Science suggests that we are ignoring ultradian rhythms

by

We have been hearing about the circadian rhythmsand we know well that the blue light from screens before sleeping is bad or that the melatonin sends at night to induce sleep. However, there is a second biological clock that is much less talked about, but which dictates exactly why at 11:30 in the morning we feel invincible, but when 1:00 p.m. arrives we cannot keep our eyes open to work. These are the ultradian rhythms. Its foundation. Far from being an invention of productivity gurus, the existence of these rhythms is deeply rooted in our physiology and hormonal secretionespecially during sleep. But the important thing is that understanding them will not give us superpowers, but according to scientific and neurobiological literature, it does explain how the brain “battery” works. What are they? To understand ultradian rhythms, we must travel to the 1950s and focus on Nathaniel Kleitman, the pioneering researcher who discovered REM sleep. At this point, Kleitman and his team realized that we don’t sleep in one uniform stretch, but rather our night is divided into cycles that last between 90 and 120 minutes. During each cycle, we go through several stages, such as light sleep, deep sleep and also REM sleep. Once we reach this we start again, and this is what is known as the ultradian rhythm. It is maintained. Logic could make us think that this cycle remains only in sleep, but here Kleitman postulated the Basic Rest-Activity Cycle (BRAC). With this theory on the table, it was proposed that this same 90-minute clock does not turn off when we wake up, but rather that during the day our brain continues to operate in waves. In this way, we can see that we have peaks of high alertness and concentration of about 90 minutes, followed by valleys of fatigue of about 20 minutes where the body requires a rest to recover. A hormonal issue. Something that is well known is that the secretion of hormones is not done continuously like an open tap, but in pulses or “peaks” that are synchronized with these 90-minute cycles. For example, growth hormone is essential to repair our tissues and its maximum peak is linked to the stages of deep sleep that occur in the first ultradian cycles of the night. This means that, if these first 90-180 minutes of sleep are disturbed, the body will not repair itself in the same way. Respect the ultradian rhythm. Among the tips we can follow to control these cycles is the 90/20 rule at work. And if we assume Kleitman’s BRAC cycle, the optimal window of mindfulness lasts about 90 minutes and then we enter a moment of fatigue where we do not perform in the same way. That is why it may be best to work for 90 minutes and then take a real break away from the work screen, for 15-20 minutes to reset this cycle. But the moment of waking up is also essential, since feeling tired when getting out of bed usually occurs because the alarm went off in the middle of the slow wave sleep phase or deep sleep. That is why calculating the hours of sleep in blocks of 90 minutes increases the probability that we will wake up at the end of these cycles and be able to get up with much more energy.

The Wangiri scam only needs one thing to work: your curiosity

by

Someone calls you on your cell phone suddenly and hangs up right away, before you can react. You look at the screen and see an unknown number, so immediately you wonder who was calling you and why. The impulse is often to call back. And that’s probably a really bad idea. The Caller’s Trap. This scam became famous a couple of years agobut now it seems to be coming back strongly and it is good to remember how it works. This is a scam known as ‘Wangiri’ (ワン切り), a Japanese term that literally means “one ring and hang up.” The mechanics of fraud are as old as it is effective: An automated system launches thousands of random calls a day, lets the phone ring once or twice, and immediately hangs up before the user has time to respond. The bait of the missed call. The goal of scammers is to play on your curiosity or fear that you have missed some important communication. When you see the notification on the screen, many people can act impulsively and they call back to find out who was trying to contact them, which leads them directly into the fraud. If you call back, it will be expensive. The real danger is in calling back: without knowing it, what happens is that you will be calling a special rate number abroad that is not included in any mobile operator rates. Cybercriminals often camouflage numbers with strange international prefixes from countries like Albania (+355), Bosnia, (+387), or Ivory Coast (+225) that are very difficult to recognize. waiting music. And when the call is initiated, scammers activate systems to keep the victim on the phone as long as possible. For this they use fake voice recordingssimulate that the call is on hold or play sounds of a busy line. Every second you listen to those loops, the cost of the call goes up significantly and without you knowing it. A volume business. Although the amount charged to each victim may be small, the scam ends up being a million-dollar business when carried out on an industrial scale. Cybercriminals use bots and automated systems that make millions of attempts daily at dawn or at unusual times to maximize the probability that the user will not reach the cell phone in time. It’s easy to avoid the scam. The scam is simple and effective for impulsive users, but there is a very simple way to avoid it: never return a missed call from an unknown number. And much less if it has an international prefix other than +34 of Spain. If there is really an emergency, that person will contact you again or will leave a message via SMS or WhatsApp. If you have already fallen into the trap. For those who have been victims of the scam, the ideal is to act quickly. The first thing is to check the accumulated consumption in the application of your mobile line and immediately contact your telephone operator. Save the scammer’s number, write down the exact time of the call and ask your company to preventively block charges for premium rate numbers before processing the report.

