China already has one of the most advanced observatories on the planet to hunt the most elusive particle that exists

by

Neutrinos are The most elusive particles of nature. They were first described from a theoretical point of view in 1930 by Austrian physicist Wolfgang Ernst Pauli, one of the parents of Quantum physics (We owe, among other contributions, known as exclusion principle). However, its experimental discovery took place two and a half decades later, in 1956. We owe it to American physicists Frederick Reines and Clyde Cowan. There is a forceful reason that explains why these particles are so difficult to detect: They barely interact with ordinary matter. In addition, its mass is very tiny, its electric charge is neutral and are not influenced by strong nuclear interaction or electromagnetic force, although due to gravity and weak nuclear interaction. There is no doubt that they are very special particles. Scientists often illustrate how difficult it is to capture a neutrino explaining that every second trillion of these particles go through both the earth and us without colliding with any other particle. You can also illustrate how elusive that they are using quantum mechanics, which ensures that it would be necessary to manufacture a lead plate with a light year thickness to ensure that half of the neutrinos that go through it collide with the particles of the lead block. The Jiangmen Observatory is ready to hunt neutrinos Despite how elusive neutrinos are, we have several observatories that are able to detect them. One of them is The Japanese Super-Kamiokande. This installation is located in Hida, a city located in the central area of ​​Honshu, the largest island in the Japanese archipelago. It is built in a mine, 1 km deep, and measures 40 meters high and another 40 meters wide, which gives a volume similar to that of a fifteen floors building. However, the authentic protagonist of this article is the Underground Observatory of Neutrinos of Jiangmen, which is housed in the Chinese province of Guangdong. Like the Super-Kamiokande Japanese, Juno, which is how this Chinese observatory is known for its English denomination (Jiangmen Underground Neutrino Observatory), It is a real monster. His heart is a cylindrical pool 44 meters deep that is housed in an underground chamber with granite walls. The neutrin detector consists of a 41.1 meters in diameter stainless steel mesh that supports an acrylic sphere of 35.4 meters in diameter The neutrin detector consists of a 41.1 meters in diameter stainless steel mesh that supports an acrylic sphere of 35.4 meters in diameter. This container is full of a very exotic liquid expressly designed to interact with neutrinos and produce a light of light that can be detected. Juno contains no less than 20,000 tons of this liquid, which allows him to erect himself as the largest neutrin detector on the planet. The composition of this fluid seeks to maximize the amount of light generated by the interaction of each neutrino. Its three fundamental components are linear alkyl benzene, which acts as a solvent; 2,5-difeniloxazole, which is the molecule that is excited when a neutrino interacts with herwhich causes the emission of a flash of light; And, finally, 1.4-bis (2-methylstiril) benzene, which absorbs the ultraviolet light that emits 2.5-difeniloxazole and re-enters it with a longer wavelength that is easier to detect. The flashes of light are collected by 45,000 photomultiplier tubes that cover the inner surface of the sphere. By measuring the intensity, position and duration of these flashes, scientists can reconstruct the trajectory and energy of each neutrino. And all this for what? Wang Yifang explains it to usJuno spokesman: “This observatory will allow scientists to address fundamental questions about the nature of matter and the universe.” Neither more nor less.

