A garbage cube of 2,000 ago in Mallorca exposes the star product of Roman fast food: Zorzal’s skewer

by

The concept of “fast food“It is currently strongly associated with that of”junk food”. It usually involves a not very healthy dish due to the presence of processed foods. But fast food really exists For centuries And the Romans, of course, have something to say there. And a recent study puts on the table an important fast food industry in Roman times to northern Mallorca. The star dish? Singing birds. “Popina”Alejandro Valenzuela is a researcher at the Mediterranean Institute of Advanced Studies in Mallorca and the author of a Published article in the International Journal of Osteoarchaeology in which he details how in the Roman city of Pollentiahe Zorzal He was the protagonist of street food. Founded in the 123 AC to the north of Mallorca, Pollentia was an imperial city for the empire due to its location in the Mediterranean and its ports that They favored trade With the island. Today is an archaeological site in which we have a curious and small theater, but in its day it must have been a very busy city, a bustling shopping center in which food played an essential role. Inside the shops, were the ‘Popinae‘. These are small establishments where you could eat something fast and have a wine before following the way. They were focused on the lowest classes of Roman society. Searching in the garbage. This was something common in Roman cities due to their rhythm of life. In Herculano and Pompeii you can see some ruins in good condition of Themopoliumwhich are more like taverns for somewhat more wealthy people, but basically, in both cases there was a bar with amphorae to get some hot food, serve the client and that it followed on their way. An example of Thermopolium Valenzuela, what interested him was to know what was in those mud vessels, but to discover what the inhabitants who were walking for Pollentia had to look in their garbage. Near one of those popinas there was a septic tank of a few meters deep in which everything was thrown. Part of the garbage was ceramic, which has allowed to date the date of use of the well between 10 AC and 30 AD What else was there? A large number of mammalian bones, birds and fish. And the bones of the birds are the ones that caught their attention. Pollentia location in Mallorca in image A. in B, the location of the well. In C, the meters at which a greater concentration of bones were found Fast Food Bird. Although there were several species, such as chicken, the bones were mostly slut. They are small singing birds associated with the diet of the upper classes of the Roman empirebut here we are in a very different context: popular food at street level. The remains highlighted the skulls and sternons of those birds, which indicated one thing: the most juicy parts should be the ones that served in the popina. As with other birds, the extremities and the upper part of the chest are the most juicy, and Valenzuela estimates that removing that juicy meat allowed the food seller to cook those parts quickly to the grill or in oil to serve it quickly. It is a meat that hardly takes a few seconds to cook. The darker, the more presence of parts they found in the black well. Within the red perimeter, the most fleshy parts and their associated bones, little present in the well Seasonal. There is also the possibility that customers sit down and consume the zorzal in dishes, since ceramic remains could indicate that there was a dishes, but due to the size of the bite, Alejandro Comment In Live Science that, within the “context of street food, it is also plausible to serve in skewer to facilitate consumption.” In the end, except exceptions, food in ancient times was linked to seasons and the foal is a seasonal product that would have integrated well into a diet like that of Roman cities with others like domestic chicken either European rabbittwo species whose remains would also have served in this restaurant Fast food of Pollentia. But the most important thing is that this finding makes the belief that the Zorzal was a luxury bite for the Romans staggers because the Popinae They were not precisely the premises that most frequented the High classes.