One of the most famous western phrases is in a Clint Eastwood film, but it was improvised by one of his companions

by

An actor who, a priori, did not have to say any dialogue, fired four shots and uttered a phrase that sixty years later is still quoted in all Western stories. But that phrase wasn’t in any script. What’s more, the actor who pronounced it was not even the protagonist of a legendary spaghetti western work: ‘The Good, the Bad and the Ugly’. What’s happening. Tuco (Eli Wallach) is taking a bath when an old enemy surprises him with a revolver. Tuco shoots through the bathwater, cloudy with dust and soap, gets up and blurts out: “When you have to shoot, you shoot, you don’t talk.” According to Wallach himself, the scene I had no dialogue; It was he himself who improvised the phrase on the spot, and both Sergio Leone and the rest of the team laughed so hard that they kept it in the final cut. It is significant that the phrase was only uttered on two occasions: one during filming, in 1966, and another a year later, when dubbing the scene in the studio. How it got there. The actor used to say that Leone had signed him for his role as the bandit Calvera in ‘The Magnificent Seven’. However, what actually convinced Leone was a specific moment from ‘The Won of the West’, from 1962. Wallach recalled that his agent told him about “an Italian director who has seen your Western films”, to which he responded skeptically that he did not believe that Italian Western existed. However, he changed his mind when Leone showed him a sequence from ‘Death Had a Price’. All yours. Once he won the role, Leone let him do practically whatever he wanted with Tuco: the straw hat, the leather knee pads, the gesture of crossing himself at full speed several times in a row, it was all Wallach’s idea. Also he improvised almost the entire armory scenedespite having no idea how to assemble a revolver, and the real bewilderment of the clerk who was explaining the parts to him was captured on camera. Eastwood’s jealousy. The star of what would be the third film in the Dollar Trilogy worked in a much more contained manner, and his final presence on screen was much more dependent on editing. The script distributed the narrative weight between three characters for the first time, and he was not happy about that. In fact, Clint Eastwood he was close to turning down the roleuncomfortable with Tuco having more footage and better lines than him. He negotiated $250,000 and 10% of the profits in the United States before accepting. The film would end up grossing more than 38 million dollars with a budget of just 1.2 million, a success that consolidated both Eastwood’s status as an international star and Leone as a leading author of the genre. However, his fears were more than justified: decades later, it is Wallach’s improvisations that are most frequently cited when discussing the film. That’s what the classics are: untamable.

