recipe

Science has calculated the real impact of reading books on your brain. And it has a very simple recipe: 30 minutes a day

by

It is well known that a sedentary lifestyle It is one of the great enemies of public healthespecially at advanced ages where muscle loss is a great danger. However, there are sedentary activities that are really beneficial and that we sometimes stop, such as reading books. Its benefit is such that science has shown that immersing yourself in the pages of a good book It not only feeds the intellect, but also lengthens life. The demonstration. One of the most important studies who wanted to focus on the benefits of reading, beyond the cognitive benefits or the richness of vocabulary for everyday life, analyzed a group of 3,635 nationally representative participants in the United States over 12 years. And as a result, they saw that the longer the time spent reading books, lower risk of mortality. The results. To understand the magnitude of the discovery, the researchers followed all the patients until 20% of them died and only 80% remained. There they put the cut and began to draw conclusions. The first is that non-readers reached this point at 85 months, while book readers reached this same threshold at 108 months. This is something that translates into a 23-month survival advantage for those who had the habit of reading books, or in other words, readers reduced the risk of mortality by 20% throughout the 12 years of follow-up. Furthermore, this protection was maintained regardless of a person’s gender, wealth, education, or health status. The format matters. Although you may think that any type of reading is appropriate, even the back of a shampoo, the reality is quite different. In this case, the study explicitly compared the impact of reading books versus reading the newspaper or a magazine. The findings here demonstrated that reading books contributes to a significantly greater survival advantage than that seen with newspapers or magazines. While magazines offer short articles that we often skim, books require a higher level of concentration. Something that is enhanced above all because the authors constantly present themes, characters and topics and that is essential to be able to follow the thread of the story that is being presented to us. Because? Here science is quite clear that the key is in the brain, since the “cognitive score” functioned as a complete mediator of this survival advantage. This means that reading books improves cognition and it is this cognitive improvement that prolongs life. Here reading books activates different specific neural processes that create this advantage. Among the most notable points, we find that active reading of books improves skills such as reasoning, concentration, critical thinking and vocabulary. But it also promotes social perception, empathy and emotional intelligence, which can lead to better health behaviors and stress reduction. Fundamental things when we talk about extending life. It’s backed up. In addition to the original study published in 2016, science has wanted to continue investigating the benefits of reading with a study published in 2024 where the complexity of reading in older adults pointed to less cognitive decline. But it has also been decided to analyze even the cultural level of the citizens, where it has been seen that low literacy increases mortalityonce again making the act of reading books stimulate our brain and protect our cognitive reserve. Although it is not necessary to be reading all day to guarantee having a better brain, studies specifically point out that with about 30 minutes a day It is enough to start reaping these advantages and obtain more years of life in which to continue reading.

If you want your body to be biologically eight years younger, science has a recipe for you: vegan diet

by

We humans have many desire to appear as young as possiblealways seeking eternal youth. This has meant that its search has ceased to be the exclusive terrain of the alchemy to become one of the hottest fields in biotechnology, with many treatments that seek to literally make us younger or even extend our lives. Now, the vegan diet It is at the center of supposed iron health, and science has wanted to verify whether consuming it leads to an increase in the years of life. The twin experiment. Traditionally, doing research on how a person ages has been a problem because of genetics. And comparing two therapies between two people to see if they age more or less quickly makes us wonder if the result is due to the treatment or diet or because one of the members has very good genetics. To eliminate this variable from genetics, science has found the best way to work: use identical twins. In this way, their genetics will be exactly the same and the effect of the intervention we perform will be directly related. The study. They recruited a total of 21 pairs of healthy adult identical twins. One of each pair was assigned a healthy omnivorous diet; on the other, a strict vegan diet. In total, for eight weeks the impact was measured using epigenetic clocks with algorithmic tools that estimate biological age based on in DNA methylation. Methylation is the process by which small chemical groups called methyls are added to certain parts of DNA with the aim of being able to ‘turn genes on or off’, causing some instructions to be read and others not. Something that is related to agingsince it changes over time. The results. In this case, what the researchers saw was very interesting, because despite the short time the diet was maintained, it was found that the vegan group showed significant reductions in estimated biological age. This is something that was seen in decreased DNA methylation in pathways related to inflammation and metabolism. All of this adds up to improvements in fasting insulin and a reduction in LDL cholesterol, leading to better old age. But although everything seems very good, caution was already requested with these results. Because. It’s okay that the vegan diet seems to offer good results, but the big question is why this happens. And the summary tells us that it was not just because they left meat aside, but because they stopped eating in general. This is the most important point, because the vegan group consumed fewer calories simply because the calorie density, and therefore the calorie restriction in the end It is one of the few methods which has been proven to extend life in animal models. This also adds up to weight loss, as the vegan participants lost more weight than their omnivorous counterparts. Critics point out that rapid weight loss can alter epigenetic markers on its own, regardless of the food source. The problem. Although the fact of being on this diet for such a short time and under the study means that longitudinal research is still needed to know if this translates into years of real life gained. And although the biological clock slowed down in this case, researchers warn about the long-term risks of having a poorly planned vegan diet. One of the consequences is the vitamin B12 deficiencyalthough today the supplementation that is done in foods makes this a minor problem. Added sugar. The other culprit of aging and to which we pay less attention. A study published in 2024 I was quite clear about the consequences of its consumption, in some cases without knowing it because we did not read the labels of the foods we consumed. In this case, a study with 242 middle-aged women used epigenetic clocks to measure cellular damage to correlate it with their consumption. The results in this case were quite clear: each extra gram of sugar added was associated with an increase in epigenetic age. However, there is a brake that we find in our Mediterranean diet, which is rich in vitamins, minerals and antioxidants. That is why eliminating up to 10 grams of added sugar per day could reverse the biological clock in approximately 2.4 months. The lesson. Scientific literature points out in this case that what matters in food is quality, not just the label. This is why a varied diet with fruits, vegetables or legumes is directly associated with lower mortality and a decrease in chronic diseases. On the contrary, a vegan diet that is based on ultra-processed foods (even if it has very little meat) can be really harmful in the end.

