The duel over the new glass air fryers is decided on size and power

by

Until recently, air fryers were dark, noisy drawers that were simply used to reheat chips frozen. Today, smart cooking requires versatility, speed and, above all, the ability to adapt. In this field, Ninja It has become a fetish brand for technological cooking enthusiasts. Ninja CRISPi Portable Air Fryer, 3.8 l, 4 in 1 The price could vary. We earn commission from these links XL Ninja CRISPi PRO Glass Air Fryer, 7 Functions – Blue (2 Containers) The price could vary. We earn commission from these links With the launch of its latest range, the firm has put on the table two heavyweights that share DNA but aim for different profiles: the Ninja Crispi Pro and the standard Ninja Crispi. At first glance, both promise to retire your traditional oven and reduce oil use by 75%. However, when we fully enter into your specificationswe see that the battle is decided in the technical details and what you are willing to pay. We put two of the best air fryers of the moment to discover which is the smart purchase. Technical data sheet for both Ninja air fryers feature Ninja Crispi (Standard) Ninja Crispi Pro power 1,700W 2,050W larger container capacity 3.8 liters 5.7 liters (XL size) small container capacity 1.4 liters 2.3 liters cooking modes 4 (Air Fry, Roast, Reheat, Dehydrate) 7 (Add: Bake, Grill and Ferment) temperature range Up to 185°C Up to 240°C price from 123 euros 249.99 euros Design and capacity: from individual format to family feast Both models share the same revolutionary idea that is changing kitchens: the CleanCrisp. Instead of the typical plastic and Teflon basket that gets scratched just by looking at it, Ninja opts for borosilicate glass containers in which you can prepare ingredients, cook them with the hot air head, serve them directly on the table (since they have a very aesthetic design) and put an airtight lid on them to store them in the refrigerator. However, size does matter here. The standard Crispi model includes a 3.8 liter main bowl and a 1.4 liter secondary bowl. It’s a very portable and compact formatideal for singles, couples or to take the airfryer even to a second home. On the other hand, the Crispi Pro makes the leap to family format. Its XL container reaches 5.7 liters of capacity, enough space to roast a whole chicken with vegetables for up to six people, and its small bowl goes up to 2.3 liters to make generous side dishes. Power and temperature: the Pro breaks the 185ºC barrier This is where the Pro version gains muscle and where the price difference is justified as well. The standard Ninja Crispi is somewhat limited in power (1,700 W) and has a thermal limit of 185ºC. This makes it a perfect ally for reheating leftovers and leaving them crispy (thanks to the function Recrisp) or make everyday dishes, but it may fall short or take longer if you are looking for extreme browning on thick meats. For its part, the Crispi Pro goes up to 2,050 W and set the thermostat to 240ºC. That extra heat allows the airflow to seal the food much faster. Additionally, the Pro expands the menu from four to seven functions, adding key modes for cooking lovers such as Bake (bake), Gratinate (Grill) and Ferment masses, something impossible to do in the base model. So…Which model to choose Seeing the differences between both models of Ninja Crispi air fryers, you may be wondering which one to choose. If you don’t know which one to choose, this is what we advise you: Buy the standard Ninja Crispi if: You are looking for an ultra-portable system, you cook small portions for one or two, and your main objective is to use it for side dishes, quick dinners or reheat food giving it a crunchy touch without using the microwave. Ninja CRISPi Portable Air Fryer, 3.8 l, 4 in 1 The price could vary. We earn commission from these links Buy the Ninja Crispi Pro if: You want to completely replace your home oven, you need the capacity to feed a family (5.7 liters) and you don’t want to give up baking recipes, powerful gratins at 240ºC or homemade dough thanks to its advanced functions.