an alien-looking observatory in the middle of the desert

by

Life is what happens while Saudi Arabia builds mega constructions. Or plans them, rathersince in that particular competition against the United Arab Emiratesright now there is more on the plane of ideas than on the sand of the desert. With the disaster of The Line still kickingthe country has another mega construction in mind: an observatory called AlUla Manara that seeks to become a unique tourist destination while serving as a beastly tool for astronomers. Its location is privileged, but what stands out most at first is, obviously, that design that seems more like an AI hallucination than a real building. AlUla Manara. When we talk about mega constructions in Saudi Arabia, we immediately think of Neom. The pharaonic project was not only going to house The Line, but another series of ambitious facilities, but there are other areas and projects in which the country has been injecting money for years. AlUla is a region of contrasts in which they mix World Heritage wonders with buildings that they seem from another planet. In that bag we have to put AlUla Manaraan astronomical complex that will become one of the largest optical observatories in the world. This is a project of the Royal Commission for AlUla to reinforce the role of Saudi Arabia in the international scientific community, but also seeking to position it as a new tourist pillar in the area. Peculiar design (with meaning). The images (conceptual, of course) reveal a building that is totally contrary to what we usually identify as an observatory. Instead of a huge dome that rotates and allows the telescope to be oriented, the observatory will have several more or less fixed telescopes. The main will count with four meters in diameter and will be accompanied by two others of two meters in diameter. It will not only have optical observation systems, but advanced systems such as LaserSETI that will allow monitoring the sky for flares, several observation platforms, tracking technologies and equipment for astrophotography. Integration. But, as we say, beyond the equipment, what stands out is a design signed by Heatherwick Studio, responsible for projects such as Little Island in New York or Azabudai Hills in Tokyo. The inspiration for the observatory is the spiral shapes of galaxies, as well as patterns present in fossils, although you have to use your imagination. Like the Maraya Concert Hall auditorium, full of mirrors in the middle of the desert to blend in with it, the observatory will seek not to break with the aesthetics of the region. This “flower”-shaped structure will be covered with local stone to integrate into that environment. Privileged. The AlUla Manara will be built on a plateau about 70 kilometers north of the city of AlUla and, like themselves they boastthe location is spectacular. This plateau is located in an area that is within what is known as a ‘Dark Sky Park’, a certification that makes it clear that the skies are exceptionally dark because light pollution is minimal. In fact, it is one of the best places on the planet to observe both the Milky Way and a few million other stars, which is why it will seek to exploit both the observatory’s capacity in scientific matters and monetization thanks to tourism. The visitor area will count with exhibitions, workshops and experiences designed to harness the potential of the facility and the area. But, in addition to the areas focused on tourism, there will be spaces where visitors can see scientists during their work day. Stuart Wood is the director of Heatherwick Studio and pointed out who saw an opportunity to dissolve the barriers that usually exist in this type of facilities. Let’s see what happens. All this sounds very nice and with the failure of The Line it is already difficult to believe certain things that come from Saudi Arabia, but AlUla Manara is a much more limited project that will be located in a region that already has real tourist interest and where it has been shown that this type of buildings have an outlet. Furthermore, it is a conjunction between science and tourism that is interesting and that, precisely, can make the project more viable. Now, there is still time to see that flower of the AlUla desert. The project was launched in 2023, but it was now that it was approved the final design of the complex, the scientific configuration and everything that Heatherwick Studio has in mind. It doesn’t look bad, but yes, there are still no dates on the table. In Xataka | China has no rival in megaconstructions: it even has the tallest abandoned skyscraper in the world

‘Backrooms’ is going to return to theaters with a 15-minute longer version. If successful, we will have a dangerous precedent

