diurnal solar surpluses, night spikes … and increasingly cheaper batteries

For years, conversation about the future of Spanish electricity has been reduced to fear of two words: “China photovoltaic”. Panels cheap and reasonably efficient. But the final weapon is not arriving in containers from Shanghai, but increasingly frequently in the van of a neighborhood installer: lithium batteries packs that allow reducing the dependence of the conventional electricity grid. Cut the cable. Or, at least, loosen it. The cheaper that changes the rules Past, present and future of the storage price: 2015: Storing a kilowatt-Hora cost more than 1,100 dollars/kWh. 2024: according to Bloombergnefthe average price of the pack was at 115 dollars/kWh (about 105 euros/kWh), after a 20% drop in the last year. 2026-2027: By then, the same consultant estimates that the psychological bar of the 100 dollars/kWh will be broken. With these prices, Storing domestic energy costs less than the term valley of the PVPC ratewhich now ranges between 0.11 and approximately 0.13 euros/kWh. That makes the battery the natural complement of any roof with panels and a direct enemy of the demand managed by the distributors. To understand the impact of this cheaper on the accounts of the companies in the sector, you have to understand how they earn money. Iberdrola. Its 2024 ebitda, According to its annual resultsit was almost 17,000 million euros, broken down like this: Networks: 6,423 million euros. 38% of the total. Generation and customers: 10,425 million euros. 62%. 52% of Iberdrola’s investment goes to networks, its most stable and regulated segment. Endesa. Its 2024 Ebitda reached 5,300 million euros, with a similar distribution: Electric distribution: 1,750 million (approximately 33%). The rest comes mainly from generation and marketing. Naturgy. With an Ebitda of 5,400 million in 2024: ELECTRIC NETWORKS AND GAS: They represent approximately 45% of the business. The company has increased its investment in this segment by 15% compared to the previous year. For all these companies, Each kilowatt-hora that does not circulate through its networks directly impacts its profitability. Today, the threat is hypothetical, but tomorrow it will be arithmetic. Battery and panel: the combo that takes off According to data from Auto: In 2021, only 2% of residential facilities included battery. In 2024 that figure reached 71%. And they are not just coastal chalets, hybrid kits reach peripheral single -family and even communities of pioneering neighbors. With subsidies and 2.0TD rateamortization drops between 6 and 8 years, and energy self -sufficiency touches 80% in optimal conditions. Electric grid as electron pipe begins to stagger. And not only because of the fall in the demand managed, but because the flow is reversed. In the moments of sun and low demand, thousands of homes are beginning to return energy to the network or simply not need it. For a company that invests billions in transport and distribution infrastructures, that is a problem. But the regulatory framework is starting to move. And your address is not clear. The CNMC has on the table The new toll methodology for the period 2026–2031. Among the Options in consultation: Move part of the fixed costs of the network at the end of power, and begin to remunerate flexibility services, such as storage or coordinated discharge of domestic batteries. They are two changes with opposite consequences: The first penalizes the self -consumer with drums, although he barely consumes. The second rewards it, if your battery helps to balance the network at critical moments. Everything will depend on how normative design is related. And who is heard more. But for now, the government Last the arrival of aid for energy storage through 700 million Feder funds. This transformation is not an isolated case. Several European and American electricity have understood the message before the Spanish. And they have begun to move. Nextera has already hired 81 GW from Solar With storage for 2027, with a good part behind the accountant. That is, in homes. Enel x He has launched virtual power plants pilots (VPPS) In Italy and agreements to display regulated batteries. EDF He is exploring flexibility markets in the United Kingdom and France. In Spain, Endesa has timidly begun to explore this land with its project FlexiCy In Malaga. The background logic is clear: The network will remain necessary, but less as a unidirectional route and more as a smart platform for exchange and balance. And the interesting thing It is not so much the exact point in which we are, but the slope of the curve. According to The International Energy Agencyto meet the objectives set in COP28, world storage capacity It must be multiplied by six before 2030. Of which 1,200 GW must come from batteries. Spain, with its diurnal solar surpluses and nocturnal peaks of consumption, is one of the most fertile land in Europe for that transition. Despite the fear of these years to the threat that came by boat – Chinese plates – the real threat is the one that arrives in a van. In lithium, phosphate and iron packages that allow each home to keep their own energy. In that context, The network business is focused on a transformation: to bill kilowatts to offer guarantees of energy continuity. And there is the key: whoever adapts to the new model will not only resist better. You can also lead it. In Xataka | We have second to second the data on the great blackout in Spain.

