Sony has been quietly developing a technology for more than two decades that now, finally, has its own name and is ready to hit the living room. The Japanese firm has just presented its Sony Bravia 9 II, with which it claims to have made the most ambitious leap in its history in LCD televisions: an RGB backlight controlled LED by LED that promises color accuracy that until now only existed in reference monitors in post-production studios. Next to nothing. According to the brand itself, this new panel is not one more evolution of the MiniLED conventional blue LED, but integrates the three RGB subpixels in each LED diode, giving you greater control over the lighting and the resulting color volume. The Bravia 9 II arrives with the flagship label and new technology under its arm, but it doesn’t do it alone. Sony has also presented the Bravia 7 II with which it shares technology of True RGB display. More than 20 years cooking an idea: True RGB The history of new technology Sony’s True RGB begins in 2004, when the brand launched the Qualia 005, the first LCD TV on the market equipped with a Triluminos panel that used red, green and blue light sources to backlight the LCD panel. Twelve years later, in 2016, the brand took a new step in that evolution with the Backlight Master Drive system that I was riding the Sony ZD9which laid the foundations for the control over backlighting that later gave rise to dimming zones as we know them today. With the arrival of Bravia 9 II, the Japanese brand closes the circle of development after more than two decades, resulting in True RGB technology, which combines the RGB backlighting that the Qualia 005 brought to the table and the zone lighting control of the ZD9. Conventional MiniLED uses white or blue LED diodes grouped into dimming zones. True RGB replaces these diodes with others made up of smaller diodes that integrate a blue, green and red LED in a single capsule that are controlled independently, so that the light that reaches the LCD panel already does so with the color it should represent. This means that the light that reaches the panel is already, from the outset, purer and more accurate in terms of color, without the need for the panel’s filters to do so much correction work. In this way, the colors obtained are more intense and saturated even when very high brightness levels are reached, at which time the MiniLED technologies conventional ones suffer to maintain color fidelity. Sony Bravia 9 II, the benchmark of the range The reference model for Sony’s True RGB technology is the Bravia 9 II, which incorporates the most advanced of this RGB MiniLED technology with the lighting system RGB Backlight Master Drive Pro which incorporates new self-developed LED drivers that, according to Sony, improve the level of backlight control. This model also includes the technologies RGB Triluminos Max and Luminance Booster Pro to increase the volume of color and a softer gradation even in rooms with a lot of ambient light, something especially relevant for living rooms with windows or a lot of artificial lighting. Sony Bravia 9 II arrives with diagonals of 65, 75, 85 and up to 115 inches, making it one of the most ambitious proposals on the market in terms of size. The bet on these large format diagonals This is not a coincidence, but rather responds to one of the great advantages of RGB MiniLED technology: offering image quality and depth of blacks close to OLEDin a screen size unattainable for this type of television. On non-115-inch models, the screen includes Immersive Black Screen Pro screen treatment, a low-reflection, anti-glare coating developed with the participation of Sony Pictures Entertainment to ensure deep blacks and visible details even in dark scenes, in any lighting conditions. That is, less glare and reflections on the screen, without affecting color fidelity. A complete family with audio included The Bravia 9 II does not arrive alone. Sony presents it together with the Bravia 7 II, in which it applies the same True RGB technology, but in sizes of 50, 55, 65, 75, 85 and 98 inches, with X-Wide Angle technology to maintain color uniformity from wide viewing angles. Both the Bravia 9II and its little sister Bravia 7 II share features aimed at home theater, such as My Cinema mode, which adjusts the image and sound to your living room and image modes calibrated for platforms such as Netflix, Prime Video and Sony Pictures Core, as well as support for Dolby Vision, IMAX Enhanced and Dolby Atmos audioDTS:X. To complete the proposal, Sony presents the Bravia Theater Trioa three-speaker system (front left, right and center) developed in direct collaboration with the sound creators at Sony Pictures Entertainment. This sound system uses 360 Spatial Sound Mapping technology to generate up to 24 virtual speakers and create an immersive soundstage from all directions. Sony has not revealed the price of its new products, but all the products presented will be able to rbe kept from May 27.