why the great battle of mobile cameras is in size and not in megapixels

by

How difficult can it be? know if the camera of one mobile phone is better than that of another. An example as a riddle, let’s see if you can see, at a glance, which camera is better. They are the two main cameras of two different phones: 50 megapixel sensor with f/1.7 aperture and one-inch size. 3.2 µm pixels and OIS stabilization. 200 megapixel sensor with f/1.7 aperture and 1/1.4 inch size. 0.56 µm pixels and OIS stabilization. Since a large number always attracts attention, a first glance could tell us that the camera with 200 megapixels is better than the one with 50 megapixels. Is that so? Well, not in this case, since the top camera (which corresponds to a Xiaomi 17 Ultra) It’s much better than the one below (from a Redmi Note 15 Pro+). That is something we could know from the size of the sensor and the pixels, which is exactly what we are going to explain in this article. A camera with more megapixels is not necessarily better Cameras are increasingly a claim by manufacturers when it comes to selling mobile phones. This is nothing new, since we have been seeing different races between them for years: first they were to offer more megapixels and then, to have a greater number of cameras. As we have seen in the example above, even cheap phones already have sensors with 200 megapixels. But, Does that mean the camera is better? In order to answer this question, we are going to explain what a megapixel is. A megapixel (also called ‘MP’ or ‘mpx’ on mobile devices) is equivalent to one million pixels and is an element that is not used to measure the quality of a sensor or an image, but its resolution. In short, the higher the number of megapixels, the larger the image size will be. This is very useful because it allows you to take large photographs and later make a digital crop to have an enlarged image. It is a very interesting solution for mobile phones that do not have a telephoto sensor (like the iPhone 17efor example), but it is not a factor that will determine the quality of the photograph. I understand this, now let’s talk about a key concept in photography: light. The more light a camera captures, the better the image quality and the less noise it will have. This is where pixel size comes in: the larger they are, the more light they are able to collect. What’s happening? That you cannot fit a huge number of megapixels into a small sensor because, in that case, each pixel receives less light. That is exactly the opposite of what we are looking for in photography, but it is a problem that is diluted if the sensor is larger. Why is sensor size so important? If the camera sensor is larger, the pixel and megapixel size will be larger. so they will capture more light. In fact, this is another detail that we can see in the example cameras that we used at the beginning of the article, since they tell us the size of their pixels measured in micrometers (or µm). The larger these are, the more light they will capture. Precisely based on this, manufacturers use a technique called ‘Pixel Binning’. Explained very simply, it is a process by which pixels join adjacent ones, thus forming larger pixels (and therefore, capable of capturing more light). There the number of megapixels (and therefore the resolution) is reduced in exchange for gaining more light. At this point, the question may arise in our mind as to why manufacturers don’t introduce larger sensors in phones. The answer, if we ignore the cost of these, is that you not only have to mount them: they have to be placed on the mobile so that it can take advantage of them 100%. And that takes up a lot of space on a device that seeks to be (relatively) thin. And where is the size of a sensor most noticeable? Well when we go to take a photo and there is little light. These large sensors offer more natural results at night and when lighting is poor, all without the need for overly aggressive software processing. It also performs very well with the contrast between dark and brightly lit areas, in addition to achieving a natural blur effect without having to resort to Portrait mode (or what is usually called ‘bokeh). How can I find out the size of a camera sensor? Sensor size is expressed in inches, usually as a fraction: for example, 1/1.95″. The smaller that fraction (closer to 1), the larger the sensor. A 1/1.3″ sensor is larger than a 1/1.95″ sensor. Megapixels are easy to sell because they are a large number and easy to compare in a store. Sensor size is harder to communicate, harder to manufacture, and harder to make profitable in the mid-range. That’s why manufacturers highlight it when they have it and omit it when they don’t.. Now you know which column to look at. Two mobile phones with one-inch sensors In recent months we have been seeing mobile phones with very good photographic sections and the vast majority of them (if not all) have one-inch sensors. It is true that we have mobile phones with an outstanding photographic section that barely have a sensor like this, like the Vivo X300 Ultra (main camera sensor measures 1/1.12 inch), he Vivo X300 Pro (1/1.28 inch) or the OPPO X9 Ultra (also 1/1.12 inch). There are many aspects that come into play when talking about mobile photography. and not all of them are physical (the processor and software also have a lot to say). Now, we have two good examples with one-inch sensors that we are going to see right below. Xiaomi 17 Ultra We have used it as an example because the Xiaomi 17 Ultra is one of the best cameras we have seen on mobile phones … Read more

