It is more efficient to learn how your brain works

The ability to be productive is not only in the ability to make the most The available time. You can also improve that capacity by understanding some cognitive biases and “psychological triggers” of the brain to use them in your favor. Such and as they point out in Fast Companyyou don’t need more hours in the day. You need to adapt your work to match the cognitive peaks of your brain and “deceive it” to Maintain motivation. These are some cognitive strategies to be more productive with less effort. 1- tune in with your ultradian rhythms Unlike Circadian cycleswhich last 24 hours delimiting rest periods, Ultradian cycles They are much shorter and repeated every 90 or 120 minutes. The brain is Designed to work in cycles of high concentration limited to those periods between 90 and 120 minutesfollowed by small laps of lower energy. Trying to give the maximum beyond those cycles is a waste of time. The brain needs to rest To recover energy. Ignoring that rest makes mental fatigue appears, worsens concentration and, with it, stress increases because tasks are extended more than expected. The key is in Organize the day in blocks of deep work 90 minutes with pauses of 10 to 20 minutes between them. Implementing three of these daily cycles usually translates into greater productivity and better quality of the tasks performed. 2- The most difficult first Would you run an Ironman just after a marathon had run? Not to be That you are Verdelissthe most likely answer is not, because the first test has already burned all your energy. In this case, the brain works in a similar way. The prefrontal cortexresponsible for complex executive functions, shows its greatest efficiency in the early hours of the day when we have rested well. The key is think about your brain as a battery. Which is 100% at the beginning of the day, but little by little it reduces its load (cognitive capacity). Use that energy strategically. Take advantage of the first two or three hours of your day to address demanding or very creative tasks that will consume “more energy” or that require greater concentration. Administrative, routine tasks or those meetings in which relevant decisions should not be made, they can wait for later. Doing it backwards would be to waste that valuable energy throughout the day, to get exhausted to the marathon. 3- Sorry, the brain is not multitasking Although everything points to doing several things at once is the best way to advance them all, scientific research They have demonstrated That is not so. In fact, trying to do several things at once is even 40% less efficient What to do them one after another. According to a Published study in Nature By scientists at Stanford University, he points out that those who perform multiple tasks at the same time, often They get worse results in tests of attention, memory and alternation of tasks that those who perform only. Therefore, instead of trying to move all the tasks at the same time, it is convenient to make groups of similar short tasks and reserve blocks of time to complete them (one after another). Thus, small distractions are reduced that interrupt your concentration With the excuse of “it’s just a minute.” 4- Concentration triggers Although sometimes it costs us to recognize it, the human being It is an animal of customsand our brain is able to detect signals from the environment to prepare to face certain tasks. An example is the “cognitive triggers” described by James Clear, author of the best seller ‘Atomic habits‘, as a method To create habits. To give you an example, the way back to your house at the end of the work prepares your brain to enter a “rest mode”, in the same way as preparing a bath with candles and aromatic salts predisposes to entering a mental state of relaxation. Create fixed signals or rituals to immerse yourself in deep work, such as order the table Before starting it, putting certain music or systematically opening your task app, can help you make the brain entered the right state. The research From the University of California they demonstrated that these actions, apparently small and symbolic, act as psychological switches that tell your brain: “It’s time to concentrate.” The repetition of these habits reinforces the approach and reduces the adaptation time that the brain needs between one task and another. 5- The brain is not to remember A joint study of the University of Waterloo (Canada) and the University College London, says the Human working memoryIt can only handle between four and seven simultaneous elements. The research demonstrates that by downloading information, either In writing in a notebook or digitally In an apptension in the cognitive system is reduced and bandwidth for problem solving and creativity is released. To the free the brain from the burden of having to remember thingsthe Zeigarnik effect is avoided, a phenomenon that puts a name to the brain obsession to end The tasks that you have already started. If you have to remember, for example, that you have to go looking for a laundry jacket, your brain will be constantly recovering that information until you complete it, interrupting your concentration in that process. 6- A carrot for your brain Maintain motivationin addition to physical factors, it is also very conditioned by the brain. Again, our animal instinct responds to positive stimuli. As an ass that needs to follow an unattainable carrot to continue walking. The human brain reacts to immediate and visible rewardsso marking an objective as completed activates the Dopamine system that provides well -being and happiness. Taking that into account, Do not plan your tasks as long -term achievementsbut as small frequent achievements that activate the brain reward system. These frequent awards reinforce behavior and generate the impulse to continue with the project and avoid falling into boredom and loss of motivation.