the technological leap begins to fit when you see how the color changes

He Samsung R95H Micro RGB It was there, on, surrounded by the lighting of the room and with a very clear idea behind it: to show how far the company wants to take its new commitment to image. This morning, in Madrid, I was able to see it up close during a meeting with Samsung Electronics Spain in which Pablo Requejo, director of the TV Area, presented it as “the latest evolution in image technology.” We are not yet talking about a reviewbut a first contact to understand why the South Korean company wants this television to function as a showcase for its new Micro RGB bet, first presented at CES 2026. Here the first reasonable question appears: what is Micro RGB and why Samsung is giving it so much prominence. The name can lead to confusion, especially because it is very reminiscent of Micro-LED, a technology that we have been hearing promises about for years. But the difference is important. Micro-LED works without backlighting: each pixel emits its own light through small inorganic RGB LEDs. The OLED also emits light per pixel, but using organic compounds. Micro RGB doesn’t do that. What it proposes is to continue within the LCD field, but with a different backlight, made up of small LEDs that seek to improve color and light control. Requejo explained it from a very visual idea: “In micro RGB, each of the LEDs have the three native colors, red, green and blue.” The manager summed it up with another idea: by using Micro RGB, the company maintains that it can reduce dependence on traditional color filters and get closer to “spectacular colorimetry.” He also insisted on the size of those LEDs, “the size of a human hair”, a simple way to tell why Samsung wants to sell this technology as more than just a minor evolution. Technical sheet of the new Samsung R95H Micro RGB Samsung Micro RGB R95H panel 4K MICRO RGB LCD, 165 Hz VRR (100 Hz Native) resolution 3,840 x 2,160 sizes available 65, 75 and 85 inches image processor Micro RGB AI Engine Pro hdr HDR10+ sound 4.2.2 channels 70 watts (RMS) Dolby Atmos connectivity 4 x HDMI 2.1, 2 x USB-A, 1 x Ethernet, 1 x optical digital audio output, 1 x RF, 1 IC jack Wireless One Connect Ready compatible (for connections without visible cables) wireless connectivity Wi-Fi 6E Bluetooth 5.3 operating system One UI Tizen energy label Class E typical consumption 148 watts maximum consumption 390 watts dimensions 1658.8 x 1019.2 x 349.1 mm (with base) weight 31.8 kg (with base) price From 3,698.99 euros Micro RGB wants to open a third way between Mini LED and OLED The first image impression goes exactly where Samsung wants to take the conversation: color, brightness and sense of impact. As we can see from the photos, the 75-inch unit was not in a dark room, but in a demo with lots of light around, and yet the image did not appear washed out or washed out. The tones were strong and the panel conveyed that idea of ​​a high-end television that enters through the eyes before entering through the technical sheet. It remains to be tested with varied content and own measurements, but as a first visual contact it is convincing. Pablo Requejo, director of the TV Area at Samsung Electronics Spain, during the presentation of the company’s new range of televisions in Madrid Contrast was one of the sections that I was most interested in observing, precisely because this technology continues to be based on an LCD base. Live, the result was solid: blacks looked convincing, brightness didn’t seem to eat into dark areas, and the image maintained a reasonable separation between highlights and shadows. But this is one of those areas where a presentation is not enough. The night scenes, the subtitles on a black background, the viewing angles and the blooming They are tests that need time and specific content. Samsung bets on a sober base The version that we were able to see does not need a striking base to look like a high-end television. It achieves it in another way: with minimal frames, a very clean front and a simple central base that fulfills its function without taking the eye away. That decision makes a lot of sense because the important thing here is the screen, not what supports it, and Samsung seems to have sought precisely that: that the design accompanies without competing with the image. In the photos and live you can see that minimalist intentionwith the logo reduced to an almost testimonial presence. The reflection-free screen completes the proposal. In gaming, this Micro RGB promises. The presence of HDMI 2.1 It is important because it opens the door to improvements designed for very common problems when connecting a console or PC to the television. VRR allows you to synchronize the screen refresh rate with the signal from the console or PC to reduce cuts or jerks in the image. ALLM It can automatically activate low latency mode when it detects that we are playing. The Samsung logo is reduced to an almost testimonial presence, integrated into the lower part of the frame Added to that is a maximum refresh rate of 165 Hz, which means that the screen can update the image up to 165 times per second when the signal allows it. Compared to the traditional 60 Hz, the jump aims for a smoother imagewith less blur and a faster response, something especially useful in action, driving or shooting games. It is worth mentioning it because it is an important part of the technical section, but in this first contact I was not able to test it with a game: there was no console connected to the television. It will remain for a possible in-depth review to see how all this translates into real use. In software, the proposal goes through One UI Tizenthe layer with which Samsung wants to organize the experience … Read more

