment box of different platforms is something that can deplete our energy reserves. There is an excess of interactive stimuli that causes the brain to not be able to process more. Consumption without exposure. Not all those who remain silent do so for fear of entering into a controversy, but for many, it is a matter of efficiency. Here, according to a job from Computers in Human Behavior, the motivations for consuming content such as watching a tutorial on YouTube or reading a thread on X are totally different from those for participating. Here the user seeks mere usefulness for their daily life, making reading comments help to contextualize a news item without having to enter the mire of discussion. In this way, the user feels that they are up to date with all the news that may surround them, but without having to type a single word. The dark side. The problem is that these attitudes indicate that the level of toxicity on social networks is quite high, which is why this ‘defense mechanism’ is activated in which a user does not leave because they do not want to lose connection with the world, but they ‘turn off’ their microphone. In the end it is a selective withdrawal in which you continue to see what is happening, but the noise is not allowed to directly affect the user.

Big Tech is pouring billions of dollars into GPUs for AI. 95% are inactive

by

When the COVID-19 pandemic began, toilet paper and yeast They flew from the supermarket. Paper because it is a basic good, but yeast because everyone was going to make a lot of bread in his house. That was the forecast, but we would really have to see how many of us ended up making bread. Well, something similar is happening in the data centers at the moment. Hyperscalers have spent billions and billions of dollars on GPUs for AI and, according to one report, 95% are idle most of the time. And all because of the fear of being left out. Kubernetes. Before getting into the matter, there is a concept that must be landed on. It is the one of the kubernetes. It is a kind of “operating system” in data centers, the foreman who organizes and monitors all the software that is being used. Imagine that a data center is a supermarket, the shelves are the servers and the products are the apps. Example of a control panel What this foreman does is find the perfect shelf to place the product in the most optimal way possible. In addition, he is constantly monitoring all the shelves at all times with the aim of not missing anything and ensuring that the data flow is perfect. It is, in short, a software that manages many physical servers in a very optimized way and 24/7. What’s happening. That said, the 2026 State of Kubernetes Optimization Report prepared by Cast AI has just revealed something: the tremendous inefficiency of data centers. They have analyzed about 23,000 kubernetes clusters in giants such as AWS (Amazon), Azure (Microsoft) and GCP (Google) and have discovered that the average GPU utilization of these data centers is just 5%. This translates another way: 95% are inactive most of the time, which implies that these companies are paying to get 20 times more computing capacity than they really need. Right now you might be wondering if it was worth it. destroy the RAM and SSD marketmaking computers, mobile phones, consoles and practically everything more expensive. And it is a question that makes all the sense in the world, but there is another interesting fact. To worse. As we see in TechRadarthose responsible for Cast AI point out that it is “the third year that we published this report and the numbers are getting worse.” Specifically, we are talking about CPU usage falling from 10% last year to 8% currently, while memory usage fell from 23% to 20%. Oversized needs. Something that the report also points out is that, although the use of equipment drops compared to the previous year, hyperscalers continue buying as if the world was going to end. CPU overprovisioning, as they describe it, increased from 40% to 69%. In the case of memory, it went to 79%. FOMO. A few weeks ago, one of the leaders of SMIC, the large foundry in China, already pointed out that Big Tech was buying all the resources that they will need, or that they think they will need, during the next decade… but in just a couple of years. They are investing a fortune in creating wide highways when there are no cars or real demand, and from Cast AI they are pointing in that same direction. Hyperscalers are buying piecemeal due to fear of being left out. It is what is known as FOMO or fear of missing outsomething that applies to many scenarios, but here it has to do with not wanting to come last in the race that is moving many millions from one place to another. This hoarding instinct is fueling a cycle of component shortages that affects consumers, but also the industry itself. According to the report, it makes some sense to want to buy everything as soon as possible because delivery times are long, but they are precisely so because everyone is buying more capacity than they need. Math doesn’t work. In the analysis they also point out that there are clusters that do not have such bad performance and that there are some that are using 49% of their H200 or 30% of their H100, well above the aforementioned 5%, but it is not the norm. And beyond having exploded the components market, the consequence of having so much equipment idle is that they are losing money because they are not profitable. According to calculations, an unused CPU costs a few cents per hour, but an idle GPU costs several dollars. And therein lies another key to this whole matter. Amazon or Azure data centers serve to satisfy the demands of their own companies, but they also rent computing power to whoever needs it. And since having the GPUs stopped costs them money, in recent months it has been reported that the prices of those rentals are multiplying. When will it all end? Cast AI is not optimistic, since they claim that most hyperscalers prefer to assume the costs rather than change their habits for fear that this will take off one day and catch them on the wrong foot. The translation is that… I will never have my Steam Machinesince everyone is focused on making hardware for AI.

