five perfect light computers to take class

There is very little for the return to school, so if you are looking for a good computer to take the institute or university (provided they are allowed to take them) or to study at home or in the library, we have reviewed a review of Five laptops focusing on its size, weight and price. In addition, to avoid any mess with the software, all computers come with Macos or Windows operating system. MacBook Air M4 by 999 eurosone of the best proposals both for its size and for its weight, power and price. LG Gram by 868.99 eurosan alternative to the MacBook that includes artificial intelligence functions and a good battery. Asus Zenbook 14 by 999 eurosa laptop with OLED screen and artificial intelligence functions. Lenovo Yoga 7 by 749 eurosa laptop convertible OLED touch screen. Samsung Galaxy Book4 Pro by 801.51 eurosan ultrafine laptop with good processor. MacBook Air M4 Like more or less the macos operating system, the truth is that the MacBook Air M4 It is one of the best laptops to study thanks to its size, weight, power and price. By 999 euroswe talk about a 13.6 -inch laptop that weighs only 1.24 kg. Includes the M4 chip which offers both good power and performance and compatibility with Apple Intelligence. In addition, one of its strengths is that its battery has a Autonomy of up to 18 hoursthat nothing is wrong with forgetting the charger. MacBook Air M4 (16 GB, 256 GB) * Some price may have changed from the last review LG Gram As an alternative with Windows, the LG Gram He is also an interesting computer for the school. It can be found in the 14Z90ru configuration by 868.99 euros and stands out mainly because it includes a 14 -inch screen, Weigh only 999 grams and its theoretical autonomy is up to 24.5 hours (in practice it is lower). It also incorporates the Intel Core I5-1334U processor and comes with artificial intelligence functions through Co-Co-nursing.

OpenAI is already generating GDP size benefits from a small country. Follow light years of being profitable

Winning 12,000 million dollars a year seems somewhat prodigious for any company, but not when that company is called Openai. The evolution of income is being remarkablewithout a doubt, but both her and others – and here Anthropic is another good example – something serious happens to them: that they continue to spend more than they win. 12,000 million for OpenAi in 2025. As indicated In The Informationa new estimate that Openai’s “annualized” revenues will be 12,000 million dollars in 2025. The figure is a projection, but it is significant taking into account that in 2024 the estimated revenues were according to various sources of 3.7 billion dollars, although In Reuters They talked about the fact that they had actually reached 5.5 billion dollars. And 4,000 for Anthropic. The same media also recently indicated how the estimate in the case of one of its great rivals, Anthropic, has also risen and now It is 4,000 million dollars. Just two months ago that figure had already been checked and was 3,000 million, which means one thing: both are growing in number of subscribers. 700 million “Chatgpteros”. Another of the data to which the information article points out refers to the number of weekly active users. According to their data, 700 million people use chatgpt at some point in the week, which marks a unique milestone for the company. It is true that the vast majority of them are users of the free version, but that base is what allows part of those who use the service for free They end up pointing out to any of the chatgpt subscription plans. Income growth is being unusual in OpenAi and Anthropic, but both companies are spending absolute fortunes to end up being profitable. Source: Reddit. It will win 12,000 million, how much will it spend? In Reuters indicate that the internal estimates of the company also point to higher expenses. According to those projections, OpenAI will spend 8,000 million dollars, but that figure is dentra on direct operational expenses. There are many more associated expenses – investments, infrastructure, other financial obligations – and that makes OpenAi not profitable for now. We do not have estimated spending data for Anthropic, but it has an identical problem: Spend more than you earn. Spectacular, but. Although this growth in income is certainly extraordinary, it must be taken into account that to achieve this, these companies carry “Burning money” for years. The investment rounds that Anthropic and especially OpenAi have captured have allowed them to have a lot of room for maneuver to lose huge amounts of money without that at the moment that worries too much. And they will continue to spend as possess. Especially in the case of Openai, which thanks to SoftBank support It has great plans that will make it necessary to spend true fortunes. They have done it to Buy the Jony Ive design study for 6,500 million dollars, but above all they will do it with the project Stargatewhich still seems like very difficult to complete. But no profitability until 2029. Those responsible for OpenAi do not seem too worried, and we knew what the company’s financial road map was known weeks. They will continue losing money until 2029when supposedly – all is a free estimate, not a promise – will earn 100,000 million dollars. It will be then when the company will begin to be really profitable, but again, All this is a promise (or maybe a hope). It could not perfectly be fulfilled … and even ending up falling short.