Not for pleasure, but because the intestine has memory

by

A year ago, every time I ate something, my belly swelled like a balloon. I felt heavy, with gases, uncomfortable. I did not understand what happened to me, until I tested positive for bacterial overgrowth in the small intestine or its short version, Sibo. I started an antibiotic treatment and a very restrictive diet. I left gluten, dairy, nuts, fruits … almost everything. And when it seemed that I finally felt better, the strangest part of the process came: I had to reintroduce some foods, little by little, as if it were a vaccine; but I did, I would become intolerant. Increasingly widespread. Increasingly widespread. In both medical consultations and conversations, surely the term Sibo (for its acronym in English, bacterial intestinal overgrowth) is no longer unknown. This condition describes an imbalance in the intestinal microbiota: bacteria that should be found in the colon end proliferating in the small intestine, an environment where they should normally be almost non -existent. This invasion causes varied and annoying symptoms, such as abdominal swelling, gases, pain, diarrhea or constipation, According to Mayo Clinic. It is estimated that up to 15% of the Spanish population suffers from it, and is more frequent in women between 30 and 50 years, According to the Spanish Society of Primary Care Physicians (Semergen). Its diagnosis has increased in recent years thanks to greater awareness and evidence such as the breath test, a non -invasive technique that measures the amount of gases produced by bacteria after ingesting carbohydrates. After diagnosis. It is followed by a low diet in Fodmaps, a protocol that eliminates the most fermentable foods to relieve symptoms. It is not a cure in itself, but it helps reduce gas production and abdominal discomfort while antibiotic treatment takes effect. The problem comes later. We talk to Jesús Guardioladietitian-nutritionist, to understand what happens in that critical phase: food reintroduction. “A low diet in Fodmaps should not be maintained in time because, when restricting so much, it can affect nutritional diversity and microbiota. But also, if you stop consuming certain foods for a long time, you can lose tolerance to them,” he explains. The intestine also forgets. Stop eating gluten does not cause celiacy. This is an autoimmune disease that only appears in genetically predisposed people. However, eliminating it prolonged can generate an unexpected reaction: that the body tole it worse when reintroducing it, Guardiola points out. This can go through several mechanisms: enzymatic (the body stops producing enzymes such as lactase, necessary to digest lactose), immunological (less exposure can alter the immune response), or by changes in the microbiota (bacteria in charge of digesting that food disappear). From Monash Universityin Australia, an institution that developed the diet has explained about these effects in prolonged restrictions can reduce functional tolerance and affect microbial diversity. But not a real intolerance. No, of course. The point is that it has been shown that eliminating food groups can alter microbiota and digestive capacity. The body needs gradual exposure to adapt, so the reintroduction must be done carefully and individually, According to the academic institution. “The key is to do it little by little, evaluating the symptoms, writing amounts and reactions. If you introduce many foods at the same time and something feels bad, you will not know what it was. And if you do it too fast, it is more likely that you can fall or that you suggest you thinking that it will sit badly,” Guardiola warns. The diagnosis of Sibo. The boom has also been accompanied by some controversy. Each time it is diagnosed more frequently, but not always with clear criteria: in many cases it is by discard, when other pathologies have been eliminated, and sometimes without conclusive evidence. This complicates the precise identification of the disorder, and can lead to confuse with food intolerances, functional disorders or, simply, with bad habits. From Semergen They have insisted that the treatment requires a comprehensive approach: not only medications, but also changes in the diet, lifestyle and analysis of the full medical history. To this is added an increasingly common problem: patients who adopt low fodmap diets on their own, without professional supervision, and who keep them for months or even years. Instead of improving, this can end up deteriorating even more intestinal health. What I learned during the process. Today I eat gluten again. I am not celiac. But I went through months of fear of food, not knowing if what I ate was healing or getting sick. I understood that there are no good or bad foods, but contexts, quantities and, above all, processes. Reintroduction is not just another part of treatment. It is a way to reconcile with food. And to understand that, sometimes, the problem was not bread, but how we stopped eating it. Sometimes healing means exposing yourself to what you thought you hurt you. In my case, yes: I had to inoculate gluten.

After the giant wolf, a huge bird of New Zealand wins points to be desixtinquida. And Peter Jackson has a lot to do