11 functions and tricks to squeeze the new characteristics of chatgpt

by

We are going to give you several tricks and tips for Squeeze GPT-5 to the maximumthe latest version of the model of artificial intelligence that uses Chatgpt To work. With this new version new functions and characteristics have also arrived that we are going to teach you to squeeze. GPT-5 is available for all Chatgpt users, both free and payment, so many of these functions will serve you in both cases. Of course, you know that if you are paying you can use more times some of the key aspects, such as photographic edition. But before starting, remember that the first improvement is always reliability, so Chatgpt now responds more reliably. We are not going to focus on that, but I will remind you that the best is always Do not lower your guard with the answersand always check what he tells you, because some data and information may be incorrect. You no longer have to choose specific model In previous versions, the same GPT had different versions, some to give faster answers and others to better reason these answers. Now, GPT-5 is a unified modelwhich means that you no longer have to spend time on this choice. Now, what happens is that you write to chatgpt what you want, and The AI ​​choose which of its ways to use depending on the difficulty of the task or context. Of course, there is a small trick, and it is that You can give a signal to use a model concrete adding things like “think more like this” to activate the reflexive mode. Come on, you can do it manual. Soser context for your chats Another of the functions of GPT-5, like every new version, is Expand the context and memory. If GPT-4 had up to 8,000 context tokens, GPT-5 has up to 128,000 tokens in its most advanced version, which become almost 96,000 words. Free users have about 8,000 tokens, which are approximately 6,000 words. And how can you take advantage of this in practice? Well, to have longer conversations without chatgpt, forgetting what was said above, or to be able to copy and paste much longer texts as complete items or reports, and that can analyze it. Use multimodal understanding Another characteristics of GPT-5 is The improvement of its multimodal capacity. This means that in addition to text, you can also process images, graphics, diagrams or even video sequences. GPT-4 could already describe images in a limited way, but now you can reason about them in a broader way. With this, you can add images or graphics and ask Chatgpt questions about it and its content, or even a summary. By power, you can Upload the photo of a book page and ask you to read it and tell you key pointsso that I can extract the text from that image and summarize it. You can also help with mathematics and sciences. Chatgpt can handle several images A small tip about its multimodal understanding is that GPT-5 can handle mçultiples images If you contribute them in a sequence. For example, you can send two images and ask that you make a comparison, and the AI ​​will understand the context of both of doing so. In addition to creating them, you can edit images Chatgpt has improved its image creation capacity with GPT-5. On the one hand, this means that creation has been improved of images from scratch from your descriptions. In addition, as at the same time has improved the analysis of images you upload, when you ask to reimagine a photo to create an image from it you will also notice that quality has improved a lot. But in addition to that, a trick is that Chatgpt can now edit your photos In several ways. For example, you can ask you to eliminate elements of a photo such as people or some object that bothers, or add elements such as putting mustache in the photo. Create programs and games and use them in chatgpt One of the best GPT-5 characteristics is that not only has its capabilities improved to generate code in several languages, but also allows you to preview what you have created with the. Come on, you can launch the Catgpt’s own code. Imagine you put yourself Create educational games with artificial intelligenceor even Create Rouleta de la Fortuna and Pasapalabra games. When you describe that you believe a certain game and give it the details, chatgpt with GPT-5 will generate the code, and when it ends You will have a button Execute the code which allows you to play what you have created directly in Chatgpt. Take the fullest the new voice mode Voice conversational experience with Chatgpt has improved with GPT-5, and all users have access to the advanced voice mode. Free users can use it for a few hours a month, and those of payment have an almost unlimited use. The understanding of what you say and the way you respond has also improved. One of the things that allows you to do this is use chatgpt as a language teacher. Come on, you can establish the conversational mode to practice a languagetelling him to make the role of a teacher and have a conversation, correcting the mistakes you make when speaking. You can also use it as a real -time translator, and for much more. Finally, remember that chatgpt is multimodal, and that applies to the voice mode. If you are having a spoken conversation, you can upload an image and ask you questions about it, so that you answer you by voice. Chatgpt now has a mode of study Another novelty of the new GPT-5 is the Chatgpt study mode. It is a modality that you can activate so that, when you ask you a question, Chatgpt does not limit the answer. Instead, It will help you step by step to find the solutionor you will prepare exams and questions. Come on, with this mode the AI ​​organizes the information … Read more

Windows 95 still supports an essential part of this company in Germany. The question is how much more time it will endure

