Extreme

up to 115 inches and the most extreme color accuracy

by

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.

If the question is what the European Orion module is doing among giant speakers, the answer is NASA’s extreme tests

by

When we talk about Artemis We almost always look in the same place: NASA, the SLS rocketthe Orion capsule and that plan to return astronauts to the surface of the Moon. It makes sense, because the United States leads the program and a good part of the space imagination continues to revolve around its missions. But that reading falls short. Artemis is not just an American story.It is also an international architectureand in that architecture Europe has a much more important piece than it usually seems at first glance. That role has just been realized in a very visible milestone. Airbus Space recently announced that ESM-3, Orion’s third European Service Module and the unit destined for Artemis III, had its four solar wings installed. It is a powerful image because it summarizes well the nature of the project: an American ship with an essential part developed on the other side of the Atlantic. The module, built by the aerospace giant for the European Space Agency, will use those wings to provide electrical power to Orion during its mission, although there is still work to be done before the assembly can be considered ready to fly. The ESM has a much deeper function than a picture of newly installed solar panels may suggest. In the Orion architecture, this module is placed under the capsule where the astronauts travel and concentrates systems that are essential for the mission. NASA explains that provides electricity, propulsion, thermal control, air and waterin addition to serving as support to the ship during flight. That is why its role is not understood as a symbolic contribution, but as an operational part of the vehicle. A test on the ground, between speakers and noise The following, however, was not one of those scenes that we immediately associate with space. Airbus Space noted on May 6 that the next step was an acoustic test, a ground test designed to see how the spacecraft responds to the extreme launch environment. Simply put: before thinking about docking, orbits or manned missions, the module had to deal with the noise and vibrations that occur when the rocket takes off. That trial has already begun to materialize. NASA has shown the Orion service module for Artemis III during its acoustic tests at the Kennedy Space Center, surrounded by a wall of high-powered speakers to simulate the sound and vibrations of launch. According to the center, these tests help measure how the structure responds, verify the physical integrity of the spacecraft, protect sensitive avionics and propulsion interfaces, and detect potential problems on the ground well before launch day. This type of test is known as direct field acoustic testor D-FAT, and involves surrounding space hardware with an array of high-power speakers to reproduce the acoustic environment of launch. In equivalent testing of the Orion European Service Module, ESA has spoken of more than 200 speakers and more than 140 decibels. It’s not a new rarity: NASA already submitted Apollo vehicles underwent vibroacoustic testing in the 1960s to see how their structures and systems responded to the noise and vibrations expected during flight. That this test has arrived now does not make the module a ready-to-fly piece, but it does mark another advance in Orion’s preparation for Artemis III. And there the context matters, because the mission in which this module must participate is no longer counted exactly the same as it was a few months ago. Artemis III was for a long time the mission associated with the return of astronauts to the lunar surface, but NASA has rearranged the calendar and now places it as a demonstration mission in low Earth orbit. The plan involves launching four astronauts in Orion, on the SLS, to rehearse rendezvous and docking maneuvers with one or two commercial lunar landing vehicles from SpaceX and Blue Origin. It is not the end of the lunar goal, but an intermediate step to test an architecture that still needs to fit many pieces. The interest of this module is best understood precisely because of this new role of Artemis III. If the mission will be used to verify docking and operations with commercial vehicles, Orion will have to act as a manned platform within a much broader test than a simple test flight. In this scenario, the ESM-3 is not a peripheral contribution, but rather an integrated part of the ship in which the astronauts will travel. Europe, therefore, does not appear only in the cooperation communications: it appears in the machinery that has to make the mission work. The paradox sums up the moment quite well. Europa has just completed a visible part of the preparation of the module that will travel with Orion, and its next test has not been on the Moon, not even in orbit, but among noise, vibrations and speakers within a test on the ground. That is also the reality of Artemis: large lunar objectives supported by a long succession of technical, industrial and often inconspicuous steps. In that chain, ESM-3 makes it clear that the return to the lunar surface is not being prepared only from the United States.

