The importance of maturation point at nutritional level

by

Banana is a one of the favorites of consumers and in this factors such as taste and nutritional contribution have some weight. It is evident for consumers that the taste of bananas, such as their texture, changes as fruit is maturing. It may not be so obvious, but the Nutritional characteristics From this fruit they also change in a similar measure with the maturation of the fruit. What exactly is what is happening? The banana is usually recognized as a great source of potassium (a banana can contribute about 10% of the potassium that we require throughout the day), but of course it is much more than that. This fruit It gives us diverse nutrients as magnesium or phosphorus, as well as vitamin B6. It also gives us macronutrients such as proteins, fats and hydrates. And of course, banana is a great fiber source. However, the proportion of nutrients that one of these fruits can give us depends on a factor that sometimes we do not take into account, its maturation. All fruit, when maturing, changes its chemical composition. This is what makes properties change such as texture and flavor. But this chemical change also implies something that we do not obviously perceive, a change in your nutritional contribution. The banana It is one Of the best examples of this. The key to change is in carbohydrates of this fruit. In immature bananas, green, starches predominate. With the passage of time and maturation, banana starch is transformed, through chemical changes that They give rise to transformation Of these starches in simple sugars such as fructose and glucose, as well as the disaccharide resulting from the union of both, sucrose. This change has as a consequence that ripe bananas have a softer texture and a Sweetest tastewhich makes them a sweetener for desserts and other recipes in which their sweetness is required. On the other hand, if what interests us is its fiber contribution, a greener banana will be our best option. In bananas predominates The call “Resistant starch”, Which we can consider a type of food fiber. Our small intestine does not break these compounds, but can be collected and consumed by the bacteria that reside in our digestive tract. That is why green bananas can be seen as a better fiber and fiber source Prebiotics. These “ferment” this starch, releasing fatty acid acids as the butyrate, which could have a positive impact on our health. Bananas are also a pectin sourcea soluble fiber in water. The glycemic index The changes given during the banana maturation process have another consequence, and it is that The glycemic index (IG) of this fruit It also changes. Thus, the IG of a more mature banana can be around the value of 51, while one without maturing could be around 24. A value above 55 is usually considered low, which implies that this fruit does not generate a considerable glucose peak. Of course, the glycemic load (CG) of this fruit can be considered moderate, with indices above 10 for both green and ripe fruit. The CG of this fruit would be around 13 in the case of the most mature specimens, being 11 in the case of the least mature. Our preference for more or less mature bananas surely focuses on its flavor and texture, but taking into account the specific properties of each degree of maturation can help us choose bananas depending on what we want to achieve. Green bananas: Fiber and prebiotic source Lower glycemic index Less sweet taste and firmer texture Mature bananas: Sugars replace fiber Greater glycemic index, but still low Sweet taste and soft texture (convenient for some recipes) All measures that tell us about the proportion of nutrients in fruits are estimates or averages. It is not possible to give a generic and universal value to the presence of a nutrient in a fruit since there are very different factors that affect its chemical composition. The degree of maturation is one of the most important. It is also one that can change even while the fruit rests in our pantries. But it is not the only one. The variety of the plant that has given the fruit, the climate of the place where it has been cultivated and the meteorology of the year in which the fruit has grown are factors that affect the taste and the nutritional characteristics of a fruit. What makes it special to degree of maturation It allows us to have some control over the nutrients that the fruit unit gives us to be able to adjust them to what our body or our palate requires on each occasion.