Three settings for iOS and Android that are more effective to avoid straining your eyes if you have presbyopia than changing the text size

by

If you are already a few years old and presbyopia is starting to make an appearance, don’t limit yourself to making the text on your cell phone bigger. Let’s tell you others three most effective adjustments to avoid straining your eyes that you can turn to, and that are available on both Android and iOS. These are three fairly simple adjustments that are not going to be as disruptive in terms of showing less content on the screen as when you increase the font size. However, they are going to be even more effective in helping you read. The key is contrast, bold and white balance. Expands screen contrast In the accessibility options of your mobile you have an option to increase contrast or high contrast text. By doing so, there were no more pale grays or blues that are difficult to read, the mobile will force the apps to show the maximum contrast in your texts to make them easier to read. You can combine this option with reducing transparency on iOS or disabling blur effects on Android, to eliminate some translucent effects that can make content difficult to read. Turn on bold text On iOS, within the text display and size section in the accessibility options you will have the option to activate bold text. With this you will make all the letters of the operating system, from the clock to the notifications, appear in bold. This will make all text easier to read without having to make it larger. In Android 16 you will have an even more advanced option, which is outlined text, within the Screen and text size section in the accessibility options. This will add a small border to each character to make it much easier to read, even when there are complex backgrounds behind it. Adjust the white balance The third setting that I recommend you try is the white balance. In iOS the option is called Reduce white pointand it’s in the display and text size settings in the accessibility section. On Android the equivalent is in the screen tone settings, within the section Screen. With this, what you will do is reduce the intensity of pure whitesnot the brightness in general. By doing so, the screen will be less bright, and it will be more comfortable for your eyes to read, especially when you are using your mobile at night or in poorly lit areas.

The Roomba Mini comes in because of its size, but the experience is not just about that