In favor and against an increasingly international and ‘desestationalized’ diet

Yesterday There were creeks in the supermarket. Round, orange and bittersweet, the fruits of the loquat of Japan are one of those little miracles that gives us May. And I know it is an anecdote: a handful of thousands of tons of an absurdly seasonal product distributed by the supermarkets of five or six Spanish provinces. But it made me smile, first; And frown, later. Because yesterday, looking at those two bars in the middle of the ocean of fruits and vegetables, I realize that we almost always eat the same. Yes, a varied and balanced diet: provided we do not get out of the same 20 or 30 fruit and vegetable references. There is a battle in the world of distribution forever, let’s eat the same; so that our diet is the most standardized the same; so that there are no media in the supermarket. It may seem exaggerated, but there are examples to thousands. If we think about it, the idea of ​​being able to go down to the store and find avocados whatever the time of the year is almost magical. Avocado flowering in Spain It occurs in April. Also in March and May, but especially in April. The collection and marketing, on the other hand, goes from October to March. What happens in the spring and summer months? Where do the avocados that fill the shelves of the supermarkets come from? The answer is that of Peru. Of other sites, but fundamentally from Peru. The market and globalization has achieved something incredibly difficult: to be able to have seasonal products throughout the year. Sometimes, bringing them from other areas of the world (as in the case of avocado); Other times, looking for macrovarities that allow their cultivation throughout the year. That is what happens with potatoes (extra -time, early, half -season and late) and tomatoes. The Jungle Law. In this sense, international trade and international coordination select products with the ability to generate sufficient demand to ensure its supply during the year is profitable. As not all products allow it, nor all consumer groups are large enough: the current result is that many traditional products can only be found at the local level and those of great consumption The shelves of the supermarkets fill half the world. In our pantry there is a fierce knife fight from which only the most suitable products for these plethoric market societies come out. Is such a standardized diet ‘a good idea? Without a doubt, it has positive things. For the love of God, we can eat avocados at any month of the yearHow are you not going to have positive things? For thousands of years humanity has had to eat what it touched, but now we are very close to simply eat what we feel like. And that, even in a subject so crossed by cultural, social and personal factors Like food, it limits the future of gastronomy: it unifies it little by little, it makes it less diverse and more insecure. But, without a doubt, more appealing: a breakfast buffet in a hotel of many stars: the best – the most popular – of each kitchen in the world. While science fiction writers imagined a future with astronaut food, A kind of Soylent with steroids. What we are discovering is that the diet is changing, yes; But towards the promise that in the end We will all eat more or less the same.

We are increasingly clear that our microbiome is key to our health. Our protein sources can also alter it