by

‘Backrooms‘ has raised a surprising 330 million in theaters with its first version in theaters. Wait: first? Are there different versions of ‘Backrooms’? Now it is: five weeks after the premiere, its production company A24 is bringing it to theaters again, this time with 15 minutes of exclusive material. Obviously it is not the first time that the industry has made moves of this type, but it is the first in which there is so little time between versions. And it sets a precedent that could give us more than one disappointment in the future if it is successful. The return A24 to relaunch ‘Backrooms’ on July 3 under the title Backrooms: Everything Must Go Edition, just five weeks after its original premiere on May 29. They are 15 minutes of “unreleased content in theaters”, and with special features: they will be included in block after the final credits, they have been directed by the film’s director Kane Parsons and it will be exclusive to this re-release and will not be seen in home editions or streaming. Less and less. The director’s cut or director’s cuts (something that this ‘Everything Must Go Edition’ is not exactly, since the new footage will not modify the existing one, but is extra material after the credits, like a “deleted scenes” extra on a DVD) are not new in the industry. They have existed since 1942, when Chaplin’s ‘The Gold Rush’, from 1925, was re-released with new material. The modern concept was born in the seventies with Peckimpah’s ‘The Wild Bunch’, when a restored version was released in cinemas. The most popular was the Director’s Cut of ‘Blade Runner’, ten years after the release of the original, with changes that modified the meaning of the first film. In all of them and others equally popular (and often released in cinemas), such as ‘Close Encounters of the Third Kind’ or ‘The Gates of Heaven’, there is a coincidental pattern, and that is that the rerun comes years after the original premiere. And often, accompanied by a discussion about the emasculating power of the industry, which prevents the full expression of the creator’s version. He director’s cut It is an advertising tool, yes, but it is also a vindication of the films without interference from the studios. This time, the studio itself releases an extended version when no one has complained that the first cut is mutilated. The danger. It’s clear what’s at stake here. If the move is successful, the next step is to release intentionally “incomplete” versions to generate two box office cycles. First the base audience is reached, and then, weeks later and when the hypethe film is re-released with “exclusive” material. Here specifically, the move is clear: that the production remains profitable in the juicy weekend of July 4, very important at the US box office. The difference with very popular extended versions such as those of Peter Jackson’s ‘The Lord of the Rings’ seen on DVD, is obvious. A24, in question. Although for a time A24 has been the pretty girl of the Holywood production companies for his ease in taking risks, for cultivating undervalued genres and for supporting directors with clear auteur visions (and still get blockbusters and sweep the Oscars), for a few months now his image has been questioned. To the open adoption of one totally pro-AI policy Now this very tricky marketing move is added. In a couple of years we will see if what today sounds like an extravagant maneuver becomes a standard tactic: launch “version 1.0”, wait for it to hit the box office, re-release a “complete vision” after a month and a half. Before the director’s cut It took months to arrive, now even those small islands of creative integrity have been subject to the extremely accelerated calendar set by social networks and the streaming.