by

‘Jurassic Park‘It is a science fiction story until it ceases to be. Not so much because there are those who consider current technology can bring dinosaurs backbut because there is already a company that is returning to life species that were extinguished thousands of years ago. It is colossal and are accepting requests to relive your favorite extinct animal. Whenever you call yourself Peter Jackson and have 25 million dollars to donate them. “Hobby”Jackson does not need presentations at this point. After several minor films, he jumped to world fame with his adaptation of ‘The Lord of the Rings‘, which allowed him to fulfill another of his dreams: roll a King Kong movie. In the tape the love that the New Zealander director feels for animals from other times, but that passion transcends to the screen was felt. Interestingly, one of the director’s fun is to collect Moa bones, to the point of having one of the largest private collections in the world focused on the bones of that extinct animal. “The movies are my work, but the moa are my hobby,” commented Jackson. From left to right a kiwi, an ostrich and a moa. They were … big De -sextinging the moa. But … what is a moa? In a nutshell, it’s like a kiwi, but about three meters high, about 250 kilos and can not fly either. His closest living relatives would be the aforementioned kiwis, but also the casuaries and the most similar would be Emú. New Zealand natives, the MOA was not extinguished: we extinguish it. When the Maori arrived at the islands, they began to hunt them and, although sightings have been reported in the nineteenth century, there is no evidence of this and it is considered that the MOA was extinguished, at least 500 years ago. Jackson comments that “any Neozyre child feels fascination with Moa.” Colossal comes into play. The filmmaker has between 300 and 400 Moa bones, and it will be that private collection the one that drives The animal’s de -sexyction thanks to a company called Colossal. It is not the first time we talk about them, since it is a company dedicated to biotechnology that has become popular for their interest in Return animal to life like mammoth or the Tasmania tiger. Also to Dodo. What they do is Take extinct animal DNAsomething that can be done from bones such as those that Jackson possesses and, the more remains, the better, and combine it with samples of relatives who live today. That is the easy thing: the complicated thing comes when, once the genetic information of the two DNA is combined, they are “filtering variants” to edit the genes and get exactly the animal they want. Finally, a living animal is used to give birth to the “new” creature. And it is not cheap. Money. A lot. In a recent financing round, Colossal Biosciences reached a assessment of 10,200 million dollars. At the end of 2024, Jackson already He collaborated With 10 million dollars in Colossal Bioscience, but now it has donated another 15 million for the company to place the MOA in its list of ‘goals’. This implies that we will take time to see the result. Now, Colossal is not just castles in the air. In April of this year, the company advertisement His first success: they had achieved resurrect the giant wolf, the Aenocyon Dirus. Now there are three puppies called Romulo, Remo and Khaleesi that, with six months of age – they were born in January this year – they have reached a weight of about 36 kilos and a length of 120 cm. They are expected to reach 180 cm and 68 kilos each. Jackson on the left and Ben Lamm, one of the founders of Colossal, on the right. Both with moa bones Complex. We will see what happens to the moa, but there are those who think that what is best colossal is Sell the motorcycle. With the MOA we are at a very early stage of the welcoming, but as we read in Physthe process seems to be more complex than with the wolves. Beth Shapiro is the chief scientist of Colossal and has commented that, unlike what happens with mammals, bird embryos develop inside eggs, so the process of transferring an embryo to a substitute mother will be very different from in vitro fertilization in mammals. Nic Rawlence is a paleontologist who works at the University of Otago and has commented that reviving New Zealand birds “is not scientifically possible with current technology.” The problem is that there is no good moa genome and its closest relatives are the Tinamúesof those who separated 60 million years ago. Criticism Apart from that, which is an important challenge, there is another issue: if an extinct animal is revived, is the patent of nature or the responsible company? Ben Lamm, the director of Colossal, has already explained that They do not want to monetize those animals directly, but sell its technology. But of course, he does not close the door to patent what they wish. And, although Alex, 10 would love to see a tyrannosaur in the streets of San Diego, the current Alex knows that no company is going to do it for love of art and that, probably, it does not matter that the habitat of that animal does not look like it or the least to the one he had at the time of his disappearance. Who is excited It’s Jackson. “Returning the moa to life would be so exciting, if not more, than any movie you could do.” Images | Colossal, Kkpcw, Gage Skidmore In Xataka | We just closed a primate.