by

At this point, almost everyone knows that Windows 10 You have the days counted and your support will go out soon. Microsoft pushes strong Windows 11but the jump is not free, Hardware requirements They raise a barrier that forces many to renew their teams. In terms of security, the recommendations are clear, staying in a system without support means exposing yourself to failures already vulnerabilities without solution. That is the general framework. And, yet, there are stories that call into question the manual and force us to look at compatibility from another angle. The theory says that no one should continue depending on systems that were obsolete decades ago. The practice is different. In Germany, WDR accountan agricultural business works thanks to specific software that runs on Windows 95, a system that in August was 30 years old. The critical part of the line rests on a chain of compatibilities that supports production and traceability. Migrating sounds logical, but each change threatens controllers, peripherals and calibrations. That is why the dilemma is not nostalgia, it is operational continuity in a plant that cannot be stopped. When the business depends on 1995 We talk about a farm with a machine that dominates the entire processfrom the entrance tray to the final packaging. The flow is millimeter, the eggs are advanced, weigh, are labeled by quality and are distributed in commercial formats of six and ten. Coordination carries it A software developed for the machinewhich works on Windows 95 and uses its environment to interact with sensors and peripherals. That coexistence explains why the business is still tied to a system thirty years ago, changing a link can mismatch the entire chain. If the system falls, the mechanical line will continue to move eggs, but the entire digital record disappears. Traceability would have to be done by hand, with more work and more error risk. The fact that the equipment is not connected to the Internet reduces certain threats, but does not eliminate other more prosaic, old hard drives, discontinued printers or electrical components exhausted by use. At that point, the problem would not be a cyber attack, but the difficulty of finding a spare time to keep production alive. Stability is real, resilience is less. The cost of replacing the line goes far beyond buying a new machine. According to the person in charge, it is equivalent to the investment necessary for a family house, an amount that many farms cannot assume suddenly. In addition, the substitution requires paralyze production For weeks, certify processes and return to the staff. Maintaining the current system is not free either, it forces components that only exist in second -hand catalogs. The decision becomes a balance, millionaire modernization or artisanal maintenance of the inherited ecosystem. The case is used for those who plan Windows 10 to Windows 11. The end of support is forcing companies of all sizes to audit inventories, drivers and internal applications before moving card. The lesson is simple and demanding at the same time. Forcing the update without validating the complete chain can break critical processes, while being motionless eternals risks and dependencies. Between both ends, the road map goes through measuring, testing and migrating in phases, with clear priorities and reversibility. The global photo confirms it. FAA in the United States promotes a renovation that points to Remove obsolete technologies in air control systems and leave behind the use of floppy. Japan closed in 2024 the era of disk in the administration after a regulatory cleaning that eliminated hundreds of procedures that demanded it. And in San Francisco, the Metro operator has financed replacement of a railroad control that still depended on loading software From disks. The pattern is repeated more than it seems.

The world has been marveling for decades with the urbanism of Washington DC was actually admiring Aranjuez

by

To Washington DC, the capital of the most powerful nation on the planet, we have seen it in news, photographs, documentaries and films of all kinds and condition. It is not unreasonable to think that if there was a ‘top 10’ of the most represented cities in the world, the American would occupy a relevant place. However, despite that huge overexposure, one of its greatest architectural secrets has gone unnoticed until now: at least a key part of its urban planning is inspired by a Spanish town that does not reach the 63,000 inhabitants. Which? Aranjuez. Reviewing the story. That the Royal Site of Aranjuez and the US capital have a surprising (and suspicious) urban parallelism is known for some years. He discovered it before the pandemia a team of researchers from the University of Almería and the Polytechnic of Madrid. In his day the finding He had to speakbut it has now been, in 2025, when more interest has aroused. The reason? With Washington DC under the Informative focus International for Donald Trump’s policies, it has been the US administration itself that He has recognized publicly those similarities between its capital and Aranjuez. Click on the image to go to Tweet. “Two cities, the same plane.” As an advance to 250º Anniversary From the declaration of independence, which will be held next year, the US embassy in Madrid published a few days ago A tweet in which the parallelism between the Madrid town and the city bathed by the waters of the Potomac River stands out. “Washington DC shares its urban design with Aranjuez. Same 12 radio avenues, buildings disposal … even the meandro of the river. Two cities, the same plane”, claims The Madrid Embassy next to A link From the desqbre Foundation in which, once it is closed, a phrase can be read with a much more resounding tone: “The urbanism of Washington, a copy of Aranjuez’s.” A ‘Eureka’ moment. To understand it, it is necessary to go back a few years ago, when a member of the team composed of researchers at the University of Alicante and the Polytechnic visited Washington. There he realized a curious detail: the streets, the avenues, the disposition of the buildings, the walks … reminded him of another place that the Spanish urbanists know well, Aranjuez. Back to Spain he decided to delve into that heart and began an investigation that, years later, in January 2019, fruitful in An article Posted in academic magazine Urban Planning and Development. “Surprising similarities”. The title of that rehearsal It was a declaration of intentions: “similarities between the urban plan of L´enfant for Washington DC and the Royal Site of Aranjuez, Spain.” In their pages, experts remember that the influence of Versailles on the plane drawn up in 1791 by Pierre C. L´enfant For the development of Washington it is “well known”, but much less are “the surprising similarities” between the American capital and “the form Urbis of the Royal Site of Aranjuez. “The authors admit that these parallels can be” simple coincidences “, but at least” ask questions. “ The upper figure shows the plane of L’Enfant for Washington, DC (1791). The lower the plane of the Royal Site of Aranjuez de Domingo de Aguirre of the Army Geographic Center (1775). “It’s a copy of Aranjuez”. Much more resounding is The statement Posted on your day from the University of Almería to present the research. It points out that “Washington DC urbanism is a copy of Aranjuez.” “We discover, affirm and have managed to justify and publish that when the US capital is created, after the president George Washington, his design to Thomas Jefferson and this to the cartographer Pierre L´enfant, the city was based on the planes of Aranjuez,” ditch Francisco Manzano, one of the study authors. What are they based on? In the cartographic study of both city. Researchers have proven that the arrangement of the main buildings, radial avenues and the street system is similar in both places. The University cites a clear example: Washington DC and the Royal Site of Aranjuez have in common a peculiar urban feature, the “diagram of two large rectangular spaces” arranged in the form of ‘L’ and at whose ends are, analogously, two emblematic buildings are located. In the case of the American city, The Capitol and the White House. In the Madrid town, the Royal Palace and the Church of San Antonio. Do they have more in common? Yes. The identical position of these spaces in L with respect to the Potomac and Tajo rivers and the gutters that they start from. We also find correspondences between some Washington diagonal avenues with the Tagus Renaissance orchards walk system; Between the Plaza de la the Twelve Streets in Aranjuez and the 12 avenues that radiate from the Capitol “, Explain José Carlos de San Antonio Gómez, of the Polytechnic of Madrid. Another parallelism is left by the trident of the garden of the parterre in Aranjuez and the one formed in the original plane by Pennsylvania Avenue NW, Maryland Avenue Sw and Avenue H. “of the analysis of the plans of both cities and of the circumstances in which they were made, surprising parallels are inferred,” Underline The expert. Avenues and focal points of the Washington DC plans and the Royal Site of Aranjuez. Washington DC planes and the Royal Site of Aranjuez with the distribution of avenues. Looking for the causes. Detected the points in common between both places there was such or even more complicated mission: explain them. What are you due to? Could the Washington DC urbanists inspire in the planes of the Royal Aranjuez site? Spanish researchers also address those unknowns. The experts Remember that King Carlos III He sent copies from Aranjuez to Paris and the main European courts in the 1770 Pierre L´enfant. “There are no documents that prove to know him, but the evidence speaks for themselves,” they emphasize. There, in the Paris of the late eighteenth, … Read more