Little by little We started realizing Of the importance of our microbiota, especially as regards the microorganisms that inhabit our digestive system, our gastrointestinal microbioma. Aspects of our health that in principle They would not seem connected To what happens in our intestines seem to have some kind of correlation with that flora of fungi and bacteria that coexists inside us. Different proteins, different microbiome. A recent study has observed That the food source of protein can alter the composition and structure of our intestinal microbiome, that is, of the set of microorganisms that inhabits our digestive system. The experiment, conducted with mice, observed important variations in the microbiota associated with changes in the diet. “The composition of gastric microbiome changed significantly every time we change the protein source,” pointed in a press release Alfredo Blakeley-Ruiz, co-author of the study. “Protein sources with the greatest functional effects were integral rice, yeast and egg whites.” A variety of sources. Proteins are a key nutrient that gives us essential amino acids with which our body is able to synthesize its own proteins. Foods of animal origin such as meats, fish or eggs are usually seen as the main source of amino acids, but they are not the only one. The existence of alternatives implies the possibility of diverse effects on our health and well -being. Through, for example, of the microbiome. Metabolizing amino acids. The team resorted to its study to the use of high -resolution mass spectrometry and the combination of metagenomic and metaproteinomic. Everything to find how the intestinal microbiome of mice whose diet was altered so that each week they received their single source proteins that was changed after seven days .. They observed that some of these sources were associated with important changes. These changes, Explain the teamthey manifested in how the mice metabolized the amino acids, but also in the way in which their digestive system degraded complex sugars, something that was not so intuitive. Diets such as those based on the integral rice and the clearing of the eggs, continue to explain the equipment, increased the degradation of the amino acids, which would imply that the microorganisms of the digestive system of the mice were breaking the proteins to obtain their own amino acids. The details of the study were published recently In an article in The Isme Journal. An environment (too much?) Controlled. The team responsible for the study admitted That there are some limitations to consider, and one of them is the complexity of the diet. In a laboratory environment, the team altered the diet of the mice radically (causing them to have a single source of protein). Beyond the fact that studies with animal models are not always transposed identically in humans, it is expected that forceful changes in the diet of these animals entail important changes in the structure of their microbiome. A more varied diet, with diverse sources of proteins, would logically imply more dim effects.

Male routines are increasingly rare

They are almost four in the morning. While most are still asleep, there are those who believe that is the perfect time to begin to conquer success. It is not just waking up early, it is to follow a millimeter routine that mixes extreme discipline, self -care and sport. A man has taken him to the limit, and his video has gone viral. The new sensation. On X/Twitter, the @Tipsforenx account has published a Reel which has become a viral sensation on that network. However, the Original video I accumulate in Tiktok more than 8 million like and has been displayed more than 99 million times. In it we can Ashton Halla influencer Fitness, carrying out an extreme morning routine where he gets up at 3:52 in the morning to start the day. The routine The clip shows Hall taking off the Mouth Tapingwashing his teeth and prowling before exercising on the balcony. Then decide to read (two minutes, because the whole video is marked by times), write or manifest (a usual practice in these routines) and watch some videos on the mobile. Then, fill a bowl with water with gas from the blue bottle that always carries. Once ready, immerse the face in that bowl, and then we dress to train. Finally, he returns home, where a banana is shower and eats, which restrges the peel by the face. It’s already 9:00 in the morning and, again, put the face in ice with ice And, later, he is seen preparing what appears to be a podcast while preparing breakfast. @ashtonhall forgicial Day 191 of The Morning Routine That Changed My Life 3:50 am to 9:30 am without Lives Late at night .. If you’re dealing with a Weak Mind, Bad Decions, Or Lack of Productivity Go To Sleep Early. 4:00 am – 8:00 am not’s calling or distracting your productivity .. they are located. 8:00 pm – 12:00 am is the opposite. Just Try 30 Days .. Send This to Your Partners. It’s time to do Better. ♬ Original Sound – Worthy Supps “Morning Skincare Routine”. The morning routines of self -care began to become very viral in Tiktok, especially among womenwho showed their morning with a Morning Sheds followed by A little one Vlog With your exercise routine and personal care. In fact, these practices, when not taken to the extreme, can be beneficial for both physical and mental health, according to He explained Andrew Huberman, neuroscientist from Stanford University. However, this phenomenon has gained popularity among men, who seek to project an organized, productive and successful life, aligned with the constant pressure of optimizing every minute, as we can see in the video of Ashton Hall. In other words, the desire to maximize personal performance, but also a pressure on the physical and image. The cult of the body. The male aesthetic pressure and the obsession with appearance have been driven by the phenomenon of the looksmaxxingwhich implies the effort to achieve a “perfect look” through rigorous physical training routines, aesthetic surgery and personal care. As has detailed in Newtralthis type of culture reflects an obsession to maximize personal attractiveness, which leads many to invest in their image as a way of obtaining social and economic validation. In Xataka We have analyzed How this movement is not only related to fitness, but also to extreme self -care, reflecting a desire to meet aesthetic ideals imposed by social networks To achieve the status of “alpha”. Self -care, accompanied by strict exercise routines and habits such as skin care or supplements, has become essential in this approach to success. Influencers and investors They make their image A reflection of its financial success, associating aesthetic perfection with personal and professional achievement, in a cycle promoted by constant productivity expectations and social validation. The viralization. Ashton Hall’s video has quickly gone viral, generating parodies and imitations. However, what it does show is a trend between influencers, entrepreneurs and cryptoinversors promoting habits to “achieve success.” What was previously typical of elite athletes or military forces, has now transformed into an aspirational standard Within certain male circles. Beyond exaggeration and parody, this trend is pending among many men, establishing a new self -care code. In this new type of care, it coexists to hydrate the skin, meditate or make flexions at 4:00 in the morning in the same routine. In short, although in many cases these practices are adopted by social pressure or by obsession with productivity, they are gradually redefining the meaning of male self -care, with implications that deserve a deep reflection.

