This camera as small as ambitious is not perfect, but almost

by

There are cameras that arrive with so much noise that it is impossible to ignore them. The DJI OSMO POCKET 3 It has been one of the most commented in recent months by its size, its versatility and its surprising performance for video. But … is it as good as they say? In this New 24/7 episode published in the YouTube channel Se xatakaour partner intends to find out: record with her for a whole month as the only main camera, getting to record resources for videos such as the Versus of the Samsung Galaxy A56 against the iPhone 16E. “I have asked to use it only as my main video camera,” he says at the beginning. Neither loose tests nor support clips: a real and continuous use. What comes from there? The first thing that attracts attention is how much such a small format can give. “The first time I saw the Osmo Pocket I judged her quite bad Because I thought something so small could not record anything well. ” And yet, the thing changes after several days recording real plans for other Xataka videos. There are strengths that do not take long to appear. The stabilization of three axes, the automatic approach, the Face Track mode. “It works quite well, it is fast and does not have many failures.” And the design with folding OLED screen 90 degrees makes you record yourself as simple than it seems. But there are also decisions that surprise. And not for good. What about the digital zoom? And why can’t you record vertically without trimming resolution? The camera allows you to record vertically, but it does so digitally the image. And although that can be enough for social networks, It is not ideal To get the most out of the sensor. How is it possible that you have to install an APK today if you use Android? Throughout the video, advanced functions such as recording in logarithmic, settings in 10 bits and wireless microphone performance are tested. There is also talk of autonomy, fast charging and accessory pack. At this point, it should be specified: autonomy is approximately an hour and 50 minutes recording at 4k at 60fps, which can be extended up to about 3 hours and 20 minutes with the battery grip. Now, not everything is as round as it seems. And some things could directly improve. As for the zoom, during the first tests it offered quite poor results, but after a Firmware updateDJI has managed to improve. It is not perfect, but at least now it is usable in specific situations. “It is one of the most useful and comfortable cameras that I have ever tried to create content,” concludes our partner. But that means that it deserves what it costs? And that has no rival in its format? Give it to the play. Because this time, the 24/7 is for this interesting camera. And if you want to know more about other outstanding devices in the world of photography, we invite you to read our articles about the Canon Eos R1 and OM System OM-3.

In the same way that you would not be able to play a game of Soccer with moccasinspersonnel recruitment experts recommend Adapt the curriculum to the job offer to give Priority to skills that the company claims. This Curriculum adaptation It is a basic strategy when applying to any job offer today. In the early 70s, Bill Gates used that same strategy to Adapt your academic skills In registration applications for Yale, Princeton and Harvard universities: three universities, three different Bill Gates. An actor: three characters In his autobiography ‘Code Source: My beginnings’Bill Gates tells how he faced his admission application in some of the best US universities. Although in the case of the young Gates it was almost a joke with himself, his strategy, reminds to which any candidate who runs to a job offer should do. In autumn of 1973, Bill Gates participated in a play during his last year of high school. It was there when he discovered in the theater a new way of relating With other young people and show aspects of your personality that were in the background in other activities that were usually carried out, such as programming or making long excursions through the mountains. Just then, Gates had to send income requests for universities. That raised some doubts about what his Labor future. The options that were raised were to go to Harvard and follow in the footsteps of his father as a lawyer; orient towards a more political profile studying public administration at Yale; or go to Princeton to train as an engineer and develop software, something he had already done His first steps. Bill Gates tells in his book that “while filling the requests, I experienced with my personality. As I had learned in the theater class, each was a performance: An actor, three characters“The millionaire said. “For Princeton I said that I wanted to be an engineer who knew how to develop software. I boasted with examples of my programs and emphasized my mathematics notes. To Yale I said that I wanted to study public administration and, perhaps right, highlighting my experience (like Ujier during a couple of summers in Washington DC), my fondness for the boy scouts and my interest in dramatic art.” However, the request that had more weight for Gates was the one he presented to Harvard, “as I wrote in my essay, I expressed my inclination for business and law,” following his father’s professional steps. All gates, all certain Sincerity It is something that recruiters They value very positivelyso adapt the curriculum for a certain position It does not imply lying in skills, but to give priority to those who have A positive impact In the position to which it is postulated. “We expect sincerity. If a person comments that he is good to work as a team, but in the day to day he avoids participating in meetings, that is where we see that there is an incoherence with what he explained in the interview,” he explained Lidia Sanz CostaTechnique of Selection, Development and Training in companies IMAN. The “Three Bill Gates” presented by the millionaire in their respective income requests They were realbut little was going to serve a software engineer to have learned the values ​​of the scouts, or have knowledge of dramatic art. For that reason, the young Gates arranged to play a paper highlighting only the skills that They contributed value to their candidacy. In this sense, it is increasingly common to use the help ofChatgpt to adapt the curriculum to a specific job offer. This automation applied to curricular adaptation will also take into account other factors such as including Keywords and skills what would priority to office, preventing them from candidate monitoring algorithms (ATS) Believe your curriculum In the first rounds of the process.