by

My experience with him Roomba Mini It started in a rather unusual way for a robot vacuum cleaner: without that impression of being faced with something difficult to place. It may seem like a minor detail, but it is not. From the moment I picked up the box and took it with me on the Metro, it was clear to me that size was going to be an essential part of this story. Then, when I opened it, that intuition became certainty. The device is not only compact on paperit is also in the hand and in real space. It is light, easy to move and, above all, it feels like it was designed to fit effortlessly into everyday life. With the Roomba Mini, “the smallest cleaning robot in the world“, there is a second impression that comes right after that initial surprise, and it has less to do with the size and more to do with the way in which iRobot wanted to present the product. The mint finish, along with the other color options offered by the brand (black, white or pink), introduces a point of personality that is rare in this category, where almost everything tends to move in much more neutral codes. Added to this is a particularly easy installation: as soon as I take it out, I find a very guided, clear and fast process, one of those that allows you to go from the box at first power on in a flash. The Roomba Mini arrives with simple packaging Beyond what I found when I took it out of the box, the Roomba Mini also says a lot about the moment iRobot is going through. The brand, now in the hands of a Chinese companyhas chosen to respond to a market that is increasingly loaded with functions with a proposal that does not revolve around excessbut to containment. It doesn’t try to impress by size, but by fit. That is, in fact, the key to this launch. On paper, the idea sounds good: a 24.5 cm robot, a smaller self-emptying base and a set that is easy to integrate into a small home. In practice, however, this approach also requires resignations. A format designed to fit, with disclaimers included If I have been grateful for anything in this first contact, it is that iRobot has not complicated a phase that in many connected devices continues to cause more trouble than necessary. Here the implementation is quite direct. I download the app, connect the robot to the network, follow the steps that appear on the screen and, in a matter of a few minutes, everything is ready to start. The experience, at least at this point, is well resolved: there is a clear logic in the process and a constant feeling that the product is taking you by the hand without wasting your time. This helps a lot to ensure that the good initial flavor is not diluted just when it is time to really start using it. In my case, there is also an important nuance that should be made clear from the beginning: I have not tried it in a large home or in a house full of complicated rooms, but in a small spacejust the kind of environment this Roomba Mini seems to have been designed for. The map generated in the app makes it quite clear, with perfectly differentiated areas within a contained distribution. And that matters, because here it is not about asking it to perform miracles, but rather seeing if that promise of a compact robot makes sense when we put it to work in the scenario that, in theory, best fits it. The Roomba Mini incorporates a three-arm side brush for edges and corners, along with a central roller that is responsible for the main collection. From there comes one of the most important parts of the experience: seeing how the Roomba Mini reads the house. In my case, the mapping has been quick and, above all, quite precise when drawing the different areas of the house. Then I’m the one who decides how to label them in the app, but the basis on which the robot works is well built and makes a lot of sense. Here the ClearView LiDAR system plays an obvious role, because it does not give the sensation of improvising routes. And that matters a lot: because a well-resolved map is the foundation of this type of product. The Roomba Mini in action As soon as I put it to work, the feeling is quite clear: the Roomba Mini delivers. Its cleaning pattern makes sense, because it usually starts at the edges and then finishes the rest of the area. The power seemed enough to me for the daily maintenance of a small apartment like mine, but not for particularly demanding cleaning. It copes with dust, crumbs and light dirt, although it also exposes certain limitations fairly quickly. iRobot Roomba Mini Robot Vacuum Cleaner and Floor Mop with AutoEmpty Base (up to 90 days), LiDAR Navigation, 7000Pa Suction, Compact Design for Small Spaces, App, Scented Mops, Green The price could vary. We earn commission from these links Where I have noticed a clear advantage of this format is in the way the Roomba Mini moves through narrower or more obstacle-laden areas. Being smaller than other robot vacuum cleaners, it is easier to fit into gaps where a conventional model would fit more tightly, and this is noticeable on a daily basis. In my case, I have seen it maneuver quite easily between furniture and pass through areas where its small size clearly works in its favor. It does not make the robot a brilliant solution on its own, but it does give it an agility that fits well with the type of environment for which it has been designed. It is easier to slip into gaps where a conventional model would fit more tightly. That size reduction, of course, does not come … Read more