follow the opposite recipe to IKEA

by

The Danish chain JYSK has reached 172 stores in Spain and Portugal after opening 28 new ones last year, already billing 221 million euros. Their plan: reach 300 stores in the coming years. Known as ‘the Danish IKEA’, its big difference compared to the Swedes is that IKEA opens large commercial temples that usually require specific trips as they are in very specific locations, while JYSK multiplies points of sale in medium-sized cities and provincial capitals with smaller stores. Why is it important. JYSK has become IKEA’s great competitor in Spain without trying to imitate it. Its capillarity strategy allows it to cover areas where its rival is not present, capturing impulsive purchases and quick renovations that do not justify a trip to the outskirts of the city. The result: it grows in billing while expanding its network at an accelerated pace. The contrast. IKEA is a planned excursion. JYSK is a casual purchase. The Swedish giant is betting on a few megastores that concentrate thousands of products. The Dane prefers premises of 1,000-1,500 square meters that are more accessible from home. They are opposite models that pursue the same client at different times. Between the lines. The key is in positioning: JYSK sells “hygge“Danish —Nordic comfort—at competitive prices, but without the logistical complexity of IKEA. Reduced catalogue, without exhibition labyrinths. The customer comes in, buys and leaves. The company has 3,500 stores around the world and aims for 5,000. On the peninsula it has invested 12 million euros to create 250 direct jobs. His recent landing in Calatayud (Aragón) is a good reflection of its strategy: it is its fourth store in the community, and it follows a pattern: strategic cities without commercial saturation. The opening in Almenara (Castellón) of a logistics center of 274,000 square meters, with an investment of 300 million, will supply Spain, Portugal and Morocco from 2028. It will be the new headquarters for the Peninsula, with 250 employees and capacity for 182,500 pallets. Yes, but. JYSK is still far from IKEA in turnover: the Swedes earned 1,986 million in Spain last year, almost nine times more. The difference lies in the average ticket: IKEA dominates in large purchases (kitchens, complete bedrooms, etc.) JYSK is strong in partial renovations and add-ons. The question is whether JYSK can maintain this pace without cannibalizing its own stores. Capillarity has a limit: opening too many points in nearby areas reduces profitability. At the moment it works because Spain still has untapped commercial gaps. In Xataka | After DANA, underground parking is under scrutiny in Valencia.