Let’s tell you what are The best alternatives to Google Driveso that if you want to leave the Google cloud storage service you know of other similar services. We are going to tell you everything, from other similar suites also with office tools to other services only for the cloud. In each of the services we mention we will give you a description, Let’s tell you prices. Almost all offer free versions, although with amounts of anecdotal storage. In addition, keep in mind that we have based on services with our own cloud, not those that serve to self -bealo the cloud. And as we always say in Xataka Basics, if you think we have left some service that you think should be on the list, we invite you to Tell us your suggestions in the comments section. Thus, all readers can benefit from the knowledge of our xatakers. Dropbox It was one of the first cloud storage services to arrive, and years later and after the emergence of large companies such as Google and Apple, it is still one of the great references. It has good integrations, and you can install it in almost all desktop and mobile operating systems, in addition to complying with the main safety standards. Although end -to -end encryption is not for less expensive subscriptions. The big problem of this platform has always been that offers very little free spacejust 2 GB being able to use it on three devices. Then you have several payment options, ranging from 12 euros per month for 12 TB to 21 for 15 TB to share among several users. Internxt A Spanish cloud storage service, with the data housed in Europe and open source. Recently they have initiated a restructuring process, abandoning secondary projects such as photo apps, and have begun to focus only on their pure storage apps. In the past they have had a problem, but personally I have been encrypted from end to end for several months, and in addition to monthly subscriptions of 2 and 4 euros per month for 1 or 3 TB, you can buy storage with unique life payments. In addition, it includes services such as VPN, antivirus and more. Icloud Apple’s cloud storage platform, although it is not so versatile by not having Android application, although for Windows. Even so, It is the main alternative for Apple devices userssince it integrates perfectly in all of them. In its free version, ICloud offers only 5 GB of storage, and automatic synchronization on devices. Then you can pay from 1 euro to month for 50 GB to 10 for 2 TB, and there are even higher rates. Payment plans also have functions as a private relay, hide your email when registered, and so on. OneDrive OneDrive is the cloud storage service, and right now It is included in the Microsoft 365 subscriptionso in addition to the cloud you also have Word, Excel or PowerPoint. This places it as a direct Google Drive competitor, especially in terms of added services. OneDrive have applications for iOS, Android, Windows and Macos, and A free plan with 5 GB of storage In the cloud. It is not much, but for 2 euros a month you have 100 GB, for 10 you have 1 TB, and then you can go up. Pcloud With servers housed in Europethis Swiss company has a large amount of prices, with native applications for Windows, Macos, Linux, Android or iOS, in addition to extensions for browsers. It has prices ranging from 5 and 10 euros per month for 500 GB and 2 TB of storage, to plans of life paymentwith a unique payment to have your storage forever and without quotas. Proton drive Proton is a Swiss company that offers an amount of services, including one of cloud storage. It is much more expensive than the averagealthough focusing on privacy, and includes online documents editor. It offers only 5 GB for free, and in its payment plans you have 200 GB for 5 euros or 500 GB for 13 euros. The Tera costs 20 euros, although there is a 40% discount if you pay annually. MEGA Mega was created by the creator of Megaupload several years ago, and it has been possible to place as a great reference for cloud storage and file sharing. In addition to cloud space, its payment subscriptions include a VPN and a password manager. In its free mega modality it gives you 20 GB of storage with unlimited transfers. Then you have pro versions with prices of 10 euros for 3 TB or 20 euros for 10 TB, something less in each if you pay annually. In general, is a bit cheaper than other alternatives, offering a little more space. NordLocker NordvPN managers also have their own cloud storage service. It is private, encrypted and safeOr, with applications for Windows, Macos, IOS or Android, although you can also access from any browser. This service is optimized for the safety and privacy of your files, with a good end -to -end encryption. This service offers a free account with only 3 GB of storage, but you also have 500 GB for $ 8 per month or 2 TB for $ 20. Prices are reduced to less than half When you hire an annual plan, where 2 TB leave for $ 7 a month. Box Another platform that has been available for a long time, although it is a bit more code than other alternatives. Its free subscription offers 10 GB, but with a load limit of 250 MB maximum per file, while for 12 euros per month you only have 100 GB. However, it is a versatile platform with many integrations with third -party services, and that has applications for almost all platforms.

The US already has the first salmon cultivated in the laboratory. It is a relief for wipes who ask for the time