WhatsApp finally has a quick and light application in Windows. Joy will last little

Meta launched WhatsApp for Windows and Macos In 2016. Since then, until 2022, the company had A slow and very little efficient customerfor a single reason: it was not a native application, but a web container based on WhatsApp Web, which implied slowness and enormous consumption of RAM. Better changes, changes worse. In 2022, WhatsApp on desktop made an praise leap forward, launching native messaging customers on both platforms and discarding the previous technology. According to Our own teststhe use of RAM in Windows went from 500 MB to 100 MB. The use of CPU making scroll, from 60 % to 20 %. Three years later, one step back, according to Windows Latest: WhatsApp beta (downloadable here) It is no longer native, it is a web container again that camouflages a browser. WhatsApp tricks and tips to hide you to the fullest and maintain your privacy Bad news. According to Windows Latest observations, made by analyzing the WhatsApp Beta processes in Windows Task Manager, Meta is using WebView2a technology that allows using the Microsoft engine within applications. Your own version of Framework Electrona standard in the industry. The bad news for the user in front of the application has nothing to do with using WebView2 in particular, but with abandoning the previous approach. This inefficient will be the new WhatsApp in Windows.Every time we open the new version, the application will have to load the web version internally, and in the background, an instance of the Microsoft Edge browser, on which Webview2 operates. Just as it happened with the version they developed from 2016 to 2022. It is very inefficient with respect to an application that uses Native Windows development platforms, such as UWP (Winui). In the absence of being able to prove it, Windows Delast tests demonstrate the step back, and are related to those made in Xataka in 2022. The new version of WhatsApp Web consumes 30% more of RAM than the version available until today in the Windows application store. It is a developing version that can be optimized more, but leaving the native approach has inevitable negative consequences. In Reddit Han accomplished that the new client consumes up to 1 GB of RAM. Goal explains why a native application is more efficient. When they launched the current client, goal created a website in which they explain the Benefits of a native application very clearly: “They provide greater performance and reliability, more ways of collaborating and functions that improve your productivity” “They are designed and optimized for your computer operating system” “They offer greater reliability and speed” Why use web apps instead of native. Being so clear the advantages of a native development, and even being defended by goal, why go back? The industry resorts to web -based applications for a very simple reason: unify developments and guarantee functions and compatibility parity between different operating systems. If a company builds a single website, you can easily adapt it to Windows, Macos, Windows, Linux and Android, as well as offer it in browsers. Optimization is sacrificed, but the deadlines are expedited and the size of the equipment required to move forward and maintain a project is reduced. Mark Zuckerberg himself said that IOS’s old Facebook app was bad because it was based on html. They went to native development and everything improved. The same In Android.

Some astronomers analyzed the “Big Bang sound.” Now they believe that the Earth is in a vacuum of 2,000 million light years