This is the recipe with which they want to turn around the energy map

by

Against all forecast –And in the middle of Trump was in the White House– California is demonstrating that the sun can with the night. The recipe has no technological mystery: a lot of photovoltaic, many batteries and an increasingly fine demand management. The result is that natural gas, for decades the king of the evening peak, yields ground quickly. The key is in batteries. And the state of California is more than clear. The solar generation has increased in this half year by 18% compared to the same period last year and the discharge of batteries grew by 63%, allowing to cover up to a third of the maximum night demand, According to Ember. That cocktail allowed to cover the maximum night demand, a space that until nothing dominated the combined cycles of gas. The impact has been fulminant: the production of gas plants fell 25% in one year and 43% in just two. During the summer, in 41 of the last 49 days, the Californian network was able to meet the entire demand exclusively with solar, wind and hydro, sometimes for more than nine consecutive hours. In several days, the renewable supply exceeded 140% of the demand, with surpluses exported to neighboring states, As explained by Professor Mark Jacobson in an interview with Bruce McCabe. The kitchen of success. The key to the Californian turn can be summarized in a word: capacity. In just four years the state went from having 0.6 GW of batteries at a network scale (2020) to 11.7 GW in 2024, almost half of the entire National Park. That year it installed more storage (3.8 GW) than large -scale solar (2.5 GW), a milestone that reflects the change of priorities, as they have detailed in an Ember report. However, we are not talking only about the hardware of the matter. The Caiso operator He opened the door that the batteries arbitrate intra -diagram prices – cargar when the energy is abundant and cheap, sell in expensive hours – participate in regulation services and reserve part of their capacity for the so -called “critical hours” in the afternoon. In 2024, even with more moderate price peaks, its role in the Net-Peak was consolidated, displacing the gas turbines that used to dominate that section. Two factors that have helped. On the one hand, solar roofs already produce the equivalent of 13% of the electricity sold in the state, reducing the daytime demand of the network and, when combined with domestic batteries, also the nocturnal. On the other hand, the Demand-Side Grid-Sport (DSGS) program has given rise to one of the world’s largest power plants in the world, with more than 200 MW operations and 720 MW of customer batteries. In the summer of 2024 it was activated 16 times during heat waves and tested its stabilizer effect. However, its future is uncertain: the state budget deficit and a cut of 18 million dollars put both DSGS and the Microredes Deba program at risk, warns PV Magazine. The impact on prices. The most immediate result for consumers is that prices have relaxed. The renewables sank the wholesale cost: the spot fell 53 % year -on -year and many noon sections recorded negative prices, damping thanks to the fact that the batteries already absorb 15 % of the demand in those hours. According to Jacobsoncomplete electrification can save between 60% and 65% of the annual energy invoice compared to the current fossil -based model. All pink color? No, California still faces challenges. Demand response programs depend on public budgets that are not guaranteed. As Jacobson has pointed out In a study published in Standfordthe network needs to continue improving its flexibility: move hydroelectric to the night, accelerate marine wind and strengthen demand management are essential steps. Spain: The other face of the currency. While California wins the gas battle, Spain lives the opposite paradox: it produces more renewable than ever, but cannot only trust them. After the blackout of April 28, 2025, Red Eléctrica activated a reinforced operational mode which prioritizes combined cycles. The problem is not the lack of sun or wind, but storage and flexibility. Without enough batteries or hydraulic pumping, the network lacks mattress to transfer the noon surplus at night peak. The Government knows and has reacted with an “antiaps insurance”: Royal Decree-Law 7/2025 He opened the door to capacity markets that remunerate firm technologies for being available. The objective is to maintain 9,000 MW of combined cycles that were at risk of closing. But those are temporary crutches. Structural solutions – batteries, hydraulic storage, micro -redes and demand management – will take at least until 2026 to deploy. Two roads, the same lesson. Mark Jacobson He foresees California will reach 80% renewable between 2026 and 2028 and 100% between 2030 and 2033. Ember He estimates that in 2025 A batteria GW will be installed for every 1.7 GW of solar, further accelerating gas replacement. The moral is clear: California demonstrates that miracles or futuristic technologies are not needed: with solar, wind, hydro and batteries enough to bend gas. Spain, on the other hand, remembers that the transition is not improvised: without sufficient storage or management, renewables cannot sustain the network alone. The road is clear; The question is who will travel faster. Image | Rawpixel Xataka | 99% of the Internet travels through submarine cables.

There are more and more and better plugs for electric cars but Tesla continues to lead. The recipe: cheap and reliable loaders