There are alarmed people because fruits are increasingly sweet. It is a more complicated phenomenon than it appears

A few years ago, Melbourne Zoo decided that he would stop giving fruits to some of his animals “because they were too sweet for their own good“In recent years, red pandas and primates had gained weight and some even had signs of decay. The reason tells a greater story about our relationship with the fruit. Too much sugar. “The problem is that cultivated fruits have been genetically modified to have a sugar content much greater than its natural ancestral fruits,” Michael Lynch explainedVeterinarian Chief of the Zoo, to the Sydney Morning Herald. It seemed a curiosity without much route, but it wasn’t. The idea that “fruit is not healthy because it has much higher sugar levels than in the old days” It has been circulating for years Online. In fact, come back again and again … But is it? The answer is complicated. If we go to the data (for example, to Central fooddataa database of nutritional analysis of food in the US), we can find some fruits in which that is seen growth. For example, “wild blueberries” would have 6.46% of sugars, while commercial “blueberries” would be at 9.96%. Growth is considerable, yes. What happens is that this effect disappears when, instead of comparing with primitive varieties, we analyze whether the fruit has been raising its amounts of sugars in recent decades. Angela Dowden He reviewed the United Kingdom data since 1946 and found no significant differences in the sugar content of apples, white grapes or strawberries. Giovanni Stanchi. This makes sense. For years, human beings have gone improving Fruits and vegetables to the point that they don’t look at anything. Giovanni Stanchi was an Italian still life of the seventeenth century. At some point between 1645 and 1672, Stanchi painted a picture full of peaches, pears and watermelons. Watermelons that do not look anything like ours. And it’s not that it was anything new. The watermelon was a plant of Africa that for 1600 (via al-Andalus) It was already extremely popular in the orchards throughout Europe. Bodegons give us An unbeatable opportunity To see how the watermelon has changed until today. By 1860, the watermelons They were acquiring an appearance more recognizable. It is not just a matter of appearance. Also of flavor. We have seen it With tomatoes (Although, in this case, Often for worse) and we could see it with almost all fruits and vegetables. For example, Brussels cabbage They are much less bitter That 20 years ago. The point is that, when we talk about sugars in fruits, we will see that growth has a limit. A physical limit. In general, As the botanist James to Wong explainedfruity sugars levels tend to converge in a very similar range because, as with tomatoesplants can not manufacture more sugar without becoming much larger or produced less (and none of that interests us at a commercial level). But there is something else. Let’s go to nutritional data to see it clearly: following Dowden’s data, super sweet “modern” strawberries contain only 4.89% of sugars, while Kiwis have 8.99% and bananas have 12.23%. This gives us an interesting key. As Wong points out, what fitomejoradores do is that “the fruit has a sweeter flavor not increasing sugars, but reducing acid and bitter chemicals that mask their sweetness.” And there is the explanation of what happened with Melbourne’s animals. The problem was not so much the level of fruits sugars (which, Rememberbeing “fiber -packaged fructose” cannot increase blood sugar levels as refined sugars), but were so good that pandas and primates stopped eating other things and their diet was unbalanced. It does not seem a problem that affects us human beings. Hopefully the fruit would gain weight in our diet because that would mean that, on average, the feeding of society would improve. What we are seeing is, in fact, it is just the opposite: the weight in our processed food diet tripled between 1990 and 2010 (from 11% to 31.7%) and that led to the added sugars added will pass from 8.4% of our daily energy intake at 13%. Within our dietary concerns, the sweet fruit is not among the worst problems.