We have discovered a relationship between olive oil and risk of death by dementia, a point in favor of the Mediterranean diet

by

Someone could think that everything is already said, all investigated, on one of the fundamental axes of the Mediterranean diet, olive oil. Nothing is further from reality: research on this food continues and continues to reveal striking aspects of the liquid. And as regards striking relationships, perhaps the palm is taken by the fact that they keep the consumption of this derivative of the olive and dementia. 28%. A study published a few months ago established existence of this relationship. Specifically, the analysis responsible for the analysis observed a 28% reduction in the risk of death associated with dementia between people who consumed at least Seven grams of olive oil per day, compared to those who did not consume this liquid or did it rarely. Until now, some studies They had indicated us an inverse relationship between the Mediterranean diet and the cognitive deterioration associated with age. From there, establishing relationships between different aspects of these variables can help us better understand the link between Mediterranean diet and healthier aging. Changing ingredients. In its analysis, the team also studied the effects of replacing different sources of fat. Through a substitution modeling, they estimated that replacing five grams of margarine or mayonnaise daily with an equivalent amount of olive oil could be related to a decrease in the risk of mortality associated with the dementia of between 8% and 14%. A similar analysis did not detect similar effects when these fats were replaced by other vegetable oils or butter. 92,383 participants. The study was conducted from the macro -conformation Nurses’ Health Study II and Health Professionals Follow-Upwhich allowed to obtain Information about 92,383 participants. These filled surveys on eating habits every four years over a 28 -year period. The team divided these participants depending on their olive oil consumption: those who never consumed olive oil or did it less than once a month; who consumed up to 1.5 grams per day, who consumed between 4.6 and 7 grams per day; and a group for those who consumed more. The team extended its analysis over 18 years of the study and controlled aspects such as the general quality of the diet or the genetic predisposition to suffer from the disease. The details of the study were published In an article In the magazine Jama Network Open. What is happening? When establishing a causal relationship, it is always convenient to understand what mechanisms are operating behind this relationship between olive oil consumption and death risk associated with dementia. “Olive oil is rich in monounsaturated fats and contains components with antioxidant activity that can play a protective role for the brain,” He explained to the environment UPI Anne-Julie Tessier, co-author of the study.

Ozores was a day the most important person in Spain. To the point of delaying the premiere of ‘The Empire Contraataca’

by

He has died Mariano Ozoresone of the best known and box office directors in the history of Spanish cinema. Although his cinema has always been despised by critics, his films were infallible blockbusters that put on his competitors on his competitors. Including ‘Star Wars’, whose first sequel had to give in to the overwhelming power of Pajares and Esteso. Long live ozores. Mariano Ozores was one of the main exponents of the Spanish popular comedy since the sixties. His ability to connect with the public was notable thanks to a style that balanced the accessible and the irreverent: as Bruguera of flesh and blood bruguerahis films were simple in the form, but corrosive in what was navigating below. The costumbrista typology, the Spanish scenarios, the explosive humor: key was its style, for example, to strengthen what was known as’Landism‘, pure Hispanic anthropology with the best comedy deals of the time. Great successes. In addition to the films with Alfredo Landa, without a doubt his greatest successes were the ones he signed at the service of Andrés Pajares and Fernando Esteso. With them he signed the legendary ‘Los Bingueros’, sociological phenomenon and more grossing film of that year in Spain, but also ‘The Energy’, ‘Los Liantes’ or ‘Father there are nothing more than two’, up to a total of nine. The 96 films of his vast filmography They were seen for about 90 million viewers. He was the authentic author of the Spanish commercial cinema, when those things made no sense in our industry. Fast, quickly. In 1980, Pajares, Esteso and Ozores had collaborated three times: ‘Los Bingueros’ took the cinema to million and a half spectators and their immediate continuation, ‘The Energy’, of that same year, also went from one million audiences. In both cases they were very short -term films, as usual in the cinema invoiced at infernal speed at the time: ‘Los Bingueros’ was shot taking advantage of the legalization of bingos in Spain; ‘The energy’ was inspired by A nuclear accident in Pennsylvania that horrified the world. The following, take advantage of the international success of ‘Rocky’ in 1976 and ‘Rocky II’ in 1979. Roque III, our Rocky. In just twenty days, Esteso, Pajares and Ozores have their parody, ‘I did Roque III’, where Pajares gives life to Roque Third, a sparrow who lives at a friend’s house, a former Jockey come less. To remove it from Enmedio, the friend decides to take advantage of Roque’s past as an amateur boxer and convinces him to face the national welter champion, Kid Botija. By the way, this boxer named Mortadeliano gives life nothing less than Dum Dum Pacheco, champion of the time whose life, between excesses, fame and prisons, gives for several chronicles and It is currently claiming. Darth Vader reculates. The journalist Juan Sanguino tells it in the documentary ‘Pajares & Cía‘: The power of Pajares and Esteso at a box office to Fox, who decide to delay the premiere of’ The Empire counterattack ‘on the planned date, so as not to coincide with’ I made Roque III ‘. This premieres on September 19, 1980 and the ‘Star Wars’ movie, October 3. “They were the real phenomenon, the real Blockbuster“Sanguino says. Ozores can boast of being the only Spanish filmmaker who has bent to the almighty franchise.