Hisense has found the key to improving the color on its 2026 Mini LED and Micro LED televisions: adding more subpixels

by

One of the challenges for television manufacturers is to evolve their technologies to improve their ability to represent color, without implying an excessive increase in production costs. Hisense seems to have found the key for its 2026 televisions to improve their image quality: add one more color subpixel to its matrix of Mini LED and Micro LED panels. The brand presented at CES 2026, which is being held in Las Vegas, two advances that seek to make colors more natural and precise: Mini LED evowhich adds a fourth cyan subpixel, and the evolution of its MicroLED panels with the RGBY Micro LEDwhich incorporates a yellow subpixel to its RGB matrix. Both changes allow televisions to better reproduce the most difficult-to-achieve color nuances. RGB MiniLED evo: cyan is the new white The televisions Current Hisense MiniLEDs They are based on thousands of small LED light diodes that illuminate the screen from behind, achieving better lighting control. This improves the contrast without sacrificing the brightness of the screen, being able to turn off more areas of the screen to achieve deeper blacks. In 2025, Hisense put on the table an evolution of that technology with RGB MiniLED, in which the white or blue mini LEDs were replaced by three RGB diodes (red, green and blue) to directly generate colorsinstead of using color filters as traditional LCD screens did. The MiniLED evo that Hisense has just presented goes one step further in this development and adds a fourth cyan subpixel to that RGB matrix. This intermediate color between blue and green helps reproduce complex tones that were previously only approximated by combining the three subpixels. Hisense’s solution is an adaptation to LED of what LG had been doing in its WRGB OLED panelsin which a white subpixel was added to improve brightness, although in this version the aim is to increase the color volume. Clear skies, water or certain skin tones look more natural and with softer gradients. In addition, local light management (local dimming) becomes more precise, reducing halos and poorly lit areas in scenes with high contrast. The introduction of this fourth subpixel increases the effective color gamut, achieving 110% coverage of the BT.2020 color space used as the professional cinema standard. Since, in essence it is an evolution (not a revolution) of the MiniLED RGB system that it already implemented last year in its top model, this new technology will be deployed to models ranging from 55 to 100 inches in a new UR9 and UR8 family, while the new MiniLED RGB evo panels will be limited to the 116UXS (which, as its name indicates, has a diagonal of 116 inches) as an evolution to the MiniLED RGB model of 2025. MicroLED RGB: three colors are no longer enough Along the same lines, Hisense has also presented improvements to the Micro LED RGB panels that it already presented in 2025 for its most premium range. As was the case with the Mini LEDs, the brand is committed to separating the color from the point of emission, replacing the blue or white diodes with three diodes that directly emit the RGB matrix. This is something that Samsung also has launched in its plans for 2026. However, in the variant presented by Hisense for 2026, a fourth yellow subpixel has been added along with red, green and blue, leaving an RGBY configuration. The yellow subpixel fills a critical gap in the spectrum that the three traditional colors cannot accurately cover. This addition improves the reproduction of warm tones and complex light transitions, such as those presented by skin, golden lights or sunsets, with softer and more natural gradients. For the moment, the new RGBY Micro LED is reserved for the 163MX RGBY model of no less than 163 incheswhich integrates millions of subpixels managed by a new processor and algorithms that balance brightness and color. The combination of greater precision in the backlighting provided by much smaller diodes and the incorporation of the yellow subpixel allows 100% of the BT.2020 color space to be achieved, bringing the quality of giant screens closer to those used in professional production. It’s a new era for LED The evolution that Hisense has presented is nothing more than confirmation that, although OLED represents an “affordable” way to obtain the best image quality, LED still has a lot to say in terms of quality and color volume. In the MiniLED evo, the addition of the fourth cyan subpixel allows intermediate colors between blue and green to look more natural, while in the RGBY microLED, the yellow subpixel improves the fidelity of warm and complex tones. In practice, these improvements translate into more consistent, natural and detailed images, without depending only on brightness or resolution. Hisense’s proposal for 2026 is presented more as an evolution in qualitative terms than as a revolution. It is a sign that the future of Mini LEDs and Micro LED involves optimizing the way colors are generated, using additional subpixels and controlling light emission with better processors and more refined algorithms.