The more we calculate the size of the Universe, the less sense it all makes

by

We have known for a long time that the Universe is expanding. However, the speed at which it does so is a headache. Depending on which method is used to measure it, a different result is obtained. Now a much more precise way to measure it has finally been found, but it doesn’t really unravel much of the mess. It messes it up even more. An overlay of techniques. Through a superposition of different techniques, an international team of scientists has made the most precise calculation so far of the expansion speed of the Universe: 73.5 ± 0.81 kilometers per second per megaparsec. The figure coincides quite well with those that have been calculated in the past using data from the nearby Universe. However, it is quite far from what is calculated when data from the dawn of the Universe is used. This indicates that there is something in the physics of that furthest point in the cosmos that we have no idea about. Far from being solved, the mystery has become more complicated. A balloon that inflates. When we talk about the Universe expanding, we refer to the fact that galaxies are increasingly distant from each other. But not because the galaxies themselves move, but because the space between them widens. We can see it as a balloon on which a series of dots are painted. As the balloon inflates, the dots appear farther away, even though they have not moved from their place. Hubble voltage. Traditionally, the expansion rate of the Universe is calculated in two ways. Or by measuring the distances between stars and galaxies in the nearby Universe, or by measuring the cosmic microwave background. This is the electromagnetic radiation that remained as remnant of the Big Bang. That is, the oldest light that we can find in the Universe, since it was formed in the explosion with which it was formed. Therefore, the data is not taken from the nearby Universe, but from the most distant and ancient one, the one approaching the Big Bang. The figure obtained with both types of calculations should be the same. However, with the nearby Universe a speed of 73 kilometers per second per megaparsec is obtained, while with the most distant Universe a speed of 67 kilometers per second per megaparsec is calculated. This incoherence is known as Hubble tension. and indicates that, possibly, the Universe is expanding faster and faster. That’s why the closest one expands the fastest. This graph represents the tension that exists between measurements of the expansion rate of the late and nearby Universe, versus what would be expected based on measurements of the early Universe, specifically the cosmic microwave background. It could be a mistake. One of the hypotheses that seek to explain the Hubble tension is that, in reality, there is some error when measuring the expansion speed in the nearby Universe. There are many methods to calculate the distance between stars and galaxies and there could be an error. Therefore, an international team of scientists has decided to use a superposition of techniques to make a more precise calculation. Different types of stars. This method consists of simultaneously analyzing a large amount of data obtained from ground and space telescopes. These focus primarily on the brightness of Cepheid stars, red giants, supernovae, and galaxies of known brightness. The three types of stars mentioned are characterized by having a characteristic brightness, which is used to map the Universe and, therefore, also to calculate distances. With this superposition of techniques, the figure of 73.5 ± 0.81 kilometers per second per megaparsec was obtained. There is no mistake. When one of the superposition methods was eliminated, the alteration in the expansion rate of the Universe was minimal. The figure was practically the same. This indicates that the number has been measured perfectly. There is no mistake. So if the Hubble strain is not due to error, why does it occur? The mystery continues. After obtaining these results, the Hubble tension remains the prelude to a mystery. However, it is true that there are some hypotheses. For example, it is believed that the different figures in the distant and near Universe They may be due to the intervention of dark matter. There’s a lot we don’t know about her, so maybe it could explain what’s going on. On the other hand, there is the hypothesis that the Earth is in a place with spatial characteristics. It would be an area where there is relatively little matter, comparable to an air bubble in a cake. As explained in 2023 by one of the scientists who support this hypothesis, Indranil Banik“the density of matter is greater around the bubble, so gravitational forces emanate from this surrounding matter, attracting the galaxies in the bubble toward the edges of the cavity.” “That’s why they’re moving away from us faster than you would really expect.” Now we will have to solve that part of the mystery. At least we know that there is no error in the calculations and that the Hubble tension is a reality. Image | CTIO/NOIRLab/DOE/NSF/AURA/J.

We thought that the superpower of whales was their size. It’s actually the complex chemistry of your feces.

by

When we think about the baleen whaleswe usually imagine giant animals that sail the seas and feed on huge schools of fish, without much relevance to us as humans. However, they have been more important than we can think, being crucial when it comes to talking about the survival of our marine ecosystems. And all thanks to their excrement. What we knew. For years science has known that whale feces acted as a natural fertilizer top level. Now, a new study has brought to light the sophisticated chemical mechanism behind this ‘floating gold’. To understand its great importance, we must look at the base of the marine food chain that is in the phytoplankton. These are nothing more than microscopic algae that have the function of being the lungs of the ocean and the basis of marine life. The ‘problem’ is that to thrive they need iron, since without this mineral these algae cannot grow and could spell the end of all marine life. The feces. This is where enter the classic and revealing study led by Stephen Nicol in 2010, where something astonishing was quantified: the fecal iron measured in the whales was about ten million times higher than that of the Antarctic water that surrounded them. This was important because the whales functioned as a “biological bomb,” recycling and releasing about 50 tons of iron a year into surface waters before industrial hunting depleted their populations. But we were seeing that adding iron to the sea was not enough, since it tends to sink or become inaccessible quickly. So we were asking ourselves a logical question: how is this whale fertilizer made so effective? We already know it. The answer has recently come thanks to research published in Nature which shows how a team analyzed five fecal samples from baleen whales. Here they were able to discover that the secret of being such a good marine ‘fertilizer’ is not in the amount of metals they excrete, but in how they package it, since the feces contain high concentrations of what are known in chemistry as organic ligands. Its function. We can find that it is twofold, the first being the enhancement of the bioavailability of iron. This means it acts like molecular ‘tweezers’ that trap dissolved iron, preventing it from precipitating to the sea floor and keeping it in a format that phytoplankton can easily absorb. But in addition to this, it neutralizes the copper that is present in the ocean and that in high concentrations is lethal for this phytoplankton. In this way, the ligands present in whale feces bind to copper, drastically reducing its toxicity and creating a safe environment for algae growth. Its importance. In addition to being a very curious fact, the reality is that this discovery has changed our understanding of the biogeochemistry of the ocean. And, although we think that whales are not only consumers at the top of the food chain, the reality is that they are gardeners of the sea, since they fertilize the surface waters and protect the phytoplankton that is essential for the rest of the animals that live in the ocean. But these blooms not only feed the entire marine ecosystem, they also capture millions of tons of carbon dioxide from the atmosphere, helping to mitigate climate change. In this way, whale feces help their environment, but also us indirectly.