Cosmology has a huge problem. It is known as hubble tension and suggests that the nearby universe is expanding faster than the distant and primitive universe He is telling us. Something does not fit. Now, a disturbing study offers a solution. The big problem of cosmology. Hubble tension is One of the biggest headaches of modern physics. On the one hand, we have the measurements of the cosmic microwave background (CMB), the oldest light in the universe. When applying the standard cosmological model (LBDACDM), these observations show a 67.4 km/s/mpc hubble constant. On the other hand, when The expansion of the universe is measured Using nearby objects such as standard candles (a type of supernova), a significantly higher value is obtained: about 73 km/s/mpc. This difference, that the most recent data places in a tension of more than 5Sigma (a level that in particle physics is considered a discovery), refuses to disappear. A disturbing explanation. A new study Prepublished in Arxiv proposes a solution as elegant as depressing. That the discrepancy is not in our measurements, but in our location. According to Indranil Cosmologists Banik and Vasileios Kalaitzidis, we could be living in the center of a gigantic cosmic vacuum, a “bubble” of 2,000 million light years in diameter with a density 20% lower than the universal average. The test, they affirm, It is in the “Big Bang sound”. A local vacuum. The idea of the local vacuum is not new: it is known as the empty KBC (Keenan-Barger-Cowie, in honor of the astronomers who proposed the idea based on the galaxies count). If our galaxy, the Milky Way, were in a region with less matter than normal, the severity of the surrounding, densest areas, would “throw away” out. This effect, added to the general expansion of the universe, would cause nearby galaxies to move away from us faster than normal. “This would give the appearance of a faster local expansion rate,” explains Indranil Banik, of the New Research. The Hubble tension problem would thus become a local phenomenon, without the need to revolutionize the entire cosmological model. The sound of the Big Bang as proof. What the new study of Banik and Kalaitzidis contributes is a much more fundamental test based on barionic acoustic oscillations. Although we call them “the sound of the Big Bang”, they are not sound waves that we can hear. They are the traces that left the pressure waves that spread through the superdense plasma of the primitive universe. These waves were “frozen” about 380,000 years after the Big Bang and created A characteristic pattern in the distribution of matter. This pattern works as a cosmic rule of about 500 million light years in length, which astronomers use to measure the expansion of the universe to different eras. The results. The team analyzed 20 years of measurements and compared them with two scenarios: on the one hand, the homogeneous standard model, without emptiness; and on the other, the model that includes the empty KBC. The results, presented at the National Astronomy Meeting 2025 of the Astronomical Society Royal, are blunt. According to the statistical analysis of the study, the model with a local vacuum conforms to the data in a spectacularly better way. While the standard model has a 3.3sigma voltage with observations, vacuum models reduce it to only 1.1sigma –1.4sigma. Calmly. The researchers consider “demonstrated” that A vacuum model is about 100 million times more likely than a model without emptiness. However, it is a preliminary study, which has not yet gone through the pairs review. Previous studies set very strict limits to the existence of such an influential vacuum, concluding that it is not enough to explain the entire Hubble tension. They also propose early dark energy as a solution. But Banik’s work offers one of the strongest evidence to date that the Earth could be in a very lonely region of the universe.

The Spanish Galeon San José was sunk transporting 20,000 million dollars. Mexico and Colombia are going to bring that treasure to light