by

The world is hungry for fish, but goes through areas. In Spain, Consumption is downhillso much that fishmongers want to reinvent themselves to serve our pets Before us. In other countries, such as China, That hunger is voraciousto the point that your folders They have been small And they are Going for those of Latin America. To avoid folding, there are those who investigate “alternative proteins”, And in the United States they have already developed the first salmon cultivated in the laboratory that is served in a restaurant. And with a series of advantages that does not really have salmon. Fish hunger. The forecasts They point out that the global aquatic food consumption will double by 2050 compared to the 2015 levels. That will imply that it will go from about 80 million tons annually to almost 155 million tons. The problem is that production must follow the rhythm. It is something promoted by population growth, the improvement of quality of life in certain countries and the development of aquaculture. As we say, China has a role in this story because it is not only the largest world consumer of fish, but it is also creating huge ships to raise new fish. And in Africa also An increase in demand is being seen. According to the FAOto maintain consumption until 2050, total production should increase by 22%, and is a capital challenge. That’s where the laboratory alternative becomes interesting. Cultivating salmon. Wildtype It is a company that has attracted to investors Like Jeff Bezos, Mandamás de Amazon, but also actors such as Leonardo DiCaprio or Robert Downey JR. Currently, they operate a factory in San Francisco and have just launched the ‘Saku’. This is cultivated salmon that is designed to eat when Sashimi stylewith a texture, flavor and ‘freshness’ comparable to really salmon. Here the key is to know how this salmon has been cultivated (it becomes weird to speak in those terms of a fish). The researchers extracted real salmon cells, specifically from salmon coho in their fry stage. In BIORREACTORS And using a patented “nutrient mixture”, cultivate those cells, combining the resulting cell mass with vegetable ingredients to replicate both the texture and the taste of traditional salmon. As they expose in The Washington Posta salmon can take about two years to mature, but in two weeks a 220 grams “fish” block can be created with the Wildtype method. And claim that it has a nutritional and omega-3 profile similar to that of wild salmon. One from Saku “NO OBJECTION”. And what do agencies that decide what enters, and what not, in circulation in the United States think? Well, they have no objections. ” Each country or region has a health entity that is the one that establishes a regulation that allows certain substances and products to be present in what we eat. They do not always agree, but if a product wants to enter a market, it must pass under the magnifying glass of that body. In the case of the United States, it is the FDA (Food and Medicines Administration of the United States) that, at the end of May, He gave permission to Wilkdtype so that your cultivated salmon is marketed. With that success, the cultivated salmon has already debuted in Kanna famous Haitian restaurant located in Portland, but it is expected that little by little it will arrive at more restaurants and shops in the form of ‘false’ packaging. Looking at the advantages. As with the coffee without coffeesalmon without salmon will allow maintaining the production of a very consumed food, but without continuing to measure in some wipes that agonize. But as important as sustainability, reduction of overfishing and habitat destruction which implies, is the issue of food security. This ‘Saku’ occurs in a production environment controlling, which minimizes exposure to pollutants, parasites and something that, unfortunately, is present in practically everything we eat, but above all the food from the sea: The microplastics. And another from Saku And the fishermen? When something that replaces something already established, the first question that comes to mind is what will happen to what moves to give way to the new. We have seen it from the Industrial Revolution, with AI and to Wimbledon with the Line judges being replaced by a computer. And, in this case, the question is whether something like this seeks to replace fishermen. Justin Kolceck is the co -founder of Wildtype and, in this article of the Washington Post, he comments that they do not seek to put fishermen outside the business or “eliminate the need for aquaculture. The amount of fish consumed is booming and the projections are so high that we will really need all the production we are doingin addition to the traditional and some more help in the world of plants to meet demand. For my part, I only have to add that in some Spanish supermarkets there is already salmon based on plants and oil and, although it reminds the taste of the animal, the texture does not look like. Maybe that Saku is the answer … Image | Lou Stejskal In Xataka | Until the 90s nobody in Japan ate sushi with raw salmon. Until a marketing campaign changed everything

Japan destroys the data transmission record again with 1.02 petabits per second. The impressive has been the distance

by

Japan has established A new record World Cup in data transmission per fiber optic, sending information to 1.02 Petabits per second through 1,808 kilometers away. The achievement, achieved by a joint team of Electric Industries Summit and the National Institute of Information and Communication Technologies (NICT) From Japan, it marks a new milestone in long -distance optical communications. And best of all: it has been achieved with fiber optics compatible with any device. The key technological jump. The advance does not reside solely in speed, but in the distance traveled maintaining a standard cable diameter. The previous records in speed Pure had reached 1.7 Petabits per second, but only covered 63.7 kilometers. This new brand multiplies by 28 the distance without increasing the thickness of the cable, bringing technology to real commercial applications. Image: Ispreview How it works. The system uses an optical fiber of 19 nuclei integrated in a cable with standard coating diameter of 0.125 millimeters, the same as the current fibers. Instead of a single beam of light, the fiber transports 19 parallel signals taking advantage of both the C and L bands of the optical spectrum. Electric Sumitomo optimized the structure and disposition of the nuclei to minimize losses, while NICT developed amplifiers capable of simultaneously enhancing the signals of all nuclei. Dimension of achievement. To contextualize the magnitude: 1 Petabit is equivalent to 1,000 terabits or 1 million gigabits per second. Compared to The average broadband speed in Spain (which is usually around 250 Mbps), this record is approximately 4 million times faster. At this theoretically, 10 million 8K video channels could be transmitted simultaneously. Or download the entire Netflix library in seconds. Practical implications. The record establishes a new standard within the framework of “capacity-duty” (1.86 exabits per second-kilometer) using standard diameter fiber. This means that future networks could exponentially multiply their ability without changing the existing physical infrastructure. Intercontinental submarine cableslike those that connect Europe with America, they could benefit from this technology, although at greater distances (more than 5,000 kilometers) the speeds would be lower but still impressive. The way to commercialization. Although these advances will not immediately reach domestic connections, they do mark the future of long -distance communications. The team now works on improving the efficiency of amplifiers and signal processing to bring technology closer to its real implementation. Global Internet traffic grows, but it’s nice to know that the optical fiber and the form of the cables we use today, they are still enough to evolve in this field.