Science has been measuring whether size matters for years. A study with 3D simulation has the most complete answer

by

It is probably one of the most recurring questions in the history of humanity and, yet, one of the ones that accumulates the most myths per square meter. Leaving aside popular culture and internet forums, scientific literature has been trying for years to quantify what is true about the importance penis size. Science to the rescue. A published study This year, PLOS Biology wanted to resolve a question that has undoubtedly generated many jokes and also some complexes in the male sex. And the truth is that the short answer to this question is that size does matterbut perhaps not for the reasons most men believe. The signal theory. Until now, many studies were based on simple surveys to answer this question. However, this study has gone one step further by using 343 3D figures to evaluate the response of more than 800 participants. The goal was to understand penis size not only as a reproductive tool, but as an evolutionary signaling trait. The results. In the investigationfemale participants rated men as more attractive, which combined three factors: greater height, a “V” shaped torso (wide shoulders and narrow hips) and a larger penis. But there is a very important nuance. Attraction doesn’t follow a line of “the more the merrier” ad infinitum. The study in this case detected diminishing returns, since after a certain size, attractiveness does not increase proportionally, but rather there is a ceiling. Competence. But men also went through this study to evaluate the size of other men. In this case, it was highlighted that they perceived those with larger genitals as more competitive rivals and with greater fighting capacity. This suggests that, evolutionarily, the size could have served as both sexual ornament and a signal of status or threat towards other males, similar to the antlers of a deer. What they prefer. If we move away from evolutionary theory and go to stated preference, the baseline study remains the one published by N. Prause in PLOS One in 2015. This work is key because it differentiated, for the first time with rigor, between the type of relationship sought. In this case, using 3D models on heterosexual women, a preference was specifically shown for a slightly larger size, averaging about 16.3 cm in length in an erect state and 12.7 cm in circumference. But in the case of stable couples, the preference dropped slightly to 16 cm and 12.2 cm in circumference. The key reading. The first point to note is that circumference matters more than length in visual choice. The second is that these measures are only “slightly” above the population average. A mechanical reality. This is where science busts most porn myths. A narrative review published in the Journal of Sexual Medicine in 2023 analyzed the existing literature To answer the million-dollar question: does a larger penis give more pleasure? The answer is a very nuanced ‘it depends’. Science points out in this case that there are few high-quality studies that manage to directly link size with the organism, and the results are heterogeneous. But if we draw a clear conclusion, the truth is that the quality of the relationship such as trust or communication correlates more strongly with sexual satisfaction than the size of the penis. Male anxiety. If female preferences are moderate and satisfaction depends more on technique than size, why is there still so much anxiety among society? The studies in this case They point out that there is a great disconnection between reality and male perception, since approximately 38% of men report some degree of dissatisfaction with their penis. However, the vast majority of couples have a positive view of their partners’ genitals.