The color of your Ethernet cable is not for decoration: it is a key visual language

by

We all have Ethernet cables at home and they are probably different colors. In my case, I have several yellows, but there are also red, blue, green… What many people do not know (myself included) is that colors are not a whim of the manufacturers, but rather They answer a practical question. A question of organization Contrary to what we might expect, the exterior color of an Ethernet cable will not tell us anything about its performance. If what you want is know the category of the cable (that is, the speed it supports), they all come with this detail printed on the cable itself. The color does not tell us if the cable is more or less fast, it is for something totally different: being able to distinguish and organize them better. In Xataka How to convert the antenna sockets in your house into an Ethernet network to bring Internet from one room to another. In a home it doesn’t make as much sense, but imagine a server or data center where Ethernet cables number in the hundreds or even thousands; If all the cables were the same color it would be crazy to identify them. Colors help manage large networks. Ethernet cable colors Although there are some guidelines on cable colors from organizations such as the IEEEand ANSIthere really is no universal color code for Ethernet cables. The meaning of each color can vary depending on the country, the sector and even the company. However, there are many similarities and widely used color patterns. These are the most common uses: Grey/white/black: These are the colors that we usually find for general home and office use. We see them in most routers. Blue: They are the most used cable for general network connections, servers or workstations. Yellow: They are usually PoE (Power over Ethernet) cables, that is, they provide power as well as connectivity. They can be used in IP cameras and VoIP phones. Green: to directly connect two devices such as computers, without an intermediate device. Red: They are usually reserved for critical connections such as security or emergency systems. orange and purple: They are less common colors. According to Cables and Kitsare used to connect systems that require a specific connection not compatible with the usual standards, for example to connect older systems that do not use Ethernet with newer ones that do. {“videoId”:”x8coltz”,”autoplay”:false,”title”:”ALL ABOUT ETHERNET CABLES_ TYPES, CHARACTERISTICS AND WHICH TO CHOOSE”, “tag”:”webedia-prod”, “duration”:”211″} As we said, the color of the cable does not determine its performance, but rather has a practical purpose for those who manage very large networks. With colors, maintenance time is shortened and serious failures such as the disconnection of critical systems are avoided. At home it can also be useful if you have several devices connected to your router and you want to clearly see which is which.

There are green, orange and even purple USB ports. The color rule that indicates your generation is extinct

by

There was a time when everything was easier. If the USB port was white, it was slow; if it was black, it was standard; and if it was blue, it was the fastest. That rule that helped us Easily identify USB-A generations It’s gone. The arrival of new standards, charging functions and brand marketing has meant that today we find a wide range of green, orange and purple ports that no longer mean much. Image: StorageReview The original color code. The current chaos, as we explain in our guide to the USB standardit was not planned. The USB-IF organization tried to standardize it: white corresponds to USB 1.x, black for USB 2.0 (480 Mbps), and blue (or turquoise) for fast USB 3.0 (5 Gbps). First confusion. That is a product of the charging ports: the first problem came when colors began to be used to indicate power functions, not just data transmission. This is how the yellow, orange or red ports arrived. These usually indicate an “Always on” or “Sleep & Charge” function, which means that the port continues to provide power even when the computer is turned off or in sleep. More speed, more colors. To differentiate USB 3.1 (10 Gbps) and 3.2 (20 Gbps), the standard suggested the color turquoise blue, or failing that, red. Here the system began to leak. And the final blow came from marketing. A purple USB cable for a Huawei device indicates that it supports SuperCharge, its fast charging technology. Image: Reddit The rule became extinct completely when the brands decided use colors as corporate identity. The most famous case is that of Razer, which dyes its ports a characteristic lime green. Likewise, if you see a purple port, it’s probably from Huawei. The Chinese manufacturer uses them to identify its devices compatible with SuperCharge (its fast charging system), although technically it is still a USB 3.1 port. Chaos also in names. If there is already a mess with the colors, there is also a mess with the names: USB-IF itself has contributed by renaming the standards. USB 3.0 was renamed “USB 3.1 Gen 1” and is now “USB 3.2 Gen 1.” In parallel, USB 3.1 is now “USB 3.2 Gen 2”. This makes it almost impossible for a user to know what they are buying without looking at the fine print, a mess that the Wi-Fi Alliance solved much more elegantly. with standards such as Wi-Fi 5, 6 or the most recent Wi-Fi 7. The real culprit: USB-C. The final nail in the color coding coffin is the USB-C connector. It’s just a reversible connector, but what’s inside is chaos: the same USB-C port can be a slow USB 2.0, a USB 3.2 or a very fast Thunderbolt 4. The only way to differentiate them is to look for the lightning bolt logo that characterized Apple. Or read the device’s spec sheet because color, unfortunately, no longer means anything.