We knew that the space spheres were at some point in the universe. We have a new theory about its origin

by

The universe is full of spherical objects: stars, planets, black holes and a part of the satellites that we can find in our environment have more or less round shapes. However, there are other types of spheres (or rather other types), spheres that are not formed of compact matter but whose circular nature can be captured by our instruments. Teleios. A few days ago, an international team led by researchers at the Western Sydney University announced The discovery of a unique object spherical located in our own galaxy. Although the main hypothesis about the origin of this object is in the outbreak of an IA type supernova, the team admitted that some pieces did not fit. This leaves the door open to different possibilities. One of the details we know about this object is that it can be detected “almost exclusively” in radio frequencies, something not so conventional in this type of objects. This and other details of the discovery make the object an immense enigma. An enigma that does not even escape its location. The problem of distance. We know that this sphere is found at a not very large distance from our solar system, inside the Milky Way. The problem is that the team responsible for its study has only been able to delimit two possible distances to which the object could be found: either at around 7,175 years-years of us, or about 25,114 light years of our location. This has an obvious involvement and we don’t know what size this sphere is either. If we assume that it is located at the closest point, its size would be about 45.7 light years in diameter. However, it could also be further and be larger: it would be more than 156.6 light years of length if it was found in the farthest location contemplated. Unknown age. The size is in turn a temporary implication. Being an explosion, the object would have formed from inside out, as an expansive wave. That is, if the radius of this explosion is longer, we would be facing a burst occurred longer than if we were watching a shorter radius. The team’s estimates indicate that, if located at the closest point, the supernova that this remnant would have left would have been given less than one millennium; While if it was about the location, we would be talking about an event that occurred more than 10,000 years ago. The problem of X -rays. One of the enigmas that surrounds Teleios has to do with the X -rays or, rather, with the absence of these. The models used by the equipment suggest that the remnants of a supernova as the detected should emit radiation not only in radio frequencies but also in X -rays. IAX type supernovae. The fact that this is not the case has led the team to raise a somewhat different hypothesis: that it is not the remnants of a Ia supernova but of a IAX type. The IAX supernovas are a subtype of the former. The IA Supernovas occur in binary systems dominated by a white dwarf star that absorbs the subject of its companion star until reaching a critical mass that leads it to explode. The explosions of this type of supernovas are very predictable: as they always explode when reaching the same critical conditions, these supernovas shine with a predictable intensity. But not always: There are cases in which the outbreak is lower speed and luminosity. Something that makes these supernovae unique is that they leave behind a important remnanta “zombie star” that we cannot find in conventional supernovae. This hypothesis however poses another problem, and for this to be the case, Teleios would have to be much closer to our planet than the estimates of the team itself posed. As noted, none of the hypotheses raised can answer all the issues raised by this enigmatic object, so more observations will be necessary and determine exactly what we have in front. Askap. The finding of G305.4–2.2, another designation for teleIos, was made in the context of the creation of the evolutionary map of the universe or EMU (Evolutionary Map of the Universe), A work done by the Askap Observatory (Australian Square Kilometre Array Pathfinder). The team recently sent an article to the magazine Publications of the Astronomical Society of Australia detailing the details of the finding. The drafteven under review, it can be consulted through the repository Arxiv. ORCS. In recent years it has been done relatively common Topar with strange circular objects with a certain resemblance to teleIos. Some of these objects are usually classified as a strange circle of radio or orcs (Odd Radio Circles), A name that already accounts for the strangeness they generate in astronomers. These circles usually occur in the Intergalactic space So the scale in which they are given is different from that of Teleios. Initially cataloged as Supernovas, these circles still consider an important enigma for astronomers. In Xataka | We have a new explanation for dark matter.