the extreme experiment in Greenland to test the human microbiota

by

The idea of ​​eating rotting meat sounds like a one-way ticket to the emergency room for a major stomach flu at best, but in the most extreme latitudes of the planet, it is a survival technique perfected over millennia. Now, explorer and chef Mike Keen a challenge has been proposed that defies Western physiology: feeding exclusively on decomposing seal for a month in Greenland. And all this to see how your microbiota adapts to this new diet and how grouper’social experiment‘. More than rotten meat. When we talk about the diet that Keen will follow on his expedition, the automatic mental image is that of meat left out in the open without any type of control. However, there is a crucial nuance, since the traditional inuit practiceslike the kiviak or the igunaq They are not just random rotting meat, but have gone through a fermentation process. What does it consist of? It is a controlled fermentation culturally, since for months these preparations undergo processes involving bacteria and very particular metabolites that science is just beginning to catalog. This fermentation not only preserves food during the long, dark Arctic winters, but, according to the researchers’ hypothesis, it could be key to the survival of the Inuit and extract vital nutrients in a diet based almost exclusively on animal products, lacking the plant fiber that normally feeds our intestinal bacteria. His secret. The scientific core of this type of diet is in our digestive system, since various studies have focused on the relationship between traditional fermented foods and the intestinal health of Arctic populations. Here, a study published in Microbiome on the Inuit gut microbiome showed that this is highly dynamic over time and is deeply shaped by the intake of traditional foods. In this way, unlike populations like ours, where the Western diet homogenizes the bacteria in the intestine, for the Inuit there are unique signatures. Centuries of history. Greenland’s dependence on seal meat is not a modern eccentricity, but a historical pillar. Historical records and isotopic analyzes have confirmed that even the Viking settlers in Greenland relied heavily on the seal for survival. It is a food that has been sustaining human life on the island for centuries. However, replicating this type of diet without traditional ecological knowledge carries a lethal danger, since poorly preserved decomposing meat is microbiological Russian roulette. Without the exact temperature control, preparation and anaerobic sealing that recipes like igunaqmeat becomes a breeding ground for serious pathogens such as Salmonella either Listeria that cause pathological conditions very serious. The experiment. By taking these foods, we hope to know exactly the metabolic adaptations that occur when these diets are taken and also to see how the microbiota changes when subjected to a 100% animal and fermented diet for a month. In order to reach clear conclusions, analyzes will be done on the feces, or blood, throughout this month of testing and also afterwards, to be able to have something clear about how its interior changes.

Marvel just gave 48 minutes of unfiltered violence to its most extreme character and you can watch it today on Disney+

by

Frank Castle, better known as the Punisher (or The Punisher if you’re an old-school comic reader), hasn’t had his own series for seven years. Since Netflix canceled ‘The Punisher’ in 2019, the character has survived on the margins of the MCU until ‘Daredevil: Born Again’ rescued him in 2025. Now Marvel has opted for a different format with him in ‘The Punisher: One Last Kill’. It is not a series or a movie, but 48 minutes of a borderline antihero, co-directed by Jon Bernthal himself and with a level of violence that Disney+ never allowed before. ‘The Punisher: One Last Kill’ comes with the “Marvel Television Special Presentation” label, a format that the studio premiered in October 2022 with ‘The curse of the werewolf‘. The format is a kind of laboratory: projects of between 45 and 60 minutes that function as self-contained stories without the pressure of sustaining a series for several weeks. Both ‘The Curse of the Werewolf’ and the Guardians of the Galaxy Christmas special worked as cult pieces, and with Punisher, Marvel has taken the experiment to the extreme, because its adult rating is the first on the platform for a Marvel Studios project. Here we will see how an unexpected force drags Frank Castle back into battle. The Punisher believes he has eliminated the Gnucci crime family, the last link to his family’s murderers, and the surviving matriarch, Ma Gnucci, comes to him not to negotiate but to settle scores. The first half of the episode focuses on visions that haunt Castle; the second is a real-time action sequence inside an apartment building reminiscent of ‘The Raid’. The idea for the series arose during the filming of the first season of ‘Daredevil: Born Again’. Bernthal asked the director for permission to develop something centered on Frank Castle. The two had previously collaborated, and that gave Disney confidence to have Bernthal co-write the script and serve as executive producer. Shot on real locations in Queens and Brooklyn, the photography is by Robert Elswit (Oscar winner for ‘Wells of Ambition’), a firm that visually elevates this bet far above a typical television film.