The audiences, in unpredictable terrain between the bad Broncano streak and the increasingly patent recovery of TV5

‘La Revuelta’ It seems to have worked as a revulsive for the stagnation situation that the traditional television audiences liveEl Hormiguero‘. Nothing that was released in that strip seemed to be able to compete, and no format that Tele5 experienced after the fall of ‘Save Me’ planted face. From the fall of last year, however, and with its audiences matching and surpassing those of motorcycles, Broncano seems to have launched a poisonous dart, a doubt: there is nothing sure in the figures of linear television spectators. Broncano collapse. A little less than a month ago We talked about how, with six months of the premiere of ‘La Revuelta’, the competition with ‘El Hormiguero’ had not yet thrown clear data. In the last quarter of 2025, Broncano came out victorious, however little, in the strip of strict coincidence and also in the number of spectators. However, both the Champions and, especially, the unexpected success of ‘The island of temptations’ has affected Broncano’s figures, which had a historical minimum last March 12 And, in general, its lowest figures since it premiered in autumn. The solution, this Thursday. Taking advantage of the fact that this Thursday will be issued number 100 of ‘La Revuelta’, TVE will experiment changing the emission timeand delaying it until 22.35 hours. Like so many other times, Broncano sees his time changed because of football, since TVE will give the match between Spain and the Netherlands before. The seventh gala of ‘Celebrity sewing teachers’, which It is not having very good audiences eithera week is postponed. It is unlikely that TVE is looking for a schedule change for ‘La Revuelta’, since it cannot be allowed, as Tele5, to base its entire grill on a single product. But at the moment it can be an experiment to verify how it is given to escape from the motorcycle sponator. Meanwhile, Telecinco triumphs. Although the Mediaset channel is still in total audiences below Antena 3 and the1 (it will be necessary to see if it recovers second place with the spectacular audiences of ‘The island of temptations’ and ‘survivors’ of March), its climb thanks to the Montoya phenomenon is remarkable not only for the damage it is doing to Broncano, but by the improvement itself for the global computation of the channel. And it is not the only strip that improves its data, but that mornings and afternoons have also experienced remarkable increases. Realities Explosives Montoya became Thanks to the power of memes In a global phenomenon, but what Telecinco perhaps did not expect was that it helped to give a tremendous push so much to the final stretch of ‘The island of temptations’ (a spectacular 26.9% quota came to have in its tenth week on Monday, leading every week and with an average of 19.1%). But the phenomenon continues: in its second week, ‘survivors’ already averaged 20.6% of Share in its main section, and exceeds 20% in three of its first editions. Figures completely from another era, almost pre-streaming. Not everything is the islands. And not just that. Last week, Ana Rosa showed that His return to the morning It had been a good idea because it is not only planting face (without destroying, but enduring the envy very dignity) to Arús, but since he left the afternoons, ‘late’ is strengthening his presence. Last Tuesday 11, both Ana Rosa (15.8%) and ‘afternoon’ (10,1) made respective records of Share In his trajectories, and also ‘Jorge’s diary’ (10) strengthened his space, since he has a good run of double -digit audiences, and on Tuesday he made his best fact since its premiere, demonstrating that the change to the second half of the afternoon has sat very well.