Professional CEOs are a species in extinction. Who tries it does not repeat

“CEO is sought for a large company. Leadership capacity is valued and being able to work under pressure. Salary above the average.” If vacancies for the positions of the executive director of the large companies will be announced Like the rest of the positionsthey would probably be something similar to this. However, there are less and less “ceos to serir”, as they defined them In an article of The Wall Street Journal Two decades ago, referring to a lineage of executive directors capable of Change company Every four years, and even sector. The important thing is to direct. What does not matter so much. Ceos for everything. There was a time when the executive directors jumped from one company to another every four or five years. It was almost a mythical figure in the halls of global capitalism. These leaders, known as CEO in seriesthey were sought to lead deep transformations, implement aggressive cuts or save drifting companies. However, that figure is running out of generational relief. However, there are still some managers that fit into the classification of CEOs in series. Names like Luca de Meowho was head of Fiat and Alfa Romeo before becoming CEO of Renault, and is now emerging to lead the transformation of Kering, luxury fashion holding that markets marks such as Gucci, Balenciaga or Boucheron. Brian Niccolcurrent CEO of Starbucks, which had previously directed Chipotle and Taco Bell. Be CEO. Instead, such and as he points out he Financial Timesthe predominant model is the “One and Done”, in which many executive directors choose to occupy that position only once in their career, exhausted by pressure, extreme public exposure and wear that implies exercising the leadership of a large company today. The CEO of a British company quoted in the stock market reflected this feeling by declaring the Financial Times: “After this work, I will have finished. It is very rewarding, but it leaves you exhausted. I will never occupy the position of executive director ever again.” According to data From Russell Reynolds, in 2024 there were 220 changes in the dome of large companies in the main 13 global markets. Of these, in 187 cases (85%) were appointments of people who assumed the position of CEO for the first time. This phenomenon has accelerated since 2018 and highlights a substantial change in the criteria of choice of new CEO. As Laura Sanderson, director at Russell Reynolds, explains, “the decline of the CEO in series probably reflects the nature of the current position. It is high pressure, high risk and is very exposed. The path to a retirement with the intact reputation is complicated and, for many leaders, a single experience like CEO is sufficient.” Chiefs of the quarry. Given the shortage of profiles experienced in the direction of large companies, many companies have begun to invest in their internal talent quarries. He Ascent from other high positions of management as directors of operations, financial directors or area leaders has become a usual formula to ensure a less traumatic relief because Who ascends already knows the company. However, it is no longer enough to know the company and the sector in which it moves, but as it summarizes A study From Miltown Partners and The Chief of Staff Association, “today’s leaders have become executive directors who do everything, everywhere and at the same time.” The position now also requires other skills that the quarry managers cannot always offer: the advance of AI, the constant pressure of the shareholders, the political and cultural atmosphere. Any phrase out of place can become A reputational crisis for the company and even at a real risk for the manager, which can become target of attacks as was the case of the executive director of United Healthcare More difficult, more salary. The increase in the requirement of responsibility for executive directors has also been accompanied by A salary increase equivalent. He Average salary of the CEOs Of the large US companies reached 30.9 million dollars in 2024, which means “more than one fifth part of the average salary of 2023”, according to Indicates the study Made by Equila and Associated Press. However, neither money nor The extraordinary benefits have managed to stop the Trend to abandonment of the management positions. It is increasingly common for candidates to reject these positions if other companies have already directed before or if the conditions seem especially demanding. Power wears. Faced with this continuous stress situation suffered by the company’s first representative, a new form of early retirement is being imposed: that of the “portfolio race”. With this new modality, the Executive takes a step to the side as a visible face of the company, but remain linked to it taking advantage of its experience as an advisor or defending the interests of the company participating in the board of directors of third parties. An example would be Noel Quinn, who, after a prolific Race at the head of the Swiss Bank HSBChe decided to retire in 2024: “Now is the right time to achieve a better balance between my personal and business life,” explained after Assume the presidency of the Swiss bank Julius Baer.