In silence, the US is arming Spain’s most uncomfortable neighbor on the other side of the Strait of Gibraltar in a big way.

by

The scene took place in the 1980s, when the United States discreetly used bases in southern Spain to launch air strikes on Libya, an operation that showed to what extent the strategic balances in the Mediterranean could depend on little visible agreements for public opinion. Decades later, that same board moves again, although along less obvious paths for Spain. A silent turn in the Strait. In the surroundings of Strait of Gibraltar A fundamental strategic change is taking place that does not respond to a single movement in itself, but to an entire accumulation of decisions sustained over time that are strengthening Morocco. as a key military actor on the southern European flank. This movement, although it is still not public, has now acquired character official with the signature of a road map of defense between the governments of Rabat and Washington for the next decade, a movement that is neither trivial nor an isolated gesture, but the formalization of a broader commitment in which the United States consolidates Morocco in the next 10 years as itsyour preferred partner in North Africa, with direct implications for regional balance and, no doubt, for Spain’s position. From regional partner to strategic platform. Yes, because the relationship between both countries has evolved to make Morocco more than an allygoing on to play the role of operational and technological platform from which the United States projects influence towards Africa and the Mediterranean. There are several examples, for example, the exercises as African Lionwhich integrate troops, industry and technology, and reflect this transformation, as well as the incorporation advanced capabilities as the Link-16 systemwhich brings Morocco closer to NATO standards. This leap not only improves military interoperability, but also places the country in a privileged position within the Western security architecture. Access to advanced technology. The reinforcement of this alliance translates into a military modernization unprecedented, with a significant increase in defense spending and access to systems that until recently were out of reach, from helicopters Apache attack up to guided munitions and potentially the almighty F-35 Lightning II fighters. Added to this is the development of a self defense industrywith production, maintenance and training plants that allow Morocco not only to acquire capabilities, but to begin to consolidate them autonomously, reducing its external dependence in the long term. A rearmament to change the balance. Be that as it may, and despite this progress, Spain maintains a clear superiority for now in structural termsespecially in the naval field and in its technological and industrial base, which allows it to retain a significant advantage over Morocco. However, this advantage is no longer as large as in the past, and the trend and agreement with Washington aims for a progressive convergence, driven by Moroccan economic growth and its sustained investment in military capabilities. If you like, the result is not an immediate balance, but an increasingly competitive environment in which the distance between both countries is reduced constantly. Technology, influence and projection. Plus: Morocco’s objective is not limited to improving its military capacity, but is very possibly part of a broader strategy to increase its geopolitical weight in the Maghreb, the Sahel and the entire western Mediterranean. American support, along with its approach to other partners like Israelreinforces this idea and ambition, allowing Rabat to position itself as a central actor in regional security and as a privileged interlocutor of the great powers in the area. Gradual change. In short, the panorama that draw ten years view is not that of an abrupt and total break, of course, but rather that of a progressive transformation in which Morocco gains capabilities, influence and room for maneuver thanks to the US support. In this process, Spain will continue to be the dominant actor on the military level, but it no longer operates in a static environment, but in one in which its neighbor to the south, often uncomfortable depending on the circumstances, is getting stronger constantly, slowly altering the balance in one of the most sensitive points of Europe, and nuclear from Spain.

We believed that tons of feces were the big problem with the touristification of Everest. Until the scam rescue arrived