Aemet is clear that the end of May will not be “normal.” And the question is whether summer will arrive at some point

by

We were going to suffer the first summer bars and, although the calima has punctured expectations a bitthe truth is that heat and dryness They have been the great protagonists of the meteorology of most of the country. And I say most because in the northwest the storms are already being noticed: the next few hours, a new Dana will cross the peninsula leaving showers, storms and heavy rains throughout the country. It’s just the beginning. Things are going to change and we have been listening to it weeks; But the truth is that, for now, The situation remains the same. A meteorological combo. Because yes, the first thing will be a Dana that will sweep us from the Peninsular North and will leave Tuesday night towards France; But, then (between Thursday and Friday) a trough will affect the Mediterranean area. And, as I say, Everything seems to point to that it takes and daca It is not the end of spring During the next few days, days full of strong storms with more stable days will be happening. What is clear is that, we want or not, It will not be the normal situation For the last half of May. The best example will be the weekend. Because once the trough, stability will take over the country. The question asked everyone (meteorologists included) is whether it is the definitive one. Luckily, medium/long -term trends are here. And, for the first time in a long time, they begin to Draw a “return to normal”. European models point out that, although most of the Peninsula will receive average rainfall (and the north, a little more than normal), the southeast of the country must prepare to forget what has happened during this spring: the driest climate is here again. In fact, that is the second half of May. If we look at the first half of June, that climate “slightly dry than normal” will be present throughout the southern half, the Mediterranean coast, the Balearic Islands and the Canary Islands. The northwest quadrant will have a rainfall regime “within normal.” Something similar We will see with temperatures: During these two weeks, the fresco will endure in some zoans of the interior, but progressively all of Spain will slide towards a warmer situation than normal. Not too much, it is true: but enough to break the very long streak of strange patterns that began in March this year. Will summer start? It is a great question. The problem is that we do not know.

We are in 2025 and the Wi -Fi of the airplanes is still terrible. Starlink is demonstrating that we are at the turning point