There are skirts that go fast, there are scooters that are going very fast and then there are scooters like The Turbo: 160 km/h

What are all in common, absolutely all the electric scooters that any Spaniard can buy? That are limited, by law, at 25 km/h. It doesn’t matter if it is worth 200 or 1,500 euros, the scooter cannot pass that speed. That contrasts, of course, with what is capable of getting the fastest electric scooter in the world. Your name? Bo the Turbo. Your maximum speed? More than 160 km/h. Where does this come from? BO is a British company born in 2019 whose founders have advanced engineering experience in Formula 1. Roughly, BO is a company dedicated to electric scooters and its latest proposal is the Bo the Turbo, a conventional scooter on the outside but that, inside, has a double engine and a motor competition train “with a power-pepper ratio superior to that of the Bugatti Veyron“, according to the company. Bo the Turbo | Image: bo Excessive power. The device, because of scooters only has the form factor, has a power of up to 24,000W. For development, BO was associated with Rage Mechanics and applied the Safesteer stabilizer, his own technology, which basically assists the driver when he passes through a pothole or irregular surface. To stop, the scooter incorporates Hope V4 disc brakes With four front and rear pistons, as well as floating rotons so that the system does not warm more than the account in braking at high speed. And the result? This video surely speak by itself. Battery. A section that surely arches some eyebrow is that of autonomy. After all, a mamotreto like this moving at a tremendous speed surely endures little. According to the company, it is quite the opposite. It has a 1,800 WH battery, which translates into an autonomy of up to 240 kilometers. And for what? Needless to say, this scooter is not made for retail sale. It is a proof of concept, a demonstration of how far a single -person electrical mobility can go if technology is released. Putting a scooter 160 kilometers per hour is dangerous, even more on the street, so surely, to see it, we only see it in a circuit (where, everything is said, it has to be hilarious to pilot it). Bo the Turbo | Image: bo If someone wanted it, their price is $ 29,500, there are limited editions and is manufactured by order. Curious fact: The first unit will go to the house of a collector in Madrid. It will be there, precisely, the first units will be shown in the prelude to the Madrid Formula 1 Prize. However, it is not the fastest. Although the Bo The Turbo has brutal figures, the truth is that it is not the fastest electric scooter in the world. That title has, for now, The RM-X of precisely Rage Mechanics. This scooter has a power of 50,000W, reaches 173 km/Hy goes from 0 to 100 km/h in 4.5 seconds, always according to the brand. The fight against rapid scooters. These personal mobility devices They live a convulsive timeat least in our country, where they are increasingly limited. Not only can they not exceed 25 km/hbut they cannot go on the sidewalks and are prohibited from circulation in interurban roads, crossings, highways, highways or urban tunnels, the use of helmet, etc. is mandatory. As far as speed is concerned, it is no secret that there are methods to eliminate the limitations of some models. Without going any further, at the beginning of the year It was detected in Barcelona A trucado device that could move at 113 km/h. This can carry sanctions of up to 500 euros and the withdrawal of the vehicle.

The US hardened their restrictions for Nvidia chips not to reach China. So they are sweeping the black market

A few days ago Nvidia got what It seemed impossible: That the US government allowed you to sell your H20 GPU very soon to Chinese clients. It was an important turn in the Trump administration policy, which since April had raised his restrictions. Despite the hardness of the sanctions, the plan has had lagoons, according to an investigation of the Financial Times. What happened. The Financial Times has accessed sales contracts, to presentations of companies already involved in the industry and has drawn a conclusion: three months after Trump harden the export control, chips worth $ 1 billion were sent to China. In context, it is a huge figure, if one takes into account that Nvidia entered 17,000 million last year. The process began in May according to the Financial Times, when Chinese distributors began marketing GPU on which restrictions on data centers that work with Chinese Laboratories of AI weigh. The investigation points to something that the US already suspected: Many chips enter from Southeast Asia They are not any chips. The investigation reveals that Chinese AI companies are managing to acquire the GPU B200 of Nvidia, a beast that It already has a successorbut that is a candy to train models. And it promised multiply by four The performance of the desired H100 in MLPERF 4.1. The investigation also mentions the sale of other chips on which export controls weigh, such as the aforementioned GPU H100 and its successor, the H200. The price of a Rack Of eight B200 ready to use is approximately $ 489,000, and has dropped in price since they arrived in China in May. The difference with the sale that is authorized? An extra 50%. Publication in social networks announcing the sale of ASUS H200 racks. Image: Financial Times Nvidia’s position. The company has maintained a defense position to remain in China these months, and it is that this market supposed 13% of its global income. Jensen Huang has been praising the Chinese models of AI At a complicated moment for the company, in need of strengthening its complicity among Chinese companies while just selling chips. In full Dilemma for the US to sell or not sellHuang has placed the power of Huawei’s solutions at the height of the H200. A path full of difficulties. As Nvidia told Financial Times, buying chips clandestine is not something that allows expected yields. Mounting a data center with the GPUs is not just a process of installing parts, but about giving them service and support, something that the company does not supply to chips sold outside authorized channels. According to an operator of a data center, the export control does not prevent NVIDIA chips from reaching China, and what it does is create inefficiencies and “huge profits for intermediaries that assume risks.” Even so, a distributor recognized that “there is no shortage.” The effect of relaxation with H20. With the announcement of the permission to the marketing of the H20 to China, the sales of the B200 and other chips marketed in the black market have fallen, according to several distributors. The reasons are not clear, but buying Nvidia guarantees the aforementioned support as well as a more competitive price. Despite this, there are Chinese distributors announcing stock of the B300, which is not yet manufactured in mass.