In their search to make the increasingly productive olive trees, these researchers have had an idea: to throw coal

The jungle floor is between reddish or yellowish; He is sterile and ungrateful, blinding and distemper. It is plagued with mineral oxides or empty of calcareous materials. It is and has always been a bad ground. Therefore, when in the middle of the Amazon, the settlers met the ‘Terra Petra‘They couldn’t believe it. It was a black, tremendously fertile land, incredibly resistant to the decomposition of organic matter. For decades, nobody knew where he had been able to leave. A dark enigma for a bright future. Some said that the Andes volcanoes could have come, others suggested that they should be a product of sedimentation of the tertiary lakes. But, When analyzing they realized that they were truffled with ceramic remains, fish swords, jewelry and human objects. The miracle of the ‘Terra Preta’ was the miracle of huge agricultural communities mixing land, vegetable coal, organic material of all kinds and favoring the growth of an own ecosystem within them. Charcoal? Indeed. That same face The researchers stayed. The jungle peoples often use a burning system to create fertile soils. The problem is that they lose fertility quickly. With the ‘Terra Preta’ it does not happen and the secret is in that coal. What in jargon is known as ‘biochar’. And that is really working? That is what The European Soil O-Live project has been askedif the olive trees could treat with a mixture of biochar and compost. The result is what brings us here: what Yes it works. According to researchers at the University of Jaén, coal treatment increases oil production between 7 and 24%. That is, between 0.4 and 1.7 kilos of oil per olive tree. It is true that it is a preliminary investigation, but without a very promising place. And what do we want it for? That is, without this type of “treatments” Spain is already the place of the world where more oil occurs and not for: grows 15% per year. The problem is that the machine cannot stop because demand It grows even more. Where will this race take us, that voracity? That is one of the great questions of the century.

China needs cardiologists in an increasingly aged society. His answer is an AI that “reason” as the best

820,000 people. That is the number of patients that the Department of Cardiology of the Zhongshan hospital attended in 2024. A very high figure for a country in which doctors are missing and that sees that, every so often, every so often, His hospitals overflow. Increased higher health coverage, especially for an increasingly aging populationand the answer has been found in artificial intelligence. In a cardiologist, specifically, which has trained with a base of hundreds of thousands of people and has all the support of the government. Cardiomind. That is the name of artificial intelligence that has been developed by the Zhongshan hospital, the University of Fudan and the Shanghai Artificial Intelligence Academy for Science. It is a joint effort to create an AI that, according to them, is able to reason as their best cardiologists. GE Junbo is one of those outstanding cardiologists of the Chinese Academy of Sciences and Comment They are feeding the system with data, but they also teach him “to think as an expert first level cardiologist.” Co-pilot. In this way, Cardiomind compares patient history and the results of tests based on global research to generate diagnostic suggestions. And if you were raising one, leaving the possibility of leaving your heart’s health on the awareness of a machine, in the word “suggestion” is the key. According to its creators, the idea is not that doctors are replaced, but that it helps those members of a congested system to work faster and more accurately. “With their help, our doctors can attend more patients, reduce the workload and improve both the quality of the diagnosis and the treatment,” commented The doctor. Pillars. The secret of the pizza is in the dough, in the case of AI, that special sauce is the training. Cardiomind is a multimodal system that can analyze and process data from various sources (electrocardiograms, ultrasound and laboratory results, for example) to provide its diagnosis, and it is what has been trained. The source has been hundreds of thousands of medical records that the Hospital Cardiology Department had stored for decades, learning in the process how doctors think both in the diagnosis and during treatment. In addition to multimodal and very trained, it specializes in one thing: cardiovascular diseases. Total government support. And all this comes from the hand of itself. China is investing strong in development of artificial intelligences and, although in the West only a few as Deepseek They are the ones that attract attention, the country has been betting for the development of these systems to decongest several organisms. And that of medicine is fundamental. In January of this year, and apart from Cardiomind, established In Shanghai the first test and verification center of large models of AI in the field of medicine. Their fields will be assistance, disease prediction, personalized treatment according to the history of each patient and support to develop drugs. Necessary. Such is that impulse that several hospitals already have their own AI platforms, even some that They combine Contemporary and traditional medicine. And the reason why this technological development is being promoted is the one mentioned above. The population is getting older and doctors are missing. It is estimated that the country has 1.9 doctors per 1,000 inhabitants and They want have 5.5 nurses per 1,000 people for this year. In other countries, the average is devastating. In Spain, for example, there is 6.21 doctors per 1,000 inhabitants. In the case of nurses, the figure is 7.12. Challenges. Now, despite that government impulse, there are three elements to take into account. One is that of the data security to guarantee privacy. In the case of Cardiomind, those responsible developed a firewall with encrypted data. Other countries are studying How to apply AI in cardiology and, precisely, data leakage and ethics is a point that is usually present Among the concerns. Ethics also plays a role, since if it goes from suggesting to a more important role, it would be necessary to legally regulate it. At the moment, or they are in charge “only” of paperwork and records or, if they attend decision making, the last word has a human. In addition, there is the technological issue itself. The development of these artificial intelligences needs servers and calculation power. It is something that China is solving more or less controversial forms buying items that They should not be able to buy due to the commercial war with the West, but also using solutions developed at home, such as the chips of a huawei that is the spearhead in development of hardware for AI in the Asian giant.