plasma in a nuclear fusion reactor, in color and at 16,000 fps

by

Seeing the inside of a nuclear fusion reactor is, for obvious reasons, complicated. We are talking about temperatures of millions of degrees Celsius, hotter than the core of the Sun. However, the British company Tokamak Energy has just given us unprecedented images of what is happening inside its ST40 spherical reactor: a video in full color and at the incredible speed of 16,000 frames per second. An unprecedented ballet of colors. What we are seeing in the video is, in essence, the choreography of the elements within the tokamak. The ST40, like most of these reactors, uses hydrogen isotopes (deuterium in this case) as fuel. When this gas turns into plasma, it emits a characteristic pink light, which dominates the scene. But the interesting part begins when researchers introduce lithium, which glows red. And no, this is not just a visual spectacle. Every color, every bright filament we see in these images, is a gold mine of information that is helping scientists solve one of the biggest challenges on the long road to commercial fusion energy: how to tame plasma so that it does not degrade reactor materials. What exactly are we seeing? In the images, we see how small granules of lithium are injected into the reactor chamber. Upon entering the outer, colder areas of the plasma, the neutral lithium is excited and emits an intense crimson red light. As they penetrate the hottest and densest regions, lithium atoms lose an electron, become ionized (becoming lithium ions), and begin to glow greenish. Once ionized, lithium no longer moves freely. It is forced to follow the invisible, but very powerful magnetic field lines that confine the plasma. Those green filaments that we see dancing in the video are, literally, the lithium drawing the magnetic cage of the reactor. What is all this for? The lithium acts as a protective shield for the reactor. Recording what happens in color is not easy, but it helps identify whether the impurities that Totakak Energy is introducing into the reactor radiate in the expected place. And if the lithium powders penetrate to the core of the plasma. This experiment is part of research into a mode of operation called the “X-point radiator” (XPR) that uses elements such as lithium so that the edge of the plasma radiates and loses a large amount of heat before touching the reactor walls. It is a protective “atmosphere” that cools the plasma just at the last moment, reducing component wear without sacrificing core performance. The advancement of Tokamak Energy. This approach is the centerpiece of the Dell ST40 upgrade program, which has received funding from the US and UK energy departments. The goal is to coat all the components that face the plasma with lithium, a technique that has already been demonstrated in other laboratories, such as Princeton, to improve plasma performance. This type of visual diagnostics complement the incredibly complex systems that are being installed in reactors such as the JT-60SA in Japan, the most advanced tokamak in the world currentlywhich uses lasers to measure plasma temperature and density indirectly. A global career. While colossal and institutional projects such as ITER They mark a long-term pathwhich plans its first deuterium-tritium experiments by 2039, more agile companies like Tokamak Energy are exploring new designs and technologies, such as spherical tokamaks and high-temperature superconducting magnets, to accelerate the arrival of commercial fusion. The closure of the historic JET reactor in the United Kingdom, who said goodbye breaking an energy recordmarked the end of an era, but its legacy is the foundation on which all these new advances are built. This new window into the heart of plasma is not only visually impressive. It is a small step that brings us a little closer to the goal of replicating the energy of stars on Earth. Nuclear fusion just got a lot more colorful, and that’s great news. Image | Tokamak Energy In Xataka | While the West still waits for fusion energy, China has found a shortcut

If your intuition tells you that “more intense color are richer,” science has good news for you