We had been searching for the origin of the most massive black holes for years. The answer is a cosmic carom of extreme violence

by

All black holes They are the fruit of a very violent activity. However, there are some for which the known processes are insufficient. Now, an international team of scientists has discovered how the most massive black holes in the Universe form. It is a process so violent that it needs a huge star cluster to support it. Two groups of black holes. This team of scientists has analyzed the LIGO–Virgo–KAGRA Gravitational Wave Transient Catalog (GWTC4), which includes 153 detections of black hole mergers through gravitational waves. By analyzing all the available data focusing on the spin of black holes, they have seen that all of them can be divided into two large groups. On the one hand, black holes of lower mass, which arose from an ordinary stellar collapse. On the other hand, very massive black holes, arising from secondary mergers in the environment of dense star clusters. Okay, now that you understand. Generally, black holes are formed when a very massive star that has already run out of fuel collapses. This gives rise to an explosion in which the outer layers of the star are expelled, leaving only a very dense core. It is so dense that it generates a great gravitational pull and nothing can escape from it. On the other hand, there are such massive holes that do not fit with this process. They are believed to be second generation black holes. That is, two black holes they merge and then the result merges with another black hole, becoming much more immense. That would be the second group that has been detected in the GWTC4 catalog. Something doesn’t add up. This black hole merger process is so violent that, as soon as the first merger occurs, the result would fly away like a rocket For it to stay in place and merge with a third black hole, something is needed to retain it. These scientists have discovered that these are densely populated star clusters. There are so many stars in them that the gravitational attraction of all of them keeps the black hole still in place. And what does spin have to do with it? Spin is a parameter that refers to the spin of black holes. When formed in the conventional way, the spin is predictable and perfectly aligned with the star that gave rise to the black hole. On the other hand, when they are formed by a process as violent as these consecutive fusions, the spin takes a random direction, but a value predictable from the sum of the spins of the rest of the black holes. These scientists, therefore, saw that all the data coincided with that hypothesis: consecutive mergers in the environment of a very populated star cluster. A forbidden zone. On the other hand, these scientists found a forbidden strip of stellar size in which black holes could not form. There are small or huge ones, but not medium ones. Although this is something that was intuited, the complete set of data they have obtained gives a twist to what is known about the formation of black holes. Relationship with nuclear physics. As explained by these scientists, this detected mass limit seems to be related to a series of nuclear reactions that take place inside stars. Stellar nuclear reactions are nuclear fusion. Humans have learned to control nuclear fission, but it poses risks that would be solved if we also mastered nuclear fusion. Until now It is being a complicated challengebut perhaps these new findings, obtained thanks to gravitational wave analysis, could shed a little more light on this research. Everything adds up.

launch one of the most extreme weapons ever devised

by

In 1961, the US Navy lost a nuclear submarine in the Atlantic and spent years trying to locate exactly what had happened under thousands of meters of water. That search left an idea among military strategists: the ocean could hide for decades technologies, accidents or threats capable of altering the global balance without anyone really knowing where they were. The return of weapons designed for fear. In the midst of the Cold War, both the United States and the Soviet Union came to study weapons so extreme that they seemed straight out of science fiction: nuclear torpedoes gigantic, underwater explosions massive or systems designed to destroy entire cities from the ocean. For decades, many of those projects remained relics of another era… until Russia decided to recover part of that logic with a new generation of “superweapons” designed to penetrate modern defenses and return strategic fear to the center of naval warfare. The submarine created around a weapon. He Khabarovsk-class is probably the most radical example of that idea. Russia has built a nuclear submarine whose main mission is not to patrol, escort or combat like a conventional one, but to transport and cast Poseidonthat gigantic autonomous torpedo with strategic nuclear propulsion and capability that we talked about before. In fact, everything in its design revolves around that mission. Their conventional capabilities They exist, but they are clearly subordinated to the true objective of the project: converting the submarine into a platform dedicated to deploying one of the most extreme weapons ever developed. Poseidon and the logic of the apocalyptic weapon. The truth is that Poseidon It is not really a conventional underwater drone, but rather a huge strategic torpedo designed to travel intercontinental distances underwater and threaten coastal cities, critical infrastructure or aircraft carrier groups. Russia presented in 2018 as an “invincible” and impossible to intercept weapon, trying to convey the idea that it can still develop systems capable of breaking any Western defensive shield. Beyond the propaganda, the concept is disturbing because forces NATO to prepare against autonomous underwater threats capable of operating over enormous distances and long periods of time. A design built for an idea. The new satellite images and open analyzes have shown that the Khabarovsk mixes elements of Russian submarines Borei and Belgorodalbeit removing entire parts to focus almost exclusively on Poseidon. The submarine maintains gigantic dimensions, a monster of about 135 meters longand probably carries up to six Poseidon torpedoes in huge compartments located in the bow. Among them there is hardly any room for conventional torpedoes, making it clear that Russia sacrificed versatility and multipurpose capability to prioritize this strategic weapon above everything else. NATO still doesn’t know how much naval warfare will change. Despite the grandiloquent tone with which the Kremlin presented Poseidonthe weapon still raises many questions about its real usefulness, its operational capacity and its true strategic impact. Some analysis considered exaggerated certain Russian claims, especially those related to apocalyptic effects or absolute impossibility of interception. Even so, and as we said, NATO navies are forced to take it very seriously because it introduces an extremely uncomfortable problem: how to detect and neutralize an autonomous underwater nuclear threat capable of operating at enormous distances and for long periods. Simply forcing the West to dedicate resources, surveillance and planning to this scenario is already a partial victory for Moscow. In the end, the Khabarovsk reflects an increasingly visible trend in Russian strategy: compensating for economic or conventional limitations by betting on radical systems, difficult to classify and designed more to alter the psychological and strategic calculation of the adversary than to wage traditional conventional wars.