Wild urbanization, heat and cockroaches have turned Brazil into the perfect destination of a creature: scorpion

by

In Brazil they have realized a serious problem derived from a common evil in a large number of countries. It was intuited that Wild urbanizationadded to the climatic changes And the extreme heat of the planet were an equation that did not predict anything good. The nation has discovered, very much, something else. The atmosphere of many of its cities has led to authentic cockroaches colonies and, after them, those that devour them: scorpions. Silent invasion. Yes, Brazil is currently facing an alarming Scorpion proliferation In many of its cities, a direct consequence of uncontrolled urban growth and climate change, which has transformed urban environments into ideal habitats for these arachnids. How much? According to the study Posted in Frontiersbetween 2014 and 2023, more than 1.1 million bitesa 155 % increase In just a decade, and the projections estimate up to two million new cases between 2025 and 2033. The situation is especially critical in densely populated areas and with precarious services, Like favelaswhere the combination of crowded housing, accumulation of waste and sewerage systems without control has created the perfect scenario for the expansion of scorpions. These creatures find shelter in cracks, debris and pipes, have abundant food (The cockroaches), and enjoy constant temperatures and high humidity. Plus: Some species are capable of reproducing without mate and can survive more than a year Without feeding, which makes them a resistant threat and difficult to eradicate. A public health crisis. The Guardian told that the increase in temperatures, intense rains and prolonged droughts (increasingly frequent patterns in the context of climate change) have favored the expansion of scorpions, whose natural habitat is now complemented by those Modified urban environments For the human being. Previous investigations had already warned of these animals for adapt to citiesbut current data has confirmed that the phenomenon has climbed to become a health crisis. Only in 2024, it is estimated that almost 200,000 people were chopped And at least 133 died, although experts warn that real figures could be much greater, since many affected do not seek medical attention and are treated at home. Although only 0.1% From the bites it is lethal, the most vulnerable victims are children and the elderly, who run a greater risk of dying even with a single sting. For the rest of the population, the symptoms include intense pain, burning, swelling, redness, tingling and nausea, with a recovery that lasts several days. Misinformation and prevention. And here comes one of the legs to deal with the problem. The British media counted That one of the most complex challenges is the erroneous perception of scorpions. According to researcher Manuela Berto Pucca, they are not natural aggressors of the human being, but They act in self -defense. In fact, they perform key ecological functions when regulating populations of urban insects, yes, such as cockroaches. However, its presence in inhabited spaces has generated an understandable and growing fear, especially among the poorest populations, where the fear of a bite is part of everyday life. The key, According to expertsis in prevention: keep the spaces clean and without moisture, seal cracks, place grilles in drains and carefully check footwear, clothing and towels before wearing them. In addition, the Brazilian health system offers Free treatment and antidotes in certain emergency centers, but researchers insist on the need to act quickly at any sting, without waiting for symptoms to get worse. A call to action. Finally, it should be clarified that the phenomenon It is not exclusive from Brazil. Countries like Paraguay, Bolivia, Mexico, Guyana or Venezuela too They have experienced a worrying growth of “Scorpionism”, The medical term that defines the reactions to these bites, making it a health crisis of regional scale. And in Europe? There are more than 35 native species of scorpion, but there are no comprehensive studies on their populations or comparable expansion has been observed. However, what is happening in South America serves as a global warning on the combined effects of that uncontrolled urbanization and climate change. The international scientific community has stressed that this is an avoidable emergency if more sustainable urban policies are applied, effective sanitation systems and public education and prevention campaigns. For Pucca and his colleagues, the current situation should serve as a catalyst for urgent actionsnot only to protect public health, but also to recover the balance between humans and the rest of the urban ecosystem to which these creatures also belong.