by

Everest may be the roof of the world, but it has long ceased to be the remote and isolated place they found themselves seven decades ago. Edmund Hollary and Tenzing Norgaythe first to summit its icy summit. The best proof was left to us just before the pandemic by Nirmal Purja, the author of one of the most famous (and striking) snapshots of the mountain: in it we see a very long row with dozens and dozens of tourists climbing in single file towards the summit, just as if they were queuing to enter the Louvre or board a cruise ship. That Everest has become a monster touristified It’s no surprise. What is curious is that there are people (presumably) breaking the laws to take advantage of that demand and defraud the insurers. A huge theme park. One would expect the highest place on the planet to be an inhospitable place, reserved for the most intrepid locals and adventurers. Perhaps it was like this in the 1950s, when Hollary and Norgay ascended to more than 8,800 meters of altitude to reach its summit. Not today. The photography that Purja took in 2019 is just the graphic verification of a phenomenon that can be measured in figures… and even in feces: Everest is a tourist icon that they visit every year hundreds and hundreds of climbers, leaving behind millions of dollars and a trail of tons of waste. You will find more infographics at Statista Where there is tourism… There is business, of course. That universal truth is applicable both in Amsterdam, Florence either Barcelona such as in the remote Himalayas, which over the last few decades has seen a thriving industry take shape dedicated to serving those who visit Everest. According to the World Travel and Tourism Council (WTC), in 2023 alone Nepal’s tourism sector generated revenue worth about 2.5 billion of dollars and boosted hundreds of thousands of jobs, both direct and indirect. Even Nepal has considered shoot 40% the fees he charges mountaineers, a source of income that among other things helps him clean the region. Where is the problem? Beyond the environmental impact that this overcrowding has in the mountain range, there is actually no problem in travel agencies, Sherpas, transportation companies, hotels and other businesses oriented to Nepalese tourism trying to make money. Climbing Everest doesn’t come cheap, but at the end of the day, whoever wants to pay for it. The problem is that not all of these professionals respect the law when looking for ways to make money. What’s more, there are those who have no qualms about cheatfalsify and commit millionaire frauds. Mountaineering and picaresque. The news I advanced it a few days ago The Kathmandu Postone of the largest English-language newspapers in Nepal. The Central Investigation Bureau of the Nepalese Police (CIB) has revealed a network dedicated to deceiving insurers who cover mountaineers in the Himalayas. Their modus operandi may vary, but the idea is always the same: alleged scammers make fraudulent ransoms to claim compensation. It may sound rudimentary, but the scam takes advantage of two circumstances that work in its favor. First, in rescue operations speed prevails, so there is no room to wait for the approval of the experts. Second, deceived insurers are often based thousands of kilometers away (in London or Paris), making it difficult for them to confirm what is happening on the ground. One goal, two methods. How do you prepare the scam? The CIB has identified two methods. The first is quite simple and requires the tourist to participate in the deception. If a climber is exhausted after days (or even weeks) of hiking and wants to save the trip back to camp, his guide can offer him a way out that is as comfortable as it is ethically questionable: faking an illness so that the insurance company can mobilize a rescue operation. The second method is a little more complicated, but the end result is the same. The guides or accommodations take advantage of the client’s ignorance to make them believe that the symptoms of altitude sickness (which are usually resolved with rest, hydration and a gradual descent) are actually signs that they are at serious risk, even of death. The key is to suggest the hiker enough so that he ends up asking to be evacuated by a charter helicopter. And where is the business? In the cost of the operation. It is not just that the company that provides that service charges the insurer for a helicopter that was not really necessary, it is that, precise The Kathmandu Postoften manages to expand its profit margin. As? It carries several passengers on the same flight and then sends separate invoices to their insurance companies. In practice that means that a single $4,000 charter flight can end up giving rise to three separate claims worth $12,000. Added to this are alleged treatments in the hospital, even when the client in question did not need assistance. For example, the Nepalese newspaper talks about cases in which treatment is claimed for hikers who were actually in the cafeteria. Not all people who are involved in this mess have to participate in the deception. He post speaks of falsifications of flight manifests or reports with digital signatures of completely unrelated doctors. One figure: 20 million dollars. At the end of March the CIB accused 32 people for this type of crimes, which according to the AFP agency amounted to a total scam 19.69 million of dollars. It may seem like a lot, but the figures revealed by the CIB investigation are eloquent: between 2022 and 2025, it identified 4,782 foreign patients treated in the investigated hospitals. Of these, inspectors believe that 171 corresponded to simulated evacuations. During that period some health centers received deposits worth millions of dollars related to those services. The older ones are the helicopters. Poisoning? The CIB investigation has attracted the attention of the media everyonealthough their headlines often focus on another … Read more