For years the chicken was the king of protein. Now the beans and lentils want to dethrone it

by

For decades they told us that the healthy thing was to change red meat by chicken or fish. The recommendation was so assumed that it became a kind of nutritional mantra. However, a change begins to glimpse either on supermarket shelves, gyms or social networks, the word “protein” appears more than ever. And the striking thing is that it is increasingly associated with meat, but plant foods. The question is inevitable: why now the vegetable protein? Vegetable protein in the center. The advisory committee of the United States food guides wants to turn the pyramid. According to a report by The Washington Postfor the first time it is proposed that vegetable proteins have priority. Not even chicken or fish, for years synonymous with healthy food, would occupy that place. Christopher Gardner, a professor at Stanford, summed it up with a simple phrase: “The beans, peas and lentils would lead the list of protein sources.” Red meat would be, on the other hand, in the last position. The evidence that supports this turn. The recommendation does not come from nothing. Rahman, clinical director of Barnard Medical Center, remembered the same media than those who eat more plants have less risk of cancer, diabetes, obesity and even deterioration of memory. In a study, Published in the American Journal of Clinical NutritionThey analyzed some 50,000 women, where they concluded that diets rich in plant proteins favor a healthier aging than those based on animal proteins. Beyond the guides, reality speaks for itself. According to The New York Timeslegumes are a pillar of the Mediterranean diet. A single cup of lentils or beans provides about 15 grams of protein, to which fiber, iron, magnesium, folate and vitamin E should be added. Vegetable or animal? Here the nuance appears. In Men’s Health They point to something that usually goes unnoticed In the middle of the vegetable boom: animal protein still plays with advantage. The reason is how we take advantage of it. Its essential amino acids – that our body cannot manufacture – are absorbed more effectively than those of plant origin. The simplest example is on the plate: 85 grams of chicken add up to 20 grams of protein. The same amount of chickpeas stays at six. Marie Spano, sports dietitian cited by the magazinewarns that those who follow exclusively vegetable diets need more daily total protein. Even so, the solution is to combine legumes, whole grains, nuts and seeds throughout the day. The great nuance: natural vs. ultraprocessed. Not all vegetable proteins are the same and here the most critical point appears. In The New York Times They warn of risk to trust ultra -processed that “disguise” healthy. A clinical trial showed that, even with good nutritional profile on the label, the ultra -processed (including shakes and vegetable meals) They do not offer the same benefits than minimally processed foods. In the study, the participants who followed a diet with little processed foods – fruits, natural yogurt, homemade legumes – lost twice as much weight and body fat that those who consumed “healthy” ultraprocesses such as vegetable lasagers ready to heat or protein smoothies. As the epidemiologist Filippa Juul summarized, cited by the NYT: “Ultraprocesses have less texture, chew faster and stimulate appetite artificially.” The world revolves around protein. The boom is not only nutritional, also cultural and commercial. We live in full “It was protein chic”: Protein has become a symbol of sculpted bodies and aspirational well -being. Social networks such as Tiktok popularize extreme routines, hyperproteic milkshakes and diets that touch the obsession, sometimes linked to eating disorders. The food industry has not been left behind. Product containers “High in protein” They adopt aggressive visual codes, with black and red typefaces designed to attract the male public. A strategy that remembers what happened in its day with the “Light” products in pink, aimed at women worried about weight loss. Protein is no longer just a nutrient: it is marketing, identity and business. So the powder protein? The most recognizable symbol of the protein boom may not be lentils or vegetable hamburgers, but the shake that is stirred in the locker room of any gym. But is it essential? The expert’s response is nuanced. Nutritionist Saray López defends it in Xataka As a practical tool: “It has no contraindications and can help reach daily requirements.” But others, such as the dietitian Jesús Guardiola, They underline this same medium that with a balanced diet it is not necessary to resort to supplements: “The problem is when the shake replaces real food.” Specialists agree that dust protein can be useful in concrete contexts: older people with difficulties in chewing, patients in recovery, who seek to gain muscle mass or even workers who barely have time to eat. But they insist that it is not a universal or magical solution. Everything indicates that it is not a passenger fashion. Protein has become the star of the global food conversation. From the official guides to the shelves of the supermarket, of the fitness routines to the homemade cooking recipes, everything seems to revolve around it. But beyond the boom, the background debate is not only how much protein we eat, but from what sources it comes and how it is processed.