For decades we believed that extreme nausea during pregnancy was caused by “hormones.” A large study found the real culprit

by

The beginning of pregnancy for many is associated with horrible nausea and vomiting that have become almost an inevitable and deeply annoying toll in pregnancy and that many women fear. And the reality is that, for a percentage of these women, nausea becomes a big problem and evolves into a very serious form called hyperemesis gravidarum. What was believed. At first, the most classic reviews They pointed squarely at the ‘hormonal dance’ that pregnant women experience while the placenta is forming. Here the peaks of human chorionic gonadotropin (which is the hormone that pregnancy tests detect), along with estrogens and progesterone, were the main responsible for this discomfort. However, in clinical practice, the exact cause remained uncertain, since it was not understood why some women only felt mild morning sickness and others ended up hospitalized due to the severe dehydration caused by vomiting. And the answer was in the DNA. A great study. Here science has dotted the i’s with an article published in Nature which has analyzed the data of almost 11,000 cases of hyperemesis gravidarum and contrasted it with more than 420,000 women who did not have this problem. The result. He targeted ten genes associated with this severe form of extreme nausea, but among all of them the GDF15 gene emerged as the main culprit. And here the different experts point out that the developing fetus and the placenta produce the hormone GDF15, which is produced from the gene that we mentioned before and sends it directly to the blood, causing this nausea. Although the key is not just how much hormone is produced, but the degree of prior exposure the mother had to this hormone before pregnancy. In this way, women who had low levels of GDF15 before becoming pregnant turn out to be much more sensitive to the sudden surge of this hormone from the fetus, which triggers the most severe symptoms of nausea and vomiting. A discovery with evidence. Despite the forcefulness that accompanies this evidence, the study suggests that the gene GDF15 It is the main cause, but not the only one. The fact that there are other genes involved demonstrates that hyperemesis gravidarum is a multifactorial condition so calling it the “sole cause” would be scientifically inaccurate, but classifying it as the most determining genetic factor is, today, a fact supported by the best peer-reviewed literature. What does it mean? Identifying GDF15 as the main biological switch of this problem is undoubtedly the first step to be able to apply a treatment that can help these future mothers who suffer from significant vomiting during pregnancy, and especially in the first trimester. Although it is true that this does not explain many other symptoms of pregnancy, such as heartburn or that some things begin to feel bad ‘just because’. Although there is still a lot of research ahead to discover them. Images | tirachardz on Freepik In Xataka | We have been sending pregnant women to bed for decades as a precaution.

Using multiple VPN hops is an extreme technique to leave no trace on the internet. This is how it works