by

Holy Week of 2024. Dozens of Tesla cars They queue in a Cañavate Atalaya charger (Cuenca) in the middle of any place. The situation went viral and because scenes were repeated in Mérida and Albacete. The waiting were 15 or 20 minutes in many cases but also exceeded the time in others. They all had something in common: Tesla Load Stations. Despite the jokes and despite the intention of ridiculing the owners, in Xataka We broke a spear in favor of those drivers And we count why they had happened. If Holy Week has taught us, it is not missing chargers for electric cars. What are missing are reliable plugs. So we titled. Year and a half later, things have changed. Not only in Spain, also in the United States. But, nevertheless, Tesla still has the best load experience. And that is still key when selling the car. Tesla chargers are still ahead The data this time comes from the United States but the situation is extrapolable to what happens in Spain. JD Powerspecialists in motor market analysis, has analyzed the status of the United States recharge network and its conclusion is very simple: there are more and more chargers available and increasingly spoil. But Tesla continues to lead, with much, satisfaction among electric cars when you have to recharge a vehicle. Keep in mind that the United States has a huge Loading deficit. Especially if we consider that distances are huge. If the country is wanted to embrace the electric car to a greater extent it is necessary to create a good network of loaders as fast as reliable. A good part of that network is now in the hands of Tesla, where most users load. They do not even have a Tesla. The latter is key to understand why satisfaction with the price of loaders and the load experience has fallen in the last year. According to their data, drivers are less happy with both points because they observe that, for them, prices are more expensive and the most rough experience than for Tesla users. Something curious occurs, therefore. According to JDPOWER, the level of failed visits (the charger does not work correctly or is out of service) is the lowest in four years and the number of drivers who have reported these failures (14%) is also lower than in 2024. General satisfaction, however, has fallen. The Tesla Network is so good compared to the competition that the users themselves have pressed to the manufacturers of other cars to the point that they have assumed the Tesla standard to load, modifying their own cargo ports. The best user experience In Spain (and Europe) that is not so because fast loaders are all (except for the first Japanese cars) CCS2. That is, the plugs are the same for everyone. But Tesla’s experience is still above. To understand it, we resume the case of Holy Week in 2024. This year the same have not been observed issues. Or not, at least, with the same seriousness as last year. It is logical, as we said that happened. Tesla has “kidnap” the owner of his cars in his own ecosystem. Tesla did something very intelligent since her birth. It was as simple as proposing their own load stations. Thus they guaranteed to give a confidence network to those who made the leap to a completely new company (and technology). They also took advantage, to create synergies of which the rest of the manufacturers have not arranged. First, his recharge were free. Now that is a thing of the past but their prices are still lower than those of the competition. This guarantees that, in the day to day, the Tesla user prioritizes the load in their stations. But saving a few euros on a very specific day is no reason for users to prefer to spend more than an hour stopped before recharging the vehicle. If those queues were formed, it is because the Tesla recharge network is very reliable. In fact, myself when I try the cars of any company for our reviews soil to prioritize Tesla plugs Because they have never left me. Only Zunder has offered me this same experience. With the rest of the companies I have had problems of malfunction or inoperance. It is logical, therefore, that if a Tesla driver has hurried the autonomy of his car is reluctant to go to another load point, consume a good part of the little percentage that remains reserved and risks that the plug of another company does not work. He will think: “Better wait here for an hour than to go to another place, Not being able to load and have to call the crane“ To this we must add that Tesla’s user experience is the best because they have eliminated small frictions that are very appreciated on a day -to -day basis. It is something similar to Apple’s ecosystem. Can you have a Mac, an Android phone and use some AirPods in the latter? Yes, but there are small barriers that the average or little advanced user will hurt especially. The same goes for the electric car. Tesla has one of the best software in the market and, probably, the best route calculator. Prioritize your chargers and show you in real time the occupation of it and advances a possible wait. When you arrive, the vehicle detects the loader, opens the load gate and plugs the hose in the car. When it is time to continue, the mobile phone warns you and as the car is associated with a credit or debit card, nothing must be done. The position will be passed. Simple. When one carries in Tesla supercargers with another car you have to Log in the mobile phone and select the load point you will use. You have previously had to register the card. Finally the position will be passed. This process has to repeat it with Each and every one of the companies … Read more