It is one of the ugliest ferraris and cannot be driven either on street or circuit. And yet it is worth more than one million dollars

From the Ferrari factory in Maranello some of the most beautiful cars in history have come out. Jewelry like him Ferrari 250 Gto, Rome, Laferrari or the Ferrari Daytona SP3 are some examples of the good taste and exquisiteness that cars bend with the shield of “Il Cavallino Rampante“ However, there are others that, let’s say, that you have to get used to looking at them. This is the case of Ferrari F150 Muletto M4, a prototype that, directly, we can consider as the ugliest car of the brand. One so ugly, which does not even allow you to circulate on public roads or roll in circuits. Ferrari engineers went their hand Such and as they tell in Luxury launches The F150 did not come out of the pencils of no official designer of the brand (at least not one that had the design title), but is a mule: a prototype of tests in which engineers prove and develop the Future brands of the brand. The F150 Muletto M4 was born with a purely functional purpose that was based on the chassis of a Ferrari 458 Italia, adapted to test the New hybrid V12 engines that Ferrari developed at the beginning of the 2010 to boost the future Laferrari. Internal level, Laferrari’s project was known as F150, and hence, being the mule of its engine, this Begindro Prototype received the name of F150 Muletto, in its fourth development. Computer simulations help for much of the development, but when it comes to refining mechanics, it is necessary to touch asphalt. That forced Ferrari’s engineers to put that engine on wheels and take it out in these mules to shoot through the private circuit of Fioran, away from the curious looks. This is how this car, although in appearance, was the protagonist of hundreds of kilometers of trials in secret. The Ferrari engineers approach to this prototype was absolutely practical and, as it is obvious, Aesthetics It was in the background. Rivets throughout the body, a nose that fights against the laws of physics (and good taste) exhaust pipes that stand out from the body and removable panels covering the engine so that engineers could more comfortably access the new propeller to apply changes are the explanation of its disastrous design. Ferrari finished the first phase of Laferrari motor tests between May 2011 and December 2012, so, with the main completed developments, the prototype ceased to be useful. Ferrari thought that instead of discarding it Without further ado it would be a good idea to offer it as rarity to the most faithful fans of the brand. He did it with a single condition: they could never be homologated, so this car could never step on the street Not a public circuit. It is, therefore, a whim for engineering and history enthusiasts. A AUCTION FOR INSOLITO PRICE The F150 Muletto M4 still maintains the original version of that V12 hybrid engine capable of delivering 789 hp, compared to the 963 hp of the final version that ended up promoting the Laferrari de Production. This peculiarity is precisely what gives its historical and experimental value to the prototype, being a key piece in the development of the Ferrari hybrid range. Now, the RM Sotheby’s auction portal will present it On a bid on August 15, testing the fervor of Ferrari collectors for the unique pieces, regardless of their real functionality or appearance … controversial. At least on this occasion, we can say that real beauty is inside. In Xataka | Ferrari had been demanding a toy company for 10 years.

Chinese mobiles have batteries 11% higher than those in the rest of the world. The culprit is called sic

Chinese smartphones have a clear advantage: their batteries are 11% larger than those in the rest of the world. A consolidated suspicion that is now measured thanks to Counterpoint Research. The average in China reached 5,418 mAh in May 2025, compared to 4,900 mAh in the rest of the world. The difference has expanded to exceed 500 mAh in recent months. Why is it important. China is adopting carbon-silicio batteries (sic), a technology that allows greater energy density without increasing the thickness of the device. The rest of the world maintains more conservative technologies even though Two years ago we warn of this impact. The context. Chinese brands have opted to solve one of user’s biggest headaches: autonomy. With larger screens, more frequently soda and applications that consume more energy, including Local generative AIThey need more capacity. 6,000 mAh or more mobiles already represent 35% of the Chinese market, compared to 9% of a year ago. OnePlus leads with the greatest average capacity thanks to Your Ace series, exclusive to China. There is a revealing pattern: brands such as Honor, Huawei and Vivo launch models with larger batteries specifically for the Chinese domestic market. But their global versions maintain minor capacities. Why does this happen? Because China is its test laboratory: SIC batteries certifications are more agile there. In China you can try that technology before facing the expensive and slow western approval processes. It is cheaper to try at home than to risk out with a new technology. And now what. China will maintain this short -term advantage while Western brands wait for SIC technology to mature. The gap will be reduced when more manufacturers adopt large batteries as a global differentiation factor, and not only in China.