South Korea has designed a rover with wheels that change size to explore them

by

The dream of colonizing the Moon has been around since we set foot in it more than five decades ago. Settling on our satellite poses innumerable challenges; from how to get oxygen, what the food should be likeeven of course what is the best place to do it. We already have an answer to the latter: in caves. The problem is that you have to explore them first. A new rover. They count in Futurism that a team of South Korean scientists and researchers have designed a rover specially designed for the exploration of these lunar caves. The work has been published in Science Roboticswhich includes a video showing how the rover is capable of moving through difficult terrain, withstanding extreme temperatures and even being launched from a drone without suffering damage. The key is in the wheels. They are made up of metal sheets assembled to form a type of helix. The peculiar thing is that the wheels are soft and are capable of changing their diameter from 23 to 50 centimeters. This makes it much easier for you to overcome obstacles, enter smaller gaps when necessary, and also cushion falls. It is a very simple design, without hinges or bearings or complex parts; They simply fold or unfold by torsion, as if they were a spring. Moon cavesyes. As we said, there are many, but the main one is that the conditions are extreme. During the day, the temperature can reach 127ºC and at night it drops to -173ºC, which is not feasible. There is also the problem of long-term radiation. This is on the surface, but there is good news and that is that the Moon has a series of pits or caves where the temperature is much more stable, around 17ºC. A lunar tunnel. There is still more. By mid-2024 NASA discovered a huge cave in the Mare Tranquillitiatis crater, near the area where the Apollo 11 mission landed in 1969. It is estimated that the cave (actually a lava tube) measures about 45 meters wide and reaches up to 80 meters long, and the ground is also quite flat, so placing a settlement inside it could be viable. At the moment this cave has not been explored, although Solutions have already been proposed to do so. Artemis Program. Returning to the Moon is one of the most important space projects currently underway. Artemis It not only proposes setting foot on our satellite again, but also establishing our presence on it. The first unmanned mission was launched in 2022 and the plan is that Artemis II takeoff in February 2026. Artemis III will be the first manned mission, although this could still be missing several years. Image | Kaist In Xataka | We are sending cannabis samples to space.

four months at sea, kilometers of celluloid and a Trojan horse the size of a building

We already have here the first trailer for ‘The Odyssey’ by Christopher Nolan, which, as expected, offers us an adventure that moves away from the environments that the director has frequented until now, but which nevertheless has a good part of the house’s trademarks: musical fanfare, impactful images and dense and solemn atmosphere. a genuine deli for devotees of the director. After releasing a six-minute prologue a week ago Exclusive to 70mm IMAX theaters, this new trailer takes us to the immediate aftermath of the Trojan War: a devastated battlefield where Odysseus, played by Matt Damon, kneels before a fully armored Agamemnon (Benny Safdie) and which some critics have already pointed out as unequivocal proof that historical rigor is clearly not going to be one of the film’s priorities. From there, pure icons of classic adventure: the hero and his soldiers crossing forests, navigating rough seas and entering dark caves. Damon’s voiceover tells that “after years of war, no one could come between my men and home. Not even me.” Significantly, we barely see Odysseus on screen. The trailer gives a good account of Nolan’s visual ambition: we see the Trojan horse being dragged from the sea by hundreds of unsuspecting Trojans, and how the warriors inside the gigantic structure experience it. We see a giant creature at the entrance to a cave, perhaps the cyclops Polyphemus. We see ships suffocatingly tossed about by real waves. An ambitious odyssey ‘The Odyssey’ represents an unprecedented leap in the use of the IMAX format. It is the first film in history shot entirely with IMAX cameras.something Nolan has pursued since he began incorporating the format into action sequences with ‘The Dark Knight’ in 2008. Until ‘Oppenheimer’, technical limitations (excessive noise, prohibitive weight, difficulty capturing dialogue) prevented its continued use. But for ‘The Odyssey’, IMAX developed a new generation of cameras 30% quieter and considerably lighter, making full filming viable. Principal photography lasted 91 days between February and August 2025touring Morocco (Aït Benhaddou to recreate Troy), Greece, Italy, Scotland and Iceland. The most reckless: Nolan spent four months in the open seawith the entire cast rolling on real waves. The budget amounts to $250 million, making it the most expensive film of his career. Nolan explained. that sought to identify absences in contemporary film culture. He concluded that Greek mythology had never received the big-budget Hollywood treatment with full dramatic credibility. Furthermore, he states, The Odyssey by Homer contains elements of horror, mystery, romance and thriller simultaneously. It is not a genre, it is the matrix of all genres. It is clear that Nolan wanted to put the emphasis on the physical: real ships almost submerged in the sea, armies of extras, the Trojan horse… at the moment we do not see the abundant mythological creatures that the story has (the Cyclops, the mermaids, the sorceress Circe), but possibly they have sought to contrast with the realism of the rest of the story. And we still have to see the bulk of the star cast (Zendaya, Robert Pattinson, Charlize Theron, Lupita Nyong’o, Mia Goth…). This Odyssey has only just begun.