What would football be adapted by sex

by

If something is demonstrating the Eurocup 2025 is that women’s football has more and more followers, something that has already been seen in the World Cup of 2023. The ‘king sport’ in its female version shakes stigmas, raises passions and feels thousands of people before the TV to follow the matches that are played in Switzerland; But also does something else: reopen old debatessuch as whether men and women should play with different norms and fields, adapted to their physical conditions. A study has just suggested that debate with new data. What happened? Than in full Women’s Eurocup The public company of Swiss broadcasting, SRF, has just published A study that the melon of the melons of football reopens: Should women and men compete in different fields, adapted to their different physical abilities? If a Spanish male (and the calculation is transferable to other nationalities) measures on average 14 centimeters and weighs 16.7 kilos more than its countrymen and those factors influence aspects such as The jumps either The speedWould you have to adapt the game conditions per sex? METER AND KILOS QUESTION. The study SRF starts from an interesting premise: if we accept that women should perform more physically than men when playing in the same fields, how relevant is that extra effort? What would he mean for a male? The Swiss chain responds to both issues with a theoretical exercise: it has imagined what a pitch would be like if the men meet the level of demand that their companions now assume. Their conclusions are fascinating and affect such basic issues as the balls. FIFA establishes that the regulatory balls must have a minimum weight of 410 grams and not exceed 450. As for the size, the circumference has to be between 68 and 70 cm. SRF’s study suggests that for men to play “under the same conditions” that women their balls should be much larger, with a circumference of 76 cm. “It would be the same size and weight as a basketball”, duck. And that is the first of many adaptations. Gatestroads, fields and XXL areas. The report is based on the work of researchers from the University of Trondheim and answer some curious questions. For example, how great they would have to be The goals so that men face the same conditions as women? Starting from the base that on average players are higher than the players, the study concludes that their goals should be 0.55 m longer and 0.13 higher. “An adequate goal would measure 8.4 m wide and 2.72 m high. Even a 1.9 m goalkeeper would have few possibilities for precise shots,” he concludes. The same logic moves to the pitch. Right now the fields suitable for international competitions must move between 100-110 meters long and 64-75 wide, although the standard measurement of the majority of first fields is 105×68 m. “For a clean play in male football, the field would have to be bigger,” collect SRF: “20% larger: 132×84 m”. More kilometers. The players would not only have to compete in more extensive fields with larger and more heavy balls. It would also have a lot more run. How much? According to the study, the most players would go through about 10 kilometers per game to cover between 12 and 13. In practice, Authors abound of the report, that equals much more play time and “enormous physical effort, both for resistance and physical condition” of athletes. The same barriers? Another aspect that would vary if we redesigned the fields for men and women to face the same level of demand is that of barriers in cases of faults. Due to the size differences, the female are narrower and more low, so they cover a vertical angle of 10.4 degrees. In the case of men, 11.25 are reached. That affects the possibilities of a successful stop. “The chances of a successful free kick increase.” The debate, served. Although SRF data is interesting, it is not the first time that the debate about whether women and men should compete with goals, fields and balls equal. In 2021 the University Campus of Football Business (UCFB) published An article in which he stressed that issue and recalled that different balls, networks or fences are already used in other sports depending on whether male or women compete. “Why don’t you do in football?” I left driving UCFB, a question that has arisen On more occasions In recent years. “Any opinion that defends the change in the size of the goals is received with accusations of sexism, but there is an argument against: passively accepting the measures originally designed for the male game is a form of sexism in itself,” Reflect. “If the emotion is neglected and pure logic is pursued, the change in the size of the goals can improve the game.” Would you favor or harm women? That is the key question. Despite the calculations disseminated by SRF, there are those who warn that applying ‘corrections’ for men and women to face the same degree of demand on the grass would harm the latter. The reason? Beyond the accusations of “sexism”, some voices warn that they would complicate the expansion of women’s football. “It is already quite difficult to find a field to play! There are not enough teams with a budget to have its own field, so now they share it with the masculine. Are you going to measure the land on Saturday for the male match and change all the measures then for Sunday’s female meeting?” warns The player Rachael Yankey In an interview with UCFB.