by

Cardiovascular diseases follow being the main cause of death in the worldbut this scourge can begin to control thanks to the most colorful foods of the supermarket. A new and thorough review study systematic published in Nutrients has put the focus on carotenoidsthe Natural pigments that give their vibrant color to fruits and vegetables such as tomatoes, carrots or spinach. What are exactly carotenoids. Carotenoids are a group of more than 600 compounds that plants, algae and some bacteria produce naturally. They are responsible for the red, orange and yellow tones of many foods. Among the best known we can highlight the lycopene that is very present the tomatoes, the beta-carotene that is in carrots (and can get to give us an orange color on the skin) and the Lutein o Zeaxantine that are in green foods. Components of great importance for humans. Humans cannot produce these carotenoids, as with some vitaminsso we depend on the diet to obtain them. But his fame is not free: they act as Powerful antioxidantsneutralizing the free radicals they produce Oxidative stress and ends up damaging the cells and the genetic material itself. In addition, the study highlights its anti -inflammatory properties or its ability to improve the cholesterol profile by reducing oxidation of ‘bad’ or LDL cholesterol. This is something very relevant, then The oxidation of LDL is the trigger to form the atheroma plates In blood vessels, which is a key risk factor for Atherosclerosis. That is, the hardening and obstruction of the main arteries of the organism that can finally cause a heart attack. Evidence on the table: real food vs. supplements. The researchers, led by a team from the European University of the Atlantic in Santander, analyzed 38 of the most relevant studies published in the last decade to answer a key question: does the carotenoid intake prevents cardiovascular diseases? But beyond this, they also wondered if The supplements that can be found work or a varied diet is better. Having them in blood is associated with a healthier heart. The observational studies of cohorts that followed large groups of people for years, are quite consistent: those who had higher concentrations of serum carotenoids presented, in general, a lower risk of cardiovascular disease. Specifically, there was an inverse correlation with hypertension, the rigidity of the arteries and several inflammation markers. This suggests that a usual consumption of rich foods in these compounds is a good cardiovascular health indicator. Do carotene supplements work? This is where the thing is complicated. The studies that gave the participants carotenoid capsules showed results that were often contradictory. On the one hand, when the lycopene was given in supplement, he recorded an improvement in the endothelial function of patients who already had cardiovascular disease, but not in healthy volunteers. In the case of lutein, a triglyceridesand with beta -carotene the significant effect was null. This is something that surprised the researchers, but even more they were amazed to see that by providing several carotenoids together the effect was more effective than with the use of an isolated carotene. This already gives us an important clue. Real food wins the game. The clearest verdict came from dietary intervention studies. When participants were provided with foods such as tomato or carrot juices, or they were indicated to increase the consumption of fruits and vegetables in the diet, the benefits were more notable and consistent than with the pills. Interventions with tomato juice in lycopene managed to reduce key inflammatory molecules in atherosclerosis, while increasing the consumption of fruits and vegetables improved antioxidant capacity of “good” or HDL cholesterol. In this way, scientific evidence suggests that carotenoids have to be consumed in ‘groups’ to have a greater effect. The conclusion is clear: we must not replace the vegetable. On many occasions we try to supplement what we do not like with herbalist treatments. This is not ideal in this case, since the cardioprotective effect of the carotenoid seems to be amplified with other compounds that the original food such as fiber or vitamins presents. But it also adds to the need to complement it with other fruits and vegetables. And you don’t have to become obsessed with tomato and carrot in this regard. There are a lot of fruits and vegetables that can be included in the diet in a varied way so as not to end ‘hating it: peppers, pumpkin, broccoli or kale are some of the examples we find. Time is vital for your protection. As in medicine, the effects are not usually immediate when a change in the habits of a patient is made. In this case, long -term observational studies show the strongest results, that is, It is the sustained habit of consuming these foods What really protects the heart. A good diet is fundamental. This conclusion is no secret to us, since there are many studies that point to important benefits of following a good diet. For example, the Mediterranean diet It can help us stop the aging of the brain. Although it is also a reality that there are many diets such as potato diet either Miracle diets In general, they are a pathology to face it in the absence of nutrients or a subsequent rebound effect.

We have centuries studying the different types of clouds. What tells us the shape and color of these atmospheric phenomena