The James Webb captures a lonely object of the size of Jupiter devouring like a miniature sun

by

An international astronomer team has witnessed an extraordinary event: a lonely object, with a mass of just 5 to 10 times that of Jupiter, has entered a violent and prolonged growth burst. Using the combined power of James Webb Space Telescope (JWST) and him Vary Large Telescope (VLT) of the Southern European Observatory, scientists They have observed How this object, known as Cha J11070768-7626326, drastically increases its brightness and its “food” rhythm, behaving like a miniature star. The importance. This discovery represents the first time that a outbreak of accretion of type “exor”, a phenomenon so far associated with young stars, in a body of planetary mass. The finding is not only a milestone in astronomical observation, but also further blur the borders between what we consider a giant planet and a small star. The mystery. CH 1107-7626 is not a planet in the traditional sense that we all have in our mind. Although it has a mass comparable to that of a gaseous giant, I do not orbit any star and is 620 light years from the earth. Is what is known as an “free planetary mass object” or FFPMO (for its acronym in English). The existence of these lonely bodies raises a fundamental question for astronomy: are giant planets that were expelled from their solar systems, or are smaller stars that can exist in isolation? In order to solve this enigma that astronomers have right now on the table, you have to analyze the gas and dust disc that is around, as well as the way of accumulating the material. The fact that Cha 1107-7626 has an album and feeds on it suggests that its origin is more like that of a star. A cosmic feast. Astronomers observed Cha 1107-7626 in a state of calm in April and May 2025. However, for June, something had changed drastically. The object entered a “indulgence.” This means that its rhythm of ‘food’ began to increase, and in this way it reached a mass increase rate of 10-7 masses of Jupiter per year, the highest ever measured in a planetary mass object. As a result of this frenzy, the objective became between 1.5 and 2 brighter magnitudes in visible light and its optical flow increased between 3 and 6 times. This outbreak remained active for at least two months, since it was still on the end of the observation campaign in August 2026. But the most interesting thing is the speed it has. According to the observations made with the Vray Lark Telescope of the European Observatory, the growth rate is really aggressive, with a record rate of devouring 6,600 million tons per second of dust and gas. Great footprints. Beyond the increase in brightness, the telescopes captured detailed physical changes that reveal the nature of the event. A hydrogen emission line, known as Hα, developed a “double peak” profile with a red displaced absorption. According to the authors, this profile is a “distinctive brand” of the accretion channeled through magnetic fields, a process called “magnetospherical accretion” observed in young stars. But the most surprising finding was the change in the chemistry of the disc. At first, changes in the emission lines of the hydrocarbons molecules that came from the disc during the outbreak were seen. But water vapor also began to appear with a characteristic emission around 6.6 µm. This appeared during the outbreak where there was nothing before and is relevant because it is the first time that chemical changes of this type are observed caused by an increase in accretion. Relevance. This event classifies Cha 1107-7626 as the first “exor” of known planetary mass. Exor outbursts are significant accretion events that are considered key episodes in the early evolution of the stars. They can deeply affect the physical structure and chemical composition of the protoplanetary disk, potentially influencing the early stages of planet formation. Observing this process in such a small object demonstrates that the violent and fundamental mechanisms that the stars build also work at planetary scales. The study of Cha 1107-7626 offers an unprecedented vision of the accretion in the lower mass objects of the universe, providing a new window to understand how both smaller stars and the largest planets are formed.