The almost instantaneous load batteries and a shelf life close to eternity are taking shape. Thanks to quantum physics

by

Integrated circuits containing all our electronic devices, Solar panelsmagnetic resonance machines, The lasers or the atomic watches that allow the human being to measure time with an unprecedented precision would not be possible without the knowledge he has given us Modern Quantum Theory. And, of course, without this model we would not have Quantum computers. Objectively, and it is not at all an exaggeration, quantum physics is present in much of modern technology. During the last five years several research groups, such as the PSL Research University (University of Recherche Paris Sciences et Lettres), which resides in Paris (France), or that of the University of Pisa, in Italy, have tried to use the basic principles of quantum mechanics to point A new generation of batteries. And the results are getting little by little. This is its starting point: they pursue to use overlap, entanglement and superabsorption to tear down the limitations that electrochemical batteries currently impose. The quantum storage of energy is an ideal that is increasingly closer The main difference between quantum batteries and conventional electrochemicals is that the latter depend on chemical reactions, while quantum devices seek to store energy in the quantum states of some particles, such as, for example, photons. It seems complicated, and it is, but the really important thing for users is that quantum batteries on paper can be loaded almost instantaneously, they will have a much higher energy density, and, in addition, their degradation will be minimal as the load cycles pass. Quantum batteries can store energy in a superposition of multiple energy states simultaneously It sounds wonderful. So much, in fact, that seems science fiction. However, it is very important that, as we have just seen, let’s not overlook that their principle of operation will be, if they finally come to fruition, very different from that of conventional electrochemical batteries. Existing theoretical proposals argue that quantum batteries They can store energy in an overlap of multiple energy states simultaneously, which should allow them to deliver a much greater energy density. In addition, your theory load will be much faster, even almost instantaneous, due to the collective quantum effects of the quantum units that make them up. The most amazing thing in this field is that the higher the capacity of the quantum battery, the faster it will load. It is an intuitive characteristic, it is true, but it is possible precisely thanks to the collective quantum effects I just talked about. However, this is not all. And it is that on paper the degradation that these batteries will experience during energy transfer will be minimal, so your useful life will be much greater than that of conventional batteries. Perhaps, even, almost eternal if we compare it with the longevity of the human being. So far all the work that researchers had carried out in this area had condensed in purely theoretical models, but this panorama has just changed. And it is that several scientists from the universities that I have mentioned in the second paragraph of this text have published an article very interesting in which they propose How to make a quantum battery. Your idea is to use superconductor circuits produced with materials that exhibit essentially zero resistance at low temperatures. They have not yet manufactured anything, so it is evident that the hardest work, the experimental, is still pending. But there is no doubt that this proposal invites us to tie the future of quantum batteries with reasonable optimism.

What should you do if you find one in your mailbox

Phishing has been a problem for many years. Every time we find more sophisticated techniques To try to pique and do with our data or violate the privacy and safety of our devices. In this case, it seems that tactics have evolved, taking advantage of the postal mail of our house and thus skipping all the filters of the usual e-mail customers. The play that we are going to talk about next has been meeting a few years and more and more users who have informed of it are. It is a tactic that seeks to imitate Amazon through a promotional card in which they promise free products and commissions of up to 40 euros in exchange for scanning a QR code. It is a trap Internationally located of which we have seen examples in the United States, the United Kingdom, Germany, France and even in Spain. A new modus operandi. Criminals send physical letters with the Amazon logo in which the recipient is invited to join an alleged “test club” of new products. The letter promises free items and a commission that can reach 40 euros, as seen in several of the examples that circulate through Redditand in this Another user. The letter maintains that, to participate, we must scan a QR code that supposedly allows “registering the name and contact information.” The final hook is a suspicious contact email. Click the image to go to the publication Why this scam works. That postal mail is used instead of using e-mail in this practice is an intelligent decision by scammers. Physical letters generate more confidence than electronic messages, especially in older people less familiar with digital scams. In addition, they avoid all Antispam filters and security systems that block fraudulent emails. The QR code adds an additional layer of difficulty detecting the scam, since it is not possible to see with where to redirect the link. An international problem. This fraudulent campaign has been detected in numerous countries. According to experiences that other users have shared, identical letters They have appeared in the mailboxes of the United Kingdom, Germany, France, and even Spain, always with the same format and similar promises. Knowbe4 cybersecurity company has identified This technique through one of its employees, who also received this letter. The company contacted the scammers to learn more information, revealing that the plot could only mean a new method to transfer funds illegally, a fake review campaign, and other similar scams. If you receive it, ignore it. Amazon never contacts potential customers via postal mail not requested to offer test products. The company has specific official channels for its testing programs, which require prior registration and never promise cash commissions. In fact, as we can see, the contact email does not correspond to any official Domain of Amazon. The company has a website where they report what to do if we have been victims of ‘Brushing‘, the scam in which we receive an unplayed package or letteran increasingly common tactic. Throwing the letter directly to the trash without scanning the QR code or responding to the email is, surely, the best you can do. Older people and those less familiar with the Internet and technology are the objective of greatest risk in this type of scams, so It is convenient to run the voice to make sure they are also aware and thus avoid falling into the trap.