In the exciting world of the supernovas this newly discovered has something unique: its form is perfect

by

Identifying a Supernova is an event that astronomers usually celebrate with enthusiasm. And it is not for less if we consider that it is One of the most violent events with which we can run into the cosmos. Knowing them better is very important because it can help us understand more precisely what the latest stages of The life of mass starsand also the mechanisms that explain how the material caused by stellar synthesis can lead to new star systems. The mathematical tools handled by astrophysics current nuclear fusion that take place in the nucleus of mass stars. During the stage known as the main sequence, stars obtain their energy from the fusion of hydrogen nuclei. As this chemical element is consumed, the star begins to produce helium nuclei, and, of course, its composition begins to evolve. During this process a huge amount of energy is released and the star is forced to continuously readjust to maintain hydrostatic balance, a phenomenon that is the result of the coexistence of two opposite forces capable of compensating. One of them is the gravitational contraction, which compresses the subject of the star, pressing it without rest. And the other is the radiation and gase pressure, which is the fruit of the ignition of the nuclear oven and tries to expand the star. ‘Teleios’ is the perfect supernova If the star is massive enough will begin to consume its helium reserves and produce new carbon nuclei, while maintaining the hydrostatic balance we have talked about. And if the star has enough mass will not stop in carbon production. When this element is exhausted in the nucleus, it will be readjusted, compressing and increasing once again its temperature to stop the gravitational collapse. From this moment the carbon nuclei will enter into ignition through nuclear fusion processes and the production of even heavier chemical elements will begin. While in the star’s core is being carried out Carbon fusionin the immediately superior layer the ignition of the helium is maintained. And above this, of hydrogen. The iron core suddenly contracts under the enormous pressure that all layers of material that it has above the material exerted on it During star nucleosynthesis, stars acquire a layer -shaped structure similar to that of an onion. In the nucleus lies the heaviest element, and from there we are ascending by layers finding more and lighter elements. If the star has accumulated sufficient mass there will come a time when the nucleus will be essentially constituted by iron, and from this chemical element it is not possible to obtain more energy through nuclear fusion processes. At that time the radiation and gase pressure is not enough to counteract gravitational contraction, so Iron core suddenly contracts under the enormous pressure that all layers of material that it has above. The star has lost the hydrostatic balance. At this moment all this matter loses the support that the nucleus exercised, which is now much more compact, and falls on it with enormous speed. When all that star material touches the surface of the nucleus there is a rebound effect that causes it to be fired with a huge energy towards the stellar medium, being disseminated. A supernova has just been produced. Some of them are so energetic that for a few seconds they emit more light than the entire galaxy that contains them. This was probably what happened to ‘Teleios’, the remnant of a supernova recently discovered by an astronomer team from the University of Sidney (Australia). The remnant is nothing more than the material that is spread in a region of space after the production of a supernova In the field of Supernovas, the remainder is nothing more than the material that is scattered in a region of space after the production of a supernova. It usually acquires the shape of an expanding bubble in which it is possible to identify an external and brilliant region in which the shock wave and a diffuse interior section occurs constituted by dense and cold dust and dust. The image we publish on the cover of this article recreates a supernova in the most reliable way possible, and in it we can clearly observe the two regions in which we have just inquired. Astronomers from the University of Sidney have identified the remnant ‘Teleios’ using the Australian Askap telescope (Australian Square Kilometre Array Pathfinder), and have realized something very interesting: its geometry is almost perfectly circular. It is very unusual that the material left after the production of a supernova acquires such a perfect geometry. Although these astrophysics shuffle several scenarios that could explain this morphology, in Your scientific article They propose to carry out more observations to determine why ‘Teleios’ is so different from other remnants. The identification of the conditions that have given rise to this cosmic object can help cosmologists to understand better What happens during the production of a Supernova and what parameters delimit the evolution of the remnant that will remain in space long after this great explosion occurs. In fact, these Australian astrophysicists have estimated that ‘Teleios’ is at a distance between 7,170 and 25,100 light years.