Now their big techs are looking for talent at the institute

by

China is quietly redefining who counts as tech talent. Some of its large companies in the sector have begun to skip university and recruit directly from institutes in a movement that indicates that creativity and learning ability are worth more than degrees. What until now seemed anecdotal is beginning to consolidate as a widely accepted deliberate strategy in search of talent. what’s happening. Beyond specific cases such as the signing of Chen Guangyu, a 17-year-old student from the Shenzhen technology hub, as an intern for Moonshot AI and who already signs first-level technical reportsthe trend is better understood with some examples: Huawei Genius Youth. Since 2019, the company has had a recruitment program looking for young geniuses. The Shanghai talent incubator by Zhang Yiming, founder of ByteDance: their goal is to hire 30 reserve researchers between 16 and 18 years old each year to train them in computer science and AI. Geely has an internship program for senior high school students with direct mentoring from their executives. Tencent has been running its Spark Program since 2019, an annual program to select students with high potential for internships in the company. The technology company also has an exclusive summer program for only 10 middle and high school students, such as pick up Sitx Tone. Why is it important. For decades, technological recruitment has operated on two axes: companies signed up for universities and the sector’s imagination celebrated the genius who left them. That companies as large as Tencent, Huawei, ByteDance or Geely skip both steps and go directly to the institutes is no coincidence: it is a sign that the speed of change in AI is making traditional training obsolete. If the talent that companies need is not in higher education when they need it, the market looks for where to find it. And he’s finding it sooner. Context. China has been stepping on the accelerator for decades in training: It is a world pool of engineers and is diversifying towards FP. It is true that behind this reality there are State plans that, without going any further, are currently erasing arts careers in favor of other strategic ones such as those related to AI. The icing on the cake is the perception of Chinese universities and their tendency towards memorization to the detriment of critical thinking and creativity, a criticism that has been documented for decades, as wield this Harvard report. And one layer below, there is need: the Asian giant’s race for technological talent is exacerbated by Western restrictions on the most advanced critical technology. In this scenario, self-sufficiency is an absolute priority, whether technological or human capital. The justification of the sector. Sixth Tone picked up the statements of Li Shufu, president of Geely, at the presentation event of its internship program: “In the era of AI there is a gap between the talent that companies need and what universities currently offer.” It also provides the statements of a human resources person from an artificial intelligence company who speaks directly about creativity. Those younger people who do not yet have fixed mental schemas can imagine different solutions and products, outside the academic canon, which in some contexts can be a competitive advantage. Crossing borders. The questioning of the university degree as a talent filter is a global phenomenon that is beginning to cross borders. One of the most aggressive companies in implementing it is the American Palantir, which last year recruited to 22 people who had recently graduated from high-level secondary school (they were aiming for the top universities) for paid internships with the possibility of direct hiring. It’s your “anti-scholarship”. Sergey Brin too has declared that Google hires a lot of people without a degree and that they are able to get by in a peculiar way. The signals are converging: the recruiting model from Shenzhen to Silicon Valley points to a shift in the most advanced segments, prioritizing ability over titles.

We have been sending pregnant women to bed for decades as a precaution. Science has just proven that it is a big mistake

by

In the face of a potentially risky pregnancy, the prescription that was administered was very clear: absolute bed rest to avoid any fall or inappropriate movement that could cause an abortion. But this is something that today is no longer the norm, since staying still during pregnancy not only does not prevent the premature birth of a baby, but it can be very harmful. You have to move. Here, institutions as important as the Mayo Clinic are quite blunt in their guidelines by noting that there is no evidence that bed rest is effective in treating preterm labor. To reach this conclusion, they logically resort to different clinical studies inside the Cochrane Library In this case, they point out, for example, that in singleton pregnancies, routine bed rest does not prevent premature births and, in fact, the adverse effects of being immobilized outweigh the supposed benefits. In the situation of being in a multiple pregnancy, hospitalization and strict rest do not reduce perinatal risks and, ironically, an increased risk of spontaneous birth has been observed. What dangers does it have? Lying in bed may be something that a priori is seen as completely harmless, but the reality is that science advises against it for different reasons. The first of them is that immobility increases the risk of venous thromboembolism if one is not properly anticoagulated. In addition, it causes bone demineralization, where an estimated loss of bone mass is 2% to 3% per month, muscle atrophy and weakness, orthostatic hypotension, and is also associated with low neonatal birth weight and a higher rate of cesarean sections. Beyond the physical. Having complete rest isolates the pregnant woman in a bed watching television all day, and this only causes increased emotional stress, anxiety, and can lead to depression. In studies, this is something that currently affects 20% of pregnant women subjected to this isolation in countries like the United States. What is recommended. The objective of the different international guidelines to treat these pregnant women has taken a great turn in recent years. The SEGO guide of Spain, for example, recommends these women with aerobic activity for 3-5 days a week, avoiding routine rest. If we cross the ocean, in the United States it is recommended 150 minutes of moderate exercise a week, also to reduce the rate of cesarean sections and gestational diabetes. There are exceptions. Generalizations are never good, and that is why you cannot ask all pregnant women for absolute rest, but neither for a lot of activity. Here the most current guidelines establish that there are very specific and documented cases, such as premature rupture of membranes, where this rest is necessary. But these cases are very few. What we must stay with here is that immobility during pregnancy is not the best, and we must stay active as much as possible with activities logically adapted to the pregnancy situation.