A small town in Holland has the solution to mass tourism: to fool Google Maps

Mass tourism has unable consequences for residents. Recently we talked about the Avalanche of tourists who go to the lavender fields in Brihuega. In the Parkbuurt neighborhood, located in a small coastal town in Holland, they also have problems with tourism. Specifically because, in the most influx days, it is impossible for them to park. The neighbors have got to work to solve it with a very ingenious method. Fed up neighbors. Parking in Parkbuurt was not a problem until tourists arrived. Especially on weekends, its streets are filled with cars and neighbors, fed up with not being able to park normally, as they say in NH News. What they did was start reporting street blockages on Google Maps so that the app sending visitors to other areas. Google Maps to Rescue. It is the navigation app most used in the world And its function to report incidents on the road makes it perfect for this type of actions. A single report would not take effect, but with neighbors organizing to send reports at the same time the thing changes. The streets of the neighborhood appear as cut in the app and that makes visitors go to other areas. Answer. The trick has worked for them, but it has had some unwanted effects. Gert-Jan Bluijs, councilor of the municipality, is not funny and ensures that this measure has generated more chaos in other adjacent neighborhoods. The neighbors defend themselves from criticism ensuring that it is a peaceful measure that only apply on weekends, during the week they were not applying it. They see it as a way of exerting pressure to do something from the City Council. At the moment, what the City Council has done is to place a sign at the entrance of the town asking visitors to deactivate Google Maps. More cases. It is not the first time that similar tactics are used to combat tourist saturation. A few months ago something similar also happened in Holland, near the area of the Keukenhof Tulipanes gardens. This same year, we knew that Barcelona had eliminated a Google Maps bus route so that tourists would not collapse it. The result was good in that bus line, but others collapsed. The other face. We have seen that navigation apps can be a tool to divert traffic, but they can also be the cause of the problem. Years ago we told you how Waze’s suggestions ruined the tranquility of some neighborhoods. The app, now GOOGLE PROPERTYsuggests faster routes and diverts traffic through streets that used to be little busy.

The “Death whistles” Aztecs were always a mystery. Until we discovered why they give us so many chills