How to get recipe ideas and what to cook using artificial intelligence

by

Let’s explain How to get recipe ideas using artificial intelligence. This will offer you different ways to get ideas and recipes to know what you can cook, both asking for something concrete that you want to prepare how to do it based on what you already have in the fridge, or preparing weekly menus. For most cases we will use the tools of the common and known by all, such as Chatgptalthough you can also use COPILOT, Deepseek, Gemini or similar. For these tools we will give you different ideas to use them When asking for ideas and recipes. But in addition, in the end we will also include some other applications that may interest you. Before starting, things to take into account Before putting artificial intelligence to help you with your recipes, it is important to take into account some things. First of all, You must know your food restrictions or those of those people for whom you are going to know. You must know the allergies, intolerances or their specific diets, and then try to use tools that take this into account, or specify it to the AI with which you are going to make the recipes. It is also important know what ingredients and kitchen utensils you have at home. There are some functions that will help you with the issue of ingredients and that we are going to tell you, but in general it is important to have an idea of what you have and what does not. The same goes for kitchen utensils. It is also important have your goals in mind. By this I mean you think if you want a quick recipe, one with few ingredients, or something more elaborate. These are things that you will have to specify when you then do the requests to artificial intelligence. And two more tips to finish. First, Do not trust the recipes that gives you AI, especially in terms of quantities and others. The more complex they are, the more possibilities there are errors. But on the other hand you should also have an open and flexible mind, since it may make creative suggestions or suggest uncommon ingredients. Ask for a specific recipe The easiest way to use AI to get ideas about what to cook is Ask for a specific recipesomething that you want to cook. You can take advantage to use a prompt in which, in addition to specifying what you want to do, you ask you to make an ingredient list and a step by step. For example, you can ask for something like this: I want to cook (the dish you want), tell me the best recipe and its step by step, and also give me a list of the necessary ingredients. With something so simple, chatgpt or the AI you have selected will become a kitchen book. First he will tell you the ingredients and quantities, and then he will indicate step by step all the elaborations. Ask for ideas by type of food Sometimes the problem is that you don’t know what you want to eat specifically, but you can ask for ideas for the type of dish you want try to prepare. Here, as we have told you in the previous advice, it is important that at least you can give it a few indications, and the more they are the more it can be right. For example, you can say: I need ideas for dinner. Tell me things that can prepare that they are fast, fresh, healthy and that you do not need too many ingredients. As you can see, in our request we have used four terms to describe what we want, and with that it has already given us several ideas such as chickpea salad, zucchini tortilla, and so on. You can use this same formula but changing the terms for others that adapt to what you want. Write ingredients and ask for ideas The next level when asking for ideas and recipes is tell the AI what ingredients you have availableeither in the fridge or in the pantry, so that the recommendation you receive is based on them. You can use a prompt like this: In the fridge I have eggs, tomatoes, potatoes, lettuce and a little chicken. Tell me fast that can prepare for dinner. Only with that, the AI will suggest several different dishes that you can prepare. In each one it will tell you the necessary ingredients and will take the steps of the preparation, including the times. You can get two or three fast ideas with this method, and almost all AI as chatgpt can serve you. Teach him what you have in the fridge Both Chatgpt and Gemini and some other artificial intelligence bots have photo recognition. This allows you Upload a photo of your fridge in which you see what you have, and then ask you to ideas about what you can cook with what is there. This is what I have in the fridge. Give me ideas of dinner dishes that can cook with it. If you put this prompt and also attach a photo, the first will identify the ingredients you have, and then it will make you several suggestions about cooking things based on what he sees in it. You can make corrections, or say “I also have ham”, or mention another ingredient you have and do not look good to receive new suggestions. Artificial intelligence can also help you Plan your week with weekly menus. You will even be able to make AI make a purchase list with all the ingredients you need for all dishes. A starting point could be this: I need you to make me a weekly menu, with breakfast, food and dinner. That is a balanced and healthy menu, where the Mediterranean diet prevails. Also make me a list of ingredients necessary to make the weekly purchase. Here, as we have told you, You can specify all kinds of … Read more

For centuries the blue pigment recipe used by the Egyptians had been a mystery. We just solved it