This planet is too big for its star. When we tried to find out the reason, we found something even more disconcerting.

The universe is so immense that it should not surprise us that it is full of exceptions. But even so, there is still such disconcerting findings that obsess astronomers. This is, for example, the case of TOI-5205 b, an exoplanet that attracts attention due to its size, too large for its star. That alone would be truly exceptional, but a new study has found that, if that were not enough, it also has a very unusual atmosphere. Too big for a red dwarf. TOI-5205 b is a gas giant, slightly larger than Jupiter. But only a little. While Jupiter orbits the Sun, this exoplanet orbits a red dwarf. That is, a relatively cold and very small star, with a mass ranging from 7.5% to 50% of the mass of our Sun. Typically, stars are MUCH larger than the planets that orbit them. However, the radius of this red dwarf is only four times that of TOI-5205 b. To continue with the comparisons, our Sun has a radius approximately 10 times larger than that of Jupiter. And it’s not just a radio issue. The mass of this exoplanet is also striking, as it is equivalent to 0.3% of the mass of the red dwarf. Jupiter’s mass is approximately 0.095% of the Sun’s mass. All this tells us that TOI-5205 b is too big for its star. An even more disconcerting clue. Recently, a team of scientists from NASA and the Carnegie Science Institute decided to study the composition of the atmosphere of TOI-5205 blooking for clues about its origin that explain why it is so big. However, what they discovered was even more disconcerting. They carried out the analysis of the atmosphere studying the transit of the planet. That is, analyzing the changes in the light of its star when the planet passes in front of it. When light interacts with the planet’s atmosphere, it interacts with the molecules found in it. Each element reflects light in different bands of the electromagnetic spectrum, so, with the help of a spectrograph, you can know which elements the light has interacted with and, consequently, what the composition of the atmosphere is. Astronomical metals. For astronomers, any element other than hydrogen or helium is considered a metal. Just for them, chemists don’t like this. The point is that this decision the concept of metallicity arises. It refers to the proportion of metals that a planet or star has in its atmosphere. When a star forms, it is assumed to take most of the hydrogen and helium present in the stellar nursery with it. Therefore, when a planet later forms around it, it is normal for its atmosphere to have a higher proportion of metals. For this reason, it is said that the metallicity of the planets is higher than that of their stars. But with TOI-5205 b that does not happen. According to analyzes of its transit, its metallicity is lower than that of the red dwarf. hidden metals. To verify what this phenomenon is due to, the authors of the study that was recently published carried out a series of mathematical models. With them, they wanted to check how the atmosphere of this exoplanet could have evolved under different scenarios. This allowed them to verify that the current situation is consistent with their metals having been buried inside the planet. It is true that when it was formed absorbed a greater amount of metals, since the star had taken more helium and hydrogen. However, these metals did not remain in the atmosphere, but were they saved inside TOI-5205 b. In the atmosphere, however, there is some helium and hydrogen, but also other compounds, such as methane and hydrogen sulfide. What this exception teaches us. As explained in a statement One of the authors of the study, Anjali Piette, “these findings have implications for our understanding of the process of giant planet formation that occurs early in the life of a star.” Sometimes, it is the exception to the rule the one that can provide us with the most data. There’s nothing like thinking outside the box. Image | Katherine Cain (Carnegie Science) In Xataka | Since we were children we have been told that Jupiter is enormous, colossal, exaggeratedly large. It is 8 km smaller and that changes everything