Reducing weight loss carbohydrates seemed a perfect plan. We have just discovered that it comes with unforeseen risks

by

Carbohydrates or carbohydrates are a fundamental macronutrient in our diet. They represent, together with the fats, the main energy contribution to our body. Carbohydrates are also protagonists in some diets destined for weight loss, diets based on the fact that, in the absence of these nutrients, our body will resort to the energy stored in their fatty tissue. A plan that is not infallible. DNA damage. A new study has found a mechanism that could link low carbohydrate diets with a Risk increase of suffering from colorectal cancer. The union link would be in the microorganisms that reside in our digestive system, our intestinal microbiome. In a study conducted with mice, the team responsible for the analysis observed that these types of diets could worsen the deterioration of DNA caused by some of the microbes that usually inhabit our digestive tract. This facilitates the appearance of polyps that in turn increase the risk of appearance of this type of tumors. “Colorectal cancer has always been seen as the consequence of a number of diverse factors, including diet, intestinal microbioma, environment and genetic,” explained in a press release Alberto Martin, co -author of the study. “Our question was, does the diet affect the ability of specific bacteria to cause cancer?” Three diets under study. In his study, the team tested three types of diet: a “normal”, a carbohydrates, and a “western” rich in fat and sugar. He did it by combining these diets with different types of usual bacteria between our intestinal microbiota and suspects of keeping some kind of relationship with the risk of colorectal cancer. They found a combination of diet and microorganism with potential to trigger adverse relationships, that of the low carbohydrate diet and a variety of bacteria of the species Escherichia coli (E. coli). They observed that this diet encouraged production by the bacterium of the colibactin, a compound with the ability to damage the DNA and with it of producing cancer. The key I could be in the fiberthe team points out. This type of diets facilitates inflammation, altering the microbial community of its interior, which in turn creates an ideal environment for the propagation of the E. coli. A fallen barrier. The team also observed that the mucous barrier that separates epithelia cells (the outermost cells of the intestine) of bacteria was reduced, which could also facilitate that colibactin reaches intestine cells. This would increase the harmful potential of the compound. The details of the study have been published In an article In the magazine Nature Microbiology. And what about humans? Studies with mice have an obvious limitation, and it is that extrapolating what is observed in these rodents to our own species is not always possible. The team He stood out for it The need to confirm their findings in people, although they were also optimistic about the possibility that their study could be applied in cancer prevention. The microbioma in the spotlight. This is not the only recent study that has put in the spotlight to the bacteria of the species E. coli already the colibactin in regards to colorectal cancer. A few days ago We had the news of A study Made with patients from 11 countries who found exposure tests at an early age to this toxin could be linked to an increased risk of these types of tumors.

Japan had in Mexico the perfect ally to fill the USA with hybrid cars. That is about to end