It was a drone flying at almost 350 km/h

by

Latest Austrian GP in Formula 1 he left us quite surprising images. Not because of the events themselves, that too, but because of the moments that one of the cameras left us that plummeted over the Red Bull Ring, attached to the cars. The camera belonged to a fpv drone (first-person view) flying at the height of the cars, and ended up being one of the protagonists of the broadcast. Chasing cars. Last Sunday, during the Austrian Grand Prix, F1 used images from an FPV drone as the main camera for his coverage, something he had never done in this way. The stellar moment came on lap 11, when the drone flew at low altitude over the duel between Lewis Hamilton (Ferrari) and Max Verstappen (Red Bull), capturing the ups and downs of the Spielberg track at the same pace as the cars. The images were broadcast live and then repeated in the replay, placing the camera very low over the cars as they overcame the hills of the circuit, according to collect the specialized media DroneXL. Click on the image to go to the post Leadership. Until now, these types of plans were used as an occasional detail within the production. This time, the organization itself decided to give it prominence. In fact, the official F1 account public a quick and low step over the circuit, and the Red Bull team itself shared the overtaking between Hamilton and Verstappen, inviting fans to stay for the drone images. Where does this technology come from? F1 has been trying to incorporate this type of shots for years. Just like share In the middle, the first attempt dates back to the 2022 Spanish Grand Prix, although the result was quite average, since the drone used a basic camera and the image quality was not up to par with the rest of the broadcast. A year later, in Las Vegas, drone pilot Johnny FPV managed to chase a Red Bull car through the desert all the way to the Strip with a much more decent result. But the real technical leap came with the independent project of the Dutch Drone Gods, in collaboration with Red Bull Advanced Technologies. According to point DroneXL built a custom chase drone and completed a full lap behind Verstappen’s RB20 at Silverstone, reaching 310 km/h on a straight line. The 350 km/h drone. This project is called Red Bull Drone 1 (RBD1) and is, to date, the reference in speed within this terrain. It weighs less than a kilogram, is made of carbon fiber, fiberglass and 3D printed polymers, and is capable of going from 0 to 100 km/h in less than two seconds and from 100 to 300 km/h in another two, with a maximum speed of 350 km/h and forces of up to 6G at full load. According to explained its pilot, Ralph Hogenbirk, known as Shaggy FPV, told Motorsport, the order came directly from Red Bull, which wanted a drone capable of following a Formula 1 car during a complete lap, maintaining its pace and recording it with an eye-catching result. The pilot himself acknowledges that this is already the third version of the device, having completed months of testing. As a curiosity, the RBD1 does not have brakes, so to reduce speed when cornering it simply stops accelerating and brakes in the air, forcing the driver to anticipate where the cars will brake. Click on the image to go to the post It is not confirmed that it was the same drone. At the moment, it is not confirmed that it was exactly the same device that we saw in the broadcast. According to point DroneXL, the RBD1, remains a private project that F1 is trying to incorporate into its races, but negotiations are being complicated because at the moment this model cannot fly over the public or cross the track. The most likely thing, according to the media, is that the images from Austria came from F1’s own drone system that F1 already uses in other events on the calendar. The organization operates its own internal drone system for around ten races per season, in circuits such as Bahrain, Miami or Budapest, choosing this equipment because it is already approved and is easier to approve compared to the licensing, insurance and safety regulations that change from one country to another, according to explained to SVG Europe the head of F1 TV production, Dean Locke. It’s not easy to take one of these drones to a race. Flying an FPV next to an F1 car is not the same as doing it in a rally or on an empty circuit. Dean Locke has explained on several occasions why the Red Bull drone, despite its performance, still does not have free rein to race alongside the cars in an official session. And it cannot fly over the fans, it cannot cross the track and, lacking a moving head, it must limit itself to following the car from behind or from the side. Added to this is that the air trail generated by F1 cars at these speeds can divert the trajectory of such a light device, something that Hogenbirk himself had to overcome during filming in Silverstone. And now what. F1 itself has acknowledged that it continues to explore this avenue, although progressively. Locke has pointed that there are sections of some circuits, such as the back straights of China or Austin, where there could be room to use technology similar to that of the RBD1 without putting the public at risk. For our part, as fans, I hope so, because the images left by these devices are spectacular. Cover image | F1 and Red Bull In Xataka | The great challenge of electric cars is how to charge them.

It had been collecting dust in a drawer for decades

by

Modern paleontology right now has two large fields of work, one of them being expeditions in remote places and the other being museum shelves. And it is no wonder, since the greatest discoveries are not made by breaking stones under the sun, but by cleaning dust from drawers that have been closed for decades. This is exactly what just happened to an antarctic fossil which, after years stored in the United Kingdom, has revealed to be a key piece in understanding our planet’s past. A new test. We are not facing the “first dinosaur fossil in Antarctica”, but rather we are facing the first fossil of this type that has been identified after a long wait in a ‘drawer’ of a museum archives. The files. The history of this bone is, in itself, fascinating, since, as has documented the BBC, the fossil has been in the British Antarctic Survey collection. For decades, it remained in a taxonomic limbo and although its existence and its Antarctic origin were known, the anatomical scrutiny necessary to classify it accurately had not been carried out. Now, a new study has put an end to the mystery, as researchers have reexamined the morphology of the bone and concluded that it belongs to a titanosaur sauropod dinosaur from the Late Cretaceous. Your base. To reach this conclusion we did not start from scratch, but there were already previous records about the presence of sauropods in Antarctica. What is interesting about this new study is that it connects the dots, providing the formal and rigorous identification that this piece of the archive needed to enter the history books. A green Antarctica. Identifying a titanosaur in Antarctica raises a mental image that clashes head-on with the current landscape of the continent. Right now we know that titanosaurs were a group of sauropods that included the largest land animals to ever walk the Earth. But the question we ask ourselves is clear: What was an animal of these proportions doing in an ice desert? The answer is that the Antarctica of the Late Cretaceous period was nothing like today’s Antarctica. Specifically, about 70 million years ago, the continents were arranged differently, since South America, Antarctica and Australia formed intermittent land connections. This means that Antarctica was not covered by kilometers of perennial ice, but instead was home to vast forests of conifers and ferns, an ecosystem rich and temperate enough to support the migration and diet of these gigantic herbivores. Its importance. From a scientific and informative point of view, the value of this news does not lie in a recent heroic expedition under snow storms, but in the relevance of institutional collections. The BAS fossil catalog shows that we still have fragments of Earth’s history gathering dust, waiting for current scanning technology or expert review to give them their true meaning. This fossil, now officially recognized in primary scientific literature, is not “the first Antarctic dinosaur,” but it is definitive confirmation that, in Earth’s remote past, there was no barrier or latitude that could resist the footsteps of a titanosaur. In Xataka | We thought that human beings began to walk in Africa. This 7.2 million-year-old fossil says otherwise