Science explains why coriander knows you soap (and the fault belongs to your genes)

by

For many it is a touch of indispensable citrus freshness in tacos, guacamoles and curris. For others, it is a culinary abomination that It ruins any dish with a disgusting soap flavormetal or even insects. The coriander is undoubtedly one of the most polarizing herbs in the world, an ingredient that does not admit average terms and has generated much frustration. It is not a matter of taste. For years, science has investigated this phenomenon and the answer is clear: if the coriander knows you soap, it is not being a fussy: The fault, in large part, has your DNA. The “soap gene” exposed. The key piece of this genetic puzzle found it An association study at a genomic scale (GWAS) published in the magazine Flavour. Researchers analyzed the DNA of almost 30,000 people and found a direct connection between the perception of coriander soap and a specific genetic variant. The main suspect is a unique nucleotide polymorphism (SNP) known as RS72921001. This small change in the genetic code is found on chromosome 11, just in the middle of a group of olfactory receptor genes. And one of them, called OR6A2, is the perfect candidate to explain the mystery. Because? The OR6A2 gene encodes a receiver in our nose that is especially sensitive to aldehydeschemical compounds that are key components in the aroma of coriander. Interestingly, these same aldehydes are also a byproduct of the soap manufacturing process and are secreted by certain insects as a defense mechanism. In essence, people with this genetic variant have a kind of “antenna” superpotent for the aldehydes of the coriander. While a person without this variant perceives a fresh and herbal aroma, someone with the variable of the O6A2 gene receives an overwhelming sign that his brain interprets with the taste of soap. A more complex genetic cocktail. Although the O6A2 gene is the protagonist, the story does not end there. Another study conducted with twins by the Monell Chemical Sensa Center, and published in Chemical Sensaadd more nuances to the equation. This investigation not only confirmed that coriander aversion has a strong hereditary component – stating the inheritability of taste for coriander in 52% – but also identified other genes involved. Specifically, there have been three genes that have identified in this genetic combo. The first one is TRPA1 which is known for detecting spicy substances, the second is GNAT3 which is crucial for the transduction of signs of taste in the language. The last is the TAS2R50 That is a receptor of bitter taste. This suggests that, for some people, the rejection of coriander is not only due to a soap smell, but to a complete sensory experience that may include bitter notes and a sense of unpleasant itching or flavor. The geography of flavor. Genetics is closely linked to offspring, and coriander aversion is no exception. Statistics demonstrate a fascinating global division, as revealed by a study by the University of Toronto. The prevalence of coriander aversion change dramatically between different ethnocultural groupsaccording to these proportions: Oriental Asians: 21% Caucasics: 17% Afro -descendants: 14% South Asians: 7% Hispanics: 4% Middle East: 3% These percentages make a lot of sense. These data are not casual. Populations with less aversion are those in whose kitchensh It has been a pillar for centuries, such as Mexican, India, Thai or the Middle East. This raises an interesting evolutionary question: was the kitchen of these regions adapted to a population that genetically enjoyed coriander, or constant exposure for generations helped overcome an initial aversion? The answer is probably a mixture of both. How to learn to love coriander. While your DNA predisposes you to hate the coriander, it is not necessarily a judgment of life. Inheritability, although significant, is not 100%, which means that environmental factors and exposure play an important role. Experts suggest that it is possible to “train” the brain to accept, and even enjoy the coriander. Some of the tricks they give is to crust the coriander in the form of pesto or sauce so that the soapy aldehydes are diluted. But you can also bet on introducing it little by little and mixing it with other powerful flavors so that the palate can get used to it. Images | Lindsay Moe In Xataka | We have finally discovered the sixth flavor. The only problem is that if you are not a fly you will not be able to enjoy it