by

In his battle for torpedoing every car that comes from outside the United States, Donald Trump’s government has imposed a hard 25% tariff to every car that is manufactured outside its borders. And he has also raised an economic wall for cars manufactured there with pieces from abroad. That measure is especially shocking for Europe, which sold vehicles to the United States by value of 38.9 billion euros in 2024. But, above all, it is for Japan. The country had in United States a sales reef. A huge market that was willing to buy its cars, especially hybrids. It is now in a real problem. Everything that comes from Mexico will have to pay tariffs. Everything that comes from Japan will have to pay tariffs. And its presence on American soil is minimal. The Japanese Balancing Game Complex The automobile industry for Japan is especially important. To understand it, just look at the size of its exports. Until last year, Japan was the country that sold more vehicles outside its borders. His companies have a huge tradition, from giants such as Toyota and Honda to smaller companies such as Nissan or Mitsubishi and others with great recognition such as Mazda or Subaru For its growth, Japan installed new vehicle factories in the United States in the 80s. They produced there but The pieces arrived from Japan So the costs were minor and, in addition, generated wealth in their local market. Now, Donald Trump threatens to destroy that way of working. Before they had already achieved the favor of Americans with good cars in the 60s and, above all, a perfect opportunity with the oil crisis in the 70s. Now the car represents 3% of Japanese GDP but cars sold to the United States added 28.3% of all exports made to the North American country. The impact of maintaining a 25% tariff is such that Reuters He points out that he can impact a 0.2% drop in the country’s GDP. The United States is, for half a century, the main market of its exports in the car market. In 2015, for example, They sold 1.7 million cars In the North American country, for the more than 700,000 units that sold throughout Europe. Its weight is such that in 2023 they sold cars worth 41,070 million dollars to the United States. The figure almost reached that registered throughout the European Union in 2024, when it placed in the US market 38.9 billion euros (42,560 million dollars) in vehicles. They are figures that take into account the production of cars in Japan but, in addition, Japanese firms have found an ally in Mexico in recent years. His proximity to the United States has allowed him to get huge performance to his cars. They offer more affordable vehicles than those sold by local brands and, in addition, they are manufactured at a much lower price. The path taken by Donald Trump has made Jump alarms Within the Japanese government. In fact, the United States already confirmed yesterday (April 7, 2025) that Negotiations with a Japanese delegation opened high level that had been sent to negotiate the terms of the new tariffs. It must be remembered that, in addition to cars, the United States has imposed an added tariff of 24% to all Japanese imports, which is a commercial attack on the largest foreign investor in the country, in data collected by EFE. In Bloomberg They encrypt a 0.59% drop to growth forecasts due to these tariffs. According to calculations echoing ReutersJapan could lose 17,000 million dollars as a result of these tariffs. In Bloomberg They emphasize that American manufacturers do not pay tariffs in the United States for their car sales but claim that strict security measures, among other regulations, prevent them from acting there competitively. It is a case similar to the European where the United States has difficulty selling its cars. On the contrary, the Customer Caladero that Japanese companies have in the United States is huge. Bloomberg points out that 23% of Toyota’s sales worldwide went to the North American country. The figure grows to 28% in the case of Nissan and … at 83% if we talk about Subaru. The country’s weight has been growing thanks to the fact that they have been turning with the Hybrid car salesa Japanese specialty. They are very bad news for brands like Toyota. However, the sanitized accounts of the Japanese giant allows you Reuters. The fall would be 8% for Honda. But the provisioning that Japanese companies make of pieces produced in Mexico They are a real problem for smaller companies or with more gloomy economic perspectives. Mazda and Nissan would be the most affected, with a 59% benefit drop for Mazda and 56% for Nissan. Nissan is, without a doubt, the one who has a more complicated horizon. The company is looking for a buyer who holds him from a dramatic fall in his income that It has taken 9,000 layoffs. The Japanese government has pressed without success for Honda to buy To the company. And now It is Foxconn that positions itself as the alternative that sounds more strongly. Focused on the hybrid car and with an almost testimonial presence among the electric ones, the Japanese need to reach an agreement with the United States urgently. In Europe they need to sell more electric cars if they want to meet the European regulations in 2027 Or, as a minor evil, reach an agreement with other manufacturers. At the same time, In China they have it more and more complicatedsince the market has moved to the electric car. And Chinese competition is, more and harder.

Half of Catalonia has its contaminated aquifers. And the rains are the perfect excuse to do nothing