by

Let’s explain to you How the multi-hop technique works in a VPNso that you know this method to leave no trace on the Internet when you browse. Because if one VPN It already offers you a layer of security and privacy, with this technique also called Multi-Hop you add more additional layers. This is a technique that is implemented in several commercial VPN services, from NordVPN even others of the best vpn services. But sometimes they can have somewhat different names and characteristics. Therefore, we are going to try to explain everything to you in a simple way. What is multi-hop in a VPN When you use a VPN, you are protecting your online traffic with a layer of security. This is done by passing your traffic through a server before it reaches its destination. This server sees and hides information such as your real IP, which makes your browsing safer. But there are times when this is not enough, and there are users who need additional layers of privacy. This is where the multi-hop technique comes in, which instead of sending your traffic through a single VPN server, routes it through two or more servers until it reaches the Internet. Imagine that you want to get from point A, which is your computer, to point B, which is the website you are going to visit. You can do it without further ado, in plain sight of everyone, or you can use a VPN which is like a tunnel where it is hidden from you and your browsing is made more private. Here, a multi-hop would mean taking several detours and several tunnels to make tracking you much more complicated. NordVPN with 76% discount The price could vary. We earn commission from these links Using this technique, your data is protected with several layers of encryption. Before leaving the computer or mobile phone, several layers are applied beforehand depending on how many hops you are going to have, and then each server decrypts its corresponding layer. It’s like putting it in a safe box to which only you know the key, but inside there is another box with another key, and inside another with another key. As if I were inside a Russian doll. This technique also change your IP address on each server to make it more difficult to track you. None of the intermediate servers will have full visibility. Meanwhile, the former knows where you come from but not where you are going, and the latter knows where you are going but not where you come from. And what’s the difference between a multi-hop or changing the VPN server manually? If you disconnect from one VPN server and connect to another, things like your IP and location change, but you’re still using a single server that knows where you come from and where you’re going, where your connection starts and ends. While, a multihop divides on two or more servers this information of where you come from and where you are going. You will have hidden more. Depending on the VPN service you have contracted or configured, this multi-hop can be offered to you in different ways. For example, NordVPN offers the option Double VPNwhich is a multi-hop on two servers. This doubles the encryption of your connection, and although it is less private than doing it on three or more servers, it means that your connection does not slow down as much. In short, this is a technique for those seeking maximum privacy, although It is not the only alternative. There are technologies like Tor network which do the same thing natively with at least three nodes, being the great reference for external anonymity. The difference is that Multi-hop chains together commercial VPN servers, while Tor routes traffic through nodes operated by anonymous volunteers, prioritizing complete anonymity over speed. You can go further by jumping between different providers Another thing to keep in mind is that multi-hop can be done within the same supplier or between different. Within the VPN provider itself, it is usually done with its own systems such as the aforementioned DobleVPN from NordVPN, a method that facilitates the process but allows the provider to have a theoretical global vision of the chain. While, doing it between different providers maximizes privacy. Doing this is more complex, as it is not natively supported in commercial apps. You would have to do this by setting up the router with a VPN and then using someone else’s software, or by using an intermediate VPS server. These are more technical configurations, although in exchange you get more privacy and security. No VPN service will have a complete view of your traffic, or if a service is hacked or has to give access to third parties through a court order, it will not have all of your browsing information either. It is for very extreme casesbut it is a possibility that exists. Multi-hop has two negative things The multi-hop technique adds as many additional layers of encryption and privacy as there are hops to different VPN servers you make. However, you already know what happens when when driving your car you deviate down several streets instead of going in a straight line: it takes you longer to reach your destination. This makes using this technique your connection is slower and has more latency. There is data which indicate that latency increases between 50 and 150 ms with each hop, while connection speed can drop between 30 and 60% per hop. This data can change a lot because they depend on aspects such as the distance between VPN servers, the protocols you are using, or the processing power of your devices. For example, jumps to geographically close servers each other cause less slowdown, while a jump between servers on different continents can severely penalize your browsing. However, although there may be changes, all this always ends up translating into The websites and apps you use take longer to loadwhere … Read more