Your grandmother was right with Kiwi, and now science has given her marketing a powerful weapon

by

It is a milestone for European regulation: for the first time, a fresh fruit, the green kiwi, has made the European Commission authorize you A “specific health declaration”. What your grandmother told you now comes with an official stamp and scientific support. But this also gives rise to a Great marketing network. A victory for brands. This news, which at first glance seems a victory for science and consumers, is actually a fascinating case study on how food industry, marketing and European regulation that has more recesses than it seems. The application, driven by the neozygous giant Zespri, has taken seven years to see the light and, although it celebrates a real benefit, reopens the debate on what we consider “healthy” how we sell us. A cooked health statement for years. So that A food can carry a slogan related to healththe inventiveness of a marketing team is not enough. As the Food Technologist explainsMiguel Lurueña in the country, for almost two decades the European Union demands a rigorous process to avoid misleading advertising. The first request for the Kiwi to have its recognition started in 2018 when Zespri, the world’s largest kiwis marketer, submitted a request to the European Commission claiming that the Kiwi contributes to the maintenance of normal defecation. To support him, he contributed 19 scientific studies. It is not something two days. The scientific verdict did not reach 2021, when the European Food Security Authority (EFSA) comes into play. His work is to review scientific evidence and determine if it is solid enough to give your approval. Something that arrived three years after the initial application. The next step was the politician, where the Member States of the European Union had to agree on a statement on this food and its properties. Because obviously it is something that will directly affect their citizens. A text with a small print. The official text approved is: “The consumption of green Kiwi contributes to the normal functioning of the intestine by increasing the frequency of the strokes. “The law allows simplifying it, so get ready to see ads with a clear and direct:” Help to go to the bathroom. “ But the statement will only be able to use for fresh green kiwis of the variety Hayward And the consumer should be informed that the effect is achieved with a daily intake of 200 grams of pulp, which is equivalent to about two kiwis of good size. The kiwi’s “superpower” is not so exclusive. This is where history becomes very interesting. Zespri argued that the kiwi effect was due to a unique combination of factors: its fiber, an enzyme called Actinidinephenolic compounds and other substances that They altered intestinal motility and the Microbiota. It seemed that the Kiwi had a secret formula. However, EFSA itself in its scientific opinion reaches a much less exclusive conclusion: evidence does not demonstrate that the effect of green Kiwi on defecation is higher than the one that could be expected because of its dietary fiber content. Figures can be put. Keep in mind that 200 grams of Kiwi provide approximately six grams of fiber. This is the amount that, according to studies, produces the beneficial effect. But that amount is not, much less, exclusive to Kiwi. We can get a similar fiber contribution in other foods that are often much cheaper. For example: A cup of cooked lentils (about 180 g) contains more than 15 grams of fiber. A ration of raspberries (125 g) provides about 8 grams of fiber. A comprehensive pasta dish (80 g dry) is around 7 grams of fiber. Two medium pears also add up to 6 grams of fiber. In this way we see that the Kiwi can work and is very healthy. But the approved benefit is not a ‘magical’ property, but the result of its fiber content, which is a nutrient present in many other foods. In your skin is where its benefits lies. Although a priori it may seem necessary to peel the entire fruit, including kiwis, Science tells us something different. In past studies it was made clear that Kiwi on your skin contains a fiber rich fountain and vitamin E, although it is recommended to wash it well before consumption. The same occurs in other types of fruits, where much of the fiber is also found in the shell that is in essence is viscous fiber. A guy that helps reduce appetite when gastric emptying and stimulating hormones that They promote satiety. The door open to advertising picaresque. The Kiwi case feels a precedent, but also reminds us of the strategies that the industry has been using for years. Regularization allows a product to contain a significant amount of a nutrient with an already approved health statement such as vitamin D, can use a slogan to promote it. He Most famous example is Actimel’s. Danone did not get the EFSA to approve specific statements for bacteria L. Casei. The solution? Enrich the product with vitamins D and B6, for which the declaration “contributes to the normal functioning of the immune system” is authorized. From there, to the famous slogan “help your defenses” there is a very short step and, above all, legal. Valuing food by a nutrient. This strategy that we have seen in the food industry leads us directly to the tendency to value food by a single function. In the case of Actimel only for its function for the immune system and now the Kiwi to go to the bathroom. In this way, a food is not valued in conjunction with all its nutrients. Eating two kiwis a day can help with constipation, but it will not serve as “antidote” if the rest of our diet is based on poor ultraprocesses in fiber. The great forgotten: the nutritional profiles. To prevent an industrial bun and saturated fats from being advertised as an iron source that helps diminish, simply because it is enriched, European legislation foresaw in 2006 The creation of … Read more