by

In January of this year, the Catalan Agència de l’Aigua He updated his data on areas vulnerable to excess nitrates of agroganadera origin. The figures are a jug of cold water (and very polluted): 49.2% of Catalan municipalities They have contamination levels by nitrogen compounds above the legal. That is, 39.9% of the surface of Catalonia. It is a huge problem that does not stop growing, but that the rains of these weeks can end up making invisible. And, at a time when the Government began to be forced to take action, postponing them would be a difficult mistake. Doesn’t it stop growing? As Antonio Cerrillo explainedin 1998 “the percentage of municipalities cataloged with vulnerable area was 21.5%of the total; in 2004, the figure rose to 33.7%; in 2009 it reached 44.2%; in 2015 it was 44.5%.” It is true that some municipalities (three: Blanes, Cubells and Tavertet) have left the list because they have allowed the indicators; But, on the other hand, eight (Corbera d’Ebre, Gavet de la Conca, Jorba, Marçà, Pla de Santa Maria, Perelló, Ponts and Sant Sadurní d’Alcoia have entered). According to the Generalitat, the trend was stable, but “with a slight increase in nitrate pollution in certain areas.” Now the indicators will improve. There is no doubt about that. Above all, because a part of the problem was related to drought. The mechanism is simple: agribusiness contamination filters to the subsoil and there meets the huge aquifer system of the country. If there is a lot of water, those nitrates are diluted and the legal limits are not overcome. If there is not, the alarms jump. Right now, the Catalonia reserves They are at 76.46%, those in Barcelona are at 78.83%and those of Girona (the lowest) to 47.28%. Right now, while I write this, aquifers throughout the country are filling with water and, by pure logic, the situation will improve. However, the rest of the problems persist (or increase). Above all, because you have to keep in mind that those nitrates, Those purines They do not appear alone: ​​they are the result of hyperintensive models of agroganade exploitation. Models that base part of their profitability on Not having to put their negative externalities In the results account. And it is not a strictly Catalan problem (although it is true that it affects especially): according to the citizen network of nitrate measurement, almost 60% of Spanish underground waters is contaminated by nitrates and growing. The matter is such a caliber that also reaches reservoirs and evidences the country’s disastrous water management. In summer 2013, 161 municipalities in Castilla y León They discovered that had been drinking contaminated water for years without knowing it. It’s alone An example of the rosary of problems We have been seeing. All reflect and, above all, take action. Antonio Cerrillo saidthat the Generalitat “prepares an order to review the areas of the territory with groundwater contaminated by nitrates from livestock purines.” But the truth is that we always go with the foot changed. A good example was that of “Royal Decree that establishes rules for sustainable nutrition in agrarian soils“which was approved with more than three years of delay. The same three years that it took to transpose the”European Directive related to the quality of the waters for human consumption“It is our way of doing things. As we said days ago, March rains have given us a historical opportunity to save the country’s aquifers. But it will also give a victory (pyrrhic, but victory after all) to those who manage the problem they can use to leave us in worse situation we have. It’s not The first time what’s happening.

Coffee has no cholesterol but does raise its levels. And someone has discovered the perfect elaboration to limit it

by

We are increasingly clear that coffee is a food with Positive properties for our health. However, it has traditionally been surrounded by many myths. Many of them Caffeine relatedbut also some related to things as serious as supposed damage to the heart and its incidence in cholesterol levels. And the latter is half myth. Because coffee has no cholesterol, but compounds that, depending on how we prepare it, will influence more or less on LDL (“bad cholesterol”). Cafestol and Kahweol. Let’s see, if coffee has no cholesterol, how do some of its compounds do have an impact on cholesterol? The reason is that we do not drink coffee in grain, but we crush it to get a ‘dust’ from which to get an extraction and, therefore, the coffee cup. When we break down the coffee beans the oils of it are released, and in them we have fat -soluble diterpenes that are those that have an impact on blood cholesterol levels. Mixed effects. These compounds have some health benefits, since they have anti -inflammatory and anticancer properties. It has also been observed that it favors osteoblastic activity that helps bone health and can have antidiabetic