by

The atmosphere of the earth hides about 12.9 billion liters of watermore or less. And a good part of that water is in huge clouds that we see fly over our heads as if nothing. These huge atmospheric objects captivate our imagination in childhood, but we often stop thinking about them during our day. Knowing them can help us pay attention to them. What is a cloud The clouds are essentially water, a lot of water. Steam -shaped water, small drops and Even small ice crystals that remain in suspension in the atmosphere. This water becomes visible when condensed, generating a contrast with the blue of the sky. The clouds circulate in the atmosphere dragged through the differences in pressure and the wind that they generate. They also move as a result of the land rotation itself, since the solid surface of the earth does not rotate in the same way as the atmosphere. The clouds can be of very different types that we classify according to certain conditions, such as the height to which they occur. For example, when the clouds are formed at surface height, we do not even usually refer to them as such, but as a fog. But the fog is still a type of cloud. How a cloud is formed The atmosphere keeps water vapor, small H2O molecules that are mixed with the other gases that make up the atmosphere. The amount of water that the atmosphere can store in the form of gas depends on factors such as temperature and pressure. There is a threshold from which the atmosphere Water “sat”and that is when this water can begin to accumulate. This accumulation is good when the amount of water increases or because atmospheric conditions make the threshold reduce, and implies that the molecules go from being a gas in suspension to form microscopic water drops. When these drops, still in suspension, accumulate, the clouds are formed. Types of clouds and characteristics The clouds are usually classified according to two fundamental characteristics: Your altitude in the atmosphere and its appearance. According to its altitude, three types of clouds are distinguished (with an additional case), groups that the State Meteorology Agency (Aemet) call of “high floor” (the highest altitude), of “middle floor” (intermediate altitude) and those of low floor (those of minor antura), to which we must add the clouds of vertical development. There are different terms with which referring to these clouds, for example we can speak sympleously of high, medium and low clouds. High floor clouds The high -floor clouds are those that are at heights between 5 and 13 kilometers on the ground, and include cirro, circoum and cirrostrates. Cirrus: According to Explain Aemetcirrus are clouds of the high floor, separate and “in the form of white and delicate filaments, or banks or narrow, white or almost white bands.” Cirrus. Piccolonamek, Commons. CIRCOUM: It is a thin layer of clouds, white and shadowless, “very small elements” in the form of grains or undulations. Circummers. King of Hearts. CIRROSTRATE: These clouds for their part acquire the appearance of a “cloudy veil”, also transparent and rather white, only that this type of clouds covers the sky, totally or partially, producing “halos.” Cirros and its characteristic halo. SeanMack Medium floor clouds The clouds of the middle floor are located at heights between two and seven kilometers, and can also be of various types: altocumulos, high, and nimbostratos. Altocúmulos: The altocumulus are already located at medium heights. It is a bank or cloud layer that can be white or gray. Its structure can varybeing formed by “tiles”, “rounded masses” or “rollers”, structures that, in turn, can be “partially fibrous or diffuse,” Explain Aemet. Altocumulos. Bidgee Altostrates: This layer of clouds usually has gray or bluish colors, it can also have a fibrous appearance, it is characterized by totally or partially covering the sky allowing to distinguish vaguely, but unlike cirrostrates, it does not produce halos. Altostrates. Famartin. Nimbostrates: These clouds form an already dark gray layer, with “appearance veiled by rainfall or snow precipitation”, rainfall that usually falls from it more or less continuously. Nimbostratos. Famartin. Low floor clouds The low floor clouds are those located at heights of up to two kilometers and can be of two types: strata and strata. Stratocumulous: Again clouds that can acquire a gray color, or, on other occasions, whitish with dark parts. Stratocumulous. DjClimber. Strata: Generally gray clouds, uniform base (relatively), which can produce drizzle. The halos in this cloud only occur when very low temperatures are reached. Strata. Couch-Scratching-Cats. Vertical Development Clouds Finally, vertical development clouds can also be of two types: clusters and cumulonimbos. Clusters: These are clouds that arise in isolation, dense and well -defined contours. These clouds develop vertically with the form of “protuberances”, “domes” or “towers.” Clusters. Piccolonamek. Cumulonimbos: Finally, the cumulonimbos are clouds that Aemet describes as “Amazacotadas and Dense”, of vertical development “in the form of a mountain or huge towers.” On his cusp, a top “smooth, fibrous or striated.” Cumulonimbos. NOAA/AOML/Hurricane Research Division. How much water is there in a cloud? The clouds are ethereal objects, “cotton” and with a density low enough to keep afloat at a certain height in the atmosphere. However, they are also huge, so the amount of water they can house is enormous. A few years ago, a group of researchers proposed answer the question How much water is in a cloud. The truth is that the answer can vary greatly since the volume of these atmospheric phenomena can be the most diverse. However, the team made an estimate based on a 0.5 grams of water per cubic meter of cloud. The team took as reference an average cluster, an cloud that would have a cubic shape and a kilometer long. The result: this imaginary cloud would contain about 500 tons of water. Larger clouds, of course, would be able to house an even greater amount of water.

BOOX GO 7 Y GO COLOR 7 (2nd generation), characteristics, price and technical file