by

June 30, 2016. BBC publishes an article called: How does the Wi -Fi work in the airplanes and why is it so bad? Almost 10 years later, we are almost in the same place. The Earth has revolved for almost a decade but in terms of connecting to Internet networks from the air it seems that we are completely stagnant. Or it seemed. 2016. “Some compare their speed with that of the beginning of the Internet, when, with the soundtrack of the atrocious beep of the modem, they had to be put on patience while any page was loaded.” With this paragraph Yolanda Valery for BBC In 2016 what was the experience of trying to connect to the Internet from the air. In that same article it was explained that connecting to the Internet from a flight guaranteed a certain guarantee to do very basic connected tasks, such as sending an email. But it was also mentioned that you could already forget to see a content in streaming Or, at least, assume that it was going to be a really tedious experience. We remain the same. In 2016, the offer of a wifi on board was relatively recent. In 2013 we told you that Iberia made this service available to the client at a price of five euros … for five megas. Shortly after, Enrique Dans narrated his experience In an Iberia plane and pointed out that the option was really interesting but that the result was very bad. And even raised if he had to be offered under the conditions of that time. Already in 2017, in Xataka We wondered why we still have no wifi in all airplanes. And we could say the same right now, with a good handful of airplanes that do not offer it … and above all: those who offer it and serve little or nothing. If we enter On Iberia’s own page We verify that in its reference to the connection packages it is specified that allow “Internet navigation, messenger, email, download and sending documents”. That is, tasks that require poor discharge speed. And they emphasize that it is “it is possible that during some moments of the trip the signal can come weakened” or that it lends itself with “three different suppliers, so you can experience differences between one flight or another.” Why is it so bad? The main reason why the Wi -Fi in the airplanes is so bad is how the Internet connection is obtained. You can take “global, satellite or land coverage,” depending on the flight, they point out on the Iberia website. This means that the plane receiver can connect to telephone antennas or satellites if the latter are not available. On a transatlantic flight, that connection is more unstable since Terrestrial antennas are far away. It only remains to be connected to a satellite so that the shipment and reception of data is complicated. First because the distance is much broader than when we have our feet on the floor and, second, because the plane moves hundreds of kilometers per hour, which complicates the reception and sending of the data. The big problem is that although the bandwidths that users have to share are now the demands of applications. Not only is the Quality of the images we load on Instagramis also the huge amount of data that an application like Netflix needs to play your streaming videos. Already in 2020, in Xataka We estimated that one hour sailing on this platform consumes between one and seven GB (depending on quality). A turning point? Andrew J. Hawkins explains in The Verge that the time may have come to say goodbye to these connections. In the aforementioned article, it indicates its experience aboard an E-175 Embraer, a 88-seat narrow fuselage plane that United Airlines uses for short flights. This, specifically, lasted 90 minutes. The plane is one of the first connected to Starlink and, in fact, will begin offering on May 15. The figures collected are highly hopeful. Connected to the airport Wi -Fi, Hawkins said navigating with a 305 Mbps discharge and a load of 249. The latency was 5 ms. During the flight, the speed was 196 Mbps of discharge and 27.3 Mbps of load with a latency of 19 ms. The discharge speed is close to the experience before climbing to the plane and although the figures are remote from what it offers on land, they are notable compared to those we had so far. During the whole flight. Hawkins breaks another spear in favor of the system and United Airlines: the wifi was active throughout the flight. “The service works from the door to the door, not only above 10,000 feet, restriction under which some other systems operate. As soon as I sat, they told me to connect to the Wi-Fi using United mobile application. “ In fact, in your article to The VergeThe author reflects the speeds during takeoff (234.8 Mbps of discharge and 14.9 Mbps of load with a latency of 19 ms) and the landing (72.6 Mbps of discharge, 26.1 Mbps of load and 90 ms of latency) when the worst data was collected. The time, despite this, would be brief because as soon as the plane touched earth again offered good figures with 231.5 Mbps of discharge. Although, this time, with the worst load data with only 3.01. Well to watch movies. But not so much to work. Because Hawking himself points out that he could use Instagram and Tiktok, Disney Plus, follow the ceremony of the new Pope for CNN or watch a live match “with a crystalline image quality.” However, the result was much less impressive when loading a file on Google Drive that took him seven minutes. Explains that this is because Starlink’s own infrastructure It is designed to download content and not so much to raise it, hence the difference in figures between the two processes. Differential.