The history of San José Galeon It is very particular. The ship left the shipyards of Guipúzcoa in 1706 to the sea of ​​the Caribem, and there it was loaded to the flag with gold, gems and jewels from Peruvian, Bolivian and Mexican mines. It was a Awesome boat With 40 meters of length, 64 cannons and a crew of 600 people, but was sunk after an attack of British privateers in 1708, leaving only 10 survivors and that juicy treasure in the depths of the sea off the coast of Cartagena. It is one of the More than 1,500 Spanish Spanish ships Through the world and Mexico and Colombia are collaborating to ‘rescue’ those treasures that have been in the back of the ocean for more than 300 years. It has a value My dear of 20,000 million dollars and is the protagonist of an authentic soap opera. A soap opera. The history of San José did not end when the ship touched background. In fact, I may only start. In 1981, the Search Armed Exploration Company claimed to have located the Spanish wreck and delivered the coordinates Not Spain, but Colombia. The treatment? Supposedly, access to half of the treasure. However, in 2015, the Colombian government said they found the remains in a place different from that indicated above. That enraged the company Cazatesoros, who claimed that it was a strategy so that Colombia did not have to share the treasure. Neither short nor lazy, former president Juan Manuel Santos proudly said it was one of the most important treasures in Colombiaand everything pointed out that Search Armada would not see a cent. Meanwhile, Spain was not with crossed arms and appealed to his sovereignty about Galeon. Investigating. In 2024, with the wreck even in dispute, the Commission for the Investigation and Accusation of the House of Representatives of Colombia opened an investigation against former president Santos. The reason? “Intrusion and looting” of the Spanish Galeon. “It’s not a treasure”. The current Colombian government has another point of view and, in May last year, declared as the protected archaeological area the pungent area. The Minister of Cultures of Colombia, Juan David Correa, said that it was “the first time that an archaeological heritage area submerged at such depth is declared, it is historical for Latin America. We already have a special plan of underwater archaeological management.” Protection. The objective, then, is to guarantee the protection and conservation of the Galeon, as Alhena Caicedo, director of the Colombian Institute of Anthropology and History, and said history, and The doors were not closed to treat the wreck as shared heritage. The objective now is to see what the ship was transporting and catalog it. It seems that it is not a treasure rescue mission, such as Correa itself: “It is not an extraction mission for economic value. What we want is to leave Colombia the possibility of a scientific-cultural mission that will have several stages and that starts today.” Mosaic rebuilt from photogrammetry files Mexico + Colombia. And that is where the National Institute of Anthropology and History -INAH- of Mexico comes into play. In an initiative called “Towards the heart of the San José Galeon”, Colombian and Mexican researchers are collaborating to be able to carry out this ‘recovery’ process. Mexico has a great experience when making archaeological expeditions (with recent examples such as the entire Mayan train networkthe application of New techniques to explore the interior of pyramids and the Underground stay mapping). A underwater expedition is different, but there they also have something to say. Colombian researchers asked INAH members about their experience in the project of Our Lady of Juncala ship that shipwrecked in 1613 in the Gulf of Mexico and with which there are parallels in the case of the San José expedition. In addition, between Colombia and Mexico there are archaeologists support programs that are formed in a cross way in both countries, as if it were an Erasmus of archeology. Digitize everything. Therefore, Mexico is advising Colombia, but it is these who, using submarine robots, are exploring San José and its surroundings in a program consisting of four phases: First phase (it began in May 2024): an underwater research ship comes into play with dynamic and acoustic positioning technologies, as well as a remote operating vehicle with sensors that has the mission of reaching the site. Second phase: generation of images of the site with which to prepare a record of the archaeological evidence for the classification of materials and their origin. THIRD PHASE: prediagnosis of conservation to establish starting points on the level of deterioration of the elements. Fourth phase: Digital documenting the archaeological context through photogrammetry techniques for informative purposes. It seems that Colombia’s plans are clear and, according to the details of the different phases, it does not seem that the goal is to get everything they find out of the water, but to catalog it so that we can see the state of the ship and its shipment 300 years later (in addition to the wealth it carried when it was sunk). Next steps. These last weeks, however, There have been important findings. The ICANH confirmed new “areas of interest” on the site, with Chinese porcelain, ingots, weapons and currencies that allow us to know more about the context of the sunken galleon. In addition, both INAH and the Ministry of Culture of Colombia have set October 2025 and the date on which they will detail the next steps of the mission. The idea is to profile that strategy of ‘towards the heart of the Galeon’ in order to exhibit tangible results before the end of the current presidential mandate in 2026. And, surely, it will be then when the controversy between Spain, Colombia, the indigenous community Qhara Qhara that demands Rights on the Treasury and the company that claims to have discovered the wreck to a new level.

If Europe is beating solar energy records this summer, why has the price of light shot?