I’ve been sleeping badly for years, so I’ve tried “sleep headphones.” They haven’t been what I expected

by

I’ve been sleeping for years regulate. The classic culprits are discarded: I don’t take late or copiously, I don’t drink alcohol, I don’t take caffeine, I do sports, No mobile abuse just before going to bed… Simply I find it hard to fall asleep and sometimes wake up at several times during the night. So I wanted to whose car more and more manufacturers are climbed. In my case I have tried the Anker Soundcore Sleep A20. Let’s see how. What they are and what they promise Sleep A20 are wireless headphones designed exclusively for sleep. The first thing for what they attract attention: they are dwarves. The second: They are very light. The third: its profile is very low, they do not stand out from the ear. The closed box. Image: Xataka. Image: Xataka. Image: Xataka. They also come with several silicone and “wings” tips to adjust it, something especially important in some vermin that we are going to take sleeping for hours. The important thing is that they are not just headphones: Its application includes several environmental sounds, sleep monitoring and specific functions for the night. They can work in two modes: Bluetooth mode to reproduce any sound from our mobile. Sleep mode with soured sounds in the headphones. The experiment The first night was adaptation. I had never slept with a headset in my life. In addition, I usually sleep sideways. It seemed unlikely that a headset did not bother me. Minipunto for these, because I immediately forgot that I was wearing them. The flat design and the soft, gummy, flexible material, made it barely noticed additional pressure. Zero problem. They stand out practically anything. Image: Xataka. Image: Xataka. Then there was the issue of listening. Put to try, I let the application surprise me with its own proposals, which they call “brain waves with the” created specifically to help us fall asleep. We can choose whether listening to them only for a while, only until we stay asleep or all night. I tried the three: Only for a while: It gives what it promises. If we mark 45 minutes, at 45 minutes it will stop ringing. Only until we stay asleep: The same, detecting the moment we fall. All night: What a bad time. The sound made me wake up a couple of times, something disoriented by him. Perhaps it is a personal issue and there are people who have a reparative dream with the headphones sounding throughout the night. It is not my case and I advise to set the timer in a generous way to ensure that the shutdown will occur. The Yay and the Nay There are four elements that work really well here: Exceptional comfort. They have never been a nuisance. They are soft and with the low profile they are not noticed or sleeping sideways, as a soil alternate. Spectacular battery. 14 hours in sleep mode is something that I can never check for myself. After seven hours of night use, when they woke up they still had about the remaining 50%. Passive noise block. Without active cancellation, but with the right tips they isolate surprisingly well. Reasonable, at least. Useful sleep monitoring. The application records sleep phases, number of turns in bed and preferred position. There is enough correlation with what it says My garmin on duration and phases. And then there are four other elements where they fail. Mediocre audio. That nobody expects audiophile quality. Nor is it the vocation of these headphones. The sound is functional, music lacks depth and warmth. Very limited pre -recorded sounds. There is some variety, but many sound compressed and artificial. The most effective are the noise of color (white, brown, pink). Application Faluta. He tells me that I slept 16 hours when the reality is that at seven hours I took them off and left them on the bedside table. I should understand that absolute immobility for nine hours cannot be equivalent to very deep sleep. In addition, it is not very intuitive when applying one way or another. Problematic tactile controls. In the dark it is easy to activate some function. About the application Falutathere is an example. I have not sleeping 11 hours possibly from the day before my birth. That lack of logic in detection is a negative point. Yes, you can see how much I move during the night: my wife says that 16 turns seems like a fairly reasonable figure. The data collected by the application. Image: Mockuuups Studio, Xataka. Also Atina that I am only able to sleep aside, and I have quantified what I already imagined: I usually sleep more towards the side of the edge. The final verdict The big question with these headphones is whether they really help sleep better. The answer, in my experience, is not. I did not notice differences between the nights with them sounding before sleeping and the nights without them. I thought That the scientific approach of pre -registered sounds would better induce sleep, but it has not been so. My Garmin data, with me every night, indicate very similar patterns with them and without them. And something worse when I tried to wear them playing all night, as I said before. At 150 euros are not cheap, but Yes I see them a clear target audience: the people who need to fall asleep listening to something. For that, I don’t think there are much better options for the low profile and night comfort. And without disturbing the bed couple, if there is. There I see an obvious sense. But for those who do not sleep wonderfully and look for allies of any kind to fall asleep, and not to simply hurry a podcast of True Crime Until we fall round, at least in my experience, these headphones do not miracles.