Of course ‘the Simpsons’ also predicted the great blackout of Spain. At this point you have stopped having merit

by

Any relevant event in the history of humanity in recent decades It has previously appeared in ‘The Simpsons’. It is a phrase made, almost a meme that has acquired the category of popular wisdom and that is counted between the oldest collective knowledge samples of the digital era. Of course, Monday’s blackout in Spain and Portugal has become part of the long list of ‘The Simpsons’ predictions: it is neither very tight nor very accurate, but that does not prevent the myth from continuing to fatter. The blackout in ‘The Simpsons’. A couple of episodes that make supposed reference to the Backman last Monday. In ‘The last day of Springfield’, issued in 1998the city runs out of light, with traffic lights and unusable phones, and the nuclear plant where Homer works. Of course, chaos and anarchy take over the streets, something that did not happen here. Besides, In 2023 it was issued The episode ‘How beautiful is to pipify it’, where Springfield suffers a blackout for a fire in the nuclear plant. Here the consequences are almost apocalyptic, and Lisa tells the story in the distant future, explaining that the city lights candles every year to commemorate the events. The explanation of the prophecy. Either simple: These two blackouts do not make any reference to Spain or to the date on which it occurred. Simply, they are blackheads that end up leading to the Apocalypse, a trope of science fiction that have exploited recent series such as ‘Blackout’ or ‘The collapse’, or the movie ‘Leave the world behind’, but which we have also seen in very previous films: ‘The domino effect’ is one of the most notorious, but there are also based on real blackouts, such as ‘Blackout in New York’ or ‘Summer of Sam’ of which the American city suffered in 1977. Why ‘The Simpsons’ always succeed. According to Matt SelmanExecutive producer of the series, it is a mixture of knowing how to use the probabilities, historical knowledge and the study of human trends. The scriptwriters investigate in the past and extrapolate, until they end up. Or in another way more simpsonian, study and satirize “the stupidities of the past” to anticipate their repetition. They are logical extrapolations to which the impressive longevity of the series is added, which only multiply the possibility of coincidences, which is known as “Large numbers law“: The more episodes there is, the more likely the apparently unlikely becomes. When the phenomenon began. The meme began to popularize in the middle of the first decade of this century. Without a doubt, the first great impact of the series was the alleged prediction of the attacks of the Twin Towers. It was in the episode of 1997 ‘New York City vs. Homer Simpson ‘, where a brochure with number 9 appears and the twin towers forming a 11. It was interpreted as a reference to 11-S, although The explanation is very simple: The two towers together resemble a 11, the chance is that the attacks were on that date, and not to guess ‘The Simpsons’. Predictions for all tastes. Since then, ‘The Simpsons’ have predicted the future, and the truth is that sometimes the coincidences are stupid. In season 11, for example, the presidency of Donald Trump was mentioned, and in 10, the purchase of Fox by Disney (clear examples that the predictions are possible if an acute satirist observes carefully observes the signs that the current one sends). The complete list is virtually infinite: smartwatchesthe video calls, the performance of Lady Gaga in the Super Bowl, the Higgs Boson formula (amazingly close to the real), the three -eyed fish in the contaminated waters of Springfield, and a highly contagious epidemic that begins in Asia. We want fictions to explain it to us. We already told it A collation of the ‘Blackout’ series and how your search has become a trend after the real blackout: our thought is structured to look for significant patterns and connections between facts, even when these are the result of chance. These patterns help us explain what we do not understand or the phenomena that are rationally inconceivable or surpass us, and are marked by narratives, series and movies. And that ‘The Simpsons’ anticipate incomprehensible phenomena (such as the 11-S attack or Donald Trump’s triumph) helps us to rationalize them.

Someone has found a satellite for the first time on Google Maps. All tracks point to a Starlink satellite