Cosmologists are increasingly clear where the most energy particles in the universe come from

Cosmic radiation bathes our solar system, and therefore also our planet, from the moment in which it was formed from A gigantic cloud of gas and dust does more than 4.5 billion years. During most of our history we have not been aware of its existence, so to find the first scientist who told us about the presence of a form of radiation that had to proceed from the outer space we must go back to 1912. The Austrian physicist Victor Franz HESS was the first to identify the origin of a form of radiation whose intensity increases with altitude and its abundance varies with latitude. To carry out his experiments he used probe balloons inside whose measurement devices expressly designed to measure the radiation present in the atmosphere. His valuable scientific findings were rewarded with several awards, among which is the Nobel Prize in Physics, which he shared with the American physicist Carl David Anderson in 1936. Many other scientists continued HESS’s research, and thanks to all of them we know today a little better A radiation form that transports to our planet very valuable information about the universe to which we belong. Kilonovas seem to be responsible for the most energy radiation Cosmic radiation is constituted by high -energy ionized atomic nuclei that move through space at a speed very close to that of light (which is approximately 300,000 km/s). That they are ionized indicates that they have acquired electric charge because they have been stripped of their electrons, but these atomic nuclei are made of the same matter that constitutes us and everything that surrounds us, a quality that reveals to some extent their origin. One of the most important characteristics of cosmic radiation is its essentially perfect isotropy. This parameter reflects that the rays arrive from all directions with the same frequency, which indicates that they must coexist simultaneously numerous sources capable of generating them. And this invites us to ask ourselves one more question: where cosmic radiation comes from. A good part of the cosmic rays we receive comes from outside our solar system. Of other stars An important part of the radiation that permeates the atmosphere of our planet comes from the sun, which, as we all know, is the closest star. However, it is not at all the only source of external radiation that reaches the earth. A good part of the cosmic rays we receive comes from outside our solar system. Of other stars. And travel through space with enormous energy until impacting with the atoms present in the upper layers of the atmosphere of our planet. What astrophysics did not know with certainty until very recently was the nature of the source that originates the most energy particles that we can find in the universe. But researchers from the University of New York have published a scientific study in Physical Review Letters in which they argue that this form of radiation proceeds with a high probability of kilonovaswhich are nothing other than the clash and fusion of two neutron stars to give rise to the formation of a black hole. “After six decades of effort it is likely that we have identified the origin of the mysterious most energy particles in the universe. This discovery provides a new tool to understand the most aggressive events of the universe: the fusion of two neutron stars to form a black hole, the process responsible for the creation of many precious and exotic elements, such as, for example, gold, platinum, uranium, iodine or xenon. Gennys R. Farrar points outPhysics professor and one of the people who sign the study. When they are close enough, gravity takes control and the two neutron stars are condemned to collide Neutron stars are not always lonely. Sometimes one of them is part of a binary system next to a “living” star, and if the appropriate conditions are given, the latter can also become a neutron star. In this scenario the binary system ends up being constituted by Two neutron stars that turn around the other. As time goes by, angular momentum is being lost, which causes their orbits to narrow and approach more and more. And when they are close enough, gravity takes control and the two neutron stars are condemned to collide. The main contribution made by Farrar and their research partners is their defense of the existence of a very close relationship between the energy of the most intense cosmic rays and their electric charge. Their conclusions have to be experimentally endorsed, but they represent a breath of fresh air in a field in which it is not easy to elaborate new knowledge.