Summer is a paradox season for the energy sector. On the one hand, renewables are reaching historical figures. June marked the month of greater production of solar energy ever registered in the European Union: Friolera of 45 twh22% more than the previous year. On the other, many Europeans saw how their light of the light doubled or even tripled. The question is inevitable: if we swim in solar energy, why do we pay more for electricity? The demand is triggered. The heat waves that run Europe They have put the thermometers around 40 ºC in numerous points in Spain, France and Germany. With air conditioning systems, working at maximum power, the electrical demand has shot. According to him Last Ember reportdaily demand grew by 14% in Spain, 9% in France and 6% in Germany during the month of June. A greater electrical demand, alone, already presses the prices of upward light. But the heat brought with it a second problem, this time on the offer side. Thermal plants are suffocated. The same heat that drives the demand for air conditioning puts traditional energy plants, especially nuclear. These facilities need huge amounts of river water to refrigerate their reactors. When the water temperature rises too much, its refrigeration capacity decreases, forcing to reduce production and, in extreme cases, to stop it completely. France It has been the most affected country. Its fleet of nuclear centrals, one of the pillars of the European interconnected network, is suffering capacity reductions in almost all its facilities. But it is not an exclusively nuclear problem. In Poland, the cooling of coal centrals is being a constant concern, and in Italy, the overheating of the network cables was the most likely cause of the blackout of July 1. At the time of maximum need, a crucial part of the generation of traditional energy is not available. Missing storage for the solar. The saving of this crisis is photovoltaic solar energy. In Germany, the Solar came to generate 50 GW peaks, covering between 33% and 39% of the entire electricity of the country. With a marginal cost close to zero, solar panels are doing exactly what is expected of them: maintain the stability of the network during the day with abundant and cheap energy, despite their Performance problems under extreme heat. The night is another song. At sunset, solar production falls to zero, but the refrigeration demand remains high. When the high temperatures persist until well into the night, Insufficient storage capacity (either in batteries or With pumping hydroelectric) forces to resort to gas and other fossil sources to cover the hole, shooting prices. The damn “Spred”. This temporal mismatch caused by the abundance of variable energy and the lack of resources to store it is what causes madness in prices. A daily price differential (the “spred”) of up to € 400/MWh in Germany and € 470/MWh in Poland. This night peak, and not the average price, is what triggers the final bill and makes the light through the clouds when more cheap energy is producing. The lesson is clear: the challenge is not only to generate cheap renewable energy, but manage it. More storage is needed to buy energy at low prices at noon and sell it at high prices in the afternoon. But also More European interconnections. The heat wave did not affect all of Europe with the same intensity and the same day. The biggest June peaks arrived in Madrid on Domingo, Paris on Tuesday and Berlin on Wednesday. The reinforcement of the interconnections will allow to distribute the cheap energy more and better.

Goal has just remembered why we should never give all our photos to a light app

I recognize that I am the type of person who, between allowing access to the entire photo reel or only a few, I usually choose the first, especially in apps that I use a lot as Instagram. Being able to access the entire reel and not having to take photo photo to photo is more comfortable. Total, if I don’t upload the photos, nobody can see them, right? It is not so clear. Meta wants the photos that we do not publish The news comes from Techcrunchwhere a few days ago they told how Facebook had begun to ask users for “cloud processing to obtain creative ideas made for you from your photo reel.” To create those ideas, They choose photos of the reel and upload them to their cloud. In addition, by accepting, he warns us that we also accept the terms and conditions of goal AI, which include the analysis of photos and videos, including the facial characteristics of everyone who appears in them. From The Vergethey contacted a goal to ask the question that you will surely be doing, and it is if they were using those unpublished photos To train your AI. Goal ensures that not currently, but They do not deny that they can do it in the future. Although for now this novelty only affects users of the United States, it could later reach more countries, so better to be prevented. Access yes, but better on accusagotas There are many apps that ask for access to our photos and videos and it is in our hand to decide whether we give them access or not. Both iOS and Android allow Choose what images we want to share with each app. In the case of iOS, it even reminds us periodically if we want to continue sharing our entire reel with certain apps. I am one of those who ignore warnings. Seeing cases like the goal I am clear to me that it is a bad idea. The option to limit access to photos in iOS (left) and Android (right). I have begun to limit access in apps that I use daily as Instagram and the truth is that It is not as tedious as I thought At first. When I want to upload something, I just have to give that something and that’s it. In the end it is to add another step, yes, but it is done quickly. If you want to do it you just have to go into adjustments and go to the app you want, for example Instagram and, within the gallery permission, choose ‘limited access’. The importance of the small print in the AI ​​era We take care with the photos and videos we share, but we do not think about what happens to everything we do not upload. It is normal, the logical thing is to think that, if you do not click on ‘Share’, no one except you can access that photo. This case shows the importance of reading the small print of apps, something that we are honest, very few people do. Maybe before it was not so worrying, but in the current context, with so many models, the thing changes. To train those models It takes a lot of content, very much. There has been Many controversies Around this: the use of Content protected with copyright, LinkedIn training its AI with user data almost without warning, AI models that draw platforms like Reddit And even others who train With photos of minors. If it was already convenient to be cautious, now much more. Image | Own in mockup of Freepik In Xataka | Spain wants to implement the “pajporte” for access to part of the Internet.