by

Not all Treasures They are made up of jewels, gold and precious stones. For a long time a group of researchers from Washington State University It is behind of a treasure equally fascinating but much more elusive: the Egyptian bluethe synthetic pigment older which is recorded and that once used the artists of the ancient Egyptian to decorate from alabaster bowls to coffins, ceramics and murals. Despite their enormous popularity and that the Romans continued to use it, their recipe was lost over the centuries. Until now. What is Egyptian blue? One of those mysteries that has been intrigued by archaeologists in half the world. Egyptian blue is basically a dye that stands out for two reasons. The first, because it is the synthetic pigment older known to date. It was used thousands of years ago. The second is its bluish tone, which allowed artists to use it as a much more expensive mineral substitute, such as turquoise or lapislázuli. With everything and although we talk about “Egyptian blue” in general, the pigment was very heterogeneous. Depending on where it would have been manufactured, how it would have worked with the material or quality of its components, the tone could vary between gray, a more or less deep blue and a green off. A factor that influenced the process for example was how quickly cooled the mixture. How old is it? Quite. We know that Egyptian blue was already used 5,000 years ago. And that at least. In fact The oldest sample Known is a small alabaster bowl made in the 3250 AC The pigment was used in ceramics, sculptures, murals, sarcophagi, pieces that we still keep today and show its bluish hue. It was also applied to different surfaces, such as wood, stone or cardboard, a material similar to Paper Maché. Did you only use the Egyptians? No. His color liked the artisans so much that the Romans ended up incorporating it into their palette after the conquest of the ancient Egyptian and came to be used during the Renaissance. The Smithsoninan Institute remember that a few years ago it was discovered that at the beginning of the 16th century Rafael used Egyptian blue in the fresco ‘Galatea triumph’a work elaborated for the Villa Farnesina, located in the neighborhood of Constévere, Rome. Although Rafael’s intention could be to imitate the old Roman technique, the Washington State University (WSU) Precise that during the Renaissance the pigment formula had practically fallen into oblivion. That is what a team of researchers has now wanted to solve led by the American institution and who has worked side by side with the Carnegie Museum of natural history and the Institute of Conservation of the Smithsoninan Museum. And how have they done it? Based on trial and error. And try again and again until you give in the nail. The team He thoroughly examined Pigment samples and elaborated 12 recipes in which he experienced with different raw materials and elaboration times. The results have been reflected in An article Posted in NPJ Heritage Science in which he details how he worked with mixtures of silicon, copper, calcium and sodium carbonate dioxide. The main ingredient is the cuprov. To complete the process, the mixed mixture warmed 1,000º Celsius For different times, between one and 11 hours, in an attempt to replicate the temperature with which the ovens of the time work. The resulting samples were also cooled at different speeds to then study their pigments through microscopy and analysis techniques. The results were compared to real pieces of ancient Egypt. Is it so complicated? Beyond the materials used or the techniques with which they were mixed, the great challenge for archaeologists has been to replicate the exact tones that Egyptian artisans worked. “One of the things we observed was that with small variations in the process very different results were obtained,” John McColy commentsone of the authors of the study and director of the School of Mechanical and Materials Engineering of the WSU. “There were people who made the pigment, he transported it and then used it elsewhere.” During their study the researchers in fact discovered that to obtain the most bluish hue, only half of the components that generate the blue color were needed. “It doesn’t matter what the rest contains and that surprised us”, Add McCloy. “You can see that each particle contains a lot of elements. It is not uniform, much less.” To such an extent that the WSU acknowledges that one of the conclusions reached by the experts is that the pigment is surprisingly diverse. Did you achieve your goal? That seems. In A statement Run a few days ago the WSU says that after trying different formulas and examining the results in detail, its team has managed to “recreate” the famous Egyptian blue. The feat is not only the result of curiosity or advance to better understand the art of the ancient Egyptian. WSU herself recalls that in part the renewed interest in the Egyptian pigment responds to more pragmatic reasons. “In recent years, interest in this pigment has resurfaced due to its optical, magnetic and biological properties, with potential new technological applications,” Point out The institution. “The pigment emits light in the nearby infrared of the electromagnetic spectrum, invisible to the human being, which means that it could be used for purposes such as traces and create anti falsifications.” Images | Washington State University, Matt Unger, Joshua Franzos and Carnegie Museum of Natural History In Xataka | A 2,000 -year -old cup has revealed an unexpected facet of the Egyptians: psychedelic cocktails

The University of Oxford has found reservations of an energy source for 170,000 years. And he has the recipe to exploit them