CEO Toyota believes his extreme perfectionism is a problem

by

Japan is an extremely peculiar country. It is for many reasons in the eyes of a European. One of them is the mixture of humility at work and absolute dedication to the company to achieve a common objective that materializes in designing and producing the best possible products. The contrast is more complicated to understand if possible in the automobile industry. Toyota is considered the mother of what we know today as “toyotism”. A formula to work in a chain with a very limited stock. That is, without a safety net that allows unforeseen events to be handled with a warehouse large enough to support production until the problem is solved. This is achieved, of course, by building a chain that is oiled with the precision of a Swiss watch. But also with the certainty that what goes on the market is the best version of what each worker has in hand. Toyota revolutionized automobile assembly line production by giving the workers themselves the power to stop production if any failure was detected. It is a way of working that can only be carried out when, when developing the parts and design of an entire car, you work with the firmness of philosophy Kaizen. This Japanese word defines the pursuit of perfection through continuous improvement. This allows each modified part in the process of producing a new car to have the support of years of experience behind it. This way of working has been a competitive advantage until now has made Toyota the largest car manufacturer of the world. The company was, in 2025, the world’s largest automobile producer, with more than 11 million units manufactured. Volkswagen is second and remained at 9 million units manufactured. It is the result of production measured to the millimeter and reliability earned by hard work. That philosophy kaizen which Mazda or Toyota boast has allowed the latter to always be at the top of the reliability rankings, a value when it comes to putting millions and millions of units on the market. But this way of working has its drawbacks when you have to make agile decisions. China is the train to follow “If things don’t change, we won’t survive.” The phrase is from Koij Sato, CEO of Toyota, and is especially relevant because, as we pointed out, it comes from the head of the world’s leading brand. The message was sent to 489 suppliers with the aim of making them understand the importance of improving competitiveness against Chinese companies, they state in Automotive News. According to AutoblogToyota’s quality standards have been so strict that parts have been returned with small resin wrinkles that had no impact on a vehicle’s dynamics or reliability. The same thing was happening with thousands of wire harnesses that would have been returned because they showed minor signs of discoloration. Small aesthetic defects that buyers did not even notice because they are hidden inside the vehicle itself. Now Sato has asked its suppliers to be more flexible to save money on production and be more agile. The message launched by the company’s CEO is not coincidental. Months ago, a consulting firm specialized in reverse engineering I already alerted Toyota that their electric cars were designed as combustion vehicles and that penalized them when producing them. The problem is that, according to this company, producing an electric car is so different from a combustion car that it is almost equivalent to two different products even though both have four wheels and a steering wheel. They pointed out, for example, that Toyota used steel bars and reinforcements in the steering column or to hold the dashboard, thinking about reducing vibrations. However, Chinese manufacturers and Tesla choose to increased use of plastics because those vibrations are almost non-existent in an electric car. This allows them to produce cheaper and faster. And get lighter cars. “The average customer doesn’t even see these parts,” explained Shoji Nishihara, purchasing manager for Toyota’s vehicle development department, in statements reported by forumelectriccars. The final goal is complicated. The company aims to improve competitiveness by reducing production times and making the final quality of its products more flexible. A complicated balance if we want to continue being the reference in terms of reliability. For now, Toyota believes that its perfectionism was already bordering on healthy.

the birth of the most extreme magnetic monster in the universe

by

In the vast catalog of violent cosmic events, there are explosions and then there are superluminous supernovae, which are nothing more than the result of a stellar death which is capable of shining up to 100 times brighter than a conventional supernova, challenging our understanding of astrophysics for years, since it is not known where it can get so much energy from. Now we are getting an idea. What do we know? The big news in the world of astrophysics comes from an international team of astronomers who has been able to observe for the first time the live birth of a magnetar, conclusively confirming the link between these highly magnetic stellar corpses and the brightest supernovae in the cosmos. Where. The protagonist of this discovery is SN 2024fav, a type I superluminous supernova detected on December 9, 2024 and located in the Eridanus constellation about 1,000 million light years from us. And it’s not that it is a very common phenomenon, because watching this event is like looking for a needle in an intergalactic haystack. Finding this ‘needle’ is something very precious and that is why, in order not to lose any detail of this brilliant monster, the astronomical community mobilized a network of more than 20 telescopes around the world, including the fundamental contribution of the LOCGT. Thanks to this uninterrupted surveillance, scientists obtained the observational data necessary to reconstruct what was happening in the depths of the explosion. The relativistic screech. The question here is pretty clear: how do you confirm that there is a magnetar inside that expanding fireball? The first thing is to know what a magnetar is, which is nothing other than a very dense neutron star that has a magnetic field trillions of times stronger than that of the Earth. And it is not static, because when born after the collapse of a massive star it can rotate several times per second, reaching high speeds. In order to discover it, the researchers have named what gave them the key ‘relativistic chirp’. In this way, as the newborn magnetar rotates at the center of the supernova, its immense magnetic field acts as a brake, transferring its colossal rotational energy to the ejected stellar matter, causing it to shine with such extreme intensity. What they saw. From here, the researchers precisely detected the temporal signature of this external braking. From here, the light curve of SN 2024afav fit perfectly with the prediction of the energy loss of an incipient magnetar injecting power into the supernova, so we are facing the birth of a magnetar. Its importance. This discovery not only allows us to understand why certain stars say goodbye to the universe with a blinding brightness capable of eclipsing entire galaxies, but also opens a new window to study the behavior of matter subjected to such extreme magnetic fields that modern physics can barely replicate on paper.