After the hottest June in the history of Spain, there is a minimum ray of light on the horizon: Vaguadas

The heat wave It comes to an end, although the high temperatures will fad down gradually between today and Thursday. The heat wave has been the culminating point of a series of warm episodes that have been repeated since the end of May and, like so many of these episodes, has seen its end with the arrival of a trough and important associated storms. A record heat. Meteorologists advance that the month of June has been the hottest since we have records. And that It is not the only record that has broken during the last 30 days. The absolute temperature record was also broken for a month of June. It happened in the Huelva municipality of El Granado, where the thermometers They got to register a maximum of 46º. As if this were not enough, June He has also pulverized Another record, that of the greatest positive thermal anomaly, 3rd Celsius above what would be common during the sixth month of the year. All that despite the fact that a month with marked meteorological fluctuations in which extreme heat episodes with brief but intense storm episodes have alternated. It has been the tonic of recent weeks and everything indicates that once again it will be the storms that free us (for now) of heat. Summer troughs. Thermal relief will arrive pushed by arrival Of a series of troughs, the extensions of a area of ​​low pressures that will bring us cold air and atmospheric instability. It is expected that the arrival of the cold air associated with these troughs interact with the stagnant warm air mass on the peninsula and part of southern Europe. Storms and hail. THE RESULT: A NEW STORM REMESTING AND THE POSSIBILITY OF HEGHOE TO CHARGE STEPORS. The appearance of convective winds (resulting from the presence of warm and humid air that ascends to high layers of the atmosphere) is one of the key factors in this context. And what do the forecasts say? The State Meteorology Agency (Aemet) foresee that during the next few days the heat (still extreme in many areas) coexist with the proliferation of “locally strong” storms. Today these storms are expected in the mountains of the northern third and this peninsular; While tomorrow the mountainous areas of the entire northern half and surrounding areas could reach, as well as at northern plateau points, half north of the South Plateau and Sierra Nevada. Uncertainty. It is still early to foresee the weather tendency of the month of July but seasonal forecasts Aemet does not call optimism. A few weeks ago the agency spoke of a high probability that the summer of 2025 be remarkably warmer than usual.

Taiwan believes having found the mythical planet 9 of the Solar System. Instead of looking for his light, he has been looking for his heat

The countless frustrated attempts to find planet 9, a hypothetical giant gas in the confines of our solar system, have aroused the ingenuity of some Taiwanese scientists. Short. For years, astronomers have swept the sky in search of the weak reflection of sunlight that should get to us from planet 9, a demonstratedly ineffective task. Now, a team of researchers has changed the rules of the game with an ingenious idea: instead of looking for it, they have tried to detect their heat. Well, they have found two very promising candidates. Context. Beyond the orbit of Neptune, in an icy and dark region known as the Kuiper belt, the orbits of several objects seem to be grouped in a way that challenges chance. The trajectories of these transneptunian objects (TNos) align as if an invisible hand were guiding them. The most accepted hypothesis to explain this behavior is the existence of an unknown massive planet, the planet 9. Of existing, this distant world would have a mass of between five and ten times that of the earth. The problem is that it would be more than 400 astronomical units, so its light would be incredibly dim. To put it in perspective, Neptune is “only” 30 UA or 4,496 million kilometers. If we can’t see it, maybe we can feel its heat. A team from the National University Tsing Hua in Taiwan believes to have the strongest track in years on the real existence of the most wanted object in our neighborhood. The results of their study are not final, but they reach two promising candidates. Every object with a temperature above absolute zero emits thermal radiation, that is, heat. But while the light decreases with the distance following a relationship of the inverse of the fourth power (1/d4), the heat only decreases with the square of the distance (1/d2). This abysmal difference is the argument used by researchers to focus their search on the heat signature of planet 9. A needle in a haystack. The team resorted to the data of the Akari Space Telescope of Japan. Throwed in 2006, Akari dedicated his useful life to sweeping the full sky in distant infrared light, the perfect range to detect the thermal brightness of the planet 9. And he did it from space, without the interference of the Earth’s atmosphere. Astronomers set out from a list of unprocessed Disssdl detections: more than 5.2 million signals with many false positives. After limiting the search zone, eliminating known objects, filtering sources contaminated by galactic dust clouds and excluding static objects, which seem to be at the same point in observations separated by months, the list was reduced to 393 candidates. Of 393 candidates for two. He touched his hands dirty. The investigators visually inspected the images of the 393 candidates. They ruled out weak detections, artifacts at the edges of the sensor and, above all, the impacts of cosmic rays that can be perceived as a specific source of heat. After this thorough process, there were only two candidates. Two heat points that appeared where planet 9 was expected, had the predicted brightness for the theory and showed the expected movement: they were detected in the same place in a period of 24 hours, but there was no trace of them in the same place six months later. All to demonstrate. The two candidates were baptized as FISSDL J0250422-15011 and FISSDL J0301112-164240. But to verify if these two heat points are really a single object moving in an orbit compatible with planet 9 will need new observations in visible light, with sufficiently powerful telescopes to detect its weak optical brightness and measure its movement with precision. If confirmed, the discovery would not only solve one of the greatest mysteries of modern astronomy, but would revolutionize our understanding about how our own system was formed and evolved.