by

In a world that seeks to leave behind fossil fuelsthere is a gas that has begun to be outlined as the promise of A clean future. Its potential as an inexhaustible source of Green energy It has aroused both enthusiasm and frustration: producing it without contaminating is still expensive and technologically complex. However, a group of scientists could have found the key to hydrogen under our feet, from the very depths of the earth. Clean gold underground. We have told it On other occasions. Hydrogen has been long promoted as a key piece in the transition to a future without emissions, but also as an essential resource for modern life: in addition to being a clean fuel, it is indispensable for produce fertilizers that support half of the world’s population. The problem? That 99% that is used today It comes from hydrocarbonswhich represents around 2.4% of global carbon dioxide emissions. With a projected demand of 90 million metric tons in 2022 to some 540 million in 2050the challenge is monumental. Until now, cleanest solutions (Like electrolysis with renewable energies or carbon capture) have failed to be economically competitive. Here appears the new Oxford study Posted in Nature: The earth could have solved the problem for us millions of years ago. An unexplored reservoir. In this way, Oxford researchers together with professors at the University of Durham and Toronto have revealed that the continental cortex of the Earth has generated, throughout the last geological millennium, sufficient hydrogen amounts to supply the energy needs of humanity For at least 170,000 years. This immense reserve, natural and emission free, remains largely trapped undergroundintact. Although until now the measurements were sporadic and scattered, the New job It offers for the first time a coherent framework, a “map” if you want, to locate these reservoirs: a “Exploration recipe” (They call it) that details the types of rock, temperatures, fluids and geological conditions necessary for hydrogen to form, migrate and be trapped in exploitable deposits. The approach is not theoretical: it is designed to guide the commercial search for natural hydrogen globally, with the potential to radically transform existing energy models. Ingredients, processes and threats. Such as Professor Chris Ballentine explained in a statementleader of the study at the University of Oxford, finding hydrogen in the earth’s crust is like baking a sufflé: if one fails in any component (quantity, temperature, time or type of rock), the result will be useless. The study Identify the factors that allow a geological hydrogen system to be viable: from the chemical reactions that generate it, to conditions that destroy itlike the presence of certain underground microorganisms that feed on it. This biological threat, indicated by the co -author Barbara Sherwood Lolar, forces to avoid areas where underground bacteria can consume hydrogen before it can accumulate in usable concentrations. Ubiquitous, diverse and list source. There is much more, since The work It also disassembles previous myths on the origin of hydrogen, discarding as unfeasible the sources from the mantle terrestrial and focusing attention on common formations of the continental cortex. These can be both recent (of some millions of years) as an eldest, and are distributed globallywhich greatly expands the geographical exploration potential. Plus: the crucial, They sayIt is not to find a specific type of rock, but to understand the interaction between the chemical, thermal and historical conditions that favor the generation and storage of gas. From theory to action. Aware of the strategic value of their findings, the authors have founded the Snowfox Discovery Ltd.a company dedicated to locating natural hydrogen reserves with social impact. Its objective is clear: to find competitive, clean and sustainable sources of hydrogen, capable of replacing highly polluting current production and feeding the global energy transition without the need for expensive industrial processes. Yes Geological recipe Developed by these researchers, it can be repeatedly repeated in different regions of the planet, we would be facing the closest to an energy revolution … underground. One that does not require new futuristic technologies or dreams of merger, but simply learn to hear THE SECRETS THAT THE EARTH He has been whispening For hundreds of millions of years.

There is no miraculous recipe that gives us a “natural ozempic.” But science has some “tricks” that can help us

by

The popularity of the semaglutida (the active substance of the well -known Ozempic) and similar compounds, has led many to the search for alternatives that allow replicating Its effects without having to go through the pharmacy. It is not something to miss, like any other drug, Ozempic and similar medications have side effects, not to mention their cost or the fact that it can only be acquired with medical prescription. Having more alternatives within our reach can be tempting. The search for a “natural ozempic” however has more shadows than lights, more pseudoscience than science. That does not mean that the door is completely closed. One of the compounds to which often It has hung This label It is the Berber. Although some studies have detected pharmacological effects of this compound, we lack solid evidence today that proves to help us lose weight. What we do have is A series of risks associated with its consumption. Another regular candidate to serve as “natural ozempic” It’s green tea. Although this drink can give us some nutrients and help us stay hydrated, its effects on or on our glycemic levels They are limited at best. In An article for The conversationMary J. Scourboutakos, an expert from the University of Toront A “Ozempic of Nature”. The key to her is not in a compound that these foods can give us, but to focus on those who in one way or another stimulate the production of hormones that these treatments “imitate.” To understand it, we must remember how these compounds work. Semaglutida is an agonist of peptide receptors similar to type 1 glucagon (LPG-1), that is, it is a compound that functions as this key hormone for our digestive processes. The LPG-1 is a hormone that our stomach segregates when we eat with the aim of transmitting a double message. On the one hand, this hormone warns the pancreas that you should begin to segregate insulin to control blood sugar levels. These types of medications are, in origin, drugs against diabetes that stimulate insulin production for glycemic control in people who have trouble exercising this control. On the other hand, this peptide also sends a message to the brain: satiety. This is the reason why these compounds also make those who consume them lose weight, since they flatten hunger. Other drugs, such as Zepbound, They work similarly. The formula of the American Eli Lilly is based on the tirzepatida, which acts as an analogous not only of the LPG-1, but also of the GIP (polypeptide gastric inhibitor). Not only what, also how According to Explains Scourboutakosour diet can help stimulate the production of the GLP-1 hormone. He does not only through nutrients but also through our habits, when and how, in addition to what. With respect to nutrients, the expert highlights two, being the first, and perhaps the most important, fiber. The fiber is key Because it serves as food to our intestinal microbioma, and this in turn would be responsible for segregating compounds capable of stimulating hormone production. A study Posted in 2018 in the magazine Science He indicated that the fiber could help feed bacteria in charge of segregating short-chain fatty acids, which would be in this case those responsible for encouraging the secretion of the LPG-1. Recently, Another studyis published in Nature Microbiologyobtained similar results. The team responsible for this analysis detected that greater Presence of bacteria Vulgatus bacteroids and of its metabolite, vitamin B5 or pantotenic acid were able to activate the secretion of the peptide similar to type 1 glucagon. Returning to Scourboutakos articlethis highlights another key nutrient, monounsaturated fats, which we can find for example in the olive oil. Again, some studies support this notion, such as The published in 1999 In the magazine The American Journal of Clinical Nutritionwhich detected that olive oil stimulated better than butter the secretion of both LPG-1 and GIP. Regarding the “How”, ScourboTakos quotes for example A study In the magazine Diabetologyfrom which he concludes that consuming the most protein foods before the richest in carbohydrates (such as eating a fish dish and then one of rice) would give rise to a greater secretion of LPG-1. Other relevant factors mentioned by Scourboutakos include the time we consume food and even if we chew or consume in a liquefied form. Our diet affects our health and our well -being in very diverse ways. It may seem anti -limitic, but the closest thing to a “natural ozempic” we have is A varied diet, rich in fibers And in fats such as olive oil, whose positive properties have been well known for a long time. A diet of this type may not be able to cure diseases, but it is a necessary complement to many treatments and is an important preventive tool when avoiding problems for the future.