by

Not everything in the world of readers of Electronic books is Kindle, Kobo either Remarkable. For years, Boox has been stepping hard in this segment, with proposals as interesting as An e-reader with surface soul And even another integrated into a mobile phone. The Chinese company has decided to close April by renewing its GO 7 series. We talk about the GO color 7, which premieres second generation, and the new Go 7, which is committed to a monochromatic screen. Both share an elegant and minimalist design. Two readers where what stands out is writing The great novelty of this generation is the capacity for writing, which makes these devices more than simple readers: they want to occupy an active role in creativity. Both are compatible with the New Box Inksense pencilwhich is sold separately. We will have to see how they behave on a day -to -day basis, but the idea is clear: take notes, make sketches, underline texts and organize ideas directly on the screen. It is not the first time that Boox is committed to digital writing, but here he redoubles the bet. As for visual experience, the GO color 7 (2nd generation) incorporates an Eink screen 7 -inch kaleidowith 150 ppp color and monochromatic content at 300 PPP, ideal for those who seek the best of both worlds: nuances of color without giving up the sharpness. Go 7, on the other hand, mounts a monochromatic screen of the same dimensions, based on letter 1300 technology, also with 300 PPP resolution. Both include adjustable frontal light to adapt to any reading environment. As can be seen in the images, the two models have physical buttons On the right side, discreet and well integrated, designed to turn page or move without playing the screen. The frame is fine, but enough to hold them firmly. The general sensation is lightness and precision. Both devices share a good part of the technical file: 190 grams of weight, 4 GB of RAM and 64 GB of expandable internal storage using microSD. They work with Android 13 and offer full access to Google Play, which greatly expands their possibilities. Price and availability of Boox Go 7 and Go Color 7 (2nd Generation) The new Box Go 7 and Go Color 7 (2nd Generation) They will be available from Friday In Spain through the official online store. For now, we are waiting to know their official prices in the country. Images | BOOX In Xataka | I’ve been reading books on the mobile for years.

Only five people in the world have seen this new color. The trick: laser in the retina

by

It is estimated that the human being is able to see around ten million different colors, According to the American Academy of Ophthalmology. This is what we know as a visible spectrum, that is, those wavelengths to which Our eyes respond. Although there are exceptions, we all see more or less the same, but since last Friday there are five people in the world capable of seeing a color that the rest of mortals cannot see. The key: very precise laser surgery to stimulate concrete retin cells. Context: How do we see? As we said before, our eyes see the visible spectrum, that is, the wavelengths between 380 and 750 nanometers. Below the 380 we have ultraviolet light and above 750 infrared. This is possible thanks to some cells located in our retinas called cones, photoreceptors that react to concrete wavelengths and send signals to our brain, which is responsible for processing everything: Cones S: short wavelengths, that is, the blue. Cones M: Medium wavelengths, that is, the greens. Cones l: long wavelengths, that is, the red ones. S, M, L and all together. The cones do not react only to a concrete and exact wavelength, but their ranges overlap. The M cones will react to the longest blue wavelengths, as well as the S s will react to the shortest green zone lengths. According to Ren NG, Professor of Electrical Engineering and Computing Sciences of the University of California, “there is no light in the world capable of activating only Mons M. If they are activated, be sure that one or two more types will be activated too.” The experiment. In the above is the key to the experience whose results were published last Friday in the Science Advance Magazine. What if we manage to stimulate concrete cones alone and exclusively? That was what the researchers from the University of California did: map the retina, look for cones m and excite them with small doses of light, laser. It is a technique baptized as Oz, in honor of ‘The Oz Wizard‘And the Emerald city. This is the closest representation to the “Olo” color that can be made on a screen | Image: Xataka OLO. After undergoing the experiment, the study participants were able to see a new color they called “Olo.” Of the five participants, three of them were co-authors of the study (the aforementioned Ren NG was among them) and two were colleagues from the University of Washington. This “Olo” is defined as “a bluish green with unprecedented saturation.” According to NG, the closest way to represent “Olo” on a screen is with the Hexadecimal #00FFCC, but with saturation that we cannot understand why, literally, our brain has never received that signal. The closest way to represent “OLO” on a screen is with the Hexadecimal #00FFCC How to verify it? To verify that all participants saw an alien and hidden color to the rest of mortals, made chromatic correspondence experiments comparing “Olo” with a bluish green laser that saturated or unraveled by adding white light. Everyone agreed that adding white light to “Olo”, Ergo unleashing it, the color of the laser was achieved, thus confirming that “Olo” is outside the visible spectrum of the human eye. And for what? It is an excellent question. The reality is that, for the moment, it does not have a practical utility beyond demonstrating that the procedure works. In Scientific American They collect the testimony of the principal researcher and his team, which imagines some screens capable of scanning retinas and broadcasting images and videos in impossible colors. However, it may make more sense in other lands. For example, allow the blind people to see certain colors or “simulate”, in quotes, how you see an animal in our own eyes. The problem, of course, is that the Oz effect is temporary, not permanent. Cover image | Amanda Dalbjörn In Xataka | All the colors you see on the web are wrong. And your browser has the fault