The light of the light has risen a lot and the electric ones blame it for the blackout. Facua has something to say about it

May 2025 promised to be the cheapest month thanks to the renewable generation in spring. However, consumers They have ended up paying more In the light of the light for the blackout of April 28, since they have had to activate emergency mechanisms or reinforcement systems. Now it seems that that should not have been so high. Short. Facua-Consumnadores in Action has warned the electricity marketers of the free market, In a press releasethat they cannot raise their rates unilaterally for the blackout of April 28 if that change is not provided for in the contract. A specific case. The association has loaded directly against Energía, a commercialization of the Repsol Group that has notified a 6% surcharge (about 73 euros per year), alleging an “increase in technical costs of the system” for the electricity network reinforcement system. However, like He recalled Facuaadjustment services are not part of the regulated costs (such as tolls and charges) and, therefore, do not justify a rise in the price agreed in free market contracts. The law is clear. According to the Civil Code, contracts must be fulfilled as agreed and cannot be modified according to the will of a single part (Arts. 1256 and 1258). Exceptions would only be accepted if the contract explicitly includes a clause that allows the marketer to apply these increases by extraordinary situations such as the lived. From the other part. The employer who brings together Iberdrola, Endesa and EDP, AELEC, is pressing to distribute or contain the overrages derived from the blackout. Its proposal is to transfer these extraordinary expenses – given to operate the system in “reinforced mode” to avoid new blackouts – to other concepts of the invoice, such as regulated charges, where costs by renewable or extrapeninsular are also included, according to Finch access has had access. There are more. The employer has calculated that the reinforced security strategy has meant an extra cost of 200 million euros in just one month and requires that there be an extraordinary regulatory response, so that neither consumers nor marketers assume that impact alone. As has detailed Fifodies, are in search of a “transient and exceptional” measure that relies on operation procedures 8.2 and 14.4, already provided for in the current regulatory framework. So is it valid? Legally, the key point is the type of contract that each consumer has. In free market contracts, prices are agreed for a year and cannot be modified unless the contract expressly allows. If there is no clear and specific enabling clause, the climb would be illegal, and it could be considered an abusive clause, even if there is a notice. From Facua they support this thesis in the Civil Code and in Article 65 of Royal Legislative Decree 1/2007 on consumer defense, which establishes that contracts must be interpreted in favor of the user and according to the objective good faith. That is, although the company affirms that the surcharge is justified, if you did not sign it and is not in transparent conditions, it cannot impose it. Any forecast? Today, neither Red Eléctrica nor the Ministry for Ecological Transition have clarified how much this reinforced security operation will last, nor how its costs will be distributed. From AELEC and other associations, an intervention of the regulator or the Ministry to temporarily redesign the cost distribution is expected. The objective: avoid an irreversible impact on the electrical marketing market and contain the price escalation.