Four days of office and smaller equipment has been your recipe

by

Intel, one of the historical giants of the sector, has started its reorganization After the recent change in the company’s dome. Its new CEO, Lip-Bu Tan, aims to lighten the company’s structure to make more resources. For now, you started reducing Intel template Fireing 20,000 people. But it is not the only change in labor matters that the workers of the American multinational will face, who will bet on a hardening in the policies back to the office and the rationalization of meetings, according to a memorandum signed by his CEO. More office and less bureaucracy. In parallel to the layoffs already announced by Intel, the processor manufacturer has announced a hardening of the office policy As of September 1. With this announcement, Lip-Bu so urged their employees to go to the Intel offices four days, instead of the three days they fulfilled so far. “When we spend time together in person, more participatory and productive debates are encouraged. More effective and fast decision -making is facilitated. And our connection with colleagues is strengthened,” he wrote so to his staff. In the words of its CEO, this measure seeks to “flatten the organization” and strengthen collaboration and speed in decision -making, elements that the new address considers strategic to recover its position in the market in front of rivals like Nvidia or Taiwan companies. Intel’s “zuckerization”. Intel’s new executive director’s criteria is aligned with the strategies of Optimization and efficiency which goal has been applying since 2023. “Many teams have eight or more levels of complexity, which generates an unnecessary bureaucracy that slows us. I have asked the executive team to review their respective organizations, with the aim of eliminating levels, expand the areas of control and empower the best employees,” he said so in his statement. The positioning of such It is not new at all. In fact, it is the same structural thinning approach that all great technological ones such as Google are applying, MicrosoftAmazon and, of course, The flag bearer From this strategy, goal. Intel does not wear chainsaw. In any case, and despite sliding the need for layoffs to improve the productivity and competitiveness of the company, its executive director emphasizes that it will not do it at any cost. “We must balance our reductions with the need to retain and recruit key talent. I will train each of my leaders to make the best possible decisions, aligned with our main priorities,” he wrote so. The new course of the company puts in the center the engineering staff, something that makes all the meaning taking into account that its product is the processors. All the measures that Intel ensures that it will take will be aimed at improving the productivity and efficiency of these equipment. As well as paying special attention to the Talent collection and retention In those profiles. Changes in the way of measuring. Intel’s CEO has made it clear that its intention is to end the old hiring dynamics, in which it was not hired by operational necessity, but for fulfilling a series of performance indicators (KPI) for managers. A practice that, either when hiring either When it comes to saying goodbyeThey have used great technological ones in recent years. “I was surprised to know that, in recent years, the most important KPI for many Intel managers has been the size of their teams. From now on, this will not be so,” he said so in his statement. “I firmly believe in the philosophy that the best leaders achieve the maximum with the least number of people. We will adopt this mentality throughout the company, which will include empowering our best talents to make decisions and assume greater responsibility in key priorities.” In Xataka | The return to the office has had a devastating effect for the concentration of employees: not 30 minutes without distracted Image | Intel