by

There are people who spend hours exploring the most remote corners of the planet in the satellite photos of Google Maps, looking for surprising findings. But this time the surprise was not on earth, but in space. It is not a plane, it is a satellite. It is easy to find airplanes on Google Maps or Google Earth. Every day they fly between 100,000 and 120,000 planes worldwide. Not even poachers, such as bomber B-2, are safe from the satellite cameras that nourish Google maps with their images. The B-2 He was hunted in full flight A few years ago. But the bet has just risen with the most recent finding of A REDDIT user In coordinates 33 ° 44’39.0 “N 96 ° 44’46.2” W.: A rural Texas area, north of the city of Dallas. It is a satellite orbiting the land more than 27,000 kilometers per hour, which leaves the military plane at the height of a snail. Five colored spectra. The photo was taken on November 30, 2024 by a Pleiades European observation satellite, developed by Airbus. It is a picture that perhaps would have gone unnoticed if it were not for the five silhouettes of different colors that seem to be ghosts of the same satellite. It is actually the same satellite seen in five spectral bands. The black silhouette, captured first, is the satellite seen in the near infrared. They are followed by the red silhouette, the blue silhouette and the green silhouette, each captured with a different color filter in an instant infinitesimally different. Finally, the most clear silhouette of all, a pancromatic image of the satellite. The five satellite spectra on Google Maps Why do you look like this? It is a visual representation of two different phenomena: how quickly the objects move in the land low orbit, and how the observation satellites take their photos. They do not take a single photo, but several catches in different spectral bands (nearby infrared, red, blue, green and a pancromatic image on gray scale). Next, these images are combine with a Pansharpening algorithm To create a full color photo. Normally from the ground, which is still with respect to the satellite. However, this satellite moved almost eight kilometers per second, which caused the camera to capture it at five different points in the very brief moment in which the capture occurred. A Starlink satellite. Both Reddit users Like astrophysic Jonathan McDowell They believe it is a Spacex Starlink satellite. Unlike the first generation Starlink (which had a single solar panel), the V2 Mini have two large lateral solar panels that give them a wingspan of about 30 meters. According to McDowell, presumably is the Starlink 31147. It is not strange that the first satellite that has been found in Google Maps is a Starlink. Most satellites travel above 500 km so as not to have the atmospheric braking compensate, friction with the air that makes them end up resenting in the atmosphere. But the Starlink are launched at this point to offer a Global Low Latency Internet coverageassuming that will have to be replaced Every five years. 7,200 and up. Today there is about 7,200 Starlink satellites Orbiting the Earth (more than all the other constellations of combined satellites), thanks to Spacex’s ability to land the propellers of their rockets. That is why the investigations pointed from the beginning to Google Maps was a Starlink. Since Spacex has plans for Grow your network to a megaconstellation of 30,000 satellitesmost likely this is not the last Starlink that appears on Google Maps and other satellite photos, in the same way that it is increasingly common to see them in the night sky when we raise the view from below.

The doors of green hydrogen from Spain have found its starting point: the Basque Country

by

While Spain account With several hot green hydrogen points, infrastructure for distribution, such as H2Med, still Keep in development. However, the Basque Country has emerged as a new channel. Short. The H2BIDEA project, coordinated by Nortegas, aims to boost the development of a pure hydrogen distribution network in the Basque Country. The initiative will have the aid of the company Tubos gathered, in charge of creating the special tubes where high pressure hydrogen (160 bar) will be transported. A great initiative. Through a consortium of Basque companies, H2bidea It is cemented The pillars for the Basque Corridor of Hydrogen (BH2C). With this corridor they seek to establish an interconnected green hydrogen infrastructure that facilitates its transport and distribution, both regional and European. In three years, H2BIDEA hopes to have a distribution network demonstrator called H2TESTLAB, which will allow evaluating the efficacy of the installed infrastructure, according to has had notic access from Álava. Mass support. The project has the support of the Basque Government and the European Union, as well as with the collaboration of the Basque Companies Consortium, such as Arizaga, Bastarrica and Company (ABC Compressors), Orkli, Commercial of Electronic Applications (FIDEGAS) and Calcinor Servicios. It is not the only one. Because Spain continues to advance in the creation of more projects, such as the Mediterranean corridor (H2Med). This development initiative intends to interconnect Spain, France and Portugal by 2030 in what will be the first European hydrogen infrastructure. However, in recent weeks, has faced a controversy In Zamora on the use of water in the production of green hydrogen. More challenges at European level. A recent study by West Wood Energy consultant has estimated that only 17% of green hydrogen projects in the continent will materialize within five years. In that context, According to a Global Energy Monitor reportEurope faces difficulties to fulfill its decarbonization strategy due to the shortage of hydrogen produced in a renewable way. The limited amount of available green hydrogen and the slow progress of the announced projects question the viability of the energy transition plans of the continent. From another perspective. The Basque Corridor is an initiative that has emerged as a strategic point for the production and export of green hydrogen. In this way, it joins the ambitious plans of Spain to become a European green hydrogen leader. In fact, recently, the Spanish nation launched A hydrogen project with an investment of 1,214 million euros from the NextGneu funds.