effects. However, the contradictions are there. Although both have a similar effect, it is cafestol that acts as an enemy of FXR receptors, inhibiting the synthesis of bile acids in the liver and, therefore, reducing its effectiveness by eliminating the cholesterol from our body. When this occurs, cholesterol levels increase, with more notable increases in LDL cholesterol. The investigation. Does this mean that I must stop drinking coffee? Not much less, since although these diterpenes can influence cholesterol levels, lead It allows to maintain the cholesterol at bay. We are not talking about sugary drinks or alcohol, go. Now, in a investigation carried out by the University of Uppsala in collaboration with the Technological University of Chalmers have found the coffee preparation method that less Cafestol and Kahweol allows our body to reach. Processing. To do this, the team took two coffee samples from different offices resting machine machines every two or three weeks, with coffee varieties that included average and dark gall of five trademarks of ground coffee. Most machines use ground coffee, but a couple They grind before (the super -automatic). In total, eleven machines were analyzed, three that use coffee concentrate (mix with water). Compared the results with other preparation methods such as percolation, the French press, boiled coffee and samples of espresso. The goal is to see which one prepares coffee with the highest levels of both coffee and kahweol. And the result is overwhelming. Boiled coffee. In the upper graph we can see the concentration of coffee in the different elaborations and there is a clear winner, as well as an obvious “loser”. Previously, it had indicated that boiled coffee was the highest source of these diterpenes and was not as recommended on a regular basis. And it is logical because it does not filter coffee at all. On the contrary, the best elaboration to reduce coffee to the minimum possible is through filter coffee. Here there are variations depending on the filter material, but in the analyzes it is shown as the elaboration that, in a more consistent way, keeps the coffee levels in coffee. Interestingly, we can achieve the same effect by preparing boiled coffee if we like it more and then filtering it, which is the icon of the chart sock. Too many variables. A problem that researchers were found is that, although the concentrations of diterpenes in the machine of the machines was always inferior to the preparations of boiled coffee and other elaborations such as French pressthe concentrations vary significantly between machines and between the sampling intervals. Of the machines, those that use liquid concentrated coffee have lower levels of diterpenes, similar to those of the filtered coffee. Typologies. This may be due to the type of coffee that is placed in the machine or the temperature at which they heat the water, but there is a more disconcerting case: that of the espresso. The researchers comment that a “considerable and clear explanation variation is observed in the concentration of diterpenes among the four samples analyzed”, recognizing that it is something that requires an additional study because it could be relevant to the usual consumers of this preparation. “It can contain high levels of substances that raise cholesterol.” It is the warning of this machine in a Swedish office photographed by Uppsala University And limitations. The team has focused on measuring the concentration of diterpenes, ensuring that it is known that they negatively affect other lipoproteins such as triglycerides, but that it is an aspect that they have not taken into account for their research. In addition, they also recognize that, although the results are solid and there is a “better way to prepare coffee” to maximize coffee, the study has important limitations. On the one hand, the size of the sample, since these are several collection maintained over time, yes, but of eleven concrete machines when there are many, many more in the market. On the other hand, there are variables such as water pressure and temperature, contact time between ground coffee and hot water, grinding or grain gall. Next steps. Come on, too many things, something logical taking into account that there are not only many different coffee machines, but a huge fan in terms of water and coffee gut. It is something that, they point out, it would be interesting to analyze in the future, as well as studies that compare coffee consumers of companies with coffee machines in front of others in which they use paper filtered with paper. In whatever, there are many studies and they themselves comment that “long -term prospective studies on cardiovascular results that could help confirm the causality of the associations” must be carried out between the diterpenes and the increase in LDL cholesterol. At the moment, I will continue to have coffee regularly, but … Read more