I have measured the CO2 of my office for weeks. And now religiously vento every hour and a half

by

I’ve spent a few weeks trying The Netatmo Meteorological Station In my office, a ten -square -meter cubicle where the workday passed. August in Valencia is brutal: 35 degrees and 75% moisture at noon are normal values. But what I really wanted to verify was not the temperature or moisture. It was the CO2 concentration. The first Monday I started curious. At 8:05 a.m., with an open window and door since Friday, the sensor marked 438 ppm, atmospheric level. I started working. At 9:30 a.m., 455 ppm, minimum increase. Then I closed door and window to simulate winter conditions. Effects of CO2 concentration on the environment. Image: Vobu. At thirty minutes: 802 ppm. An hour later: almost 1,400 ppm. A little later: more than 1,600 ppm. Had already begun to notice That characteristic mental fatigue, that heaviness That a few days blame for fatigue. That inability to do well what you usually do well, mixed with apathy. It is not placebo, there are plenty of studies that support it. As Este de Harvard and Syracuse of 2015: The levels between 1,000 and 2,500 ppm – manner in offices – reduce up to 15% the yield in complex cognitive tasks. In decision -making, Hasdta 23%. I opened the window but not the door. The CO2 dropped from 1,600 to 800 ppm in 25 minutes. The next day, with cross current: same descent in 12 minutes. Half. A difference that did not expect so marked. In a short time, the level returned to 450 ppm. Graph of the Netatmo application during one of the tests: all night with the empty office, beginning of the morning working with everything open. I closed door and window. And when I reached the peak of almost 1,600 ppm, I opened back and window. And the fall was even faster than the climb. Image: Xataka. This shows the Netatmo app interface the CO2 concentration, visually indicating its condition, along with other values. Image: Xataka. Another test. Only opening door or window, the fall is slower than if we open both to create a current. Something we know always, but now we can quantify and assume with greater awareness. Image: Xataka. Netatmo has an error margin of ± 100 ppm up to 1,000 ppm, ± 10% above. It is not laboratory precision, but to understand your home it serves. The important thing is not the exact number but the evolution and its correlation with how you feel. With the passing of the days, varying openings and closures, I began to detect patterns. Ventilating more frequently than usual, sporadic apathy and mental mist. They are directly correlated with air renewal. Which takes me to the next point: The air conditioning. I sensed that I would not improve the concentration of CO2. Indeed: the air moves and cools, but does not renew it. Purifiers would not help except that they have outdoor entrance. They filter particles, do not eliminate gases such as carbon dioxide. When looking at the graph in more detail it is easy to see that by a lot of ventilation and current that there is, a human breathing inevitably increases the concentration of CO2 in the stay, and in a cumulative way. Although within the appropriate values. Around 6:00 h entered a few minutes (climb), I left shortly (low) and then returned to spend the whole morning (go up) until I went to eat (low). As if he had a presence detector. Image: Xataka. Image: Xataka. I brought the netatm to bedroom. Two people sleeping with a closed window and open door: CO2 rose from 450 to 1,100 ppm. Heavy awakening, feeling of not having rested. Next night with open window: maximum 640 ppm. I woke up remarkably clearer. He has convinced me to sleep with open window even in winter. The station measures more: interior/exterior temperature (with the separate module), humidity, barometric pressure, noise. It is expandable with pluviometer and anemometer. Elegant app, indefinite historical, integration Homekit flawless. But living vertically and without garden, for me the real value is in CO2. On the integration with homekit: when CO2 went from 1,100 ppm, this notification reached me in Mac (image) and iPhone. Image: Xataka. And notification on the iPhone. Image: Xataka. I have learned that working with more than 1,000 ppm is to function at 70% cognitive. The problem: do not notice immediately. Like that second cup that you think harmless until you try to add the head account. Now a lot more. Permanently open windows or, when time prevents it, more frequent openings than before. Do you justify 110 euros This learning? If you work in closed spaces, yes. Not for the apparatus, but for the consciousness it generates. He used to ventilate when “noticed the loaded atmosphere.” Now I know that when I notice, I’ve been working badly for an hour. It is the difference between driving with velocimeter or eye. The paradoxical thing is that after three weeks, Netatmo has taught me not to need it. My body has internalized the times and signs. I recognize that very slight ocular heaviness, that subtle friction in words flow. But Without the sensor’s objective data, I would never have developed this sensitivity. It’s like learning to refine an instrument: you first need the fingerboard, then your ear learn to recognize dissonance on its own.