The “Death whistles” Aztecs have surprising peculiarity: their intimidated appearance, but much more does its sound. Although the artisans manufactured them in the shape of a skull and figures that are today interpreted as references to Mictlantecuhtlithe Aztec King of the underworld, it is his loudness that has been intrigued by archaeologists for years. Not surprisingly if one takes into account that when we take one of these instruments to the lips and blow, something occurs similar to a human cry. It’s hard to listen to it without feeling uncomfortable. A group of researchers wanted to go further and investigate why we feel what we feel when we listen to the whistles of Aztec death. The answer can be key to understanding a piece that is still involved in mystery. Death whistles? Exact. His name imposes, but not as much as his appearance and sound. The “Death whistles” Aztecs are instruments made with clay between three and five centimeters and skull form, a peculiarity that experts interpret as a reference to Mictlantecuhtli, the lord of the underworld. They also include Figures of the Snake of Fire and Owls. Experts believe that the original pieces were manufactured Between 1250 and 1521. Wars or rituals? The first references about them date from End of the 19th centuryalthough probably the most famous specimen was found between 1987 and 1989 in the Ehécatl-Quetzacóatl templein Mexico City. There the archaeologists located the skeleton of a human sacrifice with a whistle, which has given wings to the different theories that try to explain what they were used for. There are those who think that the Aztecs used them in wars to scare their enemies and who believe that their use was basically ritual and symbolic. According to them, the sound would accompany the dead on their trip to Mictlánthe Aztec underworld. To that last theory contributes that death whistles have been found in places where ritual burials and human sacrifices were made. Another interesting clue is that the piece located next to the skeleton recovered in Ehecatl-Quetzcalcóatla circular sanctuary dedicated to the god of the wind, Ehecatl. Today several copies are preserved in facilities of the National Institute of Anthropology and History (INAH) or the Berlin Ethnological Museum. And how do they sound? Here are A few examples So you can check it. Depending on how they are used, whistles produce a siseo or a much deeper, intimidating sound, similar to a human cry. Recently a group of researchers from the University of Zurich (UZH) set out to go nevertheless and answer two big questions: why do they sound like they sound? And why listening to them produces such an overwhelming feeling? Their conclusions were reflected in An article Posted in November in Communications Psychologya magazine of the prestigious Nature Group. How have they done it? With a combination of techniques. The team obtained recordings from several whistles, including two recovered in Tlatelolcohe performed computerized tomographs To create 3D objects and resorted to replicas of whistles made of artisans with clay simulating the characteristics of the originals. Then they registered the sounds and reproduced them to a group of volunteers. To document their reactions well, scientists submitted them to a neuroimaging study. The objective: find out how their brains reacted. What did they find out? To start they discovered that the whistles have “A unique internal construction”with two opposite cameras that generate turbulence in the air and produce that kind of shout that, if archaeologists are right, accompanied the ritual victims in their descent to the underworld. “The whistles have a very unique construction, and we do not know any comparable instrument of other pre -Columbian cultures or other historical and contemporary contexts,” Explain Sacha Frühholz, the professor of cognitive and affective neuroscience who directed the study. The Aztecs are also known for making instruments that imitated the sound of the wind or the songs of the birds. What did they feel when listening to it? That is the most interesting part of the research. The volunteers described the sounds as “extremely chilling and terrifying”, According to verifies The UZH. “The brain regions belonging to the affective neuronal system responded strongly to the sound, which once again confirms its intimidating nature. The team also observed brain activity in regions that associate the sounds with symbolic meaning.” In summary, the volunteers called him “very negative” and “frightening.” “Given the aversive/terrifying and associative/symbolic sound nature, as well as the locations of the excavations known in places of ritual burial with human sacrifices, its use in ritual contexts seems very likely, especially in rites and sacrificial ceremonies related to the dead,” They conclude The experts, who recognize in any case a handicap of their experiment: the test was done with listeners of modern Europe who did not know that they were going to listen to the sounds produced by the old Aztec instrument. Did they find out anything else? Yes, something interesting. The volunteers perceived the sounds of whistle as hybrids, between the natural and the artificial. “They were classified at the psychoacoustic level as a hybrid mixture of voice sounds and screams, but also caused by technical mechanisms,” says research, which slides that this double quality could influence the reaction of the listeners: sound evoked shouts of a human nature, but also tones generated with artificial objects.

Catalonia and Murcia were two of the areas most affected by the drought. Now they are in the center of the storm

Of the 10 meteorological stations that Yesterday they collected more rainfall Five were in the province of Barcelona. At 11:00 today, the five stations that have collected more rainfall today are in the province of Murcia. A trough in summer. During the last days a trough has traveled the north of the country and the Mediterranean basin, but it has been this last area that has taken the worst part. This event has left large hail images and some overwhelmed channels in the center and north of the Mediterranean slope. The good news is that these areas where the rains now accumulate are some of the most punished by the drought that until a few months ago ravaged the peninsula. A drought whose effects still last in some of these areas. The most affected by drought. The Catalan and Safe internal basins were among the basins most affected by drought. In March last year, the Catalan basins stayed Below 15% of its capacity. After a slight rebound, at the beginning of this year their levels were Something above 30% of its capacity. Since then the Catalan basins have recovered and their reservoirs They are now to 77.6% of its capacity. Something that has not happened in the case of reservoirs in the Segura Basin. These reservoirs came to 19.2% of its capacity And, although they have recovered, they still remain in a modest 28.7%. The passage of a trough. The arrival of the last trough I could help To relieve the situation in areas such as the Safe Basin and to consolidate the stabilization of the basins of the north of the Mediterranean aspect, not only in Catalonia, also in the Júcar. For now the figures left by the trough are only provisional, although in the last Weekly balance of rainfall Made by the State Meteorology Agency (AEMET) stand out accumulations greater than 60 mm in Catalonia during the day after day, day 23. The data of the weather stations of the area indicate that yesterday’s was another rainy day. Change of trend? Meteorologists expect the situation to calm down today, but the longest tendency is not so clear. A few days ago it seemed that we were in a brief Impla before the return of heat.