Honor Watch 6, analysis – Review with features, price and specifications

by

I think I have hit the ceiling when it comes to the battery of a smartwatch: I have not tested any with greater autonomy than the Honor Watch 6. This is already a merit, but it is not the only thing: I had not tried a watch from the brand for a while and it has just become one of my future favorites to wear on my wrist. I liked it a lot. And, despite what I missed, I won’t have a hard time recommending it. After 14 days testing the new Honor watch, this has been my experience The last thing you want is to worry about the battery. You are looking for a quality sports watch at a price that is not exaggerated. You want continuous health monitoring without draining your battery. You are looking for an operating system to install applications on. You want to pay with the watch: I couldn’t use payments. You need a smartwatch with eSIM. The essentials in 30 seconds It is a large watch, somewhat heavy and with a 100% sporty appearance. You have it in stainless steel (brown) and aluminum (black). In both the hardware is identical, as well as the touch and finishes: it exudes premium essence. Although that is not what stands out the most: The Honor Watch 6 lasts more than four weeks on a charge. With a sports record at a very good level, sensors that measure general health and that send the data to an easy-to-read application. I found it to be a smartwatch that is a couple of steps away from becoming a blind choice: it lacks mobile payments (Honor includes support for Fidesmat the moment it does not work) and be able to install applications. You stay with what comes from the factory. It is more than enough if you are an amateur athlete, but it cannot replace the telephone. It receives and makes calls, yes, but it cannot respond to messages, even with text templates. It also cannot work in standalone mode. It is very precise in the exercise, covers some sports in an expanded way (such as soccer) and even includes a voice coach (only in English). The Honor Watch 6 is a watch that you don’t worry about, in exchange for suffering shortcomings if you come from a complete operating system, such as Wear OS or WatchOS. 9.0 Design 9.5 Screen 9.0 Software 8.2 Battery 9.7 Interface 8.5 in favor Battery that never runs out.

You can call from your wrist, not reply to messages. It also does not allow you to install third-party applications or spheres. Of course, it comes with the best collection of “watchfaces” that I have seen on a watch of its type. All free, good here. It looks wonderful. The screen is large, as is the watch. I have had no problems seeing it even while playing sports under the June sun. The interface makes it easy to interact with all the apps and services, it has a flashlight and a collection of very well finished widgets. Quality is appreciated in all aspects of the watch: from the exterior design to the interface navigation. If you have used a smartwatch you will not miss out on the Honor Watch 6. Did someone say variety of sports? Up to 120 practical time clock. The GPS measures routes outside (it is fast and sufficiently accurate), the races have a somewhat heavy trainer that can be deactivated (too bad it only has English), there are unusual exercises (there is paddle tennis, but not the mountain bike) and Honor specializes in practices such as soccer. The clock knows how to return in case you get lost in the mountains. It’s not a medical watch, but it comes close. With its quotes, since it is not certified as a health device. Even so, it measures the usual variables and is capable of doing a body analysis to know the general physical condition. Heart rate measurement is acceptable, although it presents some difficulty in recording rhythm changes at high heart rates. It measures the lactate threshold and can even provide an age estimate based on the recorded exercise. He told me that I am eight years younger, for that reason alone the review has already been worth it. The jewel in the crown: autonomy. It’s the closest I’ve ever come to charging my watch and forgetting about it until the next month. In fact, I haven’t even charged it twice during my analysis: once was enough (approximately an hour and a half of charging). It should last just over four weeks with average use, daily sports recording and even outdoor training with GPS (according to the records I obtained during my test). I haven’t spent even 1% per hour on the race. With screen on, trainer and all sensors running. The closest I’ve ever come to giving a watch a ten.