The one with the brain chips

by

The Chinese government loves to plan. Since the fifties they use a system called “Quinquenal Plan” in which they establish their objectives and the steps to achieve them in a period of five years. They also have other long -term plans, such as “Made in China 2025” in which 13 strategic technologies set out to lead (With very good results, by the way). Now China has proposed to lead a new technology, BCI (Brain Computer Interface) devices. Five years. It is the margin that the Chinese government has been put to create a brain-routine interface industry that is internationally competitive. The road map states that by 2027 they get significant advances and that in 2030 they have a solid industrial ecosystem, with two or three leading companies worldwide. Government support. To promote the creation of this new industry, the Government will encourage investment in the sector and offer a favorable policy when approved key products such as medical implants. They also consider creating industrial parks specialized in BCI, so that companies work together and collaborate with each other. Competence. Neuralink, founded by Elon Musk, is the best known company in this sector that has already achieved Place brain implants in humansalthough the Australian company Synchron takes advantage By achieving more brain implants with less invasive techniques. In the United States also highlight Blackrock Neurotech and Paradromics, more focused on research and medical applications respectively. Chinese companies. Although not as advanced as in other countries, China already has several companies dedicated to this industry. As They count on Wiredone of them is Neucyber Neurotech, a start-up that arises from the Chinese Institute for Brain Research and has already placed its Beinao-1 implant in five paralyzed patients. Participants are now able to move a cursor and navigate between different apps. They have also done it with a semi-invasive method that places the implant in the outer layer of the brain, greatly reducing the surgical risk. Neuroxess is another of the companies that is achieving significant advances. In their case they have placed their implant in six patients with paralysis; Three could control devices and with the other three they managed to accurately decode the Chinese language. And of course Brainco, one of the “Six Little Dragons” by Hangzhou which was founded in the United States, but moved to China after government incentives. In this case they are centered on prostheses such as This hand that is controlled with the brain And their advantage is that they are pioneers in mass production and offer products to the consumer market. A different approach. While the Neuralink approach is more radical, both for using invasive methods and for its idea of ​​implanting chips to everyone, China’s plan opts for a more specific bet for health applications. In addition, semi-invasive techniques such as Neucyber Neurotech want to focus and promote non-invasive BCI devices such as Brainco to conquer the mass market (not everyone will want to implant a chip in the head). Use cases. The document mentions “Wearable” BCI products such as helmets or glasses that could be used in different areas. A case of use would be the prevention of traffic accidents alerting in case of drowsiness or lack of attention. Also in industries where they work in conditions or with hazardous materials, alerting low levels of oxygen, preventing poisoning or fainting. In Xataka | China was the world’s landfill, today its problem is another: it does not have enough garbage to burn