It is becoming increasingly clear that there is no “normal” body temperature.

If you ask us what the “normal” temperature of our body is, the instinctive answer will be 37º Celsius. When the thermometer exceeds that mark, we usually talk about fevermild or high depending on how far we move away from the figure. However, over time health experts have realized that the reality is a little more complex. The body temperature issue It is not a mere curiosity. Fever is an important response of our body to many diseases or disorders, generally to infections. The fever It is a double-edged sword: our body raises its temperature to try to kill viruses and bacteria that may be damaging it, while activating our body’s immune response; However, in the process, fever can also put the proper functioning of our organs at risk and cause other problems such as dehydration. Since fever is a common response to various illnesses, it can also cause us serve as a diagnostic toolto narrow the circle on the possible conditions that affect us. Answering the question of what is the “normal” temperature of our body is difficult. And the reasons behind this are several. Firstly, because, over the last century and a half, the estimated average temperature of the human body has been reducing. The notion that our body temperature It is at 37º and dates back to the mid-19th century. In 1868, the German doctor Carl Reinhold August Wunderlich conducted a study using 25,000 patients and more than a million temperature measurements. From these data, he calculated that the average temperature was 37ºbut also observed certain deviations. However, more recent studies have observed lower average temperatures. A recent example of this we found it in a studio Made in the United States and published in 2020 in the magazine eLife. The analysis indicated that Americans’ body temperatures had been dropping at a rate of about 0.03º Celsius every decade. A previous study conducted in the United Kingdom and published in 2017 in the magazine B.M.J.estimated an average temperature of 36.6º in its sample of more than 35,000 participants and 250,000 measurements. We don’t really know why body temperature has been reducing over time. A possible explanation It lies in the improvements in hygiene and immunity, which would imply a lower incidence of infections in the population and therefore lower average temperatures. But this is just one of the various hypotheses that seek to explain the phenomenon. Wunderlich himself observed in his study that men and older people tended to have lower body temperatures, while women and younger people had higher temperatures on average. Which brings us to the second reason why establishing a “normal” reading is especially difficult. And it depends. Sex and age are two of the factors that can make what is “normal” for one person not “normal” for another. But other factors can also alter this figure. a study published in 2023 in the magazine JAMA Internal Medicine measured the degree to which these factors affected body temperature, but also added new variables such as height, body mass, and the time of day at which the measurement was taken. Among the sample of 618,306 observations, the average temperature was at 36.64º Celsius. Among the participants, the average readings for each individual ranged between 36.24º and 36.89º. It is also worth remembering that there are different ways to measure body temperature (tympanic, oral, axillary…) and that each one It presents some slight associated deviations. So at what temperature fever comes? As is evident after what we have read, the answer is that it depends on each person and situation, although fortunately, with the variations being less than one degree, the interpretation of the results of a thermometer may not be as different from the conventional one as to affect decisions such as whether or not to stay home during a cold. However, for health experts, having better knowledge about these variables can be of great help. That is why new studies have also investigated this question. One published in November of last year in the magazine Scientific Reports by South Korean researchers, analyzed the body temperature of 9,195 hospital patients through tympanic temperature measurements (the tympanic temperature It is usually half a degree above the oral measurement and about one degree above the axillary measurement). The team estimated an average temperature of 36.91º Celsius, and a limit of 37.81º for fever.