Spain is burning and its nuclear power plants notice it. This is your strategy to endure

by

Spain is sweating again. extreme temperatures At the end of June, alarm bells have gone off in a good part of the country, and the Spanish nuclear park, responsible for about 20% of electricity what we consume, is not alien to this phenomenon. However, it is worth clarifying something from the beginning: whether a plant reduces its power or stops during a heat wave has nothing to do with a security failure. The seven nuclear reactors in operation in Spain (Almaraz I and II, Ascó I and II, Cofrentes, Trillo and Vandellós II) have been dealing with demanding summers for several decades, and their cooling systems were designed precisely with scenarios like this in mind. The Nuclear Safety Council publishes in real time the operational status of each plant, so anyone can check how they are responding. The key is in the external cooling circuitresponsible for evacuating the heat dissipated by the electricity generation process into the environment. In pressurized water plants, such as Almaraz, Ascó and Vandellós II, this circuit is the third in the installation, independent of the primary (which surrounds the core) and the secondary (which moves the turbine). Cofrentes, the only Spanish plant with a boiling water reactor, has a different architecture, a direct cycle, but it also depends on that same external circuit to cool the condenser. And this is where each plant plays its own cards depending on its geographical location. Three ways to beat the heat Ascó I and II, Cofrentes and Trillo are fed by river water, but they do not return it directly to the riverbed after using it. First, it passes by the cooling towers, those structures more than 160 meters high that we have described so many times when explaining the internal workings of a nuclear power plantand that dissipate heat into the air by convection and evaporation before any pouring. This drastically reduces the amount of water they need to extract from the river, up to twenty or thirty times less than if they did not have that tower. The sea has a thermal stability much greater than that of a river Almaraz represents a particular case because it does not depend on the flow of a natural river. It uses the artificial Arrocampo reservoir, conceived as a closed system that acts as a large heat exchanger. This independence of the river regime allows it continue operating normally even when temperatures soar, something especially relevant in a plant that will be the first to shut down: Almaraz I will close in November 2027 according to the current government calendar. Vandellós II draws on another resource: the water of the Mediterranean. The sea has a thermal stability much greater than that of a river, so it absorbs heat without its temperature rising appreciably. And, what’s more, it varies much less during heat waves. It is the same thermodynamic logic that explains why so many power plants in the world, from those that are cooled with seawater to those that use closed circuits like the one in Almaraz, prioritize the thermal stability of the cold source over any other consideration. When safety forces you to stop What can happen, and in fact happens quite frequently during the strictest summers, is that a nuclear power plant reduces its power or stops temporarily. The reason is not to protect the reactor, but the aquatic ecosystem. And the regulations limit the temperature at which water can be returned to a river or the sea, and if these limits are close to being exceeded, the facility prefers to slow down rather than breach them. It is an environmental decision, not a safety emergency. Meanwhile, the clock of the Spanish nuclear blackout continues to tick in parallel to these episodes of extreme heat. The current calendar starts in 2027 with Almaraz I, followed by Almaraz II in 2028. In 2030 it will be the turn of Ascó I and Cofrentes; Ascó II will close in 2032; and The process will be closed in 2035 with Vandellós II and Trillo, the last two plants to go out. Until then, each summer will be another test of resistance for a park that continues to provide a fifth of the national electricity.