The perfect sample of “Manchego Bronze”

The stain is Wine landof cheese and of Better olive oil in the world. However, to the east of Ciudad Real There are not only rare earthsbut an endless plain that is occasionally dotted with the so -called “rings”. They seem mounds of land that rise on the esplanade, but they are really fortifications strategically built during the Bronze age. The peculiarity is that they are castles raised up, but also down, with some entering more than 20 meters on Earth to protect the most valuable resource in the region: water. And in a town in Daimiel is the largest well of the antiquity of the Iberian Peninsula. The rings. Between 2,200 and 1,500 BC on the Peninsula several cultures lived. In part of Castilla-La Mancha, the Manchego bronzeknown as the ‘MOTALLY CULTURE‘. In their day, these riot were fortified settlements with a circular shape that served both to house the sedentary population and to protect themselves to invasions and, above all, to control a resource as valuable as the water of the underground wells After their abandonment, these fortifications were dispersed by the Manchega geography and, over the centuries, they were covered by land and vegetation, forming those ‘motorcycles’ on the ground. Organization. There were rigs of various sizes, but generally These strengths had a diameter of between 30 and 50 meters. They were like a medieval protocastillo, with a series of concentric rings that acted as a wall and were available around a central tower. Like the strengths that were built in high areas to have a better strategic vision, the rigs were built around deep wells. The water, next to the grain, was the resource that was kept and protected in these ribs, and something curious is that there was a distance of a few kilometers between one and the other, so the groups could maintain visual contact between them. The population lived both within the fortress and its surroundings and it is estimated that the more cultivation controlled and more permanent was the presence of water, the more power the leaders had and the more influence the motilla in question. Speculating. There is a lot of space for the speculationsince the largest rigs would be those that were nerve centers for trade, while the smallest around them could be the home of one or more families that served as advanced points for the control of the territory, grass, crops and combat against who would like to take that great nerve center. Numerous weapons have been found in the tombs, so it is assumed that they were communities in permanent conflict. Azuer Motilla. And, among all the ribs, the crown jewel is that of Azuer. It was declared a cultural interest in 2013 and is unique due to its dimensions. It fulfilled the same defensive and commercial functions as the rest of the settlements of this type, but if for something it caught the attention – and it continues to do it – it is because of its dimensions. The central tower reached 10 meters high, so it was very visible in an exceptionally flat landscape. On the other hand, the well excavated to reach the water table at a depth of between 15 and 20 meters. In times of prolonged drought, this well could supply water to the inhabitants and, when it rained, the reserves reloaded again. It is estimated that this fortification is that allowed an enormous agricultural development in the region and the reason for its cultural interest is that it is considered the oldest well in the Peninsula. Difference between the height of the Motilla and what sinks on the ground to the water table Late discovery. The nineteenth and twentieth centuries were years when we worried about digging up the past. We made numerous and important discoveries that reflected the passage of the civilizations that preceded us and, being the rigs of some of them. It occurred at a late point, since it was during the last quarter of the last century when archaeologists began to dig up and study these constructions. Due to its dimensions, that of Azuer Motilla He was the most investigated in the entire age of the Bronze de la Mancha, developing Since 1974 more than one fortnight of excavation campaigns. And it is curious that, at the beginning of the excavations, the researchers thought it was funeral mounds. Manchegas fortifications. The Azuer is the deepest, but in the region there are numerous fortifications of this type. Currently, there are 29 in the province of Ciudad Real, as well as one in Toledo, another in Cuenca and one more in Albacete. The problem is that, although possible rigs to be investigated, it is complicated Incorporate new structures into the list. The reason is that they are difficult to locate. We talk about constructions with between 3,000 and 4,000 years, so human action and erosion have been able to end the characteristic form of mound and it is easy for us to overlook those that remain buried. The efforts have also concentrated to the Azuer Motilla. Its conservation is made, in part, thanks the price of tickets -10 euros per person- visit it. You can also do a Virtual route. Earrings. Therefore, it is very likely that little by little more riots are added to the list, but these peculiar strengths are not the only structures of the Bronze Age in La Mancha. It is known that they coexisted alongside height settlements called ‘Morras’, stationary cabins called ‘Fields of Hoyos’ and some sacred places with stars -oriented constructions, such as Bocapucheros In Almagro. Therefore, if you catch you close, it is a different activity and we can rarely visit something with 4,000 years behind you.

Google’s strategy to be the perfect partner of writers and programmers

by

Artificial intelligence chatbots (AI) have come to lend us a hand when words do not come out or the code stuck. They can help write that speech that does not finish flowing or solving doubts in the middle of a programming line. But there is a problem: to move forward with Prompts, one after another, it can end up being an obstacle, especially when we want to focus on a concrete part of the project. So much Chatgpt as Claude They have faced this challenge With a function that acts like a canvas, allowing to work directly on specific parts of the content. Now is Google’s turn, which has just presented the canvas of Gemini. As in the other proposals, we find an interactive window aimed at helping us to improve our work in real time thanks to several commands and format tools. It all starts with a draft. Returning to the example we mentioned at the beginning, if you are thinking of writing a speech to honor someone special, you can start creating a rather basic draft and gradually work the text. We will not have to elaborate a very precise prompt to indicate to Gemini to modify this or that part. It will be enough to mark a paragraph and ask him to rewrite him with a new style. And in programming? If we are working in software development, Gemini Canvas also promise to be very useful. In addition to receiving the classic, it helps to chop code that the wizard can offer us, the “canvas” will allow us to generate and prevail HTML/React code. This will result in that we can have a visual prototype of our web applications, which should help us in programming tasks. But this does not end in the preview. Once we have the preview of our project we can ask Gemini to modify input fields or add action buttons more easily. The combination of Gemini + Canvas should allow us, according to Google, work with Python scripts, as well as creating games that we can try directly in the browser window and run simulations. When will Canvas available in Gemini? Google has just announced the function and is now available worldwide, including the European Union. Acting it is as simple as having a Gemini or Gemini Advanced account. Once inside, you just have to look at the bottom of the chatbot text box, where a new button next to Deep Research now appears. From there, you can directly access this tool. Images | Google In Xataka | The videos of AI have broken the Instagram and Tiktok algorithms. Welcome to the new “AI landscape”