To US controls are now joined by the Beijing himself, and point to his star chip

by

Nvidia has been dealing with the export controls that restrict the sending of their most advanced chips to China. But now, the company directed by Jensen Huang faces a double pressure: while trying to dodge Washington’s measures, it must also face new barriers imposed by Beijing, which threaten to further reduce their margin of maneuver in one of its key markets. A growing threat. As we said, the challenges for Nvidia are not new. In 2022, Joe Biden administration prohibited export of his chips A100 and H100specifically designed for artificial intelligence tasks. The company then warned that the measure could be up to 400 million dollars in sales losses in China. The answer soon: he decided to move. Thus, Nvidia designed a product designed exclusively to keep present in the Chinese market. To achieve this, he had no choice but to reduce the capacities of his chips and adapt them to regulatory demands. From there the A800 and H800 were born, cut versions of their star models. For a time they managed to be marketed in China, but a second round of controls ended up leaving them out of play. The H20 also wobbles. Once again, the team led by Jensen Huang got down to work to develop a chip adapted to the Chinese market. The result was the H20a cut version in front of its equivalents in the West, but raised as its great bet for China. Sales forecasts in 2024 exceeded one million units. However, obstacles have not taken long to appear. Now the pressures come from Beijing. Last year, the Chinese government began to recommend to local businesses to acquire NVIDIA GPUS. In full global career for artificial intelligence, the measure seemed contradictory. But the context explains it: just then, several Chinese manufacturers were finalizing their own alternatives to reinforce the country’s computation capacity without depending on foreign technology. Huawei has not stayed with crossed hands. The company has opted strong with products such as the Ascend 910C, a chip that, as points out Tom’s hardwarereaches inference to inference about 60% of the NVIDIA H100 yield. In addition, it is optimized for large language models and has already begun to be adopted by Chinese giants such as Baidu or Bytedance. Huawei also has other variants, such as the Ascend 910b. But there is more. In the middle of last year, The Chinese government presented an action plan to boost the “ecological development of data centers.” The objective was clear: to improve its energy efficiency. To measure the advances, the authorities chose a metric known as Pue (Power Usage Effectiveness)which relates the total energy consumption of the center – including air conditioning, lighting and other auxiliary systems – with the energy used exclusively by IT equipment, such as servers, networks or GPU. The objective of the plan was to reduce the can of the data centers below 1.5 by 2025. It should be remembered that the more the Pue can the value 1, the more efficient the data center is. One of the keys to achieve this goes to use more efficient graphics cards, which generate less heat and, therefore, reduce the energy consumption of the cooling system. The problem, As the Financial Times points outis that H20 chips do not finish fit in this equation. According to the aforementioned newspaper, the National Development and Reform Commission is urging local companies to use only chips that meet demanding energy efficiency standards, both in new data centers and in extending of the existing ones. In practice, this translates into increasing pressure on Chinese technology to reduce – or directly abandon – their GPUS dependency manufactured in the United States. For now, the regulations do not apply strictly, but everything indicates that that could change. In the horizon a possible hardening of control appears: inspections in situ, economic sanctions and harder requirements. If that scenario materializes, Nvidia could be seen before an even greater blow in which, until now, it is its second most relevant market: China represents 13% of its global sales, with more than 17,000 million dollars in annual income.
